Abstract
본 발명은 식기 건조기에 관한 것으로, 특히 식기건조기의 히터발열부에 온도센서를 설치하여 이 온도센서에서 감지한 온도가 온도퓨즈(fl)와 바이메탈(Bl)의 중간온도에 도달하면 히터를 오프제어시켜 과열을 방지하도록 한 식기건조기용 히티발열부 과열방지회로에 관한 것으로서, 마이컴(130)의 제어출력으로 구동제어되는 히터구동부(150)의 단속제어로 히터발열부(151)에 전원(AC)이 인가되되, 상기 히터발열부(151)의 히터(HT)에 인가되는 전원(AC)이 온도퓨즈(f1)와 타이메탈(Bl)를 거친후 통하도록 접속된 공지의 것에 있어서, 상기 히터발열부(151)의 히터(HT) 온도를 감지하는 더미스터(TH)와 저항(Rl)(R2)으로 구성된 온도감지부(120)를 마이컴(130)의 입력단(Pl)에 추가로 개재하여 구비하되, 상기 온도감지부(120)에서 감지된 온도가 설정된 온도에 도달한 상태로 판정되면 히터발열부(151)에 인가되는 전원(AC)을 차단제어하여 더 이상 발열이 이루어지지 않도록 제어한 것을 특징이 있다.The present invention relates to a dish dryer, and in particular, a temperature sensor is installed in the heater heating unit of the dish dryer to control the heater when the temperature detected by the temperature sensor reaches an intermediate temperature between the temperature fuse (fl) and the bimetal (Bl). The overheat prevention circuit for the heater heating unit for the dish dryer to prevent overheating, the power supply (AC) to the heater heating unit 151 by the intermittent control of the heater driving unit 150 which is driven and controlled by the control output of the microcomputer 130. Although the power is applied to the heater (HT) of the heater heating unit 151 is connected to pass through the temperature fuse (f1) and the tie metal (Bl) after being known, the heater heating A temperature sensing unit 120 composed of a dummyster TH and a resistor Rl and R2 for sensing the heater HT temperature of the unit 151 is further provided at the input terminal Pl of the microcomputer 130. However, a state in which the temperature detected by the temperature detection unit 120 reaches a set temperature If it is determined by the control block the power (AC) is applied to the heater heating portion 151 is characterized in that a further controlled so as not to heat generation is made.
