Based on the hardware architecture of above-mentioned water heater, the embodiment of the control method of water heater of the present invention is proposed.
It is the first embodiment of the control method of water heater of the present invention, the control method of the water heater referring to Fig. 2, Fig. 2 The following steps are included:
Step S100 obtains user in first time period corresponding first and uses water parameter, wherein described first uses water parameter Including the coolant-temperature gage of the first water consumption and first, first water consumption is determined according to water reliability；
In the present embodiment, 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 the use of water heater when detecting water outlet, namely when detecting user using water heater Water parameter includes the hot water amount that user uses water heater with water parameter, and water heater is associated with preservation with the period, to establish number According to the corresponding database with water parameter and period of collection period.Water heater can be according to the corresponding database of data collection cycle User is determined in the water consumption of any one period, one day some period that the period refers to.
Water heater obtains each first time period in data collection cycle, and the date where each first time period is not Together, for example, data collection cycle is 7 days, then first time period [9:00,10:00] one shares 7.Water heater determines association The first time period of useful water parameter, and the quantity of first time period is counted, which can be considered user in the first time period With waterside number.Ratio of the water heater calculating between waterside number and the total quantity of first time period, which is defined as using Water reliability, and determine with the section where water reliability, the corresponding water consumption in each section.For example, water heater will It is 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, corresponding one of each reliability section water grade, e.g., [100%, 85%] corresponding with water grade is 1 grade, (85%, 70%] it is corresponding with water grade be 2 grades, (75%, 55%] corresponding use 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 can manage Solution, it is higher with water reliability, it is with water lower grade.Each has corresponding water consumption with water grade, and water heater is true Surely after using water reliability, the reliability section used where water reliability is determined, and then determine according to reliability section and use water grade, To which the corresponding water consumption of water grade will be used as the first water consumption.
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.
It should be noted that first includes the first water consumption with water parameter, first, which may also comprise first with water parameter, uses water Temperature, first with coolant-temperature gage is temperature of the user in the required hot water of first time period, first with coolant-temperature gage can according to Family is determined in the habit coolant-temperature gage of first time period.
Step S200 determines the water heater described according to described first with the heating power of water parameter and water heater The corresponding target of first time period heats duration in advance；
In the present embodiment, water heater can control heating device operation in advance, use heat in first time period as user When hydrophone, water heater is enabled to provide sufficient hot water for user in advance.Water heater can be determined according to first with water parameter The target set temperature of water heater, and then according to the heating of water temperature and heating device to water in target set temperature, liner Rate calculations obtain target and heat duration in advance, heating device to the heating rate of water can according to the heating power of water heater and The calculation of capacity of liner obtains.It should be noted that the heating power of water heater can be maximum heating power, it can also be optimal energy Power is imitated, when the heating device in water heater uses optimal efficiency Power operation, the Energy Efficiency Ratio of water heater is optimal.
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.
Step S300 heats the heating device operation that duration controls the water heater according to the target 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.
In technical solution provided in this embodiment, water heater determine user in period corresponding water consumption, and according to Water consumption determines the heating duration in advance of water heater, so that the heating device of water heater adds water according to heating duration in advance Heat so that water heater provide user during this period of time for user needed for water consumption, ensure that water heater shower effect Fruit, and water heater circulating-heating water temperature is avoided, the energy dissipation of water heater is less.
Referring to Fig. 3, Fig. 3 is the refinement flow diagram of step S200 in Fig. 2, and the step S200 includes:
Step S210 uses water parameter and the heating power according to described first, determines the water heater described the One period is corresponding to heat duration in advance；
Step S220 obtains user in second time period corresponding second and uses water parameter, and joined according to described second with water The several and described heating power determines that the water heater heats duration the second time period is corresponding in advance, wherein described First time period is adjacent with the second time period, and first time period is earlier than the second time period；
In the present embodiment, water heater needs control heating device operation in advance before first time period, so that the Period before one period is also required to control heating device and runs in advance, and so on, each of water heater on the day of Period requires to control heating device operation in advance.If but period namely second time period after first time period Second extract heating duration and be greater than at the beginning of first time period between first of section at the beginning of section and second time period When duration, water heater can be made to be run according to user in the water consumption control heating device of first time period, and make hot water Device needs to control heating device operation in advance with water parameter the second of second time period according to user, and then influences water heater and exist The temperature for the hot water that first time period provides.
