Detailed description of the invention
Figure 1 shows that a detailed description of the invention of water heater of the present invention. In this enforcement with Water storing electric heating waterDevice is example, and certainly the present invention also can be applied to the water heater of other types, as gas heater etc. Hot waterDevice 100 comprises the inner bag 10 for storing healed water. Conventionally be also coated with outside the tank shell (not figureShow) and be formed between inner bag and shell be filled with foamed material (as made by polyurethane material) everyThermosphere (not shown). Inner bag 10 is roughly extend along longitudinal axis direction barrel-shaped, and it has drum-shapedBucket wall, is made up of ferrous metal, conventionally as steel, iron etc. The bottom of inner bag 10 is provided with for cold water is drawnEnter a water inlet 81 in inner bag and for discharging a delivery port 82 of healed water. Water heater 100On shell, be conventionally also provided with hanger assembly (not shown), for be arranged on support member on body of wall (notDiagram) coordinate so that water heater is suspended on body of wall.
Water heater 100 also includes the heating component 20 for heating cold water. Embodiment as shown in Figure 1In, one first electric heating tube 21 is arranged on the first half of inner bag 10, and this heating tube is arranged on a first methodOn blue 31. The first flange 31 is arranged in the axial domed ends 11 of inner bag 10. The first electric heating tube21 from the first flange 31 horizontal-extending enter in inner bag 10, and further downwards wriggle and extend into inner bag 10The lower position place of the first half. In the first electric heating tube 21, be provided with a resistance wire with high impedance211, this resistance wire 211 is by wire (not shown) and be located at the positive and negative electrode terminal on the first flange 31(do not indicate) connects, with the AC power conducting of 220V or 110V, thereby be heat energy by electric energy conversion.Certainly, for other forms of water heater, as gas water heater, can be by arranging outside the tankCombustion chamber the liquid in inner bag is heated. One second and three electric heating tubes 22,23 jointly pacifyBe contained on second flange 32, this second flange 32 is fixed on the ball-shaped end 11 center of inner bag 10Position. Similar to the first electric heating tube 21, second and third electric heating tube 22,23 is all from the second flange 32Upper wriggling extends downward the bottom place near inner bag 10, is provided with equally resistance wire (not shown) in it.On the second electric heating tube 22, be also provided with a plate washer 221 at the water inlet position place of contiguous water inlet pipe 81, useGuide the cold water entering from water inlet and make it along lateral flow, thereby avoid it directly to enter and be positioned on inner bagLayer hot water layer and affect the efficiency of heating surface.
Water heater 100 also comprises a system for detecting temperature 90, and it at least comprises that edge is perpendicular to longitudinal axis directionFootpath the first temperature sensor 91, the second temperature sensor 92 that upwards distribute successively from low to high and theThree-temperature sensor 93. Temperature sensor can adopt various ways, as thermistor, temperature tube etc., usesIn the water temperature of surveying relevant position in inner bag, and be converted into the signal of telecommunication and feed back to controller 50, thus controller50 can be according to the temperature information receiving, and decides the control to these heating tubes (hereinafter will do in detail and retouchState). In the present embodiment, the first temperature sensor 91 is fixedly installed on inner bag 10 ball-shaped end 11Outer surface, this fixed form can be to be connected in to be welded on outside having on inner bag ball-shaped end 11 outer surfacesOn the cylinder of screw thread (not shown). Second and three-temperature sensor 92,93 be separately fixed at first andOn two flanges 31,32, and extend into the inside of inner bag 10. Certainly, in other embodiments, first,Two, three-temperature sensor all can select to be arranged on outer surface of liner or inner bag inside.
In the present embodiment, the first temperature sensor 91 is positioned at plate washer 221 tops close diametricallyPlate washer 221. By this set, the temperature that the first temperature sensor 91 is detected reflects position substantiallyIn the cold water layer temperature of inner bag low level. The residing axial cross section 16 of the first temperature sensor 91 and inner bag 10Bottom between defined a bottom volume V 0, because the volume of V0 is less, the first temperature sensor 91Can react rapidly, obtain soon the water temperature value T1 that represents V0. First and second temperature sensor 91,92Between residing axial cross section 16,17, define one first volume V 1; Second and third temperature sensor 92,Between 93 residing axial cross sections 17,18, define one second volume V 2; 93 of three-temperature sensorsBetween the axial cross section 16 at place and the top of inner bag 10, define a top volume V 3. Second and third temperature passesSensor 92,93 measured water temperature value are respectively T2, T3, wherein can use the mean value T12 of T1 and T2Represent the water temperature value of V1 part, the mean value T23 of T2 and T3 represents the water temperature value of V2 part, T3Represent the water temperature value of V3.
