Automatic faucet and water discharging device

Abstract

An automatic faucet that is easy to use with a sensor window that can be easily cleaned and a sensor that is suppressed from falsely detecting water stream ejected from a water spout member. An automatic faucet, which has a water spout member and a sensor placed in a front end section of a water spout pipe and automatically ejects water from the spout member by the detection by the sensor. The water spout member and the sensor are axially inserted into the water spout pipe from the obliquely downward opening of the tip of the water spout pipe, and the sensor is disposed above the water spout member. The water spout member is disposed in a state where the front end face thereof is positioned to the inside of the water spout pipe than the front end face of the sensor.

1 . An automatic faucet, which is provided with a water spout member and a sensor in a front end section that is a tip section of a water spout pipe, and which discharges water from the water spout member due to a detection of a detection target using a sensor,
 wherein the water spout pipe has a shape, in which a portion of the front end side is directed forward and obliquely downward with respect to a user and an opening, which has an opening face intersecting with a pipe axis and forms a face facing obliquely downward, is formed on the front end face of the water spout pipe, and   wherein the water spout member and the sensor are inserted from the opening into the water spout pipe in a pipe axial direction, and the sensor is installed above the water spout member in a state where the front end face of the water spout member is positioned on the back-side of the water spout pipe than the front end face of the sensor.   
     
     
         2 . The automatic faucet according to  claim 1 ,
 wherein the water spout member is placed in the water spout pipe so that the front end face of the water spout member is positioned on the back-side than the front end face of the water spout pipe.   
     
     
         3 . An automatic faucet, which is provided with a light emitting section and a light receiving section of an optical sensor, and a water spout member in a front end section that is a tip section of a water spout pipe, and which automatically discharges water from a water spout due to a detection of a detection target using an optical sensor,
 wherein the water spout pipe has a shape, in which a portion of the front end side is directed forward and obliquely downward with respect to a user and an opening, which has an opening face intersecting with a pipe axis and forms a face facing obliquely downward, is formed on the front end face of the water spout pipe, and   wherein the light emitting section, the light receiving section and the water spout member are inserted from the opening into the inner section of the front end section of the water spout pipe in a pipe axial direction in a state of being held by the holding member, each of the light emitting section, the light receiving section and the water spout member is extended to forward and obliquely downward, the light emitting section and the light receiving section are positioned above the water spout member, and the water spout of the front end of the water spout member is mounted in a state of being positioned in back-side of the water spout pipe than the light emitting window of the light emitting section side and the light receiving window of the light receiving section side, and   wherein a lower section leading to the light emitting window of the front face of the holding member is a face having a shape, which shifts to the back-side of the water spout pipe, as separating from the light emitting window toward the water spout side.   
     
     
         4 . The automatic faucet according to  claim 3 ,
 wherein a lower section leading to the light receiving window of the front face of the holding member has a face having a shape which shifts to the back-side of the water spout pipe as separating from the light receiving window toward the water spout side and.   
     
     
         5 . The automatic faucet according to  claim 3 ,
 wherein the light emitting window and the light receiving window are positioned to be projected forward from the front face of the holding member.   
     
     
         6 . The automatic faucet according to  claim 3 ,
 wherein the light emitting section is configured by a tip section of the optical fiber on the light emitting side, and the light receiving section is configured by a tip section of the optical fiber on the light receiving side.
