[0034] Embodiments of the present application are described in detail below with reference to examples illustrated in the accompanying drawings, in which the same or similar components are denoted by the same or similar reference numerals throughout. The embodiments described below by reference to the accompanying drawings are exemplary and are intended to explain the present application, and are not to be understood as limiting the present application.

[0035] An air handling device according to an embodiment of the present application and a control method, apparatus and storage medium thereof are described below with reference to the accompanying drawings and specific embodiments.

[0036] It should be noted that, as shown in Figures 1 to 2 the air outlet of the air handling device in the embodiment of the present application is provided with a wind guide component 1, which includes at least one wind guide sheet 11, and when there are a plurality of wind guide sheets 11, the plurality of wind guide sheets 11 are arranged at intervals. The wind guide component further includes a driving device, which includes a resonant actuator 12, and the resonant actuator 12 can drive the wind guide sheet to resonate to achieve turbulence. That is, the resonant actuator 12 has the ability to drive the wind guide sheet to resonate, and when the wind guide sheet resonates, turbulence can be achieved, thereby improving the air outlet wind feeling.

[0037] It can be understood that "resonance" is also called "resonance", and when the frequency of the driving force and the natural frequency of the system are equal, the amplitude of the forced vibration of the system is the largest, which is called resonance. The phenomenon that the amplitude of the oscillation system increases sharply under the action of the periodic external force when the frequency of the external force is the same as or very close to the natural oscillation frequency of the system. The frequency at which resonance occurs is called "resonance frequency". In addition, "natural frequency" is also called "natural frequency", when the object does free vibration, its displacement changes with time according to the sine or cosine law, the frequency of vibration is independent of the initial condition, and only related to the inherent characteristics of the system (such as mass, shape, material, etc.), called natural frequency, its corresponding period is called natural period. The natural frequency has nothing to do with external excitation, and is a kind of inherent property of the structure. Whether the structure is excited by the outside world or not, the natural frequency of the structure exists, but when the outside world has excitation, the structure is vibrated according to the natural frequency. In addition, "free vibration" refers to: after removing the excitation or constraint, the vibration of the mechanical system appears, and the vibration is maintained only by its elastic restoring force. When there is damping, the vibration will gradually decay, and the frequency of free vibration is only determined by the physical properties of the system, which is called the natural frequency of the system.

[0038] In simple terms, when the excitation frequency of the resonant actuator is the same as or close to the natural frequency of the air guide vane, the resonance effect is utilized. The vibration generated by the air guide vane is called resonance, and the amplitude of the air guide vane will increase sharply. Thus, the air guide vane can effectively turbulent the airflow and improve the airflow feel.

[0039] For example, such as Figure 2 As shown, when the resonant actuator is a piezoelectric material component, an alternating voltage is applied in the polarization direction of the piezoelectric material component. At this time, the piezoelectric material component will move in a certain direction (e.g., Figure 1 Periodic mechanical deformation occurs in the direction of vibration (as shown). Resonance (or synchrotron resonance) only occurs when the excitation frequency of the piezoelectric material is equal to or close to the natural frequency of the air guide plate. At this time, the air guide plate (i.e., Figure 1 The amplitude of the vibrating plate shown will increase sharply, so that the air guide plate can effectively turbulent the airflow and improve the airflow feel.

[0040] Optionally, in some embodiments, the resonant frequency of the resonant actuator driving the air guide vane to resonate is greater than or equal to 1Hz. Therefore, the air guide vane can achieve a better turbulence effect, improving the airflow feel. However, the DC brushless motors and stepper motors used in general air conditioners cannot drive the air guide vane to resonate at a frequency greater than 1Hz, and the air guide vane cannot effectively turbulent the airflow to improve the airflow feel.

[0041] It should be noted that there are many ways for a resonant actuator to drive the air guide vane to resonate. For example, a resonant actuator can include an actuator that uses at least one of the following driving forces—electric, magnetic, mechanical, or temperature fields—to achieve reciprocating motion, thus enabling flexible design. For instance, a resonant actuator can include a piezoelectric actuator, employing the inverse piezoelectric effect. The resonant actuator is a piezoelectric sheet, which utilizes the inverse piezoelectric effect to reciprocate and deform, driving the air guide vane to resonate and achieve the purpose of turbulence. The piezoelectric sheet is a sheet formed of piezoelectric material, such as a piezoelectric film. A piezoelectric film is a flexible, lightweight, and highly tough plastic film that can be made into objects of various thicknesses and large areas. It belongs to the category of piezoelectric materials and can be driven by alternating current to produce the inverse piezoelectric effect, thereby driving the air guide vane to resonate.

