Description

本発明は、排水ソケット及び排水ソケットを備えた便器に関する。 The present invention relates to a drainage socket and a toilet bowl provided with a drainage socket.

従来、便器の排水管部と床面等に設けられた排水配管との間を繋ぐ排水ソケットが知られている。排水ソケットは、一般に、便器の排水管部に接続される第１接続部と、床面等に設けられた排水配管に接続される第２接続部と、第１接続部と第２接続部との間を繋ぐ排水路本体部と、を備えている。排水ソケットは、下流側に向かって後方に傾斜した傾斜部を有するものがある。このような傾斜部を有する排水ソケットにおいて、例えば下記特許文献１には、排水路本体部の上流端部に、絞り部が設けられたものが記載されている。この排水ソケットは、便器の排水管部からの洗浄水を絞り部に衝突させ、サイホン力を高めるようになっている。 Conventionally, a drainage socket for connecting a drainage pipe portion of a toilet bowl and a drainage pipe provided on a floor surface or the like is known. The drainage socket generally includes a first connection portion connected to the drainage pipe portion of the toilet bowl, a second connection portion connected to a drainage pipe provided on the floor surface or the like, and a first connection portion and a second connection portion. It is equipped with a drainage channel main body that connects the spaces. Some drainage sockets have an inclined portion inclined rearward toward the downstream side. A drainage socket having such an inclined portion, for example, Patent Document 1 below describes a drainage socket in which a throttle portion is provided at an upstream end portion of a drainage channel main body portion. This drainage socket collides the washing water from the drainage pipe portion of the toilet bowl with the throttle portion to increase the siphon force.

しかしながら、上記のような構成では、絞り部の後部に洗浄水とともに流下する紙等が集まりやすい。絞り部の後部に集まった紙等がそこに引っ掛かると、詰まりを生じる虞があるため改善が望まれていた。 However, with the above configuration, paper or the like that flows down together with the washing water tends to collect at the rear portion of the squeezed portion. If the paper or the like collected at the rear part of the squeezed portion is caught there, there is a risk of jamming, so improvement has been desired.

本発明は上記のような事情に基づいて完成されたものであって、絞り部に紙等を引っ掛かりにくくできる排水ソケットを提供することを目的とする。 The present invention has been completed based on the above circumstances, and an object of the present invention is to provide a drainage socket capable of preventing paper or the like from being caught in a throttle portion.

本発明の排水ソケットは、便器の排水管部に接続される第１接続部と、床面等の排水配管に接続される第２接続部と、前記第１接続部と前記第２接続部との間を繋ぐ排水路本体部と、を備え、前記排水路本体部は、下側に向かって前後方向の一方側に傾斜する傾斜部を有し、前記排水路本体部の上流端部には、絞り部が設けられ、前記絞り部のうち前記傾斜部が傾斜する前記一方側に位置する面は、左右方向の中央から左右方向の端側に向かって、前記第１接続部の中心との間の水平方向の距離が大きくなる部分を有するものである。
本発明の排水ソケットを備えた便器は、便器の排水管部を有する便器と、前記排水ソケットと、を備えているものである。
本発明における前後方向の一方側とは、傾斜部の傾斜方向を水平面上に投影したときの水平面上における方向である。本発明における左右方向とは、本発明における前後方向に対して交差する方向である。本発明における上下方向とは、排水ソケットを施工した状態（第２接続部を床面等の排水管部に接続した状態）における上下方向である。 The drainage socket of the present invention includes a first connection portion connected to a drainage pipe portion of a toilet bowl, a second connection portion connected to a drainage pipe such as a floor surface, the first connection portion, and the second connection portion. The drainage channel main body is provided with a drainage channel main body portion connecting between the two, and the drainage channel main body portion has an inclined portion inclined to one side in the front-rear direction toward the lower side, and the upstream end portion of the drainage channel main body portion has. , The surface of the squeezing portion located on one side of the squeezing portion where the inclined portion is inclined is from the center in the left-right direction toward the end side in the left-right direction with the center of the first connection portion. It has a portion where the horizontal distance between them is large.
The toilet bowl provided with the drainage socket of the present invention includes a toilet bowl having a drainage pipe portion of the toilet bowl and the drainage socket.
One side of the front-rear direction in the present invention is the direction on the horizontal plane when the tilting direction of the inclined portion is projected on the horizontal plane. The left-right direction in the present invention is a direction that intersects the front-rear direction in the present invention. The vertical direction in the present invention is the vertical direction in the state where the drainage socket is installed (the state where the second connection portion is connected to the drainage pipe portion such as the floor surface).

