And produce following effect, even if that is, will appear from washings curling winding and can also release the winding.In contrast, in the song
The inner side of line (bending), by direction (in FIG for the clockwise) rotation pointed by impeller 4 towards the curve, produces court
Inner side pulls the power of washings.Based on this two strands towards outside and the power of the different directions towards inner side, washings are by push-and-pull
And prevent winding, while being extruded washing.Based on such function, it is obtained in that and only clean by stirring the height that cannot be obtained
Power.
In above-mentioned washing machine, have and the disjunct independent projections of multiple blade convex tendon 4c in the central part of impeller 4
Portion 4d.Peripheral speeds of the jut 4d when impeller 4 rotates is less.On the other hand, it is present in than the jut 4d more
It is larger by the peripheral speeds of multiple blade convex tendon 4c when impeller 4 rotates of the outer circumferential side of impeller 4.It is present in than jut 4d more
There is mixing power to washings and washings by multiple blade convex tendon 4c of the outer circumferential side of impeller 4.On the other hand, exist
Hardly there is the mixing power to washings and washings in the jut 4d of the central part of impeller 4.Based on such structure,
When impeller 4 rotates, because washings are screwed between jut 4d and multiple blade convex tendon 4c, rub and wash, therefore, it is possible to base
Higher cleaning strength is obtained in this.
Additionally, in above-mentioned washing machine, there are multiple low-lying portion 4e in the outer surface portion of the above-mentioned jut 4d of impeller 4.
