Description

本発明は、排水機器にて生じた排水を、下水側に排出する排水配管に関するものである。   The present invention relates to a drainage pipe for discharging wastewater generated by drainage equipment to the sewage side.

従来より、洗面台、流し台、浴室、洗濯機など、使用によって排水が生じる機器(以下「排水機器」という)の、使用によって生じた排水を下水側に排出処理するため、排水配管が施工される。排水配管の施工の様態は様々であるが、図1に示した排水配管などがその一例として上げられる。
図1に示した排水配管は、排水機器である洗面台に備えられる排水配管であって、管体の途中に管体をUの字に屈曲させた屈曲部分を設け、この屈曲部分に封水と呼ばれる排水の溜まり部分を設けて、臭気や害虫類の逆流を防止する、封水式の排水トラップを備えてなる。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, drainage pipes are constructed to discharge wastewater generated by use to the sewage side of equipment that generates wastewater (hereinafter referred to as “drainage equipment”), such as washstands, sinks, bathrooms, and washing machines. . The manner of construction of drainage pipes is various, but the drainage pipes shown in FIG.
The drainage pipe shown in FIG. 1 is a drainage pipe provided in a wash basin that is a drainage device, and is provided with a bent portion obtained by bending the pipe body into a U-shape in the middle of the pipe body, and the bent portion is sealed with water. It is equipped with a sealed drainage trap that prevents the backflow of odors and pests by providing a drainage reservoir called sewage. A well-known sealed drainage trap will be described below with reference to the drawings.

図1に示した排水配管は、洗面台の洗面ボウルに接続された、排水トラップ含む排水配管であって、排水栓、排水管、トラップ部材、等より構成されてなる。
排水栓は、上方に排水が流入する排水口を備えた略円筒形状の部材であって、洗面ボウル底面の貫通孔に取り付けられる。
トラップ部材は管体をU字形状に屈曲させた部材であって、施工完了時、U字の屈曲部分が下方に配置される。排水機器を使用し、その内部に排水が流れると、この屈曲部分に排水が流れて、「封水」と呼ばれる排水の溜まり部分を形成する。この封水によって下水側から臭気や害虫類が屋内側に侵入することを防止することができる。このような、下水側から臭気や害虫類が屋内側に侵入することを防止する機能を「トラップ機能」と呼ぶ。
排水管は略円筒形状の部材であって、上記排水栓とトラップ部材、トラップ部材と下水側配管を接続している。これらの排水管には直線的な構造のものの他に、必要に応じて屈曲した管体が使用される。
尚、これら排水配管は、樹脂材であるポリプロピレンによって構成される。
これらの排水配管が接続される洗面台は、上方に槽体である洗面ボウルが備えらた箱体の排水機器であって、該洗面ボウルの底面には排水栓が接続される貫通孔が設けられてなる。
The drain pipe shown in FIG. 1 is a drain pipe including a drain trap connected to a wash bowl of a wash basin, and is constituted by a drain plug, a drain pipe, a trap member, and the like.
The drain plug is a substantially cylindrical member provided with a drain port through which drainage flows upward, and is attached to the through-hole on the bottom surface of the wash bowl.
The trap member is a member obtained by bending a tubular body into a U-shape, and when the construction is completed, a U-shaped bent portion is disposed below. When drainage equipment is used and drainage flows through it, the drainage flows through this bent portion to form a drainage reservoir called “sealed water”. This sealing water can prevent odors and pests from entering the indoor side from the sewage side. Such a function of preventing odors and pests from entering the indoor side from the sewage side is called a “trap function”.
The drain pipe is a substantially cylindrical member, and connects the drain plug and the trap member, and the trap member and the sewage side pipe. In addition to the straight structure, these drain pipes use bent pipes as necessary.
These drain pipes are made of polypropylene, which is a resin material.
The wash basin to which these drainage pipes are connected is a box drainage device provided with a wash bowl that is a tank body above, and a through hole to which a drain plug is connected is provided on the bottom surface of the wash bowl. It will be.

