Description

本発明は、水洗便器本体の排出口と、床側に配設された排水管との間に配置される排水ソケットに関する。   The present invention relates to a drain socket disposed between a discharge port of a flush toilet body and a drain pipe disposed on a floor side.

水洗便器本体の後方下面に汚物を排出するために設けられた排出口と、床側に配設された排水管との接続部分には、通常、排水ソケットが配置されている。従来の排水ソケットとして、例えば、特許文献1記載のものがある。特許文献1記載の排水ソケットにおいては、その流出口側にオリフィスが形成され、当該オリフィスの上流側に絞りが設けられている。このような構造とすれば、サイホン作用を早期に発生させることができるため、洗浄水量が抑制され、節水を図ることができる。   In general, a drain socket is disposed at a connection portion between a discharge port provided for discharging filth on the rear lower surface of the flush toilet body and a drain pipe disposed on the floor side. There exists a thing of patent document 1 as a conventional drain socket, for example. In the drain socket described in Patent Document 1, an orifice is formed on the outlet side, and a throttle is provided on the upstream side of the orifice. With such a structure, the siphon action can be generated at an early stage, so that the amount of washing water is suppressed and water saving can be achieved.

特開平8−260551号公報JP-A-8-260551

特許文献1記載の排水ソケットは、オリフィスおよび絞りを備えているため、便器本体内の汚水が排出された場合、絞りおよびオリフィスによって汚水の流下が妨げられ、排水ソケット内に、一時的に汚水の塊(以下、「水膜」という。)が形成される。そして、この水膜が排水ソケット内を流下することによってサイホン作用が発生し、汚水全体が排出される。   Since the drain socket described in Patent Document 1 includes an orifice and a throttle, when the sewage in the toilet body is discharged, the sewage is prevented from flowing by the throttle and the orifice, and the sewage is temporarily stored in the drain socket. A lump (hereinafter referred to as “water film”) is formed. And when this water film flows down in the drain socket, a siphon action occurs, and the entire sewage is discharged.

しかしながら、この排水ソケットにおける絞りおよびオリフィスは汚水の流下を妨げるだけであり、その作用にも限界があるため、排水開始直後の汚水の大部分は流下してしまう。このため、排水ソケット内に、水膜が形成されにくく、サイホン作用を早期に発生させることができないのが実状である。従って、洗浄水量を抑制し、節水を図るという目的も充分に達成されていない。   However, the throttle and orifice in the drain socket only prevent the sewage from flowing down, and its action is limited, so that most of the sewage immediately flows after the drainage starts. For this reason, it is difficult to form a water film in the drain socket and the siphon action cannot be generated at an early stage. Therefore, the purpose of reducing the amount of washing water and saving water has not been sufficiently achieved.

本発明が解決しようとする課題は、水洗便器のサイホン作用を早期に発生させることにより、洗浄水量を抑制し、節水を図ることができる排水ソケットを提供することにある。   The problem to be solved by the present invention is to provide a drain socket capable of reducing the amount of washing water and saving water by generating the siphon action of a flush toilet at an early stage.

本発明の排水ソケットは、便器本体の排出口に接続される便器接続部と、床側に配設された排水管に接続される排水管接続部と、前記便器接続部と前記排水管接続部とを連通する排水流路の内周面に当該排水流路の軸心方向に向かって突設された棚部と、を備えた排水ソケットにおいて、
前記棚部の上面に、前記軸心に近づくにつれて上方へ変位した部分を有する汚水返し手段を設けたことを特徴とする。
The drain socket of the present invention includes a toilet bowl connecting portion connected to the outlet of the toilet body, a drain pipe connecting portion connected to a drain pipe disposed on the floor side, the toilet connecting portion and the drain pipe connecting portion. In a drain socket provided with a shelf protruding toward the axial direction of the drainage channel on the inner peripheral surface of the drainage channel communicating with the
A sewage returning means having a portion displaced upward as approaching the axial center is provided on the upper surface of the shelf.

