Abstract
본 발명은 냉기 순환용 팬 모터의 전면부 풍압의 변화를 감지하여 증발기에 성애 착상을 자동으로 제어할 수 있게 되는 냉장고의 제상 장치 및 그 제어 회로에 관한 것으로서, 본체와, 상기 본체의 후면부에 냉기를 생성하도록 배설된 증발기와, 상기 증발기에서 생성되는 냉기를 고내에 순환시키도록 배설된 팬 및 모터와,상기 증발기에 착상된 성애를 가열하여 제거시키도록 장착된 제상 히터와, 상기 증발기의 냉매를 흡입하여 고온 고압으로 압축하는 압축기를 구비하는 냉장고에 있어서, 상기 팬의 전면부에는 풍압의 세기에 따라 왕복 작동되는 풍압 감지 수단과, 상기 풍압 감지 수단의 작동에 따라 제상 히터에 전원을 공급할 수 있도록 온/오프되는 스위칭 수단을 구비하는 것을 특징으로 하는 한편, 제상 히터와, 압축기와 팬의 병렬 연결과 상기 제상히터에 전원 공급을 스위칭하는 스위칭 수단과, 고내의 성애 형성으로 인한 괜의 풍압 감소를 검출하여 제상시작 제어 신호를 발생하는 재상 시작 검출 수단과, 제상 종료를 검출하여 제상 종료 제어 신호를 발생하는 제상 종료 검출 수단과, 상기 제상 시작 재어신호에 응답하여 제상 히터로 전원을 공급하고 상기 제상 종료 제어 신호에 응답하여 제상 히터에 공급되는 전원을 차단하고 소정 시간이 지난 후에 압축기와 팬에 전원을 공급하도록 상기 스위칭 수단을 구동하는 구동수단을 구비하는 것을 특징으로 한다.The present invention relates to a defrosting apparatus and a control circuit of a refrigerator which detects a change in wind pressure of the front part of a cold air circulation fan motor to automatically control defrosting on an evaporator, and a main body and cold air at a rear portion of the main body. An evaporator disposed to generate a heat sink, a fan and a motor disposed to circulate cold air generated in the evaporator in a refrigerator, a defrost heater mounted to heat and remove the frost formed on the evaporator, and a refrigerant of the evaporator. A refrigerator having a compressor that sucks and compresses to a high temperature and high pressure, wherein the front part of the fan is configured to supply power to a defrost heater according to an operation of the wind pressure sensing means reciprocating according to the wind pressure intensity and the operation of the wind pressure sensing means. A switching means switched on / off, and in parallel with the defrost heater, the compressor and the fan, Switching means for switching the power supply to the defrost heater, Defrost start detection means for detecting the deterioration of the wind pressure due to the formation of the defrost in the furnace and generating a defrost start control signal, Detecting the end of the defrost to generate the defrost end control signal Defrost end detection means and power supply to the defrost heater in response to the defrost start control signal, the power supplied to the defrost heater in response to the defrost end control signal is cut off and the compressor and the fan after a predetermined time And driving means for driving the switching means.
