Description

【０００１】
【産業上の利用分野】
本発明は屋内の浴室、防水パン等に用いられる排水トラップに関するものである。
【０００２】
【従来の技術】
従来より、屋内の浴室、また洗濯機等に用いられる防水パン等には、機材の利用によって生じた排水を下水側に排水処理するために排水装置が用いられている。これら排水装置の中で、下水側からの臭気また害虫類等が、排水装置内を逆行して屋内側に進入することを防止する機能を備えた排水装置を特に排水トラップと呼んでいる。この排水トラップには様々な種類があるが、例えば図３に示したように、その内部に形成される排水流路の一部に排水を溜め（この防臭や防虫等を目的として溜めた排水を以後「封水」、またこの封水を形成する部分を以後「封水部」と呼ぶ）、この封水部で臭気や害虫類の逆行を防止する排水トラップが一般的である。
【０００３】
【発明が解決しようとする課題】
ところで、上記した封水部が防臭・防虫といった機能を十分に果たすためには、封水部を形成する、防臭筒部材の下端から防臭椀部の上端まで等の、封水を形成する部分の深さ（以後「封水深」と呼ぶ）を、充分な深さに設定するとともに、この部分に常時封水が満たされていなければならない。これを達成するために、たとえば日本工業規格（ＪＩＳ規格）においては、排水トラップにおけるこの封水深の深さを、「５０ｍｍ以上、１００ｍｍ以下」と定めており、また通常浴室等に用いられる排水トラップの封水深もこの値を遵守した構成となっている。
【０００４】
しかしながら、実際にこれら排水トラップを使用すると、排水トラップの封水部内の水位が防臭筒部材の筒体部下端以下の低さになって、排水トラップの防臭・防虫機能が損なわれる「破封」と呼ばれる現象が起きる場合がある。破封の発生する原因は様々であるが、そのうち最も頻度が多いのは、排水トラップの排出口から排水が排出される際に、排水に空気を巻き込んでサイホン作用という気圧の変化に伴う引き込み現象を発生させ、排水が排出口から下水側に必要以上に排出されてしまい、残った排水が少なすぎて封水を形成することができなくなる場合である。
本発明は上記問題点に鑑み発明されたものであって、
１）排水トラップから排水を流した際に、サイホン作用によって排水の引き込みが生じても、封水が充分に確保できるようにする。
２）上記１）を、排水トラップの上下方向の幅を広くすることなく達成する。
といった目的を達成できる排水トラップを提供するものである。
【０００５】

