Abstract

refrigerator with a switchable hinge assembly, comprising: a cabinet, a door for opening and closing the cabinet, and the hinge assembly 30 for connecting the cabinet and the door. The hinge assembly 30 comprises a plurality of hinge parts 31, 32 and a switching assembly 40. When the door is in an opening process, the switching assembly 40 controls the plurality of hinge parts 31, 32 to successively operate in a first sequence, and when the door is in a closing process, the switching assembly 40 controls the plurality of hinge parts 31, 32 to successively operate in a second sequence, and the first sequence is opposite to the second sequence. The hinge assembly comprises a first hinge part 31 and a second hinge part 32, the switching assembly 40 is connected with the first hinge part 31 and the second hinge part 32, the first hinge part 31 is fixed to the cabinet, and the second hinge part 32 is fixed to the door. When the door is in the opening process, the first hinge part 31 moves relative to the switching assembly 40 first, and then, the second hinge part 32 moves relative to the switching assembly 40. When the door is in a closing process, the second hinge part 32 moves relative to the switching assembly 40 first, and then, the first hinge part 31 moves relative to the switching assembly 40. The switching assembly comprises a first fitting part 41 and a second fitting part 42. When the door is opened from a closed state to a first opening angle, the first hinge part 31 and the first fitting part 41 move relatively, and the second fitting part 42 limits the second hinge part 32. When the door is continuously opened from the first opening angle to a second opening angle, the second hinge part 32 is released from the limit of the second fitting part 42, and the first fitting part 41 limits the first hinge part 31. When the door is continuously opened from the second opening angle to a maximum opening angle, the second hinge part 32 and the second fitting part 42 move relatively, the first hinge part 31 and the first fitting part 41 move relatively by a first shaft set 311, 312 and a first groove set 411, 412 which are fitted with each other, and the second hinge part 32 and the second fitting part 42 move relatively by a second shaft set 321 and a second groove set 422 which are fitted with each other. The described refrigerator provided with a switching hinge assembly improves the degree of freedom of the opening and closing of the door body (20), and may generate a variety of motion tracks to adapt to different application scenarios.
