Description
The invention relates to electric heater, particularly about a kind of invention of temp. and water controlling type separated electric hydrophone.
Temp. and water controlling type separated electric hydrophone of the present invention belongs to the category of water-storage electric heater; In other words; Temp. and water controlling type separated electric hydrophone of the present invention is a kind of novel water-storage electric heater.
Known to the applicant, utilize electric heater that resistance changes electric energy into Joule heat from the simplest electric furnace, the update through over one hundred year has developed into one and has had multiple use.The electric heater extended familys of multiple pattern, and be the electric heater of main application to take a shower, generally can be divided into two major types at present, be continuous-flow type electric heater and water-storage electric heater, the continuous-flow type electric heater is not stored the water storage tank of hot water, cold water flows through the large power, electrically thermal element of heating power and Fast Heating during use, becomes hot water immediately and flows out the supply people and use; Water-storage electric heater has heating cold water and the temporary transient water storage tank of storing hot water, and after the cold water heating, people cut off the electricity supply with switch earlier, re-use hot water, thereby as safe as a house when taking a shower.
Known to the applicant, the overwhelming majority's that present people are general electric heater all is a water-storage electric heater, although the water-storage electric heater profile of various brands varies, but its primary structure is then similar, basically can serve as typical case's representative with No. 2036269 described water-storage electric heaters of patent of Britain, their technology be held and is levied generally and can be summarized as follows.
From the hot water temperature that electric heater produces, general water-storage electric heater all belongs to " high temperature modification " at present; Be that the hot water temperature that they produce necessarily is higher than the desired preference temperature of owner; To add cold water by hot water or cold water's mixing valve of a complexity when hot water of these " high temperature " uses, after adjusting, can obtain the hot water of needed preference temperature through excess temperature.In the operation of adjusting temperature, owner promptly needs some times of spend, also must waste some hot water, thereby seem some inconvenience.
Style from electric heater, all popular in always electric switch, indicator lamp, temperature adjustment button etc. all is installed on the water storage tank, the setting height(from bottom) of electric heater that this class belongs to " monomer-type " category is all very low, if the height of installing is very high, owner sees indicator lamp, and manipulation temperature adjustment button, electric switch will seem inconvenient; And according to about water tank bottom of current trend apart from ground 1.5 meter amperes dress, add hot water or cold water's mixing valve of its bottom, it will occupy the effective usable floor area of a fritter of toilet undoubtedly.
Water storage mode from water storage tank, how many flow of hot water at present most water-storage electric heaters promptly has in case after using, all be " permanent water storage " in the water storage tank, just must there be how much cold water to flow at that time and replenished, keep " full water " state in the water storage tank forever.Be the corrosion of anti-sealing to water storage tank, present a lot of water storage tanks all use expensive rust stable material to do inner bag, for example use stainless steel to do inner bag; Also additional " the stream electric anticorrosion device " that the anti-corrosion of being exclusively used in is arranged of the water storage tank that has.Water storage tank " permanent water storage " also has three bad solutions of minor issue except " corrosion " this big problem, first problem is after finishing using at every turn, necessarily also has full one case hot water to utilize in the water storage tank; Second problem is if the long time is not used electric heater, and the shipwreck of storing in the water storage tank is difficult to guarantee can not form precipitation and incrustation scale to guarantee not can water quality becoming sour rottenly; In addition, northerly cold district, in a single day the water in the water storage tank freeze, and may cause the water storage tank bursting by freezing and scrap.
Except above-mentioned prevailing electric heater, the new-type electric heater that also occurred a spot of a kind of belonging to of " half control warm type monomer-type " category in nearly 2 years on the market, the water storage tank that so-called " half control temperature " is meant this class electric heater is all smaller, general capacity is 25～30 liters, the hot water amount who needs owner is during less than the capacity of water storage tank, and it can produce the suitable hot water of temperature for owner by the temperature control knob; But the hot water amount who needs as owner is during greater than the capacity of water storage tank, and it still has to use old way, promptly produces the hot water of " high temperature ", still needs to add cold water and carries out temperature adjustment and just can obtain the hot water that temperature suits.
