Title (EN) VACUUM INSULATED DOOR CONSTRUCTION
(FR) STRUCTURE DE PORTE ISOLÉE SOUS VIDE
Abstract:
(EN) A method of fabricating a refrigerator cabinet or door includes forming a wrapper and an inner liner. The method further includes forming a vacuum insulated core comprising a permeable core material that is disposed inside an impermeable envelope. A sheet of prefabricated compressible foam material is positioned between the vacuum insulated core between the inner door liner and/or the door wrapper. The prefabricated compressible foam material may be cut from a sheet of foam having substantially uniform thickness prior to fabrication of the refrigerator door. The foam compresses to accommodate differences in spacing between the vacuum insulated core and the door wrapper and/or the door liner.
(FR) L'invention concerne un procédé de fabrication d'une armoire ou d'une porte de réfrigérateur, le procédé comportant la formation d'une caisse et d'un revêtement interne. Le procédé comporte en outre la formation d'un noyau isolé sous vide comprenant un matériau de noyau perméable disposé à l'intérieur d'une enveloppe imperméable. Une feuille de mousse compressible préfabriquée est placée entre le noyau isolé sous vide et le revêtement de porte interne et/ou la caisse de porte. La mousse compressible préfabriquée peut être découpée à partir d'une feuille de mousse présentant une épaisseur sensiblement uniforme avant la fabrication de la porte de réfrigérateur. La mousse se comprime afin de s'adapter aux différences d'espacement entre le noyau isolé sous vide et la caisse de porte et/ou le revêtement de porte.
