Description

[Detailed description of the invention] "Purpose of the invention" (Field of industrial application) The present invention relates to a structure for guiding flushing water in a Japanese-style simple flush toilet.

(Prior Art) FIGS. 3 to 5 show a conventional simple flush Japanese-style toilet 1, in which FIG. 3 is a plan view, FIG. 4 is a sectional view taken along the line X-X in FIG. 3, and FIG. FIG. 5 is a sectional view taken along the line Y--Y in FIG. 3. The Japanese-style simple flush toilet 1 is installed in areas where public sewage facilities are underdeveloped, and is equipped with an underground toilet tank (not shown). Since the toilet tank has a capacity limit, the toilet bowl 1a for the toilet tank is
It is not possible to increase the amount of water used to flush out the filth, etc. inside the toilet bowl, and the key to simple flushing is how to keep the amount of water used to flush out the filth and clean the inside of the toilet bowl 1a (hereinafter simply referred to as cleaning water) to a small amount. This was one of the important issues in the Japanese-style toilet bowl 1.

Below, the structure for guiding flushing water in the conventional Japanese-style toilet bowl 1 (hereinafter referred to as conventional water-inducing structure) will be explained. In addition, in the following explanation, the discharge port 9 of the toilet bowl 1a
Based on this, the side where the Kanakakure part 2 is provided (the left side in Figures 3 and 4) is called the (front) of the Japanese-style toilet bowl 1, and the opposite side (the right side in Figures 3 and 4) is called the (front) of the Japanese-style toilet bowl 1. (after). As shown in Figure 4,
A water supply chamber 3 is formed in the front part of the Japanese-style toilet bowl 1 so as to bulge further forward than the gold cover part 2. A water pipe 6 that connects to a low tank or a high tank (not shown) is connected to the water supply chamber 3, so that approximately two wash water channels are formed from the water supply chamber 3 toward the toilet bowl 1a. It's summery. The first wash water flow path is provided on the inner surface of the gold cover part 2. In other words, a downward water discharge step 7 is formed on the inner surface of the gold cover part 2, and about 10 cleaning holes 4a each having a diameter of 3 mm are bored in a row on the downward surface of the water discharge step 7. There is. Therefore, the water supplied into the water supply chamber 3 directly flows into the toilet bowl 1a from the respective cleaning holes 4a, 4a, and washes the inside of the toilet bowl 1a from the front side to the rear side. . On the other hand, the second flush water flow path is provided in a rim 8 (see FIG. 3) provided at the upper peripheral edge of the toilet bowl 1a. That is, a water-inducing stepped portion 5 (see FIG. 5) is formed along the rim 8 on the inner surface of the toilet bowl 1a. Further, the water supply chamber 3 is branched into two parts inside the Kanakakure part 2, as shown by broken lines in FIG.
Water outlet holes 4b, 4b are bored at each branch end. As shown in FIG. 4, the water outlet holes 4b are located on both sides of the connection part where the Kanakakure part 2 rises from the rim 8, and are directed toward the rear side of the toilet bowl with respect to the water induction step part 5. ing. Therefore, the cleaning water discharged from the water supply chamber 3 through the branch passages and from the water outlet holes 4b, 4b is guided to the water induction stage 5 and flows into the toilet bowl 1.
The toilet bowl 1 gradually moves up while reaching the rear confluence part 5a of
It starts to flow down into a.

(Problems to be solved by the invention) Conventional water induction structures have an area between the first wash water flow path and the second wash water flow path where the wash water does not reach and cannot be washed (see Figure 4). ) was applied.
Naturally, if such non-cleanable areas are not cleaned frequently, they will become sloppy due to urine stains and the like, and may also emit a foul odor. However, even if such an area that cannot be washed is to be cleaned, the capacity of the toilet tank is limited as described above, and it is not enough to use water unnecessarily.

The present invention was developed in view of the above-mentioned circumstances, and has a novel flushing water guiding structure ( The purpose of this invention is to provide a water-inducing structure (hereinafter referred to as the proposed water-inducing structure).

``Structure of the invention'' (Means for solving the problems) The gist of the water-inducing structure of the present invention is that the toilet bowl is placed along the rim at the connecting portions on both sides, where the golden parts rise from the rim of the upper periphery of the toilet bowl. A simple water discharge hole is provided facing a water induction step provided around the inner surface, and a water discharge step is provided with a plurality of cleaning holes downwardly provided in the inner surface of the gold cover part. In the flushing water guide structure of the flush-type Japanese-style toilet bowl, a water sprinkling step is provided on the inner surface of the metal cover part so as to face the water sprinkling step, and the water sprinkling step is provided on the inner circumferential surface of the toilet bowl. It is continuous with the water induction step.

(Function) The water sprinkling stage provided on the inner surface of the gold cover part is arranged to face the water discharging stage in which the cleaning hole is formed. Therefore, the water flowing out from each washing hole of the water sprinkling stage hits the water sprinkling stage and is spread out in the width direction of the water sprinkling stage. The inside of the toilet bowl connected to the toilet bowl will be cleaned. In addition, since the water sprinkling step is continuous with the water-inducing step provided around the upper circumference of the toilet bowl, this results in a configuration in which the entire circumference of the toilet bowl is surrounded by the step. Water will flow down from all parts of the step. In other words, it goes without saying that the water flowing out from the cleaning hole of the water discharge step section will clean the conventionally unwashable area, and even the water discharged from the water outlet will clean the area that cannot be washed. It has the potential to be guided as it is possible. In this way, the water induction structure of the present invention is different from the conventional water induction structure, which forms two separate and independent washing water channels, in that it forms one comprehensive washing system for the toilet bowl, and each By synergistically interacting the water supplies, the entire inner surface of the toilet bowl can be thoroughly and efficiently washed with a small amount of water.

