Abstract

본 발명은 냉장실내에 구비된 2개의 온도감지센서를 이용하여 상호보완적으로 냉장시스템의 약냉상태를 판단하고 약냉발생시 이를 해제하기 위한 방법에 간한 것으로 특히, 제1온도감지센서, 제2온도감지센서를 포함하는 온도감지부, 고내의 냉각작용을 수행하는 냉각팬, 냉장고에 구비된 콤프레서 및 상기 온도감지부를 통하여 입력되는 고내온도감지값들에 의거하여 약냉이 발생하였는지를 판단하고 그 판단결과에 따라 각각의 해당출력 라인을 통하여 냉각팬 또는 콤프레서를 적합한 방식으로 구동시키는 제어를 수행하는 마이크로컴퓨터로 구성되는 제어방법을 제공함으로서, 평상시에는 냉장고에 구비된 냉각팬구동을 통하여 고내온도를 통상제어하다가 계속하여 감지한 제1 및 제2온도감지센서값이 제1온도 센서감지값이 하강되었는 데에도 불구하고 제2온도센서 감지값에 변화가 없거나 오히려 상승하게 되면 이를 약냉이 발생한 것으로 간주하고 냉각팬과 콤프레서를 동시에 구동시켜 고내온도를 단시간내에 효과적으로 떨어뜨려, 보다 정확하고 신속하게 냉각기능저하에 대처하고 오동작을 방지할 수 있도록 한데 그 특징이 있다.The present invention relates to a method for determining the weak cooling state of the refrigerating system complementarily by using two temperature sensors provided in the refrigerating chamber and releasing it when the weak cooling occurs. In particular, the first temperature sensor and the second temperature sensor On the basis of the temperature sensing unit, a cooling fan performing a cooling operation in the refrigerator, a compressor provided in the refrigerator, and the internal temperature sensing values inputted through the temperature sensing unit, it is determined whether weak cooling has occurred and according to the determination result, respectively. By providing a control method consisting of a microcomputer to perform the control to drive the cooling fan or compressor in a suitable manner through the corresponding output line of the, by the usual control of the internal temperature of the high temperature through the cooling fan drive provided in the refrigerator Even though the detected first and second temperature sensor values fall in the first temperature sensor detection value, If there is no change or rise in the detected value of the second temperature sensor, it is regarded as weak cooling, and the cooling fan and the compressor are simultaneously driven to effectively lower the internal temperature in a short time to cope with the cooling function deterioration more accurately and quickly. It is possible to prevent malfunctions.
