With the improvement of people's living standards, the requirements for kitchen environment are getting higher and higher. The performance and intelligence of range hood have become important indicators to measure its quality.

[0003] Traditional range hoods usually adopt a single smoke extraction chamber design, which has certain limitations in terms of smoke extraction efficiency and energy consumption.

[0059] It should be noted that the order of description of the following embodiments is not intended to limit the priority order of the embodiments.

[0060] The present application provides a range hood control method, comprising: in response to a start-up operation for the range hood, identifying the working state of a stove; determining a target smoking chamber of the range hood based on the working state of the stove; after starting the target smoking chamber, monitoring a cooking area to identify current environmental information and cooking state information of the cooking area; generating target working parameters of the target smoking chamber based on the environmental information and the cooking state information; and updating current working parameters of the target smoking chamber based on the target working parameters to exhaust fumes generated in the cooking area.

[0061] See also Figure 2 , Figure 2 The flow chart of the range hood control method provided in the embodiment of the present application is as follows. The range hood control method provided in the embodiment can be executed on a range hood, which includes a plurality of separate smoking chambers, and the range hood is linked with a corresponding stove. The range hood control method can specifically include the following steps:

[0062] S1. In response to the start-up operation of the range hood, identifying the working status of the cooker;

[0063] Specifically, in step S1, when the user starts the range hood, the working status of the stove is first identified, including the switch status of the stove, the fire power, whether the gas valve is open, and so on.

[0064] S2. Determine the target smoking chamber of the range hood based on the working status of the cooker;

[0065] Specifically, for step S2, based on the working state of the cooker, the smoking chamber to be activated is automatically determined. For example, if only one side of the cooker is working, only the smoking chamber on the corresponding side will be activated to improve efficiency and reduce energy consumption.

[0066] S3. After starting the target smoking chamber, monitor the cooking area and identify the current environment information and cooking status information of the cooking area;

[0067] Specifically, for step S3, after the target smoking chamber is started, the cooking area continues to be monitored, and environmental data and cooking data, including smoke size, temperature, sound, etc., are acquired in real time through integrated sensors.

[0068] S4. Generate target operating parameters of the target smoking chamber based on environmental information and cooking status information;

[0069] Specifically, for step S4, the acquired data is preprocessed and analyzed to identify the current environmental information of the cooking area (such as smoke size and temperature changes) and cooking status information (such as cooking method and food type), and generate the working parameters of the target smoking chamber based on the monitored environmental information and cooking status information, including the lifting height, air volume, smoking frequency, smoking amount and smoking range of the smoking chamber.

[0070] S5. Update the current operating parameters of the target smoking chamber based on the target operating parameters to exhaust the fumes generated in the cooking area;

[0071] Specifically, for step S5, the current working parameters of the range hood are updated according to the generated target working parameters to ensure that the range hood can effectively exhaust the fumes generated in the cooking area, and adjust the working state of the smoking chamber in real time according to the monitored environmental changes and cooking status to adapt to different cooking needs.

[0072] It can be seen that the range hood control method provided in this embodiment reduces the need for users to manually adjust the range hood by automatically controlling the range hood, allowing users to focus more on the cooking process. The automated control also ensures that the range hood is automatically started and adjusted when needed, thereby improving efficiency. Unnecessary energy waste is avoided by accurately controlling the working status of each smoking chamber. For example, the corresponding smoking chamber is only started when the stove is in use, thereby saving energy; the smoking parameters are intelligently adjusted according to the actual cooking environment and status, so that the range hood can adapt to different cooking needs, whether it is cooking, steaming or frying, it can provide a suitable smoking effect. It can realize intelligent linkage with the stove and automatically open the smoking chamber in the corresponding area, further improving the user experience and ensuring the air quality in the cooking area.

[0073] Furthermore, in some embodiments, step S3 of “monitoring the cooking area and identifying the current environment information and cooking status information of the cooking area” may specifically include:

[0074] S31. The cooking area is monitored in real time through the sensor integrated in the range hood to obtain the corresponding environmental data and cooking data;

[0075] S32. Preprocessing the environmental data and cooking data;

[0076] S33. Identify the preprocessed environmental data to obtain environmental information corresponding to the cooking area;

[0077] S34. Determine the cooking status information corresponding to the cooking area based on the pre-processed environmental data.

