従来より、流し台、洗面台、浴槽・浴室、洗濯機パンなど、使用によって排水が生じる各種の生活機器（以下、「排水機器」と呼ぶ）には、使用によって生じた排水を床下配管など下水側等に排出する排水装置が取り付けられている。これら排水装置の中で、下水側からの臭気や害虫類が屋内側に進入することを防止する機能を備えた排水機器を特に排水トラップと呼ぶ。この排水トラップの構造には様々な種類があるが、一般的に良く知られている排水トラップは、排水の流路中に封水と呼ばれる必ず排水が溜まる部分を設け、この封水の部分を臭気や害虫類が通過できないことを利用して下水側からの臭気や害虫類が屋内側に進入することを防止する機能を備えた、封水式と呼ばれる排水トラップである。以下に従来よく知られた封水式の排水トラップを、図面を参照しつつ説明する。 Conventionally, for various household appliances that generate drainage when used, such as sinks, washstands, bathtubs / bathrooms, washing machine pans, etc. (hereinafter referred to as “drainage equipment”), the drainage generated by use is discharged into the sewage side such as underfloor piping. A drainage device is attached. Among these drainage devices, a drainage device having a function of preventing odors and pests from the sewage side from entering the indoor side is particularly called a drainage trap. There are various types of drain trap structures, but generally well-known drain traps are provided with a portion of the drainage channel that always collects drainage, called sealed water. It is a drainage trap called a sealed type that has the function of preventing odors and pests from the sewage side from entering the indoor side by utilizing the fact that odors and pests cannot pass through. A well-known sealed drainage trap will be described below with reference to the drawings.

排水トラップは、以下に記載するトラップ本体、防臭筒、ロックナットからなる。
トラップ本体は、有底略円筒形状であって、上方の開口を排水口とし、内部には排水が溜まる封水部を備え、更にトラップ本体の側面に該封水部を溢れた排水が流れる排出口を備えて成る。
更に、排水口の上端周縁に、周縁に沿って外周方向に向かって凸を連続して設けたフランジ部を備えてなると共に、排水口の外側面に雄ねじを設けてなる。
防臭筒は、上下に開口した筒状体からなり、上方の開口は排水口に水密的に接続され、下端はトラップ本体内の封水部内に配置される。
ロックナットは筒状にして内部にトラップ本体の雄ねじと螺合する雌ねじを備えて成る。
このような排水トラップは、次のような排水機器である流し台に施工される。
本発明の排水トラップが取り付けられる流し台は、流し台の使用者が作業を行う天板部と、天板部上の開口の内に設けられた、底面に排水トラップ取付用の取付孔を有するシンクと、該天板部の下方に配置されたキャビネット部と、をそれぞれ設けてなる。
The sealed water drain trap of the conventional example shown in FIG. 8 shows the drain trap constructed in the sink of a sink, and is comprised from each member described below.
The drain trap includes a trap body, a deodorizing cylinder, and a lock nut described below.
The trap body has a substantially cylindrical shape with a bottom, has an upper opening as a drain outlet, and has a sealed portion in which drainage is collected. Further, drainage overflows the sealed portion on the side of the trap body. Comprising an exit.
Furthermore, the upper end periphery of the drainage port is provided with a flange portion that is continuously provided with protrusions in the outer peripheral direction along the periphery, and a male screw is provided on the outer surface of the drainage port.
The deodorizing cylinder is composed of a cylindrical body that is opened up and down, the upper opening is connected to the drain outlet in a watertight manner, and the lower end is arranged in a sealed portion in the trap body.
The lock nut has a cylindrical shape and is provided with a female screw that is screwed into the male screw of the trap body.
Such a drain trap is constructed on a sink which is a drainage device as follows.
The sink to which the drain trap of the present invention is attached includes a top plate part on which the user of the sink works, a sink provided in the opening on the top plate part, and a sink having a drain trap mounting hole on the bottom surface And a cabinet portion disposed below the top plate portion.
