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 up and cooling the room, it is generally necessary for 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 most of the time 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 wind blowing directly. 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 the user's wind comfort is a technical problem that technicians in this field urgently need to solve. Summary of the invention

For example, the first object can be one or more.

[0054] It should be understood that the terms used in the present 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 plural forms.

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

[0056] Figure 1 FIG. 1 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 the 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 wind area where the target individual exists, and a second sweeping wind area where the target individual does not exist.

[0057] Wherein, the radar sensing area is an area range defined by the angle formed by the left sensing limit and the horizontal line where the radar module is located in the air-conditioning indoor unit, and the angle formed by the right sensing limit and the horizontal line where the radar module is located in the air-conditioning indoor unit. The first wind sweeping area is an area range defined by the angle formed by the left width boundary of the target individual in the horizontal direction and the horizontal line where 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 where 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 the embodiment of the present invention is that when the user activates the air conditioner, the position of the human individual relative to the air conditioner indoor unit is sensed by the radar module, 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 during the slow transition 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 with the minimum air supply speed, and then the vertical swing blade assembly gradually increases the air supply speed during the process of slowly moving away from the manned area.

[0060] The radar module is fixed in the indoor unit of the air conditioner, and the location of the indoor unit of the air conditioner is used as the origin of the radar coordinate system. The horizontal plane where the radar module is located is the XoY plane of the radar coordinate system, and the axis perpendicular to the XoY plane through the origin of the coordinate system is the Z axis. In addition, in the XoY plane, the horizontal line where the indoor unit of the air conditioner is located is the X axis, and the axis perpendicular to the X axis in the plane is the Y axis.

[0061] It can be seen that the radar sensing area includes three dimensions: the left sensing limit and the right sensing limit are distributed on the X-axis to characterize the horizontal scanning range of the radar module. The sensing limit set on the Y-axis can characterize the radiation radius of the radar module. The upper sensing limit and the lower sensing limit are distributed on the Z-axis to characterize the vertical scanning range of the radar module.

[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 overlapping 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 each 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 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 collection operations.

[0068] It should be noted that before step 101, the user needs to send an activation instruction through a 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 the working mode, the air supply control device of the air conditioner receives the sensing position information collected by the radar module in real time for each individual in its own radar sensing area, and divides the wind sweeping area based on this information:

[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, and the sensing position of the target individual is combined with the lateral width of the target individual to deduce the positions of its left width boundary and right width boundary in the horizontal direction in the radar coordinate system, and the first swept wind area is limited 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 shield 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 is used to represent the partition range of the target individual in the radar sensing area that can reflect the signal emitted by the radar module, and the second swept wind area is used to represent the partition range around the target individual that cannot reflect the signal emitted by the radar module. The embodiment of the present invention does not specifically limit the type and number of radar sensing devices in the radar module.

[0075] Exemplarily, 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 faster.

[0077] Therefore, the air supply control device of the air conditioner uses the moving angle, displacement point and other information collected by the millimeter wave radar in real time as the position information of the individual user. It can also collect information such as acceleration and speed to convert the position information of the individual user.

[0078] Exemplarily, 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 wind sweeping area and the second wind sweeping area, adjust the air supply speed and the swing speed of the vertical swing blade assembly in the rated wind swinging area.

[0080] Specifically, in step 102, the air supply control device of the air conditioner uses the angle range defined by the first air sweeping area where the target individual is located as the weakened swing wind area, and uses the angle range defined by the second air sweeping area around the target individual as the strengthened swing wind area. The relevant position information of the first air sweeping area and the second air sweeping area is packaged into the swing wind control instruction and the air supply control instruction, and sent to the indoor unit of the air conditioner together.

[0081] The air conditioner indoor unit receives and responds to the swing control instruction and the air supply control instruction, and continuously delivers air conditioning air to the outside through the fan when controlling the vertical swing blade assembly to swing back and forth in the rated swing area. According to the angle range indicated by the analyzed first sweeping area and the second sweeping area, the left and right swing speed of the vertical swing blade assembly is reduced in the enhanced swing area, and the left and right swing speed of the vertical swing blade assembly is increased in the weakened swing area. In addition, the air supply speed of the vertical swing blade assembly in any enhanced swing area is greater than or equal to the air supply speed of the vertical swing blade assembly in any weakened swing area.

