Principle of operation

The principle of operation of an ordinary hair dryer is based on a low-voltage commutator motor that runs on direct current:

• In order for the device to be able to turn on, a special lowering spiral is used in the design, which contributes to the voltage drop to the desired level. It is installed inside the heater.
• Using a diode bridge, the voltage in the hairdryer is rectified. On the engine there is a metal shaft on which the fan is mounted. The fan can be constructed of two, three or four blades.
• TEN of the electric hair dryer is made in the form of a spiral with a nichrome thread. It is wound on a fireproof base, which increases safety during use of the device. When connected to the network, the nichrome spiral starts to heat up, and the fan that is installed on it blows warm air directly from the hairdryer body.
• In order to protect the hair dryer from overheating, a temperature controller is used (it is set during operation), as well as a thermostat.
• In addition, the function of “cold wind” is installed in each hair dryer - when it is pressed, the spiral stops heating, only the engine and fan remain working, which is why cool air blows from the nozzle.

Important! It should be noted that not all models of equipment have a thermostat. It is intended to control the heating of the unit together with nichrome during the long operation of the device. For example, they can be a stationary professional hairdryer, which is used in hairdressing salons. When the coil heats up to maximum temperature, the thermostat turns off the power. After the spiral cools down, the contacts turn on again.

• At the same time, you can also remove the top panel cover, under which the fan is located. Most often, it is simply pressed to the case itself, so it gets without problems if you pry it with a flat screwdriver.
• Under the upper panel of the case there is a mode switch, a cold air button. Also on the panel there are several wires that are needed to connect to the contacts of the circuit. To continue disassembling, they will need to be removed.
• Now you can get the spiral from the hairdryer’s head itself. It is necessary to act extremely carefully, otherwise - it can break.

Important! Get out only after you are sure that you have removed absolutely all the fasteners.

Repairs

• If the hairdryer does not turn on, then immediately check the power cable. As a rule, it breaks off at the very base, because in the process of using the hair dryer many times rotates in various directions along its axes. If everything is normal with the wire, then check the contacts on the spiral itself. They may well be 2, 3, or even 4. When the device hits or falls, they sometimes become unsoldered, as a result of which the power supply to the engine stops.

Of course, their performance does not change too much, but if nicks or cracks are noticed, it is better to immediately replace the propeller. After the propeller, inspect the shaft. It happens that small parts or other debris that block the shaft fall into the hair dryer nozzle, as a result of which it begins to rotate slowly.
