Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to a bathtub floor pan.

<Prior Art> In a floor pan on which a bathtub is placed, the bathwater is once dropped from the bathtub drain port at the bottom of the bathtub onto the bathtub placement surface of the bathtub placement part,
A Japanese-style bathtub that is intended for a Japanese-style bathtub that drains from a drainage port that opens at the boundary with the washroom, and one end of the drainage pipe is connected to the bathtub drainage port and the other end of the drainage pipe is used as a washroom. There is a Western-style type for a Western-style bathtub that is disposed so as to face a drainage port opened at the boundary portion and discharges bath water to the outside of the bathroom.

By the way, in the case of a Japanese-style floor pan, each side of the circumference (water reversal surface)
The bathtub mounting surface is inclined toward the drainage port so that the bathwater can be drained smoothly.In the case of a Western-style floor pan, the drainage pit for drain pipes is recessed on the bathtub mounting surface. The main structure is that it is installed and the inclination of the bath surface is directed toward the drain pit.

<Problems to be solved by the invention> However, in the conventional bathtub-mounted floor pan, in the case of a floor pan intended for a Japanese-style bathtub, the bathtub mounting surface is simply formed in an inclined shape. Therefore, there is a problem in that the bath tub is buried in the drainage water, and hair, scale, and the like mixed in the bath water are easily attached to the bath tub, which causes a strange odor.

Therefore, as described in Japanese Utility Model Laid-Open No. 52-152341, Japanese Utility Model Laid-Open No. 56-68063 serves as a passage for guiding the bath water from the bath drain port to the floor pan drain port in the bathtub mounting portion of the floor pan. There are some that have a concave groove, but this concave groove is only a flat bottom passage that communicates with the drain port, so the bath water that falls from the bath drain port is efficiently discharged to the drain port. However, there is a risk that the water will partially stop in the concave groove, or the bath water that has fallen from the bath drain will be scattered on the surrounding bath surface and wet the bath legs, resulting in unsanitary conditions.

Moreover, floor pans intended for these Japanese-style bathtubs cannot be used as Western-style bathtubs, and even if they could be used,
When a Western-style bathtub is placed, there is a problem in that it is not possible to reliably dispose the drainage pipes connected to the drainage ports of the bathpanes having different protrusion amounts by various Western-style bathtubs to the drainage port of the floor pan.

The present invention has been made in view of the above conventional circumstances, and an object thereof is to provide a bathtub placement type floor pan that exhibits excellent drainage and can stably place both a Japanese-style bathtub and a Western-style bathtub. Especially.

<Means for Solving Problems> The technical means taken to achieve the above-mentioned object is that a drainage guide passage that is gradually inclined from one end side to the other end side of the central portion is provided in the bathtub mounting portion. A drainage pit for collecting water, which is formed on the other end side of the central portion which is the downstream end of the drainage guideway, and has a deeper depth, and which is provided at the boundary with the washing place The drainage pit is connected to a drainage pit having a bottom surface continuous with the bottom of the drainage pit for water collection by connecting the drainage pit for drainage and the drainage pit for water collection between the guide drainage pit and the drainage pit for water collection. The gist is that it is composed of an inclined surface that is inclined at the same angle toward the guide drainage channel and the drainage pit for collecting water.

<Operation> According to the above technical means, the bathtub mounting surfaces on both sides with respect to the water collecting drainage pit and the drainage guide path are bilaterally symmetrical in plan view and in vertical cross section. Therefore, both the Japanese-style bathtub and the Western-style bathtub can be stably placed on the bathtub placement section.

Further, in the case of a Japanese-style bathtub, the drainage guideway that gradually inclines toward the one end of the bathtub placement portion shortens the distance between the bottom of the guideway and the bathtub drainage port, and the bathtub legs for drainage that fall from the bathtub drainage port. Prevent jumping to the side, collect water promptly in the drainage pit for water collection, and discharge it to the drain through the drainage channel. Moreover, even if the bath water splashes on the bath surface during drainage, the splashed water is promptly guided to the drainage pit for collecting water and the drainage guideway by its own inclination.

Furthermore, in the case of a Western-style bathtub, the depth of the communication space consisting of the drainage pit for collecting water and the drainage channel that also serves as a drainage pipe that is recessed from the drainage pit for collecting water toward the drainage port is deep and A wide effective space can be secured between the drainage pit for collecting water and each bottom surface of the drainage channel for both drainage pipe arrangement and the drainage pipe installation space connected to the bathtub drainage port.

<Effects of the Invention> Since the present invention is configured as described above, it is of course possible to mount the bathtub in common regardless of whether it is a Japanese-style bathtub or a Western-style bathtub. In this case, the fall distance of the bathtub drainage from the bathtub drainage port to the drainage guideway immediately below becomes shorter, and the backflow occurs in the drainage pit for collecting water that is formed one step deeper without the fear that the drainage scatters and wets the bathtub legs. Water is efficiently collected without drainage and drained to the drain outlet all at once through the drainage channel that also serves as a drainage pipe, so it is possible to eliminate the dirtiness of the bathtub legs due to sticking of scale, hair, etc. Can drain.

Moreover, even if the bathtub drainage is scattered, the bathtub placement surface on which the bathtub legs are placed is inclined toward the drainage guide path.
There is no risk that the splashed water will be immediately guided to the drainage guideway and wet the bathtub legs.

When a Western-style bathtub is placed, the drain pipe from the bottom of the bathtub is provided by the large effective space secured between the bottom of the bathtub and the bottoms of the drainage pits for collecting water and the drainage pipe. Even in various Western-style bathtubs having different protruding amounts, the drainage pipes can be reliably arranged over the drainage port provided at the boundary with the washing place.
