Door body and refrigerator-freezer

Technical Field

The utility model belongs to the technical field of freezers, and particularly relates to a door body and a freezer.

Background

With the continuous development of ice chest technology, high volume, low volume ice chests have become one of the important criteria of choice for users. The volume of the ultrathin freezer is larger with the same floor area; and the transportation cost and the storage cost of the ultrathin freezer can be reduced. Thus, ultra-thin ice chests are preferred by both the consumer and the manufacturer. To make an ultra-thin ice chest, the thickness of the insulation layer of the ice chest can be reduced. However, as a result of reducing the thickness of the insulation layer of the ice chest, the overall thermal load of the ice chest is increased, which directly results in the reduction of the insulation performance of the ice chest, the increase of energy consumption and the increase of the risk of external condensation. In the prior art, the thickness of the heat insulation layer is reduced mainly by adding a vacuum heat insulation plate in a box body or a door body to improve the heat insulation performance of the heat insulation layer. However, in order to ensure the aging resistance of the vacuum insulation panel, the surface of the vacuum insulation panel is coated with a layer of aluminum film, and the aluminum film can partially transmit along the lead film to generate a heat bridge effect. And the prior art is difficult to simultaneously consider the ageing resistance and reduce the heat bridge effect.

The two opposite side edges of the vacuum insulation panel body are respectively provided with the bendable structures, so that the heat transfer path of the vacuum insulation panel body can be effectively prolonged, and the edge heat bridge effect of the vacuum insulation panel is reduced. However, in the structure, the vacuum insulation panel is changed into a three-dimensional structure from a flat structure and is fixed in the foaming cavity, namely, the vacuum panel is connected with the shell of the refrigerator through the bending structures at the two ends, and in the actual foaming process, the bending structures at the two ends can influence the space fluidity of the foaming liquid in the foaming cavity, so that the foaming liquid is not uniformly molded after being solidified, namely, the heat insulation performance of the heat insulation layer is reduced.
