Description

  The present invention relates to a urinal drain trap and a non-flush urinal.

  Patent Document 1 discloses a conventional urinal drain trap. This urinal drain trap is disposed at the lower end of the toilet bowl of the non-washing urinal, and forms a flow path having a water seal inside. This urinal drain trap has a holding member provided above the upper wall. This holding member holds a medicine containing citric acid or the like.

  This drug can be dissolved and flow into the water seal of the urinal drain trap. When the dissolved medicine flows into the water seal portion, the liquidity in the water seal portion can be maintained acidic. For this reason, it can suppress that the calcium ion which melt | dissolved in urine by the liquid property in a water seal part becoming alkaline changes into a hardly soluble calcium compound (urine stone).

The first scraper portion 33 is formed in a flat plate shape and extends outward from the lower end portion of the main body portion 32. The first scraper portion 33 is disposed below the intermediate bottom portion 22. The lower end of the first scraper portion 33 extends along the inner wall surface X that is the upper surface of the bottom wall portion 19 of the urinal drain trap 10. Moreover, the 1st scraper part 33 forms the outer side edge part continuously from a lower end part, and this outer side edge part is extended along the inner wall face X of the side wall part 18 of the drainage trap 10 for urinals. That is, the lower end portion and the outer end portion of the first scraper portion 33 extend along the inner wall surface X that forms the flow path. The first scraper portion 33 is provided with a plurality of circular through holes 33A.

  Moreover, the 1st scraper part 33 forms continuously the convex part 33B which protruded so that it might fit in the 1st downward flow path 13 in the outer side upper end part. The convex portion 33 </ b> B extends along the inner wall surface X that forms the side surface of the first descending flow path 13 at the outer end portion and the inner end portion. That is, as for this convex part 33B, an outer side end is along the inner peripheral surface of the side wall part 18 of the drainage trap 10 for urinals, and an inner side end part is along the outer peripheral surface of the folding | turning part 23.

  The second scraper portion 34 is formed to extend in the vertical direction on the side surface portion of the main body portion 32. The second scraper portion 34 is fitted into the ascending channel 14, and the outer end and the inner end are formed along the inner wall surface X that forms the side surface of the ascending channel 14. That is, the second scraper portion 34 has an outer end portion along the inner peripheral surface of the partition wall portion 21 and an inner end portion along the outer peripheral surface of the outflow pipe portion 24.

  The third scraper portion 35 includes a horizontal portion 35A extending inward from the inner peripheral surface of the main body portion 32 above the upper end of the outflow pipe portion 24, and a hanging portion extending vertically downward from the tip portion of the horizontal portion 35A. 35B.

  In the non-washing urinal 1 having such a configuration, urine stays in the water seal portion 11 when the user uses, and the seal layer S is formed in the water seal portion 11 outside the partition wall portion 21. (In addition, when the use of the urinal drain trap 10 is started, tap water is retained instead of urine.) When the user urinates toward the toilet bowl 2, urine flows down along the surface of the toilet bowl 2 and flows into the upper surface of the upper wall 17 of the urinal drain trap 10. The urine that has flowed into the upper surface of the upper wall portion 17 flows into the urinal drain trap 10 from the inlet 12. Then, urine passes through the sealing layer S and flows between the partition wall 21 and the folded portion 23 from above. The urine flows over the upper end portion of the turn-up portion 23 and flows outside the turn-up portion 23 while generating convection that changes from descending to rising in a region surrounded by the partition wall portion 21, the intermediate bottom portion 22, and the turn-up portion 23. The urine that has passed over the upper end of the folded portion 23 flows downward through the first descending flow path 13. As described above, the first descending flow path 13 communicates with the downstream side of the inflow port 11.

  Urine that flows downward through the first descending flow path 13 and between the bottom wall portion 19 and the intermediate bottom portion 22 flows into the ascending flow path 14 and flows upward. As described above, the ascending flow path 14 communicates with the downstream side of the first descending flow path 13. The urine that has flowed upward in the ascending flow path 14 gets over the upper end of the outflow pipe portion 24, flows into the second descending flow path 15, and flows downward. As described above, the second descending flow path 15 communicates with the downstream side of the ascending flow path 14. Urine that has flowed downward through the second descending flow path 15 flows out from the outlet 16 into the storage container 4. As described above, the outlet 16 communicates with the downstream side of the second descending flow path 15. The urine that has flowed into the storage container 4 is discharged to the drain pipe 8 drawn out to the wall surface W through the connecting pipe portion 4A of the storage container 4.

