In addition, the operation of the step of determining the target pulse duration threshold range capable of generating the vortex ring with the wake based on the parameter information is to acquire a target speed of the vortex ring with the wake and distance information between the air conditioner and a user, the target speed of the vortex ring is a moving speed of the vortex ring with the wake moving to the user, a first corresponding relation between an initial speed of the vortex ring with the wake and the air volume information is established based on the target speed of the vortex ring, the distance information and the air outlet aperture, a second corresponding relation between the initial speed of the vortex ring and the pulse duration is acquired, and the target pulse duration threshold range with the wake corresponding to the vortex ring generator is determined according to the first corresponding relation and the second corresponding relation.
And step S30, selecting the current pulse duration from the target pulse duration threshold range.
And establishing a mapping relation table according to the target pulse duration threshold range, the parameter information of the vortex ring generator and the distance information between the air conditioner and the user.
The current pulse duration is the pulse duration corresponding to the vortex ring with the trail generated according to the current blowing instruction, wherein the current pulse duration can be the pulse duration corresponding to the vortex ring with the trail generated according to the current blowing instruction selected by a user, the distance information between the air conditioner and the user and the current parameter information of the vortex ring generator are obtained, then the current pulse duration corresponding to the vortex ring with the trail can be determined according to the distance information and the current parameter information, the current pulse duration is searched in a mapping relation table according to the current pulse duration and whether the current pulse duration is in a target pulse duration threshold range or not is judged, and if the current pulse duration is in the target pulse duration threshold range, the vortex ring generator is determined to generate the vortex ring with the trail according to the current pulse duration.
The current parameter information and the distance information in the mapping relation table are searched according to the distance information and the current parameter information, the current parameter information and the distance information in the mapping relation table are traversed, the traversed parameter information to be confirmed and the traversed distance information serve as parameter information to be matched, the parameter information to be matched is matched in the mapping relation table, if the parameter information to be matched is matched in the mapping relation table in a consistent mode, the pulse duration corresponding to the parameter information to be matched is obtained from the mapping relation table, the pulse duration corresponding to the parameter information to be matched is selected from the target pulse duration threshold range, and the pulse duration corresponding to the parameter information to be matched serves as the current pulse duration corresponding to the current parameter information; and if the parameter information to be matched is not matched and consistent in the mapping relation table, returning to the step of traversing the current parameter information in the mapping relation table. Wherein the target pulse duration threshold range is a target pulse duration threshold range obtained by the inventor in carrying out the vortex ring capable of generating the wake.
Further, for ease of understanding, the following is exemplified:
when the vortex ring generator generates a vortex ring, relevant parameters such as air outlet aperture, air quantity and pulse duration are provided, if the air outlet aperture is 190mm, the distance information is 3m, the air quantity is within 1.4s of a certain pair of vortex wheels, when the double-opening rotating speed is 500, the air quantity passes through the vortex ring, when the pulse duration is 0.02s, the vortex ring has no trail in the air, and the air supply is rapid; the pulse time of the generator is prolonged from 0.02s to 0.22s, at the moment, the vortex ring has an obvious trail in the air, the wind continuity is increased, the user experiences a more comfortable wind feeling, when the pulse time is increased to 0.34s, the trail of the vortex ring in the air is longer, the vortex ring blows the wind on the user, the coverage area is large, the vortex ring is more comfortable, and therefore the pulse duration threshold is set to be 0.34 s. Therefore, a target pulse duration not less than the pulse duration threshold, such as 0.35s, may be set, and finally a vortex ring with a wake is generated by the vortex ring generator based on the target pulse duration being 0.35 s. If the time is increased to 1.2s, it is found that the time is too long just to allow the vortex ring with the wake to blow off the user, it can be seen that the target pulse duration threshold range can be set to 0.22s-1.2 s.
Determining the relationship between the parameter information of the vortex ring generator and the pulse duration threshold, wherein the method can be that the relationship between the parameter information and the pulse duration threshold is determined according to the distance between a user and an air conditioner, for example, the pulse duration of the generator is prolonged from 0.02s to 0.22s, a comfortable wind sensation exists at 4 meters, the pulse duration of the generator is continuously prolonged to 0.34s corresponding to the rotating speed of a fan of 500 revolutions, the air supply distance is reduced, and the wind sensation at 4 meters is weakened; similarly, when the opening and closing time is 0.34s, comfortable wind feeling exists at the position of 3 meters, and the corresponding rotating speed is 400 revolutions; therefore, the relation between the parameter information related to the vortex ring generator and the target pulse duration threshold range can be confirmed based on the distance between the user and the air conditioner.
The parameter information may also determine a maximum pulse time during which a vortex ring can be generated, the target pulse time being less than the maximum pulse time;
when the pulse duration is 0.02s, the vortex ring has no wake in the air, and the air supply is rapid; the pulse time of the generator is prolonged from 0.02s to 0.22s, at the moment, the vortex ring has obvious wake in the air, the user experience is comfortable, and when the pulse time is 0.34s, the wake of the vortex ring in the air is longer, the wind blown to the user is scattered, the coverage area is large, and the generator is more comfortable; when the pulse duration is 0.54s, the vortex ring has a short movement distance and cannot blow to a user with a relatively long distance; the parametric information may also determine a maximum pulse time 0.54s at which a vortex ring can be generated, the target pulse time being less than the maximum pulse time 0.54s, and the target pulse duration being greater than the 0.22 s.
