Summary of the invention
Invent problem to be solved
But in the disclosed urinal drain trap of Figure 12 of patent documentation 1, because the runner in first area is shorter, therefore urine flows into the 3rd region strongly from the first area force and velocity of a current.Therefore, sealing fluid is easily transported in the 3rd region together with the urine flowing into the 3rd region.And, due in the 3rd region, return portion is the inclined plane that downstream gently declines, and therefore runner variation is in vertical direction less, thus be transported to sealing fluid in the 3rd region easily along with flowing of urine downstream the second area of side be transferred.Because the proportion that is transported to the sealing fluid in second area is lighter than urine, therefore sealing fluid rises in second area by its buoyancy.In this way, the sealing fluid being transported in second area cannot return to first area, thereby flows out from flow export.Therefore, by the use because of long-term, sealing fluid flows out from flow export gradually, thereby sealing fluid reduces, and then sealant attenuation.In the time of sealant attenuation, the foul smell of the urine storing likely distributes from inflow entrance.
In addition, in Fig. 1 of patent documentation 1 in disclosed urinal drain trap, effuser is configured in and wall part concentric position place, and the rising runner of urine in second area is formed, and between the lateral surface of effuser and the medial surface of wall part, has fixing interval.Owing to being detained and having urine in this part, therefore easily adhere to gelatinous urinary calculi.In the time that the interval between the lateral surface of effuser and the medial surface of wall part is narrower, because the gelatinous urinary calculi being attached on the lateral surface of effuser and the medial surface of wall part is piled up, thus the possibility that exists rising runner to stop up in early days.
The present invention completes in view of above-mentioned existing situation, and its problem to be solved is, a kind of urinal drain trap is provided, and this urinal drain trap can prevent distributing of foul smell for a long time, or carries out well the discharge of urine for a long time.
For solving the method for problem
Urinal drain trap of the present invention has: cap, and its embedding is arranged in the opening on the bottom of alms bowl face of urinal, and has the inflow entrance flowing into for the urine flowing down along described alms bowl face, main part, it has: the side wall portion that forms in the mode of extending downwards from the peripheral portion of described cap, with the continuous mode in the lower end of this side wall portion and the bottom forming and the flow export that supplies the urine overflow being stored, the wall part of cavity shape, it is arranged at the inner side of the peripheral portion of described cap, and between lower end and the bottom of described main part, interval opening are set, in described main part, be divided into by described wall part, be formed at the first area and the second area that is formed at inner side in the outside of this wall part, described first area and described second area are communicated with by the 3rd region, described the 3rd region is formed on the below of lower end and the top of described bottom of described wall part, in described first area, be injected with sealing fluid, described sealing fluid is water-insoluble, and proportion is lighter than urine, thereby be formed with sealant above stored urine, described urinal drain trap is characterised in that, in the lower edge portion of described wall part, be formed with, towards described first area and the linking part of horizontal expansion, and in the tip edge portion of this linking part, be formed with the return portion of extending upward, described inflow entrance is run through to be arranged at, the position that between described wall part and described return portion, urine flows into from top, described flow export is in described second area, and the upper opening of the upper end of described return portion.
In this urinal drain trap, the urine flowing into from inflow entrance is broken through sealant and is flowed between wall part and return portion from top.Because the lower end of wall part and the lower end of return portion are bonded by linking part, therefore, in the region being surrounded by wall part, linking part and return portion (following, to be called watershed), flowing of urine transfers rising to from declining, thereby produces convection current.Due to the inflow of urine, sealant is stirred, thereby is inhaled into the majority in the urine of below of sealant, is rolled in this convection current.Therefore, sealing fluid rests in watershed.When the inflow of urine stops, thereby when absence of convection, the sealing fluid resting in watershed will float by its buoyancy, thus with the sealant interflow of top.
In addition, from basin, cross the upper end of return portion and towards the force and velocity of a current of urine the 3rd region, in decline runner, decay compared with the force and velocity of a current of the urine when flowing into watershed.Therefore, cross the sealing fluid of the upper end of return portion from watershed along with flowing of urine, be transported to the centre position place of decline runner and stop, be therefore difficult for being transported in the 3rd region.In the time of mobile the stopping of urine, the sealing fluid resting in this decline runner will float by its buoyancy, thus with the sealant interflow of top.
