Description

Technical Field

[0001] The present invention relates to the field of electrical equipment, and in particular to an air treatment device, a control method and a storage medium. Background Art

[0002] At present, in order to create a strong and weak alternating pulsating wind feeling, the existing air conditioner usually adjusts the speed of the fan wheel, for example, the speed of the fan wheel is switched between high and low speeds in turn. The fan wheel is directly driven by a motor.

[0003] In order to create a pulsating wind feeling, the motor speed needs to change rapidly and alternately. Existing ordinary motors cannot respond quickly to create a clear pulsating wind feeling.

[0004] The rapid change of motor speed leads to the rapid change of wind wheel speed, which produces a large abnormal noise and increases the noise value of the whole machine when the air conditioner is running.

[0005] When the motor drives the wind wheel, the speed changes rapidly, so the motor and wind wheel are easily damaged, their service life is greatly reduced, and their reliability is reduced.

[0006] Since the rotation speed of the fan wheel directly affects the air volume of the air conditioner, the rotation speed of the fan wheel will affect the cooling capacity of the air conditioner when it switches between high and low speeds, increasing the difficulty of regulating the cooling capacity of the air conditioner.

[0007] Therefore, adjusting the speed of the fan's impeller to create a pulsating wind sensation places too high demands on the motor's performance, generates too much noise, and reduces product reliability. Summary of the invention

[0008] The technical problem to be solved by the present invention is that the existing air conditioner has a poor wind effect of creating a pulsating wind feeling by adjusting the speed of the fan wheel.

[0009] To achieve the above-mentioned purpose, the present application proposes a control method for an air treatment device, wherein an air outlet of the air treatment device is provided with an air guide component, wherein the air guide component includes one or a plurality of air guide vanes arranged at intervals, and the air guide component also includes a driving device, wherein the driving device includes a resonant actuator, and the resonant actuator can drive the air guide vanes to resonate to achieve turbulence; the control method includes:

[0010] Sending a driving signal to the resonant actuator so that the resonant actuator drives the air guide plate to resonate, wherein the voltage peak value and / or frequency of the driving signal changes periodically;

[0011] The frequency of the driving signal has a value range that is within the resonant frequency range of the air guide component.

[0012] In an exemplary embodiment, sending a driving signal to a resonant actuator so that the resonant actuator drives the air guide plate to resonate includes:

[0013] A plurality of driving signals are cyclically sent to the resonant actuator, wherein the voltage peak value and / or frequency of any two driving signals are different.

[0014] In an exemplary embodiment, the voltage peak values ​​of all types of driving signals are different from each other, and the frequencies of all types of driving signals are the same; or

[0015] The voltage peak values ​​of all types of driving signals are the same, and the frequencies of all types of driving signals are different from each other;

[0016] The voltage peak values ​​of all types of driving signals are different from each other, and the frequencies of all types of driving signals are different from each other.

[0017] In an exemplary embodiment, among the multiple driving signals, a driving signal with a higher frequency has a higher voltage peak value.

[0018] In an exemplary embodiment, the voltage peak values ​​of at least two driving signals are different;

[0019] Among the voltage peaks of all driving signals, the maximum voltage peak is more than twice the minimum voltage peak.

[0020] In an exemplary embodiment, the signal duration of each driving signal is 2 to 20 seconds.

[0021] In an exemplary embodiment, the signal duration of each driving signal is the same; or,

[0022] At least two driving signals have different signal durations.

[0023] In an exemplary embodiment, a driving signal with a higher frequency has a longer signal duration; or

[0024] The higher the frequency of the driving signal, the shorter the signal duration; or

[0025] The signal durations of at least two driving signals with different frequencies are the same.

[0026] In an exemplary embodiment, the signal duration of the driving signal having the first resonant frequency of the air guide component is 7 to 15 seconds; and / or

[0027] The signal duration of the driving signal having the second resonance frequency of the air guide component is 3 to 5 seconds, and the order of the first resonance frequency is higher than the order of the second resonance frequency.

[0028] In an illustrative embodiment, before sending the driving signal to the resonant actuator, the control method further includes:

[0029] Receive user settings on the number of drive signals, the arrangement order of the drive signals, the signal duration of each drive signal, the voltage peak value of each drive signal and / or the frequency of each drive signal.

[0030] The present application also proposes a computer-readable storage medium on which a computer program is stored, wherein when the computer program is executed by a processor, the control method of the air treatment equipment as described above is implemented.

[0031] The present application also proposes an air treatment device, which comprises:

[0032] The housing is provided with an air supply channel and an air outlet arranged at one end of the air supply channel;

[0033] an air guide component, arranged at the air outlet, comprising one or a plurality of air guide plates arranged at intervals and a driving device, wherein the driving device comprises a resonant actuator, and the resonant actuator can drive the air guide plates to resonate to achieve turbulence; and

[0034] The control device is electrically connected to the resonant actuator and the air guide component, and is configured to execute the control method of the air treatment equipment as described above.

