Description

Drain trap for urinals {URINAL DRAIN TRAP}

The present invention relates to a drain trap for urinals.

In Fig. 12 of Patent Document 1, a conventional drainage trap for a urinal is disclosed. This urine drain trap is formed in the form of a cartridge, and has a lid part, a main body part, and a partition wall part. The urine drain trap is inserted in a circular opening provided in the lower end of the foot of the urinal and attached to the urinal. The cover part is circular in plan view. The cover part is provided with an inlet port through which urine flowing down along the foot surface flows. The main body portion has a cylindrical side wall portion extending downward from the outer periphery of the lid portion, a bottom portion formed continuously at the lower end of the side wall portion, and an outlet through which stored urine flows first. The partition wall portion extends downward from the lower surface of the inner side than the outer periphery of the lid portion, and is formed by providing a gap between the bottom portion. A folded portion extending laterally from the lower end of the partition wall toward the inlet side is formed. The retracted portion is an inclined surface rising in the tip direction.

In the main body portion, a first region formed below the inlet and above the retracted portion by the partition and the retracted portion, a second region provided with the outlet, and a third region formed below the retracted portion and above the bottom portion. It is divided into The outlet port is opened above the lower end of the partition wall part. The first region and the second region are communicated by the third region. In the first region, a seal liquid which is nonaqueous and lighter in specific gravity than urine is injected, and a seal layer is formed above the stored urine.

In addition, FIG. 1 of Patent Document 1 discloses another conventional urinal drain trap. This urinal drain trap is also formed in the form of a cartridge, and has a lid part, a main body part, and a partition wall part. The urine drain trap is inserted into the opening provided in the lower end of the foot of the urinal and attached to the urinal. The cover part is circular in plan view. The main body portion has a cylindrical side wall portion, a bottom portion formed continuously at the lower end of the side wall portion, and an outlet port through which stored urine is first. An inlet through which urine flowed down along the foot surface is formed between the periphery of the lid and the side wall of the body. The partition wall portion extends downward from the lower surface of the inner side than the outer periphery of the lid portion, and is formed by providing a gap between the bottom portion. The partition walls have a cylindrical shape with an open bottom.

The body part is partitioned into the 1st area | region formed in the outer side of the partition wall part, and the 2nd area | region formed inside by the partition wall part. The first region and the second region communicate with each other by a third region formed below the lower end of the partition wall and above the bottom. In the first region, a real liquid which is non-aqueous and lighter in specific gravity than urine is injected, and a real layer is formed above the stored urine.

The inlet port is related to the position where urine enters from the first region. The outlet port is erected from the bottom of the main body portion in the second region and is formed at the upper end of the cylindrical outlet tube arranged at the concentric position with the partition wall portion.

In these conventional urinal drain traps, the odor of the urine stored in the main body portion can be prevented from dissipating outward from the inlet port by the seal layer. In addition, the backflow of the odor from the drainage channel communicated to the downstream side can be blocked by the urine stored in the main body. For this reason, the urinal with the drain trap for a urinal can be used satisfactorily without releasing an odor from an inflow port into a toilet, even if washing water is not used at all.

Patent Document 1: Japanese Patent No. 3515785

However, in the urine drainage trap disclosed in FIG. 12 of Patent Document 1, urine flows from the first region to the third region in a sharp manner because the flow path of the first region is short. For this reason, the liquid liquid tends to be conveyed to the third region together with the urine flowing into the third region. Moreover, in the 3rd area | region, since the retracted part is the inclined surface which descend | falls gently to a downstream direction, there is little change of the up-down direction of a flow path, and the real liquid conveyed to the 3rd area piggybacks on the flow of urine, and it is a 2nd area of a downstream side. It is easy to be conveyed by. Since the specific liquid conveyed to the 2nd area is lighter in specific gravity than urine, the inside of the 2nd area is raised by the buoyancy. Thus, the liquid liquid conveyed to the 2nd area | region cannot return to a 1st area | region, and flows out from an outlet. For this reason, as a result of long-term use, the liquid liquid gradually flows out of the outlet, so that the liquid liquid decreases and the seal layer decreases. If the thread layer becomes thin, there is a fear that the smell of stored urine may diverge from the inlet.

In addition, in the drain trap for urinals disclosed in Fig. 1 of Patent Document 1, the outflow pipe is disposed at the concentric position with the partition wall portion, and the upward flow path of the urine in the second region is the outer surface of the outflow pipe and the partition wall. It is formed with a fixed space | interval with the inner side surface of a part. Since urine stays in this part, it is easy to attach a gel urine stone. If the distance between the outer surface of the outflow pipe and the inner surface of the partition wall is narrow, the rising urine may be blocked early due to deposition of gel-like urine deposited on the outer surface of the outflow pipe and the inner surface of the partition wall.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned conventional situation, and has been made to solve the problem of providing a drain trap for urinals capable of preventing the emission of odors over a long period of time, or discharging urine well over a long period of time. I am doing it.

The drainage trap for a urinal of the present invention is a cover portion having a inlet which is inserted into the opening provided in the lower end of the foot surface of the urinal, and the urine flowing down along the foot surface;

A main body portion having a side wall portion extending downwardly from an outer circumferential portion of the lid portion, a bottom portion continuously formed at a lower end of the side wall portion, and an outlet through which stored urine flows first;

It is provided inward from the outer periphery of the said cover part, and has a cavity-shaped partition wall part opened at a lower end with the space | interval with the bottom part of the said main body part,

The main body portion is partitioned into a first region formed on the outer side of the partition wall portion and a second region formed on the inner side by the partition portion, wherein the first region and the second region are lower than the lower end of the partition portion and the bottom portion. Is communicated by the 3rd area | region formed above,

As a drain trap for a urinal in which one of said 1st area | region or the said 2nd area | region is nonaqueous, lighter than specific gravity than urine, and the liquid liquid which forms the seal layer above the stored urine is injected,

The lower periphery of the partition wall portion is formed with a connecting portion that extends laterally toward one of the first region or the second region, and a retracted portion that extends upward is formed at the leading edge of the connecting portion.

The inlet is provided at a position at which urine flows from above between the partition wall portion and the retracted portion, and the outlet is within the other region of the first region or the second region, and the retracted portion is It is open above the upper end of a part, It is characterized by the above-mentioned.

