Each shelf surface 20 is formed on the surface of the toilet bowl section 10, and guides wash water to the lower front end of the toilet bowl section 10. Each shelf surface 20 is formed symmetrically with respect to the left and right center line of the urinal 1 and is spaced apart from each other in the left and right directions. Each shelf surface 20 has an upper end formed below the spreader 100. The upper end of each shelf surface 20 is located at the boundary between the central elevation section 13A and the left and right elevation sections 13B of the toilet bowl section 10. When viewed from the front, each shelf surface 20 is curved to bulge outward to the left and right so that the interval gradually increases from the upper end to the vicinity of the reaching part X, which will be described later, and the interval gradually narrows from the vicinity of the reaching part X to the lower end. . The surface of the toilet bowl portion 10 located between the shelf surfaces 20 and between the shelf surfaces 20 is a central toilet bowl surface U.

The distance from the virtual plane is greater at the ends (midpoints SP1, SP2, SP3, SP4, SP5, SP6 of the outer curved surface 20SR). The difference between the distance from the virtual plane to the left and right outer edges SP1, SP2, SP3, SP4, SP5, SP6 and the distance from the virtual plane to the left and right center edges UP1, UP2, UP3, UP4, UP5, UP6 is , varies depending on the height of the shelf surface 20. Specifically, the change from the reaching part X to the lower end is larger than the change from the upper end of the shelf surface 20 to the reaching part X.

各棚面20が向いている方向を左右中央側の端部(UP1,UP2、UP3,UP4,UP5、UP6)と左右外側の端部(SP1,SP2,SP3,SP4,SP5,SP6)とを結んだ仮想直線に直交する方向とすると、各棚面20は、上端から下端までの全領域において便鉢部10の左右中央の前方を向いており、仮想平面に対する傾斜角度が下方に向けて徐々に大きくなるように変化している The direction in which each shelf surface 20 is facing is defined by the center left and right ends (UP1, UP2, UP3, UP4, UP5, UP6) and the left and right outer ends (SP1, SP2, SP3, SP4, SP5, SP6). Assuming that the direction is orthogonal to the connected imaginary straight lines, each shelf surface 20 faces in the front of the left and right center of the toilet bowl part 10 in the entire area from the upper end to the lower end, and the inclination angle with respect to the imaginary plane gradually increases downward. is changing to become larger

スプレッダ100から吐水された洗浄水は、図1及び図2に示すように、下方に向けて左右両側に広がり、各棚面20の間の中央便鉢面Uと、各棚面20の左右外側の外側便鉢面Sを流下する。外側便鉢面Sを流れた洗浄水は、棚面20の上端から中間位置までの間で棚面20に到達する。外側便鉢面Sを流れて棚面20に到達した洗浄水は、図7に示すように、棚面20に沿って便鉢部10の下方前端部に向けて流れる流れF1と、棚面20から中央便鉢面Uに流れ落ちる流れF2とを形成する。スプレッダ100に供給される洗浄水は、小便器1に定められた設定水圧範囲内の水圧で供給される。設定水圧範囲内における最小水圧でスプレッダ100に供給され、スプレッダ100から吐水された洗浄水が、外側便鉢面において最も左右外側を流れて棚面20に到達する流れF3は到達部Xに到達する。到達部Xは、正面視において、棚面20の上端から棚面20の上下方向の約2/5の地点である。 As shown in FIGS. 1 and 2, the cleaning water discharged from the spreader 100 spreads downward to both the left and right sides, and reaches the central toilet bowl surface U between each shelf surface 20 and the left and right outer sides of each shelf surface 20. It flows down the outer toilet bowl surface S. The washing water flowing through the outer toilet bowl surface S reaches the shelf surface 20 between the upper end of the shelf surface 20 and an intermediate position. As shown in FIG. 7, the washing water that has flowed on the outer toilet bowl surface S and reached the shelf surface 20 is divided into a flow F1 that flows along the shelf surface 20 toward the lower front end of the toilet bowl section 10, and a flow F1 that flows along the shelf surface 20 toward the lower front end of the toilet bowl section 10. A flow F2 is formed which flows down from the central toilet bowl surface U to the central toilet bowl surface U. The wash water supplied to the spreader 100 is supplied at a water pressure within a set water pressure range defined for the urinal 1. The wash water supplied to the spreader 100 at the minimum water pressure within the set water pressure range and discharged from the spreader 100 flows on the outermost left and right sides of the outer toilet bowl surface and reaches the shelf surface 20. A flow F3 reaches the destination part X. . The reaching portion X is a point about 2/5 of the vertical direction of the shelf surface 20 from the upper end of the shelf surface 20 when viewed from the front.

