Description

【0001】
【発明の属する技術分野】
本発明は、浴槽内の浴槽水を循環して浄化することで、浴槽水の長期使用を可能とする浴槽水循環浄化装置に関するものである。
【0002】
【従来の技術】
近年、家庭用の風呂において24時間の入浴を可能とする浴槽水循環浄化装置が提供されている。この浴槽水循環浄化装置は図9に示すようなもので、浴槽水を循環水路1に循環させる循環ポンプ2と、循環水路1の循環ポンプ2よりも下流側に設けたヒータ3と、循環水路1の循環ポンプ2とヒータ3との間から分岐したバイパス路4と、バイパス路4の途中に設けた塩素発生装置Aと、バイパス路4を流れる浴槽水を塩素発生装置Aよりも下流側において浄化するためのろ過槽5を備え、バイパス路4の下流側端部が循環水路1の浴槽への吐出口7付近の絞り部において連通接続されて循環水路1を流れる浴槽水の水流によりバイパス路4を流れる浴槽水がエゼクター効果で吸引して、ヒータ3で加温された浴槽水とろ過槽5により浄化された浴槽水とを合流して吐出口7からジェット噴射するようになっている。また、殺菌する際には塩素発生装置Aで生成した塩素水をろ過槽5を経て吐出口7から浴槽内に吐出してろ過槽5、配管、浴槽6内の浴槽水を塩素水で殺菌するようになっている。
【0003】
そして、循環水路1の両端部の吸い込み口と吐出口7とは浴槽6内の浴槽水内に浸漬してあるか又は浴槽6の側壁に接続してあり、循環ポンプ2、ヒータ3、塩素発生装置A、ろ過槽5は浄化装置本体B内に内装され、この浄化装置本体Bは浴槽から離れた個所(例えば浴室外)に配設してある。
【0004】
ここで、ろ過槽5内のろ材の交換やろ過槽5の保守、点検、あるいは塩素発生装置Aにおいて発生させる塩素の原料となる食塩の補充をする場合には、浴槽水循環装置の運転スイッチをオフにした状態で行うものである。この時、浄化装置本体Bの外面付近において、図9に示すように循環水路1の循環ポンプ2の上流側に手動で開閉する開閉弁8が設けてあると共にヒータ3の下流側で且つ絞り部よりも上流側に開閉弁9を設けてあり、この手動開閉弁8、9を閉じた状態で、上記ろ過槽5内のろ材の交換やろ過槽5の保守、点検、あるいは塩素発生装置Aにおいて発生させる塩素の原料となる食塩の補充をするものである。
【0005】
ところが、浄化装置本体を浴槽から離れて設置する場合、浄化装置本体Bに内装したろ過槽5や塩素発生装置Aが浴槽の水面よりも下とならないように設置するようになっているのであるが、施工現場においては浄化装置本体Bに内装したろ過槽5や塩素発生装置Aが浴槽の水面よりも下に配置されることがあり、このような場合、上記ろ過槽5内のろ材5aの交換やろ過槽5の保守、点検、あるいは塩素発生装置Aにおいて発生させる塩素の原料となる食塩の補充を行う際に、浴槽水が図9の矢印のようにバイパス路4を介してろ過槽5や塩素発生装置A側に流れてろ過槽5や塩素発生装置Aの保守、点検、補充等のために開口した部分から溢れ出るという問題がある。
【0006】
【発明が解決しようとする課題】
本発明は上記の従来例の問題点に鑑みて発明したものであって、その目的とするところは、浄化装置本体に内装したろ過槽や塩素発生装置が浴槽の水面よりも下に配置された場合であっても、上記ろ過槽内のろ材の交換やろ過槽の保守、点検、あるいは塩素発生装置において発生させる塩素の原料となる食塩の補充を行う際に、浴槽水がバイパス路を介してろ過槽や塩素発生装置から溢れ出るのを防止することができる浴槽水循環浄化装置を提供するにある。
【0007】
【課題を解決するための手段】
上記課題を解決するために本発明に係る浴槽水循環浄化装置は、浴槽水を循環水路1に循環させる循環ポンプ2と、循環水路1の循環ポンプ2よりも下流側に設けたヒータ3と、循環水路1の循環ポンプ2とヒータ3との間から分岐したバイパス路4と、バイパス路4の途中に設けた塩素発生装置Aと、バイパス路4を流れる浴槽水を塩素発生装置Aよりも下流側において浄化するためのろ過槽5を備えた浴槽水循環浄化装置において、バイパス路4の下流側端部が循環水路1の浴槽6への吐出口7付近の絞り部7aにおいて連通接続されて循環水路1を流れる浴槽水の水流によりバイパス路4を流れる浴槽水がエゼクター効果で吸引されるように構成し、循環水路1の循環ポンプ2の上流側に手動開閉弁8を設けると共にヒータ3の下流側で且つ絞り部7aよりも上流側に手動開閉弁9を設け、バイパス路4のろ過槽5よりも下流側にろ過槽5側から下流側にのみ浴槽水を流し且つ下流側からろ過槽5側に浴槽水が逆流するのを阻止する逆止弁10を設けて成ることを特徴とするものである。このような構成とすることで、ろ過槽5内のろ材の交換やろ過槽の保守、点検、あるいは塩素発生装置Aにおいて発生させる塩素の原料となる食塩の補充を行うに当たっては、運転スイッチ11をオフにすると共に、循環水路1の循環ポンプ2の上流側に設けた手動開閉弁8と、ヒータ3の下流側で且つ絞り部7aよりも上流側に設けた手動開閉弁9を手動で閉じ、循環水路1から浴槽内の湯水がろ過槽5や塩素発生装置A側に流入しないようにした状態で行うものであり、この場合、バイパス路4のろ過槽5よりも下流側にろ過槽5側から下流側にのみ浴槽水を流し且つ下流側からろ過槽5側に浴槽水が逆流するのを阻止する逆止弁10を設けてあることで、ろ過槽5や塩素発生装置Aが浴槽の水面よりも下に配置された場合であっても、逆止弁10により浴槽内の湯水がバイパス路4からろ過槽5や塩素発生装置Aに逆流して、ろ過槽5や塩素発生装置Aから溢れ出ることがないようになっている。
【0008】
