Description

Technical Field

[0001] This invention relates to the field of kitchen appliances technology, and in particular to a stove and its control method. Background Technology

[0002] Gas stoves are essential kitchen cooking appliances for daily household use. A gas stove consists of a burner and a corresponding burner cap. There are two types of burner caps: a fixed design and a movable design.

[0003] In existing gas stoves, fixed burner caps, due to their fixed design, may increase maintenance difficulty and cost if cleaning or replacement of parts is required. Regarding safety, movable burner caps, if not properly secured or subjected to external force during combustion, may shift or detach, leading to unstable flames or flameout, and potentially causing fires. Currently, there is a lack of a solution that balances the safety of fixed designs with the flexibility of movable designs. Summary of the Invention

[0004] This invention provides a stove and its control method. Through a locking assembly between the upper, middle, and lower burner caps, the burner caps can be switched from a locked state to a disengaged state according to changes in the stove's usage status, facilitating cleaning for the user. Simultaneously, it can alert the user when the stove is not turned off, improving stove safety.

[0005] In a first aspect, embodiments of the present invention provide a stove, including a burner; the burner includes an outer ring flame cover; the outer ring flame cover includes an upper ring cover, a middle ring cover and a lower ring cover stacked from top to bottom;

[0006] The outer ring flame cap includes several locking components, which are spaced apart circumferentially along the outer ring flame cap.

[0007] The locking assembly has a locking state and a separating state; in the locking state, the upper ring cover, the middle ring cover, and the lower ring cover are locked together; in the separating state, the upper ring cover, the middle ring cover, and the lower ring cover can be separated from each other.

[0008] Optionally, the locking assembly includes a driving part, a fixing part, and a braking part; the braking part and the fixing part are two matching locking accessories; the driving part is electrically connected to the control part, and the driving part is configured to controllably drive the braking part to lock or disengage from the fixing part.

[0009] Optionally, the braking part is any one of a bolt, a female clip, or a pin, and the fixing part is any one of a nut, a male clip, or a pin hole that matches the braking part.

[0010] Optionally, at least one temperature sensor is provided on the wall surface of the outer ring flame cap, and the temperature sensor is configured to detect the wall surface temperature of the outer ring flame cap.

[0011] Optionally, the cooktop also includes an operation panel, which is electrically connected to the control unit and configured to generate cooktop on / off command signals in response to the user's operation of turning the cooktop on and off.

[0012] Secondly, embodiments of the present invention also provide a control method for a stove, applicable to any stove provided in embodiments of the present invention, the control method comprising:

[0013] Real-time acquisition of stove switch command signals;

[0014] Based on the stove switch command signal, the locking component is controlled in real time to be either locked or disengaged.

[0015] Optionally, based on the stove switch command signal, the locking assembly is controlled in real time to be in a locked state or a disengaged state, including: when the obtained stove switch command signal is a closed signal, the wall temperature of the outer ring burner is obtained; when the wall temperature of the outer ring burner is lower than a preset temperature threshold, the locking assembly is controlled to be in a disengaged state.

[0016] Optionally, after acquiring the stove switch command signal in real time, the method further includes: assigning a value of 1 when the stove switch command signal is an on signal and assigning a value of -1 when the stove switch command signal is an off signal; performing an accumulation operation on the detected stove switch command signals to obtain an accumulation value N, where 0 ≤ N ≤ 1; when N = 0, confirming that the stove is off and displaying the stove's off status; when N = 1, confirming that the stove is not off and providing a stove off prompt.

[0017] Optionally, when N=1, after confirming that the stove is not turned off and providing a stove-off prompt, the method further includes: when a stove-on / off command signal with a shutdown signal is received within a preset time, displaying the stove-off status; when no stove-on / off command signal with a shutdown signal is received within the preset time, controlling the burner to turn off and displaying the stove-off status.

[0018] Optionally, based on the stove switch command signal, the locking component is controlled in real time to be in a locked or open state, including: when the received stove switch command signal is an on signal, confirming the state of the locking component; when the locking component is in a locked state, displaying the locked state of the locking component; when the locking component is in an open state, controlling the locking component to be in a locked state and displaying the locked state of the locking component.

