Description

【0001】
【産業上の利用分野】
本発明は浴槽湯の清浄化装置に係り、特にこの装置におけるれ湯の温度の調節装置に関するものである。
【0002】
【従来技術】
浴槽内の湯を循環ポンプを利用して強制的に循環させ、循環路に配備された濾過装置で湯中の汚れを取り除いた後、活性石タンクで活性化するような浴槽湯の清浄化装置が従来より開発されていた。
【0003】
さらに最近は、単に湯中の汚れを取り除いたり活性化するだけでなく、殺菌も行って湯を一層清浄にすると同時に、湯を加熱して常に適温を保ち、24時間いつでも好みの時間に入浴できるようにした図6に示すような装置が広く利用されるようになった。
【0004】
この装置では、浴槽1内の湯2を循環ポンプ6の作用で先端にプレフイルター10が取り付けられた吸湯管3から各種清浄化処理機器をまとめて収納した装置本体4に吸い上げて清浄化処理をし、清浄化処理の終わった湯は先端にジエツトノズル11が取り付けられた噴湯管9から再び浴槽1内に噴出させるように構成している。
【0005】
装置本体4には、活性炭、麦飯石、ゼオライト等の各種粒状濾材が充填される濾過タンク5、湯を強制循環するための循環ポンプ6、湯を適温に保持する保温用のヒータ7等が連結管で直列に連結しされて配備され、前記吸湯管3の一端が濾過タンク5の入湯口に、噴湯管9の一端が循環ポンプ7の吐出口にそれぞれ接続して浴槽1内の湯2に対する直列の清浄化管路を形成している。
【0006】
噴湯管9の先端に取り付けられたジエツトノズル11には湯の流速を速めて形成した負圧を利用して吸気し湯中に空気を混入するためのエジエクタ部が設けられ、このエジエクタ部には吸気口に電磁弁13を設けた吸気管12が接続し、さらに吸気管12には吸い込まれた空気をオゾン化するためのオゾナイザ8が取り付けられている。
【0007】
前記装置では、浴槽1内の湯2は、循環ポンプ6の作動によりプレフイルター10で大きな汚れを取り除かれつつ吸湯管3から吸い上げられて装置本体4に入り、先ず濾過タンク5で濾過され、続いてヒータ7で保温された後、噴湯管9の先端に取り付けられたジエツトノズルから浴槽1に再び噴出される。
【0008】
この際、吸気管12には、吸気口部に設けた電磁弁13が開いていると空気が吸い込まれ、ジエツトノズル11からは空気が混入したジエツト流が浴槽1内に噴出されいわゆる泡風呂となり、さらにオゾナイザ8が作動していると吸い込まれた空気がオゾン化され、浴槽1内の湯2がオゾン殺菌される。
【0009】
【発明が解決しようとする課題】
しかしながら、従来の装置では湯を適温に保つための電気ヒータにより加熱が行われており、これは24時間続けられているので電気代がかなりかかる。
【0010】
最近電力会社は発電量の平準化のため、午後11時から午前7時までの深夜電力の利用の促進を図るため、深夜料金を安くし代わりに昼間の料金を割高にするような料金契約もできるようにしている。
【0011】
したがってこのような料金契約をすると、深夜電力の料金は昼間電力料金の3割程度となるので、浴槽湯清浄化装置における深夜の加熱は割安な深夜電力料金で行えることとなるが、昼間も加熱しているので逆に昼間の加熱は割高な昼間電力料金で行わなければならないので、全体の電気代は決して安くならない。
【0012】
本発明は、前記したような従来技術の欠点を解消し、深夜電力料金その他の経済的なエネルギーを利用して浴槽湯の加熱を行い、加熱にかかる代金の安い浴槽湯清浄化方法及び装置を提供することを目的とする。
【0013】
【課題を解決するための手段】
すなわち、本発明は、浴槽内の湯を吸湯管から汲み上げて清浄化管路を循環させて清浄化し、噴湯管から浴槽に戻す浴槽湯清浄化装置において、高温の蓄熱湯を貯え、底面の浴槽湯流入口に浴槽湯流出管を接続し、上部の蓄熱湯流出口に蓄熱湯流出管を接続した蓄熱タンクを配備し、浴槽湯流出管は、循環する湯の温度を感知して自動的に弁が所定の開度となるように作動し、湯の流出量を湯温に応じて自動的に調節する浴槽湯流出量の自動調節手段を介して清浄化管路に接続し、蓄熱湯流出管は、湯温センサが検知した湯温に応じて開閉が制御される遮断弁を配備して清浄化管路に接続し、湯温が設定温度以下になったのを湯温センサが検知すると、前記遮断弁を開くよう制御し、自動的に湯温に応じた開度となっている浴槽湯流出量の自動調節手段の調節により湯温に応じた量の浴槽湯を清浄化管路から浴槽湯流出管に流出させて蓄熱タンクに流入させ、流入した浴槽湯と同じ量の蓄熱湯を蓄熱タンクから蓄熱湯流出管に流出させて清浄化管路に流入させ、湯温に応じた量の熱湯を清浄化管路を流通する浴槽湯に混入して湯温を調節するよう構成する。