また、浴槽水を循環水路1に循環させる循環ポンプ2と、循環水路1の循環ポンプ2よりも下流側に設けたヒータ3と、循環水路1の循環ポンプ2とヒータ3との間から分岐したバイパス路4と、バイパス路4の途中に設けた塩素発生装置Aと、バイパス路4を流れる浴槽水を塩素発生装置Aよりも下流側において浄化するためのろ過槽5を備えた浴槽水循環浄化装置において、バイパス路4の下流側端部が循環水路1の浴槽への吐出口7付近の絞り部7aにおいて連通接続されて循環水路1を流れる浴槽水の水流によりバイパス路4を流れる浴槽水がエゼクター効果で吸引されるように構成し、循環水路1の循環ポンプ2の上流側に手動開閉弁8を設けると共にヒータ3の下流側で且つ絞り部7aよりも上流側に手動開閉弁9を設け、バイパス路4のろ過槽5よりも下流側に弁12を設け、浴槽水循環浄化装置の運転スイッチ11をオフにした際に、弁12を閉じるように制御する制御部13を設けて成ることを特徴とするものであってもよい。このような構成とすることで、ろ過槽5内のろ材の交換やろ過槽5の保守、点検、あるいは塩素発生装置Aにおいて発生させる塩素の原料となる食塩の補充を行うに当たっては、運転スイッチ11をオフにすると共に、循環水路1の循環ポンプ2の上流側に設けた手動開閉弁8と、ヒータ3の下流側で且つ絞り部7aよりも上流側に設けた手動開閉弁9を手動で閉じ、循環水路1から浴槽内の湯水がろ過槽5や塩素発生装置A側に流入しないようにした状態で行うものであるが、この場合、バイパス路4のろ過槽5よりも下流側に弁12を設け、浴槽水循環浄化装置の運転スイッチ11をオフにした際に、弁12を閉じるように制御する制御部13を設けてあるので、ろ過槽5や塩素発生装置Aが浴槽6の水面よりも下に配置された場合であっても、浴槽6内の湯水がバイパス路4からろ過槽5や塩素発生装置Aに逆流して、ろ過槽5や塩素発生装置Aから溢れ出ることがないようになっている。
【0009】
【発明の実施の形態】
以下、本発明を添付図面に示す実施形態に基づいて説明する。
【0010】
図1には本発明の装置の配管構成図の一実施形態が示してある。循環水路1は一端に吸い込み口14を設けると共に他端に吐出口7を設けてあり、上記吸い込み口14と吐出口7とは浴槽6内の浴槽水中に浸漬させてあるか又は浴槽6の側壁に接続してある。
【0011】
循環水路1には上流側から下流側にかけて順に循環ポンプ2、弁15、ヒータ3が設けてあり、また、循環水路1の循環ポンプ2よりも下流側で且つ弁15よりも上流側からバイパス路4が分岐してあり、このバイパス路4には上流側から下流側にかけて順に弁16、ろ過槽5、弁12が設けてあり、バイパス路4の下流側端部は循環水路1の浴槽6への吐出口7付近に設けた絞り部7aにおいて循環水路1に連通接続されており、循環水路1を流れる浴槽水の水流によりバイパス路4を流れる浴槽水がエゼクター効果で吸引されるように構成してある。そして、バイパス路4の下流側端部の絞り部7aとの連通接続部分と弁12との間に逆止弁10が設けてある。この逆止弁10はバイパス路4のろ過槽5よりも下流側にろ過槽5側から下流側にのみ浴槽水を流し且つ下流側からろ過槽5側に浴槽水が逆流するのを阻止するようになっている。
【0012】
図4には逆止弁10の一実施形態が示してある。図4に示すものはバイパス路4の一部を逆止弁付きジョイント部材32で構成した例である。第1ジョイント部材33の端部の嵌め込み筒部34を第2ジョイント部材50の嵌め込み凹部35にパッキン36を介して水密的に嵌め込んで接続し、嵌め込み筒部34の端部の大径孔部34a内と嵌め込み凹部35の底部空所35aとで構成される空所37内に空所37の径よりも径が小さいボール弁38を移動自在に納装し、大径孔部34aの底部からボール支持突部34bを突設し、底部空所35aの底部に弁孔35bを形成することで逆止弁付きジョイント部材32を構成してある。上記、逆止弁付きジョイント部材32は嵌め込み筒部34の後端段部34dを後述する洗浄装置本体Bの外郭を構成するケーシング51に当てると共に第2ジョイント部材50をねじ具39によりケーシング51に固着することで洗浄装置本体Bに取付けてある。
【0013】
しかして、図4の矢印方向、つまり、バイパス路4の上流側から下流側に浴槽水が流れる場合には、ボール弁38がボール支持突起34bに当たり、浴槽水は空所37内においてボール弁38の周囲を流れてボール支持突起34b間の隙間34cから下流側に流れるものである。一方、バイパス路4の下流側から上流側に浴槽水が流れる場合にはボール弁38が弁孔35bに嵌まり込んで弁孔35bを閉じ弁孔35bより下流側に浴槽水が流れないようになっている。
【0014】
バイパス路4には塩素発生装置Aが設けられるが、本実施形態においてはバイパス路4に直接塩素発生装置Aを設けるのではなく、バイパス路4の弁16の上流側から分岐水路17を分岐し、この分岐水路17に塩素発生装置Aが設けてあり、分岐水路17の下流側端部がバイパス路4の弁16の下流側に連通接続してある。分岐水路17は途中で三方弁20を介して第1分岐水路18と第2分岐水路19とに更に分岐し、第1分岐水路18の下流側端部には電解槽21が設けられ、電解槽21から分岐水路17の下流側を構成する水路が導出されて該水路の下流側端部(つまり分岐水路17の下流側端部)がバイパス路4の弁16とろ過槽5との間に連通接続してある。第2分岐水路19の途中に塩溶解槽22が設けてあり、第2分岐水路19の下流側端部が電解槽21に連通接続してある。そして、上記三方弁20、電解槽21、塩溶解槽22により塩素発生装置Aが構成してある。
【0015】
ここで、塩溶解槽22には食塩が収納される。また、電解槽21は一対の不溶性電極板よりなる電極26を隔膜を介することなく対向配置した無隔膜タイプのものとして形成してある。ここで、電極26を構成する電極板の形状は電解槽21の下方まで達する長方形である。電極26には直流電圧が印加されるようになっており、電極26への電圧の印加は制御部13の制御により行われる。塩溶液には塩素イオン(Cl)が含まれているが、電解槽21で電極26に直流電圧を印加して塩素イオン(Cl)の一部を電気分解すると、塩素イオン(Cl)は塩素(Cl)や次亜塩素酸イオン(ClO)に交換され、浴槽水に殺菌力を持たせることができるようになっている。
