Abstract

본 발명은 냉장실 팬의 정상 동작 여부를 검출하여 표시해 줌으로써 애프터서비스 담당자가 팬 구동부의 이상시 신속히 대처하도록 한 냉장고의 냉장실 팬 동작불량 검출장치 및 그 방법에 관한 것이다.The present invention relates to a refrigerator operation failure detection device and method for a refrigerator, which detects and displays normal operation of a refrigerator compartment fan so that an after-service representative can quickly respond to an abnormality of the fan drive unit.

이러한 본 발명은 냉장실 팬의 동작상태를 검출하는 냉장실 팬 동작상태 검출부를 구비한다.The present invention includes a refrigerator compartment operation state detection unit for detecting an operation state of the refrigerator compartment fan.

제어부는 냉장실 온도 감지부를 통해 냉장실의 온도를 검출하고 냉장실 팬의 구동 여부를 판단하여 검출한 냉장실 온도가 냉장실 팬 오프온도이며 냉장실 팬 오프신호를 출력하고 냉장실 팬 동작상태 검출부의 출력신호를 검색하여 냉장실 팬이 구동되는 상태이면 고장으로 연속동작되고 있다고 판단하고 이를 표시토록 제어한다.The control unit detects the temperature of the refrigerating compartment through the refrigerating compartment temperature detection unit and determines whether the refrigerating compartment fan is driven. The detected refrigerating compartment temperature is the refrigerating compartment fan off temperature, outputs the refrigerating compartment fan off signal, and retrieves the output signal of the refrigerating compartment fan operation state detection unit. If the fan is running, it is determined that it is continuously operating due to a failure and control to display it.

또한, 검출한 냉장실 온도가 냉장실 팬 구동온도이면 냉장실 팬 구동신호를 출력하고, 냉장실 팬 동작상태 검출부의 출력신호를 검색하여 냉장실 팬이 오프된 상태이면 고장으로 구속상태에 있다고 판단하고 이를 표시토록 제어하게 되는 것이다.In addition, if the detected refrigerating compartment temperature is the refrigerating compartment fan driving temperature, the refrigerating compartment fan driving signal is outputted, and if the refrigerating compartment fan is turned off, it is determined that the refrigerating compartment fan is in a restrained state and is displayed. Will be done.
