[0019]

Next, embodiments of the present invention will be described in detail with reference to the drawings together with comparative examples . In FIG. 2, reference numeral 10 denotes a washing water tank, 12 denotes a tank main body, and 14 denotes a tank lid having a hand basin 16. A hand-washing spout 18 is provided in the hand-washing bowl 16 of the tank lid 14.

A ball tap 20 is provided inside the tank. The ball tap 20 is a conventionally known one and has a float 22 which rises and falls with the water level inside the tank, and the movement of the float 22 is transmitted to the valve element of the on-off valve via a link mechanism 24, whereby the on-off valve is opened. Are designed to open and close.

The water supply pipe 26 of the ball tap 20
A water conduit 30 made of a resin, which is made up of a bellows tube, extends almost entirely from the water outlet 28 for direct water discharge into the tank. 18.

That is, when the on-off valve is opened,
The water in the water supply pipe 26 is directly discharged from the water discharge port 28 into the tank, and a part of the water supply is guided to the hand-washing water discharge pipe 18 through the water supply pipe 30, and is discharged from the water discharge pipe 18 to the hand-washing bowl 16. It has become.

In FIG. 1, reference numeral 32 denotes a main body of the hand-washing spout 18, which is a main body of a spouting pipe made of a metal tube, and a lower end thereof is located substantially on the upper surface of the hand-washing bowl 16. A cylindrical member constituting a base end portion 34 of the hand-washing water discharge pipe 18 is integrally fixed to the water discharge pipe main body 32. The water discharge pipe base end 34 is provided in a protruding state on the lower surface side of the toilet bowl 16, and is fixed to the toilet bowl 16 by screwing a nut 36 into a male screw formed on the outer peripheral surface thereof.

A rubber cap 40 having a through hole 38 at the center is fitted and fixed to the lower end of the water discharge pipe base end 34.

The distal end of the water pipe 30 is formed as a tube-shaped connecting pipe 42 which is straight in the axial direction. The connecting pipe 42 is held upright by a resin holder 44.

The holder 44 has a hook 46 which is hooked on the upper end of the wall of the tank body 12, and an arm 48 which extends inward from the tank.
A guide tube 50 according to a comparative example of the present invention is integrally formed at the tip end of 8.

The guide tube 50 has a cup shape surrounding the connection tube portion 42, and a fitting hole 52 is formed at the bottom thereof. Fitted and fixed to the base end.

A thick non-slip sheet 53 made of foam is adhered to the inner surface of the hook 46. The non-slip sheet 53 has a function of absorbing a dimensional error in the thickness of the tank wall based on the elastic deformation in the thickness direction.

The guide cylinder 50 has a bottom located substantially at the upper end of the tank body 12, and has a water discharge pipe base end 34 fitted therein. A notch 54 is formed in the peripheral wall of the guide cylinder 50 at a position near the center of the tank as shown in FIG.

The cutout 54 has a function of dropping water toward the inside of the tank when water leaks from between the rubber cap 40 as a sealing member and the connection pipe portion 42 .

The connection pipe section 42 is inserted into the through hole 38 at the center of the rubber cap 40 and fitted into the water discharge pipe base end 34. The connection pipe portion 42 is formed such that a fitting portion into the water discharge pipe base end portion 34 is a large diameter portion 56 and a fitting portion into the water discharge pipe main body 32 is a small diameter portion 58.

That is, in the case of the conventional connection structure shown in FIG. 6, the connection pipe 116 has a height that does not reach the water discharge pipe main body 104 having a small inner diameter. In this example, the connection pipe 42 is formed to extend upward. The extended portion is a small-diameter portion 58, which is fitted inside the water discharge pipe main body 32.

In the connection structure of this example, the tank lid 1
4 is mounted on the tank body 12, the connection pipe 4
2 is fitted into the water discharge pipe base end 34 and connected to the water discharge pipe 18. At this time, the guide cylinder 50 performs a guiding action to fit the water discharge pipe base end portion 34 therein.

[0034] When successfully connecting tube portion 42 at that time did not fit into the water discharge pipe proximal end 34, although the connecting tube portion 42 as shown in FIG. 4 (A) is tilted from its root, the In the example, since the guide tube 50 is provided so as to surround the connection tube portion 42, the stopper tube 50 prevents the connection tube portion 42 from tilting or falling over a certain amount.

At the same time, the base end 34 of the water discharge pipe is
0 cannot fit well, and it is in a state of riding on the upper surface of the guide tube 50. As a result, the tank lid 14 is in a state of being raised at the position where the water discharge pipe 18 is provided,
It is in a state of being totally inclined.

That is, in the case of the connection structure of this example, the connection pipe 4
When the tank 2 and the water discharge pipe base end 34 are not connected well, the tank lid 14 cannot be mounted properly, so that the worker cannot connect the connection pipe 42 and the water discharge pipe base 34 well. Can be immediately recognized, so that erroneous mounting of the tank lid 14 can be effectively prevented.

In this example, the connecting pipe portion 42 is made taller than the conventional one. Therefore, when the connecting pipe portion 42 is not properly fitted in the water discharge pipe base end 34, this connecting pipe portion 42 is not slid. The pipe section 42 pushes the tank lid 14 upward, which also effectively acts to prevent the tank lid 14 from being erroneously mounted.

Further, since the connecting pipe portion 42 is taller, the connecting pipe portion 42 can be easily visually checked when the tank lid 14 is mounted, and the work can be easily performed.

The cup-shaped guide cylinder 50 also serves to prevent the rubber cap 40 from being discharged from the outlet at the bottom of the tank to the toilet when the toilet is washed, when the rubber cap 40 comes off the base end 34 of the water discharge pipe. Fulfill.
