The hairdryer consists of a motor, fan, heating elements, an electrical circuit forcing items to work consistently. Depending on the number of modes, the manufacturer, the element base, appearance, the composition of the switches are different. But nothing more complicated by a semiconductor thyristor, inside will not be. Therefore, we will carry out home repair hairdryers for hair with your own hands.
The housing is kept on screws. Heads often non-standard sample. It is a plus sign, an asterisk, forks. Consequently, first of all, before fixing the hair dryer, we take care of a tool that can cope with such a task. Fortunately, a set of bits is worth 600 rubles today.
Sometimes the housing sash is additionally attached together with special latches. This is a separate problem: experienced masters often break plastics, desperately cope with civilized methods. No wisdom, invent hidden screws, hidden under stickers, plastic inserts, removable lids of regulators. Fictive fasteners. Useful functions are missing.
The hair dryer is powered by a constant current 12, 24, 36 V. To straighten the network voltage, a diode bridge is used, in cheap models - a single diode. Filtering the harmonic power is carried out by a capacitor included in parallel engine windings or part of a more complex filter. Inductance due to exorbitant mass in the phenomena is rarely used. Therefore, the knowledge of the principles of smoothing ripples RC chains will be enough to cope with the construction of a concept of repaired hair dryer. Sometimes one spiral (inductance) is used by the filter element.
The dryer switch simultaneously closes the chain through which the helix will eat, starts the motor. Further intervention schematics is determined by the complexity:
In most model, the phenomena is preferred in parallel with the inclusion of heaters with an inactive motor. Cuts a spiral.
Optionally, the ambient thermostat in the form of a special resistance or other sensitive element. We describe the breakdowns of the faithful assistants of the beautiful half of humanity.
If the device is deprived of signs of life, it is unstable, the inspection begins with a power circuit. The repair of Rowenta hairdryers is described below.
Attention! The types of work require an electrical appliance skills. The authors reset the responsibility for damage to health, property that has arisen when trying to follow the recommendations for the repair of phenomena.
The inspection of the power wire begins the outlet. There is part of the faults: there is no voltage - the hairdryer does not work. If the voltage is present in the outlet, the inspection of the cord begins the entrance to the housing, go towards the fork. Works are performed on a de-energized device. A visual search for fuses and irregular formations - burners, insulation damage, fesomes are underway.
Then the body of the hair dryer is sized. Inside, you have a chance to see the electrical resistance options:
The last element of the list characterizes an unbalanced compound, therefore, an archus poster for testing. Skillful hands, or rather, smart heads, Ukrainian brothers in mind are advised to use an ordinary needle to repair a hairland. Immediately catching the thoughts of the thoughts of the next paragraph will skip, directly start testing.
Repair of a hair dryer begins with handwriting. Chinese tester, light bulb, indicator. A needle is attached to one terminal, then stuck in the core in the area of \u200b\u200bthe cap through insulation before copper. The second terminal is feeling the legs of the fork. The call passes for both lived. Over 1 puncture on the core when you repair a hair dryer should not do (some will try to look for the breakpoint), since the nature of the exploitation involves moisture from wet hair.
Catch the wire, having visually visually distinguishable points of docking, even a child will be able. Having found damage, it is recommended to buy a new cord equipped with a fork of an unbalanced design. The likelihood of moisture gets restricted selection of insulation of conductive parts used in order to repair the hair dryer.
Cases are common: first glance reveals the place of damage to the cord entry into the case. Sleeps, NAAR, black insulation indicate the localization of malfunction.
A vulnerable point of wiring was sheltered at the junction with the body of the hair dryer. The hostess takes a gentle device for the cord, winds from side to the side, screws the cable to the handle. I lived with a crack spark, insulation heats, burns, copper melts. Such is the mechanism of damage to copper lived.
When replacing it is useful to close the switch switch, check: will change the hairdryer in response to a simple behavior's behavior. There are three-position switches, each position in the short-circuant state is checked separately. Remember, sketch the initial layout of the wires before starting the package of the hair dryer.
Checking speed switches, temperature uses a similar scheme.
The defective element detected during the restoration of the hair dryer inspect. Nagar is considered supfil, skurt, eraser. Contacts are cleaned with alcohol. Faulty components are replaced by equivalents. The radical method is to close the switching button for the spice for the search for suitable components.
Really often, the hair dryer is clogged. It is necessary to remove the filter, if any, and clean carefully. Soft tassel Remove dust from gaps.
The lack of rotation of the blades or low revs are often observed when the hair is wound on the axis of the engine. Propeller must be carefully removed from the shaft, in every way avoiding extra effort and distortion. After that, foreign items are removed.
The hair dryer is usually several. Visually, they all should look homogeneously. Ensure that when fixing the hair dryer, open the case. The discovered breaks are eliminated by the twist ends, soldering and tinning. You can also get thin copper tubes and enhance the ends of the torn spiral inside.
Defects of heating elements when repairing is observed visually. Attentive inspection will tell you how to fix the hair dryer. Effective replacement of spirals similar to purchased or homemade products From nichrome wire.
The electrical engine of the hair dryer can be powered both by constant current and variable. If the diode bridge burned down, the windings are damaged, normal functioning is broken. A terrible crack and sparks when turned on indicate the malfunction of the motor.
