Description

A gas stove anti-dry-burning control system and its control method Technical Field

[0001] This invention relates to the field of kitchen appliance technology, and in particular to an anti-dry-burning control system and control method for a gas stove. Background Technology

[0002] Gas stoves use liquefied petroleum gas, manufactured gas, natural gas, or other gases as fuel to heat cookware placed on the burner of the gas stove in order to cook the food inside the cookware.

[0003] During the use of gas stoves, the continuous cooking process can cause moisture loss from the pot, leading to dry burning. Excessive dry burning can damage the gas stove and the pot, and even create safety hazards. Current technology incorporates dry burning detection sensors in gas stoves. These sensors monitor the temperature of the pot to determine if dry burning has occurred, and promptly shut off the gas stove when dry burning is detected, thus ensuring personal and property safety.

[0004] However, during the process of the burner heating the cookware, the cookware will be in a high-temperature state continuously. Since the dry-burn detection sensor has built-in electronic components, these electronic components will be in a high-temperature environment for a long time, which will affect the service life of the electronic components, that is, the service life of the dry-burn detection sensor. This will increase the cost of the gas stove itself and fail to meet the requirements of economic energy saving. Summary of the Invention

[0005] This invention provides a gas stove anti-dry-burning control system and control method to improve the service life of the dry-burning detection module, reduce the cost of the gas stove, and meet the needs of economic and energy-saving.

The gas stove includes at least one burner, and the gas stove anti-dry burning control system includes a cooking detection module and at least one dry burning detection module corresponding to the burner. The dry burning detection module is movably disposed at the center of the burner. The gas stove anti-dry burning control method includes:

[0007] When the burner is started to heat the cookware, the cooking identifier of the cookware heated by the burner is obtained based on the cooking detection module;

[0009] Optionally, the detection position of the dry-boil detection module can be controlled according to the cooking markings on the cookware, including:

[0010] Determine whether the cooking method of the cookware is the preset method based on the cooking markings on the cookware.

[0011] If not, the dry-burn detection module is controlled to be in a non-working position; wherein, when the dry-burn detection module is in a non-working position, the cookware is outside the dry-burn detection range of the dry-burn detection module.

[0012] Optionally, the detection position of the dry-boil detection module can be controlled according to the cooking markings on the cookware, and the following additional features may be included:

[0013] If the cooking method of the cookware is determined to be the preset mode based on the cooking markings on the cookware, then the dry-burn detection module is controlled to be in the working position; wherein, when the dry-burn detection module is in the working position, the cookware is within the detection range of the dry-burn detection module.

[0014] Optionally, the anti-dry-burning control method for gas stoves also includes:

[0015] When the cooking method of the cookware is preset and the dry burning detection module is in the working position, the temperature information of the cookware heated at the burner corresponding to the dry burning detection module is obtained in real time based on the dry burning detection module.

[0016] The operating status of the burner for the cookware is controlled based on the temperature information of the cookware.

[0017] Optionally, based on the temperature information of the cookware, the operating state of the burner of the cookware can be controlled, including:

[0018] Based on the temperature information of the cookware at each time point, determine the rate of temperature rise of the cookware at the current time.

[0019] Determine whether the current rate of temperature rise is greater than or equal to the preset rate;

[0020] If so, turn off the burner containing the cookware.

[0021] Optionally, based on the temperature information of the cookware, the operating state of the burner of the cookware can be controlled, including:

[0022] Based on the current temperature information of the cookware, determine whether the current temperature of the cookware is greater than the preset temperature;

[0023] If so, turn off the burner containing the cookware.

[0024] Optionally, the anti-dry-burning control method for gas stoves also includes:

[0025] After the burner is turned off, the dry burning detection module is placed in a non-working position; when the dry burning detection module is in a non-working position, the cookware is outside the dry burning detection range of the module.

[0026] Optionally, the anti-dry-burning control method for gas stoves also includes:

[0027] When the burner is started and ignited, the dry burning detection module corresponding to the burner is controlled to be in the working position; when the dry burning detection module is in the working position, the cookware is within the detection range of the dry burning detection module.

[0028] Secondly, the present invention also provides a gas stove anti-dry-burning control system, the gas stove including at least one burner; the gas stove anti-dry-burning control system includes: at least one dry-burning detection module, a cooking detection module and an anti-dry-burning control module corresponding to at least one burner;

[0029] The dry-burning detection module is located at the center of the burner.

[0030] The anti-dry-burning control module is connected to both the dry-burning detection module and the cooking detection module.

[0031] The anti-dry-burning control module is used to execute the anti-dry-burning control method of the gas stove mentioned above.

[0032] Optionally, the anti-dry-burning control system of the gas stove may also include: a drive mechanism;

[0033] The drive mechanism is connected to the dry burning detection module. The drive mechanism is used to drive the dry burning detection module to move, so as to control the detection position of the dry burning detection module.

[0034] The technical solution of this invention, by acquiring the cooking indicator of the cookware heated by the burner based on the cooking detection module when the burner is activated, and controlling the detection position of the dry-burn detection module according to the cooking indicator, allows for on-demand adjustment of the dry-burn detection module's position. When the dry-burn detection module needs to operate, it can detect dry burning of the cookware, improving the safety and stability of the gas stove. When the dry-burn detection module does not need to operate, it avoids the burner heating the cookware, preventing it from being continuously kept at a high temperature, thus avoiding prolonged high-temperature environments for the electronic components built into the dry-burn detection module. This extends the lifespan of the dry-burn detection module, reduces the cost of the gas stove, and meets the needs of economic and energy-saving practices. Attached Figure Description

[0053] It should be noted that the implementation methods provided in the embodiments of the present invention can be combined with each other without contradiction.

[0054] Example 1

[0055] This embodiment provides a gas stove anti-dry burning control system, which can improve the service life of the dry burning detection module, reduce the cost of the gas stove, and meet the needs of economic and energy saving. As shown in Figure 1, the gas stove 10 includes at least one burner 11, that is, the gas stove 10 may include one or more burners 11. This embodiment of the invention does not make specific limitations on this.

