[0052] The following detailed description of some embodiments of the present invention is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.
[0053] Example 1
[0054] This invention provides a fan control method applied to the controller of a range hood. (See also...) Figure 1 The flowchart shown in this embodiment of the invention provides a fan control method, which includes:
[0055] Step S102, Begin.
[0056] Specifically, the range hood is in a power-on standby state, waiting for the start-up command; or, the range hood is running at a stable speed, waiting for user commands or operating information sent by linked devices.
[0057] Step S104: Respond to the external input working gear switching command and obtain the working gear change range.
[0058] Specifically, in the range hood controller, when a user sends a command to switch operating levels via an external input device (such as buttons, a touchscreen, etc.), the controller receives and processes this command. First, the controller needs to identify the current operating level and the target operating level, and then calculate the range of variation between these two levels. This range of variation refers to the range of airflow variation. After obtaining this range of variation, the controller can determine the corresponding speed adjustment scheme according to a preset algorithm.
[0059] Commonly, during the switching on and off process of a range hood, the noise level changes significantly due to the rapid change in fan speed. After recognizing the on / off command, the range of gear changes is determined. For example, if the current gear is 0 when the hood is turned on, and the target working gear after turning on is 5, the range of change corresponds to the airflow change range of the 5 gears.
[0060] Step S106: Determine the noise variation range corresponding to the working gear change range.
[0061] Specifically, after determining the operating speed range, the controller needs to further analyze the corresponding noise variation range. The noise variation range refers to the range of noise intensity variation generated by the range hood throughout the entire speed adjustment process. This range can be obtained through experimental data or a pre-set model.
[0062] Furthermore, in some preferred embodiments of the present invention, the step of determining the noise variation range corresponding to the working gear change range includes: determining the current variation range corresponding to the working gear change range; and determining the noise variation range corresponding to the current variation range.
[0063] Specifically, when the operating speed changes, the first step is to determine the corresponding current demand range. Different speeds correspond to different motor operating currents; higher speeds typically require higher current to provide stronger airflow, while lower speeds require lower current. The current values for different speeds can be obtained through precise measurement or by consulting the equipment specifications. For example, if the speed is switched from low to high, the controller will monitor the motor's transition from a lower current consumption state to a higher current consumption state.
[0064] The current consumption of a motor is directly related to its noise level. Generally, increased current means increased motor speed, resulting in more noise. To determine the range of noise changes corresponding to current variations, experimental data or technical parameters provided by the motor manufacturer can be used. By comparing noise test results at different current levels, a correlation model between current and noise levels can be established. This model will help the controller predict noise changes within a specific range of current variations.
[0065] The controller can accurately determine the corresponding noise variation range based on changes in the operating speed. This process is crucial to ensuring that the range hood maintains an ideal noise level when switching between different speeds, and it also provides the necessary basis for subsequent speed adjustment strategies.
[0066] Step S108: Divide the noise variation range into multiple speed regulation intervals based on the preset noise segmentation value.
[0067] Specifically, to achieve more precise speed control, the controller needs to divide the noise variation range into multiple speed control intervals. These intervals can be divided according to preset noise segmentation values; for example, each interval represents a fixed noise intensity range. In this way, the controller can subdivide the entire speed control process into several stages, each stage corresponding to a specific noise intensity range and speed control requirements. Thus, the controller can adjust the fan speed according to the specific requirements of each stage, thereby achieving a smoother and more efficient speed control effect.
[0068] Specifically, the noise separation value can be set to different values based on the different noise sensitivities of different groups of people. In this embodiment, for people with a higher noise tolerance, the noise separation value can be set to a larger value; for people with a lower noise tolerance, the noise separation value can be set to a slightly smaller value. By finely dividing the noise variation range through the noise separation value, the operating status of the range hood can be adjusted as quickly as possible without affecting the user experience.
[0069] Furthermore, in some preferred embodiments of the present invention, after preliminary questionnaire surveys, the population is divided into three age groups: youth, middle-aged, and elderly, with noise sensitivity increasing sequentially, and the set range also changing sequentially. For example, the elderly are more sensitive to changes of more than 2dB, but middle-aged and young people may be more sensitive to changes of more than 3dB.
