JP2000337760A - Reinforcing structure for refrigerator housing - Google Patents

Abstract

PROBLEM TO BE SOLVED: To prevent tilting of a refrigerator housing or lowering of a door by providing a reinforcing member where the regions being applied with a load, e.g. the hinge of a door, and the like, are integrated continuously along the front side at the front flange part of the refrigerator housing. SOLUTION: Side plates 1, an inner box 3, baffle plates 4, and reinforcing members are tightened by means of screws 7. The reinforcing member is a U-shaped flat plate and provided between the front flange part of the opposite side plates 1 and a top plate 2 and the front flange part of the inner box 3, or on the inside of the front flange part of the inner box 3 while being laid thereon and three front flange parts are tightened by means of the screws 7. The reinforcing member can limit a moment being applied to the door hinge of a refrigerator using minimum reinforcement. According to the structure, the refrigerator housing can be reduced in weight while preventing it from tilting or preventing the door from lowering.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an efficient reinforcing method in consideration of the weight and deformation of a refrigerator housing.

[0002]

2. Description of the Related Art Conventionally, a method of reinforcing a front flange of a refrigerator housing is, for example, as described in JP-A-8-75344, in which a corner of the front flange of the refrigerator housing is reinforced by a joining member. It is.

[0003]

According to the above-mentioned prior art, for example, in the case of a refrigerator having a single-opening door 32 as shown in FIG. There is a problem that the refrigerator housing 31 is tilted due to the application of force and that the box falls down, and that the door 32 is tilted down. In addition, the box of this refrigerator case fell,
In order to prevent the door from falling, a reinforcing member is attached. However, there is a problem that an improper reinforcing structure increases the weight of the refrigerator housing.

[0004] It is an object of the present invention to provide a reinforcing means for efficiently suppressing the box and door of the refrigerator case from falling down while taking into account the increase in the weight of the refrigerator case.

[0005]

In order to achieve the above object, in a refrigerator housing according to the present invention, an area to which a load such as a door hinge is applied along a surface of a front flange portion of the refrigerator housing. A reinforcing material that is continuously integrated (including welded joints) is provided.

That is, the reinforcing means for attaining the above object is to reinforce each component (side plate, top plate, floor plate, partition plate, partition box, etc.) of the refrigerator housing along the surface of the front flange portion. Because of the material, a housing structure that is resistant to lateral loads and efficiently suppresses the falling of the box can be obtained. In addition, since the load region that causes the box to fall or the door to fall is continuously integrated, a highly rigid housing structure can be obtained.

[0007]

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 shows a first embodiment for realizing the present invention. 1 is a side plate, 2 is a top plate, 3 is an inner box, 4 is foam insulation, 5 is a partition plate, 6 is a reinforcing material, and 7 is a side plate 1, a top plate 2, an inner box 3, a partition plate 4, and a reinforcing material. 5 shows a screw for fastening the components. The reinforcing member 6 is a U-shaped flat plate (a structure in which three flat plates are joined by welding may be used). The reinforcing member 6 includes a front flange portion of both side plates 1 and the top plate 2 and a front flange portion of the inner box 3. It is arranged between or inside the front flanges of the inner box 3, and the three front flanges are fastened with screws 7. This reinforcing material 6 uses minimum reinforcement,
The moment applied to the hinge 34 of the refrigerator door can be suppressed.

FIG. 2 shows a second embodiment for realizing the present invention. 1 is a side plate, 2 is a top plate, 3 is an inner box, 4 is foam insulation, 5 is a partition plate, 6 is a reinforcing material, and 7 is a side plate 1, a top plate 2, an inner box 3, a partition plate 4, and a reinforcing material. 5 shows a screw for fastening between components. The reinforcing member 6 is a square-shaped flat plate (a structure in which four flat plates are joined by welding may be used). The reinforcing member 6 includes a front flange portion of both side plates 1 and the top plate 2 and a front flange portion of the inner box 3. It is arranged between or inside the front flanges of the inner box 3, and the three front flanges are fastened with screws 7. This reinforcing member 6 is more resilient than the reinforcing member of FIG.
The moment applied to the hinge 34 of the refrigerator door can be largely suppressed.

[0010]

By using the reinforcing means of the present invention, it is possible to reduce the weight of the refrigerator housing while suppressing the fall of the box and the door of the refrigerator housing.
