Description

Technical Field

[0001] This invention belongs to the field of kitchen appliance control, and particularly relates to a range hood and its adjustment and control method and device. Background Technology

[0002] Generally, users need to manually change the operating status of the range hood, and forgetting to turn it on during cooking can negatively impact the cooking experience. As people pursue a higher quality of life, range hoods can be equipped with smoke concentration detection devices to monitor the smoke concentration generated during cooking and adjust the fan speed accordingly. However, the relationship between smoke concentration and fan speed is fixed, and simply adjusting the fan speed to follow changes in smoke concentration cannot meet the personalized needs of users. Summary of the Invention

[0003] This invention provides a range hood and its adjustment and control method and device, which at least to some extent solves the technical problem that the fan air volume of the range hood cannot meet the personalized needs of users when the smoke concentration changes.

[0004] In a first aspect, embodiments of the present invention provide a range hood adjustment and control method, comprising: acquiring manual adjustment data of the range hood by a user, the manual adjustment data including the smoke concentration and the fan airflow after the user manually adjusts the fan speed within a target historical period; updating the adjustment and control data of the range hood based on the manual adjustment data, the adjustment and control data being the relationship data between smoke concentration and fan airflow, used to control the fan airflow of the range hood to follow the change in smoke concentration in the current environment of the range hood.

[0005] In conjunction with the first aspect, some implementations also include: adjusting the fan airflow of the range hood based on the adjustment and control data during the operation of the range hood.

[0006] In conjunction with the first aspect, in some implementations, adjusting the fan airflow of the range hood based on the adjustment control data includes: monitoring the actual smoke concentration in the current environment where the range hood is located and the current actual airflow of the range hood; comparing whether the current actual airflow is the same as a first target airflow, where the first target airflow is the airflow value in the adjustment control data corresponding to the actual smoke concentration; if they are different, adjusting the fan airflow of the range hood to the first target airflow.

[0007] In conjunction with the first aspect, in some implementations, the adjustment and control data of the range hood includes multiple sub-control curves. Adjusting the fan airflow of the range hood based on the adjustment and control data includes: determining a target sub-control curve corresponding to the current moment from the multiple sub-control curves; and adjusting the fan airflow of the range hood according to the determined target sub-control curve, so that the fan airflow of the range hood follows the change in smoke concentration in the current environment of the range hood.

[0008] In conjunction with the first aspect, in some implementations, determining the target sub-control curve corresponding to the current moment from the plurality of sub-control curves includes: detecting the light level of the environment in which the range hood is currently located; and determining the first sub-control curve or the second sub-control curve as the target sub-control curve based on the light level.

[0009] In conjunction with the first aspect, in some implementations, the step of obtaining the user's manual adjustment data for the range hood is re-executed each time a preset data update condition is met, in order to obtain new manual adjustment data.

[0010] In conjunction with the first aspect, in some implementations, updating the adjustment control data of the range hood based on the manual adjustment data includes: preprocessing the manual adjustment data; and updating the adjustment control data based on the preprocessed data to update the correspondence between smoke concentration and fan airflow in the adjustment control data.

[0011] In conjunction with the first aspect, in some implementations, updating the adjustment and control data based on the preprocessed data includes: dividing the preprocessed data into multiple data subsets that correspond one-to-one with the multiple sub-control curves; and updating the multiple sub-control curves based on the multiple data subsets.

[0012] In conjunction with the first aspect, in some implementations, the manual adjustment data includes multiple data records, and each data record includes the smoke concentration when the user manually adjusts the fan speed of the range hood once and the fan volume after adjustment. The preprocessing of the manual adjustment data includes: acquiring scene data of the range hood; performing enhancement processing on each data record in the manual adjustment data based on the scene data to obtain enhanced adjustment data; and classifying and labeling each data record in the enhanced adjustment data to form the preprocessed data.

