BACKGROUND AND SUMMARY OF THE INVENTION
The present invention relates generally to water delivery systems, such as faucets, and more particularly to user inputs for faucets.
Faucets have traditionally been controlled by a manual user input, such as a single handle which is coupled to a mixing valve to proportion the flow of hot and cold water to a delivery spout, or two handles which utilize two separate valves to control the flow of hot and cold water. Typically, a user operates either the single handle or the two handles to regulate the flow of hot water and cold water, and hence both the flow rate and the temperature of a mixed water. Additionally, electronic user interfaces are known to control actuation of one or more valves to control the flow of mixed water through a delivery spout.
According to an illustrative embodiment of the present disclosure, a water delivery system includes at least one valve in fluid communication with a cold water source and a hot water source, the at least one valve including at least one actuator. An outlet is in fluid communication with the at least one valve, and a controller is operably coupled to the at least one actuator. An electronic user interface includes a first touch slider user input operably coupled to the controller, wherein the controller is configured to control the at least one valve such that the at least one valve delivers a desired flow rate of water to the outlet based upon the first touch slider user input. A second touch slider user input is operably coupled to the controller, wherein the controller is configured to control the at least one valve such that the at least one valve delivers a desired temperature of water to the outlet based upon the second touch slider user input. An indicator is operably coupled to the controller and is configured to provide an indication of the desired flow rate of water and the desired temperature of water.
According to another illustrative embodiment of the present disclosure, an electronic user interface for a water delivery device includes a first user input to control the flow rate of water delivered to an outlet, and a second user input to control the temperature of water delivered to an outlet. An indicator includes a colored light source, wherein the light source changes the magnitude of light emitted based upon the flow rate selected by the first user input and the light source changes the color of light emitted depending upon the temperature selected by the second user input.
According to a further illustrative embodiment of the present disclosure, an apparatus for controlling the provision of water above a sink deck from a source of cold water and a source of hot water includes a mixing valve in fluid communication with the source of cold water and the source of hot water, the mixing valve being located beneath the sink deck. An electronic user interface is located above the sink deck, and a spout is in fluid communication with an outlet of the mixing valve. A controller is operably coupled to the electronic user interface and to the mixing valve, wherein the electronic user interface includes a first touch slider user input for setting a desired water temperature and a second touch slider user input for setting a desired flow rate. The electronic user interface further includes a plurality of preset task inputs, and an indicator configured to provide an indication of the desired water temperature and the desired flow rate.
Additional features and advantages of the present invention will become apparent to those skilled in the art upon consideration of the following detailed description of the illustrative embodiment exemplifying the best mode of carrying out the invention as presently perceived.

DETAILED DESCRIPTION OF THE DRAWINGS
The embodiments of the invention described herein are not intended to be exhaustive or to limit the invention to precise forms disclosed. Rather, the embodiments elected for description have been chosen to enable one skilled in the art to practice the invention. Although the disclosure is described in connection with water, it should be understood that additional types of fluids may be used.
Referring initially to FIG. 1, a diagrammatic representation of a water delivery device 10 is shown. In the illustrative embodiment, the water delivery device 10 is fluidly coupled to a hot water source 12 and a cold water source 14. The water delivery device 10 illustratively includes a delivery spout 16 coupled to and supported above a mounting deck 18. Illustrative mounting decks 18 include a countertop, a sink top, a tub, a wall, and other suitable mounting structures.
In one illustrative embodiment, the water delivery device 10 is a residential kitchen faucet and the mounting deck 18 is one of a countertop or sink. As shown in FIG. 2, the delivery spout 16 includes a base portion 20 and an outlet portion 22. Both the base portion 20 and the outlet portion 22 are tubular members defining a passageway extending therethrough for receiving at least one tubular waterway 24. The base portion 20 includes a coupler, such as a threaded nut 25 engaging a tubular mounting shank 26 for securing the delivery spout 16 to the mounting deck 18. The outlet portion 22 supports an outlet 28, illustratively in a spray head member 30 including a central output 32 and a second, surrounding output 34 (FIG. 4). In one illustrative embodiment, the outlet portion 22 may swivel or rotate relative to the base portion 20 about a swivel coupling 36. In a further illustrative embodiment, the outlet portion 22 may include a pull-out wand portion of the type disclosed in U.S. patent application Ser. No. 11/700,556, Publication No. 2007/0246564, titled “PULL-OUT WAND,” the disclosure of which has been expressly incorporated by reference herein.