このような構成とすれば、便器接続部から排水流路内に流入した汚水は、排水流路の内周面を伝って流下し、棚部の上面に設けられた汚水返し手段の「上方に変位した部分」に衝突することにより、速やかに排水流路の軸心方向へ巻き上げられる。そして、排水流路の軸心方向へ巻き上げられた前記汚水と、排水流路の内周面を伝わらず排水流路の略中央を落下してきた汚水とが衝突することにより、速やかに水膜が形成される。このため、水洗便器のサイホン作用が早期に発生し、比較的少量の洗浄水で汚物を排出することが可能となり、洗浄水量を抑制し、節水を図ることができる。   With such a configuration, the sewage flowing into the drainage channel from the toilet connection part flows down along the inner peripheral surface of the drainage channel, and “upward” of the sewage return means provided on the upper surface of the shelf. By colliding with the “displaced portion”, it is quickly wound up in the axial direction of the drainage flow path. Then, the sewage rolled up in the axial direction of the drainage channel and the sewage that has fallen substantially in the center of the drainage channel without passing through the inner peripheral surface of the drainage channel collide, so that the water film is quickly formed. It is formed. For this reason, the siphon action of a flush toilet occurs early, it becomes possible to discharge filth with a relatively small amount of washing water, and the amount of washing water can be suppressed to save water.

また、本発明の排水ソケットは、便器本体の排出口に接続される便器接続部と、床側に配設された排水管に接続される排水管接続部と、前記便器接続部と前記排水管接続部とを連通する排水流路と、を備えた排水ソケットにおいて、
前記排水管接続部の内径を前記排水流路の内径より小とし、前記排水管接続部と前記排水流路との境界位置に前記排水流路の軸心方向に向かって突出した棚部を設け、前記棚部の上面に、前記排水流路の軸心に近づくにつれて上方へ変位した部分を有する汚水返し手段を設けたことを特徴とする。
Further, the drain socket of the present invention includes a toilet connecting portion connected to the outlet of the toilet body, a drain connecting portion connected to a drain pipe disposed on the floor side, the toilet connecting portion and the drain pipe. In a drain socket provided with a drain channel that communicates with the connection part,
An inner diameter of the drainage pipe connection part is smaller than an inner diameter of the drainage flow path, and a shelf that protrudes toward the axial direction of the drainage flow path is provided at a boundary position between the drainage pipe connection part and the drainage flow path. The upper surface of the shelf is provided with sewage returning means having a portion displaced upward as it approaches the axial center of the drainage channel.

このような構成とすれば、前述と同様、便器接続部から排水流路内に流入した汚水は、排水流路の内周面を伝って流下し、棚部の上面に設けられた汚水返し手段の「上方に変位した部分」に衝突することにより、速やかに排水流路の軸心方向へ巻き上げられる。そして、排水流路の軸心方向へ巻き上げられた前記汚水と、排水流路の内周面を伝わらず排水流路の略中央を落下してきた汚水とが衝突することにより、速やかに水膜が形成される。このため、水洗便器のサイホン作用が早期に発生し、比較的少量の洗浄水で汚物を排出することが可能となり、洗浄水量を抑制し、節水を図ることができる。また、排水管接続部の内径を排水流路の内径より小としたことにより、排水流路を落下する汚水は、当該排水流路と排水管接続部との境界部分でその落下が妨げられるため、速やかなる水膜形成に有効である。   With such a configuration, as described above, the sewage flowing into the drainage channel from the toilet connection part flows down along the inner peripheral surface of the drainage channel, and the sewage returning means provided on the upper surface of the shelf Is immediately wound up in the axial direction of the drainage flow path. Then, the sewage rolled up in the axial direction of the drainage channel and the sewage that has fallen substantially in the center of the drainage channel without passing through the inner peripheral surface of the drainage channel collide, so that the water film is quickly formed. It is formed. For this reason, the siphon action of a flush toilet occurs early, it becomes possible to discharge filth with a relatively small amount of washing water, and the amount of washing water can be suppressed to save water. In addition, by making the inner diameter of the drainage pipe connection portion smaller than the inner diameter of the drainage flow path, the sewage falling through the drainage flow path is prevented from falling at the boundary between the drainage flow path and the drainage pipe connection part. It is effective for rapid water film formation.

