Manufacturing method for door body used for refrigerator, door body used for refrigerator and refrigerator

Abstract

The invention relates to a manufacturing method for a door body used for a refrigerator, the door body used for the refrigerator and the refrigerator. The manufacturing method for the door body comprises the following steps that a panel, a door lining, an upper decoration strip, a lower decoration strip and two side frames are provided; the two side frames are fixed to the two side ends of the door lining respectively; the upper decoration strip is fixed to the door lining and the upper side end of at least one side frame, and the lower decoration strip is fixed to the door lining and the lower side end of at least one side frame; the panel is glued to the upper decoration strip, the lower decoration strip and the forward surfaces of the two side frames for enabling the panel to be arranged opposite to the door lining, so that a foaming space is formed among the panel, the door lining, the upper decoration strip, the lower decoration strip and the two side frames; and foaming materials are injected into the foaming space and are subjected to foaming, so that a heat preservation and insulation layer is formed in the foaming space. The door body is made through the manufacturing method. The refrigerator comprises a refrigerator body and the door body made through the manufacturing method, and the door body is connected to the refrigerator body directly or indirectly.

Description

technical field [0001] The invention relates to household appliances, in particular to a method for manufacturing a door body for a refrigerator, the door body for a refrigerator, and the refrigerator. Background technique [0002] A door body for a refrigerator generally includes an outer frame of the door body, a panel and a door liner. The outer frame of the existing refrigerator door body is usually an integral part with a left frame, a right frame, an upper cover and a lower cover. At present, the door body of the existing refrigerator generally adopts the method of mold opening and foaming. After the outer frame and panel of the door body are pre-assembled, the foaming material is injected, and then the door lining is closed, and the door lining, outer frame and panel are fixed together by the adhesive force of the foaming material during the foaming process. [0003] With the diversification of refrigerators, people have higher and higher requirements on the thickne...

AI Technical Summary

Problems solved by technology

However, during the foaming process of the thinner door body, the operation of closing the door liner after injecting the foam material will cause the foam material to overflow, and effective foaming cannot be performed

Just because of the existence of the above-mentioned problems, and there is no effective method that can really solve the above-mentioned problems in the prior art, therefore, there has not been a refrigerator door body with a thinner thickness at present.
