  Hereinafter, the drainage structure of the bathroom according to the present invention will be described with reference to the drawings.

  FIG. 1 is a view showing a configuration of a drainage structure of a bathroom.

  The drainage structure of the bathroom according to the present embodiment includes a drainage trap 10, a washing pan 40, a mechanical bathtub 30, and a bathtub pan 20.

  The mechanical bathtub 30 is placed on the bathtub pan 20, and includes a door 31 that opens and closes on the washing pan 40 side. The mechanical bathtub 30 has a first outlet 32 for draining to the drainage trap 10 through the bathtub piping 11 and a plurality of outlets for the second outlet 33 for draining to the water reservoir 21 on the bathtub pan 20. Is equipped.

  The bathtub pan 20 is provided with a water storage portion 21 which is a space for temporarily storing the drainage from the second drain port 33 of the mechanical bathtub 30. Here, the water storage section 21 is formed by providing the washing pan 40 with a level difference so that the bath tub 20 is at a lower position than the washing pan 40 so that drainage can be stored on the bath pan 20. The drainage temporarily stored in the water storage unit 21 is sequentially discharged from the trap drainage port 17. In FIG. 1, the drainage from the second outlet 33 of the mechanical tub 30 is configured to drip directly to the water storage section 21, but in order to prevent the falling sound of drainage on the tub pan 20, it is led onto the tub pan 20. Piping may be provided.

  The drainage trap 10 is installed at the boundary between the bathtub pan 20 and the washing pan 40, and includes a guide portion 12 and a deodorizing pipe 13. The guide portion 12 is a member for discharging the drainage led to the drainage trap 10 from the first drainage port 32 of the mechanical bathtub 30 through the bathtub piping 11 from a height position below the lower end of the deodorizing pipe 13. Although the bathtub piping 11 is comprised by the rigid pipe, flexible pipes, such as a vinyl pipe, may be used partially. The drainage from the first outlet 32 of the mechanical tub 30 is led to the underfloor piping 41 under the washing pan 40 via the guide portion 12 and the drainage from the second outlet 33 of the mechanical tub 30 is the trap drainage It is led to the underfloor piping 41 via the port 17. That is, the trap drainage port 17 is a combined drainage port from which the drainage from the washing pan 40 and the drainage from the water storage section 21 on the bathtub pan 20 flow.

  FIG. 2 is an enlarged view of the drainage trap portion, showing a configuration of a trap main body.

  The drainage trap 10 has a deodorizing pipe 13 and has a running trap structure provided with a trap outlet 16 in the side direction.

  The upper end of the deodorizing pipe 13 is installed at the trap drainage port 17, and the drainage flowed in from the trap drainage port 17 is guided into the drainage trap 10. The lower end of the deodorizing pipe 13 is disposed in the drainage water portion of the drainage referred to as sealing water in the drainage trap 10 so that the water-filled portion by the sealing water is provided on the flow path from the trap drainage port 17 to the trap discharge port 16 To prevent backflow of odor and the like from the trap outlet 16 to the trap outlet 17.

  Further, the drainage trap 10 is provided with a guide portion 12 whose lower end is bent toward the trap discharge port 16 in a front view, and the drainage is such that the guide portion 12 flows into the trap from above the deodorizing pipe 13 The drainage from the first drainage port 32 is drained directly from the same height as the lower end of the deodorizing pipe 13 or below to the trap outlet 16. The guide portion 12 includes a direction determining rib 14, and the drainage direction of the guide portion outlet 15 is determined by aligning the direction determining rib 14 with a guide receiver 13 a provided inside the deodorizing pipe 13, The guide portion 12 is attached to the main body of the drainage trap 10. The guide portion 12 can be removed from the drainage trap 10 by pulling the guide portion 12 vertically from the trap drainage port 17 in a state where the deodorizing pipe 13 is attached to the drainage trap 10, and the guide portion from the trap drainage port 17 It is preferable from the viewpoint of cleanability and operability that it is possible to attach and remove 12 to be attached to the deodorizing pipe 13.

