[0002] With the development of smart home and kitchen appliance technologies, users are paying more attention to the safety, energy efficiency, and intelligence level of cooktops. Traditional cooktops typically rely on physical sensors such as thermocouples and flame ionization sensors to achieve ignition detection and flameout protection. However, these methods have certain drawbacks. For example, current technologies focus on detecting the presence of a flame, lacking effective real-time monitoring and diagnostic capabilities for combustion process stability, combustion efficiency, and fault detection; contact sensors are exposed to harsh environments of high temperature, high humidity, and oil fumes for extended periods, making them prone to aging, carbon buildup, or damage, leading to decreased detection sensitivity and false alarms, requiring regular maintenance or replacement, increasing usage costs and maintenance burden; traditional cooktops typically only perform a simple gas supply cut-off operation after a malfunction, lacking intelligence, resulting in a poor user experience.

[0023] This application's method for troubleshooting cooktop malfunctions is primarily applied to kitchen appliances. Specifically, it can be applied to range hoods and cooktops. Range hoods are electrical devices in the kitchen used to extract fumes, odors, and high-temperature steam generated during cooking, effectively improving kitchen air quality and protecting health. Range hood types can include top-mounted, side-mounted, and downdraft types, etc., and this application does not limit this. Cooktops are the core cooking equipment in the kitchen, used for open-flame heating. Types of cooktops include gas cooktops and integrated cooktops; the cooktop in this application preferably uses gas for combustion.

[0024] Figure 1 This is a flowchart illustrating a stove malfunction handling method according to an exemplary embodiment.

[0025] In step S101, the sound information corresponding to the combustion chamber of the stove in the cooking state is obtained, and the acoustic modal frequency corresponding to the combustion chamber is extracted from the sound information.

[0026] In the embodiments of this specification, the cooking state may refer to the state in which the stove is being used for heating or cooking operations.

[0027] The combustion chamber can refer to the space or area within a stove, such as a gas stove, where fuel mixes with air and undergoes combustion. For example, it typically refers to the area below or inside the burner head.

[0028] Sound information can refer to the sound wave signals generated in the combustion chamber during the combustion process. Sound information is the sound wave signals from the combustion chamber area of ​​the stove collected by sound sensors, such as microphones.

[0029] Acoustic modal frequencies refer to specific frequency components generated within the combustion chamber due to gas vibration or resonance, and are directly related to combustion stability. The acoustic modal frequencies are determined by the shape, size, boundary conditions, and internal medium of the combustion chamber, such as the fuel gas, air, and the physical properties of the combustion products, such as temperature, density, and sound velocity.

[0030] Figure 2 This is a structural diagram of a stove according to an exemplary embodiment. For example... Figure 2 As shown, the device includes a cookware, a burner, and sound sensors. The combustion chamber is located below the cookware, and multiple sound sensors, such as electret condenser microphones, microelectromechanical system (MEMS) microphones, piezoelectric microphones, and fiber optic microphones, are positioned near the combustion chamber. This application does not limit the type or number of sound sensors. Preferably, this application may evenly arrange four MEMS microphones near the combustion chamber.

[0031] In response to cooking commands, such as a user igniting the stove, the sound sensor acquires the stove's sound information corresponding to the combustion chamber when the stove is in cooking mode. This sound information may contain noise impurities, such as the noise from a spatula stirring or the noise from a range hood; this application does not limit the scope of the noise. The stove's sound information can be filtered, for example, using bandpass filtering or notch filtering, to remove impurities and obtain the final sound information. Alternatively, the stove's sound information can be enhanced and separated, for example, by using spectral subtraction or adaptive filtering to separate the noise from the sound information corresponding to the combustion chamber. This application does not limit the noise reduction filtering method for the stove's sound information.

[0032] After the sound information is determined, the acoustic modal frequencies corresponding to the combustion chamber are extracted from the sound information.

[0033] In step S103, the acoustic modal frequencies are subjected to spectral analysis to obtain target frequency offset information and target harmonic distortion information.

[0034] In the embodiments of this specification, the target frequency offset information may refer to the deviation between the currently detected acoustic modal frequency and the standard modal frequency or the preset normal frequency.

[0035] Target harmonic distortion information can refer to harmonic components, such as the degree of distortion of the second and third harmonics relative to the fundamental frequency. For example, incomplete combustion may lead to harmonic anomalies.

