  However, the conventional bathroom drainage structure has a problem that it takes time to drain the water in the bathtub. In a mechanical bathtub, the state where the water in the bathtub is full is a situation where there are bathers. The bather must wait for the drainage to be completed, and in some cases, the bath will be cooled. Therefore, in the mechanical bathtub, it is necessary to drain the water as quickly as possible to shorten the time until the door can be opened and closed.

  Then, this invention is made | formed in view of such a problem, and it aims at providing the drainage structure of the bathroom which can shorten the drainage time in a machine bathtub significantly.

  In order to solve the above problems, a bathroom drainage structure according to the present invention is a bathroom drainage structure including a drainage trap having a trap outlet in a lateral direction, a washing pan, and a bathtub pan on which a bathtub is placed. The bathtub includes two or more drain holes, and the bathtub pan includes a water storage unit that temporarily stores drainage from one drain port of the bathtub on the bathtub pan, and the drain trap. Comprises a guide part for allowing the drainage from the other drainage port of the bathtub to flow into the drainage trap through the bathtub pipe, a trap drainage port for allowing the drainage from the water storage part to flow into the drainage trap, and a deodorizing pipe. The guide portion is disposed in the deodorizing pipe with a direction determined so that a guide portion discharge port for discharging drainage from the guide portion is directed to the trap discharge port.

  As a result, drainage from one drainage port of the bathtub is quickly and preferentially discharged from the bathtub piping directly to the trap discharge port via the guide part, so drainage performance by providing two drainage ports Thus, a drainage structure for a bathroom that can significantly reduce drainage time is realized.

  Here, it is preferable that the guide portion discharge port of the guide portion discharges waste water from a height position below the lower end of the deodorizing pipe toward the trap discharge port, and the guide portion discharge port of the guide portion is a flat surface. It is preferable to have a shape that expands in a fan shape toward the trap discharge port.

  As a result, the wastewater that passes through the guide section is discharged directly to the trap outlet, while the lower side of the deodorizing pipe is blocked to restrict the flow of drainage through the bathtub pan. It is possible to discharge the waste water passing through more quickly, and it is possible to greatly shorten the discharge time.

  Further, the guide portion includes a direction determining rib that protrudes toward the deodorizing pipe, and the direction is determined by matching the direction determining rib with a guide receiver provided on the inner side of the deodorizing pipe. preferable.

  Furthermore, if the said guide part can be attached or detached from the said deodorizing pipe by pulling up upwards, the cleaning property of a guide part and the operativity at the time of construction will become favorable.

  Moreover, this invention is a drainage trap used for the drainage structure of the bathroom provided with a washing-room pan and the bathtub pan in which the bathtub which has two or more drainage ports is mounted, Comprising: From one drainage port of the said bathtub, The waste water from the water storage part that temporarily stores the drainage from the other drain outlet of the bathtub on the bathtub pan flows into the drain trap. A trap drain port, a deodorant pipe, and a trap discharge port in a lateral direction, and the guide unit is disposed in the deodorant pipe, and the guide unit is removed from the trap drain port while the deodorant pipe is attached to the drain trap. It can also be configured as a detachable drain trap.

  As described above, according to the drainage structure of a bathroom according to the present invention, a plurality of drainage ports are provided in a bathtub, and one drainage port is guided from the bathtub pipe to the drainage trap through the guide portion and directly trap drainage. Since the guide part restricts the flow of drainage while discharging it preferentially toward the outlet and temporarily storing it on the bathtub pan from the other drainage outlet, the drainage via the guide part is performed quickly. Thus, drainage performance can be improved and, in turn, drainage time can be greatly shortened.

It is a figure which shows the structure of the drainage structure of a bathroom. It is a figure which expands and shows a drain trap part. It is a figure which shows the structure of a trap main body. It is a top view of a guide part. It is AA sectional view taken on the line of a guide part.

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

  FIG. 1 is a diagram illustrating a configuration of a drainage structure of a bathroom.

  The bathroom drainage structure 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 includes a first drain 32 for draining to the drain trap 10 via the bathtub pipe 11 and a plurality of drains of a second drain 33 for draining to the water storage unit 21 on the bathtub pan 20. It has.

  The bathtub pan 20 includes a water storage unit 21 that is a space for temporarily storing drainage from the second drainage port 33 of the mechanical bathtub 30. Here, the water storage unit 21 is formed by providing a step with the washing pan 40 so that the bathtub pan 20 is positioned lower than the washing pan 40 so that drainage can be stored on the bathtub pan 20. The waste water temporarily stored in the water storage unit 21 is sequentially discharged from the trap drain port 17. In FIG. 1, the drainage from the second drainage port 33 of the mechanical bathtub 30 is configured to flow directly to the water storage unit 21, but is guided to the bathtub pan 20 in order to prevent the falling sound of drainage onto the bathtub pan 20. Piping may be provided.

  The drain trap 10 is installed at a boundary portion 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 wastewater guided from the first drain port 32 of the mechanical bathtub 30 to the drain trap 10 via the bathtub pipe 11 from a height position below the lower end of the deodorizing pipe 13. Although the bathtub piping 11 is composed of a hard tube, a flexible tube such as a vinyl tube may be partially used. Drainage from the first drain port 32 of the mechanical tub 30 is guided to the underfloor pipe 41 under the wash basin pan 40 through the guide portion 12, and drainage from the second drain port 33 of the mechanical tub 30 is trap drainage. It is led to the underfloor piping 41 through the port 17. That is, the trap drainage port 17 is a dual-purpose drainage port into which drainage from the wash basin pan 40 and drainage from the water storage unit 21 on the bathtub pan 20 flow.

