Abstract

본 발명은 에어커튼 구조를 갖춘 냉장고에 관한 것으로, 그 목적은 토출되는 냉기가 저장실 개구면에서 에어커튼을 형성하도록 냉기공급구조를 개선하여 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 an object thereof is to improve a cold air supply structure so that the discharged cold air forms an air curtain at an opening surface of the storage compartment, thereby preventing cold air in the storage compartment from leaking to the outside. It is to maintain operation efficiency and food freshness for a long time.

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 하측으로 강하게 토출시켜 공기장벽을 형성함으로써, 저장실(20)의 냉기 유출이 억제된다. 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.The refrigerator having an air curtain structure according to the present invention recognizes the opening and closing of the door 30 by the door opening / closing detection unit 90, and when the door 30 is opened, the cold air is lowered from the upper side of the storage compartment 20 opening surface. By strongly discharging to form an air barrier, outflow of cold air from the storage chamber 20 is suppressed. Therefore, even if the door 30 is frequently opened, there is less cold air outflow, and thus the operating efficiency of the refrigerator is increased, and the temperature in the storage compartment 20 is constantly maintained, thereby maintaining the freshness of the stored food for a long time.

Claims

A main body provided with a storage chamber having one surface opened therein, a door for opening and closing the opening surface of the storage chamber, an evaporator for generating cold air, a fan for forcedly blowing the generated cold air, and guiding cold air blown by the fan to the storage room. In a refrigerator provided with a cold air duct, a branch branched from the cold air duct 50 and a discharge port 71 is formed above the opening surface of the storage chamber 20 to form an air curtain at the opening surface of the storage chamber 20 when the cold air is discharged. The air curtain duct 70, the air curtain duct 70 is installed in the adjacent portion of the discharge port 71, the door 30 is closed when the door 30 is closed and serves to block the discharge port (71) 30) the refrigerator having an air curtain structure, characterized in that it comprises an auxiliary fan (80) for forcibly blowing cold air to the discharge port (71) at the time of opening.

According to claim 1, The door 30 is provided between the main body 10 and the door opening and closing detection unit 90 for detecting the opening and closing of the door 30, the door opening and closing detection unit 90 is electrically connected And a drive unit (80 ') for driving the auxiliary fan (80) when a signal indicating that the door (30) is opened in the door opening / closing detection unit (90) is input.
