Description

Intelligence type gas-burning water heater

The utility model relates to a kind of daily necessities, especially the improvement of combustion gas heating bathing implement structure.

The gas heater (hereinafter to be referred as water heater) of producing in the world now and using is broadly divided into direct exhaust, flue gas formula and balanced type water heater by its exhaust mode.Directly exhaust water heater cost is low, easy for installation, is easy to be accepted by the user.But use in the place that this water heater only allows to be installed in the bathroom separate ventilation, if be installed in the bathroom, wants oxygen consumption during flame combustion, also wants combustion gas, particularly CO gas, can cause people's anoxic or poisoning, also can be dead when serious.And be installed in bathroom separate ventilation place, and use and very inconvenient, abnormal conditions occur and also be difficult for being found, this is its bad place.Flue Gas Water Heater is exactly that direct exhaust water heater exhaust gas discharged is guided to outside the bathroom with flue, and the phenomenon that the waste gas poisoning takes place is greatly reduced.But oxygen consumption can cause people's anoxia asphyxia in the time of can not avoiding fuel gas buring, has also increased cost and installation difficulty, and flue has leakage slightly, also can endanger people's health.The balanced type water heater is exactly the admission line that increases again on the Flue Gas Water Heater basis for the required fresh air of burning, and like this, the balanced type water heater just can compare being installed in the bathroom of safety have been used, and has brought into play water heater advantage easy to use.The installation of this water heater is very complicated, every index is all had relatively high expectations, also relatively harsher to environment (the comprising building structure) condition of installing and using, manufacturing cost is also high, if any damage, the shower people can suffer damage under condition of unknown, exists potential danger.For guarantor's life security and healthy, water heater preferably is installed in the place of bathroom separate ventilation.National departments concerned is expressly provided: " every gas heater that is installed in the bathroom must move to outside the bathroom without exception, to guarantee the well-ventilated ".

Existing water heater is installed in the place of bathroom separate ventilation and uses, though ensured safety, but: 1, for the size of switch water and regulating pondage, water inlet pipe must be through the bathroom, and set up water valve in addition for bather's operation in the bathroom domestic demand, water valve on the former water heater is just on the shelf, has increased installation cost and difficulty.

2, for safety, air inlet pipe and intake valve can not be pacified into bathroom, so just bring a lot of inconvenience to use.Need regulate water temperature during shower and close that gas is flame-out (for safety with do not damage water heater, to be stipulated on its operation instructions: " close water after should closing gas earlier when shower finishes.") time, usually need to help operation the people outside the bathroom with the mode of propagandaing directed to communicate.

The water heater of prior art also has the following disadvantages:

1, igniter: both bothered with match igniting and gas lighter sparking mode except that original, waste combustion gas again, outside the combustion gas of releasing out also is pernicious to people, adopt the piezoelectric ceramics igniting now more, require great effort when this device uses, and the rate of lighting is not high, service life is not long yet, adopts heating wire to light a fire in addition, and its response speed is slow, energy consumption is big, and the life-span is short.The multiterminal ignition that Liaoning Radio Factory No.2 produces has been used for kitchen range, but lights a fire, opens the formality of gas twice; On November 4th, 1987, the utility model CN87200197U of the Decree of Patent Office of China adopted: rotation knob adjustable air flow amount, and promote knob and can carry out the electronics scheme of igniting continuously, also only be used for kitchen range, and igniting also needs manual operation.

2, flame-out protection device: in recent years; the flame-out protection device that Japan Song Xia company produces is that a thermocouple is set on start-up burner, when the start-up burner flame combustion, and the vehement burning thermocouple of flame and produce electromotive force; make electromagnetic actuation, open air valve.(opening time is 10 seconds to 45 seconds but the thermocouple response time is slow, standard GB 6932-86 regulation is not more than 45 seconds), so that after whenever lighting start-up burner, must continue to push air valve knob at least air valve is opened, operation not only bothering but also require great effort; After flame-out, also get (15 seconds to 60 seconds several seconds, GB GB6932-86 regulation is not more than 60 seconds) could close gas check valve, cause gas leakage, and flame-out back (may because of reasons such as winds) be in the time of need lighting a fire again, the shower people must walk out the air valve of operating on the water heater in the bathroom and light a fire again, uses very inconvenient.Moreover flame-out in washing process, the shower people is ignorant, can cause a large amount of gas leakage, and becomes cold water suddenly, to shower people (particularly old, weak, young, patient), can be very strong stimulation, produces adverse consequences.

3, in the shower process, the shower people can't understand the ruuning situation of water heater.

4, the two places because water heater and shower people live apart, make operation inconvenience, so that after the people that takes a shower washs usually and finishes, get only abuse and close water earlier, just can go out the bathroom after getting dressed and close gas, both waste energy like this, cause easily that again water heater produces overheated and damages, especially go out when forgetting about closing gas behind the bathroom (this situation happens occasionally) the easier adverse consequences that causes.

When 5, adopting the high-voltage spark igniting, ignitor often by start-up burner flame baking or vehement burning, makes its lost of life, and can make sparking ineffective to the pollution of electrode (as dust etc.) behind the flame combustion.The product of Japan pine summer electrical equipment company has adopted auxiliary ignition device, though overcome the disadvantage of the vehement burning ignitor of flame, complex structure, the rate of can lighting has also reduced, gas leakage and the also corresponding increase of probability that damages.

6, very big at air pressure, use under the very little situation of hydraulic pressure, water heater has and produces overheated possibility, both hurts sb.'s feelings easily, damages water heater again easily.GB GB6932-86 regulation: " when the import cold water temperature was 10 ℃～20 ℃, water heater outlet hot water temperature should be above 65 ℃ ".Like this, the designer can reduce main burner quantity, but the response speed of the heat production water that but slowed down, and the GB regulation is not more than 45 seconds heat time heating time.These indexs all do not have the facility that can effectively control in the prior art.

7, GB GB6932-86 regulation: (when Guan Shui suspends) " temperature rise of cutting off the water is no more than 18 ℃ " prior art does not also have this type of restriction facility, cause when taking a shower, after Guan Shui suspends use (as smearing soap etc.), when re-using, always there is one section high temperature current to flow out, accidentally will hurts sb.'s feelings.

8, hydraulic pressure problem: water heater spreads to huge numbers of families and various occasion, only just existing nearly 600,000 domestic gas-fired water heaters of Chinese market come into operation, the source pressure of its use also has nothing in common with each other, concerning water heater, totally withstand voltagely design greatly, accommodation is just wide, but cost up, weight also strengthens; Design for a short time, hydraulic pressure is once leaking easily greatly and damaging.GB 6932-86 has made regulation to various water heater withstand voltage properties: " at 1.25MPa, the hot high pressure hydrophone is under 2.0MPa hydraulic pressure at 0.5MPa, middle pressure water heater for the low pressure hot water device, and lasting 2 minutes should be water-tight.”

9, have water heater now in use, in a single day if first boiling water is opened gas again, will leak gas in a large number before lighting (because of the main burner gas circuit is unlocked) at this moment lights, and will produce the combustion of Hong a sonic boom, also can set off an explosion when serious.

10, existing water heater can not assigned temperature output hot water, and after the start, the bather regulates the aperture of the gentle flow control valve of Water flow adjusting valve repeatedly with the sensation of oneself, just can be adjusted to the suitable water yield and water temperature.

11, existing water heater is opened gas, igniting, is closed valve again when unignited or flame-out, opens gas again, again igniting, shower finish Shi Xianguan gas, Hou Guanshui, putting Yu Shui (after low temp area uses, makes pipe breakage and damages as not emitting the surplus water in the water heater, will freezing.) wait by the bather and operate item by item.