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

FIG. 1 is a side sectional view showing a simple flush Japanese-style toilet equipped with the water-inducing structure of the present invention, and is drawn for easy comparison with the conventional water-inducing structure shown in FIG. 4.

The most distinctive feature of the proposed water-inducing structure is the water sprinkling step section 10 provided on the inner surface of the Kanagakure section 2, and the rest of the structure is almost the same as the conventional water-inducing structure (see Figure 4). . That is, a downwardly directed water discharge step 7 is provided on the inner surface of the metal cover part 2, and a plurality of cleaning holes 4a are bored in the water discharge step 7. In addition, a water induction step 5 is provided on the inner surface of the toilet bowl 1a along a rim 8 provided on the upper peripheral edge thereof, and a water outlet 4b is provided toward the rear side of the toilet of the water induction step 5. is drilled.

The water sprinkling step portion 10 is provided facing upward so as to face the water spray step portion 7. In this embodiment, the projecting length of the water sprinkling stage portion 10 was approximately 20 mm.
Further, the water sprinkling step portion 10 is flush with and continuous with the water induction step portion 5 provided around the inner periphery of the toilet bowl 1a. That is,
The toilet bowl 1a has a stepped portion formed all around its upper circumference.

By the way, in a Japanese-style simple flush toilet, the discharge port 9 is located slightly toward the rear of the center of the toilet bowl 1a, but the surface of the bowl around the discharge port 9 naturally gets dirty easily, and is therefore an important point. It is necessary to clean it properly. Therefore, in this embodiment, the following two measures were taken.

(1) The number of cleaning holes 4a drilled in the water discharge step 7 on the inner surface of the Kanakakure part 2 is shown by the broken line in Fig. 2, and as indicated by the symbol, the number of cleaning holes 4a is half that of the conventional water-inducing structure. reduced to pieces.

(2) Water sprinkling stage section 10 located directly below the water outlet 4b
A water retention slope as shown in FIG. 2 was provided on the stepped surface of the continuous portion between the water-inducing step portion 5 and the water-inducing step portion 5.

By taking the measures in (1) above, the cleaning hole 4a
The amount of water flowing out from each part is suppressed, and the amount of water discharged from the water outlet 4b toward the water induction step 5 increases accordingly, and most of the water guided to the pot surface around the outlet 9 loses its momentum. It will flow without being taken away. This measure is brought about by providing the water sprinkling step section 10, which is the main component of the water induction structure of the present invention. In other words, if we similarly reduce the number of cleaning holes 4a in the water discharge step 7 in the Japanese-style toilet bowl 1 (see Fig. 4) with the conventional water induction structure, each cleaning hole 4a, 4a, . . . The water flowing out forms streaks, creating areas between each streak that cannot be cleaned. However, in the water induction structure of the present invention, since the water flowing out from the cleaning hole 4a is spread out in the width direction by the water sprinkling step portion 10, no area cannot be cleaned. In this embodiment, the water flowing down from the water sprinkling step 10 is ensured to spread over the entire surface of the inner surface of the toilet bowl 1a, and is also prevented from forming streaks while flowing down from the respective cleaning holes 4a, 4a, . . . to the water sprinkling step 10. In order to achieve this, the drilling conditions of each cleaning hole 4a were set as follows. That is, as shown in FIG. 2, the center-side drilling pitch (distance) was approximately 50 mm, and the side drilling pitch (distance) was approximately 90 mm. In addition, the cleaning hole 4a is oriented perpendicularly to the water induction step 10 as shown in FIG.
A is tilted approximately 45 degrees to the rear of the toilet.

By taking the measure (2) above, it becomes possible to divert the amount of water flowing out of the cleaning hole 4a that does not flow down from above the water sprinkling stage part 10 to the water induction stage part side. Of course, even if such a measure is taken, the overflow of water from the continuous portion of the water sprinkling stage section 10 and the water induction stage section 5 will not be prevented, and therefore, the conventional non-washable area (as shown in Fig. 5) will not be prevented. There is nothing that can be done about the shaded area).

In this way, the washing water flowing onto the pot surface around the discharge port 9 does not lose its force and cleanly washes away the pot surface. In this way, the configuration and shape of the water-inducing structure of the present invention can be changed as appropriate depending on the embodiment.

"Effects of the invention" As is clear from the above explanation, according to the flush water guiding structure of the simple flush Japanese-style toilet bowl according to the present invention, there is no area that cannot be washed, and the entire inner surface of the toilet bowl is thoroughly cleaned. be able to. Therefore, the inner surface of the toilet bowl does not flatten or create a bad odor, and cleaning that requires a large amount of water does not have to be carried out frequently. In addition, since all of the washing water can be used efficiently, the amount of water used can be reduced to the limit, and the number of times the toilet tank has to be pumped can be reduced as much as possible. There is.
