[0029] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0030] In the subsequent description, the suffixes such as "module", "component" or "unit" used to represent elements are only used to facilitate the description of the present application and have no specific meaning. Therefore, "module" and "component" can be used interchangeably.

[0031] In order to solve the problems mentioned in the background technology, according to one aspect of the embodiments of the present application, an embodiment of an air outlet control method of an air conditioning unit is provided, such as Figure 1 As shown, the method may include the following steps:

[0032] Step S102, when it is detected that a user appears in the indoor space where the air conditioning unit is located, determining a target position of the user in the indoor space;

[0033] Step S104, determining an air outlet strategy according to the sub-area where the target location is located and the current working mode of the air conditioning unit;

[0034] Step S106, controlling the air outlet of the air conditioning unit according to the air outlet strategy.

[0035] Through the above steps S102 to S106, the present application divides the indoor space where the air conditioner is located into zones, and determines the corresponding air outlet strategy according to the sub-zone where the user is located to control the air outlet of the air-conditioning unit, and performs intelligent on-demand air supply for different user locations, thereby improving the comfort of the air supply of the air-conditioning unit and solving the technical problem that ordinary duct air conditioners cannot supply air intelligently.

[0036] In step S102, infrared sensors, millimeter wave radars, laser radars, and camera devices can be used to identify whether a user has entered the indoor space where the air conditioning unit is located. Infrared sensors detect users in the indoor space by sensing infrared radiation emitted by objects. Since the human body emits a certain amount of infrared radiation, the infrared sensor can capture this radiation and determine whether a user exists. Millimeter wave radar uses the characteristics of millimeter waves for detection. It can emit millimeter waves and receive the signals reflected back. By analyzing these signals, the presence and position of users in the indoor space can be detected. Millimeter wave radars have excellent detection accuracy and anti-interference capabilities and are suitable for various complex environments. Laser radars detect targets by emitting laser beams and receiving reflected signals. Laser radars have high resolution and precise measurement capabilities, and can accurately obtain the location information of users in the indoor space. Camera devices detect the presence of users by capturing images of the indoor space. Camera devices can capture indoor scenes in real time and identify and track users through image recognition technology.

[0037] In an optional embodiment, before determining the air outlet strategy in step S104 according to the sub-area where the target position is located and the current working mode of the air conditioning unit, the method further includes dividing the indoor space into a plurality of sub-areas in the following manner:

[0038] Step 1, obtaining the recognition angle range of the position sensor on the air conditioning unit;

[0039] Step 2: dividing the identification angle range into a first angle range and a second angle range, wherein the first angle range is a range smaller than a preset angle threshold, and the second angle range is a range greater than or equal to the preset angle threshold;

[0040] Step 3: take the coverage area of ​​the first angle range in the indoor space as the first large area, and take the coverage area of ​​the second angle range in the indoor space as the second large area, wherein the first large area is a sub-area away from the side of the air-conditioning unit, and the second large area is a sub-area close to the side of the air-conditioning unit.

[0041] In the embodiment of the present application, it is first necessary to determine the specific recognition angle range of the position sensor on the air-conditioning unit. The position sensor is generally used to sense and determine the position of the user in the indoor space. Different sensors have different recognition angle ranges, which determine the spatial area in which the sensor can detect the user. Next, the recognition angle range of the position sensor is further divided. It can be based on a preset rule or according to actual needs. For example, the recognition angle range can be divided into two main parts: a first angle range and a second angle range. The projection area in which the position sensor can work can be divided according to the first angle range and the second angle range. This division of areas is based on a comprehensive consideration of user comfort and the working efficiency of the air-conditioning unit. By dividing the indoor space into two large areas away from the air-conditioning unit and close to the air-conditioning unit, the system can more accurately identify the user's position, so as to provide a suitable air supply strategy according to the user's location. Moreover, the air supply of the air-conditioning unit usually has a certain range and angle. By dividing the recognition angle range into a first angle range and a second angle range, and dividing the projection area according to these ranges, the degree of matching between the sub-area where the user is located and the air supply characteristics of the air-conditioning unit can be more accurately determined. In this way, the system can utilize the air supply capacity of the air-conditioning unit more efficiently and ensure the best air supply effect.

