Description

  The present invention relates to a urinal, and more particularly to a urinal for receiving and discharging urination.

Usually, in urinals that receive and discharge urination, urinary stones attached to a drainage trap that forms sealing water downstream of the drainage port at the bottom of the bowl that forms the bowl surface that receives urination are used for cleaning. It can be removed to a certain extent by performing the usual cleaning in which the brush is inserted into the drainage trap for cleaning.
However, for urinary stones deposited on the connection pipeline connected to the rear side (downstream side) of the drainage trap, the connection between this connection pipeline and the drainage pipeline outside the urinal, etc. Since it is also a part where it is difficult to clean normally by inserting a cleaning tool such as a brush into these pipelines, the deposited urinary stone gradually grows to increase the deposition amount, and finally, There is a problem that there is a possibility that the connection pipeline and the drainage pipeline may be blocked.

When urinary stone adheres and deposits on the connecting pipeline connected to the rear side (downstream side) of such a drainage trap, the connection between this connecting pipeline and the drainage pipeline outside the urinal, etc. Since it is difficult to carry out the usual cleaning such as inserting and cleaning the cleaning tool as described above, the urinal once downstream of the external drainage pipe for every predetermined period to remove such urinals After removal from the channel, it is necessary to dissolve the urinary stone with a drug, pass through a rotary stone tool for attrition of the urinary stone, or remove it by high-pressure cleaning.
However, such a removal process is not only expensive, but also can not be used during the maintenance period, resulting in a large-scale processing operation, and there is also a problem that it can not be easily performed.

Then, in order to solve such a problem, for example, in the conventional urinal described in patent document 1, a cleaning tool can be inserted in the back bottom of the bowl part located above the outflow part of a drainage trap. Opening is formed. In addition, a short cylindrical socket is fixed to this opening, and an obturator integrally formed with a tray covering the outlet on the upstream side of the drainage trap is detachably attached to the socket. ing. Furthermore, a projection surface, which projects the opening cross section of the opening toward the drainage trap along the central axis, is formed at the top of the outlet of the drainage trap, and a cleaning tool is inserted from the opening by removing the closure. It is possible to clean the vicinity of the downstream outlet of the drainage trap.
Moreover, in the conventional urinal described in Patent Document 2, a through hole into which a high pressure hose for flush water supply can be inserted is formed on the rear bottom surface of the bowl portion located above the outflow portion of the drainage trap. . A projection surface, which projects the open cross section of this through hole toward the drainage trap along the central axis, is formed on the upper portion of the outlet of the drainage trap, and a high pressure hose for water supply is inserted into the through hole to wash it. By injecting high pressure wash water from the tip of the high pressure hose for water supply, it is possible to clean the drainage pipe connected to the outside of the rear side (downstream side) of the urinal without removing the urinal. It has become.

Since the distance H2 to the lower surface 50 of the tray 32 along the central axis A1 of the opening cross section S1 of the cleaning port 24 of the cleaning port 26 is set larger, the bottom surface and the inclined wall of the drainage port 8 are thereby set. A region R1 in the drainage port 8 between the side surface 22a of the drainage port 22 and the lower surface 50 of the tray 32 is formed with a space into which a sufficient amount of washing water including urine can flow. It has become. In addition, flush water that has cleaned urine in the bowl portion 4 flows along the bowl surface 4 a and passes through the gap G between the outer peripheral edge 34 of the tray 32 and the inner peripheral edge 36 of the drainage port 8 to drain it. When flowing into the inside, for example, even if washing water containing urine flows while being transmitted along the lower surface 50 (rear surface) of the tray 32, the lower surface 32 of the tray 50 and the closing tool 28 contact each other Since a gap is surely formed between the two, wash water containing urine can be effectively spread over the drain 8a.

Next, the operation of the urinal according to the embodiment of the present invention will be described with reference to FIGS.
In addition, the flow of the wash water is shown by the arrow about FIG.3 and FIG.4.
In the urinal 1, after the user urinates in the bowl portion 4, the water discharger 6 discharges the flush water supplied from the water supply pipe 6a to the bowl surface 4a. The flush water W0 spouted from the spout 6 flows from the upper side to the lower outlet portion 8 of the bowl surface 4a while washing.
The washing water W0 containing the urine that has reached the drainage port 8 is located near the upper part of the gap G between the rear end surface of the outer peripheral edge 34 of the tray 32 and the rear end surface of the inner peripheral edge 36 of the drainage port 8 And the washing water W1 relatively flowing forward and downward of the tray 32 along the upper surface (surface) of the tray 32 without flowing into the gap G, and the washing water W2 flowing into the gap G. Ru.

