The specific embodiment
Shown in Figure 1 for a specific embodiment of water heater of the present invention.In this enforcement, be example with the storage-type electric water heater, the present invention also can be applied to the water heater of other types certainly, like gas heater etc.Water heater 100 comprises and is used to store the inner bag 10 that is heated water.Usually also be coated with shell (not shown) outside the tank and be formed on inner bag and shell between the thermal insulation layer (not shown) that is filled with foamed material (as processing) by polyurethane material.Inner bag 10 roughly is the round barrel shape that extends along the longitudinal axis direction, and it has drum shape bucket wall, is processed by ferrous metal usually, like steel, iron etc.The bottom of inner bag 10 is provided with and is used for cold water is introduced the water inlet 81 in the inner bag and is used to discharge a delivery port 82 that is heated water.Usually also be provided with hanger assembly (not shown) on the shell of water heater 100, be used for and the support member (not shown) that is arranged on the body of wall cooperates so that water heater is suspended to body of wall.
In this embodiment, first temperature sensor 91 is positioned at plate washer 221 tops and diametrically near plate washer 221.Through this set, make the temperature sensor 91 detected temperature of winning reflect the cold water layer temperature that is positioned at the inner bag low level basically.Defined a bottom volume V 0 between the bottom of first temperature sensor, 91 residing axial cross sections 16 and inner bag 10, because the volume of V0 is less, first temperature sensor 91 can react rapidly, obtains to represent the water temperature value T1 of V0 soon.The residing axial cross section of first and second temperature sensor 91,92 16, defined one first volume V 1 between 17; The residing axial cross section of second and third temperature sensor 92,93 17, defined one second volume V 2 between 18; Defined a top volume V 3 between the top of three-temperature sensor 93 residing axial cross sections 16 and inner bag 10.Second and third temperature sensor 92,93 measured water temperature value are respectively T2, T3, and the mean value T12 of wherein available T1 and T2 represents the water temperature value of V1 part, and the mean value T23 of T2 and T3 represents the water temperature value of V2 part, and T3 represents the water temperature value of V3.
Show that according to experiment it is about 50 liters that a normal adult human is had the 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.Need to prove that the hot water amount of indication is meant pure hot water and the heat of mixing water yield after the cold water mix when being in bath comfort temperature T (as 40 degrees centigrade) here.Certainly, in other embodiments, also can only add up the amount of pure hot water, and then be converted into the corresponding heat of mixing water yield.Suppose in the inner bag be in temperature T the time the heat of mixing water yield be Vm; The cold water temperature of water inlet is T0; The total measurement (volume) of inner bag is V=V0+V1+V2+V3; Wherein V0, V1, V2, V3 can come to confirm in advance ratio through the position that first, second and third temperature sensor 91,92,93 is set then can to obtain following equality: Vm* (T-T0)/V=V0* (T1-T0)/V+V1* (T12-T0)/V+V2* (T23-T0)/V+V3* (T3-T0)/V according to thermal energy balance; 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, just can calculate the heat of mixing water yield Vm that can supply bathing in the inner bag in real time according to the inner bag partial volume that these water temperature value are associated.
For ease of calculating, in this embodiment, second and third temperature sensor 92,93 residing diametrically positions make the volume V 1 of winning equal second volume V 2, and first volume V, 1＞bottom volume V 0.Preferably; Can also make the first volume V 1=, the second volume V 2=top volume V 3; That is to say; Second and third temperature sensor 92,93 residing axial cross sections 17,18 are divided into three parts with the inner bag volume of first temperature sensor, 91 residing axial cross sections more than 16, and first temperature sensor, 91 residing positions can make V0/V1 be 1/3 ratio, thereby can simplify the calculating of heat of mixing water yield Vm greatly.Certainly, those skilled in the art can understandablely be that the V1 in the above-mentioned embodiment, V2, V3 are equal in theory; But possibly can't guarantee on engineering equal fully, can only make V1, V2 or V1, V2, V3 suitable, that is to say; About equally, allow and have certain deviation.In addition, what those skilled in the art can expect easily is also more temperature sensor can be set on inner bag, thereby make the calculating of heat of mixing water yield Vm more accurate.
Because the volume that position and inner bag part is set of temperature sensor is associated, thus can be in real time and calculate the interior hot water amount of inner bag comparatively exactly, to give the user reference reliably.
