Based on the hardware architecture of above-mentioned water heater, the embodiment of the method for heating and controlling of water heater of the present invention is proposed.
It is an embodiment of the method for heating and controlling of water heater of the present invention, the heating control of the water heater referring to Fig. 2, Fig. 2 Method processed the following steps are included:
Step S100 determines that user uses water reliability true in the corresponding water reliability of first time period, and according to described Set the goal water consumption；
In the present embodiment, water heater can determine that user uses water reliability in some period, be characterized with water reliability User uses the probability of water heater in the period, higher with water reliability, and user uses the probability of water heater in the period It is bigger.First time period is corresponding can be according to user's being determined with waterside number in first time period, in difference with water reliability One timing of quantity of the first time period on date, it is more with waterside number, it is bigger with water reliability.
Water heater can determine that the target of user during this period of time is used with water reliability by the way that first time period is corresponding Water.Specifically, water heater will be divided into multiple reliability sections with water reliability, for example, [100%, 85%], (85%, 70%], (75%, 55%], (55%, 40%], and (40%, 0%] five go to section, each reliability section corresponding one It is a use water grade, e.g., [100%, 85%] it is corresponding with water grade be 1 grade, (85%, 70%] it is corresponding with water grade be 2 grades, (75%, 55%] it is corresponding with water grade be 3 grades, (55%, 40%] it is corresponding with water grade be 4 grades, (40%, 0%] it is corresponding With water grade be 5 grades.It is understood that it is higher with water reliability, it is with water lower grade.Each with water grade have pair The water consumption answered, water heater determining with after water reliability, determining with the reliability section where water reliability, and then according to can It is determined by degree section and uses water grade, so that the corresponding water consumption of water grade will be used as target water consumption.
Step S200 determines the corresponding target operating parameters of the water heater according to the target water consumption；
Step S300 controls the water heater and runs in the first time period according to the target operating parameters, and/ It is run before the first time period or, controlling the water heater according to the target operating parameters.
For water heater after determining target water consumption, water heater can determine the object run ginseng of water heater according to target water consumption Number.Target operating parameters include target set temperature, the in advance heating mode pair of the corresponding parameter of heating duration and water heater At least one of parameter answered.Heating mode includes discharge water heating mode and the not heating mode that discharges water.Different heated moulds Under formula, the set temperature of water heater is different, and heating duration is different in advance.For example, water heater under the heating mode that discharges water is set Determine the set temperature that temperature is greater than the not heating mode of discharging water, and the not heating mode that discharges water needs water heater to heat in advance, and discharges water It is not absolutely required to heat in advance for heating mode water heater.When the corresponding parameter of heating duration can be the heating of water heater in advance Length, heating power etc., and the corresponding parameter of heating mode can be the start and stop etc. of each heating device in water heater.
When the target water consumption of user is smaller, water heater can be used discharge water not heating mode as target heated mould Formula at this point, water heater determines set temperature according to target water consumption, then determines heating device to the heating rate of water, thus root Duration is heated in advance according to set temperature, heating rate determination.
When the target water consumption of user is larger, the heating mode that discharges water is can be used as target heating mode in water heater, At this point, water heater determines set temperature according to target water consumption and inflow temperature, to control water heater operation.
It should be noted that when target operating parameters include heating duration in advance, when water heater according to heating in advance The long runing time point for determining water heater, and when current point in time reaches runing time point, control water heater operation, thus real Existing water heater is run before first time period according to target operating parameters.When target operating parameters do not include heating in advance When long, water heater is then run according to target operating parameters in first time period, can also be run in advance before first time period, or Person runs in advance before first time period and runs within first time period.
In technical solution provided in this embodiment, water heater determine user first time period use water reliability, and User is determined in the target water consumption of first time period, so that water heater determines heat according to target water consumption according to water reliability The target operating parameters of hydrophone, and then control water heater and run in the first time period period according to target operating parameters, or Control water heater is run before the period according to target operating parameters in advance；Since user uses water can in first time period User can be characterized by degree and uses the water degree of reliability in the period, so that water heater accurately determines user according to water reliability In the period corresponding water consumption, water heater is enabled to provide suitable hot water for user, the heat for avoiding water heater from providing Dilutional hyponatremia is very few, and the computer heating control of water heater is reasonable.
Referring to Fig. 3, Fig. 3 is to determine that user is corresponding with the one of water reliability in first time period in step S100 in Fig. 2 Refined flow chart namely step S100 include:
Step S110 determines in data collection cycle the sum of first time period and with the first time period with water Quantity, wherein the date in the data collection cycle where each first time period is different；
Step S120, according to the sum with quantity and first time period with the first time period of water, determine described in User is in the corresponding water reliability of first time period.