上記段落０００３に記載された排水トラップは、以下のようにして流し台のシンクに取付施工される。
シンクの取付孔の周縁を間に介した状態で、フランジ部の下面とロックナットの上面とで、シンクの取付孔の周縁を挟むようにして、トラップ本体の雄ねじとロックナットの雌ねじを螺合させ、シンクに対してトラップ本体を固定させる。
また、上方の開口が排水口に水密的に接続され、下端がトラップ本体内の封水部内に配置されるように、防臭筒を排水トラップに接続する。
更に排出口をパイプ管からなる排水配管を介して床下配管に接続させ、排水トラップの施工が完了する。
The drain trap described in paragraph 0003 is attached to the sink of the sink as follows.
With the peripheral edge of the sink mounting hole in between, the lower surface of the flange portion and the upper surface of the lock nut sandwich the peripheral edge of the sink mounting hole, and the male screw of the trap body and the female screw of the lock nut are screwed together. Fix the trap body to the sink.
Further, the deodorizing cylinder is connected to the drain trap so that the upper opening is connected to the drain outlet in a watertight manner and the lower end is disposed in the sealed portion in the trap body.
Further, the discharge port is connected to the underfloor pipe through a drain pipe comprising a pipe pipe, and the construction of the drain trap is completed.
上記のように構成された排水トラップ配管において、流し台を使用し、流し台のシンク内に排水が行われると、排水は、排水口、防臭筒の上方の開口から下端の開口、封水部の上端を介して排出口に至り、最終的には床下配管から下水側等に排出される。
また、このとき封水部に排水が溜まることで、排水トラップ内に形成された排水流路（排水口から排出口に至るまでの排水の流れ路）の少なくとも一部、封水部に、排水が必ず溜まった状態が生じる。この封水部に溜まった排水は封水と呼ばれ、下水側から臭気や害虫類が逆流してきた場合でも、これら臭気や害虫類がこの封水を乗り越える事ができないため、屋内側に臭気や害虫類が進入することを防止することができる。
In the drain trap pipe configured as described above, when drainage is performed in the sink of the sink, drainage is performed from the drain opening, the opening above the deodorizing cylinder to the bottom opening, and the top end of the sealing portion. To the discharge port, and finally discharged from the underfloor piping to the sewage side.
Also, at this time, drainage is collected in the sealed water part, so that at least part of the drainage channel (drainage flow path from the drainage port to the discharge port) formed in the drainage trap, There will always be a state of accumulation. The drainage collected in this sealed water section is called sealed water, and even if odors and pests flow backward from the sewage side, these odors and pests cannot get over this sealed water. Pests can be prevented from entering.
上記のような封水式の排水トラップには、以下のような問題があった。
上記封水式の排水トラップにおいて、流し台の使用によって排水トラップ内に排水が流れてゆく際、排水配管中の空気や床下配管中の空気を巻き込んで排水が流れてゆくため、排水が完了するまで一時的に排出口側の気圧が下がる場合があり、これは「自己サイホン作用」と呼ばれる。
同様に一時的に排出口側の気圧が下がる現象は、床下配管に接続されている別の排水機器に排水が行われた際にも発生する場合があり、これは「誘導サイホン作用」と呼ばれる。
このような、自己サイホン作用、または誘導サイホン作用が働くと、排水の流れによって排出口側の気圧が下がる一方で、排水口側の気圧は１気圧のまま変化が無い。このため、防臭筒の筒状体内部では封水の水位は気圧差分降下してゆき、水位が防臭筒の下端まで下がると、そこで空気が排水の流れ（防臭筒の下端から、防臭筒と封水部外壁の間の部分の水面迄の間の流れ）に混入して、「ゴボゴボ」といった不快な音を発生させる。
この「ゴボゴボ」という騒音を小さくする方法として、防臭筒の筒状体の排水が流れる部分の開口面積を小さくして、空気が大量に流れないようにする方法があるが、このような方法を採用すると、同時に排水も大量に流れることができなくなり、排水トラップの重要な要素である排水性能が悪化する。
本発明は上記問題点に鑑み発明されたものであって、流し台、洗面台、浴槽・浴室、洗濯機パン等の排水トラップを使用した際、排水を処理する排水性能をあまり悪化させずに、「ゴボゴボ」といった騒音を小さくすることを目的とする。
The sealed water drain trap as described above has the following problems.