[0078] Specifically, for step S3, the cooking area is mainly monitored in real time by the sensor integrated in the range hood, so as to obtain the current environmental data and cooking data of the cooking area, including the concentration, temperature, sound and image in the cooking area of ​​the smoke; the obtained environmental data and cooking data are preprocessed for subsequent identification and analysis, and the preprocessing may include steps such as data cleaning, denoising and normalization. The acquisition of environmental information includes image recognition and target detection on the preprocessed environmental data, for example, image recognition on the preprocessed environmental data is performed to determine the smoke information of the cooking area, including the concentration, distribution and change trend of the smoke; target detection is performed on the preprocessed environmental data to determine the height information of the cooking tools (such as pots) corresponding to the activated stove in the cooking area, and the location information of the cooking user; the acquisition of cooking status information includes audio recognition, cooking status recognition and user body status recognition on the environmental data, and the cooking status information such as cooking, steaming, frying, etc. is determined based on the recognized cooking audio signal; the current body status information of the cooking object is determined based on the recognized human voice signal, such as whether coughing, so as to determine whether the amount of smoking needs to be adjusted.

[0079] This embodiment can accurately obtain the environmental data of the cooking area through real-time monitoring and preprocessing, providing accurate input for subsequent intelligent control; through image recognition and target detection, it can timely identify the concentration and distribution of smoke, as well as the location of cooking tools and ingredients, so as to manage smoke more effectively; through audio recognition and signal analysis, it can intelligently identify the cooking status and the physical state of the cooking object, providing a basis for the intelligent adjustment of the range hood. Based on the identified environmental information and cooking status information, the working parameters of the smoking chamber, such as lifting height, air volume, smoking frequency, etc., can be adjusted in a personalized manner to meet different cooking needs.

[0080] Further, in some embodiments, step S33 of “identifying the pre-processed environmental data to obtain environmental information corresponding to the cooking area” may specifically include:

[0081] S331. Perform image recognition on the preprocessed environmental data to determine the smoke information corresponding to the cooking area;

[0082] S332. Perform target detection on the preprocessed environmental data to determine the height information of the cooking tools corresponding to the activated stove in the cooking area, and determine the position information of the cooking objects in the cooking area.

[0083] Specifically, for step S33, after obtaining the pre-processed environmental data, first use image recognition technology to monitor and analyze the smoke in the cooking area in real time. For example, the concentration, distribution and change trend of the smoke, as well as the starting point and diffusion path of the smoke are identified through image recognition algorithms. Then, the target detection technology is used to identify the height information of the cooking tools (such as pots) corresponding to the activated stoves in the cooking area. At the same time, the position information of the cooking objects (such as ingredients) in the cooking area can also be determined, including the distribution and movement of the ingredients. In addition, the height information and position information of the current cooking user in the cooking area can also be identified through target detection technology, so as to automatically adjust the lifting height of the smoking chamber according to the height information and position information of the cooking user. For example, the wind cavity near the user's position is reduced to the minimum, and the hidden cavity is opened to increase the smoking range.

[0084] This embodiment can monitor the smoke situation in the cooking area in real time through image recognition technology, including the concentration, distribution and change trend of the smoke, which helps to adjust the working parameters of the smoking chamber in time to more effectively discharge the oil smoke and reduce the potential impact of the oil smoke on the health of users. Through the target detection technology, the height information of the cooking tools is identified, so as to intelligently adjust the lifting height of the smoking chamber. For example, when the cooking tools are high, the lifting height of the smoking chamber can be automatically adjusted to be closer to the oil smoke source and improve the smoking efficiency. By identifying the location information of the cooking object, the oil smoke generation area can be more accurately judged, so as to adjust the working parameters of the smoking chamber in a targeted manner. For example, when the ingredients are concentrated on one side of the cooking area, the smoking range of the smoking chamber can be automatically adjusted to concentrate the smoking force on the area where more oil smoke is generated. By intelligently adjusting the working parameters of the smoking chamber, the oil smoke can be more effectively discharged, the interference of oil smoke on the cooking process can be reduced, and the cooking efficiency can be improved. Through precise monitoring and intelligent adjustment, the manual operation of the user is reduced, providing a more convenient and comfortable cooking experience. By accurately controlling the working state of the smoking chamber, unnecessary energy waste can be avoided, and energy saving and environmental protection can be achieved. For example, the system can intelligently adjust the air volume and power of the smoking chamber according to the concentration and distribution of smoke, achieving the best smoking effect with the lowest energy consumption.

