【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】
〔従来技術の問題点〕
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】

【００１１】
【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、流路切換と吐出切換とを同一の切換弁によって行う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。
【００１２】
〔構成〕
この実施の形態における浄水機能付きシャワーヘッドは、水、湯または湯水混合水（以下、単に混合水という）を吐出する混合水栓を有する台所の流しで使用されるもので、図１，２に示すように、外観上は操作部として特別な突出部分がなく、一見、操作部が設けられていないかのような形状に形成されており、頭部のシャワー吐出面側の端部を操作することによって原水と浄水との流路切換ならびにストレートとシャワーとの吐出状態の切換を同一回動式操作部を操作することによって行えるようにした回動式の切換弁を組み込んだ構成にしている。
【００１３】
この浄水機能付きシャワーヘッド１００は、水質浄化用カートリッジ（図示せず）を交換可能に収容したシャワーヘッドとして利用できるようにするため、筒部１１と筒部１２とに分離できるように形成するとともに混合水栓のホースに螺合するためのねじ１４を設けた端部１３を形成した把持部１０１と、この把持部１０１のホース取付側とは反対側の端部にストレート吐出口２１およびシャワー吐出口２２を一体的に設けた頭部１０２とを備える。
【００１４】
把持部１０１は、中間部で頭部１０２側に一体化した筒部１１とホース取付側の筒部１２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１５を設け、この中継用ねじ部１５の螺合を解除して筒部１１と筒部１２を分離することにより、把持部１０１の内部に水質浄化用カートリッジ１０３（図３，４参照）を収容することができるようにする。
【００１５】
頭部１０２には、中央部にストレート吐出口２１を形成し、その周囲を取り囲むようにシャワー吐出口２２を形成し、そのシャワー吐出口２２を形成する部材の周縁を立ち上がらせて、吐出口を回動するための操作部として利用する外周側下端部２３を形成する。
【００１６】
浄水機能付きシャワーヘッド１００は、図３，４に示すように、把持部１０１の内部に水質浄化用カートリッジ１０３を収容する。
この水質浄化用カートリッジ１０３を収容した把持部１０１では、水質浄化用カートリッジ１０３の外周側流路３１を原水流路の一部とし、水質浄化用カートリッジ１０３の中央空間部３２を浄水流路の一部として利用する。
【００１７】
水質浄化用カートリッジ１０３は、中心軸と同心的に孔（中央空間部３２）を設けて円筒状に形成した水質浄化材３４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３５，３６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３７とを、３つに分割したキャップ４１，４２，４３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。
【００１８】
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４１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４１，４３との嵌合部を形成したキャップ４２とにより形成される空間に、水質浄化材３４を収容する。
【００１９】
また、キャップ４２は異径の２つの円筒を中心軸に対して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４２との嵌合部を形成し、小径側の円筒には頭部１０２側に設けた（後述の）カートリッジ受け４４との嵌合部を形成したキャップ４３により形成された、大径側の円筒の内部空間に、フィルタ３５，３６に挟持された殺菌セラミック３７を収容する。
【００２０】
キャップ４１とキャップ４２が形成する空間に収容される水質浄化材３４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。
【００２１】
また、キャップ４３の大径側の円筒内に収容される殺菌セラミック３７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。
【００２２】
把持部１０１の筒部１１の内部には、水質浄化用カートリッジ１０３の先端部（キャップ４３の小径側の端部）を差し込み、固定するための円筒状のカートリッジ受け４４を頭部１０２側の表面から突設する。
このカートリッジ受け４４に水質浄化用カートリッジ１０３のキャップ４３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１０３が位置固定される。
キャップ４３の小径側の端部には周面にＯリング４５が周設され、端部がカートリッジ受け４４に差し込まれた場合にカートリッジ受け４４の内周面に密接するＯリング４５により漏れが止められる。
【００２３】
