DETAILED DESCRIPTION OF THE DRAWINGS

The embodiments of the invention described herein are not intended to be exhaustive or to limit the invention to the precise forms disclosed. Rather, the embodiments selected 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 to FIG. 1, a diagrammatic representation of a water delivery system 100 is shown. Water delivery system 100 includes an upper portion 102 which is accessible to a user form above a sink deck 104 and a lower portion 106 which is generally inaccessible to a user from above sink deck 104. In one embodiment, upper portion 102 and lower portion 106 are both modular such that various components may be added to or subtracted from either upper portion 102 and lower portion 106.

Lower portion 106 includes a hot water inlet port 108 connected to a hot water supply 110 and a cold water inlet port 112 connected to a cold water supply 114. Lower portion 106 includes internal water conduits which permit fluid entering hot water inlet port 108 to ultimately mix with fluid entering cold water inlet port 112. In one embodiment, lower portion 106 includes a valve 116 which controls the amount of fluid from hot water supply 110 and the amount of fluid from cold water supply 114 that are mixed together. As explained herein the amount of fluid mixed together from hot water supply 110 and cold water supply 114 is determined based on one or more user inputs, such as desired fluid temperature, desired fluid flow rate, desired fluid volume, various task based inputs (such as vegetable washing, filling pots or glasses, rinsing plates, and/or washing hands), various recognized presentments (such as vegetables to wash, plates to wash, hands to wash, or other suitable presentments), and/or combinations thereof. Presentments correspond to the placement of an item proximate to a delivery end of the spout. As such, it is similar to hands-free operation except that controller 120 is able to distinguish between item types.

In one embodiment, the valve is a single electronically controlled mixing valve which is in fluid communication with both hot water supply 110 and cold water supply 114. Exemplary electronically controlled mixing valves are described in U.S. patent application Ser. No. 11/109,281, filed Apr. 19, 2005, titled “ELECTRONIC PROPORTIONING VALVE”, now U.S. Pat. No. 7,458,520, and U.S. Provisional Patent Application Ser. No. 60/758,373, filed Jan. 12, 2006, titled “ELECTRONIC MIXING VALVE”, published as WO 2007/082301, the disclosures of which are expressly incorporated by reference herein. In one embodiment, valve 116 is a mixing valve, such as mixing valve 900 illustrated in FIGS. 32-41F. In another embodiment, valve 116 includes multiple valves, such as one for the hot input and the one for the cold input.

In one embodiment, a diverter valve, such as diverter valve 133 (see FIG. 1A), controls when water from the mixing valve 116 is provided to the user. Diverter valve 133 may have three settings: off, path A (corresponding to an internal waterway that is in communication with a stream aerator to provide a stream configuration from spout 130), and path B (corresponding to an internal waterway that is in communication with a spray aerator to provide a spray configuration from spout 130). Further, diverter valve 133 may be used to regulate a flow rate of water delivery system 100. In a metering example, diverter valve 133 may provide a first gross flow rate until the desired quantity is approached, then provide a second fine flow rate, being less than the gross flow rate, until the desired quantity is achieved. The same metering example may be achieved with mixing valve 116 as well.

Lower portion 106 further includes a controller 120. Controller 120 includes software that controls the operation of the water delivery system 100. In one embodiment, controller 120 receives inputs from various user input devices and/or sensors and provides control signals for various components, such as valve 116.

A fluid conduit 122 is shown connecting upper portion 102 and lower portion 106. Fluid conduit 122 is in fluid communication with a first output 124 of valve 116 through a port 123 of lower portion 106. In one embodiment, valve 116 includes a second output 126 which is in fluid communication with upper portion 102 through a port 127 and a second fluid conduit 128.

Upper portion 102 includes a spout 130 which is in fluid communication with fluid conduit 122. Upper portion 102 may further include an accessory 132A which is in fluid communication with fluid conduit 122 and/or an accessory 132B which is in fluid communication with fluid conduit 128. Exemplary accessories include a container filling device and a coffee pot.

Upper portion 102 may further include a user input device 140. User input device 140 may be attached to spout 130 and/or accessory 132A or 132B. User input device 140, in one embodiment, includes a touch sensor whereby a user of water delivery system 100 may specify one or more parameters of the water to be delivered, such as temperature, pressure, quantity, and/or flow pattern characteristics. In one embodiment, user input device 140 includes task inputs, temperature slider controls, and flow rate slider controls. In another embodiment, user input device 140 includes one or more mechanical inputs, such as buttons, dials, and/or handles.

Upper portion 102 may further include one or more sensors 142. Sensors 142 may be used to monitor characteristics of the water, such as temperature, dispensed water volume, water quality, and flow rate, or environmental characteristics, such as a presentment, the presence of an infrared emitting or reflecting body, a tap sensor, mode selections, such as units, and other sensors. In one embodiment, sensors 142 may be included in lower portion 106. In one embodiment, upper portion 102 includes a display which provides an indication to the user of water characteristics, such as temperature, dispensed water volume, water quality, and flow rate, or environmental characteristics, such as a presentment, the presence of an infrared emitting or reflecting body, a tap sensor, and mode selections, such as units.

Described herein are various spouts, controllers, user input devices, and other components of a water delivery system. It should be assumed that the functionality of spout 130, controller 120, user input device 140 and water delivery system 100 apply to each of the disclosed spouts, controllers, user input devices, and other components of water delivery system and that the various features of each spout, controller, and other components of a water delivery system may be included as apart of any other spout, controller, user input device, or water delivery system.

