Further, a rod-shaped knob 26 is stretched over the inlet 25 so as to pass through the center of the inlet 25. Furthermore, a female screw 8 a into which the male screw 24 a of the deodorizing cylinder 22 is screwed is formed between the water receiving portion 10 and the outer peripheral flow path portion 12 in the trap body 8.

また、封水椀部１１及び防臭筒２２をトラップ本体８に取り付ける際には、先ず封水椀部１１をトラップ本体８の上面開口から挿入してトラップ本体８の底面に形成された取り付け部１８に取り付ける。そして、防臭筒２２をトラップ本体８に上方から挿入し、摘み片２６を摘んで防臭筒２２を回転させることで、フランジ部２４の外周縁端面に形成された雄ネジ２４ａがトラップ本体８に形成された雌ネジ８ａに螺合して取り付けられる。これにより、トラップ本体８の内部がフランジ部２４により上下に区画され、流入口２５のみを介してトラップ本体８の上下部、すなわち上方の水受椀部１０と下方の封水椀部１１及び外周流路部１２とが連通されることになる。 In addition, when attaching the sealed water bottle part 11 and the deodorizing cylinder 22 to the trap body 8, first, the sealed water bottle part 11 is inserted from the upper surface opening of the trap body 8 and the attachment part 18 formed on the bottom surface of the trap body 8. Attach to. Then, the deodorizing cylinder 22 is inserted into the trap body 8 from above, the knob 26 is picked and the deodorizing cylinder 22 is rotated, so that the male screw 24 a formed on the outer peripheral edge of the flange portion 24 is formed in the trap body 8. The female screw 8a is attached by screwing. As a result, the inside of the trap body 8 is vertically divided by the flange portion 24, and the upper and lower portions of the trap body 8, that is, the upper water receiving portion 10, the lower sealing tub portion 11, and the outer periphery only through the inflow port 25. The flow path part 12 is communicated.

尚、図２に示すように、防臭筒２２がトラップ本体８の取り付け部１８に取り付けられると、封水椀部１１の突起部２７が防臭筒２２のフランジ部２４の下面に当接され、封水椀部１１の底面が取り付け部１８の上面に当接した状態で固定される。このとき、封水椀部１１の上端縁とフランジ部２４の下面との間には、突起部２７の高さ分の間隙が形成されるようになっているとともに、防臭筒２２を回転させて雄ネジ２４ａを雌ネジ８ａに螺合すればするほど防臭筒２２が下方に向けて押圧され、封水椀部１１の下面が取り付け部１８の上面に強く圧接されるため、取り付け部１８の上面と封水椀部１１の下面とがより強く密接される。 As shown in FIG. 2, when the deodorizing cylinder 22 is attached to the attaching portion 18 of the trap body 8, the protrusion 27 of the sealing tub portion 11 is brought into contact with the lower surface of the flange portion 24 of the deodorizing cylinder 22 and sealed. The water tank portion 11 is fixed in a state where the bottom surface of the water tank portion 11 is in contact with the upper surface of the attachment portion 18. At this time, a gap corresponding to the height of the protrusion 27 is formed between the upper end edge of the water seal portion 11 and the lower surface of the flange portion 24, and the deodorizing cylinder 22 is rotated. The more the male screw 24a is screwed into the female screw 8a, the more the deodorizing cylinder 22 is pressed downward, and the lower surface of the water seal portion 11 is strongly pressed against the upper surface of the mounting portion 18. And the lower surface of the sealed water bottle part 11 are more closely brought into close contact with each other.

