Description

【０００１】
【発明の属する技術分野】
本発明は、台所または厨房、洗面所あるいは風呂場等で用いられ、使用時に吐出する水および／または湯を浄化する能力を具備した浄水機能付きシャワーヘッドに関する。
【０００２】
【従来の技術】
従来、洗面所あるいは風呂場等で用いられる洗面装置やシャワー装置等に取り付けられ、水および／または湯の水質浄化能力を具備したシャワーヘッドには、例えば登録実用新案公報第 3007614号記載の塩素除去シャワーヘッドがあった。
この塩素除去シャワーヘッドでは、本体内に水質を浄化するための水質浄化用カートリッジと、シャワー吐出する湯水を浄化水または原水に切り換えるための流路切換弁とが収容されている。
【０００３】
〔問題点〕
このような従来の塩素除去シャワーヘッドにおいては、シャワーヘッドの本体内に収容される流路切換弁が、水質浄化用カートリッジが収容された位置の上流側に配置されているため、水質浄化用カートリッジが把持部に収容されているものでは、流路切換弁の収容容積が小さくなり、流路切換弁を収容部に合わせて小さく形成しなければならず、その形状、構造等も制約され、しかも製造が難しくなる、また、水質浄化用カートリッジが頭部に収容されているものでは、胴部に比較して頭部が重くなり、シャワーヘッドの重量バランスが悪くなって、扱いにくいものとなるという問題点があった。
【０００４】
【発明が解決しようとする課題】
本発明は、従来の技術における前記問題点を解消するためのものであり、この解決のため具体的に設定した課題は、切換弁の形状、構造および収容容積等の制約を大幅に緩めるとともに取扱上も重量バランスの良い形状および構造にすることができる浄水機能付きシャワーヘッドを提供することにある。
【０００９】
【課題を解決するための手段】
前記課題を達成するため具体的に構成した本発明における請求項１に係る浄水機能付きシャワーヘッドは、直接手で持つことができる大きさに形成し、他部品との接続端を設け、水質浄化用カートリッジを内蔵した把持部と、この把持部の先端に一体に形成され、原水と浄水とを選択する流路切換手段を内蔵し、シャワー吐出口を設けた頭部とを備え、この頭部にストレート吐出口、上記シャワー吐出口および第３の吐出口からの吐出を切換可能に形成した吐出切換弁を設け、上記水質浄化用カートリッジは、筒状に形成されて上記把持部内を外周側流路と中央空間部とに区画する水質浄化材を有することにより、上記外周側流路を通過して上記吐出切換弁へ連通可能な原水流路と、上記外周側流路から水質浄化材を透過して上記中央空間部へ流れ込み上記吐出切換弁へ連通可能な浄水流路とを形成し、原水吐出時には、上記原水が、浄水吐出時に上記水質浄化材の外周側表面に蓄積された目詰まりを引き起こす固形物質その他の蓄積物を洗い流すことを特徴とする。
【００１０】
そしてまた、請求項２に係る浄水機能付きシャワーヘッドは、前記吐出切換弁を、一定角度異なる位置でストレート吐出口、シャワー吐出口または第３の吐出口への各吐出路に接続する開口を設けた回動式の切換弁に形成したことを特徴とする。
【００１３】
【発明の実施の形態】
本発明における以下の実施の形態では、台所の流しに設ける蛇口に代えて浄水機能付きシャワーヘッドを設けた場合について説明する。
なお、この実施の形態は、発明の趣旨をより良く理解させるため具体的に説明するものであり、特に指定のない限り、発明内容を限定するものではない。
【００１４】
この実施の形態における台所は、図１に示すように、流し台１の上方に湯と水とを混合して流す混合水栓２の吐出口が位置するように配置し、この混合水栓２に接続されたフレキシブルなホース３の先端に浄水機能付きシャワーヘッド１０を取り付け、混合水栓２の下部で回動自在に設けられたシャワーヘッド支持部材（以下、ホルダ部という）４に着脱自在に係止して、ホルダ部４に浄水機能付きシャワーヘッド１０を係止したままの状態で、またはホルダ部４から浄水機能付きシャワーヘッド１０を取り外してホース３を必要に応じて引き出し曲げて使用することにより、水または湯または湯水混合水（以下、単に混合水という）を吐出したときに、流し台１の中央部周辺のみで混合水を使用し、または流し台１の中央部から周辺部に至るまで混合水を自在に供給できるようにする。
【００１５】
【実施例】
前記流し台１の混合水栓２に取り付けられる浄水機能付きシャワーヘッドにつき多数の実施例を以下に説明する。
〔第１実施例〕
〔構成〕
ここで用いられる浄水機能付きシャワーヘッド１０は、図２〜４の外観図に示すように、台所の流しで使用されるシャワーヘッドとして利用できるようにするため、混合水栓２のホース３に取付けできる端部を有する把持部１１と、この把持部１１のホース取付側とは反対側の端部にシャワー吐出口１２ａを一体的に設けた頭部１２とを備える。
【００１６】
把持部１１は、中間部で頭部１２側の筒部１１ａとホース取付側の筒部１１ｂとに分け、これらを着脱自在かつ一体的に組み合わせることができるようにする中継用ねじ部１１ｃを設け、この中継用ねじ部１１ｃの螺合を解除して筒部１１ａと筒部１１ｂを分離することにより、把持部１１の内部に水質浄化用カートリッジ（図５，６参照）１５を収容することができるようにし、そして、ホース取付側の端部にはホース取付ねじ１１ｄを設けた厚肉円筒状のホース接続部１１ｆを形成して、ホースとの着脱を容易にする。
【００１７】
頭部１２には、把持部１１側とは反対側の位置に流路切換用の押しボタン１３を突出し、押しボタン配設位置の略 90 度回動した位置に平面状のシャワー吐出口１２ａを形成し、そのシャワー吐出口１２ａの中央部にはストレート吐出口１２ｂを形成する。そして、押しボタン１３の配設位置の直近の下流側に、ストレート吐出口１２ｂからの吐出とシャワー吐出口１２ａからの吐出とを切り換える切換レバー１４を、シャワー吐出口１２ａを形成している面から突出配置されている。
【００１８】
浄水機能付きシャワーヘッド１０は、図５〜７に示すように、把持部１１の内部に水質浄化用カートリッジ１５を収容する。
この水質浄化用カートリッジ１５を収容した把持部１１では、水質浄化用カートリッジ１５の外周側流路２１を原水流路の一部とし、水質浄化用カートリッジ１５の中央空間部２２を浄水流路の一部として利用する。
【００１９】
水質浄化用カートリッジ１５は、中心軸と同心的に孔（中央空間部２２）を設けて円筒状に形成した水質浄化材１５ａと、その下流側に不織布、スポンジまたは網等からなるフィルタ１５ｂ，１５ｃに挟持されて配設された粒状あるいはペレット状の殺菌セラミック１５ｄとを、３つに分割したキャップ１５ｅ，１５ｆ，１５ｇによって形成される２つの空間にそれぞれ収容したものである。
【００２０】
そして、周壁にスリットを多数設けた有底円筒形状に形成したキャップ１５ｅと、円筒形状の中央部に流体通路となる孔を穿設した軸方向に垂直な面の水質浄化材支持壁を有して各端部に他のキャップ１５ｅ，１５ｇとの嵌合部を形成したキャップ１５ｆとにより設けられた空間に、水質浄化材１５ａを収容する。
【００２１】
また、キャップ１５ｆとは異径の２つの円筒を軸方向に垂直な壁面により接続し、２つの円筒のうち大径側の円筒にキャップ１５ｆとの嵌合部を形成し、小径側の円筒に頭部１２側に設けた（後述の）カートリッジ受け１１ｅとの嵌合部を形成したキャップ１５ｇにより設けられた、大径側の円筒の内部空間に、フィルタ１５ｂ，１５ｃに挟持された殺菌セラミック１５ｄを収容する。
【００２２】
収容される水質浄化材１５ａは、活性炭を主成分とし、円筒状に固めたもので、この円筒状の外周面と中心孔との間を混合水が透過する時に、水中に溶解した化学成分や浮遊している微細な固形物質が吸着または濾過される。
【００２３】
また、殺菌セラミック１５ｄは、リン酸カルシウムを母体として酸化亜鉛、モンモリロナイト等を混合して粒状あるいはペレット状に焼結したものに銀あるいは銅等を吸着したもので、その表面に水中の有害な細菌類を吸着して殺菌するとともに金属イオンを放出して水中の有害な細菌類を殺菌または滅菌し、水質を無害化する。
【００２４】
把持部１１の頭部１２側の筒部１１ａにおける内端部には、水質浄化用カートリッジ１５の先端部（キャップ１５ｇの小径側の端部）を差し込み固定する円筒状のカートリッジ受け１１ｅを突設する。
このカートリッジ受け１１ｅに水質浄化用カートリッジ１５のキャップ１５ｇの小径側の端部を差し込むことにより、水質浄化用カートリッジ１５が位置固定される。
【００２５】
キャップ１５ｇの小径側の端部には周面にＯリング１５ｈが周設され、カートリッジ受け１１ｅに差し込んだ場合にカートリッジ受け１１ｅの内周面に密接するＯリング１５ｈにより漏れが止められる。
【００２６】
そして、カートリッジ受け１１ｅの外周側の流路２３が、水質浄化用カートリッジ１５の外周側流路２１と連通して原水流路の一部として利用され、さらにカートリッジ受け１１ｅの内面側の流路２４が水質浄化用カートリッジ１５の中央空間部２２と殺菌セラミック１５ｄを介して連通することにより浄水流路の一部として利用される。
【００２７】
これにより、浄水吐出の場合には、把持部１１内に流入した混合水が、水質浄化用カートリッジ１５の外周側流路２１から水質浄化用カートリッジ１５の水質浄化材１５ａを通過して水質を浄化し、水質浄化材１５ａの中央空間部２２に流出して引き続きフィルタ１５ｂ、殺菌セラミック１５ｄ、フィルタ１５ｃを通過して殺菌または滅菌して水質を無害化し、その後、カートリッジ受け１１ｅの内面側の流路２４を介して頭部１２側に流出し、頭部１２から外部へ吐出する。
【００２８】
また、原水吐出の場合には、水質浄化用カートリッジ１５の外周側流路２１を通過し、カートリッジ受け１１ｅの外周側の流路２３を介して頭部１２側に流出し、頭部１２から外部へ吐出する。
この原水吐出の場合には、混合水が水質浄化用カートリッジ１５の外周側に形成された流路２１を通過するため、浄水吐出時に蓄積された水質浄化材表面に付着した目詰まりを引き起こすような微細な固形物質等を洗い流し、浄化吐出時に目詰りしにくくし、水質浄化材１５ａの浄化能力を高レベルに維持するとともに寿命を長くする。
特に、湯を原水吐出する場合には、湯温が高温であるほど、水質浄化材１５ａの主成分である活性炭から浄水吐出時に吸着したトリハロメタンや金属イオン等を放出して、効果的に除去することができ、活性炭の再生効果を高めることができる。
【００２９】
浄水機能付きシャワーヘッド１０は、図５，６，８〜１２に示すように、頭部１２に押しボタン１３と切換レバー１４とを突出している。
このうち、押しボタン１３は、原水流路（２１，２３）と浄水流路（２２，２４）とを各別に接続する遮断弁１６と遮断弁１７に連結し、これらの遮断弁１６，１７を流路切換弁（水質切換弁）として同時に操作できるようにしている。
【００３０】
この流路切換弁の下流側には、原水側では、遮断弁１６の下流側に混合水の流速を下げる空間として弁下流側空間１８を設け、その弁下流側空間１８の底面の中央部に弁下流側空間１８からシャワー吐出口１２ａとストレート吐出口１２ｂとのそれぞれの入口部に流出する集合通過部２５を設け、この集合通過部２５から僅かに隙間をあけた直近の下流にはストレート吐出口１２ｂの筒状に形成された入口部を形成し、集合通過部２５とストレート吐出口１２ｂの入口部との間の隙間に吐出切換弁２６の弁体２６ａを配置し、ストレート吐出口１２ｂの入口部の外周側をシャワー吐出口１２ａの入口部にする。
【００３１】
浄水側では、遮断弁１７の下流側に浄水吐出口１９への専用の弁下流側流路２０を形成して浄水と原水との流路を分離する。そして、浄水吐出口１９はシャワー吐出口１２ａの形成範囲内で、ストレート吐出口１２ｂの中心に対して吐出切換弁２６の回転軸設置位置から 90 度振った位置に設け、浄水吐出口１９から吐出した場合に、頭部１２の中心に位置した原水のストレート吐出とは位置が偏心しているため容易に浄化された混合水であることを区別できるようになる。
【００３２】
吐出切換弁２６は、集合通過部２５とストレート吐出口１２ｂの入口部との間に設けられた隙間に出入り自在に形成するとともに上面を浅い凹面に形成した弁体２６ａと、シャワー吐出口１２ａを貫通して軸回りに回動自在に支持されてシャワー吐出口１２ａの内部に位置する端部に弁体２６ａの取付端を固着するとともにシャワー吐出口１２ａの外部に位置する端部に切換レバー１４の取付端を固着した軸部２６ｂとからなる。
【００３３】
遮断弁１６と遮断弁１７とは、図５，８〜１０，１２に示すように、原水流路（２１，２３）と連通する遮断弁１６と浄水流路（２２，２４）と連通する遮断弁１７との間で、それぞれ弁座１６ａと弁座１７ａとの位置が、把持部１１の軸方向に対してずれており、押しボタン１３の押込み量によっていずれか一方の弁が閉じられるように配置される。
【００３４】
遮断弁１６は、図８，１０に示すように、押しボタン１３の浅い押込み量で弁閉となるように弁座１６ａの位置が定められ、その弁座１６ａを環状体に形成し、その環状体の孔部に上流側から鋼球等の硬い球形（ボール）に形成した弁体１６ｂを載せることにより弁閉にする。
この遮断弁１６では箱型の弁体支持部材１６ｃを形成して、その弁体支持部材１６ｃの内部にコイルスプリング１６ｄと弁体１６ｂとを収容し、コイルスプリング１６ｄの押圧力によって弁体１６ｂを弁座１６ａ側に押し付ける。
【００３５】
遮断弁１７は、図８，９，１２に示すように、押しボタン１３の深い押込み量で弁閉となるように弁座１７ａの位置が定められ、その弁座１７ａを環状体に形成し、その環状体の孔部に上流側から鋼球等の硬い球形（ボール）に形成した弁体１７ｂを載せることにより弁閉にする。
この遮断弁１７では箱型の弁体支持部材１７ｃを形成して、その弁体支持部材１７ｃの内部にコイルスプリング１７ｄと弁体１７ｂとを収容し、コイルスプリング１７ｄの押圧力によって弁体１７ｂを弁座１７ａ側に押し付ける。
【００３６】
図１０のように遮断弁１６が弁閉になる位置で止まっている場合には、押しボタン１３の押込み量が浅いため、遮断弁１７は、図９，１２のように弁体１７ｂが弁座１７ａのヘリの部分で止まっている状態になり、環状体に形成された弁座１７ａの孔部に達しないため、弁開の状態のままになる。
【００３７】
押しボタン１３と遮断弁１６および遮断弁１７との間には、図５，８，１３に示すように、弁体支持部材１６ｃと弁体支持部材１７ｃとに係合して弁体支持部材１６ｃと弁体支持部材１７ｃとを同時に押すことにより弁体１６ｂと弁体１７ｂとが同時に移動できるようにする２つのプッシュロッド３１，３１を一体に設けた切換軸１３ａと、この切換軸１３ａの移動距離を変えるためのカム機構を構成する３つの部品である切換リング１３ｂ、第１切換こま１３ｃ、第２切換こま１３ｄを組み合わせたものとを所定位置に嵌め合わせる。
【００３８】
切換軸１３ａは、２つのプッシュロッド３１，３１を両脇に配置し、中央部には弁側に底部を向けた有底円筒部材３２を配置し、２つの板状の支持部材３３，３３により有底円筒部材３２と各プッシュロッド３１，３１をそれぞれ所定の間隔で結合する。
【００３９】
各プッシュロッド３１，３１の支持部材３３を結合した部分の外側の端部には押しボタン１３の側面と係合するための爪部材３４，３４をそれぞれ端部に近接離間自在な弾力性を持たせて突出形成し、爪部材３４，３４を設けたそれぞれの端部には各爪部材３４，３４の突出方向に対して垂直な方向に、プッシュロッド３１，３１の移動方向に対するガイドをする案内部材３５，３５，３５，３５を突出形成する。
【００４０】
切換リング１３ｂは、図１４（Ａ），…，（Ｅ）に示すように、円筒部３６の内径側に溝３６ａを刻設し、円筒部３６の外周側に鍔部３７を設け、この鍔部３７の上下頂部に後述する切換カバー１３ｅと係合して位置固定する爪部３８，３８を突出する。
【００４１】
円筒部３６の内径側に刻設する溝３６ａは、軸方向に浅い溝３６１と軸方向に深い溝３６２とが交互に刻設され、その溝でない部分の切換軸側の端面には同一方向へ傾いた傾斜面３６ｂが形成され、当接する第１切換こま１３ｃに設けられたリブ４３の端部が、形成された傾斜面３６ｂの方向に従って移動し、誘導されて、刻設された浅い溝３６１と軸方向に深い溝３６２とのいずれかの溝に入り込むようになる。
【００４２】
第１切換こま１３ｃは、図１５（Ａ），…，（Ｅ）に示すように、細軸部４１と太軸部４２とに分かれ、太軸部４２に軸方向へ延びたリブ４３を周上等ピッチに３つ立設する。このリブ４３の切換リング側に位置する端部には、切換リング１３ｂの切換軸側の端面に設けられた傾斜面３６ｂと同じ方向に向いて傾斜する傾斜面４３ａを形成する。
