A water delivery assembly comprising a water dispensing device; an actuation assembly; and a mixing assembly, wherein the actuation assembly is configured to be operated to control a volume and a temperature of water delivered from the water dispensing device, the actuation assembly comprises a magnetic sensor assembly, and the mixing assembly is configured to be positioned exterior to or removed from the water dispensing device, and to deliver mixed hot/cold water to the water dispensing device.

Description

Water Delivery Assembly with Magnetic Sensor
The application is directed to a water delivery assembly, for example a faucet assembly, comprising a magnetic sensor assembly.
Background
Conventional faucet assemblies, for instance kitchen faucets, typically have a single handle configured to adjust both water volume (water flow rate) and water temperature. A kitchen faucet handle is typically coupled to a mixing valve, through which hot and cold source water are mixed and then delivered to a faucet spray head. Faucet design is limited as a faucet body houses a handle actuator associated with a mixing valve, among other components. Further, such manual handles are limited towards setting a desired water volume and temperature. Desired are faucet assemblies where for example a mixing valve and/or a handle may be positioned exterior to a faucet body, thereby providing a much greater freedom towards a faucet design. Also desired are handle actuators capable of providing a greater precision towards delivering a desired water volume and water temperature.
Summary
Accordingly, disclosed is a water delivery assembly comprising a water dispensing device; an actuation assembly; and a mixing assembly, wherein the actuation assembly is configured to be operated to control a volume and a temperature of water delivered from the water dispensing device, the actuation assembly comprises a magnetic sensor assembly, and the mixing assembly is configured to be positioned exterior to or removed from the water dispensing device, and to deliver mixed hot/cold water to the water dispensing device.
In some embodiments, a water delivery assembly may comprise a kitchen faucet, a bath faucet, a shower head, a tub spout, and the like. A mixing assembly may be configured to be positioned exterior to, or remote from, a water delivery assembly, for instance under a countertop, in a cabinet, behind a wall, etc. An actuation assembly may be positioned at or near a water delivery assembly, for instance coupled to a kitchen faucet body as in a conventional kitchen faucet, or in a shower stall. An actuation assembly may also be positioned exterior to or remote from a water delivery assembly, for instance on a countertop nearby a faucet, on a backsplash, or outside a shower stall on a bathroom wall.
A present mixing assembly and magnetic sensing assembly provides a high degree of freedom in design of water delivery assemblies, and also provides a high degree of precision towards providing a desired water temperature and flow rate.

Mixing assemblies 100 and 125 are configured to be positioned at an exterior of a faucet body, for example below/under a deck surface onto which a faucet is to be installed, or another “remote” location. Mixing assemblies 100 and 125 comprise housing 104, configured to house a water mixing valve or mixing valves. Assemblies 100 and 125 as shown also comprise first inlet water conduit 101 and second inlet water conduit 102, configured to couple to a hot source water line and a cold source water line, respectively (or vice-versa), and configured to deliver hot source water and cold source water to a mixing valve or valves. A mixing valve or mixing valves positioned at a housing interior space are configured to provide a mixture of hot and cold water, and to direct the hot/cold water mixture through mixing assembly outlet 103 to a faucet. Extending through housing 104 are electrical ports 105, configured to couple to electric wires coupled to one or more of a power source, a presence sensor, or an actuation assembly. Electrical ports 105 may be coupled to a controller or printed circuit board positioned at an interior of housing 104. Mixing assembly 125 further comprises knob 106 (temperature knob), which may be employed to pre-set a temperature of water to be delivered to a faucet in an automatic mode.
