Detailed description of the invention
Figure 1 shows that a detailed description of the invention of water heater of the present invention.For storage-type electric water heater in this enforcement, certain the present invention also can be applied to the water heater of other types, as gas heater etc.Water heater 100 comprises the inner bag 10 for storing healed water.Usually be also coated with shell (not shown) outside the tank and be formed in the thermal insulation layer (not shown) being filled with foamed material (as being made up of polyurethane material) between inner bag and shell.Inner bag 10 is roughly barrel-shaped in what extend along longitudinal axis direction, and it has drum-shaped bucket wall, is usually made up of ferrous metal, as steel, iron etc.The bottom of inner bag 10 is provided with the water inlet 81 for being introduced by cold water in inner bag and is used for discharging a delivery port 82 of healed water.The shell of water heater 100 is also provided with hanger assembly (not shown) usually, for coordinating with the support member be arranged on body of wall (not shown) so that water heater is suspended to body of wall.
Water heater 100 also includes the heating component 20 for heating cold water.In embodiment as shown in Figure 1, one first electric heating tube 21 is arranged on the first half of inner bag 10, and this heating tube is arranged on one first flange 31.First flange 31 is arranged in the axial domed ends 11 of inner bag 10.First electric heating tube 21 enters in inner bag 10 from horizontal-extending the first flange 31, and downward wriggling extends into the lower position place of the first half of inner bag 10 further.The resistance wire 211 that one has high impedance is provided with in first electric heating tube 11, this resistance wire 211 is connected with the positive and negative electrode terminal (sign) be located on the first flange 31 by wire (not shown), with the AC power conducting with 220V or 110V, thus be heat energy by electric energy conversion.Certainly, for other forms of water heater, as gas water heater, can be heated the liquid in inner bag by the combustion chamber arranged outside the tank.One second and three electric heating tubes 22,23 be jointly arranged on second flange 32, this second flange 32 is fixed on the center of the axial end portion 11 of inner bag 10.Similar to the first electric heating tube 21, second and third electric heating tube 22,23 all wriggles from the second flange 32 and extends downward the bottom of close inner bag 10, is provided with resistance wire (not shown) in it equally.Second electric heating tube 22 is also provided with a plate washer 221 at the water inlet position place of contiguous water inlet pipe 81, is used for guiding the cold water entered from water inlet and makes it transversely flow, thus the hot water layer avoiding it directly to enter being positioned at inner bag upper strata and affect the efficiency of heating surface.
Water heater 100 also comprises a system for detecting temperature 90, and it at least comprises the first temperature sensor 91, second temperature sensor 92 and three-temperature sensor 93 along the radial direction perpendicular to longitudinal axis direction distributes successively from low to high.Temperature sensor can adopt various ways, as thermistor, temperature tube etc., for detecting the water temperature of relevant position in inner bag, and be converted into the signal of telecommunication and feed back to controller 50, thus controller 50 according to the temperature information received, can decide the control (hereinafter will be described in detail) to these heating tubes.In the present embodiment, the first temperature sensor 91 is fixedly installed on the outer surface of inner bag 10 ball-shaped end 11, and this fixed form can be connected to be welded on inner bag ball-shaped end 11 outer surface has (not shown) on externally threaded cylinder.Second and three-temperature sensor 92,93 be separately fixed on the first and second flanges 31,32, and extend into the inside of inner bag 10.Certainly, in other embodiments, first, second and third temperature sensor all can be selected to be arranged on outer surface of liner or inner bag inside.
In the present embodiment, the first temperature sensor 91 is positioned at above plate washer 221 diametrically also near plate washer 221.By this set, the temperature that the first temperature sensor 91 is detected reflects the cold water layer temperature being positioned at inner bag low level substantially.Axial cross section 16 residing for first temperature sensor 91 and define a bottom volume V0 between the bottom of inner bag 10, because the volume of V0 is less, the first temperature sensor 91 can react rapidly, obtains the water temperature value T1 representing V0 soon.One first volume V1 is defined between first and second axial cross section 16,17 residing for temperature sensor 91,92; One second volume V2 is defined between second and third axial cross section 17,18 residing for temperature sensor 92,93; Axial cross section 16 residing for three-temperature sensor 93 and define a top volume V3 between the top of inner bag 10.Second and third water temperature value measured by temperature sensor 92,93 is respectively T2, T3, and wherein can represent the water temperature value of V1 part with the mean value T12 of T1 and T2, 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.