【００４３】
第２切換こま１３ｄは、図１６（Ａ），…，（Ｄ）に示すように、一端には第１切換こま１３ｃの細軸部４１が挿入され、他端には押しボタン１３の内側中央部に突出した位置決め支持棒１３ｆが挿入される孔を有する円筒状の部材４４に、第１切換こま側に位置する端部には周上等ピッチに６個のリブ４５を立設し、リブ立設側の端部には第１切換こま１３ｃに設けたリブの傾斜面４３ａを形成した端部が当接する端面が傾斜した凹部４４ａを形成し、この凹部に当接した第１切換こま１３ｃのリブ４３がその傾斜した凹部４４ａの傾斜面に沿って移動することにより第１切換こま１３ｃが一定方向へ回転する。
【００４４】
切換カバー１３ｅは、図１３に示すように、プッシュロッド挿通孔４６，４６を穿設した板部４７の中間部に、切換軸１３ａの有底円筒部材３２を軸方向へ移動自在に内嵌するとともに切換リング１３ｂの円筒部３６を内嵌する筒部４８を形成し、この筒部４８の先端部の上下位置に切換リング１３ｂの爪３８，３８を係合する孔４９，４９を穿設し、筒部４８のプッシュロッド挿通孔４６，４６が穿設された側の側面には切換軸１３ａの支持部材３３，３３が軸方向へ移動自在に通過できるようにする切欠き部５０，５０を形成する。
【００４５】
頭部１２の内部を仕切る仕切部材１２ｃのプッシュロッド挿通孔５１（５１ａ，５１ｂ）を穿設した側壁と、切換カバー１３ｅのプッシュロッド挿通孔４６，４６を穿設した板部４７との間には、各プッシュロッド挿通孔４６，４６，５１，５１の穿設位置に合わせてＯリング５２，５２を介装するとともにその中間部にコイルスプリング５３を配置介装して、切換軸１３ａの有底円筒部３２の底部を仕切部材１２ｃの側壁から離間する方向へばね付勢する。
【００４６】
コイルスプリング５３の付勢力によって切換軸１３ａが仕切部材１２ｃの側壁から離間する方向へ移動する場合、切換リング１３ｂの深い溝３６ａ（３６２）に第１切換こま１３ｃのリブ４３が入って、移動を邪魔するものが何もない状態になれば、有底円筒部材３２に当接している第１切換こま１３ｃおよび第２切換こま１３ｄが、切換リング１３ｂの円筒部３６に刻設された深い溝３６ａ（３６２）内を切換軸１３ａの移動方向と同じ方向へ摺動し、切換軸１３ａに設けた有底円筒部材３２の開口側の端縁が切換リング１３ｂの鍔部３７に当接して止まるまで移動する。
【００４７】
流路切換弁下流側の流路は、図１３，１７〜２５に示す仕切部材１２ｃ、（第２の）仕切部材１２ｄ、浄水吐出口１９への弁下流側流路２０の一部を形成する浄水導管６５、シャワー吐出口１２ａとストレート吐出口１２ｂを形成するシャワープレート１２ｅおよびシャワープレート抑え１２ｆによって形成される。
【００４８】
（第１の）仕切部材１２ｃは、図１７，１８に示すように、頭部１２の吐出側と切換弁組込側との境界を規定する形状を有する仕切り５５を形成し、この仕切り５５の上部に各流路切換弁の入口側流路と接続する原水側の弁内空間５６、浄水側の弁内空間５７を形成し、仕切り５５の下側には弁下流側空間１８を形成する。また、仕切り５５の各弁内空間５６，５７を形成する位置には略中央部に弁座１６ａ，１７ａを形成する部材を嵌合する嵌合孔５８，５９を穿設する。この嵌合孔５８と嵌合孔５９とは、弁座１６ａと弁座１７ａとが押しボタン１３の押込み量によっていずれか一方の弁が閉じられるように、押し込み方向に位置をずらして穿設する。
【００４９】
弁座１６ａと弁座１７ａとは、図１９に示すように、同一の形状をした段違いのある階段状の断面を有する環状部材で、上面側は上面を弁体当接面に形成し、外形を仕切部材１２ｃの嵌合孔５８または嵌合孔５９に合わせた円周面を成形して嵌め込み容易に形成し、下面側は外形を嵌合孔５８または嵌合孔５９に合わせた円周面を成形するとともに内形を後述の（原水側の）弁座抑え６０または浄水導管６５との嵌合可能に成形する。
【００５０】
原水側の弁座抑え６０は、図２０に示すように、上面および外周に突出部がある厚肉の略矩形断面の環状体で、上面には弁座１６ａの下面側に形成された嵌合孔に嵌合可能に突出した環状突起６０ａを設け、外周には仕切部材１２ｃの嵌合孔５８に嵌合時のストッパとなる外方へ張り出したフランジを形成するフランジ状突出部６０ｂを設ける。
【００５１】
（第２の）仕切部材１２ｄは、図２１に示すように、外周縁に短い円筒状の環状部材６４，６４ｂを各面側に突設した円盤状の部材に形成し、円盤部の中央部に弁下流側空間１８からシャワー側空間１８ａまたはストレート吐出口１２ｂの入口部へ移行するための集合通過部２５を嵌合する嵌合孔６１を穿設し、中央部と周辺部との中間位置に浄水吐出口１９を有する浄水通路６２を設ける。浄水通路６２の弁下流側空間１８側に位置する端部には浄水導管６５を嵌合することができるように、浄水導管６５に嵌合できる径を有する円筒状の上端部６３を形成する。外周縁の下側の環状部材６４には外周面に雄ねじ６４ａを形成して後述のシャワープレート抑え１２ｆを螺合できるようにする。
【００５２】
弁下流側流路２０の一部を形成する浄水導管６５は、図２２，２３に示すように、上端には弁座１７ａの背面側の形状に合わせた上端部６５ａを形成して、弁体当接面を上方に向けた弁座１７ａを取り付けることができるようにし、下端には仕切部材１２ｄに形成された円筒状の上端部６３と内嵌できる径に形成された厚肉円筒状の下端部６５ｂを形成し、この下端部６５ｂの外周にはＯリング溝６５ｃを刻設して、Ｏリング溝６５ｃにＯリングをはめ込んで仕切部材１２ｄに設けられた円筒状の上端部６３に嵌合した場合にＯリングによって漏止めできるようにしている。
【００５３】
上端部６５ａと下端部６５ｂとの間は、ほぼ水平方向に向けて延設された断面矩形状の流路６５ｄによって連通し、この流路６５ｄの流路長さは浄水側の流路切換弁１７の中心位置から仕切部材１２ｄに設けられた円筒状の上端部６３の中心位置までの直線距離に等しくして、上端部６５ａを仕切り部材１２ｃの浄水側の嵌合孔５９にはめ込んだ後、この嵌合孔５９の中心を回動軸として浄水導管６５を回動させて、仕切部材１２ｄに設けられた円筒状の上端部６３の位置まで下端部６５ｂを移動して位置合わせをすることにより、仕切部材１２ｄ側と嵌め合わせることができるようにする。
【００５４】
シャワープレート１２ｅは、図２４に示すように、シャワー吐出口１２ａとストレート吐出口１２ｂとを穿設する。シャワープレート１２ｅにはストレート吐出口１２ｂに隣接して吐出切換弁２６の軸２６ｂを貫通させて軸支する軸孔６６を穿設し、この軸孔６６からストレート吐出口１２ｂを中心にして 90 度回動した位置には浄水吐出口１９を有する浄水通路６２の先端部を嵌合する嵌合孔６７を穿設する。そして、シャワープレート１２ｅの面におけるストレート吐出口１２ｂ、軸孔６６、嵌合孔６７によって占められる面の残りの部分には、シャワー吐出孔１２ｂとなる小孔を多数個につき穿設する。
【００５５】
シャワープレート抑え１２ｆは、図２５に示すように、下端に内側に突出した張出部６８を設けた断面が略板状のリング部材で、頭部の周面下端部からシャワー面の周端部を形成する外形に成形し、内周面側には雌ねじ６９を形成して、仕切部材１２ｄに設けた雄ねじ６４ａに螺合できるようにする。
【００５６】
〔作用効果〕
このように構成した実施の形態においては、頭部１２に組み込まれている押しボタン１３を操作することにより、押しボタン１３が頭部１２より突き出ている状態（浅い押込量）では浄化された混合水が流出し、押しボタン１３が頭部１２に入り込んで突き出ている量が少なくなっている状態（深い押込量）では原水が流出する。
【００５７】
まず、図８〜１０，１２に示すように浅い押込量で浄化された混合水が流出しているものとする時、図２６〜２８に示すように深い押込量になるように押しボタン１３を押すと、押しボタン１３に当接している第２切換こま１３ｄが第１切換こま１３ｃを押し、第１切換こま１３ｃから切換軸１３ａへ押圧力を伝達して、コイルスプリング５３の付勢力に抗して切換軸１３ａを仕切部材１２ｃの側壁に近接する方向へ移動する。
【００５８】
この時、第１切換こま１３ｃが切換リング１３ｂの溝を摺動して、その溝から外れるまで移動すると、第２切換こま１３ｄに押されている第１切換こま１３ｃは第２切換こま１３ｄと第１切換こま１３ｃとの当接部の形状に従って密着する向きに変わるように動いて結果として回転し、第１切換こま１３ｃと切換リング１３ｂの端面３６ｂとの相対的な位置を変更するとともに、遮断弁１６を開き、遮断弁１７を閉じて、原水の流出に切り換える。
【００５９】
遮断弁１６が開き、遮断弁１７が閉じて、コイルスプリング５３の付勢力によって遊び分だけ切換軸１３ａを戻し、第１切換こま１３ｃに設けられたリブの端部が切換リング１３ｂに刻設された浅い溝側に当接して位置固定すると、流出する混合水が原水になる。
【００６０】
再度、押しボタン１３を押して、押しボタン１３に当接している第２切換こま１３ｄから第１切換こま１３ｃ、さらに切換軸１３ａへ押圧力を伝達することにより、コイルスプリング５３の付勢力に抗して切換軸１３ａを仕切部材１２ｃの側壁に近接する方向へ移動させると、第１切換こま１３ｃに設けられたリブの端部が切換リング１３ｂに刻設された浅い溝３６ａ（３６１）との係合を外し、第２切換こま１３ｄに押されている第１切換こま１３ｃが、第２切換こま１３ｄと第１切換こま１３ｃとの当接部の形状に従って密着する向きに変わるように動き、結果として回転して、第１切換こま１３ｃと切換リング１３ｂの端面３６ｂとの相対的な位置を変更する。
【００６１】
これにより、図８〜１０に示すように、切換リング１３ｂの軸方向に深い溝３６ａ（３６２）に第１切換こま１３ｃに設けられたリブ４３が入り、コイルスプリング５３の付勢力によって、第１切換こま１３ｃに設けられたリブ４３を切換リング１３ｂの溝に沿って仕切部材１２ｃの側壁から離間する方向へ摺動させることになり、第１切換こま１３ｃに当接している切換軸１３ａを仕切部材１２ｃの側壁から離間する方向へ移動させて、遮断弁１６を閉じ、遮断弁１７を開いて、浄水の流出に切り換える。
【００６２】
浄水流出時は、図１２に示すように、遮断弁１７の弁座１７ａを通過して弁下流側流路２０へ流出し、その弁下流側流路２０から浄水導管６５を介して浄水流路６２の下端に形成された浄水吐出口１９から吐出するようになる。
また、原水流出時には、図２６〜２８に示すように、遮断弁１６の弁座１６ａを通過して弁下流側空間１８に流出し、この弁下流側空間１８から集合通過部２５を介して切換レバー１４により指定されたシャワー吐出またはストレート吐出をする。
【００６３】
原水の吐出時において、シャワー吐出している場合に、押しボタン１３の操作とは独立に、切換レバー１４を操作して軸部２６ｂを中心に弁体２６ａを回動すると、弁体２６ａがストレート吐出口１２ｂの入口部から外れ、集合通過部２５からでる混合水がストレート吐出口１２ｂの入口部へ流入し、ストレート吐出するようになる。
【００６４】
また、原水の吐出時にストレート吐出している場合に、切換レバー１４を反対方向へ操作して、軸部２６ｂを中心に逆回りに弁体２６ａを回動すると、弁体２６ａがストレート吐出口１２ｂの入口部に入り、集合通過部２５からでる混合水がストレート吐出口１２ｂの入口部へ流入することを阻止してシャワー吐出口１２ａ側へ流路を変更し、シャワー側空間１８ａに流入してシャワー吐出口１２ａからシャワー吐出するようになる。
【００６５】
このような第１実施例では、浄水吐出口１９がシャワー吐出口形成領域内に原水吐出流路とは別個に形成されているため、原水吐出とは容易に識別できるとともに浄水吐出時にはシャワー吐出とストレート吐出との切換を行うことなく使用できて操作が容易となり、識別性及び操作性を向上させることができる。
【００６６】
また、水質を切り換えるための遮断弁１６，１７からなる流路切換弁に係る大きさの制約を頭部１２に組込可能な範囲まで広げることができて、流路切換弁の大きさの制約が大幅に緩和でき、頭部１２側で流路切換弁の操作が可能になるため操作性が良くなり、また、頭部１２と把持部１１との重量配分がバランス良く配分できて、シャワーヘッド取扱上もバランスの良い、形状・構造にすることができる。
【００６７】
把持部１１に水質浄化用カートリッジ１５を内蔵することにより、水質浄化用カートリッジ１５の外周側に原水流路の一部が形成でき、この原水流路から水質浄化用カートリッジ１５に設けられた水質浄化材１５ａを介して中心部に形成された中央空間部２２に至る浄水流路の一部が形成できて、流路構成が簡素化できるとともにコンパクトにでき、把持部１１の構造が単純になって水質浄化材１５ａの内容物をより多く収納できるようになる。
【００６８】
水質浄化材１５ａよりも上流側の流路が原水と浄水との共用流路となり、浄水吐出時に蓄積された目詰りを引き起こすような固形物質その他の蓄積物を原水吐出時に洗い流すことができ、目詰りしにくくするとともに水質浄化材１５ａの寿命を長くすることができる。
【００６９】
把持部１１には水質浄化用カートリッジ１５が内蔵され、頭部１２には流路切換弁が組み込まれて、流路が簡潔にでき、重量配分が良く、取扱上、非常にバランスの良いシャワーヘッドとなり、軽量且つ安価となる。
【００７０】
流路切換弁は、原水用の遮断弁１６と浄水用の遮断弁１７とが同じ押しボタン１３によって交互に流路を遮断する交互切換式遮断弁となっているため、頭部１２に突出した押しボタン１３を押すことにより、浄水と原水とを切り換えて使用することができ、操作性が向上する。
【００７１】
また、交互切換式遮断弁の原水用の遮断弁１６と浄水用の遮断弁１７とがそれぞれ球状弁体１６ｂ，１７ｂであるため、弁閉時には、球状弁体１６ｂ，１７ｂに加えられる水圧が、コイルスプリング１６ｄ，１７ｄの付勢力とともに、球状弁体１６ｂ，１７ｂを弁座１６ａ，１７ａに押し付けるように作用して、確実にシールすることができるようになる。
【００７２】
吐出切換弁２６が、流路切換弁のうち原水側の遮断弁１６の下流側に設けられた流路中に、レバー操作の遮断弁が形成されているため、原水の吐出では、シャワー吐出とストレート吐出とのどちらでも容易に選択でき、高い利便性を維持することができる。
なお、流路切換弁への流入路を変更して、遮断弁１６側を浄水側とし、遮断弁１７を原水側とすれば、浄水側にシャワー吐出とストレート吐出との切換可能な流路を構成できる。
また、この実施例では、流路切換弁に２つの遮断弁１６，１７を具備した構成にしているが、１つの遮断弁で流路の切換を行うように構成しても良い。
この浄水機能付きシャワーヘッド１０は、台所の他、洗面所や風呂場等でも用いることができ、汎用性が非常に高いものとなる。
【００７３】
〔第２実施例〕
〔構成〕
第１実施例の浄水機能付きシャワーヘッド１０は混合水が浄化後に流路切換弁の浄化側の遮断弁に達するように流路を構成しているが、この第２実施例の浄水機能付きシャワーヘッド２００では、図２９，３０に示すように、流路切換弁の浄化側の遮断弁を通過してから水質浄化用カートリッジの水質浄化材を透過して水質を浄化するように構成している点が異なる。
以下の説明では、流路の構成に係る部材以外の個々の部材については第１実施例と同じ構成にして頭部に設けた押しボタンによって浄水と原水とを切り換えるシャワーヘッドを形成するため、第１実施例における部材と同じ構成の部材については同じ番号または数字の下２桁を合わせるように付して説明を省略する。
【００７４】
頭部１２側から突出している筒部１１ａの内側に、所定の流路幅をあけて同心的に筒部１１ａよりも長い内筒部２０１を形成し、そして、内筒部２０１の内側には、カートリッジ受け２１１を先端部に形成して水質浄化用カートリッジ１５をその頭部側の端部を内嵌して取り付けられるようにする。
【００７５】
内筒部２０１の長さは、カートリッジ受け２１１に取り付けられた水質浄化用カートリッジ１５の上流側の端部に達するまでの長さを有し、水質浄化用カートリッジ１５がカートリッジ受け２１１に装着されたときに内筒部２０１の先端と水質浄化用カートリッジ１５の上流側の端部が当接して密閉できるように形成して、カートリッジ装着時には内筒部２０１の外側に原水流路２０２、内筒部２０１の内側にカートリッジ外周流路２０３を形成できるようにする。
【００７６】
この場合に用いられる水質浄化用カートリッジ１５は、頭部１２側に配置されたカートリッジ受け２１１に嵌合するキャップ１５ｇを第１実施例のキャップ１５ｇと同じ形状に形成したものを用い、把持部１１の原水流入側に配置されるキャップ１５ｐを内筒部２０１の先端部に内嵌するとともに先端面に当接する厚肉部を有する有底円筒形状に形成し、キャップ１５ｐの厚肉部を有するキャップ端部には内筒部２０１に内嵌する部分の外周面にＯリング溝１５ｑを刻設し、このＯリング溝１５ｑにＯリング１５ｒを嵌着して、内筒部２０１への内嵌時に内筒部２０１の先端部内面にＯリング１５ｒを当接させて水漏れを防止する。
