Description

Technical Field

[0001] This application relates to the field of intelligent cooktop technology, specifically to an anti-dry-burning system, control method, and cooktop equipment for a cooktop. Background Technology

[0002] Existing anti-dry-burning systems for cooktops employ both contact and non-contact temperature detection methods. Contact temperature detection primarily utilizes fixed thermocouple probes mounted on the cooktop. However, due to the fixed probe position and height, it cannot accommodate cookware of varying sizes and shapes, easily leading to measurement errors and even misjudging dry-burning conditions. Non-contact temperature detection, such as deploying infrared temperature probes above the range hood, can detect abnormal temperature rises inside the pot and notify the cooktop to shut off. However, its accuracy is easily affected by external factors such as pot lid obstruction, steam, fumes, or ambient temperature fluctuations, making it difficult to accurately distinguish between the pot's surface temperature and the actual temperature inside, thus also suffering from measurement interference.

[0003] Due to inaccurate temperature detection, misjudgment issues are also quite prominent in existing technologies. Traditional threshold judgment logic is relatively simple and cannot dynamically distinguish between normal cooking operations and dry burning situations where an empty pot is continuously heated. It is easy for users' operating habits, such as temporarily moving the pot, adding oil or water, to trigger accidental shut-off, affecting the user experience of the stove and increasing safety hazards during the cooking process. Summary of the Invention

The distance sensor is used to acquire distance data between the temperature probe and the bottom of the pot; The controller is electrically connected to the distance sensor and the lifting drive mechanism, and is used to control the lifting drive mechanism to drive the temperature probe to rise and fall according to the distance data, and to identify the cooking mode according to the temperature data obtained by the temperature probe, and to control the stove to turn off according to the anti-dry burning strategy corresponding to the cooking mode.

[0006] Furthermore, the temperature probe is provided with an elastic contact head, which is configured to be tilted under force to fit the bottom of cookware of different shapes.

[0007] Furthermore, the temperature probe is also equipped with a resistance detection mechanism, which is used to detect the lifting resistance encountered in real time during the lifting process.

[0008] Furthermore, the lifting drive mechanism is a linear motor or a drive cylinder.

[0009] Furthermore, the controller includes a probe control module, which is used for: When the distance data is less than or equal to a first preset distance threshold and the duration is greater than or equal to a first preset duration, the temperature probe is controlled to rise and contact the bottom of the pot; After the temperature probe rises, if the detected distance data is greater than a second preset distance threshold, the system will control the user to place the cookware and reduce the stove's heat. If the distance data remains greater than the second preset distance threshold for a period of time greater than or equal to a second preset duration, the system will control the temperature probe to descend. If the frequency of the distance data changes exceeds a preset frequency threshold, the temperature probe is controlled to descend to avoid colliding with the moving cookware.

[0010] Furthermore, the controller also includes an anti-dry-burning module, which is used to predict the temperature inside the pot based on the temperature data obtained by the temperature probe through a difference equation and identify the cooking mode; when the cooking mode is a water-cooking mode, it calculates the weight of water and food inside the pot through a preset weight prediction formula to obtain the anti-dry-burning time threshold; and controls the stove to turn off according to the preset first temperature threshold and the anti-dry-burning time threshold.

[0011] Furthermore, the anti-dry-burning module is also used to control the stove to turn off when the cooking mode is a waterless cooking mode, according to a preset second temperature threshold; the second temperature threshold is greater than the first temperature threshold.

[0012] Furthermore, the controller includes: an early warning module, used to control the sound prompting device to emit a prompting sound when the distance data is detected to be greater than a second preset distance threshold.

[0013] This application also provides a method for controlling dry burning in a cooktop, applied to the dry burning prevention system, the method comprising: Obtain the distance data between the temperature probe and the bottom of the pot; When the distance data is less than or equal to a first preset distance threshold, the temperature probe is controlled to rise and contact the bottom of the pot; Based on the temperature data obtained by the temperature probe in contact with the bottom of the pot, the temperature inside the pot is predicted by the difference equation, and the cooking mode is identified. When the cooking mode is a water-cooking mode, the weight of water and food in the pot is calculated using a preset weight prediction formula, thereby obtaining the anti-dry-burning time threshold. The stove is turned off based on the preset first temperature threshold and the anti-dry burning time threshold. When the cooking mode is the waterless cooking mode, the stove is turned off according to the preset second temperature threshold.

