To provide a sensor-type faucet that can solve the problem in which even if a sensor-type faucet is a non-contact sensor, the non-contact sensor detects a hand by emitting an invisible medium such as ultrasonic or infrared rays, which are invisible to the naked eye, to detect the hands, so the hand cannot be recognized as being in the detection position of the non-contact sensor, and for this reason, the sensor-type faucet, especially those used in washrooms or similar settings, stops discharging water when the hand is unconsciously displaced from a non-contact sensor's detection position during hand washing, even if the washing process has not been completed.SOLUTION: A light-emitting means for irradiating visible light is provided at the detection position of a non-contact sensor, and by maintaining a state where a hand is irradiated with visible light from the light-emitting means, the water discharge is prevented from being unintentionally stopped.SELECTED DRAWING: Figure 1
【課題】センサ式水栓であっても非接触センサは超音波式や赤外線式の、目視できない媒体を照射して手を検知しているので、手が非接触式センサの検知位置にあることを認識できない。そのため、特に洗面所などで使用されるセンサ式水栓では、手を洗浄中に、洗浄が終了していなくても非接触センサの検知位置から無意識に手がずれると水の吐出が停止してしまう。【解決手段】非接触センサの検知位置に可視光を照射する発光手段を設け、手に発光手段からの可視光が照射されている状態を保つことにより水の吐出が意図せず停止することを防止するようにした。【選択図】 図１