  FIG. 2 is an enlarged view of the drain trap portion, and shows the configuration of the trap body.

  The drain trap 10 includes a deodorizing pipe 13 and has a running trap structure including a trap discharge port 16 in the side surface direction.

  The upper end of the deodorizing pipe 13 is installed in the trap drain 17, and guides the waste water flowing from the trap drain 17 into the drain trap 10. The lower end of the deodorizing pipe 13 is disposed in a drainage water pool called sealed water in the drain trap 10, so that a full water portion by sealing water is placed on the flow path from the trap drain 17 to the trap outlet 16. To prevent odors from flowing backward from the trap outlet 16 to the trap outlet 17.

  Further, the drain trap 10 includes a guide portion 12 having a lower end bent toward the trap discharge port 16 in a front view, and the guide portion 12 drains into the trap from above the deodorizing pipe 13 (of the mechanical bathtub 30). The drainage from the first drain port 32 is directly discharged toward the trap discharge port 16 from the same height as the lower end of the deodorizing pipe 13 or from below. The guide portion 12 includes a direction determining rib 14, and the drain direction of the guide portion discharge port 15 is determined by aligning the direction determining rib 14 with a guide receiver 13 a provided inside the deodorizing pipe 13. A guide portion 12 is attached to the main body of the drain trap 10. In addition, if the guide part 12 is pulled up vertically from the trap drain 17 with the deodorizing pipe 13 attached to the drain trap 10, the guide 12 can be removed from the drain trap 10, and the guide part can be removed from the trap drain 17. It is preferable in terms of cleanability and operability that 12 can be attached to the deodorant pipe 13 to be detachable.

  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 AA.

  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 square shape (fan shape) in plan view, and the drainage performance of the guide portion 12. In addition, the drainage from the bathtub pan 20 (drainage from the second drainage port 33 of the mechanical bathtub 30) is restricted so as to block the lower side of the deodorizing pipe 13. The drainage from the first drainage port 32 via the bathtub pipe 11 and the drainage from the second drainage port 33 via the water storage part 21 and the trap drainage port 17 on the bathtub pan 20 are simply performed by the single drainage trap 10. If it processes, the significance which makes the drain of the mechanical bathtub 30 plural will fade. Since the drain trap 10 simultaneously processes the drainage from the bathtub pipe 11 and the drainage from the bathtub pan 20, the drainage from the bathtub pipe 11 becomes slower as the drainage increases in the water storage portion 21 on the bathtub pan 20. In this respect, in this embodiment, the guide portion 12 is disposed in the deodorizing pipe 13 so that the guide portion discharge port 15 faces the trap discharge port 16 so that the guide portion 12 can be oriented. Drainage performance is improved by making it the shape which spreads toward the exit 16 side. That is, the guide part 12 urges the drainage from the bathtub pipe 11 to flow toward the trap discharge port 16 rather than the drainage from the water storage part 21 on the bathtub pan 20, and the drainage from the bathtub pipe 11 is preferentially processed. It is like that. In this way, by limiting the speed of drainage from the water storage unit 21 on the bathtub pan 20 and speeding up drainage from the bathtub piping 11, two bathtub drains of the first drain port 32 and the second drain port 33 are provided. The water in the bathtub is quickly discharged from the mouth, and the drainage performance is improved by the amount of drainage outlets.

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

  Thus, 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 routed from the bathtub pipe 11 via the guide portion 12 to the drainage trap. 10, the drainage from the other drainage port is temporarily stored in the water storage unit 21 on the bathtub pan 20 and led from the trap drainage port 17 to the drainage trap 10 without passing through the guide unit 12. The guide portion 12 is oriented by a direction determining rib 14 and a guide receiver 13 a provided in the deodorizing pipe 13 so that the drainage from the guide portion discharge port 15 is directed to the trap discharge port 16 on the side surface of the drain trap 10. It is made and attached in the deodorizing pipe 13. At this time, the guide portion discharge port 15 spreads in a fan shape toward the trap discharge port 16 in a plan view and directly discharges the waste water from the height position below the lower end of the deodorizing pipe 13 toward the trap discharge port 16, Since the lower side of the deodorizing pipe 13 is closed to restrict the flow of drainage from the bathtub pan 20, drainage from the bathtub pipe 11 is performed quickly and the drainage performance is improved by providing two drainage ports. You can enjoy it.

  As mentioned above, although the drainage structure of the bathroom which concerns on this invention was demonstrated based on embodiment, this invention is not limited to this, In the range which can achieve the objective of this invention and does not deviate from the summary of invention. Various design changes are possible and all are included within the scope of the present invention.

  For example, although the case where the mechanical bathtub was used is described in the said embodiment, you may use this invention for the drainage structure of the bathroom utilized for what kind of bathtub.

  Moreover, in the said embodiment, although the water storage part 21 was formed on the bathtub pan 20 by providing a level | step difference between the washing-room pan 40 and the bathtub pan 20, the tank for water storage on the bathtub pan 20 separately. It may be prepared as a water reservoir.