[0085] It can be seen that this embodiment realizes accurate monitoring and intelligent recognition of cooking area environment information through image recognition and target detection technology, which not only improves the smoke extraction efficiency and effect of the range hood, but also enhances the user's cooking experience, while achieving energy conservation and environmental protection, and helping to improve the quality of the kitchen environment and user health.

[0086] Further, in some embodiments, step S34 “determining cooking status information corresponding to the cooking area based on the pre-processed environmental data” includes:

[0087] S341. Perform audio recognition on the preprocessed environmental data to determine the cooking audio signal and the human voice signal in the cooking area;

[0088] S342. Determine cooking status information based on the cooking audio signal;

[0089] S343. Determine the current physical state information of the cooking object based on the human voice signal.

[0090] Specifically, for step S34, after obtaining the pre-processed environmental data, the cooking audio signal in the cooking area is monitored and analyzed in real time using the audio recognition technology integrated in the range hood, for example, the sound characteristics generated by different cooking activities, such as stir-frying, frying, steaming, etc., are identified to determine the current cooking state. Based on the identified cooking audio signal, the cooking state information can be determined, such as different cooking methods such as stir-frying, steaming, and frying. The cooking state can also be further refined by analyzing the frequency, intensity, and rhythm of the sound, such as judging the intensity of stir-frying or the oil temperature of frying.

[0091] At the same time, it can also identify human voice signals in the cooking area, such as the user's command voice or coughing sound. Based on the human voice signal, the current physical state information of the cooking object can be determined, such as whether it is necessary to increase the amount of smoke or adjust the working state of the smoking chamber due to coughing.

[0092] This embodiment uses audio recognition technology to accurately monitor and identify various cooking states, thereby providing more precise smoking control. According to the identified cooking state, the smoking frequency, smoking amount and smoking range of the smoking chamber can be intelligently adjusted to adapt to different cooking needs and improve smoking efficiency. By recognizing and responding to human voice signals, such as the user's command voice, a more intuitive and convenient user interaction method is provided. For example, the user can control the working state of the range hood through simple voice commands, such as turning on, off or adjusting the smoking intensity. By recognizing physical status information such as coughing sounds, the amount of smoking can be adjusted in time to reduce the potential impact of oil smoke on the user's health, especially in the case of long-term cooking. By monitoring abnormal sounds that may occur during the cooking process, such as excessive oil temperature or dry burning of pots, users are reminded in time to take measures to improve cooking safety.

[0093] Further, in some embodiments, step S4 "generating target working parameters of the target smoking chamber based on the environmental information and the cooking state information" may specifically include:

[0094] S41. Based on the environmental information, determine the lifting height and air volume of the target smoking chamber;

[0095] S42. Determine the smoking frequency, smoking amount and smoking range of the target smoking cavity based on the cooking status information.

[0096] Specifically, for step S4, this embodiment explains in detail how to generate the target working parameters of the target smoking chamber based on the environmental information and the cooking state information, and the specific steps include: firstly, analyzing the environmental information obtained from the sensor and the audio recognition, such as the concentration, temperature, distribution of the smoke, and the height and position information of the cooking tools. According to the above environmental information, the lifting height and air volume of the target smoking chamber are determined to ensure the smoking efficiency and coverage. Then, the cooking state information obtained from the audio recognition and the human voice signal is analyzed, such as the cooking method (cooking, steaming, frying, etc.) and the intensity of the cooking activity. According to the above cooking state information, the smoking frequency, smoking amount and smoking range of the target smoking chamber are determined to adapt to different cooking needs. Then, combining the environmental information and the cooking state information, the target working parameters of the target smoking chamber are generated, including the lifting height, air volume, smoking frequency, smoking amount and smoking range of the smoking chamber, to ensure that the range hood can effectively discharge the oil smoke. Finally, according to the generated target working parameters, the current working parameters of the target smoking chamber are updated, so that the range hood can adjust its working state in real time to adapt to the changes in the cooking environment.