Referring to FIGS. 13A-D, an exemplary lower portion 150 is shown. Referring to FIG. 13A, lower portion 150 includes an electronic mixing valve 152 in fluid communication with two input waterways 154 and 156 and an output waterway 158. Mixing valve 152 and waterways 154, 156, and 158 are contained within a housing 160 which includes a first port 162A1, a second port 162A2, and a third port 162B. Ports 162A1-C are in fluid communication with internal waterways 154, 156, and 158, respectively. An external fluid conduit 164A is coupled to first port 162A1 and is in fluid communication with a supply of hot water 110. An external fluid conduit 164B is coupled to second port 162A2 and is in fluid communication with a supply of cold water 114. In one embodiment, the hot supply 110 and the cold supply 114 are plumbing connections provided below the sink deck. An external fluid conduit 164C is coupled to third port 162B and is in fluid communication with spout 130.

Lower portion 150 further includes a controller 166. Controller 166 includes a processor 168 and associated memory 170. In one embodiment, memory 170 includes software that is executed by processor 168 in performing the functionality described herein. Processor receives power from a regulator circuit 172 which is coupled to an external power supply 174. In the illustrated embodiment, regulator circuit 172 also includes a backup battery for use in the case of power interruption from power supply 174. In one embodiment, memory 170 is provided on board microprocessor 168. In one embodiment, memory 170 is removable.

Controller 166 adjusts the parameters of electronic proportional valve 152 through a drive circuit 176 which drives one or more motors associated with valve 152 (such as motors 1072 and 1098 shown in FIG. 44). Controller 166 receives temperature and flow settings from one or more user input devices 140 and sets the parameters of valve 152 to reflect the temperature and flow settings. The arrangement shown in FIG. 13A is an open loop arrangement because the output of valve 152 is not monitored to ensure that the requested temperature and flow are being provided to spout 130.

Referring to FIG. 13B, an example of a closed loop arrangement of lower portion 150 is shown. As shown in FIG. 13B, a sensor 178 is positioned in, coupled to, or otherwise monitors internal waterway 158. Sensor 178 monitors the temperature of the water in internal waterway 158 and the flow rate of water in internal waterway 158. In one embodiment, sensor 178 is comprised of multiple sensors, such as a first sensor to measure the temperature of the water and a second sensor to measure the flow rate of the water. The closed-loop arrangement permits controller 166 to monitor the output of valve 152 and to prevent the temperature of the water becoming too high that it scalds a user. As such, the closed loop arrangement permits the inclusion of safe hot water delivery option. The closed loop arrangement also provides feedback to controller 166 which permits the delivery of the desired temperature and the desired flow rate regardless of variations in the temperatures and/or pressures of hot supply 110 and cold supply 114.

Additional sensor may provide input to controller 166. Exemplary sensors include position sensors on valve 152. The position sensors may be associated with a motor associated with valve 166, a gear associated with valve 166, and/or plates associated with valve 166. Based on the value of the position sensors, controller 166 is able to know the temperature and/or flow rate valve 152 is currently set for.

Controller 166 still receives temperature and flow settings from one or more user input devices 140 and sets the parameters of valve 152 to reflect the temperature and flow settings. In FIG. 13B, user input device 140 also includes one or more preset controls, such as hot only, cold only, and task based inputs. In the illustrated embodiment, the temperature, flow, and selection of preset controls is communicated from user input device 140 to controller 166 over a serial connection.

Instant Hot module 183, in one embodiment, is in fluid communication with filter 182 through a waterway 185A, such that the water provided by spout 131 is filtered water. Instant Hot module 183, in one embodiment, is in fluid communication with filter 182 through a waterway 185B.

Referring to FIG. 13F, another exemplary arrangement of components is provided. As mentioned above, the supply of hot water 110 and the supply of cold water 114 may be the plumbing connections under the sink deck. The supply of cold water 114 generally is plumbed from the water line 187 entering the facility, such as the house, and may pass through other components prior to reaching the plumbing connection 114, such as a water softener. The supply of hot water 110 generally is plumbed to a central water heater 189 which heats water provided from the water line 187 to an elevated temperature. In one embodiment, central water heater 189 has a storage tank holding hot water.

In one embodiment, electronic diverter 193 is positioned above the sink deck, such as inside spout 130 or in a pull-out portion of spout 130.

In one embodiment, an in-line heater 191 is in fluid communication with the supply of hot water 110 and valve 152. Exemplary in-line heaters 191 include a heating element positioned within a waterway or a small water tank with a heating element. In-line heater 191, in one embodiment, provides instant warm water to valve 152. An exemplary temperature for instant warm water is about 120° F. As is known it often takes a period of time before hot water from central water heater 189 to reach valve 152. In-line heater 191, in one embodiment, provides instant hot water to valve 152. An exemplary temperature for instant hot water is about 120° F., about 150° F., at least about 120° F., or in the range of about 120° F. to about 150° F. In one embodiment, an instant hot feature is added to a lavatory faucet and the temperature is about 120° F. The operation of in-line heater 191 is controlled by controller 166.