In this way, because sealing fluid is difficult for because flowing of urine is transported in the 3rd region, thereby can suppress sealing fluid from being arranged in contrast the outflow of flow export in downstream.Therefore,, even if use for a long time, also can suppress the minimizing of sealing fluid, thereby sealant is difficult for attenuation.
Therefore, urinal drain trap of the present invention can prevent distributing of foul smell chronically.
Described inflow entrance can run through setting along described wall part.In this kind of situation, the urine flowing into from inflow entrance is dispersed, thereby the force and velocity of a current of the urine flowing into main part is weakened.Therefore, can suppress the inflow of urine to the stirring of sealant, thereby sealing fluid is difficult for being inhaled into the below of sealant.Thus, can further suppress the outflow of sealing fluid.In addition, because the urine flowing into from inflow entrance flows down along the surface of wall part, thereby can suppress the stirring to sealant.Also can suppress thus the outflow of sealing fluid.Therefore, sealant is difficult for attenuation, thereby can prevent distributing of foul smell.
Described return portion can be set to, and has fixing interval between described wall part.In this case, owing to being formed with fixing interval between return portion and wall part, thereby can in whole watershed, produce convection current.Therefore, owing to can making along with the flowing of urine, and the sealing fluid of crossing the upper end of return portion from watershed reduces, thereby can suppress the outflow of sealing fluid.In addition, even be attached with gelatinous urinary calculi on the medial surface of watershed time, gelatinous urinary calculi is also difficult for piling up unevenly in watershed.Therefore, can suppress, because gelatinous urinary calculi is deposited in specific position in early days, not produce convection current in this position, thus the phenomenon that causes sealing fluid to flow out.Therefore, sealant is difficult for attenuation, thereby can prevent distributing of foul smell.
Described return portion can extend to, more than the central height between tip edge portion and the upper surface of described sealant of described linking part.In this case, owing to can form effectively convection current in watershed, thereby the sealing fluid that is inhaled into the below of sealant is rolled in the convection current in watershed, thereby rests in watershed.In addition, because the upper end of return portion is configured in the higher position in first area, thereby can make the sealing fluid of crossing the upper end of return portion from watershed reduce.Therefore, can suppress the outflow of sealing fluid.Therefore, sealant is difficult for attenuation, thereby can prevent distributing of foul smell.
The upper end of described return portion can be lower than the soffit of described sealant.In this case, can suppress urine effluent goes out downstream crossing the upper end of return portion from watershed time, from the situation of sealant suction seal liquid.Therefore, can suppress the outflow of sealing fluid.Therefore, sealant is difficult for attenuation, thereby can prevent distributing of foul smell.
Described return portion can be arranged at the central position between described wall part and described side wall portion.In this case, due to the interval between wall part and return portion, identical with the interval between return portion and side wall portion, therefore gelatinous urinary calculi can not be deposited in specific position in early days, thereby can suppress the obstruction causing due to the accumulation of gelatinous urinary calculi.

Accommodating container 20 is embedded with seal 22 the lateral surface of latch for printed circuit 21 is upper outside, and accommodating container 20 is inserted in the opening 2A the bottom of the alms bowl face 2 that is formed at urinal 1 from top.The flange part 21B of latch for printed circuit 21 is limited on the upper surface of edge part of opening 2A.In the threaded portion on top of lateral surface that is formed on accommodating container 20, be screwed with embedding from the below of accommodating container 20, and upper surface is limited to the link 23 of the annular shape on the soffit of edge part of opening 2A.In this way, carry out the edge part of grasp opening 2A by the flange part 21B by latch for printed circuit 21 and link 23, thereby accommodating container 20 is installed in opening 2A.Accommodating container 20 has the connecting piece 24 of extension from lower vertex angle part.Accommodating container 20 is connected to the gutter 4 being drawn out on wall W via connecting piece 24.
The urinal drain trap 10 that is formed filter box-like formula has cap 11, main part 12 and wall part 13.The profile of cap 11 is round-shaped.In opening on the bottom of the alms bowl face 2 that cap 11 embeds the opening that forms by the latch for printed circuit 21 of accommodating container 20, be arranged at urinal 1.The annular recessed portion forming on the peripheral end face of cap 11 has been embedded in seal P.The lateral surface of the medial surface of the opening therefore, forming by latch for printed circuit 21 and cap 11 is joined together in the mode of watertightness.Therefore the urine, flowing down along the alms bowl face 2 of urinal 1 flows on the upper surface of cap 11.On cap 11, run through the inflow entrance 11A that is provided with the urine inflow flowing down for the alms bowl face 2 along urinal 1.
