Description

【0001】
【発明の属する技術分野】
本発明は、例えばシステムバスルーム等の浴室内のバスタブに設置されるジェットバスの配管構造に関する。
【0002】
【従来の技術】
従来、システムバスルーム等の浴室1のジェットバス2においては、図7に示すように、バスタブ3に固定的に設けた吸込口4と吐水口5a、5bとの間にポンプ6が設けられている。このポンプ6は、吸込口4と吸込側配管7で接続される共に、バスタブ3の背側の壁面3bに設けられた前記吐水口5a、5bあるいはバスタブ3の足側の壁面に設けられた図示しない2個の吐水口とがポンプ吐水側配管8〜10等で接続されている。そしてこの場合、ポンプ6の設置においては、図8に示すように、吸込口4と吐水口5a、5b等との高さ位置関係において、吐水口5a、5b等(H1)>ポンプ6(H3)>吸込口4(H2)となり、かつポンプ吸込側配管7(内部の吸込流路A)がポンプ6側からみて下り勾配で、ポンプ吐水側配管8(内部の吐水流路B)が上り勾配となるように設定する必要がある。
【0003】
そのため、シェットバス2の施工時に、ポンプ6をその取付板11のアジャスター12によって防水パン13の床面13aからの高さを調整することで、ポンプ6を前述した所定高さ位置に設定して設置している。これにより、湯張り時にはポンプ6の作動でポンプ吸込側配管7やポンプ6内の空気がポンプ吐水側配管8〜10を通って吐水口5a、5b等からバスタブ3内に抜けてポンプ6内に吸込口4から水が吸込まれ、また、排水時にはポンプ6内の水が下り勾配のポンプ吸込側配管7を流れて吸込口4からバスタブ3内に排出され、これがバスタブ3の排水孔14(図1参照)から浴室1外に排水されるようになっている。(なお、このようなジェットバス1の配管構造としては、例えば特許文献1に開示されている。)
【0004】
【特許文献1】
特開平8−164081号公報
【0005】
【発明が解決しようとする課題】
しかしながら、このように配管構造のジェットバス2にあっては、施工時のバスタブ3の上縁と洗い場カウンターの面合せあるいはバスタブ3とバスタブエプロンの位置合わせ、防水パン13自体の変形や撓み等のために、防水パン13の床面13aからの高さをスペーサ等によって調整する必要があるため、バスタブ3とポンプ6との高さ位置関係、すなわちバスタブ3に固定的に設けられた吸込口4及び吐水口5a、5b等とポンプ6との高さ位置関係がずれる場合がある。
【0006】
そこで、この高さ位置関係のずれを前記アジャスター12で調整することも考えられるが、ポンプ6の設置スペースであるバスタブ3の背側の壁面3b外側の空間が狭く、アジャスター12まで作業者の手が届かない場合があって、極めて作業性が悪く、ポンプ6を所定の高さ位置に設定することが現実的に困難となる。その結果、ポンプ吸込側配管7とポンプ吐水側配管8の勾配が変化して前述した所定の勾配が得られず、例えばポンプ吸込側配管7が上り勾配となり、排水時にポンプ吸込側配管7内に水が残る場合があったり、あるいはポンプ吐水側配管8が下り勾配となり、ポンプ6が吸込不良で空運転になる場合があるという問題点を有している。
【0007】
本発明は、このような事情に鑑みてなされたもので、その目的は、簡易な構成によりポンプ吸込側配管とポンプ吐水側配管の勾配を所定に設定できて、排水時の配管内への残水等を確実に防止し得るジェットバスの配管構造を提供することにある。
【0008】
【課題を解決するための手段】
かかる目的を達成すべく、本発明のうち請求項1に記載の発明は、バスタブの壁面に設けた吸込口からバスタブ内の水をポンプ吸込側配管を介してポンプに吸込み、該水をポンプ吐水側配管を介して前記壁面に設けた吐水口からバスタブ内に吐水させるジェットバスの配管構造であって、前記ポンプ吸込側配管とポンプ吐水側配管とを連結手段で一体化することにより、ポンプ吐水側配管の吐水流路を水平状態に設定した際に、ポンプ吸込側配管の吸込流路が水平状態もしくは前記吸込口に向けて下り勾配になる如く設定したことを特徴とする。
【0009】
このように構成することにより、ポンプが作動するとバスタブ内の水が吸込口からポンプ吸込側配管を介してポンプ内に吸込まれ、この水がポンプからポンプ吐水側配管及び吐水口を介してバスタブ内に吐水される。この時、ポンプ吸込側配管とポンプ吐水側配管とが連結手段で一体化されて、ポンプ吐水側配管の吐水流路を水平状態に設定した際に、ポンプ吸込側配管の吸込流路が水平状態あるいは吸込口に向けて下り勾配に自動的に設定されることから、施工時にポンプ吸込側配管の吸込流路を所定の下り勾配等に容易に設定することができて、排水時のポンプ吸込側配管内に水が残ること等が確実に防止される。
【0010】
そして、前記連結手段は、請求項2に記載の発明のように、ポンプ吸込側配管とポンプ吐水側配管とに一体成形された連結板で形成されていることが好ましい。このように構成することにより、連結手段が例えば樹脂によってポンプ吸込側配管とポンプ吐水側配管に一体成形された連結板で形成されることから、配管接続部の箇所を削減できて、配管構造を簡略化できる。
