Description

本発明は、横配管同士を接続する横配管接続構造、及び、当該横配管接続構造を備えるトイレ設備に関する。   The present invention relates to a horizontal pipe connection structure for connecting horizontal pipes to each other, and a toilet facility including the horizontal pipe connection structure.

従来より、複数連立するブースを備えたパブリックトイレ設備の各ブースにおいて、トイレ室の壁に取り付けられた壁掛け式の便器装置が知られている(例えば、特許文献1参照)。便器装置は便器本体を有しており、便器本体は、便鉢と、便鉢に排泄された固液混合物としての汚物を便器本体から排出する便器排水路出口とを有している。便器排水路出口の開口部には、蛇腹状を有する蛇腹状管部材の一端部が接続されており、蛇腹状管部材の他端部は、トイレ室の壁の内部において略水平に延びるように配置された排水管(横配管)同士を接続する接続管に接続される。便器装置から蛇腹状管部材及び接続管を通して横配管に流入した汚物は、便器装置から排出される勢いによって、横配管において横配管の上流側から下流側へと流通する。   2. Description of the Related Art Conventionally, a wall-mounted toilet device attached to the wall of a toilet room is known in each booth of public toilet facilities including a plurality of booths (see, for example, Patent Document 1). The toilet device has a toilet body, and the toilet body has a toilet bowl and a toilet drainage outlet that discharges filth as a solid-liquid mixture excreted in the toilet bowl from the toilet body. One end of a bellows-like tube member having a bellows shape is connected to the opening of the toilet drainage outlet, and the other end of the bellows-like tube member extends substantially horizontally inside the wall of the toilet room. It is connected to a connecting pipe that connects the drain pipes (lateral pipes) arranged. The filth that flows into the horizontal pipe from the toilet device through the bellows-like pipe member and the connecting pipe flows from the upstream side of the horizontal pipe to the downstream side in the horizontal pipe due to the force discharged from the toilet apparatus.

特開2010−101495号公報JP 2010-101495 A

横配管は、接続管の内周面に沿って接続管に挿入されることより、接続管に接続される。このため、汚物の流路である、横配管の内周面、及び、接続管の内周面により取り囲まれる空間において、横配管の端部の内周面と接続管の内周面との間に段差が形成されることがある。固体混合物である汚物のうちの固体分や紙は、この段差によって流れが阻害されて引っ掛かり、停滞して流れなくなる。特に、壁掛け便器が、オフィスビルなどの3〜5連立等で並んだトイレブースで使用される場合には、便器装置の使用頻度が戸建の場合よりも多い。このため、横配管の途中で汚物・紙が停滞すると、排水不良(排水管内での詰まり等)の懸念が高まるため、オフィスビル等では、汚物・紙を、階下まで落とす縦管まで、横配管の内部において搬送されることが重要である。   The horizontal pipe is connected to the connection pipe by being inserted into the connection pipe along the inner peripheral surface of the connection pipe. For this reason, in the space surrounded by the inner peripheral surface of the horizontal pipe and the inner peripheral surface of the connection pipe, which is a flow path for dirt, between the inner peripheral surface of the end of the horizontal pipe and the inner peripheral surface of the connection pipe A step may be formed on the surface. Solid matter or paper in the filth that is a solid mixture is caught by this step and is blocked, and stagnate and stops flowing. In particular, when a wall-mounted toilet is used in a toilet booth lined up in 3-5 columns such as an office building, the frequency of use of the toilet device is higher than that in a detached house. For this reason, if filth and paper stagnate in the middle of a horizontal pipe, there is a growing concern about poor drainage (clogging in the drain pipe, etc.). In office buildings, etc., horizontal pipes up to a vertical pipe that drops filth and paper downstairs. It is important that it is transported inside.

さらに近年の節水化に伴い水量が減ることにより、汚物・紙を搬送する搬送性能が落ちるため、さらに、汚物・紙が、階下まで落とされる縦管まで搬送されることの重要度が増しており、節水化しても搬送性能を低下しないようにするには、流下する汚物・紙の勢いを殺さずに下流側へ導くことが必要となる。   Furthermore, as the amount of water decreases with the recent savings in water, the transport performance for transporting filth and paper declines, and the importance of transporting filth and paper to the vertical pipe that drops downstairs is increasing. In order to prevent the conveyance performance from deteriorating even when water is saved, it is necessary to guide the downstream side without killing the momentum of the filth and paper flowing down.

本発明は、横配管の端部の内周面と接続管の内周面との間の段差に汚物等が引っ掛かりにくい、横配管接続構造、及び、トイレ設備を提供することを目的とする。   An object of the present invention is to provide a horizontal pipe connection structure and toilet equipment in which dirt or the like is not easily caught on the step between the inner peripheral surface of the end of the horizontal pipe and the inner peripheral surface of the connection pipe.

前述のように、内周面大径部511、521は、内周面大径部511に接続されている中間筒部53の一端部の内径D11、内周面大径部521に接続されている中間筒部53の他端部の内径D21、に対して、拡径した内径D12、D22をそれぞれ有している。このため、筒状部51の一端部の内周面大径部511と中間筒部53の一端部との接続部分は、内径の差による一端部側段部501を構成している。同様に、筒状部51の他端部の内周面大径部521と中間筒部53の他端部との接続部分は、内径の差による他端部側段部502を構成している。   As described above, the inner peripheral surface large diameter portions 511 and 521 are connected to the inner diameter D11 of the one end portion of the intermediate cylinder portion 53 connected to the inner peripheral surface large diameter portion 511 and the inner peripheral surface large diameter portion 521. The inner cylinder D 53 has an inner diameter D 12 and an expanded inner diameter D 22 with respect to the inner diameter D 21 at the other end of the intermediate cylinder 53. For this reason, the connection part of the inner peripheral surface large diameter part 511 of the one end part of the cylindrical part 51 and the one end part of the intermediate | middle cylinder part 53 comprises the one end part side step part 501 by the difference in an internal diameter. Similarly, the connecting portion between the inner peripheral surface large-diameter portion 521 at the other end of the cylindrical portion 51 and the other end of the intermediate cylindrical portion 53 constitutes the other end portion side step portion 502 due to the difference in inner diameter. .

