Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in a cooler having a structure in which a rear opening of the main body of the cooler is closed by a plastic rear plate attached thereto.

For example, in a refrigerator with a structure in which this type of cooler is installed inside an outer box, since a heat insulating material such as urethane is foamed and filled between the outer box and the cooler, the back plate is attached to the main body of the cooler. Therefore, it is necessary to provide a seal to prevent the heat insulating material from entering the main body of the cooler.

For this reason, in the past, an adhesive tape was adhesively wound around the attachment part of the back plate to the main body of the cooler to seal the attachment part.

However, with the above conventional configuration, the work of wrapping the adhesive tape is troublesome and takes a lot of time, and furthermore, the adhesive tape stretches and comes off from the wrapped part due to the foaming heat when filling the insulation material with foam. Seal is no longer done,
Alternatively, there is a risk that the back plate may be strained and deformed and come off from the part where it is attached to the main body of the cooler, causing it to break.

Furthermore, the adhesive tape needs to have a high adhesive strength, resulting in high cost.

This invention was made in view of the above circumstances, and its purpose (
This makes it possible to seal the attachment part of the back plate to the main body of the cooler extremely easily and in a short time.Moreover, it is possible to seal the part where the back plate is attached to the main body of the cooler very easily and in a short time. To provide a cooler that has no fear of coming off from a part attached to a main body and can be manufactured at low cost.

An embodiment in which the present invention is applied to a refrigerator will be described below based on FIGS. 1 to 5. First, in FIG. 4 is a cooler for a freezer according to the present invention, which is arranged at the upper part of the outer box 1 and has a freezer compartment 5 inside; 6 is an outer box 1; and the inner box 2 and the freezer compartment cooler 4, 7 is a refrigerator compartment cooler installed in the refrigerator compartment 3, and 8 and 9 are the refrigerator compartment 3 and freezer compartment 5, respectively. It is a door that opens and closes.

The specific structure of the freezer compartment cooler 4 will now be described with reference to FIGS. 2 to 5.

That is, 10 has openings (back opening 10a) on the front and back sides.
The main body of the cooler is a rectangular box-shaped cooler having a rear opening 103 (only shown in the figure), and a flange portion 10b oriented outward is integrally formed on the periphery of a rear opening 103.

11 is a substantially rectangular plastic back plate;
This is formed by integrally forming an extending portion 13 having an angular cross section on the outer peripheral edge of the opening of the back plate main body 12 which has a shallow rectangular container shape, so that the outer peripheral surface of the back plate main body 12 and the extending portion 13 A U-shaped groove section 14 is formed between the extension section 13 and a bent piece 16 is integrally formed at the tip of the extension section 13 via a self-hinge section 15.

However, in order to attach the back plate 11 to the back opening 10a of the cooler main body 10, first the back opening 10a is
The outer circumferential surface of the back plate main body 12 is press-fitted into the inner part so that the extending part 13 covers the flange part 10b of the cooler main body 10, and then the bent piece 16 is attached to the self-hinge part 15 as shown in FIG. The tip of the bent piece 16 is brought into airtight contact with the outer peripheral surface of the cooler main body 10 by its restoring force, and the pressed part is bent so as to be folded inward, that is, into the groove 14. Sealing is performed during foam filling of the heat insulating material 6.

In addition, since there is a possibility that the above-mentioned sealing effect may not be obtained sufficiently at the four corners of the back plate 11, at the four corners,
As shown in FIG. 5, the flange portion 10b of the cooler main body 10
A sealing member 17 made of soft foam rubber or the like is interposed between the bent piece 16 and the bent piece 16.

In the above embodiment, bent pieces 16 are also provided at the four corners of the back plate 11.
However, as shown in FIGS. 6 and 7, bent pieces 1 are provided at the four corners of the back plate 11.
6, and a groove located between the outer circumferential surface of the cooler main body 10 located to the left in the figure from the flange part 10b and the crest part 13, or to the right in the diagram from the flange part 10b. The sealing member 17 may be provided within the sealing member 14 .

As explained above, the present invention seals the attachment part of the back plate to the main body of the cooler by an extremely simple and short-time process of simply bending the bent piece integrally formed on the back plate inward. Moreover, since the bent pieces are integrated with the back plate, there is no risk that the bent pieces will come off due to the heat of foaming during foam filling of the insulation material, and there is no risk of the above-mentioned seal becoming insufficient. It is something that never gets put away.

In addition, since the flange of the main body of the cooler acts as a stop for the bent piece of the back plate to be pulled out, even if the back plate is strained and deformed by the foaming heat, the back plate will come off from the part attached to the main body of the cooler. There is no need for a conventional adhesive tape, and it can be manufactured at low cost.
