Abstract

본 발명은 전자 레인지에 관한 것으로서, 더욱 상세하게는 전자 레인지 도어 개폐에 연동하는 안전 스위치 미동작시 타이머 모터 구동 전원을 차단하여 마그네트론에 인가되는 고압을 저지할 수 있도록 하는 전자레인지 안전장치에 관한 것이다.The present invention relates to a microwave oven, and more particularly, to a microwave safety device that can block the high pressure applied to the magnetron by shutting off the timer motor driving power when the safety switch is not operated in conjunction with opening and closing the microwave door. .

종래의 전자레인지에 있어서는 제1도에서와 같이 1-2차 안전스위치(SW1)(SW2)가 융착되어 접속 되어지면 교류 전원이 고전압 트랜스(HVT)에 공급되어 전자레인지 도어가 열린 상태에서도 마그네트론에서 고주파가 발진하는 문제점이 있었다.In the conventional microwave oven, as shown in FIG. 1, when the 1st and 2nd safety switches SW 1 and SW 2 are fused and connected, AC power is supplied to the high voltage transformer HVT and the microwave oven door is opened. There was a problem of high frequency oscillation in magnetron.

따라서 본 발명은 이를 개선하기 위하여 제2도와 같이 모니터 스위치(SW4)에 직렬로 퓨우즈(FS)를 연결시켜 1·2차 안전 스위치(SW1)(SW2)가 융착된 상태에서도 고전압 트랜스(HVT)에 인가되는 교류 전원을 차단할 수 있을 뿐만아니라 플러그와 연결된 하우스 브레커의 퓨우즈가 단락되는 것을 방지할 수 있는 것이다.Therefore, in order to improve this, the present invention connects the fuse FS to the monitor switch SW 4 in series as shown in FIG. 2 so that the high voltage transformer can be operated even when the primary and secondary safety switches SW 1 and SW 2 are fused. It can not only cut off the AC power applied to the HVT but also prevent the fuse of the house breaker connected to the plug from being shorted.