このように構成された排水トラップ３にあっては、図２に示すように、シンク２から流れてきた排水が封水椀部１１に溜まるようになっているとともに、この封水椀部１１内に上方から防臭筒２２の筒体２３が挿入され、筒体２３の下端と封水椀部１１の底面との間及び封水椀部１１の内周と筒体２３の外周との間に隙間、すなわち流路が形成されるように配置した状態でフランジ部２４の雄ネジ２４ａを雌ネジ８ａに螺合して封止することで、流入口２５と流出口１９とが封水椀部１１を介してのみ連通することになるが、この封水椀部１１内に所定レベル（例えば水面α）まで水が溜まることにより、筒体２３の下端と封水椀部１１の底面との間及び封水椀部１１の内周と筒体２３の外周との間に形成された隙間が水により塞がる、すなわち封水椀部１１と防臭筒２２とにより封水（封水椀部１１内に溜まる排水）が形成されることにより、下水側、つまり流出口１９側からの臭気や害虫等が屋内側に進入してきても、この封水椀部１１を通過することができないようになっている。尚、排水の流速を高めるため、筒体２３の下端と封水椀部１１の底面との間及び封水椀部１１の内周と筒体２３の外周との間に形成された隙間は５〜９ｍｍであることが好ましい。 In the drain trap 3 configured in this way, as shown in FIG. 2, the drainage flowing from the sink 2 is accumulated in the sealed water bottle part 11, and the inside of the sealed water bottle part 11 From above, the cylinder body 23 of the deodorizing cylinder 22 is inserted, and a gap is formed between the lower end of the cylinder body 23 and the bottom surface of the sealed water bottle part 11 and between the inner periphery of the sealed water bottle part 11 and the outer periphery of the cylinder body 23. That is, in a state where the flow path is formed, the male screw 24a of the flange portion 24 is screwed into the female screw 8a and sealed, whereby the inflow port 25 and the outflow port 19 are connected to the sealed water bottle portion 11. However, when water accumulates up to a predetermined level (for example, the water surface α) in the sealed water bottle portion 11, between the lower end of the cylindrical body 23 and the bottom surface of the sealed water bottle portion 11, and The gap formed between the inner periphery of the sealing flange 11 and the outer periphery of the cylinder 23 is blocked by water. By forming a sealed water (drainage accumulated in the sealed water bottle part 11) by the sealed water bottle part 11 and the deodorizing cylinder 22, odors, pests and the like from the sewage side, that is, the outlet 19 side, are placed indoors. Even if it enters, it cannot pass through this sealed water bottle part 11. In order to increase the flow rate of the drainage, the gap formed between the lower end of the cylindrical body 23 and the bottom surface of the sealed water bottle part 11 and between the inner periphery of the sealed water bottle part 11 and the outer periphery of the cylindrical body 23 is 5 It is preferably ˜9 mm.

尚、防臭筒２２の摘み片２６の中央部には、本実施例における接触部材としての上方に突出する凸部２６ａと下方に突出する凸部２６ｂが形成されている。上方側に突出する凸部２６ａは、網かご１４の最下面に当接するようになっているとともに、下方側に突出する凸部２６ｂは、封水椀部１１に溜められた封水の水面αに接触するように形成されている。 In addition, the convex part 26a which protrudes upwards as the contact member in a present Example, and the convex part 26b which protrudes below are formed in the center part of the pick piece 26 of the deodorizing cylinder 22. As shown in FIG. The convex portion 26a that protrudes upward is in contact with the lowermost surface of the net cage 14, and the convex portion 26b that protrudes downward is the water surface α of the sealed water stored in the sealing lid 11. It is formed so that it may contact.

このように防臭筒２２に設けられた摘み片２６に、網かご１４の下面と封水の水面αの両方に接触できる凸部２６ａ，２６ｂが設けられることで、水が有する表面張力によって、網かご１４の網目に停滞する水が凸部２６ａ，２６ｂを介して封水椀部１１に溜められた封水に流れ落ちるようになり、網かご１４の乾燥を早めることができ、網かご１４におけるカビ等の発生を防ぐことができる。 In this manner, the knob 26 provided on the deodorizing cylinder 22 is provided with the convex portions 26a and 26b that can come into contact with both the lower surface of the mesh basket 14 and the water surface α of the sealed water, so that the net tension by the surface tension of the water Water stagnating in the mesh of the basket 14 flows down to the sealed water stored in the sealed water bottle portion 11 through the convex portions 26a and 26b, so that the drying of the mesh basket 14 can be accelerated, and mold in the mesh basket 14 Etc. can be prevented.