[0042] However, the present invention is not limited thereto. The resonant actuator can also drive the air guide vane to resonate in other ways, as illustrated below, but the present invention is not limited thereto.

[0043] For example, resonant actuators include electrostrictive actuators, which drive the air guide vanes to resonate through the electrostrictive effect.

[0044] Specifically, the electrostriction effect refers to the phenomenon that an elastic deformation of a dielectric occurs in an electric field. This phenomenon can be explained as follows: when a dielectric is placed in an electric field, the molecules of the dielectric are polarized, and the positive pole of one molecule is connected with the negative pole of another molecule along the direction of the electric field. Due to the mutual attraction of the positive and negative poles, the entire dielectric is contracted in this direction until the internal elastic force and the electric attraction force are balanced. In short, the electrostrictive material can be connected with the guide vane, and the guide vane is driven to resonate by driving the electrostrictive material to deform through alternating current.

[0045] In addition, it should be noted that the difference between the electrostriction effect and the inverse piezoelectric effect is that the inverse piezoelectric effect is a linear response effect of the first order, and can only occur in solid dielectrics without a center of symmetry. The piezoelectric constant is a third-order tensor; the physical property parameter describing the electrostriction effect of an anisotropic dielectric is a fourth-order tensor. Only the electrostriction effect occurs in a non-piezoelectric dielectric; both the piezoelectric effect and the electrostriction effect occur in a piezoelectric body. Generally, the strain caused by the electrostriction effect is several orders of magnitude smaller than the inverse piezoelectric effect of the piezoelectric body.

[0046] For example, the resonant actuator includes a magnetostrictive actuator, which drives the guide vane to resonate through the magnetostrictive effect.

[0047] Specifically, the magnetostrictive effect refers to the fact that when an object is magnetized in a magnetic field, it will be elongated or shortened in the magnetization direction. When the current through the coil changes or the distance from the magnet changes, the ferromagnetic material whose size changes significantly is usually called ferromagnetic material. The size change of the ferromagnetic material is much larger than that of the current magnetostrictive material such as ferrite, and the energy generated is also large, so it is called super-magnetostrictive material.

[0048] Because the length of the magnetostrictive material changes under the action of the magnetic field, it can displace and do work or repeatedly stretch and shorten under the action of the alternating magnetic field, thereby generating vibration. This material can convert electromagnetic energy (or electromagnetic information) into mechanical energy. In short, the magnetostrictive material can be connected with the guide vane, and the guide vane is driven to resonate by driving the magnetostrictive material to deform through the alternating magnetic field.

[0049] For example, the resonant actuator includes a memory alloy actuator, which drives the guide vane to resonate by deforming the shape memory alloy.

[0050] Specifically, shape memory alloys (SMA for short) can undergo martensitic phase transition under the driving of external field (temperature field, stress field, magnetic field, etc.) and exhibit shape memory effect and superelasticity, output force and displacement. It is an advanced intelligent material that integrates temperature sensing and intelligent driving. It has unique shape memory effect, phase transition pseudoelasticity and other characteristics. Shape memory alloys have three characteristics: large deformation; large degree of freedom of displacement direction; and rapid displacement. Therefore, it has the characteristics of large displacement, high power-to-weight ratio, rapid displacement and free direction. In short, the shape memory alloy can be connected with the guide vane, and the temperature field is changed by heating or cooling to drive the guide vane to resonate.

[0051] For example, the resonant actuator includes an electrorheological fluid actuator, which drives the guide vane to resonate by deforming the electrorheological fluid.

[0052] Specifically, electrorheological fluid (ERF for short) is an intelligent material whose viscosity changes with the change of external electric field intensity. Without an electric field, the electrorheological fluid can flow freely like ordinary liquid, and is basically a Newtonian fluid. When the intensity of the external electric field reaches a certain value, the properties of the electrorheological fluid will change significantly, the viscosity of the liquid increases and gradually lacks fluidity, the shear resistance increases, and the liquid quickly converts to a solid-like state. After the electric field is removed, it quickly returns to a liquid. This state change can be achieved in milliseconds, and the conversion is completely reversible. In short, the electrorheological fluid can be connected with the guide vane, and the guide vane is driven to resonate by an alternating electric field.

