Figure 2 This is a side view structural diagram of a kitchen appliance provided in an embodiment of the present invention. Figure 3 This is a schematic diagram of the structure of a temperature detection module provided in an embodiment of the present invention. Figure 4 This is a flowchart illustrating a control method for kitchen appliances provided in an embodiment of the present invention. This embodiment is applicable to the cooking process of a user using a stove and a range hood. The control method can be executed by a control device for the kitchen appliance, which can be implemented in software and / or hardware, and can be configured in a control board. Figure 1 , Figure 2 and Figure 3As shown, the kitchen appliance includes a cooktop 10 and a range hood 20 located above the cooktop 10. A temperature detection module 30 is installed on the side of the range hood 20 facing the cooktop 10. The temperature detection module 30 includes a temperature probe 31 and a steering mechanism 32. The steering mechanism 32 is used to adjust the center orientation of the temperature probe 31. Figure 4 As shown, the control method includes:
[0071] S110. Use the steering mechanism to calibrate the center of the temperature probe to the center of the stove or cookware.
[0072] Specifically, please refer to Figure 1 , Figure 2 and Figure 3 The kitchen appliance includes a cooktop 10 and a range hood 20 located above the cooktop 10. A temperature detection module 30 is installed on the side of the range hood 20 facing the cooktop 10. The temperature detection module 30 includes a temperature probe 31 and a steering mechanism 32. The temperature probe 31 can detect temperature data in the area it faces, and the steering mechanism 32 can adjust the center orientation of the temperature probe 31 so that it can detect temperature data at various points within the area of the cooktop 10. It should be noted that the temperature sensing angle of the temperature probe 31 is conical, meaning it can detect temperature data within a conical area. The center of the temperature probe 31 is the central axis of this conical area, making temperature data detection more accurate. By adjusting the center orientation of the temperature probe 31 using the steering mechanism 32 until it aligns with the center of the burner or cookware, the temperature data at the center of the burner or cookware is used as the temperature data for the entire area of the cooktop 10. At this point, the temperature probe 31 can detect the temperature data during the use of the cooktop 10.
[0073] S120: Real-time acquisition of the temperature at the center of the burner or pot when the stove is on.
[0074] Specifically, please refer to Figure 1 , Figure 2 and Figure 3 When the center of the temperature probe 31 is facing the center of the burner or the pot, the temperature probe 31 can collect the temperature of the center of the burner or the pot in real time when the stove 10 is on. For example, when the stove 10 is off, the temperature probe 31 detects a significant temperature change at the center of the burner or the pot, that is, the stove 10 is successfully ignited. When the stove 10 is on, the temperature probe 31 detects a significant temperature change at the center of the burner or the pot, that is, the user changes the cooking process or cooking steps.
[0075] S130. Determine the current cooking type based on the temperature of the center position of the burner or pot when the stove is turned on, as collected in real time.
[0076] Specifically, please refer to Figure 1 , Figure 2 and Figure 3 The range hood 20 includes a controller, an arithmetic logic unit (ALU), and a memory. Figure 1 and Figure 2 The controller, arithmetic logic unit (ALU), and memory are not shown in the diagram; however, they may be integrated into a control board inside the range hood 20. The memory stores temperature data models for various cooking states throughout the entire cooking process of the cooktop 10. For example, the temperature data models may include non-working temperature ranges, successful ignition temperature thresholds, and temperature ranges for stir-frying and stewing. This kitchen appliance can determine the cooking state corresponding to the temperature at the center of the burner or pot when the cooktop 10 is on, based on real-time collected temperature data and the temperature data models stored in the memory. This determines the current cooking type; for example, the cooking state may be a no-pot state, stir-fry state, soup-making state, or hot oil state.
[0077] S140. Adjust the airflow of the range hood according to the current cooking type.
