Description

REFRIGERATOR HAVING SUPPLY STRUCTURE OF COOLING AIR}

The present invention relates to a cold air supply structure of a refrigerator, and more particularly, to a flow path configuration of cold air for balancing the amount of cold air discharged through cold air discharge ports formed on the rear and left and right sides of the refrigerating chamber.

In general, a refrigerator is divided into a freezer compartment for storing an ice making container and a frozen food at a set temperature, and a refrigerating compartment in which a refrigeration object is stored. In the freezer compartment and the refrigerating compartment, cold air converted by a refrigerant circulating in a freezing cycle is provided. Keep it for a long time.

1 to 4 illustrate a cold air supply structure of a conventional refrigerator, FIG. 1 is a sectional front view, FIG. 2 is a sectional view taken along line AA ′ of FIG. 1, FIG. 3 is a sectional view taken along line AA ′ of FIG. 1, and FIG. BB cross section.

As shown, a conventional refrigerator is partitioned into a freezer compartment 2 and a refrigerating compartment 4 by a barrier 5 filled with heat insulating material, and a cooler compartment partitioned by a shroud 12 at the rear side of the freezer compartment 2. (1) and the cold air distribution chamber 15 are formed.

Heat exchange is performed in the evaporator 6 mounted inside the cooler chamber 1 through which a low temperature low pressure refrigerant passes, and a part of the cold air is supplied to the freezing chamber 2 through the shroud 12 by the axial fan 8. The remaining part is freely dropped through the shroud 12 and supplied to the refrigerating chamber 4.

The cold air supply structure to the refrigerating chamber is as follows.

The cold air supplied from the freezing chamber to the refrigerating chamber is sucked into the suction port formed on one side of the lower surface of the shroud 12, passes through the cold air supply passage 31 formed below the suction port, and is formed inside the barrier 5. It is divided into branch flow paths 32 and 33.

A part of the cold air branched toward the left branch passage 32 passes through the rear branch passage 30 installed in the longitudinal direction on the rear surface of the refrigerating chamber, and is discharged through the plurality of rear discharge ports 30a, and part of the cold air flows as it is. It discharges through the left discharge port 32a formed in the left side of 4).

The cold air branched toward the right branch passage 33 is discharged through the right discharge port 33a formed in the right side of the refrigerating chamber 4 in its entirety.

In this way, the discharge ports 32a and 33a for cold air are formed not only on the rear surface of the refrigerating chamber 4 but also on both sides thereof to achieve an even temperature distribution in the refrigerating chamber.

The cold air supplied to the freezer compartment 2 and the refrigerating compartment 4 through the above process becomes relatively high temperature through heat exchange with the food stored therein, and the air at high temperature is formed in the freezer compartment 5 of the barrier 5. It moves back to the evaporator 6 via the return flow path 2a and the refrigerator compartment return flow path 4a.

By the way, in the cold air supply structure of the refrigerator as described above, the cold air flowing out from the cooler chamber 1 is supplied to the freezer compartment and the refrigerating chamber supply passage 31 through the cold air distribution chamber 15 having no separate partition structure. The structure has been pointed out as a problem in that cold air distribution between the freezer compartment and the refrigerating compartment is difficult to be made uniformly, and therefore, it is difficult to form an efficient cold air circulation structure.

SUMMARY OF THE INVENTION An object of the present invention is to provide a refrigerator having a more efficient cold air supply structure, in which cold air distribution to a freezer compartment and a refrigerating compartment is made constant.

The present invention provides a chiller chamber having an evaporator for cooling the air circulating in the refrigerator and a blowing fan for imparting a flow force to the air, in order to achieve the object as described above, the cold air flowing out from the cooler chamber freezer and the refrigerating chamber A refrigerator having a cold air supply structure including a cold air distribution chamber for distributing and guiding a furnace and a supply flow path for supplying cold air discharged from the cold air distribution chamber to the refrigerating chamber, wherein the cold air distribution chamber is divided into a first cold air distribution chamber by a partition wall. And a supply passage configured to supply cold air from the first cold air distribution chamber to the refrigerating chamber, and configured to supply cold air directly from the second cold air distribution chamber through a cold air discharge port to the freezing chamber. A refrigerator having a cold air supply structure is provided.

