[0003] This application claims priority to U.S. Provisional Patent Application Serial No. 62 / 589,540, filed November 21, 2017, the disclosure of which is expressly incorporated herein by reference. Technical Field

[0004] This disclosure generally relates to a fluid delivery device, and more specifically, to a faucet including a wireless control module that facilitates voice control operation of an electrically operable valve. Background Technology

[0005] Electronic faucets typically include a electrically operable valve coupled to an electronic controller for controlling the flow of fluid through the outlet. Some electronic faucets include a proximity sensor (such as an active infrared (“IR”) proximity detector or a capacitive proximity sensor) to control the operation of the electrically operable valve. This proximity sensor can be used to detect a user’s hand near the faucet and automatically begin the flow of fluid through the faucet in response to the detection of the user’s hand. Other electronic faucets may use touch sensors (such as capacitive touch sensors) to control the faucet. An illustrative electronic faucet is described in detail in U.S. Patent Application Publication No. 2016 / 0362877 by Thomas et al., the disclosure of which is expressly incorporated herein by reference.

[0006] Electronic faucets that can be controlled by voice commands are known in the art. Such voice-controlled faucets may include a microphone to receive sound input for controlling the operation of an electrically operable valve. Summary of the Invention

[0007] This disclosure relates to a module accessory that can be added to an existing electronic faucet to allow for wireless control of the faucet. Input for such wireless control can originate from a variety of devices, including, for example, voice recognition and conversion devices, dedicated remote user interfaces, and / or smartphones.

[0008] The illustrative wireless control module disclosed herein adds functionality to existing electronic faucets, such as hands-free operation and programmable control of water flow (e.g., a handwashing mode in which water flow is timed). The wireless control module may also include sensors to measure water parameters such as water temperature and / or flow rate. The use of these sensors allows for added functionality, such as removing cold water from hot water lines (heating), dispensing a predetermined amount of water, and / or monitoring water usage.

[0009] Since the illustrative wireless control module is a releasably connected accessory and is not integrated into the electronic faucet, it can be added only by consumers who wish to obtain the added functionality, without involving unnecessary complexity and without burdening the base cost of the electronic faucet.

[0010] According to an illustrative embodiment of this disclosure, an electronic faucet includes a nozzle, a fluid supply conduit supported by the nozzle, and a valve assembly. The valve assembly includes an electrically operable valve positioned to control the flow of fluid through the fluid supply conduit. A valve controller is operable to control the electrically operable valve. A wireless control module communicates with the valve controller. The wireless control module includes a receiver configured to transmit and / or receive wireless signals from a remote transmitter and communicate with the valve controller to control the operation of the electrically operable valve.

[0011] According to another illustrative embodiment of this disclosure, a wireless control module for an electronic faucet includes: a body defining a fluid passage extending between an inlet and an outlet; a receiver configured to receive wireless signals from a remote transmitter; and a wireless controller operatively coupled to the receiver. A cable is coupled to the receiver and communicates with a valve controller to control the operation of an electrically operable valve. A releasable connector is configured to connect the inlet of the fluid passage to the outlet of the electrically operable valve.

[0012] Additional features and advantages of the invention will become clear to those skilled in the art after considering the following detailed description of illustrative embodiments, which exemplify the best mode for carrying out the invention as now understood. Attached Figure Description

[0026] For the purpose of promoting an understanding of the principles of this disclosure, reference will now be made to embodiments illustrated in the accompanying drawings, which will be described herein. The embodiments disclosed herein are not intended to be exhaustive or to limit the invention to the precise forms disclosed. Rather, these embodiments were chosen and described so that their teachings can be used by others skilled in the art. Therefore, it is not intended to limit the scope of the claimed invention. The invention includes any changes and further modifications to the illustrated apparatus and described methods that would commonly conceive of those skilled in the art, as well as further applications of the principles of the invention.

[0027] First refer to Figure 1 Block diagrams of an electronic faucet 10 are shown according to some illustrative embodiments of this disclosure. For example, the electronic faucet 10 includes a nozzle 12 that supports a channel or water passage (e.g., a fluid conduit) for delivering a fluid such as water. In the illustrated embodiment, the channel of the nozzle 12 includes a fluid passage between a hot water source 16 and a cold water source 18 and a water outlet 19 of the nozzle 12. See, for example... Figure 1The passages are 28a, 28b, 28c, 28d, and 28e. The electronic faucet 10 illustratively includes an electrically operable valve (such as a solenoid valve 22) in fluid communication with a hot water source 16 and a cold water source 18. The solenoid valve 22 is illustratively controlled electronically by a valve controller 24. It should be noted that the controller 24 may be integrated with or separate from the solenoid valve 22.

