Refrigerator door self-closing structure and refrigerator

Abstract

A refrigerator door self-closing structure provided by the present invention includes an upper hinge mechanism and a lower hinge mechanism arranged on the upper and lower sides of the refrigerator door. The upper hinge mechanism includes an upper hinge seat, and the upper hinge seat includes a hinge shaft and a shaft sleeve. The top of the shaft is provided with a shaft groove opposite to the hinge shaft. The shaft sleeve is inserted into the shaft slot and has the freedom to move up and down along the shaft slot. The space between the bottom of the shaft sleeve and the bottom of the shaft slot is filled with a compression spring; The hinge mechanism includes a lower hinge seat arranged at the bottom of the refrigerator door body, and a support hinge seat below the lower hinge seat located on the front side of the bottom corner of the refrigerator. The opposite surfaces of the lower hinge seat and the support hinge seat have upper sliding edges and Slide the edge down. During the closing process of the refrigerator door body, the upper sliding edge and the lower sliding edge in the present invention can gradually realize mutual bite, and the compression spring gradually rebounds from the compressed state, and uses its resilience to provide closing strength for the automatic closing of the refrigerator door body. Thereby, the refrigerator door body can be completely self-closing.

Description

technical field [0001] The invention belongs to the technical field of refrigerators, and in particular relates to a refrigerator door self-closing structure and a refrigerator. Background technique [0002] In the prior art, the refrigerator door and the box are mostly connected by hinges. After people use the refrigerator, if the force is light when closing the refrigerator door, it is easy to cause the refrigerator door to not be closed properly, causing the refrigerator to close. The cold air inside will disperse outward, which will make the compressor work for a long time, which not only wastes electric energy, but also has the risk of burning out the compressor. Contents of the invention [0003] The object of the present invention is to overcome the shortcomings of the above-mentioned prior art, and provide a refrigerator door self-closing structure that can successfully complete the self-closing process after the refrigerator door is closed at a certain angle. [...
