Fig. 1 is the block diagram for illustrating hot water supply apparatus according to an embodiment of the invention.
With reference to Fig. 1, hot water supply apparatus according to an embodiment of the invention may include heater 10, injection valve 20, temperature
Sensor 31, implantation temperature sensor 32 and controller 40.
Hereinafter, hot water supply apparatus according to an embodiment of the invention will be described with reference to Fig. 1.
Heater 10 can heat the water of introducing with heater heating capacity.Can be represented with watt (W) and heater 10
The relevant heater heating capacity of power consumption.Heater 10 can be uniformly heated up by presetting heater heating capacity
The water of introducing.
The heating amount of the introducing water to receiving from heater 10 can be with heater heating capacity and heater 10 plus hot water
Time (or time period) it is proportional.Thus, when the heater heating capacity of heater 10 is equably kept, to from heater
The heating amount of the 10 introducing water received can be proportional to the time period of heater 10 plus hot water.Here, the heating of heater 10 is introduced
Water time period can be according to needed for the water for introducing sprays via injection valve 20 from heater time determining, thus, can root
The heat time is adjusted according to the aperture of injection valve 20.
The operation that opens or closes of heater 10 is controlled by controller 40, and when hot water distribution signal is input into, control
Device 40 can connect heater 10, so as to heat the water of introducing with heater heating capacity.
However, when the voltage or even current unevenness of heater 10 is supplied to, it is impossible to equably keep heater to add thermal capacitance
Amount.Heater heating capacity can be by using heater voltage V, heater current I and heater resistance R (P=V*I=V^2/R
=I^2*R) at least two calculating, and can have actually about 15% to the commercial ac power power supply of the power supply of heater 10
Voltage variety.Thus, being distributed to the voltage of heater 10 can change according to the voltage variety of commercial ac power power supply,
This can cause the change of heater heating capacity.
In general, the voltage variety of commercial ac power power supply is permitted as tolerable error range, therefore, based on electricity
The difference of the heater heating capacity of pressure variable quantity can be not considered.However, it seems that Direct-type hot water supply apparatus are such to work as
Heat time it is shorter and need supply with accurate target temperature hot water when, it may be desirable to consider due to commercial ac power electricity
The error that the voltage variety in source is caused.Thus, can additionally be configured with and be supplied by commercial ac power power supply, i.e. power supply for detection
The voltage detection unit of the service voltage amplitude given.That is, the heat time of the water with regard to introducing heater 10 can be based on
Heater heating capacity is considered by the service voltage amplitude of voltage detection unit measurement and set.
Specifically, the halfwave rectifier of the executable alternating current voltage to being supplied by power supply of voltage detection unit, filtering and
Pressure drop to convert it into DC voltage, and by AD converter (ADC) by the simulation of DC voltage
Value quantifies, to be derived from service voltage value.For example, in the case of using commercial AC 220V power supply, from the confession of power supply supply
253V can be changed to from 198V due to voltage change to voltage, and voltage detection unit can divide voltage model with 10V intervals
Enclose, and service voltage is measured by any one in 200V, 210V, 220V, 230V, 240V and 250V.Thus, control
Device 40 can be based on the opening degree for supplying voltage to calculate heater heating capacity and setting injection valve 20 of correspondence measurement.
However, in order to prevent power consumption during voltage detecting, voltage detection unit can only with preheating setting time interval or
Person's ability detection voltage supply only when hot water distribution signal is input into.
Additionally, if it is known that the amplitude of any one from the voltage and current of power supply supply, then can calculate heater and add
Thermal capacity, therefore also voltage detection unit can be replaced by the current detecting unit for supplying electric current of power supply supply using detection.
The adjustable water yield sprayed from heater 10 of injection valve 20.As discussed above, sprayed from heater 10 by regulation
The emitted dose of the water for going out, can adjust the time period that the heating in heater 10 introduces the water of heater 10.Specifically, injection is worked as
When the opening degree of valve 20 is bigger, the time of the water of introducing is heated by heater 10 can be shortened, and is worked as injection valve 20 and reduced aperture
When, can lengthen for being heated the time of water of introducing by heater 10.Thus, controller 40 can pass through to adjust opening for injection valve 20
The temperature control of the water that will be sprayed from heater 10 is spent to target temperature.
Here, according to the control signal from controller 40, injection valve 20 can pass through the section for adjusting open flow passage
Accumulate size to adjust the aperture of injection valve 20 or adjust the opening time of injection valve 20.
