Abstract

La présente invention concerne un réfrigérateur comprenant : une armoire comprenant une chambre de stockage qui a une ouverture formée sur le côté avant de celle-ci ; une porte reliée pivotante à l'armoire de façon à ouvrir et à fermer l'ouverture ; un tiroir disposé à l'intérieur de la chambre de stockage de manière à recevoir des produits stockés ; un guide de tiroir pour supporter le tiroir, et guidant le tiroir de telle sorte que le tiroir peut être avancé et reculé ; une partie de base disposée sous le tiroir ; un mécanisme de retrait comprenant un châssis arrière qui s'étend vers l'arrière du tiroir depuis la partie de base de manière à pousser le tiroir vers l'avant lorsque la partie de base est avancée ; un élément de liaison ayant une extrémité avant reliée à la porte au niveau d'un point, qui est positionné à une distance prédéfinie de l'axe de rotation de la porte par rapport à l'armoire, de manière à former un premier joint rotatif, et ayant une extrémité arrière reliée à la partie de base de manière à former un second joint rotatif ; et une paire de guides de mécanisme de retrait disposés espacés l'un de l'autre dans le sens de la largeur de la chambre de stockage de manière à guider la partie de base de telle sorte que la partie de base est avancée et reculée, le premier joint rotatif et le second joint rotatif étant disposés à l'opposé l'un de l'autre par rapport à une ligne de référence positionnée de façon équidistante de la paire de guides de mécanisme de retrait.