次に、排水がシンク２から排水トラップ３内に連続的に流入したときの排水の流れについて説明する。図２に示すように、シンク２から蓋体１５の板部材１６上に流れ込んだ排水は、板部材１６の上面から皿部１７に流れ込み、皿部１７から流入孔（図示略）を介して水受椀部１０に流入される。 Next, the flow of drainage when drainage continuously flows from the sink 2 into the drain trap 3 will be described. As shown in FIG. 2, the waste water that has flowed from the sink 2 onto the plate member 16 of the lid body 15 flows into the plate portion 17 from the upper surface of the plate member 16, and from the plate portion 17 through an inflow hole (not shown). It flows into the receiving part 10.

そして、水受椀部１０内に流れ落ちて防臭筒２２のフランジ部２４上を流れる排水は、環状のフランジ部２４の中央部に形成された流入口２５から筒体２３内を流下して下方の封水椀部１１に流れ落ちる。図２に示すように、封水椀部１１に所定量の排水が流入すると、封水椀部１１の上端縁とフランジ部２４の下面との間に形成された間隙から封水椀部１１内の排水が溢れ出し、外周流路部１２に流れ落ちるようになっている。 And the drainage which flows down in the water receiving part 10 and flows on the flange part 24 of the deodorizing cylinder 22 flows down in the cylinder 23 from the inflow port 25 formed in the center part of the annular flange part 24, and below. It flows down to the sealed water trough 11. As shown in FIG. 2, when a predetermined amount of drainage flows into the sealed water bottle part 11, the inside of the sealed water bottle part 11 is formed from a gap formed between the upper end edge of the sealed water bottle part 11 and the lower surface of the flange part 24. The waste water overflows and flows down to the outer peripheral flow path portion 12.

また、封水椀部１１の底面に、中央部が上方に突出された山型部１３が形成されていることで、封水椀部１１の底面の中央にゴミが溜まりにくくなるばかりか、封水椀部１１の底面外周部寄り、すなわち封水椀部１１の内周面と筒体２３の外周面との間に形成される流路に向けてゴミが流動しやすくなるため、封水椀部１１の底面の外周に溜まったゴミは、排水の水流により浮上し、封水椀部１１から排水とともに外周流路部１２に溢れ出やすくなる。外周流路部１２に流入した排水は、流出口１９から排水管４に流出する。 In addition, by forming a chevron 13 with the central portion protruding upward on the bottom surface of the sealing water bottle portion 11, not only does it become difficult for dust to collect at the center of the bottom surface of the sealing water bottle portion 11, but also the sealing. Since dust tends to flow toward the flow path formed near the outer peripheral surface of the bottom surface of the water tank portion 11, that is, between the inner peripheral surface of the water seal portion 11 and the outer peripheral surface of the cylindrical body 23. The dust collected on the outer periphery of the bottom surface of the portion 11 floats due to the water flow of the drainage, and tends to overflow from the sealed water trough 11 to the outer peripheral flow path portion 12 together with the drainage. The waste water that has flowed into the outer peripheral flow path portion 12 flows out from the outlet 19 to the drain pipe 4.

尚、封水椀部１１の突起部２７がフランジ部２４の下面に当接されていることで、外周流路部１２に排水が流れ込んだときに、該外周流路部１２の排水により封水椀部１１が浮上することを防ぐことができる。そのため封水椀部１１の底面と取り付け部１８の上面とが密着された状態を維持でき、排水に含まれるゴミが封水椀部１１の底面と取り付け部１８の上面との間に詰まることがないばかりか、封水椀部１１が浮上することによって、封水椀部１１の上端縁とフランジ部２４の下面との間の間隙（流路）が狭まることがなく、封水椀部１１から外周流路部１２に溢れ出る排水を速やかに流すことができる。 In addition, when drainage flows into the outer periphery flow path part 12 by the protrusion part 27 of the sealing water bottle part 11 being contact | abutted to the lower surface of the flange part 24, water is sealed by drainage of this outer periphery flow path part 12. It is possible to prevent the collar portion 11 from rising. Therefore, it is possible to maintain a state in which the bottom surface of the sealed water bottle portion 11 and the top surface of the attachment portion 18 are in close contact with each other, and dust contained in the drainage is clogged between the bottom surface of the sealed water well portion 11 and the top surface of the attachment portion 18. In addition, since the sealed water ridge part 11 rises, the gap (flow path) between the upper end edge of the sealed water jar part 11 and the lower surface of the flange part 24 is not narrowed. The waste water overflowing to the outer peripheral flow path portion 12 can be quickly flowed.