The purpose of this utility model provides a kind of gas heater with intelligence, and it can solve the deficiencies in the prior art effectively, can realize following purpose:

1, water heater of the present utility model also can be produced direct exhaust, flue gas formula and balanced type.For safe in utilization, use in the place that should be installed in the bathroom separate ventilation, and water inlet pipe, air inlet pipe, water valve, air valve all needn't be pacified into bathroom, also removed the operational degree item by item that prior art is required great effort very much from, be provided with the packaged type operating unit, can be installed on the water heater, also can operate functions such as the start of water heater, regulating pondage, adjusting water temperature, hot and cold water selection, shutdown easily as operating colour television set in other place (in the bathroom) away from water heater;

2, can realize the continuous automatically igniting in start or flame-out back, fire combustion back firing circuit is deactivated immediately, needn't establish flame-out protection device again, goes back finite quantity during igniting and opens gas and time-limit attachment, prevents gas leakage, also can save energy;

3, the operator can recognize the ruuning situation of water heater by indicating member at one's side;

4, finish using, needn't close gas earlier and close water again, lay a finger on the shutdown button gently, water heater closes water after just closing gas earlier automatically, can also emit music;

5, when Guan Shui suspend to use (as smearing soap), it can suitably be lowered the temperature automatically, when boiling water uses again, needn't worry and the phenomenon that high-temperature water is hurted sb.'s feelings can occur;

6, it can also close gas check valve, water valve, the shutdown of cutting off the electricity supply again automatically when the user forgets pass gas or shutdown;

7, it does not increase auxiliary ignition device, can make ignitor away from flame not by vehement burning or high-temperature baking;

8, causing that because of various situations when overtemperature occurring, it can be regulated automatically, and water temperature is got back in the normal range (NR);

9, when hydraulic pressure transfinites, it also can be regulated automatically, and the interior hydraulic pressure weighing apparatus of machine is fixed in the normal range (NR), so can but can surpass the unlikely damage of working under the higher hydraulic pressure of normal hydraulic pressure with the overall withstand voltage design of water heater in normal operating range;

10, the user manipulates water heater in any case and deflagration phenomenon can not take place yet produces dangerous;

11, it can also select definite value water temperature output hot water, and the user is any assigned temperature value in the highest temperature that room temperature allows to water heater as required, and output should be worth the water of water temperature automatically, had removed tediously long temperature adjustment work from;

12, it can emit surplus water in the machine automatically when finishing using, and can not causing freezes damages;

13, it can also adopt and regularly take a shower and select regularly bathing method work, can avoid old, weak, sick, drunkard and person incapable of disposing to use and cause dangerous and unhealthful phenomenon generation.

In centralized control unit (12), be provided with water route servo amplifier (Z7) and preset loop, gas circuit servo amplifier (Z8) and preset elements (Z6) thereof, electric ignition assembly (Z5), start-up burner work condition inspection circuit, main burner work condition inspection circuit, logic circuit, also have power supply start and stop assembly (Z2), supply voltage monitor component (Z3), buzzing news to ring assembly (Z4), overtemperture control assembly (Z9), constant temperature control circuit, music news sound assembly (Z1); Also be provided with shutdown time of implementation circuit, suspend wait for (or shower) time circuit, close earlier and close water delay circuit, electric ignition the longest perdurabgility of circuit, an air valve behind the gas and gradually drive delay circuit, shutdown command retention time circuit, Guan Shui and suspend cooling delay circuit, supply voltage supervisory circuit delay time circuit out of control, prior notice circuit.

They connect each other like this and work: in operating unit (13), startup (start) button, water temperature adjusting knob, water yield adjusting knob, the hot and cold water options button of water heater are set, also are provided with again IGNITION CONTROL button, stand-by period prolongation button (or being shower selection of time button).(1), when the hot and cold water options button is chosen in the cold water position, touching starts button, under centralized control unit control, water heater begins to carry out preparation routine: power supply start and stop assembly (Z2) starts, the power supply self-sustaining, supply voltage monitor component (Z3) begins supply voltage is detected, if supply voltage has been lower than the minimum (can set up) of the scope of application, the display device that supply voltage is low is bright, control by logic circuit, change over to and carry out passive shutdown programm: start shutdown time of implementation circuit trigger, the buzzing news are rung assembly (Z4) and are begun to ring, the warning display device is bright, the loop of presetting of Water flow adjusting valve (2) is disconnected, promptly export to an input zero level of water route servo amplifier (Z7), water route servo amplifier (Z7) checks by voltage comparator whether servomotor (20) has got back to zero-bit immediately, it is the rest position of water regulating valve (2), as do not get back to zero-bit, it is non-vanishing that then the aperture detector (23) that is synchronized with the movement with the valve core of valve (2) outputs to the voltage of another input of servo amplifier (Z7), voltage comparator outputs to the voltage of servomotor (20) for negative, (annotate: (Z7) of indication, (Z8) voltage comparator in is exported to magnitude of voltage positive and negative of servomotor, arrange at the motor traffic direction, here about motor operation that makes surely, drive valve to the voltage of the direction motion of opening for just, otherwise, making valve is negative to the voltage of the position motion of closing, and the voltage that motor is stopped operating is zero.) make servomotor (20) counter-rotating, drive valve (2) by deceleration device (21) and get back to rest position, at this moment aperture detector (23) has been exported zero level, and voltage comparator output also is zero, and servomotor (20) stops operating.When shutdown time of implementation circuit delay finished, all displays spare all extinguished, and buzzer stops to ring, and power supply is promptly cut off by power supply start and stop assembly (Z2).If this water heater is to select for use battery in power supply, illustrate that battery should change or loose contact with old; If what adopt is that electric main is powered through voltage-stabilized power supply, illustrate that then power supply has fault, should check.

According to the drooping characteristic of battery, i.e. the energy of battery storage is sufficient more, and its internal resistance is more little, and under the constant load electric current, it is also long more to make terminal voltage drop to time of certain value.The utility model is provided with supply voltage supervisory circuit time-delay (t8) circuit out of control.During start, not low as supply voltage, then servo-electric chance rotation, be this moment in the water heater working than high current load, supply voltage supervisory circuit (Z3) is to the fade-out continuous detecting of supply voltage, as (t8) in the time voltage be lower than setting value, illustrate that then battery can not undertake the energy resource supply of this use, have only the battery of replacing to use, so shutdown time of implementation circuit is activated trigger, machine shuts down after carrying out passive shutdown programm again; If (t8) in the time voltage be not lower than setting value, illustrate that then the energy storage of battery can undertake the power supply task of this use at least, when (t8) finishing, the supply voltage supervisory circuit just only keeps monitoring function, its control ability with regard to split except, promptly in use monitor the supply voltage situation always, as be lower than setting value, the display device that its supply voltage is low is bright, but machine can not carried out shutdown programm yet, but continue to carry out service routine, just notify the user with display device, the energy content of battery is few.

If at (t8) in the time, supply voltage is not lower than setting value, and the shutdown button does not send shutdown command yet, control by logic circuit, the work display device is bright, suspending stand-by period (t2) circuit is activated, trigger, simultaneously, the water route is preset the loop and is switched on, and exports the input of a basic Chu voltage to servo amplifier, because at this moment aperture detector (23) is output as zero, so the comparator in the servo amplifier (Z7) just promptly is being output as, servomotor (20) just changes, and it is stand-by to move to the complete shut-down position by deceleration device (21) drive valve (2) from rest position, so far, preparation routine is finished, and water heater is in the wait user mode of using cold water.The use location of so-called water valve (2), the complete shut-down position and (the putting Yu Shui) position of stopping using, be in Water flow adjusting valve of the present utility model (2), three positions have been designed, three passages are arranged, inlet opening, apopore and put surplus water hole, water receiving source, inlet opening (1) on valve body, apopore connects water heater inner conduit (1a), puts surplus water hole and receives outside the water heater.First position is, when valve core moves, the inlet opening on the valve body communicated with apopore, and put surplus water hole and be closed this moment, and the valve core motion changes the area that the inlet opening communicates with apopore, promptly changes the aperture of valve, and this position is called the use location; When inlet opening, apopore with put surplus water hole three when all obstructed, be called the complete shut-down position; When the inlet opening is sealed by valve core, apopore with put surplus water hole when communicating, claim rest position, claim that also putting surplus water level puts.