Engine windings are dropped when the hair dryer is repaired. Each wire find a couple that is called. Conclusions are connected by three, none should hang in the air. Replacing the winding during the repair of the hair dryer is made only in the workshop. However, folk masters are worse than the machines. Those who wish will try.
With the health of the windings, brushes are inspected, the copper surface is underponing under them, the density of the fit is estimated.
The axis should spin freely. With the repair of the hair dryer, it will not hurt to lubricate rubbing surfaces, manually to work problem areas.
The substrate from Ghetynaks is sometimes cracking, breaking down the path. Damaged plot will be prompted, increment to the solder.
Spoiled capacitors are slightly inflated. The top line of the cylinder contains a shallow slot when the product breaks, the sidewall is inflated, rejecting outward. Such a condenser replace first of all by finding a characteristic defect.
The burned resistors darken. Some retain performance, it is desirable to replace such a radio element.
Some hair dryers are equipped with self-regulation. The effect is achieved by using a resistive divider, with one shoulder of which is the element reacting to the temperature. Further actions are defined by the scheme for implementing the control of the parameter. We recommend:
The chance of failure is great if the device is trained to respond only to a fixed resistance value. It remains searching principal scheme On the Internet or draw yourself.
The repair of professional hairs are greater complexity. The design elements are often complemented by smooth regulators and additional options like the CARE button. The spirals are made of special alloys, creating negative ions when heated, having beneficially affecting the hair. The technique remains the same:
Before repairing it is desirable to get a fundamental scheme.
Industrial models are not much different from domestic ones. But dry hair is not recommended. Such products are distinguished by increased resistance to dust, shocks, vibrations, humidity, other climatic factors. Home restoration of industrial hairdryers will end in the best way.
Electrojudio content used in household models are not suitable for exploitation. Requirements are presented to wires, power cord, motor and spirals.
The repair of household appliances sometimes costs "a penny", so many are ready to engage in independent study of this topic in order to save the funds of the family budget. Yes, and quality with a competent approach will be guaranteed.
Despite the seeming difficulty, repair the household hair dryer without the help of professionals is quite possible. It is necessary to arma the theoretical knowledge of the internal device of the device and the necessary tools.
The device by which weighing hair and make laying is simple.
The housing is 2 plastic containers bonded with each other with screws. In individual models, instead of such fasteners use special latch brackets. The cunning lies in the fact that such elements do not carry practical benefits and are most often conditional fastening. The fan is one of the main components of the elements.
The function is:
The electric motor is a low-voltage collector motor based on a single diode (as in Scarlett) or in more expensive models (such as Remington or Babyliss) - a diode bridge that provides the straightening of the voltage, and attached to the motor contacts in the form of a mounted mount. With the help of the capacitor, it is coordinated by the batteries, or this is coping with inductive spiral.
It happens that when trying to turn on the hairdryer, the device does not start work and the engine does not start. Or after the short work, the hair dryer turns off.
Fault options here are several:
Most often, when the hair dryer stopped turned on or completely broke, such external changes occur in the work of the device, as the appearance of the smell of Gary. The reason may be that in the process of drying hair, their particles were stuck in the grid of the hair dryer and wound on the heating element. Either the situation is somewhat more complicated - the microcircuit wire burned down.
It is possible to reduce the quality of drying. The hair dryer begins weakly blow and overheats in case of critical filter contamination on the back of the device.
If they break, then the power of revolutions will decrease. It is possible to reduce the speed of rotation of the fan blades. The reason is most often in the ingestion of the siene of the foreign body. If the hairdryer works only in cold air mode and does not heat up, here you can talk about such damage, like blocking the "Culle" button or brave of spiral, damage to the chip or thermostat failure.
To begin searching for the reason for the faulty performance of the hair dryer, it is only necessary to stock up with 2 things, the first of which is the instruction to the device, and the second is a sacral impeller and a flat screwdriver. Getting Started, you need to remember that the device must be disconnected from the power supply.
The order of disassembly of the hair dryer (type Remington D3700 or Maestro) includes:
Next is the inspection of the electric motor for faults. If there is a breakdown in the motor, it will be markedly in color and appearance Contacts. Extract in this case is not required. If the engine burned down completely, then here it is already talking about the boar of the hair dryer and replacing the motor.
Getting started to repair a household hair dryer, should be considered constructive features The specific model and the specifics of all its elements. Standard order of repair of such an appliance (suitable for all bosch models, Braun, as well as Vitek, Babiis and Brilliantcare with the ionizer) is to comply with the stages.
First of all, it is necessary to clean the fan blades and the surface of the motor from the accumulated hair coma:
It is important to remember the inadmissibility of the wet processing of a hairpack of a hair dryer, because after that the contacts will stop working. Next, we carefully clean the spiral and filters, in the case of overheating and the presence of the smell of Gary. To troubleshoot the hair dryer (or if it is turned off), inspect the cord on the subject of the interrupted wiring, especially at the base of the device.
To this end, special testers or indicator screwdrivers are used by connecting to the network.
It is not recommended to repair in this case, it is better to replace the cord on a new one. Since the likelihood of moisture from entering the place of insulation and closing the device is great. If the breakdown is not detected, you need to open and inspect the heating element and its contacts. In the case when the last moved from the scheme, you need to use the soldering iron. We also pay attention to how the position switch began to work. If it found a nagar, eliminating such using emery. In the case of contacts (when the hair dryer does not turn on) - soldering. If the repair items are not subject to - replace them with new ones.
