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, some researchers have conducted some research on the wind sensation adjustment and natural wind simulation characteristics of air conditioners, and have made some progress.

[0003] For example, a spoiler is installed inside the air outlet of the air conditioner. The wind feeling can be adjusted by the raised part on the surface of the spoiler and the rotation of the spoiler in the air duct. However, the above method of adding a spoiler causes serious attenuation of the air volume because the spoiler is installed inside the air outlet of the air conditioner; and a very reliable model is not proposed, making it difficult to achieve true natural wind simulation.

[0004] In particular, existing air conditioners are unable to create personalized wind sensations according to user needs. Summary of the invention

[0005] The technical problem to be solved by the present invention is that the air supply of the existing air handling equipment cannot create a personalized wind feeling.

[0006] 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:

[0007] Get non-periodic signals;

[0008] Sending a drive signal to the resonant actuator, wherein a trend of a voltage peak value and / or a frequency change over time of the drive signal is opposite to or the same as a trend of a frequency or an amplitude change over time of the non-periodic signal;

[0009] The frequency range of the driving signal is the resonant frequency range of the air guide component.

[0010] In an illustrative embodiment, the voltage peak value of the driving signal at a corresponding time point corresponds to the frequency of the non-periodic signal, and there is a positive correlation or a negative correlation between the voltage peak value of the driving signal and the frequency of the corresponding non-periodic signal.

[0011] In an illustrative embodiment, the voltage peak value of the driving signal at corresponding time points corresponds to the amplitude of the non-periodic signal, and there is a positive correlation or a negative correlation between the voltage peak value of the driving signal and the amplitude of the corresponding non-periodic signal.

[0012] In an illustrative embodiment, the value range of the frequency of the non-periodic signal is divided into a plurality of non-overlapping frequency ranges;

[0013] Different frequency ranges correspond to resonant frequencies of different orders of the air guide component;

[0014] A frequency range with a larger frequency corresponds to a higher order resonant frequency, or a frequency range with a smaller frequency corresponds to a higher order resonant frequency;

[0015] The frequency of the driving signal at the corresponding time point corresponds to the frequency of the non-periodic signal, and the frequency of the driving signal is equal to the resonant frequency of the wind guide component corresponding to the frequency range to which the frequency of the corresponding non-periodic signal belongs.

[0016] In an illustrative embodiment, the amplitude range of the non-periodic signal is divided into a plurality of non-overlapping amplitude ranges;

[0017] Different amplitude ranges correspond to resonant frequencies of different orders of the air guide component;

[0018] An amplitude range with a larger amplitude corresponds to a higher order resonant frequency, or an amplitude range with a smaller amplitude corresponds to a higher order resonant frequency;

[0019] The frequency of the driving signal at the corresponding time point corresponds to the amplitude of the non-periodic signal, and the frequency of the driving signal is equal to the resonant frequency of the wind guide component corresponding to the amplitude range to which the amplitude of the corresponding non-periodic signal belongs.

[0020] In an illustrative embodiment, the non-periodic signal is a baseband signal of a music signal;

[0021] The trend of the voltage peak value and / or frequency of the driving signal changing over time is opposite to or the same as the trend of the frequency of the baseband signal changing over time.

[0022] In an illustrative embodiment, it also includes:

[0023] When a driving signal is sent to the resonant actuator, the music signal is played synchronously.

[0024] In an illustrative embodiment, the non-periodic signal is a wind speed sample signal of natural wind;

[0025] The trend of the voltage peak value and / or frequency of the driving signal changing over time is opposite to or the same as the trend of the amplitude of the wind speed sample signal changing over time.

[0026] In an illustrative embodiment, the acquiring of the non-periodic signal includes:

[0027] Receive instructions from designated areas;

[0028] Download the natural wind speed sample signal of the area specified by the designated area instruction from the information network. The present application also proposes a computer readable storage medium on which a computer program is stored. When the computer program is executed by a processor, the control method of the air treatment device as described above is implemented.

[0029] The present application also proposes an air treatment device, which comprises:

[0030] The housing is provided with an air supply channel and an air outlet arranged at one end of the air supply channel;

[0031] 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

[0032] The control device is electrically connected to the resonant actuator and is configured to execute the control method of the air treatment equipment as described above.