[0028] In the illustrated embodiment, valve controller 24 is configured to open and close solenoid valve 22 to open and close the fluid flow to outlet 19 of nozzle 12. In another illustrative embodiment, valve controller 24 is further configured to proportionally control valve 22 to regulate the flow rate and / or temperature of the fluid flowing through nozzle 12 to outlet 19. In the illustrative embodiments described herein, solenoid valve 22 includes a pilot-operated solenoid valve, but another suitable electrically operable valve or actuator-driven valve, such as an electronic proportional valve (EPV), may also be provided.

[0029] In the illustrated embodiment, valve controller 24 controls solenoid valve 22 based on outputs from at least one activation sensor (such as a proximity sensor and / or touch sensor) to, for example, open and close the fluid flow through nozzle 12. In the illustrative embodiment, the activation sensor includes capacitive sensor 26 that communicates with valve controller 24 to provide a signal indicating that an object (e.g., a user's hand) has been detected on or near nozzle 12. Other suitable activation sensors may be provided for detecting objects near faucet 10. As shown, electrodes 25 of capacitive sensor 26 are coupled to nozzle 12 (or part of nozzle 12) to detect objects contacting nozzle 12. Electrodes 25 may be positioned in other suitable areas of faucet 10 to detect the presence of a user's hand.

[0030] In the illustrative embodiment, the capacitive sensor 26 and electrode 25 are used in at least one of a touch operation mode and a hands-free operation mode. In the hands-free operation mode, the capacitive sensor 26 and valve controller 24 detect the user's hand or other object in a detection area or detection zone near the nozzle 12. In one embodiment, the detection area includes the water flow and the area in the sink immediately adjacent to the water flow. Depending on the position and sensitivity of the capacitive sensor 26, the detection area may be extended to other areas. In the touch operation mode, the capacitive sensor 26 and valve controller 24 detect the user's hand or other object when it comes into contact with the surface of the nozzle 12. To open the electronic faucet 10 in either mode, the solenoid valve 22 is activated by the valve controller 24 to open and close the water flow when an object (e.g., the user's hand) is detected.

[0031] In some illustrative embodiments, by utilizing a capacitive sensor 26 to sense changes in capacitance, the valve controller 24 is configured to make logical decisions to control different operating modes of the faucet 10, such as switching between a manual operation mode and a hands-free operation mode, as described in U.S. Patent Nos. 7,537,023; 7,690,395; 7,150,293; 7,997,301; and PCT International Patent Application Publications WO 2008 / 094651 and WO 2009 / 075858, the disclosures of which are expressly incorporated herein by reference.

[0032] In one illustrative embodiment, manual adjustment of water temperature and flow rate can be provided after the solenoid valve 22 is opened by manipulating the manual valve handle 14. The handle 14 can be supported by a sleeve 15 supporting the nozzle 12. More specifically, the sleeve 15 is illustratively positioned between the nozzle 12 and the mounting platform 17 (e.g., a sink platform). In particular, the manual valve handle 14 can be used to manipulate a manual valve assembly 20 positioned in the passage of the nozzle 12 to regulate the temperature and / or flow rate of fluid from the hot water source 16 and the cold water source 18 to the solenoid valve 22. A separate manual valve handle 14 and associated manual valve assembly 20 can be provided for each of the hot water source 16 and the cold water source 18. Alternatively, the electronic faucet 10 is a fully automatic faucet requiring no manual control (i.e., without the manual valve assembly 20). An illustrative manual valve assembly 20 is described in detail in U.S. Patent No. 7,753,074, the disclosure of which is expressly incorporated herein by reference.

[0033] In an illustrative embodiment, the valve controller 24 may further control the valve assembly 20 electronically. Specifically, the valve assembly 20 may include an electronic proportional valve or mixing valve, which is regulated by the valve controller 24 to control the mixing of hot and cold water and thus control the temperature of the water flowing through the nozzle 12 to the outlet 19. This electronic mixing valve 20 may be a complement to or replacement for the solenoid valve 22. Alternatively, the mixing valve 20 (with or without the solenoid valve 22) may be replaced by separate hot and cold water proportional valves.

[0034] An exemplary electronically controlled mixing valve is described in U.S. Patent No. 7,458,520 and PCT International Patent Application Publication No. WO 2007 / 082301, the disclosure of which is expressly incorporated herein by reference. The amount of fluid flowing from hot water source 16 and cold water source 18 can be controlled by valve controller 24 based on one or more user inputs, such as desired fluid temperature, desired fluid flow rate, desired fluid volume, inputs based on various tasks, various approved demonstrations, and / or combinations thereof. For example, faucet 10 may include a temperature sensor (e.g., temperature sensor 54 described herein) in fluid communication with the output of a proportional valve to provide feedback to valve controller 24 for controlling the water temperature. In one embodiment, valve controller 24 is located via auxiliary port 56 described herein (… Figure 2 Control proportional valve.