In the present embodiment, water heater is equipped with data collection cycle, and the duration of data collection cycle can be nearest one Week, two weeks or three weeks etc..Water heater determines the sum of the not identical first time period of same date in data collection cycle, For example, when the time span of data collection cycle is one week, then data collection cycle is with 10 points of the 9 points-morning of 7 mornings The sum of first time period namely first time period is 7.Water heater can will be used when detecting user using water heater Period where water heater is associated with the water consumption of user, therefore, after obtaining multiple first time period, determination has water heater With the quantity of the first time period of water.
Water heater can be according to the determining water of sum having with the quantity and first time period of the first time period of water Reliability.For example, being stored with the quantity of first time period, the sum of first time period in water heater and between water reliability Mapping relations, water heater is after the sum for determining first time period and with the quantity with the first time period of water, Ji Kegen It is determined according to mapping relations, the sum of first time period and quantity with the first time period with water and uses water reliability.
In technical solution provided in this embodiment, water heater determines different first time on date in data collection cycle The sum of section and quantity with the first time period with water, according to the sum of first time period and with the of water The quantity of one period water reliability so that water heater according to water reliability accurately determine user at the first time The target water consumption of section.
Referring to Fig. 4, Fig. 4 is the refinement flow diagram of step S120 in Fig. 3, and the step S120 includes:
Step S121 calculates the first ratio having between the quantity of first time period and the sum of first time period with water Value；
Step S122 determines that the user uses water reliability in first time period according to first ratio.
In the present embodiment, water heater calculates the sum with the quantity and first time period with the first time period of water Between the first ratio, the first ratio characterize user in the frequency with water of first time period, the first ratio is bigger, and user is first Period it is also higher with the frequency of water.In this regard, can exist directly using the first ratio as water reliability is used to characterize user The degree of reliability of the period water.
In one embodiment, water heater was divided into multiple periods for one day, and user uses water heater in some period Afterwards, user can be influenced in next period using the probability of hot water.For example, 8 points at night of user-, 9 points of bathings at night, User can fall asleep, then 9 points at night -10 points, at night 10 points at night -11 points and 11 points at night -12 points at night, user's water Probability can reduce, therefore, if calculate at night 9. -10, need to consider period of the user at night before 9. -10 points With the influence of water.
In this regard, water heater determines the second time period earlier than first time period, second time period and first time period place Date it is different, second time period includes one or more sub- periods, for example, being 1:00am-2:00am in first time period When, second time period 0:00am-1:00am, second time period only contains a sub- period, which is 0: 00am-1:00am；It is 3:00am-4:00am in first time period, then second time period is 0:00am-3:00am, when second Between section include three sub- periods, respectively 0:00am-1:00am, 1:00am-2:00am, 2:00am-3:00am.
Water heater calculates the sum of data collection cycle neutron period and the quantity with the sub- period with water, from And the second ratio is obtained with the quantity of the sub- period of water and the sum of sub- period according to having, if second time period includes Then there are multiple second ratios in multiple sub- periods.
After obtaining the second ratio, weight corresponding with first time period setting to each sub- period.Since the time gets over Influence of the early sub- period to first time period is smaller, and therefore, the weight of more early period time is smaller namely when first Between section weight it is maximum.Water heater is again weighted each second ratio and the first ratio, obtains target ratio, should Target ratio is use water reliability of the user in first time period.
In technical solution provided in this embodiment, water heater is according to the second time period earlier than first time period to first The influence of period has accurately determined that user uses water reliability in first time period.
Referring to Fig. 5, Fig. 5 is to determine that user is corresponding another with water reliability in first time period in Fig. 2 in step S100 One refined flow chart, step S100 include:
Step S130 determines in Various types of data collection period the sum of first time period and with the first time with water The quantity of section, wherein the time span of all kinds of data collection cycles is different；
Step S140 calculates the quantity and first in every one kind data collection cycle with the first time period with water Third ratio between the sum of period；
It is corresponding reliable with water in first time period to be determined as the user by step S150 for the maximum third ratio Degree.
In the present embodiment, user is more with waterside number to the history of water heater in some period, at another Period is less with waterside number to the history of water heater, and user is recorded as a history use with water in the multiple of period Book number, for example, user goes on business in a certain week, therefore, water heater has no the use water parameter in this week.At this point, water heater into When row uses the statistics of water reliability, due to going on business user, user is caused to use water reliability inaccuracy in the period, Namely user is less than actual water reliability with water reliability in the period.
In this regard, water heater is provided with multiple data collection cycles, the time span of Various types of data collection period is different, e.g., Time span is one week, time span is two weeks, time span is three weeks etc..The last day of data collection cycle is to work as It, it is possible to understand that it is that the data of data collection cycle acquisition update as time goes by, for example, time span is one week Data collection cycle, if date where first time period is June 8, then one day that the data collection cycle time is earliest For June 1, June is changed to 9 in the schedule where first time period, then earliest one day data collection cycle time is more New is the use water parameter that the acquisition on June 9 is replaced with acquisition on June 1 by June 2 namely water heater with water parameter.
