Description

A kind of pre- temperature constant water heater

Technical field

The present invention relates to a kind of water heater, more particularly to a kind of open type hot hydro-thermal hydrophone.

" pre- constant temperature " in title of the present invention refers to that bather is being adapted to the hot water temperature's control for entering water tank certainly in advance In oneself scope, it be can be used directly during bathing without interim temperature adjustment.Winter, laundry clothes, water temperature control is beaten at 25 degree or so during wash vegetables Water cooling would not be felt by turning on the tap.It is of course also possible to control other temperature ranges required for you, extraordinary needs are met.

Technical background

Existing water heater species is various, respectively there is its advantage and weak point.1. gas heater, by improving latter oxygen The danger for changing carbon poisoning has been not present, and still, during normal work has a minimum startup amount, and preferable gas heater is general All at 3 liters per minute or so, water consumption is less than 3 liters, just can not start, only go out cold water, do not go out hot water.And human body is dirty when taking a shower Dirty 1.5 liters per minute of impregnation stage water consumption just can be with.Remaining hot water just wasting in vain.Another has the disadvantage, washes If cutting off the water or having a power failure during bath, it can not just continue bathing.Also have one disadvantage in that, gas heater is necessarily mounted at bath Outdoor, can only set up temperature in advance outside bathroom, into bathroom after cannot adjust bath water temperature again.2. instant electric water Device, although can quickly provide hot water, still, its power is too big, must be more than 6 kilowatts, and the supply line of general family all can not Needs are met, if forcing to use, easily trigger dangerous, if bathing can not also be continued by having a power failure during bathing.Its Electrical Safety It is also the problem of fears are entertained that.3. heat accumulation discharge type electric water heater, because water temperature therein is higher, in use, water must be adjusted temporarily Temperature.It is not whole all with water during bathing, but start-stop stops, and so, often stops once, it is necessary to a water is adjusted again Temperature, it is pretty troublesome.Most of water heater Cai Yong Unit handle water adjusting valves, often stop once, not only want water transfer temperature also to want water diversion volume, operate Come just more cumbersome.Often there is water temperature suitable and water is improper, water is suitable and the inappropriate situation of water temperature.Repeatedly adjusting During not only waste water but also waste the energy, also waste time.Increase many worries without foundation.Some water heaters enter to temperature adjusting structure Row is improved, and each start-stop need only control water yield, and leaving water temperature is still the same with the temperature mixed up just now.So, reduce Operation difficulty.But, because the fluctuation of hydraulic pressure, water temperature is difficult stabilization sometimes, or even during bathing, often opens and once use penstock Always first going out some cold water just goes out hot water.Cut off the water if being met during bathing, be to have full one case hot water, you can not also continue bathing, Because only running water enters after water tank, and the hot water of the inside could come out.Heat accumulation ability of swimming water heater is divided into open and closing again Two kinds of formula.Open to be saved with material, price is low, has the disadvantage to supply water at one.Closed many with material, manufacture difficulty is big, and price is high, Advantage is can multichannel water supply.Existing storage water heater when in use, when surplus hot water's temperature be less than suitable temperature when (common people Useful lower temperature limits are 35 degree or so) surplus hot water can not be continuing with.It is understood that the temperature of running water is well below 35 Degree just can make running water be warming up to 35 degree, it is necessary to consume much electricity.The relatively low hot water of this case temperature can only just stay in water tank In slowly cool off, so since the consumed electric energy of heating just waste.The reality in addition, water storage water heater is had a bath every time The surplus water for the other day for being all, Health cost can be caused to bath person.It is understood that impurities in water and chemical ion can pass through electricity Chemical action corrodes inner water tank, on the one hand can reduce the mechanical strength of inner water tank, lowers the service life of water tank.The opposing party Dough figurines are in order to reduce and reduce the various erosion carbon dioxides in water tank, and each producer all designs a lot of ways, such as, in water tank Middle increase " magnesium rod " etc., although these methods are effectively, but add cost, increases manufacture difficulty.And magnesium rod is easy Article is damaged, it is necessary to renew every several years, which increases use cost, and general user changes all without oneself, does not also know Road magnesium rod needs to change when being depleted to what degree, and this is all to belong to add to use difficulty.Water storage water heater is due to capacity It is larger, 100 liters -60 liters, power 1500w, it is necessary to 2 to 3 hours water temperature could be raised to predetermined temperature.Waited when every time with water Time it is oversize, having a bath needs time half a day.If in order to ensure to have at any time hot water can use, it is necessary to start constant temperature mechanism, Automatic heat preserving, it is average to need multi-purpose 1 to 2 degree electricity daily in order to be incubated.4. in order to overcome the shortcoming of foregoing various water heaters Once make a pre- constant temperature water storage formula water heater (Figure 21) by oneself, have a passage on the top of a water tank, bottom has one Individual through hole, bottom outer has a vertical tube to be fixedly connected with through hole, has one to use aquaporin in the middle part of vertical tube, by valve with drenching Bath head is communicated, and the bottom of vertical tube is communicated by valve with running water, can be supplied water into container.Be provided with water tank electric heating element and Thermometer probe, water tank lateral surface is provided with vertical transparent pipe, and transparent pipe bottom constitutes connected vessels type water with being communicated inside water tank Position meter.During bathing, open inlet valve and added water into water tank, water level is observed by water-level gauge, valve is closed when meeting needs.So After switch on power and begin to warm up.Need to control two parameters of water temperature and water in this operating process, because water temperature and water are Change respectively, and it is asynchronous, so this is really two processes.A. valve is first turned on to start to add water, it is necessary to wait one section It just can reach enough water levels after time, b. in order to heat up water, it is necessary to just immediately begin to lead in water flooding electric heating element as early as possible Electrical heating.Electric heating element is flooded from opening inlet valve to cold water, has individual waiting process, it is not also big problem to wait in fact, fiber crops Tired to be that bath person also notice whether observation water level floods electric heating element the moment, otherwise dry combustion method can burn out electric heating element.In addition, also Observe total Water number, lacked not enough, many waste energy and water, it is often more important that water temperature is controlled, because water is too warm Or it is too cool all can not bathing.So, it must be noted that to observe strict control when water temperature soon reaches predetermined value.Yet with common The response speed of thermometer is slow, delayed too big, and when showing 42 degree, actual 44 degree, therefore, operator must have rich Rich use experience, grasps certain lead, water temperature could be controlled in suitable scope, once the overheat burnt, is washed Water temperature will be adjusted during bath temporarily, could normal bathing.To be objective, such water heater from certain from the point of view of meaning actually Add the difficulty of operation.But this difficulty is disposable, this pass is crossed, this bathing will be comfortable satisfied, again not There is the situation of the small hydro-thermal water cooling of water flood during with each start-stop of worry.So this is that occur during bathing technological progress How difficulty, meaningful difficulty reduces this difficulty, and this will be task of the invention.Further, since water-level gauge is in water The side of case, and water tank must come back upwards in higher position, therefore during observation water level, it is very inconvenient, inaccurate water level is also seen, If, can be water-level gauge gear beyond the invisible in order to be incubated and be provided with enclosing, the moment grasps remaining water during bathing Amount will be more difficult, it has not been convenient to.This is also that needs are improved.

