The lower side of the extension portion 123 is provided with a slot 1232 matched with the protrusion 1412, and the rear cover 120 is connected with the upper cover 141 by inserting the protrusion 1412 into the slot 1232 and then using a fastener.

[0061] Specifically, the extension 123 and the upper cover 141 are buckled to each other through the cooperation of the slot 1232 of the extension 123 and the protrusion 1412 at the upper cover 141, and the extension 123 and the upper cover 141 are connected to each other by using the fastener, so that the rear cover 120 and the base 140 are tightly connected, and the sealing between the first air duct 1231 and the second air duct 1411 is ensured.

[0062] Specifically, as shown in Figure 10 the clothes processing device 100 of the embodiment can further include a condenser 150 and an evaporator 160, the condenser 150 and the evaporator 160 are arranged in the base 140, the air of the drum 110 flows into the base 140 through the first air duct 1231 and the second air duct 1411 from the rear side of the drum 110, and then enters the drum 110 from the front side of the drum 110 after passing through the evaporator 160 and the condenser 150.

[0063] Specifically, the drum 110 of the embodiment discharges air from the rear side, and the air enters the base 140 through the first air duct 1231 and the second air duct 1411, and then enters the drum 110 from the front side of the drum 110 after passing through the evaporator 160 and the condenser 150 in the base 140 to dry the clothes in the drum 110. The air enters from the front side and discharges from the rear side, which avoids heat loss of the air due to rotation of the drum 110 when the air enters from the rear side, and improves the utilization rate of heat.

[0064] As a specific embodiment of the utility model, Figure 10 and Figure 11 the clothes processing device 100 of the embodiment can further include a driving member 170 and a driving motor 180. The driving member 170 is located in the second air duct 1411 and rotates to push the air inside to flow in a controlled manner. The driving motor 180 can include a first output shaft 181 connected to the driving member 170 to drive the driving member 170 to rotate. The driving motor 180 can also include a second output shaft 182 driving the drum 110 to rotate through a belt 190.

[0065] Specifically, the driving motor 180 of the embodiment can drive the driving member 170 to rotate and make the air in the air duct and the drum 110 flow, and can also drive the drum 110 to rotate, which avoids the need for separate driving motors 180 to drive the drum 110 and the driving member 170 to rotate, and reduces the occupied space.
