Description

Technical Field

[0001] This application relates to the field of noise reduction technology for range hoods, and in particular to a temperature control method, device, electronic device, and readable storage medium. Background Technology

[0002] Range hoods have become an essential appliance in most family kitchens, capable of quickly removing harmful fumes produced during cooking and expelling them outdoors, thus maintaining a clean kitchen environment.

[0003] As living standards improve, consumers have increasingly higher requirements for the performance of range hoods. However, range hoods usually generate noise during operation, affecting the user experience. Existing noise reduction technologies mainly focus on the following aspects: 1. Arranging sound-absorbing materials or structures, such as sound-absorbing cotton, sound-absorbing metamaterials, silencers, etc.; 2. Optimizing the volute profile to change the flow field; 3. Active noise reduction, using sound-generating devices to emit sounds with the opposite phase to the noise, achieving a mutual cancellation effect.

[0004] The noise from a range hood primarily propagates outwards from the air inlet and duct, while very little noise is transmitted through the fan frame. Range hoods designed using the principle of total internal reflection allow normal air intake, but the noise is only dissipated within the unit, preventing it from spreading outwards and significantly reducing noise levels. However, the success and effectiveness of total internal reflection largely depend on the uniformity of the temperature of the acoustically less dense medium layer. In reality, during operation, the velocity distribution varies at different locations within the air inlet grille, resulting in different heat loss within the same timeframe. Consequently, the acoustically less dense medium layer formed at the grille is uneven, affecting the effectiveness of total internal reflection and thus the noise reduction. Summary of the Invention

[0005] To address the technical problem of uneven temperature at the air inlet of existing range hood grilles affecting noise reduction, this invention provides a temperature control method, device, electronic equipment, and readable storage medium. Within a calibrated set of preset power schemes, the power of multiple temperature control devices is determined based on the range hood's speed setting and exhaust pressure. By adjusting the power of these multiple temperature control devices, the temperature at the air inlet of the range hood grille becomes uniform, ultimately achieving total sound reflection and ensuring the noise reduction effect of the range hood.

[0006] In a first aspect, embodiments of this application provide a temperature control method applied to a range hood grille, wherein multiple temperature control devices are installed on the range hood grille; the method includes:

[0007] Obtain the current speed setting and current pressure data of the exhaust vent of the range hood;

[0008] If a preset power scheme exists in the preset power scheme set corresponding to the current gear data and the current pressure data, then obtain the preset power scheme corresponding to the current gear data and the current pressure data. The preset power scheme set includes multiple preset power schemes. The preset power scheme corresponding to the current gear data and the current pressure data represents the power corresponding to multiple temperature control devices that achieve total reflection of sound inside the range hood when the range hood is at the current gear and the pressure at the exhaust port is the current pressure.

[0015] The first pressure data is the adjacent pressure data in the preset power scheme set that is lower than the current pressure data; the preset pressure difference is the difference between adjacent pressure data in the preset power scheme set; the second pressure data is the adjacent pressure data in the preset power scheme set that is higher than the current pressure data.

[0018] Obtain the first power scheme set corresponding to each standard pressure data;

[0019] If there is a first power scheme in the first power scheme set that satisfies the first preset condition, then the set of first power schemes that satisfies the first preset condition and satisfies the second preset condition is determined as the preset power scheme corresponding to the gear data and the standard pressure data.

[0020] In one optional embodiment, obtaining a set of multiple first power schemes corresponding to each standard pressure data includes:

[0021] With the exhaust vent pressure at standard pressure, first temperature data and second temperature data are acquired; the first temperature data is the air temperature data inside the range hood; the second temperature data is the air temperature data at a temperature control device.

[0022] Increase the operating power of the temperature control equipment;

[0023] Under the condition that the first temperature data and the second temperature data satisfy the preset total reflection relationship, the operating power of the acquired temperature control device is used as the reference power data corresponding to the standard pressure data.