【００７７】
そして、頭部側では、図３０〜３５に示すように、遮断弁１６，１７の上流に共通の弁内空間２１０を設け、遮断弁１６の下流側には原水吐出側の流路となる弁下流側空間１８を形成するとともに、遮断弁１７の下流側には弁下流側空間１８と隔離された把持部１１側へ接続される流路２０４を形成し、遮断弁１７の下流側の流路２０４とカートリッジ外周流路２０３との間に開口形状が略矩形の開口２０４ａを設け、この開口２０４ａの外方が把持部１１側に形成された内筒部２０１のカートリッジ外周流路２０３の頭部側に位置する端部となり、遮断弁下流側に位置するカートリッジ上流側の流路を形成する。
【００７８】
カートリッジ受け２１１の内面側に形成された浄水流路２０６と頭部側の浄水流路２０８との間にも開口２０７，２０８ａを設け、カートリッジ受け２１１の内側からその基部に至る把持部側の浄水流路２０６と、開口２０７，２０８ａから浄水吐出口２１９に至る頭部側の浄水流路２０８とが連通して、水質浄化用カートリッジ１５を通過し浄化されて出てきた混合水のカートリッジ下流側における専用流路を形成する。
【００７９】
このため、水質浄化用カートリッジ１５を内筒部２０１に挿通し、先端のキャップ１５ｇをカートリッジ受け２１１に内嵌し、キャップ１５ｐのキャップ端部が内筒部２０１の先端に当接して位置固定すると、内筒部２０１と水質浄化用カートリッジ１５との間に形成される間隙によって、遮断弁１７の下流側に原水流路としてのカートリッジ外周流路２０３が形成されるから、把持部１１のホース接続部１１ｆから原水である混合水が流入すると、内筒部２０１の外周側に形成された原水流路２０２を通過して遮断弁１６，１７の上流に設けられた共通の弁内空間２１０に流入し、そして流路切換弁の遮断弁１７を通過した後の原水流路であるカートリッジ外周流路２０３に流入して、原水がカートリッジ外周流路２０３から水質浄化用カートリッジ１５を通過して中央空間部２２に流出するまでの間に浄化され、浄化された混合水がカートリッジ下流側の専用流路である浄水流路２０６、開口２０７，２０８ａおよび浄水流路２０８を通過して浄水吐出口２１９から吐出するようになる。
【００８０】
流路切換弁の下流側に水質浄化用カートリッジを配置した浄水機能付きシャワーヘッドでは、図３１〜３５に示すように、頭部１２に組み込まれた流路切換弁の１６，１７の弁座１６ａ，１７ａを配置するとともに流路切換弁前後の流路を仕切るための（第１の）仕切部材２１２と、弁座１６ａを支持するとともに浄水流路２０８と弁下流側空間１８との間を仕切る（第２の）仕切部材２１３と、原水側の遮断弁１６の下流側の流路である弁下流側空間１８と弁下流側空間１８から流入してシャワープレート２１６から吐出するための入口部となるシャワー側空間２１４との間を仕切る（第３の）仕切部材２１５とを配設して、流路切換弁下流側における水質浄化用カートリッジ前後の頭部側流路を形成する。
【００８１】
このうち、把持部１１の筒部１１ａを一体的に組み合わせた頭部１２では、図３６〜３７に示すように、頭部１２側から突出している筒部１１ａの内側に、所定の流路幅をあけて同心的に筒部１１ａよりも長い内筒部２０１を形成し、その内筒部２０１の内側には、カートリッジ受け１１ｅを先端部に形成して水質浄化用カートリッジ１５をその頭部側の端部を内嵌して取り付けられるようにするとともに、カートリッジ受け１１ｅの内面側に浄水流路２０６を形成して、水質浄化用カートリッジ１５を通過して浄化された混合水のカートリッジ下流側における浄水専用流路を形成する。
【００８２】
そして、この頭部１２の内面側には、流路切換弁等を収容する空間を有し、頂部が曲面に形成されるとともに主要部が略円筒状に形成された頭部外皮１２ｇに、円筒中心に対して筒部１１ａの反対側の位置に押しボタン１３が貫通する略矩形状の孔１２ｈを穿設し、頭部外皮１２ｇの頂部曲面の裏側には孔１２ｈに接する位置から流路切換弁の弁入口側の隔壁１２ｊまでに至る直線状に形成した複数のリブ１２ｉ，１２ｉを突設し、流路切換弁の弁箱の上部を形成する隔壁１２ｊにより形成された弁内空間２１０には頂部曲面の裏側に弁体支持部材１６ｃ，１７ｃの上面を当接して移動時の案内部材として機能する複数本のリブ１２ｌ，…，１２ｌを突設する。
【００８３】
（第１の）仕切部材２１２は、図３８，３９に示すように、頭部１２に組み込まれた流路切換弁の１６，１７の両弁座１６ａ，１７ａを取り付けるとともに流路切換弁前後の流路を仕切る板材２１２ａと、この板材２１２ａの上面外周に立設した弁内空間２１０の略下半分の高さを占める隔壁を形成する枠体（弁ケース形成枠）２１２ｂを形成し、板材２１２ａの下面外周には流路２０４と弁下流側空間１８とを確保する段違いの凹部を形成する隔壁を下方に立設する枠体（流路枠）２１２ｃを形成する。
【００８４】
そして、板材２１２ａの弁座１６ａ，１７ａを形成する位置には弁座１６ａ，１７ａを形成する部材を嵌合する嵌合孔２１２ｄ，２１２ｅを穿設する。その嵌合孔穿設位置の下側には弁座抑え６０または（第２の）仕切部材２１３に設けられた弁座抑え２１３ｃ（図４０参照）を嵌合するリング状嵌合部２１２ｆ，２１２ｇを垂下する。
各嵌合孔２１２ｄ，２１２ｅは、弁座１６ａと弁座１７ａとが押しボタン１３の押込み量によっていずれか一方の弁が閉じられるように、押し込み方向にずらして穿設する。
【００８５】
（第２の）仕切部材２１３は、図４０に示すように、円盤状に形成された板材２１３ａに、一面側には中央部に必要な孔２１３ｂを穿設した弁座抑え２１３ｃを突設し、他面側には浄水流路２０８の上端を封鎖する蓋となる嵌合端２１３ｄを突設する。
【００８６】
（第３の）仕切部材２１５は、図４１に示すように、外周縁に短い環状部材６４，２１５ｂを突設した円盤状の部材に形成され、円盤部２１５ａの中央部に弁下流側空間１８からシャワー側空間２１４あるいはストレート吐出口１２ｂへ流出するための集合通過部２５を嵌合する嵌合孔６１を穿設し、中央部と周辺部との中間位置に浄水吐出口２１９を有する円筒状の浄水通路６２を設ける。
浄水通路６２の上端部は仕切部材２１３の嵌合端２１３ｄを嵌め合わせることができるように寸法を合わせて形成する。外周縁の下側の環状部材６４には外周面に雄ねじ６４ａを形成してシャワープレート抑え１２ｆを螺合できるようにする（図３２，３５参照）。
【００８７】
シャワープレート２１６は、図４２に示すように、円盤状の板材２１６ａの中央部に円筒状のストレート吐出口１２ｂを形成し、ストレート吐出口１２ｂに隣接した外周寄りの位置に吐出切換弁２６の軸２６ｂを貫通させる軸孔２１６ｂを穿設し、この軸孔２１６ｂから１８０度回動した位置には浄水通路６２の浄水吐出口２１９を形成した端部を嵌合する嵌合孔２１６ｃを穿設し、これらが占める領域を除いた板材２１６ａにはシャワー吐出口１２ａとなる小孔を多数個につき穿設する。
【００８８】
〔作用効果〕
このような構成により、ホース接続部１１ｆから原水が流入すると、内筒部２０１の外周側に形成された原水流路２０２を通過して遮断弁１６，１７の上流に設けられた共通の弁内空間２１０に流入し、押しボタン１３の位置が浅い押込量の位置か深い押込量の位置かに従い遮断弁１６，１７のいずれか一方が開放状態となり、原水吐出か浄水吐出かに分かれる。
【００８９】
浄水吐出の場合には、図３１〜３５に示すように、押しボタン１３の位置が浅い押込量の位置で、混合水は遮断弁１７の弁座１７ａを通過して下流側の流路２０４から開口２０４ａを介してカートリッジ外周流路２０３に流入し、水質浄化用カートリッジ１５の水質浄化材１５ａを透過して中央空間部２２に流出し、この中央空間部２２からフィルタ１５ｂと殺菌セラミック１５ｄとフィルタ１５ｃとを透過し、さらにカートリッジ受け２１１内の浄水流路２０６を通過して開口２０７，２０８ａを介して浄水流路２０８に流出し、浄水吐出口２１９から吐出する。
【００９０】
また、原水の吐出時には、図４３〜４５に示すように、押しボタン１３の位置が深い押込量の位置で、混合水は遮断弁１６の弁座１６ａを通過して弁下流側空間１８に流出し、この弁下流側空間１８から集合通過部２５を介して吐出切換弁２６が選択しているシャワー吐出口１２ａまたはストレート吐出口１２ｂから原水のまま吐出する。
【００９１】
原水吐出時では、シャワー吐出している場合に、押しボタン１３の操作とは独立に、切換レバー１４を操作して軸部２６ｂを中心に弁体２６ａを回動すると、弁体２６ａがストレート吐出口１２ｂの入口部から外れ、原水が集合通過部２５からストレート吐出口１２ｂの入口部へ流入して、ストレート吐出するようになる。
【００９２】
また、ストレート吐出している場合に、切換レバー１４を反対方向へ操作して、軸部２６ｂを中心に逆回りに弁体２６ａを回動すると、弁体２６ａがストレート吐出口１２ｂの入口部に入り、原水が集合通過部２５からストレート吐出口１２ｂの入口部へ流入することを阻止して、シャワー吐出口１２ａ側へ流路を変更し、シャワー側空間２１４に流出してシャワー吐出するようになる。
【００９３】
このような第２実施例では、遮断弁１７を経由してから水質浄化用カートリッジ１５に至る流路を有するシャワーヘッドを形成でき、流路切換弁の各遮断弁１６，１７を水質浄化用カートリッジ１５の上流側に設けることができるようになるため、第１実施例と第２実施例とにより、流路切換弁は水質浄化用カートリッジ１５の上流側と下流側のどちらにでも設けることができるようになる。
【００９４】
これらは共に、頭部１２に設けられた押しボタン１３の操作によって、各流路切換弁１６，１７の開閉が交互に切り換えられ、浄化された混合水か原水かのいずれであっても容易に選択することができ、さらに、原水の場合はストレート吐出とシャワー吐出とを容易に選択することができる。
なお、流路切換弁への流入路を変更して、遮断弁１６側を浄水側とし、遮断弁１７を原水側とすれば、浄水側にシャワー吐出とストレート吐出との切換可能な流路を構成できる。
【００９５】
〔第３実施例〕
〔構成〕
第１実施例の浄水機能付きシャワーヘッド１０は混合水が浄化後に流路切換弁の浄化側の遮断弁を経由してシャワー吐出口形成領域内からストレート吐出するように構成したが、この第３実施例の浄水機能付きシャワーヘッド３００では、図４６，４７に示すように、浄化後の混合水がシャワー吐出口形成領域の外部からストレート吐出するように構成している点が異なる。
以下の説明では、流路の構成に係る部材以外の個々の部材については第１実施例と同じ構成にして、頭部に設けた押しボタンによって浄水と原水とを切り換え、切換レバーによってシャワー吐出とストレート吐出とを切り換えるシャワーヘッドを形成するため、第１実施例における部材と同じ構成の部材については同じ番号または数字の下２桁を合わせるように付して説明を省略する。
【００９６】
この浄水機能付きシャワーヘッド３００は、図４６〜４７に示すように、頭部１２に押しボタン１３と切換レバー１４とを突出し、このうち、押しボタン１３は、原水流路と浄水流路とを各別に接続する遮断弁１６と遮断弁１７に連結し、これらの遮断弁１６，１７を流路切換弁（水質切換弁）として同時に操作できるようにしている。
【００９７】
この流路切換弁の下流側には、原水側では、図４７，５０に示すように、遮断弁１６の下流側に弁下流側空間１８を設け、その弁下流側空間１８の底面の中央部にシャワー吐出口１２ａとストレート吐出口１２ｂとのそれぞれの入口部に流出する集合通過部２５を設け、この集合通過部２５から僅かに隙間をあけた直近の下流にはストレート吐出口１２ｂの筒状に形成された入口部を形成し、集合通過部２５とストレート吐出口１２ｂの入口部との間の隙間に吐出切換弁２６の弁体２６ａを配置し、ストレート吐出口１２ｂの外周側にシャワー吐出口１２ａを配置する。
【００９８】
浄水側では、図４８〜４９，５１，５２に示すように、遮断弁１７の下流側に浄水吐出口３１９への専用の弁下流側流路２０，３２０を形成して浄水と原水との流路を分離する。そして、浄水吐出口３１９はシャワー吐出口形成範囲の外部で、ストレート吐出口１２ｂを中心として吐出切換弁２６の回転軸設置位置から 180度振った位置（正反対の位置）の把持部１１側に突設し、浄水吐出口３１９から吐出させた場合には、把持部１１の頭部１２に近接した位置から吐出して、原水のストレート吐出よりも位置が奥に位置しているため容易に浄化された混合水であることを区別できるようになる。
【００９９】
流路切換弁下流側に形成される流路は、図４６〜５２に示すように、把持部１１の筒部１１ａを突出した頭部１２、および頭部１２に組み込まれる仕切部材３１２、（第２の）仕切部材３１３、浄水吐出口３１９への弁下流側流路２０の一部を形成する浄水導管６５、シャワー吐出口１２ａおよびストレート吐出口１２ｂを形成するシャワープレート３１６ならびにシャワープレート抑え１２ｆによって形成される。
【０１００】
このうち、頭部１２は、図５３〜５６に示すように、把持部側には把持部１１の筒部１１ａを突出し、その突出した筒部１１ａの内側にカートリッジ受け１１ｅを突出し、吐出側には流路切換弁等を収容する頂部が曲面に形成され主要部が円筒状に形成された頭部外皮１２ｇに、円筒中心に対して筒部１１ａの反対側の位置に押しボタン１３が貫通する孔１２ｈを穿設し、頭部外皮１２ｇの頂部曲面の裏側には孔１２ｈに接する位置から流路切換弁の弁入口側の隔壁１２ｊまでに至る直線状に形成した複数のリブ１２ｉ，１２ｉを突設し、流路切換弁の弁箱の上部を形成する隔壁１２ｊの中央部には原水と浄水とを区分する隔壁１２ｋを立設し、隔壁１２ｊと隔壁１２ｋとにより形成された弁内空間５６，５７には頂部曲面の裏側に弁体支持部材１６ｃ，１７ｃの上面を当接して移動時の案内部材として機能する複数本のリブ１２ｌ，…，１２ｌを突設する。
【０１０１】
頭部１２から突出した筒部１１ａの根元には、浄水吐出口３１９をシャワー吐出口１２ａおよびストレート吐出口１２ｂと同じ方向に向けて開口し、浄水吐出口３１９には頭部１２に形成された仕切部材３１２，３１３を収容する空間の内周面の把持部１１側に位置する所定箇所から浄水吐出口３１９までの浄水流路３１９ａを穿設する。
【０１０２】
（第１の）仕切部材３１２は、図５７，５８に示すように、頭部１２の吐出側と切換弁組込側との境界を規定する形状を有する仕切り５５を形成し、この仕切り５５の上部に各流路切換弁の入口側流路と接続する原水側弁内空間５６、浄水側弁内空間５７を形成し、仕切り５５の下側には弁下流側空間１８を形成する。
また、仕切り５５の各弁内空間５６，５７を形成する位置には略中央部に弁座１６ａ，１７ａを形成する部材を嵌合する嵌合孔５８，５９を穿設する。この嵌合孔５８と嵌合孔５９とは、弁座１６ａと弁座１７ａとが押しボタン１３の押込み量によっていずれか一方の弁が閉じられるように、押し込み方向にずらして穿設する。
【０１０３】
（第２の）仕切部材３１３は、図５９に示すように、上側の外周端部に低い筒状に形成した流路形成部材３１３ａと下側の外周縁に環状部材６４を設けた円盤状の部材に形成し、円盤部の中央部に弁下流側空間１８からシャワー側空間３１４またはストレート吐出口１２ｂへ移行するための集合通過部２５を嵌合する嵌合孔６１を穿設し、嵌合孔６１の外周側に浄水導管６５の下流側の端部を挿入する筒状に形成した浄水導管３１３ｂをその側面の一部が流路形成部材３１３ａと一体化するように立設し、その浄水導管３１３ｂと流路形成部材３１３ａとの一体化した箇所には浄水導管３１３ｂの内部である弁下流側流路２０から流路形成部材３１３ａの外周側に形成される浄水流路３２０へ抜け出るための開口３１３ｃを設ける。下側の外周縁に形成された環状部材６４には外周面に雄ねじ６４ａを形成してシャワープレート抑え１２ｆを螺合できるようにする（図４９，５１参照）。
【０１０４】
シャワープレート３１６は、図６０に示すように、シャワー吐出口１２ａとストレート吐出口１２ｂとを形成した一枚の円盤状の部材である。シャワープレート３１６には中央部にストレート吐出口１２ｂとなる孔を穿設し、このストレート吐出口１２ｂに隣接して吐出切換弁２６の軸２６ｂを貫通させて軸支する軸孔６６を穿設する。そして、シャワープレート３１６の面におけるストレート吐出口１２ｂと軸孔６６とによって占められる箇所の残りの面には、シャワー吐出口１２ａとなる小孔を多数個につき穿設する。