[0035] In one illustrative embodiment, the faucet 10 includes one or more indicators 29 controlled by a valve controller 24 to provide visual or audio indications of the operating mode (e.g., hands-free mode and / or touch mode) and / or water temperature of the electronic faucet 10. Exemplary indicators 29 include light-emitting diodes (LEDs) or other light sources, or sound devices positioned near the faucet 10. Other exemplary indicators 29 include liquid crystal displays (LCDs) and magnetically latched mechanical indicators. In one embodiment, the indicator 29 is operable to indicate the operating mode and / or temperature of water flowing through the faucet 10 based on the selective illumination of different colored LEDs or a single multi-color LED.

[0036] In the illustrated embodiment, in addition to the electronic faucet 10, the valve controller 24 can also communicate with a remote device, illustratively an auxiliary device 30. An exemplary auxiliary device 30 may include, for example, another faucet nozzle 30a. Figure 2 Auxiliary equipment 30 may also include a waste disposal unit, a dishwasher, an instant heating device, a remote switch (e.g., a foot switch), or any other device associated with or near the plumbing equipment. As further described herein, auxiliary equipment 30b ( Figure 2 The device may include a wireless communication device (e.g., a wireless control module). The auxiliary device 30 may be positioned near the same sink as the nozzle 12. Alternatively, for example, the auxiliary device 30 may be positioned to be assigned to a different sink (such as another sink in a bathroom or kitchen, or another sink in another room).

[0037] As described in detail herein, valve controller 24 illustratively includes auxiliary port 56 (see Figure 2 and Figure 3This auxiliary port is used for transmission via electronic cable 55 ( Figure 3 The auxiliary device 30 can be remotely controlled and / or powered. The electronic cable 55 can be of a conventional design and illustratively includes a serial cable comprising opposite first end connectors 57a and second end connectors 57b, providing bidirectional communication, as further described herein. More than one auxiliary device 30a, 30b, etc., can be coupled to different auxiliary ports 56 via multiple electronic cables 55a, 55b. While the illustrative auxiliary device 30 can be entirely controlled by the valve controller 24, the device 30 may also include a separate controller (e.g., a microprocessor) for operating itself while receiving power and / or communication signals from the controller 24.

[0038] Further reference Figure 2 It showed Figure 1 A block diagram of an exemplary valve controller 24 is provided. The valve controller 24 illustratively includes a printed circuit board 40 and multiple circuit components mounted to the printed circuit board 40. Illustratively, a processor 42, a flow sensor 52, a temperature sensor 54, multiple auxiliary ports 56, and an optical connector 58 are coupled to the circuit board 40. A connector plug 46 is illustratively coupled to the circuit board 40 for coupling a power line from an external power source 21. In one illustrative embodiment, the power source 21 is a battery power source or another direct current (DC) power source connected at the connector plug 46. The internal or external memory 44 of the processor 42 may include software and / or firmware containing instructions executed by the processor 42 for controlling the solenoid valve 22, other components of the faucet 10, and other devices (e.g., auxiliary device 30). The processor 42 illustratively controls the solenoid valve 22 based on the outputs from the capacitive sensor 26, the flow sensor 52, and / or the temperature sensor 54.

[0039] The optical connector 58 is configured to route current to an optical device 59, such as an LED, to illuminate the optical device 59, for example. In one illustrative embodiment, the optical device 59 is of different colors, and the processor 42 selectively controls the optical device 59 to illuminate different colors based on the operating mode of the faucet 10 and / or the temperature of the water flowing through the faucet 10. An exemplary optical connector 58 includes an audio jack connector. In one embodiment, Figure 1 The indicator 29 includes Figure 2 The optical device 59. In an exemplary embodiment, the valve controller 24 also includes a power connector 48 for coupling the valve controller 24 to a wall socket or other building power source to supply power to the valve controller 24. The power connector 48 illustratively includes a rectifier to convert alternating current (AC) power into a DC power level suitable for the valve controller 24.

