【発明の属する技術分野】
本発明は、排水を下水等に排出する各種の排水管のうち、比較的多量の、もしくは複数の排水管からの排水を合流させて流す排水主管と、該排水主管に比較的少量の排水を流し込んで合流させる排水枝管と、を接続する排水合流管の改良に関する。
【０００２】
【従来の技術】
従来より、排水配管の部材の１つとして、比較的多量の、もしくは複数の排水管からの排水を合流させて流す排水主管と、該排水主管に比較的少量の排水を流し込んで合流させる排水枝管と、を接続する排水合流管が良く知られている。
【０００３】
これらの排水合流管の構造は極めて単純で、通常は、図１０に示したように、円筒状の主管部に、側面方向からやはり円筒状の枝管部を設けた構造であり、主管部においては上流側からの排水はそのまま下流側に流れ、また枝管部側からの排水は接続箇所で下方に曲がって主管部に合流し、主管部の下流側から排水が行われるようになっている。これらの具体的な配管例としては、図１２に示したように、マンション等の複数階を有する建物の、高層階からの排水を流す排水主管に、個々の階の排水を行う横方向の排水枝管を接続させる排水合流管や、図１３に示したように、洗面台のオーバーフロー口と排水配管を合流させる排水合流管、また図１４に示したように、流し台において、シンク側からの排水を流す排水主管に、側面方向からポケットシンクと呼ばれる排水装置からの排水枝管を接続した排水合流管がある。
【０００４】
【発明が解決しようとする課題】
上記のような排水合流管において、排水が主管部を、図１１に示した矢印のように流れる場合、枝管部との接合部を通過する際に、枝管部側の空気を引き込んでゆくサイフォン現象と呼ばれる現象が発生する。このサイフォン現象が生じると、図１２の高層住宅の場合であれば、排水枝管の先に接続されている排水装置などに異常が生じる。特に配管先の排水装置が排水トラップと呼ばれる、下水側からの異臭や害虫類が屋内に侵入するのを防止した機能を備えた排水装置であれば、破封と呼ばれる現象が生じて排水トラップの機能が損われ、下水側からの異臭や害虫類が屋内に侵入してくる場合がある。また、図１３に示した洗面台や、図１４に示した流し台等、屋内の排水機器の場合は、排水枝管側に空気の引き込みによる不快音（通常「ごぼごぼ」と表現される音である）が発生し、さらに排水中に空気が混入するため、下流に向かう排水の流れに空気の泡がブレーキを掛け、排水のスピードが著しく悪化する。特に通常見られるように排水主管が上下に配管されている場合は、空気の泡が排水の流れに逆らって上昇するため、この排水スピードの低下作用の影響が大きくなる。本発明は上記問題点に鑑み考案されたもので、排水合流管において、排水主管部に排水が行われても、排水枝管部側にサイフォン現象の生じない排水合流管を提供するものである。

【００１３】
【発明の実施の形態】
本発明の第一実施例を、図面を参照しつつ説明する。図１乃至図３に示した本発明の第一実施例は、図３に示したようにマンション等の複数階を有する建物に用いられ、以下のように構成された排水合流管（１）によって、高層階からの排水を流す排水主管（６）に、個々の階の排水を行う横方向の排水枝管（７）が接続されている。排水合流管（１）は、図１に示したように、縦方向に排水が流れる主管部（２）と、該主管部（２）の側面方向に突出するようにして設けられた、主管部（２）側に排水を流入させる枝管部（３）と、から成り、枝管部（３）側の排水の流入箇所が水平方向に開放され、且つ略水平状に設けられている。更に、主管部（２）から流れる排水と枝管部（３）から流れる排水との合流箇所に、排水流入機構として、枝管部（３）側に排水の一部を流入させる流入板（５ａ）を、主管部（２）に向けて枝管部（３）下端から略水平状に設けてなる。また、枝管部（３）に、排水枝管（７）から排水主管（６）に向かう流れの排水は通すが、排水主管（６）から排水枝管（７）に向かう流れの排水は通さない逆流防止機構として、逆流防止弁（４）を設けてなる。
【００１４】
配管先の排水機器（Ｄ）の使用によって、上層階の排水枝管（７）を介し排水主管（６）に排水が流れ込む場合、排水の生じた排水合流管（１）よりも下方に配管されている排水合流管（１）においては、排水の流れは図２の矢印に示したように、主管部（２）を通る排水の一部が流入板（５ａ）に当たってその一部が枝管部（３）側に流入し、逆流防止弁（４）が作動して、枝管部（３）と排水枝管（７）との接続箇所が閉塞される。このように逆流防止弁（４）の作動によって排水合流管（１）と排水枝管（７）との接続が閉塞されたことで、排水枝管（７）側からの空気の引き込みが発生しなくなり、不快音や、排水枝管（７）の先に接続されている排水装置に異常が生じなくなる。特に配管先の排水機器（Ｄ）に排水装置として排水トラップが用いられている場合、排水トラップに破封が生じなくなる。
【００１５】
次に本発明の第二実施例を、図面を参照しつつ説明する。図４乃至図７に示した本発明の第二実施例は、図６に示した洗面台（Ｓ）や、図７に示した流し台（Ｋ）など、屋内の排水機器（Ｄ）に用いられ、各排水機器（Ｄ）に取り付けられた排水装置と床下の横引き配管を接続する、上下に配置された排水主管（６）中に接続される排水合流管（１）であって、図４に示したように、縦方向に排水が流れる主管部（２）と、該主管部（２）の側面方向に突出するようにして設けられた、排水主管（６）側に排水を流入させる枝管部（３）と、から成り、更に、主管部（２）の流入側と流出側を、主管部（２）から流れる排水と、枝管部（３）から流れる排水との合流箇所において、枝管部の反対方向に、主管部の内側の直径よりも小さい幅だけ偏芯させ、偏芯によって生じた壁面を、排水の流入箇所が水平方向に開放され、且つ略水平状である、排水流入機構である流入壁（５ｂ）として構成してなる。また、枝管部（３）に、排水枝管（７）から排水主管（６）に向かう流れの排水は通すが、排水主管（６）から排水枝管（７）に向かう流れの排水は通さない逆流防止機構として逆流防止弁（４）を設けてなる。
