As shown in the drawing, the storage space formed inside the cabinet 12 of the Kimchi refrigerator 10 is formed by the barrier 14 formed horizontally inside the cabinet 12 and the upper storage chamber 16 and the lower storage chamber ( 18). In addition, the trays 16a and 18a drawn out in the drawer type are respectively installed in the upper and lower storage chambers 16 and 18, respectively.
[12] A heat exchange chamber 22 having a predetermined space is formed at the rear of the upper storage chamber 16 of the cabinet 12, and inside the upper storage chamber 16 and the lower storage chamber 18 inside the heat exchange chamber 22. An evaporator 24 is installed to heat the air to generate cold air. In addition, above the evaporator 24, an axial fan 26 is provided as a blower fan for supplying the cold air heat-exchanged in the evaporator 24 to the upper storage chamber 16 and the lower storage chamber 18.
[13] The axial fan 26 is installed in the cabinet 12 in a direction in which the rotation axis thereof becomes horizontal toward the front of the cabinet 12. And the cool air supplied to the axial fan 26 from the evaporator 24 provided below the axial fan 26 by the characteristic of the axial fan 26, the center of rotation of the axial fan 26 Direction, ie, toward the upper reservoir 16.
[14] Meanwhile, a discharge port 22a is formed in front of the heat exchange chamber 22. As described above, a part of the cold air flowing from the axial fan 26 passes into the upper storage chamber 16 through the discharge port 22a. The remaining cold air moves downward of the storage chamber 20 and is supplied to the lower storage chamber 18.
[15] The barrier 14 is provided with a cold air duct 28 for supplying cold air to the lower storage chamber 18 with a portion of the cold air flowing from the axial fan 26. A discharge port 28a for discharging cold air into the lower storage chamber 18 is formed at an end of the lower storage chamber 18 side of the cold air duct 28.
[16] However, the kimchi refrigerator according to the prior art having such a configuration has the following problems.
[17] The conventional Kimchi refrigerator 10 has a heat exchange chamber having an evaporator 24 for supplying cold air to the upper storage chamber 16 and the lower storage chamber 18 and an axial fan 26 at the rear of the upper storage chamber 16. 22) is installed. Therefore, the storage capacity of the upper storage chamber 16 is relatively smaller than the lower storage chamber 18, and further the overall storage capacity of the kimchi refrigerator 10 is reduced.
[18] The cold air generated in the evaporator 24 formed behind the upper storage chamber 16 is supplied to the lower storage chamber 18 by the cold air duct 28 formed in the barrier 14. There is a risk of loss of cold air.
[19] An object of the present invention is to improve the above-mentioned conventional problems, to provide a kimchi refrigerator that can reduce the loss of storage capacity.
[20] Another object of the present invention is to provide a kimchi refrigerator that can prevent the loss of cold air during the supply of cold air.

[21] According to the present invention for achieving the above object, the present invention partitions the storage space of the refrigerator into the upper and lower storage chambers, the barriers each having a plurality of discharge ports formed on the upper and lower surfaces; An evaporator installed inside the barrier and generating cold air by heat exchange with a refrigerant; And a transverse fan installed inside the barrier in a direction in which the rotating shaft is horizontal, and supplying cold air heat-exchanged in the evaporator to the upper and lower storage chambers.
[22] In this embodiment, the evaporator is installed in the rear of the barrier, the cross flow fan is installed in front of the evaporator. The crossflow fan is formed of a sirocco fan.
[23] In the Kimchi refrigerator according to the present invention, the evaporator and the sirocco fan are not installed in a separate heat exchange chamber formed at the rear of the upper storage chamber, but are installed inside the barrier, thereby reducing the storage capacity of the kimchi refrigerator. There is an advantage that can be prevented. And since the cold air is directly supplied to the upper storage chamber and the lower storage chamber by the sirocco fan, there is an advantage that can prevent the loss of cold air in the supply process.
[24] Hereinafter, exemplary embodiments of the present invention as described above will be described in detail with reference to the accompanying drawings.
[25] Figure 3 shows a preferred embodiment of the kimchi refrigerator according to the present invention. As shown in the drawing, the storage space inside the cabinet 32 of the kimchi refrigerator 30 is formed by the barrier 34 horizontally formed inside the cabinet 30 and the upper storage chamber 36 and the lower storage chamber 38. It is divided into In addition, the trays 36a and 38a drawn out in the drawers are installed in the upper and lower storage chambers 36 and 38, respectively.
[26] Meanwhile, the barrier 34 extends forward from the rear surface of the cabinet 32, and a predetermined space is formed in the barrier 34 to install the evaporator 44 and the sirocco fan 46.
