Step S10, judging whether the rotation of the inner barrel reaches the preset time;
Step S11, if the judgment result is yes, returning to the step S9, and if the judgment result is no, controlling the opening of the drain valve;
step S12, the push rod drives the motor to act, the push rod is released again, and the valve plug of the barrel body is pushed up again to drain water;
step S13, judging whether the water level in the water collecting device is smaller than a preset water level or not;
Step S14, if the judgment result is yes, controlling a push rod driving motor to act, accommodating the push rod, plugging the inner barrel by the barrel valve plug, and if the judgment result is no, returning to the step S12;
Step S15, washing is finished.
The washing machine of this embodiment is provided with staving valve plug in the bottom of interior bucket, and the washing water only exists in interior bucket inside when washing, does not have water between interior bucket. The outer tub is provided with a drain valve assembly for controlling the discharge of the washing water and collecting the washing particles. In washing the granule existence drain valve during the washing, washing end push rod mechanism pushes the staving valve plug open, and the drain valve keeps closing this moment, and washing water enters into between the inside and outside bucket, and washing granule is released to between the inside and outside bucket from the drain valve under the effect of rivers, reaches the push rod structure and withdraws after predetermineeing the water level, and the staving valve plug closes again. At this time, the cleaning particles of the inner barrel are rotated to collide with the walls of the inner barrel and the outer barrel under the action of water flow, so that the operation of cleaning the inner barrel and the outer barrel is completed.
The foregoing description is only illustrative of the preferred embodiment of the present invention, and is not to be construed as limiting the invention, but is to be construed as limiting the invention to any simple modification, equivalent variation and variation of the above embodiments according to the technical matter of the present invention without departing from the scope of the invention.
