Description

【0001】
【発明が属する技術分野】
本発明は、各種設備機器から排水される排水を下水管へと排出する、排水装置に関するものである。
【0002】
【従来の技術】
従来より、浴室や洗濯機等の防水パン、又は洗面台や流し台のような槽体等、使用によって排水を生じる機器(以後「排水機器」と呼ぶ)には、機器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、排水装置が用いられている。その排水装置の中では、例えば下水側の臭気や害虫類が逆流してくるのを防止する、排水トラップと呼ばれる排水装置がよく知られている。
【0003】
該排水トラップを例に挙げると、従来利用されている図7及び図8に示した排水トラップは、以下に記載したケーシングと蓋部から成るトラップ本体、フランジ部材、防臭筒の各部材より構成されて成る。ケーシングは、上部が開口され、有底筒状の封水部と、封水部の側壁の途中位置に底壁を設けた通水路と、通水路の側面に設けた排出口と、から成る。蓋部は、ケーシングの開口に接合され、後記するフランジ部材の雄螺子と螺合する雌螺子を備えた接続部を開口して成る。前記ケーシングと前記蓋部は、水密的に接合されてトラップ本体を構成して成る。フランジ部材は、筒状の内部に排水口を備えると共に、外周部に前記蓋部の接続部の雌螺子と螺合する雄螺子を備えて成る。防臭筒は、上下に開口した略円筒状の部材で、上方側はフランジ部材に水密的に且つ着脱自在に取り付けられ、下方側は封水部に配置される。
【0004】
また、前記した排水トラップの構成と別構成の排水トラップとして、ランニングトラップと呼ばれる排水トラップがある。従来利用されているランニングトラップは、図9及び図10に示し、以下に記載した、ケーシングと蓋部から成るトラップ本体、フランジ部材、の各部材より構成されて成る。ケーシングは、上部に開口を設けると共に、側面に設けられた排出口と、底面から立ち上がる立ち上がり壁と、立ち上がり壁を設けたことで形成される防臭椀部と、該防臭椀部内に設けられる、封水を形成するための下部が開放された隔壁部と、から成る。前記ケーシングと前記蓋部は、水密的に接合されてトラップ本体を構成して成る。蓋部は、ケーシングの開口に水密的に接合され、後記するフランジ部材の雄螺子と螺合する雌螺子を備えた接続部を開口して成る。フランジ部材は、筒状の内部に排水口を備えると共に、外周部に前記蓋部の開口と螺合する雄螺子を備えて成る。
【0005】
上記した排水トラップは、例えば防水パンなどの排水機器に取り付けられる。防水パンに排水トラップを取り付ける方法としては、防水パンに設けられた取着孔に、水密部材を介してフランジ部材と、蓋部の接続部とで該取着孔を挟持するように取り付けられている。前記防水パン等に排水を行うと、排水はフランジ部材の排水口から防臭筒または隔壁を通って封水部に溜まり、この封水部の上端から溢れだした水が通水路又は排水流路を通り、排出口より排出される。他方、下水側から臭気や害虫類等が逆流してきた場合は、この封水部に溜まっている水によってそれらの進入を防止することができる。
【0006】
上記の構成の排水トラップにおいては、排水トラップの使用時に漏水など無いように、トラップ本体を製造する際に、ケーシングと蓋部を何らかの手法によって水密的に接合しなければならない。この接合方法の例として、ケーシングと蓋部が共に合成樹脂製で有れば接着剤によって接着する方法や、熱や超音波による微細振動のエネルギーで樹脂を溶融して接合する、溶着という方法がある。通常、接着剤での接合方法としては、ケーシングまたは蓋部の片方に接着剤を塗布し、両者を貼合せ、貼合せ後両者が動かないようにクリップやクランプ等の治具を用いたり、組立作業者の手で直接固定したまま接着剤が硬化するまで養生させることによって接合が完了する。また、溶着の接合方法としても、部材同士が動かないようにクリップやクランプ等の治具、または組立作業者の手で直接固定した状態から、熱や超音波による溶着によって接合していた。
【0007】
従来から前記トラップ本体のケーシングと蓋部の接合方法としては、前記した接着剤での接合や、溶着による接合で行われているが、以下に記載したような問題点があった。
【0008】
【発明が解決しようとする課題】
