All other embodiments, which can be made by one of ordinary skill in the art without undue burden from the disclosure, are within the scope of the disclosure.
First embodiment
Fig. 1 shows a flowchart of a control method of an air conditioner according to a first embodiment of the present disclosure.

step S2, if the current bacterial concentration value is smaller than the preset bacterial concentration value, adjusting the air inlet quantity passing through the sterilization range of the ultraviolet lamp 110 to be the maximum value, and controlling the single working time of the ultraviolet lamp 110 to be the minimum value;
step S3, if the current bacterial concentration value is greater than or equal to the preset bacterial concentration value, adjusting the air inlet quantity passing through the sterilization range of the ultraviolet lamp 110 to be an optimal value;
s4, acquiring a current indoor temperature value;
s5, if the current indoor temperature value is not equal to the set temperature value, acquiring the current indoor temperature change rate value;
step S6, if the current indoor temperature change rate value is smaller than the set temperature change rate value, the air inlet passing through the sterilization range of the ultraviolet lamp 110 is kept unchanged, the air speed at the air inlet is increased, and the working time of the ultraviolet lamp 110 is prolonged.
The present embodiment provides a control method of an air conditioner, which can realize effective sterilization of the air conditioner 100 and meet the requirement of customers on temperature effect. Specifically, the control method firstly obtains the current bacteria concentration value of the indoor air, then compares the bacteria concentration value with the preset bacteria concentration value, and adjusts the working state of the ultraviolet lamp 110 according to the comparison result, so that the air entering the air conditioner 100 is effectively sterilized, the use cost is saved, and the service life of the ultraviolet lamp 110 is prolonged. When the air intake of the ultraviolet lamp 110 is the optimal value, the requirement of the user on the temperature is considered, and at this time, the current indoor temperature value is required to be obtained first to determine whether the temperature value is equal to the temperature value set by the user; if yes, maintaining the working state of the air conditioner 100; if not, the current indoor temperature change rate value needs to be further obtained to judge whether the temperature change rate value is the same as the temperature change rate value set by the user, if so, the working state of the air conditioner 100 is maintained; if not, the sterilization effect of the ultraviolet lamp 110 is improved by extending the ultraviolet working time, and the air speed at the air inlet is increased to improve the cooling/heating effect of the air conditioner 100.
62 specifically, if the current bacteria concentration value is smaller than the preset bacteria concentration value, which indicates that the bacteria concentration of the current indoor air is at a healthy level, at this time, the air intake of the sterilization range passing through the ultraviolet lamp 110 is adjusted to be the maximum, and the single operation time of the ultraviolet lamp 110 is controlled to be the minimum, so as to ensure the cooling/heating effect of the air conditioner 100 to meet the temperature requirement of the customer. If the current bacteria concentration value is greater than or equal to the preset bacteria concentration value, it indicates that the bacteria concentration of the current indoor air is at an unhealthy level, at this time, the air intake of the sterilization range passing through the ultraviolet lamp 110 needs to be adjusted to be an optimal value, and the ultraviolet lamp 110 is controlled to work, so that the effect of the ultraviolet lamp 110 on thoroughly sterilizing bacteria in the air entering the air conditioner 100 is satisfied by reducing the air intake, thereby improving the quality of the indoor air.
For example, but not limited to, the single operation time of the ultraviolet lamp 110 is 0 to 30min. The minimum value of the single operation time of the ultraviolet lamp 110 is 0 minutes, namely, the ultraviolet lamp 110 stops operating at the moment; the maximum value of the single operation time of the ultraviolet lamp 110 is 30 minutes, that is, the ultraviolet lamp 110 provides the maximum sterilization effect at this time.
By the above, the embodiment of the disclosure dynamically adjusts the air inlet amount passing through the sterilization range of the ultraviolet lamp 110, so that the air conditioner 100 can realize effective sterilization and simultaneously can also consider the temperature effect of the air conditioner 100, thereby being beneficial to improving the use experience of users.

Specifically, when the indoor air quality is good, the ultraviolet lamp 110 is controlled to be in a stop working state, and the wind shield 130 is controlled to rotate to the maximum angle, so that the whole air inlet quantity is improved; when the indoor air quality is poor, the ultraviolet lamp 110 is controlled to work, and meanwhile, the wind shield 130 is controlled to rotate to an optimal angle for air intake, so that the air entering the air conditioner 100 is thoroughly sterilized on the premise of smaller air intake, and the sterilization effect is improved.
