또한, 그 구성은 본 발명에 전원을 공급하는 전원공급부(20)와, 히터(H) 및 송풍팬(FAN)을 구동하는 모터(M)를 구비하여 이를 구동시키는 부하구동부(30)와, 숫자표시용 LED(MTX), 전원LED(L1), 전원스위치(S4), 온도설정스위치(S3), 증가스위치(S1) 및 감소스위치(S2)등을 구비하여 현재 고내온도, 설정오도표시, 온도설정등을 해줄수 있는 표시 및 스위치입력부(40)와, 고내에 설치된 제1온도감지소자(TH1)를 통해 고내의 온도를 감지하는 온도감지부(50)와, 히터(H)의 과열을 감지하는 제2온도감지소자(TH)를 통해 히터(H)이 과열을 검지하고, 상기 제1온도감지소자(TH1)의 불량상태 및 제2온도감지소자(TH2)의 불량상태를 검지하여, 상기 과열 및 불량시에 히터(H)의 동작을 중지시키고, 히터동작시에 동작LED(L2)를 점등시키는 과열방지부(60)와, 표시 및 스위치입력부(40)의 전원스위치(S4) 키입력시 전LED(L1)를 점등하고 동시에 부하구동부(30)의 모터(M)가 정격출력이 되도록 하여주고, 온도감지부(50)를 통해 입력되는 고내의 온도를 감지하여 설정한 온도와 동일해지도록 부하구동부(30)의 히터(H)를 온, 오프제어하는 마이컴(10)으로 구성된 것이다.In addition, the configuration is provided with a power supply unit 20 for supplying power to the present invention, a motor (M) for driving the heater (H) and the blowing fan (FAN) and the load driving unit 30 for driving it, and the number LED (MTX), power LED (L1), power switch (S4), temperature setting switch (S3), increase switch (S1) and decrease switch (S2), etc. Display and switch input unit 40 for setting, etc., the temperature sensing unit 50 for sensing the temperature in the interior through the first temperature sensing element (TH1) installed in the interior, and to detect the overheat of the heater (H) The heater H detects overheating through the second temperature sensing element TH, detects a defective state of the first temperature sensing element TH1 and a defective state of the second temperature sensing element TH2, and detects the overheating. And an overheat prevention unit 60 for stopping the operation of the heater H in case of failure and turning on the operation LED L2 during the operation of the heater, and a power supply for the display and switch input unit 40. When the position (S4) key is pressed, all LEDs (L1) are turned on and at the same time, the motor (M) of the load driving unit (30) is rated output, and the temperature detected in the chamber is input through the temperature sensing unit (50). It consists of the microcomputer 10 which turns on and off the heater H of the load drive part 30 so that it may become equal to the set temperature.