For safety and energy-conservation, the utility model also is provided with the stand-by period, and the instant heating hydrophone is in the maximum duration of waiting for user mode, when this section period finishes, if user not boiling water uses, the startup that is triggered of prior notice circuit, buzzing news ring assembly rings, and at this moment uses as boiling water, then buzzing is rung and is stopped, the stand-by period delay circuit is by locking, and water heater enters user mode immediately, carries out the cold water service routine; If when buzzing is rung, the user also needs to wait for, prolongs button as long as lay a finger on the stand-by period gently, and water heater prolongs a stand-by period (t2) again, is in the wait user mode; After a period of time, user's boiling water not yet uses if buzzing news Chinese percussion instrument is rung, and when the prior notice circuit delay finished, shutdown time of implementation circuit was activated, and water heater changes over to carry out and shuts down after passive shutdown programm closes valve.If boiling water uses in wait state, one boiling water, centralized control unit begins to carry out the cold water service routine, pressure controller detects hydraulic pressure, when being lower than the minimum setting value of normal use as hydraulic pressure, the stand-by period delay circuit can be by locking, and when treating the time that (t2) finishes, water heater changes passive shutdown programm again over to; Not low as hydraulic pressure, behind the boiling water, the switch element of hydraulic controller is immediately with stand-by period delay circuit locking, the presetting potential device in loop is preset in adjusting, drive the servomotor running by servo amplifier (Z7), drive valve (2) motion by deceleration device (21) again, get final product the size of regulating pondage.(as smearing soap etc.) only need turn electric position down when needing to suspend in the use, and water valve (2) is promptly got back to the complete shut-down position, suspends stand-by period (t2) circuit and is activated trigger again, and water heater is got back to the wait user mode again.

When re-using, transfer big presetting potential device, water heater is carried out the cold water usage degree again and is benefited from for the user.In use, exceed setting scope of application peak as hydraulic pressure, the overpressure means of pressure controller is promptly exported negative-feedback signal, counter-rotating turns down valve (2) through servo amplifier (Z7) drive motor (20), as the hydraulic pressure increase that continues, valve also can continue to turn down the hydraulic pressure that makes in the water heater can not surpass the normal range value of setting all the time.Otherwise when hydraulic pressure reduced, pressure controller can be exported positive feedback signal again, valve is left greatly, that is to say that when water source hydraulic pressure superpressure, hydraulic pressure in the water heater weighs substantially through pressure controller adjustment meeting and can not exceed in the normal hydraulic pressure scope of application that fixes on setting.

When finishing using, need shutdown, 1, can turn the presetting potential device down, water valve is got back to the complete shut-down position, and water heater promptly is in wait state, if at this moment do not remake other operation, when stand-by period and prior notice time finish, it can change over to automatically carries out passive shutdown programm, makes water valve get back to rest position and emits surplus water in the machine, the shutdown of cutting off the electricity supply automatically; 2, for energy-conservation, also down water valve can turned, after making water heater get back to wait state, bump the button that shuts down again, water heater is carried out initiatively shutdown programm immediately, and music news sound assemblies (Z1) start rings, and shutdown command retention time circuit and shutdown time of implementation circuit start simultaneously, except that buzzing news sound assemblies (Z4) are not rung, begin to carry out passive shutdown programm; 3, can also work as water heater is water valve (2) when being in the use location carrying out the cold water service routine, directly lay a finger on the shutdown button, and water heater is carried out initiatively shutdown programm shutdown immediately.

(2), when the hot and cold water options button places the hot water position, touching starts button, water heater begins to carry out preparation routine, power supply start and stop assembly (Z2) starts, the power supply self-sustaining, supply voltage monitor component (Z3) begins supply voltage is detected, if voltage has been lower than setting value, then the low display device of supply voltage is bright, and water heater changes over to carries out passive shutdown degree shutdown.If supply voltage is normal, suspend stand-by period (t2) circuit start, trigger, water heater enters the execution ignition procedure: the warning display device is bright, gas circuit preset elements (Z6) is switched on, an electric ignition the longest perdurabgility (t4) circuit start, trigger, (Z6) open circuit of limiting the quantity of in is activated, send the input of a basic voltage to gas circuit servo amplifier (Z8), at this moment, aperture detector (29) is converted to electric weight with the aperture position of valve (8) and delivers to (Z8) another input, through the voltage comparator of (Z8) relatively after, the output correspondent voltage, gas circuit servomotor (26) is rotated, drive air valve (8) by deceleration device (27) and move to the preset position of limiting the quantity of and opening, at this moment the output voltage of aperture detector (29) equates with (Z6) voltage, the terminal voltage that voltage comparator outputs to servomotor (26) is zero, so (26) stall, under the control of logic circuit, water valve (2) can not be opened, so hydraulic pressure relay (3) is failure to actuate, aqueous vapor interlock valve (9) also is in closed condition, main burner and source of the gas are obstructed, combustion gas is through air valve (8) inlet point ignition combustor (11), simultaneously, the buzzing news are rung assembly (Z4) and are rung, electric ignition assembly (Z5) produces continuous high-voltage pulse immediately and delivers to ignitor generation spark ignition, igniting condition indicator spare is glittering, if do not have firing point ignition combustor flame in the time at (t4), when (t4) finishing, under the control of logic circuit, transfer the negative program of igniting of carrying out to, preset elements (Z6) disconnects, the voltage of an input that promptly is input to servo amplifier (Z8) is by the basic voltage vanishing, comparator output negative voltage, make servomotor (26) counter-rotating, drive valve (8) by deceleration device (27) and get back to the closed position, electric ignition assembly (Z5) stops igniting simultaneously, igniting condition indicator spare extinguishes, buzzing assembly (Z4) is still rung, so far igniting is negated that program is finished, this situation explanation gas circuit has problem, or air pressure is too little, or stop the supple of gas or steam or other air valve (if any) is forgotten out etc., can close machine check, promptly bump the button that shuts down, machine just begins to carry out initiatively shutdown programm, also can light a fire again, promptly bump IGNITION CONTROL button again, the ignition procedure igniting after it repeats again to start shooting; Can also be no matter when the stand-by period (t2) finishes, can automatically perform passive shutdown programm shutdown.In time, if fix a breakdown, bump IGNITION CONTROL button again as long as touch at (t2), water heater begins to carry out the ignition procedure igniting again.Start-up burner is once lighting, start-up burner operating mode detector (18) is sent corresponding electric weight immediately and is given its supervisory circuit, the output of supervisory circuit makes electric ignition assembly (Z5) stop igniting, electric ignition condition indicator spare extinguishes, start-up burner condition indicator spare is bright, the warning display device extinguishes, and the work display device is bright, (Z4) stops to ring, (Z6) in limit the quantity of open circuit through air valve gradually open circuit carry out the transition to the air valve prewired circuit, at this moment ignition procedure is finished.Then, the water route is preset the loop and is switched on, and it is stand-by that water valve (2) promptly moves to the complete shut-down position from rest position, and so far, the hot water preparation routine is finished, and water heater is in the wait user mode of using hot water.If the stand-by period is oversize, when having surpassed the time-out stand-by period (t2), the prior notice circuit is triggered, the buzzing news are rung assembly (Z4) and are begun to ring, if still needing, the user requires to wait for again, as long as touching, the stand-by period prolongs button, water heater begins (t2) stand-by period time-delay again, (t2) in the time or prior notice (t9) in the time boiling water use, transferring the big yield adjusting knob is the water route servopotentiometer, water heater begins to carry out the hot water service routine, pressure controller begins hydraulic pressure is detected, very low as hydraulic pressure, hang down and to start (setting value when dispatching from the factory) to pressure controller, then when (t2) finishes, after buzzer is rung, water heater changes the passive shutdown programm of execution as a rule over to and shuts down, if hydraulic pressure is normal, behind the boiling water, switch element in the pressure controller (SY) is the time-delay of locking (t2) immediately, and hydraulic pressure relay (3) promotes aqueous vapor interlock valve (9) by pressure controller and opens, main burner is lighted immediately, its operating mode detector (19) is sent this signal into main burner work condition inspection circuit, and its condition indicator spare is bright, and hot water has just flowed out, regulate the water temperature adjusting knob, be presetting potential device in the preset elements (Z6), can change the aperture of air valve (8), thereby change the height of the size of main burner flame with the change water temperature.The regulating pondage adjusting knob is a water route presetting potential device, can change water valve (2) thus aperture change the size of discharge.