Experimentally show, a normal adult human hot water amount had required for a bath is about 50 liters; By that analogy, the hot water amount required for 2 to 4 people is respectively 100 liters, 150 liters and 200 liters.It should be noted that, the hot water amount of indication refers to pure hot water when being in bath comfort temperature T (as 40 degrees Celsius) and the heat of mixing water yield after cold water mix here.Certainly, in other embodiments, also only can add up the amount of pure hot water, and then be converted into the corresponding heat of mixing water yield.Suppose in inner bag be in temperature T 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, then 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)/V wherein V0, V1, V2, V3 is by arranging first, two, three-temperature sensor 91, 92, predefined ratio is carried out in the position of 93, and the cold water temperature T0 of comfort temperature T and water inlet is known, that is, according to the water temperature value measured by each temperature sensor, and then according to the inner bag partial volume that these water temperature value are associated, just can calculate in real time can for the heat of mixing water yield Vm of bathing in inner bag.
For ease of calculating, in present embodiment, the residing diametrically position of second and third temperature sensor 92,93 makes the first volume V1 equal the second volume V2, and the first volume V1 > bottom volume V0.Preferably, the first volume V1=second volume V2=top volume V3 can also be made, that is, the inner bag volume of the axial cross section more than 16 residing for the first temperature sensor 91 is divided into three parts by second and third axial cross section 17,18 residing for temperature sensor 92,93, and the position residing for the first temperature sensor 91 can make V0/V1 be 1/3 ratio, thus greatly can simplify the calculating of heat of mixing water yield Vm.Certainly, those skilled in the art can be understandable, and V1, V2, V3 in above-mentioned embodiment are equal in theory, but possibly cannot guarantee completely equal in engineering, V1, V2 or V1, V2, V3 can only be made quite, that is, roughly equal, allow to there is certain deviation.In addition, those skilled in the art can easily it is contemplated that also can arrange more temperature sensor on inner bag, thus 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 the hot water amount in inner bag can be calculated in real time and more adequately, to give user reliably reference.
Coordinate with reference to shown in Fig. 2 and Fig. 3, water heater also comprises input unit 51, display unit 52, and the controller 50 be electrically connected with input unit 51, display unit 52, heating component 20 and system for detecting temperature 90.Input unit 51 is for supplying user's control program menu, selection function, adjustment temperature etc., in the embodiment shown in fig. 3, input unit 51 comprises the some touch button B1-B8 be arranged in bottom display unit 52, these buttons are printed with corresponding mark respectively, identify for user.Display unit 52 can show corresponding programs menu according to the control of user, and other is as necessary informations such as temperature, it can be light emitting diode (Light-EmittingDiode, LED) display screen, also can liquid crystal (LiquidCrystalDisplay, LCD) display screen.In the present embodiment, display unit 52 is light emitting diode (LED) display screen.Controller 50 can be embodied in the analog control circuit of hardware or software, digital control circuit and the integrated circuit by microprocessor or microprocessor control.In the present embodiment, controller 50 is microprocessor, well-known to those skilled in the artly be, microprocessor can comprise CPU (CentralProcessingUnit, CPU), read-only memory module (read-onlymemory, ROM), random access module (randomaccessmemory, RAM), time block, digital-to-analogue conversion module (A/Dconverter) and some input/output end ports.These input/output end ports can realize communicating with input unit 51, display unit 52, heating component 20 and system for detecting temperature 90 respectively and receive data or signal and export control signal.Certainly, controller 50 also can adopt other forms of integrated circuit, as application-specific IC (ApplicationSpecificIntegratedCircuit, ASIC) or field programmable gate array (FieldProgrammableGateArray, FPGA) etc.
As shown in Figure 3, in present embodiment, button B6 is printed with a humanoid mark, is used for setting for user the number wanting bathing.Respective regions 521 on a display screen can show the mark representing bather number, in present embodiment, is 4 humanoid marks.Certainly, in other embodiments, mark can be other figure or form, as the figure of shower nozzle, the figure etc. of bathtub, or represents bather number by means of only the mode of display numerical value.Because these figures or display format are that those skilled in the art can expect easily, so applicant is no longer repeated at this.
