熱体への通電時間を集中制御する制御装置に関す
るものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a control device that centrally controls the energization time to the heating elements of a plurality of hot water storage type electric water heaters in a certain area, apartment, etc. by a central control device.
従来の深夜電力を利用する貯湯式電気温水器で
は、深夜電力の通電時間が一定であるため、発熱
体の発熱容量を湯の使用量の多い冬季の条件に合

温85℃程度に沸き上げるよう予め設定してある。
このため、湯の使用量の少ない夏季等では貯湯タ
ンク内に半分以上の湯が残ることが多い。この場

通電が始まり、短時間で沸き上がつてしまう。こ
れは通電開始からの数時間に通電負荷の集中を招
き、送電効率が悪くなるばかりか不必要に高温度
の湯を長時間使用に供さないで放置することとな
り、熱ロスが大きい欠点もあつた。 In conventional hot water storage type electric water heaters that use late-night power, the power-on time of late-night power is fixed, so the heat generating capacity of the heating element is adjusted to match the winter conditions when hot water consumption is high, so that the water temperature reaches 5 to 50% during the power-on time. It is preset to boil water from 10℃ to about 85℃.
For this reason, more than half of the hot water often remains in the hot water storage tank during the summer when the amount of hot water used is low. In this case, when the late-night power supply time arrives, the power supply starts all at once, and the power builds up in a short period of time. This not only leads to a concentration of the energized load in the first few hours after the power is turned on, which not only reduces power transmission efficiency, but also causes unnecessarily high-temperature hot water to be left unused for a long time, resulting in large heat loss. It was hot.
この発明は上記の点に鑑みてなされたもので、

Each of the multiple hot water storage type electric water heaters is equipped with a device that detects the water supply temperature, amount of remaining hot water, and temperature of remaining hot water to prevent boiling more water than necessary, and the central control device adjusts the energized load as appropriate. This allocation solves the above-mentioned conventional drawbacks.

℃, the detected value of the remaining hot water amount sensor 4 is v liters, and the detected value of the remaining hot water temperature sensor 5 is T2 , then the calculator A3 calculates K1 = ( T1 - t) x V (Kcal). Calculate the thermal calories K 1 that should be stored in the hot water storage tank. Also, arithmetic unit B6
The calculation is performed as follows: K 2 =(T 2 −t)×v(Kcal), and the thermal calorie K 2 remaining as the residual hot water is calculated.
