In one embodiment of the invention, a self-cleaning system for a washing machine includes a self-cleaning device; the self-cleaning device is arranged on the inner drum 1 of the washing machine for cleaning a predetermined portion between the inner drum 1 and the outer drum 2 of the washing machine. By providing the self-cleaning device on the inner drum 1 of the washing machine, the cleaning medium of the self-cleaning device can form sputtering between predetermined portions between the inner drum 1 and the outer drum 2 of the washing machine along with the rotation of the inner drum 1 of the washing machine itself, thereby effectively cleaning residues between the inner drum 1 and the outer drum 2 of the washing machine.
As shown in fig. 1, in one embodiment, the rear of the inner drum 1 is connected with the rear of the outer drum 2 through a rotation shaft 3, and the front of the inner drum 1 and the front of the outer drum 2 have openings for putting in and taking out laundry. During operation of the washing machine, the outer drum 2 is stationary and the inner drum 1 rotates relative to the outer drum 2. The preset parts are the rear part 22 of the inner wall of the outer drum 2 of the washing machine and the rear part 11 of the outer wall of the inner drum 1 of the washing machine; in another embodiment, the predetermined portions are a middle front portion 22 of an inner wall of the outer drum 2 of the washing machine and a middle front portion 12 of an outer wall of the inner drum 1 of the washing machine. Of course, the predetermined portion is not limited to the above portion, and may be any combination of predetermined portions in the above embodiment. In a preferred embodiment, the predetermined portions are a rear portion 22 of the inner wall of the outer drum 2 and a rear portion 11 of the outer wall of the inner drum 1 of the washing machine, and a middle front portion 22 of the inner wall of the outer drum 2 and a middle front portion 12 of the outer wall of the inner drum 1 of the washing machine. In the preferred embodiment, all areas between the inner and outer drum of the washing machine can be cleaned by the rotation of the rotation shaft 3. The rear part herein refers to a side of the drum interior of the washing machine relatively far from the drum opening of the washing machine in the drum axis direction, and the middle front part refers to a side of the drum interior of the washing machine relatively close to the drum opening of the washing machine in the drum axis direction.

In this figure, the self-cleaning system comprises hollow pipes arranged in a tripod 4 and/or a lifting rib 5 on the drum 1 in the washing machine and spouts distributed on the hollow pipes. Therefore, by using the space in the tripod 4 and/or the lifting rib 5 on the inner drum 1 of the washing machine to arrange the hollow pipeline and arranging the nozzle on the hollow pipeline, the space of the inner drum 1 of the washing machine is effectively utilized; moreover, more importantly, high-pressure cleaning media, such as purified water, are introduced into the hollow pipeline, so that the high-pressure purified water sprayed out through the spray nozzles can directly wash the inner wall of the outer roller 2, and meanwhile, the high-pressure cleaning media, such as the high-pressure purified water, are sputtered to the outer wall of the inner roller 1 through the inner wall of the outer roller 2 to sputter wash the outer wall of the inner roller 1, so that residues among the rollers can be effectively cleaned.
In the embodiment shown in fig. 1, 3 and 4, the spout 71 of the hollow conduit 61 is located at the bottom surface of the outer wall of the inner drum 1, facing the bottom surface of the inner wall of the outer drum 2. In this way, when the high-pressure cleaning medium, such as high-pressure purified water, is sprayed from the above-mentioned spray nozzles, the high-pressure water impinges on the inner wall bottom surface of the outer drum 2, and at the same time, the rear portion of the inner wall of the outer drum 2, which is close to the inner wall bottom surface, is also flushed due to the sputtering effect, and at the same time, the sputtered high-pressure water is reflected to the outer wall bottom surface of the inner drum 1 and the portion of the outer wall bottom surface, which is close to the outer wall bottom surface, to flush. Therefore, the rear portion 22 of the inner wall of the outer drum 2 of the washing machine and the rear portion 11 of the outer wall of the inner drum 1 of the washing machine can be washed and cleaned by the high-pressure purified water sprayed from the nozzle 71 of the hollow pipe 61.

The self-cleaning system is detachable, can be selectively installed in the tripod 4 or the lifting rib 5, and can flexibly select the installation mode according to the cleaning requirement of the preset part of the actual situation.
In one embodiment, the first hollow pipe 61 is provided in at least one leg of the tripod 4 of the inner drum 1, and the second hollow pipe 62 is provided in at least one of the lifting ribs of the inner drum 1. During the self-cleaning process, the inner drum 1 rotates, so that the first hollow pipe 61 can be selectively installed on only one leg of the tripod 4, and the ideal cleaning can be realized through the rotation. Of course, it is possible to selectively install the first hollow conduits 61 in two legs or three legs, and as the number of installed first hollow conduits 61 increases, the cleaning effect increases. During self-cleaning, the inner drum 1 rotates, so that it is possible to install the second hollow pipe 62 in only one of the lifting ribs 5, and cleaning can be achieved by rotation. Of course, it is possible to selectively install the second hollow pipes 62 in two lifting ribs or three lifting ribs, and as the number of installing the second hollow pipes 62 increases, the cleaning effect increases.