接着剤による接合時に、ケーシングと蓋部が動かないように、組立作業者の手で直接固定したまま接着剤が硬化するまで養生させる方法では、組立生産時に非常に手間になるばかりか、更には人件費がかさみコストアップとなっていた。また、溶着時にケーシングと蓋部が動かないように、組立作業者の手で直接固定したまま溶着部位が硬化するまで養生させると、溶着の際の熱等が作業者にとって非常に危険であった。また、接着や溶着時にケーシングと蓋部が動かないように、接合後クリップやクランプ等の治具を用いて位置固定したまま接着剤が硬化するまで養生させる方法では、接合後クリップやクランプでケーシングと蓋部を位置固定し、接合部位が硬化後また取り外す、といった工程が増えて効率が悪くなり、更にはクリップやクランプを組立生産する個数分用意しなければならず、コストアップとなっていた。
【0009】
更に、上述した作業者の手で直接固定したり、クリップやクランプを用いて接合部位を養生させる方法では、ケーシングと蓋部が傾いたりするなど、誤って不完全に接合されていても発見される可能性は低く、排水装置の施工が完了し、排水装置の取り替えや修正が極めて困難になってから、実使用の際に接合部分からの漏水発生で接合不良が発見されるため、接合部位の修正や排水装置自体の取り替えなどの解決手段を施すことが非常に難しかった。
【0010】
また、ケーシングと蓋部を接合させる際、前記段落0004に記載した排水トラップのようにケーシング内に隔壁部があり、該隔壁部と蓋部を水密的に接合させなければならない場合には、ケーシングの開口は蓋部で覆われるのでケーシング内部での隔壁部と蓋部の接合部位が目視できないため、確実に接合されているか否かを確かめるには別途水圧テスト等でテストを行わなければならなかった。本発明は上記した問題点を解決するために発明されたものである。
【0011】
【課題を解決する手段】
本発明の排水装置は、排水機器の排水を処理する、上部が開口(10)された箱体から成るケーシング(2)と、該ケーシング(2)の開口(10)を覆って、ケーシング(2)と水密的に接合する蓋部(3)と、から構成される排水装置において、
ケーシング(2)外周面上方に設けられた断面視山形形状で外側方向に凸設された係合凸部(4a)から構成されるケーシング(2)の係合部(4)と、蓋部(3)の下方に向けて垂下され、前記係合凸部(4a)と係合するための孔を有した係合孔部(4e)が孔設された係合爪部(4d)と、該係合爪部(4d)先端から内側方向に向けて設けられた片側テーパ部(4f)とで形成される蓋部(3)の係合部(4)と、を構成し、蓋部(3)とケーシング(2)の開口(10)とを接着剤によって接合し、該係合部(4)をケーシング(2)と蓋部(3)を位置固定すると共に、接着剤の養生を行うために設けたことを特徴とする排水装置である。
【0012】

【0013】
本発明の排水装置は、前記排水装置を防臭・防虫機能を備えた排水トラップとしたことを特徴とする前記段落0011又は前記段落0012のいずれかに記載の排水装置である。
【0014】
【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乃至図3に示した、本発明の第一実施例の排水装置は、ケーシング(2)と蓋部(3)から成るトラップ本体(1)、防臭筒(7)、より構成される排水トラップである。ケーシング(2)は、上部が開口(10)され、有底筒状の封水部と、封水部の側壁の途中位置に底壁を設けた通水路と、通水路の側面に設けた排出口と、から成る。蓋部(3)は、ケーシング(2)の開口(10)に接合され、後記するフランジ部材(6)の雄螺子と螺合する雌螺子を備えた接続部(3a)を開口して成る。前記ケーシング(2)と前記蓋部(3)は、水密的に接合されてトラップ本体(1)を構成して成る。フランジ部材(6)は、筒状の内部に排水口を備えると共に、外周部に前記蓋部(3)の接続部(3a)の雌螺子部と螺合する雄螺子を備えて成る。防臭筒(7)は、上下に開口した略円筒状の部材で、上方側はフランジ部材(6)に水密的に且つ着脱自在に取り付けられ、下方側は封水部に配置される。
【0015】
また、該トラップ本体(1)のケーシング(2)と蓋部(3)には、それぞれ数カ所下記に示した係合部(4)が備えられている。ケーシング(2)側の係合部(4)は、ケーシング(2)外周面上方に設けられた断面視山形形状で外側方向に凸設された係合凸部(4a)であり、更に詳しくは、乗越部(4c)を有し、且つ山形テーパ部(4b)とで形成される係合凸部(4a)である。また蓋部(3)の係合部(4)は、前記係合凸部(4a)と係合する孔が孔設された係合孔部(4e)であり、更に詳しくは、蓋部(3)の下方に向けて垂下され、且つ前記係合孔部(4e)が孔設された係合爪部(4d)と、該係合爪部(4d)先端から内側方向に向けて設けられた片側テーパ部(4f)とで形成される係合孔部(4e)である。