Show according to experiment, it is 50 liters of left and right that a normal adult human is had a needed hot water amount of bath;By that analogy, 2 to 4 needed hot water amounts of people are respectively 100 liters, 150 liters and 200 liters. NeedBe noted that here the hot water amount of indication refers to when bath comfort temperature T (as 40 degrees Celsius)The heat of mixing water yield after pure hot water and cold water mix. Certainly, in other embodiments, also can only add upThe amount of pure hot water, and then be converted into the corresponding heat of mixing water yield. Suppose in inner bag when the temperature TThe heat of mixing water yield is Vm, and the cold water temperature of water inlet is T0, and the total measurement (volume) of inner bag is V=V0+V1+V2+V3,Can obtain following equation according to thermal energy balance:
Vm*(T-T0)/V＝V0*(T1-T0)/V+V1*(T12-T0)/V+V2*(T23-T0)/V+V3*(T3-T0)/VWherein V0, V1, V2, V3 can be by arranging the position of first, second and third temperature sensor 91,92,93Pre-determine ratio, and the cold water temperature T0 of comfort temperature T and water inlet is known, that is to say,The water temperature value measured according to each temperature sensor, and then the inner bag part being associated according to these water temperature valueVolume, just can calculate in real time can be for the heat of mixing water yield Vm of bathing in inner bag.
For ease of calculating, in present embodiment, second and third temperature sensor 92,93 is of living in diametricallyPosition make the first volume V 1 equal the second volume V 2, and the first volume V 1 > bottom volume V 0. PreferablyGround, can also make first volume V 1=the second volume V 2=top volume V 3, that is to say second and third temperatureThe residing axial cross section 17,18 of degree sensor 92,93 is by residing the first temperature sensor 91 axial sectionThe more than 16 inner bag volume of face is divided into three parts, and the first residing position of temperature sensor 91 can makeV0/V1 is 1/3 ratio, thereby can greatly simplify the calculating of heat of mixing water yield Vm. Certainly this area skill,Art personnel can be understandable, and V1, V2, V3 in above-mentioned embodiment are equal in theory, butPossibly cannot guarantee to equate completely in engineering, can only make V1, V2 or V1, V2, V3 suitable, that is to say,Roughly equal, allow and have certain deviation. In addition, those skilled in the art can expect easily, go backMore temperature sensor can be set on inner bag, thereby make the calculating of heat of mixing water yield Vm more accurate.
Because the setting position of temperature sensor and the volume of inner bag part are associated, thus can be in real time alsoCalculate comparatively exactly the hot water amount in inner bag, to give user reference reliably.
Coordinate with reference to shown in Fig. 2 and Fig. 3, water heater also comprises input unit 51, display unit 52, withAnd be electrically connected with input unit 51, display unit 52, heating component 20 and system for detecting temperature 90Controller 50. Input unit 51 is for for user control program menu, selection function, adjusting temperature etc.,In embodiment as shown in Figure 3, input unit 51 comprises and is arranged in the some of display unit 52 bottomsTouch button B1-B8, is printed with respectively corresponding mark on these buttons, identify for user. ShowDevice 52 can show corresponding programs menu according to user's control, and other as temperature etc. mustWant information, it can be light emitting diode (Light-EmittingDiode, LED) display screen, also canWith liquid crystal (LiquidCrystalDisplay, LCD) display screen. In the present embodiment, show dressPut 52 for light emitting diode (LED) display screen. Controller 50 can be embodied in the simulation control of hardware or softwareCircuit, digital control circuit and the integrated circuit by microprocessor or microprocessor control. In this enforcementIn mode, controller 50 is microprocessor, and well-known to those skilled in the art, microprocessor canComprise CPU (CentralProcessingUnit, CPU), read-only memory module (read-onlyMemory, ROM), arbitrary access module (randomaccessmemory, RAM), time block, numberWord analog conversion module (A/Dconverter) and some input/output end ports. These I/OPort can be respectively and input unit 51, display unit 52, heating component 20 and system for detecting temperature 90Realizing communication receives data or signal and exports control signal. Certainly, controller 50 also can adopt otherThe integrated circuit of form, as application-specific IC (ApplicationSpecificIntegratedCircuit, ASIC) or field programmable gate array (FieldProgrammableGateArray, FPGA)Deng.