そして、カートリッジ受け４４の外周側流路４６が、水質浄化用カートリッジ１０３の外周側流路３１と連通して把持部１０１内の原水流路として利用され、さらにカートリッジ受け４４の内面側流路４７が水質浄化用カートリッジ１０３の中央空間部３２と殺菌セラミック３７を介して連通することにより把持部１０１内の浄水流路として利用される。
【００２４】
これにより、浄水吐出の場合には、把持部１０１内に流入した混合水が、水質浄化用カートリッジ１０３の外周側流路３１から水質浄化用カートリッジ１０３の水質浄化材３４を通過して水質を浄化し、水質浄化材３４の中央空間部３２に流出して引き続きフィルタ３６、殺菌セラミック３７、フィルタ３５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４４の内面側流路４７を介して頭部１０２側に流出し、頭部１０２から外部へ吐出する。
【００２５】
また、原水吐出の場合には、水質浄化用カートリッジ１０３の外周側流路３１を通過し、カートリッジ受け４４の外周側流路４６を介して頭部１０２側に流出し、頭部１０２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１０３の外周側流路３１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３４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。
【００２６】
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３４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させて、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。
【００２７】
頭部１０２の内部には、図３〜６に示すように、略上半部には把持部１０１内の原水流路と接続する頭部１０２内の原水流路２４、および、把持部１０１内の浄水流路と接続する頭部１０２内の浄水流路２５が形成され、その略下半部にはシャワー吐出口２２の外周側下端部２３を操作部として利用する回動式の切換弁１０５が組み込まれる。
【００２８】
回動式の切換弁１０５は、頭部１０２に固着される固定仕切部材５１と、この固定仕切部材５１に回動自在に組付けた回動部材５２とからなり、回動部材５２に設けられた外周側下端部２３を操作することによって、原水と浄水との流路切換ならびにストレートとシャワーとの吐出切換を行わせることができるようにする。
【００２９】
固定仕切部材５１は、頭部１０２内に固着し、原水と浄水との流路を仕切るとともに原水と浄水との吐出流路側への流出口を各別に穿設し、回動部材５２側に設けた各流入口との間で回動部材５２の回動に従って組み合わされ、吐出水と吐出流路との所定の組合せが選択される。
この固定仕切部材５１は、円盤状の仕切板６１の中央部に突出貫通した軸部材６２と、この軸部材６２を含めた径方向の直線上に軸部材６２に対して同一方向に並べて配置した浄水流出口６３と原水流出口６４とを穿設し、回動部材５２が所定の位置に回動されたときにクリック感を与えるとともに位置ずれを起こさないように位置固定する突起収容部６５を突設する。
【００３０】
浄水流出口６３と原水流出口６４とには、それぞれ、ばね６６に付勢されて回動部材５２に当接し、回動部材５２側の各開口との間の間隙を大きく開けないようにする開口当接部材６７を内蔵する。
また、突起収容部６５には、ばね６８に付勢された係止部材６９を収容して、回動部材５２の回動時における回動部材５２側に設けられた各凹部８８（図１３参照）への係止部材６９の落ち込みによるクリック感を与えるとともに、固定仕切部材５１と回動部材５２とが相対的に位置ずれしないように位置固定する。
【００３１】
回動部材５２は、全体形状を両端に蓋をした浅い二重円筒形に形成し、固定仕切部材５１の浄水流出口６３または原水流出口６４から流出する混合水を、それぞれストレート吐出口２１とシャワー吐出口２２とのいずれかに導く流路を内部に形成する。
【００３２】
この回動部材５２は、固定仕切部材５１の軸部材６２に回動自在に軸着する軸着部材７１と、この軸着部材７１の下端面でストレート吐出口２１の外周側にシャワー吐出口２２を設けるシャワー吐出面を形成するとともにこのシャワー吐出面の周辺部に回動部材５２の操作部となる外周側下端部２３を形成するシャワープレート７２と、シャワープレート７２の中央部に嵌め込まれてストレート吐出口２１およびストレート吐出口２１への流路を形成するストレート吐出面形成部材７３とからなる。
【００３３】
そして、この回動部材５２では、固定仕切部材５１の軸部材６２に軸着する軸着部材７１の軸部材６２への嵌着部周辺にストレート吐出流路７４を形成し、そのストレート吐出流路７４の外周側に円筒状中間仕切壁７５を介してシャワー吐出流路７６を同心的に形成する。
【００３４】
ストレート吐出流路７４は、回動部材５２の軸着部材７１に設けられた嵌着部７７と円筒状中間仕切壁７５との間に形成された空間で、軸着部材７１の上壁には嵌着部７７と円筒状中間仕切壁７５との中間位置に固定仕切部材５１の浄水流出口６３の配置位置に合わせて穿設されて浄水用のストレート吐出用案内流路８３に連通する開口８１が開設され、また上壁の円筒状中間仕切壁７５よりも外側の位置には固定仕切部材５１の原水流出口６４の配置位置に合わせて穿設されて原水用のストレート吐出用案内流路８７に連通する開口８５が開設されて、浄水と原水との両方の流路として兼用されるストレート吐出用の流路を形成する。