【0011】
また、連結手段は、請求項3に記載の発明のように、上部がポンプ吐水側配管に固定された連結板と、該連結板の下部に着脱可能に設けられポンプ吸込側配管を固定する固定部材と、を有することが好ましい。このように構成することにより、ポンプ吸込側配管が連結板の下部に着脱可能な固定部材によって固定されることから、ポンプ吸込側配管の取り外しや該配管の若干の角度調整等が可能となり、ポンプ吸込側配管の設置や該配管へのポンプの接続が容易に行える。
【0012】
また、前記ポンプ吐水側配管は、請求項4に記載の発明のように、バスタブの壁面に設けられた複数の吐水口に対応する複数の吐水口部を有することが好ましい。このように構成することにより、ポンプ吸込側配管の複数の吐水口部がバスタブの壁面に設けられた複数の吐水口にそれぞれ対応していることから、ポンプ吸込側配管の吐水口部をバスタブの複数の吐水口に確実に接続できると共に、ポンプ吸込側配管を所定の勾配に容易に設定できる。
【0013】
【発明の実施の形態】
以下、本発明の実施の形態を図面に基づいて詳細に説明する。
図1〜図4は、本発明に係わるジェットバスの配管構造の一実施形態を示し、図1が該ジェットバスが設置される浴室の平面図、図2がその配管部分を示す正面図、図3がその一部を断面にした側面図、図4がポンプ吸込側配管及びポンプ吐水側配管と連結板を示す正面図である。なお、以下の説明において、図7及び図8に示す部位と同一部位には、同一符号を付して説明する。
【0014】
図1において、浴室1は、例えば平面視方形状の防水パン13の周囲に配置された壁パネル15a〜15d及び図示しない天井パネルによって略箱状に形成され、防水パン13の壁パネル15b側にはバスタブ3が設置され、バスタブ3側方の防水パン13上には一端部にカウンター16が設置された洗い場17が形成されている。
【0015】
前記バスタブ3は、排水孔14を有する底面3aと背側及び足側の壁面3b、3dと側方の壁面3c、3eによって形成され、背側の壁面3bに2個の吐水口5a、5bが設けられ足側の壁面3dに2個の吐水口5c、5dが設けられると共に、側方の壁面3cには吸込口4が設けられている。また、バスタブ3の壁面3b〜3dと壁パネル15a〜15cとの間に形成される空間18内には、ジェットバス2を構成するポンプ6及びこのポンプ6と吸込口4や吐水口5a〜5dとを連結するポンプ吸込側配管7やポンプ吐水側配管8〜10等が配置されている。
【0016】
すなわち、図2及び図3に示すように、吸込口4とポンプ6のポンプ吸込口6aとがポンプ吸込側配管7で接続され、2個の吐水口5a、5bとポンプ吐水口6bとが2個の吐水口部8a、8bを有するポンプ吐水側配管8で接続されている。このポンプ吸込側配管7とポンプ吐水側配管8は、例えば樹脂により形成されてバスタブ3の壁面3b外側に位置し、その長手方向の略中央部分が各配管7、8にブロー成形等で一体成形された連結手段としての連結板19で上下方向に連結されて一体化されている。
【0017】
この時、ポンプ吸込側配管7とポンプ吐水側配管8及び連結板19は、図4に示すように、上方に位置するポンプ吐水側配管8と下方に位置するポンプ吸込側配管7とが互いに角度を有することで不平行となるように連結されている。これにより、ポンプ吐水側配管8(内部の吐水流路B)を水平状態に設定した場合、すなわちポンプ吐水側配管8の2個の吐水口部8a、8bの上端を水平線状に設定した場合に、ポンプ吸込側配管7(内部の吸込流路A)の吸込口4側である一端部7aが下方に位置しポンプ6側である他端部7bが上方に位置するように下り勾配となる如く設定されている。
【0018】
また、このポンプ吸込側配管7とポンプ吐水側配管8の連結板19を介した所定角度を持った連結により、ポンプ吐水側配管8の2個の吐水口部8a、8bと、ポンプ吐水側配管8の両端部8c、8d間及びポンプ吸込側配管7の両端部7a、7b間の高さ寸法h1〜h3が一義的に決定される。これにより、ポンプ6と吸込口4及び吐水口5a、5bの高さ位置関係が吐水口5a、5b>ポンプ6>吸込口4となり、ジェットバス2の施工状態において、ポンプ吐水配管8の吐水流路Bが水平状態(もしくは上り勾配)で、ポンプ吸込側配管7の吸込流路Bが下り勾配に確実に設定されることになる。
【0019】
そして、このように構成されたポンプ吸込側配管7とポンプ吐水側配管8は、図2及び図3に示すように、その両端部が袋ナットやゴム継手等の継手20等を介して吸込口4や吐水口5a、5bあるいはポンプ6等に接続されている。また、他端部8dがポンプ吐水口5bに継手20を介して接続されるポンプ吐水側配管8の反ポンプ6側の一端部8cには、継手20を介してその他端部がバスタブ3の壁面3dの吐水口5c、5dに接続された前記ポンプ吐水側配管10(図7参照)の一端部が接続されている。
【0020】
