Abstract

본 발명은 냉장고의 냉기유로 형성에 관한 것으로, 종래의 기술에의한 냉기흐름은 냉장고의 단속운전시 냉장실의 온도가 냉동실의 온도에 비해 먼저 정해진 온도에 도달함으로써 냉장실의 온도가 정해진 온도(3℃)에 도달하게 되면 냉장실 냉기공급 댐퍼가 닫히게 된다. 이때 냉장실 냉기공급 댐퍼가 닫히는 시점에도 냉동실의 온도는 정해진 온도(약 -18℃)에 도달하지 못하므로 냉각기에 의해 냉각된 냉기를 팬에 의해 냉동실 및 냉장실 냉기공급 유로 및 댐퍼입구에 계속해서 공급된다. 이로인해 냉장실 냉기공급 유로내에 냉기가 정체되고 냉기의 압력이 증가하므로 발생하는 유체유동소음을 없애기위해, 냉장실 냉기공급덕트에 중간덕트를 형성하고 이 중간덕트의 끝단부가 냉기귀한로 덕트와 연결되어 냉장실에 냉기공급을 중단할시에 중간덕트를 거쳐 냉기귀한로를 지나 증발기에 도달할수 있도록 하며, 이때 중간덕트와 냉기공급덕트가 교차되는 지점에 냉기유로 변경댐퍼를 설치하는 냉장고의 소음감축 유로변경 장치이다.The present invention relates to the formation of the cold air flow path of the refrigerator, and the cold air flow according to the prior art is a temperature of the refrigerating compartment is determined by the temperature of the refrigerating compartment reaches a predetermined temperature compared to the temperature of the freezer compartment during the intermittent operation of the refrigerator (3 ℃) ), The fridge cold air supply damper is closed. At this time, even when the refrigerator cold air supply damper is closed, the temperature of the freezer does not reach a predetermined temperature (about -18 ° C), so the cold air cooled by the cooler is continuously supplied to the freezer compartment and the cold air supply flow path and the damper inlet by the fan. . This creates an intermediate duct in the cold compartment cold air supply duct and the end of the intermediate duct is connected to the cold air duct to prevent the fluid flow noise caused by the cold air in the cold compartment air supply passage and the increase in the pressure of the cold air. When the cold air supply is stopped, the noise reduction flow path changing device of the refrigerator is installed at the point where the intermediate duct and the cold air supply duct cross the cold duct through the cold noble path through the intermediate duct. to be.