[0035] In the technical solution of the present application, when the voltage peak and / or frequency of the driving signal changes periodically, the degree of disturbance of the air flow output from the air outlet by the air guide plate changes periodically, and the degree of softening of the air flow at the air outlet changes periodically, thereby simulating a pulsating wind feeling.

[0036] The air guide vanes of the air guide component redistribute the wind field at the air outlet by resonance to create a pulsating wind. The air guide component has very little resistance to the airflow output from the air outlet and will not affect the air volume at the air outlet of the air handling device. It can process wind of different air volumes to form a pulsating wind. The air guide component makes little noise when working. At the same time, due to the rapid change of the driving signal input to the resonant actuator, the vibration amplitude or vibration frequency of the air guide vanes can change rapidly. Thus, by setting the voltage peak value and / or frequency of the driving signal to a rapid periodic change, the vibration amplitude and / or vibration frequency of the air guide vanes can also change rapidly periodically, and the air handling device can create a pulsating wind with a short change period. The change period of the pulsating wind can reach seconds. BRIEF DESCRIPTION OF THE DRAWINGS

[0050] This embodiment proposes an air treatment device, which can take in and out air, and has unlimited air treatment functions, for example, it can perform at least one of temperature adjustment, humidification, purification, circulation, etc. on the air. The air treatment device includes but is not limited to an air conditioner, and the air treatment device can also be a purifier, a humidifier, a fan, etc. After the specific type of the air treatment device is determined, those skilled in the art can know other components of the air treatment device, which will not be described here.

[0051] like Figure 1 As shown, Figure 1 The structure of an air treatment device 100 in this embodiment is shown. The air treatment device 100 includes a housing 1, an air supply component, an air guide component 2, an adjustment component and a control device.

[0052] The top of the housing 1 is provided with an air inlet, and the bottom of the housing 1 is provided with an air outlet 11. The air outlet 11 can be configured as a strip, or a straight strip. An air supply flow channel is provided in the housing 1, and the two ends of the air supply flow channel are respectively connected to the air inlet and the air outlet 11. The air supply component can be a fan, such as a cross-flow fan, an axial flow fan, or a centrifugal fan.

[0053] The air supply component is arranged on the air supply flow channel, and is used to drive the air in the air supply flow channel to move toward the air outlet 11. When the air supply component is in operation, it can inhale air from the air inlet, flow through the air supply flow channel, and then output from the air outlet 11, so that the air outlet 11 can supply air outward.

[0054] The regulating component can be arranged on the air supply flow channel. The regulating component can be a temperature regulating component, a humidity regulating component or a purification component. The temperature regulating component is used to regulate the temperature of the air flow passing through, the humidity regulating component is used to regulate the humidity of the air flow passing through, and the purification component temperature regulating component is used to filter and purify the air flow passing through.

[0055] In this embodiment, the regulating component is a temperature regulating assembly, the temperature regulating assembly includes a first heat exchanger, and the air handling device 100 also includes a second heat exchanger and a compressor. The first heat exchanger is used to exchange heat with indoor air. The second heat exchanger is used to exchange heat with outdoor air. The compressor, the first heat exchanger and the second heat exchanger are connected to each other through a refrigerant pipeline. The compressor can drive the refrigerant to circulate between the first heat exchanger and the second heat exchanger, thereby realizing indoor and outdoor air heat exchange.

[0056] The first heat exchanger can be arranged on the air supply channel. The airflow exchanges heat with the first heat exchanger when flowing through the first heat exchanger. When the air handling device is in the heating mode, the first heat exchanger transfers heat to the airflow, so that the air outlet 11 can convey hot air to the outside. When the air handling device is in the cooling mode, the first heat exchanger transfers cold air to the airflow, so that the air outlet 11 can convey cold air to the outside.

[0057] like Figure 1 , 2 As shown, the air guide component 2 is arranged at the air outlet 11, and the air guide component 2 is used to disturb the wind sent out by the air supply component. The air guide component 2 serves as an air supply terminal device of the air handling equipment to regulate the wind feel of the air supply. The air guide component 2 includes a plurality of air guide components 21 and a connector 22. The connector 22 is configured as a strip, which may be a straight strip. The connector 22 is connected to the housing 1, and the extension direction of the connector 22 is the same as the extension direction of the air outlet 11. A plurality of air guide components 21 are connected to the connector 22, and are arranged in sequence along the connector 22.

