Problems solved by technology

Therefore, there is a problem that the appearance of the outer case 11 is poor.
In addition, when the unbonded region S4 alone cannot withstand the shrinkage stress of the foamed heat insulating material 13, the vacuum heat insulating material 21 may even peel off from the inner surface of the outer box 11.

[0102] Embodiments of the present invention will be described below with reference to the drawings. figure 1 It is an exploded perspective view showing the refrigerator of this embodiment, figure 2 It is a perspective view showing part of the outer box 11, image 3 It is a plan view showing a part of the outer case 11 in development.

[0103] The heat insulation box body 10 of the refrigerator 1 is a box shape with an open front. The outer surface of the heat insulation box 10 is formed by an outer case 11 , and the inner surface is formed by an inner case 12 . The outer case 11 is formed into a box shape with an open front by a top plate 11a, side plates 11b, 11e, back plate 11c, and bottom plate 11d made of metal plates such as iron plates. The inner box 12 is a resin molded product, and is divided into a plurality of cooling chambers opened at the front. The space between the outer box 11 and the inner box 12 is filled with foaming heat insulating material (not shown) s...

[0121] Figure 7 It is a plan view showing a part of the outer case 11 of the refrigerator according to the second embodiment in development. In addition, the same code|symbol is attached|subjected to the same part as 1st Embodiment, and description is abbreviate|omitted. Compared with the first embodiment, the second embodiment omits the first adhesive tape 41b and only has the first adhesive tape 41a.

[0122] The end parts 26a, 26b of the vacuum heat insulating material 21 straddle the heat radiation pipe 33 arrange|positioned in multiple rows. Moreover, the end part 26a is being fixed to the outer case 11 by the 1st adhesive tape 41a. On the other hand, the end portion 26b is not covered by the first adhesive tape 41b (refer to image 3 ) is fixed on the outer box 11. Therefore, a space portion 29a is formed at the end portion 26a of the cover material 26, and no space portion is formed at the end portion 26b. On the other hand, a plurality of through holes 42a are fo...

In addition, the same code|symbol is attached|subjected to the same part as 1st Embodiment and 2nd Embodiment, and description is abbreviate|omitted. Compared with 1st Embodiment and 2nd Embodiment, 3rd Embodiment does not affix 1st adhesive tape 41a, 41b to the vacuum heat insulating material 21. As shown in FIG.

[0130] Both ends of the heat radiation pipe 33 in the extending direction are fixed to the outer case 11 by the first adhesive tapes 41a and 41b straddling the parallel arrangement direction. Moreover, the heat radiation pipe 33 is fixed to the outer case 11 by the 2nd adhesive tape 42 overlapped with the 1st adhesive tape 41, and arrange|positioned along the extending direction. The second adhesive tape 42 extends to the outside of the heat insulation box 10 and forms a communication channel. The inside of the groove porti...

Abstract

Provided is a refrigerator that can prevent deformation of an outer case due to an air pressure difference between the interior and exterior of an insulating box body and that can prevent the occurrence of appearance defects. The refrigerator comprises: an insulating box body (10) in which a space between an inner case (12) and a metal outer case (11) has been filled with a foam insulating material; heat dissipation pipes (33) extending in one direction, snaking so as to be disposed in a plurality of parallel rows, having both ends disposed to be in contact with an inner surface of the outer case (11), and having an extending part (33a) at one end thereof that extends out to the exterior of the insulating box body (10); and a vacuum insulation member (21) that is mounted onto the inner surface of the outer case (11) and has a core (25) covered with a covering material (26), the interior of the core being depressurized, and a plurality of groove parts (22) to which the heat dissipation pipes (33) are fitted being disposed therein in parallel. A communication path (43a) that enables communication between the groove parts (22) and the exterior of the insulating box body (10) is provided to the periphery of the extending part (33a), and there is communication between neighboring groove parts (22) in the direction of parallel disposition.

Description

technical field [0001] The present invention relates to a refrigerator equipped with a vacuum heat insulating material in a heat insulating box. Background technique [0002] Patent Documents 1 to 3 disclose conventional refrigerators. In these refrigerators, the box of the main body is constituted by a heat-insulating box, and the heat-insulating box is filled with a foamed heat insulating material between the outer box and the inner box. A heat dissipation pipe is provided on the inner surface side of the outer box, and a vacuum heat insulating material is provided in contact with the heat dissipation pipe. At this time, a groove for fitting the heat radiation pipe is provided on one surface of the vacuum heat insulating material. [0003] In addition, the heat pipe is glued on the inner surface of the outer case by adhesive tape. Thereby, by stably contacting the heat radiation pipe with the outer case, the heat of the heat radiation pipe can be efficiently transferred...
