Touchless control of electronic water faucets

摘要

Embodiments described herein provide touchless temperature and/or flow control for water faucets utilizing the movements of a user's hand toward or away from to a dispensing area of the faucet. One embodiment comprises a water faucet that provides touchless control of water dispensed by the water faucet. The water faucet comprises a controller and a spout head. The spout head includes a sensor electrically coupled to the controller that detects a movement of a user's hand toward or away from the spout head. The controller initiates dispensing of the water from the spout head at a pre-defined rate, and varies the flow rate based on the movement of the user's hand toward or away from the spout head.
