Description

Technical Field

[0001] The present invention relates to the technical field of air conditioning equipment, and in particular to an air supply control method and device for air conditioning, and an air conditioner. Background Art

[0002] With the improvement of people's living standards, air conditioners have become a necessity in daily life. Air conditioners can heat up and cool down indoor air, thereby providing a comfortable indoor working or resting environment.

[0003] When the indoor unit of an existing air conditioner realizes the function of heating and cooling the room, it generally requires the user to manually adjust the angle of the indoor unit's air guide plate to supply air to the room. However, the angle of the indoor unit's air guide plate is usually not aimed at the human body during periodic operation with fixed working parameters. Only when the angle of the indoor unit's air guide plate is aimed at the user will the body suddenly receive the air-conditioned air directly blown. When the user is suddenly blown directly by the wind from a relaxed state without being blown by the wind, the body will have a short-term stress reaction, which is very likely to cause discomfort to the user in the long run. How to match the appropriate air guide plate operating parameters to improve and ensure the user's wind comfort is a technical problem that technicians in this field urgently need to solve. Summary of the Invention

[0010] Divide N1 air supply zones in the second air sweeping areas on the left and right sides of the first air sweeping area respectively;

[0011] In the process of the vertical swing blade assembly rotating from the left sensing limit to the left boundary of the first air sweeping area at the first swing speed, the air supply speed is reduced from the N1th gear by one gear each time it passes through an air supply zone until it is gradually reduced to the 1st gear;

This reduces the air supply force during rapid sweeps in the horizontal range corresponding to the human body, while increasing it during slow sweeps in the horizontal range outside the human body. This improves the control accuracy and efficiency of the indoor unit's air supply and optimizes the user experience. BRIEF DESCRIPTION OF THE DRAWINGS

[0054] It should be understood that the terms used in this specification are only for the purpose of describing specific embodiments and are not intended to limit the present invention. As used in the present invention, unless the context clearly indicates otherwise, the singular forms "a", "an" and "the" are intended to include the plural forms.

[0055] The terms “include” and “comprising” indicate the presence of described features, integers, steps, operations, elements and / or components, but do not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components and / or groups thereof.

[0056] Figure 1 This is one of the flow charts of the air conditioning air supply control method provided by the present invention. Figure 1 As shown, the air conditioning air supply control method provided by an embodiment of the present invention includes: step 101, when it is determined by a radar module that there is at least one human individual in the radar sensing area, based on the sensing position of the target individual, the radar sensing area is divided into a first sweeping air area where the target individual exists, and a second sweeping air area where the target individual does not exist.

[0057] The radar sensing area is defined by the angle formed by the left sensing limit and the horizontal line at which the radar module is located in the air-conditioning indoor unit, and the angle formed by the right sensing limit and the horizontal line at which the radar module is located in the air-conditioning indoor unit. The first wind sweeping area is defined by the angle formed by the left width boundary of the target individual in the horizontal direction and the horizontal line at which the radar module is located in the air-conditioning indoor unit, and the angle formed by the right width boundary of the target individual in the horizontal direction and the horizontal line at which the radar module is located in the air-conditioning indoor unit. The second wind sweeping area is the complement of the first wind sweeping area in the radar sensing area. The rated wind swing area overlaps with the radar sensing area.

[0058] It should be noted that the execution subject of the air-conditioning air supply control method provided in the embodiment of the present invention is an air-conditioning air supply control device.

[0059] The application scenario of the air conditioning air supply control method provided by an embodiment of the present invention is that when the user activates the air conditioner, the radar module senses the position of the human individual relative to the air conditioning indoor unit, and the sweeping area of ​​the entire vertical swing blade assembly for sweeping the air left and right is divided into a manned area and an unmanned area, and the vertical swing blade assembly is controlled to gradually reduce the air supply speed in the process of slowly transitioning from the unmanned area to the manned area, until it is reduced to the minimum air supply speed and then quickly sweeps through the manned area at the minimum air supply speed, and then the vertical swing blade assembly gradually increases the air supply speed in the process of slowly moving away from the manned area.

[0060] The radar module is fixed to the air conditioner indoor unit. The location of the air conditioner indoor unit serves as the origin of the radar coordinate system. The horizontal plane on which the module resides is the XoY plane of the radar coordinate system. The Z axis is the line perpendicular to the XoY plane and passes through the origin of the coordinate system. Furthermore, in the XoY plane, the horizontal line on which the air conditioner indoor unit resides is the X axis, and the line perpendicular to the X axis in this plane is the Y axis.

[0061] As can be seen, the radar sensing area consists of three dimensions: the left and right sensing limits are distributed on the X-axis, representing the radar module's horizontal scanning range. The sensing limit set on the Y-axis represents the radar module's radiation radius. The upper and lower sensing limits are distributed on the Z-axis, representing the radar module's vertical scanning range.

[0062] Since the scanning process of the radar module in the horizontal direction is highly similar to the process of the vertical swing blade assembly of the air conditioner indoor unit swinging left and right in the horizontal direction, the embodiment of the present application focuses the radar sensing area on the part that overlaps with the rated swing area of ​​the vertical swing blade assembly swinging left and right.

[0063] Therefore, the left perception limit and right perception limit of the radar module distributed on the X-axis are also the left swing limit and right swing limit of the vertical swing blade assembly, respectively. At this time, the radar perception area can be limited by the angle range formed by the line connecting the left perception limit and the right perception limit and the origin of the coordinate system and the X-axis.

[0064] For example, in the X-axis, the direction extending to the left from the origin of the coordinate system is taken as the positive direction of the X-axis, the left perception limit and the right perception limit are symmetrically arranged on both sides of the Y-axis, and the angle formed with the Y-axis is 75°, then the radar perception area can be represented as [15°, 165°].

[0065] It should be noted that the radar module periodically collects the position information of all individuals in the room at a specified time interval and sends the position information to the air conditioning control device. The embodiment of the present invention does not specifically limit the working cycle of the radar module.