In one embodiment, as illustrated in FIG. 62, in-line heater is used by controller 166 to maintain the output temperatures to spout 130 at the desired temperature. Depending on hot water usage in the house, after a task is started the central water 189 may not be able to provide sufficient amounts of hot water thereby resulting in the output temperature dropping. For small drops in the output temperature the proportion of hot water and cold water passing through valve 152 may be adjusted. In one embodiment, controller 166 utilizes in-line heater 191 to initially heat the water as well. In one example, wherein the water has been shut-off for an extended period of time, the water in the hot water plumbing returns to ambient temperature and in-line heater 191 boosts the temperature of the water passing by it until hot water reaches valve 152 from the central water heater 189. In one embodiment, controller 166 monitors the output temperature of the water leaving valve 152 with a sensor and adjusts in-line heater 191 accordingly. In one embodiment, controller monitors the temperature of the water in the hot water plumbing prior to in-line heater 191 with a sensor and adjust in-line heater accordingly. In one embodiment, controller monitors the temperature of the water in the hot water plumbing after in-line heater 191 and prior to valve 152 with a sensor and adjust in-line heater accordingly. In one embodiment, in-line heater 191 may raise the temperature of the water from about 20 to about 30 degrees at a flow rate of about one gallon per minute. In one example, the water temperature is raised about 30° F. when the water is flowing at about 0.5 gallons per minute and in-line heater 191 is using 110 VAC. In one example, the water temperature is raised about 30° F. when the water is flowing at about 2 to 3 gallons per minute and in-line heater 191 is using 230 VAC. The use of valve 152 and in-line heater 191 may be used in other applications as well, including a side spray and a shower. In one embodiment, controller 120 is able to guarantee a given temperature by setting a maximum flow rate based on the characteristics of in-line heater 191. Controller 120 may control or limit the flow rate to achieve the appropriate temperature rise. For 110 VAC, a temperature rise of 30 F may be achieved for a flow rate of about 1.0 gpm. For higher temperature rises, the flow rate may be further reduced.

Referring to FIG. 62 an exemplary method 1320 is shown. The output temperature reaches the desired temperature, as represented by block 1322. Sensor 178 measures the temperature of the output water, as represented by block 1324. If the temperature of the output water is about equal to the desired temperature, as selected through an user input, then controller 166 prepares to take the next measurement of the output temperature, as represented by blocks 1326 and 1328. In one example, the preparation for the next measurement includes waiting until a preset timer has expired. If the temperature of the output water is less than the desired temperature then controller 166 activates in-line heater 191 and prepares for the next measurement, as represented by blocks 1330 and 1328. The in-line heater is used to maintain the output temperature at a desired temperature even if the central water heater 189 is unable to do so.

In still a further embodiment, end portion 670 of spout 650 is a pull-out wand member and the flow of water may be activated by simply pulling end portion 670 from the remainder of spout 650. In one embodiment, the movement of end portion 670 is detected with hall effect sensors as described in U.S. patent application Ser. No. 11/325,128, filed Jan. 4, 2006, titled “SPOUT ASSEMBLY FOR AN ELECTRONIC FAUCET”, now U.S. Pat. No. 7,997,301, U.S. patent application Ser. No. 11/325,284, filed Jan. 4, 2006, titled “SPOUT ASSEMBLY FOR AN ELECTRONIC FAUCET AND METHOD FOR PROVIDING STRAIN RELIEF OF A CABLE”, now U.S. Pat. No. 7,631,372, and U.S. patent application Ser. No. 11/700,556, filed Jan. 31, 2007, titled “PULL OUT WAND”, now U.S. Pat. No. 8,118,240, the disclosures of which are expressly incorporated by reference herein and is applicable to all the disclosed spouts, each of which may include a pull-out wand member.

In one embodiment, the hands free operation is activated with a wired or wireless proximity sensor that is positioned below an upper surface of sink deck 104. The proximity sensor detects the presence of a person adjacent the cabinet area of the sink in front of the faucet and activates the faucet similar to the hands free operation adjacent the spout described herein. In one embodiment the proximity sensor is an infrared sensor. In one embodiment, the proximity sensor is positioned near the floor to detect the presence of a user's feet. In one embodiment, the proximity sensor is positioned to detect the presence of a user's legs. In one embodiment, the proximity sensor is positioned to detect the presence of a user's torso. Controller 120 activates water delivery system 100 in response to the detection of the user's feet and/or deactivates water delivery system 100 in response to the absence of detection of the user's feet.

In addition to providing water at the root mode setting, controller 120 may provide water through spout 650 as various other settings based on user input. In the illustrated embodiment, a full cold user input 680 is provided as a tap region on a right side of end portion 670 of spout 650. Tapping input 680 indicates to controller 120 that full cold water is desired without requiring the user to change the root mode setting. An indicator light (not shown) beneath tap region 680 illuminates a periphery of region 680 to indicate that region 680 is activated. Flow from spout 650 may be initiated by any of the automatic manners discussed above, tapping region 668, hands free, or pulling out end portion 670 of spout 650.

In one embodiment, two timers are initiated by controller 120 in response to the activation of region 680. A first timer, designated a non-attendance timer, has a first predetermined time period wherein if the user has not commenced with dispensing water through one of the automatic manners within the predetermined time period controller 120 returns the setting to the root mode. Returning the setting to the root mode includes adjusting valve 116 to coincide with the root mode temperature and flow rate. One example, wherein the non-attendance timer may cause the return to the root mode is the situation wherein a user taps function region 680, then leaves to answer phone or door. A second timer, designated a non-irritating timer, has a second predetermined time period wherein if the user has not commenced with dispensing water through one of the automatic manners within the predetermined time period since a previous dispensing controller 120 returns the setting to the root mode. One example, wherein the non-irritating timer may cause the return to the root mode is the situation wherein a user taps function region 680, fills a first glass with cold water and subsequently presents a second glass for filling. If the second glass is presented within the second predetermined timeframe then the second glass also receives full cold water otherwise water at the root setting. The return to root mode may be considered as a safety feature. If the root mode corresponds to a warm setting, then a hot setting selected for a given task would return to a safer temperature after a period of time to prevent the inadvertent dispensing of hot water. In one embodiment, a root mode or other setting is associated with hands free activation of the spout, whereby water at that specific settings is dispensed for hands free activation.

