である。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a central control device that 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.
第1図は一般的な貯湯式電気温水器の構成図

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

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 operation using a case where late-night power is generally used as an example, the heating element 2 heats up to 8 ℃, which corresponds to the water temperature in winter, during the late-night power supply time.
The capacity of the heating element is preset to boil water around 85°C. The automatic temperature controller 3 has a normally closed contact, and is configured to open the contact and stop supplying electricity to the heating element 2 when the water in the hot water storage tank 1 reaches approximately 85°C. 1 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.
しかるに、従来においては、残湯の有無に関係
なく、深夜電力の通電時間になると一斉に発熱体
への通電が始まり、常に一定の湯量を沸き上げて
いる。このため、通電開始直後からの数時間は電

ある電力負荷の均一化が図れず、送電効率も悪い
結果を招くとともに、入浴しない日や夏期におい
ては多量の湯が使用に供さないで残されることに
なり無駄が大きいという欠点を有していた。 However, conventionally, regardless of the presence or absence of residual hot water, electricity is turned on to the heating elements all at once at the midnight power turn-on time, and a constant amount of hot water is always boiled. For this reason, the power load is concentrated for several hours immediately after the power supply starts, making it impossible to equalize the power load, which is the original purpose of late-night power, and resulting in poor power transmission efficiency. This method had the disadvantage that a large amount of hot water was left unused, resulting in a large amount of waste.
この発明は上記の点に鑑みてなされたもので、
複数の貯湯式電気温水器の各々に使用湯量を予め
設定できる装置を設けて必要以上の湯量を沸き上

欠点を解消するものである。 This invention was made in view of the above points,
By installing a device that can preset the amount of hot water used in each of the plurality of hot water storage type electric water heaters to avoid boiling more water than necessary, and by appropriately distributing the energizing load using the central control device, the above-mentioned conventional method can be improved. This is to eliminate the shortcomings.

えておくべき熱カロリーKを算出する。 The steady water amount setting device 6, 6' and the provisional hot water amount setting device 7, 7' are similar hot water amount setting devices, but the former is a device that constantly sets the boiling amount and is generally intended for bathing. On the other hand, the latter is a device that temporarily sets the amount of hot water used when the user does not take a bath or does not use hot water at all, which is much lower than when the amount of hot water used is steady, and normally the steady water amount setting devices 6 and 6' are in operation. In this state, if the temporary hot water amount is set using the temporary hot water amount setting devices 7 and 7',
For one day only, the temporary hot water setting is used to boil the water, and the next morning when boiling is complete, the provisional water setting is automatically canceled and the system returns to the regular hot water setting. First, the set values for the amount of hot water to be used on the next day input into the constant hot water amount setting device 6, 6' or temporary hot water amount setting device 7, 7' of each electric water heater 5, 5' are set as V liters and hot water temperature T°C, and the late-night power consumption is If the detected value of the water supply temperature sensor 8, 8' immediately after the start of the energization time is t°C, the calculator 9, 9' calculates K=(T-t)×V (Kcal). Calculate the thermal calories K that should be stored within 1.1'.

1, 11'. Power supply controller 11 of each machine,
11' controls the energization time of the heating elements 2, 2' based on a signal from the central transmitter 15. For example, in a certain area or condominium, if 200 electric water heaters are each powered for 3 hours to obtain the specified amount of electricity, 100 units will be powered on from 11pm to 2am the next morning, and the other 100 units will be powered on from 11pm to 2am the next morning. The electricity is distributed from 2:00 to 5:00 the next morning to keep power peaks as low as possible.

る。 As explained above, in the present invention, each of the plurality of hot water storage type electric water heaters is equipped with a hot water amount setting device that can appropriately select between a constant hot water amount setting and a provisional hot water amount setting. In addition to eliminating the need for electricity to be wasted by boiling only the amount of water, the central control unit aggregates the required energization time for each electric water heater and distributes it to each electric water heater so that the power load is averaged. Since the power is distributed, peak power loads can be alleviated, which has the effect of significantly improving power transmission efficiency.
