Hereinafter, the effect of the hair dryer configured as described above will be described.

First, when the power switch 6 attached to the lower left end of the hair dryer main body 1 is turned on and the user selects a desired driving signal (wind speed and wind temperature) by the driving selecting means 20, the driving selecting means. Input from the input terminal 11 of the operation signal control means 30 from (20).

At this time, the control means 30 initializes the hair dryer according to the selected operation control function and simultaneously displays the operating state of the hair dryer through the display means 80.

In the rectifying means 10, the AC component and the high frequency component included in the commercial AC power supply from the AC power input terminal 9 are limited through the choke coil L1, and the voltage component of the commercial AC power supply is divided into voltage dividing resistors ( The partial pressure is limited through R1 and R2).

Accordingly, the zero suppression detection unit 12 half-wave rectifies the signal divided by the voltage dividing resistors R1 and R2 in the diode D2 so that only the divided signal in the positive direction is turned on from the rectifying means 20 while the transistor TR1 is turned on. The constant voltage signal Vcc is applied to the ground terminal through the resistor R3 and the transistor TR1, so that a low level voltage signal is applied to the input terminal 12 of the control means 30.

Accordingly, the control means 30 receives the zero suppression detection signal from the zero suppression detection unit 12 and outputs a low level control signal during the time period through the motor driving means 40 and the heater through the output terminals 01 and 02. Output to the drive means 50.

Accordingly, the motor driving means 40 receives a low level control signal output from the control means 30 from the light emitting diode LED1 of the thyristor 42 and emits light while the light emitting diode LED1 emits light. Triac PT1 is turned on.

Accordingly, the turn-on signal of the phototriac PT1 is applied to the gate terminal of the triac TRIAC1 through the resistor R5 to turn on the triac TRIAC1.

At this time, in the bridge rectifier 43, the heater 51 by the AC power input terminal 9 receives the AC voltage through the power component limiting heat loss resistance (R7) to protect the motor 41 by limiting the power phase. After rectifying, the noise component included in the full-wave rectified voltage signal is filtered through the coils L2 and L3 and the filtered signal is applied to the motor 41.

Accordingly, the motor 41 receives the control signal of the control means 30 in accordance with the operation signal selected by the user by the operation selection means 20 to drive the strong, medium, weak.

In addition, the heater driving means 50 receives the low level control signal output from the control means 30 from the light emitting diode LED2, and the light emitting diode LED12 emits the phototriac while the thyristor 52 receives the light. (PT2) is turned on.

Accordingly, the turn-on signal of the phototriac PT2 is applied to the gate terminal of the triac TRIAC2 through the resistor R8 to turn on the triac TRIAC2.

Therefore, the heater 51 receives the commercial power supply voltage from the AC power input terminal 9 and generates heat when the triac TRIAC2 is turned on.

Therefore, the air introduced by the blower fan 2 is converted into warm air by the heater 51 and discharged to this part through the discharge port 5, thereby setting the hair drying or the hair form.

At this time, the temperature detecting means 60 detects the heating temperature of the heater 51 and outputs it to the control means 30.

Accordingly, the control means 30 may generate ozone (O3) at the reference temperature Ts: the ozone generating means 70 in which the heating temperature T detected by the temperature sensing means 60 is preset. Maximum temperature, about 30 degrees).

As a result of the comparison, when the heating temperature T detected by the temperature sensing means 60 is greater than the preset reference temperature Ts, the ozone generating means 70 is output from the control means 30. The control signal is received through the output terminal O3 to prevent the ozone generating plate 3 from generating ozone (O3).

Since the ozone (O3) generation amount is chemically suppressed at a high temperature of the ozone (O3) and ozone (O3) cannot be generated properly, ozone (O3) is generated only when the temperature is below the reference temperature (Ts), that is, under cold air.

At this time, the display means 80 receives the control signal output from the control means 30 through the output terminal (O4), the heater 51 understands the ozone ( O3) is displayed.

When a predetermined time has elapsed, when the output of the heater 51 is continuously lowered and the heating temperature T is lowered, the temperature sensing means 60 detects this.

Accordingly, the control means 30 compares whether the heating temperature T detected by the temperature sensing means 60 is smaller than the preset reference temperature Ts.

As a result of the comparison, when the heating temperature T sensed by the temperature sensing means 60 is smaller than the preset reference temperature Ts, the ozone generating means 70 is output from the control means 30. Receives a control signal through the output terminal (O3) and outputs the ozone generation signal to the ozone generating discharge plate (3) to generate the ozone (O3) in the ozone generating discharge plate (3).

Therefore, the warm air is discharged through the discharge port 5 to dry the hair or to set the desired hair shape, and simultaneously generate ozone (O3) from the ozone generating discharge plate 3 to perform sterilization function in the hair. Keep your hair shiny.

At this time, the display means 80 receives the control signal output from the control means 30 through the output terminal (O4), ozone by the heat generating temperature (T) of the heater 51 and the ozone generating means (70) Indicates whether (O3) is generated.

According to the hair dryer according to the present invention, as described above, ozone is generated by ozone generating means when the hair is dried or blown by a blower fan to perform sterilizing function in the hair to prevent hair contamination and damage. Not only can it be prevented, it also has the excellent effect of keeping your hair clean and shiny at all times.