[0058] like Figure 3As shown, the air guide assembly 21 includes a driving device 211 and an air guide plate 212. The driving device 211 is respectively connected to the connecting member 22 and the air guide plate 212. The connecting member 22 and the air guide plate 212 are respectively arranged on opposite sides of the driving device 211. The air guide plate 212 is constructed as a sheet structure. One end of the air guide plate 212 is connected to the driving device 211. The connecting member 22 can be connected above the air outlet 11, and the air guide plate 212 is located at the front end of the air outlet 11. The plate surface of the air guide plate 212 is perpendicular to the extension direction of the air outlet 11. A plurality of air guide assemblies 21 are arranged in sequence along the extension direction of the air outlet 11, and the intervals between two adjacent air guide assemblies 21 can be the same. The air guide plate 212 is used at the air outlet 11 at the air supply end of the air handling equipment to regulate the wind feeling, thereby achieving the adjustment of the air outlet effect.

[0059] The driving device 211 includes a resonant actuator. The resonant actuator can drive the air guide plate 212 to resonate to achieve turbulence. In other words, the resonant actuator has the ability to drive the air guide plate 212 to resonate. When the air guide plate 212 resonates, turbulence can be achieved, thereby improving the wind feeling of the air outlet. The resonant actuator can be connected to one end of the air guide plate 212.

[0060] It is understandable that "resonance" is also called "resonance". When the frequency of the driving force is equal to the natural frequency of the system, the amplitude of the forced vibration of the system is the largest. This phenomenon is called resonance. When the frequency of the external force is the same as or very close to the natural oscillation frequency of the system, the amplitude of the oscillation system increases sharply under the action of periodic external forces. The frequency when resonance occurs is called "resonance frequency". In addition, "natural frequency" is also called "natural frequency". When an object vibrates freely, its displacement changes with time according to the sine or cosine law. The frequency of vibration has nothing to do with the initial conditions, but is only related to the inherent characteristics of the system (such as mass, shape, material, etc.). It is called the natural frequency, and its corresponding period is called the natural period. The natural frequency has nothing to do with external excitation and is an inherent property of the structure. Regardless of whether the structure is excited by the outside world, the natural frequency of the structure exists. It is just that when there is external excitation, the structure produces a vibration response according to the natural frequency. In addition, "free vibration" refers to the vibration that occurs in a mechanical system after the excitation or constraint is removed. The vibration is maintained only by its elastic restoring force. When there is damping, the vibration gradually decays. The frequency of free vibration is determined only by the physical properties of the system itself, which is called the natural frequency of the system.

[0061] 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 component 2, the resonance effect is utilized, and the vibration generated by the air guide piece 212 is called resonance. The amplitude of the air guide piece 212 will increase sharply, so that the air guide piece 212 can more effectively disturb the flow and improve the wind feeling. The resonant frequency of the air guide component 2 is determined by the resonant actuator and the air guide piece 212. The size of the resonant actuator will affect the overall resonant frequency.

[0062] The resonant actuator is a piezoelectric material. A piezoelectric material is a device that uses the inverse piezoelectric effect of piezoelectric materials to convert electrical energy into mechanical energy output. When an alternating voltage peak is applied to the polarization direction of the piezoelectric material, the piezoelectric material will move in a certain direction (such as Figure 3 When the excitation frequency of the piezoelectric material is equal to or close to the natural frequency of the wind guide component 2, resonance (or resonance) occurs. At this time, the wind guide piece 212 (i.e. Figure 3 The amplitude of the vibration sheet (as shown) will increase sharply, so that the air guide sheet 212 can more effectively disturb the air flow and improve the wind feeling of the air outlet.

[0063] In some embodiments, the resonant frequency of the resonant actuator driving the air guide 212 to resonate is greater than or equal to 1 Hz. As a result, the air guide 212 can achieve a better turbulence effect and improve the wind feel of the air. However, the DC brushless motor and stepper motor used in general air conditioners cannot drive the air guide 212 to resonate with a resonant frequency greater than 1 Hz, and the air guide 212 cannot effectively turbulently improve the wind feel of the air.

[0064] The piezoelectric material piece may be a piezoelectric actuator or a piezoelectric sheet, for example, a piezoelectric ceramic. An alternating voltage peak is applied to the polarization direction of the piezoelectric material piece, and the piezoelectric material piece is deformed back and forth by utilizing the inverse piezoelectric effect of the piezoelectric material piece, thereby driving the air guide piece 212 to resonate and achieve the purpose of turbulence. The piezoelectric sheet is a sheet-like body formed by a piezoelectric material, such as a piezoelectric film. The piezoelectric film is a flexible, lightweight, and highly tough plastic film that can be made into objects of various thicknesses and larger areas. It is a type of piezoelectric material piece, and the piezoelectric film can be driven by alternating current to produce an inverse piezoelectric effect, thereby driving the air guide piece 212 to resonate.