[0036] Figure 3 This is a flowchart illustrating a fault handling procedure according to an exemplary embodiment. Figure 3 As shown, spectral analysis is performed on the acoustic modal frequencies to determine the frequency peaks and multiple acoustic frequencies within a preset frequency band; a weighted average is performed on the multiple acoustic frequencies within the preset frequency band to obtain the average frequency; and the target frequency offset information is determined based on the multiple acoustic frequencies and the average frequency.

[0037] In the embodiments of this specification, the frequency peak value in the acoustic modal frequency is... These are prominent frequency points on the spectrum that are higher than surrounding frequencies, used to reflect the main resonant or combustion characteristic frequencies of the combustion chamber. The preset frequency band can refer to a band that includes the frequency peak. For example, the frequency peak... A frequency of 100 Hz corresponds to an amplitude of 20 dB. The peak frequency can be selected. The amplitude of 10 dB to the left and right is the preset frequency band, i.e., the amplitude of 10 dB to 30 dB, which is not limited in this application. The average frequency is the frequency obtained by weighted averaging of all acoustic frequencies within the preset frequency band.

[0038] For example, the formula corresponding to the target frequency offset information is: .

[0039] in, This can be represented as target frequency offset information. N is the number of acoustic frequencies within the preset frequency band. It can represent the i-th acoustic frequency. This can be expressed as the average frequency. The formula for determining the average frequency is: = . It can be represented as the weight value corresponding to the i-th acoustic frequency, but this application does not limit it.

[0040] After determining multiple acoustic frequencies and the average frequency from the acoustic modal frequencies, the target frequency offset information corresponding to the current moment is determined based on the multiple acoustic frequencies and the average frequency.

[0041] In one possible implementation, the acoustic modal frequencies are subjected to spectral analysis to obtain the target fundamental frequency; the second harmonic amplitude and the third harmonic amplitude corresponding to the target fundamental frequency are determined; and the ratio of the third harmonic amplitude and the second harmonic amplitude is calculated to determine the target harmonic distortion information.

[0042] In the embodiments of this specification, the target fundamental frequency can refer to the frequency corresponding to the largest amplitude point of the acoustic modal frequencies. The second harmonic amplitude is the component with a frequency twice that of the target fundamental frequency. The third harmonic amplitude is the component with a frequency three times that of the target fundamental frequency.

[0043] For example, the fast Fourier transform of acoustic modal frequencies yields the following formula:

[0044] Furthermore, the complex spectrum is output. The formula for calculating amplitude is as follows: Furthermore, the target baseband frequency Furthermore, based on the target fundamental frequency, the second harmonic amplitude is determined. Third harmonic amplitude Based on the second and third harmonic amplitudes, the target harmonic distortion information is determined. The target harmonic distortion information (HDR) is the ratio between the third harmonic amplitude and the second harmonic amplitude.

[0045] In step S105, the stove status information is determined based on the target frequency offset information and the target harmonic distortion information.

[0046] In the embodiments of this specification, the stove status information can refer to the operating status of the stove during the cooking process. For example, the stove status information may include abnormal status information and normal operating status information. Abnormal status information includes blockage abnormal status information and gas leakage abnormal status information.

[0047] In one possible implementation, blockage abnormality information is determined when the target frequency offset information is greater than a preset frequency offset threshold and the target harmonic distortion information is less than a preset harmonic distortion threshold; or leakage abnormality information is determined when the target frequency offset information is less than a preset frequency offset threshold and the target harmonic distortion information is greater than a preset harmonic distortion threshold.

[0048] In the embodiments of this specification, the blockage abnormality information can indicate relevant information about the burner being blocked. For example, partial blockage of the combustion nozzle, carbon buildup blocking the burner cap orifice, etc.

[0049] Gas leak abnormality information can indicate information related to gas pipeline leaks or leaks at the connection between the gas pipeline and the burner.

[0050] For example, in the target frequency offset information Greater than the preset frequency offset threshold And target harmonic distortion information Less than the preset harmonic distortion threshold In this case, the stove status information is determined to be in an abnormal state. Specifically, the acoustic modal frequency has undergone a significant positive shift, but the waveform of the combustion sound wave is in a stable state. At this time, the stove status information is confirmed to be in a blocked abnormal state, that is, burner blockage will restrict the gas flow, resulting in a decrease in the flow rate of the actual combustion gas-air mixture or a change in the mixing ratio.

[0051] Target frequency offset information Less than the preset frequency offset threshold And target harmonic distortion information Greater than the preset harmonic distortion threshold In the case where the measured acoustic modal frequency of the combustion chamber does not change much compared to the standard modal frequency under normal conditions, but the combustion sound wave contains significantly enhanced harmonic components and the waveform becomes irregular and disordered, it indicates that there is strong nonlinearity or instability in the combustion process. At this time, the stove status information is determined to be gas leakage abnormal status information.

