Fig. 2 is a contour structures schematic diagram of the present utility model;

Fig. 3 is an electrical schematic diagram of the present utility model;

Fig. 4 is the electrical schematic diagram of power selection circuitry.

The utility model is described in further detail below in conjunction with accompanying drawing (embodiment):

With reference to Fig. 1, Fig. 2, the utility model is made up of switch triggering circuit 1, pulse-scaling circuit 2, function selector circuit 3,

gating circuit switch

4,5, coding circuit 6, Drive and Control Circuit 7, circuit for power conversion B, power circuit 9, body of heater 10, PVC thin film switch plate 11, electric hot plate 12 etc.Electric hot plate 12 is loaded in the body of heater of being made by high-temperature resistance plastice 10, and Electronic Control plate and temperature controller also are loaded in the body of heater 10, and PVC thin film switch plate 11 is loaded on the boiler face of body of heater 10.

With reference to Fig. 3, Fig. 4, moment behind power connection, reset capacitance C, resistance R work make pulse counter IC2 reset D ₀End is high level, and other outputs are low level, and this moment, electronic oven was not worked; After pressing ON/OFF K switch 1, the binary counter work of forming by d type flip flop IC1, its output Q becomes high level by low level, when body of heater does not have overtemperature, temperature controller T2 closure, the output signal of d type flip flop IC1 is input to the ST Enable Pin of pulse counter IC2 through temperature controller T2, allows pulse counter IC2 work, and promptly electronic oven is started working.Then, press firepower or culinary art key K2, K3 as required, the R end of rest-set flip-flop IC3 is input as 1, and this moment, its output Q was a high level, was used to control the ST end of gating switch IC5, made gating switch IC5 conducting.Simultaneously, press a pulse that firepower key K2 produces through or door F1 act on the CP end of pulse counter IC2, allow its counting, at this moment, output Q1～Q4 of IC2 exports corresponding level, level acts on coding circuit IC7 through gating switch IC5, behind the encoded circuit code, acts on BC1 to BG3, after amplifying, relay J 1, J2, J3 are acted accordingly, control electric hot plate at last, send corresponding power.

After pressing culinary art key K3, the Q end of rest-set flip-flop IC3 is 1, and when beginning to cook, food is boiling as yet, temperature controller T1 closure, and the Q end of rest-set flip-flop TC3 directly acts on 5 pin (1250W encode input) of IC7, thereby makes electronic oven export 1250W power; The Q of rest-set flip-flop IC3 end acts on and door A1 through T1 and not gate B1 simultaneously, makes it be output as low level, and gating switch IC4 temporarily quits work.When food seethes with excitement, T1 disconnects, 5 ends of IC7 are input as 0 (be 1250W power spread disappear), simultaneously, the Q end of rest-set flip-flop IC3 acts on and door A1 through T1 and not gate B1, makes it be output as 1, gating switch IC4 action, thereby make the output of pulse counter IC2 act on coding circuit IC7, make electronic oven export corresponding power through gating switch IC4.

The utility model has following advantage compared to existing technology:

1, manually control combines with automatic control, comprises insulation, low fire, moderate heat, high fire Etc. different thermal powers, to adapt to the various needs of culinary art.

Heating with full power when 2, culinary art begins during the food boiling, is adjusted to low-power automatically, Prevent from overflowing and adapting to the needs of slow fire culinary art, its process is all finished automatically, saves the energy.

3, novel structure, convenient and practical, safe and reliable, cost is not high, can replace existing electric furnace fully.
