Hereinafter, the operation control of the digital hair beauty device according to the present invention will be briefly described with reference to the block diagram of FIG. 8.

First, the main PC 50 provided in the lower body 200 includes a heating plate controller 50a for switching external AC power transmitted to the heating element 41, a decompression circuit unit 50b for depressurizing an external power source, Feedback the switching operation of the heating plate control unit 50a according to the power supply unit 50c and the power supply unit 51c to stabilize the reduced power and deliver it to the MC oil, the operation of the power switch 51 and the set temperature of the temperature control unit 50e. It includes a control unit (MCU) 50d for controlling, and a main input / output unit 50f for outputting data on the temperature value set by the temperature controller 50e to the sub PC ratio 32.

At this time, the temperature set by the temperature controller 50e or the current temperature of the heating element 41 is visually displayed by the display unit 44 provided on one side of the lower body 200.

The external AC power is directly transmitted to the heating element 41 through a fuse, and a stable voltage (eg, for driving the MC oil 50d by the separate decompression circuit part 50b and the power supply part 50c). 5V), but the circuit content thereof is a conventionally known technique implemented by a resistor, a capacitor, and a regulator, and thus, a detailed description thereof will be omitted.

In addition, the MC oil 50d controls the switching operation of the heating plate controller 50a through pulse width modulation (PWM) according to the temperature set by the temperature controller 50e, and is transmitted to the heating element 41. An external power source is turned on / off, and the heating plate controller 50a can be easily implemented by photo active devices and transistors TR, FET, SCR, and TRIAC.

On the other hand, even if the upper body 100 and the lower body 200 is supplied with the same power due to its structural characteristics, the temperature generated in each of the heating elements 31, 41 may be different.

On the other hand, in the present invention, the heating element of the upper and lower bodies 100 and 200 through the temperature control unit 50e and the MC oil 50d of the main PC ratio 50 is basically the temperature selected from the temperature control knob 52 31) to control the power supply so that 41 generates heat to the same temperature.

However, since the necessity of controlling the heating elements 31 and 41 of the upper and lower bodies 100 and 200 to different temperatures may be generated according to the use environment and purpose, in the present invention, the mode of the sub PC ratio 32 It can be implemented to be selectable by the setting unit 32e.

That is, when the mode setting unit 32e operates, the heating element 41 of the lower body 200 generates heat at a first selected temperature, and the heating element 31 of the upper body 100 has a second selected temperature selected by a user. Will generate heat.

At this time, the mode setting unit 32e is a hardware method such as operating by moving the temperature control knob 52 to a specific position, or the temperature of each of the heating elements 31 and 41 in the MC oil (32d) (50d) The ratio may be preprogrammed and implemented by a software method of determining the respective temperatures by rotation of the thermostat knob 52.

The hardware method means, for example, determined by selecting the rotation direction of the temperature control knob 52, which is displayed separately on the display unit 44.

In addition, the software method is configured to control each of the heating elements 31 and 41 according to a pre-programmed ratio in each of the MC oils 32d and 50d according to the temperature value of the temperature adjusting knob 52. Means that. (The scale of the thermostat knob can be subdivided in various ways such as 120, 120/100, 120/80, etc.)

The hairdressing apparatus of the present invention configured as described above is more economical because it is easy to remove the connector 20 that is frequently broken, thereby reducing the cost of the AS, and the main PC 50 and the sub PC 32 are provided. Therefore, the heating element 31 of the upper body 100 and the heating element 41 of the lower body 200 may be controlled differently.

9 and 10 is another embodiment of the present invention, other components are the same as the above-described present invention, but the heat generating portion 40a of the lower body 200 corresponds to the heating plate 30 of the upper body 100 Formed as is another feature.

The heat generating portion 40 of the lower body 200 is formed in a semi-circular shape so that the upper side is in close contact with the heating plate 30 of the upper body 100, the function is formed by the corresponding shape The same as the above, but the time required to heat the heat generating plate 30 and the heat generating unit 40a is the same, so the sub PC ratio 32 can be omitted.

The present invention as described above is not limited to the specific embodiments described above, anyone of ordinary skill in the art to which the present invention belongs without departing from the gist of the present invention claimed in the claims can be variously modified will be.