[0053] For example, the resonant actuator includes a servo actuator, which can be a hydraulic actuator that can convert hydraulic energy from a hydraulic source into mechanical energy, or can be servo-controlled by a displacement sensor or a travel switch provided by the product as needed. The servo actuator is used to execute the command of the main controller, control the speed, direction, displacement and force of the load, and feedback the signal output force to the main controller. It has the characteristics of large output force, accurate running position, small size, etc. In short, the servo actuator can be connected with the guide vane to drive the guide vane to resonate.

[0054] It can be understood that the installation direction of the air guide component at the air outlet position can be adjusted to generate turbulence in different directions, and the vibration frequency and vibration amplitude of the air guide component can be determined according to the fan speed of the air handling device to avoid single air field distribution and poor user experience. In addition, the vibration frequency and vibration amplitude of the air guide component can also be adjusted according to the conversion of the air supply type to achieve different air supply types.

[0055] Figure 3 It is a flowchart of the control method of the air handling device according to an embodiment of the present application.

[0056] As Figure 3 shown, the control method of the air treatment device provided by the embodiment comprises the following steps:

[0057] S10, obtaining the fan rotating speed of the air treatment device.

[0058] Specifically, the air treatment device in the embodiment can obtain the fan rotating speed N of the air treatment device by using the detection circuit. In some embodiments, the real-time rotating speed of the fan can also be obtained by using the wind speed detector.

[0059] S20, determining the operating parameter of the air guide component according to the fan rotating speed, and controlling the air guide component to operate at the operating parameter.

[0060] Specifically, after obtaining the fan rotating speed of the air treatment device, the operating parameter of the air guide component is determined according to the fan rotating speed, and the air guide component is controlled to operate at the operating parameter. For example, the current fan rotating speed N is obtained, and the air guide component is started, and the air guide component is controlled to work at the vibration amplitude A and the vibration frequency f matching the current fan rotating speed N. The vibration amplitude A and the vibration frequency f can be positively correlated with the fan rotating speed N, so as to achieve the disturbance degree corresponding to the air outlet wind speed.

[0061] In some embodiments of the application, the method further comprises: receiving a type of air supply adjustment instruction; updating the operating parameter of the air guide component according to the type of air supply adjustment instruction, and controlling the air guide component to operate at the updated operating parameter.

[0062] Specifically, after the control unit in the air treatment device receives the air supply instruction, the type of air supply in the air supply instruction is first detected, and when it is detected that the type of air supply is a non-mechanical air supply type, the current fan rotating speed is then obtained. Because if it is detected that the type of air supply is a mechanical air supply type, the air guide component does not need to be started or the vibration amplitude and the vibration frequency thereof remain unchanged after being started. After obtaining the current fan rotating speed, the target air guide component to be started is determined according to the current fan rotating speed, and the air guide component is controlled to work at the vibration amplitude and the vibration frequency matching the current fan rotating speed.

[0063] During the operation of the air guide component, the air treatment device can be sent a type of air supply adjustment instruction to further adjust the type of air supply of the air treatment device, the operating parameter of the air guide component is updated according to the type of air supply adjustment instruction, and the air guide component is controlled to operate at the updated operating parameter.

[0064] It should be noted that whether the air supply type is adjusted depends on the user's active selection. For example, the user can further adjust the air supply type according to his own comfort, update the operating parameters of the air guide component according to the air supply type adjustment instruction, and control the air guide component to operate at the updated operating parameters. If the user does not need to further adjust the air supply type, the current type is maintained and the operating parameters are not changed.

[0065] Optionally, in some possible embodiments, a key for sending the air supply type adjustment instruction can be arranged on the control panel of the air handling device (such as a cabinet air conditioner), and the user can click the key on the air handling device to make the controller in the air handling device receive the air supply type adjustment instruction. In other possible embodiments, the user can also send the air supply type adjustment instruction to the air handling device through the remote controller of the air handling device or the application program on the terminal device, so that the controller in the air handling device can receive the instruction issued by the user.