[0023] Figure 1 This is a structural block diagram of the anti-dry-burning system according to an embodiment of this application; Figure 2 This is an overall flowchart of the anti-dry-burning control method according to an embodiment of this application; Figure 3 These are partial step diagrams of the anti-dry-burning control method according to embodiments of this application; Figure 4 This is a hardware structure block diagram of the server for the anti-dry-burning control method of this application embodiment.

[0024] This application provides an anti-dry-burning system for a cooktop, which is installed on a gas stove or other types of cooking stove. For example... Figure 1 As shown, the anti-dry-burning system includes a temperature probe 1, a distance sensor 2, a lifting drive mechanism 3, and a controller 4.

[0025] Temperature probe 1 is connected to lifting drive mechanism 3 and moves up and down relative to stove burner under the drive of lifting drive mechanism 3.

[0026] The distance sensor 2 is used to acquire the distance data between the temperature probe 1 and the bottom of the pot.

[0027] The controller 4 is electrically connected to the distance sensor 2 and the lifting drive mechanism 3. It is used to control the lifting drive mechanism 3 to drive the temperature probe 1 to rise and fall according to the distance data, and to identify the cooking mode according to the temperature data obtained by the temperature probe 1, and to control the stove to turn off according to the anti-dry burning strategy corresponding to the cooking mode.

[0028] Specifically, the temperature probe 1 is connected to the lifting drive mechanism 3 and can move up and down under the drive of the lifting drive mechanism 3 to maintain contact with the bottom of the pot. The distance sensor 2 can be installed near the temperature probe 1 to monitor the distance between the temperature probe 1 and the bottom of the pot in real time. The controller 4 receives the distance data detected by the distance sensor 2 and controls the operation of the lifting drive mechanism 3 based on the distance data, as well as processes the temperature data of the temperature probe 1.

[0029] This application's stove anti-dry-burning system integrates a temperature probe 1, a distance sensor 2, a lifting drive mechanism 3, and a controller 4, enabling it to adapt to cookware of different sizes, shapes, and curvatures. The lifting drive mechanism 3 automatically raises and lowers the temperature probe 1, ensuring precise contact with the bottom of the pot and improving temperature measurement accuracy. The distance sensor 2 monitors the distance between the temperature probe 1 and the cookware in real time, and the controller 4 intelligently adjusts the position of the temperature probe 1 based on this information, improving temperature measurement accuracy and effectively preventing dry burning and misjudgments. Furthermore, the system can identify different cooking modes and automatically control the heat and activate the anti-dry-burning shut-off function according to the corresponding anti-dry-burning strategy, enhancing safety, reducing energy waste, and providing users with a more convenient and comfortable cooking experience.

[0030] In some possible implementations, the lifting drive mechanism 3 can be a linear motor or a drive cylinder, and the temperature probe 1 can be connected to the output end of the lifting drive mechanism 3 through a transmission structure such as a linkage structure, cam transmission structure, gear transmission structure, or threaded transmission structure. The temperature probe 1 is set in the through hole in the middle of the stove burner cap, and under the drive of the lifting drive mechanism 3, it can rise along the through hole in the middle of the burner cap to contact the bottom of the pot, or descend into the stove.

[0031] In some other possible implementations, the output of the lifting drive mechanism 3 can be directly connected to the temperature probe 1 to drive the temperature probe 1 to rise and fall.

[0032] In some possible implementations, the temperature probe 1 can be a thermocouple probe, a thermistor probe, a resistance temperature detector, an infrared temperature probe, or a pressure temperature probe that can contact the bottom of the cookware to measure temperature.

[0033] Furthermore, the temperature probe 1 is equipped with an elastic contact head, which is configured to be tilted under force to fit the bottom of cookware of different shapes.

[0034] The flexible contact head can be made of a high-temperature resistant spring structure, which adaptively tilts when in contact with the bottom of the pot to accommodate pot bottoms of different shapes and curvatures. The flexible contact head is tightly integrated with the sensor part of the temperature probe 1 to ensure accurate temperature measurement when in contact with the bottom of the pot.

