The propagation speed and the indoor temperature of harmful bacteria are closely related to the indoor humidity, so that the harmful bacteria in the air can be sterilized timely, accurately and effectively according to the number of the indoor harmful bacteria, the indoor temperature and the indoor humidity which jointly control the operating state of the sterilizing device 2, and meanwhile, the problem that the sterilizing device 2 is always in the operating state to meet the health requirements of users and further cause the high energy consumption of the washing air conditioner can be effectively avoided.
It should be noted that the invention does not limit any specific value of the number of harmful bacteria in the second preset chamber; as a preferred embodiment, the number of harmful bacteria in the first predetermined room is 2500cfu/m3The number of harmful bacteria in the second preset room is 7500cfu/m3Therefore, the health requirements of users can be effectively guaranteed, 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 propagation speed of harmful bacteria is not too fast, the controller controls the sterilization device 2 to alternately perform the step of operating at the first preset operating power for a first preset time period and then suspending operation for a second preset time period, so as to effectively ensure the health requirement of the user and also effectively reduce the energy consumption of the water washing air conditioner. 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 at the moment, the controller controls the sterilization device 2 to continuously operate at the first preset operation power, so that the harmful bacteria in the air can be sterilized in time, and a good and healthy environment is provided for users.
Further, in step S205, in the case that the indoor harmful bacteria count is equal to or greater than the second preset indoor harmful bacteria count, the controller calculates a second bacteria growth rate value according to the indoor temperature and the indoor humidity, and controls the operation state of the sterilization apparatus 2 according to the second bacteria growth rate value. Of course, the present invention does not limit the specific calculation manner, and those skilled in the art can set the calculation result according to the actual use requirement as long as the calculation result can represent the bacteria growth speed value, for example, the bacteria growth speed 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 any specific calculation manner of the first bacterial growth speed value and the second bacterial growth speed value, and a person skilled in the art can set the calculation manner 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 speed value is smaller than a second preset bacteria growth speed value, which indicates that the propagation speed of harmful bacteria is not too fast, the controller controls the sterilization device 2 to alternately perform the step of operating at a second preset operating power for a third preset time period and then suspending the operation for a fourth preset time period, wherein the first preset operating power is smaller than the second preset operating power, so as to effectively reduce the energy consumption of the water washing air conditioner. If the second bacteria growth speed value is greater than or equal to the second preset bacteria growth speed value, which indicates that the propagation speed of harmful bacteria is too high, the controller controls the sterilization device 2 to continuously operate at the second preset operation power.
It should be noted that, the present invention does not limit any specific setting value of the first preset operating power and the second preset operating power, and the setting value may be set by a user, or may be set according to an actual operating condition of the water washing air conditioner, which is not restrictive. In addition, it should be further noted that, the present invention does not set any limit to specific setting values of the first preset time period, the second preset time period, the third preset time period, and the fourth preset time period, and the first preset time period, the second preset time period, the third preset time period, and the fourth preset time period may be the same or different, and it can be understood that a person skilled in the art can set the time periods by himself or herself according to actual use conditions.
So far, the technical solutions of the present invention have been described in connection with the preferred embodiments shown in the drawings, but it is apparent to those skilled in the art that the scope of the present invention is not limited to these specific embodiments. Equivalent changes or substitutions of related technical features can be made by those skilled in the art without departing from the principle of the invention, and the technical scheme after the changes or substitutions can fall into the protection scope of the invention.