Here, injection valve 20 may include the flow channel blocking unit of disk etc., to block water along it from heater 10
Part or all of the flow channel of distribution.Here, by adjusting the flow channel blocked by flow channel blocking unit
Cross-sectional dimension, the water yield that adjustable per unit area sprays from heater 10.
Equally, injection valve 20 can adjust per unit by being periodically repeatedly opened and closed injection valve 20 at short notice
The water yield that time sprays from heater 10, also, the periodicity opening and closing of injection valve 20 can pass through pulse width modulation
(PWM) implementing.For example, injection valve 20 receives the control of the impulse form with predetermined amount of time that is being transmitted by controller 40
Signal, when pulse is high, injection valve 20 is opened, and when pulse is low, injection valve 20 can be closed.Here, when by controller 40
In the pulse of transmission high impulse number increase when, injection valve can time per unit spray more substantial water from heater 10.
Thus, the injection water yield of time per unit, introduce heater 10 the jet velocity of water can be by using injection
Valve 20 is determining.When jet velocity accelerates, the heating in heater 10 introduces the time period shortening of the water of heater 10, because
This, can reduce the temperature of the water from the ejection of heater 10.Conversely, when jet velocity reduces, the water for introducing heater 10 is stayed in
Time period increase in heater 10, thus, the heat time increase of the water introduced by heater 10, and obtain from heater
Water temperature raise.
Here, the aperture of injection valve 20 can from fully open be continuously adjusted to completely switched off or aperture can be according to predetermined number
The purpose stage sets.For example, aperture can be divided into from fully open to completely switched off four-stage.That is, the first stage
Can be completely switched off, second stage can be 1/3 opening, the phase III can be 2/3 opening, and fourth stage can be
It is complete to open.In the case, injection valve 20 can be come with the phase sets aperture of predetermined number by using stepper motor.
Here, injection valve 20 there can be initial opening, injection temperation during initial injection is controlled to into target temperature.
That is, for water of the distribution with target temperature from water is obtained by heater 10, injection valve can be set by controller 40
20 initial opening.
The injection temperation of the measurable injection water of temperature sensor 31.As temperature sensor 31, as long as it can measure water temperature,
Any temperature sensor can be adopted.As shown in fig. 1, temperature sensor 31 may be provided between injection valve 20 and heater 10.
Thus, when injection valve 20 is completely switched off, the injection temperation measured by temperature sensor 31 can be previously stored in heater 10
Water temperature.
Hot water supply apparatus according to an embodiment of the invention may also include implantation temperature sensor 32.Implantation temperature is sensed
The inflow temperature of the measurable water for flowing into heater 10 of device 32.The inflow temperature for measuring can be used to set injection valve 20 after
Initial opening.
When hot water distribution signal is input into, the operable heater 10 of controller, and in order to start injection from original spray
Water with target temperature, controller 40 can set the initial opening of injection valve 20.
As discussed above, the injection temperation measured by temperature sensor 31 can be equal to the temperature of the water being stored in heater 10
Degree.Thus, by the initial opening that injection valve 20 is distinguished according to injection temperation in the case of original spray, can be by testing
To obtain the most appropriate aperture of injection valve 20.That is, according to the injection temperation for measuring, presetting aperture can be set as injection valve
20 initial opening, thus, can start to spray the water close to target temperature from original spray.
Here, the measurable the last water spraying time of controller 40 and next time between water spraying time using wait when
Between, and according to setting the initial opening of injection valve 20 using stand-by period and injection temperation.That is, controller 40 is it is contemplated that make
Initial opening is set with stand-by period and injection temperation.
Equally, controller 40 can receive the inflow temperature of the water being injected in heater 10, and by entering for receiving
Flow temperature, heater heating capacity and target temperature to calculate the injection flow rate that will be sprayed from heater.Thus, controller 40 can lead to
Cross using the emitted dose for calculating to set the initial opening of injection valve 20.
For example, controller 40 can pass through equationCalculate the original spray from the injection of heater 10
Amount, and the initial opening of injection valve 20 can be set according to the emitted dose for calculating.That is, controller 40 can be from implantation temperature
Sensor 32 more accurately sets the initial opening of injection valve 20 when receiving inflow temperature.Here, V is the volume of injection water, w is
The heater heating capacity of heater 10, c is the specific heat of water, and ρ is the density of water, and Δ t is the heat time, and T1 is target temperature,
And T is inflow temperature.
After original spray, controller 40 can control the aperture of injection valve according to the variable quantity of injection temperation value.
As discussed above, the water temperature for flowing into heater 10 can be with heater heating capacity and the heat time of heater 10
Proportionally increase.