[0035] In another possible implementation, the elastic contact head can also be designed as one or more cantilever structures, with its free end connected to the sensor of the temperature probe 1. When the probe contacts the bottom of the pot, the cantilever structure can tilt accordingly according to the shape of the bottom of the pot to maintain close contact with the bottom of the pot.

[0036] This embodiment of the application improves the adaptability of the temperature probe 1 to the bottom of pots with different shapes by setting an elastic contact head on the temperature probe 1, reduces temperature measurement error, and improves the accuracy of subsequent anti-dry burning and shut-off conditions and the safety of the cooking process.

[0037] Furthermore, the temperature probe 1 is also equipped with a resistance detection mechanism 5, which is used to detect the lifting resistance encountered in real time during the lifting process.

[0038] In this embodiment, the resistance detection mechanism 5 can be installed in the drive path of the lifting drive mechanism 3. For example, a pressure sensor can be installed in the transmission structure below the temperature probe 1 to monitor in real time the resistance encountered by the temperature probe 1 during lifting, such as resistance caused by the pot shifting. When the resistance detected by the resistance detection mechanism 5 exceeds a preset safety threshold, the controller 4 will immediately receive a signal and control the current operation of the lifting drive mechanism 3 to stop, and drive the temperature probe 1 back to a safe position to avoid damage to the pot or the temperature probe 1.

[0039] Furthermore, the controller 4 includes a probe control module 41, which is used to: control the temperature probe 1 to rise and contact the bottom of the pot when the distance data is less than or equal to a first preset distance threshold and the duration is greater than or equal to a first preset duration; after the temperature probe 1 rises, if the detected distance data is greater than a second preset distance threshold, control the user to put the pot down and reduce the stove heat; if the distance data continues to be greater than the second preset distance threshold for a period of time greater than or equal to a second preset duration, control the temperature probe 1 to fall; if the frequency of the distance data changes exceeds a preset frequency threshold, control the temperature probe 1 to fall to avoid collision with the moving pot.

[0040] Specifically, the probe control module 41 is electrically connected to the ranging sensor 2, the lifting drive mechanism 3, the early warning module 43, the firepower adjustment module, and the timing module, respectively.

[0041] The first preset distance threshold is less than the second preset distance threshold. When the distance data is less than or equal to the first preset distance threshold and the duration is greater than or equal to the first preset duration, it meets the characteristics of the pot being placed on the stove. At this time, the probe control module 41 controls the lifting drive mechanism 3 to raise the temperature probe 1 so that the temperature probe 1 contacts the bottom of the pot.

[0042] The first preset distance threshold is set to take into account different shapes of cookware and bottom curvature, as well as the contact gap between the temperature probe 1 and the cookware, ensuring the accuracy of temperature measurement. The first preset duration refers to the shortest time that this state needs to last when the distance between the temperature probe and the bottom of the cookware is less than or equal to the first preset distance threshold, to ensure that it can be confirmed that the cookware has been stably placed on the stove, avoiding misjudgments caused by the cookware being placed briefly or unstablely.

[0043] After the temperature probe 1 rises, if the distance between the risen temperature probe 1 and the bottom of the pot is detected to be greater than the second preset distance threshold, it indicates that the pot has left the stove. At this time, the probe control module 41 can remind the user to put the pot back down by controlling the warning module and control the firepower adjustment module to reduce the firepower of the stove. If the timing module detects that the distance data is greater than the second preset distance threshold for a period of time that is greater than or equal to the second preset duration, the probe control module 41 controls the lifting drive mechanism 3 to lower the temperature probe 1.

[0044] The second preset duration refers to the longest period during which the distance between the temperature probe 1 and the bottom of the pot is allowed to exceed a second preset distance threshold after the temperature probe 1 rises. This duration setting is used to identify whether the user has not placed the pot on the stove for an extended period. The second preset duration can be set based on expectations of user behavior and cooking habits.

[0045] If the distance data detected by the distance sensor 2 between the temperature probe 1 and the bottom of the pot changes rapidly, exceeding the normal range, it can identify the act of tossing the pot or other abnormal movement. The preset frequency threshold refers to the upper limit of the number of times the distance data between the temperature probe 1 and the bottom of the pot rises or falls within a certain period of time. When this number exceeds the set threshold, it can usually be determined that a tossing operation is in progress. At this time, the probe control module 41 controls the temperature probe 1 to descend to avoid the moving pot.