[0078] Specifically, please refer to Figure 1 , Figure 2 and Figure 3 The range hood 20 also includes a smoke baffle 21, a moving part of the range hood 20. When open, the smoke baffle 21 forms an angle with the air inlet of the main unit of the range hood 20 to collect smoke. When closed, the surface of the smoke baffle 21 is easier to clean, and the overall design of the range hood 20 is more streamlined. This kitchen appliance can adjust the airflow of the range hood 20 according to the current cooking type. For example, when the current cooking type is stir-frying, the airflow of the range hood 20 should be adjusted to a high airflow, and when the current cooking type is stewing, the airflow of the range hood 20 should be adjusted to a low airflow. During the user's cooking process using the stove 10, the range hood 20 can adjust its airflow according to the changes in the user's cooking status, without requiring the user to manually adjust the airflow or turn it on and off, which is conducive to realizing the intelligent use of this kitchen appliance.
[0079] The technical solution in this embodiment of the invention includes a kitchen appliance comprising a cooktop and a range hood located above the cooktop. A temperature detection module is installed on the side of the range hood facing the cooktop. The temperature detection module includes a temperature probe and a steering mechanism, the steering mechanism being used to adjust the center orientation of the temperature probe. The control method includes: using the steering mechanism to calibrate the center orientation of the temperature probe to the center position of the burner or cookware; real-time acquisition of the temperature at the center position of the burner or cookware when the cooktop is on; determining the current cooking type based on the real-time acquired temperature at the center position of the burner or cookware when the cooktop is on; and adjusting the airflow of the range hood according to the current cooking type. This control method utilizes the intelligent adjustability of the temperature probe's center orientation, automatically calibrating and adjusting the center orientation of the temperature probe to the center position of the burner or cookware based on the user environment and installation dimensions. This avoids the problem of temperature detection data deviation caused by installation positional deviations, which is beneficial to improving the temperature detection accuracy of the temperature detection module. The range hood's operating process adjustment based on the temperature detection response is more consistent with the actual cooking state, improving the intelligence of the kitchen appliance and enhancing the user's cooking experience.
[0080] Figure 5 This is a flowchart illustrating another control method for kitchen appliances provided in this embodiment of the invention. This embodiment is an optimization based on the above embodiment. Optionally, a steering mechanism is used to calibrate the center orientation of the temperature probe to the center position of the stove or cookware, including:
[0081] When the stove is on, the steering mechanism drives the temperature probe to rotate and collects the temperature in real time.
[0082] The center position of the stove or cookware is determined based on the real-time temperature distribution data.
[0083] The temperature probe is driven to align with the center of the stove or cookware by a steering mechanism.
[0084] For details not covered in this embodiment, please refer to the above embodiments. Figure 5 As shown, the control method includes:
[0085] S210. When the stove is on, control the steering mechanism to drive the temperature probe to rotate and collect the temperature in real time.
[0086] Optionally, continue to refer to Figure 1 , Figure 2 and Figure 3The steering mechanism 32 includes a housing 321 and two telescopic rods 322. The temperature probe 31 is universally hinged to the inner wall of the housing 321. The two telescopic rods 322 extend and retract along the first direction X and the second direction Y, respectively. The first direction X and the second direction Y intersect. The two ends of the telescopic rods 322 are connected to the temperature probe 31 and the inner wall of the housing 321, respectively, and at least one end is connected by a universal hinge. Specifically, the steering mechanism 32 includes a housing 321 (the housing 321 includes a top cover 3211 and a base 3212) and two telescopic rods 322. The temperature probe 31 is universally hinged to the inner wall of the top cover 3211 through the probe bottom 323. The base 3212 is a hollow structure and is sealed to the top cover 3211. The two ends of the telescopic rods 322 are respectively connected to the temperature probe 31 and the inner wall of the housing 321, and at least one end is connected in a universal hinge manner. The temperature probe 31 and the two telescopic rods 322 are all located inside the housing 321. A filter glass 324 is provided on the side of the housing 321 facing the stove 10. There is a gap between the filter glass 324 and the temperature probe 31 to facilitate the movement of the temperature probe 31. For example, the universal hinge method can adopt universal ball joints and ring buckles, etc. The two telescopic rods 322 extend and retract along the first direction X and the second direction Y, respectively. For example, the two telescopic rods 322 can be driven by a micro motor, and the two telescopic rods 322 can be made of lead screws and gear racks, etc., and the first direction X and the second direction Y intersect. Then the extension and retraction of the two telescopic rods 322 can drive the temperature probe 31 to detect the temperature data at various points on the two-dimensional plane where the stove 10 is located.