Shown in Fig. 4 is that controller 50 carrys out corresponding control heating component 20 to heat the hot water amount adapted according to the bather number that user sets.First, user sets by pressing button B6 the number wanting bathing, and then controller 50 is by the setting signal (step 611) of corresponding port accepts to this sign bather number.Such as, user presses a button B6, and then added their confirmation by pressing OK button, the people at this moment just having a bathing is selected.Correspondingly, controller 50 will receive the setting signal of sign people's bathing; Meanwhile, viewing area 521 display can represent the mark of bather number in the first way, and as first man shape mark becomes half bright, all the other be dark, show that the people of a bathing is chosen.Similarly, two, three or four bather numbers can be set.Certainly, in other embodiments, can for setting bather number can be more or a little less.Controller, after receiving setting signal, can determine the reservation value of the hot water amount corresponding with selected number, then controls heating component work, is next described in detail.Whether just at work (step 612) controller 50 can detect heating component 20, if whether the hot water amount then detected in inner bag can have a bath (step 614) for setting number, namely whether reaches the predetermined value of corresponding number; If not, then initialize to start heating component (step 613), then next perform step 614.As previously mentioned, controller 50 calculates the heat of mixing water yield Vm being in comfort temperature T had at present in inner bag in real time by the water temperature value that system for detecting temperature 90 detects, and judges whether the predetermined value (step 615) reaching the hot water amount adapted with setting number.Such as, when the bather number of setting is a people, the predetermined value of hot water amount is 60 liters.Correspondingly, the bather number of setting is two, three, four people time, the predetermined value of hot water amount is respectively 110 liters, 160 liters, 210 liters.If hot water amount has reached setting demand, then controller 50 can judge that whether heating is also in continuation (step 616), if then controller 50 controls heating component and quits work (step 617); If not, then program process (step 617) is terminated.If hot water amount does not also reach setting demand, then controller 50 can judge that whether heating is also in continuation (step 619), if so, then returns step 614, namely continues to detect hot water amount equally; If not, then controller 50 starts heating component work (step 620), next returns step 614, continues to detect hot water amount, until hot water amount reaches setting demand.
With reference to shown in Fig. 5, controller 50 can also according to the display of the hot water amount's real-time update display unit 52 detected.First, controller detects hot water amount Vm (step 620), then judges hot water amount relative to whether having increase before or reducing (step 622).If hot water amount has increase, then controller judges whether hot water amount reaches corresponding predetermined value (step 623) again, such as, whether hot water amount Vm reaches for 60 liters of people's bathing, for two people's bathings 110 liters, for three people's bathings 160 liters and for 210 liters of four people's bathings.When hot water amount reaches mutually deserved predetermined value, controller 50 controls display unit 52 and upgrades show tags (step 625), and namely display represents the mark of bather number in a second manner.During as reached 60 liters as hot water amount, first man shape mark from half bright become entirely bright; Correspondingly, when hot water amount reaches 110 liters, 160 liters, 210 liters respectively, second and third, four humanoid marks respectively from half bright become entirely bright.When hot water amount does not also reach corresponding predetermined value, then get back to step 622, namely continuing to judge whether hot water amount has increases or reduces.If hot water amount is compared to decreasing before, then next judge whether hot water amount reduces specified quantitative (step 624) from corresponding predetermined value; If so, then upgrade show tags (step 625), namely represent the mark of bather number with Third Way display; If not, then get back to step 622, namely continuing to judge whether hot water amount has increases or reduces.In the present embodiment, this specified quantitative is 10 liters.That is, when hot water amount drops to less than 200 liters more than 150 liters, the 4th humanoid mark, by complete bright dimmed, shows that the hot water had in inner bag supplies three people's bathings only.Correspondingly, when hot water amount progressively drops to 150 liters, 100 liters, less than 50 liters, the 3rd, two, a humanoid mark is progressively by complete bright dimmed.
Those skilled in the art easily it is contemplated that first, second and third display mode in above-mentioned embodiment can be exchanged, can certainly adopt other display mode, as filled the interior zone etc. of Manchu's shape mark.Because water heater can show the mark representing bather number, user can be set and the hot water amount wanted corresponding to bather number according to the display of this mark, thus substantially increase the convenience of use; In addition, as long as owing to heating as required, and the state of full heat will be heated to by the water in inner bag, thus avoid energy waste.