【００１６】
洗面台（Ｓ）や流し台（Ｋ）等、排水機器（Ｄ）の使用によって、排水装置から排水主管（６）に排水が流れた場合、排水の流れは図５の矢印に示したように、排水合流管（１）の流入壁（５ｂ）に排水が当たってその一部が枝管部（３）側に流入し、逆流防止弁（４）が作動して、枝管部（３）と排水枝管（７）との接続箇所が閉塞される。このように逆流防止弁（４）の作動によって排水合流管（１）と排水枝管（７）との接続が閉塞されたことで、排水枝管（７）側からの空気の引き込みが発生しなくなり、不快音や、排水枝管（７）の先に接続されている排水装置（ポケットシンク等）に負圧などが生じなくなる。特にこの場合、排水中に空気の泡が発生しないため、排水のスピードが従来に比べて極めて早く、良好になる。
【００１７】
本発明の実施例は上記のようであるが、本発明は上記実施例に限定されるものでは無く、発明の要旨を変更しない範囲で自由に変更が可能である。例えば、上記各実施例においてはいずれも主管部（２）が上下方向を向くように配管されているが、主管部（２）を平面に対してほぼ並行となるように配管しても良い。この場合でも、本発明の排水合流管（１）は排水枝管（７）側にサイフォン現象が発生することを防止し、排水装置等に異常な負圧などが発生することを防止する。
【００１８】
また、上記各実施例においてはいずれも排水枝管（６）側に逆流防止機構を備えているが、排水流入機構によって排水枝管（６）側に排水が流入し、その勢いによって排水枝管（７）側からの流れが押し止められ、排水枝管（７）が閉塞されるのと同じ効果が得られるため、排水合流管（１）に排水流入機構を設けるだけでも本発明の目的を達成することができる。もちろん、枝管部（３）側に逆流防止機構を備えた方が、本発明の効果をより確実に得られることは言うまでもない。
【００１９】
また、排水合流管（１）の形状なども上記各実施例に限定されるものではなく、例えば図８に示したように、枝管部（３）と対向する箇所に流入壁（５ｂ）を設けても良い。この様な場合でも、図９の矢印に示したように、排水合流管（１）の流入壁（５ｂ）に排水が当たってその一部が、排水の流入箇所が水平方向に開放され、且つ略水平状である、枝管部（３）側に流入し、逆流防止弁（４）が作動して、枝管部（３）と排水枝管（７）との接続箇所を閉塞することができ、本発明の目的を達成できる。
【００２０】
また、上記各実施例においては、逆流防止機構である逆流防止弁（４）を、排水合流管（１）の枝管部（３）内に配置しているが、逆流防止機構が機能するのであれば、配置箇所を排水枝管（７）内としても、本発明の目的を達成することができる。
【００２１】
【発明の効果】
本発明は上記のように構成したため、以下のような優れた効果を奏する。
１）請求項１または請求項２、請求項３、請求項４による本発明においては、排水主管及び排水枝管からなる排水合流管において、排水枝管下端や主管部（２）の枝管部（３）と対向する箇所に排水流入機構を設けたことで、異音や排水枝管側へのサイフォン現象の発生を防止し、また排水性能を向上させることができる。
２）請求項１乃至請求項５による本発明においては、排水枝管部に逆流防止機構、特に逆流防止弁を備えたことで、サイフォン現象の発生防止などの本発明の効果をより確実に得ることができる。

BACKGROUND OF THE INVENTION
The present invention relates to a drainage main pipe that circulates a relatively large amount or drainage from a plurality of drainage pipes, and a relatively small amount of drainage to the drainage main pipe among various drain pipes that discharge wastewater to sewage. The present invention relates to an improvement of a drainage junction pipe that connects a drainage branch pipe that is poured and joined.
[0002]
[Prior art]
Conventionally, as one of the drainage pipe members, a drainage main pipe that joins and flows a relatively large amount of drainage from a plurality of drainage pipes, and a drainage branch that flows and joins a relatively small amount of drainage into the drainage main pipe A drainage junction pipe connecting the pipe and the pipe is well known.
[0003]