The specificity of the device is such that in some models (for example, Brown or Bosch) there is a function of selecting the speed of air flow and the intensity of heating, and others have only separate regulators of the rotational pace or degree of heating (in low-cost Vitek or Scarlett models). The number of plastic blades is also different - there may be 2-3 and (as in the industrial sample hair dryers) even 4. The heater consists of parts such as a spiral from a non-nichrome and a heat-resistant base under it. The hairdryer begins to heat up precisely at the expense of the spiral. The number of windings in the spiral affects the number of switches modes.
Visually disassembly schemes are as follows:
Thermal protection is represented as a customizable regulator and thermostat. The principle of operation of the latter is that, when an allowable temperature threshold is exceeded, the terminals of such an element begin to disperse, and the chain is broken. When the hair dryer cools, the terminals are connected again, and you can dry the hair again. Another border on the path of hot air is a special fuse. In the case of his triggering, such an element will need to be changed. Also on the outer panel of many hairdryers there is a button, thanks to which the device blows with cold air. This feature not only allows you to maintain hair health, but also stops the process of heating the spiral.
As a rule, for the operation of a household hair dryer, it is necessary to have a permanent electric cooker from 12-32 - 220V.
There are switches of modes and regulators. Depending on the manufacturer, the number of speeds and the presence of additional options will be varied. Electroscheme allows you to establish the relationship between all the elements of the device.
Why first there is an inspection of the fan and its blades - as it continues to work badly after cleansing from the hair, and involves the search for admired parts in order to replace them. Also inside the shaft there may be all possible small parts, pulled by a hairdryer in the process of non-accurate handling of the device.
The repair of the heating element involves the elimination of the spiral breaks by twisting the wire, the use of the soldering iron or the method of tinning.
In the event of the engine breakdown, intensive crackling will be coming out of the hair dryer and even depart the sparks in the blades area. Then you need to drop windings from the chip and reinpends with a triplex. But it is best to contact the workshop in this case, it is not so expensive (for example, the disassembly of Fenilips in Moscow will cost only 4 cu). If everything is in order with the windings, pay attention to the brushes and whether they are sufficiently adjacent to each other. In addition, it is best to lubricate the running parts and check the degree of their condition with manual rotation.
The following review represents the process of dismantling the hairdresses of the Roven (including the Beauty and YFA 223J models) and includes:
When cracking the chip, you need to clean it and solder. Next is the inspection of condensers and replacing them to new in case of bloating. If resistor parts have darkened, such a state indicates the burnout of the elements. It is also required to replace defective spare parts.
If necessary, it is necessary to independently repair a professional (such as COIFIN classic or in the shape of a forcepets, as well as electrophen with a margin of Pro) or a construction hairdryer (for example, an intercol EF 2000), it can be easily useful to the proposed scheme, since such devices have a device similar to everyday Fenes.
Hair dryer hair dryer is electrical appliancerepresenting a cut of a pipe through which high speed A stream of air heated to 60 ° C is supplied at a given direction. Often, for ease of use, the pipe is equipped with a pistol handle.
The photo shows the Melissa Magic brand with a capacity of 1600 W. The handle placed a switch of modes of operation, with which you can turn on the hair dryer and stepwise change the temperature of the outgoing air nozzle.
The construction hairdryer in appearance, the principle of operation, the device and the electrical circuit is practically no different from the hair dryer. Only in it the air flow is heated to 600 ° C.
When the hairdryer is turned on, then cold air out of the room is suused in its pipe using a rotating impeller struck on the motor shaft direct current. Next, the air flow passes through a tetrahedral heat-resistant frame from mica or ceramics, which is wound to warm spiral from nichrome. Cooling the helix, the air flow is heated to a temperature of 60 ° C, and in a construction to 600 ° C, after which it comes out of the pipe.
On the body of the hair dryer, there is usually a switch combined with a stepped setting of the mode of operation, allowing you to turn on the hair dryer to a complete or half-power mode.
The photo shows the appearance of the typical engine switch mode switch.
To eliminate the skin burn when drying the hair and destruction of the body of the hair dryer when the engine is disrupted, it is installed on the frame heavy protection in the form of a bimetallic plate.
When the air is heated above the specified temperature, the bimetallic plate bends up the arrow in the drawing and opens the contacts. The heating spiral is de-energized, and air heating stops. After cooling, the bimetallic plate is returned to its original position, and the contacts are re-closed.
As can be seen, the principle of operation and the device of the hair dryer is not much different from other heating household appliances and to repair the hairdryer can any domestic master.
Most construction hairdels and drying hair have below the electrical circuit. The supply voltage is supplied through a C6 type fork with a flexible cord. The C1 condenser serves to suppress the interference emitting the brush node of the engine. The R1 resistor serves to discharge the C1 capacitor after disconnecting the plug from the socket to eliminate the shock of the human current when the plug is touched. In some models, the elements C1 and R1 are not installed.
Managing the performance of the hair dryer is performed using the S1 switch. In its position shown in the diagram, the hair dryer is in the off state.