Shown in Fig. 6 to Fig. 9 is that controller prepares the workflow schematic block diagram of hot water in advance according to the bathing custom of user.Controller can select at least two continuous print first and second cycle in the present embodiment, then within the period 1, record the use habit of user, then within second round, apply this use habit, thus avoid user all will repeatedly pre-set at every turn.In the present embodiment, Cycle Length is a week, and after have recorded the use habit of first week, second week and each follow-up week all can apply this use habit, unless use habit changes, the use habit after changing can be applied next week after changing like this.In the present embodiment, user can select this function by programs menu button B7, i.e. " weekly intelligence " function of viewing area 522 display.After this function is selected, next controller 50 will perform the control flow shown in Fig. 6 to Fig. 9.Certainly, the time span in this cycle is not limited in week, can be shorter than it, as day; Also can than length, as the moon, season etc.
With reference to shown in Fig. 6, first, controller 50 can set initial first period of short period length, as ten minutes, then the working time (step 631) of the heating component 20 in this initial first period is detected, as heating component work in initial first period five minutes.Subsequently, controller 50 calculates the heating water yield Vh (step 632) in this period.Usually, heating component the hot water amount that energy per minute produces under nominal power can record in advance, and as 2 liters/min, equally, if heating component has worked five minutes within initial first period, then produced hot water amount is 10 liters.Next, controller detects in this initial first period whether have hot water consumption (step 633), the using amount of hot water Vc > 0 namely whether in initial first period.And this period of Vc=initial time inner bag in this period of hot water amount Vm1+ in by the hot water amount Vm2 in inner bag during this period concludes of hot water amount Vh-of heat source.In the present embodiment, Vm1 and Vm2 be when starting timing initial first period respectively and timer expiration time courage in the heat of mixing water yield, as previously mentioned, the water temperature value that this hot water amount detects by system for detecting temperature and calculating, applicant is no longer repeated at this.If do not have hot water consumption in initial first period, then controller does not perform any operation (step 635).If detect in initial first period have hot water consumption, then controller then judges whether it is first time hot water consumption (step 635) detected, if so, then can record initial time and initial hot water consumption.In the present embodiment, initial time is the timing time started of this initial first period, initial hot water consumption and Vc.It should be noted that, in the present embodiment, controller detect be first time water after, also can judge that whether using amount of hot water is more than a predetermined value further, such as 10 liters (step 636).Because if just consume a small amount of hot water due to special circumstances, use regimen condition as washed one's hands etc., these situations do not belong to normal use habit usually, so can not need record temporarily.Therefore, if using amount of hot water does not exceed predetermined value, controller does not need to perform any operation (step 636); If exceeded predetermined value, then controller can record start time and initial hot water consumption (step 636).Get back to step 634, if controller detects that the hot water consumption in this initial first period is not first time, show that this initial first period is the lasting water of then last initial first period, so controller does not need the record start time again, as long as using amount of hot water (step 636) accumulative new on original initial hot water consumption.
Because the time span of initial first period is shorter, if the time interval of hot water consumption is several times short, and each time consumed is not long, and like this, controller just needs frequent starting heating component to prepare hot water within second round.So, as improving further, initial second period that a time span is longer can be set, this initial second period is at least more than or equal to two initial first periods in time span, preferably, the time span of initial second period can be arranged to times over or several times in the time span of initial first period.In the present embodiment, initial first period is set to ten minutes, and initial second period is set to two hours.With reference to shown in Fig. 7, controller can record the hot water behaviour in service (step 641) of each initial second period.Concrete, the initial time that in this initial second period, first occurs can be set as the initial time (step 642) of this initial second period by controller; 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.Such as, occurred the consumption of several times hot water in initial second period, then the initial time that consumes of hot water is just as the initial time of this initial second period first time, and the initial hot water consumption of the total amount that the consumption of several times hot water adds up initial second period that is this.Certainly, if there is not hot water consumption in this initial second period, then controller can not carry out record.After the hot water behaviour in service record in this initial second period, then controller terminates the record of this period and enters the record (step 644) of next initial second period.