【0016】
上記トラップ本体(1)は、蓋部(3)をケーシング(2)の開口(10)に水密的に接合するために、接着剤によって接合されるが、この接合の組立工程としては、蓋部(3)に接着剤を塗布し、ケーシング(2)の開口(10)に覆い被せて蓋部(3)を位置決めする。このとき、蓋部(3)とケーシング(2)の両者が正しい位置関係にて接合されていると、両部材の係合部(4)が係合されて、蓋部(3)とケーシング(2)が相互に位置固定される。該係合部(4)の作用としては、図3(a)に示したように、まず係合爪部(4d)の片側テーパ部(4f)が係合凸部(4a)の山形テーパ部(4b)に当接し、図3(b)に示したように係合爪部(4d)が外側方向にたわみながら係合爪部(4d)の片側テーパ部(4f)が係合凸部(4a)の山形テーパ部(4b)上を摺動して乗越部(4c)を乗り越え、図3(c)に示したように、係合孔部(4e)に係合凸部(4a)を係合させることができる。この係合部(4)の作用により、蓋部(3)とケーシング(2)の位置固定が容易且つ確実に出来、位置固定のための余計な治具などが必要ない。また、係合部(4)を設けたことによってケーシング(2)と蓋部(3)が係合し、位置決め固定されているため、従来例に記載したようなクランプや作業者の手を使わずにでも接着剤の養生を行うことができる。以上のことにより、ケーシング(2)と蓋部(3)は接着剤による接合でより強固に、かつ水密的に接合される。
【0017】
また、上記のように構成した排水トラップの施工方法、施工構成は前記従来例に記載した排水トラップと同じ施工方法、施工構成である。
【0018】
以下に本発明の第二実施例を、図面を参照しつつ説明する。図3乃至図5に示した、本発明の第二実施例の排水装置は、ケーシング(2)と蓋部(3)から成るトラップ本体(1)、フランジ部材(6)、より構成されるランニングトラップである。ケーシング(2)は、上部に開口を設けると共に、側面に設けられた排出口と、底面から立ち上がる立ち上がり壁と、立ち上がり壁を設けたことで備えられる防臭椀部(8)と、該防臭椀部(8)内に設けられる、封水部を形成するための下部が開放された隔壁部(5)と、から成る。前記ケーシング(2)と前記蓋部(3)は、水密的に接合されてトラップ本体(1)を構成して成る。蓋部(3)は、ケーシング(2)の開口(10)に水密的に接合され、後記するフランジ部材(6)の雄螺子と螺合する雌螺子を備えた接続部を開口して成る。フランジ部材(6)は、筒状の内部に排水口を備えると共に、外周部に前記蓋部(3)の接続部(3a)と螺合する雄螺子を備えて成る。
【0019】
また、該トラップ本体(1)のケーシング(2)と蓋部(3)には、それぞれ数カ所下記に示した係合部(4)が備えられ、更にケーシング(2)内の隔壁部(5)と、それに対応する係合部(4)が蓋部(3)に備えられている。ケーシング(2)側の係合部(4)は、ケーシング(2)外周面上方に設けられた断面視山形形状で外側方向に凸設された係合凸部(4a)であり、更に詳しくは、乗越部(4c)を有し、且つ山形テーパ部(4b)とで形成される係合凸部(4a)である。隔壁部(5)の係合部(4)は、隔壁部(5)の一方の上方面に設けられた断面視山形形状で外側方向に凸設された係合凸部(4a)であり、更に詳しくは、乗越部(4c)を有し、且つ山形テーパ部(4b)とで形成される係合凸部(4a)である。また蓋部(3)の係合部(4)は、前記係合凸部(4a)と係合する孔が孔設された係合孔部(4e)であり、更に詳しくは、蓋部(3)の下方に向けて垂下され、且つ前記係合孔部(4e)が孔設された係合爪部(4d)と、該係合爪部(4d)先端から内側方向に向けて設けられた片側テーパ部(4f)とで形成される係合孔部(4e)である。
【0020】
トラップ本体(1)は、蓋部(3)をケーシング(2)の開口(10)に水密的に接合するために、前記段落0017に記載した方法または作用によって接合され、更にケーシング(2)内部の隔壁部(5)にも同様の作用が発生する。これは、蓋部(3)の係合孔部(4e)がケーシング(2)の係合凸部(4a)に係合することによって、蓋部(3)がケーシング(2)の開口(10)に覆い被さるように接合されて、内部の接合部位が目視確認できなくても、確実に接着剤が硬化するまで位置決め箇所のまま養生することが可能となり、より確実な接合となる。
【0021】
また、上記のように構成した排水トラップの施工方法、施工構成は前記従来例に記載した排水トラップと同じ施工方法、施工構成である。
【0022】
