Below with reference to Fig. 1-Fig. 6, the rotary drum washing machine 100 according to this utility model embodiment is described.

As it is shown in figure 1, according to the rotary drum washing machine 100 of this utility model embodiment, including: outer barrel 1 and inner core 2.

Specifically, as it is shown in figure 1, the outer barrel 1 staving shape that (the such as top of the outer barrel 1 shown in Fig. 1) is unlimited in top Shape, the inner peripheral surface of outer barrel 1 is formed with in outer barrel 1 (the such as direction towards outer barrel 1 central axis shown in Fig. 4) protruding Outer barrel convex tendon 11, outer barrel convex tendon 11 is circumferentially extending along outer barrel 1, and outer barrel convex tendon 11 includes one or is spaced along the vertical direction That arranges is multiple, say, that can only arrange on the inner peripheral surface of outer barrel 1 one along the circumferentially extending outer barrel convex tendon 11 of outer barrel 1, Multiple outer barrel convex tendon 11 circumferentially extending along outer barrel 1 can also be set on the inner peripheral surface of outer barrel 1, and multiple outer barrel convex tendon 11 is along outward Axis direction (the such as above-below direction shown in Fig. 2) interval of bucket 1 is arranged.

As shown in Figure 1-Figure 3, inner core 2 is rotatably provided in outer barrel 1, and the bottom of inner core 2 is provided with drying structure, inner core 2 Outer peripheral face on be formed with the inner core convex tendon 22 towards outer barrel 1 projection, inner core convex tendon 22 is circumferentially extending along inner core 2, and inner core is convex Muscle 22 includes one or the most spaced apart multiple.It is to say, can only arrange one on the outer peripheral face of inner core 2 Along the inner core convex tendon 22 that inner core 2 is circumferentially extending, the outer peripheral face of inner core 2 can also be arranged multiple along inner core 2 circumferentially extending in Cylinder convex tendon 22, and multiple inner core convex tendon 22 is along axis direction (the such as above-below direction shown in Fig. 2) the interval setting of inner core 2.

As it is shown in figure 1, during rotary drum washing machine 100 operates, current at the bottom of by connection dish 3 and inner core 2 it Between limit runner time, by the exclusion guide effect of drying structure, constantly to moving around, simultaneously in the effect of centrifugal force Under, current are pushed out to the water stream channel limited between inner core 2 and outer barrel 1 and constantly rise.Reference Fig. 4 and Fig. 6, due to It is provided with outer barrel convex tendon 11 circumferentially on outer barrel 1 inner peripheral surface, and is provided with circumferentially on the outer peripheral face of inner core 2 Inner core convex tendon 22, current can be commutated suddenly by the stop of outer barrel convex tendon 11 and inner core convex tendon 22 during rising, And formation office of rolling up and down (such as in the Δ H region shown in Fig. 6) in outer barrel convex tendon 11 and interior bucket convex tendon 22 region The rotating vortex in portion, thus cause the current turbulence intensity in this region to increase, so, be equivalent to provide cuts the strongest Act on the barrel that current are touched to plow power, thus, it is possible to be efficiently peeled off the residue being attached on barrel, it is achieved The effect of clean cylinder.

Rotary drum washing machine 100 according to this utility model embodiment, by the inner peripheral surface of outer barrel 1 and the periphery of inner core 2 Outer barrel convex tendon 11 and inner core convex tendon 22 it is respectively provided with, when current limit along between inner core 2 and outer barrel 1 under the influence of centrifugal force on face When the water stream channel made rises, rolling current can be produced near outer barrel convex tendon 11 and inner core convex tendon 22 position, backwash Brush wall, makes barrel be washed away plow effect by the high intensity of current, such that it is able to high intensity washes away stripping dirt, improves impeller The clean cylinder effect of washing machine 100.

In an embodiment of the present utility model, as shown in Figure 4 and Figure 6, the downside of outer barrel convex tendon 11 is from lower past On direction on tilted towards outer barrel 1, the upper side of outer barrel convex tendon 11 is tilted towards outer barrel 1 on direction from top to bottom.By This, during current rise, current can be guided to inner core 2 side by the upper side of outer barrel convex tendon 11 and downside effectively To, make current can effectively wash away barrel, thus realize the purpose of clean cylinder.Process further, it is also possible to be easy to outer barrel convex tendon 11 Molding, the structure making outer barrel convex tendon 11 is simpler rationally.

Further, with reference to Fig. 4 and Fig. 6, on the cross section through outer barrel 1 axis, the upper side of outer barrel convex tendon 11 and under Side all arcs in evagination.Thus, it is possible to further enhance the turbulence intensity of the current flowing through outer barrel convex tendon 11, strengthen cylinder Wall wash away plow effect, improve clean cylinder effect, the structure making outer barrel convex tendon 11 is more reasonable.

Preferably, with reference to the inner peripheral surface arc transition of Fig. 4 and Fig. 6, the upper side of outer barrel convex tendon 11 and outer barrel 1, outer barrel is convex The inner peripheral surface arc transition of the downside of muscle 11 and outer barrel 1, outer barrel convex tendon 11 inner outer barrel convex tendon 11 upper side and under Side is connected and in arc transition.Thus, it is possible to further enhance the turbulence intensity of the current flowing through outer barrel convex tendon 11, it is right to strengthen Barrel wash away plow effect, improve clean cylinder effect, further, it is also possible to make the structure of outer barrel convex tendon 11 more reasonable.

In an embodiment of the present utility model, with reference to Fig. 4 and Fig. 6, the surface of inner core convex tendon 22 is through outer barrel 1 axle Circular shape in evagination on the cross section of line, and the upper edge on inner core convex tendon 22 surface and lower edge all with the outer surface circular arc of inner core 2 Transition.Thus, it is possible to strengthen the turbulence intensity of the current flowing through inner core convex tendon 22 position, improve clean cylinder effect, make inner core convex tendon The structure of 22 is more reasonable.
