[0037] refer to Figure 1 and Figure 2 In a first aspect, this utility model provides a stove fire control device applied to a stove body 10, the stove body 10 having a stove 11 and a fire switch 30; the stove fire control device includes a pot detection mechanism 20 disposed on the stove body 10.

[0038] The cookware detection mechanism 20 is used to detect whether there is a cookware on the stove 11; based on the cookware status information detected by the cookware detection mechanism 20, the fire switch 30 is set to either the on or off state.

[0039] Specifically, the stove body 10 includes a stove 11 and a fire switch 30. The ignition state and firepower of the stove 11 can be controlled according to the operating state of the fire switch 30. The operating states of the fire switch 30 include an on state, a closed state, and different opening degrees. For example, when the fire switch 30 is on, it can ignite the stove 11; when it is off, it can turn off the stove 11. Rotating the fire switch 30 adjusts its opening degree, thereby adjusting the firepower of the stove 11. Different opening degrees correspond to different firepower values, and the opening degree can be adjusted from 0% to 100%.

[0040] The cookware detection mechanism 20 is installed on the burner rack of the stove 11 to detect whether a cookware is placed on the stove 11. Based on the cookware status information detected by the cookware detection mechanism 20, the flame switch 30 can be switched between the on and off states, so that the flame switch 30 can be in either the on or off state. This allows the system to determine whether to ignite the stove 11 based on the cookware status information detected by the cookware detection mechanism 20, thus avoiding the waste of gas resources caused by ignition when no cookware is placed, and avoiding the risk of burns to the operator from flames. In particular, it can prevent the risk of children being burned by accidentally operating the flame switch 30.

[0041] This application does not specifically limit the type and material of the cookware. Those skilled in the art can set it according to actual needs. For example, the cookware includes frying pans, woks, saucepans, steamers, milk pots, etc. The material of the cookware is iron, aluminum, or stainless steel, etc.

[0042] The stove fire control device provided in this application embodiment has a simple structure and is easy to operate. It can control the working state of the fire switch 30 according to the pot status information detected by the pot detection mechanism 20. It can avoid the waste of gas resources caused by ignition when no pot is placed, and avoid the danger of flames shooting out and causing burns to the operator, thereby improving the safety of using the stove 11.

[0043] In some embodiments, the cookware detection mechanism 20 is determined to be in a detection state based on the operating state of the fire switch 30.

[0044] Specifically, when the fire switch 30 is in the on state (or ignition state), i.e., in response to the trigger operation of the fire switch 30, the cookware detection mechanism 20 detects whether there is a cookware on the stove 11. The trigger operation can be manually rotating the knob of the fire switch 30, or controlling the fire switch 30 to turn on via a touch operation on the control panel 50, or controlling the fire switch 30 to turn on via a touch operation on a mobile terminal. For example, when the knob of the fire switch 30 is manually rotated to turn on the ignition needle 31 for ignition, the controller 40 controls the cookware detection mechanism 20 to start detecting whether there is a cookware on the stove 11. The cookware detection mechanism 20 only starts performing the detection work according to the trigger operation of the fire switch 30, avoiding the cookware detection mechanism 20 being in a continuous working state, reducing power consumption, and extending the service life of the cookware detection mechanism 20.

[0045] In some embodiments, the cookware detection mechanism 20 includes a reed switch, a magnetic sensor, and a weighing device.

[0046] Specifically, a reed switch, a magnetic sensor, and a weighing device can be installed on the stove rack of the stove 11. The reed switch consists of a glass tube, two reeds, and a filling gas. The magnetic changes of the reeds can control the conduction state of the reed switch through the action of an external magnetic field. The principle of the reed switch is based on the magnetic changes of the reeds. When an external magnetic field acts on the reed switch, the reeds are affected by the magnetic force and bend, causing the two ends of the reeds inside the tube to contact each other, thus closing the circuit inside the tube. When the external magnetic field disappears, the reeds return to their original shape, and the circuit inside the tube is broken. When a magnetic cookware is near the stove 11, the circuit inside the reed switch is closed, indicating that a cookware is placed on the stove 11; conversely, when the magnetic cookware is away from the stove 11, the circuit inside the reed switch is broken, indicating that no cookware is placed on the stove 11.

[0047] The magnetic sensor uses the change in magnetic field when a pot is placed on the stove 11 to determine whether a pot is placed on the stove 11.

