【０００１】
【発明の属する技術分野】
本発明は、浴槽を備えた浴室内を暖房する浴室暖房機と、この浴室暖房機の作動を制御する暖房制御手段と、前記浴槽内の湯水を追焚きする追焚き手段と、前記浴槽内の湯水の温度が設定温度になるように前記追焚き手段の作動を制御して適温キープ運転を実行する風呂制御手段とを備えている浴室暖房機付き給湯装置に関する。
【０００２】
【従来の技術】
このような浴室暖房機付き給湯装置においては、従来、浴室暖房機の作動は暖房制御手段により、追焚き手段の作動は風呂制御手段により、そのぞれ独立して制御されており、また、風呂制御手段による適温キープ運転は、予め設定された時間経過毎に開始して実行されるように構成されていた。
【０００３】
【発明が解決しようとする課題】
このように、従来においては、適温キープ運転が実際の入浴時とは無関係にある設定時間毎に開始されていたので、入浴の際に必ずしも浴槽内の湯温が適温に維持されているとは限らず、適温よりかなり低い湯温の場合もあり、この点に改良の余地があった。
【０００４】
本発明は、このような従来の問題点に着目し、かつ、浴室暖房機を備えた給湯装置においては、通常、入浴の前に浴室暖房機を作動させて浴室内を予め暖房しておき、浴室暖房機の停止後に入浴する点に着目したもので、その目的は、この浴室暖房機の作動を有効に利用し、極力、適温キープ運転の終了直後に入浴できることが可能な浴室暖房機付き給湯装置の提供にある。
【０００５】
【課題を解決するための手段】
この目的を達成するため、請求項１に記載の発明によれば、浴室暖房機の作動を制御する暖房制御手段が、浴室暖房機を作動状態から停止状態に切り換えるに伴って、追焚き手段の作動を制御する風呂制御手段が、適温キープ運転を開始するものであるから、浴室暖房機の作動の停止を待って入浴することにより、入浴時に浴槽内の湯が入浴に適した温度に維持されている可能性が高く、従来のような低い湯温での入浴を極力回避して、最適な湯温での入浴を行い得る。
【０００６】
請求項２に記載の発明によれば、暖房制御手段に暖房の作動開始を指示する暖房開始手段を設け、この暖房開始手段により作動開始の指示があると、暖房制御手段が、浴室暖房機を設定時間作動させて停止させるものであるから、浴室暖房機の作動時間を予め設定しておくことにより、浴室内が適温に暖房された後に停止させることができ、したがって、浴室暖房機の作動停止を待って入浴することで、適温暖房下での適温入浴が可能となる。
しかも、暖房の作動停止を指示する暖房停止手段を設け、この暖房停止手段による作動停止の指示があると、例え浴室暖房機が作動中であっても浴室暖房機の作動を停止して適温キープ運転を開始するものであるから、浴室内が適温に暖房される前においても、必要に応じて最適な湯温での入浴を行うことができる。
【０００７】
請求項３に記載の発明によれば、暖房制御手段に制御指令を指示する暖房用リモコンを設け、この暖房用リモコンに暖房開始手段と暖房停止手段とを設けるとともに、適温キープ運転の開始を指示するキープ運転指示手段を設けるものであるから、この暖房用リモコンの操作によって暖房運転の開始や適温キープ運転の開始を指示することができ、例えば、この暖房用リモコンを浴室に隣接する脱衣室などに設置することにより、脱衣前に暖房運転や適温キープ運転の開始を指示することで、入浴に際して適温暖房下で適温入浴が可能となるなど、極めて便利に、かつ、合理的に使用することができる。
【０００８】
請求項４に記載の発明によれば、風呂制御手段が、適温キープ運転の際に、浴槽内の湯水の量が設定量になるように湯水供給手段の作動を制御する適量キープ運転をも実行するものであるから、入浴の際には湯量も適量に維持され、適温適量での入浴が可能となる。
【０００９】
