[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. 5 shows an example of such a conventional unit-type bathroom. FIG. 5A is a plan view of a bathroom, and FIG. 5B is a vertical cross-sectional view taken along line BB ′ of FIG. 5A. As shown in FIG. 5, in a general bathroom, a rising pan 12 is provided around a substantially planar main body 11 of a waterproof pan 10 constituting a floor of the bathroom, so that a washing place in a bathroom and a dressing room can be installed. A step D1 of about 10 cm to 15 cm is provided between the floor and the floor. And the step D
1 to provide the rising step 12 of the waterproof pan 10.
Through the bathroom door F placed in the bathroom to prevent water from overflowing from the bathroom side to the undressing room side.

However, water may flow into the upper surface of the bathroom door F over the step D1 as described above, and such water is drained from the bathroom door F. A drain R1 is formed in the lower frame.
Here, conventionally, since the step D1 was formed as described above, it is possible to drain the water from the lower frame to the washing place side. Therefore, the drainage passage R1 of the lower frame communicates with the lower frame to the washing place side. Was formed as follows.

[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. 6A is a plan view of the bathroom, and FIG. 6B is a vertical cross-sectional view taken along the line CC ′ in FIG. 6A. In the bathroom shown in FIG.
No step is provided by not providing a rising step around the periphery of the reference numeral 1. 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 step-less type bathroom, a drain R2 is formed in the lower frame of the bathroom door F in order to drain water flowing over the grating and into the bathroom door. In such a bathroom without a step, drainage can be performed through the grating 103 and the drainage groove 102, and therefore, the drainage passage R2 of the lower frame is provided.
Was formed so as to communicate from the lower frame to the washing place side, similarly to the bathroom door of a bathroom with a step.

[0006]

However, in such a conventional bathroom without a step, the grating 103 having a lattice pattern is arranged as shown in FIG. 6 (a). There is a problem that the user feels smaller than the area. This is Grating 10
3 gives an impression that the strength is weak, 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. From these, the step D1 as shown in FIG.
There has been a demand for a bathroom having no grating and no grating 103 as shown 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 demanded. In such a case, it is conceivable to make the waterproof pan a special structure. However, manufacturing a special waterproof pan undesirably increases the cost of the entire bathroom. Therefore, it has been desired to achieve the above-described drainage structure using an existing waterproof pan, that is, a waterproof pan having a rising portion provided around a substantially flat main body.

The present invention has been made in view of such a problem in the conventional drainage structure of a bathroom door, and a bathroom in which inflowing water can be drained to a place other than a washing place while using an existing waterproof pan. The purpose is to provide a drainage structure for doors.

FIG. 1 is a plan view of a bathroom to which the drainage structure according to the present embodiment is applied, with a bathroom door and a bathroom wall removed, FIG. 2 is a cross-sectional view of the bathroom door with a waterproof pan removed, and FIG. FIG. 4 is an enlarged view around the lower frame of FIG. 3.

In FIG. 1, a dressing room B is provided side by side with a bathroom A to which the drainage structure according to the present embodiment is applied. Here, a waterproof pan (that is, an existing general waterproof pan) 10 having a substantially planar main body 11 having no grating or the like and a rising step 12 is laid below the bathroom A. Then, the bathroom A is set on the main body 11 of the waterproof pan 10.
And a bathtub C is mounted on a part of the upper surface of the main body 11, and another part of the upper surface where the bathtub C is not disposed is a washing place D.

[0015] As shown in FIG.
The waterproof pan 10 is formed in a substantially L-shaped vertical cross-section at four circumferences of the main body 11, and a bathroom wall (not shown) can be freely arranged on the upper surface of the rising step 12. An opening E is formed in the bathroom wall located between the bathroom A and the undressing room B among the bathroom walls arranged in the rising step portion 12. At the position corresponding to the opening E in the rising step 12 of the waterproof pan 10, a notch 14 is formed by cutting the rising step 12. The bathroom door is arranged so as to be substantially accommodated in the opening E or the like. The position of the undressing room B with respect to the bathroom A is not limited to the illustrated one, and may be located at any location adjacent to the washing place D of the bathroom A. Therefore, the position where the opening E is formed (the position where the bathroom door is arranged) is not limited to the illustrated position, and may be formed in any of the ranges shown as the installable range in FIG.

