The control method of above-mentioned two embodiments is identical, and its detailed process is as described below:
Step one, signal acquisition
When the arbitrary described ignitor switch on gas-cooker is opened, just produce startup and control signal to described controller, described controller controls manipulator to described burnt gas valve and sends start signal, before described burnt gas valve control manipulator behavior drives described stove, valve is opened, the burner safety ignition burning of gas-cooker.
When whole described ignitor switch is closed, namely when whole furnace end of gas cooker is all in closed condition, produce closing control signal to described controller, described controller controls manipulator to described burnt gas valve and sends shutdown signal, before described burnt gas valve control manipulator behavior drives described stove, valve cuts out, and furnace end of gas cooker extinguishes safely.
Thus the gas leakage fault of pipeline between valve and gas-cooker before avoiding stove, because the gas leakage fault of most cases is all from the leakage of flexible pipe before stove and cooking stove, the security therefore used is greatly improved.
Step 2, gas leakage alarm
The safe concentration value of combustion gas in environment is stored in described controller, gas concentration in the real-time testing environment of described gas leakage alarming device, and detection signal real-time Transmission is compared to described controller and safe concentration value, when the gas concentration detected is greater than safe concentration value, warning will be produced, before described burnt gas valve control manipulator behavior drives described stove, valve cuts out, and the burner of gas-cooker extinguishes safely thereupon.
Gas leakage warning function can prevent when only having a furnace end of gas cooker in use, and leaking appears in gas pipeline or another burner of gas-cooker.When gas-cooker can also be prevented to be in closed condition, because service life is longer, there is components aging and the gas leakage produced.
Valve before step 3, automatic delay function stove
After infrared ray sensor detects human body signal, detection signal is transferred to described controller and carry out timing, when in timing N minute, again do not monitor human body signal, then described controller controls manipulator to described burnt gas valve and sends shutdown signal, before described burnt gas valve control manipulator behavior drives described stove, valve cuts out, and furnace end of gas cooker is extinguished safely.
In N minute of timing, again human body signal detected, then timing is from newly, described burnt gas valve controls manipulator and is failure to actuate, before described stove, valve is held open state, and the burner of described gas-cooker keeps fired state, and described N minute is adjustable settings parameter, according to the needs of cooking time, described N can be set as the numerical value such as 10,20,30.
This function is suitable for long-time gas-cooker when cooking while boiling (steam, stew) and do not need people's moment to pay close attention to gas-cooker, because cooking time is longer, a lot of people can select to be busy with other thing, easily forget that pot on gas-cooker is also hankered adding, cause pot to be dryouied, and gas-cooker burns away, hold fire hazardous, and the function of valve can record the kitchen operatorless time before this automatic delay function stove, valve before line delay of going forward side by side closes stove automatically thus avoid the generation of fire.
