Abstract:
An automatic control system for a faucet of a sink, comprising:a valve block adapted to be disposed beneath said sink, inside a cabinet frame having a pair of hinged doors mounted thereon, said valve block having a plurality of supply inlet ports adapted to communicate with hot and cold water supply lines, a plurality of supply outlet ports adapted to communicate with hot and cold water faucet connecting lines for delivering hot and cold water to the faucet of said sink, and a pair of solenoid valves connected in parallel for controlling the flow of water to said supply outlet ports, a first of said solenoid valves adapted to control hot water flow and a second of said solenoid valves adapted to control cold water flow, each of said solenoid valves adapted to electrically communicate with an electrical power supply;at least one switch adapted to selectively complete the connection between said electrical power supply and said solenoid valves, whereby, upon completion of said connection, said solenoid valves simultaneously open to allow the flow of water to the faucet, said at least one switch including a latching switch that, upon being activated a first time, maintains completion of the connection of said electrical power supply and said solenoid valves until the switch is reactivated;a second switch in connection with said solenoid valves and said electrical power supply, said second switch being a momentarily non-latching switch and being separated from said latching switch for separate activation;and each of said doors in communication with a respective one of said switches, whereby either of said switches is activated by applying pressure to an associated one of said doors.
