[0002] When the outside temperature is too high or too low, turning on the air conditioner can make the indoor temperature reach a comfortable temperature and improve the user experience. However, if the air outlet of the air conditioner blows the air directly towards the human body, it will cause discomfort to the human body.

[0003] Current air conditioners prevent direct airflow by sensing the user's location and controlling the air supply distance to be smaller than the distance between the air outlet and the user.

[0073] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without making creative efforts are within the scope of protection of this application.

Thus, features defined as "first" and "second" may explicitly or implicitly include one or more of the features.

In the following description, details are listed for the purpose of explanation. It should be understood that one of ordinary skill in the art will recognize that the present application can be implemented without using these specific details. In other examples, well-known processes will not be elaborated in detail to avoid obscuring the description of the embodiments of the present application with unnecessary details. Therefore, the present application is not intended to be limited to the embodiments shown, but is consistent with the widest range of principles and features disclosed in accordance with the embodiments of the present application.

[0076] Embodiments of the present application provide an air outlet control method, device, storage medium, and air conditioning system for an air conditioning system.

[0077] It should be noted that the air-conditioning system air outlet control system and the scenario described in the embodiment of the present application are intended to more clearly illustrate the technical solution of the embodiment of the present application, and do not constitute a limitation on the technical solution provided in the embodiment of the present application. Ordinary technicians in this field can know that with the evolution of the air-conditioning system air outlet control system and the emergence of new business scenarios, the technical solution provided in the embodiment of the present invention is also applicable to similar technical problems.

[0078] Next, we will introduce the air outlet control method for an air conditioning system provided in an embodiment of the present application. The execution entity of the air outlet control method for an air conditioning system provided in an embodiment of the present application can be an air outlet control device for an air conditioning system provided in an embodiment of the present application, or an air conditioning system. Below, we will use the air conditioning system as an example execution entity for explanation. It should be noted that the use of the air conditioning system as an example execution entity is merely for ease of understanding and does not constitute a limitation of the present application. For simplicity and ease of description, this execution entity will be omitted in the subsequent method embodiments.

[0079] Reference Figure 1 , Figure 1 This is a flow chart of an air-conditioning system air outlet control method provided in an embodiment of the present application. It should be noted that although the flow chart shows a logical order, in some cases, the steps shown or described may be performed in a different order than shown here. The air-conditioning system air outlet control method includes steps 101 to 103, wherein:

[0080] 101. Obtain an installation location of an air conditioning system and obtain a current air supply distance of the air conditioning system.

[0081] The installation location is the installation location of the indoor unit or the air outlet in the air conditioning system. For example, the installation location may include the two-dimensional coordinates of the indoor unit or the air outlet in the room. Figure 2 Take this as an example to illustrate.

[0082] refer to Figure 2 , Figure 2 This is a top view of the room where the air outlet of the air conditioning system is located. From the top view, the room is a rectangle with a length of l and a width of w, where the four sides of the rectangle are the walls of the room. Figure 2 The lower left corner of the room is taken as the zero point, the length of the room is taken as the positive direction of the x-axis, and the width of the room is taken as the positive direction of the y-axis. A two-dimensional coordinate system xoy is established with the above zero point, x-axis and y-axis. The installation position of the air conditioning system can be (x i ,y i ),Right now Figure 2 Point A in the i <l,y i <w。

[0083] In some embodiments, the installation location may also include the three-dimensional coordinates of the indoor unit or the air outlet in the room. Specifically, the direction perpendicular to the bottom surface of the room and toward the ceiling can be taken as the z-axis, and a three-dimensional coordinate system xyz can be established with the zero point, x-axis, y-axis, and z-axis in the above two-dimensional coordinate xoy. The installation location of the air conditioning system can be (x i ,y i , z i ), where x i <l,y i <w,z i <Height of the room h.

[0084] Furthermore, the installation location of the air conditioning system can be obtained based on information acquired by radar, TOF three-dimensional imaging components, and other devices installed in the air conditioning system. The installation location can be pre-acquired during installation of the air conditioning system and stored in the air conditioning system's storage space or cloud server. During air flow control, the installation location is retrieved from the storage space or cloud server. Furthermore, this information can be retrieved each time air flow control is implemented to prevent the user from changing the location of the indoor unit or air outlet in the air conditioning system according to their needs after the initial installation, which could result in an inaccurate pre-acquired installation location.