[0040] refer to Figures 3 to 5 An exemplary solenoid valve assembly 50, including a solenoid valve 22, is shown, which is in fluid communication and electrical communication with a wireless control module 200. Fluid enters the valve housing 70 of the solenoid valve assembly 50 via a fluid conduit 28c. Figure 4 ), and exits the valve housing 70 via fluid conduit 28d, then flows through the wireless control module 200 and via fluid conduit 28e ( Figure 1 The fluid conduits 28d and 28e may include a seal 31. Figure 3 These seals provide sealed connections to the mating parts of fluid conduit 28e and the fluid conduit of nozzle 12, respectively. Oscillating connectors or couplings 71a and 71b are illustratively pivotally supported to connect fluid conduit 28c to inlet pipe 73 from manual valve assembly 20 and fluid conduit 28d to body 202 of wireless control module 200.

[0041] The solenoid valve assembly 50 illustratively includes an outer housing 60 for enclosing and protecting the valve controller 24 and solenoid valve 22 located within the housing 60. The outer housing 60 is configured to enclose the valve housing 70 ( Figure 4 The outer housing 60 is slidable onto the top of the outer housing 60 and mounted to the base 61 of the component 50. A clip 72 on the opposite end of the base 61 is configured to engage the outer housing 60, but other suitable fasteners can also be used to attach the outer housing 60 to the base 61. The outer housing 60 includes an opening 62 for receiving a fluid conduit 28d. The outer housing 60 further includes an opening 64 providing passage to an auxiliary port 56, an opening 66 providing passage to a DC power connector 48, and an opening 68 providing passage to an optical connector 58.

[0042] like Figure 4 As shown, valve controller 24 is mounted to valve housing 70 of assembly 50. Power cable 74 routes power from power source 21 to valve controller 24 to power the electronic components of valve controller 24. Power cable 74 includes wires that are configured to couple to plug 46 of valve controller 24. Figure 5 The connector end 76 of the nozzle 12 is routed between the opposite connector end 78, which is configured to couple to the power supply 21. An additional cable 75 may be provided for routing sensor signals, such as from the capacitive sensor 26, to the valve controller 24. In the illustrative capacitive sensing embodiment, the contact clip 79 may be electrically coupled to the mounting handle of the nozzle 12.

[0043] like Figure 4As shown, the solenoid coil 80 of the solenoid valve 22 comprises a coil wire 82 wound on a spool 84. In the illustrated embodiment, the solenoid coil 80 is directly mounted to the circuit board 40. A U-shaped metal bracket 90 is sized to fit onto the solenoid coil 80. The metal bracket 90 serves as a component for routing the magnetic flux generated by the solenoid coil 80. Specifically, when the controller 24 energizes the solenoid coil 80, the bracket 90 provides a flow path for the generated magnetic flux. Additional details of the solenoid valve 22 are provided in U.S. Patent Application Publication No. 2016 / 0362877 by Thomas et al., the disclosure of which is expressly incorporated herein by reference.

[0044] Further reference Figure 4 Processor 42, plug 46, temperature sensor 54, port 56, DC connector 48, and optical connector 58 are illustratively mounted to printed circuit board 40. Port 56, DC connector 48, and optical connector 58 are illustratively mounted at the edge of circuit board 40 to align with openings 64, 66, and 68 of outer housing 60. Circuit board 40 includes other suitable electronics for controlling solenoid valve 22. Plug 46 illustratively includes electrical pins configured to receive connector end 76 of power cable 74.

[0045] Auxiliary port 56 is configured to receive connector cable 55, which is routed to auxiliary device 30. Figure 2 The auxiliary device 30b can communicate with and be powered by the valve controller 24. Illustratively, the auxiliary device 30b may include a wireless control module 200. The connector cable 55 includes a first end connector 57a that is releasably coupled to one of the auxiliary ports 56. Thus, a plug-and-play configuration is provided with one or more auxiliary ports 56 that facilitate rapid coupling and decoupling of secondary devices (e.g., auxiliary device 30) that can be controlled using the valve controller 24 of the faucet 10. In one illustrative embodiment, more than one auxiliary device 30 is coupled to the auxiliary port 56 and controlled by the valve controller 24.

[0046] Refer again Figure 2 The control and power management software / firmware of valve controller 24, along with control switches, are illustratively used to control the operation of auxiliary devices(s) 30. Auxiliary devices 30 may include, for example, a soap dispenser, another faucet, a beverage dispenser, a filtered water dispenser, a hot water dispenser, or another suitable dispensing device. Figure 2As shown, the auxiliary dispensing device 30a may include a nozzle 38 supporting a fluid supply conduit. The dispensing device 30a illustratively includes electronics 32 communicating with a valve controller 24, including an electrically operable valve 34, such as a solenoid valve or electronic proportional valve (EPV), positioned within the fluid supply conduit for controlling the flow of fluid through the nozzle 38. The electronics 32 are releasably coupled to an auxiliary port 56 via a quick-coupler cable 55a routed between the faucet 10 and the device 30a. In one embodiment, similar to the capacitive control of the faucet 10, the fluid flow through the auxiliary device 30a is controlled by a processor 42 based on serial communication received via port 56 from the auxiliary device 30 (e.g., from a sensor 36). As described further in detail herein, the auxiliary device 30a may also include a separate controller (not shown) communicating with the valve 34 and / or the sensor 36 to control the operation of the valve and / or the sensor.