Technical problem

It is an object of the invention to provide during a kind of regulation and control of water temperature, operation difficulty is small, and the high heat accumulation ability of swimming of the temperature control degree of accuracy is pre- Temperature constant water heater, and providing can also further overcome the inconvenient and existing thermometer response speed of existing water-level gauge water level observation slow These are not enough, and the accurate control amount of heating up water, shower water amount, Electrical Safety, the power match of electric heater and circuit, wait mesh 's.And the predetermined warm hydrophone of the stable heat accumulation ability of swimming of performance in thermal procession.Performance is stable in so-called thermal procession refers to The change of water temperature is without departing from certain scope in the heating process of water, and the reduction of water temperature is also without departing from one in water utilizing process Fixed scope.This needs is ensured by certain design measure.

Technical scheme

To achieve these goals, the present invention include insulation hot water tank, thermometer, with aquaporin, with penstock, heating Device, inlet valve；Insulation hot water tank bottom surface has a main through hole to be fixedly connected with water main upper end, water main lower end and main frame The probe chamber of body is suitable for reading to be fixedly connected, and mouth is fixedly connected with heater delivery port under probe chamber, heater water inlet and water inlet Valve is fixedly connected, and inlet valve is fixedly connected with supply channel；The shank of thermometer probe seals and is fixed on probe chamber In aperture, head is located in probe chamber.

