Preferably, as shown in Figures 7 and 9, the drying system of this embodiment further includes a first electronically controlled valve 91 installed on the air inlet pipeline 6, and the first electrically controlled valve 91 is used to control the air inlet pipeline 6 on-off status.

Wherein, the first electric control valve 91 is electrically connected with the controller of the washer-dryer, and the controller can control the first electric control valve 91 to turn the air inlet pipe 6 If it is disconnected, the drying air passage 4 is prohibited from communicating with the outside of the box body 1 through the air inlet pipeline 6, so as to avoid affecting the drying efficiency of the clothes due to the entry of cold air.

After the clothes are dried, the controller controls the first electric control valve 91 to connect the air inlet pipeline 6, so that the air inlet pipeline 6 connects the drying air duct 4 with the outside of the box body 1, so that the box body The cold air outside the body 1 is introduced.

Preferably, as shown in Figures 7 and 8, the drying system of this embodiment further includes a second electronically controlled valve 92 installed on the air outlet pipeline 7, and the second electronically controlled valve 92 is used to control the air outlet pipeline 7 on-off status.

Wherein, the second electric control valve 92 is electrically connected with the controller of the washer-dryer, and the controller can control the second electric control valve 92 to turn the air outlet pipeline 7 If it is disconnected, the drying air passage 4 is prohibited from communicating with the outside of the box body 1 through the air outlet pipeline 7, so as to avoid affecting the drying efficiency of the clothes due to the loss of hot air.

After the clothes are dried, the controller controls the second electric control valve 92 to connect the air inlet pipeline 6, so that the air outlet pipeline 7 communicates the drying air duct 4 with the outside of the box body 1, so that the box body The hot air inside the body 1 is exhausted.
