The drum 2 is an inner drum that can rotate and receive laundry. In order not to influence the rotation of a cylinder 2 and wash clothes, the inner wall of the cylinder 2 cannot be provided with a main air inlet and a shunt air inlet 3, the main air inlet 4 and the shunt air inlet 3 are positioned on a door seal assembly 21, and air can be supplied into the cylinder 2 from different positions in multiple directions.
When the drying air duct of this embodiment is used for washing and drying the all-in-one, set up main air intake 4 and reposition of redundant personnel air intake 3 on door seals subassembly 21, can realize multi-direction air supply to a section of thick bamboo 2 in drying earlier stage. In the later stage of drying, the main air inlet 4 is reduced or the main air inlet 4 is closed, when the amount of clothes in the drum 2 is higher than that of the shunting air inlet 3, as shown in fig. 9, the direction of arrows in the drawing indicates the direction of air flow, part of hot wind energy sent out by the shunting air inlet 3 blows to the clothes 6 at the upper part of the shunting air inlet 3, and part of hot wind energy blows to the clothes 6 at the lower part of the shunting air inlet 3, so that the clothes 6 at the bottom of the drum 2 can exchange heat with the hot wind, the drying efficiency is improved, the rotation time required by the drum for drying the clothes is shortened, and the generation of clothes burrs can be reduced.

Example two
The door seal assembly 21 is located outside the drum 2, and since the washing and drying machine needs to wash clothes, the main air supply outlet and the split air supply outlet cannot be located on the side wall of the drum. In order to make the air flowing out from the branch air inlet 3 blow into the barrel as much as possible, referring to fig. 6 and 7, the door seal assembly 21 of the present embodiment is further provided with an air guiding structure, which is located on the side of the branch air inlet 3 away from the barrel and can reflect part of the air flow blown out from the corresponding branch air inlet 3 into the barrel 2.

The drying air duct of this embodiment, in drying earlier stage, opens main air intake 4, and hot-blast from last down blows to the clothing, and a section of thick bamboo 2 drives the clothing rotation according to certain rotational speed. In the later stage of drying, the rotating speed of the drum is reduced and the drum rotates according to the preset rotating speed ratio, the main air inlet 4 is closed, and hot air flows to the shunt air inlet 3 through the delivery pipe and is blown to the inner drum through the shunt air inlet 3. Referring to fig. 9, when the laundry in the drum exceeds the height of the branch air inlet 3, a part of the air blown from the branch air inlet 3 blows toward the laundry at the upper part of the branch air inlet 3, and a part of the air blows toward the laundry at the lower part of the branch air inlet 3, even if the laundry is accumulated at the bottom of the drum 2, the laundry can contact with the hot air, and the drying efficiency is improved.