In general, heater heating capacity is equably kept, therefore, controller 40 can pass through to adjust opening for injection valve 20
Spend to control the heat time of the water that heater heating is introduced.Thus, controller 40 can be according to being measured by temperature sensor 31
Injection temperation, by adjust injection valve 20 aperture by the temperature control of the water sprayed from heater 10 into target temperature.
Specifically, controller 40 can obtain the difference between injection temperation and target temperature and opening injection valve 20
It is proportional to the difference that degree controls into aperture.That is, when injection temperation is higher than target temperature, controller 40 can open injection valve
The proportional degree of difference between injection temperation and target temperature, and when injection temperation is less than target temperature, control
Injection valve can be closed the degree proportional to the difference between injection temperation and target temperature by device 40.Here, adjusting injection
During the aperture of valve 20, the aperture of injection valve 20 can be by using according between injection valve closing and injection temperation and target temperature
Proportionality expression that difference is produced or by using being set by the form for testing acquisition according to injection temperation.
However, as described above, the heater heating capacity of heater 10 can pass through the voltage change of commercial ac power power supply
Measure to change.Thus, in order to more accurately adjust temperature, it is preferred that or even being contemplated that due to the voltage of commercial ac power power supply
The variable quantity of the heater heating capacity that variable quantity is caused is setting the initial opening of injection valve 20.
So far, heater 10 may also include the voltage detection unit for detecting the service voltage supplied by power supply, and controller
40 can obtain heater heating capacity by service voltage.Specifically, heater can be actually applied to by acquisition is supplied voltage to
10 heater voltage value, and the actual heater heating capacity of heater 10 can be calculated by using heater voltage.That is,
Controller 40 can calculate actual by the way that the resistance value and heater voltage of heater 10 are replaced with for P=V*I=V^2/R
Heater heating capacity.
First, in order to set the initial opening of injection valve 20 corresponding to injection temperation, controller 40 can be using actual meter
The heater heating capacity of calculation.That is, although injection temperation is identical, if the heater heating capacity for measuring is different, initially open
Degree can be different, and the most appropriate aperture of injection valve 10 can add according to the injection temperation during original spray time and the heater for measuring
Thermal capacity to be obtained by experiment.Thus, may be set to according to the aperture of the injection temperation and heater heating capacity setting for measuring
The initial opening of injection valve 20, thus, can start just water of the injection close to target temperature from the original spray time.
Equally, when the inflow temperature of the water being injected in heater 10 is received, from the initial spray that heater 10 sprays
Water yield V can be by replacing with above-mentioned equation by the heater heating capacity of Practical CalculationIn heating
Device heating capacity w is calculating.In the case, heater heating capacity can be counted based on the voltage for being actually applied to heater 10
Calculate, based on the initial opening of the adjustable injection valve 20 of the heater heating capacity, thus can more accurately adjust temperature.
After original spray, controller 40 can be using the heater heating capacity of Practical Calculation come according to injection temperation value
Variable quantity control injection valve 20 aperture.Specifically, the scale factor proportional to heater heating capacity can be set, and
And can be between injection temperation and target temperature difference proportionally set the aperture of injection valve 40.Adjusting injection valve 20
During aperture, the aperture of injection valve 20 can be by using according between heater heating capacity and injection temperation and target temperature
Difference produce proportionality expression or by using according to heater heating capacity and injection temperation by the table for testing acquisition
Lattice are setting.
For example, the service voltage for being measured by voltage detection unit can be quantified as 200V, 210V, 220V, 230V, 240V and
250V, and can the scale factor that is previously set of with good grounds each service voltage value.Thus, the aperture of injection valve 20 can be by making
Adjusted with scale factor and injection temperation.Here, scale factor can be obtained by testing.
Here, controller 40 directly calculates heater plus thermal capacitance based on by supplying voltage to of measuring of voltage detection unit
Amount, therefore, controller can be controlled according to the voltage variety of commercial ac power power supply.Thus, it is possible to provide with using
The water of the desired target temperature of person, and or even commercial ac power power supply voltage range be different international situations still without
Process must be configured.It is i.e., or even in the voltage range of commercial ac power power supply that different international situations stills provide one
Cause property.
However, hot water supply apparatus are Direct-type hot water supply apparatus, therefore, although the initial opening of injection valve 20 according to
Injection temperation is setting, but the heating of the water for introducing can be inadequate, and can provide the water without target temperature.However,
The expection that user can provide the water with target temperature with his hot water supply apparatus carrys out injection water, therefore, for hot water supply
It is important that or even being provided with the water with target temperature within the original spray time for equipment.