〔作用効果〕
このように構成した第３実施例においては、頭部１２に組み込まれている押しボタン１３を操作することにより、押しボタン１３が頭部１２より突き出ている状態（浅い押込量）では浄化された混合水が浄水吐出口３１９から流出し、押しボタン１３が頭部１２に入り込んで突き出ている量が少なくなっている状態（深い押込量）では、切換レバー１４を操作して吐出切換弁２６をシャワー吐出かストレート吐出かを選択することによって、原水がシャワー吐出口１２ａまたはストレート吐出口１２ｂから流出する。
【０１０６】
まず、押しボタン１３が浅い押込量で、原水側の遮断弁１６が閉じ、浄水側の遮断弁１７が開いており浄化された混合水が流出している時、押しボタン１３を深い押込量になるように押し込むと、遮断弁１６が開き、遮断弁１７が閉じて、原水の吐出に切り換わる。この状態から再度押しボタン１３を押して、押しボタン１３を浅い押込量に変えると、遮断弁１６が閉じ、遮断弁１７が開いて、浄水の吐出に切り換わる。
【０１０７】
浄水の吐出時は、遮断弁１７の弁座１７ａを通過して浄水導管６５および仕切部材３１３の流路形成部材３１３ａにより形成される弁下流側流路２０へ流出し、開口３１３ｃを介して原水側の弁下流側空間１８の外周に沿って形成された浄水側の弁下流側流路３２０に流出し、この弁下流側流路３２０から浄水流路３１９ａを介して頭部１２から突出した筒部１１ａに突設された浄水吐出口３１９から吐出する。
【０１０８】
また、原水の吐出時には、第１実施例の場合と同様に、遮断弁１６の弁座１６ａを通過して弁下流側空間１８に流出し、この弁下流側空間１８から集合通過部２５を介して切換レバー１４により選定されたシャワー吐出またはストレート吐出をする。
【０１０９】
この場合において、シャワー吐出している場合に、押しボタン１３の操作とは独立に、切換レバー１４を操作して軸部２６ｂを中心に弁体２６ａを回動すると、弁体２６ａがストレート吐出口１２ｂの入口部から外れ、集合通過部２５から流出する原水がストレート吐出口１２ｂの入口部へ流入し、ストレート吐出するようになる。
【０１１０】
さらに、ストレート吐出している場合に、切換レバー１４を反対方向へ操作して、軸部２６ｂを中心に逆回りに弁体２６ａを回動すると、弁体２６ａがストレート吐出口１２ｂの入口部に入り、集合通過部２５から流出する原水をストレート吐出口１２ｂの入口部へ流入することを阻止して、シャワー側空間３１４に流路を変更し、シャワー側空間３１４からシャワー吐出口１２ａを介してシャワー吐出するようになる。
【０１１１】
このような第３実施例では、浄水吐出口３１９が把持部１１の筒部１１ａに設けられているため、浄水吐出と原水吐出との区別が容易にでき、また、浄水吐出では吐出切換を行うことなく吐出できて操作性を向上させたことによって、識別性、視認性および操作性が向上する。
【０１１２】
さらに、流路切換弁の原水用の遮断弁１６と浄水用の遮断弁１７とが同じ押しボタン１３によって交互に流路を遮断する交互切換式遮断弁となっているため、頭部１２に突出した押しボタン１３を押すことにより、浄水と原水とを切り換えて使用することができ、操作性を一層向上させることができる。
【０１１３】
また、交互切換式遮断弁の原水用の遮断弁１６と浄水用の遮断弁１７とがそれぞれ球状弁体１６ｂ，１７ｂであるため、弁閉時には、球状弁体１６ｂ，１７ｂに加えられる水圧が、コイルスプリング１６ｄ，１７ｄの付勢力とともに、球状弁体１６ｂ，１７ｂを弁座１６ａ，１７ａに押し付けるように作用して、確実にシールすることができる。
【０１１４】
吐出切換弁２６が、流路切換弁のうち原水側の遮断弁１６の下流側に設けられた流路中に、レバー操作の遮断弁が形成されているため、原水側の遮断弁１６が開いた場合に、シャワー吐出とストレート吐出とのどちらかを選択でき、原水の使用に関して高い利便性を与えることができる。
なお、流路切換弁への流入路を変更して、遮断弁１６を浄水側とし、遮断弁１７を原水側とすると、浄水側をシャワー吐出とストレート吐出との切換可能な構成に形成できる。
【０１１５】
〔第４実施例〕
〔構成〕
第２実施例の浄水機能付きシャワーヘッド２００は、混合水が流路切換弁の浄水側の遮断弁を通過した後に水質浄化用カートリッジの水質浄化材を透過して水質浄化され、シャワー吐出口形成領域内からストレート吐出するように流路を構成したが、この第４実施例の浄水機能付きシャワーヘッド４００では、図６１，６２に示すように、浄水側の遮断弁を通過した後に水質浄化し、浄化後の吐出をシャワー吐出口形成領域の外部からストレート吐出するように構成している点が異なる。
以下の説明では、流路の構成に係る部材以外の個々の部材については第２実施例と同じ構成にして頭部に設けた押しボタンによって浄水と原水とを切り換えるシャワーヘッドを形成するため、第２実施例における部材と同じ構成の部材については同じ番号または数字の下２桁を合わせるように付して説明を省略する。
【０１１６】
頭部１２側から突出している筒部１１ａの内側に、所定の流路幅をあけて同心的に筒部１１ａよりも長い内筒部４０１を形成し、そして、内筒部４０１の内側には、カートリッジ受け４１１を先端部に形成して水質浄化用カートリッジ１５をその頭部側の端部を内嵌して取り付けられるようにする。
【０１１７】
内筒部４０１の長さは、カートリッジ受け４１１に取り付けられた水質浄化用カートリッジ１５の上流側の端部に達するまでの長さを有し、水質浄化用カートリッジ１５がカートリッジ受け４１１に装着されたときに内筒部４０１の先端と水質浄化用カートリッジ１５の上流側の端部が当接して密閉できるように形成して、カートリッジ装着時には内筒部４０１の外側に原水流路４０２、内筒部４０１の内側にカートリッジ外周流路４０３を形成できるようにする。
この場合に用いられる水質浄化用カートリッジ１５は、第２実施例の場合と同様のものとする。
【０１１８】
そして、頭部１２側では、遮断弁１６，１７の上流に共通の弁内空間４１０を設け、遮断弁１６の下流側には原水吐出側の流路となる弁下流側空間１８を形成するとともに、遮断弁１７の下流側には弁下流側空間１８と隔離された把持部１１側へ接続される流路４０４を形成し、遮断弁１７の下流側の流路４０４とカートリッジ外周流路４０３との間に開口形状が略矩形の開口４０４ａを設け、この開口４０４ａの外方が把持部１１側に形成された内筒部４０１のカートリッジ外周流路４０３の頭部側に位置する端部となり、これにより遮断弁下流側に位置するカートリッジ上流側の流路が形成される。
【０１１９】
カートリッジ受け４１１の内面側に形成された浄水流路４１９ａは、シャワー吐出口形成範囲の外部であって、ストレート吐出口１２ｂを中心として吐出切換弁２６の回転軸設置位置から 180度振った位置（軸対称位置）の把持部１１側に突設した浄水吐出口４１９に至り、水質浄化用カートリッジ１５を通過して浄化された混合水のカートリッジ下流側における専用流路を形成する。
【０１２０】
このため、水質浄化用カートリッジ１５を内筒部４０１に挿通し、先端のキャップ１５ｇをカートリッジ受け４１１に内嵌し、キャップ１５ｐのキャップ端部が内筒部４０１の先端に当接して位置固定すると、内筒部４０１と水質浄化用カートリッジ１５との間に形成される間隙によって、遮断弁１７の下流側に原水流路としてのカートリッジ外周流路４０３が形成されるから、把持部１１のホース接続部１１ｆから原水が流入すると、内筒部４０１の外周側に形成された原水流路４０２を通過して遮断弁１６，１７の上流に設けられた共通の弁内空間４１０に流入し、そして流路切換弁の遮断弁１７を通過した後の原水流路であるカートリッジ外周流路４０３に流入して、原水がカートリッジ外周流路４０３から水質浄化用カートリッジ１５を通過して中央空間部２２に流出するまでの間に浄化され、浄化された混合水がカートリッジ下流側の専用流路である浄水流路４１９ａを通過してシャワー吐出口形成範囲の外部に設けられた浄水吐出口４１９から吐出するようになる。
【０１２１】
このような流路切換弁の下流側に水質浄化用カートリッジを配置した浄水機能付きシャワーヘッドでは、図６３〜６６に示すように、頭部１２に組み込まれた流路切換弁の遮断弁１６，１７の弁座１６ａ，１７ａを配置するとともに流路切換弁前後の流路を仕切るための（第１の）仕切部材４１２と、弁座１６ａを支持するとともに浄水流路４０４と弁下流側空間１８との間を仕切る（第２の）仕切部材４１３と、原水側の遮断弁１６の下流側の流路である弁下流側空間１８と弁下流側空間１８から流入してシャワープレート４１６から吐出するための入口部となるシャワー側空間４１４との間を仕切る（第３の）仕切部材４１５とを配設して、流路切換弁下流側における水質浄化用カートリッジ前後の頭部側流路を形成する。
【０１２２】
このうち、把持部１１の筒部１１ａを一体的に組み合わせた頭部１２では、図６８〜７１に示すように、頭部１２側から突出している筒部１１ａの内側に、所定の流路幅をあけて同心的に筒部１１ａよりも長い内筒部４０１を形成し、その内筒部４０１の内側には、カートリッジ受け４１１を先端部に形成して水質浄化用カートリッジ１５をその頭部側の端部を内嵌して取り付けられるようにするとともに、カートリッジ受け４１１の内面側に浄水流路４１９ａを形成し、この浄水流路４１９ａをシャワー吐出口形成範囲の外部で、把持部１１の筒部１１ａの頭部１２に近接した位置（根元部）にシャワー吐出面側に開口した浄水吐出口４１９に至るまで穿設し、水質浄化用カートリッジ１５を通過して浄化された混合水のカートリッジ下流側における浄水専用流路を形成する。
【０１２３】
そして、頭部１２は、流路切換弁等を収容する空間を有し、頂部が曲面に形成されるとともに主要部が略円筒状に形成された頭部外皮１２ｇに、円筒中心に対して筒部１１ａの反対側の位置に押しボタン１３が貫通する孔１２ｈを穿設し、頭部外皮１２ｇの頂部曲面の裏側には孔１２ｈに接する位置から流路切換弁の弁入口側の隔壁１２ｊまでに至る直線状に形成した複数のリブ１２ｉ，１２ｉを突設し、流路切換弁の弁箱の上部を形成する隔壁１２ｊにより形成された弁内空間４１０には頂部曲面の裏側に弁体支持部材１６ｃ，１７ｃの上面を当接して移動時の案内部材として機能する複数本のリブ１２ｌ，…，１２ｌを突設する。
【０１２４】
（第１の）仕切部材４１２は、図７２，７３に示すように、頭部１２に組み込まれた流路切換弁の１６，１７の両弁座１６ａ，１７ａを取り付けるとともに流路切換弁前後の流路を仕切る板材４１２ａと、この板材４１２ａの上面外周に立設して弁内空間４１０の略下半分の高さを占める隔壁を形成する枠体（弁ケース形成枠）４１２ｂと、板材４１２ａの下面外周には流路４０４を形成する隔壁を下方に立設する枠体（流路枠）４１２ｃとを形成する。
【０１２５】
そして、板材４１２ａの弁座１６ａ，１７ａを形成する位置には弁座１６ａ，１７ａを形成する部材を嵌合する嵌合孔４１２ｄ，４１２ｅを穿設する。各嵌合孔４１２ｄ，４１２ｅは、弁座１６ａと弁座１７ａとが押しボタン１３の押込み量によっていずれか一方の弁が閉じられるように、押し込み方向にずらして穿設する。その嵌合孔穿設位置の下側には弁座抑え６０または（第２の）仕切部材４１３に設けられた弁座抑え４１３ｃ（図７４参照）を嵌合するリング状嵌合部４１２ｆ，４１２ｇを垂下する。
【０１２６】
（第２の）仕切部材４１３は、図７４に示すように、円盤状に形成された板材４１３ａに、一面側には上面側に弁座１６ａまたは１７ａの下面に合わせた形状に形成した弁座抑え４１３ｃを突設し、その弁座抑え４１３ｃの中央部に必要な孔４１３ｂを穿設する。
【０１２７】
（第３の）仕切部材４１５は、図７５に示すように、外周縁に短い円筒状の環状部材４１５ｂ，６４を突設した円盤状の部材に形成し、円盤部４１５ａの中央部に弁下流側空間１８からシャワー側空間４１４あるいはストレート吐出口１２ｂの入口部へ流出するための集合通過部２５を嵌合する嵌合孔６１を穿設する。
また、外周縁の下側の環状部材６４には外周面に雄ねじ６４ａを形成してシャワープレート抑え１２ｆを螺合できるようにする（図６４，６７参照）。
【０１２８】
シャワープレート４１６は、図７６に示すように、円盤状の板材４１６ａの中央部に略円筒状のストレート吐出口１２ｂを形成し、ストレート吐出口１２ｂに隣接した外周寄りの位置に吐出切換弁２６の軸２６ｂを貫通させる軸孔４１６ｂを穿設し、これらが占める領域を除いた板材４１６ａにはシャワー吐出口１２ａとなる小孔を多数個につき穿設する。
【０１２９】
〔作用効果〕
このような構成により、ホース接続部１１ｆから原水が流入すると、内筒部４０１の外周側に形成された原水流路４０２を通過して遮断弁１６，１７の上流に設けられた共通の弁内空間４１０に流入し、押しボタン１３の位置が浅い押込量の位置か深い押込量の位置かに従い遮断弁１６，１７のいずれか一方が開放状態となり、原水吐出か浄水吐出かに分かれる。
【０１３０】
浄水吐出の場合には、押しボタン１３の位置が浅い押込量の位置で、混合水は遮断弁１７の弁座１７ａを通過して下流側の流路４０４から開口４０４ａを介してカートリッジ外周流路４０３に流入し、水質浄化用カートリッジ１５の水質浄化材１５ａを透過して中央空間部２２に流出し、この中央空間部２２からフィルタ１５ｂと殺菌セラミック１５ｄとフィルタ１５ｃとを透過し、さらにカートリッジ受け３１１内の浄水流路４１９ａを介して筒部１１ａの頭部１２に近接した根元部に突設された浄水吐出口４１９から吐出する。
【０１３１】
また、原水の吐出時には、押しボタン１３の位置が深い押込量の位置で、混合水は遮断弁１６の弁座１６ａを通過して弁下流側空間１８に流出し、この弁下流側空間１８から集合通過部２５を介して吐出切換弁２６が選択しているシャワー吐出口１２ａまたはストレート吐出口１２ｂから原水のまま吐出する。
【０１３２】
原水吐出時では、シャワー吐出している場合に、押しボタン１３の操作とは独立に、切換レバー１４を操作して軸部２６ｂを中心に弁体２６ａを回動すると、弁体２６ａがストレート吐出口１２ｂの入口部から外れ、集合通過部２５からでる原水がストレート吐出口１２ｂの入口部へ流入し、ストレート吐出するようになる。
【０１３３】
また、ストレート吐出している場合に、切換レバー１４を反対方向へ操作して、軸部２６ｂを中心に逆回りに弁体２６ａを回動すると、弁体２６ａがストレート吐出口１２ｂの入口部に入り、集合通過部２５からでる原水がストレート吐出口１２ｂの入口部へ流入することを阻止して、シャワー吐出口１２ａ側へ流路を変更し、シャワー側空間４１４に流出し、シャワー吐出口１２ａからシャワー吐出するようになる。
【０１３４】
このような第４実施例では、遮断弁１７を経由してから水質浄化用カートリッジ１５に至る流路を有するシャワーヘッドを形成でき、流路切換弁の各遮断弁１６，１７を水質浄化用カートリッジ１５の上流側に設けることができるようになるため、第３実施例と第４実施例とにより、流路切換弁が水質浄化用カートリッジ１５の上流側と下流側のどちらにでも設けることができるようになる。
【０１３５】
これらは共に、頭部１２に設けられた押しボタン１３の操作によって、各遮断弁１６，１７の開閉が交互に切り換えられ、浄化された混合水か原水かのいずれかであっても容易に選択することができ、さらに原水の場合ではストレート吐出とシャワー吐出とを選択することができる。
なお、流路切換弁への流入路を変更して、遮断弁１６を浄水側とし、遮断弁１７を原水側とすると、浄水側をシャワー吐出とストレート吐出との切換可能な構成に形成できる。
【０１３６】
〔第５実施例〕
〔構成〕
第１，３実施例の浄水機能付きシャワーヘッド１０，３００は流路切換弁と原水用の吐出切換弁とを備えているが、この第５実施例の浄水機能付きシャワーヘッド５００では、図７７〜７９に示すように、流路切換弁のみ備え、吐出には浄水側と原水側とで専用の吐出口を備えるように構成している点が異なる。
以下の説明では、流路の構成に係る部材以外の個々の部材については第１実施例と同じ構成にして、頭部１２に設けた押しボタン１３によって浄水と原水とを切り換えるシャワーヘッドを形成するため、第１〜４実施例における部材と同じ構成の部材については同じ番号または数字の下２桁を合わせるように付して説明を省略する。
【０１３７】
この浄水機能付きシャワーヘッド５００は、図７８，７９に示すように、頭部１２に押しボタン１３を突出し、内部に原水流路と浄水流路とを各別に接続する遮断弁１６と遮断弁１７とを内蔵し、押しボタン１３により遮断弁１６，１７を流路切換弁（水質切換弁）として同時に操作できるようにしている。
【０１３８】
流路切換弁の下流側には、原水側では、図７９，８２に示すように、遮断弁１６の下流側に弁下流側空間１８を設け、その弁下流側空間１８の底面側に複数の貫通孔５１３ｂ，…，５１３ｂを設けてシャワー側空間５１４に流出できるようにし、シャワー側空間５１４の底面側にシャワー吐出口１２ａを設けてシャワー吐出できるようにし、そして、浄水側では、図８１，８３に示すように、遮断弁１７の下流側に弁下流側流路５２０を遮断弁１７の真下からストレート吐出口１２ｂへの入口部を形成する集合通過部２５の真上まで形成し、集合通過部２５の配置位置の下方には浄水流路５１９をストレート吐出口１２ｂに達するまで垂直に垂下する。
【０１３９】
流路切換弁下流側における各々別個に形成される原水側の流路と浄水側の流路とは、図８０〜８３に示すように、把持部１１の筒部１１ａを突出した頭部１２、および頭部１２に組み込まれる各遮断弁の一部を形成する（第１の）仕切部材５１２、浄水流路と原水流路の仕切りを形成する（第２の）仕切部材５１３、浄水吐出口１２ｂへの弁下流側流路５２０の一部を形成する浄水導管５６５、シャワー吐出口１２ａおよびストレート吐出口１２ｂを形成するシャワープレート５１６によって形成される。
【０１４０】
このうち、頭部１２は、図８４〜８５に示すように、把持部側には把持部１１の筒部１１ａを突出し、その突出した筒部１１ａの内側にカートリッジ受け１１ｅを突出し、吐出側には流路切換弁等を収容する頂部が曲面に形成され主要部が円筒状に形成された頭部外皮１２ｇに、円筒中心に対して筒部１１ａの反対側の位置に押しボタン１３が貫通する孔１２ｈを穿設し、頭部外皮１２ｇの頂部曲面の裏側には孔１２ｈに接する位置から流路切換弁の弁入口側の隔壁１２ｊまでに至る直線状に形成した複数のリブ１２ｉ，１２ｉを突設し、流路切換弁の弁箱の上部を形成する隔壁１２ｊの中央部には原水と浄水とを区分する隔壁１２ｋを立設し、隔壁１２ｊと隔壁１２ｋとにより形成された弁内空間５５６，５５７には頂部曲面の裏側に弁体支持部材１６ｃ，１７ｃの上面を当接して移動時の案内部材として機能する複数本のリブ１２ｌ，…，１２ｌを突設する。
【０１４１】
（第１の）仕切部材５１２は、図８６，８７に示すように、頭部１２の吐出側と切換弁組込側との境界を規定する形状を有する仕切り５５を形成し、この仕切り５５の上部に各流路切換弁の入口側流路と接続する原水側弁内空間５５６、浄水側弁内空間５５７を形成し、仕切り５５の下側には弁下流側空間１８を形成する。また、仕切り５５の各弁内空間５５６，５５７を形成する位置には略中央部に弁座１６ａ，１７ａを形成する部材を嵌合する嵌合孔５８，５９を穿設する。
この嵌合孔５８と嵌合孔５９とは、押しボタン１３の押込みによって移動する弁体１６ｂ，１７ｂのいずれか一方が弁座１６ａと弁座１７ａに嵌め込まれて遮断弁１６または１７が閉じられるように、押し込み方向にずらして穿設する。
【０１４２】
弁下流側流路５２０の一部を形成する浄水導管５６５は、図８８に示すように、上端には弁座１７ａの背面側の形状に合わせた上端部５６５ａを形成して、弁体当接面を上方に向けた弁座１７ａを取り付けることができるようにし、下端には仕切部材５１３に形成された円筒状の上端部５６１に内嵌できる径に形成された厚肉円筒状の下端部５６５ｂを形成し、この下端部５６５ｂの外周にはＯリング溝５６５ｃを刻設して、Ｏリング溝５６５ｃにＯリング（図示せず）をはめ込んで仕切部材５１３に設けられた円筒状の導水管の上端部５６１に嵌合した場合にＯリングによって漏止めできるようにしている。
【０１４３】
上端部５６５ａと下端部５６５ｂとの間は、ほぼ水平方向に向けて延設された断面矩形状の流路５６５ｄによって連通し、この流路５６５ｄの流路長さは浄水側の流路切換弁１７の弁座１７ａの中心位置から仕切部材５１３に設けられた円筒状の上端部５６１の中心位置までの直線距離に等しくして、上端部５６５ａを仕切り部材５１２の浄水側の嵌合孔５９にはめ込んだ後、この嵌合孔５９の中心を回動中心として浄水導管５６５を回動させて、仕切部材５１３に設けられた円筒状の上端部５６１の位置まで下端部５６５ｂを移動して位置合わせをすることにより、仕切部材５１３側の所定位置に嵌め合わせることができるようにする。
【０１４４】
（第２の）仕切部材５１３は、図８９に示すように、円盤部５１３ａの外周縁に短い円筒状の環状部材５１３ｃ，５１３ｄを突設した円盤状の部材に形成し、円盤部５１３ａの中央部に浄水導管５６５からストレート吐出口１２ｂへ流出するための集合通過部２５を嵌合する嵌合孔６１を穿設する。さらに、上面側に位置する円筒状の導水管の上端部５６１と下面側に位置する円筒状の導水管５６２とが位置する中央部の外周側に同一円周上に等ピッチで８個の貫通孔５１３ｂを穿設して原水を弁下流側空間１８からシャワー側空間５１４へ流出できるようにする。また、外周縁の下側の環状部材５１３ｄには外周面に雄ねじ５１３ｅを形成して後述のシャワープレート５１６を螺合できるようにするとともに、この環状部材５１３ｄの根元部の外周側にはＯリング溝５１３ｆを刻設する。
【０１４５】
シャワープレート５１６は、図９０に示すように、シャワー吐出口１２ａとストレート吐出口１２ｂとを形成した円盤状の部材で、中央部にストレート吐出口１２ｂとなる孔を穿設し、吐出面におけるストレート吐出口１２ｂによって占められる箇所の残りの面には、シャワー吐出口１２ａとなる小孔を多数個につき穿設し、そして、円盤状の部材の周縁部には上方に湾曲して突出した張出部５１６ａを設け、その内周面側に雌ねじ５１６ｂを形成して、仕切部材５１３に設けた雄ねじ５１３ｅに螺合できるようにし、張出部５１６ａの上端部の内側には拡径した段差部１５６ｄを設けてＯリング溝の代わりとし、（第２の）仕切部材５１３に設けたＯリング（図示せず）を外側から押圧して（第２の）仕切部材５１３との螺合時に漏止めができるようにする（図８１〜８３参照）。
【０１４６】
〔作用効果〕
このように構成した第５実施例においては、頭部１２に組み込まれている押しボタン１３を操作することにより、押しボタン１３が頭部１２より突き出ている状態（浅い押込量）では浄化された混合水が浄水吐出口１２ｂから流出し、押しボタン１３が頭部１２に入り込んで突き出ている量が少なくなっている状態（深い押込量）では、原水がシャワー吐出口１２ａから流出する。
【０１４７】
まず、押しボタン１３が浅い押込量で、原水側の遮断弁１６が閉じ、浄水側の遮断弁１７が開いており、浄化された混合水が流出している時、押しボタン１３を深い押込量になるように押し込むと、遮断弁１６が開き、遮断弁１７が閉じて、原水の吐出に切り換わる。この状態から再度押しボタン１３を押して、押しボタン１３を浅い押込量に変えると、遮断弁１６が閉じ、遮断弁１７が開いて、浄水の吐出に切り換わる。
【０１４８】
浄水の吐出時は、浄化された混合水は遮断弁１７の弁座１７ａを通過して浄水導管５６５により形成される弁下流側流路５２０へ流出し、集合通過部２５を介して導水管５６２が形成する浄水流路５１９に流出し、この浄水流路５１９を通過して浄水吐出口１２ｂから吐出する。
【０１４９】
また、原水の吐出時には、図９１〜９３に示すように、遮断弁１７が閉じ、遮断弁１６が開いて、混合水は遮断弁１６の弁座１６ａを通過して弁下流側空間１８に流出し、この弁下流側空間１８から貫通孔５１３ｂを介してシャワー側空間５１４に流出し、このシャワー側空間５１４よりシャワープレート５１６に形成されたシャワー吐出口１２ａからシャワー吐出する。
【０１５０】
このような第５実施例では、浄水吐出口１２ｂがストレート吐出口を形成し、原水吐出口１２ｂがシャワー吐出口を形成しているため、浄水吐出と原水吐出との区別が容易にでき、また、浄水吐出では吐出切換を行うことなく吐出できて操作性を向上させたことによって、識別性、視認性および操作性が向上する。
【０１５１】
さらに、流路切換弁の原水用の遮断弁１６と浄水用の遮断弁１７とが同じ押しボタン１３によって交互に流路を遮断する交互切換式遮断弁となっており、かつ、原水・浄水吐出での押しボタン１３の押込位置を異ならせているため、頭部１２に突出した押しボタン１３を押すことにより、浄水と原水とが混同することなく利用でき、操作性を一層向上させることができる。
【０１５２】
また、交互切換式遮断弁の原水用の遮断弁１６と浄水用の遮断弁１７とがそれぞれ球状弁体１６ｂ，１７ｂであるため、弁閉時には、球状弁体１６ｂ，１７ｂに加えられる水圧が、コイルスプリング１６ｄ，１７ｄの付勢力とともに、球状弁体１６ｂ，１７ｂを弁座１６ａ，１７ａに押し付けるように作用して、確実にシールすることができる。