Order of the present invention ground is some deficiency of wishing to improve as much as possible existing water-storage electric heater, and electric heater can be taken a shower and the needs of other purposes carry out the control of the temperature controlling and the water yield by owner; Be the hot water how many temperature owner needs, it just can produce the hot water of how many temperature; Owner needs the hot water of how many water yields, and it just can produce the hot water of how many water yields; In addition, the applicant also wish the water storage tank of electric heater to be installed in the bottom apart from ground at least greater than in 2.20 meters the space, this electric heater that can save the effective usable floor area in toilet, can alleviate the degree of crowding of narrow toilet, simultaneously, its installation site also is easier to select.The applicant wishes, this function that has the control temperature simultaneously, and the function of the control water yield and the appearance that can save the electric water heater of the effective usable floor area in toilet can bring some facilities for daily life.
Through concentrating on studies, this so-called temp. and water controlling type separated electric hydrophone has been trial-produceed successfully finally; The present invention is achieved in that
In order to make electric heater produce hot water according to the temperature that owner needs, the applicant has quoted the industrial temperature indication adjusting apparatus that has been extensive use of the water temperature in the water storage tank is automatically monitored and controlled; Thereby reach the order ground of " temperature control ".The topmost technical characterictic of the temperature controlling function of this electric heater is; Having quoted the industrial temperature indication adjusting apparatus that has been extensive use of automatically monitors and controls the water temperature in the water storage tank, after hot water reaches the temperature of owner with the setting of temperature control knob, temperature indication adjusting apparatus will automatically cut off the power supply of heating, make heating stop heating; Because of after cooling the has faint cooling, temperature indication adjusting apparatus will automatically recover the power supply to heating, the preference temperature that makes the water in the water storage tank always keep owner to set again at thermophilic hot water; Owner must not add cold water again hot water is done the temperature adjustment when using this hot water, can directly use.
In order to make electric heater in water storage tank, add water according to the water yield that owner needs, the applicant is a kind of so-called " water and heat provision automatic control circuit " for electric heater has designed, as long as owner's water consumption control knob (also can claim water yield gauge tap) configures the needed water yield, the water and heat provision automatic control circuit just can be monitored the water yield in the water storage tank by a kind of so-called " water level switch ", after the water yield in water storage tank reaches the water yield of setting, water level switch will automatically closedly be connected the water and heat provision automatic control circuit, and at this moment the water and heat provision automatic control circuit will be by the power supply of a water supply electromagnetic valve of a contactor " disconnection ", make the water supply electromagnetic valve valve-off, stop in water storage tank, adding water, thereby reach the order ground of " control water ".The topmost technical characterictic of the control water function of this electric heater is: have a water supply electromagnetic valve to serve as conventional running water switch on the water supply line in water storage tank; The coil of water supply electromagnetic valve is connected with the contact switch of a contactor, and the coil of contactor is cascaded with a water yield gauge tap, water yield gauge tap relies on a plurality of fixed contacts and an armature contact, can carry out single optionally connecting with the water level switch of one group of parallel connection, thereafter, water level switch is connected with power supply again; Form one by contactor coil, water yield gauge tap, the water and heat provision automatic control circuit of the closure that water level switch, power supply are formed, and the contact switch of contactor are then being controlled the coil of water supply electromagnetic valve in the water supply circuit; Connect some water level switches of having connected if owner transfers water yield gauge tap to move on demand, the water in water storage tank increases gradually and rises when reaching the water level that this water level switch controls, and water level switch will automatically closedly be connected the water and heat provision automatic control circuit; At this moment, will there be electric current to pass through in the water and heat provision automatic control circuit; At this moment, the coil of contactor will produce contact switch " disconnection " water supply circuit that electromagnetic action makes contactor, make water supply electromagnetic valve no longer produce the electromagnetic action valve-off because of coil has a power failure, thereby stop adding water in water storage tank.
Can save effective usable floor area of toilet when mounted to greatest extent in order to make electric heater, the applicant's general " monomer-type " electric heater at present is improved to so-called separated electric hydrophone, and this its major technique of electric heater with so-called split-type structural is characterised in that; With various indicating devices, suggestion device, the control device that should be placed in originally on the electric heater water storage tank, for example its circuit such as indicator lamp, buzzer, electric switch, temperature control knob still design by original principle, but when concrete split design, the method by extension lead then, they are removed from water storage tank, and design and installation is in a control box that independently volume is very little; Except various indicating devices, suggestion device, outside the control device, other device then also should be installed on the water storage tank of electric heater as much as possible; By a kind of like this improvement, the circuit of electric heater does not change, and service behaviour does not change yet, but it has told the control box that some leads of a usefulness and water storage tank are being got in touch, and people use electric heater to handle by control box; Like this, the water storage tank of separated electric hydrophone require to be installed in the bottom apart from ground level at least greater than in the space more than 2.20 meters; Such space that water storage tank occupies, it is the idle space that can't use in people's daily life, although and the control box setting height(from bottom) is low, but its volume is small, can not take how many effective usable floor areas of toilet, because the separated electric hydrophone can be saved effective usable floor area of toilet, so it not only selects the installation site easily in narrow toilet, and can alleviate the degree of crowding of toilet.