[0056] Referring again to Figure 1, the gas stove may further include a switch assembly 12, which allows the user to control the ignition of each burner 11. The switch assembly 12 may include rotary switches corresponding to each burner 11, allowing the user to adjust the flame intensity of each burner 11. Furthermore, each burner 11 may be equipped with a detachable pot holder 13, which supports pots placed on the burner 11, ensuring airflow at the burner 11 even after the pot is placed there, thus guaranteeing complete combustion of the gaseous fuel released at the burner 11. It should be noted that Figure 1 only exemplarily illustrates the structure of the gas stove; the specific structure of the gas stove in this embodiment can be designed according to actual needs, and this embodiment does not impose specific limitations on it.

[0057] Referring to Figures 1 and 2, the anti-dry-burning control system 20 of the gas stove includes at least one dry-burning detection module 22, a cooking detection module 23, and an anti-dry-burning control module 24, each corresponding to at least one burner 11. The dry-burning detection module 22 is movably disposed at the center of the burner 11. The anti-dry-burning control module 24 is connected to both the dry-burning detection module 22 and the cooking detection module 23. The anti-dry-burning control module 24 can control the opening and closing of both the dry-burning detection module 22 and the cooking detection module 23. When the burner 11 is started to heat the cookware, the anti-dry-burning control module 24 controls the cooking detection module 23 to open. When the cooking detection module 23 is open, the anti-dry-burning control module 24 receives the cooking indicator of the cookware from the cooking detection module 23 and determines the cooking mode of the cookware placed on the burner 11 based on the cooking indicator. It then controls the detection position of the dry-burning detection module 22 according to the cooking mode of the cookware. When the dry-burn detection module 22 is activated, its detection position is controlled so that the cookware is within its detection range. This allows the module to detect whether the cookware is dry-burning and react promptly if dry-burning occurs, improving the safety and stability of the gas stove and enhancing the user experience. When the dry-burn detection module 22 is not activated during the current cooking method, its detection position is controlled so that the cookware is outside its detection range. In this case, the module will not detect dry-burning, preventing the burner 11 from heating the cookware and keeping it at a high temperature. This avoids prolonged exposure of the electronic components within the dry-burn detection module 22 to high temperatures, which would affect their lifespan. This extends the lifespan of the dry-burn detection module 22, reduces the cost of the gas stove, and meets the needs of economic and energy-saving practices.

[0058] For example, as shown in Figure 3, when it is determined that the dry-burn detection module 22 needs to be activated in the current cooking mode, the dry-burn detection module 22 can be controlled to extend out of the burner 11 until it rises to a preset working height and then stops. This allows the dry-burn detection module 22 to detect whether the cookware is dry-burning and to react promptly when dry-burning occurs. Alternatively, as shown in Figure 4, when it is determined that the dry-burn detection module 22 does not need to be activated in the current cooking mode, the dry-burn detection module 22 can be controlled to retract into the burner 11 until it descends to a preset non-working height and then stops. This allows the dry-burn detection module 22 to avoid the high-temperature zone when not in use, improving its service life, reducing the cost of the gas stove, and meeting the needs of economic energy saving. It should be noted that the dry-burn detection module 22 can move up and down along the axial direction of the burner 11 at the center of the burner 11. This embodiment of the invention does not specifically limit the movement mode of the dry-burn detection module 22.

[0059] It is understandable that cooking methods can include, but are not limited to, steaming, boiling, and stir-frying. When the cooking mode is stir-frying, the ingredients need to be constantly stirred during the cooking process, and the user will not leave for a long time. In this case, there is no need to turn on the anti-dry-burning function. Moreover, if the anti-dry-burning function is turned on during this process, it may be accidentally triggered because the oil temperature rises too quickly when the oil is added. When the cooking method is steaming or boiling, the user does not need to stir frequently during the cooking process, so there may be situations where the user leaves. In this case, the anti-dry-burning function can be activated to prevent dry burning during the user's absence.

[0060] In an optional embodiment, when the burner 11 is started to heat the cookware, the anti-dry-burning control module 24 can control the cooking detection module 23 to turn on, so that the cooking detection module 23 can acquire the cooking mark of the cookware placed at the burner 11 and send the cooking mark to the anti-dry-burning control module 24; when the anti-dry-burning control module 24 determines that the current cooking mode of the cookware placed at the burner 11 is a preset mode based on the cooking mark it has received, such as steaming or boiling, it can control the dry-burning detection module 22 to rise to the working height and turn on the dry-burning detection module 22, so that the dry-burning detection module 22 can detect whether the cookware is dry-burning in real time and feed back the dry-burning detection result to The anti-dry-burning control module 24 can promptly shut off the corresponding burner 11 when it determines that the cookware is dry-burning based on the dry-burning detection results, thereby preventing safety hazards caused by dry-burning. Conversely, when the anti-dry-burning control module 24 determines, based on the received cooking indicators, that the current cooking mode of the cookware placed at the burner 11 is not the preset mode, such as the current cooking mode being stir-fry, it can control the dry-burning detection module 22 to be in a closed state and control the dry-burning detection module 22 to be lowered to a non-working height, so that the anti-dry-burning detection module 22 avoids the high-temperature area, improves the service life of the dry-burning detection module 22, reduces the cost of the gas stove, and meets the needs of economic energy saving.

[0061] Optionally, referring to Figure 1, the dry-burn detection module 22 may include a dry-burn detection probe 221. This probe 221 may contain a temperature sensor that monitors the temperature at the bottom of the pot on the burner 11 in real time to determine if the pot is dry-burning. The dry-burn detection probe 221 can be movably mounted at the center of the burner 11. When the dry-burn detection module 22 needs to be activated, the probe 221 rises and protrudes from the burner cap, allowing it to contact the bottom of the pot placed on the burner. When the dry-burn detection module 22 does not need to be activated, the probe 221 descends into the copper core of the burner 11, avoiding high-temperature areas.

[0062] Optionally, referring to Figures 1 and 5, a guide seat 41 is provided at the center of the burner 11, and the dry burning detection module 22 is fitted inside the guide seat 41.

