Description of the Related Art Recently, in the field of housing equipment, due to consideration for the elderly, the disabled, children, etc., a part of the floor surface is not protruded or lowered, in other words, steps. The so-called barrier-free type, which has been eliminated, has begun to spread. Also in the bathroom part, there is a demand for the development of one having a small step or no step at the entrance, handrail, stepping height, and the like.

For example, in a conventional unit bath, a water stopping structure as shown in FIG. 11 is used, and water is stopped in the dressing room 102 by setting the door riding surface 101 one step higher than the washing place 100 surface. Was a problem because there was a step.

[0004] In order to eliminate the steps, measures have been taken to reduce the entrance steps as much as possible, for example, by laying a lantern in a bathroom washing area. However, in the case of using such a bed, there is a problem in terms of dirt on the floor of the washing room, design, and the like, and it is difficult to completely eliminate the steps.

For this reason, as shown in FIG.
A drainage groove 104 is provided on the side of the nearby washing place 100, and a grating (lid) 105 or the like in which a grid-like hole is formed vertically and horizontally on the groove 104 has been developed. Can be realized.

However, in the case of such a structure, the area of the washing area is reduced and grating for closing the drainage groove is required. Therefore, there is a need to increase the manufacturing cost or to clean the groove, which poses a problem. ing.

Therefore, for example, FIG.
A non-grating structure having no steps and no need for grating has been proposed.
That is, in the former, the groove as described above is abolished, a hole (not shown) is formed in the lower surface of the door 103, and
A groove 106 is provided immediately below the lower frame portion for 03, so that when water overflows from the bathroom, water can be drained into the groove. The latter is provided with a water stop plate 107 that rises when the door 103 is closed.

[0008]

However, in the former type, even if hair, dust, or the like enters the groove immediately below the door, it cannot be cleaned. In the latter type,
Since the water stop plate is always exposed to the outside, there is another problem in terms of appearance, and there is also a problem that the foot or the like contacts the water stop plate to cause injury.

SUMMARY OF THE INVENTION In view of the above circumstances, an object of the present invention is to provide a door structure in a unit bath which is free from clogging with dust and hair, does not require cleaning, and is excellent in appearance. It is.
