Problems solved by technology

However, regarding the heat insulating material that is plastically deformed by pressing after depressurizing the outer covering, it becomes thinner due to the stretching of the outer covering by the plastic deformation.
As a result, the airtightness of the outer package may be reduced, which in turn leads to a reduction in the thermal insulation performance of the insulation material.

no. 1 Embodiment approach

[0031] First, refer to Figure 1 to Figure 5 , and the first embodiment will be described. Such as figure 1 As shown, the refrigerator 10 is configured by having a plurality of storage chambers in a longitudinally long rectangular heat-insulating box 20 with an open front surface. In the following description, the opening side of the refrigerator 10 is referred to as the front side of the refrigerator 10 , and the side opposite to the opening is referred to as the rear side of the refrigerator 10 . In addition, after setting the refrigerator 10 to figure 1 When the refrigerator 10 is installed on the ground, the up-down direction corresponding to the direction of gravity is defined as the up-down direction of the refrigerator 10 . In addition, when viewed from the front side figure 1 In the case of the refrigerator 10, let the left-right direction be the left-right direction of the refrigerator 10. In addition, regarding the refrigerator 10, the inside of each storage roo...

no. 2 Embodiment approach

[0083] Next, refer to Figure 6 ~ Figure 8 , and the second embodiment will be described. In this embodiment, the vacuum insulation panel 30 further includes the third member 53 . The third member 53 is formed in a plate shape, and is composed of another member different from the first member 51 and the second member 52 . The third member 53 is provided on the first surface 31 side of the first member 51 and is in contact with the peripheral portion 512 which is a portion adjacent to the recessed portion 33 . In this case, the third member 53 is arranged to constitute a plane parallel to the first surface 31 and the second surface 32 . The third member 53 and the peripheral portion 512 may be bonded together with an unillustrated adhesive.

[0084] The third member 53 is configured to have lower compressibility than the first member 51 and the second member 52 . In other words, the third member 53 is configured to be more rigid than the first member 51 and the second membe...

no. 3 Embodiment approach

[0091] Next, refer to Figure 9 , and the third embodiment will be described. Such as Figure 9 As shown, the outer cover 40 has a first portion 401 and a second portion 402 . The first portion 401 is provided in a portion of the outer cover 40 covering at least a part of the peripheral portion 512 of the first member 51 . The second portion 402 is provided in a portion of the outer case 40 that covers the second member 52 .

[0092] The rigidity of the first part 401 is higher than that of the second part 402 . In the present embodiment, for example, the first portion 401 is configured to increase the rigidity by increasing the thickness of the cover material 40 to be thicker than the thickness of the second portion 402 . That is, it is configured such that a resin film is attached to a portion corresponding to the first portion 401 of the outer cover 40 from the outside. In addition, the first part 401 can be configured to increase the rigidity by increasing the thickne...

Abstract

The invention provides a heat insulation material, a refrigerator provided with the heat insulation material, and a manufacturing method of the heat insulation material. The heat insulation material having a recessed shape can inhibit the reduction of the air tightness of an outer covering member and improve the heat insulation performance. The heat insulation material is configured in a plate shape by accommodating a core material in an air-tight outer covering material and decompressing the inside of the outer covering material, and is provided with a recessed portion which is formed by recessing at least a first surface when one side of the plate-shaped surfaces is used as the first surface and the other side is used as a second surface. The core material includes: a first member; and a second member comprising a member having higher compressibility than the first member. The second member forms at least a part or all of the shape of the recessed portion, and the second member is provided closer to the recessed portion side than the first member.

Description

technical field [0001] Embodiments of the present invention relate to a heat insulating material, a refrigerator, and a method of manufacturing the heat insulating material. Background technique [0002] Conventionally, there is a plate-shaped heat insulating material called a vacuum insulation panel. The heat insulating material is configured by accommodating a core material having heat insulating performance in an airtight outer covering and sealing the inside of the outer covering. stress reliever. When a refrigerator is provided with such a heat insulating material, for example, it is necessary to provide a groove shape for accommodating a heat radiation pipe in the heat insulating material. That is, it is required to form desired concave shapes such as grooves on the surface of the heat insulating material. [0003] For example, there is known a heat insulating material formed by decompressing the inside of the cover material to form a plate shape, and then pressing t...