Shown in Fig. 8 and Fig. 9 be controller according to the hot water behaviour in service recorded in the period 1, then two embodiments of respective application within second round.As shown in Figure 8, first controller can judge whether the object time arrives (step 651).Within second round, be provided with target the first/bis-period corresponding with initial the first/bis-period in the period 1, initial time then in initial the first/bis-period is corresponding with the object time in corresponding target the first/bis-period, and the initial hot water consumption in initial the first/bis-period is suitable with the target using amount of hot water in corresponding target the first/bis-period." quite " of indication comprises completely equal here, also comprise some in particular cases close to equal.Such as, the using amount of hot water prepared is caused to reduce in the object time near there is paroxysmal hot water consumption (as non-habitually bathing) before.Can start heating component in time to supply reduced using amount of hot water when controller finds this situation, but the time of supplementary heating is longer, when the object time arrives, the using amount of hot water of preparation is not also supplied completely, just comparatively close.If detect that the object time does not also arrive, then controller does not perform any operation (step 653).If the object time arrives, then next controller judges target using amount of hot water whether sufficient (step 652), and namely whether target using amount of hot water is suitable with corresponding initial hot water consumption.If target using amount of hot water enough, then continue to judge whether at work (step 654) heating component, if so, then controller controls heating component stopping heating (step 654); If not, then controller does not perform any operation (step 657).If target using amount of hot water is also not enough, then whether at work (step 655) controller can judge heating component equally, and if so, then controller does not perform any operation (step 657); If not, then controller controls heating component startup heating (step 658).
Fig. 9 discloses the embodiment of Another application.In the present embodiment, controller can judge whether the initial time of present period is positioned at the second half section (step 661) of this period.The period of indication is target first or second period here.For the second period, namely to judge after whether the initial time in the first two hour is positioned at one hour.If so, then controller then judges whether the initial time of next period is positioned at its first half section (step 662); If so, then show to be that continuous print or interval are very near with water in two periods, so, for avoiding starting heating component continually, these two periods can be merged and prepare using amount of hot water (step 664) together with follow-up.Certainly, if when the time span of this period is longer, can judge whether the initial time of present period is positioned at the time durations of thereafter 1/4 further, and whether the initial time of next period is positioned at its time durations of front 1/4.Still for the second period, namely the initial time of current two hours is positioned at 30 minutes thereafter, and meanwhile, whether the initial time of next two hours is positioned at its first 30 minutes.
If the initial time of present period is not positioned at its second half section, or the initial time of next period is not positioned at its first half section, or two periods meet after merging condition merges, whether sufficient (step 663) next controller can judge the target using amount of hot water of present period, if the current and next period incorporates, then what judge is whether the cumulative target using amount of hot water of these two periods is sufficient.If so, then controller does not perform any operation (step 665); If not, then controller calculates the time (step 666) of heat target using amount of hot water needs heating.As previously mentioned, the heating component hot water amount that energy per minute produces under nominal power can record, in advance so the time that will produce required for target using amount of hot water just can calculate thus.Next controller judges whether preheating time arrives (step 667), and whether namely the object time shifts to an earlier date target using amount of hot water more forward needs the time span of heating to arrive.If arrived, then controller has started heating component heating (step 668); If be also less than, then controller does not perform any operation (step 668).
Owing to setting for the first and second cycles, and within the period 1, record the bathing custom of user, within second round, then apply recorded bathing custom, user need not to be repeated before bathing to arrange to be prepared in advance the hot water of bathing at every turn, thus substantially increase the convenience of use.In above-mentioned embodiment, period 1 and second round are continuous print, but in other embodiments, these two cycles also can be discontinuous, depending on the demand of user; In addition, period 1 and second round can be isometric, as day, week etc., can be also Length discrepancy, as the moon, and season etc.
With reference to the display unit of water heater in the second embodiment of the present invention shown in Figure 10, in the present embodiment, water heater provides diversified bathing kind.As shown in FIG., display unit can show the mark representing some bathing kinds, as represent adult male shower mark 531, represent adult female shower mark 532, represent children shower mark 533 and represent unspecified person shower mark 534.Wherein, the particular thermal water yield during predetermined temperature roughly needed when each mark characterizes corresponding human group's bathing.As experimentally and survey data, the shower of adult male once flushing probably needs the hot water amount about 50 liters of 40 DEG C, so the shower mark 531 representing adult male characterizes the hot water amount of 50 liters 40 DEG C, or the surplus that can increase by 10 liters is again to guarantee having sufficient hot water.Correspondingly, the shower mark 532 representing adult female characterizes the hot water amount of 100 liters 40 DEG C, and the shower mark 533 representing children characterizes the hot water amount of 50 liters 40 DEG C.The shower mark 534 representing unspecified person can be defined as visitor, and it characterizes the hot water amount of 75 liters 40 DEG C.Certainly, adult male, adult female and the children adaptedness to water temperature is different, so the predetermined temperature of shower mark corresponding to 531 representing adult male also can suitably improve, as 42 DEG C; And the predetermined temperature of shower mark corresponding to 533 representing children can suitably reduce, as 38 DEG C.For ease of controlling, controller 50 can by 42 DEG C and when 38 DEG C the hot water amount of 50 liters equivalent become 40 DEG C time corresponding hot water amount, then control heating component 20 according to the monitoring of system for detecting temperature 90 to heat, the course of work is with above-mentioned embodiment in detail, and applicant is no longer repeated at this.
