Although the drain pipe 5 is attached to the water receiving tray 4, the drain pipe starting end 5a is set at a height avoiding the lowest part of the water receiving tray 4. This is effective in preventing dust from accumulating in the water tray 4 and blocking the drain pipe starting end 5a with the passage of time.

A water-soluble dye 4a is provided at the lowest part of the water tray 4.
When water is leaked, the water-soluble dye 4a is melted by the water received by the water tray 4 and the colored water seeps out into the washing place 3 so that the water leak can be detected early. is there. The water-soluble pigment 4a may be made of the same material as a watercolor paint, a poster color, or an ink for writing. The water-soluble pigment 4a is easily water-soluble in the case of water leakage, and is usually solid, powder, or gel-like water. It is held at the bottom of the tray 4.

The end 5b of the drainage pipe is provided in the vicinity of the inspection opening 6 on the rising surface 3a of the washing place and at a position concealed by the inspection opening cover 7, which is not visible in normal use and is suitable for design. At the same time, it is preferable for ensuring waterproofness and watertightness without directly receiving water spray such as shower. Moreover, since the end 5b of the drainage pipe is provided at a position higher than the shoe scraper 12 of the door, even if the trap 11 is clogged and water overflows into the washing place 3, the water level of the door scraper 12 is higher than that of the door shoe scraper 12. Since it does not rise, it does not submerge and water does not flow back into the drainage pipe 5.

FIG. 1 shows an embodiment in which a drain pipe end 5b is provided in a portion hidden by the inspection port cover 7. FIG. 2 shows an embodiment in which the inspection port inner lid 7a is provided with the drain pipe end 5b and is hidden by the inspection port outer lid 7b.

The watertightness of the inspection port inner lid 7a is fixed to ensure the watertightness. A drain pipe end 5b is attached between the inner watertight member 8a and the outer watertight member 8b. At this time, in order to drain the water drained from the drain pipe end 5b to the washing place 3, the outer watertight member 8b is installed with a slight gap between the joints.

FIG. 4 shows an embodiment in which the drain pipe end 5b is provided on the shelf portion 7c of the inspection port lid in a portion which is difficult to see in a normal use state and is less likely to be sprayed with water in the shower. The water tray 4 is adhered to the bathtub 2 by the flange 4a, and is further held so as to be wrapped by the heat insulating material 9 of the bathtub. For this reason, it will be more firmly held in the bathtub 2, and it is safe to peel off the adhesive. Even if the adhesive used to bond the flange 4a is squeezed out, the heat insulating material 9 for the bathtub covers up the flange 4a and the flange 4a, so that the appearance of the product is not damaged even if the work is performed slightly rough. Can be improved.
