Abstract

The present invention discloses a structure for fixing a drain pipe of a refrigerator. Disclosed is a drainage pipe of a refrigerator having a locking jaw fixed to be locked after insertion into an insertion hole of a machine room separator plate. It is formed in predetermined length in the longitudinal direction so that it may not be separated by the injection pressure of the heat insulating material injected between outer insides.

Therefore, even if the insulating material is foamed between the inner and outer trauma can not only be firmly fixed so that the drain pipe is not easily separated, but also the inside of the tube is not blocked by the insulating foam.

Description

Drain pipe fixing structure of the refrigerator

The present invention relates to a structure for fixing a drain pipe of a refrigerator, and more particularly, to a structure for fixing a drain pipe of a refrigerator such that when the heat insulating material is foamed between the inner and outer wounds, the drain pipe is separated and the inside thereof is not blocked by the insulating foam.

1 is a cross-sectional view showing a structure for fixing a drain pipe of a conventional refrigerator.

In Fig. 1, a heat insulating material 3, such as a polyurethane stock solution, is foam-filled between the inner and outer wounds 1 and 2 of the refrigerator, and is produced from an evaporator or a freezer not shown in the wall made of the heat insulating material 3. A drain pipe 4 for discharging the defrost water is embedded.

The lower end of the drain pipe 4 is inserted into the insertion hole 6a formed in the separator plate 6 of the machine room 5 and then drawn out toward the evaporating dish 7.

Here, the lower end of the drain pipe 4 is provided with a locking jaw (4b), the locking jaw (4b) is locked around the insertion hole (6a) of the machine room separator 6 is not flowing the drain pipe (4) Is fixed.

The drain pipe 4 of the conventional refrigerator fixed in such a structure is an evaporating dish 7 inside the machine room 5 through a connecting pipe connecting the refrigerating chamber 8 to the defrost water generated in the freezer compartment (not shown). To be discharged.

However, when the lower end of the drain pipe 4 is assembled and fixed, the locking structure 4b of the drain pipe 4 is easily detached from the insertion hole 6a of the machine room separator 6, so that the fixing structure is fragile. When (1) (2) is foamed injection of the liquid insulating material (3) there is a problem that the insulating foam liquid 3 is introduced through the bottom drain port 4a of the drain pipe 4 to block the inside of the pipe.

Therefore, the technical problem to be solved by the present invention, that is, the purpose of the present invention is to fix the drain pipe of the refrigerator so that the inside of the pipe is not blocked by the insulating foam when the foam is insulated between the inner, outer wound is fixed. To provide structure.

The drain pipe fixing structure of the refrigerator according to the present invention for achieving the above object, in the drain pipe of the refrigerator having a locking jaw is fixed after the insertion into the insertion hole of the machine room separator plate, the lower outlet in the lower portion of the locking jaw of the drain pipe It is characterized in that a plurality of incision grooves are formed at a predetermined depth in the longitudinal direction so as not to be separated by the injection pressure of the insulating material injected between the inner, outer wound at a predetermined interval in the circumferential direction.

Here, it is preferable that the diameter D1 of the upper part of the drain pipe is smaller than the diameter D2 of the lower part based on the locking step.

Hereinafter, preferred embodiments of the present invention will be described in more detail with reference to the accompanying drawings.

2 is a cross-sectional view showing a structure for fixing a drain pipe of the refrigerator according to the present invention. And, Figure 3 is an enlarged cross-sectional view of the main part of the present invention, Figure 4 is a rear view of the drain pipe shown in FIG.

In the drawing, in the drawing, reference numeral 40 denotes a drain pipe, which is drawn out to discharge defrost water generated from an evaporator or a freezing chamber not shown.

The drain pipe 40 is buried in a wall filled with a heat insulator 30, such as a polyurethane liquid, which is foam-injected between the inner and outer surfaces 10 and 20 of the refrigerator, and the drain pipe 40 is The lower end extends into a machine room 50 in which components of a refrigeration cycle, such as a compressor 52 or a condenser (not shown), are installed.

That is, the lower discharge port 42 of the drain pipe 40 is located at the upper portion of the evaporating dish 54 installed to be withdrawn from the inside of the machine room 50 to the outside.

A locking jaw 44 is provided at the lower side of the drain pipe 40, and the locking jaw 44 is locked around the insertion hole 62 of the machine room separator 60.

In particular, in the present embodiment, as shown in Figure 3, the plurality of incisions in the circumferential direction at predetermined intervals in the circumferential direction between the lower assembling portion of the drain pipe 40, that is, the lower portion of the locking jaw 44 The groove 46 is cut in the longitudinal direction.

Here, the incision groove 46, as shown in Figure 4, is preferably provided with an inverted triangle shape on the outer surface of the drain pipe 40 to be cut to a predetermined depth.

In addition, as shown in another embodiment of FIG. 5, a rectangular cutout 46 may be cut to a predetermined depth on the inner surface of the drain pipe 40.

Moreover, if the diameter D1 of the upper part of the drain pipe 40 is smaller than the diameter D2 of the lower part of the drain pipe 40 based on the locking projection 44, the drain pipe 40 may be formed by the elastic force caused by the cutout groove 46. Since the lower end is easily retracted into the insertion hole 62 of the machine room separator 60 and then re-expanded, the lower end part is expanded again so that the drain pipe 40 can be firmly fixed.

The drain pipe 40 of the refrigerator according to the present invention, which is fixed in such a structure, is provided with its elasticity by the incision groove 46 at the lower end thereof, so that when it is inserted into the insertion hole 62 of the machine room separator 60 first, Can be easily retracted.

Thereafter, after the assembly is completed and the locking jaw 44 of the drain pipe 40 is fixed around the insertion hole 62 of the separator 60, it is returned to its original position by the elastic relaxation action of the cutting groove 46. As it is expanded, it does not fall easily.

Therefore, even when the injection pressure is significantly received when the heat insulating material 30 is injected between the inner and outer wounds 10 and 20, the drain pipe 40 is not separated from the machine room separator 60.

According to the present invention described above, even if the heat insulating material is foamed between the inner and outer wounds, not only can the drain pipe be securely fixed so as not to be easily separated, but also the inside of the pipe is not blocked by the insulating foam.

While the present invention has shown and described specific preferred embodiments, the present invention is not limited to the above-described embodiments and various modifications may be made by those skilled in the art without departing from the scope of the present invention. And modifications are of course possible.