中間筒部53の一端部の内周面の内径D11と、筒状部51の一端部の内周面大径部511の内径D12との差の1/2の値、即ち、一端部側段部501における、中間筒部53の一端部の内周面と、筒状部の一端部の内周面大径部511の内周面と、の高さの差の値H1は、所定の値未満である。また、中間筒部53の他端部の内周面の内径D21と、筒状部51の他端部の内周面大径部521の内径D22との差の1/2の値、即ち、他端部側段部502における、中間筒部53の他端部の内周面と、筒状部51の他端部の内周面大径部521の内周面と、の高さの差の値H2は、所定の値を超える。ここで、所定の値とは、具体的には、内周面大径部511、521に挿入される横配管200の端部の厚さT1である(内径とは直径を意味するため、内径の差の1/2の値が内径の差により生ずる一端部側段部501、他端部側段部502の高さの値H1、H2であり、この高さと、横配管200の端部の厚さT1と、を比較する)。例えば、一端部側段部501における段差と、他端部側段部502における段差との差が3mm以上あれば、上述の所定の値と、H1と、H2との大小関係は担保される。横配管200としては、「JIS K 6741」で規定されるポリ塩化ビニルパイプ「VP100」が用いられる。   One half of the difference between the inner diameter D11 of the inner peripheral surface of one end portion of the intermediate cylindrical portion 53 and the inner diameter D12 of the inner peripheral surface large diameter portion 511 of one end portion of the cylindrical portion 51, that is, one end portion side step The value H1 of the height difference between the inner peripheral surface of one end portion of the intermediate cylindrical portion 53 and the inner peripheral surface of the inner peripheral surface large-diameter portion 511 at one end portion of the cylindrical portion in the portion 501 is a predetermined value. Is less than. Further, the difference between the inner diameter D21 of the inner peripheral surface of the other end portion of the intermediate cylindrical portion 53 and the inner diameter D22 of the inner peripheral surface large diameter portion 521 of the other end portion of the cylindrical portion 51, that is, The difference in height between the inner peripheral surface of the other end portion of the intermediate cylindrical portion 53 and the inner peripheral surface of the inner peripheral surface large diameter portion 521 of the other end portion of the cylindrical portion 51 in the other end portion side step portion 502. The value H2 exceeds a predetermined value. Here, the predetermined value is specifically the thickness T1 of the end portion of the horizontal pipe 200 inserted into the inner peripheral surface large diameter portions 511 and 521 (the inner diameter means the diameter. The half value of the difference is the height values H1 and H2 of the one end side stepped portion 501 and the other end side stepped portion 502 caused by the difference in inner diameter. Compare the thickness T1). For example, if the difference between the step at the one end side step 501 and the step at the other end side step 502 is 3 mm or more, the magnitude relationship between the above-described predetermined value and H1 and H2 is secured. As the horizontal pipe 200, a polyvinyl chloride pipe “VP100” defined by “JIS K 6741” is used.

図7に示すように、中間筒部53の一端部(内径D11を有する部分)の内周面と中間筒部53の他端部(内径D21を有する部分)の内周面とは、連続的に接続されており、中間筒部53の内周面は、中間筒部53の一端部から、中間筒部53の他端部へ至るまで、一定の割合で縮径している。即ち、中間筒部53の軸心に沿った断面では、中間筒部53の内周面は、中間筒部53の一端部から、中間筒部53の他端部へ至るまで、一定の割合で縮径するテーパー形状を有している。ここで「連続的に接続」とは、中間筒部53の一端部の内周面と中間筒部53の他端部の内周面との間の、中間筒部53の内周面の部分には、凸部や凹部が形成されて不連続な形状となっておらず、中間筒部53の軸心に沿った断面で見た場合には、例えば、図7に示すように、一直線状を有していることを意味する。従って、筒状部51の一端部側の中間筒部53の一端部の内径D11は、筒状部51の他端部側の中間筒部53の他端部の内径D21よりも大きい。   As shown in FIG. 7, the inner peripheral surface of one end portion (portion having an inner diameter D11) of the intermediate cylinder portion 53 and the inner peripheral surface of the other end portion (portion having an inner diameter D21) of the intermediate cylinder portion 53 are continuous. The inner peripheral surface of the intermediate cylinder part 53 is reduced in diameter at a constant rate from one end part of the intermediate cylinder part 53 to the other end part of the intermediate cylinder part 53. That is, in the cross section along the axial center of the intermediate cylinder part 53, the inner peripheral surface of the intermediate cylinder part 53 extends from one end part of the intermediate cylinder part 53 to the other end part of the intermediate cylinder part 53 at a constant rate. It has a tapered shape with a reduced diameter. Here, “continuously connected” means a portion of the inner peripheral surface of the intermediate cylindrical portion 53 between the inner peripheral surface of one end portion of the intermediate cylindrical portion 53 and the inner peripheral surface of the other end portion of the intermediate cylindrical portion 53. In FIG. 7, convex portions and concave portions are not formed to form a discontinuous shape, and when viewed in a cross section along the axial center of the intermediate cylindrical portion 53, for example, as shown in FIG. It means that it has. Accordingly, the inner diameter D11 of one end portion of the intermediate cylindrical portion 53 on the one end portion side of the cylindrical portion 51 is larger than the inner diameter D21 of the other end portion of the intermediate cylindrical portion 53 on the other end portion side of the cylindrical portion 51.

この構成により、前述のように接続管50により互いに接続された横配管200は、全体として流通方向Aにおける上流側から下流側へ向って下るような勾配を有して傾斜して配置されているが、これに対して中間筒部53には、この勾配が緩くなるような勾配が設けられている。本実施形態のように、横配管200の勾配の値が小さい場合には、中間筒部53において、流通方向Aにおける下流側から上流側へ向って下るような逆勾配となるが、この場合であっても、逆勾配の値は小さく、また、中間筒部53は、横配管200と比較して中間筒部53の軸方向における長さは短いため、横配管200における汚物の流れを阻害するには至らない。   With this configuration, the horizontal pipes 200 connected to each other by the connection pipe 50 as described above are disposed with an inclination with a gradient that descends from the upstream side to the downstream side in the flow direction A as a whole. However, the intermediate cylinder portion 53 is provided with a gradient that makes this gradient gentle. As in this embodiment, when the value of the gradient of the horizontal pipe 200 is small, the intermediate cylinder portion 53 has a reverse gradient that descends from the downstream side to the upstream side in the flow direction A. In this case, Even if it exists, since the value of a reverse gradient is small and the intermediate cylinder part 53 is short in the axial direction of the intermediate cylinder part 53 compared with the horizontal pipe 200, the flow of the filth in the horizontal pipe 200 is inhibited. It does not lead to.

