  • Patent number: 6840057
    Abstract: An improved structure for uniformly distributing cold air throughout a refrigerator is provided. Cold air is discharged vertically downward through a cooling air supply device positioned in an upper portion of the refrigerator to reduce temperature variation between an upper part of the refrigerator and a lower part of the refrigerator so that temperature in the refrigerator may be maintained at a uniform level. Positioning the cooling air supply device and distributing the colling air in this manner obviates the need for additional equipment positioned throughout the refrigerator to augment cooling capability, thus allowing for optimized use of space in the refrigerator.

  • Publication number: 20040144125
    Abstract: Disclosed is a structure for discharging cold air in a refrigerator capable of uniformly distributing the cold air regardless of the upper part and the lower part of the refrigerator, by discharging the cold air in vertically downward direction. Therefore, temperature difference between the upper part and the lower part is reduced, so that temperature in the inside of the refrigerator could be uniformly maintained. Thanks to such structure having the foregoing advantages, additional equipment and space for supplying cold air to the shelf are not necessary any more like the case of the freezer or the cooling chamber according to the related art, having the structure where the discharging hole is formed on each shelf, so that the space of the refrigerator could be effectively used.