[0048] Weighing devices, such as electronic scales, determine whether a pot is placed on the stove 11 based on the weight of the pot being detected. If the detected weight of the pot reaches a preset weight threshold, it is considered that a pot is placed on the stove 11. The preset weight threshold is generally the weight information of the pot, such as the weight of a wok is generally 3kg~4kg, and the weight of a steamer is 1-5kg, etc. Operators, such as cooks, can set the preset weight threshold for the pots based on the weight of their commonly used pots.

[0049] In some embodiments, the fire switch 30 includes an electric valve or a pneumatic valve.

[0050] Specifically, the fire switch 30 is generally installed on the stove body 10. The fire switch 30 is an electric valve or a pneumatic valve. The electric valve or pneumatic valve can open the ignition needle 31 to perform ignition operation, close the ignition needle 31 to perform flame-off operation, and adjust the fire value of the stove 11 by controlling the opening degree of the electric valve or pneumatic valve.

[0051] In some embodiments, when the cookware detection mechanism 20 detects that no cookware is placed on the stove 11, the fire switch 30 is in the off state.

[0052] When the cookware detection mechanism 20 detects that a cookware is placed on the stove 11, the fire switch 30 is in the on state.

[0053] Specifically, when the flame switch 30 knob is manually rotated to turn on the ignition needle 31 for ignition, if the cookware detection mechanism 20 detects that a cookware is placed on the stove 11, the flame switch 30 is kept on, and ignition is successful. Conversely, if no cookware is detected, the flame switch 30 is kept off, and ignition is not performed. This reduces the risk of children or the elderly accidentally operating the flame switch 30 knob, causing flames to erupt from the stove 11 and burn them, and also avoids wasting gas resources due to ignition when no cookware is placed on the stove.

[0054] In some embodiments, while the cookware is in the cooking state, the operating state of the fire switch 30 is determined based on the cookware status information and the duration of no cookware detected by the cookware detection mechanism 20. The operating state of the fire switch 30 includes an on state, a closed state, and different opening degrees.

[0055] Specifically, after the stove 11 is successfully ignited and the pot is cooking, the pot detection mechanism 20 periodically checks whether the pot on the stove 11 has been removed. If the pot detection mechanism 20 detects that there is no pot on the stove 11, it means that the pot has been removed from the stove 11; conversely, if the pot detection mechanism 20 detects that there is a pot on the stove 11, it means that the pot is on the stove 11. Based on the pot status information and the pot-free time information detected by the pot detection mechanism 20, the working state of the fire switch 30 is determined; the pot-free time information refers to the time when the pot has been removed from the stove 11, thus realizing intelligent control of the firepower of the stove 11.

[0056] In some embodiments, when the cookware detection mechanism 20 detects that no cookware is placed on the stove 11, the fire switch switches from a first opening state to a second opening state; the first opening state is the fire switch opening state corresponding to the firepower value of the stove when the cookware is removed, and the firepower value corresponding to the second opening state is less than the firepower value corresponding to the first opening state.

[0057] When the cookware detection mechanism 20 detects that the stove 11 is in a state where no cookware is placed and the duration of the absence of cookware is less than a first time threshold, the fire switch 30 switches from the second opening state to the first opening state.

[0058] When the cookware detection mechanism 20 detects that no cookware is placed on the stove 11 and the duration of the absence of cookware is not less than a first time threshold, the fire switch 30 switches from the second open state to the closed state.

[0059] Specifically, if the cookware detection mechanism 30 detects that the cookware has been removed while the cookware is cooking, it needs to record the current heat value or heat level of the stove 11 at the time the cookware was removed (i.e., the stove's heat switch opening state corresponding to the heat value at the time the cookware was removed is the first opening state). By reducing the current heat value or heat level through the heat switch 30, the current heat value can be adjusted to the lowest heat value or the current heat level can be adjusted to the lowest heat level (i.e., the heat switch switches from the first opening state to the second opening state). The heat value corresponding to the second opening state is lower than the heat value corresponding to the first opening state. The heat value corresponding to the second opening state can be the heat value corresponding to the lowest stove setting, or it can be the heat value corresponding to one or more lower heat levels than the heat level corresponding to when the cookware was removed. By switching the working state of the heat switch 30, gas consumption is reduced and gas utilization is improved. For example, when the pot is removed from the stove 11, the current heat value is 60%, which can be reduced to 50%, 40%, 30%, 10%, etc.

