In a first aspect, an embodiment of the present invention provides a gas stove 10. Referring to fig. 1, a gas range 10 according to an embodiment of the present invention includes: a controller 101, and an ignition device 102 connected to the controller 101. The controller 101 may be an MCU (micro controller Unit), which is also called a Single Chip Microcomputer (Single Chip Microcomputer), or a Single Chip Microcomputer. The gas stove ignition control system further comprises a memory 103, codes which can run on the controller 101 are stored in the memory 103, and the controller 101 realizes the gas stove ignition control method in the embodiment of the invention when executing the codes.
Specifically, the Memory 103 may be a Read-Only Memory (ROM) on a single chip microcomputer. The ignition device 102 includes an ignition circuit 1021, and an ignition pin 1022 connected to an end of the ignition circuit 1021. The ignition circuit 1021 is connected to the controller 101.
In a second aspect, the ignition control method for a gas stove provided by the embodiment of the present invention can be executed by the controller 101 of the gas stove shown in fig. 1 to control the ignition device 102 to perform pulse ignition. A method for controlling ignition of a gas range according to an embodiment of the present invention will be described in detail with reference to specific embodiments in conjunction with fig. 1 and 2.
Referring to fig. 2, the ignition control method for a gas stove provided by the embodiment of the invention comprises the following steps:
and S101, responding to the ignition operation signal, and setting a pulse discharge frequency.
The ignition operation signal is generated by the operation of a user on an ignition component on the gas stove, and when the controller detects the ignition operation signal generated by the ignition component, the pulse discharge frequency is set.
In some embodiments, the ignition operation signal is, in particular: the user produces the operation of pressing down of knob of firing on to the gas stove, based on the operation of pressing down of user to the knob of firing, triggers the gas circuit that the plug valve opened the gas stove.
The controller is used for triggering a subsequent series of steps when detecting an ignition operation signal generated by the ignition component, and compared with the prior art that a power supply and an ignition device are directly conducted based on the pressing operation of a user, the ignition device is triggered to perform pulse ignition under the power supply of the power supply, and ignition pulse discharge caused by misoperation of the user can be avoided.
Of course, for a gas stove that can open a gas path in other ways, the ignition operation signal may also be generated by other forms of user operations, which are not listed here.
In some embodiments, the controller outputs a digital pulse signal with a preset frequency to the ignition device in response to the ignition operation signal to drive the ignition device to perform pulse ignition at the set pulse discharge frequency, wherein 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, so that the ignition device can perform pulse ignition at a lower discharge frequency according to actual requirements.
Specifically, the digital Pulse signal in the embodiment of the present invention may be a Pulse Width Modulation (PWM) signal, and compared with the case that the ignition device is not controlled by the controller, and only Pulse discharge is performed in a simple analog circuit manner, the embodiment of the present invention outputs the PWM signal with a preset frequency through the controller to drive the ignition device to perform Pulse discharge, so that 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, and the number of discharge times can be reduced, thereby saving energy.
Generally speaking, for pulse discharge realized by a simple analog circuit, the pulse discharge is limited by hardware parameters of an ignition device, the determined inherent discharge frequency is in the range of 4Hz to 7Hz, or even higher, and the lower discharge frequency cannot be achieved, so that the battery loss of the gas stove is larger by the pulse discharge with higher frequency.
As shown in fig. 1, in the related art, the ignition device is not controlled by the controller, and includes an analog ignition circuit, and the battery is connected to the power supply terminal of the analog ignition circuit, and the ignition pin is connected to the end of the analog ignition circuit, it can be seen that the ignition pin is driven to perform pulse discharge by completely using the analog ignition circuit, and the discharge frequency depends on the hardware parameters of the analog ignition circuit itself:
referring to fig. 1, when a knob of a gas cooker is pressed, a battery supplies power to an analog ignition circuit, under the action of a battery voltage BAT, the voltage at an EC1 position in the analog ignition circuit is increased, an energy storage circuit formed by a capacitor EC1, a resistor R4 and a resistor R5 stores energy to supply power to a primary side of a transformer T1, the energy is transmitted to a secondary side of the transformer T1 through the capacitor T1 to supply power to a capacitor C2, and when the voltage of the capacitor C2 reaches a certain value, primary power is discharged. Therefore, the discharge frequency of the analog circuit for pulse ignition is determined by hardware parameters, and the discharge frequency of the secondary side is fixed because the hardware parameters of the analog ignition circuit are fixed, and cannot be optimized.
In the embodiment of the invention, the digital signal end of the controller is connected with the ignition device, the controller outputs the PWM signal with the preset frequency within the range of 1-3 Hz to drive the ignition device to perform pulse discharge at the same frequency, so that the frequency of pulse ignition is reduced to the range of 1-3 Hz, and the PWM signal can be set, so that the discharge frequency can be set, the lower the set pulse discharge frequency is, the fewer the pulse discharge times under one ignition operation is, and the lower the discharge frequency can reduce the battery loss without influencing the ignition success probability.
By taking the set pulse discharge frequency as 1Hz as an example, the ignition device can successfully ignite after 3-5 pulse discharges, and compared with the inherent discharge frequency of 4-7Hz using an analog ignition circuit, the required discharge frequency is obviously less to successfully ignite.
And S102, controlling an ignition device, performing pulse ignition based on the set pulse discharge frequency, and monitoring ignition state information in the pulse ignition process.
Because there is a certain distance for the gas to reach the burner of the gas stove after the gas circuit is opened from the plug valve, if the controller does not detect and respond to the ignition operation signal, the battery can directly supply power to the analog ignition circuit after the user presses the knob, so that the analog ignition circuit can immediately start discharging, and the gas does not reach the burner, so that the ignition device has invalid discharging for a certain time, and unnecessary energy consumption loss exists.
