【０００２】
【従来の技術】
湯水混合栓の一つとして、混合栓本体に給水管および給湯管を連結し、例えば台所の流し台の水栓取付板部に開設された一つの貫通孔に前記給水管および給湯管を挿通させることにより、水栓取付板部の上面へ混合栓本体が設置される、いわゆる、ワンホールタイプの混合栓がある。前記給水管および給湯管は、混合栓本体内に設けた水流入孔および湯流入孔にそれぞれ接続されている。
【０００３】
【発明が解決しようとする課題】
ところで、食器洗い乾燥機において洗いやすすぎに使用する湯の最高温度は、７０℃ぐらいまでとなっており、前記ワンホール混合栓の混合栓本体内の水流入孔および湯流入孔下流にサーモバルブ（ミキシングバルブ）を設け、更に、このサーモバルブの下流に混合湯水の分岐流路を設け、サーモバルブによって７０℃ぐらいまでに温度管理された混合湯水を分岐流路を介して食器洗い乾燥機へ流出させることが考えられるが、サーモバルブは大変高価である。
【０００４】
この発明は、上記問題に鑑みてなしたもので、コストダウンを実現できるとともに、食器洗い乾燥機への７０℃以上の高温水の流出を防止できるワンホール型湯分岐混合栓を提供することを目的とする。
【０００５】
【課題を解決するための手段】
上記目的を達成するために、この発明は、湯水の混合比の調節および止水を含む吐水量の調節を行うための操作レバーと混合湯水の吐水管とを備えた湯水の混合栓本体の胴内に設けた水流入孔および湯流入孔にそれぞれ接続された給水管および給湯管を台所の流し台等の水栓取付板部に開設された一つの貫通孔に挿通させた状態で前記混合栓本体を前記水栓取付板部に取付けるとともに、前記給湯管を通って前記湯流入孔に流入した湯の一部を操作ハンドルを操作することにより湯分岐流路へと分岐させこの湯分岐流路をホースを介して直接食器洗い乾燥機の湯入口に連通させるための湯分岐バルブを前記混合栓本体に設けるとともに、所定温度以上の熱水が前記食器洗い乾燥機に流出するのを防止する熱水防止弁を前記湯分岐流路に設けてあるワンホール型湯分岐混合栓であって、
前記胴は、胴前面側から突出した状態で吐水管直下に設けられた膨出部を有し、この膨出部の一端には、前記熱水防止弁を装着したニップルが内蔵される一方、前記湯分岐バルブが前記膨出部の他端に設けられており、
また、前記湯分岐バルブは、前記ニップルの中心線の延長線上に設けられた操作ハンドル装着可能な栓棒と、前記操作ハンドルの操作に連動して開閉する弁体を有することを特徴とする。
【０００６】
【発明の実施の形態】
以下にこの発明の実施の形態について説明する。なお、この発明はそれによって限定されるものではない。
【０００７】
図１〜図４において、１は、操作レバー３および混合湯水の吐水管２を備えた湯水の混合栓本体Ｖの胴である。操作レバー３は、湯水の混合比の調節機能および止水を含む吐水量の調節機能を有する。４は、ボルトで、胴１から下方へ垂設されている。５は、例えば台所の流し台の水栓取付板部（（以下、単に面板という）である。この面板５には、胴１に連結される給水管６および給湯管７とボルト４とが挿通可能な一つの貫通孔８が開設されている。９は、ナットで、ボルト４の外周面Ｐへ螺着されて胴１を面板５の上面Ｌへ固定設置するためのものである。また、１０は、取付金具（例えば特願平７−２６９４８６号の明細書、図面参照）で、ボルト４が挿通可能で、かつ遊嵌可能な大きさの挿通孔１２を有する一方、給水管６および給湯管７の挿貫部（図示せず）を有する。前記給湯管７は、胴１内に設けた湯流入孔１３に接続されている。また、前記給水管６は、胴１内に設けた水流入孔１４に接続されている。１５は、胴１の下部を覆う下カバー体、１６は、胴１の上部で湯流入孔１３および水流入孔１４の下流に設置される弁機構部３２を覆う上カバー体である。
【０００８】
前記下カバー体１５は、吐水管２直下に膨出部２１を有する。この膨出部２１は、逆止弁コア２２を内嵌したニップル２３を一端に有し、このニップル２３の一端外周面に形成された雄ねじ２４に螺着された環状接続部材２５を介して食器洗い乾燥機２０の給湯ホース２０ａに連結される連接ユニオン２６がニップル２３の一端に装着されている。２９は、連接ユニオン２６の先端に設けた整流器である。前記ニップル２３の貫通穴は、逆止弁コア２２取付用の大径穴２３ａと、後述する熱水防止弁３１が装着される小径穴２３ｂとで構成される。そして、胴１、下カバー体１５および上カバー体１６から混合栓本体Ｖが構成されている。また、この混合栓本体Ｖ、操作レバー３、吐水管２、後述する湯分岐バルブ３０および後述する熱水防止弁３１でワンホール型湯分岐混合栓が構成される。
【０００９】
混合栓本体Ｖの取付けは以下の通りである。まず、面板５の下面Ｎ側の貫通孔８に対応する位置に取付金具１０を位置させながら、ボルト４を取付金具１０の挿通孔１２を介して貫通孔８に挿通させるとともに、給水管６および給湯管７を取付金具１０の前記挿貫部を介して貫通孔８に挿通させる。次に、ナット９およびボルト４の締結操作により面板５の下面Ｎを取付金具１０が押圧する形となり混合栓本体Ｖが面板５の上面Ｌに固定設置される。