また、上記した排水装置としての排水トラップ以外にも、例えば図6に示したようにレリースワイヤなどを用いて浴槽や洗面ボウル内の排水栓を遠隔操作によって開閉する遠隔操作式排水栓装置(12)に接続され、内部は単純に排水を流すだけのエルボ部材(11)なども本発明の排水装置として相当する。
【0023】
【発明の効果】

[Technical field to which the invention belongs]
The present invention relates to a drainage device that discharges drainage drained from various equipment to a sewer pipe.
[0002]
[Prior art]
Conventionally, drainage generated by use of equipment is used for equipment that generates drainage by use, such as waterproof pans such as bathrooms and washing machines, or tank bodies such as washstands and sinks. A drainage device is used for wastewater treatment on the sewage side. Among such drainage devices, for example, drainage devices called drain traps that prevent sewage-side odors and pests from flowing back are well known.
[0003]
Taking the drain trap as an example, the drain trap shown in FIG. 7 and FIG. 8 that has been conventionally used is composed of a trap body, a flange member, and a deodorizing cylinder composed of a casing and a lid as described below. It consists of The casing is formed of a bottomed cylindrical sealed water portion, a water passage having a bottom wall in the middle of the side wall of the water seal portion, and a discharge port provided on a side surface of the water passage. The lid portion is formed by opening a connection portion that is joined to an opening of the casing and includes a female screw that is screwed with a male screw of a flange member described later. The casing and the lid are watertightly joined to constitute a trap body. The flange member is provided with a drain outlet inside a cylindrical shape, and a male screw that engages with a female screw of the connecting portion of the lid portion on the outer peripheral portion. The deodorizing cylinder is a substantially cylindrical member opened up and down, the upper side is attached to the flange member in a water-tight and detachable manner, and the lower side is arranged in the water sealing portion.