上記排水配管は、以下のようにして洗面台の洗面ボウルに接続される
洗面ボウルの排水口に排水栓を接続して固定する。更に排水栓とトラップ部材を、排水管を介して接続し、更に排水管の下流側端部と床下の下水側配管を接続して、洗面ボウルへの、排水配管の接続が完了する。
The drainage pipe is fixed by connecting a drain plug to the drainage port of the wash bowl connected to the wash bowl of the wash stand as follows. Further, the drain plug and the trap member are connected via the drain pipe, and further, the downstream end of the drain pipe and the sewage side pipe below the floor are connected, and the connection of the drain pipe to the wash bowl is completed.

上記のように構成した排水配管において洗面ボウル内に排水が生じると排水は排水栓の排水口から排水管を介してトラップ部材内に流入し、トラップ部材内で封水を形成した上で、下流側の排水管を通過し、下水側に排出される。   When drainage occurs in the wash bowl in the drainage pipe configured as described above, the drainage flows into the trap member from the drain outlet of the drain plug through the drain pipe, forms a sealed water in the trap member, and then downstream It passes through the side drain pipe and is discharged to the sewage side.

上記のような排水配管において生じる問題として、排水配管の管詰まりという問題がある。排水配管を流れる排水は、洗面台、流し台、浴室、洗濯機など、例えば洗浄や洗濯などに使用された水であるため、その中には塵芥や厨芥、油分などが混入している。排水配管には下流側に向かって少なくとも通常1/50の下り勾配(水平方向に50単位進むとき、垂直方向に1単位下降する勾配)が設けられているが、排水が終了段階になると、表面張力によって生じる、水滴が排水配管を構成する樹脂表面に付着しようとする力が、勾配によって下流側に排水を流そうとする力よりも大きくなってしまい、排水配管内面に水滴が付着し留まった状態となる。この状態から水滴が乾燥して水分が除かれると、水滴中に有った塵芥や厨芥、油分が排水配管の内面に固着した状態となる。これを繰り返すうちに、管の内壁にこれらが付着・堆積して管内部を閉塞し、排水の流れを封じてしまう、という問題がある。
また、上記したように排水配管には、臭気や害虫類の逆流を防止するトラップ部材が配置される。排水の流れる勢いは、このトラップ部材の部分で減速するため、この部分で塵芥や厨芥が付着したり、排水の勢いが弱くなり、排水に押し流されることなく堆積して管詰まりが生じる場合がある。このように管詰まりが生じた場合、排水配管を分解して管詰まりを直接取り除くか、あるいは洗浄水を高圧で放出して管詰まりを吹き飛ばす、高圧洗浄器の使用などによって、管詰まりを解消することができる。しかしながら、これらの方法は手間や機材の準備など多大な労力を要するし、作業が行われるまでは当然管詰まりの問題が存在したままとなるなど、あくまでも管詰まりが生じてから行う措置に過ぎず、管詰まりを生じさせない、というものではなかった。
As a problem that occurs in the drainage pipe as described above, there is a problem that the drainage pipe is clogged. Since the drainage flowing through the drainage pipe is water used for washing, washing, etc., such as a wash basin, a sink, a bathroom, a washing machine, etc., dust, soot, oil, etc. are mixed therein. The drainage pipe is provided with a downward slope of at least 1/50 normally toward the downstream side (a slope that descends by 1 unit in the vertical direction when it proceeds 50 units in the horizontal direction). The force caused by the tension that causes the water droplets to adhere to the resin surface constituting the drainage pipe is greater than the force that causes the drainage to flow downstream due to the gradient, and the waterdrops remain attached to the inner surface of the drainage pipe. It becomes a state. When the water droplets are dried and moisture is removed from this state, the dust, soot, and oil contained in the water droplets are fixed to the inner surface of the drain pipe. As this process is repeated, there is a problem that these adhere to and accumulate on the inner wall of the pipe, block the inside of the pipe, and seal the flow of drainage.
In addition, as described above, the drain pipe is provided with a trap member that prevents backflow of odors and pests. Since the momentum of the drainage flow is reduced at this trap member, dust and soot may adhere to this part, or the momentum of the drainage may weaken and accumulate without being swept away by the drainage, resulting in tube clogging. . If such clogging occurs, resolve the clogging by disassembling the drainage pipe and removing the clogging directly, or by discharging the washing water at a high pressure to blow the clogging or using a high-pressure washer. be able to. However, these methods require a lot of labor such as labor and preparation of equipment, and the problem of tube clogging naturally remains until the work is carried out. It did not mean that it would not cause tube clogging.