[0063] Specifically, when controlling the detection position of the dry-burn detection module 22 according to the cooking markings on the cookware, the position of the dry-burn detection module 22 needs to be moved according to the cooking method. During this movement, the dry-burn detection module 22 may shift. To address this, a guide seat 41 is provided at the center of the burner 11, and the dry-burn detection module 22 is fitted inside the guide seat 41. When the dry-burn detection probe 221 of the dry-burn detection module 22 passes through the guide seat 41, the limiting effect of the guide seat 41 ensures that the dry-burn detection module 22 can move in a preset direction, preventing it from shifting during movement and ensuring the stability and accuracy of the dry-burn detection module 22 during displacement. For example, when the dry burning detection probe 221 moves up and down along the axial direction of the burner, the guide seat 41 can limit the movement trajectory of the dry burning detection probe 221 in the horizontal direction to ensure the concentricity of the dry burning detection probe 221 and the burner 11, and avoid the temperature recognition error caused by the eccentricity of the dry burning detection probe 221. Similarly, when the dry burning detection probe 221 moves forward, backward, left, and right, the guide seat 41 restricts the movement direction of the dry burning detection probe 221 to ensure that the movement direction of the dry burning detection probe 221 does not deviate.

[0064] In an optional embodiment, continuing to refer to Figures 1 and 5, the burner 11 of the gas stove 10 may include a nozzle seat 42, and the guide seat 41 may be specifically disposed in the central area of ​​the nozzle seat 42 to ensure the concentricity of the dry burning detection probe 221 and the nozzle seat 42, so that the dry burning detection probe 221 can detect the central area above the nozzle seat 42.

[0065] Optionally, referring to Figure 2, the gas stove's anti-dry-burning control system also includes a drive mechanism 25, which is connected to the dry-burning detection module 22. The drive mechanism 25 is used to drive the dry-burning detection module 22 to move, thereby controlling the detection position of the dry-burning detection module 22.

[0066] Specifically, the control end of the drive mechanism 25 can be connected to the drive signal output end of the anti-dry-burn control module 24, and the drive output end of the drive mechanism 25 can be mechanically connected to the dry-burn detection module 22. When the detection position of the dry-burn detection module 22 needs to be changed according to the cooking method, the anti-dry-burn control module 24 outputs a drive control signal to the drive mechanism 25. The drive mechanism 25 moves the dry-burn detection module 22 according to the corresponding action of the drive control signal, thereby flexibly controlling the detection position of the dry-burn detection module 22.

[0067] Optionally, referring to Figures 1, 5 and 6, the drive mechanism 25 includes a motor assembly 43 and a connecting rod 44; the output shaft 431 of the motor assembly 43 is mechanically connected to the first end of the connecting rod 44, and the second end of the connecting rod 44 is mechanically connected to the dry burning detection module 22.

[0068] Specifically, the dry burning detection module 22 may include a dry burning detection probe 221. The second end of the connecting rod 44 is fixedly connected to the bracket at the lower end of the dry burning detection probe 221 by fasteners or welding. In an exemplary embodiment, the drive mechanism 25 may also include a cover plate 45. The second end of the connecting rod 44 is provided with a cover plate base. Both the cover plate 45 and the cover plate base are provided with grooves. The cover plate 45 can be fixed to the cover plate base by fasteners. After the cover plate 45 and the cover plate base are fixed, the grooves on the cover plate 45 and the cover plate base form a receiving space, so that the bracket at the lower end of the dry burning detection probe 221 can be inserted into the receiving space, thereby realizing the fixed connection between the dry burning detection probe 221 and the connecting rod.

[0069] The motor assembly 43 may include an output shaft 431 and a motor 432. The first end of the connecting rod 44 is mechanically connected to one end of the output shaft 431 via a threaded connection. When the motor 432 rotates, it can drive the output shaft 431 to extend upward or retract downward, causing the output shaft 431 to drive the dry-burn detection probe 221 to extend upward or retract downward along the axial direction of the burner 11 via the connecting rod 44. Thus, when controlling the detection position of the dry-burn detection module 22 according to the cooking indicator of the cookware, the anti-dry-burn control module 24 can output a drive control signal to control the rotation of the motor 432. The motor 432 drives the output shaft 431 to extend upward or retract downward, causing the output shaft to drive the dry-burn detection probe 221 of the dry-burn detection module 22 to move via the connecting rod 44, thereby improving the flexibility of the anti-dry-burn control system.

[0070] Optionally, referring to Figure 2, the anti-dry-burning control system of the gas stove also includes: at least one cookware detection module 21 corresponding to the burner 11; the cookware detection module 21 is used to acquire cookware detection information at the burner 11; the anti-dry-burning control module 24 is also connected to the cookware detection module 21.

[0071] Specifically, before the cooking detection module 23 obtains the cooking indicator of the cookware heated by the burner 11, the anti-dry-burning control module 24 can also control the opening or closing of the cookware detection module 21. When the cookware detection module 21 is turned on, the anti-dry-burning control module 24 can receive the cookware detection information obtained by the cookware detection module 21 and determine whether there is a cookware placed at the burner 11 based on the cookware detection information. When there is a cookware placed at the burner 11, the cooking detection module 23 can be turned on to prevent the dry-burning detection function 22 from being turned on even when there is no cookware on the gas stove, thus avoiding resource waste and improving the service life of the dry-burning detection module 22.

[0072] Optionally, referring to Figures 1 to 7, the cookware detection module 21 may include a magnetic module 211, a magnetic detection module 212, and a magnetically conductive structure 213 located between the magnetic module 211 and the magnetic detection module 212. The magnetically conductive structure 213 may include a magnetically conductive part 2131 and a non-magnetically conductive part 2132. The magnetically conductive structure 213 may be an integral structure with the dry-burning detection probe 221, or the magnetically conductive structure 213 may serve as a support for the dry-burning detection probe 221, so that when no cookware is placed at the burner 11, the dry-burning detection probe 221 will not be pressed down. At this time, the non-magnetically conductive part 2132 of the magnetically conductive structure 213 is located between the magnetic module 211 and the magnetic detection module 212, so that the magnetism generated by the magnetic module 211 cannot be transmitted to the magnetic detection module 212, and the magnetic detection module 212 cannot detect magnetism with a certain intensity. When the detection result is fed back to the anti-dry-burning control module 24, the anti-dry-burning control module 24 can... The system determines that no cookware is placed at burner 11. Conversely, when cookware is placed at burner 11, the dry-burn detection probe 221 is pressed down by the pressure from the bottom of the cookware, causing the magnetic conductive structure 213 to move. This positions the magnetic conductive part 2131 of the magnetic conductive structure 213 between the magnetic module 211 and the magnetic detection module 212. The magnetism generated by the magnetic module 211 is then transmitted to the magnetic detection module 212 through the magnetic conductive part 2131. The magnetic detection module 212 detects magnetism of a certain intensity. When this detection result is fed back to the anti-dry-burn control module 24, the anti-dry-burn control module 24 can determine that cookware is placed at burner 11. By combining the cookware detection module 21 and the dry-burn detection module 22, the overall structure of the gas stove's anti-dry-burn control system 20 is simplified, thereby reducing its size and cost.

