PROBLEM TO BE SOLVED: To provide an automatic faucet device that does not malfunction due to steam nor malfunction due to a false detection in a bottom portion of a sink or a bowl. SOLUTION: An automatic faucet device discharges or cuts off water according to a detection by an object detection sensor 2. The object detection sensor 2 detects the existence of an object in the area between a water discharge part 5 and a bottom portion 7 of a sink 6 or a bowl. A reflection sensor 21 and a triangulation distance measurement sensor 22 are equipped as the object detection sensor 2. Water is controlled to be discharged when a detection value of reflected light by the reflection sensor 21 exceeds a predetermined value and a detection distance detected by the triangulation distance measurement sensor 22 is shorter than a predetermined distance. Water is controlled to be cut off in other cases than above. COPYRIGHT: (C)2012,JPO&INPIT |
