  • Patent number: 7677681
    Abstract: A refrigerator having improved cooling and cooling recovery is provided. A main body of the refrigerator may include an outer casing that defines an external appearance of the refrigerator, and an inner casing with an open upper face installed in the outer casing to define a storage space therein. The open upper face of the main body may be opened and closed by a door. The inner casing may include a casing upper portion and a casing lower portion coupled to the bottom of the casing upper portion. The casing lower portion may be formed of a material different from that of the casing upper portion. The casing upper portion may be made of a material having a high thermal conductivity, and the casing lower portion may be made of a material having a lower thermal conductivity that that of the casing upper portion.

  • Patent number: 7670018
    Abstract: An illumination device for a refrigerator and a method of controlling the same are provided. The illumination device includes a lamp assembly that irradiates light to an inside of a storage chamber of the refrigerator, a base plate mounted on a side within the storage chamber, wherein the lamp assembly is provided on a side of the base plate, a watertight cover formed to enclose the lamp assembly blocking direct penetration of water into the lamp assembly, and at least one fastening device formed on a side of the base plate. The at least one fastening device surrounds an outer surface and an inner surface of entire lower edge of the watertight cover along a side of the watertight cover forming a recess-prominence engagement with the watertight cover. Lamps provided in the lamp assembly are individually controlled through a manipulation panel mounted on the main body.

  • Publication number: 20090097227
    Abstract: Disclosed are an illumination device for a refrigerator and a method of controlling the same. The illumination device includes: a lamp assembly for irradiating light to the inside of a storage chamber of a refrigerator; a base plate mounted on a side within the storage chamber, the lamp assembly being provided on a side of the base plate; a watertight cover formed to enclose the lamp assembly so as to block the direct penetration of water into the lamp assembly; and a fastening means formed on a side of the base plate to surround the watertight cover so as to form a recess-prominence engagement with the watertight cover. Lamps provided in the lamp assembly are individually controlled through a manipulation panel mounted on the main body. If the refrigerator door is opened, the driving of the lamp assembly is stopped. In addition, the lamp assembly irradiates different colored lights depending on the kind of food.

  • Publication number: 20060250061
    Abstract: A main body of a kimchi refrigerator according to the present invention comprises an outer casing for defining an external appearance of the refrigerator and an inner casing with an open upper face installed in the outer casing to define a storage space therein. Further, a door of the refrigerator opens and closes the open upper face of the main body. The inner casing of the kimchi refrigerator according to the present invention includes a casing upper portion in the form of a box and a casing lower portion coupled to the bottom of the casing upper portion and formed of a material different from that of the casing upper portion. The casing upper portion is made of a material with high thermal conductivity, e.g. aluminum or the like, and the casing lower portion is made of a material with lower thermal conductivity than that of the casing upper portion.