[0073] It should be noted that, in this embodiment, the gas stove includes at least one burner, and the anti-dry-burning control system of the gas stove may include at least one cookware detection module and at least one dry-burning detection module. That is, the number of cookware detection modules and dry-burning detection modules can also be one or more, and the number of cookware detection modules and dry-burning detection modules can be the same as or different from the number of burners in the gas stove. For example, when the gas stove includes two burners, the number of cookware detection modules and dry-burning detection modules can be 1 or 2. When the number of cookware detection modules and dry-burning detection modules is 1, the cookware detection modules and dry-burning detection modules can be set at the burner commonly used for cooking methods such as steaming or boiling as needed. The specific design can be made according to actual needs, and this embodiment of the invention does not make specific limitations in this regard.

[0074] Optionally, referring back to Figure 2, the cooking detection module 23 may include a visual detection device. This device can acquire image information of the pot placed on the burner and determine the cooking indicator of the pot based on the image information. When this cooking indicator is fed back to the anti-dry-burning control module 24, the anti-dry-burning control module 24 can determine the current cooking mode of the pot based on the cooking indicator. The cooking detection module 23 can be located anywhere that can acquire cooking information of the pot on the burner; this embodiment of the invention does not specifically limit its location.

[0075] In an optional embodiment, as shown in Figures 8 and 9, the gas stove 10 is typically used in conjunction with a range hood 30, which is positioned opposite to the gas stove 10 so that the fumes generated during cooking on the gas stove 10 can be exhausted by the range hood 30. In this case, the cooking detection module 23 can be mounted on the range hood 30, allowing the cooking detection module 23 to have a relatively fixed position, preventing inaccurate detection of the cookware on the burner 11 due to changes in the detection angle, distance, etc. of the cooking detection module 23.

[0076] Optionally, referring to Figures 1 to 9, the anti-dry-burning control module 24 is connected to the cookware detection module 21, the dry-burning detection module 22, the cooking detection module 23, and the drive mechanism 25, respectively. The specific connection method may include, but is not limited to, wire connection or wireless communication connection. The specific implementation method can be designed according to actual needs, and the embodiments of the present invention do not specifically limit it.

[0077] In an optional embodiment, referring to Figures 1 to 9, the anti-dry-burning control module 24 and the cooking detection module 23 are wirelessly connected. The specific communication method may include, but is not limited to, WIFI, Bluetooth, ZigBee, etc. The cookware detection module 21 and the dry-burning detection module 22 are pluggably connected to the anti-dry-burning control module 24 through different wiring terminals (214, 222), so as to facilitate the maintenance and replacement of the cookware detection module 21 and the dry-burning detection module 22, and improve the overall service life of the gas stove 10.

[0078] Furthermore, the anti-dry-burning control module 24 can be integrated into the controller of the gas stove 10, or it can be integrated into the controller of the range hood 30, or it can exist independently. When the anti-dry-burning control module 24 is integrated into the controller of the range hood 30, it is also connected to the controller of the gas stove 10 to send corresponding control signals to the controller of the gas stove 10, enabling the controller of the gas stove 10 to control the corresponding burner 11 to turn on or off. Provided that the core inventive points of this embodiment are achieved, this embodiment does not limit the specific configuration of the anti-dry-burning control module 24.

[0079] It is understood that the anti-dry-burning control module provided in the embodiments of the present invention can be used to execute the anti-dry-burning control method of the gas stove provided in the embodiments of the present invention. Therefore, in the embodiments of the present invention, the anti-dry-burning control module has a module for executing the anti-dry-burning control method of the gas stove provided in any embodiment of the present invention. The specific execution process will be described below and will not be repeated here.

[0081] This embodiment provides a method for preventing dry burning in a gas stove. This method can improve the service life of the dry burning detection module and reduce the cost of the gas stove. The method provided in this embodiment can be executed by the anti-dry burning control module in the anti-dry burning control system of the gas stove provided in this embodiment. The anti-dry burning control module can be composed of software and / or hardware. As shown in Figure 10, the method for preventing dry burning in this embodiment includes:

[0082] S110. When the burner is started to heat the cookware, the cooking identifier of the cookware heated by the burner is obtained based on the cooking detection module.

[0083] The cooking identifier may include features of the cookware itself or features of the food being cooked in the cookware. When the cooking identifier includes features of the cookware itself, it may include at least one external feature of the cookware, such as a handle, lugs, sidewalls, or depth, so that the type of cookware can be determined by its external features, thereby determining the current cooking mode. In one exemplary embodiment, cookware used for steaming or boiling typically has two symmetrically arranged lugs, while cookware used for stir-frying typically has a longer handle, or a longer handle and a lug corresponding to the handle. Thus, the cooking mode that may be achieved when using the cookware can be determined based on the arrangement of the lugs. In another exemplary embodiment, cookware used for steaming or boiling typically has a greater depth and / or steeper sidewalls. By obtaining the depth and / or the steepness of the sidewalls, it can be determined whether the cookware is used for steaming or boiling, thereby determining the current cooking mode based on the type of cookware. When the cooking label includes a characteristic label of the food being cooked in the pot, the cooking label may include the type of food, the color of the food, and other appearance characteristics of the food, so as to determine the current cooking mode by the type of food and / or the color of the food. For example, if there is a large amount of liquid in the food in the pot and / or the color of the food changes slowly, it can be determined that the pot is steaming or boiling, and the current cooking method can be determined based on this.

[0084] It should be noted that the above description only provides an exemplary illustration of how to determine the current cooking method when the cooking identifier includes the characteristic identifier of the food being cooked inside the pot or the characteristic identifier of the pot itself. In the embodiments of the present invention, the current cooking method can also be determined based on both the characteristic identifier of the food being cooked inside the pot and the characteristic identifier of the pot itself. Provided that accurate detection of the current cooking method of the pot can be achieved, the embodiments of the present invention do not impose specific limitations on this.

