These are described in detail below.

[0082] In order to better understand the range hood adaptive control method and device and range hood applied to cooking scenes described in the present invention, firstly, a home scene to which the range hood adaptive control method applied to cooking scenes is applicable is described. Specifically, the scene diagram of the home scene can be as follows: Figure 1 As shown, Figure 1 Schematic diagram of a scenario to which a range hood adaptive control method for a cooking scenario disclosed in an embodiment of the present invention is applicable.

[0084] Example 1

[0085] See also Figure 2 , Figure 2 This is a flow chart of a range hood adaptive control method for a cooking scene disclosed in an embodiment of the present invention. Figure 2 The described range hood adaptive control method applied to cooking scenes can be applied to a range hood control device, wherein the device may include a control device or a control server, wherein the control server may include a cloud server or a local server, which is not limited in the embodiment of the present invention. Figure 2 As shown, the range hood adaptive control method applied to a cooking scene may include the following operations:

[0086] 101. The range hood control device obtains target scene parameters corresponding to the cooking scene.

[0087] In an embodiment of the present invention, the target scene parameters optionally include at least current temperature-related parameters. Optionally, the current temperature-related parameters include at least the current temperature value corresponding to the cooking area of ​​the cooking scene; or, the current temperature-related parameters include at least the current temperature value corresponding to the cooking area and also include temperature changes corresponding to the cooking area, which is not limited in this embodiment of the present invention.

[0088] In an embodiment of the present invention, a range hood control device is optionally used to control the range hood in a cooking scene. The range hood is equipped with one or more sensors (e.g., infrared sensors), each of which can be electrically connected to the range hood so that the range hood can receive data transmitted by each sensor. The range hood control device can be integrated into the range hood or exist independently of the range hood. Specifically, if the range hood control device is integrated into the range hood (i.e., the range hood includes a built-in range hood control device, such as a microprocessor), communication between the range hood control device and the range hood sensors can be achieved through an electrical connection between the range hood sensors and the range hood control device. If the range hood control device exists independently of the range hood, communication between the range hood control device and the range hood sensors can be achieved through a communication module provided by the range hood and a communication module provided by the range hood control device. This communication between the range hood control device and the range hood sensors enables the range hood control device to obtain target scene parameters corresponding to the cooking scene. Optionally, the range hood communication module and the communication module of the range hood control device can include a WiFi module or a Bluetooth module, which is not limited in this embodiment of the present invention.

[0089] In the embodiment of the present invention, if the current temperature-related parameters of step 101 meet the preset parameter conditions, step 102 is triggered; if the current temperature-related parameters of step 101 meet the preset parameter conditions, the process can be terminated.

[0090] In an embodiment of the present invention, optionally, a preset parameter condition can be used to indicate that the current temperature-related parameters meet the conditions for range hood control, specifically, it can be: the condition that the current temperature value contained in the current temperature-related parameters reaches the preset temperature threshold, or the condition that the temperature change contained in the current temperature-related parameters meets the preset temperature change, or the composite condition that the current temperature value reaches the preset temperature threshold and the temperature change meets the preset temperature change. The embodiment of the present invention does not limit this.

[0091] 102. The range hood control device executes the matching range hood control operation.

[0092] In the embodiment of the present invention, specifically, the range hood control device controls the range hood to start up and controls the range hood to enter the smoke exhaust mode to exhaust the oil smoke and / or water vapor in the cooking scene, or the range hood air device adaptively adjusts the range hood operating parameters.

[0093] It can be seen that implementation Figure 2The described range hood adaptive control method applied to cooking scenes can obtain corresponding target scene parameters in the cooking scene, such as current temperature-related parameters, through the range hood control device. If the current temperature-related parameters meet the preset parameter conditions, the matching range hood control operation is executed. By providing an automatic control process for the range hood, the control operation of the range hood can be accurately and efficiently realized, which is conducive to improving the control convenience and timeliness of the range hood, that is, it is conducive to improving the control efficiency of the range hood. The automated range hood control process is conducive to improving the intelligence level of controlling the range hood, and is also conducive to improving the user experience and stickiness of using the range hood. At the same time, compared with the traditional range hood and stove linkage solution, this solution does not set a specific heating appliance, that is, no matter whether it is an electric rice cooker, induction cooker, oven, or even an electric kettle, as long as the current temperature-related parameters meet the preset parameter conditions, the parameter control of the cooking scene can be realized through the range hood control operation, which is conducive to improving the applicability of the range hood automatic control process.

