Description

Hair Dryer Using Infrared Ray Heater

The present invention relates to a hair dryer which is a kind of hairdressing device.

In general, a hair dryer (Hair Dryer) is an electric device that dries the moisture left in the hair after washing the hair. Hair dryers are widely used in homes and businesses because they heat air with a heating element installed therein and force it to be blown by a fan motor to dry human hair or other wet objects easily.

In the conventional hair dryer, as shown in FIG. 1, components that perform main functions such as heat generation and blowing are installed in the main body 4.

The main body 4 is formed with a handle 6 on one side for the user to grip the hair dryer. The handle 6 is provided with a control switch 8 that can be adjusted in steps such as stop, cold, weak, strong wind.

Inside the main body 4, the mica board 10 which crossed two sheets of mica board in + shape is provided. In the + -shaped mica board 10, the coil heater 12 is wound several times on the outer circumferential surface. The hot wire heater 12 is a heating element that generates heat by electricity supplied. In addition, a blowing fan 18 which rotates during the driving of the motor shaft 16 of the fan motor 14 is provided at the rear of the mica plate 10.

In addition, an air suction port 20 is formed in the main body 4 so that air is sucked in front of the blower fan 18. And the air outlet 22 is formed on the opposite side of the air inlet 20 so that the sucked air is discharged.

Such a hair dryer is used while operating the control switch 8 in a state of holding the handle (6) to adjust the stop, cold wind, weak wind, strong wind stage.

In the cold wind step, the hot wire heater 12 does not generate heat and operates only the fan motor 14 which rotates the blower fan 18.

In the mild wind stage, power is applied to the hot wire heater 12 to be heated, and the blower fan 18 rotates at a rotation speed adjusted by the fan motor 14 to supply warm air.

In addition, in the strong wind step, the blowing fan 18 is rotated at high speed by the fan motor 14, and the amount of heat generated by the hot wire heater 12 is also increased to supply strong warm air.

On the other hand, the outside air sucked through the air inlet 20 of the main body 4 by the rotation of the blower fan 18 passes through the hot wire heater 12 that generates heat while being guided by the + -shaped mica plate 10. . As a result, the outside air is heated to become warm air, and is discharged through the air discharge port 22 by the blowing fan 18.

In this way, the hot air discharged from the hair dryer dries the user's wet hair and the object to be dried.