[0082] The embodiment of the present invention divides the first wind sweeping area where human individuals exist and the second wind sweeping area where human individuals do not exist based on the radar module's sensed position of the individual, so as to reduce the wind force of the air supply when the vertical swing blade assembly passes through the first wind sweeping area quickly, and increase the wind force of the air supply when the vertical swing blade assembly passes through the second wind sweeping area slowly. When the horizontal coverage area of ​​the human body changes due to the movement, the swing speed of the vertical guide plate in the corresponding range is optimized, and the air conditioner reduces the wind force when the horizontal range corresponding to the human body is swept quickly, and increases the wind force when the horizontal range other than the human body is swept slowly, thereby improving the control accuracy and efficiency of the indoor unit's air supply and optimizing the user experience.

[0083] On the basis of 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 wind sweeping area and the second wind sweeping area, including: dividing n1 air supply partitions in the second wind sweeping area on the left and right sides of the first wind sweeping area respectively.

[0084] Specifically, in step 102, if the number of target individuals sensed in the radar sensing area by the air-conditioning air supply control device is 1, the angle range defined by the first wind sweeping area where the target individual is located is used as the weakened swing wind area, and the angle ranges defined by the two second wind sweeping areas separated by the radar sensing area by the target individual are used as the strengthened swing wind areas. In addition, each second wind sweeping area on the left and right sides of the target individual is divided into N1 air supply partitions.

[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 N1th gear every time it passes through an air supply partition 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 swinging speed, the air supply wind 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 1st gear every time it passes through an air supply zone until it decreases to the N1th 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 indoor unit of the air conditioner using the swing control instruction and the air supply control instruction:

[0091] When the vertical swing blade assembly swings at a lower first swing speed in the second air sweeping area on the left side of the target individual, the air supply wind speed is sequentially reduced by one gear each time it passes through an air supply partition, that is, if it rotates from the left perception limit to the left boundary of the first air sweeping area, the air supply wind speed is correspondingly reduced from the N1th gear to the 1st gear. On the contrary, if the air supply wind speed shows an increasing trend when it rotates from the left boundary of the first air sweeping area to the left perception limit, the air supply wind speed is correspondingly increased from the 1st gear to the N1th gear.

[0092] After the vertical swing blade assembly sweeps the second wind sweeping area on the left side of the target individual, the air supply wind 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 sweeps the first wind sweeping area, it returns to the lower first swing speed and swings in the second wind sweeping area on the right side of the target individual. When it swings through each wind supply partition, the wind speed of the air supply is increased by one gear in sequence, that is, if it rotates from the right boundary of the first wind sweeping area to the right perception limit, the wind speed of the air supply is correspondingly increased from the 1st gear to the N1th gear. On the contrary, if the wind speed of the air supply is decreasing when it rotates from the right perception limit to the right boundary of the first wind sweeping area, the wind speed of the air supply is correspondingly decreased from the N1th gear to the 1st gear.

[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 target individuals is 1, the angle between the left boundary of the target individual in the horizontal width and the X-axis, and the angle between the right boundary and the X-axis constitute the first wind sweeping area (recorded as [left boundary, right boundary]). Similarly, combined with the angles between the left and right perception limits of the radar module and the X-axis, the second wind sweeping area on the left side of the target individual is recorded as [left perception limit, left boundary], and the second wind sweeping area on the right side of the target individual is recorded as [right boundary, right perception limit]).