【0014】
これにより、高価で複雑な制御を必要とする流量調整弁を利用せず、自動開閉式オリフィスのような、低コストで、正確に湯の流出量を湯温に応じて自動的に調節できる浴槽湯流出量の自動調節手段と、単に開閉を制御するだけの遮断弁との組合わせで、迅速で、精密な湯温の調節が可能となる。
【0015】
また、好ましくは、前記構成において、蓄熱タンクの蓄熱湯流出口に接続する蓄熱湯流出管に、蓄熱タンクから流出する蓄熱湯の温度を感知して自動的に弁が所定の開度となるように作動し、蓄熱湯の流出量を自動的に制限する蓄熱湯流出量の自動制限手段を配備し、湯温の低下の度合いが大きく、多量の浴槽湯が蓄熱タンクに流入した際に、蓄熱タンクから高温の蓄熱湯が多量に流出するのを防ぐことを可能にしたことを特徴とする請求項1記載の浴槽湯清浄化装置。
【0016】
これにより、湯温の低下の度合いが大きいために、浴槽湯流出量の調節手段の開度が大きくなり、多量の浴槽湯が蓄熱タンクに流入し、流入した浴槽湯の量に応じて多量の蓄熱湯が蓄熱タンクから蓄熱湯流出管に流出する状態になったても、自動開閉式オリフィスのような低コストの蓄熱湯流出量の制限手段によって多量の蓄熱湯が浴槽に一気に流出するのを防ぎ、入浴者の安全を保つようにできる。
【0017】
【発明の作用】
本発明は前記したように構成され、蓄熱タンクに溜めておく蓄熱湯を深夜電力、太陽熱その他の代金の安いエネルギーで加熱して高温に保っておき、この高温の蓄熱湯と温度の下がった浴槽湯とを浴槽湯の温度の下がり具合に応じて所定量づつ入れ替えれば、浴槽湯は所定の温度に絶えず調節されており、しかもこの温度調節にかかる加熱費は安くなる。
【0018】
前記したような浴槽湯の温度調節方法は、深夜電力、太陽熱その他低コストエネルギーでの加熱装置を持つ高温の蓄熱湯を溜める蓄熱タンクをまず配備し、この蓄熱タンクと清浄化装置本体の清浄化管路とを湯温調節管路で接続した装置を構成すれば、温度の下がった浴槽湯は湯の温度にに応じて高温の蓄熱湯と所定量容易に入れ替えられ安い加熱費で温度調節される。
【0019】
さらに湯温調節管路を、噴湯管に配備した浴槽湯流出量調節弁と、該浴槽湯流出量調節弁上流部と蓄熱タンク底面の浴槽湯流入口とを接続する浴槽湯流出管と、蓄熱タンク上部側面の蓄熱湯流出口と噴湯管に配備した浴槽湯流出量調節弁の下流部とを接続し蓄熱湯流出量調節弁と蓄熱湯遮断弁とを噴湯管方向に順次配備した蓄熱湯流出管と、浴槽湯流出管と蓄熱湯流出管の蓄熱湯遮断弁下流部とを接続する浴槽湯還流管とから成るよう構成すると、まず浴槽湯の温度に応じて蓄熱湯の遮断弁を開くと同時に浴槽湯を蓄熱タンクに流出させ同量の高温の蓄熱湯と入れ替えての温度調節が極めて簡便な構成の装置で容易にできる。
【0020】
しかもこの湯温調節管路には蓄熱湯流出管に流量調節弁を設けてあるので、蓄熱湯の温度に応じて蓄熱湯の流出量を調節し、浴槽湯の温度が大幅に低下している場合でも浴槽湯と高温の蓄熱湯とを多量に一気に入れ替えて浴槽に高温の湯が多量に噴出しまうようなことはない。
【0021】
さらに浴槽湯及び/又は蓄熱湯の流出量調節弁が、湯温に応じて邪魔板が変形し弁の開度を変化させるバイメタル式オリフイスとするか、或いは設定温度での弁の開度を形状記憶合金製邪魔板に記憶させた形状記憶合金式オリフイスとすると、故障の少ない簡便な弁構造でしかも複雑な制御を行わなくても、容易に浴槽湯の温度に応じて浴槽湯並びに蓄熱湯の流出量を調節し湯温の調節ができる。
【0022】
【実施例】
本発明の基本的な構成を図1の基本ブロツク図によりまず説明する。
【0023】
図1において先に説明した従来例と同一の構成部品には同一の符号が付してあるのでこれらの従来例と同一の構成についての説明は省略し、従来例とは異なる構成の部分についてのみ説明する。
【0024】
14が濾過装置5等の清浄化処理機器が直列に配備された浴槽湯の清浄化管路であり、15は清浄化管路14の適宜の位置に循環する浴槽湯2の温度を検知するために配備された湯温センサであり、16は噴湯管9の途中に配備された浴槽湯流出量調節弁である。
【0025】
浴槽湯流出量調節弁16は、清浄化管路14で清浄化の終わった浴槽湯2を温度に応じては浴槽1へ総て噴出させないで一部を温度調節のために後述する蓄熱タンク方向へ流出させるため、浴槽湯2の蓄熱タンク方向への流出量を調節するための装置として配備されている。
【0026】