[0042] In the present application embodiment, Figure 2 and Figure 3 As shown, the air conditioning unit is installed on one side of the room wall. Taking the infrared sensor as an example, the area can be divided according to the recognition angle range of the infrared sensor, such as taking 45° downward as the boundary, less than 45° is Zone I (the first large area), and greater than 45° is Zone II (the second large area).

[0043] In step S104, the air outlet strategy is determined according to the sub-area where the target position is located and the current working mode of the air conditioning unit. In this application, the upper and lower air guide plates of the air outlet are closed by default at 0°, the air guide plate adjustment angle range is 30° to 90°, the left and right air guide plates are in the default middle position of 0°, the left is negative, the right is positive, the air guide plate adjustment angle range is -45° to 45°, the return air outlet defaults to 90° for the upper and lower air guide plates, and 0° for the left and right air guide plates.

[0044] In an optional embodiment, determining the air outlet strategy according to the sub-area where the target location is located and the current working mode of the air conditioning unit includes any of the following:

[0045] When the target position is in the first large area, and the current working mode of the air-conditioning unit is the wind avoidance mode, the first air outlet provided on the side of the air-conditioning unit is used as the actual return air outlet, the second air outlet provided on the bottom of the air-conditioning unit is used as the actual air outlet, the first preset angle is used as the air outlet angle of the upper and lower air guide plates at the second air outlet, and the second preset angle is used as the air outlet angle of the left and right air guide plates at the second air outlet for air supply;

[0046] When the target position is in the second large area and the current working mode of the air-conditioning unit is the wind-avoiding mode, the first air outlet is the actual air outlet, the second air outlet is the actual return air outlet, the first preset angle is the air outlet angle of the upper and lower air guide plates at the first air outlet, and the second preset angle is the air outlet angle of the left and right air guide plates at the first air outlet for air supply.

[0047] This application formulates a specific air outlet strategy based on the sub-area where the target location is located and the current working mode of the air-conditioning unit. When the target location is located in the first large area far away from the air-conditioning unit, the system uses specific air outlet and return air outlet configurations, as well as preset air guide plate angles, to ensure that the area can obtain sufficient air supply while avoiding the discomfort caused by direct blowing. When the target location is located in the second large area close to the air-conditioning unit, the system reduces the direct blowing feeling to the user and improves the user's comfort by changing the configuration of the air outlet and return air outlet, and adjusting the angle of the air guide plate. This air outlet strategy not only takes into account the user's comfort, but also fully considers the air supply efficiency. By selecting appropriate air outlet and return air outlet configurations according to the user's location and the working mode of the air-conditioning unit, and setting the appropriate air guide plate angle, the system can ensure that the air supply direction is accurate and the air supply intensity is moderate, thereby improving the air supply efficiency. This helps to reduce energy waste and achieve more energy-saving operation.

[0048] In the present application embodiment, Figure 4 As shown, for the wind avoidance mode, when it is detected that there is a user in zone I, the second air outlet is selected as the air outlet and the first air outlet is selected as the return air outlet. At this time, the angle of the upper and lower air guide plates of the second air outlet is 90° (first preset angle), and the left and right air guide plates are 0° (second preset angle). When the second air outlet is used as the air outlet and the angle of the upper and lower air guide plates of the second air outlet is 90°, the wind is sent vertically downward from the second air outlet, which can avoid blowing directly on the users in zone I and realize the wind avoidance mode. The left and right air guide plates are set to 0° in order to ensure that the room as a whole obtains uniform and sufficient air supply. The angle of the left and right air guide plates is in the range of -45° to 45°. When it is biased to -45°, the left area of ​​the air conditioner will obtain a larger air supply than the right area. When it is biased to 45°, the right area of ​​the air conditioner will obtain a larger air supply than the left area. This can also adjust the air guide angle according to the actual location of the user and the air supply mode (wind avoidance, wind with people).