Main part 12 has side wall portion 12A, bottom 12B and flow export 12C.Side wall portion 12A is drum, and extends downwards from the peripheral portion of cap 11.The upper end of the peripheral portion of cap 11 and side wall portion 12A is bonded together in gapless mode.Pars intermedia place at the lateral surface of side wall portion 12A is formed with multiple engagement protuberance 12F.As described above, be limited in the engagement recess 20A on the medial surface that is formed on accommodating container 20 by engagement protuberance 12F, thereby the urinal drain trap 10 of filter box-like formula is installed in accommodating container 20 in removable mode.Bottom 12B is to form with the continuous mode in the lower end of side wall portion 12A.
Wall part 13 is drum, is arranged at the inner side of the peripheral end of cap 11, and extends downwards from the upper end of sealing, and for being provided with the empty shape of interval opening between lower end and the bottom 12B of main part 12.Wall part 13 and cap 11 be arranged on coaxial on.On cap 11, dispose along the lateral surface of wall part 13 and be divided into multiple inflow entrance 11A in the mode of ring-type.
In main part 12, be divided into by wall part 13, be formed at the first area 31 and the second area 32 that is formed at inner side in the outside of wall part 13.First area 31 and second area 32 are communicated with by the 3rd region 33, and described the 3rd region 33 is formed on the below of lower end of wall part 13 and the top of the bottom 12B of main part 12.In first area 31, be injected with sealing fluid, described sealing fluid is non-solubization, and proportion is lighter than urine, thereby forms sealant S above stored urine.
Wall part 13, at the peripheral portion place of lower end, is formed with towards first area 31 and the linking part 14 of the annular shape of horizontal expansion.Linking part 14 is formed with the return portion 15 of the drum extending upward in tip edge portion.Between return portion 15 and wall part 13, there is fixing interval.In addition, return portion 15 is arranged at the central position between wall part 13 and side wall portion 12A., on return portion 15, wall part 13 and main part 12 are configured in coaxially.In addition, the upper end of return portion 15 is formed, in first area 31, extend to upward as upper/lower positions, that is, and lower than the position that is formed on soffit top, sealant S that stores the urine in main part 12.In addition, return portion 15 extends to, more than the central height between the tip edge portion of linking part 14 and the upper surface of sealant S.
Flow export 12C is formed on the upper end of effuser 12D, and described effuser 12D bottom 12B from main part 12 in second area 32 erects.In addition, flow export 12C is at the upper opening of the upper end of return portion 15.Effuser 12D is formed semicircular cylinder shape, and is configured to, and the medial surface of circular-arc lateral surface and wall part 13 is joined.That is, effuser 12D is configured in, and is offset to the position of the side in wall part 13 in the time overlooking observation.
The bottom of effuser 12D is along the bottom 12B of main part 12 and to the direction bending of side wall portion 12A.On the bottom 12B of the downstream end of effuser 12D, run through and be provided with outlet opening 12E.The urinal drain trap 10 of filter box-like formula, so that this outlet opening 12E is disposed at towards the mode of the position of the upstream portion of the connecting piece 24 of accommodating container 20, is installed in accommodating container 20.
Size X in the vertical direction in the 3rd region 33 is formed, and is greater than at the decline runner D of interior the formed urine in first area 31 and in the central authorities rising runner U of interior the formed urine of second area 32, vertical and analyses and observe lateral dimension Y, the Z while observing.
In the urinal drain trap 10 with this structure, the urine flowing into from inflow entrance 11A, breaks through sealant S and flow between wall part 13 and return portion 15 from top.So in (following, to be called watershed T), flowing of urine transfers rising to from declining, thereby produces convection current in the region being surrounded by wall part 13, linking part 14 and return portion 15.Due to the inflow of urine, sealant S is stirred, thereby is inhaled into the majority in the sealing fluid of below of sealant S, is involved in this convection current.Therefore sealing fluid rests in watershed T.When the inflow of urine stops, thereby when absence of convection, the sealing fluid resting in watershed T floats by its buoyancy, thus with the sealant S interflow of top.