[0046] The probe control module 41 is also used to control the lifting drive mechanism 3 to drive the temperature probe 1 to descend after the stove is completely turned off.

[0047] In this embodiment of the application, when it is mentioned that the temperature probe 1 performs a descent operation, it means that the temperature probe 1 moves to its preset initial position inside the stove, which is the resting position of the temperature probe 1 when it is not performing a temperature monitoring task.

[0048] The anti-dry-burning system in this application precisely adjusts the position of the temperature probe 1 using a first preset distance threshold and a second preset distance threshold. This ensures close contact between the probe and the bottom of cookware of different shapes, adapting to various cooking needs and reducing temperature measurement errors. Intelligent control of the temperature probe 1's position and adaptive tracking of the cookware bottom provides users with a safe, efficient, and easy-to-operate cooking environment, while reducing the risk of misjudgment and dry-burning, and extending the lifespan of the cookware.

[0049] Furthermore, the controller 4 also includes an anti-dry-burning module 42, which is electrically connected to the temperature probe 1, the firepower adjustment module, and the timing module, respectively.

[0050] The anti-dry-burning module 42 is used to predict the temperature inside the pot based on the temperature data obtained by the temperature probe 1 and identify the cooking mode through a differential equation. When the cooking mode is a water-cooking mode, the weight of water and food in the pot is calculated by a preset weight prediction formula to obtain the anti-dry-burning time threshold. The stove is turned off according to the preset first temperature threshold and the anti-dry-burning time threshold.

[0051] Furthermore, the anti-dry-burning module 42 is also used to control the stove to turn off when the cooking mode is the waterless cooking mode, according to a preset second temperature threshold; the second temperature threshold is greater than the first temperature threshold.

[0052] The anti-dry-burning module 42 in the controller 4 of this embodiment includes: The temperature prediction and cooking mode recognition unit is used to receive temperature data from the temperature probe 1, predict the temperature inside the pot using a difference equation, and perform cooking mode recognition.

[0053] Formula for predicting the temperature inside the pot:

[0054] : The predicted actual temperature inside the pot at time step k+1.

[0055] The temperature measurement value at time step k is usually the temperature data obtained by temperature probe 1.

[0056] Time step: The time interval between two measurements.

[0057] Time constant: Represents the system's response speed to temperature changes, and is related to the system's heat capacity and heat transfer characteristics.

[0058] : The actual temperature inside the pot at time step k.

[0059] Based on the predicted actual temperature change curve inside the pot and known cooking mode characteristics, the current cooking mode is identified as either water-cooked or waterless cooking mode.

[0060] Water-cooking mode control unit 421: After recognizing the water-cooking mode, it uses a preset weight prediction formula to calculate the total weight of water and food in the pot. Based on the predicted total weight M, it estimates the time required for the water to boil dry, thereby determining the anti-dry-burning time threshold, which can be obtained by looking up a pre-built dry-burning time reference table; and controls the stove to turn off the flame based on the preset first temperature threshold and the anti-dry-burning time threshold.

[0061] Weight prediction formula:

[0062] in, The thermal efficiency of the stove. This refers to the power output corresponding to each heat setting on the stove. Burning time The average specific heat capacity of water and food ingredients, This is the initial firing temperature.

[0063] The first temperature threshold is a preset upper temperature limit set in the water-cooking mode to prevent dry burning. When the water in the pot approaches or reaches this temperature, it means that the water is about to evaporate or has already completely evaporated. Continuing to heat it may cause the food to burn or damage the cookware. Therefore, this threshold is used to trigger the anti-dry burning system's protection mechanism, automatically adjusting or shutting off the cookware.

[0064] Specifically, controller 4 receives temperature data from temperature probe 1 in real time and compares the real-time temperature data with a first temperature threshold. Simultaneously, it starts timing from the moment of ignition and compares the elapsed time with an anti-dry-burning time threshold. If the real-time temperature is greater than or equal to the first temperature threshold, or if the elapsed time is greater than or equal to the anti-dry-burning time threshold, controller 4 will trigger a shut-off command. Controller 4 sends a shut-off command to the flame control module, causing the stove to stop heating.

