Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is a refrigerator that divides the inside of a refrigerator into upper and lower chambers by inserting a partition wall into an inner box. Partition walls were inserted into the completed main body using support rails formed on the left and right side walls of the inner box to divide the main body into upper and lower chambers. It is possible to eliminate the need for sealing material between the left and right walls of the inner box and the left and right side walls of the inner box, and between the rear dust of the partition wall and the back wall of the inner box, and a strong support structure for the partition wall can be achieved. It provides the refrigerator itself.

Next, embodiments of the present invention will be described in detail with reference to the drawings.

1 is a metal outer box with a closed front, and 2 is an inner box made of synthetic resin with an open front. Support rails 3 are integrally formed at opposing positions on the inner surfaces of the left and right side walls, and support is provided on the inner surface of the back wall. A recess 5 continuous with the upper wall surface of the rail 3 is formed over substantially the entire width of the back wall.

The inner box 2 may have an outer surface covered with a fluorocarbon-resistant bag. The outer box 1 and the inner box 2 are combined so that the flanges A and 2A, which are formed in green with a closed front, are in contact with each other to form a space filled with heat insulating material between the upper, lower, left, right, and rear walls of both boxes. A box body 4 is configured. Reference numeral 6 denotes partition walls, including a container-shaped partition member 7 with an open top and an open top made of synthetic resin, and a container-shaped partition with a closed top and a foamed heat insulating material such as styrofoam stored in the partition member 7 molded into a predetermined shape. The partition heat material 8 has visibility with some elasticity.

The left and right side walls 8A, 8A and the rear wall 8B of the partitioning heat material 8 extend upward and slightly outward from the left and right side walls 7A, 7A and the rear wall 7B of the partition member 7. Specific examples regarding this include the outer dimension L of the left and right side walls 7A, 7A of the partition member 7, and the outer dimension L of the left and right side walls 8A, 8A of the partition heat material 8.
2, the left and right side walls 7A of the partition member 7,
7A, the left and right side walls 8A, 8A of the partition heat material 8 protrude outward by about 1 to several millimeters, respectively, and the partition heat material 8
The rear wall also protrudes outward from the rear wall 7B of the partition village 7 by about 1 to several millimeters. Further, L is equal to or slightly smaller than the inner dimension L on the left and right sides of the inner wall 2 at the upper part of the support rail 3, making it easy to insert the partition wall 6 into the inner box 2. Reference numeral 7C denotes an engaging stepped portion formed on the left and right sides of the bottom of the partition member 7 and extending forward and backward, and is a portion that is connected to the support rail 3.

A duct member 9 is attached to the outer surface of the inner box 2 across holes 10 and 11 formed in the inner box above and below the recess 5.

In this configuration, a box body 4 is prepared in which an outer box 1 and both boxes 2 are combined with a space filled with the heat insulating material, and a partition wall 6 in which a partitioned heat material 8 is stored in a partition member 7 is prepared. death,
The partition wall 6 is inserted toward the rear with the engaging stepped portion 7C of the partition member 7 placed on the support rail 3.

This insertion is extremely easy if Wakachi et al. >L2;
Further, even if L=L2, it can be easily achieved by making some recesses on the left and right side walls of the inner box 2 and the flexibility of the partition heat material 8. Therefore, the appropriate relationship between L and L is L32L2, but depending on the sagging of the inner box and the degree of maneuverability of the partition heat material 8, L
In some cases, it may be acceptable even if L5 is slightly larger than L5. When the partition wall 6 is inserted into the predetermined position of the box body 4, the partition wall 6
The rear part of the partitioning heat member 8 fits into the recess 5, and the rear wall 8B of the partitioning heat material 8 abuts against the inner surface of the recess 5. After the partition wall 6 is inserted into a predetermined position [in this case, it may be attached to a partition front plate 22, which will be described later, to maintain the predetermined position. ], Filling between the inner box 2 and the outer box 1 with the foaming jig in the foaming process placed in a predetermined location on the outer surface of the outer box 1 and the inner surface of the inner box 3 excluding the partition wall 6. A stock solution of a foamable heat insulating material such as polyurethane is injected into the space and foamed, and the filled space is filled with the heat insulating village 12. Due to the foaming pressure of the heat insulating material 12 in this foaming process, the inner box 2 receives a force that slightly moves it inward, so the partition heat material 8 is slightly compressed within the range of flexibility and tightly adheres to the inner box 2. do. This compression is limited with the inner box 2 resting against the wall around the partition section 7, and the inner box 2 and the L. If the difference is slight, surface contact will occur over a wide range with the left and right side walls 2 of the partition wall 6.
Further, sufficient contact with the inner box 2 can be made even on the rear surface of the partition wall 6. In this way, strong adhesion between the partitioning heat material 8 and the inner box 2 can be maintained, but in the past, sealing was achieved by pasting elongated European sealing members on the side and rear surfaces of the partition wall 6. No sealing material is required, and the number of work steps can be reduced.

