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、蓄熱材として水以外のものを利用した場合、人体への安全性の確保、コスト、寿命などの点で問題があった。
【０００４】
【課題を解決するための手段】
本発明は、浴槽（１０）内から浴水を循環ポンプ（１）により入力側循環配管（５）を介して流入し連結管（４）を循環させて該連結管（４）に連結された殺菌装置（２）と濾過装置（３）により殺菌及び微細なごみ不純物等を濾過して前記連結管（４）に連結する出力側循環配管（６）を通して浴槽（１０）に戻すようにした浴水浄化循環装置(A)と、前記連結管（４）に連結するタンク（３０ａ）内に電力利用のヒーター（３０ｂ）を設け、前記タンク（３０ａ）は下部に一端を連結した入力側蓄熱配管（１１）の他端を前記連結管（４）に設けた循環路切換手段（１３）を介して連結すると共に、前記タンク（３０ａ）の上部に一端を連結した出力側蓄熱配管（１２）を前記連結管（４）に設けられた第1切換手段（１４）に連結して、入力側蓄熱配管（１１）からの浴水を流入してタンク（３０ａ）内の浴水を高温に保持する蓄熱槽（３０）と、浴水の温度を検知するための温度計測手段（２２）と、前記第1切換手段（１４）に前記出力側循環配管を連結して、前記温度計測手段（２２）の検出温度に対応して、前記循環路切換手段（１３）を動作させて、浴水を前記浴水浄化循環装置(A)を循環する状態と、前記循環路切換手段（１３）を動作させて、浴水の一部を前記入力側蓄熱配管（１１）を通して前記タンク（３０ａ）の下部から前記蓄熱槽（３０）に流入させて前記タンク（３０ａ）の上部から高温の浴水を前記出力側蓄熱配管（１２）から前記第1切換手段（１４）を経由して流出すると共に前記浴水浄化循環装置(A)を循環させた浴水の一部を前記第1切換手段（１４）で合流させて混合して前記出力側循環配管（６）から浴槽（１０）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することで、課題を解決することができた。
また、本発明は、浴槽（１０）内から浴水を循環ポンプ（１）により入力側循環配管（５）を介して流入し連結管（４）を循環させて該連結管（４）に連結された殺菌装置（２）と濾過装置（３）により殺菌及び微細なごみ不純物等を濾過して前記連結管（４）に連結する出力側循環配管（６）を通して浴槽（１０）に戻すようにした浴水浄化循環装置(A)と、前記連結管（４）に連結するタンク（３０ａ）内に電力利用のヒーター（３０ｂ）を設け、前記タンク（３０ａ）は下部に一端を連結した入力側蓄熱配管（１１）の他端を前記連結管（４）に設けた循環路切換手段（１３）を介して連結すると共に、前記タンク（３０ａ）の上部に一端を連結した出力側蓄熱配管（１２）を前記連結管（４）に設けられた第1切換手段（１４）に連結して、入力側蓄熱配管（１１）からの浴水を流入してタンク（３０ａ）内の浴水を高温に保持する蓄熱槽（３０）と、浴水の温度を検知するための温度計測手段（２２）と、前記第1切換手段（１４）に前記出力側循環配管を連結して、前記温度計測手段（２２）の検出温度に対応して、前記循環路切換手段（１３）を動作させて、浴水を前記浴水浄化循環装置(A)を循環する状態と、前記循環路切換手段（１３）を動作させて、浴水の一部を前記入力側蓄熱配管（１１）を通して前記タンク（３０ａ）の下部から前記蓄熱槽（３０）に流入させて前記タンク（３０ａ）の上部から高温の浴水を前記出力側蓄熱配管（１２）から前記第1切換手段（１４）を経由して流出すると共に前記浴水浄化循環装置(A)を循環させた浴水の一部を前記第1切換手段（１４）で合流させて混合して前記出力側循環配管（６）から浴槽（１０）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（１１）を介して前記タンク（３０ａ）の下部から前記蓄熱槽（３０）に流入させて前記タンク（３０ａ）の上部から高温の浴水を前記出力側蓄熱配管（１２）を介して前記出力側循環配管（６）に流出して該出力側循環配管から高温の浴水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を特徴とする24時間浴水浄化循環装置とすることで、課題を解決することができた。
また、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を特徴とする請求項1又は2に記載の24時間浴水浄化循環装置とすることで、課題を解決することができた。
また、本発明は、浴槽（１０）内から浴水を循環ポンプ（１）により入力側循環配管（５）を介して流入し連結管（４）を循環させて該連結管（４）に連結された殺菌装置（２）と濾過装置（３）により殺菌及び微細なごみ不純物等を濾過して前記連結管（４）に連結する出力側循環配管（６）を通して浴槽（１０）に戻すようにした浴水浄化循環装置(A)と、前記連結管（４）に連結するタンク（３０ａ）内に電力利用のヒーター（３０ｂ）を設け、前記タンク（３０ａ）は下部に一端を連結した入力側蓄熱配管（１１）の他端を前記連結管（４）に設けた循環路切換手段（１３）を介して連結すると共に、前記タンク（３０ａ）の上部に一端を連結した出力側蓄熱配管（１２）を前記出力側循環配管（６）に連結してなり、入力側蓄熱配管（１１）からの浴水を流入してタンク（３０ａ）内の浴水を高温に保持する蓄熱槽（３０）と、浴水の温度を検知するための温度計測手段（２２）と、前記温度計測手段（２２）の検出温度に対応して、前記循環路切換手段（１３）を動作させて浴水を前記浴水浄化循環装置(A)を循環する状態と、前記循環路切換手段（１３）を動作させて、浴水の一部を前記入力側蓄熱配管（１１）を通して前記タンク（３０ａ）の下部から前記蓄熱槽（３０）に流入させて前記タンク（３０ａ）の上部から高温の浴水を前記出力側蓄熱配管（１２）から流出すると共に前記浴水浄化循環装置(A)を循環させた浴水の一部と合流させて混合して前記出力側循環配管（６）から浴槽（１０）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することで、課題を解決することができた。
【０００５】
【課題を解決しようとする手段】
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、循環ポンプの作動によって浴槽内の浴水を入力側循環配管から汲み上げて殺菌装置及び濾過装置が配備された浴水浄化循環装置を循環させて浄化処理した後に出力側循環配管から浴槽内に流出させて絶えず浴水を清浄に保つ２４時間浴水浄化循環装置において、底面に入力側蓄熱配管を、上面に出力側蓄熱配管をそれぞれ接続し、内部に電力利用のヒーターを設けて熱湯を貯える蓄熱槽を配備し、該蓄熱槽は、入力側蓄熱配管を浴水浄化循環装置の入力側循環配管に循環路切換手段を介して接続し、弁制御手段は、温度計測手段が計測した浴水温度に基いて、前記循環路切換手段を浴水浄化循環装置の入力側循環配管を流通する浴水が浴水浄化循環装置単独側方向、蓄熱槽単独側方向、及び浴水浄化循環装置並びに蓄熱槽両側方向の三方向に流通するように切り換え、前記蓄熱槽の出力側蓄熱配管から入力側蓄熱配管を経て流入した浴水の量に相当する量の熱湯が流出して浴水に混入し、加熱するよう制御する２４時間浴水浄化循環装置等としたことにより、蓄熱槽として夜間電力使用態様にすれば、飛躍的に、電力エネルギーコストを軽減することができ、更に、人体への安全性の確保、コスト、寿命などの点でもよく、前記の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（入力側）には、比較的粗いごみ等を除去可能なプレフィルタ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としての具体的構成としては、水を蓄熱媒体とした電気温水器が使用される。即ち、蓄熱槽３０は、タンク３０ａと、該タンク３０ａ内に設けた電力利用のヒーター３０ｂとから構成され、この中には、タンク３０ａの下側から、水道等の水源から給水され、上側から前記出力側蓄熱配管１２から給湯されるものである。このような電気温水器の原理としては、対流方式（自然対流，強制対流）や、熱交換器方式等があり、湯の中に水が入ってもその混合層（分離層）から上側が湯としてなり充分に温水器として使用できる。また、温度検知器３０ｃも設けられ、所望の設定温度にて制御されるようになっている。
【００１１】
蓄熱槽３０（温水器）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。
【００１２】
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。
【００１３】
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。
【００１４】
適宜の所望の設定温度範囲内（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内の蓄熱湯と、浴水浄化循環装置Ａ内の浴水とが混合されつつ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の流路としては、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〕。
【００１５】
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）。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。
【００１６】
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内の蓄熱湯と、浴水浄化循環装置Ａ内の浴水とが混合されつつ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間を浴水を含む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。
【００１７】
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、浴水を含む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。
【００１８】
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箇所から急速加熱配管１６が設けられ、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混合されつつ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間を浴水を含む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。
【００１９】
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に流出可能に設けている。浴水が温度低下した場合には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〕。このように、循環路切換手段１３の切換にて、入力側蓄熱配管１１に浴水が流入されると、その量だけ蓄熱槽３０内の蓄熱湯が出力側循環配管６から自動的に流出する。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。
【００２０】
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）の第１切換手段１４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。
【００２１】
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）の第１切換手段１４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。
【００２２】
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）の第１切換手段１４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。
【００２３】
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。
【００２４】
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。

【発明の効果】
請求項１の発明においては、循環ポンプ１の作動によって浴槽１０内の浴水を入力側循環配管５から汲み上げて殺菌装置２及び濾過装置３が配備された浴水浄化循環装置Ａを循環させて浄化処理した後に出力側循環配管６から浴槽１０内に流出させて絶えず浴水を清浄に保つ２４時間浴水浄化循環装置において、底面に入力側蓄熱配管１１を、上面に出力側蓄熱配管１２をそれぞれ接続し、内部に電力利用のヒーター３０ｂを設けて熱湯を貯える蓄熱槽３０を配備し、該蓄熱槽３０は、入力側蓄熱配管１１を浴水浄化循環装置Ａの入力側循環配管５に循環路切換手段１３を介して接続し、弁制御手段２３は、温度計測手段２２が計測した浴水温度に基いて、前記循環路切換手段１３を浴水浄化循環装置Ａの入力側循環配管５を流通する浴水が浴水浄化循環装置Ａ単独側方向、蓄熱槽３０単独側方向、及び浴水浄化循環装置Ａ並びに蓄熱槽３０両側方向の三方向に流通するように切り換え、前記蓄熱槽３０の出力側蓄熱配管１２から入力側蓄熱配管１１を経て流入した浴水の量に相当する量の熱湯が流出して浴水に混入し、加熱するよう制御する２４時間浴水浄化循環装置としたことにより、浴水の水温を一定に保つのに水を電源にて加熱可能にする蓄熱槽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、蓄熱媒体として水を用いているため蓄熱材のコストが低くできるし、蓄熱槽３０を並列に配置しているため、浴槽水の温度管理が容易である。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。
【００２６】
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、蓄熱媒体として水を用いているため蓄熱槽３０の装置設置の際、蓄熱材を容易にセットできるし、引火性が無く安全である。さらには、熱交換器に穴などがあいても浴槽水の汚染の心配がなく、腐食性が低い等の利点がある。
【００２７】
請求項２の発明においては、循環ポンプ１の作動によって浴槽１０内の浴水を入力側循環配管５から汲み上げて殺菌装置２及び濾過装置３が配備された浴水浄化循環装置Ａを循環させて浄化処理した後に出力側循環配管６から浴槽１０内に流出させて絶えず浴水を清浄に保つ２４時間浴水浄化循環装置において、底面に入力側蓄熱配管１１を、上面に出力側蓄熱配管１２をそれぞれ接続し、内部に電力利用のヒーター３０ｂを設けて熱湯を貯える蓄熱槽３０を配備し、該蓄熱槽３０の出力側蓄熱配管１２は、浴水浄化循環装置Ａの出力側循環配管６に急速加熱配管１６が接続する切換手段を介して接続し、弁制御手段２３は、入力側循環配管５に設けた循環路切換手段１３の切換に応じて出力側循環配管６に設けた切換手段を切り換え、前記循環路切換手段１３を蓄熱槽３０単独側方向に切り換えた際には、前記切換手段を急速加熱配管１６単独側に切り換えて出力側蓄熱配管１２に流出した熱湯が浴槽１０に直接流出するように制御する２４時間浴水浄化循環装置としたことにより、浴水の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。
【００２８】
請求項３の発明においては、前記浴水浄化循環装置にシーズヒーター等の加熱手段１８をさらに配備した請求項１又は請求項２記載の２４時間浴水浄化循環装置としたことにより、寒冷地等の使用に対して有効である。

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.
[0013]
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.
[0014]
Within an appropriate desired set temperature range (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 but passes only through the bath water purification and circulation apparatus A. The flow path of the 1st switching means 14 is comprised so that only the inside of the bath water purification circulation apparatus A may pass (refer 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. Also passes through the output-side circulation pipe 6 while being mixed with the hot water in the heat storage tank 30 and the bath water in the bath water purification / circulation device A via the first switching means 14. [Refer to FIG. 3 (B)].

Only, 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 the hot water stored only in the heat storage tank 30 is supplied from the output side circulation pipe 6. It is configured to pass through (see FIG. 3C).
[0015]
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). With this lowered, the process returns to the position before step S1.
[0016]
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 stored hot water in the heat storage tank 30 and the bath water in the bath water purification / circulation device A are mixed and pass through the output side circulation pipe 6 [FIG. (See (B)). 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. Further, when the temperature is greatly reduced (about several degrees or more) (in the case of S5 NO), valve control is performed by the valve control means 23, and hot water containing bath water circulates between the heat storage tanks 30 and bath water. The temperature 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.
[0017]
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, only when it passes through the bath water purification / circulation device A without flowing out to the input side heat storage pipe 11 (see FIG. 3A) and only the hot water containing bath water. May flow out into the bathtub 10 (see FIG. 3C).
[0018]

In this case, the rapid heating pipe 16 is provided from the 15 second switching means, and 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 hot water is circulated while being mixed to raise the bath water temperature (see FIGS. 7B and 7C). In particular, in the case of FIG. 7B, the 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 flowed out at an appropriate temperature. It is the case. Further, when the temperature is greatly lowered (about several degrees or more), the hot water containing bath water circulates between the heat storage tanks 30 to raise the bath water temperature [see FIG. 7 (D)]. The flowchart is the same as that in the first embodiment.
[0019]
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. Each end is provided in the bathtub 10 so as to be able to flow out. When the temperature of the bath water drops, this 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. Has been. 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). As described above, when the bath water flows into the input side heat storage pipe 11 by switching the circulation path switching means 13, the hot water in the heat storage tank 30 automatically flows out from the output side circulation pipe 6 by that amount. . Other configurations are the same as those of the first embodiment, and the description thereof is omitted.
[0020]
