The third concrete implementation mode: the protruding second bulge loop that forms of peripheral surface towards radial direction of center cylinder 6, the tip of second bulge loop court the joint ring that forms is extended at the one end or both ends of center cylinder 6 to the messenger the longitudinal section of second bulge loop is T type structure, set up on the adapting unit 51 with T type structure assorted C type groove, the joint ring stretches into in the C type groove, 3 rotation in-process of impeller cleaning component 52 is followed the second bulge loop is walked around. The length of the snap ring is smaller than the size of the C-shaped groove, so that the cleaning device 5 can move along the second convex ring in the axial direction, the radial direction and the circumferential direction of the central cylinder 6 without falling off.

Further, a spherical groove 5123/spherical protrusion 513 is disposed at one end of the connecting member 51 connected to the cleaning member 52, and a spherical protrusion 513/spherical groove 5123 is disposed at the corresponding end of the cleaning member 52 connected to the connecting member 51, so that during the rotation of the pulsator 3, the cleaning member 52 rotates and rotates in the spherical groove 5123 through the spherical protrusion 513, thereby achieving a better cleaning effect. Meanwhile, the central column 6 can be further provided with a plurality of cleaning devices 5, and the C-shaped grooves of the plurality of cleaning devices 5 are clamped on the second convex ring along the circumferential direction of the second convex ring.

The fifth concrete implementation mode:

the present embodiment is further defined in the cleaning member 52 on the basis of the first to fourth embodiments, as shown in fig. 7 to 10. The cleaning member 52 is a strip-shaped cleaning member 521, and the effect of the cleaning member 521 for cleaning between the inner tub 2 and the pulsator 3 is the same as the cleaning member 52 of the first embodiment of embodiment 1, and is not described herein again.

Further, in order to increase the cleaning capability of the cleaning member 521, an auxiliary cleaning structure is further disposed on the cleaning member 521, and the auxiliary cleaning structure can deform under the action of a force, so as to avoid the problem that the contact surface between the cleaning member 521 and the pulsator 3 or the inner tub bottom 21 is interfered at a certain position and the rest of the contact surface is inverted and cannot be cleaned. The auxiliary cleaning structure and the function are the same as those of the auxiliary cleaning structure of the second embodiment in embodiment 1, as shown in fig. 4, and are not repeated herein.

Further, the connecting member 51 is movably connected to the central column 6, at this time, the cleaning element 521 can move along the radial direction, the axial direction and the circumferential direction of the central column 6, the radial movement range of the cleaning element 521 is greater than or equal to the interval between two adjacent raised structures 5211, when the cleaning element 521 rotates along the circumferential direction of the central column 6, the movement tracks of the raised structures 5211 on the inner tub bottom 21 and/or the planar structure are staggered, so that the overall cleaning of the inner tub bottom 21 and the pulsator 3 is realized. Meanwhile, the axial movement range of the cleaning element 521 is greater than or equal to the distance between the impeller 3 and the inner barrel 2, so that the cleaning element 521 can contact with the impeller 3 and the inner barrel bottom 21 during the axial movement along the central column 6 to clean the inner barrel bottom 21 and the impeller 3, and dirt is prevented from being attached.

Although the present invention has been described with reference to a preferred embodiment, it should be understood that various changes, substitutions and alterations can be made herein without departing from the spirit and scope of the invention as defined by the appended claims.