[0024] The power fluctuation range is divided into intervals with a preset power difference, and multiple standard power data corresponding to the standard pressure data obtained from the division are obtained; the power fluctuation range is based on the reference power data and fluctuates up and down with a preset fluctuation value.

[0025] Obtain the first power scheme set; the first power scheme set is a set of standard power data for multiple temperature control devices.

[0026] In an optional embodiment, if a first power scheme that satisfies a first preset condition exists in the first power scheme set, a set of first power schemes that satisfy a second preset condition and satisfy the first preset condition is determined as a preset power scheme corresponding to the gear data and the standard pressure data, including:

[0027] Obtain the third temperature data set corresponding to each first power scheme in the first power scheme set; the third temperature data set includes the third temperature data at each temperature control device.

[0028] If the difference between the third temperature data and the second temperature data corresponding to the first power scheme is less than the preset temperature difference, the set of the first power schemes that meets the second preset condition and satisfies the first preset condition is determined as the preset power scheme corresponding to the gear data and the standard pressure data.

[0029] In one optional embodiment, after obtaining the first power scheme set corresponding to each standard pressure data, the method further includes:

[0030] If there is no first power scheme that meets the first preset condition in the first power scheme set, increase the preset fluctuation value of the power fluctuation range of the temperature control device to obtain the second power scheme set;

[0031] If there is a second power scheme in the second power scheme set that satisfies the first preset condition, then the set of second power schemes that satisfies the first preset condition is determined as the preset power scheme corresponding to the gear data and the standard pressure data.

[0032] In an optional embodiment, if no first power scheme that meets the first preset condition exists in the first power scheme set, the upper and lower fluctuation values ​​of the power fluctuation range of the temperature control device are increased. After obtaining the second power scheme set, the method further includes:

[0033] If the second power scheme in the second power scheme set does not have a trend of satisfying the first preset condition, the preset power difference value for dividing the power fluctuation range is reduced to obtain the third power scheme set.

[0034] If there is a third power scheme in the third power scheme set that satisfies the first preset condition, then the set of third power schemes that satisfies the first preset condition and satisfies the second preset condition is determined as the preset power scheme corresponding to the gear data and the standard pressure data.

[0050] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0051] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of this application described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion; for example, a process, method, system, product, or server that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or devices.

[0052] Please see Figure 1 , Figure 1 This is a schematic diagram of an application environment provided in an embodiment of this application, including multiple temperature control devices installed on the range hood grille.

[0053] When sound travels from a medium with a higher refractive index to a medium with a lower refractive index, if the angle of incidence is greater than a certain critical angle, the refracted sound wave will disappear, and all the incident sound waves will be reflected and will not enter the medium with the lower refractive index.

[0054] The speed of sound in air is related to temperature as follows: As temperature increases, sound waves travel faster. Therefore, air, which has a relatively low temperature, is an acoustically dense medium, while air, which has a relatively high temperature, is an acoustically rarefied medium.

[0055] In this embodiment, the acoustically tight medium is the air inside the range hood. In order to detect the air temperature inside the range hood, a first temperature sensor is installed inside the range hood.

[0056] In this embodiment, the acoustic medium is a thin layer of air at the grille of the range hood. With the above arrangement, the sound waves can achieve total reflection and be transmitted only inside the range hood, so that the air inlet can be normally ventilated, but the noise will not be transmitted from the air inlet.

[0057] In one alternative embodiment, such as Figure 1 As shown, multiple temperature control devices are evenly arranged on the range hood grille. Specifically, the temperature control devices are configured as heating tubes 101 installed in the range hood grille. In order to accurately obtain the temperature at each heating tube 101, a second temperature sensor 102 is provided for each heating tube 101. The second temperature sensor 102 is located on the outer wall of the range hood grille, which can more easily sense the temperature of the thin air layer at the range hood grille.

[0058] In this embodiment of the application, the heating tubes 101 are specifically configured to be m, and correspondingly, the second temperature sensors 102 are also configured to be m.