[0070] For example, if the noise variation range is 6dB, corresponding to the elderly population, the noise variation range is divided into 3 speed adjustment intervals according to the noise segmentation value of 2dB.
[0071] Step S110: Determine the total speed regulation time based on the number of speed regulation intervals and the unit speed regulation time corresponding to the initial user information.
[0072] Specifically, the unit speed adjustment duration corresponding to the initial user information can be preset, depending on the usage scenario and user preferences. Once the number of speed adjustment intervals is determined, multiplying it by the preset unit speed adjustment duration yields the total speed adjustment duration.
[0073] In some preferred embodiments of the present invention, the unit speed adjustment duration corresponding to the initial user information is determined based on a subjective evaluation method.
[0074] Specifically, the subjective evaluation method can involve selecting a certain number of test subjects, typically people around 40 years old, playing the sound of the range hood operating at various adjustment times, and then selecting the most suitable time as the unit speed adjustment time through subjective evaluation and scoring. This method can simply and quickly determine the unit speed adjustment time.
[0075] Step S112: Obtain current user information.
[0076] Specifically, before implementing a speed adjustment scheme, the controller needs to obtain relevant information about the current user. This information may include the user's age group, gender, and usage habits. By collecting this information, the controller can better understand the user's needs and preferences, thereby providing them with more personalized services. For example, young people may prefer a fast and powerful speed adjustment effect, while older people may prefer a smooth and comfortable speed adjustment process. Therefore, based on the characteristics of different users, the controller can adjust the speed adjustment scheme to meet their needs.
[0077] Step S114: If the current user information is inconsistent with the preset initial user information, determine the target speed regulation time corresponding to the speed regulation interval based on the current user information, the reference information, the total speed regulation time and the number of speed regulation intervals.
[0078] Specifically, if the current user information is found to be inconsistent with the preset initial user information, the controller needs to recalculate the target speed adjustment duration for each speed adjustment interval. This process requires considering factors such as the current user information, baseline information (i.e., initial user information, which may include the initial user's age), total speed adjustment duration, and the number of speed adjustment intervals. By integrating these factors, the controller can calculate the target duration for each speed adjustment interval, ensuring that the entire speed adjustment process meets user needs while maintaining high efficiency and stability.
[0079] Furthermore, in some preferred embodiments of the present invention, the current user information includes the current user's age; the baseline information includes the baseline age, i.e., the age of the initial user; and the target speed adjustment duration is determined by the following formula: Among them, T 单次 T represents the target speed regulation duration corresponding to the speed regulation range. 总 The total duration of speed adjustment is given by n, the number of speed adjustment intervals is given by n, and the current user's age is given by N. 分 The baseline age is used.
[0080] Specifically, N 分 Divide the age into middle-aged and young adults and the elderly, for example, set 40 years old as the dividing line, and N is the user's age.
[0081] Furthermore, in some preferred embodiments of the present invention, after the step of obtaining the current user information, the method further includes: if the current user information is consistent with the preset initial user information, determining the speed regulation scheme based on the total speed regulation duration, the number of speed regulation intervals, and the rotational speed corresponding to the endpoints of the speed regulation intervals.
[0082] Specifically, this means that further adjustments to the speed adjustment time are not required based on identity information. The controller first analyzes the total time required from the start to the end of the working gear shift range. This time reflects the overall speed of the adjustment process and determines the urgency and smoothness of the adjustment. A longer total adjustment time means the adjustment process can be smoother, while a shorter time may require faster adjustments to quickly reach the target gear.
[0083] Next, the controller needs to determine the number of intervals in the entire speed regulation process. These intervals subdivide the entire speed regulation process into multiple smaller stages, each with its specific speed range and running time. The number of intervals depends on the noise separation value and the user's sensitivity to noise changes. By setting a reasonable number of intervals, the speed regulation process can be ensured to be both precise and efficient. For each speed regulation interval, the controller identifies the speeds corresponding to its start and end points. These speed values are key parameters for developing the speed regulation scheme, directly determining the fan's operating speed and corresponding noise level. By precisely controlling the speed of each interval, it can be ensured that the noise varies within a preset range, thereby avoiding sudden noise peaks or uncomfortable quiet periods.
