Abstract

본 발명은 전원코드(100)를 꽂은 상태에서 아우트판넬(Out pannel)분리시에 입력전원을 자동으로 차단하는 전자렌지의 전원차단장치에 관한 것으로써, 캐비티(10), 프론트판넬(20), 백판넬(30), 베이스판넬(40) 및 아우트판넬(50)의 결합에 의해 일정공간을 형성하는 조리실(60)을 구비하는 전자렌지에 있어서, 상기 아우트판넬(50)이 캐비티(10)로부터 분리되었는지를 감지하는 광센서(102)와, 상기 광센서(102)에 의해 감지된 신호에 따라 입력전원을 제어하는 마이컴(106)과, 상기 마임컴(106)의 제어에 따라 입력전원을 차단하도록 솔레노이드(110)를 구동하는 솔레노이드구동부(108)와, 상기 솔레노이드(110)의 구동에 따라 전원코드(100)로부터 입력되는 전원을 차단하는 안전스위치(112)로 이루어진 것으로, 제품의 고장수리시 전원코드(100)을 꽂는 상태에서 아우프판넬(50)을 분리하더라도 전원을 자동으로 차단하여 감전사고를 미연에 방지할 수 있다.The present invention relates to a power cut-off device for a microwave oven which automatically cuts off an input power when an out pannel is disconnected while a power cord 100 is plugged in. The power cutoff device includes a cavity 10, a front panel 20, The microwave oven according to any one of claims 1 to 3, wherein the cooking chamber (60) is formed by a combination of a back panel (30), a base panel (40) and an outer panel (50) A microcomputer 106 for controlling the input power according to a signal sensed by the optical sensor 102, and a controller 108 for controlling the input power source A solenoid driving unit 108 for driving the solenoid 110 and a safety switch 112 for shutting off the power inputted from the power cord 100 according to the driving of the solenoid 110. In case of repairing the product, When the power cord 100 is plugged in, the outboard panel 50 Even if it is disconnected, it is possible to prevent the electric shock accident in advance by automatically shutting off the power supply.