本発明によれば、絞り部のうち傾斜部が傾斜する一方側に位置する面は、第１接続部の中心との水平方向の距離が一定の円弧面である場合に比べて、左右方向の両端部が外側に広い。したがって、絞り部の一方側に位置する面の左右方向の中心に紙等が集中しにくく、また流路面積が大きいから紙等が流下しやすい。よって、絞り部に紙等を引っ掛かりにくくできる。 According to the present invention, the surface of the throttle portion located on one side where the inclined portion is inclined is in the left-right direction as compared with the case where the horizontal distance from the center of the first connecting portion is a constant arc surface. Both ends are wide on the outside. Therefore, it is difficult for the paper or the like to concentrate in the center of the surface located on one side of the throttle portion in the left-right direction, and the paper or the like easily flows down because the flow path area is large. Therefore, it is possible to prevent paper or the like from being caught in the squeezed portion.

本発明の好ましい形態を以下に示す。
本発明の排水ソケットにおいて、前記傾斜部の前記一方側とは反対側の面は、上流側よりも下流側が鉛直に近い勾配をなしているものとしてもよい。このような構成によれば、絞り部の一方側に位置する部分に衝突して傾斜部の一方側とは反対側の面に跳ね返った洗浄水は、傾斜部の一方側とは反対側の面の下流側の鉛直に近い勾配によって、勢い良く排水される。したがって、排水路本体部に紙等を引っ掛かりにくくできる。 Preferred embodiments of the present invention are shown below.
In the drainage socket of the present invention, the surface of the inclined portion opposite to the one side may have a slope closer to vertical on the downstream side than on the upstream side. According to such a configuration, the washing water that collides with the portion located on one side of the throttle portion and bounces off the surface opposite to one side of the inclined portion is the surface opposite to one side of the inclined portion. Due to the nearly vertical gradient on the downstream side of the water, it is drained vigorously. Therefore, it is possible to prevent paper or the like from being caught in the drainage channel main body.

また、本発明の排水ソケットは、前記絞り部の前記一方側の面の下流側に、鉛直方向の下方に向かって前記一方側とは反対側に傾斜する傾斜面が設けられているものとしてもよい。このような構成によれば、絞り部の一方側に位置する部分に衝突した洗浄水が傾斜面に沿って傾斜部の一方側とは反対側の面に流下し、傾斜部の一方側とは反対側の面に沿って勢い良く流下するからサイホン力を向上できる。 Further, the drainage socket of the present invention may be provided with an inclined surface on the downstream side of the one-sided surface of the throttle portion, which is inclined downward in the vertical direction and opposite to the one-sided surface. Good. According to such a configuration, the washing water that collides with the portion located on one side of the throttle portion flows down along the inclined surface to the surface opposite to one side of the inclined portion, and is referred to as one side of the inclined portion. The siphon power can be improved because it flows down vigorously along the opposite surface.

また、本発明の排水ソケットは、前記絞り部の前記一方側に位置する部分が、鉛直方向に対して交差方向に広がる段差面を有しているものとしてもよい。このような構成によれば、絞り部の一方側に位置する部分に多量の洗浄水が衝突して、水膜を確実に形成することができるから、サイホンを確実に発生させることができる。 Further, the drainage socket of the present invention may have a stepped surface in which a portion of the throttle portion located on one side thereof extends in a crossing direction with respect to the vertical direction. According to such a configuration, a large amount of washing water collides with a portion located on one side of the throttle portion, and a water film can be reliably formed, so that a siphon can be reliably generated.