【0016】
ろ過槽5内には中空糸膜のような精密ろ過材よりなるろ材5aが設けてある。ろ過槽5のろ材5aの上流側に排出管30の一端部が接続してあり、この排出管30の他端部と排水管24の一端部と洗浄循環用管25の一端部とが三方弁23を介して接続してあり、洗浄循環用管25の他端部は循環水路1の循環ポンプ2よりも上流側に連通接続してある。
【0017】
上記のような浴槽水循環浄化装置において、循環ポンプ2ヒータ3、塩素発生装置A、ろ過槽5、弁12、15、16、三方弁20、23、制御部13等は浄化装置本体B内に内装してある。浄化装置本体Bの外面側には運転スイッチ11が設けてある。また、図1に示すように、循環水路1の循環ポンプ2の上流側に手動開閉弁8を設けると共にヒータ3の下流側で且つ絞り部7aよりも上流側に手動開閉弁9を設けてある。そして、循環水路1の吸い込み口14と吐出口7とは前述のように浴槽6内の浴槽水内に浸漬してあるか又は浴槽6の側壁に接続してあるが、浄化装置本体Bは浴槽6から離れた個所(例えば浴室外)に配設してある。
【0018】
浴槽水循環浄化装置の運転に当たっては、手動開閉弁8、9は開状態にし、運転スイッチ11をオンにして運転を行うものである。
【0019】
浴槽水循環浄化装置の運転モードとしては、「通常循環」モード、「食塩水供給」モード、「電解」モード、「塩素水供給」モード等の諸モードがあり、運転スイッチ11をオンにすることで制御部13により上記諸モードを自動的に切り替えて運転が行われるようになっている。すなわち、上記モード切り換えによる各弁の切り換え、循環ポンプ2の運転、電極26への電圧の印加等の制御が制御部13からの信号により行われるものである。
【0020】
ここで、本発明の浴槽水循環浄化装置は通常循環運転時には、弁12、弁15、弁16をいずれも開、三方弁20、23をいずれも閉にして循環ポンプ2を運転するように制御されるものであり、この場合、循環ポンプ2の運転により吸い込み口14から循環水路1に吸い込まれた浴槽水の一部がヒータ3で加温されて吐出口7側に送られ、また、浴槽水の他の一部がバイパス路4に流れ、ろ過槽5を通過する際にろ材5aによりろ過されることで浄化されて吐出口7側に送られる。そして、循環水路1を流れる加熱された浴槽水が吐出内7付近に設けた絞り部7aを通過する際に、バイパス路4を流れる浄化された浴槽水がエゼクター効果により循環水路1を流れる加温された浴槽水側に吸い込まれて合流し、合流した浴槽水が吐出口7から浴槽6内の浴槽水中にジェット水となって噴射されるものである。これが「通常循環モード」である。ここで、バイパス路4の下流側端部は循環水路1の浴槽6への吐出口7付近に設けた絞り部7aにおいて循環水路1に連通接続され、循環水路1を流れる浴槽水の水流によりバイパス路4を流れる浴槽水がエゼクター効果で吸引されるようになっているので、ろ過槽5を通過して流れる浴槽水がスムーズに流れて循環流路1を流れる加温された浴槽水と合流することができて、浴槽水がろ過槽5のろ材5aをスムーズに通過して効果的に浄化できるようになっている。そして、吐出部7から浴槽水をジェット噴射するために吐出部7の近くに設けた絞り部7aにバイパス路4の下流側端部を連通接続することで、上記のように、ろ材5aをスムーズに通過できるようにするに当たって別途特別な装置を必要としないものである。
【0021】
殺菌(または制菌)運転に当っては、「食塩水供給」モード→「電解」モード→「塩素水供給」モードの順で運転するものである。すなわち、弁12、弁15、弁16をいずれも開とし、三方弁20を第2分岐路19側のみが開となって第2分岐路19側に浴槽水が流れるようにし、また、三方弁23を閉にした状態で循環ポンプ2を運転することで、塩溶解槽22から食塩水が電解槽21に供給される(これが「食塩水供給」モードである)。このようにして電解槽21に食塩水を供給した後、弁12、弁15、弁16をいずれも開とし、三方弁20、23をいずれも閉とした状態で電極26に電圧を印加して電気分解することで、塩素を発生させる(これが「電解」モードである)。この場合循環ポンプ2は運転しておく。次に、弁12、弁15、弁16をいずれも開とし、三方弁20を第1分岐路18側のみが開となって第1分岐路18側に浴槽水が流れるようにし、また、三方弁23を閉にし、この状態で循環ポンプ2を運転すると電解槽21内の塩素水がろ過槽5に供給され、ろ材5aを通過して浴槽水と一緒に浴槽6に流れ込む(これが「塩素水供給」モードである)。このように塩素水を循環水路1に流すことで、浴槽水や装置内の病原性細菌を抑制し、不快感を与えるヌメリを取り除くものである。
【0022】
ろ過槽5内のろ材5aを洗浄するに当たっては、弁12、弁15、三方弁20をそれぞれ閉とし、三方弁23を排出管30と洗浄循環用管25とが連通するように開とし(この場合排水管24側は閉である)、この状態で循環ポンプ2を運転することで浴槽水が循環ポンプ2→ろ過槽5のろ材5aの上流側→排出管30→洗浄循環用管25→循環ポンプ2というように流れ、上記流れで循環することでろ過槽5内のろ材5aを洗浄するものである。次に、弁12、弁15、三方弁20をそれぞれ閉とし、三方弁23を排出管30と排水管24とが連通するように切り換え(この場合、洗浄循環用管25側は閉である)、この状態で循環ポンプ2を運転することで上記ろ材5aを洗浄して汚れた洗浄水が排水管24から外部に排水されるものである。
【0023】