Beneficial effect

It can be seen from above-mentioned technical scheme that, the present invention belongs to " heater " externally positioned type water heater in architectural feature, Belong to hot water in terms of water temperature into type (foregoing various storage-type electric water heaters belong to cold water and enter type).Its heater can be Electric heater.Illustrate its advantage operationally by taking electric heater as an example below, electric heating element position therein is one It is individual much smaller than insulation hot water tank small space, when this space it is small to a certain degree when just possess i.e. hot water supply function.Can To imagine, in a miniature space, running water is quietly flowing through, and electric energy is generating heat dumbly, the hot water of outflow, and temperature is very Poised state is reached soon, water temperature no longer changes, by the detection of thermometer, if feeling improper, can adjust the big of inlet valve It is small water-carrying capacity is changed, so that leaving water temperature changes immediately, if improper, it can adjust again.Due to adjustment every time Used time is very short, even if so repeatedly adjustment, produced improper hot water amount also very little, the temperature influence on bath water total amount is micro- Its is micro-.It is again very short due to adjusting the used time every time, so user can carry out the operation of repeatedly adjustment water temperature.Always once you expire Meaning.Water main is both the passage that hot water enters water tank, is also the passage outside hot water stream outlet, so referred to as water main, if pressed As usual manage, be separately provided one and lead to the hot-water outlet pipe road at water such as gondola water faucet, it is also possible, but cost will be increased, And complicate product.

Heater in the present invention can be electric heater, and electric heating element is arranged in heating chamber, the delivery port of heater It is fixedly connected with mouth under probe chamber, the water inlet of heater is fixedly connected with inlet valve, electric heating element passes through electric wire, switch electricity Road is connected with power supply.

It is understood that the power of electric heater is bigger, heat up water faster, the time of wait is shorter, so water heater factory It is as far as possible big that the power that family and water heater user are intended to electric heater is done.However, because the concrete condition of user's house is each not Identical, the electric wire line footpath of new house is larger, can convey such as 10 kilowatts of very big power, the electric wire line footpath of old house typically compares It is smaller to convey 2 kilowatts, and existing electric heater when dispatching from the factory power be all fixed, it is impossible to change, the reality with user Situation is not necessarily matched.For safety, the power setting of most electric heater is 1500W, causes to heat up water small for up to 2 When.For the indoor line matching with user, electric heater capacity of the invention is adjustable.After user's purchase, installation personnel Power can be adjusted according to the actual track of user.The electric heating element of electric heater has several：

1, polar-plate-type electric heating element polar-plate-type electric heating element is by each not phase of the big metallic plate of one piece of area and several pieces of areas With small metal plate opposite it is parallel and fixation spaced apart is formed, can not be connected between every piece of adjacent small pole plate, Total length after arrangement, and arranged for interval spaced apart is less than or equal to the length of big pole plate, and large and small pole plate passes through switch Circuit distinguishes connecting to neutral line, and line of starting to exchange fire, if being full of water between pole plate, switches on power, and water, if anhydrous power off, works as institute with regard to heating The small pole plate having all connected by electric wire after be exactly polar-plate-type electric heater peak power, it is small by selectively disconnecting certain block Pole plate, you can obtain different power settings.

2, connect by on-off circuit after the different silicon nitride heating element in parallel of several pieces of power of silicon-nitride electric heating element Energization source, is exactly maximum power rating, can obtain different by selectively disconnecting certain block silicon nitride wiring pin Power setting.

3, resistance wire electric element is commonly called as " immersion heater ", and the connection of its circuit is as follows：High-power silicon controlled rectifier electronic pressure controller Two input terminals are connected by live wire, 0 line of on-off circuit and power supply, and two outlet terminals pass through electric wire and resistance wire electric The binding post connection of element, size that can be power setting to need by the knob of pressure regulator, switching on power can be by setting Fixed power work.

Certainly, electric heating element can also have other selections, pardon and seldom chat.

For Electrical Safety, electronic leakage protector is provided with existing electric heater circuit, if drain conditions Occur, can automatically power off.In the present invention, it is that bath person is protected by way of forcing power-off.Effect more preferably, can be with Absolute guarantee's safety.

