【発明の属する技術分野】
本発明は、本発明者が２００３年２月１２日に新出願した特願２００３−３３０３５号の浴槽湯口装置の更に改良に関する。
【０００２】
【従来の技術】
特願２００３−３３０３５号に示されている浴槽湯口装置は、その装置の図１に示すように、金網ストレーナ４０、前記金網ストレーナ４０内に収納される浴槽湯口装置１０、前記浴槽湯口装置１０に接続されるフランジ付き雄ねじ筒２０、前記フランジ付き雄ねじ筒２０に接続される給湯通路及び戻湯通路の金具３０、前記給湯通路及び戻湯通路の金具３０に連結する給湯配管及び戻湯配管、前記給湯配管及び戻湯配管に連結する循環風呂釜装置において、前記浴槽湯口装置１０が、前記給湯通路及び戻湯通路の金具３０の給湯通路３１に連通する前記フランジ付き雄ねじ筒２０内の第１湯管１４の前端に接続する第１筒１１であって、筒側面に出口１１０を形成したものを設け、前記給湯通路及び戻湯通路の金具３０の戻湯通路３２に連通する前記フランジ付き雄ねじ筒２０の内筒２５及び第２湯管１５の前端に接続する第２筒１２であって、筒側面に出口１２０を形成したものを設け、前記第１筒１１の出口１１１が開いて前記第２筒１２の出口１２１を閉じるか又は、前記第１筒１１の出口１１１を閉じて前記第２筒１２の出口１２１を開くようにしたシーソ状弁板１３を設け、追いだき運転時には、前記第１筒１１の出口１１１を開いて前記第２筒１２の出口１２１を閉じて給湯し、戻湯を前記第２筒１２の出口１２０から流入させるか、前記第２筒１２の出口１２１を開いて前記第１筒１１の出口１１１を閉じて給湯し、戻湯を前記第１筒１１の出口１１０から流入させてなり、前記給湯通路及び戻湯通路の金具３０の接続口３１１、３２１が前記給湯配管又は前記戻湯配管のいずれにも連結できるようにしていたが、追いだき運転時に、第１筒１１の出口１１１から給湯の際、第１筒１１の出口１１０からの横もれ量が、又は、第２筒１２の出口１２１から給湯の際、第２筒１２の出口１２０からの横もれ量が少なくなく、給湯の量が少なくなる恐れがあった。
そこで、本発明者は、図１に示すように、パイプ１１（１３）の一端１５（１６）から流入した給湯は、他端１１１（１３１）が弁１０１により開放されているときは、途中に小穴１１０１（１３０１）を介して別のパイプ１２又は１４の出口１２０（１４０）に通じていても、小穴１１０１（１３０１）から殆ど流出することなく、出口１１１（１３１）に流出して給湯でき、出口１１１（１３１）を弁１０１で閉じたとき、別のパイプの出口１２０（１４０）から戻湯が流入し、小穴１１０１（１３０１）を通じて流れて、追だき運転が更に円滑にできることを見出した。
また、本発明者は、本発明者が２００３年３月３日に出願した特願２００３−５６１５２号の浴槽湯口装置の図６、図７及び図８に示されているように、浴槽湯口装置１０の側面に雄ねじ筒２０のフランジ２１に係合する係合具５０又は５０Ｂ又は５０Ｃを設けて係合するようにしていたが、係合具の可撓片の反発力でフランジ２１が上方へ押し上げられているため、図５の弾性突条２６が常に圧迫されて摩耗が生じ、浴槽湯口装置１０と雄ねじ筒２０の接続がゆるくなる恐れがあった。
そこで、本発明者は、浴槽湯口装置をフランジ付雄ねじ筒に接続する際に、係合具で係合する代わりに、フランジ部に挟着できるようにした挟着具を設けて接続することにより、上記恐れを回避することに成功した。
【０００３】

さらに、本発明は、部品数が少なく、小型化でき、大幅な製作コストの削減をはかることができる浴槽湯口装置を提供するものである。
【０００４】
【課題を解決するための手段】
本発明浴槽湯口装置は、上記課題を達成するため、図示するように、金網ストレーナ４０、前記金網ストレーナ４０内に収納される浴槽湯口装置１０、前記浴槽湯口装置１０に接続されるフランジ付き雄ねじ筒２０、前記フランジ付き雄ねじ筒２０に接続される給湯通路及び戻湯通路の金具３０、前記給湯通路及び戻湯通路の金具３０に連結する給湯配管及び戻湯配管、前記給湯配管及び戻湯配管に連結する循環風呂釜装置において、前記浴槽湯口装置１０が、前記給湯通路及び戻湯通路の金具３０の給湯通路３１に連通する前記フランジ付き雄ねじ筒２０の内筒２５内に挿入された第１湯管１５の前端に第１筒１１を接続し、前記第１筒１１の中途の出口１１０１から先端１２０１を閉塞した第２筒１２の出口１２０を連通し、前記給湯通路及び戻湯通路の金具３０の戻湯通路３２に連通する前記フランジ付き雄ねじ筒２０の内筒２５に接続する第２湯管１６の前端に第３