この浴槽湯流出量調節弁16の浴槽湯温度と弁の開度との関係は図2(a)に示す通りであり、浴槽湯2の温度が低いほど弁の開度を小さくし、浴槽湯2が浴槽湯流出量調節弁16を経て噴湯管9から直接浴槽1に噴出する量を少なくし、高温の湯が溜められた蓄熱タンク方向へ向かう量を多くし、多量の浴槽湯2を高温の湯と入れ替えて温度が短時間で所定の温度に調節できるようにする。
【0027】
17が高温の湯である蓄熱湯18を溜めて置くための蓄熱タンクであり、この蓄熱湯18を深夜電力で加熱するためのヒータ19が配備されている。
【0028】
勿論蓄熱タンク17に溜める蓄熱湯18の加熱には、太陽エネルギーや化学エネルギー等の深夜電力以外の安いエネルギーを利用するようにしても良い。
【0029】
蓄熱タンク17には、温度調節のために浴槽湯2と蓄熱湯18とを所定量づつ入れ替えるため、底面には温度調節用の浴槽湯2を流入させるための浴槽湯流入口20が設けられ、側面上部には蓄熱湯18を流出するための蓄熱湯流出口21が設けられている。
【0030】
次に前記蓄熱タンク17と清浄化管路14とを接続する湯温調節管路22の構成について説明すると、23は浴槽湯流出管であり、この浴槽湯流出管23は一端が蓄熱タンク17の底面の浴槽湯流入口20に接続し、他の一端は噴湯管9の浴槽湯流出量調節弁16の上流部に接続している。
【0031】
24は蓄熱湯流出管であり、この蓄熱湯流出管24の一端は蓄熱タンク17の蓄熱湯流出口21に接続し、他の一端は噴湯管9の浴槽湯流出量調節弁16の下流部に接続し、管路の途中には蓄熱湯流出量調節弁25及び蓄熱湯遮断弁26が噴湯管9方向に向かって順次配備されている。
【0032】
蓄熱湯流出量調節弁25は蓄熱タンク17の蓄熱湯18が一度に多量に流出し浴槽1内に高温の湯が噴出するのを防ぐため蓄熱湯18の湯温に応じて流出量を調節するための装置として配備されている。
【0033】
蓄熱タンク17の蓄熱湯18の温度と蓄熱湯流出量調節弁25の弁の開度との関係は図2(b)に示す通りであり、蓄熱湯18の温度が高いほど蓄熱湯流出量調節弁25の弁の開度を小さくして高温の湯が多量に流出しないようにしている。
【0034】
蓄熱湯遮断弁26は、蓄熱湯流出管24の管路は清浄化管路を循環する浴槽湯2の温度が下がり湯温の調節が必要になった場合に限って開くよう、清浄化管路14に配備された湯温センサ15が検知した浴槽湯2の温度に基づいて制御装置27が蓄熱湯流出管24の管路を開閉するために配備した装置である。
【0035】
噴湯管9に配備される浴槽湯流出量調節弁16や蓄熱湯流出管24に配備される蓄熱湯流出量調節弁25としては様々な弁の構造が考えられ、これらの弁の開度を湯温に応じてマイクロコンピユータを利用した制御装置により制御して流出量を調節しても良いが、図3に示すような、邪魔板をバイメタルとするか形状記憶合金とするオリフイス流量調節弁を利用すると、構造が簡単でしかも比較的正確に湯温に応じた流量調節ができ好都合である。
【0036】
このオリフイス流量調節弁ではオリフイス管28の管径を邪魔板29を例えば湯温度に応じて1点鎖線の状態から実線の状態に変えて流量を調節するが、邪魔板29をバイメタル製として湯温に応じて変形させて管径を連続的に変化させ流量を調節するか、或いは邪魔板29を形状記憶合金製として設定された温度で記憶した形状として管径を変えて流量を調節するかする。
【0037】
このオリフイス流量調節弁を浴槽湯流出量調節弁16として用いる場合は、弁の開度は、浴槽湯2の温度が40℃の時には100%に、30℃の時には50%になるよう調節してある。
【0038】
またオリフイス流量調節弁を蓄熱湯流出量調節弁25として利用する場合には、弁の開度は、蓄熱湯18の温度が85℃の時には30%に、50℃の時には100%になるよう調節してある。
【0039】
さらに噴湯管9及び蓄熱湯流出管24の直径は、浴槽湯流出量調節弁16の弁の開度が50%、蓄熱湯流出量調節弁25の弁の開度が50%の時に、噴湯管9に流れる浴槽湯2の量と蓄熱湯流出管24に流れる蓄熱湯18の量の比が2対1となるように設計しておく。
【0040】
このような設計とすると、浴槽湯2の温度が30℃の場合でも30分程度の温度調節により入浴温度の40℃にでき、また浴槽1に噴出する浴槽湯2と蓄熱湯18とが混合された湯の温度を46℃以下に押さえられる。
【0041】
次に図4及び図5の配管図に基づいて浴槽湯を清浄化処理する際の湯の循環路について説明するが、ここでは清浄化処理機器として濾過装置5のみが示されオゾン殺菌その他の機器については省略してある。
【0042】
図4には清浄化管路14を循環する浴槽湯2の温度が所定の入浴温度であると湯温センサ15が検知し、特に湯温調節を必要としない場合の湯の循環路が矢印で示されている。
