In this type of washing tank apparatus, as shown in FIG. 10, when the drainage from the drain hole 240 at the bottom of the hand basin 202 falls directly into the washing water in the washing tank 200, the sound of the falling water is generated. Occurs. This sound of falling water becomes harsh noise.

Therefore, as shown in FIG. 10, conventionally, drainage from the drainage hole 240 is performed by the outer tank 2.
Inner tank 200-2 provided inside 00-1
A noise reduction member 242 is provided for guiding to the inner surface of the wall portion, thereby preventing generation of a sound of drainage from the drainage hole 240.

[0011]

However, when the water pipe holder 232 and the muffling member 242 are separately constructed and mounted on the wall of the washing tank 200, the number of parts for the washing tank apparatus increases. As a result, the cost of the washing tank device becomes higher. In addition, as shown in FIG.
In the case of the double tank structure of -1 and the inner tank 200-2, the inner tank 200-2 is made of resin. In this case, the inner tank 200-2 is easily deformed after molding. This has caused the following inconveniences.

That is, when the inner tank 200-2 is deformed, depending on the shape and arrangement of the floating ball, the floating ball comes into contact with the inner surface of the inner tank 200-2 and generates resistance when the floating ball rises and lowers. A problem arises in that the smooth lifting movement of the ball is hindered. Alternatively, various parts are assembled in a predetermined positional relationship inside the inner tank 200-2.
2 deforms, the relative positional relationship between the internal parts thereof and the inner tank 200-2 is shifted or deviated from a predetermined position, and furthermore, the action lever which rotates integrally with the cleaning handle. May cause interference with the wall of the inner tank 200-2, or the tank capacity may change due to deformation of the inner tank 200-2.

On the upper part of the outer tank 10-1, a ceramic hand basin 12 also serving as a lid is provided, and a hand rinsing spout 14 is provided from the hand basin 12. A drain hole 16 is provided at the bottom of the hand basin 12, and hand water discharged from the hand water spout pipe 14 falls into the washing tank 10 through the drain hole 16.

The ball tap 1 is provided inside the cleaning tank 10.
8 are provided. The ball tap 18 has a valve portion connected to the floating ball 22 via the interlocking arm 20, and opens and closes the valve portion by lifting and lowering the floating ball 22, and performs water supply and water supply stoppage by opening and closing the valve portion. This ball tap 18
Has a spout 24 for supplying water to the washing tank 10.
As shown in FIGS. 2 and 4, from the ball tap 18, a water guide pipe 26 composed of a bellows pipe for supplying water to the hand-washing spout pipe 14 extends. The part is plugged into the hand-washing spout 14.

At the bottom of the washing tank 10, a float valve (drain valve) 28 is provided. This float valve 28
Has a spherical valve body 30 and a valve seat 32, and the valve body 30 is lifted from the valve seat 32 so that the discharge port 3 is formed.

Therefore, the water inside the water receiving cup 42 is not drawn out from the water draining hole 50, and is held inside the water receiving cup 42 as it is.

In this case, the water receiving cup 42 acts as a weight for the valve element 30. Therefore, the valve element 30
When the water in 0 flows out by the amount necessary for the small cleaning, the water is immediately seated on the valve seat 32 and the discharge of the cleaning water from the discharge port 34 is stopped. The switching between the large washing and the small washing by the water receiving cup 42 is described in JP-A-10-131257.
The detailed description is omitted here.

As shown in FIGS. 1 and 2, the inner tank 10-2 has an open shape in which the upper end is not covered by a lid. Thus, in this example,
