【考案の詳細な説明】 〔産業上の利用分野〕 本考案は、流し台等の排水管に備えられる排水用トラッ
プの改良技術に関する。[Detailed Description of the Invention] [Industrial field of application] The present invention relates to an improved technique of a drain trap provided in a drain pipe such as a sink.
従来のパイプをＳ字形に曲げた排水用トラップでは、排
水と共に流された生ごみ等の固形物が曲管部に詰まり易
く、かつ、広い設置スペースを要する上、長期間の不使
用時には水涸れが生じて防臭防虫の機能を逸失する問題
があり、かゝかる不都合を解消できるようにした排水用
トラップが特公昭63-23489号公報によって提案されてい
る。In a conventional drainage trap in which the pipe is bent into an S shape, solid substances such as food waste that are flushed with the drainage are likely to be clogged in the curved pipe part, and a large installation space is required. Japanese Patent Publication No. 63-23489 proposes a drainage trap capable of eliminating such an inconvenience and deodorant insect function.
この排水用トラップは、第10図に示すように、排水の流
出口となる側の管口21を傾斜させると共に、その傾斜面
と鈍角をなす側の管壁22に、前記管口21を傾斜面に沿っ

管口21の外側へ向けて一対の支腕24を設け、この両支腕
24に軸25を架け渡し、一方、弁主体部26と錘保持部27と
を側面形状がくの字形をなすように屈折した弁28の、錘
保持部27に錘29を固定し、この錘保持部27を水平方向に
位置して前記軸25に弁28を揺動自在に取り付け、錘29に
よって弁主体部26が突出片23と一直線上に連なるように
して管口21を塞ぐ方向に付勢してなるもので、上記した
曲管構成の排水用トラップによる不都合が全て解消され
るに至った。As shown in FIG. 10, this drainage trap is configured such that the pipe mouth 21 on the side serving as the drainage outlet is inclined, and the pipe mouth 21 is inclined to the pipe wall 22 on the side forming an obtuse angle with the inclined surface. A projecting piece 23 that closes in a split circle along the surface is provided, and a pair of supporting arms 24 are provided on the projecting piece 23 toward the outside of the tube opening 21, and both supporting arms are provided.
The shaft 25 is bridged over the shaft 24, while the valve main body 26 and the weight holding portion 27 are bent to form a dogleg shape, and the weight 29 is fixed to the weight holding portion 27. A valve 28 is swingably attached to the shaft 25 with the portion 27 positioned in the horizontal direction, and the weight 29 causes the valve main portion 26 to be in line with the projecting piece 23 and urges the pipe opening 21 in the closing direction. As a result, all the inconveniences caused by the drainage trap having the curved pipe structure described above have been eliminated.
ところが、前記弁28を取り付けるための突出片23が排水
流路を狭めるために、流路抵抗が大きくなって水の流れ
が悪くなり、かつ、当該突出片23の突出量を小さくすれ
ばするほど前記錘29の配置部が外方に拡がって、排水用
トラップが大きくなる点で改善の余地があった。However, since the projection piece 23 for mounting the valve 28 narrows the drainage flow path, the flow path resistance increases and the water flow deteriorates, and the smaller the projection amount of the projection piece 23 is, the more There is room for improvement in that the arrangement portion of the weight 29 expands outward and the drain trap becomes large.
本考案は、簡単な改良技術によって上記の問題点を解消
することを目的としている。The present invention aims to solve the above problems by a simple improvement technique.

に特徴を有する。The drain trap according to the present invention, which has achieved the above object, has an annular valve seat continuously connected to the inner surface of a cylindrical body member suspended and supported by a perforated plate mounting member, and two half halves. An arm that forms a circular valve body and is pivotally mounted on the direct downstream side of the valve seat so as to be rotatable about the same support shaft, and the semicircular valve bodies each project above the other valve body. While the members are continuously provided, an elastic seal portion continuously provided on a peripheral portion of an elastic member that covers the entire lower surface of the circular valve body is attached to a peripheral portion of the circular valve body, and the elastic seal portion is provided as a valve. The arm member is characterized in that a weight for biasing and abutting against the seat is provided on the arm member.

By incorporating the piping system, deodorant and insect control that reaches the piping system is achieved.
勿論、円形弁体の上部に水が張ることによっても防臭防
虫が達成される。Of course, the deodorant and insect repellent can also be achieved by filling the upper part of the circular valve body with water.
そして、上記の配管系に水が流されて円形弁体の上部に
水が流れ込むと、その重力によって半円形の弁体が夫々
ウエイトの付勢力に抗して下流側に折り畳まれるように
回動し、弁座流路が開放されて排出される。Then, when water flows into the above-mentioned piping system and flows into the upper part of the circular valve body, the gravity causes the semicircular valve bodies to rotate so as to fold to the downstream side against the biasing force of the weights. Then, the valve seat channel is opened and discharged.

ラップにおける不都合を解消できるに至ったのである。Then, when water flows into the above-mentioned piping system and flows into the upper portion of the circular valve body, the gravity thereof causes each of the semi-circular valve bodies to rotate toward the downstream side against the biasing force of the weight. When the valve seat is opened, the flow path of the valve seat is opened and the water is drained. By closing the valve seat flow path with two circular semicircular valve bodies, the valve seat becomes a flow path resistance. The amount of protrusion can be small, and since the weight for biasing the semi-circular valve element to be closed and closed is located in the flow path, it is not necessary to particularly configure the weight arrangement space in the drain trap. Therefore, the drainage trap can be made compact, and as a whole, the disadvantages of the conventionally proposed drainage trap can be solved by a simple improvement technique.