[0049] In the present application embodiment, Figure 5 As shown, for the wind avoidance mode, when it is detected that there is a user in zone II, the first air outlet is selected as the air outlet and the second air outlet is selected as the return air outlet. At this time, the upper and lower air guide plates of the first air outlet are at an angle of 90°, and the left and right air guide plates are at 0°.

[0050] In an optional embodiment, when no user is detected in the first large area and the second large area, determining the air outlet strategy includes any of the following:

[0051] When the current working mode of the air-conditioning unit is the cooling mode, the first air outlet is used as the actual air outlet, the second air outlet is used as the actual return air outlet, the first preset angle range is used as the air outlet angle of the upper and lower air guide plates at the first air outlet, and the second preset angle range is used as the air outlet angle of the left and right air guide plates at the first air outlet for air supply;

[0052] When the current working mode of the air-conditioning unit is the heating mode, the second air outlet is the actual air outlet, the first air outlet is the actual return air outlet, the first preset angle range is the air outlet angle of the upper and lower air guide plates at the second air outlet, and the second preset angle range is the air outlet angle of the left and right air guide plates at the second air outlet for air supply.

[0053] In this application, if no user is detected in the first area and the second area, no matter what air supply mode the air conditioner is in at this time, it can supply air with the highest efficiency. For example, in cooling mode, since hot air is mostly concentrated in the upper roof area of ​​the room, the first air outlet is selected to directly deliver cold air to the hot air on the upper floor to cool it down. In heating mode, since cold air is mostly concentrated in the lower area of ​​the room, the second air outlet is selected to directly deliver hot air to the cold air on the lower floor to heat it up. In this way, the room can be cooled or heated efficiently to quickly meet user needs.

[0054] In an embodiment of the present application, when no user is detected in the first large area and the second large area, if the current working mode is the cooling mode, the first air outlet serves as the air outlet and the second air outlet serves as the return air outlet. The upper and lower air guide plates of the first air outlet are at an angle of 30° to 90° (first preset angle range) to sweep the air, and the left and right air guide plates are at a angle of -45° to 45° (second preset angle range) to sweep the air. The air guide range of the upper and lower air guide plates is 30° to 90°, and the air guide range of the left and right air guide plates is -45° to 45°. Therefore, when no user is detected in the first large area and the second large area, the air conditioner can supply air throughout the entire area to quickly heat up or cool down the room to meet user needs.

[0055] In the embodiment of the present application, if the current working mode is heating mode, the second air outlet is used as the air outlet, and the first air outlet is used as the return air outlet. The upper and lower air guide plates of the second air outlet are at an angle of 30° to 90° for sweeping air, and the left and right air guide plates are at an angle of -45° to 45° for sweeping air.

[0056] In an optional embodiment, dividing the indoor space into a plurality of sub-areas further comprises:

[0057] Divide the first large area into multiple sub-areas in order from left to right and from top to bottom;

[0058] The second large area is divided into a plurality of sub-areas in order from left to right and from top to bottom.

[0059] In the present application embodiment, Figure 6 As shown, in order to control the air outlet more accurately and to further improve the air supply comfort, Zone Ⅰ (the first large zone) and Zone Ⅱ (the second large zone) can be further divided into six small areas AF, a total of 12 small areas IA-IF and ⅡA-ⅡF.

