[0038] This invention proposes a method for detecting and controlling the battery of a gas stove.

[0039] Reference Figure 1 In one embodiment of the present invention, the gas stove battery detection and control method includes:

[0040] Step S100: Obtain the battery voltage value before the gas stove is ignited, and the battery voltage value when the gas stove is ignited.

[0041] Understandably, a smart gas stove includes an electronic control board, a main controller, and various detection sensors. The electronic control board can also house voice prompt circuits, wireless circuits, temperature sensors, gas detection sensors, and LED indicator circuits to achieve intelligent control of the gas stove. A battery is typically also included in a smart gas stove. The battery is electrically connected to the electronic control board and supplies power to the aforementioned circuit modules when the gas stove is operating, thus enabling intelligent control. The battery can be alkaline or carbon-based and is located within the gas stove, specifically within the knob body. The battery can be detachably installed in a pre-set space within the knob body, or it can be integrated into the knob body as a single unit. The battery provides power to the various functional modules on the gas stove's electronic control board. This battery can be a primary battery such as a dry cell battery, or it can be a rechargeable battery capable of being recharged twice. Specifically, the battery can be a nickel-metal hydride (NiMH) battery, a lithium-ion (Li-ion) battery, or other rechargeable batteries.

[0042] Gas stoves are also equipped with microswitches, thermocouples, and other components. An ignition detection circuit can also be installed on the control board. The microswitch is configured to correspond to the position of the gas stove's ignition switch (gas rotary valve) and closes / opens based on the triggering of the gas rotary valve. For example, when the gas rotary valve is rotated to a preset position to open and ignite, the microswitch is triggered and closes. When the gas rotary valve is rotated back to the zero-degree rotation angle position to close, the microswitch is triggered and opens.

[0043] The thermocouple includes a thermocouple probe located at the burner head and a thermocouple detection circuit integrated into the pulse igniter. Similarly, an electromotive force (EMF) signal is obtained in real time, and the burner head temperature is sensed and an EMF signal is emitted by the thermocouple detection circuit. The thermocouple can also be used in conjunction with a valve stem rotation angle detector to detect accidental flameout. The valve stem rotation angle detector detects the rotation angle position of the gas rotary valve stem and emits a rotation angle position signal. When the rotation angle position signal is non-zero degrees, it indicates that the gas rotary valve is open. When the EMF signal drops from a high level (greater than a predetermined threshold, e.g., 2mV) to a low level (below a predetermined threshold), it indicates that the burner head has shut off, thus confirming an accidental flameout of the gas stove.

[0044] The ignition detection circuit can determine the start of burner ignition by detecting the closure of a microswitch or by detecting a jump in the electromotive force of a thermocouple from a low level below a predetermined lower threshold to a high level above an upper predetermined threshold. The ignition detection circuit can also detect the operating status of the microswitch and thermocouple to determine the operating status of the gas stove; for example, detecting the microswitch can determine whether the gas stove has been triggered for ignition or is in an ignition state.

[0045] In some embodiments, the gas stove is equipped with a power-start control circuit. This circuit receives an ignition trigger signal from the gas stove and operates when it receives the signal; otherwise, it remains inactive. In other words, the power-start control circuit can detect the gas stove's operating status when it starts working. For example, it can determine whether the gas stove has started working by detecting the rotation angle of the ignition switch (gas rotary valve). When it is determined that the gas stove has started working, the power-start control circuit outputs an enable control signal to the power conversion circuit, thereby controlling the power conversion circuit to operate and convert the battery's electrical energy for power supply to the main controller, voice reminder circuit, wireless circuit, temperature detection sensor, gas detection sensor, and LED indicator circuit, thus achieving intelligent control of the gas stove. When the gas stove is not in operation, the power start control circuit will not output an enable control signal to the power conversion circuit. The power conversion circuit will not operate, and its output will not provide converted electrical energy. At this time, the main controller, voice reminder circuit, wireless circuit, temperature sensor, gas sensor, and LED indicator circuit will operate without power. Therefore, the power conversion circuit can be controlled to operate based on whether the gas stove is in operation. This ensures that when the gas stove is not in operation, the power conversion circuit will not supply power to the main controller, voice reminder circuit, wireless circuit, temperature sensor, gas sensor, and LED indicator circuit, reducing standby power consumption.

