Of course, when the main control unit receives the instruction of closing the sterilization module 20 from the user, the sterilization module 20 is controlled to stop running and reset to the first position.
According to the control method of the embodiment of the invention, when the environmental quality parameter is greater than or equal to the first preset threshold value, the environmental quality is extremely poor, the sterilization module 20 is controlled to start and move from the first position to the second position, so that the concentration of the purifying substances in the air duct 11 can be rapidly increased, the concentration of the purifying substances in the indoor air is rapidly increased, the time for purifying the indoor air is shortened, when the environmental quality parameter is smaller than the first preset threshold value and greater than or equal to the second preset threshold value, the environmental quality is relatively poor, the sterilization module 20 is controlled to start and move from the first position to the fifth position, so that the concentration of the purifying substances in the air duct 11 is gradually increased, the concentration of the purifying substances in the indoor air is properly increased, when the environmental quality parameter is smaller than the second preset threshold value, the indoor air quality is indicated to be still good, and the sterilization module 20 is controlled to start and keep at the first position, so that the concentration of the purifying substances in the air duct 11 is kept stable.
In some embodiments, when the environmental quality parameter is greater than or equal to a first preset threshold, controlling sterilization module 20 to activate and move from the first position to the second position further comprises:
step S23: detecting the quality of ambient air in real time and acquiring an ambient quality parameter;
step S24: when the environmental quality parameter is less than the second preset threshold, the sterilization module 20 is controlled to move from the second position to the first position.
In step S24, when the environmental quality parameter is smaller than the second preset threshold, it is indicated that the environmental quality is better controlled, and the sterilization module 20 is controlled to move from the second position to the first position, so that the concentration of the purifying substance in the air duct 11 is kept stable.
