Description

[Detailed description of the invention] [Industrial application field] This invention relates to a partition that partitions two or more rooms with different temperatures, such as a refrigerator-freezer, and in particular, two or more compartments with different temperatures, such as a freezer compartment and a refrigerator compartment. This invention relates to a partition structure between cooling chambers with different temperatures.

[Conventional technology]

Conventionally, refrigerators such as Mitsubishi Refrigerator MR-
The outline will be explained based on FIG. 6, which is a sectional view of the structure of the 3125V internal partition, and FIG. 7, which is an example of a low-temperature corner attached below the internal partition.

The partition 5 that separates the freezer compartment 3 and the refrigerator compartment 4 has an upper surface 6 and a lower surface 7 made of synthetic resin, and a duct A8 that forms the freezer compartment suction air passage 10 between them.
and polymerizes with the duct A8 to form the refrigerator compartment suction ventilation path 1
1 and a duct B9. In addition, a low-temperature corner 1 is provided below the lower surface 7 of the partition.
9 is disposed, and the front surface of the low temperature corner 19 is provided with a lid 20 that rotates around the left and right upper sides as pivots.

Next, the operation will be explained.

As mentioned above, the inner partition 5 is composed of the upper surface 6 and the lower surface 7 of the inner partition, and the ducts A8 and B9, which form the suction ventilation passages for the freezer compartment and the refrigerator compartment, respectively. 3. It plays the role of insulating the refrigerator compartment 4 and sealing the cold air. By the way, when forming the inner box 2 by vacuum forming, the inner partition 5 is formed by setting the inner box 5 at a predetermined position and molding it integrally. A box is formed by filling the hollow portion formed by both with urethane, and during vacuum forming and urethane filling, large pressure and high heat are applied to the sides and back of the partition 5.

[Problem that the invention attempts to solve]

Since the conventional partition structure is configured as described above, the pressure and high heat applied during vacuum forming and urethane filling may cause variations in the partition structure as shown in Figure 7. The center part of the lower surface 7 bulges downward as shown by the dashed line, and the gap between the upper side of the lid 20 that covers the front surface of the low-temperature corner 19 provided at the lower part of the partition is reduced, which improves the design and the rotation of the lid. It had become something defective.

This idea was made to solve the above-mentioned problems, and is a relatively simple method that allows the bulge of the lower surface 7 of the partition to withstand pressure and high heat during vacuum forming and urethane filling. It provides:

[Means for solving problems]

The partition structure according to this invention is such that the lower surface of the partition is fastened to ducts A and B with screws or the like so that it can withstand the pressure and high heat applied during vacuum forming of the inner box and urethane filling.

[Effect]

In this invention, the boss extending upward from the lower surface of the partition is formed by polymerizing ducts A and B to insulate the surrounding area, and is flush with the bottom surface of the recess of duct A, and is made of washer molded from synthetic resin or the like. are fastened with screws. The lower surface of the partition maintains the strength of ducts A and B, and can withstand pressure and high heat during vacuum forming and urethane filling.

Furthermore, a heat insulating spacer as a separate member is interposed in the recessed portion of the duct A to prevent heat conduction from the upper surface of the partition.

〔Example〕

Hereinafter, one embodiment of this invention will be explained with reference to the drawings. In Figs. 4 and 5, 1 and 2 are the outer box and inner box of the refrigerator, and the partition 5 that separates the freezer compartment 3 and the refrigerator compartment 4. have. In FIGS. 1 and 2, the partition 5 is constructed by polymerizing a synthetic resin partition top surface 6, a partition bottom surface 7, and a duct A8 and a duct B9 formed of a heat insulating material such as styrofoam between them. It consists of Further, a boss 12 extending upward is integrally formed in the center of the lower surface 7 of the inner partition, and holes corresponding to the boss 12 are provided in the ducts A and B, respectively, and a recess 1 provided in the duct A8.
The tip of the boss is flush with the bottom surface of 3. Also, a washer 14 molded of synthetic resin or the like is used as an interposition that is fitted into the recess 13 and fixed to the boss 12 with a screw 15, and a spacer 16 molded from styrofoam is fitted into the recess space after the screw is fastened. This prevents heat conduction from the upper surface 6 of the partition. The partition 5 constructed in this way has a cold air suction port 10 for the freezer compartment at the upper front front side, and a cold air suction port 11 for the refrigerator compartment at the bottom, which are heat-sealed.

Since the partition 5 is configured as described above,
First, the duct B9 is placed on the lower surface 7 of the inner partition by passing the hole of the duct B through the boss 12 integrally provided on the lower surface 7 of the middle partition, and then the concave portion 13 of the duct A8 is overlapped with the duct B9. The bosses 12 of the lower surface 7 of the inner partition are stacked on the bottom so that they are flush with each other. The duct A8, the duct B9, and the partition lower surface 7 are fastened to the boss 12 hole of the recess 13 with the screw 15 via the washer 14. Thereafter, after fitting the heat insulating spacer 16 into the recess 13, the partition upper surfaces 6 are overlapped to form the partition 5. When forming the inner box, this partition 5 is set at a predetermined position that separates the freezer compartment 3 and the refrigerator compartment 4, and is integrally formed by vacuum forming to form the inner box. Furthermore, this inner box 2 is inserted into the outer box 1, and a hollow portion formed by both is filled with a foamed urethane stock solution to form a box body.

When forming the inner box 2 by this vacuum forming,
In addition, the effects of pressure and high heat generated when urethane is filled between the inner box 2 and the outer box 1 are applied to both sides and the back of the partition 5. However, the lower surface 7 of the partition is
It is screwed to duct A8 and duct B9,
The structure is designed to withstand this pressure and high heat.

In the above embodiment, the lower surface 7 of the inner partition is connected to the duct A8 and the duct B9 with screws, but in another embodiment, as shown in FIG. It has a structure in which it is fastened with each other's claws.

First, an arrow-shaped claw 17 is located below the top surface 6 of the partition.
A pair of hook-shaped claws 18 extend upward from the lower surface 7 of the inner partition so as to face the arrow-shaped claws 17 on the upper surface 6 of the inner partition, and penetrate through the duct A8 and the duct B9. They are configured to fit into each other.

[Effect of idea]

As described above, according to this invention, the inner box is formed by vacuum forming by firmly fastening the central part of the lower surface 7 of the inner partition to the heat insulating materials of the ducts A, duct B, etc. with screws or the like via washer. The bulge in the middle part of the lower surface 7 of the partition due to the pressure and high heat caused by filling the hollow parts of the inner and outer boxes with the urethane solution is eliminated, and the low-temperature corner installed in the ceiling of the refrigerator compartment 4 and the low-temperature corner This has great effects, such as not hindering the rotation of the lid and maintaining a constant gap over the entire width of the lid.