[0066] Optionally, the radar module can perform data collection operations in a default working cycle.

[0067] Optionally, the user can issue a cycle change instruction so that the radar module receives and responds to the instruction and changes the working cycle to the cycle indicated by the instruction to perform acquisition operations.

[0068] It should be noted that before step 101, the user needs to send an activation instruction through the transmission medium to activate the working mode of the air conditioner, so that the indoor unit of the air conditioner supplies air to the outside at the default wind speed of the mode, and the outdoor unit operates at the default frequency of the mode.

[0069] Optionally, the user can use the control device to transmit activation instructions through wireless communication between the control device and the air-conditioning system, so that the air-conditioning system initializes the working mode and starts the radar module.

[0070] Optionally, the user can issue an activation command through voice interaction. The air-conditioning system receives the activation command, performs voice recognition, initializes the working mode, and starts the radar module.

[0071] Specifically, in step 101, after the air conditioner starts working mode, the air supply control device of the air conditioner receives the real-time sensing position information collected by the radar module for each individual within its own radar sensing area, and uses this as a basis to divide the air sweeping area:

[0072] If the radar module senses the presence of a human body in the radar sensing area in the horizontal direction, the human individual in the radar sensing area is taken as the target individual. The sensing position of the target individual is combined with the horizontal width of the target individual to deduce the positions of its left width boundary and right width boundary in the radar coordinate system respectively. The first swept wind area is defined by the angle range formed by the position of the left width boundary and the right width boundary in the radar coordinate system and the line connecting the origin of the coordinate system and the X-axis, and the remaining complementary areas in the radar sensing area separated by one or more first swept wind areas are each recorded as the second swept wind area.

[0073] If the radar module senses the presence of a human body outside the radar sensing area in the horizontal direction, it will choose to block it and only track the human body in the sensing area that overlaps with the horizontal wind swing range.

[0074] The first swept wind area represents the area within the radar sensing region where the target individual can reflect the radar module's transmitted signals. The second swept wind area represents the area around the target individual where the radar module's transmitted signals cannot be reflected. This embodiment of the present invention does not specifically limit the type and number of radar sensing devices in the radar module.

[0075] For example, the radar module may include a laser radar, an infrared sensor, etc.

[0076] Optionally, since the horizontal detection range of the millimeter-wave radar can reach ±75°, the vertical detection range can reach ±40°, the maximum detection distance can reach 8 meters, the distance output accuracy can reach 0.1 meters, the angle output accuracy can reach 1°, and it does not involve privacy issues, is not affected by light, and its response speed is also fast.

[0077] Therefore, the air conditioning control device uses the real-time information collected by the millimeter-wave radar, such as movement angle and displacement points, as the user's individual location information. It can also collect information such as acceleration and speed to convert the user's individual location information.

[0078] For example, the radar module may include multiple sensor elements such as millimeter wave radar, lidar, infrared sensor, etc. The air conditioning control device integrates the behavioral information collected by each sensor element to comprehensively depict the individual's current location information.

[0079] Step 102: Based on the first sweeping wind area and the second sweeping wind area, adjust the air supply wind speed and the swing speed of the vertical swing blade assembly in the rated swing wind area.

[0080] Specifically, in step 102, the air supply control device uses the angular range defined by the first sweeping area surrounding the target individual as a weakened swinging area, and the angular range defined by the second sweeping area surrounding the target individual as a strengthened swinging area. The device then encapsulates the positional information of the first and second sweeping areas into swinging and air supply control instructions, which are then transmitted to the air conditioner indoor unit.

[0081] The air conditioner indoor unit receives and responds to the swing control command and the air supply control command. While controlling the vertical swing blade assembly to swing back and forth within the rated swing range, the fan continuously delivers conditioned air. Based on the angular ranges indicated by the analyzed first and second sweep air regions, the vertical swing blade assembly's left-right swing speed is reduced within the enhanced swing range, and increased within the weakened swing range. Furthermore, the air supply speed of the vertical swing blade assembly in any enhanced swing range is greater than or equal to the air supply speed of the vertical swing blade assembly in any weakened swing range.

[0082] Based on the radar module's perception of individual locations, this embodiment of the present invention divides a first sweeping area where humans are present and a second sweeping area where they are absent. This reduces the airflow force when the vertical swing blade assembly rapidly passes through the first sweeping area, while increasing it when it slowly passes through the second sweeping area. This optimizes the swing speed of the vertical guide plate within the corresponding range when the horizontal coverage area changes due to movement. This reduces the airflow force during rapid sweeps in the horizontal range corresponding to the human body, while increasing it during slow sweeps in the horizontal range outside the human body. This improves the control accuracy and efficiency of the indoor unit's air supply and optimizes the user experience.

[0083] Based on any of the above embodiments, when it is determined that the number of the target individuals is 1, the swing speed of the vertical swing blade assembly within the rated swing area is adjusted based on the first sweeping area and the second sweeping area, including: dividing n1 air supply partitions in the second sweeping area on the left and right sides of the first sweeping area respectively.

[0084] Specifically, in step 102, if the number of target individuals detected in the radar sensing area is one, the air supply control device uses the angular range defined by the first sweeping air zone in which the target individual is located as the weakened swing air zone, and uses the angular ranges defined by the two second sweeping air zones separated by the target individual from the radar sensing area as the strengthened swing air zones. Furthermore, each second sweeping air zone on the left and right sides of the target individual is divided into N1 air supply zones.

[0085] Among them, it is necessary to make corresponding divisions within the threshold range of the fan speed according to the proportion of each air supply zone in the angle range defined by the second air sweeping area, so as to form air supply speed gears corresponding to the air supply zones one by one.

[0086] In the process of the vertical swing blade assembly rotating from the left sensing limit to the left boundary of the first wind sweeping area at the first swing speed, the air supply wind speed is reduced by one gear from the N1 gear every time it passes through an air supply zone until it decreases to the 1st gear.

