Abstract
refrigerator, comprising a cabinet, a door 20 for opening and closing the cabinet, and a hinge assembly 30 for connecting the cabinet 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 20, the first groove 321 is located in the other of the cabinet 10 and the door 20, the second shaft 312 is located in one of the cabinet and the door 20, and the second groove 322 is located in the other of the cabinet 10 and the door 20.The door 20 comprises a door gravity centre, and when the door 20 is in the opening process, the hinge assembly 30 drives the door gravity centre to move towards the cabinet. A direction from the door 20 towards the cabinet serves as a second direction Y. The cabinet includes an accommodating chamber 10, 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 20. A direction from the accommodating chamber 10 towards the outer side surface 13 serves as a first direction X. When the door 20 is opened from a closed state, the door’s gravity centre moves towards the cabinet in the second direction Y, and meanwhile, the door moves away from the cabinet in the first direction X. When the door 20 is opened from a closed state, the door 20 only rotates in situ initially, then the door’s gravity centre moves towards the cabinet in the second direction Y, and meanwhile, the door 20 moves away from the cabinet in the first direction X. Driving the door’s centre of gravity towards the cabinet when the door is opened or closed will improve the refrigerator's stability and might prevent it from toppling over.
