Abstract

본 발명은 냉장고의 운전 제어에 관한 것으로, 특히 온도감지 센서의 단선시 압축기와 냉각팬의 운전을 운전/정지를 반복수행케 하여 냉각운전이 정지되어 수리시까지 식품의 손상이 우려되는 문제점을 개선한 냉장고의 온도 제어방법에 관한 것이다.The present invention relates to an operation control of a refrigerator, and in particular, by repeatedly operating / stopping the operation of the compressor and the cooling fan when the temperature sensor is disconnected, thereby improving the problem that food damage is feared until the cooling operation is stopped and repaired. It relates to a temperature control method of a refrigerator.

이와같은 본 발명은, 온도센서에 의해 감지된 냉장고의 고내온도와 센서단선온도(T4), 냉각동작온도(T1) 및 냉각정지온도 (T3)를 비교하는 단계와, 상기 감지온도가 상기 냉각동작온도 (T1)보다 높으면, 압축기 및 냉기 순환 팬을 구동시키는 냉각운전단계와, 상기 감지온도가 상기 냉각정지온도(T3)보다 낮으면, 압축기 및 냉기 순환 팬을 정지시키는 냉각정지단계와. 상기 감지온도가 상기 센서단선온도(T4)보다 더 낮은 온도이면, 센서단선 표시램프를 점등시키는 단계와, 이후. 일정시간을 주기로 냉각운전과 냉각정지를 반복하는 센서고장시의 제어운전 단계를 수행하도록 되어 있다.The present invention compares the internal temperature of the refrigerator detected by the temperature sensor with the sensor disconnection temperature (T4), the cooling operation temperature (T1) and the cooling stop temperature (T3), wherein the sensing temperature is the cooling operation A cooling operation step of driving a compressor and a cold air circulation fan when the temperature is higher than the temperature T1, and a cooling stop step of stopping the compressor and the cold air circulation fan when the sensing temperature is lower than the cooling stop temperature T3. If the detection temperature is lower than the sensor disconnection temperature (T4), turning on the sensor disconnection display lamp. It performs control operation step in case of sensor failure by repeating cooling operation and cooling stop at regular intervals.
