Description

【０００１】
【発明の属する技術分野】
本発明は、災害時あるいは渇水時でも給水可能な非需用給水装置に関する。
【０００２】
【従来の技術】
従来、災害時あるいは渇水時における生活用水または飲料水の確保手段としては、家庭用ポリタンクに水道水を貯めたり、あるいはペットボトルに入った飲料水を購入することで行っていた。
【０００３】
【発明が解決しようとする課題】
しかしながら、上記した前者の従来技術のように、家庭用ポリタンクに水道水を貯める手段にあっては、その作業が面倒であり、保管場所にもかなりのスペースを有し、また後者のように、ペットボトルに入った飲料水を購入して貯蔵したとしても、長期間となると水質が変化するため、逐次取替えなければならなかった。
【０００４】
そこで水道水の途中に設置され、常時使用される水によってタンク内の水が循環する非常用タンクが、実開昭５３−４０６７３号等で開示されている。しかし、このシステムはタンクの容量が大きく、地中に埋設しなければならないため、設置工事が大変なものがある。また、非常時に水を汲み上げるために、ポンプ等をを利用しなけらばならず、故障率が高いばかりか、電源の確保も考えなければならなかった。
【０００５】
さらに、実公昭５１−３９２１２号には蛇口の側部に設置される循環式のタンクが開示されているが、やはり設置場所としてのスペースを取ってしまう。
【０００６】
さらに、これら従来技術に共通した問題点としては、水道使用時、常時水道水がタンク内に流れ込み、水の流動はあるものの、タンクの径が大きいため死水域が発生し易く、流動を与えられない水がタンク内に残存してしまい非常用に供給される水の水質に問題があった。
【０００７】
本発明は、上記問題点を解決するためになされたもので、極めて薄型でスペースをとらず、非常時にはこれらの薄型の貯水部から水を容易に取り出すことのできる非常用給水装置を提供することを目的としている。
【０００８】
【課題を解決するための手段】
本発明の非常用給水装置は、一端部に導入口を、そして他端部に排水口を有する管状部材を横方向に複数本ほぼ隣接させ、前記単一の管状部材の導入口と他の管状部材の排水口とを順次連通部で連結して一体化した流動式の貯水流路が形成されており、前記単一の管状部材の導入口と他の管状部材の排水口との連通部の位置と相対するそれぞれの管状部材の端部が、前記連通部の流水抵抗よりも大きな通路の連通部で連結されているとともに、少なくとも前記複数の一体化された管状部材の最上部付近に空気弁を設置し、最上部の管状部材の導入口を上水道配管に連通させ、さらに最下部の管状部材の排水口を給水カランに連通させることを特徴としている。
この特徴により、水道水の使用によって順次水が流れ、死水のない状態で、これら管状部材によって構成される貯水流路に水が常時確保されている。非常時には、下方の給水用カランを開くことにより、水圧で常時閉塞している空気弁が開くため、これら管状部材内に蓄えられた水を自然落下により大量に使用できる。特にこの給水装置はそれぞれ別々の細い管状部材の集合体であるため、強度が高く、また水の流れもスムーズとなる。
【０００９】
本発明の非常用給水装置は、連通部で連結される管状部材の排水口が、その管状部材の最下端部近傍に、さらにその下方の管状部材の導入口が、その管状部材の最上端部近傍に形成されていることが好ましい。
【００１０】
本発明の非常用給水装置は、貯水流路を形成する各管状部材を連通する連通部が管状部材の外部に延びる連通管であることが好ましい。
【００１２】
本発明の非常用給水装置は、上下の管状部材を連通させる流水抵抗の大きな連通部が、上方の管状部材の一端の最下端部と下方の管状部材の一端の最上端部とを繋いでいることが好ましい。
【００１３】
本発明の非常用給水装置は、前記流水抵抗の大きな連通部が、管状部材の外部に延びる排水管であることが好ましい。
【００１４】
本発明の非常用給水装置は、前記複数の管状部材は、一方向に傾斜させて設置することが好ましい。
【００１５】
本発明の非常用給水装置は、前記管状部材、該管状部材に設けられた導入口および排水口、最上部に取付けられる空気弁と管状部材とが連通する接続口および管状部材同士を連通する連通部を、凹部を有する２枚の板材を互いに液密に張合わせてパネル状に形成することが好ましい。
【００１６】
本発明の非常用給水装置は、少なくとも前記管状部材と前記空気弁とが基台から上方に延設された堅固なフレームにより外力から保護されていることが好ましい。
【００１８】
【発明の実施の形態】
以下、実施の形態を挙げ図面に基づいて本発明を説明する。
【００１９】
図１は本発明の一実施形態を示す非常用給水装置の全体図である。
【００２０】
図１に示す台所１は、流し台２と、この流し台２の奥面に位置する壁３とで構成され、流し台２にはシンク部４が設けられ、シンク部４の上部には給水カラン５が設けられている。
【００２１】
６は、本発明の実施形態の非常用給水装置であって、この非常用給水装置６は、横方向に設置された複数の管状部材７ａ〜７ｃと、連通部としての連通管８ａ〜８ｄと、全ての管状部材の底部とこの管状部材に隣接する下部管状部材を連通する排水管９ａ、９ｂと、空気弁１０とで構成され、この非常用給水装置６は、壁３内に水平に埋設される。
【００２２】
複数の管状部材７ａ〜７ｃは、内面が防錆処理された金属、プラスチック又はステンレス等で形成され、互いに隣接して接着により接続され一体化されている。なお、一体化とは、それぞれが接着もしくは溶接されていることも含むが、連結管等で接続されていることも一体化の意味である。
【００２３】
管状部材７ａ〜７ｃの両端は閉塞されており、その閉塞された両端には全て導入口１１と排水口１２が形成され、これら導入口１１と排水口１２には各管状部材を結ぶほぼ同じ内径の連通管８ａ〜８ｄで連結されている。
【００２４】
図１に基づいてさらに詳しく説明すると、連通管８ａは、複数の管状部材の内、最上段に位置する管状部材の上端部から水道水を供給するように連結されている。