The present invention, sets a water power mutually disconnected structure, when using water, electric heating element and electricity in the use aquaporin of host main body Opened from dynamic circuit breaker, it is ensured that even if electric heating element has damage, also will not be powered in bath water during bathing.In heating process, even if beating The use penstock with aquaporin end is opened, hot water outflow is there will not be.Concrete structure is as follows：

1, cover-plate type forces valve switch, and it is made up of jack base, cover-plate type plug and pressure valve.Water is used in main frame One pressure valve is set in passage, and the handle of valve is strip, and handle is located at handle with the pilot hole that valve element is combined End, the adjacent locations (rotation that can not hinder water valve strip handle) above valve set a jack base, and jack base faces Having on the wall of nearly water valve at 2 plug holes, 2 plug holes of jack base inwall respectively has 1 pair of conducting sheet of switch to be located at plug hole respectively Opposite side, there is 1 to be connected with power supply in the conducting sheet of switch in each hole, another 1 is connected with electric heating element, plug deck is length Cube, there is an elongated slot below, and size is adapted with strip handle, and there are 2 plug posts parallel with elongated slot the end of cover plate, There is conductive sleeve on post, the distance between plug post is adapted with plug hole, and external diameter and the plug hole internal diameter of conductive sleeve are adapted.Burn During water, cover plate plug post, which must be inserted into plug hole, can just switch on power, and condition is the elongated slot that strip handle must be with cover plate Parallel, cover plate can just insert in the hole, and now water valve will be in closed mode, when using water, it is necessary to pull out plug deck, force Power-off, could operate strip handle to open position, connect water route, opening penstock, hot water can just flow out.

2, poppet shaft forces valve switch to set a pressure valve in the use aquaporin of main frame, passes through rotary spool To switch water route, the two ends of poppet shaft extend to outside valve body, and wherein host housing is stretched out in one end, fix and connect with water valve handle Connect, a disk is fixedly mounted in the other end, two conducting strips can be provided with disk periphery with poppet shaft synchronous rotary, and Stagger 90 degree with the water route conduction phase of valve element, in host main body, have with two conducting strip positions corresponding position on disk periphery In two pairs of conducting sheet of switch, each pair conducting sheet of switch, 1 connection power supply, another 1 connection electric heating element when heating up water, twists valve element Axle makes water route be off state, now, and disk is rotated to switching the conduction on copper sheet opposite position, disk with poppet shaft Piece makes two pairs of conducting sheet of switch connections respectively, and electric heating element is heatable, when using water, rotation water valve handle to open position, water Road is connected, and disk is rotated with poppet shaft, and two conducting strips of its periphery leave on-position, the connection of electric heating element and power supply It is automatic to disconnect.Then, opening penstock, hot water can just flow out.

It is water tank type that hot water tank is incubated in the present invention, is exactly that outer surface has heat-insulation layer, with fixed profile chi Very little, inside can accommodate liquid and will not occur the ducted body of seepage, and its top surface has an air-vent, and there is main through hole bottom surface.Bottom surface " test formula water-level gauge " is mounted below, i.e., separately having in the bottom surface of water tank outside a water level hole, water tank bottom surface has a hard saturating Bright pipe is fixedly connected with water level hole, is had in water tank in a floater guiding pipe, the lower end insertion water level hole of guide pipe, upper end is placed in In the mounting hole of water tank top surface, mounting hole is with port lid with being threadedly coupled, and there is air-vent at port lid center.Lid can be prevented on guide pipe Lower play.Guide pipe upper and lower ends inside tank by through hole with communicating.Guide pipe, water level hole, transparent pipe three exists On one vertical curve.Float is placed in guide pipe, and a lower feeler lever is fixed below float, and lower feeler lever can be in transparent pipe with float Up and down, lower feeler lever bottom, which is provided with, the scale for showing different water levels on the water level indicating ring easily observed, transparent pipe Line.This is upper guide type.Lower guide type is can also be, is directly oriented to using hard transparent pipe, be exactly lower feeler lever Bottom is fixed on the centre of a centering ring, and the external diameter of centering ring is less than the internal diameter of hard transparent pipe, and centering ring is fixed , can be with float free floating behind feeler lever lower end.Centering ring external diameter can not be too small, otherwise loses centering function.Centering ring Main body is one section of pipe, in pipe or pipe end has a disk and pipe concentric and is fixedly connected, and disk had beyond central area Water hole several.The top of transparent pipe sets a centering piece with centre bore and water hole, and feeler lever is from centering piece center Passed through in hole, be limited in transparent pipe immediate vicinity.The certralizing ability at two will ensure that feeler lever is in the process of fluctuating up and down In, will not too it be tilted to some direction, resistance of being stumbled is in some position.Floating body only changes with the change of the water surface, feeler lever The water level indicating ring of lower end could accurately show water level.Centering ring also has the function of water level indicator, so, make water level indicate Ring.

