Detailed Description
The present invention will be described in further detail with reference to the following detailed description and accompanying drawings.
The embodiment of the invention provides a bladeless fan capable of intelligently adjusting a rotation angle, as shown in fig. 1, the bladeless fan comprises a base 1 and a bladeless fan body rotatably arranged on the base 1, the bladeless fan body comprises a base 2 and an air ring 3 fixed on the base 2, a fan assembly and an air channel are arranged in the base 2, an air outlet communicated with the air channel is formed in the air ring 3, the fan assembly blows air to the air outlet through the air channel, so that air flow is generated, and the function of the bladeless fan is realized.
In the embodiment, the camera 31 is fixed on the wind ring 3, as shown in the figure, the camera 31 can be located at the top of the wind ring 3, and the camera 31 is located on a central vertical line of the wind ring 3, because the bladeless fan is usually horizontally placed, the central vertical line is a vertical line which passes through an axial lead of the wind ring 3 and is perpendicular to the horizontal direction, a lens axial direction of the camera 31 is parallel to an axial direction of the wind ring 3, and the camera 31 shoots towards an air blowing direction, the arrangement of the structure is aimed at ensuring that an air blowing range of the wind ring 3 is basically consistent with an air blowing range shot by the camera 31, so that the facing position of the camera 31 is kept synchronous with an air blowing position of the wind ring 3.
The base 1 is internally provided with a motor 11, a rotating shaft 12 of the motor 11 is fixedly connected with the bottom of the base 2, and the rotating shaft 12 drives the bladeless fan body to rotate correspondingly when rotating. The base 1 is partially disassembled for easy viewing, and in fact, the motor 11 is disposed in the base 1, and the base 1 and the base 2 are rotatably connected.
An angle sensor 13 for detecting the deflection angle of the bladeless fan body relative to the base 1 is arranged at the bottom of the bladeless fan body or on the rotating shaft 12, as shown in the figure, the angle sensor 13 is fixed on the rotating shaft 12, the rotating shaft 12 rotates to drive the bladeless fan body to rotate, and when the bladeless fan body rotates to a position, the bladeless fan body generates a deflection angle relative to the base 1. In order to unify the measurement of the angle values, an angle start line may be set, and the angle produced with respect to the angle start line may be calculated as the deflection angle. As shown in fig. 2, the line OM is an angle starting line, and the point O is the axial position of the rotating shaft 12. The angle sensor 13 may be an electronic compass, an angle gauge, or the like.
The camera 31, the angle sensor 13 and the motor 12 are all connected with the controller, images collected by the camera 31 and data collected by the angle sensor 13 can be transmitted to the controller, the controller can send out instructions to control the motor 12 to rotate forwards or backwards, the rotating speed of the motor 12 can be controlled through the change of voltage or current, and then the rotating speed of the bladeless fan body is adjusted. Generally, the bladeless fan body swings back and forth within a certain angle range, so that when the bladeless fan body rotates from the starting position to the end position, and rotates from the end position back to the starting position, a rotation period is considered.
The controller of the present embodiment is configured to execute the following program:
the bladeless fan body is provided with an initial first preset angle range, and after the bladeless fan is started each time, the controller drives the bladeless fan body to rotate within the initial first preset angle range; in the rotating process of the bladeless fan body, the camera 31 shoots in real time, the controller can conduct face recognition on a picture shot by the camera 31, and when the face is recognized, it is indicated that a user is using the bladeless fan.
The picture shot by the camera 31 is two-dimensional and has a length direction and a height direction, the middle position of the shot picture refers to the middle area of the length direction, and since the camera 31 is located on the central vertical line of the wind ring 3, when a human face exists at the middle position of the shot picture, it indicates that the wind ring 3 is blowing towards the user.
As shown in FIG. 2, when the face at the position of the A point is in the middle position of the shot picture, ∠ MOA is calculated and recorded immediately, the angle is the first recorded deflection angle.
As shown in fig. 2, if there are a plurality of records of deflection angles within a first preset angle range, if both points a and D have human faces, then there are ∠ MOA and ∠ MOD records of deflection angles, respectively, then the maximum deflection angle and the minimum deflection angle among the recorded deflection angles within the first preset angle range are determined, in fig. 2, ∠ MOA and ∠ MOD are respectively the minimum deflection angle and the maximum deflection angle within the first preset angle range, then the bladeless fan will adjust its rotation range, and further drive the bladeless fan body to rotate only between the maximum deflection angle and the minimum deflection angle, i.e. only within the range of angle AOD, so that the user at points a and D can blow air quickly, in fig. 2, the angle value of the first preset angle range is α 1, of course, in order to reduce the sense of discomfort of blowing air all the way to the user, a delay angle may be added to the determined original maximum deflection angle, subtracted from the determined maximum deflection angle, and the determined minimum deflection angle is subtracted from the determined final deflection angle, thereby determining the final deflection angle of the original deflection angle, thereby determining the back-and forth, the final deflection angle.
