The invention provides a detection and control method for a gas stove battery.

1, in an embodiment of the present invention, the gas stove battery detection and control method includes:

Step S100, obtaining the battery voltage value before the gas stove is ignited, and the battery voltage value when the gas stove is ignited;

It can be understood that in a smart gas stove, an electric control board, a main controller, and various detection sensors are provided. The electric control board of the gas stove can also be provided with a voice reminder circuit, a wireless circuit, a temperature detection sensor, Gas detection sensor, and LED indicating circuit, etc., to realize intelligent control of gas stove. In the smart gas stove, a battery is usually also provided, and the battery is electrically connected with the electric control board. When the gas stove is working, it supplies power to the above-mentioned circuit module, so as to realize the intelligent control of the gas stove. The battery can be an alkaline battery or a carbon battery. The battery is set in the gas stove, and can be specifically set in the knob body of the knob. The battery can be detachably set in the preset space in the knob body, or the battery can also be installed in the knob body. It can be integrated in the knob body and integrated with the knob body. The battery is used to provide electrical energy to each functional module on the electric control board of the gas stove. The battery can be realized by a primary battery such as a dry battery, or can be set as a rechargeable battery that can realize secondary charging. Specifically, the battery may be a rechargeable battery such as a nickel metal hydride (NiMH) battery, a lithium ion (Li-ion) battery, or the like.

In the gas stove, there are also micro switches, thermocouples, etc., and an ignition detection circuit can also be arranged on the electric control board. The micro switch can be set corresponding to the position of the ignition switch (gas rotary valve) of the gas stove, and based on The gas rotary valve is activated to close/open. For example, when the gas rotary valve is rotated to the preset position to realize valve opening and ignition, the micro switch is triggered and closed. The switch is triggered and disconnected.

The thermocouple includes a thermocouple probe set at the burner head and a thermocouple detection circuit integrated in the pulse igniter. Similarly, the electromotive force signal is obtained in real time, and the temperature of the burner head is sensed and the electromotive force signal is sent out through the thermocouple detection circuit. The thermocouple can also realize accidental flameout detection together with the valve stem rotation angle detector. The valve stem rotation angle detector detects the rotation angle position of the valve stem of the gas rotary valve and sends out the rotation angle position signal. When the rotation angle position signal is non-zero degree rotation When the angle position signal is used, it indicates that the gas rotary valve is in the open state. When the electromotive force signal drops from a high level state greater than a predetermined threshold (for example, 2mV) to a low level state lower than the lower predetermined threshold, it indicates that the burner is extinguished. It can be determined that the gas stove has unexpectedly turned off.

The ignition detection circuit can determine that the burner starts to ignite by detecting when the microswitch is closed, or when the electromotive force of the thermocouple jumps from a low state below a lower predetermined threshold to a high state above an upper predetermined threshold. The ignition detection circuit can detect the working state of the micro switch and the thermocouple to determine the working state of the gas stove.

In some embodiments, the gas stove is provided with a power start control circuit, the power start control circuit can receive the ignition trigger signal of the gas stove, and the power start control circuit works when the ignition trigger signal is received, and works when the ignition trigger signal is not received. When the signal is triggered, it remains inactive. That is, the power start control circuit can know the working state of the gas stove when the gas stove starts to work. For example, it can determine whether the gas stove starts to work by knowing the rotation angle of the ignition switch (gas rotary valve) of the gas stove. When working, the power start control circuit outputs an enabling control signal to the power conversion circuit, thereby controlling the power conversion circuit to work, so as to convert the electric energy of the battery and output it as a main controller, a voice reminder circuit, and a wireless circuit, The temperature detection sensor, the gas detection sensor, and the LED indication circuit are powered to realize the intelligent control of the gas stove. When it is determined that the gas stove has not started to work, the power start control circuit will not output the enable control signal to the power conversion circuit, the power conversion circuit will not work, and the output terminal of the power conversion circuit will not output the converted electric energy. At this time, the main controller, Voice reminder circuit, wireless circuit, temperature detection sensor, gas detection sensor, and LED indicating circuit are in working state without driving power. In this way, it is possible to control whether the power conversion circuit starts to work according to whether the gas stove is working or not, so that when the gas stove is not working, the power conversion circuit does not work, that is, the main controller 30 and the voice reminder circuit will not be notified. Wireless circuits, temperature detection sensors, gas detection sensors, and LED indication circuits are powered to reduce the standby loss of the gas stove.