ところで、ろ過槽5内のろ材5aの交換やろ過槽5の保守、点検、あるいは塩素発生装置Aに設けた塩溶解槽22内への食塩の補充を行う場合には、浴槽水循環装置の運転スイッチ11をオフにすると共に洗浄装置本体Bの外面側に位置させた手動開閉弁8、9を手動で閉じた後、ろ過槽5内のろ材5aの交換やろ過槽5の保守、点検、あるいは塩素発生装置Aにおいて発生させる塩素の原料となる食塩の補充をするものである。
【0024】
この場合、洗浄装置本体Bが浴槽6から離れた個所に設置してあっても、吸い込み口14と吐出口7とを両端部に有する循環水路1は洗浄装置本体Bの外面に設けた手動開閉弁8、9を手で閉じることで、循環水路1を通して浴槽6内の浴槽水が交換や保守、点検、あるいは補充のために蓋を開けたろ過槽5の上開口や、塩溶解槽22の上開口から溢れ出ることはない。
【0025】
しかしながら、浴槽6から離れた個所に浄化装置本体Bを設置した場合、浄化装置本体Bに内装したろ過槽5や塩素発生装置Aが浴槽6の水面よりも下位置となるように設置してしまう場合があり、この場合には水頭圧により浴槽水がバイパス路4の上流側からろ過槽5や塩溶解槽22側に逆流することになる。しかしながら本実施形態においては、バイパス路4のろ過槽5よりも下流側にろ過槽5側から下流側にのみ浴槽水を流し且つ下流側からろ過槽5側に浴槽水が逆流するのを阻止する逆止弁10を設けてあるので、ろ過槽5や塩素発生装置Aが浴槽の水面よりも下に配置された場合であっても、逆止弁10により浴槽6内の湯水がバイパス路4からろ過槽5や塩溶解槽22に逆流して、ろ過槽5や塩溶解槽22から溢れ出るのを防止できるのである。
【0026】
本実施形態によれば、新設の浴槽水循環浄化装置に逆止弁10を設けるだけでなく、すでに設置済みの既設の浴槽水循環浄化装置であっても、バイパス路4に逆止弁10を取付けるだけで、ろ過槽5内のろ材5aの交換やろ過槽5の保守、点検、あるいは塩素発生装置Aにおいて発生させる塩素の原料となる食塩を補充する際に浴槽6内の浴槽水が逆流して溢れるのを防止できるものである。
【0027】
ところで、ろ過槽5を浄化装置本体Bに取付けたり、外したりするに当たっては例えば、次のようにして行う。すなわち、図5、図6、図7に示すように、ろ過槽5の底面部からOリング41を設けた接続筒部42を垂設し、更にろ過槽5の底面部に弾性を有する固定金具43の上端部を取付けて、固定金具43を接続筒部42の外側に位置させ、接続筒部42を浄化装置本体Bに設けたバイパス路4の一部を構成するろ過槽継手40に水密的に嵌め込み、固定金具43に設けた係止孔44をろ過槽継手40の上端部のフランジ部45に弾性的に係止することで取付けるものであり、取り外す場合には固定金具43の下部を外側にずらして広げることで係止を解除して外すことができる。ここで、固定金具43の下端部を下方程外側に位置するように傾斜したガイド片43aを設けておくと、取付けの際に上方から挿入するときガイド片43aがガイドとなってフランジ部45に当たりながらガイドしてスムーズに係止でき、また、取り外す際には傾斜したガイド片43aを指で摘んで外側にずらして広げることができるものである。
【0028】
次に、図8に基づいて本発明の他の実施形態につき説明する。
【0029】
図8に示す本実施形態の浴槽水循環浄化装置は図1に示す浴槽水循環浄化装置における配管構造、運転モード、その制御と同じであるので、重複する説明は省略し、異なる点のみ説明する。すなわち、図1に示す実施形態においては、循環水路1を通して浴槽6内の浴槽水が交換や保守、点検、あるいは補充の際に、ろ過槽5の上開口や、塩溶解槽22の上開口から溢れ出ないようにするに当たって、バイパス路4のろ過槽5よりも下流側に逆止弁10を設けた例につき説明したが、本実施形態においては、図1のように逆止弁10を設けることなく、バイパス路4のろ過槽5よりも下流側に本来的に備わっている弁12を浴槽水循環浄化装置の運転スイッチ11をオフにした際に自動的に閉じるように制御部13により制御するように構成した点に特徴がある。
【0030】
しかして、本実施形態においては、ろ過槽5内のろ材の交換やろ過槽の保守、点検、あるいは塩素発生装置Aにおいて発生させる塩素の原料となる食塩の補充を行うに当たっては、運転スイッチ11をオフにすると共に、更に、循環水路1の循環ポンプ2の上流側とヒータ3の下流側とにそれぞれ設けた手動開閉弁8、9を手動で閉じ、循環水路1から浴槽内の湯水がろ過槽5や塩素発生装置A側に流入しないようにした状態で行うものであるが、この場合、運転スイッチ11をオフにすると弁12が自動的に閉じるので、ろ過槽5や塩素発生装置Aが浴槽の水面よりも下に配置された場合であっても、浴槽内の湯水がバイパス路4からろ過槽5や塩溶解槽22側に逆流して、ろ過槽5や塩溶解槽22から溢れ出ることがないのである。
【0031】
この実施形態においては図1の実施形態のように別途逆止弁を設ける必要がないものである。
【0032】
【発明の効果】
上記の請求項1記載の本発明にあっては、バイパス路の下流側端部が循環水路の浴槽への吐出口付近の絞り部において連通接続されて循環水路を流れる浴槽水の水流によりバイパス路を流れる浴槽水がエゼクター効果で吸引されるように構成し、循環水路の循環ポンプの上流側に手動開閉弁を設けると共にヒータの下流側で且つ絞り部よりも上流側に手動開閉弁を設け、バイパス路のろ過槽よりも下流側にろ過槽側から下流側にのみ浴槽水を流し且つ下流側からろ過槽側に浴槽水が逆流するのを阻止する逆止弁を設けてあるので、ろ過槽内のろ材の交換やろ過槽の保守、点検、あるいは塩素発生装置において発生させる塩素の原料となる食塩の補充を行うに当たって、ろ過槽や塩素発生装置が浴槽の水面よりも下に配置された場合であっても、逆止弁により浴槽内の湯水がバイパス路からろ過槽や塩素発生装置に逆流して、ろ過槽や塩素発生装置から溢れ出ることがなく、交換、保守、点検、補充等の作業が簡単にでき、また、周囲を溢れ出る浴槽水で濡らすことがないものであり、また、逆止弁を設けるのみでよいので、既設の浴槽水循環浄化装置であっても、バイパス路に逆止弁を取付けるのみで上記のような水漏れ防止効果を簡単に発揮できるのである。