Therefore, when the temperature of the water being stored in heater 10 is less than pre-warmed reference temperature, controller 40 can be
Open and operate before injection valve 20, during preheating time section heater 10.
That is, before the water that injection is stored in heater 10, the water being stored in heater 10 can be originally heated, to hold
Row is preheated with a liter high-temperature, hereafter can start injection water.In the case, the heat for requiring supply hot water is have input in user
Moisture, but can start to be provided with by response time delay for a period of time in order to preheat with after signal from the original spray time
The water of the desired target temperature of user.
Here, hot water supply apparatus can again supply hot water at once after by hot water supply to user.In this situation
Under, because the temperature of water being present in heater 10 is already close to target temperature, then need not preheat.Conversely, hot water supply
Equipment can at it by hot water supply to user after supply hot water for a long time.For example, hot water supply apparatus can be initial at its
Latter two hour supply hot water of supply hot water.In the case, the water being present in heater 10 can turn cold, so as to have with
The obvious difference of target temperature.
Thus, only when the temperature of the water of storage is less than preheats reference temperature, such as 60 degrees Celsius or less, controller
40 can check the water temperature being stored in heater 10 by using temperature sensor 31.
Equally, preheating time can be set to and work as the temperature of the water being stored in heater 10, sprays by controller 40
When temperature is relatively low, extend preheating time.Because the difference between injection temperation and target temperature increases, can be by preheating time
It is set as lengthening, the water being stored in abundant heating in heater 10.Conversely, when injection temperation is higher, because temperature is close to
In target temperature, the water being stored in heater 10 heating can be sufficiently achieved the shorter time period of target temperature.
Additionally, the measurable the last water spraying time of controller 40 and next time between water spraying time using wait when
Between, and according to the injection temperation for measuring setting the aperture of preheating time and injection valve 20.
When stop hot water distribute signal input when, hot water supply apparatus can completely switched off injection valve 20, to cut off hot water
Supply, and in the case, the water being stored in heater 10 may be at being heated to the state of target temperature.However,
In the case, when no longer operating after hot water supply apparatus, the temperature of the water being stored in heater 10 can be over time
Reduce.Thus, the aperture of injection valve 20 is contemplated that using the temperature between stand-by period and target temperature and injection temperation
Difference is setting.
Additionally, in order to quickly distribute the water with target temperature, controller 40 can according to the variable quantity of injection temperation value come
Adjust the aperture of injection valve 20.By with reference to Figure 4 and 5 describing the concrete operations relevant with the operation of controller 40.
Fig. 4 (a) is the curve map for illustrating the injection water temperature in the case of first time sprays water.That is, Fig. 4 (a) is illustrated from nearest
The curve map that hot water is sprayed after certain hour is have passed through after water spray.With reference to Fig. 4 (a), it can be seen that it is mesh that injection temperation is converged
Temperature is marked, and this can be obtained by the aperture of injection valve controlled as described above.
However, in the case, as shown in Fig. 4 (a), injection temperation is being converged injection temperation the mistake for target temperature
Fluctuated up and down based on target temperature in journey, and according to the fluctuation of injection temperation, undesirably can be supplied to user very hot
Water or cold water.Equally, the time that injection temperation is stabilized to needed for target temperature is made to lengthen.Thus, it is desirable to control injection valve
20 so that the fluctuation of injection temperation curve to be minimized.
Fig. 4 (b) is the curve map for illustrating the injection water temperature in the case of continuous water spray.Due to continuous dispensing hot water, injection
Temperature is not substantially increased in the starting stage as Fig. 4 (b), but occurs fluctuation in injection temperation curve.Thus, it is desirable to control
Injection valve processed 20 is so that fluctuation to be minimized.
Therefore, controller 40 can calculate the variable quantity of injection temperation value, and according to the variable quantity for calculating adjusting injection
The aperture of valve 20, is thus minimized fluctuation.
First, controller 40 can calculate the difference between injection temperation and target temperature, and according to difference determining
Hot water distribution is to spray water first or continuous water spray.
For example, when the difference between injection temperation and target temperature is equal to or more than pre-set value, controller 40 can be true
Determine hot water to extract is to spray water first, and when the difference between injection temperation and target temperature is less than pre-set value, controller 40
Can determine that hot water is extracted is continuous water spray.
Here, the difference that starting stage when can distribute hot water is started is obtained between injection temperation and target temperature, and
And in the case, can substantially distinguish water spray and continuous water spray first.
That is, in the case of spraying water first, the temperature of the water being stored in heater 10 approaches in room temperature that (about 26 is Celsius
Degree), but in the case of continuous water spray, due to heated water, then the temperature of the water being stored in heater 10 can almost etc.
