Automatic door opening mechanism of refrigerator and using method of automatic door opening mechanism

Abstract

The invention discloses an automatic door opening mechanism of a refrigerator, and relates to the technical field of refrigerators. The automatic door opening device comprises an automatic door opening device, a door sealing strip and a pump body, wherein the pump body is installed on the outer wall or inside a door body; the door sealing strip is provided with an air bag of a closed structure; a plurality of magnets are fixedly connected to the inner side wall, close to the door body, of the airbag; and the air bag is connected with the pump body through a pipeline and used for injecting a medium into the air bag through the pump body, so that the air bag expands and pulls the magnets away from a refrigerator body. The medium is injected into the air bag of the door sealing strip through the pump body, and the magnets are pulled away from the refrigerator body through expansion of the air bag, so that attraction force between the door body and the refrigerator body is lost, the situation that the door body bounces off suddenly when the automatic door opening device opens the door is avoided, the situations that the refrigerator shakes and the door opening noise is large are effectively avoided, the situation that a user is easily injured due to the fact that the moving speed of the door body is high after the door body is opened is avoided, and the potential safety hazard that a human body is accidentally injured when the refrigerator is automatically opened is effectively eliminated.

Description

technical field [0001] The invention belongs to the technical field of refrigerators, and in particular relates to an automatic door-opening mechanism of a refrigerator and a using method thereof. Background technique [0002] Most of the existing refrigerators need to manually open the door, which is very inconvenient when the user opens the door with items in hand, and the automatic door-opening refrigerator can solve these problems well. At present, there are disclosed automatic door-opening refrigerators, such as the Chinese invention, CN201410242417.9, which discloses an automatic door-opening device for refrigerators and a refrigerator having the same. The technical solution is to control the movement of the ejector rod through gear transmission, and the ejector rod has a large enough thrust to open the refrigerator door during the movement process, thereby realizing automatic door opening. [0003] However, in this type of refrigerator automatic door opening device, ...

AI Technical Summary

Problems solved by technology

[0004] The object of the present invention is to provide an automatic door-opening mechanism for refrigerators. By injecting medium into the air bag of the door seal, the magnet is pulled away from the box by the expansion of the air bag, so that the suction force between the door and the box is lost, which solves the problem of automatic door opening of existing refrigerators. When the door is opened, it is easy to shake, and the door moves faster after opening, which poses a safety hazard