[0047] Valve controller 24 illustratively draws power from power supply 21 ( Figure 2 Power received from the faucet 10 or DC connector 48 is routed via port 56 to the electronics 32 of the auxiliary device 30 to power the device 30. Therefore, in one illustrative embodiment, both the faucet 10 and the auxiliary device 30 operate under the same power supply as managed by the valve controller 24. The valve controller 24 is operable to receive input from the auxiliary device 30, process the input, and output electrical signals based on the received input for controlling the electronics 32 of the device 30 (e.g., a solenoid, motor, lamp, etc.). In one embodiment, the auxiliary device 30 includes at least one proximity sensor 36 (such as a capacitive or infrared sensor) operable to detect a user's hand on or near the device 30, as similarly described herein with respect to the capacitive sensor 26 of the electronic faucet 10. Alternatively, the auxiliary device 30 may include a switching device configured to instruct the valve controller 24 to activate the device 30 when a user actuates the switching device. The valve controller 24 can control the flow of fluid (e.g., water, soap, beverage, etc.) through the auxiliary device 30 based on signals received from the proximity sensor 36 or the switching device. The valve controller 24 can also be operated to power indicator lights (such as LEDs) on the auxiliary device 30 that correspond to various operating modes or states of the device 30.

[0048] Therefore, the auxiliary device 30 may include a passive electrical interface or a dumb electrical interface with limited or no active control, wherein the electronics 32 of the interface are remotely controlled by the valve controller 24 of the faucet 10 via an auxiliary port 56. In one illustrative embodiment, the circuitry of the auxiliary device 30 includes circuitry for connecting the device 30 to the valve controller 24, for detecting and sending an activation request to the valve controller 24, and for actuating the fluid valve based on control from the valve controller 24. In other illustrative embodiments, the auxiliary device 30 may include a controller (e.g., a microprocessor) for operating itself, wherein the auxiliary device 30 receives power and / or communication only from the controller 24.

[0049] In one illustrative example, auxiliary port 56 includes a multi-pin (e.g., 8-pin) registered jack (RJ) socket, but any suitable electrical connector can be used for port 56. In one illustrative embodiment, the multi-pin connections of auxiliary port 56 include a switching power supply, a ground line, a serial data transmission line, a serial data receive line, an interrupt line, a 3.3-volt power line, and a reset line. The switching power supply is connected to a battery voltage (e.g., power supply 21) to power the electronics of auxiliary device 30.

[0050] Temperature sensor 54 can be directly mounted (e.g., soldered) to circuit board 40. Thus, sensor 54 is illustratively positioned on the exterior of valve housing 70. In one illustrative embodiment, temperature sensor 54 comprises a surface-mount NTC thermistor soldered to circuit board 40, but other suitable temperature sensors may also be used. Heat transfer devices extend from temperature sensor 54 to the interior area of ​​valve housing 70 or water passage 130. Figure 5 The heat transfer device is operable to transfer heat from the fluid within the internal region 130 of the valve housing 70 to the temperature sensor 54, as described herein.

[0051] Illustratively, processor 42 is operable to control faucet 10 based on water temperature measured using temperature sensor 54. In one illustrative embodiment, processor 42 is operable to selectively control optical device 59. Figure 2The processor 42 illuminates different colored devices 59 to indicate water temperature to the user. For example, blue indicates cold water, red indicates hot water, and a hue between red and blue indicates a temperature between cold and hot. Alternatively, the processor 42 illustratively displays the water temperature digitally on a digital or analog display (e.g., the LCD display of indicator 29). In one illustrative embodiment, the valve controller 24 is programmed to automatically cut off the water flow, i.e., close the solenoid valve 22, when the detected water temperature exceeds a threshold temperature. An exemplary threshold temperature is approximately 120 degrees Fahrenheit, but other suitable thresholds may be set. In one embodiment, the controller 24 uses temperature information from sensor 54 to control an electrically operable mixing valve (e.g., valve 20) connected in series with solenoid valve 22. This mixing valve is controlled to proportionally mix water from heat source 16 and cold source 18 to achieve a desired temperature. The desired temperature may be selected by the user or may be predetermined and programmed in the memory of the processor 42. Thus, the temperature sensor 54 can be used to provide closed-loop temperature control of the water flowing through the faucet 10. Other suitable temperature-based controls may also be implemented.

