Description

本発明は小便器に関するものである。   The present invention relates to urinals.

特許文献１は従来の小便器を開示している。この小便器は便鉢及び吐水部を備えている。吐水部は便鉢の上端部の左右中央に設けられている。便鉢は、使用状態における水平断面形状において、左右中央部が後方向に窪み左右両端部が前方向に突出し、上下方向に伸びて前方を向いた対向面を有している。この対向面は、下方に向けて徐々に後退しつつ、水平断面形状における曲率半径が徐々に小さくなっている。このため、この小便器は、便鉢の開口部が下方に向けて徐々に幅寸法を狭くし、前方向に突出する部分の幅寸法を小さくすることができる。よって、この小便器は、使用者が便鉢に近づきやすく、使用者の尿が床にこぼれることを抑えることができる。   Patent Document 1 discloses a conventional urinal. This urinal is equipped with a toilet bowl and a water discharge part. The water discharger is provided at the left and right center of the upper end of the toilet bowl. In the horizontal cross-sectional shape in the use state, the left and right center parts are recessed in the back direction, and the left and right end parts project in the front direction, and have a facing surface extending in the up and down direction and facing forward. The opposing surface gradually recedes downward, and the radius of curvature in the horizontal cross-sectional shape gradually decreases. Therefore, in the urinal, the width of the opening of the toilet bowl can be narrowed gradually downward, and the width of the forwardly projecting portion can be reduced. Thus, the urinal can easily access the user's toilet and prevent the user's urine from spilling on the floor.

しかし、特許文献１の小便器は、ボウル面の中央部が後方向に湾曲している。このため、この小便器はボウル面の中央部にスプレッダを取り付ける場合、スプレッダとボウル面の中央部とが密着できないおそれがある。このため、この小便器はボウル面に対してスプレッダの取り付ける向きがばらつくおそれがある。これにより、この小便器はスプレッダから吐水される洗浄水がボウル面に対して流れる方向がばらつき、ボウル面を良好に洗浄できないおそれがある。   However, in the urinal of Patent Document 1, the central portion of the bowl surface is curved backward. Therefore, when the spreader is attached to the center of the bowl surface, the urinal may not be in close contact with the center of the bowl surface. For this reason, there is a risk that the mounting direction of the spreader may vary with respect to the bowl surface. As a result, in this urinal, the washing water discharged from the spreader varies in the flow direction to the bowl surface, and there is a possibility that the bowl surface can not be cleaned well.

本発明は、上記従来の実情に鑑みてなされたものであって、良好に洗浄することができる小便器を提供することを解決すべき課題としている。   The present invention has been made in view of the above-described conventional circumstances, and an object of the present invention is to provide a urinal that can be cleaned well.

本発明の小便器は、使用状態において、前方を向き平面状に形成された平面部、及び前記平面部の左右両側から前方向に湾曲した一対の湾曲面を具備する対向面を有する便鉢と、
前記便鉢の上部で前記平面部に設けられ、前記対向面に沿って洗浄水を吐水する吐水部と、
を備えていることを特徴とする。 The urinal according to the present invention is a toilet bowl having a flat surface facing forward and a flat surface formed in a flat shape, and a pair of curved surfaces curved in the forward direction from both left and right sides of the flat surface in use. ,
A water discharger provided on the flat surface at the upper part of the toilet bowl and discharging the flush water along the opposite surface;

The upper end of the convex portion 11D is located below the upper end of the pair of left and right cleaning stages 11B and extends downward. Specifically, the upper end of the convex portion 11D is located below the upper end of the pair of left and right washing stages 11B and is located in the vicinity of the upper end of the pair of left and right washing stages 11B (see FIGS. 1, 4 and 6). Further, the lower end of the convex portion 11D extends to the lower end portion which is the lower portion of the facing surface 11A. The convex portion 11D is formed so as to gradually project in the forward direction toward the left and right center of the facing surface 11A (see FIG. 7).

At this time, a gap is provided between the lower end of the convex portion 11D provided on the facing surface 11A of the bowl 11 and the outer peripheral edge of the tray 13.

次に、この小便器の動作を説明する。   Next, the operation of this urinal will be described.

