Claims (3)

吐水口に至る吐水経路に設けられた弁装置と、
吐水口付近の所定のセンサーエリアをセンシングし、そのセンサーエリアに差し出された人の手等を感知している間第１出力を発生し続ける自動吐水用の第１感知部と、
この第１感知部とは異なるセンサーエリアをセンシングし、そのセンサーエリアに差し出された人の手等を感知するたびに第２出力を発生する連続吐水用の第２感知部と、
上記第１感知部からの第１出力を検知している間は上記弁装置を開にして吐水させ、上記第１感知部からの第１出力を検知していない間は上記弁装置を閉にして吐水を停止する自動吐水モードと、上記第２感知部からの第２出力を検知すると上記弁装置を開にし、次の第２感知部からの第２出力があるまで上記弁装置を継続して開にする連続吐水モードと、を生じさせる第１制御手段と、
上記自動吐水モードをオン又はオフに切り替える切替出力を発生する切替手段と、
上記自動吐水モードがオンであり且つ上記第１感知部からの第１出力を検知している間で上記弁装置が開となり吐水している状態において、上記第２感知部からの上記第２出力を検知すると、上記弁装置を閉弁すると共に上記自動吐水モードをオフにする第２制御手段と、を有することを特徴とする自動水栓。 A valve device provided in the water discharge path to the water outlet;
A first sensor for automatic water discharge that senses a predetermined sensor area in the vicinity of the spout and continuously generates a first output while sensing the hand of a person or the like that has been presented to the sensor area;
A second sensing unit for continuous water discharge that senses a sensor area different from the first sensing unit, and generates a second output each time a person's hand, etc., presented to the sensor area is sensed;
While the first output from the first sensing unit is detected, the valve device is opened to discharge water, and while the first output from the first sensing unit is not detected, the valve device is closed. When the automatic water discharge mode for stopping water discharge and the second output from the second sensing unit are detected, the valve device is opened, and the valve device is continued until there is a second output from the next second sensing unit. A first water discharge mode for opening the first control means,
Switching means for generating a switching output for switching the automatic water discharge mode on or off;
While the automatic water discharge mode is on and the first output from the first sensing unit is detected, the second output from the second sensing unit is in a state where the valve device is open and water is discharged. And a second control means for closing the valve device and turning off the automatic water discharge mode when the valve device is detected. さらに、上記自動吐水モードがオンであり且つ上記第１感知部からの第１出力を検知している間で上記弁装置が開となり吐水している状態において、上記切替手段による上記自動吐水モードをオフに切り替える切替出力を検知すると、上記第１感知部によるセンサーのセンシングを停止させる第３制御手段を有する請求項１に記載の自動水栓。   Further, in the state where the valve device is open and discharging water while the automatic water discharging mode is on and the first output from the first sensing unit is detected, the automatic water discharging mode by the switching means is changed. 2. The automatic faucet according to claim 1, further comprising a third control unit configured to stop sensing of the sensor by the first sensing unit when a switching output to be switched off is detected. さらに、上記自動吐水モードがオンであり且つ上記第１感知部からの第１出力を検知している間で上記弁装置が開となり吐水している状態において、上記第２感知部からの第２出力を検知した場合には、上記第２制御手段により上記弁装置が閉弁されると共に上記自動吐水モードがオフにされ、このときに上記第１感知部によるセンサーのセンシングを継続させ、その継続状態において上記第１感知部からの第１出力の発生を検知しなくなると、上記自動吐水モードをオンに復帰させ、次の上記第１感知部による第１出力を検知すると上記弁装置を開にして吐水させる第４制御手段を有する請求項１又は請求項２に記載の自動水栓。   Further, when the automatic water discharge mode is ON and the first output from the first sensor is detected, the valve device is opened and water is discharged, and the second sensor from the second sensor is discharged. When the output is detected, the valve device is closed by the second control means and the automatic water discharge mode is turned off. At this time, the sensor sensing by the first sensing unit is continued, and the continuation is continued. When the generation of the first output from the first sensing unit is no longer detected in the state, the automatic water discharge mode is turned on, and when the first output from the first sensing unit is detected, the valve device is opened. The automatic faucet according to claim 1, further comprising fourth control means for discharging water.
