Abstract

본 발명은 전자렌지의 도어 오픈 검출장치에 관한 것으로, 종래에는 도어 후크에 의해 직접 및 그 후크에 의해 회동되는 오픈레버에 의해서 마이크로 스위치의 접점을 제어하여 도어의 열림/닫힘을 검출하도록 되어 있는데, 이는 기구적인 구성이 복잡한 문제점이 있다.The present invention relates to a door open detection device of a microwave oven. In the related art, a contact of a micro switch is controlled by a door hook directly and by an open lever rotated by the hook to detect opening / closing of a door. This has a complicated mechanical configuration.

본 발명은 이를 감안하여 메인 회로기판(103)에 광센서(11)를 취부하고, 콘트롤판넬(102)의 도어측 측벽에 상기 광센서(110)의 빛이 통과되는 구멍(120)을 형성하며, 그 구멍(120)에 대응된 위치의 도어(101) 측벽에 반사판(130)을 부착하여 도어의 닫힘/열림을 검출하도록 구성된 전자렌지의 도어 오픈검출장치를 제공함으로써, 조립성을 향상시키고, 신뢰성을 높일수 있게 된다.In view of this, the optical sensor 11 is mounted on the main circuit board 103, and a hole 120 through which the light of the optical sensor 110 passes is formed at the side wall of the control panel 102. By attaching a reflector plate 130 to the side wall of the door 101 at a position corresponding to the hole 120, by providing a door open detection device of a microwave oven configured to detect the closing / opening of the door, It can increase the reliability.