【0043】
この場合には、湯温センサ15の検知結果に基づいて制御装置27は蓄熱湯流出管24に配備された蓄熱湯遮断弁26を閉じ、湯温調節管路22には浴槽湯2、蓄熱湯18共に全く流れない状態となる。
【0044】
したがって循環ポンプ6の作動によって吸湯管3から吸い上げられた浴槽湯2が清浄化管路14のみを流れ、濾過装置5で濾過された後100%開いた浴槽湯流出量調節弁16を経て噴湯管から浴槽1に再び噴出される循環のみが行われる。
【0045】
図5には清浄化管路14を循環する浴槽湯2の温度が所定の入浴温度以下に下がったことを湯温センサ15が検知し、湯温調節が必要である場合の湯の循環路が矢印で示されている。
【0046】
この場合には、湯温センサ15の検知結果に基づいて制御装置27は蓄熱湯流出管24に配備された蓄熱湯遮断弁26を開き、噴湯管9に配備された浴槽湯流出量調節弁16及び蓄熱湯流出量調節弁25は前記したような弁の設計に基づいて浴槽湯2及び蓄熱湯18の温度に応じた開度となり、湯温調節管路22に湯が流れて湯温調節が行われる状態となる。
【0047】
すなわち清浄化管路14を循環する浴槽湯2は、濾過装置5での濾過が終わった後浴槽湯流出量調節弁16が湯温に応じた開度となっているのでこの浴槽湯流出量調節弁16の開度に従って噴湯管9方向と浴槽湯流出管23方向と分かれて流れる。
【0048】
噴湯管9方向に向かった浴槽湯2は、勿論そのまま浴槽1に噴出され、一方浴槽湯流出管23方向に向かった浴槽湯2は、蓄熱タンク17に底面の浴槽湯流入口20から流入する。
【0049】
この結果、蓄熱タンク17に溜められていた蓄熱湯18は流入した浴槽湯2に押されて蓄熱湯流出口21から蓄熱湯流出管24に流出し、蓄熱湯の温度に応じた開度になっている蓄熱湯流出量調節弁25及び開いている蓄熱湯遮断弁26を経て噴湯管9の中に流入し、浴槽湯2に混入して浴槽1に噴出する。
【0050】
このようにして温度の下がった浴槽湯2がその温度の下がり具合に比例した量だけ高温の蓄熱湯18と入れ替わる湯温調節管路22を利用しての湯温の調節が浴槽湯2の温度が所定の入浴温度になったと湯温センサ15が検知するまで続けられる。
【0051】
前記したような湯温調節管路22を利用しての湯温の調節において、浴槽湯2の温度が大幅に低下した場合には、浴槽湯流出量調節弁16の開度は温度に比例するよう調節されているので浴槽湯流出管23に多量の湯が流出するようになり、これにより蓄熱タンク17の蓄熱湯18も本来は多量に蓄熱湯流出管24に流出することになる。
【0052】
しかしながら蓄熱湯流出管24には蓄熱湯18の温度に反比例した流出量となるよう開度が調節された蓄熱湯流出量調節弁25が配備されているので、蓄熱湯18の温度が高いときには蓄熱湯18の流出量が制限される。
【0053】
この結果、温度が低いために多量に蓄熱湯流出管24に流出してきた浴槽湯2は蓄熱湯18の温度が高い場合には蓄熱タンク17へ全ては流入できないで、残りは噴湯管9へと還流し、浴槽湯2が一度に多量の高温の蓄熱湯18と入れ替わることにより多量の高温の湯が噴湯管9から浴槽1に噴出するのを防いでいる。
【0054】
【発明の効果】
本発明は以上のような構成及び作用のものであり、極めて経済的に24時間浴槽湯を適温に保てる浴槽湯清浄化方法を提供すると同時にこの方法を実現した簡便な浴槽湯清浄化装置を提供する。
【0055】
これにより24時間何時でも清浄でしかも適温になっている風呂を経済的な状態で楽しめるようになる。

[Industrial application fields]
The present invention relates to a bath water cleaning device, and more particularly to a temperature adjusting device for the hot water in this device.
[0002]
[Prior art]
Hot water in the bathtub is circulated forcibly using a circulation pump, and the hot water in the bathtub is activated by an active stone tank after removing the dirt in the hot water with a filter installed in the circulation path. Has been developed in the past.