When moving the switch motor to one step to the right, its movable contact closes the conclusions 1-2 and the supply voltage through the rectifier diode VD1 enters through the current-limiting helix H1 on the engine and the heating helix H2. The diode cuts half sinusoids and thus reduces the speed of rotation of the impeller, and the heating power of the helix H2 half.
When moving the engine is still one step, contacts 1-2-3 are closed, all the voltage of the network is supplied to the heating element and the engine and the hair dryer works at full power.
Usually, DC motors, calculated on the supply voltage of 9-12 V, are installed in the phenomena, the helix H1 is used to reduce the voltage. To convert an AC to the constant, the diode bridge VD2-VD5 serves. Electrolytic capacitor C4 smoothes ripples. C2-C3 sparkling capacitors perform the task of the sparks in the brush collector assembly of the engine and the suppression of radio interference.
The S2 button is used to switch the performance of the hair dryer to the cool air mode. When you click on it, the helix H2 stops warm.
To protect the hair dryer from overheating, which can occur due to reducing the inclination of the impeller in the event of a motor malfunction, serves the hermal protection element ST, which opens the supply voltage supply circuit to the heater H2 when the maximum allowable air flow temperature is exceeded.
Attention! In the repair of the electric hairdryer, caution should be taken. Touching bare parts of the circuit connected to electrical network It may lead to electric shock. Do not forget to remove the plug of the hair dryer from the outlet!
If a broken hairdryer got into repair, then first of all it is necessary to find out for what external signs of the hair dryer was recognized as defective. By them, using the table below, immediately assume in which place to seek a malfunction.
| External manifestation, reasons and ways to troubleshoot fane | ||
|---|---|---|
| External manifestation | Probable reason | Remedy |
| When drying hair, the hair dryer is periodically disconnected | Passing the power cord at the exit place from the body of the hair dryer or fork | Repair or replace network cord or plug |

Disassemble the hairdryer is more difficult than repaired, since parts of the body are usually connected inside with the help of latches, the location of which is not visible from the outside.
But always on the handle in the field of entry into the housing of the network cord, there is a self-tapping screw, usually closed with a decorative plug or a stabbed label. Thanks different color Parts of the BRAUN hair dryer, shown in the photo, can be seen from what line to disassemble it.
This is what the decorative plastic plug looks like in the body of the hair dryer. Since it is one color with a handle, it is difficult to notice it. To remove the plug, you need to be a sharp object, for example, a seboard or a knife with a sharp end of the blade to pry it over the edge.
After removing the plug, the screw head became visible, but it turned out that the slot on it is triangular, and the face is made in such a way that the self-tapping screw can be screwed only clockwise. The manufacturer provided that at home the hairdryer for repairing to disassemble without breakdowns the case was impossible.
To unscrew the screw with such a head, first with the help of a heated electric soldering iron, it was heated. To do this, just press the sting of the soldering iron to the head and hold for a couple of minutes. From the heating of the plastic self-reserves around the thread softened. Next, while the plastic has not cooled, with a screwdriver with a flat stale width equal to the length of the verge of a triangle of the Slice Selflessness without difficulties was unscrewed.
In order to avoid difficulties in the need for a hair dryer, the solemnosis was replaced with the same size, but with a slot in the head under the crusade.
The removable part of the housing was additionally held on four latches. Two of them were on the sides of the pipe. To disassemble, it was necessary to squeeze them through the resulting slot using a flat screwdriver simultaneously with the dilution.
After the discharge of the side latches, the top was released themselves. The latches were shallow, so they managed to disassemble the hair dryer without breaking them.
In this box, the network cord was faulty, and therefore it was not necessary for its disassembly, since the cord connection site to the electrical circuit was affordable.
Most often, the hair dryers are broken due to the laptus of the network cord or disruption of the electric motor with the impeller. In modern hair dryers, due to the presence of thermal protection and use of thick wire for winding the spiral, it burns very rarely. From a dozen renovated by me, hairdresses with a distilled helix did not see.
When drying hair dryer, the hair dryer moves intensively and the power cord is constantly bent. Although the wires in the cord are copper and multi-core, but from the multiple gerbins over time are round. A sign of the beginning of the cliff of the wires is the periodic temporary termination of the hair dryer during drying hair.
Therefore, half of the breakdown is associated with the laptop of the network cord at the exit of the housing, less often at the plug. The first sign of such a breakdown is interruptions in the hair dryer during drying hair. At this stage it is easy to find out the place of the cord defect. It is enough to fix it in the middle and move the cord at first at the entrance to the body of the fork, and then at the entrance to the body of the hair dryer. If the hairdryer will work stably, it means that the cord is in order and the malfunction must be sought elsewhere.
If the wires in the cord rushed at the place of exit from the fork, then you can repair the hair dryer without disassembling it. About how to replace the plug is described in the article "Electric fork, how to connect, repair".
Usually, the cord wires inside the hair dryer are soldered to the printed circuit board or join with the help of the clad terminals, as on the photo above.
To check the cord, you need to ring the wires, touched by one probe of the tester or the multimeter to one of the plug pins. The second probe multimeter alternately touch the ends of the wires. One of the wires should show zero resistance. Between the remaining wire and the second pin should also be zero resistance.
If the wires are nicknamed, then the mechanical cord can be accurately determined at this time, in which place the wire is pulled. In the repaired product, the cord was torn off at the input site in a hairdryer.