[0066] Further, in some embodiments of the present application, the operating parameters include the vibration amplitude and the vibration frequency of the air guide blade.

[0067] Specifically, the operating parameters include the vibration amplitude and the vibration frequency of the air guide blade. According to different fan speeds, different air supply types can be realized by adjusting the vibration frequency and the vibration amplitude of the air guide blade. For example, by adjusting the vibration frequency and the vibration amplitude of the air guide blade, windless, natural wind, pulsating wind and other air supply types can be realized.

[0068] Among them, the windless wind refers to the airflow with small wind speed and certain turbulence intensity when the wind blows to the user's activity range, and the user in the activity range is difficult to feel or feel the existence of the wind. Natural wind refers to the airflow movement in the natural environment rather than artificial mechanical power, and the characteristic parameters such as wind speed, wind direction, frequency and turbulence intensity change greatly. Natural wind is generally loved by people with soft, changeable, comfortable blowing feeling and good cooling effect. The wind of natural wind feeling has the same characteristics as natural wind. The wind of pulsating wind feeling refers to the airflow output in a wave shape. When the wind of pulsating wind feeling blows to the user, the user can feel that the wind speed changes alternately high and low.

[0069] In some embodiments of the present application, the operation parameters of the air guiding component are updated according to the air supply type adjustment instruction, including: determining the air supply type according to the air supply type adjustment instruction, wherein the air supply type includes at least one of a first preset air supply type, a second preset air supply type and a third preset air supply type; when the air supply type is the first preset air supply type, controlling the air guiding piece to work at a first preset vibration amplitude and a first preset vibration frequency; when the air supply type is the second preset air supply type, controlling the air guiding piece to work at a second preset vibration amplitude and a second preset vibration frequency, wherein the second preset vibration amplitude is smaller than the first preset vibration amplitude, and the second preset vibration frequency is smaller than the first preset vibration frequency; when the air supply type is the third preset air supply type, controlling the air guiding piece to work at a third preset vibration amplitude and a third preset vibration frequency, wherein the third preset vibration amplitude is smaller than the second preset vibration amplitude, and the third preset vibration frequency is greater than the first preset vibration frequency. The first preset air supply type can correspond to a windless air supply type, the second preset air supply type can correspond to a natural wind air supply type, and the third preset air supply type can correspond to a pulsating wind air supply type.

[0070] Specifically, after the controller in the air treatment device receives the air supply type adjustment instruction, the air supply type adjustment instruction in the air supply instruction is first detected, then the air supply type of the air treatment device is determined according to the air supply type adjustment instruction, and the operation parameters of the air guiding piece, i.e. the vibration amplitude and the vibration frequency of the air guiding piece, are determined according to the determined air supply type. It should be noted that the air supply type in the present embodiment includes a first preset air supply type, a second preset air supply type and a third preset air supply type, wherein the first preset air supply type can be a windless type, the second preset air supply type can be a natural wind type, and the third preset air supply type can be a pulsating wind type.

[0071] For example, if the user does not need to further adjust the air supply type, the current fan speed N is obtained, the air guide component is turned on, and the air guide sheet is controlled to work at the vibration amplitude A and the vibration frequency f matched with the current fan speed N. At this time, the operation parameters are the vibration amplitude A and the vibration frequency f, and the operation parameters continue to be maintained. The vibration amplitude A and the vibration frequency f are automatically matched in positive correlation with the fan speed N. If the user needs to further adjust the air supply type, the vibration amplitude and the vibration frequency of the air guide sheet are further adjusted according to the air supply type instruction, and the operation parameters of the air guide component are updated. When the air supply type instruction is the windless type, the air guide sheet is controlled to work at the vibration amplitude A1 and the vibration frequency f1, the operation parameters of the air guide sheet are updated to the vibration amplitude A1 and the vibration frequency f1, and the air guide component is controlled to work at the updated operation parameters; when the air supply mode instruction is the natural wind mode, the air guide sheet is controlled to work at the vibration amplitude A2 and the vibration frequency f2, the operation parameters of the air guide sheet are updated to the vibration amplitude A2 and the vibration frequency f2, and the air guide component is controlled to work at the updated operation parameters; when the air supply mode instruction is the pulsating wind mode, the air guide sheet is controlled to work at the vibration amplitude A3 and the vibration frequency f3, the operation parameters of the air guide sheet are updated to the vibration amplitude A3 and the vibration frequency f3, and the air guide component is controlled to work at the updated operation parameters.

