The washing machine of this embodiment is provided with the staving valve plug in the bottom of interior bucket, and the washing water only exists inside the interior bucket when washing, does not have water between the inside and outside bucket. The outer tub is provided with a drain valve assembly for controlling the discharge of the washing water and collecting the washing particles. During washing granule exists the drain valve, and washing end push rod mechanism pushes away the staving valve plug, and the drain valve keeps closing this moment, and between washing water entered into interior outer bucket, washing granule released in the drain valve between interior outer bucket under the effect of rivers, reached and predetermine behind the water level push rod structure and withdraw, the staving valve plug closes once more. At the moment, the inner barrel is rotated to clean particles, and the inner barrel wall and the outer barrel wall are collided under the action of water flow, so that the operation of cleaning the inner barrel and the outer barrel is completed.
Although the present invention has been described with reference to a preferred embodiment, it should be understood that various changes, substitutions and alterations can be made herein without departing from the spirit and scope of the invention as defined by the appended claims.
Claims (10)

5. A control method of a washing machine as claimed in any one of claims 1 to 4, characterized in that the washing machine controls the inner tub to drain until a set water level is reached in the water collecting device, stops the inner tub from draining and controls the inner tub to rotate to agitate water in the water collecting device to move cleaning particles between the inner tub and the water collecting device to perform a self-cleaning process.
6. The control method of a washing machine according to claim 5, wherein the water collecting device is connected to a drain line communicated with the water collecting chamber, and a drain valve is provided on the drain line;
the washing machine controls the drainage valve to be closed, the push rod pushes the sealing mechanism to open the drainage port to drain water from the inner barrel, and when the water in the water collecting device reaches a set water level, the inner barrel is controlled to stop draining water.
7. The control method of a washing machine as claimed in claim 6, wherein the washing machine controls the drain valve to be kept in a closed state after the water in the water collecting device reaches a set water level, controls the inner tub to rotate, and stops the inner tub from rotating when the inner tub rotates for a set time T0;
preferably, the inner barrel rotates continuously/discontinuously in one direction/in two directions.
8. The control method of the washing machine as claimed in claim 7, wherein after the inner tub stops rotating, the washing machine controls the drain valve to open, the push rod pushes the sealing mechanism open the drain port to drain the water from the inner tub until all the water in the inner tub is drained.
