And no load is put in, the machine is started by pressing down the 'power supply', the 'intelligent air volume' key is pressed down, and the 'start' key is pressed down. At this time, the temperature sensor (NTC1) and the temperature sensor (NTC2) detect the exhaust capacity of the external exhaust pipe 11 of the dryer 1 through temperature change, and the feedback controller 16 PCB. The controller 16PCB drives the stepping motor to set the initial air volume F0. The clothes dryer 1 sets an air volume threshold FF, and if the set initial air volume F0< threshold FF, it indicates that the exhaust condition of the clothes dryer 1 is poor, and the user needs to check or clean the external exhaust pipe 11. After setting the initial air volume F0, the controller 16PCB stores the relevant settings and shuts down.
Specifically, after the new machine is installed or the external exhaust pipe 11 is periodically cleaned, the "intelligent air volume" setting flow chart is shown in fig. 3, and includes the following steps:
step S202: the instruction book reminds the user: after the new machine is installed or the external exhaust pipe 11 is periodically cleaned, the operation is as follows.

Step S212: the machine alarms to remind the user that the external exhaust pipe 11 is abnormal or the external exhaust pipe 11 needs to be cleaned.
Step S214: the user shuts down.
Step S216: the user checks or cleans the external exhaust pipe 11, and then returns to execute step S204.
Step S218: and the PCB stores relevant settings and is shut down.

And the temperature sensor (NTC1) and the temperature sensor (NTC2) judge whether the load volume in the inner cylinder 2 is larger according to the temperature value and the change. If the load volume is large, the controller 16PCB drives the stepping motor to increase the air volume F0+ dF, and the value of dF is determined by the controller 16PCB according to the temperature value and the change fed back by the temperature sensor (NTC1) and the temperature sensor (NTC 2). If the load volume is not large, the initial air volume F0 is kept constant.
2. And adjusting the air volume according to the user program.
The controller 16PCB determines if the user has selected a low temperature program for which the controller 16PCB sets the heater 12 to non-full power heating P1, P1 being less than the rated power P0 of the heater 12. Meanwhile, the controller 16PCB drives the stepping motor to set the matching air volume F1, F1 is smaller than the initial air volume F0, and the dryer 1 continues to work until the process is finished. For non-low temperature programs, the controller 16PCB sets the heater 12 full power heating P0.
3. And adjusting the air volume according to the load temperature.
The temperature sensor (NTC1) and the temperature sensor (NTC2) judge the temperature condition and the drying degree of the load in the inner drum 2 according to the temperature value and the change. During the drying process, if the temperatures of the temperature sensor (NTC1) and the temperature sensor (NTC2) do not reach the set thresholds T1 and T2, the drying process continues to keep the heater 12 heating P0 at full power. During the drying process, if the temperatures of the temperature sensor (NTC1) and the temperature sensor (NTC2) reach or exceed the set thresholds T1 and T2, the controller 16PCB sets the non-full power heating P1 of the heater 12, and the P1 is smaller than the rated power P0 of the heater 12. Meanwhile, the controller 16PCB drives the stepping motor to set the matching air volume F1, F1 is smaller than the initial air volume F0, and the dryer 1 continues to work until the process is finished.
Specifically, the flow chart of "intelligent air volume" used normally by the user, as shown in fig. 4, specifically includes the following steps:
step S302: the user uses the machine normally and presses the power supply of the machine to start the machine.
Step S304: selecting a program, pressing an intelligent air volume button on the panel and starting the clothes dryer 1.
Step S306: the PCB driving stepping motor sets an initial air volume F0 (reset from the last operation state).
Step S308: is the load volume too large judged from NTC1, NTC 2? If yes, go to step S310, otherwise go to step S312.
Step S310: the PCB drives the stepping motor to increase the air volume F0+ dF, and then step S314 is performed.
Step S312: the PCB holding stepping motor sets an initial air volume F0, and then performs step S314.
Step S314: is it determined whether the user selected the low temperature program? If yes, go to step S316, otherwise go to step S322.
Step S316: the PCB sets the heater 12 to non-full power heating P1(P1< P0), and then performs step S318.
Step S318: the PCB driving stepping motor sets a matching air volume F1(F1< F0), and then performs step S320.
Step S320: and continuing to work until the program is finished.
Step S322: the PCB sets the heater 12 to full power heating P0.
Step S324: determine that the NTC1 and NTC2 temperatures reach the set thresholds T1 and T2? If yes, go to step S316; if not, go to step S326.
Step S326: is it judged that the program end condition is reached? If so, the process ends, otherwise, the process returns to step S324.
Therefore, the dryer 1 produces the following advantageous effects: when the load volume is larger, the air exhaust volume can be increased; during the low-temperature program, less air quantity can be set to match with less power; in the later stage of drying, when the load temperature is higher, less air volume can be set to match with less power. Therefore, reasonable matching of air quantity and power is realized, drying efficiency is improved, and energy conservation and high efficiency are achieved.
Further, this example can be modified as follows: the temperature sensor (NTC1) and the temperature sensor (NTC2) can be used simultaneously or independently; and the air volume adjusting module is not limited to be mounted on the exhaust pipe 11.
The utility model discloses utilize temperature sensor and the adjustable module of air quantity, realize the reasonable matching of the amount of wind and power, improve drying efficiency, energy-conserving high-efficient.