[0072] It should be noted that the first preset vibration amplitude A1 is greater than the second preset vibration amplitude A2, and the first preset vibration frequency f1 is greater than the second preset vibration frequency f2; the second preset vibration amplitude A2 is greater than the third preset vibration amplitude A3, and the third preset vibration frequency f3 is greater than the first preset vibration frequency f1.

[0073] Specifically, under different wind speed conditions, the vibration amplitudes and the vibration frequencies corresponding to the first preset air supply type, the second preset air supply type and the third preset air supply type are different. For example, the wind speed can be divided into a plurality of different wind speed grades, each wind speed grade has a corresponding vibration amplitude range and a vibration frequency range, and the first preset air supply type, the second preset air supply type and the third preset air supply type under the wind speed grade select specific vibration amplitudes and vibration frequencies in the corresponding vibration amplitude range and vibration frequency range.

[0074] In some embodiments of the application, when the air supply type adjustment instruction is received, or after the air handling device adjusts the fan speed, the fan speed of the air handling device is obtained.

[0075] Specifically, in the embodiment, receiving the air supply type adjustment instruction includes receiving an instruction that the air supply mode is the first preset air supply type, the second preset air supply type, or the third preset air supply type, that is, determining the non-mechanical air supply type. When the air handling device detects that the air supply type is the non-mechanical air supply type, it indicates that the air guide component is not operated at a fixed vibration amplitude and vibration frequency, but is adjusted according to the fan speed. Therefore, when it is detected that the air handling device opens the non-mechanical air supply type, the current fan speed is obtained, the air guide component is opened, the air guide piece is controlled to operate at a vibration amplitude and a vibration frequency matched with the current fan speed, and the mode is operated. If the user further adjusts the air volume, after the air handling device adjusts the fan speed, the fan speed of the air handling device needs to be reacquired, and the air guide piece is controlled to operate at a vibration amplitude and a vibration frequency matched with the reacquired fan speed.

[0076] Further, in some embodiments of the application, the control method of the air handling device further comprises: receiving an air volume adjustment instruction; and controlling the air handling device to adjust the fan speed according to the air volume adjustment instruction.

[0077] Specifically, when the user further adjusts the air volume, the fan speed is adjusted according to the air volume adjustment instruction. At this time, the fan speed of the air handling device changes, the current fan speed needs to be reacquired, and the air guide piece is controlled to operate at a vibration amplitude and a vibration frequency matched with the reacquired fan speed.

[0078] In some embodiments of the application, the control method of the air handling device further comprises: when it is detected that the air handling device opens the fourth preset air supply type, prohibiting the air guide component from being opened.

[0079] Specifically, the fourth preset air supply type in the embodiment is the mechanical air supply type, that is, when the air handling device opens the mechanical air supply type, the air guide component is prohibited from being opened. Since in the mechanical air supply type, only the mechanical air supply of the air handling device is required, and no wind feeling, natural wind, etc. is required, in order to improve the service life of the air guide component and reduce the operating power consumption of the air handling device, the air guide component is directly prohibited from being opened when the air handling device opens the fourth preset air supply type. More specifically, the mechanical air supply mode can include: directional air supply, air guide plate swing air supply, etc.

[0080] It should be noted that in addition to the above-mentioned air supply types, other types of air supply types can be provided to improve the air supply types of the air handling device. The specific types of air supply types and the number of air supply types are not limited here and can be set by the user or the manufacturer.

[0081] As a specific example of the application, as shown inFigure 4 As shown in the figure Figure 4 is a flow chart of a control method of an air handling device according to an embodiment of the present application, which can include the following steps:

[0082] S401, start.

[0083] S402, receive the start instruction of the air supply mode.

[0084] S403, whether it is a mechanical air supply instruction. If yes, jump to step S411. If no, jump to step S404.

[0085] S404, get the current fan speed N.

[0086] S405, start the air guide component and control the air guide sheet to work with the vibration amplitude A and vibration frequency f matched with the current fan speed N.