In addition, the cold air supply structure according to the present invention includes a rear branch passage which is branched from the supply passage connected to the rear discharge port of the refrigerating chamber; A left branch passage branched from the supply passage and connected to a left discharge port of the refrigerating compartment; A right branch passage which is branched from the supply passage and connected to a right outlet of the refrigerating compartment; It is preferable to comprise.

Furthermore, the supply passage, the rear branch passage, the left branch passage and the right branch passage may be formed inside the barrier of the refrigerator.

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

5 to 8 illustrate a cold air supply structure according to the present invention, FIG. 5 is a front sectional view, FIG. 6 is an AA ′ sectional view of FIG. 5, FIG. 7 is an AA ′ sectional view of FIG. 5, and FIG. 8 is of FIG. 5. BB cross section.

As shown, the cold air supply structure according to the present invention is divided into a freezer compartment 2 and a refrigerating compartment 4 by a barrier 5 filled with insulation, and a shroud 12 at the rear side of the freezer compartment 2. It is basically the same as the cold air supply structure of the conventional refrigerator in that the cooler chamber 1 and the cold air distribution chambers 50 and 60 which are partitioned are formed.

However, the cold air distribution chamber is partitioned into the first cold air distribution chamber 50 and the second cold air distribution chamber 60 by the partition wall 70, and the supply passage 40 is separated from the first cold air distribution chamber 50 by the refrigeration chamber ( 4) is formed to supply cold air, which is different from the conventional case in that the freezing chamber 2 is configured to supply cold air directly from the second cold air distribution chamber 60 through the cold air discharge port 15a.

That is, after the cold air flowing out from the cooler chamber 1 by the blower fan 8 is introduced into the two cold air distribution chambers 50 and 60, once separated, the predetermined amount of cold air is respectively distributed in the freezer compartment 2 and the refrigerating compartment. Since it takes the structure supplied to the supply flow path 40, the ratio of cold air distribution to the freezer compartment and the refrigerating compartment by adjusting the volume or position of the two cold air distribution chambers 50, 60 according to the installation position of the partition wall 70. It is possible to adjust it constantly.

In the present embodiment, the case where the cold air distribution chamber is divided up and down by the partition wall 70 is illustrated, but even if the structure is partitioned to the left and right, the basic ratio of the present invention is to constantly adjust the cold air distribution ratio for the freezer compartment and the refrigerating compartment. There is no relationship in achieving the technical idea.

In addition, in this embodiment, although the supply passage 40 is formed along the rear wall of the main body located behind the freezing compartment from the first cold distribution chamber 50, the cold air distribution to the freezing compartment 2 and the refrigerating compartment 4 is performed. Since it is sufficient if it is made independently, it does not necessarily need to take such a structure, and may be formed along the side wall of a main body, etc.

On the other hand, the cold air supply structure according to the present invention is branched from the supply passage 40 and the rear branch passage 30 connected to the rear discharge port 30a of the refrigerating chamber (4); A left branch passage 32 branched from the supply passage 40 and connected to the left discharge port 32a of the refrigerating chamber 4; A right branch passage 33 branched from the supply passage 40 and connected to the right discharge port 33a of the refrigerating chamber 4; It is configured to include.

That is, when the amount of cold air supplied through the supply passage 40 is 1, the amount discharged through the rear discharge port 30 is 1/2, and the amount discharged through the left and right side discharge ports 32 and 33, respectively. Since it can be set to 1/4, the temperature distribution in the refrigerating chamber can be evenly obtained as a result.

In addition, the cold air supply structure as described above may be installed anywhere in the space between the freezer compartment and the refrigerating compartment, but it would be more preferable in terms of practical feasibility to be installed inside the barrier 5 which is a structure generally used conventionally. Seems to be.

The present invention provides a refrigerator having a more efficient cold air supply structure, in which cold air distribution to the freezer compartment and the refrigerating compartment can be made constant.