As because of (the big wind of certain reason, or source of the gas interrupts suddenly), make water heater flame-out, main burner and start-up burner operating mode detector are all sent into flame-out signal, make corresponding work condition inspection circuit operation, and its condition indicator spare all extinguishes, water heater is carried out the ignition procedure igniting immediately, after water valve is treated cools down, when promptly pass water delay (t3) time finishes behind the gas of elder generation pass, also unignited as igniting, water valve (2) cuts out immediately.If in an electric ignition the longest perdurabgility (t4), also do not fire, promptly transfer the negative program of igniting of carrying out to; If light, except that finishing ignition procedure, water heater promptly enters carries out the hot water service routine, and water valve, air valve are all got back to just now preset position and flowed out the hot water that has mixed up and come.

When needs suspend use, turn water yield adjusting knob down, water valve (2) moves to the complete shut-down position from preset position, hydraulic pressure and discharge in the water heater machine all reduce gradually, when hydraulic pressure is reduced to certain pressure, hydraulic pressure relay (3) discharges, by hydraulic controller aqueous vapor interlock valve (9) cuts out, main burner flame extinguishes immediately, and its condition indicator spare also extinguishes, and main burner work condition inspection circuit starts pass water immediately and suspends cooling time-delay (t7) circuit, output a control signal to the input of water route servo amplifier (Z7), make it be output as zero, servomotor (20) stall, thereby water valve stop motion.At this moment water valve (2) is not also got back to the complete shut-down position, still keeps certain aperture, makes current continue to flow, thereby makes heat exchanger (4) cooling in the water heater.When (t7) time-delay finishes, Guan Shui suspends the control signal of cooling time-delay (t7) circuit and removes, servomotor begins counter-rotating again, drive water valve and move to the complete shut-down position, at this moment the electric weight sent of aperture detector (23) equates with the basic voltage that the loop is preset in the water route, motor (20) stall, simultaneously, the switch element of complete shut-down position detector is also sent the command signal that makes motor (20) stall, avoid motor (20) not stop,, suspend stand-by period (t2) circuit and be activated trigger again so water valve (2) promptly is parked in the complete shut-down position reliably, so far, water heater is got back to the wait user mode again.When re-using, transfer the big yield adjusting knob, water heater is carried out the hot water service routine again, and the bather brings into use hot water again.

In use very big as air pressure, hydraulic pressure is very little, when the user does not turn the water temperature adjusting knob again down, superheating phenomenon (promptly surpassing 65 ℃ of values stipulating among the GB GB6932-86) takes place in water temperature easily, meet this situation, the set over-temperature sensor (5a) of the utility model is sent the overtemperature signal into overtemperture control assembly (Z9), (Z9) export the input of negative-feedback signal immediately to gas circuit servo amplifier (Z8), make its voltage that outputs to servomotor (26) for negative, drive motor (26) drives air valve (8) and reduces aperture, if air pressure continues to rise, water temperature can rise again, the corresponding increase of negative-feedback signal makes corresponding the reducing of aperture of valve, makes water temperature can not surpass the peak of the normal use water temperature of setting all the time.

When finishing using, can adopt the variety of way shutdown, following surface analysis is once when using hot water, close the reaction that the water yield, water temperature adjusting knob or touching shutdown button cause: when 1. using, closing water yield adjusting knob promptly turns the water route down and presets button to zero position, water heater is got back to hot water and is waited for user mode after carrying out pass water time-out service routine, regulate the water temperature adjusting knob again and do not have influence.If no longer touch other operating knob, to delay time when finishing at (t2) with (t9), water heater is carried out passive shutdown programm shutdown.If when waiting for user mode, lay a finger on the shutdown button again, water heater changes over to immediately carries out initiatively shutdown programm; Shutdown command retention time circuit and shutdown time of implementation circuit start simultaneously, the work display device extinguishes, the warning indicator lamp is bright, (Z1) music of ringing, start simultaneously earlier and close the action of water delay circuit behind the gas of pass, gas circuit preset elements (Z6) disconnects, make air valve (8) get back to the closed position, main burner and start-up burner flame all extinguish, and its corresponding condition indicator spare also extinguishes, and at this moment water valve (2) is still opened, current are taken away the waste heat of heat exchanger, after treating its cooling, when closing the time-delay end of water behind the gas of pass earlier, the water route is preset the loop and is disconnected, water valve (2) is promptly got back to rest position (the complete shut-down position detector has not had effect) by the use location by the complete shut-down position, emit surplus water in the machine, when the shutdown time of implementation finished, driving power start and stop assembly (Z2) was cut off the electricity supply, at this moment all display devices all extinguish, the news Chinese percussion instrument stops ringing, and water heater initiatively shutdown programm is finished, and water heater is in dead status; 2. close earlier gas check valve, promptly turn the water temperature adjusting knob down to zero, air valve (8) is got back to certain aperture, and main burner still keeps very little flame, and water temperature reduces, shutoff valve more at this moment, and water heater is got back to hot water again and is waited for user mode, with 1. identical; 3. directly touch the shutdown button in use, water heater changes over to immediately to carry out initiatively from user mode and shuts down behind the shutdown programm.The third shutdown mode is the simplest, and the most energy-conservation.

Regularly take a shower (or water supply): noted earlier when entering (cold water or hot water) user mode at water heater, the switch element in the said pressure controller (SY) can be with the time-delay locking of stand-by period (t2) circuit; When the stand-by period (t2) finished, the touching stand-by period prolonged button, and the stand-by period can continue (t2) time again.If switch element in the pressure controller (SY) and stand-by period prolongation button are all removed not, the time delay of proper extension (t2), then (t2) time becomes the control time of the whole process that finishes from the shower of starting shooting, and at this moment water heater just becomes and regularly takes a shower or the water heater of Timing water supply.This uses for the elderly, valetudinarian, drunkard and person incapable of disposing, can reduce accident rate.

If on the basis of regularly taking a shower, change into (t2) delay time adjustable, and will adjust on the panel that element is arranged on operating unit (13), make the operator can freely set up delay time, this water heater just becomes regularly the take a shower water heater of (or Timing water supply) of adjustable time, to adapt to the needs that each human needs and various occasion are used.

Constant temperature is taken a shower (or water supply): during described in front use hot water, its method of regulating water temperature is called temperature-sensitive and regulates method, and promptly in user mode, the regulating pondage adjusting knob can change water yield size, regulates the water temperature adjusting knob, can change the height of water temperature.But the height of this water temperature does not have concrete value, just regulates with people's sensation.The shortcoming of this method is: after each start, adjustment is blindly, will be through regulating repeatedly, repeatedly know from experience and just can be transferred to the suitable water temperature and the water yield, and water yield of every change, or because of hydraulic pressure, air pressure fluctuation, all can influence water temperature, must readjust, hydraulic pressure, air pressure fluctuation are big, also scald the people easily.Both lost time, wasted energy again.

