Description

Technical Field

[0001] This invention relates to the field of kitchenware technology, and in particular to noise control methods, devices, electronic equipment, and storage media. Background Technology

[0002] A range hood is a kitchen appliance designed to purify the kitchen environment. It works by using a centrifugal fan installed inside the hood to draw in and exhaust cooking fumes. The centrifugal fan consists of a volute, an impeller housed within the volute, and a motor that drives the impeller. When the impeller rotates, a negative pressure is generated at the center of the fan, drawing in the cooking fumes from below. After being accelerated by the fan, the volute collects the fumes and guides them outdoors. Therefore, range hoods generate considerable noise during operation, a significant noise source in homes that impacts user experience and has become an important factor for consumers when purchasing such products. R&D engineers at various manufacturers have conducted extensive research on vibration and noise reduction for range hoods, resulting in continuous noise reduction and improved user experience.

[0003] However, noise issues with range hoods in actual user working environments lead to customer complaints and even returns / replacements. When noise problems arise, R&D engineers need to solve them; if the noise problem cannot be resolved, the user experience suffers, and customer returns / replacements increase the operating costs for range hood manufacturers.

[0075] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0076] To facilitate understanding of this embodiment, the application scenarios and design concepts of this application embodiment will be briefly introduced below.

[0077] When noise problems occur in the user's actual working environment, R&D engineers need to arrive on-site in time to solve the noise problem. The degree of automation is low, the amount of manual labor is large, and when the noise problem cannot be solved quickly, the user experience is poor and the return and replacement of the machine by the customer increases the operating cost of the range hood manufacturer.

[0078] Based on this, embodiments of this application provide a noise control method, device, electronic device, and storage medium to enable the range hood to adaptively adjust and reduce noise when noise problems occur, thereby improving the degree of automation.

[0079] Example 1

[0080] This application provides a noise control method applied to a controller within a smoke machine control system. The controller includes a processor and a memory; the memory stores a computer program, and the processor processes the computer program to implement the noise control method provided in this application.

[0081] Combination Figure 1 As shown, the method includes:

[0082] S110, the processor obtains the noise parameters of the range hood at various operating levels.

[0083] S120: For each operating level, the processor determines whether the noise parameter corresponding to the operating level is greater than the preset noise threshold.

[0084] If so, proceed with steps S130-S160.

[0085] S130, the processor has determined that the noise level of the operating gear is unacceptable.

[0086] S140, the processor calculates noise characteristic values ​​based on noise parameters and noise thresholds.

[0087] S150, the processor determines the noise level based on the comparison between the noise characteristic value and the preset threshold.

[0088] S160, the processor controls the range hood to operate in a working mode corresponding to the noise level.

[0089] The noise control method provided in this application compares the noise parameters of the range hood at various operating levels with preset noise thresholds. When the noise parameters exceed the thresholds, the noise is determined to be substandard. Then, based on the noise parameters and thresholds, a noise characteristic value is calculated. The noise level is determined by comparing the noise characteristic value with the preset thresholds. The range hood is then controlled to operate in the mode corresponding to the noise level. This method specifically addresses noise substandard issues at different noise levels, improves the degree of automation, reduces the difficulty of manual adjustment, enhances user experience, and reduces the manufacturer's operating costs.

[0090] In conjunction with the first aspect, the steps for S110 to obtain the noise parameters of the range hood at various operating levels include:

[0091] S111, the processor obtains the time-domain and frequency-domain characteristic parameters of the range hood at each operating level;

[0092] S112, for each operating level, the processor calculates the mean of the time-domain characteristic parameters and the frequency-domain characteristic parameters to obtain the noise parameters corresponding to the operating level.