In target temperature (85 degrees Celsius).
Thus, based on the difference between injection temperation and target temperature, water spray and continuous water spray first can be distinguished, and is sprayed
Penetrating valve 20 can differently control according to water spray first and continuous water spray.
When it is to spray water first that hot water is extracted, controller 40 can calculate the variable quantity of injection temperation, and according to injection temperation
Variable quantity adjusting the aperture of injection valve 20.
Can be measured by being spaced with each preheating setting time between the injection temperation value that injection temperation and calculating are measured
Difference obtaining the variable quantity of injection temperation.Here, when the variable quantity of the injection temperation for calculating is equal to or more than the first reference
During variable quantity, it is believed that injection temperation is quickly raised, and in this case, it is possible to increase the fluctuation number of times of injection temperation curve and
Fluctuating range.
Thus, when variable quantity is defined as quickly increasing, the aperture of injection valve 20 is securable to when the variable quantity is calculated
Aperture, and fixed aperture can be kept the first predetermined amount of time.That is, in order to reduce the variable quantity of injection temperation, can make
First preheating setting time section is stopped according to control of the injection temperation to the aperture of injection valve 20, thus, injection is reduced as shown in Figure 5
The variable quantity of temperature.
With reference to Fig. 4 (a), or even in the case where spraying water first, injection temperation can be incrementally increased as time go on, and
Difference between injection temperation and target temperature is smaller than pre-set value.Thus, in the case, controller 40 can with it is continuous
Water spray identical mode is controlling the aperture of injection valve 20.Hereinafter, will be described in the case of continuous water spray to controller 40
Operation.
When as mentioned above hot water extraction being defined as into continuous water spray, the variable quantity of injection temperation, and change can be calculated
Whether amount is equal to or more than the second reference variation amount.Second reference variation amount can be less than the value of the first reference variation amount.When
When variable quantity is equal to or more than the second reference variation amount, it is believed that injection temperation is slowly raised.
When injection temperation is slowly raised, it is contemplated that the fluctuating range and fluctuation number of times increase to injection temperation, thus, injection
The aperture of valve 20 can be fixed as calculating the aperture during variable quantity.Here, when regular time section can be more presetting than first
Between short the second preheating setting time section of section, and the variable quantity of injection temperation can be by stopping reducing the control of injection valve 20.
Thus, the aperture of injection valve 20 is adjusted by the variable quantity according to injection temperation, injection temperation can fast convergence
For target temperature, and the control time of injection valve 20 is shortened by, the energy produced by the control due to injection valve 20 can be saved
Amount is consumed.
Although not shown, water purifier can include hot water supply apparatus.Water purifier may include to filter by main water supply system
The polishing filter of the running water for being supplied, and the water for being cleaned filter cleaning can be introduced heater 10.Hereafter, purify
Water heating and subsequently can be sprayed to be supplied to user by injection valve 20 in the heater 10.Here, controller 40 can
The aperture of control injection valve 20, by the temperature adjustment of distribution water to target temperature.Similarly, controller 40 can be by using temperature
Spend sensor 31 and implantation temperature sensor 32 to adjust the aperture of injection valve 20, and by controlling heater 10 and injection valve
20 come to introduce heater 10 water preheat.
Fig. 2 is the flow chart for illustrating hot water supply method according to an embodiment of the invention, and Fig. 3 is illustrated according to this
The flow chart of the initial injection operation of the hot water supply method of a bright embodiment.
With reference to Fig. 2 and 3, hot water supply apparatus according to an embodiment of the invention may include initial injection operation (S10) and
Injection control operates (S20).Initial injection operation (S10) may include that initial opening sets process (S11), preheating process
And initial opening procedure (S13) (S12).
Hereinafter, hot water supply method according to an embodiment of the invention will be described with reference to Fig. 2 and 3.
In initial injection operation (S10), when hot water supply signal is input into, set for adjusting from heater spray
The initial opening of the injection valve of injection flow rate, and injection valve can open presetting aperture.Initial injection operation (S10) is heating
The operation that device starts to spray water according to the hot water supply signal of input.In this operation, the initial opening of injection valve can be set, with from
Original spray starts just water of the distribution with target temperature.
Specifically, initial injection operation (S10) may include initial opening setting operation (S11) and initial opening operation
(S13)。
In initial opening setting operation (S11), presetting aperture can be set as by injection valve according to injection temperation
Initial opening.
