In this embodiment, each drainage channel 32 is formed by a hollow rib protruding from the inner side surface of the inner cylinder bottom 102, and the hollow rib lifts and beats water flow and clothes in the inner cylinder 1 in the rotation process of the inner cylinder 1 to wash the clothes, so that the inward protruding drainage channel 32 has the function of assisting in lifting and beating the clothes in the inner cylinder 1.

In this embodiment, the drainage channel 32 and/or the drainage pipe 31 is provided with a drainage pump 33, so as to apply pressure to the water flow flowing to the inner tub bottom 102 of the washing machine, and discharge the water flow to the outside of the washing machine along the drainage channel 32 and the drainage pipe 31, and the drainage pump 33 is turned on when the drum washing machine is in a normal washing state and does not work and the drum washing machine executes a drainage program, so as to control the discharge of the water flow in the inner tub of the washing machine and provide a water flow driving force.

EXAMPLE III

In this embodiment, a drainage method for a washing machine is described based on the second embodiment, where the inner cylinder rotates at a certain rotation speed, so that washing water in the inner cylinder flows toward the large opening end by adhering to the inner wall of the tapered inner cylinder under the action of centrifugal force, and flows out of the washing machine along a drainage channel arranged at the large opening end when flowing to the large opening end of the inner cylinder, and flows out of the washing machine along a drainage pipe, thereby realizing the drainage of the washing water in the inner cylinder.

By the method, water flow in the inner barrel is not influenced by centrifugal force and does not converge and flow towards the large opening end of the inner barrel in the normal washing state of the washing machine, water flow in the inner barrel in the high-speed rotation of the inner barrel is influenced by centrifugal force and flows towards the drainage flow channel at the large opening end of the inner barrel and is discharged outside in the drainage state of the washing machine, so that water contained in the inner barrel cannot flow out from the drainage opening when the inner barrel normally rotates, the effects of sealing the inner barrel in the rotation process of the inner barrel and opening the normal discharge of the water contained in the inner barrel by the drainage valve in the drainage process are further realized, and the purpose of normal drainage of the washing machine with double effects of rotation of the inner barrel and water containing is achieved.

In this embodiment, the specific draining steps of the draining method of the washing machine are as follows,

In this embodiment, in step 3, the drainage pump on the drainage channel and/or the drainage pipe starts to work to apply pressure to the water flow flowing to the bottom of the inner tub, so that the water flows along the drainage channel and the drainage pipe and is drained to the outside of the washing machine. When the washing machine executes other programs, the drainage pump on the drainage flow channel and/or the drainage pipe does not work, so that water in the inner barrel is not adsorbed and discharged by the drainage pump, and the water in the inner barrel is retained to wash clothes normally.

In the embodiment, in the drainage process of the washing machine, the inner barrel rotates at a medium-high speed, so that the water in the inner barrel is attached to the side wall of the inner barrel under the action of centrifugal force and flows towards the large opening end of the inner barrel.

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.