[0046] The gas stove is equipped with a gas pulse igniter, which includes a solenoid valve control circuit and a pulse ignition generator. A microswitch is configured to correspond to the position of the gas stove's ignition switch (gas rotary valve) and closes / opens based on the rotation of the gas rotary valve. For example, when the gas rotary valve is rotated to a preset position to open for ignition, the microswitch is triggered and closes. When the gas rotary valve is rotated back to a zero-degree rotation angle position to close, the microswitch is triggered and opens. The opening / closing of the microswitch controls the operation of the pulse ignition generator and the solenoid valve control circuit. When the microswitch controls the pulse ignition generator and the solenoid valve control circuit, the current to the solenoid valve coil is controlled by the solenoid valve control circuit to open or close the solenoid valve. When the solenoid valve is open, the combustion path is open, and simultaneously, the pulse ignition generator controls the ignition needle to produce a high-voltage spark, completing ignition and starting the gas stove. This process is the gas stove's ignition process.

[0047] In this embodiment, the power start-up control circuit can control the power conversion circuit to operate, supplying power to the electronic control board to determine when the gas stove is triggered. The battery voltage is then detected, and the voltage at which the gas stove is triggered is used as the voltage before ignition. Alternatively, the battery voltage can be detected after the microswitch has been closed for a certain period, or when the gas stove is determined to be in ignition state based on the electromotive force generated by the thermocouple, and the voltage at which the gas stove is in ignition state is used as the voltage at which the gas stove is ignited.

[0048] Step S200: Determine the current gas stove battery type based on the battery voltage value obtained before the gas stove is ignited and the battery voltage value obtained when the gas stove is ignited.

[0049] Understandably, the solenoid valve of a gas stove is one of the most power-consuming loads in the gas stove. During ignition and shutdown, the gas stove consumes a significant amount of battery energy. Furthermore, different types of batteries used in gas stoves result in different voltage drops when the flame is turned off, and similarly, different instantaneous voltage drops during ignition. For example, with the same battery voltage, the instantaneous voltage drop when the gas stove valve is closed (battery voltage before valve closure minus battery voltage at valve closure) is typically 0.2V for an alkaline battery and 0.5V for a carbon-based battery. Similarly, the instantaneous voltage drop when the gas stove valve is closed is typically 0.2V for an alkaline battery and 0.5V for a carbon-based battery. Based on the above principle, this embodiment can determine the type of gas stove battery by obtaining the battery voltage value before the gas stove is ignited and the battery voltage value when the gas stove is ignited, that is, by the voltage drop of the battery before and after the gas stove is ignited.

[0050] Step S300: Upon receiving the automatic valve shut-off function setting instruction, determine whether the gas stove battery meets the automatic valve shut-off setting conditions based on the gas stove battery type and battery voltage value. If it does, set the gas stove to automatically shut off the valve.

[0051] It should be noted that the main controller in a gas stove, such as a microcontroller, typically operates at 2V. If the battery voltage drops below the main controller's operating voltage when the gas stove is turned off or ignited, the microcontroller system may reset due to the low voltage, failing to properly execute the valve-closing action. This will result in the gas stove being unable to properly shut off the flame, thus failing to respond to the user-set automatic shut-off function. In severe cases, this could even pose a fire or dry-burning risk, or cause battery depletion, affecting normal use of the gas stove. The automatic valve shut-off function setting command can be any one or a combination of timed valve opening / closing function setting commands, countdown valve shut-off function setting commands, anti-dry-burning function setting commands, smart recipe setting commands, and remote shut-off control setting commands. For example, when setting the timed opening / closing function, the user can use a mobile terminal (phone, smart bracelet, smartwatch, tablet) to set the gas stove's on / off time, as well as the set duration. The user then sends the corresponding control command to the gas stove via the mobile terminal, selects the timer using the operation buttons on the mobile terminal, plays the standard operating procedure, and completes the cooking operation according to the prompts. Upon receiving the automatic valve shut-off function setting command, the system needs to determine the voltage drop corresponding to the gas stove's battery type when the stove is turned off. If the battery voltage drop does not cause the microcontroller to reset when the gas stove is turned off, then the current battery voltage value meets the automatic valve shut-off setting conditions. When the automatic valve shut-off setting conditions are met, the main controller and other circuit modules in the gas stove configure corresponding parameters according to the automatic valve shut-off function setting command, such as the gas stove's start-up time, end-of-operation time, and the duration of different flame levels at each stage, to respond to the user-set automatic shut-off function and achieve intelligent control of the gas stove.

