Description

本発明は、洗面器等に使用するS型或いはP型トラップ(以下、トラップにて代表する)において破封しにくい構造のトラップを提供するものである。   The present invention provides a trap having a structure that is difficult to break in an S-type or P-type trap (hereinafter referred to as a trap) used in a washbasin or the like.

従来より、トラップの封水切れに関しては、封水深さの他に、流入側管の断面積と流出側管の断面積の比率である脚断面比の影響が大いと言われており、具体的にはトラップにおける流入側管の断面積を流出側管の断面積より大きくすることにより、封水が切れ難いことは分かっている。ユニットバスや洗濯機用のトラップであれば、構造上の関係から断面積を調整することによって封水に対して切れにくい構造とすることが可能であった。   Conventionally, it has been said that in addition to the sealing water depth, the trap cross-section ratio is largely influenced by the cross-sectional area of the inflow side pipe and the cross-sectional area of the outflow side pipe. It is known that sealing water is hard to break by making the cross-sectional area of the inflow side pipe in the trap larger than the cross-sectional area of the outflow side pipe. In the case of a trap for a unit bath or a washing machine, it was possible to make a structure that is difficult to cut against sealed water by adjusting the cross-sectional area from the structural relationship.

図1はS型トラップの周知形状を示すものであり、封水部aに対し、排水の流入側管bと排水の流出側管cとの管の径は同一の径とされているのが一般的である。図示したように、洗面器等で用いられるトラップは、20〜40mm径の管が流入側から流出側まで同一径で、屈折する形で形成されているため、単純にその断面積を調整することが不可能であった。又、排水の大前提である固形物の詰まりの観点から、管の途中で細くしないことが大原則であり、封水切れに対して強いトラップを作ることが困難であった。   FIG. 1 shows a well-known shape of the S-type trap, and the diameter of the drainage inflow side pipe b and the drainage outflow side pipe c is the same diameter with respect to the sealed part a. It is common. As shown in the figure, the trap used in a wash basin etc. is formed with a 20-40 mm diameter tube with the same diameter and refracting from the inflow side to the outflow side, so simply adjust its cross-sectional area. Was impossible. In addition, from the viewpoint of clogging of solid matter, which is a major premise of drainage, it is a general principle not to make it thin in the middle of the pipe, and it has been difficult to make a strong trap against running out of sealed water.

本発明は、以上の従来技術に鑑みてなされたものであり、洗面器等に使用する破封しにくい構造のトラップを提供するものである。   This invention is made | formed in view of the above prior art, and provides the trap of the structure which is hard to tear used for a washbasin etc.

本発明の要旨(請求項1)は、洗面器等に使用するS型或いはP型トラップであって、封水形成部位に至るまで流入側管の断面積を分割し、夫々の断面積が流出側管の断面積よりも小さくし、固形物の詰まりを防止したことを特徴とする排水トラップにかかるものである。   The gist of the present invention (Claim 1) is an S-type or P-type trap used in a basin or the like, and divides the cross-sectional area of the inflow side tube up to the sealed water formation site, and each cross-sectional area flows out. The drainage trap is characterized in that it is smaller than the cross-sectional area of the side pipe and prevents clogging of solid matter.

具体的には、流入側管の断面積の合計が流出側管の断面積よりも大きくした構成であり、簡便な構成としては、トラップの流入側管に流入口を複数に分割する分流部材を嵌め込んだ(請求項2)トラップである Specifically, the total cross-sectional area of the inlet-side pipe is a configuration that is larger than the cross-sectional area of the outlet-side pipe, as the simple construction, branch stream is divided into a plurality of inlets on the inflow side pipe of the trap The trap is fitted with a member (claim 2) .

本発明は以上の構成を採用したものであり、請求項1のようにトラップにおける流入側管の断面積と流出側管の断面積を特定することにより破封防止トラップが得られたものであり、これを具現化するために請求項の分流部材を流入側管に嵌め込めばよいものである。 The present invention employs the above-described configuration, and the anti-seal trap is obtained by specifying the cross-sectional area of the inflow side pipe and the cross-sectional area of the outflow side pipe in the trap as in claim 1 . In order to realize this, the flow dividing member according to claim 2 may be fitted into the inflow side pipe.

本発明(請求項1及び請求項2)は、排水の流入側の管に関しては管内部を分割したものであり、流入側全体の断面積は大きくしたが、分割された管の断面積は、夫々流出側管の断面積よりも小さくすることによって、途中で管径を細くしない構成としたもので、これによって固形物の詰まりの問題も解決された上に、流入側管全体の断面積/流出側管の断面積で定義される脚断面積比を大きくして、封水が切れにくい構造のトラップとしたものである。尚、排水の流入側の管内部を分割したもので、かかる分割部位は封水部分に達する深さとする必要がある。   In the present invention (Claim 1 and Claim 2), the inside of the pipe is divided with respect to the pipe on the inflow side of drainage, and the cross-sectional area of the entire inflow side is enlarged, but the cross-sectional area of the divided pipe is By making each smaller than the cross-sectional area of the outflow side tube, the tube diameter is not reduced in the middle. This solves the problem of clogging of solid matter, and the cross-sectional area of the entire inflow side tube / The leg cross-sectional area ratio defined by the cross-sectional area of the outflow side pipe is increased to form a trap having a structure in which the sealed water is not easily cut off. In addition, it is what divided | segmented the pipe | tube inside at the inflow side of waste_water | drain, and this division | segmentation site | part needs to be the depth which reaches a sealing part.