Injection temperation is measured by using the temperature sensor between heater and injection valve is positioned at.Opening injection
Before valve, injection temperation can be previously stored the temperature of the water in heater.Thus, the temperature of the water being stored in heater can
By using opening the injection temperation before injection valve measuring, and the initial opening of injection valve can according to the water temperature for measuring come
Setting.
Specifically, the time that the temperature of the water being stored in heater can begin to pass through according to spraying water from the last time
Change, accordingly, it would be desirable to change initial opening according to the water temperature being stored in heater.
For example, when from last time injection water through one minute, the temperature of the water of storage is approached in target temperature,
Therefore, without the hot water long period is added, thus, initial opening can be set to allow to spray relatively great amount of water.
Meanwhile, when two hours are begun to pass through from last time injection water, the temperature meeting of the water of storage and target temperature
It is dramatically different, accordingly, it would be desirable to pass through one section of long period of heater plus hot water.In the case, initial opening can be set to permit
Perhaps the relatively small water yield is sprayed.
Here, with regard to depending on the initial opening of injection temperation, passing through to change injection valve according to the injection temperation for measuring
Initial opening to obtain optimal initial opening by experiment, thus, injection can be preset according to corresponding injection temperation
The initial opening of valve.
Additionally, as discussed above, can according to the elapsed time from nearest water spraying time, i.e. the last injecting time
The temperature for changing the water being stored in heater using the stand-by period between water spraying time next time.Thus, initial
In aperture setting operation (S11), the last water spraying time of measurement and next time the use stand-by period between water spraying time, and
And can set the initial opening of injection valve by using stand-by period and injecting time.
In initial opening setting operation (S11), in addition to injection temperation, the water of introducing heater can be further received
Inflow temperature, based on the inflow temperature initial opening of injection valve can be set.
Specifically, the original spray amount of the heater needed for water of the injection with target temperature can be by using equationTo calculate, and the initial of injection valve can be set according to the initial injection quantity of the heater for calculating
Aperture.That is, the initial opening of injection valve can be more accurately set when inflow temperature is received.Here, V is the body of injection water
Product, w is the heater heating capacity of heater 10, and c is the specific heat of water, and ρ is the density of water, and Δ t is the heat time, and T1 is target
Temperature, and T2 is inflow temperature.
However, in the case, it is uniformly to assume to set initial temperature based on the heater heating capacity of heater,
But in fact, the heater heating capacity of heater can become according to the voltage of the commercial ac power power supply to heater fed power supply
Change amount is changing.Thus, in order to set the more accurate initial opening of injection valve, the change for considering heater heating capacity is needed
Change.
So far, initial injection operation (S10) may also include heater heating capacity and calculate operation (not shown), and add
Hot device heating capacity is calculated in operation, the measurable service voltage supplied by power supply, and can be by using supplying voltage to meter
Calculate heater heating capacity.
Specifically, calculate in operation in heater heating capacity, the exchange electrical supply voltage supplied by power supply can be converted
Into DC voltage, and the DC voltage for converting can quantify to detect service voltage.That is, the alternating current electricity for being supplied by power supply
By halfwave rectifier, filtering and pressure drop to change into DC voltage, hereafter, DC voltage quantifies thus to survey pressure by ADC
Amount service voltage.Thus, during the AC commercial piezoelectric voltage of the 220V for changing to 253V from 198V when supply, power is with 10V intervals
To divide, to measure as any one in 200V, 210V, 220V, 230V, 240V and 250V.Due to the resistance of heater
Value is uniform, when service voltage is measured, can obtain the heater voltage value for putting on heater, and can be by using P
=V*I=V^2/R is readily calculating heater heating capacity.
Hereafter, in initial opening setting operation (S11), heater heating capacity calculate operating process in by using
The heater heating capacity for calculating is setting the aperture of injection valve.Specifically, in initial opening setting operation (S11),
Although injection temperation is uniform, if the heater heating capacity for calculating is different, but change the aperture of injection valve, and
Injection valve can experimentally be obtained most according to injection temperation during first water spraying time and the heater for measuring heating capacity
Appropriate aperture.Thus, predetermined aperture can be set as by injection valve according to the injection temperation and heater heating capacity that measure
Initial opening.
Equally, when the inflow temperature of the water being injected in heater is received, from the original spray that heater 10 sprays
Amount V can be by being replaced by above-mentioned equation V=by the heater heating capacity of Practical CalculationIn heater add
Thermal capacity w is calculating.In the case, heater heating capacity can be calculated based on the voltage for being actually applied to heater 10,
Based on the initial opening of the adjustable injection valve 20 of the heater heating capacity, temperature thus can be more accurately adjusted.