第２，４実施例の浄水機能付きシャワーヘッド２００，４００は、流路切換弁と原水用の吐出切換弁とを備えていたが、この第６実施例の浄水機能付きシャワーヘッド６００では、図９４，９５に示すように、流路切換弁のみ備え、流路切換弁の下流側では浄水側と原水側とに専用の流路と吐出口を備えるように構成している点が異なる。
以下の説明では、流路の構成に係る部材以外の個々の部材については第２実施例と同じ構成にして頭部１２に設けた押しボタン１３によって浄水と原水とを切り換えるシャワーヘッドを形成するため、第２〜５実施例における部材と同じ構成の部材については同じ番号または数字の下２桁を合わせるように付して説明を省略する。
【０１５４】
頭部１２側から突出している筒部１１ａの内側に、所定の流路幅をあけて同心的に筒部１１ａよりも長い内筒部６０１を形成し、そして、内筒部６０１の内側には、カートリッジ受け６１１を先端部に形成した突出部を設け、水質浄化用カートリッジ１５を、その頭部側に位置する端部を内嵌することにより取り付けられるようにする。
【０１５５】
内筒部６０１の長さは、カートリッジ受け６１１に取り付けられた水質浄化用カートリッジ１５の上流側の端部に達するまでの長さを有し、水質浄化用カートリッジ１５がカートリッジ受け６１１に装着されたときに内筒部６０１の先端と水質浄化用カートリッジ１５の上流側の端部が当接して密閉できるように形成して、カートリッジ装着時には内筒部６０１の外側に原水流路６０２、内筒部６０１の内側にカートリッジ外周流路６０３を形成できるようにする。
この場合に用いられる水質浄化用カートリッジ１５は、第２実施例の場合と同様のものとする。
【０１５６】
そして、頭部１２側では、遮断弁１６，１７の上流に共通の弁内空間６１０を設け、遮断弁１６の下流側には原水吐出側の流路となる弁下流側空間１８を形成するとともに、遮断弁１７の下流側には弁下流側空間１８と隔離された把持部１１側へ接続される流路６０４を形成し、遮断弁１７の下流側の流路６０４とカートリッジ外周流路６０３との間に開口形状が略矩形の開口６０３ａ，６０４ａを設け、この開口６０３ａ，６０４ａの外方が把持部１１側に形成された内筒部６０１のカートリッジ外周流路６０３の頭部側に位置する端部となり、これにより遮断弁下流に位置するカートリッジ上流側の流路が形成される。
【０１５７】
カートリッジ下流側の流路は、把持部１１側に設けられたカートリッジ受け６１１の内面側に形成された浄水流路６０６から、頭部側に設けられた浄水流路６０８を通過し集合通過部２５を介してストレート吐出口１２ｂに至り、水質浄化用カートリッジ１５により浄化された混合水の専用流路を形成する。
【０１５８】
このため、水質浄化用カートリッジ１５を内筒部６０１に挿通し、先端のキャップ１５ｇをカートリッジ受け６１１に内嵌し、キャップ１５ｐの端部が内筒部６０１の先端に当接して位置固定すると、内筒部６０１と水質浄化用カートリッジ１５との間に形成される間隙によって、遮断弁１７の下流側に原水流路としてのカートリッジ外周流路６０３が形成されるから、把持部１１のホース接続部１１ｆから原水が流入すると、内筒部６０１の外周側に形成された原水流路６０２を通過して遮断弁１６，１７の上流に設けられた共通の弁内空間６１０に流入し、そして流路切換弁の遮断弁１７を通過した後の原水流路であるカートリッジ外周流路６０３に流入して、原水がカートリッジ外周流路６０３から水質浄化用カートリッジ１５を通過して中央空間部２２に流出するまでの間に浄化され、浄化された混合水がカートリッジ下流側の専用流路である浄水流路６０８を通過し、集合通過部２５を介してストレート吐出口１２ｂから吐出するようになる。
【０１５９】
このような流路切換弁の下流側に水質浄化用カートリッジ１５を配置した浄水機能付きシャワーヘッドでは、図９６〜９９に示すように、頭部１２に組み込まれた流路切換弁の遮断弁１６，１７における弁座１６ａ，１７ａを配置するとともに流路切換弁前後の流路を仕切るための（第１の）仕切部材６１２と、弁座１６ａを支持するとともに浄水流路６０４と弁下流側空間１８との間を仕切る（第２の）仕切部材６１３と、原水側の遮断弁１６の下流側の流路である弁下流側空間１８と弁下流側空間１８から流入してシャワープレート５１６から吐出するための入口部となるシャワー側空間６１４との間を仕切る（第３の）仕切部材５１３とを配設して、流路切換弁下流側における水質浄化用カートリッジ前後の頭部側流路を形成する。
【０１６０】
このうち、把持部１１の筒部１１ａを一体的に組み合わせた頭部１２では、図１００，１０１に示すように、頭部１２側から突出している筒部１１ａの内側に、所定の流路幅をあけて同心的に筒部１１ａよりも長い内筒部６０１を形成し、その内筒部６０１の内側にはカートリッジ受け６１１を形成して水質浄化用カートリッジ１５をその頭部側の端部を内嵌して取り付けられるようにするとともに、内筒部６０１の内側から頭部１２の流路切換弁等を収容する内面側に貫通する開口６０３ａを穿設して流路切換弁下流側から水質浄化用カートリッジ上流側への流路を形成し、さらに、カートリッジ受け６１１の内面側には頭部１２の内面側にまで至る浄水流路６０６を形成して水質浄化用カートリッジ下流側における浄水専用流路を形成する。
【０１６１】
そして、頭部１２には、頂部が曲面に形成されるとともに主要部が略円筒状に形成された頭部外皮１２ｇにより流路切換弁１６，１７および各仕切部材６１２，６１３，５１３等を収容する空間を形成し、頭部１２の略円筒状に形成された主要部の中心に対して筒部１１ａの反対側の位置に押しボタン１３が貫通する孔１２ｈを穿設し、頭部外皮１２ｇの頂部曲面の裏側には孔１２ｈに接する位置から流路切換弁の弁入口側の隔壁１２ｊまでに至る直線状に形成した複数のリブ１２ｉ，１２ｉを突設し、流路切換弁の弁箱の上部を形成する隔壁１２ｊにより形成された弁内空間６１０には頂部曲面の裏側に弁体支持部材１６ｃ，１７ｃの上面を当接して移動時の案内部材として機能する複数本のリブ１２ｌ，…，１２ｌを突設する。
【０１６２】
（第１の）仕切部材６１２は、図１０２，１０３に示すように、頭部１２に組み込まれた流路切換弁の１６，１７の両弁座１６ａ，１７ａを取り付けるとともに流路切換弁前後の流路を仕切る板材６１２ａと、この板材６１２ａの上面外周に立設して弁内空間６１０の略下半分の高さを占める隔壁を形成する枠体（弁ケース形成枠）６１２ｂと、板材６１２ａの下面外周には流路６０４を形成する隔壁を下方に立設する枠体（流路枠）６１２ｃとを形成する。
【０１６３】
そして、板材６１２ａの弁座１６ａ，１７ａを形成する位置には弁座１６ａ，１７ａを形成する部材を嵌合する嵌合孔６１２ｄ，６１２ｅを穿設する。各嵌合孔６１２ｄ，６１２ｅは、弁座１６ａと弁座１７ａとが押しボタン１３の押込み量によっていずれか一方の弁が閉じられるように、押し込み方向にずらして穿設する。その嵌合孔穿設位置の下側には弁座抑え６０または（第２の）仕切部材６１３に設けられた弁座抑え６１３ｃ（図１０４参照）を嵌合するリング状嵌合部６１２ｆ，６１２ｇを垂下する。
【０１６４】
（第２の）仕切部材６１３は、図１０４に示すように、円盤状に形成された板材６１３ａに、一面側には上面側に弁座１６ａまたは１７ａの下面に合わせた形状に形成した弁座抑え６１３ｃを突設し、その弁座抑え６１３ｃの中央部に必要な孔６１３ｂを穿設する。そして、他面側には水質浄化カートリッジ下流側の浄水流路６０６と連通する浄水流路６０８を形成する断面が略矩形の筒状に形成された中空角筒部６１３ｄを面に沿って外周縁から中央部まで延設し、中央部に位置する端部には吐出側に設ける嵌合部に見合った径の円筒状端部６１３ｅを垂下し、その円筒状端部６１３ｅの先端部外周にＯリング溝６１３ｆを刻設して（第３の）仕切部材５１３側に形成されている嵌合部を有する接続端と接続可能に形成する。
【０１６５】
〔作用効果〕
このような構成により、ホース接続部１１ｆから原水が流入すると、内筒部６０１の外周側に形成された原水流路６０２を通過して遮断弁１６，１７の上流に設けられた共通の弁内空間６１０に流入し、押しボタン１３の位置が浅い押込量の位置か深い押込量の位置かに従い遮断弁１６，１７のいずれか一方が開放状態となり、原水吐出か浄水吐出かに分かれる。
【０１６６】
浄水吐出の場合には、押しボタン１３の位置が浅い押込量の位置で、混合水は遮断弁１７の弁座１７ａを通過して下流側の流路６０４から開口６０４ａを介してカートリッジ外周流路６０３に流入し、水質浄化用カートリッジ１５の水質浄化材１５ａを透過して中央空間部２２に流出し、この中央空間部２２からフィルタ１５ｂと殺菌セラミック１５ｄとフィルタ１５ｃとを透過し、さらにカートリッジ受け６１１内の浄水流路６０６および（第１の）仕切部材６１２の開口６０７を介して（第２の）仕切部材６１３に形成された浄水流路６０８に流出し、浄水流路６０８から集合通過部２５を介してストレート吐出口１２ｂから吐出する。
【０１６７】
また、原水の吐出時には、図１０５〜１０７に示すように、押しボタン１３の位置が深い押込量の位置で、混合水は遮断弁１６の弁座１６ａを通過して弁下流側空間１８に流出し、この弁下流側空間１８から（第３の）仕切部材５１３に穿設された貫通孔５１３ｂ，…，５１３ｂを介してシャワー側空間６１４に流入し、シャワー吐出口１２ａから原水のまま吐出する。
【０１６８】
このような第６実施例では、遮断弁１７を経由してから水質浄化用カートリッジ１５に至る流路を有するシャワーヘッドを形成でき、流路切換弁の各遮断弁１６，１７を水質浄化用カートリッジ１５の上流側に設けることができるようになるため、第５実施例と第６実施例とにより、流路切換弁が水質浄化用カートリッジ１５の上流側と下流側のどちらにでも設けることができるようになる。
これらは共に、頭部１２に設けられた押しボタン１３の操作によって、各遮断弁１６，１７の開閉が交互に切り換えられ、浄化された混合水か原水かのいずれかであっても容易に選択することができる。
【０１６９】
〔第７実施例〕
〔構成〕
第５実施例の浄水機能付きシャワーヘッド５００は流路切換弁と原水用および浄水用の各専用の吐出口を備えているが、この第７実施例の浄水機能付きシャワーヘッド７００では、図１０８〜１１０に示すように、原水用および浄水用の各吐出口は共用のシャワー吐出口とするように構成している点が異なる。
以下の説明では、流路の構成に係る部材以外の個々の部材については第５実施例と同じ構成にして、頭部１２に設けた押しボタン１３によって浄水と原水とを切り換えるシャワーヘッドを形成するため、第５実施例における部材と同じ構成の部材については同じ番号または数字の下２桁を合わせるように付して説明を省略する。
【０１７０】
この浄水機能付きシャワーヘッド７００は、図１０９，１１１に示すように、頭部１２に押しボタン１３を突出し、この押しボタン１３により同時に操作できるようにした流路切換弁（水質切換弁）としての２つの遮断弁１６，１７を内蔵している。そして、遮断弁１６と遮断弁１７には、原水流路と浄水流路とを各別に接続する。
【０１７１】
流路切換弁の下流側には、図１１２〜１１３に示すように、原水側では、遮断弁１６の下流側に弁下流側空間１８を設け、その弁下流側空間１８の底面側にはシャワー吐出口１２ａを設けてシャワー吐出できるようにし、そして、浄水側でも、遮断弁１７の下流側に弁下流側空間１８が位置して原水の流路と共用するように構成する。
【０１７２】
弁下流側空間１８は、頭部１２に組み込まれる各遮断弁の一部を形成する（第１の）仕切部材１２ｃ、この仕切部材１２ｃとシャワープレート７１６との間に挟持される略円筒状に形成された中間接続部材７１３、シャワー吐出口１２ａを形成するシャワープレート７１６によって形成される。
【０１７３】
中間接続部材７１３は、図１１４に示すように、略円筒状に形成された部材で、その略中央部に外周側に突出した鍔部７１３ａを設け、この鍔部７１３ａにより略円筒状に形成された部材が上下に分けられ、その上側の部材７１３ｂは外周が（第１の）仕切部材１２ｃの下端部に内嵌できるように外形を成形し、下側の部材７１３ｃは外周面にシャワープレート７１６を螺合するための雄ねじ７１３ｅを設け、下側の部材７１３ｃの上端部（鍔部７１３ａの真下）にＯリング溝７１３ｆを刻設する。
【０１７４】
シャワープレート７１６は、図１１５に示すように、円盤状の部材の周縁部には上方に湾曲して突出した張出部７１６ａを設け、その内周面側に雌ねじ７１６ｂを設けて、中間接続部材７１３に設けた雄ねじ７１３ｅに螺合できるようにし、張出部７１６ａの上端部の内側には浅い溝７１６ｄを刻設してＯリング溝とし、中間接続部材７１３に設けたＯリング（図示せず）を外側から押圧して中間接続部材７１３との螺合時に漏止めができるようにする。
【０１７５】
〔作用効果〕
このように構成した第７実施例においては、頭部１２に組み込まれている押しボタン１３を操作することにより、押しボタン１３が浅い押込量では浄化された混合水がシャワー吐出口１２ａから流出し、押しボタン１３が深い押込量では、原水がシャワー吐出口１２ａから流出する。
【０１７６】
そして、押しボタン１３が浅い押込量で、原水側の遮断弁１６が閉じ、浄水側の遮断弁１７が開いており、浄化された混合水が流出している時に、押しボタン１３を深い押込量になるように押し込むと、図１１６〜１１８に示すように、遮断弁１６が開き、遮断弁１７が閉じて、原水の吐出に切り換わる。この状態から再度押しボタン１３を押すと、押しボタン１３が浅い押込量に変わり、図１１１〜１１３に示すように、遮断弁１６が閉じ、遮断弁１７が開いて、浄水の吐出に切り換わる。
【０１７７】
浄水または原水の吐出において、混合水は遮断弁１６または１７の弁座１６ａまたは１７ａを通過して弁下流側空間１８に流出し、この弁下流側空間１８からシャワープレート７１６に形成されたシャワー吐出口１２ａから吐出する。
【０１７８】
このような第７実施例では、浄水と原水のどちらでもシャワー吐出する単純な構成となっており、構成が容易になるとともに操作が容易となり、取扱い易くなる。また、流路切換弁が、交互切換式遮断弁で原水用の遮断弁１６と浄水用の遮断弁１７とがそれぞれ球状弁体１６ｂ，１７ｂであるため、弁閉時には、球状弁体１６ｂ，１７ｂに加えられる水圧が、コイルスプリング１６ｄ，１７ｄの付勢力とともに、球状弁体１６ｂ，１７ｂを弁座１６ａ，１７ａに押し付けるように作用して、確実にシールすることができて、浄水と原水の切換が容易にできる。
【０１７９】
〔第８実施例〕
〔構成〕
第６実施例の浄水機能付きシャワーヘッド６００は、水質浄化用カートリッジの上流側に設けた流路切換弁と原水用および浄水用の各専用の吐出口を備えているが、この第８実施例の浄水機能付きシャワーヘッド８００では、図１１９，１２０に示すように、流路切換弁を水質浄化用カートリッジの上流側に設けるとともに、原水用および浄水用の各吐出口は共用のシャワー吐出口とするように構成している点が異なる。
以下の説明では、流路の構成に係る部材以外の個々の部材については第６実施例と同じ構成にして頭部１２に設けた押しボタン１３によって浄水と原水とを切り換えるシャワーヘッドを形成するため、第６実施例における部材と同じ構成の部材については同じ番号または数字の下２桁を合わせるように付して説明を省略する。
【０１８０】
図１１９〜１２３に示すように、頭部１２側から突出している筒部１１ａの内側に、所定の流路幅をあけて同心的に筒部１１ａよりも長い内筒部８０１を形成し、そして、内筒部８０１の内側には、カートリッジ受け８１１を先端部に形成した突出部を設け、水質浄化用カートリッジ１５を、その頭部側に位置する端部から内筒部８０１に挿入して内嵌することにより取り付けられるようにする。
【０１８１】
内筒部８０１の長さは、カートリッジ受け８１１に取り付けられた水質浄化用カートリッジ１５の上流側の端部に達するまでの長さを有し、水質浄化用カートリッジ１５がカートリッジ受け８１１に装着されたときに内筒部８０１の先端と水質浄化用カートリッジ１５の上流側の端部が当接して密閉できるように形成して、カートリッジ装着時には内筒部８０１の外側に原水流路８０２、内筒部８０１の内側にカートリッジ外周流路８０３を形成できるようにする。
この場合に用いられる水質浄化用カートリッジ１５は、第２実施例の場合と同様のものとする。
【０１８２】
そして、頭部１２側では、遮断弁１６，１７の上流に共通の弁内空間８１０を設け、遮断弁１６の下流側には原水吐出側の流路となる弁下流側空間１８を形成するとともに、遮断弁１７の下流側には弁下流側空間１８と隔離された把持部１１側へ接続される流路８０４を形成し、遮断弁１７の下流側の流路８０４とカートリッジ外周流路８０３との間に開口形状が略矩形の開口８０３ａ，２０４ａを設け、この開口８０３ａ，２０４ａの外方が把持部１１側に形成された内筒部８０１のカートリッジ外周流路８０３の頭部側に位置する端部となり、これにより遮断弁下流に位置するカートリッジ上流側の流路が形成される。
【０１８３】
カートリッジ下流側の流路は、把持部１１側に設けられたカートリッジ受け８１１の内面側に形成された浄水流路８０６から、頭部側に設けられた開口２０７を介して弁下流側空間１８に至り、水質浄化用カートリッジ１５により浄化された混合水がシャワー吐出できるように形成する。
【０１８４】
このため、水質浄化用カートリッジ１５を内筒部８０１に挿通し、先端のキャップ１５ｇをカートリッジ受け８１１に内嵌し、キャップ１５ｐの端部が内筒部８０１の先端に当接して位置固定すると、内筒部８０１と水質浄化用カートリッジ１５との間に形成される間隙によって、遮断弁１７の下流側に原水流路としてのカートリッジ外周流路８０３が形成されるから、把持部１１のホース接続部１１ｆから原水が流入すると、内筒部８０１の外周側に形成された原水流路８０２を通過して遮断弁１６，１７の上流に設けられた共通の弁内空間８１０に流入し、そして流路切換弁の遮断弁１７を通過した後の原水流路であるカートリッジ外周流路８０３に流入して、原水がカートリッジ外周流路８０３から水質浄化用カートリッジ１５を通過して中央空間部２２に流出するまでの間に浄化され、浄化された混合水がカートリッジ下流側の専用流路である浄水流路８０６を通過し、弁下流側空間１８を介してシャワー吐出口１２ａから吐出するようになる。
【０１８５】
このような流路切換弁の下流側に水質浄化用カートリッジ１５を配置した浄水機能付きシャワーヘッド８００では、頭部１２に組み込まれた流路切換弁の遮断弁１６，１７における弁座１６ａ，１７ａを配置するとともに流路切換弁前後の流路を仕切るための（第１の）仕切部材２１２と、弁座１６ａを支持するとともに浄水流路８０４と弁下流側空間１８との間を仕切る（第２の）仕切部材８１３と、シャワープレート７１６を螺合して原水側の遮断弁１６の下流側の流路である弁下流側空間１８を形成する中間接続部材７１３とを配設して、流路切換弁下流側における水質浄化用カートリッジ前後の頭部側流路を形成する。
【０１８６】
このうち、把持部１１の筒部１１ａを一体的に組み合わせた頭部１２では、図１２１〜１２３に示すように、頭部１２側から突出している筒部１１ａの内側に、所定の流路幅をあけて同心的に筒部１１ａよりも長い内筒部８０１を形成し、その内筒部８０１の内側にはカートリッジ受け８１１を形成して水質浄化用カートリッジ１５をその頭部側の端部を内嵌して取り付けられるようにするとともに、内筒部８０１の内側から頭部１２の流路切換弁等を収容する内面側に貫通する開口８０３ａを穿設して流路切換弁下流側から水質浄化用カートリッジ上流側への流路を形成し、さらに、カートリッジ受け８１１の内面側には頭部１２の内面側にまで貫通する浄水流路８０６を形成して水質浄化用カートリッジ下流側における浄水専用流路を形成する。
【０１８７】
（第１の）仕切部材２１２は、実施例２と同様に形成して、流路切換弁前後に流路を形成できるようにするとともに、流路切換弁下流側に設ける水質浄化用カートリッジ前後の流路への開口を設けて混合水を流通可能に形成する。
（第２の）仕切部材８１３は、図１２４に示すように、外周端に下方に向けて垂下したリング状端部を有する円盤状に形成された板材８１３ａに、上面側には必要な孔８１３ｂを穿設して原水側の弁座１６ａの下面に合わせた形状に上端部を形成した弁座抑え８１３ｃを突設し、その弁座抑え８１３ｃを原水側の弁座１６ａの下面に嵌め合わせた場合に高さが浄水流路８０４の高さになるように形成し、そして、下面側は特別な突出物を設けず平面に形成する。さらに、リング状端部には浄水の通過を妨げることがないように、開口２０７に対応する位置に切欠部８１３ｄを設ける。
【０１８８】
〔作用効果〕
このような構成により、ホース接続部１１ｆから原水が流入すると、内筒部８０１の外周側に形成された原水流路８０２を通過して遮断弁１６，１７の上流に設けられた共通の弁内空間８１０に流入し、押しボタン１３の位置が浅い押込量の位置か深い押込量の位置かに従い遮断弁１６，１７のいずれか一方が開放状態となり、原水吐出か浄水吐出かに分かれる。
【０１８９】
浄水吐出の場合には、図１１９〜１２３に示すように、押しボタン１３の位置が浅い押込量の位置で、混合水は遮断弁１７の弁座１７ａを通過して下流側の流路８０４から開口２０４ａおよび開口８０３ａを介してカートリッジ外周流路８０３に流入し、水質浄化用カートリッジ１５の水質浄化材１５ａを透過して中央空間部２２に流出し、この中央空間部２２からフィルタ１５ｂと殺菌セラミック１５ｄとフィルタ１５ｃとを透過し、さらにカートリッジ受け８１１内の浄水流路８０６から開口２０７を通過して頭部１２に形成された弁下流側空間１８に流出し、シャワー吐出口１２ａを介してシャワー吐出する。
【０１９０】
また、原水の吐出時には、図１２５〜１２７に示すように、押しボタン１３の位置が深い押込量の位置で、混合水は遮断弁１６の弁座１６ａを通過して弁下流側空間１８に流出し、この弁下流側空間１８からシャワー吐出口１２ａを介して原水のままシャワー吐出する。
【０１９１】
このような第８実施例では、遮断弁１７を経由してから水質浄化用カートリッジ１５に至る流路を有するシャワーヘッドを形成でき、流路切換弁の各遮断弁１６，１７を水質浄化用カートリッジ１５の上流側に設けることができるため、第７実施例と第８実施例とにより、遮断弁１６，１７が水質浄化用カートリッジ１５の上流側と下流側のどちらにでも設けることができるようになる。
これらは共に、頭部１２に設けられた押しボタン１３の操作によって、各遮断弁１６，１７の開閉が交互に切り換えられ、浄化された混合水か原水かのいずれかであっても容易に選択することができる。
【０１９２】
〔第９実施例〕
〔構成〕
第１〜４実施例では流路切換弁の下流側に頭部の外側から操作可能な吐出切換弁を設け、第５〜８実施例では流路切換弁の下流側には吐出切換弁を設けずに原水と浄水の専用の吐出側流路を形成しているが、この第９実施例の浄水機能付きシャワーヘッド９００では、図１２８〜１２９に示すように、流路切換弁は同様に形成されているが、吐出切換弁については回動式操作部を有し、外観上は吐出切換弁が設けられていないかのように突出している部分がない形状に形成して、頭部のシャワー吐出面側の端部を回動することによって吐出状態を切り換えるようにした吐出切換弁９０１を組み込んだ構成にしている点が異なる。
以下の説明では、吐出側の流路の構成に係る部材以外の個々の部材については第１実施例と同じ構成にして頭部１２に設けた押しボタン１３によって浄水と原水とを切り換えるシャワーヘッドを形成するため、第１〜４実施例における部材と同じ構成の部材については同じ番号または数字の下２桁を合わせるように付して説明を省略する。
【０１９３】
頭部１２には、図１３０〜１３４に示すように、上部に押しボタン１３によって動作する流路切換弁の原水側の遮断弁１６と浄水側の遮断弁１７とが配置され、その下部に回動式操作部を有する吐出切換弁９０１が組み込まれ、この吐出切換弁９０１は頭部１２に固着される固定仕切部材９４０と、この固定仕切部材９４０に回動自在に組付けた回動部材９６０とからなり、ストレート吐出とシャワー吐出の他に、強弱吐出、脈動吐出または間欠吐出あるいはマッサージ吐出等を行わせる第３の吐出口を設ける。以下では、第３の吐出口としてマッサージ吐出の場合を説明する。
【０１９４】
頭部１２に組み込まれた流路切換弁の各遮断弁１６，１７の下流側には、流路切換弁を形成する仕切部材９１２との間に任意の空隙を開けて固定仕切部材９４０を配置することにより、原水および浄水のどちらも流入する弁下流側空間１８を形成し、各遮断弁１６，１７から流出する原水および浄水のどちらも、同一の弁下流側空間１８に流入するように形成する。
【０１９５】
吐出切換弁９０１を形成する固定仕切部材９４０は、頭部１２に内蔵し固着して弁下流側空間１８と各吐出口への流路との間を仕切るとともに弁下流側空間１８から特定の吐出口への流路に混合水を流出させる流出口９４１を設け、この固定仕切部材９４０に回動自在に組み付けられる回動部材９６０は、固定仕切部材９４０の流出口９４１から流出する混合水を、シャワー吐出口１２ａ，ストレート吐出口１２ｂ，マッサージ吐出口１２ｎのいずれかに導く流路を内部に形成する。

