Description

[Technical Field]

[0001] The present disclosure relates to a toilet faucet drain unit. [Background technology]

[0002] Traditionally, hand-washing basins in toilet rooms are installed above a flushing tank at the rear of the toilet, and the water used to flush the toilet is used to wash hands after using the toilet. However, since the wastewater from the hand-washing basin is then used to flush the toilet, people are reluctant to wash their hands with detergents, etc. In addition, toilets that do not have a flushing tank at the rear of the toilet are becoming more common. For this reason, in recent years, there has been an increase in the number of toilet rooms 100 that are equipped with a separate hand-washing basin 30 in addition to the toilet faucet, as shown in Figure 6.

[0003] In this case, it is common to install a hand-washing side drainage path 34 for draining hand-washing wastewater from the hand-washing basin separately from the toilet side drainage path for draining toilet wastewater from the toilet, but this method requires piping work inside the building and is time-consuming, so recently it has been considered preferable to merge the hand-washing side drainage path 34 for draining hand-washing wastewater from the hand-washing basin 30 with the toilet side drainage path so that hand-washing wastewater and toilet wastewater can be drained together (for example, Patent Document 1).

[0004] Incidentally, in a toilet in which hand-washing drainage and toilet drainage can generally be flushed together, including in Patent Document 1, when a separate hand-washing basin is not provided in the toilet room 100, and the hand-washing side drainage path 34 is not connected to the hand-washing side drainage path connection part 6, as shown in Figure 7, the hand-washing side drainage path connection part 6 of the toilet is covered by a cap 51 and a gasket 52 that are separate from the hand-washing side drainage path connection part 6, thereby preventing backflow of toilet drainage flowing through the toilet side drainage path and leakage of odors.

[0005] Figure 7 shows the means for separating the trap section storage section 3 from the outside of the drainage unit at the hand-washing side drainage path connection section 6. As shown in Figure 7, conventionally, this was separated by packing 52 and cap 51, and when a hand-washing basin 30 was installed in the toilet room 100, cap 51 and packing 52 were removed and the hand-washing side drainage path 34 was connected.

[0006] [Patent Document 1] Japanese Patent Application Laid-Open No. 2008-291612 Summary of the Invention [Problem to be solved by the invention]

[0007] However, if the lid is provided by cap 51 and packing 52 that are separate from hand-washing side drainage path connection portion 6, the manufacturing costs and assembly steps for producing cap 51 and packing 52 are inconvenient for the manufacturer.

[0008] In view of the above-mentioned problems, the present disclosure aims to provide a faucet toilet drainage unit that reduces the manufacturing costs and assembly man-hours for manufacturing the cap 51 and the gasket 52. [Means for solving the problem]

[0009] The faucet toilet drainage unit of the present disclosure comprises a toilet side drainage path connection portion that can be connected to a toilet side drainage path through which toilet drainage from the toilet bowl flows, a hand wash side drainage path connection portion that can be connected to a hand wash side drainage path through which hand wash drainage from the hand wash basin flows, a drainage junction portion where the toilet drainage and the hand wash drainage join together, and a sealing portion that separates the inside and outside of the hand wash side drainage path connection portion, and the sealing portion and the hand wash side drainage path connection portion are molded as a single unit. [Effects of the Invention]

[0010] In the faucet toilet drainage unit according to the present disclosure, the sealing portion that separates the inside and outside of the hand-washing water drainage path connection portion is molded integrally with the hand-washing side drainage path connection portion. This makes it possible to separate the inside and outside of the hand-washing water drainage path connection portion without the need for a separate part, and it is possible to manufacture the faucet toilet drainage unit while reducing the cost of parts and assembly man-hours.

[0012] Hereinafter, embodiments of the faucet toilet drainage unit according to the present disclosure will be described with reference to the drawings. Note that the embodiments disclosed below are all examples and are not intended to impose any limitations on the faucet toilet drainage unit according to the present disclosure.

[0013] In addition, in the embodiments disclosed below, more detailed explanation than necessary may be omitted in order to avoid unnecessary redundancy in the explanation and to facilitate understanding by those skilled in the art.

[0014] (Overall composition) FIG. 1 is a cross-sectional view showing a faucet toilet drainage unit 1 according to an embodiment of the present disclosure.

