Abstract

The present invention relates to a heat insulating box and a refrigerator provided with the same. The heat insulating box can suppress the generation of thermal bridging in a vacuum heat insulating material and is more energy-saving than before. The heat insulation box (8) has an inner box (10), an outer box (9), a vacuum heat insulation material (1) and a foam heat insulation material (11) filled in the space between the two, and a part of the lower part faces The inner side is recessed to form a mechanical chamber (13) for the compressor (31). A piece of curved vacuum heat insulating material is arranged on the bottom (15) of the heat insulation box (8) and the vertical wall (14) of the mechanical room erected from the bottom from the bottom to the vertical wall. In addition, the outer case has a convex portion (16a) protruding toward the inner case side at least in a range constituting a vertical wall. The vacuum heat insulating material provided from the bottom to the vertical wall is provided in contact with the convex portion, and the vacuum heat insulating material is arranged at a predetermined distance from the outer case other than the convex portion in the vertical wall.

Description

technical field [0001] The present invention relates to a heat insulating box provided with a foam heat insulating material and a vacuum heat insulating material, and a refrigerator provided with the heat insulating box. Background technique [0002] In recent years, from the viewpoint of protection of the global environment and the safety of nuclear power plants, various studies have been conducted on resource saving, energy saving, and especially power saving. [0003] In particular, from the perspective of energy saving and power saving, the technology of arranging a vacuum heat insulating material in a heat insulating box has been developed, and Japanese Patent No. 4778996 discloses that a single piece of vacuum heat insulating material is bent and used. Technology. [0004] Figure 5 It is a cross-sectional view showing the structure of a general vacuum insulation material. [0005] The vacuum heat insulating material 1 is formed into a bag shape in which two outer wr...