[0019] The technical solution of this invention includes a plurality of locking components in the outer ring burner cap of the stove, with the locking components spaced circumferentially along the outer ring burner cap. The locking components have a locked state and a separated state. In the locked state, the upper ring cap, middle ring cap, and lower ring cap are locked together. In the separated state, the upper ring cap, middle ring cap, and lower ring cap can be separated from each other. This invention optimizes the design defects of gas stove burner caps. Traditional movable burner caps are prone to detachment due to external force, affecting flame stability and even causing flameout, endangering safety. While fixed burner caps are stable, they are difficult to maintain and costly, affecting convenience and user experience. To completely overcome the above problems, this invention introduces a locking component based on the original burner cap structure. The locking component adjusts its state according to the gas stove's on / off command signal. When the stove is working, it automatically locks the burner cap to ensure its structural stability, effectively preventing positional displacement or even detachment caused by external forces, thus improving the safety of the equipment. When the stove is not in operation, the locking component switches to the unlocked state, allowing users to easily disassemble the burner cap for necessary cleaning and component replacement, simplifying the maintenance process, reducing maintenance costs, and improving the user experience.

[0045] Figure 1 This is a schematic diagram of the structure of a stove provided in an embodiment of the present invention. Figure 2 This is an exploded view of a stove provided in an embodiment of the present invention. Figure 3 This is a longitudinal sectional view of a stove provided in an embodiment of the present invention. Figure 4 Provided by the embodiments of the present invention Figure 3 Enlarged view of point A in the image. Figure 5 This is a schematic diagram of the locking assembly of the stove provided in an embodiment of the present invention in the locked state. Figure 6 yes Figure 5 Enlarged view within the dashed box shown. Figure 7 This is a schematic diagram of the locking assembly of the stove provided in an embodiment of the present invention in a disassembled state. Figure 8 yes Figure 7 The enlarged view within the dashed box shown is first referenced. Figures 1-4The stove includes a burner head 30, a gas distribution seat 40, and an outer ring burner cap 10. The outer ring burner cap 10 includes an upper ring cap 11, a middle ring cap 12, and a lower ring cap 13 stacked from top to bottom. A main flame ring seam 14 is formed between the outer circumference of the upper ring cap 11 and the inner circumference of the middle ring cap 12, and a flame stabilizing ring seam 15 is formed between the outer circumference of the middle ring cap 12 and the inner circumference of the lower ring cap 13. A connecting cavity 18 is formed between the lower end of the outer circumference of the upper ring cap 11 and the lower end of the inner circumference of the lower ring cap 13, and both the main flame ring seam 14 and the flame stabilizing ring seam 15 are connected to the connecting cavity 18.

[0046] Gas distribution seat 40 is installed on the burner head 30, outer ring flame cover 10 is installed on the gas distribution seat 40, an outer ring mixing channel 31 is provided inside the burner head 30, a gas distribution channel 41 is provided on the gas distribution seat 40, the outer ring mixing channel 31 is connected to the gas distribution channel 41, the main flame ring seam 14 and the flame stabilizing ring seam 15 are both connected to the gas distribution channel 41.

[0047] The upper side of the burner head 30 is provided with a number of outer ring air outlets 311 arranged in a circumferential direction, and the gas distribution seat 40 is provided with a corresponding number of air inlets 42, with each air inlet 42 being positioned above an outer ring air outlet 311.

[0048] Continue to refer to Figures 5-8 In this embodiment of the invention, the outer ring burner cap 10 includes a plurality of locking components 16, which are spaced apart circumferentially along the outer ring burner cap 10 and divide the main burner ring seam 14 and the flame stabilizing ring seam 15 into at least two corresponding segments. The locking components 16 have a locking state and a split state. In the locking state, the upper ring cap 11, the middle ring cap 12, and the lower ring cap 13 are locked together. In the split state, the upper ring cap 11, the middle ring cap 12, and the lower ring cap 13 can be separated from each other. The stove also includes a control unit 50, which is electrically connected to the locking components 16. The control unit 50 is configured to acquire the stove switch command signal in real time and control the locking components 16 to be in the locking state or the split state in real time according to the stove switch command signal.

