Fig. 5 is a schematic structural diagram of an embodiment of a bacteria detection apparatus for an air conditioner according to the present invention. As shown in fig. 5, the bacteria detection apparatus 100 includes a first control unit 110, a first determination unit 120, a second control unit 130, and a second determination unit 140.

Specifically, when the second determination unit 140 determines that the air conditioner interior bacteria content is qualified, the display unit displays a corresponding prompt message to prompt the air conditioner interior bacteria content to be qualified, for example, displays a notification message to notify the user that the air conditioner interior bacteria content is qualified.
According to the embodiment of the invention, whether the indoor air quality is qualified or not and whether the bacteria content in the air conditioner is qualified or not can be detected only through the bacteria detection module arranged at the air outlet by controlling the forward and reverse rotation of the fan, so that the problem that the single bacteria detection module cannot detect the bacteria content of the inlet air and the outlet air simultaneously is solved.
FIG. 6 is a schematic structural diagram of another embodiment of the bacteria detection apparatus provided by the present invention. As shown in fig. 6, the bacteria detection apparatus 100 further includes a determination unit 150.
The determining unit 150 is configured to determine a position where the content of bacteria in the air conditioner exceeds a predetermined value according to whether a rotational speed control signal for controlling the fan exceeds a predetermined value if the second determining unit 140 determines that the content of bacteria in the air conditioner is not qualified.
Specifically, when the filter screen is dirty and blocked, the load of the fan is reduced due to the reduction of the air intake, and the rotation speed control signal of the motor is also reduced synchronously, so that the determining unit 150 can acquire the rotation speed control signal of the motor and determine the dirty and blocked condition of the filter screen according to the comparison result between the acquired rotation speed control signal and the preset value. For example, the rotation speed control signal of the PG speed regulating motor is a hall pulse signal, and the preset value can be a preset pulse number; the rotation speed control signal of the dc motor is a VSP rotation speed control signal, which is a dc voltage signal, and the preset value may be a preset voltage value. If the rotating speed control signal is detected to exceed the preset value, the determining unit 150 determines that the bacterial content of the air conditioner filter screen exceeds the standard. When the rotating speed control signal exceeds a preset value, a certain amount of filth blockage of the air conditioner filter screen is judged (the filth blockage condition is not enough to trigger the filth blockage protection of the air conditioner), bacteria are most easily bred in the filter screen at the moment, and the bacteria at the position of the filter screen exceed the standard. If the detected rotating speed control signal does not exceed the preset value, it indicates that the filter screen of the air conditioner is not dirty and blocked, and the determining unit 150 determines that the content of bacteria in the air duct of the air conditioner exceeds the standard, such as an evaporator and/or fan blades in the air conditioner.
Optionally, the apparatus 100 further includes a display unit (not shown) configured to display a corresponding prompt message to prompt the air conditioner filter screen that the bacteria content is excessive if the second determination unit 140 determines that the bacteria content of the air conditioner filter screen is excessive, for example, to display a notification message to notify a user that the bacteria content at the position of the air conditioner filter screen is excessive and that cleaning or sterilization is required. If the bacteria content in the air duct of the air conditioner is judged to be over standard, corresponding prompt information is displayed to prompt the over standard of the bacteria content in the air duct of the air conditioner, for example, notification information is displayed to notify a user that the bacteria content in the air duct of the air conditioner is over standard and cleaning or sterilization is needed.
Optionally, the second determination unit 140 is further configured to detect, by the bacteria detection module again after the filter screen is cleaned, whether the number of bacterial colonies in the air discharged from the air outlet of the air conditioner exceeds a preset threshold; and if the bacteria content in the air discharged from the air outlet of the air conditioner exceeds the preset threshold value, judging that the bacteria content in the air duct of the air conditioner exceeds the standard.
Specifically, a user feedback button may be provided for feedback after the user cleans the filter screen. For example, a "filter screen cleaned" button is displayed, and after the user cleans the filter screen, the user may click the "filter screen cleaned" button to determine that the filter screen has been cleaned, and the second determination unit 140 detects whether the bacteria content in the air discharged from the air conditioner through the air outlet exceeds the preset threshold value again through the bacteria detection module.
And if the bacteria content does not exceed the preset threshold value, determining that the bacteria content in the air conditioner is qualified. Optionally, when the bacteria content in the air conditioner is judged to be qualified, displaying corresponding prompt information to prompt that the bacteria content in the air conditioner is qualified, for example, displaying notification information to notify a user that the bacteria content in the air conditioner is qualified.
If the bacterial colony number still exceeds the preset threshold value, the fact that bacteria in the air duct of the air conditioner exceed the standard can be judged, optionally, corresponding prompt information can be displayed to prompt that the content of the bacteria in the air duct of the air conditioner exceed the standard, for example, notification information is displayed to notify a user that the content of the bacteria in the air duct of the air conditioner exceeds the standard, and cleaning or sterilization treatment is needed.

According to the scheme provided by the invention, the fan is controlled to rotate forwards and backwards, and whether the indoor air quality is qualified or not and whether the bacteria content in the air conditioner is qualified or not can be detected only through the bacteria detection module arranged at the air outlet, so that the problem that the single bacteria detection module cannot detect the bacteria content of the inlet air and the outlet air at the same time is solved; according to the technical scheme of the invention, when the bacteria in the air conditioner exceed the standard, the position where the content of the bacteria in the air conditioner exceeds the standard can be determined according to whether the rotating speed control signal for controlling the fan exceeds the preset value; according to the technical scheme of the invention, when the indoor air quality is detected to be unqualified or the bacteria in the air conditioner exceed the standard, corresponding prompt information can be displayed to remind a user of sterilization treatment.
