Description

[Detailed description of the invention] "Purpose of the invention" (Field of industrial application) This invention is a novel method for urinals that can spray flushing water evenly over the entire inner surface of the toilet bowl. It's about structure.

(Conventional Urinal) Fig. 3 is a front view of a conventional wall-mounted stall urinal, Fig. 4 is a sectional view taken along line A-A in Fig. 3, and Fig. 5 is a sectional view taken along line A-A in Fig. 3. FIG. As shown in FIG. 4, the urinal is provided with a water supply chamber 3 on the upper part of the toilet bowl 2, and a water supply port 3a communicating with the water supply chamber 3 on the upper surface of the urinal main body 1.
is drilled. Water supply chamber 3 as shown in Figure 5
The internal shape of the water supply chamber 3 is an oblong shape.
A plurality of water injection holes 4 (see FIG. 4) facing the toilet bowl 2 are bored in the periphery of the bottom wall 3b. Also,
At both front sides of the water supply chamber 3, there are inlet holes 2 for a rim water passage formed along the front opening periphery of the toilet bowl 2.
a, 2a are drilled. In addition, in the same figure, the area directly below the water supply port 3a is indicated by a chain double-dashed line. When the flushing start button 5 shown in FIG. 3 is pressed in the urinal constructed in this manner, water from the flush valve 6 flows into the water supply chamber 3 above the toilet bowl 2 from the water supply port 3a as shown in FIG. and each water injection hole 4, 4, of the water supply chamber 3.
... flows into the toilet bowl 2, and flows from the inflow hole 2a of the water supply chamber 3 (see Figure 5) through the rim passageway, and from the rim hole 2b provided at the bottom of the urinal body 1 to the discharge port 1a. Once upon a time, it began to leak.

(Problem to be solved by the invention) Conventionally, as shown in Fig. 4, the water supply port 3
The water flowing from a into the water supply chamber 3 above the toilet bowl 2 is
As shown by the arrow, it strongly collides with the rear wall 3c of the water supply chamber 3, and most of it is reflected. When viewed from above, the trajectory of water reflection is as shown by the arrow in FIG. In other words, water flowing into the water supply chamber 3 from the water supply port 3a is preferentially supplied from the water injection hole 4 located far from directly below the water supply port 3a.
It has a drawback that water is not easily supplied to the water injection hole 4 that allows water to flow down to the front area of the toilet bowl 2 (the area indicated by hatching in FIG. 3). Furthermore, since the water flowing down from the water injection hole 4 is in a turbulent state within the water supply chamber 3 as described above, it does not flow along the inner surface of the toilet bowl 2 as shown by the arrow in FIG. For this reason, the front part of the toilet bowl 2, which is the most visually visible and dirtiest part of the urinal, is always the dirtiest.

The present invention was developed in view of the above-mentioned circumstances, and is a novel small device that can prevent uneven cleaning by discharging toilet bowl cleaning water evenly over the entire inner surface of the toilet bowl. The purpose of the present invention is to provide a toilet bowl wash water equal distribution structure (hereinafter referred to as the "proposed equal distribution structure").

``Structure of the invention'' (Means for solving problems) The gist of the equal distribution structure of the present invention 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, and the water supply chamber In a urinal having a plurality of water injection holes for flushing water around the bottom wall of the urinal, a diffusion hill is formed on the bottom wall of the water supply chamber in a raised area directly below the water supply port, and the diffusion hill is formed on the bottom wall of the water supply chamber. The surrounding area is a water storage groove that interconnects the openings of the water injection holes.