〔作用効果〕
このような回動式操作部を有する吐出切換弁９０１では、各吐出口１２ａ，１２ｂ，１２ｎを形成するとともに混合水を各吐出口１２ａ，１２ｂ，１２ｎに導入する各案内流路９６２ａ，９６２ｂ，９６２ｃおよび吐出流路９１０，９２０，９３０を回動位置によって選択できるように形成したことによって、ストレート吐出を選択した場合には、図１５０に示すように、固定仕切部材９４０に設けられた流出口９４１が、突出部９４２を中心にして位置止め部材収容部９４３と横方向の直線上に設けられているとき、軸着部材９６２でもストレート吐出口１２ｂへ連通する開口９６２ｌが孔９６２ｇを中心にしてマッサージ吐出口へ連通する開口９６２ｎと凹部９６２ｑとが横方向の直線上に位置し、この配置関係で固定仕切部材９４０の真下に軸着部材９６２が位置するため、位置止め部材９４０ｆが凹部９６２ｑに入って位置を確定すると、混合水が流出口９４１から開口９６２ｌを介してストレート吐出用案内流路９６２ａに流出し、ストレート吐出流路９１０を介してストレート吐出口１２ｂより吐出する。
【０２１５】
次に、外周部材９６６の外周面を手で持ち、回動して、マッサージ吐出を選択した場合には、図１５１に示すように、固定仕切部材９４０に設けられた流出口９４１と、突出部９４２と、位置止め部材収容部９４３とが横方向の直線上に設けられているとき、軸着部材９６２ではマッサージ吐出口１２ｎへ連通する開口９６２ｎが孔９６２ｇを中心にしてストレート吐出口１２ｂへ連通する開口９６２ｌと凹部９６２ｏとが横方向の直線上に位置し、この配置関係で固定仕切部材９４０の真下に軸着部材９６２が位置するため、位置止め部材９４０ｆが凹部９６２ｏに入って位置を確定すると、混合水は流出口９４１から開口９６２ｎを介してマッサージ吐出用案内流路９６２ｂに流出し、マッサージ吐出流路９２０を介してマッサージ吐出口１２ｎより吐出する。このとき、マッサージ吐出流路９２０への流入口となっている傾斜流出口９６４ｂから流出する混合水の動水圧により、マッサージ吐出流路９２０に収容したボール９６９を流路に沿って移動させ、ボール９６９が通過するときに塞ぐマッサージ吐出口１２ｎからの流出が途切れることにより、間欠的に混合水が吐出されてマッサージ効果を発揮する。
【０２１６】
また、外周部材９６６の外周面を手で持ち、回動して、シャワー吐出を選択した場合には、図１５２に示すように、固定仕切部材９４０に設けられた流出口９４１と、突出部９４２と、位置止め部材収容部９４３とが横方向の直線上に設けられているとき、軸着部材９６２ではシャワー吐出口１２ａへ連通する開口９６２ｍが孔９６２ｇを中心にして凹部９６２ｐと横方向の直線上に位置し、この配置関係で軸着部材９６２が固定仕切部材９４０の真下に位置するため、位置止め部材９４０ｆが凹部９６２ｐに入って位置を確定すると、混合水が流出口９４１から開口９６２ｍを介してシャワー吐出用案内流路９６２ｃに流出し、さらにシャワー吐出流路９３０を介してシャワー吐出口１２ａより吐出する。
【０２１７】
このようにして、手動により外周部材９６６を一体に形成した回動部材９６０を回動操作することにより、ストレート吐出、マッサージ吐出、シャワー吐出を容易に切り換え、３種の吐出形態を任意に使用することができるようになる。

