Description

Refrigerator {REFRIGERATOR}

The present invention relates to a refrigerator, and more particularly, to a refrigerator capable of expanding the effective contents of a refrigerator compartment by improving an arrangement structure of a freezer compartment evaporator and a refrigerator compartment evaporator.

In general, a refrigerator is a device for supplying cold air generated in a cooling device to an internal storage compartment so that the storage compartment maintains a low temperature state, so that the freshness of the stored storage can be maintained for a long time.

In the refrigerator, as illustrated in FIG. 1, the storage compartment inside the main body 1 is divided into an upper freezing compartment 3 and a lower refrigerating compartment 4 through an intermediate wall 2, and a freezing compartment 3 and a refrigerating compartment. The open front of (4) is provided with the doors 5 and 6 which can be opened and closed. In addition, inside the rear of the freezer compartment 3 and the refrigerating compartment 4, the freezer compartment evaporator 7 and the refrigerator compartment evaporator 8 are provided to generate cold air, and in front of these evaporators 7 and 8, a freezer compartment ( 3) and an inner plate 11, 12 for partitioning the space inside the refrigerating chamber 4 and the space in which the evaporators 7, 8 are installed, and forming the cold air flow passages 9, 10. In addition, above the freezer compartment evaporator 7 and the refrigerator compartment evaporator 8, cold air circulation fans 13 and 14 for circulation of cold air are respectively provided. In addition, the inner plates 11 and 12 have a plurality of cold air discharge ports 11a and 12a through which cold air circulated is discharged into the freezer compartment 3 and the refrigerating compartment 4, and cold air inside the freezer compartment 3 and the refrigerating compartment 4. In addition, cold air suction ports 11b and 15 suctioned toward the evaporators 7 and 8 are formed.

In the refrigerator having such a configuration, since the evaporators 7 and 8 and the cold air circulation fans 13 and 14 are respectively installed in the freezer compartment 3 and the refrigerating compartment 4, the temperature change of the freezer compartment 3 and the refrigerating compartment 4 is different. By controlling the temperature of the freezing compartment (3) and the refrigerating compartment (4) through the operation of the cold air circulation fan (13, 14) separately controlled according to the optimum freezing and refrigeration conditions can be maintained.

However, the refrigerator having such a configuration has a drawback in that the effective contents of the refrigerating compartment 4 are reduced due to the refrigerating compartment evaporator 8 and the cold air circulation fan 14 separately installed inside the refrigerating compartment 3. That is, since the inner plate 12 of the refrigerating compartment 4 protrudes to the inside of the refrigerating compartment 4 by the evaporator 8 and the cold air circulation fan 14 for the refrigerating compartment, there is a problem that the internal volume of the refrigerating compartment 4 becomes small. .

The present invention is to solve such a problem, an object of the present invention by placing the refrigerating compartment evaporator and the cold air circulation fan in the free space behind the freezer compartment, the internal volume of the refrigerating compartment without increasing the internal volume of the freezer compartment will be that much. One would be to provide a refrigerator.

It features.

In addition, the present invention is characterized in that the space in which the freezer compartment evaporator is installed and the refrigerator compartment evaporator is installed by partition walls.

In another aspect, the present invention is characterized in that the cold air supply passage and the cold air return flow path is formed in the intermediate wall partitioning the freezer compartment and the refrigerating compartment, the space in which the refrigerating chamber evaporator is installed and the refrigerating compartment communicate.

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

In the refrigerator according to the present invention, as shown in FIGS. 2, 3, and 5, the storage compartment inside the main body 20 is divided into an upper freezing compartment 22 and a lower refrigerating compartment 23 through an intermediate wall 21. The freezing chamber 22 and the refrigerating chamber door 25 for opening and closing the freezing chamber 22 and the refrigerating chamber 23 are respectively installed.

And inside the rear of the freezer compartment 22, a freezer compartment evaporator 26 and a refrigerator compartment evaporator 27 for supplying cold air into the freezer compartment 22 and the refrigerating compartment 23 are provided. In addition, a freezer cold air circulation fan 28 for circulating the cold air generated in the freezer compartment evaporator 26 into the freezer compartment 22 is installed at the upper part of the freezer compartment evaporator 26, and is provided at the top of the refrigerator compartment evaporator 27. A cold air circulation fan 29 for a refrigerating compartment for circulating the cold air generated by the practical evaporator 27 into the refrigerating compartment 23 is installed. That is, in the present invention, the refrigerating chamber evaporator and the refrigerating chamber circulation fan which are installed at the rear of the refrigerating chamber are arranged at the rear of the freezing chamber 22 so that the internal volume of the refrigerating chamber 23 can be increased. To this end, the freezer compartment evaporator 26 is disposed to one side, and the space A in which the freezer compartment evaporator 26 is installed and the space B in which the refrigerator compartment evaporator 27 is installed are defined by the partition wall 40. It is divided into left and right. (See FIG. 2 and FIG. 5)

In addition, the freezer compartment evaporator 26 and the refrigerating compartment evaporator 27 are provided in front of the freezer compartment inner plate 30 which partitions the spaces A and B in which these evaporators are installed and the internal space of the freezer compartment 22. At this time, the freezer compartment inner plate 30 is provided with a freezer compartment cold air supply passage 31 so that the cold air generated in the freezer compartment evaporator 26 can be supplied into the freezer compartment 22. In addition, the freezing chamber inner plate 30 is formed by dispersing a plurality of cold air outlet 32 in communication with the cold air supply passage 31 and the freezing chamber 22, the lower portion of the inner plate 30 in the freezer compartment 22 The cold air suction port 33 through which air is sucked back toward the freezer evaporator 26 is formed. In addition, as shown in FIG. 5, the freezer compartment cold air supply passage 31 extends toward the front side of the space B in which the refrigerating compartment evaporator 27 is installed so that the cold air discharged is evenly supplied to the entire freezer compartment 22. do.

In addition, one side of the refrigerating chamber evaporator 27, as shown in Fig. 2, 4, 5, the refrigerating chamber cold air supply passage so that the cold air generated in the refrigerating chamber evaporator 27 can be supplied into the refrigerating chamber 23 ( 35) is formed. The refrigerating chamber cold air supply passage 35 extends toward the refrigerating chamber 23 through the intermediate wall 21, branched into two branches at the rear of the refrigerating chamber 23, and extends downwardly. In addition, the plurality of cold air outlets 36 in which the cold air supply passage 35 communicates with the inside of the refrigerating compartment 23 and the cold air supply passage 35 for the refrigerating compartment so that cold air may be discharged into the refrigerating compartment 23 inside the cold air supply passage 35 behind the refrigerating compartment 23. Is formed. In the intermediate wall 21, a refrigerating compartment cold air return passage 37 is formed to allow the air inside the refrigerating compartment 23 to be sucked back to the evaporator 27 for the refrigerating compartment. That is, the present invention is provided so that the cold air passages 31 and 33 for the freezer compartment and the cold air passages 35 and 37 for the refrigerator compartment are separately provided so that the cold air circulation of the freezer compartment 22 and the refrigerating compartment 23 is performed separately.