[0094] In an optional embodiment, the method may further include:

[0095] The range hood control device determines whether the current temperature-related parameters meet the preset parameter conditions, and when it is determined that the current temperature-related parameters meet the preset parameter conditions, the range hood control device is triggered to execute step 102 to perform a matching range hood control operation;

[0096] The range hood control device determines whether the current temperature-related parameters meet the preset parameter conditions, which may include:

[0097] The range hood control device determines whether the current temperature value is greater than or equal to a preset temperature threshold based on the current temperature value corresponding to the cooking area included in the current temperature-related parameters;

[0098] When it is determined that the current temperature value is greater than or equal to the temperature threshold, the range hood control device determines that the current temperature-related parameters meet the preset parameter conditions;

[0099] When it is determined that the current temperature value is less than the preset temperature threshold, the range hood control device determines that the current temperature-related parameters do not meet the preset parameter conditions; or,

[0100] When it is determined that the current temperature value is less than the temperature threshold, the range hood control device determines whether the temperature change conforms to the preset expected temperature change according to the temperature change corresponding to the cooking area included in the current temperature-related parameters;

[0101] When it is determined that the temperature change is consistent with the expected temperature change, the range hood control device determines that the current temperature-related parameters meet the preset parameter conditions; and when it is determined that the temperature change is not consistent with the expected temperature change, it determines that the current temperature-related parameters do not meet the preset parameter conditions.

[0102] In an embodiment of the present invention, specifically, when the current temperature value in the cooking scene is greater than or equal to a preset temperature threshold, or the temperature change in the cooking scene meets the preset expected temperature change, it is determined that the current temperature-related parameters meet the preset parameter conditions; when the current temperature value in the cooking scene is less than the preset temperature threshold, and the temperature change in the cooking scene does not meet the preset expected temperature change, it is determined that the current temperature-related parameters do not meet the preset parameter conditions.

[0103] It can be seen that this optional embodiment can flexibly and accurately determine whether the current temperature-related parameters meet the preset parameter conditions (i.e., the conditions for range hood control) through the range hood control device based on the current temperature value and / or temperature change contained in the current temperature-related parameters, which is beneficial to improving the accuracy and reliability of the judgment result of whether the current temperature-related parameters meet the preset parameter conditions, and only when it is determined that the current temperature-related parameters meet the preset parameter conditions, the matching range hood control operation is executed, which is beneficial to improving the triggering accuracy and reliability of the range hood control operation.

[0104] In this optional embodiment, as an optional implementation manner, the range hood control device determines whether the temperature change situation conforms to the preset expected temperature change situation based on the temperature change situation corresponding to the cooking area included in the current temperature-related parameters, which may include:

[0105] The range hood control device predicts the expected temperature change curve of the cooking area within a preset future time period based on the temperature change corresponding to the cooking area included in the current temperature-related parameters;

[0106] The range hood control device calculates the degree of fit between the expected temperature change curve and the preset standard temperature change curve, and obtains the curve fit corresponding to the expected temperature change curve;

[0107] The range hood control device determines whether the curve fit corresponding to the expected temperature change curve is greater than or equal to a preset fit;

[0108] When it is determined that the curve fit is greater than or equal to the preset fit, the range hood control device determines that the temperature change condition meets the preset expected temperature change condition;

[0109] When it is determined that the curve fit is less than the preset fit, the range hood control device determines that the temperature change does not conform to the preset expected temperature change.

[0110] In the embodiment of the present invention, the preset future time period can optionally be 1 minute, 90 seconds, or any other preset value. The preset fit degree can be 70%, 85%, or any other preset value, which is not limited in the embodiment of the present invention.

