Preferably, the first openings 721 are located at both ends of the hinge shaft 72.

In an embodiment, the hinge shaft 72 and the hinge seat 71 may be integrally formed, the hinge seat 71 may be understood as a mounting seat mounted on the washing machine cabinet, and the second opening 711 is located at a side facing away from the hinge shaft 72, i.e., facing the washing machine cabinet. The hinge shaft 72 is a hollow shaft, and is non-rotatable with respect to the hinge base 71. Both ends of the hinge shaft 72 are hinged to the door ring 50.

In another embodiment, the hinge shaft 72 and the hinge base 71 can be two separate parts, the hinge base 71 is provided with a mounting through hole for the hinge shaft 72, the hinge shaft 72 is located in the mounting through hole, the hinge shaft 72 can rotate in the mounting through hole, two ends of the hinge shaft 72 protrude out of the mounting through hole, and the protruding part is used for hinging the door ring 50.

The water passage pipe and the circuit line pass through the first opening 721 and the second opening 711. That is, the hinge seat and the hinge shaft can be contained in or can pass through an electric wire and a water pipe.

The door ring 50 is hinged at a hinge axis 72. Preferably, the end of the door ring 50 is hinged to the hinge shaft, and the door ring 50 can be connected to the door body of the washing machine and/or the heavier component of the door body of the washing machine after being hinged to the hinge shaft.