[0093] Specifically, the S111 processor acquires the time-domain and frequency-domain characteristic parameters of the range hood at various operating levels, including:

[0094] S1110, the processor acquires the first sound signal of the range hood under various operating conditions. The operating conditions should include at least three levels: low, high, and high-power (stir-fry). These three levels are the three commonly set levels for range hoods, but as the number of preset levels increases, the number of first sound signals acquired also increases. The component used to acquire the first sound signal can be any type of sound sensor, such as a microphone or noise sensor. In this embodiment, according to the new national standard noise testing method, the first sound signal of the range hood under the low, high, and high-power (stir-fry) conditions is acquired, and the acquired first sound signal is transmitted to the controller every time interval t0. As an example, in this embodiment, t0 = 30s.

[0095] S1111, the processor uses the point corresponding to the peak value in the first sound signal as the signal center point, and extracts a sound signal of a set duration as the second sound signal. Specifically, it selects a portion of the first sound signal of duration t0 for a set duration t. x The sound signal is used as the second sound signal. That is, t x ≤t0.

[0096] In conjunction with the above example, take t x =10s. Obtain the total number of sample points N from the first sound signal with a duration of t0=30s, select the sample point N corresponding to the first sound peak as the signal center point, and extract from both the left and right sides of the N point sample points on each side. In this way, a first sound signal with a length of t x =10s can be intercepted as the second sound signal.

[0097] In S1112, the processor performs feature extraction on the second sound signal to obtain time-domain feature parameters and frequency-domain feature parameters. The time-domain feature parameters include the time-domain mean value of sound pressure and the time-domain peak value of sound pressure; the frequency-domain feature parameters include the frequency-domain feature of sound pressure and the frequency-domain peak value of sound pressure.

[0098] After that, for any operating gear, the mean values of the time-domain feature parameters and the frequency-domain feature parameters are calculated through S112 to obtain the noise parameter corresponding to this operating gear.

[0099] That is, A=(A 时域 +A 频域 )÷2; where A is the noise parameter, A 时域 is the time-domain feature parameter, A 频域 is the frequency-domain feature parameter.

[0100] After that, the processor judges the comparison relationship between A and the preset noise threshold Q through S120. When A>Q, the processor executes S130 to S160. In S130, the processor determines that the noise is unqualified, and further determines the noise level in steps S140 to S150. After that, in step S160, the processor operates according to the working mode corresponding to the noise level to reduce noise.

[0101] In conjunction with the first aspect, S140, the step in which the processor calculates the noise characteristic value according to the noise parameter and the noise threshold specifically includes:

[0102] Calculate the noise characteristic value using the following formula:

[0103] T=(A-Q)÷Q;

[0104] where T is the noise characteristic value, A is the noise parameter, and Q is the preset noise threshold.

[0105] In conjunction with the first aspect, the step in which the processor in S150 determines the noise level of the noise according to the comparison relationship between the noise characteristic value and the preset threshold, in conjunction with Figure 2 as shown, specifically includes:

[0106] If T<T1, the processor determines that the noise level is a first-level noise.

[0107] If T1<T≤T2, the processor determines that the noise level is level 2 noise.

[0108] If T>T2, the processor determines that the noise level is level 3 noise.

[0109] Wherein, T is the noise characteristic value, T1 is the first set threshold, T2 is the second set threshold, and T1<T2.

[0110] In this embodiment, T1=5%; T2=10%. In the actual application process, the values can be modified according to the actual situation, which is not limited herein.

[0111] In combination with the first aspect, the noise level is level 3 noise. The step S160 in which the processor controls the range hood to operate in the operation mode corresponding to the noise level includes:

[0112] In response to a touch operation for the first designated key, the fan is controlled to operate in the first mode until the fan stops.

[0113] In response to a user's touch operation for the second designated key, a first air oil fume concentration is acquired.

[0114] It is determined whether the first air oil fume concentration is greater than an oil fume concentration threshold.

[0115] If yes, the fan is controlled to operate in the second mode.

[0116] A first current noise level after the fan operates in the second mode is acquired.

[0117] It is determined whether the first current noise level is level 3 noise.

[0118] If yes, the fan is controlled to operate in the second mode until the first current noise level is converted to level 2 noise or level 1 noise.