As shown in FIGS. 2 and 3, the bathroom door disposed in the opening E has a pair of door bodies in a frame formed from upper and lower frames 1 and 2 and left and right vertical frames 3 and 4. It is constructed as a folding door type bathroom door that can accommodate 5 and 6. Note that the upper and lower frames 1 and 2 and the left and right vertical frames 3 and 4 of the bathroom door and the support frame 30 described later are formed of an extruded aluminum material.

The lower frame 2 is arranged on the side of the waterproof pan 10 not through the rising step 12 of the waterproof pan 10 but through a notch 14 formed by cutting the rising step 12 as in the prior art. The step between the upper surface of the waterproof pan 10 and the upper surface of the lower frame 2 is minimized. As shown in FIG. 4, four drain grooves 20 a to 20 d extending along the longitudinal direction of the lower frame 2 and extending substantially the entire length of the lower frame 2 are formed in the lower frame 2 of the bathroom door.

The drain groove 20a is formed substantially vertically below the doors 5 and 6, and has a substantially concave shape with its upper surface opened. A rail piece 21 is formed substantially at the center of the drain groove 20a in the viewing direction.

Locks and slidably supports the door bodies 5 and 6. Therefore, when the doors 5 and 6 are opened and closed, the upper surface of the drain groove 20a is almost completely opened, and water flowing from the bathroom A side toward the upper surface of the lower frame 2 can freely flow into the drain groove 20a. Is prevented from reaching the dressing room B. The drain 20a
A drain port 22a communicating between the drain groove and the drain groove 20c described below is formed at a predetermined interval in the finding direction.

The drain 20b is, as shown in FIG.
It is formed at a position near the end of the lower frame 2 on the undressing room B side,
Like the drain groove 20a, it has a substantially concave shape with its upper surface opened. Above the drain 20b, the drain 20b
The groove cover 23 is disposed so as to reach almost the entire length of the groove cover 2.
3 prevents dust and the like from entering the drain groove 20b. 2 and 4, drain openings 22b are formed at predetermined intervals in the longitudinal direction of the groove lid 23, and water traveling over the drain grooves 20a toward the undressing room B passes through the drain openings 22b. And can flow freely into the drainage groove 20b. The groove cover 23 is detachably attached to the lower frame 2 by sliding the operation knob 24. Further, between the drainage groove 20b and a drainage groove 20c to be described later, a drainage port 22c communicating these two grooves is formed at a predetermined interval in the finding direction.

The drain groove 20c is formed as a hollow portion substantially vertically below the drain groove 20b. Here, since the drain port 22a and the drain port 22c are formed as described above, the water flowing into the drain groove 20a passes through the drain port 22a, and the water flowing into the drain groove 20b passes through the drain port 22c. Each can freely flow into the drain 20c. Drain 2
Od is formed as a hollow portion substantially vertically below the drain groove 20a. The drain 20d and the drain 20
A drain port 22d communicating between the two grooves is formed at a predetermined interval in the direction of finding. Therefore drain 2
0c flows into the drain 20d through the drain 22d.
It can flow freely into

Under the drain 20d, the drain 2
Drainage ports 22e communicating between 0d and the outside of the lower frame 2 are formed at predetermined intervals in the finding direction. Therefore, the drain 20
The water that has flowed into d can flow freely below the lower frame 2 through the drain port 22e. For these reasons, the lower frame 2 has drainage grooves 20a to 20d as shown by arrows in FIG.
A drain passage 25 is formed to drain water flowing into the drain grooves 20a to 20d below the lower frame 2 through drain ports 22a to 22e.