[0060] During the period when the cookware is removed, the cookware testing agency 20 still periodically checks whether the cookware is put back on the stove 11. Based on the cookware status information and the duration of time without cookware detected by the cookware testing agency 20, the firepower status of the stove 11 is adjusted in real time.

[0061] During cooking, the cookware may be removed from the stove 11. For example, after one dish is cooked and the next dish is prepared, the cookware needs to be removed from the stove 11 for cleaning. In this case, the cookware is only temporarily removed from the stove 11, typically for 0.5 to 1.5 minutes. While the cookware is off the stove 11, the stove 11 generally continues cooking at its original heat, resulting in wasted gas resources. Another example is when the cook finishes cooking a dish and plates it, then serves it directly to the table. In this situation, the cook may easily forget to turn off the stove 11, creating a safety hazard and wasting gas resources.

[0062] In this embodiment, during cooking, if the cookware detection mechanism 20 detects that the cookware has been removed (i.e., in a state where no cookware is placed), and the time the cookware has been removed (i.e., the duration without cookware) is less than a first time threshold, it indicates that the cookware has been placed back on the stove 11 within the first time threshold. In this case, during the period when the cookware is removed, the power switch 30 is controlled to reduce the current power value or the current power level, which can adjust the current power value to the lowest power value or the current power level to the lowest power level (i.e., the power switch 30 switches from the first opening state to the second opening state). When the cookware is placed back, the power switch 30 restores the reduced power value or power level to the power value or power level when the cookware was removed (i.e., the power switch 30 switches from the second opening state to the first opening state). Therefore, the stove fire control device provided in this application embodiment can reduce the fire value during the period when the pot is only temporarily removed from the stove 11, so as to reduce the waste of gas resources; when the pot is put back on the stove 11, the original fire value is used to continue cooking the food, so as to ensure the quality of the food.

[0063] If the cookware detection mechanism 20 detects that the cookware has been removed (i.e., in a state where no cookware is placed), and the time since removal (i.e., the duration without cookware) is not less than a first time threshold, then the fire switch 30 switches from the second open state to the closed state. The fire switch 30 controls the stove 11 to automatically cut off the gas and shut off the fire, thus addressing the safety hazard caused by the cook forgetting to turn off the stove and improving the safety of using the stove 11. The first time threshold can be 2 minutes, 3 minutes, etc.

[0064] In this example, based on the cookware status information and cookware-free time information detected by the cookware detection agency 20, as well as the current firepower value or current firepower level of the stove 11, the subsequent working state of the firepower switch 30 is adjusted to achieve automatic adjustment of the working state of the firepower switch 30.

[0065] In some embodiments, the stove fire control device further includes a controller 40, which is wired or wirelessly connected to the fire switch 30 and the cookware detection mechanism 20, respectively.

[0066] Specifically, the controller 40 is wired or wirelessly connected to the flame switch 30, such as a bidirectional electrical connection; the controller 40 is also wired or wirelessly connected to the cookware detection mechanism 20, such as a bidirectional electrical connection. The cookware status information detected by the cookware detection mechanism 20 is sent to the controller 40. In response to this information, the controller 40 controls the operating status of the stove 11 via the flame switch 30; and sends the current operating status of the stove 11 to the controller 40 via the flame switch 30. This allows the controller to adjust the operating status of the stove 11 in real time according to actual needs, meeting the requirements of automated cooking. Based on the cookware status information detected by the cookware detection mechanism 20, the controller can determine whether to ignite the stove 11, thus avoiding gas waste due to ignition when no cookware is placed, and preventing burns from flames, especially avoiding the risk of children accidentally operating the flame switch 30 and getting burned.

[0067] In this example, the cooperation of the fire switch 30, the controller 40 and the cookware detection mechanism 20 enables automated control of the firepower of the stove 11, eliminating the need for manual operation or reducing manual workload, and resulting in excellent food cooking performance. Furthermore, based on the triggering operation of the fire switch 30, the controller 40 controls the cookware detection mechanism 20 to start performing detection work, preventing the cookware detection mechanism 20 from being in a continuous working state, reducing power consumption, and extending the service life of the cookware detection mechanism 20.

[0068] In some implementations, reference Figure 1 The controller 40 is located within the control panel 50 and / or the mobile terminal.

