Description
【０００１】
【発明の属する技術分野】
本発明は、排水器の排水口に接続する可撓性を有する排水管に関し、さらに詳しくは、キッチンシンク、洗面水槽、バスタブ等々を含めて、各種水廻りにおける排水器の排水口に接続する排水管に改良を加えて、排水管の配管施設上の便益を図った可撓性排水管に関する。
【０００２】
【従来の技術】
従来より排水器の排水口に接続する可撓性排水管は、その一端にパッキングとナットを嵌着しており、一方可撓部は、形状が蛇腹状で、その凹凸は水平方向に平行で且つその内径は硬管部の内径より大径である。
【０００３】
【発明が解決しようとする課題】
しかるに従来技術では、排水管の一端に嵌着したパッキングとナットは、パッキングのゴム特有の吸着力により取り付けられているに過ぎず、施工時の不手際や、不慮の事故により、その取付位置がずれ、結果、排水器の封水深が変化してしまい、その封水深が短くなった場合、十分な防臭効果を達成できないといったおそれがあった。
【０００４】
上記の問題を解決するために、排水管の一端に嵌着したパッキングとナットが摺動しないように係合させるフランジを突設し、このパッキングとナットを排水管の他端から嵌脱できるように、可撓部を形設する凹凸の内径が硬管部の内径より小径に形成されたものが発明された。
【０００５】
しかるにこの従来技術においても、可撓部を形設する凹凸の内径が硬管部の内径より小径であるため、排水管内への通水が繰り返されるうち、この凹凸部分の内面に汚れが付着して、悪臭発生や排水の便の悪さの原因になっていた。
【０００６】
上記の問題を解決するために、可撓部の外径より大径の内径を有するナットを用いたものも考え得る。
【０００７】
しかるにこの技術においてはナットの内径が可撓部の外径より大径であるため、このナットと嵌合する排水器の排水口も合わせて大径にする必要があり、そうなると排水器の仕様自体を変える必要があり、極めて不経済である。またナットを硬管部に密着させることができず、漏水のおそれがある。
本発明は、これらの欠点を解決するために発明されたものである。
【０００８】
【課題を解決するための手段】
本発明は、各種排水器（１）の排水口に接続する可撓性を有する排水管（７）において、その硬管部（４）の内径よりそれが大径である可撓部（３）は、排水器（１）と排水管（７）を接合させるナット（５）を螺嵌できるよう螺旋状であり、且つ該ナット（５）が掛止するためのフランジ（２）を配設したことを特徴とする可撓性排水管を提供するものである。
【０００９】
【発明の実施の形態】
以下、本発明の実施の形態について、図面に基づいて説明する。
本発明は、キッチンシンク、洗面水槽、バスタブ等々を含む各種水廻りにおける排水器の排水口に接続する可撓部（３）と硬管部（４）で構成された排水管（７）に関し、該可撓部（３）の内径は該硬管部（４）のそれより大径であり、この可撓部（３）を形設する凹凸は、排水器（１）と排水管（７）を接合させるナット（５）を螺嵌できるよう、螺旋状であり、該ナット（５）が掛止するためのフランジ（２）を、排水器（１）の排水口と接合する端側もしくはその周辺に突設していることを特徴とする。尚、この可撓部（３）は図３に示すように排水管において断続的に形設しても、もしくは図４に示すように連続的に形設してもよい。
【００１０】
本発明は以上のような構造でこれを使用する時は、まずナット（５）を、排水管（７）のフランジ（２）を突設していない端側より嵌挿する。それから該ナット（５）が排水管（７）の可撓部（３）に達した際には可撓部（３）の螺旋状の凹凸にナット（５）の小径の方の孔の縁をを合わせて螺嵌させ、ナット（５）を可撓部（７）から嵌通させる。さらにナット（５）をフランジ（２）に当接させて後、排水器（１）と排水管（７）を接合させる。
【００１１】
【発明の効果】
本発明は以上のような構造と使用法であるので、以下の優れた効果を奏する。
（１）排水管に取り付けられた排水器の排水口と螺着するナットは、排水管の一端に形設したフランジに掛止するので、施工時の不手際や不慮の事故によってもその取付位置は変わらず、排水器の封水深も常に一定に保たれ、十分な防臭効果に資する。
【００１２】
（２）また可撓部を形設する凹凸の内径は、硬管部の内径より大径であるので、凹凸の内面に水は当たりにくく、故に汚れが付着しにくいので、高い防臭効果を奏し、排水もスムーズである。

BACKGROUND OF THE INVENTION
The present invention relates to a flexible drainage pipe connected to a drainage outlet of a drainage device, and more particularly, drainage connected to drainage outlets of drainage units in various waters including a kitchen sink, a wash basin, a bathtub and the like. The present invention relates to a flexible drain pipe that is improved on the pipe and has a benefit on the drain pipe piping facility.