A user may also initiate the dispensing of full cold water from spout 650 by simply holding their finger on region 680. Controller 120 recognizes the hold or grab versus the tap and dispenses water from spout 650. Once the user releases region 680 the non-irritating timer is commenced. At the timeout of the non-irritating timer (the same is applicable to the non-attendant timer) the peripheral illumination of region 680 is stopped indicating a return to root mode.

Further, in embodiments where a large portion or generally all of the spout is touch sensitive, controller 120 is able to distinguish between a touch and a grab. In one example, a tap is less about 350 milliseconds and a grab is greater than about 350 milliseconds. As grasping the spout to orient the spout will not cause the activation of water flow nor the cessation of water flow. In one embodiment, wherein the spout includes a pull-out wand portion, pulling out the wand although a grab will begin the flow of water. The detection of the pulling out of a wand portion is discussed herein. Further, the hands-free sensors will be disabled while the wand is pulled out.

In the illustrated embodiment, a hot user input 682 is provided as a tap region one of a left side (not shown) of end portion 670 of spout 650 or at a base of spout 650. Tapping input 682 indicates to controller 120 that full hot water is desired without requiring the user to change the root mode setting. An indicator light (not shown) beneath tap region 682 illuminates a periphery of region 682 to indicate that region 682 is activated. Flow from spout 650 may be initiated by any of the automatic manners discussed above, tapping region 668, hands free, or pulling out end portion 670 of spout 650.

In one embodiment, controller 120 sets an upper limit to the temperature of hot water dispensed to prevent scalding. In one example, the user presses an input, such as a button, at the base of the spout to activate the upper limit of the temperature of hot water. As such, higher temperature water may be dispensed when the button has not been depressed. When the button is pressed a red light is activated to illuminate the button.

In one embodiment, two timers, a non-attendance timer and a non-irritating timer, are initiated by controller 120 in response to the activation of region 682. These timers function the same as discussed above in connection with region 680. As with region 680, a user may also initiate the dispensing of full hot water from spout 650 by simply holding their finger on region 682. Controller 120 recognizes the hold versus the tap and dispenses water from spout 650. Once the user releases region 682 the non-irritating timer is commenced. At the timeout of the non-irritating timer (the same is applicable to the non-attendant timer) the peripheral illumination of region 682 is stopped indicating a return to root mode.

In the illustrated embodiment, a preset user input 684 is provided as a tap region on the front of end portion 670 below tap region 684. Tapping input 684 indicates to controller 120 to set valve 116 to a user preset temperature and flow rate. An indicator light (not shown) beneath tap region 684 illuminates a periphery of region 684 to indicate that region 684 is activated. Flow from spout 650 may be initiated by any of the automatic manners discussed above, tapping region 668, hands free, or pulling out end portion 670 of spout 650.

In one embodiment, two timers, a non-attendance timer and a non-irritating timer, are initiated by controller 120 in response to the activation of region 684. These timers function the same as discussed above in connection with region 680. As with region 680, a user may also initiate the dispensing of water at the preset condition from spout 650 by simply holding their finger on region 684. Controller 120 recognizes the hold versus the tap and dispenses water from spout 650. Once the user releases region 684 the non-irritating timer is commenced. At the timeout of the non-irritating timer (the same is applicable to the non-attendant timer) the peripheral illumination of region 684 is stopped indicating a return to root mode.

User preset 684 may be programmed by selecting the desired temperature and flow rate with joystick 656 and tapping region 684 three times. In response the peripheral light around region 684 will flicker three times to indicate setting has been accepted. In another embodiment, multiple user presets are similar to region 684 are provided.

In one embodiment, tapping on preset region 684 cycles the faucet through various preset modes of operation, such as vegetable washing. An associated display provides an indication of the current mode and/or water characteristic settings. Further, in an additional embodiment, portion 670 of spout 650 includes a plurality of sensors, such as infrared sensors, (not shown) on a side of portion 670. The sensors are capable of detecting the presence of a user's hand. In one example, the sensors are arranged vertically to detect a direction of travel of a hand, either upward or downward. In one embodiment, the user waves the hand in an upward fashion to indicate to controller 120 to increase the temperature of the water or another water characteristic and waves the hand in a downward fashion to indicate to controller 120 to decrease the temperature of the water or another water characteristic. In another embodiment, the user waves the hand in a first direction, such as upward, to initiate the flow of water and in a second direction, such as downward, to cease the flow of water.

Further, tapping of dial 691 toggles through the various unit options centiliters, liters, quarts, illustratively cups and ounces. The user also positions the selector dial 691 to provide the proper amount of the selected unit, such as two and one-half cups. The user may position the selector dial to select the proper amount prior to selecting the proper units. The dispensing of the precise amount of fluid may be the result of the automatic modes discussed above, such as hands-free and tapping region 668. Once the precise amount of water has been dispensed the non-irritating timer is commenced. At the timeout of the non-irritating timer (the same is applicable to the non-attendant timer) the illumination of the corresponding unit 694 and 696 is stopped indicating a return to root mode. In one embodiment, controller 120 adjusts the flow rate of the water based on the quantity of liquid to be dispensed. For example, controller 120 sets a higher flow rate when several quarts are to be dispensed, as opposed to when a single cup is to be dispensed. This ensures that large containers fill quickly and fluid does not splash out of small containers.

Referring to FIG. 27B, user input device 654 is shown further including a base portion 700 which is used to select specific volumes of water to be dispensed by spout 650. Base portion 700 includes an amount input 702, illustratively a dial 703 having a plurality of corresponding indicia 704.