[0069] Specifically, the control panel 50 is located on the cooktop body 10, and the controller 40 is located within the control panel 50, facilitating close-range adjustment of the cooktop 11's heat output. The control panel 50 features touch buttons for adjusting the cooktop 11's heat parameters via touch. The mobile terminal can be a mobile phone, laptop, tablet, or wearable device such as a watch. The controller 40 is located within the mobile terminal, enabling real-time display of the cooktop 11's operating status and remote control of the cooktop 11's operation. This enhances ease of operation and improves the user experience. In emergencies, the cooktop 11's heat output can be remotely shut off, improving the cooktop 11's safety.

[0070] In some implementations, reference Figure 2 The stove fire control device also includes a prompter 60, which is used to play prompt information through light signals and / or voice signals.

[0071] Specifically, the alert device 60 includes one or more of the following: a sound player, indicator lights, and a text display. The sound player can issue voice prompts, the specific content of which can be set according to the actual situation, such as "Please place the pot properly" or "Beware of fire." The indicator lights can display different colored light signals, such as red indicating that the pot is not properly placed, and green indicating safety. The text display can display different text as needed, such as "Please place the pot properly" or "Beware of fire."

[0072] For example, if the cookware detection mechanism 20 detects that no cookware is placed on the stove 11, the prompt 60 will emit a sound saying "Please place the cookware before igniting" to remind the operator to place the cookware in time to avoid flames from escaping and burning the operator. Alternatively, after the stove 11 is successfully ignited, the prompt 60 can emit a sound saying "Please set the cooking time" to remind the operator that the stove 11 has a timer function, and the operator can decide whether to activate the timer function according to their actual needs.

[0073] The indicator 60 can be installed in the control panel 50 and / or a mobile terminal. The control panel 50 is installed on the cooktop body 10, and the mobile terminal can be a mobile phone, laptop, tablet, or wearable device such as a watch. The indicator 60 is connected to the controller 40 via wired or wireless means, such as the signal output terminal of the controller 40 being electrically connected to the signal input terminal of the indicator 60. The controller 40 controls the indicator 60 to issue corresponding prompts based on the cookware status information detected by the cookware detection mechanism 20, and also controls the indicator 60 to issue corresponding prompts based on the working status of the fire switch 30, thus realizing the intelligent operation of the indicator 60.

[0074] In some implementations, reference Figure 2 The stove fire control device also includes a timer 70, which is used to time and / or schedule the working time of the stove 11, and to display the countdown time of the stove 11's operation.

[0075] Specifically, the timer 70 consists of a digital display tube and can be installed in the control panel 50 and / or a mobile terminal. It is used to time the operation of the stove 11, displaying the elapsed time, the countdown time, and also has a timer function. It allows setting a cooking time and automatically cooking according to the set time, reducing the workload of the cook and minimizing the risk of dry burning or fire caused by the stove 11 operating for extended periods when unattended. The timer 70 can be connected to the controller via wired or wireless means, such as a bidirectional electrical connection between the controller 40 and the timer 70.

[0076] For example, when the stove 11 is successfully ignited and the fire level is adjusted by the knob of the fire switch 30, the indicator 60 reminds the user that the timer function is available. If not needed, the timer function can be left unused. If needed, the working time of the stove 11 can be set through the control panel 50 of the stove 11 or through the mobile APP. After the working time of the stove 11 is set, the stove 11 enters the intelligent cooking mode. When the stove 11 has worked for the set time, the controller 40 controls the fire switch 30 to automatically cut off the gas supply and turn off the fire.

[0077] In some implementations, reference Figure 2 The stove 11 is equipped with a temperature sensor 80, which is used to acquire the temperature information of the cookware.

[0078] Specifically, the temperature sensor 80 is installed on the burner rack of the stove 11. Based on the temperature of the pot bottom fed back by the temperature sensor 80, the stove 11 adjusts its heat level or value, significantly reducing the risk of food burning, improving cooking quality, and enabling self-management of the cooking process. During cooking, the stove 11 operates at the set heat level and periodically uploads the current heat level, countdown time, and pot bottom temperature to a mobile app. After the set cooking time is reached, the stove 11 automatically shuts off the gas and turns off the flame, and notifies the mobile app that cooking is complete. The temperature sensor 80 is connected to the controller 40 via wired or wireless connection, such as an electrical connection between the signal output of the temperature sensor 80 and the signal input of the controller 40.

[0079] In some implementations, the operating state of the fire switch 30 is determined based on the cookware temperature information and overheating duration information obtained by the temperature sensor 80.

