[0053] Embodiment 1

[0054] The embodiment of the present invention provides a fan control method, which is applied to a controller of a range hood, see Figure 1 The flowchart of a fan control method provided by an embodiment of the present invention is shown, and the method includes:

[0055] Step S102, start.

[0056] Specifically, the range hood is in a powered-on standby state, waiting for a power-on and operating instruction; or, the range hood is powered on and running in a stable gear, waiting for a user instruction or operating information sent by a linkage device at any time.

[0057] Step S104, responding to an externally input working gear switching instruction, obtaining a working gear change interval.

[0058] Specifically, in the range hood controller, when the user sends a working gear switching instruction through an external input device (such as a button, touch screen, etc.), the controller will receive this instruction and process it. First, the controller needs to identify the current working gear and the target working gear, and then calculate the change interval between the two gears. This change interval refers to the range of change of the air volume. After obtaining this change interval, the controller can determine the corresponding speed regulation scheme according to the preset algorithm.

[0059] It is common that during the process of turning the range hood on and off, the noise changes greatly due to the rapid change in fan speed. After the on and off command is recognized, the gear change range is determined. For example, when the range hood is turned on, the current gear is 0, and the target working gear after turning on is 5. The change range corresponds to the air volume change range corresponding to the 5 gears.

[0060] Step S106, determining the noise variation range corresponding to the working gear variation interval.

[0061] Specifically, after determining the working gear change range, the controller needs to further analyze the noise change range corresponding to this range. The noise change range refers to the change range of the noise intensity generated by the range hood during the entire speed regulation 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 variation interval includes: determining the current variation range corresponding to the working gear variation interval; and determining the noise variation range corresponding to the current variation range.

[0063] Specifically, when the working gear changes, it is first necessary to determine the current demand range corresponding to the change. Different gears correspond to different motor operating currents. High gears usually require higher currents to provide stronger wind power, while low gears require lower currents. The current values ​​corresponding to different gears can be obtained by precise measurement or consulting the equipment specifications. For example, if the gear is switched from low gear to high gear, the controller will monitor the motor from a lower current consumption state to a higher current consumption state.

[0064] The current consumption of the motor has a direct relationship with the noise level. Generally speaking, an increase in current means an increase in the motor speed, which generates more noise. In order to determine the range of noise changes corresponding to the current change, experimental data or technical parameters provided by the motor manufacturer can be used. By comparing the noise test results at different current levels, a model of the corresponding relationship between current and noise level can be established. This model will help the controller predict the noise change within a specific current change range.

[0065] The controller can accurately determine the corresponding noise change range according to the change of working gear. This process is the key to ensure that the range hood can maintain the ideal noise level when switching between different gears, and also provides the necessary basis for the subsequent speed regulation strategy.

[0066] Step S108: dividing the noise variation range into a plurality of speed adjustment intervals based on a preset noise segmentation value.

[0067] Specifically, in order 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. In this way, 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 ​​according to the sensitivity of different groups of people to noise. 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 working state of the range hood can be adjusted as soon as possible without affecting the user experience.

[0069] Furthermore, in some preferred embodiments of the present invention, after a preliminary questionnaire survey, the population is divided into three levels according to age, namely young, middle-aged, and elderly. The noise sensitivity increases in sequence, and the setting range also changes in sequence. The elderly are more sensitive to changes above 2dB, but middle-aged and young people may be more sensitive to changes above 3dB.

[0070] For example, if the noise variation range is 6 dB, corresponding to the elderly group, the noise variation range is divided into three speed adjustment intervals according to the noise segmentation value of 2 dB.

[0071] Step S110, determining the total speed adjustment duration based on the number of speed adjustment intervals and the unit speed adjustment duration corresponding to the initial user information.

[0072] Specifically, the unit speed adjustment duration corresponding to the initial user information can be preset according to different usage scenarios, user preferences, etc. The number of speed adjustment intervals is determined, and the total speed adjustment duration is obtained by multiplying the preset unit 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 be to select a certain number of test people, generally people around 40 years old can be selected as testers, play the operating sounds of the range hood with various adjustment durations, and select the most appropriate time as the unit speed adjustment duration through subjective evaluation and scoring. This method can simply and quickly determine the unit speed adjustment duration.

[0075] Step S112, obtaining current user information.

