The primary solutions of the embodiment of the present invention are: determining that user is not necessarily in first time period with water, described in acquisition First time period is corresponding to use water reliability and inflow temperature；It is determined according to described with water reliability and the inflow temperature The target set temperature of water heater.

Since user is when without with water, water heater determines that user is not necessarily to the accuracy with water according to water reliability, into And according to accuracy and inflow temperature reasonably determine water heater set temperature, to avoid water heater waste energy compared with More, the computer heating control of water heater is reasonable.

It can be as shown in Figure 1 as a kind of implementation water heater.

For the embodiment of the present invention what is involved is water heater, water heater includes: processor 101, such as CPU, memory 102, communication bus 103.Wherein, communication bus 103 is for realizing the connection communication between these components.

Memory 102 can be high speed RAM memory, be also possible to stable memory (non- ), such as magnetic disk storage volatilememory.As shown in Figure 1, as in a kind of memory 103 of computer storage medium It may include the computer heating control program of water heater；And processor 101 can be used for calling the water heater stored in memory 102 Computer heating control program, and execute following operation:

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 S10 is determining that user is not necessarily in first time period with water, and obtaining that the first time period is corresponding can with water By degree and inflow temperature；

In the present embodiment, when using water heater, water heater can acquire user and use water parameter using water heater user, And it will be associated with user using the period of water heater with water parameter.Water heater is joined according to period and period association water Number, determines whether user needs to use water in first time period.Specifically, water heater is equipped with data collection cycle, water heater is obtained Not each first time period of same date in data collection cycle, for example, data collection cycle is 49 days, then having 49 the One period.Since user is when using water heater, by the period and water parameter association can be used, therefore, water heater can determine It is associated with the quantity of the first time period of useful water parameter, if quantity is more, then shows that user uses hot water in first time period The Probability maximum of device, water heater determine that user needs to use water in first time period；If negligible amounts, show user at first Between section using water heater probability it is lower, water heater determine user do not need to use water in first time period.Certainly, pass can also be passed through The comparison of the ratio and default ratio that are combined between the quantity of first time period and the total quantity of first time period of water parameter, with Determine whether user needs to use water in first time period.

Step S20, according to the target set temperature for determining water heater with water reliability and the inflow temperature.

Although water heater determines that user does not need to use water in first time period, there are the feelings that user may use water heater Condition, therefore, water heater can determine user in first time period without using heat in first time period according to user with water reliability The accuracy of hydrophone, higher with water reliability, user is bigger without using the probability of water heater in the period.Therefore, with water It, can be directly using inflow temperature as target set temperature, when lower with water reliability, then in water inlet temperature when reliability is higher Increased on the basis of degree to obtain target set temperature.

In technical solution provided in this embodiment, water heater is determining user when being not necessarily to water the period, and acquisition is used Water reliability and inflow temperature are used first time period in family, to determine water heater according to inflow temperature and with water reliability Set temperature；For user when without with water, water heater determines that user is not necessarily to the accuracy with water according to water reliability, in turn The set temperature of water heater is reasonably determined according to accuracy and inflow temperature, the energy to avoid water heater waste is more, The computer heating control of water heater is reasonable.

Referring to Fig. 3, Fig. 3 is the refinement flow diagram of step S20 in Fig. 2, and the step S20 includes:

Step S21 determines the corresponding current water grade of water reliability, wherein it is described bigger with water reliability, It is described current with water lower grade；

Step S22, according to the current water grade temperature incremental value, wherein it is described current with water lower grade, The temperature increment value is smaller；

Step S23 determines the target set temperature of water heater according to the temperature increment value and the inflow temperature.

After water heater determines and uses water reliability, then determine with the reliability section where water reliability to determine current use Water grade.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, water is used in corresponding one of each reliability section 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%] corresponding with water grade is 3 grades, (55%, 40%] it is corresponding with water grade be 4 grades, (40%, 0%] corresponding use water Grade is 5 grades.If be currently 1 grade with water grade, then show that user does not use the accuracy of water heater in first time period High, therefore, it is inflow temperature that target can be arranged to temperature setting, and inflow temperature is that water heater is gone through what first time period stored History 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 mesh Mark is set as inflow temperature+temperature increment value m.And so on, when currently with water higher grade, water heater determines user Lower without using the accuracy of water heater in first time period, target set temperature is higher, and target set temperature can be by following public affairs Formula is determining, specifically: target set temperature=inflow temperature+K* temperature increment value, wherein K=0,1,2,3 ... .., it can with water By degree 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.Above-mentioned is only exemplary to enumerate target set temperature and with the relationship between water reliability level, hot water Device can modify according to the actual situation.

In the present embodiment, water heater is being determined with after water reliability, currently uses water grade according to being determined with water reliability, Probability of the user in first time period without using water heater currently is determined with water grade with basis, and then according to probability and water inlet Temperature determines the target set temperature of water heater, and the intelligence degree of water heater is higher.