[0049] The burner 100 also includes an inner ring burner cap 20. In addition to the outer ring mixing channel 31, the gas distribution seat 40 also has an inner ring mixing channel 32. The inlet of the outer ring mixing channel 31 is used to connect with the outer ring nozzle, and the outer ring outlet 311 of the outer ring mixing channel 31 extends to the upper side of the burner head 30. The inlet of the inner ring mixing channel 32 is used to connect with the inner ring nozzle, and the inner ring outlet of the inner ring mixing channel 32 also extends to the upper side of the burner head 30. The gas distribution channel 41 in the gas distribution seat 40 has an inlet hole 42. The gas distribution seat 40 covers the burner head 30 so that the inlet hole 42 is opposite to the outer ring outlet 311, thereby connecting the outer ring mixing channel 31 with the gas distribution channel 41. The outer ring burner cap 10 is annular and has a communicating cavity 18. The outer ring burner cap 10 also has a main flame ring seam 14 and a flame stabilizing ring seam 15, which are coaxially arranged and both communicate with the communicating cavity 18. The outer ring burner cap 10 covers the gas distribution seat 40, thereby connecting the communicating cavity 18 with the gas distribution channel 41. In other words, the outer ring mixing channel 31, the gas distribution channel 41, and the communicating cavity 18 are sequentially connected. The inner ring burner cap 20 covers the burner head 30, and the multiple inner ring flame holes 21 on the inner ring burner cap 20 are all connected with the inner ring gas outlet.

[0050] like Figure 3 As shown, the working principle of the burner 100 is as follows: the outer ring nozzle injects gas into the outer ring mixing channel 31. During this process, primary air is injected into the outer ring mixing channel 31. The primary air and gas mix in the outer ring mixing channel 31 and then enter the gas distribution channel 41. The mixed gas flows and mixes in the gas distribution channel 41 and then enters the connecting cavity 18. Finally, it is discharged from the main flame ring slit 14 and the flame stabilizing ring slit 15 and burned. At the same time, the inner ring nozzle injects gas into the inner ring mixing channel 32. During this process, primary air is injected into the outer ring mixing channel 31. The primary air and gas mix in the inner ring mixing channel 32 and then enter the inner ring burner cap 20. Finally, it is discharged from each inner ring burner hole 21 and burned.

[0051] like Figure 4 As shown, the outer ring flame cap 10 specifically includes an upper ring cap 11, a middle ring cap 12, and a lower ring cap 13. The upper side of the outer ring flame cap 10 has a conical surface 17. Along the direction from bottom to top, the cross-section of the conical surface 17 gradually decreases. The flame stabilizing ring slit 15 is arranged around the outer periphery of the main flame ring slit 14, and the outlets of the flame stabilizing ring slit 15 and the main flame ring slit 14 both extend to the conical surface 17. A spacer 121 is provided between the main flame ring slit 14 and the flame stabilizing ring slit 15. Along the arrangement direction of the outlets of the main flame ring slit 14 and the flame stabilizing ring slit 15 (that is, the slit width direction of the main flame ring slit 14 and the slit width direction of the flame stabilizing ring slit 15), the width of the spacer 121 is D3, and the ratio of D3 to D2 is 0.8-1.2.

[0052] It should be noted that the extension direction of the main fire ring slit 14 and the tilting direction of the flame stabilizing ring slit 15 can have a certain angle, which is not specifically limited here.