In the above-mentioned sealed-type drain trap, when drainage flows into the drain trap by using a sink, the drainage flows by entraining the air in the drainage pipe and the air in the underfloor pipe, so the drainage is completed. There is a case where the pressure on the outlet side temporarily decreases, which is called “self-siphoning”.
Similarly, the phenomenon that the pressure on the outlet side temporarily drops may also occur when drainage is performed to another drainage device connected to the underfloor piping, which is called "guided siphon action". .
When such a self-siphoning action or an induction siphoning action is applied, the pressure on the discharge port side is lowered by the flow of drainage, while the pressure on the drainage port side remains 1 atm. For this reason, the water level of the sealed water drops within the cylindrical body of the deodorizing cylinder, and when the water level drops to the lower end of the deodorizing cylinder, air flows there (from the lower end of the deodorizing cylinder, the Mixing in the flow between the outer walls of the water part up to the water surface), an unpleasant sound such as “gobogobo” is generated.
As a method of reducing this “gobogobo” noise, there is a method of reducing the opening area of the portion where the drainage of the cylindrical body of the deodorizing cylinder flows so that a large amount of air does not flow. If it is adopted, a large amount of drainage cannot flow at the same time, and the drainage performance that is an important element of the drain trap deteriorates.
The present invention was invented in view of the above problems, and when using a drainage trap such as a sink, a washbasin, a bathtub / bathroom, a washing machine pan, etc., without significantly deteriorating the drainage performance of treating drainage, The purpose is to reduce noise such as “gobogobo”.

本発明の排水トラップは、以下の効果を奏する。
請求項１に記載の本発明では、嵌合する部分が封水部よりも上方に配置される、防臭筒に嵌合して防臭筒の排水が流れる部分の開口面積を減少する消音部材を備えたことで、防臭筒の筒状体の内側に覆いを設けたこととなり、騒音が直接防臭筒の筒状体の外側に洩れなくなるため、大きな騒音が発生しにくくなる。
一方で、防臭筒の下方の排水が流れる部分の開口面積が大きいままであるため、単純に防臭筒の筒状体の、排水流路の断面積を小さくした場合より良好な排水性能を得ることができる。
又、排水の通過部分を縦方向の開口とし、更に筒状部の下端に底面を設けたことで、騒音の発生源である防臭筒の筒状部の下端から、直接騒音が排水口に向かうことがなくなり、大きな騒音が発生しにくくなる。
さらに、上記排水トラップの消音部材において、通水部を奇数個設けると共に、該通水部を、筒状部の中心軸を中心として等角度に配置して構成したことから、通水部の（筒状部の中心軸に向かう方向の）対向位置には通水部ではなく、筒状部の壁が配置されることになる。通水部の開口同士が向かい合った位置で配置されると、騒音が共鳴しやすく、騒音がより大きな音となるが、本発明では、通水部の開口の対向位置には壁を設けたため、共鳴が発生し難く、騒音が大きくなりにくい。
請求項２に記載の本発明では、騒音の音波が防臭筒（５）の下端から一直線に排水口（３）に向かうことがなくなり、好適な消音効果を奏すことが出来る。
請求項３に記載の本発明では、通水部（１０）の少なくとも下端が封水部上端（２a）よりも下方に位置する為、排水時の騒音を消音することが出来る。
請求項４に記載の本発明では、上記消音部材の底面の形状を具体的に示すことが出来る。

上記のように構成された排水トラップ配管において、シンク（Ｓ）内に排水が行われると、排水は、排水口（３）、防臭筒（５）の上方の開口から消音部材（４）の筒状部（９）上方の開口、通水部（１０）、防臭筒（５）下端の開口、封水部（２）の上端を介して排出口（４）に至り、最終的には床下配管から下水側等に排出される。
また、このとき封水部（２）に排水が溜まることで、排水トラップ内に形成された排水流路（排水口（３）から排出口（４）に至るまでの排水の流れ路）の少なくとも一部に、封水と呼ばれる排水が溜まって、トラップ機能を生じる。
In the drain trap pipe configured as described above, when drainage is performed in the sink (S), the drainage is performed from the drain port (3) and the opening of the deodorizing cylinder (5) to the cylinder of the sound deadening member (4). It reaches the discharge port (4) through the upper opening of the shape part (9), the water passing part (10), the opening at the lower end of the deodorizing cylinder (5), the upper end of the water sealing part (2), and finally the underfloor piping To the sewage side.