Water heater successively calculates in every a kind of data collection cycle the sum of first time period and with the first of water The quantity of period, having with the quantity of the first time period of water is data collection cycle pair divided by the sum of first time period The third ratio answered.Multiple third ratios are calculated in water heater as a result, then using maximum third ratio as user first Period corresponding water reliability.
In the present embodiment, it by the way that multiple data collection cycles are arranged, is acquired to successively calculate user in each data It is corresponding in period to use water reliability, and use water reliability to use water reliability in first time period as user for maximum, To eliminate the outgoing problem with water reliability inaccuracy for causing water heater to determine of user.
In one embodiment, water heater currently uses water grade in being determined with water reliability for first time period according to user, Thus according to currently determining user in the corresponding target water consumption of first time period with water grade.
Specifically, water heater can accurately determine user in the period when being 1 grade or 2 grades with water grade Target water consumption.In this regard, water heater will use the maximum data collection cycle of water reliability as target data collection period, thus By user, the maximum water consumption of first time period is determined as 1 grade of water reliability level in target data collection period and 2 grades right The water consumption answered.
For user when first time period water grade is 3 grades, water heater accurately determines user in the period Water consumption.In this regard, can using user first time period maximum water consumption as use the corresponding water consumption of water reliability level 3.
For user when first time period water grade is 4 grades, user can not accurately be by hot water in the water consumption of period Device determines.In this regard, said preset amount of water will be added with 3 grades of corresponding waters of water grade, said preset amount of water is amount of redundancy, is obtained with water etc. 4 corresponding water consumptions of grade.
And when being 5 grades with water grade, water heater not can determine that user in the water consumption of first time period substantially, but user is still So there is the possibility for using water, in this regard, can will be obtained plus said preset amount of water with water class 5 with the corresponding user's water of water class 4 grade The corresponding water consumption of grade.
It is above-mentioned be only it is exemplary enumerate with the corresponding water consumption of water grade, water heater can be according to user at the first time The actual used water situation of section carries out modification appropriate.
Determine it is described it is current with water grade be equal to predetermined level, by the user the corresponding history of first time period most Big water consumption is determined as target water consumption；
When determining that the current use water grade is less than predetermined level, when by user first in target data collection period Between the maximum water consumption of section be determined as target water consumption, wherein first time period uses water in the target data collection period Reliability is higher than the use water reliability of first time period in other data collection cycles；
Determine it is described it is current be greater than predetermined level with water grade when, increase target and use the water consumption of water grade using as mesh Mark water consumption, wherein the target is with water grade lower than the current use water grade and the phase between the current use water grade A poor grade.For example, target water grade is 3 grades when being currently 4 grades with water grade.
In one embodiment, water heater can also acquire middle part water temperature, to pass through the corresponding of middle part water temperature control water heater Heating device operation.Specifically, water heater includes bottom heating device and middle part heating device.Water heater can compare liner The water temperature at middle part and the size of set temperature then show hot water if the middle part water temperature of liner is less than or equal to set temperature Water temperature at the top of device is also likely to be lower than set temperature, in this regard, the heating device operation of control liner at the bottom.And water heater top Portion and bottom are equipped with heating device, but the water that temperature is higher, and the water level that density is smaller namely temperature is high is in the top of water heater Portion.If the hot water at top is since density is smaller, to the water heating at middle part at this point, the heating device operation at the top of control liner Rate is lower.In this regard, the heating device operation of water heater control liner at the bottom, so that heating device carries out the water of liner at the bottom Heating, since the water of bottom-heated can float, so that middle part and top colder water of telling somebody what one's real intentions are are deposited into bottom and middle part, That is, the heating device of water heater control bottom heats up to the water at each position in liner.And in the middle part of liner Water temperature be greater than set temperature when, show that the water temperature at the top of liner is higher, can satisfy user to the temperature requirements of hot water, at this time Heating device without controlling bottom and top is run.Water heater is according to user in the corresponding habit water consumption of current slot The set temperature for determining water heater is compared, in middle part water with set temperature further according to water temperature in the middle part of relatively stable liner When temperature is less than or equal to set temperature, start liner at the bottom heating device, is heated up with the whole water to liner.
When water temperature in the middle part of liner is greater than set temperature, water heater further judges whether water heater is in the shape that discharges water State.If water heater is in when discharging water state, water heater is exporting hot water, and water heater exports hot water, necessarily have cold water into Enter liner.In order to guarantee that output water heater that water heater can be stable, water heater can control the heating device operation at the top of liner. The middle part water temperature of liner is higher than set temperature, then shows the water temperature at the top of liner also above set temperature, water heater exports at this time Hot water can satisfy requirement of the user to water temperature.But with the lasting output of water heater hot-water, the temperature meeting of the hot water of output It gradually decreases.Due to bottom heating device to the heating rate of the water at the top of liner be less than top heating device to liner at the top of Heating rate, therefore controllable top heating device operation, so that the hot water temperature of water heater output is higher, namely make hot water Device can export the hot water for meeting user temperature demand.
