In the figure, the bathtub pan 1 is integrally formed with a water draining upper piece 1b in a standing manner on the outer periphery of a bathtub mounting surface 1a on which a bathtub 7 can be placed. In the central part, a recess 3 for drainage is integrally formed projecting toward the washing place pan 2, and a drainage connection pipe 4 is integrally formed on the side surface of the recess 3 so as to project toward the wash place pan 2.
In this example, the bathtub pan 1 is formed by injection molding of a thermoplastic resin or the like.

On the other hand, a fitting notch 2a having a shape into which the recess 3 is fitted is formed at the center of the connection side 2b on the bathtub side of the washing pan 2.
By inserting the recess 3 of the bathtub pan into the fitting notch 2a and connecting it at the connecting portion P as shown in FIG. 2, the bathtub pan 1 and the washing pan 2 can be integrated on site. .
In addition, the recessed part 3 is formed in the depth which can ensure the sealing water height a, the side surface 3b is raised from the bottom face 3a to the washing-place pan 2 side, and the drainage connection pipe 4 protrudes and forms in this side face 3b. The sealing water height a is ensured between the lower surface and the bottom surface 3a of the drainage connecting pipe 4.
Further, an upright surface 3c is integrally formed on the opposite side of the side surface 3b from the bottom surface 3a, and the bathtub mounting surface 1a is integrally formed on the upright surface 3c.

  In this recess 3, the partition plate 5 and the sealing member 6 can be installed. The partition plate 5 has a horizontal piece 5b integrally formed from a substantially vertical stand piece 5a to a substantially horizontal shape. The horizontal piece 5b is formed with a fitting hole 5c penetrating vertically. In this fitting hole 5c, as shown in FIG. 2, the bathtub drain H1 of the bathtub 7 can be fitted.

The partition plate 5 is formed as a separate body and can be firmly fixed in the recess 3 by means of welding or the like in the field. If molding is possible, the partition plate 5 is integrated with the bathtub pan 1. This partition plate 5 can also be formed.
In the installed state of the partition plate 5, a passage through which drainage passes is formed between the lower end of the vertical piece 5a and the bottom surface 3a of the recess, and the apron 8 of the bathtub 7 is erected on the vertical piece 5a. Is.

Thus, by installing the partition plate 5 in the recess 3, the recess 3 can be partitioned into a bathtub drain H1 on the bathtub pan 1 side and a washing ground drain H2 on the washing pan 2 side. The waste water from the washing place can be caused to flow into the recess 3 from the washing place drain port H2.
In this way, the inside of the recess 3 is partitioned by the partition plate 5 to form the washing ground drain port H2, and the sealing member 6 can be detachably attached to the washing ground drain port H2. The member 6 has a sealing piece 6b integrally formed by being inclined from a substantially horizontal upper surface piece 6a. The upper surface piece 6a on the left side of the sealing piece 6b is vertically penetrated to have an opening 6c. Is formed.

As shown in FIG. 2, when the sealing member 6 is mounted in the recess 3, the upper surface piece 6a of the sealing member 6 is fitted horizontally above the drainage connection pipe 4, and the sealing piece 6b is a partition plate. 5 is suspended in a slanting manner between the vertical piece 5a and the side surface 4b of the recess 3, and a gap is formed between the lower end of the recess 5 and the bottom surface 3a of the recess, thereby ensuring good sealing water. Will form a sealing surface W.
The sealing member 6 can be removed upward, washed, and slimmed, and can be maintained by the user.

Since the drainage path leading from the pan 1 to the washing pan 2 is formed not in the bathroom but in the bathroom, the probability of water leakage particularly from the bathtub pan 1 side is reduced.

Next, FIG. 3 is an exploded perspective view of the second embodiment, and FIG. 4 is a longitudinal sectional configuration diagram of the assembled state.
In the second embodiment shown in FIGS. 3 and 4, a recess 3 is integrally formed at the center of the connecting side 2 b of the washing pan 2 so as to protrude toward the bathtub pan 1, and the recess 3 is fitted. The fitting notch 1c is formed on the bathtub pan 1 side. In addition, the partition plate 5 and the sealing member 6 are the same as those in the first embodiment.

A drainage connection pipe 4 is integrally formed on the side surface 3 b of the recess 3, and in the assembled state as shown in FIG. 4, the upper end of the rising surface 3 c of the recess 3 is connected to the bathtub installation surface 1 a of the bathtub pan 1. P is connected.
In this 2nd Example, it becomes the construction order which installs the wash-place pan 2 after connecting a drain pipe to the drain connection pipe 4, and installs and connects the bathtub pan 1 after that.

In this way, when the recess 3 for sealing water is provided on the washing pan 2 side, if the depth of the sealing water a of the recess 3 is deeper than the lower surface of the drain connection pipe 4, the bathroom pan 1 and the washing pan 2 Sealed water accumulates below the connection point P, making it difficult for water to leak from the connection point P.
Also in this example, since it is not necessary to fix the drain trap in the field, the number of construction steps can be reduced, and the probability of water leakage from the bathtub pan 1 is reduced.