【００２５】
そして、最上段に位置する管状部材７ａの一端下部と中段の管状部材７ｂの一端上部は太い連通管８ｂで連結され、同様に両管状部材７ａ、７ｂの他端下部と上部は細い連通管としての排水管９ａで連結されている。
【００２６】
また、中段の管状部材７ｂの一端下部と最下段の管状部材７ｃの一端上部は細い排水管９ｂで連結され、同様に管状部材７ｂ、７ｃの他端下部と上部は太い連通管としての連通管８ｃで連結されている。
【００２７】
さらに、最下段の管状部材７ｃの一端下部には連通管８ｄが連結されており、この連通管８ｄは、常時使用される給水カラン５に連結されている。
【００２８】
尚、図示はしないが、給水カラン５とは別に非常用カランを設けて、この非常用カランに管状部材７ｃの他端下部に設けた排水管を連結させるようにしても良い。
【００２９】
ここで重要な点は、連通管８ａ〜８ｄは排水管９ａ、９ｂよりも管の内径が大きくなっており、従って、連通管８ａから給水される水道水は、そのほとんどが各連通管８ｂ〜８ｃを介して隣接する各管状部材７ａ〜７ｃ内を順次左右に流動しつつ排水口１２に流下し、排水口１２に連結されている連通管８ｄを介して給水カラン５から排水される。
【００３０】
即ち、排水管９ａ、９ｂを流れる流水抵抗は、単一の管状部材の排出口と他の管状部材の導入口とを連通する連通部である連通管８ｂ、８ｃの流水抵抗よりも大きくなるように設定されているので、通常、連通管８ａから流入する水は、排水管９ａ、９ｂを介して短絡することなく管状部材７ａ〜７ｃをジグザグに流れ、給水カラン５から排出される。
【００３１】
このように、水道水の使用によって順次水が流れ、死水のない状態で、これら管状部材によって構成される貯水流路に水が常時確保されていることになる。即ち、非常時、例えば時間断水、地震等による水道管破裂時、水圧がなくなり、給水が断たれた場合等にあっても常時貯水流路に水が存在している。
【００３２】
ここで、貯水流路内の水が欲しい場合、単に給水カラン５を開くのみで管状部材内の水をほとんど全て流出させることができる。その理由は、管内に常時かかっている水圧により空気弁１０は閉塞されているが、上流からの水圧が解除されることにより、空気弁１０が大気を貯水流路内に導入すべく自動的に開放される。このため、排水管９ａ、９ｂを介して連通している各管状部材７ａ〜７ｃ内の水道水は、負圧による拘束が解け、水の重量で上から順次流下し排水口１２を介して給水カラン５から流出していく。
【００３３】
ここで、排水管９ａ、９ｂの口径は、単一の管状部材の排出口と、他の管状部材の導入口とを連通する連通部の口径より小径になっており、通常の水の使用時にはこの排水管には水がほどんど流れないが、非常時において管状部材７ａ〜７ｃ等が傾いている場合等にそれぞれの管状部材の他端に水が残留することになるが、この排水管９ａ、９ｂは他端に残留する水を下方の管状部材に流下させる働きをする。ただし、管状部材がほぼ水平に設置され動かないような場合は不要である。
【００３４】
ここで１３は、複数の管状部材７ａ〜７ｃを取付けるための基台であって、この基台１３上に堅固なフレーム１４で箱体が構成されており、その内部空間に複数の管状部材７ａ〜７ｃが図示しない取付具により取付られる。
【００３５】
すなわち、複数の管状部材７ａ〜７ｃおよびこの管状部材に連結される各連通管８ａ〜８ｃ、排水管９ａ、９ｂおよび空気弁１０は、フレーム１４で形成された箱体内に収納されて保護され、これらによって構成される非常用給水装置が、台所等の壁３内に埋め込まれる。
【００３６】
なお、水道水が再度上流から流れ、管状部材内に流入した場合は、最上部に存在する空気弁１０から前述と逆に空気が効率良く排出され、水道使用時のウォーターハンマー等の問題もなくなる。
【００３７】
図２には第２の実施形態が示され、この実施形態は、複数の管状部材１５ａ〜１５ｃを給水カラン側の出口を下に傾斜させて平行に設置したものである。
【００３８】
管状部材１５ａ〜１５ｃの両端は閉塞されており、その閉塞された両端には全て導入口１８と排水口１９が形成され、これら導入口１８と排水口１９には各管状部材を結ぶほぼ同じ内径の連通管１６ａ〜１６ｄが連結されている。
【００３９】
すなわち、複数の管状部材の内、最上段の管状部材１５ａは、その一端下部と中段の管状部材１５ｂの一端上部が太い連通管１６ｂで連結され、同様に上・中段管状部材１５ａ、１５ｂの他端下部と上部は細い排水管１７ａで連結されている。
【００４０】
また中段の管状部材１５ｂは、その一端下部と最下段管状部材１５ｃの一端上部が細い排水管１７ｂで連結され、同様に中・下段管状部材１５ｂ、１５ｃの他端下部と上部は太い連通管１６ｃで連結されている。
【００４１】
さらに、最下段管状部材１５ｃの一端下部には連通管１６ｄが連結されており、この連通管１６ｄは、常時使用される図示しない給水カランに連結されている。そして、管状部材１５の給水側端部の最上部には空気弁１０が設置されている。
【００４２】
このように第２実施形態においても第１実施形態と同様に、排水管を流れる流水抵抗が、単一の管状部材の排出口と、他の管状部材の導入口とを連通する連通部の流水抵抗よりも大きくなるように設定されているので、通常の水の使用時には排水管により水の流れが短絡することがなく、各管状部材の内部は、水道水の使用によって死水のない状態で順次水がジグザグに流れ、これら管状部材によって構成される貯水流路に水が常時確保されている。
【００４３】
また、非常時の場合には、水圧がなくなり、下方の給水カラン５を開くことにより、空気弁１０が自動的に開き、これにより、水道水は自重により順次、連通管１６ｂ、排水管１７ｂを介して流下し、最後の排水口１９に連結されている給水カラン５から全て排出することが可能となる。
【００４４】