[0087] Optionally, continue to refer to Figure 1 , Figure 2 and Figure 3 When the stove 10 is turned on, the steering mechanism 32 is controlled to drive the temperature probe 31 to rotate and collect the temperature in real time. This includes: when the stove 10 is turned on, controlling the two telescopic rods 322 to extend and retract along the first direction X and the second direction Y respectively, so as to drive the center of the temperature probe 31 to move along the first direction X and the second direction Y respectively, and collect the temperature in real time.
[0088] Specifically, when the stove 10 is turned on, the two telescopic rods 322 are controlled to extend and retract along the first direction X and the second direction Y respectively. The two telescopic rods 322 can adjust the center orientation of the temperature probe 31. The extension and retraction of the two telescopic rods 322 can drive the temperature probe 31 to detect the temperature data at various points on the two-dimensional plane where the stove 10 is located, and collect the temperature data in real time.
[0089] S220. Determine the center position of the burner or cookware based on the real-time temperature distribution data.
[0090] Optionally, the center position of the burner or cookware can be determined based on the real-time temperature distribution data, including:
[0091] S2201. Determine the extreme temperature points in the first and second directions.
[0092] Specifically, Figure 6 This is a schematic diagram of an XOY coordinate system established on a two-dimensional plane where the stove is located, provided by an embodiment of the present invention. Figure 3 and Figure 6 As shown, an XOY coordinate system is established on the two-dimensional plane where the stove 10 is located, and the center of the temperature probe 31 is oriented towards the two-dimensional plane where the stove 10 is located. For example, the first direction X can be used as the X-axis, and the second direction Y as the Y-axis. The first direction X and the second direction Y intersect. By adjusting the extension and retraction of the two telescopic rods 322 and the temperature data (temperature distribution) collected in real time by the temperature probe 31, several temperature data points collected in real time are recorded in the first direction X and the second direction Y, respectively. The several temperature data points in the first direction X are used to form a temperature data curve, and the extreme temperature points in the first direction X are determined based on the temperature data curve. Similarly, several temperature data points in the second direction Y are used to form a temperature data curve, and the extreme temperature points in the second direction Y are determined based on the temperature data curve. It should be noted that... Figure 7A This is a temperature data curve in the first direction provided by an embodiment of the present invention when no pot is placed on the stove. Figure 7B This is a temperature data curve in the second direction provided by an embodiment of the present invention when no pot is placed on the stove, as shown in the figure. Figure 7A and Figure 7B As shown, when no pot is placed on the stove 10, the temperature data curves formed in the first direction X and the second direction Y respectively exhibit a shape that is high in the middle and low at both ends. Furthermore, the coordinates of the temperature maximum point of the temperature data curve in the first direction X are X... X The coordinates of the temperature maximum point of the temperature data curve in the second direction Y are Y Y ; Figure 8A This is a temperature data curve in a first direction when a pot is placed on a stove, as provided in an embodiment of the present invention; Figure 8B This is a temperature data curve in the second direction provided by an embodiment of the present invention when a pot is placed on a stove. Figure 8A and Figure 8B As shown, when a pot is placed on the stove 10, the temperature data curves formed in the first direction X and the second direction Y respectively exhibit a shape that is low in the middle and high at both ends. Furthermore, the coordinates of the temperature minimum point of the temperature data curve in the first direction X are X... X The coordinates of the temperature minimum point of the temperature data curve in the second direction Y are Y Y .
[0093] S2202. Using the coordinates of the extreme temperature points in the first and second directions respectively in the first and second directions as the center position of the stove or cookware, determine the center position of the stove or cookware.