[0053] like Figures 5-8 As shown, the locking assembly 16 may specifically include a drive unit 161, a fixing unit 162, and a braking unit 163; the drive unit 161 and the braking unit 163 are connected in a transmission manner, and the fixing unit 162 and the braking unit 163 are two mutually matching locking accessories; the drive unit 161 is electrically connected to the control unit 50, and the drive unit 161 is configured to controllably drive the braking unit 163 to lock or disengage with the fixing unit 162. The braking unit 163 is any one of a bolt, a snap-fit ​​female, or a pin, and the fixing unit 162 is any one of a nut, a snap-fit ​​male, or a pin hole that matches the braking unit 163. The outer ring burner cap 10 has at least one temperature sensor 19 on its wall surface, and the temperature sensor 19 is configured to detect the wall surface temperature of the outer ring burner cap 10. The stove also includes an operation panel 52, which is electrically connected to the control unit 50 and is configured to generate a stove switch command signal in response to the user's stove switch operation. The cooktop also includes a display screen 51, which is electrically connected to the control unit 50 and is configured to controllably display the working status of the cooktop.

[0054] When the fixing part 162 and the braking part 163 of the locking assembly 16 are locked together, the locking assembly 16 of the stove is in a locked state. When the fixing part 162 of the locking assembly 16 is removed from the braking part 163, the locking assembly 16 of the stove is in a disassembled state.

[0055] The above technical solution involves setting several locking components in the outer ring burner cap of the stove. These locking components are spaced apart circumferentially along the outer ring burner cap, dividing the main burner ring seam and the flame stabilizing ring seam into at least two corresponding segments. The locking components have a locking state and a separating state. In the locking state, the upper ring cap, middle ring cap, and lower ring cap are locked together. In the separating state, the upper ring cap, middle ring cap, and lower ring cap can be separated from each other. The stove also includes a control unit connected to the locking components. The control unit is configured to acquire stove switch command signals in real time and control the locking components to be in the locking state or the separating state in real time according to the stove switch command signals. This invention solves the problems of traditional movable burner caps being prone to displacement and detachment due to external forces, affecting flame stability, or even causing flameout and endangering safety; and fixed burner caps, while stable, are difficult and costly to maintain. While retaining the original burner cap structure, a locking component is introduced. This component adjusts its state according to the gas stove's on / off command signal. When the stove is in operation, the burner cap is automatically locked to ensure structural stability and improve the safety of the equipment. When the stove is not in operation, the locking component switches to the unlocked state, allowing users to easily disassemble the burner cap for necessary cleaning and parts replacement, simplifying the maintenance process, reducing maintenance costs, and improving the user experience.

[0056] Based on the stove described in the above embodiments, this invention also provides a method for controlling the stove. Figure 9 This is a flowchart illustrating a stove control method according to an embodiment of the present invention. (Refer to...) Figure 9 The adjustment method includes:

[0057] S110: Real-time acquisition of stove switch command signals.

[0058] The on / off command signal of the stove can be understood as a signal generated by the user through operating the control panel or automatically triggered by other sensors (such as flame sensors) indicating that the stove has entered the working state.

[0059] Specifically, when the stove is turned on, the control unit quickly receives the stove-on signal; when the stove is turned off, the control unit immediately receives the stove-off signal.

[0060] S120. Based on the stove switch command signal, control the locking component to be in a locked or unlocked state in real time.

[0061] Specifically, when the control unit 50 receives a stove-on signal, the control unit 50 determines that the stove is in working condition. At this time, in order to prevent the burner cap from shifting and falling off due to external force, the control unit 50 controls the locking assembly 16 to lock the burner cap. When the stove is off, the control unit 50 receives a stove-off signal and determines that the stove is in non-working condition. At this time, the control unit 50 controls the locking assembly 16 to switch to the unlocked state, which is convenient for users to perform subsequent cleaning, maintenance or component replacement operations.

[0062] The above technical solution first acquires the stove's on / off command signal, and then controls the locking component to be in a locked or unlocked state in real time according to the on / off command signal. Based on the existing burner cap structure, the locking component automatically adjusts its state according to the on / off command signal. When the stove is working, it automatically locks the burner cap, ensuring its structural stability and effectively preventing positional displacement or even detachment caused by external forces, thus improving the safety of equipment use. When the stove is not in operation, the locking component switches to the unlocked state, allowing users to easily disassemble the burner cap for necessary cleaning and component replacement, simplifying the maintenance process, reducing maintenance costs, and improving the user experience. This invention improves the stability of the stove in the working state and its convenience in the non-working state, effectively preventing the burner cap from falling off in the working state, ensuring the safety of equipment operation, while also addressing the disassembly needs in the non-working state, thus improving the user experience.