本実施形態にあっては、管状部材１５〜１５ｃを給水カラン５に連結される排水口１９の方向に当初から傾斜させて構成しているため、壁内等にこの非常用給水装置を設置する時に、格別水平度を考慮する必要がないばかりか、非常流水後、水道から給水が開始された場合に空気が管状部材の片方上部に集中するため、確実に空気を上方へ送ることができ、空気残留を防止できる。
【００４５】
次に、図３には第３の実施形態が示され、複数の管状部材を箱体内部を隔壁により複数に仕切って構成したものである。
【００４６】
液密に形成された箱体２０は、その内部を複数の隔壁２１ａ、２１ｂで液密に仕切って複数の部屋２２ａ、２２ｂおよび２２ｃを区画している。
【００４７】
各部屋２２ａ〜２２ｃの両端には全て導入口２５、連通穴２３ｂ、２３ｃおよび排水口２６と排水穴２４ａ、２４ｂが形成され、これら導入口と排水口は箱体内部の隔壁に形成された連通穴および排水穴により連通している。
【００４８】
そして、連通管２３ａは、複数の部屋の内、最上部に位置する部屋２２ａの上端から水道水を供給するように連結されている。
【００４９】
ここで、箱体２０の最上段の部屋２２ａと中段の部屋２２ｂとは隔壁２１ａで仕切られており、この隔壁２１ａの連通管２３ａと反対の一端には連通穴２３ｂが形成されている。
【００５０】
この連通穴２３ｂは、前述した実施形態における連通管８ｂ、１６ｂに相当し、また、中段の部屋２２ｂと最下段の部屋２２ｃとを仕切る隔壁２１ｂの連通穴２３ｂの反対の他端にも前述した実施形態における連通管８ｃ、１６ｃに相当する連通穴２３ｃが形成されている。
【００５１】
さらに、隔壁２１ａ、２１ｂにはそれぞれの連通穴２３ｂ、２３ｃと反対端部に排水穴２４ａ、２４ｂが形成されている。この排水穴２４ａ、２４ｂの開口面積は、連通部としての連通穴２３ｂ、２３ｃの開口面積より小さく形成されている。
【００５２】
そして、最下段の部屋２２ｃの一端下部には連通管２３ｄが連結されており、この連通管２３ｄは、常時使用される給水カラン５に連結されている。
【００５３】
尚、箱体２０内を仕切って各部屋を区画する隔壁２１ａ、２１ｂおよび底壁２１ｃは、水平状態に設定した例について述べたが、これを第２の実施形態で述べたように傾斜状態に設定しても良い。なお、水平状態で設置する場合は、排水穴２４ａ、２４ｂは必ずしも必要なものではない。
【００５４】
このように、箱体２０の内部に形成される各部屋２２ａ、２２ｂおよび２２ｃが隔壁２１ａ、２１ｂに形成された連通穴２３ｂ、２３ｃを介して内部で連通されるので、前記実施形態のように、複数の管状部材を隣接して一体化された複数の管状部材の如く、管状部材の外部に連通部および排水管が露出することがなくなり、このための配管が省略できる。
【００５５】
次に、図４には第４の実施形態が示され、この実施形態は、前述した管状部材と、これに連通接続される各部材を、対向する２枚の例えば繊維強化プラスチックから成る板材に対称凹形に成形し、これら板材を互いに液密に張合わせてパネル状に形成したものである。
【００５６】
すなわち、これら２枚の板材３１ａ、３１ｂを互いに張合わせてなるパネル３１には、対向する１組の対称凹部で形成される排水口側を下に傾斜させて複数の管状部材３２ａ〜３２ｃを成形すると共に、最上段の管状部材３２ａに連結されるよう連通管３３ａが成形される。
【００５７】
最上段の管状部材３２ａは、その一端下部と中段の管状部材３２ｂの一端上部が連通管３３ｂで連結され、同様に上・中段管状部材３３ａ、３３ｂの他端下部と上部は排水管３４ａで連結されている。
【００５８】
また中段の管状部材３２ｂは、その一端下部と最下段管状部材３２ｃの一端上部が排水管３４ｂで連結され、同様に中・下段管状部材３２ｂ、３２ｃの他端下部と上部は連通管３３ｃで連結されている。
【００５９】
さらに、最下段管状部材３２ｃの一端下部には連通管３３ｄが連結されており、この連通管３３ｄは、常時使用される図示しない給水カランに連結されている。
【００６０】
そして、最上段の管状部材３２ａの給水側端部の上部には、空気弁を連結するための接続口３５が成形されている。
【００６１】
このように成形された２枚の繊維強化プラスチックからなる板材３１ａ、３１ｂを互いに液密に接合することにより、パネル３１が完成される。
【００６２】
このパネル３１は、図示しない薄形の箱体内に収納設置して、これを例えば台所の壁内に埋設することができる。
【００６３】
またパネル３１が、透明な繊維強化プラスチックで構成されれば、内部の水の残存状態や流れを監視することができる。
【００６４】
このようにパネル３１によって構成された各管状部材の内部は、水道水の使用によって死水のない状態で順次水が流れ、これら管状部材によって構成される貯水流路に水が常時確保される。
【００６５】
また、非常時には、水圧がなくなり、下方の給水カランを開くことにより、空気弁が開き、各管状部材３２ａ〜３２ｃ内の水道水は、連通管３３ｂ、３３ｃ、排水管３４ａ、３４ｂを介して流下し、順次最下段の管状部材３２ｃから排水口３６、連通管３３ｄ、そして給水カランへと流れ、貯留水を全て排出することが可能となる。
【００６６】
以上、本発明の実施形態を図面によって説明してきたが、具体的な構成はこれら実施形態に限られるものではなく、本発明の要旨を逸脱しない範囲における変更や追加があっても本発明に含まれる。
【００６７】
例えば、実施形態では、非常用給水装置を台所に適用した例を示したが、ユニットバス、洗面台等に埋め込んでも良く、壁に対して基台やフレームを利用して固定しても良い。
【００６８】
また、空気弁１０の位置は地震等によって破損しにくい場所であり、かつ残留する空気を全て排出することのできる最上部であれば、管状部材、箱体、パネル、または連通管のいずれに取付けてもよい。
【００６９】
さらに、連通管の内径が排水管の内径よりも大きく形成された実施例を示したが、排水管に所定の抵抗を与えるような構造にしても同じ機能を有する。
【００７０】
また、管状部材等をより多数連結して貯水量を大量に得られることは言うまでもない。
【００７１】
また、連通管、排水管に代えて管状部材と管状部材との当接面に開口を施して水の通過を許す連通部としてもよい。