[0052] refer to Figures 6 to 8 The illustrative wireless control module 200 includes a body or conduit 202, which includes a tube 204 defining a water or fluid channel 206 extending between an inlet 208 and an outlet 210. The body 202 may be formed of a polymer such as a glass fiber reinforced thermoplastic. A housing or cover 212 is attached to the body 202. More specifically, an end wall 214 of the body 202 is attached to an open end 216 of the housing 212. The housing 212 may be formed of a polymer such as polyoxymethylene. An inlet portion 218 of the tube 204 extends from the end wall 214 in a first direction, and an outlet portion 220 of the tube 204 extends from the end wall 214 in a second direction opposite to the first direction. A chamber 222 is defined within the housing 212 and receives a wireless controller 224. The outlet portion 220 of the tube 204 extends through the chamber 222 and extends out of the housing 212 via an opening 226 in the end wall 228.

[0053] Inlet 208 is fluidly connected to outlet 28d of solenoid valve assembly 22, and outlet 210 is fluidly connected to water outlet 19 of nozzle 12. More specifically, inlet portion 218 of pipe 204 receives outlet pipe 28d of solenoid valve assembly 22. A swing clip 71b illustratively secures outlet pipe 28d of solenoid valve assembly 22 to pipe 204 of wireless control module 200. More specifically, a first end 230 of swing clip 71b is pivotally coupled to pin 232 on inlet portion 218 of pipe 204. A second end 234 of swing clip 71b includes an arcuate retainer 236 configured to engage an annular recess 238 on outlet pipe 28d. Outlet portion 220 of pipe 204 is illustratively received within an end of fluid conduit 28e coupled to nozzle 12. O-ring 31 may be positioned between pipe 204 and fluid conduit 28e to provide a fluid seal between them.

[0054] The wireless controller 224 illustratively includes a printed circuit board 240 received within a cavity 222 of the housing 212. The printed circuit board 240 illustratively supports a conventional microprocessor 242. An auxiliary port 244 may also be supported by the printed circuit board 240 and is in electrical communication with the wireless controller 224. The auxiliary port 244 is accessible via an opening 246 in a side wall 248 of the housing 212.

[0055] A wireless communication device (such as wireless transceiver 250) is illustratively supported by a printed circuit board 240 and electrically communicates with a wireless controller 224. Wireless transceiver 250 is configured to wirelessly communicate with a remote device 252 (e.g., directly or indirectly receiving and / or transmitting wireless signals). Such wireless communication can be via known technologies, such as wireless communication in the 2.4 GHz band, including, for example, Wi-Fi, ZigBee, and Bluetooth. Wireless transceiver 250 illustratively includes a wireless radio and an antenna, such as a Wi-Fi module or chip, a ZigBee module, or a Bluetooth module. In one illustrative embodiment, wireless transceiver 250 includes a Wi-Fi chip configured to communicate with a Wi-Fi network 254. As described in detail herein, the wireless communication device illustratively includes transceiver 250 for both receiving and transmitting wireless signals. In other words, transceiver 250 should be understood to include both a receiver and a transmitter. Thus, a receiver can be defined by a transceiver, and more specifically, by transceiver 250 embedded in printed circuit board 240. The use of the term "receiver" is not limited to devices that only receive signals, but may also include devices that also transmit signals (e.g., transceivers).

[0056] Remote device 252 may include a voice recognition and conversion device that wirelessly communicates with transceiver 250. Alternatively, remote device 252 may include a smartphone, tablet, computer, and / or a dedicated remote user interface (i.e., a remote control device). As further described in detail herein, remote device 252 may communicate with wireless control module 200 via the cloud over the Internet. In other illustrative embodiments, remote device 252 may include both a voice recognition and conversion device and at least one of a smartphone, tablet, computer, and / or remote control device.

[0057] Flow sensor 256 is illustratively supported by pipe 204 of body 202 to detect water flow within fluid passage 206 and is in electrical communication with wireless controller 224 and / or valve controller 24. More specifically, flow sensor 256 illustratively includes flow turbine assembly 257, which includes a flow turbine 258 supported by flow turbine holder 260 for rotation. Flow turbine holder 260 may be received within pipe 204 such that water flowing through fluid passage 206 can rotate flow turbine 258. Flow turbine 256 may be a magnetohydrodynamic turbine, which includes a magnet supported by rotor 262 and a sensor or detector 263 supported on printed circuit board 240, the detector 263 being configured to detect rotation of rotor 262. The number of revolutions detected by the sensor is correlated with flow rate and / or flow rate via wireless controller 224 and / or valve controller 24. Valve controller 24 can control electrically operable valve 22 to dispense a predetermined amount of water based on input from flow sensor 256. Additionally, flow sensor 256 can be used to monitor water usage and provide this information to the user. More specifically, water usage information from flow sensor 256 can be provided to controller 224 and transmitted from embedded transceiver 250 to processor 42 to display, for example, information about the water consumption of faucet 10 over time to the user on a display screen (not shown).