It should be noted that water-level gauge can be separately provided, a main through hole in bottom surface can also be shared with water main, it is transparent Pipe can not only show water level, and a part for the passage of hot water tank can also be entered as heater hot water.So bottom surface can To reduce by a hole, overall more compact, cost is lower.

Water-level gauge is in hot water tank bottom, and container is fixed on the wall on bath person's head top, and new line can see water level clearly, i.e., Make to add enclosing to be incubated, also do not interfere with observing effect.

Insulation hot water tank can also be water-bag-type, or telescopic, their tops have an air-vent with it is big Gas phase is led to, and the air-vent on top has several effects, and 1, after the hot water that heater comes enters, the air of the inside can be discharged at any time, be held Pressure will not be uprised in device, and such hot water tank need not just be made firm very pressure-resistant, naturally, it is easy to manufacture, it is with low cost.2, Once imprudence, forgets shutoff valve, unnecessary water can overflow from this hole, and container will not burst.3, if without this hole, hot water tank Interior pressure slowly becomes big with the entrance of hot water, and such container must just be made solid, at this moment into the cold water of heater Can be fewer and fewer, (because pressure of supply water is constant, and water resistance becomes big, and discharge diminishes naturally), the heat so flowed out Coolant-temperature gage meeting more and more higher (being constant because the power of thermal source has been set when dispatching from the factory or when installing water heater), So the purpose of our pre- constant temperatures cannot reach.4, when using hot water, opening penstock, due to the presence in this hole, container Interior hot water just can normally flow out, can many places water supply.Every kind of insulation hot water tank has the heat-insulation layer adaptable with it, ability Ensure that water temperature stability is in predetermined temperature range during bathing.

In order to overcome the shortcoming that existing thermometer response speed is slow in the present invention, using thermocouple thermometer, trade name " point Temperature meter ", commercially available statistics have shown shows two kinds of commodity with pointer, and the present invention uses numerical monitor point thermometer.Existing water heater Compensation by thermistor, the final data of about 16 seconds ability displays temperatures are mostly used, and point thermometer need only be 2 seconds.When So, in the present invention, according to compensation by thermistor, even if its response speed is slow, each temperature adjustment, generation does not conform to Suitable hot water amount can be somewhat more, but its temperature adjustment operation is remained on than the electric heater built in existing electric heating body conveniently, Simply, accurately, remain to realize the purpose of the present invention,

The characteristics of first embodiment is；1 water-level gauge part is each independent with water main part.2 water tank bottom surfaces have Two through holes are communicated with water-level gauge, water main respectively.3 water-level gauges are lower guide types.4 have magnetic control water level automatic alarm Device.5. heater is the electric heater of power adjustable.