また、本発明の排水ソケットは、前記第１接続部が前記便器の排水管部に接続された状態において、前記絞り部の前記一方側に位置する部分が、前記便器の排水管部の前記一方側に位置する部分よりも前記一方側に位置しているものとしてもよい。このような構成によれば、絞り部の一方側に位置する部分が便器の排水管部の一方側に位置する部分より一方側と反対側に位置する場合に比べて、絞り部の一方側に位置する部分に衝突した洗浄水は、傾斜部の一方側とは反対側の面の低い位置に向かう。したがって、絞り部の一方側に位置する部分に衝突した洗浄水と、便器の排水管部から流下する洗浄水とが、傾斜部の低い位置で合流するから、サイホンが発生する水膜形成位置が下がるためサイホン力を強くできる。 Further, in the drainage socket of the present invention, when the first connection portion is connected to the drainage pipe portion of the toilet bowl, the portion located on the one side of the throttle portion is the one of the drainage pipe portion of the toilet bowl. It may be located on one side of the portion located on the side. According to such a configuration, the portion located on one side of the throttle portion is located on one side of the throttle portion as compared with the case where the portion located on one side of the drainage pipe portion of the toilet bowl is located on the opposite side to the one side. The wash water that collides with the located portion goes to a lower position on the surface opposite to one side of the inclined portion. Therefore, the wash water that collides with the portion located on one side of the throttle portion and the wash water that flows down from the drain pipe portion of the toilet bowl merge at a low position of the inclined portion, so that the water film formation position where the siphon is generated is located. Since it is lowered, the siphon power can be strengthened.

As shown in FIG. 3, the pair of side surfaces 35 are substantially parallel and extend linearly in the front-rear direction in a plan view from above. The front surface 36 hangs substantially vertically from the inner edge of the first front step surface 33F. The front surface 36 is curved in an arc shape centered on the center C of the first connecting portion 11 in a plan view from above. The rear surface 37 hangs substantially vertically from the inner edge of the first rear step surface 33R. The rear surface 37 will be described in detail later.

絞り部３０の一方側に位置する部分（絞り部後部３１と称する。）は、図３に示すように、第１後段差面３３Ｒ、第２後段差面３４Ｒ及び後面３７を有している。後面３７は、絞り部後部３１の周面を構成する。後面３７は、図３に示すように、上方からの平面視では、前面３６より大きい半径の円弧形状をなして湾曲している。後面３７は、左右両端３７Ｒ，３７Ｌと第１接続部１１の中心Ｃとの間の水平方向の距離Ｂ１が、左右方向中央と第１接続部１１の中心Ｃとの間の距離Ｂ２よりも大きい。絞り部後部３１と第１接続部１１の中心Ｃとの間の水平方向の距離は、左右方向中央から両端３７Ｒ，３７Ｌに向かって少しずつ増している。なお、絞り部３０は、第１接続部１１の中心Ｃを基準に左右対称である。 As shown in FIG. 3, the portion located on one side of the throttle portion 30 (referred to as the throttle portion rear portion 31) has a first rear step surface 33R, a second rear step surface 34R, and a rear surface 37. The rear surface 37 constitutes the peripheral surface of the rear portion 31 of the throttle portion. As shown in FIG. 3, the rear surface 37 is curved in an arc shape having a radius larger than that of the front surface 36 in a plan view from above. On the rear surface 37, the horizontal distance B1 between the left and right ends 37R and 37L and the center C of the first connecting portion 11 is larger than the distance B2 between the center in the left-right direction and the center C of the first connecting portion 11. .. The horizontal distance between the rear portion 31 of the throttle portion 31 and the center C of the first connecting portion 11 gradually increases from the center in the left-right direction toward both ends 37R and 37L. The throttle portion 30 is symmetrical with respect to the center C of the first connection portion 11.