In the urine drain trap, the urine flowing from the inflow port flows in from the upper portion between the partition wall portion and the folded portion through the seal layer. Since the lower end of the partition and the lower end of the retracted portion are connected by the connecting portion, the flow of urine changes from descending to rising in the region surrounded by the partition, the connecting portion and the retracted portion (hereinafter referred to as convection). Occurs. Due to the inflow of urine, the seal layer is stirred, and most of the seal liquid drawn in below the seal layer is wound around this convection. For this reason, the liquid liquid stays in the convection zone. When the inflow of urine disappears and the convection disappears, the liquid liquid remaining in the convective zone floats due to the buoyancy and joins the upper sea floor.

In addition, the force of the urine in the downward flow path that passes over the upper end of the retracted portion from the convection zone is attenuated by the force of the urine when entering the convection zone. For this reason, the liquid liquid which jumped on the flow of urine and passed through the upper end of the retracted portion from the convection station is conveyed to the intermediate position of the downward flow path, but it is difficult to convey to the third region. When the flow of urine disappears, the liquid liquid retained in this downward flow path floats due to its buoyancy and joins the upper chamber.

In this way, since the liquid is hardly conveyed to the third region by the flow of urine, the outflow of the liquid from the outlet provided downstream can be suppressed. For this reason, even a long-term use can reduce the reduction of the liquid solution, and the seal layer is less likely to become thin.

Therefore, the urine drain trap of the present invention can prevent the emission of odor over a long period of time.

The inlet may be associated with the partition wall. In this case, the urine flowing from the inlet is dispersed, and the force of the urine flowing into the main body is weakened. For this reason, stirring of the seal layer by the inflow of urine is suppressed, and it becomes difficult to pull in a liquid liquid below the seal layer. Thereby, the outflow of the real liquid can further be suppressed. In addition, since the urine flowing from the inlet flows down the surface of the partition wall portion, stirring of the seal layer is suppressed. This also suppresses the outflow of the liquid solution. Therefore, the seal layer is less likely to be thin, and odor emission can be prevented.

The retracted portion may be provided at regular intervals from the partition wall portion. In this case, since a constant gap is formed between the retracted portion and the partition wall portion, convection can be generated in the entire convection region. For this reason, since the liquid liquid which jumps on the flow of urine and passes through the upper end of a retracted part from a convection area can be reduced, the outflow of liquid liquid can be suppressed. Moreover, even if the gel-like urine stones adhere to the inner surface of the convection zone, the gel-like urine stones are difficult to deposit unevenly in the convection zone. For this reason, gel-like urine accumulates early in a specific location, and convection does not occur at that location, and it can suppress that a liquid liquid flows out. Therefore, the seal layer is less likely to be thin, and odor emission can be prevented.

The retracted portion may extend beyond a central height between the distal end portion of the connecting portion and the upper surface of the seal layer. In this case, since convection can be reliably formed in the convection region, the liquid liquid drawn in below the actual layer is wound around the convection in the convection region and stays in the convection region. In addition, since the upper end of the retracted portion is disposed at a high position in the first region, it is possible to reduce the actual liquid passing over the upper end of the refolded portion from the convection zone. For this reason, the outflow of the real liquid can be suppressed. Therefore, the seal layer is less likely to be thin, and odor emission can be prevented.

The upper end of the retracted portion can be lower than the lower surface of the seal layer. In this case, when urine flows out from the convection region over the upper end of the refolded portion and flows out to the downstream side, the introduction of the liquid liquid from the seal layer can be suppressed. For this reason, the outflow of the real liquid can be suppressed. Therefore, the seal layer is less likely to be thin, and odor emission can be prevented.

The retracted portion may be provided at a central position between the partition wall portion and the side wall portion. In this case, the distance between the partition wall portion and the retracted portion and the space between the refolded portion and the sidewall portion are the same, so that gel urine stones do not accumulate early in a specific location, and clogging due to the deposition of the gel urine stones is prevented. It can be suppressed.

In addition, the drain trap for urinals of the present invention, the cover portion having a inlet which is introduced into the opening provided in the lower end of the foot surface of the urinal, and the urine flowed down along the foot surface;

A main body portion having a side wall portion formed to extend downward from an outer peripheral portion of the lid portion, a bottom portion continuously formed at the lower end of the side wall portion, and an outlet through which stored urine is first-class;

It is provided inward from the outer periphery of the said cover part, extends downward from the closed upper end, and provides the space | interval with the bottom part of the said main body part, and has a cavity-shaped partition wall part which opened the lower end,

The main body portion is partitioned into a first region formed on the outer side of the partition wall portion and a second region formed on the inner side by the partition portion, wherein the first region and the second region are lower than the lower end of the partition portion and the bottom portion. It communicates with the 3rd area | region formed above and

The first region is a drain trap for urinals which is non-aqueous, has a specific gravity less than that of urine, and is injected with a liquid solution that forms a seal layer above the stored urine.

The inlet is connected to the position where the urine flows from above to the first region,

The said outlet port is formed in the 2nd area | region from the bottom part of the said main-body part, and is formed in the upper end of the outflow pipe arrange | positioned at the position which deviated to one direction in the said partition wall part in plan view.

In the drain trap for urinals, since the outflow pipe is disposed at a position deviated to one side in the partition wall in plan view, the gap between the outer surface of the outflow pipe and the inner surface of the partition wall in the other side in the partition wall in plan view is enlarged. can do. For this reason, even if gel-like urine stones are deposited on the outer surface of the outflow pipe and the inner surface of the partition wall portion, it is possible to make it difficult to block the upward flow path formed by being surrounded by the outer surface of the outlet pipe and the inner surface of the partition wall portion.

Therefore, the urine drainage trap of the present invention can discharge urine well over a long period of time.

When viewed from the horizontal cross section of the second region, the flow path area of the outflow pipe can be made larger than the flow path area of the upward flow path formed surrounded by the outer surface of the outflow pipe and the inner surface of the partition wall portion. In this case, since the flow rate of the urine flowing through the outflow pipe is larger than the flow rate of the urine flowing through the rising flow path, it is possible to prevent the overflow pipe from becoming full due to the urine flowing from the rising flow path. For this reason, the siphon action which arises by becoming full in the outflow pipe can be prevented. That is, the occurrence of the siphon action allows the urine to be retained in the urine drain trap to be discharged, thereby preventing the water rod from being broken. Further, even if gel-like urine stones are deposited on the inner side of the downstream side of the outflow pipe, the situation in which the outflow pipe becomes full due to the urine flowing from the upward flow passage can be delayed. For this reason, this urine drain trap can be used favorably over a long period of time.