Base portion 20 of the delivery spout 16 is coupled to the mounting deck 18, while the outlet portion 22 is supported by the base portion 20. In the illustrative embodiment, the waterway 24 extends through the delivery spout 16 and is in fluid communication with a mixing valve 38 (FIG. 1). The mixing valve 38 is in fluid communication with the hot water source 12 and the cold water source 14 through waterways 40 and 42, respectively. Based upon input provided by a user interface 50 to a controller 52, the mixing valve 38 regulates the temperature and/or flow rate of water supplied to the waterway 24 of delivery spout 16.
In the illustrative embodiment of FIG. 1, the mixing valve 38 provides water on/off control, water flow regulation, and water temperature regulation. In one illustrative embodiment, the mixing valve 38 is comprised of multiple valve members 54 coupled to at least one actuator 56 and which together provide on/off control, water flow regulation, and/or water temperature regulation. Exemplary valves are detailed in U.S. patent application Ser. No. 11/737,727, Publication No. 2007/0246550, titled “ELECTRONIC USER INTERFACE FOR ELECTRONIC MIXING OF WATER FOR RESIDENTIAL FAUCETS,” the disclosure of which has been expressly incorporated by reference herein. While the illustrated embodiment shows a single mixing valve 38, it should be appreciated that separate valves may be fluidly coupled to the hot water source 12 and the cold water source 14 to provide similar water on/off control, water flow regulation, and/or water temperature regulation. Illustrative valves are detailed in U.S. patent application Ser. No. 11/109,281, Publication No. 2006/0231638, titled “ELECTRONIC PROPORTIONING VALVE,” the disclosure of which is expressly incorporated by reference herein.
The mixing valve 38 and the controller 52 are illustratively positioned on opposite sides of the mounting deck 18 as the base portion 20 and the outlet portion 22 of the delivery spout 16. In one illustrative embodiment, both the mixing valve 38 and the controller 52 are positioned on the same side of mounting deck 18 as the base portion 20. In a further illustrative embodiment, one or both of the mixing valve 38 and the controller 52 are incorporated into one of the base portion 20 and the outlet portion 22 of the delivery spout 16. In another illustrative embodiment, the controller 52 includes a first controller positioned in the outlet portion 22 of the delivery spout 16 and a second controller positioned in one of the base portion 20 and on an opposite side of the mounting deck 18. The first controller positioned in the outlet portion 22 interfaces with sensors included in the outlet portion 22, such as a temperature input 72a, a flow rate input 72b and/or a proximity sensor 70 (FIG. 3). The second controller positioned in the base portion 20 or on the opposite side of the mounting deck 18 interfaces with the mixing valve 38. The first controller and the second controller may be in communication with each other through either a wired or wireless connection. In a wireless connection, such as radio frequency (RF), the outlet portion 22 includes a battery to power the first controller.
Illustratively, the user interface 50 indirectly interacts with the mixing valve 38, such as by providing one or more inputs to the controller 52. Referring to FIG. 3, a diagrammatic representation of an illustrative embodiment of the user interface 50 is shown in communication with the controller 52 for controlling mixing valve 38. The mixing valve 38 may be in fluid communication with a diverter valve 58 via the waterway 24. Illustratively, the waterway 24 may be made of a cross-linked polyethylene (PEX) material. However, the waterway 24 and any of the additional waterways disclosed herein may be made of other materials, including metals or polymers. For example, waterway 24 may be formed of a polyethylene (PE), polypropylene (PP) or polybutylene (PB). It is further envisioned that the waterway 24 and any of the additional waterways disclosed herein could be formed of cross-linked polyvinylchloride (PVCX) using silene free radical initiators, from cross-linked polyurethane, or cross-linked propylene (XLPP) using peroxide or silene free radical initiators.