The utility model can adopt constant temperature to regulate shower (or water supply) method: concrete temperature indicated value is arranged on the water temperature adjusting knob in operating unit (13), when you choose certain temperature value, after the start, by all means the water yield is transferred to required size, water temperature just can be stabilized on your the selected temperature value, when air pressure, hydraulic pressure (within the specific limits) fluctuation, the Water outlet water temperature is stabilized on the set point value basically, has overcome the disadvantage of temperature-sensitive adjusting method.

This purpose of the present utility model is achieved in that on the hot-water line of water heater heat exchanger (4) back or in the pipe, constant temperature sensor (5b) is housed, this sensor is received in the constant temperature control circuit that gas circuit servo amplifier (Z8) input sets up, an input of (Z8) is received in the output of constant temperature control circuit, and (Z8) another input is received the output of preset elements (Z6).When adjusting water temperature adjusting knob is indicated to certain temperature value, (Z6) output correspondent voltage value (VZ6), sensor (5b) is experienced the temperature of hot water outlet, be converted into the electric weight in the constant temperature control circuit, the constant temperature control circuit is then exported and present water temperature correspondent voltage value (VD), these two magnitudes of voltage are delivered to two inputs of (Z8) respectively, (Z8) after the voltage comparator in compares, the voltage of exporting corresponding polarity drives servomotor (26) forward or reverse, drive throughput control valve (8) by deceleration device (27) and do motion accordingly, to change the aperture of valve (8), thereby regulate the size of gas flow, reach the purpose of regulating the main burner flame size, promptly change the height of water temperature, when the water temperature of experiencing up to cooling-water temperature sensor (5b) is consistent with the water temperature of setting, (5b) magnitude of voltage of constant temperature control circuit output is equated with the magnitude of voltage of (Z6) output, when being VD=VZ6, then (Z8) is output as zero, motor (26) shuts down, and valve (8) then keeps certain aperture.When t ° of water temperature change Δ, (as regulating pondage or hydraulic pressure, air pressure fluctuation etc.) output of constant temperature control circuit also changes Δ V, because (Z6) output voltage does not change, still be (VZ6), so (Z8) promptly export Δ position of aperture change that the voltage drive motor of corresponding polarity drives valve (8), when the temperature of experiencing up to (5b) makes VD=VZ6, valve (8) keeps its aperture again, and the output hot water temperature is followed the tracks of basically on selected temperature value.But this function is starting start, and when water heater was carried out ignition procedure in the preparation routine, preset elements will be exported a basic voltage quantitatively opened for igniting air valve.And at this moment not there are flowing out, what constant temperature sensor (5b) was experienced is room temperature, and the voltage VD＜VZ6 of constant temperature control circuit output is just changeing motor (Z6), and the aperture of valve (8) increases.Owing to there is not hot water to flow out, (5b) pipe valve (8) aperture is not much, still keep room temperature, keep the state of VD＜VZ6, so motor (26) can just change always, valve (8) continues out greatly, when making motor carry detector (30) action motor is shut down, valve (8) has reached maximum position, does not promptly have the function that air valve is limited the quantity of and opened.In order to reach the function that air valve is limited the quantity of and opened, the utility model also is provided with the air valve unlatching tracking circuit of limiting the quantity of in the constant temperature control circuit, promptly in the start-up burner ignition process, limited the quantity of by air valve and to open tracking circuit work, after the flame ignition, sensor (5b) just comes into operation.

Air valve in the preset elements (Z6) is limited the quantity of and opened and the gradually effect of open circuit of air valve: the utility model is owing to be provided with anti-detonation measure, promptly when using hot water, before start-up burner is lighted, water valve is restricted, can not open, so the deflagration phenomenon can not take place to hold gas behind main burner gas leakage and the first boiling water time.But, in the process of using hot water, the instant heating hydrophone is in user mode, when air valve opening is big again, because of certain reason, cause water heater to stop working (comprising start-up burner) suddenly, close the startup of water delay circuit after closing gas earlier, water valve will wait until after the waste heat in the heat exchanger reduces and just cut out that so at this moment water valve keeps open-minded, aqueous vapor interlock valve is also opened, air-flow still flows out from main burner, though the electric ignition circuit is lighted a fire immediately, the combustion gas of Duoing when some are always arranged than normal the use is flowed out, and is easy to generate deflagration phenomenon once lighting a fire.In order to prevent the generation of this phenomenon, being provided with air valve limits the quantity of and opens and air valve open circuit gradually, in case it is flame-out, air valve turns back to the enable possition of limiting the quantity of immediately, even aqueous vapor interlock opening of valves, the air-flow that flows out from main burner also is less, once a gas valve be open gradually big, both prevented detonation, and also reduced air valve and opened suddenly that flame was not from there being the noise that causes to very big.

Limiting and protecting device when servomotor carry detector (24) and (30) also do not stop as motor contingency setover.

The utility model is because adopted servomotor to control the aperture of throughput control valve and Water flow adjusting valve, carry out logical operation and programme-control by centralized control unit, realized using light and numerous and diverse mode of operation that the shirtsleeve operation mode replaces prior art to require great effort very much; Be provided with various detections, controller and indicating member, the user can recognize the ruuning situation of water heater at any time, in case abnormal conditions occur, can in time notify the user, and make corresponding judgment and processing automatically by centralized control unit, ensured safety; Automatically controlled owing to having taked, so can realize prosecutor formula far away, give and use water heater that safety and operation easily are provided.The utility model can also constant temperature takes a shower (or water supply), regularly or take a shower when selecting (or water supply), the energy and time have been saved, reduced accident rate, in use, the operation of servomotor is short time and interruption, most times are in halted state, so the complete machine little power consumption is well suited for using powered battery.

Hot and cold water options button (K1) is in closing position among Fig. 3, and promptly (K1) is selected in the position of using hot water (HW), (C1) is power supply filter capacitor.Press startup (start) button (AN1), power supply start and stop assembly (Z2) starts, (J) adhesive, the power supply self-sustaining, the water heater open beginning is carried out preparation routine: at first supply voltage monitor component (Z3) is monitored supply voltage, if supply voltage (E+) has been lower than setting value, program forwards to carries out passive shutdown programm, (Z3) output (Q8) is 0 level, at this moment because effect (C26) no matter what level nor gate (HF1) exports, (P5) is 0, so nor gate (HF8) is output as 1, (HF1) output is 0, and NAND gate (YF1) output then is 1, and warning indicator lamp (D2) is bright, (R5) be its current-limiting resistance, (D3) turn-off.Because supply voltage suddenlys change to (E+) (never reaching unlatching) by zero,, (BG1) ended through (R128), (R127), to (C28) and (C4) charging.The water route is preset the loop and is disconnected, and the voltage comparator (IC1) in the servo amplifier (Z7) is identical with (IC2) output voltage, and motor (M1) both end voltage difference is zero, thus motor (20) promptly (M1) still rest on water valve (2) rest position.Because (HF1) output 0, phase inverter (F1) output (Q2)=1, (Z2) shutdown time of implementation (t1) the circuit trigger in, or the output (Q6)=1 of door (H2), (BG3) end, preset elements (Z6) disconnects, and the voltage comparator (IC3) in the servo amplifier (Z8), (IC4) also export identical voltage, motor both end voltage difference is zero, thus motor (26) promptly (M2) still rest on the position that air valve (8) is closed.And (Q2)=1 o'clock, nor gate (HF2) is output as 0, and at this moment (P1) point is 0, so or door (H1) output (Q3)=0, (Z4) ring; Because (HF1)=0 o'clock, NAND gate (YF2) is output as 1 again, and phase inverter (F12) is output as 0, so (Z5) do not produce the high-voltage pulse igniting.When the shutdown executive circuit time-delay (Z2) finishes, (J) discharge dump.

