Description

An apparatus for fixing the rear panel of refrigerator.

The present invention relates to a rear panel fixing device of a refrigerator, and more specifically, to prevent the liquid leakage from being generated in a process of forming after urethane foaming while the rear panel of the refrigerator is fastened, thereby preventing occurrence of liquid leakage. It relates to a rear panel fixing device of a refrigerator so that a separate work process due to liquid leakage can be eliminated.

In general, a refrigerator is used to maintain a food or beverage that requires refrigeration or freezing in a refrigerated or frozen state, and is required to efficiently manage cold air to maintain and preserve an object stored in a cold state. In order to keep food or beverages refrigerated or frozen in the refrigerator, a freezing cycle should be constructed.

The refrigeration cycle of the refrigerator is a compressor of the machine room formed in the lower rear of the refrigerator as a low heat source, and compresses the low boiling point refrigerant saturated steam having a high heat source to high pressure and flows it to the condenser. The latent heat of evaporation from the high-temperature and high-pressure refrigerant is released to the high heat source outside the refrigerator, causing a phase change into liquid refrigerant gas, and the liquid refrigerant gas is throttled to low temperature and low pressure through the expansion valve, Flows into.

On the other hand, the refrigerant gas of the low temperature and low pressure in the cooler absorbs latent heat from the low heat source inside the refrigerator in the liquid phase, causing a phase change to the refrigerant gas in a saturated steam state, and then entering the compressor again to form a refrigeration cycle.

By going through the freezing cycle as described above, the inside of the refrigerator is continuously supplied with cold air to have a freezing effect.

Referring to the configuration of the refrigerator for freezing and refrigerating using the freezing cycle as described above, a freezer compartment and a refrigerating compartment, which are partitioned by a trimmer plate, are formed at the upper and lower sides of the cabinet, and the freezer compartment and the refrigerating compartment are formed by respective doors. It is configured to open and close, each of the plurality of pockets for storing food, etc. are formed on the inner surface of each door.

The rear panel is fixed to the rear of the cabinet, such as a table board installed on the upper surface.

In the refrigerating chamber, a plurality of shelves for fastening food and the like are fastened, and at the lower end thereof, a vegetable chamber for storing vegetables and the like is provided.

The refrigerator configured as described above is to continuously supply the cold air generated by the freezing cycle into the freezer compartment and the refrigerating compartment, thereby maintaining food or beverage in the refrigerator or frozen state.

3 and 4, the rear panel installed as the rear side of the cabinet is described in more detail with reference to FIGS. 3 and 4. The insertion grooves 92 formed at both sides of the rear side of the cabinet 90 as shown in FIG. Both ends of the rear panel 80 are inserted, and an upper end thereof is disposed between the rear outer circumferential surface 70a of the table board 70, which is installed as the upper surface of the cabinet 90, and a plurality of engaging pieces 72 formed therein. Inserted as in to fix the rear panel (80).

However, the conventional rear panel 80 is fixed in this way, after the urethane foaming, the top of the rear panel 80 is inserted into the rear of the table board 70 due to the expansion of the urethane in the process of forming the table board A problem arises that a liquid leak occurs while being separated between the rear outer circumferential surface 70a of the 70 and the plurality of engaging pieces 72 formed inwardly thereof.

In this way, a problem arises that a separate work process that needs to be removed due to a liquid leak occurs.

Accordingly, the present invention is designed to solve the problems described above, and is configured to prevent the liquid leakage from occurring during the molding process after urethane foam in the state in which the rear panel of the refrigerator is fastened, thereby preventing the occurrence of liquid leakage. The purpose is to be able to delete the extra work fixed by the liquid gland.

In order to achieve the above object, the present invention provides a plurality of hook pieces formed at the rear outer circumferential surface of the table board and both ends of the rear panel of the refrigerator which are inserted into the insertion grooves formed at both sides of the rear of the cabinet, and the top of which is installed as the upper surface of the cabinet. In inserting and fastening therebetween, each fastening protrusion is formed on a locking piece formed to the rear of the table board, and a fastening hole is formed at a position corresponding to the fastening protrusion at the upper end of the rear panel to be coupled to each other. It is done.

Hereinafter, a preferred embodiment of the present invention by the accompanying drawings as follows.

Figure 1 is a schematic perspective view of the main portion showing a state in which the subject innovation is installed, Figure 2 is a schematic sectional view of the main portion of the combined state according to Figure 1, the insertion grooves formed on both sides of the rear of the cabinet 90 of the refrigerator (100) Both ends of the rear panel 80 are coupled to the upper surface of the rear panel 80 between the rear outer circumferential surface 70a of the table board 70 installed on the upper surface of the cabinet 90 and a plurality of locking pieces 72 formed therein. Inserted, but each engaging projection 10 is formed on the engaging piece 72 and the fastening hole 20 is formed at a position corresponding to the engaging projection 10 at the top of the rear panel 80 to be mutually coupled It is a figure which shows that it is fastened.

Referring to the operation and effects of the present invention configured as described above in more detail by the accompanying drawings, Figures 1 and 2 as follows.

Insertion grooves 92 are formed on both sides of the rear side of the cabinet 90, and both ends of the rear panel 80 are coupled to the insertion grooves 92, and an upper end of the rear panel 80 is a cabinet 90. Is inserted between the rear outer circumferential surface 70a of the table board 70 installed in the upper surface of the plurality of engaging pieces 72 formed therein, and each of the engaging pieces 72 is formed with each fastening protrusion 10. A fastening hole 20 is formed at a position corresponding to the fastening protrusion 10 at an upper end of the rear panel 80, so that an upper end of the rear panel 80 is engaged with the rear outer circumferential surface 70a of the table board 70. The fastening hole 20 of the rear panel 80 is coupled and fastened with the fastening protrusion 10 formed on the fastening piece 72 while being inserted between the pieces 72.

As described above, the fastening hole 20 formed at the upper end of the rear panel 80 is inserted into and fixed to the fastening protrusion 10 of the locking piece 72 formed to the rear of the table board 70, thereby forming a conventional urethane after foaming. Due to the expansion of the urethane in the process it is possible to prevent the upper end of the rear panel 80 is separated between the rear outer peripheral surface 70a of the table board 70 and the engaging piece 72.

In this way, the upper end of the rear panel 80 is not separated, it is possible to prevent the liquid leakage due to the separation.

As described above, by fastening and fixing the top of the rear panel installed to the rear of the cabinet of the refrigerator so as not to be detached, it is a useful design that can prevent the leakage of fluid generated by the upper part from being removed, thereby eliminating the additional work fixing.

Although the present invention has been described with reference to one embodiment shown in the drawings, this is merely exemplary, and it will be understood by those skilled in the art that various modifications and equivalent other embodiments are possible.

Therefore, the true technical protection scope of the present invention should be defined only by the attached utility model registration claims.
