Abstract

La présente invention concerne un réfrigérateur comportant un compresseur (120) sur une section de surface supérieure d’un corps de boîtier isolant thermique (101). Une salle de réfrigération est formée d’un seul tenant en plaçant un matériau en mousse isolant thermique (132) dans un segment isolant thermique qui forme une salle de réfrigération (110) en tant que salle de stockage la plus haute. Ceci augmente la rigidité de la salle de stockage la plus haute, et en conséquence, les vibrations générées par le compresseur placé sur la section de surface supérieure de la salle de stockage la plus haute peuvent être empêchées de se propager vers un corps de réfrigérateur. Egalement, le phénomène de propagation des vibrations provenant du compresseur vers d’autres parties et le bruit entraîné par les vibrations des parties peuvent être supprimés.