In the gas stove, a gas stove pulse igniter is also provided. The gas stove pulse igniter is provided with a solenoid valve control circuit and a pulse ignition generator. The micro switch can be set corresponding to the position of the gas stove ignition switch (gas rotary valve). And close/open based on the triggering of the gas rotary valve. For example, when the gas rotary valve is rotated to the preset position to realize valve opening and ignition, the micro switch is triggered and closed. The switch is triggered and disconnected. By closing/disconnecting the micro switch, the working state of the pulse ignition generator and the solenoid valve control circuit can be controlled. When the micro switch controls the pulse ignition generator and the solenoid valve control circuit to work, the solenoid valve control circuit controls the current on and off of the solenoid valve coil to control the opening or closing of the solenoid valve suction valve. When the solenoid valve is opened, the combustion passage is opened, and at the same time, the pulse ignition occurs to control the ignition needle to generate a high-pressure spark, and the ignition is completed, so that the gas stove starts to work. This process is the ignition process of the gas stove.

This embodiment can detect the voltage of the battery when the power start control circuit controls the power conversion circuit to supply power to the electric control panel to determine that the gas stove is triggered, and use the voltage when the gas stove is triggered as the voltage before the gas stove is ignited. After the microswitch is closed for a certain period of time, or when the gas stove is in the ignition state according to the electromotive force generated by the thermocouple, the voltage of the battery can be detected, and the voltage when the gas stove is in the ignition state can be regarded as the ignition voltage of the gas stove.

Step S200: Determine the current gas stove battery type according to the acquired battery voltage value before the gas stove is ignited and the battery voltage value when the gas stove is ignited;

It can be understood that the gas stove solenoid valve belongs to the load with high power consumption in the gas stove. When the gas stove is ignited, the gas stove will consume a large amount of energy from the battery during the ignition and shutdown of the gas stove. In addition, different types of batteries used in gas stoves cause different voltage drops generated by the batteries when the gas is turned off. Similarly, the instantaneous voltage drops generated by the batteries during ignition are also different. For example, when the battery voltage is the same, the instantaneous voltage drop of the alkaline battery when the gas stove is closed (the battery voltage before the valve is closed minus the battery voltage when the valve is closed) is generally 0.2V, and the carbon battery is generally 0.2V when the gas stove is closed. The instantaneous voltage drop at the valve is generally 0.5V. In the same way, the instantaneous pressure drop of the alkaline battery when the gas stove suction valve (the battery voltage before the ignition suction valve minus the battery voltage when the ignition suction valve is ignited) is generally 0.2V, and the instantaneous pressure of the carbon battery when the gas stove closes the valve. The drop is generally 0.5V. Based on the above principles, in this embodiment, the battery type of the gas cooker can be determined by obtaining the battery voltage value before the gas cooker is ignited and the battery voltage value when the gas cooker is ignited, that is, according to the battery voltage drop before and after the gas cooker is ignited.

Step S300: When receiving the automatic valve closing function setting instruction, determine whether the gas stove battery meets the automatic valve closing setting condition according to the gas stove battery type and the battery voltage value, and perform the automatic valve closing function setting on the gas stove if so.

It should be noted that the working voltage of the main controller in the gas stove, such as the single-chip microcomputer, is usually 2V. If the gas stove is turned off or ignited, the battery voltage is pulled down and is lower than the working voltage of the main controller, resulting in the single-chip microcomputer. The system is reset because the voltage is pulled down, and the valve closing action cannot be performed normally. As a result, the gas stove cannot respond to the automatic closing function set by the user because the gas stove cannot be closed by the suction valve normally. In severe cases, there may even be a risk of fire or dry burning. Or the battery is not durable and affects the user's normal use of the gas stove. The automatic valve closing function setting instruction may be any one of the timing opening/closing valve function setting instruction, the countdown valve closing function setting instruction, the anti-dry function setting instruction, the intelligent recipe setting instruction, and the remote fire closing control setting instruction. or various combinations. For example, when setting the timed on/off function, the user can set the on time, off time, and set duration of the gas stove through a mobile terminal (mobile phone, smart bracelet, smart watch, tablet computer), etc. The terminal sends corresponding control instructions to the gas stove, and the user selects the timing time through the operation buttons of the mobile terminal, plays the standard operating procedure, and completes the cooking operation according to the standard operating procedure prompts. When receiving the automatic valve closing function setting instruction, it is necessary to determine the voltage drop when the gas stove battery type corresponds to the gas stove battery type when the gas stove is turned off. When the gas stove is turned off, the battery voltage drop will not reset the microcontroller, then It can be determined that the current battery voltage value of the gas stove satisfies the automatic valve closing setting condition. When the automatic valve closing setting conditions are met, the main controller and other circuit modules in the gas stove configure the corresponding parameters according to the automatic valve closing function setting instructions, such as the start time of the gas stove, the end time of the work, and the different firepower of each stage. The duration of the size, etc., to respond to the automatic fire-off function set by the user, and realize the intelligent control of the gas stove.