  Further, as shown in FIGS. 3 and 4, the washing water W1 relatively flowing forward and downward of the tray 32 along the upper surface of the tray 32 without flowing into the gap G is shown in FIG. Thus, while flowing toward the front end of the outer peripheral edge 34 of the tray 32, it flows toward the gap G between the outer peripheral edge 34 of the lateral tray 32 and the inner peripheral edge 36 of the drainage port 8 in the middle thereof After that, it flows into the drainage port 8 from the gap G, and thereafter, flows into the drainage port 8a to form a flow to be discharged. Alternatively, the washing water W1 relatively flowing forward and downward of the tray 32 along the upper surface of the tray 32 is, as shown in FIG. After flowing into the drainage port 8 from the gap G between the inner peripheral edge 36 and the front end face of the inner peripheral edge 36, a flow is formed which flows into the drainage port 8a along the bottom of the drainage port 8 and is drained.

On the other hand, the flush water W flowing into the gap G flows into the drainage port 8 along the rear end surface of the inner peripheral edge 36 of the drainage port 8, and then the side surface of the drainage port portion of the inclined wall 22 in the drainage port 8 The washing water W3 flowing toward the drainage port 8b along 22a is the main flow, but a portion of the washing water W2 flowing into the gap G is from the rear side of the lower surface (rear surface) 50 of the tray 32. It spreads along the lower surface 50 of the tray 32 relatively forward and downward along the lower surface 50 while being transmitted along the lower surface 50, and finally, flush water is drained in the drainage port 8. It merges with W1 and forms a flow which flows into the drainage port 8a and is discharged.
In addition, the cleaning port 24 and the closing tool 28 are completely separated by the sealing member 30 for the flush water W3 flowing toward the drain port 8b along the drain port side surface 22a of the inclined wall 22 in the drain port 8 Because it is sealed, it flows around the base member 40 of the closure 28 toward the drainage port 8 a without flowing into the cleaning port 24.
Thereafter, the flush water flowing from the drainage port 8 into the descending pipeline 12 of the drainage trap portion 10 pushes the urine accumulated in the drainage trap unit 10 to the downstream ascending pipeline 14, and from this ascending pipeline 14 to the drainage chamber 18. The flush water that has flowed into the inside flows downstream in the connection passage 20 and drains urine from the connection port 38 into the drainage pipe 16.

Below, the cleaning method in the connection passage part 20 and the drainage piping 16 more downstream than the drainage trap part 10 of the urinal 1 by one Embodiment of this invention is demonstrated.
First, the cleaner removes the tray 32 from the drainage port portion 8 as a preparation before cleaning the connection passage portion 20 and the drainage pipe 16 on the downstream side of the drainage trap portion 10 of the urinal 1.
Thereafter, in order to remove the closure 28 attached to the cleaning port 26, the projection 46a of the tool 46 is fitted from above into the recess 44b of the male screw member 44 of the closure 28 and the tool 46 is rotated about its central axis A2. By rotating the male screw member 44 about its central axis A2 by turning in a predetermined direction, a direction in which the male screw 44a of the male screw member 44 and the female screw hole 42a of the lower locking member 42 are unscrewed from each other To loosen the attachment of the closure 28 to the cleaning port 26 of the inclined wall 22.
Thereby, the inclined wall 22 of the cleaning port 26 is between the skirt portion 40c and the seal member 30 of the base member 40 on the side of the drainage port 8 and the projecting portion 42b of the lower locking member 42 on the side of the drainage chamber 18 The locking by the lower locking member 42 of the closure 28 from the drainage chamber 18 side to the inclined wall 22 of the cleaning port 26 is released.

Next, regarding the obturator 28, the tip of the protrusion 42b of the lower locking member 42 is from the state where the tip of the protrusion 42b of the lower locking member 42 shown in FIG. 4 is directed forward and downward. After rotating the closing tool 28 around the central axis A2 so as to be directed rearward and upward, the closing tool 28 is pulled out toward the drainage port 8 side with respect to the cleaning port 26 for the entire closing tool 28. Is removed to the cleaning port 26.
Then, a cleaning tool (not shown) such as a brush or a nozzle of high pressure cleaning water is inserted into the opened cleaning port 24. Here, when using a cleaning tool (not shown) such as a nozzle of high pressure cleaning water, high pressure cleaning water is jetted from the tip of the nozzle (not shown).
Then, the urinary stone attached to the connection passage 20 and the drainage pipe 16 is removed by high-pressure washing water, and the urine is pushed downstream and cleaned.