In one embodiment, the system described in U.S. patent application Ser. No. 11/325,927, filed Jan. 5, 2006, titled “METHOD AND APPARATUS FOR DETERMINING WHEN HANDS ARE UNDER A FAUCET FOR LAVATORY APPLICATIONS”, now U.S. Pat. No. 7,472,433, the disclosure of which is expressly incorporated by reference herein, incorporates an additional criteria for the hands free activation. Once the hands free is activated, the more stringent activation criteria (e.g. stable signal) is disabled for a period of time, such as a 30 second time window. This has the effect of boosting performance by shortening hands free response time when objects are rapidly moving in and out of the water stream. After the 30 second window has expired the more stringent criteria will again applied with unstable signals to prevent false hands free activations. In one embodiment, the above features are incorporated into the hand free operation of water delivery system 100.

Referring to FIGS. 32-41F, an exemplary mixing valve 900 is shown. Referring to FIG. 32C and FIG. 32D, mixing valve 900 includes a valve body 902 which is positioned in a housing 904. Valve body includes two input conduits 906A (see FIG. 32B) and 906B (see FIG. 32B) which are connected to and in fluid communication with respective sources of water, such as hot water and cold water and an output conduit 908 which is in fluid communication with a conduit of fitting 910 and is ultimately provided to spout 130 or other water delivery device. Both inputs 906A and 906B and output 908 are provided on a first end 912 of mixing valve 900.

Water passing through inputs 906A and 906B are communicated to respective openings 914 (see FIG. 35 wherein valve member 916 is shown flipped to better illustrate openings 914) in static valve member 916. Water is then communicated through respective openings 920 (see FIG. 35) in temperature control valve member 918 and onto flow control valve member 928, if the respective openings 920 are in fluid communication with respective openings 926. As explained herein temperature control valve member 918 is rotatable is directions 922 and 924. Such rotation changes whether one or both of respective openings 920 are in fluid communication with respective openings 926 and the extent to which each of respective openings 920 are in fluid communication with respective openings 926.

Water is communicated from respective openings 920 to opening 926 in flow control valve member 928, if the respective openings 920 are in fluid communication with opening 926. Flow control valve member is translatable relative to temperature control valve member 918 in directions 930 and 932. Such translation changes whether openings 920 are in fluid communication with opening 926 and the extent to which openings 920 are in fluid communication with opening 926. Water is then communicated from opening 926 back through temperature control valve member 918 through opening 932, through opening 934 in static valve member 916, and onto output 908 in valve body 902.

Returning to FIGS. 32C and 32D, a mixing element 940 which is positioned in output 908 which spins relative to valve body 902 to mix the water passing through output 908. Static valve member 916 is positioned adjacent valve body 902. A seal is formed between valve member 916 and body 902 with spring loaded seals. Temperature control valve member 918 is positioned adjacent to static valve member 916 and is retained by a valve retainer 950. As shown in FIG. 35, valve retainer 950 includes a plurality of teeth 952 which are engaged by a gear 954 (see FIG. 32C) which is coupled to a shaft of a stepper motor 956 (see FIG. 32C). Valve retainer 950 and temperature control member 918 each include respective keyways 958 and 960 which receive a key member to prevent the relative rotation of temperature control member 918 and valve retainer 950.

Stepper motor 956 rotates gear 954 to impart a rotation of temperature control valve member 918 thereby adjusting the relative amounts of fluid entering from respective openings 920 that is passed onto opening 926 in flow control member 928. As such, assuming that respective opening are in communication with hot water and cold water respectively, then the rotation of temperature control valve member 918 adjusts the temperature of water presented to opening 926 in flow control valve member. Stepper motor 956 is controlled by controller 120. Other types of motors may be used in conjunction with position control.

In the illustrated embodiment, valve retainer 950 includes an opening 951. Opening 951 is aligned with an optical position sensor 953 when temperature control valve is in a default position. When in the default position light of an emitter of optical position sensor 953 passes through opening 951 to a detector of optical position sensor 953.

Flow control valve member 928 is positioned adjacent to temperature control valve member 918 and is retained with a second valve retainer 970. Second valve retainer 970 includes a recess 970 which receives flow control valve member 928. The relative position of flow control valve member 928 relative to second valve retainer is maintained through a coupler 976, illustratively a pin.

Second valve retainer 970 further includes a pair of guides 978, illustratively grooves, which interact with a pair of guides 980 on housing cover 982. Guides 978, 980 restrict the movement of valve retainer 970 and hence flow control valve member 928 to directions 930 and 932 shown in FIG. 35. Valve retainer 970 is coupled to a linear stepper motor 990 which moves valve retainer and hence flow control valve in directions 930 and 932. Stepper motor 990 is controlled by controller 120.

As discussed herein the movement of one of temperature control valve member 920 and flow control valve member 928 are independent of each other. As such, temperature and flow may be independently adjusted by adjusting the respective one of temperature control valve member 920 and flow control valve member 928.

In one embodiment, mixing valve 900 may be used with a conventional manual faucet and positioned above sink deck 104. In this embodiment, temperature control valve 920 is coupled to a manual input, such as a ring member, instead of a stepper motor. The ring member is accessible from an exterior of the faucet and may be rotated to rotate temperature control valve member 920 in directions 922 and 924. In one embodiment the ring member is the valve retainer for temperature control valve member 920. In one embodiment, a plurality of detents are provided to provide feedback to the operator of the position of temperature control valve member 920. Further, in this embodiment, flow control valve member 928 is coupled to a manual input, such as a slider or a lever, instead of stepper motor 990. The lever or slider moves flow control valve member in directions 930 and 932.

