when the server 3 judges that the temperature and the humidity in the air duct meet the condition that bacteria rapidly breed the environmental parameters, the current image and the initial image of the air duct are compared to determine that foreign matters exist on the inner wall of the air duct, and the air conditioner is controlled to heat so as to inactivate the bacteria in the air duct.
The air conditioner control method performed on the server side will be described in detail with reference to fig. 2, and as shown in fig. 2, the air conditioner control method includes:
and S110, acquiring the current environmental parameters of the air duct in the air conditioner.
The environmental parameter in wind channel includes temperature and humidity in the wind channel, and the air conditioner sends the temperature and humidity in the wind channel to intelligent terminal's APP, is uploaded to the server by the APP again.
S120, judging whether the current environmental parameters meet the bacteria rapid breeding environmental parameters; if yes, go to S130; if not, no operation is performed, namely the current flow is ended.
Taking mould as an example, when the temperature and the humidity of the environment reach certain conditions, the mould can grow rapidly, and the temperature and the humidity at the moment are environmental parameters for rapidly breeding bacteria. If the environmental parameters in the air duct are judged to accord with the rapid mould breeding condition, whether mould breeding occurs in the air duct needs to be further judged according to the image in the air duct.
And S130, acquiring a current image of an air duct in the air conditioner.
Be provided with image sensor in the wind channel of air conditioner and be used for gathering the image in the wind channel, the air conditioner sends the image in the wind channel to intelligent terminal's APP, and APP sends this image to the server.

And then, as long as the air conditioner is in a power-on state, acquiring the image in the air duct according to a specified acquisition period, namely acquiring the current image in the air duct.
The server receives the current image of the air duct and compares the current image with the initial image to judge whether foreign matters exist in the air duct or not, if the current image is obviously different from the initial image, the foreign matters exist in the air duct, and if the current image is not obviously different from the initial image, the foreign matters do not exist in the air duct.
In one possible implementation manner of the present application, as shown in fig. 3, the process of comparing the current image of the wind tunnel with the initial image by the server may include the following steps:
and S141, the server reads an initial image in the air duct obtained when the air conditioner is powered on for the first time from the local.
An initial image of the air conditioner's duct can be obtained from a local query through the unique identification of the air conditioner.
And S142, performing image segmentation on the initial image and the current image to obtain a plurality of image blocks.
And S143, comparing whether the image contents of the image blocks at the same position in the initial image and the current image are the same one by one.
S144, when the number of the image blocks with the same image content is lower than a preset ratio, determining that the initial image and the current image have obvious difference, and determining that foreign matters exist on the inner wall of the air duct.
The preset proportion can be set according to actual requirements, for example, 80%, and if the number of the same image blocks is less than 80%, it is indicated that the two images are significantly different, and it is determined that foreign matters, such as mold, exist in the air duct.
Generally, if non-bacteria foreign matters such as PU gaskets exist in the air duct, the weight of the foreign matters is light, and the foreign matters can be blown out of the air duct by air when the air conditioner is operated. And bacteria such as mould and the like can be firmly adhered to the surface of the air duct and cannot be easily blown away by wind, so that the foreign matters in the air duct can be determined by acquiring images in the air duct after the air conditioner runs and judging whether the foreign matters still exist in the air duct.
S145, when the number of the image blocks with the same image content is larger than or equal to a preset proportion, determining that no obvious difference exists between the dehumidification image and the current image, and determining that no foreign matter exists on the inner wall of the air duct.
S150, controlling the air conditioner to heat to inactivate bacteria in the air duct.
If the foreign matters exist in the air duct is judged according to the image comparison in the air duct, the air conditioner is controlled to heat, the compressor operates at high frequency, the fan of the indoor unit does not operate, meanwhile, the air deflector is closed, the temperature in the air duct reaches the bacteria inactivation temperature (for example, 60 ℃ or above), and the temperature is kept for a preset time period, for example, 20min, so that the mould in the air duct is inactivated.
And S160, controlling the air conditioner to dehumidify, and when the environmental parameters in the air duct reach the environmental parameters that bacteria do not breed, controlling the air conditioner to stop dehumidifying and start heating.
