Communication means 97. Further, there is provided a notifying unit 98 for notifying or issuing a warning to the user based on the detection result of the remaining hot water amount detection unit 96. [0009] The remote controller 71 sets a current time and counts the time. When the current time measured by the clock function unit 201 is in the daytime (for example, from 7:00 to 23:00). , A full-boiler switch that is turned on when instructing the lower heater 33 to be energized, and the upper heater 3
4, a daytime boiling operation unit 202 having a small amount boiling switch that is turned on when instructing the power supply to the power supply 4;
Setting values such as the hot water supply temperature set by
Display unit 20 for displaying operating information such as the amount of remaining hot water detected in step 20

And communication means 208 for mutually communicating with the main body control section 70 the set temperature information, the operation information of the electric water heater 100 and the like set in the above. According to the above configuration, when it is recognized that the current time measured by the clock function unit 201 of the remote controller 71 is in the midnight time zone (for example, from 23:00 to 7:00 the next day), the heater control unit 95 However, the lower heater 33 is instructed to energize so that the boiling ends at the end time of the late night time zone, and the total amount of water in the hot water storage tank 32 (for example, 370)
Liters) by the midnight electric power tank first temperature sensor 3
7 is heated until the set temperature set by the temperature setting unit 205 of the remote controller 71 is detected. In addition, it is necessary to calculate the boiling start time in order to end the boiling in accordance with the end time of the late night time zone, for example, calculate the residual hot water calorie based on the detected temperature of the tank temperature sensor and the like. Calculate the amount of heat required for boiling from the remaining hot water calorific value, calculate the time required to boil the required calorific value, and calculate the time from the end time of the midnight time zone to the time required to go back to the required time and the boiling start time. Various methods are conceivable. When a hot water tap (not shown) connected from the electric water heater 100 via the hot water supply pipe 8 is opened, hot water in the boiling hot water storage tank 32 is discharged. The temperature of the spouted water can be set by the temperature setting unit 205 according to the application and preference. The hot water in the hot water storage tank 32 is supplied to a bathtub 62.
In the case of using for hot water, the hot water switch of the hot water operation unit 206 is turned on. The hot water temperature at this time can be set according to the preference by the hot water temperature setting switch of the temperature setting section 205, and the hot water quantity can be set according to the bathtub capacity by the hot water quantity setting switch of the hot water operating section 206. It is. When hot water is used in the hot water storage tank 32, water is supplied from the lower part of the hot water storage tank 32 and the amount of remaining hot water decreases, so that the user needs to use the hot water while checking the remaining hot water amount. Therefore, for example, the total capacity of the hot water storage tank 32 is set to 37
0 liter, the tank first temperature sensor 37 at a position where the capacity from the top of the hot water storage tank 32 is 300 liters,
The tank second temperature sensor 38 at the position of 150 liters,
The tank third temperature sensor 39 at the position of 100 liters,
Assuming that the tank fourth temperature sensor 40 is mounted at the position of 50 liters, the remaining hot water amount detected by the remaining hot water amount detection unit 96 based on the detected temperature of each sensor (for example, it is determined that there is remaining hot water if the temperature is 45 ° C. or more). 300 liters or more, remaining hot water volume 150 liters or more and less than 300 liters, remaining hot water volume 10
The remaining hot water amount information such as 0 liters or more and less than 150 liters, the remaining hot water amount of 50 liters or less and less than 100 liters, or the remaining hot water amount of less than 50 liters is displayed on the display unit 204 of the remote controller 71 in a numerical value or picture display so that the remaining hot water amount can be confirmed. It is. Then, when the amount of hot water used by the visitor becomes large and the amount of hot water is likely to be insufficient, the total amount of water in the hot water storage tank 32 is increased by turning on the switch and turning on the switch even in the daytime.
By turning on a small boiling switch, a small amount of water (for example, 100 liters) in the hot water storage tank 32 can be boiled. Next, the operation of the electric water heater according to one embodiment of the present invention will be described with reference to FIG. First, step S1
It is determined whether or not the hot water switch is on. If it is determined that the hot water switch is on, it is determined whether or not there is a possibility of running out of hot water during the hot water (step S2). here,
The determination as to whether or not there is a possibility of running out of hot water is made by a thermistor (e.g., the third temperature sensor 3
It is determined whether the temperature of 9) is equal to or higher than 20 ° C. with respect to the temperature set by the hot water temperature setting switch of the temperature setting unit 205. If the temperature is lower than 20 ° C., running out of hot water may occur. It is determined that there is a possibility. Alternatively, the possibility of running out of hot water may be determined based on the temperatures detected by the tank first temperature sensor 37, the tank second temperature sensor 38, the tank third temperature sensor 39, and the tank fourth temperature sensor 40. Then, when it is determined in step S2 that there is a possibility of running out of hot water, an alarm for running out of hot water and an operation for increasing the amount of hot water are performed.
For example, a voice message such as "There is a possibility that the hot water runs out before the end of the hot water beam. Please operate the additional heating switch" (step S3). Step S2
When it is determined that there is no possibility of running out of water, the process returns to step S1. Therefore, when there is a possibility of running out of hot water during hot water filling, when the hot water filling operation is performed, the user is notified of the fact, and the boiling operation is performed so that hot water is not generated. Because it is encouraged, the hot water does not run out when the hot water is filled.
