[0055] Some embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0056] Embodiment 1

[0057] The embodiment of the present invention provides a range hood control method, see Figure 1 The flowchart of a range hood control method provided by an embodiment of the present invention is shown, and the method includes:

[0058] Step S102, responding to the instruction to turn on the range hood, obtaining the start time and cooking temperature.

[0059] Specifically, when the user needs to use the range hood, a start command will be issued. This command may be initiated through physical buttons, touch screen operations or voice commands, or it may be generated based on the control signal of the linked cooker. Once this command is received, the control unit (MCU) of the range hood will be activated immediately. At this stage, the current startup timestamp is first recorded, which is usually provided by the built-in real-time clock module to provide accurate time information. At the same time, the temperature sensing module starts working, which detects the temperature of the current kitchen environment, especially the temperature of the cooking area, through sensors installed inside or near the range hood.

[0060] Step S104, searching a preset gear output relationship table for a target working gear corresponding to the start time and the cooking temperature.

[0061] Specifically, the MCU will use the previously collected startup time and cooking temperature data to query the built-in gear output relationship table. This table is a pre-set data structure that contains the mapping relationship between different time periods and temperature ranges and range hood gears. This relationship may be based on historical data analysis or the manufacturer's default settings. For example, if it is detected that it is 8 o'clock in the morning and the temperature is 50°C, "weak gear" is selected as the initial working gear based on the learned user habits or the manufacturer's preset standards. This decision-making process is completed automatically without user intervention and aims to provide an optimal suction that matches the current cooking conditions.

[0062] Furthermore, the gear output relationship table includes: multiple working time periods; each working time period corresponds to multiple temperature intervals; and the temperature intervals correspond to working gears one by one. In some preferred embodiments of the present invention, the step of searching the preset gear output relationship table for the target working gear corresponding to the start-up time and the cooking temperature includes: determining the target working time period of the range hood corresponding to the start-up time in multiple working time periods; determining the target temperature interval of the range hood corresponding to the cooking temperature in the temperature interval corresponding to the target working time period; determining the working gear of the range hood corresponding to the target temperature interval, and determining the working gear as the target working gear.

[0063] Specifically, working time periods are usually divided according to the user's cooking habits or dining habits in a specific cultural context. For example, the preparation time for breakfast, lunch, and dinner may be defined as different working time periods. This division can be more refined, such as 6-8 am, 11-1 pm, 6-8 pm, etc., to adapt to the cooking schedules of different families. In each working time period, users may perform different types of cooking activities, resulting in different cooking temperature requirements. For example, frying eggs may only require medium temperature, while stir-frying vegetables may require higher temperature. Therefore, each time period will correspond to multiple temperature intervals to more accurately match the appropriate range hood gear. In the gear output relationship table, each temperature interval is directly associated with a specific working gear. This correspondence is set based on the direct proportional relationship between the range hood suction demand and the cooking temperature. For example, a lower temperature interval may correspond to a "weak" gear, while a higher temperature interval corresponds to a "strong" or "stir-fry" gear.

[0064] When the user starts the range hood, the current start-up time is first identified and compared with multiple working time periods in the gear output relationship table to determine which target working time period the moment belongs to. Next, the current cooking temperature is detected and the corresponding temperature range is found within the determined target working time period. This temperature range is determined based on the actual cooking temperature detected. Finally, based on the target temperature range determined in the previous step, the corresponding working gear is found in the gear output relationship table. This gear is determined based on the one-to-one correspondence between the preset temperature range and the working gear. The range hood can automatically select the working gear that best suits the current cooking conditions, thereby achieving an intelligent and efficient cooking environment.

[0065] Step S106, controlling the range hood to start running based on the target working gear.

[0066] Specifically, after determining the target working gear, the MCU will send a corresponding control signal to the motor drive module of the range hood, so that it adjusts to the selected gear and starts running. In this process, the speed of the motor will be adjusted according to the requirements of the selected gear, thereby changing the amount of suction. For example, if the "strong gear" is selected, the motor will run at a higher speed and generate stronger suction to cope with a large amount of oil smoke; if the "weak gear" is selected, the motor will run at a lower speed, saving energy while providing moderate suction. Ensure that the range hood can operate in a way that best suits the current cooking conditions.

