[0002] With the advancement of technology, more and more products have a higher degree of automation, making them cover a wider range of scenarios and easier to operate; people are also increasingly favoring more intelligent products in their daily lives, especially air conditioners.

[0003] Smart air conditioners are primarily controlled by user voice commands. However, current smart air conditioners often have a discrepancy between the airflow direction and the user's desired direction, which reduces the user experience. Therefore, providing an air conditioner with more accurate airflow is essential. Summary of the Invention

[0004] The present invention aims to solve at least one of the above-mentioned technical problems.

[0005] Therefore, the first objective of this invention is to provide a control method for an air conditioner.

[0007] A third objective of this invention is to provide an air conditioner.

[0008] To achieve the objectives of this invention, this invention provides a control method for an air conditioner, comprising: acquiring a first voice command; and analyzing the first sound source direction angle A of the first voice command. 声源1 ; Adjust the direction angle A of the first sound source 声源1 With critical angle A 临界 Compare; based on the comparison results and the first sound source direction angle A 声源1 Control the angle of rotation of the air sweeper blades in the air conditioner.

[0009] Compared with existing technologies, the technical effects achieved by this technical solution are as follows: This invention acquires a first voice command and analyzes its first sound source direction angle A. 声源1 By comparing it with the critical angle A 临界 By comparing and determining its location, the rotation angle of the air conditioner's sweeping blades is controlled, and the critical angle A is used as the reference. 临界 The effective usage area of ​​the air conditioner can be simply divided into two zones. User commands can be easily executed by determining the user's location and controlling the rotation angle of the air sweeping blades using only voice commands, via the direction angle A of the first sound source. 声源1By directly controlling the rotation angle of the air sweeping blades, the blades can be turned directly towards or away from the location of the person, which not only improves the accuracy of the air conditioner's airflow but also enhances the user experience.

[0010] In the above technical solution, based on the comparison results and the first sound source direction angle A 声源1 Controlling the rotation angle of the air conditioner's sweeping blades includes: acquiring the content of the first voice command; based on the content of the first voice command, the comparison result, and the first sound source direction angle A... 声源1 Control the angle of rotation of the air sweeper blades in the air conditioner.

[0011] Compared with existing technologies, the technical effects achieved by this solution are as follows: the content of the voice command is the operation that the user expects the air conditioner to perform; the user's needs can be obtained by analyzing the content of the voice command; and the results of the comparison are obtained by analyzing the content of the first voice command and the direction angle A of the first sound source. 声源1 This method controls the rotation angle of the air sweeper blades in the air conditioner. The control method is simple, easy to meet user needs, and can achieve good results.

[0012] In any of the above technical solutions, if the content of the first voice command is "blowing wind towards a person", then based on the comparison result and the first sound source direction angle A... 声源1 The angle of rotation of the air sweeper blades of the air conditioner includes: if the angle A is in the direction of the first sound source 声源1 Less than or equal to the critical angle A 临界 Determine the first angle B1, and control the rotation of the sweeping blades based on the first angle B1. The first angle B1 is obtained by the following formula: B1 = A 声源1 -y; and / or if the first sound source direction angle A 声源1 greater than the critical angle A 临界 Determine the second angle B2, and control the rotation of the sweeping blades based on the second angle B2. The second angle B2 is obtained by the following formula: B2 = A 声源1 -y+m; where y is the limiting angle of the sweeping blades and m is the correction angle.

[0013] Compared with existing technologies, the technical effects achieved by this solution are as follows: When the user's requirement is to blow air towards a person, since the rotation angle varies in different areas, it is necessary to determine the first sound source direction angle A. 声源1 This allows the system to determine the area where the first voice command is located, which is also the area where the user is located. Based on the corresponding rotation angle of the user's area, the system controls the rotation of the sweeping blades, further improving the user experience.

[0014] In any of the above technical solutions, controlling the rotation of the sweeping blades according to the first angle B1 includes: if the first angle B1 is less than or equal to the leftmost angle A of the sweeping blades... L Control the air sweeping blades to rotate to the leftmost angle AL Position; if the first angle B1 is greater than the leftmost angle A of the sweeping blades L Controlling the rotation of the sweeping blades according to a first angle B1; and / or controlling the rotation of the sweeping blades according to a second angle B2 includes: if the second angle B2 is greater than or equal to the rightmost angle A of the sweeping blades. R Control the air sweeper blades to rotate to the rightmost angle A. R Position; if the rotation angle B2 is less than the rightmost angle A R Control the sweeping blades to rotate at the second angle B2.

[0015] Compared with existing technologies, the technical effects achieved by this solution are as follows: When the user is in the left zone, the rotation of the sweeping blades is controlled according to the first angle B1. If the first angle B1 is greater than the leftmost angle A of the sweeping blades... L The first angle B1 is the target angle of the sweeping blades. Simply rotate the sweeping blades to the first angle B1. If the first angle B1 is less than or equal to the leftmost angle A of the sweeping blades... L Because the sweeping blades can only rotate to the leftmost angle A. L At this point, control the sweeping blades to rotate to the leftmost angle A. L Position is sufficient; when the user is in the right zone, the rotation of the sweeping blades is controlled according to the second angle B2. If the second angle B... 2小 At the rightmost angle A of the sweeping blades R The second angle B2 is the target angle of the sweeping blades. Simply rotate the sweeping blades to the second angle B2. If the second angle B2 is less than or equal to the rightmost angle A of the sweeping blades... R Because the sweeping blades can only rotate to the far right angle A R At this point, control the sweeping blades to rotate to the rightmost angle A. R Location is sufficient.

[0016] In any of the above technical solutions, the control method further includes: acquiring a second voice command; analyzing the second sound source direction angle A of the second voice command. 声源2 Obtain the first sound source direction angle A 声源1 Angle A with respect to the direction of the second sound source 声源2 The absolute value of the difference between them |ΔA 声源1-声源2 |;The absolute value of the difference|ΔA 声源1-声源2 | Compare with the hysteresis angle x; control the rotation of the sweeping blades or prevent them from rotating based on the comparison result.

[0017] Compared with existing technologies, the technical effect achieved by this technical solution is as follows: When the user issues a second voice command to blow air towards the person, a backlash angle x is set, which is achieved by adjusting the first sound source direction angle A. 声源1 Angle A with respect to the direction of the second sound source 声源2The absolute value of the difference between them |ΔA 声源1-声源2 | By comparing with the hysteresis angle x, the rotation of the sweeping blades can be controlled, which can prevent the sweeping blades from swinging back and forth frequently when the user issues voice commands while moving within a small range.

[0018] In any of the above technical solutions, controlling the rotation or non-rotation of the sweeping blades based on the comparison result includes: if the absolute value of the difference is |ΔA 声源1-声源2 |If the difference is less than or equal to the hysteresis angle x, control the sweeping blades to not rotate; and / or if the absolute value of the difference is |ΔA| 声源1-声源2 |When the hysteresis angle x is greater than the hysteresis angle x, control the rotation of the sweeping blades.

[0019] Compared with existing technologies, the technical effects achieved by this technical solution are: if the absolute value of the difference |ΔA 声源1-声源2 |If the difference is less than or equal to the hysteresis angle x, meaning the user moves within a small range, the airflow can still be directed towards the person even if the sweeping blades do not rotate; if the absolute value of the difference is |ΔA| 声源1-声源2 When the hysteresis angle x is greater than the hysteresis angle x, the user's movement range is larger. The air sweeping blades are controlled to rotate to the user's position, thereby realizing the user's command and further improving the intelligence of the air conditioner.

[0020] In any of the above technical solutions, if the content of the first voice command is "avoid people and let the wind blow," then based on the comparison result and the first sound source direction angle A... 声源1 The angle of rotation of the air sweeper blades of the air conditioner includes: if the angle A is in the direction of the first sound source 声源1 Less than or equal to the critical angle A 临界 Control the sweeping blades to rotate to the rightmost angle A R Location; and / or if the direction angle A of the first sound source 声源1 greater than the critical angle A 临界 Control the air sweeping blades to rotate to the leftmost angle A L Location.

[0021] Compared with existing technologies, the technical effect achieved by this technical solution is as follows: When the content of the first voice command is "avoid people and let the wind blow," the effect is achieved according to the direction angle A of the first sound source. 声源1 and critical angle A 临界 By determining the area where the user is located, the air sweeper blades can be turned to the extreme position of another area to avoid blowing air to people. The control method is simple; the user's needs can be met simply by turning the air sweeper blades to the extreme position of an area other than the user's.

[0022] In any of the above technical solutions, the control method further includes: acquiring a third voice command; analyzing the direction angle A of the third sound source of the third voice command. 声源3 Determine the direction angle A of the third sound source. 声源3 Is it in (A) 临界 -z, A临界 Within the range of +z]; based on the judgment result and the position of the sweeping blades, control the sweeping blades to rotate to their limit positions or not to rotate; where z is the stationary angle of the sweeping blades; the limit positions include the leftmost angle A. L Position and rightmost angle A R Location.

[0023] Compared with existing technologies, the technical effect achieved by this solution is as follows: When a user issues a second, more direct airflow command (i.e., a third voice command) while facing the air conditioner, the direction angle A of the third sound source is determined. 声源3 Is it in (A) 临界 -z, A 临界 Within the range of +z], by introducing a stationary angle z, the sweeping blades are prevented from frequently swinging back and forth between the far left and far right when the user moves a small distance in the center position.

[0024] In any of the above technical solutions, if the direction angle A of the third sound source 声源3 In (A) 临界 -z, A 临界 Within the range of +z], controlling the rotation of the sweeping blades to their limit position or preventing them from rotating based on the judgment result includes: if the angle A of the direction of the third sound source is... 声源3 In (A) 临界 -z, A 临界 Within the range, and with the sweeping blades at their limit positions, control the sweeping blades to not rotate; and / or if the direction angle A of the third sound source... 声源3 In (A) 临界 -z, A 临界 Within the specified range, and with the sweeping blades not in their extreme positions, control the sweeping blades to rotate to the rightmost angle A. R Location; and / or if the direction angle A of the third sound source 声源3 In (A) 临界 A 临界 Within the range of +z], and with the sweeping blades at their extreme positions, control the sweeping blades to not rotate; and / or if the direction angle A of the third sound source is... 声源3 In (A) 临界 A 临界 Within the range of +z], and with the sweeping blades at their extreme positions, control the sweeping blades to rotate to the leftmost angle A. L Location.

[0025] Compared with existing technologies, the technical effects achieved by adopting this technical solution are: when the user is in (A) 临界 -z, A 临界 Within the specified range, if the air conditioner's sweeping blades are at any extreme position, the blades will not rotate, yet the user will still be protected from direct drafts, thus achieving the "avoid drafts" instruction. If the air conditioner's sweeping blades are not at their extreme positions, since the user's position is slightly to the left of the center of the air conditioner, the sweeping blades will be controlled to rotate to the rightmost angle A.R Location allows for better avoidance of people when receiving airflow; when the user is in (A) 临界 A 临界 Within the range of +z], if the air conditioner's sweeping blades are at any extreme position, the sweeping blades will not rotate, yet the user will still be protected from direct drafts, thus achieving the "avoid drafts" instruction. If the air conditioner's sweeping blades are not at their extreme positions, since the user's position is slightly to the right of the center of the air conditioner, the sweeping blades will be controlled to rotate to the leftmost angle A. L The location allows for better protection from drafts and people.

[0026] In any of the above technical solutions, if the direction angle A of the third sound source 声源3 Not in (A) 临界 -z, A 临界 Within the range of +z], controlling the rotation of the sweeping blades to their limit position or not to rotate based on the judgment result also includes: if the angle A of the direction of the third sound source 声源3 Less than or equal to A 临界 -z controls the rotation of the sweeping blades to the rightmost angle A. R Location; and / or if the direction angle A of the third sound source 声源3 Greater than A 临界 +z, control the sweeping blades to rotate to the leftmost angle A. L Location.

[0027] Compared with existing technologies, the technical effects achieved by this technical solution are as follows: if the direction angle A of the third sound source... 声源3 Not in (A) 临界 -z, A 临界 Within the range of +z], the angle A of the direction of the third sound source 声源3 Less than or equal to A 临界 -z indicates that the user is in the left zone, and the sweeping blades are controlled to rotate to the rightmost angle A. R Location; Angle A of the direction of the third sound source 声源3 Greater than A 临界 +z indicates that the user is in the right zone, and the sweeping blades are rotated to the leftmost angle A. L Location can better prevent people from being exposed to drafts, further improving the user experience.

The acquisition module acquires the first voice command, and the analysis module analyzes the first sound source direction angle A of the first voice command. 声源1 The comparison module determines the area where the sound source is located and transmits this information to the control module. The control module then controls the rotation angle of the air conditioner's air sweeper blades to meet the user's needs. Through the cooperation of each module, the air conditioner can be controlled effectively.

[0030] To achieve the third objective of this invention, this invention provides an air conditioner, which includes: a processor, a memory, and a program or instructions stored in the memory and executable on the processor.

It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0042] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and therefore the scope of protection of the invention is not limited to the specific embodiments disclosed below.

[0043] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the following description is provided in conjunction with... Figures 1 to 2 Specific embodiments of the present invention will be described in detail below.

[0044]

Example 1

[0045] like Figure 1 As shown, the present invention provides a control method for an air conditioner, comprising:

[0046] S100, Obtain the first voice command;

[0047] S200, Analyze the first sound source direction angle A of the first voice command. 声源1 ;

[0048] S300, Adjust the first sound source direction angle A 声源1 With critical angle A 临界 Compare;

[0049] S400, Based on the comparison results and the first sound source direction angle A 声源1 Control the angle of rotation of the air sweeper blades in the air conditioner.

[0050] In related technologies, the air delivery direction of smart air conditioners often differs from the user's expected direction, resulting in a poor user experience. Therefore, embodiments of the present invention provide a control method for an air conditioner, which acquires a first voice command and analyzes its first sound source direction angle A.声源1 By comparing it with the critical angle A 临界 The system compares and determines the area in which the air conditioner is located, thereby controlling the angle of rotation of the air sweeper blades.

[0051] Specifically, through the critical angle A 临界 The effective usage area of ​​an air conditioner can be simply divided into two zones, by measuring the angle A of the first sound source. 声源1 With critical angle A 临界 By comparing the data, the area where the first voice command is located can be determined, i.e., the area where the user is located. Then, based on the direction angle A of the first sound source... 声源1 By controlling the angle of the air sweeper blades, the blades can be turned directly to the user's location, which not only improves the accuracy of the airflow towards or away from the person, but also enhances the user experience.

[0052] Preferably, the critical angle A 临界 The preferred angle is 90°, which divides the effective use area of ​​the air conditioner into two zones: the left zone and the right zone. By determining whether a person is in the left or right zone, the rotation angle of the air sweeping blades can be better controlled, providing users with a better user experience.

[0053] In some embodiments of the present invention, based on the comparison result and the first sound source direction angle A 声源1 Controlling the rotation angle of the air conditioner's sweeping blades includes: acquiring the content of the first voice command; based on the content of the first voice command, the comparison result, and the first sound source direction angle A... 声源1 Control the angle of rotation of the air sweeper blades in the air conditioner.

[0054] Preferably, the content of the voice command is the operation that the user expects the air conditioner to perform. By analyzing the content of the voice command, the user's needs can be obtained. This is achieved by combining the content of the first voice command, the comparison result, and the first sound source direction angle A. 声源1 This method controls the rotation angle of the air sweeper blades in the air conditioner. The control method is simple, easy to meet user needs, and can achieve good results.

[0055] In some embodiments of the present invention, if the content of the first voice command is "blowing wind toward a person", the comparison result and the first sound source direction angle A are used to determine the correct direction. 声源1 The angle of rotation of the air sweeper blades of the air conditioner includes: if the angle A is in the direction of the first sound source 声源1 Less than or equal to the critical angle A 临界 Determine the first angle B1, and control the rotation of the sweeping blades based on the first angle B1. The first angle B1 is obtained by the following formula: B1 = A 声源1 -y; and / or if the first sound source direction angle A 声源1 greater than the critical angle A 临界Determine the second angle B2, and control the rotation of the sweeping blades based on the second angle B2. The second angle B2 is obtained by the following formula: B2 = A 声源1 -y+m; where y is the limiting angle of the sweeping blades and m is the correction angle.

[0056] Preferably, when the user's requirement is to blow air towards a person, since the rotation angle is different in different areas, it is necessary to determine the first sound source direction angle A. 声源1 This allows the system to determine the area where the first voice command is located, which is also the area where the user is located. Based on the corresponding rotation angle of the user's area, the system controls the rotation of the sweeping blades, further improving the user experience.

[0057] Preferably, through the critical angle A 临界 The effective operating area of ​​the air conditioner is divided into a left zone and a right zone. For a person, the leftmost direction is 0°, while for the air sweeper blades, the leftmost direction is y. Therefore, the first angle B1 in the left zone is A. 声源1 -y, the value of y depends on the actual situation and specific model; because the air outlet of the air conditioner is affected by the air duct profile, the left and right air fields are asymmetrical. When the user is in the right zone and the requirement is for the air to blow towards them, the airflow will often be biased to the left, resulting in the inability to achieve direct airflow towards them or a poor user experience. Therefore, a correction angle m is set so that the second angle B2 in the right zone is equal to A. 声源1 -y+m corrects the issue of the wind being biased to the left, improving the user's experience of the wind blowing towards people when in the right zone. The value of m can be adjusted according to the model and actual usage.

[0058] Preferably, when blowing air towards a person, the air guide plate should be rotated to the most favorable airflow position to ensure maximum airflow. The air guide plate is preferably in a horizontal position, which is the position with the largest airflow area.

[0059] In some embodiments of the present invention, controlling the rotation of the sweeping blades according to the first angle B1 includes: if the first angle B1 is less than or equal to the leftmost angle A of the sweeping blades... L Control the air sweeping blades to rotate to the leftmost angle A L Position; if the first angle B1 is greater than the leftmost angle A of the sweeping blades L Controlling the rotation of the sweeping blades according to a first angle B1; and / or controlling the rotation of the sweeping blades according to a second angle B2 includes: if the second angle B2 is greater than or equal to the rightmost angle A of the sweeping blades. R Control the sweeping blades to rotate to the rightmost angle A R Position; if the rotation angle B2 is less than the rightmost angle A R Control the sweeping blades to rotate at the second angle B2.

[0060] Preferably, when the user is in the left zone, the rotation of the sweeping blades is controlled according to the first angle B1. If the first angle B1 is greater than the leftmost angle A of the sweeping blades... L The first angle B1 is the target angle of the sweeping blade. The sweeping blade is rotated to the first angle B1 by controlling the sweeping blade motor. If the first angle B1 is less than or equal to the leftmost angle A of the sweeping blade... L Because the sweeping blades can only rotate to the leftmost angle A. L At this point, control the sweeping blades to rotate to the leftmost angle A. L Location is sufficient.

[0061] Preferably, when the user is in the right zone, the rotation of the sweeping blades is controlled according to the second angle B2. If the second angle B2... 2小 At the rightmost angle A of the sweeping blades R The second angle B2 is the target angle of the sweeping blades. The sweeping blades are rotated to the second angle B2 by controlling the sweeping blade motor. If the second angle B2 is less than or equal to the rightmost angle A of the sweeping blades... R Because the sweeping blades can only rotate to the far right angle A R At this point, control the sweeping blades to rotate to the rightmost angle A. R Location is sufficient.

