Abstract

본 발명은 마이크로웨이브오븐의 자동 조리를 수행하는 기술에 관한 것으로, 적외선 센서를 채택한 종래의 마이크로웨이브오븐에 있어서는 구성이 복잡하고, 음식물이 가열되면서 발생되는 증기에 직접적으로 노출되어 있어 센서의 성능이 저하되는 문제점 등이 있었는 바, 본 발명은 이를 해결하기 위하여 음식물에서 발산되는 적외선을 간접적으로 감지하고, 이를 근거로 음식물의 표면온도 변화를 측정하여 자동조리를 수행함으로써 센서의 과도한 온도상승에 의해 감도가 저하되는 것을 방지하고, 새로운 초기가열방법 및 추가 가열방법을 이용하여 자동요리의 신뢰성을 향상시킬 수 있게 하였다.The present invention relates to a technique for performing automatic cooking of a microwave oven, and in the conventional microwave oven employing an infrared sensor, the configuration is complicated, and the performance of the sensor is directly exposed to steam generated when food is heated. In order to solve this problem, the present invention indirectly detects infrared rays emitted from food and measures the surface temperature change of the food based on this, and performs automatic cooking to sense sensitivity due to excessive temperature rise of the sensor. Is prevented from deteriorating, and new initial heating method and additional heating method can be used to improve the reliability of automatic cooking.
