Control system for water faucets

A system for controlling flow of hot and cold water, comprising:

• a water faucets for supplying hot and cold water, respectively;
• b inlet hot and cold water lines connected to the water faucets for supplying hot and cold water to the corresponding hot and cold water faucets;
• c sink means for collecting outlet water from the water faucets, the sink means being disposed underneath and adjacent to the water faucets, and the inlet water lines being disposed under the sink means;
• d a first drain line connected to, and downwardly from the sink means for draining water in the sink to sewage;
• e a second drain line connected to, and downwardly from the sink means for draining water therefrom, the first and second drain lines forming a connection therebetween;
• f a water reservoir for receiving water from the second drain line;
• g an overflow drain line from the water reservoir and connecting to sewage;
• h a by-pass valve mounted between the first and second drain lines in the connection therebetween and adapted to divert water from the first drain line to the second drain line, thereby draining to the water reservoir;
• i a temperature sensor mounted within the inlet hot water line;
• j a water volume meter mounted within the inlet cold water line and adapted to control the flow rate of the cold water;
• k on-off solenoid valves mounted within the inlet hot and cold water lines;
• l a microprocessor, including a programming and command keyboard input, and an electrically actuated control box connected thereto for controlling operation of the by-pass valve, water flow rates, water temperature, and the on-off solenoid valves which control hot and cold water flow, the control box being electrically connected to the microprocessor, by-pass valve, on-off solenoid valves, temperature sensor and water volume meter;
• m an on-off control switch connected to the microprocessor and positioned in close proximity to the sink, the control switch being adapted to turn on the microprocessor and control box, and thereby turn on the system when depressed by a user's body when the user is in close proximity to the sink, and to turn off the system when pressure of the user's body is removed from the vicinity of the sink and away from contact with the control switch;
• and,
• n solenoid actuatuable inlet valves mounted within the respective inlet hot and cold water lines for turning hot and cold water on and off.
