Description

  The present invention relates to a urinal, and more particularly, to a urinal that discharges in response to urination.

Normally, a urinal that receives and discharges urine is provided with a water discharge part that supplies wash water and cleans the bowl surface, and by manual operation such as a push button by the user automatically or by a user, Washing water is supplied to the bowl surface from the water discharger to wash the bowl surface.
Here, the wash water that has washed the bowl surface of the urinal flows out from the drain port provided below the bowl surface, passes through the water trap portion of the drain trap provided on the downstream side of the drain port, and downstream from this After flowing through the connecting pipe on the side, it flows into the drain pipe outside the urinal and is discharged outside.
In addition, a normal drain trap is provided below the urinal and has a descending pipe that guides the wash water flowing out from the drain port downward, and a rise pipe that is provided downstream of this and guides the wash water upward. It consists of a substantially U-shaped pipe with a path. In addition, the drainage pipe outside the urinal is connected to the drainage trap by a connection pipe, and the wash water that has passed through the drainage trap rising pipe flows into the drainage pipe via the connection pipe. ing.

  In such a urinal, in order to perform cleaning of the bowl surface and / or the inside of the drainage pipe every time it is used or at a predetermined timing, the bowl surface and the drain pipe are cleaned and discharged by supplying water. Although the flushing water flows through the bowl surface, drain trap, connecting pipe, and drain pipe in sequence, the urinal is cleaned, but the drainage trap is conventionally used because of the drainage path of flush water from the urinal. Urine stones are attached to the connecting pipe, or the connection between the downstream end of the connecting pipe and the drainage pipe outside the urinal, etc. due to urine denatured by the action of microorganisms, and it is more likely to accumulate. There was a problem.

Among these, the urine stone adhering to the drain trap can be removed to some extent by performing normal cleaning in which a cleaning brush is inserted into the drain trap for cleaning.
However, for urinary stones that adhere to the connection line connected to the rear side (downstream side) of the drain trap, the connection part between this connection line and the drain line outside the urinal, etc. Because it is also a part that is difficult to clean by inserting a cleaning tool such as a brush into these conduits, the attached urine stone gradually grows and the deposition amount increases, finally There is a problem that the connection pipe and the drain pipe may be blocked.

The places where such urine stones adhere and accumulate are places where it is difficult to perform normal cleaning by inserting a cleaning tool as described above, and in order to remove such urine stones every predetermined period. Once the urinal is removed from the drain line outside the urinal, the urine stone is dissolved with a chemical, a rotating grindstone tool is used to wear out the urine stone, or it is removed by high-pressure washing. It is necessary to do.
However, such a removal process is not only costly, but also makes it impossible to use the toilet during the period of the maintenance action, which is a large-scale processing operation and cannot be easily performed.

For example, in the conventional urinal described in Patent Document 1, a discharge path to which the upstream side of the drain pipe outside the urinal is connected is provided on the downstream side of the drain trap, and the discharge path and the outside of the bowl portion are connected to each other. A cleaning water supply port is provided in the partition wall, and a supply pipe is connected to the supply port from the outside on the back side of the bowl portion. Then, the wash water in the supply pipe is directly supplied from the supply port into the discharge path without passing through the bowl surface of the urinal and the drain trap, so that the discharge path on the downstream side of the drain trap is It is designed to be washed.
Moreover, in the conventional urinal described in Patent Document 2, an opening into which a cleaning tool can be inserted is formed on the rear bottom surface of the bowl portion located above the outflow portion of the drain trap, and a short cylinder is formed in this opening. The upper socket is fixed, and the obturator is detachably attached to the socket. The projection surface of the opening cross-section projected onto the drain trap along the central axis is formed at the top of the drain trap outlet, and the cleaning tool can be inserted from the opening by removing the obturator. It is possible to clean the vicinity of the outflow portion on the downstream side of the drain trap.
Furthermore, in the conventional urinal described in Patent Document 3, a through-hole into which a high-pressure hose for washing water feeding can be inserted is formed on the rear bottom surface of the bowl portion located above the outflow portion of the drain trap. . The projection surface of the through hole's opening cross section projected onto the drain trap along the central axis is formed at the top of the drain trap's outflow part, and a high-pressure hose for supplying cleaning water is inserted into the through hole for cleaning. By ejecting high-pressure washing water from the tip of the high-pressure hose for water supply, the drain pipe connected to the outside of the rear side (downstream side) of the urinal can be washed without removing the urinal. It has become.

