no. 1 approach
[0028] Below, refer to Figure 1 to Figure 5 The first embodiment will be described. Such as figure 1 as well as figure 2 As shown, the heat insulating box 1 is constituted by having a heat insulating material in the space between the outer case 2 made of steel plate and the inner case 3 made of synthetic resin, the details of which will be described later. A plurality of storage rooms are provided inside the heat insulating box 1 . Specifically, as figure 2 As shown, a refrigerating room 4 and a vegetable room 5 are arranged sequentially from the upper stage in the interior of the heat-insulating box 1, and an ice-making room 6 and a small freezing room not shown are arranged side by side below them. 6 and the lower part of the small freezing chamber is provided with a freezing chamber 7. An automatic ice making device 8 is provided inside the ice making chamber 6 .
[0029] Both the refrigerator compartment 4 and the vegetable compartment 5 are storage rooms in a ref...
no. 2 approach
[0058] Figure 6 as well as Figure 7 Shows the second embodiment. Hereinafter, portions different from those of the first embodiment will be described. Such as Figure 6 As shown, in this embodiment, the plurality of recesses 64 are not formed on the back plate 60 of the inner box 3 . That is, the vacuum insulation panel 70 is bonded to the back panel 60 of the inner box 3 before foam filling of the foam insulation material.
[0059] More specifically, as Figure 7 As shown, the vacuum insulation panel 70 is adhered to the inner surface of the back panel 54 of the outer box 2 by adhesives such as double-sided tape or hot melt. And, this back panel 54 is disposed so that the surface side of the vacuum insulation panel 70 faces upward. And, on the surface of the vacuum insulation panel 70 (in Figure 7 The center is the upper surface) and is coated with hot melt as an adhesive by a glue roller 72.
[0060] The glue roller 72 includes: a coating roller 73 that contacts t...
no. 3 approach
[0066] Figure 8 shows the third embodiment. Hereinafter, portions different from those of the first embodiment will be described. In addition, in this embodiment, for convenience of description, also refer to figure 2 .
[0067]In the present embodiment, the plurality of recesses 64 are not formed on the back plate 60 of the inner box 3 . Instead, a storage recess 76 protruding toward the inner side of the inner box 3 is formed on the back plate 60 of the inner box 3 . The storage recess 76 is located on the rear side of the refrigerator-side cooler compartment 32 functioning as an air duct. The storage recess 76 extends horizontally from the center position in the vertical direction of the back plate 60 to the position of the chamfered portion 62 . Furthermore, a storage recess 77 protruding inwardly of the inner box 3 is formed on the back plate 60 of the inner box 3 . The storage recess 77 is located in the vicinity of the refrigerator-side cooler chamber 32 , that ...