流入側管の分割は何分割でもよいが、通常は2〜4分割程度で流入側が32〜40mm径程度が妥当である。一般的な洗面器の排水口には十字の固形物転落防止用の棒がついているため、それに合わせた形状で開口部から4分割で連続している形態が最も好ましい。請求項3において、分流部材の例としては、断面十字形状の分流部材を管内に嵌め込むだけで十分である。尚、ヘア−キャッチャ−受けの裏側に十字形の突起を形成する例がある(特許文献1)がこれは単なる補強であって、かかる十字形状が封水形成部位に至るまで伸びてはおらず、本発明のものとは基本的に異なるものである。   The inflow side pipe may be divided into any number of parts, but usually about 2 to 4 parts, and a diameter of about 32 to 40 mm on the inflow side is appropriate. Since the drain of a general wash basin is provided with a cross-shaped stick for preventing the falling of solid matter, a form corresponding to that and continuous from the opening in four parts is most preferable. In claim 3, as an example of the flow dividing member, it is sufficient to fit the flow dividing member having a cross-shaped cross section into the pipe. In addition, there is an example in which a cross-shaped protrusion is formed on the back side of the hair-catcher-receiver (Patent Document 1), but this is merely reinforcement, and such a cross-shaped shape does not extend to the sealed water formation site, It is fundamentally different from that of the present invention.

図2は本発明のS型破封防止トラップの図であり、封水部1に対し排水の流出側管3の径は同一の径とされている。排水の流入側管2は洗面器4の排水口に接続され、封水部1に連なる排水流入部である。この排水流入部は少なくとも封水部1に至るまでの深さを有するものである。従来より用いられている勾配排水の場合は、排水の流出側管3と封水部1の径は20〜40mm程度であり、流入側管2の径は32〜50mm程度である。尚、サイフォン排水の場合にあっては、排水の流出側管3と封水部1の径は20〜25mm程度である。   FIG. 2 is a diagram of an S-type anti-seal break trap according to the present invention. The diameter of the drainage outlet pipe 3 is the same as that of the sealed part 1. The drainage inflow side pipe 2 is connected to the drainage port of the basin 4, and is a drainage inflow part connected to the sealing part 1. The drainage inflow portion has a depth that reaches at least the sealed water portion 1. In the case of the gradient drainage conventionally used, the diameter of the drainage outflow side pipe 3 and the sealed water part 1 is about 20 to 40 mm, and the diameter of the inflow side pipe 2 is about 32 to 50 mm. In the case of siphon drainage, the diameters of the drainage outflow side pipe 3 and the sealing part 1 are about 20 to 25 mm.

そして、流入側管2内には図3に示すようにフィン11を断面十字形状に形成した分流部材10を嵌め込んだものであり、好ましくは、基本的にこの分流部材10にて分割された部位は夫々独立しているものである。   In the inflow side pipe 2, as shown in FIG. 3, a flow dividing member 10 in which fins 11 are formed in a cross-shaped cross section is fitted. Preferably, the flow dividing member 10 is basically divided by the flow dividing member 10. Each part is independent.

この実施例にあって、脚断面積比は1.0以上であり、排水流入側管は全体として排水流出側管よりも径を大きくすることで破封防止性能を向上させたものであり、一方、排水流入側管に分流部材によって形成された各流入管は排水流出側管よりも夫々の断面積が小さく構成されたものであり、逆に言えば、排水流出側管は排水流入側管よりも径が大きいことから固形物の詰まりに対しても対応できることとなったものである。   In this embodiment, the leg cross-sectional area ratio is 1.0 or more, and the drainage inflow side pipe as a whole has an improved sealing prevention performance by making the diameter larger than the drainage outflow side pipe. On the other hand, each inflow pipe formed by the diversion member on the drainage inflow side pipe has a smaller sectional area than the drainage outflow side pipe. Conversely, the drainage outflow side pipe is a drainage inflow side pipe. Since the diameter is larger than this, it can cope with clogging of solid matter.

図4及び図5は本発明に用いられる分流部材の別例であり、図4はフィン11を120度方向に形成した分流部材10であり、流入側管の内部を3分割する。一方、図5はフィン11を180度に形成し、補助フィン12を備えて管内に支持し、流入側管の内部を2分割する分流部材の例である。勿論、分流部材の形状はこれに限定されるものではなく、夫々のフィンによって分割された流入側の断面積が流出側の断面積よりも小さいことが条件である。   4 and 5 show another example of the flow dividing member used in the present invention. FIG. 4 shows the flow dividing member 10 in which the fins 11 are formed in the direction of 120 degrees, and divides the inside of the inflow side pipe into three parts. On the other hand, FIG. 5 shows an example of a flow dividing member in which the fin 11 is formed at 180 degrees, the auxiliary fin 12 is provided and supported in the pipe, and the inside of the inflow side pipe is divided into two. Of course, the shape of the flow dividing member is not limited to this, and the condition is that the cross-sectional area on the inflow side divided by the respective fins is smaller than the cross-sectional area on the outflow side.

図6は本発明に用いられる分流部材の参考例であり、メインの排水流路に対してバイパス流路10aを形成して目的を達成するものである。 FIG. 6 is a reference example of the flow dividing member used in the present invention, and achieves the object by forming a bypass flow path 10a with respect to the main drain flow path.

本発明は主として洗面器のS型トラップをもって説明したが、P型トラップについても適用できるものであり、更には、洗面器以外の水周り器具のトラップにも広く採用可能である。   Although the present invention has been described mainly with the S-type trap of the basin, the present invention can also be applied to the P-type trap, and can be widely applied to traps for water-related devices other than the basin.