[0065] It should be noted that there are many ways for the resonant actuator to drive the air guide blade 212 to resonate. For example, the resonant actuator may include an actuator that uses at least one of electrical, magnetic, mechanical, and temperature fields to achieve reciprocating motion, thereby achieving flexible design. For example, the resonant actuator may include a piezoelectric actuator that uses the inverse piezoelectric effect. The resonant actuator is a piezoelectric sheet that uses the inverse piezoelectric effect of the piezoelectric sheet to reciprocate and deform, driving the air guide blade 212 to resonate, thereby achieving the purpose of turbulence. Among them, the piezoelectric sheet is a sheet formed of piezoelectric material, such as a piezoelectric film. The piezoelectric film is a flexible, lightweight, and highly tough plastic film that can be made into objects of various thicknesses and larger areas. It is a type of piezoelectric material. The piezoelectric film can be driven by alternating current to produce the inverse piezoelectric effect, thereby driving the air guide blade 212 to resonate.

[0066] However, the present invention is not limited thereto, and the resonant actuator may also drive the air guide plate 212 to resonate in other ways, such as described in the following example, but the present invention is not limited thereto.

[0067] For example, the resonant actuator includes an electrostrictive actuator, which drives the air guide piece 212 to resonate through the electrostrictive effect.

[0068] Specifically, the electrostrictive effect refers to the phenomenon that a dielectric undergoes elastic deformation in an electric field. This phenomenon can be explained as follows: when a dielectric is placed in an electric field, its molecules are polarized, and along the direction of the electric field, the positive pole of one molecule connects with the negative pole of another molecule. Since the positive and negative poles attract each other, the entire dielectric shrinks in this direction until the elastic force inside it is balanced with the electric attraction. In short, the electrostrictive material can be connected to the air guide 212, and the electrostrictive material can be deformed by alternating current, thereby driving the air guide 212 to resonate.

[0069] In addition, it should be noted that the difference between the electrostrictive effect and the inverse piezoelectric effect is that the inverse piezoelectric effect is a linear response effect of the first order term, which can only appear in solid dielectrics without a symmetry center. The piezoelectric constant is a third-order tensor; the physical parameter describing the electrostrictive effect of anisotropic dielectrics is a fourth-order tensor. Only the electrostrictive effect appears in non-piezoelectric dielectrics; the piezoelectric effect and the electrostrictive effect appear simultaneously in piezoelectric bodies. Generally, the strain caused by the electrostrictive effect is several orders of magnitude smaller than the inverse piezoelectric effect of piezoelectric bodies.

[0070] For example, the resonant actuator includes a magnetostrictive actuator, which drives the air guide plate 212 to resonate through the magnetostrictive effect.

[0071] Specifically, the magnetostrictive effect refers to the fact that when an object is magnetized in a magnetic field, it will stretch or shorten in the magnetization direction. When the current passing through the coil changes or the distance from the magnet changes, the size of the ferromagnetic material changes significantly. This is usually called a ferromagnetostrictive material. Its size change is much greater than that of current magnetostrictive materials such as ferrites, and the energy generated is also large, so it is called a giant magnetostrictive material.

[0072] Since the magnetostrictive material changes its length under the action of a magnetic field, it can be displaced to do work or can be repeatedly stretched and shortened under the action of an alternating magnetic field, thereby generating vibrations. This material can convert electromagnetic energy (or electromagnetic information) into mechanical energy. In short, the magnetostrictive material can be connected to the air guide 212, and the magnetostrictive material can be deformed by the alternating magnetic field, thereby driving the air guide 212 to resonate.

[0073] For example, the resonant actuator includes a shape memory alloy actuator, which drives the air guide plate 212 to resonate by deforming the shape memory alloy.

[0074] Specifically, shape memory alloys (Shape Memory Alloys): SMA for short, can undergo martensitic phase transformation under the drive of external fields (temperature fields, stress fields, magnetic fields, etc.) to exhibit shape memory effect and superelasticity, output force and displacement to the outside, and are advanced intelligent materials that integrate temperature perception and intelligent drive, with unique shape memory effect, phase change pseudo-elasticity and other characteristics. Shape memory alloys have three characteristics: large deformation; large degree of freedom in displacement direction; displacement can occur rapidly. 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 to the air guide 212, and the temperature field can be changed by heating or cooling to drive the air guide 212 to resonate.

[0075] For example, the resonant actuator includes an electrorheological fluid actuator, which drives the air guide blade 212 to resonate by deforming the electrorheological fluid.

[0076] Specifically, electrorheological fluid (ERF for short) is a smart material whose viscosity changes with the strength of an applied electric field. In the absence of an electric field, the electrorheological fluid can flow freely like an ordinary liquid, and is basically a Newtonian fluid. When the strength of the applied electric field reaches a certain value, the properties of the electrorheological fluid will change significantly, the viscosity of the liquid will increase and gradually lack fluidity, the shear resistance will increase, and it will quickly transform from a liquid to a quasi-solid state, and quickly return to a liquid after the electric field is removed. This state change can be achieved in just milliseconds, and this transformation is completely reversible. In short, the electrorheological fluid can be connected to the air guide plate 212, and the air guide plate 212 can be driven to resonate by an alternating electric field.

