In detail, the first guide rib 412 includes a plurality of ribs spaced in the longitudinal direction in the first outlet hole 413. The first guide rib 412 is disposed to be inclined downward or rounded toward the front of the partition cover 400.

Therefore, the cold air may flow toward the side and the bottom of the freezing chamber 30 in the process of being discharged from the first outlet hole 413. As such, since cold air is discharged downwardly from the upper outlet 411, cold air circulation may be smoothly performed in the freezing chamber 30.

At least a part of the first guide rib 412 may be disposed to be inclined forward, and another part of the first guide rib 412 may be disposed to be inclined backward. That is, it may be disposed together with the second guide rib 416 and the third guide rib 417 to be described later.

In this case, the cold air discharged from the first outlet hole 413 may be discharged to the front and the rear of the freezing chamber 30 (see FIG. 10).

In addition, the inlet guide 432 is disposed to be rounded upwardly of the partition cover 400. Therefore, the cold air may flow upward in the process of flowing into the compartment 400 through the inlet hole 434.

Since the evaporator 110 is disposed above the inlet hole 434, the cool air introduced into the compartment 400 may easily flow toward the evaporator 110. That is, when the suction force is applied to the inlet hole 434 while the fan motor assembly 130 is driven, the cold air of the freezing compartment 30 is guided smoothly toward the evaporator 110, and in this process Flow losses can be reduced.

As described above, the cold air discharged from the cover outlets 411, 415, and 419 may move downward while uniformly cooling the freezer compartment 30, and may be guided toward the evaporator 110 at the cover inlet 430.

In addition, the cold air is heat-exchanged in the evaporator 110, and moves upwards according to the driving of the blower fan 134.

Since the flow of cold air to the cold air flow unit 230 through the fan motor assembly 130 is the same as that described with reference to FIG. 10, a description thereof will be omitted.

Meanwhile, the cold air guided through the cold air flow part 230 is supplied to the damper member 142 on the upper end of the cold air flow part 230. In the state where cold air is supplied to the refrigerating chamber 40, the damper member 142 is opened. At least a portion of the cold air flowing in the cold air flow unit 230 is discharged to the cold air outlet 232 through the cold air distribution device 140.

The cold air supplied into the refrigerating compartment 40 through the cold air outlet 232 cools the inside of the refrigerating compartment 30. In addition, the cold air circulating in the refrigerating compartment 40 may be introduced into the compartment 100 through the cold air inlet 212 to be heat exchanged.

In the plurality of guide ribs, a plurality of side surfaces spaced apart from the central guide 235 and the central guide 235 to the side of the outlet grill 234 are arranged in the longitudinal direction at an approximately central portion of the refrigerating chamber exit hole 237. A guide is included. The lateral guide is inclined with respect to the vertical line.

The plurality of side guides may include a first side guide 236 adjacent to the center guide 235 and a second side guide spaced apart from the first side guide 236 in the side end direction of the outlet grill 234. 237).

The angle β in which the first side guide 236 is inclined with respect to the vertical line is smaller than the angle α in which the second side guide 237 is inclined with respect to the vertical line. That is, the plurality of side guides are arranged to be inclined gradually toward the side ends from the center guide 235.

In this case, the cold air guided by the side guide may be evenly discharged to the front and rear of the refrigerating chamber 40.

Of the cold air discharged from the outlet grill 234, the cold air guided by the center guide 235 is discharged toward the side of the refrigerating compartment 40, the cold air guided by the side guides (236, 237) It is discharged toward the front or the rear of the 40.

Although not shown in the drawings, the configuration of the inlet grill 214 may be configured to correspond to the outlet grille. That is, the inlet grill 214 may include a center guide and a side guide for allowing cold air to flow from front, rear, and side of the refrigerating chamber 40.

Alternatively, the inlet grill 214 may have the same configuration as the cover inlet 430.

According to the above configuration, since the cold air discharged into the refrigerating compartment 40 can be spread evenly in the storage space of the refrigerating compartment 40, there is an advantage that the cooling effect can be increased.

In this embodiment, the configurations of the cover outlets 411, 415, 419 and the outlet grille 234 have been distinguished and described. However, alternatively, the configuration of the cover outlets 411, 415, 419 may be applied to the outlet grill 234, or the configuration of the outlet grill 234 may be applied to any one of the cover outlets 411, 415, 419. Will be readily understood.

In addition, for convenience of description, the cover outlets 411, 415, 419 and the outlet grille 234 may be collectively referred to as "cold air discharge parts", and the cover inlet 430 and the cold air inlet 212 may be collectively referred to as " Cold air inlet. "
