  In this kind of urinal drain trap, it is inevitable that sediment in urine will settle at the bottom of the storage space. When this precipitated urinary sediment remains in the storage space without reaching the discharge port when urine is discharged, and the accumulated amount of the urinary sediment exceeds the dip in the sealed water part, it is sealed. There is a concern that the upstream end of the water portion may be blocked by sediment in urine and cannot be drained.

  The present invention has been completed based on the above-described circumstances, and an object thereof is to prevent the drainage from being hindered due to accumulation of sediment in urine.

  As means for achieving the above object, the invention of claim 1 is arranged at the lower end of the bowl surface of the urinal and has a main body having a storage space for storing urine, and urine in the storage space. And a lower end dip in communication with the bottom of the storage space and an upper end wear in communication with the discharge port, and the urine in the storage space A drainage trap for urinals having a sealing part that becomes a urine rising channel when discharged, an operation part, a discharge function part arranged in the sealing part, and a movement of the operation part An operation force transmission unit that transmits to the discharge function unit, and by operating the operation unit, the discharge function unit pulls up the urine sediment located below the dip to the discharge port. Specially where there is a discharge member Having.

  A seventh aspect of the present invention is the cartridge according to any one of the first to sixth aspects, wherein the cartridge is detachably attached to a recess opened upward at a lower end portion of the bowl surface of the urinal. It has the characteristics where it is done.

<Invention of Claim 1>
When the operation part is operated to displace the discharge function part, the urine sediment precipitated below the dip is pulled up by the discharge function part and discharged from the discharge port to the outside of the main body part. Thereby, it is possible to prevent the drainage from being hindered due to accumulation of sediment in urine.

<Invention of Claim 2>
When discharging the urine sediment, the discharge member functions as a screw feeder by rotating the spiral discharge function portion, and the urine precipitate is pulled up to the discharge port. In addition, since the discharge function part is a spiral plate, the flow path of urine in the sealed water part is narrowed and the flow rate of urine is increased, so that sediment in the urine is difficult to settle in the sealed water part, Goods can be discharged reliably.

<Invention of Claim 3>
Since the inner wall surface of the sealed water part and the axis of the operating force transmission part are inclined with respect to the vertical direction, the discharged urine sediment was blocked by the discharge function part on the inner wall surface of the sealed water part. It will move in the state, and the discharge efficiency is high.

<Invention of Claim 4>
Focusing on the point that the operation unit is required only when discharging sediment in urine, the operation unit was made detachable from the operation force transmission unit. Thereby, since one operation part can be shared with respect to the several urinal drain traps, the number of parts can be reduced.

<Invention of Claim 5>
The urine sediment that settles in the storage space falls on the guiding slope, but the guiding slope is inclined downward toward the dip, so the urine sediment is tilted by the slope of the guiding slope. Gather near the dip. This can reduce the amount of urine sediment that remains without being discharged on the bottom surface of the storage space.

<Invention of Claim 6>
When discharging the sediment in urine, the upper part of the discharge member may be exposed by displacing the eye plate. Since the upper end of the discharge member is always covered with the eye plate, the upper end of the discharge member is damaged by foreign matter interference, soiled with urine, or attached to sediment in the urine. It is possible to avoid problems such as disturbing the displacement operation of the discharge member.

<Invention of Claim 7>
Maintenance can be easily performed because the entire cartridge can be replaced when clogging or the like occurs due to a decrease in sealing liquid or accumulation of gel-like urine stone.

The cross-sectional shape orthogonal to the penetrating direction of the ascending channel 16 is a perfect circle. A lower end of the sealed water portion 15, that is, a dip 17 that is an upstream end of the ascending flow path 16 communicates with the bottom portion of the storage space 12. The ascending flow path 16 of the sealed water portion 15 faces a direction parallel to the guide slope 13, that is, a direction inclined with respect to the vertical direction.