[0087] When the vertical swing blade assembly rotates from the left boundary of the first wind sweeping area to the right boundary of the first wind sweeping area at the second swing speed, the air supply speed is maintained at the first gear.

[0088] In the process of the vertical swing blade assembly rotating from the right boundary of the first wind sweeping area to the right perception limit at the first swing speed, the air supply wind speed is increased by one gear from the first gear every time it passes through an air supply zone until it decreases to the N1 gear.

[0089] Wherein, the first swing speed is smaller than the second swing speed.

[0090] Specifically, the air supply control device of the air conditioner performs the following steps when controlling the air supply mode of the air conditioner indoor unit using the swing control instruction and the air supply control instruction:

[0091] As the vertical swing blade assembly swings at a lower first swing speed within the second sweeping air zone to the left of the target individual, the air supply speed is sequentially reduced by one level each time it passes through a supply air zone. Specifically, if the vertical swing blade assembly swings from the left sensing limit to the left boundary of the first sweeping air zone, the air supply speed is correspondingly reduced from the N1th level to the 1st level. Conversely, if the air supply speed increases as the vertical swing blade assembly swings from the left boundary of the first sweeping air zone to the left sensing limit, the air supply speed is correspondingly increased from the 1st level to the N1th level.

[0092] After the vertical swing blade assembly sweeps the second wind sweeping area on the left side of the target individual, the air supply speed is maintained at the first gear, and the vertical swing blade assembly periodically changes the wind direction of the first gear wind force in the first wind sweeping zone at a higher second swing speed.

[0093] After the vertical swing blade assembly passes through the first sweeping area, it returns to the lower first swing speed and swings within the second sweeping area to the right of the target individual. The air supply speed is increased by one level each time it passes through a supply air zone. That is, if the vertical swing blade assembly rotates from the right boundary of the first sweeping area to the right sensing limit, the air supply speed is correspondingly increased from level 1 to level N1. Conversely, if the air supply speed decreases as it rotates from the right sensing limit to the right boundary of the first sweeping area, the air supply speed is correspondingly decreased from level N1 to level 1.

[0094] For example, Figure 2 This is one of the schematic diagrams of the partitioning of the wind sweeping area provided by the present invention. Figure 2 As shown, the embodiment of the present invention takes the value of N1 as 5 as an example, and provides a specific implementation of an air conditioning air supply control method with the number of target individuals being 1:

[0095] When the number of targets is 1, the angles between the target's left and right boundaries (in terms of width) and the X-axis constitute the first swept area (denoted as [left boundary, right boundary]). Similarly, based on the angles between the radar module's left and right sensing limits and the X-axis, the second swept area to the left of the target is denoted as [left sensing limit, left boundary], while the second swept area to the right of the target is denoted as [right boundary, right sensing limit]).

[0096] Each second air sweep zone is divided into five supply air zones, resulting in a total of 11 zones within the radar sensing area. As the vertical swing blade assembly rotates from the left sensing limit to the right sensing limit, starting from the first supply air zone at [left sensing limit, left boundary], the air speed is reduced by one level with each air zone passed, based on the air speed at the fifth level, at a lower first swing speed, until it reaches the first level at the last air zone at [left sensing limit, left boundary]. After crossing the left boundary, the swing blade assembly's swing speed is increased from the first swing speed to the second swing speed, maintaining the air speed at the first level as it sweeps across the first air sweep zone from left to right. Next, starting from the first supply air zone at [right boundary, right sensing limit], the air speed is increased by one level with each air zone passed, based on the air speed at the first level, at a lower first swing speed, until it reaches the fifth level at the last air zone at [right boundary, right sensing limit].

[0097] Similarly, as the vertical swing blade assembly rotates from the right sensing limit to the left sensing limit, starting from the last air supply zone at [right boundary, right sensing limit], based on the air supply speed at the 5th gear, the first swing speed is lowered by one gear with each air supply zone passed, until the air supply speed is reduced to the 1st gear at the first air supply zone at [right boundary, right sensing limit]. Subsequently, after crossing the right boundary, the swing speed of the vertical swing blade assembly is increased from the first swing speed to the second swing speed, and the air supply speed is maintained at the 1st gear as it sweeps across the first sweeping area from right to left. Immediately thereafter, starting from the last air supply zone at [left sensing limit, left boundary], based on the air supply speed at the 1st gear, the first swing speed is increased by one gear with each air supply zone passed, until the air supply speed is reduced to the 5th gear at the first air supply zone at [left sensing limit, left boundary].

[0098] When only one human individual is detected within the sensing range, the embodiment of the present invention divides the second sweeping area where no human individual is present, and sets different air supply speeds for the divided areas in order, so that the air supply force gradually weakens as the vertical swing blade assembly slowly approaches the first sweeping area within the second sweeping area, and gradually increases as the vertical swing blade assembly slowly moves away from the first sweeping area within the second sweeping area. This optimizes the swing speed of the vertical guide plate within the corresponding range, and causes the air conditioner to weaken the air force when rapidly sweeping in the horizontal range corresponding to the human body, while gradually weakening the air force when slowly approaching the human body in the horizontal range other than the human body, and gradually increasing the air force when slowly moving away from the human body. This improves the control accuracy and efficiency of the indoor unit's air supply, and optimizes the user's experience of being protected from the wind by people.

[0099] On the basis of any of the above embodiments, when the number of the target individuals is determined to be k, the swing speed of the vertical swing blade assembly in the rated swing wind area is adjusted based on the first wind sweeping area and the second wind sweeping area, including: dividing the first second wind sweeping area and the k+1th second wind sweeping area into N2 air supply partitions, and dividing the other second wind sweeping areas except the first second wind sweeping area and the k+1th second wind sweeping area into 2N2-1 air supply partitions.

