[0002] A refrigerator is a device that stores items at a constant low temperature to extend the shelf life of the items. A refrigerator generally includes a box body and a door. The box body is structured to form an internal space for storing items. The door has an openable cover on the box body to open or close the internal space of the box body, thereby facilitating the storage or removal of items in the internal space of the box body.

[0003] When the refrigerator is in cooling mode, after the door is opened, the hot air outside the refrigerator enters the refrigerator. If the door is closed at this time, the hot air entering the refrigerator will shrink rapidly due to the cold. Since the refrigerator is a well-sealed container, a large negative pressure will be formed inside the refrigerator. If the door is opened again before the negative pressure disappears, it is necessary to overcome the resistance caused by the negative pressure, so a large pulling force is required to open the door. It is difficult to open the door, and sometimes it may not be opened. Forcing the door to open may cause damage to the door or the cabinet. Summary of the invention