At this time, at least the drainage flow path (drainage flow path from the drainage port (3) to the drainage port (4)) formed in the drainage trap is formed by the accumulation of drainage in the sealed water portion (2). In some cases, wastewater called sealed water accumulates, which causes a trap function.
更に本実施例では、嵌合する部分が封水部（２）よりも上方に配置される、防臭筒（５）に嵌合して防臭筒（５）の開口面積を減少する消音部材（７）を備えたことで、防臭筒（５）の筒状体（６）の内側に覆いを設けたこととなり、騒音が直接防臭筒（５）の筒状体（６）の外側に洩れなくなるため、従来の封水式排水トラップに比べて大きな騒音が発生しにくくなる。
一方で、防臭筒（５）の下方の排水が流れる部分の開口面積（防臭筒（５）の筒状体（６）の下端の開口面積）は大きいままであるため、排水性能は、防臭筒（５）の筒状体（６）の排水が流れる部分の開口面積を、消音部材（７）の筒状部（９）の排水が流れる部分の開口面積と同じとなるように寸法設計した従来例と比べて良好である（もちろん排水の入り口に当たる筒状部（９）の上端の、排水が流れる部分の開口面積は、防臭筒（５）の筒状体（６）上端の、排水が流れる部分の開口面積より小さくなっているため、各部寸法が上記実施例と全く同じで、消音部材（７）のみ省略したような排水トラップと比べれば排水性能は悪化する）。
また、上記実施例の消音部材（７）では、排水の通過部分を縦方向の開口とし、更に筒状部（９）の下端に底面を設けたことで、騒音の発生源である防臭筒（５）の下端から一直線に直接騒音が排水口（３）に向かうことがなくなる。騒音の音波は、防臭筒（５）内を反射するか、又は壁面を介して排水口（３）に到達するようになるため、その分音のエネルギーが減少し、排水口（３）に開放される騒音量を減じることができた。
更に、上記消音部材（７）は通水部（１０）を奇数個、この実施例では３個設けると共に、該通水部（１０）を、平面視筒状部（９）の中心軸を中心として平面視等角度（この実施例では１２０度毎）に配置し、その対向位置には他の通水部（１０）ではなく、筒状部（９）の壁面が配置されるように構成して成る。
通水部（１０）の開口同士が向かい合った位置で配置されると、騒音が共鳴しやすく、騒音がより大きな音となるが、本発明では、通水部（１０）の開口の対向位置には壁を設けたため、共鳴が起こらず、騒音が大きくなりにくい。
Further, in the present embodiment, the sound absorbing member (7) which fits the deodorizing cylinder (5) and reduces the opening area of the deodorizing cylinder (5), the fitting portion being disposed above the sealing portion (2). ), A cover is provided on the inside of the cylindrical body (6) of the deodorizing cylinder (5), and noise does not leak directly to the outside of the cylindrical body (6) of the deodorizing cylinder (5). In comparison with the conventional sealed drain trap, it is difficult to generate a large noise.
On the other hand, since the opening area (the opening area at the lower end of the cylindrical body (6) of the deodorizing cylinder (5)) where the drainage flows below the deodorizing cylinder (5) remains large, the drainage performance is Conventionally, the opening area of the portion where the drainage of the cylindrical body (6) of (5) flows is the same as the opening area of the portion of the cylindrical portion (9) where the drainage flows of the silencer member (7). It is better than the example (of course, the opening area of the upper part of the cylindrical part (9) that hits the inlet of the drainage, where the drainage flows, the drainage flows at the upper end of the cylindrical body (6) of the deodorizing cylinder (5) Since it is smaller than the opening area of the part, the dimensions of each part are exactly the same as in the above embodiment, and the drainage performance is deteriorated as compared with a drain trap in which only the silencing member (7) is omitted.
