[0064] As shown in Figure 1 and Figure 3 When the clothes to be washed only comprise clothes with stains or comprise clothes with stains and clothes without stains, the first sub barrel 121 and the second sub barrel 122 are in the first state, the first sub barrel 121 and the second sub barrel 122 are arranged opposite to each other along the diameter direction of the main washing barrel 11, the first sub barrel 121 and the second sub barrel 122 are cooperated and surrounded to form a first sub washing area 131; a second sub washing area 132 is formed between the main washing barrel 11 and the sub washing barrel 11, the second sub washing area 132 is located below the first sub washing area 131, and the second sub washing area 132 is not communicated with the first sub washing area 131; the clothes with stains are placed in the first sub washing area 131, and the clothes without stains are placed in the second sub washing area 132; when the first sub barrel 121 and the second sub barrel 122 are synchronously rotated with the main washing barrel 11, the first sub washing area 131 can be used for washing the clothes with stains, and the second sub washing area 132 can be used for washing the clothes without stains; because the first sub washing area 131 and the second sub washing area 132 are not communicated, washing is complete and efficient, and secondary pollution is avoided.

[0065] As shown in Figure 2 and Figure 4As shown, when the laundry to be washed only includes the clothes without stains, the first sub-barrel 121 and the second sub-barrel 122 are in the second state, the first sub-barrel 121 and the second sub-barrel 122 are oppositely arranged along the axial direction of the main washing barrel 11 or the first sub-barrel 121 and the second sub-barrel 122 are sleeved together; the first sub-barrel 121 and the second sub-barrel 122 are both in communication with the main washing barrel 11, and the main washing barrel 11 is formed with a main washing area 14, and the laundry to be washed is placed in the main washing area 14, so that the main washing area 14 can wash the laundry to be washed.

[0066] In summary, the washing machine 1 has simple structure, various functions and wide application range; the first sub-barrel 121 and the second sub-barrel 122 can be in different states according to actual needs, the washing is complete and the washing time is shortened.

[0067] In view of the problem that the process of making the first sub-barrel 121 and the second sub-barrel 122 in the first state is complex, the embodiment provides that the side wall of the first sub-barrel 121 and the side wall of the second sub-barrel 122 are both in circular arc structure; specifically, the side wall of the first sub-barrel 121 and the side wall of the second sub-barrel 122 are both in semicircular structure, and the side wall of the first sub-barrel 121 and the side wall of the second sub-barrel 122 are both adapted to the side wall of the main washing barrel 11; one side of the side wall of the first sub-barrel 121 is open and the other side is closed, and one side of the side wall of the second sub-barrel 122 is open and the other side is closed; the first sub-barrel 121 is rotatably arranged in the main washing barrel 11, and the rotation axis of the first sub-barrel 121 is parallel to the axial direction of the main washing barrel 11; preferably, the rotation axis of the first sub-barrel 121 is collinear with the axis of the main washing barrel 11; the first sub-barrel 121 has a first position in the rotation direction thereof, and when the first sub-barrel 121 is in the first position, the first sub-barrel 121 is located on one side in the diameter direction of the main washing barrel 11 and on one side in the axial direction of the main washing barrel 11;