Step S40, the vortex ring generator is driven according to the current pulse duration, so that the vortex ring generator generates a vortex ring with a trail.
In a specific implementation, the movement time of a film part in the compression-type vortex ring generator from an initial position to a positioning position is controlled according to the current pulse duration, and the compression-type vortex ring generator is driven according to the movement time of the film part from the initial position to the positioning position and parameter information corresponding to the compression-type vortex ring generator, so that the compression-type vortex ring generator generates a vortex ring with a trail.
In addition, the operation of the step of determining the target pulse duration threshold range capable of generating the vortex ring with the wake based on the parameter information is to acquire a target speed of the vortex ring with the wake and distance information between the air conditioner and a user, the target speed of the vortex ring is a moving speed of the vortex ring with the wake moving to the user, a first corresponding relation between an initial speed of the vortex ring with the wake and the air volume information is established based on the target speed of the vortex ring, the distance information and the air outlet aperture, a second corresponding relation between the initial speed of the vortex ring and the pulse duration is acquired, and the target pulse duration threshold range with the wake corresponding to the vortex ring generator is determined according to the first corresponding relation and the second corresponding relation.
In a specific implementation, the vortex ring generator is driven by the current distance information and the current parameters of the vortex ring generator, so that the vortex ring generator generates a vortex ring with a trail facing the user direction, and thus, the user can contact and blow air for a long time and in a large area, and feel soft, so as to improve the comfort of the user.
According to the scheme, the vortex ring generator is arranged on the air conditioner by acquiring the current distance information between the air conditioner and a user; and acquiring current parameter information of a vortex ring generator, determining current pulse duration according to the current distance information and the current parameter information, judging whether the current pulse duration is in a target pulse duration threshold range, and if the current pulse duration is in the target pulse duration threshold range, driving the vortex ring generator according to the current pulse duration to enable the vortex ring generator to generate a vortex ring with a trail facing to a user direction, so that the user can feel soft, and the generated wind can be blown to the user in a large area and for a long time, thereby improving the user experience effect.
Further, as shown in fig. 9, a second embodiment of the method for generating a vortex ring with a wake according to the present invention is proposed based on the first embodiment, in this embodiment, the step S20 includes:
step S201, the parameter information includes air outlet aperture and air amount information, and obtains a vortex ring target speed with a trail and distance information between the air conditioner and a user, where the vortex ring target speed is a moving speed of the vortex ring with the trail moving to the user.
It should be noted that the target speed of the vortex ring is set to 1m/s, that is, the wind speed when the vortex ring reaches the user, because 1m/s is the optimal speed, that is, the wind speed felt by people is the most comfortable, and may also be other parameter information, this embodiment does not limit this, in this embodiment, 1m/s is taken as an example to explain, the current outlet aperture is 150mm, the size of the pre-designed outlet aperture is taken as the size, and may also be other size information, and flexible adjustment may be performed according to requirements, this embodiment does not limit this, in this embodiment, only the outlet aperture of 150mm is taken as an example to explain, and the air amount is set to 5.28L, and continue to express the initial speed of the vortex ring as shown in V0 in fig. 4, V denotes the target speed of the vortex ring, and D denotes the current outlet aperture.
Step S202, establishing a first corresponding relation between the vortex ring initial speed with the trail and the air quantity information based on the vortex ring target speed, the distance information and the air outlet aperture.
It can be understood that the first corresponding relationship is a formula (1) of V0 ═ V + L × F (T, D, Q), where V0 represents the vortex ring initial speed, V represents the vortex ring target speed, T represents the pulse duration, D represents the current air outlet aperture, Q represents the air volume information, and F represents a functional relationship.
In a specific implementation, a relational expression between the vortex ring target speed and the distance information is first obtained, where V is F (V0, L, K) formula (2), where V is the vortex ring target speed, V0 is the vortex ring initial speed, L is the distance information, and K is a coefficient, as shown in fig. 10, a relational graph between the vortex ring target speed, that is, the vortex ring speed and the distance information, is then obtained according to formulas (2) and (3), as K is related to the vortex ring generator pulse time T, the air outlet aperture D, and the air amount Q, defined as K is F (T, D, Q) formula (3).

A selecting module 1103, configured to select a current pulse duration from the target pulse duration threshold range;
and establishing a mapping relation table according to the target pulse duration threshold range, the parameter information of the vortex ring generator and the distance information between the air conditioner and the user.