【００１０】
１７は、ガス湯沸器等の給湯器で、温度調整機能を有し、給水配管１８の給水流路Ａから分岐した分岐管１９によって形成される入口流路Ｂに連通しており、温度調整された湯が給湯管７によって形成された出口流路である湯導入流路Ｃを介して胴１内に設けた湯流入孔１３に導入される。符号Ｄは、給水配管１８に接続された給水管６によって形成され、胴１内に設けた水流入孔１４に連通する水導入流路である。
【００１１】
以下、この発明の特徴的構成について説明する。
３０は、湯分岐バルブで、湯導入流路Ｃを通り胴１内に設けた湯流入孔１３に導入された湯の一部を逆止弁コア２２側に分岐するためのものである。すなわち、符号Ｅで示す矢印は、ニップル２３の貫通穴２３ａ，２３ｂから連接ユニオン２６の整流器２９に設けた貫通穴２９ａに至る湯分岐流路で、給湯ホース２０ａを介して直接食器洗い乾燥機２０の湯入口２０ｂに連通しており、湯分岐バルブ３０を開くと、湯流入孔１３から給湯器１７で温度調整された湯が、湯分岐流路Ｅから給湯ホース２０ａを通り食器洗い乾燥機２０内に至る。この場合、操作レバー３の止水状態あるいは吐水状態にかかわらず湯分岐バルブ３０を開くことで食器洗い乾燥機２０へ給湯できる。
【００１２】
図４において、栓棒５０の下部にはセラミック製の弁体５２が取り付けられている。この弁体５２は、セラミック製の固定弁体（固定ディスク）５３と、セラミック製の可動弁体（可動ディスク）５４とで構成される。そして、固定ディスク５３には、平面視扇型の弁孔４８が左右対称位置に穿設形成されている。一方、固定ディスク５３の摺動面に密接した状態で可動ディスク５４が栓棒５０の回転軸のまわりに回転自在（例えば１８０°）に配置されている。可動ディスク５４の裏面は、固定ディスク５３の弁孔４８を閉鎖できる形状であるとともに、切欠４９が設けられている。図５は、湯分岐バルブ３０の操作ハンドル３０ａを開にして湯分岐バルブ３０を開いた場合の固定ディスク５３と可動ディスク５４の位置関係を示し、図６は、操作ハンドル３０ａを閉にして湯分岐バルブ３０を閉じた場合の固定ディスク５３と可動ディスク５４の位置関係を示す。
【００１３】
３１は、熱水防止弁で、ニップル２３の小径穴２３ｂに例えばねじ止めにより装着されている。この熱水防止弁３１は、筒状のケース３４と、ケース３４内に前後の仕切壁３５，３６によって仕切られた弁体室３７と、弁体３３と、弁体３３を後仕切壁３６の外周面に沿って形成された複数の連通孔４０の方向へ付勢する付勢ばね４１と、前仕切壁３５の中央に形成された、大径穴２３ａとの連通孔３８の方向へ弁体３３を付勢する形状記憶合金ばね３９とよりなる。
【００１４】
更に、前記弁体３３は棒状であり、先端が先細りのテーパ形状をなすテーパ部３３ａを有する一方、後端は湯の流通を妨げないように複数の切欠ｍを介して放射状に形成された羽根形状の外周部３３ｂを有する。
【００１５】
前記形状記憶合金ばね３９は、所定の温度、例えば、食器洗い乾燥機２０において洗いやすすぎに使用する湯の最高温度である７０℃よりも高くなると、形状復帰して拡張するように形状記憶処理されている。そして、７０℃以下の湯が湯分岐流路Ｅを流れているときは、付勢ばね４１の方が形状記憶合金ばね３９よりも強いばね力を有する一方、７０℃よりも高い湯（熱水）が流れ始めて形状記憶合金ばね３９が形状復帰するときには、形状記憶合金ばね３９の方が付勢ばね４１よりも強いばね力を有するように構成され、この場合、弁体３３のテーパ部３３ａによって前仕切壁３５の連通孔３８が閉塞され、７０℃よりも高い湯（熱水）が食器洗い乾燥機２０に流出するのを防止できる。
【００１６】
なお、７０℃よりも高い湯（熱水）が湯分岐流路Ｅを流れ始めるのは、給湯器１７がその温度に調整されていたからであって、食器洗い乾燥機２０への給湯が停止した時点で給湯停止を知らせるブサー等の警報を発するように構成すれば、食器洗い乾燥機２０の使用者が給湯停止を感知するとともに、７０℃以下の温度に温度調整できる。
【００１７】
また、給湯器１７として例えばガス湯沸器を使用した場合、タイプによっては、７０℃以下に温度調整しても出始めの数秒間は７０℃よりも高い湯が流出する場合があるが、この場合でもこの発明の熱水防止弁３１によって７０℃よりも高い湯（熱水）が食器洗い乾燥機２０に流出するのを防止できる。
【００１８】
【発明の効果】
以上説明したようにこの発明では、以下の効果を有する。
（１）高価なサーモバルブ（ミキシングバルブ）を使用しないので経済的である。
（２）熱水防止弁はサーモバルブ（ミキシングバルブ）のような複雑な構造ではなく簡単な構造を有するので、故障の起きる回数を低くできる。
（３）７０℃よりも高い湯（熱水）が湯分岐流路を流れ始めても、熱水防止弁によって食器洗い乾燥機に流出するのを確実に防止できる。