[0062] When the target position is in any sub-area of ​​the second large area, and the current working mode of the air-conditioning unit is the wind-avoiding-people mode, the first air outlet is taken as the actual air outlet, the second air outlet is taken as the actual return air outlet, and according to the second preset corresponding relationship between the target sub-area of ​​the target position in the second large area and the angle of the air guide plate in the wind-avoiding-people mode, the third air outlet angle of the upper and lower air guide plates of the first air outlet and the fourth air outlet angle of the left and right air guide plates are determined;

[0063] When the target position is in any sub-area of ​​the first large area, and the current working mode of the air-conditioning unit is the wind-follows-people mode, the first air outlet is taken as the actual air outlet, the second air outlet is taken as the actual return air outlet, and according to the third preset correspondence between the target sub-area of ​​the target position in the first large area and the angle of the air guide plate in the wind-follows-people mode, the fifth air outlet angle of the upper and lower air guide plates of the first air outlet and the sixth air outlet angle of the left and right air guide plates are determined;

[0064] When the target position is in any sub-area of ​​the second large area, and the current working mode of the air-conditioning unit is the wind-follows-people mode, the first air outlet is taken as the actual return air outlet, the second air outlet is taken as the actual air outlet, and according to the fourth preset correspondence between the target sub-area of ​​the target position in the second large area and the angle of the air guide plate in the wind-follows-people mode, the seventh air outlet angle of the upper and lower air guide plates of the second air outlet and the eighth air outlet angle of the left and right air guide plates are determined;

[0065] When the target position appears in the first large area and the second large area at the same time, and the current working mode of the air-conditioning unit is the wind avoidance mode, the first air outlet is taken as the actual air outlet, the second air outlet is taken as the actual return air outlet, and the wind guide plate angle of the first air outlet is determined according to the target position in the first large area, including: determining the ninth wind outlet angle of the upper and lower wind guide plates and the tenth wind outlet angle of the left and right wind guide plates of the first air outlet according to the first preset corresponding relationship between the target sub-area of ​​the target position in the first large area and the wind guide plate angle in the wind avoidance mode;

[0066] When the target position appears in the first area and the second area at the same time, and the current working mode of the air-conditioning unit is the wind-follows-people mode, the second air outlet is taken as the actual air outlet, the first air outlet is taken as the actual return air outlet, and the angle of the air guide plate of the second air outlet is determined according to the target position in the second area, including: determining the eleventh air outlet angle of the upper and lower air guide plates and the twelfth air outlet angle of the left and right air guide plates of the second air outlet according to the fourth preset correspondence between the target sub-area of ​​the target position in the second area and the air guide plate angle in the wind-follows-people mode.

[0067] In the embodiment of the present application, if the current working mode of the air conditioning unit is the wind avoidance mode, then for the case where the target location is in the first large area and the second large area, the following can be used to first Figure 4 , Figure 5The air outlet and the return air outlet are determined in a manner, that is, when the target position is in any sub-area of ​​the first large area, and the current working mode of the air conditioning unit is the wind avoidance mode, the first air outlet is the actual return air outlet, and the second air outlet is the actual air outlet; when the target position is in any sub-area of ​​the second large area, and the current working mode of the air conditioning unit is the wind avoidance mode, the first air outlet is the actual air outlet, and the second air outlet is the actual return air outlet. Further, the wind guide angle of the air guide plate at the air outlet is determined according to the specific sub-area where the target position is located. When users appear in the first large area and the second large area at the same time, if the current working mode of the air conditioning unit is the wind avoidance mode, the first air outlet is the actual air outlet, and the second air outlet is the actual return air outlet, because compared with the first air outlet, the air discharged from the second air outlet is more likely to blow to the user. At this time, setting the second air outlet as the return air outlet and setting the first air outlet as the air outlet is more in line with the wind avoidance mode under the current situation. Similarly, if the current working mode of the air-conditioning unit is the wind-follows-people mode, the second air outlet is the actual air outlet, and the first air outlet is the actual return air outlet. The air from the second air outlet is more likely to blow to the user. This setting can better meet the user's wind-follows-people needs.