[0097] In a specific embodiment, the sound signal below the smoking chamber can be identified, including the tone, timbre, or the changing frequency of the frequency waveform peak under the corresponding timbre, or the slope of the frequency peak; for example, when hot oil is added to cold dishes or dishes with water, a continuous sharp frequency sound will be generated, and the amount of smoking needs to be increased at this time; when steaming or after covering the pot, or a deep sound is generated, the amount of smoking can be reduced and the noise can be reduced by judging by the tone or timbre; when stir-frying, the spatula and the pot body will produce intermittent collision sounds, and the changing frequency of the sound frequency peak can be identified at this time to judge whether it is stir-frying, and the frequency needs to be increased when stir-frying, and the slope of the timbre frequency peak can be combined to judge the metal collision sound, or the wooden spatula and the metal collision sound. Or detect whether the user has a cough, if so, increase the speed of the smoking chamber, and open the smoking chambers on both sides.

[0098] This embodiment can generate accurate working parameters through precise monitoring of the environment and cooking status, realize precise control of the range hood, and adapt to different cooking environments and needs, whether it is cooking, steaming or frying, it can provide a suitable smoking effect. In addition, the user does not need to manually adjust the range hood, and the smoking parameters can be automatically adjusted according to the cooking situation, thereby improving the user experience, reducing unnecessary energy waste, and achieving energy saving and environmental protection.

[0099] Furthermore, in some embodiments, the range hood control method may further include:

[0100] Obtaining location information and physical status information of a cooking object in a cooking area;

[0101] Based on the position information and the body state information, determine the target working parameters of the target smoking chamber, and determine the newly activated smoking chambers and their corresponding required working parameters;

[0102] The current working parameters of the target smoking chamber are updated based on the target working parameters, so as to control the target smoking chamber to work according to the target working parameters, and control the newly started smoking chamber to work according to the required working parameters.

[0103] Specifically, the range hood control method in this embodiment also provides a method for adjusting the range hood based on the location information and physical state information of the cooking object (user). The specific process is as follows: Use sensors or other monitoring devices to obtain the location information and physical state information (such as whether coughing) of the cooking object (such as the user) in the cooking area. Based on the acquired location information and physical state information, determine the target working parameters of the target smoking chamber. For example, if the user is close to the range hood and a cough is detected, the amount of smoking and the wind speed can be increased. If multiple cooking areas are monitored to be used at the same time, the required newly activated smoking chamber and its corresponding working parameters will be determined to ensure that the oil smoke in all areas can be effectively handled. Alternatively, the wind cavity near the person's position is reduced to a minimum, and the newly activated smoking chamber is opened, which can be a hidden chamber in the range hood, to increase the smoking range. Update the current working parameters of the target smoking chamber based on the target working parameters to ensure that the range hood can work according to the target working parameters. At the same time, for the newly activated smoking chamber, it will also be controlled to work according to the required working parameters.

[0104] This embodiment can provide personalized smoking control according to the user's specific position and physical condition, improve smoking efficiency and reduce energy waste, so that users can enjoy more humane range hood control. The range hood can automatically adjust according to the user's actual needs to improve the comfort of the cooking process. By monitoring the user's position and physical condition, a stronger smoking effect can be provided when the user needs it, such as increasing the amount of smoke when coughing, which helps to protect the user's respiratory health. When multiple cooking areas are used at the same time, additional smoking chambers can be intelligently activated and adjusted to ensure that the oil smoke in the entire cooking area can be effectively controlled.

[0105] Furthermore, in some embodiments, the range hood control method may further include:

[0106] Acquire control voice and motion data of cooking objects in the cooking area;

[0107] Determine a voice control signal and a motion control signal of a cooking user based on the control voice and motion data, respectively;

[0108] The working state of the target smoking chamber is controlled based on the voice control signal and the action control signal.

[0109] Specifically, the present embodiment also provides a method for controlling the range hood by user voice or gesture sensing, which includes the following steps: using integrated voice recognition and motion capture technology to obtain the control voice and action data of the user in the cooking area. Based on the acquired control voice data, the user's voice control signal is identified and determined, such as "turn on the range hood", "increase the air volume" and other instructions. At the same time, the captured action data is analyzed to determine the user's action control signal, such as a waving action to turn on or off the range hood. According to the recognized voice control signal and action control signal, the working state of the target smoking chamber is automatically controlled. For example, if the user says "increase the air volume", the wind speed of the smoking chamber can be automatically increased; if the user waves, the lifting height or air volume of the smoking chamber can be adjusted according to the direction and speed of the waving.

