Description

【０００１】
【産業上の利用分野】
本発明は、別の保温手段である蓄熱槽を備えた２４時間浴水浄化循環装置に関する。
【０００２】
【従来の技術】
従来より、２４時間風呂なる浴水浄化循環装置においては、特に、湯（浴水）が適宜の温度で常に入浴可能な状態となっていること。且つ湯垢等を除去させた浴水とすること。さらに、その浴水は衛生面からも殺菌されている必要がある。また、浴水浄化循環装置では、一般に、循環した出口等にはジェット噴流等を設け、身体に刺激を与えるように構成されているのが現状である。
【０００３】
【発明が解決しようとする課題】
２４時間浴水浄化循環装置は、２４時間いつでも入浴できる便利さゆえに市場に普及しつつある。その従来の２４時間浴水浄化循環装置は主として電気エネルギーを熱源として使用しており、２４時間保温しているためには２４時間の時間中の内、略連続的に、又は間欠的にエネルギーを供給しなければならなかった。このため、電気代が多くかかる不都合があった。一方、夜間電力などを利用した電気温水器も多く市場に普及されており、この電気代節約型の２４時間浴水浄化循環装置の出現も望まれている。また、蓄熱材として水を用いた場合、蓄熱温度が低く、１００℃を越えての使用ができず、装置が大型化する欠点があった。
【０００４】
【課題を解決するための手段】
本発明は、浴槽内から浴水を循環ポンプにより入力側循環配管を介して流入し循環させて殺菌及び微細なごみ不純物等を濾過して出力側循環配管を通して浴槽に戻すようにした浴水浄化循環装置（Ａ）と、タンク内に蓄熱媒体と、該蓄熱媒体の内部に電力利用のヒーターを設け、前記蓄熱媒体の内部に蓄熱用水タンク部を設け、該蓄熱用水タンク部の下部に連結した入力側蓄熱配管を第１切換手段を介して前記入力側循環配管に連結すると共に、蓄熱用水タンク部の上部に連結した出力側蓄熱配管を前記出力側循環配管に連結して浴水を流入して蓄熱用水タンク部の浴水を高温に保持する蓄熱槽と、浴水の温度を検知するための温度計測手段と、該温度計測手段の検出温度に対応して、前記第１切換手段を動作させて、浴水を前記浴水浄化循環装置（Ａ）のみを循環する状態と、浴水の一部を前記入力側蓄熱配管を介して前記蓄熱用水タンク部の下部から前記蓄熱槽に流入させて前記蓄熱用水タンク部の上部から高温の蓄熱湯を前記出力側蓄熱配管を介して前記出力側循環配管に流出すると共に浴水の一部を前記浴水浄化循環装置（Ａ）を循環させて前記出力側循環配管で合流させて混合して浴槽に流出して浴水の温度を上昇させる状態とに制御するための制御手段とを備えたことにより課題を解決することができた。
さらに本発明は、浴槽内から浴水を循環ポンプにより入力側循環配管を介して流入し循環させて殺菌及び微細なごみ不純物等を濾過して出力側循環配管を通して浴槽に戻すようにした浴水浄化循環装置（Ａ）と、タンク内に蓄熱媒体と、該蓄熱媒体の内部に電力利用のヒーターを設け、前記蓄熱媒体の内部に蓄熱用水タンク部を設け、該蓄熱用水タンク部の下部に連結した入力側蓄熱配管を第１切換手段を介して前記入力側循環配管に連結すると共に、蓄熱用水タンク部の上部に連結した出力側蓄熱配管を前記出力側循環配管に連結して浴水を流入して蓄熱用水タンク部の浴水を高温に保持する蓄熱槽と、浴水の温度を検知するための温度計測手段と、該温度計測手段の検出温度に対応して、前記第１切換手段を動作させて、浴水を前記浴水浄化循環装置（Ａ）のみを循環する状態と、浴水の一部を前記入力側蓄熱配管を介して前記蓄熱用水タンク部の下部から前記蓄熱槽に流入させて前記蓄熱用水タンク部の上部から高温の蓄熱湯を前記出力側蓄熱配管を介して前記出力側循環配管に流出すると共に浴水の一部を前記浴水浄化循環装置（Ａ）を循環させて前記出力側循環配管で合流させて混合して浴槽に流出して浴水の温度を上昇させる状態と、浴水を前記入力側蓄熱配管を介して前記蓄熱用水タンク部の下部から前記蓄熱槽に流入させて前記蓄熱用水タンク部の上部から高温の蓄熱湯を前記出力側蓄熱配管を介して前記出力側循環配管に流出して該出力側循環配管から高温の蓄熱湯のみを浴槽に流出させて浴槽の浴水を急速加熱する状態とに制御するための制御手段とを備えたことにより課題を解決することができた。