また、本発明の排水ソケットは、便器本体の排出口に接続される便器接続部と、床側に配設された排水管に接続される排水管接続部と、前記便器接続部と前記排水管接続部とを連通する排水流路と、を備えた排水ソケットにおいて、
前記排水管接続部の内径を前記排水流路の内径より小とし、前記排水管接続部と前記排水流路との境界位置に前記排水流路の軸心方向に向かって突出した第一棚部を設け、前記排水管接続部の下流側端部の内周面に当該排水管接続部の軸心方向に向かって突出した第二棚部を設け、前記第一棚部、前記第二棚部の少なくとも一方の上面に、前記軸心に近づくにつれて上方へ変位した部分を有する汚水返し手段を設けたことを特徴とする。
Further, the drain socket of the present invention includes a toilet connecting part connected to the outlet of the toilet body, a drain connecting part connected to a drain pipe disposed on the floor side, the toilet connecting part and the drain pipe. In a drain socket provided with a drain channel that communicates with the connection part,
A first shelf that has an inner diameter of the drainage pipe connection portion smaller than an inner diameter of the drainage flow channel and protrudes toward the axial direction of the drainage flow channel at a boundary position between the drainage pipe connection portion and the drainage flow channel A second shelf that protrudes in the axial direction of the drainage pipe connection part on the inner peripheral surface of the downstream end of the drainage pipe connection part, and the first shelf part and the second shelf part The sewage returning means having a portion displaced upward as approaching the axis is provided on at least one of the upper surfaces.

このような構成とすれば、便器接続部から流入して排水流路内を落下する汚水は、第一棚部および第二棚部によって落下が妨げられ、第一棚部、第二棚部の少なくとも一方の上面に設けられた汚水返し手段の「上方に変位した部分」に衝突することにより、排水流路の内周面若しくは排水管接続部の内周面を伝って流下した汚水が速やかに排水流路の軸心方向へ巻き上げられる。そして、巻上げられた前記汚水と第一棚部および第二棚部に衝突せずに排水流路若しくは排水管接続部の略中央を落下してきた汚水とが衝突することにより、速やかに水膜が形成される。このため、水洗便器のサイホン作用が早期に発生し、比較的少量の洗浄水で汚物を排出することが可能となり、洗浄水量を抑制し、節水を図ることができる。   With such a configuration, the sewage flowing from the toilet connection part and falling in the drainage channel is prevented from dropping by the first shelf and the second shelf, and the first shelf and the second shelf By colliding with the “upwardly displaced portion” of the sewage return means provided on at least one upper surface, the sewage that has flowed down along the inner peripheral surface of the drainage channel or the inner peripheral surface of the drainage pipe connection portion is quickly It is wound up in the axial direction of the drainage channel. And when the sewage that has been rolled up collides with the sewage that has fallen in the approximate center of the drainage channel or drainage pipe connection part without colliding with the first shelf part and the second shelf part, a water film is quickly formed. It is formed. For this reason, the siphon action of a flush toilet occurs early, it becomes possible to discharge filth with a relatively small amount of washing water, and the amount of washing water can be suppressed to save water.

ここで、前記汚水返し手段として、排水流路の軸心に向かって上り勾配をなす斜面部を設ければ、便器接続部から流入して排水流路の内周面を伝って落下する汚水は斜面部に衝突することにより、排水流路の軸心方向へ巻き上げられる。そして、巻き上げられた汚水と排水流路の略中央を落下して斜面部と衝突しない汚水とが衝突することにより、速やかに水膜が形成される。従って、水洗便器にサイホン作用が早期に発生し、比較的少量の洗浄水で汚物を排出することが可能となり、洗浄水量を抑制し、節水を図ることができる。   Here, as the sewage returning means, if a slope part that forms an upward slope toward the axial center of the drainage channel is provided, the sewage that flows from the toilet connection part and falls along the inner peripheral surface of the drainage channel is By colliding with the slope portion, it is wound up in the axial direction of the drainage channel. Then, the rolled up sewage and the sewage that does not collide with the sloped part after dropping substantially at the center of the drainage flow path, form a water film quickly. Therefore, siphon action occurs early in the flush toilet, and it becomes possible to discharge filth with a relatively small amount of washing water, thereby reducing the amount of washing water and saving water.

この場合、前記斜面部を、凹曲面、凸曲面若しくは平面のいずれかとすれば、便器接続部から流入して排水流路の内周面を伝って落下する汚水が、より効率的に乱流状態を形成しながら排水流路の軸心方向へ巻き上げられるため、水膜形成作用が高まり、速やかに水膜を形成することができる。   In this case, if the slope portion is any one of a concave curved surface, a convex curved surface, or a flat surface, the sewage flowing from the toilet connection portion and falling along the inner peripheral surface of the drainage channel is more efficiently turbulent. Since the film is wound up in the axial direction of the drainage channel, the water film forming action is enhanced, and the water film can be formed quickly.