〔第１０実施例〕
〔構成〕
第９実施例では水質浄化用カートリッジの下流側に流路切換弁と回動式操作部を有する吐出切換弁とを組み込んでいるが、この第１０実施例の浄水機能付きシャワーヘッド１０００では、図１５３〜１５５に示すように、流路切換弁と回動操作部を有する吐出切換弁１１００との間に水質浄化用カートリッジを組み込んだ構成にしている点が異なる。
以下の説明では、流路切換弁から吐出切換弁までの混合水の流路の構成に係る部材以外の個々の部材については第９実施例と同じ構成にして頭部１２に設けた押しボタン１３によって浄水と原水とを切り換えるシャワーヘッドを形成するため、第９実施例における部材と同じ構成の部材については同じ番号または数字の下２桁を合わせるように付して説明を省略する。

図１５３〜１５８に示すように、頭部１２には、上部に押しボタン１３によって動作する流路切換弁の原水側の遮断弁１６と浄水側の遮断弁１７とが配置され、その下流側及び側部に水質浄化用カートリッジ１５側への迂回路を形成し、その下流側に、頭部１２に固着される固定仕切部材１０４０と、この固定仕切部材１０４０に回動自在に組付けた回動部材１０６０とからなる回動式操作部とを有する吐出切換弁１１００が組み込まれる。
【０２２０】
頭部１２側から把持部１１側に突出している筒部１１ａの内側に、所定の流路幅をあけて同心的に筒部１１ａよりも長い内筒部１００１を形成し、そして、内筒部１００１の内側には、カートリッジ受け１０１１を先端部に形成した突出部を設け、水質浄化用カートリッジ１５を、その頭部側に位置する端部から内筒部１００１に挿入して内嵌することにより取り付けられるようにする。
【０２２１】
内筒部１００１の長さは、カートリッジ受け１０１１に取り付けられた水質浄化用カートリッジ１５の上流側の端部に達するまでの長さを有し、水質浄化用カートリッジ１５がカートリッジ受け１０１１に装着されたときに内筒部１００１の先端と水質浄化用カートリッジ１５の上流側の端部が当接して密閉できるように形成して、カートリッジ装着時には内筒部１００１の外側に原水流路１００２、内筒部１００１の内側にカートリッジ外周流路１００３を形成できるようにする。
この場合に用いられる水質浄化用カートリッジ１５は、第２実施例の場合と同様のものとする。
【０２２２】
そして、頭部１２の遮断弁１６，１７の上流側に共通の弁内空間１０７０を設け、遮断弁１６の下流側には原水吐出側の流路となる弁下流側空間１８を形成するとともに、遮断弁１７の下流側には弁下流側空間１８と隔離されるとともに把持部１１側へ接続される流路１００４を形成し、この流路１００４に隣接して（第１の）仕切部材１０１２の弁箱１０１２ａにより仕切られた弁内空間１０７０の外側に弁箱外流路１０１２ｉを設け、遮断弁１７の下流側のカートリッジ外周流路１００３との連通用に開口形状が略矩形の開口１０１２ｆを設け、この開口１０１２ｆの外方が把持部１１側に形成された内筒部１００１のカートリッジ外周流路１００３の頭部側に位置する端部となり、これにより遮断弁下流に位置する頭部１２内におけるカートリッジ上流側の流路が形成される。
【０２２３】
カートリッジ下流側の流路は、把持部１１側に設けられたカートリッジ受け１０１１の内面側に形成された浄水流路１００６から、頭部１２側に設けられた開口１０１２ｇを介して弁下流側空間１８に至り、水質浄化用カートリッジ１５を通過して浄化された混合水が頭部１２に組み込まれた吐出切換弁１１００に流入できるように形成される。
【０２２４】
このため、水質浄化用カートリッジ１５を内筒部１００１に挿通し、先端のキャップ１５ｇをカートリッジ受け１０１１に内嵌し、キャップ１５ｐの端部が内筒部１００１の先端に当接して位置固定すると、内筒部１００１と水質浄化用カートリッジ１５との間に形成される間隙によって、遮断弁１７の下流側に原水流路としてのカートリッジ外周流路１００３が形成されるから、把持部１１のホース接続部１１ｆから原水が流入すると、内筒部１００１の外周側に形成された原水流路１００２を通過して遮断弁１６，１７の上流に設けられた共通の弁内空間１０７０に流入し、そして流路切換弁の遮断弁１７を通過した後の原水流路であるカートリッジ外周流路１００３に流入して、原水がカートリッジ外周流路１００３から水質浄化用カートリッジ１５を通過して中央空間部２２に流出するまでの間に浄化され、浄化された混合水がカートリッジ下流側の専用流路である浄水流路１００６を通過し、弁下流側空間１８に流入する。この後の流路は、吐出切換弁１１００の下端部に形成された外周部材１０６６を操作することにより選択されるストレート吐出（図１５６参照）、マッサージ吐出（図１５７参照）、シャワー吐出（図１５８参照）のいずれかに従って定められた流路を経由して吐出する。
【０２２５】
このような流路切換弁の下流側に水質浄化用カートリッジ１５を配置した浄水機能付きシャワーヘッド１０００では、頭部１２に組み込まれた流路切換弁の遮断弁１６，１７における弁座１６ａ，１７ａを配置するとともに流路切換弁前後の流路を仕切るための（第１の）仕切部材１０１２と、弁座１６ａを支持するとともに流路１００４と弁下流側空間１８との間を仕切る（第２の）仕切部材１０１３と、吐出切換弁１１００の回動部材１０６０を取り付けて遮断弁１６の下流側の流路である弁下流側空間１８を形成する固定仕切部材１０４０とを配設して、流路切換弁下流側における水質浄化用カートリッジ前後の頭部側流路を形成する。
【０２２６】
このうち、把持部１１の筒部１１ａを一体的に組み合わせた頭部１２では、図１５９〜１６０に示すように、把持部側には把持部１１の筒部１１ａを突出し、その突出した筒部１１ａの内側にカートリッジ受け１０１１を突出し、吐出側には流路切換弁等を収容する頂部が曲面に形成され主要部が円筒状に形成された頭部外皮１２ｇに、その外皮の円筒中心に対して筒部１１ａの反対側の位置に押しボタン１３が貫通する孔１２ｈを穿設し、流路切換弁の弁箱の上部を形成する隔壁１２ｊの把持部側には原水を弁内空間１０７０の上部に導入する流路１０７０ａを形成する隔壁１２ｍを設け、この隔壁１２ｍによって隔壁１２ｊから原水側の流路１００２の開口位置まで仕切ることにより頭部外皮１２ｇの原水流路開口位置から弁内空間１０７０までの流路１０７０ａが形成され、また隔壁１２ｊにより形成された弁内空間１０７０には頂部曲面の裏側に弁体支持部材１６ｃ，１７ｃの上面を当接して移動時の案内部材として機能する複数本のリブ１２ｌ，…，１２ｌを突設する。
【０２２７】
そして、頭部１２側から突出している筒部１１ａの内側に、所定の流路幅をあけて同心的に筒部１１ａよりも長い内筒部１００１を形成し、その内筒部１００１の内側にはカートリッジ受け１０１１を形成して水質浄化用カートリッジ１５をその頭部側の端部を内嵌して取り付けられるようにするとともに、内筒部１００１の内側から頭部１２の流路切換弁等を収容する側に貫通する開口１００３ａを穿設して流路切換弁下流側から水質浄化用カートリッジ上流側への流路を形成し、さらに、カートリッジ受け１０１１の内面側には頭部１２の流路切換弁等を収容する側にまで貫通する浄水流路１００６を形成して水質浄化用カートリッジ下流側における浄水専用流路を形成する。
【０２２８】
（第１の）仕切部材１０１２は、図１６１〜１６２に示すように、頭部１２の吐出側と流路切換弁組込側との境界を規定する形状を有する仕切り１０５５を形成し、この仕切り１０５５の上面側に弁箱形成隔壁１０１２ａを立設して流路切換弁の入口側流路と接続する弁内空間１０７０を形成し、弁内空間１０７０内に位置する仕切り１０５５は弁外にあたる位置の仕切り１０５５よりも高く形成して浄水側の遮断弁１７の下流側における混合水の流れる空間としての流路１００４を形成し、弁外にあたる位置の仕切り１０５５の下側には端縁に頭部嵌合用円筒部としての端縁隔壁１０１２ｂを垂下して弁下流側空間１８を形成する。
【０２２９】
また、仕切り１０５５の弁内空間１０７０を形成する位置には、押しボタン１３の押込み中心線から略等しい間隔に離した位置であって押し込み方向にずらした位置に各弁座１６ａ，１７ａを形成する部材を嵌合する嵌合孔５８，５９を穿設する。この嵌合孔５８と嵌合孔５９との押し込み方向への位置ずれは、押しボタン１３の押込みによって、弁座１６ａと弁座１７ａとのいずれか一方の弁が閉じるために必要な位置ずれ量を与えるものとする。
【０２３０】
さらに、弁内空間１０７０の内側に位置する仕切り１０５５の下面側に設けた流路１００４から、開口１００３ａを介してカートリッジ外周流路１００３へ連通する流路１０１２ｉを形成する隔壁１０１２ｄを、弁外にあたる位置の仕切り１０５５が上面側に盛り上げられた形状に形成して、浄水側の遮断弁１７から流出する混合水を把持部１１側へ誘導する流路１０１２ｉとなるように設ける。そして、端縁隔壁１０１２ｂを開通し、流路１０１２ｉと把持部側のカートリッジ上流側の流路１００３との間を連通させる開口１０１２ｆを開設する。

【０２３２】
〔作用効果〕
このような構成により、ホース接続部１１ｆから原水が流入すると、内筒部１００１の外周側に形成された原水流路１００２を通過して遮断弁１６，１７の上流に設けられた共通の弁内空間１０７０に流入し、押しボタン１３の位置が浅い押込量の位置か深い押込量の位置かに従い遮断弁１６，１７のいずれか一方が開放状態となり、原水吐出か浄水吐出かに分かれる。

浄水吐出の場合には、図１５３〜１５５に示すように、押しボタン１３の位置が浅い押込量の位置で、混合水は遮断弁１７の弁座１７ａを通過して下流側の流路１００４から流路１０１２ｉ、開口１０１２ｆおよび開口１００３ａを介してカートリッジ外周流路１００３に流入し、水質浄化用カートリッジ１５の水質浄化材１５ａを透過して中央空間部２２に流出し、この中央空間部２２からフィルタ１５ｂと殺菌セラミック１５ｄとフィルタ１５ｃとを透過し、さらにカートリッジ受け１０１１内の浄水流路１００６から開口１０１２ｇを通過して頭部１２に形成された弁下流側空間１８に流出し、回動操作部を有する吐出切換弁１１００の設定に従って吐出する。
【０２３４】
また、原水の吐出時には、押しボタン１３の位置が深い押込量の位置で、混合水は遮断弁１６の弁座１６ａを通過して弁下流側空間１８に流出し、この弁下流側空間１８から回動操作部を有する吐出切換弁１１００の設定に従って吐出する。
【０２３５】
このような第１０実施例では、遮断弁１７を経由してから水質浄化用カートリッジ１５に至る流路を有するシャワーヘッドを形成でき、流路切換弁の各遮断弁１６，１７を水質浄化用カートリッジ１５の上流側に設けることができるようになるため、回動操作部を有する吐出切換弁１１００を組み込んだ場合であっても、第９実施例と第１０実施例とにより、流路切換弁が水質浄化用カートリッジ１５の上流側と下流側のどちらにでも設けることができるようになる。
これらは共に、頭部１２に設けられた押しボタン１３の操作によって、各遮断弁１６，１７の開閉が交互に切り換えられ、浄化された混合水か原水かのいずれかであっても容易に選択することができる。

【発明の効果】
以上のように本発明の請求項１に係る浄水機能付きシャワーヘッドでは、上記水質浄化用カートリッジは、筒状に形成されて上記把持部内を外周側流路と中央空間部とに区画する水質浄化材を有することにより、上記外周側流路を通過して上記吐出切換弁へ連通可能な原水流路と、上記外周側流路から水質浄化材を透過して上記中央空間部へ流れ込み上記吐出切換弁へ連通可能な浄水流路とを形成し、原水吐出時には、上記原水が、浄水吐出時に上記水質浄化材の外周側表面に蓄積された目詰まりを引き起こす固形物質その他の蓄積物を洗い流すため、浄水吐出時に目詰まりしにくくし、水質浄化材の浄化能力を高レベルに維持するとともに寿命を長くする。
【０２４１】
また、請求項２に係る浄水機能付きシャワーヘッドでは、前記吐出切換弁を、略一定角度異なる位置でストレート吐出口、シャワー吐出口または第３の吐出口への各吐出路に接続する開口を設けた回動式の切換弁に形成したことにより、回動角を略一定量移動することによってストレート吐出口、シャワー吐出口または第３の吐出口の３吐出形態に容易に切り換えることができ、取扱いが簡素化でき、しかも使用性を大幅に向上することができる。

[0018]
As shown in FIGS. 5 to 7, the shower head 10 with a water purification function houses a water purification cartridge 15 inside the grip portion 11.
In the gripping part 11 that accommodates the water purification cartridge 15, the outer peripheral flow path 21 of the water purification cartridge 15 is a part of the raw water flow path, and the central space 22 of the water purification cartridge 15 is a part of the water purification flow path. Use as part.
[0019]
The water purification cartridge 15 includes a water purification material 15a formed in a cylindrical shape by providing a hole (central space portion 22) concentrically with the central axis, and filters 15b, 15c made of nonwoven fabric, sponge, nets, or the like on the downstream side. The sterilized ceramic 15d in the form of particles or pellets sandwiched between the two is accommodated in two spaces formed by caps 15e, 15f, 15g divided into three parts.
[0020]
And it has a cap 15e formed in a cylindrical shape with a bottom having a large number of slits on the peripheral wall, and a water purification material support wall having a surface perpendicular to the axial direction in which a hole serving as a fluid passage is formed in the center of the cylindrical shape. The water purification material 15a is accommodated in a space provided by a cap 15f having a fitting portion with the other cap 15e, 15g at each end.