[0058] In some illustrative embodiments, temperature sensor 264 may be supported by tube 204 of body 202 to detect the temperature of water flowing through fluid passage 206 and to communicate electrically with wireless controller 224 and / or valve controller 24. Temperature sensor 264 may supplement or replace temperature sensor 54 of valve assembly 20. As further described in detail herein, temperature sensor 54 may be used with wireless controller 224 and / or valve controller 24 to provide temperature indication to a user, provide high-temperature limits, and / or provide heating features.

[0059] The wireless controller 224 illustratively provides means for reading the flow sensor 256, temperature sensor 264, and wireless communication device 250, such as a Wi-Fi chip, ZigBee module, or Bluetooth module for receiving and / or transmitting data. An electronic cable 55 transmits commands (e.g., signals) between the wireless control module 200 and the electronically controlled valve 20 via the valve controller 24. Illustratively, the electronic cable 55 is a serial cable including opposite first end connectors 57a and second end connectors 57b. The first connector 57a is coupled to port 56 of the valve controller 24, while the second connector 57b is coupled to port 244 of the wireless control module 200.

[0060] The modular water circuit design described in detail in this article allows the wireless control module 200 to be inserted between the outlet of the electronic control valve 20 and the water circuit extending through the faucet nozzle 12.

[0061] Illustratively, a serial communication protocol exists between the wireless controller 224 of the wireless control module 200 and the processor 42 of the valve controller 24. The serial communication between the wireless controller 224 and the processor 42 is configured to occur bidirectionally. In addition to transmitting and receiving data signals, an interrupt signal can be used to indicate to the receiver that data transmission is about to begin. The interrupt signal allows both the wireless control module 200 and the processor 42 of the valve controller 24 to enter a low-power sleep mode until one wakes up or activates the other using an interrupt signal. This scheme or protocol allows the two devices 200, 42 to operate continuously for extended periods on battery power, as they are not always fully powered while waiting for or searching for data. The serial protocol used to transmit data can be uniquely defined and is register-based. For example, to set the water state, an auxiliary device or smart nozzle can write the value '1' to register 0x02 to open (e.g., activate) valve 22. As another example, an auxiliary device 30 can request the current water temperature by requesting the value currently stored in register 0x05 in the valve controller 24. Illustratively, all serial message packets use a start byte, a stop byte, a message length byte, and a two-byte cyclic redundancy check (CRC) to ensure data integrity.

[0062] Figure 9This is an illustrative diagram of internet communication with the wireless control module 200. More specifically, the voice recognition and conversion device 252 and the wireless control module 200 may be part of a home network 270 that wirelessly communicates with software stored in the internet 272 (e.g., an internet cloud) via a web interface 274. The web interface 274 may have a conventional design, such as a wireless router or hub, for facilitating communication between the internet cloud 272 and the home network 270. A web portal 276 illustratively provides communication between the voice recognition service 278 and the command parsing routine 280 and the Internet of Things (IoT) hub 282. Additionally, a dedicated remote user interface (such as a smartphone or tablet computer 284) may communicate with the web portal 276. In another illustrative embodiment, the smartphone or tablet computer 284 may communicate directly with the wireless control module 200, for example, via a soft AP Wi-Fi configuration.

[0063] Figure 10 This is an illustrative representation of an illustrative Internet protocol used with the wireless control module 200. For example, the speech recognition and conversion device 252a may include, for instance, a voice or virtual assistant such as Alexa, available on devices (e.g., Echo) from Amazon, Seattle, Washington, USA. In this illustrative embodiment, device 252a communicates with the Alexa speech recognition service 278a and the Alexa voice adapter 280a (e.g., the AWS Lambda computing platform). In another illustrative embodiment, the speech recognition and conversion device 252b may include, for instance, a voice or virtual assistant such as Google Assistant, available from Google, Mountain View, California, USA. In this illustrative embodiment, device 252b communicates with the Google speech recognition service 278b and the Google voice adapter 280b (e.g., Google Cloud capabilities).