水平断面形状において、棚面20の内側湾曲面20URの曲率半径は、図6及び図7のUR1,UR2に示すように、上端から徐々に小さくなる。水平断面形状において、棚面20の内側湾曲面20URの曲率半径は、図7及び図8のUR2,UR3に示すように、到達部Xの上方近傍で徐々に大きくなっている。水平断面形状において、棚面20の内側湾曲面20URの曲率半径は、図8及び図9のUR3,UR4に示すように、到達部Xの上下近傍において略一定になっている。水平断面形状において、棚面20の内側湾曲面20URの曲率半径は、図10及び図11のUR5,UR6に示すように、到達部Xよりも下方から下端部に向けて徐々に大きくなっている。水平断面形状において、棚面20の内側湾曲面20URの曲率半径は、棚面20の下端部がそれよりも上流側に比べて大きい。水平断面形状において、図10及び図11に示すように、棚面20の下部において、内側湾曲面20URの曲率半径UR5,UR6は外側湾曲面20SRの曲率半径SR5,SR6よりも大きい。棚面20の一つの水平断面形状における内側湾曲面20URは、一定の曲率半径を有している場合に限らない。棚面20の一つの水平断面形状における内側湾曲面20URが、異なる曲率半径を有する複数の円弧を合成したものである場合、内側湾曲面20URの曲率半径は、実際の内側湾曲面20URの形状に最も近い一定の曲率半径を有する一つの円弧の曲率半径と等しいと見なす。 In the horizontal cross-sectional shape, the radius of curvature of the inner curved surface 20UR of the shelf surface 20 gradually becomes smaller from the upper end, as shown by UR1 and UR2 in FIGS. 6 and 7. In the horizontal cross-sectional shape, the radius of curvature of the inner curved surface 20UR of the shelf surface 20 gradually increases in the upper vicinity of the reaching portion X, as shown by UR2 and UR3 in FIGS. 7 and 8. In the horizontal cross-sectional shape, the radius of curvature of the inner curved surface 20UR of the shelf surface 20 is approximately constant near the top and bottom of the reaching portion X, as shown by UR3 and UR4 in FIGS. 8 and 9. In the horizontal cross-sectional shape, the radius of curvature of the inner curved surface 20UR of the shelf surface 20 gradually increases from below the reaching part X toward the lower end, as shown in UR5 and UR6 of FIGS. 10 and 11. . In the horizontal cross-sectional shape, the radius of curvature of the inner curved surface 20UR of the shelf surface 20 is larger at the lower end of the shelf surface 20 than at the upstream side. In the horizontal cross-sectional shape, as shown in FIGS. 10 and 11, at the lower part of the shelf surface 20, the radius of curvature UR5, UR6 of the inner curved surface 20UR is larger than the radius of curvature SR5, SR6 of the outer curved surface 20SR. The inner curved surface 20UR in one horizontal cross-sectional shape of the shelf surface 20 does not have to have a constant radius of curvature. When the inner curved surface 20UR in one horizontal cross-sectional shape of the shelf surface 20 is a composite of a plurality of circular arcs having different radii of curvature, the radius of curvature of the inner curved surface 20UR is the same as the shape of the actual inner curved surface 20UR. It is assumed that the radius of curvature is equal to the radius of curvature of one circular arc with the nearest constant radius of curvature.

