Eliminating or reducing these potential safety hazards is a tangible requirement for each consumer and is also a research and development direction for various large household appliance manufacturers. The control method for the gas stove mainly solves the problem of ignition protection in the whole cooking process of the one-key cooking stove, and has the advantages of being accurate and rapid in protection, high in protection accuracy and low in error protection probability.
Referring to fig. 4A, at any stage, if the temperature value of the pan bottom temperature sensor collected by the control device/the central controller is greater than the first set value 298 ℃ for more than 3 seconds, and the trigger mechanism/the micro switch at the lower part of the pan bottom temperature sensor is in a closed state, that is, the cooker is placed on the burner, the driving mechanism/the stepping motor is controlled to drive the plug valve to return to a zero position, the opening of the flow valve is driven to be minimum or closed, or the electromagnetic valve is controlled to cut off the air supply loop, so that the gas flowing into the gas stove is cut off, the gas stove is closed, or the panel LED is driven to display a dry burning error code at the same time, and the buzzer continuously prompts for 20 seconds at a frequency of 1 Hz. If the micro switch is in the off state at this time, the cooker leaves the cooking bench, the flow of the gas introduced into the gas cooker is gradually reduced according to a set time interval, for example, 10 seconds, namely, no prompt is carried out within 10 seconds, the internal timer is suspended, the stepping motor is controlled to drive the plug valve to reduce 2-gear firepower after 10 seconds, meanwhile, the panel LED is driven to display early warning of leaving the cooking bench, and the buzzer continuously prompts at 3HZ frequency; after 10 seconds, namely 20 seconds, the stepping motor is controlled to drive the plug valve to reduce to the lowest-grade fire power, meanwhile, the panel LED is driven to display a warning of separating from the cooking bench, and the buzzer continuously prompts at the frequency of 0.5 HZ; after 30 seconds, the electromagnetic valve is controlled to cut off the air supply loop, the stepping motor is controlled to drive the plug valve to return to the zero position, the panel LED is driven to display that the pot body/cooker is separated from the cooking bench for a long time, and the buzzer stops ringing. If the micro switch is closed again in the early warning and warning generation stage of the cooking bench, the early warning and warning state is eliminated, the stepping motor is controlled to drive the plug valve to restore the current firepower, the panel LED is driven to restore the cooking process display, the sound of the buzzer is eliminated, and the operation of the internal timer is restored.
According to the control method for the gas stove, the LED and the buzzer of the panel are used for pushing the fault alarm information to the user at the same time, different display contents and different buzzer sounding modes show different alarm meanings, and the control method has the advantages of being multiple in sensing mode and visual.
In the above scheme, the method further comprises: detecting the flame temperature of the gas stove; and in the ignition stage, when the flame temperature is smaller than a second temperature set value in a second set time, cutting off the gas introduced into the gas stove.

In the above scheme, the method further comprises: judging whether the temperature of the pan bottom/cooker detected by the pan bottom temperature sensor is within a set temperature range, and cutting off the gas introduced into the gas stove when the temperature of the cooker is not within the set temperature range or the pan bottom temperature sensor is short-circuited.
Referring to fig. 4C, after normal ignition, if the control device determines that the temperature sensor is disconnected or the temperature value is obviously abnormal in 2 minutes continuously, the electromagnetic valve is controlled to cut off the air supply loop, the stepping motor is controlled to drive the plug valve to return to the zero position, the panel LED is driven to display the abnormal prompt of the temperature probe, and the buzzer continuously prompts for 20 seconds at the frequency of 2 Hz.
