Problems solved by technology

However, its limitation is that the manufacturing is complicated and the internal volume of the refrigerator is greatly reduced
[0008] Also, since the inner space of the vacuum insulator is empty in a vacuum state, there is a limitation that, when compared with an object filled with a resin material such as urethane according to the prior art, the vacuum insulator produces Deformations such as bending, buckling

Abstract

A vacuum adiabatic body is provided. The vacuum adiabatic body includes a cover assembly configured to cover an anti-conductive sheet. The cover assembly includes: an inner cover configured to protect an inner side; an outer cover configured to protect an outer side; and a front cover configured as a front side, and at least one of the inner cover or the outer cover extends toward the other end of the at least one of the first plate or the second plate. According to these embodiments, the edge and side surfaces of the vacuum adiabatic body may be protected together.

Description

technical field [0001] The present disclosure relates to vacuum insulation and refrigerators. Background technique [0002] A vacuum insulator is a product that suppresses heat transfer by applying a vacuum to the inside of its main body. Vacuum insulation reduces heat transfer by convection and conduction and is therefore used in heating and cooling equipment. In a typical insulation method applied to a refrigerator, although its application is different in refrigeration and freezing, a foamed polyurethane insulation wall having a thickness of about 30 cm or more is generally provided. However, the internal volume of the refrigerator is thus reduced. [0003] In order to increase the internal volume of refrigerators, attempts have been made to apply vacuum insulators to refrigerators. [0004] First, Korean Patent No. 10-0343719 (reference 1) of the present applicant has been published. According to Reference 1, there is disclosed a method of preparing a vacuum insulati...