[0068] Specifically, according to a first preset correspondence between a target sub-area of ​​the target position in the first large area and an angle of the air guide plate in the wind avoidance mode, determining a first air outlet angle of the upper and lower air guide plates and a second air outlet angle of the left and right air guide plates of the second air outlet may include, as an example:

[0069] If the user is in IA or IB, the upper and lower air guide plates are 30° and the left and right air guide plates are 45°;

[0070] If the user is in ⅠC, the upper and lower air guide plates are 30°, and the left and right air guide plates are -45°;

[0071] If the user is in ⅠD or ⅠE, the upper and lower air guide plates are 90°, and the left and right air guide plates are 45°;

[0072] If the user is in ⅠF, the upper and lower air guide plates are 90°, and the left and right air guide plates are -45°.

[0073] According to the first preset correspondence between the target sub-area of ​​the target position in the first large area and the angle of the air guide plate in the wind avoidance mode, the ninth air outlet angle of the upper and lower air guide plates of the first air outlet and the tenth air outlet angle of the left and right air guide plates can be determined by referring to the above examples and will not be repeated here.

[0074] In the embodiment of the present application, if the user is in IA and IB, the upper and lower air guide plates are 30° and the left and right air guide plates are 45° to avoid direct blowing to IA and IB, and blow to IC. If the user is in IC, the upper and lower air guide plates are 30° and the left and right air guide plates are -45° to avoid direct blowing to IC, and blow to IA and IB. In this way, the air supply is prevented from blowing directly to the user, and the air can be sent to the adjacent position of the user, so that the user can quickly feel the temperature change under air circulation even in the wind avoidance mode, which improves the user experience. The air supply settings of other positions are similar, and will not be repeated here.

[0075] According to a second preset correspondence between a target sub-region of the target position in the second large region and an angle of the air guide plate in the wind avoidance mode, determining a third air outlet angle of the upper and lower air guide plates and a fourth air outlet angle of the left and right air guide plates of the first air outlet may include, as an example:

[0076] If the user is in ⅡA or ⅡB, the upper and lower air guide plates are 30° and the left and right air guide plates are 45°;

[0077] If the user is in ⅡC, the upper and lower air guide plates are 30°, and the left and right air guide plates are -45°;

[0078] If the user is in ⅡD or ⅡE, the upper and lower air guide plates are 90°, and the left and right air guide plates are 45°;

[0079] If the user is in ⅡF, the upper and lower air guide plates are 90°, and the left and right air guide plates are -45°.

[0080] In the present application embodiment, Figure 7 As shown, when the target location is in any sub-area of ​​the first large area and the current working mode of the air conditioning unit is the wind-following-people mode, the first air outlet is the actual air outlet and the second air outlet is the actual return air outlet. Figure 8 As shown, when the target position is in any sub-area of ​​the second large area, and the current working mode of the air conditioning unit is the wind-following-people mode, the first air outlet is used as the actual return air outlet, and the second air outlet is used as the actual air outlet. Further, the air guide angle of the air guide plate at the air outlet is determined according to the specific sub-area where the target position is located.

[0081] Specifically, according to the third preset correspondence between the target sub-area of ​​the target position in the first large area and the angle of the air guide plate in the wind following person mode, determining the fifth air outlet angle of the upper and lower air guide plates and the sixth air outlet angle of the left and right air guide plates of the first air outlet, as an example, may include:

[0083] If the user is in IB, the upper and lower air guide plates range from 60° to 90°, and the left and right air guide plates range from -15° to 15°;

[0084] If the user is in ⅠC, the upper and lower air guide plates range from 60° to 90°, and the left and right air guide plates range from 15° to 45°;

[0085] If the user is in ID, the upper and lower air guide plates range from 30° to 60°, and the left and right air guide plates range from -45° to -15°;

[0086] If the user is in ⅠE, the upper and lower air guide plates range from 30° to 60°, and the left and right air guide plates range from -15° to 15°;

[0087] If the user is in ⅠF, the range of the upper and lower air guide plates is 30°~60°, and the range of the left and right air guide plates is 15°~45°.