[0094] Specifically, please refer to Figure 6 , Figure 7A and Figure 7B When no pot is placed on the stove 10, the temperature data curves formed in the first direction X and the second direction Y show a shape that is high in the middle and low at both ends. The coordinates of the temperature maximum point in the temperature data curve in the first direction X can be used as the coordinates of the center position of the burner in the first direction X; the coordinates of the temperature maximum point in the temperature data curve in the second direction Y can be used as the coordinates of the center position of the burner in the second direction Y. The coordinates of the center position of the burner in the first direction X are... X The center position of the stove head is located at the coordinate Y in the second direction. Y The two-dimensional coordinate point (X) on the two-dimensional plane where the stove 10 is located. X Y Y The two-dimensional coordinate point is the center position of the stove head.
[0095] Continue to refer to Figure 6 , Figure 8A and Figure 8B When a pot is placed on the stove 10, the temperature data curves formed in the first direction X and the second direction Y exhibit a shape that is low in the middle and high at both ends. The coordinates of the temperature minimum point in the first direction X temperature data curve can be used as the coordinates of the pot's center position in the first direction X; similarly, the coordinates of the temperature minimum point in the second direction Y temperature data curve can be used as the coordinates of the pot's center position in the second direction Y. The coordinates of the pot's center position in the first direction X are... X The center position of the cookware is located at the coordinate Y in the second direction. Y The two-dimensional coordinate point (X) on the two-dimensional plane where the stove 10 is located. X Y Y The two-dimensional coordinate point is the center of the cookware.
[0096] S230, the center of the temperature probe is driven to the center of the stove or cookware by the steering mechanism.
[0097] Specifically, optionally, please refer to [further details]. Figure 1 , Figure 2 , Figure 3 and Figure 6The position of the temperature probe 31 is moved by the extension and retraction of the two telescopic rods 322, so that the center of the temperature probe 31 faces the center of the stove or the pot. When the center of the temperature probe 31 is at the center of the stove or the pot, more accurate temperature data can be collected in real time. By comparing this temperature data with the temperature data model stored in the memory, the current cooking type can be better determined, which is more in line with the user's cooking status.

[0100] S260. Adjust the airflow of the range hood according to the current cooking type.
[0101] The technical solution in this embodiment of the invention details how to use a steering mechanism to calibrate the center of the temperature probe to the center of the burner or cookware. When the stove is on, the extension and retraction of two telescopic rods drives the temperature probe to rotate. The temperature probe detects temperature data at various points on the two-dimensional plane where the stove is located, and determines the center position of the burner or cookware based on the real-time temperature distribution. When the center of the temperature probe is at the center of the burner or cookware, more accurate temperature data can be collected in real time. By comparing this temperature data with the temperature data model stored in the memory, the current cooking type can be better determined, which is more in line with the user's cooking state.

This embodiment is an optimization based on the above embodiment. Optionally, a depth camera is integrated into the temperature probe, and the steering mechanism is also used to adjust the center orientation of the depth camera.
[0103] The temperature probe is calibrated using a steering mechanism to align its center with the center of the burner or cookware, including:
[0104] The steering mechanism is controlled to drive the depth camera to rotate and acquire depth images of the stove.
[0105] Based on the collected depth image of the stove, determine the center position of the burner or pot;
[0106] The temperature probe is driven to align with the center of the stove or cookware by a steering mechanism.
[0107] For details not covered in this embodiment, please refer to the above embodiments. Figure 9 As shown, the control method includes:
[0108] S310: Control the steering mechanism to drive the depth camera to rotate and acquire depth images of the stove.
[0109] Specifically, please refer to Figure 1 , Figure 2 and Figure 3 The temperature probe 31 integrates a depth camera 33 (the depth camera 33 can be located inside the temperature probe 31). The depth camera 33 moves synchronously with the temperature probe 31, and the steering mechanism 32 can adjust the center orientation of the depth camera 33. When the stove 10 is on, the depth camera 33 can be rotated by controlling the steering mechanism 32, and the depth camera 33 can acquire depth images of various locations on the two-dimensional plane where the stove 10 is located. It should be noted that the shape of the actual object in the image can be obtained from the depth image acquired by the depth camera 33. If a two-dimensional camera is used, the shape of the actual object in the image cannot be obtained.
[0110] S320. Determine the center position of the burner or cookware based on the collected depth image of the stove.