[0087] S406, judge whether further adjustment of the air supply type is needed. If yes, jump to step S407-S409 according to the adjusted air supply type. If the user selects the air supply type as the windless type, go to step S407; if the user selects the air supply type as the natural wind type, go to step S408; if the user selects the air supply type as the pulsating wind type, go to step S409. If no, jump to step S410.

[0088] S407, windless type, control the air guide sheet to work with the vibration amplitude A1 and vibration frequency f1.

[0089] S408, natural wind type, control the air guide sheet to work with the vibration amplitude A2 and vibration frequency f2, wherein A1>A2, f1>f2.

[0090] S409, pulsating wind type, control the air guide sheet to work with the vibration amplitude A3 and vibration frequency f3, wherein A2>A3, f3>f1.

[0091] S410, judge whether the air volume needs to be adjusted. If yes, jump to S413. If no, jump to S411.

[0092] S411, maintain the current mode running.

[0093] S412, do not start the air guide component.

[0094] S413, adjust the fan speed according to the air volume adjustment instruction.

[0095] It should be noted that the step 401 above can be specifically calling the control program of the air handling device, so as to trigger the control method of the air handling device to start execution.

[0096] The effectiveness of the control method of the air handling equipment of the present invention is illustrated below through simulation test results. In the simulation experiments, the air supply type of the air handling equipment was controlled as mechanical air supply, windless type, natural wind type, and pulsed wind type, as shown in Figures 5(a), 5(b), 5(b'), 5(c), 5(c'), 5(d), and 5(d'). Figure 5(a) shows the air outlet situation of the mechanical air supply type; Figures 5(b) and 5(b') show the air outlet situation of the windless type at different times; Figures 5(c) and 5(c') show the air outlet situation of the natural wind type at different times; and Figures 5(d) and 5(d') show the air outlet situation of the pulsed wind type at different times. It should be noted that in Figure 5, the direction pointed to by the arrow is the flow direction of the airflow output by the air handling equipment through the air outlet.

[0097] The simulation results show that in the mechanical air supply type, the airflow is smooth along the flow direction; in the windless type, when the air guide component is controlled by the first preset vibration amplitude and frequency, the airflow fluctuates significantly in the plane along the vibration direction of the air guide component; in the natural wind type, when the air guide component is controlled by the second preset vibration amplitude and frequency, the airflow also fluctuates significantly in the plane along the vibration direction of the air guide component, and the airflow is relatively evenly dispersed, similar to natural wind. In the pulsating wind type, when the air guide component is controlled by the third preset vibration amplitude and frequency, the airflow diffuses in a pulse shape in the plane along the vibration direction of the air guide component.

[0098] Furthermore, analysis of wind speed time series diagrams revealed that, as Figure 6 As shown, in the mechanical wind type, i.e., when the air guide component is not turned on, the wind speed remains basically unchanged over time, which is consistent with the simulation results shown in Figure 5(a) above, making it suitable for long-distance air delivery; in the windless type, i.e., when the air guide component is controlled to work with the first preset vibration amplitude and the first preset vibration frequency, the wind speed is relatively small and has a certain turbulence intensity, so as to better provide users with a windless feeling, which is consistent with the simulation results shown in Figure 5(b) or Figure 5(b') above; in the natural wind type, i.e., with the second preset vibration amplitude and the second preset vibration frequency... When the frequency-controlled air guide component is working, the wind speed changes without a fixed pattern, and the turbulence intensity is greater, so that the air handling equipment can provide more realistic natural wind. This is consistent with the simulation results shown in Figure 5(c) or Figure 5(c'). In the pulsed wind type, that is, when the air guide component is controlled by the third preset vibration amplitude and the third preset vibration frequency, the wind speed changes more regularly and is pulsed overall, so that the air handling equipment can provide pulsed wind. This is consistent with the simulation results shown in Figure 5(d) or Figure 5(d').

[0099] From the simulation results, it can be seen that when the air guide component is opened, the distribution of the indoor wind field can be effectively changed, so that different air supply modes are realized, and different wind feelings and experiences are brought to the user.

[0100] In conclusion, the control method of the air treatment equipment according to the embodiment of the application can make the air guide component arranged at the air outlet work with different operation parameters according to different fan speeds, so as to avoid the problem of single wind field distribution, and has simple control logic, easy implementation and high applicability.