絞り部後部３１の下流側には、図２に示すように、鉛直方向の下方に向かって前方に傾斜する傾斜面３８が設けられている。傾斜面３８は、第２後段差面３４Ｒの内縁から垂下している（図３参照）。傾斜面３８は、第２後段差面３４Ｒの内縁から排水路本体部１３の傾斜部１４の上流端までわたっている。傾斜面３８は、傾斜部１４の前面２２の下流側２２Ｓに向かうように傾斜している。言い換えると、図２に示すように、傾斜面３８に沿って下方に延長した仮想傾斜面３９は、傾斜部１４の前面２２の下流側２２Ｓと交差する。傾斜面３８は、対向する絞り部３０の前面３６よりも傾斜している。 As shown in FIG. 2, an inclined surface 38 that inclines forward in the vertical direction is provided on the downstream side of the rear portion 31 of the throttle portion. The inclined surface 38 hangs down from the inner edge of the second rear step surface 34R (see FIG. 3). The inclined surface 38 extends from the inner edge of the second rear step surface 34R to the upstream end of the inclined portion 14 of the drainage channel main body portion 13. The inclined surface 38 is inclined toward the downstream side 22S of the front surface 22 of the inclined portion 14. In other words, as shown in FIG. 2, the virtual inclined surface 39 extending downward along the inclined surface 38 intersects the downstream side 22S of the front surface 22 of the inclined portion 14. The inclined surface 38 is inclined more than the front surface 36 of the facing narrowing portion 30.

傾斜面３８は、上方からの平面視では、図３に示すように、後面３７と略平行な円弧形状をなして湾曲している。すなわち傾斜面３８は、左右方向の両端と第１接続部１１の中心Ｃとの間の水平方向の距離が、左右方向中央と第１接続部１１の中心Ｃとの間の水平方向の距離より大きい。 As shown in FIG. 3, the inclined surface 38 is curved in an arc shape substantially parallel to the rear surface 37 in a plan view from above. That is, in the inclined surface 38, the horizontal distance between both ends in the left-right direction and the center C of the first connecting portion 11 is larger than the horizontal distance between the center in the left-right direction and the center C of the first connecting portion 11. large.

次に、本実施例の排水ソケット１０の使用例を説明する。
まず、図１に示すように、排水ソケット１０を用いて便器排水管部４０と排水配管５０とを連結する。排水ソケット１０の第２接続部１２を排水配管５０に接続し、便器排水管部４０を第１接続部１１に挿入する。便器排水管部４０の下端は、パッキン６０のシール部６２の下端より下方に突出する。 Next, a usage example of the drainage socket 10 of this embodiment will be described.
First, as shown in FIG. 1, the toilet bowl drainage pipe portion 40 and the drainage pipe 50 are connected by using the drainage socket 10. The second connection portion 12 of the drainage socket 10 is connected to the drainage pipe 50, and the toilet bowl drainage pipe portion 40 is inserted into the first connection portion 11. The lower end of the toilet bowl drain pipe portion 40 projects downward from the lower end of the seal portion 62 of the packing 60.

第１接続部１１が便器排水管部４０に接続された状態では、図１に示すように、絞り部後部３１が、便器排水管部４０の後部（一方側に位置する部分）４４よりも後側に位置している。言い換えると、絞り部後部３１と傾斜部１４の前面２２との水平方向の距離が、便器排水管部４０の後部４４と傾斜部１４の前面２２との水平方向の距離よりも大きい。 In a state where the first connection portion 11 is connected to the toilet bowl drainage pipe portion 40, as shown in FIG. 1, the throttle portion rear portion 31 is behind the rear portion (portion located on one side) 44 of the toilet bowl drainage pipe portion 40. It is located on the side. In other words, the horizontal distance between the rear portion 31 of the throttle portion 31 and the front surface 22 of the inclined portion 14 is larger than the horizontal distance between the rear portion 44 of the toilet bowl drainage pipe portion 40 and the front surface 22 of the inclined portion 14.

