In addition, a rectangular insertion hole 17 that is continuous with the drainage port 15 is provided at the place where the drainage port 15 is provided in the washing area 12, and hot water flowing through the washing field 13 flows into the drainage port 15 through the insertion hole 17. It is like that. In the present embodiment, the insertion hole 17 has a rectangular shape, but is not limited thereto.

  The washing area 12 is inclined so as to be positioned downward as it goes to the drain port 15. By providing this inclination, hot water flowing in the floor pan 1 is easily collected to the drain port 15.

  Further, a drainage channel (not shown) for guiding hot water to the drain port 15 may be provided in the floor pan 1. This drainage channel makes it easy for hot water flowing in the floor pan 1 to flow to the drainage port 15.

  If hot water is attached to the surface of the washing area 12, it is easy to slip, and therefore a slip stopper (not shown) may be provided to prevent falling.

  Although the bathtub side area | region 11 is carrying out planar view substantially rectangular shape in this embodiment, it is not limited to this.

  The washing area 12 is located above the bathtub area 11. Moreover, since there is no weir 2 mentioned later in this embodiment, it has the drooping part 18 toward the downward direction rather than the edge part by the side of the bathtub of the washroom side area | region 12, and the bathtub side area | region 11 and the lower end of the drooping part 18 are connected. Yes.

  In the present embodiment, the weir 2 described later is not provided in the boundary portion 14.

  Since the weir 2 is not provided, the number of necessary members is reduced when the floor pan 1 is manufactured, so that the manufacturing efficiency is improved. Further, when the floor pan 1 is loaded, since there is no weir 2, there is no extra protrusion, and it is easy to load, so that the distribution efficiency is improved.

  As described above, the number of drainage ports 15 is reduced to one, so that the number of necessary members can be reduced as compared with the case where there are a plurality of drainage ports 15. Therefore, piping becomes simple and construction becomes easy.

  Next, a second embodiment will be described based on FIG. In addition, about this embodiment, since it is the same as that of the said 1st embodiment shown in FIG. 1 for the most part, the same code | symbol is attached | subjected about the same structure, description is abbreviate | omitted, and a different part is mainly demonstrated.

  In the present embodiment, the drainage port 15 is provided in the middle portion of the boundary portion 14, and the one side weir 21 and the other side weir 22 are provided on both sides of the drainage port 15 at portions other than the drainage port 15 of the boundary portion 14. Yes. Between the one side weir 21 and the other side weir 22, an intermediate weir 23 having a gap in the lower part is provided for passing hot water flowing into the bathtub side region 11.

  A drain trap 3 is disposed at the drain port 15.

  The weir 2 is formed by one side weir 21, the other side weir 22, and an intermediate weir 23. By forming the weir 2, it becomes difficult for hot water to flow into the bathtub-side region 11, so that scale does not easily occur.

  The intermediate weir 23 is formed in a rectangular body, and the thickness is formed to be equal to the one-side weir 21 and the other-side weir 22, but the height of the intermediate weir 23 is to provide a gap between the drainage trap 3 described later. Formed short.

  The one side weir 21 and the other side weir 22 are connected via an intermediate weir 23. The both side surfaces of the intermediate weir 23 and the one weir 21 and the other weir 22 may be applied with an adhesive. In addition, the connection between the intermediate weir 23, the one weir 21 and the other weir 22 is made such that the length of the gap between the one side weir 21 and the other side weir 22 and the length in the lateral direction of the intermediate weir 23 are substantially equal. Also good.

  After the drain trap 3 is installed at the drain port 15, an intermediate weir 23 is installed so that the drain trap 3 does not come off from the drain port 15.

A bathtub-side drain hole 31 through which the bathtub-side drainage flows is provided on the upper surface of the drain trap 3. In addition, a washing place drain hole 32 through which drainage on the washing place 13 side and hot water from the bathtub side region 11 flows is provided. Further, a sewage discharge pipe 33 is provided on the side surface of the drain trap 3 to discharge the drainage into the sewage pipe. The shape of the drain trap 3 is preferably formed in accordance with the shape of the drain port 15. The drain trap 3 is made of resin, but is not limited to this.

  Although the sewage discharge pipe 33 has a cylindrical shape, the cross-sectional shape thereof is preferably matched with the cross-sectional shape of the sewage pipe.

  The bathtub-side drain hole 31 is disposed on the bathtub side of a portion where the intermediate weir 23 is provided in a plan view of the upper surface of the drain trap 3. In this embodiment, the bathtub-side drain hole 31 is a circular opening, but its cross-sectional shape is preferably matched to the cross-sectional shape of the drain pipe extending from the drain port 15 of the bathtub.

  The washing area side drain hole 32 is disposed on the washing area 13 side of the portion where the intermediate weir 23 is provided in a plan view of the upper surface of the drain trap 3. In the present embodiment, the washing ground side drain hole 32 is a substantially semicircular opening, but is not limited thereto. The hair catcher 4 is attached to the washing area side drain hole 32.

  In the present embodiment, the hair catcher 4 has a substantially semicircular shape, and includes a lower surface portion 42 having a small hole 41 for collecting hair and dust, an upright piece 43 provided on the periphery of the lower surface portion 42, and an upright piece 43.