[0076] Specifically, before implementing the speed adjustment scheme, the controller needs to obtain relevant information about the current user. This information may include the user's age group, gender, usage habits, etc. By collecting this information, the controller can better understand the user's needs and preferences, and thus provide them with more personalized services. For example, for young people, they may prefer a fast and powerful speed adjustment effect; while for the elderly, they may prefer a smooth and comfortable speed adjustment process. Therefore, according to 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, a target speed adjustment duration corresponding to the speed adjustment interval is determined based on the current user information, the benchmark information, the total speed adjustment duration and the number of speed adjustment intervals.

[0078] Specifically, if the current user information is found to be inconsistent with the preset initial user information after obtaining it, the controller needs to recalculate the target speed regulation duration corresponding to the speed regulation interval. This process needs to consider factors such as the current user's information, the benchmark information (that is, the initial user information, which may include the age of the initial user), the total speed regulation duration, and the number of speed regulation intervals. By combining these factors, the controller can calculate the target duration of each speed regulation interval, so that the entire speed regulation process can meet the needs of users while maintaining efficiency and stability.

[0079] Further, in some preferred embodiments of the present invention, the current user information includes the current user age; the benchmark information includes the benchmark age, that is, the age of the initial user; and the target speed adjustment duration is determined by the following formula: Among them, T 单次 is the target speed regulation duration corresponding to the speed regulation interval, T 总 is the total speed adjustment time, n is the number of speed adjustment intervals, N is the current user age, N 分 is the base age.

[0080] Specifically, N 分 The age division between young and middle-aged people and the elderly, for example, 40 years old is set as the watershed, 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 also 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 time, the number of speed regulation intervals and the speed corresponding to the endpoints of the speed regulation intervals.

[0082] Specifically, this means that there is no need to further adjust the speed regulation time through identity information. First, the controller analyzes the total time required from the start to the end of the working gear change interval. This time reflects the overall speed of the speed regulation process and determines the urgency and smoothness of the speed regulation. A longer total speed regulation time means that the speed regulation process can be smoother, while a shorter time may require faster adjustment 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 are a subdivision of the entire speed regulation process into multiple small stages, each with its own 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 meticulous and efficient. For each speed regulation interval, the controller identifies the speed corresponding to its starting and ending endpoints. These speed values ​​are key parameters for formulating speed regulation plans, and they directly determine the operating speed of the fan and the corresponding noise level. By accurately 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 develops a specific speed regulation plan. This plan specifies in detail how the fan should adjust the speed in each speed regulation range, including acceleration, deceleration, or maintaining the current speed. The goal of the plan is to keep the noise level within the user's acceptable range during the entire speed regulation process, while ensuring that the fan can reach the target gear smoothly and accurately.

[0085] The controller can accurately formulate the most appropriate speed regulation plan based on current user information and equipment status, which not only meets the user's needs for noise control, 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, indicating that the initial user is using the range hood, the initially set unit time is also adapted thereto, and the total speed adjustment time is directly determined as the target speed adjustment time, so that the user can have a better experience.

[0088] Step S116, determining a speed regulation scheme based on the target speed regulation duration and the speeds corresponding to the endpoints of the speed regulation interval.

[0089] Specifically, the final speed regulation scheme is determined based on the target speed regulation duration and the speed corresponding to the endpoint of the speed regulation interval. In this process, the controller needs to comprehensively consider the relationship between the target duration and the endpoint speed of each speed regulation interval to ensure the continuity and smoothness of the entire speed regulation process. At the same time, the controller also needs to consider other factors, such as the impact of ambient temperature, humidity, etc. on fan performance, so as to adjust the speed regulation scheme according to actual conditions. In this way, the controller can provide an 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 the user sends a shutdown command through an external input interface (such as a touch screen, button or remote control), the controller immediately receives and accurately identifies the intention and type of this command. Once the shutdown command is received, the controller will not immediately execute the shutdown procedure. Instead, it enters a short standby state, which can be from a few seconds to more than ten seconds, depending on the user setting or system preset. During this time, the controller monitors whether there are any new command inputs, including repeated shutdown commands or other operation commands. If the controller does not receive any new commands during this standby time, it will determine that the initial shutdown command is likely to be a false touch. In this case, the controller will ignore the false shutdown command, and the range hood will continue to maintain the current operating state without interrupting the ongoing operation. On the other hand, if a repeated shutdown command or other confirmation shutdown operation is received during the standby period, the controller will determine that the user does intend to turn off the range hood. At this time, the controller will safely shut down the device according to the predetermined procedure to ensure that no unexpected situations occur during the shutdown process.

