【Example】

 Next, an embodiment of the present invention will be described in detail with reference to the drawings. In FIG. 2, 10 is a wash water tank, 12 is a tank body, and 14 is a tank lid having a hand-washing pot 16. A hand-washing water discharge pipe 18 is erected on the hand-washing pot 16 of the tank lid 14.

A ball tap 20 is arranged inside the tank. This ball tap 20 is a conventionally known one, and has a float 22 that moves up and down with the water level inside the tank, and the motion of the float 22 is transmitted to the valve body of the on-off valve via a link mechanism 24, so that the ball tap 20 is opened and closed. The valve is designed to open and close.

From the water supply pipe 26 of the ball tap 20, a resin water guide pipe 30 which is almost entirely made of a bellows pipe extends out from a water discharge port 28 for direct water discharge into the tank. The water guide pipe 30 is connected to the hand-washing water discharge pipe 18.

That is, when the opening / closing valve is opened, the water in the water supply pipe 26 is directly discharged into the tank through the water discharge port 28, and a part of the water supply is discharged to the hand-washing water discharge pipe 18 through the water conduit 30. The water is discharged from the water discharge pipe 18 to the handwash bowl 16 by being guided.

In FIG. 1, reference numeral 32 denotes a water discharge pipe main body made of a metal pipe, which constitutes the main body of the hand washing water discharge pipe 18, and the lower end thereof is located substantially above the upper surface of the hand washing pot 16. A tubular member that constitutes the base end portion 34 of the handwash water discharge pipe 18 is integrally fixed to the water discharge pipe body 32. The water discharge pipe base end portion 34 is provided in a protruding state on the lower surface side of the hand washing bowl 16, and is fixed to the hand washing 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 in the center is fitted and fixed to the lower end of the water discharge pipe base end portion 34.

A tip end portion of the water guide pipe 30 is a tube-shaped connecting pipe portion 42 which is straight in the axial direction, and the connecting pipe portion 42 is held upright by a resin holder 44. There is.

The holder 44 has a hooking portion 46 hooked on the upper end of the wall portion of the tank body 12, and an arm 48 extending toward the inside of the tank by the hooking portion 46. The tip of the arm 48 is provided. A guide cylinder 50 is integrally formed with the portion.

The guide cylinder 50 has a cup shape that surrounds the connection pipe portion 42, and a fitting hole 52 is formed in the bottom portion thereof. It is fitted and fixed to the base end of the.

A thick anti-slip sheet 52 made of foam is attached to the inner surface of the hooking portion 46. The non-slip sheet 52 has a function of absorbing a dimensional error in the thickness of the tank wall based on elastic deformation in the thickness direction.

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

The notch 54 has a function of dropping and discharging the water inwardly of the tank when water leaks out between the rubber cap 40 as a seal member and the connecting pipe portion.

The connecting pipe portion 42 is inserted into the water discharge pipe base end portion 34 through the through hole 38 in the center portion of the rubber cap 40. The connecting 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 portion 116 has a height that does not reach the water discharge pipe main body 104 having a small inner diameter, but in this example, the connection pipe portion 42 is formed to extend upward. The small diameter portion 58 is formed as a small diameter portion 58, and this portion is fitted inside the water discharge pipe main body 32.

In the connection structure of this example, when the tank lid 14 is mounted on the tank body 12, the connection pipe portion 42 is fitted into the water discharge pipe base end portion 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 into the inside.

At this time, when the connecting pipe portion 42 is not properly fitted into the water discharge pipe base end portion 34, the connecting pipe portion 42 is tilted from its root as shown in FIG. 4 (A). In the example, since the guide cylinder 50 is arranged so as to surround the connection pipe portion 42, the stopper action of the guide cylinder 50 prevents the connection pipe portion 42 from tilting or falling more than a certain amount.

At the same time, the water discharge pipe base end portion 34 cannot be properly fitted into the guide cylinder 50, and is in a state of riding on the upper surface of the guide cylinder 50. As a result, the tank lid 14 is lifted at the location where the water discharge pipe 18 is arranged, and is tilted as a whole.

That is, in the case of the connection structure of this example, the tank lid 14 cannot be mounted properly unless the connection pipe portion 42 and the water discharge pipe base end portion 34 are properly connected. It is possible to immediately recognize that the water discharge pipe base end portion 34 and the water discharge pipe base end portion 34 are not well connected to each other, and thus it is possible to effectively prevent erroneous mounting of the tank lid 14.

In this example, the connecting pipe portion 42 is taller than the conventional one. Therefore, when the connecting pipe portion 42 is not properly fitted in the water discharge pipe base end portion 34, The connecting pipe portion 42 of the above state pushes the tank lid 14 upward, which also effectively prevents the tank lid 14 from being erroneously attached.

Further, since the connecting pipe portion 42 is tall as described above, it is easy to visually check the connecting pipe portion 42 when the tank lid 14 is mounted, and there is an advantage that the work is easy to perform.

The cup-shaped guide cylinder 50 also serves to prevent the rubber cap 40 from being discharged from the discharge port at the bottom of the tank to the toilet side when the rubber cap 40 is detached from the base end portion 34 of the water discharge pipe. Fulfill

FIG. 5 shows another embodiment of the present invention. The guide cylinder 60 of this example has a gourd shape in plan view, and two adjacent recesses 64 are defined by a wall portion 62 projecting inward at an intermediate portion.

A fitting hole 66 is formed in the bottom of each recess 64, and any of the fitting holes 66 can be fitted and fixed to the connecting pipe portion 42.

In the case of the guide cylinder 60 of this example, even if the positions of the hand-washing water discharge pipe 18 and the connecting pipe portion 42 come to any position of the fitting hole 66 based on the difference in the size of the tank, etc. One guide tube 60 has the advantage that it can be used

Although the embodiment of the present invention has been described in detail above, this is merely an example. For example, in each of the above examples, the guide tube is formed on the holder side. In this case, it is desirable because the advantage of easy molding of the connecting pipe section or the water guiding tube can be obtained. It is also possible to form it integrally with.

Further, the shape of the guide cylinder may be a shape having a slit or a notch at an appropriate position on the peripheral wall portion, or may be any other suitable shape, etc. The present invention does not depart from the scope of the invention. In, it can be configured in a form in which various changes are made based on the knowledge of those skilled in the art.