Cooperation is with reference to Fig. 2 and shown in Figure 3, and water heater also comprises input unit 51, display unit 52, and the controller 50 that electrically connects with input unit 51, display unit 52, heating component 20 and system for detecting temperature 90.Input unit 51 is used to supply user's control program menu, selection function, adjusting temperature etc.; In embodiment as shown in Figure 3; Input unit 51 comprises the some touch button B1-B8 that are arranged in display unit 52 bottoms; Be printed with corresponding mark on these buttons respectively, discern for the user.Display unit 52 can show corresponding programs menu according to user's control; And other is like necessary informations such as temperature, and it can be light emitting diode (Light-Emitting Diode, LED) display screen; Also can liquid crystal (Liquid Crystal Display, LCD) display screen.In this embodiment, display unit 52 is a light emitting diode (LED) display screen.Controller 50 can be embodied in the analog control circuit, digital control circuit of hardware or software and by the integrated circuit of microprocessor or microprocessor controls.In this embodiment; Controller 50 is a microprocessor; Well-known to those skilled in the artly be, microprocessor can comprise CPU (Central Processing Unit, CPU), read-only memory module (read-only memory; ROM), the arbitrary access module (random access memory, RAM), time block, digital-to-analogue conversion module (A/D converter) and some input/output end ports.These input/output end ports can be realized communicating by letter receiving data or signal and exporting control signal with input unit 51, display unit 52, heating component 20 and system for detecting temperature 90 respectively.Certainly; Controller 50 also can adopt other forms of integrated circuit; As application-specific IC (Application Specific Integrated Circuit, ASIC) or field programmable gate array (Field Programmable Gate Array, FPGA) etc.
As shown in Figure 3, in this embodiment, be printed with a humanoid mark on the button B6, be used for supplying the user to set and want the number of bathing.Respective regions 521 on display screen can show the mark of representing bather number, in this embodiment, is 4 humanoid marks.Certainly, in other embodiments, mark can be other figure or form, like the figure of shower nozzle, the figure of bathtub etc., perhaps only represents bather number through the mode that shows numerical value.Because these figures or display format are that those skilled in the art can expect easily, so the applicant no longer gives unnecessary details at this.
That shown in Figure 4 is the hot water amount that controller 50 adapts with heating according to the next corresponding control heating component 20 of the bather number of user's setting.At first, the user sets the number of wanting bathing through pushing button B6, and then controller 50 receives the setting signal (step 611) of this sign bather number through corresponding ports.For example, the user pushes button B6 No. one time, adds their confirmation through pushing the OK button then, at this moment is chosen with regard to the people who has a bathing.Correspondingly, controller 50 will receive the setting signal that characterizes people's bathing; Simultaneously, viewing area 521 can show the mark of represent bather number with first mode, becomes half brightly like first humanoid mark, and all the other are secretly, show that the people of a bathing is chosen.Likewise, can set two, three or four bather numbers.Certainly, in other embodiments, the bather number that can supply set can be more or a little less.Controller can be confirmed and the selected corresponding hot water amount's of number reservation value after receiving setting signal, controls heating component work then, next describes in detail.Whether just at work controller 50 can detect heating component 20 (step 612), if whether the hot water amount who then detects in the inner bag can supply the setting number to have a bath (step 614), promptly whether reaches the predetermined value of corresponding number; If not, then initialization to be to start heating component (step 613), then execution in step 614 next.As previously mentioned; Controller 50 can come to calculate in real time the heat of mixing water yield Vm that is in comfort temperature T that has at present in the inner bag through system for detecting temperature 90 detected water temperature value, and judges whether to reach the hot water amount's who adapts with the setting number predetermined value (step 615).For example, the bather number of setting is a man-hour, and hot water amount's predetermined value is 60 liters.Correspondingly, the bather number of setting is two, three, during four-player, and hot water amount's predetermined value is respectively 110 liters, 160 liters, 210 liters.If the hot water amount has reached the setting demand, then controller 50 can judge whether heating is also continuing (step 616), if, controller 50 control heating components quit work (step 617) then; If deny, then termination routine process (step 617).If the hot water amount does not also reach the setting demand, then controller 50 can judge equally whether heating is also continuing (step 619), if, then return step 614, promptly continue to detect the hot water amount; If not, then controller 50 starts heating component work (step 620), next returns step 614, continues to detect the hot water amount, till the hot water amount reaches the setting demand.