【0033】
また、請求項2記載の発明にあっては、バイパス路の下流側端部が循環水路の浴槽への吐出口付近の絞り部において連通接続されて循環水路を流れる浴槽水の水流によりバイパス路を流れる浴槽水がエゼクター効果で吸引されるように構成し、循環水路の循環ポンプの上流側に手動開閉弁を設けると共にヒータの下流側で且つ絞り部よりも上流側に手動開閉弁を設け、バイパス路のろ過槽よりも下流側に弁を設け、浴槽水循環浄化装置の運転スイッチをオフにした際に、弁を閉じるように制御する制御部を設けてあるので、ろ過槽内のろ材の交換やろ過槽の保守、点検、あるいは塩素発生装置において発生させる塩素の原料となる食塩の補充を行うに当たっては、運転スイッチをオフにすると共に、循環水路の循環ポンプの上流側に設けた手動開閉弁と、ヒータの下流側で且つ絞り部よりも上流側に設けた手動開閉弁を手動で閉じて作業を行うことができる。この場合、運転スイッチをオフにすると、バイパス路の浄化槽の下流の弁が自動的に閉じるように制御され、ろ過槽や塩素発生装置が浴槽の水面よりも下に配置された場合であっても、浴槽内の湯水がバイパス路からろ過槽や塩素発生装置に逆流して、ろ過槽や塩素発生装置から溢れ出ることがないものであり、また、バイパス路の浄化槽の下流側に本来備わっている弁を利用して簡単な構成で上記浴槽水の逆流防止が図れるものである。

In the filtration tank 5, a filter medium 5a made of a precision filtration medium such as a hollow fiber membrane is provided. One end of a discharge pipe 30 is connected to the upstream side of the filter medium 5 a of the filtration tank 5, and the other end of the discharge pipe 30, one end of the drain pipe 24, and one end of the washing circulation pipe 25 are connected to each other by a three-way valve. The other end of the washing circulation pipe 25 is connected to the circulation water passage 1 upstream of the circulation pump 2.
[0017]
In the bathtub water circulation purifier as described above, the circulation pump 2 heater 3, the chlorine generator A, the filtration tank 5, the valves 12, 15, 16, the three-way valves 20, 23, the control unit 13 and the like are provided inside the purifier main body B. I have. An operation switch 11 is provided on the outer surface side of the purification device main body B. Also, As shown in FIG. The upstream side of the circulation pump 2 in the circulation channel 1 A manual on-off valve 8 and Downstream side of heater 3 And a manual on-off valve 9 upstream of the throttle portion 7a. Is provided. The suction port 14 and the discharge port 7 of the circulation channel 1 are immersed in the bathtub water in the bathtub 6 or connected to the side wall of the bathtub 6 as described above. It is located at a location away from 6 (for example, outside the bathroom).
[0018]
In operation of the bathtub water circulation purification device, the manual on-off valves 8 and 9 are opened and the operation switch 11 is turned on to perform operation.
[0019]
