If the current operation mode of the air conditioner is the cooling operation mode, that is, the step S29 is executed, the current operation mode of the air conditioner is judged to be the cooling operation mode, then the step S30 is executed, the N8 ultraviolet lamps are controlled to be turned on and turned off after the eighth preset sterilization time t8 is continued, specifically, the 5 ultraviolet lamps are controlled to be turned on and turned off after the eighth preset sterilization time t8 is continued, and therefore the accurate sterilization operation of the air conditioner when the air conditioner works with high-grade air inlet quantity in the cooling operation mode is met. If the current air conditioner operation mode is not the heating operation mode and is not the cooling operation mode, step S31 is executed, and the air conditioner continues to operate in the current operation mode.

In order to ensure the operational reliability of the air conditioner, the indoor and outdoor temperature difference Δt is not more than 44 ℃.
Specifically, the preset sterilization time for the ultraviolet lamp to be turned on is in direct proportion to the number of the turned-on ultraviolet lamps, namely, when 1 ultraviolet lamp is turned on, the ultraviolet lamp is turned off after the first preset sterilization time t1 is continued; when 2 ultraviolet lamps are started, the ultraviolet lamps are closed after a third preset sterilization time t3 is continued; when the 3 ultraviolet lamps are started, the ultraviolet lamps are closed after the fifth preset sterilization time t5 is continued; when the 4 ultraviolet lamps are started, the seventh preset sterilization time t7 is continued and then the ultraviolet lamps are closed; when the 5 ultraviolet lamps are turned on, the eighth preset sterilization time t8 is continued and then turned off, so that t1 < t2=t3 < t4=t5 < t6=t7 < t8.
Therefore, in the air conditioner sterilization control method of the embodiment, by obtaining the opening angle θ of the air inlet baffle 13 and the time T required for the opening angle θ of the air inlet baffle 13, and judging the operation mode of the current air conditioner, if the opening angle θ of the air inlet baffle 13 is in the same range segment (for example, θ1 < θ+.θ2), if the current air conditioner is in the heating operation mode, the first number of ultraviolet lamps is controlled to be turned on, and if the current air conditioner is in the cooling operation mode, the second number of ultraviolet lamps is controlled to be turned on, and the second number is greater than the first number, specifically, the difference between the second number and the first number in the embodiment is not greater than the preset difference, for example, not greater than 2, and the first number is in direct proportion to the opening angle θ of the air inlet baffle 13, and the second number is in direct proportion to the opening angle θ of the air inlet baffle 13.
Related researches show that when the ultraviolet lamp works, the surface optimal temperature is 40 degrees, the output of the ultraviolet lamp can be influenced by the fact that the temperature is too high or too low, and then the sterilization effect is influenced. Therefore, the air conditioner sterilization control method can be suitable for different running modes of an air conditioner, ensure the sterilization effect and effectively prolong the service life of the ultraviolet lamp.