[0013] In conjunction with the first aspect, in some implementations, the classification and labeling of each data record in the enhanced adjustment data includes: if no change in fan airflow occurs based on the adjustment control data, and any manual adjustment operation by the user is detected, a first data record is generated, and a classification mark indicating a missed judgment is made for the first data record; if a first manual adjustment operation by the user is detected within a preset time period for adjusting the fan airflow based on the adjustment control data, a second data record is generated, and a classification mark indicating a misjudgment is made for the second data record, wherein the fan airflow adjusted based on the first manual adjustment operation is the same as the fan airflow adjusted based on the adjustment control data, but in the opposite direction; if a second manual adjustment operation by the user is detected within a preset time period for adjusting the fan airflow based on the adjustment control data, a third data record is generated, and a classification mark indicating a correct judgment but incorrect single airflow adjustment is made for the third data record, wherein the fan airflow adjusted based on the second manual adjustment operation is different from the fan airflow adjusted based on the adjustment control data.

[0014] Secondly, embodiments of the present invention provide a range hood adjustment and control device, comprising: a data acquisition unit, configured to acquire manual adjustment data of the range hood by a user, the manual adjustment data including the smoke concentration and the fan airflow after adjustment when the user manually adjusts the fan speed within a target historical period; and a data update unit, configured to update the adjustment and control data of the range hood based on the manual adjustment data, the adjustment and control data being the relationship data between smoke concentration and fan airflow, configured to control the fan airflow of the range hood to follow the changes in smoke concentration in the current environment of the range hood.

[0015] Thirdly, embodiments of the present invention provide a range hood, including one or more processors and one or more memories, wherein the one or more memories store at least one piece of program code, and the at least one piece of program code is loaded and executed by the one or more processors to implement the method described in any embodiment of the first aspect.

[0016] In one or more technical solutions provided by the embodiments of the present invention, the adjustment and control data of the range hood is updated based on the user's manual adjustment data in historical time periods. This updates the relationship data between smoke concentration and fan air volume, thereby controlling the fan air volume of the range hood to follow the changes in smoke concentration in the current environment of the range hood. This better meets the user's subjective perception needs for smoke and fumes during cooking, and is therefore more accurate. It meets the personalized and subjective smoke-free needs of different users, and the automatic adjustment of the air volume of the range hood is more intelligent, thereby reducing the user's operation of the product.

[0020] Figure 3 This is a schematic diagram of the structure of a range hood in an embodiment of the present invention. Detailed Implementation

[0021] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this invention, and not all of them. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0022] Firstly, embodiments of the present invention provide a range hood adjustment and control method, applied to a range hood. (See reference...) Figure 1 As shown, the method for adjusting and controlling a range hood provided in this embodiment of the invention includes the following steps S101 to S102:

[0023] S101. Obtain the user's manual adjustment data for the range hood. The manual adjustment data includes the smoke concentration and the fan air volume after adjustment when the user manually adjusts the fan speed within the target historical period.

[0024] To more accurately adjust the fan speed of the range hood, preset data update conditions can be set. Each time the preset data update conditions are met, steps S101 to S102 are executed again to obtain new manual adjustment data. The adjustment control data of the range hood is then updated based on the currently obtained manual adjustment data. The adjustment control data after each update better matches the user's subjective perception needs for oil fumes.

[0025] In some implementations, user manual adjustment data for the range hood can be acquired periodically. The specific data update conditions can be: a preset periodic condition; when the preset periodic condition is met at the current moment, the manual adjustment data generated within the current period is acquired. For example, using a 14-day cycle, user manual adjustment data for the range hood within the most recent 14 days is acquired every 14 days to update the adjustment control data, thus updating the adjustment control data every 14 days.

[0026] In some implementations, the preset data update condition may also be: when the accuracy of the range hood's fan speed adjustment based on the control data is lower than a preset threshold, the system triggers the reacquisition of new manual adjustment data for the range hood from the user within the most recent historical period. It should be understood that the most recent historical period can be the last 14 days.

[0027] Specifically, the accuracy rate of fan airflow regulation will be the ratio of the number of incorrect adjustments based on the control data to the total number of adjustments.

