Concise and to the point course of action of the present utility model:
Output dc voltage is as the control power supply after the filtering of capacitor C1 and resistance R 1 step-down, rectifier bridge rectification that diode D1-D4 forms and capacitor C2, voltage-stabiliser tube W1 voltage stabilizing for the alternating current 220V power supply, and LED 1 is indicated as power supply.
After connecting power supply, by capacitor C 4, the reset circuit that resistance R 10 is formed, produce reset pulse, 15 pin of input ic IC1 make the IC1 zero clearing that resets, 2,4, the 7 pin output electronegative potential of IC1,2 pin of IC2 are electronegative potential, the 1 pin output high potential of IC2, not adhesive of relay J, the normal opened contact J1 of relay disconnects, heating element heater RL must not be electric, and electric frying pan is in not heated condition.
When pressing soft-touch type button A1, the impulse circuit of being made up of button A1, capacitor C 3, resistance R 4 produces 14 pin that positive and negative saltus step pulse inputs to IC 1, makes the 2 pin output high potential of IC1, the 3 pin output electronegative potential of IC1, LED 2 is lighted, and expression is in the big fire function; The 2 pin output high potential of IC 1 is after resistance R 6, diode D5, thermistor RM dividing potential drop, make 2 pin current potentials of IC 2 be higher than 3 pin current potentials by resistance R 11, R9 dividing potential drop, make the 1 pin output electronegative potential of IC 2, the relay J adhesive, its normal opened contact J1 connects, the heating element heater RL heating of switching on.
Along with temperature of boiler rises, thermistor RM resistance reduces, when temperature of boiler reaches 300 ℃, 2 pin current potentials of IC 2 are lower than 3 pin current potentials, the 1 pin output high potential of IC2, and relay J discharges, its normal opened contact J1 disconnects, and heating element heater RL dead electricity stops heating; When temperature of boiler descended, thermistor RM resistance increased, and makes 2 pin current potentials of IC 2 be higher than 3 pin current potentials again, 1 pin of IC2 is exported electronegative potential again, and relay J is adhesive again, and its normal opened contact J1 connects, the heating element heater RL heating of switching on again so goes round and begins again.Because the multiplication factor of IC 2 is high, at the critical-temperature point, the minor variations of thermistor RM resistance just can make 1 pin current potential of IC 2 overturn, so control sensitivity is very high.
When pressing a soft-touch type button A1 again, produce 14 pin of a positive and negative saltus step pulse input ic IC1 again, make the 4 pin output high potential of IC1, the 2 pin output electronegative potential of IC1, LED 3 is lighted, and expression is in the moderate heat function; The high potential of the 4 pin output of IC 1 is through resistance R 7, diode D6, thermistor RM dividing potential drop, because resistance R 7 values are bigger than R6, so it is low when 2 pin current potentials of IC 2 are than the big fire function after dividing potential drop, when temperature of boiler during 200 ℃ of left and right sides, 1 pin current potential of IC 2 is upset just, and the temperature of moderate heat function is controlled at about 200 ℃.
When pressing a soft-touch type button A1 again, produce 14 pin of a positive and negative saltus step pulse input ic IC1 again, make the 7 pin output high potential of IC1,2, the 4 pin output electronegative potential of IC1, LED 4 is lighted, and expression is in little fiery function; The high potential of the 4 pin output of IC 1 is through resistance R 8, diode D7, thermistor RM dividing potential drop, because resistance R 8 values are bigger than R7, so it is low again when 2 pin current potentials of IC 2 are than the moderate heat function after dividing potential drop, when temperature of boiler during 140 ℃ of left and right sides, 1 pin current potential of IC 2 is upset just, and the temperature of little fiery function is controlled at about 140 ℃.
The value difference of resistance R 6, R7, R8 can make the heating-up temperature difference of big fire, moderate heat, little fiery three function shelves.
When pressing soft-touch type button A1 the 4th time, because the effect of diode D8, make the high potential of the 10 pin output of IC 1 be added to 15 pin of IC1, make IC 1 zero clearing that resets, make heating element heater RL stop heating.
Under arbitrary functional status, to press soft-touch type button A2 and can make IC 1 zero clearing that resets, heating element heater stops heating.
Mechanical temperature controller WK and thermal cut-off RR play double protection functions; when the electron temperature control section breaks down, when temperature of boiler surpasses the highest design temperature restriction; mechanical temperature controller WK and thermal cut-off RR action and fusing guarantee can not cause pot fusing of body heating plate.
The effect of resistance R 12, capacitor C5 is to make the upset of 1 pin current potential of IC 2 reliable more rapidly.
Thermistor can adopt NTC element or PTC element.
The utility model adopts electronic technology control; carry out function with a contact button and select (large, medium and small fire selection; the open and close of power supply); light emitting diode carries out function and shows, the disconnected element of employing mechanical temperature controller and hot melt carries out the duplicate protection under the failure condition, controls highly sensitive; dependable performance; it is good to have water resistance, uses advantages such as easy to operate, is the renewal product of present electric frying pan.
