Vacuum adiabatic body and refrigerator

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.

Description

technical field [0001] The present disclosure relates to a vacuum insulator and a refrigerator. Background technique [0002] A vacuum insulator is a product that suppresses heat transfer by vacuuming the inside of the body. Vacuum insulation can reduce heat transfer by convection and conduction, and is therefore applied to heating and refrigeration installations. In a typical heat insulating method applied to a refrigerator, foam urethane is generally provided with a heat insulating wall having a thickness of about 30 cm or more, although its application in refrigeration and freezing is different. However, the internal volume of the refrigerator is thus reduced. [0003] In order to increase the internal volume of the refrigerator, try to apply vacuum insulation to the refrigerator. [0004] First, Korean Patent No. 10-0343719 (Cited Document 1) of the present applicant has been published. According to reference document 1, a method is disclosed in which a vacuum insula...

AI Technical Summary

Problems solved by technology

[0009] According to Citation 5, the internal volume of the refrigerator is increased, but the contact area between the liner and the sealing frame is still narrow, and therefore, sufficient thermal insulation performance may not be achieved

Also, there is a limitation in that since it is sealed not only by the contact of the gasket but also an air layer, it is difficult to form an energy nose as a thermal insulation gap portion, resulting in deterioration of thermal insulation efficiency