本発明は上記の課題に鑑みて成されたものであって、排水機器に施行される排水配管において、管詰まりの発生を防止する排水配管に関するものである。   This invention is made in view of said subject, Comprising: In the drainage piping enforced by drainage equipment, it is related with the drainage piping which prevents generation | occurrence | production of pipe | tube clogging.

請求項1に記載の本発明は、排水機器にて生じた排水を、下水側に排出する排水配管において、樹脂又は金属製の排水配管の内面に、排水と排水配管内面との摩擦係数を減じる潤滑コーティングを施したことを特徴とする、排水配管である。   The present invention according to claim 1 reduces the friction coefficient between the drainage and the inner surface of the drainage pipe on the inner surface of the resin or metal drainage pipe in the drainage pipe that discharges the drainage generated in the drainage device to the sewage side. The drainage pipe is characterized by having a lubricating coating.

請求項2に記載の本発明は、上記排水配管において、排水配管中に臭気や害虫類の逆流を防止する、排水トラップを備えたことを特徴とする、段落0009に記載の撹拌装置である。   The present invention described in claim 2 is the agitation apparatus according to paragraph 0009, wherein the drainage pipe is provided with a drainage trap that prevents backflow of odors and pests in the drainage pipe.

請求項3に記載の本発明は、上記排水配管において、排水トラップが、配管の途中に封水と呼ばれる、排水の溜まり部分を設けて臭気や害虫類の逆流を防止する、封水式トラップであることを特徴とする、段落0010に記載の排水配管である。   The present invention according to claim 3 is a sealed trap in which the drain trap is provided with a reservoir portion of drainage in the middle of the pipe to prevent backflow of odors and pests. The drainage pipe according to paragraph 0010, characterized by being.

請求項4に記載の本発明は、上記排水配管において、上記潤滑コーティングを撥水コーティングとしたことを特徴とする、段落0009乃至段落0011のいずれか1つに記載の撹拌装置である。   The present invention described in claim 4 is the stirring device according to any one of paragraphs 0009 to 0011, wherein in the drainage pipe, the lubricating coating is a water repellent coating.

本発明の撹拌装置は、以下の効果を奏する。
請求項1に記載した本発明では、樹脂製又は金属製の排水配管の内面に、潤滑コーティングを施したことによって、潤滑コーティングを施さない排水配管に比べ、排水配管の内面に水滴が留まることが殆ど無くなる。このため、従来の排水配管のように、水滴中に有った塵芥や厨芥、油分が水滴の蒸発によって排水配管の内面に固着した状態となることがなく、管詰まりの発生を防止することができる。また排水の減速要素である排水管内面と排水の間に生じる、表面張力による減速が潤滑コーティングによって減少するため、排水の流れる速度が低下し、管詰まりが生じやすくなる排水トラップのトラップ部材内部、特に封水を採用した封水式排水トラップのトラップ部材内部に採用すると管詰まりが防止でき好適である。
また、排水配管内部に施す潤滑コーティング加工の一例として、請求項4に記載したように、排水の接触それ自体を防止することで、摩擦係数を下げる、撥水コーティングが考えられる。
The stirring device of the present invention has the following effects.
In the present invention described in claim 1, since the lubrication coating is applied to the inner surface of the resin or metal drainage pipe, water droplets may remain on the inner surface of the drainage pipe compared to the drainage pipe not provided with the lubrication coating. Almost disappear. For this reason, unlike conventional drainage pipes, dust, soot, and oil in the waterdrops are not fixed to the inner surface of the drainage pipes due to evaporation of the waterdrops, preventing clogging. it can. Also, since the deceleration due to surface tension that occurs between the drain pipe inner surface and the drainage, which is the draining element of the drainage, is reduced by the lubrication coating, the drainage flow speed decreases, and the inside of the trap member of the drain trap where pipe clogging is likely to occur, In particular, when it is adopted inside the trap member of a sealed drainage trap that employs sealed water, it is preferable because it can prevent clogging.
Further, as an example of the lubrication coating process applied to the inside of the drain pipe, a water repellent coating that lowers the coefficient of friction by preventing contact of the drain itself can be considered as described in claim 4.