The gas stove control method of the present invention obtains the battery voltage value before the gas stove is ignited and the battery voltage value when the gas stove is ignited; voltage value, to determine the current gas stove battery type; to determine whether the gas stove battery meets the automatic valve closing setting conditions according to the gas stove battery type and battery voltage value when receiving the automatic valve shut-off function setting instruction, and if so, perform Automatic valve closing function settings. The present invention can ensure that the corresponding type of battery has sufficient power before the user needs to activate the touch screen to set the timer to turn off the fire, the anti-dry burning off the fire, the remote fire off and other functions of gas stove automatic fire off, as well as other intelligent functions, such as intelligent recipes. So that the intelligent function of the gas stove can be used normally, thereby improving the safety and reliability of the gas stove.

Referring to FIG. 2 , in an embodiment, in step S200, the step of determining the current gas stove battery type according to the acquired battery voltage value before ignition of the gas stove and the battery voltage value when the gas stove is ignited specifically includes the following steps: :

Step S210, according to the obtained battery voltage value before the gas stove is ignited and the battery voltage value when the gas stove is ignited, determine the pressure drop when the gas stove is under load;

In this embodiment, to determine the pressure drop when the gas stove is under load, the voltage value of the battery before the gas stove is ignited and the battery voltage value when the gas stove is ignited can be obtained by calculation, so as to obtain the voltage value of the gas stove before and after the battery is under load. The voltage difference value is obtained, wherein the voltage difference before and after the gas stove battery is loaded is the voltage drop when the gas stove is loaded.

Step S220: Determine the current gas stove battery type according to the difference between the voltage drop when the gas stove is under load and a preset voltage.

In this embodiment, when the battery voltage is the same, the instantaneous pressure drop of the alkaline battery when the gas stove closes the valve (the battery voltage before the valve is closed minus the battery voltage when the valve is closed) is generally 0.2V. The instantaneous pressure drop when the gas stove closes the valve is generally 0.5V. In the same way, the instantaneous pressure drop of the alkaline battery when the gas stove suction valve (the battery voltage before the ignition suction valve minus the battery voltage when the ignition suction valve is ignited) is generally 0.2V, and the instantaneous pressure of the carbon battery when the gas stove closes the valve. The drop is generally 0.5V. Based on the above principles, this embodiment can obtain the battery voltage value before the gas stove is ignited and the battery voltage value when the gas stove is ignited, that is, according to the voltage drop of the battery before and after the gas stove is ignited, before and after the gas stove is ignited. That is, the pressure drop when the gas stove is under load is compared with the preset voltage difference, and the battery type of the gas stove can be determined according to the comparison result of the two. As shown in Figure 3, the steps of determining the type of gas stove battery according to the comparison result of the two are as follows:

Step S221, when the voltage drop of the gas cooker under load is less than or equal to the preset voltage difference, determine that the current gas cooker battery type is an alkaline battery;

Step S222 , when the voltage drop of the gas cooker under load is greater than the preset voltage difference, determine that the current gas cooker battery type is a carbon battery. The preset voltage difference can be any value between the instantaneous pressure drop of the alkaline battery when the gas stove is sucking the valve, and the instantaneous pressure drop of the carbon battery when the gas stove is closed. When the instantaneous pressure drop of the stove suction valve is 0.2V, and the instantaneous pressure drop of the carbon battery when the gas stove closes the valve is 0.5V, the preset voltage difference can be set to 0.35V.

Referring to FIG. 4 , in one embodiment, when receiving an automatic valve closing function setting instruction, it is determined whether the gas stove battery satisfies the automatic valve closing setting conditions according to the gas stove battery type and the battery voltage value, and if so, the gas stove is performed on the gas stove. The steps for setting the automatic valve closing function include:

Step S310, according to the determined current gas stove battery type, calculate the battery voltage value when the gas stove closes the valve;

In this embodiment, the calculation of the battery voltage value when the gas stove closes the valve is specifically, the battery voltage value before the gas stove is ignited minus the battery voltage drop when the gas stove closes the valve corresponding to the current gas stove battery type, to obtain Calculate the battery voltage value when the gas stove closes the valve. For example, when it is determined that the current type of the gas stove battery is an alkaline battery, the voltage value of the alkaline battery when the valve is closed is the battery voltage before the valve is closed minus the instantaneous pressure drop of the alkaline battery when the valve is closed. When it is determined that the current type of the gas stove battery is a carbon battery, the voltage value of the carbon battery when the valve is closed is the battery voltage before the valve is closed minus the instantaneous pressure drop of the carbon battery when the valve is closed.

