EXAMPLES The present invention will be described in detail below with reference to examples. Figure 1
The urinal of this embodiment is shown in FIG.
Is a wall-mounted type that has been commonly used. The urinal body 1 has a front surface 10 with a vertical surface and a bottom surface 11
The ball portion 9 is formed by bending downwardly, and the water discharge port 2 is provided on the front surface 10. Urinal body 1
A cover 7 having substantially the same shape as the outer surface of the lower part of the urinal body 1 is attached to the lower side of the urinal body 1, and the front 7a of the cover 7 allows the presence of a person at a position slightly displaced to the right (or left) from the center. A detection sensor 5 for detecting is provided.

FIG. 2 shows a side sectional view of the urinal. The water discharge port 2 is formed by a nozzle 13 and is projected into the ball portion 9 from an opening 12 formed in a front surface 10 of the ball portion 9. An upper end of a pipe 14 is connected to the nozzle 13, and a lower end of the pipe 14 is connected to a water stopper 16 via a valve 15 such as a solenoid valve, so that washing water is supplied from a water tank to the water stopper 16. It flows in and is supplied to the nozzle 13 from the valve 15 through the pipe 14. Valve 15,
The water stopper 16 is arranged below the urinal body 1 and in front of the wall surface 19. A drainage port 3 is formed on the bottom surface 11 of the ball portion 9, and a drainage pipe 4 is integrally connected to the drainage port 3.

The cover 7 has a front surface 7a, a side surface 7b, and a bottom surface 7c.
Is formed from the upper surface of the upper opening edge 17
Is provided so as to project upward. The cover 7 is this locking piece 1
It is detachably attached to the lower side of the urinal body 1 by elastically locking 7 to the peripheral edge of the lower surface opening of the urinal body 1, and the rear opening end of the cover 7 is in contact with the wall surface 19. In this way, the valve 15 and the water stopcock 16 are housed inside the cover 7. A control device 6 is fixedly and integrally attached to the bottom surface 7c of the cover 7 in front of the valve 15 and the water stopcock 16. The control device 6 is electrically connected to the detection sensor 5 and the valve 15 by a wiring 18. There is. The control device 6 has a built-in electric circuit and controls the valve 15 in response to a signal detected by the detection sensor 5 to discharge or stop the washing water from the nozzle 13. As shown in FIG. 3, the control device 6 is attached at a position displaced rightward from the position right below the drain pipe 4. Further, the valve 15 and the water stopcock 16 are also attached at positions displaced to the left from directly below the drain pipe 4.

In the case of the urinal as described above, the cover 7 is detachably attached to the lower side of the urinal body 1, and the detection sensor 5, the control device 6, the valve 15 and the water stopcock 1 are provided in the cover 7.
Since 6 has been stored, each of the above parts can be exposed by removing the cover 7 from the urinal body 1. Further, since the control device 6 is installed at a position displaced from directly below the drain pipe 4, it is possible to prevent the control device 6 from being directly exposed to water even if the drain pipe 4 is damaged and causes water leakage. it can. Further, since the valve 15 is also attached at a position displaced from directly under the drain pipe 4, it is possible to prevent water from splashing on the electric circuit portion of the valve 15 when the valve 15 is a solenoid valve.

4 and 5 show another embodiment, in which a cover 8 of this embodiment is provided with a case 8 having an upper surface 8a and a side surface 8b, the front and rear surfaces of which are open. A control device 6, a valve 15, and a water stopcock 16 are housed inside the case 8. In this embodiment, since the control device 6 is housed in the case 8, even if the control device 6 having a built-in electric circuit sensitive to water is arranged directly under the drain pipe 4, the case 8 can protect the control device from water. . Further, since the valve 15 is also housed in the case 8, when the valve 15 is a solenoid valve, it is possible to prevent water from splashing on the electric circuit portion of the valve 15.

FIG. 6 shows another embodiment, in which the detection sensor 5 is attached to the wall surface 19 below the cover 7.

[0016]

As described above, according to the present invention, the control device is housed in the urinal body and the cover detachably formed, and the cover and the control device are integrated, so that the cover is removed from the urinal body. As a result, the control device can be exposed to the outside, and maintenance and repair of the control device can be easily performed. Further, since the valve and the water stopcock are housed in the cover together with the control device, maintenance and repair of these connecting parts including the valve, the water stopcock and the control device can be easily performed.

Further, according to the present invention, since the detection sensor is arranged on the outer surface of the cover, it is possible to expose the back side of the detection sensor and the connecting portion between the control device and the detection sensor by removing the cover, which facilitates maintenance and repair. It can be done. Further, according to the present invention, since the control device is arranged at a position other than directly under the drain pipe, even if the drain pipe is damaged and water leakage occurs, it is possible to prevent the control device from being directly exposed to water. The electric circuit of can be protected.

In addition, according to the present invention, since the control device is housed in the case in the cover, the control device can be protected by the case even if the control device is arranged below the drain pipe.
Even if the drain pipe is damaged and water leaks, the control device can be prevented from being directly exposed to water, and the electric circuit of the control device can be protected. Further, in the present invention, since the detection sensor is arranged in a place other than the urinal body, the detection sensor can be attached to any place regardless of the position of the urinal body.
