Specifically, as shown in fig. 1 and 2, the drum type washing and drying all-in-one machine of the present invention comprises a box body 1 and a drum assembly arranged in the box body 1, wherein the drum assembly comprises an inner drum 2, an outer drum 3 and a window gasket 4, the inner drum 2 is rotatably arranged in the outer drum 3, the window gasket 4 connects an opening of the outer drum 3 with a clothes input opening of the box body 1, the inner drum 2 can be directly driven to rotate by a direct drive motor, and the inner drum 2 can be further driven to rotate by a belt driven by the motor. The outer tub 3 serves to contain washing water, the inner tub 2 serves to turn laundry, and the window gasket 4 ensures sealing between the outer tub 3 and the cabinet 1. The barrel assembly is communicated with a drying air duct 5, a fan 10 is arranged in the drying air duct 5, preferably, an outlet of the drying air duct 5 is communicated with the window pad 4, an inlet of the drying air duct 5 is communicated with the outer barrel 3, and preferably, the air outlet pipeline 8 is communicated with the top of the outer barrel 3. In a more preferable case, an outlet of the drying duct 5 communicates with a top of the window mat 4, an inlet of the drying duct 5 communicates with a rear portion of the tub 3, and when the drying process is performed, the air in the tub 3 enters into the drying duct 5 from the inlet of the drying duct 5 at the rear portion of the tub 3, and the air in the drying duct 5 enters into the tub 3 from the window mat 4 via the outlet of the drying duct 5, so as to perform internal circulation drying of the laundry in the tub 2. A dehumidifying and heating device (not shown in the figure) is further arranged in the drying air duct 5, the dehumidifying and heating device can be a heat pump device, the heat pump device comprises an evaporator, a condenser and a compressor which are sequentially connected and form a refrigerant circulation loop, the evaporator and the condenser are both arranged in the drying air duct 5, the evaporator is located on the upstream side of the condenser (the relative position relationship between the evaporator and the condenser is described relative to the air flowing direction in the drying air duct 5 in the drying process), the evaporator is used for dehumidifying air, and the condenser is used for heating air. The dehumidifying and heating device can also be a combination of a condensing fin and an electric heating pipe, the condensing fin and the electric heating pipe are both arranged in the drying air duct 5, and the condensing fin is arranged at the upstream side of the electric heating pipe (the relative position relationship between the condensing fin and the electric heating pipe is described relative to the air flowing direction in the drying air duct 5 in the drying process), the condensing fin dehumidifies the air, and the electric heating pipe heats the air. Certainly, the dehumidifying and heating device can also be a semiconductor device, the semiconductor device comprises a cold end and a hot end, the semiconductor device is arranged in the drying air duct 5, the cold end dehumidifies the air, and the hot end heats the air. It should be noted that, in the above, the inlet and the outlet of the drying air duct 5 are both described with respect to the air flowing direction in the drying air duct 5 during the drying process, that is, when the drum-type washing and drying integrated machine executes the drying program, the air in the outer tub 3 is sucked into the drying air duct 5 from the inlet of the drying air duct 5 under the action of the fan 10, and the wet and cold air becomes dry and high temperature air after being dehumidified and heated by the dehumidifying and heating device, and then is sent back to the window mat 4 and the outer tub 3 through the outlet of the drying air duct 5, so as to circulate and reciprocate.

It should be noted that, the program of the all-in-one drum washer-dryer includes a washing program and a drying program, the washing program and the drying program may be executed sequentially, or only the washing program (i.e. only washing but not drying), or only the drying program (i.e. only drying but not washing), the conventional washing program includes a washing process, a rinsing process, a dewatering process and a draining process, in some all-in-one drum washer-dryer, the washing program may omit the dewatering process, and such adjustment or change of the conventional washing program of the all-in-one drum washer-dryer does not constitute a limitation of the present invention, and should be limited within the protection scope of the present invention, wherein, a large amount of foam may be generated in the washing process due to the existence of detergent/washing powder, and after the draining process is finished, residual water may exist on the inner surface of the outer tub 3 and the inner surface of the window mat 4.

It should be noted that when the drum-type washing and drying machine executes the ventilation program, the valve structure closing the portion of the drying air duct 5 located at the upstream side of the valve structure means that under the action of the fan 10, the outside air can enter the downstream side of the drying air duct 5 located at the valve structure and then enter the drum assembly via the outlet of the drying air duct 5, and the air in the drum assembly can only be discharged to the outside through the air outlet pipeline 8 because the valve structure closes the portion of the drying air duct 5 located at the upstream side of the valve structure, so that the drum assembly can be air-dried by the outside air, and the external circulation ventilation operation can be realized. When the drying program is executed by the washing and drying drum, the valve structure opening the portion of the drying air duct 5 located at the upstream side of the valve structure means that the air in the drum assembly can enter the drying air duct 5 located at the upstream side of the valve structure under the action of the fan 10, and then enter the drum assembly again via the downstream side of the drying air duct 5 located at the valve structure and the outlet of the drying air duct 5 in sequence, and the air in the drum assembly can circulate and flow back and forth in the drying air duct 5 and the drum assembly due to the valve structure disconnecting the drying air duct 5 from the outside, so that the clothes can be dried, and the internal circulation drying operation can be realized. In a preferred case, an on-off valve (e.g. an electromagnetic valve) may be disposed in the air outlet pipeline 8, and when the drum-type washing and drying machine executes the drying procedure, the on-off valve blocks the air outlet pipeline 8 from the outside, so as to prevent the drying gas from flowing out to the outside locally, thereby causing heat loss.