[0085] The current air supply distance may be the maximum distance that the air can reach in the current air supply direction of the air conditioning system when operating at the current operating parameters. For example, the current air supply distance may be the maximum air supply distance associated with the air supply mode set by the user. For example, for air conditioning system A, the maximum air supply distances corresponding to the low-speed air supply mode, the medium-speed air supply mode, and the high-speed air supply mode are 4 meters, 5 meters, and 6 meters, respectively. If the user sets the air supply mode of the current air conditioning system to the low-speed air supply mode, the current air supply distance is 4 meters. If the user changes the low-speed air supply mode to the high-speed air supply mode, the current air supply distance is changed from 4 meters to 6 meters.

[0086] In some embodiments, the current air supply distance may also be the maximum distance that the wind can reach when the current air supply direction is mapped to the floor of the room and the current operating parameters are used. Figure 3 To explain, Figure 3is the left view of the room. From the left view perspective, the room is a rectangle with a length of l and a height of h. A is the installation location of the air conditioning system in the room. a is a ray starting from A and not parallel to the ground, representing the current air supply direction of A. Obtain the mapping ray b of a on the bottom surface. The direction pointed by b is the direction of the current air supply direction mapped on the room floor. Assuming that the angle between a and the ground is 60°, for the air conditioning system in the low-speed air supply mode in the above example, the current air supply distance is 2 meters. For the medium-speed air supply mode and the high-speed air supply mode, the current air supply distance is 2.5 meters and 3 meters, respectively. If the user changes the low-speed air supply mode to the high-speed air supply mode, the current air supply distance changes from 2 meters to 3 meters.

[0087] For the sake of convenience in the following description, the air supply length and air supply distance described are understood to be the length and distance of the current air supply direction in the direction mapped on the floor of the room. Taking the current air supply distance as an example, the current air supply distance described should be understood as the current air supply direction in the direction mapped on the floor of the room, and the farthest distance that the wind can reach when operating with the current operating parameters.

[0088] 102. Determine whether a current air supply distance of the air conditioning system reaches a target air supply distance determined according to the installation position.

[0089] The target air supply distance is the air supply length of the air conditioning system when achieving full-area air supply. For example, the maximum length of the room can be used as the target air supply distance. For example, if the room is rectangular, the diagonal length of the room can be used as the target air supply distance. For another example, if the room is circular, the diameter of the room can be used as the target air supply distance. The advantage of using the maximum length of the room as the target air supply distance is that the air conditioning system can achieve full-room air supply when delivering air in any direction.

[0090] In some embodiments, the target air supply distance can also be determined based on room dimensions, thereby achieving the desired air supply distance for the entire target sub-area of ​​the room. For example, the maximum distance between the target sub-area and the installation location of the air conditioning system can be determined based on the installation location, and the maximum distance can be used as the target air supply distance to achieve the desired air supply distance for the target sub-area.

[0091] Furthermore, the target sub-area for air supply can be determined based on the distance between the user and the installation location. For example, the air conditioning system can simultaneously detect the user's location using a detection component, then determine the smallest rectangle encompassing both the user and the installation location, and use this rectangle as the target sub-area for air supply.

[0092] In summary, the air conditioning system can flexibly adjust the target air supply distance according to demand to achieve air supply to the entire room or part of the room.

[0093] The purpose of determining whether the current air supply distance reaches the target air supply distance is to determine whether the air conditioning system, when operating with the current parameters, can deliver air to the entire target air supply area. For example, to determine whether air can be delivered to the entire room, it is necessary to determine whether the current air supply distance can reach the target air supply distance for achieving full room air supply. To determine whether full area air supply within the target sub-area can be achieved, it is necessary to determine whether the current air supply distance can reach the target air supply distance for achieving full area air supply within the target sub-area.

