Document Type and Number:
WIPO Patent Application WO/2017/201844
Kind Code:

Abstract:
A door opening and closing device, and a refrigerator. A door of the refrigerator is rotatably connected to a refrigerator body by means of a rotating shaft that is fixedly connected to the door. The door opening and closing device comprises a connecting rod (2), a first drive means, a second drive means, and an elastic member (4). The connecting rod (2) is provided on the door and comprises a first end (21) and a second end (22) that matches a shaft hole (201). The first drive means is connected to the connecting rod (2) to drive the connecting rod (2) to rotate. The second drive means is used for driving the connecting rod to move close to the shaft hole (201), and makes the second end (22) of the connecting rod (2) insert into the shaft hole (201). After the second end (22) of the connecting rod (2) is inserted into the shaft hole (201), the elastic member (4) is compressed, so that the elastic member (4) drives the connecting rod (2) to move away from the shaft hole (201). After the second drive means (22) drives the connecting rod (2) to insert into the shaft hole (201), the first drive means drives, by means of the connecting rod (2), the rotating shaft to rotate，so as to make the door rotate relative to the refrigerator body. The door opening and closing device can implement the automatic opening and closing of a door of a refrigerator.