The diverter valve 58 is in fluid communication with two waterways 60 and 62 which are in fluid communication with a first output 64 and a second output 66, respectively, defined by the central output 32 and the surrounding output 34 of the spray head member 30 (FIG. 4). In one illustrative embodiment, the first output 64 defined by the central output 32 is configured to provide water in a stream configuration and the second output 66 defined by the surrounding output 34 is configured to provide water in a spray configuration.
As is known in the art, a diverter valve diverts the flow of a fluid from one of a plurality of potential fluid outlets based upon the configuration of the valve. By adjusting the configuration of the valve, the fluid outlet to which fluid is provided may be selected. Illustratively, the diverter valve 58 is a manual diverter valve including a rocker or toggle switch 68 (FIG. 4) configured to switch between the waterways 60 and 62 and the first and second outputs 64 and 66, respectively, in response to manual input from a user. The manual diverter valve 58 may be replaced with an electronically controller diverter valve, typically including a solenoid valve.
With further reference to FIG. 3, the user interface 50 includes a plurality of sensors operably coupled to the controller 52, through either a wired or wireless connection. In one illustrative embodiment, one or more of the sensors provide an indication of the presence of an object, such as a user's hands or other presentments, in a detection zone. Further, in an illustrative embodiment, one or more of the sensors detect the presence of touch by a user.
In the illustrative embodiment of FIGS. 3 and 4, the sensors include proximity sensor 70 and a plurality of touch sensors 72a, 72b, 74, 76, and 78. The proximity sensor 70 may be of conventional design as including an IR emitter which emits IR energy into a detection zone 79 and an IR detector which receives reflected IR energy from the detection zone 79 (FIG. 2). When an object, such as a user's hands, is detected in the detection zone 79, due to the amount of IR energy received by the IR detector, the proximity sensor 70 provides an indication thereof to the controller 52. In one illustrative embodiment, the controller 52 monitors a voltage corresponding to the IR level detected by the IR detector to determine whether user's hands are present in the detection zone 79. In another illustrative embodiment, the proximity sensor 70 is a capacitive proximity sensor. In one example, the range of the capacitive proximity sensor (i.e. detection zone 79) is about three inches from the outlet 28.
As further detailed herein, each touch sensor 72, 74, 76, 78 monitors a region of the user interface 50 supported by the outlet portion 22 and provides an indication to the controller 52 of a user touching that region. In one illustrative embodiment, touch sensors 72, 74, 76, 78 are capacitive sensors wherein the controller 52 monitors each capacitive touch sensor 72, 74, 76, 78 to determine when the user touches the region corresponding to the respective touch sensor 72, 74, 76, 78.
Referring now to FIGS. 2 and 4, illustrative user interface 50 is shown supported by the outlet portion 22 of the delivery spout 16. The user interface 50 includes a housing 80 received within the outlet portion 22 and supporting a removable cover 82. A lower end of the cover 82 includes a pair of hooks 84 which are coupled to anchors or pegs 86 of the housing 80. A fastener, such as a screw 88, may be used to couple the upper end of the cover 82 to the housing 80. The proximity sensor 70 is illustratively oriented downwardly from the housing 80. The spray head member 30 is fluidly coupled to the waterway 24 and may be removably docked with the bottom of the housing 80 in instances where the spray head member 30 forms part of a pull-out wand of the outlet portion 22. The spray head member 30 may be secured in a docked position through various means, such as a magnet or a bayonet coupling.
In one illustrative embodiment, the housing 80 and cover 82 are made of non-metallic material. Such illustrative non-metallic materials include polymers, for example thermoplastic or thermoset materials, such as polyesters, melamine, melamine urea, melamine phenolic, and phenolic.
As noted above, the proximity sensor 70 monitors detection zone 79 positioned on or below the end face of the outlet portion 22 of delivery spout 16. In one illustrative embodiment, the proximity sensor 70 is oriented to monitor a different detection zone 79, such as forward of, or forward and downward of, the outlet portion 22.