図3等に示すように、内周面大径部511、521の外側面には、目盛り513、523が形成されている。内周面大径部511、521の外側面の最上位置に、目盛り513、523の所定の値を合わせることにより、内周面大径部511、521を所定の回転角度として、接続管50に接続される蛇腹状管部材70の曲り具合を適切にすることができるように構成されている。また、中間筒部53の側面には、流通方向Aを示す記載535が形成されている。   As shown in FIG. 3 and the like, scales 513 and 523 are formed on the outer surface of the inner peripheral surface large diameter portions 511 and 521. By adjusting a predetermined value of the scales 513 and 523 to the uppermost position of the outer surface of the inner peripheral surface large diameter portions 511 and 521, the inner peripheral surface large diameter portions 511 and 521 are set to a predetermined rotation angle to the connecting pipe 50. It is comprised so that the bending condition of the bellows-like pipe member 70 connected can be made appropriate. A description 535 indicating the flow direction A is formed on the side surface of the intermediate cylinder portion 53.

ガイド部55は、図7、図8に示すように、筒状部51の中間筒部53の側面から、中間筒部53の外方、且つ、流通方向Aにおける上流側に斜めに分岐して延びる管状を有しており、筒状部51の軸心に平行な面で切断されたような形状を有している。従って、ガイド部55の他端部552の開口は、筒状部51の中間筒部53の半径方向外方へ向って開口し、長手方向が流通方向Aに平行な楕円形状を有している。   As shown in FIGS. 7 and 8, the guide portion 55 branches obliquely from the side surface of the intermediate cylindrical portion 53 of the cylindrical portion 51 to the outside of the intermediate cylindrical portion 53 and the upstream side in the flow direction A. It has a tubular shape that extends, and has a shape that is cut by a plane parallel to the axial center of the tubular portion 51. Accordingly, the opening of the other end portion 552 of the guide portion 55 is open outward in the radial direction of the intermediate cylindrical portion 53 of the cylindrical portion 51 and has an elliptical shape whose longitudinal direction is parallel to the flow direction A. .

より詳細には、図7に示すように、ガイド部55の一端部551は、流通方向Aの下流側において、他端部側段部502に至るまで延びている。流通方向Aの上流側におけるガイド部55の他端部552の開口端縁553は、流通方向Aの上流側における、筒状部51の一端部の内周面大径部511の端縁に至るまで延びている。流通方向Aの上流側のガイド部55の側面555は、蛇腹状管部材70の一端開口部71に流入する汚物の流入方向B(図7における下方向、以下「流入方向B」と言う)に対して、流通方向Aへ汚物の流れを変えるように、流通方向Aの下流側へ向って傾斜している。これに対して流通方向Aの下流側のガイド部55の側面556は、ガイド部55の他端部552から流入方向Bへ平行に延び、途中から流通方向Aへ汚物の流れを変えるように、流通方向Aの下流側へ向って傾斜している。   More specifically, as shown in FIG. 7, one end portion 551 of the guide portion 55 extends to the other end portion side step portion 502 on the downstream side in the flow direction A. The opening edge 553 of the other end 552 of the guide portion 55 on the upstream side in the flow direction A reaches the end edge of the inner peripheral surface large-diameter portion 511 at one end of the cylindrical portion 51 on the upstream side in the flow direction A. It extends to. A side surface 555 of the guide portion 55 on the upstream side in the flow direction A is in the inflow direction B of the filth flowing into the one end opening 71 of the bellows-like tube member 70 (downward direction in FIG. 7, hereinafter referred to as “inflow direction B”). On the other hand, it inclines toward the downstream side of the flow direction A so as to change the flow of filth in the flow direction A. On the other hand, the side surface 556 of the guide portion 55 on the downstream side in the flow direction A extends in parallel to the inflow direction B from the other end portion 552 of the guide portion 55 and changes the flow of filth from the middle to the flow direction A. It inclines toward the downstream side in the flow direction A.

即ち、ガイド部55の一端部(図7に示すガイド部55の下端部)は、中間筒部53の側面に接続され、ガイド部55の他端部(図7に示すガイド部55の上端部)は、蛇腹状管部材70の他端開口部72が接続され、蛇腹状管部材70に流入した汚物が、ガイド部55の他端部からガイド部55の内部に流入し、ガイド部55は、汚物を筒状部51へ流通する。   That is, one end portion of the guide portion 55 (the lower end portion of the guide portion 55 shown in FIG. 7) is connected to the side surface of the intermediate cylinder portion 53, and the other end portion of the guide portion 55 (the upper end portion of the guide portion 55 shown in FIG. 7). ) Is connected to the other end opening 72 of the bellows-like tube member 70, and the filth flowing into the bellows-like tube member 70 flows into the guide portion 55 from the other end of the guide portion 55.

図8に示すように、ガイド部55の他端部の開口の周縁部には、蛇腹状管部材70(図7参照)の他端開口部72が接続されているときに、ガイド部55の他端部の開口の周縁部から蛇腹状管部材70の他端開口部72が外れることを抑制するための滑り止め溝557が、ガイド部55の他端部の開口を一周するように複数形成されている。   As shown in FIG. 8, when the other end opening 72 of the bellows-like tube member 70 (see FIG. 7) is connected to the peripheral edge of the opening at the other end of the guide portion 55, A plurality of anti-slip grooves 557 for preventing the other end opening 72 of the bellows-like tube member 70 from coming off from the peripheral edge of the opening at the other end are formed so as to make a round around the opening at the other end of the guide portion 55. Has been.

ガイド部55の内部空間は、筒状部51の中間筒部53の内部空間に連通している。図4に示すように、流通方向Aにおけるガイド部55の上流側の外面と、下流側の外面には、リブ558、559が設けられている。リブ558、559は、その延長上に筒状部51の軸心を含む位置関係を有する板状を有しており、ガイド部55と筒状部51とを掛け渡すように、ガイド部55及び筒状部51と一体成形されて接続されている。   The internal space of the guide portion 55 communicates with the internal space of the intermediate cylindrical portion 53 of the cylindrical portion 51. As shown in FIG. 4, ribs 558 and 559 are provided on the outer surface on the upstream side and the outer surface on the downstream side of the guide portion 55 in the flow direction A. The ribs 558 and 559 have a plate shape having a positional relationship including the axial center of the tubular portion 51 on the extension thereof, and the guide portion 55 and the tubular portion 51 are bridged between the guide portion 55 and the tubular portion 51.

