FIG. 2 is a perspective view of a toilet bowl with a flush water tank apparatus according to an embodiment of the present invention.
In FIG. 2, 1 is a toilet body, and 10 is a washing water tank device. The washing water tank apparatus 10 includes a tank 12 and a lid 14 attached to the upper opening 12a of the tank 12, and a hand washing water discharge pipe 18 is erected on the hand washing bowl 16 formed on the upper surface of the lid 14. ing. Then, the cleaning water stored in the tank 12 is supplied to the toilet body 1 so that a predetermined toilet cleaning operation can be performed.

Next, the internal structure of the washing water tank apparatus will be described with reference to FIG.
In FIG. 3, a ball tap 22 is disposed inside the tank. This ball tap 22 is conventionally known and has a float 23 that moves up and down with the water level in the tank, and the movement of the float 23 is transmitted to a valve body (not shown) of an on-off valve via a link mechanism 24. Thus, the opening / closing valve is opened and closed. The ball tap 22 is supplied with cleaning water from an external water supply source through a water conduit 26.
When the on-off valve is opened, water in the flow path of the ball tap 22 is directly discharged into the tank from the water discharge port 25, and a part of the water supply is supplied to the hand-washing water discharge pipe 18 by a joint described in detail later. . The wash water discharged from the hand wash water discharge pipe 18 is once received by the hand wash bowl 16 and drained into the tank 20 from the drain 20 formed in the center of the hand wash bowl 16. The washing water drained from the drain port 20 is received by a tray 28 provided inside the tank, and drained from there to a place where it does not hit the drain valve device 29.

Next, the fixing structure of the hand-washing water discharge pipe and the structure of the aforementioned joint will be described with reference to FIG.
A male screw is formed on the outer peripheral surface of the cylindrical base end portion 30 of the hand-washing water discharge pipe 18. Then, the base end portion 30 is inserted into the fixing hole 32 of the lid 14 from above, and the washer 34 and the stopper 36 are attached from the lower surface side of the lid 14, thereby fixing the hand washing water discharge pipe 18 to the lid 14. In addition, since the internal thread of the stopper 36 is formed with a female screw that is screwed with the male thread of the base end portion 30, the stopper 36 is screwed into the base end portion 30, so 18 can be firmly fixed.

  Further, a branch port 38 is formed in the middle of the flow path to the water discharge port 25 of the ball tap 22 so that a part of the water supply of the ball tap 22 can be supplied to the hand-washing water discharge pipe. A substantially S-shaped joint 40 is connected to the branch port 38. The joint 40 is provided with a connection port 42 connected to the branch port 40, a tubular hand-washing water supply pipe 44 connected to the base end portion 30 of the hand-washing water discharge pipe 18, and guide means 49 described later in detail. The joint 40 is fixed to the branch port 38 so as to be rotatable around the vertical axis.

Next, the guide means of this embodiment will be described with reference to FIG.
The guide means 49 is formed of a bottomed cylindrical guide tube 50 surrounding the outer periphery of the connection end 45 of the hand-washing water supply pipe 44 and a bottomed cylindrical control tube 52 surrounding the outer periphery of the guide tube 50.
An opening 54 is formed on the bottom surface of the guide cylinder 50, and the guide cylinder 50 is attached so as not to fall from the joint 40 by inserting the hand-washing water supply pipe 44 through the opening 54. Since the inner diameter of the opening 54 is slightly larger than the outer diameter of the hand-washing water supply pipe 44, a minute gap is formed between the opening 54 and the hand-washing water supply pipe 44. The guide cylinder 50 can be tilted with respect to the hand-washing water supply pipe 44 by this minute gap.

  A female screw portion 56 is formed at the lower portion of the restriction cylinder 52 and is screwed and fixed to a male screw portion 58 formed in the joint 40. Therefore, since this regulation cylinder 52 cannot be tilted with respect to the hand-washing water supply pipe 44, it serves to regulate the tilting of the guide cylinder 50 disposed inside the regulation cylinder 52 by a predetermined amount or more.

  A rib 60 is provided on the outer periphery of the connection end 45 at the distal end of the hand-washing water supply pipe 44, and the connection end 45 of the hand-washing water supply pipe 44 and the base end 30 of the hand-washing water discharge pipe 18 are connected. In addition, by contacting the inner side of the base end portion 30 of the hand-washing water discharge pipe 18, a seal is made so as not to leak water from the connection portion between the water supply pipe 44 and the hand-washing water discharge pipe 18.

Below, the function of the guide means 49 of this embodiment is demonstrated.
The guide means 49 is connected to the base end 30 of the hand wash water pipe 18 so that the connection end 45 of the hand wash water pipe 44 is inserted into the base end 30 of the hand wash water pipe 18. When the end portion 30 is connected from above, even if the connecting end portion 45 of the hand-washing water supply pipe 44 and the base end portion 30 of the hand-washing water discharge tube 18 are misaligned, the tiltable guide tube 50 is tilted. Since the base end portion 30 of the hand-washing water supply pipe 18 can be guided to an appropriate position along the inner surface, a smooth connection can be performed. Further, the tilting of the guide tube 50 is regulated to a predetermined amount by the non-tiltable restriction tube 52 provided outside the guide tube 50, so that the connection end 45 of the hand-washing water supply pipe 44 and the base end of the hand-washing water discharge pipe 18 If a large deviation occurs in the position of the portion 30 and the proximal end portion 30 of the hand washing water discharge pipe 18 does not fit inside the guide cylinder 50 even if the guide cylinder 50 tilts by a predetermined amount, the hand washing water supply pipe 44 and the hand washing discharge Connection of the water pipe 18 is blocked.

  Therefore, when there is a large shift between the positions of the hand-washing water supply pipe 44 and the hand-washing water discharge pipe 18, they are forcibly connected, and the connection end 45 of the water supply pipe 44 inserted into the hand-washing water discharge pipe 18 is bent inside. Thus, it is possible to prevent a problem that water cannot be appropriately supplied to the hand-washing water discharge pipe 18 or water is leaked from the connection portion.

Although this embodiment has been described in detail above, this is merely an example. For example, in the present embodiment, the guide cylinder and the regulation cylinder are formed separately from the joint, but may be integrated.
Moreover, you may provide the slit and notch for draining which drains the water collected inside to the exterior in the suitable location of the guide cylinder and regulation cylinder of this embodiment. The present invention can be configured in various forms based on the knowledge of those skilled in the art without departing from the spirit of the present invention.
In addition, the tank 12 and the lid | cover 14 in this embodiment are comprised with the earthenware from a viewpoint of external appearance quality, intensity | strength, and surface hardness.
