[0029] To make the objectives, technical solutions and advantages of the present application clearer, the technical solutions of the present application will be described below in connection with specific embodiments of the present application and corresponding drawings. Obviously, the described embodiments are only some of the embodiments of the present application, but not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without any creative effort fall within the scope of protection of the present application.

[0030] It should be noted that the terms "first", "second" and the like in the specification and claims of the present application and the above-described drawings are used to distinguish similar objects, and do not necessarily indicate a specific order or a chronological sequence. It should be understood that the data thus used can be interchanged under appropriate circumstances, so that the embodiments of the present application described herein can be implemented in an order other than that illustrated or described herein. In addition, the terms "include" and "have" and any variations thereof are intended to cover non-exclusive inclusion, for example, a process, method, system, product or device that includes a series of steps or units does not necessarily have to be limited to those steps or units clearly listed, but can include other steps or units not clearly listed or inherent to the process, method, product or device.

[0031] The existing methods for suppressing structural resonance mainly include the following two methods: one is to change the frequency characteristics of the excitation source so as to be offset from the structural modal frequency; the other is to use high-damping materials or additional damping to reduce the resonance amplitude. The first method of changing the excitation source is often limited by the operation of the machine equipment, and the potential for adjustment in the actual process is limited; the second method can only reduce the sound radiation intensity of the plate structure to a certain extent.

[0032] The application provides a control method of an air conditioner. A panel of the air conditioner is made of a composite alloy panel. The composite alloy panel can be a shape memory alloy (SMA) gradient composite panel. The SMA is a kind of smart material, which has the characteristics of temperature control and magnetic control. The upper and lower surface panels of the composite sandwich panel are respectively orthogonally embedded with SMA fiber filaments containing tensile pre-strain, and the core layer is an isotropic gradient functional structure composed of graphite and epoxy resin. With the increase of temperature, the SMA transforms from martensite phase to austenite phase, which leads to the increase of the elastic modulus and recovery stress of the SMA. When the volume fraction and SMA pre-strain of the SMA fiber on the surface layer of the composite sandwich panel increase, the natural frequency of the composite sandwich panel increases.

[0033] Figure 1 The application provides a method schematic diagram of an embodiment of the control method of the air conditioner.

[0034] As shown in Figure 1 According to one embodiment of the application, the control method of the air conditioner at least includes steps S110, S120 and S130.

[0035] In step S110, a pre-established corresponding relationship between the operating frequency of the air conditioner and the panel temperature is obtained.

[0036] The corresponding relationship can specifically include the panel temperature corresponding to the optimal sound quality of the air conditioner when the air conditioner operates at different frequencies.

[0037] In one specific embodiment, the sound quality of the panel at different panel temperatures when the air conditioner operates at different frequencies can be obtained by pre-experimental testing, and the panel temperature corresponding to the optimal sound quality of the air conditioner when the air conditioner operates at different frequencies is obtained.

[0038] Figure 2 A step schematic diagram of one specific embodiment of pre-establishing the corresponding relationship between the operating frequency of the air conditioner and the panel temperature according to the application is shown.

[0039] As shown in Figure 2 In one specific embodiment, the corresponding relationship between the operating frequency of the air conditioner and the panel temperature is pre-established by the following steps S1-S3.

[0040] In step S1, a sound quality model of the panel of the air conditioner is constructed, and the sound quality parameter values corresponding to different parameter values of k material parameters of the panel when the air conditioner operates at different frequencies are obtained.

[0041] Specifically, the panel of the air conditioner can include one or more sound quality parameters. A sound quality parameter model can be constructed for each sound quality parameter. The sound quality model can include one or more sound quality parameter models. In a specific embodiment, the sound quality parameters include at least one of loudness F N , sharpness F S , roughness F R . Thus, the sound quality model of the panel can include a loudness model, a sharpness model, a roughness model, for example, a loudness model F N , a sharpness model F S , a roughness model F R may be as follows, respectively:

[0042]

[0043] The k material parameters of the panel are factors affecting the sound quality model, that is, the sound quality model includes k material parameter factors x1, x2, …, x k . That is, the parameter values of the k material parameters x1, x2, …, x k are different, and the corresponding sound quality parameters are also different. The different parameter values of the k material parameters of the panel corresponding to the sound quality parameter values when the air conditioner is running at different frequencies can be obtained by experimental testing. That is, when the air conditioner is running at different frequencies, the parameter values of the k material parameters are different, and the corresponding sound quality parameter values are different. The above loudness model F N , sharpness model F S , roughness model F R may be loudness F N , sharpness F S , roughness F R . The linear expression of the k material parameters can be obtained by linear fitting.