In the urinal 1, after the user urinates into the bowl portion 4, the water discharge device 6 discharges the cleaning water supplied from the water supply pipe 6 a to the bowl surface 4 a. The washing water discharged from the water discharging device 6 flows while washing the bowl surface 4a from the upper side toward the lower drainage port 8.
Then, the washing water that has flowed into the descending conduit 12 of the drain trap 10 from the drain port 8 pushes the urine collected in the drain trap 10 to the downstream ascending conduit 14 and enters the drain chamber 18 from the ascending conduit 14. The wash water that has flowed out flows downstream through the connection passage 20 and drains urine from the connection port 24 into the drainage pipe 16.

Here, as shown in FIG. 3 and FIG. 4, the bowl surface 4 a is washed, flows from the drain port 8 into the descending pipeline 12 of the drain trap 10, is discharged from the ascending pipeline 14, and flows through the connecting passage 20. The maximum water level WL1 of the water W (drainage) is located below the center position H3 of the connection port 24, and the lower edge 26a of the cleaning port 26 is the upper edge of the connection port 24 of the connection passage portion 20. Since it is located above the position H2, the urine drained by the cleaning water W is less likely to get on the cleaning port 26. Therefore, it is possible to prevent urine stones from adhering to the vicinity of the cleaning port 26, and it is possible to prevent the lid 28 from becoming difficult to attach and detach due to the urine stones attached to the cleaning port 26.
In addition, about the urinal 1 by 1st Embodiment of this invention mentioned above, although the form which wash | cleans the bowl surface 4a using the washing water W discharged from the water discharging apparatus 6 was demonstrated, the water discharging apparatus 6 is not provided. In addition, the present invention can be applied to a form of an anhydrous urinal that does not use the washing water W for washing the bowl surface 4a.

Below, the cleaning method in the connection channel | path part 20 and the drain piping 16 of the downstream rather than the drain trap 10 of the urinal 1 by 1st Embodiment of this invention is demonstrated.
First, the cleaner removes the cover 28 attached to the cleaning port 26, inserts a nozzle (not shown) of high-pressure washing water as a cleaning tool into the opened cleaning port 26, and the nozzle (not shown). ) High-pressure washing water is spouted from the tip of).
And the urine stone adhering to the connection channel | path part 20 and the drain piping 16 is removed with a high voltage | pressure washing water, and it extrudes to a downstream side and cleans.
Further, instead of using a high-pressure washing water nozzle (not shown), a medicine may be introduced through the opened cleaning port 26 to dissolve urine stone. Further, the urine stone may be worn by passing a rotating grindstone-like tool for wearing the urine stone.
In this way, the connection passage 20 and the drainage pipe 16 can be easily and reliably cleaned simply by removing the lid 28 from the cleaning port 26 and inserting a nozzle (not shown) of high-pressure washing water or introducing a chemical. Therefore, without removing the urinal 1 from the drain pipe 16, the connection passage 20 downstream of the drain trap 10 can be cleaned, and the cleaning operation can be completed in a short time.
Therefore, even in public toilet spaces where there are many users such as rest areas on expressways, cleaning can be performed in a shorter time than before, so the user uses the urinal 1 to clean the urinal 1 It is possible to keep the time that cannot be kept short.

  According to the urinal 1 according to the first embodiment of the present invention described above, the projection surface S3 obtained by projecting the opening cross section S1 of the cleaning port 26 along the central axis A1 toward the connection passage portion 20 is formed on the connection passage portion 20. Since the bottom surface 20c is formed, the drain trap 10 can be removed without removing the entire urinal 1 from the drain pipe 16 outside the back side of the urinal body 2 when the inside of the drain chamber 18 of the urinal 1 is cleaned. For example, a cleaning tool (not shown) can be removed from the lower region R1 side in the bowl portion 4 by simply removing the lid 28 from the cleaning port 26 in the front side wall portion 22 of the drainage chamber 18 formed on the rear side of the cleaning chamber 26. It is easy to clean the vicinity of the connecting passage portion 20 of the drainage chamber 18 formed on the rear side (downstream side) from the drain trap 10 by a cleaning tool (not shown) inserted into the inner region R2 of the drainage chamber 18. And can be done reliablyTherefore, it is possible to prevent urine stones from adhering and accumulating near the connection passage portion 20 on the rear side (downstream side) of the drain trap 10, and the connection discharged from the drain trap 10 by washing the bowl surface 4 a. Clogging of the drainage of the passage portion 20 can be prevented.

  In addition, according to the urinal 1 according to the present embodiment, the urine stones can be removed by simply removing the lid 28 from the cleaning port 26 in the connection passage portion 20 on the downstream side of the drain trap 10 on which urine stones easily adhere and accumulate. It can be confirmed by simple visual observation whether or not it adheres in the connection passage portion 20.
