[0048] The preferred embodiments of the present application will be described below with reference to the accompanying drawings. It should be understood by those skilled in the art that the embodiments are only used to explain the technical principles of the present application and are not intended to limit the scope of protection of the present application. Those skilled in the art can make adjustments as needed to adapt to specific application occasions. For example, although the specific embodiments in the description are described by taking one air conditioner as an example, the present application can obviously be controlled by the control method of the present application by using other similar means, such as taking two or more air conditioners, etc.

[0049] In addition, it should be noted that in the description of the present application, unless otherwise explicitly specified and limited, the term "arrangement" and the like should be understood broadly, for example, it can be fixedly connected, or detachably connected, or integrally connected; it can be mechanically connected, or electrically connected; it can be directly connected, or indirectly connected through an intermediate medium, etc. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0050] In order to solve the problem that the conventional air conditioner does not have the ability to effectively purify the air, and the air conditioner with the ability to purify the air cannot perform targeted purification treatment according to the air quality of different areas in the current space, the present application provides a control method of an air conditioner. In order to better describe the control method of the present application, the structure of the air conditioner involved in the present application will be described first.

[0051] The air conditioner (not shown in the figure) comprises an air quality sensor (not shown in the figure) and an air purification part (not shown in the figure). The air quality sensor is arranged to be able to detect the quality of the air input into the air conditioner from the air inlet (not shown in the figure) of the air conditioner. Specifically, the air quality sensor can be arranged inside the air inlet of the air conditioner, or arranged at a position outside the air inlet of the air conditioner, etc. The air purification part is arranged to be able to purify the air input into the air conditioner from the air inlet of the air conditioner. Specifically, the air purification part can also be arranged inside the air inlet of the air conditioner, or arranged at a position outside the air inlet of the air conditioner, etc. In the present embodiment, the air purification part comprises an ultraviolet lamp, a photocatalyst plate and a control circuit box, and the control circuit box is electrically connected with the ultraviolet lamp.

[0052] The common air purification methods in the prior art mainly include adsorption method, room temperature catalytic oxidation method, etc. Among them, the adsorption method uses active carbon and other adsorption materials to adsorb volatile organic compounds and harmful gases in the air, but these adsorption materials cannot decompose these pollutants, and after saturation, if not replaced in time, these adsorption materials can easily become a new pollution source to release pollutants again, so it is necessary to replace the adsorption materials regularly to maintain their purification performance. In addition, the adsorption method cannot kill bacteria and disinfect, and after long-term use, the surface of the adsorption material is easy to breed bacteria, viruses and other pathogens, which is not conducive to air purification. The room temperature catalytic oxidation method uses potassium permanganate and other strong oxidizing agents to oxidize and decompose pollutants in the air, but its decomposition efficiency is low, a large amount of oxidizing agent is needed, it is difficult to adapt to the existing air conditioner structure, and with the increase of use time, the oxidation effect of the oxidizing agent is easy to deteriorate, so it also needs to be replaced regularly to maintain the removal effect.

[0053] In the present application, the photocatalytic purification method can completely decompose volatile organic compounds and harmful inorganic gases in the air into harmless CO2 and H2O, and the strong oxidizing free radicals produced can also kill bacteria and viruses. In addition, as a catalyst, the photocatalytic material will not be consumed during the reaction, and there is no need to replace the material, the operating cost is low, and the long-term effect is stable. Moreover, the photocatalyst plate has a grid structure and has the structural characteristics of low resistance and air permeability, which can ensure that the air volume and refrigeration and heating functions of the air conditioner are not affected, and can be applied to air conditioners and other purification products with small internal space without changing the existing structure of the air conditioner, and can effectively remove indoor volatile organic compounds and harmful inorganic gases. It has good removal effect on formaldehyde, benzene, ammonia, TVOC, etc., and also has good sterilization effect on bacteria and viruses. It can remove volatile organic compounds and harmful gases, viruses and bacteria while ensuring the air volume and refrigeration and heating performance of the air conditioner. The photocatalyst plate of the present application can carry sufficient photocatalyst, and can also be used with ultraviolet lamps. When applied to air conditioners and other products, it can still ensure the purification effect in the dark environment inside the air conditioner.

[0054] The structure of the air conditioner of the present application is described above, and next, the control method of the air conditioner of the present application is described. As shown in Figure 1 Figure 1 The flow chart of the main steps of the present application, the control method of the present application mainly includes the following steps:

[0055] S1, control the air conditioner to supply air to different areas of the air space to be adjusted in turn, and obtain the air quality parameters A of different areas through the air quality sensor.

[0056] S2, compare A with the preset air quality parameter to determine whether there is an area that needs to be purified.

[0057] ​S3. When there is an area that needs air purification, execute the following: control the air conditioner to supply air to the area where the air needs purification and start the air purification unit.

[0058] The air conditioner control method of the present invention enables the air conditioner to obtain the air quality of different areas of the same air space to be regulated by simply setting an air quality sensor at the air inlet of the air conditioner, and to send air to the corresponding area according to the air quality condition, and to purify the air through the air purification unit. Correspondingly, it can also reduce the cost of setting multiple air quality sensors.

[0059] like Figure 2 As shown, Figure 2 This is a flowchart detailing the steps of a preferred embodiment of the present invention. Taking one air conditioner as an example, a preferred embodiment of the control method of the present invention further includes the following steps:

[0060] S11. Obtain parameters for different areas of the air space to be regulated.