The partition wall portion may be formed extending from the center portion of the main body portion toward the inner side surface of the side wall portion when viewed in a horizontal cross section. In this case, the flow path area of the outlet pipe can be made larger. For this reason, it is possible to prevent the overflow pipe from becoming full due to the urine flowing from the upward flow passage and to prevent the occurrence of siphon action. In addition, gel urine stones are deposited on the inner side of the downstream side of the outflow pipe, whereby the flow path area is narrowed, and the situation in which the outflow pipe becomes full due to urine flowing from the upward flow path can be further slowed down. Therefore, this urinal drain trap can be used favorably over a long period of time.

The partition wall portion is formed in a cylindrical shape, the outlet pipe is formed in a semi-cylindrical shape, it may be arranged to approach the inner surface of the partition wall portion of the arc-shaped outer surface. In this case, the flow path area of the outflow pipe can be enlarged while expanding the distance between the outer surface of the outflow pipe and the inner surface of the partition wall on the other side in the partition wall in plan view. For this reason, the outflow flow rate of urine from an outflow pipe can fully be ensured, and discharge of urine can be performed favorably.

The dimension of the up-down direction of the said 3rd area | region can be formed larger than the dimension of the lateral direction as seen from the up-down center cross section of the urging | falling flow path of the urine formed in the said 1st area | region, and the said rising path. In this case, since the dimension in the up-down direction can be largely formed in the third region where gel-like urine stones tend to be deposited, even if gel urine stones are deposited in the third region, it is possible to prevent the third region from being blocked early. Can be. For this reason, discharge of urine can be performed favorably over a long period of time.

The urine drain trap may be formed in the form of a cartridge to which a drain pipe is connected and detachably attached to a concave portion which is opened upward at the lower end of the foot of the urinal. In this case, it can be replaced for each cartridge when a decrease in the actual liquid or a blockage due to the deposition of gel-like urine stones occurs. In this way, maintenance can be performed easily.

In addition, since the clogging caused by the deposition of gel-like urine stones is suppressed in the urine drain trap, the replacement frequency of the cartridge can be reduced.

The locking convex portion 12F can be locked to the locking concave portion 20A by rotating the drain trap 10 for the urinal inserted into the storage container 20 by a predetermined angle around the shaft. In this manner, the cartridge-type urinal drain trap 10 can be detachably attached to the storage container 20.

In the storage container 20, the packing 22 is externally wound on the outer surface of the locking member 21, and is inserted from above from the opening 2A formed at the lower end of the foot surface 2 of the urinal 1. have. The shade 21B of the locking member 21 is locked to the upper surface of the peripheral portion of the opening 2A.

In this way, the container 20 is attached to the opening 2A by pinching the periphery of the opening 2A by the shade 21B and the fastening member 23 of the locking member 21. The storage container 20 has a connecting tube 24 extending from the lower corner. The storage container 20 is connected to the drain pipe 4 drawn out to the wall surface W via the connection pipe 24.

The urine drainage trap 10 formed in the form of a cartridge is provided with the cover part 11, the main body part 12, and the partition wall part 13. As shown in FIG. The outer shape of the cover part 11 is circular shape. The lid portion 11 is fitted into an opening formed by the locking member 21 of the storage container 20, that is, an opening provided at the lower end of the foot surface 2 of the urinal 1. Packing P is inserted in the annular recess formed in the outer peripheral end surface of the cover part 11. For this reason, the inner side surface of the opening formed by the locking member 21 and the outer side surface of the lid part 11 are joined watertightly. For this reason, the urine flowing down along the foot surface 2 of the urinal 1 flows to the upper surface of the cover part 11. 11 A of inlets through which the urine which flowed down along the foot surface 2 of the urinal 1 inflows are provided in the lid part 11.

The main body part 12 has the side wall part 12A, the bottom part 12B, and the outlet port 12C. The side wall part 12A is cylindrical and extends downward from the outer periphery of the lid part 11. The outer periphery of the lid portion 11 and the upper end of the side wall portion 12A are bonded without a gap. A plurality of locking projections 12F are formed in the middle portion of the outer side surface of the side wall portion 12A. As described above, the locking convex portion 12F is locked to the locking recess 20A formed on the inner surface of the storage container 20, whereby the cartridge type urinal drain trap 10 is stored in the storage container 20. It is attached detachably. The bottom part 12B is formed continuously in the lower end of the side wall part 12A.

The partition part 13 is cylindrical in shape, is provided inward from the outer peripheral end of the cover part 11, extends downward from the closed upper end, and provides a space | interval with the bottom part 12B of the main-body part 12, It is an open cavity. The partition part 13 is provided coaxially with the cover part 11. 11 A of inflow openings divided into several parts along the outer side surface of the partition part 13 are arrange | positioned at the cover part 11 in ring shape.

The main body part 12 is partitioned by the partition part 13 into the 1st area | region 31 formed in the outer side of the partition wall part 13, and the 2nd area | region 32 formed in the inside. The 1st area | region 31 and the 2nd area | region 32 are communicated by the 3rd area | region 33 formed below the lower part of the partition part 13, and above the bottom part 12B of the main-body part 12. FIG. In the first region 31, a liquid solution which is non-aqueous, has a specific gravity less than that of urine, and forms the seal layer S above the stored urine.

The partition portion 13 forms a ring-shaped connecting portion 14 that extends laterally toward the first region 31 at the outer periphery of the lower end. The connecting portion 14 forms a cylindrical retracted portion 15 extending upwardly at the tip peripheral edge. The retracted portion 15 has a constant distance from the partition wall 13. Moreover, the folded part 15 is provided in the center position between the partition part 13 and the side wall part 12A. In other words, the folded portion 15, the partition portion 13, and the main body portion 12 are arranged coaxially. In addition, the upper end of the folded part 15 is extended upwards to the position lower than the lower surface of the seal layer S formed above the urine stored in the main-body part 12 in the 1st area | region 31. As shown in FIG. Moreover, the folded part 15 extends more than the center height between the front-end | tip peripheral part of the connection part 14, and the upper surface of the seal layer S. FIG.

The outlet port 12C is formed in the upper end of the outlet pipe 12D erected from the bottom 12B of the main body part 12 in the second region 32. In addition, the outlet 12C is opened above the upper end of the folded portion 15. The outflow pipe 12D is formed in the semicylindrical shape, and is arrange | positioned so that the outer side of circular arc shape may contact the inner side surface of the partition part 13. That is, the outflow pipe 12D is arrange | positioned in the position which shifted to one side in the partition 13 in planar view.

