（従来技術）
従来の深夜電力を利用した貯湯式電気温水器において、
湯の使用量（使用湯量）は日々異なり。(Prior art) In the conventional hot water storage type electric water heater that uses late-night electricity,
The amount of hot water used (amount of hot water used) varies daily.
特に入浴の有無が使用湯量に与える影響は大きい。In particular, whether or not a person takes a bath has a large effect on the amount of hot water used.
例えば、入浴しない日は貯湯タンク容量の半分以上の湯
が残されることになる。そして、この場合は、不必要に
高い温度の湯が長時間使用に供されず、放置されること
となり、貯湯式タンク等からの放熱による熱損失がきわ
めて大きく、不経済となる問題があった。For example, on days when you do not take a bath, more than half of the hot water storage tank capacity will remain. In this case, unnecessarily high-temperature hot water would be left unused for a long time, resulting in extremely large heat loss due to heat dissipation from hot water storage tanks, etc., resulting in an uneconomical problem. .
この点に関して、定常的な使用湯量を設定するための定
常湯量設定手段と、１回限りの使用湯量を設定するため

可能に構成されたものが提案されている（例えば、特開
昭５８−１２４１４４号公報参照）。In this regard, it is equipped with a constant hot water amount setting means for setting the constant amount of hot water used and a provisional hot water amount setting means for setting the amount of hot water used only once. A system has been proposed in which the difference in required heat amount can be corrected only on the next day after the set date (for example, see Japanese Patent Laid-Open No. 124144/1983).
しかしながら、このような構成においても、暫定湯量設
定手段により予め設定できるのは翌日分のみで、翌々日
は定常湯量の運転にもどるため。However, even in such a configuration, the provisional hot water amount setting means can only set the amount for the next day in advance, and the operation returns to a constant hot water amount the day after the next day.
度々暫定湯量設定手段を設定操作する必要がある。It is necessary to frequently set the provisional hot water amount setting means.
