Problems solved by technology

[0011] According to the above technology, there is a limitation in that the interior space of the above-mentioned ducts is reduced as a whole because it is difficult to insulate these ducts, thereby increasing the loss of cold air to the outside, and the thickness of the foam part needs to be increased to insulate the ducts

Abstract

Provided is a vacuum adiabatic body. The vacuum adiabatic body includes a mullion configured to divide the first space into two spaces and a connection pipe supported on the mullion so as to be fixed in position, the connection pipe being configured to connect the two space to each other. According to the embodiment, the vacuum adiabatic body may increase in strength, and also, a passing path of defrosting water may be secured.

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...