In one embodiment, water heater liner is equipped with multiple heating devices.Under the initial stage that water heater discharges water, top water temperature Range of decrease degree is smaller, if heating device is run, increase top water temperature, cause temperature limiter to cut off heating device, so that water heater It is out of service, namely as the time that water heater persistently discharges water increases, the heat inputted at the top of liner is gradually reduced.In water heater It discharging water initial stage, the bottom heating device of liner at the bottom and middle part heating device in the middle part of liner are limited to the heating of top water, The heat inputted at the top of liner is less, and therefore, water heater is in the initial stage control that discharges water to the maximum top of the heating rate of top water Heating device operation, to export more heat at the top of liner to the greatest extent.In this regard, when detecting water outlet of water heater, root According to the heating rate to the water at the top of the liner of each heating device, first object heating device is determined, wherein described One target heating device is included at least to the maximum heating device of the heating rate of the water at the top of the liner；Control described first The operation of target heating device.Safe temperature is provided in water heater, water temperature is less than safe temperature, and top water temperature and peace at top When the difference of total temperature is larger, it can control to the biggish top heating device of the heating rate of top water and middle part heating device The first object heating device of composition is run；And it is being less than safe temperature when top water temperature, and top water temperature and safe temperature When difference is smaller, then the constituted to the lesser top heating device of the heating rate of top water and lower part heating device is controlled The operation of one target heating device.
Safe temperature is smaller than the corresponding limiting temperature of temperature limiter.After the operation of first object heating device, water heater is real When obtain liner current top water temperature, current top water temperature be greater than safe temperature when, then show top water temperature over-high, if after Reforwarding row first object heating device can make the operation of temperature limiter cutting heating device.
In this regard, water heater determines that the second target heating device, the second target heating device are small to the heating rate of top water In first object heating device to the heating rate of top water.First object heating device include the middle part heating device and One and when the top heating device in bottom heating device, the second target heating device includes the top heating dress It sets, alternatively, the second target heating device includes middle part heating device and bottom heating device.
After determining the second target heating device, control first object heater stop operation, and control the second target Heating device operation.
Further, after the second target heating device runs a period of time, if current top water temperature is greater than safe temperature When, then show top water temperature over-high, if continuing to run the second target heating device, the fortune of temperature limiter cutting heating device can be made Row.In this regard, water heater determines third target heating device, third target heating device is to the heating rate of top water less than second Heating rate of the target heating device to top water.It include top heating device in the second target heating device, alternatively, the second mesh Mark heating device includes middle part heating device and bottom heating device, and third target heating device includes the bottom-heated dress It sets.After determining third target heating device, control the second target heater stop operation, and control the second target heating dress Set operation.
And so on, after switching target heating device operation a period of time, current top water temperature is greater than safe temperature, heat Current goal heating device is then switched to next target heating device by hydrophone, and next target heating device is to top water Vocal print rate is less than current goal heating device to the heating rate of water.
After the operation of first object heating device, water heater can calculate the heat of water heater unit time output.Unit time The heat of output=(leaving water temperature-inflow temperature) * flow * specific heat capacity * unit time, wherein flow refers to that water heater goes out The flow of water pipe, inflow temperature can detect to obtain according to liner at the bottom temperature sensor, and leaving water temperature then can be according at the top of liner Temperature sensor detects to obtain, and specific heat capacity is the specific heat capacity of water.
Water heater calculates the heat generated the first object heating device unit time.Specifically, the heat that the unit time generates Capacity * specific heat capacity * unit time * coefficient at the top of amount=heating rate * liner, first object heating device have to middle part and bottom The water in portion heats up, and therefore, the heat that first object heating device contributes top is less than actual heat namely coefficient It is less than 1.It is defeated to be equal to or less than the water heater unit time in the heat generated when the first object heating device unit time Heat out, then top water temperature amplitude of variation is smaller, at this point, controllable first object heating device continuous service, when the The heat that one target heating device unit time generated is greater than the heat of water heater unit time output, then top water temperature has rising Trend, if the first object heating device unit time generate heat be greater than the water heater unit time output heat Duration reach target duration, then show top water temperature over-high, at this time, it may be necessary to which first object heating device is switched to the Two target heating devices.
In one embodiment, water heater combines the associated watering law with water Parameter analysis user of each period, into And the intelligent functions of water heater are realized according to watering law.Specifically, water heater, which determines that current slot is corresponding, uses water Demand, wherein the water demand amount is determined according to water reliability；The water heater is determined according to the water demand amount Target set temperature；The heating device operation of the water heater is controlled according to the target set temperature.
