The valve unit 2 is arranged so that the opening direction of the water inlet 21 is inclined at 45 degrees with respect to the horizontal.

On the other hand, the rear end of a water discharge pipe 17 made of resin is connected to the water outlet 2o of the valve unit 2. The front end of the water discharge pipe 17 serves as a water discharge port 18, which faces outward from the tip of the case 4 downward. Note that the front part of the water discharge pipe 17 is formed into a bellows that can be bent freely for positioning.

On the other hand, the connection vibe 3 is connected to the water inlet 21 of the valve unit 2.
Connect the water outlet 3o. The water inlet side of the connection vibrator 3 constitutes a connection port 31 that connects to the connection end Po of the water pipe P.

The connection port 31 is formed into a cylindrical shape, has a threaded portion formed on its outer periphery, and protrudes to the outside through the hole 32 or 33 of the case 4.

On the other hand, the opening directions of the water outlet 3o and the connection port 31 in the connection vibrator 3 are formed so as to have an angular relationship of 45 degrees to each other. Further, an intermediate waterway I9 is provided in the intermediate portion from the connection port 31 to the water outlet 30, which is perpendicular to the opening direction of the water outlet 3o.
It is formed to have a smaller diameter than o to provide a buffer function to alleviate the water hammer phenomenon that occurs when the water flow is abruptly interrupted. Further, a drain plug 20 for preventing freezing is provided on the axis of the water outlet 30. The drain valve 20 opens and closes the air intake port 2I for draining water remaining inside the water channel.

On the other hand, a moving body detection sensor 23 is disposed behind the water outlet 18 and on the lower surface of the case 4. The sensor 23 includes a pair of ultrasonic speakers 24 and an ultrasonic microphone 25.

In this case, by setting the orientation of the speaker 24 and the microphone 25, the usage position of the water W falling from the water outlet I8 is set within the detection area as shown in FIG.
