Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a refrigerator, and particularly to a refrigerator suitable for improving the strength of a hinge seat.

[Conventional technology]

Commercially available refrigerators can be roughly divided into JP-A-1985-118.
They are classified into two types: those in which the foam insulation material is extended to the partitioning hot wall part, as in No. 66, and those in which it is not. That is, in the former case, the foamed insulation material is placed over the entire partitioned thermal wall when filling the space between the outer box and the inner box with the foamed insulation material, and in the latter case, the partitioned thermal insulation wall is pre-assembled with styrofoam, etc. The space between the outer box and the inner box, excluding the partitioned thermal walls, was filled with in-situ foam insulation material.

[Problem that the invention seeks to solve]

In the case where the above conventional technology is a partitioned thermal wall, the hinge seat that fixes the door hinge is fixed by using the adhesive force of the foam insulation material itself to fix the inner box, the outer box, and the foam insulation material together. or not. The integral (former) type has sufficient hinge seat strength, so even if the hinge that pivots the door is installed, the door will not fall down. wall·
At best, it was only fixed to the inner box, and it was separated from the foam insulation material and the outer box made of iron plates, so there was a problem that sufficient strength could not be obtained.

On the other hand, the former had the problem that it was difficult to form a cold air passage that circulates cold air cooled by a cooler installed in the freezer compartment to the refrigerator compartment. Our goal is to provide a refrigerator with

[Means for solving problems]

The above purpose is to provide a refrigerator equipped with a hinge seat that pivots one end of the door to the front part of the partition thermal wall provided in the inner box to separate the freezer compartment and the refrigerator compartment. This is achieved by passing foam insulation filled with in-situ foam between the outer box and the inner box only in those areas where the insulation is removed.

[Effect]

The hinge seat to which the hinge is fixed is fixed to the partitioning thermal wall, inner box, outer box, etc. through a small amount of foam insulation material filled in the notch, so that even if force is applied to the hinge, the hinge will remain fixed. The door will not move between itself and the hinge seat and cause the door to slide down.

〔Example〕

The details of the present invention will be explained below with reference to an embodiment shown in the drawings.
2 is a refrigerator main body, 2 is a door that closes the front opening, 2a is a freezer compartment door, 2b is a refrigerator compartment door, and 2c is a vegetable compartment door. 3 is an inner box that forms the inside of the refrigerator body 1, and 4 is a partitioning thermal wall that partitions the inside of the refrigerator into a freezer compartment 5 and a refrigerator compartment 6, which are not shown in the figure. This forms a cold air circulation path to the refrigerator compartment 6. Moreover, this partitioning thermal wall 4 is incorporated into the inner box 3 before the foamed-in-place heat insulating material 8 is filled between the inner box 3 and the outer box 7. 9 is a partition thermal wall 4
It is a metal hinge seat attached to the front of the 10 is a door 2a together with other hinges 11, 42, etc.

It is a hinge that pivots 2b rotatably. 14 is a screw for screwing the hinge 10 to the hinge seat 9.

As shown in FIG.
A notch 13 into which the water flows is provided. The foamed heat insulating material 8 filled in this notch 13 is a relatively thin foamed heat insulating layer. The foamed heat insulating material filled in the notch 13 is not only fixed to the partitioned thermal wall 4 and the hinge seat but also fixed to the inner box 3, outer box 7, etc. as one body.

〔Effect of the invention〕

According to the present invention, the strength of the hinge seat is ensured, and the sliding of the door can be minimized. Further, since this reinforcing means does not include any special parts, it is possible to obtain an inexpensive reinforcing structure.