[0111] Optionally, based on the acquired depth image of the stove, the center position of the burner or cookware is determined, including:
[0112] S3201. Identify the burner or cookware in the depth image of the cooktop.
[0113] Specifically, please refer to Figure 1 , Figure 2 and Figure 3 The range hood 20 stores various cookware and burner shape models in its memory. Based on the depth image of the stove 10 captured by the depth camera 33, the depth image of the stove 10 is compared with the various cookware and burner shape models stored in the memory to identify whether there is a cookware at the stove 10. If it is identified that there is a cookware at the stove 10, the specific type of cookware can be further determined based on the various cookware shape models stored in the memory. If it is identified that there is only a burner at the stove 10 and no cookware is placed there, the specific shape of the burner can be further determined based on the various burner shape models stored in the memory.
[0114] S3202. Extract the outer contour of the burner or cookware from the depth image of the stove and fit it into a standard graphic.
[0115] Specifically, please refer to Figure 1 , Figure 2 and Figure 3 Extract the outer contour of the burner or cookware from the 10-depth image of the stove and fit it into a standard shape. For example, the standard shape can be a standard circle, ellipse, rectangle, square, and triangle, etc. Figure 10A This is a schematic diagram of a depth camera viewing a stove or cookware from the front, according to an embodiment of the present invention. Figure 10B This is a schematic diagram of a depth camera viewing a stove or cookware at an angle, as provided in an embodiment of the present invention. Figure 10A and Figure 10B As shown, if the depth camera 33 is located directly above the stove 10, the standard shape fitted to the extracted outer contour of the burner or pot will depend on the actual shape of the burner or pot. If the depth camera 33 is not located directly above the stove 10, the standard shape fitted to the extracted outer contour of the burner or pot may differ from the actual shape of the burner or pot due to the tilted viewing angle. For example, the standard shape fitted to the outer contour of a round pot will be elliptical.
[0116] S3203. Determine the geometric center of the standard graphic as the center position of the stove or cookware.
[0117] Specifically, please refer to Figure 1 , Figure 2 , Figure 10A and Figure 10B The geometric center of the standard graphic is determined, and the geometric center of the standard graphic is used as the center position of the stove or cookware. This can maximize the integration and elimination of the uncertainty deviation of the actual shape of various stoves or cookware for temperature detection, which is conducive to increasing the temperature detection accuracy of the temperature detection module 30.
[0118] S330: The temperature probe is driven to face the center of the stove or cookware via a steering mechanism.
[0119] Specifically, the center of the temperature probe 31 is driven by the steering mechanism 32 until the center of the temperature probe 31 is oriented to the center of the stove or cookware. When the center of the temperature probe 31 is at the center of the stove or cookware, more accurate temperature data can be collected in real time. By comparing this temperature data with the temperature data model stored in the memory, the current cooking type can be better determined, which is more in line with the user's cooking status.
[0120] S340: Real-time temperature monitoring of the center position of the burner or pot when the stove is on.
[0121] S350: Determine the current cooking type based on the temperature of the center position of the burner or pot when the stove is on in real time.
[0122] S360: Adjust the airflow of the range hood according to the current cooking type.
[0123] The technical solution in this embodiment of the invention details how to use a steering mechanism to calibrate the center orientation of the temperature probe to the center position of the burner or cookware. When the stove is on, the steering mechanism is controlled to drive the depth camera to rotate. The depth camera can collect depth images at various points on the two-dimensional plane where the stove is located. Based on the collected depth images of the stove, the outer contour of the burner or cookware is fitted into a standard shape. This can maximize the integration and elimination of uncertain deviations in temperature detection caused by the actual shape of various burners or cookware, which is beneficial to increasing the accuracy of temperature detection by the temperature detection module.
[0124] Figure 11 This is a flowchart illustrating another control method for a kitchen appliance provided by an embodiment of the present invention. This embodiment is an optimization based on the above embodiment. Optionally, a steering mechanism is used to calibrate the center orientation of the temperature probe to the center position of the stove or cookware, including:
[0125] Each time the stove is turned on, or at preset intervals after the stove is turned on, the center of the temperature probe is calibrated to the center of the burner or cookware using a steering mechanism.