The applicant is when development temp. and water controlling type separated electric hydrophone, except considering " temperature control ", " control water ", " split " three big factors, also considered the water storage mode is changed into " temporary transient water storage " mode, promptly electric heater will not have water in time spent not in its water storage tank; The change of this water storage mode makes original inner bag corrosion, waste hot water, and water quality degenerates, and problems such as water tank bursting by freezing are readily solved.In addition, the applicant has also considered the factor of " handiness "; For this reason, the applicant requires temp. and water controlling type separated electric hydrophone when in a single day owner needs to use hot water, need only configure preference temperature with the temperature control knob, the water consumption control knob configures proper discharge of water, thereafter behind " closure " circuit general switch, it just can automatically carry out and finish 5 working procedures; When owner's " disconnection " circuit general switch uses hot water, it also will automatically enter the 6th working procedure; These 6 working procedures are as follows:
1, in owner's closure behind the master switch of electric heater, the water supply electromagnetic valve as running water switch in the water supply line can automatically be opened valve, begins to add water for water storage tank.
2, after the water yield in water storage tank increased to the proper discharge of water of owner's setting, water supply electromagnetic valve is valve-off automatically, no longer adds water in water storage tank.
3, when water supply electromagnetic valve stops to add water in water storage tank, heating will automatically begin heating, produce heat heating cold water.
4, after the water temperature in water storage tank is increased to the preference temperature of owner's setting, heating circuit will automatically be switched " off ", and make heating stop heating.
When 5, the thermophilic hot water in water storage tank has faint reduction because of slow exothermic temperature, heating circuit will automatically be " closed " connection again, make heating produce heat again, water temperature is conditioned all the time keep the preference temperature of owner's setting.
6, owner's " disconnection " behind the master switch of electric heater, to there be one group of water level indicator light can be automatically shinny on the control box, every lamp of these water level indicator lights is being represented a water level, and owner can know to also have how much hot water in the water storage tank by these water level indicator lights when using hot water.
According to the applicant's research, find after having designed a kind of so-called " water level switch ", can make circuit automatically realize the 1st, the 2nd, the 3rd and the 6th working procedure at an easy rate for temp. and water controlling type separated electric hydrophone.Water level switch is the automatic control component of most critical in the water and heat provision automatic control circuit, its technical characterictic of so-called water level switch is: the water level switch on the some water levels in water storage tank, when water also rises when reaching this water level, water level switch is in " disconnection " state, when water rises when having reached this water level gradually, water level switch automatically immediately " closure " turns on the circuit at this place; Water level switch can carry out diversified design according to different design principles, only introduces two kinds of water level switches the simplest this applicant.In water, has buoyancy and the natural law on bubbling through the water column according to buoyancy aid, can design as shown in Figure 1 " metal float-ball type water level switch ", metal float-ball type water level switch is mainly by a hollow metal ball float, and a float chamber and two conductive metal sheets are formed; The metal ball float is positioned in the float chamber, one or several duck eyes that supply water and pass in and out are arranged at its underpart, float chamber that is made of plastics or bottom, the top then hides with screw and is fixing two conductive metal sheets, two conductive metal sheets are connecting lead respectively, be separated by nearer between them but do not contact, and make projection upwards slightly at the middle part of float chamber, when in the float chamber, not having water, the metal ball float is positioned at the bottom, float chamber because of gravity, the water yield increases gradually in water storage tank, when water level rises to the float chamber, have water to flow in the float chamber, the metal ball float is bubbled through the water column because of buoyancy, along with the continuation of water level is risen, the metal ball float contacts with two conductive metal sheets at top, float chamber the most at last, at this moment the metal ball float is arranged for their delivered currents between two conductive metal sheets, and promptly metal float-ball type water level switch closure has been connected the circuit at this place; In water, have buoyancy and the natural phenomena of bubbling through the water column according to buoyancy aid, can also design as shown in Figure 2 " fixedly float type water level switch "; Fixedly the float type water level switch mainly adds a buoyancy aid that is fixed on the elastic contact blade by a contact switch and is formed; Water in water storage tank does not rise when reaching the residing water level of water level switch, water level switch is in " disconnection " state, after water increase in water storage tank has reached the residing position of water level switch, buoyancy aid will produce buoyancy with the elastic contact blade jack-up that makes progress, two contacts of contact switch are contacted, at this moment, water level switch has been connected the lead at its two ends, and promptly fixedly float type water level switch closure has been connected this place's circuit.