[0094] 103. If the current air supply distance of the air conditioning system reaches the target air supply distance, adjust the angle of the air guide plate in the air conditioning system so that the current air supply height of the air conditioning system is greater than the preset human body height.

[0095] The preset human height may be a preset height obtained based on network data statistics. For example, the preset human height may be the world's average height obtained from the network. In addition, to prevent taller users from being blown directly by the wind, the preset human height may be set to the world's highest height obtained from the network.

[0096] Among them, the current air supply height is the height between the air blown out by the air conditioning system and the floor of the room. For example, the current air supply height can be the air supply height corresponding to the angle of the air guide plate. Before leaving the factory, the relationship between the angle of the air guide plate and the current air supply height has been pre-set in the storage space or cloud of the air conditioning system, so the current air supply height can be changed by adjusting the angle of the air guide plate. For example, if you want to change the current air supply height from 1.5 meters to 1.9 meters, you can query the relationship between the angle and the current air supply height in the storage space or cloud, obtain the air guide plate angle corresponding to 1.9 meters, and assume that it is 45° to the floor, then adjust the air guide plate to the corresponding angle to change the current air supply height.

[0097] Among them, when the current air supply distance reaches the target air supply distance, it means that the air-conditioning system can deliver air to the entire room or the target sub-area in the room. At this time, the angle of the air guide plate can be adjusted to make the current air supply height greater than the preset human height to achieve the function of preventing direct blowing.

[0098] It should be noted that the step of adjusting the angle of the air deflector can also be performed at any position of the solution provided in the embodiment of the present application. For example, while obtaining the installation position of the air conditioner, the angle of the air deflector can be adjusted so that the current air supply height is greater than the preset human height.

[0099] In summary, the embodiment of the present application obtains the installation location of the air conditioning system and the current air supply distance of the air conditioning system; determines whether the current air supply distance of the air conditioning system reaches the target air supply distance determined based on the installation location; if the current air supply distance of the air conditioning system reaches the target air supply distance, adjusts the angle of the air guide plate in the air conditioning system so that the current air supply height of the air conditioning system is greater than the preset human height. It can be seen that after determining that the current air supply distance has reached the target air supply distance that can achieve full-area air supply, the angle of the air guide plate is adjusted to change the current air supply height so that the current air supply height is greater than the preset human height, thereby preventing the air blown by the air conditioning system from directly blowing on the human body, thereby achieving both direct blowing protection and full-area air supply.

[0100] In order to accurately and efficiently obtain the current air supply distance, the current air supply distance of the air conditioning system can be determined based on the speed of the outdoor fan. Figure 4 At this time, the obtaining of the current air supply distance of the air conditioning system may specifically include:

[0101] 201. Obtain a current rotation speed of an outdoor fan in the air-conditioning system.

[0102] 202. Query a speed-air supply distance mapping relationship to obtain a current air supply distance corresponding to the outdoor fan operating at the current speed.

[0103] The speed-to-air-distance mapping is pre-set in the air conditioning system's storage space or in the cloud, with a one-to-one mapping of air supply distances for each speed. For example, the speed-to-air-distance mapping can be a speed-to-air-distance curve, and the current air supply distance can be obtained by querying the speed-to-air-distance curve. For example, if the current speed of the outdoor fan is 1000 rpm, and the speed-to-air-distance curve is queried to determine the corresponding air supply distance of 1000 rpm as 3 meters, then the current air supply distance is 3 meters.

[0104] Therefore, through the preset speed-air supply distance mapping relationship, the accurate current air supply distance can be obtained by simply querying after obtaining the current speed of the outdoor fan, which is efficient and simple and does not require additional detection steps.

[0105] In order to avoid excessive air supply from the air conditioning system due to the target air supply distance being too long, the target air supply distance can be determined based on the installation location and the air supply range of the air conditioning system. Figure 5 At this time, the determining whether the current air supply distance reaches the target air supply distance determined according to the installation position may further specifically include:

[0106] 301. Obtain a current air supply range preset in the air-conditioning system.