Additionally, calculate in operation in heater heating capacity, with each preheating setting time interval or when input hot water point
During with signal, the measurable voltage supplied by power supply, i.e. service voltage.This reduce the power needed for for measuring service voltage
Consume.
Although having set the injection valve for water of the distribution with target temperature in initial opening setting operation (S11)
Initial opening, but if the temperature of the water being stored in heater is too low, then the water for distributing can not be sufficiently heated, thus, meeting
The not water with target temperature is provided.
Thus, initial injection operation (S10) also includes preheating operation (S12).When the injection temperation for measuring is less than pre-add
During hot reference temperature, heater is operable to during preheating time section heat the water being stored in heater.Work as storage
Water in heater is less than when preheating reference temperature, before ejecting pre-add hot water.Thus, when preheating operation
(S12) when spraying water after, can start to spray the water with target temperature from water spraying time first.
Specifically, when the injection temperation for measuring is less than 60 degrees Celsius, can carry out preheating operation (S12), and
In the case that the injection temperation that measures is relatively low, preheating time is set as to lengthen, with the water of abundant pre-add hot heater.
Here, initial opening setting operation (S11) and preheating operation (S12) and while carry out, or can first carry out pre-
Heating operation (S12), and in initial opening setting operation (S11), it is contemplated that the pre-add during operation (S12) is preheated
The temperature of the water of heat is setting the initial opening of injection valve.
In initial opening operation (S13), injection valve can be opened according to the presetting aperture of injection valve.By initially opening
Degree setting operation (S11) and operation (S12) is preheated providing the water with target temperature, hereafter, can carry out injection control behaviour
Make (S20) and provide the water with target temperature with continuous even in injection water.
In injection control operation (S20), can be adjusted to by controlling the aperture of injection valve from the water of heater spray
With target temperature.
Here, the aperture of injection valve can be adjusted according to the variable quantity of injection temperation value.Specifically, when injection temperation is high
When target temperature, injection valve can open the proportional degree of difference between injection temperation and target temperature, and when spray
When penetrating temperature less than target temperature, injection valve can be closed the journey proportional to the difference between injection temperation and target temperature
Degree.
When the heater heating capacity of heater is uniform, can add with heater from the temperature of the water of heater spray
The time segment length of hot water proportionally increases.When injection valve is opened to a greater degree, increase the injection flow rate of time per unit,
Thus, heater adds the time period of hot water to shorten.Meanwhile, when injection valve is closed, the injection flow rate of time per unit is reduced, by
This, heater adds the time period of hot water to lengthen.
Thus, in injection control operation (S20), can be adjusted from heater spray by adjusting the aperture of injection valve
The temperature of water, and can be by from the temperature adjustment of the water of heater spray into reaching target temperature.
Equally, in injection control operation (S20), the inflow temperature of the water being injected in heater can be received, and is led to
Cross using inflow temperature, the heater heating capacity of heater and target temperature to adjust the aperture of injection valve.
Specifically, in order to be sprayed with target by using inflow temperature, heater heating capacity and target temperature
The water of temperature, can calculate required emitted dose, and the aperture of injection valve can be adjusted based on the emitted dose for calculating.
For example, the injection flow rate of the heater needed for water of the injection with target temperature can be by using equation VTo calculate, and the aperture of injection valve can be set according to the emitted dose for calculating.That is, can receive
The aperture of injection valve is more accurately set during inflow temperature.Here, V is the volume of injection water, w is that the heater of heater 10 adds
Thermal capacity, c is the specific heat of water, and ρ is the density of water, and Δ t is the heat time, and T1 is target temperature, and T2 is inflow temperature.
However, in the case, as discussed above, heater heating capacity alterable, therefore, in order to more accurately control
Temperature processed, can add thermal capacitance by using the actual heater of the heater measured in calculating operating process in heater heating capacity
Measure to adjust the aperture of injection valve.
Specifically, the scale factor proportional to heater heating capacity can be set, and can be with injection temperation and mesh
Difference between mark temperature proportionally sets the aperture of injection valve.So far, can use according to injection temperation and target temperature it
Between the proportionality expression that produces of difference and heater heating capacity, or can use according to heater heating capacity and injection
Temperature is by the form for testing generation.
Equally, when the temperature of the water being input in injection heating device, the emitted dose of heater can be by by Practical Calculation
Heater heating capacity is replaced by above-mentioned equationIn heater heating capacity (w) calculating.
In injection control operation (S20), in order to rapidly distribute the water with target temperature, can be by using injection temperature
The variable quantity of angle value is adjusting the aperture of injection valve.
