For the problems of the prior art, the present invention provides a kind of water heater control method, controller and water heater, thisThe bright minimum leaving water temperature by perception water heater judges the service condition to hot water for the user, and then according to user to hot waterService condition is adjusted to the design temperature of water heater automatically, so that the use that the design temperature of water heater is progressively close to the usersCustom, meets user's daily water consumption demand, allows user more to save worry.By the first to the 8th embodiment, the present invention will be carried out belowExplain in detail explanation.
The flow chart that Fig. 1 shows the water heater control method that first embodiment of the invention provides, referring to Fig. 1, thisThe water heater control method that bright first embodiment provides comprises the steps：
Step 101：Obtain the minimum leaving water temperature of preset time period heater inside.
In this step, can be by being arranged on the temperature sensor of water heater mouth to the water outlet in preset time periodTemperature is detected, and obtains the minimum leaving water temperature in this preset time period.For example, described preset time period can be oneWith water cycle, one with specified time period in the water cycle etc..Wherein, one can be one day with the water cycle.
It is understood that can also be by being arranged on the temperature sensor of water heater other positions in preset time periodLeaving water temperature detected, the present invention is not construed as limiting to this.
Step 102：Relation between outlet water temperature range is preset according to described minimum leaving water temperature and water heater, determination is repaiiedPositive temperature.
In this step, outlet water temperature range preset by described water heater can be relatively reasonable going out set in advanceThe value range of coolant-temperature gage.For example, water heater preset outlet water temperature range be 38 DEG C～45 DEG C, this outlet water temperature range forMore comfortable for family, higher or low all not so good.
When the minimum leaving water temperature (as 34 DEG C) that step 101 obtains does not preset outlet water temperature range (such as in described water heater38 DEG C～45 DEG C) interior when, illustrate that the current hot water deliverability of water heater can not meet user's request, this can lead to making of userReduced with experience, to solve this problem it is necessary to be adjusted to current design temperature, so that water heater disclosure satisfy that useThe normal water demand at family.
In this step, the relation between outlet water temperature range is preset according to described minimum leaving water temperature and water heater, reallyThe positive temperature of periodical repair, can generally comprise following several situation：
1., when described minimum leaving water temperature is less than lower limit (as 38 DEG C) that outlet water temperature range preset by water heater, heat is describedThe hot water deliverability of hydrophone can not meet user's request, now in order to meet user's request, needs to heighten water heater currentDesign temperature, therefore can determine that described correction temperature is the first positive preset value in this case；
2., when described minimum leaving water temperature is more than the upper limit (as 45 DEG C) that outlet water temperature range preset by water heater, heat is describedThe hot water deliverability of hydrophone, beyond user's request, now in order to save electric energy, should turn down the current design temperature of water heater,Therefore can determine that described correction temperature is the second negative preset value in this case；
3. when described minimum leaving water temperature be more than or equal to water heater preset outlet water temperature range lower limit and less than or waitWhen the upper limit of outlet water temperature range preset by water heater, illustrate that the hot water deliverability of now water heater disclosure satisfy that user's requestAnd do not constitute waste, thus may determine that described correction temperature is null value, do not need adjustment water heater current in this caseDesign temperature.
Step 103：It is adjusted according to the described temperature design temperature current to water heater of revising, and by the temperature after adjustmentDegree as follow-up time heater inside design temperature to realize the control to water heater；Wherein, follow-up time refers to positioned at instituteState the time after preset time period.