Generally, due to the limitations of the fan's rotating structure, the bladeless fan body has a maximum rotation range, i.e. a maximum preset angle range within which all recorded deflection angles and the determined rotation angle range should be located, as shown in fig. 2 and 3, ∠ MON can be set to be the maximum preset angle range, which is α 3.
In one embodiment, if there may be only one face within the first predetermined angle range, or even if there may be no face, the corresponding deflection angle is recorded as one or no, in which case, it may be that the range value of the first predetermined angle range is too small, and there is an unrecognized user.
In the rotation process within the second preset angle range, the camera 31 still shoots in real time, the controller identifies the face in the shot picture in real time, once the face is identified to exist at the middle position of the picture shot by the camera 31, the angle value is immediately obtained from the angle sensor 13, and the deflection angle of the bladeless fan body when the face exists at the middle position of the shot picture is recorded. If a plurality of deflection angles exist in the second preset angle range, determining the maximum deflection angle and the minimum deflection angle in the deflection angles recorded in the second preset angle range, and further driving the bladeless fan body to rotate only between the maximum deflection angle and the minimum deflection angle.
As shown in fig. 2, if only one face at point a exists in the first preset angle range, only one angular deflection record ∠ MOA exists, at this time, the rotation range is expanded to the second preset angle range, two faces at point a and point B exist in the second preset angle range, and the records corresponding to two deflection angles ∠ MOA and ∠ MOB exist, ∠ MOA and ∠ MOB are respectively the minimum deflection angle and the maximum deflection angle in the second preset angle range, the bladeless fan will adjust the rotation range, and the controller will drive the bladeless fan body to rotate only between the maximum deflection angle and the minimum deflection angle.
Further, when there is only one record of deflection angle in the second preset angle range, it means that only one user is using the bladeless fan, and the bladeless fan body is driven to rotate within a third preset angle range taking the position corresponding to the user as an angular bisector, as shown in fig. 2, if there is only a record of deflection angle at point a, the bladeless fan body rotates within the range of ∠ COD with the segment OA as the angular bisector, so as to be used by the single user, but not allow the single user to wait too long before blowing wind.
In one embodiment, when there is no record of the deflection angle within the second predetermined angular range, it is stated that no user is using the bladeless fan. The timing is started from the record that the deflection angle does not exist in the second preset angle range, when the timing reaches the preset time, for example, ten minutes, and the deflection angle record does not exist in the preset time, which indicates that the bladeless fan is not used by the user in the preset time, the user probably does not use the bladeless fan any more, the controller can control the motor 11 and the bladeless fan body to stop working, the bladeless fan does not rotate and supplies air, and the bladeless fan automatically stops working when the bladeless fan is not used by people, so that the electric energy is saved.
In order to enrich the choices of the user and improve the user experience, the bladeless fan of the embodiment has a human-computer interaction function, for example, a control button is provided, so that the user can select the working mode of the bladeless fan. The user can select the multi-user mode, and the bladeless fan can realize the functions of the above embodiments. Of course, the user may also select the single mode in which the bladeless fan is turned on to follow the rotation by a single person.
Specifically, when only there is the record of a deflection angle in first preset angle scope, the controller will judge whether the operating mode of the bladeless fan of the intelligent regulation turned angle of this embodiment is single mode, if single mode, the controller will order about bladeless fan body to follow this people's face and rotate. Only the face of the person is always positioned in the middle of the picture shot by the camera 31 within the first preset angle range. When the user need continuously blow, even if user's position changes, the bladeless fan of this embodiment all can follow user's position change and rotate, need not user manual regulation bladeless fan's the position of blowing, and is more intelligent.
In one embodiment, when there are multiple recordings of deflection angles in the first preset angle range, it is indicated that there are multiple users using the bladeless fan, and the distance between two adjacent users is different because the users are located at different positions, and in the same angle range, the closer user has a higher density, and conversely, the closer user has a lower density. The controller may find out the dense face having the angle difference between the deflection angles corresponding to the adjacent faces smaller than the preset angle difference according to the deflection angle records, that is, when the angle difference between the deflection angle corresponding to a certain face and the deflection angle corresponding to at least one adjacent face is smaller than the preset angle (for example, the preset angle may be set to 15 °), the face is considered to be the dense face.