The structure of these drainage merging pipes is very simple. Usually, as shown in FIG. 10, a cylindrical main pipe part is provided with a cylindrical branch pipe part from the side direction. The drainage from the upstream side flows downstream as it is, and the drainage from the branch pipe part is bent downward at the connection point and joins the main pipe part, and the drainage is performed from the downstream side of the main pipe part. . As concrete examples of these pipes, as shown in FIG. 12, horizontal drainage for draining individual floors to a drainage main pipe for draining water from a higher floor of a building having a plurality of floors such as an apartment. The drainage junction pipe connecting branch pipes, the drainage junction pipe joining the overflow port of the sink and the drainage pipe as shown in FIG. 13, and the drainage from the sink side in the sink as shown in FIG. There is a drainage merging pipe in which a drainage branch pipe from a drainage device called a pocket sink is connected to the main drainage pipe from the side.
[0004]
[Problems to be solved by the invention]
In the drainage merging pipe as described above, when the drainage flows through the main pipe part as shown by the arrow in FIG. 11, the air on the side of the branch pipe part is drawn when passing through the joint part with the branch pipe part. A phenomenon called siphon phenomenon occurs. When this siphon phenomenon occurs, in the case of the high-rise house of FIG. 12, an abnormality occurs in the drainage device connected to the tip of the drainage branch pipe. In particular, if the drainage device at the end of the pipe is called a drainage trap, and a drainage device with a function that prevents the entry of odors and pests from the sewage side into the room, a phenomenon called breakage occurs, The function is impaired, and there is a case where a strange odor or pest from the sewage enters the room. Further, in the case of indoor drainage equipment such as the wash basin shown in FIG. 13 and the sink shown in FIG. 14, an unpleasant sound (usually expressed as “garbage”) due to air drawing into the drainage branch pipe side. Sound) and air is mixed into the wastewater, and air bubbles brake the flow of the wastewater going downstream, and the speed of the wastewater is significantly deteriorated. In particular, when the drainage main pipe is vertically installed as normally seen, the bubbles of air rise against the flow of drainage, so that the effect of this drainage speed lowering effect is increased. The present invention has been devised in view of the above problems, and provides a drainage junction pipe that does not cause siphoning on the drainage branch pipe side even when drainage is performed on the drainage main pipe part. .
