Currently, most of the full-automatic washing machines on the market adopt a sleeve type structure of a dewatering barrel sleeved with a water storage barrel (washing barrel), and generally, the full-automatic washing machine consists of an outer barrel 1, an inner barrel 2 and a pulsator 3 shown in fig. 1, wherein the inner barrel comprises an inner barrel bottom 21, the pulsator 3 is rotatably arranged on the inner barrel bottom 21, and because the inner barrel 2 and the pulsator 3 move during washing and dewatering of the washing machine, gaps exist between the outer barrel 1 and the inner barrel 2 and between the pulsator 3 and the inner barrel bottom 21. Because the inner barrel 2 is provided with holes, dirty water for washing clothes can enter a gap between the outer barrel 1 and the inner barrel 2, and the long-term accumulation can cause the problem of dirt accumulation and scale accumulation of the washing machine, thereby causing secondary pollution to the clothes. The prior invention designs a washing machine for cleaning an interlayer between an outer tub 1 and an inner tub 2, for example, a sleeve tub is provided in chinese patent 200520050932.3, which comprises a fixed tub (water storage tub) and a rolling tub (dewatering tub), wherein a plurality of sheet-shaped cleaners are arranged between double tub walls of the fixed tub and the rolling tub, the cleaners generally adopt polygonal rubber sheets, and the cleaners collide with and clean dirt on the double tub walls under the driving of water flow. The present invention also designs a washing machine with a hole-free inner tub, because water exists only in the inner tub 2, the problem of dirt accumulation caused by dirty water for washing clothes entering a gap between the outer tub 1 and the inner tub 2 can be solved.
Although the arrangement of a plurality of cleaners between the tub walls of the outer tub 1 and the inner tub 2 and the arrangement of the inner tub 2 as a hole-free inner tub can solve the problem of dirt between the outer tub 1 and the inner tub 2, the gap between the pulsator 3 and the inner tub bottom 21 has a long time to be able to collect dirt due to the inability of the laundry to be in direct contact.

The laundry treating apparatus of the embodiment of the present invention is explained by taking a washing machine as an example, but is not limited to the washing machine, and may be a washing and drying integrated machine and other laundry treating apparatuses having similar structures. In this embodiment, since the inner tub 2 and the pulsator 3 move during washing and dewatering of the washing machine, gaps exist between the outer tub 1 and the inner tub 2 and between the pulsator 3 and the inner tub bottom 21, and in order to clean the gap between the pulsator 3 and the inner tub bottom 21, the cleaning device 5 between the inner tub bottom 21 and the pulsator 3 can solve the problem of dirt and scale between the inner tub bottom 21 and the pulsator 3 by providing the cleaning device 5. The cleaning device 5 is suitable for cleaning the perforated inner barrel and the pulsator 3, and is also suitable for cleaning the non-perforated inner barrel and the pulsator 3, and has good cleaning effect and wide applicable machine types.
The first embodiment is as follows: as shown in fig. 2 to 3, the laundry treating apparatus includes a rotating shaft 4 passing through the inner tub bottom 21, the pulsator 3 is fixedly connected to the rotating shaft 4, and the cleaning device 5 is rotatably provided on the rotating shaft 4. Because the rotating shaft 4 rotates in the washing or dehydrating process of the washing machine, the cleaning device 5 is arranged on the rotating shaft 4, the cleaning device 5 rotates under the driving of the rotating shaft 4 to clean the space between the pulsator 3 and the inner barrel bottom 21, and dirt cleaned by the cleaning device 5 flows out along with water flow in the draining process.
Further, as shown in fig. 3 to 4, the cleaning device 5 includes a connection part 51 and a cleaning part 52 connected to the connection part 51, the connection part 51 is provided on the rotation shaft 4, and the cleaning part 52 rotates around the rotation shaft 4 through the connection part 51 during the rotation of the rotation shaft 4; preferably, the connecting member 51 is a collar 511 sleeved on the rotating shaft 4, and the collar 511 is sleeved on the rotating shaft 4 without changing the structure of the rotating shaft 4, so that the invention has good adaptability and low design cost. The connecting part 51 and the rotating shaft 4 can be fixedly connected or movably connected. If the sleeve ring 511 is fixedly connected, the size of the sleeve ring 511 is equal to that of the rotating shaft 4, and when washing or dewatering is performed, the rotating shaft 4 rotates to drive the sleeve ring 511 to rotate, and the sleeve ring 511 drives the cleaning component 52 to rotate, so that cleaning is performed between the inner barrel bottom 21 and the pulsator 3; in order to achieve a more comprehensive cleaning effect, the collar 511 and the rotating shaft 4 are movably connected, that is, the dimension of the collar 511 is set to be larger than the dimension of the rotating shaft 4, and in the washing and dehydrating process of the washing machine, the cleaning device 5 moves in the radial, axial and circumferential directions of the rotating shaft 4 under the driving of the water flow and the rotating shaft 4, so that the comprehensive cleaning of the inner tub bottom 21 and the impeller 3 is realized.

During washing, the pulsator 3 or the inner tub 2 of the washing machine rotates, and the cleaning member 521 can rotate under the driving of water flow brought by the movement of the pulsator 3 or the inner tub 2 of the washing machine. While rotating, the cleaning member 521 continuously rubs, collides, and washes the pulsator 3 near the inner surface of the inner tub bottom 21 and the inner surface of the inner tub bottom 21 near the pulsator 3, thereby preventing dirt from adhering between the pulsator 3 and the inner tub 2 and maintaining the cleanliness between the pulsator 3 and the inner tub 2. The cleaning member 521 may have a rectangular parallelepiped shape or a cylindrical shape, and the cleaning member 521 is preferably formed in a rectangular parallelepiped shape in order to increase the contact area between the cleaning member 521 and the pulsator 3 or the inner tub bottom 21.

The width of the cleaning member 521 is smaller than the gap between the inner tub bottom 21 and the pulsator 3, the gap between the cleaning member 521 and the pulsator 3, and the gap between the cleaning member 521 and the inner tub bottom 21 are preferably 0-5mm, more preferably 0.5-2mm, and the preferred value of the gap between the radial direction and the inner tub bottom 21 is 0-5mm, more preferably 0.5-2mm, so that not only can the contact between the cleaning member 521 and the pulsator 3 and the inner tub bottom 21 be ensured to frictionally clean the inner tub bottom 21 and the pulsator 3, but also a certain movable space can be provided to enable the cleaning member 521 to collide with the inner tub bottom 21 and the pulsator 3 when moving axially along the rotation shaft 4, thereby avoiding the attachment of dirt.
The second embodiment is as follows: as shown in fig. 4, in this embodiment, in order to increase the cleaning capability of the cleaning member 521, an auxiliary cleaning structure is provided on the cleaning member 521, where 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 interferes with a certain position, which results in that other parts cannot be cleaned. The auxiliary cleaning structure is provided on at least one side of the cleaning member 521; the auxiliary cleaning structure is a brush uniformly distributed on the cleaning member 521, or a protrusion structure 5211 uniformly spaced on the cleaning member 521, and it is preferable that the protrusion structure 5211 include a dot-shaped protrusion and/or a bar-shaped protrusion in order to increase the cleaning effect.
