Generation moment corresponding hot water temperature during hot water amount's deficiency event)/(the generation moment-upper one of current hot water amount's deficiency event
Generation moment during secondary generation hot water amount deficiency event).
S370, the generation moment corresponding mixed water according to the not enough event of the rate of heat addition, time interval and current hot water amount
Temperature computation obtains the second reference settings temperature needed under current working；Specifically, if headed by the not enough event of current hot water amount
During the event of secondary generation, the generation moment of its corresponding second reference settings temperature=current hot water amount deficiency event is corresponding mixed
The rate of heat addition * of coolant-temperature gage-the first very first time intervals, i.e. the second reference settings temperature are equal to the not enough event of current hot water amount
Occurs the difference between moment corresponding water-mixing temperature and the first temperature difference.
If the current not enough event of hot water amount is the event of N (N >=2, N is positive integer) secondary generation, its corresponding second
During generation moment of event that reference settings temperature=current hot water amount the is not enough corresponding rate of heat addition of water-mixing temperature-the first * the second

Difference between two temperature differences.
S380, by the second reference settings temperature setting be current design temperature, by heightening current design temperature, to cause
Hot water amount disclosure satisfy that the water demand of user, it is to avoid occur the not enough event of hot water amount.If for example, the not enough event of current hot water amount
For occur first event when, can be by the corresponding second reference settings temperature of the event to ensure that the current of user uses book demand
Degree is set to current design temperature.If the current not enough event of hot water amount is the event of N (N >=2, N is positive integer) secondary generation,
Can be current design temperature by the corresponding second reference settings temperature setting of the event.
As a further improvement, when occurring hot water amount's deficiency event, the above method also comprises the following steps：
By the hot water that hot water flow in the not enough event of the multiple hot water amount occurred in default second time period is maximum
Amount is not enough, and event flag is reference event；Wherein, second time period can be one day or one week etc..For example, occurring within one day
Events that 3 hot water amounts are not enough, hot water flow when event that 3 hot water amounts are not enough occurs, which respectively can be marked, is1、Q2And
Q3.By to above-mentioned Q1、Q2And Q3Maximum hot water flow can be obtained by being compared sequence, by the maximum hot water flow correspondence

(THeat 2-TIt is mixed flat)；……TBecome 10=(THeat 10-TIt is mixed flat)。
S450, the minimum water temperature changing value in multiple water temperature changing values and current design temperature, which are calculated, obtains current adjust
Save variable；Specifically, above-mentioned multiple water temperature changing values can be compared with sequence, minimum water temperature changing value is obtained, and according to
The difference of current design temperature and above-mentioned minimum water temperature changing value obtains current regulated variable.Wherein, current regulated variable=when
Preceding design temperature-minimum water temperature changing value.
S460, current design temperature is turned down to a current regulated variable, the current design temperature after being updated.Example
Such as, current design temperature is 60 DEG C, and current regulated variable is 10 DEG C, then lowers 10 on the basis of current 60 DEG C of design temperature
DEG C, the current design temperature after updating is obtained, that is, the design temperature after updating is 50 DEG C.

When, hot water amount's deficiency is may result in, thus the startup control of water heater can be adjusted according to environment temperature, to ensure the hot water
The hot water amount of device disclosure satisfy that the water demand of user.
Further, following steps are specifically included after above-mentioned steps 510：
S520, according to default one or more reference environment temperature environment temperature is divided into multiple temperature ranges, often
Individual temperature range is correspondingly arranged on one and refers to start-up temperature；In one embodiment, default reference environment temperature can be
Two, environment temperature is divided into three temperature ranges by two reference environment temperature, and each temperature range is correspondingly arranged on one
With reference to start-up temperature.For example, two reference environment temperature can be 10 DEG C and 27 DEG C, three temperature ranges can be the first temperature
Interval (- ∞, 10 DEG C), second temperature interval [10 DEG C, 27 DEG C) and the 3rd temperature range [27 DEG C ,+∞).Above three temperature
Interval is correspondingly arranged on one and refers to start-up temperature respectively.Specifically, the corresponding reference of the first temperature range (- ∞, 10 DEG C) is opened
Dynamic temperature is calculated according to current design temperature and default second temperature value and obtained；Further, the first temperature range is corresponding