[0033] In an embodiment of the present application, when the voltage peak and / or frequency of the driving signal changes non-periodically following the frequency or amplitude of the non-periodic signal, the degree of turbulence of the air flow output from the air outlet by the air guide vane changes non-periodically, and the degree of softening of the air flow at the air outlet changes non-periodically, thereby simulating wind with irregularly changing wind sensation.

[0034] Since the trend of the voltage peak and / or frequency of the driving signal changing over time can determine the change in the softness of the wind, and the non-periodic signal determines the trend of the voltage peak and / or frequency of the driving signal changing over time, different non-periodic signals can be input to control the change in the softness of the wind, thereby creating a personalized and differentiated wind feeling.

[0035] The air guide pieces of the air guide component redistribute the wind field at the air outlet by resonance to create a wind with an irregularly changing wind feeling. 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 equipment.

[0049] 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.

[0050] 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.

[0051] 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.

[0052] 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.

[0053] 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.

[0054] 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 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.

[0055] 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.

[0056] 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.

[0057] like Figure 3 As 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.

[0058] 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.

[0059] 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.

[0060] Simply put, 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 plate 212 is called resonance. The amplitude of the air guide plate 212 will increase sharply, so that the air guide plate 212 can more effectively disturb the air flow and improve the wind feel of the air outlet.

[0061] 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 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.

[0062] 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.

[0063] The piezoelectric material piece may be a piezoelectric actuator or a piezoelectric sheet. The piezoelectric material piece may be, for example, a piezoelectric ceramic. An alternating voltage is applied to the polarization direction of the piezoelectric material piece, and the inverse piezoelectric effect of the piezoelectric material piece is utilized to cause the piezoelectric material piece to deform back and forth, thereby driving the air guide piece 212 to resonate and achieve the purpose of turbulence. The piezoelectric sheet is a sheet-like body formed of 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.

[0064] 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.

[0065] 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.

[0066] For example, the resonant actuator includes an electrostrictive actuator, which drives the air guide piece 212 to resonate through the electrostrictive effect.

[0067] 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.

[0068] 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.

[0069] For example, the resonant actuator includes a magnetostrictive actuator, which drives the air guide plate 212 to resonate through the magnetostrictive effect.

[0070] 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.

[0071] 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.

[0072] 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.

[0073] 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.

[0074] For example, the resonant actuator includes an electrorheological fluid actuator, which drives the air guide blade 212 to resonate by deforming the electrorheological fluid.

[0075] 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.

[0076] 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.

[0077] 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 11, 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.

[0078] 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.

[0079] 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.

[0080] 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.

[0081] The resonant actuator is a piezoelectric material. When an alternating voltage 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.

[0082] 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 pulse signal, and the voltage pulse signal can be an AC voltage signal.

[0083] The control device controls the vibration amplitude of the air guide plate 212 by controlling the voltage amplitude of the driving signal. When the air outlet speed of the air outlet 11 of the air handling device is the same, the greater the absolute value of the voltage 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.

[0084] 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 voltage pulse 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.

[0085] 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.

[0086] 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:

[0087] Step S1: The control device receives a wind sense adjustment instruction and proceeds to step S2;

[0088] The air supply component is in operation so that the air outlet 11 of the air handling device supplies air outward. The air volume of the air outlet 11 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 11. The user can select one of the air volume gears to set the air volume of the air outlet 11.

[0089] 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 wind sense of the airflow output by the air outlet 11 of the air handling device.

[0090] Step S2: the control device obtains a non-periodic signal;

[0091] A non-periodic signal is a signal whose amplitude and / or frequency changes non-periodically over time. A non-periodic signal can be a signal that fluctuates continuously in time, and the amplitude and frequency of the non-periodic signal do not change periodically over time. The frequency of the non-periodic signal changes over time. The non-periodic signal can be an audio signal or a wind speed sample signal of natural wind. The non-periodic signal can be pre-stored in a storage unit of the control device. Only one non-periodic signal can be stored in the storage unit, and the control device can read the non-periodic signal in the storage unit. Multiple non-periodic signals can also be stored in the storage unit, and the multiple non-periodic signals are different from each other. The control device can read one of the multiple non-periodic signals in the storage unit according to user instructions. The non-periodic signal can also be collected in real time.

