A washing machine as claimed in claim 6, characterized in that: the water containing barrel is connected with a washing machine driving motor so as to drive the water containing barrel to rotate under the action of the driving motor, and further, clothes and washing water contained in the water containing barrel are stirred; the washing machine is provided with a positioning device to be stopped at a fixed position when the water containing barrel stops rotating; when the water holding barrel is fixed to the fixed position, the water outlet end of the siphon flow channel and the water inlet of the auxiliary water inlet pipe are arranged in a corresponding mode at intervals, and therefore water flow sprayed by the auxiliary water inlet pipe directly flows into the siphon flow channel from the water outlet end.

8. A washing machine as claimed in claim 7, characterized in that: the water containing barrel is a barrel-shaped structure with an open top end and a vertically arranged axis, the water containing barrel is a conical barrel with the barrel diameter gradually enlarged from bottom to top, and a circle of dewatering holes arranged at intervals are arranged at the top end of the water containing barrel.

9. A washing machine as claimed in claim 5, characterized in that: the first flow passage and the second flow passage of the siphon flow passage extend along the direction of any construction line of the water containing barrel; the top parts of the first flow channel and the second flow channel extend to the top end of the side wall of the water containing barrel and are communicated through a communication hole;

preferably, the lower end of the first flow passage extends to a position close to the bottom of the tub and is provided with an opening to form a water inlet end, so that the washing water inside the tub flows into the siphon flow passage through a gap between the lower end of the first flow passage and the bottom of the tub and the opening provided at the water inlet end.

10. A washing machine as claimed in any one of claims 1 to 9, characterized in that: a groove-shaped fixing part is arranged below the water containing barrel to contain the washing water discharged from the siphon runner; the bottom of the fixing part is communicated with a drain pipe of the washing machine so as to discharge the contained washing water;

preferably, the water inlet of the auxiliary water inlet pipe is correspondingly arranged on the fixing part, and the water inlet is correspondingly arranged below the water outlet end of the siphon runner when the water containing barrel rotates to the fixed position.