請求項５に記載の発明によれば、給水路からの水を加熱して浴槽に供給する給湯手段を備え、給湯の作動開始を指示する給湯開始手段により給湯開始の指示があると、風呂制御手段が、浴槽内に設定温度の湯水を設定量供給する適温適量湯張り運転を実行するものであるから、上述の適温キープ運転や適温適量キープ運転に加えて、適温適量での湯張り運転も可能となり、実際の使用に際して極めて便利である。
【００１０】
請求項６に記載の発明によれば、風呂制御手段が、湯張り運転の完了後において設定時間経過毎に適温キープ運転を実行するものであるから、浴室暖房機の作動とは無関係に適温キープ運転や適温適量キープ運転が実行されることになり、例え浴室暖房機の作動開始やキープ運転の指示などを忘れて入浴した場合においても、浴槽内の湯はある程度適温や適量に維持されることになる。
【００１１】
請求項７に記載の発明によれば、風呂制御手段が、湯張り運転の完了後において浴室暖房機が作動停止状態にあると、設定時間経過毎に適温キープ運転を実行するものであるから、入浴前の浴室暖房機の作動中においては、適温キープ運転や適温適量キープ運転などを実行せず、不必要なキープ運転の実行を回避して省エネルギ化に寄与し、しかも、浴室暖房機を作動しない場合においても、ある程度適温や適量に維持される。
【００１２】
【発明の実施の形態】
本発明の浴室暖房機付き給湯装置の実施の形態を図面に基づいて説明する。
この浴室暖房機付き給湯装置は、図１に示すように、浴槽１や図外の給湯栓に給湯するための給湯手段としての給湯用動作部Ａと、浴室内を暖房したり乾燥したりするための浴室暖房乾燥機２に給湯するための暖房用動作部Ｂとを備え、かつ、浴槽１内の湯水を追焚きするための追焚き手段としての追焚き用動作部Ｃを備えていて、これら給湯用動作部Ａ、暖房用動作部Ｂ、追焚き用動作部Ｃが、ひとつの熱源機内に収納されている。
【００１３】
前記給湯用動作部Ａは、燃焼室内に配設されたガス燃焼式のバーナ３、このバーナ３により加熱される給湯用熱交換器４、バーナ３に燃焼用空気を供給するファン５などからなり、バーナ３には、点火のためのイグナイタや着火を検出するフレームロッドなどが設けられている。
前記給湯用熱交換器４には、一般家庭用の水道管に接続して加熱用の水を供給する給水路６と、加熱後の湯を供給する給湯路７とが接続され、かつ、給水路６と給湯路７とが、給湯用熱交換器４を迂回する状態でバイパス路８を介して互いに接続されている。このバイパス路８には、給湯路７からの湯の量と給水路６からの水の量との混合比率を調整して、所望の温度の湯を得るためのバイパス弁９が設けられ、図外の電動モータによって作動可能に構成されている。
【００１４】
前記給水路６には、給湯用熱交換器４への入水温度を検出する入水サーミスタ１０と、通水量を検出する水量センサ１１とが設けられ、給湯路７には、加熱後の湯の温度を検出する出湯サーミスタ１２が設けられていて、さらに、バイパス路８との接続箇所よりも下流側の給湯路７には、バイパス弁９の作動によって混合された後の湯の温度を検出する給湯サーミスタ１３が設けられている。
前記給湯用動作部Ａのバーナ３には、一般家庭用の燃料ガスが供給されるように構成され、燃料ガスの供給を断続する電磁式断続弁１４を有する元ガス供給路１５から分岐の給湯用ガス供給路１６が接続され、このガス供給路１６には、燃料ガスの供給量を調節する電磁比例弁１７と、燃料ガスの供給を断続する電磁式断続弁１８とが設けられている。
【００１５】
前記暖房用動作部Ｂも、燃焼室内に配設されたガス燃焼式のバーナ１９、このバーナ１９により加熱される暖房用熱交換器２０、バーナ１９に燃焼用空気を供給するファン２１などからなり、バーナ１９には、元ガス供給路１５から分岐の暖房用ガス供給路２２が接続されて、それに電磁比例弁２３と電磁式断続弁２４とが設けられ、かつ、イグナイタやフレームロッドも設けられている。
前記暖房用熱交換器２０には、暖房用の膨張タンク２５内の水を供給する暖房用給水路２６と、加熱後の湯を供給する暖房用給湯路２７とが接続され、この暖房用給湯路２７が、前記浴室暖房乾燥機２内の熱交換器に接続されるとともに、その熱交換器により熱交換された後の湯水が、暖房用戻り路２８を介して膨張タンク２５内に戻されるように構成されている。
【００１６】
前記バーナ１９の燃焼によって暖房用熱交換器２０で加熱された後の湯は、前記追焚き用動作部Ｃの熱源としても利用され、そのため、前記暖房用給湯路２７と暖房用戻り路２８とは、浴室暖房乾燥機２を迂回する状態で追焚きバイパス路２９を介して互いに接続され、その追焚きバイパス路２９には、浴槽１内の湯水を追焚きするための追焚き用熱交換器３０と、ヒータによる加熱で開弁する熱動弁３１とが設けられている。
前記暖房用給水路２６には、膨張タンク２５内の水を吸引して暖房用熱交換器２０に供給するとともに、加熱後の湯を浴室暖房乾燥機２や追焚き用熱交換器３０に供給するための循環ポンプ３２が設けられ、暖房用給湯路２７には、加熱後の湯の温度を検出する暖房サーミスタ３３が設けられている。
【００１７】
前記追焚き用動作部Ｃは、浴槽１内の湯水を追焚き用熱交換器３０に供給し、この追焚き用熱交換器３０で加熱された後の湯を浴槽１内に戻す追焚き循環路３４や追焚き用熱交換器３０などからなり、前記追焚き循環路３４が、風呂アダプタ３５を介して浴槽１に接続されている。
この追焚き循環路３４は、浴槽１内の湯水を追焚き用熱交換器３０にまで供給する風呂戻り路３６と、加熱後の湯を浴槽１にまで供給する風呂往き路３７とからなり、風呂戻り路３６側には、浴槽１内の湯水を循環されるための風呂循環ポンプ３８が設けられ、かつ、この風呂循環ポンプ３８と浴槽１との間の風呂戻り路３６には、浴槽１側から順に、浴槽１内の湯水の温度を検出する風呂サーミスタ３９、水流スイッチ４０、浴槽１内の湯水の水位を検出する水位センサ４１とが設けられている。
【００１８】
前記風呂循環ポンプ３８と追焚き用熱交換器３０との間の風呂戻り路３６には、前記給湯サーミスタ１３より下流側の給湯路７から分岐された湯張り路４２が接続され、給湯用動作部Ａからの湯を浴槽１内に供給可能に構成され、その湯張り路４２には、上流側から順に、風呂電磁弁４３、逆止弁付き大気開放式のホッパ４４、逆止弁４５とが設けられている。
前記ホッパ４４と逆止弁４５とは、浴槽１内の湯水が湯張り路４２を介して給湯路７側に逆流するのを防止するためのもので、例え逆止弁４５が故障して浴槽１内の湯水が逆流しても、ホッパ４４によって逆流が遮断され、かつ、逆流した湯水がホッパ４４内に貯められるように構成されている。このホッパ４４には、貯められた湯水を浴槽１内に戻すための排水電磁弁４６付きの戻し路４７が接続され、この戻し路４７が水位センサ４１と風呂循環ポンプ３８との間の風呂戻り路３６に接続されるとともに、ホッパ４４内の湯水をオーバーフローさせるための排水路４８も設けられている。
【００１９】
前記給湯用動作部Ａ、暖房用動作部Ｂ、追焚き用動作部Ｃ、ならびに、浴室暖房乾燥器２などの作動は、全てマイクロコンピュータを主要部とする制御部Ｈにより制御されるように構成されている。
この制御部Ｈは、図３に示すように、給湯用動作部Ａ、暖房用動作部Ｂ、および、追焚き用動作部Ｃの作動を制御する風呂制御手段としての熱源機用制御部Ｈ１と、浴室暖房乾燥機２の作動を制御する暖房制御手段としての暖房用制御部Ｈ２とならなり、熱源機用制御部Ｈ１は熱源機内に、暖房用制御部Ｈ２は浴室暖房乾燥機２内にそれぞれ収納されていて、両者は通信制御部４９，５０を介して互いに通信可能に接続されている。
そして、熱源機用制御部Ｈ１側の通信制御部４９には、メインリモコンＲ１と風呂リモコンＲ２とが、暖房用制御部Ｈ２側の通信制御部５０には、暖房用リモコンＲ３がそれぞれ通信可能に接続されている。
【００２０】
前記メインリモコンＲ１は、通常、台所などに設置されるもので、このメインリモコンＲ１には、運転スイッチ５１、一般給湯運転時の給湯温度を設定する温度設定スイッチ５２、浴槽１への給湯開始手段としての湯張りスイッチ５３などが設けられている。
風呂リモコンＲ２は、図２に示すように、浴室Ｄ内の浴槽１の近くに設置されるもので、メインリモコンＲ１と同様に、運転スイッチ５４、湯張りスイッチ５５が設けられ、キープ運転指示手段としてのキープ運転スイッチ５６、湯張り温度やキープ運転時における湯の温度を設定する温度設定スイッチ５７なども設けられている。
暖房用リモコンＲ３は、浴室Ｄに隣接する脱衣室Ｅ内に設置され、暖房開始手段としての暖房スイッチ５８、乾燥スイッチ５９、暖房停止手段としての停止スイッチ６０、キープ運転指示手段としてのキープ運転スイッチ６１などが設けられている。
【００２１】
この浴室暖房機付き給湯装置の作動について説明すると、メインリモコンＲ１の運転スイッチ５１か風呂リモコンＲ２の運転スイッチ５４を入れることで作動可能な状態となり、この状態で図外の給湯栓を開けると、給湯用動作部Ａが作動して一般給湯運転が実行される。
この一般給湯運転においては、給水路６内を設定量以上の水が流通したことを水量センサ１１が検出して、ファン５を回転駆動し、元ガス供給路１５の電磁式断続弁１４と給湯用ガス供給路１６の電磁式断続弁１８とを開弁し、かつ、電磁比例弁１７の開度を調整して、イグナイタによりバーナ３に点火する。このバーナ３の燃焼により、給湯用熱交換器４によって加熱された後の湯は、バイパス弁９によりバイパス路８からの水と混合され、メインリモコンＲ１の温度設定スイッチ５２により設定された温度に調整されて給湯栓から吐出される。
【００２２】
作動可能な状態でメインリモコンＲ１の湯張りスイッチ５３か風呂リモコンＲ２の湯張りスイッチ５５を入れると、風呂電磁弁４３が開弁するとともに、給湯用動作部Ａが作動して浴槽１内への湯張り運転が実行される。
この湯張り運転においても、先の一般給湯運転と同様に、熱交換器４によって加熱された湯が、バイパス路８からの水と混合され、風呂リモコンＲ２の温度設定スイッチ５７により設定された温度に調整されて、湯張り路４２、ならびに、風呂戻り路３６と風呂往き路３７とを介して風呂アダプタ３５から浴槽１内に供給される。浴槽１内に設定量の湯が供給されると、水位センサ４１の検出に基づいて風呂電磁弁４３が閉弁し、両電磁式断続弁１４，１８や電磁比例弁１７も閉弁してバーナ３の燃焼が停止し、一定時間経過後にファン５も停止される。
【００２３】
その後、風呂循環ポンプ３８が駆動して風呂サーミスタ３９が浴槽１内の湯水の温度を検出し、その検出温度が風呂リモコンＲ２の温度設定スイッチ５７による設定温度に達していれば、風呂循環ポンプ３８が停止して、温度設定スイッチ５７により設定した適温と水位センサ４１での適量による湯張りが終了する。
設定温度に達していなければ、追焚き用動作部Ｂが作動して追焚き運転が実行される。この追焚き運転においては、熱動弁３１が開弁し、循環ポンプ３２とファン２１とが回転駆動し、かつ、元ガス供給路１５の電磁式断続弁１４と暖房用ガス供給路２２の電磁式断続弁２４とが開弁するとともに、電磁比例弁２３の開度調整の基にバーナ１９が燃焼される。バーナ１９の燃焼により加熱された後の湯と浴槽１内の湯水とが、追焚き用熱交換器３０で熱交換され、風呂サーミスタ３９による検出温度が設定温度に達した時点で、風呂循環ポンプ３８が停止し、バーナ１９の燃焼も停止して、適温適量湯張りが終了する。
【００２４】
この適温適量湯張りが終了すると、引き続いて自動的に適温適量キープ運転が実行されて、浴槽１内の湯が適温と適量に維持される。
この適温適量キープ運転は、予め設定された時間経過毎に自動的に繰り返され、まず、水位センサ４１によって浴槽１内の湯量が適量に維持されているか否かを検出し、湯量が不足していると、足し湯運転が実行される。この足し湯運転は、上述の湯張り運転と同じ作動により、温度設定スイッチ５７により設定された温度の湯が浴槽１内に供給され、浴槽１内の湯量が適量にキープされる。その後、風呂循環ポンプ３８が駆動して風呂サーミスタ３９が浴槽１内の湯水の温度を検出し、その検出温度が温度設定スイッチ５７による設定温度に達していれば、風呂循環ポンプ３８が停止し、達していなければ、上述の追焚き運転と同じ作動によって追焚きされ、風呂サーミスタ３９による検出温度が設定温度に達した時点で、風呂循環ポンプ３８やバーナ１９の燃焼が停止し、浴槽１内の湯の温度が適温にキープされる。
【００２５】
この適温適量キープ運転は、図４のフローチャートに示すように、予め設定された時間経過毎に自動的に開始して繰り返されるのであるが、暖房用リモコンＲ３の暖房スイッチ５８により後述する暖房運転が実行され、かつ、その暖房運転が自動的に停止されると、設定時間が経過していなくとも開始される。また、暖房運転中であっても、暖房用リモコンＲ３の停止スイッチ６０を入れると、暖房運転が停止するので、この暖房運転の停止に伴って適温適量キープ運転が開始される。
また、暖房運転中であっても、風呂リモコンＲ２のキープ運転スイッチ５６か暖房用リモコンＲ３のキープ運転スイッチ６１を入れると、浴室暖房乾燥機２による暖房運転と並行して適温適量キープ運転が開始される。
なお、このようなキープ運転開始の判断は、キープ運転中でない場合にのみ行われ、キープ運転中の場合には、このような判断を行うことなく、浴槽１内の湯が適温かつ適量になるまでキープ運転を実行する。
【００２６】
この暖房運転においては、暖房用リモコンＲ３の暖房スイッチ５８を入れることで、暖房用動作部Ｂが作動して浴室Ｄ内を暖房する。
この暖房運転では、熱動弁３１が閉弁したままとなり、バーナ１９の燃焼で暖房用熱交換器２０によって加熱された後の湯が、暖房用給湯路２７を介して浴室暖房乾燥機２内の熱交換器にまで送られる。この浴室暖房乾燥機２には、ファンやダンパが内装されていて、そのファンにより浴室Ｄ内の空気が吸引されて浴室暖房乾燥機２の熱交換器で加熱され、加熱後の温風が浴室Ｄ内に排出されて暖房運転が実行され、図外タイマーの作動によって予め設定された時間経過後に、バーナ１９の燃焼が停止され、ファンも停止されて自動的に停止する。
この浴室暖房乾燥機２の作動時間については、タイマーにより自由に設定変更できるように構成され、また、暖房運転中であっても、暖房用リモコンＲ３の停止スイッチ６０を入れることで、暖房運転を停止させることができる。
【００２７】
この暖房運転と同じ作動により、浴室暖房乾燥機２を利用して浴室Ｄ内の洗濯物を乾燥させることもできる。すなわち、暖房用リモコンＲ３の乾燥スイッチ５９を入れると、先の暖房運転と同じ作動によって浴室Ｄ内の温度が上昇する。この乾燥運転においては、ダンパの開度調整によって浴室Ｄ内から吸引した空気の一部を湿気と共に浴室Ｄ外の放出するように構成されているので、浴室Ｄ内に干した洗濯物を短時間のうちに乾燥させることができる。
この乾燥運転の作動時間についても、タイマーによって自由に設定変更でき、また、停止スイッチ６０を入れることで、乾燥運転中であっても、その乾燥運転を停止させることができる。
【００２９】
〔別実施形態〕
先の実施形態においては、給湯用動作部Ａの作動によって、浴槽１内に設定温度の湯を供給して湯張りしたり足し湯する構成のものを示したが、浴槽１内に設定温度以下の低温の湯や水を供給し、その後、追焚き用動作部Ｃを作動させて浴槽１内の湯を設定温度にまで焚き上げる構成のものや、足し湯の際に低温の湯や水を供給して追焚きする構成のものにも適用することができ、このように低温の湯や水を供給するものを湯水供給手段と称する。
さらに、暖房用動作部Ｂや追焚き用動作部Ｃについても種々変更が可能であり、例えば、追焚き用熱交換器３０をバーナによって直接加熱するように構成したり、あるいは、浴室暖房乾燥機２に代えて、暖房運転のみ可能な浴室暖房機を用いて実施することもできる。
【００３０】
その他、制御部Ｈを熱源機側に収納の熱源機用制御部Ｈ１と浴室暖房乾燥機２側に収納の暖房用制御部Ｈ２とから構成し、両者を通信可能に接続したものを示したが、この熱源機用制御部Ｈ１と暖房用制御部Ｈ２とをひとつの制御部Ｈで構成し、その制御部Ｈを熱源機側に収納して実施することもできる。
