Abstract

본 발명은 에어커튼 구조를 갖춘 냉장고에 관한 것으로, 그 목적은 도어 개방시 토출되는 냉기가 에어커튼을 형성하여 저장실내의 냉기가 외부로 유출되는 것을 억제함으로써, 냉장고의 운전효율과 식품의 신선도를 장기간 유지하는 것이다.The present invention relates to a refrigerator having an air curtain structure, and its object is to provide a refrigerator having an air curtain structure, wherein the cool air discharged when the door is opened forms an air curtain to prevent the cool air in the storage room from flowing out, Long-term maintenance.

본 발명에 따른 에어커튼 구조를 갖춘 냉장고는 도어개폐감지부(90)에 의해 도어(30) 개폐를 인지함으로써, 도어(30)가 개방된 경우에는 냉기를 저장실(20) 개방면의 상부에서 하측에서 토출시켜 공기장벽을 형성함으로써, 저장실(20)의 냉기 유출이 억제된다.The refrigerator having the air curtain structure according to the present invention recognizes opening and closing of the door 30 by the door opening / closing detection unit 90 so that when the door 30 is opened, So that the outflow of cool air from the storage chamber 20 is suppressed.

따라서 도어(30)를 자주 열어도 냉기 유출이 적어 냉장고의 운전효율이 증대되고, 저장실(20) 내의 온도가 항상 일정하게 유지되어 저장식품의 신선도를 장기간 지속시키는 이점이 있다.Therefore, even if the door 30 is frequently opened, there is a possibility that the refrigerating and outflowing of the refrigerator is increased and the temperature of the storage chamber 20 is always maintained constant, thereby maintaining the freshness of the stored food for a long period of time.