[0100] Specifically, in step 102, if the number of target individuals sensed within the radar sensing area is k, the air supply control device uses the angular ranges defined by the first sweeping wind areas where the target individuals are located as k weakened swing wind areas, and the angular ranges defined by the second sweeping wind areas separated by the k target individuals from the radar sensing area as k+1 enhanced swing wind areas. Furthermore, N2 air supply zones are created in the first and k+1 second sweeping wind areas, respectively, on the left and right sides of the radar sensing area. The remaining second sweeping wind areas between any two target individuals are also created into 2N2 air supply zones, so that the zones encompass the unmanned area to the right of the previous target individual and the unmanned area to the left of the next target individual.

[0101] Here, k is a positive integer greater than 1.

[0102] During the process of the vertical swing blade assembly sensing the area from the radar, the current position of the vertical swing blade assembly is obtained.

[0103] If the current position of the vertical swing blade assembly is within any first wind sweeping area, the vertical swing blade assembly is controlled to swing within the first wind sweeping area at a third swing speed, and the air supply speed is maintained at the first gear.

[0104] If the current position of the vertical swing blade assembly is in the first second air sweeping area, when controlling the vertical swing blade assembly to rotate counterclockwise at the fourth swing speed, the air supply speed is reduced by one gear each time it passes through an air supply zone until it decreases from the N2 gear to the 1st gear.

[0105] If the current position of the vertical swing blade assembly is in the k+1th second air sweeping area, when controlling the vertical swing blade assembly to rotate counterclockwise at the fourth swing speed, the air supply speed is increased by one gear each time it passes through an air supply zone, until it increases from the 1st gear to the N2th gear.

[0106] If the current position of the vertical swing blade assembly is in other second sweep air areas other than the 1st second sweep air area and the k+1th second sweep air area, in the process of controlling the vertical swing blade assembly to rotate from the 1st air supply zone to the N2th air supply zone at the fourth swing speed, the air supply speed is increased by one gear each time an air supply zone is passed until it increases from the 1st gear to the N2th gear.

[0107] In the process of controlling the vertical swing blade assembly to rotate from the N2+1th air supply zone to the 2N2-1th air supply zone at the fourth swing speed, the air supply wind speed is reduced by one gear each time an air supply zone is passed until it decreases from the N2th gear to the 1st gear.

[0108] Wherein, the third swing speed is greater than the fourth swing speed.

[0109] Specifically, when the vertical swing blade assembly swings back and forth within the range of the radar sensing area, the air supply control device of the air conditioner obtains the current position of the vertical swing blade assembly in real time, and performs the following steps to control the air supply mode of the air conditioner indoor unit in combination with the swing control instruction and the air supply control instruction:

[0110] When the vertical swing blade assembly swings at a lower first swing speed within the first and second air sweeping zones, the air supply speed is sequentially reduced by one level each time it passes through each air supply zone. That is, if the vertical swing blade assembly rotates from the left sensing limit to the right boundary of the second air sweeping zone, the air supply speed is correspondingly reduced from the N2th level to the 1st level. Conversely, if the air supply speed increases when the vertical swing blade assembly rotates from the right boundary of the second air sweeping zone to the left sensing limit, the air supply speed is correspondingly increased from the 1st level to the N2th level.

[0111] After the vertical swing blade assembly sweeps through the first second wind sweeping area, the air supply speed is maintained at the first gear, and the vertical swing blade assembly periodically changes the wind direction of the first gear wind in the first first wind sweeping zone at a higher second swing speed.

[0112] Then, after the vertical swing blade assembly sweeps through the first first wind sweeping area, it returns to the lower first swing speed and swings in the second second wind sweeping area. After the air supply speed is increased by one gear each time it passes through an air supply partition in the uninhabited area on the right side of the first target individual, the air supply speed is decreased by one gear each time it passes through an air supply partition in the uninhabited area on the left side of the second target individual. That is, if it rotates from the left boundary of the second first wind sweeping area to the partition boundary, the air supply speed is increased from the 1st gear to the N2th gear, and then rotates from the partition boundary to the right boundary of the second first wind sweeping area, the air supply speed is decreased from the N2th gear to the 1st gear. Conversely, if it rotates from the right boundary to the left boundary of the second first wind sweeping area, the air supply speed is increased first and then decreased.

[0113] After the vertical swing blade assembly sweeps through the second second sweeping area, the air supply speed is maintained at the first gear, and the vertical swing blade assembly periodically changes the wind direction of the first gear wind at a higher second swing speed in the second first sweeping zone.

[0114] Repeat multiple rounds until the vertical swing blade assembly swings at a lower first swing speed within the k+1th second sweeping air zone, increasing the supply air speed by one level each time it passes through a supply air zone. That is, if the vertical swing blade assembly rotates from the right boundary of the k+1th second sweeping air zone to the right sensing limit, the supply air speed will correspondingly increase from the 1st level to the N2th level. Conversely, if the supply air speed decreases when the vertical swing blade assembly rotates from the right sensing limit to the right boundary of the k+1th second sweeping air zone, the supply air speed will correspondingly decrease from the N2th level to the 1st level.

[0115] For example, Figure 3 This is the second schematic diagram of the partition of the wind sweeping area provided by the present invention. Figure 3 As shown, in this embodiment of the present invention, N2 and N1 are both 5 as an example, and a specific implementation method of an air conditioning air supply control method with 2 target individuals is given:

[0116] When the number of target individuals is 2, the angle between the left boundary of the first target individual and the X-axis, and the angle between the right boundary of the first target individual and the X-axis, constitute the first wind sweep area (denoted as [left boundary 1, right boundary 1]). Similarly, the first wind sweep area of ​​the second target individual is denoted as [left boundary 2, right boundary 2].

[0117] Combined with the angles between the left perception limit and the right perception limit of the radar module and the X-axis, the first second wind sweep area on the left side of the first target individual is recorded as [left perception limit, left boundary 1], and the second second wind sweep area between the first and second target individuals is recorded as [right boundary 1, (right boundary 1 + left boundary 2) / 2], and the third second wind sweep area on the right side of the second target individual is recorded as [right boundary 2, right perception limit].