さらに本発明は、前記制御手段は前記温度計測手段が所定の設定温度を越えた浴水の温度変化の検知に応答して外部水源からの水を浴槽に供給する配管路に設けた給水弁を動作させて浴水温度を低下させるように制御することにより課題を解決することができた。
また本発明は、前記浴水浄化循環装置（Ａ）にシーズヒータ等の別の加熱手段を設けるようにしたことにより課題を解決することができた。
さらに本発明は、浴槽内から浴水を循環ポンプにより入力側循環配管を介して流入し循環させて殺菌及び微細なごみ不純物等を濾過して出力側循環配管を通して浴槽に戻すようにした浴水浄化循環装置（Ａ）と、タンク内に蓄熱媒体と、該蓄熱媒体の内部に電力利用のヒーターを設け、前記蓄熱媒体の内部に蓄熱用水タンク部を設け、該蓄熱用水タンク部の上部に連結した出力側蓄熱配管を前記出力側循環配管に連結して蓄熱用水タンク部の水を高温に保持する蓄熱槽と、浴水の温度を検知するための温度計測手段と、該温度計測手段の検出温度に対応して、浴水を前記浴水浄化循環装置（Ａ）のみを循環する状態と、前記蓄熱槽のタンクの上部から高温の湯を前記出力側蓄熱配管を介して前記出力側循環配管に流出して前記浴水浄化循環装置（Ａ）を循環させた浴水に前記出力側循環配管で合流させて混合して浴槽に流出して浴水の温度を上昇させる状態とに制御するための制御手段とを備えたことにより課題を解決することができた。
さらに本発明は、浴槽内から浴水を循環ポンプにより入力側循環配管を介して流入し循環させて殺菌及び微細なごみ不純物等を濾過して出力側循環配管を通して浴槽に戻すようにした浴水浄化循環装置（Ａ）と、タンク内に蓄熱媒体と、該蓄熱媒体の内部に電力利用のヒーターを設け、前記蓄熱媒体の内部に蓄熱用水タンク部を設け、蓄熱用水タンク部の上部に連結した出力側蓄熱配管を前記出力側循環配管に連結して蓄熱用水タンク部の水を高温に保持する蓄熱槽と、浴水の温度を検知するための温度計測手段と、該温度計測手段の検出温度に対応して、浴水が前記浴水浄化循環装置（Ａ）を循環する状態と、前記蓄熱槽のタンクの上部から高温の湯を前記出力側蓄熱配管を介して前記出力側循環配管に流出して前記浴水浄化循環装置（Ａ）を循環させた浴水に前記出力側循環配管で合流させて混合して浴槽に流出して浴水の温度を上昇させる状態と、前記タンクの上部から高温の湯を前記出力側蓄熱配管を介して前記出力側循環配管に流出して該出力側循環配管から高温の湯のみを浴槽に流出させて浴水を急速加熱する状態とに制御するための制御手段とを備えたことにより課題を解決することができた。
また本発明は、前記浴水浄化循環装置（Ａ）にシーズヒータ等の別の加熱手段を設けるようにしたことにより課題を解決することができた。
【０００５】
そこで発明者は、前記課題を解決すべく、鋭意，研究を重ねた結果、その発明を、浴槽内から浴水を循環ポンプにより入力側循環配管を介して流入し循環させて殺菌及び微細なごみ不純物等を濾過して出力側循環配管を通して浴槽に戻すようにした浴水浄化循環装置（Ａ）と、タンク内に蓄熱媒体と、該蓄熱媒体の内部に電力利用のヒーターを設け、前記蓄熱媒体の内部に蓄熱用水タンク部を設け、該蓄熱用水タンク部の下部に連結した入力側蓄熱配管を循環路切換手段を介して前記入力側循環配管に連結すると共に、該入力側蓄熱配管から蓄熱用水タンク部に流入し貯溜される浴水を前記蓄熱媒体により加熱し且つ高温に保持すると共に、蓄熱用水タンク部の上部に連結した出力側蓄熱配管を前記出力側循環配管に連結する蓄熱槽と、浴水の温度を検知するための温度計測手段と、該温度計測手段の検出温度に対応して、前記循環路切換手段を動作させて、浴水を前記浴水浄化循環装置のみを循環する状態と、浴水の一部を前記入力側蓄熱配管を介して前記蓄熱用水タンク部の下部から前記蓄熱槽に流入させて前記蓄熱用水タンク部の上部から前記蓄熱媒体により加熱されて貯溜されている高温の蓄熱湯を前記出力側蓄熱配管を介して前記出力側循環配管に流出すると共に前記浴水浄化循環装置（Ａ）からの浴水に合流させて混合して浴槽に流出して浴水の温度を上昇させる状態とに制御するための制御手段とを備えたことを特徴とする２４時間浴水浄化循環装置としたことにより、蓄熱槽として夜間電力使用態様にすることで、飛躍的に、電力エネルギーコストを軽減することができ、蓄熱材の利点と水の利点とを折衷させつつ、前記課題を解決したものである。