With further reference to FIGS. 3 and 4, the user interface 50 includes a touch sensor assembly 71 having a plurality of touch sensors 72a 72b, 74, 76, 78. Touch sensors 72a, 72b are slide sensors which monitor the position of a user's finger along a corresponding region 92a, 92b of the cover 82, respectively. Touch sensors 74, 76, 78a, 78b, 78c, 78d illustratively monitor regions 94, 96, 98a, 98b, 98c, 98d of cover 82, respectively.
Regions 92a, 92b associated with sensors 72a, 72b extend between opposing lower and upper ends 100a, 100b and 102a, 102b, respectively. A plurality of segments 104, 106 extend between the ends 100a, 100b and 102a, 102b of the regions 92a, 92b, respectively. While ten different segments 104, 106 are illustrated in FIG. 4 for each region 92a, 92b, it should be appreciated that the number may vary depending upon the application of the respective sensors 72a, 72b. Moreover, in certain embodiments, the regions 92a, 92b may be continuously variable between lower and upper ends 100a, 100b, and 102a, 102b. 
A user may adjust the desired temperature by touching one of the segments 104 within region 92a associated with the sensor 72a. By touching a segment 104 closer to the lower end 100a, a lower temperature is selected, while touching a segment 104 closer to the upper end 102 selects a higher temperature. A user may simply touch a segment 104 of region 92a corresponding to the desired temperature, or may contact a different segment 104 and drag the finger to the segment 104 corresponding to the desired temperature.
A user may adjust the desired flow rate by touching one of the segments 106 within region 92b associated with the sensor 72b. By touching a segment 106 closer to the lower end 100b, a lower flow rate is selected. Similarly, by touching a segment 106 closer to the upper end 102b, a higher flow rate is selected. A user may simply touch a segment 106 of region 92b corresponding to the desired flow rate, or may contact a different segment 106 and drag the finger to the segment 106 corresponding to the desired flow rate. The selected temperature and flow rate from sensors 72a and 72b, respectively, are communicated to the controller 52 which adjusts mixing valve 38 to provide the desired temperature and flow rate.
Sensors 74, 76, and 78 illustratively have predefined functions defined by the controller 52. Illustratively, when a user touches the region 94 associated with sensor 74, the controller 52 either turns on (activates) or turns off (deactivates) the water flow through the outlet 28 by controlling mixing valve 38. Subsequent touches of region 94 successively deactivates and activates (i.e., toggles) the water flow through mixing valve 38. Further illustratively, when a user touches the region 96 associated with sensor 76, the controller 52 turns on (activates) and turns off (deactivates) the proximity sensor 70.
Sensors 78a, 78b, 78c, 78d and associated regions 98a, 98b, 98c, 98d define preset or task buttons that may permit a user to rapidly switch between different tasks, such as from a hot water task like washing pots and pans to a cold water task like obtaining drinking water. Illustratively, the user may make adjustments to the water characteristics defined by a preset by selecting a different temperature with region 92a and/or selecting a different flow rate with region 92b. In one illustrative embodiment, the task sensors 78a, 78b, 78c, 78d are adjustable by the user such that the user may provide customized characteristics for a given sensor 78a, 78b, 78c, 78d. 
In one illustrative embodiment, the cover 82 may include indicia (not shown) to indicate to a user the location of the touch regions 92a, 92b, 94, 96, 98a, 98b, 98c, 98d and a function associated with each corresponding sensor 72a, 72b, 74, 76, 78a, 78b, 78c, 78d. The function corresponds to the actions taken by the controller 52 based on the detection of the touch by the user. Examples of input indicia and the corresponding action taken by the controller relative to a mixing valve and/or diverter valve are provided in U.S. patent application Ser. No. 11/737,727, filed Apr. 18, 2007, titled “ELECTRONIC USER INTERFACE FOR ELECTRONIC MIXING OF WATER FOR RESIDENTIAL FAUCETS,” the disclosure of which has been expressly incorporated by reference herein.
As stated above, the sensors 72a, 72b are illustratively slide touch sensors. As shown in FIGS. 4 and 8, sensors 72a and 72b are both illustratively supported on a common base member 110. Touch sensor 72b is substantially the same as touch sensor 72a. As such, the following discussion relative to touch sensor 72a is equally applicable to touch sensor 72b. 