【００７２】
【発明の効果】
本発明は次の効果を奏する。
【００７３】
（ａ）請求項１によれば、水道水の使用によって順次水が流れ、死水のない状態で、これら管状部材によって構成される貯水流路に水が常時確保されている。非常時には、下方の給水用カランを開くことにより、水圧で常時閉塞している空気弁が開くため、これら管状部材内に蓄えられた水を自然落下により大量に使用できる。特にこの給水装置はそれぞれ別々の細い管状部材の集合体であるため、強度が高く、また水の流れもスムーズとなる。更に、常時は水道水が管状部材の導入口から入った水が管状部材内部を流れ、その端部の排水口から次の管状部材へと流れ、水はジグザクに効率良く流れ、死水が発生しない。これは導入口と排水口とを結ぶ連通部がその反対に位置する流通路よりも流水抵抗が少ないためである。非常時においては、この流水抵抗の大きい連通部が、導入口と排水口とを結ぶ連通路と共働して水を下方に流下させるため、管状部材内の水の残留を極力防止できる。
【００７４】
（ｂ）請求項２によれば、非常時の水の自然落下時において、管状部材の排出口がその管状部材の最下端部に存在するため、水がほどんど全て落下し、水の残留を防止できる。また、非常流水後、これら管状部材に水道の給水が開始された際、内部の空気を残らず上方の空気弁から排出できることになる。
【００７６】
（ｃ）請求項４によれば、この流水抵抗の大きい連通部が請求項２と同様の働きをし、例え管状部材が傾いていたとしても、水の流下を促進するとともに、水道の給水が開始された際、内部の空気を残らず、上方の空気弁から効果的に排出できることになる。
【００７７】
（ｄ）請求項７によれば、大量生産が可能となり、製造原価を低減させることができる。
【００７８】
（ｅ）請求項８によれば、非常用給水管が外部からの力により破壊されることがなく、また、非常用給水管を壁内に埋め込む際にあたっても、空気弁周辺の空間が確保される。

BACKGROUND OF THE INVENTION
The present invention relates to a non-demand water supply apparatus that can supply water even in the event of a disaster or drought.
[0002]
[Prior art]
Conventionally, as a means for securing domestic water or drinking water in the event of a disaster or drought, tap water has been stored in a household plastic tank or drinking water in a plastic bottle has been purchased.
[0003]
[Problems to be solved by the invention]
However, as in the former prior art described above, in the means for storing tap water in a household plastic tank, the work is troublesome, and there is a considerable space in the storage location. Even if you purchase and store drinking water in a plastic bottle, the quality of the water will change over a long period of time, so you have to replace it.
[0004]
Therefore, an emergency tank that is installed in the middle of tap water and in which water in the tank is circulated by water that is always used is disclosed in Japanese Utility Model Publication No. 53-40673. However, this system has a large tank capacity and has to be buried in the ground. In addition, in order to pump up water in an emergency, a pump or the like must be used. In addition to a high failure rate, it was necessary to consider securing a power source.
[0005]
Furthermore, Japanese Utility Model Publication No. 51-39212 discloses a circulating tank installed at the side of the faucet, but it also takes up space as an installation place.
[0006]
Furthermore, a problem common to these prior arts is that, when using tap water, tap water always flows into the tank, and there is water flow, but because the tank diameter is large, a dead water area is likely to be generated and flow is given. There was a problem with the quality of the water supplied for emergency use because no water remained in the tank.
