After the drying process is finished or before the washing process is executed next time, the first telescopic sealing part 31 is controlled to move upwards to seal the drying air inlet 121. The first telescopic sealing part 31 can be driven by the drying driving mechanism to move upwards to block at the drying air inlet 121. Preferably, in this example, the first telescopic sealing portion 31 is sealed at the drying air inlet 121 under the action of the elastic mechanism, and the specific structure and the working principle of the drying sealing module 3 can be referred to in the first embodiment, which is not described herein again.

Further, a clothes obtaining unit for obtaining the clothes information of the clothes to be dried in the inner barrel is arranged in the washing and drying machine; the control unit controls the downward movement displacement of the first telescopic sealing part 31 according to the clothes information acquired by the clothes acquisition unit to adjust the opening size of the drying air communication port 211, so that the air intake amount is regulated and controlled, the function of a flow valve is achieved, and the clothes drying device is multifunctional.

For example, the washing and drying machine is provided with a device for obtaining weight information of clothes to be dried in the inner tub, and when the weight of the clothes to be dried is judged to be greater than a set weight, the drying air communication port 211 is controlled to be fully opened, so that sufficient drying air can be ensured to dry the clothes, and the drying effect of the clothes is improved.

When the weight of the clothes to be dried is judged to be less than the set value, the ratio of the opened part of the drying air communication port 211 to the whole drying air communication port 211 is controlled to be 1/3-1/2, so that the drying effect can be ensured, the energy consumption is reduced, and the resources are saved.

Further, a plurality of drying air inlets 121 are formed in the outer tub bottom wall 12 at intervals in the circumferential direction, the drying air inlets 121 are respectively communicated with the air outlet 201 of the drying module 2 through a plurality of drying channels, and the drying sealing modules 3 are respectively arranged on the plurality of drying channels.

When the drying program is executed, the control unit controls the drying sealing modules 3 in corresponding number and/or positions to open corresponding drying channels according to the clothes information acquired by the clothes acquisition unit.

Further, the laundry information includes weight information of the laundry and/or moisture content information of the laundry and/or material information of the laundry and/or category information of the laundry and/or position information of the laundry.

For example, in the embodiment, 5 drying air inlets 121 may be formed in the bottom wall 12 of the outer tub, and when it is detected that the moisture content or the weight value of the laundry to be dried in the inner tub is greater than a predetermined value, or when it is detected that the laundry is down jackets or other thick-type laundry, the number of the drying air inlets 121 opened is controlled to be 3-5, and the laundry is dried through the plurality of drying air inlets 121, so as to further ensure the drying effect of more laundry.

Or, a position detection unit for detecting the position information of the clothes is arranged in the washing and drying machine, and the drying air inlet 121 corresponding to the position of the clothes to be dried in the inner barrel is controlled to be opened according to the position distribution condition of the clothes to be dried in the inner barrel, so that the drying efficiency is improved.