After pressing start button (AN1), (E+) is not low as supply voltage, and preparation routine begins again, (Z3) output (Q8)=1, (Q1)=0 then, when not pressing, (P1)=0, (C3) of stand-by period (t2) circuit is by (R2) charging at shutdown button (AN2), (Q7)=0, (P2)=0, so nor gate (HF1) is output as 1, (Q2)=0, (Z2) (t1) in do not delayed time by locking, because start-up burner do not fire fire, its operating mode detector (18) presents high resistant, and is low level at phase inverter (F2) input after (R15) dividing potential drop, so (Q4)=1, (C5) (P3)=1, (HF3) is output as 0 by (R17) charging in an electric ignition the longest perdurabgility (t4) circuit, (Q6)=0, (BG3) conducting is a current-limiting resistance (R19), (Z6) is switched on.In addition, (YF2) be output as 0, (F12) be output as 1, promptly (Z6) (4) pin is a high level, (Z6) in by (BG18) (BG19) open circuit of limiting the quantity of (R76) formed of Zener diode (D15) resistance (R37) start, promptly by current-limiting resistance (R76) (R77), make (BG19) conducting, (BG5) end, referring to Fig. 7.At this moment the output voltage of (2) pin is the voltage Vz+VcEs(BG19 of stable pipe (D15))-VBE(BG18), the height of its voltage depends on the size of Vz, and Vz is big, output voltage height (Z6), valve (8) aperture is big, otherwise the aperture of valve (8) is then little.(2) this voltage of pin output is delivered to an input (r) of servo amplifier (Z8), the i.e. end of oppisite phase of (IC3) and (IC4) in-phase end, because servomotor (M2) drives air valve (8) by deceleration device (27) and rests on the closed position, its aperture detector (29) is that potentiometer (W5) cursor slide is input to the other end (i) of (Z8), promptly the voltage of the in-phase end of (IC3) and end of oppisite phase (IC4) approaches zero, at this moment the voltage of (IC3) end of oppisite phase is higher than the in-phase end voltage output end and is 0, (IC4) in-phase end voltage is higher than end of oppisite phase, be output as (E+), so (M2) just change, valve (8) is opened, (W5) cursor slide also accompany movement arrives corresponding position, the current potential that is input to (Z8) is improved gradually, the end of oppisite phase voltage that arrives (IC4) is greater than in-phase end, (IC4) export by (E+) to 0, at this moment the end of oppisite phase voltage of (IC3) is also greater than in-phase end, output also is 0, so motor (M2) both end voltage difference also is 0, (M2) stop operating, valve (8) keeps certain aperture, and combustion gas enters into start-up burner.Because (Q4)=1, (HF2) be output as 0, at this moment, (P1)=0, so (Q3)=0, (Z4) ring, its (4) pin output low frequency pulse signal, and (2) pin level (Z5) also is 1, delivers to ignitor (17) generation electric spark so (Z5) produce high tension ignition pulse, and start-up burner (11) is lighted a fire.At this moment, (Q4)=1, phase inverter (F3) output still is 0, (YF1) output (Q9)=1, so (M1) still do not rotate, valve (2) is still in rest position.

If (t4) in the time start-up burner also unignited, igniting is negated that program promptly begins, along with (R17) charging to (C5), (P3) current potential reduces gradually, low to making (HF3) upset, (Q6)=1, (BG3) end, (Z6) disconnect, at this moment Vr=(R29+R30)/(R124+R29+R30) (E+) approaches zero in (Z8), so in-phase end voltage (IC3) is greater than end of oppisite phase voltage output (E+), (IC4) in-phase end voltage is lower=(R30(E+))/(R124+R29+R30), its end of oppisite phase voltage is output as 0 greater than in-phase end, (M2) counter-rotating, as (R30(E+))/(R124+R29+R30)＜Vi＜((R29+R30) (E+))/(R124+R29+R30) time, (IC3) output 0, (IC4) output also is 0, (M2) stop, at this moment air valve is in closed condition.(R26) (R27) (R28) is isolation resistance (R29).Carry detector (30) i.e. is (XW3) and (XW4), and because of certain reason (as the potentiometer damage etc.) stopping time not, the switch element (XW3) of corresponding carry detector or (XW4) action shut down (M2) at motor (M2).For example work as Vi＞Vr, and do not change with the motor rotation, then the in-phase end voltage of (IC3) is greater than end of oppisite phase, output (E+), (IC4) end of oppisite phase voltage exports 0 greater than in-phase end, motor (M2) counter-rotating, after valve (8) cuts out, motor continues counter-rotating, and at this moment (XW4) closure makes (IC3) output become 0 by (E+), (M2) the both end voltage difference also is 0, thereby (M2) stopped operating.Same (M2) just change when Vr＞Vi, arrive valve (8) standard-sized sheet and still do not stop when logical, then (XW3) closure is exported (IC3), (IC4) and is (E+), and (M2) the both end voltage difference is 0, makes (M2) stall.(P3) low level also makes (YF2) to be output as 1, (F12) is output as 0, makes (Z5) stop igniting, and at this moment (Z4) still rings.If this situation continues always, charging along with (C3) in (t2) circuit, (R2) current potential on reduces gradually, when dropping to certain value, and (F5) upset, (Q7)=1, in advance (C27) of (t9) announcing circuit by (R45) charging, (P2) current potential raises, (HF1) is output as 1 when (HF1) overturn, situation when at this moment low with supply voltage is consistent, makes shutdown and handles.

If in (t2) igniting again in the time, pressing IGNITION CONTROL button (AN4), (C5) discharges immediately again, (AN4) after the release, (C5) again by (R17) charging, ignition procedure begins again, (BG1) conducting at this moment, and valve (8) is quantitatively opened, (Z5) begin igniting, the ignition process when repeating to start shooting again.After start-up burner (11) flame ignition, its operating mode detector (18) becomes low-resistance, after (R15) composition divider dividing potential drop, voltage comparator circuit (being served as by reverser) (F2) is overturn, (Q4)=0, (D4) is bright for light emitting diode, (R16) be current-limiting resistance, at this moment (P3)=0, institute is so that (F12) be output as 0, (Z6) open circuit of limiting the quantity of in disconnects, be transformed into by (BG18), (BG5), (BG6), (R37), (R77), (R46), (RY) and the prewired circuit formed of potentiometer (W4), in its conversion, by electric capacity (C9), resistance (R46), (R72) the gradually open circuit transition of air valve that cooperates prewired circuit to form, (BG5) by the time, (C9) by (R46) emitter junction discharge off (R72) and (BG6).When (4) of (Z6) pin is 0, (BG19) end, (BG5) conducting, (C9) by (R72) (BG6) charging of (R37), (BG5), adjust current-limiting resistance (R72) make begin charging constantly the conducting degree of (BG6) output voltage of (BG18) emitter stage is approximated limit the quantity of voltage when opening, charging along with (C9), (BG6) the conducting degree i.e. output voltage of (Z6) transfers to gradually by potentiometer (W4) and determining, (C9) be full of after, (C9) (R72) promptly ineffective, reached the effect that air valve is gradually opened.(RY) be the adjustment resistance of basic voltage value, (RY) value is selected in when closing gas, be that the cursor slide of presetting potential device (W4) is when sliding into (W4) with the end that (RY) joins, (Z6) minimum voltage that can export of (2) pin, the aperture that valve (8) is opened is maintained the burning of start-up burner.After the combustion of start-up burner (11) flame, (Q4)=0, (F3) output (j)=1, (Q9)=0, (D1) is bright for relay indicating light, (R4) be current-limiting resistance, (BG1) conducting, loop (W1) is preset in the water route, (W2), (R8) be switched on, (R8) be selected in when (W2) cursor slide is transferred to (W2) with the end that (R8) joins, (W2) the cursor slide voltage Vv that is input to (Z7) make water route servomotor (20) promptly (M1) just in time forward the complete shut-down position by deceleration device (21) drive valve (2) to from rest position, at this moment, aperture detector (24) i.e. (W3) is input to the voltage Vu=Vv of (Z7), promptly the end of oppisite phase voltage of (IC1) is greater than in-phase end voltage, and defeated is 0, and end of oppisite phase voltage (IC2) is also greater than in-phase end voltage, output also is 0, so motor (M1) stops operating.Because (Q4)=(Q2)=(Q7)=0, (HF2) be output as 1, (Q3)=1, (Z4) stop to ring, preparation routine promptly is finished, and at this moment water heater is in hot water wait user mode.

