It can be understood that the arrangement of the rib, the groove and the assembling position in the embodiment can be replaced mutually to realize matching.

When the washing machine with keg impeller 220 of this application need be adopted and the clothes are washd: for example, when the tub 10 is used to wash the laundry, the tub 210 and the keg impeller 220 are removed from the tub 50, and then the washing is performed by a normal pulsator washing machine. Specifically, the first output shaft 310 and the second output shaft 320 can be controlled to rotate to drive the big barrel 10 and the big barrel wave wheel 50 to rotate respectively, and the rotation directions of the big barrel 10 and the big barrel wave wheel 50 are controlled to be opposite, so that the washing of the clothes in the big barrel 10 is completed; when the clothes in the tub body 10 need to be dehydrated, the rotation directions of the tub body 10 and the tub impeller 50 are the same by controlling the first output shaft 310 and the second output shaft 320 to rotate, and the clothes in the tub body 10 are dried by the centrifugal force, so that the dehydration operation of the clothes in the tub body 10 is completed. It is noted that the vat body 10 can be implemented with reference to the vat body 10 of the prior art. It should be noted that how to control the rotation direction of the tub body 10 or the tub pulsator 50 to wash and dewater can be realized by referring to the prior art. For example, when the keg barrel body 210 needs to be used for cleaning clothes therein, after the keg barrel body 210 is mounted on the vat wave wheel 50, the second output shaft 320 and the third output shaft 330 are controlled to rotate, the second output shaft 320 drives the keg barrel body 210 to rotate through the vat wave wheel 50, the third output shaft 330 drives the keg wave wheel 220 to rotate, so that the rotation direction of the keg wave wheel 220 is opposite to the rotation direction of the keg barrel body 210, thereby realizing the effect of strongly stirring water flow in the keg barrel body 210 and completing the cleaning operation of the clothes in the keg barrel body 210. When the clothes in the keg barrel body 210 need to be dehydrated, the rotation directions of the keg barrel body 210 and the keg impeller 220 are the same by controlling the second output shaft 320 and the third output shaft 330 to rotate, and the clothes in the keg barrel body 210 are dried through the action of centrifugal force, so that the dehydration operation of the clothes in the keg barrel body 210 is completed. Of course, the specific control method is not limited to this, and other cleaning methods known in the art may be used, and only the keg barrel body 210 and the keg impeller 220 need to be used as a whole as a common impeller washing machine to control the washing.

It can be understood that the keg barrel body 210 is detachably disposed on the large barrel pulsator 50. Thus, the keg is convenient to disassemble. For example, the manner of detachably coupling the keg barrel body 210 to the vat pulsator 50 may include, but is not limited to, snapping, screwing, binding, nesting, and the like.

So, can improve the upset angle of handle 410, the user of being convenient for is carried from each angle and is taken supplementary washtub 200, facilitates the use. The location of the ledge 420 is adjacent the opening of the keg barrel body 210 and it will be appreciated that the location of the ledge 420 may be internal to the keg barrel body 210 and that such an arrangement saves keg installation volume; or the position of the lug 420 is located outside the keg barrel body 210 so as to prevent the lug 420 from affecting the operation of the user when the user places the laundry in the keg barrel body 210. Moreover, the two lugs 420 are oppositely arranged along the radial direction of the keg barrel body 210 (when the keg barrel body 210 is lifted due to asymmetric arrangement, the plane of the opening of the keg barrel body 210 is inclined relative to the horizontal plane, so that the keg barrel body 210 is easily damaged), and thus, the handling of the keg barrel body 210 can be facilitated.

In an embodiment of the present application, the handle 410 includes a lifting portion 411 and rotating shafts 412 disposed at two ends of the lifting portion 411, and the rotating shafts 412 and the lifting portion 411 are integrally formed; generally, the lifting part 411 is roughly arranged in a semicircular ring shape, and the semicircular ring shape can be matched with the contour of the keg barrel body 210 when the lifting part 411 is horizontally placed, so that the lifting part 411 is convenient to place. In another embodiment, the rotating shaft 412 is detachably connected to the lifting portion 411. When the lifting part 411 is separately provided, a hole for connecting with the rotation shaft 412 should be further provided on the lifting part 411, and the rotation shaft 412 may be a bolt, and the rotation connection between the lifting part 411 and the lug 420 is realized by the mutual connection between the bolt and the rotation hole 421.

