TOUCHLESS FAUCET ASSEMBLY

摘要

A faucet assembly (10) includes a base for mounting adjacent a basin of a sink and a spout (14) projecting upward and outward away from the base and terminating at a water outlet (22). A light emitter (30) is mounted to one section of the spout and emits a beam of light directed toward another section of the spout, where a light sensor (34) is installed, wherein the beam of light does not intersect a region beneath the outlet. The light sensor (34), mounted to the spout, produces a signal indicating whether the beam of light is striking the light sensor. A control circuit responds to the signal by opening a valve that thereby conveys water to the spout.