一方、前記斜面部の前記軸心側の内周縁に沿って、上方へ突出した堰部を設けることもできる。このような構成とすれば、棚部の上面に衝突した汚水は、さらに効率的に乱流状態を形成しながら排水流路の軸心方向へ巻き上げられるため、水膜形成作用を高めることができる。   On the other hand, a dam portion protruding upward can be provided along the inner peripheral edge of the slope portion on the axial center side. With such a configuration, the sewage that has collided with the upper surface of the shelf is rolled up in the axial direction of the drainage flow path while more efficiently forming a turbulent state, so that the water film forming action can be enhanced. .

また、前記汚水返し手段として、前記軸心に向かって上り勾配をなす階段部を設ければ、棚部の上面に衝突した汚水は、効率的に乱流状態を形成しながら排水流路の軸心方向へ巻き上げるため、水膜形成作用がさらに高まる。   In addition, if a staircase portion that rises upward toward the axis is provided as the sewage return means, the sewage that collides with the upper surface of the shelf portion efficiently forms a turbulent flow state while the shaft of the drainage channel. Since it rolls up to a heart direction, the water film formation effect further increases.

さらに、前記排水流路の内周面と、前記棚部または前記第一棚部の上面との間に、下方へ向かうにつれて前記軸心方向へ突出するガイド部材を設けることもできる。このような構成とすれば、便器接続部から排水流路内に流入する汚水中の固形物は、ガイド部材に接触することにより、排水流路の軸心方向へ誘導されるため、固形物が棚部に衝突して、その上面に残留するのを防止することができる。   Furthermore, a guide member that protrudes in the axial direction as it goes downward can be provided between the inner peripheral surface of the drainage channel and the upper surface of the shelf or the first shelf. With such a configuration, the solid matter in the sewage flowing into the drainage channel from the toilet connection part is guided in the axial direction of the drainage channel by contacting the guide member. It can prevent colliding with a shelf part and remaining on the upper surface.

本発明により、水洗便器のサイホン作用を早期に発生させることにより、洗浄水量を抑制し、節水を図ることができる、排水ソケットを提供することができる。   ADVANTAGE OF THE INVENTION By this invention, the drainage socket which can suppress the amount of washing water and can aim at water saving by generating the siphon effect | action of a flush toilet early can be provided.

以下、図面に基づいて、本発明の実施の形態について説明する。図1は本発明の第1実施形態である排水ソケットを示す平面図、図2は図1におけるA−A線断面図、図3は図1に示す排水ソケットを水洗便器に配設した状態を示す縦断面図である。   Hereinafter, embodiments of the present invention will be described with reference to the drawings. 1 is a plan view showing a drain socket according to the first embodiment of the present invention, FIG. 2 is a sectional view taken along line AA in FIG. 1, and FIG. 3 is a state in which the drain socket shown in FIG. It is a longitudinal cross-sectional view shown.

図1〜図3に示すように、本実施形態の排水ソケット1は、洋式水洗便器の一つである便器本体20の排出口21に接続される便器接続部22と、便器本体20が設置される床23側に配設された排水管24に接続される排水管接続部25と、便器接続部22と排水管接続部25とを連通する排水流路26の内周面26aに排水流路26の軸心C方向に向かって突設された棚部27と、を備えている。排水管接続部25は、棚部27から連続して形成されており、その内径寸法は排水流路26の内径寸法より小さい。棚部27の上面には、汚水返し手段として、軸心Cに近づくにつれて上方へ変位した部分、即ち、軸心Cに向かって上り勾配をなす斜面部27aを設けている。   As shown in FIGS. 1 to 3, the drain socket 1 of the present embodiment is provided with a toilet bowl connecting portion 22 connected to a discharge port 21 of a toilet bowl body 20 that is one of Western-style flush toilets, and a toilet bowl body 20. The drainage channel 25 is connected to the drainage pipe 24 connected to the drainage pipe 24 disposed on the floor 23 side, and the drainage channel 26a is connected to the inner peripheral surface 26a of the drainage channel 26 that connects the toilet bowl connection 22 and the drainage pipe connection 25. 26, and a shelf 27 projecting in the direction of the axial center C. The drain pipe connecting portion 25 is formed continuously from the shelf 27, and the inner diameter dimension thereof is smaller than the inner diameter dimension of the drain passage 26. On the upper surface of the shelf 27, as a sewage return means, a portion displaced upward as it approaches the axis C, that is, a slope part 27 a that forms an upward gradient toward the axis C is provided.