[0085] Furthermore, starting the burner to heat the cookware can be understood as the burner igniting and the cookware being placed on it, allowing the burner to heat the cookware and thus enabling the cooking of food. When the burner is activated to heat the cookware, a corresponding cooking detection module can be activated, enabling the module to acquire the cooking status of the cookware. Activating the cooking detection module can be understood as providing a power signal to it. For example, a switch can be installed between the cooking detection module and the power module providing the power signal. By controlling this switch to open, the power signal output from the power module can be transmitted to the cooking detection module, enabling the module to start operating and acquire the cooking status of the cookware being heated by the burner in real time.

[0086] In an optional embodiment, after acquiring the cooking identifier of the cookware, the cooking detection module can be controlled to be in a closed state, so that there is no need to provide a power signal to the cooking detection module, thereby reducing power consumption, achieving energy saving, and meeting the needs of economy.

[0087] S120. Control the detection position of the dry-burn detection module according to the cooking markings on the cookware.

[0088] The dry-burn detection module can be configured to operate in a working position or not. When the dry-burn detection module is in a non-working position, the cookware is outside the detection range of the module, so that the module is not exposed to heat radiated by the cookware. When the module is in a working position, the cookware is within the detection range, allowing the module to detect whether the cookware is dry-burning.

[0089] Specifically, the cooking method is determined by the cooking markings on the cookware, and the dry-burn detection module is positioned differently depending on the cooking method. When the dry-burn detection function needs to be activated, the module is brought closer to the cookware to detect dry-burning conditions; when the function is not needed, the module is moved away from the cookware to prevent it from being exposed to high temperatures for extended periods.

[0090] In an exemplary embodiment, taking the cooking identifier of the cookware, which includes the cookware's own characteristic identifier, as an example, when the cookware is determined to be a steamer or a boiling pot based on its cooking identifier, the current cooking method is likely steaming or boiling. In this case, the dry-burn detection module is controlled to move closer to the cookware to detect the dry-burning status of the steamer or boiling pot. When the cookware is determined to be a wok based on its cooking identifier, the current cooking method is likely frying, and there is no need to detect the dry-burning status of the wok. In this case, the dry-burn detection module is controlled to move away from the cookware. In this way, while accurately detecting dry-burning, the dry-burn detection module can be prevented from being in a high-temperature environment for a long time, which would affect its service life. This is beneficial to improving the overall service life of the gas stove and meeting the requirements of economy and reliability.

[0091] Optionally, the detection position of the dry-burn detection module can be controlled according to the cooking markings on the cookware. Specifically, this may include: determining whether the cooking method of the cookware is a preset method based on the cooking markings on the cookware; if not, controlling the dry-burn detection module to be in a non-working position; if so, controlling the dry-burn detection module to be in a working position.

[0092] The preset methods may include, but are not limited to, steaming or boiling.

[0093] Specifically, the cooking method of the cookware can be determined based on its cooking markings. If the cooking method is a preset mode, such as steaming or boiling, the dry-burn detection module can be extended from the center of the burner and raised to a preset height, putting it in the working position. The cookware is then within the detection range of the dry-burn detection module, allowing it to detect whether the cookware is dry-burning. Conversely, if the cooking method is not a preset mode, such as stir-frying, the dry-burn detection module can be lowered to a preset height, retracting into the center of the burner. This puts it in a non-working position, and the cookware is no longer within its detection range, so the module no longer detects whether the cookware is dry-burning. In this way, the detection position of the dry-burn detection module can be controlled to be in the working or non-working position according to the specific cooking method of the cookware. This allows the position of the dry-burn detection module to be adjusted as needed. When the dry-burn detection module is not needed to work, it can avoid the dry-burn detection module being in a high-temperature environment for a long time, thus improving the service life of the dry-burn detection module.

[0094] In an exemplary embodiment, when the cooking identifier of the cookware includes its own feature identifier, the feature identifier of the cookware itself may include, for example, the lug feature of the cookware. The cooking identifier of the cookware obtained based on the cooking detection module may include an image of the lug of the cookware. If it is determined from the lug image that the cookware includes one lug or has no lug (as shown in Figure 11), it can be determined that the cookware is not a cookware for cooking methods such as steaming or boiling. At this time, it can be determined that the cooking method of the cookware is not the preset method, and the dry-burning detection module can be controlled to remain in a non-working position, without needing to check whether the cookware is dry-burning. The cookware is outside the detection range of the dry-burning detection module, and the dry-burning detection module will not detect it. Detecting the heat radiated by the cookware prevents the electronic components in the dry-burn detection module from being exposed to high temperatures for extended periods, thus extending their lifespan. Conversely, if the image of the cookware's lugs indicates that it includes two symmetrically arranged lugs (as shown in Figure 12), it can be determined that the cookware is designed for steaming, boiling, or other cooking methods. In this case, the cooking method can be set to the preset mode, allowing the dry-burn detection module to remain continuously operational. This real-time detection of dry-burning issues prevents potential safety hazards caused by dry-burning, thereby improving the safety and stability of the gas stove.

[0095] Optionally, the anti-dry-burning control method for gas stoves also includes: when the burner is started and ignited, controlling the dry-burning detection module corresponding to the burner to be in the working position.

[0096] When the dry-burn detection module is in the working position, the cookware is within its detection range. Thus, when the burner is turned on, the dry-burn detection module extends from the center of the burner and rises to a preset height, placing it in the working position. This allows for direct detection of the cookware's dry-burn status without needing to adjust the module's position, improving the safety and stability of the gas stove.

[0097] In other alternative embodiments, the method for preventing dry burning of the gas stove further includes: controlling the dry burning detection module to be in a non-working position after the burner is turned off.

[0098] When the dry-burn detection module is in the non-operating position, the cookware is outside the detection range. Thus, after the burner is turned off, the user is assumed to have finished cooking and stopped using the gas stove. At this point, there is no need to perform dry-burn detection on the cookware. The dry-burn detection module can be lowered to a preset height, retracting into the center of the burner, placing it in the non-operating position. This prevents damage from external impacts and provides some protection for the dry-burn detection module, extending its lifespan.