水平断面形状において、棚面20の外側湾曲面20SRの曲率半径は、図6から図8のSR1,SR2,SR3に示すように、上端から徐々に小さくなり、到達部Xの上方から到達部Xにかけて略一定になっている。水平断面形状において、棚面20の外側湾曲面20SRの曲率半径は、図9のSR4に示すように、到達部Xの下方近傍において到達部Xに比べて僅かに大きくなっている。水平断面形状において、到達部Xの下方近傍において外側湾曲面20SRの曲率半径が僅かに大きくなった部分より下方では、外側湾曲面20SRの曲率半径は徐々に小さくなり、棚面20の下部における外側湾曲面20SRの曲率半径は、図10及び図11のSR5,SR6に示すように、略一定になっている。棚面20の一つの水平断面形状における外側湾曲面20SRは、一定の曲率半径を有している場合に限らない。棚面20の一つの水平断面形状における外側湾曲面20SRが、異なる曲率半径を有する複数の円弧を合成したものである場合、外側湾曲面20SRの曲率半径は、実際の外側湾曲面20SRの形状に最も近い一定の曲率半径を有する一つの円弧の曲率半径と等しいと見なす。 In the horizontal cross-sectional shape, the radius of curvature of the outer curved surface 20SR of the shelf surface 20 gradually decreases from the upper end, as shown by SR1, SR2, and SR3 in FIGS. It remains almost constant. In the horizontal cross-sectional shape, the radius of curvature of the outer curved surface 20SR of the shelf surface 20 is slightly larger near the lower part of the reaching part X than that of the reaching part X, as shown by SR4 in FIG. In the horizontal cross-sectional shape, the radius of curvature of the outer curved surface 20SR gradually becomes smaller below the portion where the radius of curvature of the outer curved surface 20SR becomes slightly larger in the lower vicinity of the reaching part The radius of curvature of the curved surface 20SR is substantially constant, as shown by SR5 and SR6 in FIGS. 10 and 11. The outer curved surface 20SR in one horizontal cross-sectional shape of the shelf surface 20 does not have to have a constant radius of curvature. When the outer curved surface 20SR in one horizontal cross-sectional shape of the shelf surface 20 is a composite of a plurality of circular arcs having different radii of curvature, the radius of curvature of the outer curved surface 20SR is the same as the shape of the actual outer curved surface 20SR. It is assumed that the radius of curvature is equal to the radius of curvature of one circular arc with the nearest constant radius of curvature.

水平断面形状において、棚面20の内側湾曲面20URの曲率半径と、外側湾曲面20SRの曲率半径は、図6から図9のUR1,UR2,UR3,UR4,SR1,SR2,SR3,SR4に示すように、棚面20の上部において、内側湾曲面20URの方が外側湾曲面20SRよりも小さい、棚面20の平面20Hが無くなる付近の水平断面形状において、内側湾曲面20URの曲率半径と外側湾曲面20SRとは略等しくなる。水平断面形状において、棚面20の内側湾曲面20URの曲率半径と、外側湾曲面20SRの曲率半径は、図10及び図11のUR5,UR6,SR5,SR6に示すように、棚面20の下部において内側湾曲面20URの方が外側湾曲面20SRよりも大きい。このように、水平断面形状において、棚面は、外側湾曲面の曲率半径と内側湾曲面の曲率半径との大小関係が棚面の上端から下端までの間で入れ替わっている。 In the horizontal cross-sectional shape, the radius of curvature of the inner curved surface 20UR of the shelf surface 20 and the radius of curvature of the outer curved surface 20SR are shown in UR1, UR2, UR3, UR4, SR1, SR2, SR3, SR4 in FIGS. 6 to 9. In the upper part of the shelf surface 20, the inner curved surface 20UR is smaller than the outer curved surface 20SR, and in the horizontal cross-sectional shape near where the plane 20H of the shelf surface 20 disappears, the radius of curvature of the inner curved surface 20UR and the outer curve are It is approximately equal to the surface 20SR. In the horizontal cross-sectional shape, the radius of curvature of the inner curved surface 20UR and the radius of curvature of the outer curved surface 20SR of the shelf surface 20 are as shown in UR5, UR6, SR5, and SR6 of the lower part of the shelf surface 20, as shown in FIGS. Inner curved surface 20UR is larger than outer curved surface 20SR. Thus, in the horizontal cross-sectional shape, the radius of curvature of the outer curved surface and the radius of curvature of the inner curved surface of the shelf surface are interchanged in magnitude from the upper end to the lower end of the shelf surface.