[0092] Step S3: The control device sends a drive signal to the resonant actuator, and the trend of the voltage peak and / or frequency of the drive signal changing over time is opposite to or the same as the trend of the frequency or amplitude of the non-periodic signal changing over time. The frequency range of the drive signal is the resonant frequency range of the air guide component 2.

[0093] 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 undergoes reciprocating deformation when receiving the driving signal, and drives the air guide plate 212 to vibrate through the reciprocating deformation of the resonant actuator itself.

[0094] 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 plate 212 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 second-order resonant frequency are both within 100 Hz. 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, and is 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 component 2 resonates.

[0095] The control device determines the trend of the voltage peak and / or frequency of the drive signal over time according to the trend of the frequency or amplitude of the non-periodic signal over time. The trend of the voltage peak and / or frequency of the drive signal over time is opposite to the trend of the frequency or amplitude of the non-periodic signal over time, or the trend of the voltage peak and / or frequency of the drive signal over time is the same as the trend of the frequency or amplitude of the non-periodic signal over time. In this way, the control device is equivalent to converting the non-periodic signal into a drive signal, and the control device sends the drive signal to the resonant actuator to drive the air guide 212 to vibrate.

[0096] 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 212. When the trend of the voltage peak value of the driving signal changing with time is non-periodic, the degree of disturbance of the airflow output from the air outlet 11 by the air guide 212 is non-periodic, that is, the resonance of the air guide 212 causes the wind speed and turbulence of the airflow to change non-periodically, and therefore, the softening degree of the airflow at the air outlet 11 is non-periodic, thereby simulating wind with irregularly changing wind feeling. In some examples, the driving signal may also change with the non-periodic signal collected in real time, and the driving signal may be delayed within a reasonable range relative to the non-periodic signal, for example, slightly delayed, so that the air guide 212 swings with the wind or music.

[0097] 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 non-periodically over time, the degree of disturbance of the airflow output from the air outlet 11 by the air guide plate 212 changes non-periodically, that is, the resonance of the air guide component 2 causes the wind speed and turbulence of the airflow to change non-periodically, and therefore, the softening degree of the airflow at the air outlet 11 changes non-periodically, thereby simulating wind with irregularly changing wind sensations.

[0098] Similarly, when the voltage peak and frequency of the driving signal change non-periodically synchronously, the degree of disturbance of the airflow output from the air outlet 11 by the air guide plate 212 changes non-periodically, and the degree of softening of the airflow at the air outlet 11 changes non-periodically, thereby simulating wind with irregularly changing wind sensation.

[0099] Since the trend of the voltage peak and / or frequency of the driving signal changing over time can determine the change in the softness of the wind, and the non-periodic signal determines the trend of the voltage peak and / or frequency of the driving signal changing over time, different non-periodic signals can be input to control the change in the softness of the wind, thereby creating a personalized and differentiated wind feeling.

[0100] The air guide pieces 212 of the air guide component 2 redistribute the wind field at the air outlet 11 by resonance to create a wind with an irregularly changing wind feeling. The air guide component 2 has very little resistance to the airflow output from the air outlet 11 and will not affect the air volume of the air outlet 11 of the air treatment equipment.

[0101] In an illustrative embodiment, the voltage peak of the driving signal at the corresponding time point corresponds to the frequency of the non-periodic signal, and the voltage peak of the driving signal may be positively correlated or negatively correlated with the frequency of the non-periodic signal corresponding to it. The corresponding time point may be the same time point on the driving signal and the non-periodic signal, or the time point of the driving signal corresponds to the time point of the non-periodic signal delay preset duration. The corresponding time point of the driving signal may be the same time point as the non-periodic signal or a time point that is delayed within a reasonable range relative to the non-periodic signal, such as a slightly delayed time point, and the time point of the non-periodic signal may be a time point when the signal is collected in real time or a time point when the stored non-periodic signal is read. For example, the voltage peak of the driving signal is equal to the frequency of the non-periodic signal corresponding to it multiplied by a first preset coefficient. If the first preset coefficient is a negative number, the trend of the voltage peak of the driving signal changing over time is opposite to the trend of the frequency of the non-periodic signal changing over time. If the first preset coefficient is a positive number, the trend of the voltage peak of the driving signal changing over time is the same as the trend of the frequency of the non-periodic signal changing over time. In this way, when the frequency of the non-periodic signal increases over time, the voltage peak of the driving signal also increases over time, and the softening degree of the wind output by the air handling equipment increases; when the frequency of the non-periodic signal decreases over time, the voltage peak of the driving signal also decreases over time, and the softening degree of the wind output by the air handling equipment decreases.