[0111] In the embodiment of the present invention, specifically, the standard temperature change curve can be determined by the following method:

[0112] The range hood control device obtains a plurality of historical cooking scenes stored in a preset database, each of which has a corresponding historical temperature value;

[0113] The range hood control device determines, from all historical cooking scenes, a historical cooking scene in which the historical temperature value is greater than or equal to a preset temperature threshold value as a reference cooking scene;

[0114] The range hood control device fits each reference cooking scene based on all temperature values ​​within the cooking time period corresponding to the reference cooking scene to obtain a historical temperature change curve for each reference cooking scene, wherein the start execution time of the range hood control operation for each reference cooking scene is within the historical time period;

[0115] The range hood control device determines the slope of each reference cooking scene within a preset time length at the start of the range hood control operation based on the historical temperature change curve of the reference cooking scene, and obtains a target slope corresponding to the reference cooking scene;

[0116] The range hood control device sorts all reference cooking scenes according to the target slopes of all reference cooking scenes to obtain a sorting result;

[0117] Based on the historical temperature change curves for all reference cooking scenarios and the aforementioned ranking results, the range hood control device selects the historical temperature change curve with the highest ranking among all the historical temperature change curves for the reference cooking scenarios as the standard temperature change curve. This allows the range hood control device to accurately determine the standard temperature change curve by processing the historical temperature-related parameters of the historical cooking scenarios that meet preset parameter conditions. This facilitates subsequent calculation of the fit between the expected temperature change curve corresponding to the current temperature-related parameters and the standard temperature change curve, and improves the matching between the determined standard temperature change curve and the range hood control device and the cooking scenario.

[0118] It can be seen that this optional embodiment can predict the expected temperature change curve of the cooking zone within a preset future time period through the range hood control device based on the temperature change corresponding to the cooking zone included in the current temperature-related parameters, and calculate the fit between the expected temperature change curve and the preset standard temperature change curve to obtain the curve fit corresponding to the expected temperature change curve, thereby improving the accuracy and reliability of the calculated fit between the expected temperature change curve and the preset standard temperature change curve. Subsequently, it is determined whether the curve fit corresponding to the expected temperature change curve is greater than or equal to the preset fit. When it is determined that the curve fit is greater than or equal to the preset fit, the range hood control device determines that the temperature change conforms to the preset expected temperature change, thereby improving the accuracy and reliability of determining that the temperature change conforms to the preset expected temperature change, which is conducive to improving the accuracy and timeliness of subsequently determining that the current temperature-related parameters meet the preset parameter conditions, thereby facilitating improving the accuracy and timeliness of triggering the range hood control operation. When it is determined that the curve fit is less than the preset fit, the range hood control device determines that the temperature change does not conform to the preset expected temperature change, thereby improving the accuracy and reliability of determining that the temperature change does not conform to the preset expected temperature change.

[0126] 204. Use the target operating parameters to replace the current operating parameters, and control the range hood to operate according to the target operating parameters.

[0127] In the embodiment of the present invention, for other descriptions of steps 201 to 204 , please refer to the detailed description of steps 101 to 102 in the first embodiment, which will not be repeated in the embodiment of the present invention.

[0128] It can be seen that implementation Figure 3 The described adaptive range hood control method for cooking scenarios enables the range hood control device to obtain target scenario parameters corresponding to the cooking scenario, such as current temperature-related parameters. If the current temperature-related parameters meet preset parameter conditions, the corresponding range hood control operation is executed. This provides an automatic range hood control process, accurately and efficiently implementing range hood control operations, thereby improving the convenience and timeliness of range hood control, that is, improving range hood control efficiency. Furthermore, the automated range hood control process enhances the intelligent control level of the range hood, and also improves the user experience and stickiness of the range hood. Furthermore, compared to traditional range hood and stove linkage solutions, this solution does not specify a specific heating appliance. That is, whether it is an electric rice cooker, induction cooker, oven, or even an electric kettle, as long as the current temperature-related parameters meet preset parameter conditions, the range hood control operation can achieve parameter control of the cooking scenario, thereby improving the applicability of the range hood automatic control process. Furthermore, the range hood control device can also control the range hood to start and exhaust, or adaptively adjust the range hood operating parameters to achieve range hood control operations, thereby increasing the diversity and flexibility of range hood control operations.