Water level switch is the automatic control component of most critical in the water and heat provision automatic control circuit, a water level switch can be controlled a water level, water levels different in the electric heater water storage tank are settled several water level switches respectively, the water and heat provision automatic control circuit just can carry out control automatically to these different water levels so, and so-called its technical characterictic of water and heat provision automatic control circuit is; Coil one end of the contactor power supply of connecting, the other end is connecting the armature contact of a water yield gauge tap, between water yield gauge tap and power supply, connecting the water level switch that several are positioned at different water levels in parallel, these water level switches are connected respectively on several fixed contacts of water yield gauge tap accordingly, its armature contact is when accent moves, can only contact with a fixed contact at every turn, be that water yield gauge tap can only closedly be connected a water level switch at every turn, thereby form the circuit of a closure; In this so-called water and heat provision automatic control circuit, water yield gauge tap is that owner sends the parts that need water yield instruction to electric heater; How many water yields owner needs, water yield gauge tap can be transferred move and connect the water level switch of controlling this water yield, at this moment, have only this water level switch will enter duty and monitoring the water yield in the water storage tank according to owner's instruction, because whether other water level switch oneself no matter " closure ", it water yield gauge tap here circuit be " disconnection "; When the water yield one reaches the water yield of owner's needs, this water level switch that has entered duty will automatically closedly be connected whole water and heat provision automatic control circuit, and at this moment, power supply will provide power, and the coil of electric current by contactor arranged; At this moment contactor will be carried out owner's instruction, i.e. " disconnection " water supply circuit, and it is also with " closure " heating circuit simultaneously.
Water and heat provision automatic control circuit control water supply circuit, the schematic circuit of heating circuit is as shown in Figure 3; In the water and heat provision automatic control circuit, power supply can be an alternating-current power supply, also can be dc power supply; But consider coefficient safe in utilization that improves owner as much as possible and the needs that water level indicator light is installed, in Fig. 3, used a dc power supply of forming by transformer and bridge rectifier; Because the self-induction action of contactor coil has filter effect, so there is not special filter element in the circuit of dc power supply.In circuit shown in Figure 3, used 6 metal float-ball type water level switches, water yield gauge tap has 6 fixed contacts, so circuit shown in Figure 3 makes electric heater have " control water " function of selecting 6 kinds of different water yields.In the circuit of reality, can use 10 even 20 so that more water level switch, thereby electric heater be had select 10 kinds even 20 kinds so that the control water functions of the more different water yields.
Water and heat provision automatic control circuit control water supply circuit, the technical characterictic of heating circuit is; After owner's water consumption gauge tap had been connected a water level switch and promptly set a proper discharge of water that oneself needs, he is the closed circuit master switch again; At this moment, have electric current to pass through in the coil of water supply electromagnetic valve, the electromagnetic action that it produces is inhaled the valve of having opened water supply electromagnetic valve, and making electric heater enter the 1st working procedure is that running water flows into water storage tank through water supply electromagnetic valve.The water yield in water storage tank increases water level gradually and rises when reaching the water level of the water consumption that owner sets, and the water level switch that is positioned at this water level will automatically closedly be connected whole water and heat provision automatic control circuit.At this moment, alternating current, is changed into direct current by transformation, rectification, filtering and flows in the water and heat provision automatic control circuit through the flow through primary coil of transformer of circuit general switch from power supply; At this moment, the coil of contactor produces electromagnetic action, makes the armature contact of contacts of contactor switch transfer on the contact that connects heating circuit from the contact that connects water supply circuit; At this moment, water supply circuit " disconnection ", water supply electromagnetic valve thereby valve-off have stopped adding water in water storage tank; At this moment, heating circuit " closure ", and heating begins heating heating cold water.Be that at this moment electric heater has automatically finished the 2nd working procedure, automatically entered the 3rd working procedure.
