Sensor assembly for faucet
First Claim
1. A sensor assembly for controlling a solenoid valve, the solenoid valve controlling a flow of water through a faucet, the faucet being spaced apart from the sensor assembly, the sensor assembly comprising:
- a shank passing through an aperture in a wall and terminating at a flange at a first end of the shank;
a head coupled to the shank, the head comprising;
a base having a first side configured to be supported by a first side of the wall and a second side configured to interface with a first side of the flange, the base comprising an opening and a hole configured to receive an at least partially-threaded portion of the shank, wherein the flange is entirely contained within the base;
a top portion opposite the base and comprising a transparent or translucent cover that covers the opening of the base; and
circuitry positioned between the transparent or translucent cover and a second side of the flange opposite the first side, the circuitry at least partially received within a recess in the shank and interfacing with the second side of the flange, the circuitry comprising;
a proximity sensor comprising;
a transmitter configured to project a beam into a detection zone on the first side of the wall through the transparent or translucent cover, the beam extending substantially normal to and away from the wall; and
a receiver configured to detect a reflection of the beam off of an object in the detection zone; and
processing electronics configured to cause the solenoid valve to open in response to the receiver detecting a first reflection from the object in the detection zone; and
a nut threadedly coupled to the shank and configured to be supported by a second side of the wall opposite the first side of the wall such that tightening the nut on the shank secures the head on the first side of the wall and secures the nut on the second side of the wall.

Abstract
A sensor assembly for controlling a solenoid valve, the solenoid valve controlling the flow of water through a faucet, is described. The sensor assembly includes a head including a bottom portion configured to be supported by a wall and a top portion. The sensor assembly also includes a proximity sensor including a transmitter and receiver. The transmitter projects a beam into a detection zone. The sensor assembly also includes processing electronics configured to cause the solenoid valve to open in response to a receiver detecting a reflection from an object in the detection zone.

11. A system for controlling a flow of water through a faucet that provides water to a sink, the sink having a basin and a rim, the rim defining at least one faucet hole for mounting the faucet to the rim and defining an accessory hole spaced apart from the at least one faucet hole, the faucet having an outlet for discharging water into the basin and having at least one mechanical valve for controlling a temperature and a volume of the flow of water when the water is flowing, the system comprising:
-
a solenoid valve fluidly interconnected between the at least one mechanical valve and the outlet; a shank passing through the accessory hole, the shank terminating on one end in a flange located on a first side of the rim, the flange having a first side and a second side, the first side configured to interface with a base of a head, the base comprising a hole and the base configured to be supported by the first side of the rim, wherein the flange is entirely contained within the base; a proximity sensor positioned on circuitry that interfaces with the second side of the flange and configured to detect an object in a detection zone above the base; and a nut threadedly coupled to the shank and configured to be supported by a second side of the rim opposite the first side of the rim such that tightening the nut on the shank secures the base on the first side of the rim and secures the nut on the second side of the rim; wherein the solenoid valve is configured to close in response to a first detection by the proximity sensor of an object in the detection zone. - View Dependent Claims (12, 13, 14)

15. A kit for retrofitting an existing faucet system from manual to touchless operation, the existing faucet system including a faucet having an outlet for discharging water from the faucet into a basin and having a mechanical valve fluidly coupled to the outlet for controlling a flow of water through the faucet, the mechanical valve configured to receive water from a water supply, the kit comprising:
-
a solenoid valve assembly having at least one solenoid valve, an inlet, and an outlet; a proximity sensor assembly configured to detect an object in a detection zone comprising; circuitry comprising a transmitter configured to project a beam into the detection zone on a first side of a wall, the beam extending substantially normal to and away from the wall; a head having a base having a first side configured to be supported by the first side of the wall and the base having a second side configured to interface with a first side of a flange of a shank, the base comprising a hole configured to receive a portion of the shank, wherein the shank terminates on one end at the flange, wherein the flange is entirely contained within the base, and wherein a second side of the flange interfaces with the circuitry within the base; and a nut threadedly coupled to the shank and configured to be supported by a second side of the wall opposite the first side of the wall such that tightening the nut on the shank secures the head on the first side of the wall and secures the nut on the second side of the wall; processing electronics configured to toggle the at least one solenoid valve between an open state and a closed state in response to the proximity sensor assembly detecting the object in the detection zone; and instructions for retrofitting the existing faucet system, the instructions comprising; fluidly decoupling the outlet of the faucet from the water supply; fluidly coupling the solenoid valve assembly to the mechanical valve; placing the object in the detection zone to cause the at least one solenoid valve to toggle between the open state and the closed state. - View Dependent Claims (16, 17, 18, 19)
