The specific embodiment:
As shown in Figure 1, switch AN pushes button, electric current is divided into two strands, one is by the key switch AN heat-generating disc R1 that flows through, another strand electric current is bright by the dropping resistor R3 indicator lamp ZSD1 lamp of flowing through, the diode VD2 that flows through again again through temperature control automatic switch ZK, forms the loop by overheating fuse RD after converging with electric current by heat-generating disc R1; Total power input heat-generating disc, reach design temperature 90-99 ℃ of temperature control automatic switch ZK and close the total power circuit, indicator lamp ZSD1 extinguishes, preestablish when cooking gear this moment, circuit enters energy-conservation moderate heat power rating immediately, flow through the electric current of heat-generating disc R1 through change-over switch HK, flow to diode D1 and become dc low-voltage input heat-generating disc R1 through the diode halfwave rectifier, the bright expression of indicator lamp ZSD4 that is connected in parallel on the diode two ends this moment is cooked and is entered the moderate heat state.Under the effect of low-voltage direct moderate heat power, cook behind the solid carbon dioxide, temperature raises gradually, after reaching Curie-point temperature, temperature limiter XW loss of excitation, the button AN outage of upspringing automatically, separately two strands of outage back input power supplys, one resistance-type warmer R2 that flows through, another strand electric current then passes through dropping resistor R4, insulation indicator lamp ZSD2, the series circuit of diode D3 converges the heat-generating disc R1 that flows through with preceding one electric current then, form the loop through temperature control automatic switch ZK (being lower than the closure that automatically resets about 80 ℃) by overheating fuse RD again, electronics pot enters 70 ℃ of left and right sides keeping warm modes, and ZSD2 is bright for the insulation indicator lamp.
If select pot congee (stewing) shelves, the AN electric current that pushes button equally is divided into two strands, one heat-generating disc R1 that flows through, another strand electric current is by dropping resistor R3, indicator lamp ZSD1, after the series circuit of diode D2 converges with the electric current of heat-generating disc R1 of flowing through again through temperature control automatic switch ZK, form the loop by overheating fuse RD, total power input heat-generating disc, reach design temperature 90-99 ℃ fast, ZK closes the total power circuit by the temperature control automatic switch, indicator lamp ZSD1 extinguishes, after temperature control automatic switch ZK closes, electric current connects two strands of electric currents of energy through R1 by change-over switch HK, one electric current forms the loop by overheating fuse RD behind indicator lamp ZSD3 and dropping resistor R5, pot congee indicator lamp ZSD3 promptly enters low baking temperature pot congee (stewing) state, meanwhile unidirectional thyristor VT is subjected to G utmost point triggering and conducting, to the low baking temperature power (being about 20% rated power) of heat-generating disc R1 input low-voltage direct setting.
As Fig. 2 and shown in Figure 4, between key switch AN and heat-generating disc R1 and dropping resistor R3, timer SK is housed, the switch AN that pushes button, electric current again through heat-generating disc R1, form loop through elasticity temperature control automatic switch ZK by timer SK through key switch AN.
As shown in Figure 3 and Figure 4, the unidirectional thyristor VT in the circuit changes into and adopts bidirectional thyristor VT.
IGCT automatic energy saving anti-overflow electronics pot of the present utility model, when the food when selecting pot congee or stewing function in stewing reaches 90-99 ℃, elasticity temperature control automatic switch cuts off the big fire power circuit, power supply is then because the G utmost point triggering and conducting of IGCT VT is imported about 20% rated power to heat-generating disc R1, pot congee low baking temperature indicator lamp is bright, under this state effect, set 20% low baking temperature rated power energy savings about 80% to greatest extent through repeatedly testing, and can keep 100 ℃ of little boilings for a long time, and can make pot congee, the not overflow that stews, water evaporates is few.Adopt timer, then the school transfers the required time to control automatically in advance, and is convenient like this.
