- the amount of cleaning particles can be increased or decreased according to the user's demand. At this time, the amount of cleaning particles is no longer fixed, and the washing machine needs to re-determine the amount of cleaning particles.
- the cleaning particles in the space are replaced before and after.
- the water level corresponding to the same concentration will also change, and the cleanliness of the inner and outer barrel walls of the drainage process of the present invention is not only related to the rotational speed set by the inner tub, but also to the concentration of the cleaning particles at the water level. Therefore, the present invention controls the rotation speed of the inner tub according to the change of the concentration of the cleaning particles, and combines the two to control the cleaning of the inner and outer barrel walls by the cleaning particles.