【００３５】
このストレート吐出流路７４は、上流側では混合水が開口８１，８５からストレート吐出用案内流路８３，８７を介して流入し、下流側では接続する集合通過部２６を介してストレート吐出面形成部材７３の内部に形成された流路に流出し、この流路を経てストレート吐出口２１から吐出するようにした中間案内流路を形成する。
【００３６】
シャワー吐出流路７６は、回動部材５２の軸着部材７１に設けられた円筒状中間仕切壁７５と外周壁７８との間に形成された空間で、軸着部材７１の上壁には嵌着部７７と円筒状中間仕切壁７５との中間位置に固定仕切部材５１の浄水流出口６３の配置位置に合わせて開口８１と軸対称な位置に穿設されて浄水用のシャワー吐出用案内流路８４に連通する開口８２が開設され、また上壁の円筒状中間仕切壁７５よりも外側の位置には固定仕切部材５１の原水流出口６４の配置位置に合わせ開口８５と軸対称な位置に穿設された開口８６が開設されて、浄水と原水との両方の流路として兼用されるシャワー吐出用の流路を形成する。
【００３７】
このシャワー吐出流路７６は、上流側では原水が直に連通した開口８６から直接流入し、また浄水は開口８２からシャワー吐出用案内流路８４を介して流入し、下流側では軸着部材７１の下端に嵌着されたシャワープレート７２に穿設されたシャワー吐出口２２，…，２２から直に吐出するようにした中間案内流路を形成する。
【００３８】
切換弁１０５を収容する頭部１０２は、図７〜９に示すように、吐出側に切換弁１０５を収容する主要部が有蓋円筒形の外皮２７を形成し、この外皮２７の把持部側には筒部１１が突出し、その突出した筒部１１の内側にカートリッジ受け４４を略同心に突出し、その外皮２７の円筒中心に対して同心的に小径の薄肉円筒を頂部内面から垂下して原水流路と浄水流路とを分ける隔壁２８を形成し、その隔壁２８の周面に一端を結合してカートリッジ受け４４から隔壁２８までの間を連通する中継隔壁２９を形成する。
【００３９】
隔壁２８の内側は中継隔壁２９を介してカートリッジ受け４４の内面側流路４７と連通した浄水流路となり、外側がカートリッジ受け４４の外周側流路４６と連通する原水流路となる。
隔壁２８の下側には切換弁１０５の固定仕切部材５１が嵌着して頭部１０２を密封し、頭部１０２に流入した混合水を切換弁１０５の動作に従い原水と浄水のいずれかをストレート吐出口２１かシャワー吐出口２２のいずれかより吐出する。
【００４０】
固定仕切部材５１は、図１０〜１２に示すように、仕切板６１の端縁に頭部１０２への嵌合用の浅い円筒部６１ａを軸方向に立設し、仕切板６１には中央部に貫通した有底円柱状の軸部材６２を軸方向に突出し、その軸部材６２の下流側の端面に軸方向に深く孔６２ａを穿設し、仕切板６１の上流側の面には軸部材６２の突出位置から径方向外側に浄水流出口６３を設け、軸部材６２と浄水流出口６３とを含む直線上にあって軸部材６２に対し浄水流出口６３と同一側で端縁近傍に寄った位置に原水流出口６４を穿設し、さらに軸部材６２と流出口６３，６４とを含む直線上にあって軸部材６２に対し流出口６３，６４とは反対側に突起収容部６５を突出し、仕切板６１の上流側の面には軸部材６２と同心的に頭部１０２の隔壁２８に内嵌する原水流路と浄水流路との隔壁６１ｂを立設する。

【００４８】
シャワープレート７２は、図１７に示すように、中央部が開口され、その開口端縁にはストレート吐出面形成部材７３を嵌め込むことができるようにするとともに円筒状中間仕切壁７５に外嵌するための内径を有する浅い円筒部７２ａを内面側に突設し、外周端には円筒部７２ａと同一方向に突出するとともに内径を軸着部材７１に設けられた外周壁７８の下端部外径に嵌合するための大きさを有する浅い円筒状の外周側下端部２３を形成し、円筒部７２ａと外周側下端部２３との間に位置する平板部７２ｂにはシャワー吐出口２２を多数個につき略均等に穿設する。
【００４９】
このシャワープレート７２の円筒部７２ａには、軸着部材７１に嵌合したときの回止め用に矩形状の突起７２ｃを上端面から突出し、円筒状中間仕切壁７５に設けられた突出部７５ｂの切欠き７５ｃに係合して回止めすることができるように形成する。
円筒部７２ａの高さは円筒状中間仕切壁７５に設けられた突出部７５ｂに当接するまでに必要な寸法以下であれば良く、また、外周側下端部２３の高さは嵌合する相手部材の嵌合位置における高さに応じて規定し、その範囲で頭部１０２の外皮２７の下端に当接しないで済む寸法にする。
【００５０】
集合通過部２６は、図１８に示すように、有底円筒の底板部２６ａに外周側の下端部が外部と部分的に貫通する多数の光芒を有する環状の溝２６ｂを軸方向に深く刻設し、底板部２６ａの側方を円筒部の外径よりも小さく形成して、溝２６ｂの側方を開口した形状に形成する。
この集合通過部２６の外形は上部に浅い円筒部２６ｃを有し、この円筒部２６ｃをストッパとしてストレート吐出面形成部材７３の集合通過部嵌合箇所に嵌め込むことができる外径に形成し、底板部２６ａの下方に突出した中央部を集合通過部嵌合箇所に形成されている下方に縮径するコーン部９１ｃ（図１９参照）に位置するように軸方向の寸法を調節する。

[0016]