Specifically, water heater is provided with data collection cycle, the time span of data collection cycle can for one week, two weeks, Three weeks etc., water heater can acquire being joined with water for water heater when detecting water outlet, namely when detecting user using water heater Number includes the hot water amount that user uses water heater with water parameter, and water heater is associated with preservation with the period, is adopted with establishing data Collect the period corresponding database with water parameter and period.Water heater can be determined according to the corresponding database of data collection cycle Water demand amount of the user in any one period, one day some period that the period refers to.
Water heater obtains each period in data collection cycle, and the date where each period is different, for example, number It is 7 days according to collection period, then the period [9:00,10:00] one shares 7.Water heater determine be associated with useful water parameter when Between section, and the quantity of statistical time section, which can be considered user in period waterside number.Waterside is used in water heater calculating The ratio is defined as using water reliability, and determines where water reliability by the ratio between the several and total quantity of period Section, the corresponding water consumption in each section.For example, water heater will be divided into multiple reliability sections, example with water reliability Such as, [100%, 85%], (85%, 70%], (75%, 55%], (55%, 40%], and (40%, 0%] five go to section, Corresponding one of each reliability section water grade, e.g., corresponding [100%, 85%] with water grade is 1 grade, (85%, 70%] corresponding with water grade is 2 grades, (75%, 55%] it is corresponding with water grade be 3 grades, (55%, 40%] corresponding use water Grade be 4 grades, (40%, 0%] it is corresponding with water grade be 5 grades.It is understood that it is higher with water reliability, with water grade It is lower.Each has corresponding water consumption with water grade, and water heater is being determined with after water reliability, determines and uses water reliability institute Reliability section, and then according to reliability section determine use water grade, thus will use the corresponding water consumption of water grade as Water demand amount.
When being 1 grade or 2 grades with water grade, water heater can accurately determine user in the target water of the period Amount.In this regard, water heater is divided to different water sections for the associated water consumption of each first time period is associated with, will contain useful The upper limit value in the most water section of water is as 1 grade of water reliability level water consumption corresponding with 2 grades.
For user when first time period water grade is 3 grades, water heater accurately determines user in the period Water consumption.In this regard, can using user first time period maximum water consumption as use the corresponding water consumption of water grade 3.
For user when first time period water grade is 4 grades, user can not accurately be by hot water in the water consumption of period Device determines.In this regard, said preset amount of water will be added with 3 grades of corresponding waters of water grade, said preset amount of water is amount of redundancy, is obtained with water etc. 4 corresponding water consumptions of grade.
And when being 5 grades with water grade, water heater not can determine that user in the water consumption of first time period substantially, but user is still So there is the possibility for using water, in this regard, can will be obtained plus said preset amount of water with water class 5 with the corresponding user's water of water class 4 grade The corresponding water consumption of grade.
Water heater can determine user in the water demand amount of current slot according to water grade.
Water heater can determine the target set temperature of water heater after determining water demand amount according to water demand amount, Namely after water heater controls heating device operation by target set temperature, water heater is greater than in the hot water that current slot provides Or equal to user current slot water demand amount.Reflecting between set temperature, water demand amount is stored in water heater Relationship is penetrated, can determine set temperature thus according to water demand amount.
It should be noted that under normal circumstances, water heater inflow temperature is arranged lower, and inflow temperature is considered as one Constant, thus, it is only required to can determine set temperature according to water demand amount.But in a practical situation, the inflow temperature of water heater May be higher, if the set temperature that water heater is determined according to water demand amount, actually exportable hot water amount is greater than water heater The water demand amount of user, or much larger than the water demand amount of user, the waste of water heater energy is caused, in this regard, water heater Inflow temperature or water heater of the user when current slot uses water heater current inflow temperature and water demand amount Determine target set temperature.
Water heater be equipped with multiple water discharge modes, water discharge mode include discharge water not heating mode, discharge water heating mode and increasing Molar formula etc..Water heater has corresponding maximum hot water output in different water discharge modes.The temperature specifically, water heater will intake 5 DEG C~40 DEG C of degree is divided into N sections, 35 DEG C~45 DEG C of leaving water temperature and is divided into N sections, and 35 DEG C~80 DEG C of temperature of setting is divided into N sections, out water temperature For degree at 35 DEG C~45 DEG C, water heater output is hot water；Different inflow temperatures is arranged under different heating mode in water heater And setting temperature, and output quantity of the leaving water temperature at 35 DEG C~45 DEG C is acquired, which is that water discharge mode is corresponding most Big hot water output.Water heater is according to the data between maximum hot water output, inflow temperature, setting temperature and water discharge mode Relationship constructs mapping table, and water heater is only needed can be in mapping relations according to water discharge mode, inflow temperature and set temperature Maximum hot water output is found in table.It should be noted that water heater determines setting temperature used by maximum hot water output Degree refers to the corresponding current set temperature of water heater current slot.
