Abstract

DC60 (18/10/54) to provide timely reliability with thermal insulation performance. improved The refrigerator includes rigid urethane foam with sealed cavity 4, vacuum insulating material 3 and condensation tube 6 arranged between its outer frame 1 and its inner frame 2, at The vacuum insulating materials include gas-barrier encapsulations, encapsulated materials. that is formed by layers of film one with metallic foil and a second layered film with a dialuminum deposition layer or an overlapping alumina deposition layer. and weld with The heat at its circumference is created into a sac-like envelope which is vacuumed. and sealed with a core material inside it and condensation tubes are arranged on top of the outer frame And the vacuum insulating material is embedded in a rigid polyurethane foam with a cavity that closes between the frame, outer frame and inner frame in such a way that the films are stacked. the second with the alumina vapor deposition layer or the alumina vapor deposition layer facing the condensation tube.

Disclaimer (all) which will not appear on the advertisement page: Amendment 13/09/2019 No disclaimer ---------- Page 1 of the number 1 disclaimer page 1. a refrigerator, which includes Outer frame Inner frame Rigid urethane foam with a closed cavity placed between the outer frame. And the inner frame A vacuum insulated material placed between the outer frame and the inner frame, and the condensing tube positioned between the outer frame. And the inner frame At the vacuum insulating material socket, including the encapsulated material having gas barrier properties, the encapsulated material that is formed by a layered film. Where there is a metallic foil and a layered film A second with an aluminum vapor deposition layer, or alumina vapor deposition layer, that is overlapped and heated at its circumference, formed into a bag-like encapsulation, vacuumed and Sealed with core material inside it Where the condensation tube is located on the outer frame side. Vacuum insulated material is placed through a spacer arranged on the outer frame, and the spacer is formed in a zigzag shape and where the vacuum insulated material is embedded. In rigid urethane foam with a cavity that \ 'closes to Avoid insertion with condensation tubes using the spacer serrated shape. In such a way that the films overlapping layers The second with an aluminum vapor deposition layer or a vapor deposition layer Alumina facing the condensation pipe 2. Refrigerators of claim I where vacuum insulated material is 85 percent covered, or Greater than the total length of the condensing tube positioned between the outer frame and the inner frame. 3. The refrigerator of claim 1 or 2 on the side, when viewed from the inner frame side, the vacuum heat insulating material was placed only on the side, the condensation tube was inserted. In order to cover the condensation pipe and not, it was placed on the other side. The condensation tube was not placed.
