Example is applied based on having the water heater of mixed water function to be realized, specifically, water heater has constant-temperature effluent valve, to guarantee water temperature out
Degree is the default water temperature of user.
As shown in Figure 1, the acquisition methods of the water heater residue water duration of the embodiment of the present invention, comprising the following steps:
S101: the first leaving water temperature T1 at water heater current time is obtained.
Wherein, temperature-detecting device can be set in the water outlet of water heater, for detecting the leaving water temperature of water heater.
S102: the first leaving water temperature T1 and preset first temperature difference (T1-T) between coolant-temperature gage T are obtained.
Wherein, it is preset with coolant-temperature gage T can be user preset demand water temperature.
S103: if first temperature difference (T1-T) is less than preset threshold value Δ T, the first water of current time water heater is obtained
Warm fall off rate V1.
S104: according to first temperature difference (T1-T) and the first water temperature drop rate V1, the residue water duration of water heater is obtained
t。
Specifically, when user uses water heater heat can be obtained by detecting the leaving water temperature of water heater mouth
The first leaving water temperature T1 at hydrophone current time calculates the first leaving water temperature T1 according to the first leaving water temperature T1 and preset uses water
First temperature difference (T1-T) between temperature T then judges the size relation of first temperature difference (T1-T) Yu preset threshold value Δ T,
In, preset threshold value Δ T should be the temperature that can satisfy the water demand of user's certain time, therefore, as the first temperature difference (T1-
When T) being greater than or equal to preset threshold value Δ T, then it represents that water temperature is enough, and user can be used normally, as first temperature difference (T1-T)
When less than preset threshold value Δ T, then it represents that water temperature is not high enough, and hot water amount may be insufficient for the water demand of user, at this point,
The the first water temperature drop rate V1 for needing to further calculate water heater, i.e., disappear speed according to the actual hot water of user to determine residue
With water duration t.
The present embodiment can determine remaining water duration with regimen condition according to user is actual as a result, therefore obtain
Residue is more in line with the actual conditions that user uses with water duration, thus allow users to know current residue water duration,
The bathing time is adjusted according to residue water duration convenient for user, without the available feelings of hot water caused by avoiding because of residue water duration deficiency
Condition influences the experience of user.
According to one embodiment of present invention, according to first temperature difference (T1-T) and the first water temperature drop rate V1, heat is obtained

Compare, determines that the first water temperature drop rate V1 is greater than preset water temperature drop rate V0.
That is, obtaining the first of current time water heater when first temperature difference (T1-T) is less than preset threshold value Δ T
Water temperature drop rate V1, then judges whether the first water temperature drop rate V1 is less than preset water temperature drop rate V0, if the
One water temperature drop rate V1 is less than or equal to preset water temperature drop rate V0, then it represents that water temperature drop is slower, and water heater can be
Continue to heat during hot water decline, to meet the water demand of user, be preset if the first water temperature drop rate V1 is greater than
Water temperature drop rate V0, then it represents that water temperature drop is very fast, hot water consumption rate be greater than preset rate, even if water heater after
The water demand that continuous heating is also unable to satisfy user is worked as at this time, it may be necessary to be calculated with the water time residue so that user knows
The duration that preceding hot water amount is able to use.
It should be understood that preset threshold value Δ T can be obtained by preset water temperature drop rate V0.Due to default
Threshold value Δ T be meet user's certain time use coolant-temperature gage, i.e., under conditions of preset water temperature drop rate V0, Yong Huyong
Water preset time t ', then preset threshold value Δ T=V0*t '.Based on this, when the first water temperature drop rate V1 is less than preset water temperature
When fall off rate V0 and first temperature difference (T1-T) are less than preset threshold value Δ T, according to law of conservation, residual time length t is centainly less than
Preset time t ', the use time t ' that user preset is unsatisfactory for using the time of hot water surplus.
According to one embodiment of present invention, according to first temperature difference (T1-T) and the first water temperature drop rate V1, heat is obtained
The residue of hydrophone water duration, comprising: obtain the ratio between first temperature difference (T1-T) and the first water temperature drop rate V1, will compare
Value uses water duration t as remaining.

When with water, corresponding preset time is user's water preset time t ', in water utilizing process, corresponding preset time applies user
With water preset time t ' subtract the use water duration having already been through.For example, user's water preset time t ' be 30 minutes when, when with
When family is started with water, corresponding preset time be should be 30 minutes at this time, when user takes a shower 10 minutes, when corresponding at this time default
Between should be 20 minutes, when user take a shower 15 minutes when, corresponding preset time should be 15 minutes at this time.
That is, after calculating acquisition residue water duration, when needing to remind to user, and residue being used water
It is long to be sent to user, and when residue is less than preset time with the water time, hydropenic prompting message is issued, is allowed a user to
Enough residues obtained that calculates further are selected with water duration, such as wait the hot water of water heater heating sufficient amount, are for another example led to
It crosses and output water temperature such as is turned down at the modes reduces water temperature drop rate etc., family can be used in other words and used according to residue water time adjustment
Water mode, to guarantee user to the use demand of hot water, user experience is bad caused by hot water amount's deficiency when avoiding because using hot water
The problems such as.
Further, after the residue for obtaining water heater is with water duration t, further includes: obtain what water heater was persistently discharged
First duration t1, if after the first duration t1 reaches the first preset duration t ', control, which returns to execute, obtains water heater current time
The first leaving water temperature T1 and subsequent step.
That is, when water heater is persistently discharged, the first duration t1 that water heater is persistently discharged is obtained, if when first
Long t1 reaches the first preset duration t ', then controls to return and execute the first leaving water temperature T1 for obtaining water heater current time and subsequent
Step carries out primary remaining water duration every the first preset duration t ' and judges to realize when user persistently uses water, Jin Erfang
The problem of only user causes new hot water water shortage with coolant-temperature gage due to adjustment when continuing with water, or in residue water duration
It is reminded when insufficient, promotes the experience of user.
It should be understood that when re-starting the remaining calculating with the water time after the first preset duration t ', water temperature drop
Rate is then calculated by the second current output water temperature T2, the first output water temperature T1 and the first preset duration t ', specifically,
V2=(T2-T1)/t '.In other words, continue in water utilizing process in user, when persistently calculating current water temperature fall off rate, using current
Output water temperature, previous period output water temperature and preset interval time are calculated.
Relatively, if detecting that water heater is not discharged persistently, the time duration not being discharged persistently is obtained；If when accumulative
It is long to reach preset second duration, then reclocking is carried out to the first duration when water heater is discharged again.Wherein, it should be understood that
, since it is currently detected be not discharged timing, continuous timing obtains time duration.After detecting water outlet, add up herein
Duration can reset.
That is, the time duration of user not being discharged persistently is detected if user is not continual to use water, when
When persistently water outlet duration does not reach preset second duration, then being discharged again in water heater is counted again to the first duration
When, to avoid that prompting is also repeated in the unused water of user, influence user experience, such as user is of short duration in use
The case where closing water heater, specifically, it may include when user takes bath article etc..
