Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an inner box of a storage which is constructed by connecting a plurality of unit inner boxes.

[0002]

2. Description of the Related Art In recent years, for example, refrigerators having refrigerators and refrigerators having two chambers arranged side by side have been provided.

In this case, the two chambers are generally
It is formed by partitioning the inside of one large inner box into two by a partition member.

Also, as a different one, there is one in which the inner box is vacuum-formed into a shape having two chambers from the beginning.

Further, there is also one in which the two chambers are constituted by different unit inner boxes, and the unit inner boxes are connected by a connecting member.

[0006]

Among the above-mentioned conventional ones, in the one in which the inside of one large inner box is partitioned by the partition member, the partition member is large and the cost is high, and
The assembly was troublesome, and the partition member was not filled with the in-situ foaming heat insulating material, and the rigidity of the box body was lacking.

In addition, in the case where the inner box is formed by vacuum forming into a shape having two chambers, the forming cannot be performed unless the material thickness of the inner box is increased. Since the thickness of the flange remains, the degree of fitting with the outer box is different from other models, and there is a problem that they cannot be shared.

Further, in the case where the two chambers are constituted by different unit inner boxes and the unit inner boxes are joined by the joining member, the joining member is exclusively required, which also increases the cost, and There has been a problem that a dedicated work is required to join the unit inner boxes by the joining member, and the number of assembling steps is large.

The present invention has been made in view of the above circumstances. Therefore, the object thereof is low cost, easy assembling, and sufficient rigidity as a box body is obtained. It is an object of the present invention to provide an excellent inner box of a storage cabinet that can be commonly used.

[0010]

In order to achieve the above object, an inner box of a storage according to the present invention comprises a plurality of unit inner boxes connected to each other. Is attached to the front plate of the partition and is joined by the front plate of the partition.

[0011]

According to the above means, a plurality of necessary chambers are obtained by connecting a plurality of unit inner boxes with a partition front plate. In this one, the front partition plates are used for connecting the unit inner boxes. Since it can be used, a conventional member dedicated to joining is unnecessary, and naturally, a member dedicated to conventional partitioning is also unnecessary, and further, the joining and assembling of the unit inner box can be performed together with the mounting of the partition front plate. In addition, an in-situ foaming heat insulating material can be filled between the joined unit inner boxes, and a thick material is not required for each unit inner box.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment in which the present invention is applied to an inner box of a refrigerator will be described below with reference to the drawings.

First, FIG. 2 shows a cabinet 1 for the entire refrigerator.
In the upper part, the refrigerator compartment 2 and the ice making / ice storage compartment 3 are shown.
And a freezer compartment 4 having a lower part are arranged side by side. Of these, the refrigerating chamber 2 is formed by the first unit inner box 5, and the freezing chamber 4 including the ice making / ice storage chamber 3 is formed by the second unit inner box 6
It is formed by.

The first unit inner box 5 and the second unit inner box 6 are also as shown in FIG. 3, and each has a flange portion 7, 8 provided on one side of the opening edge portion for coupling with each other. The other three sides are provided with flange portions 10 and 11 for coupling with the outer box 9 (see FIG. 2).

On the other hand, the front partition plate 12 has a vertically long strip shape, and coupling grooves 13 and 14 are formed on both sides of the front partition plate 12 by bending them into an S-shape and an anti-S-shape, respectively.

With this structure, as shown in FIG. 1, a dew-proof pipe 15 is attached to the connecting grooves 13 and 14 of the front partition plate 12, and a sealing material 16 is attached on the dew-proof pipe 15. , 6 are assembled by press-fitting the flange portions 7 and 8 into the coupling grooves 13 and 14, respectively, and thus the unit inner boxes 5 and 6 are coupled by the partition front plate 12.

Both unit inner boxes 5 and 6 after connection are connected to the outer box 9 by the flange portions 10 and 11, and are connected to the outer box 9 and between the unit inner boxes 5 and 6 on site. It is filled with a foamed heat insulating material (for example, foamed polyurethane) 17.

As described above, in this structure, both the first and second unit inner boxes 5, 6 are assembled to the partition front plate 12 and are joined by the partition front plate 12, whereby the refrigerating chamber 2 is provided. And the freezing room 3 including the ice making / ice storage room 4 can be formed side by side.

According to this structure, however, since the above-mentioned two chambers can be formed by the unit inner boxes 5 and 6 individually, a partition member unlike the conventional one is not required, and further, the front partition plate 12 is used as the unit inner box 5. Since it can be used as it is for the connection of 6 and 6, even a connecting member is not required for exclusive use, and the cost can be reduced. or,
Since the front partition plate 12 also serves as the connecting member in this manner, the unit inner boxes 5, 6 can be connected and assembled together with the mounting of the front partition plate 12, and the number of assembling steps can be reduced.

Further, the in-situ foaming heat insulating material 17 can be filled between the unit inner boxes 5 and 6 connected by the front partition plate 12, so that the rigidity of the box body can be sufficiently obtained. .

Since the inner unit boxes 5 and 6 can be formed individually, a thick material is not required, and the cost can be reduced by this. Further, in this case, since the material thickness can be normally held, the degree of fitting with the outer box 9 can be made similar to that of other models, and the commonization can be achieved.

The present invention can be broadly applied to general storage inner boxes such as an inner box of a refrigerator and an inner box of a normal temperature storage in addition to the inner box of a refrigerator. It can be implemented by appropriately changing it.

[0023]

As is clear from the above description, the inner box of the storage according to the present invention is constructed by combining a plurality of unit inner boxes, and the plurality of unit inner boxes are divided into front plates. It is characterized in that it is assembled to and joined by the front plate, whereby the cost is low and the assembly is easy,
Further, it has an excellent effect that the rigidity as a box body can be sufficiently obtained and the common use with other models can be desired.