[0077] 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, and can also be servo-controlled through a displacement sensor or travel switch provided with the product as needed. It is used to execute the command of the main controller, control the speed, direction, displacement, and force of the load, and at the same time feedback the signal to the main controller, and has the characteristics of large output force, accurate operating position, and small size. In short, the servo actuator can be connected to the air guide plate 212 to drive the air guide plate 212 to resonate.

[0078] It is understandable that the vibration direction of the air guide piece 212 can be adjusted by changing the installation direction of the air guide piece 212 at the air outlet position, thereby performing turbulence in different directions. The control method of this embodiment can make the air handling device generate wind with different wind senses by controlling each air guide group to work in the same or different turbulence modes, thereby improving the user experience, and when there are many people in the space where the air handling device is located, different wind senses can be provided to different users, thereby providing air-conditioning wind to users in a more targeted manner.

[0079] In some embodiments, the resonant frequency of the resonant actuator driving the air guide plate 212 to resonate is greater than or equal to 1 Hz. Therefore, the air guide plate 212 can achieve a better turbulence effect and improve the wind feeling of the air outlet.

[0080] The resonant frequency of the resonant actuator driving the air guide piece 212 to resonate is 1 Hz-100 Hz. That is, a resonant actuator with a resonant frequency of 1 Hz-100 Hz (e.g., 1 Hz, 10 Hz, 20 Hz, 30 Hz, 40 Hz, 50 Hz, 60 Hz, 70 Hz, 80 Hz, 90 Hz, 100 Hz, etc.) can be selected as needed to drive the air guide piece 212 with a matching natural frequency to resonate, thereby meeting different requirements for airflow feel.

[0081] Furthermore, a resonant actuator with a resonant frequency of 10Hz-80Hz (e.g., 10Hz, 20Hz, 30Hz, 40Hz, 50Hz, 60Hz, 70Hz, 80Hz, etc.) can be selected to drive the air guide piece 212 with a matching natural frequency to resonate, thereby meeting different requirements for airflow feel. Of course, the present invention is not limited to this. In other embodiments, the resonant frequency of the resonant actuator driving the air guide piece 212 to resonate can also be greater than 100Hz, which will not be described in detail here.

[0082] The resonant actuator is a piezoelectric material. When an alternating voltage peak is applied in the polarization direction of the piezoelectric material, the piezoelectric material will undergo an inverse piezoelectric effect and produce periodic mechanical deformation in a certain direction. Resonance (or resonance) occurs only when the excitation frequency of the piezoelectric material is equal to or close to the natural frequency of the air guide component 2. At this time, the vibration amplitude of the air guide piece 212 will increase sharply, so that the air guide piece 212 can more effectively disturb the airflow and improve the wind feel of the air outlet.

[0083] The control device is electrically connected to the air supply component, the air guide component 2 and the adjustment component. The control device is electrically connected to the opposite ends of the resonant actuator in the polarization direction. The control device controls the vibration amplitude and vibration frequency of the resonant actuator driving the air guide plate 212 to swing by sending a drive signal to the resonant actuator. The drive signal can be a voltage peak pulse signal, and the voltage peak pulse signal can be an AC voltage signal.

[0084] The control device controls the vibration amplitude of the air guide plate 212 by controlling the voltage peak amplitude of the driving signal. When the air outlet speed of the air handling device is the same, the greater the absolute value of the voltage peak of the driving signal, the greater the amplitude at which the resonant actuator drives the air guide plate 212 to swing when receiving the driving signal.

[0085] The control device controls the vibration frequency of the air guide blade 212 by controlling the frequency of the driving signal. For example, when the driving signal is a pulse voltage signal, the resonant actuator receives a pulse of the driving signal and drives the air guide blade 212 to swing to one side once. The swing direction is determined by the positive and negative of the pulse. When the pulse is a positive pulse, the air guide blade 212 swings to one side, and when the pulse is a negative pulse, the air guide blade 212 swings to the other side.

[0086] The control device can control the resonant actuator to swing the air guide plate 212 at a preset vibration amplitude and a preset frequency by sending a driving signal to the resonant actuator, so as to realize that the air treatment device outputs wind with different wind sensations. When the air guide plate 212 vibrates at different vibration frequencies and / or different vibration amplitudes, the air guide component 2 can process the airflow output by the air outlet 11 to form wind with different wind sensations, and the wind with different wind sensations has different wind speeds and / or turbulence. The air treatment device outputs wind with different wind sensations in different air supply modes. For example, after processing the airflow output by the air outlet 11, the air guide component 2 can simulate wind with a natural wind sensation, wind without a wind sensation, and wind with a pulsating wind sensation.

