Abstract

L'invention porte sur un réfrigérateur, qui comporte une enceinte d'isolation thermique, une paire de parties d'attachement d'élément de renfort et un élément de renfort en forme de pont. L'enceinte d'isolation thermique est configurée sous une forme de boîte, et a un matériau d'isolation thermique pris en sandwich entre une plaque externe pour constituer la surface externe du réfrigérateur, et une plaque interne pour constituer la surface interne du réfrigérateur. La paire de parties d'attachement d'élément de renfort sont respectivement positionnées sur la paire de plaques internes qui se font mutuellement face à l'intérieur du réfrigérateur. Une extrémité de l'élément de renfort en forme de pont est reliée à l'une des parties d'attachement d'élément de renfort dans la paire, tandis que l'autre extrémité de celui-ci est reliée à l'autre partie d'attachement d'élément de renfort.