The lower part of the outflow pipe 12D is bent in the side wall part 12A direction along the bottom part 12B of the main body part 12. The discharge port 12E is provided in the bottom part 12B at the downstream end of the outflow pipe 12D. The cartridge type urinal drain trap 10 is attached to the storage container 20 so that the discharge port 12E may be disposed at a position upstream of the connecting pipe 24 of the storage container 20.

The dimension X in the vertical direction of the third region 33 is viewed from the vertical central section of the downward flow path D of the urine formed in the first region 31 and the upward flow path U of the urine formed in the second region. It is formed larger than the dimensions (Y, Z) in the transverse direction at the time.

In the urine drain trap 10 having such a configuration, the urine flowing from the inlet 11A flows in from the upper portion between the partition 13 and the folded portion 15 through the seal layer S. As shown in FIG. Then, in the area surrounded by the partition 13, the connecting portion 14, and the retracted portion 15 (hereinafter referred to as the convection zone T), the flow of urine changes from descending to rising, and convection occurs. . Due to the inflow of urine, the seal layer S is stirred, and most of the seal liquid drawn in below the seal layer S is wound around this convection. For this reason, the actual liquid stays in the convection zone T. When the inflow of urine disappears and the convection disappears, the liquid liquid remaining in the convective region T floats due to its buoyancy and joins the upper seal layer S above.

Moreover, the force of the urine in the downward flow path D which passes over the upper end of the retracted part 15 from the convection area T toward the 3rd area | region 33, when it flows into the convection area T It is attenuating compared to the force of urine. For this reason, the liquid liquid which jumped on the flow of urine and passed over the upper end of the retracted part 15 from the convection area T is conveyed to the intermediate position of the downward flow path D, but to the 3rd area | region 33 It is difficult to be returned. When the flow of urine disappears, the liquid liquid retained in the downward flow path D floats due to the buoyancy and joins the upper seal layer S above.

In this way, since the liquid liquid cannot be conveyed to the third region 33 by the flow of urine, the outflow of the liquid liquid from the outlet 12C provided downstream can be suppressed. For this reason, reduction of a real liquid can be suppressed also by long-term use, and the real layer S is hard to become thin.

Therefore, the drain trap 10 for urinals of Example 1 can prevent the emanation of an odor over a long period of time.

In addition, since the inlet 11A is formed in a ring shape divided into a plurality of parts along the outer surface of the partition wall 13, the urine flowing from the inlet 11A is dispersed, and the urine flowing into the main body 12 is distributed. Will weaken. For this reason, stirring of the seal layer S by the inflow of urine is suppressed, and it becomes difficult to pull in a liquid liquid below the seal layer S. FIG. Thereby, the outflow of the real liquid can further be suppressed. In addition, since the urine flowing from the inlet 11A flows down the outer surface of the partition 13, stirring of the seal layer S is suppressed. This also suppresses the outflow of the liquid solution. Therefore, the seal layer S is less likely to be thin, and odor emission can be prevented.

Moreover, since the retracted part 15 is provided at regular intervals with the partition wall part 13, it can generate convection in the whole convection area T. As shown in FIG. For this reason, the liquid liquid which rides on the flow of urine and passes the upper end of the retracted part 15 from the convection area T can be reduced. Therefore, the outflow of the real liquid can be suppressed. Moreover, even if gel-like urine stones adhere to the inner surface of the convection zone T, the gel-like urine stones do not unevenly deposit in the convection zone T. For this reason, gel-like urine stones accumulate early in a specific location, and it can suppress that a liquid liquid flows out because convection does not arise in the location. Therefore, the seal layer S is less likely to be thin, and odor emission can be prevented.

In addition, since the retracted portion 15 extends beyond the center height between the distal end portion of the connecting portion 14 and the upper surface of the seal layer S, convection is reliably formed in the convection region T, thus forming the seal layer. The actual liquid drawn in from below (S) can be wound around the convection in the convection zone T so that it stays in the convection zone. Moreover, since the upper end of the folded part 15 is arrange | positioned in the position where the 1st area | region 31 is high, the real liquid which passes over the upper end of the folded part 15 from the convection area T can be reduced. For this reason, the outflow of the real liquid can be suppressed. Therefore, the seal layer S is less likely to be thin, and odor emission can be prevented.

In addition, since the upper end of the folded portion 15 is formed lower than the lower surface of the seal layer S, when urine flows out from the convection region T to the downstream side of the folded portion 15, the sealed layer The pulling in of the real liquid from (S) can be suppressed. For this reason, the outflow of the real liquid can be suppressed. Therefore, the seal layer S is less likely to be thin, and odor emission can be prevented.

In addition, since the retracted portion 15 is provided at a central position between the partition wall portion 13 and the side wall portion 12A, the convection region T formed between the partition wall portion 13 and the retracted portion 15 is provided. , And gel urine stones do not accumulate prematurely at a specific location of the down flow path D formed between the folded portion 15 and the side wall portion 12A, and the blockage due to the deposition of the gel urine stones can be suppressed. Can be.

In addition, the dimension X of the up-down direction of the 3rd area | region 33 is the vertical center cross section of the downward flow path D of the urine formed in the 1st area | region 31, and the upward flow path U of the urine formed in the 2nd area | region. It is formed larger than the dimension (Y, Z) of the lateral direction at the time of viewing. That is, since the dimension of the up-down direction can be formed large in the 3rd area where gel-like urine stones are easy to deposit, the 3rd area | region 33 can make it hard to be clogged by the deposit of gel-like urine stones. For this reason, urine can be discharged favorably.

In addition, since the urine drain trap 10 is formed in the form of a cartridge, it can be replaced for each cartridge when a blockage occurs due to a decrease in the actual liquid or deposition of urine stones. For this reason, maintenance can be performed easily. In addition, since the clogging caused by the deposition of gel-like urine stones is suppressed in the urine drain trap, the replacement frequency of the cartridge can be reduced.

In the urine drain trap 10 having such a configuration, the partition wall portion 13 is formed in a cylindrical shape, the outlet pipe 12D is formed in a semi-cylindrical shape, and the arc-shaped outer surface of the urine drain trap 10 has a partition wall portion ( By arrange | positioning in contact with the inner side surface of 13, the outflow pipe 12D is arrange | positioned in the position which shifted to the one side in the partition 13 in planar view. For this reason, the gap between the outer side surface of the outflow pipe 12D and the inner side surface of the partition wall part 13 can be enlarged in the other side in the partition wall part 13 in plan view. Therefore, even if gel-like urine is deposited on the outer side surface of the outflow pipe 12D and the inner side surface of the partition wall portion 13, the rise formed by being surrounded by the outer side surface of the outlet pipe 12D and the inner side surface of the partition wall portion 13. It may be difficult to block the flow path U.