[0003]
More recently, it not only removes and activates the dirt in the hot water, but also sterilizes it to make the hot water even cleaner, and at the same time heats the hot water to keep it at an appropriate temperature, so you can take a bath at any time you want for 24 hours. Such a device as shown in FIG. 6 has been widely used.
[0004]
In this apparatus, the hot water 2 in the bathtub 1 is sucked up by the action of the circulation pump 6 from the hot water suction pipe 3 having the prefilter 10 attached to the tip thereof to the apparatus main body 4 that collectively accommodates various cleaning processing equipment. Then, the hot water after the cleaning process is configured to be ejected again into the bathtub 1 from a fountain pipe 9 having a jet nozzle 11 attached to the tip.
[0005]
Connected to the apparatus body 4 are a filtration tank 5 filled with various particulate filter media such as activated carbon, barley stone, and zeolite, a circulation pump 6 for forcibly circulating hot water, a heater 7 for keeping warm at an appropriate temperature, and the like. The hot water in the bathtub 1 is connected by connecting one end of the hot water pipe 3 in series with a pipe, and one end of the hot water pipe 3 is connected to the hot water inlet of the filtration tank 5 and one end of the hot water pipe 9 is connected to the outlet of the circulation pump 7. Is formed in series with the cleaning line.
[0006]
The jet nozzle 11 attached to the tip of the fountain pipe 9 is provided with an ejector section for taking in air by using the negative pressure formed by increasing the flow velocity of the hot water and mixing air into the hot water. An intake pipe 12 provided with a solenoid valve 13 is connected to the mouth, and an ozonizer 8 is attached to the intake pipe 12 for ozonizing the sucked air.
[0007]
In the apparatus, the hot water 2 in the bathtub 1 is sucked up from the hot water suction pipe 3 while removing large dirt by the prefilter 10 by the operation of the circulation pump 6 and enters the apparatus main body 4, and is first filtered by the filtration tank 5, Subsequently, after being kept warm by the heater 7, it is ejected again from the jet nozzle attached to the tip of the fountain pipe 9 into the bathtub 1.
[0008]
At this time, air is sucked into the intake pipe 12 when the electromagnetic valve 13 provided at the intake port is opened, and a jet stream mixed with air is jetted into the bathtub 1 from the jet nozzle 11 to form a so-called bubble bath. Further, when the ozonizer 8 is operating, the sucked air is ozonized, and the hot water 2 in the bathtub 1 is sterilized with ozone.
[0009]
[Problems to be solved by the invention]
However, in the conventional apparatus, heating is performed by an electric heater for keeping hot water at an appropriate temperature, and since this is continued for 24 hours, the electricity cost is considerably high.
[0010]
Recently, the electric power company has also made a rate contract to lower the midnight fee and increase the daytime fee instead to promote the use of late-night electricity from 11:00 pm to 7:00 am to level the amount of power generation I can do it.
[0011]
Therefore, if such a price contract is made, the midnight electricity charge will be about 30% of the daytime electricity charge, so the midnight hot water heating in the bathtub hot water purifier can be done at a cheaper midnight electricity charge, but also during the daytime. On the contrary, daytime heating must be done at a high daytime electricity rate, so the total electricity bill will never be cheap.
[0012]
The present invention eliminates the drawbacks of the prior art as described above, heats bath water using midnight power charges and other economical energy, and provides a bath water cleaning method and apparatus for cheap heating costs. The purpose is to provide.
[0013]
[Means for Solving the Problems]
That is, the present invention is a bathtub hot water purifier that draws hot water in a bathtub from a hot water pipe, circulates and purifies the cleaning pipe, and returns the hot water from the fountain pipe to the bathtub. A hot water storage tank with a hot water outlet pipe connected to the hot water outlet and a hot water outlet pipe connected to the upper hot water outlet is installed. The hot water outlet pipe automatically detects the temperature of the circulating hot water. The hot water storage hot water is connected to the cleaning pipe via an automatic adjustment means for the bath water outflow amount, which automatically adjusts the outflow amount of hot water according to the hot water temperature. For the outflow pipe, a shut-off valve that is controlled to open and close according to the hot water temperature detected by the hot water temperature sensor is installed and connected to the cleaning pipe, and the hot water temperature sensor detects that the hot water temperature has fallen below the set temperature. Then, control is performed to open the shutoff valve, and the amount of bath water outflow automatically adjusted to the hot water temperature. By adjusting the adjustment means, an amount of bath water corresponding to the hot water temperature is caused to flow from the cleaning pipe to the bathtub hot water outlet pipe and flow into the heat storage tank, and the same amount of hot water as the inflowed bath water is stored from the heat storage tank. It is configured to flow into the outflow pipe and flow into the cleaning pipe, and to adjust the hot water temperature by mixing hot water in an amount corresponding to the hot water temperature into the bath water flowing through the cleaning pipe.
