As shown in FIGS. 1 to 3, the urinal of the first embodiment includes a toilet bowl 10, a peripheral wall portion 30, and a spreader 50 which is a water spouting tool.
As shown in FIGS. 3 and 4, the toilet bowl 10 has an elevation portion 11 extending in the vertical direction, a bowl-shaped portion 13 continuous with the lower portion of the elevation portion 11, and a bowl-shaped portion 13 continuous with the upper portion of the elevation portion 11. It has a concealing portion 15. The elevation portion 11 forms a toilet bowl surface 10A curved in the left-right direction so that the left-right central portion is recessed rearward in the entire vertical direction. Further, in the left and right central portions of the elevation portion 11, the lower portion extends in the vertical direction substantially vertically, and the upper portion is slightly curved in the vertical direction so as to be an inclined surface inclined diagonally forward toward the upper side. Is forming. Further, the elevation portion 11 has a through hole 11A formed in the upper part of the center on the left and right in the front-rear direction. The elevation portion 11 around the through hole 11A has a toilet bowl surface 10A and its back surface formed flat. Therefore, when the rear portion 53 of the spreader 50, which will be described later, is inserted into the through hole 11A and the spreader 50 is attached to the toilet bowl 10, it can be attached satisfactorily.

The bowl-shaped portion 13 forms a toilet bowl surface 10B that is continuous with the lower portion of the elevation portion 11 and spreads upward in a bowl shape. The bowl-shaped portion 13 projects forward from the elevation portion 11. A drain port 13A is formed at the lower end of the bowl-shaped portion 13. A perforated plate 17 is detachably attached to the drain port 13A from above.

As shown in FIGS. 1 to 3, the toilet bowl surfaces 10A and 10B formed by the elevation portion 11 and the bowl-shaped portion 13 are step portions extending in the vertical direction at symmetrical positions, that is, a pair of left and right cleaning steps 19 Is formed. The upper ends of the pair of left and right cleaning steps 19 are located below the spreader 50 and separated from each other to the left and right, and extend diagonally forward toward the lower part of the front end of the bowl-shaped portion 13. The pair of left and right cleaning steps 19 are formed so that the cleaning water discharged from the spreader 50 flows along the stepped surface and joins at the front end portion of the bowl-shaped portion 13. Therefore, in this urinal, the washing water discharged from the spreader 50 flows well to the bowl-shaped portion 13, and the toilet bowl surface 10A can be washed well.

As shown in FIGS. 3 and 4, the concealing portion 15 is formed by a convex portion protruding forward from the upper end portion of the elevation portion 11 of the toilet bowl 10. The concealing portion 15 extends in the left-right direction over substantially the entire left-right direction at the upper end portion of the elevation portion 11 of the toilet bowl 10. The concealing portion 15 is continuous with the front end edge of the upper wall portion 31 of the peripheral wall portion 30, which will be described later, and the upper surface is formed flush with the upper surface 31A of the upper wall portion 31.

As shown in FIG. 2, the front end edge of the concealing portion 15 has a curved shape in which the left and right central portions are located behind the left and right end portions when viewed from above. The concealing unit 15 conceals the spreader 50, which will be described later, when viewed from above. By forming the concealing portion 15 with a convex portion, the design of the urinal can be neat and the concealing portion 15 that conceals the spreader 50 can be easily formed.

Further, as shown in FIGS. 3 and 4, the front surface 15A of the concealing portion 15 is a curved surface that bulges forward in a cross-sectional shape in the vertical direction. Further, the lower surface of the concealing portion 15 continuous from the lower end of the front surface 15A of the concealing portion 15 to the upper end of the toilet bowl surface 10A is composed of an intermediate surface 15B and a rear end surface 15C. The intermediate surface 15B is a horizontally formed horizontal plane. The rear end surface 15C is a curved surface that bulges diagonally upward toward the rear. Since the intermediate surface 15B on the lower surface of the concealing portion 15 is a horizontal plane, liquid such as water that has traveled from the upper surface of the concealing portion 15 to the front surface 15A easily falls downward on the intermediate surface 15B and flows to the rear end surface 15C side of the concealing portion 15. It's getting harder. Therefore, it is possible to prevent the adhesion of water stains and stains due to liquids such as water transmitted from the upper surface of the concealing portion 15 above the lower surface of the concealing portion 15 and the spreader 50 of the toilet bowl surface 10A.

As shown in FIGS. 5A to 5D, the concealing portion 15 has a protrusion amount from the upper end portion of the toilet bowl surface 10A formed by the elevation portion 11 of the toilet bowl 10 on the left and right ends of the toilet bowl surface 10A.