[0107] The current air supply range refers to the room area to which the air conditioning system supplies air. For example, the current air supply range can be one of the sub-room areas to which the air is supplied after the room is pre-divided into several sub-room areas. Figure 6 For explanation, refer to Figure 6 During installation, the air conditioning system first divides the room X where it is installed into three sub-rooms, X1, X2, and X3, according to preset rules. If the air conditioning system only supplies air to X1, then X1 is the current air supply range. If the air conditioning system supplies air to both X1 and X2, then both X1 and X2 are the current air supply ranges.

[0108] In some embodiments, the current air supply range can also be part of the sub-room area. Figure 6 The current air supply range can also be a part of X1, X2 or X3, that is, the black area in the figure.

[0109] Furthermore, each sub-room area can have a corresponding left and right air deflector angle. The left and right air deflector angles can be the angles between the left and right air deflectors and the main beam of the room. Assuming the left and right air deflector angles can only be changed to 0°, 30°, and 60°, at 0°, the air conditioner only supplies air to sub-room area X1; at 30°, the air conditioner only supplies air to sub-room area X2; and at 60°, the air conditioner only supplies air to sub-room area X3. Therefore, the air conditioning system can also determine the current air supply range based on the left and right air deflector angles.

[0110] 302. Obtain a point that is farthest from the installation position within a current air supply range preset in the air conditioning system.

[0111] Continue with Figure 6 For illustration, A in the figure is the installation location of the air conditioning system. If the current air supply range is X2, the point in X2 that is farthest from A is obtained, for example, B. Therefore, the farthest point is B.

[0112] 303. Determine the distance between the farthest distance point and the installation position as the target air supply distance.

[0113] Continue with Figure 6 To illustrate, if B is the point in the room that is farthest from the installation location, the length of line segment AB can be used as the target air supply distance.

[0114] To prevent the actual air supply distance from failing to reach the theoretical air supply distance due to an aging air conditioning system, a length greater than the length of AB can be used as the target air supply distance. For example, the length of AB can be multiplied by a coefficient greater than 1, and the resulting value can be used as the target air supply distance. This ensures that even if the actual air supply distance does not reach the theoretical air supply distance, air can still be supplied to the entire area.

[0115] Furthermore, a mapping relationship can be formed between the target air supply distance and the corresponding current air supply range and recorded in the storage space of the air-conditioning system or in the cloud. The next time the same current air supply range is detected, the step of obtaining the target air supply distance can be omitted, and the target air supply distance can be obtained by simply querying the recorded mapping relationship.

[0116] In summary, updating the target air supply distance with the distance between the farthest distance point and the installation location can avoid excessive air supply and energy waste.

[0117] For different activity states of people in the room, such as sitting still or exercising, the air supply mode that prevents direct blowing can be determined based on the frequency of human activity in the room. Figure 7 At this time, the determination of whether the current air supply distance reaches the target air supply distance determined according to the installation position may specifically include:

[0118] 401. Divide the room where the air-conditioning system is located into multiple room areas.

[0119] The room in which the air conditioning system is located refers to the room in which the air outlet or indoor unit of the air conditioning system is located. The room can be divided according to different principles. For example, the room can be divided into several room areas of equal area. For example, for a rectangular room, the diagonal lines of the rectangle can be used as dividing lines to divide the room into four room areas of equal area. The method of dividing the room by area can easily obtain multiple room areas. After the room is divided into multiple room areas, the air conditioning system can change the air supply area by changing the angles of the left and right air guide plates. For details, please refer to the description in step 301 and will not be repeated here.

[0120] In some embodiments, a room can be divided into several functional areas based on the placement of furniture. For example, the area containing the bed can be divided into a sleeping area, the area containing a desk and bookcase can be divided into a study area, and the area containing a large area of ​​flooring can be divided into a recreational or exercise area. This method of dividing a room based on furniture placement can generate multiple functional areas, allowing for more targeted treatment of each area. For example, when intelligently adjusting the air volume of an air conditioning system, the final adjusted air volume can be determined based on the function of the air supply area. For areas used for recreation or exercise, the air volume can be appropriately increased to improve the cooling effect. For areas used for sleeping or studying, the air volume can be appropriately reduced to prevent the person from being irritated by excessive amounts of cold air while at rest. Alternatively, the function of the air supply area can be used to determine whether to adjust the air outlet mode to prevent direct airflow. For example, if the air supply area contains a bed, the air outlet mode can be adjusted to prevent direct airflow, as direct airflow can cause discomfort when sleeping. When the air supply area includes a large area of ​​floor, people usually do a lot of exercise in this area, so the air outlet mode can be adjusted to the non-direct blowing prevention mode.