Add in advance in this regard, first time period corresponding first is heated duration and the second of second time period by water heater in advance Hot duration comprehensively considers, reasonably to determine that the corresponding target of first time period heats duration in advance.
Step S230, it is corresponding according to the first time period corresponding heating duration and the second time period in advance Heating duration determines that the target of the first time period heats duration in advance in advance.
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.
When the first interval duration heats duration less than second in advance, then show that user uses water in second time period It will not influence user and use water in first time period, at this point, being mentioned using the corresponding duration of heating in advance of first time period as target Preceding heating duration.
In the present embodiment, water heater determines first time period and the second time period pair after first time period The heating duration in advance answered, to judge water heater when whether second time period influences water heater first to the heating in advance of water Between in advance heating of the section to water so that water heater reasonably determine first time period heating duration in advance, avoid hot water Device can not provide sufficient hot water after the first period of time for user.
In one embodiment, when first interval duration be greater than second time period it is corresponding in advance heat duration when, hot water Device can determine that the target of first time period heats duration namely second time period with water parameter with second with water parameter according to first Target heat duration in advance actually and be the first interval duration and heat duration in advance plus the corresponding target of first time period, at this time Without repeating to determine that the target of second time period heats duration in advance.In this regard, determining the target of first time period in water heater When heating duration in advance, it is thus necessary to determine that whether water heater determines first time period and the third before first time period simultaneously Period corresponding target heats duration, and the third period is upper adjacent with the first time period time.In this regard, water heater calculates third The the second interval duration put at the beginning of putting at the beginning of period with first time period, if the second interval duration is greater than First heats duration in advance, then can determine that water heater does not determine that the target of first time period heats duration in advance in advance, at this point, Execute step S220 and step S230.It is less than or equal to first in the second interval duration and heats duration in advance, then can determine that heat Hydrophone determines that the target of first time period heats duration in advance in advance, and water heater can heat in advance according to the target of third period Duration determines that the corresponding target of first time period heats duration in advance namely the target of third period heats duration in advance and adds The target of a length of first time period heats duration in advance when the second interval.
In the present embodiment, water heater determines point and the at the beginning of the third period before being located at first time period The second interval duration between one period, to judge that the target of first time period shifts to an earlier date duration and is according to the second interval duration No to be determined in advance, the target for avoiding water heater from recalculating first time period heats duration in advance, saves the meter of water heater Calculate resource.
Referring to Fig. 4, Fig. 4 is the refinement flow diagram of step S210 in Fig. 3, and the step S210 includes:
Step S211 determines the water discharge mode of the water heater in the corresponding maximum hot water output of the first time period Amount；
Step S212, according to the maximum hot water output and first water consumption, in each water discharge mode The corresponding first object water discharge mode of the middle determination first time period, wherein the first object water discharge mode is corresponding most Big hot water output is greater than first water consumption；
In the present embodiment, water heater be equipped with multiple water discharge modes, water discharge mode include discharge water not heating mode, discharge water plus Heat pattern 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 Degree is at 35 DEG C~45 DEG C, the when hot water of water heater output；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 the first water consumption 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 the first water consumption as first time period corresponding One target water discharge mode.Water heater is defeated further according to first object water discharge mode, the corresponding maximum hot water of first object water discharge mode Output and inflow temperature search set temperature in mapping table, which is first object set temperature.
Water heater can determine first object water discharge mode according to the first water consumption, determine the second mesh according to the second water consumption Water discharge mode is marked, the maximum hot water output of the second target water discharge mode is greater than the second water consumption, first object water discharge mode Maximum hot water output is greater than the first water consumption.
Step S213 determines that the water heater is corresponding in the first time period according to the first object water discharge mode Temperature is arranged in first object, and obtains the liner of the water heater in the corresponding liner water temperature of the first time period；
Step S214 is arranged temperature, the liner water temperature and the heating power according to the first object and determines institute State that first time period is corresponding to heat duration in advance.
After determining first object water discharge mode, that is, it can determine the first mesh set temperature of water heater, determining liner water Temperature and heating device are to the heating rate of water, and liner water temperature refers to the mean temperature of water in liner, so that it is determined that water heater Duration is heated in advance first time period is corresponding.Similarly, namely be calculated water heater second time period it is corresponding in advance Heat duration.