なお、前記ポンプ吐水側配管8の2個の吐水口部8a、8b間の寸法は、バスタブ3の2個の吐水口5a、5b間の寸法と同一となるように設定されている。また、この例では、ポンプ吸込側配管7とポンプ吐水側配管8を樹脂管で形成することにより、この両配管7、8に連結板19を一体成形したが、両配管7、8として金属管が使用される場合は、金属製の連結板19がその上端部を各配管7、8の外周面に溶接すること等によって一体化される。
【0021】
このように連結板19で一体化されたポンプ吸込側配管7とポンプ吐水側配管8は、ポンプ6以外の部品が工場内においてバスタブ3に取り付けられ、水漏れ検査等が行われた後にポンプ6と共に施工現場に搬入される。そして、施工現場において、バスタブ3に取り付けられているポンプ吐水側配管8の他端部8dに継手20を介してポンプ6のポンプ吐水口6bが接続されると共に、ポンプ吸込側配管7の他端部7bに継手20を介してポンプ6のポンプ吸込口6aが接続される。
【0022】
このポンプ6と各配管7、8等の接続時に、ポンプ6は、図2に示すように、その取付板11のアジャスター12を予め所定高さ位置に設定することにより、アジャスター12が防水パン13の床面13a上に載置された状態で設置される。この時、ポンプ6の各配管7、8への取付高さとなるポンプ吸込側配管7の他端部7bとポンプ吐水側配管8の他端部8dの位置が一義的に決定されることから、バスタブ3の設置高さを勘案しながら、アジャスター12の位置を予め設定しつつポンプ5等が空間18内に設置されるが、継手20として上下方向に若干変形可能なゴム継手を使用すれば、ポンプ6の設置高さに許容差が得られてその設置が容易に行えることになる。
【0023】
そして、ポンプ6が設置されたら、このポンプ6を図1に示すよう、浴室1の例えば天井パネル上に設けた電源ユニット21に接続し、この電源ユニット21に浴室1の例えば壁パネル15bに配置された操作盤22(リモコン)を接続する。これにより、ジェットバス2の設置が完了する。
【0024】
このジェットバス2によれば、前記操作盤22の所定の操作スイッチが操作されてポンプ6が作動することにより、バスタブ3内の水(湯)が吸込口4、ポンプ吸込側配管7、ポンプ吸込口6aを介してポンプ6内に吸込まれ、これがポンプ吐水口6b、ポンプ吐水側配管8、吐水口5a、5bを介してバスタブ3内に噴射される。このポンプ6の作動時に、ポンプ吐水側配管8の吐水流路Bが水平状態に設定されポンプ吸込側配管7の吸込流路Aが下り勾配に設定されていることから、バスタブ3内に湯張りする場合、ポンプ6内やポンプ吐水側配管8内の空気を吐水口5a、5bからバスタブ3内に確実に排出しつつ、吸込口4からバスタブ3内の水をポンプ6内に吸込むことができ、ポンプ6の空運転が確実に防止される。
【0025】
そして、ポンプ6により吸込んだ水は、ポンプ6の作動制御や背側や足側の吐水口5a〜5dに設けた図示しない噴射ノズルの位置設定により、例えば背側の吐水口5a、5bからバスタブ3内にジェット噴流として噴射されたり、足側の吐水口5c、5dからパルス噴流として噴射され、これらの噴流で入浴者に所定のマッサージ効果が得られることになる。
【0026】
また、ポンプ6を停止させてバスタブ3内の水を排水する場合は、ポンプ吐水側配管8やポンプ吸込側配管7内の水が下り勾配を有するポンプ吸込側配管7を介して吸込口4からバスタブ3内に排出され、これがバスタブ3の排水孔14から外部に排水されることになり、排水時にポンプ吸込側配管7内に水が残ることが確実に防止される。
【0027】
このように、上記実施形態のジェットバス2によれば、ポンプ吸込側配管7とポンプ吐水側配管8が連結板19により両配管7、8が異なる角度となるように一体化されているため、ポンプ吐水側配管8の吐水流路Bを水平状態にしてバスタブ3の吐水口5a、5bに取り付けた際に、ポンプ吸込側配管7の吸込流路Bに確実に下り勾配を持たせることができて、排水時の該配管7内への残水が確実に防止され、次のポンプ6の作動を良好に行うことができたり、残水による雑菌の増殖等を防止することができる。
【0028】
また、ポンプ吐水側配管8のポンプ6より上方に位置する2個の吐水口部8a、8bを、バスタブ3の2個の吐水口5a、5bにそれぞれ対応させて該配管8の吐水流路Bを水平状態に設定してバスタブ3に取り付けているため、各吐水口5a、5bとポンプ吐水側配管8の吐水口部8a、8bの各ピッチが一致して、配管作業が容易に行えると共に、ポンプ吐水側配管8の設置時の下り勾配を確実に防止することができて、該配管8内への空気の残留によるポンプ6の吸込不良や空運転を防止することができる。
【0029】
また、両配管7、8が一体化されて吐水口5a、5bや吸込口4に対する位置が一義的に決定されるため、その高さ位置を常に吸込口4<ポンプ6<吐水口5a、5bに設定することができて、施工現場毎の作業バラツキの発生が抑えられた安定した配管状態が得られる。これらのことから、ジェットバス2を確実に動作させて、安定したジェット噴流やパルス噴流等により、入浴者が良好なマッサージ効果を得ることが可能になる。
【0030】