[0015] This first embodiment discloses a movable trap type faucet toilet drainage unit 1. The faucet toilet drainage unit 1 is covered by a case body 2, and a trap section 4 is housed inside the case body 2. The trap section 4 will be described later.

[0016] The case body 2 is preferably of an airtight structure to prevent odor leakage from the sewer pipe.

[0017] In the faucet toilet drainage unit 1 shown in Figure 1, the case body 2 has a through-hole 5 through which the trap section 4 passes, with one end of the trap section 4 exposed to the outside of the case body 2. In this case, the upstream opening 4a of the trap section 4 is exposed to the outside of the case body 2.

[0018] One end of the trap section 4 exposed to the outside of the case body 2 becomes the toilet-side drainage path connection section 7. The toilet-side drainage path connection section 7 is connected to a toilet-side drainage path 35 provided in the toilet bowl (not shown) of the toilet body 31 (see Figure 7), and the water stored in the toilet body 31 flows from the upstream opening 4a of the trap section 4 into the trap section storage section 3, which is inside the faucet toilet drainage unit 1. Furthermore, the trap section 4 does not necessarily have to pass through the case body 2, and may be completely stored inside the case body 2.

[0019] In this case, toilet wastewater or accumulated water that has passed through the through-hole 5 of the case body 2 flows into the trap portion 4 from the upstream opening 4 a of the trap portion 4 .

[0020] Hereinafter, the side of the faucet toilet drainage unit 1 facing the toilet body 31 will be referred to as the front side, and the side opposite the toilet body 31 will be referred to as the rear side of the faucet toilet drainage unit 1.

[0021] The case body 2 is also provided with a hand-washing side drainage path connection 6. A hand-washing side drainage path 34 (see FIG. 6) extending from a hand-washing basin 30 provided in the toilet room 100 is connected to the hand-washing side drainage path connection 6, and the hand-washing drainage water discharged from the hand-washing basin 30 flows into the trap portion storage section 3 inside the faucet toilet drainage unit 1.

[0022] Figure 2 is a cross-sectional view of the upper part of the faucet toilet drainage unit 1. The hand-washing side drainage path connection part 6 has a cylindrical structure, and inside the hand-washing side drainage path connection part 6 there is provided a sealing part 10 that separates the trap part storage part 3 from the outside of the faucet toilet drainage unit 1. The sealing part 10 will be described later.

[0023] 1, the case body 2 is further provided with a drain outlet 8. Toilet wastewater flowing from the downstream opening 4b of the trap section 4 into the trap section housing section 3 and hand wash wastewater flowing from the hand wash side drainage path 34 into the trap section housing section 3 are discharged to the outside of the faucet toilet drainage unit 1 through the drain outlet 8.

[0024] At this time, the toilet wastewater discharged from the downstream opening 4b and the hand wash wastewater discharged from the hand wash side drainage path 34 merge inside the trap portion storage section 3. This merging point is the wastewater junction 9. The wastewater junction 9 is often located near the drain outlet 8, but it may be located away from it.

[0025] In the embodiment shown in FIG. 1, the drain port 8 is provided on the bottom surface 1a of the toilet drain unit 1, that is, on the floor side.

[0026] By providing the drain outlet 8 on the bottom surface portion 1a, it is possible to utilize gravity and efficiently discharge toilet wastewater and hand washing wastewater.

[0027] Furthermore, the hand-washing drainage path connector 6, the toilet-side drainage path connector 7, and the drain outlet 8 are preferably formed in a cylindrical shape. Furthermore, although a circular cylindrical shape is preferable, they may be in a cylindrical shape other than a circular shape, or may be in a shape other than a cylindrical shape. For example, they may be in an oval or rectangular shape.

[0028] Furthermore, it is preferable that the hand-washing side drainage path connection part 6 is provided at a higher position than the drain outlet 8. This makes it easier for the hand-washing drainage water that flows from the hand-washing side drainage path 34 into the trap part storage part 3 to flow into the drain outlet 8.

[0029] The hand-washing side drainage path connector 6 is preferably provided on the rear side of the faucet toilet drainage unit 1. This makes it easier to connect the hand-washing side drainage path 34 extending from the hand-washing basin 30 without the toilet body 31 getting in the way.

[0030] Furthermore, since the toilet-side drainage path connector 7 is connected to the toilet body 31, the front side, which is on the toilet body 31 side, is preferred.