Therefore, the urine drain trap 10 of Example 1 can discharge urine well over a long period of time.

On the other side of the partition wall 13 in plan view, the flow path cross-sectional area of the outlet pipe 12D is enlarged while enlarging the distance between the outer surface of the outlet pipe 12D and the inner surface of the partition wall 13. can do. For this reason, the outflow flow rate of urine from the outflow pipe 12D can fully be ensured, and discharge of urine can be performed favorably.

<Example 2>

In the urine drain trap 110 of Example 2, as shown in FIG. 5, the main-body part 112 is directly attached to the lower end part of the foot surface 2 of the urinal 1. The locking member 21 is connected to the upper end of the main body 112. The main body part 112 is inserted above the opening 2A formed in the lower end part of the foot surface 2 of the urinal 1, and the shading part 21B of the locking member 21 is the upper surface of the peripheral part of the opening 2A. Depends on A screw portion is formed on the upper side of the outer side of the main body portion 112. A ring-shaped fastening member 23 whose outer surface is wound from below the main body 112 and whose upper surface is locked to the lower surface of the periphery of the opening 2A is fastened to a screw formed on the outer surface of the main body 112. In this manner, the main body portion 112 is attached to the opening 2A by sandwiching the peripheral portion of the opening 2A by the shade 21B and the fastening member 23 of the locking member 21.

In addition, the main body 112 has a connecting pipe 124 extending from the lower corner. The outflow pipe 112D standing in the 2nd area | region 32 is connected to the upstream end of the connection pipe 124. As shown in FIG. The outlet 112C is formed in the upper end of the outlet pipe 112D. The outlet 112C is opened above the upper end of the folded portion 15. The outflow pipe 112D is formed in semi-cylindrical shape, and the outer side of circular arc shape is arrange | positioned in contact with the inner side surface of the partition part 13. As shown in FIG. That is, the outflow pipe 112D is arrange | positioned in the position which shifted to one side in the partition 13 in plan view. The lower end of the connecting pipe 124 is connected to the drain pipe 4 drawn out to the wall surface W. As shown in FIG.

In addition, the lid part 11 is attached to the main body part 112 so that attachment or detachment is possible. For this reason, when the blockage by gelatinous urine stone accumulate | stored in the main-body part 112, etc., the cover part 11 can be removed and the cause of a blockage can be removed. The other structure is the same as that of Example 1, the same code | symbol is attached | subjected about the same structure, and detailed description is abbreviate | omitted.

Also in the urine drain trap 110 having such a configuration, similarly to the urine drain trap 10 of the first embodiment, most of the liquid liquid drawn in below the seal layer S by the inflow of urine is convection. It is wound around the convection which occurred in the station T, and stays in the convection station T. For this reason, when the inflow of urine disappears, the liquid liquid which stayed in the convection area T floats by the buoyancy and joins the upper seal layer S above. In addition, the liquid liquid which passed over the upper end of the retracting part 15 from the convection area | region T is conveyed to the intermediate position of the downward flow path D, and is hard to be conveyed to the 3rd area | region 33. FIG. When the flow of urine disappears, the liquid liquid retained in the downward flow path D floats due to the buoyancy and joins the upper seal layer S above. In this way, since the liquid liquid is hardly conveyed to the third region 33 by the flow of urine, the outflow of the liquid liquid from the outlet 12C provided downstream therefrom can be suppressed. For this reason, reduction of a real liquid can be suppressed also by long-term use, and the real layer S is hard to become thin.

Therefore, the urine drain trap 110 of Example 2 can also prevent odor emission over a long period of time.

In addition, in the urine drain trap 110, the partition 13 is formed in a cylindrical shape, and the outlet pipe 112D is formed in a semi-cylindrical shape as in the urine drain trap 10 of the first embodiment. Since the arc-shaped outer surface is disposed in contact with the inner surface of the partition wall 13, the outflow pipe 112D is disposed at a position deviated to one side in the partition wall 13 in plan view. For this reason, the gap between the outer side surface of the outflow pipe 112D and the inner side surface of the partition wall part 13 can be enlarged in the other side in the partition wall part 13 by planar view. Therefore, the upward flow path U of the urine formed between the outer surface of the outlet pipe 112D and the inner surface of the partition wall 13 is the outer surface of the outlet pipe 112D and the inner surface of the partition wall 13. Even if urine-like urine stones are deposited, it may be difficult to be blocked.

Therefore, the urine drain trap 110 of Example 2 can also discharge urine well over a long period of time.

<Example 3>

In the urine drain trap 210 of Example 3, as shown in FIG. 6, the outflow pipe 212D is cylindrical and is formed coaxially with the side wall part 212A of the main-body part 212. As shown in FIG. The outflow pipe 212D is also coaxially located with the partition wall 13. For this reason, the upward flow path U is formed between the partition walls 13 around the outflow pipe 212D. In the bottom part 212B of the main-body part 212, the discharge port 212E which goes upstream of the connecting pipe 24 of the storage container 20 is formed in the center part. The other structure is the same as that of Example 1, the same code | symbol is attached | subjected about the same structure, and detailed description is abbreviate | omitted.

Also in the urine drain trap 210 having such a configuration, similar to the urine drain trap 10 of the first embodiment, most of the liquid liquid drawn in below the seal layer S by the inflow of urine is convection. It is wound around the convection created in the station (T), and stays in the convection station (T). For this reason, when the inflow of urine disappears, the liquid liquid which stayed in the convection area T floats by the buoyancy and joins the upper seal layer S above. In addition, the liquid liquid which passed over the upper end of the retracting part 15 from the convection area | region T is conveyed to the intermediate position of the downward flow path D, and is hard to be conveyed to the 3rd area | region 33. FIG. When the flow of urine disappears, the liquid liquid retained in the downward flow path D floats due to the buoyancy and joins the upper seal layer S above. Thus, since the liquid liquid is hard to be conveyed to the 3rd area | region 33 by the flow of urine, the outflow of the liquid liquid from the outlet 212C provided downstream from that can be suppressed. For this reason, reduction of a real liquid can be suppressed also by long-term use, and the real layer S is hard to become thin.