Further, two cylinders having different diameters from the cap 15f are connected by a wall surface perpendicular to the axial direction, and a fitting portion with the cap 15f is formed on the larger diameter cylinder of the two cylinders, and the smaller diameter cylinder is formed. Sterilization ceramic 15d sandwiched between filters 15b and 15c in the inner space of a large-diameter cylinder provided by a cap 15g formed with a fitting portion with a cartridge receiver 11e (described later) provided on the head 12 side. To accommodate.
[0022]
The water purification material 15a to be contained is made of activated carbon as a main component and hardened in a cylindrical shape. When mixed water permeates between the cylindrical outer peripheral surface and the center hole, chemical components dissolved in water and Floating fine solid substances are adsorbed or filtered.
[0023]
In addition, the sterilizing ceramic 15d is obtained by adsorbing silver or copper to a surface obtained by mixing zinc oxide, montmorillonite or the like with calcium phosphate as a base material and sintering it in a granular or pellet form.

[0056]
[Function and effect]
In the embodiment configured as described above, by operating the push button 13 incorporated in the head 12, the purified mixture is obtained when the push button 13 protrudes from the head 12 (shallow push amount). The raw water flows out in a state where the amount of water that has flowed out and the push button 13 has entered and protruded from the head 12 is small (a deep pushing amount).
[0057]
First, when the mixed water purified with a shallow pushing amount is flowing out as shown in FIGS. 8 to 10 and 12, the push button 13 is set so as to have a deep pushing amount as shown in FIGS. 26 to 28. When the button is pressed, the second switching top 13d that is in contact with the push button 13 presses the first switching top 13c and transmits a pressing force from the first switching top 13c to the switching shaft 13a to resist the urging force of the coil spring 53. Then, the switching shaft 13a is moved in the direction approaching the side wall of the partition member 12c.
[0058]
At this time, when the first switching top 13c slides in the groove of the switching ring 13b and moves until it disengages from the groove, the first switching top 13c pushed by the second switching top 13d becomes the second switching top 13d. According to the shape of the contact portion with the first switching top 13c, it moves so as to change the direction of close contact and rotates as a result, changing the relative position between the first switching top 13c and the end face 36b of the switching ring 13b, The shut-off valve 16 is opened and the shut-off valve 17 is closed to switch to the outflow of raw water.
[0059]
The shut-off valve 16 is opened, the shut-off valve 17 is closed, the switching shaft 13a is returned by the amount of play by the biasing force of the coil spring 53, and the end of the rib provided on the first switching top 13c is engraved on the switching ring 13b. When the position is fixed by coming into contact with the shallow groove side, the mixed water flowing out becomes raw water.
[0060]
The push button 13 is pushed again, and the pressing force is transmitted from the second switching top 13d in contact with the push button 13 to the first switching top 13c and further to the switching shaft 13a, thereby resisting the biasing force of the coil spring 53. When the switching shaft 13a is moved in the direction close to the side wall of the partition member 12c, the end of the rib provided on the first switching top 13c is engaged with the shallow groove 36a (361) formed in the switching ring 13b. And the first switching top 13c pushed by the second switching top 13d moves so as to change the direction of contact according to the shape of the contact portion between the second switching top 13d and the first switching top 13c. And the relative position between the first switching top 13c and the end face 36b of the switching ring 13b is changed.
[0061]
As a result, as shown in FIGS. 8 to 10, the rib 43 provided in the first switching top 13 c enters the deep groove 36 a (362) in the axial direction of the switching ring 13 b, and the first biasing force of the coil spring 53 causes the first The rib 43 provided on the switching top 13c is slid along the groove of the switching ring 13b in a direction away from the side wall of the partition member 12c, and the switching shaft 13a in contact with the first switching top 13c is partitioned. It moves to the direction away from the side wall of the member 12c, the shutoff valve 16 is closed, the shutoff valve 17 is opened, and it switches to the outflow of purified water.
[0062]
When the purified water flows out, as shown in FIG. 12, it passes through the valve seat 17a of the shutoff valve 17 and flows out to the valve downstream side flow path 20, and the purified water flow path from the valve downstream side flow path 20 through the purified water conduit 65. The water is discharged from the purified water discharge port 19 formed at the lower end of 62.
When the raw water flows out, as shown in FIGS. 26 to 28, it passes through the valve seat 16 a of the shutoff valve 16 and flows out into the valve downstream space 18, and is switched from the valve downstream space 18 via the collective passage 25. Shower discharge or straight discharge specified by the lever 14 is performed.
[0063]
When discharging raw water, when the shower is discharged, the valve body 26a is straightened by operating the switching lever 14 and rotating the valve body 26a about the shaft portion 26b independently of the operation of the push button 13. The mixed water coming out of the inlet portion of the discharge port 12b and coming out of the collecting passage portion 25 flows into the inlet portion of the straight discharge port 12b and is discharged straight.
[0064]
Further, when the raw water is discharged straight, when the switching lever 14 is operated in the opposite direction and the valve body 26a is rotated in the reverse direction about the shaft portion 26b, the valve body 26a becomes the straight discharge port 12b. The mixed water generated from the collecting passage 25 is prevented from flowing into the inlet of the straight discharge port 12b, the flow path is changed to the shower discharge port 12a, and flows into the shower side space 18a. The shower is discharged from the shower discharge port 12a.
[0065]
In such a 1st Example, since the purified water discharge port 19 is formed in the shower discharge port formation area separately from the raw water discharge flow path, it can be easily distinguished from the raw water discharge and at the time of purified water discharge, It can be used without switching between straight discharge and the operation becomes easy, and the discrimination and operability can be improved.
[0066]
Further, the size restriction on the flow path switching valve composed of the shut-off valves 16 and 17 for switching the water quality can be expanded to a range that can be incorporated into the head 12, and the size restriction of the flow path switching valve. Since the flow path switching valve can be operated on the head 12 side, the operability is improved, and the weight distribution between the head 12 and the grip portion 11 can be distributed in a well-balanced manner. The shape and structure can be well balanced in handling.
[0067]
By incorporating the water purification cartridge 15 in the grip 11, a part of the raw water flow path can be formed on the outer peripheral side of the water purification cartridge 15, and the water quality purification provided in the water purification cartridge 15 from this raw water flow path. A part of the purified water flow path that reaches the central space 22 formed in the center via the material 15a can be formed, the flow path configuration can be simplified and compact, and the structure of the gripping part 11 is simplified. More contents of the water purification material 15a can be stored.
[0068]
The flow path upstream of the water purification material 15a is a shared flow path for raw water and purified water, and solid substances and other accumulated substances that cause clogging accumulated during the purification water discharge can be washed away during the raw water discharge. It is possible to make clogging difficult and extend the life of the water purification material 15a.
[0069]
A water purification cartridge 15 is incorporated in the gripping part 11, and a flow path switching valve is incorporated in the head part 12. The flow path can be simplified, the weight distribution is good, and the shower head has a very good balance in handling. It becomes light and cheap.
[0070]
The flow path switching valve protrudes from the head 12 because the shut-off valve 16 for raw water and the shut-off valve 17 for water purification are alternately switching shut-off valves that alternately shut off the flow path by the same push button 13. By pushing the push button 13, it is possible to switch between clean water and raw water and improve operability.
[0071]
Moreover, since the shut-off valve 16 for raw water and the shut-off valve 17 for purified water are spherical valve bodies 16b and 17b, respectively, the water pressure applied to the spherical valve bodies 16b and 17b when the valves are closed is as follows: Together with the urging force of the coil springs 16d and 17d, the spherical valve bodies 16b and 17b act so as to be pressed against the valve seats 16a and 17a, so that the sealing can be ensured.
[0072]
Since the discharge switching valve 26 is a lever-operated cutoff valve formed in the flow path provided downstream of the raw water side cutoff valve 16 among the flow path switching valves, Either straight discharge can be easily selected, and high convenience can be maintained.
If the inflow path to the flow path switching valve is changed so that the shutoff valve 16 side is the purified water side and the shutoff valve 17 is the raw water side, a flow path that can be switched between shower discharge and straight discharge is provided on the purified water side. Can be configured.
In this embodiment, the flow path switching valve is provided with the two shutoff valves 16 and 17, but the flow path may be switched with one shutoff valve.
This shower head 10 with a water purifying function can be used not only in a kitchen but also in a washroom, a bathroom, etc., and has very high versatility.

[0105]
[Function and effect]
In the third embodiment configured as described above, the push button 13 incorporated in the head 12 is operated, and the push button 13 is purified in a state where it protrudes from the head 12 (shallow push amount). In a state where the mixed water flows out from the purified water discharge port 319 and the push button 13 enters the head 12 and the amount of protrusion is small (deep push amount), the switch lever 14 is operated to turn the discharge switch valve 26 on. By selecting the shower discharge or the straight discharge, the raw water flows out from the shower discharge port 12a or the straight discharge port 12b.
[0106]
First, when the push button 13 has a shallow push amount, the raw water-side shut-off valve 16 is closed, and the purified water-side shut-off valve 17 is open so that the purified mixed water flows out, the push button 13 is made deep. When pushed in, the shutoff valve 16 is opened, the shutoff valve 17 is closed, and switching to discharge of raw water is performed. When the push button 13 is pushed again from this state and the push button 13 is changed to a shallow push amount, the shutoff valve 16 is closed and the shutoff valve 17 is opened to switch to discharge of purified water.
[0107]
At the time of discharge of purified water, it passes through the valve seat 17a of the shut-off valve 17 and flows out to the valve downstream side flow path 20 formed by the purified water conduit 65 and the flow path forming member 313a of the partition member 313, and raw water through the opening 313c. Cylinder that protrudes from the valve downstream side channel 320 through the purified water channel 319a and from the head 12 through the purified water side valve downstream channel 320 formed along the outer periphery of the valve downstream space 18 It discharges from the purified water discharge port 319 projected in the part 11a.
[0108]
Further, at the time of discharging raw water, similarly to the case of the first embodiment, it passes through the valve seat 16a of the shutoff valve 16 and flows out into the valve downstream side space 18, and from the valve downstream side space 18 through the collecting passage 25. The shower discharge or straight discharge selected by the switching lever 14 is performed.
[0109]
In this case, when shower discharge is performed, when the switching lever 14 is operated to rotate the valve body 26a around the shaft portion 26b independently of the operation of the push button 13, the valve body 26a is moved to the straight discharge port. The raw water coming off from the inlet portion of 12b and flowing out of the collecting passage portion 25 flows into the inlet portion of the straight discharge port 12b and is discharged straight.
[0110]
Further, when the straight discharge is performed, the switching lever 14 is operated in the opposite direction to rotate the valve body 26a in the reverse direction about the shaft portion 26b, so that the valve body 26a is brought into the inlet portion of the straight discharge port 12b. The raw water entering and flowing out from the collecting passage 25 is prevented from flowing into the inlet of the straight outlet 12b, the flow path is changed to the shower side space 314, and the shower side space 314 is passed through the shower outlet 12a. The shower comes out.
[0111]
In such a 3rd Example, since the purified water discharge port 319 is provided in the cylinder part 11a of the holding part 11, distinction with purified water discharge and raw | natural water discharge can be performed easily, and discharge switching is performed in purified water discharge. Since the discharge can be performed without any problems and the operability is improved, the distinguishability, visibility and operability are improved.
[0112]
Further, since the raw water shut-off valve 16 and the water purifying shut-off valve 17 of the flow path switching valve are alternately switched shut-off valves for alternately shutting off the flow path by the same push button 13, it protrudes from the head 12. By pressing the push button 13, the purified water and the raw water can be switched and used, and the operability can be further improved.
[0113]
Moreover, since the shut-off valve 16 for raw water and the shut-off valve 17 for purified water are spherical valve bodies 16b and 17b, respectively, the water pressure applied to the spherical valve bodies 16b and 17b when the valves are closed is as follows: Together with the urging force of the coil springs 16d and 17d, the spherical valve bodies 16b and 17b act so as to be pressed against the valve seats 16a and 17a, and can be reliably sealed.
[0114]
Since the discharge switching valve 26 is formed in a flow path provided downstream of the raw water side shut-off valve 16 among the flow path switching valves, the raw water side shut-off valve 16 is opened. In this case, either shower discharge or straight discharge can be selected, and high convenience can be given regarding the use of raw water.
If the inflow path to the flow path switching valve is changed so that the shutoff valve 16 is the purified water side and the shutoff valve 17 is the raw water side, the purified water side can be configured to be switchable between shower discharge and straight discharge.
[0115]

[Function and effect]
In the fifth embodiment configured as described above, the push button 13 incorporated in the head 12 is operated to purify the push button 13 protruding from the head 12 (shallow push amount). In a state where the mixed water flows out from the purified water discharge port 12b and the push button 13 enters the head 12 and the amount of protrusion is small (deep push amount), the raw water flows out from the shower discharge port 12a.
[0147]
First, when the push button 13 has a shallow push amount, the raw water side shut-off valve 16 is closed, the purified water shut-off valve 17 is open, and the purified mixed water flows out, the push button 13 is pushed deep. The shut-off valve 16 is opened, the shut-off valve 17 is closed, and the raw water is switched to discharge. When the push button 13 is pushed again from this state and the push button 13 is changed to a shallow push amount, the shutoff valve 16 is closed and the shutoff valve 17 is opened to switch to discharge of purified water.
[0148]
At the time of discharging the purified water, the purified mixed water passes through the valve seat 17a of the shutoff valve 17 and flows out to the valve downstream side flow path 520 formed by the purified water conduit 565, and the water guide pipe 562 through the collecting passage 25. Flows out into the purified water flow path 519 formed by the water, passes through the purified water flow path 519, and is discharged from the purified water discharge port 12b.
[0149]
When discharging the raw water, as shown in FIGS. 91 to 93, the shutoff valve 17 is closed, the shutoff valve 16 is opened, and the mixed water passes through the valve seat 16a of the shutoff valve 16 and flows into the valve downstream space 18.

[0150]
In the fifth embodiment, since the purified water discharge port 12b forms a straight discharge port and the raw water discharge port 12b forms a shower discharge port, it is easy to distinguish between purified water discharge and raw water discharge. In the clean water discharge, the discharge can be performed without switching the discharge and the operability is improved, so that the discrimination, visibility and operability are improved.
[0151]
Further, the raw water shut-off valve 16 and the purified water shut-off valve 17 of the flow path switching valve are alternately switched shut-off valves that alternately shut off the flow path by the same push button 13, and the raw water / purified water discharge Since the push-in position of the push button 13 is different, the push button 13 protruding from the head 12 can be used without mixing the clean water and raw water, and the operability can be further improved. .
[0152]
Moreover, since the shut-off valve 16 for raw water and the shut-off valve 17 for purified water are spherical valve bodies 16b and 17b, respectively, the water pressure applied to the spherical valve bodies 16b and 17b when the valves are closed is as follows: Together with the urging force of the coil springs 16d and 17d, the spherical valve bodies 16b and 17b act so as to be pressed against the valve seats 16a and 17a, and can be reliably sealed.