[0059] In one alternative embodiment, to make the air layer at the range hood grille more uniform, a fan blowing air relative to each other can be installed at the range hood grille to promote temperature uniformity of the acoustically rarefied medium layer.

[0060] The following describes a specific embodiment of a temperature control method according to this application. Figure 2 This is a flowchart illustrating a temperature control method provided in an embodiment of this application. This specification provides the method operation steps as shown in the embodiments or flowcharts, but based on conventional or non-inventive methods, more or fewer operation steps may be included. The order of steps listed in the embodiments is merely one possible execution order among many and does not represent the only possible execution order. In actual system or server product execution, the method can be executed sequentially according to the embodiments or drawings, or in parallel (e.g., in a parallel processor or multi-threaded processing environment). Specifically, as shown... Figure 2 As shown, this method, applied to a range hood grille, may include:

[0061] S201: Obtain the current speed setting data and the current pressure data of the exhaust vent of the range hood.

[0062] S202: If a preset power scheme corresponding to the current gear data and the current pressure data exists in the preset power scheme set, obtain the preset power scheme corresponding to the current gear data and the current pressure data; the preset power scheme set includes multiple preset power schemes; the preset power scheme corresponding to the current gear data and the current pressure data represents the power corresponding to multiple temperature control devices that achieve total reflection of sound inside the range hood when the gear of the range hood is the current gear and the pressure of the exhaust port is the current pressure.

[0063] S203: Controls the power of multiple temperature control devices according to the preset power scheme corresponding to the current gear data and the current pressure data.

[0064] Figure 3 This is a flowchart illustrating a temperature control method provided in an embodiment of this application. The method may include:

[0065] S301: Obtain the current speed setting data and the current pressure data of the exhaust vent of the range hood.

[0066] In one optional embodiment, the range hood exhaust vent is connected to a shared flue. Multiple households share the same flue, and the usage of range hoods by different households varies constantly. At certain times, multiple range hoods may be running simultaneously, while at other times they may not. In this situation, the airflow pressure within the shared flue is constantly affected, causing pressure fluctuations at the exhaust vent. Simultaneously, weather conditions and changes in air pressure can affect airflow inside and outside the building. When the intensity and direction of external wind change, it also affects the airflow within the shared flue, thus causing pressure fluctuations at the exhaust vent.

[0067] Therefore, at the same setting, the exhaust vent pressure will fluctuate within a certain range. Different pressures correspond to different airflow velocity distributions at the air inlet. The airflow velocity distribution is different at different positions of the grille, and the amount of heat carried away in the same amount of time is different. In order to ensure the uniformity of temperature of the thin layer of acoustic medium at the grille, each combination of pressure and heating tube power needs to be calibrated sequentially. Therefore, the heating tube power and the current setting of the range hood will affect the heating tube power at the current moment.

[0068] In the embodiments of this application, the range hood has three speed settings: high, medium, and low. At each speed setting, it is necessary to calibrate the combination scheme of each pressure and heating element power.

[0069] S302: Determine whether the preset power scheme set contains the preset power scheme corresponding to the current gear data and the current pressure data. If it exists, execute S303; if it does not exist, execute S304.

[0070] In the embodiments of this application, the preset power scheme set includes a series of preset power schemes. There is a corresponding relationship between the preset power scheme and the current gear data and the current pressure data. That is to say, a unique preset power scheme can be located by using the current gear data and the current pressure data.

[0071] Since the current gear data is finite and discrete, the corresponding gear can be found in the preset power scheme set. However, the pressure fluctuation range is a continuous range, and the pressure calibration is discrete. Therefore, there are cases where the current pressure data does not have a completely corresponding pressure data.

[0072] In this embodiment of the application, the current gear level is low and the current pressure is p. a If the preset power scheme set contains a range hood with a low setting and an exhaust pressure of p, a At that time, the power corresponding to the multiple heating elements that achieve total reflection of sound inside the range hood is determined. The preset power scheme set contains preset power schemes corresponding to the current gear level and current pressure data. If P is not present in the preset power scheme set... a The corresponding preset power scheme, then whether there is a preset power scheme in the preset power scheme set corresponding to the current gear data and the current pressure data.