[0044] Step S2, obtaining the sound power and mode of the panel at different panel temperatures when the air conditioner is running at different frequencies, and the parameter values of the k material parameters of the panel at different panel temperatures, which are obtained by experimental testing in advance.

[0045] Specifically, the sound power and mode of the panel at different panel temperatures when the air conditioner is running at different frequencies, and the parameter values of the k material parameters of the panel at different panel temperatures when the air conditioner is running at different frequencies are obtained by experimental testing in advance. For example, the sound power and mode of the panel at different panel temperatures when the air conditioner is running at different frequencies can be obtained by simulation testing.

[0046] Step S3, based on the constructed sound quality model, the obtained sound quality parameter values corresponding to different parameter values of the k material parameters of the panel at different panel temperatures when the air conditioner is running at different frequencies, the sound power and mode of the panel at different panel temperatures when the air conditioner is running at different frequencies, and the parameter values of the k material parameters, a corresponding relationship between the running frequency of the air conditioner and the panel temperature is established.

[0047] Figure 3 A step flow chart of one specific embodiment of establishing the corresponding relationship between the running frequency of the air conditioner and the panel temperature according to the present application is shown. As shown in Figure 3 , in one specific embodiment, establishing the corresponding relationship between the running frequency of the air conditioner and the panel temperature includes the following steps S31-S33:

[0048] Step S31, according to the sound power and mode of the panel at different panel temperatures when the air conditioner is running at different frequencies, and the values of the k material parameters of the panel at different panel temperatures, the relationship between the panel temperature of the panel and the k material parameters of the air conditioner running at different frequencies is obtained by fitting through a first preset algorithm.

[0049] For example, according to the sound power and mode of the panel at different panel temperatures when the air conditioner is running at different frequencies, the panel temperature at which the sound quality is optimal and the values of the k material parameters are determined (the mode is the inherent property of the panel material, the mode changes, and the sound quality changes accordingly, so by testing the sound power and mode of the panel at different panel temperatures when the air conditioner is running at different frequencies, the panel temperature at which the sound quality is optimal and the values of the k material parameters of the air conditioner running at different frequencies can be determined from the sound power and mode), the relationship between the panel temperature y at which the sound quality is optimal and the k material parameters x1-xk of the panel when the air conditioner is running at different frequencies is obtained by linear fitting, and the relationship is a linear relationship: y = a + bx, where x takes the values of the parameter values of the k material parameters x1-xk, and y takes the values of y1-yk. The first preset algorithm may, for example, be linear interpolation.

[0050] Step S32, according to the sound quality model and the sound quality parameter values corresponding to different parameter values of the k material parameters of the panel at different panel temperatures when the air conditioner is running at different frequencies, the relationship between the panel temperature of the panel and the sound quality parameter of the air conditioner when the air conditioner is running at different frequencies is obtained by fitting through a second preset algorithm.

[0051] For example, the relationship between the panel temperature y of the panel and the sound quality F of the air conditioner when the air conditioner is running at different frequencies is obtained by linear fitting, and the relationship is a linear relationship: F = c + dy, where y takes the values of y1-yk, and F takes the values of loudness FN , sharpness F S , roughness F R ; the second preset algorithm can be least square method.

[0052] The values of a, b, c, and d in the above formula are k, and x1-xk are substituted into the initial values.

[0053] In step S33, the corresponding relationship between the operating frequency of the air conditioner and the panel temperature is iterated according to the obtained relationship between the panel temperature and the k material parameters when the air conditioner operates at different frequencies, and the relationship between the panel temperature and the sound quality parameters of the air conditioner.

[0054] Specifically, the panel temperature will affect the parameter values of the k material parameters x1, x2, …, x k By assigning an initial temperature, there will be initial parameter values X (including initial parameter values of x1-xk), which affect the inherent characteristics of the panel. When the panel temperature changes, the material parameters change, and the inherent characteristics of the panel (i.e. the modal of the panel) change. When the air conditioner operates at different frequencies, the modal of the panel changes, and the corresponding sound quality changes. According to the experimental test data, the relationship between the panel temperature and the k material parameters x1, x2, …, x k The relationship between the panel temperature and the sound quality (loudness, sharpness, and roughness) is fitted into the initial values. According to the two relationship formulas, the better temperature value and sound quality result of the air conditioner operating at different frequencies can be iterated, that is, the panel temperature corresponding to the optimal sound quality of the air conditioner operating at different frequencies.

[0055] Figure 4 A schematic diagram of a sound quality evaluation system according to the present application is shown. As Figure 4 The sound quality system includes a loudness model, a sharpness model, and a roughness model. By assigning initial values to the k material parameters, the sound power and modal of the panel corresponding to different parameter values of the k material parameters of the air conditioner operating at different frequencies are obtained by inputting the simulation software for modal analysis and acoustic analysis.

[0056] In step S120, the panel temperature corresponding to the current operating frequency of the air conditioner is obtained as the target panel temperature according to the obtained corresponding relationship.

[0057] Specifically, according to the corresponding relationship between the operating frequency of the air conditioner and the panel temperature, and the current operating frequency of the air conditioner, the panel temperature corresponding to the optimal sound quality of the air conditioner at the current operating frequency can be obtained, and the panel temperature is taken as the current target panel temperature.

[0058] Step S130, controlling the temperature of the panel by controlling the temperature control device on the panel, so that the panel reaches the target panel temperature.

[0059] Specifically, the temperature control device is controlled according to the current panel temperature and the target temperature, so that the panel reaches the target panel temperature. The temperature control device includes a heating device and a cooling device, and the panel temperature can be controlled by controlling the heating device and the cooling device. A temperature sensor is also arranged on the panel to detect the panel temperature, and the heating device is controlled to heat the panel or the cooling device is controlled to cool the panel according to the panel temperature detected by the temperature sensor. By controlling the panel temperature, the natural frequency, sound power, loudness, sharpness and roughness of the panel at each frequency point can be controlled, so as to improve the sound quality of the air conditioner from the perspective of reducing noise from the panel.

[0060] Figure 5 is a method schematic diagram of another embodiment of the control method of the air conditioner provided by the application. As shown in Figure 5 According to one embodiment of the application, the control method of the air conditioner further includes steps S140 and S150.

[0061] Step S140, receiving an opening instruction for opening an augmented reality mode, and opening the augmented reality mode of the air conditioner when the opening instruction is received.

[0062] Step S150, displaying the current sound quality parameters of the air conditioner, the current internal operation condition of the air conditioner and the internal dirt condition of the air conditioner in an augmented reality mode.

[0063] Specifically, by collecting user gesture images, a gesture opening instruction for opening an augmented reality mode is recognized, or a voice opening instruction for opening an augmented reality mode is received, and the augmented reality (AR) mode is opened. After entering the AR mode, the parameter values of the current sound quality parameters of the air conditioner, the current internal operation condition of the air conditioner and the internal dirt condition of the air conditioner are displayed by AR. The internal dirt condition of the air conditioner includes the distribution of bacteria and / or dust inside the air conditioner. For example, the inside of the air conditioner can be photographed by a camera inside the air conditioner, the image is displayed on the display screen, and the names of the internal components of the air conditioner, the number and / or distribution position of bacteria, and / or the distribution position and / or coverage area of dust are displayed on the displayed image by AR.

[0064] For the display screen of the existing air conditioner, gestures or voice control can be used to open the AR mode, and the screen will display the actual operation condition inside the air conditioner by AR, and display the dirt condition such as bacteria and dust inside the air conditioner in numerical form, and the comfort parameters corresponding to the sound quality can also be displayed.

[0065] Optionally, it can also include: reminding the user to use the self-cleaning function before the air conditioner is used, then reminding the user to start the self-cleaning function every preset time (for example, every month), and reminding the user to disassemble and clean when the internal dirt level threshold of the air conditioner reaches the preset threshold. For example, when the area covered by bacteria and / or dust on the internal area of the air conditioner reaches 30%, the user is reminded to do simple disassembly and cleaning work; when the area covered by bacteria and / or dust on the internal area of the air conditioner reaches 60%, the user is reminded that professional personnel need to come to the door for disassembly and cleaning services.

[0066] Optionally, it can also include: when the environmental TVOC concentration and / or carbon dioxide concentration reaches the corresponding preset threshold, reminding the user to start the fresh air function or open the window for ventilation.

[0067] The application also provides a control device of an air conditioner. The panel of the air conditioner adopts a composite alloy plate. The composite alloy plate can be a shape memory alloy (SMA) gradient composite plate. SMA is a kind of smart material, which has the characteristics of temperature control and magnetic control. The upper and lower surface plates of the composite sandwich plate are respectively orthogonally embedded with SMA fiber filaments containing tensile pre-strain, and the core layer is an isotropic gradient functional structure composed of graphite and epoxy resin. With the increase of temperature, SMA transforms from martensite phase to austenite phase, resulting in the increase of the elastic modulus and recovery stress of SMA. When the volume fraction and SMA pre-strain of the SMA fiber on the surface layer of the composite sandwich plate increase, the natural frequency of the composite sandwich plate increases.

[0068] Figure 6 is the structure block diagram of an embodiment of the control device of the air conditioner provided by the application. As shown in Figure 6 The control device 100 includes a first acquisition unit 110, a second acquisition unit 120, and a control unit 130.

[0069] The first acquisition unit 110 is configured to acquire a pre-established corresponding relationship between the operating frequency of the air conditioner and the panel temperature.

[0070] The corresponding relationship includes the panel temperature corresponding to the optimal sound quality of the air conditioner when the air conditioner operates at different frequencies.

[0071] In a specific embodiment, the sound quality of the panel at different panel temperatures when the air conditioner operates at different frequencies can be obtained by pre-experimental testing, and the panel temperature corresponding to the optimal sound quality of the air conditioner when the air conditioner operates at different frequencies is obtained.

[0072] The control device further includes an establishment unit (not shown) configured to pre-establish the corresponding relationship between the operating frequency of the air conditioner and the panel temperature.

[0073] Figure 2 A step diagram of one embodiment of pre-establishing the correspondence between the operating frequency of the air conditioner and the panel temperature according to the present application is shown. As shown in one embodiment, the establishing unit pre-establishes the correspondence between the operating frequency of the air conditioner and the panel temperature by the following steps S1-S1: Figure 2

[0074] Step S1, constructing the sound quality model of the panel of the air conditioner, and obtaining the sound quality parameter values corresponding to the different parameter values of the k material parameters of the panel when the air conditioner operates at different frequencies.

[0075] Specifically, the panel of the air conditioner can include more than one sound quality parameter. A corresponding sound quality parameter model can be constructed for each sound quality parameter. The sound quality model can include more than one sound quality parameter model. In one embodiment, the sound quality parameter includes at least one of loudness F N , sharpness F S , roughness F R . Therefore, the sound quality model of the panel can include a loudness model, a sharpness model, a roughness model, for example, a loudness model F N , a sharpness model F S , a roughness model F R may be as follows, respectively:

[0076]

[0077] The k material parameters of the panel are the influencing factors of the sound quality model, that is, the sound quality model includes k material parameter influencing factors x1, x2, …, x k . That is, the parameter values of the k material parameters x1, x2, …, x k are different, and the corresponding sound quality parameters are also different. The sound quality parameter values corresponding to the different parameter values of the k material parameters of the panel when the air conditioner operates at different frequencies can be obtained by experimental testing. That is, when the air conditioner operates at different frequencies, the parameter values of the k material parameters are different, and the corresponding sound quality parameter values are different. The above loudness model F N , sharpness model F S , roughness model F R may be loudness F N , sharpness F S , roughness F R . The linear expression of the k material parameters can be obtained by linear fitting.

[0078] ​Step S2, obtaining the sound power and mode of the panel at different panel temperatures when the air conditioner is running at different frequencies and the parameter values of the k material parameters of the panel at different panel temperatures obtained by experimental test in advance.

[0079] Specifically, the sound power and mode of the panel at different panel temperatures when the air conditioner is running at different frequencies and the parameter values of the k material parameters of the panel at different panel temperatures when the air conditioner is running at different frequencies are obtained by experimental test in advance. For example, the sound power and mode of the panel at different panel temperatures when the air conditioner is running at different frequencies can be obtained by simulation test.

[0080] Step S3, based on the sound quality model constructed, the sound quality parameter values corresponding to the different parameter values of the k material parameters of the panel at different panel temperatures when the air conditioner is running at different frequencies, the sound power and mode of the panel at different panel temperatures when the air conditioner is running at different frequencies and the parameter values of the k material parameters, the corresponding relationship between the running frequency and the panel temperature of the air conditioner is established.