The operating method of first embodiment：For the first time in use, gondola water faucet 22 is placed below the position of electric heater, and Open and use penstock 20, then open inlet valve 17, there is water to initially enter in electric heater 6A1 heating chamber, when gondola water faucet has water During outflow, the heating chamber of expression electric heater expire by water, and this chronothermometer shows cold water temperature angle value, switches on power, electric heating element Start heating, due to heating cavity space very little, water temperature therein is raised quickly, and thermometer starts to show hot water temperature's value, about Time numerical value can be stablized within 20 second, exactly export the temperature of hot water, if needing water transfer temperature, and inlet valve 17 is opened big or turned down i.e. Can, hot water is exported with the water temperature after adjustment after several seconds.If not right, it can also adjust again, in a word, untill satisfaction.It is then shut off With penstock 20, and gondola water faucet is put into shower socket.Hot water is entered in water tank 1 with the temperature set by water main 30.When When filling hot water in water level pipe 2, float 11 is started to float and drives feeler lever 12, magnetic water level indicating ring 35 1 by buoyancy Rise as the water surface in water tank rises.Then, magnetic control water level automatic alarm device 80 is moved to some quarter needed of water level pipe Positioned at degree and with pinch 79.When float with the rise of the water surface in water tank drives magnetic water level indicating ring 35 to rise to alarm When near device, the magnetic action of water level indicating ring makes the tongue tube inside alarm connect warning circuit, sends alarm the tinkle of bells, i.e., Inlet valve 17 can be closed, so far, the process of heating up water terminates.During bathing, open and use penstock 20, hot water passes through flexible pipe 21 from gondola water faucet In spill.Afterwards in use, due to having had water in heating chamber, directly attaching plug can be inserted in socket, electric heating member Part starts heating, and cold water starts heating, opens inlet valve 17, and running water enters in electric heater 6A1 heating chamber, after being heated Into probe chamber, thermometer can show water temperature numerical value.If improper, it can open greatly or turn down inlet valve and water temperature is adjusted It is whole, until satisfied.The present embodiment is most basic electric heater.Temperature control protection can certainly be added on this basis and anti-dry Protection is burnt, one of anti-dry protection scheme is one rubber contact of setting in heating chamber, and contact is small in cavity wall through heating Hole, in the presence of hydraulic pressure, contact stretches out the movable contact spring for making protection circuit, static contact and contacted with each other, and circuit is to be switched on, Electric heating element starts heating.The benefit of protection circuit is that during normal heat up water, when cutting off the water, do not have in heating chamber Hydraulic pressure, rubber contact can be bounced back, and the dynamic and static contact separation of electric apparatus chamber, disconnecting circuit, electric heating element dead electricity is no longer sent out Heat, you can avoid being burned during dry combustion method, electric heating element is protected.This protection circuit is protected hydraulic pressure switch.If cut off the water When hydraulic pressure protection switch do not act, still can occur dry combustion method, in order to insure also add temperature detect switch (TDS) protection.Its work is former Reason is, when by high temperature, if it exceeds setting value, will automatic shutoff circuit, hydraulic pressure switch and temperature detect switch (TDS) are connected on master In circuit, duplicate protection is realized.Foregoing protection circuit is prior art, relevant with this in embodiment below No longer repeat in place.According to my experience, when heating up water, thermometer is stable at 42 degree.Heat up water after end, opening water Valve 20, tank hot water is flowed back downwards by water main 30, is 38-39 degree by displays temperature during thermometer, is drenched with, sense Feel just.By have weekly a bath consider, at this moment with dirt be not also a lot, the adhesion with skin is not also too strong, heat Water shower can start to wash dirt by rubbing with the hands for 5 minutes, wash hair, finally flush out bath.With 20 liters of water.Certainly, everyone bathing custom, Hobby is different, and water consumption is more or less not quite similar, can be aware of after oneself washing several times.When having a bath later, directly burn enough total Water is just.Bathing tips has 4：When 1 temperature when heating up water reaches 42 degree of stable states, the opening of inlet valve 17 is observed Angle, and mark is made with marking pen or other instruments, directly opened in place when heating up water next time.2 want to shorten wait The time heated up water, enough shower water amounts can be first burnt, after shower, close and use penstock 20, inlet valve is opened while giving a rubdown with a damp towel 17 burn enough rinse waters.So, the times such as the sky of half can be saved.3 summer weather are too warm, sweat of having a meal, and go into the street and turn One circle also can sweat, be badly in need of cooling remove sweat.Inlet valve 17 please be open, thermometer numeral is stable to be continued to burn 2-3 at 33 degree Minute, 3 liters of hot water can be enough.Because 20 degree or so of summer tap water temperature itself is higher, and have a shower also should not be too hot Water, so, burn a few minutes just it is enough.If 4 winters simply washed hair, 5,6 liters of hot water.But, to make thermometer steady Being scheduled on 45 degree just can be with.Because water tank is empty, after a small amount of hot water enters, radiating is than comparatively fast, water temperature can be somewhat low, so rising Beginning temperature should be high.

The beneficial effect of first embodiment is：1 when heating up water, and temperature control is accurate, simple to operate.During 2 bathing, it is not necessary to interim Water temperature is adjusted, hot water is wasted during can avoiding temperature adjustment, and the time is wasted, after opening, directly taken a shower, it is easy to operate.3 can It is accurate to control total