[0073] It should also be noted that, in order to distinguish between the symbols for pressure and power, pressure is represented by the lowercase letter p, and power is represented by the lowercase letter P.

[0074] S303: Obtain the current gear data and the preset power scheme corresponding to the current pressure data.

[0075] In this embodiment, the preset power scheme corresponding to the current gear level data and the current pressure data represents the power of the m heating tubes that enable total reflection of sound inside the range hood when the range hood is at the current gear level and the pressure at the exhaust port is the current pressure.

[0076] S304: Determine whether the difference between the current pressure data and the first pressure data is less than or equal to half of the preset pressure difference value. If yes, execute S305; otherwise, execute S306.

[0077] In one alternative embodiment, the first pressure data p b The second pressure data is the adjacent pressure data in the preset power scheme set that is less than the current pressure data; c The preset pressure difference k1 is the difference between adjacent pressure data in the preset power scheme set that is greater than the current pressure data. Specifically, p b <p a <p c, and p c -p b =k1.

[0078] S305: Obtain the preset power scheme corresponding to the first pressure data as the current gear data and the preset power scheme corresponding to the current pressure data.

[0079] In this embodiment of the application, the current pressure data p a Compared with the first pressure data p b If the difference is less than or equal to half of the preset pressure difference value k1, it indicates that compared to the second pressure data p c Current pressure data p a Closer to the first pressure data p b Therefore, the first pressure data p is selected. b The corresponding preset power scheme is used as the current pressure data p a The corresponding preset power scheme.

[0080] S306: Obtain the preset power scheme corresponding to the second pressure data as the current gear data and the preset power scheme corresponding to the current pressure data.

[0081] In this embodiment of the application, the current pressure data p a Compared with the first pressure data p b If the difference is less than or equal to half of the preset pressure difference value k1, it means that compared to the first pressure data p b Current pressure data p a Closer to the second pressure data p c Therefore, the second pressure data p is selected. c The corresponding preset power scheme is used as the current pressure data p a The corresponding preset power scheme.

[0082] S307: Controls the power of multiple temperature control devices according to the preset power scheme corresponding to the current gear data and the current pressure data.

[0083] In actual operation of the range hood, the combination scheme of heating tube power is directly matched with the preset power scheme through circuit control, thereby ensuring the uniformity of temperature of the acoustically rarefied medium thin layer. With the slight fluctuation of the exhaust port pressure, the power combination scheme of m heating tubes is continuously adjusted and controlled so that the power of the heating tubes adapts to the pressure change, and the temperature at the grille is always kept in a stable and uniform state, resulting in a temperature-stable and uniform acoustically rarefied medium thin layer.

[0084] Figure 4 This is a flowchart illustrating a method for calibrating a set of preset power schemes, provided in an embodiment of this application, applied to a range hood grille. The method may include:

[0085] S401: Divide multiple pressure fluctuation ranges at preset pressure difference intervals and obtain multiple standard pressure data after division.

[0086] Among them, multiple pressure fluctuation ranges correspond to multiple speed settings of the range hood.

[0087] In this embodiment of the application, for the low setting of the range hood, the exhaust pressure p will have a fluctuation range (p min p max ), with a preset pressure difference value k1 as the interval, (p min p max The data is divided into multiple standard pressure data points. min p2, p3...p max .

[0088] S402: Obtain the first power scheme set corresponding to each standard pressure data.

[0089] In this embodiment of the application, the method for obtaining the first power scheme set corresponding to each standard pressure data is as follows:

[0090] S412: The pressure at the exhaust outlet is the standard pressure data p. a In this case, that is, under standard pressure data p min p2, p3...p max There exists p a In this case, acquire the first temperature data and the second temperature data.

[0091] The first temperature data is the air temperature data T1 in the range hood, which is obtained by the first temperature sensor installed in the range hood; the second temperature data is the air temperature data T2 at a heating element, which is obtained by the second temperature sensor installed on the grille.