The heating of heating power is constantly emitted heat constantly raises the water temperature in the water storage tank, after it has reached the preference temperature of owner's setting, electric heater is necessary by making heating stop heating someway, and when water temperature because of after cooling the has faint decline, electric heater also is necessary by heating is generated heat again.Industrial, people at present widely serviceability temperature indication adjusting apparatus finish adjusting work to water temperature; The applicant thinks, utilizes this existing automatic control technology, selects for use the temperature indication adjusting apparatus of certain suitable model to be installed in the electric heater, and electric heater is realized the 4th, and the 5th working procedure will become very easy.
Common all temps indication adjusting apparatus usually all is made up of three systems:
1. temperature-sensitive system: mainly form by temperature-sensing element and transducer wire.The characteristics of temperature-sensing element are along with variation of temperature, and its resistance value is also changing, and under certain voltage conditions, the electric current by temperature-sensing element is also constantly changing.Temperature-sensing element divides thermocouple, thermal resistance, thermistor three major types, and they generally all make probe shape or probe shape, place among the water body of being surveyed.Select temperature-sensing element for temp. and water controlling type separated electric hydrophone, should consider to be chosen in the temperature-sensing element that performance is best, price is lower again in 0～100 ℃ of scope, for example select the copper resistance of Cu100 for use.Transducer wire is connecting temperature-sensing element and temperature indication adjusting apparatus, is responsible for varying with temperature and the weak current that changes flows to temperature indication adjusting apparatus.
2. temperature indication mechanism: mainly the ammeter that has been scaled temperature by an amplifying circuit and current strength is formed, after the weak current that amplifying circuit transports transducer wire amplifies, pass through ammeter again, promptly can know the water temperature of the water body of surveying by the indicated scale of ammeter pointer.
3. humidity control system: mainly form by temperature set mechanism and one " great number vibration---power amplification circuit " and an external high power relay.Obtained by the temperature adjustment button in humidity control system after the temperature value of owner's setting, the water temperature signal of telecommunication that it will be constantly automatically transports this set temperature value and transducer wire compares, after temperature reaches or is reduced to the temperature value of owner's setting, it will be exported to high power relay, and heating circuit should " disconnect " or the instruction of " closure ", thereby is controlling whole heating circuit effectively.
In temp. and water controlling type separated electric hydrophone with temperature indication adjusting apparatus be the temperature regulation circuit formed of core as shown in Figure 4, it is characterized in that: two power leads on the temperature indication adjusting apparatus are connected on respectively on the phase line of single-phase alternating current and the neutral conductor to obtain operation power; Two transducer wires are connecting temperature-sensing element transmitting the water temperature signal of telecommunication that temperature-sensing element obtains, two signal output leads high power relay coil of connecting; The contact switch of the high power relay heating on the heating circuit of then connecting, owner has set a suitable hot water water temperature by the temperature control knob after, the water temperature signal of telecommunication and this set water temperature that temperature indication adjusting apparatus will constantly automatically pass over transducer wire compare, when the water temperature in water storage tank is lower than set water temperature, the high power relay contact switch is in " closure " state, electric current can pass through herein, and heating is in the duty of heating heat supply; After water temperature in water storage tank reaches the suitable water temperature of owner's setting, in the signal output lead of temperature indication adjusting apparatus signal of telecommunication output is arranged, the coil of electric current by high power relay promptly arranged; Under the effect of electromagnet, the contact switch of high power relay " disconnection " heating circuit, therefore heating stops heating; Water temperature in the water storage tank no longer raise from this moment, and transferred the state of slow radiating and cooling to; When water temperature has faint reduction, temperature indication adjusting apparatus will stop to the signal output lead output signal of telecommunication, and because of not having electric current by there not being electromagnetic action, contact switch automatically returns back to original " closure " state again in the high power relay coil; At this moment, heating begins heating again, and water temperature is returned to the suitable water temperature that owner sets; So repeatedly, the water temperature in the water storage tank will be regulated always and kept the suitable water temperature that owner sets.Hence one can see that, and after water temperature reaches preference temperature, if owner can not use hot water in time, the 4th working procedure of electric heater and the 5th working procedure will hocket, to keep the water temperature of setting.