And is integrally formed of rubber. The one end opening 71 has an annular shape, and is connected to the toilet drainage channel outlet 121 (see FIG. 2) of the toilet device 100. The other end opening 72 has an elliptical annular shape, and covers the entire peripheral edge of the opening of the other end 552 of the guide portion 55 of the connection pipe 50 so as to cover the opening of the other end 552 of the guide portion 55. It is connected to the peripheral part. The bellows-like tube member 70 distributes the filth as a solid-liquid mixture from the toilet device 100 to the connection tube 50.

より詳細には、一端開口部71は、一端開口部接続部711を有している。一端開口部接続部711は、便器装置100の便器排水路出口121に接続可能に構成されており、一端開口部71の開口端縁712からフランジ状に一端開口部71の略半径方向外方へ広がり、そして更に、一端開口部71の開口の軸方向へ延びる形状を有している。他端開口部72は、他端開口部接続部721を有している。他端開口部接続部721は、接続管50のガイド部55の他端部(上端部)に接続可能に構成されており、他端開口部72の開口端縁722からフランジ状に他端開口部72の略半径方向外方へ広がり、そして更に、他端開口部72の開口の軸方向へ延びる形状を有している。一端開口部71の開口は、図6に示すように、流入方向Bにおいて(図7参照)、ガイド部55の一端部寄りの部分の内面(側面555)に対向する。   More specifically, the one end opening 71 has a one end opening connecting portion 711. The one-end opening connection portion 711 is configured to be connectable to the toilet drainage outlet 121 of the toilet device 100, and extends outward from the opening edge 712 of the one-end opening 71 in a flange shape substantially radially outward of the one-end opening 71. It has a shape that extends and further extends in the axial direction of the opening of the one end opening 71. The other end opening 72 has a second end opening connecting portion 721. The other end opening portion connecting portion 721 is configured to be connectable to the other end portion (upper end portion) of the guide portion 55 of the connecting pipe 50, and the other end opening is formed in a flange shape from the opening edge 722 of the other end opening portion 72.

Although located, the downstream end of the bellows portion 731 in the flow direction A has a shape that gradually expands toward the downstream side in the flow direction A as it goes from the upper end to the lower end. Therefore, the edge of the one end opening 71 of the bellows-like tube member 70 on the upstream side in the flow direction A (the left edge shown in FIG. 7) is a solid-liquid flowing into the one end opening 71 of the bellows-like tube member 70.

図5等に示すように、傾斜筒部735は、蛇腹部731の軸心に対して所定の角度で傾斜する軸心を有する略筒状を有している。従って、図5等に示すように、傾斜筒部735の傾斜する方向の側の側面(図5に示す左側の側面)は短く構成され、傾斜筒部735の傾斜する方向の側とは反対の側の側面(図5に示す右側の側面)は長く構成されている。長く構成された側面は、部分的に蛇腹状を有している。   As shown in FIG. 5 and the like, the inclined cylindrical portion 735 has a substantially cylindrical shape having an axis that is inclined at a predetermined angle with respect to the axis of the bellows portion 731. Accordingly, as shown in FIG. 5 and the like, the side surface (the left side surface shown in FIG. 5) in the direction in which the inclined cylinder portion 735 is inclined is configured to be short and is opposite to the side in which the inclined cylinder portion 735 is inclined. The side surface (the right side surface shown in FIG. 5) is long. The long side surface is partially bellows-shaped.

図7等に示すように、蛇腹状管部材70において、他端開口部72は一端開口部71よりも、開口の面積が大きく構成されている。図7に示すように、流通方向Aの上流側における、蛇腹状管部材70の一端開口部71の端縁は、流通方向Aの上流側における、蛇腹状管部材70の他端開口部72が接続される接続管50の開口部の端縁、即ち、流通方向Aの上流側におけるガイド部55の他端部の開口端縁553よりも、僅かに流通方向Aの下流側に位置している。   As shown in FIG. 7 and the like, in the bellows-like tube member 70, the other end opening 72 has a larger opening area than the one end opening 71. As shown in FIG. 7, the edge of the one end opening 71 of the bellows-like tube member 70 on the upstream side in the flow direction A is the other end opening 72 of the bellows-like tube member 70 on the upstream side in the flow direction A. The edge of the opening of the connecting pipe 50 to be connected, that is, the opening edge 553 at the other end of the guide portion 55 on the upstream side in the flow direction A is slightly located on the downstream side in the flow direction A. .

以上の構成を備える本実施形態に係る接続構造を備えるパブリックトイレ設備1における、器具としての便器装置100からの横配管200への汚物等の流れについて説明する。
便器装置100の使用者が便器装置100を使用し終わると、洗浄水は、洗浄水導水路(図示せず)によって、第1吐水口(図示せず)及び第2吐水口(図示せず)に向けて流通させられ、第1吐水口(図示せず)及び第2吐水口(図示せず)から、便鉢11の内部に吐出される。そして、洗浄水は、汚物や紙とともに便器排水路入口(図示せず)及び便器排水路出口121(図2参照)を介して便器装置100の外部に排出され、蛇腹状管部材70の一端開口部71(図7参照)から蛇腹状管部材70の内部へ流入する。
The flow of filth and the like from the toilet apparatus 100 as an appliance to the horizontal pipe 200 in the public toilet facility 1 having the connection structure according to the present embodiment having the above configuration will be described.
When the user of the toilet device 100 finishes using the toilet device 100, the washing water is supplied to the first water outlet (not shown) and the second water outlet (not shown) by the washing water conduit (not shown). And is discharged into the toilet bowl 11 from the first water outlet (not shown) and the second water outlet (not shown). Then, the washing water is discharged to the outside of the toilet apparatus 100 through the toilet drainage channel inlet (not shown) and the toilet drainage channel outlet 121 (see FIG. 2) together with filth and paper, and one end opening of the bellows-like tube member 70 is opened. It flows into the inside of the bellows-like tube member 70 from the portion 71 (see FIG. 7).

