For example, the working mode further includes the working time, the working frequency and the like of the air conditioner indoor unit 10.

[0039] Step S204: determining whether the working mode is the heating mode.

[0040] In some other embodiments, the step of determining whether the working mode is the heating mode is followed by, i.e. is followed by step S204:

[0041] Step S206: if not, controlling the air conditioner indoor unit 10 to operate according to the working mode. That is, as long as the air conditioner indoor unit 10 is not in the heating mode, the air conditioner indoor unit 10 operates according to the user-set working mode. That is, as long as the air conditioner indoor unit 10 is not in the heating mode, the air conditioner indoor unit 10 executes whatever the user-set working mode of the air conditioner indoor unit 10 is. For example, if the working mode includes the cooling mode, the air conditioner indoor unit 10 executes the cooling function. For example, if the working mode includes the cooling mode and the cooling time, the air conditioner indoor unit 10 executes the cooling function according to the user-set cooling time. For example, the user-set working mode includes the water washing mode, the air conditioner indoor unit 10 executes the water washing function. This makes the functions of the air conditioner indoor unit 10 more diversified to meet different needs of the user.

[0042] In some other embodiments, the step of calculating the time during which the air conditioner indoor unit 10 is in the heating mode is followed by, i.e. is followed by step S208:

[0043] Step S210: When the time of the air conditioner indoor unit 10 in the heating mode is less than the first preset time, control the air conditioner indoor unit 10 to run according to the working mode.

[0044] In the embodiment, the specific value of the first preset time is not limited, which can be selected according to the needs. For example, the value range of the first preset time is 0.8 hours to 1.2 hours. Specifically, the first preset time is 1 hour.

[0045] When the time of the air conditioner indoor unit 10 in the heating mode is less than the first preset time, control the air conditioner indoor unit 10 to run according to the working mode set by the user. That is, if the working mode of the air conditioner indoor unit 10 is the heating mode, and the time of the heating mode is within the first preset time range. The air conditioner indoor unit 10 runs according to the working mode set by the user. Here, the working mode includes the heating time, the heating frequency, etc. Within the first preset time, the indoor humidity is relatively appropriate, and the air conditioner indoor unit 10 runs according to the set working mode to save cost.

[0048] In the embodiment, the specific value of the second preset time is not limited, which can be selected according to the needs. For example, the value range of the second preset time is 0.8 hours to 1.2 hours. Specifically, the second preset time is 1 hour.

[0049] In the embodiment, the specific value of the third preset time is not limited, which can be selected according to the needs. For example, the value range of the third preset time is 0.8 hours to 1.2 hours. Specifically, the third preset time is 1 hour.

[0050] When the time of the air conditioner indoor unit 10 in the heating mode is greater than the first preset time, at this time, the indoor humidity is relatively low, that is, the indoor is relatively dry. At this time, controlling the humidifying device 110 to open for the second preset time can improve the indoor humidity, avoid the indoor being too dry, and improve the comfort degree of people.

[0051] The humidifying device 110 is controlled to cyclically execute the opening for the second preset time and the closing for the third preset time. That is, the humidifying device 110 is controlled to alternately open for the second preset time and close for the third preset time, that is, the humidifying device 110 is controlled to open for a period of time and close for a period of time. This can improve the indoor humidity, avoid that the indoor is too dry, and improve the comfort of people. This can also avoid that the indoor is too humid, causes waste and makes the indoor too humid. This makes the humidifying device 110 automatically open and close, and saves people from constantly thinking about the opening and closing of the humidifying device 110 when ensuring that the indoor is in a comfortable humidity range.

[0052] In some other embodiments, after the step of controlling the humidifying device 110 to cyclically execute the opening for the second preset time and the closing for the third preset time, that is, after the step S212, the method further comprises:
