Based on the hardware structure, the embodiment of the vortex ring focusing method of the air conditioner is provided.
Referring to fig. 2, fig. 2 is a flow chart illustrating a method for focusing a vortex ring of an air conditioner according to a first embodiment of the present invention.
In a first embodiment, the air conditioner vortex ring focusing method includes the steps of:
and step S10, acquiring a body surface temperature distribution map of the user.
It should be noted that, the execution subject of the embodiment is a controller in an air conditioner, for example, a central controller in an air conditioner, and may also be a controller in another form. The body surface temperature distribution map of the user can be acquired by combining an infrared sensor with an image recognition technology.
It should be noted that, the execution main body of the embodiment is a controller in an air conditioner, for example, a central controller in an air conditioner, and may also be a controller in other forms, which is not limited in this embodiment, the central controller is taken as an example to illustrate, a vortex ring generator is arranged on the air conditioner, such as the schematic diagram of focusing a vortex ring on a body part of a user, shown in fig. 4 to 7, a front view, an air outlet aperture schematic diagram, and a top view of the air conditioner, the vortex ring generator 10 in fig. 4 performs air treatment through a vortex ring channel 20, generates a vortex ring 30 with a certain diameter from the air outlet aperture, and realizes air supply to the user 40, where the vortex ring is a circular ring whose inside is filled with air, a vortex ring air outlet 401 is arranged directly above the air conditioner in fig. 5, such as the front view of the air outlet aperture shown in fig. 6, and the air outlet aperture is a square with a preset size, the present embodiment does not limit this to other shapes, and as shown in the top view of the air outlet aperture shown in fig. 7, a wind deflector 601 is further disposed near the vortex ring air outlet 602, so as to change the angle of the wind direction and achieve the purpose of controlling the direction of the vortex ring.
It should be noted that fig. 3 is a schematic diagram of the body temperature of the air conditioner according to an embodiment of the present invention; fig. 3 is for reference only, and the body surface temperature profile may take other forms in an implementation. In this embodiment, to facilitate explanation, a body temperature map when the user is in a standing posture is used, and the user may take other postures according to the body surface temperature distribution map obtained in the specific implementation.
And step S20, obtaining the body surface temperature of the user according to the body surface temperature distribution map, determining a to-be-selected part of which the body surface temperature exceeds a preset temperature range, and taking the to-be-selected part as a target part.
It should be noted that the temperature of each part on the body of the user can be obtained through the body surface temperature distribution map, and the preset temperature range is the temperature comfortable for the user to feel. And in the air-conditioning refrigeration mode, when the body surface temperature is greater than the highest value of the temperature range, the part corresponding to the body surface temperature is the part to be selected. And in the air-conditioning heating mode, when the body surface temperature is lower than the lowest value of the temperature range, the part corresponding to the body surface temperature is the part to be selected. The user may have a plurality of parts to be selected, and the target part which can bear vortex ring focusing and has body surface temperature exceeding the range is selected according to the image identification.
In specific implementations, for example: if the current mode is a refrigeration mode, selecting a part on the body of the user, which is higher than a preset temperature range; the temperature of the head, hands and chest of the user is high and exceeds the preset temperature range. Wherein, the head temperature of the user is the highest, the chest is a little inferior, the palm temperature of the hand is higher, the back temperature of the hand is low, the area of the hand is smaller, and the effect of the hand on cooling the body is not effective on the head and the chest. The chest of the user has little difference in temperature from the head and is more adaptable to wind than the chest, so the chest is taken as a target part.
In specific implementation, the target part can be obtained according to the actual condition of the body of the user; and a target part on the body of the user can be selected according to the instruction content by receiving an air supply instruction of the user. When the user changes the posture when the vortex ring is focused on the body part, the target part focus is obtained again, so that the vortex ring can be continuously focused on the body of the user along with the change of the posture of the user, and better experience is brought to the user.
And step S30, determining the current distance information between the target part and the air conditioner.
It should be noted that the distance between the target part on the body of the user and the air conditioner can be obtained in real time by means of an infrared sensor or an ultrasonic sensor, an image recognition technology, and the like. Specifically, the central position of the target part is determined according to the body surface temperature distribution map; and acquiring the current distance information between the central position and an air outlet of the air conditioner. The current distance information is a straight-line distance between the center position and the air outlet.
And step S40, adjusting the setting parameters of the vortex ring generator according to the current distance information.
It is easy to understand that the vortex ring can change due to air resistance in the process of movement, and the setting parameters need to be adjusted according to the current distance information so as to send the vortex ring meeting the wind feeling experience of a user. The setting parameters include a target pulse duration and target air amount information. Analyzing the area of the target part to obtain the size of the generated vortex ring, wherein the vortex ring with smaller diameter has stronger wind feeling and better focusing effect; the parameters of the vortex ring generator with smaller outlet caliber, longer pulse time and smaller air quantity are preferably set, so that the vortex ring generator generates a vortex ring with smaller diameter, and the precision of local air supply is higher; for example: the outlet aperture of the film type vortex ring generator is 90mm, the pulse time is 0.073s, and the air quantity is 5.28L, so that the vortex ring generator generates a vortex ring with the diameter of 20 cm.
It should be noted that the air outlet aperture is a characteristic parameter of the air outlet of the vortex ring generator, and if the shape of the air outlet is circular, the diameter of the circle is the air outlet aperture; when the air outlet is square, the side length is the air outlet caliber. And the target pulse duration and the target air amount information are parameters that can be set by the central controller.
And step S50, driving the vortex ring generator according to the setting parameters, so that the vortex ring generator generates a vortex ring facing the target portion.
In a specific implementation, referring to FIG. 4, FIG. 4 is a schematic illustration of the focus of the vortex ring on a user's body part. The vortex ring generator is driven through the target pulse duration and the target air amount information, so that the vortex ring generator generates a vortex ring facing to a target part, a user feels a wind through the vortex ring, and the comfort of the user is improved.
According to the embodiment, through the scheme, the distance information between the target part and the air supply outlet of the vortex ring generator is acquired by acquiring the body surface temperature of the user and selecting the target part, so that the vortex ring focused on the local body of the user is generated, and the user can obtain better wind feeling experience.
Further, as shown in fig. 3, a second embodiment of the air conditioner vortex ring focusing method according to the present invention is proposed based on the first embodiment of the air conditioner vortex ring focusing method according to the present invention, and in this embodiment, after step S30, the method further includes:
step S301, acquiring a space angle between the central position of the target part and an air outlet of the air conditioner.
It is easily understood that the spatial angle includes an angle including a vertical direction and a horizontal direction. Based on the sensor and the image recognition technology in the first embodiment of the air conditioner vortex ring focusing method, the corresponding space angle can be obtained.
Step S302, adjusting the horizontal direction and the vertical direction of the air outlet of the vortex ring generator according to the space angle.
In specific implementation, the left-right rotation angle of the air outlet of the vortex ring generator is adjusted according to the horizontal angle, for example: a horizontal turntable can be arranged on the generator, and the turntable is driven by a motor to rotate in the horizontal direction; adjusting the vertical rotation angle of the air outlet of the vortex ring generator according to the vertical angle, for example: the middle parts of two sides of the generator are respectively provided with a motor, the motor drives the vortex ring generator to rotate in the vertical direction, the motor is arranged on a motor bracket, and the lower end of the motor bracket is fixed on the horizontal turntable; the center of the air outlet is consistent with the center of the target part. Through the arrangement, the air outlet is aligned to the target position, and directional air supply is realized. The air outlet of the vortex ring generator can also be driven to rotate by the magnetic suspension device.
Step S40 specifically includes:
step S401, a target vortex ring diameter is obtained according to the target position and the current distance information, and the target vortex ring diameter is the diameter of the vortex ring when the vortex ring is generated.
It should be noted that, based on the first embodiment of the method for focusing a vortex ring of an air conditioner of the present invention, the diameter of the air outlet of the vortex ring generator is a characteristic parameter, the diameter of the vortex ring when the vortex ring reaches the target portion on the body of the user can be known according to the area of the target portion on the body of the user and the current distance information, and the diameter of the vortex ring when the vortex ring is generated needs to be controlled in order to control the diameter of the vortex ring focused on the local portion of the body of the user.
Step S402, determining the target pulse duration and the target air volume information of the vortex ring generator according to the target vortex ring diameter and the current distance information.
It should be noted that, a vortex ring target speed is obtained according to the target vortex ring diameter and the current distance information, where the vortex ring target speed is a moving speed of a vortex ring moving to a user; and acquiring the target pulse duration and the target air quantity information of the vortex ring generator according to the target speed of the vortex ring.
As shown in fig. 10, the state of the film vortex ring generator before compression is schematically illustrated, the film vortex ring generator includes an outer fixing plate 901, an inner fixing plate 902, a diaphragm 903, an air duct 904, and a rack 905, and the state of the film vortex ring generator when compression is finished is schematically illustrated in fig. 11.