また、排水流路26の内周面26aと、棚部27の上面(斜面部27a)との間に、下方へ向かうにつれて軸心C方向へ突出するリブ状のガイド部材28を複数設けている。これらのガイド部材28は、棚部27の斜面部27a上に、軸心Cを中心にして放射状をなすように等角度間隔で立設されている。ガイド部材28は合計12個設けているが、これに限定するものではないので、増減可能である。   Further, a plurality of rib-shaped guide members 28 that protrude in the direction of the axis C as it goes downward are provided between the inner peripheral surface 26 a of the drainage flow channel 26 and the upper surface (slope portion 27 a) of the shelf portion 27. . These guide members 28 are erected on the inclined surface 27 a of the shelf 27 at equal angular intervals so as to form a radial shape about the axis C. A total of 12 guide members 28 are provided, but the number of guide members 28 is not limited to this, and can be increased or decreased.

排水ソケット1において、便器接続部22から排水流路26内に流入した汚水のうち、内周面26aを伝って落下した汚水は棚部27の上面に設けられた斜面部27aに衝突することにより、排水流路26の軸心C方向へ巻き上げられる。そして、巻き上げられた前記汚水と、斜面部27aに衝突せずに落下してきた汚水とが衝突することにより、速やかに水膜が形成される。このため、便器本体20のサイホン作用が早期に発生し、比較的少量の洗浄水で汚物を排出することが可能となり、洗浄水量を抑制し、節水を図ることができる。   In the drain socket 1, the sewage that has fallen along the inner peripheral surface 26 a out of the sewage flowing into the drain channel 26 from the toilet connection part 22 collides with the slope 27 a provided on the upper surface of the shelf 27. The drainage channel 26 is wound up in the direction of the axis C. And the water film is rapidly formed when the sewage wound up and the sewage which has fallen without colliding with the slope part 27a collide. For this reason, the siphon action of the toilet main body 20 occurs early, and it becomes possible to discharge filth with a relatively small amount of washing water, thereby reducing the amount of washing water and saving water.

また、排水流路26の内周面26aと、棚部27の斜面部27aとの間に、下方へ向かうにつれて軸心C方向へ連続的に突出するリブ状のガイド部材28を設けているため、便器接続部22から排水流路26内に流入する汚水中の固形物は、これらのガイド部材28に接触することにより、排水流路26の軸心C方向へ誘導されるため、固形物が棚部27に衝突して、その斜面部27a上に残留するのを防止することができる。   In addition, a rib-shaped guide member 28 that continuously protrudes in the direction of the axis C as it goes downward is provided between the inner peripheral surface 26a of the drainage channel 26 and the slope portion 27a of the shelf 27. The solid matter in the sewage flowing into the drainage flow channel 26 from the toilet connection part 22 is guided in the direction of the axis C of the drainage flow channel 26 by coming into contact with these guide members 28. Colliding with the shelf 27 and remaining on the inclined surface 27a can be prevented.

次に、図4〜図16を参照し、本発明の第2〜14実施形態について説明する。図4〜図16は本発明の第2〜14実施形態である排水ソケットを示す縦断面図である。なお、図4〜図16において、図1〜図3に示す符号と同じ符号を付している部分は、第1実施形態の排水ソケット1の構成部分と同じ構造、機能を有する部分であるため、説明を省略する。   Next, second to fourteenth embodiments of the present invention will be described with reference to FIGS. 4 to 16 are longitudinal sectional views showing drain sockets according to second to fourteenth embodiments of the present invention. In addition, in FIG. 4-16, since the part which attached | subjected the code | symbol same as the code | symbol shown in FIGS. 1-3 is a part which has the same structure and function as the component part of the drain socket 1 of 1st Embodiment. The description is omitted.

