Abstract

본 발명은 에어커튼 구조를 갖춘 냉장고에 관한 것으로, 그 목적은 도어 개방시 토출되는 냉기가 에어커튼을 형성하여 저장실내의 냉기가 외부로 유출되는 것을 억제 함으로써, 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 냉장고의 압력감지센서(90)에 의해 도어(30)가 개방될 것을 미리 예측하여 냉기를 저장실(20)의 개방면 상부에서 하측으로 토출시킴으로써, 도어(30)가 개방되었을 때는 토출냉기가 공기장벽을 형성함으로써, 저장실(20)의 냉기 유출이 억제된다.The door 30 can be prevented from being opened by the pressure sensing sensor 90 of the refrigerator having the air curtain structure according to the present invention and the cold air can be discharged from the open top of the storage room 20 downward, The discharge chilled air forms an air barrier, 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 중대되고, 저장실(20)내의 온도가 항상 일정하게 유지되어 저장식품의 신선도를 장기간 지속시키는 이점이 있다.Therefore, even if the door 30 is frequently opened, the refrigerating efficiency is great because the refrigerant flows out little, and the temperature in the storage chamber 20 is always kept constant, thereby maintaining the freshness of the stored food for a long period of time.