さらに、ポンプ吸込側配管7とポンプ吐水側配管8が連結板19で一体化されているため、各配管7、8における継手20の数等を削減でき、配管構造が簡略化されて配管作業を容易に行うことができる。特に、両配管7、8と連結板19をブロー成型することにより、配管曲げ部の接合箇所を削減できて、配管作業を一層容易に行うことが可能になる。また、ポンプ6のポンプ吐水口6bとバスタブ3の吐水口5a、5bとがポンプ吐水側配管8のみによって接続されているため、従来のポンプ吐水側配管9を必要とせず、配管構造自体を簡素化することができる。
【0031】
また、ポンプ吸込側配管7とポンプ吐水側配管8が連結板19で一体化されて所定の剛性を確保できるため、これらをポンプ6が小型の場合等にその支持部材として機能させることができて、ポンプ6の取付板11やアジャスター12が不要になる等、ポンプ6の設置構造を簡略化することもできる。その結果、狭い空間18内へのポンプ6の設置作業を容易に行うことができると共に、例えば小型のポンプ6の使用によって、ポンプ6を防水パン13から浮かせた状態でポンプ吐水側配管8等に支持させることができ、防水パン13を介したポンプ6の振動音の発生防止等を図ることができる。
【0032】
図5及び図6は、本発明に係わる配管構造の他の実施形態を示す、要部の正面図及びその一部を断面にした側面図である。なお、上記実施形態と同一部位には、同一符号を付して説明する。この配管構造の特徴は、前記連結板19をポンプ吐水側配管8に一体的に固定し、この連結板19の下部にインシュロック帯やU字金具等の着脱可能な固定部材23によりポンプ吸込側配管7を固定した点にある。この時、固定部材23の幅を所定に設定することで、ポンプ吸込側配管7を完全に所定角度位置に固定することもできるが、下り勾配を維持できる範囲で図5の矢印イ方向に若干傾動するように固定することもできる。
【0033】
この実施形態においても、連結板19と固定部材23からなる連結手段でポンプ吸込側配管7とポンプ吐水側配管8を一体化して、ポンプ吸込側配管7の吸込流路Aを常に下り勾配に設定することができるため、上記実施形態と略同様の作用効果を得ることができる。また、ポンプ吸込側配管7が連結板19に着脱可能な固定部材23で固定されるため、ポンプ吸込側配管7を連結板23から取り外すことができて、配管作業やそのメンテナンス作業を容易に行うことができると共に、ポンプ吸込側配管7を傾動可能に取り付けることで、ポンプ6の設置高さのバラツキあるいはポンプ6の吸込口6aと吐水口6b間の寸法バラツキ等に簡単に対応できて、ポンプ吸込側配管7とポンプ6との接続作業が容易に行えるという作用効果が得られる。
【0034】
なお、上記各実施形態においては、バスタブ3に設けられる吐水口5a〜5dが背側と足側に2個づつ合計4個設けられる場合について説明したが、例えば背側の壁面3bにのみ吐水口を2個設けたり、背側あるいは足側の壁面3b、3cに1個の吐水口を設けることもできるし、吸込口4の位置も側方の壁面3cに限らず、背側の壁面3b下部に設けることもでき、吐水口5a〜5dや吸込口4の個数やその配置位置は、バスタブ3自体や吐水される噴流の形態に応じて適宜の構成を採用することができる。
【0035】
また、上記各実施形態においては、ポンプ吐水側配管8の吐水口部8a、8bを同一長さとすることで設置時のポンプ吐水側配管8の吐水流路Bを水平状態に設定したが、例えば吐水口部8a、8bの長さを調整して吐水流路Bをポンプ6からみて上り勾配を有する構成とすることもでき、この場合も、ポンプ吸込側配管7とポンプ吐水側配管8の連結板19により両配管7、8の角度を所定に設定して、ポンプ吐水側配管7は必ず下り勾配となるように設定する。
【0036】
さらに、上記各実施形態においては、ポンプ吸込側配管7自体が吸込口4に向けて下り勾配となる場合について説明したが、ポンプ吸込側配管7は必ずしも下り勾配のみに限定されるものでもなく、水平状態でも下り勾配と同様の作用効果を奏することができる。またさらに、上記各実施形態において、例えばポンプ吸込側配管7を水平部分と下り勾配部分との組合せで構成したり、あるいは水平状態のポンプ吸込側配管7と吸込口4とを連結する下り勾配の配管をさらに設ける構成とすることもできる。
【0037】
また、上記各実施形態においては、ポンプ6のポンプ吐水口6bとバスタブ3の吐水口5a、5bとをポンプ吐水側配管8のみで接続する場合について説明したが、例えば従来例に示すポンプ吐水側配管9をポンプ吐水側配管8と連結板等で連結することにより、ポンプ吸込側配管7とポンプ吐水側配管8、9とを一体化するようにしても良い。また、上記各実施形態における、ポンプ6の設置位置、配管位置及び連結手段の構成等も一例であって、本発明に係わる各発明の要旨を逸脱しない範囲において適宜に変更することができる。
【0038】
【発明の効果】