As shown in Figure 3, in present embodiment, on button B6, be printed with a humanoid mark, be used for for makingUser sets the number of wanting bathing. Respective regions 521 on display screen can show and represents bather numberMark, in present embodiment, is 4 humanoid marks. Certainly, in other embodiments, mark canOther figure or form, as the figure of the figure of shower nozzle, bathtub etc., or only by showing numerical valueMode represent bather number. Because these figures or display format are that those skilled in the art can think easilyArrive, so applicant is no longer repeated at this.
Shown in Fig. 4 is that the bather number that controller 50 is set according to user carrys out corresponding control heating component20 hot water amounts that adapt with heating. First, user sets and wants bathing by pressing button B6Number, then controller 50 receives the setting signal (step of this sign bather number by corresponding portRapid 611). For example, user presses button B6 No. one time, then add their confirmation by pressing OK button, thisTime just to have the people of a bathing chosen. Correspondingly, controller 50 will receive characterize a people washThe setting signal of bathing; Meanwhile, viewing area 521 can show the mark that represents bather number with first method,It is half bright that mark as humanoid in first becomes, and all the other are dark, shows that the people of a bathing is chosen. Similarly,Can set two, three or four bather numbers. Certainly, in other embodiments, can for setBather number can be more or a little less. Controller is receiving after setting signal, can determine with selectedThe corresponding hot water amount's of number reservation value, then controls heating component work, is next described in detail.Whether just at work controller 50 can detect heating component 20 (step 612), if, inspectionWhether the hot water amount who surveys in inner bag can have a bath (step 614) for setting number, whether reaches corresponding numberPredetermined value; If not, initialize to start heating component (step 613), then next carry outStep 614. As previously mentioned, the water temperature value that controller 50 can detect by system for detecting temperature 90 is come realTime calculate the heat of mixing water yield Vm in comfort temperature T having at present in inner bag, and judge whether to reachTo the hot water amount's who adapts with setting number predetermined value (step 615). For example, the bather number of setting isWhen one people, hot water amount's predetermined value is 60 liters. Correspondingly, the bather number of setting is two, three, four peopleTime, hot water amount's predetermined value is respectively 110 liters, 160 liters, 210 liters. If hot water amount has reached settingDemand, controller 50 can judge whether heating is also continuing (step 616), if, controlDevice 50 processed is controlled heating component quit work (step 617); If not, termination routine process (walksRapid 617). If hot water amount does not also reach setting demand, whether controller 50 can judge heating equallyAlso, continuing (step 619), if so, return to step 614, continue to detect hot water amount; If not,Controller 50 starts heating component work (step 620), next returns to step 614, continues to detectHot water amount, until hot water amount reaches setting demand.
Shown in Fig. 5, controller 50 can also be according to the hot water amount's real-time update display unit detecting52 demonstration. First, controller detect hot water amount Vm (step 620), then judge hot water amount with respect toWhether have before and increase or reduce (step 622). If hot water amount has increase, controller judges hot water againWhether amount reaches corresponding predetermined value (step 623), and for example, whether hot water amount Vm reaches for a people is washedBathe 60 liters, for 110 liters of two people's bathings, for 160 liters of three people's bathings and for four people210 liters of bathing. In the time that hot water amount reaches mutually deserved predetermined value, controller 50 is controlled display unit 52 moreNew show tags (step 625), shows with second method the mark that represents bather number. As work as hot water amountWhile reaching 60 liters, first humanoid mark from half bright become entirely bright; Correspondingly, when hot water amount reaches respectively110 liters, 160 liters, 210 liters time, second and third, four humanoid marks respectively from half bright become entirely bright. WhenWhen hot water amount does not also reach corresponding predetermined value, get back to step 622, continue to judge whether hot water amount hasIncrease or reduce. If hot water amount is compared to having reduced before, next judge that whether hot water amount is from correspondingPredetermined value has reduced specified quantitative (step 624); If so, upgrade show tags (step 625),Show the mark that represents bather number with Third Way; If not, get back to step 622, continue judgementWhether hot water amount has increases or reduces. In the present embodiment, this specified quantitative is 10 liters. That is to say,In the time that hot water amount drops to below 200 liters more than 150 liters, the 4th humanoid mark, by complete bright dimmed, showsThe hot water having in inner bag supplies three people's bathings only. Correspondingly, when hot water amount progressively drop to 150 liters,Below 100 liters, 50 liters time, the 3rd, two, humanoid marks are progressively by complete bright dimmed.