[0096] Each second air sweeping area is divided into 5 air supply zones, and the radar sensing area can be divided into 11 zones. In the process of the vertical swing blade assembly rotating from the left sensing limit to the right sensing limit, starting from the first air supply zone of [left sensing limit, left boundary], based on the air supply wind speed at the 5th gear, the lower first swing speed is used to reduce one gear each time a air supply zone is passed, until the air supply wind speed is reduced to the 1st gear in the last air supply zone of [left sensing limit, left boundary]. Subsequently, after crossing the left 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 wind speed is maintained at the 1st gear to sweep the first air sweeping area from left to right. Immediately thereafter, starting from the first air supply zone of [right boundary, right sensing limit], based on the air supply wind speed at the 1st gear, the lower first swing speed is used to increase one gear each time a air supply zone is passed, until the air supply wind speed is increased to the 5th gear in the last air supply zone of [right boundary, right sensing limit].

[0097] Similarly, in the process of the vertical swing blade assembly rotating from the right perception limit to the left perception limit, starting from the last air supply zone of [right boundary, right perception limit], based on the air supply wind speed at the 5th gear, the lower first swing speed is used to reduce the wind speed by one gear each time a air supply zone is passed, until the air supply wind speed is reduced to the 1st gear at the first air supply zone of [right boundary, right perception 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 wind speed is maintained at the 1st gear to sweep the first air sweeping area from right to left. Immediately thereafter, starting from the last air supply zone of [left perception limit, left boundary], based on the air supply wind speed at the 1st gear, the lower first swing speed is used to increase the wind speed by one gear each time a air supply zone is passed, until the air supply wind speed is reduced to the 5th gear at the first air supply zone of [left perception limit, left boundary].

[0098] When only one human individual is sensed within the sensing range, the embodiment of the present invention divides the second air sweeping area where no human individual exists into regions, and sets different air supply speeds for the divided regions in order, so that the air supply wind force is gradually weakened when the vertical swing blade assembly slowly approaches the first air sweeping area in the second air sweeping area, and the air supply wind force is gradually increased when the vertical swing blade assembly slowly moves away from the first air sweeping area in the second air sweeping area. The swing speed of the vertical guide plate in the corresponding range is optimally controlled, and the air conditioner is made to weaken the wind force when the air is swept quickly in the horizontal range corresponding to the human body, and gradually weaken the wind force when it slowly approaches the human body in the non-human horizontal range, and gradually increase the wind force when it slowly moves away from the human body, thereby improving the control accuracy and efficiency of the air supply of the indoor unit and optimizing the user's experience of being blown away by the wind.

[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 respectively, 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 in the radar sensing area is k, the air supply control device of the air conditioner uses the angle range defined by the first wind sweeping area where the target individuals are located as k weakened swing wind areas, and the angle range defined by the second wind sweeping area separated by the radar sensing area by the k target individuals is used as k+1 strengthened swing wind areas. In addition, N2 air supply partitions are respectively divided in the first second wind sweeping area and the k+1 second wind sweeping area on the left and right sides of the radar sensing area, and 2N2 air supply partitions are also divided in the remaining second wind sweeping areas sandwiched between any two target individuals, so that they include the unmanned area on the right side of the previous target individual and the unmanned area on the left side of the next target individual.

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

[0102] In 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 swinging 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 wind 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, while controlling the vertical swing blade assembly to rotate counterclockwise at the fourth swing speed, the air supply wind 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 wind sweeping areas except the 1st second wind sweeping area and the k+1th second wind sweeping 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 wind speed is increased by one gear each time passing through an air supply zone 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 passing through an air supply zone until it increases from the N2th gear to the 1st gear.

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

[0109] Specifically, when the vertical swing blade assembly is swinging back and forth in 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 when controlling 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 in the first second air sweeping area at a lower first swinging speed, the air supply wind speed is sequentially reduced by one gear each time it passes through an air supply partition, that is, if it rotates from the left sensing limit to the right boundary of the second air sweeping area, the air supply wind speed is correspondingly reduced from the N2th gear to the 1st gear. On the contrary, if the air supply wind speed shows an increasing trend when it rotates from the right boundary of the second air sweeping area to the left sensing limit, the air supply wind speed is correspondingly increased from the 1st gear to the N2th gear.