以上詳述したように、請求項1に記載の発明によれば、ポンプ吸込側配管とポンプ吐水側配管が連結手段で一体化されて、ポンプ吐水側配管の吐水流路を水平状態にした際に、ポンプ吸込側配管の吸込流路が水平状態かあるいは吸込口に向けて下り勾配に自動的に設定されるため、ポンプ吐水側配管の施工でポンプ吸込側配管の吸込流路を容易に所定の下り勾配等とすることができて、排水時のポンプ吸込側配管内への残水等を確実に防止することができる。
【0039】
また、請求項2に記載の発明によれば、請求項1に記載の発明の効果に加え、連結手段が樹脂等によってポンプ吸込側配管とポンプ吐水側配管に一体成形された連結板で形成されるため、配管接続部の箇所を削減できて、配管構造を簡略化することができる。
【0040】
また、請求項3に記載の発明によれば、請求項1に記載の発明の効果に加え、ポンプ吸込側配管が連結板の下部に着脱可能な固定部材によって固定されるため、ポンプ吸込側配管の取り外しや該配管の若干の角度調整等が可能となって、ポンプ吸込側配管の設置や該配管へのポンプの接続等を容易に行うことができる。
【0041】
また、請求項4に記載の発明によれば、請求項1ないし3に記載の発明の効果に加え、ポンプ吸込側配管の複数の吐水口部がバスタブの壁面に設けられた複数の吐水口にそれぞれ対応しているため、ポンプ吸込側配管の吐水口部をバスタブの複数の吐水口に確実かつ容易に接続できると共に、ポンプ吸込側配管を所定の勾配に容易に設定できる等の効果を奏する。

Therefore, at the time of construction of the shet bath 2, the pump 6 is set to the above-mentioned predetermined height position by adjusting the height of the waterproof pan 13 from the floor surface 13a by the adjuster 12 of the mounting plate 11 thereof. Has been installed. Thereby, at the time of filling with hot water, the air in the pump suction side pipe 7 and the pump 6 by the operation of the pump 6 passes through the pump water discharge side pipes 8 to 10 and flows out of the water discharge ports 5a and 5b into the bathtub 3 and into the pump 6. Water is sucked in from the suction port 4, and at the time of drainage, water in the pump 6 flows through the pump suction side pipe 7 having a downward slope and is discharged from the suction port 4 into the bathtub 3. 1) to drain out of the bathroom 1. (Note that such a piping structure of the jet bath 1 is disclosed in, for example, Patent Document 1.)

[Problems to be solved by the invention]
However, in the jet bath 2 having such a piping structure, the upper edge of the bathtub 3 and the counter of the washing place counter at the time of construction, the positioning of the bathtub 3 and the bathtub apron, the deformation and bending of the waterproof pan 13 itself, etc. Therefore, it is necessary to adjust the height of the waterproof pan 13 from the floor surface 13a by a spacer or the like. Therefore, the height positional relationship between the bathtub 3 and the pump 6, that is, the suction port 4 fixedly provided in the bathtub 3 In addition, the positional relationship between the water outlets 5a and 5b and the pump 6 may be shifted.