  The discharge port 18 is formed at the upper end portion of the main body portion 11 so as to communicate with the upper end of the sealing portion 15, that is, the wear 19 that is the downstream end of the ascending flow path 16 in the vicinity thereof. That is, the lower end in the opening area of the discharge port 18 is the wear 19. Further, a discharge path 20 that is continuous with the discharge port 18 is formed in the main body 11. The discharge path 20 has a form extending downward in the vertical direction from the discharge port 18, and the inside of the discharge path 20 is a fall space 21 whose entire circumference is surrounded by a peripheral wall portion over the entire length. The upper end (upstream end) of the discharge path 20 (falling space 21) faces the discharge port 18, and the opening at the lower end (downstream end) of the discharging path 20 (falling space 21) faces the upstream end of the connecting pipe 6.

  The lid 22 is assembled to the main body 11 so as to close the opening on the upper surface thereof. In the state in which the urinal drain trap A is housed in the storage container 3, the lid 22 is in a state of closing the opening on the upper surface of the cylindrical portion 4 of the storage container 3, and the outer peripheral edge of the lid 22 is relative to the inner periphery of the upper end portion of the cylindrical portion 4. Are fitted in a liquid-tight manner.

  A through hole 23 is formed in the lid 22, and a receiving member 24 is assembled in the through hole 23. The receiving member 24 has a container shape with an open upper surface, and the upper end portion of the receiving member 24 is fitted in the through hole 23. The opening on the upper surface of the receiving member 24 serves as an inlet 25 for allowing urine to flow into the storage space 12. Further, a communication hole 26 is formed in the peripheral wall of the receiving member 24 in a form in which a region above the bottom wall portion is partially opened.

  The sealing portion 15 is provided with a discharge member 30. The discharge member 30 includes a shaft 31 concentric with the ascending flow path 16 (an operation force transmitting portion which is a constituent element of the present invention), and a flange formed integrally with a concentric disk at a position close to the upper end of the shaft 31. Part 32, upper end of shaft part 31, that is, operation part 33 provided at a position above flange part 32 in shaft part 31, and the outer periphery of shaft part 31 is formed in a spiral shape and is integral with shaft part 31. It has a plate-like screw part 34 (a discharge function part which is a constituent element of the present invention) formed so as to rotate.

  The operation portion 33 includes a prismatic connecting portion 35 formed above the flange portion 32 in the shaft portion 31, and a handle 36 that can be fitted to the connecting portion 35 via the adapter 37 so as to be able to make a major rotation. And is configured. Further, a sealing member 38 can be fitted into the connecting portion 35 from above. The seal member 38 and the handle 36 can be attached to and detached from the connecting portion 35, and either one of the seal member 38 and the handle 36 is selectively fitted into the connecting portion 35.

  The discharge member 30 is rotatably supported by the bearing member 39 and the bearing hole 40. The bearing member 39 is attached to the lid 22 so as to penetrate coaxially with the ascending flow path 16. The bearing hole 40 is formed by notching the bottom surface of the storage space 12 coaxially with the ascending flow path 16. The bearing member 39 is fitted so that the outer peripheral surface of the flange portion 32 can be slidably contacted, and is in contact with the outer peripheral edge of the upper surface of the flange portion 32 so as to be slidably contacted. The lower end portion of the shaft portion 31 is rotatably fitted in the bearing hole 40, and the lower end surface of the shaft portion 31 is in contact with the bottom surface (lower end surface) of the bearing hole 40.

  The discharge member 30 rotatably supported by the bearing member 39 and the bearing hole 40 is in a state in which relative displacement in the axial direction is restricted with respect to the trap body 10. Further, the shaft portion 31 penetrates the sealed portion 15, and the screw portion 34 is located in the ascending flow path 16 of the sealed portion 15. In addition, a minimum clearance is secured between the outer peripheral edge of the screw portion 34 and the inner peripheral surface of the ascending flow path 16 in order to ensure smooth rotation of the discharge member 30. The lower end of the screw part 34 is disposed below the dip 17 so as to be located in the bottom part of the storage space 12. Further, the upper end of the screw portion 34 is disposed at a position slightly above the wear 19, that is, at a height corresponding to at least a part of the opening area of the discharge port 18.