[0007]
The present invention has been made to solve the above problems, and provides an emergency water supply apparatus that is extremely thin and does not take up space, and that can easily take out water from these thin water reservoirs in an emergency. It is an object.
[0008]
[Means for Solving the Problems]
The emergency water supply apparatus according to the present invention includes a plurality of tubular members having an inlet at one end and a drain outlet at the other end, which are substantially adjacent to each other in the lateral direction. A fluid-type water storage channel is formed by sequentially connecting and draining the member drainage ports at the communicating portion, and the communicating portion between the inlet port of the single tubular member and the drainage port of the other tubular member is formed. Ends of the respective tubular members facing the position are connected by a communication portion of a passage larger than the flow resistance of the communication portion, and at least an air valve near the uppermost portion of the plurality of integrated tubular members , And the inlet of the uppermost tubular member communicates with the water supply pipe, and the drainage outlet of the lowermost tubular member communicates with the water supply curan.
Due to this feature, water flows in sequence by the use of tap water, and water is always secured in the water storage channel constituted by these tubular members in a state without dead water. In an emergency, an air valve that is always closed by water pressure is opened by opening the lower water supply curan, so that a large amount of water stored in these tubular members can be used by natural fall. In particular, since this water supply apparatus is an assembly of separate thin tubular members, the strength is high and the flow of water is smooth.
[0009]
In the emergency water supply device of the present invention, the drainage port of the tubular member connected by the communicating portion is in the vicinity of the lowermost end portion of the tubular member, and the inlet port of the lower tubular member is the uppermost end portion of the tubular member. It is preferably formed in the vicinity.
[0010]
In the emergency water supply device of the present invention, it is preferable that the communicating portion that communicates each tubular member that forms the water storage channel is a communicating tube that extends to the outside of the tubular member.