[0092] S422: Increase the working power of the heating element.

[0093] In the embodiments of this application, the heating power of the heating tubes increases from 0.

[0094] S432: Under the condition that the first temperature data and the second temperature data satisfy the preset total reflection relationship, the operating power of the acquired temperature control device is used as the reference power data P0 corresponding to the standard pressure data.

[0095] In one optional embodiment, the preset total internal reflection relationship is: θ is the incident angle of the sound wave. The pre-defined total internal reflection relationship means that when the first temperature data and the second temperature data satisfy... At that time, the sound waves that propagate to the grille temperature control device at the incident angle θ can be completely reflected back into the range hood at the reflection angle θ, realizing the circulation of noise inside the range hood, so that the air inlet can enter normally, but the noise will not be transmitted from the air inlet.

[0096] At this point, the reference power data P0 is not consistent with the flow field velocity distribution, and not all data from the second temperature sensor meet the requirements. Therefore, it is necessary to find a power combination scheme that satisfies the preset total reflection relationship for all other second temperature sensors, based on the reference power data P0.

[0097] S442: Divide the power fluctuation range into intervals with a preset power difference, and obtain multiple standard power data corresponding to the standard pressure data obtained from the division.

[0098] In this embodiment, the power fluctuation range is based on a reference power data and fluctuates up and down by a preset fluctuation value. Specifically, the power fluctuation range is (P0-dp, P0+dp), and the preset power difference is k2. The power fluctuation range (P0-dp, P0+dp) is evenly divided into... Each value can be selected.

[0099] S452: Obtain the first power scheme set.

[0100] In one possible embodiment, the first power scheme set is a set of multiple temperature control devices, each representing a set of multiple standard power data.

[0101] In this embodiment of the application, since there are m heating tubes, the power combination scheme (P1, P2, P3...P) is... m )have A combination of schemes.

[0102] S403: Determine whether there is a first power scheme in the first power scheme set that satisfies the first preset condition. If yes, execute S404; otherwise, execute S405.

[0103] In one possible embodiment, the first preset condition is that the difference between the third temperature data corresponding to the first power scheme and the second temperature data is less than a preset temperature difference value Δt, and the third temperature data is T. i The preset temperature difference Δt is calculated by computer and is the maximum given error.

[0104] Calculate max|T using computer calculations. i -T2|≤△t, if the max|T of the first power scheme i -T2|≤△t indicates that the third temperature data T i The maximum difference between the third temperature data T and the second temperature data T2 is less than the preset temperature difference value Δt.i The difference between the temperature data T2 and the second temperature data T2 is less than the preset temperature difference value △t. At this time, the second temperature data at the grid corresponding to the first power scheme is within the range of the maximum error △t.

[0105] In this embodiment, the preset temperature difference Δt is a very small value, so that the second temperature data within this error range is also close to the preset total reflection relationship.

[0106] S404: Among the first power schemes that meet the first preset condition, a set that meets the second preset condition is determined as the preset power scheme corresponding to the gear data and the standard pressure data.

[0107] In one possible embodiment, the second preset condition is max|T i -T2| Select the group with the smallest value, that is, find the group with the most stable temperature within the range of the maximum error Δt. This power combination scheme makes the third temperature data T i It not only closely approximates the second temperature data T2, but also exhibits the most stable and uniform temperature.

[0108] In this application and embodiments, the power combination scheme is used as the calibrated low setting with a pressure of p. a The corresponding preset power scheme.

[0109] S405: Increase the upper and lower fluctuation values ​​of the power fluctuation range of the temperature control equipment to obtain the second power scheme set.

[0110] The second power scheme set here refers to the power scheme after increasing the upper and lower fluctuation values ​​of the power fluctuation range of the temperature control equipment.

[0111] If at this point the minimum max|T i If -T2|>△t, then the fluctuation range of the reference power data P0 will be expanded. The fluctuation range of the power of the temperature control device can be uniform or non-uniform.