[0092] Whatever action the controller decides to perform (maintain operation or shut down safely), it provides clear feedback to the user. This can be achieved through visual signals on the interface, sound prompts, or push notifications sent to the user's mobile device. This allows users to clearly know whether their instructions have been correctly identified and executed, or have been ignored as misoperations. The control system can intelligently distinguish the difference between true intentions and misoperations, which not only ensures the smooth use of the equipment, but also avoids the inconvenience caused by misoperations and improves the user experience.

[0093] Step S118, end.

[0094] Specifically, the controller of the range hood executes the speed regulation scheme to regulate the speed of the fan. The result of executing the speed regulation scheme may be to end the operation of the fan and put the range hood into a standby state, or to make the fan run at a new speed to adjust the working gear of the range hood.

[0095] The present invention provides a fan control method, which is applied to a controller of a range hood, comprising: responding to an externally input working gear switching instruction to obtain a working gear change interval; determining a noise change range corresponding to the working gear change interval; dividing the noise change range into a plurality of speed regulation intervals based on a preset noise segmentation value; determining a total speed regulation time based on the number of speed regulation intervals and a unit speed regulation time corresponding to initial user information; obtaining current user information; if the current user information is inconsistent with the preset initial user information, determining a target speed regulation time corresponding to the speed regulation interval based on the current user information, reference information, the total speed regulation time and the number of speed regulation intervals; determining a speed regulation scheme based on the target speed regulation time and the speed corresponding to the endpoints of the speed regulation interval; firstly dividing the noise that may be caused by adjusting the working state according to the preset noise segmentation value to obtain a plurality of speed regulation intervals, and then further adjusting the speed regulation time by obtaining the user's identity information, determining the speed regulation scheme of the range hood fan according to the adjusted speed regulation interval and speed regulation time, intelligently adjusting the speed according to the user identity, reducing the speed regulation noise, and improving the user experience.

[0096] Embodiment 2

[0097] Based on the above embodiment, the present invention provides another fan control method. Figure 2 The flowchart of another fan control method provided by an embodiment of the present invention is shown, and the method includes:

[0098] Step S202, start. The range hood is in a powered-on standby state, waiting for a power-on command; or the range hood is powered on and running in a stable gear, waiting for a user command or operation information sent by a linkage device at any time.

[0099] Step S204: Input user information: Input user information, including at least age information.

[0100] Step S206: User data analysis: Analyze the user, and the specific analysis process is step S208.

[0101] Step S208, determining whether the user is a young or middle-aged person. If the user is a young or middle-aged person, the noise segmentation value is determined to be 3dB; if the user is not a young or middle-aged person, executing step S210.

[0102] Step S210: Determine the user as an elderly group. If the user is determined to be an elderly group, the noise segmentation value is determined to be 2 dB.

[0103] Step S212: Outputting the upshift noise reduction sensitivity. Outputting the upshift noise reduction sensitivity according to the noise segmentation value determined in step S208 or step S210, that is, 3dB or 2dB.

[0104] Step S214, determining the initial operating gear position of the fan: determining the fan's operating gear position, that is, the operating gear position before the gear adjustment.

[0105] Step S216, upshift current determination: Determine the change value of the upshift current, determine the current corresponding to the gear to be reached, and the current corresponding to the gear before the gear is adjusted.

[0106] Step S218, upshift speed determination. The speed variation range is determined based on the above current. The speed variation range also corresponds to the noise variation range.

[0107] Step S220, based on the sensitive section speed increase interval division. Sensitivity is the noise segmentation value corresponding to different groups of people. Dividing the noise change range according to the noise segmentation value actually corresponds to dividing the speed change range, and also obtains the number of speed adjustment intervals; in some preferred embodiments of the present invention, the number of speed adjustment intervals is rounded up.

[0108] Step S222, time division based on user data. The total time required for the adjustment unit is pre-stored in the controller. For example, the time required to go from the standby state to the weak gear is t1, the time required to go from the weak gear to the strong gear is t2, the time required to go from the strong gear to the stir-fry gear is t3, and so on. It should be emphasized that in the existing products, the gear division of the range hood is more detailed, and more speed adjustment times can be set accordingly. These times can be determined based on the subjective evaluation method. The time is divided according to the total time and the number of speed adjustment intervals, generally equally; for example, the total time is 10 seconds, the number of speed adjustment intervals is 5, and the time corresponding to a single speed change interval after division is 2 seconds.

[0109] Step S224, confirming the time interval. In some preferred embodiments of the present 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, the time corresponding to a single speed change interval is too long or too short, the controller will issue a warning message, and further check the hardware device and control software is required.

[0110] Step S226, the range hood is started stepwise. The gear is adjusted according to the speed and speed adjustment time at the end points of the speed adjustment interval; in the start-up phase, the speed at one end point of the first speed adjustment interval is 0.