[0063] Figure 10 This is a schematic flowchart of another stove control method provided in an embodiment of the present invention, for reference. Figure 10The stove and control method based on the above embodiments have been refined or optimized. Specifically, according to the stove switch command signal, the locking component is controlled in real time to be in a locked state or a disengaged state, including: when the obtained stove switch command signal is a closed signal, the wall temperature of the outer ring burner is obtained; when the wall temperature of the outer ring burner is lower than a preset temperature threshold, the locking component is controlled to be in a disengaged state.

[0064] For details not covered in this embodiment, please refer to the previous embodiment.

[0065] like Figure 10 As shown in the figure, another method for controlling a stove provided by an embodiment of the present invention includes the following steps:

[0066] S210: Real-time acquisition of stove switch command signals.

[0067] S220. When the obtained stove switch command signal is a closed signal, obtain the wall temperature of the outer ring burner.

[0068] The wall temperature of the outer ring burner cap 10 can be understood as the wall temperature of the outer ring burner cap 10 detected by the temperature sensor 19 installed on the wall of the outer ring burner cap 10.

[0069] Specifically, when the control unit 50 receives a signal from the user to turn off the stove, the temperature sensor 19 begins to detect the wall temperature T.

[0070] S230. When the wall temperature of the outer ring fire cover is lower than the preset temperature threshold, the locking assembly is controlled to be in a separate state.

[0071] The temperature threshold can be understood as a preset temperature suitable for disassembling the flame cap.

[0072] Specifically, when the control unit 50 detects that the wall temperature T of the outer ring flame cap 10 is lower than the preset temperature threshold (e.g., T≤303K), the control unit 50 sends a separation command to the drive unit 161, and the drive unit 161 controls the braking unit 163 to move to the open state.

[0073] This invention refines the specific circumstances under which the locking assembly is in a separate state, based on the above embodiments. By introducing the wall temperature of the outer ring burner cap as a monitoring variable, the temperature sensor begins to detect the wall temperature when the stove is turned off. This ensures that the outer ring burner cap is switched to the separate state only after the stove has been used and the burner temperature has dropped sufficiently, facilitating user cleaning while preventing burns, improving safety, reducing the working time of the temperature sensor, and extending the service life of the components.

[0074] Figure 11 This is a schematic flowchart of another stove control method provided in an embodiment of the present invention, for reference. Figure 11The stove and control method based on the above embodiments have been refined or optimized. Specifically, after acquiring the stove switch command signal in real time, the method further includes: assigning a value of 1 when the stove switch command signal is an on signal, and assigning a value of -1 when the stove switch command signal is an off signal; sequentially accumulating the detected stove switch command signals to obtain an accumulated value N, where 0 ≤ N ≤ 1; when N = 0, confirming that the stove is off and displaying the stove's off status; when N = 1, confirming that the stove is not off and providing a stove off prompt.

[0075] Furthermore, when N=1, after confirming that the stove is not turned off and providing a stove-off prompt, the system further includes: displaying the stove's off status when a stove-on / off command signal is received within a preset time; and controlling the burner to turn off and displaying the stove's off status when no stove-on / off command signal is received within the preset time.

[0076] For details not covered in this embodiment, please refer to the previous embodiment.

[0077] like Figure 11 As shown in the figure, another method for controlling a stove provided by an embodiment of the present invention includes the following steps:

[0078] S310: Real-time acquisition of stove switch command signals.

[0079] S320: Based on the stove switch command signal, control the locking component to be in a locked or unlocked state in real time.

[0080] S330. When the stove switch command signal is an on signal, assign a value of 1; when the stove switch command signal is a off signal, assign a value of -1. Perform cumulative calculation on the detected stove switch command signals to obtain the cumulative value N, where 0≤N≤1.

[0081] Specifically, the accumulated value N is calculated based on the received stove switch command signals. Whenever an on signal is received, the current accumulated value N is increased by 1; whenever an off signal is received, the current accumulated value N is decreased by 1.