If the cord wires are soldered to the printed circuit board, then they can not be squeezed, connecting the probe to the instrument to the plugs. The dryer switch must be set to maximum power mode. The heating spiral has a resistance of about 30 ohms. Therefore, if the cord wires are working, the multimeter should show the same resistance.
With the help of an online calculator, you can accurately calculate the resistance value of the nichrome spiral of the hair dryer, based on its maximum power.
In a repaired hairdryer, the cord break was at the injection site into the case. To restore work, you need a defective area of \u200b\u200bthe wires to cut off and remount the capel terminals. To remove the terminals from the wires, you first need to spend a knife to break up the mustache, fixing the wires, as shown in the photo.
In the next step, the looting section of the wire is cut off and insulation is removed from the cord and wires. The length of the cord will decrease on a tet of centimeters, which will not affect the performance characteristics.
It remains to start the wires and terminals with the help of a solder with an electric soldering iron and solder them together. After putting on the terminals, assembly and checking a hair dryer, repair can be considered complete.
If there is not at hand of the soldering iron, then in this case the wires are cut off at a distance of 3-5 cm. From the connection location to the electrical diagram of the hair dryer and the segment of the defective cord is removed. Then the wires are connected by one of the mechanical methods, depending on the inner free space in the handle of the hair dryer.
He fell into repair of a hair dryer Melissa-1600, with a complaint that the air flow from it became weak with the smell of Gary. When checking it turned out that the impeller rotated with insufficient speed. Immediately suggested that the hair between the impeller and the body was hung. Usually in most cases, with such signs, this happens.
But after dismantling the hair dryer, it turned out that one of the rectifier diodes installed on the engine was ripped in half. The sound of the rest of the diodes showed their serviceability. Therefore, the engine and worked, but only one half-wave of straightened voltage was served on it.
The faulty diode was falling and in its place, with the observance of polarity, the first-type KD105 type was smeared. The engine power supply is usually 9-12 V at a current of not more than 0.5 A. Such parameters will provide almost any rectifier diode.
At the same time with the shaft of the motor, woven hair were removed and the bearings were smeared with machine oil. To do this, it is enough to apply a drop of oil to the point of fixing the shaft in the motor housing and turn several times the shaft for the impeller.
Before installing the engine in a hairdryer, it is desirable to check it. For motor operation, a constant voltage of 9-12 V. is required, but since the voltage is fed to the diode bridge, you can save the engine from both the constant and alternating current source. Even the simplest adapter from any device, outstanding the corresponding voltage and current to 0.5 A.
It is necessary to feed the voltage to the inlet of the diode bridge, the points of its solder to the electrical diagram of the hair dryer. If the engine connects to a constant voltage source, then you need to check first at one polarity of the connection, and then change the connected wires by places. It is necessary to check all the diodes of the bridge.
The engine tests after prevention and repair showed that its impeller when scrolling the hand rotated easily and when the voltage is supplied from an external voltage source with sufficient speed.
Checking the hair dryer after assembly showed that it is fully restored. The impeller rotated at high speed, and the smell of Gary disappeared.
If the hairdryer cannot be enabled, and the network cord is working, the reason, as a rule, is a violation of contacts in the modes switch. And if all the dimensions of the hair dryer, but the air does not heat up, then the heating, heat shut off or burned, is faulty.
Switches of operating modes in the hairdryer are usually soldered into a small pCBwhich is fixed in the guides or fastened with self-draws. The photo shows the conclusions of the switch, charged in the printed circuit board. On the left side, the hot air feed switch is visible.
If the mode switch is not called, you can try to try to clean the internal contacts through the hole located next to its engine. It happens that only the contact of one of the modes of operation burned down, and the rest in working condition. In this case, you can sacrifice the rarely used feature of the hair dryer and switch the switch to a good contact.
It happens that due to the burnt contacts as a result of heating, the case of the switch is deformed and the engine is jammed. In the absence of a switch on the replacement, you can connect the wires directly by leaving only one hair dryer mode. In this case, the hair dryer will have to connect its plug to the outlet.
If the off button of the turning off of the warm air flow is faulty, and it has nothing to replace it, then it is enough to root its conclusions. In this case, this feature will not work anymore, and the rest of the hair dryer will work, as before.
Thermal protection is two contact contacts, one of which is fixed on the bimetallic plate. When the plate is heated above the desired temperature, it bends upwards, as the arrow shows on the photo. As a result, contacts are blocked, and the power supply circuit of the heating spiral is broken.
If the shutdown button of hot air is fine and the spiral is a whole, it is obvious that contacts in the thermal protection relay were oxidized. To restore, it is enough in the gap between the contacts to introduce a folded twice-grained sandpaper and pressing the bimetallic plate from the top of the finger several times to stretch the paper.
If the air flow from the hair dryer is cold when the engine running, a good shutdown button and thermal protection, then the breakage is associated with the nichrome spiral.
The spiral break is easy to detect an external inspection. A contact disorder in compounds in the form of hollow rivets on the frame of the hair dryer of the ends of the nichrome wire with wires, running from the operating mode switch, can not be determined in appearance. If rivets do not have spontaneity, then only a multimeter sounder will help.
To restore contact in the rivet connection, it is necessary using the pliers to additionally enable it. Work should be done carefully, so as not to break the fragile mica or ceramic frame.