Also, instead of using a high pressure cleaning water nozzle (not shown), a drug may be introduced through the opened cleaning port 24 to dissolve the uristone. In addition, the urinary stone may be abraded by passing it through a grinding tool (not shown) for abrading the urinary stone.
By simply removing the blocking tool 28 from the cleaning port 24 and inserting a high-pressure cleaning water nozzle (not shown) or injecting a medicine in this manner, the connection passage 20 and the drainage pipe 16 can be simply and reliably made. Since the cleaning can be performed, the connection passage portion 20 downstream of the drainage trap portion 10 can be cleaned without removing the urinal 1 from the drainage pipe 16, and the cleaning work can be completed in a short time.
Therefore, the user can use the urinal 1 to clean the urinal 1 because cleaning can be performed in a shorter time than before even in a public restroom space where there are many users such as rest areas on expressways It is possible to keep the time that can not be done short.

Next, when cleaning of the urinal 1 is completed, the cleaning tool (not shown) is pulled out from the cleaning port 24 to the drainage port 8 side, and then the closing tool 28 is attached to the cleaning port 26. At this time, the protruding portion 42 b of the lower locking member 42 of the closing tool 28 is inserted into the cleaning port 24 in a state where the tip end of the protruding portion 42 b of the lower locking member 42 is directed rearward and upward. The tip end of the protrusion 42b is disposed in the drainage chamber 18 with the tip directed rearward and upward.
Thereafter, as shown in FIG. 4, the entire closure 28 is rotated about the central axis A2 so that the tip of the projection 42b of the lower locking member 42 is directed forward and downward. The protrusion 46a is inserted into the recess 44b of the male screw member 44 of the closure 28 from above, and the male screw member 44 is rotated about the central axis A2 by rotating the tool 46 in a predetermined direction about the central axis A2. The screwing of the male screw 44a of the member 44 and the female screw hole 42a of the lower locking member 42 is rotated in the forward direction to strengthen the attachment of the closure 28 to the cleaning port 26 of the inclined wall 22. Then, the upper surface of the projecting portion 42b abuts on the drainage chamber side surface 22b of the inclined wall 22 from the drainage chamber 18 side, so that the inclined wall 22 of the cleaning port 26 is the skirt portion 40c of the base member 40 on the drainage port 8 side. It is held between the seal member 30 and the projection 42 b of the lower locking member 42 on the side of the drainage chamber 18.
Finally, the tray 32 is attached to the inside of the drainage port 8 so that the urinal 1 can be used.

According to the urinal 1 according to the embodiment of the present invention described above, the tray 32 attached to the drainage port 8 formed at the bottom of the bowl section 4 comprises the drainage port 8a, the cleaning port 26 and the cleaning By being attached so as to cover in a spaced state with respect to all of the obturator 28 attached to the mouth portion 26, flush water which has cleaned urination in the bowl portion 4 flows along the bowl surface 4a, Even if the washing water W4 containing urine flows along the lower surface (rear surface) 50 of the tray 32 as shown in FIG. Since the gap between the lower surface 50 of the tray 32 and the closing tool 28 is reliably formed without contact with each other, the wash water containing urine can be easily spread over the drainage port 8a. . As a result, drainage efficiency can be improved, and it is possible to make it difficult for wash water containing urine to be transmitted from the lower surface 50 of the tray 32 to the closure 28.
Moreover, since it can also suppress that urine adheres as urinary stone by staying in the closing tool 28 and the cleaning port 26, when removing the closing tool 28 from the cleaning port 26 along with cleaning of the urinal 1 In addition, it is possible to prevent the problem of attachment / detachment caused by the attachment of the urination to the closing tool 28 and the cleaning port 26.

  Further, according to the urinal 1 according to the present embodiment, the distance H1 from the drainage port 8a to the lower surface 50 of the tray 32 along the central axis A4 is the distance from the head end surface 44d of the male screw member 44 of the closure 28. The washing water used to wash urine in the bowl 4 by setting the distance H2 to the lower surface 50 of the tray 32 along the central axis A1 of the opening cross section S1 of the cleaning opening 24 of the cleaning opening 26 Flows along the bowl surface 4 a and passes through the gap G between the outer peripheral edge 34 of the tray 32 and the inner peripheral edge 36 of the drainage port 8 and flows into the drainage port 8, for example, containing urine. Even if the washing water flows along the lower surface 50 (rear surface) of the tray 32, the lower surface 50 of the tray 32 and the closing tool 28 do not contact each other, and a gap is reliably formed between them. Drain water from the urine effectively Can be easily spreads to a, it is possible to further improve the drainage efficiency.