[0052] In another possible implementation, the target frequency offset information Greater than the preset frequency offset threshold And target harmonic distortion information Greater than the preset harmonic distortion threshold In the case where the acoustic modal frequency has shifted significantly and the harmonic distortion of the combustion sound wave has also increased significantly, the abnormal status information of the stove can be severe backfire, severe flame lift-off or blow-out, violent combustion oscillation, etc.

[0053] In one possible implementation, the target frequency offset information Less than the preset frequency offset threshold And target harmonic distortion information Less than the preset harmonic distortion threshold In the case where the acoustic modal frequency of the combustion chamber at the current moment changes very little compared to the standard modal frequency, and the harmonic components of the sound waves generated by combustion are very weak and the total harmonic distortion is low, the stove status information is determined to be in normal operation, that is, the stove can be used normally.

[0054] In step S107, when the stove status information indicates that the stove is in an abnormal state, stove fault information is generated.

[0055] In the embodiments of this specification, stove malfunction information may refer to information describing the stove's abnormality when the stove is in an abnormal state.

[0056] In one possible implementation, the stove status information includes blockage abnormality status information corresponding to the blockage abnormality status and gas leakage abnormality status information corresponding to the gas leakage abnormality status; when the blockage abnormality status information indicates that the stove is in a blockage abnormality status, blockage fault information corresponding to the blockage abnormality status is generated; or when the gas leakage abnormality status information indicates that the stove is in a gas leakage abnormality status, gas leakage fault information corresponding to the gas leakage abnormality status is generated.

[0057] In the embodiments of this specification, blockage fault information can be represented as specific fault information generated after the blockage abnormality status information is confirmed, that is, after the system determines that the stove is indeed in a blockage abnormality state, such as a fault report, including fault description information, fault level, etc., which is not limited in this application. Gas leakage fault information can be represented as fault information generated after the gas leakage abnormality status information is confirmed.

[0058] For example, when the detected abnormal status information of the stove is a blockage abnormality, indicating that the stove is in a blockage abnormality state, corresponding blockage fault information is generated for the stove, which may include the cause of the burner blockage, the fault level, and the fault handling method. When the detected abnormal status information of the stove is a gas leakage abnormality, indicating that the stove is in a gas leakage abnormality state, corresponding gas leakage fault information is generated for the stove, which may include the cause of the gas leakage, the degree of danger of the gas leakage, and the fault handling method.

[0059] In step S109, the stove is processed according to the fault handling method corresponding to the stove fault information.

[0060] In the embodiments of this specification, the fault handling method can refer to the method of handling the abnormal state of the stove.

[0061] In one possible implementation, a blockage alarm is triggered and the burner's flame is adjusted to a preset flame based on the blockage fault handling method corresponding to the blockage fault information; or a leak alarm is triggered and the gas valve of the stove is shut off based on the gas leak fault handling method corresponding to the gas leak fault information.

[0062] For example, if the stove malfunction information is determined to be a blockage fault, the corresponding blockage fault handling method is retrieved from the stove malfunction handling system. Then, based on the gas leak handling method, the blockage fault is addressed, i.e., an abnormality is displayed on the range hood's visual panel, such as "Stove burner malfunction, please check for blockage," though this application is not limited to this. An alarm can be used, such as a short, non-emergency sound. Simultaneously, the stove malfunction handling system automatically adjusts the burner's power to a preset level, i.e., adjusts the power level to a safe level, for example, reducing it from 5kW to 2kW, this application is not limited to this either. This ensures complete combustion of the gas and avoids incomplete combustion that produces carbon monoxide, threatening user safety.

[0063] If the stove malfunction is determined to be a gas leak, the corresponding gas leak handling method is retrieved from the stove malfunction handling system. The gas leak is then handled according to this method, i.e., an immediate leak alarm is triggered, for example, a buzzer sounds continuously, and a red warning flashes on the range hood's visual panel displaying "Gas Leak, Ventilate Immediately" (this application is not limited to this). Simultaneously, the stove malfunction handling system immediately cuts off the gas supply via a solenoid valve to physically isolate the gas source. The system then immediately sends the gas leak information to the cloud, i.e., the stove manufacturer, who then dispatches professional personnel for repair.

[0064] In one possible implementation, the target gas flow rate is determined when the stove is in normal operating condition; the range hood airflow is then adjusted based on the target gas flow rate.

