As shown in fig. 2 to 4, the drum cleaning system of the washing machine of the present embodiment includes a shower 6. Wherein the spraying device 6 is provided on the outer wall of the inner tub 2 of the drum of the washing machine to spray water to a set area of the drum. Wherein, when the water inlet 611 of the spraying device 6 rotates to the water containing area of the drum along with the inner drum 2, water in the water containing area can enter the spraying device 6 from the water inlet 611.
With the above arrangement, in the drum cleaning system of the washing machine provided in this embodiment, when the water inlet of the spraying device 6 rotates to the water containing area in the process of rotating the inner drum 2, water in the water containing area can flow into the spraying device from the water inlet 611, and the spraying device 6 further sprays water to the set area of the drum, so as to achieve the purpose of cleaning the set area of the drum. Therefore, the washing machine roller cleaning system of the embodiment can spray and clean the roller without arranging an additional water pump and arranging a complex pipeline outside the roller, thereby simplifying the structure of the washing machine and reducing the cost of the washing machine.
Example 2
Preferably, compared with the previous embodiment, as shown in fig. 2 to 4, the spraying device 6 of the present embodiment sprays water from the spraying device 6 under the action of centrifugal force during the rotation of the inner drum 2.

The spray box 63 is provided with spray holes 631, and the spray box 63 communicates with the other end of the water pipe 61. A check valve 62 is provided at the communication between the shower box 63 and the water pipe 61 to prevent the water in the shower box 63 from flowing into the water pipe 61.
Preferably, the water inlet 611 of the spraying device 6 is arranged in a funnel-shaped structure, and the small diameter end of the water inlet 611 is connected with the water pipe 61.

Example 5
Preferably, the present embodiment provides a washing machine drum cleaning system, and the setting area of the present embodiment includes an outer tub bottom surface of the washing machine drum, compared to the above-described embodiments. Accordingly, as shown in fig. 2 to 4, the shower box 63 is for being disposed on the outer bottom of the inner tub 2 of the washing machine.

Specifically, as shown in fig. 4, the spraying holes 631 are distributed in a manner that the straight line of each row of spraying holes 631 intersects with the central axis of the inner cylinder 2 and is vertical), wherein the water outlet angles of the spraying holes 631 in the same row are different, and/or the water outlet angles of at least two rows of spraying holes 631 are different.

Specifically, the angles between the central axis of the spray holes and the central axis of the inner tube 2 in the direction extending in the same radial direction of the inner tube 2 are different (i.e., the inclination angles of the spray holes 631 in the radial direction are different). Preferably, the water outlet angles of the spray holes in two adjacent rows and even multiple rows are not the same (the fewer the number of spray holes in the radial direction, the more rows the different the adjacent spray hole angles are). The purpose of this design is: the number of the spraying holes 631 distributed in the radial direction of the first inner cylinder is not too large, the more the spraying holes 631 are, the closer the distance between the innermost spraying hole 631 and the central axis of the inner cylinder 2 is, the smaller the centrifugal force at the spraying hole 631 is, so that the smaller the water outlet pressure of the spraying hole 631 is, and the undesirable water blowing effect is possibly caused. Secondly, because the number of the spraying holes 631 in the radial direction of the inner cylinder is not large, if the water outlet angle of the spraying holes is not changed, the sprayed water flow can only clean a small annular area (because the inner cylinder 2 rotates) on the inner bottom surface of the rear cylinder, if the angles of the spraying holes in each row are reasonably arranged, a plurality of rows of spraying holes in radial arrangement can be utilized, and the water outlet can cover the inner bottom surface of the whole rear cylinder.
In addition, the washing machine drum cleaning system provided in the present embodiment is mainly used for cleaning the bottom surface of the outer drum (the bottom surface of the outer side of the rear drum) of the washing machine drum.
