Abstract

본 발명은 가스 렌지의 엠피유(MPU) 구동 제어 회로에 관한 것으로, 종래에는 마이크로 컴퓨터(1)가 폭주할 때 릴레이(RYI)가 계속 온상태로 유지함에 의해 엠피유(3)의 접점이 계속 흡착 상태를 유지하거나 릴레이 (RY2)의 접점에 이상 발생시 엠피유(3)에 공급되는 전원을 단속하지 못하면 가스가 누설되는 문제점이 있었다. 이러한 점을 감안하여 본 발명은 부하의 동작 상태를 감지함에 따라 이상 발생을 감지하면 릴레이를 오프시킴으로써 엠피유(MPU)의 전원을 자동으로 차단하여 가스 누설을 방지하도록 구성한 것으로, 본 발명은 부하 상태를 감지함에 따라 이상을 검출하면 부하의 전원을 자동으로 차단함으로 마이크로 컴퓨터의 오동작및 부하 구동회로의 이상에 의한 가스 누설을 방지할 수 있다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an MPU driving control circuit of a gas stove, and conventionally, the contacts of MPU 3 continue to be maintained by keeping the relay RRY on when the microcomputer 1 is congested. When the adsorption state is maintained or an abnormality occurs at the contact point of the relay RY2, when the power supplied to the MP3 is not interrupted, there is a problem of gas leakage. In view of this point, the present invention is configured to prevent gas leakage by automatically shutting off the power of the MPU (MPU) by turning off the relay when detecting an abnormal occurrence according to detecting an operation state of the load. By detecting the abnormality, the power supply of the load is automatically cut off to prevent gas leakage due to the malfunction of the microcomputer and the abnormality of the load driving circuit.
