Abstract

refrigerator, comprising a cabinet, a door 20 for opening and closing the cabinet 10, and a hinge assembly 30 for connecting the cabinet 10 and the door 20. The hinge assembly 30 comprises a first shaft 311, a first groove 321, a second shaft 312 and a second groove 322, the first shaft 311 and the first groove 321 are fitted with each other, the second shaft 312 and the second groove 322 are fitted with each other. The first shaft 311 is located in one of the cabinet and the door, the first groove 321 is located in the other of the cabinet 10 and the door, the second shaft 312 is located in one of the cabinet and the door, and the second groove 322 is located in the other of the cabinet and the door. The cabinet 10 comprises an accommodating chamber and an outer side surface 13 adjacent to the hinge assembly 30 and located on an extension section of a rotation path of the door. A direction X from the accommodating chamber towards the outer side surface 13 serves as a first direction, and a direction Y from the door 20 towards the cabinet serves as a second direction. When the door 20 is in an opening process, the hinge assembly 30 drives the door 20 to move away from the cabinet 10 in the first direction, and meanwhile, the hinge assembly drives the door to move towards the cabinet in the second direction. The inventive feature is the angle of the groove 321 which is angled towards the outer side section and away from the interior of the cabinet. This bi-directional movement provides optimized clearance for internal components since moving the door away from the cabinet in the X direction ensures sufficient clearance for drawers, shelves, or other internal elements located near the hinge side and moving the door towards the cabinet in the Y direction could potentially optimize space utilization within the fridge by minimizing the overall swing radius needed for full access.
