DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a drainage structure of a bathroom door provided in a bathroom of a general house or the like, and more particularly to a bathroom door having a waterproof pan forming a floor portion of the bathroom and a lower frame of the bathroom door. Regarding drainage structure.

[0002]

2. Description of the Related Art Today, unit-type bathrooms are widely used as bathrooms in general houses and the like. FIG. 7 shows an example of such a conventional unit-type bathroom. 7A is a plan view of the bathroom, and FIG. 7B is a vertical cross-sectional view taken along the line AA of FIG. 7A. As shown in FIG. 7, in a general bathroom, a step D1 of about 10 cm to 15 cm is provided between the washing place in the bathroom and the floor in the undressing room by standing up around the waterproof pan 100 constituting the floor of the bathroom. Is provided. The provision of the step D1 prevents water from overflowing from the bathroom side to the undressing room side via the bathroom door placed on the rising section of the waterproof pan 100.

[0003] However, water may flow into the upper surface of the bathroom door over the above-described step D1, and such water is drained from the bathroom door. Is formed with a drainage channel R1. Here, conventionally, since the step D1 was formed as described above, it is possible to drain water from the lower frame to the washing place side,
Therefore, the drainage channel R1 of the lower frame was formed so as to communicate from the lower frame to the washing place side.

[0004] On the other hand, in recent years, demand for barrier-free has been increased in consideration of the elderly and the physically handicapped, and demand for bathrooms in which the step between the washing room and the floor of the dressing room has been minimized has increased. Against this background, a bathroom has recently been proposed in which there is no step between the washing room and the floor of the dressing room. An example of such a bathroom is shown in FIG. FIG. 8A is a plan view of the bathroom, and FIG. 8B is a vertical cross-sectional view taken along the line BB of FIG. 8A. In the bathroom shown in FIG.
The steps are eliminated by not setting up the surrounding area. However, in a bathroom where there is no step between the washing place and the floor of the dressing room, there is naturally a fear that water overflows from the bathroom side to the dressing room side via the bathroom door. For this reason, in such a bathroom, the drain water 102 is provided on the four circumferences of the washing place, and the grating 103 is disposed thereon, thereby preventing the water in the bathroom from overflowing into the dressing room. The reason why the drainage grooves 102 are provided on the four circumferences of the washing place is that the bathroom door may be provided at any place around the washing place.

[0005] Even in such a bathroom without a step, a drain R2 is formed in the lower frame of the bathroom door in order to drain the water flowing over the grating and flowing into the bathroom door. In such a bathroom without steps,
It is possible to perform drainage through the grating 103 and the drainage groove 102, and thus the drainage channel R2 of the lower frame is
Like the bathroom door of a bathroom with a step, it was formed so as to communicate from the lower frame to the washing place side.

[0006]

However, in such a conventional bathroom without a step, the grating 103 having a lattice pattern is arranged as shown in FIG. There is a problem that the user feels smaller than the area. This is Grating 10
3 gives an impression that it is weak in strength, gives an impression that it is unsanitary due to drainage, or gives an impression that the grating 103 is not part of the washing place because it has a different pattern from the center of the washing place. This is because the bather does not want to get on the grating 103 by giving.

Further, since the grating 103 has a lattice shape or a shape close to the lattice shape due to its function, it is difficult to change the design of the bathroom. However, there was a problem that the design property of the device was impaired. Further, since the grating 103 has a lattice shape, dirt easily adheres thereto, and the drainage flow may be deteriorated. Therefore, it is necessary to periodically clean the grating 103 around the washing area, which is troublesome. Had a point. For these reasons, there has been a demand for a bathroom having no steps like D1 in FIG. 7 and no grating 103 as in the bathroom in FIG.

However, when the step D1 and the grating 103 are eliminated, there is a problem that the water flowing into the bathroom door cannot be drained to the washing place. In other words, in order to realize a bathroom without the step D1 and the grating 103, a drainage structure of a bathroom door capable of draining inflowing water to a place other than the washing place has been desired.

The present invention has been made in view of such a problem in the conventional drainage structure of a bathroom door, and has as its object to provide a drainage structure of a bathroom door which can drain inflowing water to a place other than a washing place. Aim.