[0087] like Figure 4 As shown, this embodiment also proposes a control method for air treatment equipment, which is implemented based on the above air treatment equipment. The control method includes:

[0088] Step S1: The control device receives a wind sense adjustment instruction and proceeds to step S2;

[0089] The air supply component is in operation so that the air outlet of the air handling device supplies air outward. The air volume of the air outlet can be freely set by the user. For example, the air handling device has multiple air volume gears, and different air volume gears correspond to different air volumes of the air outlet. The user can select one of the air volume gears to set the air volume of the air outlet.

[0090] The user can send the wind sense adjustment instruction to the control device of the air handling device through a remote control or a mobile terminal, and the mobile terminal can be a mobile phone, a tablet computer or a smart speaker. The wind sense adjustment instruction is used to instruct the resonant actuator to drive the air guide plate 212 to resonate, so as to adjust the airflow output from the air outlet of the air handling device to have a pulsating wind sense.

[0091] Step S2: the control device sends a driving signal to the resonant actuator so that the resonant actuator drives the air guide plate 212 to resonate, and the voltage peak value and / or frequency of the driving signal changes periodically.

[0092] The driving signal is a pulse voltage signal, preferably an AC voltage signal. The control device sends the driving signal to the resonant actuator, and the resonant actuator deforms due to the inverse piezoelectric effect when receiving the driving signal, and drives the air guide plate 212 to vibrate through the deformation of the resonant actuator itself. The resonant frequency of the air guide component 2 usually has multiple resonant frequencies, which are arranged in order from small to large. The resonant frequencies of the air guide component 2 are respectively the first-order resonant frequency, the second-order resonant frequency, the third-order resonant frequency... and the n-th order resonant frequency. The air guide plate 212 is preferably an air guide plate 212 whose first-order resonant frequency and the second-order resonant frequency are both within 100Hz. The value range of the frequency of the driving signal is the range of the resonant frequency of the air guide component 2. The frequency of the driving signal is equal to any one of the first-order resonant frequency to the n-th order resonant frequency, preferably equal to the first-order resonant frequency. The resonant actuator drives the air guide plate 212 to swing at the same frequency as the driving signal, and the excitation frequency of the excitation applied by the resonant actuator to the air guide plate 212 is equal to the resonant frequency of the air guide component 2, then the air guide plate 212 resonates.

[0093] The voltage peak value and / or frequency of the driving signal are controlled to change periodically, and the change period of the voltage peak value and / or frequency is greater than the pulse period of a single pulse of the driving signal.

[0094] The voltage peak value of the driving signal is positively correlated with the deformation amplitude of the resonant actuator, and the deformation amplitude of the resonant actuator is positively correlated with the vibration amplitude of the air guide piece 212. When the voltage peak value of the driving signal changes periodically, the degree of disturbance of the airflow output from the air outlet by the air guide piece 212 changes periodically, that is, the resonance of the air guide piece 212 causes the wind speed and / or turbulence of the airflow to change periodically, and therefore, the softening degree of the airflow at the air outlet changes periodically, thereby simulating the wind with a pulsating wind feeling.

[0095] The frequency of the driving signal is the same as the excitation frequency of the resonant actuator on the air guide plate 212, that is, the same as the vibration frequency of the air guide plate 212. When the frequency of the driving signal changes periodically, the degree of disturbance of the airflow output from the air outlet by the air guide plate 212 changes periodically, that is, the resonance of the air guide plate 212 causes the wind speed and / or turbulence of the airflow to change periodically, and therefore, the softening degree of the airflow at the air outlet changes periodically, thereby simulating the wind with a pulsating wind feeling.

[0096] Similarly, when the voltage peak and frequency of the driving signal change periodically synchronously, the degree of disturbance of the airflow output from the air outlet by the air guide plate 212 changes periodically, and the degree of softening of the airflow at the air outlet changes periodically, thereby simulating a pulsating wind feeling.

[0097] The air guide piece 212 of the air guide component 2 redistributes the wind field at the air outlet by resonance to create a pulsating wind. The air guide component 2 has very little resistance to the airflow output from the air outlet and will not affect the air volume at the air outlet of the air treatment device. Winds of different air volumes can be processed to form pulsating wind. At the same time, since the rapid change of the driving signal input to the resonant actuator can cause the vibration amplitude or vibration frequency of the air guide piece 212 to change rapidly, by setting the voltage peak value and / or frequency of the driving signal to a rapid periodic change, the vibration amplitude and / or vibration frequency of the air guide piece 212 can also change rapidly periodically, and the air treatment device can create a pulsating wind with a short change period. The change period of the pulsating wind can reach the second level.

[0098] In an exemplary embodiment, step S2 includes: cyclically sending a plurality of driving signals to the resonant actuator, wherein the voltage peak values ​​and / or frequencies of any two driving signals are different.

[0099] The plurality of driving signals are all pulse voltage signals. The number of types of driving signals is greater than or equal to 2. The driving signals may be two, three, four or five. At least one of the voltage peak value and the frequency is different between different types of driving signals.