[0028] In step S101, the manually adjusted data acquired for the current time can be data from the most recent week, the most recent 14 days, or the most recent month. Therefore, the manually adjusted data acquired each time is different, ensuring that the acquired data better reflects the user's subjective perception of smoke concentration.

[0029] The manual adjustment data includes: smoke concentration when the user manually increases the fan air volume and the fan air volume after the increase, smoke concentration when the user manually decreases the fan air volume and the fan air volume after the decrease, within the target historical period.

[0030] Both of the above implementation methods allow for updating and adjusting control data according to the user's personalized needs, thereby making the fan airflow changes more in line with the user's personalized requirements.

[0031] S102. Update the adjustment and control data of the range hood according to the manual adjustment data. The adjustment and control data is the relationship data between smoke concentration and fan air volume. The adjustment and control data is used to control the fan air volume of the range hood to follow the changes in smoke concentration in the current environment of the range hood.

[0032] It should be noted that the manual adjustment data includes multiple data records generated within the target historical period. Each time a user manually adjusts the fan speed of the range hood, a corresponding data record is generated. Each data record is the smoke concentration value of the environment where the range hood is located and the fan air volume after adjustment when the user manually adjusts the fan speed (increases or decreases the fan speed).

[0033] It should be understood that each data record generated within the target historical period can be directly used to update the regulation and control data, thereby updating the correspondence between smoke concentration and fan air volume in the regulation and control data.

[0034] If the regulation and control data is a data table showing a one-to-one correspondence between smoke concentration and fan air volume, then the smoke concentration values ​​in each data record manually adjusted to the same fan speed can be averaged to obtain the average smoke concentration. The average smoke concentration is then used to replace the upper and lower limits of the smoke concentration range corresponding to the fan air volume at that fan speed in the regulation and control data, thereby realizing the update of the regulation and control data.

[0035] Table 1. Regulation and Control Data

[0036]

[0037] If the control data is a curve showing the relationship between smoke concentration and fan airflow, the curve is directly corrected using each data record generated within the target historical period. Specifically, the smoke concentration values ​​in each data record manually adjusted to the same fan speed are averaged to obtain the average smoke concentration for each fan speed. Based on the correspondence between each fan speed and its corresponding average smoke concentration, the curve showing the relationship between smoke concentration and fan airflow is refitted, or the original curve showing the relationship between smoke concentration and fan airflow is corrected.

[0038] Both of the above implementation methods allow for updating and adjusting the control data according to the user's personalized needs, thus making the fan airflow changes more aligned with those needs. The difference lies in the preprocessing of the manual adjustment data, followed by updating the control data based on this preprocessed data.

[0039] Specifically, the relationship curve between smoke concentration and fan air volume is refitted using the preprocessed data.

[0040] For example, before the update, the fan airflow corresponding to the smoke concentration value A was 18 cubic meters per minute; after the update, the fan airflow corresponding to the smoke concentration value A is 18.5 cubic meters per minute.

[0041] Understandably, preprocessing the manual adjustment data includes: acquiring scene data of the range hood; enhancing each data record in the manual adjustment data based on the scene data to obtain enhanced adjustment data; and classifying and labeling each data record in the enhanced adjustment data to form preprocessed data.

[0042] The scene data can be obtained via the network and / or locally from the range hood. The obtained scene data includes location information, weather information, personnel information, holiday information, and other data that may affect the accuracy of smoke concentration detection. Before enhancement processing, the associated information for each data record might only be the range hood lighting status. After enhancement processing, the associated information for each data record includes: range hood lighting status (whether the range hood lights are on), location information, weather information, personnel information, and holiday information. This facilitates accurate classification and labeling of each data record.

[0043] The classification and labeling of each data record includes one or more of the following: smoke machine lighting status, location information, weather information, personnel information, and holiday information.

