Abstract
본 발명은 서미스터(thermistor)과 같은 온도감지소자의 전식을 방지하기 위한 온도감지소자의 전식방지장치에 관한 것으로, 온도감지소자(21)와 일단이 접지된 저항(22)과의 접점이 감압용 저항(23)을 통해 마이컴(20)의 소정포트로 접속되는 구성을 포함하는 온도감지회로에 있어서, 정전압IC(24)을 통해서 공급되는 온도 감지소자용 직류 바이러스전압이 스위칭수단(25)을 통해 상기 온도감지소자(21)에 인가되도록 접속하고, 상기 마이컴(20)의 다른포트를 통해 상기 스위칭수단(25)을 제어하되, 온도감지동작시에만 상기 스위칭수단(25)을 구동시켜 온도감지소자(21)에 바이어스전압이 인가되도록 한 것인다.BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a device for preventing the spread of a temperature sensing element such as a thermistor, wherein the contact between the temperature sensing element 21 and a resistor 22 having one end grounded is used for pressure reduction. In the temperature sensing circuit including the configuration connected to the predetermined port of the microcomputer 20 through the resistor 23, the direct current virus voltage for the temperature sensing element supplied through the constant voltage IC 24 through the switching means 25 It is connected to be applied to the temperature sensing element 21, and controls the switching means 25 through the other port of the microcomputer 20, the temperature sensing element by driving the switching means 25 only during the temperature sensing operation A bias voltage is applied to (21).