The base member 110 supporting sensors 72a and 72b is illustratively formed of an electrically insulating, flexible material, such as Mylar®. While the base member 110 in FIG. 4 is shown to be in a substantially planar configuration, upon assembly within the user interface 50, the base member 110 conforms to a non-linear profile similar to that shown in FIG. 8 by adhering to the curved inner surface 112 of the cover 82. The inner surface 112 illustratively follows the general curvature of the outer surface 114 of the cover 82 which, in turn, is configured to conform to the shape of the outlet portion 22 of the delivery spout 16. An adhesive member 116, such as a double-faced adhesive tape, is used to adhere the base member 110 to the inner surface 112 of the cover 82.
With reference to FIGS. 4 and 10, the touch sensor 72a includes a plurality of contacts 118 that define the segments 104 of region 92a. The contacts 118 are illustratively formed by an electrically conductive material, such as copper applied to an outer surface 120 of the base member 110. Each contact 118 is electrically separated from an adjacent contact by a boundary 122. The boundaries 122 are illustratively formed in a saw tooth pattern such that a touch by a user bridging adjacent contacts 118 may be proportioned between such adjacent contacts 118. Illustratively, circuitry of controller 52 interpreting input from the sensors 72a, 72b may be manufactured by Cypress of San Jose, Calif.
The sensors 74, 76, and 78 are also illustratively formed by an electrically conductive material, such as copper, applied to the outer surface 120 of the base member 110. With reference to FIG. 10, traces or connecting paths 124 are also illustratively formed of an electrically conductive material, such as copper, and are electrically coupled to the contacts 118 of sensors 72a, 72b, and the sensors 74, 76, 78a, 78b, 78c, 78d. More particularly, the traces 124 provide electrical communication between the sensors 72a, 72b, 74, 76, 78a, 78b, 78c, 78d and a connector 126. The connector 126 is illustratively electrically coupled to a receptacle 128 within the housing 80 of the user interface 50 which, in turn, is electrically coupled to the controller 52.
With reference to FIGS. 3 and 4, indicator 130 is also provided within the user interface 50. More particularly, the indicator 130 includes a plurality of light sources 132 and 134, illustratively light emitting diodes (LEDs), supported on a base member 136, illustratively a printed circuit board. The base member 136 may be formed of an electrically insulating, flexible material, such as Mylar®.
While the base member 136 in FIG. 4 is shown to be in a substantially planar configuration, upon assembly within the user interface 50, the base member 136 conforms to a non-linear profile similar to that shown in FIG. 9 by adhering to the curved inner surface 138 of the base member 110 of the touch sensor assembly 71. More particularly, an adhesive member 140, such as double-faced adhesive tape, is used to adhere the outer surface 142 of the base member 136 to the inner surface 138 of the base member 110. A connector 144 is illustratively in electrical communication with the light sources 132, 134. The connector 144 is configured to be electrically coupled to a receptacle 146 within the user interface 50 (FIG. 4) which, in turn, is electrically coupled to the controller 52.
In one illustrative embodiment, the light sources 132 and 134 are surface mount LEDs available from Liteon of Milpitas, Calif. The LEDs 132, 134 are illustratively received within a slot 148 formed within the base member 110 of the touch sensor assembly 71. A window 150 is formed within the cover 82 and extends between lower and upper ends 152 and 154. The window 150 permits light generated by the indicator 130 to be visible from the exterior of the cover 82. Illustratively, the indicator 130 indicates a selected parameter of one or both of the sensors 72a, 72b. In one illustrative embodiment, the indicator 130 displays a current value of the parameter controlled by the input to sensor 72a. In a further illustrative embodiment, the indicator 130 indicates a current value of the parameter controlled by sensor 72b. In yet another illustrative embodiment, as further detailed herein, the indicator 130 indicates current values of the parameters controlled by both sensors 72a and 72b. 