  Further, the urinal drain trap 10 periodically rotates the clog prevention mechanism 30 within the urinal drain trap 10 using the knob 31B of the rotary shaft 31 of the clog prevention mechanism 30. As a result, the first to third scraper portions 33, 34, and 35 move along the inner wall surface X that forms the side surface of each flow path. It can be separated from the inner wall surface X and / or stirred in the water seal 11. For this reason, urine stones or the like can be easily flowed to the downstream side of the flow path by the urine flowing in the flow path of the urinal drain trap 10. Therefore, it is possible to prevent urine stones from adhering to and / or depositing on the inner wall surface X that forms the flow path of the urinal drain trap 10.

  Therefore, the non-washing urinal 1 provided with the urinal drain trap 10 of Example 1 can prevent clogging of the flow path in the urinal drain trap 10.

  Moreover, since the through-hole 33A is penetrated by the 1st scraper part 33, when the clogging prevention mechanism 30 is rotated, urine stone etc. will pass through the through-hole 33A. Thereby, urine stones and the like can be made fine. For this reason, since urine stones and the like can be satisfactorily stirred in the water seal portion 11, the urine stones and the like are easily flowed to the downstream side of the flow channel by the urine flowing in the flow channel of the urinal drain trap 10. be able to.

<Example 2>
As shown in FIG. 6, the urinal drain trap 50 of the second embodiment is different from the first embodiment in the configuration of the rotating shaft portion 61 of the clogging prevention mechanism 60 and the form of the upper wall portion 57 of the urinal drain trap 50. . Other configurations are the same as those of the first embodiment, and the same configurations are denoted by the same reference numerals and detailed description thereof is omitted.

  The clogging prevention mechanism 60 forms a columnar rotating shaft portion 61 having an outer diameter that is the same as the outer diameter of the main body portion 62 continuously from the upper portion of the main body portion 62. The upper end surface of the rotary shaft 61 is close to the lower surface of the upper wall portion 57 of the urinal drain trap 50. The rotating shaft 61 has a disk-shaped magnet 61A. The rotating shaft portion 61 and the main body portion 62 are rotatably arranged in the partition wall portion 21 of the urinal drain trap 50.

  The inside of the upper wall portion 57 where the partition wall portion 21 hangs down is closed. For this reason, odor does not leak from the inside of the partition wall 21 to the outside of the urinal drain trap 50. The upper wall portion 57 has a concave portion 57A in which the upper surface of the central portion is recessed in a circular shape. The recess 57A can place the knob member 70 of the clogging prevention mechanism 60. The knob member 70 includes a disk-shaped base portion 70A and a prismatic knob portion 70B formed to protrude upward from the upper surface of the base portion 70A. The base portion 70A has an outer diameter that is slightly smaller than the outer diameter of the recess 57A, and can be placed in the recess 57A. The knob member 70 is formed of a magnet, and when placed in the recess 57A formed in the upper wall portion 57, the magnet 61A built in the rotary shaft portion 61 can be drawn.

  In the urinal drain trap 50 configured as described above, the knob member 70 is not normally placed in the recess 57A formed in the upper wall portion 57, and the clogging prevention mechanism 60 is rotated in the urinal drain trap 50. At this time, the knob member 70 is placed in the concave portion 57 </ b> A formed in the upper wall portion 57. When the knob member 70 is placed in the recess 57 </ b> A formed in the upper wall portion 57, the knob member 70 attracts the magnet 61 </ b> A built in the rotation shaft portion 61 of the clogging prevention mechanism 60, and thus the knob portion 70 </ b> B of the knob member 70. Can be used to rotate the clogging prevention mechanism 60. When the clogging prevention mechanism 60 is rotated in the urinal drain trap 50 in this manner, the first to third scraper portions 33, 34, and 35 move along the inner wall surface X that forms the side surface of each flow path. Therefore, urine stones that adhere to and / or deposit on each inner wall surface X can be separated from each inner wall surface and / or stirred in the water seal 11. For this reason, urine stones or the like can be easily flowed to the downstream side of the flow path by the urine flowing in the flow path of the urinal drain trap 50. Therefore, it is possible to prevent urine stones from adhering to and / or depositing on the inner wall surface X that forms the flow path of the urinal drain trap 50.

  Therefore, the non-washing type urinal 1 provided with the urinal drain trap 50 of Example 2 can also prevent clogging of the flow path in the urinal drain trap 50.
