[0064] The first linkage 121 rotates in the washing cavity 21, so as to drive the second linkage 122 to slide the tray 11 in the washing cavity 21.

[0065] When the clothes on the tray 11 need to be taken out, the first linkage 121 and the second linkage 122 are unfolded, and drive the tray 11 to move to the vicinity of the dropping opening 22, so as to facilitate the user to take out the clothes; when the washing cavity 21 needs to wash the clothes, the first linkage 121 and the second linkage 122 are folded, and drive the tray 11 to move to the inner bottom wall of the washing cavity 21.

[0066] Preferably, the structure of the first linkage 121 and the structure of the second linkage 122 are both matched with the structure of the inner bottom wall of the washing cavity 21, so as to minimize the occupied space of the first linkage 121 and the second linkage 122 in the washing cavity 21 when they are folded, so that the clothes in the washing cavity 21 have a larger washing force, and the washing effect is improved; one end of the first linkage 121 is rotatably arranged on the inner side wall of the washing cavity 21 close to the washing tub.

[0067] Further, the transmission mechanism further comprises a first gear assembly, the first gear assembly comprising a first gear 131 and a second gear 132; the first gear 131 and the second gear 132 are rotatably arranged on the outer side wall of the washing cavity 21, and the first gear 131 is engaged with the second gear 132; the first gear 131 and the second gear 132 avoid occupying the space of the washing cavity 21, and ensure that the washing cavity 21 has sufficient space required for washing;

[0072] The third connecting rod 141 rotates in the washing cavity 21, so as to drive the fourth connecting rod 142 to slide the tray 11 in the washing cavity 21;

[0073] When the clothes on the tray 11 need to be taken out, the third connecting rod 141 and the fourth connecting rod 142 are unfolded, and drive the tray 11 to move to the vicinity of the feeding opening 22, so as to facilitate the user to take out the clothes; when the washing cavity 21 needs to wash the clothes, the third connecting rod 141 and the fourth connecting rod 142 are folded, and drive the tray 11 to move to the inner bottom wall of the washing cavity 21;

[0074] Preferably, the structure of the third connecting rod 141 and the structure of the fourth connecting rod 142 are both matched with the structure of the inner bottom wall of the washing cavity 21, so as to minimize the occupied space of the third connecting rod 141 and the fourth connecting rod 142 in the washing cavity 21, so that the clothes in the washing cavity 21 have a larger washing force, and the washing effect is improved; one end of the third connecting rod 141 is rotatably arranged on the inner side wall of the washing cavity 21 close to the washing drum.

[0075] In addition, the first connecting rod 121, the second connecting rod 122, the third connecting rod 141 and the fourth connecting rod 142 are staggered in the axial direction of the door body 2 when they are in the folded state; the structure of the tray 11 is matched with the structure of the inner bottom wall of the washing cavity 21, so as to reduce the occupied space of the tray 11 in the washing cavity 21.

[0076] Specifically, the first connecting rod assembly is arranged near the left side of the washing cavity 21, and the second connecting rod assembly is arranged near the right side of the washing cavity 21; the first connecting rod 121, the second connecting rod 122 and the tray 11 (the sliding block) constitute a crank slider mechanism; the third connecting rod 141, the fourth connecting rod 142 and the tray 11 (the sliding block) constitute another crank slider mechanism; when the first connecting rod 121 swings clockwise and the third connecting rod 141 swings counterclockwise, the tray 11 can slide upward in the washing cavity 21; when the first connecting rod 121 swings counterclockwise and the third connecting rod 141 swings clockwise, the tray 11 can slide downward in the washing cavity 21.

[0077] Further, the transmission mechanism further comprises a second gear assembly, the second gear assembly comprising a third gear 151 and a fourth gear 152; the third gear 151 and the fourth gear 152 are rotatably arranged on the outer side wall of the washing cavity 21, and the third gear 151 is engaged with the fourth gear 152; the third gear 151 and the fourth gear 152 avoid occupying the space of the washing cavity 21, so as to ensure that the washing cavity 21 has sufficient space required for washing.
