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.
Claims18
A refrigerator, comprising:
- an outer casing that defines an external appearance of the refrigerator;
- an inner casing having an open upper face, wherein the inner casing is installed within the outer casing so as to define a storage space therein, wherein the inner casing comprises:
- a casing upper portion having open top and bottom faces and four closed lateral side faces;
- and
- a separate casing lower portion having an open top face, a closed bottom face, and four closed lateral side faces, wherein an outer peripheral portion of the open top face of the casing lower portion is coupled to a corresponding outer peripheral portion of the open bottom face of the casing upper portion so as to form the storage space within the inner casing, and wherein a material of the casing lower portion has a lower thermal conductivity than a material of the casing upper portion;
- and
- a door that selectively opens and closes the open upper face of the inner casing.
A refrigerator, comprising:
- an outer casing;
- an inner casing mounted inside the outer casing, wherein a storage space is formed within the inner casing, and wherein the inner casing comprises:
- a casing upper portion formed of a first material and mounted in an upper portion of the outer casing, wherein the casing upper portion has an open bottom;
- and
- a separate casing lower portion coupled to the casing upper portion so as to form the storage space formed within the inner casing, wherein the casing lower portion is formed of a second material that is different from the first material, wherein the first material has a higher thermal conductivity than the second material, and wherein the casing lower portion is mounted in a lower portion of the outer casing;
- and
- a door that selectively open and closes the storage space formed in the inner casing.
A refrigerator, comprising:
- an outer casing that defines an external appearance of the refrigerator;
- an inner casing installed within the outer casing so as to define a storage space therein, wherein the inner casing comprises:
- a casing upper portion having open top and bottom faces and four closed lateral side faces;
- and
- a casing lower portion that is separate from and coupled to the casing upper portion, wherein the casing lower portion has an open top face, a closed bottom face, and four closed lateral side faces, and wherein an outer peripheral edge of the open top face of the casing lower portion is coupled to a corresponding outer peripheral edge of the open bottom face of the casing upper portion such that corresponding outer peripheral edges of the casing upper and lower portions are flush and form a continuous internal and external contour, wherein a material of the casing lower portion has a lower thermal conductivity and a higher specific heat than a material of the casing upper portion;
- and
- a door that selectively opens and closes the storage space defined by the inner casing.