In use, user selects by the button B6 of input unit the mark 531-534 wanting bathing kind with it.Controller 50, after receiving setting signal, controls display unit 52 and shows corresponding bathing category flag, as mark becomes half bright.Then, user confirms to select by button B8, and next controller controls heating component and heat.When the hot water amount in inner bag reach characterize by the bathing category flag selected hot water amount time, controller controls display unit and upgrades corresponding bathing category flag, as mark brightly becomes entirely bright from half, thus represents that user can start bathing.Because user can select the kind wanting bathing, thus do not need to worry that hot water amount is not enough in bathing process, on the other hand, water heater also can not produce unnecessary hot water amount extraly, and then and avoids energy waste.
With reference to the 3rd embodiment of the present invention shown in Figure 11.Provide more bathing kind in present embodiment to select.Show in figure except the mark of adult male, adult female and children, display unit can also show the mark representing different bathing modes, as shower mark 551 and bath in a tub mark 552.Combination can be carried out when user uses select.Such as, user may be selected to the combination of year male sex and shower 551, at this moment, the mark representing adult male and the mark 551 representing shower are lit, controller is judged according to the mapping table of the signal received and the bathing kind prestored and predetermined temperature hot water amount, needs the hot water amount providing 50 liters 40 DEG C.And when the user of adult male thinks tub, the combination of its mark that the display screen previous generation can be made to show adult male by control button B6 and the mark 552 that represents bath in a tub is lit, thus the hot water amount of 100 liters 40 DEG C that this combination needs to provide determined by controller.Similarly, need for adult female's shower provides the hot water amount of 100 liters 40 DEG C, for children's shower provides the hot water amount of 50 liters 40 DEG C, for adult female's bath in a tub provides the hot water amount of 125 liters 40 DEG C, for children's bath in a tub provides the hot water amount of 75 liters 40 DEG C.Certainly, those skilled in the art can easily it is contemplated that the quantity of mark can reduce or increase, as only reservation represents the mark of adult male and adult female; Or introduce the mark more representing different characteristic bathing crowd, as increased the mark (mark of the elderly) of more multiple-age bracket crowd; Or introduce the mark of the different bathing mode of more representatives, as the mark of steam bath; And these marks representing different characteristic bathing crowd and the mark representing different bathing mode can combine selection, also can select separately.
As preferred embodiment, in the second embodiment and the 3rd embodiment, the priority of each bathing kind preferentially can be set.Such as, in the third embodiment, the bathing kind that family of three is selected is followed successively by with order: adult female's shower, children's bath in a tub, adult male shower.Controller meeting sequence reception comes from the setting signal of each bathing kind of input unit; Respective markers combination in display unit also can sequential illumination, is half bright state in present embodiment; Further, controller, according to setting order, judges the hot water amount 100 liters+75 liters+50 liters needing to provide 40 DEG C.When the hot water amount in inner bag is heated to 40 DEG C, 100 liters, the marker combination of adult female and shower is brightly updated to entirely bright by half, shows that the mother in family can start bathing; When 40 in inner bag, DEG C hot water amount increases again 75 liters, and the marker combination of children and bath in a tub is brightly updated to entirely bright by half, shows that the child in family can start bathing; When DEG C hot water amount of 40 in inner bag continues again increase by 50 liters, the marker combination of adult male and shower is brightly updated to entirely bright by half, shows that the father in family can start bathing.In this way, when multiple kinsfolk needs bathing, do not need the problem worrying that whether hot water amount is enough, further increase the convenience that user uses; On the other hand, do not need to make heating component continuous service because of worrying hot water amount not enough yet, and waste unnecessary electric energy.
