Description

[Detailed explanation of the invention] (Industrial application field) This invention is designed to reduce the amount of washing water from about 2 to 1.
This article relates to a urinal that is useful for water-saving flushing of approximately 200 c.c. and simple flushing of approximately 200 c.c.

(Conventional technology) Cleaning performance of the ball surface The ball surface of the urinals for regular flushing, water saving flushing, and simple flushing urinals has a drain port that also serves as the fitting part of the perforated plate located in the center or on the vertical water surface side. The drainage port is either horizontal or slopes downward toward the rear. (For example, see Japanese Utility Model Application Publication No. 60-53880.) The drainage port is formed in such a way that it flows from around the round-head-shaped perforated plate and under the perforated plate, or it is opened in a disc-shaped perforated plate. The hole has become horizontal. In addition, the perforated plate prevents foreign matter from flowing into the drain, and the cleaning water is used to clean the vertical water surface and the ball surface area from the same surface to the drain, which is the area that is most contaminated by urination. After flowing and cleaning, it flows out to the drain outlet, and the part of the washing water that cannot flow out temporarily fills the ball surface and flows into the drain outlet one after another, washing the drip receiving surface part with a weak flow force. It is something.

Therefore, there is a structural problem in that the drip receiving surface tends to be insufficiently cleaned compared to the other surface, and dirt on the drip receiving surface gradually becomes noticeable.

In order to solve this problem, we formed a rim water passage inside the front edge of the drip receiving surface, and also provided an open water injection hole from the rim passageway toward the drip receiving surface. Some devices are designed to clean the surface. (Refer to the above-mentioned publication) However, dirt still tends to remain on the drip receiving surface between each water injection hole, and this dirt is conspicuous in the form of cleaning spots, such as a radial pattern, especially in public use. Further, the structure is complicated by the presence of the rim passageway and the water injection hole, and there is also the problem that it takes time and effort to mold.

Odor prevention and freezing measures The applicant applied for an odor-proof trap for urinals in 1982.
It was proposed in No. 125156 (Utility Model Publication No. 59-31681).

This deodorizing trap is configured to be deformable into a mode in which it exhibits a water-sealing function and a mode in which it does not exhibit the same function, so that it can seal out odors except during the freezing period when not much odor is generated.

Although this is a useful deodorizing trap, since it is designed to be able to be set into an existing urinal, it is large and cannot be removed and replaced unless it is inserted under the urinal and moved to set it. .

(Problem to be Solved by the Invention) The problem to be solved by the invention is that the drip receiving surface can be cleaned without relying on the rim passageway and water injection hole that cause the above-mentioned inconveniences, and instead of relying on the rear vertical water flow surface. To provide a urinal that is improved so that the drip receiving surface can be thoroughly and effectively cleaned by the washing water flowing down the bowl, has sufficient odor prevention and anti-freezing measures, and allows the trap to be attached and detached from the bowl surface side. There is something to do.

(Means for Solving the Problems) The means taken by the present invention to achieve the above-mentioned problems is to force a strong flow of washing water flowing down from the vertical flowing water surface to the drip receiving surface. The strong current is used to evenly wash the drip receiving surface, and the washing water is guided from the drain to the trap under the perforated plate, so that both the trap and the perforated plate can be removed from the ball surface. This is what I did.

More specifically, the ball surface of the urinal body is connected from the vertical water flow surface on the rear side to the perforated plate mounting surface that slopes downward toward the front, and the washing water return section at the front edge to the downward slope toward the rear. The part connected to the slanted drip receiving surface is shaped like a valley, and the perforated plate is placed in the perforated plate receptacle step at the upper edge of the drainage hole of the perforated plate mounting surface so as to face the front side of the top surface of the perforated plate. A downwardly sloping washing water flow guide surface is removably covered flush with the perforated plate mounting surface, and a drain port is opened in the above-mentioned connected part in communication with the drain hole, and the drain hole is connected to the drain hole. An annular water seal made of a flexible elastic material with a water hole in the center is removably fitted tightly.
The annular groove of the water seal and the annular leg part of the lower surface of the perforated plate inserted in the annular groove form a trap with a water seal depth of approximately 1 cm or more leading from the drain outlet side to the water passage hole side. It is characterized by having a configuration consisting of:

(Function) The perforated plate mounting surface and the cleaning water flow guiding surface on the top surface of the perforated plate, both of which are sloped downward toward the front, flow down along the vertical water surface and transfer all the cleaning water that has washed away dirt from the same surface to the flow force. Direct it to the drip receiving surface,
The drip receptacle surface is cleaned by the flow and the flow returned by hitting the washing water return part, and the drain port allows all the washing water to flow out from the drip receptacle until the end. The entire ball surface including the drip receiving surface is equally cleaned from start to finish. A trap built into the drainage hole that communicates with the drainage hole seals out odors and can be removed from the ball surface in case it freezes.

(Example) An example of the embodiment will be described below with reference to the drawings.