[0044] The classification and labeling of each data record includes: if no change in fan airflow occurs based on the adjustment and control data, and any manual adjustment operation by the user is detected, a first data record is generated, and a classification mark indicating a missed judgment is made for the first data record; if a user's first manual adjustment operation is detected within a preset time period for adjusting the fan airflow based on the adjustment and control data, a second data record is generated, and a classification mark indicating a misjudgment is made for the second data record, wherein the fan airflow adjusted based on the first manual adjustment operation is the same as the fan airflow adjusted based on the adjustment and control data, but in the opposite direction; if a user's second manual adjustment operation is detected within a preset time period for adjusting the fan airflow based on the adjustment and control data, a third data record is generated, and a classification mark indicating a correct judgment but incorrect airflow adjustment is made for the third data record, wherein the fan airflow adjusted based on the second manual adjustment operation is different from the fan airflow adjusted based on the adjustment and control data.

[0045] It should be understood that, in order to more precisely control the airflow of the range hood, so that the same range hood can meet the subjective perception needs of different users regarding cooking fumes, and even meet the subjective perception needs of the same user regarding cooking fumes at different times, the adjustment and control data of the range hood can include multiple different sub-control curves. Specifically, different users may have different sub-control curves, and different times may have different sub-control curves.

[0046] For example: when the ambient brightness is greater than a certain brightness threshold, it belongs to the first brightness state (e.g., during the day or when the range hood is on); when the ambient brightness is less than or equal to a certain brightness threshold, it belongs to the second brightness state (e.g., at night when the range hood is not on). The first brightness state uses the first sub-control curve, and the second brightness state uses the second sub-control curve. Another example: different sub-control curves could correspond to weekdays and non-weekdays.

[0047] Understandably, if the control data includes multiple different sub-control curves, then in step S102, each sub-control curve needs to be updated separately. Specifically, the update method is as follows: the preprocessed data is divided into multiple data subsets corresponding one-to-one with the multiple sub-control curves; the multiple sub-control curves are updated based on the one-to-one correspondence of the multiple data subsets. Specifically, multiple data subsets can be divided based on one or more classification labels of the data records.

[0048] For example, the preprocessed data can be divided into a first data subset corresponding to a first brightness state and a second data subset corresponding to a second brightness state, where the brightness of the first brightness state is stronger than that of the second brightness state. The first sub-control curve applicable to the first brightness state is updated based on the first data subset; the second sub-control curve applicable to the second brightness state is updated based on the second data subset.

[0049] Unlike the data subset division described above, the preprocessed data can be divided into a third data subset corresponding to workdays and a fourth data subset corresponding to non-workdays. Then, based on the third data subset, the third sub-control curve used for workdays is updated; and based on the fourth data subset, the fourth control data used for non-workdays is updated.

[0050] It should be understood that updating a sub-control curve using a subset of data also involves fitting multiple sets of smoke concentrations and adjusted fan airflow within the subset of data to obtain a new sub-control curve. Further details will not be elaborated here.

[0051] In this embodiment of the invention, step S103 is also included: during the operation of the range hood, the fan air volume of the range hood is adjusted based on the adjustment control data so that the fan air volume follows the change of smoke concentration in the current environment of the range hood.

[0052] It should be understood that multiple operating modes can be pre-configured, such as manual adjustment mode, automatic adjustment mode, and hybrid adjustment mode. After the range hood enters automatic or hybrid adjustment mode, during its operation, it monitors the actual smoke concentration and the actual airflow of the surrounding environment. It compares the actual airflow with a target airflow, where the target airflow is the airflow value corresponding to the actual smoke concentration in the control data. If the actual airflow differs from the target airflow, the range hood's fan airflow is adjusted to the target airflow. If the actual airflow matches the target airflow, the fan airflow remains unchanged. This achieves automatic adjustment of the range hood's fan airflow according to the actual smoke concentration in the surrounding environment, thereby reducing the need for manual adjustment by the user.

[0053] It should be noted that the execution of steps S101 to S102 is independent of the execution of step S103, and there is no sequential order between them.