[0129] In an optional embodiment, the range hood control device in step 203 adjusts the acquired current operating parameters of the range hood to obtain target operating parameters, which may include:

[0130] The range hood control device obtains the current operating parameters of the range hood; and based on the current temperature-related parameters and the preset parameter conditions, analyzes the triggering factors in the target scene parameters that trigger the current temperature-related parameters to meet the preset parameter conditions;

[0131] The range hood control device generates range hood control parameters of the range hood controlled by the range hood control device based on the trigger factor, and the range hood control parameters are used to control the operating parameters of the range hood;

[0132] The range hood control device adjusts the current operating parameters according to the range hood control parameters to obtain the target operating parameters.

[0133] In an embodiment of the present invention, the target scene parameters also include cooking scene fume-related parameters and cooking scene water vapor-related parameters. Specifically, the trigger factor for the current temperature-related parameter to meet the preset parameter condition may include: the fume gas concentration corresponding to the fume-related parameter, or the scene humidity corresponding to the water vapor-related parameter. When the trigger factor includes fume gas concentration, it indicates that the fume gas concentration triggers the current temperature-related parameter to meet the preset parameter condition; when the trigger factor includes scene humidity, it indicates that the scene humidity triggers the current temperature-related parameter to meet the preset parameter condition.

[0134] It can be seen that this optional embodiment can obtain the current working parameters of the range hood through the range hood control device; and according to the current temperature-related parameters and the preset parameter conditions, analyze the trigger factors in the target scene parameters that trigger the current temperature-related parameters to meet the preset parameter conditions, which can improve the analysis accuracy and efficiency of the trigger factors that cause the current temperature-related parameters to meet the preset parameter conditions, and then generate the range hood control parameters of the range hood controlled by the range hood control device based on the trigger factors, which can improve the generation accuracy and efficiency of the range hood control parameters based on the trigger factors, and then adjust the current working parameters according to the range hood control parameters to obtain the target working parameters, which can improve the adjustment accuracy and reliability of the range hood working parameters, thereby helping to improve the control accuracy and reliability of the range hood.

[0135] In this optional embodiment, as an optional implementation manner, the range hood control device generates range hood control parameters of the range hood controlled by the range hood control device based on the trigger factor, which may include:

[0136] The range hood control device determines, based on the trigger factor, a target wind speed level that matches the trigger factor from all wind speed levels of the range hood controlled by the range hood control device;

[0137] The range hood control device generates range hood control parameters according to the target wind speed gear.

[0138] In an embodiment of the present invention, the range hood control device specifically determines the target wind speed, target air volume, and target air pressure values ​​included in the target wind speed level as the range hood parameter control requirements. Based on the obtained current control parameters of the range hood and the aforementioned parameter control requirements, the range hood control device generates a range hood control coefficient for the current control parameters. Based on the range hood control coefficient, the current control parameters are adjusted to obtain the range hood control parameters. Determining the target wind speed level based on the trigger factor in this way helps improve the accuracy and reliability of generating the range hood control parameters.

[0139] It can be seen that this optional implementation method can determine the target wind speed gear that matches the trigger factor from all wind speed gears of the range hood controlled by the range hood control device based on the trigger factor through the range hood control device, thereby improving the matching accuracy and efficiency of the trigger factor and the wind speed gear, and is conducive to improving the accuracy and reliability of matching the target wind speed gear. Subsequently, the range hood control parameters of the range hood are generated according to the target wind speed gear, thereby improving the accuracy and reliability of the generation of the range hood control parameters, and facilitating the subsequent adjustment of the range hood working parameters.

[0140] In this optional embodiment, the range hood control device may optionally determine, based on the trigger factor, a target wind speed level that matches the trigger factor from all wind speed levels of the range hood controlled by the range hood control device, which may include:

[0141] When the trigger factor includes the oil fume concentration, the range hood control device determines the target oil fume concentration range of the oil fume concentration based on the oil fume concentration and at least one preset oil fume concentration range, each oil fume concentration range corresponds to a wind speed gear; and determines the wind speed gear corresponding to the target oil fume concentration range as the target wind speed gear matching the oil fume concentration; or,

[0142] When the trigger factor includes the scene humidity, the range hood control device determines the highest wind speed gear among all wind speed gears as the target wind speed gear that matches the scene humidity.