  A detachable eye plate 41 is provided above the lid 22. The eye plate 41 includes a cover portion 42 having a disk shape substantially the same size as the lid 22, and a plurality of leg portions 43 extending downward from a position close to the outer peripheral edge of the lower surface of the cover portion 42. Usually, the eye plate 41 is attached so that the leg portion 43 is placed on the upper surface of the lid 22. When attaching the eye plate 41, the seal member 38 is attached to the connecting portion 35. In a state in which the eye plate 41 is attached, as shown in FIG. 1, the eye plate 41 protrudes upward from the flow path of urine from the sealed portion 15 to the discharge port 18 in the discharge member 30 (connection). Part 35 and seal member 38), bearing member 39 and inflow port 25. In addition, a gap for allowing urine to flow is provided between the lower surface of the outer peripheral edge of the eye plate 41 and the upper surface of the lid 22 over the entire circumference.

  When the eye plate 41 is removed, as shown in FIG. 2, the upper end portion (the connecting portion 35 and the handle 36) of the discharge member 30 is exposed. Therefore, by removing the eye plate 41, the seal member 38 is removed from the connecting portion 35, the operation of replacing the handle 36 with the connecting portion 35, the operation of rotating the handle 36, the handle 36 being removed from the connecting portion 35, The operation of replacing the seal member 38 with the connecting portion 35 can be performed.

  Usually, a predetermined amount of urine is stored in the storage space 12 and the sealed water portion 15 (the ascending flow path 16). At this time, the liquid level of the urine in the ascending flow path 16 is the same height as the wear 19, and the urine is filled in the ascending flow path 16, whereby a strange odor from the drain pipe is released to the urinal 1 side. The sealed water state is prevented. Moreover, in the storage space 12, the liquid level of urine is covered with a water-insoluble sealing liquid having a specific gravity smaller than that of urine. The sealing liquid prevents the urine stored in the storage space 12 from directly touching the atmosphere, so that a strange odor emitted from the urine is not diffused into the atmosphere. The liquid level of the sealing liquid in the storage space 12 is slightly higher than the liquid level of urine in the ascending flow path 16.

  When urination is performed toward the urinal 1, the urine flows through the bowl surface 2 and passes through the gap between the eye plate 41 and the lid 22, or flows through the upper surface of the eye plate 41, and the eye plate 41 and the lid 22. After passing through a path passing through the gap, the air flows along the upper surface of the lid 22 and flows into the storage space 12 from the inflow port 25. The urine that has flowed into the storage space 12 passes through the sealing liquid and once enters the receiving member 24, and then passes through the communication hole 26 and is mixed with the urine in the storage space 12. The urine in the storage space 12 flows in the ascending flow path 16 of the sealed water portion 15 through the outflow port 17, falls from the discharge port 18 through the discharge path 20 to the upstream end portion of the connecting pipe 6, and the water distribution pipe. Is discharged. In addition, although the screw part 34 of the discharge member 30 exists in the ascending flow path 16, since the screw part 34 is a form in which a single plate is formed in a spiral shape, the internal space of the ascending flow path 16 is defined by the screw part 34. The urine can ascend in the ascending channel 16 without hindrance.

  In addition, a part of the sealing liquid is drawn into the receiving member 24 due to the inflow of urine. However, since the drawn sealing liquid is bounced back to the bottom wall portion of the receiving member 24, a storage space is formed from the receiving member 24. Even if it flows out into the interior 12, there is no risk of reaching the bottom of the storage space 12. Moreover, since the specific gravity of the sealing liquid is smaller than that of urine, when the momentum of inflow of urine is weakened, the sealing liquid rises due to buoyancy and merges with the sealing liquid covering the urine liquid surface. Therefore, there is no possibility that a large amount of the sealing liquid is discharged from the discharge port 18, and the decrease in the sealing liquid can be suppressed even if the service period is long.

  While the inflow of urine is not performed, urine sediment (not shown) settles and falls to the bottom surface of the guiding slope 13 and the storage space 12. Here, since the guide slope 13 is inclined so as to become a downward slope toward the dip 17 (outlet 14) with respect to the horizontal plane, the urinary sediment falling on the guide slope 13 It rolls down according to the inclination and reaches the bottom of the storage space 12, that is, a position near the dip 17. In this way, most of the urine precipitate is collected in the vicinity of the dip 17.