[0118] The first and third second sweep air zones are divided into five supply air zones, respectively, and the second second sweep air zone is divided into nine supply air zones. The radar sensing area can now be divided into 21 zones. As the vertical swing blade assembly rotates from the left sensing limit to the right sensing limit, starting from the first supply air zone at [left sensing limit, left boundary 1], the supply air speed is reduced by one level with each passing supply air zone, based on the supply air speed at the fifth level, at the lower first swing speed, until the supply air speed is reduced to the first level at the last supply air zone at [left sensing limit, left boundary 1]. Subsequently, after crossing left boundary 1, the swing speed of the vertical swing blade assembly is increased from the first swing speed to the second swing speed, and the supply air speed is maintained at the first level as it sweeps across the first first sweep air zone from left to right.

[0119] Next, starting from the first air supply zone of [right boundary 1, (right boundary 1 + left boundary 2) / 2], based on the air supply wind speed of the first gear, the lower first swing speed is increased by one gear each time an air supply zone is passed, until the air supply wind speed is increased to the fifth gear after reaching the N2th air supply zone. Then, starting from the N2th air supply zone, based on the air supply wind speed of the fifth gear, the lower first swing speed is reduced by one gear each time an air supply zone is passed, until the air supply wind speed is reduced to the first gear after reaching the 2N2-1th air supply zone. Subsequently, after crossing (right boundary 1 + left boundary 2) / 2, the swing speed of the vertical swing blade assembly is increased from the first swing speed to the second swing speed, and the air supply wind speed is maintained at the first gear and sweeps through the second first sweeping area from left to right.

[0120] Finally, starting from the first air supply zone of [right boundary 2, right perception limit], based on the air supply speed at the first gear, the air supply speed is reduced by one gear each time a air supply zone is passed at a lower first swing speed until the air supply speed is reduced to the first gear in the last air supply zone of [right boundary 2, right perception limit].

[0121] Similarly, when the vertical swing leaf assembly rotates from the right sensing limit to the left sensing limit, the reverse adjustment of the above process can be performed, which will not be repeated here.

[0122] When only multiple human individuals are sensed within the sensing range, the embodiment of the present invention divides the second air sweeping areas with different distributions into different areas, and sets different air supply speeds for the divided areas in order, so that the vertical swing blade assembly gradually increases the air supply wind force when slowly moving away from the first air sweeping area where the first target individual is located between two adjacent target individuals, and then gradually decreases the air supply wind force when slowly approaching the first air sweeping area where the second target individual is located. This optimizes the control of the swing speed of the vertical guide plate within the corresponding range, and causes the air conditioner to decrease the wind force when rapidly sweeping the air in the horizontal range corresponding to the human body, and gradually decrease the wind force when slowly approaching the human body in the non-human horizontal range, and gradually increase the wind force when slowly moving away from the human body, thereby improving the control accuracy and efficiency of the indoor unit's air supply and optimizing the user's experience of being blown away by the wind.

[0123] On the basis of any of the above embodiments, before dividing the first second wind sweeping area and the k+1th second wind sweeping area into N2 air supply zones, and dividing the other second wind sweeping areas except the first second wind sweeping area and the k+1th second wind sweeping area into 2N2-1 air supply zones, it also includes: determining the relative distance between any two adjacent target individuals based on the perception position obtained by the radar module scanning each target individual.

[0124] Specifically, if the number of target individuals sensed by the air conditioning control device in the radar sensing area is k, the relative distance between the target individual and its adjacent target individuals in the radar coordinate system is calculated using the sensed position of each target individual in the radar coordinate system.

[0125] The embodiment of the present invention does not specifically limit the method for calculating the relative distance between any two adjacent target individuals.

[0126] For example, the distance between the two coordinate points can be directly calculated using the perceived position coordinate values ​​of two adjacent target individuals in the radar coordinate system as the relative distance between the two.

[0127] For example, the azimuth angle difference between two adjacent target individuals and the origin of the radar coordinate system can be directly calculated as the relative distance.

[0128] According to the relative distance between any two adjacent target individuals, the target individuals are clustered, and the k value is updated by the number of clusters obtained by clustering, and the updated k value is output.

[0129] Wherein, the updated k value is greater than or equal to 1.

[0130] Specifically, the air conditioning control device performs cluster analysis based on the relative distance between any two adjacent target individuals. Clusters of relatively close target individuals are considered as a whole, and the number of target individuals, k, is updated based on the number of clusters. Furthermore, the first sweep area is defined based on the angular range of the clusters in the radar coordinate system. The second sweep area is further analyzed based on the number of clusters:

[0131] If the updated k value is still greater than 2, then Figure 3 The partitioning method in the multi-person scenario shown is used to divide the no-man's land and execute the corresponding control process.

[0132] If the updated k value is equal to 1, then Figure 2 The partitioning method in the single-person scenario shown is used to divide the no-person area and execute the corresponding control process.

[0133] When multiple human individuals are detected within the sensing range, this embodiment of the present invention clusters them based on their distribution, treating those individuals who are closer together as a whole. It then divides the second sweeping area into different zones, and sets different air supply speeds accordingly based on the zones. This reduces unnecessary control, improves the control accuracy and efficiency of the indoor unit's air supply, and optimizes the user's experience of avoiding the wind blowing on them.

[0134] On the basis of any of the above embodiments, after adjusting the air supply speed and the swing speed of the vertical swing blade assembly within the rated swing area based on the first sweeping area and the second sweeping area, it also includes: when it is determined that the working mode is the cooling mode, determining the first execution position through the first azimuth angle collected by the radar module on the target individual.

[0135] The first azimuth angle is the azimuth angle of the target individual's human foot relative to the radar module.

