As improvement of the technical scheme, described microcomputer-recognized intelligent control system comprises single-chip microcomputer U2, stabilized power source 1, electric leakage, calandria temperature alarm circuit 11 and output power controlling circuit 3 compositions; Wherein U2 is programmable single-chip microcomputer; Stabilized power source 1, output power controlling circuit 3, electric leakage, calandria overheating protection circuit 4, inflow temperature sensor 6, leaving water temperature sensor 7, Hall current sensing device 9, electric leakage sniffer 10, electric leakage, calandria temperature alarm circuit 11 all link to each other with single-chip microcomputer U2; Civil power through anti-dry protection, be connected serially to electric heater RL1 and controllable silicon VT1, VT2, transformer T1 is elementary, U2 outputs signal to display control section.Display control section comprises that temperature display, temperature are provided with part and U3, U3 are the VFI drive circuits; Single-chip microcomputer U2 outputs signal to display control section 8.
In the technique scheme, the leaving water temperature of water heater is 32～55 ℃.
The course of work of the present invention is as follows:
1, after the connection AC power, the 220V civil power is delivered to transformer T1 and divided three tunnel inputs after L2 filtering: the one tunnel for the VFD1 filament voltage, one the tunnel obtains a 20V DC voltage through diode D5, capacitor C 5 filtering, this voltage provides drop-down level VEE for the drive circuit integrated package, adds to 22,23 pin of VFD simultaneously again by current-limiting resistance R40.Another road is through diode D1, D2 full-wave rectification, capacitor C1, C2, C3, C4, stablizes and obtains the 5V DC voltage behind piece U1, inductance L 3 voltage regulation filterings and offer U2～U5, and the 12V DC voltage offers relay K 1.
2, in the circuit diagram, L1 is the electric leakage transformer, when normal nothing is leaked electricity, the live wire of direct puncture transformer, zero line are elementary as transformer, and this moment, the resultant flux amount was zero, and secondary influence electricity miscarriage is given birth to, triode Q1 base stage Triggerless, relay K 1 is failure to actuate, and electric heater normally generates heat.When live wire and the earth electric leakage of human body contact live wire or heater element RL1, thereby shock current does not directly reflux from zero line from live wire and ground leakage, and this moment, transformer resultant flux amount no longer was zero.The secondary induced current that produces immediately of transformer, arrive 18 pin of single-chip microcomputer U2 by diode D3, resistance R 3, trigger triode Q1, output low level, make triode Q4 by, relay K 1 dead electricity through the 5 pin output currents of U2, stop heating, 20 pin of U2 output simultaneously is about the pulse current of 30Hz.Drive LED 1 stroboscopic.
3, discharge is gathered 19 pin of giving single-chip microcomputer U2 through 1 pin output, 10.2～75Hz of binding post JP2 pulse, obtain control signal, remove to regulate the heating power of water heater, collection is through going out water sensor RP6, water inlet sensor RP7 resistance R 4, R5,13 of single-chip microcomputer U2 is given in capacitor C 8 sampling backs, 14,15,16 pin, by single-chip microcomputer U2 calculation deviation amount (being the poor of set temperature value and actual temperature value), and deviate handled, deviate is calculated by PID, regulate proportionality coefficient, integral coefficient, differential coefficient, thus the ideal control temperature effect obtained.
4, U3 is the VFD drive circuit of 1/4～1/11 dutycycle.Comprise 11 section delivery outlets, 6 grid delivery outlets, 5 section/grid are selected delivery outlet, 1 display-memory, control circuit, key scanning circuit.Scurry line data and remove to control VFD1 display screen driving integrated package by 26,28,29 pin that CTL, CLK, DIN3 line serial line interface are connected to single-chip microcomputer U2, the leaving water temperature design of water heater is between 32 ℃～55 ℃, the variation of departure is in a byte, adopt the single byte plus and minus calculation, at last result of calculation is converted into the T0 initial value regularly with control.Each start leaving water temperature is designed to 40 ℃, can adjust coolant-temperature gage by key switch S1 (ADD adds), S2 (SUB subtracts) key, when inflow temperature surpasses when temperature is set, and triode Q4 high level block system relay K1, corresponding heating element heater RL1 does not work; Then heat automatically on the contrary.When leaving water temperature surpassed 55 ℃, 5 pin of single-chip microcomputer U2 output triggering signal was given triode Q4, exports high even breaks electrical equipment K1 through Q4, and corresponding heating element heater RL1 quits work, and can prevent to scald.
5, power output: this circuit adopts soft start control controllable silicon VT1, VT2, to reduce the interference of dash current to other household electrical appliance.Start timer at alternating voltage zero-crossing point, and close 2,4 pin of delivery outlet U2, when timer overflows, produce and interrupt.Enter and interrupt the controllable silicon conducting, when next zero crossing arrived, controllable silicon turn-offed voluntarily, continues to close simultaneously 2,4 pin of delivery outlet U2, started timer.So repeatedly, can produce the phase shift effect, control controllable silicon V T1, VT2 conducting degree obtain different heating power at delivery outlet, thereby realize the constant temperature water outlet.
6, after VFD drive integrated circult U3, CTL, CLK, DIN scurried row mouthful picked up signal, 1 pin of U3 outputed signal to 3 pin of display screen and lights the shower head sign; The 2 pin output signals of U3 are lighted 4 pin of display screen, and corresponding site is trade mark AWT, temperature; The 3 pin output signals of U3 are lighted 5 pin of display screen, promptly digital d section; 4,5,7～18 each pin output signal of U3 are lighted display screen charactron a, b, c, d, e, f, each section of g; 19～21 pin output signals of U3 are lighted display screen heating sign, reflect the progressively process of heating. VFD display screen 1,2,22,23 each pin are the input of 3V alternating voltage.