Those skilled in the art can expect easily, first, second and third demonstration in above-mentioned embodimentMode can be exchanged, and can certainly adopt other display mode, in filling Manchu shape markPortion region etc. Because water heater can show the mark that represents bather number, make the user can be according to thisThe demonstration of mark is set and is wanted the corresponding hot water amount of bather number, uses just thereby greatly improvedProfit; In addition, as long as due to heating as required, and water in will inner bag is heated to the state of full heat, fromAnd avoid energy waste.
Shown in Fig. 6 to Fig. 9 is controller is prepared hot water in advance work according to user's the bathing customSchematic process flow diagram. In the present embodiment controller can select at least two continuous first and second weeksPhase, then within the period 1, record user's use habit, then within second round, apply this useCustom, thus avoid user all will repeatedly set in advance at every turn. In the present embodiment, Cycle LengthBe a week, when having recorded after the use habit of first week, second week and each follow-up week all can answerUse this use habit, unless use habit changes, can the application in next week after changing change like thisUse habit after change. In the present embodiment, user can select by programs menu button B7This function, " intelligence weekly " function that viewing area 522 shows. After this function is selected, controller50 control flows shown in next will execution graph 6 to Fig. 9. Certainly, the time span in this cycle is notOnly limit to week, can be shorter than it, as day; Also can than length, as the moon, season etc.
Shown in Fig. 6, first, controller 50 can be set initial first period of short period length,As ten minutes, then detect the working time (step 631) of the heating component 20 in this initial first period,As heating component work in initial the first period five minutes. Subsequently, controller 50 calculated in this periodHeating water yield Vh (step 632). Conventionally heating component heat that can produce per minute under rated power,The water yield can record in advance, as 2 liters/min, same, if heating component work within initial the first periodDone five minutes, the hot water amount that produced is 10 liters. Next, controller detect this initialIn one period, whether there is hot water consumption (step 633), i.e. the using amount of hot water Vc > 0 in initial the first period whether.And the hot water amount Vh-that this period of Vc=heats by thermal source in this period of hot water amount Vm1+ in inner bag when initialHot water amount Vm2 when this period stops in inner bag. In the present embodiment, Vm1 and Vm2 are respectively initialThe heat of mixing water yield in courage when the first period started timing and when timing stops, as previously mentioned, this hot water amount canThe water temperature value detecting by system for detecting temperature calculates, and applicant is no longer repeated at this. AsIn initial the first period of fruit, there is no hot water consumption, controller is not carried out any operation (step 635). IfDetect in initial the first period and have hot water consumption, controller then judges whether it is heat to be detected for the first timeWater consumption (step 635), if so, can record initial time and initial hot water consumption. In this realityExecute in mode, initial time is the timing time started of this initial the first period, and initial hot water consumption is Vc.It should be noted that, in the present embodiment, controller, detecting it is for the first time after water, also can enter oneStep judges whether using amount of hot water exceedes a predetermined value, for example 10 liters (step 636). Because, if due toSpecial circumstances have just consumed a small amount of hot water, as the interim water situation such as wash one's hands, and these situations do not belong to conventionallyIn normal use habit, so can not need record. Therefore, if using amount of hot water does not exceed predeterminedValue, controller does not need to carry out any operation (step 636); If exceeded predetermined value, controller meetingRecord start time and initial hot water consumption (step 636). Get back to step 634, if controller detectsHot water consumption in this initial first period is not for the first time, show this initial first period be follow last at the beginning ofThe lasting water of the first period that begins, so controller does not need the record start time again, as long as at the beginning of originalThe new using amount of hot water (step 636) of accumulative total on beginning using amount of hot water.