[0136] Specifically, after step 102, the air supply control device of the air conditioner can adjust the swing speed of the vertical swing blade assembly and the air supply speed of the air conditioner, and can also adjust the swing range of the horizontal swing blade assembly according to the working mode activated by the air conditioner, in the following manner:

[0137] If the air-conditioning air supply control device determines that the activated working mode of the air conditioner is the cooling mode based on the operating status of the indoor unit and the outdoor unit of the air conditioner, the first execution position corresponding to the height of the human foot on the Z axis is determined based on the first azimuth angle collected by scanning the vertical height of the target individual through the radar module, combined with the mapping relationship between the height range and the execution angle.

[0138] The first azimuth angle is the angle between the line connecting the foot of a target individual indoors and the origin of the coordinate system and the XoY plane. The first azimuth angle is used to represent the foot position of the target individual.

[0139] When it is determined that the vertical swing blade assembly is in the first wind sweeping area, the transverse swing blade assembly is controlled to swing between the first execution position and the lower limit position.

[0140] The lower limit position is the lower boundary of the rated swing wind range of the swing blade assembly.

[0141] Specifically, when the air conditioning air supply control device determines based on the operating status of the vertical swing blade assembly that the vertical swing blade assembly has entered the first sweeping air zone to perform left and right sweeping, it controls the horizontal swing blade assembly to swing up and down between the first execution position and the lower limit position. Once the vertical swing blade assembly leaves the first sweeping air zone, the horizontal swing blade assembly is restored to swing up and down between the upper and lower boundaries of its rated swing range.

[0142] In cooling mode, this embodiment of the present invention determines a first execution position based on the foot position detected by radar scanning of the module's target individual. This first execution position is then updated to the upper boundary of the horizontal blade assembly's swing range. This allows the vertical blade assembly to rapidly pass through the first sweeping area, reducing the force of the cooling air, while also controlling the horizontal blade assembly to sweep air below the person's feet. When the vertical blade assembly is aimed at a person, the horizontal blade assembly's swing range is altered to direct the cooling air downward, eliminating the need for cooling the soles of the feet and optimizing the user experience.

[0143] On the basis of any of the above embodiments, after adjusting the air supply speed and the swing speed of the vertical swing blade assembly within the rated swing area based on the first sweeping area and the second sweeping area, it also includes: when it is determined that the working mode is the heating mode, determining the second execution position through the second azimuth angle collected by the radar module on the target individual.

[0144] The second azimuth angle is the azimuth angle of the target individual's head relative to the radar module.

[0145] Specifically, after step 102, the air supply control device of the air conditioner can adjust the swing speed of the vertical swing blade assembly and the air supply speed of the air conditioner, and can also adjust the swing range of the horizontal swing blade assembly according to the working mode activated by the air conditioner, in the following manner:

[0146] If the air-conditioning air supply control device determines that the activated working mode of the air conditioner is the heating mode based on the operating status of the indoor unit and the outdoor unit of the air conditioner, the second execution position corresponding to the height of the human head on the Z axis is determined based on the second azimuth angle collected by scanning the vertical height of the target individual through the radar module, combined with the mapping relationship between the height range and the execution angle.

[0147] The second azimuth angle is the angle between the line connecting the head of a target individual indoors and the origin of the coordinate system and the XoY plane. The second azimuth angle is used to represent the head position of the target individual.

[0148] When it is determined that the vertical swing blade assembly is in the first wind sweeping area, the transverse swing blade assembly is controlled to swing between the second execution position and the upper limit position.

[0149] The upper limit position is the upper boundary of the rated swing wind range of the swing blade assembly.

[0150] Specifically, if the air conditioning air supply control device determines based on the operating status of the vertical swing blade assembly that the vertical swing blade assembly has entered the first sweeping air zone and is performing left and right sweeping air, it controls the horizontal swing blade assembly to swing up and down between the upper limit position and the second execution position. Once the vertical swing blade assembly leaves the first sweeping air zone, the horizontal swing blade assembly is restored to swing up and down between the upper and lower boundaries of its rated swing range.

[0151] Figure 4 This is the second flow chart of the air conditioning air supply control method provided by the present invention. Figure 4 As shown, a specific implementation method of an air conditioning air supply control method is given:

[0152] (1) Activate the air conditioner and initialize the millimeter-wave air conditioning radar to sense the location of the person within the rated swing range (150°) of the vertical swing blade assembly.

[0153] (2) Determine whether the person is within the rated swing range of the vertical swing blade assembly. If so, control the radar to capture the target individual in the horizontal angle span α and automatically shield the human individual who is not in the swing area.

[0154] (3) Capture the left and right boundaries of the target individual and adaptively divide the angle from the left boundary to the left limit into 5 zones. Similarly, the right side is also adaptively divided.

[0155] (4) When the vertical swing blade assembly is controlled to swing left and right, the swing angular velocity of the vertical swing blade assembly in the unmanned areas on the left and right sides is 1 / 3V, and the swing angular velocity of the vertical swing blade assembly in the manned area where the target individual is located is V. Wherein, V is the fixed angular velocity of the non-adaptive swing wind.

[0156] (5) The left and right unmanned areas are respectively in the direction away from the manned area where the target individual is located, and the air supply speed is set to 5, 4, 3, 2, and 1 accordingly. Moreover, the air supply speed of the manned area α where the target individual is located is set to 1.

[0157] (6) Determine whether the activated working mode of the air conditioner is the cooling mode. If it is the cooling mode, execute step (7); if it is the heating mode, execute step (8).

[0158] (7) The radar captures and calculates the foot angle of the target person, and controls the swing of the cross guide plate to prevent the cold air from blowing over the soles of the feet.

[0159] (8) The radar captures and calculates the head angle of the target person, and controls the swing of the cross guide plate so that the hot air does not blow over the head.

[0160] In heating mode, this embodiment of the present invention determines a second execution position based on the radar-sensed head position of the module's target individual. This second execution position is then updated to the lower boundary of the horizontal blade assembly's swing range. This allows the vertical blade assembly to rapidly pass through the first sweeping area, reducing the force of the hot air supply, while also controlling the horizontal blade assembly to sweep air above the person's head. When the vertical blade assembly is aimed at a person, the horizontal blade assembly's swing range is altered to cause the hot air to float downward, allowing heating to pass overhead, thus optimizing the user experience.