[0067] Step S108, recording the working status of the range hood; wherein the working status includes: real-time cooking temperature, continuous operation time at the same working gear, and switching records of the working gear.

[0068] Specifically, during the entire cooking process, the MCU continuously monitors and records the working status of the range hood. This includes but is not limited to real-time monitoring of changes in cooking temperature, tracking the continuous operating time at each gear, and recording any gear switching events. These data are critical for optimizing future gear selections. For example, if it is found that within a specific time period, although the "weak gear" was initially selected, the user frequently manually switches to the "strong gear", this behavior pattern may be learned and its initial gear selection may be automatically adjusted under similar conditions in the future. Furthermore, this data can also be used to generate user usage reports to help users understand their cooking habits, or provide feedback to manufacturers to improve product design.

[0069] Furthermore, in some preferred embodiments of the present invention, the step of recording the working status of the range hood includes: recording the duration that the cooking temperature falls within the target temperature range; and recording the switching records of the working gears of the range hood.

[0070] Specifically, when the range hood starts running, its built-in temperature sensor will continuously monitor the surrounding cooking temperature. These temperature data are analyzed in real time to determine whether they fall within the preset target temperature range. If the current temperature meets the target range, the timing starts and the duration of this state is recorded. This duration is an important indicator that can reflect the frequency and habits of users cooking within a specific temperature range. For example, if the user often cooks for a long time in a high temperature range, the gear selection can be automatically adjusted to better suit the user's cooking needs.

[0071] In addition to temperature-related data, the range hood's switching between different working gears is also recorded in detail. Every time the user or the range hood automatically adjusts the gear, the operation will be accurately recorded, including the specific time when the switch occurred, the original gear, the new gear, and the reason for the switch (such as manual switching by the user or automatic adjustment by the range hood). These data help analyze the user's usage habits, such as when and at what temperature they tend to change the suction strength. By accumulating this data over a long period of time, the range hood can learn and predict the user's behavior patterns, thereby providing more personalized and accurate gear setting recommendations in future use. The range hood can not only monitor and respond to the current cooking environment in real time, but also learn the user's habits from long-term data accumulation to further optimize the performance of the equipment and user experience.

[0072] Step S110, updating the gear output relationship table based on the working status.

[0073] Specifically, based on the working status data collected in step S108, the MCU will execute a series of algorithms to update the gear output relationship table. Analyze the user's usage habits, such as the preferred gear in a specific time period, the frequency of use of the gear at different temperatures, etc., and integrate this information into the gear output relationship table. Over time, the range hood will become smarter, able to more accurately predict user needs and provide more personalized services. This self-learning ability not only improves the user experience, but also helps to improve energy efficiency and equipment efficiency.

[0074] Furthermore, based on the operating gear duration recorded by the range hood, in some preferred embodiments of the present invention, the step of updating the gear output relationship table based on the working status includes: if the temperature range corresponding to the cooking temperature changes, determining the operating duration of the target working gear of the range hood corresponding to the target temperature range after the cooking temperature changes; if the operating duration is greater than the preset duration, updating the statistical number corresponding to the target temperature range after the cooking temperature changes; and updating the gear output relationship table based on the updated statistical number.

[0075] Specifically, when the temperature changes during cooking, causing the temperature range to change, the range hood will immediately detect and determine the new temperature range. Subsequently, the range hood will measure the actual operating time of the range hood in the new temperature range, that is, the length of time from the change in the temperature range to the next change or the end of cooking. This time is an important basis for evaluating whether the newly set gear meets the current cooking needs.

[0076] The range hood will compare the running time calculated in the previous step with a preset standard time. This standard time is a threshold preset based on experience and user habits, and is used to determine whether a certain gear is suitable for the current cooking temperature range. If the actual running time exceeds this preset time, it means that the current gear may not be the best choice, and the range hood will update the statistical number of different gears in the temperature range accordingly. Specifically, the more frequently a gear is used, the more its statistical number will increase, reflecting the user's preference and usage habits for that gear.

[0077] As the statistics are updated, the range hood will re-analyze the data to determine the gears most frequently used by users in each temperature range. This step involves a data analysis algorithm that may consider multiple factors such as operating time and frequency of use to comprehensively evaluate the most suitable working gear for each temperature range. Ultimately, these analysis results will be used to update the gear output relationship table. The updated table can more accurately reflect the user's cooking habits and gear preferences, thereby improving the working efficiency and user experience of the range hood.