[27] The evaporator 44 installed inside the barrier 34 heats the air in the upper storage chamber 36 and the lower storage chamber 38 with the refrigerant circulating in the refrigeration cycle to generate cold air. The evaporator 44 is installed at the rear of the barrier 34 to transfer the heat exchanged cold air to the sirocco fan 46 installed at the front thereof.
[28] On the other hand, the sirocco fan 46 installed in front of the evaporator 44 serves to supply the cold air heat exchanged in the evaporator 44 to the upper storage chamber 36 and the lower storage chamber 38. The sirocco fan 46 is a kind of crossflow fan, and is installed in the barrier 34 in a direction in which the rotation axis thereof becomes horizontal.
[29] Therefore, the cold air heat-exchanged in the evaporator 44 flows in the rotational axis direction from the rear of the sirocco fan 46, and passes through the sirocco fan 46 while the centrifugal direction of the sirocco fan 46, that is, the cabinet ( 32) flows up and down. In this embodiment, a sirocco fan 46 is used to supply air flowing from the evaporator 44 to the upper storage chamber 36 and the lower storage chamber 38, but is not necessarily limited thereto. Of course, it can also be applied.
[30] As described above, a plurality of discharge holes 34a are respectively provided on the upper and lower surfaces of the barrier 34 to supply the cool air flowing up and down of the cabinet 32 by the sirocco fan 46 to the upper and lower storage chambers 36 and 38. ) Is formed. Therefore, the cool air flowing from the sirocco fan 46 is discharged through the discharge port 34a of the barrier 34 to be supplied to the upper storage chamber 36 and the lower storage chamber 38.
[31] At this time, since the sirocco fan 46 uniformly flows cold air in the centrifugal direction, the amount of cold air supplied to the upper storage chamber 36 and the lower storage chamber 38 is the same. In addition, since cold air is directly supplied from the sirocco fan 46 to the upper storage chamber 36 and the lower storage chamber 38 through the discharge hole 34a, the cold air is supplied to the upper storage chamber 36 or the lower storage chamber 38. It is possible to prevent the loss of cold air in the process.
[32] It describes the circulation process of the cold air in the kimchi refrigerator according to the present invention having such a configuration.
[33] First, the cold air heat-exchanged with the refrigerant in the evaporator 44 installed inside the barrier 34 of the kimchi refrigerator 30 is installed in a direction in which the rotation axis thereof becomes horizontal in front of the evaporator 44. Will flow into the rear of the. In addition, the sirocco fan 46 rotates by the driving force transmitted from the driving means (not shown), thereby flowing the cold air introduced from the evaporator 44.
[34] However, the cold air introduced into the sirocco fan 46 flows in the centrifugal direction of the sirocco fan 46, that is, up and down of the cabinet 32 while passing through the sirocco fan 46, which is a cross flow fan. In this way, the cool air flowing from the sirocco fan 46 is supplied to the upper storage chamber 36 and the lower storage chamber 38 through discharge holes 34a formed on the upper and lower surfaces of the barrier 34.
[35] In addition, the cold air supplied to the upper storage chamber 36 and the lower storage chamber 38 exchanges heat with the food being stored while circulating inside the upper storage chamber 36 and the lower storage chamber 38. In addition, the return duct (not shown) formed in the upper storage chamber 36 and the lower storage chamber 38 is introduced into the evaporator to exchange heat.
[36] According to the present invention as described above, it can be seen that the basic technical idea is to install an evaporator and a blowing fan installed in the rear heat exchange chamber of the upper storage chamber in the barrier, and to form the blowing fan as a sirocco fan.
[37] Within the scope of the basic technical idea of the present invention, many modifications are possible to those skilled in the art, and the scope of the present invention should be interpreted based on the appended claims. will be.
[38] In the illustrated embodiment, only the case where the kimchi refrigerator is applied to the drawer type kimchi refrigerator has been described, but may be applied to other kimchi refrigerator, for example, a top door type kimchi refrigerator, it can be applied to a general refrigerator as well. to be.
[39] As described in detail above, the kimchi refrigerator according to the present invention is not installed in the heat exchange chamber in which the evaporator and the sirocco fan are formed at the rear of the upper storage chamber, but is installed inside the barrier, thereby preventing the loss of the storage capacity of the kimchi refrigerator. have.
[40] In addition, since the direct cooling air is supplied not only to the upper storage chamber but also to the lower storage chamber by the sirocco fan installed in the direction in which the rotating shaft is horizontal on the barrier, cold air during the supply process can be prevented.