[0126] For details not covered in this embodiment, please refer to the above embodiments. Figure 11 As shown, the control method includes:
[0127] S410. Each time the stove is turned on or at preset intervals after the stove is turned on, the center of the temperature probe is calibrated to the center of the burner or cookware using the steering mechanism.
[0128] Specifically, please refer to Figure 1 , Figure 2 and Figure 3 Each time the stove 10 is turned on, the center of the temperature probe 31 is aligned with the center of the burner or pot using the steering mechanism 32. This allows for more accurate real-time temperature data collection. By comparing this temperature data with the temperature data model stored in the memory, the current cooking type can be better determined, more closely matching the user's cooking status. Alternatively, to further improve the accuracy of temperature data detection and avoid positional deviations after a single calibration, the center of the temperature probe 31 can be aligned with the center of the burner or pot using the steering mechanism 32 at preset intervals after the stove 10 is turned on. The preset interval depends on the cooking process; for example, the preset interval could be 10 seconds.
[0129] S420: Real-time acquisition of the temperature at the center of the burner or pot when the stove is on.
[0130] S430: Determine the current cooking type based on the temperature of the center position of the burner or pot when the stove is on in real time.
[0131] S440. Adjust the airflow of the range hood according to the current cooking type.
[0132] The technical solution in this embodiment of the invention details how to use a steering mechanism to calibrate the center of the temperature probe to the center of the burner or cookware. Every time the stove is turned on or at preset intervals after the stove is turned on, the steering mechanism is used to calibrate the center of the temperature probe to the center of the burner or cookware. This can further improve the accuracy of temperature data detection and avoid positional deviations that may occur after the temperature probe is calibrated.
[0133] Figure 12 This is a flowchart illustrating another control method for a kitchen appliance provided in this embodiment of the invention. This embodiment is an optimization based on the above embodiment. Optionally, before calibrating the center orientation of the temperature probe to the center position of the stove or cookware using the steering mechanism, the method further includes:
[0134] Temperature is collected in real time after the stove is turned on;
[0135] When the temperature fluctuation within a preset time period is within a preset fluctuation range, the temperature value within the preset time period is compared with the temperature range corresponding to various preset cooking types.
[0136] The temperature value within the preset time period is determined to be outside the temperature range corresponding to any preset cooking type.
[0137] For details not covered in this embodiment, please refer to the above embodiments. Figure 12 As shown, the control method includes:
[0138] S510: The temperature is collected in real time after the stove is turned on.
[0139] Specifically, please refer to Figure 1 , Figure 2 and Figure 3 The range hood 20 stores temperature data models of various cooking states throughout the entire cooking process of the cooktop 10 in its memory. For example, the cooking states can be no-pot state, stir-fry state, soup-making state, and hot oil state, etc. The temperature data of these cooking states are relatively stable and can last for a period of time. The correspondence between these cooking states, temperature data, and duration is also stored in the memory, i.e., various preset cooking types. After the cooktop 10 is turned on, the temperature probe 31 can collect the temperature at the cooktop 10 in real time.
[0140] S520. When the temperature fluctuation within a preset time period is within a preset fluctuation range, compare the temperature value within the preset time period with the preset temperature range corresponding to various cooking types.
[0141] Specifically, please refer to Figure 1 , Figure 2 and Figure 3 During the real-time temperature monitoring of the stove 10 by the temperature probe 31, if the temperature fluctuation within a preset time period falls within a preset fluctuation range, the temperature value within the preset time period can be compared with the preset temperature ranges corresponding to various cooking types. For example, the preset time period can be 10 seconds, and the preset temperature fluctuation range collected by the temperature probe 31 can be 100±10 degrees Celsius. The temperature value within the preset time period is compared with the preset temperature ranges corresponding to various cooking types. For example, the temperature fluctuation range corresponding to the soup cooking state can be 100±10 degrees Celsius. If, within 10 seconds, the temperature fluctuation collected by the temperature probe 31 at the stove 10 meets the temperature fluctuation range corresponding to the soup cooking state, then the center of the temperature probe 31 is facing the pot, and the cooking state is soup cooking. It should be noted that, based on the real-time temperature collected by the temperature probe 31 at the stove 10, the temperature value within the preset time period can be compared with the preset temperature ranges corresponding to various cooking types in real-time or at regular intervals to determine the current cooking type of the stove 10. In addition, the correspondence between the cooking state, temperature data, and duration stored in the memory is exemplified as follows: when the oil is hot in the wok, the stove is on high heat for 5 seconds, and the temperature is 200±10 degrees Celsius; when the soup is simmering in the soup pot, the stove is on low heat for 30 seconds, and the temperature is 98±10 degrees Celsius.