[0119] The fan is controlled to operate in the operation mode corresponding to level 2 noise or level 1 noise until the noise is qualified.

[0120] In combination with the first aspect, after the step of determining whether the first air oil fume concentration is greater than the oil fume concentration threshold, the method further includes:

[0121] If not, the fan is controlled to operate in the third mode;

[0122] A second current noise level after the fan operates in the third mode is acquired;

[0123] It is determined whether the second current noise level is level 3 noise;

[0124] If yes, the fan is controlled to operate in the fourth mode until the second current noise level is converted to level 2 noise or level 1 noise;

[0125] Control the fan to operate in a working mode corresponding to Level 2 or Level 1 noise until the noise level meets the requirements.

[0126] In this embodiment, the first mode controls the fan speed to decrease by 10% every 3 seconds; the second mode controls the fan speed to decrease by 3%; the third mode controls the fan speed to decrease by 2%; the fourth mode controls the fan speed to decrease by 5%; and the fifth mode controls the fan speed to decrease by 4%.

[0127] In this embodiment, the first designated key is the power off key, and the second designated key is the continue running key. As one possible implementation, these two designated keys can be embedded in the range hood panel or protrude from the panel. Startup can be selected by pressing or touching the screen.

[0128] Specifically, when the noise level is level three, it indicates that the noise is very loud. In response to the user's shutdown operation, the fan is controlled to run in the first mode until the fan stops. That is, when the user chooses to shut down the machine because they feel that the noise is too loud, the fan speed is controlled to decrease by 10% every 3 seconds until it stops.

[0129] If the noise level is level three but the user still chooses to continue operating, the first air fume concentration is obtained and compared with the preset fume concentration threshold Y0. Based on the comparison result, the fan operation is controlled to change the noise level to level one or level two. Then, adjustments are made according to the corresponding working mode until the noise level is qualified.

[0130] Here is an example:

[0131] For example, the current fan speed is r0 = 50 r / min, and the noise level is level three; the preset oil fume concentration threshold is Y0.

[0132] If the user chooses to continue running, first obtain the first air fume concentration Y1.

[0133] If Y1>Y0, then control the fan speed to decrease by 3%, and determine the first current noise level after the fan speed is reduced. If it is still the current level three noise, then control the fan speed to decrease periodically by 2% until the noise is alleviated to level two or level one noise.

[0134] Based on the above example, the fan speed after the initial speed reduction is r1 = r0 × (1-3%) = 48.5 r / min. If the noise level is still at level three, the fan speed will be reduced by 2% per unit time. For example, after the first cycle, r2 = r1 × (1-2%) = 47.53 r / min, and in the second cycle, r3 = r2 × (1-2%) = 46.58 r / min, until the noise level is converted to level two or level one. Then, the fan will operate according to the corresponding working mode for level two or level one noise until the noise level is acceptable. If the noise is alleviated after the initial speed reduction and has been converted to level two or level one noise, then the fan will operate according to the working mode corresponding to the specific noise level until the noise level is acceptable.

[0135] If Y1≤Y0, that is, if the first air fume concentration is not greater than the preset fume concentration threshold Y0, the fan is controlled to operate in the fourth mode, that is, the speed is controlled to decrease by 5%, i.e., r1'=r0×(1-5%).

[0136] Next, the second current noise level after the speed reduction is judged again. If the noise has been alleviated and converted to level two or level one noise, then the operation is carried out according to the working mode corresponding to the specific noise level until the noise is qualified. If the noise is still at level three, the fan is controlled to operate in the fifth mode, that is, the fan speed is reduced by 4% until the noise is alleviated. Then, the operation is carried out according to the working mode corresponding to the specific noise level (level one or level two noise) until the noise is qualified.