Referring to FIGS. 42-48 a mixing valve 1000 is shown. Referring to FIG. 44, mixing valve 1000 includes an upper valve body 1002 and a lower valve body 1004. Upper valve body 1002 includes two input conduits 1006A and 1006B which are connected to and in fluid communication with respective sources of water, such as hot water and cold water, and an output conduit 1008 which is in fluid communication with a conduit of fitting 1010 and is ultimately provided to spout 130. Both inputs 1006A and 1006B and output 1008 are provided on an upper portion of mixing valve 1000.

Water passing through inputs 1006A and 1006B are communicated to respective openings 1014 in surface 1015 (see 1014A for input 1006A in FIG. 44) and to respective opening 1016 in static valve member 1017. Water is then communicated through respective opening 1020 in temperature control valve member 1018. As shown in FIG. 46A, openings 1016A-B have a first perimeter 1056A-B at a top side 1051 of static valve member 1017 and a second perimeter 1058 A-B at a bottom side 1052 of static valve member 1017.

As explained herein temperature control valve member 1018 is rotatable is directions 1022 and 1024. Such rotation changes whether one or both of respective openings 1020 are in fluid communication with a recess 1026 (see FIG. 48) in flow control valve member 1028. Flow control valve member is translatable relative to temperature control valve member 1018 in directions 1030 and 1032. Such translation changes whether openings 1020 are in fluid communication with recess 1026 and the extent to which openings 1020 are in fluid communication with recess 1026. Water is then communicated from recess 1026 back through temperature control valve member 1018 through opening 1033, through opening 1034 in static valve member 1017, and onto output 1008 in upper valve body 1002.

Referring to FIGS. 44 and 45, a gasket 1040 is received in a recess in upper valve housing 1002. Gasket 1040 includes openings 1044A and 1044B which surround openings 1014A and 1014B of inputs 1006a and 1006B, respectively, and an opening 1046 which surrounds an opening 1048 of output 1008 in upper valve housing 1002. Static valve member 1017 is positioned adjacent gasket 1040. Static valve member 1017 includes a recess 1050 in a bottom surface 1052 that generally matches the shape of gasket 1040 and receives gasket 1040. Gasket 1040 provides a water tight seal between upper valve body 1002 and static valve member 1017. Static valve member 1017 includes three key features 1060 which interact with respective key features 1062 (one shown in FIGS. 44 and 45) to prevent static valve member 1017 from rotating relative to upper valve body 1002.

Temperature control valve member 1018 is positioned adjacent to static valve member 1017 and is retained by a valve retainer 1064. A water tight seal is formed between surface 1051 of static valve member 1017 and surface 1019 of temperature control valve member 1018. As shown in FIG. 43, valve retainer 1064 includes a plurality of teeth 1066 which are engaged by a gear 1068 which is coupled to a shaft 1070 of a stepper motor 1072. Stepper motor 1072 is controlled by controller 120. Temperature control valve member 1018 is held in place relative to valve retainer 1064 by a flange 1074 and a plurality of holders 1076 which snap into recesses 1078 in temperature control valve member 1018.

Valve retainer 1064 and temperature control valve member 1018 each include respective key members 1080 (see FIG. 45) and 1082. Key members 1080 and 1082 prevent the relative rotation of temperature control valve member 1018 and valve retainer 1064.

Stepper motor 1072 rotates valve retainer 1064 to impart a rotation of temperature control valve member 1018 thereby adjust an amount of overlap between each of openings 1016A and 1016B relative to recess 1026 in flow control valve member 1028. In one embodiment, when valve 1000 is in an off position, openings 1020A and 1020B are completely misaligned with recess 1026, when in a full hot position the opening 1020A and 1020B corresponding to the hot input alone is in fluid communication with recess 1026, and when in a full cold position the other opening 1020A and 1020B corresponding to the cold input alone is in fluid communication with recess 1026. Openings 1020A and 1020B have a respective first perimeter 1023A and 1023B at surface 1019 and a respective second perimeter 1025A and 1025B at surface 1021. In one embodiment, the off position is not controlled by the rotation of temperature control valve member 1018 or flow control valve member 1028. but rather by a solenoid valve placed between mixing valve 1000 and an outlet of spout 130.

As explained herein, flow control valve member 1028 is translatable relative to temperature control valve member 1018 to adjust the amount of overlap between openings 1020A and 1020B and recess 1026. Referring to FIG. 47A, a perimeter of recess 1026 is shown in phantom in a location corresponding to an off position because neither opening 1020A or 1020B is in fluid communication with recess 1026. As flow control valve member 1028 is translated in direction 1030 recess 1026 begins to overlap the portions of openings 1020A and 1020B which are located in region 1086 which corresponds to the lateral extent of recess 1026. As shown in FIG. 47A, a portion of both openings 1020A and 1020B reside in region 1086. Thus as recess 1026 is moved in direction 1030 a warm water is provided to output 1008. Further, it is easy to see how by rotating temperature control disk 1018 in one of directions 1022 or 1024 the proportion of overlap of both openings 1020A and 1020B is adjusted. Complete control over the temperature and flow rate of water being provided to output 1008 is controlled through the interface between temperature control valve member 1018 and flow control valve member 1028 and the relative locations of each.

Returning to FIG. 44, flow control valve member 1028 is positioned adjacent to temperature control valve member 1018 such that surface 1027 of flow control valve member 1028 and surface 1021 of temperature control valve member 1018 form a water tight seal. In one embodiment, each of static valve member 1017, temperature control valve member 1018, and flow control valve member 1028 are made of a ceramic composition.