In addition, cross the upper end of return portion 15 force and velocity of a current towards urine the 3rd region 33, decline runner D from watershed T, decay compared with the force and velocity of a current of the urine when flowing into watershed T.Therefore, along with flowing of urine, and crossed the sealing fluid of the upper end of return portion 15 from watershed T, be transported to the centre position place of decline runner D and stop, thereby be difficult for being transported in the 3rd region 33.In the time of mobile the stopping of urine, the sealing fluid being stranded in this decline runner D floats by its buoyancy, thus with the sealant S interflow of top.
In this way, because sealing fluid is difficult for because flowing of urine is transported in the 3rd region 33, therefore can suppress sealing fluid from being configured in the outflow of flow export C in downstream in the 3rd region.Therefore,, even if use for a long time, also can suppress the minimizing of sealing fluid, thereby sealant S is difficult for attenuation.
Therefore, the urinal drain trap 10 of embodiment 1 can prevent distributing of foul smell chronically.
In addition, be set to because inflow entrance 11A runs through, be divided into multiple annular shape along the lateral surface of wall part 13, the urine therefore flowing into from inflow entrance 11A is dispersed, thereby the force and velocity of a current that flows into the urine in main part 12 is weakened.Therefore, the stirring of the inflow that has suppressed urine to sealant S, thus sealing fluid is difficult for being inhaled into the below of sealant S.Thus, can further suppress the outflow of sealing fluid.And, because the urine flowing into from inflow entrance 11A flows down along the lateral surface of wall part 13, therefore suppress the stirring of sealant S.Also can suppress thus the outflow of sealing fluid.Therefore, sealant S is difficult for attenuation, thereby can prevent distributing of foul smell.
In addition, because return portion 15 is configured to, and there is fixing interval between wall part 13, thereby can in whole watershed T, produce convection current.Therefore, can make the sealing fluid of the upper end of crossing return portion 15 along with flowing of urine from watershed T reduce.Therefore, can suppress the outflow of sealing fluid.In addition, even if be attached with gelatinous urinary calculi on the inner surface of watershed T, gelatinous urinary calculi also can not piled up unevenly in watershed T.Therefore, can suppress due to gelatinous urinary calculi in early days specific location pile up, thereby and do not occur in this position convection current cause sealing fluid flow out phenomenon.Therefore, sealant S is difficult for attenuation, thereby can prevent distributing of foul smell.
In addition, due to more than return portion 15 extends to the central height between the tip edge portion of linking part 14 and the upper surface of sealant S, therefore can in watershed T, form effectively convection current, and the sealing fluid of the below that is inhaled into sealant S is rolled in the convection current in watershed T, make thus sealing fluid rest in watershed.In addition, because the upper end of return portion 15 is configured in the higher position in first area 31, thereby can make the sealing fluid of crossing the upper end of return portion 15 from watershed T reduce.Therefore, can suppress the outflow of sealing fluid.Therefore, sealant S is difficult for attenuation, thereby can prevent distributing of foul smell.
In addition, because the upper end of return portion 15 is formed, lower than the soffit of sealant S, therefore can suppress urine effluent goes out downstream crossing the upper end of return portion 15 from watershed T time, from the situation of sealant S suction seal liquid.Therefore, can suppress the outflow of sealing fluid.Therefore, sealant S is difficult for attenuation, thereby can prevent distributing of foul smell.
In addition, because return portion 15 is arranged at the central position between wall part 13 and side wall portion 12A, therefore gelatinous urinary calculi can not be deposited in early days, the specific position of the decline runner D forming in the watershed T forming between wall part 13 and return portion 15 and between return portion 15 and side wall portion 12A, thus the obstruction causing due to the accumulation of gelatinous urinary calculi can be suppressed.
In addition, size X in the vertical direction in the 3rd region 33 is formed, be greater than the rising runner U of the decline runner D of interior the formed urine in first area 31 and the urine that forms in second area, vertical central authorities analyse and observe horizontal size Y, Z while observing.That is, in the 3rd region of easily piling up at gelatinous urinary calculi, the size in its vertical direction is formed greatlyr, thereby can make the 3rd region 33 be difficult for stopping up because of the accumulation of gelatinous urinary calculi.Therefore, can carry out well the discharge of urine.
In addition, because urinal drain trap 10 is formed filter box-like formula, therefore can, in the time of the obstruction that the minimizing of sealing fluid occurs or caused by the accumulation of urinary calculi etc., whole box be changed.Therefore, easy putting maintenance into practice.In addition, because this urinal drain trap can suppress the obstruction being caused by the accumulation of gelatinous urinary calculi, therefore can reduce the replacement frequency of box.