[0006]
Therefore, it is conceivable to adjust the displacement of the height positional relationship with the adjuster 12. However, the space outside the wall surface 3 b behind the bathtub 3, which is the installation space for the pump 6, is narrow. In some cases, the workability is extremely poor, and it is practically difficult to set the pump 6 at a predetermined height position. As a result, the gradient between the pump suction side pipe 7 and the pump discharge side pipe 8 changes, and the above-mentioned predetermined slope cannot be obtained. For example, the pump suction side pipe 7 becomes an upward slope, and the pump suction side pipe 7 enters the pump suction side pipe 7 during drainage. There is a problem that water may remain, or the pump discharge side pipe 8 may have a downward slope, and the pump 6 may be idle due to poor suction.
[0007]
The present invention has been made in view of such circumstances, and an object of the present invention is to make it possible to set a predetermined gradient between a pump suction-side pipe and a pump discharge-side pipe by a simple configuration, and to maintain a residual gradient in the pipe at the time of drainage. An object of the present invention is to provide a jet bath piping structure capable of reliably preventing water and the like.
[0008]

When the water discharge flow path of the side pipe is set to a horizontal state, the suction flow path of the pump suction side pipe is set to be in a horizontal state or to have a downward slope toward the suction port.
[0009]
With this configuration, when the pump is operated, water in the bathtub is sucked into the pump from the suction port through the pump suction side pipe, and this water is pumped into the bathtub through the pump discharge side pipe and the water discharge port. It is spouted. At this time, when the pump suction side pipe and the pump water discharge side pipe are integrated by the connecting means, and the water discharge flow path of the pump water discharge side pipe is set to a horizontal state, the suction flow path of the pump suction side pipe is in a horizontal state. Alternatively, since the slope is automatically set to the downward slope toward the suction port, the suction flow path of the pump suction side pipe can be easily set to a predetermined downward slope at the time of construction, and the pump suction side at the time of drainage can be set. It is surely prevented that water remains in the pipe.
[0010]
The connecting means is preferably formed by a connecting plate integrally formed with the pump suction side pipe and the pump discharge side pipe as in the second aspect of the present invention. With this configuration, since the connecting means is formed of a connecting plate integrally formed on the pump suction side pipe and the pump discharge side pipe with, for example, resin, the number of pipe connection portions can be reduced, and the pipe structure can be reduced. Can be simplified.
[0011]
Further, the connecting means has a connecting plate whose upper part is fixed to the pump water discharge side pipe and a fixing means which is detachably provided at a lower part of the connecting plate and fixes the pump suction side pipe. And a member. With this configuration, the pump suction side pipe is fixed to the lower part of the connecting plate by a detachable fixing member, so that the pump suction side pipe can be removed, the angle of the pipe can be slightly adjusted, and the like. Installation of a suction side pipe and connection of a pump to the pipe can be easily performed.
[0012]
Further, it is preferable that the pump water discharge side pipe has a plurality of water discharge ports corresponding to a plurality of water discharge ports provided on the wall surface of the bathtub, as in the invention according to claim 4. With this configuration, since the plurality of water outlets of the pump suction side pipe correspond to the plurality of water outlets provided on the wall surface of the bathtub, respectively, the water outlet of the pump suction side pipe is connected to the bathtub. In addition to being reliably connected to a plurality of water outlets, the pump suction side pipe can be easily set to a predetermined gradient.
[0013]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
1 to 4 show an embodiment of a jet bath piping structure according to the present invention. FIG. 1 is a plan view of a bathroom in which the jet bath is installed, and FIG. 2 is a front view showing the piping portion. 3 is a side view in which a part thereof is sectioned, and FIG. 4 is a front view showing a pump suction side pipe, a pump discharge side pipe, and a connecting plate. In the following description, the same parts as those shown in FIGS. 7 and 8 are denoted by the same reference numerals.
[0014]
In FIG. 1, the bathroom 1 is formed in a substantially box shape by wall panels 15 a to 15 d and a ceiling panel (not shown) arranged around a waterproof pan 13 having a rectangular shape in a plan view, for example. The bathtub 3 is installed, and a washing place 17 in which a counter 16 is installed at one end is formed on the waterproof pan 13 on the side of the bathtub 3.
[0015]
The bathtub 3 is formed by a bottom surface 3a having a drain hole 14, back and foot side walls 3b, 3d and side walls 3c, 3e, and two water outlets 5a, 5b are formed on the back side wall 3b. Two water outlets 5c and 5d are provided on the wall surface 3d on the foot side, and a suction port 4 is provided on the side wall surface 3c. In a space 18 formed between the wall surfaces 3b to 3d of the bathtub 3 and the wall panels 15a to 15c, a pump 6 constituting the jet bath 2 and the pump 6, the suction port 4, and the water discharge ports 5a to 5d are provided. The pump suction side pipe 7 and the pump water discharge side pipes 8 to 10 are connected to each other.