As shown in fig. 3, ∠ AOB, ∠ COB and ∠ EOF are all smaller than the preset angle, the faces at points A, B, C, E and F are dense faces, and point D is a non-dense face.
As shown in fig. 3, when A, B and C are not interrupted by non-dense faces, the region corresponding to ∠ AOC is the first dense region S1, when E and F are not interrupted by non-dense faces, the region corresponding to ∠ EOF is the second dense region S2, when C and E are interrupted by non-dense faces D, the region corresponding to ∠ COE is the non-dense region, ∠ AOC and ∠ EOF are both dense angular ranges, and ∠ COE is a non-dense angular range.
To this end, the controller will control the rotating speed V2 of the bladeless fan body in the dense angle range to be less than the rotating speed V1 of the bladeless fan body in the non-dense angle range, and because the users gather in the dense angle range, a larger air volume or longer air volume is needed for blowing.
Further, the relationship between V2 and V1 can be set to satisfy V2/V1- β 2/β 1, where β 2 is an average value of the angle differences between the deflection angles of two adjacent faces in the dense angle range, and β 1 is the preset angle difference.
As shown in fig. 3, the average value of the angle differences between the deflection angles of the adjacent faces in the first dense area S1 is the average value of the ∠ AOB angle value and the ∠ BOC angle value, the average value of the angle differences between the deflection angles of the adjacent faces in the second dense area S2 is ∠ EOF, and in the first dense area S1, the ratio of V2 to V1 is the ratio of the average value of ∠ AOB angle value and the average value of ∠ BOC angle value to the preset angle difference, then in the first dense area S2, the ratio of V2 to V1 is the ratio of ∠ EOF angle value to the preset angle difference, if the ratio of the average value of ∠ AOB angle value and the ∠ BOC angle value to the preset angle difference is 0.5, then the ratio of V2 to V1 is also 0.5, and the time in the first dense area S1 is equivalent to the time in the same size range as the non-dense area, and the time is more reasonably set to meet the user demand.
In one embodiment, a maximum deflection angle and a minimum deflection angle are recorded in each rotation period, and when the maximum deflection angle obtained in the latest period is different from the maximum deflection angle recorded in the previous period, or the minimum deflection angle obtained in the latest period is different from the minimum deflection angle recorded in the previous period, or both the two deflection angles are different, it is indicated that the position of the user is changed. The controller updates the determined maximum deflection angle and the determined minimum deflection angle to be the latest acquired maximum deflection angle and minimum deflection angle respectively, and then adjusts the maximum deflection angle and the minimum deflection angle along with the change of the position of a user to drive the bladeless fan body to rotate only between the latest acquired maximum deflection angle and minimum deflection angle in the next rotation period. The maximum deflection angle and the minimum deflection angle can be automatically adjusted along with the rotation period, so that the requirements of users can be met, and the user experience is improved.
In the above embodiment, the camera 31 can automatically focus to clearly shoot a face image when shooting, and since the placement position of the bladeless fan is usually fixed, after multiple times of shooting, the shooting parameters of the camera 31, such as the focal length and the exposure value, which need to be adjusted, have a relatively fixed range, so that the shooting parameters can be adjusted only within the fixed range to shoot. The advantage of this is that invalid faces which are not in the range of use of the user can be effectively filtered out, so as to prevent the invalid faces from interfering the operation of the bladeless fan. For example, when the bladeless fan is used in a large living room, the ideal use distance of the bladeless fan is a user in sand, and for a user far away from the sand and within the image pickup range, the camera 31 may capture the face of the user, but since the bladeless fan is too far away from the sand, the bladeless fan will not have a use meaning for the user, and therefore, invalid faces need to be screened.
Considering that the use distance of the user may have an influence on some parameter values, for example, the angle difference between two users may decrease as the use distance increases, a recommended use distance may be indicated on the product for the user to use at the recommended use distance.
Of course, an infrared distance meter equidistant measurement device can be arranged on the bladeless fan to detect the distance from the user to the bladeless fan. As described above, the placement position of the bladeless fan is usually fixed, the distance from the bladeless fan to the user has a relatively fixed distance range, a mapping relationship between the use distance and the preset parameters can be established, and different use distances are established.
In order to further enrich the user's choices and enhance the user experience, the user can control the bladeless fan to turn off the functions of the above embodiments, thereby having only the functions of a conventional bladeless fan.
The foregoing is a more detailed description of the present invention that is presented in conjunction with specific embodiments, and the practice of the invention is not to be considered limited to those descriptions. It will be apparent to those skilled in the art that a number of simple derivations or substitutions can be made without departing from the inventive concept.
