Among Fig. 2, air valve opener 3 comprises travel switch S1～S3, pinion 19, travelling gear 20, double-screw bolt 21, gear train 22, gear wheel 23; Discharge valve control mechanism 7 comprises pinion 26, travelling gear 27, double-screw bolt 28, gear train 29, gear wheel 30; The automatic opener 10 of water valve comprises pinion 33, travelling gear 34, double-screw bolt 35, gear wheel 36.During real work, air valve drive motors N2 can drive pinion 19 and rotate, pinion 19 rotates by travelling gear 20, double-screw bolt 21 driven gear groups 22, pinion in the gear train 22 drives gear wheel 23 again and rotates, rotate thereby can drive coal gas regulating shaft core 24, reach and open air valve and regulate what purpose of tolerance.In like manner, penstock drive motors N1 and discharge drive motors N3 can reach automatic unlatching water valve by gear drive and regulate what purpose of discharge.Whether the phototriode BG1 in the Photoelectric Detection kindling material circuit 5 is loaded on the next door of kindling material pipe 40 in addition, light so that detect kindling material.

Among Fig. 3, firepower by-pass cock K1, K2 and discharge by-pass cock K3, K4, time-out pass taps K6 and power switch K5 are housed on the panel of remote controller housing 39; And kindling material indicator lamp LED1, power supply indicator LED2 are housed, water valve suspends indicator lamp LED3; Temperature display 41 also is housed.

With reference to Fig. 4, central control circuit 1 comprises IC 4(model μ PD7538) and peripheral cell etc.; Air valve drive circuit 2 comprises IC 2 and peripheral cell etc.; Photoelectric Detection kindling material circuit 5 comprises photosensitive tube, triode BG2, luminous tube LED1 etc.; Under-voltage protection circuit 6 comprises triode BG3, Zener diode D7 etc.; Discharge drive circuit 7 comprises IC 8 and peripheral cell etc.; Penstock drive circuit 9 comprises IC 6 and peripheral cell etc.; Electronics self-lock switch circuit 11 comprises IC 1, IC2 and peripheral circuit, power switch K5, luminous tube LED2, LED3 etc.; The water yield is regulated indicating circuit 12 and is comprised IC 10, luminous tube LED4～LED8 etc.; Firepower is regulated display circuit 13 and is comprised IC 9, luminous tube LED9～LED13 etc.; The delivery port temperature-sensitive detects and temperature display circuit 14 comprises temperature-sensitive triode TR, IC 5 and peripheral cell, display screen 41 etc.; Temperature-sensitive detects and amplifying circuit 16 comprises thermistor T1, T2, IC 3 and peripheral cell etc.; Comparison circuit 17 comprises IC 11 etc.; Power circuit 18 comprises transformer B, rectifier bridge Z, three terminal regulator IC12, dc-battery E, capacitor C 5, C6 etc.

During actual the use, send an impulse level to give IC1 by K switch 5, IC1 is a phase inverter, constitutes self-locking; Owing to will eliminate the shake that mechanical switch causes, ad hoc IC2, IC2 are the homophase device, eliminate unnecessary pulse jitter.Deliver to 9 pin of IC4 at the level of IC2 output, notify its drive IC 7 to start, motor N2 rotates, and promotes the valve opening of valves, by cam depression stroke switch S 1, makes electronic impulse ignition apparatus work.Because at the kindling material pipe 40 other photosensitive tube BG1 that are provided with, detect kindling material by BG1, after confirming that kindling material has been lighted, the BG1 conducting makes 18 pin of IC4 become low level, and 37 pin are sent high level, notice IC7 restarts, by the gear cam travel switch S2 is connected, automatic stop, the distance between the travel switch S2 to S3 is kept closed.All travel switches all are arranged at (following all travel switches are all same as described above, no longer describe in detail) on the desired location.Because S2 conducting, 22 pin of IC4 are sent high level to IC6, make motor N1 get electric operation, make penstock open automatically that (travel switch S6, S7 are penstock end switch, when penstock is opened when most, cam can jack-up S6, S7 make its disconnection, the automatic stall of N1), has only the control kindling material just to open water valve after lighting like this, promote main burner 42 by the aqueous vapor linkage, main burner just has a large amount of gas firings, avoids a large amount of fuel gas to leak and causes the accident.K6 establishes for suspending pass water, but keeps in a fire, and the water temperature during the user bathes like this behind the wiping soap is constant at the water temperature of setting by before the K6; After if K6 presses, the 33 pin level counter-rotatings of IC4 can make 23 pin of IC4 become high level, and 22 pin become low level, and because of IC4 inside is provided with from changing lock function, IC6 does the counter-rotating startup and closes.Just open water valve after can effectively controlling kindling material like this and lighting, kindling material is because the accident extinguishing motor also can do auto-reverse cutting out.S1 is the Automatic stop switch that resets.

Confirming just can to press K1, K2 after the S2 closure, K1, K2 just respond.When K1 presses, can send into 19 pin of IC4, make it become low level, send high level at 36 pin, 5 pin of IC1 are high level also, N2 just changes, and transfers big firepower; When pressing K2, can make 40 pin of IC4 become low level, 37 pin output high level, 6 pin of IC7 are high level, make the N2 counter-rotating, turn firepower (K1, K2, K3, K4 are the switches of not establishing auto-lock function) down.

Because to be closed to the S3 position is the firepower regulatory region to S2, the position establishes at this that 9 pin of IC4 remain high level on stroke, and K3, K4 just respond when at this moment having only 33 pin of IC4 to be high level, regulate.Press K3,34 pin of IC4 are high level, and 6 pin of IC8 are high level, motor N3 just changes, and transfers big discharge, in like manner, press K4,35 pin that make IC4 are high level, and 34 pin become low level, motor N3 counter-rotating is turned discharge down, when the discharge valve is transferred to the maximum end, cam meeting jack-up travel switch S4, S5,33 pin that make IC4 are low level, press K3, K4 again, and motor is not reaction also.

This circuit is provided with mu balanced circuit (3.5V) for IC4(CPU) and other IC usefulness, also be provided with anti-low voltage circuit in addition, when as long as the reserve battery discharge is lower than 3.5V, 1 pin of IC4 will become low level, IC4 automatically resets zero clearing then, makes all valve closings, prevent that effectively battery from using up, motor no longer then make water heater out of control.

The burning fire will change during the water heater anoxic, steam stove top than bottom heat several times more than, this circuit utilizes this physical characteristic, be equipped with the variation in combustion that thermistor T1, T2 monitor water heater in the top and the bottom of water heater, the data that detected by T1, T2 are amplified with delivering to comparator IC11 after the impedance conversion again by IC3, deliver to 30 pin of IC4 again by comparator, and just often 30 pin are low level, 30 pin just become high potential during anoxic to 18%, carry out self-locking.All do not have effect by any button after the self-locking, only remain just to have been answered when 30 pin are reduced to electronegative potential startup.

Include IC 1, IC2, IC5, IC9, IC10 in the remote controller housing 39; When carrying out the adjusting of the firepower and the water yield, IC9 and IC10 can distinguish driving LED 4～LED8 and LED9～LED13, show current program.IC5 is the special-purpose integrated package of digital temperature in addition, and it includes A/D conversion and digital drive etc., and it can directly drive LCD liquid crystal board 41 by the detected signal of temperature-sensitive pipe TR, shows water temperature.