[0121] By dividing the room into areas, you can classify the areas in the room, which will help you determine whether the air outlet mode needs to be adjusted.

[0122] Furthermore, the division results can be stored in the storage space of the air conditioning system or in a cloud server. When the user turns on the air conditioning system next time, the air conditioning system can directly call the division results in the storage space or cloud server, reducing the calculation process.

[0123] 402. Count the frequency of human activities in each of the room areas, and obtain the sum of the frequencies of human activities in all the room areas.

[0124] The human activity frequency can be the number of times a human body is detected within a fixed time period. For example, the air conditioning system can perform a human body detection on each room area at a fixed time interval within a fixed time period, and the human activity frequency is the number of times a human body is detected within a fixed time period. Figure 6 For illustration, assume that the fixed time is 1 minute and the time interval is 30 seconds. At the 0th second, the air conditioning system Figure 6 If a human body appears in X1, the human activity frequency count of X1 will be increased by 1 and recorded as 1. The human activity frequencies of X2 and X3 will not be changed. At the 30th second, the air conditioning system Figure 6The air conditioning system performs a second check on the room. If a person is present in both X1 and X2, the human activity frequency of X1 is incremented by 1 again, becoming 2, while the human activity frequency of X2 is incremented by 1 again, becoming 1. At the 60th second, the air conditioning system performs a third check. If no person is present in the room, the human activity frequencies of X1, X2, and X3 remain unchanged. Therefore, in this example, the human activity frequency of X1 is 2, the human activity frequency of X2 is 1, and the human activity frequency of X3 is 0.

[0125] Among them, the sum of the frequencies of human activities in all the room areas refers to the value obtained by adding the frequencies of human activities in each room area. Continuing with the example in this step, the frequency sum is the value 3 obtained by adding the frequencies of human activities of X1, X2 and X3.

[0126] Furthermore, the method for detecting human bodies can be to use optical flow to identify whether there is a human motion track in the room. If there is a human motion track in the room, the presence of a human body is determined, and the human body position in the room is determined using a human body position detection model. Specifically, the human body position detection model can be obtained by training an image recognition model with a large number of images containing human bodies.

[0127] After obtaining the position of the human body in the room, the area of ​​the room where the human body is located can be determined based on the position, and the frequency of human activities can be counted.

[0128] In addition, the position of the human body in the room can be identified based on the channel status information obtained by the WIFI module installed in the air-conditioning system, and then the area of ​​the room where the human body is located can be determined based on the position, and the frequency of human activities can be counted.

[0129] 403. If the quotient of the human activity frequency and the sum of the frequencies in the current air supply area is less than the preset sitting frequency, update the target air supply distance according to the installation position.

[0130] The current air supply area may be one of the multiple room areas divided in advance. Figure 6 For example, when the air conditioning system is delivering air to X1, X1 is the current air supply area, and the human activity frequency in the current air supply area is the human activity frequency of X1. Some air conditioning systems can deliver air to multiple areas simultaneously. For example, the air conditioning system can deliver air to X1 and X2 simultaneously. In this case, the current air supply area includes both X1 and X2, so the human activity frequency in the current air supply area is the human activity frequency of X1 plus the human activity frequency of X2.

[0131] The preset sitting frequency refers to the value reached by the quotient of the human activity frequency in the current air supply area and the sum of the frequencies when a person is in a sitting state. Exemplarily, the preset sitting frequency can be a value calculated by the air conditioning system after pre-collecting the human activity frequencies in multiple rooms. For example, the air conditioning system can first obtain the human activity frequencies in multiple rooms through the data in the cloud server or the data stored in the storage space, and then filter out the data with human activity frequencies less than a preset threshold from all the data, and finally calculate the average value of the quotient of the human activity frequency in the current air supply area and the sum of the frequencies when a person is in a sitting state based on the filtered data, and use this average value as the preset sitting frequency. The preset threshold can be a value derived from experience. When the human activity frequency is greater than the preset threshold, it indicates that the person is in motion. When the human activity frequency is less than the preset threshold, it indicates that the person is in a sitting state.