[0143] For example, all preset oil smoke concentration intervals may include a first oil smoke concentration interval, a second oil smoke concentration interval, and a third oil smoke concentration interval, wherein the interval maximum value of the first oil smoke concentration interval is less than the interval minimum value of the second oil smoke concentration interval, and the interval maximum value of the second oil smoke concentration interval is less than the interval maximum value of the third oil smoke concentration interval. Optionally, the wind speed gear corresponding to the first oil smoke concentration interval can be set to a low speed gear, the wind speed gear corresponding to the second oil smoke concentration interval can be set to a medium speed gear, and the wind speed gear corresponding to the third oil smoke concentration interval can be set to a high speed gear. Similarly, when the wind speed gear of the range hood also includes an ultra-high speed gear whose gear-related parameter values ​​are higher than the gear-related parameter values ​​corresponding to the high speed gear (for example, the wind speed value, air volume value, and wind pressure value of the ultra-high speed gear are all greater than the corresponding values ​​of the high speed gear), a fourth oil smoke concentration whose interval minimum value is greater than the interval maximum value of the third oil smoke concentration can be set, and the wind speed gear corresponding to the fourth oil smoke concentration is set to an ultra-high speed gear, which is not limited in the embodiment of the present invention.

[0144] It can be seen that this optional implementation scheme can also determine the target oil fume concentration range in which the oil fume concentration is located according to the oil fume concentration and at least one preset oil fume concentration range through the range hood control device when the trigger factor includes the oil fume concentration; and determine the wind speed gear corresponding to the target oil fume concentration range as the target wind speed gear that matches the oil fume concentration, which can improve the accuracy and reliability of determining the target wind speed gear based on the oil fume concentration range when the temperature rises due to excessive oil fume, and directly determine the highest wind speed gear among all wind speed gears as the target wind speed gear that matches the scene humidity when the trigger factor includes the scene humidity, which can improve the speed and efficiency of determining the target wind speed gear based on the highest wind speed gear when the temperature rises due to excessive water vapor.

[0147] The acquisition module 301 is used to acquire target scene parameters corresponding to the cooking scene, where the target scene parameters at least include current temperature-related parameters.

[0148] The control module 302 is configured to execute a matching range hood control operation if the current temperature-related parameters meet preset parameter conditions.

[0149] It can be seen that implementation Figure 4 The described range hood control device can obtain the corresponding target scene parameters in the cooking scene through the range hood control device, such as the current temperature-related parameters. If the current temperature-related parameters meet the preset parameter conditions, the matching range hood control operation is executed. By providing an automatic control process for the range hood, the control operation of the range hood can be accurately and efficiently realized, which is conducive to improving the control convenience and timeliness of the range hood, that is, it is conducive to improving the control efficiency of the range hood. The automated range hood control process is conducive to improving the intelligence level of controlling the range hood, and is also conducive to improving the user experience and stickiness of the range hood. At the same time, compared with the traditional range hood and stove linkage solution, this solution does not set a specific heating appliance, that is, no matter whether it is an electric rice cooker, induction cooker, oven, or even an electric kettle, as long as the current temperature-related parameters meet the preset parameter conditions, the parameter control of the cooking scene can be achieved through the range hood control operation, which is conducive to improving the applicability of the range hood automatic control process.

[0150] In an optional embodiment, the control module 302 may execute the matching range hood control operation in the following manner:

[0151] Execute a power-on control operation on the range hood controlled by the range hood control device, and control the range hood to enter the smoke exhaust mode; or,

[0152] The obtained current operating parameters of the range hood are adjusted to obtain target operating parameters, and the target operating parameters are used to replace the current operating parameters to control the range hood to operate according to the target operating parameters.

