Fig. 3 B is a kind of flow diagram of control method for gas-cooker shown according to an exemplary embodiment.Such as
The control method for gas-cooker of one embodiment of the present invention shown in Fig. 3 B, further includes: in step S112, detection combustion
The temperature of cooker on gas kitchen；In the step s 120, it is passed through according to the adjusting of the temperature of the user instruction and the cooker described
The flow of the combustion gas of gas-cooker.
As an example, including: when described according to the flow that the temperature of the cooker adjusts the combustion gas for being passed through the gas-cooker
The temperature of cooker is greater than the first set temperature value, and when the cooker is not positioned on the burner, according between setting time
Every being gradually reduced the flow for being passed through the combustion gas of the gas-cooker.
In above scheme, further includes: when detecting that the cooker is replaced on the burner, adjusting is passed through described
The flow of the combustion gas of gas-cooker is restored to before reduction.
In above scheme, the flow for being passed through the combustion gas of the gas-cooker is adjusted according to the temperature of the cooker further include: when
The temperature of the cooker is greater than first set temperature value, and the cooker is placed in the time on the burner greater than first
When setting time, cutting is passed through the combustion gas of the gas-cooker.
Gas-cooker is cooking appliance important in Modern Family kitchen, due to using fuel gas buring as heating method, tool
There is certain risk, and due to kitchen range itself or user's oneself factor, it may be frequent occurrence such as loss of ignition, exception
Flame-out, pot body dry combustion method, the problems such as temperature is excessively high, lead to serious security risk.Eliminating or reduce these security risks is every
The practical demand of consumer and the R&D direction of major household appliances manufacturer.Exemplary embodiment of the present for gas-cooker
Control method mainly solves the problems, such as the ignition protection in a complete cooking process of key cooking stove, has protection accurately and fast,
Protect accuracy rate high, the advantage for accidentally protecting probability low.
With reference to attached drawing 4A, in any stage, if the collected cooking bottom temperature sensor temperature of control device/central controller
When the time that angle value is greater than 298 degrees Celsius of the first setting value is greater than the first setting time 3 seconds, and cooking bottom temperature sensor lower part
In the closure state, i.e., cooker is placed on burner trigger mechanism/microswitch, then controls driving mechanism/stepper motor band
Dynamic plug valve returns to zero-bit, drives the aperture of flow valve minimum or closes, or control solenoid valve is cut off for air circuit, so that cutting
It stops into the combustion gas of gas-cooker, closes gas-cooker, or can show DryFire error code by driving panel LED simultaneously, buzzer is with 1Hz
Frequency persistently prompts 20 seconds.If microswitch at this time is in an off state, illustrate it is that cooker has left hearth, according to setting
Time interval, such as be gradually reduced the flow for being passed through the combustion gas of gas-cooker for 10 seconds, i.e., without any prompt in 10 seconds, and it is interior
Timer pause in portion's controls stepper motor and plug valve is driven to reduce by 2 gear firepower after 10 seconds, while driving panel LED shows and takes off
From hearth early warning, buzzer is persistently prompted with 3HZ frequency；10 seconds control stepper motors i.e. after 20 seconds drive plug valve to be decreased to again
Deep low gear firepower, while driving panel LED display is detached from hearth warning, buzzer is persistently prompted with 0.5HZ frequency；It is controlled after 30 seconds
Solenoid valve cutting processed controls stepper motor and plug valve is driven to return to zero-bit, driving panel LED shows pot body/cooker for air circuit
It is abnormal too long to be detached from hearth, buzzer stopping pipes.If microswitch is again being detached from hearth early warning, alerting in stage of development
Closure, then early warning, alarm status are eliminated, and control stepper motor drives plug valve to restore current firepower, and driving panel LED restores
Cooking process is shown, is eliminated buzzer sound, is restored the operation of timer internal.
Control method for gas-cooker of the invention pushes failure report to user simultaneously by the LED and buzzer of panel
Alert information, different display contents and buzzer call mode indicate different alarm meanings, with more perceptive modes, intuitively
Advantage.
In above scheme, further includes: detect the flame temperature of gas-cooker；In ignition phase, in the second setting time,
The flame temperature is less than second temperature setting value, and cutting is passed through the combustion gas of the gas-cooker.
With reference to attached drawing 4B, in ignition phase, after ignition signal issues, control device central controller continuously detects flame temperature
The temperature value for spending sensor when detecting that temperature value obviously rises in 10 seconds, stops issuing ignition signal, if not examining in 10 seconds
It measures temperature value obviously to rise, then control solenoid valve is cut off for air circuit while stopping issuing ignition signal.
In above scheme, further includes: judge the bottom of a pan/cooker temperature of cooking bottom temperature sensor detection whether in setting temperature
It spends in range, when the temperature of cooker is not within the scope of set temperature or cooking bottom temperature short circuit sensor, then cutting is passed through the combustion
The combustion gas of gas kitchen.
With reference to attached drawing 4C, after normal ignition, if control device judges to detect within continuous 2 minutes that open circuit occurs in temperature sensor
Or temperature value it is obviously abnormal when, then control solenoid valve cutting for air circuit, control stepper motor and plug valve is driven to return to zero-bit, drive
Dynamic panel LED displays temperature probe abnormal prompt, buzzer are persistently prompted 20 seconds with 2Hz frequency.
As an example, further include: after the completion of igniting, in third setting time, the flame temperature is decrease beyond
Third desired temperature, and when the temperature of the cooker decrease beyond four desired temperatures, cutting is passed through the gas-cooker
Combustion gas.
With reference to attached drawing 4D, in any stage normally cooked, if flame temperature sensor is consecutively detected the temperature of flame
Degree is reduced with continuous downward trend more than 100 degrees Celsius suddenly, and cooking bottom temperature sensor is consecutively detected the bottom of a pan/cooker temperature
When degree slowly declines, solenoid valve cutting is immediately controlled for air circuit, controls stepper motor and plug valve is driven to return to zero-bit, drive surface
Plate LED shows accident extinguishing prompt, and buzzer is persistently prompted 10 seconds with 1Hz frequency.
As an example, further include: firing command is received, judges that the temperature of the cooker of the cooking bottom temperature sensor detection is
It is not no when being greater than five desired temperatures, if so, not executing firing command then.
With reference to attached drawing 4E, in guard mode, if the temperature value of the cooker of cooking bottom temperature sensor detection is Celsius greater than 280
Degree, then ignition function is invalid.
After normal culinary art starts, the culinary art duration of current generation is recorded by timer, is not occurred when in other protections
And after reaching the culinary art duration of terminal stage, the cutting of control solenoid valve controls stepper motor and plug valve is driven to return to for air circuit
Zero-bit, driving panel LED display culinary art normal termination information, buzzer are persistently prompted 20 seconds with 0.5Hz frequency, complete preset cook
The complete ignition protection function for process of preparing food.
Flow control system is arranged in the gas-cooker of embodiment of the present invention, to the flow of the combustion gas for flowing through fuel gas pipeline into
Row is adjusted, and is automatically performed the adjusting of flow, is improved the intelligent level and automatization level of gas-cooker.