図４に示すように、先ず、スプレッダー１２Ａから洗浄水を吐水する。スプレッダー１２Ａは洗浄水を対向面１１Ａに沿って下方向及び左右方向に拡げて吐水する。左右一対の洗浄段１１Ｂの上端は吐水部１２が有するスプレッダー１２Ａの下方に位置している。そして、スプレッダー１２Ａから左右方向に吐水された洗浄水の１部が左右一対の洗浄段１１Ｂの上端に到達し、左右一対の洗浄段１１Ｂに乗って下部前方に案内され流下する。このとき、左右一対の洗浄段１１Ｂに乗った洗浄水の１部は左右一対の洗浄段１１Ｂに案内され流下しつつ、左右一対の洗浄段１１Ｂの左右内側の対向面１１Ａに流下する。   First, as shown in FIG. 4, the spreader 12A discharges washing water. The spreader 12A spreads the wash water in the downward direction and the left and right direction along the facing surface 11A and discharges the water. The upper ends of the pair of left and right washing stages 11B are located below the spreader 12A of the water discharger 12. Then, one part of the washing water spouted in the left and right direction from the spreader 12A reaches the upper ends of the pair of left and right washing stages 11B, rides on the pair of left and right washing stages 11B, and is guided downward to flow downward. At this time, a part of the washing water on the left and right pair of washing stages 11B is guided to the pair of left and right washing stages 11B and flows down to the left and right inner facing surfaces 11A of the pair of left and right washing stages 11B.

そして、スプレッダー１２Ａから下方向に吐水された洗浄水の１部が凸部１１Ｄの上端に到達し、左右一対の洗浄段１１Ｂの間の対向面１１Ａを左右方向に拡がりつつ流下する。詳しくは、凸部１１Ｄは上端から上下方向の中央部に向かうにつれ、左右方向の寸法、及び前方向に突出する寸法が大きくなっている。このため、凸部１１Ｄを流下する洗浄水は凸部１１Ｄによって左右方向に押し拡げられ、左右一対の洗浄段１１Ｂの間の対向面１１Ａを左右方向に拡がりつつ流下する。また、凸部１１Ｄは下端が対向面１１Ａの下部である下端部まで伸びて設けられている。さらに、スプレッダー１２Ａから吐水された洗浄水は対向面１１Ａを流下しつつ重力によって流速が増す。このため、凸部１１Ｄを流下する洗浄水は凸部１１Ｄによって左右一対の洗浄段１１Ｂの間の対向面１１Ａの左右方向に押し拡げられた状態を対向面１１Ａの下端部まで維持することができる。   Then, a portion of the washing water discharged downward from the spreader 12A reaches the upper end of the convex portion 11D, and flows downward while spreading the facing surface 11A between the pair of left and right washing stages 11B in the left-right direction. Specifically, as the convex portion 11D goes from the upper end to the central portion in the vertical direction, the dimension in the left-right direction and the dimension projecting in the front direction increase. For this reason, the washing water flowing down the convex portion 11D is pushed and spread in the left and right direction by the convex portion 11D, and flows downward while spreading the opposing surface 11A between the pair of left and right washing stages 11B in the left and right direction. The lower end of the convex portion 11D is extended to the lower end portion which is the lower portion of the facing surface 11A. Furthermore, the flow rate of wash water discharged from the spreader 12A is increased by gravity while flowing down the opposing surface 11A. For this reason, the washing water flowing down the convex portion 11D can maintain the state in which the convex portion 11D pushes and expands the lateral surface 11A between the pair of right and left cleaning stages 11B to the lower end portion of the opposing surface 11A. .

このように、この小便器は、吐水部１２から吐水された洗浄水が対向面１１Ａを流下し凸部１１Ｄに到達すると、凸部１１Ｄが洗浄水の流れを左右方向に拡げる。このため、この小便器は対向面１１Ａの全体に洗浄水を流すことができる。   As described above, in the urinal, when the flush water discharged from the water discharger 12 flows down the opposing surface 11A and reaches the convex portion 11D, the convex portion 11D extends the flow of flush water in the left-right direction. For this reason, this urinal can flow flush water over the entire facing surface 11A.

したがって、本発明の小便器は良好に洗浄することができる。   Thus, the urinal of the present invention can be cleaned well.

また、この凸部１１Ｄは下端が対向面１１Ａの下端部まで伸びている。このため、この小便器は凸部１１Ｄの上端で対向面１１Ａの左右方向に拡がった洗浄水の流れを対向面１１Ａの下部まで維持することができる。   Further, the lower end of the convex portion 11D extends to the lower end portion of the facing surface 11A. For this reason, this urinal can maintain the flow of the flush water expanded in the left and right direction of the opposing surface 11A at the upper end of the convex portion 11D up to the lower portion of the opposing surface 11A.