[0088] In the embodiment of the present application, if the user is in IA, the upper and lower air guide plates have a range of 60° to 90°, and the left and right air guide plates have a range of -45° to -15°, which can directly blow the user located in IA, thereby realizing a precise wind-following mode. Similarly, corresponding to IB, the upper and lower air guide plates have a range of 60° to 90°, and the left and right air guide plates have a range of -15° to 15°, which can directly blow the user located in IB. The air supply settings for other positions are the same and will not be repeated here.

[0089] According to the fourth preset correspondence between the target sub-area of ​​the target position in the second large area and the angle of the air guide plate in the wind following person mode, determining the seventh air outlet angle of the upper and lower air guide plates and the eighth air outlet angle of the left and right air guide plates of the second air outlet may include, as an example:

[0090] If the user is in ⅡA, the upper and lower air guide plates range from 30° to 60°, and the left and right air guide plates range from -45° to -15°;

[0091] If the user is in ⅡB, the upper and lower air guide plates range from 30° to 60°, and the left and right air guide plates range from -15° to 15°;

[0092] If the user is in ⅡC, the upper and lower air guide plates range from 30° to 60°, and the left and right air guide plates range from 15° to 45°;

[0093] If the user is in ⅡD, the upper and lower air guide plates range from 60° to 90°, and the left and right air guide plates range from -45° to -15;

[0094] If the user is in ⅡE, the upper and lower air guide plates range from 60° to 90°, and the left and right air guide plates range from -15° to 15°;

[0095] If the user is in ⅡF, the upper and lower air guide plates have a range of 60° to 90°, and the left and right air guide plates have a range of 15° to 45°.

[0096] According to the fourth preset correspondence between the target sub-area of ​​the target position in the second large area and the angle of the air guide plate in the wind follows people mode, the eleventh air outlet angle of the upper and lower air guide plates and the twelfth air outlet angle of the left and right air guide plates of the second air outlet can be determined by referring to the above examples and will not be repeated here.

[0097] In an optional embodiment, when multiple users are detected in the same large area at the same time, the method further includes:

[0098] Step 1, determining multiple target locations of the multiple users in the same large area;

[0099] Step 2, determining the wind deflector angle of the actual air outlet corresponding to each of the multiple target positions;

[0100] Step 3, superimposing the wind guide plate angles of the actual air outlets corresponding to all the multiple target positions to obtain a first wind sweeping angle of the upper and lower wind guide plates and a second wind sweeping angle of the left and right wind guide plates;

[0101] Step 4: Control the upper and lower air guide plates and the left and right air guide plates to sweep air according to the first air sweeping angle and the second air sweeping angle.

[0102] In an embodiment of the present application, when the system detects that there are multiple users in the first or second region, the specific positions of these users in the same region can be determined first. This can be achieved by the aforementioned infrared sensor, millimeter wave radar, laser radar or camera equipment and other technologies. The system can capture and track the positions of multiple users in real time to ensure that each user is accurately identified and located. The angle of the air guide plate of the corresponding air outlet can be determined according to the target position of each user. The angles of the air guide plates corresponding to all target positions are superimposed to obtain the first sweeping angle of the upper and lower air guide plates and the second sweeping angle of the left and right air guide plates, ensuring that the air outlet strategy can meet the comfort needs of multiple users at the same time. By superimposing the angles of the air guide plates, the system can obtain a sweeping range that can cover multiple target positions. Finally, the system will control the upper and lower air guide plates and the left and right air guide plates to sweep the air according to the calculated first sweeping angle and second sweeping angle. In this way, the air conditioning unit can achieve more uniform and efficient air outlet between multiple users, ensuring that each user can obtain satisfactory comfort. This method not only improves the intelligence level of the air conditioning unit, but also can better meet the comfort needs in a multi-user environment. By precisely controlling the wind sweeping angle of the air guide plate, the system can reduce energy waste while ensuring the air outlet effect, thus achieving the goal of energy saving and environmental protection.
