Next, the control operation in the above configuration will be explained based on FIG. 2. Based on the information from the timer/calendar 2, the control calculation unit 1 stores the memory A at the midnight power start time of 23:00 every day in step S1.
3, the day of the week setting data is read out, and it is confirmed whether the current day is a preset day of the week. If the current day is the set day of the week (Y), the amount of remaining hot water for that day is stored in the memory A3 in step S2. On the other hand, if it is a day of the week for which this is not set (N), the remaining amount of hot water for that day is stored in the memory B4. Next, in step S4, it is determined whether or not it is the previous day of the set day of the week, and if it is the set day of the week (Y), in step S5, the amount of remaining hot water on the same day of the past and the amount of boiling water are stored in memory A3. Read the energization time data,
The boiling temperature is determined from these data. On the other hand, if it is the day before the day of the week that has not been set (N), step S6
The data for the past six days (excluding the set days of the week) are read from memory B4, and the boiling temperature is determined in the same way. The boiling temperature Ts is calculated using the following formula: Ts=(860×P×η×Hs)/V+Tw+α
Here, V: Capacity of hot water storage tank (l) P: Rated power consumption of electric heater 5 (kW) Hs: Average of past boiling energization time (h) η: Heating efficiency of electric heater 5 Tw: Supply city water temperature (℃) α: Margin temperature for boiling water amount (℃) Also, 23:0
Time Hp from 0:00 to the time when the electric heater 5 is turned on
is calculated by the following formula: Hp=H-(Ts-Tw-α
)×V/(860×P×η) Here, H: Contract usage time of late-night electricity (h) and 2
When Hp time has passed from 3:00, the electric heater 5 is turned on in step S7, and the hot water temperature in the hot water storage tank reaches Ts.
When this happens, the heater 5 is turned off to complete boiling. Next, in step S8, when the boiling is completed, it is determined whether or not it is the next day of the set day of the week, and if it is the next day of the set day of the week (Y), in step S9, the memory A
On the other hand, if it is the next day on a day that is not set (N), the boiling energization time is stored in the memory B4 in step S10. By repeating the above process every day, the desired purpose can be achieved.

[Effects of the Invention] As explained above, according to the present invention, when the user sets the electric heater energization time and boiling temperature for the day, the user can set the specific days of the week such as weekdays and holidays, respectively. This type of electric water heater can be used more conveniently and economically because the boiling operation is performed according to the amount of hot water used for the day of the week.