In addition, have in the urinal drain trap 10 of this structure, be formed drum by wall part 13, effuser 12D is formed semicircular cylinder shape, and the configuration of joining of the medial surface of circular-arc lateral surface and wall part 13, thereby effuser 12D is configured in and overlooks the position that is offset to the side in wall part 13 while observation.Therefore, the opposite side in the time overlooking observation in wall part 13, can expand the interval between effuser 12D lateral surface and the medial surface of wall part 13.Therefore,, even pile up and have gelatinous urinary calculi on the lateral surface of effuser 12D and the medial surface of wall part 13, also can make to be difficult for stopping up by surrounded the rising runner U forming by the medial surface of the lateral surface of effuser 12D and wall part 13.
Therefore, the urinal drain trap 10 of embodiment 1 can carry out the discharge of urine for a long time well.
In addition, can be overlooking the opposite side in wall part 13 while observing, expand interval between lateral surface and the medial surface of wall part 13 of effuser 12D simultaneously, the cross section of fluid channel area of effuser 12D is increased.Therefore, can guarantee fully the outflow flow of the urine flowing out from effuser 12D, thereby can carry out well the discharge of urine.

Therefore, the urinal drain trap 210 of embodiment 3 also can prevent distributing of foul smell chronically.
< embodiment 4>
As shown in Figure 7, the urinal drain trap 310 of embodiment 4 has cap 311, main part 312 and wall part 313.Main part 312 has side wall portion 312A, bottom 312B and flow export 312C.Side wall portion 312A is drum, is formed with banded protuberance 312D at the pars intermedia place of lateral surface.Main part 312 is directly installed on the bottom of alms bowl face 2 of urinal 1 by latch for printed circuit 321.Latch for printed circuit 321 has: the cylindrical portion 321A of drum, and it surrounds the top of main part 312; The flange part 321B of annular shape, the upper end of itself and cylindrical portion 321A is continuous, and expansion laterally; Annular recessed portion 321C, the lower end of itself and cylindrical portion 321A is continuous, and engages with protuberance 312D.In addition, latch for printed circuit 321 has the fastener 321D of half-circle-arc shape, between this fastener 321D and flange part 321B, the edge part of opening 2A of lower end of the alms bowl face 2 that is formed on urinal 1 is clamped.Fastener 321D can resilient movement, thereby and carry out to the inside resilient movement from top by opening 2A, and moving to outside by rear.In this way, fastener 321D is limited to the soffit of the edge part of opening 2A.Outside between flange part 321B and fastener 321D, be embedded with seal 22.
On side wall portion 312A, be provided with the flow export 312C of the upper opening of the upper end of the return portion 315 being described below.On main part 312, be provided with the connecting piece 324 of horizontal expansion from flow export 312C.Urinal drain trap 310 is by the connecting piece 324 of horizontal expansion from top, and is connected with the distribution pipe 4 being led on wall W.
The profile of cap 311 is round-shaped.Cap 311 is inserted into, the opening on the bottom of the opening forming by the latch for printed circuit 321 main part 312 being installed on the bottom of alms bowl face 2 of urinal 1, the alms bowl face 2 that is arranged on urinal 1.In annular recessed portion on the peripheral end face that is formed on cap 311, embed and have seal P.The lateral surface of the medial surface of the opening therefore, forming by latch for printed circuit 321 and cap 311 is joined together in the mode of watertightness.Therefore, along the alms bowl face 2 of urinal 1 and the urine flowing down flow on the upper surface of cap 311.On cap 311, be provided with the inflow entrance 311A of the urine inflow flowing down for the alms bowl face 2 along urinal 1.
Wall part 313 is drum, is arranged at the inner side of the peripheral end of cap 311, and is provided with interval opening between lower end and the bottom 312B of main part 312.Wall part 313 and cap 311 be arranged at coaxial on.On cap 311, dispose with annular shape, along the medial surface of wall part 311 and be divided into multiple inflow entrance 311A.
In main part 312, is divided into by wall part 313, be formed at wall part 313 outside first area 331 and be formed at the second area 332 of inner side.First area 331 and second area 332 are communicated with by the 3rd region 333, and described the 3rd region 333 is formed on the below of lower end of wall part 313 and the top of the bottom 312B of main part 312.In second area 332, be injected with sealing fluid, described is non-solubization, and proportion is lighter than urine, thereby forms sealant S above stored urine.
