Refrigerator door structure

Abstract

This invention discloses a fridge door structure. It includes anterior plate, lateral decorating part, superior decorating cover, interior decorating cover and fridge door gasket. The lateral decorating part forms the lateral face of fridge. It includes: anterior forming part and plate supporting part which form assembling trough capable of inserting into anterior plate edge. Separating rib protrudes from the plate supporting part along length direction. It avoids foam flowing outwards along the surface of plate supporting part. The superior and inferior decorating covers are arranged at the edge of superior and inferior ends of anterior plate. They match the end part of lateral decorating part respectively. The fridge door gasket is arranged at the opposite of anterior plate. Foams are injected into the frame, which is composed of anterior plate, decorating cover and lateral decorating part. After covering fridge door gasket, the foams are hardened and make thermal insulating layer merge into each component. Foams will not leak. This invention also decreases producing cost.

Description

technical field [0001] The invention relates to a refrigerator, in particular to a refrigerator door structure which can accurately inject foam and prevent the foam foam inside the refrigerator door from leaking. Background technique [0002] FIG. 1 is a schematic diagram of a three-dimensional structure of an existing refrigerator. As shown in FIG. 1 , the main body 1 of the refrigerator roughly adopts a hexahedron structure, and a refrigerating chamber and a freezing chamber (not shown) are arranged on the left and right inside the refrigerator. The refrigerator compartment and the freezer compartment are opened / closed by respective refrigerator doors 3 . On the refrigerator doors 3, refrigerator door handles 5 are respectively arranged. When one side of the refrigerator door 3 is supported by the refrigerator main body 1, it rotates around the hinge 7 on the supported side to selectively open / close the refrigerator compartment and the freezer compartment. [0003] The ...

Problems solved by technology

[0005] However, the prior art has the following disadvantages: the outer refrigerator door and the refrigerator door liner are placed on the foaming jig, and the space formed between the outer refrigerator door and the refrigerator door liner is injected with foaming foam and hardened. The foam expands as it hardens

[0006] At present, in order to solve this kind of problem, it is often used to stick tape on the leaking part and then carry out foaming operation. However, in the process of injecting and foaming, it is necessary to stick tape on the leaking part, so the raw material cost of the product will be increased, and the cost will increase. work time