It is easy to understand that when the vortex ring generator is of an air flow on-off type, such as a movable vane on-off type vortex ring generator, the vane is opened from an initial position to a set position, then optionally stopped, and then the vane starts to be closed to be completely closed and returns to the initial position, and the time which the vane passes from the start to the complete closing is defined as the pulse time of the generator; wherein, the position of the blade before starting each opening and closing period is defined as the initial position. As shown in fig. 8, which is a state where the movable vane is fully opened, the flowing air can pass; as shown in fig. 9, which is a state in which the movable vane is fully closed, the flowing air cannot pass through,
in the process of completing the one-off structure when the vortex ring is generated, the amount of air passing through the vortex ring generator,
v is the air outlet speed, S is the air outlet area, in the one-time on-off process, the air outlet is completely closed, completely opened and then completely closed, the area change of the air outlet is 0-max-0, and the average value can be taken; t is the on-off time, namely the time that the air outlet is completely closed, completely opened and then completely closed in the one-time on-off process.
When the vortex ring generator is an on-off vortex ring generator, the step of driving the vortex ring generator according to the setting parameters to enable the vortex ring generator to generate a vortex ring facing the target part specifically comprises the following steps: controlling the movement time of a wind shield of the vortex ring generator from an open state to a closed state according to the target pulse duration; controlling the channel cross-sectional area of a channel where a wind shield of the vortex ring generator is located according to the target air quantity information; and driving the vortex ring generator according to the movement time of the wind shield from the opening state to the closing state and the cross section area of the channel, so that the vortex ring generator generates vortex rings towards the target part.
It will be readily appreciated that when the vortex ring generator is of the compression type, for example a film vortex ring generator, the film starts compressing air from an initial position, moves to a set position and then optionally pauses, after which the film begins to deform and returns to the initial position, and that the pause is also selected to define the time it takes for the film to start compressing air from the initial position and move to the set position as the pulse time of the generator; wherein, the position where the film starts to be compressed is defined as an initial position; defining the position of the film after each compression as a positioning position; wherein both the initial position and the positioning position can be reset.
It should be noted that, for the compression type, such as the film type vortex ring generator, the film starts to compress air from the initial position, moves to the positioning position, then optionally stops, and then begins to deform, returns to the initial position, and also optionally stops, and the definition V is the air volume of the film starting to compress air from the initial position, and the vortex ring generator moves to the positioning position to compress the air in the cavity, and the V is the air volume at the maximum compression stroke.
The vortex ring generator is a compression type vortex ring generator, and the setting parameters comprise target pulse duration and target air amount information; the step of driving the vortex ring generator according to the setting parameters to enable the vortex ring generator to generate a vortex ring facing the target portion specifically includes: controlling the movement time of a membrane part in the vortex ring generator from an initial position to a positioning position according to the target pulse duration; controlling the compression amount of the membrane part according to the target air amount information; and driving the vortex ring generator according to the movement time and the compression amount of the film moving from the initial position to the positioning position, so that the vortex ring generator generates vortex rings facing the target part.
According to the method, the direction of the air outlet of the vortex ring generator is adjusted, and the target pulse duration and the target air volume information of the vortex ring generator are controlled, so that the vortex ring can be focused on the local part of the body of a user, and the wind sensation experience of the user is improved.
The invention further provides a vortex ring focusing device of the air conditioner.
Referring to fig. 4, fig. 4 is a functional block diagram of a vortex ring focusing apparatus of an air conditioner according to a first embodiment of the present invention. The air conditioner vortex ring focusing apparatus includes:
and the distribution diagram acquisition module 10 is used for acquiring a body surface temperature distribution diagram of the user.
It should be noted that, the execution subject of the embodiment is a controller in an air conditioner, for example, a central controller in an air conditioner, and may also be a controller in another form. The body surface temperature distribution map of the user can be acquired by combining an infrared sensor with an image recognition technology.
And the target determining module 20 is configured to obtain the body surface temperature of the user according to the body surface temperature distribution map, determine a to-be-selected portion of which the body surface temperature exceeds a preset temperature range, and use the to-be-selected portion as a target portion.
It should be noted that the temperature of each part on the body of the user can be obtained through the body surface temperature distribution map, and the preset temperature range is the temperature comfortable for the user to feel. And in the air-conditioning refrigeration mode, when the body surface temperature is greater than the highest value of the temperature range, the part corresponding to the body surface temperature is the part to be selected. And in the air-conditioning heating mode, when the body surface temperature is lower than the lowest value of the temperature range, the part corresponding to the body surface temperature is the part to be selected. The user may have a plurality of parts to be selected, and the target part which can bear vortex ring focusing and has body surface temperature exceeding the range is selected according to the image identification.
In specific implementations, for example: if the current mode is a refrigeration mode, selecting a part on the body of the user, which is higher than a preset temperature range; the temperature of the head, hands and chest of the user is high and exceeds the preset temperature range. Wherein, the head temperature of the user is the highest, the chest is a little inferior, the palm temperature of the hand is higher, the back temperature of the hand is low, the area of the hand is smaller, and the effect of the hand on cooling the body is not effective on the head and the chest. The chest of the user has little difference in temperature from the head and is more adaptable to wind than the chest, so the chest is taken as a target part.