【０００６】
【実施例】
以下、本発明の実施例について図１乃至図１５に基づいて説明すると、まず、第１実施例について、図１乃至図５について述べる。浴水浄化循環装置Ａは、図１に示すように、浴水を循環させるための循環ポンプ１と、浴水を殺菌する殺菌装置２と、微細なごみ及び汚れなる不純物を浴水から濾過する濾過装置３とから構成されている。その循環ポンプ１，殺菌装置２，濾過装置３は、相互に直列状に連結管４を介して浴水が連通するように構成されている。実施例では、循環ポンプ１，殺菌装置２，濾過装置３の順であるが、この順序には必ずしも限定されない。
【０００７】
前記殺菌装置２としては、オゾン発生器，オゾン水注入手段，紫外線殺菌手段等が存在している。そのオゾン発生器は、オゾナイザー部と、オゾンを混入するオゾン混入部とから構成されている。また、オゾン水注入手段は、オゾン水発生部と、これから殺菌管路にオゾン水を注入し溜めるタンク部とから構成されている。紫外線殺菌手段は、ケース内部に紫外線ランプが設けられ、該紫外線ランプの照射を受けながら浴水が通過するように構成されている。
【０００８】
その濾過装置３に使用するフィルタの種類としては、精密フィルタ又は普通フィルタであり、活性石，活性炭を充填したものとして吸着剤濾材フィルタ材として使用したり、或いは、織布又は不織布からなりフィルタ素材から構成するものもある。何れにしても、不純物なる微細なるごみ及び汚れを除去する。
【０００９】
上記のように浴水浄化循環装置Ａの入力側には、浴槽１０内から浴水を流入する入力側循環配管５が連結され、且つ浴水浄化循環装置Ａの出力側には、浴槽１０内に浴水を流出させる出力側循環配管６が設けられている。その入力側循環配管５の吸込み側には、プレフィルタ７が設けられ、その出力側循環配管６の排出口にはジェット噴流が出るように噴出部８が必要に応じて設けられている。
【００１０】
蓄熱槽３０は、タンク３０ａの内部に、蓄熱媒体３３と、蓄熱用水タンク部３０ｂが設けられている。具体的には、そのタンク３０ａの内部に、その内壁を覆うようにして蓄熱媒体３３が設けられ、該蓄熱媒体３３の内部が、蓄熱用水タンク部３０ｂとして構成されている。その蓄熱媒体３３の内部に電力利用のヒーター３０ｃが埋設され加熱可能に構成されている。その蓄熱媒体３３の加熱にて蓄熱用水タンク部３０ｂ内の水が昇温可能に構成されている。
【００１１】
前記蓄熱媒体３３としては、ポリエチレングリコール、酢酸ソーダ，高密度ポリエチレン、パラフィン等の有機材が存在している。具体的には、酢酸ソーダとしては、融解温度５８℃、潜熱６０ｃａｌ／ｇである。また、高密度ポリエチレンとしては、融解温度１２０℃〜１５０℃、潜熱約４３〜約５７ｃａｌ／ｇである。さらに、ポリエチレングリコールは、分子量が５０００〜７０００、融解温度５８℃〜６２℃、潜熱４６ｃａｌ／ｇである。
【００１２】
前記蓄熱媒体３３を電源にて加熱可能にする蓄熱槽３０について、深夜電力を利用すると、電力使用料が比較的安価にできる。その深夜電力には、深夜電力甲，乙（午後１１時から翌朝７時の時間帯に温水のために使う電力）、第２深夜電力（午前１時から午前６時の時間帯に温水のために使う電力）等が存在し、その割引料金は、各電力会社によってそれぞれ異なっている。
【００１３】
前記蓄熱槽３０について、深夜電力を利用すると、電力使用料が比較的安価にできる。その深夜電力には、深夜電力甲，乙（午後１１時から翌朝７時の時間帯に温水のために使う電力）、第２深夜電力（午前１時から午前６時の時間帯に温水のために使う電力）等が存在し、その割引料金は、各電力会社によってそれぞれ異なっている。
【００１４】
１１は入力側蓄熱配管であって、前記蓄熱槽３０の入力側に連結され、出力側蓄熱配管１２の一端は、蓄熱槽３０の出力側に連結されている。その入力側蓄熱配管１１の他端（流入側）は、前記浴水浄化循環装置Ａの循環ポンプ１の後位の連結管４に、循環路切換手段１３を介して連結されている。また、出力側蓄熱配管１２の他端（流出側）は、前記出力側循環配管６の中間に第１切換手段１４を介して連通されている。
