Under the condition that the bactericidal lamp operates, the controller controls the first light sensor to be started, the light intensity in the shell is collected through the first light sensor and recorded as the first light intensity, the data are transmitted to the controller, the controller compares the first light intensity with the first standard light intensity, when the first light intensity is smaller than the first standard light intensity, the bactericidal lamp is indicated to be possible to have a fault, under the condition, the second light sensor is not started, but the bactericidal lamp is restarted after being turned off, and whether the power-on is abnormal or not is judged.
And after the germicidal lamp is restarted, the first light intensity is obtained again and compared with the first standard light intensity, if the first light intensity is not less than the first standard light intensity, the germicidal lamp is indicated to be not in failure, in this situation, the first light sensor is continuously used for obtaining the light intensity in the shell, and the second light sensor is not started.
On the contrary, if the first light intensity is still less than the first standard light intensity, the abnormal factors of electrification can be eliminated, under the condition, the controller controls the second light sensor to be started again, the light intensity in the shell is collected through the second light sensor and is recorded as the second light intensity, the data are transmitted to the controller, the controller compares the second light intensity with the first standard light intensity, when the second light intensity is also less than the first standard light intensity, the fact that the bactericidal lamp has a fault is shown, the sterilization operation cannot be continuously executed, the maintenance or the replacement is needed, and therefore the air conditioner sends out the prompt message of the fault of the bactericidal lamp, and a user is prompted to maintain or replace the bactericidal lamp.
Through such setting, can greatly improve the accuracy of judging, avoid appearing the condition that erroneous judgement bactericidal lamp breaks down.
In practical application, a person skilled in the art can flexibly set specific values of the first standard light intensity for different types of germicidal lamps through experiments, as long as whether the germicidal lamp fails or not can be judged through the critical point determined by the first standard light intensity.
It should be noted that, if the second light intensity is not less than the first standard light intensity, it indicates that the germicidal lamp is not failed, and it also indicates that the first light sensor is failed, in this case, it is preferable to enable the air conditioner to send a message indicating that the first light sensor is failed, so as to prompt the user to repair or replace the first light sensor.
It should be noted that, in practical applications, a sound device may be installed on the indoor unit, and when the germicidal lamp fails, the sound device (such as a buzzer, a voice broadcaster, etc.) is made to sound to prompt the user that the germicidal lamp fails, or an indicator lamp may be installed on the indoor unit, and when the germicidal lamp fails, the indicator lamp displays a color of the failure to prompt the user that the germicidal lamp fails, or the indicator lamp and the sound device are combined together to prompt the user that the germicidal lamp fails, and so on.
Preferably, the step of causing the air conditioner to issue the warning message of the malfunction of the germicidal lamp includes: the indicator light on the indoor unit is changed into red. In the case where it is not necessary to cause the air conditioner to issue the warning message indicating the failure of the germicidal lamp, the indicator lamp may be turned on or off.

If the second light intensity is not less than the first standard light intensity, it indicates that the germicidal lamp is not in failure, and the air conditioner does not need to send out a prompt message of the germicidal lamp failure; it is also explained that the first light sensor is out of order, in which case, it is preferable to make the air conditioner send out a message indicating that the first light sensor is out of order so as to prompt the user to repair or replace the first light sensor.
In addition, it should be noted that when the second light intensity is not less than the first standard light intensity, a new round of detection determination needs to be performed, in this case, it has been determined that the first light sensor may be faulty, and it is preferable that the light intensity in the housing is not collected by the first light sensor, but the light intensity in the housing is collected by the second light sensor directly, similarly to the first embodiment and the second embodiment, it is preferable that the light intensity in the housing is collected by the second light sensor after a preset time interval, and of course, before, at the same time of, or after the second light intensity is collected again, the opening angle of the air deflector is obtained again, and the third light intensity is collected by the third light sensor, so as to determine the first standard light intensity again.
In addition, it should be noted that if the first light intensity is not less than the first standard light intensity, it indicates that the germicidal lamp is not failed, in which case, it is not necessary to make the air conditioner send out a notification message that the germicidal lamp is failed.