[0062] In some embodiments of the present invention, the control method further includes: acquiring a second voice command; and analyzing the second sound source direction angle A of the second voice command. 声源2 Obtain the first sound source direction angle A 声源1 Angle A with respect to the direction of the second sound source 声源2 The absolute value of the difference between them |ΔA 声源1-声源2 |;The absolute value of the difference|ΔA 声源1-声源2 | Compare with the hysteresis angle x; control the rotation of the sweeping blades to remain stationary based on the comparison result.

[0063] Preferably, when the user issues a second voice command to blow air towards the person, a backlash angle x is set, preferably (0°, 5°). This backlash angle x is determined by the first sound source direction angle A. 声源1 Angle A with respect to the direction of the second sound source 声源2 The absolute value of the difference between them |ΔA 声源1-声源2 | By comparing with the hysteresis angle x, the rotation of the sweeping blades can be controlled, which can prevent the sweeping blades from swinging back and forth frequently when the user issues voice commands while moving within a small range.

[0064] In some embodiments of the present invention, controlling the rotation or non-rotation of the sweeping blades based on the comparison result includes: if the absolute value of the difference is |ΔA| 声源1-声源2|If the difference is less than or equal to the hysteresis angle x, control the sweeping blades to not rotate; and / or if the absolute value of the difference is |ΔA| 声源1-声源2 |When the hysteresis angle x is greater than the hysteresis angle x, control the rotation of the sweeping blades.

[0065] Preferably, if the absolute value of the difference is |ΔA 声源1-声源2 | If the hysteresis angle is less than or equal to x, it means that the user is moving within a small range. At this time, the air sweeping blades can still blow air towards the person without rotating, thus avoiding frequent back-and-forth swinging of the air sweeping blades.

[0066] Preferably, if the absolute value of the difference is |ΔA 声源1-声源2 When the hysteresis angle x is greater than the user's movement range, if the air sweeping blades are not rotated, the air cannot continue to blow air towards the user. Therefore, the air sweeping blades are controlled to rotate to the user's position to realize the user's command and further improve the intelligence of the air conditioner.

[0067] In some embodiments of the present invention, if the content of the first voice command is "avoid people and let the wind blow," the comparison result and the first sound source direction angle A are used to determine the correct command. 声源1 The angle of rotation of the air sweeper blades of the air conditioner includes: if the angle A is in the direction of the first sound source 声源1 Less than or equal to the critical angle A 临界 Control the air sweeper blades to rotate to the rightmost angle A. R Location; and / or if the direction angle A of the first sound source 声源1 greater than the critical angle A 临界 Control the air sweeping blades to rotate to the leftmost angle A L Location.

[0068] Preferably, when the content of the first voice command is "avoid people and let the wind blow," the direction angle A of the first sound source is used as the basis for the command. 声源1 and critical angle A 临界 Determine the user's location, i.e., whether the user is in the left or right zone. When the user is in the left zone, control the sweeping blades to turn to the rightmost angle A. R Position: When the user is in the right zone, control the sweeping blades to turn to the leftmost angle A. L Location can fulfill user needs.

[0069] Preferably, when avoiding direct airflow to people, the air deflector should also be rotated to a suitable area. In heating mode, the air deflector should be rotated to a lower position. Since hot air has a lower density, the hot air will rise after being blown out. If the air conditioner's parameters are reasonable, the hot air can fall to the ground, maximizing heat exchange in all areas of the target space and improving the user experience. The rotation angle of the air deflector should be set according to the specific model.

[0070] Preferably, when the airflow is directed away from people and in cooling mode, the air deflector is rotated to a slightly higher position. Since the cold air has a higher density, the cold air will sink after being blown out, which can ensure the maximum heat exchange between the air outlet and the ambient space, thus ensuring the best user experience.

[0071] In some embodiments of the present invention, the control method further includes: acquiring a third voice command; and analyzing the third sound source direction angle A of the third voice command. 声源3 Determine the direction angle A of the third sound source. 声源3 Is it in (A) 临界 -z, A 临界 Within the range of +z]; based on the judgment result and the position of the sweeping blades, control the sweeping blades to rotate to their limit positions or not to rotate; where z is the stationary angle of the sweeping blades; the limit positions include the leftmost angle A.