With reference to shown in Figure 5, controller 50 can also be according to the demonstration of detected hot water amount's real-time update display unit 52.At first, controller detects hot water amount Vm (step 620), and judging the hot water amount then with respect to whether having before increases or reduce (step 622).If the hot water amount has increase; Then controller judges whether the hot water amount reaches corresponding predetermined value (step 623) again; For example, whether hot water amount Vm reaches 60 liters of supplying people's bathing, supplies 110 liters of two people's bathings, supplies 160 liters of three people's bathings and supplies 210 liters of four people's bathings.When the hot water amount reached mutually deserved predetermined value, controller 50 control display unit 52 update displayed marks (step 625) promptly showed the mark of representing bather number with second mode.When reaching 60 liters as the hot water amount, first humanoid mark by half bright become bright entirely; Correspondingly, when the hot water amount reaches 110 liters, 160 liters, 210 liters respectively, second and third, four humanoid marks respectively by half bright become bright entirely.When the hot water amount does not also reach corresponding predetermined value, then get back to step 622, continue promptly to judge whether the hot water amount has increase or minimizing.If the hot water amount compared to before reduced, judge next then whether the hot water amount has reduced specified quantitative (step 624) from corresponding predetermined value; If then update displayed mark (step 625) promptly shows the mark of representing bather number with Third Way; If not, then get back to step 622, continue promptly to judge whether the hot water amount has increase or minimizing.In this embodiment, this specified quantitative is 10 liters.That is to say that when the hot water amount dropped to below 200 liters more than 150 liters, the 4th humanoid mark showed that by complete bright deepening the hot water that has in the inner bag supplies three people's bathings only.Correspondingly, when the hot water amount progressively drop to 150 liters, 100 liters, below 50 liters the time, the 3rd, two, a humanoid mark is progressively by complete bright deepening.
What those skilled in the art can expect easily is, first, second and third display mode in the above-mentioned embodiment can be exchanged, and can certainly adopt other display mode, like the interior zone of filling Manchu's shape mark etc.Because water heater can show the mark of represent bather number, make the user to set and want the pairing hot water amount of bather number, thereby improved the convenience of use greatly according to the demonstration of this mark; In addition, because as long as heating as required, and will not be heated to the state of full heat by the interior water of inner bag, thus avoided energy waste.
What Fig. 6 was extremely shown in Figure 9 is controller is prepared hot water in advance according to user's the bathing custom workflow schematic block diagram.Can select at least two first and second continuous cycles at this embodiment middle controller; In the period 1, write down user's use habit then; Then in second round, use this use habit, thereby the person of avoiding the use of to be provided with in advance repeatedly at every turn.In this embodiment; Cycle Length is a week, after the use habit that write down for first week, and second week and each follow-up week all can use this use habit; Only if use habit changes, can next week after changing use the use habit after changing like this.In this embodiment, the user can select this function through programs menu button B7, i.e. " intelligence weekly " function of viewing area 522 demonstrations.After this function is selected, controller 50 next will execution graph 6 to control flow shown in Figure 9.Certainly, the time span in this cycle is not limited in week, can than weak point, like day; Also can than length, like the moon, season etc.