[0082] S340. When N=0, confirm that the stove is off and display the stove's off status.

[0083] The off status display is implemented by the display screen 51. For example, it can be a clear "OFF" sign, an off indicator light, or an icon indicating that it is off.

[0084] Specifically, when N=0, it indicates that in the most recent operation sequence, the stove's on and off signals completely cancel each other out. This means that since the last successful shutdown of the stove, no new on signal has been received, or all received on signals have been canceled out by the corresponding off signals (e.g., the user failed to ignite the stove after multiple attempts and eventually gave up). In this case, it can be confirmed that the stove is currently off, and the control unit 50 will issue a shutdown prompt to clearly convey to the user that the stove has been safely shut off.

[0085] S350. When N=1, confirm that the stove is not turned off and prompt the user to turn off the stove.

[0086] Specifically, when N=1, it indicates that the stove was turned on in the most recent operation sequence, and no shutdown signal was subsequently received to cancel this on signal. This means that the stove is still in operation or the user forgot to turn it off. At this time, the control unit 50 controls the display screen 51 to display "Stove not turned off," waiting for user confirmation.

[0087] S360. When a stove switch command signal with a shutdown signal is received within a preset time, the stove's shutdown status is displayed.

[0088] The preset time can be understood as the time during which the control unit 50 controls the display screen 51 to show "the stove is not turned off" and waits for user confirmation.

[0089] Specifically, if the user inputs a confirmation signal through the operation panel 52, the control unit 50 controls the stove to turn off, and the display screen 51 displays "Stove off".

[0090] S370. If no stove switch command signal with a shutdown signal is received within a preset time, the burner is controlled to shut off, and the stove shutdown status is displayed.

[0091] Specifically, if the user does not confirm within a preset time (e.g., 10-60 seconds, preferably 30 seconds), the control unit 50 will automatically turn off the stove, and the display screen 51 will show "Stove off".

[0092] The stove control method provided in this invention first acquires the stove switch command signal in real time and controls the locking component state in real time according to the switch command signal; then, it accurately determines the current state of the stove by accumulating the switch command signal; further, when the stove is detected to be not turned off, it promptly reminds the user to avoid energy waste and safety hazards; finally, it gives the user a certain amount of time to confirm and respond to avoid accidental shutdown due to misoperation. If the user does not confirm within a preset time, the burner is automatically turned off and the off status is displayed to avoid fire and other safety hazards. Based on the control methods of the above embodiments, this invention adds a mechanism combining accumulation calculation and preset time judgment, effectively avoiding energy waste and safety hazards caused by user misoperation or forgetfulness, and can also automatically take safety measures when necessary to protect the user's life and property.

[0093] Figure 12 This is a schematic flowchart of another stove control method provided in an embodiment of the present invention, for reference. Figure 12 The stove and control method based on the above embodiments have been refined or optimized. Specifically, according to the stove switch command signal, the locking component is controlled in real time to be in a locked or open state, including: when the obtained stove switch command signal is an open signal, confirming the state of the locking component; when the locking component is in a locked state, displaying the locked state of the locking component; when the locking component is in an open state, controlling the locking component to be in a locked state, and displaying the locked state of the locking component.

[0094] For details not covered in this embodiment, please refer to the previous embodiment.

[0095] like Figure 12 As shown in the figure, another method for controlling a stove provided by an embodiment of the present invention includes the following steps:

[0096] S410: Real-time acquisition of stove switch command signals.

[0097] S420. When the received stove switch command signal is an open signal, confirm the status of the locking component.

[0098] In this context, confirming the state of the locking component 16 can be understood as comparing whether the state of the locking component corresponds to the current switching command.

[0099] Specifically, when the control unit 50 detects a stove-start signal from the user, it does not immediately initiate the combustion process. Instead, it first performs a safety check—confirming the current state of the locking assembly 16. This is to ensure that all critical components are securely locked before the stove is ignited, preventing loosening or detachment during combustion, thereby improving the safety of stove use.

