Abstract

본 발명은 냉장고의 냉기순환덕트 개폐장치에 관한 것으로서, 증발기 제상시 냉동실과 증발기사이의 공기순환에 의해 냉동실 온도가 급격히 상승하는 것을 방지하도록 한 것이다.The present invention relates to a cold air circulating duct opening / closing device for a refrigerator, and prevents the temperature of the freezing compartment from rapidly rising due to circulation of air between the freezing chamber and the evaporator during evaporator operation.

이와같은 본 발명의 목적은 팬의 회전에 따라 냉동실내로 유입되는 증발기에 의해 냉각된 공기가 냉동실 냉기순환덕트내로 유입되도록 하는 흡입구를 형성하고, 이 증발기 표면에 형성된 성에를 제거하기 위해 제상히터를 작동하는 제상시에는 흡입구를 막고, 정상운전을 할 때는 흡입구가 열리도록 흡입구를 개폐하는 개폐판을 형성함으로서 상기의 목적을 이룰 수 있도록 하였다.It is an object of the present invention to provide an air inlet for allowing the air cooled by the evaporator flowing into the freezer compartment to flow into the freezer compartment circulation duct as the fan rotates and a defrost heater And the opening and closing plate for opening and closing the suction port is formed so as to close the suction port at the time of operation and to open the suction port at the time of normal operation.