[0102] In an illustrative embodiment, the voltage peak of the driving signal at the corresponding time point corresponds to the amplitude of the non-periodic signal, and the voltage peak of the driving signal may be positively correlated or negatively correlated with the amplitude of the corresponding non-periodic signal. For example, the voltage peak of the driving signal is equal to the amplitude of the corresponding non-periodic signal multiplied by the second preset coefficient. If the second preset coefficient is a negative number, the trend of the voltage peak of the driving signal changing over time is opposite to the trend of the amplitude of the non-periodic signal changing over time. If the second preset coefficient is a positive number, the trend of the voltage peak of the driving signal changing over time is the same as the trend of the amplitude of the non-periodic signal changing over time. In this way, when the frequency of the non-periodic signal decreases over time, the voltage peak of the driving signal increases over time, and the softening degree of the wind output by the air treatment device increases; when the frequency of the non-periodic signal increases over time, the voltage peak of the driving signal decreases over time, and the softening degree of the wind output by the air treatment device decreases.

[0103] In an illustrative embodiment, the value range of the frequency of the non-periodic signal is divided into a plurality of non-overlapping frequency ranges, each of which is a continuous interval. Different frequency ranges correspond to resonant frequencies of different orders of the air guide component 2, and a frequency range with a larger frequency corresponds to a resonant frequency of a higher order. The frequency of the drive signal at the corresponding time point corresponds to the frequency of the non-periodic signal, and the frequency of the drive signal is equal to the resonant frequency of the air guide component 2 corresponding to the frequency range to which the frequency of the corresponding non-periodic signal belongs.

[0104] For example, the frequency values ​​in the first frequency range, the second frequency range, and the third frequency range increase successively. The first frequency range corresponds to the first-order resonant frequency of the wind guide component 2, the second frequency range corresponds to the second-order resonant frequency of the wind guide component 2, and the third frequency range corresponds to the third-order resonant frequency of the wind guide component 2. If the frequency of the non-periodic signal belongs to the first frequency range, the frequency of the driving signal at the corresponding time point is equal to the first-order resonant frequency of the wind guide component 2. If the frequency of the non-periodic signal belongs to the second frequency range, the frequency of the driving signal at the same time point is equal to the second-order resonant frequency of the wind guide component 2. If the frequency of the non-periodic signal belongs to the third frequency range, the frequency of the driving signal at the corresponding time point is equal to the third-order resonant frequency of the wind guide component 2.

[0105] In this way, when the frequency of the non-periodic signal decreases over time, the frequency of the driving signal decreases over time, and the softening degree of the wind output by the air handling equipment decreases; when the frequency of the non-periodic signal increases over time, the frequency of the driving signal increases over time, and the softening degree of the wind output by the air handling equipment increases.

[0106] In an illustrative embodiment, the value range of the frequency of the non-periodic signal is divided into a plurality of non-overlapping frequency ranges, each of which is a continuous interval. Different frequency ranges correspond to resonant frequencies of different orders of the air guide component 2, and the frequency range with a smaller frequency corresponds to a resonant frequency with a higher order. The frequency of the drive signal at the corresponding time point corresponds to the frequency of the non-periodic signal, and the frequency of the drive signal is equal to the resonant frequency of the air guide component 2 corresponding to the frequency range to which the frequency of the corresponding non-periodic signal belongs.