Because the time span of initial the first period is shorter, if the time interval that hot water consumes is several times short, andEach time consuming is not long, and like this, controller just needs frequent starting heating group within second roundPart prepares hot water. So, as improving further, long initial of a time span can be setThe second period, this initial second period in time span, be at least more than or equal to two initial first o'clockSection, preferably, the time span of initial the second period can be arranged to times over or several times in initial theThe time span of one period. In the present embodiment, initial the first period is set to ten minutes, and initialTwo periods were set to two hours. Shown in Fig. 7, controller can record the heat of each initial the second periodWater behaviour in service (step 641). Concrete, controller can be by first appearance in this initial second periodInitial time is set as the initial time (step 642) of this initial the second period; By in this initial second periodThe initial hot water consumption of each initial the first period add up, as the initial hot water of this initial the second periodConsumption (step 643). For example, in initial the second period, there is the consumption of several times hot water, hot for the first timeThe initial time of water consumption is just as the initial time of this initial the second period, and several times hot water consumption accumulative totalTotal amount be the initial hot water consumption of this initial the second period. Certainly, if do not had in this initial second periodOccur hot water consumption, controller can not carry out record. When the hot water behaviour in service in this initial second periodAfter record, the record of this period of control unit end and enter the record of next initial the second period(step 644).
Shown in Fig. 8 and Fig. 9 be controller according to the hot water behaviour in service recording in the period 1, then existTwo embodiments of respective application in second round. As shown in Figure 8, when first controller can judge targetBetween whether arrived (step 651). Within second round, be provided with the period 1 in initial the first/bis-The the first/bis-period of target that period is corresponding, the initial time in initial the first/bis-period and corresponding targetObject time correspondence in the first/bis-period, and initial hot water consumption in initial the first/bis-period and correspondingThe the first/bis-period of target in target using amount of hot water suitable. " quite " of indication comprises complete phase hereDeng, also comprise some approaching equating in particular cases. For example, there is burst near before in the object timeProperty hot water consumption (as non-habitually bathing) and cause preparation using amount of hot water reduce. When controller is sent outWhen existing this situation, can start in time the using amount of hot water that heating component is reduced to supply, but supplementary heating timeBetween longer, in the time that the object time arrives, the using amount of hot water of preparation is not also supplied completely, just comparatively approaching. If detect that the object time also do not arrive, controller is not carried out any operation (step 653).If the object time arrives, whether next controller judge target using amount of hot water sufficient (step 652),Be whether target using amount of hot water is suitable with corresponding initial hot water consumption. If target using amount of hot water is enough,Continue to judge whether at work (step 654) of heating component, if so, controller control heating groupPart stops heating (step 654); If not, controller is not carried out any operation (step 657). AsFruit target using amount of hot water is also not enough, and whether at work controller can judge heating component (step equally655), if so, controller is not carried out any operation (step 657); If not, controller controlHeating component starts heating (step 658).
Fig. 9 has disclosed the embodiment of Another application. In the present embodiment, controller can judge currentWhether the initial time of period is positioned at the second half section (step 661) of this period. The period of indication is order hereThe first or second period of mark. Taking the second period as example, i.e. judgement when the initial time in the first two hour whetherBe positioned at latter one hour. If so, controller then judges whether the initial time of next period is positioned atIn its first half section (step 662); If so, show two waters in the period be continuous or interval veryNear, so, for avoiding starting continually heating component, these two periods can be merged with together follow-upPreparation using amount of hot water (step 664). Certainly,, if when the time span of this period is longer, can further sentenceWhether the initial time of disconnected current period is positioned at 1/4 time durations thereafter, and the next period is initialWhether the time is positioned at its time durations of front 1/4. Still taking the second period as example, current two hours riseTime beginning is positioned at 30 minutes thereafter, and meanwhile, whether the initial time of next two hours is positioned at its first 30 pointsIn clock.
If the initial time of current period is not positioned at its second half section, or the initial time of next periodBe not positioned at its first half section, or after two periods meet merging condition and merge, next controller can be sentencedWhether the target using amount of hot water of disconnected current period sufficient (step 663), if the current and next periodThrough having merged, whether judgement is the cumulative target using amount of hot water abundance of these two periods. IfThat controller is not carried out any operation (step 665); If not, controller calculating adds thermal target heatThe time (step 666) that water consumption need to heat. As previously mentioned, heating component is per minute under rated powerThe hot water amount that can produce can record in advance, so will produce the needed time of target using amount of hot waterJust can calculate thus. Next controller judges whether arrived (step 667), i.e. target preheating timeWhether the time span that the time, target using amount of hot water need to heat in advance forward again arrives. If arrived, controlDevice processed starts heating component heating (step 668); If be also less than, controller is not carried out any operation (stepRapid 668).