[0031] However, the arrangement of the toilet-side drainage path connector 7, the hand-washing-side drainage path connector 6, and the drain outlet 8 is not limited to the above embodiment, and may be on other surfaces.

[0032] The faucet toilet drainage unit 1 shown in Figure 2 is provided with a shielding portion 36. The shielding portion 36 will be described later.

[0033] As shown in Figure 1, the movable trap type faucet toilet drain unit 1 has a trap portion 4 whose free end 4c rotates up and down, and when the free end 4c of the trap portion 4 faces upward, water can be collected in the toilet bowl portion (not shown), and when the free end 4c of the trap portion 4 faces downward, water can be drained from the toilet bowl portion (not shown) and waste can be discharged from the toilet bowl portion (not shown). When the free end 4c of the trap portion 4 faces downward, collected water in the toilet bowl portion (not shown) flows into the trap portion 4 and into the drain port 8 where it is discharged.

[0034] The trap section 4 is a tubular member with a bellows structure, one end of which is a toilet-side drainage path connector 7 connected to the toilet body 31, and the other end of which is a free end 4c that can rotate up and down. The free end 4c is rotated up and down by a drive device 4d.

[0035] As shown in FIG. 6, the hand-washing-side drainage path 34 extending from the hand-washing basin 30 is connected to the hand-washing-side drainage path connection portion 6 of the faucet toilet drainage unit 1.

[0036] As a result, the hand-washing wastewater generated by washing hands in the hand-washing basin 30 passes through the hand-washing side drainage path 34 and flows into the trap section storage section 3 inside the faucet toilet drainage unit 1 from the hand-washing side drainage path connection section 6. The flowing-in hand-washing wastewater merges with the toilet side drainage that is discharged from the downstream opening 4b of the trap section 4 at the drainage junction. The merged water is discharged from the drain outlet 8 into the drainage path (not shown).

[0037] (Main part configuration) 3A and 3B are enlarged views of the hand-washing-side drainage path connection part 6 as seen from the outside of the faucet toilet drainage unit 1. More specifically, Fig. 3A is a front view, and Fig. 3B is a cross-sectional view as seen from the side.

[0038] Inside the hand-washing side drainage path connection part 6, a sealing part 10 is provided which separates the trap part storage part 3 inside the faucet toilet drainage unit 1 from the outside of the faucet toilet drainage unit 1.

[0039] The sealing portion 10 is provided inside the hand-washing side drainage path connecting portion 6 and is connected to the inner periphery 6a of the hand-washing side drainage path connecting portion 6.

[0040] By providing the sealing portion 10, when the hand-washing side drainage path 34 is not connected to the hand-washing side drainage path connection portion 6, such as when there is no hand-washing basin 30 in the toilet room 100, it is possible to prevent odors from the toilet drainage from leaking to the outside through the hand-washing side drainage path connection portion 6.

[0041] Furthermore, the sealing part 10 is not provided as a separate part from the hand-washing side drainage path connecting part 6, such as a cap 51 (see FIG. 7), but is molded integrally with the hand-washing side drainage path connecting part 6.

[0042] This makes it possible to save the cost of parts and manufacturing steps required to manufacture the sealing portion 10 as a separate body.

[0043] When a conventional faucet toilet drainage unit 1 as shown in Figure 7 is separated by a cap 51, the cap 51 has the advantage of being able to be opened and closed repeatedly, but once the hand-washing side drainage path 34 is connected, it is rarely removed, and once removed, the cap 51 is rarely put back on.

[0044] Therefore, by integrally molding the sealing portion 10 with the hand-washing-side drainage path connecting portion 6, costs can be reduced and no disadvantages arise.

[0045] On the other hand, in case the connection between the hand-washing side drainage path connection part 6 and the hand-washing side drainage path 34 becomes unnecessary, for example by removing the hand-washing basin installed in the toilet room 100, the inside of the hand-washing side drainage path connection part 6 may be configured to use a cap 51 and a gasket 52 to again separate the trap section storage part 3 from the outside of the faucet toilet drainage unit 1.

[0046] 2, 3A, and 3B, a knob portion 11 is provided on the upper side of the sealing portion 10 when viewed from the front. The knob portion 11 extends from the sealing portion 10 so as to protrude outward from the faucet toilet drainage unit 1. By grasping and pulling the knob portion 11, the sealing portion 10 can be detached from the hand-washing side drainage path connection portion 6. This opens up the path connecting the outside of the faucet toilet drainage unit 1 to the trap portion storage portion 3, and by connecting the hand-washing side drainage path 34 to the hand-washing side drainage path connection portion 6 from the hand-washing basin 30, hand-washing water can be drained through the faucet toilet drainage unit 1.