As shown in the illustrative embodiment of FIG. 4, the LEDs 132 are interspaced with the LEDs 134. Illustratively, LEDs 132 are configured to emit a blue color, while LEDs 134 are configured to emit a red color. By varying the number of blue LEDs 132 illuminated relative to the number of red LEDs 134 illuminated, the displayed color changes. As further detailed below, the ratio of LEDs 132 illuminated relative to LEDs 134 (i.e., color) indicates the value of the parameter (e.g. temperature) controlled by sensor 72a, while the total number of combined LEDs 132 and 134 illuminated (i.e., magnitude or light level) indicates the value of the parameter (e.g. flow rate) controlled by sensor 72b. 
While longitudinally-spaced apart blue and red LEDs 132 and 134 are illustrated, it should be appreciated that variations may be substituted therefor. For example, each blue LED 132 may be spaced laterally adjacent a red LED 134, wherein a plurality of these laterally spaced combinations of blue and red LEDs 132 and 134 are longitudinally spaced apart from each other. In yet another illustrative embodiment, separate blue and red LEDs 132 and 134 may be replaced by a plurality of bi-color LEDs.
In the illustrative embodiment as shown in FIGS. 5-7, the indicator 130 provides a combined indication of parameters (e.g. temperature and flow rate) controlled by both sensors 72a and 72b through user input to regions 92a and 92b, respectively. In the illustrative embodiment detailed herein, input to region 92a and first sensor 72a controls temperature, while input to region 92b and second sensor 72b controls flow rate.
A hot water, low flow condition is represented by the indicator 130 in FIG. 5. More particularly, a user contacts segment 104j of region 92a corresponding to contact 118j of sensor 72a, thereby instructing the controller 52 that the greatest value of the applicable parameter (i.e., temperature) is requested. When a user contacts segment 106a of region 92b corresponding to contact 118a of sensor 72b, the controller 52 is instructed that the lowest value of the applicable parameter (i.e., flow rate) is requested (represented by water stream 156 in FIG. 5). The controller 52 instructs the mixing valve 38 to operate at a hot water, low flow condition. This is indicated to the user by the controller 52 causing the indicator 130 to illuminate only red LEDs 132 with a low magnitude of light displayed. In other words the indicator 130 displays red LEDs with a low height level (i.e. close to lower end 152) within window 150.
A warm water, medium flow condition is represented by the indicator 130 in FIG. 6. More particularly, a user contacts segment 104e of region 92a corresponding to contact 118e of sensor 72, thereby instructing the controller 52 that a value of the applicable parameter (i.e. temperature) proportioned between ends 100a and 102a is requested. In this instance, contact 118e is the fifth contact from end 102a out of a total of ten contacts 118 such that the desired temperature is 50% of the maximum value of sensor 118j at end 100a. Similarly, the user contacts segment 106e of region 92b corresponding to contact 118e of sensor 72b, thereby instructing the controller 52 that a value of the applicable parameter (i.e., flow rate) proportioned between ends 100b and 102b is requested. Again, contact 118e is illustratively the fifth contact out of ten total contacts such that the desired flow rate is 50% of the maximum value of sensor 118j at end 100b (represented by water stream 158 in FIG. 6). The controller 52 instructs the mixing valve 38 to operate at this warm water, medium flow condition. This 50/50 hot/cold mixed water, 50% flow rate condition is indicated by indicator 130 by illuminating an equal ratio of blue LEDs 132 and red LEDs 134 (to display temperature as a purple color) and half of the total number of total LEDs 132 and 134 (to display half of the distance or height between the bottom and top 152 and 154 of the window 150).
A cold water, full flow condition is represented by the indicator 130 in FIG. 7. More particularly, a user contacts segment 104a of region 92a which corresponds to contact 118a of sensor 72a, thereby instructing the controller 52 that a maximum value of the applicable parameter (i.e., temperature) is desired. Similarly, the user contacts segment 106j of region 92b which corresponds to contact 118j of sensor 82b, thereby instructing the controller 52 that a maximum value of the applicable parameter (i.e., flow rate) is desired (represented by water stream 160 in FIG. 7). The controller 52 instructs the mixing valve 38 to operate at this cold water, full flow condition.