Flow control valve member 1028 is retained in place with a second valve retainer 1090. Second valve retainer 1090 includes a recess 1092 which receives flow control valve member 1028. Second valve retainer 1090 further includes a pair of guides 1094, illustratively grooves, which interact with a pair of guides 1096 (one shown in FIG. 48) on lower valve body member 1004. Guides 1094, 1096 restrict the movement of valve retainer 1090 and hence flow control valve member 1028 to directions 1030 and 1032 shown in FIG. 48. The movement of flow control valve member 1028 in direction 1032 is limited by a stop 1100 provided on lower valve body member 1004. Valve retainer 1090 is coupled to a linear stepper motor 1098 which moves valve retainer 1090 and hence flow control valve 1028 in directions 1030 and 1032. Stepper motor 1098 is controlled by controller 120.

In one embodiment, mixing valve 1000 may be used with a conventional manual faucet and positioned above sink deck 104. In this embodiment, temperature control valve member 1018 is coupled to a manual input, such as a ring member, instead of a stepper motor. The ring member is accessible from an exterior of the faucet and may be rotated to rotate temperature control valve member 1018 in directions 1022 and 1024. In one embodiment the ring member is the valve retainer for temperature control valve member 1018. In one embodiment, a plurality of detents are provided to provide feedback to the operator of the position of temperature control valve member 1018. Further, in this embodiment, flow control valve member 1028 is coupled to a manual input, such as a slider or a lever, instead of stepper motor 1098. The lever or slider moves flow control valve member in directions 1030 and 1032.

Returning to FIGS. 44 and 45, a mixing element 1102 is positioned in fluid conduit 1104 of fitting 1010. Mixing element 1102 mixes the water passing through fluid conduit 1104. Further, a flow turbine 1106 spins as water flows past it and the spinning of flow turbine 1106 is detected by a hall effect sensor 1107 which provides an indication of the flow rate of the fluid to controller 120. Further, a temperature sensor 1108 is positioned in fluid conduit 1104 and provides an indication of the temperature of the fluid to controller 102. Also, included in fluid conduit 1104 are two check valves 1110A and 1110B which prevent water from reentering mixing valve 1000. In one embodiment, one or both of check valves 1110A and 1110B are positioned in spout 130 or a pull out wand portion of spout 130.

Referring to FIGS. 49 and 50, another exemplary mixing valve 1150 is shown. Mixing valve 1150 operates in a similar manner to mixing valve 1000, except for valve retainer 1090′ being coupled to a stepper motor 1152 through a first gear 1154 and a second gear 1156 instead of to linear stepper motor 1098. Valve retainer 1090′ includes teeth 1158 which engage gear 1156 and convert the rotational motion of gear 1156 into a linear motion in directions 1030 and 1032. Housing 1004′ is modified to support stepper motor 1152.

Referring to FIGS. 51-56, yet another exemplary mixing valve 1200 is shown. Mixing valve 1200 includes a similar lower housing 1202 as mixing valve 1100. Housing 1202 includes inputs 1204A and 1204B which are coupled to sources of water, such as a hot water source and a cold water source, and an output 1206. Housing 1202 includes a recess 1210 for receiving a gasket 1212. Gasket 1212, like gasket 1040, includes openings 1214A and 1214B to surround the openings of inputs 1204A and 1204B and opening 1216 to surround output 1206.

Water passing through inputs 1204A and 1204B are communicated to respective openings 1220A and 1220B in a static valve member 1222. Static valve member 1222 includes a recess 1224 to receive gasket 1212 and an opening 1226 which is in fluid communication with output 1206. Water is then communicated to a recess 1228 is a temperature and flow control valve member 1230. Temperature and flow control valve member 1230 is retained in a valve retainer 1236 and is rotatable in directions 1232 and 1234 due to a rotation of valve retainer 1236. Temperature and flow control valve member 1230 and valve retainer 1236 each include respective key members 1238 and 1240 which locate temperature and flow control valve member 1230 relative to valve retainer 1236 and prevent the rotation of temperature and flow control valve member 1230 relative to valve retainer 1236.

An upper housing 1243 is positioned adjacent to valve retainer 1236 and holds temperature and flow control valve member 1230 in a fluid tight relationship relative to static valve member 1222. Referring to FIG. 51, a gear 1241 of valve retainer 1236 is engaged with a first gear 1242 that is coupled to upper housing 1243 which is in turn engaged with a second gear 1244 that is coupled to a shaft 1246 of a stepper motor 1248. Motor 1248 rotates gear 1244, which in turn rotates gear 1242, which in turn rotates valve retainer 1236 and temperature and flow control valve member 1230.

Unlike mixing valves 1000 and 1100 both of which have generally infinite flow control due to the translation of flow control valve member 1028, mixing valve 1200 has a low flow setting and a high flow setting which is selected based on the angular orientation of recess 1028.

Referring to FIGS. 54-56, mixing valve 1200 is shown in an off configuration (FIG. 54) 1250, a low flow configuration (FIG. 55) 1252, and a high flow configuration (FIG. 56) 1254. Referring to FIG. 54, temperature and flow control valve member 1230 is shown in an off configuration and recess 1028 in temperature and flow control valve member 1230 is not in fluid communication with either of openings 1220A or 1220B in static valve member 1222. As such, water is not communicated from inputs 1204A and 1204B to output 1206 in configuration 1250.