In specific implementation, the target part can be obtained according to the actual condition of the body of the user; and a target part on the body of the user can be selected according to the instruction content by receiving an air supply instruction of the user. When the user changes the posture when the vortex ring is focused on the body part, the target part focus is obtained again, so that the vortex ring can be continuously focused on the body of the user along with the change of the posture of the user, and better experience is brought to the user.
And the distance determining module 30 is used for determining the current distance information between the target part and the air conditioner.
It should be noted that the distance between the target part on the body of the user and the air conditioner can be obtained in real time by means of an infrared sensor or an ultrasonic sensor, an image recognition technology, and the like. Specifically, the central position of the target part is determined according to the body surface temperature distribution map; and acquiring the current distance information between the central position and an air outlet of the air conditioner. The current distance information is a straight-line distance between the center position and the air outlet.

Based on the sensor and the image recognition technology in the first embodiment of the air conditioner vortex ring focusing method, the corresponding space angle can be obtained.
And adjusting the horizontal direction and the vertical direction of the air outlet of the vortex ring generator according to the space angle.
In specific implementation, the left-right rotation angle of the air outlet of the vortex ring generator is adjusted according to the horizontal angle, for example: a horizontal turntable can be arranged on the generator, and the turntable is driven by a motor to rotate in the horizontal direction; adjusting the vertical rotation angle of the air outlet of the vortex ring generator according to the vertical angle, for example: the middle parts of two sides of the generator are respectively provided with a motor, the motor drives the vortex ring generator to rotate in the vertical direction, the motor is arranged on a motor bracket, and the lower end of the motor bracket is fixed on the horizontal turntable; the center of the air outlet is consistent with the center of the target part. Through the arrangement, the air outlet is aligned to the target position, and directional air supply is realized. The air outlet of the vortex ring generator can also be driven to rotate by the magnetic suspension device.

It should be noted that the air outlet aperture is a characteristic parameter of the air outlet of the vortex ring generator, and if the shape of the air outlet is circular, the diameter of the circle is the air outlet aperture; when the air outlet is square, the side length is the air outlet caliber. And the target pulse duration and the target air amount information are parameters that can be set by the central controller.
And acquiring the diameter of a target vortex ring according to the target part and the current distance information, wherein the diameter of the target vortex ring is the diameter of the vortex ring when the vortex ring is generated.
It should be noted that, based on the first embodiment of the method for focusing a vortex ring of an air conditioner of the present invention, the diameter of the air outlet of the vortex ring generator is a characteristic parameter, the diameter of the vortex ring when the vortex ring reaches the target portion on the body of the user can be known according to the area of the target portion on the body of the user and the current distance information, and the diameter of the vortex ring when the vortex ring is generated needs to be controlled in order to control the diameter of the vortex ring focused on the local portion of the body of the user.

In the process of completing the one-off structure when the vortex ring is generated, the amount of air passing through the vortex ring generator,
v is the air outlet speed, S is the air outlet area, in the one-time on-off process, the air outlet is completely closed, completely opened and then completely closed, the area change of the air outlet is 0-max-0, and the average value can be taken; t is the on-off time, namely the time that the air outlet is completely closed, completely opened and then completely closed in the one-time on-off process.

It will be readily appreciated that when the vortex ring generator is of the compression type, for example a film vortex ring generator, the film starts compressing air from an initial position, moves to a set position and then optionally pauses, after which the film begins to deform and returns to the initial position, and that the pause is also selected to define the time it takes for the film to start compressing air from the initial position and move to the set position as the pulse time of the generator; wherein, the position where the film starts to be compressed is defined as an initial position; defining the position of the film after each compression as a positioning position; wherein both the initial position and the positioning position can be reset.
It should be noted that, for the compression type, such as the film type vortex ring generator, the film starts to compress air from the initial position, moves to the positioning position, then optionally stops, and then begins to deform, returns to the initial position, and also optionally stops, and the definition V is the air volume of the film starting to compress air from the initial position, and the vortex ring generator moves to the positioning position to compress the air in the cavity, and the V is the air volume at the maximum compression stroke.
The vortex ring generator is a compression type vortex ring generator, and the setting parameters comprise target pulse duration and target air amount information; the step of driving the vortex ring generator according to the setting parameters to enable the vortex ring generator to generate a vortex ring facing the target portion specifically includes: controlling the movement time of a membrane part in the vortex ring generator from an initial position to a positioning position according to the target pulse duration; controlling the compression amount of the membrane part according to the target air amount information; and driving the vortex ring generator according to the movement time and the compression amount of the film moving from the initial position to the positioning position, so that the vortex ring generator generates vortex rings facing the target part.