[0004]
Further, there is a drain trap called a running trap as a drain trap having a configuration different from that of the drain trap. Conventionally used running traps are shown in FIG. 9 and FIG. 10, and are composed of the trap main body composed of a casing and a lid, and a flange member described below. The casing is provided with an opening at the top, a discharge port provided on the side surface, a rising wall rising from the bottom surface, a deodorizing gutter part formed by providing the rising wall, and a sealing provided in the deodorizing gutter part. And a partition wall having a lower portion for forming water. The casing and the lid are watertightly joined to constitute a trap body. The lid portion is formed by opening a connecting portion that is watertightly joined to the opening of the casing and includes a female screw that is engaged with a male screw of a flange member described later. The flange member is provided with a drain outlet inside a cylindrical shape, and a male screw that is screwed into the opening of the lid portion on the outer peripheral portion.
[0005]
The drain trap described above is attached to a drain device such as a waterproof pan. As a method of attaching the drain trap to the waterproof pan, it is attached to the attachment hole provided in the waterproof pan so that the attachment hole is sandwiched between the flange member and the connection portion of the lid portion through the watertight member. Yes. When draining to the waterproof pan or the like, the drainage is accumulated in the sealed water part through the deodorizing tube or the partition wall from the drain port of the flange member, and the water overflowing from the upper end of the sealed water part passes through the water channel or the drainage channel. Street is discharged from the outlet. On the other hand, when odors, pests, and the like flow backward from the sewage side, they can be prevented from entering by the water accumulated in the sealing portion.
[0006]
In the drain trap having the above-described configuration, the casing and the lid must be joined in a watertight manner by some method when the trap body is manufactured so that there is no leakage when the drain trap is used. As an example of this joining method, if the casing and the lid are both made of synthetic resin, there are a method of adhering with an adhesive, and a method of welding, in which the resin is melted and joined by the energy of fine vibrations by heat or ultrasonic waves. is there. Usually, as a method of joining with an adhesive, apply adhesive on one side of the casing or lid, paste both together, and use a jig such as a clip or clamp to prevent both from moving after assembly, Joining is completed by curing until the adhesive is cured while being directly fixed by the operator's hand. In addition, as a welding joining method, welding is performed by heat or ultrasonic welding from a state where the members are fixed directly by a jig such as a clip or a clamp, or an assembly operator so that the members do not move.
[0007]
Conventionally, as a method of joining the casing and the lid of the trap body, the above-described joining with an adhesive or joining by welding has been performed. However, there are problems as described below.
[0008]
[Problems to be solved by the invention]
In order to prevent the casing and lid from moving during bonding with the adhesive, the method of curing until the adhesive is cured while directly fixing by the hand of the assembly operator is not only very troublesome during assembly production, but also Labor costs were high and cost increased. Also, if the welded part is cured while being fixed directly by the assembly operator's hand so that the casing and the lid do not move during welding, the heat during the welding is extremely dangerous for the worker. . In addition, in order to prevent the casing and lid from moving during bonding and welding, after curing, the casing is secured with the clip or clamp after bonding. And the lid part is fixed, the process of removing the joint part after curing is increased, the efficiency becomes worse, and furthermore, it is necessary to prepare the number of clips and clamps for assembly production, which increases the cost. .
[0009]
Furthermore, in the method of fixing directly by the above-mentioned operator's hand or curing the joining part using a clip or a clamp, the casing and the lid part are tilted. Since it is very difficult to replace and modify the drainage device after the construction of the drainage device is completed, it is very difficult to replace the drainage device. It was very difficult to implement solutions such as correction of the water and replacement of the drainage device itself.
[0010]
Further, when the casing and the lid are joined, there is a partition wall in the casing like the drain trap described in the paragraph 0004, and the casing and the lid must be joined in a watertight manner. Since the opening is covered with a lid, the joint between the partition wall and the lid inside the casing cannot be seen, so a separate water pressure test etc. must be performed to ascertain whether or not they are securely joined. It was. The present invention has been invented to solve the above problems.
