Abstract

본 발명은 전기압력보온밥솥에 관한 것으로서, 특히 전기압력보온밥솥 내부의 압력을 마이컴 포트의 A/D변환 스위치 입력값으로 측정하되, 이 측정된 값을 이용하여 각 공정별로 설정하여 설정하여 둔 최적의 압력상태로 취사가 가능하도록 함으로써 외부의 영향을 받지 않고 항상 균일한 취사가 가능한 전기압력보온밥솥의 압력센서를 이용한 공정제어방법에 관한 것으로, 미리 각 공정별 기준압력 등이 세트된 상태에서 취사공정진행중 우선 공정별 기준압력을 설정하며, 이후 소정의 시간이 경과한 시점에서 마이컴의 A/D포트를 체크하여 현재압력을 인식하되, 현재압력이 기준압력과 동일하면 정상적으로 공정이 진행되도록 하며, 기준압력이 높으면 열량주기를 상승시킨 상태에서 공정이 진행되도록 하고, 기준압력이 낮으면 열량주기를 전하시킨 상태에서 진행되도록 한 특징이 있다.The present invention relates to an electric pressure thermal rice cooker, in particular, the pressure inside the electric pressure thermal rice cooker is measured by the input value of the A / D conversion switch of the microcomputer port, and the optimum value is set and set by each process using the measured value. This method relates to a process control method using a pressure sensor of an electric pressure heating rice cooker capable of cooking uniformly without being influenced by the outside by allowing cooking in a pressure state of cooking. During the process, first set the reference pressure for each process, and then, after a predetermined time has elapsed, check the A / D port of the microcomputer to recognize the current pressure.If the current pressure is the same as the reference pressure, the process should proceed normally. If the reference pressure is high, the process proceeds with the calorie cycle raised. If the reference pressure is low, the calorie cycle is charged. There is a feature that allows the state to proceed.

Claims

In the process of cooking process, the standard pressure is set first during the cooking process, and the current pressure is recognized by checking the microcomputer's A / D port after a predetermined time. If the reference pressure is the same, the process proceeds normally. If the reference pressure is high, the process proceeds with the calorie cycle increased. If the reference pressure is low, the process is performed with the calorie cycle lowered. Process control method using pressure sensor of an electric pressure thermostat rice cooker.