Water heater compares water demand amount and maximum heat after determining the corresponding maximum hot water output of each water discharge mode Water output quantity will be greater than the corresponding water discharge mode of maximum hot water output of water demand amount as target water discharge mode.Hot water Device according to the corresponding maximum hot water output of target water discharge mode, target water discharge mode and inflow temperature in mapping table Middle lookup set temperature, the set temperature are target set temperature.
The water discharge mode that maximum hot water output is greater than the water demand amount of user can be used as target water discharge mode, but most When difference between big hot water output and water demand amount is larger, the hot water for showing that water heater provides is more, water heater waste Energy it is more.In this regard, water heater first judges whether the maximum lesser water discharge mode of hot water output is target water discharge mode, then Judge whether the maximum biggish water discharge mode of hot water output is target water discharge mode, so that water heater is the hot water that user provides It will not be excessive.
It discharges water under not heating mode, the corresponding maximum hot water output of water heater is minimum, and therefore, water heater first judges to discharge water Whether the corresponding maximum hot water output of heating mode is not greater than water demand amount, if so, the not heating mode conduct that will discharge water Target water discharge mode.
If the corresponding maximum hot water output of the not heating mode that discharges water is less than or equal to the water demand amount of user, hot water Whether the device corresponding maximum hot water output of heating mode that judges to discharge water again is greater than water demand amount, and the heating mode that discharges water is corresponding Maximum hot water output is greater than the corresponding maximum hot water output of the not heating mode that discharges water, if under the heating mode that discharges water it is corresponding most When big hot water output is greater than water demand amount, then the heating mode that will discharge water is as target water discharge mode.
If the corresponding maximum hot water output of the heating mode that discharges water is less than or equal to the water demand amount of user, water heater By increase-volume mode target water discharge mode the most, the corresponding maximum hot water output of increase-volume mode is the maximum in three kinds of water discharge modes , increase-volume mode refers to that water heater acquires other means and increases hot water output, for example, being arranged in including water heater spare Heating device starts spare heating device when water heater enters increase-volume mode.
When water heater is in the state that discharges water namely water heater is used by a user, water heater has exported a part Hot water, at this point, hot water needs to redefine set temperature, so that the hot water amount of water heater residue output and the hot water amount exported The equal to or slightly larger than water demand amount of user.
In this regard, water heater in discharge water state when, the output quantity of hot water, the output quantity of hot water in real-time detection water heater Hot water amount is as exported, water heater is calculating water demand amount and exporting the difference between hot water amount, which is surplus Remaining water consumption, water heater acquisition detects inflow temperature with the temperature sensor of liner at the bottom by setting, according to inflow temperature, residue Target water discharge mode difference set temperature in mapping table, the set temperature determined by before water consumption and water heater The as current set temperature of water heater, water heater control heating device according to current set temperature, so that water heater Energy dissipation is less.
In one embodiment, water heater combines the associated watering law with water Parameter analysis user of each period, into And the intelligent functions of water heater are realized according to watering law.For example, water heater acquisition user is corresponding in first time period First uses water parameter, wherein described first uses coolant-temperature gage including the first water consumption and first with water parameter；According to described first With water parameter and the heating power of water heater, determine that the water heater heats in advance in the corresponding target of the first time period Duration；The heating device operation that duration controls the water heater is heated in advance according to the target.
Specifically, first includes the first water consumption with water parameter, first, which may also comprise first with water parameter, uses coolant-temperature gage, the One with coolant-temperature gage is temperature of the user in the required hot water of first time period, and first can be according to user first with coolant-temperature gage The habit of period is determined with coolant-temperature gage.
Specifically, first can be considered hot water with coolant-temperature gage, first can be also considered as with coolant-temperature gage the temperature for defining hot water, First use coolant-temperature gage can be 35 DEG C~45 DEG C.Water heater is determining first with after water parameter, water parameter can be used true according to first After the target set temperature namely water heater for determining water heater control heating device operation by target set temperature, water heater exists The hot water that first time period provides is greater than or equal to user in the hot water amount of current slot.Setting temperature is stored in water heater Degree, the first water consumption, first, can with coolant-temperature gage thus according to the first water consumption and first with the mapping relations between coolant-temperature gage Determine set temperature.It should be noted that under normal circumstances, lower, inflow temperature view is arranged in inflow temperature by water heater For a constant, thus, it is only required to can determine set temperature according to water consumption and with coolant-temperature gage.But it is in a practical situation, hot The inflow temperature of hydrophone may be higher, if the set temperature that water heater is determined according to water consumption, water heater are actually exportable Hot water amount is greater than the water consumption of user, or much larger than the water consumption of user, causes the waste of water heater energy, in this regard, hot water Inflow temperature or water heater current inflow temperature of the device user when current slot uses water heater, with coolant-temperature gage and Water consumption determines target set temperature.