[0084] Finally, based on the above analysis, the controller developed a specific speed control scheme. This scheme details how the fan should adjust its speed within each speed control range, including accelerating, decelerating, or maintaining the current speed. The goal of the scheme is to maintain the noise level within the user's acceptable range throughout the entire speed control process, while ensuring that the fan can smoothly and accurately reach the target speed.
[0085] The controller can accurately formulate the most suitable speed regulation scheme based on the current user information and equipment status, which not only meets the user's noise control requirements, but also ensures the efficient operation of the fan.
[0086] Furthermore, in some preferred embodiments of the present invention, after the step of obtaining the current user information, the method further includes: if the current user information is consistent with the initial user information, determining the total speed adjustment duration as the target speed adjustment duration.
[0087] Specifically, if the current user information is consistent with the initial user information, it means that the initial user is using the range hood and the initially set unit duration is also consistent with it. By directly setting the total speed adjustment duration as the target speed adjustment duration, a better experience can be achieved.
[0088] Step S116: Determine the speed regulation scheme based on the target speed regulation duration and the rotational speeds corresponding to the endpoints of the speed regulation range.
[0089] Specifically, the final speed control scheme is determined based on the target speed control duration and the rotational speeds corresponding to the endpoints of the speed control intervals. During this process, the controller needs to comprehensively consider the relationship between the target duration and the endpoint rotational speeds of each speed control interval to ensure the continuity and smoothness of the entire speed control process. Simultaneously, the controller also needs to consider other factors, such as the impact of ambient temperature and humidity on fan performance, in order to adjust the speed control scheme according to actual conditions. In this way, the controller can provide a highly efficient, stable, and user-friendly speed control method for the range hood.
[0090] Furthermore, in some preferred embodiments of the present invention, the method further includes: responding to an externally input shutdown command, determining whether the shutdown command is a false trigger; if the shutdown command is a false trigger, maintaining operation.
[0091] Specifically, when a user sends a shutdown command via an external input interface (such as a touchscreen, button, or remote control), the controller immediately receives and accurately identifies the intent and type of the command. Upon receiving the shutdown command, the controller does not immediately execute the shutdown procedure. Instead, it enters a brief standby state, which can last from a few seconds to over ten seconds, depending on user settings or system presets. During this time, the controller monitors for any new command inputs, including repeated shutdown commands or other operation commands. If the controller does not receive any new commands during this standby period, it determines that the initial shutdown command was likely a false trigger. In this case, the controller will ignore the false shutdown command, and the range hood will continue its current operation without interrupting ongoing tasks. On the other hand, if a repeated shutdown command or other confirmation of shutdown is received during the standby period, the controller will determine that the user genuinely intends to turn off the range hood. At this point, the controller will safely shut down the device according to a pre-defined procedure, ensuring that no unexpected situations occur during the shutdown process.
[0092] Regardless of the action the controller decides to take (maintain operation or safe shutdown), it provides clear feedback to the user. This can be achieved through visual signals on the interface, audio prompts, or push notifications sent to the user's mobile device. This allows the user to clearly understand whether their command has been correctly recognized and executed, or has been deemed a misoperation and ignored. The control system intelligently distinguishes between the true intent and the misoperation, ensuring smooth equipment use while avoiding inconvenience caused by misoperation, thus improving the user experience.
[0093] Step S118, End.
[0094] Specifically, the range hood controller executes a speed adjustment scheme to regulate the fan speed. The result of executing this scheme may be to stop the fan from running, putting the range hood into standby mode, or it may set the fan to a new speed, thus adjusting the range hood's operating level.