[0099] This embodiment obtains the cooking indicator of the cookware when the burner is activated and the cookware is heated, based on the cooking detection module. The detection position of the dry-burn detection module is controlled according to this indicator, allowing for on-demand adjustment of the module's position. When the dry-burn detection module is needed, it can detect dry burning of the cookware, improving the safety and stability of the gas stove. When the dry-burn detection module is not needed, it avoids the burner heating the cookware, preventing it from remaining at a high temperature and thus extending the lifespan of the module's built-in electronic components. This reduces the cost of the gas stove and meets the needs of economic and energy-saving practices.

[0100] Example 3

[0101] This embodiment describes a method for detecting whether a cookware is dry-burning when the dry-burning detection module is in the working position, based on the above embodiments. As shown in Figure 13, the anti-dry-burning control method for gas stoves in this embodiment includes:

[0102] S210. When the burner is started to heat the cookware, the cooking identifier of the cookware heated by the burner is obtained based on the cooking detection module.

[0103] S220. Based on the cooking markings on the cookware, determine whether the cooking method of the cookware is the preset method; if not, proceed to S230; if yes, proceed to S240 to S260 in sequence.

[0104] S230, the dry burning detection module is in a non-working position.

[0105] S240, the dry burning detection module is in the working position.

[0106] S250: Based on the dry burning detection module, the temperature information of the pot being heated at the burner corresponding to the dry burning detection module is obtained in real time.

[0107] The dry-burn detection module may include, but is not limited to, a temperature sensor. When the dry-burn detection module is in the working position, the temperature sensor can contact the bottom of the cookware to detect the temperature information of the cookware in real time. Conversely, when the dry-burn detection module is not in the working position, the temperature sensor can be retracted into the burner, so that the temperature sensor does not contact the bottom of the cookware. This protects the temperature sensor from the heat radiated by the cookware, preventing the dry-burn detection module from being in a high-temperature environment for a long time and thus extending its service life.

[0108] In an optional embodiment, the dry-burn detection module's detection of the cookware's temperature information can be understood as follows: the dry-burn detection module contacts the center of the cookware's bottom, allowing it to acquire the temperature at the center of the cookware's bottom in real time, and generate corresponding temperature information based on this temperature. Compared to detecting the temperature at the edge of the cookware, the temperature at the center of the bottom is closer to the actual temperature inside the cookware. Therefore, by detecting the temperature at the center of the cookware's bottom in real time, the temperature of the cookware can be determined more accurately.

[0109] S260. Based on the temperature information of the cookware, control the working state of the burner where the cookware is located.

[0110] Specifically, when a cookware becomes dry-burned, its temperature will rise compared to when it is not dry-burning. Based on the temperature information obtained by the dry-burning detection module, the cookware temperature can be determined. This temperature reading can then be used to determine if the temperature rise is abnormal, thus identifying whether dry-burning has occurred. If dry-burning is confirmed based on the cookware temperature information, the burner can be shut off to prevent further dry-burning and potential safety hazards, thereby improving the safety of the gas stove. Conversely, if dry-burning is not confirmed based on the cookware temperature information, the burner can remain on to continue heating the food in the cookware.

[0111] In an optional embodiment, controlling the working state of the burner where the cookware is located based on the temperature information of the cookware may include: determining the temperature rise rate of the cookware at the current moment based on the acquired temperature information of the cookware at various times; determining whether the temperature rise rate at the current moment is greater than or equal to a preset rate; if so, controlling the burner where the cookware is located to turn off the flame.

[0112] Specifically, when the cookware is being cooked normally without dry-heating, because there is a relatively large amount of liquid inside, the cookware will slowly heat up to the boiling point of the liquid during the heating process. After reaching the boiling point, the liquid inside the cookware will evaporate, but the temperature of the cookware will remain relatively stable, meaning that the temperature of the cookware will not change significantly. At this time, the temperature rate of the cookware can be determined based on the temperature information obtained at each moment, which is a relatively small value. However, when the cookware is dry-heating, the liquid inside the cookware is completely evaporated, and the temperature of the cookware will rise further, causing the temperature of the cookware to change more significantly. At this time, the temperature rise rate of the cookware determined based on the temperature information obtained at each moment is a relatively large value. In this way, the temperature rise rate of the cookware can be determined by the temperature information of the cookware at various times, and it can be judged whether the temperature rise rate is greater than or equal to the preset rate. If the temperature rise rate of the cookware is greater than or equal to the preset rate, it indicates that the temperature of the cookware is rising too fast, and the cookware may be dry-burning. At this time, the burner of the cookware can be turned off to prevent safety hazards caused by further temperature rise of the cookware, thereby improving the safety of the gas stove. If the temperature rise rate of the cookware is less than the preset rate, it indicates that the temperature of the cookware is changing slowly. At this time, the liquid in the cookware may be in a normal heating or boiling state, and the cookware is not dry-burning. In order to continue heating the food in the cookware, the burner can be kept on.

[0113] In other optional embodiments, the working state of the burner where the cookware is located is controlled according to the temperature information of the cookware, including: determining whether the temperature of the cookware at the current moment is greater than a preset temperature according to the temperature information of the cookware at the current moment; if so, controlling the burner where the cookware is located to turn off the flame.

[0114] When steaming or boiling is the cooking method, the pot contains a large amount of liquid, usually water. Water typically boils at 100°C under normal pressure. Since pots are usually made of metal, their melting point is much higher than water's boiling point under normal pressure. Therefore, after the liquid evaporates, continued heating will cause the pot's temperature to rise significantly, exceeding the boiling point of water. By monitoring the pot's temperature in real time and determining its current temperature, if it exceeds a preset temperature, it's possible the liquid has completely evaporated, resulting in dry burning. To prevent further temperature increases and potential safety hazards, the burner can be turned off, improving the safety of the gas stove. Conversely, if the pot's temperature is below or equal to the preset temperature, the liquid is heating normally, and the burner can be kept on to continue heating the food until it is cooked. For example, the preset temperature can be a temperature greater than or equal to approximately 100°C, such as 120°C, 150°C, or 200°C.

[0115] In an optional embodiment, when the cookware is dry-burned and the burner is turned off, a warning reminder can be issued. This warning reminder may include, but is not limited to, at least one of voice reminders, buzzer reminders, and light reminders, so that the user can be informed of the working status of the burner in the gas stove in a timely manner and take appropriate countermeasures, thereby improving the safety of using the gas stove.

