The drying device described in this embodiment can automatically control the dehumidifying air valve actuator 6, the first dehumidifying air valve actuator 8 and the second dehumidifying air valve actuator 10 through the controller to control the opening degree of the corresponding air valve, thereby realizing the air volume adjusting function. The dehumidifying air valve 5 and the dehumidifying air valve are controlled by the controller, so that the drying device can carry out self-circulation dehumidification, and normal drying and dehumidifying functions are realized; the moisture can be discharged, and the normal drying and moisture discharging functions can be realized; and the dehumidification can be simultaneously carried out, and the drying, the dehumidification and the dehumidification functions can be simultaneously realized.
In practical use, as shown in fig. 4, in the early stage of drying (for example, the second humidity value is greater than the third humidity value, and the third humidity value is greater than the first humidity value), the drying device according to this embodiment uses the dehumidification function by opening the first dehumidification air valve 7 and the second dehumidification air valve 11, and closes the dehumidification air valve 5, and correspondingly closes the dehumidification function. So that the humidity in the drying process can effectively reach the preset working condition through the dehumidifying system.

Specifically, when the second humidity value is greater than the first humidity value and the first humidity value is greater than the third humidity value, the dehumidification system and the dehumidification system of the drying device are controlled to be started simultaneously; or when the second humidity value is larger than the first humidity value and the first humidity value is larger than the third humidity value, the dehumidifying system of the drying device is controlled to be started firstly, and after the first humidity value is larger than the second humidity value, the dehumidifying system of the drying device is controlled to be started.
In the later stage of drying (for example, the first humidity value is greater than the second humidity value, and the second humidity value is greater than the third humidity value), as shown in fig. 5, by adjusting the opening of the 3 air valves, since the humidity of the external environment is much greater than the humidity in the drying room and the dehumidification function is not suitable for use, the dehumidification air valve 5 is opened, the dehumidification function is used, the first dehumidification air valve 7 and the second dehumidification air valve 11 are closed, and the dehumidification function is correspondingly closed. So that the humidity in the drying process can effectively reach the preset working condition through the dehumidification system.
As shown in fig. 4, when the dehumidifying system is in operation, on one hand, the first dehumidifying air valve 7 introduces return air in the drying room into the device under the action of the first dehumidifying air valve actuator 8, the return air passes through the heat exchanger 9 and is discharged into the external evaporator 12, and after being processed by the external evaporator 12, the return air is discharged out of the drying room through the external fan 13; on the other hand, the second moisture exhaust air valve 11 introduces fresh air outside the drying room into the device under the action of the second moisture exhaust air valve actuator 10, and the fresh air is sent into the drying room through the inner fan 1 after being subjected to temperature rise treatment by the heat exchanger 9 and the electric heating assembly 2, so that the drying and moisture exhaust functions are realized.
As shown in fig. 5, when the dehumidification system works, the dehumidification air valve 5 introduces return air in the drying room into the device under the action of the dehumidification air valve actuator 6, the return air passes through the dehumidification evaporator 4, then sequentially passes through the condenser 3 and the electric heating assembly 2 for treatment, and finally is sent into the drying room through the inner fan 1 to realize the drying and dehumidification functions.
