At the nozzle position of corresponding first ventilation pipe 20.
In embodiments of the present invention, the air supply plant is used to the air at the second air inlet 321 being sent to venthole 12
Place；The air supply plant can be set in the first ventilation pipe 20, also can be set at the second air inlet 321, or also
It can be set outside washing tub, be connected to using pipeline with the second air inlet 321, it is not limited in the embodiment of the present invention, this
Field technical staff can be configured according to the actual situation.The air supply plant can be air pump or fan etc., the present invention
Embodiment to this also without limitation.
Referring to fig. 1 and fig. 2, the first ventilation pipe 20, the bottom surface of washing tub and impeller 10 surround a relative closure
Cavity, outside air is sent into the cavity by air supply plant from the second air inlet 321 on the bottom surface of washing tub, air stream
One-way check valve 40 is crossed, is then entered via the first air inlet 13 on impeller 10 in the cavity 11 of impeller 10, finally by wave
The venthole 12 for taking turns 10 surfaces, which enters in washing water, forms bubble, since the venthole 12 of the impeller 10 in washing process can be to
A large amount of bubbles are exported in washing water, bubble contacts with cleaning solution water and is easy to produce foam, and the utilization of cleaning solution can be improved in this way
Rate enhances the clean ability of rotary drum washing machine.Meanwhile clothing is washed using bubble impact, it can be further improved washing for clothing
Net degree, while reducing clothing winding.
Optionally, refering to what is shown in Fig. 1, the rotary drum washing machine further includes the wave wheel rotary shaft 50 connecting with impeller 10；Impeller
Shaft 50 is located in the first ventilation pipe 20；The air supply plant is fan leaf 61, and fan leaf 61 and wave wheel rotary shaft 50 are solid
Determine and is located at 40 downside of one-way check valve；When wave wheel rotary shaft 50 drives impeller 10 to rotate, fan leaf 61 can be by the second air inlet
Air at mouth 321 is sent at venthole 12.
Refering to what is shown in Fig. 1, since fan leaf 61 and wave wheel rotary shaft 50 are fixed, thus when wave wheel rotary shaft 50 drives impeller 10
When rotation, fan leaf 61 is also rotated with the rotation of wave wheel rotary shaft 50, and at this moment fan leaf 61 can be by outside air from second
Air inlet 321 sucks, and is then blowed at venthole 12 again.In this embodiment, since fan leaf 61 does not need additional drive
Dynamic device, thus reduce number of components, save cost.In practical applications, wave wheel rotary shaft generally is driven using motor 80
50 rotations.
It should be noted that rotary drum washing machine in the prior art is when washing clothing, wave wheel rotary shaft 50 will not only be driven
Impeller 10 does positive direction rotation, also impeller 10 to be driven to do opposite direction rotation, achievees the purpose that clean clothing with this.Due to wind
Machine flabellum 61 and wave wheel rotary shaft 50 are fixed, thus fan leaf 61 will also do positive direction rotation and opposite direction rotation, in the present invention