[0100] The voltage peak values ​​of the multiple driving signals may be the same, but the frequencies of the multiple driving signals are respectively equal to the resonance frequencies of different orders of the air guide component 2 .

[0101] The voltage peak values ​​of the multiple driving signals may be different from each other, but the frequencies of the multiple driving signals are all the resonance frequencies of the same order of the air guide component 2 .

[0102] The voltage peak values ​​of the multiple driving signals may be different from each other, and the frequencies of the multiple driving signals may be equal to the resonance frequencies of different orders of the air guide component 2 .

[0103] A plurality of driving signals are sent to the resonant actuator cyclically, and in each cycle, the plurality of driving signals are sent to the resonant actuator in the same order. Since at least one of the voltage peak value and the frequency between different types of driving signals is different, after receiving different types of driving signals, the resonant actuator drives the air guide plate 212 to vibrate with different vibration amplitudes and / or different vibration frequencies, so that the air handling device outputs wind with different softening degrees in one cycle.

[0104] In an exemplary embodiment, among all types of driving signals, at least two driving signals have different voltage peak values. It may be that the voltage peak values ​​of different types of driving signals are all different.

[0105] Among the voltage peaks of all the driving signals, the largest voltage peak is at least twice the smallest voltage peak. The largest voltage peak is preferably 2 to 3 times the smallest voltage peak.

[0106] Since there is a positive correlation between the voltage peak of the driving signal and the vibration amplitude of the air guide plate 212, when the maximum voltage peak is more than twice the minimum voltage peak, the difference in the vibration amplitude of the air guide plate 212 when the driving signal with the maximum voltage peak and the driving signal with the minimum voltage peak are respectively transmitted to the resonant actuator is large enough to allow the user to clearly feel the large difference in the degree of softening of the wind, thereby making the switching between strong and weak winds more obvious, and the pulsation of the wind stronger, thereby enhancing the user experience.

[0107] In an exemplary embodiment, among all driving signals, the driving signal with a larger frequency has a larger voltage peak value. The frequency of the driving signal and the voltage peak value of the driving signal may be positively correlated.

[0108] The smaller the frequency of the driving signal, the smaller its voltage peak value is. When the driving signal drives the resonant actuator to drive the air guide plate 212 to vibrate, the vibration amplitude and vibration frequency of the air guide plate 212 are smaller. Since the smaller the vibration amplitude of the air guide plate 212, the smaller the degree of wind softening, and the smaller the frequency of the air guide plate 212, the smaller the degree of wind softening, the smaller the vibration amplitude and vibration frequency of the air guide plate 212, the smaller the degree of wind softening.

[0109] The greater the frequency of the driving signal, the greater the voltage peak value thereof. When the driving signal drives the resonant actuator to cause the air guide plate 212 to vibrate, the vibration amplitude and the vibration frequency of the air guide plate 212 are greater. Since the greater the vibration amplitude of the air guide plate 212, the greater the degree of wind softening, and the greater the frequency of the air guide plate 212, the greater the degree of wind softening, the greater the vibration amplitude and the vibration frequency of the air guide plate 212, the greater the degree of wind softening.

[0110] In this way, the degree of wind softening corresponding to a driving signal with relatively small frequency and voltage peak and a driving signal with relatively large frequency and voltage peak is more different, making the switching between strong and weak wind more obvious and the pulsation of the wind stronger.

[0111] In an exemplary embodiment, within a single cycle of the driving signal, the signal duration of each driving signal is 2 to 20 seconds, and preferably 3 to 5 seconds.

[0112] When a driving signal is continuously sent to the resonant actuator, the sending duration of the driving signal is the signal duration of the driving signal. The signal duration of each driving signal is equal to the duration of the driving signal driving the resonant actuator to drive the air guide plate 212 to vibrate.

[0113] The signal duration of each driving signal is set to be more than 2 seconds, and the duration of each driving signal driving the resonant actuator to drive the air guide plate 212 to vibrate is more than 2 seconds, and the user can clearly distinguish the different degrees of wind softening corresponding to two adjacent driving signals. The boundaries of wind softening degrees corresponding to different types of driving signals are clearer.

[0114] The signal duration of each driving signal is set to be less than 20 seconds. Then, each driving signal drives the resonant actuator to drive the air guide plate 212 to vibrate for less than 20 seconds. The wind output by the air treatment equipment will be maintained at the same softening degree for no longer than 20 seconds, and the user can clearly feel the fluctuation of the wind softening degree in a relatively short period of time.

[0115] In an exemplary embodiment, the signal duration of each driving signal is the same, for example, the signal duration of each driving signal may be 3 seconds.

[0116] The signal duration of the driving signal is the same, and the softening degree of the wind output by the air handling device can be switched evenly in the time dimension, forming a pulsating wind feeling with a more regular softening degree fluctuation.

