Abstract
본 발명은 역류방지밸브를 구비한 냉기 덕트에 관한 것이다. 종래기술에 따른 냉장고에 있어서, 냉동실용 송풍팬이 가동 중이고, 냉장실용 송풍팬이 비가동 중일 경우에, 상기 냉장실용 송풍팬의 후방에 형성되는 저압부에 의애 냉장실 내의 냉기가 냉장실용 송풍팬의 후방으로 역류하는 문제점이 있었다. 본 발명의 목적은 위와 같은 냉장실 내의 냉기의 역류를 방지해 줄 수 있는 역류방지밸브를 구비한 냉기 덕트를 제공하는 것이다. 위와 같은 목적을 달성하기 위하여 본 발명에서는, 냉장고의 냉기덕트에 있어서, 냉장실용 송풍팬이 비가동중이고, 냉장실용 송풍팬이 가동중일 때, 상기 냉장실용 송풍팬의 후방에 형성되는 저압부의 흡인력에 의해 냉장실의 내의 냉기가 상기 냉기 덕트를 통해 상기 냉동실로 역류하는 것을 방지하도록 된 역류방지밸브를 구비하는 것을 특징으로 하는 역류방지밸브를 구비한 냉기 덕트를 제공한다.The present invention relates to a cold air duct having a non-return valve. In the refrigerator according to the prior art, when the freezing chamber blowing fan is in operation and the refrigerating compartment blowing fan is inactive, the cold air in the refrigeration chamber is lower than the low pressure portion formed at the rear of the refrigerating compartment blowing fan. There was a problem of backflowing backwards. An object of the present invention is to provide a cold air duct having a non-return valve for preventing the back flow of cold air in the refrigerating chamber as described above. In order to achieve the above object, in the present invention, in the cold air duct of the refrigerator, when the refrigerating compartment blowing fan is inactive and the refrigerating compartment blowing fan is in operation, the suction force of the low pressure portion formed at the rear of the refrigerating compartment blowing fan is maintained. There is provided a cold air duct having a non-return valve for preventing a cold air in the refrigerating compartment from flowing back into the freezer compartment through the cold air duct.
