Refrigerator

Abstract

To improve performance of a freezing cycle by releasing heat from a pipe for heat release using a front part of a side face of an outer package and to improve heat insulating performance by extending a vacuum heat insulating material to a back face side of the outer package, in a refrigerator using the vacuum heat insulating material. In the refrigerator, a package body 1 is structured by providing the vacuum heat insulating material 31 on a back side of the side face of the outer package 2 and filling a foam heat insulating material 3 between the outer package 2 and an inner package 4, a dew preventive pipe 22 of the freezing cycle is provided on a back side of a front face flange of the outer package 2 and the heat releasing pipe 20 of the freezing cycle is provided on the back side of the side face of the outer package 2. The heat releasing pipe 20 is provided so that it vertically extends at a front part of the side face of the outer package 2 and the vacuum heat insulating material 31 is provided so that it extends to the back face side of the outer package 2 from behind the heat releasing pipe 20.

Description

technical field [0001] The invention relates to a refrigerator in which a vacuum heat insulating material is provided on the inner side of the outer box of the box body. Background technique [0002] As a conventional refrigerator of this type, in Japanese Patent Application Laid-Open No. 10-205995 (Patent Document 1) figure 1 ~ Figure 9 and its description are described. [0003] In the refrigerator of this conventional example, while a vacuum insulation material is provided on the side surface of the outer box, a foam insulation material is filled between the aforementioned outer box and the inner box to form a box body, and a vacuum insulation material is placed on the inner side of the front flange of the aforementioned outer box. While there is the anti-condensation pipe of the refrigeration cycle, the heat radiation pipe of the refrigeration cycle is provided with the side inboard of the aforementioned outer case. [0004] A plurality of storage chambers are formed u...

AI Technical Summary

Problems solved by technology

However, when the vacuum heat insulating material is repeatedly installed on the projected surface of the side of the narrow channel part, the thickness of the foamed heat insulating material having the adhesive force connecting the inner box and the outer box becomes thinner, and the narrow channel part of the box body becomes thinner. The strength of the further weakened, resulting in a problematic strength

In particular, as shown in the example of FIG. 8 , when the door 52 of the uppermost refrigerator is installed on the upper and lower sides of the thinned narrow channel through the hinge 53, the weight of the door 52 cannot be supported and the door 52 cannot be stored in the box. Hazard by weight of food within 52a
