Abstract

L'invention concerne un réfrigérateur, qui peut sceller un espace existant entre une paire de portes en tournant une barre de rotation même lors de l'ouverture et de la fermeture d'une porte, d'entre la paire de portes, qui n'a pas de barre de rotation y installée. Le réfrigérateur comprend : une barre de rotation pour sceller un espace entre une première porte et une seconde porte ; et un dispositif de guidage pour induire la rotation de la barre de rotation. Le dispositif de guidage comprend : un support qui est déplacé de façon linéaire dans une direction vers l'avant et vers l'arrière en fonction de l'ouverture et de la fermeture de la seconde porte, et a un second aimant intégré en son sein ; un pignon qui est accouplé au support et tourné lorsque le support est déplacé de façon linéaire ; et une unité de guidage qui a une rainure de guidage pour guider une saillie de guidage et est accouplée au pignon de façon à tourner la barre de rotation, tout en se déplaçant de façon linéaire dans une direction opposée au support lorsque le pignon est tourné.