[0132] If the quotient of the human activity frequency and the sum of the frequencies in the current air supply area is less than the preset sitting frequency, it means that the person is in a sitting state. Therefore, the air-conditioning system needs to adjust the current air supply height to be higher than the preset human height to adjust the air supply mode to the anti-direct blowing mode.

[0133] If the quotient of the human activity frequency and the sum of the frequencies in the current air supply area is greater than the preset sitting frequency, it means that the person is in motion. Therefore, the air conditioning system does not need to be adjusted to the anti-direct blowing air supply mode, and the current air supply height does not need to be adjusted.

[0134] It should be noted that in the air-conditioning system, steps 301-303 can be combined with steps 401-403. Before performing steps 301-303, steps 401-403 are first performed to determine whether direct blowing protection is required. If direct blowing protection is required, steps 301-303 are performed, and the distance between the farthest distance point and the installation position is updated to the target air supply distance.

[0135] For some air conditioning systems, the sweeping angle of the sweeping blades can be intelligently adjusted according to the installation location to prevent the wind from blowing towards the wall and wasting cooling energy. Figure 8 At this time, the steps of obtaining the installation location of the air conditioning system and obtaining the current air supply distance of the air conditioning system may specifically include:

[0136] 501. Obtain the wall position of each wall in the room where the air conditioning system is located.

[0137] The wall positions may be the coordinates of the midpoints of all walls in the xoy two-dimensional coordinate system in step 101. Figure 2 For example, Figure 2 The midpoint coordinates of wall 1 are (0.5*l, 0), so the wall position of wall 1 is (0.5*l, 0).

[0138] In some embodiments, the wall position may also be the coordinates of the midpoints of all walls in the xyz three-dimensional coordinate system in step 101 .

[0139] It should be noted that the coordinates of the midpoint are used as the wall position in this step only for the convenience of explanation. In actual application, the coordinates of any point on the wall can be used as the wall position, or the coordinate set of multiple points on the wall can be used as the wall position, etc.

[0140] 502. Obtain a vertical distance between the wall position and the installation position.

[0141] The vertical distance refers to the minimum distance between the wall position and the installation position. Continuing with the example in step 501, if the wall position of wall 1 is the midpoint coordinate of wall 1 (0.5*1, 0), then the vertical distance between the wall position of wall 1 and the installation position is the distance between the coordinate (0.5*1, 0) and the coordinate (x i ,y i ) between them.

[0142] If the wall position of wall 1 is the coordinate set of all coordinates on wall 1, then the vertical distance refers to the installation position (x i ,y i ) on the wall 1 (x i ,0) and (x i ,y i ) between them.

[0143] 503. Determine whether the vertical distance is less than a preset energy-saving distance.

[0144] 504. If the vertical distance is less than a preset energy-saving distance, adjust the sweeping angle of the sweeping blades in the air-conditioning system to a preset energy-saving angle.

[0145] Among them, the preset energy-saving distance is used to indicate whether the wall is too close to the installation location. If the vertical distance is less than the preset energy-saving distance, it means that the indoor unit or air outlet of the air-conditioning system is too close to the wall. If the air blown out by the air-conditioning system blows towards the wall, it will cause waste of cooling energy.

[0146] The energy-saving angle can be one of multiple sweep angles preset by the air conditioning system. For example, the energy-saving angle can be the sweep angle that, after the air conditioning system has iterated through all preset sweep angles, results in the air conditioning system being able to place the target wall outside the current air supply range of the air conditioning system. For example, when the air conditioning system detects that the target wall is within the current air supply range of the air conditioning system, the air conditioning system can control the sweep blades to gradually increase the sweep angle until the maximum sweep angle is reached. During this process, if it is detected that the target wall is outside the current air supply range of the air conditioning system when operating at a certain sweep angle, air will be discharged at that sweep angle, and adjustment of the sweep blades' sweep angle will cease.