このとき、前述のように、蛇腹状管部材70の一端開口部71の端縁は、蛇腹状管部材70の一端開口部71に流入する固液混合物の流入方向B(図7に示す下方向)において、蛇腹状管部材70の中間部分73の蛇腹部731の内周面、及び、蛇腹状管部材70の他端開口部72の開口端縁722に一致する位置関係を有するため、蛇腹状管部材70の一端開口部71から流入した汚物や紙は、蛇腹部731の内周面に直接衝突せずに、蛇腹状管部材70を流通して通過し、接続管50のガイド部55の他端部の開口に流入する。   At this time, as described above, the edge of the one end opening 71 of the bellows-like tube member 70 is in the inflow direction B of the solid-liquid mixture flowing into the one end opening 71 of the bellows-like tube member 70 (downward direction shown in FIG. 7). ), The inner peripheral surface of the bellows portion 731 of the intermediate portion 73 of the bellows-like tube member 70 and the opening end edge 722 of the other end opening 72 of the bellows-like tube member 70 have a positional relationship. The filth and paper flowing in from the one end opening 71 of the tube member 70 do not directly collide with the inner peripheral surface of the bellows portion 731, pass through the bellows-like tube member 70 and pass through the guide portion 55 of the connection tube 50. It flows into the opening at the other end.

ガイド部55に流入したガイド部55の側面555の内面に衝突することにより、流通方向Aにおける下流方向へ流れの向きが変えられ、ガイド部55によって、蛇腹状管部材70に流入した固液混合物としての洗浄水及び汚物等は、流通方向Aにおいて蛇腹状管部材70の他端開口部72よりも下流側の筒状部51の部分へ向けて流通し、ガイド部55の一端部の開口から中間筒部53へ流入する。この際、ガイド部55の一端部は、流通方向Aの下流側において、他端部側段部502に至るまで延びているため、ガイド部55の一端部の開口から中間筒部53へ流入する洗浄水及び汚物等は、接続管50の他端部の内周面大径部521に接続されて他端部側段部502に位置している、流通方向Aの下流側の横配管200−2の端部の端縁よりも、流通方向Aの下流側を狙うように、図7の斜め右下方向へ向って流入する。そして、横配管200−2へ流入した汚物は、横配管200−2において流通方向Aの下流側へ流通し、横配管200の最下流端部に接続されている縦配管300へ流通する。   By colliding with the inner surface of the side surface 555 of the guide portion 55 that has flowed into the guide portion 55, the flow direction is changed in the downstream direction in the flow direction A, and the solid-liquid mixture that has flowed into the bellows-like tube member 70 by the guide portion 55. The cleaning water, the filth, and the like circulate toward the portion of the cylindrical portion 51 on the downstream side of the other end opening 72 of the bellows-like tube member 70 in the flow direction A, and from the opening at one end of the guide portion 55. It flows into the intermediate cylinder part 53. At this time, since one end portion of the guide portion 55 extends to the other end portion side step portion 502 on the downstream side in the flow direction A, the one end portion of the guide portion 55 flows into the intermediate cylindrical portion 53 from the opening. Washing water, filth, and the like are connected to the inner peripheral surface large-diameter portion 521 at the other end of the connecting pipe 50 and are located at the other end side stepped portion 502, and are connected to the downstream side piping 200- in the flow direction A. It flows in toward the diagonally lower right direction in FIG. 7 so as to aim at the downstream side in the flow direction A from the end edge of the second end portion. And the filth which flowed into the horizontal piping 200-2 distribute | circulates to the downstream of the distribution direction A in the horizontal piping 200-2, and distribute | circulates to the vertical piping 300 connected to the most downstream end part of the horizontal piping 200.

接続管50及び横配管200において汚物等が流通する際には、汚物等は、一端部側段部501と他端部側段部502とを通過する。この際、一端部側段部501においては、流通方向Aの上流側の横配管200−1の端部の内周面の内径D13は、流通方向Aの下流側に位置する筒状部51の内周面(中間筒部53の内周面)の内径D11よりも小さく、流通方向Aの上流側の横配管200−1の端部の内周面は、中間筒部53の端部の半径方向内方に位置している。   When filth or the like flows through the connecting pipe 50 and the horizontal pipe 200, the filth or the like passes through the one end side step 501 and the other end side step 502. At this time, in the one end portion side step portion 501, the inner diameter D13 of the inner peripheral surface of the end portion of the horizontal pipe 200-1 on the upstream side in the flow direction A is equal to that of the cylindrical portion 51 located on the downstream side in the flow direction A. The inner peripheral surface of the end of the horizontal pipe 200-1 on the upstream side in the flow direction A is smaller than the inner diameter D11 of the inner peripheral surface (the inner peripheral surface of the intermediate cylindrical portion 53), and the radius of the end of the intermediate cylindrical portion 53 is Located inward direction.

また、他端部側段部502においては、下流側の横配管200−2に対して、流通方向Aの上流側に位置する筒状部51の内周面の内径D21の方が、流通方向Aの下流側の横配管200−2の端部の内周面の内径D13よりも小さく、横配管200−2の半径方向内方に位置している。このため、筒状部51を流れる汚物や紙等は、一端部側段部501、他端部側段部502において引っ掛かりにくく、横配管200を通して縦配管300へ滞りにくく流通しやすい。   Further, in the other end side stepped portion 502, the inner diameter D21 of the inner peripheral surface of the tubular portion 51 located on the upstream side in the flow direction A is in the flow direction with respect to the downstream side pipe 200-2. It is smaller than the inner diameter D13 of the inner peripheral surface of the end of the horizontal pipe 200-2 on the downstream side of A, and is located inward in the radial direction of the horizontal pipe 200-2. For this reason, filth, paper, and the like flowing through the cylindrical portion 51 are not easily caught in the one end portion side step portion 501 and the other end portion side step portion 502 and are less likely to stagnate to the vertical pipe 300 through the horizontal pipe 200.

