Wherein, the middle-layer filter element 42 is set as a part for short-term cleaning, so as to be convenient for disassembly and assembly; the outer layer and the filter cotton are parts cleaned for a long time; the cambered surface in the middle of the middle layer filtering piece 42 is an appearance surface, the aperture in the middle is a vent hole, and the flock can enter the filter through the vent hole.

The fluff generated when the clothes in the inner drum of the clothes dryer are dried can flow along with the air flow and enter the filtering component 4 for filtering, and then the clean air flow flows to the heat exchanger component. That is, when the air current got into the heat exchanger subassembly from the urceolus, the flock of clothes can flow along with the air current, at first, get into inlayer and filter 41, part flock exists in inlayer and filter 41, remaining flock passes through inlayer and filters 41 and get into middle level along with the air current and filter 42, the ventilative cotton that filters of rethread, last through outer filter 43, most of flock of crossing all can be stayed the filter screen and filter on the cotton, only few part can be collected in heat exchanger subassembly department, this part flock can be cleared up through wind channel opening 11 can, consequently, can guarantee heat exchanger subassembly's cleanliness through adopting above structure, from this need not to be provided with the opening on wind channel base 2, need not to set up sealed door body group spare promptly, thereby the effectual quantity that has reduced opening and seam, the risk of gas leakage and losing temperature has been reduced. Therefore, by adopting the structure, the cleanliness of the heat exchanger assembly can be ensured, and the sealing effect of the clothes dryer can be effectively improved.

Further, in order to realize the function of washing clothes with steam, in the embodiment, the air duct base 2 is provided with the steam generator water tank 10, the steam generator is an additional function of the middle-high-end clothes dryer, and the steam generator water tank 10 is arranged on the air duct base 2, so that the universality of the air duct base 2 can be ensured: even if the dryer does not need the steam generator function, the steam generator water tank 10 disposed on the duct base 2 does not affect the installation of other necessary parts on the duct base 2.

The steam generator trough 10 is disposed on the air duct base 2, and in this embodiment, the steam generator trough 10 is disposed at the third accommodating cavity. Meanwhile, an overflow cavity 101 is also arranged, the overflow cavity 101 is communicated with the auxiliary water collecting cavity 65, and then the overflow cavity 101 is communicated with the water collecting cavity 5 at the second cavity 22; and the water level of the opening of the overflow cavity 101 is lower than that of the opening of the steam generator sink 10, when the water inflow of the steam generator sink 10 is excessive, the water enters the water collecting cavity 5 of the air duct base 2 through the overflow cavity 101 and can be drained away through the drainage pump. Meanwhile, a water sealing rib of the steam generator water tank 10 is arranged on the air duct upper cover 1 and is matched with the position of the steam generator water tank 10 on the air duct base 2; a water inlet nozzle of a steam generator water tank 10 and a buoy installation positioning structure are arranged at corresponding positions on the air duct upper cover 1 so as to meet the installation and use requirements of functions of the steam generator.

Further, the air duct upper cover 1 integrates the use function of the ion generator 12, wherein the ion generator 12 is arranged at the left rear part of the air duct upper cover 1 and is positioned in the air duct area at the rear part of the condenser, namely in the rear air duct area; the wind channel upper cover 1 has set up the 12 brush via holes of ion generator to and buckle, location muscle and screw post structure, with the installation and the operation requirement of satisfying the 12 functions of ion generator, this position is nearer with the condenser distance, and the anion effect efficiency that consequently produces is higher, thereby plays effectual bactericidal effect.

In summary, the periphery of the air duct base 2 is set to be a closed structure, that is, the air duct base 2 is a closed structure surrounded by the bottom plate, the first closing plate, the second closing plate, the third closing plate and the fourth closing plate, and the air duct upper cover 1 is tightly connected with the air duct base 2, that is, the first sealing joint surface 12 and the second sealing joint surface 21 on the air duct upper cover 1 are tightly connected, so that the air duct base 2 and the air duct upper cover 1 are tightly connected together. A filter assembly 4 is arranged between the front support 3 and the outer barrel, and the filter assembly 4 comprises an inner filter 41, a middle filter 42 and an outer filter 43 which are arranged in sequence from inside to outside; meanwhile, the air duct base 2 device comprises an air duct upper cover 1 and an air duct base 2, wherein an air duct opening 11 is formed in the air duct upper cover 1, one end of the heat exchanger assembly is arranged below the air duct opening 11, therefore, most of the fluff passing scraps can be left on the filter screen and the filter cotton, only a small part of the fluff passing scraps can be accumulated at the heat exchanger assembly, and the fluff of the part can be cleaned through the air duct opening 11, so that the cleanliness of the heat exchanger assembly can be ensured by adopting the structure, an opening is not required to be formed in the air duct base 2, namely, a sealing door body assembly is not required to be arranged, the quantity of the opening and the seam is effectively reduced, and the risks of air leakage and temperature loss are reduced. Therefore, by adopting the structure, the cleanliness of the heat exchanger assembly can be ensured, and the sealing effect of the clothes dryer can be effectively improved. The technical problem of poor sealing effect of the air duct base 2 device in the clothes dryer in the prior art is solved.
