ABSTRACT:
An electronic water faucet is disclosed, including means for detecting the presence of an object near an outlet of said faucet and determining whether or not noise or reflected light is being sensed. The faucet includes a swivelable spout relative to a main body. Position sensing means for sensing the angular position of the spout are included. The angular positions which the spout can assume are designed to various zones, and those zones are programmed to be active or not active in an automatic mode of operation of the faucet. A rotary mixing valve for supplying and mixing hot and cold water using a cam and deformable seal is used to partially seal hot and cold water inlets.