上記構成の実施形態による、排水管接続構造、及び、トイレ設備によれば、以下のような効果を得ることができる。
排水管接続構造は、一の横配管200としての上流側の横配管200−1と他の横配管200としての下流側の横配管200−2とを接続し、上流側の横配管200−1から流通する固液混合物を下流側の横配管200−2へ流通する接続管50と、一端開口部71と他端開口部72と蛇腹状を有し一端開口部71と他端開口部72とを接続する中間部分73とを有し、一端開口部71は便器装置100に接続され、他端開口部72は接続管50に接続され、便器装置100からの固液混合物を接続管50へ流通する蛇腹状管部材70と、を備える。
一の横配管200及び他の横配管200において流通する固液混合物の流通方向Aの上流側における、蛇腹状管部材70の一端開口部71の開口端縁712は、流通方向Aの上流側における、蛇腹状管部材70の他端開口部72が接続される接続管50の開口部の開口端縁553よりも、流通方向Aの下流側に位置する。
According to the drain pipe connection structure and the toilet facility according to the embodiment of the above configuration, the following effects can be obtained.
The drain pipe connection structure connects an upstream side horizontal pipe 200-1 as one horizontal pipe 200 and a downstream side horizontal pipe 200-2 as another horizontal pipe 200, and an upstream side horizontal pipe 200-1. A connection pipe 50 that circulates the solid-liquid mixture flowing from the downstream side pipe 200-2, one end opening 71, the other end opening 72, and one end opening 71 and the other end opening 72. The other end opening 72 is connected to the connecting pipe 50, and the solid-liquid mixture from the toilet apparatus 100 is circulated to the connecting pipe 50. And a bellows-like tube member 70.
The opening edge 712 of the one end opening 71 of the bellows-like tube member 70 on the upstream side in the flow direction A of the solid-liquid mixture flowing in one horizontal pipe 200 and the other horizontal pipe 200 is on the upstream side in the flow direction A. The other end opening 72 of the bellows-like tube member 70 is located on the downstream side in the flow direction A with respect to the opening edge 553 of the opening of the connection pipe 50.

この構成により、蛇腹状管部材70に汚物等が流入する際に、蛇腹状管部材70の蛇腹状の内周面に汚物等が衝突しにくく、水の乱流の発生を抑えることができ、節水化されて汚物等を流す水の量が減少した場合であっても、汚物の流速が低下することを抑えることができる。このため、流下する汚物等の勢いを維持して下流側へ導くことができる。   With this configuration, when filth or the like flows into the bellows-like tube member 70, the filth or the like hardly collides with the bellows-like inner peripheral surface of the bellows-like tube member 70, and the generation of turbulent water can be suppressed. Even if it is a case where the quantity of the water which carries out filth etc. by water saving is reduced, it can suppress that the flow rate of filth falls. For this reason, it is possible to guide the downstream side while maintaining the momentum of the filth flowing down.

また、流通方向Aの上流側における、蛇腹状管部材70の一端開口部71の端縁は、蛇腹状管部材70の一端開口部71に流入する固液混合物の流入方向Bから蛇腹状管部材70の一端開口部71を見たときに、流通方向Aの上流側における、蛇腹状管部材70の中間部分73の内方へ突出する蛇腹状管部材70の中間部分73の内周面の突出端部、及び、流通方向Aの上流側における、蛇腹状管部材70の他端開口部72の端縁に一致する位置関係を有する。この構成により、蛇腹状管部材70における流通方向Aの上流側において蛇腹状管部材70に流入した汚物等が不必要に上流側へ膨らんで流れることを抑えることができる。このため、流通方向Aの蛇腹状管部材70の上流側において、水の乱流の発生を抑えることができる。   Further, the end edge of the one end opening 71 of the bellows-like tube member 70 on the upstream side in the flow direction A is the bellows-like tube member from the inflow direction B of the solid-liquid mixture flowing into the one end opening 71 of the bellows-like tube member 70. When the one end opening 71 of 70 is viewed, the inner peripheral surface protrusion of the intermediate portion 73 of the bellows-like tube member 70 protruding inward of the intermediate portion 73 of the bellows-like tube member 70 on the upstream side in the flow direction A. It has a positional relationship that coincides with the edge of the other end opening 72 of the bellows-like tubular member 70 on the end and the upstream side in the flow direction A. With this configuration, it is possible to suppress the filth and the like flowing into the bellows-like tube member 70 on the upstream side in the flow direction A of the bellows-like tube member 70 from unnecessarily bulging and flowing upstream. For this reason, it is possible to suppress the occurrence of turbulent water on the upstream side of the bellows-like tube member 70 in the flow direction A.

また、接続管50は、筒状部51と、ガイド部55と、を有する。
ガイド部55の一端部は、筒状部51の側面に接続され、ガイド部55の他端部は、蛇腹状管部材70の他端開口部72に接続され、流入方向Bにおいて、蛇腹状管部材70の一端開口部71の開口は、ガイド部55の一端部寄りの部分の内面(側面555)に対向し、ガイド部55は、蛇腹状管部材70に流入した固液混合物を、流通方向Aにおいて蛇腹状管部材70の他端開口部72よりも下流側の筒状部51の部分へ向けて流通する。
筒状部51の他端部は、筒状部51の内周面に沿って他の横配管200の端部を挿入可能に、筒状部51の他端部近傍の部分の内径に対して拡径した内周面大径部521を有し、内周面大径部521の内周面と筒状部51の他端部近傍の部分の内周面(中間筒部53の内周面)とは、内径の差による他端部側段部502を形成する。ガイド部55の一端部は、流通方向Aにおいて、他端部側段部502まで延びている。
Further, the connecting pipe 50 includes a cylindrical part 51 and a guide part 55.
One end portion of the guide portion 55 is connected to the side surface of the tubular portion 51, the other end portion of the guide portion 55 is connected to the other end opening 72 of the bellows-like tube member 70, and in the inflow direction B, the bellows-like tube The opening of the one end opening 71 of the member 70 is opposed to the inner surface (side surface 555) of the portion near one end of the guide portion 55, and the guide portion 55 allows the solid-liquid mixture flowing into the bellows-like tube member 70 to flow in the flow direction. In A, it circulates toward the portion of the cylindrical portion 51 downstream of the other end opening 72 of the bellows-like tube member 70.
The other end portion of the tubular portion 51 can be inserted into the end portion of the other horizontal pipe 200 along the inner peripheral surface of the tubular portion 51 with respect to the inner diameter of the portion in the vicinity of the other end portion of the tubular portion 51. The inner peripheral surface large-diameter portion 521 having an enlarged diameter is provided, and the inner peripheral surface of the inner peripheral surface large-diameter portion 521 and the inner peripheral surface in the vicinity of the other end of the cylindrical portion 51 (the inner peripheral surface of the intermediate cylindrical portion 53) ) Forms the other end side stepped portion 502 due to the difference in inner diameter. One end portion of the guide portion 55 extends to the other end portion side step portion 502 in the flow direction A.

