Abstract

La présente invention divulgue un mécanisme de charnière et un dispositif de réfrigération intégré. Le mécanisme de charnière comprend un premier élément de charnière installé sur une boîte, et un second élément de charnière installé sur une porte. Lorsque le second élément de charnière effectue une ouverture rotative, le second élément de charnière se déplace d'abord vers un côté pivotant et dans une direction s'éloignant du premier élément de charnière, puis se déplace vers un côté d'ouverture, de telle sorte que l'interférence entre la porte et une paroi d'armoire peut être évitée.