筒１３を接続し、前記第３筒１３の中途の出口１３０１から先端１４０１を閉塞した第４筒１４の出口１４０を連通し、前記第１筒１１の出口１１１が開いて前記第３筒１３の出口１３１を閉じるか、又は、前記第１筒１１の出口１１１を閉じて前記第３筒１３の出口１３１を開くようにしたシーソ状弁板１９を設け、追いだき運転時には、前記第１筒１１の出口１１１を開いて前記第３筒１３の出口１３１を閉じて給湯し、戻湯を前記第４筒１４の出口１４０から流入させるか、前記第３筒１３の出口１３１を開いて前記第１筒１１の出口１１１を閉じて給湯し、戻湯を前記第２筒１２の出口１２０から流入させてなり、前記給湯通路及び戻湯通路の金具３０の接続口３１１、３２１が前記給湯配管又は前記戻湯配管のいずれにも連結できるようにしたものである。
また、本発明浴槽湯口装置は、上記課題を達成するため、図示するように、前記浴槽湯口装置１０が、前記フランジ付き雄ねじ筒２０と接続するために、前記浴槽湯口装置１０の側面に雄ねじ筒２０のフランジ２１を挟着できるように形成した挟着具５０を１ケ所又は２ヶ所以上設けたものである。
本発明の原理を図１により説明すると、追だき運転時は、循環風呂釜装置（図示しない）から給湯配管（図示しない）を介して、金具３０の接続口３１１及び給湯通路３１を通じて流入した給湯は、第１湯管１５を経て第１筒１１の出口１１１から流出して金網ストレーナ４０の側面から浴槽内に流出する。このとき第１筒１１の中途の出口１１０１から連通した先端１２０１を閉鎖した第２筒１２の出口１２０からは殆ど流出しない。これに対し、浴槽内の戻湯は金網ストレーナ４０の前面及び側面から出口１４０に流入して先端１４０１が閉鎖された第４筒１４の中途の出口１３０１からシーソ弁板１９により出口１３１が閉鎖された第３筒１３を通じて第２湯管１６を経て、金具３０の戻湯通路３２及び接続口３２１から戻り湯配管（図示しない）を介して循環風呂釜装置（図示しない）に流入することになる。
また、循環風呂釜装置（図示しない）から給湯配管（図示しない）を介して、金具３０の接続口３２１及び戻湯通路３２に接続した場合は、給湯は、第２湯管１６を経て第３筒１３の出口１３１からシーソ弁板１９を開いて流出し金網ストレーナ４０の側面から浴槽内に流出する。このとき第３筒１３の中途の出口１３０１から連通した先端１４０１を閉鎖した第４筒１４の出口１４０からは殆ど流出しない。これに対し、浴槽内の戻湯は金網ストレーナ４０の前面及び側面から出口１２０に流入して第２筒１２の中途の出口１１０１からシーソ弁板１９により出口１１１が閉鎖された第１筒１１から第１湯管１５を経て、金具３０の給湯通路３１及び接続口３１１から戻湯配管（図示しない）を介して循環風呂釜装置（図示しない）に流入することになる。
すなわち、本発明では、給湯配管又は戻湯配管を、給湯通路及び戻湯通路を形成する金具３０の接続口３１１又は３２１のいずれに接続しても、常に、金網ストレーナ４０の側面から給湯が流出し、前面及び側面から戻湯が流入することになる。
【０００５】
【発明の実施の形態】
本発明の実施の形態が図１乃至図８に示されている。
図２及び図３に示すように、本発明装置を含む全体装置は、金網ストレーナ４０、前記金網ストレーナ４０内に収納される浴槽湯口装置１０、前記浴槽湯口装置１０に接続されるフランジ付き雄ねじ筒２０、前記フランジ付き雄ねじ筒２０に接続される給湯通路及び戻湯通路の金具３０、前記給湯通路及び戻湯通路の金具３０に連結する給湯配管及び戻湯配管（図示しない）、前記給湯配管及び戻湯配管に連結する循環風呂釜装置（図示しない）からなっている。
金網ストレーナ４０は、ステンレス板をトレイ状に成型して前面にメッシュ窓４１を打ち抜いたもので、フランジ付き雄ねじ筒２０のフランジ２１の上半に外嵌させて係合させると共に、２個の円柱突起４２、４２を浴槽湯口装置１０の前面１００に設けた直線状突起１８の下方に係合できるように形成されている。
浴槽湯口装置１０は、第１筒１１と第２筒１２と第３筒１３と第４筒１４と、図４及び図５に示すように、第１筒１１と連通するように連設した第１湯管１５と、第３筒１３に連通するように連設すると共に、第１湯管１５の外周面に沿って設けた第２湯管１６とからなっている。第１筒１１には中途の出口１１０１から先端１２０１を閉塞した第２筒１２の中途の出口１１０１に連通し、第３筒１３には中途の出口１３０１から先端を閉塞した第４筒１４の中途の出口１３０１に連通している。
また、第２湯管１６の外周面後端には多数の細かい山形突条１７を形成している。
