[Prior art and its problems]

 As is well known, a bathroom unit is formed by assembling a waterproof floor pan, a wall panel, and a ceiling panel. In recent years, a bathtub placing part and a wash-basin part, which are excellent in workability, are formed separately. Things are the mainstream. In particular, since the number of bathrooms on the upper floors has increased due to changes in lifestyle, preventing the leakage of drainage has become an absolute proposition for this type of bathroom unit. At present, a so-called double-pan system, in which a water-proof pan is formed, has been widely adopted.

[0003] Among those in which the bathtub placement part and the washing place part are formed separately, one end of the bathtub placement part is bulged to form a drainage part, and the drainage of the bathtub is placed in the bathtub placement part. It is also known that it is drained to the drainage part and led to the drainage part, but in this case, even if the bathtub mounting part becomes dirty with drainage, corrodes and leaks, it is often difficult to repair it, Had a problem.

Further, among those in which the bathtub placing portion and the washing place portion are separately formed, a drainage portion is provided at one end of the washing place portion, and the drainage of the bathtub is drained to the drainage portion through a drain pipe. Although it is known to lead the water, in this case, there is a problem that the drainage may leak and accumulate in the pan on the bathtub due to loosening of the connection part of the drainage pipe.

The present invention was devised in view of such a current situation, and an object thereof is to quickly drain the leaked water to the drainage section even if there is water leak in the pan on which the bathtub is placed. Provide a waterproof floor panel for the bathroom that is configured so that the drainage does not flow back into the pan on the bathtub even if the drainage part is blocked and the drainage flows back toward the pan on the bathtub. It is what

【Example】

 Hereinafter, the present invention will be described in detail with reference to an embodiment shown in the accompanying drawings.

As shown in FIG. 1 to FIG. 3, a waterproof floor pan 1 for a bathroom according to this embodiment has a bathtub mounting pan 2 formed separately and a portion above the bottom of the bathtub mounting pan 2. And a washbasin pan 3 having a bottom portion located at.

The bathtub pan 2 is formed in a substantially concave shape having a deep vertical cross-section, a rising part 4 is formed on three sides of the outer peripheral part, and an upper end part of the rising part 4 is formed. A panel receiving piece 5 for fixing a wall panel (not shown) of the bathroom is extended.

Further, the side portion 6 of the bath tub placing pan 2 facing the washing place pan 3 is attached to the rising portion of the side portion 7 of the washing place pan 3 facing the bath placing pan 2 via a waterproof packing 8. As shown in FIG. Incidentally, reference numeral 9 in the drawing is a drainage port formed at the bottom of the bath pan 2.

On the other hand, the washing place pan 3 is formed in a generally concave shape having a shallow vertical cross-section, a rising portion 10 is formed on three sides of the outer peripheral portion, and an upper end portion of the rising portion 10 has A panel receiving piece 11 for fixing a wall panel (not shown) of a bathroom is extended.

A drain portion 12 having a substantially L-shaped vertical cross section is formed on the side portion 7 of the washing place pan 3 facing the bathtub placement pan 2. Of course, the bottom part of the washing place pan 3 is formed with a slope so that the drainage smoothly flows to the drainage part 12.

As is clear from FIGS. 4 to 6, the drain portion 12 has a vertical cylindrical portion 12a having a drain opening 15 at the bottom, and the vertical cylindrical portion 12a from the lower portion to the bathtub mounting portion. A horizontal concave portion 12b extending toward the lower surface of the placing pan 2 and a vertical opening portion of the vertical cylindrical portion 12a and a lower horizontal opening portion of the horizontal concave portion 12b have a substantially L-shaped cross section. The lid 14 formed in the above is detachably fixed.

