[0043] In a first aspect, the embodiment of the present application provides a gas stove 10. Referring to Figure 1As shown, the gas stove 10 in this embodiment of the invention includes: a controller 101 and an ignition device 102 connected to the controller 101. Specifically, the controller 101 can be an MCU (Microcontroller Unit), also known as a single-chip microcomputer or a microcontroller. It also includes a memory 103, which stores code that can run on the controller 101. When the controller 101 executes the code, it implements the gas stove ignition control method of this embodiment of the invention.
[0044] Specifically, the memory 103 can be a ROM (Read-Only Memory) on a microcontroller. The ignition device 102 includes an ignition circuit 1021 and an ignition needle 1022 connected to the end of the ignition circuit 1021. The ignition circuit 1021 is connected to the controller 101.
[0045] Secondly, the gas stove ignition control method provided in this embodiment of the invention can be... Figure 1 The controller 101 of the gas stove shown executes to control the ignition device 102 to perform pulse ignition. (This will be combined with...) Figure 1 and Figure 2 The gas stove ignition control method provided in this invention will be described in detail with reference to specific embodiments.
[0046] refer to Figure 2 As shown, the gas stove ignition control method provided in this embodiment of the invention includes the following steps:
[0047] S101, in response to the ignition operation signal, sets the pulse discharge frequency.
[0048] The ignition operation signal is generated by the user's operation of the ignition component on the gas stove. When the controller detects the ignition operation signal generated by the ignition component, it sets the pulse discharge frequency.
[0049] In some implementations, the ignition operation signal is specifically generated by the user pressing the ignition knob on the gas stove. Based on the user's pressing of the ignition knob, the stop valve is triggered to open the gas path of the gas stove.
[0050] When the controller detects the ignition operation signal generated by the ignition component, it triggers a series of subsequent steps. Compared with related technologies that directly connect the power supply and ignition device based on the user's pressing operation, so that the ignition device can perform pulse ignition under power supply, this can avoid ignition pulse discharge caused by user misoperation.
[0051] Of course, for gas stoves that can be opened by other means, the ignition signal can also be generated by other forms of user operation, which will not be listed here.
[0052] In some implementations, the controller, in response to an ignition operation signal, outputs a digital pulse signal of a preset frequency to the ignition device to drive the ignition device to perform pulse ignition at a set pulse discharge frequency. The preset frequency is the same as the pulse discharge frequency. That is, the controller sets the frequency of the digital pulse signal output by the controller based on the set pulse discharge frequency, thereby enabling the ignition device to perform pulse ignition at a lower discharge frequency according to actual needs.
[0053] Specifically, the digital pulse signal in this embodiment of the invention can be a PWM (Pulse Width Modulation) signal. Compared to the ignition device which does not have a controller and only performs pulse discharge in a simple analog circuit manner, this embodiment of the invention drives the ignition device to perform pulse discharge by outputting a PWM signal of a preset frequency through the controller. As long as the preset frequency of the PWM signal is less than the inherent discharge frequency determined by the hardware parameters of the ignition device, the discharge frequency of the ignition device can be reduced, the number of discharges can be reduced, and energy saving can be achieved.
[0054] Generally speaking, using a simple analog circuit to achieve pulse discharge is limited by the hardware parameters of the ignition device, which determines the inherent discharge frequency in the range of 4Hz to 7Hz or even higher, and it is impossible to achieve a lower discharge frequency. Therefore, higher frequency pulse discharge causes greater wear and tear on the gas stove's battery.
[0055] like Figure 1 As shown, in related technologies, the ignition device is not controlled by a controller and includes a simulated ignition circuit. The battery is connected to the power supply terminal of the simulated ignition circuit, and the end of the simulated ignition circuit is connected to the ignition needle. It can be seen that the ignition needle is driven to perform pulse discharge entirely using the simulated ignition circuit, and the discharge frequency depends on the hardware parameters of the simulated ignition circuit itself.
[0056] refer to Figure 1 As shown, when the gas stove knob is pressed, the battery supplies power to the simulated ignition circuit. Under the influence of the battery voltage BAT, the voltage at EC1 in the simulated ignition circuit increases. Simultaneously, energy is stored through the energy storage circuit consisting of capacitor EC1, resistors R4 and R5, supplying power to the primary side of transformer T1. This energy is then transferred through T1 to the secondary side of transformer T1, supplying power to capacitor C2. When the voltage of capacitor C2 reaches a certain value, it discharges once. Therefore, the discharge frequency of the simulated circuit during pulse ignition is determined by the hardware parameters. Because the hardware parameters of the simulated ignition circuit are fixed, the discharge frequency of the secondary side is fixed and cannot be optimized.
[0057] In this embodiment of the invention, the controller is connected to the ignition device via its digital signal terminal. The controller outputs a PWM signal with a preset frequency in the range of 1 to 3 Hz to drive the ignition device to perform pulse discharge at the same frequency. This reduces the frequency of pulse ignition to the range of 1 to 3 Hz. Since the PWM signal can be set, the discharge frequency can also be set. The lower the set pulse discharge frequency, the fewer pulse discharges are performed in one ignition operation. Thus, a lower discharge frequency can reduce battery wear without affecting the probability of successful ignition.
[0058] Taking a pulse discharge frequency of 1Hz as an example, the ignition device can be successfully ignited after 3 to 5 pulse discharges. Compared with the inherent discharge frequency of 4-7Hz of the simulated ignition circuit, the required number of discharges can obviously be reduced to achieve successful ignition.
[0059] S102, Control the ignition device to perform pulse ignition based on the set pulse discharge frequency, and monitor the ignition status information during the pulse ignition process.