以上説明したように、この小便器1は、左右壁部30の後端面30B、上壁部50の後端面50B、及び後壁部70のリム部71の後端面71Bが構成する壁付け面30B,50B,71Bと、上下方向に延びて洗浄水を下方前端部に誘導する棚面20を有した便鉢部10とを備えている。この小便器1において、水平断面形状において、棚面20は、上端から下端までの全領域において、壁付け面30B,50B,71Bと同一平面上の仮想平面から左右中央側の端部UP1,UP2、UP3,UP4,UP5、UP6までの距離よりも仮想平面から左右外側の端部SP1,SP2,SP3,SP4,SP5,SP6までの距離が大きい。このため、この小便器1は、スプレッダ100から吐水され、外側便鉢面を流れて棚面20に到達した洗浄水が、棚面20の平面20Hに沿って流れつつ、内側便鉢面に流れ落ちる。よって、この小便器1は便鉢部10の中央便鉢面Uを良好に洗浄することができる。 As explained above, this urinal 1 has a wall mounting surface 30B formed by the rear end surfaces 30B of the left and right walls 30, the rear end surface 50B of the upper wall section 50, and the rear end surface 71B of the rim section 71 of the rear wall section 70. , 50B, 71B, and a toilet bowl portion 10 having a shelf surface 20 extending in the vertical direction and guiding wash water to the lower front end. In this urinal 1, in the horizontal cross-sectional shape, the shelf surface 20 has ends UP1, UP2 on the left and right center sides from a virtual plane on the same plane as the wall-mounted surfaces 30B, 50B, 71B in the entire area from the upper end to the lower end. , UP3, UP4, UP5, and UP6, the distances from the virtual plane to the left and right outer ends SP1, SP2, SP3, SP4, SP5, and SP6 are larger. Therefore, in this urinal 1, the wash water that is spouted from the spreader 100, flows on the outer toilet bowl surface, and reaches the shelf surface 20 flows down the inner toilet bowl surface while flowing along the plane 20H of the shelf surface 20. . Therefore, this urinal 1 can clean the central toilet bowl surface U of the toilet bowl part 10 well.

水平断面形状において、棚面20は、上端から下端までの全領域において、仮想平面から左右外側の端部SP1,SP2,SP3,SP4,SP5,SP6までの距離と仮想平面から左右中央側の端部UP1,UP2、UP3,UP4,UP5、UP6までの距離との差が高さによって変化している。このため、この小便器1は、スプレッダ100から吐水され、外側便鉢面を流れて棚面20に到達した洗浄水が、棚面20に沿って流れつつ、内側便鉢面Uに流れ落ちる。よって、この小便器1は便鉢部10の中央便鉢面Uを良好に洗浄することができる。 In the horizontal cross-sectional shape, the shelf surface 20 has a distance from the virtual plane to the left and right outer ends SP1, SP2, SP3, SP4, SP5, and SP6 and an end on the left and right center side from the virtual plane in the entire area from the top end to the bottom end. The difference from the distance to parts UP1, UP2, UP3, UP4, UP5, and UP6 changes depending on the height. Therefore, in this urinal 1, the wash water that is spouted from the spreader 100, flows on the outer toilet bowl surface, and reaches the shelf surface 20 flows down the inner toilet bowl surface U while flowing along the shelf surface 20. Therefore, this urinal 1 can clean the central toilet bowl surface U of the toilet bowl part 10 well.