In addition, it should be noted that, in practical applications, a person skilled in the art may flexibly adjust the execution order of the above steps, for example, step S300 and step S400 may be executed simultaneously, or step S400 may be executed first and then step S300 may be executed; still alternatively, steps S300, S400 and S500 may be performed first, and then step S100 and step S200 may be performed, etc., and such flexible adjustment and change may not depart from the principle and scope of the present invention, and should be limited within the protection scope of the present invention.
In addition, it should be noted that, in practical applications, a sound device may be installed on the indoor unit, and when the germicidal lamp fails, the sound device (e.g., a buzzer, a voice broadcaster, etc.) is made to sound to prompt the user that the germicidal lamp fails, or an indicator may be installed on the indoor unit, and when the germicidal lamp fails, the indicator is made to display a failure color to prompt the user that the germicidal lamp fails, or the combination of the indicator and the sound device is used to prompt the user that the germicidal lamp fails, and so on.
Preferably, the step of causing the air conditioner to issue a warning message of the failure of the germicidal lamp includes: the indicator light on the indoor unit is changed into red. In the case where it is not necessary to cause the air conditioner to give a warning message of the failure of the germicidal lamp, the indicator lamp may be turned green or off.
Example four
On the basis of the second embodiment, the following steps are added: acquiring the light intensity outside the shell, and recording as a third light intensity; acquiring an opening angle of an air deflector of an indoor unit; and acquiring corresponding preset light intensity according to the third light intensity and the opening angle, and taking the preset light intensity as the first standard light intensity. The sequence of each step can be referred to as implementation three, and is not described in detail herein.
EXAMPLE five
On the basis of the first, second, third or fourth embodiment, the control method of this embodiment further includes the following steps:
if the first light intensity or the second light intensity is greater than the first standard light intensity, comparing the first light intensity or the second light intensity with the second standard light intensity; if the first light intensity or the second light intensity is smaller than the second standard light intensity, the air conditioner sends out prompt information that the sterilizing effect of the sterilizing lamp is poor, and exemplarily, an indicator lamp on the indoor unit is changed into yellow; the second standard light intensity is greater than the first standard light intensity.
When first light intensity is greater than first standard light intensity, explain that the bactericidal lamp does not break down, can also continue the operation of disinfecting, under this situation, can continue to make first light intensity and second standard light intensity carry out the comparison, when first light intensity is less than second standard light intensity, explain that the bactericidal lamp can also continue the operation of disinfecting, however, the bactericidal effect of bactericidal lamp is relatively poor, consequently, make the air conditioner send the relatively poor prompt message of bactericidal effect of bactericidal lamp, change the bactericidal lamp as early as possible in order to inform the user.
Similarly, under the condition that first light sensor breaks down, when second light intensity is greater than first standard light intensity, continue to make second light intensity and second standard light intensity compare, when second light intensity is less than second standard light intensity, explain the bactericidal lamp although can also continue the operation of disinfecting, but the bactericidal effect of bactericidal lamp is relatively poor, consequently makes the air conditioner send the less prompt message of bactericidal lamp bactericidal effect to inform the user to change the bactericidal lamp as early as possible.
That is, when the first light intensity or the second light intensity is smaller than the first standard light intensity, it indicates that the germicidal lamp is out of order, the germicidal operation is not performed, and the germicidal lamp needs to be immediately repaired or replaced; when the first light intensity or the second light intensity is greater than the first standard light intensity and less than the second light intensity, it is described that the germicidal lamp can continue to perform the germicidal operation, but the germicidal effect is poor and needs to be replaced as soon as possible.
In practical application, a person skilled in the art can flexibly set specific values of the first standard light intensity and the second standard light intensity for different types of germicidal lamps through tests, as long as whether the germicidal lamp fails or not can be judged through the critical point determined by the first standard light intensity and whether the germicidal effect of the germicidal lamp is poor or not can be judged through the critical point determined by the second standard light intensity.
