Abstract
A mechanical filter switch for use with a faucet including a valve piston assembly received within a diverter body for controlling the flow of cold water to a water filter.
Claims40
A water diverter device comprising:
- a diverter body including a hot water chamber, a cold water chamber blocked from the hot water chamber, a hot water inlet in fluid communication with the hot water chamber, a hot water outlet in fluid communication with the hot water chamber, a cold water inlet in fluid communication with the cold water chamber, a cold water outlet in fluid communication with the cold water chamber, and a filter water port in fluid communication with the cold water chamber;
- a valve piston assembly including a hot water valve member and a cold water valve member, the hot water valve member received within the hot water chamber, and the cold water valve member received within the cold water chamber;
- an actuator operably coupled to the valve piston assembly;
- and
- a user interface operably coupled to the actuator, wherein input to the user interface causes the actuator to move the valve piston assembly.

A water diverter device comprising:
- a diverter body including a hot water inlet, a hot water outlet in selective fluid communication with the hot water inlet, a cold water inlet, a cold water outlet in selective fluid communication with the cold water inlet, and a filter water outlet in selective fluid communication with the cold water inlet;
- and
- a valve piston assembly including:
- a first position wherein the hot water inlet is in fluid communication with the hot water outlet, the cold water inlet is in fluid communication with the cold water outlet, and the cold water inlet is blocked from the filter water outlet, and
- a second position wherein the hot water inlet is blocked from the hot water outlet, the cold water inlet is blocked from the cold water outlet, and the cold water inlet is in fluid communication with the filter water outlet.

A faucet comprising:
- a delivery spout including a faucet outlet;
- a diverter body including a hot water inlet, a hot water outlet in selective fluid communication with the hot water inlet, a cold water inlet, a cold water outlet in selective fluid communication with the cold water inlet, and a filter water outlet in selective fluid communication with the cold water inlet;
- a valve piston assembly including:
- a first position wherein the hot water inlet is in fluid communication with the hot water outlet, the cold water inlet is in fluid communication with the cold water outlet, and the cold water inlet is blocked from the filter water outlet, and
- a second position wherein the hot water inlet is blocked from the hot water outlet, the cold water inlet is blocked from the cold water outlet, and the cold water inlet is in fluid communication with the filter water outlet;
- wherein the hot water outlet, the cold water outlet, and the filter water outlet are fluidly coupled to the faucet outlet;
- an actuator operably coupled to the valve piston assembly;
- a user interface operably coupled to the actuator wherein input to the user interface causes the actuator to move the valve piston assembly;
- and
- a water filter fluidly coupled between the filter water outlet and the faucet outlet.