[0111] In general application scenarios, the above steps S202 to S226 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 correction based on user information.

[0112] Step S228, determine whether the user is an initial user. It is necessary to perform user determination to determine whether the current user is an initial user.

[0113] Step S230, maintaining the original speed adjustment mode. If it is an initial user, continue to maintain the original speed adjustment mode.

[0114] Step S232, adjusting the sensitivity of the range hood. If the user is not a new user and needs to adjust the sensitivity of the range hood, the speed adjustment time corresponding to the speed adjustment interval can actually be directly adjusted.

[0115] Step S234, optimizing the adjustment time period. The adjustment time period is optimized according to the user's age. The user's age can be comprehensively determined by manual input, face recognition technology, and voice recognition technology.

[0116] Step S236: New adjustment mode is run. The new adjustment mode is determined using the optimized time and executed.

[0117] In some preferred embodiments of the present invention, the above steps S204 to S236 may correspond to the gear adjustment of the range hood startup state. During the operation of the range hood, it is necessary to continuously monitor the operation state of the range hood and the operation state of the linkage equipment, especially the operation state of the linkage stove. Starting from step S238, the embodiment of the present invention introduces the fan speed adjustment based on the operation state of the linkage stove.

[0118] Step S238, detection of the operating status of the range hood. The operating status of the range hood is continuously detected during its operation. In some preferred embodiments of the present invention, the operating status of the device linked thereto may also be monitored, or information sent by the linked device may be received.

[0119] Step S240, determining whether the stove is turned off. Determine the operating state of the range hood according to whether the stove is turned off. If the stove is not turned off, execute step S252 to maintain the current operating state.

[0120] Step S242, false touch determination: If the stove is turned off, it is determined whether it is a false touch, and the specific determination process is performed in step S244.

[0121] Step S244, continuously monitoring whether the engine is turned off for a period of time T. The step of determining the false touch can directly determine whether the engine is turned off for a period of time T.

[0122] Step S246, current speed determination: If the cooker remains off for the continuous time T, the current speed of the range hood fan is determined. The current speed is used as the first endpoint of the speed adjustment interval, and 0 speed is used as the second endpoint.

[0123] In some preferred embodiments of the present invention, if it is just a simple downshift adjustment and not a flameout, step S248 is executed to determine the speed of the downshift and take the speed after the downshift as the second endpoint of the speed adjustment interval.

[0124] Step S250, based on the speed reduction interval division of the sensitive section, the range hood is shut down or speed reduced in a stepwise manner based on the divided speed reduction interval.

[0125] After step S244, if the stove does not remain off for the continuous time T, it is determined that the stove is turned off by mistake, and step S252 is executed to keep the range hood running.

[0126] Step S254, end.

[0127] Specifically, the controller of the range hood executes the speed regulation scheme to regulate the speed of the fan. The result of executing the speed regulation scheme may be to end the operation of the fan and put the range hood into a standby state, or to make the fan run at a new speed to adjust the working gear of the range hood.

[0128] The embodiment of the present invention provides another fan control method. In the first stage, initial user information needs to be input. It is worth noting that people of different age groups have different sensitivity to noise. For example, young and middle-aged people may feel obvious changes at around 3dB, while the elderly feel that the noise change is obvious at 2dB. Therefore, the sensitive segment of the speed-up stage can be determined by inputting basic information; after the corresponding sensitive segment is output, it is necessary to clarify the gear that the user needs to adjust in the first stage of using the product. Currently, most range hoods are adjusted in multiple gears, and the corresponding gears have corresponding currents. The corresponding current can know the speed. Therefore, according to the age group, the speed range that needs to be changed for each step adjustment can be known; after determining the time interval, it is necessary to clarify the time required for each adjustment, and the adjustment time is related to the age of the user group; set each time period After adjusting the decibel value and the time, the range hood can be started in a step-by-step manner; considering that the users will change, it is necessary to judge the user consistency (the judgment here can be combined with face and voice control). If the consistency is the same, the original control can be maintained. If there is a gap with the original, adjustments will be made to optimize the adjustment time period so that the range hood can operate in the new adjustment mode; the operating status is monitored. If the stove is turned off, which means that the cooking step has ended, the range hood needs to be shut down. The procedure for shutting down the range hood should be to confirm the false shutdown first, and continuously monitor whether the fire is turned off within the T time. If it is confirmed that the fire is turned off, the current operating status is judged, the current speed is output, and the current gradient is reduced; reduce the annoyance of use and reduce the impact of bad noise on personnel.
