냉동실과 냉장실 그리고 냉각기의 온도를 감지하여 전기적신호를 출력하는 냉동실 온도감지부(1)와 냉장실 온도감지부(2) 및 냉각기의 온도감지부(3), 그리고 냉장고의 온도설정 및 각종 기능키가 구비된 키 입력부(4)가 마이크로프로세서(5)의 입력단에 각각 연결되고, 상기 마이크로프로세서(5)의 출력단에는 냉동실과 냉장실에 냉각공기를 공급해 주는 냉동실 냉각팬구동부(6)와 냉장실 냉각팬구동부(7)가 각각 연결됨과 더불어 냉각공기를 발생시키기 위해 기체화되었던 냉매를 다시 고압으로 압축시키는 콤프레셔구동부(8)가 연결된 구조로 되어 있는 냉장고의 냉각팬 제어장치.The freezer compartment temperature detector (1), the freezer compartment temperature detector (2), the cooler temperature detector (3), the temperature setting of the refrigerator and various function keys are provided. The provided key input unit 4 is connected to an input terminal of the microprocessor 5, respectively, and an output terminal of the microprocessor 5 is a freezer compartment cooling fan driver 6 and a refrigerating compartment cooling fan driver for supplying cooling air to the freezer compartment and the refrigerating compartment. The cooling fan control apparatus of the refrigerator in which the compressor (7) is connected, and the compressor drive part (8) which compresses the refrigerant | gas which was vaporized to generate cooling air again to high pressure is connected.
콤프레셔구동부(8)의 운전개시가 이루어진 후 냉동실온도를 감지하여 냉동실온도(Tf)와 냉각기온도(Td)간의 온도차가 냉동실온도(Tf)와 냉각기온도의 목표값(Td′)간의 온도차보다 클때 냉동실 냉각팬구동부(6)를 구동시키고 크지 않으면 바로 냉장실온도를 감지하도록 하는 단계와, 이어 냉장실온도를 감지하여 냉장실온도(Tr)와 냉각기온도(Td)간의 온도차가 냉장실온도(Tr)와 냉각기온도의 목표값(Td′)간의 온도차보다 크지 않으면 초기단계로 돌아가 콤프레셔구동부(8)를 구동시키지만 상기 온도차가 크면 냉장실 냉각팬구동부(7)를 구동시키는 단계, 이어 냉동실온도(Tf)가 냉각기온도(Td)보다 낮아지면 냉동실 냉각팬구동부(6)의 동작을 차단시키지만 낮지 않으면 바로 냉장실온도(Tr)와 냉각기온도(Td)를 비교하도록 된 단계, 그 비교결과 냉장실온도(Tr)가 냉각기온도(Td)보다 낮으면 냉장실 냉각팬구동부(7)의 동작을 차단시키고 낮지 않으면 초기단계로 돌아가서 상기 과정을 반복하도록 하는 냉장고의 냉각팬 제어방법.After the operation of the compressor driver 8 is started, the temperature difference between the freezer compartment temperature T f and the cooler temperature T d is determined by detecting the freezer compartment temperature between the freezer compartment temperature T f and the target value T d ′. When the temperature difference is greater than the step of driving the freezer compartment cooling fan drive unit 6 and not large, and immediately detects the refrigerator compartment temperature. Then, by detecting the refrigerator compartment temperature, the temperature difference between the refrigerator compartment temperature (T r ) and the cooler temperature (T d ) is the refrigerator compartment temperature ( If the temperature difference between T r ) and the target value (T d ′) of the cooler temperature is not greater than the initial stage, the compressor driving unit (8) is driven, but if the temperature difference is large, the refrigerating chamber cooling fan driving unit (7) is followed. When (T f ) is lower than the cooler temperature (T d ), the operation of the freezer compartment cooling fan drive unit 6 is blocked, but if it is not low, the refrigerator compartment temperature (T r ) is directly compared with the cooler temperature (T d ). result If the refrigerator compartment temperature (T r ) is lower than the cooler temperature (T d ), the operation of the refrigerator cooling fan control unit (7) to block the operation of the refrigerator compartment cooling fan to return to the initial stage to repeat the process if not low.