Since water heater heats in advance, it can be considered that water heater is not intake, water heater obtains the water in liner Temperature, the water temperature can be average temperature in liner.Temperature sensor is arranged in the bottom of liner and top, passes through two temperature sensing The water temperature of device detection calculates the water temperature that average value is liner, and certainly, liner may also set up multiple temperature sensors, multiple temperature The corresponding average temperature of water temperature of sensor acquisition is liner water temperature.
Water heater is when determining target set temperature, heating device to the heating rate and liner water temperature of water, Ji Keji Calculation obtains the heating duration in advance of water heater, this heat in advance duration can heat be set to target and heat duration in advance.
Calculated after target heats duration in advance in water heater, water heater can according to first time period at the beginning of put with And target heats duration in advance and obtains the starting time point of heating device, and then when current point in time reaches starting time point, Control heating device operation.It should be noted that multiple heating devices can be set in water heater, such as 2 or 3, in heat When hydrophone is run in advance, water heater need to control each heating device operation.
Water heater first determines that first time period is corresponding with second time period and heats duration in advance, and second time period is positioned at the After one period, and it is upper adjacent with the first time period time.
Water heater calculate again put at the beginning of first time period and second time period at the beginning of between point first It is spaced duration, if the first interval duration heats duration more than or equal to second in advance, then shows user in second time period Will affect user with water and use water in first time period, in this regard, water heater calculates corresponding first water consumption of first time period Third water parameter corresponding with second time period, third water parameter include the total with water of first time period and second time period Amount, or be use of the user in first time period and second time period with coolant-temperature gage including water total amount and with coolant-temperature gage Coolant-temperature gage determines that the corresponding target of first time period heats duration in advance with water parameter according to third, so that water heater is One period and second time period can provide sufficient hot water for user.
And first interval duration less than second in advance heat duration when, then show user second time period with water not It will affect user and use water in first time period, at this point, shifting to an earlier date using the corresponding duration of heating in advance of first time period as target Heat duration.
When the first interval duration duration of heating in advance corresponding greater than second time period, water heater can be used according to first Water parameter determines that the target heating duration of first time period namely the target of second time period heat in advance with water parameter with second Duration is the first interval duration actually heats duration plus the corresponding target of first time period in advance, at this time without repeating to determine The target of second time period heats duration in advance.In this regard, when water heater determines that the target of first time period heats duration in advance, It needs to be determined that whether water heater determines first time period mesh corresponding with the third period before being located at first time period simultaneously Mark heating duration, third period are upper adjacent with the first time period time.In this regard, at the beginning of water heater calculates the third period Between point with first time period at the beginning of the second interval duration for putting, if the second interval duration is greater than first when heating in advance It is long, then it can determine that water heater does not determine that the target of first time period heats duration in advance in advance, then it needs to be determined that at the first time The target of section heats duration in advance.It is less than or equal to first in the second interval duration and heats duration in advance, then can determine that water heater Determine that the target of first time period heats duration in advance in advance, water heater can heat in advance duration according to the target of third period Determine that the corresponding target of first time period heats duration in advance namely the target of third period heats duration plus second in advance The target of a length of first time period heats duration in advance when interval.
In one embodiment, water heater combines the associated watering law with water Parameter analysis user of each period, into And the intelligent functions of water heater are realized according to watering law.For example, water heater obtains in current data collection cycle First sum of first time period, wherein each first time period belongs to the different dates；By the first time period First sum is divided into multiple set of computations according to different preset interval number of days；Calculate each set of computations first can with water By degree；Determine whether the current data collection cycle is effective with water reliability according to the first of multiple set of computations.
Specifically, water heater, which can acquire user, uses water parameter using water heater, and learned according to self is carried out with water parameter It practises, to analyze user to the laws of use of water heater, laws of use is the watering law of user, and watering law refers to using Family needed to use water in some period, or did not needed to use water in some period.
A period water of the user in some day, in this period when next day and unused water namely user First time period exist fluctuate, if fluctuation is larger, then can be shown that user the period do not have watering law namely this Data collection cycle is invalid in this period.
Specifically, water heater is needing first to judge whether some period in data collection cycle is effectively, if having Effect then shows that user is smaller in being moved with ripples for this period, and data collection cycle is that user is accustomed to the period namely user exists The period has watering law；If invalid, show that user is larger in being moved with ripples for the period, user is in the period Have no watering law.Specifically, water heater obtains data collection cycle so that the time span of data collection cycle is 7 days as an example In not same date first time period, the first sum of first time period is 7.