Therefore, the urine drain trap 210 of Example 3 can also prevent odor emission for a long time.

<Example 4>

The urine drain trap 310 of Example 4 is provided with the cover part 311, the main body part 312, and the partition wall part 313, as shown in FIG. The main body 312 has a side wall 312A, a bottom 312B, and an outlet 312C. The side wall portion 312A is cylindrical in shape, and a band-shaped convex portion 312D is formed in the middle portion of the outer surface. The main body 312 is directly attached to the lower end of the foot surface 2 of the urinal 1 by the locking member 321. The locking member 321 includes a cylindrical cylindrical portion 321A surrounding the upper portion of the main body portion 312, a ring-shaped sunshade portion 321B that is continuous to an upper end of the cylindrical portion 321A and spreads outward, It has the ring-shaped recessed part 321C continuous to the lower end of cylindrical part 321A, and engaging with convex part 312D. In addition, the locking member 321 is provided with a semi-circular arc-shaped locking portion 321D in which the peripheral portion of the opening 2A formed in the lower end of the foot surface 2 of the urinal 1 is sandwiched between the shade portion 321B. Have The locking portion 321D is elastically movable, elastically moves inward, passes through the opening 2A from above, and moves outward after passage. In this way, the locking portion 321D is locked to the lower surface of the peripheral edge of the opening 2A. The packing 22 is externally wound between the shade 321B and the locking portion 321D.

The side wall part 312A is provided with the outflow opening 312C which opens above the upper end of the folded part 315 mentioned later. The main body 312 is provided with a connecting pipe 324 extending laterally from the outlet 312C. The urine drain trap 310 is connected to the drain pipe 4 drawn out to the wall surface W by the connecting pipe 324 extending laterally from the top.

The outer shape of the cover part 311 is circular shape. The cover part 311 has an opening formed by the locking member 321 which attaches the main body 312 to the lower end of the foot 2 of the urinal 1, that is, the lower end of the foot 2 of the urinal 1. It is penetrated by the opening provided. The packing P is inserted in the annular recess formed in the outer peripheral end surface of the cover part 311. For this reason, the inner side surface of the opening formed by the locking member 321 and the outer side surface of the lid part 311 are joined watertightly. For this reason, the urine flowing down along the foot surface 2 of the urinal 1 flows on the upper surface of the cover part 311. The inlet port 311A through which the urine flowing down along the foot surface 2 of the urinal 1 flows in the lid part 311 is provided.

The partition part 313 is cylindrical, is provided inward from the outer peripheral end of the cover part 311, and the lower end is provided in the space | interval with the bottom part 312B of the main body part 312, and is opened. The partition part 313 is provided coaxially with the cover part 311. In the cover part 311, the inlet port 311A divided into multiple numbers along the inner surface of the partition part 313 is arrange | positioned in ring shape.

The body part 312 is partitioned into the 1st area | region 331 formed in the outer side of the partition wall part 313, and the 2nd area | region 332 formed in the inside by the partition wall part 313. As shown in FIG. The 1st area | region 331 and the 2nd area | region 332 are communicated by the 3rd area | region 333 formed below the lower part of the partition part 313, and above the bottom part 312B of the main-body part 312. As shown in FIG. In the second region 332, a liquid solution which is non-aqueous, has a specific gravity less than that of urine, and forms the seal layer S above the stored urine.

A ring-shaped connecting portion 314 extending laterally toward the second region 332 is formed at the inner circumferential portion of the bottom of the partition 313. At the leading edge of the connecting portion 314, a cylindrical folded portion 315 extending upward to the height of the middle portion of the partition portion 313 is formed. The retracted portion 315 has a predetermined distance from the partition wall portion 313. In other words, the folded portion 315 and the partition wall portion 313 are arranged coaxially. In addition, the upper end of the retracted portion 315 is formed upward in the second region 332 to a position lower than the lower surface of the seal layer S formed above the urine stored in the main body 312.

In the urine drain trap 310 having such a configuration, the urine flowing from the inlet 311A flows in from the upper portion between the partition wall 313 and the folded portion 315 through the seal layer S. As shown in FIG. Then, in the convection zone T, which is an area surrounded by the partition wall portion 313, the connection portion 314, and the retracted portion 315, the flow of urine is changed from the descending to the rising, and convection occurs. Due to the inflow of urine, the seal layer S is stirred, and most of the seal liquid drawn in below the seal layer S is wound around this convection. For this reason, the actual liquid stays in the convection zone T. When the inflow of urine disappears and the convection disappears, the liquid liquid remaining in the convective region T floats due to its buoyancy and joins the upper seal layer S above.

Moreover, the force of the urine in the downward flow path D which passes over the upper end of the retracted part 315 from the convection area T toward the 3rd area | region 333, when the inflow into the convection area T is carried out. It is attenuating compared to the force of urine. For this reason, the liquid liquid which jumped on the flow of urine and passed over the upper end of the retracted part 315 from the convection area T is conveyed to the intermediate position of the downward flow path D, but to the 3rd area | region 33 It is difficult to be returned. When the flow of urine disappears, the liquid liquid convection in this downward flow path D floats by the buoyancy and joins the upper seal layer S above.

Thus, since the liquid liquid is hard to be conveyed to the 3rd area | region 333 by the flow of urine, the outflow of liquid liquid can be suppressed from the outlet 312C provided downstream from it. For this reason, reduction of a real liquid can be suppressed also by long-term use, and the real layer S is hard to become thin.

Accordingly, the urine drainage trap 310 of the fourth embodiment can also prevent odor emission over a long period of time.

In addition, since the inlet port 311A is provided along the inner side surface of the partition wall portion 313 and on a ring divided into a plurality, the urine flowing from the inlet port 311A is dispersed and the force of the urine flowing into the main body portion 312 is achieved. This weakens. For this reason, stirring of the seal layer S by the inflow of urine is suppressed, and it becomes difficult to pull in a liquid liquid below the seal layer S. FIG. Thereby, the outflow of the real liquid can further be suppressed. In addition, since the urine flowing from the inlet 11A flows down the inner surface of the partition 313, the stirring of the seal layer S is suppressed. This also suppresses the outflow of the liquid solution. Therefore, the seal layer S is less likely to be thin, and odor emission can be prevented.

