After the washing step of the washing machine is finished, the driving piece 4 can discharge generated sewage to the outside of the washing machine through the water outlet pipeline 2 and the water discharge pipeline 6, so that sewage discharge is realized.
Optionally, referring to fig. 1 and 5, the water outlet pipeline 2 is provided with a third valve 21 electrically connected with the control module, and the control module can control the on-off between the water outlet pipeline 2 and the water discharge pipeline 6 through the third valve 21.

The sewage generated by washing is discharged out of the washing machine through the water outlet pipeline 2 and the water discharge pipeline 6. During the rinsing stage, after the tap water introduced into the inner barrel 100 of the washing machine reaches a preset water level, the control module controls the second valve 11 to disconnect the water inlet pipeline 1 from the tap water pipe, and to connect the water inlet pipeline 1 with the water outlet pipeline 2, and simultaneously controls the first valve 5 to connect the water outlet of the inner barrel 100 with the water inlet of the water purifying device 3, and the third valve 21 is closed to disconnect the water outlet pipeline 2 from the water outlet pipeline 6, so that purified rinsing water is introduced into the water inlet pipeline 1, and the recycling of the rinsing water is realized.
Alternatively, the water purifying apparatus 3 includes a filtering module for removing detergent and impurities in the rinse water, and a sterilizing module for removing bacteria in the rinse water. The filter module can be any structure capable of removing the detergent and impurities, and can adopt a chemical method or a biological method. In this embodiment, the filtration module illustratively includes hollow fiber membranes, which are shaped like fibers and have a self-supporting effect, and activated carbon. The hollow fiber membrane is a fiber yarn of a hollow inner cavity processed by taking polysulfone and dimethylacetamide as raw materials, and has the characteristic of selective permeation. The ultrafiltration membrane made of the hollow fiber membrane has the filtration precision within the range of 0.005-0.01 mu m, can effectively remove particles, colloid, bacteria, heat source and high molecular organic substances in water, and can realize the purification of rinsing water.
The detergent in the rinse water cannot be completely filtered by the hollow fiber membrane, so that the activated carbon can further adsorb the detergent in the rinse water, the content of the detergent in the rinse water is reduced, the cleanliness of the rinse water is improved, and the purified rinse water can meet the requirement of re-rinsing.
Bacteria may exist in the rinse water, so that bacteria in the rinse water can be effectively removed by arranging the sterilization module, and the use safety of the rinse water is ensured. Illustratively, the sterilization module may be a structure capable of emitting ultraviolet rays, and sterilization is achieved by ultraviolet ray irradiation.
Further, the filtering module and the sterilization module are detachably arranged on the water purifying device 3, so that periodic replacement is facilitated, and the rinsing water of the washing machine can be ensured to be normally recycled.
Optionally, referring to fig. 1 and 2, a first filter screen 7 is disposed at the water outlet of the inner cylinder 100, and a second filter screen 8 is disposed at the water outlet of the water purifying device 3. The first filter screen 7 is used for filtering impurities carried in sewage generated by washing (such as washed and shed fiber) and impurities carried in rinsing water, preventing sewage from blocking the water outlet pipeline 2 and rinsing water from blocking the water purifying device 3. The filtering precision of the second filter screen 8 is higher than that of the first filter screen 7, and the second filter screen 8 can further filter the purified rinsing water, so that the cleanliness of the rinsing water is improved.

If the laundry is dirty, the turbidity of the rinse water generated by the first rinsing is high, and the rinse water of the first rinsing is discharged out of the washing machine to protect the water purifying device 3.
Specifically, when the detection module detects that the turbidity of the rinse water in the inner cylinder 100 is greater than or equal to a preset value, the control module controls the first valve 5 to conduct the water outlet of the inner cylinder 100 and the water outlet pipeline 2, and disconnect the water outlet of the inner cylinder 100 from the water inlet of the water purifying device 3, and simultaneously controls the second valve 11 to disconnect the water outlet pipeline 2 from the water inlet pipeline 1, and the third valve 21 to open so that the water outlet pipeline 2 is communicated with the water drain pipeline 6, and the rinse water generated in the first rinsing is discharged out of the washing machine through the water outlet pipeline 2 and the water drain pipeline 6 under the action of the driving piece 4.
When the detection module detects that the turbidity of the rinse water in the inner barrel 100 is smaller than a preset value, the control module controls the second valve 11 to disconnect the water inlet pipeline 1 from the tap water pipe, and to connect the water inlet pipeline 1 with the water outlet pipeline 2, and simultaneously controls the first valve 5 to connect the water outlet of the inner barrel 100 with the water inlet of the water purifying device 3, and the third valve 21 is closed to disconnect the water outlet pipeline 2 from the water draining pipeline 6, so that the purified rinse water is led into the water inlet pipeline 1 through the water outlet pipeline 2 under the action of the driving piece 4, thereby realizing the recycling of the rinse water.