As shown in FIG. 4, the trap portion 12 is integrally formed with the washing place pan 3, or, as shown in FIG. 5, the drain portion 12 is separated from the washing place pan 3. It may be formed on the body, and the upper portion of the vertical cylindrical portion 12a may be attached to the engaging portion 13 recessed in the washing place pan 3 by engaging it. FIG. 6 is a cross-sectional view of an embodiment in which the drainage section 12 and the washing place pan 3 are separately formed.

The lid 14 has a connection hole 16 formed in a vertical surface portion 14a thereof, and the connection hole 16 has a bathtub drainage, one end of which is connected to a drainage port (not shown) of the bathtub. The other end of the pipe 17 is connected and connected via a pipe socket 19.

A lower portion of the backflow prevention device 20 attached to the drainage port 9 is fitted into the drainage hole 18 formed in the horizontal plane portion 14 b of the lid body 14. The drain hole 18 is formed at a position where it is connected to the drain port 9 formed in the bath pan 2 when the bath pan 2 and the washing pan 3 are connected.

By connecting the drainage port 9 and the drainage hole 18 in this way, even if water leaks from the bathtub drain pipe 17 or the like, the drainage port does not collect in the bathtub placement pan 2 and the drainage port is not collected. Since the water is drained from the drain port 15 to the sewage system through the drainage hole 9 and the drain hole 18, the bath mounting pan 2 is not contaminated by drainage, and corrosion can be prevented.

As shown in FIGS. 6 and 7, the backflow prevention device 20 includes a float cup 21 that is dropped into the drainage port 9 and the drainage hole 18, and a cross-sectional view that is housed in the float cup 21 so as to be vertically movable. It is composed of a convex float 22 and a float cap 23 screwed into the upper opening of the float cup 21. Incidentally, reference numeral 27 in the figure is a waterproof packing.

A drainage outflow hole 24 is formed in the body of the float cup 21, and even if the drainage in the drainage part 12 flows into the float cup 21 through the drainage outflow hole 24, The float 22 rises, the upper end portion 22a of the float 22 is inserted into the opening 25 of the float cap 23, and the step portion 26 formed by the body portion 22b of the float 22 and the upper end portion 22a has the float cap 23. The opening 25 of the float cap 23 is closed by contacting the lower surface of the float cap 23 so that the drainage flowing into the float cup 21 through the drainage outflow hole 24 does not flow into the bathtub mounting pan 2.

Since the waterproof floor pan 1 of the bathroom according to this embodiment is configured as described above, all the drainage flowing through the washing place pan 3 flows into the drainage section 12 and the sewage is discharged from the drainage port 15. The drainage flowing out to the facility and flowing out from the drainage outlet of the bathtub flows into the drainage part 12 through the drainage pipe 17 of the bathtub, and then flows out to the sewerage facility from the drainage port 15 and the drainage of the bathtub. Even if the drainage leaks from the pipe 17 or the like, the drainage is allowed to flow from the drainage port 15 to the sewage system through the drainage port 9 and the drainage hole 18.

If the drain outlet 15 is clogged, the drainage flowing into the drainage portion 12 tends to flow from the horizontal recess 12 b of the drainage portion 12 to the bathtub pan 2. However, since the backflow prevention device 20 is arranged at the drainage port 9 as described above, it is possible to reliably prevent the drainage of the drainage water to the side of the bathtub mounting pan. As a result, It is possible to reliably prevent the problem that the mounting pan 2 is contaminated by the drainage or the smell of the drainage is attached.

The formation position of the drainage portion 12 is not limited to the substantially central portion of the side portion 7 of the washing place pan 3 as in the illustrated embodiment, but may correspond to the environment of the installation place. You may arrange | position on the edge part side of the said side part 7, etc. Further, in the above-described embodiment, the case where the backflow prevention device 20 having the above-described configuration is attached to the drainage port 9 of the bathtub mounting pan 2 has been described as an example, but the present invention is not limited to this. Instead, for example, the backflow prevention device 20 may be attached to the horizontal recess 12b of the drainage portion 12, and the backflow prevention device 20 may be formed of, for example, a check valve.