[0060] Since the gas still has a distance to travel from the gas valve to the burner head, if the controller does not detect and respond to the ignition operation signal, the battery will directly supply power to the analog ignition circuit after the user presses the knob. This will cause the analog ignition circuit to start discharging immediately, while the gas has not yet reached the burner head. This results in a certain period of ineffective discharge of the ignition device, leading to unnecessary energy loss.
[0061] In some embodiments of the present invention, when the controller detects an ignition operation signal, it opens the gas circuit of the gas stove and starts a timer. When the timer reaches a preset threshold, it outputs a PWM signal of a set frequency to the ignition device to drive the ignition device to perform pulse ignition at a set pulse discharge frequency. This achieves gas supply before ignition, avoiding ineffective discharge of the ignition device.
[0062] It should be understood that the preset time threshold can be set based on the time required for gas to reach the burner of the gas stove after the gas line is turned on. Therefore, the preset time threshold is related to the actual structure of the gas stove, and no specific numerical limit is given here.
[0063] In this embodiment of the invention, the ignition status information may include only information indicating whether ignition was successful, or may include both information indicating whether ignition was successful and the current number of discharge pulses of the ignition device.
[0064] S103. When the ignition status information meets the preset stop conditions, control the ignition device to stop pulse discharge.
[0065] If the ignition status information only includes information indicating whether ignition was successful; S103 specifically determines whether ignition was successful; when ignition is successful, the ignition device is controlled to stop pulse discharge.
[0066] If the gas supply is blocked or the gas supply is interrupted, the gas stove will fail to ignite regardless of the number of discharges by the ignition device. To save energy, the ignition status information includes both information indicating whether ignition was successful and the current number of discharge pulses from the ignition device. During pulse ignition, while determining whether ignition was successful, the system also monitors whether the current number of pulse discharges by the ignition device has reached a preset discharge threshold. If ignition is successful, the ignition device stops pulse discharge; otherwise, it continues to stop pulse discharge until the current number of pulse discharges reaches the threshold. Therefore, if either condition 1 (successful ignition) or condition 2 (current pulse discharge count reaching the threshold) is met, the ignition device will stop pulse discharge, thus avoiding ineffective discharges and reducing battery wear.
[0067] Specifically, the discharge count threshold is set based on experimental data, and is greater than the number of discharges required for the gas stove to successfully ignite under normal conditions. In this embodiment of the invention, the ignition device typically ignites successfully in 3 to 5 discharges, so the discharge count threshold can be set to a value greater than 5. To balance energy consumption and the probability of successful ignition in one operation, the discharge count threshold can be set to a slightly larger value, such as 7, 8, 9, or 10 times, etc.
[0068] In some implementations, a thermocouple probe can be installed on the gas stove. By detecting the thermocouple signal from the thermocouple probe, it can be determined whether ignition was successful.
[0069] Specifically, during pulse ignition, the thermocouple signal of the thermocouple probe installed on the gas stove is monitored; when the thermocouple signal meets the preset signal threshold, the gas stove is determined to be successfully ignited, and the ignition device is controlled to stop pulse discharge.
[0070] Specifically, the preset signal threshold is the thermoelectric potential range of the gas stove in combustion mode; the monitored thermocouple signal is the actual thermoelectric potential value representing the current state of the gas stove, collected by the thermocouple probe. If the actual thermoelectric potential value of the gas stove in its current state is within the thermoelectric potential range, it indicates that the gas stove has successfully ignited; otherwise, it indicates that the gas stove has not successfully ignited. In practical implementation, a sampling circuit can be set at the output end of the thermocouple probe to sample the thermoelectric potential value of the thermocouple probe, obtaining the sampled thermoelectric potential value as the actual thermoelectric potential value of the gas stove in its current state.
[0071] Of course, other methods can also be used to detect whether the gas stove ignites successfully. For example, after obtaining the actual thermoelectric potential value of the gas stove in its current state, it can be converted into temperature data; the temperature data can be judged to determine whether the combustion temperature threshold has been reached; if the combustion temperature threshold has been reached, it indicates that the gas stove has ignited successfully; otherwise, it indicates that the gas stove has not ignited successfully.
[0072] To enable those skilled in the art to better understand the technical solution of the gas stove ignition method provided in the embodiments of the present invention, the following will be combined with Figure 3 Let's take a microcontroller-based controller as an example to illustrate an implementation scenario:
[0073] S1: The user presses the knob on the gas stove, which opens the gas circuit by turning the stopcock valve.
[0074] S2: The microcontroller detects the pressing operation signal generated by the user pressing the knob, and starts power-on timing when the pressing operation signal is detected.
[0075] S3: The microcontroller determines whether the power-on timing duration has reached the preset threshold; if so, proceed to step S4: The microcontroller sets the pulse discharge frequency and discharge count thresholds for the ignition device. After S4, continue with step S5:
[0076] S5: The microcontroller outputs a PWM signal of a preset frequency to the ignition device to drive the ignition device to perform pulse ignition at the set pulse discharge frequency. Then, during the process of the microcontroller driving the ignition device to perform pulse ignition, steps S6, S6' and S7 are executed:
[0077] S6: The thermocouple signal of the thermocouple probe on the gas stove is sampled by the sampling circuit to obtain the thermocouple signal of the gas stove.
[0078] S7: The microcontroller detects the thermocouple signal sampled by the sampling circuit and determines whether the detected thermocouple signal meets the preset signal threshold; if so, proceed to step S8.
[0079] S6': The microcontroller determines whether the current discharge count has reached the discharge count threshold. If so, it executes step S8.
[0080] S8: The microcontroller controls the ignition device to stop pulse ignition.