[0080] Specifically, based on the cookware temperature information and overheat duration information obtained by the temperature sensor 80, the working state of the fire switch 30 is determined. The temperature sensor 80 periodically detects the cookware temperature and sends the detected cookware temperature information and overheat duration information to the controller 40. The controller 40 controls the working state of the fire switch 30, such as controlling the on state, off state and different opening degree information of the fire switch 30, thereby controlling the firepower of the stove 11, reducing the workload of the cook, reducing cooking risks and improving cooking quality.

[0081] In some embodiments, when the temperature of the cookware detected by the temperature sensor 80 reaches a preset temperature threshold, the power switch 30 switches from a third opening state to a fourth opening state; wherein the power value corresponding to the fourth opening state is less than the power value corresponding to the third opening state.

[0082] When the overheating time of the cookware reaches the second time threshold corresponding to the fourth opening state of the fire switch 30, the fire switch switches from the fourth opening state to the off state.

[0083] Specifically, during cooking, the cooktop 11 periodically detects the temperature of the pot bottom through the temperature sensor 80. If the temperature detected by the temperature sensor 80 exceeds the preset temperature threshold (such as 150℃ or 200℃), the controller 40 controls the fire switch 30 to switch from the third opening state to the fourth opening state. That is, the cooktop 11 is controlled to reduce the current fire value or fire level (the corresponding fire switch is in the third opening state) until it is reduced to the minimum fire value or the lowest fire level (the corresponding fire switch is in the third opening state), thereby reducing gas consumption and preventing the pot from being continuously scorched at high temperatures.

[0084] If the pot's bottom temperature remains above the maximum heat setting for an extended period, reaching the second time threshold, the cooktop 11 determines the pot is dry-burning. The heat switch 30 switches from the fourth on / off state to the off state, forcibly shutting off the gas and turning off the heat. A notification is also sent to the mobile app indicating that cooking has stopped due to overheating. The second time threshold can be set according to actual needs, such as 5 minutes or 10 minutes.

[0085] It should be noted that the second opening state and the fourth opening state can be the same state or different opening states. Those skilled in the art can set them according to actual needs.

[0086] In a second aspect, this application provides a stove 11, which includes the stove fire control device described in any embodiment of this application.

[0087] According to the stove 11 provided by this utility model, the stove fire control device provided in any embodiment of this application can be used to determine whether to perform the stove 11 ignition operation by detecting the pot status information through the pot detection mechanism 20. This avoids the waste of gas resources caused by ignition when no pot is placed, and avoids the risk of burns to the operator caused by flames. In particular, it can avoid the risk of children being burned due to accidental operation of the fire switch 30, thus improving the safety of using the stove 11. It is understood that the specific technical effects of the stove 11 provided in the embodiments of this application are the same as those of the stove fire control device, and will not be described again in the embodiments of this application.

[0088] This invention aims to intelligently adjust the heat level of the stove 11 by combining information on whether a pot is placed on the stove 11 and the real-time temperature of the pot's bottom, and by controlling the heat switch 30. (Reference) Figure 3 The method of using the stove fire control device provided in this application embodiment includes:

[0089] When you start turning the fire switch 30 knob to ignite, if there is a pot on the stove 11, control the ignition needle 31 to ignite; otherwise, do not allow the ignition needle 31 to ignite.

[0090] After successful ignition, the cook adjusts the heat level and sets the working time of the stove 11 using the heat switch 30 knob. The stove 11 then operates at the set heat level, and the working time is recorded. When the set working time is reached, the stove 11 automatically cuts off the gas and turns off the flame.

[0091] If the stove timer function is not activated, the temperature sensor 80 periodically detects the pot temperature during cooking. If the temperature exceeds the limit, the heat is reduced by the power switch 30 until it reaches the lowest power level. If the pot temperature continues to exceed the limit even at the lowest power level, the stove 11 determines that the pot is dry-burning and forcibly shuts off the gas and turns off the stove.

[0092] It should be noted that the stove fire control device provided in this application embodiment can achieve its complete functions with the help of conventional computer programs for the program control part. For the functional units in the stove fire control device that require computer programs to operate successfully, their functions can be fully realized with the help of known computer processing methods.

[0093] The above description is merely a preferred embodiment of this application and an explanation of the technical principles employed. Those skilled in the art should understand that the scope of the utility model involved in this application is not limited to the technical solutions formed by specific combinations of the above-described technical features, but should also cover other technical solutions formed by arbitrary combinations of the above-described technical features or their equivalents without departing from the inventive concept. For example, technical solutions formed by substituting the above features with (but not limited to) technical features with similar functions disclosed in this application.