The current pulse duration is the pulse duration corresponding to the vortex ring with the trail generated according to the current blowing instruction, wherein the current pulse duration can be the pulse duration corresponding to the vortex ring with the trail generated according to the current blowing instruction selected by a user, the distance information between the air conditioner and the user and the current parameter information of the vortex ring generator are obtained, then the current pulse duration corresponding to the vortex ring with the trail can be determined according to the distance information and the current parameter information, the current pulse duration is searched in a mapping relation table according to the current pulse duration and whether the current pulse duration is in a target pulse duration threshold range or not is judged, and if the current pulse duration is in the target pulse duration threshold, the vortex ring generator is determined to generate the vortex ring with the trail according to the current pulse duration.
The current parameter information and the distance information in the mapping relation table are searched according to the distance information and the current parameter information, the current parameter information and the distance information in the mapping relation table are traversed, the traversed parameter information to be confirmed and the traversed distance information serve as parameter information to be matched, the parameter information to be matched is matched in the mapping relation table, if the parameter information to be matched is matched in the mapping relation table in a consistent mode, the pulse duration corresponding to the parameter information to be matched is obtained from the mapping relation table, the pulse duration corresponding to the parameter information to be matched is selected from the target pulse duration threshold range, and the pulse duration corresponding to the parameter information to be matched serves as the current pulse duration corresponding to the current parameter information; and if the parameter information to be matched is not matched and consistent in the mapping relation table, returning to the step of traversing the current parameter information in the mapping relation table. Wherein the target pulse duration threshold range is a target pulse duration threshold range obtained by the inventor in carrying out the vortex ring capable of generating the wake.
Further, for ease of understanding, the following is exemplified:
when the vortex ring generator generates a vortex ring, relevant parameters such as air outlet aperture, air quantity and pulse duration are provided, if the air outlet aperture is 190mm, the distance information is 3m, the air quantity is within 1.4s of a certain pair of vortex wheels, when the double-opening rotating speed is 500, the air quantity passes through the vortex ring, when the pulse duration is 0.02s, the vortex ring has no trail in the air, and the air supply is rapid; the pulse time of the generator is prolonged from 0.02s to 0.22s, at the moment, the vortex ring has an obvious trail in the air, the wind continuity is increased, the user experiences a more comfortable wind feeling, when the pulse time is increased to 0.34s, the trail of the vortex ring in the air is longer, the vortex ring blows the wind on the user, the coverage area is large, the vortex ring is more comfortable, and therefore the pulse duration threshold is set to be 0.34 s. Therefore, a target pulse duration not less than the pulse duration threshold, such as 0.35s, may be set, and finally a vortex ring with a wake is generated by the vortex ring generator based on the target pulse duration being 0.35 s. If the time is increased to 1.2s, it is found that the time is too long just to allow the vortex ring with the wake to blow off the user, it can be seen that the target pulse duration threshold range can be set to 0.22s-1.2 s.
Determining the relationship between the parameter information of the vortex ring generator and the pulse duration threshold, wherein the method can be that the relationship between the parameter information and the pulse duration threshold is determined according to the distance between a user and an air conditioner, for example, the pulse duration of the generator is prolonged from 0.02s to 0.22s, a comfortable wind sensation exists at 4 meters, the pulse duration of the generator is continuously prolonged to 0.34s corresponding to the rotating speed of a fan of 500 revolutions, the air supply distance is reduced, and the wind sensation at 4 meters is weakened; similarly, when the opening and closing time is 0.34s, comfortable wind feeling exists at the position of 3 meters, and the corresponding rotating speed is 400 revolutions; therefore, the relation between the parameter information related to the vortex ring generator and the target pulse duration threshold range can be confirmed based on the distance between the user and the air conditioner.
The parameter information may also determine a maximum pulse time during which a vortex ring can be generated, the target pulse time being less than the maximum pulse time;
when the pulse duration is 0.02s, the vortex ring has no wake in the air, and the air supply is rapid; the pulse time of the generator is prolonged from 0.02s to 0.22s, at the moment, the vortex ring has obvious wake in the air, the user experience is comfortable, and when the pulse time is 0.34s, the wake of the vortex ring in the air is longer, the wind blown to the user is scattered, the coverage area is large, and the generator is more comfortable; when the pulse duration is 0.54s, the vortex ring has a short movement distance and cannot blow to a user with a relatively long distance; the parametric information may also determine a maximum pulse time 0.54s at which a vortex ring can be generated, the target pulse time being less than the maximum pulse time 0.54s, and the target pulse duration being greater than the 0.22 s.

In addition, the operation of the step of determining the target pulse duration threshold range capable of generating the vortex ring with the wake based on the parameter information is to acquire a target speed of the vortex ring with the wake and distance information between the air conditioner and a user, the target speed of the vortex ring is a moving speed of the vortex ring with the wake moving to the user, a first corresponding relation between an initial speed of the vortex ring with the wake and the air volume information is established based on the target speed of the vortex ring, the distance information and the air outlet aperture, a second corresponding relation between the initial speed of the vortex ring and the pulse duration is acquired, and the target pulse duration threshold range with the wake corresponding to the vortex ring generator is determined according to the first corresponding relation and the second corresponding relation.
