Abstract
본 발명은 전자렌지의 습도감지 자동조리 제어방법에 관한 것으로, 조리용기의 상태 및 사용조건등에 따라 가열이 계속되어도 습도값이 소폭 증가한후 다시 감소되어 문탁치를 넘지 못하는 경우가 생기는데, 이러한 경우에 조리에러가 발생되는 문제점이 있었다.The present invention relates to a method for automatically detecting and controlling humidity of a microwave oven, and depending on the condition and use conditions of the cooking vessel, even if the heating is continued, the humidity value slightly increases and then decreases again, so that the threshold cannot be exceeded. There was a problem that an error occurred.
본 발명은 이를 감안하여 습도를 감지하여 기준값을 갱신하는 과정과, 습도값이 소정값이상으로 증가 되었다가 다시 습도값이 상기 기준값보다 떨어지는 경우에 무발진 시작플래그를 세트시키는 무발진 준비과정과, 무발진 시작플래그가 세트된 경우에 발진을 중지 시키고, 미리 정해진 일정한 무발진 시간이 경과되면 재발진 시키는 무발진 제어과정과, 현재 습도값의 증가분이 문턱치 이상이 되는 경우에 무발진 시간을 제외시킨 습도감지시간에 의거하여 부가 가열시간을 구하여 조리완료를 제어하는 조리완료 제어과정을 수행하도록 함으로써, 습도가 소폭증가하다 감소되는 경우에 무발진 제어에 의해 충분한 민감도를 가지고 습도를 감지할 수 있게 되어 조리에러를 방지할 수 있게 된다.In view of the above, the present invention provides a process for updating a reference value by sensing humidity, a non-oscillating preparation process for setting a non-oscillation start flag when the humidity value is increased above a predetermined value and then the humidity value falls below the reference value; The oscillation control process stops oscillation when the no oscillation start flag is set, and restarts the oscillation when a predetermined constant oscillation time has elapsed, and humidity that excludes the oscillation time when the increase of the current humidity value exceeds the threshold. By conducting the cooking completion control process to control the cooking completion by obtaining the additional heating time based on the detection time, when the humidity is slightly increased and decreased, it is possible to detect the humidity with sufficient sensitivity by the non-oscillation control. The error can be prevented.