As shown in FIGS. 3 and 4, the shower head 100 with the water purification function houses a water purification cartridge 103 inside the grip portion 101.
In the gripping part 101 that accommodates the water purification cartridge 103, the outer peripheral flow path 31 of the water purification cartridge 103 is a part of the raw water flow path, and the central space 32 of the water purification cartridge 103 is a part of the water purification flow path. Use as part.
[0017]
The water purification cartridge 103 has a water purification material 34 formed in a cylindrical shape by providing a hole (central space portion 32) concentrically with the central axis, and filters 35, 36 made of nonwoven fabric, sponge, mesh, or the like on the downstream side. The sterilizing ceramic 37 in the form of granules or pellets sandwiched between the two is accommodated in two spaces formed by caps 41, 42, 43 divided into three parts.
[0018]
And it has the cap 41 formed in the bottomed cylindrical shape which provided many slits in the surrounding wall, and the water purification material support wall of the surface perpendicular | vertical to the axial direction which pierced the hole used as a fluid passage in the center part of a cylindrical shape. Thus, the water purification material 34 is accommodated in a space formed by a cap 42 in which a fitting portion with other caps 41 and 43 is formed at each end.
[0019]
The cap 42 connects two cylinders with different diameters by a wall surface perpendicular to the central axis, and a fitting portion with the cap 42 is formed on the larger diameter cylinder of the two cylinders, thereby reducing the smaller diameter cylinder. The sterilization sandwiched between the filters 35 and 36 in the inner space of the large-diameter side cylinder formed by a cap 43 formed with a fitting portion with a cartridge receiver 44 (described later) provided on the head 102 side. A ceramic 37 is accommodated.
[0020]
The water purification material 34 accommodated in the space formed by the cap 41 and the cap 42 is made of activated carbon as a main component and hardened in a cylindrical shape, and mixed water permeates between the cylindrical outer peripheral surface and the center hole. During the process, chemical components dissolved in water and fine solid substances floating are adsorbed or filtered.
