According to some embodiments of the present invention, the working cycle can be seven, and each working cycle can have seven days, can be divided into six time periods every day, and within each cycle, predetermined number of days N=(X-1) × 4。
For example, within second working cycle, predetermined number of days N is 4, it is to say, enter second working cycle, it is judged that seven days in the first job cycle in section at the same time the natural law of water outlet whether more than 4 days, if, then this time period is labeled as the regular time period, if it is not, then this time period is labeled as the irregular time period。
Within the 3rd working cycle, predetermined number of days N is 8, judge 14 days in first to second working cycle in section at the same time the natural law of water outlet whether exceed predetermined number of days 8, and judge that between the time period of adjacent two water outlet, whether institute's interlude number more than 24 hours is more than 4, if two conditions are all satisfied, then this time period is labeled as the new regular time period, if one in two conditions is unsatisfactory for, then this time period is labeled as the new irregular time period。
Again such as, within the 4th working cycle, predetermined number of days N is 12, it is judged that first condition: whether the water outlet natural law in section at the same time of many days in first to the 3rd working cycle exceedes predetermined number of days 12。And judge second condition: between the time period of two adjacent water outlets, institute's interlude exceedes whether the number of certain time exceedes predetermined number respectively, specifically, judge that between the time period of adjacent two water outlet, whether institute's interlude number more than 24 hours is more than 8, and judge that between the time period of adjacent two water outlet, whether institute's interlude number more than 48 hours is more than 4。If first condition and second condition are all satisfied, then this time period is labeled as the new regular time period, if any one in first condition and second condition is unsatisfactory for, then this time period is labeled as the new irregular time period。
Within the 5th working cycle, predetermined number of days N is 16, it is judged that first condition: whether the water outlet natural law in section at the same time of many days in first to the 4th working cycle exceedes predetermined number of days 16。And judge second condition: between the time period of two adjacent water outlets, interlude exceedes whether the number of certain time exceedes predetermined number respectively, specifically, judge that between the time period of adjacent two water outlet, whether institute's interlude number more than 24 hours is more than 12, judge that between the time period of adjacent two water outlet, whether institute's interlude number more than 48 hours is more than 8, and judge that between the time period of adjacent two water outlet, whether institute's interlude number more than 72 hours is more than 4。If first condition and second condition are all satisfied, then this time period is labeled as the new regular time period, if any one in first condition and second condition is unsatisfactory for, then this time period is labeled as the new irregular time period。
Within the 6th cycle, predetermined number of days N is 20, it is judged that first condition: whether the natural law of water outlet in section at the same time of many days in first to the 5th working cycle exceedes predetermined number of days 20。And judge second condition: between the time period of two adjacent water outlets, interlude exceedes whether the number of certain time exceedes predetermined number respectively, specifically, judge that between the time period of adjacent two water outlet, whether institute's interlude number more than 24 hours is more than 16, judge that between the time period of adjacent two water outlet, whether institute's interlude number more than 48 hours is more than 12, judge that between the time period of adjacent two water outlet, whether institute's interlude number more than 72 hours is more than 8, and judge between adjacent two water outlet that between section, whether institute's interlude number more than 96 hours is more than 4。If first and second condition all satisfied, then changing the time period is labeled as the new regular time period, if any one in first condition and second condition is unsatisfactory for, then this time period is labeled as the new irregular time period。
Within the 7th cycle, predetermined number of days N is 24, it is judged that first condition: whether the natural law of water outlet in section at the same time of many days in first to the 6th working cycle exceedes predetermined number of days 24,。And judge second condition: between the time period of two adjacent water outlets, interlude exceedes whether the number of certain time exceedes predetermined number respectively, specifically, judge that between the time period of adjacent two water outlet, whether institute's interlude number more than 24 hours is more than 20, judge that between the time period of adjacent two water outlet, whether institute's interlude number more than 48 hours is more than 16, judge that between the time period of adjacent two water outlet, whether institute's interlude number more than 72 hours is more than 12, judge between adjacent two water outlet that between section, whether institute's interlude number more than 96 hours is more than 8, and judge between adjacent two water outlet that between section, whether institute's interlude number more than 120 hours is more than 4。If first and second condition all satisfied, then changing the time period is labeled as the new regular time period, if any one in first condition and second condition is unsatisfactory for, then this time period is labeled as the new irregular time period。
Thus, record 49 days altogether, the use regimen condition such as heat time heating time of namely 7 weeks, temperature retention time, water consumptions etc. judge, think and namely think regular more than 4/7 in same logic, no matter its regular intervals how far, thus the water habits of user is carried out reductive analysis according to various modes, the reproduction user all water habits to be formed in week age at most, and truly have the time period of custom that electric heater is carried out heating intelligent control according to the rule found user, ensure that user can have hot water to use within the time period of oneself custom water to greatest extent, within the time period that user does not have water habits, reduce hot water amount simultaneously as far as possible, save the energy。
Alternatively, six time periods of every day can respectively 2 .-6 points, 6 .-10 points, 10 .-14 points, 14 .-18 points, 18 .-22 and 22 .-2 points。Thus, it is possible not only to divide every day according to the water habits of major part user, realize fuzzy rule to a certain extent to find, allow user's to use water behavior not accurate, the adaptivity of computer heating control can be improved, and the insulation time-delay characteristics of electric heater can be made full use of, it is ensured that there is hot water in the time period of user habit water, energy consumption can be reduced simultaneously。
In some embodiments of the invention, the span of predetermined temperature T1 can be 70 degree～80 degree, for instance, predetermined temperature T1 can be 75 degree。The span of predetermined amount of water V1 can be 1/2 × V0～V0, and wherein V0 is inner bag volume, if the span that inner bag volume is 100L, predetermined amount of water V1 can be 50L～100L, for instance, predetermined amount of water V1 can be 80L。Within the first job cycle, control, in electric heater, there is the water that 80L temperature is 75 degree, thus ensureing that user has hot water to use within second working cycle。
