Abstract

An integrated faucet filtration system comprising a faucet assembly; a filter assembly; a first T-connector; and a second T-connector; wherein, the faucet assembly comprises a body; a spout; a spray head; a multi-channel hose fluidly coupled to the spray head and disposed in the spout; and a valve cartridge configured to control flow of unfiltered water; the filter assembly comprises a water filter; an electronic actuator; and a solenoid valve; the first T-connecter comprises a first branch configured to receive unfiltered water from a water source; a second branch configured to deliver unfiltered water to the water filter; and a third branch configured to deliver unfiltered water to the valve cartridge; and the second T-connecter comprises a first branch configured to receive unfiltered water from the valve cartridge; a second branch configured to receive filtered water from the water filter; and a third branch configured to deliver the filtered and unfiltered water.

First claim

The invention claimed is:

1. An integrated faucet filtration system comprising
a faucet assembly;
a filter assembly;
a first T-connector; and
a second T-connector;
wherein,
the faucet assembly comprises
a faucet body having a base configured to be positioned on a deck;
a spout;
a spray head;
a multi-channel hose fluidly coupled to the spray head and disposed in the spout; and
a valve cartridge configured to control flow of unfiltered water;

the filter assembly comprises
a water filter configured to be accessed from above the deck;
an electronic actuator; and
a solenoid valve;

the first T-connecter comprises
a first branch configured to receive unfiltered water from a water source;
a second branch configured to deliver unfiltered water to the water filter; and
a third branch configured to deliver unfiltered water to the valve cartridge; and

the second T-connecter comprises
a first branch configured to receive unfiltered water from the valve cartridge;
a second branch configured to receive filtered water from the water filter; and
a third branch configured to deliver the filtered and unfiltered water from the first and second branches to different channels of the multi-channel hose; and

wherein,
the electronic actuator is in electrical communication with the solenoid valve;
the electronic actuator is configured to open and close the solenoid valve;
when the solenoid valve is open, the system is configured to deliver filtered water; and
the electronic actuator and the solenoid valve are in electrical communication via a wire disposed in the multi-channel hose.

2. The system according to claim 1 , wherein the system comprises a mechanical actuator configured to select a form of unfiltered water.

3. The system according to claim 1 , wherein the electronic actuator is configured to be manipulated a first time to open the solenoid valve to deliver filtered water, and to be manipulated a second time to close the solenoid valve to stop filtered water flow.

4. The system according to claim 1 , wherein the spray head is configured to be pulled away from and returned to the spout.

5. The system according to claim 1 , wherein the filter assembly comprises a manifold configured to receive unfiltered water from the first T-connector and to deliver filtered water to the second T-connector.

6. The system according to claim 1 , wherein the system comprises one or more indicator lights, the indicator lights configured to display a status of the water filter and/or of a battery.

7. The system according to claim 1 comprising a battery, wherein the battery is in electrical communication with the solenoid valve.

8. The system according to claim 1 , wherein the electronic actuator is positioned on the spray head.

9. The system according to claim 1 , wherein the valve cartridge is disposed in the faucet body and associated with a faucet handle, and wherein the valve cartridge is configured to deliver hot water, cold water, or a hot water/cold water mixture to the second T-connector, the valve cartridge configured to deliver only unfiltered water.

10. The system according to claim 1 , wherein the water filter is disposed in an insertion adapter comprising an O-ring.

11. The system according to claim 1 , wherein the filter assembly comprises a compression spring, wherein the spring is compressed under the water filter.

12. The system according to claim 1 , wherein the filter assembly comprises a manifold and the solenoid valve and the water filter are disposed in and/or coupled to the manifold.

13. The system according to claim 1 , wherein when the solenoid valve is closed, the water filter is not under water pressure.
