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.
Claims20
An appliance having a case, the case comprising:
- an inner case that defines a storage space;
- an outer case spaced apart from the inner case, the outer case and the inner case defining, between the outer case and the inner case, a vacuum space that is maintained at a vacuum pressure and that is configured to insulate the inner case from the outer case;
- spacers that are spaced apart from each other and that maintain the vacuum space between the inner case and the outer case;
- a radiation blocking film provided in the vacuum space and spaced apart from the inner case and the outer case, the radiation blocking film comprising one or more through-holes;
- and
- one or more distance keeping members provided to one or more of the spacers, each of the one or more distance keeping members having an outer circumference larger than a circumference of a corresponding through-hole of the one or more through-holes and supporting the radiation blocking film by an end surface of the distance keeping member.

- spacers that are spaced apart from each other and that maintain the vacuum space between the inner case and the outer case;
- a radiation blocking film provided in the vacuum space and spaced apart from the inner case and the outer case, the radiation blocking film comprising one or more through-holes;
- and
- a first distance keeping member provided to one or more of the spacers, the first distance keeping member having an outer circumference larger than a circumference of a corresponding through-hole of the one or more through-holes;
- a second distance keeping member provided to one or more of the spacers, the second distance keeping member having an outer circumference larger than a circumference of a corresponding through-hole of the one or more through-holes,
- wherein the radiation blocking film is supported between the first distance keeping member and the second distance keeping member.
