Abstract
Provided is a vacuum adiabatic body. To reduce a heat transfer amount between two plates, the vacuum adiabatic body includes: a conductive resistance sheet connecting plate members to each other, an exhaust port through which a gas of a third space is exhausted, and a sealing frame covering a conductive resistance sheet. A virtual line connecting both end portions of the conductive resistance sheet to each other is installed to be obliquely inclined when at least one extension direction of a first plate member or a second plate member is viewed in a horizontal direction.
Claims20
A refrigerator comprising:
- a main body having a vacuum adiabatic body to form a first space configured to store items,
- wherein the vacuum adiabatic body includes:
- a first plate configured to define at least a portion of a wall for the first space;
- a second plate configured to define at least a portion of a wall for a second space external to the refrigerator;
- a third space that is provided between the first plate and the second plate and is configured as a vacuum space;
- and
- a heat resistance sheet coupled to at least one of the first plate or the second plate to seal the third space;
- a door provided to open and close an opening of the main body to allow access to the first space;
- a gasket installed on one of the door or the main body;
- and
- a sealing frame provided between the third space and a portion of the door, the sealing frame including a side wall that contacts the gasket when the door closes the opening and that separates from the gasket when the door opens the opening,
- wherein the side wall of the sealing frame is inclined with respect to an extension direction of at least one of the first plate or the second plate in a horizontal or vertical direction.