Referring to FIG. 55, temperature and flow control valve member 1230 is shown in an low flow configuration 1252 and a first portion 1260 of recess 1028 in temperature and flow control valve member 1230 is in fluid communication with both of openings 1220A or 1220B in static valve member 1222 and in fluid communication with opening 1226 in static valve member 1222 which is in fluid communication with output 1206. As such, water is communicated from inputs 1204A and 1204B to output 1206 in configuration 1250. Temperature and flow control valve member 1230 is moved to configuration 1252 by rotating temperature and flow control valve member 1230 in direction 1234 from the off configuration 1250. As shown in FIG. 55, temperature and flow control valve member 1230 receives water from both openings 1220A and 1220B. Thus, providing a warm water mixture to output 1206. By rotating temperature and flow control valve member 1230 in direction 1234 a lesser amount of opening 1220B is in fluid communication with recess 1228. Assuming opening 1220A corresponds to cold water and opening 1220B corresponds to hot water, the water communicated to output 1208 would be colder than the configuration shown in FIG. 55. By rotating temperature and flow control valve member 1230 even further in direction 1234 opening 1220B is no longer in fluid communication with recess 1228. This would correspond to a full cold setting for the low flow configuration 1252. By rotating temperature and flow control valve member 1230 in direction 1232 a lesser amount of opening 1220A is in fluid communication with recess 1228. The water communicated to output 1208 would be hotter than the configuration shown in FIG. 55. By rotating temperature and flow control valve member 1230 even further in direction 1232 opening 1220A is no longer in fluid communication with recess 1228. This would correspond to a full hot setting for the low flow configuration 1252.

Referring to FIG. 56, temperature and flow control valve member 1230 is shown in an high flow configuration 1254 and a second portion 1262 of recess 1028 in temperature and flow control valve member 1230 is in fluid communication with both of openings 1220A or 1220B in static valve member 1222 and in fluid communication with opening 1226 in static valve member 1222 which is in fluid communication with output 1206. As such, water is communicated from inputs 1204A and 1204B to output 1206 in configuration 1250. Temperature and flow control valve member 1230 is moved to configuration 1254 by rotating temperature and flow control valve member 1230 in direction 1232 from the off configuration 1250. As shown in FIG. 56, temperature and flow control valve member 1230 receives water from both openings 1220A and 1220B. Thus, providing a warm water mixture to output 1206. By rotating temperature and flow control valve member 1230 in direction 1234 a lesser amount of opening 1220B is in fluid communication with recess 1228. The water communicated to output 1208 would be colder than the configuration shown in FIG. 56. By rotating temperature and flow control valve member 1230 even further in direction 1234 opening 1220B is no longer in fluid communication with recess 1228. This would correspond to a full cold setting for the high flow configuration 1254. By rotating temperature and flow control valve member 1230 in direction 1232 a lesser amount of opening 1220A is in fluid communication with recess 1228. The water communicated to output 1208 would be hotter than the configuration shown in FIG. 56. By rotating temperature and flow control valve member 1230 even further in direction 1232 opening 1220A is no longer in fluid communication with recess 1228. This would correspond to a full hot setting for the high flow configuration 1254.

As shown in FIGS. 55 and 56, first portion 1260 of recess 1228 overlaps less with openings 1220A and 1220B than second portion 1262 in the respective low full configuration 1252 and high flow configuration 1254. By having a greater overlap between second portion 1262 and openings 1220A and 1220B, the flow rate of high flow configuration 1254 is higher than the flow rate of low flow configuration 1252.

In one embodiment, mixing valve 1200 may be used with a conventional manual faucet and positioned above sink deck 104. In this embodiment, temperature and flow control valve member 1230 is coupled to a manual input, such as a ring member, instead of a stepper motor. The ring member is accessible from an exterior of the faucet and may be rotated to rotate temperature and flow control valve member 1230 in directions 1232 and 1234. In one embodiment the ring member is the valve retainer for temperature and flow control valve member 1230. In one embodiment, a plurality of detents are provided to provide feedback to the operator of the position of the off configuration 1250, the low flow configuration 1252, and the high flow configuration 1254.

Controller 120 includes software to determine the connections made to the inputs of mixing valves disclosed herein. Using mixing valve 1000 in FIGS. 42-48 as an example, controller 120 performs the following installation configuration method 1280. Each mixing valve includes one or more stop surfaces to limit the rotation of the rotatable valve member in each direction. (See rib 1065 on valve retainer 1064 in FIG. 44 which interacts with a feature, such as a channel, on the valve body to limit the rotation of temperature control valve member 1018.) One of the limits is intended to correspond to a full “hot” position and the other of the limits is intended to correspond to a full “cold” position.

Referring to FIG. 57, in the installation configuration method 1280 controller 120 moves temperature control valve member 1018 to a first limit position, as represented in block 1282, and measures the temperature of the water in output 1008 with temperature sensor 1108, as represented by block 1284. Controller 120 then moves temperature control valve member 1018 to a second limit position, as represented in block 1286, and measures the temperature of the water in output 1008 with temperature sensor 1108, as represented by block 1288. In one embodiment, controller 120 waits a first period of time before measuring to allow the water to reach a steady state temperature. Controller 120 then compares the first measured temperature to the second measured temperature, as represented by block 1290. If the first measured temperature is higher than the second measured temperature then the first limit position corresponds to a full hot position, as represented by block 1292. If not then the second limit position corresponds to a full hot position, as represented by block 1294. With the installation configuration method controller 120, an installer is free to hook a hot water source to either of inputs 1006A and 1006B and the cold water source to the other of inputs 1006A and 1006B and controller 120 will compensate for the choice made by the installer.

Although the invention has been described in detail with reference to certain preferred embodiments, variations and modifications exist within the spirit and scope of the invention as described and defined in the following claims.