この小便器1は、棚面20よりも上方の便鉢部10に設けられ、吐水される洗浄水の一部が棚面20よりも左右外側に位置する外側便鉢面Sを流れて棚面20に到達するスプレッダ100を備えている。水平断面形状において、棚面20は、外側便鉢面Sにおいて最も左右外側を流れた洗浄水が棚面20に到達する到達部Xから下端までの領域において、仮想平面から左右外側の端部SP1,SP2,SP3,SP4,SP5,SP6までの距離と仮想平面から左右中央側の端部UP1,UP2、UP3,UP4,UP5、UP6までの距離との差が大きくなる部分を含んでいる。このため、この小便器1は、到達部Xよりも下方において、洗浄水が、棚面20に沿って流れつつ、内側便鉢面Uに流れ落ちる。よって、この小便器1は便鉢部10の中央便鉢面Uを良好に洗浄することができる。 This urinal 1 is provided in the toilet bowl part 10 above the shelf surface 20, and a part of the flushing water that is spouted flows through the outer toilet bowl surface S located on the right and left sides of the shelf surface 20. A spreader 100 reaching 20 is provided. In the horizontal cross-sectional shape, the shelf surface 20 is located at the left and right outer ends SP1 from the virtual plane in the area from the reaching part X where the washing water flowing on the outermost left and right sides of the outer toilet bowl surface S reaches the shelf surface 20 to the lower end. , SP2, SP3, SP4, SP5, and SP6 and the distance from the virtual plane to the left and right center ends UP1, UP2, UP3, UP4, UP5, and UP6. Therefore, in this urinal 1, below the reaching portion X, the flushing water flows down along the shelf surface 20 and onto the inner toilet bowl surface U. Therefore, this urinal 1 can clean the central toilet bowl surface U of the toilet bowl part 10 well.

この小便器1は、棚面20よりも上方の便鉢部10に設けられ、吐水される洗浄水の一部が棚面20よりも左右外側に位置する外側便鉢面Sを流れて棚面20に到達するスプレッダ100を備えている。棚面20は棚面20よりも中央側に位置する中央便鉢面Uに連続した内側湾曲面20URを具備している。この小便器1は、水平断面形状において、外側便鉢面Sにおいて最も左右外側を流れた洗浄水が棚面20に到達する到達部Xよりも下側の内側湾曲面20URの曲率半径UR5,UR6が、到達部Xよりも上側の内側湾曲面20URの曲率半径UR1,UR2,UR3,UR4に比べて大きい。このため、この小便器1は、到達部Xまでの内側湾曲面20URの曲率半径が小さいため、到達部Xまで棚面20から中央便鉢面Uに流れ落ちにくく、棚面20に沿って洗浄水を良好に流すことができる。到達部Xよりも下側の内側湾曲面20URの曲率半径URを徐々に大きくすることによって、到達部Xよりも下方の棚面20から中央便鉢面Uに向けて流れ落ちる洗浄水が別れずに便鉢部10を良好に洗浄することができる。 This urinal 1 is provided in the toilet bowl part 10 above the shelf surface 20, and a part of the flushing water that is spouted flows through the outer toilet bowl surface S located on the right and left sides of the shelf surface 20. A spreader 100 reaching 20 is provided. The shelf surface 20 includes an inner curved surface 20UR that is continuous with a central toilet bowl surface U located closer to the center than the shelf surface 20. This urinal 1 has radii of curvature UR5, UR6 of the inner curved surface 20UR lower than the reaching portion X where the flush water flowing on the outermost left and right sides reaches the shelf surface 20 on the outer toilet bowl surface S in the horizontal cross-sectional shape. is larger than the radius of curvature UR1, UR2, UR3, UR4 of the inner curved surface 20UR above the reaching portion X. Therefore, in this urinal 1, since the radius of curvature of the inner curved surface 20UR up to the reaching part can flow well. By gradually increasing the radius of curvature UR of the inner curved surface 20UR below the reaching portion X, the washing water flowing down from the shelf surface 20 below the reaching portion The toilet bowl part 10 can be cleaned well.