In some embodiments of the present invention, when the controller detects an ignition operation signal, the controller opens the gas path of the gas stove and starts the timer to time; and when the timing duration reaches a preset duration threshold, outputting a PWM signal with set frequency to the ignition device so as to drive the ignition device to carry out pulse ignition at the set pulse discharge frequency. Therefore, the ignition is carried out after the gas is opened, and the invalid discharge of the ignition device is avoided.
Wherein, it should be understood that the preset time threshold may be set according to the time required for the gas to reach the burner of the gas stove after the gas path is opened. Therefore, the preset time period threshold is related to the actual structure of the gas range, and no specific numerical limitation is made herein.
In the embodiment of the present invention, the ignition state information may include only the information indicating whether the ignition is successful or both the information indicating whether the ignition is successful and the current number of discharge pulses of the ignition device.
And S103, controlling the ignition device to stop pulse discharge when the ignition state information meets the preset stop condition.
If the ignition state information only includes information indicating whether the ignition was successful; s103, specifically, judging whether ignition is successful or not; and when the ignition is successful, controlling the ignition device to stop the pulse discharge.
If the gas circuit is not communicated or the gas is stopped, the gas stove can not be ignited successfully all the time no matter how many times the ignition device discharges. In order to save energy consumption, the ignition state information comprises information for representing whether the ignition is successful and the current discharge pulse number of the ignition device; in the pulse ignition process, whether ignition is successful or not is judged, and whether the current pulse discharge frequency of an ignition device reaches a preset discharge frequency threshold value or not is monitored; and controlling the ignition device to stop pulse discharge when the ignition is successful, otherwise, controlling the ignition device to stop pulse discharge until the current pulse discharge frequency reaches the discharge frequency threshold value. Thus, under the condition one: successful ignition, condition two: when the current pulse discharge frequency reaches the discharge frequency threshold value and any one condition is met, the ignition device is triggered to stop pulse discharge, so that invalid discharge of the ignition device can be avoided, and battery loss can be reduced.
Specifically, a discharge frequency threshold is set according to the test result data, wherein the discharge frequency threshold is larger than the discharge frequency required by successful ignition of the gas stove in a normal state. In the embodiment of the present invention, the ignition device can be ignited successfully by discharging for 3 to 5 times, and the threshold value of the number of times of discharging may be set to a value greater than 5 times. In order to balance the consumption of energy and the probability of successful ignition of an operation, the threshold number of discharges may be set to a slightly larger value, for example, 7, 8, 9, or 10, etc. times.
In some embodiments, a thermocouple probe may be disposed on the gas stove, and whether ignition is successful or not may be determined by detecting a thermocouple signal of the thermocouple probe.
Specifically, in the pulse ignition process, thermocouple signals of a thermocouple probe arranged on a gas stove are monitored; and when the thermocouple signal meets a preset signal threshold, determining that the gas stove is successfully ignited, and controlling an ignition device to stop pulse discharge.
The preset signal threshold specifically comprises: the thermoelectric potential range of the gas stove in a combustion state; the monitored thermocouple signal is an actual thermoelectric potential value which is acquired by a thermocouple probe and represents the current state of the gas stove. If the actual thermoelectric force value of the gas stove in the current state is in the thermoelectric force range, the gas stove is indicated to be successfully ignited, otherwise, the gas stove is indicated to be unsuccessfully ignited. In specific implementation, a sampling circuit can be arranged at the output end of the thermocouple probe to sample the thermoelectric potential value of the thermocouple probe, so as to obtain a thermoelectric potential sampling value as an actual thermoelectric potential value of the gas stove in the current state.
Certainly, other methods may also be adopted to detect whether the ignition of the gas stove is successful, for example, after the actual thermoelectric force value in the current state of the gas stove is obtained, the actual thermoelectric force value is converted into temperature data; judging whether the temperature data reaches a combustion temperature threshold value; if the combustion temperature threshold is reached, indicating that the gas stove is successfully ignited; otherwise, indicating that the gas stove is not ignited successfully.
In order to make those skilled in the art better understand the technical solution of the gas stove ignition method provided by the embodiment of the present invention, an implementation scenario in which a controller is taken as a single chip microcomputer as an example is described below with reference to fig. 3:
s1, a user presses a knob of the gas stove to drive a plug valve to open a gas circuit.
And S2, detecting a pressing operation signal generated by pressing the knob by the user through the single chip microcomputer, and starting power-on timing when the pressing operation signal is detected.
S3, judging whether the timing duration of the power-on timer reaches a preset duration threshold value by the singlechip; if yes, step S4 is executed, wherein the singlechip sets the pulse discharge frequency and the discharge frequency threshold value of the ignition device. Continuing to execute S5 after S4:
s5, the singlechip outputs a PWM signal with a preset frequency to the ignition device to drive the ignition device to perform pulse ignition at a set pulse discharge frequency, and then, in the process of driving the ignition device to perform pulse ignition by the singlechip, steps S6, S6' and S7 are executed:
and S6, sampling the thermocouple signal of the thermocouple probe on the gas stove through a sampling circuit to obtain the thermocouple signal of the gas stove.
S7: the single chip microcomputer detects thermocouple signals sampled by the sampling circuit and judges whether the detected thermocouple signals meet a preset signal threshold value; if yes, go to step S8.
And S6', judging whether the current discharge frequency reaches a discharge frequency threshold value or not by the singlechip, and if so, executing the step S8.
And S8, controlling the ignition device to stop pulse ignition by the singlechip.