[0081] Figure 3 A step flow chart of one specific embodiment of establishing the corresponding relationship between the running frequency and the panel temperature of the air conditioner according to the present application is shown. As shown in Figure 3 In one specific embodiment, establishing the corresponding relationship between the running frequency and the panel temperature of the air conditioner includes the following steps S31-S33:

[0082] Step S31, according to the sound power and mode of the panel at different panel temperatures when the air conditioner is running at different frequencies and the values of the k material parameters of the panel at different panel temperatures, the relationship between the panel temperature and the k material parameters of the panel when the air conditioner is running at different frequencies is fitted by a first preset algorithm.

[0083] For example, according to the sound power and mode of the panel at different panel temperatures when the air conditioner is running at different frequencies, the panel temperature and the values of the k material parameters when the sound quality is optimal are determined (the mode is the inherent characteristic of the panel material, the mode changes, and the sound quality changes accordingly, so by testing the sound power and mode of the panel at different panel temperatures when the air conditioner is running at different frequencies, the panel temperature and the values of the k material parameters when the sound quality is optimal can be determined from the sound power and mode), the relationship between the panel temperature y and the k material parameters x1-xk when the sound quality is optimal is a linear relationship: y=a+bx, where x takes the values of the parameter values of the k material parameters x1-xk, and y takes the values of y1-yk. The first preset algorithm can be linear interpolation, for example.

[0084] Step S32, according to the sound quality model and the sound quality parameter values corresponding to the different parameter values of the k material parameters of the panel at different panel temperatures when the air conditioner is running at different frequencies, the relationship between the panel temperature and the sound quality parameter of the air conditioner when the air conditioner is running at different frequencies is fitted by a second preset algorithm.

[0085] For example, the relationship between the panel temperature y of the panel and the sound quality F of the air conditioner when the air conditioner is running at different frequencies is a linear relationship F = c + dy, where y takes values y1 ~ yk, and F takes values F N , sharpness F S , roughness F R ; the second preset algorithm can be least squares method.

[0086] In the above formula, a, b, c, d all have the value of k, and x1 ~ xk are substituted into the initial value.

[0087] Step S33, according to the relationship between the panel temperature and the k material parameters and the relationship between the panel temperature and the sound quality parameter of the air conditioner, the corresponding relationship between the running frequency of the air conditioner and the panel temperature is iterated.

[0088] Specifically, the panel temperature will affect the parameter values of the k material parameters x1, x2, …, x k , by assigning an initial temperature, there will be an initial parameter value X (including the initial parameter values of x1 ~ xk), these material parameters affect the inherent characteristics of the panel, when the panel temperature changes, the material parameters change, the inherent characteristics of the panel (i.e. the modal of the panel) change. When the air conditioner is running at different frequencies, the modal of the panel changes, and the sound quality changes, according to the experimental test data, the relationship between the panel temperature and the k material parameters x1, x2, …, x k , the relationship between the panel temperature and the sound quality (loudness, sharpness and roughness) is fitted, and the initial value is substituted, according to the two relationship formulas, the better temperature value and the sound quality result of the air conditioner running at different frequencies can be iterated, that is, the panel temperature corresponding to the optimal sound quality of the air conditioner running at different frequencies.

As Figure 4 The sound quality system includes loudness model, sharpness model, roughness model, by assigning initial values to the k material parameters, inputting the simulation software to perform modal analysis and acoustic analysis to obtain the sound power and modal of the panel corresponding to the different parameter values of the k material parameters of the air conditioner when the air conditioner is running at different frequencies.

[0091] Specifically, according to the correspondence relationship between the operating frequency of the air conditioner and the panel temperature, and the current operating frequency of the air conditioner, the panel temperature corresponding to the optimal sound quality of the air conditioner at the current operating frequency can be obtained, and the panel temperature is taken as the current target panel temperature.

[0092] The control unit 130 is configured to control the panel temperature by controlling a temperature control device on the panel, so that the panel reaches the target panel temperature, and the temperature control device includes a heating device and a cooling device.

The panel is also provided with a temperature sensor, which can detect the panel temperature, and the heating device is controlled to heat the panel or the cooling device is controlled to cool the panel according to the panel temperature detected by the temperature sensor.

For example, when the area covered by bacteria and / or dust in the internal area of the air conditioner reaches 30%, the user is reminded to do simple disassembly and cleaning work; when the area covered by bacteria and / or dust in the internal area of the air conditioner reaches 60%, the user is reminded to need a professional to disassemble and clean the service.