Blizzard or broken spiral in modern hair dryers is practically not happening, but if such a refusal happened, the helix will need to replace the new one. The splicing of wire spirals with a twist or compression in the segment of an aluminum or brass tube will not lead to long-term success. If the spiral was worn out, then after such a repair, it will soon overrigent in another place.
Nichrome spiral, taking into account the power of the hair dryer, you can purchase a new or co over from your nichrome wire, calculating its diameter and length on the table.
Another common malfunction of the hair dryer, which can be eliminated independently, having only a standard tool set at hand, it's when the hairdryer works, but the outgoing air jet is very hot with the smell of Gary from behind the winding on the hair engine tree or poor engine bearings.
I got to repair the Babyliss hairdryer, shown in the photo, with a complaint that the outgoing jet of air became weak and very hot.
When checking, for the sound of the fan, it became clear that the frequency of its revolutions is underestimated, and the cause of the malfunction lies in the engine operation. To eliminate the fault, the hair dryer had to disassemble.
In order to disassemble the Babyliss hairdryer, you first need to remove the nozzle by unscrewing two screws. Next, with a screwdriver with a flat sting, a locking ring is removed from the output side of the heated air. It can be easily.
It remains to disconnect the halves of the case, which are held on two latches from each side. In the photo, due to the translucentness of plastic, the latches are clearly visible, as in the photo in the form of light strips.
The hairdryer was disassembled and left to get to the place of the shaft, where the hair was wound. The engine is fixed inside the plastic housing, which is a pipe in such a way that it is necessary to remove the fan impeller to remove it. And the impeller, as a rule, is attached to the shaft tightly and here usually there are great difficulties, because it is impossible for the impeller with a standard tool, and it is easy to break it easily.
To solve such tasks, I have made from Chinese wall-building Special tool - light-bottomed at the right angle ends of the sponges. With the help of the tisces, the ends easily bent, because they were not hardened.
With this climb, I also successfully repair the slots of the serpent and lightning, in case the links cease to be closed. Ordinary pliers often do not get there. And thanks to the curved ends of the sponges in any cases, it is easy to squeeze the closing links part of the slider.
In addition to the upgraded pliers-water-in-room, it is convenient to hold the axles and shafts, nuts and other items of different forms - do not slide, like a pliers with flat sponges.
After removal from the shaft of the engine, the impeller has access to the winding hair. In this model, a hair dryer puts a brass sleeve on the engine shaft, and the impeller is hoping. It is usually planted directly on the engine shaft.
It remains only to a sharp object, such as a knife, seer or needle, remove hair and collect a hairdryer in the reverse order. So that it does not have difficulty assembling a hair dryer, while disassembling I advise you to make some photos.
At the Viconte Hair dryer, the external manifestation of a malfunction was the same as in Babyliss, but in addition the air proceeded to the smell of Gary and the fan worked with a spray. This testified that the engine bearings were produced.
The sequence and technology of disassembling a hair dryer is similar as a Babyliss hair dryer, so it is not necessary to describe it.
The supply voltage using two wires was fed to the diode bridge, sprinkled on the engine outputs. For the convenience of repairing the wires were squeezed with a soldering iron. The colors of the wires can not be memorized, since alternating voltage is fed to the bridge, and the values \u200b\u200bof the wire connection is not.
An attempt to remove the impeller from the engine shaft using the above-described walls was not crowned with success, even with a large muscular power. I had to invent, how to remove your hair and lubricate the bearing, without removing the impeller.
The idea came that you can not suffer with removing the impeller, and drill a hole in the engine holder housing, which was done.
The location of the hole must be measured, not to get into the engine body or the base of the impeller. At first, a hole with a diameter of three millimeters was drilled, and then twisted to five. Plastic housing is soft and thin, so the hole can be made and the end of a pointed knife.
To remove hair from the engine shaft from the stationery clips, a hook was made. To make such a tool, you need to bend the end of the clips, on the sandpaper it to sharpen it and the tip of two millimeters long. During the minute, all the hair was removed.
For lubrication of the bearing had to take advantage of the medical syringe. It is enough to apply one drop of the oil to the engine of the shaft into the engine. In order for the oil to fall into the bearing, you need to take the impeller, move the shaft several times along the axis, scrolling it.
It is necessary to smear the bearing on the opposite side of the shaft. Any machinery is suitable for lubrication, for example, to fill in the car engine. If there is no oil at hand, then you can remove the inconscepiece of the oil level from the engine from which to take some dripping drops.
To test the fan operation, a voltage of 10 V from the DC power supply was supplied to the diode bridge. The engine will work at voltage from 5 to 12 V, so even the charger is suitable from any phone. This check is not necessary, but if possible, it is better to make sure that the fan earned as it should be.
The check showed the normal operation of the engine, without outsiders and sufficient air flow head. You can not close the hole and not close, as it fits tightly to the body of the hair dryer. If not so, then you can take it with scotch.
As you can see, the most common breakdowns of the hair dryer eliminate at all difficult and such a job forces if you wish anyone homemade Master. In any case, it is before buying a new hair dryer to try to repair the failed hairdryer.