便器排水管部４０から排出された水は、図４に示すように、絞り部後部３１に衝突して下流側に水膜Ｗ１を形成し、早期にサイホンが発生する。絞り部後部３１に衝突した水は、傾斜面３８によって矢印Ａのように下流側２２Ｓに流下する。絞り部後部３１から流下した洗浄水は、下流側２２Ｓにおいて便器排水管部４０から矢印Ｂのように流下した洗浄水と合流し、水膜Ｗ２が形成される。このように水膜形成位置が低いため、強いサイホン力が発生する。下流側２２Ｓに流下した水は、下流側２２Ｓの鉛直に近い傾斜に沿って矢印Ｃのように曲がり部１８へ勢い良く流れ込む。このため、水が下向きに強く引っ張られ、サイホン力がより強くなる。 As shown in FIG. 4, the water discharged from the toilet bowl drain pipe portion 40 collides with the throttle portion rear portion 31 to form a water film W1 on the downstream side, and siphons are generated at an early stage. The water that collides with the rear portion 31 of the throttle portion flows down to the downstream side 22S by the inclined surface 38 as shown by the arrow A. The wash water flowing down from the rear portion 31 of the squeezing portion merges with the wash water flowing down from the toilet bowl drain pipe portion 40 as shown by an arrow B on the downstream side 22S, and a water film W2 is formed. Since the water film formation position is low in this way, a strong siphon force is generated. The water flowing down to the downstream side 22S vigorously flows into the bent portion 18 as shown by an arrow C along a nearly vertical inclination of the downstream side 22S. For this reason, the water is strongly pulled downward and the siphon force becomes stronger.

また、水とともに流下する紙等が絞り部後部３１に集まる。ここで、絞り部後部３１は円弧面に比べて左右方向に広がりが大きいから、紙等が中心に集中しにくい。また、絞り部後部３１が円弧面である場合に比べて絞り部３０における流路面積が広いため、紙等は引っ掛かることなく流下する。紙等は強いサイホン力により水とともに勢いよく下方に引き込まれてスムーズに排出される。 In addition, paper and the like that flow down with water gather at the rear portion 31 of the squeezing portion. Here, since the rear portion 31 of the throttle portion has a larger spread in the left-right direction than the arc surface, it is difficult for paper or the like to concentrate in the center. Further, since the flow path area in the drawing portion 30 is wider than that in the case where the rear portion 31 of the drawing portion has an arc surface, paper or the like flows down without being caught. Paper, etc. is pulled downward with water by a strong siphon force and is discharged smoothly.

次に、上記のように構成された実施例の作用および効果について説明する。
本実施例の排水ソケット１０は、便器４１の排水管部に接続される第１接続部１１と、床面の排水配管５０に接続される第２接続部１２と、第１接続部１１と第２接続部１２との間を繋ぐ排水路本体部１３と、を備えている。排水路本体部１３は、下流側に向かって後方に傾斜する傾斜部１４を有している。排水路本体部１３の上流端部には、絞り部３０が設けられている。絞り部３０の後面３７は、左右方向の両端３７Ｒ，３７Ｌと第１接続部１１の中心Ｃとの間の水平方向の距離Ｂ１が、左右方向の中央と第１接続部１１の中心Ｃとの間の水平方向の距離Ｂ２よりも大きい形状である。この構成によれば、絞り部３０の後面３７は、第１接続部１１の中心Ｃとの水平方向の距離が一定の円弧面である場合に比べて、左右方向の両端部が外側に広い。したがって、絞り部３０の後面３７の中心に紙等が集中しにくく、また流路面積が大きいから紙等が流下しやすい。よって、絞り部後部３１に紙等を引っ掛かりにくくできる。 Next, the actions and effects of the examples configured as described above will be described.
The drainage socket 10 of this embodiment has a first connection portion 11 connected to the drainage pipe portion of the toilet bowl 41, a second connection portion 12 connected to the drainage pipe 50 on the floor surface, and a first connection portion 11 and a first connection portion 11. It is provided with a drainage channel main body 13 that connects the two connecting portions 12. The drainage channel main body 13 has an inclined portion 14 that is inclined rearward toward the downstream side. A throttle portion 30 is provided at the upstream end of the drainage channel main body portion 13. The rear surface 37 of the throttle portion 30 has a horizontal distance B1 between both ends 37R and 37L in the left-right direction and the center C of the first connection portion 11 between the center in the left-right direction and the center C of the first connection portion 11. The shape is larger than the horizontal distance B2 between them. According to this configuration, the rear surface 37 of the throttle portion 30 has both ends in the left-right direction wider outward than in the case where the rear surface 37 of the first connecting portion 11 is an arc surface having a constant horizontal distance from the center C. Therefore, it is difficult for the paper or the like to concentrate on the center of the rear surface 37 of the drawing portion 30, and since the flow path area is large, the paper or the like easily flows down. Therefore, it is possible to prevent paper or the like from being caught in the rear portion 31 of the squeezed portion.