[0147] Furthermore, detection components such as infrared detectors and TOF sensors installed on the air conditioning system can be used to detect whether the target wall is within the current air supply range, and the details will not be repeated here.

[0148] In some embodiments, the energy-saving angle may also be the sweep angle that minimizes the output power of the air conditioning system after the air conditioning system has traversed all preset sweep angles. For the same set room temperature, if the air from the air conditioning system blows onto the wall, resulting in a waste of cooling energy, the output power of the air conditioning system will be increased. For example, when the air conditioning system uses a 30° sweep angle, the wind will blow onto the wall, while when the air conditioning system uses a 60° sweep angle, the wind will not blow onto the wall. For the same set room temperature, the output power of the air conditioning system may be different when the air conditioning system uses 30° and 60°. A lower output power indicates that the wind will not blow onto the wall when the current sweep angle is used, and therefore the current sweep angle is the energy-saving angle.

[0149] For some air conditioning systems, the current speed of the outdoor fan can be adjusted according to the distance between the return air outlet and the ceiling to avoid surge. Figure 9 At this time, the steps of obtaining the installation location of the air conditioning system and obtaining the current air supply distance of the air conditioning system may specifically include:

[0150] 601. According to an installation position of a return air outlet in the air-conditioning system, obtain a return air outlet distance between the return air outlet and a ceiling of a room where the return air outlet is located.

[0151] The return air outlet distance between the return air outlet and the ceiling of the room where the return air outlet is located may refer to the minimum distance between the return air outlet and the ceiling. For example, the return air outlet distance may be the straight-line distance between the orthographic projection point of the return air outlet on the ceiling and the return air outlet.

[0152] The reason for obtaining the return air outlet distance is that it can be used to represent the distance between the return air outlet and the outlet. If the return air outlet distance is too small, it means that the return air outlet and the outlet are too close. The return air outlet may affect the airflow condition of the outlet, such as blocking the outlet, and ultimately cause surge.

[0153] 602. If the return air outlet distance is less than the surge distance, adjust the current speed of the outdoor fan in the air-conditioning system to a non-surge speed corresponding to the return air outlet distance.

[0154] The surge distance refers to the distance between the return air outlet and the ceiling that may cause surge. For example, the surge distance can be determined based on parameters obtained in pre-production testing. For example, if, in pre-production testing, the air conditioning system experiences surge when the return air outlet distance is less than or equal to 120 mm, the surge distance can be set to 120 mm.

[0155] In some embodiments, in order to enable the solution in the embodiments of the present application to be applied to air-conditioning systems with various installation layouts, the surge distance can also be determined based on the installation position of the air outlet. For example, the distance between the air outlet and the ceiling can be multiplied by a coefficient greater than 1, and the result can be used as the surge distance. For example, when the distance between the air outlet and the ceiling is 200 mm, 200 mm can be multiplied by 1.5 to get 300 mm, and then 300 mm can be used as the surge distance. It should be noted that the larger the coefficient, the higher the possibility that a misjudgment will cause a surge, but the possibility of an actual surge is lower; and the smaller the coefficient, the lower the possibility of a misjudgment, but the possibility of a surge is higher, so the coefficient can be adjusted according to the actual needs of the scenario.

[0156] The "no-surge speed" is the outdoor fan speed determined based on the return air outlet distance. When the outdoor fan operates at the no-surge speed, the air conditioning system will not surge even if the return air outlet distance is less than the surge distance. For example, before the air conditioning system leaves the factory, multiple return air outlet distances and the no-surge speed corresponding to each return air outlet distance can be obtained through testing. A distance-speed mapping relationship can be constructed and stored in the air conditioning system's storage space. Then, when it is detected that the return air outlet distance is less than the surge distance, the speed corresponding to the return air outlet distance in the distance-speed mapping relationship is obtained and used as the no-surge speed. For example, if the return air outlet distance is 100 mm and the surge distance is 120 mm, the air conditioning system determines that the return air outlet distance is less than the surge distance. The air conditioning system then queries the distance-speed mapping relationship to obtain the speed corresponding to 100 mm, which is 500 rpm. After obtaining the speed, 500 rpm can be used as the no-surge speed.