[0095] This invention provides a fan control method applied to a range hood controller, comprising: responding to an externally input working speed switching command and acquiring the working speed change range; determining the noise change range corresponding to the working speed change range; dividing the noise change range into multiple speed adjustment ranges based on a preset noise segmentation value; determining the total speed adjustment time based on the number of speed adjustment ranges and the unit speed adjustment time corresponding to the initial user information; acquiring current user information; if the current user information is inconsistent with the preset initial user information, determining the target speed adjustment time corresponding to the speed adjustment range based on the current user information, reference information, total speed adjustment time, and number of speed adjustment ranges; determining the speed adjustment scheme based on the target speed adjustment time and the rotational speed corresponding to the endpoints of the speed adjustment ranges; firstly, the noise that may be caused by adjusting the working state is divided into multiple speed adjustment ranges according to the preset noise segmentation value, and then the speed adjustment time is further adjusted by acquiring the user's identity information; the speed adjustment scheme of the range hood fan is determined by the adjusted speed adjustment range and speed adjustment time, and the speed is intelligently adjusted according to the user's identity, reducing speed adjustment noise and improving the user experience.
[0096] Example 2
[0097] Based on the above embodiments, this invention provides another fan control method, see [link to relevant documentation]. Figure 2 The flowchart shown in this embodiment of the invention provides another fan control method, which includes:
[0098] Step S202, Start. The range hood is in a power-on standby state, waiting for the start-up command; or, the range hood is running at a stable speed, waiting for user commands or operating information sent by linked devices.
[0099] Step S204, User Information Input. Enter user information, including at least age information.
[0100] Step S206, User Data Analysis. The user data is analyzed; the specific analysis process is described in step S208.
[0101] Step S208: Determine if the user is a young or middle-aged adult. If so, set the noise segmentation value to 3dB; otherwise, proceed to step S210.
[0102] Step S210: Determine if the user is an elderly person. If the user is determined to be an elderly person, the noise segmentation value is set to 2dB.
[0103] Step S212: Increase noise reduction sensitivity output. Based on the noise segmentation value determined in step S208 or step S210, increase the noise reduction sensitivity output, which is 3dB or 2dB.
[0104] Step S214, Determine the initial operating gear of the fan. Determine the operating gear of the fan, which is the operating gear before gear adjustment.
[0105] Step S216, Shift Up Current Determination. Determine the change value of the shift up current, the current corresponding to the desired shift level, and the current corresponding to the shift level before shifting.
[0106] Step S218, determine the upshift speed. The speed variation range is determined based on the aforementioned current. The speed variation range also corresponds to the noise variation range.
[0107] Step S220: Divide the acceleration interval based on the sensitive segment. Sensitivity is the noise segmentation value corresponding to different groups of people. Dividing the noise variation range according to the noise segmentation value actually corresponds to dividing the speed variation range, and also obtains the number of speed regulation intervals; in some preferred embodiments of the present invention, the number of speed regulation intervals is rounded up.
[0108] Step S222: Time division based on user data. The controller pre-stores the total time required for each adjustment unit. For example, the time required to go from standby to low speed is t1, from low speed to high speed is t2, from high speed to stir-fry speed is t3, and so on. It should be emphasized that in existing products, the range hood speed division is more detailed, and more speed adjustment times can be set accordingly. These times can be determined based on subjective evaluation. The time is divided according to the total time and the number of speed adjustment intervals, generally evenly; for example, if the total time is 10 seconds and the number of speed adjustment intervals is 5, the time corresponding to a single speed change interval is 2 seconds.
[0109] Step S224: Confirm the time interval. In some preferred embodiments of this invention, it is further necessary to determine the time corresponding to a single speed change interval. If it does not meet the preset warning time threshold, that is, if the time corresponding to a single speed change interval is too large or too small, the controller will issue a warning message, and further checks of the hardware and control software are required.
[0110] Step S226: The range hood starts in stages. The speed is adjusted according to the speed and adjustment time at the endpoints of the speed adjustment range; during the start-up phase, the speed at one endpoint of the first speed adjustment range is 0.
[0111] In typical application scenarios, steps S202 to S226 described above can meet the needs of most initial users. In some preferred embodiments of the present invention, subsequent steps S228 to S236 are required to perform further speed adjustment based on user information.
[0112] Step S228: Determine if the user is an initial user. A user determination is required to determine if the current user is an initial user.
[0113] Step S230: Maintain the original speed control mode. If it is a new user, continue to maintain the original speed control mode.
