Next, the operation of the conventional example having the above configuration will be explained. When the midnight power supply start time arrives, the contact of the time switch 8 is closed and the supply of electricity to the heating element 5 is started. When the temperature of the hot water in the hot water storage tank 1 reaches 85° C., the contacts of the automatic temperature regulator 6 are opened and the power supply to the heating element 5 is stopped.

Thereafter, the temperature of the water is maintained at 85°C by opening and closing the automatic temperature controller 6, and in this way, the entire amount of stored hot water is boiled to 85°C every morning.

In this manner, in order to increase hot water storage efficiency, the hot water storage type electric water heater has a structure in which the rising temperature is set as high as possible, and heating is stopped when the set temperature is reached. However, users do not use high-temperature hot water as it is, but mix it with water and use it as a mixed hot water at around 40 to 45°C. The formula for calculating the amount of mixed hot water obtained is as follows.

Now, let the hot water storage tank capacity be Vt (u), and the boiling temperature in hot water storage tank 1 be T. ('O), the temperature of the mixed hot water to be obtained is Tm ('O), the temperature of the water to be mixed (water supply temperature) is Ti (°O), the amount of mixed hot water Vm (

In this formula, the water supply temperature Ti varies greatly depending on the season. In Tokyo, the temperature ranges from around 5°C in winter to around 27°C in summer. Therefore, the amount of hot water that can be obtained as mixed hot water at an appropriate temperature is small in the winter and large in the summer. That is, the boiling temperature T. 85°C, the amount of mixed hot water Vm obtained when the water supply temperature T1 is 27°C is 1.6 times that when the water supply temperature T1 is 5°C.

On the other hand, the amount of hot water used is approximately constant throughout the year, or in fact, the actual amount used generally decreases in the summer because hot water is used at a lower temperature, and the amount of hot water remaining in the summer is larger than in the winter. . Furthermore, due to a decrease in the number of families, many users use only 1/2 of the rated capacity, or 2/3, leaving a large amount of hot water every day.

このように、給水温度が高かったり残湯があると、沸き

In this way, if the water supply temperature is high or there is residual hot water, the hot water will boil quickly and the hot water will be left unused for a long time.

This invention attempts to eliminate these drawbacks.
Equipped with an input device for setting the next day's hot water usage status step by step, for example, "to take a bath,""to not take a bath," etc., and past usage stored in the storage device for each set step. Based on the conditions, we perform optimal boiling with a reduced amount of remaining hot water, and level out the power supply to the heating element over the entire time from the start of late-night power supply until the end of power supply, thereby reducing heat. The aim is to eliminate loss as much as possible.

An electric water heater that uses late-night electricity to energize a heating element to heat water in a hot water storage tank, includes a temperature detection means for detecting the temperature of water supplied to the hot water storage tank and the boiling temperature, and a temperature detection means for detecting the temperature of water supplied to the hot water storage tank and the temperature at which the water is boiled, and the amount of water scheduled to be used on the next day. An input device for inputting data, a storage device for storing the input from the input device and the actual energization time as data, and a storage device that calculates the required amount of energization power to the heating element based on the data, and calculates the amount of power to be energized to the heating element, and calculates the feed water temperature 1. A calculation device that calculates the boiling water temperature from the amount of energized electricity and the capacity of the hot water storage tank, and the amount of electricity supplied to the heating element between the start and end of supply of late-night electricity to the required amount of energized electricity determined by the calculation device. an energization rate control device that controls power supplied to the heating element so as to match; and energization of the heating element when the boiling water temperature detected by the temperature detection means reaches the boiling temperature calculated by the calculation device; and an energization power amount calculation device that calculates the amount of energized power to the heating element and inputs the value into the storage device to update the data. A control device for a hot water storage type electric water heater.
