Adjustable temperature regulated faucet
A method adjusts a regulated temperature in a faucet that includes a spout, a faucet body, a hot water valve and a cold water valve. The method includes regulating a maximum water temperature of water provided to the spout using a thermostatic valve cartridge to add cold water that bypasses the cold water valve to the water provided to the spout as a function of water temperature inside the thermostatic valve cartridge. The thermostatic valve cartridge is affixed to the faucet body and external access to the thermostatic valve cartridge is inhibited by at least one element. The method also includes removing the at least one element to expose at least a portion of a thermostatic valve cartridge, and rotating a rotatable portion of the thermostatic valve cartridge to adjust the regulated maximum water temperature.
1. A faucet assembly, comprising
a faucet body having a top, the faucet body supporting a spout extending away from the top of the faucet body in an upward direction, a hot water valve, a cold water valve, and a thermostatic mixing valve cartridge, the thermostatic mixing valve cartridge comprising a housing including at least a first inlet configurable to receive water from a first source, an outlet in fluid connection with the first inlet, and a second inlet configurable to receive water from a second source, and a thermal motor disposed within the housing,
wherein the thermal motor is configured to impart linear force in a first axial direction, wherein the imparting of linear force in the first axial direction increases the flow of water from the second source to the outlet, the first axial direction extending downward from the top of the faucet body.
2. The faucet assembly of claim 1 , wherein the housing includes a housing body, a cap and a lower housing, wherein the housing body is coupled to and disposed between the cap and the lower housing, and wherein the lower housing is disposed below the housing body within the faucet body.
3. The faucet assembly of claim 2 , wherein the housing body includes the first inlet, the lower housing includes the second inlet, and the cap includes the outlet.
4. The faucet assembly of claim 2 wherein water from the first source and water from the second source pass through an interior of the housing.
5. The faucet assembly of claim 4 , wherein the faucet body includes a receptacle for receiving the housing.
6. The faucet assembly of claim 1 wherein water from the first source and water from the second source pass through an interior of the housing.
7. The faucet assembly of claim 6 , wherein the faucet body includes a receptacle for receiving the housing, wherein the faucet body further includes an enclosure having a top surface, a hot water valve receptacle, and a cold water valve receptacle, and wherein the receptacle, the hot water valve receptacle and the cold water valve receptacle define respective openings in the top surface.
8. The faucet assembly of claim 6 , wherein the faucet body includes at least a first chamber operably connecting the hot water valve to the first inlet, and a second chamber operably connected between the second inlet and a source of cold water that bypasses the cold water valve.
9. The faucet assembly of claim 8 , wherein the first chamber operably connects the cold water valve to the first inlet, such that the first inlet is configured to receive hot water and cold water mixed together.
10. The faucet assembly of claim 9 , wherein the outlet is in direct fluid communication with the spout.
11. The faucet assembly of claim 1 , wherein the thermostatic mixing valve cartridge further comprises a rotatable cap configured to adjust a regulated maximum water temperature of water provided to the outlet of the thermostatic mixing valve.
12. The faucet assembly of claim 11 , wherein the cap includes at least one slot for receiving a rotating tool.
13. A faucet assembly, comprising:
a spout,
a faucet body having a receptacle,
a hot water valve;
a cold water valve,
a thermostatic valve cartridge disposed in the receptacle, the thermostatic valve cartridge include a housing and a thermostatic valve, the thermostatic valve configured to regulate a maximum water temperature of water provided to the spout by adding cold water that bypasses the cold water valve to the water provided to the spout as a function of water temperature inside the housing, the thermostatic valve cartridge comprising a rotatable maximum water temperature adjuster having a tool receptacle for receiving a tool to facilitate rotation thereof.
14. The faucet assembly of claim 13 , wherein the rotatable maximum water temperature adjuster comprises a rotatable cap.
15. The faucet assembly of claim 1 , wherein the thermal motor is configured to impart linear force in the first axial direction with respect to axial ends of the thermostatic of mixing valve cartridge, and wherein imparting linear force in the first axial direction increases the flow of water from the second source to the outlet; and wherein the outlet is disposed on a first axial end of the thermostatic mixing valve cartridge.
16. The faucet assembly of claim 15 , wherein the outlet is axially facing.
17. The faucet assembly of claim 1 , wherein the thermostatic mixing valve cartridge is disposed within the faucet body.
18. The faucet assembly of claim 17 , wherein the faucet body includes a receptacle for axial insertion of the thermostatic mixing valve cartridge.
19. The faucet assembly of claim 13 wherein the faucet body further includes an enclosure having a first surface, a hot water valve receptacle, and a cold water valve receptacle, and wherein the receptacle, the hot water valve receptacle and the cold water valve receptacle define respective openings in the first surface.
