Abstract
There is disclosed a refrigerator including a vacuum space formed between an outer case and an inner case to improve an insulation function thereof, which includes an inner case that defines an exterior appearance of a storage space, an outer case spaced apart a predetermined distance from the inner case, a vacuum space provided between the inner case and the outer case, with being maintained vacuum, to insulate the inner case from the outer case, a plurality of spacers for supporting the inner case and the outer case space that are spaced apart from each other, and a radiation blocking film provided in the vacuum space, spaced apart from the inner case and the outer case.
Claims21
An appliance comprising:
- a first case;
- a second case spaced apart from the first case;
- a vacuum space having a thickness in a first direction between the first case and the second case;
- a support configured to reduce deformation of the first case, and including a portion that extends in the first direction;
- a radiation sheet configured to reduce radiation heat transfer and including a portion that extends in a second direction different from the first direction;
- and
- a distance keeping member configured to reduce movement of the radiation sheet and having a thickness in the first direction,
- wherein the radiation sheet is disposed not to contact the support, and
- wherein the distance keeping member has an outer surface inclined along the first direction to make a diameter of the distance keeping member smaller along the first direction.

An appliance comprising:
- a first case;
- a second case spaced apart from the first case;
- a vacuum space having a thickness in a first direction between the first case and the second case;
- a support configured to reduce deformation of the first case, and including a portion that extends in the first direction;
- and
- a radiation sheet configured to reduce radiation heat transfer,
- wherein the support includes:
- a first support plate;
- a second support plate spaced apart from the first support plate;
- and
- a plurality of spacers that are spaced apart from each other and that maintain the vacuum space between the first case and the second case,
- wherein the radiation sheet is disposed between the first support plate and the second support plate,
- wherein the radiation sheet comprises a through-hole that enables the spacers to pass through the radiation sheet, the through-hole being formed at a position corresponding to a position of each of the spacers, and
- wherein a diameter of the through-hole is larger than a diameter of the each of the spacers.