Transfer big water valve (2), be about to potentiometer (W2) to adjusted, service routine just begins to carry out, Vv＞Vu, (M1) just change, water valve (2) enters the use location, current promote hydraulic pressure relay (3), make its moving axis (33) protruding (as Fig. 1), promote the tooth bar (34) in the pressure controller (16), drive seat (38) by fixed force spring (36) and move (as Figure 21) along the direction of arrow, continue to promote the moving axis (32) of aqueous vapor interlock valve (9), aqueous vapor interlock valve (9) is opened, combustion gas is at this moment flowed out by main burner (10), start-up burner flame ignites main burner immediately to heat exchanger (4) heating, and hot water has just flowed out.Main burner operating mode detector (19) becomes low resistive state from high-impedance state, after (R18) dividing potential drop, makes reverser (F4) upset, Q5=0, and (D5) is bright for the main burner work condition indication lamp, (R20) is its current-limiting resistance.Seat in pressure controller is during translation, (38a) of seat partly makes switch element (SY) (the being reed switch) closure that is fixed on the water heater fuselage here, (SY) is attempted by (C3) two ends of (t2) circuit, so (t2) delay circuit is not delayed time, (Q7) weighing apparatus is low level.The elastic force of fixed force spring (36) can not be compressed when being located at normal hydraulic pressure, and the initial pressure when it can be compressed is regulated selected by pressure adjustment screw (37).So when normal hydraulic pressure, when promptly hydraulic pressure surpassed the setting pressure of (37) setting up, spring (36) can not be compressed, therefore, tooth bar (34) does not have relative displacement with seat (38), and gear also maintains static.During normal pressure, (38e) portion of seat (38) all is pressed into the moving axis (32) of aqueous vapor interlock valve (9) on the valve body that withstands on interlock valve (9) then, can not move forward again, if hydraulic pressure continues to increase, the moving axis (33) that withstands on the hydraulic pressure relay of the end (34a) of pressure controller tooth bar (34) locating (3) is again to overhanging, by tooth bar (34) compression spring (36), (34) i.e., present (38) middle translation, at this moment gear (35) rotates, the rotating shaft that drives rotary shaft potentiometer (W1) by the hollow shaft (35a) that is fixed together with gear (34) in the support (38b) that is contained in seat (38) is rotated, the resistance value at (e-f) two ends of potentiometer is increased, (e-f) two terminate among Fig. 3 the water route and preset in the loop.Radially being fixed with pin sheet (39) in the rotating shaft (40) of potentiometer (W1) can swing in the cotter way of hollow shaft (35a), adjustment screw (35b) can be regulated the size in swing gap, can regulate the hysteresis difference of pressure controller, to prevent vibration.(38c) be baffle plate, fixing by screw (38d).

Pressure controller can have multiple structure, and Figure 22 shows another kind of structure.The moving axis (33) of hydraulic pressure relay (3) withstands on the length adjustment screw (139) of axle (134), axle (134) is by fixed force spring (136), plug (141) and pressure adjustment screw (137), the pressure of (33) is passed to seat (138), partly withstand the moving axis (32) of aqueous vapor interlock valve (9) again by (138e) of seat (138).(138a) of present (138) locates to be equipped with magnet piece (99), and along being fixed with tongue tube (142) on the fuselage of water heater on the direction of advance of arrow, the two ends of (142) also are connected in (C3) two ends.When hydraulic pressure just often, moving axis (33) impeller-hub (134) of hydraulic pressure relay (3), can not compress when at this moment pressure adjustment screw (137) is adjusted in normal hydraulic pressure with the pressure of fixed force spring (136), so make seat (138) along direction of arrow translation by (137), magnet piece (99) makes tongue tube (142) closure, be increased to as hydraulic pressure and exceed normal range (NR), when making spring (136) compression, groove (140) on the axle (134) is promptly stirred linear sliding potentiometer (W1) handle, makes resistance value increase between (e-f).The width of groove (140) (except that the potentiometer handle) is the hysteresis difference.

When using hot water, regulate the size that (W2) can change the water yield, (W4) that regulate in (Z6) can change the size of throughput, thereby changes the size of main burner (10) flame, to change the height of water temperature.When hydraulic pressure surpassed normal value, (e-f) two ends resistance of potentiometer (W1) increased, and hydraulic pressure surpasses many more, and the resistance increment is also many more.(W1) increase of resistance makes the also corresponding reduction of voltage on potentiometer (W2) cursor slide, and promptly Vv reduces, (M1) counter-rotating, and the aperture of water valve (2) reduces, and hydraulic pressure promptly reduces, and has reached the purpose of control hydraulic pressure.If regulate (W4) be transferred to air valve (8) aperture very big or air pressure very big originally, (W2) be transferred to make water valve (2) aperture very little or hydraulic pressure is very little originally, at this moment superheating phenomenon takes place in water temperature easily.As it is overheated that water temperature takes place, over-temperature sensor (5a) resistance will diminish, form (as Fig. 3) after the divider dividing potential drop with (R22) in the overtemperture control assembly (Z9), voltage comparator circuit (serving as with Schmidt trigger here) (F6) is overturn, adjustment (R22) resistance can change the temperature value when making (F6) upset, (F6) output level changes to 0 by 1, bias current is provided for (BG4) by (R23), by (BG4), (5a), (R22), (R23), (R24), (R25) reach (W5) formation amplifier, it is voltage-regulating circuit, (5a) as the emitter degeneration element, temperature is high more, (5a) resistance is more little, and (n) point voltage is high more, plays the pressure regulation effect.(n) point voltage Vn is high more, and Vi is also high more, and Vr does not become, and makes (M2) counter-rotating, and valve (8) aperture reduces, and throughput reduces, and main burner flame reduces, and water temperature is reduced, and gets back in the normal range (NR).Water temperature reduces, and (5a) resistance increases, and Vn also reduces, and valve leaves again greatly, and water temperature is gone up again, and water temperature can be stabilized near the peak in the normal range (NR) like this, utilizes the hysteretic characteristic of Schmidt trigger, and system can not vibrated.When water temperature was in normal range (NR), (5a) resistance was bigger, and is low with (R22) voltage after partial, can not make (F6) upset, (F6) be output as 1, (BG4) end, at this moment (BG4) plays buffer action, makes the overtemperture control circuit not have influence to (Z8) work when normal water temperature.

