Abstract

본 발명은 전자레인지의 용기뚜껑 유무에 따른 가열시간 제어방법에 관한 것으로, 종래에는 요리시 음식물의 수증증발을 방지할 목적으로 용기뚜껑을 사용할 경우에는 동일종류, 동일 부하량에 대해서도 뚜껑의 유무에 따른 센서출력은 부하량이 적고 많음에 따라 달리 나타나는 특성과 유사하게 나타나서 다른 총요리시간이 산출되어 잘못되는 요리결과가 나타나는 문제점이 있다. 따라서, 본 발명은 음식물의 조리용기 뚜껑유무를 써모파일형 적외선센서를 사용하여 판별하고, 또 써모파일형 적외선센서의 출력전압특성을 이용하여 무부하요리를 감지함과 아울러 알맞은 추가가열시간을 산출하여 적절한 자동요리를 행할 수 있도록 한다.The present invention relates to a heating time control method according to the presence or absence of a container lid of a microwave oven, in the case of using a container lid for the purpose of preventing the vaporization of food during cooking, according to the same type, the same load even if The sensor output is similar to the characteristics that appear differently as the load is small and large, resulting in a different cooking time resulting in incorrect cooking results. Therefore, the present invention is to determine the presence or absence of the lid of the food container using a thermopile type infrared sensor, and to detect the no-load cooking by using the output voltage characteristics of the thermopile type infrared sensor and to calculate the appropriate additional heating time Proper automatic cooking is possible.
