Abstract

La présente invention concerne un réfrigérateur doté d'un ensemble commutateur, comprenant un corps principal, une porte destinée à ouvrir et fermer le corps principal et un ensemble charnière destiné à relier le corps principal à la porte. Le corps principal comprend une chambre de récipient et un côté pivot destiné à relier l'ensemble charnière. L'ensemble charnière comprend une première charnière, une deuxième charnière et un ensemble commutateur destiné à relier la première charnière à la deuxième charnière. Lorsque la porte se trouve dans le processus d'ouverture, la première charnière se déplace tout d'abord par rapport à l'ensemble commutateur, puis la deuxième charnière se déplace par rapport à l'ensemble commutateur, l'ensemble charnière entraînant tout d'abord la porte à se déplacer depuis le côté pivot vers la chambre de récipient, puis l'ensemble charnière entraînant la porte à se déplacer de la chambre de récipient vers le côté pivot. Le réfrigérateur selon la présente invention peut augmenter le degré de liberté d'ouverture et de fermeture de la porte et peut avoir divers trajets de déplacement de façon à s'adapter à différents scénarios d'application.
