Abstract

본 발명은 냉장고에 관한 것으로, 그 목적은 도어의 개방시 냉기의 유출을 억제하는 것이다.The present invention relates to a refrigerator, and its object is to suppress the outflow of cold air when the door is opened.

본 발명의 냉장고는 일면이 개방된 저장실(11)과 저장실을 개폐하는 도어(12), 냉기를 생성하는 증발기(14), 증발기에서 생성된 냉기를 송풍시키는 팬(21), 송풍되는 냉기를 저장실로 안내하는 냉기덕트(22)를 구비하는 냉장고에 있어서, 냉기덕트(22)에서 분기되어 그 토출구(32)가 저장실의 개방면 상측까지 연장된 에어커튼용 덕트(31)와 도어(12)의 개페에 따라 직선왕복운동하는 링크(42), 링크(42)의 직선운동에 따라 회전하며 냉기덕트(22)와 상기 에어커튼용덕트(31)를 선택적으로 개폐하는 밸브(50), 상기 밸브(50)의 회전지지축이 되며 상기 링크(42)의 직선운동을 상기 밸브(50)의 회전운동으로 전환하기 위한 크랭크부(46)를 가진 크랭크축(49)을 포함하는 냉기방향전환수단을 특징으로 하는 에어커튼구조를 갖는 냉장고로서, 도어가 열렸을 때에도 냉기의 공기장벽을 형성하여 저장실의 냉기가 외부로 유출되는 것을 억제하기 때문에 도어를 자주 열어도 냉기의 유출이 적어 냉장고의 관리비용이 절감되는 효과가 있으며 저장실내의 온도변화를 줄일 수 있어 저장식품의 신선도를 향상시킬 수 있는 이점이 있다.The refrigerator according to the present invention includes a storage room (11) having one side opened, a door (12) for opening and closing the storage room, an evaporator (14) for generating cold air, a fan (21) for blowing cold air generated in the evaporator, The air duct duct 31 branched from the cold air duct 22 and extending from the discharge port 32 to the upper side of the opening face of the storage compartment and the air duct duct 31 branched from the cold air duct 22, A valve (50) for selectively opening and closing the cool air duct (22) and the duct (31) for the air curtain while rotating in accordance with the linear movement of the link (42) 50), and a crank shaft (49) having a crank portion (46) for converting linear motion of the link (42) into rotational motion of the valve (50) The air conditioner having an air curtain structure, wherein when the door is opened, Since the cooling air is prevented from flowing out to the outside by forming a wall, it is possible to reduce the management cost of the refrigerator due to the leakage of cold air even when the door is opened frequently, and the temperature change of the storage room can be reduced. There is an advantage that it can be improved.