また、傾斜部１４の前面２２は、上流側よりも下流側が鉛直に近い勾配をなしている。この構成によれば、絞り部後部３１から傾斜部１４の前面２２に流下した洗浄水は、前面２２の下流側の鉛直に近い勾配によって勢い良く排水される。したがって、排水路本体部１３に紙等を引っ掛かりにくくできる。 Further, the front surface 22 of the inclined portion 14 has an inclination closer to vertical on the downstream side than on the upstream side. According to this configuration, the washing water flowing down from the rear portion 31 of the throttle portion to the front surface 22 of the inclined portion 14 is vigorously drained by a gradient close to vertical on the downstream side of the front surface 22. Therefore, it is possible to prevent paper or the like from being caught in the drainage channel main body 13.

また、絞り部３０の後面３７の下流側に、鉛直方向の下方に向かって前方に傾斜する傾斜面３８が設けられている。この構成によれば、絞り部後部３１に衝突した洗浄水が傾斜面３８に沿って傾斜部１４の前面２２に流下し、前面２２に沿って勢い良く流下するからサイホン力を向上できる。 Further, on the downstream side of the rear surface 37 of the throttle portion 30, an inclined surface 38 that inclines forward downward in the vertical direction is provided. According to this configuration, the washing water colliding with the rear portion 31 of the throttle portion flows down to the front surface 22 of the inclined portion 14 along the inclined surface 38, and flows down vigorously along the front surface 22, so that the siphon force can be improved.

また、絞り部後部３１が、鉛直方向に対して交差方向に広がる第１段差面３３及び第２段差面３４を有している。この構成によれば、絞り部後部３１に多量の洗浄水が衝突するから、サイホン力を強くできる。 Further, the rear portion 31 of the squeezing portion has a first stepped surface 33 and a second stepped surface 34 extending in the intersecting direction with respect to the vertical direction. According to this configuration, since a large amount of washing water collides with the rear portion 31 of the throttle portion, the siphon force can be increased.

また、第１接続部１１が便器排水管部４０に接続された状態において、絞り部後部３１が、便器排水管部４０の後部４４よりも後側に位置している。この構成によれば、絞り部後部３１が便器排水管部４０の後部４４より前側に位置する場合に比べて、絞り部後部３１から跳ね返った洗浄水は、傾斜部１４の低い位置に向かう。したがって、絞り部後部３１に衝突して跳ね返った洗浄水と、便器排水管部４０から流下する洗浄水とが、傾斜部１４の低い位置で合流するから、サイホンが発生する水膜形成位置が下がるためサイホン力を強くできる。 Further, in a state where the first connection portion 11 is connected to the toilet bowl drainage pipe portion 40, the throttle portion rear portion 31 is located behind the rear portion 44 of the toilet bowl drainage pipe portion 40. According to this configuration, the washing water rebounded from the throttle portion rear portion 31 is directed to the lower position of the inclined portion 14, as compared with the case where the throttle portion rear portion 31 is located on the front side of the toilet bowl drain pipe portion 40 from the rear portion 44. Therefore, the wash water that collides with the rear portion 31 of the throttle portion and bounces off and the wash water that flows down from the toilet bowl drain pipe portion 40 merge at a low position of the inclined portion 14, so that the position where the siphon is generated is lowered. Therefore, the siphon power can be strengthened.

The width dimension (dimension in the inner and outer directions) of the first front step surface 33F and the first rear step surface 33R is substantially the same.

第２段差面３４は、絞り部３０の左右両側に位置する第２側段差面３４Ｓと、絞り部３０の前側に位置する第２前段差面７１とを有している。第２側段差面３４Ｓと第２前段差面７１とは幅寸法（内外方向の寸法）が概ね等しい。 The second stepped surface 34 has a second stepped surface 34S located on both the left and right sides of the throttle portion 30, and a second front stepped surface 71 located on the front side of the throttle portion 30. The width dimension (dimension in the inner and outer directions) of the second step surface 34S and the second front step surface 71 are substantially the same.