尚、防臭筒２２の摘み片２６の中央部に形成された上方側に突出する凸部２６ａは、網かご１４の最下面に当接できるようになっているとともに、下方側に突出する凸部２６ｂは、封水椀部１１に溜められた封水の水面αに接触できるように形成されている。 In addition, the convex part 26a which protrudes to the upper side formed in the center part of the pick piece 26 of the deodorizing cylinder 22 can contact | abut to the lowermost surface of the mesh basket 14, and is a convex part which protrudes below. 26 b is formed so as to be able to come into contact with the water surface α of the sealed water stored in the sealed water bottle part 11.

次に、排水管４の高圧洗浄を行うときの排水トラップ３について説明する。図５に示すように、先端に高圧洗浄用の噴射ノズル２８を設けたホース２９をシンク２側から排水管４に挿入するためには、トラップ本体８から蓋体１５と防臭筒２２と封水椀部１１とを上方に取り外す。すると、流出口１９をトラップ本体８の上面開口である開口部９側（シンク２側）に開放され、ホース２９を開口部９側から外周流路部１２に設けられた流出口１９に挿入することができるようになる。そして、噴射ノズル２８から洗浄水を高圧で噴出させて排水管４の高圧洗浄を行うことができる。 Next, the drain trap 3 when performing high pressure cleaning of the drain pipe 4 will be described. As shown in FIG. 5, in order to insert a hose 29 provided with a high-pressure washing spray nozzle 28 at the tip into the drain pipe 4 from the sink 2 side, the trap body 8, the deodorizing cylinder 22, and the sealed water Remove the flange 11 upward. Then, the outflow port 19 is opened to the opening 9 side (sink 2 side) that is the upper surface opening of the trap body 8, and the hose 29 is inserted into the outflow port 19 provided in the outer peripheral flow path unit 12 from the opening 9 side. Will be able to. Then, it is possible to perform high-pressure cleaning of the drain pipe 4 by ejecting cleaning water from the spray nozzle 28 at high pressure.

以上説明してきたように、本発明の実施例１における排水トラップ３にあっては、トラップ本体８とは別個に形成された封水椀部１１をトラップ本体８の底面に形成された取り付け部１８から上方に取り外して流出口１９を開口部９側に開放させることができるため、流出口１９より下水側の排水管４の洗浄を容易に行うことができるとともに、封水椀部１１が汚れた場合、封水椀部１１を排水トラップ本体８から取り出した状態で清掃を行うことができるため、排水トラップ本体８内に手を深く挿入した無理な姿勢で清掃することなく、封水椀部１１内部を楽な姿勢で清掃作業を行うことができる。 As described above, in the drainage trap 3 according to the first embodiment of the present invention, the sealing water trough 11 formed separately from the trap body 8 is attached to the attachment portion 18 formed on the bottom surface of the trap body 8. Since the outlet 19 can be opened upward to the opening 9 side, the drain pipe 4 on the sewage side from the outlet 19 can be easily washed, and the sealed water trough 11 has become dirty. In this case, since the sealing tub portion 11 can be cleaned with the drain trap body 8 taken out from the drain trap body 8, the sealing tub portion 11 can be cleaned without cleaning in an unreasonable posture with a hand deeply inserted into the drain trap body 8. The interior can be cleaned with a comfortable posture.

