この発明は貯湯式電気温水器に関するもので、
使用湯量、給水温度及び貯湯タンク内の残湯の状
態から適正な発熱体容量を算出して常に一定時間
で沸上げるようにするものである。[Detailed Description of the Invention] This invention relates to a hot water storage type electric water heater.
The system calculates the appropriate heating element capacity from the amount of hot water used, the water supply temperature, and the state of the remaining hot water in the hot water storage tank, and always boils the water in a fixed amount of time.
第１図は一般的な貯湯式電気温水器の構成図
で、第２図は従来の貯湯式電気温水器の主要電気
回路図を示す。 FIG. 1 is a block diagram of a general hot water storage type electric water heater, and FIG. 2 is a main electrical circuit diagram of a conventional hot water storage type electric water heater.
図において、１は貯湯タンク、２は発熱体、３
は自動温度調節器、４は電源である。 In the figure, 1 is a hot water storage tank, 2 is a heating element, and 3
is an automatic temperature controller, and 4 is a power supply.
次に一般に行われている深夜電力を利用した場
合を例にその作用動作を説明すると、発熱体２は
深夜電力通電時間内に冬期の水温に相当する８℃
前後の水を約85℃に沸上げるようにその発熱体容

閉の接点を有しており、貯湯タンク１内の水が約
85℃になると接点を開成して発熱体２への通電を
停止させるように構成されており、貯湯タンク１
内には毎朝85℃の湯が満たされている。 Next, to explain the function and operation using the general case of using late-night power as an example, the heating element 2 is heated to 8°C, which corresponds to the water temperature in winter, during the late-night power supply time.
The capacity of the heating element is set to boil the water before and after it to approximately 85℃. In addition, the automatic temperature controller 3 has a normally closed contact point, so that the water in the hot water storage tank 1 is approximately
It is configured to open a contact and stop supplying electricity to the heating element 2 when the temperature reaches 85°C, and the hot water storage tank 1
The interior is filled with hot water at 85℃ every morning.
しかし、湯の使用量は常に同じとは限らず、
日々大きくは季節によつて異なつている。特に入
浴の有無は湯の使用量を大きく左右する要素とな
り、入浴しない日は貯湯量の半分以上の湯を残す
ことにもなる。 However, the amount of hot water used is not always the same.
Day-to-day differences vary greatly depending on the season. In particular, whether or not a person takes a bath is a factor that greatly influences the amount of hot water used, and on days when a person does not take a bath, more than half of the stored hot water may remain.
従つて残湯がある場合には深夜電力通電時間に
なると一斉に通電が始まり短時間で沸上がつてし
まう。このため、電力負荷の集中が起こり、深夜
電力の本来の目的である電力負荷の均一化が図れ

られた高温湯を長時間使用に供さないで放置する
ことになり、貯湯タンク１からの自然放熱及び配
管内に滞留した温水の放熱等による熱ロスが大き
くなるという欠点を有していた。 Therefore, if there is any remaining hot water, the electricity will start all at once when the electricity is turned on late at night, and the water will boil in a short time. As a result, the power load is concentrated, making it impossible to equalize the power load, which is the original purpose of late-night power, resulting in poor power transmission efficiency, and the hot water that has been boiled cannot be used for a long time. This has the drawback of increasing heat loss due to natural heat radiation from the hot water storage tank 1 and heat radiation from hot water stagnant in the piping.

In FIG. 3, 12 is a constant hot water amount setting device for presetting the next day's amount of hot water stored in the hot water storage tank 1, and 14 is a provisional hot water amount setting device for similarly setting the amount of hot water for one-time use. Generally, it is set by the steady hot water amount setting device 12, but for example, if you do not take a bath the next day or do not use hot water, the provisional hot water amount setting device 1 is used.
The amount of hot water used is set by the operation 4, and the value set by the constant hot water amount setting device 12 is automatically restored two days later.

