Fig. 2 is the circuit theory diagrams of the utility model device.

Now provide better embodiment of the utility model, do further principle explanation in detail according to Fig. 1 and Fig. 2.

As shown in Figure 1 and Figure 2, socket 1 is plugged the electric cooker attaching plug, puts the rice that has added suitable quantity of water well, and presses the electric cooker magnetic switch.Selector switch K2 pulls out to cooking one grade, energized K switch 1, and transformer B1 gets electric, by step-down, rectification and three-terminal regulator block 10 (present embodiment uses 7812 type integrated packages), output 12V direct-current working volts, power light D1 is bright.

Because selector switch K2 pushes the shelves of cooking to, the relevant pin of base integrated package 11 in the time of then (present embodiment adopts its pin 4 of NE555 type integrated package) ground connection, the time base ic circuit 11 oscillatory circuit nonoscillatory formed.The no count pulse input of digital integrated block 12 (present embodiment adopts the CC4020 type), its output pin (3 pin) no-output noble potential.

Among Fig. 2, by two OR-NOT circuit I in four the two input end rejection gate integrated circuit (for example CC4001 type) and II, its input/output terminal cross-couplings is formed R-S trigger 13.(also available Sheffer stroke gate 4011 is formed) is when alarm clock timing contact K3 or manual actuation of button AN1 connection, R-S trigger output noble potential, make triode Q1 (present embodiment adopts 9013 type triodes) conducting, the relay J adhesive, pilot lamp D2 is bright, contact J1, J2 throws (feeder ear that they all are connected civil power) respectively and connects with often opening of corresponding static contact, socket 1 power supply has, electric cooker begins the energising heating, socket 1 electric current is by shunt B2, induce the part electric current through diode D5 rectification, make triode Q2 (present embodiment adopts 9014 type triodes) conducting, the output electronegative potential, 14 paraphase become noble potential through rejection gate, make the input pin (5 pin) of rejection gate 15 get noble potential, another input pin (6 pin) is because of electronegative potential, and its output terminal (4 pin) is exported electronegative potential, thereby makes 11 output terminals (11 pin) of trigger II continue the output noble potential, relay J continues adhesive, and socket 1 continues energising.When the tripping operation of electric cooker magnetic switch, shunt B2 no current induction, then triode Q2 end noble potential, become electronegative potential through rejection gate 14 paraphase, two equal electronegative potentials of input pin of rejection gate 15, its output terminal output noble potential triggers R-S trigger 13, makes the SET output output LOW voltage, and triode Q1 ends, relay J discharges, contact J1 and J2 disconnect, and cut off the power supply on the socket, and cooking finishes.As long as then the user turns off power switch K1.