[0016]
That is, as shown in FIGS. 2 and 3, the suction port 4 and the pump suction port 6a of the pump 6 are connected by the pump suction pipe 7, and the two water discharge ports 5a and 5b and the pump water discharge port 6b are connected to each other. It is connected by a pump water discharge side pipe 8 having water discharge ports 8a and 8b. The pump suction side pipe 7 and the pump water discharge side pipe 8 are formed of, for example, resin and are located outside the wall surface 3b of the bathtub 3, and a substantially central portion in the longitudinal direction is integrally formed with each of the pipes 7, 8 by blow molding or the like. The connecting plate 19 as a connecting means is connected in the vertical direction and integrated.
[0017]
At this time, as shown in FIG. 4, the pump suction side pipe 7, the pump discharge side pipe 8, and the connecting plate 19 are formed such that the upper pump discharge side pipe 8 and the lower pump suction side pipe 7 have an angle with each other. Are connected so as to be non-parallel. Thereby, when the pump water discharge side pipe 8 (internal water discharge passage B) is set to a horizontal state, that is, when the upper ends of the two water discharge ports 8a and 8b of the pump water discharge side pipe 8 are set to a horizontal line. The pump suction side pipe 7 (internal suction passage A) has a downward slope such that one end 7a on the suction port 4 side is located below and the other end 7b on the pump 6 side is located upward. Is set.
[0018]
Further, by connecting the pump suction side pipe 7 and the pump water discharge side pipe 8 at a predetermined angle via a connection plate 19, the two water discharge ports 8a and 8b of the pump discharge side pipe 8 and the pump water discharge side pipe 8 are connected. The heights h1 to h3 between both ends 8c and 8d of the pump 8 and between both ends 7a and 7b of the pump suction side pipe 7 are uniquely determined. As a result, the height relationship between the pump 6, the suction port 4, and the water discharge ports 5a, 5b becomes the water discharge ports 5a, 5b> the pump 6> the suction port 4, and the water discharge flow of the pump water discharge pipe 8 in the construction state of the jet bath 2. When the path B is in a horizontal state (or an upward slope), the suction flow path B of the pump suction side pipe 7 is surely set to a downward slope.
[0019]
As shown in FIGS. 2 and 3, the pump suction-side pipe 7 and the pump water-discharge side pipe 8 having the above-described configuration have suction ports at both ends thereof through joints 20 such as cap nuts and rubber joints. 4 and water outlets 5a and 5b or a pump 6 or the like. In addition, one end 8c of the pump discharge side pipe 8 on the side opposite to the pump 6 of the pump discharge side pipe 8 whose other end 8d is connected to the pump discharge port 5b through the joint 20 has the other end connected to the wall surface of the bathtub 3 through the joint 20. One end of the pump water discharge side pipe 10 (see FIG. 7) connected to the 3d water discharge ports 5c and 5d is connected.
[0020]
The size between the two water outlets 8a and 8b of the pump water discharge side pipe 8 is set to be the same as the size between the two water outlets 5a and 5b of the bathtub 3. Further, in this example, the pump suction side pipe 7 and the pump water discharge side pipe 8 are formed of resin pipes, and the connection plates 19 are integrally formed on the pipes 7 and 8. Is used, the metal connecting plate 19 is integrated by welding the upper end to the outer peripheral surface of each of the pipes 7 and 8.
[0021]
The pump suction side pipe 7 and the pump discharge side pipe 8 integrated by the connecting plate 19 as described above are mounted on the bathtub 3 in the factory except for the pump 6, and after the water leakage inspection and the like are performed, the pump 6 Together with the construction site. Then, at the construction site, the pump water discharge port 6b of the pump 6 is connected to the other end 8d of the pump water discharge side pipe 8 attached to the bathtub 3 via the joint 20, and the other end of the pump suction side pipe 7 is connected. The pump suction port 6a of the pump 6 is connected to the portion 7b via the joint 20.
[0022]
When the pump 6 is connected to each of the pipes 7, 8 and the like, the adjuster 12 of the mounting plate 11 is set to a predetermined height position in advance as shown in FIG. It is installed in a state where it is placed on the floor surface 13a. At this time, since the positions of the other end 7b of the pump suction side pipe 7 and the other end 8d of the pump water discharge side pipe 8, which are the mounting height of the pump 6 to the pipes 7, 8, are uniquely determined. The pump 5 and the like are installed in the space 18 while setting the position of the adjuster 12 in advance while taking into account the installation height of the bathtub 3, but if a rubber joint that can be slightly deformed in the vertical direction is used as the joint 20, A tolerance is obtained in the installation height of the pump 6, and the installation can be easily performed.
[0023]
When the pump 6 is installed, the pump 6 is connected to a power supply unit 21 provided on, for example, a ceiling panel of the bathroom 1 as shown in FIG. Connected operation panel 22 (remote control). Thus, the installation of the jet bath 2 is completed.
