Referring to FIG. 2, a freezing compartment cold air generating chamber 300 is provided at the rear of the freezing compartment 100 to receive the freezing compartment evaporator 320 and generate cold air. The freezer compartment cold air generating chamber 300 is shielded by the freezer compartment evaporator cover 310. The freezer compartment duct 110 extends upward and downward in an upper side of the freezer compartment evaporator cover 310. Therefore, the cold air generated by the freezer compartment evaporator 320 moves into the freezer compartment 100 through the freezer compartment duct 110.

In detail, the freezer compartment evaporator 320 is provided inside the freezer compartment cold air production chamber 300 to generate cold air by exchanging heat with a refrigerant. Above the freezer compartment evaporator 320, a freezer compartment blower fan 120 is provided to smoothly discharge the generated cold air into the freezer compartment 100.

In the freezer compartment duct 110, a freezer compartment cold air outlet 111 through which cold air passes is formed. A plurality of freezer compartment cold air outlets 111 may be provided to smoothly discharge the cold air, and may be provided at the same height as or around the freezer compartment blower fan 120.

In this case, when the freezer compartment evaporator cover 310 is formed to cover the upper surface of the freezer compartment evaporator 320, a freezer compartment cold air hole 312 is formed in the freezer compartment evaporator cover to allow cold air to move to the freezer compartment duct 110. It may be formed on the upper surface of 310.

In addition, a freezer compartment cold air inlet 311 is provided below the freezer compartment duct 110 so that cold air circulating in the freezer compartment 100 may flow back to the freezer compartment evaporator 320.

Through such a configuration, the cold air generated by the freezer compartment evaporator 320 is discharged into the freezer compartment 100 through the freezer compartment cold air outlet 111. Then, after cooling the food stored in the freezer compartment 100 is moved to the freezer compartment evaporator 320 again through the freezer compartment cold air suction port 311.

That is, cold air is discharged forward from the upper rear of the freezing compartment 100, and the discharged cold air is sucked backward from the lower front of the freezing compartment 100 after circulating the freezing compartment 100.

3 is a cross-sectional view taken along line II-II 'of FIG. 2.

Referring to FIG. 3, the refrigerator 1 is divided into the freezing compartment 100 and the refrigerating compartment 200 by the barrier 400. In addition, the refrigerator compartment evaporator 520 for cooling the refrigerator compartment 200 is provided separately from the freezer compartment evaporator 320 on the side of the refrigerator compartment side of the barrier 400.

In detail, the side of the refrigerator compartment side of the barrier 400 is provided with an accommodating part 410 which is recessed to a predetermined depth so that a part of the refrigerator compartment evaporator 520 may be accommodated. That is, the depth of the receiving portion 410 is less than or equal to the thickness of the refrigerator compartment evaporator 520. The accommodating part 410 is shielded by the refrigerating compartment evaporator cover 510. In addition, the refrigerating compartment evaporator 520 is provided in the refrigerating compartment cold air generating chamber 500 defined as a space formed by the accommodating part 410 and the refrigerating compartment evaporator cover 510. When the refrigerator compartment door 20 is opened by the evaporator cover 510, the refrigerator compartment evaporator 520 is not exposed to the outside.

Like the freezer compartment evaporator 520, the refrigerator compartment evaporator 520 generates cold air through heat exchange between a refrigerant and air, but the refrigerator compartment evaporator 520 is operated independently of the freezer compartment evaporator 320, and thus the refrigerator compartment 200. Depending on the conditions of) can produce the required cold air. In detail, the refrigerant circulating in the refrigerator 1 is divided into the freezing compartment evaporator 320 and the refrigerating compartment evaporator 520, respectively, such that the control unit (not shown) controls the operation of the refrigerator 1 in the freezing compartment ( 100) and cold air may be independently supplied to the refrigerating chamber 200.

As described above, since the refrigerating compartment evaporator 520 is provided on the side surface of the barrier 400, the length of the front and rear directions of the storage space of the refrigerating compartment 200 is increased. Therefore, the food storage volume inside the refrigerating chamber 200 is increased.

In addition, since the accommodating part 410 is provided so that a part of the refrigerating compartment evaporator 520 is accommodated in the barrier 400, the storage volume of the refrigerating compartment 200 may be further increased.

In addition, by limiting the recessed depth of the accommodating part 410 such that only a part of the refrigerating compartment evaporator 520 may be accommodated, it is possible to prevent the thermal insulation performance of the barrier 400 from being lowered. In detail, the barrier 400 is filled with a foam liquid for thermal insulation. In this case, when the accommodating part 410 is formed to accommodate the entire refrigerating compartment evaporator 520 or the refrigerating compartment evaporator 520 is formed inside the barrier 400 at all, the thickness of the barrier 400 is equal to that. Thinner. That is, since the foam layer becomes thinner, problems may occur in thermal insulation. Therefore, when the accommodating part 410 is formed such that only a part of the refrigerating compartment evaporator 520 can be accommodated, the heat insulation problem as described above can be prevented and the storage volume can be increased.

