Abstract

Un réfrigérateur utilise un corps de cloison (122) pour diviser l'intérieur d'un boîtier principal (101) en des compartiments de stockage auxquels de l'air de refroidissement est fourni, et une porte pouvant être ouverte et fermée (119) est disposée au niveau des côtés avant des compartiments de stockage. La porte (119) est dotée d'un joint d'étanchéité (121) qui est en contact étroit avec un élément de contact métallique (123) formé au niveau de la surface avant du corps de cloison (122) qui est situé du côté de la porte. Le réfrigérateur présente une configuration de chauffage des éléments de contact (123), ainsi qu'une section de suppression (124) qui supprime l'échange de chaleur entre l'air de refroidissement dans les compartiments de stockage et l'élément de contact (123).