[0061] In this step, the parameters of different areas of the air space to be regulated can be the volume of each area, or the position parameters of the air guide vanes of the air conditioner that match each area of ​​the air space to be regulated. Specifically, the position parameters can be the rotation angle and rotation direction of the air guide vanes.

[0062] The parameters for different areas of the air space to be regulated can be manually set by the user through an app, or the air conditioner can automatically acquire these parameters during its first run based on the current space conditions, using image recognition and the air deflector's rotation angle and direction. Specifically, this could be the time required for air quality improvement when the air deflector is maintained at a certain angle and direction. Alternatively, the user can manually adjust the parameters based on the automatically set settings.

[0063] S12. Control the air conditioner to sequentially deliver air to different areas of the space to be conditioned, and obtain the air quality parameters A of different areas through the air quality sensor.

[0064] S13. Compare A with preset air quality parameters to determine if there are areas that require air purification.

[0065] S14. When there is an area that needs air purification, execute the following: control the air conditioner to supply air to the area where the air needs purification and start the air purification unit.

[0066] In this step, the air supply of the air conditioner can be controlled according to the air quality of the area where the air to be purified is located.

[0067] For example, the air conditioner can be controlled to supply air to the air purification region in the order of air quality from low to high. Specifically, the air quality can be lower, the air supply speed can be higher, and the air quality can be higher, the air supply speed can be lower, according to the volume V of the corresponding different regions, at the same air supply time. In addition, the air supply speed can remain the same at different air qualities, and the air supply time can be set to be different according to the corresponding V and air quality, for example, the air quality can be lower, the air supply time can be longer, and the air quality can be higher, the air supply time can be shorter. Of course, it can also be replaced by supplying air to the corresponding regions at different air supply speeds and air supply times according to the air quality of different regions, as long as the unit time and unit volume of air supply of the region with lower air quality is higher, and the unit time and unit volume of air supply of the region with higher air quality is lower.

[0068] In this step, in addition to controlling the air supply of the air conditioner according to the air quality of the air purification region, it can also be replaced by controlling the air supply of the air conditioner according to the state of the personnel (such as whether there are people, how many people, etc.) and the air quality of the air purification region.

[0069] For example, the state of the personnel in each air purification region can be obtained first. The personnel state can be obtained by manual input by the user, or by infrared detection (the infrared detector can be arranged at a position around the air conditioner, and the infrared detector can be driven to rotate to expand the detection range) and image recognition (the camera can be arranged at a position around the air conditioner, and the personnel state can be recognized by image comparison). Secondly, the air conditioner is controlled to supply air to the air purification region according to the state of the personnel in each air purification region and the air quality of each air purification region. Specifically, the air conditioner can be controlled to supply air to the air purification region in the following order: there are people and the air quality is from low to high, there are no people and the air quality is from low to high. Through such a control mode of the air conditioner, the air quality can be improved in a targeted manner, the air purification region where people exist is purified first to meet the actual personnel demand, and then the air purification region where no one exists is purified, so that better air purification effect can be obtained. And because it is not a non-targeted air supply to the entire space, energy saving effect can be achieved.

[0070] In addition to the example listed in the previous paragraph, the air conditioner can be controlled in other ways. For example, the number of people in each area to be purified can be obtained. The number of people can be obtained manually by the user or by image recognition (a camera can be placed on or around the air conditioner to recognize and determine by image comparison). Second, the air conditioner is controlled to supply air to the area to be purified in the following order: the number of people is not zero, the number of people is the most, the number of people is zero, and the air quality is the lowest. The air quality is the highest, and the intensity of the air supply is related to the air quality of the corresponding area: the lower the air quality, the higher the wind speed. Through such a control method of the air conditioner, the air quality can be improved in a targeted manner, and the area with the most people to be purified is processed first, providing another way to control the air conditioner different from the example in the previous paragraph.

[0071] In this step, the air in the area after the current purification treatment can be purified in the order set by the system. The air quality in the area after the current purification treatment can also be purified in the order set by the system based on the volume and air quality of each area to be purified. For example, each area to be purified can be purified by 50% in the order set by the system, and then each area to be purified can be purified in the order set by the system.

[0072] The step of "starting the air purification unit" further comprises:

[0073] Starting the air purification unit for a certain period of time t1;

[0074] Detecting the quality of the air by the air quality sensor;

[0075] If the quality of the air meets the standard, the air purification unit is turned off;

[0076] If the quality of the air does not meet the standard, the air purification unit is kept in the starting state for a certain period of time t2;

[0077] Re-executing the step of "detecting the quality of the air by the air quality sensor".

[0078] The values of t1 and t2 can be the same or different.

[0079] To sum up, the control method of the air conditioner can obtain air quality of different areas of the same air space to be adjusted, and air is supplied to the corresponding area according to the air quality, and the air is purified by the air purification part. In addition, air quality sensors do not need to be arranged in different areas, and only need to be arranged at the air inlet of the air conditioner, so that the cost can be reduced. The application can also specifically process different areas according to the personnel distribution and air quality of different areas. In addition, the air conditioner can also achieve accurate air supply for different areas according to the position parameter of the air deflector, and can also achieve the effect of energy saving.

[0080] It should be noted that the above embodiments are only used to illustrate the principles of the application, and are not used to limit the protection scope of the application. Those skilled in the art can adjust the above structure so that the application can be applied to more specific application scenarios without deviating from the principles of the application. These do not deviate from the principles of the application, and therefore fall within the protection scope of the application.

[0081] In addition, the application also provides an air conditioner which is arranged to execute the control method of the air conditioner described in any of the above embodiments.