A in the figure is a flush urinal, and this flush urinal A
, the ball surface 2 of the urinal body 1 is continuous from the vertical water flow surface 3 on the rear side toward the front side, and from the perforated plate mounting surface part 2a that is sloped downward and the washing water return part 4 on the front edge to the rear side. The connected portion 2c with the drip receiving surface portion 2b, which is sloped downward, is formed in a valley shape, and the perforated plate 7 is installed in the perforated plate receiving step portion 6 at the upper edge of the drainage hole 5 of the perforated plate mounting surface portion 2a. is removably covered with a washing water flow guiding surface 7a which is sloped downward toward the front side of the perforated plate upper surface and flush with the perforated plate mounting surface part 2a, and a drain port 8 is provided in the above-mentioned coupled part 2c. An annular water seal 9 made of a flexible elastic material is opened in communication with the drainage hole 5 and has a water passage hole 10 in the center thereof, and is removably and tightly fitted into the drainage hole 5. The groove 11 and the annular leg part 12 on the lower surface of the perforated plate 7 interposed in the annular groove 11 form a trap 13 that communicates from the drain port 8 side to the water passage hole 10 side and has a water seal depth of approximately 1 or more. are doing.

The perforated plate mounting surface portion 2a is formed in a downward slope from the water flow surface 3 toward the front drip receiving surface portion 2b so as not to kill the flow of washing water.

The perforated plate 7 has a washing water flow guiding surface 7a on the upper surface slanting downward toward the drip receiving surface 2b on the front side, and the degree of sinking of this washing water flow guiding surface 7a with respect to the perforated plate mounting surface 2a is the same as that of the perforated plate mounting surface 2a. It is desirable to set the height to be slightly lower than the above, so that the wash water flows smoothly from the water flow surface 3 side to the wash water flow guide surface 7a and does not scatter.

The drain port 8 is disposed in the connected part 2c of the perforated plate tray part 6 where there is no shelf part on the side of the drip receiving surface 2b, and this drain port 8 descends from the side of the drip receiving surface 2b toward the drain port 5. It has an inclined guide surface portion 8a,
Washing water is guided to the guiding surface portion 8a and flows out intensively to the drain port 8 from the drip receiving surface portion 2b side. In addition, a perforated plate 7 that also serves as a part of the drain port 8
A rod-shaped object is inserted into the concave notch 8b to form the perforated plate 7.
It is possible to remove it.

The annular water seal 9 in the drain hole 5 is made of a flexible and elastic member, such as rubber, and the collar 14 provided around its circumferential side is brought into close contact with the surface of the drain hole 5, so that the cleaning water can be flushed with the surface of the drain hole 5. This prevents it from flowing between it and the envelope 9. The water sealing depth of the trap 13 formed by the water sealing body 9 and the annular leg portion 12 is approximately 1 cm or more, specifically 1 cm, which is enough to melt the ice by urine temperature even if frozen.
or more than 5cm as specified by the Building Standards Act.

The drain pipe 15 communicating with the water passage hole 10 on the lower side of the water seal body 9 has an annular support portion 16 having a larger diameter than the drain hole 5 at the upper end at its upper end. The water seal body 9 is supported from below by a rib portion 17 provided protruding from the side. Further, an annular packing 18 is interposed between the outer peripheral portion of the support portion 16 outside the drain hole 5 and the lower surface of the urinal body 1 to prevent odor from leaking out.

Fig. 3 shows an embodiment of a flush urinal A, in which the depth of the water seal in the trap 13 is approximately 1 cm.
The cleaning water spouting nozzle 19 is configured to be able to spray a fixed amount of cleaning water (the water spouting nozzle proposed by the applicant in Japanese Utility Model Publication No. 59-38552),
For example, it is suitable for simple washing with a small amount of water of about 200 c.c.

FIG. 4 shows a flush urinal A according to another embodiment, in which the water sealing depth of the trap 13 is 5 cm or more, and the water discharge nozzle (not shown) is of a normal open type configuration, for example. Suitable for main washing where the amount of washing water is about 2, and water saving washing where the amount of washing water is about 1.

Regarding the material, for example, the urinal body 1 is made of ceramic. The perforated plate 7 is made of hard, corrosion-resistant ceramic, plastic, or metal. The drain pipe 15 is made of corrosion-resistant plastic or metal. The packing 18 is an elastic member such as rubber.

(Effect of idea) Therefore, the present invention has the following advantages.

The washing water flowing down the flowing water surface flows down the washing water flow guide surface which is sloped downward from the same flowing water surface toward the front side of the upper surface of the perforated plate, and flows all at once to the drip receiving surface without significantly reducing the flow force. At the same time, the water is returned by the water returning section and flows back to the drip receiving surface, so that not only the flowing water surface but also the entire surface of the ball including the drip receiving surface is equally cleaned, preventing the formation of cleaning spots, making it especially useful for public use. be.

Since the drain port is located in the trough on the front side of the ball surface, the drip receiving surface portion can be continued to be washed until the end of the washing water flowing out from the drain port to the drain hole.

The washing water flow guide surface on the upper surface of the perforated plate is flush with the perforated plate mounting surface and slopes downward toward the front side, so that water splashing does not occur and the flow force is not lost.

A compact trap placed inside the drain hole under the perforated plate seals out odors, preventing unpleasant odors from rising from the drain. Moreover, since the annular water seal is made of a flexible and elastic material, there is no need to worry about damage even if the water inside the trap freezes.
It is also possible to prepare for freezing by removing the water seal from inside the drainage hole where the perforated plate was removed.

The water seal can be freely attached and removed from the ball surface side, making it easy to replace, and since the water passage hole on the outflow side of the trap is located in the center of the water seal, the drainage connected to it can be easily removed. The tube can also be of small diameter.

By combining the above, the cleaning efficiency of the washing water is maximized, and it is also sufficiently odor-proof and anti-freeze, and can be used not only for main washing with a large amount of water, but also for simple washing with a small amount of water. It is extremely useful, and since it does not require a rim passageway or a water injection hole unlike conventional products, it has a simple structure and is easy to mold.