It is respectively 1 day, 2 days, 3 days, 4 days, 5 days .N-1 days 6 days ... that water heater takes different preset interval number of days K, K again, N is the number of days of data collection cycle namely data collection cycle includes N number of first time period, and in the present embodiment, water heater can be with Appoint in .N-1 days from 1 day, 2 days, 3 days, 4 days, 5 days, 6 days ... and take two or more preset interval number of days, to obtain corresponding number Set of computations, for example, the quantity of preset interval number of days be 3, then have 3 set of computations.It is temporally adjacent in set of computations Interval duration between first time period is preset interval number of days.For example, data collection cycle is 7 days, preset interval number of days It respectively 1 day and 2 days, then preset interval number of days is to contain 7 first time period in 1 day corresponding set of computations, presets Being spaced number of days is 4 first time period in 2 days corresponding set of computations containing 1,3,5,7.The preset interval number of days of use is got over More, whether effective data collection cycle accuracy be higher.In addition, can be to the number of the first time period in each set of computations Amount is defined, and the quantity of the first time period in set of computations is greater than or equal to preset quantity, avoids sample in set of computations The very few situation for causing error larger of quantity occurs, and preset quantity can be any appropriate numerical value.
After determining set of computations, calculate each set of computations first uses water reliability, calculates collection specifically, determining The second sum of first time period and the quantity with the first time period with water, have the first time period for using water in conjunction Quantity is the first use water reliability divided by the ratio that the second sum obtains.
Water heater determines that maximum first is reliable with water after determining that each set of computations corresponding first uses water reliability Degree using as target water reliability, then successively calculate target water reliability and it is each other first between water reliabilitys First difference, and will be greater than the first difference of preset difference value as target difference, so that it is determined that the quantity of target difference；Water heater The first ratio of the quantity of target difference and the sum of the first difference is calculated again, if the first ratio is greater than the first preset threshold, First preset threshold can be any appropriate numerical value, such as 70%, then show being moved with ripples in tolerance interval for user, namely Fluctuation is normal, determines that data collection cycle is effective at this time, which is that user is accustomed to the period；If the first ratio is less than Or be equal to the first preset threshold, then show that being moved with ripples for user is abnormal, data collection cycle is invalid namely user is in the number Watering law is had no according to the first time period in collection period.
It should be noted that settable multiple data collection cycles, the time of each data collection cycle are long in water heater Degree is different, when the current data collection cycle of determination is invalid, acquires next data collection cycle as current data Period, until determining effective data collection cycle.Certainly, if all data collection cycles are invalid, show that user exists First time period does not have watering law.
Water heater can calculate the very poor and average value of the first use water reliability of each set of computations, thus according to very poor And average value determines user's whether normally being moved with ripples in first time period, namely judges whether data collection cycle has Effect.
Specifically, water heater extracts maximum first with water reliability and the smallest water reliability to be calculated the Two differences, then each first is calculated with the corresponding average value of water reliability.Water heater is calculated again between the second difference and average value The second ratio, then judge whether the second ratio is less than or equal to the second preset threshold, the second preset threshold can be any appropriate Numerical value, such as 150%.It is being less than or equal to the second preset threshold when the second ratio, then is can determine that user in first time period It is dynamic normal namely data collection cycle is effective with ripples；If the second ratio be greater than the second preset threshold, data collection cycle without Effect.
In one embodiment, water heater combines the associated watering law with water Parameter analysis user of each period, into And the intelligent functions of water heater are realized according to watering law.For example, water heater is determining that user is not necessarily in first time period With water, the first time period corresponding water reliability and inflow temperature are obtained；Water reliability and institute are used according to described State the target set temperature that inflow temperature determines water heater.
Specifically, water heater determines the corresponding current water grade of water reliability, wherein described to use water reliability It is bigger, it is described current with water lower grade；According to the current water grade temperature incremental value, wherein the current use Water lower grade, and the temperature increment value is smaller；Water heater is determined according to the temperature increment value and the inflow temperature Target set temperature.
If be currently 1 grade with water grade, then show that user does not use the accuracy pole of water heater in first time period Height, therefore, it is inflow temperature that target can be arranged to temperature setting, and inflow temperature is the history that water heater is stored in first time period Inflow temperature.If be currently 2 grades with water grade, it is higher without using the accuracy of water heater to show that user has, at this time by target It is set as inflow temperature+temperature increment value m.And so on, when currently with water higher grade, water heater determines that user exists First time period is lower without using the accuracy of water heater, and target set temperature is higher, and target set temperature can be by following formula It determines, specifically: target set temperature=inflow temperature+K* temperature increment value, wherein K=0,1,2,3 ... .. are reliable with water Spend grade determine K size, when with water reliability level be 1 grade when, K=0, with water reliability level be 2 grades when, K= 1, and so on.
For water heater after determining target set temperature, water heater can determine the first mesh of water heater according to target set temperature Mark operating parameter.
