With the progress of the living standard of people, equipment such as a washing and drying integrated machine and a clothes dryer with a clothes drying function gradually enter popular families. However, in the existing washing and drying integrated machine, clothes dryer and other devices, an air duct is generally connected to an outer cylinder, and a fan is arranged in the air duct to draw out wet hot air in the outer cylinder, so as to reduce humidity in the cylinder and dry clothes.

Washing machines are largely classified into pulsator type, and drum type washing machines. Generally, a washing machine removes stains from laundry by the action of water and detergent.

The pulsator type washing machine performs a washing operation by rotating a pulsator at the center of a washing tub left and right. The agitator type washing machine performs a washing operation using a frictional force between water current and laundry by rotating a rotary blade at the center of a washing tub in the left-right direction. The drum type washing machine performs a washing operation by beating laundry by rotating a drum.

A drum type washing machine generally includes a housing, an outer tub for containing washing water, a drum for containing laundry, and a motor and a shaft for rotating the drum.

As shown in fig. 1 to 5, in the present embodiment, a clothes treating apparatus is introduced, and the air duct 9 is disposed on the door body 7 of the clothes treating apparatus, so that the air duct 9 on the door body structure faces the drum opening 201, so as to guide external air flow into the drum 2 through the air duct 9, thereby achieving a technical effect of significantly improving air fluidity during the drying process of the clothes treating apparatus; meanwhile, the door body 7 is provided with the air guide duct 9, so that the door body 7 is utilized to guide air flow and improve the air inlet efficiency of the drum opening 201.

In this embodiment, the whole air duct 9 is flat, the closed end 702 of the air duct 9 is an arc surface 703 narrowing from the open end to the closed end 702, and the side wall of the air duct 9 near the door 7 is formed by an inclined surface inclined from the outer edge of the door 7 to the middle of the door 7 toward the direction near the open end.

Preferably, in this embodiment, the arc surface 703 of the air duct 9 is disposed coaxially with the drum 2, so as to effectively guide the airflow flowing into the drum 2 from the drum opening 201 along the axial direction of the drum 2.

Preferably, in this embodiment, a side wall of the air guide duct 9 close to the door 7 is formed by an inclined surface that gradually inclines from top to bottom toward the opening, so as to effectively guide the airflow flowing out of the air duct 5 to flow into the drum 2.

As shown in fig. 1, in the present embodiment, the drum door 10 is provided with an air permeable module 8 communicating both sides, and the air outlet 13 of the air guide duct 9 is disposed toward the air permeable module 8;

preferably, the ventilation module 8 may be any ventilation structure capable of achieving an air exchange effect between the inside and the outside of the drum 2 in the prior art, for example, the ventilation module 8 described in the above embodiment.

In this embodiment, the center of the roller door 10 is provided with the air permeable module 8 protruding toward the direction close to the door body 7, and the air permeable module 8 extends into the air guide duct 9 from the air outlet 13 and keeps a gap with the inner wall of the air guide duct 9, so as to ensure that a safety space is formed between the air permeable module 8 and the air guide duct 9 during the operation of the roller 2, and to effectively prevent the occurrence of the problems of mutual collision and the like between the air permeable module 8 and the air guide duct 9.

As shown in fig. 1, in the present embodiment, an outer cylinder 1 is arranged in a casing 18, a drum 2 is coaxially sleeved in the outer cylinder 1, a ring of annular window gasket 11 is connected between a cylinder opening 101 of the outer cylinder and the periphery of a clothes input opening of the casing 18, and an air guide channel 9 extends into a space surrounded by the annular window gasket 11 from a door body 7; the annular window pad 11 is provided with a joint 19 which is arranged opposite to the air inlet 12 of the air guide channel 9, and the joint 19 is communicated with the air outlet end of the air channel 5 of the clothes treatment device, so that the air flow flowing out of the air channel 5 can be guided into the space enclosed by the annular window pad 11 through the joint 19; the air outlet 13 of the air duct 9 is opened toward the drum opening 201, so that the air flow flowing into the air duct 9 from the air duct 5 is guided by the air duct 9 and flows into the drum 2. Preferably, in the present embodiment, the joint 19 is provided above the annular window mat 11 and extends in the radial direction of the door body 7.

Preferably, in this embodiment, when the door 7 is closed, the air inlet 12 of the air duct 9 is aligned with and pressed against the outlet of the joint 19. When the air flow flows into the air guide duct 9 from the air outlet end of the air duct 5, the air flow can completely flow in, and leakage between the air duct 5 and the air guide duct 9 is avoided.

Preferably, in this embodiment, the top end of the air inlet 12 of the air duct 9 is larger than the opening of the joint 19, and when the door body 7 is closed, the top end of the air inlet 12 of the air duct 9 covers the opening of the joint 19, so that the air flow transmission efficiency can be effectively improved.

Although the present invention has been described with reference to the preferred embodiments, it will be understood by those skilled in the art that various changes may be made and equivalents may be substituted for elements thereof without departing from the scope of the present invention.
