[Detailed Description of the Invention] [Industrial Application Field] This invention relates to a cooling system consisting of a refrigerator and a refrigeration system installed therein, and particularly to an improvement of the heat insulating wall structure for the cooling chamber of this refrigeration system.

[Conventional technology]

A conventional cooling device will be explained with reference to FIGS. 6 and 7.

In FIG. 6, 1 is a refrigerator having a refrigerator compartment 2 inside, 3 is a freezing device installed in the refrigerator 1,
Compressor 4, radiator 5, this radiator 5 on base plate 17
A first blower 6 and a cooling unit 4 are mounted to blow air to the air. The cooling unit 7 is composed of a cooler 8, a second blower 9, a drain pan 10, and a heat insulating wall 11 that accommodates these. 12 is a cooling chamber formed by the heat insulating wall 11. Reference numeral 13 denotes a fixing member for closely adhering the heat insulating wall 11 to the top panel 15 of the refrigerator 1 via the first gasket 16, and is fixed to the base plate 17 with screws 14. 18 is the top panel 15
The cooling chamber 12 and the refrigerating chamber 2 are in communication with each other. 19 is drain pan 1
This is a ventilation guide provided below the 0.

FIG. 7 is a detailed view of the heat insulating wall 11 shown in FIG. 6, and is drawn with the bottom surface of the heat insulating wall 11 facing upward. That is, the heat insulating wall 11 covers the upper surface of the cooling chamber 12 and the upper surface of the cooling chamber 12.
The sides are integrally formed.

[Problem that the invention attempts to solve]

Because the conventional cooling system is configured as described above, installation work is easy and it is widely used. When replacing the second blower 9), the following problem occurred.

That is, the internal dimensions of refrigerators such as prefabricated refrigerators are generally 1.8 to 2.4 m, and there is little space between the refrigerator and the ceiling of the building. Therefore, the refrigeration equipment and the ceiling of the building are close to each other. Therefore, when the heat insulating wall of a refrigeration system is integrally formed as in the past, there is a problem in that the heat insulating wall cannot be removed and repairs and inspections are difficult.

This invention was made in order to solve the above-mentioned problems, and the object is to obtain a cooling device in which the heat insulating wall forming the cooling chamber can be easily removed.

[Means for solving problems]

The cooling device according to this invention has a cooling chamber that houses a cooler and a blower, and a U-shaped insulating wall that integrally forms the upper surface and both side surfaces of the cooling chamber, and a gasket at both ends of the U-shaped insulating wall. The above objective is achieved by constructing a flat heat insulating wall that is closed by interposing it.

[Effect]

The cooling device according to this invention includes a U-shaped insulating wall that integrally forms the top and both side surfaces of a cooling chamber that houses a cooler and a blower, and a gasket intervening between the open surfaces of both ends of this U-shaped insulating wall. A flat insulating wall to be closed, and a co-coat which is formed slightly smaller than the dimension between the two flat insulating walls and sandwiching the upper wall of the U-shaped insulating wall and both flat insulating walls with the backing plate interposed therebetween. The contact surface between the letter-shaped heat insulating wall and both flat heat insulating walls can be reliably sealed, and each heat insulating wall can be removed laterally.

[Example of idea]

Fig. 1 is a cooling device showing an embodiment of this invention, Fig. 2 is a plan view of Fig. 1, and Fig. 3 is a plan view of Fig. 2.
The AA cross-sectional view and FIG. 4 are the main parts of the BB cross-section in FIG. 2. FIG. 5 shows another embodiment of this invention. In FIGS. 1 to 4, parts that are different from FIG. 6 will be explained. Reference numeral 20 denotes a U-shaped heat insulating wall that integrally forms both sides and the top surface of the cooling chamber 12, and 21 indicates a second gasket 2 at both open ends of the U-shaped heat insulating wall 20.
5 is interposed between them to close the opening surface, and 22 is an L-shaped insulating wall provided straddling both ends of the upper wall of the U-shaped insulating wall 20 and the upper part of both flat insulating walls 21. The backing plate 23 is formed to have a dimension _L2 that is slightly smaller than the dimension _L1 between the two flat heat insulating walls 21 before compressing the second gasket 25, and the backing plate 23 is
This is a U-shaped connector that fixes the U-shaped heat insulating wall 20 and both flat heat insulating walls 21 so as to sandwich the upper wall of the U-shaped heat insulating wall 20 and both flat heat insulating walls 21 with the U-shaped heat insulating wall 20 interposed therebetween. 24 connects the U-shaped connector 23 to the base plate 1
This is a screw for fixing to 7.

In the above configuration, the U-shaped connector 23
As a result, both flat heat insulating walls 21 are pressed against both vertical end surfaces of the U-shaped heat insulating wall 20 via the second gasket 25, and are also pressed against both flat heat insulating walls 21 by the U-shaped connector 23. The L-shaped backing plate 22 presses both flat heat-insulating walls 21 onto both end faces of the upper wall of the U-shaped heat-insulating wall 20 via a second gasket 25.

Therefore, both flat heat insulating walls 21 are brought into close contact with the U-shaped heat insulating wall 20 through the second gasket 25, and are reliably sealed.

Further, when inspecting or repairing the inside of the cooling chamber 12, by removing the U-shaped connector 23, the U-shaped heat insulating wall 20 and both flat heat insulating walls 21 can be removed laterally.

In the above embodiment, the L-shaped backing plate 22 is provided spanning both ends of the upper wall of the U-shaped heat insulating wall 20 and the upper part of both the flat heat insulating walls 21. If it is relatively rigid, it does not need to be attached. In addition, two L-shaped backing plates 22
As shown in FIG. 5, it may be formed into a U-shaped integral body.

[Effect of idea]

As described above, according to this invention, a cooling chamber housing a cooler and a blower is constructed by a U-shaped insulating wall that integrally forms the top surface and both side surfaces, and a gasket at both ends of the U-shaped insulating wall. A U-shaped connecting tool formed by a flat insulating wall that is closed by interposing the above, and formed slightly smaller than the dimension between the two flat insulating walls, and sandwiching the upper wall of the U-shaped insulating wall and both flat insulating walls. As a result, the U-shaped insulating wall and both flat insulating walls are fixed, so the contact surfaces between each insulating wall can be reliably sealed in a simple manner, and the components can be easily sealed during inspection and repair inside the cooling room. By removing the letter-shaped connectors, each heat insulating wall can be removed laterally, which has the practical effect of allowing easy servicing even when there is little space between the refrigeration equipment and the ceiling of the building.
