Is installed in an upright state, a drain port 13 is formed in the bottom portion 12, and a blindfold plate 14 is attached to the drain port 13 so as to cover the drain port 13 entirely.

The blindfold plate 14 is attached to a drainage port member 20 such as a drain fitting provided at the bottom of the handwasher 10 such that the upper surface of the blindfold plate 14 is flush with the bottom 12 of the water tank.
Moreover, it is provided so as to cover the entire upper surface of the drainage port member 20.

FIG. 2 specifically shows the blindfold plate 14. The blindfold plate 14 is made of, for example, a copper alloy such as brass whose surface is plated and has a substantially cylindrical shape with its upper part closed. A disk-shaped flange portion 14a that spreads outward is formed in the upper portion, and a plurality of through holes 14b are formed inside the flange portion 14a. In the present embodiment, four through holes 14b are concentrically provided with four circular holes in the substantially central portion of the flange portion 14. The through holes 14b allow the water accumulated in the hand washing device 10 to drain from the drain fitting 20. It suffices that the water can be drained and the fallen objects can be collected, and the number thereof is arbitrary and the shape may be oval, square, or irregular.

A cylindrical portion 14c connected to the flange portion 14a is formed below the flange portion 14a. A peripheral groove 15 is provided on the lower outer periphery of the cylindrical portion 14c, and a packing 16 is provided in the peripheral groove 15.
I am wearing.

The drainage fitting 20 as a drainage member has a substantially cylindrical shape, and the drainage port 1 is opened at the bottom 12 of the handwasher 10.
It is attached to 3. That is, this drain fitting 20
An upper flange portion 24 and a tubular portion 21 continuously provided below the flange portion 24 and having an external thread 22 engraved on the outer peripheral surface thereof are provided. The tubular portion 21 extends downward and the drainage port of the handwasher 10 is provided. It projects more than 13.

Thus, the male screw 22 is fixed to the fixing nut 23.
The drainage fitting 20 is attached with the fixing nut 23 and the upper flange portion 24 sandwiching the bottom portion 12 of the handwasher. Incidentally, 25 is a washer interposed between the fixed nut 23 and the bottom 12 of the handwasher, and 26 is a seal packing interposed between the drainage port 13 of the handwasher and the flange 24.

Then, the blindfold plate 14 is inserted into the inner peripheral surface of the cylindrical portion 21 from above the drainage fitting 20, and is fitted to the inner peripheral surface of the cylindrical portion 21 by the packing 16 mounted in the peripheral groove 15 of the cylindrical portion 14c. , The blindfold plate 14 is attached and fixed to the drain fitting 20.
