Abstract

본 발명은 댐퍼를 이용한 에어커튼장치에 관한 것으로, 냉장고용 증발기로부터 토출되는 냉기순환용 닥트를 개폐하여 고 내부의 온도 변화됨을 조절하는 것에 있어서, 상기 냉장고 도어 개폐시 구동하여 상기 냉기순환용 닥트를 선택적으로 개폐하는 댐퍼 구동수단과, 상기 닥트에 연결되어 냉장고 도어 개방시 고 내부전면에 냉기를 토출시켜 에어커튼을 형성하는 냉기 토출구를 구비함을 특징으로 하는 댐퍼를 이용한 에어커튼장치를 제공하며, 냉장고도어 개방시 실내온도와 접하는 내부 전면에서의 온도변화됨을 최소화하여 보관되는 음식품의 신선도를 최적의 상태로서 유지할 수 있는 것이다.The present invention relates to an air curtain device using a damper, in the opening and closing of the cold air circulation duct discharged from the refrigerator evaporator to control the temperature change in the inside of the refrigerator, driving the opening and closing of the refrigerator door to open the cold air duct And a damper driving means for selectively opening and closing, and a cold air discharge port connected to the duct and discharging cold air to the inside of the refrigerator when the refrigerator door is opened to form an air curtain. When opening the refrigerator door, it is possible to minimize the temperature change in the inner surface in contact with the room temperature to maintain the freshness of the food and drink stored in the optimum state.
