Abstract
The refrigerator includes a body having a storage space for storing a predetermined storage object, wherein the body includes an inner case having the storage space, an outer case having an inside surface spaced a predetermined gap from an inside surface of the inner case to house the inner case, a vacuum space provided between the inner case and the outer case enclosed to maintain a vacuum state for heat insulating between the inner case and the outer case, and a sealing unit for sealing a front of the vacuum space formed between a front of the inner case and a front of the outer case and reducing a heat transfer rate between the inner case and the outer case.
Claims11
A refrigerator comprising:
- a body having a storage space,
- wherein the body includes;
- an inner case having the storage space,
- an outer case having an inside surface spaced a predetermined gap from an outside surface of the inner case to house the inner case,
- a vacuum space provided between the inner case and the outer case and sealed to maintain a vacuum state for heat insulating between the inner case and the outer case, and
- a sealing unit for sealing a front of the vacuum space formed between a front of the inner case and a front of the outer case and reducing a heat transfer rate between the inner case and the outer case, wherein the sealing unit includes:
- a blocking member arranged in front of the vacuum space connected between a front edge of the inner case and a front edge of the outer case to block the front of the vacuum space, the blocking member defining a curved locus of a heat transfer path between the inner case and the outer case,
- a filling member of an insulating material provided in front of the blocking member, the filling member being in contact with a portion of the blocking member that defines the curved locus of the heat transfer path between the inner case and the outer case and having a curved surface in conformity with the curved locus of the heat transfer path between the inner case and the outer case,
- a reinforcing member arranged in a space defined by the blocking member in front of the filling member for securing a position of the filling member and reinforcing strength of the sealing unit, the reinforcing member being located inside of the inner case and the outer case, extending between the inner case and the outer case, and being aligned with the front edges of the inner case and the outer case, and
- a front cover that connects and seals the front edges of the inner case and the outer case, the front cover completely covering the reinforcing member and
- the filling member and extending across the front edges of the inner case and the outer case,
- wherein the blocking member includes a first coupling portion coupled to and supported on the front edge of the inner case and a second coupling portion coupled to and supported on the front edge of the outer case.

A refrigerator comprising:
- a body having a storage space;
- a wall that is part of the body and includes an inner case and an outer case;
- a vacuum space formed in the wall sealed to maintain a vacuum state for heat insulating between an outside of the body and the storage space;
- and
- a sealing unit arranged in front of the wall to seal a front of the vacuum space,
- wherein the sealing unit includes:
- a blocking member arranged in front of the vacuum space connected between a front edge of the inner case and a front edge of the outer case to block the front of the vacuum space, the blocking member defining a curved locus of a heat transfer path between the inner case and the outer case,
- a filling member of an insulating material provided in front of the blocking member, the filling member being in contact with a portion of the blocking member that defines the curved locus of the heat transfer path between the inner case and the outer case and having a curved surface in conformity with the curved locus of the heat transfer path between the inner case and the outer case,
- a reinforcing member arranged in a space defined by the blocking member in front of the filling member for securing a position of the filling member and reinforcing strength of the sealing unit, the reinforcing member being located inside of the inner case and the outer case, extending between the inner case and the outer case, and being aligned with the front edges of the inner case and the outer case, and
- a front cover that connects and seals the front edges of the inner case and the outer case, the front cover completely covering the reinforcing member and the filling member and extending across the front edges of the inner case and the outer case,
- wherein the blocking member is thinner than the inner case and the outer case, and
- wherein the blocking member includes a first coupling portion coupled to and supported on the front edge of the inner case and a second coupling portion coupled to and supported on the front edge of the outer case.

A refrigerator comprising:
- a body having a storage space,
- wherein the body includes:
- an inner case having the storage space,
- an outer case having an inside surface spaced a predetermined gap from an outside surface of the inner case to house the inner case,
- a vacuum space provided between the inner case and the outer case and sealed to maintain a vacuum state for heat insulating between the inner case and the outer case, and
- a sealing unit for sealing a front of the vacuum space formed between a front of the inner case and a front of the outer case and reducing a heat transfer rate between the inner case and the outer case,
