Electrifying the device after the operation is finished; when the invention is just powered on, the motor 11 firstly rotates positively to drive the first gear 113 to rotate and to rotate the adjusting ring 12 through the meshing transmission of the second gear 114; the adjusting ring 13 can only move up and down relative to the upper shell 13 but can not rotate relatively by installing the fixture block 132 in the vertical sliding groove 315; the rotation of the adjusting ring 12 drives the protruding head 123 to move along an adjusting sliding groove 131 formed on the outer wall of the lifting ring 13, and since the height of the adjusting sliding groove 131 in the vertical direction is continuously changed, the adjusting ring 12 drives the lifting ring 13 to reciprocate in the vertical direction while rotating; the lifting and lowering of the lifting ring 13 causes the blades 14 to extend and retract from the barrier 33.

When the boss 123 is located at the highest position of the height of the adjustment sliding groove 131, that is, when the vane 14 is completely extended from the baffle 33, the motor 11 starts to rotate reversely; the motor 11 rotates reversely to make the face gear 112 rotate, the first gear 113 stops rotating, i.e. the lifting assembly 1 stops working and the transmission assembly 2 starts working; the blade 14 is fixed in the fully extended condition as the adjustment gear 12 is no longer rotating; the motor 11 rotates reversely to drive the forward driving gear 292 and the reverse driving gear 293 to rotate, and drives the intermittent transmission assembly 24 to rotate intermittently to drive the eccentric gear 25 to rotate; the eccentric gear 25 rotates to make the swing frame 23 swing with the center as an axis; when the swing frame 23 swings to the stroke end, the forward driving gear 292 or the reverse driving gear 293 is in meshed transmission with the second rotating gear 27, so that the forward and reverse rotation alternate function of the blade 14 is realized, and the clothes cleaning is more added.

After the motor 11 rotates reversely for a certain time, and the clothes are washed, the motor 11 rotates forward to drive the adjusting ring 12 to rotate, so that the raised head 123 moves to the lowest position along the adjusting sliding groove 131; the vanes 14 move down with the lifting ring 13 to be fully retracted into the baffle 33.

After the above operation is completed, the motor 11 rotates reversely again; at this time, the lifting member 264 in the steering assembly 26 is controlled to move upwards to the highest position along with the adjusting ring 12 driving the second transmission gear 262; so that the second transmission gear 262 is changed from the initial synchronous rotation with the central shaft 261 to the relative rotation, that is, the central shaft 261 does not rotate; at this time, the central shaft 261 stops rotating, so that the intermittent drive assembly 24 and the eccentric gear 25 do not rotate, so that the swing frame 23 does not swing, that is, the rotating direction of the blade 14 is not changed; the rotation of the blades 14 generates a centrifugal force, so that the sewage in the tub enters the blade mounting groove 312 through the water inlet pipe 34, and is discharged through the water discharge pipe 35 under the action of the centrifugal force, thereby realizing the function of discharging the sewage.

After the sewage in the barrel is basically drained, clean tap water is added, and the steps are repeated for a plurality of times, so that the clothes are cleaned.

The invention is provided with the adjusting ring 12 and the lifting ring 13, the adjusting ring 12 is driven by the motor 11 to rotate so as to drive the lifting ring 13 and the blades 14 to move up and down, and the functions of unfolding and retracting the blades 14 are realized.

In the invention, one end of the swing frame 23 is connected with an eccentric gear 25 in a transmission way, and the eccentric gear 25 rotates to drive the swing frame 23 to swing.

The invention realizes that the swing frame 23 is driven by the motor 11 to do periodic reciprocating swing by arranging the intermittent transmission assembly 24 and fixedly connecting the lower magnet 323 and the upper magnet 251 on the eccentric gear 25 and the shell 3 respectively, and can be kept for a period of time after swinging to the limit position.

The invention realizes that the blade 14 only rotates in one direction when the blade 14 is retracted and drainage action is started by arranging the control reversing assembly 26 to stop the rotation of the intermittent transmission assembly 24 when the blade 14 is fully retracted.

According to the invention, the central hole 313 is formed in the center of the blade mounting groove 312 and the water outlet hole 314 is formed in the position far away from the center, so that sewage enters the blade mounting groove 312 from the central hole 313 and is discharged from the water outlet hole 314 under the action of centrifugal force, and the function of sewage discharge is realized.

The lifting component 1 and the transmission component 2 are connected to the output end of the motor 11 in a one-way transmission mode, so that the motor 11 rotates forwards to drive the lifting component 1 to work, and rotates backwards to drive the transmission component 2 to work.