【００１５】
前記浴水浄化循環装置Ａとしての入力側循環配管５の途中には、中央演算処理装置２１に接続された温度計測手段２２が設けられ、その浴水浄化循環装置Ａの内の浴水の温度に応じて、弁制御手段２３の動作により、浴水等の流路が適宜切り換えられ、所定の温度制御可能に構成されている。また、設定温度記憶手段２４には予め所望温度が記憶されている。この設定温度は適宜変更可能にＲＡＭとして構成されている。また、計測した温度と設定温度とを比較する温度比較手段２５も中央演算処理装置２１に設けられている。また、別の水源からの給水弁２６も、浴水の温度を下げるために、弁制御手段２３にて制御可能に設けられている。
【００１６】
適宜の所望の設定温度範囲内（例えば、約４０乃至４２℃）では、循環路切換手段１３の流路は、入力側蓄熱配管１１に流出せず、浴水浄化循環装置Ａ内のみを通過するように構成され、且つ第１切換手段１４の流路も浴水浄化循環装置Ａ内のみが通過するように構成されている〔図３（Ａ）参照〕。また、僅かに温度低下した場合（約数度以内）には、循環路切換手段１３の流路は、入力側蓄熱配管１１側から蓄熱槽３０を通過し、且つ浴水浄化循環装置Ａ内をも通過するように構成され、且つ第１切換手段１４を介して蓄熱槽３０内の蓄熱湯も、浴水浄化循環装置Ａ内の浴水も前記出力側循環配管６を通過するように構成されている〔図３（Ｂ）参照〕。さらに、大きく温度低下した場合（約数度以上）には、循環路切換手段１３の流路としての浴水浄化循環装置Ａ内の通過を遮断し、入力側蓄熱配管１１側から蓄熱槽３０のみを通過するように構成され、且つ第１切換手段１４の流路も浴水浄化循環装置Ａ内の浴水通過を遮断し、蓄熱槽３０内のみの蓄熱湯を前記出力側循環配管６から通過するように構成されている〔図３（Ｃ）参照〕。
【００１７】
次に、図５に示すフローチャートにより説明する。まず、本発明の装置の運転を開始する。すると、温度計測手段２２にて計測して設定温度範囲内か否かを判断し（Ｓ１参照）、設定温度範囲内の場合には、弁制御手段２３にて弁制御され、循環路切換手段１３の流路は、入力側蓄熱配管１１に流出せず、浴水浄化循環装置Ａ内のみを通過するように構成され、且つ第１切換手段１４の流路も浴水浄化循環装置Ａ内のみが通過するように構成されている〔Ｓ２及び図３（Ａ）参照〕。即ち、浴水浄化循環装置Ａ内の循環ポンプ１の始動にて、浴槽１０，入力側循環配管５，浴水浄化循環装置Ａ，出力側循環配管６とを浴水が循環し殺菌等を行なう。このような循環状態で、さらにＳ１のステップの手前に戻る。また、温度計測手段２２にて計測して、設定温度よりも低いか否かを判断し（Ｓ３参照）、設定温度範囲よりも高くなっている場合には、弁制御手段２３にて弁制御され、給水弁２６が開となって浴水温度を低下させる（Ｓ４参照）。
【００１８】
これで低下している状態で、さらにＳ１のステップの手前に戻る。また、設定温度範囲よりも低くなっている場合には、さらにその測定温度が少し低いか否かを判断し（Ｓ５参照）、少し低い場合には、弁制御手段２３にて弁制御され、浴水浄化循環装置Ａ間及び蓄熱槽３０間を浴水及び蓄熱湯が循環して浴水温度を上昇させる（Ｓ６参照）。即ち、第１切換手段１４が切り換えられ、蓄熱槽３０内の蓄熱湯が、浴水浄化循環装置Ａ内の浴水も前記出力側循環配管６を通過するようになる〔図３（Ｂ）参照〕。このようにして蓄熱湯による浴水温度を上昇させる。その浴水が昇温している間にもＳ１の手前に戻り、繰り返す。このようにして所望の設定温度になった場合には、前述と同様となる。また、大きく温度低下した場合（約数度以上）には（Ｓ５のＮＯの場合）、弁制御手段２３にて弁制御され、蓄熱槽３０間を浴水及び蓄熱湯が循環して浴水温度を上昇させる（Ｓ７参照）。即ち、第１切換手段１４の流路が切り換わり、浴水浄化循環装置Ａ内の浴水通過を遮断し、蓄熱槽３０内のみの蓄熱湯を前記出力側循環配管６から通過し、浴水の温度を上昇させる〔図３（Ｃ）参照〕。このような状態で、さらにＳ１のステップの手前に戻り、Ｓ１からのステップを繰り返し、常時、浴水の設定温度を保持するように構成されている。
【００１９】
第１実施例の変形例としては、図３（Ａ）の場合と、図３（Ｂ）の場合にのみ切り換えるようにすることもある。具体的には、浴水循環において、入力側蓄熱配管１１に流出せず、浴水浄化循環装置Ａ内のみを通過するようになる場合〔図３（Ａ）参照〕と、蓄熱槽３０内の蓄熱湯と浴水浄化循環装置Ａ内の浴水とが混合されつつ前記浴槽１０に流出する場合〔図３（Ｂ）参照〕とで構成されることもある。さらに、第１実施例の変形例としては、図３（Ａ）の場合と、図３（Ｃ）の場合にのみ切り換えるようにすることもある。具体的には、浴水循環において、入力側蓄熱配管１１に流出せず、浴水浄化循環装置Ａ内のみを通過するようになる場合〔図３（Ａ）参照〕と、蓄熱湯のみが前記浴槽１０に流出する場合〔図３（Ｃ）参照〕とで構成されることもある。
【００２０】
また、本発明の第２実施例では、図６及び図７に示すように、第１実施例の第１切換手段１４に替えて、第２切換手段１５を使用した場合である。この場合には、該第２切換手段１５箇所から急速昇温配管１６が設けられている。この場合には、浴槽１０内の温度を急激に上昇させることができる。他の構成は、第１実施例と同一である。その作用について説明すると、設定温度範囲内の場合には、弁制御手段２３にて弁制御され、循環路切換手段１３の流路は、入力側蓄熱配管１１に流出せず、浴水浄化循環装置Ａ内のみを通過するように構成され〔図７（Ａ）参照〕、設定温度範囲よりも高くなっている場合には、弁制御手段２３にて弁制御され、給水弁２６が開となって浴水温度を低下させるし、また、設定温度範囲よりもすこし低くなっている場合には、弁制御手段２３にて弁制御され、浴水浄化循環装置Ａ間及び蓄熱槽３０間を浴水及び蓄熱湯が循環して浴水温度を上昇させる〔図７（Ｂ）及び（Ｃ）参照〕、特に、図７（Ｂ）の場合は、蓄熱湯と浴水とが独立して流出する場合で、図７（Ｃ）の場合は、蓄熱湯と浴水とが混合されて適宜の温度で流出する場合である。また、大きく温度低下した場合（約数度以上）には、蓄熱槽３０間を浴水及び蓄熱湯が循環して浴水温度を上昇させる〔図７（Ｄ）参照〕。フローチャートは、第１実施例の場合と同様である。
【００２１】
また、第３実施例では、図８及び図９に示すように、第１実施例の第１切換手段１４を削除し、出力側循環配管６と、出力側蓄熱配管１２とをそれぞれ独立させて設け、それぞれの端を前記浴槽１０に流出可能に設けられている。浴水が温度低下した場合にこれを温度計測手段２２にて計測して蓄熱槽３０側に循環された蓄熱湯が自動的に流出するようにして浴水を所望温度に制御するように構成されている。この場合は、浴槽１０側に流入されるものは、浴水が循環されて蓄熱槽３０を介した温度の高い蓄熱湯であり、早期に昇温できる。また、設定温度範囲内では、浴水浄化循環装置Ａ内のみを通過するように構成され〔図９（Ａ）参照〕、少し温度が低い場合には、浴水浄化循環装置Ａ間及び蓄熱槽３０間を浴水及び蓄熱湯が循環して浴水温度を上昇させる〔図９（Ｂ）参照〕。他の構成は、第１実施例と同一であり、その説明を省略する。
【００２２】
次に、第４実施例は、図１０に示すように、第１実施例（図１参照）の循環路切換手段１３及び入力側蓄熱配管１１を削除したものであり、他の構成は、第１実施例と同一である。この第４実施例では、特に、浴水の温度が低下した場合には、蓄熱槽３０内の蓄熱湯のみが使用され、浴槽１０内には、浴水は増加はするが、第１実施例と比較して構成は簡単にできる。この場合には、第１切換手段１４のみが制御され、その作用は第１実施例と同様である。
【００２３】
次に、第５実施例は、図１１に示すように、第２実施例（図６及び図７参照）の循環路切換手段１３及び入力側蓄熱配管１１を削除したものであり、他の構成は、第２実施例と同一である。この第５実施例では、特に、浴水の温度が低下した場合には、蓄熱槽３０内の蓄熱湯のみが使用され、浴槽１０内には、浴水は増加はするが、第２実施例と比較して構成は簡単にできる。第５実施例の作用も第２実施例と同様である。
【００２４】
次に、第６実施例は、図１２に示すように、第３実施例（図８及び図９参照）の循環路切換手段１３及び入力側蓄熱配管１１を削除したものであり、他の構成は、第３実施例と同一である。この第６実施例では、特に、浴水の温度が低下した場合には、蓄熱槽３０内の蓄熱湯のみが使用され、浴槽１０内には、浴水は増加はするが、第３実施例と比較して構成は簡単にできる。第６実施例の作用も第３実施例と同様である。
【００２５】
また、第７実施例では、図１３に示すように、前記浴水浄化循環装置Ａと蓄熱槽３０とを直列に構成した場合であり、この場合は、常に、浴水と蓄熱湯とが混合しつつ循環しており、この場合は、特に、蓄熱槽３０内の温度を、浴水としての所望温度に制御する必要があり、そのようにして温度制御し、所望温度以下となった場合は、循環を停止して蓄熱槽３０内の蓄熱湯を昇温させる必要がある。
【００２６】
前記第１乃至第７実施例において、寒冷地等では、前記浴水浄化循環装置Ａの構成部材として、図１４に示すように、シーズヒーター等の加熱手段１８を設けることもある。さらに、前記第１乃至第７実施例において、図１５に示すように、シャワー３５ａが可能な給湯設備部３５を、前記蓄熱槽３０から使用可能とすることもある。そのシャワー３５ａの蓄熱湯と、水道等の水源からの水とで適宜な温度として使用する。図面では、浴水浄化循環装置Ａに加熱手段１８を設けたものであるが、第１乃至第７実施例に適用されるものであり、また、図１５では、第１実施例において、給湯設備部３５を設けているが、他の第２乃至第７実施例にも適用されるものである。
【００２７】
【発明の効果】
請求項１の発明においては、水を電源による蓄熱媒体３３にて加熱させる蓄熱槽３０を利用するため、該蓄熱槽３０の加熱に、例えば夜間電力を利用すれば、電力コストの軽減ができ、より安価に２４時間浴水浄化循環装置を提供できるし、さらに、蓄熱槽３０が並列に配置されているため、加熱不要なときも循環（浄化）を止める必要がない等の利点がある。
【００２８】
その蓄熱槽３０では、深夜電力等の格安の電力を使用し、これを蓄熱槽３０内に蓄熱しておき、これを浴水の加熱用とすることで、従来のような加熱手段としてのヒーターも不要となり、電力節減が可能である。また、請求項１の発明では、温度が下がったときに、浴槽１０側に流入されるものが温度の高い蓄熱湯を直接に流入させることができる。さらに、蓄熱媒体３３は蓄熱材のため、水なる蓄熱媒体とは異なり、潜熱も大きくなり、小型化が可能である。その蓄熱媒体３３を電源にて加熱可能にする部分は水箇所であり、引火性が無く安全率を高くできるし、腐食性が低い等の利点がある。
【００２９】
次に、請求項２の発明では、特に、温度が下がったときに、浴槽１０側に流入されるものが浴水と蓄熱湯との混合されたものであり、略適温のものを得ることができる。また、請求項３の発明では、設定温度範囲よりも高くなっている場合には、弁制御手段にて弁制御され、外部水源からの水の給水弁の動作にて浴水温度を低下させることができる。
【００３０】
次に、請求項４の発明では、請求項１において、前記出力側蓄熱配管１２の取付構成では、その他端は前記出力側循環配管６の途中に、浴水浄化循環装置Ａ側からの浴水のみを、又は前記蓄熱用水タンク部３０ｂの蓄熱湯をそれぞれ流通させるように切り換える第１切換手段１４を介して連通させてなる２４時間浴水浄化循環装置としたことにより、特に、温度が下がったときに、浴槽１０側に流入されるものが蓄熱湯のみであり、急速に略適温のものを得ることができる。
【００３１】
請求項４の発明及び請求項５の発明においても、請求項１又は２の発明と同等の効果を奏するものである。

The late-night power includes midnight power A, B (electric power used for hot water from 11:00 pm to 7:00 am the next day), and second midnight power (for hot water from 1 am to 6:00 am) Etc.), and the discounted charges vary depending on each electric power company.
[0014]
Reference numeral 11 denotes an input side heat storage pipe, which is connected to the input side of the heat storage tank 30, and one end of the output side heat storage pipe 12 is connected to the output side of the heat storage tank 30. The other end (inflow side) of the input side heat storage pipe 11 is connected to the connection pipe 4 at the rear of the circulation pump 1 of the bath water purification / circulation apparatus A through a circulation path switching means 13. Further, the other end (outflow side) of the output side heat storage pipe 12 is communicated with the middle of the output side circulation pipe 6 via the first switching means 14.
[0015]
A temperature measuring means 22 connected to a central processing unit 21 is provided in the middle of the input side circulation pipe 5 as the bath water purification and circulation device A, and the temperature of the bath water in the bath water purification and circulation device A is provided. Accordingly, the flow path of the bath water or the like is appropriately switched by the operation of the valve control means 23 so that a predetermined temperature can be controlled.

A water supply valve 26 from another water source is also provided so as to be controllable by the valve control means 23 in order to lower the temperature of the bath water.
[0016]
Within an appropriate desired set temperature range (for example, about 40 to 42 ° C.), the flow path of the circulation path switching means 13 does not flow out to the input side heat storage pipe 11 and passes only through the bath water purification and circulation apparatus A. Further, the flow path of the first switching means 14 is also configured to pass only through the bath water purification and circulation device A [see FIG. 3 (A)]. Further, when the temperature is slightly lowered (within about several degrees), the flow path of the circulation path switching means 13 passes through the heat storage tank 30 from the input side heat storage pipe 11 side and passes through the bath water purification and circulation apparatus A. And the hot water stored in the heat storage tank 30 and the bath water in the bath water purifying and circulating apparatus A are also configured to pass through the output side circulation pipe 6 via the first switching means 14.

Further, when the temperature is greatly decreased (about several degrees or more), the passage in the bath water purification / circulation device A as the flow path of the circulation path switching means 13 is blocked, and only the heat storage tank 30 from the input side heat storage pipe 11 side is blocked. And the flow path of the first switching means 14 also blocks the passage of the bath water in the bath water purifying and circulating apparatus A, and passes the hot water stored only in the heat storage tank 30 from the output side circulation pipe 6. [See FIG. 3C].
[0017]
Next, a description will be given with reference to the flowchart shown in FIG. First, the operation of the apparatus of the present invention is started. Then, it is measured by the temperature measuring means 22 to determine whether or not it is within the set temperature range (see S1). If it is within the set temperature range, the valve control means 23 controls the valve and the circulation path switching means 13 The flow path of the first switching means 14 does not flow out to the input side heat storage pipe 11 and passes only through the bath water purification / circulation apparatus A, and the flow path of the first switching means 14 is only within the bath water purification / circulation apparatus A. It is configured to pass (see S2 and FIG. 3A). That is, when the circulation pump 1 in the bath water purification / circulation device A is started, the bath water circulates through the bathtub 10, the input side circulation piping 5, the bath water purification / circulation device A, and the output side circulation piping 6 to perform sterilization and the like. . In such a circulating state, the process returns to the position before step S1. Further, the temperature is measured by the temperature measuring means 22 to determine whether the temperature is lower than the set temperature (see S3). When the temperature is higher than the set temperature range, the valve control means 23 controls the valve. Then, the water supply valve 26 is opened to lower the bath water temperature (see S4).
[0018]
With this lowered, the process returns to the position before step S1. If the temperature is lower than the set temperature range, it is further determined whether or not the measured temperature is a little lower (see S5). If the measured temperature is a little lower, the valve control means 23 controls the valve, Bath water and hot water are circulated between the water purification circulation devices A and between the heat storage tanks 30 to raise the bath water temperature (see S6). That is, the first switching means 14 is switched, and the hot water stored in the heat storage tank 30 passes through the output-side circulation pipe 6 as well as the bath water in the bath water purification / circulation device A (see FIG. 3B). ]. In this way, the bath water temperature by the hot water is raised. While the temperature of the bath water is rising, the process returns to S1 and repeats. When the desired set temperature is reached in this way, the same as described above. In addition, when the temperature is greatly decreased (about several degrees or more) (in the case of NO in S5), the valve control means 23 controls the valve, and the bath water and the hot water are circulated between the heat storage tanks 30. Is raised (see S7). That is, the flow path of the 1st switching means 14 switches, the bath water passage in the bath water purification circulation apparatus A is interrupted, the hot water only in the heat storage tank 30 passes from the said output side circulation piping 6, and bath water (See FIG. 3C). In such a state, it is configured to return to the position before the step S1, repeat the steps from S1, and always maintain the set temperature of the bath water.
[0019]
As a modified example of the first embodiment, switching may be performed only in the case of FIG. 3A and the case of FIG. Specifically, in the bath water circulation, when the heat does not flow out to the input side heat storage pipe 11 and only passes through the bath water purification / circulation device A (see FIG. 3A), the heat storage in the heat storage tank 30 is performed. The hot water and the bath water in the bath water purifying and circulating apparatus A may be mixed and flow out into the bathtub 10 (see FIG. 3B). Further, as a modification of the first embodiment, there is a case where switching is performed only in the case of FIG. 3A and the case of FIG. Specifically, in the bath water circulation, when it does not flow out to the input side heat storage pipe 11 and only passes through the bath water purification / circulation device A (see FIG. 3A), only the hot water is stored in the bathtub 10. In some cases (see FIG. 3C).
[0020]

In this case, a rapid temperature raising pipe 16 is provided from the second switching means 15 locations. In this case, the temperature in the bathtub 10 can be rapidly increased. Other configurations are the same as those of the first embodiment. The operation will be described. When the temperature is within the set temperature range, valve control is performed by the valve control means 23, and the flow path of the circulation path switching means 13 does not flow out to the input side heat storage pipe 11, but the bath water purification and circulation device. If the temperature is higher than the set temperature range, the valve control means 23 controls the valve and the water supply valve 26 is opened. When the bath water temperature is lowered or slightly lower than the set temperature range, the valve control means 23 controls the bath water between the bath water purifying and circulating apparatus A and between the heat storage tanks 30 and The stored hot water circulates and raises the bath water temperature (see FIGS. 7B and 7C). In particular, in the case of FIG. 7B, the stored hot water and the bath water flow out independently. In the case of FIG. 7C, the hot water and the bath water are mixed and flow out at an appropriate temperature. Further, when the temperature is greatly reduced (about several degrees or more), the bath water and the hot water are circulated between the heat storage tanks 30 to raise the bath water temperature (see FIG. 7D). The flowchart is the same as that in the first embodiment.
[0021]
Moreover, in 3rd Example, as shown in FIG.8 and FIG.9, the 1st switching means 14 of 1st Example is deleted, and the output side circulation piping 6 and the output side heat storage piping 12 are made independent, respectively. Provided, and each end is provided in the bathtub 10 so as to be able to flow out. When the temperature of the bath water drops, the temperature is measured by the temperature measuring means 22, and the hot water circulated to the heat storage tank 30 side automatically flows out to control the bath water to a desired temperature. ing. In this case, what flows into the bathtub 10 side is hot water having a high temperature through the heat storage tank 30 as the bath water is circulated, and the temperature can be raised quickly. Further, it is configured to pass through only the bath water purification / circulation device A within the set temperature range (see FIG. 9A), and when the temperature is slightly low, between the bath water purification / circulation device A and the heat storage tank. Bath water and hot water are circulated between 30 to raise the bath water temperature (see FIG. 9B). Other configurations are the same as those of the first embodiment, and the description thereof is omitted.
[0022]
Next, as shown in FIG. 10, in the fourth embodiment, the circuit switching means 13 and the input side heat storage pipe 11 of the first embodiment (see FIG. 1) are deleted. The same as one embodiment. In the fourth embodiment, in particular, when the temperature of the bath water decreases, only the hot water stored in the heat storage tank 30 is used, and the bath water increases in the bathtub 10, but In comparison, the configuration can be simplified. In this case, only the first switching means 14 is controlled, and the operation is the same as in the first embodiment.
[0023]
Next, as shown in FIG. 11, the fifth embodiment is obtained by deleting the circulation path switching means 13 and the input side heat storage pipe 11 of the second embodiment (see FIGS. 6 and 7). Is the same as in the second embodiment. In the fifth embodiment, in particular, when the temperature of the bath water is lowered, only the hot water stored in the heat storage tank 30 is used, and the bath water increases in the bathtub 10, but the second embodiment and In comparison, the configuration can be simplified. The operation of the fifth embodiment is the same as that of the second embodiment.
[0024]

[0025]
Further, in the seventh embodiment, as shown in FIG. 13, the bath water purification / circulation device A and the heat storage tank 30 are configured in series. In this case, the bath water and the hot water are always mixed. However, in this case, in particular, it is necessary to control the temperature in the heat storage tank 30 to a desired temperature as bath water. It is necessary to stop the circulation and raise the temperature of the hot water in the heat storage tank 30.
[0026]