[0110] This embodiment allows users to control the range hood through natural voice commands and intuitive body movements, providing a more natural and convenient interaction method; users can control the range hood without touching the range hood control panel during cooking, reducing the spread of grease and food residue on their hands, improving cooking convenience, and being able to respond to user voice and motion commands in real time, quickly adjust the working state of the range hood, and improve response speed and efficiency. In high temperature or dangerous environments, users do not need to directly touch the range hood, reducing safety risks during cooking.

[0111] In some embodiments, the range hood control method provided in this embodiment can be executed on a range hood, which is composed of multiple split-type smoking chambers, and each smoking chamber can be controlled separately. The range hood can also be controlled in linkage with the stove, such as automatically opening a single-side smoking chamber when the left stove is turned on. The hidden smoking chamber can be automatically opened by a sensor to judge the size of the smoke, or controlled by gesture sensing, voice, etc. By accurately controlling the working state of each smoking chamber, unnecessary energy waste can be avoided and energy saving and environmental protection can be achieved. The power can also be adjusted according to actual needs to reduce the overall energy consumption of the stove. When the ignition is started or the gas valve is opened, the corresponding smoking chamber on one side is lifted and opened. In the specific control process, the lifting height and air volume of the smoking chamber are adjusted mainly by identifying environmental information, and the amount of smoking is intelligently adjusted and the noise is reduced according to environmental information such as sound signals, the position of people, and coughing. Identify different cooking states such as stir-frying and steaming, and intelligently adjust the frequency and amount of smoking; the use of the left and right pots can be automatically identified, and the lifting and opening can be automatically performed. If the left side is used, only the left side is lifted and opened. Identify the height of the pot and adjust the lifting distance adaptively. The hidden smoking chamber is opened and closed by sensing the size of smoke; when it is detected that the stove is ignited or the stove gas valve is opened, the smoking chamber on the corresponding side is raised and lowered to open.

[0112] Identifying environmental information to adjust the lifting height and air volume includes: identifying the sound signal below the smoking chamber, including the tone, timbre or the changing frequency of the frequency waveform peak under the corresponding timbre, or the slope of the frequency peak; identifying the position of the cooking user, reducing the wind chamber near the cooking user's position to the minimum, and opening the hidden chamber to increase the smoking range; detecting whether the cooking user has a cough, if there is an increase in the speed, the smoking chambers on both sides are all opened. For example: when hot oil is added to cold dishes or dishes with water, a continuous sharp frequency sound will be generated, and the amount of smoking needs to be increased at this time; when steaming or covering the pot, or a deep sound is generated, judging by the tone or timbre, the amount of smoking can be reduced and the noise can be reduced; when stir-frying, the spatula and the pot body will produce intermittent collision sounds, at this time, the changing frequency of the sound frequency peak is identified to judge whether it is stir-frying, and the frequency needs to be increased when stir-frying, and at the same time, the slope of the timbre frequency peak can be combined to judge the metal collision sound, or the wooden spatula and metal collision sound.

[0113] In summary, the range hood control method provided in this embodiment firstly identifies the working state of the stove in response to the start-up operation of the range hood; then, based on the working state of the stove, determines the target smoking chamber of the range hood; after starting the target smoking chamber, monitors the cooking area to identify the current environmental information and cooking state information of the cooking area; then, based on the environmental information and cooking state information, generates the target working parameters of the target smoking chamber; finally, based on the target working parameters, updates the current working parameters of the target smoking chamber to exhaust the oil smoke generated in the cooking area. It can be seen that the range hood control method provided in this embodiment can intelligently adjust the amount of smoke according to actual cooking needs and environmental changes by accurately controlling the working state of each smoking chamber, so that the range hood can exhaust oil smoke more effectively, improve smoking efficiency, avoid unnecessary energy waste, and achieve energy saving and environmental protection; and the user does not need to manually adjust the range hood, and can automatically adjust to different cooking methods and environments, thereby improving the intelligence of the range hood and thus improving the user experience.