[0078] Through this continuous cycle of monitoring, analysis and updating, the range hood's control system can continuously learn the user's cooking habits, automatically adjust and optimize the gear settings, and ensure the best fume extraction effect every time it is used.

[0079] Furthermore, the range hood can also update the gear output relationship table according to the user's manual gear switching. In some preferred embodiments of the present invention, the step of updating the gear output relationship table based on the working state also includes: responding to the instruction of manual gear switching, recording the running time of the switched working gear after manual switching; if the running time of the switched working gear is greater than the preset time, determining the target temperature range corresponding to the current cooking temperature, updating the statistical number corresponding to the target temperature range corresponding to the switched working gear after manual switching; and updating the gear output relationship table based on the updated statistical number.

[0080] Specifically, when the user feels that the current suction force does not meet the cooking needs and manually switches the gear, the range hood will respond to this operation immediately. From the moment the user manually switches the gear, the range hood starts recording the new gear operation time until the gear changes again or the cooking activity ends. This time is important data for analyzing user preferences and evaluating the suitability of gears.

[0081] If the user's operation time at the new gear exceeds the preset standard time of the range hood, it indicates that the user is highly satisfied with the gear and thinks it is more suitable for the current cooking conditions. At this time, the range hood will determine the target temperature range to which the current cooking temperature belongs, and update the statistical number of manual gear switching in the temperature range accordingly in the gear output relationship table. This statistical number reflects the user's preference for different gears under specific temperature conditions.

[0082] As the statistics are continuously updated, the data in the range hood will more comprehensively reflect the user's actual usage habits and gear preferences. By regularly analyzing these accumulated data, the range hood can adjust the gear output relationship table and automatically optimize the gear setting to match the user's cooking temperature range. This self-learning and adjustment mechanism ensures that the range hood can provide more personalized and efficient range hood extraction performance in future use.

[0083] Through the above steps, the control system of the range hood can not only learn the user's cooking habits, but also respond to the user's immediate operations in a timely manner, thereby providing a smarter and more user-friendly gear adjustment in actual use.

[0084] Furthermore, in some preferred embodiments of the present invention, the step of updating the gear output relationship table based on the updated statistical number includes: determining the statistical number of multiple working gears corresponding to the temperature range, and calculating the total statistical number; calculating the proportion of each working gear in the total statistical number; determining the working gear corresponding to the highest proportion as the target working gear corresponding to the temperature range.

[0085] Specifically, the smoke machine will first access the updated gear output relationship table and extract the statistical number of each working gear in each temperature range. These statistical numbers reflect the frequency of users using each gear under different temperature conditions. Then, the smoke machine will sum these statistical numbers and calculate the total statistical number of all working gears in each temperature range. This total value represents the total frequency of all gears being used in this temperature range.

[0086] After obtaining the statistics of each working gear and the total statistics, the range hood then calculates the proportion of each gear in the total statistics. This step is achieved by dividing the statistics of each gear by the total statistics of the temperature range. The resulting percentage value represents the relative frequency of each gear being selected and used within the temperature range, which is an important indicator for evaluating the user's preference for different gears.

[0087] After the proportion of all gears is calculated, the range hood will compare and find the working gear with the highest proportion. This gear is the gear most frequently used by users in the temperature range, so it can be regarded as the user's preferred choice. Finally, the range hood sets the working gear with the highest proportion as the target working gear for the temperature range and updates it to the gear output relationship table. In this way, when the range hood automatically adjusts the gear of the range hood under similar temperature conditions, it will give priority to the working gear that users use most frequently and are most satisfied with.

[0088] Through the above steps, the range hood uses statistical analysis and data-driven methods to continuously optimize the gear output relationship table to make it more in line with the user's actual usage habits and needs, thereby improving the user experience and the performance of the range hood.

[0089] Furthermore, in some preferred embodiments of the present invention, after responding to the instruction to turn on the range hood and obtaining the start time and cooking temperature, the method also includes: obtaining user identity information, and determining a preset gear output relationship table based on the identity information.

