[Detailed Description of the Invention] The present invention relates to a control device for a hot water storage type electric water heater that uses late-night electricity, which grasps the water supply temperature and the amount of heat remaining in the hot water and applies it to the heating element for a preset amount of hot water used. To reduce the amount of remaining hot water and heat loss after boiling by calculating the required energization time and controlling the start time of energization to the heating element so that the energization time is obtained at the same time as the end of the energization time of late-night electricity. It is an object.

In the figure, 1 is a hot water storage tank, 2 is a heating element, and 3
is an automatic temperature controller, 4 is a power supply, and 5 is a time switch for late-night power.
From 11pm to 7am the next morning.

Next, the function and operation will be explained. When the midnight power supply start time arrives, the contact of the time switch 5 is opened and the supply of electricity to the heating element 2 is started. and,
When the temperature of the hot water in the hot water storage tank 1 reaches 85 [° C.], the contacts of the automatic temperature controller 3 are opened and the electricity to the heating element 2 is stopped. In this way, the entire amount of hot water is stored every morning.
It's boiling to 85 degrees Celsius.

However, the amount of hot water used is not always the same, and varies greatly from day to day and depending on the season. In particular, whether or not a person takes a bath is a factor that greatly influences the use of hot water, and on days when a person does not take a bath, more than half of the stored hot water may remain. Additionally, depending on the season, the temperature of the water supply has a large effect on the amount of hot water that can be extracted, and in the summer when the water supply temperature is high, a larger amount of hot water can be extracted at the appropriate temperature than in the winter.

On the other hand, the amount of hot water used is almost constant throughout the year, or rather, the actual amount used is generally lower because the water is used at a lower temperature in the summer, and the hot water temperature in the summer is higher. Therefore, if the water is hot enough, it will boil in a short time.

In addition, since the power supply to the heating elements 2 starts all at once at the time when the late-night power is applied, the power load is concentrated immediately after the power supply starts, and the original purpose of the late-night power is to equalize the power load. This has the disadvantage that the high temperature water heated in the hot water storage tank 1 is left unused for a long time, and heat loss due to natural heat dissipation increases. Ta.

Furthermore, conventional hot water storage type electric water heaters are not equipped with a device for detecting the amount of heat of remaining hot water, and only some of them have been equipped with devices that detect the amount of remaining hot water.

However, this method of detecting the amount of remaining hot water was also a step-by-step method in which multiple temperature sensors, such as thermostats and thermistors, were lined up on the outer wall of the hot water storage tank to detect temperature changes at those locations.

このため、検出された残湯量もそれ程精度の高

For this reason, the detected amount of remaining hot water was not a very accurate value, and in many cases it was simply used as data for the next boiling.

The present invention aims to solve these drawbacks by making it possible to set the regular amount of hot water used and the temporary amount of hot water used in advance, and adjusting the water supply temperature and the temperature in the hot water storage tank based on the preset amount of hot water used the next day. Calculating the required energization time to the heating element with reference to the detected value of the residual water heat value, and controlling the time to start energizing the heating element so that the required energization time can be completed at the time when the late-night power supply ends. This aims to reduce the amount of remaining hot water and eliminate heat loss after boiling as much as possible.

First, before entering the late-night power-on period, the user inputs the amount of hot water used for the next day.
Here, let us assume that the amount of hot water used on the next day inputted by the user using the steady hot water amount setting device 6 or temporary hot water amount setting device 7 is V [ ] (hot water temperature T [°C]), and the water supply temperature sensor 8 immediately after entering the late night power supply time period is The detected value is t
[°C], the calculator A9 calculates K 1 = (T-t) x V (Kcal) to calculate the calorific value of the amount of hot water that should be stored in the hot water storage tank 1 by the end of the late-night power supply time.
Calculate K 1 [Kcal].

That is, in this state, the lower part 1a of the hot water storage tank is filled with water from the water supply pipe 14 for the amount of hot water V 1 [] used.
[°C] Water flows in, and the upper part 1b of the hot water storage tank has T 1
There is still V 2 [℃] hot water left. In this state, when the circulation pump 17 is operated with the faucet 16 closed, the water in the lower part 1a of the hot water storage tank flows into the communication pipe 18.
Since the hot water flows from the upper part 1b of the hot water storage tank through the hot water storage tank and stirs the hot water layer in the upper part 1b of the hot water storage tank, the temperature of the hot water gradually becomes average.