On one hand, when the small barrel body 210 is assembled with the large barrel impeller 50, the water disturbance ribs 51 need to be ensured to be well connected with the assembling grooves 211 of the small barrel body 210; on the other hand, the effect of water disturbance needs to be considered, so that the top surface 511 of the water disturbance rib 51 forms a first water disturbance area 5111 for matching with the assembly groove 211 and a second water disturbance area 5112 for disturbing water, and the first water disturbance area 5111 is sunken to form a yielding space, so that the bottom wall of the assembly groove 211 of the keg barrel body 210 needs to be protruded to form an adaptive part, and the adaptive part is accommodated in the yielding space. It should be noted that, when the keg barrel body 210 is detached from the vat pulsator 50, the first water disturbing area 5111 is relatively concave, and when a rotational flow is formed when the vat pulsator 50 rotates, it is easy to guide water to the middle portion of the vat barrel body 10 or a portion close to the barrel wall, so that the laundry can be contacted with water in a larger space, and thus washed, and when water is thrown, the laundry is also convenient to be quickly close to the barrel wall due to the guide of the first water blocking area, and the water throwing speed is increased.

Referring to fig. 24, in an embodiment of the present application, the water-disturbing ribs 51 further include two rib side surfaces 512 disposed opposite to each other, the rib side surfaces 512 of the water-disturbing ribs 51 connect the top surface 511 and the washing surface 52, and a distance between the rib side surfaces 512 of the two water-disturbing ribs 51 gradually decreases from the washing surface 52 to the top surface 511. In this embodiment, it is understood that the washing tub structure 1000 has an up-down direction parallel to the rotation axis 412, and the distance between the two rib side surfaces 512 of the water-disturbing ribs 51 gradually decreases from top to bottom in the up-down direction, and the two rib side surfaces 512 of the water-disturbing ribs 51 are substantially tapered in a vertical section (the vertical section extends in the up-down direction and is perpendicular to the horizontal plane), so as to increase the contact area between the water-disturbing ribs 51 and the assembly groove 211, thereby improving the connection effect between the small tub body 210 and the large tub pulsator 50, and to easily guide water to the middle portion of the large tub body 10 or a portion near the tub wall when the large tub pulsator 50 rotates to form a swirling flow, thereby allowing the laundry to contact with water in a larger space and to be washed, and also facilitating the laundry to rapidly approach the tub wall due to the guidance of the first water blocking area when the water is thrown, the water throwing speed is improved. Correspondingly, the assembling groove 211 is arranged in the vertical direction, and the distance between the two groove walls is gradually increased from bottom to top, so that the matching with the water disturbing ribs 51 is ensured, because the distance between the two groove walls at the notch of the assembling groove 211 is the largest, and the distance between the two rib side surfaces 512 of the water disturbing ribs 51 at the top surface 511 is the smallest, so that the water disturbing ribs 51 can be conveniently clamped in the assembling groove 211, and the connecting effect of the small barrel body 210 and the large barrel wave wheel 50 is ensured.

In an embodiment of the present application, the distance between the two rib side surfaces 512 of the water-disturbing rib 51 gradually increases from the rotation axis 412 to a direction away from the rotation axis 412. In the present embodiment, the washing tub structure 1000 is defined to have a horizontal direction perpendicular to the rotation axis 412, and in a radial direction of the tub 50, the distance between the two rib side surfaces 512 of the water-disturbing rib 51 gradually increases from inside (at the center of the rotation axis 412) to outside (at the tub wall of the tub 10), it can be understood that the two rib side surfaces 512 of the water-disturbing rib 51 are arranged in a substantially tapered shape in the horizontal plane, so that the contact area between the water-disturbing rib 51 and the assembling groove 211 can be increased, thereby improving the connection effect between the tub 210 and the tub 50, and when the tub 50 rotates to form a swirling flow, water can be easily guided to the middle portion of the tub 10 or a portion close to the tub wall, thereby allowing the laundry to contact with water in a larger space and thus be washed, and when the water is swirled, the laundry can be easily brought close to the tub wall due to the guidance of the first water blocking area, the water throwing speed is improved. Correspondingly, the assembling groove 211 should be in a radial direction, and the distance between the two groove walls is gradually increased from inside to outside, so as to ensure the cooperation with the water disturbing ribs 51, and thus, the connection effect of the keg body 210 and the large tub impeller 50 can be ensured.

