DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a heat insulating box formed by assembling a base panel, a roof panel, and a rear panel and used for a prefabricated refrigerator, freezer, and the like. The present invention relates to a heat-insulating box capable of easily and quickly mounting a partition panel with a small number of parts.

[0002]

2. Description of the Related Art Conventionally, various types of heat-insulating boxes for use in prefabricated refrigerators, freezers, and the like have been proposed. In such a heat-insulating box, a partition panel is provided to divide the inside of the box. For example, the partition panel is fixed inside the heat insulating box by the method described below. Here, a method of fixing the partition panel performed in the conventional heat insulating box will be described with reference to FIGS. FIG. 6 is a perspective view partially showing a mounting structure of a partition panel in a conventional heat insulating box, and FIG. 7 is a cross-sectional view of the mounting structure of the partition panel.

[0003] In FIG. 6, a rear panel 101 is fixed to an inner end (right side in FIG. 6) of a base panel 100 to form a heat insulating box.
00, rear panel 101 and roof panel (not shown)
On the inner wall of the panel, there is a partition panel 10 for dividing the inside of the heat insulating box.
2 is fixed. In order to fix the partition panel 103, first, a pair of metal “L” -shaped parts are separated from each other at predetermined portions of the base panel 100, the rear panel 101 and the roof panel by a width corresponding to the width of the partition panel 103. The mounting plate 104 is attached with screws 105,
The partition panel 103 is arranged between the mounting plates 104, and each mounting plate 104 is separated by the screws 106 from the partition panel 1.
03. Thereby, the partition panel 103
Is fixed over the base panel 100, the rear panel 101 and the roof panel.

As shown in FIG. 7, a base panel 100, a rear panel 101, a roof panel, and a pair of side panels (not shown in FIGS. 6 and 7) constituting a heat insulating box are made of metal as shown in FIG. A heat insulating material 109 is filled between the exterior facing material 107 and the interior facing material 108, and a screw 105 corresponding to a horizontal portion of the “L” -shaped mounting plate 104 inside the interior facing material 108. A screw plate 110 for reinforcing the fastening is provided. Further, the partition panel 103 is formed by filling a heat insulating material 112 between a pair of similar face materials 111, and a screw plate 113 for reinforcing the fastening with the screw 106 corresponding to a vertical portion of the mounting plate 104. It is interposed.

[0005]

However, in the conventional mounting structure of the partition panel 103, a pair of "L" -shaped mounting plates 104 are mounted on the base panel 100, the rear panel 101, and the roof panel by screws 105. However, there is a problem that the number of parts increases, which leads to an increase in cost, and that the mounting operation using various tools becomes complicated. As a result, it takes time to assemble the heat insulating box.

Further, in the above-mentioned mounting structure, since the partition panel 103 is basically fastened and fixed by screws using the mounting plate 104, it is necessary to reinforce the fastening and fixing of the mounting plate 104 by the screws 105. The screw plate 110 needs to be interposed in the base panel 100.
It is necessary to interpose a screw plate 113 for reinforcing the fastening and fixing of the partition panel 103 in the partition panel 103. Therefore, also in this respect, the structure is complicated and the cost is increased.

Further, in the mounting structure, the base panel 1
00, the interior panel material 108 in the rear panel 101 and the roof panel is formed of a single continuous metal plate, and is therefore continuous on both sides of the partition panel 103. When the temperature difference is significantly different, heat conduction occurs via the interior facing material 108, and the temperature in each room becomes unstable.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned conventional problems, and it is possible to easily and quickly mount a partition panel for partitioning the inside of a heat insulating box with a small number of parts. It is another object of the present invention to provide a heat insulating box capable of preventing heat from being generated on both sides of the partition panel and stabilizing the temperature of each of the compartments defined by the partition panel.

[0009]

According to a first aspect of the present invention, there is provided a heat insulating box formed by assembling a base panel, a roof panel, a rear panel, and a pair of side panels. In a heat insulating box having a partition panel fixed to a rear panel and partitioning the inside, a first screw hole which is provided inside the base panel, the roof panel and the rear panel where the partition panel is arranged and is exposed to the outside is provided. The partition panel comprising: a formed first block member; and a second block member internally provided at an edge of the partition panel corresponding to the first block member and having a second screw hole formed therein. Is
The second screw hole of the second block material and the first screw hole of the first block
The screw member is fastened to the base panel, the roof panel and the rear panel in a state where the screw member is aligned with the screw hole.

In the heat insulating box, the first screw holes of the first block material provided in the base panel, the roof panel and the rear panel are aligned with the second screw holes of the second block material provided in the partition panel. By fastening the screw member in this state, the partition panel is fixed to the base panel, the roof panel, and the rear panel. This makes it possible to easily and quickly mount the partition panel that partitions the inside of the heat insulating box with a small number of components.

According to a second aspect of the present invention, in the heat insulating box of the first aspect, the base panel, the roof panel and the rear panel are filled with a heat insulating material between an inner wall material and an outer wall material. The inner wall material is divided at a position where the partition panel is disposed, leaving a predetermined gap.
In such a heat insulating box, heat conduction is prevented from being generated on both sides of the partition panel based on the fact that the inner wall materials of the base panel, the roof panel, and the rear panel are divided with a predetermined gap at the position where the partition panel is disposed. As a result, the temperature of each room partitioned by the partition panel can be stabilized.