According to above design philosophy, the physical circuit of overtemperture control assembly (Z9) also can have various ways, and Fig. 6 has provided two kinds of overtemperture control circuit in addition.In Fig. 6 a, (IC16) make voltage comparator with switch integrated circuit TWH8778, (R84) be thermistor (being over-temperature sensor 5a), form divider with resistance (R85), work as branch pressure voltage, when promptly (q) point voltage Vq is greater than (TWH8778) control utmost point (5) pin cut-in voltage VENT, (2) pin is output as 1, (2) pin was 0 when branch pressure voltage was lower than VENT, when normal water temperature, Vq=(R85)/(R84+R85) (E+)＜VENT, (BG26), (BG4) all do not work, (D18) play buffer action.When water temperature raises, during overrun, (R84) resistance reduces, Vq 〉=VENT, make (2) pin output of TWH8778 be about (E+), (BG26), (BG4) all is in the amplification region, adjust (R118), (R131) and (R120) can select (BG26) (BG4) suitable operating point, (n) output one positive voltage, water temperature is high more, and (R84) resistance is more little, (BG26) Ic(collector current) big more, (BG4) Ic is more little, and (n) the some current potential is high more, a kind of effect of circuit before having played.Adjust the hysteretic characteristic that (R86) can change this circuit.In Fig. 6 b, over-temperature sensor (5a) serves as with transistor (BG27), (R133) forms divider by (R132), and (BG27) is arranged on the amplification region, regulate the temperature coefficient that (R134) can change (BG27), export temperature variant voltage by (BG27) colelctor electrode.When temperature just often, (BG27) the colelctor electrode output voltage is higher than the turnover voltage (VT) of Schmidt trigger (F6), (F6) output 0 level, isolating diode (D18) turn-offs.When temperature surpassed normal value, (BG27) collector voltage was lower than (VT), (F6) upset, be output as 1, at this moment field-effect transistor (BG25) plays variable-resistance effect, after (R123) dividing potential drop, by (D18) output positive voltage (Vn).(R122) be (BG25) input resistance, adjust (R123) and can change the Vn size.Temperature is high more, and (BG27) collector potential is low more, and the resistance that (BG25) is presented by (R122) is big more, thereby (Vn) high more.When (Z9) in replacing Fig. 3, (l) meet (Ek+), (m) connect (K), (n) connect (n) point.

In use need to close water and suspend use (as smearing soap etc.), water yield adjusting knob is turned down, promptly (W2) cursor slide links to each other with an end of (R8), and at this moment Vu＞Vv in (Z7) (IC1) exports (E+) and (IC2) exports 0, (M1) counter-rotating.Driving valve (2) moves to the closed position, the water yield reduces gradually, the also corresponding reduction of hydraulic pressure in the water heater, when hanging down to certain value, hydraulic pressure relay (3) discharges, the i.e. moving axis of (3) (33) withdrawal, pressure controller is followed along arrow (Figure 21,22) move in the other direction, (SY) disconnect, the moving axis (32) of aqueous vapor interlock valve (9) stretches out, valve (9) cuts out, main burner (10) source of the gas is cut off, fray-out of flame, its operating mode detector (19) (Fig. 3) resistance becomes big, (F4) upset, (Q5) change to 1 by 0, by transistor (BG2), resistance (R9), (R21), (R126), (R44), capacitor (C6), the pass water of forming with door (Y2) and complete shut-down position detector (ZT) suspends cooling time-delay (t7) circuit operation, (E+) charge to (C6) by (R44), (P6)=1, at this moment still burning because of start-up burner (11) flame, (j)=1, so with door (Y2) output 1 level, (R21) make (BG2) saturation conduction by current-limiting resistance (R126), in-phase end level (IC1) is approximate for 0(immediately), make (IC1) output change to 0 by (E+), (M1) stall, valve (2) stop motion, at this moment valve (2) also keeps certain aperture, current continue to flow, and make heat exchanger (4) cooling.Along with (C6) charging, (P6) the some current potential reduces gradually, when hanging down the changing voltage (VTR) that arrives gate circuit, (Y2) output level changes to 0 by 1, (BG2) end, (R9) be following biasing resistance, (IC1) in-phase end voltage returns to (Vu) again, (M1) continue counter-rotating, during to (Vu=Vv), at this moment (IC1) in-phase end current potential exports 0 less than end of oppisite phase, (IC2) still like this, (M1) shut down, this position determines that by (R8) its value is selected in valve (2) and just in time is parked on the complete shut-down position.If for a certain reason, (M1) also do not stop when making valve (2) to the complete shut-down position, set up complete shut-down position detector (ZT) in the complete shut-down position, make (ZT) closure when valve just in time arrives the complete shut-down position, (E+) make (BG2) conducting through (BG1), (ZT), (R21), force (IC1) (IC2) to export 0, (M1) stall, water heater promptly is in the wait user mode.Because of (SY) disconnects, stand-by period (t2) circuit start trigger.When if (t2) time finishes also not again boiling water use, it can change passive shutdown programm over to, buzzing rings in advance, also uses then valve-closing shutdown (preceding state).

When in the stand-by period (t2) or (t2) finishing back prior notice (t9) and re-using in the time, adjust (W2), make Vv＞Vu, water valve is opened again, gets back to aforesaid user mode and uses.As in use or etc. bide one's time flame-out, (Q4) (Q5) change to 1 by 0, (D4) (D5) extinguishes, (Q4)=1, (P3)=1, make (F12) be output as 1, the open circuit of limiting the quantity of in (Z6) starts again, and air valve turns back to the position of limiting the quantity of immediately, (Q4)=1, (Z4) rung, (Z5) igniting, and (Q9)=1, (D3) turn-off, (C4) begin charging, it is open-minded that water valve keeps, treat heat exchanger (4) cooling after, after promptly (C4) is full of, igniting is not combustion (this situation generally is that source of the gas is died) also, (BG1) ends, and water valve cuts out immediately, aqueous vapor interlock valve (9) cuts out thereupon, as also unignited in (t4) time, after promptly (C5) was full of electricity, carrying out igniting again negated program; If light, get back to flame-out preceding user mode again immediately.

During shutdown, press shutdown button (AN2), shutdown command keeps (C2) in (t6) circuit to be full of electricity immediately, and (P1) level point is 1 i.e. (E+), and after (AN2) discharging, (C2) by (R3) discharge, initiatively shutdown programm has just begun.(P1)=1, (Q2)=1, (Q6)=1, (BG3) end, (Z6) disconnect, (M2) counter-rotating is closed air valve (8), and flame promptly extinguishes, and makes (Q4)=(Q5)=1, (D4), (D5) also extinguish; (P1)=1, (Z1) begin the music of ringing, (Z4) do not ring; (Q2)=1, shutdown time of implementation (t1) the circuit trigger in (Z2); (Q4)=1 make (j)=0, (Q9)=1, (D3) turn-off, close (C4) that close in the water circuit behind the gas earlier and charged by (BG1) emitter stage, (R7), (R128), (R127), (BG1) continue conducting, water valve (2) still keeps original aperture.After treating that current are with heat exchanger (4) cooling, promptly to the charging current of (C4) during less than (BG1) conducting electric current, (BG1) by the saturation region through the amplification region to cut-off region, Vv is also reduced gradually, water valve (2) is promptly got back to rest position by the use location through the complete shut-down position gradually, emit surplus water, at this moment Vu=Vv in the machine.Because (BG1) end, thus water valve during through the complete shut-down position, even (ZT) closure can not make (BG2) conducting, so (M1) can not stop yet.When (t1) finishes, (J) discharge, power supply is cut off.

It is core parts with the music integrated circuit that assembly (Z1) rings in circuit middle pitch LXYES, the music integrated circuit kind is a lot, here enumerate the concrete structure of three kinds of formations (Z1), as shown in Figure 9, among Fig. 9 a, (IC7) (1) pin is a trigger end, (2) (3) pin connects sound-electricity conversion device, here use piezoelectric ceramic piece (FT1), power end (9) pin by (E+) through current-limiting resistance (R40) and Zener diode (D10) voltage stabilizing, supply with positive supply, (7) (8) pin connects oscillation resistance, (5) pin ground connection.When (2) of assembly (Z1) pin voltage changes to 1 by 0, send music through the differential trigger circuit triggers (IC7) that (C8), (R42) form.(IC7) available CW9300 also can be LM-M51 etc.Be to use CIC2800 series among Fig. 9 b, as the wiring diagram of CIC2851E integrated circuit, except that (9) pin and (5) pin of power supply were exchanged, other pin connection was the same.
