Refrigerator and manufacturing method thereof

Abstract

The invention provides a refrigerator. The refrigerator comprises a shell, a refrigerating inner container arranged in the shell, a foaming layer arranged between the refrigerating inner container andthe shell and a conduit which extends inwards from the edge of the shell and is buried in the foaming layer, wherein the conduit comprises a rigid pipe and a flexible pipe which are connected with each other, the end, away from the flexible pipe, of the rigid pipe is arranged close to the edge of the shell, and the strength of the flexible pipe is lower than that of the rigid pipe. Therefore, inthe foaming process of the refrigerator, a foaming material can be discharged out from the flexible pipe and used for filling; and since the strength of the flexible pipe is lower than that of the rigid pipe, after the foaming material is gradually increased, the foaming material can extrude the flexible pipe, and consequently the flexible pipe is spaced from the shell or the inner container by acertain distance. After the forming and working of the refrigerator, the flexible pipe is completely buried in the foaming layer, so that the cooling capacity capable of being transmitted is quite limited, and condensation at the position, corresponding to the conduit, on the shell of the refrigerator is prevented.

Description

technical field [0001] The invention relates to the field of refrigerators and their manufacture, in particular to a refrigerator capable of preventing condensation on the backboard of the refrigerator and its manufacturing method. Background technique [0002] With the improvement of people's living standards, people's requirements for refrigerators are also getting higher and higher. In order to ensure its thermal insulation, traditional refrigerators usually have a thicker foam layer, thus occupying a larger area and reducing the usable internal volume. Therefore, with the further development of insulation materials, the insulation layer of refrigerators has been further thinned, and ultra-thin large-volume refrigerators have appeared. [0003] In ultra-thin large-volume refrigerators, the distance between the inner tank and the outer shell is narrower, which means that the space left for the foam layer is also narrower. In order to ensure the foaming speed, the duct use...