[0107] In this way, when the frequency of the non-periodic signal decreases over time, the frequency of the driving signal increases over time, and the softening degree of the wind output by the air handling equipment increases; when the frequency of the non-periodic signal increases over time, the frequency of the driving signal decreases over time, and the softening degree of the wind output by the air handling equipment decreases.

[0108] In an illustrative embodiment, the range of the amplitude of the non-periodic signal is divided into a plurality of non-overlapping amplitude ranges, each of which is a continuous interval. Different amplitude ranges correspond to resonant frequencies of different orders of the air guide component 2, and an amplitude range with a larger amplitude corresponds to a resonant frequency of a higher order. The frequency of the drive signal at the corresponding time point corresponds to the amplitude of the non-periodic signal, and the frequency of the drive signal is equal to the resonant frequency of the air guide component 2 corresponding to the amplitude range to which the amplitude of the corresponding non-periodic signal belongs.

[0109] For example, the frequency values ​​in the first amplitude range, the second amplitude range, and the third amplitude range increase successively. The first amplitude range corresponds to the first-order resonant frequency of the wind guide component 2, the second amplitude range corresponds to the second-order resonant frequency of the wind guide component 2, and the third amplitude range corresponds to the third-order resonant frequency of the wind guide component 2. If the amplitude of the non-periodic signal belongs to the first amplitude range, the frequency of the drive signal at the corresponding time point is equal to the first-order resonant frequency of the wind guide component 2. If the amplitude of the non-periodic signal belongs to the second amplitude range, the frequency of the drive signal at the corresponding time point is equal to the second-order resonant frequency of the wind guide component 2. If the amplitude of the non-periodic signal belongs to the third amplitude range, the frequency of the drive signal at the corresponding time point is equal to the third-order resonant frequency of the wind guide component 2.

[0110] In this way, when the amplitude of the non-periodic signal decreases over time, the frequency of the driving signal decreases over time, and the softening degree of the wind output by the air handling equipment decreases; when the amplitude of the non-periodic signal increases over time, the frequency of the driving signal increases over time, and the softening degree of the wind output by the air handling equipment increases.

[0111] In an illustrative embodiment, the range of the amplitude of the non-periodic signal is divided into a plurality of non-overlapping amplitude ranges, each of which is a continuous interval. Different amplitude ranges correspond to resonant frequencies of different orders of the air guide component 2, and the smaller the amplitude range, the higher the order of the resonant frequency. The frequency of the drive signal at the corresponding time point corresponds to the amplitude of the non-periodic signal, and the frequency of the drive signal is equal to the resonant frequency of the air guide component 2 corresponding to the amplitude range to which the amplitude of the corresponding non-periodic signal belongs.

[0112] In this way, when the amplitude of the non-periodic signal decreases over time, the frequency of the driving signal increases over time, and the softening degree of the wind output by the air handling equipment increases; when the amplitude of the non-periodic signal increases over time, the frequency of the driving signal decreases over time, and the softening degree of the wind output by the air handling equipment decreases.

[0113] In an illustrative embodiment, the non-periodic signal is a baseband signal of a music signal. Step S2 includes: the control device extracts the baseband signal from the music signal and uses the baseband signal as the non-periodic signal.

[0114] In step S3, the control device sends a drive signal to the resonant actuator, wherein the voltage peak value and / or the time-varying trend of the frequency of the drive signal is opposite to or the same as the time-varying trend of the frequency of the baseband signal.

[0115] The fundamental frequency is a harmonic component of a composite vibration or waveform (such as a sound wave). The fundamental frequency usually has the lowest frequency and the largest amplitude. The algorithm for extracting the fundamental frequency signal from the music signal can adopt the YIN algorithm, the SWIPE algorithm, the CREPE algorithm or the SPICE algorithm. The fundamental frequency can be used to determine the mode and melody of the music. When the fundamental frequency signal of the music is used as a non-periodic signal and the trend of the voltage peak and / or frequency change of the driving signal over time is determined by the frequency of the fundamental frequency signal of the music, the trend of the voltage peak and / or frequency change of the driving signal over time is consistent with the change of the melody of the music, so that the softening degree of the airflow output from the air outlet 11 can change according to the melody of the music, and the change of the airflow output from the air outlet 11 is more coordinated. At the same time, a variety of music can be stored in the storage unit of the control device in advance, and the user can select different music as needed to obtain different wind sensations.

