Description

Cold air discharge structure of the refrigerator

The present invention relates to a cold air discharge structure of a refrigerator, and more particularly, to a cold air discharge structure of a refrigerator which blocks leakage cold air near an evaporator among cold air discharged into a refrigerator from a cold air circulation passage to discharge the refrigerator into a refrigerator.

The overall cold air circulation structure of the general refrigerator is, as shown in FIG. 1, the cold air cooled from the evaporator 4 installed in the cold air circulation passage 1 behind the freezer compartment 2 is cooled by the fan motor 5. And forced circulation to the refrigerating chamber 3.

That is, the cold air discharged to the discharge port 1a in the freezer compartment 2 is circulated therein and then again evaporated through the suction duct 6a installed in the intermediate compartment 6 partitioning the freezer compartment 2 and the refrigerating compartment 3. (4), while the cold air discharged into the refrigerating chamber 3 is discharged into the refrigerating chamber 3 through the damper 7 and the discharge port 1b, and also the suction duct 6b in the intermediate partition 6 It has a circulation structure which flows into and returns to the evaporator 4.

As shown in FIG. 2, when the cold air discharge structure around the conventional evaporator 4 is described in detail, the cold air generated from the evaporator 4 is stored in the refrigerator 2, 3 (freezer compartment, but the refrigerator compartment) by the fan motor 5. In the case where the evaporator is installed independently, the refrigerating chamber is also included).

In such a conventional refrigerator, the above-mentioned cold air is not discharged entirely through the discharge port 1a formed in the evaporator cover plate 8, and the gap 1c with the heat insulating member 9 provided inside the support plate 8. Part of it leaks. Therefore, in this gap 1c, not only dew condensation caused by leakage of cold air is caused, but also the cooling performance of the refrigerator is lowered as a sufficient inflow of cold air is prevented.

Therefore, the present invention is to solve the above-described problems, the present invention is to block the cold air leaking to the vicinity of the evaporator of the cold air discharged from the cold air circulation passage to return to the inside of the refrigerator to improve the cooling performance of the refrigerator The object is to provide a cold air discharge structure.

The cold air discharge structure of the refrigerator according to the present invention for achieving the above object, an evaporator having an evaporator installed to generate cold air in the cold air circulation passage, and having a cold air discharge port which covers the front surface of the evaporator and communicates with the interior of the refrigerator And a cover plate, a heat insulation member mounted inside the evaporator, and a cold air blocking jaw additionally installed so that cold air does not flow into a gap between the evaporator cover plate and the heat insulation member.

Here, it is preferable to further include an auxiliary discharge port for allowing cold air introduced into the gap to be discharged back into the refrigerator by hitting the blocking jaw around the cold air blocking jaw.

Accordingly, by blocking the cold air leaking out of the cold air discharged into the high temperature near the evaporator and returning it back to the high temperature, not only the loss of cold air is prevented, but also the cooling performance can be further improved.

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

3 is a sectional view showing main parts of a structure of a cold air discharge around an evaporator of a refrigerator according to the present invention and a functional state thereof.

In the figure, reference numeral 30 denotes an evaporator cover plate which covers the evaporator 40 and forms a partition wall between the cold air circulation passage 10 and the inside of the refrigerator 20.

A cold air discharge port 32 is formed in the evaporator cover plate 30, and cold air cutoffs 33 and 34 protrude from the upper and lower portions of the cold air discharge port 32 to form a gap with the heat insulating member 60. 12) to block.

In addition, since the auxiliary discharge holes 35 and 36 are further penetrated and formed in the periphery of the blocking jaws 33 and 34 of the evaporator cover plate 30, the cold air introduced into the gap 12 is returned to the inside of the chamber 20. It is very preferable to be able to return.

Of course, the evaporator 40 which can generate | occur | produce cold air is installed in the cold air circulation passage 10, and the fan motor 50 which can blow the cold air produced | generated here to the inside of the storehouse 20 is mounted.

Here, the interior 20 mainly refers to a freezer compartment, but when the evaporator 40 is installed on each side of the freezer compartment and the refrigerator compartment independently, it means both a freezer compartment and a refrigerator compartment.

In the cold air discharge structure around the evaporator 40 of the refrigerator according to the present invention having such a structure, the cold air generated from the evaporator 40 of the cold air discharge port 62 and the evaporator cover plate 30 of the heat insulating member 60 When forcedly discharged to the inside of the refrigerator 20 through the cold air discharge port 32, even if cold air leaks into the gap 12 formed between the heat insulating member 60 and the evaporator cover plate 30, the cold air shutoff jaw 33 Blocked at 34 and returned as indicated by the arrow, it is discharged secondarily through the auxiliary discharge ports 35 and 36 in the vicinity thereof.

Therefore, the cold air blocking projections 33 and 34 and the auxiliary discharge ports 35 and 36 formed in the evaporator cover plate 40 serve to block leakage of cold air and to discharge it back into the interior of the refrigerator.

As described above, according to the present invention, it is possible to prevent the loss of cold air and further improve the cooling performance by blocking cold air leaking out of the cold air discharged into the air near the evaporator and returning it to the air.

The present invention is not limited to the above-described specific preferred embodiments, and any person having ordinary skill in the art to which the present invention pertains may make various modifications without departing from the gist of the present invention claimed in the claims. Of course, such changes will fall within the scope of the claims.