Referring to Fig. 4, Fig. 4 is another embodiment of the method for heating and controlling of water heater of the present invention, after the step S20, Further include:

Step S30 determines the water heater first object operating parameter according to the target set temperature；

Step S40 controls the water heater and runs in the first time period according to the first object operating parameter, And/or it controls the water heater and is run before the first time period according to the first object operating parameter.

In the present embodiment, after determining target set temperature, water heater can determine water heater according to target set temperature The first object operating parameter of water heater.First object operating parameter includes heating the corresponding parameter of duration and hot water in advance At least one of corresponding parameter of the heating mode of device.Heating mode includes discharge water heating mode and the not heated mould that discharges water Formula.Under different heating modes, it is different that duration is heated in advance.For example, the not heating mode that discharges water needs water heater to heat in advance, and Discharging water, it is not absolutely required to heat in advance for heating mode water heater.The corresponding parameter of heating duration can be the heating of water heater in advance Duration, heating power etc., and the corresponding parameter of heating mode can be the start and stop etc. of each heating device in water heater.

It should be noted that when first object operating parameter include in advance heat duration when, water heater according in advance add Hot duration determines the runing time point of water heater, and when current point in time reaches runing time point, control water heater operation, from And it realizes water heater and is run before first time period according to first object operating parameter.It is not wrapped when first object operating parameter When including heating duration in advance, water heater is then run according to first object operating parameter in first time period, can also be at the first time It is run in advance before section, or runs before first time period and run within first time period in advance.

In technical solution provided in this embodiment, water heater is after determining target set temperature, according to goal-setting temperature The target operating parameters for determining water heater are spent, so that water heater is run in the period according to target operating parameters, alternatively, making heat Hydrophone is run before the period according to target operating parameters in advance；Due to water heater can accurately determine user this when Between section be not necessarily to use water, thus avoid water heater waste energy it is more, the computer heating control of water heater is reasonable.

Referring to Fig. 5, Fig. 5 is the refinement flow diagram of step S10 in Fig. 2, and the step S10 includes:

Step S11 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 S12 determines the use according to the sum with quantity and first time period with the first time period of water Family 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 accurately determines target set temperature according to water reliability.

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 Being not necessarily to for period is higher with the accuracy of water.In this regard, can be directly using the first ratio as water reliability is used, to characterize user The degree of reliability with water is not required in the period.

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.

In one embodiment, determining that user needs that it is corresponding to obtain the first time period with water in first time period With water reliability；It is determined according to the target water consumption for determining the first time period with water reliability, and according to target water consumption Second target operating parameters of water heater, then control the water heater and transported in the first time period according to second target The operation of row parameter, and/or, it controls the water heater and is transported before the second time period according to the first object operating parameter Row.

It with water reliability and currently can refer to foregoing description with water grade in the present embodiment, no longer go to live in the household of one's in-laws on getting married one by one herein It states.

Water heater currently uses water grade in being determined with water reliability for first time period according to user, to be used according to current Water grade determines user in the corresponding target water consumption of first time period.Specifically, when being 1 grade or 2 grades with water grade, heat Hydrophone can accurately determine user in the water consumption of the period.In this regard, water heater is maximum pre- in time span by user If it is 1 grade or 2 grades of corresponding water consumptions that the maximum water consumption of first time period, which is used as with water grade, in data collection cycle.It needs Illustrate, when judging whether target data collection period is effective, water heater is by set each in the statistical data collection period The quantity of middle first time period, the set that will be greater than preset quantity are defined as effectively gathering, namely the sample data in set Quantity need be greater than preset quantity；Since user does not have watering law in first time period, then each data acquisition week Phase is calculated the quantity of corresponding efficient set by water heater, and water heater determines the most data collection cycle of efficient set.And The time span of data collection cycle is bigger, and the set of data collection cycle is more, then efficient set is also more, in this regard, Water heater is when it is 1 grade and 2 grades that subsequent determination is with water grade, directly by user in the maximum data collection cycle of time span It is 1 grade of water consumption corresponding with 2 grades that the maximum water consumption of first time period, which is used as with water grade,.

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 where maximum water consumption of the user in first time period use the upper limit value of water gear as with water can The corresponding water consumption of grade 3.For example, water heater can will be divided into five grades, respectively N1 grades: (0, Y), N2 grades: (Y, Y+ with water gear M), N3 grades: (Y+m, Y+2m), N4 grades: (Y+2m, Y+3m) and N5 grades: (Y+3m, Y+4m).Y and m is any definite value for closing number, If user is when it is 3 grades that first time period is with water grade, and maximum water consumption is Y+2.5m, then user is in first time period Target water consumption be Y+3m.

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 be greater than predetermined level with water grade, increase target and use the water consumption of water grade using as target Water consumption, wherein the target current current is differed with water grade and with described with water grade lower than described between water grade One grade.For example, target water grade is 3 grades when being currently 4 grades with water grade.

