Preferably, the certain water level value is the highest water level value of the water storage device 19 and/or set by the user.
In order to prevent the air in the bathroom from being too dry due to the fact that the dehumidifying device dehumidifies all the time, when the external humidity detected by the humidity sensor 21 reaches a certain humidity, the control module controls the dehumidifying device to stop working. Preferably, the certain humidity can be set by the user or can be a default of the system.
In order to save electricity, when the air quality sensor 10 detects that the external air quality reaches a certain value, the air purification device is controlled to stop working. The certain air quality can be set by a user or can be default of the system.