[0047] The protruding height of the knob portion 11 is molded to a height that fits inside the tube of the hand-washing side drainage path connection portion 6. This prevents the sealing portion 10 from coming off the hand-washing side drainage path connection portion 6 when the knob portion 11 hits or gets caught on other parts, etc., during installation of the faucet toilet drainage unit 1, etc.

[0048] In addition, when the height of the hand-washing side drainage path connecting portion 6 is low, the height may be such that the knob portion 11 protrudes from inside the cylinder.

[0049] Furthermore, as shown in FIG. 3A, the knob portion 11 is formed in a triangular shape in the outer circumferential direction of the hand-washing side drainage path connection portion 6. By forming the knob portion 11 in a triangular shape in the outer circumferential direction of the hand-washing side drainage path connection portion 6, it is easy to grasp with a human hand, and it is easy to remove the sealing portion 10 from the hand-washing side drainage path connection portion 6. In this embodiment, the knob portion 11 is triangular in the outer circumferential direction of the hand-washing side drainage path connection portion 6, but it does not have to be triangular. For example, the cross section when cut perpendicular to the protruding direction may be square or circular. Furthermore, it does not necessarily have to be triangular in the outer circumferential direction, and it may be triangular in the inner circumferential direction, etc.

[0050] By connecting the hand-washing side drainage path 34 to the hand-washing side drainage path connection part 6 with the sealing part 10 detached from the hand-washing side drainage path connection part 6, the hand-washing drainage flows into the trap part storage part 3 inside the faucet toilet drainage unit 1 and is discharged from the drain outlet 8.

[0051] Furthermore, as shown in Figures 3A and 3B, the sealing portion 10 has a thin-walled portion 12 near the connection portion 14 between the sealing portion 10 and the hand washing side drainage path connection portion 6 that is molded thinner than other portions.

[0052] Furthermore, the case body 2 and the sealing portion 10 are integrally molded by injection molding. When integrally molding by injection molding, it is common to narrow the mold at the portion that becomes the thin-walled portion 12 so that the thin-walled portion 12 is molded, but it is also possible to widen the gap when filling the resin and then form the thin-walled portion 12 by compression after molding.

[0053] The width of the thin-walled portion 12 is molded to about 1 mm from the inner periphery 6a of the hand-washing side drainage path connecting portion 6 to the inside. It is preferable to change the width appropriately depending on the size and molding material of the hand-washing side drainage path connecting portion 6.

[0054] By making a portion of the connection portion 14 between the sealing portion 10 and the hand-washing side drainage path connection portion 6 a thin-walled portion 12, it becomes easier to remove the sealing portion 10 from the hand-washing side drainage path connection portion 6. Furthermore, if a knob portion 11 is provided near the thin-walled portion 12, it becomes easier to remove the sealing portion 10, but the knob portion 11 may also be provided near the center of the sealing portion 10.

[0055] Furthermore, the thin-walled portion 12 constitutes the entire connection portion 14 between the sealing portion 10 and the hand-washing side drainage path connection portion 6, but it does not necessarily have to be the entire thin-walled portion 12; it may be only a portion.

[0056] The thickness of the thin-walled portion 12 is preferably 0.1 to 0.4 mm, more preferably 0.1 to 0.3 mm, and even more preferably 0.1 to 0.2 mm.

[0057] The thickness of the portion of the sealing portion 10 other than the thin portion 12 is preferably 0.5 to 1.0 mm, more preferably 0.6 to 0.9 mm, and even more preferably 0.7 to 0.8 mm.

[0058] Furthermore, the width and thickness of the thin-walled portion 12 may be appropriately designed so as to be able to withstand the pressure inside the case body 2.

[0059] A recessed portion 13 is provided below the knob portion 11 of the sealing portion 10. The recessed portion 13 is formed to be thin, similar to the thin-walled portion 12. The thickness of the recessed portion 13 does not need to be exactly the same as that of the thin-walled portion 12, but it is preferable that it be about the same.

[0060] The recessed portion 13 makes it easier to detach the sealing portion 10 from the hand washing side drainage path connecting portion 6.