[0153] It can be seen that this optional embodiment can control the range hood to start and exhaust smoke through the range hood control device, or adaptively adjust the range hood operating parameters to achieve control operations on the range hood, which is conducive to improving the diversity and flexibility of the range hood control operations.

[0155] Obtain the current operating parameters of the range hood; and based on the current temperature-related parameters and preset parameter conditions, analyze the trigger factors in the target scene parameters that trigger the current temperature-related parameters to meet the preset parameter conditions. The target scene parameters also include the oil fume-related parameters of the cooking scene and the water vapor-related parameters of the cooking scene;

[0156] Based on the trigger factor, generating range hood control parameters of the range hood controlled by the range hood control device, the range hood control parameters being used to control the operating parameters of the range hood;

[0157] According to the range hood control parameters, the current operating parameters are adjusted to obtain the target operating parameters.

[0158] It can be seen that this optional implementation method can obtain the current working parameters of the range hood through the range hood control device; and according to the current temperature-related parameters and the preset parameter conditions, analyze the trigger factors in the target scene parameters that trigger the current temperature-related parameters to meet the preset parameter conditions, which can improve the analysis accuracy and efficiency of the trigger factors that cause the current temperature-related parameters to meet the preset parameter conditions, and then generate the range hood control parameters of the range hood controlled by the range hood control device based on the trigger factors, which can improve the generation accuracy and efficiency of the range hood control parameters based on the trigger factors, and then adjust the current working parameters according to the range hood control parameters to obtain the target working parameters, which can improve the adjustment accuracy and reliability of the range hood working parameters, thereby helping to improve the control accuracy and reliability of the range hood.

[0159] In this optional embodiment, the control module 302 may generate the range hood control parameters of the range hood controlled by the range hood control device based on the triggering factor in the following manner:

[0160] Based on the trigger factor, a target wind speed level that matches the trigger factor is determined from all wind speed levels of the range hood controlled by the range hood control device. The trigger factor includes the oil fume concentration corresponding to the oil fume-related parameter or the scene humidity corresponding to the water vapor-related parameter.

[0161] Generate range hood control parameters based on the target wind speed level.

[0162] It can be seen that this optional implementation method can also determine the target wind speed gear that matches the trigger factor from all wind speed gears of the range hood controlled by the range hood control device based on the trigger factor through the range hood control device, thereby improving the matching accuracy and efficiency of the trigger factor and the wind speed gear, and is conducive to improving the accuracy and reliability of matching the target wind speed gear. Subsequently, the range hood control parameters of the range hood are generated according to the target wind speed gear, thereby improving the accuracy and reliability of the generation of the range hood control parameters, and facilitating the subsequent adjustment of the range hood working parameters.

[0163] In this optional embodiment, further optionally, the control module 302 may determine, based on the trigger factor, a target wind speed level that matches the trigger factor from all wind speed levels of the range hood controlled by the range hood control device. Specifically, the method may include:

[0164] When the trigger factor includes the oil fume concentration, the target oil fume concentration range is determined based on the oil fume concentration and at least one preset oil fume concentration range, and each oil fume concentration range corresponds to a wind speed gear; and the wind speed gear corresponding to the target oil fume concentration range is determined as the target wind speed gear matching the oil fume concentration; or

[0165] When the trigger factor includes scene humidity, the highest wind speed level among all wind speed levels is determined as the target wind speed level that matches the scene humidity.

[0166] It can be seen that this optional implementation scheme can also determine the target oil fume concentration range in which the oil fume concentration is located according to the oil fume concentration and at least one preset oil fume concentration range through the range hood control device when the trigger factor includes the oil fume concentration; and determine the wind speed gear corresponding to the target oil fume concentration range as the target wind speed gear that matches the oil fume concentration, which can improve the accuracy and reliability of determining the target wind speed gear based on the oil fume concentration range when the temperature rises due to excessive oil fume, and directly determine the highest wind speed gear among all wind speed gears as the target wind speed gear that matches the scene humidity when the trigger factor includes the scene humidity, which can improve the speed and efficiency of determining the target wind speed gear based on the highest wind speed gear when the temperature rises due to excessive water vapor.