[0024]
According to the jet bath 2, when a predetermined operation switch of the operation panel 22 is operated and the pump 6 is operated, water (hot water) in the bathtub 3 is supplied to the suction port 4, the pump suction side pipe 7, the pump suction side. The liquid is sucked into the pump 6 through the port 6a, and is injected into the bathtub 3 through the pump discharge port 6b, the pump discharge side pipe 8, and the discharge ports 5a and 5b. When the pump 6 is operated, the water discharge passage B of the pump discharge side pipe 8 is set to a horizontal state, and the suction flow path A of the pump suction side pipe 7 is set to a downward slope. In this case, the water in the bathtub 3 can be sucked into the pump 6 from the suction port 4 while reliably discharging the air in the pump 6 and the pump discharge pipe 8 from the discharge ports 5 a and 5 b into the bathtub 3. In addition, the idle operation of the pump 6 is reliably prevented.
[0025]
The water sucked in by the pump 6 is supplied to the bathtub from the backside water outlets 5a, 5b, for example, by controlling the operation of the pump 6 and setting the positions of the injection nozzles (not shown) provided in the backside and foot side water outlets 5a to 5d. 3 is jetted as a jet jet, or jetted as a pulse jet from the water outlets 5c and 5d on the foot side, and these jets can provide a bather with a predetermined massage effect.
[0026]
When the pump 6 is stopped to drain the water in the bathtub 3, the water in the pump discharge pipe 8 and the pump suction pipe 7 is discharged from the suction port 4 through the pump suction pipe 7 having a downward slope. The water is discharged into the bathtub 3 and discharged to the outside through the drain hole 14 of the bathtub 3, so that it is possible to reliably prevent water from remaining in the pump suction side pipe 7 at the time of drainage.
[0027]
As described above, according to the jet bath 2 of the above embodiment, the pump suction side pipe 7 and the pump water discharge side pipe 8 are integrated by the connecting plate 19 such that the pipes 7 and 8 have different angles. When the water discharge flow path B of the pump water discharge side pipe 8 is set in a horizontal state and attached to the water discharge ports 5a, 5b of the bathtub 3, the suction flow path B of the pump suction side pipe 7 can have a downward slope reliably. As a result, the residual water in the pipe 7 at the time of drainage can be reliably prevented, the operation of the next pump 6 can be favorably performed, and the growth of various bacteria due to the residual water can be prevented.
[0028]
Further, the two water outlets 8a and 8b located above the pump 6 of the pump water discharge side pipe 8 correspond to the two water outlets 5a and 5b of the bathtub 3, respectively, so that the water discharge passage B of the pipe 8 is provided. Is set in a horizontal state and attached to the bathtub 3, the respective pitches of the water outlets 5a and 5b and the water outlets 8a and 8b of the pump water discharge side pipe 8 match, and the piping work can be easily performed. It is possible to reliably prevent a downward slope at the time of installation of the pump water discharge side pipe 8, and it is possible to prevent poor suction of the pump 6 and idle operation due to residual air in the pipe 8.
[0029]
Further, since the two pipes 7 and 8 are integrated and the position with respect to the water discharge ports 5a and 5b and the suction port 4 is uniquely determined, the height position is always set to the suction port 4 <the pump 6 <the water discharge ports 5a and 5b. , And a stable piping state in which the occurrence of work variation at each construction site is suppressed can be obtained. From these facts, it becomes possible for the bather to reliably operate the jet bath 2 and obtain a good massage effect by the bather by a stable jet jet or pulse jet.
[0030]
Further, since the pump suction side pipe 7 and the pump discharge side pipe 8 are integrated by the connecting plate 19, the number of the joints 20 in each of the pipes 7 and 8 can be reduced, and the piping structure is simplified and the piping work is simplified. It can be done easily. In particular, by blow-molding the two pipes 7 and 8 and the connecting plate 19, the joints of the pipe bent portions can be reduced, and the pipe work can be performed more easily. Further, since the pump water outlet 6b of the pump 6 and the water outlets 5a, 5b of the bathtub 3 are connected only by the pump water discharge side pipe 8, the conventional pump water discharge side pipe 9 is not required, and the pipe structure itself is simplified. Can be
[0031]
Further, since the pump suction side pipe 7 and the pump water discharge side pipe 8 are integrated by the connecting plate 19 and a predetermined rigidity can be secured, these can be made to function as supporting members when the pump 6 is small. In addition, the mounting structure of the pump 6 can be simplified, for example, the mounting plate 11 and the adjuster 12 of the pump 6 become unnecessary. As a result, the installation work of the pump 6 in the narrow space 18 can be easily performed, and the pump 6 is floated from the waterproof pan 13 to the pump water discharge side pipe 8 or the like, for example, by using the small pump 6. The pump 6 can be supported, and the occurrence of vibration noise of the pump 6 via the waterproof pan 13 can be prevented.