In addition, since the inner box and the partition heat material have a wide surface contact, the partition heat material can also serve as a sealing material. This is because in the conventional case, the partition wall was inserted into the inner box after insulating material was filled between the inner box and the outer box, so if the sealing material was too thick, it would be difficult to insert the partition wall. Or,
Since defects such as peeling of the sealing material occur, the seal between the partition wall and the inner box cannot be said to be strong after all, and various complicated structures are required to achieve a sufficient seal. In addition, in the present invention, the inner box and the partition wall are in strong contact with each other, so the partition wall can be firmly held, and even if a cooler is supported on the partition wall or heavy objects are placed in the freezing chamber above the partition wall, the load The structure can be made to withstand sufficiently. In the refrigerator body completed by incorporating the partition wall 6 as described above, a cooler 13 is placed on the partition heat material 8 via a mist receiving plate, and a heat insulating plate 14 is placed on the cooler 13. In this state, a recess 23 is formed on the left and right side walls of the inner box 2 so that the freezer compartment garden slope 15 is placed on the upper surface of this heat insulating plate 14 (this may also be used as a recess above the support rail 3 as shown in the figure). A freezing chamber 16 is formed by inserting the container into the freezer.

17 is a refrigerating room formed below the partition wall 6.

18 is a refrigerator compartment formed below the freezer compartment 6.

18 is a cold air distribution unit provided at the back of the freezer compartment 16, which guides the air cooled by the cooler 13 to the electric blower 19, and a part of the cold air is discharged from the cold air outlet 20 to the freezer compartment above. The remainder is discharged from the duct section 9 through the hole 10 to the refrigerator compartment 17 through the hole 11.

The cooler 13 does not need to be layered on the partition wall 6, and the present invention can also be applied to a structure in which only a cold air passage is formed between the partition wall 6 and the heat insulating plate 14. 22 is a partition front plate attached to the front surface of the partition wall 6 via a heat insulating material 21 so as to span between the flanges on the left and right sides of the outer box 1; The partition wall 6 can be fixed by attaching it before filling the partition wall 12.

As described above, the present invention is such that the partition crab is inserted into a box body in which the inner box and the outer box are combined with a space filled with a heat insulating material, and the space filled with foam is filled with a foamable heat insulating material. In this case, the partitioning thermal material of the partition wall has a dimension relationship that projects slightly outward from the left and right side walls and rear wall of the partition member, and the outer dimensions of the left and right side walls of the partitioning thermal material are equal to those of the inner box. The dimensions are equal to or slightly smaller than the inner dimensions of the left and right side walls of the inner box above the support rail.

For this reason, it is easy to insert the partition wall, and the foaming pressure when filling the filling space with the foam insulation material ensures strong adhesion between the inner box and the partition heat insulation material. A reliable sealing structure can be achieved even without the need for a seal, and the partition wall can be firmly held in the inner box, resulting in a structure that can sufficiently withstand support of heavy objects in the freezing chamber. Furthermore, if the side walls and rear walls of the partitioning heat material are made to protrude slightly from the side walls and rear walls of the partition member of the partition wall, even if the partition heat material is compressed by foaming pressure, the partition member and the inner box will not touch each other. This prevents excessive deformation of the inner box and damage to the partitioning heat shield by contacting the inner box, and allows the side walls of the partition wall and the inner box to be attached over a wider area.
