8, Overall Power Consumption is low, changes one-shot battery and can use more than 1 year;
9, the computer timing controller is with low cost slightly, is fit to large-scale production.
The utility model microcomputerized control regularly concrete structure of gas-cooker is provided in detail by the following drawings and embodiment.
Description of drawings
Fig. 1 is the regularly circuit block diagram of gas-cooker of microcomputerized control;
Fig. 2 is the regularly circuit diagram of gas-cooker of microcomputerized control shown in Figure 1;
Fig. 3 is a regularly gas-cooker contour structures schematic diagram of microcomputerized control.
The specific embodiment
Embodiment: from Fig. 1 and Fig. 2 can be clear that microcomputerized control regularly gas-cooker form by gas-cooker and microcomputer timing controller, described microcomputer timing controller is by microcomputer control circuit 2, LCD display 1, adjusting knob 3, photoelectricity driver 4, buzzer 10, voltage detector 9 and battery 15 are formed, adjusting knob 3 is connected with microcomputer control circuit 2, each foot of microcomputer control circuit 2 connects respectively regulates button 3, LCD display 1, photoelectricity driver 4 and buzzer 10, the output of photoelectricity driver 4 insert the magnetic valve 5 and the igniter 7 of gas-cooker respectively.Magnetic valve 5 connects thermocouple 6, and igniter 7 is provided with ignition switch 11 and igniting pin 8 and thermocouple 6.On microcomputer control circuit 2 and photoelectricity driver 4 lines and be connected to voltage detector 9.Described gas-cooker 12 and the identical (see figure 3) of existing gas-cooker structure, gas-cooker 12 is provided with burner 13, button ignition switch 11 and air entraining pipe 14, and burner 13 is provided with igniting pin 8.The LCD display 1 of microcomputer timing controller and adjusting knob 3 are installed on the gas-cooker 12 kitchen range faces.
The utility model microcomputerized control regularly gas-cooker operation principle of gas-cooker is: when connecing down-firing button 11, igniter 7 produces high voltage, on burner 13, produce spark by igniting pin 8, combustion gas enters burner 13 by combustion gas skirt 14, lighted after running into the spark that sends of igniting pin 8, one direct current of igniter 7 outputs simultaneously is to the winding V2 of magnetic valve 5, make magnetic valve 5 be held open state, guarantee when thermocouple 6 fails to provide enough big electric current, can keep gas circuit unimpeded, after a period of time, this electric current is cut off automatically, also produce electric current after meanwhile thermocouple 6 is heated, this electric current is through the electronic switch K of photoelectricity driver 4, the winding V1 of magnetic valve 5 makes magnetic valve 5 be held open state, and it is unimpeded to keep gas circuit.When the stove fire accident was extinguished, thermocouple 6 turned cold and can not produce electric current, then magnetic valve 5 be closed, thereby reach the purpose of accident extinguishing protection.
