Problems solved by technology

[0007] (2) Divide and cut the insulation foam layer with a knife. Although the operation process is simple, it is only applicable to the separate foamed door body, but cannot be implemented on the integral foamed door body
Therefore, the layout and fixing of the partition board have high requirements and the process is complicated.

Embodiment Construction

[0022] see figure 1 , figure 2 The door body of the refrigerator is composed of an upper end cover 1, a door panel 2, a lower end cover 3, and a door liner 4, etc. The foam material is injected in the middle, and after the foam material is foamed, matured and solidified, a heat-insulating foam layer 5 is formed; the foam material combines the above The parts are bonded together to form a rigid whole - the refrigerator door.

[0023] see image 3 , The upper, middle and lower parts of the door liner 4 are provided with several grooves or flanges 41 . The groove or flange 41 extends from one side of the door liner 4 to the other side of the door liner 4 , and passes through the steps of the door liner 4 . The specific number of grooves or flanges 41 is determined by the size of the refrigerator door; the larger the refrigerator door, the greater the degree of deformation, and the required number of grooves or flanges 41 also increases accordingly.

Abstract

The invention relates to the technical field of refrigerators of domestic appliances, in particular to a refrigerator door body which comprises an inner door liner (4), a foaming layer and a front door panel (2). The foaming layer is arranged between the inner door liner (4) and the front door panel (2), wherein the inner door liner (4) is provided with a plurality of horizontal grooves or flanges (41). In the invention, the grooves or flanges (41) which can extend and retract freely are arranged on the inner door liner (4), stress generated during the shrinkage distortion of the inner door liner (4) when the inner door liner is cooled can be cushioned effectively, thereby preventing the refrigerator door body from deforming. No door reinforced iron is used in the invention, thereby greatly reducing the material cost of the door body; and only the grooves or flanges (41) are added during the plastic molding of the inner door liner without changing the original processes and producing beats, thus the invention has the advantages of simple and easy implementation, labor saving and material saving.

Description

technical field [0001] The invention relates to the technical field of refrigerators in household appliances, in particular to a refrigerator door body. Background technique [0002] The door body of a refrigerator is generally composed of a door panel, a door liner, an upper end cover, a lower end cover, etc., and heat-insulating foaming material is injected in the middle. On some refrigerators with large doors, there is a problem of deformation of the doors due to cooling. This phenomenon is more prominent for freezers with low temperature requirements in the cabinet or refrigerators (freezers) with larger and longer doors. This kind of deformation of the door body will affect the appearance in the slightest, and in the worst case, the door seal between the door body and the cabinet will produce a gap, which will seriously affect the insulation performance of the refrigerator and increase the energy consumption of the refrigerator. The analysis and calculation of the the...
