【Example】

 Embodiments of the present invention will be described below with reference to the drawings. In this embodiment, the discharge nozzle 3 is attached to the mounting hole 2 provided at the upper part of the bowl surface, and the discharge nozzle 3 is connected via the solenoid valve 5 from the water supply pipe 4 piped on the rear side B of the urinal body 1. An example of a ceramic urinal in which washing water is supplied to the portion 3b is illustrated. As shown in FIG. 2, a bowl surface (not shown) surrounded by an annular rim 7 is provided on the front surface 1a of the urinal body 1, and a discharge nozzle 3 is provided at the upper center of the bowl surface. A human body detection sensor 8 for detecting a human body is provided above the discharge nozzle 3. On the other hand, in the lower part of the urinal body 1, a drainage passage is provided which is guided from the trap to the drainage joint 9.

The discharge nozzle 3 is attached to a mounting hole 2 formed in an upper pottery portion 1c of the urinal body 1 shown in FIG. 1, and is exposed on the front side F of the pottery portion 1c. It is provided with a horizontally long nozzle portion 3a and a cylindrical connecting portion 3b that is arranged so as to project to the rear side B of the pottery portion 1c. A male screw portion 10 is engraved on the outer periphery of the connecting portion 3b. From the rear side B of the pottery portion 1c, a triangular packing 11, a flat plate portion 12a of a support tool 12 described later, and a washer 13 are attached to the male screw portion 10. By tightening the fastening nut (fixture) 14, the discharge nozzle 3 can be fastened and fixed to the pottery portion 1c side. Further, in a state where the fastening nut 14 is fastened to the male screw portion 10 of the connection portion 3b, the tip end side of the male screw portion 10 is projected to the rear side B from the fastening nut 14 and fitted into one end of the L-shaped pipe 15. A cap nut 16 is screwed freely, and a cap nut 17 fitted into the other end of the L-shaped pipe 15 is screwed to a male screw portion 18 projecting outside the solenoid valve 5. As a result, the secondary side of the solenoid valve 5 communicates with the connecting portion 3b of the discharge nozzle 3 via the L-shaped tube 15. Further, the primary side of the solenoid valve 5 communicates with the water supply pipe 4 from the S-shaped pipe 19 shown in FIG. 2 through a water stop plug 20 attached to the back surface 1b of the urinal body 1.

Here, the support tool 12 for supporting the solenoid valve 5 shown in FIG. 1 is a metal having a rectangular flat plate portion 12a and a bent portion 12b bent in a direction perpendicular to the flat plate portion 12a. It consists of metal fittings. The flat plate portion 12a is provided with a fitting hole 21 which is fitted to the connecting portion 3b of the discharge nozzle 3, and the flat plate portion 12a is sandwiched between the back surface portion 1b of the pottery portion 1c and the tightening nut 14. It is fixed. In addition, a pair of insertion holes 23 that can be inserted into a pair of female threaded bosses 22 projecting from the outside of the solenoid valve 5 are formed in the bent portion 12b of the support tool 12, and The electromagnetic valve 5 can be firmly attached to the support 12 by screwing the screw 24 into the female screw of the boss 22 while the boss 22 is inserted into the insertion hole 23 of the bent portion 12b.

On the other hand, on the rear side B of the urinal body 1 shown in FIG. 2, in addition to the solenoid valve 5, a control box 6 with a dry battery that can be taken out to the outside is arranged. The part is connected to the solenoid valve 5 via a lead wire 25, and is also connected to the human body detection sensor 8 via another lead wire 26. The human body detection sensor 8 detects the presence of a human body, When the detection signal is transmitted to the control box 6, the control unit opens the electromagnetic valve 5 based on the detection signal, and the cleaning water is supplied to the discharge nozzle 3 side.

In the above configuration, when fixing the solenoid valve 5 to the pottery portion 1c, the female threaded boss 22 protruding from the solenoid valve 5 is screwed to the bent portion 12b of the support tool 12, and the support tool is also attached. The insertion hole 23 of the flat plate portion 12a of 12 is fitted into the connecting portion 3b of the discharge nozzle 3 and between the back surface portion 1b of the pottery portion 1c and the fastening nut 14 (in this embodiment, between the triangular packing 11 and the washer 13). In addition, the electromagnetic valve 5 can be firmly attached to the connecting portion 3b of the discharge nozzle 3 by tightening the fastening nut 14 on the male screw portion 10 of the connecting portion 3b while sandwiching the flat plate portion 12a. . In addition, after the fastening nut 14 is tightened, the cap nut 16 of the L-shaped tube 15 is fastened to the male screw portion 10 (the portion protruding from the fastening nut 14) of the connecting portion 3b, so that the L-shaped tube 15 is discharged. 3 can be connected to the connecting portion 3b. Here, since the support tool 12 is clamped and fixed between the back surface 1b of the pottery part 1c and the fastening nut 14, the support hole 2 of the discharge nozzle 3 is used to support devices such as the solenoid valve 5 and the like. The tool 12 can be fixed, and it is not necessary to make a prepared hole in the pottery part 1c as in the conventional case. Therefore, it becomes possible to attach not only a double pottery part with a space inside but also a single pottery part, and it is not necessary to make holes in the pottery, fisher anchors, screws, etc. For example, the installation of the solenoid valve 5 is extremely easy. Further, by supporting the control box 6 with a dry battery and the like integrally with the solenoid valve 5 by the support tool 12, there is an advantage that the construction can be further facilitated.

[0012]

[Effect of device]

 According to the present invention, as described above, the discharge nozzle is composed of the nozzle portion facing the bowl surface and the connecting portion protruding to the rear side of the urinal body and fixed to the urinal body side by the fixture. Since a supporting tool for supporting a device such as a solenoid valve is fitted into the connecting portion, and the supporting tool is clamped and fixed between the fixing tool and the rear part of the urinal body, It is extremely easy to attach a support for equipment such as a solenoid valve to the urinal body without making a hole in the urinal body. Even the visible single-layer structure can be easily and firmly installed, and it does not require preparation of holes in the pottery, fisher anchors, screws, etc. Supported by Concern that the dimensions of the hole pitch and the like, such as when you drilled porcelain portion as in the prior art is hardly out accurately even eliminated. As a result, there is an effect that a urinal with excellent workability, high quality and good appearance can be obtained.