If the image in the air duct compares and judges that no clothes exist in the air duct, the air conditioner is controlled to dehumidify, the dehumidification is stopped when the humidity in the air duct is within a certain humidity range (for example, 40% -55%), and the temperature in the air duct is lower than a second preset temperature and when the environmental parameter of the air duct is determined to reach the environmental parameter that bacteria do not breed, and then the heating is started to keep the air duct dry.
According to the air conditioner control method provided by the embodiment, when the current environmental parameters of the air duct in the air conditioner are detected to meet the environmental parameters for rapid bacterial breeding, the current image of the air duct is obtained, the current image is compared with the original image of the air duct, whether foreign matters exist in the air duct is judged, and if the foreign matters exist in the air duct, the air conditioner is controlled to heat so as to inactivate the moulds in the air duct. If no foreign matter exists in the air duct, the air conditioner is controlled to dehumidify until the environmental parameters in the air duct reach the environmental parameters without bacteria growth, the dehumidification is stopped, the heating is started, and the bacteria growth in the air duct is avoided. According to the scheme, bacteria are eliminated through heating when the bacteria exist in the air duct, and when the bacteria do not exist in the air duct but the bacteria are easy to breed in environmental parameters, the air conditioner is enabled to dehumidify firstly and then heat, so that the bacteria breeding is avoided. The scheme can be implemented when the air conditioner is in a power-on state, so that the bacteria breeding can be prevented under the full application scene.
Referring to fig. 4, a flowchart of a process for determining which bacterial growth level area the current environment of the wind tunnel is located in according to an embodiment of the present application is shown, and as shown in fig. 4, the process includes the following steps:
s121, judging whether the humidity in the air duct is greater than or equal to a first preset humidity (such as 55%) and whether the temperature is greater than or equal to a first preset temperature (such as 27 ℃);
if the humidity is greater than or equal to the first preset humidity and the temperature is greater than or equal to the first preset temperature, executing S122;
if the humidity is greater than the first preset humidity and the temperature is less than the first preset temperature, executing S123;
referring to fig. 5, a schematic diagram of a mold growth environment parameter provided in an embodiment of the present application is shown.
Referring to fig. 5, an area with humidity greater than a first preset humidity (e.g., 55%) is a mold breeding area; the area with humidity less than the second preset humidity (such as 40%) is an influenza virus breeding area. Therefore, when the air conditioner is controlled to dehumidify, the breeding environment for influenza viruses cannot be created while the breeding of the mold can be inhibited, and therefore the humidity in the air duct is controlled to be more than 40%.
In different temperature ranges, the mould breeding area is divided into a mould fast breeding area, a mould low-level breeding area and a mould non-breeding area. Wherein, the area with the humidity of the environment more than 55% and the temperature more than 27 ℃ is the area where the mould is fast bred. The humidity is more than 55%, and the area with the temperature less than 27 ℃ is a low-level mold breeding area. When the humidity is less than 55% and more than 40%, meanwhile, the area with the temperature less than 27 ℃ is the area where no mold grows.
And S122, determining that the current environmental parameters of the air duct meet the environmental parameters for rapid bacterial breeding.
And S123, determining that the current environmental parameters of the air duct do not meet the environmental parameters for rapid bacterial breeding.
In another kind of application scenario of this application, in the environment that detects in the wind channel is in the bacterial fast breeding environmental parameter within range, control air conditioner dehumidifies the back, if detect humidity in the wind channel and be less than first preset humidity and be greater than or equal to second preset humidity, simultaneously, temperature in the wind channel is less than the second and predetermines the temperature, then confirms that the environmental parameter in the wind channel reaches the environmental parameter that the bacterial does not breed. Wherein the second preset temperature is lower than the first preset temperature.
For example, as shown in fig. 5, when the humidity is between 40% and 55% and the temperature is less than 24 ℃, the mold is in the non-breeding area.
According to the embodiment, according to the relation between the humiture of mould breeding and environment, it is determined whether the current environment of the air duct is a bacteria breeding level or a low level breeding area, different air conditioner control strategies are further executed according to the judgment result, and finally the environment parameters of the air conditioner air duct are adjusted to the level of not breeding mould, so that the mould breeding is avoided.