[0161] Figure 5 Schematic diagram of the structure of the air-conditioning air supply control device provided by the present invention. Figure 5 As shown, the air supply control device for air conditioning provided by the embodiment of the present invention includes a partition module 510 and an air supply control module 520, wherein:

[0162] The partitioning module 510 is used to divide the radar perception area into a first sweeping area where the target individual exists and a second sweeping area where the target individual does not exist based on the perception position of the target individual when the radar module determines that there is at least one human individual in the radar perception area.

[0163] The air supply control module 520 is used to adjust the air supply speed and the swing speed of the vertical swing blade assembly in the rated swing area based on the first sweeping area and the second sweeping area.

[0164] The radar sensing area is defined by the angle formed by the left sensing limit and the horizontal line at which the radar module is located in the air-conditioning indoor unit, and the angle formed by the right sensing limit and the horizontal line at which the radar module is located in the air-conditioning indoor unit. The first wind sweeping area is defined by the angle formed by the left width boundary of the target individual in the horizontal direction and the horizontal line at which the radar module is located in the air-conditioning indoor unit, and the angle formed by the right width boundary of the target individual in the horizontal direction and the horizontal line at which the radar module is located in the air-conditioning indoor unit. The second wind sweeping area is the complement of the first wind sweeping area in the radar sensing area. The rated wind swing area overlaps with the radar sensing area.

[0165] Specifically, the partition module 510 and the air supply control module 520 are electrically connected in sequence.

[0166] After the air conditioner starts working, the partition module 510 receives the real-time sensing position information collected by the radar module for each entity within its own radar sensing area, and uses this as a basis to divide the wind sweeping area:

[0167] If the radar module senses the presence of a human body in the radar sensing area in the horizontal direction, the human individual in the radar sensing area is taken as the target individual. The sensing position of the target individual is combined with the horizontal width of the target individual to deduce the positions of its left width boundary and right width boundary in the radar coordinate system respectively. The first swept wind area is defined by the angle range formed by the position of the left width boundary and the right width boundary in the radar coordinate system and the line connecting the origin of the coordinate system and the X-axis, and the remaining complementary areas in the radar sensing area separated by one or more first swept wind areas are each recorded as the second swept wind area.

[0168] If the radar module senses the presence of a human body outside the radar sensing area in the horizontal direction, it will choose to block it and only track the human body in the sensing area that overlaps with the horizontal wind swing range.

[0169] The air supply control module 520 uses the angular range defined by the first sweeping area surrounding the target individual as a weakened swing air zone, and the angular range defined by the second sweeping area surrounding the target individual as a strengthened swing air zone. The module then packages the positional information of the first and second sweeping areas into swing air control instructions and air supply control instructions, which are then sent to the air conditioner indoor unit.

[0170] The air conditioner indoor unit receives and responds to the swing control command and the air supply control command. While controlling the vertical swing blade assembly to swing back and forth within the rated swing range, the fan continuously delivers conditioned air. Based on the angular ranges indicated by the analyzed first and second sweep air regions, the vertical swing blade assembly's left-right swing speed is reduced within the enhanced swing range, and increased within the weakened swing range. Furthermore, the air supply speed of the vertical swing blade assembly in any enhanced swing range is greater than or equal to the air supply speed of the vertical swing blade assembly in any weakened swing range.

[0171] Optionally, the air supply control module 520 includes a first air supply dividing unit, a first control unit, a second control unit, and a third control unit, wherein:

[0172] The first air supply dividing unit is used to divide the second air sweeping areas located on the left and right sides of the first air sweeping area into N1 air supply zones respectively.

[0173] The first control unit is used to reduce the air supply speed from the N1th gear by one gear each time an air supply zone is passed during the process of the vertical swing blade assembly rotating from the left sensing limit to the left boundary of the first wind sweeping area at a first swinging speed, until it decreases to the 1st gear.

[0174] The second control unit is used to maintain the air supply speed at the first gear when the vertical swing blade assembly rotates from the left boundary of the first wind sweeping area to the right boundary of the first wind sweeping area at a second swinging speed.

[0175] The third control unit is used to increase the air supply speed from the first gear by one gear each time an air supply zone is passed during the process of the vertical swing blade assembly rotating from the right boundary of the first wind sweeping area to the right perception limit at the first swing speed, until it decreases to the N1 gear.

[0176] Wherein, the first swing speed is smaller than the second swing speed.

[0177] Optionally, the air supply control module 520 includes a second air supply division unit, a vertical swing blade acquisition unit and a fourth control unit, wherein:

[0178] The second air supply division unit is used to divide the 1st second air sweeping area and the k+1th second air sweeping area into N2 air supply partitions respectively, and also divide the other second air sweeping areas except the 1st second air sweeping area and the k+1th second air sweeping area into 2N2-1 air supply partitions.

[0179] The vertical swing leaf acquisition unit is used to obtain the current position of the vertical swing leaf assembly when the vertical swing leaf assembly is in the radar sensing area.

[0180] The fourth control unit is used to control the vertical swing blade assembly to swing at a third swing speed in any first wind sweeping area and maintain the air supply speed at the first gear if the current position of the vertical swing blade assembly is in any first wind sweeping area.

[0181] If the current position of the vertical swing blade assembly is in the first second air sweeping area, when controlling the vertical swing blade assembly to rotate counterclockwise at the fourth swing speed, the air supply speed is reduced by one gear each time it passes through an air supply zone until it decreases from the N2 gear to the 1st gear.

[0182] If the current position of the vertical swing blade assembly is in the k+1th second air sweeping area, when controlling the vertical swing blade assembly to rotate counterclockwise at the fourth swing speed, the air supply speed is increased by one gear each time it passes through an air supply zone, until it increases from the 1st gear to the N2th gear.

