VACUUM ADIABATIC BODY AND REFRIGERATOR

Title:

VACUUM ADIABATIC BODY AND REFRIGERATOR

Document Type and Number:

WIPO Patent Application WO/2017/023075

Kind Code:

A1

Abstract:

A vacuum adiabatic body includes: a first plate member defining at least one portion of a wall for a first space; a second plate member defining at least one portion of a wall for a second space having a different temperature from the first space; a sealing part sealing the first plate member and the second plate member to provide a third space that has a temperature between the temperature of the first space and the temperature of the second space and is in a vacuum state; a supporting unit maintaining the third space; a heat resistance unit for decreasing a heat transfer amount between the first plate member and the second plate member; and an exhaust port through which a gas in the third space is exhausted, wherein the vacuum adiabatic body further includes a peripheral adiabatic part provided to an outer wall of an edge portion of the third space to improve the adiabatic performance of the edge portion of the third space, and the peripheral adiabatic part is provided as a separate adiabatic member. Accordingly, it is possible to improve an adiabatic effect and to increase the volume of an outer door in a door-in-door refrigerator.