[0012]
In the emergency water supply apparatus of the present invention, the communicating portion having a large flow resistance for communicating the upper and lower tubular members connects the lowermost end portion of one end of the upper tubular member and the uppermost end portion of one end of the lower tubular member. It is preferable.
[0013]
In the emergency water supply device of the present invention, it is preferable that the communicating portion having a large flow resistance is a drain pipe extending to the outside of the tubular member.
[0014]
In the emergency water supply apparatus of the present invention, it is preferable that the plurality of tubular members be installed in a tilted direction.
[0015]
The emergency water supply device of the present invention includes the tubular member, an inlet and a drain provided in the tubular member, a connection port through which an air valve attached to the uppermost portion communicates with the tubular member, and a communication through which the tubular members communicate with each other. It is preferable that the part is formed in a panel shape by liquid-tightly bonding two plate materials having concave parts.
[0016]
In the emergency water supply apparatus of the present invention, it is preferable that at least the tubular member and the air valve are protected from external force by a rigid frame extending upward from the base.

DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, the present invention will be described based on the drawings with embodiments.
[0019]
FIG. 1 is an overall view of an emergency water supply apparatus showing an embodiment of the present invention.
[0020]
The kitchen 1 shown in FIG. 1 is composed of a sink 2 and a wall 3 located at the back of the sink 2, the sink 2 is provided with a sink portion 4, and a water supply currant 5 is provided above the sink portion 4. Is provided.
[0021]
6 is an emergency water supply apparatus according to an embodiment of the present invention. The emergency water supply apparatus 6 includes a plurality of tubular members 7a to 7c installed in a lateral direction, and communication pipes 8a to 8d as communication parts. The drainage pipes 9a and 9b communicate with the bottom of all the tubular members, the lower tubular member adjacent to the tubular member, and the air valve 10. The emergency water supply device 6 is embedded in the wall 3 horizontally. Is done.
[0022]
The plurality of tubular members 7a to 7c are formed of metal, plastic, stainless steel, or the like whose inner surfaces are rust-proofed, and are connected and integrated by adhering to each other. Note that the term “integrated” includes bonding or welding to each other, but connecting with a connecting pipe or the like also means integration.
[0023]
Both ends of the tubular members 7a to 7c are closed, and an introduction port 11 and a drainage port 12 are formed at all the closed ends. The introduction port 11 and the drainage port 12 have substantially the same inner diameter that connects the tubular members. Are connected by communication pipes 8a to 8d.
[0024]
Describing in more detail with reference to FIG. 1, the communication pipe 8 a is connected so as to supply tap water from the upper end portion of the tubular member located at the uppermost stage among the plurality of tubular members.
[0025]
The lower end of the tubular member 7a located at the uppermost stage and the upper end of the middle tubular member 7b are connected by a thick communicating pipe 8b. Similarly, the lower end and the upper end of both tubular members 7a, 7b are formed as thin communicating pipes. Are connected by a drain pipe 9a.
[0026]
The lower end of the middle tubular member 7b and the upper end of the lowermost tubular member 7c are connected by a thin drainage pipe 9b, and the lower end and the upper end of the tubular members 7b and 7c are similarly connected as a thick communication pipe. It is connected by 8c.
[0027]
Further, a communication pipe 8d is connected to a lower end of the lowermost tubular member 7c, and this communication pipe 8d is connected to a water supply currant 5 that is always used.
[0028]
Although not shown, an emergency currant may be provided separately from the water supply currant 5, and a drain pipe provided at the lower end of the other end of the tubular member 7 c may be connected to the emergency curran.
[0029]
The important point here is that the communication pipes 8a to 8d have a larger inner diameter than the drain pipes 9a and 9b. Therefore, most of the tap water supplied from the communication pipe 8a is each of the communication pipes 8b to 8b. While flowing through the tubular members 7 a to 7 c adjacent to each other through 8 c sequentially to the left and right, it flows down to the drain port 12, and is drained from the water supply currant 5 through the communication pipe 8 d connected to the drain port 12.
[0030]
That is, the flowing water resistance flowing through the drain pipes 9a and 9b is larger than the flowing water resistance of the communication pipes 8b and 8c, which are communication parts that connect the discharge port of the single tubular member and the introduction port of the other tubular member. Therefore, the water flowing in from the communication pipe 8 a normally flows through the tubular members 7 a to 7 c through the drain pipes 9 a and 9 b in a zigzag manner and is discharged from the water supply currant 5.
[0031]
In this way, the water flows sequentially by the use of tap water, and water is always secured in the water storage channel constituted by these tubular members in a state where there is no dead water. That is, water is always present in the water storage channel even in an emergency, for example, when the water pipe is ruptured due to time interruption or earthquake, etc., even when the water pressure is lost and the water supply is cut off.