[0100] S430. When the locking assembly is in the locked state, display the locking status of the locking assembly.

[0101] Specifically, when the control unit 50 confirms that the locking component 16 is in the locked state and the stove can be used safely, the control unit 50 will clearly show the user the locking status of the locking component 16.

[0102] S440. When the locking assembly is in a separate state, control the locking assembly to be in a locked state and display the locked state of the locking assembly.

[0103] Specifically, if the control unit 50 detects that the locking assembly 16 is currently in a separated state, the control unit 50 will immediately control the system to activate the locking mechanism, changing the locking assembly 16 from a separated state to a locked state. During the locking process, the control unit 50 will display the progress of the locking process and the status after the locking is completed to the user.

[0104] The control method for a stove provided in this embodiment of the invention, based on the control methods of the aforementioned embodiments, specifically describes a control method for the pre-start self-check process. First, when the control unit receives a stove start signal, it confirms the current state of the locking assembly to prevent the stove from starting the combustion process while the assembly is in a separate state. Subsequently, after confirming that the locking assembly is in the locked state, the control unit clearly displays this state to the user, allowing the user to intuitively understand the current state of the stove and ensuring that the stove operates in a safe condition. Simultaneously, if the system detects that the locking assembly is currently in a separate state, the control unit quickly activates the locking mechanism, changing the locking assembly from a separate state to a locked state. During this process, the system also uses a feedback mechanism to display the progress of the locking process and the state after locking is completed, ensuring the user has a clear understanding of the entire process. Through the above control method, this embodiment of the invention, while inheriting the advantages of the aforementioned embodiments, further enhances the safety of stove use, bringing users a more convenient and reassuring experience.

[0105] Figure 13 This is a schematic flowchart of another burner control method provided in an embodiment of the present invention, for reference. Figure 13 The present invention optimizes the above solution, and the control method includes the following specific steps:

[0106] S510, Stove is turned on.

[0107] After this step is completed, proceed with S520.

[0108] S520, the control unit records the stove's start signal as "+1".

[0109] After this step is completed, proceed with S521.

[0110] S521. Determine whether the braking unit is in the closed state.

[0111] If yes, execute S522; otherwise, execute S523.

[0112] S522, Ignite the stove. The display shows "lock status".

[0113] S523, the drive unit moves the brake unit to the closed state, and the stove is ignited. The display screen shows "locking status".

[0114] After this step is completed, proceed with S530.

[0115] S530, Stove off.

[0116] After this step is completed, proceed with S540.

[0117] S540: The temperature sensor detects the wall temperature, and the control unit records the stove's shutdown signal as "-1" and performs calculations.

[0118] After this step is completed, S550 and S560 will be executed.

[0119] S550, Determine if T ≤ 303K.

[0120] If yes, execute S551; otherwise, execute S540.

[0121] S551, the drive unit moves the brake unit to the open state; the display screen shows "part status".

[0122] S560. Determine whether the result of the operation is ≤0.

[0123] If yes, execute S561; otherwise, execute S562.

[0124] S561, The display screen shows "The stove is not turned off".

[0125] After this step is completed, proceed with S570.

[0126] S562, The display screen shows "Stove off".

[0127] S570. Determine whether the user will confirm within the pending confirmation time.

[0128] The waiting time can be understood as the preset response time. For example, the waiting time can be preset to 10-60 seconds, preferably 30 seconds.

[0129] If yes, execute S580; otherwise, execute S561.

[0130] S580, the control unit automatically shuts off the stove.

[0131] After this step is completed, proceed to step S562.

[0132] The stove control method provided in this invention first ensures safety by determining whether the braking mechanism is in the closed state before ignition, thus improving safety. Then, after the stove is turned off, a temperature sensor detects the wall temperature to determine if the stove's locking mechanism is adjustable for unlocking. Finally, a user confirmation mechanism is introduced; if the stove is not confirmed to be off within a specific time, the system automatically shuts it off, preventing safety hazards caused by user negligence. This invention, through the above control method, achieves safe and efficient management of the stove's locking components, improving user experience and safety.