[0065] Waterless cooking mode control unit 422: Used to control the stove to shut off after recognizing a waterless cooking mode, using a preset second temperature threshold. The second temperature threshold is a safe upper limit temperature set for the waterless cooking mode. Waterless cooking mode is typically used for cooking methods such as frying, stir-frying, and grilling, which usually require higher temperatures to achieve the desired cooking effect. Because there is no water or other liquid in the pan to regulate temperature and absorb heat, the temperature rises faster, thus requiring a higher temperature threshold to prevent premature shut-off.

[0066] Specifically, the controller 4 receives temperature data from the temperature probe 1 in real time and compares the real-time temperature data with a second temperature threshold. When the monitored real-time temperature data is greater than or equal to the second temperature threshold, the controller 4 sends a fire-off command to the fire control module, causing the stove to stop heating.

[0067] The anti-dry-burning module 42 in this embodiment uses pot temperature prediction and cooking mode recognition technology to employ different anti-dry-burning strategies for different cooking modes, improving cooking flexibility and efficiency, enhancing cooking safety, reducing energy waste, and extending the lifespan of the stove. By precisely controlling the heat and predicting the pot temperature, it effectively prevents dry burning and food burning, thus improving cooking safety.

[0068] Furthermore, the controller 4 includes an early warning module 43, which is electrically connected to the ranging sensor 2 and is used to control the sound prompting device to emit a prompting sound when the detected distance data is greater than a second preset distance threshold.

[0069] Specifically, the warning module 43 receives distance data from the ranging sensor 2 in real time. When the distance data exceeds a second preset distance threshold, the warning module 43 triggers a warning signal. The warning module 43 controls the sound prompt device to emit a warning sound, reminding the user that there may be a situation where no pot is placed or the pot has been moved. By promptly reminding the user of situations where no pot is placed or the pot has been moved, the warning module 43 helps prevent gas leaks and fire risks, improving kitchen safety. It also prevents the stove from burning dry without pots, thus avoiding unnecessary energy waste.

[0070] This application also provides a method for controlling dry burning in a stove, applied to the anti-dry burning system, such as... Figure 2 and 3 As shown, the anti-dry-burning control method includes: After the stove is turned on; S100, acquire the distance data between the temperature probe and the bottom of the pot.

[0071] S200, when the distance data is less than or equal to a first preset distance threshold, control the temperature probe to rise until it contacts the bottom of the pot.

[0072] S300: Based on the temperature data obtained by the temperature probe in contact with the bottom of the pot, the temperature inside the pot is predicted by the differential equation, and the cooking mode is identified.

[0073] S400, when the cooking mode is a water-cooking mode, the weight of water and food in the pot is calculated by a preset weight prediction formula to obtain the anti-dry-burning time threshold.

[0074] S500 controls the stove to turn off based on a preset first temperature threshold and an anti-dry-burning time threshold.

[0075] S600, when the cooking mode is the waterless cooking mode, the stove is turned off according to the preset second temperature threshold.

[0076] After the stove is turned on, the system automatically acquires the distance data between the temperature probe and the bottom of the pot. When the distance is less than or equal to a preset threshold, the system controls the probe to rise and contact the bottom of the pot, ensuring the accuracy of temperature measurement. Based on the temperature data acquired during contact with the bottom of the pot, the system predicts the temperature inside the pot using a differential equation, intelligently identifies the current cooking mode, and provides different anti-dry-burning strategies for different cooking modes. Automated anti-dry-burning control reduces the user's monitoring burden during cooking, lowers the risk of cooking failure or equipment damage due to improper operation, and improves the convenience and comfort of cooking. The system can automatically adjust the control strategy according to different cooking environments, improving environmental adaptability and ensuring reliable anti-dry-burning protection under various cooking conditions.

[0077] This application embodiment also provides a stove device, including a processor and a memory, wherein the memory stores at least one instruction, at least one program, code set or instruction set, and the at least one instruction, the at least one program, the code set or instruction set is loaded and executed by the processor to implement the anti-dry burning control method.