[0052] This invention provides a gas stove control method that acquires the battery voltage value before and during gas stove ignition. Based on these values, it determines the current gas stove battery type. Upon receiving an automatic valve shut-off function setting command, it determines whether the gas stove battery meets the automatic valve shut-off setting conditions based on the battery type and voltage value. If the conditions are met, the automatic valve shut-off function is set. This invention ensures sufficient battery power for the corresponding type before the user needs to activate the touchscreen display to set automatic shut-off functions such as timed shut-off, anti-dry-burning shut-off, and remote shut-off, as well as other intelligent functions like smart recipes. This allows the intelligent functions of the gas stove to operate normally, thereby improving the safety and reliability of the gas stove.

[0053] Reference Figure 2In one embodiment, step S200, the step of determining the current gas stove battery type based on the obtained battery voltage value before the gas stove is ignited and the battery voltage value at the time of gas stove ignition, specifically includes:

[0054] Step S210: Determine the voltage drop of the gas stove under load based on the battery voltage value before the gas stove is ignited and the battery voltage value when the gas stove is ignited.

[0055] In this embodiment, the voltage drop of the gas stove under load can be determined by calculating the battery voltage value before the gas stove is ignited and the battery voltage value when the gas stove is ignited, and obtaining the voltage difference of the gas stove battery before and after the load. The voltage difference of the gas stove battery before and after the load is the voltage drop of the gas stove under load.

[0056] Step S220: Determine the current gas stove battery type based on the voltage drop of the gas stove under load and the preset voltage difference.

[0057] In this embodiment, under the same battery voltage, the instantaneous voltage drop of an alkaline battery when the gas stove valve is closed (battery voltage before valve closure minus battery voltage at valve closure) is generally 0.2V, while that of a carbon-based battery is generally 0.5V. Similarly, the instantaneous voltage drop of an alkaline battery when the gas stove valve is closed (battery voltage before ignition valve minus battery voltage at ignition valve) is generally 0.2V, while that of a carbon-based battery is generally 0.5V. Based on the above principle, this embodiment can determine the gas stove battery type by obtaining the battery voltage value before and at gas stove ignition, i.e., by comparing the voltage drop before and after gas stove ignition (i.e., when the gas stove is under load) with a preset voltage difference. Figure 3 As shown, the specific steps to determine the type of gas stove battery based on the comparison results are as follows:

[0058] Step S221: When the voltage drop of the gas stove under load is less than or equal to the preset voltage difference, the current gas stove battery type is determined to be an alkaline battery.

[0059] Step S222: When the voltage drop of the gas stove under load is greater than the preset voltage difference, the current gas stove battery type is determined to be a carbon-zinc battery. The preset voltage difference can be any value between the instantaneous voltage drop of an alkaline battery when the gas stove is in the suction valve and the instantaneous voltage drop of a carbon-zinc battery when the gas stove is closed. For example, if the instantaneous voltage drop of an alkaline battery when the gas stove is in the suction valve is 0.2V and the instantaneous voltage drop of a carbon-zinc battery when the gas stove is closed is 0.5V, the preset voltage difference can be set to 0.35V.

[0060] Reference Figure 4 In one embodiment, the step of determining whether the gas stove battery meets the automatic valve shut-off setting conditions based on the gas stove battery type and battery voltage value when receiving the automatic valve shut-off function setting command, and setting the gas stove to automatically shut off the valve when the conditions are met, specifically includes:

[0061] Step S310: Calculate the battery voltage value when the gas stove valve is closed, based on the determined current gas stove battery type.

[0062] In this embodiment, calculating the battery voltage value when the gas stove valve is closed specifically involves subtracting the battery voltage value before ignition from the voltage drop at the moment the valve is closed, corresponding to the current gas stove battery type. For example, if the gas stove battery type is determined to be alkaline, the voltage value when the valve is closed is the battery voltage before ignition minus the instantaneous voltage drop at the moment the valve is closed. If the gas stove battery type is determined to be carbon-based, the voltage value when the valve is closed is the battery voltage before ignition minus the instantaneous voltage drop at the moment the valve is closed.