[0137] In summary, when the noise level is level three and the user still chooses to operate the system, it is necessary to first determine the relationship between the initial air fume concentration and the preset fume concentration threshold Y0. Different methods are then used to mitigate the noise problem based on the different relationships, aiming to reduce the noise level to level two or level one. Afterward, the system is operated according to the corresponding operating mode for level two or level one noise to further reduce noise. This achieves automatic and gradual noise reduction.

[0138] Preferably, the smoke hood control system also includes an alarm device that issues a noise alarm when the noise level is equal to level three.

[0139] Combination Figure 2 As shown, under noise level level two, the control of the smoke hood to operate in the working mode corresponding to the noise level specifically includes:

[0140] In response to the user's touch operation on the third designated key, the fan is controlled to operate in the sixth mode until the fan stops.

[0141] In response to the user's touch operation on the fourth designated key, the second air fume concentration is obtained.

[0142] Determine whether the concentration of oily fumes in the second air is greater than the preset oily fume concentration threshold.

[0143] If so, control the fan to operate in mode seven.

[0144] Obtain the third current noise level of the fan after it has been running in the seventh mode.

[0145] Determine whether the current noise level is level two.

[0146] If so, control the fan to operate in mode eight until the current noise level of level three is converted to level one.

[0147] Control the fan to operate in the working mode corresponding to the first-level noise level until the noise level meets the standard.

[0148] In this embodiment, the sixth mode controls the fan speed to decrease by 10% every 3 seconds; the seventh mode controls the fan speed to decrease by 2%; and the eighth mode controls the fan speed to decrease by 1%.

[0149] As one feasible approach, the third designated key is the same as the first designated key for powering off; the fourth designated key is the same as the second designated key for continuing to run.

[0150] When the noise level is level two, the handling method is similar to that for level three noise. If the user continues to operate the system, the second air fume concentration is first obtained to determine whether it exceeds the preset fume concentration threshold Y0. Based on the determination result, different operating modes are adopted to alleviate the noise until the noise level is reduced to level one. Then, the system is operated according to the working mode corresponding to level one noise to gradually alleviate the noise problem.

[0151] Specifically, in combination Figure 2 As shown, in step S210, if the noise level is determined to be level two, step S220 responds to the user's touch operation on the third designated key and controls the fan to operate in the seventh mode. That is, when the user touches the power off key, the fan speed is reduced by 10% every 3 seconds until the fan stops.

[0152] Step S230 responds to the user's touch operation on the fourth designated key and obtains the second air fume concentration. That is, after the user touches the button to continue operation, the second air fume concentration Y2 is obtained.

[0153] Step S240 determines whether the second air fume concentration is greater than the preset fume concentration threshold. That is, it determines whether Y2 is greater than Y0. If yes, proceed to steps S250-S280. If no, proceed to steps S251-S281.

[0154] When Y2>Y0, the fan is controlled to operate in mode seven, i.e., step S250 controls the fan speed to decrease by 2%. After obtaining the third current noise level after the fan operates in mode seven, step S260 determines whether the third current noise level is level two noise, i.e., whether the value of (AQ)÷Q at the current moment is still between 5% and 10%. If so, step S270 controls the fan to operate in mode eight until the third current noise level changes to level one noise. That is, the fan speed is controlled to decrease by 1% until (AQ)÷Q<5%, i.e., after the speed decreases by 1% per unit time, it is determined whether it is still level two noise. If so, the fan speed is repeatedly controlled to decrease by 1% until the noise is reduced to level one noise. Then, step S280 controls the fan to operate in the working mode corresponding to level one noise until the noise is acceptable.

[0155] When Y2≤Y0, the fan is controlled to operate in the tenth operating mode. In this embodiment, the tenth operating mode is to reduce the fan speed by 3%. That is, in step S251, the fan speed is reduced by 3%. After obtaining the current fourth noise level, step S261 determines whether the fourth noise level is level two. That is, it determines whether the value of (AQ)÷Q at the current time is still between 5% and 10%; if so, the fourth noise level is still level two after the speed reduction. If so, step S271 controls the fan to operate in the eleventh mode until the fourth noise level changes to level one. In this embodiment, the eleventh mode is to reduce the fan speed by 2%. Afterwards, step S281 is executed to control the fan to operate in the working mode corresponding to level one noise until the noise level is acceptable.

