It solves the technical problem that the hinge structure of current washing machines is simple, and the effect and function are relatively simple, which cannot meet higher practical needs.

[0006] The above-mentioned technical problem of this utility model is solved by the following technical solution: a washing machine hinge that can automatically close the door, including a body hinge seat installed on the washing machine body and a cabinet door hinge seat installed on the door, wherein the body hinge seat and the cabinet door hinge seat are rotatably connected by a rotating shaft, and a plurality of torsion springs for automatic door closing are provided between the cabinet door hinge seat and the rotating shaft; a buffer structure is provided between the body hinge seat and the cabinet door hinge seat, and a suction closing structure is provided between the cabinet door hinge seat and the washing machine body. In this invention, the body hinge seat is installed on the washing machine body, and the cabinet door hinge seat is installed on the door. The door and the washing machine body are connected by a hinge. When the washing machine finishes its operation and the door is opened, the door will automatically spring open to 3 degrees under the action of a torsion spring, making it easy to open. The door can rotate from 0 to 100 degrees. When the door is between 80 and 100 degrees, it can be stopped at any fixed angle under the action of a buffer structure. During the closing process, the door will automatically close under the action of a torsion spring, and the door will automatically close due to the action of a suction closing structure.

[0007] Preferably, the buffer structure includes several dampers fixed on the upper and lower sides of the hinge seat of the machine body, with damping rods inside the dampers; irregularly shaped door-stopping protrusions are provided at both ends of the rotating shaft, and the damping rods abut against the surfaces of the door-stopping protrusions. The machine door can rotate from 0 to 100 degrees, and can be stopped at any fixed angle between 80 and 100 degrees. When the door hinge seat rotates between 80 and 100 degrees, the damping rods abut against the door-stopping protrusions, and the compression of the damping rods achieves the effect of stopping the door at any angle.

[0008] Preferably, a lug is fixed to one side of the damper, and a bolt hole is provided on the lug. The lug and bolt hole on the surface of the damper are used to fix and install the damper, and their position or angle can also be adjusted according to the actual situation.

[0009] Preferably, the door stop protrusion is a smooth-surfaced camshaft structure. The door can rotate from 0 to 100 degrees. Between 80 and 100 degrees, the door can be stopped at any fixed angle. When the door hinge seat rotates between 80 and 100 degrees, the damping rod abuts against the camshaft structure surface at both ends of the rotating shaft, and the compression of the damping rod achieves arbitrary door stopping. When the door is closed to 80 degrees, the camshaft structure at both ends of the rotating shaft rotates, the damping rod is released from compression, and the door automatically closes under the action of the torsion spring. Furthermore, when the door is closed to 40 degrees, the damping rod and camshaft structure will provide another buffering effect.

[0010] Preferably, one end of the torsion spring is sleeved on the rotating shaft, and the other end of the torsion spring is fixed to the door hinge seat.

[0011] Preferably, the suction-closing structure includes several magnetic blocks embedded in the door hinge seat and the body hinge seat. When the door is closed to about 3 degrees, the magnetic blocks embedded in the door hinge seat and the body hinge seat attract each other, achieving the effect of automatic suction-closing.

[0012] Preferably, the magnetic block embedded in the hinge seat of the machine body is higher than the surface of the hinge seat. The hinge seat of the door has a corresponding groove and a built-in magnetic block, and the magnetic block embedded in the hinge seat of the machine body is higher than the surface of the hinge seat of the machine body. When the door is closed to about 3 degrees, the two magnetic blocks attract and close the door.

[0013] Preferably, the body hinge seat and the door hinge seat are provided with a plurality of mounting holes. The body hinge seat is installed on the body of the washing machine and the door hinge seat is installed on the door through the mounting holes.

[0014] Therefore, the washing machine hinge of this utility model that can automatically close the door has the following advantages: it has an automatic door closing effect, and has different effects at different opening angles and positions, which can meet higher and more practical needs and greatly optimize the user experience.
