Abstract

La présente invention concerne un réfrigérateur comportant : une chambre à moteur reliée à un corps de réfrigérateur ; et un condenseur disposé dans la chambre à moteur, le condenseur étant conçu pour disposer un tuyau passant à travers un groupe d'ailettes. Le condenseur est installé dans la chambre à moteur dans un état suspendu. Les vibrations, qui pourraient autrement se propager à travers le condenseur, sont ainsi absorbées par le condenseur sans se propager. En outre, même dans le cas d'une faible vibration se propageant à travers le condenseur, la transmission de ladite vibration au corps du réfrigérateur est réduite au minimum. Par conséquent, il est possible de réduire efficacement au minimum les vibrations du corps de réfrigérateur.