Referring to fig. 25, in an embodiment of the present application, a distance between the second water disturbing area 5112 and the washing surface 52 is gradually decreased from the rotation axis 412 to a direction away from the rotation axis 412. It should be noted that the distance between the second water disturbing area 5112 and the washing surface 52 is the height of the second water disturbing area 5112 in the up-down direction, and referring to the linear velocity formula, the distance between the second water disturbing area 5112 and the rotation axis 412 is relatively long, therefore, the linear velocity of a portion of the second water disturbing area 5112 is relatively high, and the relatively high linear velocity can be achieved when the tub pulsator 50 rotates, the flow blocking ribs drive more water, but referring to the model of the vortex, the water quantity of the vortex in the middle of the vortex is small, the amount of water is large at the edge of the vortex, the height of the second water disturbing area 5112 is gradually reduced from the inside (at the axis 412 of the rotating shaft) to the outside (at the wall of the barrel body 10), the water retaining ribs can be smaller at places with high linear speed and larger at places with low linear speed, thereby when guaranteeing that water disturbance rib 51 rotates at vat impeller 50, the vortex that forms radially water yield distribution is even to guarantee clean effect.

Referring to fig. 12 and 24, in an embodiment of the present application, both the first water disturbing area 5111 and the second water disturbing area 5112 are arc surfaces; because the non-smooth top surface 511 is easy to form a higher water surface in the barrel body 10 when the barrel impeller 50 rotates, the cleaning effect caused by the lower water surface in some places in the barrel body 10 is reduced, when the first water disturbing area 5111 and the second water disturbing area 5112 are in smooth transition (arc surface arrangement), a smooth water surface can be formed when the barrel impeller 50 rotates, which is beneficial to uniformly washing the clothes in the barrel body 10, and the cleaning effect is good.

In one embodiment of the present application, the top surface 511 is disposed in an S-shape in a longitudinal section along an axis. The S-shaped arrangement can further ensure that when the big barrel impeller 50 rotates, the turbulence ribs stir water, and the formed rotational flow water volume is uniformly distributed in the radial direction, thereby ensuring the cleaning effect.

The quantity of water disturbance ribs 51 is less, and when vat wave wheel 50 rotated, the better water disturbance effect could only be realized to the rotational speed that needs faster to, the less contact area who disturbs water ribs 51 of quantity can reduce with assembly tray 211, reduces keg barrel body 210 and vat wave wheel 50's cooperation. When the number of the water disturbance ribs 51 is large, correspondingly, the bottom wall 213 of the keg body 210 to be matched is correspondingly provided with a corresponding number of assembling grooves 211, so that the strength of the bottom wall 213 of the keg body 210 is easily weakened, and the use is inconvenient. It can be understood that when the number of the water disturbance ribs 51 is one of four, five, six, seven and eight, on one hand, a good water disturbance effect can be ensured, and on the other hand, a good assembly effect of the large tub impeller 50 and the small tub body 210 can be ensured.

Referring to fig. 6, in an embodiment of the present application, the distance s1 from the end of the first water disturbing area 5111 adjacent to the rotation axis 412 is 39-43 mm, the distance s2 from the rotation axis 412 at the junction of the first water disturbing area 5111 and the second water disturbing area 5112 is 125-135 mm, the distance s3 from the rotation axis 412 at the end of the second water disturbing area 5112 away from the rotation axis 412 is 173-183 mm, that is, the width s4 of the first water disturbing area 5111 in the radial direction is 82-94 mm, and the width s5 of the second water disturbing area 5112 in the radial direction is 38-58 mm, so that a larger distance in the radial direction can be ensured to form a abdicating space, and the installation of the keg body 210 is facilitated.