また、この便鉢１１は、上端が吐水部１２の下方に位置し、吐水部１２から吐水された洗浄水を下部前方に案内する左右一対の洗浄段１１Ｂを有し、凸部１１Ｄは左右一対の洗浄段１１Ｂの上端の下方から下方向に伸びている。このため、この小便器は、吐水部１２から吐水され左右一対の洗浄段１１Ｂに乗った洗浄水が便鉢１１の下部前方に案内されるため、便鉢１１の下部前方を洗浄することができる。また、この小便器は、左右一対の洗浄段１１Ｂに乗らず対向面１１Ａの左右中央部を流下する洗浄水を凸部１１Ｄによって対向面１１Ａの左右方向に拡げることができるため、左右一対の洗浄段１１Ｂの間の対向面１１Ａを斑無く洗浄することができる。   The toilet bowl 11 has a pair of left and right washing stages 11B, the upper end of which is located below the water discharger 12, and guides the wash water discharged from the water discharger 12 to the lower front. It extends downward from below the upper end of the washing stage 11B. Therefore, since the flush water discharged from the water discharger 12 and placed on the pair of left and right washing stages 11B is guided forward to the lower front of the toilet bowl 11, the lower urinal of the toilet bowl 11 can be cleaned. . Moreover, since this urinal can not spread on the pair of left and right washing stages 11B and flush the washing water flowing down the left and right central portions of the facing surface 11A in the left and right direction of the facing surface 11A by the convex portion 11D. The opposing surface 11A between the steps 11B can be cleaned without spots.

また、この小便器は、便鉢１１の下端に排出口１１Ｃが形成されており、この排出口１１Ｃに載置される目皿１３を備え、凸部１１Ｄの下端と目皿１３の外周縁との間に間隔が設けられている。このため、この小便器は目皿１３の周囲に凸部１１Ｄの下端が隣接して設けられていないため、目皿１３の周囲の便鉢１１表面を滑らかに形成することができ、目皿１３近傍の便鉢１１表面を洗浄水が満遍なく流れることができる。さらに、この小便器は使用者から見え易い目皿１３の周囲の見た目を良好にすることができる。   Further, the urinal is formed with a discharge port 11C at the lower end of the bowl 11, and is provided with a tray 13 placed on the discharge port 11C, and the lower end of the convex portion 11D and the outer peripheral edge of the tray 13 There is a space between them. Therefore, since the lower end of the convex portion 11D is not provided adjacent to the periphery of the tray 13 in this urinal, the surface of the toilet bowl 11 around the tray 13 can be formed smoothly. The flush water can flow evenly over the surface of the adjacent bowl 11. In addition, the urinal can provide a better appearance around the platter 13 which is easy for the user to see.

また、この対向面１１Ａは、使用状態における水平断面形状において、左右中央部が後方向に窪んで湾曲し、下方に向けて曲率半径が徐々に小さくなる。このため、この小便器は、対向面１１Ａが下方に向けて曲率半径が徐々に小さくなるため吐水部１２から吐水された洗浄水が対向面１１Ａの左右中央部に集まりやすい。しかし、この小便器は凸部１１Ｄによって洗浄水を対向面１１Ａの左右方向に拡げることができるため、対向面１１Ａの全体を洗浄水が流れて、良好に洗浄することができる。また、この小便器は下端に向かうにつれ対向面１１Ａの左右方向の幅が小さくなり、使用者が対向面１１Ａに近づきやすくすることができるため、使用者の尿が床にこぼれることを抑えることができる。   Further, in the horizontal cross-sectional shape in the use state, the opposite surface 11A is curved in such a manner that the left and right central portions are recessed backward and curved, and the radius of curvature gradually decreases downward. For this reason, in this urinal, the opposing surface 11A is directed downward and the radius of curvature gradually decreases, so that the flush water discharged from the water discharger 12 is likely to be collected at the left and right central portions of the opposing surface 11A. However, in this urinal, since the flush water can be spread in the left-right direction of the facing surface 11A by the convex portion 11D, the flush water flows in the entire facing surface 11A and the flush can be performed well. In addition, the width of the facing surface 11A in the left and right direction becomes smaller toward the lower end of the urinal, and the user can easily approach the facing surface 11A, so that the urine of the user can be prevented from spilling on the floor it can.

また、この吐水部１２は対向面１１Ａに取り付けられるスプレッダー１２Ａを有しており、対向面１１Ａのスプレッダー１２Ａが取り付けられる部分が平面である。このため、この小便器はスプレッダー１２Ａの取付け面と対向面１１Ａとを容易に密着させることができる。このため、スプレッダー１２Ａから洗浄水を対向面１１Ａに沿ってばらつきなく所望の方向に吐水することができる。また、この小便器は外観を良好にすることができ、さらに、清掃性を良好にすることができる。   Further, the water discharger 12 has a spreader 12A attached to the facing surface 11A, and a portion of the facing surface 11A to which the spreader 12A is attached is a flat surface. Therefore, the urinal can easily bring the mounting surface of the spreader 12A into close contact with the facing surface 11A. For this reason, it is possible to discharge the washing water from the spreader 12A in the desired direction without variation along the facing surface 11A. In addition, the urinal can have a good appearance and can have a good cleanability.
