Two handle pull-out faucet
View Patent ↗A dual-handle control faucet that includes a pull-out head and a faucet base. The pull-out head is switchable between a first water discharge pattern and a second water discharge pattern. The pull-out head switches from the first water discharge pattern to the second water discharge pattern upon disengagement with the faucet base, which provides for hands-free switching between to two spray patterns.
1. A faucet comprising:
a pull-out head coupled to a faucet base by a hose, said pull-out head switchable between a first water discharge pattern and a second water discharge pattern, wherein said pull-out head switches from said first water discharge pattern to said second water discharge pattern in response to disengagement with said faucet base and wherein said first water discharge pattern includes a stream mode and said second water discharge pattern includes a spray mode.
2. The faucet of claim 1 , further comprises a hot water control and a cold water control are fluidly connected to one of a central body and an underbody assembly.
3. The faucet of claim 2 , wherein said hot water control includes an off position, an on position, and a plurality of positions between said off position and said on position.
4. The faucet of claim 2 , wherein said cold water control includes an off position, an on position, and a plurality of positions between said off position and said on position.
5. The faucet of claim 2 , wherein a hot water passage connects said hot water control to said central body, and wherein a cold water passage fluidly connects said cold water control to said central body.
6. A sink faucet comprising:
a faucet base adapted to be mounted on a sink deck, said faucet base including an underbody assembly having at least one supply port fluidly coupled to a mixing body through a supply valve and a spout;
a hose slidably positionable within said spout, said hose having a first end fluidly coupled to said mixing body; and
a pull-out head fluidly coupled to a second end of said hose, said pull-out head positionable in a stowed position to engage said spout such that a mode valve in said pull-out head operates in a stream mode through a stream port and switches to operating in a spray mode through a spray port in response to movement to an extended position.
7. The sink faucet of claim 6 wherein said faucet base further comprises a first supply port fluidly coupled to said mixing body through a first supply valve and a second supply port fluidly coupled to said mixing body through a second supply valve.
8. The sink faucet of claim 6 wherein said mode valve comprises a flow toggle coupled to said hose and a diverter slidably positionable relative to said flow toggle for switching said mode valve between said stream mode and said spray mode.
9. The sink faucet of claim 8 wherein said flow toggle has a radial flow duct formed therein and said diverter has a central aperture formed therein, said diverter being slidably positionable relative to said flow toggle between a first position wherein said radial flow duct is in fluid communication with said stream port and a second position wherein said radial flow duct is in fluid communication with said spray port.
10. The sink faucet of claim 9 further comprising a spring operably disposed in said pull-out head to impart a biasing force on said diverter toward said first position.
11. The sink faucet of claim 10 wherein said diverter has a sealing face formed thereon, said sealing face being in fluid communication with said radial flow duct when said mode valve is in said spray mode such that a fluid pressure exerted on said sealing face counteracts said biasing force to maintain said mode valve in said spray mode.
12. The sink faucet of claim 6 wherein said pull-out head further comprises:
a first flow path from said hose through said mode valve to an aerator centrally disposed in said pull-out head to provide said stream mode; and
a second flow path from said hose through said mode valve to a set of apertures disposed around said aerator to provide said spray mode.
13. The sink faucet of claim 12 wherein said mode valve comprises a flow toggle coupled to said hose and a diverter slidable with respect to said flow toggle, said diverter positionable in a first position to select said first flow path and a second position to select said second flow path.
14. The sink faucet of claim 13 wherein said flow toggle has a radial flow duct and said diverter has a central aperture formed therein, wherein a portion of said flow toggle is positioned below said central aperture such that said first flow path is defined from said radial flow duct to said stream port when said diverter is in said first position, and wherein said radial flow duct is positioned above said central aperture such that said second flow path is defined from said radial flow duct to said spray port when said diverter is in said second position.
15. The sink faucet of claim 14 further comprising a spring operably disposed in said pull-out head to impart a biasing force on said diverter toward said first position.
16. The sink faucet of claim 15 wherein said diverter has a sealing face formed there on said sealing face being in fluid communication with said radial flow duct when said diverter is in said second position such that a fluid pressure exerted on said sealing face counteracts said biasing force to maintain said mode valve in said spray mode.