この構成により、ガイド部55へ流入した汚物等を、ガイド部55によって案内して、他端部側段部502よりも下流側を狙うように、他端部側段部502における接続管50の軸心寄りの方向へ流すことができる。このため、主として汚物等を他端部側段部502に衝突するように流さずに、極力他端部側段部502を回避するように汚物等を流すことができる。この結果、他端部側段部502に汚物等を引っ掛かりにくくすることができる。   With this configuration, the filth or the like that has flowed into the guide portion 55 is guided by the guide portion 55 and aimed at the downstream side of the other end portion side step portion 502, so that the connecting pipe 50 in the other end portion step portion 502 is guided. It can flow in the direction closer to the axis. For this reason, filth etc. can be flowed so that it may avoid the other end part side step part 502 as much as possible, without mainly flowing filth etc. so that it may collide with the other end side step part 502. As a result, it is possible to make it difficult to catch filth on the other end side stepped portion 502.

また、パブリックトイレ設備1においては、器具は、便器装置100を構成し、横配管200は、複数の便器装置100にそれぞれ接続された接続管50同士を連結し、横配管200は、複数の横配管200の一端側から他端側に向って下るように傾斜して配置されている。この構成により、使用頻度の高いパブリックトイレ設備1においても、排水不良の懸念が少ない状態で、便器装置100を使用することができる。   In the public toilet facility 1, the appliances constitute the toilet device 100, the horizontal pipe 200 connects the connection pipes 50 respectively connected to the plurality of toilet apparatuses 100, and the horizontal pipe 200 includes a plurality of horizontal pipes 200. The pipe 200 is disposed so as to be inclined from one end side toward the other end side. With this configuration, the toilet device 100 can be used even in the public toilet facility 1 that is frequently used, with less fear of poor drainage.

また、上記構成の実施形態による、横配管接続構造によれば、以下のような効果を得ることができる。
横配管接続構造は、一の横配管200としての上流側の横配管200−1と他の横配管200としての下流側の横配管200−2とを接続し、上流側の横配管200−1から流通する固液混合物を下流側の横配管200−2へ流通する接続管50を備える。接続管50は、中間筒部を有する筒状部51を備えている。筒状部51の一端部は、筒状部51の内周面に沿って上流側の横配管200−1の端部を挿入可能に、筒状部51の一端部近傍の部分の内径に対して拡径した内径を有する内周面大径部511を有している。筒状部51の他端部は、筒状部51の内周面に沿って下流側の横配管200−2の端部を挿入可能に、筒状部51の他端部近傍の部分の内径に対して拡径した内径を有する内周面大径部521を有している。
筒状部51の一端部の内周面大径部511と他端部の内周面大径部521とは、中間筒部53により接続される。筒状部51の一端部側の中間筒部53の一端部の内径D11は、筒状部51の他端部側の中間筒部53の他端部の内径D21よりも大きい。中間筒部53の一端部の内周面と、筒状部51の一端部の内周面大径部511の内周面とは、一端部側段部501を形成する。一端部側段部501における段差、即ち、中間筒部53の一端部の内周面の内径D11と、筒状部51の一端部の内周面大径部511の内径との差(高さH1)は、所定の値未満である。中間筒部53の他端部の内周面と、筒状部51の他端部の内周面大径部521の内周面とは、他端部側段部502を形成する。他端部側段部502における段差、即ち、中間筒部53の他端部の内周面の内径と、筒状部51の他端部の内周面大径部521の内径との差(高さH2)は、所定の値を超える。
Further, according to the horizontal pipe connection structure according to the embodiment having the above-described configuration, the following effects can be obtained.
The horizontal pipe connection structure connects an upstream side horizontal pipe 200-1 as one horizontal pipe 200 and a downstream side horizontal pipe 200-2 as another horizontal pipe 200, and an upstream side horizontal pipe 200-1. A connecting pipe 50 that circulates the solid-liquid mixture that circulates to the horizontal pipe 200-2 on the downstream side. The connecting pipe 50 includes a cylindrical portion 51 having an intermediate cylindrical portion. One end portion of the tubular portion 51 can be inserted into the end portion of the upstream side pipe 200-1 along the inner peripheral surface of the tubular portion 51 with respect to the inner diameter of the portion near the one end portion of the tubular portion 51. It has an inner peripheral surface large-diameter portion 511 having an inner diameter that is expanded. The other end portion of the cylindrical portion 51 has an inner diameter in the vicinity of the other end portion of the cylindrical portion 51 so that the end portion of the downstream side pipe 200-2 can be inserted along the inner peripheral surface of the cylindrical portion 51. The inner peripheral surface large-diameter portion 521 has an inner diameter that is larger than the inner diameter.
The inner peripheral surface large diameter portion 511 at one end of the cylindrical portion 51 and the inner peripheral surface large diameter portion 521 at the other end are connected by an intermediate cylindrical portion 53. An inner diameter D11 of one end portion of the intermediate cylindrical portion 53 on the one end portion side of the cylindrical portion 51 is larger than an inner diameter D21 of the other end portion of the intermediate cylindrical portion 53 on the other end portion side of the cylindrical portion 51. The inner peripheral surface of one end portion of the intermediate cylindrical portion 53 and the inner peripheral surface of the inner peripheral surface large diameter portion 511 of one end portion of the cylindrical portion 51 form an end portion side step portion 501. The difference (height) between the step in the one end portion side step 501, that is, the inner diameter D11 of the inner peripheral surface of one end portion of the intermediate cylindrical portion 53 and the inner diameter of the inner peripheral surface large diameter portion 511 of one end portion of the cylindrical portion 51. H1) is less than a predetermined value. The inner peripheral surface of the other end portion of the intermediate cylindrical portion 53 and the inner peripheral surface of the inner peripheral surface large diameter portion 521 of the other end portion of the cylindrical portion 51 form the other end portion side step portion 502. The difference between the step in the other end side step 502, that is, the inner diameter of the inner peripheral surface of the other end of the intermediate cylindrical portion 53 and the inner diameter of the inner peripheral surface large diameter portion 521 of the other end of the cylindrical portion 51 ( The height H2) exceeds a predetermined value.