The operation mode of the bathtub water circulation purification device includes various modes such as a “normal circulation” mode, a “salt water supply” mode, an “electrolysis” mode, and a “chlorine water supply” mode. The control unit 13 automatically switches the various modes to perform the operation. That is, control of switching of each valve by the mode switching, operation of the circulation pump 2, application of voltage to the electrode 26, and the like are performed by a signal from the control unit 13.
[0020]
Here, the bath water circulation purifying apparatus of the present invention is controlled such that the valve 12, the valve 15, and the valve 16 are all opened and the three-way valves 20, 23 are closed to operate the circulation pump 2 during the normal circulation operation. In this case, a part of the bathtub water sucked into the circulation channel 1 from the suction port 14 by the operation of the circulation pump 2 is heated by the heater 3 and sent to the discharge port 7 side. The other part flows into the bypass passage 4 and is filtered by the filter medium 5 a when passing through the filtration tank 5 to be purified and sent to the discharge port 7 side. Then, when the heated bathtub water flowing through the circulation channel 1 passes through the throttle portion 7a provided near the inside of the discharge 7, the purified bathtub water flowing through the bypass channel 4 flows through the circulation channel 1 by the ejector effect. The combined bathtub water is sucked into the combined bathtub water side, and the combined bathtub water is jetted from the discharge port 7 into the bathtub water in the bathtub 6 as jet water. This is the “normal circulation mode”. Here, the downstream end of the bypass passage 4 is connected to the circulation passage 1 at a throttle portion 7 a provided near the discharge port 7 to the bath 6 of the circulation passage 1, and is bypassed by the bathtub water flowing through the circulation passage 1. Since the bathtub water flowing through the path 4 is sucked by the ejector effect, the bathtub water flowing through the filtration tank 5 flows smoothly and merges with the heated bathtub water flowing through the circulation flow path 1. As a result, the bathtub water can smoothly pass through the filter medium 5a of the filter tank 5 and be effectively purified. Then, by connecting the downstream end of the bypass passage 4 to the throttle part 7a provided near the discharge part 7 for jetting bathtub water from the discharge part 7, the filter medium 5a is smoothly connected as described above. No special device is required to allow the air to pass through.
