Abstract

door-opening-assisted embedded refrigerator, comprising a cabinet, a door for opening and closing the cabinet, and a hinge assembly 30 for connecting the cabinet and the door. The cabinet comprises a rear wall and an opening which are provided opposite to each other, and a direction from the rear wall towards the opening serves as a first direction. The hinge assembly comprises a first hinge part 31, a second hinge part 32 and a switching assembly 40 connected with the first hinge part 31 and the second hinge part 32. The first hinge part 31 is fixed to the cabinet, the second hinge part 32 is fixed to the door, and the switching assembly 40 comprises a first fitting part and a second fitting part. The first hinge part 31 and the first fitting part 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 move relatively by a second shaft set 321 and a second groove set which are fitted with each other. The first shaft set comprises a first shaft 311 and a second shaft 312, the first groove set comprises a first groove 411 fitted with the first shaft 311 and a second groove 412 fitted with the second shaft, the second shaft set comprises a third shaft and a fourth shaft, and the second groove set comprises a third groove fitted with the third shaft and a fourth groove fitted with the fourth shaft. When the door is in an opening process, the second fitting part limits the second hinge part and the first hinge part moves relative to the switching assembly, and then the first fitting part limits the first hinge part 31 and the second hinge part 32 moves relative to the switching assembly40. The hinge assembly 30 drives the door to rotate in situ relative to the cabinet, then drives the door to move away from the cabinet in the first direction, and then drives the door to continuously rotate in situ. The door-opening-assisted embedded refrigerator 100 can increase an opening-closing freedom degree of the door 20, and can adapt to different application scenarios.
