STRUCTURE FOR OPENING AND CLOSING DOOR OF REFRIGERATOR BY PUMPING AIR

摘要

PURPOSE: Structure for opening and closing a door of a refrigerator by pumping air is provided to open and close the door easily with little force, and to store food securely without spilling in the refrigerator by restricting overload from being applied to the door. CONSTITUTION: A door opening and closing system of a refrigerator is composed of a first air bag(5) mounted to a door grip(4) of the refrigerator and deformed against external force and restored spherically; a second air bag(6) expanded by contraction of the first air bag and restored, and attached near a gasket of the rear part of the door; and an air tube installed in the door grip and the door to stream air through the first air bag and the second air bag. The first air bag is contracted by holding the door grip, and the second air bag is expanded by transmitting air from the first air bag to the second air bag through the air tube. The gap is formed between the door gasket and the body of the refrigerator compartment by pressing the side of the second air bag to the body of the refrigerator compartment to open the door easily.