[0111] After the vertical swing blade assembly sweeps the first second wind sweeping area, the air supply wind 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 first wind sweeping zone at a higher second swing speed.

[0112] Next, after the vertical swing blade assembly sweeps 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 wind speed is increased by one gear each time it passes through an air supply partition in the unmanned area on the right side of the first target individual, the air supply wind speed is reduced by one gear each time it passes through an air supply partition in the unmanned 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 wind 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 wind speed is increased from the N2th gear to the 1st gear. On the contrary, if it rotates from the right boundary to the left boundary of the second first wind sweeping area, the air supply wind speed is increased first and then decreased.

[0113] After the vertical swing blade assembly sweeps the second second wind sweeping area, the air supply wind 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 second first wind sweeping zone at a higher second swing speed.

[0114] Repeat multiple rounds until the vertical swing blade assembly swings at a lower first swing speed in the k+1th second air sweeping area, and the air supply wind speed is increased by one gear in sequence each time it passes through an air supply partition, that is, if it rotates from the right boundary of the k+1th second air sweeping area to the right perception limit, the air supply wind speed is correspondingly increased from the 1st gear to the N2th gear. On the contrary, if the air supply wind speed shows a decreasing trend when it rotates from the right perception limit to the right boundary of the k+1th second air sweeping area, the air supply wind speed is correspondingly increased from the N2th gear to the 1st gear.

[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 the 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 a number of target individuals being 2 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 and the X-axis in the horizontal width constitute the first wind sweeping area (recorded as [left boundary 1, right boundary 1]). Similarly, the first wind sweeping area where the second target individual is located is recorded 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 target individual and the second target individual 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 second air sweeping area and the third second air sweeping area are divided into 5 air supply zones respectively, and the second second air sweeping area is divided into 9 air supply zones. At this time, the radar sensing area can be divided into 21 zones. In the process of the vertical swing blade assembly rotating from the left sensing limit to the right sensing limit, starting from the first air supply zone of [left sensing limit, left boundary 1], based on the air supply wind speed of the 5th gear, the lower first swing speed is used to reduce one gear each time an air supply zone is passed, until the air supply wind speed is reduced to the 1st gear in the last air supply zone of [left sensing limit, left boundary 1]. Subsequently, after crossing the 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 air supply wind speed is maintained at the 1st gear to sweep through the first first air sweeping area 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 to sweep through the second first wind 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 an 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, in the process of the vertical swing blade assembly rotating from the right sensing limit to the left sensing limit, the reverse adjustment of the above process can be performed, which will not be elaborated here.

[0122] When the embodiment of the present invention senses only multiple human individuals within the sensing range, the second air sweeping areas with different distributions are divided into different areas, and different air supply speeds are set for the divided different areas in order, so that the vertical swing blade assembly gradually increases the air supply wind force when it slowly moves away from the first air sweeping area where the first target individual is located between two adjacent target individuals, and then gradually weakens the air supply wind force when it slowly approaches the first air sweeping area where the second target individual is located. The swing speed of the vertical guide plate within the corresponding range is optimally controlled, and the air conditioner weakens the wind force when it quickly sweeps the air in the horizontal range corresponding to the human body, and gradually weakens the wind force when it slowly approaches the human body in the non-human horizontal range, and gradually strengthens the wind force when it slowly moves 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 1st second wind sweeping area and the k+1th second wind sweeping area into N2 air supply zones respectively, and dividing the other second wind sweeping areas except the 1st 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 sensed 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 the two adjacent target individuals in the radar coordinate system as the relative distance between the two.

[0127] For example, the azimuth angles formed by the lines connecting two adjacent target individuals and the origin of the radar coordinate system and the X-axis can be directly subtracted, and the azimuth angle difference between the two can be 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 supply control device of the air conditioner performs cluster analysis according to the relative distance between any two adjacent target individuals, regards the clusters formed by the target individuals with a relatively close relative distance as a whole, and updates the number of target individuals k using the cluster number of the cluster. At the same time, the first sweeping wind area is defined according to the angle range occupied by the cluster in the radar coordinate system, and the division of the second sweeping wind area is further analyzed in combination with the cluster number of the cluster:

[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 unmanned area and execute the corresponding control process.