In addition, whether water heater to may determine that data collection cycle effective, it, can be accurate if data collection cycle is effective Judge whether user needs to use water in first time period.Specifically, the time span of data collection cycle is certain, for example, one week, Two weeks, three weeks etc..Water heater determines the sum that first time period is determined in data collection cycle.Water heater takes different pre- again If being spaced number of days K, K is respectively 1 day, 2 days, 3 days, 4 days, 5 days .N-1 days 6 days ..., and 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 from 1 day, 2 days, 3 days, 4 days, 5 days, 6 It ... appoint in .N-1 days and take two or more preset interval number of days, to obtain the set of computations of corresponding number, for example, preset interval The quantity of number of days is 3, then has 3 set of computations.Interval duration in set of computations between temporally adjacent first time period As preset interval number of days.For example, data collection cycle is 7 days, preset interval number of days is respectively 1 day and 2 days, then default Being spaced number of days is to contain 7 first time period in 1 day corresponding set of computations, and preset interval number of days is 2 days corresponding calculating collection In conjunction containing 1,3,5,74 first time period.The preset interval number of days of use is more, and whether data collection cycle is effective Accuracy is higher.In addition, can be defined to the quantity of the first time period in each set of computations, in set of computations The quantity of one period is greater than or equal to preset quantity, avoids the very few situation for causing error larger of sample size in set of computations Occur, preset quantity can be any appropriate numerical value.After determining set of computations, calculate each set of computations first uses water Reliability, specifically, the second sum and the number with the first time period with water that determine first time period in set of computations Amount, having with the quantity of the first time period of water is the first use water reliability divided by the ratio that the second sum obtains.Water heater After determining that each set of computations corresponding first uses water reliability, determine that maximum first uses water reliability to use as target Water reliability, then the first difference between target water reliability and other each the first use water reliabilitys is successively calculated, and will Greater than preset difference value the first difference as target difference, so that it is determined that the quantity of target difference；Water heater calculates goal discrepancy again First ratio of the sum of the quantity of value and the first difference, if the first ratio is greater than the first preset threshold, the first preset threshold It can be any appropriate numerical value, such as 70%, then show that being moved with ripples for user is normal in tolerance interval, namely fluctuation, this When determine data collection cycle it is effective.

In addition, water heater can calculate the very poor and average value of the first use water reliability of each set of computations, thus root It is whether normal in being moved with ripples for first time period that user is determined according to very poor and average value, namely judges that data collection cycle is It is no effective.

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.

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.

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 determines that user is corresponding in first time period With water reliability, and target water consumption is determined with water reliability according to described；According to the target water consumption, the hot water is determined The corresponding target operating parameters of device；The water heater is controlled to run in the first time period according to the target operating parameters, And/or it controls the water heater and is run before the first time period according to the target operating parameters.

Specifically, water heater can determine that user uses water reliability in some period, with water reliability, characterization user exists The period uses the probability of water heater, higher with water reliability, and user is bigger using the probability of water heater in the period.The One period it is corresponding can be according to user's being determined with waterside number in first time period, the of not same date with water reliability One timing of quantity of one period, it is more with waterside number, it is bigger with water reliability.Water heater is after determination water reliability, really Surely the reliability section where water reliability is used, and then is determined according to reliability section and uses water grade, so that water grade pair will be used The water consumption answered is as target water consumption.

Water heater is equipped with data collection cycle, and the duration of data collection cycle can be nearest one week, two weeks or three Week etc..Water heater determines the sum of the not identical first time period of same date in data collection cycle, for example, data acquisition week When the time span of phase is one week, then data collection cycle has 7 mornings, the 9 points-morning, 10 points of first time period, namely The sum of first time period is 7.Water heater can will use the time where water heater when detecting user using water heater Section is associated with the water consumption of user, therefore, water heater determines the first time period having with water after obtaining multiple first time period Quantity.

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.Hot water Device calculates the first ratio having between the quantity of first time period and the sum of first time period with water, the first ratio characterization For user in the frequency with water of first time period, the first ratio is bigger, and user also gets in the frequency with water of first time period It is high.In this regard, can be directly using the first ratio as water reliability is used, to characterize user in the degree of reliability of the period water.

Water heater was divided into multiple periods for one day, and user is after some period is using water heater, and user is next A period can be influenced using the probability of hot water.For example, 9 points of bathings, user's 8 points at night of user-can fall asleep at night, that 9 points at night -10 points, at night 10 points at night -11 points and 11 points at night -12 points at night, the probability of user's water can reduce, Therefore, if calculate at night 9. -10, need to consider the influence of period water of the user at night before 9. -10 points.

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.

User is more with waterside number to the history of water heater in some period, in another period to water heater History it is less with waterside number, user is recorded as a history book number with water in the multiple of period, for example, with Family is gone on business in a certain week, and therefore, water heater has no the use water parameter in this week.At this point, water heater is being carried out with water reliability When statistics, due to going on business user, cause user in the period when using water reliability inaccuracy namely user at this Between section with water reliability be less than it is actual use water reliability.

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 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.
