Embodiment Construction

[0013] The present invention will be further described below in conjunction with the accompanying drawings.

[0014] Such as figure 1 , figure 2 As shown, a door body of a freezer compartment of a refrigerator includes a door panel 1, a door cavity 2, an upper positioning plate 31, a lower positioning plate 32, and a foam insulation layer 4, and also includes reinforcement plates 5 made of a plurality of bamboo pole materials. , The reinforcing plate 5 is parallel to the inner cavity 2 of the door. The reinforcing plate 5 is adjacent to the door cavity 2;

[0015] The upper and lower positioning plates 31, 32 can be arranged parallel to the horizontal plane, or perpendicular to the horizontal plane.

[0016] The reinforcing plate 5 has an included angle of less than or equal to 90 degrees and greater than or equal to 0 degrees with the horizontal plane.

[0017] Such as figure 2 As shown, the cross-section of the reinforcing plate 5 perpendicular to its length direction...

Abstract

The invention relates to a door body of a refrigerator freezer room, which comprises a door panel, a door inner chamber, an upper positioning plate, a lower positioning plate and a foam insulation layer as well as a stiffening plate made of a plurality of bamboo rods, wherein the stiffening plate is parallel to the door inner chamber, and an included angle with the plane is formed and is less than or equal to 90 degrees and is greater than or equal to 0 degree. Because of the adoption of such structure, the stiffening plate made of the bamboo rods has toughness so as to effectively neutralize bending deformation force of the door panel and the door inner chamber and keep the original shape of the door so that the door body is prevented from deforming; the stiffening plate made of the bamboo rods has a plurality of bamboo joints which can enforce the combination force between the foam insulation layer and the stiffening plate so that the door body has high integrality and the function of deformation prevention is increased. Compared with metal stiffening plates in the prior art, the stiffening plate made of the bamboo rods has good toughness, high deformation-resistant capability, low cost and light weight.

Description

technical field [0001] The invention relates to a device of a refrigerator, in particular to a door body of a freezer compartment of the refrigerator. Background technique [0002] In the current prior art, a door body of a freezer compartment of a refrigerator comprises a door panel, a door cavity, an upper positioning plate, a lower positioning plate, a metal reinforcement plate and a foam insulation layer, the foam insulation layer wraps the metal reinforcement plate, and The foam insulation layer fixedly connects the door panel, the upper and lower positioning plates and the inner cavity of the door. Existing problems are: high cost, heavy weight of the door body, still does not prevent the door body from bending and deforming in the height direction, and leaks cold air. Contents of the invention [0003] The object of the present invention is to provide a door body of a refrigerator freezer, which can not only effectively reduce the cost and weight of the door body, ...