[0032]
Here, when the water in the water storage channel is desired, almost all the water in the tubular member can be discharged by simply opening the water supply currant 5. The reason is that the air valve 10 is closed due to the water pressure constantly applied in the pipe, but the air valve 10 automatically releases the air into the water storage channel by releasing the water pressure from the upstream. Opened. For this reason, the tap water in the tubular members 7a to 7c communicating with each other through the drain pipes 9a and 9b is released from restraint due to the negative pressure, and sequentially flows down from the top by the weight of the water to be supplied through the drain port 12. It flows out from Karan 5.
[0033]
Here, the diameters of the drain pipes 9a and 9b are smaller than the diameter of the communication part that communicates the discharge port of the single tubular member and the introduction port of the other tubular member. Although water hardly flows into this drain pipe, water remains at the other end of each tubular member when the tubular members 7a to 7c and the like are inclined in an emergency, but this drain pipe 9a. 9b serves to cause the water remaining at the other end to flow down to the lower tubular member. However, this is not necessary when the tubular member is installed almost horizontally and does not move.
[0034]
Here, reference numeral 13 denotes a base for mounting the plurality of tubular members 7a to 7c, and a box is formed of a rigid frame 14 on the base 13, and the plurality of tubular members 7a are formed in the internal space. -7c are attached by a fixture (not shown).
[0035]
That is, the plurality of tubular members 7a to 7c and the communication pipes 8a to 8c connected to the tubular members, the drain pipes 9a and 9b, and the air valve 10 are housed and protected in a box formed by the frame 14, An emergency water supply apparatus constituted by these is embedded in a wall 3 such as a kitchen.
[0036]
In addition, when tap water flows again from the upstream and flows into the tubular member, air is efficiently discharged from the air valve 10 existing at the uppermost position, contrary to the above, and there is no problem such as a water hammer when using the tap water. .
[0037]
FIG. 2 shows a second embodiment, in which a plurality of tubular members 15a to 15c are installed in parallel with the outlet on the water supply currant side inclined downward.
[0038]
Both ends of the tubular members 15a to 15c are closed, and an introduction port 18 and a drain port 19 are formed at all the closed ends, and the inlet port 18 and the drain port 19 have substantially the same inner diameter that connects the tubular members. The communication pipes 16a to 16d are connected.
[0039]
That is, among the plurality of tubular members, the uppermost tubular member 15a is connected to the lower end of one end thereof and the upper end of the middle tubular member 15b by the thick communication pipe 16b, and similarly to the upper and middle tubular members 15a and 15b. The lower end and the upper end are connected by a thin drain pipe 17a.
[0040]
The middle tubular member 15b is connected to the lower end of one end thereof and the upper end of the lowermost tubular member 15c by a thin drain pipe 17b. Similarly, the lower end and upper end of the middle and lower tubular members 15b, 15c are thick communication pipes 16c. It is connected with.
[0041]
Further, a communication pipe 16d is connected to a lower end of the lowermost tubular member 15c, and the communication pipe 16d is connected to a water supply curan (not shown) that is always used. And the air valve 10 is installed in the uppermost part of the water supply side edge part of the tubular member 15. FIG.
[0042]
As described above, in the second embodiment, as in the first embodiment, the flowing water resistance flowing through the drain pipe is the flowing water in the communication portion that connects the discharge port of the single tubular member and the introduction port of the other tubular member. Since it is set to be greater than the resistance, the flow of water is not short-circuited by the drain pipe when using normal water, and the inside of each tubular member is sequentially in the state of no dead water due to the use of tap water Water flows zigzag, and water is always secured in the water storage channel constituted by these tubular members.
[0043]
In the case of an emergency, the water pressure disappears, and the air supply valve 10 is automatically opened by opening the lower feed water currant 5, whereby tap water is sequentially connected to the communication pipe 16 b and the drain pipe 17 b by its own weight. It is possible to discharge all from the water supply currant 5 that flows down and is connected to the last drain port 19.
[0044]
In this embodiment, since the tubular members 15 to 15c are inclined from the beginning in the direction of the drain port 19 connected to the water supply currant 5, the emergency water supply device is installed in a wall or the like. Sometimes it is not necessary to consider special levelness, but after emergency water flow, when water supply is started from the water supply, air concentrates on one upper part of the tubular member, so that air can be sent upwards reliably, Air residue can be prevented.
[0045]
Next, FIG. 3 shows a third embodiment, in which a plurality of tubular members are configured by partitioning the inside of a box body into a plurality of partitions.

A communication hole 23c corresponding to the communication pipes 8c and 16c in the embodiment is formed.
[0051]
Further, drainage holes 24a and 24b are formed in the partition walls 21a and 21b at the ends opposite to the respective communication holes 23b and 23c. The opening areas of the drain holes 24a and 24b are formed smaller than the opening areas of the communication holes 23b and 23c as communication parts.
