Description

[Detailed description of the invention] This invention relates to the improvement of boxes for refrigerators and the like.

The box mentioned above generally has a foam insulation material filled between the outer box and the inner box, and a machine room with an open back is formed at the bottom of such a box. has been done.

Conventionally, as this type of box body, one in which the lower part of the back plate of the outer box is bent in a side cross section into an inverted U-shape to form the earthen wall, front wall, and bottom plate of the machine room is known.

However, this box has the disadvantage that the rear plate has a large area, is heavy, and the material cost is high.

This idea forms only the bottom plate of the machine room with a folded piece that is cut and bent inward from the back plate of the outer box, and the hole formed by the bending of the folded piece is inserted into the hole. By fitting a nearly box-shaped sheet that is missing at least a portion of the box body or the bottom of the machine room, the drawbacks of the conventional ones mentioned above can be overcome, and a strong machine room that can withstand the weight of a compressor, etc. can be created. The purpose is to provide boxes for refrigerators, etc.

An embodiment of this invention will be described below with reference to the drawings.

In FIGS. 1 and 2, reference numeral 1 denotes a box body of a refrigerator, and this box body 1 includes a bottom wall 19 and both side walls 3 which are integrally formed by bending a steel plate, and a main plate 12. A space is formed between the inner box 17 and the inner surface of the outer box 2 in the outer box 2, which is constituted by a back plate 4 that covers the back opening of the main plate 12, a top table (not shown) that covers the upper opening of the main plate 12, etc. A heat insulating material 16 such as urethane foam is installed between the inner box 17 and the outer box 2.
It is made up of foam filling.

Reference numeral 5 denotes a machine room formed at the bottom of the back of the refrigerator box 1 in which a compressor 6 and the like are installed, which will be described in detail later.

7 is a condenser fixed to the outer surface of the back plate 4 of the outer box 2 with a fixture (not shown).

As shown in FIG. 3, the back plate 4 has a substantially inverted concave-shaped notch 8 at its lower part, and a portion surrounded by the notch 8 along a broken-line elongated hole 9 located below the notch 8. The bent piece 10 is cut and bent almost horizontally toward the inside of the refrigerator, and the bottom plate of the machine room 5 is formed over the entire width of the back plate 4.

A protruding piece 11 for locking the front part of the compressor 6 is cut and raised on the bent piece 10 before the bent piece 10 is bent, and is made to stand upright above the bent piece 10 by bending the bent piece 10. .

As shown in Figs. 1, 2, and 4,
is in contact with the lower edge of the machine chamber 5 on the outer surface of the back plate 4 and is fixed below it with screws, and the protruding piece 11 is mounted on the base plate 13.
Correspondingly, the rear locking protrusion 14 of the compressor 6 is erected.

A sheet molded product 15 with an open back is fitted into a hole 20 (see FIG. 2) formed by cutting and raising the bent piece 10 of the back plate 4.
The wall surface of the machine room 5 is formed together with the bent piece 10.

As shown in FIG. 5, the sheet molded product 15 has a trapezoidal box shape made of a vacuum-formed plastic sheet or a folded cardboard product, and is bent into a notch 18 provided in the bottom wall. The locking projecting pieces 11 of the pieces 10 are engaged to project above the sheet molded product 15, and the flange 15a protrudingly formed on the outer periphery of the open end of the molded product 15 is connected to the hole 20 of the back plate 4. The sheet molded product 1 is supported on the peripheral edge of
5, and the notch 18 and the locking protrusion 1
1 prevents the sheet molded product from shifting.

The heat insulating material 16 is connected to the bottom wall 19 of the outer box 2 and the bent piece 1.
The space between the inner box 17 and the sheet molded product 15 is also filled.

In this embodiment, a box-shaped sheet molded product 15 having a bottom wall is used, but this molded product may be one that lacks part or all of the bottom wall.

That is, it may be any material that forms at least the side wall, front wall, and earth wall of the machine room 5 recessed on the inside of the back plate 4.

Further, the compressor 6 is fixed onto the bending piece 10 and the base plate 13 by appropriate means using the protruding pieces 11, 14.

Note that this invention is not limited to refrigerators, and can be applied to boxes of items equipped with a refrigeration cycle, such as freezers.

As explained above, the box body according to this invention has a bent piece 10 formed by cutting and raising the lower part of the back plate 4 of the outer box 2 and bending it toward the inside of the refrigerator.
A recess is formed on the inside of the back plate 4 by a simple sheet molded product such as a vacuum molded plastic sheet or a folded cardboard molded product fitted into the hole 20 formed by cutting and raising the bent piece 10. The bent piece 1 constitutes the wall of the machine room 5 where
0 is placed only on the bottom of the machine room 5, the development area of the back plate of the box body is smaller than that of the conventional case described above, i.e., the back plate material only needs to be small, resulting in a lighter weight and improved structure. The machine room 5 can be configured easily and inexpensively, and
The folded piece 10 is placed on the bottom and the compressor 6 is installed on it, and by filling the space between the bent piece 10 and the bottom wall of the outer box 2 with a heat insulating material 16, the compressor Even if a heavy object such as No. 6 is placed on it, it can be made strong enough to withstand the weight.