以下に本発明の実施例を、図面を参照しつつ説明する。
図1示した本発明の排水配管は、洗面台の洗面ボウルに接続された、排水トラップ含む排水配管であって、排水栓、排水管、トラップ部材、等より構成されてなる。
排水栓は、上方に排水が流入する排水口を備えた略円筒形状の部材であって、洗面ボウル底面の貫通孔に取り付けられる。
トラップ部材は管体をU字形状に屈曲させた部材であって、施工完了時、U字の屈曲部分が下方に配置される。排水機器を使用し、その内部に排水が流れると、この屈曲部分に排水が流れて、「封水」と呼ばれる排水の溜まり部分を形成する。この封水によって下水側から臭気や害虫類が屋内側に侵入することを防止することができる。このような、下水側から臭気や害虫類が屋内側に侵入することを防止する機能を「トラップ機能」と呼び、サナに封水によってトラップ機能を得るようにした排水トラップを封水式排水トラップと呼ぶ。
排水管は略円筒形状の部材であって、上記排水栓とトラップ部材、トラップ部材と下水側配管を接続している。これらの排水管には直線的な構造のものの他に、必要に応じて屈曲した管体が使用される。
尚、これら排水配管は、樹脂材であるポリプロピレンによって構成される。
更にこれら排水配管の内面には撥水性を向上させるコーティングが施されている。この撥水コーティングにより、内部を流れる排水と排水配管内面とが殆ど接触しなくなるため、排水と排水配管内面との摩擦係数が、撥水コーティングを施していない場合に比べ大幅に減少している。
これらの排水配管が接続される洗面台は、上方に槽体である洗面ボウルが備えらた箱体の排水機器であって、該洗面ボウルの底面には排水栓が接続される貫通孔が設けられてなる。
Embodiments of the present invention will be described below with reference to the drawings.
The drain pipe of the present invention shown in FIG. 1 is a drain pipe including a drain trap connected to a wash bowl of a wash basin, and includes a drain plug, a drain pipe, a trap member, and the like.
The drain plug is a substantially cylindrical member provided with a drain port through which drainage flows upward, and is attached to the through-hole on the bottom surface of the wash bowl.
The trap member is a member obtained by bending a tubular body into a U-shape, and when the construction is completed, a U-shaped bent portion is disposed below. When drainage equipment is used and drainage flows through it, the drainage flows through this bent portion to form a drainage pool called “sealed water”. This sealing water can prevent odors and pests from entering the indoor side from the sewage side. Such a function that prevents odors and pests from entering the indoor side from the sewage side is called the "trap function". Call it.
The drain pipe is a substantially cylindrical member, and connects the drain plug and the trap member, and the trap member and the sewage side pipe. In addition to a straight structure, these drain pipes are bent pipes as necessary.
These drain pipes are made of polypropylene, which is a resin material.
Furthermore, the coating which improves water repellency is given to the inner surface of these drain piping. With this water-repellent coating, the drainage flowing inside and the inner surface of the drainage pipe are hardly in contact with each other, so that the friction coefficient between the drainage and the inner surface of the drainage pipe is greatly reduced as compared with the case where the water-repellent coating is not applied.
The wash basin to which these drainage pipes are connected is a box drainage device provided with a wash bowl that is a tank body above, and a through hole to which a drain plug is connected is provided on the bottom surface of the wash bowl. It will be.

上記排水配管は、以下のようにして洗面台の洗面ボウルに接続される
洗面ボウルの排水口に排水栓を接続して固定する。更に排水栓とトラップ部材を、排水管を介して接続し、更に排水管の下流側端部と床下の下水側配管を接続して、洗面ボウルへの、排水配管の接続が完了する。
The drainage pipe is fixed by connecting a drain plug to the drainage port of the wash bowl connected to the wash bowl of the wash stand as follows. Further, the drain plug and the trap member are connected via the drain pipe, and further, the downstream end of the drain pipe and the sewage side pipe below the floor are connected, and the connection of the drain pipe to the wash bowl is completed.

上記のように構成した排水配管において洗面ボウル内に排水が生じると排水は排水栓の排水口から排水管を介してトラップ部材内に流入し、トラップ部材内で封水を形成した上で、下流側の排水管を通過し、下水側に排出される。   When drainage occurs in the wash bowl in the drainage pipe configured as described above, the drainage flows into the trap member from the drain outlet of the drain plug through the drain pipe, forms a sealed water in the trap member, and then downstream It passes through the side drain pipe and is discharged to the sewage side.