[0021]
In the sterilization (or bacteriostatic) operation, the operation is performed in the order of “salt water supply” mode → “electrolysis” mode → “chlorine water supply” mode. That is, the valve 12, the valve 15, and the valve 16 are all opened, and the three-way valve 20 is opened only on the side of the second branch 19 so that bathtub water flows to the side of the second branch 19. By operating the circulation pump 2 in a state where 23 is closed, the saline solution is supplied from the salt dissolving tank 22 to the electrolytic tank 21 (this is a “salt water supply” mode). After supplying the saline solution to the electrolytic cell 21 in this manner, a voltage is applied to the electrode 26 with all of the valves 12, 15, and 16 opened and the three-way valves 20, 23 closed. Electrolysis produces chlorine (this is the "electrolysis" mode). In this case, the circulation pump 2 is operated. Next, the valve 12, the valve 15, and the valve 16 are all opened, and the three-way valve 20 is opened only on the first branch passage 18 side so that bathtub water flows to the first branch passage 18 side. When the valve 23 is closed and the circulation pump 2 is operated in this state, the chlorine water in the electrolytic cell 21 is supplied to the filtration tank 5, passes through the filter medium 5a, and flows into the bath 6 together with the bath water (this is referred to as "chlorine water"). Supply mode). By flowing chlorine water in the circulation channel 1 in this manner, bath water and pathogenic bacteria in the apparatus are suppressed, and slime that gives discomfort is removed.
[0022]
In cleaning the filter medium 5a in the filtration tank 5, the valve 12, the valve 15, and the three-way valve 20 are closed, respectively, and the three-way valve 23 is opened so that the discharge pipe 30 and the cleaning circulation pipe 25 communicate with each other. In this case, the drain pump 24 is closed), and by operating the circulation pump 2 in this state, the bathtub water is circulated by the circulation pump 2 → the upstream side of the filter medium 5a of the filtration tank 5 → the discharge pipe 30 → the washing circulation pipe 25 → circulation. It flows like the pump 2 and circulates in the above flow to wash the filter medium 5a in the filter tank 5. Next, the valve 12, the valve 15, and the three-way valve 20 are each closed, and the three-way valve 23 is switched so that the discharge pipe 30 and the drain pipe 24 communicate with each other (in this case, the cleaning circulation pipe 25 side is closed). By operating the circulating pump 2 in this state, the filter medium 5a is washed and dirty washing water is drained to the outside from the drain pipe 24.
[0023]
By the way, when replacing the filter medium 5a in the filter tank 5, maintenance and inspection of the filter tank 5, or replenishing the salt into the salt dissolving tank 22 provided in the chlorine generator A, the operation switch of the bathtub water circulation device is used. After turning off 11 and manually closing the manual on-off valves 8 and 9 located on the outer surface side of the cleaning device main body B, the filter medium 5a in the filtration tank 5 is exchanged, and the maintenance and inspection of the filtration tank 5, or chlorine is removed. It replenishes the salt used as the raw material of chlorine generated in the generator A.
[0024]
In this case, even if the cleaning device main body B is installed at a location away from the bathtub 6, the circulating water channel 1 having the suction port 14 and the discharge port 7 at both ends is manually opened and closed provided on the outer surface of the cleaning device main body B. By closing the valves 8 and 9 by hand, the bathtub water in the bathtub 6 passes through the circulating water channel 1 so that the bathtub water in the bathtub 6 can be replaced, maintained, inspected, or refilled. It does not overflow from the upper opening.
[0025]
However, when the purifying apparatus main body B is installed at a location away from the bathtub 6, the filter tank 5 and the chlorine generator A provided inside the purifying apparatus main body B are installed so as to be located below the water surface of the bathtub 6. In this case, the bath head water flows backward from the upstream side of the bypass 4 to the filtration tank 5 and the salt dissolving tank 22 due to the head pressure. However, in the present embodiment, bathtub water flows only from the filtration tank 5 side to the downstream side of the bypass passage 4 downstream of the filtration tank 5 and prevents the bathtub water from flowing back from the downstream side to the filtration tank 5 side. Since the check valve 10 is provided, even when the filtration tank 5 and the chlorine generator A are disposed below the water surface of the bathtub, the check valve 10 allows the hot water in the bathtub 6 to flow from the bypass passage 4. It is possible to prevent the water from flowing back to the filtration tank 5 or the salt dissolution tank 22 and overflowing from the filtration tank 5 or the salt dissolution tank 22.