[0054] It should be understood that if the adjustment control data includes multiple different sub-control curves, then step S103 includes: determining the target sub-control curve corresponding to the current moment from the multiple sub-control curves, and adjusting the fan volume of the range hood according to the determined target sub-control curve, so that the fan volume of the range hood follows the change in smoke concentration in the current environment of the range hood. This achieves linear airflow control based on individual user needs, making it more precise.

[0055] Below, taking the adjustment control data, including a first sub-control curve corresponding to a first brightness state and a second sub-control curve corresponding to a second brightness state, as an example, the brightness state of the current environment where the range hood is located can be detected; based on the brightness state, either the first sub-control curve or the second sub-control curve is determined as the target sub-control curve. Specifically, if the current brightness state of the environment is the first brightness state, the first sub-control curve is selected as the target sub-control curve; otherwise, if the current brightness state of the environment is the second brightness state, the second sub-control curve is selected as the target sub-control curve.

[0056] It should be understood that adjusting the range hood's fan airflow according to the determined target sub-control curve involves: monitoring the actual smoke concentration in the current environment where the range hood is located and the current actual airflow of the range hood; comparing the current actual airflow with the second target airflow, where the second target airflow is the airflow value corresponding to the actual smoke concentration in the target sub-control curve; if the current actual airflow is different from the second target airflow, adjusting the range hood's fan airflow to the second target airflow; if the current actual airflow is the same as the second target airflow, keeping the range hood's fan airflow unchanged.

[0057] This invention updates the range hood's adjustment and control data based on the user's manual adjustment data over historical periods, thereby updating the relationship between smoke concentration and fan airflow. This allows the range hood's fan airflow to follow changes in the smoke concentration of the current environment, better meeting the user's subjective perception of smoke and fumes during cooking. Therefore, it is more accurate and satisfies the personalized and subjective smoke-free needs of different users.

[0058] Based on the same inventive concept, embodiments of the present invention provide a range hood adjustment and control device, see reference. Figure 2 As shown, it includes:

[0064] It is understood that, in some implementations, the determining sub-unit is specifically used for: detecting the light level of the current environment in which the range hood is located; and determining the first sub-control curve or the second sub-control curve as the target sub-control curve based on the light level.

The method as described in claim 5, characterized in that, The step of updating the adjustment and control data based on the preprocessed data includes: The preprocessed data is divided into multiple data subsets that correspond one-to-one with the multiple sub-control curves; The multiple sub-control curves are updated one-to-one based on the multiple data subsets.

7. The method as described in claim 5, characterized in that, The manual adjustment data includes multiple data records, and each data record includes the smoke concentration when the user manually adjusts the fan speed of the range hood once, and the fan volume after adjustment. The preprocessing of the manual adjustment data includes: Obtain the scene data of the range hood; Based on the scenario data, each data record in the manually adjusted data is enhanced to obtain enhanced adjustment data; Each data record in the enhanced adjustment data is classified and labeled to form the preprocessed data.

8. The method as described in claim 7, characterized in that, The classification and labeling of each data record in the enhanced adjustment data includes: If no change in fan airflow occurs based on the aforementioned adjustment and control data, and if any manual adjustment operation by the user is detected, a first data record is generated, and a classification mark for omission detection is made for the first data record. Within a preset time period for adjusting the fan air volume based on the adjustment control data, if a user's first manual adjustment operation is obtained, a second data record is generated, and a misjudgment classification mark is made for the second data record. The fan air volume adjusted based on the first manual adjustment operation is the same as the fan air volume adjusted based on the adjustment control data, but in the opposite direction. Within a preset time period for adjusting the fan air volume based on the adjustment control data, if a second manual adjustment operation by the user is obtained, a third data record is generated, and a classification mark is made for the third data record indicating whether the single air volume adjustment is correct or incorrect. The fan air volume adjusted based on the second manual adjustment operation is different from the fan air volume adjusted based on the adjustment control data.

9. A range hood adjustment and control device, characterized in that, include: The data acquisition unit is used to acquire the user's manual adjustment data for the range hood. The manual adjustment data includes the smoke concentration and the fan air volume after adjustment when the user manually adjusts the fan speed within the target historical period.