[0052]
A communication pipe 23d is connected to a lower end of the lowermost chamber 22c, and the communication pipe 23d is connected to a water supply currant 5 that is always used.
[0053]
The partition walls 21a and 21b and the bottom wall 21c that partition the inside of the box 20 to divide each room have been described as being in the horizontal state. However, as described in the second embodiment, the partition walls 21a and 21b and the bottom wall 21c are inclined. May be set. In addition, when installing in a horizontal state, the drain holes 24a and 24b are not necessarily required.
[0054]
As described above, the chambers 22a, 22b and 22c formed inside the box body 20 communicate with each other through the communication holes 23b and 23c formed in the partition walls 21a and 21b. As in the case of a plurality of tubular members in which a plurality of tubular members are integrated adjacently, the communication portion and the drain pipe are not exposed to the outside of the tubular member, and piping for this purpose can be omitted.
[0055]
Next, FIG. 4 shows a fourth embodiment. In this embodiment, the above-described tubular member and each member connected in communication with the above-described tubular member are formed into two opposing plates made of, for example, fiber reinforced plastic. It is formed into a symmetrical concave shape, and these plate materials are bonded together in a liquid-tight manner to form a panel shape.
[0056]
That is, a plurality of tubular members 32a to 32c are formed on the panel 31 formed by bonding these two plate members 31a and 31b to each other, with the drain outlet side formed by a pair of opposing symmetric recesses inclined downward. In addition, the communication pipe 33a is formed so as to be connected to the uppermost tubular member 32a.
[0057]
The uppermost tubular member 32a is connected at its lower end to the upper end of the middle tubular member 32b by a communication pipe 33b. Similarly, the lower and upper ends of the upper and middle tubular members 33a, 33b are connected at a drain pipe 34a. Has been.

[0060]
And the connection port 35 for connecting an air valve is shape | molded by the upper part of the water supply side edge part of the uppermost tubular member 32a.
[0061]
The panel 31 is completed by joining the plate materials 31a and 31b made of the two fiber-reinforced plastics thus formed in a liquid-tight manner.
[0062]
The panel 31 can be housed and installed in a thin box (not shown) and embedded in, for example, a kitchen wall.
[0063]
Moreover, if the panel 31 is comprised with a transparent fiber reinforced plastic, the residual state and flow of internal water can be monitored.
[0064]
As described above, the inside of each tubular member constituted by the panel 31 sequentially flows without dead water due to the use of tap water, and water is always secured in the water storage channel constituted by these tubular members.
[0065]
Further, in an emergency, the water pressure is lost, the air valve is opened by opening the lower water supply current, and the tap water in each of the tubular members 32a to 32c flows down through the communication pipes 33b and 33c and the drain pipes 34a and 34b. Then, it flows sequentially from the lowermost tubular member 32c to the drain port 36, the communication pipe 33d, and the water supply curan, and all the stored water can be discharged.

【The invention's effect】
The present invention has the following effects.
[0073]
(A) According to the first aspect, water flows in sequence by the use of tap water, and water is always secured in the water storage channel constituted by these tubular members in a state without dead water. In an emergency, an air valve that is always closed by water pressure is opened by opening the lower water supply curan, so that a large amount of water stored in these tubular members can be used by natural fall. In particular, since this water supply apparatus is an assembly of separate thin tubular members, the strength is high and the flow of water is smooth. Furthermore, normally, tap water enters from the inlet of the tubular member flows inside the tubular member, flows from the drain outlet at the end to the next tubular member, water flows in a zigzag efficiently, and no dead water is generated. . This is because the water flow resistance is smaller than that of the flow path in which the communication portion connecting the introduction port and the drain port is located on the opposite side. In an emergency, the communicating portion having a large resistance to flowing water cooperates with the communication path connecting the inlet and the drain to cause the water to flow downward, so that the water remaining in the tubular member can be prevented as much as possible.
[0074]
(B) According to claim 2, since the discharge port of the tubular member exists at the lowermost end portion of the tubular member at the time of natural fall of water in an emergency, almost all of the water falls and the remaining water remains. Can be prevented. Moreover, when water supply to these tubular members is started after emergency water flow, the air inside can be discharged from the upper air valve without leaving any air.
[0076]
( C ) According to claim 4 , the communication portion having a large resistance to flowing water works in the same manner as in claim 2, and even if the tubular member is tilted, the flow of water is promoted and the water supply to the water supply is improved. When started, the air inside can be effectively discharged from the upper air valve without leaving any air inside.
[0077]
( D ) According to claim 7 , mass production becomes possible, and the manufacturing cost can be reduced.
[0078]
( E ) According to claim 8 , the emergency water supply pipe is not destroyed by an external force, and a space around the air valve is secured even when the emergency water supply pipe is embedded in the wall. The