(Function) A diffusion hill is formed on the bottom wall of the water supply chamber at a portion directly below the water supply port, and the area around the diffusion hill is a water storage groove that interconnects each opening of the water injection hole. . Therefore, when water is supplied into the water supply chamber from the water supply port, the water collides with the diffusion hill and diffuses around the entire circumference thereof. The diffused water flows into the water storage groove, and at the same time is guided to the opening of each water injection hole, and flows down from the water injection hole toward the inside of the toilet bowl. Additionally, once the water has flowed into the water storage groove, it will remain in the water storage groove until the water surface level rises and exceeds the depth of the water storage groove. Keep it level across the entire area. In other words, the amount of water supplied to each water injection hole is the same, and the toilet bowl flushing water flowing down from all the water injection holes is also approximately the same amount of water. Moreover, the fact that the water once stagnates in the water storage groove as described above and then flows down from the water injection hole again leads to rectification, and the flowing water flows along the inner surface of the toilet bowl.

(Example) The present invention will be described below based on drawings showing examples thereof.

FIG. 1 is a plan view showing the proposed equal distribution structure with a part of the urinal cut away, and is drawn for easy comparison with FIG. 5. As shown in the figure, the most distinctive feature of the equal distribution structure of the present invention is that a diffusion hill 8 is formed on the bottom wall 3b of the water supply chamber 3 in a raised manner. The rest of the structure is almost the same as a conventional urinal (see Figs. 3 to 5), namely, a water supply chamber 3 is provided at the top of the toilet bowl 2, and
A water supply port 3a communicating with the water supply chamber 3 is bored in the upper surface of the urinal main body 1. Further, a plurality of water injection holes 4 facing the toilet bowl 2 are bored in the peripheral part of the bottom wall 3b of the water supply chamber 3.

As shown in FIG. 1, the diffusion hill 8 is connected to the water supply chamber 3.
On the bottom wall 3b of the water supply chamber 3, a raised portion is formed directly below the water supply port 3a (indicated by the two-dot chain line), and its shape in plan view is an elongated circle that is one size smaller than the bottom wall 3b of the water supply chamber 3. . The periphery of the diffusion hill 8 is an annular water storage groove 7. In other words, the water storage groove 7
The openings of a plurality of water injection holes 4 bored in the periphery of the water supply chamber 3 are connected in series.
The detailed dimensions of the water storage groove 7 in this embodiment are a maximum width of 25 mm and a maximum depth of 20 mm.

FIG. 2 is an enlarged side sectional view showing the equal distribution structure of the present invention. As shown in the figure, the upper surface of the diffusion hill 8 is provided with a slope that descends toward the rear wall 3c of the water supply chamber 3, and is also provided with a gentle convex radius. Although not shown in the drawings, this upper surface convex radius is also provided in the longitudinal direction (lateral direction) of the diffusion hill 8. Therefore, the water supplied from the water supply port 3a is
It does not stay on the upper surface of the diffusion hill 8.

Therefore, when water is supplied from the water supply port 3a, the second
As shown by the arrow in the figure, the water collides with the diffusion hill 8 and diffuses all around it, and this diffused water is reflected on the peripheral wall (for example, the rear wall 3c) of the water supply chamber 3 and is all inside the water storage groove 7. be gathered to. Therefore, sufficient toilet bowl washing water for flushing flows into the toilet bowl 2 from all the water injection holes 4. Further, since the water collected in the water storage groove 7 temporarily remains in the water storage groove 7, the turbulent flow caused by diffusion, reflection, etc. as described above is alleviated and the water is rectified. The toilet bowl washing water flowing down from the water injection hole 4 flows along the inner surface of the toilet bowl 2.

(Study of Alternative Embodiments) The equal distribution structure of the present invention is not limited to wall-mounted stall urinals, but can be applied to all types of urinals. Further, the water reservoir groove is not limited to one that connects all the water injection holes in a series, but may be one that divides three to four water injection holes into different small groups that communicate with each other. In this way, the configuration and shape of the equal distribution structure of the present invention can be changed as appropriate depending on the implementation mode.

"Effect of the invention" As is clear from the above explanation, according to the urinal toilet bowl flushing water equal distribution structure according to the present invention, the amount of toilet bowl flushing water flowing out from the injection holes is approximately the same. It has excellent advantages such as being able to clean the entire inner surface of the toilet bowl without causing uneven cleaning.