In technical solution provided in this embodiment, water heater determines that water discharge mode is defeated in period corresponding maximum hot water Output determines period corresponding target water discharge mode further according to maximum hot water output and water consumption, and is put according to target Aqueous mode determines target set temperature, and water heater is enabled accurately to calculate water heater according to target set temperature in the period It is corresponding to heat duration in advance.
In one embodiment, the maximum hot water output water discharge mode equal greater than the water consumption of user can be used as target and put Aqueous mode, but when difference between maximum hot water output and water consumption is larger, the hot water for showing that water heater provides is more, hot water The energy of device waste is more.In this regard, water heater first judges whether the maximum lesser water discharge mode of hot water output is that target discharges water Mode, then judge whether the biggish water discharge mode of maximum hot water output is target water discharge mode, so that water heater mentions for user The hot water of confession 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 consumption, if so, will discharge water not heating mode as 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 consumption of user, water heater is again Whether the judgement corresponding maximum hot water output of heating mode that discharges water is greater than water consumption, the corresponding maximum hot water of the heating mode that discharges water Output quantity is greater than the corresponding maximum hot water output of the not heating mode that discharges water, if corresponding maximum hot water is defeated under the heating mode that discharges water When output is greater than water consumption, 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 consumption of user, water heater will increase Molar formula target water discharge mode the most, the corresponding maximum hot water output of increase-volume mode be it is 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, spare add is arranged in water heater in the middle inside Thermal starts spare heating device when water heater enters increase-volume mode.
Water heater can determine the corresponding first object water discharge mode of first time period according to above-mentioned decision logic respectively, and The corresponding second target water discharge mode of second time period.
In technical solution provided in this embodiment, water heater first judges that the maximum lesser water discharge mode of hot water output is No is target water discharge mode, then judges whether the biggish water discharge mode of maximum hot water output is target water discharge mode, so that hot Hydrophone is that the hot water of user's supply will not be excessive in advance, and the energy dissipation of water heater is less.
In one embodiment, first time period and second time period are corresponding with target water discharge mode, and first time period with The maximum hot water output of the corresponding target water discharge mode of second time period is equal to or corresponds to slightly larger than user in the period Water consumption.But the control hierarchy of water heater heated in advance is greater than the control hierarchy of water heater energy dissipation, that is, preferentially Consider in advance heating of the water heater in each period, considers further that the energy dissipation situation of water heater.
In this regard, needing to redefine second when the duration of heating in advance of second time period is greater than the first interval duration Period corresponding second target water discharge mode.
Specifically, when the second target water discharge mode is increase-volume mode, since the corresponding maximum hot water of increase-volume mode is defeated Output is maximum in three kinds of water discharge modes, at this point, redefining the second target water discharge mode namely third target water discharge mode still For increase-volume mode；
When the second target water discharge mode is to discharge water heating mode, third target water discharge mode can be identified as increase-volume mode；
When the second target water discharge mode is to discharge water not heating mode, third target water discharge mode can be the heating mode that discharges water Or increase-volume mode.
After redefining the corresponding target water discharge mode of second time period, the heating in advance of second time period is recalculated Duration determines the further according to the duration of heating in advance for heating duration and first time period in advance of the second time period recalculated The target of one period heats duration in advance.
In technical solution provided in this embodiment, water heater is greater than the in the duration of heating in advance for determining second time period When one interval duration, the corresponding target water discharge mode of adjustment second time period is heated in advance so that water heater is segmented as far as possible, is avoided The heating and continuous duration of the heating device of water heater is too long.
In one embodiment, when water heater is used by a user by first time period, water heater has exported the heat of a part 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 etc. exported In or slightly larger than user water consumption.
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 consumption and exporting the difference between hot water amount, which is remaining use Water, water heater acquisition detects inflow temperature with the temperature sensor of liner at the bottom by setting, according to inflow temperature, residue water Target water discharge mode difference set temperature in mapping table, the set temperature determined by before temperature and water heater are For the second target set temperature of water heater, water heater controls heating device according to the second target set temperature, so that hot The energy dissipation of hydrophone is less.
In technical solution provided in this embodiment, water heater is when first time period is in and discharges water state, according to defeated The water consumption of hot water amount and user out adjust the set temperature of water heater in real time, so that the exportable hot water amount of water heater Reduce with the increase of the hot water amount exported, the energy dissipation of water heater is less.
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 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 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.
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.
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.
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.
