As shown in Figure 1, the control method of the electric heater of the embodiment of the present invention, comprises the following steps:
S101, the water Information generation user of recording user in predetermined period water habits table, wherein, water habits table record has water consumption, water duration and the water set temperature in a plurality of default time zones of user in predetermined period.
In one embodiment of the invention, electric heater has intelligent memory functional, can carry out the water information of recording user in predetermined period by opening intelligent memory functional, for example the water habits of recording user in one week is as shown in table 1, for user's water habits table of some day in a week of record, is assumed to be the water situation of user on Monday, for example, in 19:00～22:00 time zone, user's water 10min, 60 ℃ of water temperatures, water consumption is 25L.
Table 1
S102, detects the water instruction that whether receives user.
In one embodiment of the invention, having under electricity condition of electric heater start/shutdown, if user has opened intelligent memory functional, the detection module of electric heater can detect the discharge of electric heater in real time, can detect user in the water situation in default time zone by detecting the flow status of discharge.Particularly, detection module detects discharge and whether is more than or equal to preset flow threshold value, if so, calculates the water time in time zone corresponding to current time.For example preset flow threshold value is made as 2L/min, detect discharge and whether be more than or equal to 2L/min, if discharge detected, be more than or equal to 2L/min, or discharge rises to 2L/min below by 1.5L/min or more than 2L/min, be judged as the water instruction that may receive user, and calculate the water time in the time zone of current correspondence, the water instruction that may receive user for example in the 19:00～22:00 of time zone, detected, when receiving water instruction, judgement calculates the time of user's water in district at this moment, say, if the water instruction that may receive user detected in current time zone 19:00～22:00, the accumulation water time counter in this time zone starts timing, end of extent arrives 22:00 constantly heretofore, the water time counter in this time zone stops timing, open the water time counter in next time zone, for example finish during 19:00～22:00 time zone meter, the water time counter of opening 22:00～00:00 time zone carries out timing, until user's water no longer.In addition, when detecting, discharge is less than 1.5L/min or discharge drops to 1.5L/min above by 2L/min or 2L/min, and judgement does not receive user's water instruction.
In one embodiment of the invention, when judging the water instruction that may receive user, and calculate water in time zone corresponding to current time after the time, whether the water time that also needs judgement to calculate is greater than the first Preset Time is less than the second Preset Time, wherein, the first Preset Time is less than the second Preset Time.If so, judgement receives user's water instruction, and water instruction is the first water instruction.Particularly, for example establishing the first Preset Time is 3min, and the second Preset Time is 10min, and calculating the water time obtaining is T.Judge whether T is greater than 3min and is less than 10min, if T is greater than 3min and is less than 10min, the user's who receives water instruction is the first water instruction, the first water instruction can be the situation of a small amount of water of user.More specifically, aspect data arrange, can user by aqueous condition memory cell, be set to 1 situation that represents to receive the first water instruction of user.
In another embodiment of the present invention, if the water time is more than or equal to the second Preset Time, judgement receives user's water instruction, and water instruction is the second water instruction; If the water time is less than or equal to the first Preset Time, judgement does not receive user's water instruction.Particularly, for example establishing the first Preset Time is 3min, and the second Preset Time is 10min, and calculating the water time obtaining is T.If T is more than or equal to 10min, judgement receives user's water instruction, and water instruction is the second water instruction, and the second water instruction can be the situation of a large amount of waters of user.If T is less than or equal to 3min, judgement does not receive user's water instruction.More specifically, aspect data arrange, can user by aqueous condition memory cell, be set to 2 situations that represent to receive the second water instruction of user, user is set to 0 situation that represents not receive user's water instruction by aqueous condition memory cell.
In an embodiment of the present invention, the data of the intelligent memory of electric heater can be upgraded, be specially, when system detects any after end of extent, for example, at the time section of time zone 00:00～03:00, this time end of extent the moment for example 03:00 constantly the data memory before this time zone of this time period of this predetermined period is passed to the memory storage district of a predetermined period, example is as shown in table 1, using one week as a predetermined period, 8 time zones will be divided into every day of one week, to upgrade 8 secondary data every day of one week, when lower daystart, by the data zero clearing of upper one day, restart data memory new data more.When 00:00 finishes for one day constantly, store data, by the data zero clearing of next day, prepare to start to remember the data of next day.In addition, before each record data, the time period that all will read the corresponding predetermined period in electric heater, then the data of renewal are stored into the time zone of the corresponding time period of last predetermined period.If user cancels intelligent memory functional constantly, the data of intelligent memory will retain.If user carries out Default Value, all intelligent memory data are done zero clearing and are processed.After power-off, cannot detect discharge, so intelligent memory functional and Intelligent heating are all in disarmed state, if user has opened intelligent memory functional before power-off, after again powering on, system is automatically by the memory space data writing 0 in the corresponding time zone of the time period after power-off.
In sum, in one embodiment of the invention, open flow process that intelligent memory functional carries out intelligent memory as shown in Figure 2, comprise the following steps:
S201, judges whether user opens intelligent memory functional.
If opened intelligent memory functional, enter step S202, otherwise return.
S202, has judged whether user's water.
If judgement receives the instruction of user's water, user, at water, enters step S203, otherwise enters step S204.
S203, opens user's water timer, the recording user water time.
S204, judges whether current time zone finishes.
If so, enter step S205, if not, enter step S201.
S205, judges whether user's water timer time is greater than the first Preset Time and is less than the second Preset Time.
For example the first Preset Time is 3min, and the second Preset Time is 10min, judges whether the water timer time be greater than 3min and be less than 10min, if so, enters step S206, otherwise, enter step S207.
S206, the memory cell in current time zone is set to 1.
If the judgement water timer time is greater than 3min and is less than 10min, the memory cell in current time zone is set to 1, represent to receive the first instruction of user's water, a small amount of water of user detected.
S207, judges whether user's water timer time is more than or equal to the second Preset Time.
For example the second Preset Time is 10min, judges whether the time of user's water time timer record is more than or equal to 10min, if so, enters step S208, if not, enters step S209.
S208, the memory cell in current time zone is set to 2.
The time of user's water time timer record is more than or equal to for example 10min of the second Preset Time, and the memory cell in current time zone is set to 2, represents to receive the second instruction of user's water, a large amount of waters of user detected, and enters step S210.
S209, the memory cell in current time zone is set to 0.
By step S205 and S207, obtained when user's water timer time and be less than the first Preset Time for example during 3min, the memory cell in current time zone is set to 0, and expression does not have user's water.
S210, stores current time zone data into memory chip, and upgrades the data in the corresponding time zone of last predetermined period.
S211, judges whether the time of this time period finishes.
For example, using one week as a predetermined period, if this time period is this day on Sunday, judged whether to arrive the 00:00 on Sunday constantly, if so, entered step S212, otherwise return.
S212, arrives the corresponding time period of last predetermined period by the Data Update of this time period, and by the memory cell zero clearing of current this time period, opens the memory function of next time period.