[0061] Furthermore, it is preferable that the horizontal length of the recessed portion 13 is longer than the horizontal width of the knob portion 11 .

[0062] The vertical length of the recessed portion 13 is set to about 2 mm, but it is desirable to change this as appropriate depending on the molding materials of the hand-washing side drainage path connection portion 6 and the sealing portion 10.

[0063] By having a recessed portion 13 at the bottom of the handle portion 11, it is possible to easily detach the sealing portion 10 from the hand washing side drainage path connection portion 6 by holding the handle portion 11 and applying force in the direction of the recessed portion 13.

[0064] The distance from the bottom end of the knob portion 11 to the recessed portion 13 is preferably about 0.5 mm, but it may be farther or closer than that.

[0065] Furthermore, as shown in Figure 2, even if toilet wastewater whose flow has been obstructed by filth accumulated in the toilet side drainage path 35 or trap section 4 attempts to backflow into the hand-washing side drainage path 34, the shielding section 36 can deflect the toilet wastewater attempting to flow into the hand-washing side drainage path 34 and reduce its force, thereby reducing the risk of toilet wastewater backflowing into the hand-washing side drainage path 34.

[0066] Furthermore, when the hand-washing side drainage path 34 from the hand-washing basin 30 is not connected to the hand-washing side drainage path connection part 6, the sealing part 10 remains connected to the hand-washing side drainage path connection part 6, but there is a slight possibility that the wind pressure when the toilet drain flows will cause the sealing part 10 to break. The shielding part 36 also serves to prevent this wind pressure from being transmitted to the sealing part, and prevents the sealing part 10 from detaching from the hand-washing side drainage path connection part 6 at an unexpected time.

[0067] Next, a faucet toilet drainage unit 16 in which the drain port 8 is configured on the rear side will be described as embodiment 2. Figures 4A and 4B are diagrams showing the faucet toilet drainage unit 16 of embodiment 2. More specifically, Figure 4A is a side cross-sectional view of the faucet toilet drainage unit 16, and Figure 4B is a view of the faucet toilet drainage unit 16 from the rear.

[0068] The second embodiment differs from the first embodiment in the location of the drain outlet 8 and the orientation of the opening of the drain outlet 8. In the following explanation, the same components as those in the first embodiment are given the same reference numerals and detailed explanations are omitted, and only the components that differ from the first embodiment are described in detail.

[0069] Similar to the faucet toilet drainage unit 1, the faucet toilet drainage unit 16 has a shielding part 36 at the hand-washing side drainage path connection part 6 that is inserted into the hand-washing side drainage path connection part 6 and covers the outlet 34a of the hand-washing side drainage path 34 connected to the hand-washing side drainage path connection part 6 when the sealing part 10 is detached from the hand-washing side drainage path connection part 6. Furthermore, the faucet toilet drainage unit 16 is provided with a detour path part 37 that runs from the outlet 34a of the hand-washing side drainage path 34 around the shielding part 36 and communicates with the trap part storage part 3.

[0070] In detail, a step 38 recessed rearward is provided on the rear wall 3a of the trap section storage section 3, and outlet 34a of hand-washing side drainage path 34 is located in the upper region of the rear surface of this step 38, and a hanging wall section 39 is suspended from the upper edge of step 38 on the rear wall 3a to position outlet 34a of hand-washing side drainage path 34, thereby forming shielding section 36. The gap between hanging wall section underside 39a, which is the underside of hanging wall section 39, and step section underside 38a, which is the cross section of the step, forms detour path section 37, and hand-washing wastewater passes through detour path section 37 and flows into drainage junction section 9.

[0071] Furthermore, by providing the bypass path section 37, a path for the hand washing wastewater to flow into the wastewater junction section 9 can be secured.

[0072] The embodiment shown in FIG. 1 may also be provided with a detour path section 37 similar to that shown in FIG.

[0073] In this case, in order to allow the toilet drainage from the trap section 4 to flow as smoothly as possible into the drain outlet 8, the downstream opening 4b of the trap section 4 and the drain outlet 8 are set to be positioned approximately at the same position in the left-right direction, but the position of the hand washing side drainage path connection section 6 is set to be shifted left-right from the positions of the downstream opening 4b of the trap section 4 and the drain outlet 8.