[0063] Step S320: When the calculated battery voltage value when the gas stove valve is closed reaches the safety valve closing voltage threshold corresponding to the current gas stove battery type, it is determined that the gas stove battery meets the automatic valve closing setting conditions, and the automatic valve closing function is set.

[0064] In this embodiment, the safety valve-closing voltage threshold can be determined by subtracting the instantaneous voltage drop at valve-closing from the battery voltage value before valve closure. This voltage drop ensures the main controller operates normally during valve closure without triggering a reset. When the battery voltage at the time of gas stove valve closure is greater than or equal to the safety valve-closing voltage threshold corresponding to the current gas stove battery type, it can be determined that when the gas stove is turned off, the battery voltage will not drop below the main controller's operating voltage, preventing the microcontroller system from resetting due to the low voltage and failing to execute the valve-closing action correctly.

[0065] Reference Figure 4 In one embodiment, the gas stove battery detection and control method further includes:

[0066] Step S330: If the calculated battery voltage value when the gas stove valve is closed does not reach the safety valve closing voltage threshold corresponding to the current gas stove battery type, it is determined that the gas stove battery does not meet the automatic valve closing setting conditions, the automatic valve closing function setting is exited, and a low battery reminder is output.

[0067] When the battery voltage is lower than the safety shut-off voltage threshold corresponding to the gas stove's battery type when the gas stove is turned off or ignited, the battery voltage will drop below the main controller's operating voltage. This causes the microcontroller system to reset due to the low voltage, preventing it from properly closing the valve. Consequently, the gas stove cannot properly shut off the flame and will not respond to the user-set automatic shut-off function. In severe cases, this could even lead to a fire or dry burning risk, or affect normal use of the gas stove due to battery depletion. In this situation, the automatic shut-off function cannot be activated, and the user should be reminded that the battery is low and to replace it. If the battery voltage is lower than the safety shut-off voltage threshold, it is determined that the battery voltage is insufficient to support the automatic shut-off function. In this case, the gas stove should be put into a low battery mode, and the automatic shut-off function should be disabled. Entering low battery mode allows some functional modules of the gas stove's electronic control board, such as those related to automatic shut-off (e.g., wireless circuitry, timers, touchscreen), to enter sleep mode, reducing battery power consumption. Other functions, such as temperature and voltage detection circuits, can also be deactivated to further reduce power consumption and ensure basic functions like the audible and visual alarm circuit and main controller function normally even with low battery. In some embodiments, the gas stove control circuit also includes a low battery reminder circuit, which can be implemented using an audible and visual alarm circuit. When the battery voltage is detected to be less than or equal to a preset voltage threshold, the main controller generates a low battery signal, and the low battery reminder circuit issues an audible and visual alarm signal, such as playing a corresponding low battery voice reminder or illuminating an LED light to indicate low battery status.

[0068] The present invention also proposes a gas stove, including a memory, a processor, and a gas stove battery detection and control program stored in the memory and executable on the processor. When the processor executes the gas stove battery detection and control program, it implements the gas stove battery detection and control method as described above.

[0069] In one embodiment, the gas stove further includes a battery and a battery voltage detection circuit, wherein the battery voltage detection circuit is connected to the battery and the processor respectively.

[0070] In this embodiment, the battery voltage detection circuit can be implemented using a voltage detection switch control circuit based on the main controller. It is activated during operation to detect the battery voltage and output a corresponding voltage detection signal, and deactivated when not in operation, without detecting the battery voltage. Specifically, upon receiving a high-level voltage detection control signal, the voltage detection switch control circuit activates to detect the battery voltage and outputs the detected voltage detection signal to the main controller. Upon receiving a low-level control signal, the voltage detection switch control circuit deactivates, and the main controller does not receive the battery voltage detection signal. Thus, when not in use, the voltage detection switch control circuit can be deactivated, preventing the consumption of battery power and reducing the power consumption of the voltage detection switch control circuit and the main controller (which does not need to scan its feedback pin in real time to receive voltage detection signals). This invention can detect the battery voltage as needed without requiring real-time monitoring, effectively reducing the power consumption of the battery voltage detection circuit itself, thereby improving battery life and making it more energy-efficient and environmentally friendly.

All equivalent structural transformations made using the contents of the present invention's specification and drawings under the inventive concept of the present invention, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present invention.