[0014]
This makes it possible to automatically adjust the outflow amount of hot water according to the hot water temperature accurately at a low cost, such as an automatic opening / closing orifice, without using a flow control valve that requires expensive and complicated control. The combination of the automatic adjustment means for the amount of hot water outflow and the shut-off valve that simply controls the opening and closing enables quick and precise adjustment of the hot water temperature.
[0015]
Preferably, in the above configuration, the valve is automatically set to a predetermined opening degree by sensing the temperature of the hot water flowing out from the heat storage tank in the hot water outlet pipe connected to the hot water outlet of the heat storage tank. The automatic storage means for limiting the outflow amount of hot water is automatically installed, and when the amount of hot water drops is large and a large amount of bath water flows into the heat storage tank, 2. The bath water purifier according to claim 1, wherein a large amount of high-temperature hot water is prevented from flowing out of the tank.
[0016]
Thereby, since the degree of decrease in the hot water temperature is large, the opening degree of the bath water outflow adjustment means is increased, and a large amount of the bath water flows into the heat storage tank. Even when the hot water has flowed out of the hot water storage tank to the hot water outlet pipe, a large amount of hot water will flow into the bathtub at once by the low-cost storage hot water outflow limiting means such as an automatic open / close orifice. To prevent and keep the bather safe.
[0017]
[Effects of the Invention]
The present invention is constructed as described above, and heat storage hot water stored in the heat storage tank is heated by midnight power, solar heat and other cheap energy, and kept at a high temperature. If the hot water and the hot water are replaced by a predetermined amount according to the temperature drop of the bath water, the hot water is constantly adjusted to the predetermined temperature, and the heating cost for the temperature adjustment is reduced.
[0018]
The temperature control method for bath water as described above is to first arrange a heat storage tank for storing high-temperature heat storage water having a heating device with midnight power, solar heat or other low-cost energy, and cleaning the heat storage tank and the cleaning device main body. If you configure a device that connects the pipe with a hot water temperature control pipe, the bath water that has fallen in temperature can be easily replaced with hot stored hot water by a predetermined amount according to the temperature of the hot water, and the temperature can be adjusted at a low heating cost. The
[0019]
Furthermore, a hot water temperature adjustment pipe is provided in the fountain pipe, the bathtub hot water outflow control valve, the bath hot water outflow pipe connecting the upstream portion of the bathtub hot water outflow control valve and the bathtub hot water inlet at the bottom of the heat storage tank, and the heat storage Heat storage hot water outflow that connects the hot water outlet of the tank on the upper side of the tank and the downstream part of the bathtub hot water outflow control valve arranged in the fountain pipe, and sequentially arranges the hot water outflow control valve and the hot water shutoff valve in the direction of the fountain pipe When it is configured to comprise a bathtub and a bathtub hot water recirculation pipe that connects the bathtub hot water outflow pipe and the heat storage hot water shutoff valve downstream portion of the hot water storage outflow pipe, first, when the heat storage hot water shutoff valve is opened according to the temperature of the bath water At the same time, it is possible to easily adjust the temperature by flowing out the bathtub water into the heat storage tank and replacing it with the same amount of high-temperature heat storage water with an apparatus having a very simple configuration.
[0020]
Moreover, since the hot water temperature control pipe is provided with a flow control valve in the hot water storage outflow pipe, the amount of the hot water stored in the hot water is adjusted according to the temperature of the hot water, and the temperature of the hot water in the bath is greatly reduced. Even in such a case, there is no case where a large amount of hot water is jetted into the bathtub by changing a large amount of hot water and hot water storage hot water.
[0021]
In addition, the bath water and / or hot water storage flow rate control valve is a bimetallic orifice that changes the opening of the baffle plate according to the hot water temperature, or the valve opening at the set temperature With the shape memory alloy orifices memorized in the memory alloy baffle plate, it is possible to easily adjust the bath water and regenerative hot water according to the temperature of the bath water without complicated control with a simple valve structure with few failures. Adjust the outflow amount and adjust the hot water temperature.
[0022]
【Example】
The basic configuration of the present invention will be described first with reference to the basic block diagram of FIG.
[0023]
In FIG. 1, the same components as those of the conventional example described above are denoted by the same reference numerals, so that the description of the same configuration as those of the conventional example is omitted, and only the parts having a different configuration from the conventional example are described. explain.
[0024]
Reference numeral 14 denotes a bathtub hot water cleaning pipe in which cleaning devices such as the filtration device 5 are arranged in series, and 15 denotes a temperature of the bathtub hot water 2 circulating to an appropriate position of the cleaning pipe 14. A hot water temperature sensor 16 is provided, and 16 is a bathtub hot water outflow control valve provided in the middle of the fountain pipe 9.
[0025]
The bathtub hot water outflow control valve 16 is directed to a heat storage tank, which will be described later for temperature control, without jetting the bathtub hot water 2 that has been cleaned in the cleaning pipe 14 to the bathtub 1 in accordance with the temperature. Therefore, it is deployed as a device for adjusting the amount of outflow of the bathtub hot water 2 toward the heat storage tank.