この構成により、所定の値の厚さT1を有する上流側の横配管200−1の端部を筒状部51の一端部の内周面大径部511に挿入すると、上流側の横配管200−1の端部の内周面と、筒状部51の一端部近傍の中間筒部53の内周面とにより段差が生ずる。この段差においては、流通方向Aの上流側の横配管200−1の端部の内周面の内径の方が、流通方向Aの下流側に位置する筒状部51の内周面(中間筒部53の内周面)の内径よりも小さく、中間筒部53の内周面の半径方向内方に位置しているため、上流側の横配管200−1から流れる汚物や紙等が、この段差に引っ掛かりにくい。   With this configuration, when the end portion of the upstream side horizontal pipe 200-1 having a predetermined thickness T <b> 1 is inserted into the inner peripheral surface large diameter portion 511 at one end of the cylindrical portion 51, the upstream side horizontal pipe 200. A difference in level occurs between the inner peripheral surface of the end portion of -1 and the inner peripheral surface of the intermediate cylindrical portion 53 in the vicinity of one end portion of the cylindrical portion 51. In this step, the inner diameter of the inner peripheral surface of the end portion of the horizontal pipe 200-1 on the upstream side in the flow direction A is the inner peripheral surface (intermediate tube) of the cylindrical portion 51 located on the downstream side in the flow direction A. Is smaller than the inner diameter of the inner circumferential surface of the portion 53 and is located radially inward of the inner circumferential surface of the intermediate cylindrical portion 53, so that dirt, paper, etc. flowing from the upstream side pipe 200-1 It is hard to get caught on a step.

同様に、所定の値の厚さT1を有する下流側の横配管200−2の端部を筒状部51の他端部の内周面大径部521に挿入すると、下流側の横配管200−2の端部の内周面と、筒状部51の他端部近傍の中間筒部53の内周面とにより段差が形成される。この段差においては、下流側の横配管200−2に対して、流通方向Aの上流側に位置する筒状部51の内周面(中間筒部53の内周面)の内径の方が、流通方向Aの下流側の横配管200−2の端部の内周面の内径よりも小さく、横配管200及び筒状部51の半径方向内方に位置しているため、筒状部51を流れる汚物や紙等が、この段差に引っ掛かりにくい。   Similarly, when the end portion of the downstream side horizontal pipe 200-2 having a predetermined thickness T1 is inserted into the inner peripheral surface large diameter portion 521 at the other end of the cylindrical portion 51, the downstream side horizontal pipe 200 is provided. A step is formed by the inner peripheral surface of the end portion of -2 and the inner peripheral surface of the intermediate cylindrical portion 53 in the vicinity of the other end portion of the cylindrical portion 51. In this step, the inner diameter of the inner peripheral surface of the cylindrical portion 51 (the inner peripheral surface of the intermediate cylindrical portion 53) located on the upstream side in the flow direction A with respect to the downstream side pipe 200-2 is Since it is smaller than the inner diameter of the inner peripheral surface of the end portion of the horizontal pipe 200-2 on the downstream side in the flow direction A and is located radially inward of the horizontal pipe 200 and the cylindrical part 51, the cylindrical part 51 is Flowing filth and paper are not easily caught by this step.

このため、節水化されて汚物等を流す水の量が減少した場合であっても、汚物や紙の流れが、一端部側段部501や他端部側段部502において阻害されて引っ掛かり、停滞して流れなくなることを抑え、流下する汚物・紙の勢いを殺さず下流側へ導くことができ、縦管まで汚物・紙を搬送されやすくすることができる。   For this reason, even when the amount of water that is saved and flows filth etc. is reduced, the flow of filth and paper is hindered and caught in the one end side step 501 and the other end side step 502, It is possible to suppress stagnation and no longer flow, and to guide the filth and paper flowing down to the downstream side without killing, and to facilitate the conveyance of the filth and paper to the vertical pipe.

また、筒状部51の一端部の内周面大径部511の内径D12の値と、筒状部51の他端部の内周面大径部521の内径D22の値とは、同一である。このため、所定の値の厚さT1と、同一の内径D12、D22と等しい外径と、をそれぞれ有する上流側の横配管200−1の端部、下流側の横配管200−2の端部を、一端部側段部501、他端部側段部502へそれぞれ挿入することにより、確実に段差に汚物や紙等が引っ掛かりにくい構成とすることができる。   The value of the inner diameter D12 of the inner peripheral surface large diameter portion 511 at one end of the cylindrical portion 51 and the value of the inner diameter D22 of the inner peripheral surface large diameter portion 521 at the other end of the cylindrical portion 51 are the same. is there. Therefore, the end of the upstream side horizontal pipe 200-1 and the end of the downstream side horizontal pipe 200-2 each having a predetermined thickness T1 and an outer diameter equal to the same inner diameter D12, D22. Are inserted into the one end portion side step portion 501 and the other end portion side step portion 502, respectively, so that it is possible to reliably prevent filth and paper from being caught on the step.

また、中間筒部53の内周面は、中間筒部53の一端部から、中間筒部53の他端部へ至るまで、一定の割合で縮径している。このような構成を有し、中間筒部53において逆勾配を有する場合であっても、中間筒部53と横配管200との間の段差に汚物や紙が引っ掛かりやすい場合と比較して、流下する汚物・紙の勢いが大きく損なわれることを抑えることができる。   Further, the inner peripheral surface of the intermediate cylinder part 53 is reduced in diameter from the one end part of the intermediate cylinder part 53 to the other end part of the intermediate cylinder part 53 at a constant rate. Even if it has such a configuration and the intermediate cylinder part 53 has a reverse slope, it flows down compared to the case where filth and paper are easily caught in the step between the intermediate cylinder part 53 and the horizontal pipe 200. It is possible to prevent the momentum of filth and paper from being greatly impaired.

Moreover, although the connection pipe 50 was connected to the toilet device 100, the object to which the connection pipe is connected is not limited to the toilet device.

また、流通方向Aの上流側における、蛇腹状管部材70の一端開口部71の端縁は、流通方向Aの上流側における、蛇腹状管部材70の他端開口部72が接続される接続管50の開口部の端縁、即ち、流通方向Aの上流側におけるガイド部55の他端部の開口端縁553よりも、僅かに流通方向Aの下流側に位置していたが、この構成に限定されない。例えば、流通方向Aの上流側における、蛇腹状管部材70の一端開口部71の端縁は、流通方向Aの上流側における、蛇腹状管部材70の他端開口部72が接続される接続管50の開口部の端縁、即ち、流通方向Aの上流側におけるガイド部55の他端部の開口端縁553と一致する位置にあってもよい。   Further, the end edge of the one end opening 71 of the bellows-like tube member 70 on the upstream side in the flow direction A is connected to the other end opening 72 of the bellows-like tube member 70 on the upstream side in the flow direction A. The opening edge of 50, that is, the opening edge 553 at the other end of the guide portion 55 on the upstream side in the flow direction A was slightly located on the downstream side in the flow direction A. It is not limited.