[0116] In an illustrative embodiment, the air treatment device further comprises a speaker. The speaker is electrically connected to the control device. The control device is provided with an audio decoder, which can decode the music file into a music signal and send it to the speaker for playing.

[0117] Step S3 also includes that when the control device sends a driving signal to the resonant actuator, it simultaneously sends a music signal to the speaker to drive the speaker to play music, and the trend of the voltage peak and / or frequency change of the driving signal over time is consistent with the frequency of the fundamental frequency signal of the music signal.

[0118] The air handling device can simultaneously adjust the softening degree of the airflow output from the air outlet 11 according to the melody of the music while playing the music, thereby improving the user experience.

[0119] In an exemplary embodiment, the non-periodic signal is a wind speed sample signal of natural wind.

[0120] In step S3, the control device sends a driving signal to the resonant actuator, and the trend of the voltage peak value and / or frequency of the driving signal changing over time is opposite to the trend of the amplitude of the wind speed sample signal changing over time.

[0121] The wind speed sample signal of the natural wind can be a curve showing the relationship between the wind speed of the natural wind and time. The amplitude of the wind speed sample signal can represent the wind speed value of the natural wind. The wind speed sample signal of the natural wind can be collected by an anemometer. The wind speed sample signal of the natural wind can be pre-stored in a storage unit of the control device.

[0122] When the wind speed sample signal of the natural wind is used as a non-periodic signal and the amplitude of the wind speed sample signal of the natural wind is used to determine the trend of the voltage peak value and / or frequency of the driving signal changing over time, the trend of the voltage peak value and / or frequency of the driving signal changing over time is opposite to the trend of the amplitude change of the wind speed sample signal. When the amplitude of the wind speed sample signal of the natural wind increases, it means that the wind speed value of the natural wind increases. At this time, the voltage peak value and / or frequency of the driving signal are reduced according to the increase in the amplitude of the natural wind, which can reduce the softening degree of the airflow output from the air outlet 11, so that the user can feel the increase in the airflow speed output from the air outlet 11; on the contrary, when the amplitude of the wind speed sample signal of the natural wind decreases, it means that the wind speed value of the natural wind decreases. At this time, the voltage peak value and / or frequency of the driving signal are increased according to the decrease in the amplitude of the natural wind, which can increase the softening degree of the airflow output from the air outlet 11, so that the user can feel that the airflow speed output from the air outlet 11 decreases and the airflow becomes softer. Thus, the air handling device can simulate the wind with a natural wind feeling according to the wind speed sample signal of the natural wind. At the same time, a plurality of wind speed sample signals of the natural wind can be stored in the storage unit of the control device in advance, and the user can select different wind speed sample signals of the natural wind as needed to obtain wind with different natural wind feelings.

[0123] In an illustrative embodiment, the air treatment device further comprises a communication module. The communication module is electrically connected to the control device. The communication module can be a wireless communication module or a wired communication module. The communication module can be connected to an information network, which can be a local area network or a world wide web.

[0124] The air handling device can be connected to the information network through the communication module to obtain the non-periodic signal from the information network in real time. For example, the control device obtains a music signal from the information network in real time through the communication module, and the music signal is, for example, a music broadcast, and determines the voltage peak value and / or frequency change trend of the driving signal over time according to the frequency change trend of the baseband signal of the music signal over time.

[0125] For example, multiple anemometers are set up in different areas, and the anemometers collect wind speed sample signals of natural wind in the area where they are located, and the anemometers upload the collected real-time wind speed sample signals to the information network. The user can send a designated area instruction to the air handling device to specify the wind feeling of the natural wind in a designated area.

[0126] In step S2, after receiving the designated area instruction, the control device can download the wind speed sample signal of the natural wind collected by the anemometer in the area from the information network according to the area specified by the designated area instruction, and determine the trend of the voltage peak and / or frequency change over time of the driving signal according to the amplitude change trend of the wind speed sample signal over time. Driving the resonant actuator with the driving signal can make the wind feeling of the airflow output by the air treatment equipment consistent with the wind feeling of the natural wind in the designated area.
