Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement in a mounting structure of a sprayer that discharges cleaning water toward a cleaning surface of a sanitary device body such as a urinal.

[0002]

2. Description of the Related Art Conventionally, as shown in FIG. 3, a sprayer mounting structure for a sanitary device has a sprayer 2 inserted into a through hole 1a provided in a sanitary device body 1 such as a urinal, and the spout 2a of the sprayer 2 is attached thereto. The water supply pipe 3 is joined 6 to the sprayer 2 on the back surface 1c side of the sanitary equipment body 1 while facing the cleaning surface 1b side of the sanitary equipment body 1. The sprayer 2 is L
The pipe fitting 4 is formed in the shape of a letter, and the cap 5 is screwed onto the piping fitting 4. The piping tool 4 has a step portion 4a that abuts the back surface 1c of the sanitary equipment body 1 and a screwing portion 4b that is inserted into the through hole 1a. The cap 5 has a step portion 5a that comes into contact with the surface 1d of the sanitary equipment body 1 and a screwing portion 5b that is inserted into the through hole 1a, and forms a water discharge port 2a. The sprayer 2 tightens the screwing portion 5b of the cap 5 to the screwing portion 4b of the pipe fitting 4 so that the peripheral edge of the through hole 1a of the sanitary equipment body 1 is separated by the step portion 4a and the step portion 5a via the packing 7. It is attached so as to be pinched. The washing water led from the water supply pipe 3 is
After passing through the pipes 4 and the water channels 4d and 5c of the cap 5,
The water is discharged from the water discharge port 2a toward the cleaning surface 1b.

[0003]

By the way, there are times when the sprayer 2 needs to be removed and the maintenance inspection performed due to clogging or the like. However, in the conventional sprayer mounting structure for sanitary equipment, after the cap 5 and the pipe fitting 4 are separated and inspected, the cap 5 and the pipe fitting 4 are separated.
It takes a lot of work to rejoin and. Therefore, maintenance and inspection was not easy. Further, when the cap 5 and the pipe fitting 4 are rejoined, the deformed state of the packing 7 is not always the same as before the separation. Therefore, when the cap 5 is tightened, the positional relationship between the discharge port 2a and the connecting portion 6 is distorted. The water discharge port 2a cannot be directed in a predetermined water discharge direction. Therefore, in the conventional mounting structure, the cap 5 and the pipe fitting 4 must be rejoined in a state in which the cap 5 cannot be tightened sufficiently, the mounting of the cap 5 becomes unstable, and the cap 5 rotates with the passage of time. As a result, deviations may occur in the water discharge direction, leading to uneven cleaning.

Therefore, in order to solve the above problems, an object of the present invention is to provide a sprayer mounting structure for sanitary equipment in which separation / joining for maintenance and inspection can be easily carried out and the water discharge direction is always in a predetermined direction. .
