Conventionally, a washing water distribution structure in a urinal has been proposed in an earlier application by the present applicant (Utility Application No. 167356/1986).
There is an unknown item related to No. 62-77284.
That is, in this structure, as shown in FIGS. 3 to 5, a water supply port 4 that communicates with the water supply chamber 3 above the toilet bowl 2 is bored in the upper surface of the urinal body 1, and the bottom of the water supply chamber 3 is opened. In the wall 3a, a plurality of water injection holes 5, 5... for flushing the toilet bowl are bored in the surrounding area, and a distribution groove 6 is provided around the wall 3a to connect the openings of the water injection holes 5, 5... with each other. A diffusion ridge 7 is formed therein. The diffusion protrusion 7 is formed directly below the water supply port 4, and has an oval shape that is slightly smaller than the bottom wall 3a of the water supply chamber 3 in plan view. On both sides of the bottom wall 3a of the water supply chamber 3, there are inflow holes 2 for the rim water passage.
a, 2a are drilled. The rim water passage (not shown) is formed along the periphery of the front opening of the toilet bowl 2, and has a plurality of water injection holes for cleaning the toilet bowl.

The cleaning water collides with the diffusion ridge 7 and diffuses around its entire circumference, and this diffused water is reflected on the peripheral wall (for example, the inner inner wall 3b) of the water supply chamber 3 and collected into the distribution groove 6. The cleaning water collected in the distribution groove 6 flows through the water injection holes 5, 5...
It flows out from ... and cleans the standing wall part of the toilet bowl 2, and is guided into the rim passageway through the rim passageway inflow holes 2a, 2a and flows out from the water injection hole to wash the drip receiving part of the toilet bowl 2, etc. .

In the conventional cleaning water distribution structure, when cleaning water at a predetermined water pressure is supplied, cleaning water is distributed at a constant rate to all the water injection holes 5, 5... and the rim water passage inlet holes 2a, 2a. Although it distributes the water and cleans the toilet bowl 2 uniformly, when the water supply pressure of cleaning water is low, the distribution ratio is not constant and the toilet bowl 2
A problem has arisen in that the left and right sides of the standing wall and the hanging portions are not sufficiently cleaned. The reason is that the low-pressure cleaning water that collided with the diffusion ridge 7
This is because, due to the low dynamic pressure, it is not possible to diffuse vigorously all around the circumference, but only flows down guided by the surface of the diffusion ridge 7. Therefore, looking at the distribution situation in the water supply chamber 3, cleaning water is not sufficiently supplied to the left and right sides of the water supply chamber 3, which are far from the position directly below the water supply, and the water injection holes 5, 5...and the amount of washing water injected from the water injection holes in the rim passageway is reduced.

The means adopted by the present invention to solve the above problems is that a water supply port leading to the water supply chamber above the toilet bowl is bored on the top surface of the urinal body, a water supply pipe is connected to the water supply port, and the water supply chamber is connected to the water supply port. A plurality of water injection holes for flushing the toilet bowl are drilled around the bottom wall, and inlet holes for the rim water passage are bored on both sides of the front side of the bottom wall. A urinal in which a diffusion ridge is formed around which a distribution groove is connected to the water supply chamber, and a space for water diffusion is formed between the diffusion ridge and the distribution groove and the water outlet of the water supply pipe. A water reservoir surrounded by the diffusion ridge is formed in the bottom wall of the bottom wall directly below the water supply port, and the diffusion ridge has a portion closer to the rim waterway inflow hole that is lower than other portions. This is a flush water distribution structure in a urinal, characterized in that:

ため、洗浄水が確実に導かれることになる。
When cleaning water with low water supply pressure is supplied from the water supply pipe to the water supply chamber, the cleaning water is stored in the water reservoir, then overflows from the entire area of the diffusion ridge and is distributed to the distribution groove, distributing all the water. Wash water flows into the toilet bowl through the hole and the inlet hole for the rim waterway. In particular, since the inflow hole for the rim water passage is close to the lower part of the diffusion ridge, the cleaning water is reliably introduced.

Adjust the inclination angle θ (θ=30
-45°) is extended. The shape of the diffusion protrusion 8 in plan view is such that the shape of the upper inner circumferential edge 8c and the shape of the bottom outer circumferential edge 8d have a substantially similar relationship, so that the amount of washing water overflowing the flat portion 8a'' is smaller than the flat portion 8a. It is made to be uniform over the whole area. Further, the diffusion protrusion 8 is located at the front portion 8a', 8.
a' is lower than the flat part 8a'', and the front part 8a',
The water overflows from 8a' and flows into the rim waterway inflow holes 2a, 2a.
A predetermined amount of washing water is distributed and supplied to the washing water. The water storage portion 9 includes the diffusion ridge portion 8 and the front wall 3c.
The depth dimension H 1 is set to be approximately 15 to 25 mm, and the indoor height dimension H 2 from the bottom surface 9a to the water supply indoor ceiling surface 3d is set to be approximately 40 to 60 mm. A spud 10a of a water supply pipe 10 is allowed to escape into the water reservoir 9. A water diffusion space S is provided between the flat portion 8a″ of the diffusion ridge, the distribution groove 6, and the water outlet 10b of the water supply pipe 10.

When the cleaning water is supplied, the cleaning water is temporarily stored in the water storage section 9 and is distributed to the front portions 8a', 8 of the diffusion ridge 8.
a' and distributed to the rim flow channel inflow holes 2a, 2a, and also overflows from the entire area of the flat part 8a'' of the diffusion ridge 8, thereby being distributed over the entire area of the distribution groove 6, and all The water is injected into the toilet bowl 2 from the water injection holes 5, 5, . When cleaning water with high water pressure (for example, static pressure during flow is 1.0 Kg/cm 2 or more) is supplied to the water supply chamber 3 from front part 8
a', 8a' and also overflows into the distribution groove 6 from the entire area of the flat part 8a'' of the diffusion ridge 8, and the remainder of the cleaning water collides with the cleaning water stored in the water reservoir 9. After being diffused into the water diffusion space S, it is reflected on the peripheral wall of the water supply chamber 3 and distributed into the distribution groove 6. Due to the above-mentioned overflow and reflection distribution, the inflow holes 2a, 2 for the rim water passageway
The cleaning water dispersed over the entire area of the toilet bowl 2 and the distribution groove 6 is injected into the toilet bowl 2 from all the water injection holes 5, 5... and the water injection holes of the rim passageway, and is sprayed over the entire cleaning surface of the toilet bowl 2. Wash thoroughly.
