Embodiment 1 FIG. 1 to FIG. 4 show an embodiment of the present invention.

First, the overall structure will be described with reference to FIG. In the urinal body 1, the flush water is discharged from the water supply nozzle 2 over the entire bowl surface 3 so that the bowl surface 3
Is to be washed.

At the center of the bowl surface 3 from the upper end,
A human body detector 4 for detecting a human body is provided.

The human body detector 4 is provided with a light projecting element 16 that throws light toward the user's foot and a light receiving element (not shown) that receives the light reflected by the foot, and senses signals from the light receiving element. Based on this, the control unit 5 generates an output, and the electromagnetic valve 6 that receives the output from the control unit 5 is opened and the cleaning water is discharged from the water supply nozzle 2.

The human body detector 4 is the urinal body 1
It is attached to the. The human body detector 4 is shown in FIG.
As shown in FIG. 3, the storage case 7 is arranged so as to penetrate through the opening 8 provided in the bowl surface 3, and protrudes to the peripheral edge of the translucent spherical lens 9 in the front portion of the storage case 7. The flange portion 10 is locked to the front surface side of the bowl surface 3, and the nut 12 is screwed onto the outer screw portion 11 provided at the rear portion of the storage case 7 from the back side of the bowl surface 3, whereby the bowl surface 3 The storage case 7 is integrally assembled to the opening 8.

The spherical lens 9 has a spring 13
Thus, the O-ring 14 is pushed forward and is inserted between the spherical lens 9 and the storage case 7 to form a waterproof structure.

A circuit board 15 is provided inside the spherical lens 9.
The light projecting element 16 mounted on the substrate is housed and a wiring opening 18 for introducing the lead wire 17 is provided behind the circuit board 15.

Now, as shown in FIG. 3, when the light projecting direction A of the light emitted from the light projecting element 16 of the human body detector 4 is facing the front, the opposite wall 31 is in a detectable range. When this urinal is installed in a different place, the control unit 5 produces an output due to the light reflected by the wall 31, and the wash water is discharged.

In such a case, as shown in FIG. 4, by rotating the spherical lens 9, it is possible to change the direction of the projected light and prevent malfunction.

Further, since the spherical lens 9 can be operated from the front of the urinal to change the direction of the light projecting element 16, even after the construction, the urinal can be easily projected without removing the urinal. The direction of the optical element 16 can be changed.

Embodiment 2 FIGS. 1 and 5 to 7 show another embodiment of the present invention.

First, the overall structure will be described with reference to FIG. In the urinal body 1, the flush water is discharged from the water supply nozzle 2 over the entire bowl surface 3 so that the bowl surface 3
Is to be washed.

At the center of the bowl surface 3 from the upper end,
A human body detector 4 for detecting a human body is provided.

The human body detector 4 is provided with a light projecting element 16 that throws light toward the user's foot and a light receiving element (not shown) that receives the light reflected by the foot, and senses signals from the light receiving element. Based on this, the control unit 5 generates an output, and the electromagnetic valve 6 that receives the output from the control unit 5 is opened and the cleaning water is discharged from the water supply nozzle 2.

The human body detector 4 is the urinal body 1

An O-ring 14 is provided between the housing 4 and the storage case 7 to provide a waterproof structure.

Projection direction A of the projection element 16 of the human body detector 4
6 is slightly downward with respect to the bowl surface 3 as shown in FIG. 6A, and as shown in FIG. 6B with respect to the front direction of the urinal body 1 (left in the figure). ), The light projected from the light projecting element 16 is directed obliquely forward of the bowl surface 3. This is to prevent the direction of light projection from going through the user's inseam and to hit an open foot.

Now, as shown in FIG. 7, when there is an obstacle 30 such as a tree in the light projecting direction A of the light emitted from the light projecting element 16, the controller 5 outputs an output by the light reflected by the obstacle 30. The cleaning water is discharged. In order to prevent this malfunction, the light projecting direction A of the light projecting element 16 can be changed by rotating the cap-shaped holder 22 of the human body detector 4 from the front of the urinal body 1.

A slip packing 21 is provided behind the cap-shaped holder 22 so that the cap-shaped holder 22 can rotate smoothly.

Embodiment 3 FIG. 8 and FIG. 9 show still another embodiment of the present invention.
