As shown in Figure 1, during rotary drum washing machine 100 operates, flow by terminal pad 3 and 2 bottoms of inner cylinder it
Between limit runner when, by the exclusion guiding role of water repellent structure, constantly move around, while in the effect of centrifugal force
Under, flow is pushed out into the water stream channel limited between inner cylinder 2 and outer barrel 1 and constantly rises.Reference Fig. 4 and Fig. 6, due to
It is provided with outer barrel convex ribs 11 circumferentially on 1 inner peripheral surface of outer barrel, and is provided with circumferentially on the peripheral surface of inner cylinder 2
Inner cylinder convex ribs 22, flow can be commutated during rising by the blocking of outer barrel convex ribs 11 and inner cylinder convex ribs 22 suddenly,
And (such as in regions Δ H shown in Fig. 6) rolls formation office up and down in 22 region of outer barrel convex ribs 11 and interior bucket convex ribs
The rotating vortex in portion increases so as to cause the flow turbulence intensity in this region, very strong is cut in this way, being equivalent to and providing one
To plow force effect on the barrel that flow is touched, thus, it is possible to be efficiently peeled off the residue being attached on barrel, realize
The effect of clean cylinder.
Rotary drum washing machine 100 according to the ... of the embodiment of the present invention, by the peripheral surface of the inner peripheral surface of outer barrel 1 and inner cylinder 2
Outer barrel convex ribs 11 and inner cylinder convex ribs 22 are respectively set, when flow limits between inner cylinder 2 and outer barrel 1 under the influence of centrifugal force
Water stream channel rise when, can near 22 position of outer barrel convex ribs 11 and inner cylinder convex ribs generate rolling flow, wash away wall back and forth
Face, makes barrel be washed away plow effect by the high intensity of flow, washes away stripping dirt so as to high intensity, improves impeller laundry
The clean cylinder effect of machine 100.
In one embodiment of the invention, as shown in Figure 4 and Figure 6, the downsides of outer barrel convex ribs 11 is from the bottom up
Tilted towards outer barrel 1 on direction, the upper side of outer barrel convex ribs 11 is tilted towards outer barrel 1 on direction from top to bottom.Exist as a result,