この小便器1の棚面20は、外側湾曲面20SR及び内側湾曲面20URのみから構成された部分を具備している。棚面20を外側湾曲面20SRと内側湾曲面20URのみから構成することによって、その部分の棚面20の掃除を容易に行うことができる。 The shelf surface 20 of this urinal 1 includes a portion consisting only of an outer curved surface 20SR and an inner curved surface 20UR. By configuring the shelf surface 20 only from the outer curved surface 20SR and the inner curved surface 20UR, that portion of the shelf surface 20 can be easily cleaned.

この小便器1の棚面20は、上端から途中まで、外側湾曲面20SR、内側湾曲面20UR、及び平面20Hによって構成されており、途中から下端まで、外側湾曲面20SR及び内側湾曲面20URによって構成されている。棚面20に平面20Hがなくなると洗浄水が棚面20から中央便鉢面Uに向けて流れ落ち易くなるため、下方前端部において合流する洗浄水が少なくなる。このため、この小便器1は、下方前端部において合流する洗浄水が少なくなり、下方前端部における洗浄水の飛散を抑制することができる。 The shelf surface 20 of this urinal 1 is composed of an outer curved surface 20SR, an inner curved surface 20UR, and a flat surface 20H from the upper end to the middle, and is composed of an outer curved surface 20SR and an inner curved surface 20UR from the middle to the lower end. has been done. When the flat surface 20H disappears on the shelf surface 20, the washing water tends to flow down from the shelf surface 20 toward the central toilet bowl surface U, so that less washing water joins at the lower front end. Therefore, in this urinal 1, less washing water joins at the lower front end, and it is possible to suppress splashing of washing water at the lower front end.

この小便器1は、水平断面形状において、棚面20の内側湾曲面20URの曲率半径と、外側湾曲面20SRの曲率半径との大小関係が棚面の上端から下端までの間で入れ替わっている。このため、この小便器1は、外側便鉢面Sを流れて棚面20に到達した洗浄水が、棚面20の平面20Hに沿って流れつつ、内側便鉢面に流れ落ちる。よって、この小便器1は便鉢部10の中央便鉢面Uを良好に洗浄することができる。 In the horizontal cross-sectional shape of this urinal 1, the radius of curvature of the inner curved surface 20UR of the shelf surface 20 and the radius of curvature of the outer curved surface 20SR are interchanged from the upper end to the lower end of the shelf surface. Therefore, in this urinal 1, the flushing water that has flowed on the outer toilet bowl surface S and reached the shelf surface 20 flows down to the inner toilet bowl surface while flowing along the plane 20H of the shelf surface 20. Therefore, this urinal 1 can clean the central toilet bowl surface U of the toilet bowl part 10 well.

水平断面形状において、棚面20は、左右幅が一定の第1領域と、この第1領域の下端に連続して下方に延び、左右幅が下方に向けて徐々に小さくなる第2領域とを有している。第1領域は、棚面20の上端部から到達部X近傍まで延びている。第2領域は、第1領域の下端から棚面20の平面20Hが無くなる付近まで延びている。到達部Xまでは棚面20の左右幅を広くすることによって、到達部Xまで棚面20に沿って洗浄水を良好に流すことができる。到達部Xよりも下側まで棚面20の左右幅を広くすると、上方から棚面20を流れる洗浄水とが合流して、飛散するリスクが下方前端部で大きくなる。このため、第2領域は、棚面20の左右幅を下方に向けて徐々に小さくする。 In the horizontal cross-sectional shape, the shelf surface 20 has a first region with a constant width in the left and right directions, and a second region that extends downward continuously from the lower end of the first region and whose width in the left and right gradually decreases downward. have. The first region extends from the upper end of the shelf surface 20 to the vicinity of the reaching portion X. The second region extends from the lower end of the first region to the vicinity where the plane 20H of the shelf surface 20 disappears. By widening the horizontal width of the shelf surface 20 up to the reaching section X, the washing water can flow well along the shelf surface 20 up to the reaching section X. If the horizontal width of the shelf surface 20 is widened below the reaching part X, the risk of washing water flowing on the shelf surface 20 from above joining together and scattering increases at the lower front end. Therefore, in the second region, the horizontal width of the shelf surface 20 is gradually reduced downward.