[0026]
The relationship between the bath water temperature of the bath water outflow control valve 16 and the opening of the valve is as shown in FIG. 2 (a). The lower the temperature of the bath water 2, the smaller the opening of the valve. 2 decreases the amount of water jetted directly from the fountain pipe 9 to the bathtub 1 via the bathtub hot water outflow control valve 16, increases the amount directed toward the heat storage tank where hot water is accumulated, So that the temperature can be adjusted to a predetermined temperature in a short time.
[0027]
Reference numeral 17 denotes a heat storage tank for accumulating hot storage water 18 which is hot water, and a heater 19 for heating the heat storage water 18 with midnight power is provided.
[0028]
Of course, cheap energy other than late-night power such as solar energy or chemical energy may be used for heating the hot water 18 stored in the heat storage tank 17.
[0029]
The heat storage tank 17 is provided with a bath water inlet 20 for allowing the temperature adjusting bath water 2 to flow in, so that the bath water 2 and the heat storage water 18 are exchanged by a predetermined amount for temperature adjustment. A heat storage hot water outlet 21 for flowing out the heat storage hot water 18 is provided on the upper side surface.
[0030]
Next, the structure of the hot water temperature adjusting pipe 22 connecting the heat storage tank 17 and the cleaning pipe 14 will be described. 23 is a bathtub hot water outflow pipe, and one end of the bathtub hot water outflow pipe 23 is connected to the heat storage tank 17. It is connected to the bathtub hot water inlet 20 on the bottom surface, and the other end is connected to the upstream portion of the bathtub hot water outflow regulating valve 16 of the fountain pipe 9.
[0031]
Reference numeral 24 denotes a hot water outlet pipe, and one end of the hot water outlet pipe 24 is connected to the hot water outlet 21 of the heat storage tank 17, and the other end is connected to the downstream portion of the bathtub hot water outlet control valve 16 of the hot water pipe 9. In the middle of the pipe line, a stored hot water outflow adjustment valve 25 and a stored hot water shutoff valve 26 are sequentially arranged toward the fountain pipe 9.
[0032]
The stored water hot water outflow adjustment valve 25 adjusts the amount of outflow according to the hot water temperature of the hot water storage 18 in order to prevent the hot water 18 in the heat storage tank 17 from flowing out in large quantities at once and hot water from being ejected into the bathtub 1. It is deployed as a device for.
[0033]
The relationship between the temperature of the hot water 18 in the heat storage tank 17 and the opening degree of the hot water outlet control valve 25 is as shown in FIG. 2 (b). The opening degree of the valve 25 is reduced so that a large amount of hot water does not flow out.
[0034]
The regenerator hot water shut-off valve 26 is arranged so that the pipe of the regenerator hot water outflow pipe 24 is opened only when the temperature of the bathtub hot water 2 circulating in the clean pipe decreases and the hot water temperature needs to be adjusted. 14 is a device provided for the controller 27 to open and close the conduit of the hot water outlet pipe 24 based on the temperature of the bathtub hot water 2 detected by the hot water temperature sensor 15 provided in FIG.
[0035]
There are various valve structures for the bathtub hot water outflow control valve 16 provided in the fountain pipe 9 and the hot water storage outflow control valve 25 provided in the hot water outflow pipe 24. The flow rate may be adjusted by controlling with a control device using a micro computer according to the temperature. However, as shown in Fig. 3, an orifice flow control valve using a baffle plate or a shape memory alloy is used. This is convenient because the structure is simple and the flow rate can be adjusted relatively accurately according to the hot water temperature.
[0036]
In this orifice flow control valve, the flow rate is adjusted by changing the diameter of the orifice pipe 28 from the one-dot chain line state to the solid line state according to the hot water temperature, for example, depending on the hot water temperature. The flow rate is adjusted by continuously changing the tube diameter by changing the tube diameter, or the flow rate is adjusted by changing the tube diameter as a shape memorized at the temperature set as the shape memory alloy. .
[0037]
When this orifice flow rate control valve is used as the bathtub hot water outflow control valve 16, the opening of the valve is adjusted to 100% when the temperature of the bath water 2 is 40 ° C and 50% when the temperature of the bath water is 30 ° C. is there.
[0038]
Further, when the orifice flow rate control valve is used as the stored hot water outflow control valve 25, the opening degree of the valve is adjusted to 30% when the temperature of the stored hot water 18 is 85 ° C, and to 100% when the temperature of the stored hot water 18 is 50 ° C. It is.
[0039]
Furthermore, the diameters of the fountain pipe 9 and the stored hot water outflow pipe 24 are such that when the opening of the bathtub hot water outflow control valve 16 is 50% and the opening of the stored hot water outflow control valve 25 is 50%, 9 is designed so that the ratio of the amount of the hot water 2 flowing to 9 and the amount of the hot water 18 flowing to the hot water outlet pipe 24 is 2: 1.
[0040]
With such a design, even when the temperature of the bath water 2 is 30 ° C., the bath temperature can be adjusted to 40 ° C. by adjusting the temperature for about 30 minutes, and the bath water 2 and the hot water 18 sprayed into the bath 1 are mixed. The temperature of the hot water can be kept below 46 ° C.
