In addition, the user cannot select the humidification mode before the air conditioner humidifies, and cannot focus on local area humidification according to the detection result of the human body, which leads to a large space for improving user satisfaction.

In addition, the humidification mode for the indoor is determined according to the selection of the user, different humidification requirements of the user are met, and the satisfaction of the user is improved. Figure 1 and Figure 2 as shown, comprising steps S1-S3:

[0064] S1: judging whether the indoor needs humidification;

[0065] S2: detecting water level data in the total water storage cavity storing the condensed water when it is determined that the indoor needs to be humidified;

[0066] S3: receiving a humidification mode selected by a user to perform a humidification operation when it is determined that the water level data is greater than a preset water level; the humidification mode includes a whole humidification mode and a local humidification mode.

[0069] In this embodiment, the preset water level is a minimum water level that is set in advance to ensure that humidification can be performed.

[0070] In this embodiment, the whole humidification mode is a mode of balanced humidification of the whole indoor.

[0071] In this embodiment, the local humidification mode is a mode of targeted and focused regional humidification by identifying the location of the human body.

[0072] The working principle and beneficial effects of the above technical solution are as follows: by judging whether the indoor needs to be humidified, the water level data in the total water storage cavity storing the condensed water is detected when it is determined that the indoor needs to be humidified, and the whole humidification mode or the local humidification mode operation is performed by receiving the humidification mode selected by the user when it is determined that the water level data is greater than the preset water level, which can effectively utilize the condensed water of the air conditioner to humidify the indoor, not only ensuring the humidification effect of the indoor, but also reusing the condensed water, reducing the use of external water source, and reducing the waste of water resources. And by providing user selection, the humidification mode of the indoor is determined according to the user selection, which meets the different humidification needs of the user and improves the satisfaction of the user.

[0078] comparing the detection humidity value with a preset humidity value;

[0079] When it is determined that the detected humidity value is less than the preset humidity value and a human body exists in the room, it is judged that the room needs to be humidified.

By using the humidification module, the condensate water in the sub-water storage cavity can be effectively atomized to humidify the room, ensuring the humidification quality and improving the humidification efficiency. Based on the setting of multiple humidification modules in the room, the humidification rate is facilitated.

[0100] After executing for a preset time length, the latest detected humidity value is obtained;

[0101] The preset humidity value is subtracted from the latest detected humidity value to obtain a second humidity difference value, which is compared with a preset adjustment threshold value;

[0102] When it is determined that the second humidity difference value is less than the preset adjustment threshold value, the humidification module is adjusted to a preset humidification level, the ultrasonic device included in the humidification module is operated at a second operating frequency, and the humidification valve is operated at a second opening position to perform the second stage of humidification operation; the second operating frequency is less than the first operating frequency, and the second opening position is less than the first opening position.

[0103] In this embodiment, the current target humidification level represents the level of the intensity of the current humidification.

[0104] For example, verify the instance: set the current target humidification level of the humidification module as D1, determine the first operating frequency P1 of the ultrasonic device included in the humidification module and the first opening position F1 of the humidification valve according to the current target humidification level D1, obtain the latest detected humidity value S after executing the preset time length X , difference between the preset humidity value S1 and the detected humidity value S X , S1-S X =S C2 , compare S C2 with the preset adjustment threshold Y1, when S C2 <Y1, adjust the humidification module to the preset humidification level D0, the ultrasonic device included in the humidification module executes the second stage of humidification operation at the second operating frequency P2, and the humidification valve executes the second stage of humidification operation at the second opening position F2, wherein P2<P1, F2<F1.

By obtaining the latest detected humidity value after executing the preset time length, difference between the preset humidity value and the latest detected humidity value is obtained, and comparison with the preset adjustment threshold is made, so as to judge whether the next stage of humidification operation with reduced humidification intensity can be performed after the humidification operation with strong intensity.