また、防臭筒２２をトラップ本体８から取り外すだけで、取り付け部１８内に嵌合されていた封水椀部１１を簡単に取り出すことができるとともに、防臭筒２２をトラップ本体８に対してねじ込みにより取り付けできることで、封水椀部１１の底面が取り付け部１８の上面に圧接された状態で取り付け部１８に取り付けられることになるため、封水椀部１１の底面と取り付け部１８の上面との間にゴミが入り込むことが効果的に防止される。 Further, by simply removing the deodorizing cylinder 22 from the trap body 8, it is possible to easily take out the water seal portion 11 fitted in the mounting portion 18 and to screw the deodorizing cylinder 22 into the trap body 8. By being able to be attached, the bottom surface of the sealed water trough portion 11 is attached to the attachment portion 18 in a state where the bottom surface of the sealed water trough portion 11 is in pressure contact with the top surface of the mounting portion 18. It is effectively prevented that trash enters the door.

次に、実施例２に係る排水トラップにつき、図６から図８を参照して説明する。尚、前記実施例１に示される構成部分と同一構成部分に付いては同一符号を付して重複する説明を省略する。図６は、実施例２における排水トラップを示す縦断側面図であり、図７は、実施例２における防臭筒を示す斜視図であり、図８は、実施例２における封水椀部を示す斜視図である。 Next, a drain trap according to the second embodiment will be described with reference to FIGS. Note that the same components as those shown in the first embodiment are denoted by the same reference numerals and redundant description is omitted. 6 is a longitudinal side view showing a drain trap in the second embodiment, FIG. 7 is a perspective view showing a deodorizing cylinder in the second embodiment, and FIG. 8 is a perspective view showing a sealed water trough in the second embodiment. FIG.

図６に示すように、トラップ本体８の底面に形成された取り付け部１８には、上方から流れてくる排水を溜める封水椀部１１’が着脱自在に取り付けられる。図８に示すように、封水椀部１１’は上方が開放される有底円筒形状のお椀型を成しており、封水椀部１１’の側面には、複数の溢出口３０が形成されている。封水椀部１１’に溜められた封水は、溢出口３０から溢れ出て外周流路部１２に流れ落ちるようになっている。 As shown in FIG. 6, a sealing tub portion 11 ′ for collecting drainage flowing from above is detachably attached to the attachment portion 18 formed on the bottom surface of the trap body 8. As shown in FIG. 8, the sealed water trough 11 ′ has a bottomed cylindrical bowl shape with an open top, and a plurality of overflow outlets 30 are formed on the side surface of the sealed water trough 11 ′. Has been. The sealed water stored in the sealed water bottle section 11 ′ overflows from the overflow outlet 30 and flows down to the outer peripheral flow path section 12.

図７に示すように、防臭筒２２’の上部には、略円盤状を成すフランジ部２４’が形成されている。フランジ部２４’の中央部に形成された流入口２５には、該流入口２５の中心を挟んで対向配置される内方に突出する２つの摘み片２６’が形成されている。フランジ部２４’の外周縁には、略Ｌ字形状を成す係合凹部３１が２箇所に形成されている。 As shown in FIG. 7, a flange portion 24 ′ having a substantially disc shape is formed on the upper portion of the deodorizing cylinder 22 ′. The inlet 25 formed at the center of the flange portion 24 ′ is formed with two knobs 26 ′ projecting inwardly facing each other across the center of the inlet 25. On the outer peripheral edge of the flange portion 24 ′, engagement concave portions 31 having a substantially L shape are formed at two locations.

また、フランジ部２４’の外周縁を囲むようにゴム製のパッキンリング３２が設けられている。このパッキンリング３２の外周は、図６に示すように、防臭筒２２’がトラップ本体８に取り付けられたときに、トラップ本体８の内面に圧接して水封されるようになっている。更にトラップ本体８における水受椀部１０と外周流路部１２との間には、防臭筒２２’の係合凹部３１が係合される係合凸部３３が突設されている。 Further, a rubber packing ring 32 is provided so as to surround the outer peripheral edge of the flange portion 24 ′. As shown in FIG. 6, the outer periphery of the packing ring 32 is pressed against the inner surface of the trap body 8 and sealed with water when the deodorizing cylinder 22 ′ is attached to the trap body 8. Further, an engagement convex portion 33 that engages with the engagement concave portion 31 of the deodorizing cylinder 22 ′ is provided between the water receiving portion 10 and the outer peripheral flow passage portion 12 in the trap body 8.

