It should be noted that, the micro-plastics in the washing sewage are mainly polyester fibers and acrylic fiber fragments generated by friction between clothes and the washing drum 30 in the working process of the washing machine 100, and the first filter box 50 is arranged between the first drain pipe 41 and the second drain pipe 42, so that the micro-plastics in the sewage discharged by the washing machine 100 can be filtered out through the first filter box 50, thereby avoiding the deterioration of water pollution caused by direct discharge to the outside, and being beneficial to protecting water resources and ecological environment.

Wherein, the washing machine 100 further comprises a water inlet pipeline 60, the water inlet pipeline 60 comprises a first water inlet pipe 61 and a second water inlet pipe 62, the first water inlet pipe 61 is used for connecting an external water source, the second water inlet pipe 62 is communicated with the washing drum 30, and the first filter box 50 is further positioned between the first water inlet pipe 61 and the second water inlet pipe 62, so that the first filter box 50 can also filter micro-plastics in the external water source, thereby avoiding the micro-plastics in the external water source from entering the washing drum 30 in the washing process. It will be appreciated that the first filter box 50 of the present application can filter out not only the micro plastics in the wash water, but also the micro plastics in the external water source flowing into the wash bowl 30, so as to avoid secondary pollution caused by the micro plastics in the external water source.

Referring to fig. 2 in combination with fig. 3 and fig. 4, fig. 3 is a schematic structural view of the first filter cartridge in fig. 1, and fig. 4 is a schematic sectional view of fig. 3 along the direction A-A. Wherein, the first filter cartridge 50 includes a cartridge body 51 and a reverse osmosis membrane 52, the cartridge body 51 has a receiving chamber, the reverse osmosis membrane 52 is disposed in the receiving chamber, and the receiving chamber is divided into a first chamber 511 and a second chamber 512. The reverse osmosis membrane 52, also called RO membrane, is an artificial semipermeable membrane with certain characteristics and is made by simulating a biological semipermeable membrane, and is a core member of a reverse osmosis technology, and the principle of the reverse osmosis technology is that under the action of the osmotic pressure of a solution, other substances cannot permeate the semipermeable membrane and separate the substances from water. Because the membrane aperture of the reverse osmosis membrane 52 is smaller, the reverse osmosis membrane 52 can be facilitated to effectively remove microplastic in the laundry wastewater.

Wherein the first filter cartridge 50 comprises a water inlet 53, a first water outlet 54 and a second water outlet 55, the water inlet 53 is in communication with the first chamber 511, and the first water outlet 54 and the second water outlet 55 are in communication with the second chamber 512.