In addition, since the retracted portion 315 is provided at regular intervals from the partition wall portion 313, it is possible to generate convection in the entire convection region T. For this reason, the liquid liquid which rides on the flow of urine and passes the upper end of the retracted part 315 from the convection area T can be reduced. Therefore, the outflow of the real liquid can be suppressed. Moreover, even if urine in the gel adheres to the inner surface of the convection zone T, the gel-like urine stone does not deposit unevenly in the convection zone T. For this reason, gel-like urine stones accumulate early in a specific location, and it can suppress that a liquid liquid flows out because convection does not arise in the location. Therefore, the seal layer S is less likely to be thin, and odor emission can be prevented.

In addition, since the upper end of the retracted portion 315 is formed lower than the lower surface of the seal layer S, when urine flows out from the convection region T over the upper end of the retracted portion 315 and flows downstream, The pulling in of the real liquid from (S) can be suppressed. For this reason, the outflow of the real liquid can be suppressed. Therefore, the seal layer S is less likely to be thin, and odor emission can be prevented.

In addition, since the downward flow path D having a large flow path cross-sectional area is formed inside the retracted portion 315, gel urine stones do not accumulate at an early stage, and clogging due to the deposition of gel urine stones can be suppressed. have.

<Example 5>

In the urine drain trap 410 of the fifth embodiment, as illustrated in FIG. 4B, the outflow pipe 412D is formed in a cylindrical shape, and the outer surface of the outflow pipe 412D has a partition wall portion ( It is arrange | positioned in contact with the inner side of 13). That is, the outflow pipe 412D is arrange | positioned in the position which shifted to one side in the partition 13 in planar view. The other structure is the same as that of Example 1, the same code | symbol is attached | subjected about the same structure, and detailed description is abbreviate | omitted.

In the urine drain trap 410 having such a configuration, the gap between the outer surface of the outlet pipe 412D and the inner surface of the partition wall 13 can be enlarged on the other side in the partition wall 13 in plan view. Can be. Therefore, the upward flow path U of the urine formed between the outer surface of the outlet pipe 412D and the inner surface of the partition wall 13 is the outer surface of the outlet pipe 412D and the inner surface of the partition wall 13. Even if urine-like urine stones are deposited, it may be difficult to be blocked.

Therefore, the urine drainage trap 410 of Example 5 can also discharge urine well over a long period of time.

<Example 6>

The urine drainage trap 510 of Example 6 is provided with the cover part 511, the main body part 512, and the partition wall part 513, as shown to FIG. The lid 511 has an inlet 511A through which urine flowed down along the foot surface 2 of the urinal 1. The main body portion 512 has a side wall portion 512A, a bottom portion 512B, and an outlet 512C. A plurality of locking protrusions 512F are formed in the middle portion of the outer side surface of the side wall portion 512A.

The partition wall part 513 is a cavity shape extended toward the side wall part 512A from the center part of the main body part 512 in the horizontal cross section. Moreover, the outer side surface of the partition wall part 513 extended toward the side wall part 512A is in contact with the inner side surface of the side wall part 512A. In addition, the partition wall part 513 has the semicircular annular shape of the center part side of the main-body part 512 in the horizontal cross section, and the inflow port divided into the some part by the cover part 512 along the outer surface of this part ( 511A) is arranged. In addition, the internal space of the partition 513 has a semicircular shape at the center of the main body 512 when viewed in a horizontal cross section, and the diameter of the semicircle is a short side, and is rectangular toward the side wall portion 512A from this short side. It is formed into a phase.

In the main body 512, the partition 513 is partitioned into a first region 531 formed outside the partition 513 and a second region 532 formed inside. The first region 531 and the second region 532 communicate with each other by the third region 533 formed below the bottom of the partition 513 and above the bottom 512B of the main body 512. In the first region 531, a liquid solution which is non-aqueous, has a specific gravity less than that of urine, and forms the seal layer S above the stored urine.

The urine drainage trap 510 has the outer side surface from one outer side surface of the side surface in which the partition wall portion 513 extends from the center portion of the main body portion 512 toward the side wall portion 512A when viewed in a horizontal cross section. The folded portions 515 are formed at equal intervals from the inner side surface of the side wall portion 512A so as to connect them. The lower end of the retracted part 515 and the lower part of the partition wall part 513 are connected by the connection part 514. As shown in FIG. The upper end of the retracted portion 515 extends upward from the first region 531 to a position lower than the lower surface of the seal layer S formed above the urine stored in the main body 512. In addition, the retracted portion 515 extends beyond the center height between the leading edge of the connecting portion 514 and the upper surface of the seal layer S. FIG.

Outflow port 512C is formed in the 2nd area | region 532 in the upper end of the outflow pipe 512D set up from the bottom part 512B of the main-body part 512. As shown in FIG. In addition, the outlet 512C is opened above the upper end of the folded portion 515. The outlet pipe 512D has a rectangular opening cross section, and a horizontal cross sectional rectangle of the outer surface. This outflow pipe 512D is arrange | positioned so that the outer side of three directions may be in contact with the inner side of the part formed in the rectangular shape when the internal space of the partition part 513 sees in a horizontal cross section. That is, the outflow pipe 512D is arrange | positioned at the position which shifted to one side in the partition wall part 513 in plan view.

An upward flow path U is provided at a portion surrounded by the outer surface of the outflow pipe 512D and the inner surface of the partition wall part 513 without contacting the outer surface of the outflow pipe 512D. Is formed. In the horizontal cross section of the second region 532, the flow path area of the outflow pipe 512D is formed larger than the flow path area of the rising flow path U. As shown in FIG.

The lower part of the outflow pipe 512D is open downward. A discharge port 512E is provided at the bottom 512B at the downstream end of the outflow pipe 512D. A cartridge type urinal drain trap 510 is attached to the storage container 20 so that the discharge port 512E is disposed at a position upstream of the connecting pipe 24 of the storage container 20. The other structure is the same as that of Example 1, the same code | symbol is attached | subjected about the same structure, and detailed description is abbreviate | omitted.

Even in the urine drain trap 510 having such a configuration, since the outflow pipe 512D is disposed at a position biased to one side in the partition wall portion 513 in a plan view, the outer surface of the outflow pipe 512D The distance from the inner side surface of the partition 513 can be widened. Therefore, even if gel-like urine is deposited on the outer side surface of the outflow pipe 512D and the inner side surface of the partition wall portion 513, the rise formed by being surrounded by the outer side surface of the outlet pipe 512D and the inner side surface of the partition wall portion 513. It may be difficult to block the flow path U.

Therefore, the urine drainage trap 510 of Example 6 can discharge urine well over a long period of time.