[0133] When the embodiment of the present invention senses only multiple human individuals within the sensing range, clustering is performed according to the distribution position of the target individuals, and individuals at a relatively close distance are regarded as a whole, and then the second air sweeping areas with different distributions are divided into different areas, and different air supply speeds are set in order according to the different partitions. It can reduce unnecessary control, improve the control accuracy and efficiency of the indoor unit air supply, and optimize the user's experience of wind protection.

[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 a cooling mode, determining the first execution position through the first azimuth angle collected by the radar module for 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 range of the horizontal swing blade assembly according to the working mode activated by the air conditioner in addition to adjusting the swing speed of the vertical swing blade assembly and the air supply speed of the air conditioner, in the following specific manner:

[0137] When the air supply control device of the air conditioner determines that the activated working mode of the air conditioner is the cooling mode according to 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 longitudinal height of the target individual by the radar module and the mapping relationship between the height range and the execution angle.

[0138] The first azimuth angle refers to the angle formed by the line connecting the foot of a target individual in the room and the origin of the coordinate system and the XoY plane. The first azimuth angle is used to characterize 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 horizontal 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 range of the swing blade assembly.

[0141] Specifically, when the air supply control device of the air conditioner determines that the vertical swing blade assembly enters the first wind sweeping area to sweep the air left and right according to the operating state of the vertical swing blade assembly, the horizontal swing blade assembly is controlled to swing up and down between the first execution position and the lower limit position. Once the vertical swing blade assembly leaves the first wind sweeping area, the horizontal swing blade assembly is restored to swing up and down between the upper boundary and the lower boundary in its own rated wind swinging range.

[0142] In the cooling mode, the embodiment of the present invention determines the first execution position according to the foot sensing position scanned by the radar on the module target individual, and updates the first execution position to the upper boundary of the swinging wind range of the horizontal swing leaf assembly, so that when the vertical swing leaf assembly quickly passes through the first sweeping wind area and weakens the wind force of the cold wind, the horizontal swing leaf assembly is also controlled to sweep the wind within the range below the human foot. When the vertical swing leaf assembly is aimed at the person, the cold air flow can be sunk by changing the swinging wind range of the horizontal swing leaf assembly, so as to achieve cooling without blowing the soles of the feet and optimize the user experience.

[0143] On the basis of any of the above embodiments, after adjusting the air supply wind speed and the swing speed of the vertical swing blade assembly within the rated swing wind area based on the first sweeping wind area and the second sweeping wind area, it also includes: when it is determined that the working mode is a heating mode, determining the second execution position through the second azimuth angle collected by the radar module for 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 range of the horizontal swing blade assembly according to the working mode activated by the air conditioner in addition to adjusting the swing speed of the vertical swing blade assembly and the air supply speed of the air conditioner, in the following specific manner:

[0146] When the air supply control device of the air conditioner determines that the activated working mode of the air conditioner is the heating mode according to 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 longitudinal height of the target individual by the radar module and the mapping relationship between the height range and the execution angle.

[0147] The second azimuth angle refers to the angle formed by the line connecting the head of a target individual in the room and the origin of the coordinate system and the XoY plane. The second azimuth angle is used to characterize 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 horizontal 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 wind swing range of the swing blade assembly.

[0150] Specifically, when the air supply control device of the air conditioner determines that the vertical swing blade assembly enters the first wind sweeping area to sweep the air left and right according to the operating state of the vertical swing blade assembly, the horizontal swing blade assembly is controlled to swing up and down between the upper limit position and the second execution position. Once the vertical swing blade assembly leaves the first wind sweeping area, the horizontal swing blade assembly is restored to swing up and down between the upper boundary and the lower boundary in its own rated wind swinging 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 lateral angle span α and automatically shield the human individual that 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 five 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. Among them, 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 wind speed is set to 5, 4, 3, 2, and 1 accordingly. Moreover, the air supply wind speed of the manned area α where the target individual is located is 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 angle of the target person's feet, 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 to prevent the hot air from blowing over the head.