リーK1（Kcal）を算出する。 Next, an example of the operation of the above configuration will be explained using symbols and formulas. First, steady water amount setting device 12
Alternatively, the amount of hot water used on the next day inputted by the provisional hot water amount setting device 14 is set as V liters (water temperature T 1 degree),
Assuming that the detected value of the water supply temperature sensor 5 immediately after the late-night power supply period starts, the detected value of the remaining hot water amount sensor 7 is V liters, and the detected value of the remaining hot water temperature sensor 8 is T 2 degrees, the computing unit A6 calculates K 1 =(T 1 -t)V is calculated, and the thermal calorie K 1 (Kcal) 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 is calculated.
また演算器Ｂ９は、

ともないので、放熱ロスを少なくできるものであ
る。さらに湯量設定は、定常的なものと暫定的な

なるものである。 Based on K 1 and K 2 calculated by the arithmetic unit A6 and the arithmetic unit B9, the arithmetic unit C10 calculates P=K 1 -K 2 /860, and calculates the amount of water that should be stored in the hot water storage tank 1. The required heating element capacity P (KW) is calculated from the net heat calories to be applied, excluding the heat calories K2 held by the remaining hot water from the heat calories K1 of the amount of hot water. (1K.WH=860Kcal) Next, the required heating element capacity P is determined by the computing unit C10.
(KW) is calculated, the amount of electricity applied to the heating element 2 is controlled by the power control device 11, and a predetermined amount of electricity is added for the entire late-night power supply time, and at the same time as the late-night power supply time ends. Boiling is controlled to end. Therefore, the greater the amount of hot water remaining in the hot water storage tank 1 and the higher the temperature of the remaining hot water, the lower the amount of electric power required by the heating element 2, and the amount of electric power required is always averaged over the entire late-night power supply period. Therefore, the concentration of power load is alleviated, and since hot water is not left in the hot water storage tank 1 for a long time, heat radiation loss can be reduced. Furthermore, since the hot water amount setting can be set appropriately between a constant setting and a temporary setting, maintenance costs are also reduced.
なお、上記動作例では深夜電力利用の場合につ
いて説明したが、一般電力用として沸上がり希望
時刻を入力できるタイマー機構を設けても同様の
効果を得ることができる。 In the above operation example, the case of using late-night power has been described, but the same effect can be obtained even if a timer mechanism is provided for inputting the desired boiling time for general power.

なるという効果を有している。 As described above, the present invention includes a steady hot water amount setting means for presetting the amount of hot water used on a regular basis to be stored in the hot water storage tank, a provisional hot water amount setting means for setting the amount of hot water used only once, and a temporary hot water amount setting means for setting the amount of hot water used only once, and a calculation means A that calculates the thermal calories of the hot water to be stored from the set value set by the hot water amount setting means and the detected value detected by the water supply temperature detection means; A remaining hot water amount detecting means for detecting the amount of hot water remaining in the hot water storage tank, a remaining hot water temperature detecting means for detecting the temperature of the remaining hot water in the hot water storage tank, and a remaining hot water thermal calorie calculated from each detection value detected by each of the detection means. a calculation means B; a calculation means C that calculates the required heating element capacity from the difference in heat calories calculated by the calculation means A and calculation means B; It is equipped with a power control means that controls the amount of electricity supplied to the body, detects the temperature of water supplied to the hot water storage tank, the amount of remaining hot water, and the temperature of the remaining water, calculates the required thermal calories, calculates the capacity of the heating element, and then applies electricity. Since it is configured to apply electricity in an average manner over a time period and only apply heat calories that match the amount of hot water used, it is possible to equalize the electric power load and improve power transmission efficiency. In addition, not only can you set the constant amount of hot water, but you can also set the amount of hot water temporarily, which reduces the amount of hot water left each day, improves usability, and eliminates the need to leave hot water in hot water for long periods of time. This has the effect of reducing heat radiation loss and lowering maintenance costs.
