Le corps de réfrigérateur comprend un revêtement interne, un logement situé à l'extérieur du revêtement interne, et une cavité d'isolation thermique formée entre le revêtement interne et le logement. Le réfrigérateur comprend en outre une boîte de montage disposée entre le revêtement interne et le logement, une carte de commande principale disposée dans la boîte de montage, et un ensemble de commande d'affichage connecté électriquement à la carte de commande principale. La boîte de montage est pourvue d'une ouverture qui la traverse jusqu'à l'extérieur servant à monter ou démonter la carte de commande principale. L'ensemble de commande d'affichage est disposé au niveau de l'ouverture et exposé vers l'extérieur à partir du logement. Selon la présente invention, la longueur d'un faisceau de câbles reliant l'ensemble de commande d'affichage et la carte de commande principale peut être réduite, de telle sorte que l'agencement et la disposition du faisceau de câbles sont facilités, et le retard de signal est relativement faible ; de plus, l'ensemble de commande d'affichage est configuré sous la forme d'une plaque de recouvrement de la boîte de montage, de sorte que la structure est simplifiée et le coût est réduit.