図4に示す排水ソケット2は、前述した排水ソケット1におけるガイド部材28を省略した構造である。棚部27の上面に斜面部27aを設けているため、内周面26aを伝って落下した汚水が斜面部27aに衝突して軸心C方向へ巻き上げられ、速やかに水膜が形成される。このため、サイホン作用が早期に発生し、比較的少量の洗浄水で汚物を排出することが可能となり、洗浄水量を抑制し、節水を図ることができる。   The drain socket 2 shown in FIG. 4 has a structure in which the guide member 28 in the drain socket 1 described above is omitted. Since the slope portion 27a is provided on the upper surface of the shelf portion 27, the sewage that has fallen along the inner peripheral surface 26a collides with the slope portion 27a and is wound up in the direction of the axis C, thereby quickly forming a water film. For this reason, siphon action occurs at an early stage, and it becomes possible to discharge filth with a relatively small amount of washing water, thereby reducing the amount of washing water and saving water.

図5に示す排水ソケット3においては、汚水返し手段として、棚部27の上面に斜面部27aを設けるとともに、斜面部27aの軸心C側の内周縁に沿って上方へ突出した堰部27bが設けている。このような構成とすれば、棚部27の斜面部27aに衝突した汚水は、排水流路26の軸心C方向へ巻き上げられるとともに、堰部27bにより汚水を棚部27上に留める作用も生じるため、優れた水膜形成作用を発揮する。   In the drain socket 3 shown in FIG. 5, as a sewage return means, a slope portion 27a is provided on the upper surface of the shelf portion 27, and a weir portion 27b protruding upward along the inner peripheral edge on the axis C side of the slope portion 27a is provided. Provided. With such a configuration, the sewage that collides with the slope 27a of the shelf 27 is wound up in the direction of the axis C of the drainage channel 26, and also has an effect of retaining the sewage on the shelf 27 by the weir 27b. Therefore, it exhibits an excellent water film forming action.

図6に示す排水ソケット4においては、汚水返し手段として、棚部27の上面に、排水流路26の軸心Cに向かって上り勾配をなす階段部27cを設けている。棚部27の階段部27cに衝突した汚水は、排水流路26の軸心C方向へ巻き上げられるとともに、複数の段差を有する階段部27cにより汚水の流動も妨げられるため、優れた水膜形成作用を得ることができる。   In the drain socket 4 shown in FIG. 6, as the sewage returning means, a stepped portion 27 c is formed on the upper surface of the shelf 27, which is inclined upward toward the axis C of the drain passage 26. The sewage that has collided with the stepped portion 27c of the shelf 27 is rolled up in the direction of the axis C of the drainage channel 26, and the flow of sewage is also hindered by the stepped portion 27c having a plurality of steps. Can be obtained.

図7に示す排水ソケット5においては、汚水返し手段として、棚部27の上面に、排水流路26の軸心Cに向かって上り勾配をなす凹曲面27dを設けている。便器接続部22から流入して排水流路26内を落下する汚水は、棚部27の凹曲面27dに衝突することにより、速やかに、排水流路26の軸心C方向へ巻き上げられるため、優れた水膜形成作用を得ることができる。   In the drain socket 5 shown in FIG. 7, a concave curved surface 27 d that forms an upward slope toward the axis C of the drain passage 26 is provided on the upper surface of the shelf 27 as the sewage returning means. Since the sewage flowing from the toilet connection part 22 and falling in the drainage channel 26 collides with the concave curved surface 27d of the shelf part 27, it is quickly rolled up in the direction of the axis C of the drainage channel 26. A water film forming action can be obtained.

図8に示す排水ソケット6においては、排水管接続部25の内径25aを排水流路26の内径26bより小とし、排水流路26と排水管接続部25との境界に位置する排水流路26の内周面26aに、当該排水流路26の軸心C方向に向かって突設された第一棚部29を設け、排水管接続部25の内周面25bの下流側端部に、排水流路26の軸心C方向に向かって突出した第二棚部30を設け、汚水返し手段として、第二棚部30の上面に、軸心Cに近づくにつれて上り勾配をなす斜面部30aを設けている。   In the drain socket 6 shown in FIG. 8, the inner diameter 25 a of the drain pipe connection portion 25 is smaller than the inner diameter 26 b of the drain passage 26 and the drain passage 26 located at the boundary between the drain passage 26 and the drain pipe connection 25. Is provided with a first shelf portion 29 projecting in the direction of the axis C of the drainage flow channel 26, and drainage is provided at the downstream end of the inner peripheral surface 25 b of the drainage pipe connection portion 25.