[0065] For example, a Fast Fourier Transform is performed on the sound information to extract the peak frequencies of the first three orders of acoustic modal frequencies, i.e., the first-order peak frequencies. Second-order peak frequency Third-order peak frequency Therefore, the frequency offset is calculated as follows: . This can be expressed as the reference frequency at ignition. Furthermore, the target gas flow rate Q is determined. Where a and b are preset gas flow coefficients, and this application does not limit the specific values ​​of a and b.

[0066] Upon receiving the target gas flow rate, the stove fault handling system immediately adjusts the range hood's airflow in real time to improve its smoke extraction efficiency. For example, if the target gas flow rate increases from 1.2 m³ / h to 2.5 m³ / h, the system immediately increases the range hood's airflow from 8 m³ / min to 18 m³ / min, i.e., from medium to high speed. This application does not limit this adjustment.

[0067] In one possible implementation, when the user turns off the stove (i.e., when the user is not using the stove), fault monitoring stops, and the system resumes monitoring when the user uses the stove again for cooking. After the stove fault handling is completed, the system records and saves the handling process.

Figure 4 The stove malfunction handling system may include: The acquisition module 401 is used to acquire the sound information corresponding to the combustion chamber of the stove in the cooking state, and extract the acoustic modal frequency corresponding to the combustion chamber from the sound information.

[0069] The spectrum analysis module 403 is used to perform spectrum analysis on the acoustic modal frequencies to obtain target frequency offset information and target harmonic distortion information.

[0070] In one possible implementation, the spectrum analysis module 403 includes: The frequency peak determination unit is used to perform spectral analysis processing on the acoustic modal frequencies to determine the frequency peaks in the acoustic modal frequencies and multiple acoustic frequencies within a preset frequency band; the multiple acoustic frequencies include the frequency peaks. The average frequency determination unit is used to perform weighted averaging on the multiple acoustic frequencies within the preset frequency band to obtain the average frequency. The offset information determination unit is used to determine the target frequency offset information based on the plurality of acoustic frequencies and the average frequency.

[0071] In one possible implementation, the spectrum analysis module 403 further includes: The target fundamental frequency determination unit is used to perform spectral analysis processing on the acoustic modal frequencies to obtain the target fundamental frequency; The harmonic amplitude determination unit is used to determine the second harmonic amplitude and the third harmonic amplitude corresponding to the target fundamental frequency; The distortion information calculation unit is used to perform ratio calculation on the third harmonic amplitude and the second harmonic amplitude to determine the target harmonic distortion information.

[0072] The stove status information determination module 405 is used to determine the stove status information based on the target frequency offset information and the target harmonic distortion information.

[0073] In one possible implementation, the stove status information determination module 405 includes: A congestion anomaly status information determination unit is used to determine the congestion anomaly status information when the target frequency offset information is greater than a preset frequency offset threshold and the target harmonic distortion information is less than a preset harmonic distortion threshold; or The air leakage abnormality information determination unit is used to determine the air leakage abnormality information when the target frequency offset information is less than the preset frequency offset threshold and the target harmonic distortion information is greater than the preset harmonic distortion threshold.

[0074] In one possible implementation, the stove status information determination module 405 further includes: The target gas flow rate determination unit is used to determine the target gas flow rate when the target frequency offset information is less than a preset frequency offset threshold and the target harmonic distortion information is less than a preset harmonic distortion threshold. The range hood fan speed adjustment unit is used to adjust the air volume of the range hood according to the target gas flow rate.

[0075] The stove fault information generation module 407 is used to generate stove fault information when the stove status information indicates that the stove is in an abnormal state.

[0076] In one possible implementation, the stove malfunction information generation module 407 includes: A blockage fault information generation unit is used to generate blockage fault information corresponding to the blockage abnormality state when the blockage abnormality state information indicates that the stove is in the blockage abnormality state; or The gas leakage fault information generation unit is used to generate gas leakage fault information corresponding to the gas leakage abnormality state when the gas leakage abnormality state information indicates that the stove is in the gas leakage abnormality state.

[0077] The fault handling module 409 is used to handle the fault of the stove according to the fault handling method corresponding to the fault information of the stove.

[0078] In one possible implementation, the fault handling module 409 includes: The blockage handling unit is used to issue a blockage alarm and adjust the flame of the stove burner to a preset flame based on the blockage fault handling method corresponding to the blockage fault information; or The gas leak handling unit is used to issue a leak alarm and shut off the gas valve of the stove according to the gas leak fault handling method corresponding to the gas leak fault information.