図７の部分拡大図に示すように、フランジ部２４’の外周縁に形成された係合凹部３１は、垂直方向に延びる幅広の垂直溝３１ａと、該垂直溝３１ａの上端から水平方向に延設される幅狭の水平溝３１ｂとで構成されており、水平溝３１ｂが垂直溝３１ａよりも長くなるように形成されている。この係合凹部３１に係合される係合凸部３３は、その断面形状が水平方向に長い長円形状を成している。 As shown in the partially enlarged view of FIG. 7, the engaging recess 31 formed on the outer peripheral edge of the flange portion 24 ′ includes a wide vertical groove 31a extending in the vertical direction and a horizontal direction extending from the upper end of the vertical groove 31a. The narrow horizontal groove 31b is provided, and the horizontal groove 31b is longer than the vertical groove 31a. The engaging convex portion 33 engaged with the engaging concave portion 31 has an elliptical shape whose cross-sectional shape is long in the horizontal direction.

また、封水椀部１１’及び防臭筒２２’をトラップ本体８に取り付ける際には、先ず封水椀部１１’をトラップ本体８に形成された取り付け部１８に取り付ける。そして、防臭筒２２’をトラップ本体８に上方から挿入し、防臭筒２２’の筒体２３を封水椀部１１’に遊嵌し、摘み片２６’を摘んで防臭筒２２’を回転させることで、フランジ部２４’の外周縁に形成された係合凹部３１をトラップ本体８に形成された係合凸部３３に係合させて取り付けることができる。 Further, when the sealed water jar part 11 ′ and the deodorizing cylinder 22 ′ are attached to the trap body 8, first, the sealed water bottle part 11 ′ is attached to the attachment part 18 formed on the trap body 8. Then, the deodorizing cylinder 22 ′ is inserted into the trap body 8 from above, the cylinder body 23 of the deodorizing cylinder 22 ′ is loosely fitted into the sealed water bottle portion 11 ′, the knob 26 ′ is picked, and the deodorizing cylinder 22 ′ is rotated. Thus, the engagement recess 31 formed on the outer peripheral edge of the flange portion 24 ′ can be engaged with the engagement projection 33 formed on the trap body 8 and attached.

尚、図７の部分拡大図に示すように、係合凹部３１を構成する水平溝３１ｂが垂直溝３１ａよりも長く形成され、かつ垂直溝３１ａが幅広で水平溝３１ｂが幅狭に形成されていることで、係合凹部３１に多少のゴミ等が詰まっても、係合凸部３３が係合凹部３１に容易に係合できるとともに、防臭筒２２’をトラップ本体８に確実に固定できる。 As shown in the partial enlarged view of FIG. 7, the horizontal groove 31b constituting the engaging recess 31 is formed longer than the vertical groove 31a, the vertical groove 31a is wide, and the horizontal groove 31b is formed narrow. As a result, even if the engaging recess 31 is clogged with some dust, the engaging protrusion 33 can be easily engaged with the engaging recess 31 and the deodorizing cylinder 22 ′ can be securely fixed to the trap body 8.

尚、図６に示すように、防臭筒２２’がトラップ本体８に取り付けられると、封水椀部１１’の上端縁の全域が防臭筒２２’のフランジ部２４’の下面に当接され、封水椀部１１’の底面が取り付け部１８の上面に当接した状態で固定される。つまり、本実施例２における封水椀部１１’にあっては、取り付け部１８に取り付けられた状態において上端縁がフランジ部２４’の下面に当接する高さを有するとともに、側面における上端縁よりも下方に複数の溢出口３０が形成されており、これらフランジ部２４’と封水椀部１１’とにより浮上防止手段が構成されていることで、封水椀部１１’から外周流路部１２に流れ落ちる排水を常に速やかに流すことができる。 As shown in FIG. 6, when the deodorizing cylinder 22 ′ is attached to the trap body 8, the entire area of the upper end edge of the sealing tub part 11 ′ is brought into contact with the lower surface of the flange part 24 ′ of the deodorizing cylinder 22 ′. It is fixed in a state where the bottom surface of the water seal portion 11 ′ is in contact with the upper surface of the attachment portion 18. That is, in the sealed water trough 11 ′ in the second embodiment, the upper end edge has a height that comes into contact with the lower surface of the flange portion 24 ′ in the state of being attached to the attachment portion 18, and is higher than the upper end edge on the side surface. In addition, a plurality of overflow outlets 30 are formed below, and the flange portion 24 'and the sealed water ridge portion 11' constitute a floating prevention means, so that the outer peripheral flow passage portion is formed from the sealed water ridge portion 11 '. The drainage that flows down to 12 can always flow quickly.