In addition, when viewed from the horizontal cross section of the second region 532, the flow path area of the outflow pipe 512D is formed larger than the flow path area of the upward flow path U, so that the upward flow path U can flow. The flow rate of urine that can flow through the outflow pipe 512D is larger than the flow rate of urine. For this reason, it is possible to prevent the water discharge from being full due to the urine flowing from the upward flow path U inside the outflow pipe 512D. Thereby, the siphon action which arises by becoming full in the outflow pipe 512D can be prevented. That is, due to the siphon action, the urine to be kept in the urine drain trap 510 is discharged, and the water rod can be prevented from being broken. Further, even if gel-like urine is deposited on the inner side of the downstream side of the outflow pipe 512D, the situation in which the outflow pipe 512D becomes full due to the urine flowing from the upward flow path U can be delayed. For this reason, this urine drain trap 510 can be used favorably over a long period of time.

In addition, since the partition wall part 513 extends toward the side wall part 512A from the center part of the main body part 512 in the horizontal cross section, the flow path area of the outflow pipe 512D can be made larger. For this reason, the outflow pipe 512D can be prevented from becoming full due to the urine flowing in from the upward flow path U, and the occurrence of the siphon action can be prevented. In addition, it is possible to further slow down the situation where gel-like urine accumulates on the inner side surface of the downstream side of the outflow pipe 512D, the flow path area is narrowed, and the water flow is full due to the urine flowing out of the upward flow path in the outflow pipe 512D. Therefore, this urinal drain trap 510 can be used favorably over a long period of time.

In addition, since the lower part of the outflow pipe 512D opens downward, urine can be discharged directly from the outflow pipe 512D into the storage container 20. For this reason, the outflow pipe 512D can be prevented from becoming full due to the urine flowing in from the upward flow path U, and the occurrence of the siphon action can be prevented.

&Lt; Example 7 >

In the urine drain trap 560 of the seventh embodiment, as shown in FIGS. 11 and 12, in the urine drain trap 510 of the sixth embodiment, the partition wall portion 513 is formed in the side wall portion 512A. The part which contacts the side surface is formed integrally with the side wall part 512A, and the part which the outflow pipe 512D is in contact with the inner side surface of the partition wall part 513 is formed integrally with the partition wall part 513. As a result, the urine drain trap 560 can be easily manufactured and the consumption of raw materials can be reduced.

The upper end part of the outflow pipe 512D which forms the upward flow path U of this urine drain trap 560 is formed in R shape, is formed continuously in this R surface, and its vertical cross-sectional shape is a rough semicircular convex shape. Forming wealth. For this reason, when urine flows into the outflow pipe 512D from the upward flow path U, the upper end part of the outflow pipe 512D can be smoothly flown. The other structure is the same as that of Example 6, the same code | symbol is attached | subjected about the same structure, and detailed description is abbreviate | omitted.

Also in the urine drain trap 560 having such a configuration, the outflow pipe is equivalent to the structure in which the outflow pipe is arranged at a position in one side of the partition wall portion 513 in plan view, so that the outer surface and the partition wall portion of the outflow pipe. The distance from the inner side of 513 can be widened. Therefore, even if gel-like urine is deposited on the outer surface of the outlet pipe and the inner surface of the partition wall portion 513, the rising flow path U formed by being surrounded by the outer surface of the outlet pipe and the inner surface of the partition wall portion 513 is blocked. It can be difficult.

Therefore, the urine drainage trap 560 of Example 7 can discharge urine well over a long period of time.

In addition, when viewed from the horizontal cross section of the second region 532, the flow passage area of the portion corresponding to the outflow pipe is formed larger than the flow passage area of the rise passage U, so that the flow passage U can flow. The flow rate of urine is larger than the flow rate of urine that can flow to the portion corresponding to the outlet pipe. For this reason, the inside of the part corresponded to an outflow pipe can be prevented from becoming full by the urine which flows in from the upward flow path U. Thereby, the siphon action which arises by becoming full in the inside of the part corresponded to an outflow pipe can be prevented. That is, it is possible to prevent the urine to be discharged from the urine drain trap 560 and the water rod to be broken by the siphon action. Moreover, even if gel-like urine is deposited on the inner side of the downstream side of the portion corresponding to the outflow pipe, the inside of the portion corresponding to the outflow pipe is slowed down by the water flowing from the rising flow path U. Can be. For this reason, this urine drain trap 360 can be used favorably over a long period of time.

In addition, since the partition wall part 513 extends toward the side wall part 512A from the center part of the main body part 512 in the horizontal cross section, the flow path area of the part corresponded to an outflow pipe can be made wider. . For this reason, the inside of the part corresponded to an outflow pipe can be prevented from becoming full by the urine which flows in from the upward flow path U, and can prevent the occurrence of a siphon action. Further, gel urine stones are deposited on the inner side of the downstream side of the portion corresponding to the outflow pipe, whereby the flow path area is narrowed, and the inside of the portion corresponding to the outflow pipe becomes full due to the urine flowing from the rising flow path. You can slow it down. Therefore, this urinal drain trap 560 can be used favorably over a long period of time.

In addition, since the lower portion of the portion corresponding to the outflow pipe is opened downward, the urine can be discharged directly into the storage container 20 from the portion corresponding to the outflow pipe. For this reason, the inside of the part corresponded to an outflow pipe can be prevented from becoming full by the urine which flows in from the upward flow path U, and can prevent the occurrence of a siphon action.

The present invention is not limited to the first to seventh embodiments described by the above description and drawings, and the following examples are also included in the technical scope of the present invention.

(1) In Examples 1 to 7, although the external shape of the urine drain trap was cylindrical, it may not be cylindrical. In this case, the partition and the folded portion are not cylindrical, but may be a cylindrical shape along the side wall of the main body.

(2) In Examples 1-7, although the upper end of the return part is formed lower than the lower surface of a seal layer, you may be located in a seal layer.

(3) In Examples 1 and 2, the outflow pipe is formed in a semi-cylindrical shape, and the arc-shaped outer surface is disposed in contact with the inner surface of the partition wall portion, but the outflow pipe may not be a semi-cylindrical shape.

(4) In Example 2, the main body is directly attached to the lower end of the foot of the urinal, but the main body may be formed integrally with the urinal main body.

(5) In Examples 1, 2, 5, and 6, although the outer side surface of the outflow pipe is arrange | positioned in contact with the inner side surface of a partition, although the outflow pipe does not contact the inner side of a partition, it is shifted to one side in a partition part by planar view. It is good to be placed in a lost position.