With the modern rhythm of life, it is important that it was possible to quickly lay the hair and make a beautiful hairstyle. For this purpose, a household electric hairdryer, which must be chosen correctly to keep the health, beauty and strength of your hair. This device dries our hair for more than 75 years, its first model appeared in the 40s of the last century.
In order for this device to meet all the necessary requirements and worked for a long time, the acquisition should be paid to its technical parameters, as well as structural features.
Today, the household hairdryer is available in every home, especially if there is a woman in the house. But internal organization This device, and what principle it works, is not familiar to everyone. Therefore, it will not be superfluous to consider this question more.
The device of the hair dryer is quite simple. In the housing made of durable plastic, there is a fan, an electric motor and a heating element.
The principle of operation also does not cause difficulties in understanding: the air flow comes from the back of the housing under the action of the fan, then passing through the heating element, the air heats up and leaves the hair dryer through a narrow nozzle.
For dryshka long hair Designed special nozzles that wear nozzle, for example, a round brush or comb. There are other nozzles in the form of large and small comb of different versions. From the end of the hair dryer, where air enters, the lattice is installed to protect against the housing of long hair and various items.
Different modifications of the hair dryers can additionally have regulators installed on the handle designed to adjust air velocity and its temperature. Typical schemes Household hairdryers are almost the same, except for some features.
The fan consists of a collector miniature electric motor that can operate from voltage 12-18 volts.
A plastic propeller is installed on the shaft of this motor, the shape of which may differ, depending on the brand and manufacturer.
The heating element consists of a heat-resistant base on which the nichrome spiral is wound. Such spirals can be somewhat, depending on the number of operating modes.
During the work of the hair dryer, the spiral should continuously blow up air, and heated it. If the fan has failed, and the spiral continues to heat up, it should work protection against overheating in the form of a thermal. Currently all modern models equipped with such protection, in contrast to old versions.
The main task of the electric hairdryer is drying and hair styling, if we consider the household model. The air temperature sometimes reaches 60 degrees. For protection against damage to the internal elements of the hair dryer due to high temperatures The design of the main models is equipped with special protection.
The trading network presents big choice household and technical hairdryers various destination, technical parameters and design. In order not to get lost when choosing and be able to correctly evaluate all the advantages of the product, you should familiarize yourself in advance with all the features and types of models.
He has a big list functionality. The scope of its use is so wide that it is difficult to overestimate its importance in the production of construction work. This tool is used for work in which local heating is required, for example:
- Drying hard to reach places;
- Engine warming in winter time;
- drying glue;
- Delete old paint. from the surface;
- Outline of the tree;
- Welding outdoor coating;
- softening of linoleum, plastic;
- gluing synthetic films, plastic products, pipes.
Sometimes the building electric hairdryer replaces the soldering lamp. At the same time, its advantages are the absence of open fire, combustible materials, the power and air temperature can be adjusted.
If we consider all the nozzles for styling, there are a large number of them, for example:
- Round nozzle with twisters for long hair.
- Round brush to create volume.
- semicircular brush to give the scope of roots and leveling strands.
- Comb for creating volume and hair straightening, creating different species stacking.
- a rotating brush for curling and combing strands, giving them volume.
The right choice of this domestic helper will allow you to create beautiful hairstyles, care for hair and create a unique style.
First you need to determine the aim of which you want to purchase a hairdryer. If you need it for drying hair, then you need to choose reliable design With the smallest number of functions. If the hair dryer is required to use it in travel and trips, it is better to purchase a specialized road model. And if you like to often create beautiful hairstyles at home, then you will need a device with a large list of nozzles, high power and settings for different temperature modes.
When choosing, you should pay attention to the shape of the hair dryer. There is an ordinary electric hairdryer, and in the form of a brush. The usual model has a handle located with a slope to the housing. It is not always convenient for household useAnd it is necessary to get used to it.
Hairdryer is more suitable for those who master hair styling at home. By weight, such a model is easier to make your hand not to get tired. The case has a cylinder form, allows you to give aircraft different areas, It is used for laying hair using different nozzles.
Many consultants in stores, helping to choose an electric hairdryer, advise to watch only power, and say that the more this parameter, the device is better. But this is an erroneous approach, and talks about the incompetence of the consultant. Only the temperature of the emerging air depends on the power, and the drying speed of the hair.
There are models with a capacity of 0.2 to 2 kilowatt, while not always an increase in power affects the price of the device. You should not purchase the most powerful hair dryers, if the speed of hair drying is not important for you, but only a hairstyle look. When applying a very powerful hair dryer on the head there will be a complete mess, and you will not have time to do.
The number of speeds and temperature levels are also important when choosing an electric hairdryer. Using several modes, you can configure the necessary air pressure and change the temperature in the specified limits. The more modes have an electric hairdryer, the greater the number of combinations of settings can be made for styling and drying hair, as well as for creativity in the hairdresser's art.
The mode of operation of the hair dryers is very heavy. They are left on the floor in the bathroom, they have to fall from toilet tables, and in the process normal work They are constantly moving and shaking. Therefore, it is not surprising that the fabrics have to pay attention to frequently. For the sake of safety, each time before the use of this device, it is at least externally to make sure of its body and cord.

The body of the hair dryer is usually either divided into two "mirror" halves, or the front part is separated from the rear. Before disassembling the case, be sure to remove the plug out of the outlet.