以上、本実施例２によれば、封水椀部１１’の上端縁がフランジ部２４’の下面に当接されることで浮上防止手段が構成され、外周流路部１２に排水が流れ込んだときに、封水椀部１１’が浮上されることを防ぐことができる。そのため封水椀部１１’の底面と取り付け部１８の上面が密着された状態を維持でき、排水に含まれるゴミが封水椀部１１’の底面と取り付け部１８の上面との間に詰まらないようになっている。 As described above, according to the second embodiment, the upper end edge of the sealed water ridge portion 11 ′ is brought into contact with the lower surface of the flange portion 24 ′ to constitute the floating prevention means, and the wastewater flows into the outer peripheral flow path portion 12. Sometimes, it is possible to prevent the sealed water ridge part 11 'from floating. Therefore, it is possible to maintain a state in which the bottom surface of the sealed water bottle portion 11 ′ and the top surface of the attachment portion 18 are in close contact, and dust contained in the drainage is not clogged between the bottom surface of the sealed water bottle portion 11 ′ and the top surface of the attachment portion 18. It is like that.

次に、実施例３に係る排水トラップにつき、図９を参照して説明する。尚、前記実施例１に示される構成部分と同一構成部分に付いては同一符号を付して重複する説明を省略する。図９は、実施例３における排水トラップを示す縦断側面図である。 Next, a drain trap according to Example 3 will be described with reference to FIG. Note that the same components as those shown in the first embodiment are denoted by the same reference numerals and redundant description is omitted. FIG. 9 is a longitudinal side view showing the drain trap in the third embodiment.

図９に示すように、トラップ本体８の取り付け部１８’’には、本実施例における被係合部としての凸部３４が形成されている。封水椀部１１’’の底面には、中央が上方に突出されて底面が凹むように形成された本実施例３における係合部としての凹部３５が設けられている。更に、凸部３４には、雄ネジ３４ａが形成されるとともに、凹部３５には、雌ネジ３５ａが形成されており、凸部３４と凹部３５とは互いに螺合できるようになっている。 As shown in FIG. 9, the mounting portion 18 ″ of the trap body 8 is formed with a convex portion 34 as an engaged portion in the present embodiment. The bottom surface of the sealing water ridge portion 11 ″ is provided with a concave portion 35 as an engaging portion in the third embodiment formed so that the center protrudes upward and the bottom surface is recessed. Furthermore, a male screw 34a is formed on the convex portion 34, and a female screw 35a is formed on the concave portion 35, so that the convex portion 34 and the concave portion 35 can be screwed together.

図９に示すように、封水椀部１１’’をトラップ本体８に取り付ける際には、封水椀部１１’’を回転させながらトラップ本体８の取り付け部１８’’に取り付け、凹部３５を凸部３４に螺合させる。そして、防臭筒２２をトラップ本体８に取り付けられた状態において、封水椀部１１’’の上端縁とフランジ部２４の下面との間には、封水椀部１１’’から溢れ出る排水が通過する間隙（流路）が形成されるようになっている。 As shown in FIG. 9, when attaching the sealing water trough 11 ″ to the trap body 8, the sealing water trough 11 ″ is attached to the attaching part 18 ″ of the trap body 8 while rotating the sealing water trough 11 ″. Screwed onto the convex portion 34.