[0074] In other words, the central axis C1 of the hand-washing-side drainage path connection part 6 and the central axis C2 of the drain outlet 8 are set at positions that are offset from each other in the left-right direction. Furthermore, the hand-washing-side drainage path connection part 6 is positioned slightly above and to the left of the drain outlet 8 when viewed from the direction of the trap part 4.

[0075] When flushing the toilet, a small amount of toilet wastewater may splash out rearward from the downstream opening 4b of the trap part 4 while it is rotating downward. By positioning the drain outlet 8 at approximately the same position in the left-right direction as the downstream opening 4b of the trap part 4, the toilet wastewater that splashes out is discharged smoothly from the drain outlet 8 without any obstruction, reducing the risk of waste and the like adhering to the toilet-side drainage path 35.

[0076] On the other hand, as described above, the position of the hand-washing side drainage path connection part 6 is set at a position shifted left and right compared to the positions of the downstream opening 4b of the trap part 4 and the drain outlet 8, thereby reducing the risk of toilet drainage water that flies out from the downstream opening 4b of the trap part 4 while rotating being directly caught on the hand-washing side drainage path connection part 6.

[0077] In other words, this also makes it possible to reduce the risk of toilet-side drainage water backflowing into the hand-washing-side drainage path 34.

[0078] Although the drainage structure used in movable trap toilets has been described in detail above, drainage structures other than those for movable trap toilets may also be used. For example, a faucet toilet drainage unit used in a siphon toilet, as shown in Figure 4, may also be used. Furthermore, siphon jet and siphon vortex types may also be used.

[0079] In the third embodiment of the present disclosure, the drain socket 20 will be described.

[0080] FIG. 5 is a schematic diagram of a drain socket 20. The drain socket 20 is provided with a hand-washing side drainage path connection part 22, a toilet-side drainage path connection part 21, and a drain outlet 23. The drain socket 20 is connected to a toilet faucet drainage unit 1, 16. The toilet has a trap part such as a siphon jet type, siphon vortex type, or movable trap type to prevent the intrusion of odors from the sewer pipe and to flush water into the bowl all at once. In the above-mentioned embodiments, the toilet faucet drainage units 1, 16 in which the trap part and the hand-washing side drainage path connection part 6 are integrated have been described, but in embodiment 3, a toilet faucet drainage unit having a trap part (not shown) and a drain socket 20 will be described.

[0081] As shown in Figure 6, the hand-washing side drainage path 34 extending from the hand-washing basin 30 can be connected to the hand-washing side drainage path connection part 22 of the drain socket 20. The toilet side drainage path connection part 21 is connected to the toilet side drainage path (not shown) extending from the trap part.

[0082] The toilet side drainage path connecting portion 21 may be connected to the toilet side drainage path extending from the trap portion, or a short connecting pipe or the like may be provided between the toilet side drainage path connecting portions 21.

[0083] The hand-washing wastewater that flows into the hand-washing-side wastewater inlet 27 and the toilet wastewater that flows into the toilet-side wastewater inlet 26 join together at the wastewater junction 24. The joined water passes through the drain outlet 23 and is discharged into the drainage path (not shown).

[0084] The internal configuration of the drain socket 20 is not limited to that shown in the drawing. In this embodiment, the interior of the drain socket 20 is configured with a toilet-side drain inlet 26 and a hand-washing-side drain inlet 27, which then join together.

[0085] However, it is not necessary to provide the toilet-side drainage inlet 26 and the hand-washing-side drainage inlet 27, and the inside of the drainage socket 20 may be one integrated space.

[0086] The toilet-side drainage path connection part 21 opens upward, and the hand-washing-side drainage path connection part 22 opens to the side. This configuration makes it easier for the toilet-side drainage to flow, but the openings do not have to be in this direction. For example, the toilet-side drainage path connection part 21 may open to the side, and the hand-washing-side drainage path connection part 22 may open upward.

[0087] A sealing portion 25 is provided inside the hand-washing-side drainage path connection portion 22 and is connected to the inner peripheral portion 22a of the hand-washing-side drainage path connection portion 22. By providing the sealing portion 25, when the hand-washing-side drainage path 34 is not connected to the hand-washing-side drainage path connection portion 22, such as when there is no hand-washing basin 30 inside the toilet room 100, it is possible to separate the inside of the drain socket 20 from the outside of the drain socket 20 and prevent odors from the toilet-side drainage from leaking to the outside through the hand-washing-side drainage path connection portion 22.