[0160] In the heating mode, the embodiment of the present invention determines the second execution position according to the head sensing position scanned by the radar on the module target individual, and updates the second execution position to the lower boundary of the swinging wind range of the horizontal swing blade assembly, so that when the vertical swing blade assembly quickly passes through the first sweeping wind area and weakens the wind force of the hot air, the horizontal swing blade assembly is also controlled to sweep the wind within the range above the human head. When the vertical swing blade assembly is aimed at the person, the hot air flow can be floated downward by changing the swinging wind range of the horizontal swing blade assembly, so that heating can be passed over the head, 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 of the air conditioner provided in 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 it is determined by the radar module 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 wind speed and the swing speed of the vertical swing blade assembly in the rated swing wind area based on the first sweep wind area and the second sweep wind area.

[0164] Wherein, the radar sensing area is an area range defined by the angle formed by the left sensing limit and the horizontal line where the radar module is located in the air-conditioning indoor unit, and the angle formed by the right sensing limit and the horizontal line where the radar module is located in the air-conditioning indoor unit. The first wind sweeping area is an area range defined by the angle formed by the left width boundary of the target individual in the horizontal direction and the horizontal line where 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 where 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 individual in its own radar sensing area, and divides the wind sweeping area based on the information:

[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, and the sensing position of the target individual is combined with the lateral width of the target individual to deduce the positions of its left width boundary and right width boundary in the horizontal direction in the radar coordinate system, and the first swept wind area is limited 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 shield 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 angle range defined by the first air sweeping area where the target individual is located as the weakened swing air area, and uses the angle range defined by the second air sweeping area around the target individual as the strengthened swing air area. The relevant position information of the first air sweeping area and the second air sweeping area is packaged into the swing air control instruction and the air supply control instruction, and sent together to the air conditioner indoor unit.

[0170] The air conditioner indoor unit receives and responds to the swing control instruction and the air supply control instruction, and continuously delivers air conditioning air to the outside through the fan when controlling the vertical swing blade assembly to swing back and forth in the rated swing area. According to the angle range indicated by the analyzed first sweeping area and the second sweeping area, the left and right swing speed of the vertical swing blade assembly is reduced in the enhanced swing area, and the left and right swing speed of the vertical swing blade assembly is increased in the weakened swing area. In addition, the air supply speed of the vertical swing blade assembly in any enhanced swing area is greater than or equal to the air supply speed of the vertical swing blade assembly in any weakened swing area.

[0171] Optionally, the air supply control module 520 includes a first air supply division 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 N1 air supply partitions in the second air sweeping areas located on the left and right sides of the first air sweeping area.

[0173] The first control unit is used for reducing the air supply speed from the N1th gear by one gear each time passing through an air supply partition 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 for increasing the air supply speed from the first gear by one gear each time passing through an air supply zone during the process in which the vertical swing blade assembly rotates from the right boundary of the first wind sweeping area to the right perception limit at the first swinging speed until it decreases to the N1th 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 divides 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 blade acquisition unit is used to acquire the current position of the vertical swing blade assembly during the process of the vertical swing blade assembly sensing the area of ​​the radar.

[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 wind 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, while controlling the vertical swing blade assembly to rotate counterclockwise at the fourth swing speed, the air supply wind 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 wind sweeping areas except the 1st second wind sweeping area and the k+1th second wind sweeping 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 wind speed is increased by one gear each time passing through an air supply zone 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 passing through an air supply zone until it increases from the N2th gear to the 1st gear.

[0185] Among them, the third swing speed is greater than the second swing speed; the value of k is a positive integer greater than 1.

[0186] Optionally, the device further comprises 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 to 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 wind 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 on 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 a first execution position and a lower limit position when it is determined that the vertical swing blade assembly is in a 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 wind 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 a second execution position and an 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 human head of the target individual relative to the radar module; the upper limit position is the upper boundary of the rated swing wind range of the swing blade assembly.