  Most of the urine sediment collected at the bottom of the storage space 12 is wound up by the urine flow when the urine flows from the storage space 12 into the ascending flow path 16, and rises up the ascending flow path 16. Then, although it is discharged from the discharge port 18, it is inevitable that a part of the urine precipitate remains at the bottom of the storage space 12 without being discharged. The remaining urinary sediment is accumulated to form a purine form. However, when the remaining urinary sediment accumulates until it becomes higher than the dip 17, the urine from the storage space 12 to the ascending flow path 16 is accumulated. There is concern that the outflow will be hindered.

  In order to avoid this, it is necessary to forcibly discharge the remaining urine sediment. This operation is performed as follows. First, the eye plate 41 is removed, and then the seal member 38 is removed from the connecting portion 35. Thereafter, the handle 36 is attached to the connecting portion 35, and the handle 36 is rotated. Then, the rotational force of the handle 36 is transmitted to the screw portion 34 via the shaft portion 31, and the screw portion 34 rotates in the ascending flow path 16 and the bottom space of the storage space 12. At this time, since the lower end portion of the screw part 34 is immersed in the remaining urinary sediment, the urinary sediment is transferred to the upper surface of the screw part 34 as the screw part 34 rotates. It is raised at.

  Further, since the rotating shaft (shaft portion 31) of the screw part 34 and the inner wall surface of the ascending flow path 16 are inclined with respect to the vertical direction, the outer peripheral edge of the screw part 34 is close to the inner wall surface of the ascending flow path 16. The upper half of the inner wall surface of the ascending flow channel 16 is opened upward and the upper half of the screw portion 34 is opened upward between the substantially semicircular region below the shaft portion 31. A storage space is formed, and the urine sediment is stored in the storage space. That is, the screw part 34 supports the urine sediment on the inner wall surface of the ascending flow path 16 so as to dam up the sediment. As a result, the urine sediment remaining and accumulated at the bottom of the storage space 12 is reliably lifted, discharged from the discharge port 18, and falls into the connecting pipe 6 through the discharge path 20. Moreover, since the screw part 34 as the discharge function part is a spiral plate, the flow path of urine in the sealed water part 15 (ascending flow path 16) is narrowed and the flow rate of urine is increased. Inside, urine precipitates are difficult to settle. Therefore, the urine precipitate can be discharged reliably.

  The urinal drain trap A of the first embodiment includes an operation unit 33, a screw unit 34 as a discharge function unit disposed in the sealing unit 15, and an operation force that transmits the movement of the operation unit 33 to the screw unit 34. It has the discharge member 30 provided with the axial part 31 as a transmission part. When the operating portion 33 is operated and the screw portion 34 is rotated, the urine sediment precipitated below the dip 17 is pulled up by the screw portion 34 and discharged out of the main body portion 11 from the discharge port 18. It has come to be. Therefore, according to the urinal drain trap A of the first embodiment, it is possible to prevent the drainage from being hindered due to accumulation of sediment in urine.

  Further, in the first embodiment, focusing on the fact that the operation unit 33 is required only when the urine sediment is discharged, the operation unit 33 can be attached to and detached from the shaft unit 31. A handle 36 was provided. Thereby, since one handle 36 (operation part 33) can be shared with respect to a plurality of urinal drain traps A, the number of parts can be reduced.

  The urine sediment that settled in the storage space 12 falls on the guide slope 13. Since the guide slope 13 is inclined so as to have a downward slope toward the dip 17, urine precipitates gather near the dip 17 due to the slope of the guide slope 13. Thereby, the amount of urine sediment that remains without being discharged on the bottom surface of the storage space 12 can be reduced.

