Below according to a kind of control method for electric heater that the structure of electric heater above proposes, including following step
Suddenly：
S10, the duration control instruction for receiving user, and target water duration is obtained according to duration control instruction；
In the present embodiment, user is sent to electric heater there are many modes of duration control instruction, for example, user can make
It is sent by wireless network with mobile terminal (for example, remote controler, mobile phone, tablet electric energy, Intelligent bracelet, smartwatch etc.),
Can also duration control instruction directly be sent by physical button.Electric heater after getting duration control instruction, according to
The mapping table of preset duration control instruction and target water duration obtains, when target water corresponding with duration control instruction
It is long.I.e. electric heater knows user will need use use water how long, i.e. electric hot water according to the duration control instruction of user
Device obtains the time span for needing to supply water for user.
S20, required hot water is calculated according to target water duration, preset mixed water water temperature and/or preset mixed water flow velocity
Target hot water water and/or target hot water water temperature；
In the present embodiment, after obtaining target water duration, according to target water duration, preset mixed water water temperature and/or
Preset mixed water flow velocity calculates the target hot water water and/or target hot water water temperature of required hot water.Wherein, target hot water water temperature is high
In preset mixed water water temperature, target hot water water is less than or equal to liner capacity.Certainly, in some embodiments, target heat
Water water (required hot water water) may also be more than liner capacity, at this time, it may be necessary to being entirely scheduled with the water period.Wherein,
Target hot water water temperature and target hot water water with target water duration, preset mixed water water temperature, preset mixed flow short-term training just
Than, i.e., when target, with water duration, longer, preset mixed water water temperature is higher, when preset mixed water flow velocity is faster, target hot water water temperature
Higher, target hot water water also will be bigger.I.e. user needs longer with the time of water, higher with the temperature of water, with the flow velocity of water
It is faster, the water temperature of heating will be required to improve, the water of heating increases.Wherein, mixing water water temperature and mixed water flow velocity can pre-set,
User can also be adjusted according to actual conditions.Due to consideration that user in real time use regimen condition, target with water duration not
In the case of change, target hot water water and target hot water water temperature all in real time as mixed water water temperature and mixed water flow velocity are changed,
So that the heating state of electric heater is always on the basis of target water duration, regimen is used with what minimum energy consumption met user
Condition.
Meet the relationship of inverse correlation between target hot water water temperature and target hot water water, that is, when target hot water water temperature increases
When, target hot water water can be reduced accordingly；When target hot water water temperature reduces, target hot water water needs corresponding increase
Add.
Certainly, in some embodiments, since the capacity of liner is certain, target hot water water is the capacity of liner, at this time
Common target hot water water temperature can be calculated.
S30, preset heating component is selected according to target hot water water and/or target hot water water temperature.
In the present embodiment, corresponding different target hot water water and target hot water water temperature are provided with different heating groups
Part.Centainly due to heating duration (target water duration), target hot water water temperature and target hot water water with the work(of heating component
Rate is positively correlated.That is, target hot water water temperature is higher, target hot water water is more, then the heating work(of corresponding heating component
Rate is higher；Target hot water water temperature is lower, and target hot water water is fewer, then the heating power of corresponding heating component is lower.
In the present embodiment, the duration control instruction of user is received by electric heater, and obtain according to duration control instruction
Target water duration；Required hot water is calculated further according to target water duration, preset mixed water water temperature and/or preset mixed water flow velocity
Target hot water water and/or target hot water water temperature；Then, it is selected according to target hot water water and/or target hot water water temperature pre-
If heating component；In above-mentioned technical proposal, by user's needs with based on water time span, regimen is used in conjunction with user
Condition calculates and currently needs the water of hot water and the water temperature of hot water, the water temperature selection of water and hot water further according to required hot water
Suitable heating component while to meet user's water demand, reduces the energy consumption of electric heater.

Wherein, it is worth noting that the second preset duration occurred in the first preset duration and following example is to
Nine preset durations, respectively less than or equal to target water duration.In the case of the useful water parameter constant of institute, water heater is from the beginning of
It is heated to stop heating to heat always at this point, preset duration is equal with water duration with target using same group of heating component
Stop using water to user, at this point, hot water is also just finished.When user's water Parameters variation, the heating component of work is the
Switch in one heating component to the 9th heating component, at this point, the sum of first preset duration to the 9th preset duration is used equal to target
Water duration.In this way, ensure user with water simultaneously, the energy consumption of water heater is minimized.
