Abstract
An automated water control system for a shower or bath that provides means for automated controls that give the user management of both water temperature and water flow as well as historical statistics on consumption.
Claims3
A water management system for a bathroom, the water management system comprising:
- a hot water supply line connected to a hot water heater, said hot water supply line providing hot water;
- a cold water supply line providing cold water;
- said hot and cold water supply line converging at a mixer valve, said hot water supply line having a first solenoid valve and a first temperature sensor intermediate said mixer valve and said hot water heater, said cold water supply line having a temperature sensor prior to said mixer valve;
- a mixed water supply line exiting said mixer valve;
- said mixed water supply line connected to first and second outlet lines, said mixed water supply line having a first branch, said first branch terminating in a accumulator tank, said mixed water supply line have a flow meter sensor and a second temperature sensor intermediate said mixer valve and said first branch, said mixed water supply line having a second branch connected to said hot water heater and including a second solenoid valve and a pump, said mixed water supply line having a third solenoid valve and a restrictor valve intermediate said second branch and said first and second outlet lines;
- said first outlet line connected to a tub spout and having a solenoid valve;
- said second outlet line connected to a shower head;
- and
- a central processing unit connected to said pump, said sensors and said valves for controlling the flow and temperature of water exiting said shower head and said tub spout.