[0156] Preferably, when the noise level is determined to be level two, an alarm device should also be activated to indicate that the noise has exceeded the threshold. This alarm can be different from the alarm for level three noise. For example, a voice output alarm can be used, with different preset voices to help users or equipment maintenance personnel quickly identify the current noise level. Alternatively, different colored indicator lights or light displays of different durations can also be used to provide separate alarms.

[0157] In conjunction with the first aspect, the noise level is Level 1; step S160, controlling the smoke hood to operate in the working mode corresponding to the noise level, includes:

[0158] S310, obtain the third air fume concentration.

[0159] S320, determine whether the concentration of oil fume in the third air is greater than the preset oil fume concentration threshold.

[0160] If yes, repeat step S330 until the third air fume concentration is less than or equal to the preset fume concentration threshold; if no, execute steps S340-S360.

[0161] S330 controls the fan to run at the first current speed.

[0162] S340 controls the fan to operate in mode nine.

[0163] After obtaining the current noise parameters of the fan in the ninth mode, step S350 determines whether the current noise parameters are greater than the noise threshold. If yes, repeat steps S340-S350 until the noise is within acceptable limits; otherwise, proceed to step S360.

[0164] S360, confirm that the current noise level is within acceptable limits, and control the smoke hood to run at the second current speed.

[0165] In this embodiment, the ninth mode is to control the fan speed to decrease by 1%.

[0166] In step S330, if the concentration of the third air fume is greater than a preset fume concentration threshold (Y3 > Y0), the fan is controlled to run at the first current speed until the concentration of the third air fume is less than or equal to the preset fume concentration threshold. During this process, the fan is still controlled to run at a relatively high speed to quickly reduce the concentration of the third air fume until Y3 ≤ Y0. In this embodiment, the concentration of the third air fume is periodically detected. For example, after controlling the fan to run at the first current speed for 3 minutes, the concentration of the third air fume is checked to see if it is less than or equal to Y0. If not, the fan is controlled to run at the first current speed for another 3 minutes, and the concentration of the third air fume is checked to see if it is less than or equal to Y0. This step is repeated until Y3 ≤ Y0.

[0167] When Y3≤Y0, the fan speed is reduced by 1%, the current noise parameter is obtained, and if the current noise parameter is less than the noise threshold, the current noise level is determined to be acceptable, and the fan is controlled to run at the second current speed. The second current speed is less than the first current speed.

[0168] In summary, when the noise level is Level 1, the comparison between the obtained third air fume concentration Y3 and the fume concentration threshold Y0 is first determined. Then, different working modes are selected to control the fan based on the comparison between Y3 and Y0 until the noise level is within acceptable limits. Finally, the fan is controlled to maintain the speed at which the noise level is within acceptable limits.

[0169] Based on the above examples, it can be seen that in this application, when the noise level is unqualified, the noise level is determined by comparing the noise characteristic value with a preset threshold. In cases where the noise level is level two or three, the noise level is first reduced, and then the smoke machine is controlled to operate in the mode corresponding to the lower noise level. This gradually alleviates and eliminates the noise, allowing for targeted treatment of different noise conditions and improving the stability of the system through step-by-step noise reduction.

[0170] Secondly, this application provides a noise control device applied to a controller within a smoke machine control system; combined with Figure 4 As shown, the device includes: an acquisition module 10, a judgment module 20, a first determination module 30, a calculation module 40, a second determination module 50, and a control module 60.

[0174] The calculation module 40 is used to calculate noise characteristic values ​​based on noise parameters and noise thresholds.

[0175] The second determining module 50 is used to determine the noise level based on the comparison relationship between the noise characteristic value and the preset threshold.

[0176] The control module 60 is used to control the smoke hood to operate in a working mode corresponding to the noise level.