In the inner edge portion of the lower end of wall part 313, be formed with, towards the linking part 314 of the annular shape of second area 332 horizontal expansions.In the tip edge portion of linking part 314, be formed with, extend to upward the return portion cylindraceous 315 till the height of pars intermedia of wall part 313.Between return portion 315 and wall part 313, there is fixing interval., on return portion 315 and wall part 313 are configured in coaxially.In addition, the upper end of return portion 315 is formed, in second area 332, extend to upward as upper/lower positions, that is, and lower than the position that is formed on soffit top, sealant S that stores the urine in main part 312.
In the urinal drain trap 310 with this kind of structure, the urine flowing into from inflow entrance 311A is broken through sealant S and flow between wall part 313 and return portion 315 from top.So in the region being surrounded by wall part 313, linking part 314 and return portion 315, in watershed T, flowing of urine transfers rising to from declining, thereby produces convection current.Due to the inflow of urine, sealant S is stirred, and is inhaled into the majority in the sealing fluid of below of sealant S, is involved in to this convection current.Therefore sealing fluid rests in watershed T.When the inflow of urine stops, thereby when absence of convection, the sealing fluid resting in watershed T will float by its buoyancy, thus with the sealant S interflow of top.
In addition, cross the upper end of return portion 315 force and velocity of a current towards urine the 3rd region 333, decline runner D from watershed T, decay compared with the force and velocity of a current of the urine when flowing into watershed T.Therefore, along with flowing of urine, and crossed the sealing fluid of the upper end of return portion 315 from watershed T, be transported to the centre position place of decline runner D and stop, thereby be difficult for being transported in the 3rd region 333.In the time of mobile the stopping of urine, in this decline runner D, the sealing fluid of convection current will float by its buoyancy, thus with the sealant S interflow of top.
In this way, because sealing fluid is difficult for because flowing of urine is transported in the 3rd region 333, therefore can suppress sealing fluid from being arranged at the outflow of flow export 312C in downstream in the 3rd region 333.Therefore,, even if use for a long time, also can suppress the minimizing of sealing fluid, thereby sealant S is difficult for attenuation.
Therefore, the urinal drain trap 310 of embodiment 4 also can prevent distributing of foul smell chronically.
In addition, be set to because inflow entrance 311A runs through, be divided into multiple annular shape along the lateral surface of wall part 313, the urine therefore flowing into from inflow entrance 311A is dispersed, thereby the force and velocity of a current that flows into the urine of main part 312 is weakened.Therefore, the stirring of the inflow that has suppressed urine to sealant S, thus sealing fluid is difficult for being inhaled into the below of sealant S.Thus, can further suppress the outflow of sealing fluid.In addition, due to the urine flowing into from inflow entrance 11A, flow down along the medial surface of wall part 313, therefore suppressed the stirring to sealant S.Thus, can also can suppress the outflow of sealing fluid.Therefore, sealant S is difficult for attenuation, thereby can prevent distributing of foul smell.
In addition, because return portion 315 is set to have fixing interval between wall part 313, therefore can in whole watershed T, produce convection current.Therefore, can make the sealing fluid of the upper end of crossing return portion 315 along with flowing of urine from watershed T reduce.Therefore can suppress the outflow of sealing fluid.In addition, even if be attached with gelatinous urinary calculi on the inner surface of watershed T, gelatinous urinary calculi also can not piled up unevenly in watershed T.Therefore, can suppress because gelatinous urinary calculi is deposited in specific position in early days, convection current can not occur in this position, thus the phenomenon that causes sealing fluid to flow out.Therefore, sealant S is difficult for attenuation, thereby can prevent distributing of foul smell.
In addition, because the upper end of return portion 315 is formed, lower than the soffit of sealant S, therefore can suppress urine in the time crossing the upper end of return portion 315 from watershed T and effluent goes out downstream, from the phenomenon of sealant S suction seal liquid.Therefore, can suppress the outflow of sealing fluid.Therefore, sealant S is difficult for attenuation, thereby can prevent distributing of foul smell.
In addition, owing to being formed with the decline runner D that flowing path section area is larger in the inside of return portion 315, therefore gelatinous urinary calculi can not piled up in early days, thereby can suppress the obstruction causing due to the accumulation of gelatinous urinary calculi.