[0116] This embodiment controls the dry-burn detection module at the burner to be in the working position when the cooking mode of the cookware is determined to be a preset mode based on the cooking indicator of the cookware heated by the burner. When the cooking mode of the cookware is not a preset mode, the dry-burn detection module at the burner is controlled to be in the non-working position. This avoids the dry-burn detection module being in a high-temperature environment for a long time, thereby improving the service life of the dry-burn detection module, reducing the cost of the gas stove, and meeting the requirements of economy. In addition, when the dry-burn detection module is in the working position, the temperature information of the cookware can be obtained through the dry-burn detection module, and the working state of the burner can be controlled according to the temperature information of the cookware. This allows the burner to be shut off in time when dry-burning is determined based on the temperature information of the cookware, avoiding safety hazards and improving the safety and stability of the gas stove.

[0117] Example 4

[0118] Based on the above embodiments, the gas stove anti-dry-burning control system further includes at least one cookware detection module corresponding to the burner. This embodiment describes the implementation method for determining whether a cookware is placed at the burner, as shown in Figure 14. The gas stove anti-dry-burning control method of this embodiment includes:

[0119] S310. When the burner is started and ignited, the cookware detection information at the burner is obtained based on the cookware detection module.

[0120] Specifically, when a user needs to cook food using a gas stove, the corresponding burner is ignited via a switch on the stove, changing the burner from an off state to an on state – this is called igniting the burner. At this time, a pot may or may not be placed on the burner due to other factors. By activating the pot detection module, information is obtained regarding whether a pot is placed on the burner. This pot detection information can include any information used to distinguish whether a pot is placed on the burner, such as magnetic strength information or electrical signal strength information.

[0121] For example, as shown in Figure 7, taking a dry-burning detection module including a dry-burning detection probe 221, a cookware detection module including a magnetic module 211, a magnetic detection module 212, and a magnetically conductive structure 213 located between the magnetic module 211 and the magnetic detection module 212 as an example, in this case, by obtaining the magnetic intensity detected by the magnetic detection module 213, it can be determined whether the magnetically conductive structure 213 transmits the magnetism generated by the magnetic module 211 to the magnetic detection module 213. Thus, the cookware detection information can include magnetic intensity information. Based on the magnetic intensity information, the magnetic intensity detected by the magnetic detection module 213 can be determined. When the magnetic intensity is greater than or equal to a preset intensity, it can be determined that a cookware is placed at the burner, and when the magnetic intensity is less than the preset intensity, it can be determined that no cookware is placed at the burner.

[0122] As can be understood, as shown in Figure 7, since the dry-burn detection probe 221 and the cookware detection module are integrated, when the burner is started, in order for the cookware detection module to accurately obtain cookware detection information, the dry-burn detection probe 221 can be controlled to be in the working position, that is, the dry-burn detection probe extends out of the burner, so that when a cookware is placed on the burner, the dry-burn detection probe can contact the cookware and be subjected to the pressure of the cookware, thereby enabling the cookware detection module to accurately detect whether a cookware is placed at the burner.

[0123] In addition, turning on the cookware detection module can be understood as providing a power signal to the cookware detection module. For example, a corresponding switch can be set between the cookware detection module and the power module that provides the power signal. By controlling the switch to turn on, the power module can provide a power signal to the cookware detection module, enabling the cookware detection module to start working and obtain cookware detection information in real time.

[0124] In an optional embodiment, when the burner is in the off state, the cookware detection module corresponding to the burner can be in the off state. At this time, there is no need to provide a power signal to the cookware detection module, which helps to save energy and meet the needs of economy.

[0125] S320. When it is determined from the cookware detection information that the burner is heating the cookware, the cooking identifier of the cookware heated by the burner is obtained based on the cooking detection module.

[0126] Specifically, based on the cookware detection information, it can be determined whether a cookware is placed at the burner. When a cookware is placed at the burner, it can be determined that the burner is heating the cookware. In this case, the cooking detection module can obtain the cooking identifier of the cookware being heated by the burner, so as to control the detection position of the dry-burning detection module according to the cooking identifier of the cookware. When it is determined from the cookware detection information that no cookware is placed at the burner, it can be determined that the burner is not heating the cookware, so the cooking detection module cannot obtain the corresponding cooking identifier. In this case, it is not necessary to start the cooking detection module to obtain the cooking identifier of the cookware, and the cooking detection module can be controlled to be in a closed state. This helps to reduce the power consumption of the gas stove's anti-dry-burning control system and meet the needs of energy saving and economy.

[0127] S330: Control the detection position of the dry-burn detection module according to the cooking markings on the cookware.

[0128] This embodiment allows the cookware detection module to activate when the burner switches from an off state to an on state. Based on the cookware detection module's information, it can determine whether a cookware is placed at the burner. When the burner is determined to be heating a cookware, the cooking detection module activates and acquires the cookware's cooking indicator. Based on this indicator, the corresponding dry-burning detection module is positioned accordingly. This cookware detection module prevents the anti-dry-burning detection function from being falsely triggered when no cookware is placed on the gas stove, thus improving the accuracy of dry-burning detection, meeting energy-saving requirements, enhancing user experience, and extending the module's lifespan.

[0129] Example 5

[0130] This embodiment, based on the above embodiment, explains how to control the burner's heat when it is determined from cookware detection information that the burner is not heating the cookware. As shown in Figure 15, the anti-dry-burning control method for the gas stove in this embodiment includes:

[0131] S410. When the burner is started and ignited, the cookware detection information at the burner is obtained based on the cookware detection module.

[0132] S420. When it is determined that the burner is heating the cookware based on the cookware detection information, the cooking identifier of the cookware heated by the burner is obtained based on the cooking detection module.

[0133] S430. Control the detection position of the dry-burn detection module according to the cooking markings on the cookware.

[0134] S440. When it is determined from the cookware detection information that the burner is not heating the cookware, the burner is controlled to adjust from the working firepower to the preset firepower, and the idle time when the burner is not heating the cookware is timed.

[0135] The preset heat setting can be the minimum heat setting of the burner, for example, it can be less than or equal to the operating heat setting. At the preset heat setting, the burner burns less fuel per unit time, which is beneficial for energy conservation and emission reduction. At the same time, when the burner is at its minimum heat setting, its heating speed is slower, which can avoid the occurrence of corresponding safety hazards and ensure the safety and stability of the gas stove.

