Abstract

본발명은 상용교류전원의 변동에 관계없이 전자레인지의 조리실을 밝히는 조명램프의 밝기를 일정하게 유지시킬 수 있도록 한 전자레인지의 램프밝기 안정화장치에 관한 것이다. 본발명의 전자레인지의 램프밝기 안정화장치는 조리실(3)의 내부를 조명하기 위한 조명램프(5)를 구비한 전자레인지에 있어서, 상용교류전압(AC)의 크기를 감지하는 전압감지부(40), 상용교류전압(AC)을 위상제어하여된 전력으로 조명램프(5)를 구동하는 램프구동부(50) 및 전압감지부(40)에서 제공된 감지신호에 의거하여 상용교류전압(AC)의 크기를 판단한 후에 조명램프(5)에 인가되는 전체전력량이 일정해지도록 상용교류전압(AC)의 위상각을 가감시키는 제어신호를 램프구동부(50)에 출력하는 제어부(10)를 구비한다.The present invention relates to a lamp brightness stabilization device of the microwave oven to maintain a constant brightness of the lighting lamp for illuminating the cooking chamber of the microwave oven regardless of the variation of the commercial AC power supply. Lamp brightness stabilizing device of the microwave oven of the present invention is a microwave oven having an illumination lamp (5) for illuminating the interior of the cooking chamber (3), the voltage sensing unit for detecting the magnitude of the commercial AC voltage (40) ), The magnitude of the commercial AC voltage based on the detection signal provided from the lamp driver 50 and the voltage detector 40 for driving the lighting lamp 5 with the power controlled by the phase control of the AC voltage. After determining that the control unit 10 for outputting a control signal to the lamp driving unit 50 to reduce the phase angle of the commercial AC voltage so that the total amount of power applied to the lighting lamp (5).