Step S320: When the calculated battery voltage value when the gas stove closes the valve reaches the safety valve closing voltage threshold corresponding to the current gas stove battery type, determine that the gas stove battery meets the automatic valve closing setting conditions, and perform the automatic valve closing function setting.

In this embodiment, the safety valve closing voltage threshold can be based on the voltage value of the battery type before the valve closing minus the instantaneous pressure drop when the valve is closed to meet the pressure drop value that keeps the main controller working normally when the valve is closed without causing reset. When the battery voltage value when the gas stove closes the valve 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 is pulled down and will not be lower than the main control The operating voltage of the controller causes the microcontroller system to be reset because the voltage is pulled down, and the valve closing action cannot be performed normally.

4, in one embodiment, the gas stove battery detection and control method further includes:

Step S330, when the calculated battery voltage value when the gas stove closes the valve does not reach the safety valve closing voltage threshold corresponding to the current gas stove battery type, determine that the gas stove battery does not meet the automatic valve closing setting conditions, and exit the automatic valve closing function settings, and output a low battery reminder.

When the battery voltage value when the gas stove closes the valve is lower than the safety valve closing voltage threshold corresponding to the current gas stove battery type, when the gas stove is turned off or ignited, the battery voltage will be pulled down and lower than the main controller's voltage. The working voltage will cause the MCU system to reset because the voltage is pulled down, and the valve closing action cannot be performed normally, which will cause the gas stove to fail to normally close the fire with the suction valve, and will not be able to respond to the automatic fire off function set by the user. In severe cases, it may even be possible There is a risk of fire or dry burning or the battery is not durable, which affects the user's normal use of the gas stove. At this time, the automatic valve closing function cannot be activated, and the user needs to be reminded that the battery is too low and the battery should be replaced. When the voltage value of the battery is less than the safety shut-off voltage threshold, it is determined that the battery voltage is not enough to support the automatic fire-off function. At this time, the gas stove needs to be controlled to enter the battery low-power mode, and the use of the automatic fire-off function is prohibited. Among them, when entering the battery low power mode, some functional modules of the electric control panel of the gas stove, such as functions related to automatic fire off, such as wireless circuits, timers, touch screens, etc., can be put into sleep mode, thereby reducing the power of the battery. power consumption, and some functions, such as temperature detection circuit and voltage detection circuit, can also be stopped to reduce battery power consumption and ensure some basic functions in the case of low power, such as sound and light alarm circuit, main controller, etc. normal work. In some embodiments, the gas stove control circuit further includes: the low battery reminding circuit may be implemented by an audible and visual alarm circuit. When it is detected that the voltage value of the battery is less than or equal to the voltage preset threshold, the main controller generates a low-battery signal, and the low-battery reminder circuit sends out an audible and visual alarm signal, such as playing the corresponding low-battery voice reminder, or by lighting the LED light, Make low battery reminders.

The present invention also provides a gas stove, including a memory, a processor, and a gas stove battery detection control program stored in the memory and runnable on the processor, where the processor executes the gas stove battery detection control program to achieve the above The gas stove battery detection and control method.

In one embodiment, the gas cooker further includes: a battery and a battery voltage detection circuit, the battery voltage detection circuit is respectively connected to the battery and the processor.

In this embodiment, the battery voltage detection circuit can be implemented by using the voltage detection switch control circuit based on the control of the main controller, it is turned on when working, detects the battery voltage, and outputs a corresponding voltage detection signal, and is turned off when it is not working , the battery voltage is not detected. Specifically, when a high-level voltage detection control signal is received, the voltage detection switch control circuit is turned on to detect the battery voltage, and output the detected voltage detection signal to the main controller. When receiving a low-level control signal, the voltage detection switch control circuit is turned off, the battery voltage is not detected at this time, and the main controller does not obtain a voltage detection signal of the battery voltage. In this way, the voltage detection switch control circuit can be turned off when not in use, and the battery power will not be consumed when the voltage detection switch control circuit is not in use, thereby reducing the voltage detection switch control circuit and the main controller (the main controller does not need to control the main control circuit in real time). The feedback pin of the device scans to receive the voltage detection signal) its own power consumption to the battery. The invention can detect the battery voltage according to the requirements without real-time detection of the battery voltage, and can effectively reduce the power consumption of the battery by the battery voltage detection circuit itself, thereby improving the battery's battery life and being more energy-saving and environmentally friendly.
