Valve body assembly with electronic switching
First Claim
Patent Images
1. A valve assembly for use with an electronic faucet, the valve assembly comprising:
- a valve housing having a cavity;
a magnetic field sensor supported by the valve housing;
a valve member disposed within the cavity and including a hot water inlet and a cold water inlet, the valve member configured to control the mixture and flow rate of water from the hot water inlet and the cold water inlet delivered to a mixed water outlet, the valve member further including a magnet, the valve member being movable between a first position relative to the sensor to generate a first signal, and a second position relative to the sensor to generate a second signal, wherein the magnet is positioned farther from the sensor when the valve member is in the second position than when the valve member is in the first position; and
wherein the sensor is in electrical communication with a controller configured to control operation of an actuator driven valve.

11. An electronic faucet assembly comprising:
-
a water inlet conduit; a delivery spout; a valve body in fluid communication with the water inlet conduit and the delivery spout; a manual valve member supported by the valve body and configured to move between an open position and a closed position for controlling fluid flow from the water inlet conduit to the delivery spout; a sensing element supported by the manual valve member and configured to move with the manual valve member; a position sensor located in spaced relation to the sensing element and configured to detect the relative position of the sensing element and in response thereto provide a signal indicative of the position of the manual valve member; an actuator driven valve in fluid communication with the manual valve member; a proximity sensor having a detection zone, the proximity sensor being configured to generate a proximity signal when the proximity sensor detects the presence of an object within the detection zone; and a controller in electrical communication with the position sensor, the actuator driven valve, and the proximity sensor, the controller being configured to deactivate the proximity sensor when the position sensor indicates that the manual valve member is in the closed position. - View Dependent Claims (12, 13, 14, 15, 16, 17)

29. A valve assembly for use with an electronic faucet, the valve assembly comprising:
-
a valve housing; a valve member received within the valve housing and configured to be fluidly coupled to a hot water source and a cold water source; a mixed water outlet in selective fluid communication with the hot water source and the cold water source; wherein the valve member is movable in a first direction to control the flow rate of water delivered to the mixed water outlet and movable in a second direction to control the temperature of water delivered to the mixed water outlet; a magnet supported for movement with the valve member; and a magnetic field sensor configured to generate a first signal when the valve member is in a first position relative to the sensor. - View Dependent Claims (30, 31, 32, 33)