[0090] Specifically, when the user issues a command to turn on the range hood through a physical button, touch screen or voice command, the range hood will immediately start the process of identifying the user. This may involve voice recognition, facial recognition technology or account information logged in through a smart device. For example, if the user controls the range hood through a voice command, the range hood can analyze the sound characteristics to confirm the user's identity. If it is controlled through a smartphone application, the range hood can use the user profile stored in the phone to identify the user.

[0091] Once the user's identity is confirmed, the range hood will retrieve the corresponding gear output relationship table from the database based on the user's personal preferences and historical usage data. Each user can have their own unique gear settings, which are automatically learned and optimized based on their past cooking habits and preferences. For example, if a user tends to cook at a lower temperature, or prefers to use a specific wind speed gear during a specific time period, this information will be encoded into their personalized gear output relationship table.

[0092] Through the above steps, the range hood can provide more personalized services for different users in the home. This personalization is not limited to the initial gear selection, but also includes the ability to continuously learn and adjust the gear settings according to user habits, so as to ensure that each use can meet the user's personalized needs and improve the overall cooking experience.

[0093] The present invention provides a range hood control method, the method comprising: responding to an instruction to turn on the range hood, obtaining a start-up time and a cooking temperature; searching for a target working gear corresponding to the start-up time and the cooking temperature in a preset gear output relationship table; controlling the range hood to start and run based on the target working gear; recording the working status of the range hood; wherein the working status includes: real-time cooking temperature, continuous operation time at the same working gear and switching record of the working gear; updating the gear output relationship table based on the working status; when the range hood is started, quickly selecting the range hood working gear in the preset gear output relationship table according to the start-up time and the cooking temperature, and recording the working status of the range hood at the same time, and updating the gear output relationship table according to the working status, so that the working gear selected according to the gear output relationship table is more and more in line with the needs of users, thereby improving the user experience.

[0094] Embodiment 2

[0095] Based on the above embodiment, the present invention provides another range hood control method. Figure 2 The flowchart of another range hood control method provided by the embodiment of the present invention is shown in FIG. Figure 3 A flow chart of updating a working gear provided by an embodiment of the present invention is shown.

[0096] The MCU that controls the range hood is divided into multiple data storage areas according to time periods and temperature segments. Here, the frequency of use of the three gears of the range hood, namely, the weak gear, the strong gear, and the stir-fry gear, is recorded as Na, Nb, and Nc respectively. When cooking, start the range hood. The MCU also records the start-up time t at this time, and determines which time period the start-up time t is in. At the same time, the temperature sensing module of the range hood detects the temperature to determine which temperature segment the cooking temperature T belongs to. According to the data recorded in the MCU data storage area, the most commonly used gear for cooking at the current temperature is started (the default for the first start is the strong gear). The MCU detects the running time of the current gear. If the gear is manually switched in the middle, the timer is reset. When the current gear running time exceeds 1 minute, the number of times the current gear is used Nx is recorded in the storage area of ​​the current temperature segment (for example, if the range hood is started at 8 o'clock in the morning and the temperature is detected to be 80°C, and the cooking time using the weak gear is greater than 1 minute, then it is recorded to the 7-9 o'clock time period, and 50-100 o'clock. ℃ temperature segment Na=Na+1), and calculate the gear that meets the user's cooking habits through the data recorded in the storage area, calculate the proportion of weak gear Pa=Na / (Na+Nb+Nc), the proportion of strong gear Pa=Na / (Na+Nb+Nc), the proportion of stir-fry Pa=Na / (Na+Nb+Nc), and take the maximum value S=Max(Pa, Pb, Pc), and obtain the gear most commonly used by users in this period and this temperature range. If Na=20, Nb=10, Nc=100, then Pa=15.3%, Pb=7.6%, Pc=76.9%, that is, under this condition, users most often use the stir-fry gear. Therefore, when the range hood reaches this temperature in this time period, it should automatically switch to the stir-fry gear.

[0097] The embodiment of the present invention provides a range hood control method, which detects the temperature during cooking through a temperature sensing module and determines the current temperature segment, and the MCU records the current range hood gear usage and the current time period in a storage area. After multiple uses, the user's gear usage habits of using the stove under different temperature conditions in different time periods (such as breakfast, lunch, and dinner) are calculated. Therefore, when the range hood is used subsequently, a range hood gear switch that conforms to the user's usage habits can be performed according to the data records, thereby realizing a user's customized demand for automatic switching of the range hood gear during cooking, and effectively improving the cooking experience.
