Automatic excess water flow saving system
View Patent ↗An automatic excess water flow saving system reduces the water loss by water outlets in houses and other water consuming installations. The system controls the water flow through an outlet by toggling the water flow rate. An actuator activates a timer which opens and closes a valve intermittently and continuously while a water outlet is open.
1. A system for automatically regulating water flow from at least one water outlet connected to a water supply line, comprising:
an actuator coupled to the water supply line, the actuator including an actuator body, a proximity switch target, and a proximity switch;
a valve coupled to the actuator; and
a timer, which upon activation, is configured to cause the valve to alternate continuously at a predetermined frequency between an open state that allows a full water flow and a bypass state that allows a reduced water flow;
wherein, in response to the water outlet being opened and providing continuous water flow,
the water flow automatically causes the actuator to activate the timer by biasing the actuator proximity switch target to move towards a sensing region and turn the actuator proximity switch on to activate the timer, and
the timer automatically causes the valve to alternate at the predetermined frequency between the open state and the bypass state, such that the continuous water flow provided by the water outlet alternatingly and continuously switches between the full water flow and the reduced water flow to produce a continuous, blended flow rate at the at least one water outlet, and
wherein, in response to the water outlet being closed, the full water flow and the reduced water flow terminate.
2. The system of claim 1 , wherein the valve is configured to be a normally closed, unenergized solenoid valve.
3. The system of claim 2 , wherein the solenoid valve comprises a bypass hole that enables the reduced water flow.
4. The system of claim 2 , wherein the timer is configured to continuously energize and de-energize the valve to alternate between the open state for full water flow and the bypass state for reduced water flow.
5. The system of claim 4 , wherein the predetermined frequency at which the timer continuously energizes and de-energizes the valve to alternate between the open and bypass states is adjustable.
6. The system of claim 1 , further comprising a water-tight enclosure box.
7. The system of claim 6 , wherein the actuator, the valve, and the timer is contained within the water-tight enclosure box.
8. The system of claim 1 , further comprising a cable to provide access to a power source for the valve and timer.
9. The system of claim 1 further including an actuator spring, such that when the water outlet is closed and there is no water flow, the proximity switch target is biased to be positioned outside of the sensing region by the actuator spring in an extended state.
10. The system of claim 1 further including an actuator spring, such that when the water outlet is open, the water flow automatically biases the proximity switch target to move within the sensing region by providing an urging force to compress the actuator spring.
11. The system of claim 1 , wherein the actuator body comprises a pipe tee.
12. A method of automatically regulating water flow from at least one water outlet connected to a water supply line, by employing an actuator that includes a proximity switch target and a proximity switch, the method comprising:
providing the actuator that includes a proximity switch target and a proximity switch;
providing a valve;
providing a timer, which upon activation, is configured to cause the valve to alternate continuously at a predetermined frequency between an open state that allows a full water flow and a bypass state that allows a reduced water flow;
coupling the actuator to the water supply line that is connected to the water outlet;
coupling the valve to the actuator; and
electrically connecting the timer to the actuator and valve,
wherein, in response to the water outlet being opened and providing continuous water flow,
the water flow automatically causes the actuator to activate the timer by biasing the actuator proximity switch target to move towards a sensing region and turn the actuator proximity switch on to activate the timer, and
the timer automatically causes the valve to alternate at the predetermined frequency between the open state and the bypass state, the continuous water flow provided by the water outlet alternatingly and continuously switches between the full water flow and the reduced water flow to produce a continuous, blended flow rate at the at least one water outlet, and
wherein, in response to the water outlet being closed, the full water flow and the reduced water flow terminate.
13. The method according to claim 12 wherein, when the water outlet is opened, the water flow automatically biases the proximity switch target to move within the sensing region by urging compression of an actuator spring.
14. The method according to claim 12 , wherein, when the water outlet is closed and there is no water flow, the proximity switch target is biased to be positioned outside of the sensing region by the actuator spring in an extended state.
15. The method according to claim 12 , wherein the predetermined frequency at which the timer causes the valve to alternate between open and bypass states is adjustable.
16. The method according to claim 12 , wherein the valve comprises a solenoid valve in which the timer is configured to continuously energize and de-energize the valve to alternate between the open state for full water flow and the bypass state for reduced water flow.
17. The method according to claim 16 , further comprising modifying the solenoid valve with a bypass hole that accommodates the reduced water flow.
