Refrigerator capable of automatically opening and closing door

Abstract

The invention discloses a refrigerator capable of automatically opening and closing a door. The refrigerator comprises a refrigerator body and a door body rotationally connected to the refrigerator body and further comprises a door body pre-opening device for driving the door body to be opened by a preset angle and a door body automatic closing device for driving the door body to be automatically closed. Based on the structure of the refrigerator capable of automatically opening and closing the door, an ejection hook of an ejection extension mechanism can be connected to a butt joint mechanism in a buckled mode when the door body is ejected open, so that the opening speed of the door body is consistent with the moving speed of an ejection rod, and the situation that in the prior art, the door body is rapidly bounced off and operation is not stable is effectively avoided; when the door body is ejected open due to misoperation, the door body can be closed again through the retraction action of the ejection rod, and the problem that a large amount of cooling capacity of the refrigerator capable of automatically opening and closing the door leaks due to misoperation is solved; the door body automatic closing device of the refrigerator capable of automatically opening and closing the door can drive the door body to be automatically closed after the door body is opened, so that user operation is easier.

Description

technical field [0001] The invention relates to the field of household appliances, in particular to a refrigerator with automatic door opening and closing. Background technique [0002] With the continuous improvement of people's living standards, smart home has become an unavoidable development trend, and various smart home products have emerged as the times require. Refrigerators, as an indispensable tool for modern home life, have also become a part of smart home. An important link, intelligent, high-performance refrigerators have become the darling of the market. At present, the door body of the refrigerator is opened manually. When the adsorption force between the refrigerator door body and the box body is too small, it is easy to cause problems such as poor sealing effect of the door body and leakage of cold air; When the adsorption force between the door body and the box body is too large, it is easy to cause the problem that the door body is not easy to open.

AI Technical Summary

Problems solved by technology

However, in the prior art, the method of pre-opening the door with the ejector rod has the following problems: during the opening process of the door body, the force applied by the ejector rod on the door body to overcome the adsorption of the door body at the moment of opening the door is relatively large, and the door body instantly bounces quickly and contacts with the ejector body. The end of the rod is detached, which makes the movement of the door body unstable, which may cause the storage inside the door body to fall down, etc.; in addition, the way the push rod pre-opens the door may also cause the door body to be pushed open due to misoperation. Cases that cannot be closed automatically