絞り部３０の周面は、実施例１と同様、左右一対の側面３５、前面３６、及び後面３７を有している。
絞り部後部３１は、第１後段差面３３Ｒ及び後面３７を有している。後面３７は、実施例１と同様、上方からの平面視では、前面３６より大きい半径の円弧形状をなして湾曲している。 Similar to the first embodiment, the peripheral surface of the drawing portion 30 has a pair of left and right side surfaces 35, a front surface 36, and a rear surface 37.
The rear portion 31 of the throttle portion has a first rear step surface 33R and a rear surface 37. Similar to the first embodiment, the rear surface 37 is curved in an arc shape having a radius larger than that of the front surface 36 in a plan view from above.

絞り部後部３１の下流側には、実施例１と同様、鉛直方向の下方に向かって前方に傾斜する傾斜面３８が設けられている。傾斜面３８は、後面３７の下端から垂下している。傾斜面３８は、実施例１と同様、傾斜部１４の前面２２の下流側２２Ｓに向かうように傾斜している。 Similar to the first embodiment, an inclined surface 38 that inclines forward in the vertical direction is provided on the downstream side of the rear portion 31 of the throttle portion. The inclined surface 38 hangs down from the lower end of the rear surface 37. The inclined surface 38 is inclined toward the downstream side 22S of the front surface 22 of the inclined portion 14, as in the first embodiment.

傾斜面３８は、実施例１と同様、左右方向の両端と第１接続部１１の中心Ｃとの間の水平方向の距離が、左右方向の中央と第１接続部１１の中心Ｃとの間の水平方向の距離より大きい形状をなしている。傾斜面３８は、上方からの平面視では、後面３７よりも緩い円弧形状をなして湾曲している。すなわち傾斜面３８の半径は後面３７の半径より大きい。 Similar to the first embodiment, the inclined surface 38 has a horizontal distance between both ends in the left-right direction and the center C of the first connection portion 11 between the center in the left-right direction and the center C of the first connection portion 11. It has a shape larger than the horizontal distance of. The inclined surface 38 is curved in an arc shape that is looser than that of the rear surface 37 in a plan view from above. That is, the radius of the inclined surface 38 is larger than the radius of the rear surface 37.

以上のように本実施例においては、実施例１と同様、絞り部後部３１における左右方向の両端部が外側に広いから、絞り部後部３１の中心に紙等が集中しにくく、また流路面積が大きいから紙等が流下しやすい。よって、絞り部３０の後部に紙等を引っ掛かりにくくできる。 As described above, in the present embodiment, as in the first embodiment, since both ends of the squeezed portion rear portion 31 in the left-right direction are wide outward, it is difficult for paper or the like to concentrate in the center of the squeezed portion rear portion 31, and the flow path area. Because it is large, paper etc. can easily flow down. Therefore, it is possible to prevent paper or the like from being caught in the rear portion of the squeezing portion 30.

また、実施例１と同様、絞り部後部３１の下流側に、鉛直方向の下方に向かって前方に傾斜する傾斜面３８が設けられている。これにより、絞り部後部３１に当たった洗浄水が傾斜面３８に沿って傾斜部１４の前面２２に流下し、前面２２に沿って勢い良く流下するからサイホン力を向上できる。 Further, as in the first embodiment, an inclined surface 38 that is inclined forward toward the lower part in the vertical direction is provided on the downstream side of the rear portion 31 of the throttle portion.

また、絞り部後部３１が、鉛直方向に対して交差方向に広がる第１段差面３３を有している。この構成によれば、絞り部後部３１に多量の洗浄水が衝突するから、サイホン力を強くできる。 Further, the rear portion 31 of the throttle portion has a first stepped surface 33 that extends in the intersecting direction with respect to the vertical direction. According to this configuration, since a large amount of washing water collides with the rear portion 31 of the throttle portion, the siphon force can be increased.
