DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a floor structure of a bathroom unit which is a prefabricated bathroom.

[0002]

2. Description of the Related Art It is desirable to provide an entrance at any position on the outer periphery of a floor pan of a bathroom unit on the floor side of a washing room in view of the layout of a room. For this reason, for example, in the bathroom unit disclosed in Japanese Patent Application Laid-Open No. 8-270237, the outer edge L of the floor surface Y formed on the washing floor 202 of the floor pan 200 is installed in a bathtub as shown in FIG. Except for the part 201 side, it is located on the same horizontal plane, and at any position of the wall placing part 203 provided on the outer periphery of the washing floor part 202 side of the floor pan 200, the door frame for forming the entrance part is installed. Between the floor surface Y and the upper surface of the lower frame portion of the door frame,
An entrance section can be formed.

[0003] In this case, a drain groove 202a covered with a groove cover made of, for example, a grating is provided on the side of the bathtub installation section 201 of the washing floor 202, and an outer edge L1 facing the drain groove 202a is formed on the floor surface Y. Trapezoidal first inclined surface Y1 descending from the bottom toward drain groove 202a;
a from the outer edges L2, L3 at both ends of the first inclined surface Y
On one side, triangular second and third inclined surfaces Y2 and Y3 are provided so as to extend the drain groove 202a side, so that the drain water on the floor surface Y of the washing floor 202 is poured into the drain groove 202a. I have to.

[0004]

However, the floor surface Y
In the floor structure of the bathroom unit as described above in which the top is relatively flat, when a large amount of overflow water from the bathtub is flushed onto the washing floor 202 at a time, the drainage that has passed through the drain 202a is drained. It spreads on the floor surface Y, and the floor surface Y becomes wet, and the entrance / exit portion is the outer edge L of the floor surface Y.
When provided without steps, L1, and L3, there is a problem that drainage that has reached the entrance / exit side tends to flow out to the undressing room side.

For this reason, it is necessary to take measures such as increasing the width of the drain groove 202a or increasing the inclination angle of the first inclined surface Y1 of the floor surface Y. However, if the width of the drain groove 202a is increased, the groove is increased. As the width of the lid increases, the usability and appearance of the bathroom deteriorate, and if the inclination angle of the first inclined surface Y1 or the like is increased, the usability of the bathroom similarly deteriorates.

The present invention has been made in view of the above points, and even when the outer edge of the floor of a washing floor is located on the same horizontal plane except for the bathtub side, the overflow water from the bathtub remains on the floor. An object of the present invention is to provide a floor structure of a bathroom unit that is not easily spread and does not deteriorate usability of the bathroom.

[0007]

According to a first aspect of the present invention, a drainage ditch is formed along the bathtub at the end of the washing tub floor at the side of the bathtub, and the upper surface side of the washing floor is provided. The outer edge of the floor surface formed on the floor is provided on the same horizontal plane except for the drain groove side, and the floor surface descends from the outer edge side of the side facing the drain groove to the drain groove side. A first inclined surface, from the outer edge side of both ends of the drainage groove to the first inclined surface side,
In a floor structure of a bathroom unit having a second and a third inclined surface descending so that a drain groove side is widened, and drainage on the floor surface flows from the outer edge to the drain groove side, A fourth inclined surface descending at a larger inclination angle from the adjacent first, second, and third inclined surfaces to the drain groove side than the floor surface between the second and third inclined surfaces and the drainage groove without any step. It is provided.

According to the present invention, the drainage on the floor surface passes through the first, second, and third inclined surfaces and then flows on the fourth inclined surface, and from the fourth inclined surface, a drain ditch next to the bathtub. The large amount of drainage that flows into the tub and overflows in a short time from the bathtub partially flows directly into the drainage gutter, but most of the drainage flows out onto the floor surface through the drainage gutter. In this case, most of the drainage flowing on the floor is restrained by the fourth inclined surface of the floor, which is more inclined to the drain groove side than other portions, and stops on the fourth inclined surface. , Quickly move to the drain groove side next to the bathtub, and only the remaining one moves to the first, second and third inclined surfaces. For this reason, even if a large amount of drainage overflows from the bathtub in a short time, the entire floor surface does not become flooded, and the first, second and third floors are accordingly reduced.
The inclination angle of the inclined surface can also be small. Further, since the fourth inclined surface of the floor surface is inclined downhill toward the bathtub side, it also functions as a foot stop for getting in and out of the bathtub.

In the present invention, since the outer edge of the floor formed on the floor of the washing place is provided on the same horizontal plane except for the bathtub side, for example, the outside of the floor of the washing pan of the floor pan is provided. Even if a door frame is installed at the location and an entrance is provided, the step between the floor of this washing floor and the floor of the entrance can be kept constant, and the effect of the floor inclination angle for drainage can be achieved. Can be eliminated.

According to a second aspect of the present invention, in the case of the first aspect, the wall panel and the door frame are installed at a position one step lower than the outer edge of the floor outside the washing floor. That is, a wall mounting portion is provided.

According to the present invention, since the lower surfaces of the wall panel and the door frame installed on the wall mounting surface outside the washing floor can be lowered by one step from the outer edge of the floor on the washing floor. The floor surface of the entrance formed by the above can be lowered close to the position of the outer edge of the floor, and the step between the floors at the entrance can be eliminated or reduced.
