Description

  The present invention relates to a urinal.

  Patent document 1 is disclosing the conventional urinal. This urinal includes a toilet body having a toilet bowl and a sprayer that sprays a liquid deodorant into the toilet bowl. In this urinal, since the sprayer sprays the liquid deodorant toward the toilet bowl, the toilet bowl can be filled with the atomized liquid deodorant. For this reason, deodorization of a urinal can be performed reliably.

JP-A-7-317122

  However, in the urinal of Patent Document 1, the liquid deodorant sprayed by the sprayer can temporarily deodorize the odor, but the urine that causes the odor is actively discharged from the toilet bowl. I can't. For this reason, with the passage of time, odor may be generated from the urine remaining on the surface of the toilet bowl, or urine stones may be formed on the surface of the toilet bowl. That is, urine does not generate odor immediately after excretion, but urine generates odor by ammonia generated by decomposition of components in urine by the action of bacteria. For this reason, if urine remains on the surface of the toilet bowl, an odor is generated over time. Further, when the pH rises due to the generation of ammonia, calcium ions and the like in urine are precipitated as carbonates and phosphates to form uroliths. For this reason, if urine remains on the surface of the toilet bowl, urine stones are formed on the surface of the toilet bowl over time. Furthermore, because urine stone is porous, it becomes a hotbed of various bacteria and organic matter, and emits a more intense odor.

  There is a flush-type urinal that allows urine to be discharged from the toilet bowl by flowing flush water over the surface of the toilet bowl, thereby preventing the generation of odors and urine stones. Consume ~ 3L of wash water.

  This invention is made | formed in view of the said conventional situation, Comprising: It is set as the problem which should be solved to provide the urinal which can prevent generation | occurrence | production of an odor and a urine stone with a small amount of water.

The urinal of the present invention is a toilet body having a toilet bowl with a discharge port at the lower end,
A sprayer for spraying water toward the surface of the toilet bowl,
In addition to the sprayer, a water supply device for supplying water to the toilet bowl is not provided.

  This urinal sprays water on the surface of the toilet bowl with a sprayer, so a small amount of water can wet the necessary area of the surface of the toilet bowl, preventing urine from remaining on the surface of the toilet bowl. can do. For this reason, in this urinal, it is possible to prevent urine components from being decomposed by the action of bacteria on the surface of the stool portion and ammonia being generated. Moreover, since ammonia is not produced | generated, the raise of the pH of the surface of a toilet bowl part can also be prevented.

  Therefore, the urinal of the present invention can prevent the generation of odor and urine stone with a small amount of water.

  A drain trap provided continuously with the discharge port, insoluble in water, having a specific gravity lighter than that of urine, and injected with a seal solution that forms a seal layer above the stored urine may be provided. In this case, the drainage trap provided in a normal flush toilet urinal prevents the downstream odor from flowing back to the upstream toilet bowl side, whereas this drainage trap is a sealing liquid. The sealing layer formed by can prevent the downstream odor from flowing back to the toilet bowl side. For this reason, this drain trap does not need to store water and can save water. Therefore, this drain trap is suitable for a urinal that sprays a small amount of water on the surface of the toilet bowl with a sprayer to prevent urine from remaining on the surface of the toilet bowl. In addition, the amount of water flowing into the drainage trap from the toilet bowl is small, and the momentum is weak, so the sealing liquid in the drain trap is difficult to flow out, and the odor downstream of the drain trap moves to the upstream toilet bowl side. Backflow can be reliably prevented for a long period of time.

  The sprayer may spray regularly so that the surface of the toilet bowl is always wet. In this case, since the surface of the toilet bowl is always kept wet, it can be reliably prevented that the surface of the toilet bowl is dried and urine is fixed. For this reason, even if the amount of water sprayed from the sprayer is small, it is possible to reliably prevent urine from remaining on the surface of the toilet bowl, and to prevent the generation of odors and urine stones.

It is sectional drawing which shows the urinal of an Example. It is a front view which shows the urinal of an Example.

  An embodiment embodying the urinal of the present invention will be described with reference to the drawings.

<Example>
The urinal of an Example is provided with the toilet bowl main body 10 which has the toilet bowl part 11, and the three sprayers 50 provided in the surface of the toilet bowl part 11, as shown in FIG.1 and FIG.2. The toilet body 10 is locked to a wall surface and fixed. The toilet body 10 is provided with a circular outlet 12 at the lower end of the toilet bowl 11. The toilet body 10 has a cylindrical storage container 20 that is continuous with the discharge port 12, opens at the top, and has a bottom. The storage container 20 has a connecting tube 21 extending from the lower end. The storage container 20 is connected to a drain pipe 30 drawn to the wall surface via a connecting pipe 21.

