The controller determines the rotating speed of the fan and the output power of the heating rod 9 according to the current relative humidity, and correspondingly controls the fan and the heating rod 9 to work. The humidifying body 4 absorbs water in the water storage box 1 to the outside of the water storage box 1, and air flow generated above the water storage box 1 flows through the humidifying body 4 under the action of the fan, so that moisture in the humidifying body 4 is diffused to the environment. As the rotation speed of the fan increases, the flow rate of air flowing through the humidifying element 4 per unit time increases, and the diffusion of moisture in the humidifying element 4 increases. The heating rod 9 is positioned in the water storage box 1 and used for heating the water in the water storage box 1, so that the water in the water storage box 1 is directly diffused to the environment in the form of steam. The heating efficiency of the heating rod 9 can be adjusted by adjusting the output power of the heating rod 9, so that the evaporation rate of water in the water storage box 1 is adjusted to increase the dehumidification strength.

In the embodiment of the present invention, in step S200, controlling the rotation speed of the fan and the output power of the heating rod 9 according to the current relative humidity includes:
s201, acquiring the current temperature and the target relative humidity of the environment;
s202, determining humidity compensation to be carried out on the current relative humidity according to the current temperature and the target relative humidity;
s203, adjusting the rotating speed of the fan and the output power of the heating rod 9 according to the humidity compensation.
Specifically, the current temperature of the environment may be detected by a temperature sensor and the detection result may be sent to the controller. Of course, a temperature/humidity sensor may be used to detect the current temperature and the current relative humidity of the environment. The target relative humidity can be self-contained in the system or can be set manually by a user according to self needs. The controller compares the current relative humidity with the target relative humidity, and performs temperature compensation on the current relative humidity at the current temperature according to the difference between the current relative humidity and the target relative humidity. And determining the proper fan rotating speed and the output power of the heating rod 9 according to the temperature compensation, and correspondingly controlling the operation of the fan and the heating rod 9.
In the embodiment of the invention, the rotating speed of the fan and the output power of the heating rod 9 can be adjusted according to the set relative humidity interval, so that the adjusting steps are simplified. Specifically, in step S200, the controlling the rotation speed of the fan and the output power of the heating rod according to the current relative humidity specifically includes:
s204, if the current relative humidity is smaller than a first relative humidity threshold value, controlling the rotating speed of the fan to be a first rotating speed, and controlling the output power of the heating rod 9 to be a first output power;
s205, if the current relative humidity is not less than the first relative humidity threshold and less than the second relative humidity threshold, controlling the rotating speed of the fan to be a second rotating speed, and controlling the output power of the heating rod 9 to be a second output power;
s206, if the current relative humidity is not less than the second relative humidity threshold value, controlling the rotating speed of the fan to be a third rotating speed, and controlling the output power of the heating rod 9 to be a third output power;
wherein the third rotational speed is less than the first rotational speed and the second rotational speed, and the first output power is greater than the second output power and the third output power.
Specifically, the first relative humidity threshold and the second relative humidity threshold may be provided by the system itself, or may be set manually by the user according to the needs of the user. The first and second relative humidity thresholds divide the humidity into three humidity range intervals. In this embodiment, the first rotation speed, the second rotation speed, and the third rotation speed of the fan, and the first output power, the second output power, and the third output power of the heating rod 9 may be calculated according to the temperature compensation, or may be preset fixed values.
For example, the first relative humidity threshold is 20% and the second relative humidity threshold is 40%. If the former relative humidity is less than 20%, judging that the environment is dry at the moment, controlling and adjusting the rotating speed of the fan to be the maximum rotating speed, and adjusting the output power of the heating rod 9 to be the maximum output power, so as to adjust the humidifying strength to be the maximum; if the relative humidity is not less than 20% and less than 40%, and the environment is judged to be relatively dry, controlling the adjusting fan to operate at the maximum rotating speed or at a large rotating speed, wherein the output power of the heating rod 9 is 0, and then closing the heating rod 9; if the former relative humidity is not less than 40%, and the environment humidity is judged to be appropriate at this time, the rotating speed of the adjusting fan is controlled to operate at a lower rotating speed, and the heating rod 9 is closed.
Further, if the current relative humidity is within a preset standard relative humidity range, the rotating speed of the fan is controlled to be the lowest rotating speed, and the heating rod 9 is controlled to be closed. The standard relative humidity can be carried by the system, and can also be set manually by a user according to the requirement of the user. The system adjusts the rotating speed of the fan and the output power of the heating rod 9 in real time according to the current relative humidity until the current relative humidity reaches the standard relative humidity range. For example, the standard relative humidity range is a relative humidity of not less than 50%. When the current relative humidity reaches 50%, the fan is controlled to operate at the lowest rotating speed and the heating rod 9 is turned off, and at the moment, the humidifying device enters a dormant state.
Further, in the embodiment of the present invention, the three-way valve 6 is in communication with the water level sensor 10. Specifically, the controller is in communication with the three-way valve 6 and the water level sensor 10, respectively. When the water level sensor 10 detects that the water level in the water storage box 1 is higher than the set highest water level, the controller controls the solenoid valve core of the three-way valve 6 to move, the first water outlet 62 is closed, and the second water outlet 63 is opened, so that redundant water in the indoor unit drain pipe or the outdoor unit drain pipe is discharged to the outside, and the water in the water storage box 1 is prevented from overflowing.