[0157] Furthermore, the no-surge speed can also be the speed corresponding to the distance range of the return air outlet. For example, multiple distance ranges can be pre-acquired, and a speed set for each distance range. When the outdoor fan operates at a specific speed, the air conditioning system will not surge as long as the return air outlet distance is within the distance range corresponding to the specific speed. For example, three distance ranges can be pre-acquired: 20 mm-40 mm, 41 mm-60 mm, and 61 mm-80 mm. Testing has shown that when the outdoor fan operates at a speed of 300 rpm, the air conditioning system will not surge when the return air outlet distance is within the distance range of 20 mm-40 mm. Therefore, 300 rpm can be used as the speed corresponding to this distance range. Similarly, corresponding speeds can be obtained for the distance ranges of 41 mm-60 mm and 61 mm-80 mm. When the air conditioning system detects that the return air outlet distance is less than the surge distance, the speed corresponding to the return air outlet distance range can be obtained as the no-surge speed.

[0158] When the current air supply distance of the air conditioning system does not reach the target air supply distance, it is necessary to adjust the current air supply distance of the air conditioning system to achieve air supply in the entire area. Figure 10 At this time, the determining whether the current air supply distance of the air conditioning system reaches the target air supply distance determined according to the installation position may specifically include:

[0159] 701. If the current air supply distance of the air conditioning system does not reach the target air supply distance, increase the current speed of the outdoor fan in the air conditioning system to a preset speed.

[0160] The preset speed is the speed corresponding to the target air supply distance. When the outdoor fan operates at the preset speed, the current air supply distance of the air conditioning system can reach the target air supply distance. For example, the speed corresponding to the target air supply distance can be obtained based on the speed-air supply distance curve, and then the current speed of the outdoor fan can be adjusted to the speed corresponding to the target air supply distance. For example, if the target air supply distance is 4 meters, the speed-air supply distance curve is queried to obtain a speed of 1000 rpm corresponding to 4 meters. Therefore, the preset speed is 1000 rpm, and the current speed of the outdoor fan can be increased to 1000 rpm.

[0161] Furthermore, to prevent the actual air supply distance from failing to reach the air supply distance corresponding to the speed in the speed-air supply distance curve, the speed corresponding to the target air supply distance in the speed-air supply distance curve can be multiplied by a coefficient greater than 1, and the resulting speed can be used as the preset speed. For example, if the target air supply distance is 4 meters, and the speed-air supply distance curve is queried to obtain a speed of 1000 rpm corresponding to 4 meters, to prevent the actual air supply distance of the air conditioning system from failing to reach 4 meters when the outdoor fan is operating at 1000 rpm, 1000 rpm can be multiplied by 1.5, and the resulting speed of 1500 rpm can be used as the preset speed.

[0162] 702. When the current speed of the outdoor fan reaches the preset speed, adjust the angle of the air guide plate in the air-conditioning system so that the current air supply height of the air-conditioning system is greater than the preset human body height.

[0163] When the current speed of the outdoor fan reaches the preset speed, it means that the current air supply distance of the air-conditioning system has reached the target air supply distance, and full-area air supply has been achieved. At this time, the angle of the air guide plate can be adjusted to change the current air supply height of the air-conditioning system to achieve the function of preventing direct blowing.

[0164] In order to better implement the air outlet control method of the air conditioning system in the embodiment of the present application, based on the air outlet control method of the air conditioning system, the embodiment of the present application also provides an air outlet control device for the air conditioning system, such as Figure 11 FIG. 1 is a schematic structural diagram of an embodiment of an air outlet control device for an air conditioning system according to an embodiment of the present application.

[0186] If the return air outlet distance is less than the surge distance, the current speed of the outdoor fan in the air-conditioning system is adjusted to a non-surge speed corresponding to the return air outlet distance.

[0187] In a possible implementation, the adjusting unit 1103 may also be configured to:
