Description

【０００１】
【発明の属する技術分野】
本発明は風呂装置に係り、特に浴槽内の湯を強制的に循環させつつ濾過、殺菌等の清浄化処理すると同時に入浴者が設定した温度に保温し、浴槽湯を絶えず清浄かつ適温保ち２４時間何時でも好みの時に入浴できるようにしたいわゆる２４時間風呂装置に関するものである。
【０００２】
【従来の技術】
最近、浴槽内の湯を絶えず清浄かつ適温に保ち、２４時間いつでも快適に入浴でき、しかも水の節約にもなる、浴槽湯の清浄化装置、すなわち２４時間風呂の利用が盛んになつてきた。
【０００３】
このような浴槽湯の清浄化装置の１例は図６に示す通りであり、１が浴槽、２が湯、３が浴槽１内の湯２を汲み上げるための吸湯管、４が吸湯管３で汲み上げられた湯を清浄化処理するための機器類をまとめて配備した装置本体、９が装置本体４で処理された湯を浴槽１内に再び噴出させるための噴湯管である。
【０００４】
装置本体４には、浴槽湯中の汚れを取り除くため、活性炭、活性石、多孔質セラミツクボール等の各種の粒状濾材や繊維状フイルタが単独或いは複合して装填された濾過タンク５、湯を強制循環するための循環ポンプ６、湯を適温に保つための保温用の電気ヒータ７、湯に対するオゾン殺菌装置としてのオゾナイザ８等の清浄化処理機器が配備されている。
【０００５】
１０は大きな汚れを装置本体４に汲み上げる前に予め取り除くため吸湯管３の先端に取り付けたプレフイルタであり、１１は清浄化処理の終わった湯を流速の早いジエツト流として浴槽１内に噴出する吸気管１２がエジエクタ部に接続するジエツトノズルである。
【０００６】
ジエツトノズル１１のエジエクタ部に接続する吸気管１２の先端には管路を開閉するための電磁弁１３が設けられ、途中にオゾナイザ８が配備されていて、電磁弁１３を開くとジエツトノズル１１の吸気力で吸気管１２から空気が吸い込まれ、この空気がエジエクタ部２４で湯に混入されジエツトノズル１１からジエツト流が浴槽１内に噴出して泡風呂となり、さらにオゾナイザ８を作動させると吸気管１２に吸い込まれた空気がオゾン化されて浴槽１内に噴出され湯２がオゾン殺菌される。
【０００７】
【発明が解決しようとする課題】
しかしながら、以上のように構成される装置では湯の加熱を電気ヒータで行っているのでランニングコストが高くなり、またこの電気ヒータの容量は配線容量の関係では８００Ｗ程度とするのが限度なので、２００リットルもの浴槽湯を加熱するには容量が不足で加熱速度が遅くなる。
【０００８】
この結果、入浴の際に湯の温度を上げたくてもなかなか上がらず、さらに湯の交換をした際や装置の運転を長時間止めていたために湯温が大幅に下がってしまった際には、湯を入浴温度まで加熱するのに非常に長い時間が掛かってしまう。
【０００９】
本発明は前記したような従来技術の欠点を解消し、加熱費を安くすると共に急速に湯を入浴者が設定した温度まで加熱し、設定温度に達した後には設定温度で正確に保温できるようにした浴槽湯の清浄化装置を提供することを目的とする。
【００１０】
【課題を解決するための手段】
すなわち本発明は、浴槽内の湯を循環ポンプにより吸湯管から汲み上げ清浄化管路を強制循環させて濾過タンクによる濾過処理、殺菌装置による殺菌処理をした後噴湯管から浴槽に再び噴出させる浴槽湯の清浄化装置において、前記濾過タンクで濾過処理された湯を分岐して流入させて熱交換により加熱する追焚装置を設けると共に、前記清浄化管路に湯温調節器を配備し、該湯温調節器は、前記追焚装置からの熱湯供給管が接続して追焚装置での加熱により生成した熱湯を流入させる熱湯流入口と、前記清浄化管路に接続して該清浄化管路を循環する浴槽湯を流入させる浴槽湯流入口と、該浴槽湯流入口からの浴槽湯と前記熱湯流入口からの熱湯とが流入し、浴槽湯に熱湯を混合する混合室と、該混合室に前記清浄化管路を接続して熱湯が混合された浴槽湯を清浄化管路に流出させる浴槽湯流出口と、混合室に装着された混合室内に位置するサーモエレメントの混合室内の湯温に応じてピストンが上下動し、ピストンに固着した弁が開閉するサーモスタット式流量調整弁とからなり、浴槽湯流入口は混合室と直接連通し、熱湯流入口は前記サーモスタット式流量調整弁を介して混合室と連通し、混合室内で、清浄化管路から直接流入した浴槽湯に、熱湯流入口からサーモスタット式流量調節弁により熱湯が混合された浴槽湯の湯温に応じて熱湯の流量を調節して混合させて浴槽湯の湯温を調節し、浴槽湯流出口から清浄化管路に流出させると共に、湯温設定キーにより入力された設定温度に応じてモータを動作させて、前記サーモスタット式流量調整弁の熱湯混入上限を規制して、湯温を設定する自動湯温設定装置を備えることを特徴とする浴槽湯の清浄化装置とすることにより課題を解決した。
また本発明は、浴槽内の湯を循環ポンプにより吸湯管から汲み上げ清浄化管路を強制循環させて濾過タンクによる濾過処理、殺菌装置による殺菌処理をした後噴湯管から浴槽に再び噴出させる浴槽湯の清浄化装置において、水道に接続された入水管を熱交換器に接続し、水道水を流入させて熱交換により加熱する追焚装置を設けると共に、前記清浄化管路に湯温調節器を配備し、該湯温調節器は、前記追焚装置からの熱湯供給管が接続して追焚装置での加熱により生成した熱湯を流入させる熱湯流入口と、前記清浄化管路に接続して該清浄化管路を循環する浴槽湯を流入させる浴槽湯流入口と、該浴槽湯流入口からの浴槽湯と前記熱湯流入口からの熱湯とが流入し、浴槽湯に熱湯を混合する混合室と、該混合室に前記清浄化管路を接続して熱湯が混合された浴槽湯を清浄化管路に流出させる浴槽湯流出口と、混合室に装着された混合室内に位置するサーモエレメントの混合室内の湯温に応じてピストンが上下動し、ピストンに固着した弁が開閉するサーモスタット式流量調整弁とからなり、浴槽湯流入口は混合室と直接連通し、熱湯流入口は前記サーモスタット式流量調整弁を介して混合室と連通し、混合室内で、清浄化管路から直接流入した浴槽湯に、熱湯流入口からサーモスタット式流量調節弁により熱湯が混合された浴槽湯の湯温に応じて熱湯の流量を調節して混合させて浴槽湯の湯温を調節し、浴槽湯流出口から清浄化管路に流出させると共に、湯温設定キーにより入力された設定温度に応じてモータを動作させて、前記サーモスタット式流量調整弁の熱湯混入上限を規制して、湯温を設定する自動湯温設定装置を備えることを特徴とする浴槽湯の清浄化装置とすることにより課題を解決した。
【００１１】
さらに本発明は、前記流量調節弁が浴槽湯の湯温に応じて体積変化するサーモエレメントにより可動するピストンを作動して開閉することで、課題を解決した。
さらに本発明は、前記自動湯温設定装置が前記温度設定手段で設定された設定温度に応じて前記ピストンの作動範囲を自動的に規制することで、課題を解決した。
【００１２】
また、本発明は、浴槽内の湯を循環ポンプにより汲み上げて清浄化管路を循環させ、濾過タンクにより汚れを濾過し、殺菌装置により殺菌し、加熱装置により保温加熱した後浴槽内に再び噴出させる浴槽湯の清浄化装置において、前記清浄化管路に開閉弁を介して熱湯の供給口を接続した湯温を調節する手段を備え、熱交換器を循環する湯を燃焼バーナによって加熱して熱湯を生成して供給する手段を前記供給口に接続すると共に、前記湯温を調節する手段の開閉弁は浴槽湯の湯温に応じて開閉量が定量的に変化する弁として、生成した熱湯を浴槽湯の湯温に応じた量だけ混合して湯温を調節した後浴槽に噴出させることを特徴とする浴槽湯の清浄化装置としたことで、課題を解決した。
【００１３】
【発明の詳細な説明】
【００１４】
【発明の実施の形態】
次に本発明の実施の形態について、図１の実施例の配管図に基づいて説明するが、従来例と同一の構成要素には同一の符号を付けてある。
【００１５】
清浄化管路１４には、湯を清浄化の場合の逆に流して濾過タンク５に充填された濾材を洗浄するいわゆる逆洗の管路を形成するために、Ｌ字型及びＴ字型の切換弁１５及び１６が配備されている。
【００１６】
また殺菌装置として紫外線殺菌装置１７を配備したが、勿論従来例のように吸気管１２を噴湯管９の先端に取り付けたジエットノズル１１に接続し泡風呂を楽しめるようにしたり、吸気管１２の途中にオゾナイザ８を配備してオゾン殺菌できるようにしても良い。
【００１７】
１８が後に詳細な構成を説明する湯温調節器であり、この湯温調節器１８には浴槽湯流入口１９、熱湯流入口２０及び浴槽湯流出口２１が設けられると同時に、浴槽湯流入口１９から流入した浴槽湯の温度に応じて弁が開閉する流量調節弁２２が熱湯流入口２０に対して配備してある。
【００１８】
２３が自動湯温設定装置であり、入浴者が湯温を設定する湯温設定キー２４、湯温調節器１８の熱湯流入口２０に対して配備された流量調節弁２２の作動範囲の調節部材を駆動するパルスモータ２５、及び湯温設定キー２４で設定された温度に応じてパルスモータ２５の駆動を制御するマイクロコンピユータであるモータ制御装置２６とから成り、湯温調節器１８の熱湯流入口２０に対して配備された流量調節弁２２の作動範囲を湯温設定キー２４での設定温度に応じて自動的に調節する。
【００１９】
２７は追焚装置であり、この追焚装置２７には、入湯管２９と熱湯供給管としての出湯管３０とを両端に接続した熱交換器２８と、この熱交換器２８を流れる湯を追焚するガス或いは灯油を熱源とする燃焼バーナ３１とが配備されている。
【００２０】
３２は入湯管２９の途中に配備された水流センサであり、この水流センサ３２が入湯管２９に湯が流れているのを検知した際に限って燃焼バーナ３１を点火する。
【００２１】
追焚装置２７の出湯管３０は熱湯供給管として湯温調節器１８の熱湯流入口２０に接続し、入湯管２９は湯温調節器１８の上流で清浄化管路１４に接続している。
【００２２】
このようにして追焚装置２７を清浄化管路１４に接続すると、湯温調節器１８に浴槽湯流入口１９から入った浴槽湯２の温度が設定温度より低くなって流量調節弁２２が開くと、清浄化管路１４を流れている浴槽湯２の一部は入湯管２９を経て追焚装置２７にも流れる。
【００２３】
入湯管２９に浴槽湯２が流れると、前記したように水流センサ３２がこれを検知して燃焼バーナ３１が点火されるので、追焚装置２７に流れ込んだ浴槽湯２は熱交換器２８で熱交換されて熱湯となって熱湯供給管としての出湯管３０から流出し、湯温調節器１８に熱湯流入口２０から入る。
【００２４】
すると湯温調節器１８では、浴槽湯流入口１９から入った設定温度以下になった浴槽湯を、追焚装置２７で一部の浴槽湯２を追焚して作った熱湯を混合して加熱した後浴槽湯流出口２１から清浄化管路１４に再び流出する。
【００２５】
前記第１実施例では、湯温調節器１８で設定温度以下になった浴槽湯２を加熱するための熱湯を、清浄化管路１４を流れている浴槽湯２の一部を熱湯流入口２１に対して配備した流量調節弁２２が開いた際に追焚装置２７に流入させて作っている。
【００２６】
これに対して図２に示す第２実施例では、湯温調節器１８で設定温度以下になった浴槽湯２を加熱する熱湯を、水道３３と追焚装置２７の熱交換器２８とを入水管３４で接続し、水道水を加熱して作るようにしている。
【００２７】
このような構成とすると、点線で示したように追焚装置２７の出湯管３０から給湯管を分岐しシヤワー及び給湯口を接続すると、シヤワーが利用できると同時に浴槽１に対しての湯張りや足し湯もできて好都合である。
【００２８】
湯温調節器１８の構成について図３及び図４に基づいて詳細を説明すると、図３において、３５が混合室であり、この混合室３５は、上面が中央に弁穴３７を設けた弁座３６となっており、１つの側面には浴槽湯流入口１９が、他の側面には弁穴３７に対して流量調節弁２２を配備した弁座３６に通じた熱湯流入口２０が設けられ、下面には浴槽湯流出口２１が設けられている。
【００２９】
流量調節弁２２の構成を説明すると、弁軸３８は、下端に弁座３６の弁穴３７を開閉するための弁筒３９が固定して取り付けられ、内部に混合室３５に流入した浴槽湯２の湯温に応じて体積が変化するサーモエレメントとしてのワックス４１が充填され、このワックス４１に下端が当たるピストン４２が上下動自在にはめられたサーモスタット４０が固定してはめられている。
【００３０】
４３は流量調節弁２２の弁軸３８を上下動自在にはめるため混合室３５の上方に延びた案内管であり、４４は案内管３９の上端にはめられ浴槽湯の設定温度に応じてピストン４２の作動範囲を調節する押さえ軸であり、４５は流量調節弁２２を上の方に押し上げるための複数の押さえばねである。
【００３１】
前記したピストン４２の上端を押さえて流量調節弁２２の作動範囲を調節する部材である押さえ軸４４に対しては自動湯温設定装置２３のパルスモータ２５の回転軸がが取り付けられている。
【００３２】
この結果流量調節弁２２は、押さえ軸４４が自動湯温設定装置２３により湯温設定キー２４で設定した湯温に応じてモータ制御装置２６で制御されるパルスモータ２５で駆動されて自動的に上下動して位置が決めされ、設定された湯温に応じて作動範囲が調節されるようになっている。
【００３３】
流量調節弁２２の弁軸３８の下端に固定して取り付けられる弁筒３９は図４に示す通りであり、上半分は弁座３６の弁穴３７を塞ぐ円筒である閉湯筒４６となっており、下半分は所定の間隔で複数の切り欠き溝４８を通湯溝として設けた円筒である通湯筒４７となっており、中央に弁軸３８に取り付けるための取付穴４９が設けられている。
【００３４】
したがって流量調節弁２２は、弁筒３９を取付穴４９を介して弁軸３８の下端に取り付けた後、混合室３５に対して、弁筒３９を弁座３６の弁穴３７に、弁軸３８を案内管４３に上下動自在にはめ、複数の押さえばね４５で上に向かって押し上げ、ピストン４２の上端を押さえ軸４４で上から押さえながら配備する。
【００３５】
この結果流量調節弁２２は、弁筒３９が上の方に押し上げられて弁が開き、同時に押さえ軸４４が自動湯温設定装置２３により、設定された湯温に応じて位置決めされて作動範囲を調節した状態で配備されている。
【００３６】
以上のような構成の湯温調節器１８を用いて清浄化管路１４を強制循環する浴槽湯の湯温を追焚装置２７での追焚きにより作られた熱湯で加熱し適温を保つ状態を図５に基づいて説明する。
【００３７】
まず装置の運転を開始する際には、湯温調節器１８は、（ａ）図に示すように、流量調節弁２２が押さえばね４５により上の方に押されて弁筒３９は通湯筒４７が混合室３５の弁穴３６に位置していて弁が開き、しかも自動湯温設定装置２３により流量調節弁２２の作動範囲を湯温設定キー２４で設定された温度に応じて調節した初期設定状態になっている。
【００３８】
この状態で装置の運転が開始されると、切換弁１５及び１６が清浄化の処理の方向に切り換えられているので、循環ポンプ６で吸湯管３から汲み上げられた浴槽１内の湯２は、紫外線殺菌装置１７で殺菌された後濾過タンク５で濾過され清浄化管路１４を流れて行く。
【００３９】
この際前記したように湯温調節器１８の熱湯流入口２０は、配備された流量調節弁２２が開いて熱湯が流入できる状態になっているので、追焚装置２７では、第１実施例の配管では清浄化管路１４と接続した入湯管２９から浴槽湯２の１部が、第２実施例の配管では水道３３と接続する入水管３４から水道水が流入し燃焼バーナ３１が点火して追焚されて熱湯が作られる。
【００４０】
この結果湯温調節装置１８には清浄化管路を流れた浴槽湯２が浴槽湯流入口１９から入ると同時に、追焚装置２７で作られた熱湯が熱湯供給管としての出湯管３０を経て熱湯流入口２０から入る。
【００４１】
そこで湯温調節器１８では、混合室３５で清浄化管路１４を循環して湯温調節器１８に入った浴槽湯２には追焚装置２７で追焚して作られた熱湯が混合されて加熱され浴槽湯流出口２１から再び清浄化管路１４に出て、浴槽１に噴湯管９から戻る。
【００４２】
このようにして（ａ）図に示すように湯温調節器１８の熱湯流入口２０に対する流量調節弁２２が開き、混合室３１で追焚装置２３で作られた熱湯が混合され加熱される状態が続くと、清浄化管路１４を循環し湯温調節器１８に流入する浴槽湯２の温度は上がり続ける。
【００４３】
すると湯温調節器１８の熱湯流入口２０に対して配備された流量調節弁２２は、サーモスタット４０に充填されたサーモエレメントであるワックス４１の温度が上がって体積が膨張しピストン４２を上に押し上げるようになる。
【００４４】
ところがピストン４２は湯の設定温度に応じ位置の押さえ軸４４で上端が押さえられているので、流量調節弁２２は徐々に下に向かって弁を閉じる方向に動きだし、浴槽湯２の温度が入浴者が設定した温度と同じになり、（ｂ）図に示すような弁が閉じた瞬間の状態になる。
【００４５】
すなわち浴槽湯２の温度が上がり流量調節弁２２がサーモスタット４０のワックス４１の体積が膨張し下がり続けると、混合室３５の弁座３６の弁穴３７にはめられている弁筒３９が下がり続け、浴槽湯２と設定温度とが同じになった瞬間には閉湯筒４６の下端が丁度弁穴３７の位置に来るまで下がり弁を閉じ熱湯流入口２０から熱湯が入らな状態になる。
【００４６】
すると追焚装置２７には入湯管２９からの浴槽湯２或いは入水管３４からの水道水が入らない状態になり、これを水流センサ３２が検知して燃焼バーナ３１は消火し熱湯は作られなくなり、清浄化管路１４を循環する浴槽湯２は湯温調節器１８では熱湯が混合され加熱されることなくそのまま浴槽１に戻って行く。
【００４７】
（ｂ）図に示すように、湯温調節器１８の熱湯流入口２０に対する流量調節弁２２の弁が閉じ、浴槽湯２は加熱されないで清浄化管路１４を循環し続けるとやがて温度が下がり出す。
【００４８】
すると流量調節弁２２は、サーモスタット４０のワックス４１の体積は収縮し出すのでピストン４２を上に押す力は弱くなって上に上がり、弁筒３９は通湯筒４７が弁座３６の弁穴３７に対して位置し弁が開いた（ａ）図に示すようになり、清浄化管路１４を循環している浴槽湯２は、湯温調節器１８で追焚装置２７で作った熱湯が混合されて再び加熱されてから浴槽１に戻るようになる。
【００４９】
以上のようにして湯温調節されながら清浄化管路１４を循環している浴槽湯２は、前記したように温度が設定温度と同じになった瞬間に湯温調節器１８の熱湯流入口２０に対して配備した流量流量調節弁２２の弁が閉じこれより高くなり過ぎることはない。
【００５０】
しかも流量調節弁２２の作動範囲が設定された湯温に応じて自動湯温設定装置２３７により正確に調節されているので、湯は一層正確に設定温度に保たれる。
【００５１】
すなわち目盛りを目安にしてつまみを手で廻して湯温を設定して流量調節弁２２の作動範囲を手動調節する場合には、あまり正確に湯温が設定できない。
【００５２】
すると流量調節弁２２は、浴槽湯の温度に基づいて正確に弁の開閉をしても、設定温度が正確に設定できていないので、設定温度に応じて位置決めされる押さえ軸４４の位置がばらつき作動範囲が設定温度に対して正確に調節されていないので、浴槽湯の温度は入浴者が設定したと思う温度に対してかなりばらついてしまう。
【００５３】
ところが流量調節弁２２は、作動範囲を自動湯温設定装置２３により調節するすると、先ず入浴者は湯温設定キー２４で正確に湯温を設定でき、次いでこの正確に設定した湯温に基づいて押さえ軸４４が正確に位置決めされて作動範囲が正確に調節されるので、浴槽湯は正確に設定温度に保たれる。
【００５４】
さらに、浴槽湯２が何らかの原因で加熱され過ぎて設定温度よりも高くなってしまっても、（ｃ）図に示すように、湯温調節器１８の熱湯流入口２０に対する流量調節弁２２が完全に閉じ、浴槽湯２は、温度が設定温度よりも下がるまでは熱湯が絶対混ざらないでそれ以上温度が高くなり過ぎることは絶対にない状態になる。
【００５５】
すなわち浴槽湯２の温度が設定温度よりも高くなると、湯温調節器１８の流量調節弁２２は、サーモスタット４０のワックス４１の膨張が続くので下がり続け、やがて混合室３５の弁座３６の弁穴３７は弁筒３９の閉湯筒４６の上端で塞がれ完全に弁が閉じた状態になる。
【００５６】
このようになると浴槽湯２が、加熱されないで清浄化管路１４を循環し続けて温度が次第に下がり、湯温調節器１８の流量調節弁２２が、サーモスタット４０のワックス４１が収縮しピストン４２を上に押す力が弱くなって徐々に上がり出し、やがて設定温度と同じになって（ｂ）図に示すような状態を経た後、設定温度よりも下がって（ａ）図に示すような再び弁が開いた状態になるまでは、追焚装置２７で作られた熱湯では絶対に加熱されない。
【００５７】
以上のように湯温調節器１８は、浴槽湯の温度が設定温度と同じになると同時に熱湯流入口２０対して配備した流量調節弁２２が閉じられて追焚装置２７で作られた熱湯を混合しての加熱が止められるので、浴槽湯２は必ず設定温度かそれ以下になっていて、高くなり過ぎることは殆どない。
【００５８】
仮に浴槽湯２が設定温度よりも高くなったとしても、流量調節弁２２は浴槽湯２の温度が上がるにつれて弁をしっかりと閉じる方向に動き、設定温度より下がるまでは絶対に弁を開かないので、この間にさらに熱湯が混合されてやけどの危険があるような熱すぎる状態には決してならない。
【００５９】
また湯温調節器１８は、浴槽湯２の清浄化管路１４の途中に流量調節弁２２を熱湯流入口２０に対して設けた状態で配備され、常に低温の浴槽湯２が流入し続け、浴槽湯２の湯温が設定温度より下がった場合に限って弁を開いて追焚装置２７で作った熱湯を混合して浴槽湯２の温度を調節するようにしているので、仮に弁が故障しても浴槽１に熱湯が噴出することがなくて安全である。
【００６０】
すなわち流量調節弁２２が故障して、弁が閉じた状態のままになると、浴槽湯２は追焚装置２７で作った熱湯を混合して加熱されないで設定温度より低い状態で浴槽１に噴出し続けるだけで危険はなく、弁が開いた状態のままになっても、必ず低温の浴槽湯２と熱湯とが混合された状態でとなるので、設定温度より高かくなり過ぎても決してやけどの危険がないような温度の浴槽湯２が浴槽１に噴出されるだけで、追焚装置２７で作った熱湯だけが浴槽１に噴出してしやけどしてしまうような危険はない。
【００６１】
なお湯温調節器１８の熱湯流入口２０に対して配備する流量調節弁２２をサーモスタット式とすると、弁が浴槽湯２の温度に応じて上下して開閉するので、所定の温度で単にＯＮ−ＯＦＦするだけの電磁弁式よりもはるかに精密な温度制御ができる。
【００６２】
また流量調節弁２２は、単に弁板で弁穴３７を開閉する構成としても良いが、実施例に示すように、閉湯筒４６と通湯筒４７とに２分した弁筒３９を弁穴３７に上下動自在にはめた構成にすると、弁の開閉が一層精密になって正確な温度調節ができるようになる。
【００６３】
すなわち、浴槽湯２の温度が設定温度より低すぎる場合に流量調節弁２２は通湯溝としての切り欠き溝４８を設けた通湯筒４７が弁座３６の上に出て弁を開くようになるが、この弁座３６の上に出る通湯筒４７の長さすなわち通湯面積である弁を開く量は浴槽湯２の温度に応じて変わるようになっている。
【００６４】
このため湯温調節器１８は、浴槽湯２が設定温度よりも低く流量調節弁２２を開いて加熱する際に、混合室３５には設定温度と浴槽湯２との温度差に比例した量の熱湯が追焚き装置２７で作られて熱湯流入口２０から入るようになり、浴槽湯２を素早くしかも正確に設定湯温まで加熱する。
【００６５】
しかも浴槽湯２が設定温度に達した瞬間には弁が閉じられ混合室３５には熱湯が入らないようになるので、浴槽湯２が設定温度以上になることは殆どない。
【００６６】
一方浴槽湯の温度が設定温度よりも高くなり過ぎ流量調節弁２２を閉じる際には、弁座３７の下に出る閉湯筒４６の長さすなわち弁を閉じる量も浴槽湯２と設定温度との温度差に比例していて、浴槽湯２が設定温度よりも高か過ぎれば高か過ぎるほど弁を完全に閉じた状態にして、浴槽湯２が設定温度以下になるまでは決して開かないで温度調節を正確にすると同時に浴槽湯２が熱くなりすぎるのを完全に防いでいる。
【００６７】
なお湯温調節器１８の熱湯流入口２０に対して配備する流量調節弁としては、前記実施例に示すようなサーモスタット式が好ましいが、バイメタル式或いは形状記憶合金式等の浴槽湯の温度に応じて自動的に弁を開閉できるなら他の形式の弁を利用しても良いことは言うまでもないことである。
【００６８】
またサーモスタット式の流量調節弁においてもサーモエレメントととして、ワックス以外の例えば気体や低融点合金といった熱に敏感に感応して大きく体積変化する材料を利用しても良い。
【００６９】
【発明の効果】
本発明は以上のように構成され、清浄化管路１４の途中に配備した湯温調節器１８により、浴槽湯２を追焚装置２７で作った熱湯を湯温に応じて適量混合して加熱し、熱湯が直接浴槽１に噴出しない安全な状態で正確に温度調節をする。
【００７０】
しかも湯温調節器１８に配備する流量調節弁２２には自動湯温設定装置２３を配備し、浴槽湯２を入浴者が設定した温度に一層正確に温度調節する。
【００７１】
また浴槽湯２に湯温に応じて混合する熱湯は、ガス或いは灯油といった燃料を利用して追焚装置で作られるので、電気加熱と比べて加熱費がはるかに安くなると同時に加熱速度もずっと速くなる。

The present invention relates to a so-called 24-hour bath apparatus that can take a bath whenever desired.
[0002]
[Prior art]
Recently, bath hot water purifiers, ie, 24-hour baths, that keep hot water in a bathtub constantly clean and at an appropriate temperature, can be comfortably bathed anytime for 24 hours, and save water, have become popular.
[0003]
One example of such a bath water purifier is as shown in FIG. 6, where 1 is a bathtub, 2 is hot water, 3 is a hot water pipe for pumping up hot water 2 in the bathtub 1, and 4 is a hot water pipe. 3 is an apparatus main body in which devices for purifying the hot water pumped up in 3 are arranged together, and 9 is a fountain pipe for causing the hot water processed in the apparatus main body 4 to be ejected into the bathtub 1 again.
[0004]
In order to remove dirt in the bath water, the apparatus main body 4 is forced to have a filtration tank 5 loaded with various granular filter media such as activated carbon, activated stone, porous ceramic balls, or a fibrous filter alone or in combination, and hot water. A cleaning pump such as a circulation pump 6 for circulation, an electric heater 7 for keeping hot water at an appropriate temperature, and an ozonizer 8 as an ozone sterilizer for hot water are provided.
[0005]
Reference numeral 10 denotes a prefilter attached to the tip of the hot water suction pipe 3 in order to remove large dirt before pumping it up into the apparatus main body 4. Reference numeral 11 denotes hot water after the cleaning process is jetted into the bathtub 1 as a jet flow having a high flow velocity. The intake pipe 12 is a jet nozzle connected to the ejector section.
[0006]
An electromagnetic valve 13 for opening and closing the pipe line is provided at the tip of the intake pipe 12 connected to the ejector portion of the jet nozzle 11, and an ozonizer 8 is provided in the middle.

DETAILED DESCRIPTION OF THE INVENTION
[0014]
DETAILED DESCRIPTION OF THE INVENTION
Next, an embodiment of the present invention will be described based on the piping diagram of the embodiment of FIG. 1, but the same components as those in the conventional example are denoted by the same reference numerals.
[0015]
In order to form a so-called backwash conduit for cleaning the filter medium filled in the filtration tank 5 by flowing hot water in the reverse direction in the case of cleaning, the cleaning conduit 14 has an L-shape and a T-shape. Switching valves 15 and 16 are provided.
[0016]

[0017]
Reference numeral 18 denotes a hot water temperature regulator whose detailed configuration will be described later. The hot water temperature regulator 18 is provided with a bathtub hot water inlet 19, a hot water inlet 20, and a bathtub hot water outlet 21, and at the same time, a bathtub hot water inlet. A flow rate adjustment valve 22 that opens and closes according to the temperature of the bath water flowing in from 19 is provided for the hot water inlet 20.
[0018]
Reference numeral 23 denotes an automatic hot water temperature setting device, a hot water temperature setting key 24 for the bather to set the hot water temperature, and an operating range adjusting member for the flow rate adjusting valve 22 provided for the hot water inlet 20 of the hot water temperature regulator 18. And a motor control device 26 which is a micro computer for controlling the driving of the pulse motor 25 in accordance with the temperature set by the hot water temperature setting key 24, and the hot water inlet of the hot water temperature regulator 18. 20 automatically adjusts the operating range of the flow rate adjusting valve 22 provided for 20 according to the temperature set by the hot water temperature setting key 24.
[0019]
Reference numeral 27 denotes a chasing device, and in the chasing device 27, a heat exchanger 28 in which a hot water pipe 29 and a hot water supply pipe 30 as a hot water supply pipe are connected to both ends, and hot water flowing through the heat exchanger 28 are chased. A combustion burner 31 using a gas or kerosene as a heat source is provided.
[0020]
A water flow sensor 32 is provided in the middle of the hot water pipe 29, and ignites the combustion burner 31 only when the water flow sensor 32 detects that hot water is flowing in the hot water pipe 29.
[0021]
The hot water supply pipe 30 of the remedy device 27 is connected as a hot water supply pipe to the hot water inlet 20 of the hot water temperature regulator 18, and the hot water inlet pipe 29 is connected to the cleaning line 14 upstream of the hot water temperature controller 18.
[0022]
When the remedy device 27 is connected to the cleaning conduit 14 in this way, the temperature of the bath water 2 entering the hot water temperature regulator 18 from the bath water inlet 19 becomes lower than the set temperature, and the flow rate control valve 22 is opened. Then, a part of the bathtub hot water 2 flowing through the cleaning pipe 14 also flows into the memorial device 27 through the hot water pipe 29.
[0023]
When the bath water 2 flows into the hot water pipe 29, the water flow sensor 32 detects this and the combustion burner 31 is ignited as described above, so that the bath water 2 that has flowed into the memory device 27 is heated by the heat exchanger 28. The hot water is exchanged and flows out from the hot water supply pipe 30 serving as the hot water supply pipe, and enters the hot water temperature regulator 18 through the hot water inlet 20.
[0024]
Then, the hot water temperature controller 18 mixes and heats the hot water bathed in the bath water inlet 19 through the bath device 2 that has become below the set temperature with the hot water device 27 that has been used to commemorate some bath water 2. After that, it flows out again from the bathtub hot water outlet 21 to the cleaning conduit 14.
[0025]
In the first embodiment, hot water for heating the bath water 2 that has become below the set temperature by the hot water temperature regulator 18 is used, and a part of the bath water 2 that flows through the cleaning conduit 14 is used as the hot water inlet 21. When the flow control valve 22 provided for the valve is opened, it is made to flow into the remedy device 27.
[0026]
On the other hand, in the second embodiment shown in FIG. 2, hot water for heating the bathtub hot water 2 that has become below the set temperature by the hot water temperature regulator 18 is inserted into the water supply 33 and the heat exchanger 28 of the memory device 27. It connects with the water pipe 34 and heats and makes tap water.
[0027]
With such a configuration, as shown by the dotted line, when the hot water pipe is branched from the hot water outlet pipe 30 of the remedy device 27 and the shower and hot water outlet are connected, the shower can be used and at the same time, It is convenient to add additional hot water.
[0028]
The configuration of the hot water temperature regulator 18 will be described in detail with reference to FIGS. 3 and 4. In FIG. 3, reference numeral 35 denotes a mixing chamber, and the mixing chamber 35 has a valve seat having a valve hole 37 in the center on the upper surface. The hot water inlet 20 leading to the valve seat 36 provided with the flow rate adjusting valve 22 with respect to the valve hole 37 is provided on one side, and the bathtub hot water inlet 19 on one side. A bathtub hot water outlet 21 is provided on the lower surface.
[0029]
Explaining the configuration of the flow rate control valve 22, the valve shaft 38 is fixedly attached to the lower end with a valve cylinder 39 for opening and closing the valve hole 37 of the valve seat 36, and bath water 2 that has flowed into the mixing chamber 35 inside. A thermostat 40, in which a wax 41 as a thermo element whose volume changes in accordance with the temperature of the hot water, is filled, and a piston 42 whose lower end abuts against the wax 41 is vertically movable, is fixedly fitted.
[0030]
Reference numeral 43 denotes a guide pipe extending above the mixing chamber 35 so that the valve shaft 38 of the flow rate adjusting valve 22 can be moved up and down, and 44 is fitted to the upper end of the guide pipe 39 to change the piston 42 according to the set temperature of the bath water. 45 is a plurality of pressing springs for pushing the flow rate adjusting valve 22 upward.
[0031]
A rotating shaft of a pulse motor 25 of the automatic hot water temperature setting device 23 is attached to a pressing shaft 44 which is a member for adjusting the operating range of the flow rate adjusting valve 22 by pressing the upper end of the piston 42 described above.
[0032]
As a result, the flow rate adjusting valve 22 is automatically driven by the pulse motor 25 controlled by the motor control device 26 in accordance with the hot water temperature set by the automatic hot water temperature setting device 23 with the hot water temperature setting key 24. The position is determined by moving up and down, and the operating range is adjusted according to the set hot water temperature.
[0033]
A valve cylinder 39 fixedly attached to the lower end of the valve shaft 38 of the flow rate adjusting valve 22 is as shown in FIG. 4, and the upper half is a closed water cylinder 46 that is a cylinder that closes the valve hole 37 of the valve seat 36. The lower half is a hot water supply cylinder 47 which is a cylinder provided with a plurality of notch grooves 48 as hot water supply grooves at a predetermined interval, and an attachment hole 49 for attaching to the valve shaft 38 is provided at the center. Yes.
[0034]
Therefore, in the flow rate adjusting valve 22, the valve cylinder 39 is attached to the lower end of the valve shaft 38 via the attachment hole 49, and then the valve cylinder 39 is inserted into the valve hole 37 of the valve seat 36 with respect to the mixing chamber 35. Is fitted to the guide tube 43 so as to be movable up and down, and is pushed upward by a plurality of pressing springs 45, and is deployed while pressing the upper end of the piston 42 from above with a pressing shaft 44.
[0035]
As a result, the flow rate adjusting valve 22 is pushed upward by opening the valve cylinder 39, and at the same time, the holding shaft 44 is positioned by the automatic hot water temperature setting device 23 in accordance with the set hot water temperature, so that the operating range is reduced. It is deployed in a regulated state.
[0036]
Using the hot water temperature regulator 18 configured as described above, the hot water of the bathtub hot water that is forced to circulate through the cleaning conduit 14 is heated with hot water produced by the chasing in the memorial device 27 to maintain an appropriate temperature. This will be described with reference to FIG.
[0037]
First, when the operation of the apparatus is started, the hot water temperature adjuster 18 is configured so that the flow rate adjusting valve 22 is pushed upward by the presser spring 45 and the valve cylinder 39 is moved as shown in FIG. 47 is located in the valve hole 36 of the mixing chamber 35 so that the valve opens, and the automatic hot water temperature setting device 23 adjusts the operating range of the flow rate adjustment valve 22 according to the temperature set by the hot water temperature setting key 24. It is in the setting state.
[0038]
When the operation of the apparatus is started in this state, the switching valves 15 and 16 are switched in the direction of the cleaning process, so that the hot water 2 in the bathtub 1 pumped up from the hot water suction pipe 3 by the circulation pump 6 is obtained. After being sterilized by the ultraviolet sterilizer 17, it is filtered by the filtration tank 5 and flows through the cleaning conduit 14.
[0039]
At this time, as described above, the hot water inlet 20 of the hot water temperature adjuster 18 is in a state in which the provided flow rate control valve 22 is opened and hot water can flow in. In the piping, a part of the bath water 2 flows from the hot water pipe 29 connected to the cleaning pipe 14, and in the piping of the second embodiment, the tap water flows from the incoming water pipe 34 connected to the water supply 33 and the combustion burner 31 is ignited. Hot water is made in memory.
[0040]
As a result, the bath water 2 that has flowed through the cleaning pipe enters the hot water temperature control device 18 from the bath water inlet 19, and at the same time, the hot water produced by the memorial device 27 passes through the hot water supply pipe 30 serving as a hot water supply pipe. Enter from the hot water inlet 20.
[0041]
Therefore, in the hot water temperature adjuster 18, hot water produced by the remedy device 27 is mixed with the bath water 2 that circulates in the cleaning pipe 14 in the mixing chamber 35 and enters the hot water temperature adjuster 18. The tub hot water outlet 21 returns to the cleaning conduit 14 and returns to the tub 1 from the fountain pipe 9.
[0042]
In this way, as shown in FIG. 5A, the flow rate control valve 22 for the hot water inlet 20 of the hot water temperature adjuster 18 is opened, and the hot water produced by the remedy device 23 is mixed and heated in the mixing chamber 31. Is continued, the temperature of the bathtub hot water 2 circulating through the cleaning conduit 14 and flowing into the hot water temperature regulator 18 continues to rise.
[0043]
Then, the flow rate adjusting valve 22 provided for the hot water inlet 20 of the hot water temperature adjuster 18 increases the temperature of the wax 41 which is the thermo element filled in the thermostat 40 and expands the volume to push the piston 42 upward. It becomes like this.
[0044]
However, since the upper end of the piston 42 is pressed by the holding shaft 44 at a position corresponding to the set temperature of the hot water, the flow rate adjusting valve 22 starts to move in the direction of closing the valve gradually downward, and the temperature of the bath water 2 is changed to the bather. Becomes the same as the set temperature, and the state as shown in FIG.
[0045]
That is, when the temperature of the bath water 2 increases and the volume of the wax 41 of the thermostat 40 continues to expand and decrease, the valve cylinder 39 fitted in the valve hole 37 of the valve seat 36 of the mixing chamber 35 continues to decrease, At the moment when the bath water 2 and the set temperature become the same, the lowering valve is closed until the lower end of the hot water closing tube 46 is just at the position of the valve hole 37, and hot water does not enter from the hot water inlet 20.
[0046]
Then, the bath water 2 from the hot water pipe 29 or the tap water from the hot water pipe 34 does not enter the memorial device 27, which is detected by the water flow sensor 32, and the combustion burner 31 is extinguished and no hot water is produced. The bathtub hot water 2 circulating in the cleaning conduit 14 is returned to the bathtub 1 as it is without being heated by being mixed with hot water in the hot water temperature regulator 18.
[0047]
(B) As shown in the figure, when the valve of the flow rate adjusting valve 22 with respect to the hot water inlet 20 of the hot water temperature adjuster 18 is closed and the bathtub hot water 2 is not heated and continues to circulate through the cleaning conduit 14, the temperature eventually decreases. put out.
[0048]
Then, since the volume of the wax 41 of the thermostat 40 starts to contract, the flow regulating valve 22 weakens the force pushing the piston 42 upward and rises upward, and the valve cylinder 39 has the hot water supply pipe 47 and the valve hole 37 of the valve seat 36. As shown in the figure, the bathtub hot water 2 circulating through the cleaning conduit 14 is mixed with hot water produced by the hot water regulator 18 in the remedy device 27. After being heated again, it returns to the bathtub 1.
[0049]
As described above, the hot water inlet 20 of the hot water temperature regulator 18 is used for the bathtub hot water 2 circulating through the cleaning conduit 14 while the hot water temperature is adjusted as described above. The valve of the flow rate control valve 22 provided for the valve is closed and does not become too high.
[0050]
In addition, since the operating range of the flow rate adjusting valve 22 is accurately adjusted by the automatic hot water temperature setting device 237 according to the set hot water temperature, the hot water is kept at the set temperature more accurately.
[0051]
That is, when the hot water temperature is set by manually turning the knob with the scale as a guide and the operating range of the flow rate control valve 22 is manually adjusted, the hot water temperature cannot be set very accurately.
[0052]
Then, even if the flow rate adjustment valve 22 opens and closes the valve accurately based on the temperature of the bath water, the set temperature cannot be set accurately, so the position of the pressing shaft 44 positioned according to the set temperature varies. Since the operating range is not precisely adjusted to the set temperature, the temperature of the bath water will vary considerably with respect to the temperature that the bather thinks is set.
[0053]
However, when the flow rate adjusting valve 22 adjusts the operating range by the automatic hot water temperature setting device 23, the bather can first set the hot water temperature accurately with the hot water temperature setting key 24, and then based on the accurately set hot water temperature. Since the holding shaft 44 is accurately positioned and the operating range is accurately adjusted, the bath water is accurately maintained at the set temperature.
[0054]
Furthermore, even if the bath water 2 is heated too much for some reason and becomes higher than the set temperature, as shown in (c), the flow rate control valve 22 for the hot water inlet 20 of the hot water temperature adjuster 18 is completely closed. The bath water 2 is in a state where the hot water is never mixed until the temperature drops below the set temperature and the temperature is never excessively high.
[0055]
That is, when the temperature of the bath water 2 becomes higher than the set temperature, the flow rate adjustment valve 22 of the hot water temperature regulator 18 continues to fall because the expansion of the wax 41 of the thermostat 40 continues, and eventually the valve hole of the valve seat 36 of the mixing chamber 35. 37 is closed by the upper end of the hot water closing cylinder 46 of the valve cylinder 39, and the valve is completely closed.
[0056]
When this happens, the bath water 2 continues to circulate through the cleaning line 14 without being heated, and the temperature gradually decreases. The flow rate control valve 22 of the hot water temperature regulator 18 contracts the wax 41 of the thermostat 40 and the piston 42 The force that pushes upward weakens and gradually rises, eventually becomes the same as the set temperature (b), passes through the state shown in the figure, drops below the set temperature, and (a) the valve again as shown in the figure Until hot water is opened, the hot water produced by the memorial device 27 is never heated.
[0057]
As described above, the hot water temperature adjuster 18 mixes hot water produced by the remedy device 27 by closing the flow rate adjusting valve 22 provided for the hot water inlet 20 at the same time as the temperature of the bath water becomes the same as the set temperature. Therefore, the bath water 2 is always at or below the set temperature, and is hardly raised too much.
[0058]
Even if the bath water 2 becomes higher than the set temperature, the flow control valve 22 moves in a direction to close the valve firmly as the temperature of the bath water 2 rises, and never opens the valve until the temperature drops below the set temperature. During this time, the hot water will be mixed with more hot water so that there is no danger of burns.
[0059]
Moreover, the hot water temperature regulator 18 is provided in the state which provided the flow control valve 22 with respect to the hot water inflow port 20 in the middle of the purification pipe line 14 of the bathtub hot water 2, and the low temperature bathtub hot water 2 always flows in, Only when the temperature of the bath water 2 falls below the set temperature, the valve is opened and the hot water produced by the memory device 27 is mixed to adjust the temperature of the bath water 2, so that the valve malfunctions. Even if hot water does not spout into the bathtub 1, it is safe.
[0060]
That is, when the flow rate control valve 22 fails and the valve remains closed, the hot water 2 is mixed with the hot water made by the remedy device 27 and is not heated and spouts into the bathtub 1 in a state lower than the set temperature. There is no danger just by continuing, even if the valve remains open, it will always be in a state where the low temperature bath water 2 and hot water are mixed, so even if it becomes too hot, it will never burn you There is no danger that only hot water produced by the remedy device 27 will be ejected into the bathtub 1 and burned, only the bathtub hot water 2 having a temperature at which there is no danger is ejected into the bathtub 1.
[0061]
If the flow rate adjusting valve 22 provided for the hot water inlet 20 of the hot water temperature regulator 18 is a thermostat type, the valve opens and closes depending on the temperature of the bath water 2 and is simply turned on at a predetermined temperature. Much more precise temperature control is possible than with a solenoid valve that simply turns off.
[0062]
The flow control valve 22 may be configured to simply open and close the valve hole 37 with a valve plate. However, as shown in the embodiment, a valve cylinder 39 divided into a hot water supply pipe 46 and a hot water supply pipe 47 is divided into valve holes. If it is configured to be freely movable up and down on 37, the opening and closing of the valve becomes more precise and the temperature can be adjusted accurately.
[0063]
That is, when the temperature of the bath water 2 is too lower than the set temperature, the flow rate adjusting valve 22 is configured so that the hot water supply tube 47 provided with the notch groove 48 serving as the hot water supply groove exits on the valve seat 36 and opens the valve. However, the length of the hot water supply pipe 47 that goes over the valve seat 36, that is, the amount of opening of the valve, which is the hot water supply area, changes according to the temperature of the bathtub hot water 2.
[0064]
For this reason, the hot water temperature adjuster 18 has an amount proportional to the temperature difference between the set temperature and the bath water 2 when the bath water 2 is heated below the set temperature and the flow rate control valve 22 is opened. Hot water is made by the reheating device 27 and enters from the hot water inlet 20 to heat the bathtub hot water 2 quickly and accurately to the set hot water temperature.
[0065]
Moreover, since the valve is closed and hot water does not enter the mixing chamber 35 at the moment when the bath water 2 reaches the set temperature, the bath water 2 hardly reaches the set temperature.
[0066]
On the other hand, when the temperature of the bath water becomes higher than the set temperature and the flow rate control valve 22 is closed, the length of the hot-water pipe 46 that exits under the valve seat 37, that is, the amount of closing the valve, is also the same If the bath water 2 is too higher than the set temperature, the valve will be completely closed as it is too high and never open until the bath water 2 falls below the set temperature. While accurately adjusting the temperature, the bath water 2 is completely prevented from becoming too hot.
[0067]
In addition, as a flow control valve provided with respect to the hot water inlet 20 of the hot water temperature regulator 18, a thermostat type as shown in the above-mentioned embodiment is preferable, but depending on the temperature of the bath water such as a bimetal type or a shape memory alloy type. Needless to say, other types of valves may be used if the valves can be opened and closed automatically.
[0068]
Further, in the thermostat type flow control valve, a material that changes in volume greatly in response to heat, such as a gas or a low melting point alloy other than wax, may be used as the thermo element.
[0069]
【The invention's effect】
The present invention is configured as described above, and the hot water temperature regulator 18 provided in the middle of the cleaning pipe 14 mixes and heats an appropriate amount of hot water made of the bath water 2 by the memory device 27 according to the hot water temperature. Then, the temperature is accurately adjusted in a safe state where hot water does not directly spout into the bathtub 1.
[0070]
In addition, an automatic hot water temperature setting device 23 is provided in the flow rate adjusting valve 22 provided in the hot water temperature controller 18, and the temperature of the bath water 2 is adjusted more precisely to the temperature set by the bather.
[0071]