また、挟着具５０は、浴槽湯口装置１０の外側面１０１又は１０２から延設した把手板５１と、その断面Ｌ型の先端の内側に丸めた接触部分５２が、雄ねじ筒２０のフランジ２１を挟着できるように設けられている。また、把手板５１の先端には接触部分５２を開くつまみ５３が延設されている。
フランジ付き雄ねじ筒２０は、図６に示すように、フランジ２１と、筒外周面の雄ねじ２２と、内周面２３の前端に刻設した多数の細かい山形突条２４であって前記第２湯管１６の外周面に形成した山形突条１７に外嵌して噛合するものと、浴槽湯口装置１０の第２湯管１６と連通する湯筒２５とを設けている。
給湯通路及び戻湯通路の金具３０は、第１湯管１５に外嵌して連通する内筒部３０１と、雄ねじ筒２０の雄ねじ２２に外嵌してめねじ３５で螺合し、湯筒２５と連通する外筒部３０２と、給湯配管（図示しない）に接続する給湯通路３１及び接続口３１１と戻湯配管（図示しない）に接続する戻湯通路３２及び接続口３２１とゴムパッキン３４を外嵌したフランジ部３３とを設けている。
従って、追だき運転時には、図２及び図３に示すように、循環風呂釜装置（図示しない）から給湯配管（図示しない）を介して、金具３０の接続口３１１及び給湯通路３１を通じて流入した給湯は、第１湯管１５を経て第１筒１１の出口１１１から流出して金網ストレーナ４０の側面から浴槽内に流出する。このとき第１筒１１の中途の出口１１０１から連通した第２筒１２の出口１２０からは殆ど流出しない。また、第１湯管１５を経て第１筒１１の出口１１１から金網ストレーナ４０の側面より流出する給湯は、途中に従来のような往復動体や屈曲流路がないので大容量で流出する。浴槽内の戻湯は、金網ストレーナ４０の前面及び側面から出口１４０に流入して第４筒１４の中途の出口１３０１からシーソ弁板１９により出口１３１が閉鎖された第３筒１３から第２湯管１６及びフランジ付き雄ねじ筒２０の内筒２５を経て、金具３０の戻湯通路３２及び接続口３２１から戻り湯配管（図示しない）を介して循環風呂釜装置（図示しない）に流入し循環することになる。
なお、循環風呂釜装置（図示しない）から給湯配管（図示しない）を、金具３０の接続口３２１及び戻湯通路３２に接続した場合は、追だき運転時の給湯は、フランジ付き雄ねじ筒２０の内筒２５から第２湯管１６を経て、第３筒１３の出口１３１からシーソ弁板１９を開いて流出し、金網ストレーナ４０の側面から浴槽内に前述した理由により大きな流量で流出する。このとき第３筒１３の中途の出口１３０１から連通した第４筒１４の出口１４０からは殆ど流出しない。また、浴槽内の戻湯は金網ストレーナ４０の前面及び側面から出口１２０に流入して第２筒１２の中途の出口１１０１からシーソ弁板１９により出口１１１が閉鎖された第１筒１１から第１湯管１５を経て、金具３０の給湯通路３１及び接続口３１１から戻湯配管（図示しない）を介して循環風呂釜装置（図示しない）に流入し循環することになる。
本発明装置１０をフランジ付き雄ねじ筒２０に取りつけるときは、本発明装置１０の円周状の山形突条１７を、フランジ付き雄ねじ筒２０の山形突条２４に噛合するように嵌入して、図７に示すように、本発明装置１０の側面の挟着具５０、５０の把手板５１と接触部分５２とを雄ねじ筒２０のフランジ２１に挟着するように押し込めば、本発明装置１０とフランジ付き雄ねじ筒２０とは迅速に固着できる。その際、本発明装置１０はフランジ付き雄ねじ筒２０とどのような方向にも噛合して嵌着できる。
また、本発明装置１０のつまみ５３、５３を押せば接触部５２、５２が開いて雄ねじ筒２０のフランジ２１の外周面から離れるようになり、本発明装置１０をフランジ２１から離脱できる。
【０００６】
【発明の効果】
以上のように、本発明によれば、お湯張り及び追だき運転時には、大流量で浴槽に迅速に給湯することができると共に、循環風呂釜装置の給湯配管及び戻湯配管を給湯通路及び戻湯通路の金具のいずれの接続口に連結しても、浴槽の給湯は常に金網ストレーナの側面から行い、戻湯は常に金網ストレーナの前面及び側面から行うことができ安全を確保できることになる。
また、本発明によれば、浴槽湯口装置は極めて簡単な構造で済み、部品数も少なく故障が発生する恐れも全くなく、安価に製作できる利点がある。その上、本発明浴槽湯口装置をフランジ付き雄ねじ筒に接続するには、ビス止めや係着具で係着する場合に比べて、雄ねじ筒にそのまま嵌入するだけで済み、作業の大幅な簡単化能率化を図ることができるなど画期的な効果を発揮できることになった。
