In the present preferred embodiment, first, in step S201, the controller detects the number of harmful bacteria in the indoor air using the harmful bacteria detector 21, acquires or receives the indoor temperature and the indoor humidity detected by the temperature and humidity sensor, and controls the operation state of the sterilization apparatus 2 according to the number of indoor harmful bacteria, the indoor temperature and the indoor humidity.
Specifically, in step S202, when the number of harmful bacteria in the room is greater than or equal to the first preset number of harmful bacteria in the room and less than the second preset number of harmful bacteria in the room, the controller calculates a first bacteria growth rate value according to the room temperature and the room humidity, and of course, the present invention does not limit the specific calculation mode thereof, and a person skilled in the art may set the calculation mode according to the actual use requirement, so long as the calculation result can characterize the bacteria growth rate value, for example, the bacteria growth rate value may be represented by the product of the room temperature and the room humidity, and the operation state of the sterilization device is controlled according to the first bacteria growth rate value. The propagation speed and the indoor temperature of harmful bacteria are closely related to the indoor humidity, so that according to the quantity of the indoor harmful bacteria, the indoor temperature and the indoor humidity jointly control the running state of the sterilizing device 2, the harmful bacteria in the air can be timely, accurately and effectively sterilized, and meanwhile, the problem that the sterilizing device 2 is always in the running state and further causes the problem of high energy consumption of the washing air conditioner for meeting the health requirements of users can be effectively avoided.
It should be noted that the present invention does not limit the specific number of the harmful bacteria in the second preset chamber; as a preferred embodiment, the number of harmful bacteria in the first preset room is 2500cfu/m 3, and the number of harmful bacteria in the second preset room is 7500cfu/m 3, so that the health requirement of a user can be effectively ensured, and the energy consumption of the water washing air conditioner can be effectively reduced.
Specifically, in step S203 and step S204, if the first bacteria growth speed value is smaller than the first preset bacteria growth speed value, which indicates that the speed of the harmful bacteria propagating is not too fast, the controller controls the sterilization device 2 to alternately perform the steps of running for the first preset time period and then suspending the running for the second preset time period with the first preset running power, so that the energy consumption of the water washing air conditioner can be effectively reduced while the health requirement of the user is effectively ensured. If the first bacteria growth speed value is greater than or equal to the first preset bacteria growth speed value, which indicates that the harmful bacteria propagation speed is too high, the controller controls the sterilization device 2 to continuously operate at the first preset operation power so as to timely sterilize the harmful bacteria in the air, and a good and healthy environment is provided for the user.
Further, in step S205, in the case that the number of harmful bacteria in the room is equal to or greater than the number of harmful bacteria in the second preset room, the controller calculates a second bacteria growth rate value according to the room temperature and the room humidity, and controls the operation state of the sterilization device 2 according to the second bacteria growth rate value. Of course, the specific calculation mode of the method is not limited, and a person skilled in the art can set the method according to the actual use requirement, so long as the calculation result can represent the bacterial growth rate value, for example, the bacterial growth rate value can be represented by the product of the indoor temperature and the indoor humidity.
It should be noted that, the present invention does not limit the specific calculation modes of the first bacterial growth rate value and the second bacterial growth rate value, and those skilled in the art can set the calculation modes according to actual situations; preferably, the first and second bacteria growth rate values are positively correlated with the indoor temperature and the indoor humidity.
Specifically, in step S206 and step S207, if the second bacteria growth rate value is smaller than the second preset bacteria growth rate value, which indicates that the speed of the harmful bacteria propagating is not too fast, the controller controls the sterilization device 2 to alternately perform the step of operating for the third preset period of time and then suspending the operation for the fourth preset period of time at the second preset operation power, wherein the first preset operation power is smaller than the second preset operation power, so as to effectively reduce the energy consumption of the water-washing air conditioner. And if the second bacteria growth speed value is larger than or equal to the second preset bacteria growth speed value, and the harmful bacteria propagation speed is too high, the controller controls the sterilizing device 2 to continuously operate at the second preset operating power.
It should be noted that, the specific setting values of the first preset operation power and the second preset operation power are not limited, and may be set by a user or may be set according to the actual operation condition of the water-washing air conditioner, which is not limited. In addition, it should be noted that the specific setting values of the first preset duration, the second preset duration, the third preset duration and the fourth preset duration are not limited in the present invention, and the first preset duration, the second preset duration, the third preset duration and the fourth preset duration may be the same or different, which may be understood that a person skilled in the art may set the setting values according to actual use conditions.
Thus far, the technical solution of the present invention has been described in connection with the preferred embodiments shown in the drawings, but it is easily understood by those skilled in the art that the scope of protection of the present invention is not limited to these specific embodiments. Equivalent modifications and substitutions for related technical features may be made by those skilled in the art without departing from the principles of the present invention, and such modifications and substitutions will fall within the scope of the present invention.