Moreover, in the muffling member (7) of the said Example, the passage part of drainage was made into the opening of a vertical direction, and also the bottom part was provided in the lower end of the cylindrical part (9), and the deodorizing cylinder ( Noise does not go directly to the drain (3) in a straight line from the lower end of 5). The sound wave of noise reflects inside the deodorizing cylinder (5) or reaches the drain (3) through the wall surface, so the energy of the sound is reduced and opened to the drain (3). Was able to reduce the amount of noise.
Further, the silencing member (7) is provided with an odd number of water passage portions (10), three in this embodiment, and the water passage portion (10) is centered on the central axis of the cylindrical portion (9) in plan view. Are arranged at equal angles in plan view (every 120 degrees in this embodiment), and the wall of the cylindrical portion (9) is arranged at the opposite position instead of the other water flow portion (10). It consists of
When the openings of the water flow section (10) are arranged at positions facing each other, noise is likely to resonate and the noise becomes louder. However, in the present invention, the openings are located at positions opposite to the openings of the water flow section (10). Since a wall is provided, resonance does not occur and noise is difficult to increase.
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、発明の要旨を変更しない範囲で、自在に変更が可能である。
例えば、上記実施例では、流し台（Ｎ）の排水トラップに本発明の構成を採用しているが、本発明は上記実施例に限定されることなく、例えば図６に示したように、浴槽用トラップに、本発明の構成を採用しても構わない。
The embodiment of the present invention is as described above, but the present invention is not limited to the above embodiment, and can be freely changed without departing from the scope of the invention.
For example, in the said Example, although the structure of this invention is employ | adopted for the drain trap of a sink (N), this invention is not limited to the said Example, For example, as shown in FIG. You may employ | adopt the structure of this invention for a trap.
また、上記実施例では、封水部（２）から溢れた排水は、直接排出口（４）に流れ出る構成となっているが、図６に示した排水トラップのように、封水部（２）の周囲に排水の溢れ流路（１５）を設け、該溢れ流路の側面に排出口（４）を設けてもよい。このように封水部（２）と排出口（４）の間に溢れ流路（１５）を設けた排水トラップは、一度に封水部（２）を溢れ出ることのできる排水の量が増加するため、排水性能を向上することができるが、その分サイホン作用による負圧の影響を受けやすく、騒音が発生しやすい。このため、本発明の消音部材（７）を採用すると、効果的に騒音を減少させ、好適な排水トラップとすることができる。 Moreover, in the said Example, although the waste_water | drain overflowing from the sealing part (2) flows out directly to the discharge port (4), like the drain trap shown in FIG. 6, the sealing part (2 ) May be provided with a drainage overflow channel (15), and a discharge port (4) may be provided on a side surface of the overflow channel. Thus, the drain trap which provided the overflow channel (15) between the sealed water part (2) and the discharge port (4) increases the amount of drainage that can overflow the sealed water part (2) at a time. Therefore, although drainage performance can be improved, it is easily affected by negative pressure due to siphon action, and noise is likely to be generated. For this reason, when the silencing member (7) of the present invention is employed, noise can be effectively reduced and a suitable drain trap can be obtained.
また、図６の実施例では、排水性能を優先させるために、通水部（１０）の幅より筒状部（９）の壁面の幅のほうが若干幅狭になるように構成されてなるが、共鳴防止の効果をより効果的に発生させるため、通水部（１０）の幅より筒状部（９）の壁面の幅のほうが若干幅広になるように構成しても良い。 Further, in the embodiment of FIG. 6, in order to give priority to the drainage performance, the wall surface of the tubular portion (9) is configured to be slightly narrower than the width of the water flow portion (10). In order to generate the effect of preventing resonance more effectively, the width of the wall surface of the tubular portion (9) may be slightly wider than the width of the water flow portion (10).
また、図１乃至図５の実施例、また図６の実施例では、排出口（４）を側面方向に設けているが、図７に示した実施例のように、排水口（３）を排水トラップの底面に設けて構成しても良い。 Further, in the embodiment of FIGS. 1 to 5 and the embodiment of FIG. 6, the discharge port (4) is provided in the side surface direction, but the drain port (3) is provided as in the embodiment shown in FIG. You may comprise by providing in the bottom face of a drain trap.
