Description

[Detailed Description of the Invention] The purpose of this invention is to improve the assembly strength of a heat insulating box for a storage, as well as to form a complete seal and prevent heat transfer between the inside and outside of the storage.

Generally, a storage such as a refrigerated showcase has side walls 1, 1. Its side wall 1,
1 room, ceiling wall 2. Back wall 3. A bottom wall 4 and a front wall 4' are provided to form a heat insulating box, and the inside of the heat insulating box is cooled by a refrigeration device such as a compressor and a cooler 5 installed in the bottom space of the heat insulating box. Food placed in the refrigerator is kept refrigerated.

By the way, there is a high demand for the so-called series of storages, which have the same height and depth but different widths depending on the installation location, stored items, etc.

However, conventionally, insulating boxes for storage boxes with different widths have been manufactured separately, resulting in high costs.

It has also been considered to construct a storage insulating box body by dividing it into two insulating box bodies and connecting both insulating box bodies, but the connecting part is not sufficient and the assembly strength is incomplete. .

This idea was made with the above points in mind,
Next, this invention will be explained in detail with reference to the drawings from FIG. 3 showing an embodiment thereof.

As shown in FIG. Tenbu 7. Bottom 8. Back 9
and the left side insulation box element 11 consisting of the front part 10 and the side parts 6',
The right insulating box element 11' consists of a top part 7', a bottom part 8', a back part 9' and a front part 10', and as shown in FIG. ' are connected in a plane of symmetry to form a single body, thereby forming a heat insulating box body 12 of the storage.

At this time, the width of the heat insulating box 12 is made to match the minimum width of a series of storage storage models having the same height and depth and different widths.

That is, the heat insulating box 12 composed of the left and right heat insulating box elements 11 and 11' is the heat insulating box with the minimum width of the series models.

Next, means for connecting the two heat insulating box bodies 11 and 11' will be explained with reference to FIGS. 5 to 9.

As shown in FIG. 8, at the joint between the two insulation box elements 11 and 11', the joint surface 14- of the outer wall 13 of the left insulation box element 11 is made to protrude to the right than the joint surface 16 of the inner wall 15. In addition, the inner wall 1 of the right heat insulation box element 11'
5' joint surface 16' from the joint surface 14' of the outer wall 13',
It is formed to protrude to the left so as to correspond to the joint surfaces 14 and 16 of the outer wall 13 and the inner wall 15 of the right heat insulation box body 11.

Note that the joint surfaces of each mold 13.13' and 15.15' are formed by bending the joint edges.

Then, screw the square main block 17 with screws 18. Secure firmly with tape, adhesive, etc.

On the other hand, a spacer 20 having a low cross section and a through hole 19 is firmly fixed to the inner wall 15' of the right heat insulation box element 11' corresponding to the fixed outer wall 13 of the main block 17 with adhesive or the like. At the same time, the through hole 1 of the spacer 20 is formed in the inner wall 15'.
An injection hole 21 facing 9 is formed.

Then, the joint surface 1 of the joint part of both the insulation box elements 11 and 11'
After joining 4.14' and 16.16' with adhesive,
Insert the connecting screw 22 into the spacer 20 through the injection hole 21,
Insert the connecting screw 22 into the through hole 19 of the spacer 20 and screw it into the main block 17.
0 to the main block 17, and then tighten the main block 17.
The spacer 20 and the connecting screw 22 unite the two insulation box bodies 11.11', and integrally foam the outer wall 13.13' and the inner wall 15.15 by injecting urethane through the injection port 21.
' A heat insulating layer 23 is formed between the heat insulating box 12 and the insulating box 12.

In the case of urethane foaming, there is an inlet 2 other than that required for injection.
1 is closed with a cap 24 having a cross-sectional shape or a sealing material, and then urethane is injected, and the injection port 21 into which urethane has been injected is also immediately closed with the cap 24 or the sealing material.

Then, a storage is manufactured by equipping a heat insulating box body 12 with a heat insulating property with a refrigeration device such as a condenser 5, a blower fan, and a compressor.

Next, the case of manufacturing a series model based on the above embodiment will be explained with reference to FIGS. 10 and 11.

Top part 7, 7', bottom part 8.8' of insulation box element 11.11'
, extending from the top 7'', the bottom 8'', the back 9'' and the front 10'' corresponding to the back 9.9' and the front 10.10'',
An intermediate insulation box element 11'' whose height and depth are equal to those of the insulation box element 11.11' is constructed, and the intermediate insulation box element 11'' is interposed between both insulation box elements 11.11'. , as in the above embodiment, each insulation box element body 11.11 is
', 11'' are connected to form a single body, and urethane foam is formed.
A heat insulating box body 12' having heat insulating properties is constructed, a cooling device is provided in the heat insulating box body 12', and storages with different widths are manufactured.

Therefore, by interposing and connecting an arbitrary number of intermediate insulating box elements 11'' between the left and right insulating box elements 11 and 11', it is possible to manufacture insulating boxes 12' having different widths. Therefore, various series of storage machines can be manufactured at low cost.

The width of the intermediate insulation box element 11'' is determined by the series level of the width of each storage in the series.

As described above, according to the insulating box of this invention, in the insulating box that is integrated by joining and connecting two insulating box bodies that are protected from the side, main part, bottom, back, and front, The joint surface of the outer wall of one of the insulation box elements is formed to protrude from the joint surface of the inner wall, and the joint surface of the inner wall of the other insulation box element is formed to protrude from the joint surface of the outer wall. The assembly strength is improved by fixing a block to the inner surface of the protruding wall, fixing a spacer that abuts the block to the inner surface of the other protruding wall, and connecting the block and the spacer with screws. At the same time, the seal is complete and communication between the inside and outside of the refrigerator can be prevented. Furthermore, since the insulation box is divided into two parts, it is easier to mold the outer and inner walls of the insulation box, reducing manufacturing costs. can be reduced.

In addition, by interposing an intermediate insulating box element consisting of a top, bottom, back and front part between the two insulating box elements, and integrating each insulating box element, it is possible to store a series of items with different widths. The manufacturing cost of various types of heat insulating boxes can be reduced.