[0117] In an exemplary embodiment, within a single cycle of the driving signal, the signal durations of at least two driving signals are different.

[0118] For example, the signal durations of the various driving signals are all different; or, the signal durations of a portion of the driving signals are different, and the signal durations of another portion of the driving signals are different.

[0119] The signal durations of the driving signals are different, and the softening degree of the wind output by the air handling equipment is switched unevenly in the time dimension, forming a pulsating wind feeling with irregular fluctuations in the softening degree.

[0120] In an illustrative embodiment, at least two of the multiple drive signals have different frequencies. The frequencies of each drive signal may be different. Among the multiple drive signals, the drive signal with a higher frequency has a longer signal duration.

[0121] The higher the frequency of the driving signal, the higher the frequency at which the driving signal drives the resonant actuator to vibrate the air guide plate 212, and the higher the softening degree of the airflow. Since the higher the frequency of the driving signal, the longer the signal duration, the higher the softening degree of the airflow, the longer the airflow maintains a high softening degree, and the better the user experience.

[0122] In some embodiments, the frequency of a portion of the multiple drive signals is equal to the first resonant frequency of the wind guide component 2, and the frequency of another portion of the multiple drive signals is equal to the second resonant frequency of the wind guide component 2. The first resonant frequency and the second resonant frequency have different orders.

[0123] When the frequency of the driving signal is equal to the first resonant frequency of the wind guide component 2, the signal duration is 7 to 15 seconds, and when the frequency of the driving signal is equal to the driving signal of the second resonant frequency, the signal duration is 3 to 5 seconds. The order of the first resonant frequency can be higher than the order of the second resonant frequency, for example, the first resonant frequency is the second order resonant frequency, and the second resonant frequency is the first order resonant frequency. By reasonably configuring the signal duration of resonant frequencies of different orders, a more comfortable wind feeling can be created and the windless effect can be improved.

[0124] In some embodiments, at least two of the multiple drive signals have different frequencies. The frequencies of each drive signal may be different. Among the multiple drive signals, the drive signal with a higher frequency has a shorter signal duration.

[0125] In some embodiments, at least two of the multiple drive signals have different frequencies. The frequencies of each drive signal may be different. Among the multiple drive signals, at least two drive signals with different frequencies have the same signal duration.

[0126] In an illustrative embodiment, the control method further includes a step S0 before the step S1 .

[0127] Step S0: The control device receives the user's settings on the number of drive signals, the arrangement order of the drive signals, the signal duration of each drive signal, the voltage peak value of each drive signal and / or the frequency of each drive signal.

[0128] The user can use the mobile terminal to set the number of drive signal types (including type and quantity), the order of all drive signals in a cycle, the voltage peak size of each drive signal, and the frequency size of each drive signal. The mobile terminal sends the user's settings to the control device of the air treatment equipment.

[0129] In step S2, the driving signal sent by the control device to the resonant actuator is the driving signal set by the user.

[0130] Users can pre-set multiple drive signals and freely create personalized pulsating wind to enhance user experience.

[0131] In some embodiments, the plurality of drive signals include a first drive signal and a second drive signal. The first drive signal and the second drive signal are sent alternately to the resonant actuator. The signal durations of the first drive signal and the second drive signal may be the same or different.

[0132] The voltage peak values ​​of the first drive signal and the second drive signal are different. For example, the voltage peak values ​​of the first drive signal and the second drive signal are both greater than zero, and the first drive signal is less than the second drive signal. For another example, the voltage peak value of the first drive signal is zero, and the voltage peak value of the second drive signal is greater than zero.

[0133] The frequencies of the first driving signal and the second driving signal are different. For example, the frequency of the first driving signal is equal to the first-order resonance frequency of the wind guide component 2 , and the frequency of the second driving signal is equal to the second-order resonance frequency of the wind guide component 2 .

[0134] In some embodiments, the plurality of driving signals include a first driving signal, a second driving signal, ... an Nth driving signal, where N is greater than or equal to 3.

[0135] In one cycle, the first drive signal, the second drive signal, ... the Nth drive signal are sequentially sent to the resonant actuator.

[0136] Among the voltage peak values ​​of the first drive signal, the second drive signal ... the Nth drive signal, the voltage peak values ​​of at least two drive signals are different, and / or, among the frequencies of the first drive signal, the second drive signal ... the Nth drive signal, the frequencies of at least two drive signals are different, and / or, among the signal durations of the first drive signal, the second drive signal ... the Nth drive signal, the signal durations of at least two drive signals are different.

[0137] The voltage peak values ​​of the first drive signal, the second drive signal ... the Nth drive signal may increase successively, the frequencies of the first drive signal, the second drive signal ... the Nth drive signal may increase successively, and the signal durations of the first drive signal, the second drive signal ... the Nth drive signal may increase successively.