[0142] S530, Determine that the temperature value within the preset time does not belong to the temperature range corresponding to any preset cooking type.
[0143] Specifically, please refer to Figure 1 , Figure 2 and Figure 3When the temperature fluctuation within a preset time is within a preset fluctuation range, the temperature value within the preset time is compared with the temperature range corresponding to various preset cooking types. If the temperature value within the preset time is compared with the correspondence between the cooking state, temperature data and duration stored in the memory, and the temperature value within the preset time does not belong to the temperature range corresponding to any preset cooking type, then the position of the center orientation of the temperature probe 31 is deviated, and the center orientation of the temperature probe 31 needs to be recalibrated. For example, if the temperature fluctuation collected by the temperature probe 31 in real time within a preset time of 10 seconds is 120±10 degrees, this temperature fluctuation is compared with the preset temperature ranges corresponding to various cooking types. The temperature ranges corresponding to various cooking types stored in the memory are, for example, 150±10 degrees for stir-frying, 100±10 degrees for soup boiling, and 180±20 degrees for hot oil. If none of these preset temperature ranges for various cooking types matches 120±10 degrees, then 120±10 degrees does not belong to any of the preset cooking type's temperature range, indicating a deviation in the center orientation of the temperature probe 31. It should be noted that during the calibration process of the temperature probe 31, the airflow of the range hood 20 is adjusted according to the temperature data. Once the center orientation of the temperature probe 31 is correct and without deviation, the steering mechanism 32 is used to adjust the center orientation of the temperature probe 31 to the center position of the burner or cookware.
[0144] S540, use the steering mechanism to calibrate the center of the temperature probe to the center of the stove or cookware.
[0145] S550: Real-time temperature monitoring of the center of the burner or cookware when the stove is on.
[0146] S560: Determine the current cooking type based on the temperature of the center position of the burner or pot when the stove is turned on, as collected in real time.
[0147] S570: Adjust the airflow of the range hood according to the current cooking type.
[0148] The technical solution in this embodiment of the invention details the process of using a steering mechanism to calibrate the center orientation of the temperature probe to the center position of the burner or cookware. It compares the temperature value within a preset time period with the preset temperature ranges corresponding to various cooking types, pre-determining the current cooking type or cooking state of the stove. Under the correct pre-stored cooking state, the center orientation of the temperature probe is then calibrated to the center position of the burner or cookware. This improves the accuracy of temperature detection by the temperature detection module, avoids situations where the range hood adjusts its airflow based on temperature data without meeting the cooking type requirements of the kitchen appliance, enhances the intelligence of the kitchen appliance, and improves the user's cooking experience.
[0149] Figure 13 This is a schematic diagram of a control device for a kitchen appliance according to an embodiment of the present invention. This control device is applicable to the cooking process of a user using a stove and a range hood.

This control method utilizes the intelligent adjustability of the temperature probe's center orientation, automatically calibrating and adjusting the center orientation of the temperature probe to the center position of the burner or cookware based on the user environment and installation dimensions. This avoids the problem of temperature detection data deviation caused by installation positional deviations, which is beneficial to improving the temperature detection accuracy of the temperature detection module. The range hood's operating process adjustment based on the temperature detection response is more consistent with the actual cooking state, improving the intelligence of the kitchen appliance and enhancing the user's cooking experience.

The temperature extreme point determination subunit is used to determine the temperature extreme points in the first and second directions.
