In the above technical solution, when a user starts the washing machine to wash the laundry, the washing machine starts to feed water, when the water level monitor detects that the water level reaches a predetermined water level, the controller controls the motor to start a shaking inner tub program (start the motor and drive the inner tub to rotate for 1s to stop for 4s, thereby achieving a shaking effect, and also performing a shaking manner of forward rotation, stop and reverse rotation), thereby floating all the cleaning balls, and starting a normal washing and dewatering program after the time for shaking the inner tub reaches a first set time (for example, the first set time is set to 20s, 30s or other time according with the user's needs), wherein the values of N1 and N2 are set according to the actual use needs of the washing machine, and preferably, the rotation for 1s to stop for 4 s.

Through before washing machine washes, shake the washing machine inner tub, can float the whole entering of cleaning ball between inner tub and outer bucket, prevent that cleaning ball card from in heating pipe or other parts or gap, and then promote the clean effect of interior outer bucket.

Preferably, in step S2, the drainage procedure is:

and S21, starting the motor while draining water.

When the drainage, because the dirty material can deposit, deposit the dirty material in the washing machine bottom can be more and more along with the decline of water level in drainage process, often can lead to the dirty material to stay in the washing machine bottom after the drainage like this, and then influence clean effect, consequently, in order to avoid this kind of condition, start the motor simultaneously and interior bucket at the drainage, let the clean ball move, interior bucket will stir the water in the washing machine like this and discharge all dirty materials to the clean ball also can be along with the activity and then better clean interior outer bucket.

In order to further improve the cleaning effect of the cleaning balls during water drainage of the washing machine, different motor rotating speeds can be set according to different current water levels, the lower the water level in the inner barrel, the lower the moving speed of the cleaning balls, therefore, along with the reduction of the water level of the inner barrel, the rotating speed of the motor needs to be increased to increase the activity of the cleaning balls, and thus the cleaning effect of the cleaning balls during the water drainage process can be improved.

Preferably, the step S214 specifically includes:

When the last step of rotation time reaches a second set time (for example, 120s), the dewatering process is started after the drainage is considered to be finished

s408, judging whether the current water level of the inner barrel is A3 which is more than M and less than or equal to A2, if so, entering the step S409, otherwise, entering the step S410;

s409, after the motor rotates for 3S and stops for 4S, returning to the step S408;

s410, when the current water level of the inner barrel is M not more than A3, the motor is turned for 2S and stopped for 4S;