[0041]
Next, a hot water circulation path for cleaning bath water will be described based on the piping diagrams of FIGS. 4 and 5. Here, only the filtration device 5 is shown as the cleaning device, and ozone sterilization and other devices are shown. Is omitted.
[0042]
In FIG. 4, the hot water temperature sensor 15 detects that the temperature of the bathtub hot water 2 circulating through the cleaning pipe 14 is a predetermined bath temperature, and the hot water circulation path when the hot water temperature adjustment is not particularly necessary is indicated by an arrow. It is shown.
[0043]
In this case, based on the detection result of the hot water temperature sensor 15, the control device 27 closes the hot water shutoff valve 26 provided in the hot water storage outflow pipe 24, and the hot water temperature control line 22 includes the bathtub hot water 2 and the hot water storage hot water. 18 will not flow at all.
[0044]
Accordingly, the bathtub water 2 sucked up from the suction pipe 3 by the operation of the circulation pump 6 flows only through the cleaning pipe 14 and is filtered by the filtration device 5 and then through the bathtub hot water outflow regulating valve 16 which is 100% open. Only the circulation which is again ejected from the tube into the bathtub 1 is performed.
[0045]
FIG. 5 shows the hot water circulation path when the hot water temperature sensor 15 detects that the temperature of the bathtub hot water 2 circulating through the cleaning conduit 14 has fallen below the predetermined bathing temperature, and the hot water temperature adjustment is necessary. Shown with an arrow.
[0046]
In this case, based on the detection result of the hot water temperature sensor 15, the control device 27 opens the hot water shutoff valve 26 provided in the hot water hot water outlet pipe 24, and the bathtub hot water outflow control valve 16 provided in the jet water pipe 9. Further, the heat storage hot water outflow control valve 25 has an opening degree according to the temperature of the bathtub hot water 2 and the heat storage hot water 18 based on the valve design as described above, and the hot water flows through the hot water temperature control line 22 to adjust the hot water temperature. It becomes a state to be performed.
[0047]
That is, the bathtub hot water 2 circulating through the cleaning pipe 14 has the opening degree corresponding to the hot water temperature of the bathtub hot water outflow control valve 16 after the filtration in the filtering device 5 is finished. According to the opening degree of the valve 16, it flows separately from the direction of the fountain pipe 9 and the direction of the bathtub hot water outflow pipe 23.
[0048]
Of course, the bath water 2 directed toward the fountain pipe 9 is jetted as it is to the bathtub 1, while the bath water 2 directed toward the tub hot water outlet pipe 23 flows into the heat storage tank 17 from the bath water inlet 20 at the bottom.
[0049]
As a result, the hot water 18 stored in the heat storage tank 17 is pushed by the bath water 2 that has flowed in and flows out from the hot water outlet 21 to the hot water outlet pipe 24, and has an opening corresponding to the temperature of the hot water. It flows into the fountain pipe 9 through the hot water storage flow rate adjusting valve 25 and the open hot water storage shutoff valve 26, enters the bathtub hot water 2, and jets into the bathtub 1.
[0050]
In this way, the temperature of the bath water 2 is adjusted by using the hot water temperature control line 22 in which the temperature of the bath water 2 which has been lowered is replaced with the hot water storage water 18 by an amount proportional to the temperature drop. Is continued until the hot water temperature sensor 15 detects that the bathing temperature has reached a predetermined bathing temperature.
[0051]
In the adjustment of the hot water temperature using the hot water temperature adjusting pipe 22 as described above, when the temperature of the bathtub hot water 2 is greatly reduced, the opening degree of the bathtub hot water outflow control valve 16 is proportional to the temperature. Therefore, a large amount of hot water flows out to the bathtub hot water outflow pipe 23, and accordingly, the hot water 18 in the heat storage tank 17 originally flows out to the hot water storage outflow pipe 24.
[0052]
However, since the hot water storage outflow pipe 24 is provided with a hot water storage outflow amount adjusting valve 25 whose opening degree is adjusted so that the amount of outflow is inversely proportional to the temperature of the hot water storage 18, the heat storage hot water 18 has a high heat storage temperature. The outflow amount of the hot water 18 is limited.
[0053]
As a result, the bath water 2 that has flowed out to the regenerator hot water outflow pipe 24 in a large amount due to the low temperature cannot flow all into the heat accumulator tank 17 when the temperature of the regenerator water 18 is high, and the rest goes to the fountain pipe 9. The bath water 2 is recirculated and the hot water 2 is replaced with a large amount of hot water 18 at a time to prevent a large amount of hot water from being ejected from the fountain pipe 9 to the bathtub 1.
[0054]
【The invention's effect】
The present invention is configured and operated as described above, and provides a bath water cleaning method capable of keeping bath water at an appropriate temperature for 24 hours, and at the same time, a simple bath water cleaning device that realizes this method. To do.
[0055]
As a result, it is possible to enjoy a clean and suitable bath in an economical state at any time for 24 hours.