With reference to shown in Figure 6; At first, controller 50 can be set initial first period of short period length, as ten minutes; Detect the working time (step 631) of the heating component 20 in this initial first period then, like heating component work in initial first period five minutes.Subsequently, controller 50 calculates and adds hot water amount Vh (step 632) in these periods.Usually, heating component the hot water amount that per minute can produce under rated power can record in advance, and as 2 liters/minute, same, if heating component was worked five minutes in initial first period, the hot water amount who is then produced is 10 liters.Next, controller detects in this initial first period whether hot water consumption (step 633) is arranged, i.e. interior hot water consumption Vc＞0 of initial first period whether.And Vc=when should the period initial hot water amount Vm1+ in the inner bag should be in the period hot water amount Vh-through the thermal source heating hot water amount Vm2 in the inner bag should stop the period time.In this embodiment; Vm1 and Vm2 are respectively when picking up counting initial first period and timing heat of mixing water yield in the courage when stopping; As previously mentioned, this hot water amount can calculate through the detected water temperature value of system for detecting temperature, and the applicant no longer gives unnecessary details at this.If do not have hot water consumption in initial first period, then controller is not carried out any operation (step 635).If detect in initial first period hot water consumption is arranged, then controller then judges whether it is to detect hot water consumption (step 635) for the first time, if then can note zero-time and initial hot water consumption.In this embodiment, zero-time is the timing time started of this initial first period, and the initial hot water consumption is Vc.Need to prove that in this embodiment, controller is for the first time after the water detecting, and can judge further also whether the hot water consumption surpasses a predetermined value, for example 10 liters (step 636).Because, if because special circumstances have just consumed a spot of hot water, as interim water situation such as wash one's hands, these situation do not belong to normal use habit usually, so can not need record.Therefore, if the hot water consumption does not surpass predetermined value, controller need not carried out any operation (step 636); If surpassed predetermined value, then controller can record start time and initial hot water consumption (step 636).Get back to step 634; If the hot water consumption that controller detected in this initial first period is not for the first time; Show that this initial first period is a lasting water of following last initial first period; So controller does not need the record start time again, as long as on original initial hot water consumption, add up new hot water consumption (step 636).
Because the time span of initial first period is shorter, if the time interval of hot water consumption several times is short, and each time that consumes is not long, and like this, controller just needs the frequent starting heating component to prepare hot water in second round.So; As improving further; Long initial second period of a time span can be set; This initial second period on time span at least more than or equal to two initial first periods, preferably, can with the time span of initial second period be arranged to several times to or number decuple the time span of initial first period.In this embodiment, initial first period is set to ten minutes, and initial second period is set to two hours.With reference to shown in Figure 7, controller can write down the hot water behaviour in service (step 641) of each initial second period.Concrete, controller can be set at the zero-time of first appearance in this initial second period the zero-time (step 642) of this initial second period; The initial hot water consumption of each initial first period in this initial second period is added up, as the initial hot water consumption (step 643) of this initial second period.For example, occurred the consumption of several times hot water in initial second period, the zero-time that then first time, hot water consumed is the zero-time of this initial second period of conduct just, and the total amount of several times hot water consumption accumulative total is the initial hot water consumption of this initial second period.Certainly, if hot water consumption do not occur in this initial second period, then controller can not carry out record.After the hot water behaviour in service in this initial second period record finishes, the record that then control unit end should the period and get into the record (step 644) of next initial second period.
Fig. 8 and shown in Figure 9 be controller according to the hot water behaviour in service that writes down in the period 1, two of respective application embodiments in second round then.As shown in Figure 8, controller can judge at first whether the object time has arrived (step 651).In second round; Be provided with the period 1 in corresponding the first/two period of target of initial the first/two period; Zero-time in then initial the first/two period is corresponding with the corresponding object time of target in the first/two period, and the initial hot water consumption in initial the first/two period is suitable with the corresponding target hot water consumption of target in the first/two period.Here " quite " of indication comprise equal fully, also comprise some in particular cases near equating.For example, the object time near before paroxysmal hot water consumption (like non-bathing habitually) appears and the hot water consumption that causes preparing reduces.When controller is found this situation, can in time start the hot water consumption that heating component is reduced to supply, but the time of supplementary heating is longer, when the object time arrived, the hot water consumption of preparation was not also supplied fully, and is just comparatively approaching.Also do not arrive if detect the object time, then controller is not carried out any operation (step 653).If the object time arrives, then whether next controller judge target hot water consumption sufficient (step 652), and promptly whether target hot water consumption is suitable with corresponding initial hot water consumption.If target hot water consumption is enough, then continue to judge heating component whether at work (step 654), if then controller control heating component stops heating (step 654); If then controller is not carried out any operation (step 657) not.If target hot water consumption is also not enough, then whether at work controller can judge heating component (step 655) equally, if then controller is not carried out any operation (step 657); If, then controller control heating component does not start heating (step 658).
