Hereinafter, for ease of explanation, the freezing chamber 7 and the refrigerating chamber 9 will be collectively described as a cooling chamber.

A compressor 23 for compressing a refrigerant is provided at the lower rear end of the refrigerator main body 3, and between the rear wall of the cooling chamber and the rear wall of the refrigerator main body 3, a refrigeration for cooling ambient air by latent heat of evaporation of the refrigerant. The evaporator 25 and the refrigeration evaporator 27 are provided, respectively. A blowing fan 29 for blowing cold air is provided near each of the evaporators 25 and 27. A cold air duct 31 is installed to guide the cold air flowing through the blower fan 29, and a duct cover 33 having a cold air discharge port (not shown) is provided on the front side of the cold air duct 31. The discharge guide 35 is provided in the cold air discharge port.

3 is an exploded perspective view of the duct cover mounted in FIG. 1. As shown in this figure, the duct cover 33 is formed in an arc shape so as to protrude toward the cooling chamber, and is provided with a cold air discharge port 35 opened for discharging cold air into the cooling chamber. In the cold air discharge port 35, a plurality of plate-shaped discharge guides 37 for guiding and dispersing the discharge angle of the cold air discharged into the cooling chamber are injection molded integrally with the duct cover 33. In the drawings, some of the discharge guides 37 integrally formed with the duct cover 33 are separately illustrated for ease of explanation. The discharge guides 37 are arranged radially perpendicular to the cold air discharge port 35.

By this configuration, the cold air flowing along the cold air duct 31 passes through the cold air discharge port 35 opened toward the cooling chamber provided in the duct cover 33 provided on the front surface of the cold air duct 31. Discharged. The cold air discharged to the cooling chamber is dispersed in the cooling chamber while the discharge angle is radially spread by the plurality of discharge guides 37 arranged in the radially perpendicular direction with respect to the cold air discharge port 35.

Accordingly, the cold air diffusion area of the cold air discharged to the cooling chamber is widened, and thus the temperature distribution in the cooling chamber can be maintained evenly as the cold air is uniformly discharged to the cooling chamber as a whole.

4 is an exploded perspective view of the duct cover according to another embodiment of the present invention. As shown in this figure, the duct cover 33 is provided with a plurality of cold air discharge ports 35 opened on an arcuate surface formed to protrude toward the cooling chamber.

Accordingly, the cold air discharge area is widened to uniform the temperature distribution in the cooling chamber, and the cold air discharge port 35 partitioned in the duct cover makes the beauty in the cooling chamber beautiful.

5 is an exploded perspective view of the duct cover according to another embodiment of the present invention. As shown in FIG. 4, as described with reference to FIG. 4, the discharge guide 37 and the upper and lower discharge guides 39 are provided at the cold air discharge ports 35 opened toward the cooling chamber provided in the duct cover 33. It is installed. Further, a cold air distribution device 41 is provided behind the duct cover 33 adjacent to the cold air discharge port 35.

The cold air distribution device 41 is composed of a rotation shaft 43, a plurality of cold air distribution blades 45, and a drive motor 47 for rotating the rotation shaft 43. As shown in FIG. The rotary shaft 43 is coupled to the drive motor 47 to rotate. Cold air distribution wing 45 is formed of a plate-shaped body curved in a wave shape with respect to the plane including the axis of the rotary shaft 43, are spaced apart from each other to correspond to each cold air discharge port 35 along the rotary shaft 43 have. At the upper and lower ends of each cold air distributing wing 45, a pair of end plates 49 formed of an upper plate 49a and a lower plate 49b on the disc is formed, and an intermediate plate between the upper plate 49a and the lower plate 49b. 51 is provided and partitions the cold air | distribution blade 45 into the 1st blade | wing part 53 and the 2nd blade | wing part 55. As shown in FIG. Each wing part 53 and 55 is bent so that a cross section may form an S shape, and the wing parts 53 and 55 of each cold air | distribution wing 45 are bent in the opposite direction.

By this configuration, when the cold air flowing along the cold air duct 31 meets the cold air distribution device 41, the cold air is bent plate of the cold air distribution blade 45 that rotates at a low speed by the drive motor 47 By the flow direction is converted to the left and right is directed to the cold air outlet 35 provided in the duct cover (33). As described with reference to FIG. 4, the cold air directed to the cold air discharge port 35 is dispersed by the discharge guide 37 and the vertical discharge guide 39 and discharged into the cooling chamber.

Accordingly, the cold air discharged into the cooling chamber through the cold air discharge port 35 is converted to the left and right flow direction by the rotating cold air distribution blade 45 of the cold air distribution device 41, discharge guide 37 and up and down discharge Since the discharge angle is distributed not only radially but also vertically by the guide 39 and is discharged into the cooling chamber, the cold air diffusion area is widened.

As described above, according to the present invention, the cold air discharged into the cooling chamber through the cold air discharge port has an effect of widening the cold air discharge area because the discharge angle is guided by a plurality of discharge guides provided on the opening surface of the cold air discharge port. There is provided a refrigerator in which the temperature distribution in the cooling chamber is kept even.