Fig. 4 (a) is the curve map for illustrating the injection water temperature in the case of spraying water first.That is, Fig. 4 (a) is illustrated from spray recently
Water plays the curve map for spraying hot water after a predetermined time.With reference to Fig. 4 (a), it can be seen that it is target temperature that injection temperation is converged,
And this can be obtained by the aperture of injection valve controlled as described above.
However, in the case, as shown in Fig. 4 (a), injection temperation is being converged injection temperation the mistake for target temperature
Fluctuated up and down based on target temperature in journey, and according to the fluctuation of injection temperation, undesirably can be supplied to user very hot
Water or cold water.Equally, the time that injection temperation is stabilized to needed for target temperature is made to lengthen.Thus, it is desirable to control injection valve
So that the fluctuation of injection temperation curve to be minimized.
Fig. 4 (b) is the curve map for illustrating the injection water temperature in the case of continuous water spray.Due to continuous dispensing hot water, injection
Temperature is not substantially increased in the starting stage as Fig. 4 (b), but occurs fluctuation in injection temperation curve.Thus, it is desirable to control
Injection valve processed is so that fluctuation to be minimized.
Thus, injection control operation (S20) in, according to calculate variable quantity come adjust injection temperation value variable quantity and
The aperture of injection valve, so that fluctuation is minimized.
First, in injection control operation (S20), the difference between calculating injection temperation and target temperature, and according to
Difference come determine hot water distribution be first water spray or continuous water spray.
When the difference between injection temperation and target temperature is equal to or more than pre-set value, headed by hot water distribution can determine that
Secondary water spray, and when the difference between injection temperation and target temperature is less than pre-set value, hot water distribution can be identified as continuous spray
Water.
Here, the difference that the starting stage that can distribute when starting in hot water is obtained between injection temperation and target temperature, and
And in the case, can substantially distinguish water spray and continuous water spray first.
That is, in the case of spraying water first, the temperature of the water being stored in heater approaches in room temperature that (about 26 is Celsius
Degree), but in the case of continuous water spray, due to adding hot water, the then temperature of the water being stored in heater 10 to be no better than
Target temperature (85 degrees Celsius).
Thus, based on the difference between injection temperation and target temperature, water spray and continuous water spray first can be distinguished, and can
Injection valve 20 is differently controlled according to water spray first and continuous water spray.
When it is to spray water first that hot water is extracted, controller 40 can calculate the variable quantity of injection temperation, and according to injection temperation
Variable quantity adjusting the aperture of injection valve 20.
Can be measured by being spaced with each preheating setting time injection temperation value that injection temperation value and calculating measures it
Between difference obtaining the variable quantity of injection temperation.Here, when the calculating variable quantity of injection temperation is equal to or more than the first reference
During variable quantity, it is believed that injection temperation is quickly raised, and in this case, it is possible to increase the fluctuation number of times of injection temperation curve and
Fluctuating range.
Thus, when variable quantity is defined as quickly increasing, the aperture of injection valve 20 can be fixed as when the variable quantity is calculated
Aperture, and fixed aperture can be kept the first predetermined amount of time.That is, in order to reduce the variable quantity of injection temperation, can be by
First preheating setting time section is stopped according to control of the injection temperation to the aperture of injection valve 20, thus, spray is reduced as shown in Figure 5
Penetrate the variable quantity of temperature.
With reference to Fig. 4 (a), or even in the case where spraying water first, injection temperation can be stepped up as time go on, and spray
The difference penetrated between temperature and target temperature is smaller than pre-set value.Thus, in the case, controller 40 can with continuous spray
Water identical mode is controlling the aperture of injection valve 20.Hereinafter, the control method in the case of continuous water spray will be described in.
When hot water as described above is extracted is defined as continuous water spray, the variable quantity of injection temperation, and variable quantity can be calculated
Whether the second reference variation amount is equal to or more than.Second reference variation amount can be less than the value of the first reference variation amount.Work as change
When change amount is equal to or more than the second reference variation amount, it is believed that injection temperation is slowly raised.
When injection temperation is slowly raised, it is contemplated that the fluctuating range and fluctuation number of times increase to injection temperation, thus, injection
The aperture of valve 20 is securable to calculate the aperture during variable quantity.Here, when regular time section can be more presetting than first
Between short the second preheating setting time section of section, and the variable quantity of injection temperation can reduce by stopping the control of injection valve 20.
Thus, the aperture of injection valve 20 is adjusted by the variable quantity according to injection temperation, injection temperation can fast convergence
For target temperature, and the control time of injection valve 20 is shortened by, the energy produced by the control due to injection valve 20 can be saved
Amount is consumed.