Fig. 2.Disassembly of the fane
Your hair dryer may look different from the example shown here, but the principle of work is the same for all manual electrical hairdryers. The fan, driven by the electric motor, retracts the air through the air intake with the grille and drives it through the heating element - the wire wound on the heat-resistant holder. Some models are equipped with a removable filter that does not miss the hair and similar veins inside the housing through the air intake.
Fig. 3.Device of a fane
Many hairdryers have combined switches that do not just turn on and turn off the device, but also allow you to use two or three thermal modes. Some hair dryers have a cold blowing mode when the heater is disabled and only the fan works.
Thermostat - Here is meant the thermal protection switch - protects the heating element from overheating. The switch automatically shuts off the heating element if the air flow through it is too small to successfully select the heat from the element. The thermal protection switch is turned on again, as a rule, on its own, so it should be found out that it made it work before renewing the use of a hair dryer - after cooling it is usually starting to work as if nothing has happened. Since such a "recovery" can leave a hairdryer in a dangerous state, later models can be equipped with fuses that will not allow the device to turn on even after its cooling.
Bowls of the housing are always connected using recessed screws. For some of them, or for everyone, special screwdrivers may be required or modified flat screwdrivers. If the screws have different lengths, then marry them to facilitate the subsequent assembly. If, after unscrewing screws, the case is not divided easily into two cups, look for hidden clauses. Perhaps you will have to gently squeeze the edges of the case to see if its parts are distinguished at the same time with the housing plastic latches- But act Caution so that the body does not break and cracked, which will make the device unsafe in operation.
After driving the fastening screws, put the hair dryer on the table and gently divide the parts of the body so that you can remember the location of the internal parts and how they are included in the housing. If necessary, draw a scheme. As with all electrical appliances in double insulation, it is important before assembling to return all the elements, including wires, in their original state.
Before switching the thermal protection, turn off the hairdryer, the breath may appear. If the smell remains after the procedures described below, refer to the instrument check in the service center.
When using the hairdryer, keep it the handle so as not to prevent air movement if the hand is close to the air intake.

Regularly examine the cord to detect insulation damage. Carefully check the lack of breaks in the cord entry places in the plug into the body of the hair dryer. Damaged cord shorten or replace.
Fig. five Wear a hairdryer for the cord - a bad habit.
The barrier in the air intake may not be visible outside, so remove the plug of the hair dryer out of the outlet and disassemble the device to remove the hair, the fluff, etc., eliminate the air intake and the fluff with a soft brush.
If your hair dryer has a removable filter, unscrew the rear section of the case, remove the filter and the soft brush to clean the dust gathered. Be careful - do not damage the thin filter.

Check if the fan rotates freely. If not, remove the fan and delete what interferes. Make sure the intra-power electromotive is the integer, including heat-resistant insulation - and assemble the device.

Dust and downs that are tightened into the air intake can stick to the heating element. Wear it very carefully with a soft brush, trying to choose dust from the holes without excessive effort.
The fan rotates, but only cold air goes.
Check if air heating is enabled.
After feeding the plug from the outlet, inspect the wires to make sure the heating element is connected. If the soldering connections are broken, let the specialist restore them - they must withstand the current and temperature in the device.
Visual inspection can set a break in the spiral heating element. If it seems to be able to check and replace it with a specialist - but buying a new hair dryer can be economically more expedient.
Fig. eleven Inspect the heating element to detect the cliff
If there is access to the thermal protection switch or fuse (usually they are located within the heating element), then you can check them on the tester. These details are cheap enough. However, in some models, the thermal protection switch or fuse change only with the heating element, which may be economically inexpedient.
Fig. 12 Touch the two ends of the thermal protection switch
In this case, the smell of Gary may be present, since the fan does not create a sufficient air flow.
Check if the fan was wound on the shaft, which can slow down its rotation. Before removing the fan, mark its position on the shaft to return it to the same position.
If something interferes with the fan, it is sometimes difficult to remove it. This can usually be done, carefully uploading it to the shaft with a rod screwdriver, like a lever - but be careful, do not damage the fan itself and other parts of the hair dryer, which can do the operation of the device unsafe.
Remove all hair wrapped on the tree behind the fan.
Fig. 13
Put the fan and make sure it rotates freely.
Check out the disadvantage of the entire internal electromotion and the fact that all parts are delivered to their original position, then collect the body.
Check that the plug and cord is correct and replace the blown fuse. If the fuse begins again when the plug is turned on into the outlet and turn on the instrument, repair the hair dryer at a specialist.
If other electrical appliances stopped in the circuit, inspect the shield: it is possible that the fuse has blocked or worked the machine.
This is a common malfunction. It makes sense to check the condition of the external insulation of the cord every time before turning on the hair dryer, making sure that the cord is securely fixed with the pressure plate inside the plug. To check the cord to open it. If possible, replace the damaged cord.
Fig. fourteen Replace damaged cord
Soldering connections Let it be repaired by a specialist.
Check out the internal wiring: there is no weak or disturbed contacts. If soldering connections require repair, take the hair dryer in the workshop.
The switch can be checked with a tester, but if the wires are soldered to the switch, then the hairdryer should be repaired from a specialist, which can do very expensive.
A faulty electric motor must be checked by a specialist, but its repair or replacement can be economically inexpedient.
Good luck in repair!
