Specifically, the method for detecting and controlling the humidity in the air conditioner air duct and the method for detecting and controlling the humidity in the air conditioner air duct.
Specifically, for the method for detecting and controlling the humidity in the air duct of the air conditioner, referring to fig. 1, the method comprises the following steps:
Step S100, a first humidity value in an air duct of the air conditioner is obtained in real time in the power-on state and the power-off state of the air conditioner body.

And step 200, generating a first air duct dehumidification signal according to the obtained first humidity value.
Specifically, the first humidity value can represent the humidity condition in the air conditioner air duct, and whether the air conditioner air duct is in a wet state for a long time can be judged according to the first humidity value. For example, when the humidity value in the air conditioner air duct is in a higher value for a long time, the humidity value indicates that the air conditioner air duct is in a moist state for a long time, and the air conditioner indoor unit heat exchanger is judged to be easy to mildew and generate mildew spots after that, so that a first air duct dehumidification signal is generated.
And step S300, when at least one of an air conditioner body power-on signal, a starting signal and an operation signal is obtained, a first air duct dehumidification signal is sent to the air conditioner body.
Specifically, the embodiment detects whether the air duct of the air conditioner is in a wet state for a long time through the humidity detection device, and the humidity detection device comprises a humidity sensor, a first communication module and a first controller.
The air conditioner body of the air conditioner refers to integration of an air conditioner inner unit and an air conditioner outer unit, and can reduce or improve the temperature of a refrigerant through a compression system so as to cool or heat ambient air. Specifically, the air conditioner indoor unit is generally located indoors, and the air conditioner outdoor unit is located outdoors. However, for the mobile air conditioner, the evaporator and the condenser are both located indoors, at this time, the part where the evaporator is located when the air conditioner is refrigerating is the air conditioner indoor unit, and the part where the condenser is located when the air conditioner is refrigerating is the air conditioner outdoor unit, which also falls within the protection scope defined by the air conditioner body, the air conditioner indoor unit and the air conditioner outdoor unit in the embodiment.
In the embodiment, when the air conditioner body is powered off and powered on, the first air duct dehumidification signals are generated according to the obtained first humidity value. If the air conditioner body is in a power-off state when the first air duct dehumidification signal is generated, after the air conditioner body is electrified, an electrifying signal is sent to the humidity detection device, and after the first controller of the humidity detection device obtains the electrifying signal, the generated first air duct dehumidification signal is sent to the air conditioner body.

And step M200, generating a second air duct dehumidification signal according to the obtained second humidity value.
Specifically, the second humidity value can represent the humidity condition in the air conditioner external unit air duct, and whether the air conditioner external unit air duct is in a wet state for a long time can be judged according to the second humidity value. For example, when the humidity value in the air conditioner outdoor unit air duct is in a higher value for a long time, the air conditioner outdoor unit air duct is in a moist state for a long time, and the air conditioner outdoor unit heat exchanger is judged to be easy to mildew and generate mildew spots after that, so that a second air duct dehumidification signal is generated.
And step M300, when at least one of an air conditioner body power-on signal, a starting signal and an operation signal is obtained, a second air duct dehumidification signal is sent to the air conditioner body.
Similarly, in the embodiment, when the air conditioner body is powered off and powered on, the second air duct dehumidification signal is generated according to the obtained second humidity value. If the air conditioner body is in a power-off state during generation of the second air duct dehumidification signal, after the air conditioner body is electrified, the first controller of the humidity detection device obtains the electrified signal and then sends the generated second air duct dehumidification signal to the air conditioner body. And when the second air duct dehumidification signal is generated, if the air conditioner body is in a state that the power-on unit is not started, the air conditioner body sends power-on signals to the humidity detection device at intervals at the moment, or generates starting signals to the humidity detection device when the air conditioner body is started, and after the first controller of the humidity detection device obtains the power-on signals or the starting signals, the generated second air duct dehumidification signal is sent to the air conditioner body. And when the second air duct dehumidification signal is generated, if the air conditioner body is in a startup state, the air conditioner body sends an electrifying signal, a startup signal or an operation signal to the humidity detection device at intervals at the moment, or when the air conditioner body is closed and restarted, the startup signal is generated and sent to the humidity detection device, and when a first controller of the humidity detection device obtains at least one of the electrifying signal, the startup signal and the operation signal, the generated second air duct dehumidification signal is sent to the air conditioner body.