  The storage container 20 detachably stores a drain trap 40 formed in a cartridge form. The drain trap 40 has an inflow port 41 </ b> A at the center of the upper surface portion 41 and an outflow port 42 </ b> A at the corner of the bottom surface portion 42. The drain trap 40 has a storage portion 43 that temporarily stores urine and the like flowing in from the inflow port 41A, and an outflow path 44 through which urine and the like overflowing from the storage portion 43 flow down. The lower end of the outflow channel 44 communicates with the outflow port 42A. The storage portion 43 is partitioned into a first chamber 43A on the inflow port 41A side and a second chamber 43B on the outflow port 42A side by a partition wall 45 hanging from the upper surface portion 41 of the drain trap 40. The first chamber 43A and the second chamber 43B communicate below the lower end of the partition wall 45. The first chamber 43A is insoluble in water, has a specific gravity lighter than that of urine, and is injected with a sealing liquid that forms a sealing layer 46 above the stored urine.

  As described above, the drain trap 40 can prevent the downstream odor from flowing backward to the toilet bowl 11 side by the sealing layer 46 formed by the sealing liquid. For this reason, the drain trap 40 does not need to store a large amount of water, and can save water. Therefore, the drain trap 40 is suitable for a urinal that sprays a small amount of water on the surface of the toilet bowl 11 by the sprayer 50 to prevent urine from remaining on the surface of the toilet bowl 11.

  In a state where the drain trap 40 is stored in the storage container 20, the outlet 12 of the toilet bowl 11, the upper end opening of the storage container 20, and the upper end periphery of the drain trap 40 are continuous in a watertight manner. For this reason, the urine etc. which flowed down the surface of the toilet bowl part 11 flows through the surface of the upper surface part 41 of the drain trap 40, and flows in into the 1st chamber 43A of the drain trap 40 from the inflow port 41A formed in the center part. As described above, the urinal is provided with the drain trap 40 provided continuously to the discharge port 12.

  The sprayer 50 is attached to the center of the upper edge 11A on the surface of the toilet bowl 11 and the upper part of the left and right edges 11B, respectively. These sprayers 50 have a plurality of spouts 51 for spraying water toward the surface of the toilet bowl 11. The spout 51 is directed in various directions so that water can be sprayed over a wide range of the surface of the toilet bowl 11. These sprayers 50 communicate with a water supply channel (not shown). The water supply path is provided with a valve device having an on-off valve for opening and closing the water supply path, and the upstream end communicates with a water supply source having a water supply pressure.

  The valve device provided in the water supply path has a human body detection sensor that detects a user of the urinal. When the human body detection sensor detects that the user using the urinal has left the set distance from the front of the toilet body 10, the valve device opens the on-off valve. Thereby, the sprayer 50 sprays water toward the surface of the toilet bowl 11. At this time, the amount of water sprayed by the sprayer 50 may be so small that the surface of the toilet bowl 11 is wetted so that urine flows down the surface of the toilet bowl 11 and flows into the drain trap 40.

  Thus, this urinal can wet the required range of the surface of the toilet bowl 11 with a small amount of water, and can prevent urine from remaining on the surface of the toilet bowl 11. For this reason, in this urinal, it is possible to prevent the urine components from being decomposed by the action of bacteria on the surface of the stool part 11 to generate ammonia. Moreover, since ammonia is not produced | generated, the raise of the pH of the surface of the toilet bowl part 11 can also be prevented.

  Therefore, the urinal of the embodiment can prevent the generation of odor and urine stone with a small amount of water.

  In addition, the valve device provided with the water supply channel periodically opens the opening / closing valve at a set time interval when the time during which the human body detection sensor does not detect the user of the urinal exceeds the set time. At this time, the amount of water sprayed by the sprayer 50 may be small enough to wet the surface of the toilet bowl 11. The time interval for opening the on-off valve is set for the purpose of keeping the surface of the toilet bowl 11 always wet. For this reason, this time interval can be changed according to the environment where the urinal is installed, such as every site where the urinal is installed and every season.

  Thus, since this urinal is always kept in a wet state, the surface of the toilet bowl 11 can be reliably prevented from drying and the urine sticking. it can. For this reason, even if a small amount of water is sprayed from the sprayer 50, it is possible to reliably prevent urine from remaining on the surface of the toilet bowl 11, and to prevent generation of odors and urine stones.

  In addition, since this urinal has a small amount of water flowing into the drain trap 40 from the toilet bowl 11 and its momentum is weak, the sealing liquid in the drain trap 40 hardly flows out, and the odor on the downstream side of the drain trap 40 Can be reliably prevented for a long time from flowing back to the toilet bowl 11 side on the upstream side.

The present invention is not limited to the embodiments described with reference to the above description and drawings. For example, the following embodiments are also included in the technical scope of the present invention.
(1) In the embodiment, the urinal was provided with a drain trap, but it may be a urinal without a drain trap. Further, the drain trap may have another form.
(2) In the embodiment, the detachable cartridge-type drain trap is provided, but the drain trap may be formed entirely or partly with the urinal.
(3) In the embodiment, three sprayers were provided. However, the sprayer only needs to be able to spray water on the necessary range of the surface of the toilet bowl. It may be changed.
(4) In the embodiment, the valve device provided in the middle of the water supply channel communicating with the sprayer has a human body detection sensor, and the open / close valve of the valve device is opened and closed by detection of the user of the human body detection sensor. However, it may have a manual button for manually opening and closing the on-off valve without having the human body detection sensor. In this case, after the user of the urinal uses the manual button, the open / close valve is opened to spray water on the surface of the toilet bowl.
