Description

[Detailed Description of the Invention] The present invention is a device that divides the inside of a refrigerator into a circular inner box! Insert the space between the inner box and the outer box at 8° into the space that divides it into upper and lower chambers. °C partition walls were inserted into the formed support rails to divide the inside of the main body into t lower chambers, but the partition walls that were necessary for this occasion were the left and right walls and the left and right side walls of the inner box. Refrigerator main body Y* that can eliminate the need for sealing material between the rear wall and the sealing material χ between the rear wall of the compartment and the back wall of the inner box, and achieve a strong support structure for the wall. This is what we provide.

Next, the actuality of the present invention will be explained in detail. (1) is a metal outer box with a front opening, and (2) is a synthetic resin inner box with a front opening, which are integrally molded on opposite positions of the circular surfaces of the left and right side walls.
A support rail (3) is formed, and a recess (5) continuous with Wm above the support rail (31) is formed on the inner surface of the dorsal wall, covering almost the entire stomach wall.The inner box (2) faces outward. It may be covered with a fluorocarbon-resistant bag.

The outer box (11) and the circular shaft (21 are the 7 lunges (1 person) and (2 mm) formed by the front opening edge C2, respectively, are combined so that they are in contact with each other, and the upper and lower, left and right, and rear spaces of both boxes are Form a space filled with heat insulating material to form a box body 14) Vllll (6)
The partition wall consists of a container-shaped partition S material (7) with an opening on the top made of synthetic resin, and a partition member (7). Container-shaped partition-cut heat material (marked) and partition-cut heat material (8

In addition, CLR) is the same or slightly smaller than the left and right inner dimensions (Lj) of the inner box (2) at the top of the support rail +31, making it easier to insert the partition wall (6) into the inner box (2). ing.

(9) is a duct member attached to the outer surface of the inner box (2) across the hole (to) aD formed on the top and bottom of the recess (5) in the shape of a circular axis.In this configuration, the outer box (1) and the circular axis A box body (4) is prepared by combining (2) with a filling space for the heat insulating material, and a partition wall (61t- Prepare and insert the partition wall (6) onto the partition member (the engagement stage 11 (70) v support rail 13 of 71) in the backward position C: at the same time.This insertion is slightly L.
It is very easy if i:>Ll, and Ll'
L! Even so, C can be easily achieved by the flexibility of the circular shaft (slight deflection of the left and right side walls of 2I and the partition heat material 18). Therefore, the appropriate relationship between Ll and Ll is Ll≧Lt, but depending on the bending of the circular axis and the degree of flexibility of the partition heat material (8), M may not be supported even if Ll is slightly larger than Ls. Partition g! +6) inserted into the box body (4), the rear part of the partition g1+61 fits into the recess (5) circle, and the rear wall (8B) of the partition g1+61 fits into the recess (5) circle.

The liquid is injected and foamed, and the filling space is filled with the heat insulating material a. The foaming pressure of the heat insulating material 63 caused by this foaming process causes the circular shaft (2) to bend inwardly. In order to receive this, the partitioning heat material (8) is slightly compressed within the range of its flexibility and comes into strong (close contact) with the circular shaft (2).

iiillF study. Also, sufficient contact with the circular shaft (2) can be made on the rear surface of the partition wall (6).

In order to maintain strong adhesion between the partition heat material (8) and the inner box (2), conventionally a long and thin soft sealing material was pasted on the sides and rear of this partition wall (61) to achieve sealing. Comparing to the case where sealing material is not required, the number of manufacturing steps can be reduced.Also, since the circular ring and the partition-cut heating material can be used in a wide area, the C-partitioning heating material can be used as the sealing material for the V-bottle. This means that the conventional
I! After filling the insulation material between the circular shaft and the outer box, it was inserted inside the gate box, so if the pre-distributed material was thickened, it would be difficult to insert the partition wall. 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 a complex structure is required to achieve a sufficient seal.C2 Become. In addition, in the present invention, since the circular shaft and the partition wall are in strong contact with each other, the partition wall can be firmly held, and it can be used to support the partition*t'-cooler or to put heavy objects into the refrigerating gate above the partition wall. C can also be made into a structure that can withstand the load sufficiently.

:be. For this reason, it is easy to insert the partition wall, and the foaming pressure when filling the filling space (bi-foam insulation material) ensures close contact between the inner box and the partition heat material, which is different from the conventional method. Even without the need for a sealing material, a reliable rail structure can be achieved, and the structure can be firmly held in the partition Wt-gate box and can sufficiently withstand supporting heavy objects in the freezer compartment. 1 pltF and rear ev of the partition heating material than the furnace wall and rear wall of the partition member.
If the shape 1111 is slightly protruded, even if the foaming pressure f2 is compressed, the partition member and the inner box will come into contact with each other, preventing excessive hairstyle of the inner box and damage to the partitioning heat material. This enables close contact between the inner box and the inner box over a wider area.
