FIG. In the longitudinal cross-sectional view of FIG. 1, the water supply pipe 2 and the exhaust hole 17, which will be described later, are located on the same axis, but the exhaust hole 17 is actually unevenly located on the left side as shown in FIG. This is what we are doing.

The main body 1 of the urinal is a stall type that is placed and fixed on the floor, and its front surface is inclined toward the installation surface.A water supply pipe 2 is connected to the center of the back of the upper side of the main body 1 to supply flush water. A rim passageway 4 for supplying the ball portion 3 is formed around the entire circumference from the upper end to the lower end.

After the cleaning water from the water supply pipe 2 flows into the water supply chamber 5 provided at the back of the main body 1, a portion flows from the rim side communication hole 6 in the rim water passage 4 direction, and a plurality of rim water injections are provided in the rim water passage 4. It is supplied to the ball part 3 through the hole 7. In addition, the remaining washing water flows into the stagnation channel 9 from the stagnation side communication hole 8, forming a stagnation water flow path system in which washing water is supplied from the stagnation water injection hole 10 toward the ball part 3. There is.

After cleaning the ball portion 3, the cleaning water supplied from these two systems passes through a trap 11 provided at the bottom of the main body 1 and is discharged to a drain pipe (not shown).

Reference numeral 15 denotes an exhaust flow path formed on the back side of the front wall 1a located on the upper side of the main body 1, and surrounded by the rim passageway 4 on both left and right sides, and the water supply chamber 5 at the back, and the lower end thereof is surrounded by a ball. It is open in three directions.

This exhaust flow path 15 is located approximately at the center of the main body 1,
An exhaust chamber 16 formed at the back of the upper end of the main body 1 communicates with the ball portion 3. An exhaust hole 17 is provided at the back of the exhaust chamber 16 at a position biased to the left side, and an exhaust pipe 18 having an exhaust fan 19 in the middle is connected to this hole.

Furthermore, 20 is a photoelectric sensor arranged through a mounting hole in the front wall 1a of the main body 1, and 21 is a control unit for automatic cleaning and automatic deodorization arranged separately from the main body 1. Reference numeral 21 controls the operation of an electromagnetic flush valve 22 attached to the water supply pipe 2 and an exhaust fan 19, and controls these devices based on the output signal from the photoelectric sensor 20 to perform automatic cleaning and automatic deodorization.