[0167] In another optional embodiment, the current temperature-related parameters include at least the current temperature value corresponding to the cooking area of ​​the cooking scene; or, the current temperature-related parameters include at least the current temperature value corresponding to the cooking area and also include the temperature change of the cooking area. Figure 5 As shown, Figure 5 Schematic diagram of another smoke machine control device disclosed in an embodiment of the present invention. Figure 5 As shown, the device may further include:

[0168] The judgment module 303 is used to judge whether the current temperature value is greater than or equal to a preset temperature threshold according to the current temperature value corresponding to the cooking area included in the current temperature-related parameters.

[0169] The determination module 304 is configured to determine whether the current temperature-related parameters meet the preset parameter conditions when the judgment module 303 determines that the current temperature value is greater than or equal to the temperature threshold.

[0170] The determination module 304 is further configured to determine that the current temperature-related parameters do not meet the preset parameter conditions when the judgment module 303 determines that the current temperature value is less than the preset temperature threshold.

[0171] The judgment module 303 is further configured to judge whether the temperature change conforms to a preset expected temperature change according to the temperature change corresponding to the cooking area included in the current temperature-related parameters when it is determined that the current temperature value is less than the temperature threshold.

[0172] The determination module 304 is also used to determine that the current temperature-related parameters meet the preset parameter conditions when the judgment module 303 determines that the temperature change situation meets the expected temperature change situation; and when the judgment module 303 determines that the temperature change situation does not meet the expected temperature change situation, determine that the current temperature-related parameters do not meet the preset parameter conditions.

[0173] It can be seen that this optional embodiment can flexibly and accurately determine whether the current temperature-related parameters meet the preset parameter conditions (i.e., the conditions for range hood control) through the range hood control device based on the current temperature value and / or temperature change contained in the current temperature-related parameters, which is beneficial to improving the accuracy and reliability of the judgment result of whether the current temperature-related parameters meet the preset parameter conditions, and only when it is determined that the current temperature-related parameters meet the preset parameter conditions, the matching range hood control operation is executed, which is beneficial to improving the triggering accuracy and reliability of the range hood control operation.

[0174] In this optional embodiment, as an optional implementation manner, the judgment module 303 judges whether the temperature change situation meets the preset expected temperature change situation based on the temperature change situation corresponding to the cooking zone included in the current temperature-related parameters, and specifically includes:

[0175] Predicting an expected temperature change curve of the cooking area within a preset future time period based on the temperature change corresponding to the cooking area included in the current temperature-related parameters;

[0176] Calculating the degree of fit between the expected temperature change curve and the preset standard temperature change curve to obtain the curve fit corresponding to the expected temperature change curve;

[0177] Determine whether the curve fit corresponding to the expected temperature change curve is greater than or equal to a preset fit;

[0179] When it is determined that the curve fit is less than the preset fit, it is determined that the temperature change does not conform to the preset expected temperature change.

[0180] It can be seen that this optional embodiment can predict the expected temperature change curve of the cooking zone within a preset future time period through the range hood control device based on the temperature change corresponding to the cooking zone included in the current temperature-related parameters, and calculate the fit between the expected temperature change curve and the preset standard temperature change curve to obtain the curve fit corresponding to the expected temperature change curve, thereby improving the accuracy and reliability of the calculated fit between the expected temperature change curve and the preset standard temperature change curve. Subsequently, it is determined whether the curve fit corresponding to the expected temperature change curve is greater than or equal to the preset fit. When it is determined that the curve fit is greater than or equal to the preset fit, the range hood control device determines that the temperature change conforms to the preset expected temperature change, thereby improving the accuracy and reliability of determining that the temperature change conforms to the preset expected temperature change, which is conducive to improving the accuracy and timeliness of subsequently determining that the current temperature-related parameters meet the preset parameter conditions, thereby facilitating improving the accuracy and timeliness of triggering the range hood control operation. When it is determined that the curve fit is less than the preset fit, the range hood control device determines that the temperature change does not conform to the preset expected temperature change, thereby improving the accuracy and reliability of determining that the temperature change does not conform to the preset expected temperature change.