In addition, a refrigerating chamber duct 210 which extends the upper and lower sides of the refrigerating chamber cold air generating chamber 500 to guide the cold air generated by the refrigerating chamber evaporator 520 to the upper side of the refrigerating chamber 200 is formed. The refrigerating compartment duct 210 is provided to be in close contact with the side of the refrigerating compartment side of the barrier 400, and communicates with the refrigerating compartment cold air generating chamber 500 so that the cold air can be moved smoothly. In the refrigerating chamber duct 210, a plurality of refrigerating chamber cold air discharge ports 211 for discharging cold air to the refrigerating chamber 200 are formed. The cold air discharge openings 211 may be spaced apart at predetermined intervals in the vertical direction to discharge the cold air so as to correspond to a position where the drawer 12 or the shelf 14 is provided. In addition, the cold air discharge ports 211 may be spaced apart at predetermined intervals in the front-rear direction. In this case, an effect of evenly transferring cold air to the front and rear of the drawer 12 or the shelf 14 is generated.

At this time, the side of the refrigerating chamber side of the barrier 400 is provided with a groove recessed in a predetermined depth at a position corresponding to the refrigerating chamber duct 210 can increase the size of the cross-sectional area through which cold air can flow. As a result, the cold air can be circulated more smoothly.

In addition, a refrigerating compartment cold air inlet 513 through which cold air circulated in the refrigerating compartment 200 is sucked is provided below the refrigerating compartment evaporator cover 510. In addition, when the refrigerator compartment evaporator cover 510 is formed to cover the upper surface of the refrigerator compartment evaporator 520, a refrigerator compartment cold air hole 512 is provided in the refrigerator compartment evaporator cover to allow cold air to move to the refrigerator compartment duct 210. It may be formed on the upper surface of the 510.

On the other hand, the refrigerator compartment 200 is provided with a plurality of the drawer 12 and the shelf 14 for storing food, some of which may be provided on the side of the refrigerator compartment evaporator cover 510. In this case, a rib 511 may be provided at a side of the refrigerating compartment evaporator cover 510 to guide the drawer 12 or the draw-out of the shelf 14.

In addition, a refrigerating chamber blowing fan 530 may be further formed at an upper side or an upper side of the refrigerating chamber cold air generating chamber 500 in order to smoothly discharge the cold air generated by the refrigerating chamber evaporator 520. The refrigerating compartment blowing fan 530 may be formed inside the refrigerating compartment evaporator cover 510, or may be formed at or around the same height as the refrigerating compartment cold air outlet 211. When the refrigerating compartment blowing fan 530 is provided inside the refrigerating compartment evaporator cover 510, the refrigerating compartment evaporator cover 510 shields the refrigerating compartment evaporator 520 and the refrigerating compartment blowing fan 530. It may be formed by dividing into a shielding case. In this case, by providing a shape of a portion of the refrigerator compartment evaporator cover 510 that shields the refrigerator compartment blower fan 530 in an appropriate shape according to the purpose such as a nozzle or a diffuser, cold air more smoothly. The refrigerating chamber duct 210 may be moved.

Through such a configuration, the cold air generated by the refrigerating compartment evaporator 520 is discharged into the refrigerating compartment 200 through the refrigerating compartment cold air outlet 211. Then, the food stored in the refrigerating compartment 200 is cooled and then moved back to the refrigerating compartment evaporator 520 through the refrigerating compartment cold air inlet 511.

That is, cold air is discharged from the upper side of the side surface (left side in FIG. 3) of the refrigerating chamber 200 toward the other side (right side in FIG. 3), and the discharged cold air circulates through the refrigerating chamber 200. It is sucked through the refrigerating chamber cold air suction port 511 provided below the 200. In other words, cold air is rotated clockwise in the refrigerating chamber 200.

As described above, by discharging cold air from the side of the refrigerating chamber 200, cold air is uniformly transmitted to both the front and rear of the drawer 12 or the shelf 14. Therefore, the food is cooled evenly regardless of the order in which the user stores the food in the drawer 12 or the shelf 14.

In addition, the cold air is naturally circulated in the vertical direction by the difference in density, so that the temperature distribution of the entire refrigerating chamber 200 is uniform.

Meanwhile, the refrigerating compartment evaporator 520 may be formed not only on the barrier 400 but also on the side facing the barrier 400 (the right side in FIG. 3). In this case, it is obvious that the receiving portion 410 and the refrigerating compartment duct 210 should also be formed on the side facing the barrier 400 (the right side in FIG. 3).

In addition, the freezer compartment evaporator 320 may be provided at either side of both sides of the freezer compartment 100, and the refrigerator compartment evaporator 520 may be provided at the rear side of the refrigerator compartment 200.

At this time, since the refrigerator 1 according to the embodiment of the present invention is provided with two evaporators, the evaporator located on the rear wall may be referred to as the first evaporator and the evaporator provided on the side wall as the second evaporator. For example, in an embodiment of the present invention, the freezer compartment evaporator 320 may refer to the first evaporator and the refrigerating compartment evaporator 520 as a second evaporator.

The scope of the present invention is not limited to the above-described embodiments, and the embodiments may be changed, added, or deleted within the scope of the spirit of the present invention.
