Abstract

본 발명은 전자렌지의 환경에 따른 온도제어장치에 관한 것으로, 종래에는 하나의 마그네트론 온도스위치만 설치되어 있어서, 이상기온시 마그네트론 온도스위치가 오프되어 전자렌지가 동작되지 못하는 문제점이 있었다.The present invention relates to a temperature control device according to an environment of a microwave oven, and in the related art, only one magnetron temperature switch is installed, and thus, the magnetron temperature switch is turned off during abnormal temperature, thereby preventing the microwave oven from operating.

본 발명은 이를 감안하여 주위온도가 정상적인 경우와 이상기온인 경우에 대응해서 오프온도를 서로 다르게 설정한 제1, 제2마그네트론 온도 스위치(1)(2)를 마그네트론에 부착 설치하고, 온도센서(7)를 바람 안내부에 설치하며, 콘트롤러에서 흡입공기 온도를 감지하여 주위온도에 따라 온도 스위치 릴레이(RY1)를 제어하여 상기한 제1, 제2마크네트론 온도스위치(1)(2)중 어느 하나를 선택하도록 구성함으로써, 이상기온시에도 정상동작이 가능하고, 정상적으로 과열방지를 수행할 수 있게 되는 것이다.In view of this, the first and second magnetron temperature switches 1 and 2 in which the off temperature is set differently in response to the case where the ambient temperature is normal and the abnormal temperature are attached to the magnetron, and the temperature sensor ( 7) is installed in the wind guide, and the controller senses the intake air temperature and controls the temperature switch relay RY1 according to the ambient temperature, so that the first and second macronetron temperature switches (1) and (2) By configuring to select one, the normal operation is possible even at abnormal temperature, it is possible to perform the normal overheating prevention.
