2. Description of the Related Art Conventionally, as described in Japanese Patent Application Laid-Open No. 8-105272, a drain ditch is provided immediately below a bathroom entrance and exit.
There is an entrance / exit structure of a bathroom unit in which a lower frame which is a part of an entrance / exit frame material is provided in a drain. The floor of the bathroom entrance lower frame and the floor of the dressing room connected to the bathroom entrance and the floor of the waterproof pan of the bathroom unit have substantially the same floor height, thereby eliminating the steps at the entrance. In such an entrance / exit structure of a bathroom unit, FIGS.
As shown in (b), there is a structure having a drain groove for drainage immediately below a lower frame of a sash at an entrance and eliminating grating serving as a lid of the drain groove (structure 1).

Further, as shown in FIG. 5, in order to avoid overdraft on the driving side of the building, the position immediately below the lower frame of the sash is shifted to the washing place side to have a drainage ditch. There is also a structure without the lid (structure 2). In such structures 1 and 2, a drain port is provided in the drain to discharge the hot water flowing into the drain to the outside of the bathroom unit at the time of washing, cleaning, or when the hot water in the bathtub overflows. Is connected to the drainage pipe. At that time, in order to ensure the watertightness of the entrance and exit, it is more advantageous that the drainage capacity of the drainage groove is larger.

In order to increase the drainage capacity of the drain as described above, a large-diameter outlet as shown in FIG. 4B or a drain as shown in FIG. It is conceivable to increase the number of drain outlets, but if the number of drain outlets is increased,
Since the number of drainage parts and the number of pipes are increased, it is disadvantageous in terms of cost, workability, and reliability of watertightness as compared with the case where the drainage port is made large in diameter.

[0005] As shown in Fig. 4 (b), in the structure 1 in which the drainage groove is provided directly below the lower frame, if the drainage port is made large in diameter,
There is a problem that the expected size of the lower frame of the entrance sash is increased in proportion to the size of the drainage port, and the lower frame is protruded to the side of the waterproof bread washing area, thereby deteriorating the design. Further, as shown in FIG. 5, in the structure 2 in which the drainage groove is provided so as to be shifted from immediately below the lower frame toward the washing place side, when the drainage hole is made large in diameter, the drainage groove further enters under the floor of the waterproof pan, There is a problem that it is increasingly difficult to clean the inside of the drain.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems, and an object of the present invention is to provide an easy-to-clean entrance / exit structure of a bathroom unit having a good drainage performance and a good drainage performance. To provide.
