After the clothes are put in, the driving motor 191 drives the rotating shaft 192 to rotate, the rotating shaft 192 drives the opening and closing driven wheel 151 and the lifting driving wheel 196 to rotate simultaneously, the opening and closing driving wheel 195 is firstly connected with the opening and closing driven wheel 151 to rotate so as to drive the fan blades 17 to rotate and close the opening 111, at the moment, the second notch 1952 on the lifting driving wheel 196 corresponds to the lifting shaft 115, after the fan blades 17 close the opening 111, the first notch 1951 of the opening and closing driving wheel 195 rotates to one side close to the opening and closing driven wheel 151, so that the fan blades 17 stop rotating, the lifting shaft 115 is in threaded connection with the lifting driving wheel 196 while the fan blades 17 stop rotating, the lifting driving wheel 196 rotates relative to the lifting shaft 115, so that the fan blades 17 axially move along the lifting shaft 115 and are flush with the opening 111, and at the moment, the closing action is completed. When the clothes need to be taken out through the opening 111, the rotating shaft 192 is driven in the reverse direction to drive the opening/closing driven wheel 151 and the lifting driving wheel 196 to rotate in the reverse direction, that is, the fan blades 17 are made to axially move in the reverse direction along the lifting shaft 115 to be staggered with the opening 111 by a certain height, and then the fan blades 17 are made to rotate to expose the opening 111, so that the interference of the fan blades 17 by the inner wall of the opening 111 is avoided when the fan blades 17 rotate.

Referring to fig. 9, fig. 9 is a schematic flow chart of a control method of a door body assembly according to an embodiment of the present application.

The embodiment of the application also provides a control method of the door body assembly suitable for the washing machine, wherein the washing machine comprises a door body provided with an opening, fan blades and a driving motor, the fan blades can rotatably seal or expose the opening, and the driving motor can drive the fan blades to rotate.

It is understood that the control method of the door assembly in the present embodiment can be applied to clothes processing equipment such as clothes dryers, washing and drying integrated machines, etc., and the washing machine is taken as an example in the present embodiment.

The washing machine comprises a door body assembly, and the structure of the door body assembly can refer to the door body assembly in any one of the embodiments, and is not described herein again.

Optionally, the control method further includes: and if the current is within the preset current range, normally closing the door.

It should be noted that, after the current of the driving motor is detected to be outside the preset current range, the driving motor may be stopped first, and then the driving motor may rotate in the second direction, that is, the motor may be stopped and then reversed, and the motor may be reversed by stopping the driving motor to serve as a buffer, so as to avoid a fault.

It can be understood that the current of the driving motor is outside the preset current range under various conditions, and most of the conditions are that the fan blades clamp the clothes when rotating to close the opening, so that the opening cannot be completely closed due to interference of the fan blades by the clothes, the resistance of the driving motor is increased, and then the current is abnormal. When the current of the driving motor is out of the preset current range, namely the current is abnormal, the driving motor rotates reversely to expose the opening, so that a user can remove obstacles or remove clothes interference by rotating the fan blades, and a door closing command can be executed again.

Further, in order to solve the problem of clothes being clamped by the rotation of the fan blades, in this embodiment, the washing machine further includes an inner tub and clothes, when the clothes are clamped by the fan blades, the current of the driving motor is outside the preset current range, and after the driving motor is driven to rotate along the second direction, the control method of the door assembly further includes:
