Specifically, a humidity sensor is provided in the drum 1, and the current humidity of the laundry in the drum 1 is detected by the humidity sensor;

to the unreasonable problem that leads to the clothing not in time and fully to stretch of control of auxiliary blower 25, this embodiment proposes that S2 includes:

s21, comparing the current humidity with a preset humidity;

s22, adjusting the rotating speed of the auxiliary fan 25 according to the comparison result of the current humidity and the preset humidity;

wherein, the lower the current humidity is, the higher the rotating speed of the auxiliary fan 25 is;

further, the preset humidity comprises a first preset humidity, a second preset humidity and a third preset humidity, and the first preset humidity, the second preset humidity and the third preset humidity are sequentially increased; s22 includes:

when the current humidity is greater than the second preset humidity and less than or equal to the third preset humidity, the auxiliary fan 25 is adjusted to rotate at the first rotation speed; under the action of two air flows, the clothes are gradually unfolded and loosened;

when the current humidity is greater than the first preset humidity and less than or equal to the second preset humidity, the auxiliary fan 25 is adjusted to rotate at a second rotation speed; the main drying air flow and the auxiliary drying air flow for high-temperature drying enter the roller 1 and act on clothes, so that on one hand, the clothes are fully unfolded, wrinkles of the clothes are avoided, on the other hand, the air flow is fully contacted with the clothes, and the drying efficiency is improved;

wherein the first rotational speed is less than the second rotational speed.

Aiming at the problem that the clothes shrink and deform due to long-time action of the drying air flow on the clothes, the embodiment provides that the control method further comprises the following steps:

comparing the current humidity with a first preset humidity;

when the current humidity is less than the first preset humidity, the control drum 1, the main blower 22, the auxiliary blower 25 and the compressor are all stopped.

In summary, by providing the main air duct and the auxiliary air duct 243 in the clothes dryer, compared with a single air duct clothes dryer, under the action of two air flows, the clothes which are easily turned into clusters in the drum 1 and are positioned below the left front (7 o' clock) of the drum 1 can be blown to the middle of the drum 1, so that the clothes are prevented from rolling into clusters in the drying process; the clothes can be dried in a better stretching state by opposite flushing of two air flows and adjusting the forward rotation and reverse rotation period of the roller 1, other parts of the clothes fiber which are bent can be stretched to bend, the bending position can be frequently changed, the bending amplitude is reduced, and the clothes fiber is dried in a state of bending after stretching for a while, so that the generation and fixation of clothes folds are reduced; atomized water generated by the atomizer 351 is mixed with the auxiliary drying air flow to generate a wet high-speed air flow; when the wetted high-speed air flow contacts with clothes, the generated wrinkles can be unfolded, so that the flatness and the drying uniformity of the clothes are improved, and a better nursing effect is achieved.
