Embodiment Construction

[0068] Hereinafter, an embodiment will be described with reference to the drawings.

[0069] First, in image 3 , shows the heat insulation box, especially shows the heat insulation box 1 of the refrigerator, the heat insulation box 1 is as Figure 4 As shown, the peripheral wall is formed by separately making the top wall part 1a, the bottom wall part 1b, the left side wall part 1c, the right side wall part 1d and the inner wall part 1e, and assembling these wall parts. body 1 as a whole image 3 As shown in , it is in the shape of a substantially cuboid box with an open front.

[0070] The top wall portion 1a, the bottom wall portion 1b, the left side wall portion 1c, the right side wall portion 1d, and the rear wall portion 1e, which are the above-mentioned respective wall portions, will be described in detail.

[0071] Such as figure 1 As shown, the top wall part 1a includes: an outer shell 2 and an inner shell 3 of the top wall; a vacuum heat insulation panel (first v...

Abstract

PROBLEM TO BE SOLVED: To provide an insulating cabinet capable of obtaining sufficient insulating performance and rigidity.SOLUTION: The insulating cabinet 1 includes a ceiling wall 1a, a bottom wall 1b, a left wall 1c, a right wall, and a depth wall 1e, both or one of the ceiling wall 1a and the bottom wall 1b are configured by filling parts respectively between an outer shell 2, 6 and an inner shell 3, 7 with a vacuum heat insulating panel 4, 8-10, and foam insulation 5 charged to the inside thereof, and the left wall 1c, the right wall, and the depth wall 1e are configured by filling parts respectively between the outer shell 17 and the inner shell 12, 18 with a vacuum insulating panel 19.

Description

technical field [0001] Embodiments of the present invention relate to a heat-insulating cabinet suitable for use in, for example, a refrigerator or a heating box. Background technique [0002] In recent years, household refrigerators tend to increase in capacity, but this increase in capacity is achieved not by increasing the size of the refrigerator, but by reducing the thickness of the surrounding wall of the refrigerator's heat-insulating box. [0003] In this case, even if the peripheral wall of the heat insulating box is relatively thin, it is necessary for the box to ensure sufficient heat insulation performance. For this reason, in addition to filling the foam insulation material, the box body is also constructed using a vacuum heat insulation panel (panel), and furthermore, there is a heat insulation box body that only uses a vacuum heat insulation panel to fill the surrounding wall of the box body (such as Refer to Patent Document 1 and Patent Document 2). [0004...