[0114] Step S232, adjust the sensitivity of the range hood. If you are not a new user, you need to adjust the sensitivity of the range hood. In fact, you can directly adjust the speed adjustment time corresponding to the speed adjustment range.
[0115] Step S234, Optimize the time period adjustment. Optimize the time period adjustment based on the user's age. The user's age can be determined through a combination of manual input, facial recognition technology, and voice recognition technology.
[0116] Step S236: Run the new adjustment mode. Determine the new adjustment mode using the optimized time and execute the new adjustment mode.
[0117] In some preferred embodiments of the present invention, steps S204 to S236 above can correspond to the speed adjustment of the range hood when it is turned on. During the operation of the range hood, it is necessary to continuously monitor the operating status of the range hood and the operating status of the linked devices, especially the operating status of the linked cooktop. Starting from step S238, the embodiments of the present invention introduce fan speed adjustment based on the operating status of the linked cooktop.
[0118] Step S238, Range Hood Operation Status Detection. During the operation of the range hood, its operating status is continuously monitored. In some preferred embodiments of the present invention, the operating status of linked devices can also be monitored, or information sent by linked devices can be received.
[0119] Step S240: Determine if the stove is off. The operating status of the range hood is determined based on whether the stove is off. If the stove is not off, proceed to step S252 to maintain the current operating status.
[0120] Step S242, Accidental Touch Detection. If the stove goes out, determine whether it was an accidental touch. The specific determination process is performed in step S244.
[0121] Step S244: Continuously monitor whether the engine is off for time T. The step to determine if a false trigger is triggered can be directly determined by whether the engine has been off for a continuous time T.
[0122] Step S246, Determine the current speed. If the stove remains off for a continuous time T, determine the current speed of the range hood fan. Use the current speed as the first endpoint of the speed adjustment range, and 0 speed as the second endpoint.
[0123] In some preferred embodiments of the present invention, if it is simply a downshift adjustment and not an engine shutdown, step S248 is executed to determine the speed at which the gear is downshifted. The speed after downshifting is taken as the second endpoint of the speed adjustment range.
[0124] Step S250: Based on the division of the sensitive section speed reduction range. Based on the divided speed reduction range, the range hood will shut down or reduce speed in stages.
[0125] After step S244, if the stove is not kept off for a continuous time T, it is determined that the stove was accidentally turned off, and step S252 is executed to maintain the operation of the range hood.
[0126] Step S254, End.
[0127] Specifically, the range hood controller executes a speed adjustment scheme to regulate the fan speed. The result of executing this scheme may be to stop the fan from running, putting the range hood into standby mode, or it may set the fan to a new speed, thus adjusting the range hood's operating level.
[0128] This invention provides another fan control method. The first stage requires inputting initial user information. It's worth noting that people of different ages have different noise sensitivities. For example, young and middle-aged people may only perceive a noticeable change at around 3dB, while older people feel a significant noise change at 2dB. Therefore, by inputting basic information, the sensitive segment of the speed-up phase can be determined. After outputting the corresponding sensitive segment, it's necessary to clarify the speed setting the user needs to adjust during the first stage of product use. Most current range hoods offer multi-speed adjustment, with each setting corresponding to a current level, which indicates the rotational speed. Therefore, based on age group, the required rotational speed range for each step adjustment can be determined. After determining the time range, the time required for each adjustment needs to be specified, as the adjustment time is related to the age of the user group. Each time interval is then set. After adjusting the decibel level and adjustment time, the range hood can begin its stepped start-up. Considering that users may change, it is necessary to determine user consistency (this determination can be based on facial recognition or voice control). If the consistency is consistent, the original control can be maintained. If there is a discrepancy, adjustments are made, and the adjustment time period is optimized so that the range hood operates in the new adjustment mode. The operating status is monitored. If the stove flame goes out, indicating the end of cooking, the range hood needs to be turned off. The procedure for turning off the range hood should first confirm accidental shutdown, continuously monitor whether the flame is turned off for time T. If the flame is confirmed to be turned off, the current operating status is determined, the current speed is output, and the current gradient is reduced. This reduces user annoyance and minimizes the impact of harsh noise on users.