更に上記発明では、段落0014に記載したように、樹脂製の排水配管の内面に潤滑コーティングとして撥水コーティングを施したことによって、撥水コーティングを施さない排水配管に比べ、排水配管の内面に水滴が留まることが殆ど無くなる。このため、従来の排水配管のように、水滴中に有った塵芥や厨芥、油分が水滴の蒸発によって排水配管の内面に固着した状態となることがなく、管詰まりの発生を防止することができる。また排水の減速要素である排水管内面と排水の間に生じる、表面張力による減速が撥水コーティングによって減少するため、上昇の際に排水の勢いが減じるU字形状に管体を屈曲させた構造の封水式排水トラップにおいて、撥水コーティングを行わない従来の封水式排水トラップと比べて排水の流れる速度が向上し、トラップ部材内部に付着・堆積しやすい塵芥や厨芥等の汚物を吹き飛ばすように流すことができ、管詰まりが生じにくい。   Furthermore, in the above invention, as described in paragraph 0014, the water-repellent coating is applied to the inner surface of the resin drainage pipe as a lubricating coating, so that water droplets are formed on the inner surface of the drainage pipe compared to the drainage pipe without the water-repellent coating. Will almost never stay. For this reason, unlike conventional drainage pipes, dust, soot, and oil in the waterdrops are not fixed to the inner surface of the drainage pipes due to evaporation of the waterdrops, preventing clogging. it can. Also, because the water repellent coating reduces the deceleration caused by the surface tension between the drain pipe inner surface, which is the drain deceleration element, and the drainage, the pipe is bent into a U-shape that reduces the momentum of the drain when rising. Compared with conventional sealed drainage traps that do not have a water-repellent coating, the sealed drainage traps of this type will improve the flow rate of drainage, and blow away dirt and soot that tends to adhere and accumulate inside the trap members. The tube is less likely to clog.

以上、本発明の主要な実施の形態について説明したが、本発明はこれらの実施の形態に限定されるものではなく、発明の目的を達成でき且つ発明の要旨を逸脱しない範囲内で種々の設計変更が可能である。
例えば上記実施例に示した本発明では、排水配管は樹脂材であるポリプロピレンによって構成されているがこれに代えて金属材、例えばステンレスや真鍮材から構成しても、その内面に潤滑コーティングを施すことで上記実施例と同じ効果を得ることができる。
As mentioned above, although main embodiment of this invention was described, this invention is not limited to these embodiment, Various design is possible within the range which can achieve the objective of invention and does not deviate from the summary of invention. It can be changed.
For example, in the present invention shown in the above embodiment, the drainage pipe is made of polypropylene which is a resin material. Instead, even if it is made of a metal material such as stainless steel or brass material, a lubrication coating is applied to the inner surface thereof. Thus, the same effect as in the above embodiment can be obtained.

また、排水配管も洗面台に用いられる洗面ボウルに施される排水配管に限定することなく、例えば流し台や浴室、または洗濯機などの排水配管に採用することができる。また排水口から下水側の排水を行う排水配管に限定されることなく、例えば槽体に溜まった水が槽体の上縁から溢れないようにするために設けられるオーバーフロー配管等の排水配管に本発明を採用しても構わない。   Further, the drain pipe is not limited to the drain pipe provided to the wash bowl used for the wash basin, and can be employed for drain pipes such as a sink, a bathroom, or a washing machine. Also, it is not limited to drain pipes for draining the sewage side from the drain port. For example, the drain pipe such as an overflow pipe provided to prevent the water accumulated in the tank body from overflowing from the upper edge of the tank body. The invention may be adopted.

また、潤滑コーティングの種類も、上記実施例のように撥水コーティングに限定されるものではなく、排水と排水配管内面との摩擦係数を減少させることができるコーティング技術であれば、どのような潤滑技術を採用しても構わない。   Also, the type of lubrication coating is not limited to the water-repellent coating as in the above embodiment, and any lubrication coating can be used as long as it is a coating technology that can reduce the friction coefficient between the drainage and the drainage pipe inner surface. Technology may be adopted.
