Description

Defrost water drain device for refrigerator

The present invention relates to a refrigerator, and more particularly, to a defrost water collecting guide of a refrigerator in which a bead shape is formed on a rear wall so that deformation does not occur even in the expansion force of the foam.

The refrigerator is a product designed to keep the inside at a low temperature below a predetermined temperature in order to keep food fresh.

Hereinafter, the configuration of a defrost water container according to the prior art will be described in detail with reference to the drawings.

FIG. 1A is a longitudinal cross-sectional view of a refrigerator including a conventional defrost water container, and FIG. 1B is a cross-sectional view taken along line AA ′ of FIG. 1A.

According to the drawing, a freezing space 4 capable of freezing stored matter is located at the upper part of the refrigerator, and an evaporator 10 is installed inside the rear side 6 of the freezing space 4. And a defrost water container 12 is installed below the evaporator 10. The defrost water container 12 is to be installed in a space formed on one side of the rear side 14 as shown in the figure. That is, a space is formed at one side of the rear side of the heat insulating material constituting the barrier 14 and the defrost water container 12 is inserted into the space.

In addition, as shown in the figure, the defrost water container 12 is installed in contact with the inner case 8a of the refrigerator. That is, the defrost water container 12 is installed adjacent to the foam foam forming the rear wall 22 of the refrigerator to be described below. In addition, the defrosting water container 12 is composed of four side surfaces 12 ', and the side surface 12' of the four side surfaces 12 'which are in contact with the rear wall 22 of the refrigerator is formed in the horizontal direction long Has the shape of. Hereinafter, the side surface 12 'of the defrost water container 12 in contact with the rear wall 22 of the refrigerator is referred to as the rear surface 12b.

The defrost water container 12 has a shape in which the cross section thereof narrows downward. That is, the upper portion of the rear surface 12b of the defrost container 12 is formed wider laterally but narrower toward the lower side. This means that the foam foam and the rear surface 12b are in wide contact with the rear surface 12b of the defrosting water container 12.

The defrost water container 12 serves to guide the defrost water to the bottom of the refrigerator. Therefore, a discharge port 18a for guiding the defrost water to a defrost water evaporator (not shown) provided in the lower portion of the refrigerator is formed below the defrost water container 12.

In addition, the defrost water container 12 is generally made of a synthetic resin and is manufactured in an injection type. Therefore, while the defrosting water container 12 has an advantage of long life due to the nature of the synthetic resin material, it is pointed out that it is easily bent due to weak external pressure.

On the other hand, the rear wall 22 of the refrigerator is formed by supplying and foaming a foaming liquid between the outer case 8b and the inner case 8a. Generally as said foam liquid, a polyurethane foam liquid is used. And, the foam foam serves to insulate the inside of the refrigerator from the outside.

However, in the foaming process, the specific volume of the foaming liquid is increased through the foaming process, so that the specific volume increased in the foaming process is the outer case 8b, the inner case 8a, and the rear surface of the defrost water container 12 of the refrigerator. 12b) acts as a pressure.

Therefore, in order to prevent the inside of the conventional defrosting water container, as shown in the drawing, the wooden jig 2 is installed inside the defrosting water container 12 before the foaming liquid is supplied, and when the curing of the foaming liquid is completed. I'm using the removal method. However, the wood jig 2 alone does not adequately prevent the pressure on the defrosting water container 12, and many defective products are produced in the production process. In the drawing, 18 means a defrost water pipe, 25 means a refrigerated space, and 2 means a wooden jig.

Hereinafter, the operation of the conventional defrosting water container installed in the refrigerator will be described in detail with reference to the drawings.

Frost formed on the surface of the evaporator 10 of the refrigerator falls into the defrost water container 12 in the form of a liquid or solid phase, and the defrost water container 12 serves to guide this to the lower pipe 18. .

Installation of the defrost water container 12, which serves as described above, is installed in the space formed inside the barrier 14 after inserting the barrier 14 into the inner case 8a. It is assembled in the form of inserting the defrost water container (12). In addition, the outer case 8b and the inner case 8a of the refrigerator are fixed to each other, and the foam is supplied to the space formed between the outer case 8b and the inner case 8a to be filled.

At this time, the volume expansion pressure P generated in the foaming process of the foaming liquid reaches the inner case 8a and the outer case 8b. However, the inner case (8a) and the outer case (8b) is made of a material having a strength that can withstand the pressure, but is made of an insulating material of the barrier 14 and the synthetic resin installed inside the barrier 14 made of a heat insulating material In the case of the water container 12, the phenomenon of bending B occurs in the downward direction on FIG. 1B without being able to withstand the pressure P. FIG.

To prevent this, the wood jig 2 is inserted into the defrost water container 12 as shown in FIG. 1B before the foaming liquid is supplied between the outer case 8b and the inner case 8a of the refrigerator. . And the wooden jig (2) is to be removed after maintaining the shape of the defrost water container (12).

However, the following problems are pointed out in the shape of the conventional defrosting water container.

First, the conventional defrosting water container 12 has a shape of the defrost water container because it does not absorb the foaming pressure generated in the process of foaming the foam liquid supplied between the outer case 8b and the inner case 8a of the refrigerator. The phenomenon that the rear surface 12b of (12) is bent occurs.

Second, since the wood jig 2 must be used separately to support the shape of the defrost water container 12 against the pressure P generated in the foaming process, a manufacturing process of inserting and removing the wood jig 2 is necessary. In addition, since the wooden jig (2) must be purchased separately, a loss of cost occurs.

Third, the defrost water pipe 18 defrosts the defrost water and ice pieces falling from the evaporator 10 because the defrost water container 12 bends the rear surface 12b of the defrost water container 12 due to the foaming pressure. It is not easy to guide. This is a factor that lowers the performance of the refrigerator.

Therefore, an object of the present invention for solving the above problems is as follows.

First, to provide a defrosting water container capable of withstanding the foaming pressure generated in the process of foaming the foaming liquid supplied between the outer case and the inner case of the refrigerator.

And, to provide a defrost water container capable of withstanding the foaming pressure without using a wooden jig.
