Abstract

본 발명은 밥솥의 온도 제어회로에 관한 것으로, 특히 취사시 및 보온시 정확한 온도제어를 통해서 최적의 취사 및 보온성능 향상을 도모코자 한것으로서, 이러한 본 발명의 목적은 사용자가 취사 및 보온을 위해 키패드를 통해 밥솥에 신호를 인가하면 마이콤은 이를 인식하고 히터를 가열시킬때 변화되는 오븐외부의 온도를 감지하여 온도를 제어하게 되는데 이때 이 온도제어방법은 기존의 방식과 달리 기준전압을 서로 다르게 선정하고 이 기준전압을 더어미스터(TH1)(TH2)로 감지하여 마이콤에 입력하면 마이콤은 3단계 온도범위에 따른 데이타 분석으로 정밀한 온도 제어를 하게 되는 것이다.The present invention relates to a temperature control circuit of a rice cooker, and in particular, to improve the optimum cooking and warming performance through accurate temperature control during cooking and warming, the object of the present invention is the user's keypad for cooking and warming When the signal is applied to the rice cooker, the microcomputer recognizes this and senses the temperature outside the oven when the heater is heated to control the temperature. In this case, the temperature control method is different from the conventional method. When this reference voltage is detected by thermistor (TH1) (TH2) and input to the microcomputer, the microcomputer performs precise temperature control by analyzing the data according to the three-step temperature range.