Furthermore, according to the urinal 1 according to the present embodiment, when the gap is formed between the lower surface 50 of the tray 32 and the closing tool 28, for example, when cleaning the surface of the tray 32, etc. If a force is applied to a part of the surface of the tray 32 and the tray 32 may be tilted, the tray 32 may have a plurality of projections 52, 54 projecting downward from the lower surface 50 thereof. 56 is provided, the tilting of the tray 32 from the state of being attached to the drainage port 8 makes it possible for the pair of side protrusions 54 and 56 of the plurality of protrusions 52, 54 and 56 to be inclined. One of them can be in contact with the upper surface of the skirt portion 40 c of the base member 40 of the closure 28 to limit the inclination of the tray 32.
Therefore, by applying a force to a part of the surface of the tray 32, it is possible to prevent the tray 32 from rotating beyond the limit of inclination and coming off from the drainage port 8.

Moreover, according to the urinal 1 according to the present embodiment, the projection surface S2 projected the opening cross section S1 of the cleaning port 24 of the cleaning port 26 toward the connection passage 20 of the drainage chamber 18 along the central axis A1 is By forming the bottom surface 20a of the connection passage portion 20 of the drainage chamber 18, when cleaning the urinal 1, without removing the entire urinal 1 relative to the drainage pipe 16 outside the urinal 1, an eye The cleaning tool (not shown) can be inserted into the drainage chamber 18 through the cleaning port 24 from the drainage port 8 side only by removing the blocking tool 28 from the cleaning port 26 after removing the plate 32. Thus, the vicinity of the bottom surface 20 a of the connection passage 20 of the drainage chamber 18 formed on the rear side (downstream side) of the drainage trap 10 can be cleaned easily and reliably.
Therefore, it can be suppressed that urinary stone adheres and deposits near the bottom surface 20a of the connection passage portion 20 of the drainage chamber 18 on the rear side (downstream side) of the drainage trap portion 10, and the bowl surface 4a is cleaned. It is possible to prevent clogging of drainage of the connection passage portion 20 discharged from the drainage trap portion 10.

Furthermore, according to the urinal 1 according to the present embodiment, the projection surface S2 projected from the opening cross section S1 of the cleaning port 24 of the cleaning port 26 toward the connection passage 20 along the central axis A1 is the drainage surface 18 By being formed at the rear end (downstream end) 20b of the connection passage portion 20, it is connected to the inside of the connection passage portion 20 where urstones are easily attached and accumulated, particularly to the drainage pipe 16 outside the urinal 1. In the rear end portion (downstream side end portion) 20b of the connection passage portion 20 to be removed, the urinary stones can be formed in the connection passage portion 20 (in particular, by simply removing the closing tool 28 from the cleaning port 26 after removing the eyeglass 32). Whether or not the downstream end 20b) of the connection passage 20 is attached can be confirmed more easily by simple visual inspection.
Also, when cleaning the urinal 1, without removing the entire urinal 1 with respect to the drainage pipe 16 outside the urinal 1, after removing the eyelet 32, the obturator 28 is removed from the cleaning port 26 The cleaning tool (not shown) can be inserted into the drainage chamber 18 from the drainage port 8 side through the cleaning port 24 alone. As a result, the vicinity of the downstream end 20b of the connection passage 20 of the drainage chamber 18 to which the drainage pipe 16 outside the urinal 1 is connected can be cleaned easily and reliably. Therefore, it is possible to suppress the deposition and accumulation of urine and stone near the downstream end 20b of the connection passage 20 of the drainage chamber 18, and the connection discharged from the drainage trap 10 by cleaning the bowl surface 4a. Clogged drainage of the passage 20 can be prevented.

  In addition, about the urinal 1 by one Embodiment of this invention mentioned above, although the form which wash | cleans the bowl surface 4a using the wash water discharged from the water discharging apparatus 6 was demonstrated, without providing the water discharging apparatus 6, It is applicable also about the form of the anhydrous urinal which does not use the wash water W for wash | cleaning the bowl surface 4a.