【０００６】
請求項２に記載の排水トラップは、上部に開口部（３）を設けると共に、側面に排出口（５）を設けたケーシングであって、更に開口部（２）と排出口（５）の間に底面から立ち上がる壁を設けることで開口部（３）の下方に防臭椀部（２）を形成し、また該防臭椀部（２）の上端から排出口（５）に向かって排水流路を形成した外壁部（４）より成るトラップ本体（１）と、内部に排水口（８）を形成する筒部（７）、筒部（７）の上縁外周に設けられたフランジ部（９）、から成り、トラップ本体（１）の開口部（３）と係着して排水トラップの取着を行うフランジ部材（６）と、上下に開口した筒体からなる筒体部（１１）、該筒体部（１１）の上縁外周に設けられた、上記フランジ部材（６）の排水口（８）と水密的に係合する係合部（１２）、から成り、上記排水口（８）との係合時に該筒体部（１１）の下方がトラップ本体（１）の防臭椀部（２）内に配置されて封水部を形成する防臭筒部材（１０）と、から構成した排水トラップにおいて、上記防臭筒部材（１０）の筒体部（１１）下端よりも高い位置に少なくともその一部が配置され、排水トラップの排水時には排水の一部を確保し、且つ排水完了時には確保した排水を封水部に流入させる封水確保部（１３）を、防臭椀部（２）の側面全周にて突出させるようにして設けたことを特徴とする排水トラップである。
【０００７】
【発明の実施の形態】
以下に本発明の第一実施例を、図面を参照しつつ説明する。図１及び図２に示した、本発明の第一実施例は、以下に記載したトラップ本体（１）、フランジ部材（６）、及び防臭筒部材（１０）、より構成されてなる。トラップ本体（１）は、上方に開口した有底筒状の防臭椀部（２）と、該防臭椀部（２）の開口を囲むように設けられ（ここで言う「囲むように設ける」とは、防臭椀部（２）の開口からのオーバーフロー水を、外側に漏らさないような状態に設けることを意味する）、且つ内部に排水流路を形成する外壁部（４）と、該外壁部（４）の側面に設けられた、排水を排水流路から下水側に排出する排出口（５）と、から成り、更に外壁部（４）の上面に、雌螺子を設けた開口部（３）と、排水トラップを防水パンに取付する際に防水パンに当接する取付面（２１）と、を有する。更に本実施例の排水トラップは、上記防臭筒部材（１０）の筒体部（１１）下端よりも高い位置に少なくともその一部が配置され、排水トラップの排水時には排水の一部を確保し、且つ排水完了時には確保した排水を封水部に流入される、防臭椀部（２）の側面全周を外周側に突出させて形成した封水確保部（１３）を設けてなる。また、フランジ部材（６）は、外周側面に上記トラップ本体（１）の開口部（３）の雌螺子と螺合する雄螺子を設けると共に、内部に排水口（８）を形成する筒部（７）と、筒部（７）の外周上縁に設けられたフランジ部（９）と、から成る。また、防臭筒部材（１０）は、上下に開口した筒体からなる筒体部（１１）と、該筒体部（１１）の上縁外周に設けられた、上記フランジ部材（６）の排水口（８）と水密的に係合する係合部（１２）と、から成り、更に、上記開口部（３）との係合時に該筒体部（１１）の下方がトラップ本体（１）の防臭椀部（２）内に配置されて封水部を形成する。
【０００８】
上記のように構成した排水トラップを、図１にあるように取着孔を設けた防水パンに取着する場合、まず、防水パン等に設けたトラップ取着孔（Ｗ１）に、トラップ本体（１）を、フランジ部材（６）のフランジ部（９）とトラップ本体（１）の取付面（２１）とで、該トラップ取着孔（Ｗ１）の周縁を挟着するようにして螺合させ取着する。次に、防臭筒部材（１０）の係合部（１２）を、筒体部（１１）の下端がトラップ本体（１）の防臭椀部（２）内に配置されるようにフランジ部材（６）の開口部（３）に係合させて排水トラップの取付が完了する。その後、排出口（５）に、排水トラップの排水が下水側に排出できるように傾斜を設定した管部材を接続し下水側の管部材に接続する。
【０００９】
上記のように取付した排水トラップに、排水口（８）から排水を行うと、排水は防臭筒部材（１０）内を落下し、防臭筒部材（１０）の下端から防臭椀部（２）内を上昇し、上端部をオーバーフローして外壁部（４）内の排水流路に流れ込み、最終的には排出口（５）から下水側に排出される。また、この排出の際にサイホン作用によって排水が引き込まれた場合でも、封水確保部（１３）に確保・残留していた排水が封水部に流入して、防臭・防虫機能を維持するのに充分な量の封水を確保することができる。
【００１０】
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なく、発明の要旨を変えない範囲で様々な変更が可能である。例えば、上記実施例においては、トラップ本体（１）とフランジ部材（６）の係着を螺合によって行っているが、この係着方法についても何らの限定をするものではなく、排水トラップを防水パンに適宜取着できるのであれば、どのような方法で係着しても構わない。
【効果】
【００１１】
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）本発明においては、排水エルボからの排水時に、サイホン作用によって排水が引き込まれた場合でも、封水確保部内に貯留した排水によって、封水部には防臭・防虫機能を維持するのに充分な量の排水を確保することができる。

[Industrial application fields]
The present invention relates to a drain trap used for indoor bathrooms, waterproof pans and the like.
[0002]
[Prior art]
2. Description of the Related Art Conventionally, drainage devices have been used for waterproofing pans and the like used in indoor bathrooms and washing machines to drain wastewater generated by the use of equipment to the sewage side. Among these drainage devices, a drainage device having a function of preventing odors, pests and the like from the sewage side from going backward in the drainage device and entering the indoor side is particularly called a drainage trap. There are various types of drain traps. For example, as shown in FIG. 3 , drainage is collected in a part of the drainage channel formed in the trap (for example, drainage collected for the purpose of deodorization and insect prevention). Hereinafter, “sealed water”, and the portion that forms this sealed water is hereinafter referred to as “sealed water portion”), and a drainage trap that prevents the odor and pests from reversing in the sealed water portion is common.

[Problems to be solved by the invention]
By the way, in order for the water-sealing part described above to sufficiently perform the functions of deodorizing and insect-proofing, the part of the water-sealing part that forms the water-sealing part, such as from the lower end of the deodorizing cylinder member to the upper end of the deodorizing bottle part, is formed. The depth (hereinafter referred to as “sealing depth”) must be set to a sufficient depth, and this portion must be filled with sealing water at all times. In order to achieve this, for example, in the Japanese Industrial Standard (JIS standard), the depth of the sealed water in the drain trap is defined as “50 mm or more and 100 mm or less”, and a drain trap usually used in a bathroom or the like.

However, when these drain traps are actually used, the water level in the sealed portion of the drain trap becomes lower than the lower end of the cylindrical portion of the deodorizing cylinder member, and the deodorization / insect control function of the drain trap is impaired. There is a case where the phenomenon called There are various reasons for the occurrence of severance, but the most frequent of these is the phenomenon of entrainment caused by changes in atmospheric pressure called siphon action by entraining air in the drainage when it is discharged from the drain trap outlet. This is a case where the wastewater is discharged from the outlet to the sewage side more than necessary, and the remaining wastewater is too small to form the sealed water.
The present invention was invented in view of the above problems,
1) When drainage is made to flow from the drainage trap, even if drainage is drawn in due to siphon action, sufficient sealing water can be secured.
