Here, when the user grips the handle, the hair dryer may sense a touch of the hand through the first touch sensor 111 and the second touch sensor 112. In other words, the hair dryer may recognize that a human hand is touched when both the first touch sensor 111 and the second touch sensor 112 detect a touch.

The touch signals sensed by the first and second touch sensors 111 and 112 are transmitted to the voltage converter 101 of the controller to be described later.

The control unit 100 may include a voltage converter 101, a central processor 102, a strength and weakness control unit 103, and a main switch unit 104, and may optionally include a selection switch unit 105.

The voltage converter 101 receives a signal received from the sensor unit 110, and converts the voltage received from the sensor unit 110 into a predetermined voltage that can be recognized by the central processing unit 102. The voltage converted by the voltage converter 101 is transferred to the central processing unit 102.

In addition, the central processing unit 102 may receive the voltage from the voltage conversion unit 101 and drive the motor 130 and the heater 140 according to the voltage. That is, when the sensor unit 110 detects the touch of the hand, the central processing unit 102 may drive the motor unit 130 and the heater unit 140.

After the central processing unit 102 drives the motor unit 130 and the heater unit 140, and if a touch of a hand is not detected, the central processing unit 102 may stop the motor unit 130 and the heater unit 140 after a predetermined time. .

In addition, the hair dryer of the embodiment according to the present invention may optionally include a selection switch unit 105, which may provide a function to automatically or manually control the operation of the hair dryer by the user. In more detail, in the "automatic" mode of the selection switch unit, the driving of the hair dryer may be controlled according to the touch detection of the sensor, and in the "manual" mode, the user may control the driving of the hair dryer.

The motor unit 120 may turn the fan of the hair dryer by the voltage transmitted from the central processing unit 102 to generate wind.

The heater 130 may heat the wind generated by the motor 120 to allow hot wind to come out of the hair dryer.

Hereinafter, the operation method of the hair dryer which consists of such a structure is demonstrated.

First, the user can start driving the hair dryer by turning on the main switch unit 104. Here, the user may adjust the strength of the motor unit 120 and the heater unit 130 at any time through the strength control unit 103.

Subsequently, when the user grabs the handle, both the first touch sensor 111 and the second touch sensor 112 of the sensor unit 110 detect a touch and transmit a signal to the voltage converter 101.

Subsequently, the voltage changer 101 receives signals from the two touch sensors and outputs a voltage of about 0.5V or less for each of the central processing unit 102 to recognize the touch sensing.

Here, when the touch change is not detected by the two touch sensors, the voltage change unit 101 may output a voltage of about 4.5V or more.

Subsequently, the central processing unit 102 may control the driving of the motor unit 120 and the heater unit 130 by receiving a voltage to the voltage conversion unit 101. That is, when both touch sensors sense a touch, the central processing unit 102 drives the motor unit 120 and the heater unit 130 by a voltage of about 0.5V output from the voltage converting unit 101.

If even one of the two sensors does not detect a touch, the central processing unit 102 may stop the operation of the hair dryer. Here, the central processing unit 102 may be configured to immediately stop the operation or to stop after a predetermined time.

In addition, even after the central processing unit 102 stops the operation, when the touch is sensed by the sensor unit 110, the central processing unit 102 may drive the motor unit 120 and the heater unit 130 again.

On the other hand, the hair dryer according to an embodiment of the present invention may be selectively provided with a selection switch unit.

The selection switch unit 105 may provide a function that can be set manually or automatically by the user.

More specifically, the user can control the operation of the hair dryer by the above-described method when using the hair dryer automatically set, and when the user uses the hair dryer by manual setting, the user can directly turn on / off the switch. Drive can be controlled via In addition, the selection switch unit 105 can be used by excluding from the drive control device of the hair dryer.