[0026]
According to the present embodiment, not only the check valve 10 is provided in the newly installed bathtub water circulation purification device, but also the existing bathtub water circulation purification device that has already been installed is simply provided with the check valve 10 in the bypass passage 4. When the filter medium 5a in the filter tank 5 is replaced, the filter tank 5 is maintained and inspected, or when the salt as a raw material of chlorine generated in the chlorine generator A is replenished, the bathtub water in the bathtub 6 flows backward and overflows. Can be prevented.
[0027]
By the way, when the filter tank 5 is attached to or detached from the purification device main body B, for example, it is performed as follows. That is, as shown in FIGS. 5, 6, and 7, a connecting cylinder portion 42 provided with an O-ring 41 is vertically suspended from the bottom portion of the filtration tank 5, and further, a fixing bracket having elasticity on the bottom portion of the filtration tank 5. Attach the upper end of 43, fix the fitting 43 outside the connecting cylinder 42, and connect the connecting cylinder 42 to the filtration tank joint 40 which constitutes a part of the bypass passage 4 provided in the purification device main body B in a watertight manner. The fixing hole 43 provided in the fixing bracket 43 is attached to the flange 45 at the upper end of the filtration tank joint 40 by elastically locking the fixing hole 43. The lock can be released and removed by sliding it out. Here, if a guide piece 43a is provided so that the lower end portion of the fixing bracket 43 is located on the outer side toward the lower side, the guide piece 43a serves as a guide and contacts the flange portion 45 when inserted from above at the time of mounting. The guide can be smoothly locked while being guided, and when detached, the inclined guide piece 43a can be picked up by a finger and shifted outward to spread.
[0028]
Next, another embodiment of the present invention will be described with reference to FIG.
[0029]
The bathtub water circulation / purification device of the present embodiment shown in FIG. 8 has the same piping structure, operation mode, and control as the bathtub water circulation / purification device shown in FIG. 1, and therefore, duplicate description will be omitted, and only different points will be described. That is, in the embodiment shown in FIG. 1, when the bathtub water in the bathtub 6 is replaced, maintained, inspected, or replenished through the circulating water channel 1, the bathtub water from the upper opening of the filtration tank 5 or the upper opening of the salt dissolving tank 22. In order to prevent overflow, the example in which the check valve 10 is provided downstream of the filtration tank 5 in the bypass 4 has been described. In the present embodiment, however, the check valve 10 is provided as shown in FIG. The control unit 13 controls the valve 12 inherently provided downstream of the filtration tank 5 of the bypass passage 4 to be automatically closed when the operation switch 11 of the bathtub water circulation purification device is turned off. There is a feature in that it is configured as described above.
[0030]
Thus, in the present embodiment, the operation switch 11 is used to replace the filter medium in the filtration tank 5, maintain and check the filtration tank, or replenish the salt used as the raw material of chlorine generated in the chlorine generator A. In addition to turning off the water, the manual on-off valves 8 and 9 provided respectively on the upstream side of the circulation pump 2 and the downstream side of the heater 3 of the circulation channel 1 are manually closed. In this case, when the operation switch 11 is turned off, the valve 12 is automatically closed, so that the filtration tank 5 and the chlorine generator A are connected to the bathtub. Even if the water is placed below the water surface, the hot water in the bathtub flows backward from the bypass 4 to the filtration tank 5 or the salt dissolution tank 22 and overflows from the filtration tank 5 or the salt dissolution tank 22. There is no.
[0031]
In this embodiment, it is not necessary to separately provide a check valve unlike the embodiment of FIG.
[0032]

Further, in the invention according to claim 2, the downstream end of the bypass passage is connected in communication with a narrow portion near the discharge port to the bathtub of the circulating water passage, and the bypass passage is formed by the flow of bathtub water flowing through the circulating water passage. The flowing bathtub water is configured to be sucked by the ejector effect, and the upstream side of the circulation pump in the circulation channel With a manual on-off valve Downstream of heater And upstream of the throttle A manual opening / closing valve is provided, a valve is provided downstream of the filtration tank in the bypass passage, and a control unit that controls the valve to close when the operation switch of the bathtub water circulation purification device is turned off is provided. When replacing the filter media in the tank, performing maintenance and inspection of the filter tank, or replenishing the salt that is the source of chlorine generated in the chlorine generator, turn off the operation switch and set the upstream side of the circulation pump in the circulation channel. A manual on-off valve provided in the Downstream of heater Manual on-off valve installed upstream of the throttle Can be closed manually to perform the work. In this case, when the operation switch is turned off, the valve downstream of the septic tank in the bypass path is controlled so as to be automatically closed, and even when the filtration tank or the chlorine generator is disposed below the water surface of the bathtub. The hot water in the bathtub does not flow backward from the bypass to the filter tank or chlorine generator, and does not overflow from the filter tank or chlorine generator, and is inherently provided downstream of the septic tank in the bypass path. The backflow of the bathtub water can be prevented with a simple configuration using a valve.