[0136] Specifically, after the burner is started and ignited, due to objective or subjective factors, the cookware detection module may not detect any cookware placed at the burner in the cookware detection information it obtains. In this case, the burner's firepower can be adjusted from the working firepower at startup to a preset firepower with a smaller firepower, thereby achieving the effect of energy saving and emission reduction.

[0137] S450. Determine whether the current idle time is greater than or equal to the preset time; if yes, execute S460; if no, return to execute S410.

[0138] The preset time can be designed according to actual needs. The preset time can be the time when the pot is briefly removed from the burner. For example, the preset time can be less than or equal to 1 minute. In an exemplary embodiment, the preset time can be 40 seconds.

[0139] S460, Control burner to shut off.

[0140] S470. When it is determined from the cookware detection information that the burner is heating the cookware, the firepower of the burner is adjusted from the preset firepower to the working firepower, and then the process returns to execute S420.

[0141] Specifically, after adjusting the burner's heat to the preset level, the time the gas stove maintains the preset heat can be recorded. This involves timing the idle time when the burner is not heating the cookware, and determining whether this idle time has reached the preset time. If the current idle time reaches the preset time (i.e., the current idle time is greater than or equal to the preset time), it indicates that the burner has not been heating the cookware for an extended period. To prevent safety hazards and resource waste, the burner can be shut off. If the current idle time is less than the preset time, the cookware detection module can be used to re-obtain cookware detection information at the burner. This information is then used to further check whether the burner is heating the cookware. If the cookware is still not being heated, the burner can continue to maintain the preset heat until the current idle time reaches the preset time, at which point the burner is shut off, and the cookware detection module is also turned off. Conversely, if the current idle time is less than the preset time, and the cookware detection module is used to re-obtain cookware detection information, the burner can continue to maintain the preset heat until the current idle time reaches the preset time, at which point the burner is shut off, and the cookware detection module is turned off. After detecting the cookware at the burner, the system determines that the burner is heating the cookware. The burner's heat can then be adjusted from the preset heat to the operating heat, such as the heat at the start of the burner or the heat last adjusted by the user, ensuring proper heating. Upon detecting a cookware again at the burner, to prevent changes in the cookware's cooking indicator due to user changes or additions, the cooking detection module needs to be activated again to retrieve the cookware's cooking indicator. Based on this re-acquired indicator, the cooking mode at the burner is determined. If the cooking mode is detected as a preset mode such as steaming or boiling, the dry-burn detection module can be activated; otherwise, it remains closed.

[0142] Based on the above embodiments, when the burner is turned off after a preset time of idle time, a warning reminder can also be given. This warning reminder may include, but is not limited to, at least one of voice reminder, buzzer reminder, and light reminder, so that users can be informed of the working status of the burner in the gas stove in a timely manner and take corresponding measures to improve the safety of using the gas stove.

[0143] It is understandable that, apart from the aforementioned situations where the cookware shuts off due to dry burning or reaching a preset idle time, warnings can be issued for all non-user-manually shut-off scenarios. For example, when a cooking time is set, a warning can be issued after the set cooking time is reached, so that the user can be promptly notified that cooking has ended normally. Furthermore, the warning methods for these scenarios can be the same or different, and can be designed according to actual needs; this embodiment of the invention does not impose specific limitations on this. In an optional embodiment, to differentiate between different shut-off scenarios, different warnings can be issued in different situations. For example, different scenarios can involve different voice prompts, different light activations, or different beep frequencies.

[0144] This embodiment, by determining, based on cookware detection information obtained from the cookware detection module, that the burner is not heating the cookware when it is activated, can adjust the burner's heat from the operating heat to a preset heat, keeping the heat at a lower level. This improves the safety of the gas stove and promotes energy conservation and emission reduction. Simultaneously, when it is determined that the burner is not heating the cookware, the idle time is timed. When the preset idle time is reached, the burner can be shut off promptly to prevent energy waste and safety hazards caused by prolonged periods of inactivity. Conversely, if the preset idle time is not reached, the cookware detection information can be retrieved again. If the retrieved information indicates that the burner will resume heating the cookware, the burner can be adjusted back from the preset heat to the operating heat to ensure proper heating and successful cooking.

[0145] Example 6

[0146] This invention also provides a gas stove anti-dry-burning control device. This device can accurately detect dry burning while improving the lifespan of the dry-burning detection module. It can execute the gas stove anti-dry-burning control method provided in any embodiment of this invention. The device can be implemented using hardware and / or software and can be integrated into the anti-dry-burning control module of the gas stove's anti-dry-burning control system. As shown in Figure 16, the gas stove anti-dry-burning control device includes: a cooking detection control module 520 and a dry-burning detection control module 530, wherein:

[0147] The cooking detection control module 520 is used to obtain the cooking identifier of the cookware heated by the burner based on the cooking detection module when the burner is started to heat the cookware.

[0148] The dry-burn detection control module 530 is used to control the detection position of the dry-burn detection module according to the cooking markings on the cookware.

[0149] Optionally, the dry-burn detection control module 530 is specifically used to: determine whether the cooking mode of the cookware is a preset mode based on the cooking indicator of the cookware; if yes, control the dry-burn detection module to be in the working position; if no, control the dry-burn detection module corresponding to the burner to be in the non-working position.

[0150] Optionally, the anti-dry-burning control device of the gas stove also includes a temperature acquisition module and a burner control module. The temperature acquisition module is used to acquire the temperature information of the pot being heated at the burner corresponding to the dry-burning detection module in real time after the dry-burning detection module is turned on. The burner control module is used to control the working state of the burner where the pot is located according to the temperature information of the pot.

[0151] Optionally, the burner control module is specifically used to: determine the temperature rise rate of the cookware at the current moment based on the acquired temperature information of the cookware at various times; determine whether the temperature rise rate at the current moment is greater than or equal to the preset rate; if so, control the burner where the cookware is located to turn off.

[0152] Optionally, the burner control module is specifically used to: determine whether the temperature of the cookware at the current moment is greater than the preset temperature based on the temperature information of the cookware at the current moment; if so, control the burner of the cookware to turn off.