Fig. 9 has disclosed the embodiment of Another application.In this embodiment, controller can judge whether the zero-time of current period is positioned at the second half section (step 661) of this period.The period of indication is the target first or second period here.With second period be example, judge promptly whether the zero-time in current two hours is positioned at back one hour.If then controller judges then whether the zero-time of next period is positioned at its preceding half section (step 662); If, showing that then the water in two periods is continuous or very near at interval, so,, can these two periods be merged with the follow-up hot water consumption (step 664) for preparing together for avoiding starting continually heating component.Certainly, if when time span that should the period is longer, can judge further whether the zero-time of current period is positioned at 1/4 time durations thereafter, and whether the zero-time of next period is positioned at its time durations of preceding 1/4.Be example with second period still, promptly current two hours zero-time is positioned at 30 minutes thereafter, and simultaneously, whether next two hours zero-time is positioned at its preceding 30 minutes.
If the zero-time of current period is not positioned at its second half section; Perhaps the zero-time of next period is not positioned at its preceding half section; After perhaps two periods satisfy the merging condition and merge; Whether the target hot water consumption that next controller can judge the current period sufficient (step 663), if current and the next period has merged, whether what then judge is the target hot water consumption that the adds up abundance of these two periods.If then controller is not carried out any operation (step 665); If, then controller calculating does not add the time (step 666) that thermal target hot water used in amounts will heat.As previously mentioned, heating component the hot water amount that per minute can produce under rated power can record in advance, just can calculate thus so will produce the needed time of target hot water consumption.Next controller judges whether arrived (step 667) preheating time, promptly the object time more forward in advance the target hot water used in amounts time span that will heat whether arrive.If arrived, then controller starts heating component heating (step 668); If also be less than, then controller is not carried out any operation (step 668).
Owing to set for first and second cycles; And record user's bathing custom in the period 1; Then in second round, use the bathing custom that is write down; Make the user all will repeat to be provided with the hot water of the bathing that is prepared in advance before the bathing at every turn, thereby improved the convenience that uses greatly.In the above-mentioned embodiment, period 1 and second round are continuous, but in other embodiments, these two cycles also can be discontinuous, look user's demand and decide; In addition, period 1 and second round can be isometric, like day, week etc., also can be not isometric, like the moon, and season etc.
With reference to the display unit of water heater in second embodiment of the present invention shown in Figure 10, in this embodiment, water heater provides diversified bathing kind.Shown in figure, display unit can show the mark of represent some bathing kinds, as represent adult male shower mark 531, represent the adult female shower mark 532, represent children shower mark 533, reach the shower mark 534 represent unspecified person.The particular thermal water yield during predetermined temperature that roughly needs when wherein, each mark characterizes corresponding human crowd bathing.As according to the experiment and survey data; About 50 liters of the hot water amounts that the general needs of adult male once flushing shower are 40 ℃; So, represent the shower mark 531 of adult male to characterize 50 liters 40 ℃ hot water amount, the surplus that perhaps can increase by 10 liters again is to guarantee that sufficient hot water is arranged.Correspondingly, represent adult female's shower mark 532 to characterize 100 liters 40 ℃ hot water amount, represent children's shower mark 533 to characterize 50 liters 40 ℃ hot water amount.Represent the shower mark 534 of unspecified person can be defined as the visitor, it characterizes 75 liters 40 ℃ hot water amount.Certainly, adult male, adult female and children are different to the adaptedness of water temperature, so, represent the shower mark 531 pairing predetermined temperatures of adult male also can suitably improve, as 42 ℃; And represent children's shower mark 533 pairing predetermined temperatures suitably to reduce, as 38 ℃.For ease of control; Controller 50 can be with the corresponding hot water amount that 42 ℃ of hot water amounts of 50 liters during with 38 ℃ are equivalent when becoming 40 ℃; Control heating component 20 heating according to the monitoring of system for detecting temperature 90 then, at length the course of work is with above-mentioned embodiment, and the applicant no longer gives unnecessary details at this.
In use, the user selects to want with it mark 531-534 of bathing kind through the button B6 of input unit.Controller 50 is after receiving setting signal, and control display unit 52 shows corresponding bathing kind mark, becomes partly bright like mark.Then, the user confirms to select through button B8, and next controller is controlled heating component and heated.When the hot water amount in the inner bag reached the hot water amount that selecteed bathing kind mark characterized, controller control display unit was upgraded corresponding bathing kind mark, as mark by half bright become bright entirely, thereby the expression user can begin bathing.Because the user can select to want the kind of bathing, thereby need not worry that the hot water amount is not enough in the bathing process, on the other hand, water heater can not produce unnecessary hot water amount extraly yet, and then and has avoided energy waste.
