Description

전자레인지의 래치판 취부구조Latch plate mounting structure of microwave oven

일반적으로 조리실 전면에 설치되는 도어에는 후크가 설치되어 있고,상기 후크에 의해 작동되는 1,2차 안전스위치 및 모니터 스위치(이하“ 마이크로 스위치”라 함)가 설치되어 있는 래치판은 전장실에 설치되어 있다.In general, a hook is installed on a door installed in the front of the cooking chamber, and a latch plate on which first and second safety switches and monitor switches (hereinafter referred to as “micro switches”) operated by the hooks are installed in the electrical cabinet. It is.

상기 마이크로스위치는 도어를 개폐할때 도어가 안전하게 개폐되었는지를 검출하는 것으로서,도어가 열렸을때는 전자레인지 작동스위치를 작동시키더라도 고주파가 발진되지 않도록 하고,도어가 닫혔을때는 전자레인지 작동스위치에 의해 고주파가 발진되도록 하는 역할을 한다.The micro switch detects whether the door is safely opened and closed when opening or closing the door. When the door is opened, the micro switch does not generate high frequency even when the microwave operating switch is operated, and when the door is closed, the high frequency is activated by the microwave operating switch. To make it oscillate.

At this time, the primary safety switch is turned on by one pivot lever that the upper hook pivots, and the lower hook is The secondary safety switch is turned on by the remaining two rotating levers, and the monitor switch is turned off. When the operation switch of the microwave is pressed, the power is applied to the high voltage transformer.

반대로 도어를 열면 상/하 후크가 래치판의 괘지공에서 빠져나오면서 회동레버는 원위치되어 1,2차 안전스위치가 오프되고,모니터스위치는 온되어 전자레인지의 작동스위치를 누르더라도 전원이 고압트랜스로 인가되지 못하게 된다.On the contrary, when the door is opened, the upper / lower hooks are released from the latch hole of the latch plate, and the rotation lever is returned to its original position so that the 1st and 2nd safety switches are turned off, and the monitor switch is turned on. It will not be authorized.