  Moreover, between the state which covers the upper end part which protruded upwards rather than the flow path of the urine from the sealing part 15 to the discharge port 18 among the discharge members 30, and the state which exposes the upper end part of the discharge member 30 An eye plate 41 that can be displaced is provided. Since the upper end portion of the discharge member 30 can always be covered with the eye plate 41, the upper end portion of the discharge member 30 is damaged by foreign matter interference, stained with urine, urine sediment, etc. It is possible to avoid a problem that the displacement operation of the discharge member 30 is hindered by the adhesion.

  Further, the urinal drain trap A of the first embodiment is formed in a cartridge form that is detachably attached to a recess 7 that opens upward at the lower end of the bowl surface 2 of the urinal 1. According to this configuration, the cartridge can be replaced when the sealing liquid is reduced or clogging due to the accumulation of gel-like urinary stones, so that maintenance is easy.

<Embodiment 2>
Next, a second embodiment of the present invention will be described with reference to FIGS. In the urinal drain trap B of the second embodiment, the discharge path 50 is configured differently from the first embodiment. Since other configurations are the same as those of the first embodiment, the same configurations are denoted by the same reference numerals, and descriptions of structures, operations, and effects are omitted.

  In the said Embodiment 1, although the discharge path 20 was a form which has the fall space 21 enclosed by the surrounding wall part for the perimeter, the discharge path 50 of this Embodiment 2 is the main-body part 11 (trap main body 10). The outer surface is recessed into a groove extending in the vertical direction. The upper end of the discharge path 50 communicates with the discharge port 18 and faces the wear 19. Further, the lower end of the discharge path 50 faces the connecting pipe 6.

<Embodiment 3>
Next, a third embodiment of the present invention will be described with reference to FIG. In the urinal drain trap C of the third embodiment, the discharge member 60 is configured differently from the first and second embodiments. Since other configurations are the same as those of the first embodiment, the same configurations are denoted by the same reference numerals, and descriptions of structures, operations, and effects are omitted.

  In the discharge member 60 of the third embodiment, the plate portion 62 (the discharge function portion which is a component of the present invention) is integrally displaced at the lower end portion of the shaft portion 61 (the operation force transmission portion which is a component of the present invention). This is a configuration in which the knob portion 63 (the operation portion which is a constituent element of the present invention) is attached to the upper end portion of the shaft portion 61 so as to be integrally displaceable. The shaft portion 61 is penetrated through a bearing member 64 provided on the lid 22 so as to be capable of relative displacement in the axial direction. By this bearing member 64, the discharge member 60 causes the plate portion 62 to be substantially in close contact with the bottom surface of the storage space 12. Move in the vertical direction (direction along the axis of the shaft portion 61) between the lowermost standby position (see FIG. 5) and the discharge position (not shown) where the plate portion 62 is higher than the wear 19 It has come to be able to do.

  The plate portion 62 has a circular shape concentric with the ascending flow path 16, and the outer peripheral edge of the plate portion 62 has a minimum clearance necessary for allowing the discharge member 60 to move smoothly with respect to the inner wall surface of the ascending flow path 16. Facing each other. Further, the upper end portion of the shaft portion 61 penetrates the bearing member 64 and protrudes upward, and a knob portion 63 is fixed to the protruding portion. Therefore, the knob 63 is exposed above the lid 22 regardless of the position of the discharge member 60 between the standby position and the discharge position.

  Normally, the discharge member 60 is held at the standby position, and the plate portion 62 is in close contact with the bottom surface of the storage space 12, that is, is immersed in the urine sediment accumulated at the bottom of the storage space 12. It has become. At this time, since the plate portion 62 is located at the lower end in the opening region of the outlet 17 that allows the storage space 12 and the ascending flow path 16 to communicate with each other, the flow of urine from the storing space 12 to the ascending flow path 16 Will not be disturbed.

  When the urine sediment accumulated at the bottom of the storage space 12 is discharged, the knob 63 is picked to lift the discharge member 60. Then, the urine sediment is pulled up while being placed on the upper surface of the plate portion 62. When the discharge member 60 rises to the discharge position, the urine sediment placed on the plate portion 62 is pushed to the side by being pressed against the lower surface of the bearing member 64 and discharged from the discharge port 18.
