この発明は、各ユーザーの住戸内などにおけるエネルギー管理を行うことのできる給湯機および給湯システムに関するものである。
【０００２】
【従来の技術】
従来の技術について、説明を行う。
従来の給湯機は、蛇口を開けば、いつでもお湯が使え、流量も蛇口の開度により、給湯機の能力限界まで自由に使用できる。
【０００３】
【発明が解決しようとする課題】
従来の給湯機は以上のように、機器の能力限界はあるにしろ、ユーザーが好きなときに、好きな設定で、好きな時間だけ機器を使え、非常に利便性の高いものであった。
ところが、一方で、お湯を出しっぱなしで入浴したりと、エネルギー消費面で、ムダが発生したとしても、機器側からは、制限がなかった。
【０００４】
ここで、地球規模でみれば、地球温暖化防止を行うことは、緊急課題となっている。地球温暖化防止の為に、ＣＯ２ 排出量を抑制していくことが早急に必要であり、その対応として、機器の省エネ化，物流システムの改善等が必要であるが、それだけでは２０１０年に向かった計画は達成できず、国民の省エネ努力が不可欠となっている。

【００１２】
次に、図１から図３により、給湯機２の動作の説明を行う。
給湯機２を使用して各蛇口及びシャワー１１０，１１１，１１２から給湯を行う場合について説明する。
【００１３】
ここで、ユーザーがリモコン１２１の操作部４に設けた給湯最高流量設定スイッチ５１，５２を操作し給湯最高流量を１０Ｌに設定すると、制御部１２０および住戸内制御装置３は、流量調整弁１０８を絞るように作動させて、給湯負荷１１０，１１１，１１２への給湯時に、給湯流量が１０Ｌ／分以上出ないように制御する。

これにより、必要以上に給湯湯温を高くすることがないため、配管の放熱ロスを低減させ、省エネになるとともにＣＯ２ 排出量を押えることができる効果がある。
【００１６】
さらに、ユーザーが操作部４の沸き上げ最高湯温設定スイッチ５７，５８を操作し沸き上げ最高湯温を８０℃に設定すると、制御部１２０および住戸内制御装置３は、給湯機リモコン１２１の沸き上げ湯温設定の上限値を８０℃とし、貯湯槽１０２内の沸き上げの最高湯温に制限を与える。
これにより、必要以上に沸き上げ湯温を高くすることがないため、貯湯槽からの放熱ロスを低減させ、省エネになるとともにＣＯ２ 排出量を押えることができる効果がある。
【００１７】
ここで、給湯機は電気式のいわゆる電気温水器だけでなく、石油式の給湯機やガスによる給湯機なども含まれる。
【００１８】
また、ユーザーによる操作部４の設定かわりに、外部制御装置５から電話回線６経由で、操作部４と同じ設定を行うこともできる。例えば、外部制御装置は、地方自治体などに設置することが可能であり、公共の立場から、住戸内の機器を制御することが可能となる。また、電話回線６には、無線を使用することも可能である。
これにより、公共の第三者が、すべての家庭の住戸の機器を制御することができ、地球規模で一般家庭の省エネを促進するとともにＣＯ２ 排出量を押えることができる。
【００１９】
また、本システムでは、一般家庭の住戸を対象にシステムを示したが、一般住戸だけでなく、集合住宅全体やオフィスビル，工場，病院などのエネルギー負荷制御として、対応が可能である。
【００２０】
【発明の効果】
第１の発明に係る給湯機によれば、シャワーなどで必要以上に給湯流量を上げて使用することがなくなり、省エネになるとともにＣＯ２排出量を押えることができる効果がある。
また、シャワーなどで出しっぱなしで使用するような使い方に制限を与えることで、省エネになるとともにＣＯ２排出量を押えることができる効果がある。さらに、必要以上に給湯湯温を高くすることがない為、配管の放熱ロスを低減させ、省エネになるとともにＣＯ２排出量を押えることができる効果がある。