[0002]
[Prior art]
Conventionally, a flexible drain pipe connected to a drain outlet of a drainer has a packing and a nut fitted on one end thereof, while the flexible part has a bellows shape and its unevenness is parallel to the horizontal direction. The inner diameter is larger than the inner diameter of the hard tube portion.
[0003]
[Problems to be solved by the invention]
However, in the conventional technology, the packing and nut fitted to one end of the drain pipe are only attached by the adsorption force specific to the rubber of the packing, and the mounting position is shifted due to a mistake in construction or an accident. As a result, when the sealing depth of the drainage device is changed and the sealing depth is shortened, there is a possibility that a sufficient deodorizing effect cannot be achieved.
[0004]
In order to solve the above problem, a flange that engages the packing fitted to one end of the drainage pipe and the nut so as not to slide is projected so that the packing and the nut can be fitted and detached from the other end of the drainage pipe. Further, the invention has been invented in which the inner diameter of the unevenness forming the flexible portion is smaller than the inner diameter of the hard tube portion.
[0005]
However, even in this prior art, since the inner diameter of the unevenness forming the flexible portion is smaller than the inner diameter of the hard tube portion, dirt is adhered to the inner surface of the uneven portion while water is repeatedly passed through the drain pipe. This has caused the generation of odors and poor stool drainage.
[0006]
In order to solve the above-described problem, a nut using a nut having an inner diameter larger than the outer diameter of the flexible portion can be considered.
[0007]
However, in this technology, since the inner diameter of the nut is larger than the outer diameter of the flexible part, it is necessary to make the drain outlet of the drainage fitting with the nut larger in diameter. Is very uneconomical. Further, the nut cannot be brought into close contact with the hard tube portion, and there is a risk of water leakage.
The present invention has been invented to solve these drawbacks.
[0008]
[Means for Solving the Problems]
The present invention provides a flexible drainage pipe (7) having a larger diameter than the inner diameter of its hard pipe part (4) in a flexible drainage pipe (7) connected to drainage ports of various drainage devices (1). Has a spiral shape so that a nut (5) for joining the drainage device (1) and the drain pipe (7) can be screwed, and a flange (2) for engaging the nut (5) is provided. A flexible drain pipe characterized by the above is provided.
[0009]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
The present invention relates to a drain pipe (7) composed of a flexible part (3) and a hard pipe part (4) connected to drain outlets of drainers around various waters including kitchen sinks, wash basins, bathtubs, etc. The inner diameter of the flexible part (3) is larger than that of the hard pipe part (4), and the concavities and convexities forming the flexible part (3) are the drainer (1) and the drain pipe (7). The nut (5) to be joined with a screw is spiral, and the flange (2) for latching the nut (5) is connected to the drain outlet of the drainage device (1) or its end side It is characterized by protruding around. The flexible portion (3) may be formed intermittently in the drain pipe as shown in FIG. 3, or continuously as shown in FIG.
[0010]
When the present invention is used in the structure as described above, the nut (5) is first inserted from the end side where the flange (2) of the drain pipe (7) is not projected. Then, when the nut (5) reaches the flexible part (3) of the drain pipe (7), the edge of the smaller diameter hole of the nut (5) is formed on the spiral irregularities of the flexible part (3). And the nut (5) is inserted through the flexible portion (7). Furthermore, after making a nut (5) contact | abut to a flange (2), a drainage device (1) and a drain pipe (7) are joined.
[0011]
【The invention's effect】
Since the present invention has the structure and usage as described above, the following excellent effects can be obtained.
(1) The nut screwed to the drain outlet of the drain attached to the drain pipe is hooked to the flange formed at one end of the drain pipe. The drainage seal depth is always kept constant, contributing to a sufficient deodorizing effect.
[0012]
(2) Since the inner diameter of the concave and convex forming the flexible portion is larger than the inner diameter of the hard tube portion, it is difficult for water to hit the inner surface of the concave and convex portion, so that dirt does not easily adhere to the inner surface. The drainage is also smooth.
