2. Description of the Related Art At the entrance of a unit bath (bathroom), in order to prevent people with disabilities and elderly people from wheelchairs from tripping over, the lower frame of the fitting and the bathroom floor are flush with each other to form a barrier-free structure. There is a problem that the drainage of the water easily crosses the lower frame and leaks to the dressing room side. In order to eliminate such a problem, it is known that a drainage groove closed by a grating is provided on the bathroom floor adjacent to the lower frame. However, in this structure, the grating deteriorates the design and the foot contact. A problem arises.

As a structure for solving such a problem, for example, a structure described in Japanese Patent Application Laid-Open No. 8-105272 is known. In this drainage structure, a drainage opening is formed in the lower frame of the fitting, and a drainage gutter that guides the drainage from the drainage opening to the drainage pipe is provided on the lower side of the lower frame, and a large amount of drainage that can not be swallowed by the drainage pipe is provided. Water is prevented from leaking to the changing room by once receiving (storing) it in the drain gutter.

[0004]

In such a conventional bathroom drainage structure, since the drainage gutter is disposed under the lower frame, the lower frame and the drainage gutter are provided with a structure such as a large pull or a base. There is no choice but to place it at a position away from the material to the bathroom side. For this reason, there is a problem that the effective area of the bathroom becomes small, the support of the lower frame becomes insufficient, and the fitting of the fitting attached to the lower frame becomes poor.

The present invention provides a drainage structure for a bathroom which can smoothly guide the drainage around the fittings of the bathroom to a drain pipe without using grating, and a drainage passage or drain gutter formed around the lower frame of the entrance / exit. Its purpose is to provide a drainage structure for a bathroom that facilitates cleaning of the bathroom.