[0183] If the current position of the vertical swing blade assembly is in other second sweep air areas other than the 1st second sweep air area and the k+1th second sweep air area, in the process of controlling the vertical swing blade assembly to rotate from the 1st air supply zone to the N2th air supply zone at the fourth swing speed, the air supply speed is increased by one gear each time an air supply zone is passed until it increases from the 1st gear to the N2th gear.

[0184] In the process of controlling the vertical swing blade assembly to rotate from the N2+1th air supply zone to the 2N2-1th air supply zone at the fourth swing speed, the air supply wind speed is reduced by one gear each time an air supply zone is passed until it decreases from the N2th gear to the 1st gear.

[0185] The third swing speed is greater than the fourth swing speed; and the value of k is a positive integer greater than 1.

[0186] Optionally, the device further includes a relative distance acquisition module and an individual clustering module, wherein:

[0187] The relative distance acquisition module is used to determine the relative distance between any two adjacent target individuals based on the sensed position obtained by the radar module scanning each target individual.

[0188] The individual clustering module is used to cluster the target individuals according to the relative distance between any two adjacent target individuals, and update the k value with the number of clusters obtained by clustering, and output the updated k value.

[0189] Wherein, the updated k value is greater than or equal to 1.

[0190] Optionally, the device further includes a first execution position acquisition module and a first up and down sweeping module, wherein:

[0191] The first execution position acquisition module is used to determine the first execution position through the first azimuth angle collected by the radar module from the target individual when the working mode is determined to be the cooling mode.

[0192] The first up-and-down wind sweeping module is used to control the horizontal swing blade assembly to swing between the first execution position and the lower limit position when it is determined that the vertical swing blade assembly is in the first wind sweeping area.

[0193] Among them, the first azimuth angle is the azimuth angle of the target individual's human foot relative to the radar module; the lower limit position is the lower boundary of the rated swing wind range of the swing blade assembly.

[0194] Optionally, the device further includes a second execution position acquisition module and a second up and down sweeping module, wherein:

[0195] The second execution position acquisition module is used to determine the second execution position through the second azimuth angle collected by the radar module from the target individual when the working mode is determined to be the heating mode.

[0196] The second up and down wind sweeping module is used to control the horizontal swing blade assembly to swing between the second execution position and the upper limit position when it is determined that the vertical swing blade assembly is in the first wind sweeping area.

[0197] Among them, the second azimuth angle is the azimuth angle of the target individual's head relative to the radar module; the upper limit position is the upper boundary of the rated swing wind range of the swing blade assembly.

[0198] The air conditioning air supply control device provided in an embodiment of the present invention is used to execute the above-mentioned air conditioning air supply control method of the present invention. Its implementation method is consistent with the implementation method of the air conditioning air supply control method provided by the present invention, and can achieve the same beneficial effects, which will not be repeated here.

[0199] Based on the radar module's perception of individual locations, this embodiment of the present invention divides a first sweeping area where humans are present and a second sweeping area where they are absent. This reduces the airflow force when the vertical swing blade assembly rapidly passes through the first sweeping area, while increasing it when it slowly passes through the second sweeping area. This optimizes the swing speed of the vertical guide plate within the corresponding range when the horizontal coverage area changes due to movement. This reduces the airflow force during rapid sweeps in the horizontal range corresponding to the human body, while increasing it during slow sweeps in the horizontal range outside the human body. This improves the control accuracy and efficiency of the indoor unit's air supply and optimizes the user experience.

The indoor unit 610 is provided with a control processor 611 and a radar module 612. The radar module 612 is provided in the indoor unit 610. The air conditioner also includes a memory and a program or instruction stored in the memory and executable on the control processor 611. When the program or instruction is executed by the control processor, the air supply control method of the air conditioner is executed.

[0201] The radar module 612 includes a millimeter wave radar.

[0202] Specifically, the air conditioner comprises an indoor unit 610 and an outdoor unit 620. A control processor 611, which can be integrated into the control development board of the indoor unit 610 as a single chip or microprocessor, communicates with the indoor unit 610 and radar module 612, respectively. Based on real-time feedback of individual location information, the radar sensing area is divided into occupied and unoccupied areas to adjust the operating range of the indoor unit's guide plate. The vertical swing blade assembly is controlled to continuously deliver conditioned air through the fan while reciprocating within the rated swing air area. Based on the angular ranges indicated by the analyzed first and second sweep air areas, the vertical swing blade assembly's left-right swing speed is reduced within the enhanced swing air area and increased within the weakened swing air area. Furthermore, the air supply speed of the vertical swing blade assembly in any enhanced swing air area is greater than or equal to the air supply speed of the vertical swing blade assembly in any weakened swing air area.

[0203] It is also necessary to set one or more radar modules 612 on the surface of the indoor unit 610 at the non-air outlet position to collect the movement status of individual users in the room in real time for real-time monitoring, and feed it back to the control processor 611 for logical judgment of the guide plate control.

[0204] Preferably, the radar module 612 is composed of a millimeter wave radar. The control processor 611 uses wireless communication technology to transmit signals with the motor of the indoor unit 610, the radar module 612, and the light array.

[0205] Among them, wireless communication technology includes but is not limited to WIFI wireless cellular signals (2G, 3G, 4G, 5G), Bluetooth, Zigbee and other methods, which are not specifically limited in the embodiments of the present invention.

[0206] Based on the radar module's perception of individual locations, this embodiment of the present invention divides a first sweeping area where humans are present and a second sweeping area where they are absent. This reduces the airflow force when the vertical swing blade assembly rapidly passes through the first sweeping area, while increasing it when it slowly passes through the second sweeping area. This optimizes the swing speed of the vertical guide plate within the corresponding range when the horizontal coverage area changes due to movement. This reduces the airflow force during rapid sweeps in the horizontal range corresponding to the human body, while increasing it during slow sweeps in the horizontal range outside the human body. This improves the control accuracy and efficiency of the indoor unit's air supply and optimizes the user experience.