  FIG. 4 is a plan view of the guide portion 12, and FIG. 5 is a cross-sectional view of the guide portion 12 taken along line A-A.

  As shown in FIG. 4, the guide portion discharge port 15 of the guide portion 12 on the trap discharge port 16 side has a shape that expands in a V shape (fan shape) in plan view, and the drainage performance of the guide portion 12 And restrict drainage from the bathtub pan 20 (drainage from the second drainage port 33 of the mechanical tub 30) so as to close the lower side of the deodorizing pipe 13. The drainage from the first drainage port 32 via the bathtub piping 11 and the drainage from the second drainage port 33 via the water storage section 21 on the bathtub pan 20 and the trap drainage port 17 are also simply one drainage trap 10. If it processes, the meaning which makes the drainage port of the mechanical bathtub 30 multiple will be diluted. Since the drainage trap 10 simultaneously treats drainage from the bathtub piping 11 and drainage from the bathtub pan 20, drainage from the bathtub piping 11 becomes slower as drainage to the water storage portion 21 on the bathtub pan 20 increases. In this respect, in the present embodiment, the guide portion 12 is disposed so as to be orientable in the deodorizing pipe 13 so that the guide portion discharge port 15 faces the trap discharge port 16, and the guide portion discharge port 15 is further trap discharged in plan view. The drainage performance is improved by making the shape spread toward the outlet 16 side. That is, the guide portion 12 urges the drainage from the bathtub piping 11 to flow toward the trap outlet 16 rather than the drainage from the water storage portion 21 on the bathtub pan 20, and the drainage from the bathtub piping 11 is treated preferentially. It is supposed to be. Thus, by limiting the speed of drainage from the water storage section 21 on the bathtub pan 20 and making drainage from the bathtub piping 11 quick, two bathtub drainages, the first drainage port 32 and the second drainage port 33, can be obtained. The water in the bath is drained quickly from the mouth, and it is possible to obtain the effect of improving the drainage performance by the amount of the increase in the drainage port.

  The orientation rib 14 of the guide portion 12 is a rib formed so as to protrude from the guide portion 12 to the side of the deodorizing pipe 13 in order to determine the drainage direction of the guide portion discharge port 15. The guide portion 12 is attached to the inside of the deodorizing pipe 13 by fitting the direction determination rib 14 to the guide receiver 13 a provided so as to project to the inside of the deodorizing pipe 13. Here, the orientation rib 14 is formed to project in the direction opposite to the drainage direction of the guide portion discharge port 15, but if the drainage direction of the guide portion ejection port 15 can be defined, the direction in which the rib is formed Is not limited to this, and the number of ribs is not limited to one.

  As described above, according to the drainage structure of the bathroom according to the present embodiment, a plurality of drainage ports are provided in the bathtub, and drainage from one drainage port is made from the bathtub piping 11 through the guide portion 12 to trap drainage. It is led to 10, and the drainage from the other drainage port is temporarily stored in the water storage section 21 on the bath tub 20, and is guided from the trap drainage port 17 to the drainage trap 10 without passing through the guide section 12. The guide portion 12 is oriented by the orientation rib 14 and the guide receiver 13a provided on the deodorizing pipe 13 so that the drainage from the guide portion ejection port 15 is directed to the trap ejection port 16 on the side surface of the drainage trap 10. It is made and attached in the deodorizing pipe 13. At this time, the guide portion discharge port 15 fans out toward the trap discharge port 16 side in plan view and discharges drainage directly from the height position below the lower end of the deodorizing pipe 13 to the trap discharge port 16, Since the lower side of the deodorizing pipe 13 is closed to restrict the flow of drainage from above the bathtub pan 20, drainage from the bathtub piping 11 is performed quickly, and drainage performance is improved by providing two drainage ports. It can be enjoyed.