The applicant thinks: cast out the temperature indication mechanism of temperature indication adjusting apparatus, can design a kind of thermoregulator of special use for temp. and water controlling type separated electric hydrophone; Substituting temperature indication adjusting apparatus with thermoregulator can reduce production costs significantly; But function of use does not obviously weaken.Certainly how thermoregulator designs, not among the category that this paper discusses.
After owner has disconnected the circuit general switch of electric heater, use in the process of hot water, it is necessary manage to allow owner understand at any time approximately also having how much hot water in the water storage tank, for this reason, the applicant's specialized designs a water level indicator light system to satisfy owner at the needs aspect this.
This basic circuit that has disconnected water level indicator light system that behind the circuit general switch still can be automatically shinny as shown in Figure 5, its technical characterictic is: battery in parallel on dc power supply, the negative pole of battery is connected on the negative pole of dc power supply; The positive pole of battery then is connected on the another one and the alternating-current power supply of contactor in the water and heat provision automatic control circuit, on the contact switch that water supply circuit, heating circuit have nothing to do, on two contacts of the other end of contact switch, a contact is connecting the positive pole of dc source with a lead; A contact is then connecting the water level indicator light of one group of parallel connection, and these water level indicator lights are connected respectively on each fixed contact or near lead of water yield gauge tap separately accordingly; When in the water and heat provision automatic control circuit, having electric current to pass through, the contact switch closure has been connected battery " electric power storage " circuit, make battery enter the readiness for operation of " electric power storage ", " disconnection " behind the circuit general switch, the dc power supply of being made up of transformer and bridge rectifier has also disappeared thereupon.At this moment, also will not have electric current to pass through in the water and heat provision automatic control circuit, the armature contact of contactor has also been lost electromagnetic force because of contactor coil and has been kept in the center, and contacts with the fixed contact that is being connected water level indicator light, has connected the circuit of water level indicator light closed; At this moment, battery has entered the duty of " discharge ", at this moment, battery, water level indicator light, water level switch will be formed several current loops in parallel, the water level indicator light of each water level bright with do not work, depend on whether water level switch has connected circuit.A certain small cup water level indicator light is bright, reflects that the water in the water storage tank also has this water level indicator light representative water level at least.As shown in Figure 5, the metal float-ball type water level switch of uppermost two high water level of water storage tank, because of the water level no show can not be floated the connection circuit, so there are two high water level indicator lights of corresponding with it water level can not be shinny, and other water level indicator light has surpassed the water level of they representatives because of water level, their water level switch has been connected circuit, therefore can both be shinny.
As a kind of split type electric heater, be to be connected with the some leads that prolonged between its water storage tank and the control box, when concrete split design, which root lead needs prolongs, which root lead does not need prolongs, and can judge according to the connection features of this root lead; The lead that need to prolong is characterized in that: the parts that lead two ends are connecting are if be installed in respectively in water storage tank and the control box, the lead that need prolong when then this root lead must be the split design; For example, water level switch in temp. and water controlling type separated electric hydrophone and water yield gauge tap, temperature-sensing element and temperature indication adjusting apparatus, heating and circuit general switch, the lead between them must be the leads that needs prolongation.
Water and heat provision automatic control circuit, water supply circuit, heating circuit, temperature regulation circuit, the water level indicator light circuit that discuss comprehensive front; We can conclude the basic circuit diagram of the temp. and water controlling type separated electric hydrophone that draws as shown in Figure 6.
In this basic circuit diagram, water level switch has used metal float-ball type water level switch, Temperature-controlled appliance has used temperature indication adjusting apparatus, but in practical design, water level switch can also use other type, Temperature-controlled appliance also can be selected other type or special-purpose thermoregulator for use, in addition, such as contactor, high power relay, water supply electromagnetic valve, temperature-sensing element, heating, transformer, diode, battery etc., its model yet must carefully be selected according to every design parameter in concrete design; Some parts might also need to carry out special design.In concrete design, it also is necessary revising these circuit theory diagrams according to some parameter and some needs.
According to the described circuit theory diagrams of Fig. 6, temp. and water controlling type separated electric hydrophone produces the hot water that temperature is suitable, the water yield is suitable for owner, 6 working procedures of carrying out are automatically arranged, contrast circuit theory diagrams earlier at this these 6 working procedures are done simple an elaboration:
