Abstract

본 발명은 기계식 댐퍼를 채용한 냉장고에 있어서, 냉동실의 고내온도가 설정온도로 떨어지지 않는 상태에서 콤프레서와 냉동실 팬이 계속가동되는 비정상 운전상태에서 상기 댐퍼를 통한 냉기유입에 의해 냉장실이 과냉되는 것을 방지하도록된 냉장고의 냉장실 과냉방지방법에 관한 것이다.The present invention relates to a refrigerator using a mechanical damper to prevent the refrigerating compartment from being overcooled by the inflow of cold air through the damper in an abnormal operating state in which the compressor and the freezer compartment fan continue to operate in a state in which the interior temperature of the freezing compartment does not fall to the set temperature To a method for preventing supercooling of a refrigerating compartment of a refrigerator.

기계식 댐퍼는 기구적인 구조상 고장발생이 발생할 수 있으며 완전히 닫아주더라도 미세한 틈을 통해 냉장실 고내로 냉기가 새게되므로, 특히 비정상적 운전상태에서 냉장실의 고내온도가 과냉되는 단점이 있다.Mechanical damper may cause a malfunction due to a mechanical structure. Even if the mechanical damper is completely closed, cold air leaks into the refrigerator compartment through a fine gap.

본 발명의 방법에 의하면, 현재 냉동실의 온도가 떨어지지 않는 상태에서 콤프레서와 냉동실 팬이 계속적으로 구동되는 비정상적 운전상태인 것으로 판단되면, 냉장실의 고내온도가 과냉상태인가를 판단하고, 과냉상태일 경우 구동중인 냉동실 팬을 '오프'시킴으로서 기계식 댐퍼를 통한 계속적인 냉기유입에 의한 냉장실의 과냉 현상을 방지하게 된다.According to the method of the present invention, it is determined that the internal temperature of the refrigerating compartment is in a supercooled state when it is determined that the compressor and the freezer compartment fan are continuously operated in a state where the temperature of the freezing compartment is not lowered. The freezing chamber fan is turned off to prevent over cooling of the refrigerating chamber due to continuous inflow of cold air through the mechanical damper.