[0064] Further reference Figure 9 and Figure 10 The setup of the Internet of Things (IoT) hub 282 for communicating with the controller 224 of the wireless control module 200 is illustratively provided using a webpage originating solely from a remote computing device (such as a smartphone or tablet 284). More specifically, communication between the wireless control module 200 and the voice recognition and conversion device 252 is illustratively provided over Wi-Fi network 270 and the Internet 272 using standard Internet protocols. A setup mechanism is provided for connecting the device 200 to the Internet 272 without requiring the user to download a separate application from a dedicated app store (e.g., the Apple App Store or Google Play Store).

[0065] The illustrative steps for setting up a device (e.g., wireless control module 200) are described in detail below. The advantage of this setup system is that the user can set up the device 200 using a web browser on his or her smartphone or tablet computer 284, without having to download a separate "app" for this one-time setup. In addition to the simplified setup of the device 200, future configuration and control of the device 200 can also be performed through a web portal, and furthermore, using the built-in web browser on the user's smartphone or tablet computer 284.

[0066] The illustrative Wi-Fi web setup process includes the following steps:

[0067] 1. Device 200 will host its own web server and software access point (soft AP).

[0068] 2. The user will connect to the soft AP by selecting the open Wi-Fi network on his or her smartphone or tablet 284.

[0069] 3. The user will open his or her web browser and then enter the IP address or URL of the locally hosted webpage.

[0070] 4. On the soft AP webpage, the user will be asked to select his or her home Wi-Fi SSID and enter his or her password.

[0071] 5. At this point, the soft AP will turn off, and the device will attempt to connect to the home Wi-Fi network 270 using the credentials entered by the user. When this happens, the webpage on the user's smartphone or tablet 284 will be delayed for approximately 20 seconds using asynchronous JavaScript (AJAX) (allowing the user's smartphone or tablet 284 to regain a stable internet connection on the Wi-Fi or cellular network) before being redirected to a globally resolvable web portal.

[0072] 6. Once in the public web portal, the user will create an account to link his or her physical device (e.g., Wi-Fi Voice Faucet 10) to his or her account in the cloud.

[0073] 7. Setup complete. Users can now return to the public web portal at any time to change their device settings or remotely control their devices (e.g., electronic faucet 10).

[0074] Figure 11This diagram illustrates the states of illustrative operation of the electronic faucet 10 disclosed herein. Boxes 302, 304, 306, and 308 represent different operating states or modes of the illustrative electronic faucet 10. More specifically, box 302 represents a first operating state or mode in which the manual valve 20 and the electrically operable valve 22 are closed, such that no water flows through the outlet 19 of the nozzle 12. Box 304 represents a second operating state or mode in which the manual valve 20 is closed and the electrically operable valve 22 is open. In the second operating mode, no water flows through the outlet 19 of the nozzle 12. Box 306 represents a third operating state or mode in which both the manual valve 20 and the electrically operable valve 22 are open, such that water flows through the outlet 19 of the nozzle 12. Box 308 represents a fourth operating state or mode in which the manual valve 20 is open and the electrically operable valve 22 is closed. In the fourth operating mode, no water flows through the outlet 19 of the nozzle 12.

[0075] exist Figure 11 In this document, various illustrative commands for controlling the operation of the electrically operable valve 22 are represented by lines associated with various combinations of the numbers 1 to 12. As described in further detail herein, the valve controller 24 can receive commands from various input devices, such as capacitive sensors(26) and / or voice recognition and conversion devices(252). The valve controller 24 can also distinguish between a “tap” and a “grip” on different parts of the electronic faucet 10 based on signals received from the capacitive sensors(26). More specifically, the valve controller 24 can make this distinction based on the amount of time between the positive and negative slopes of the capacitive signal. A longer duration indicates a “grip,” while a shorter duration indicates a “tap.” Illustratively, a grip is a contact or touch lasting at least 300 milliseconds, while a tap is a contact or touch lasting no more than 300 milliseconds. Additional illustrative details regarding distinguishing between touches on nozzle 12 and / or handle 14 to define taps and grips, identifying different touch patterns, and thereby implementing different functions are disclosed in U.S. Patent No. 8,776,817 to Sawaski et al., U.S. Patent No. 8,613,419 to Rodenbeck et al., and U.S. Patent No. 8,561,626 to Sawaski et al., all of which are expressly incorporated herein by reference.

[0076] Further reference Figure 11The state diagram shows that command 1 is no new input. Command 2 is nozzle tap, where the user touches the nozzle 12 of the faucet 10 for a predetermined duration. Command 3 is sleeve tap, where the user touches the sleeve 15 of the faucet 10 for a predetermined duration. Command 4 is nozzle grip, where the user touches the nozzle 12 for a predetermined duration. Command 5 is sleeve grip, where the user touches the sleeve 15 for a predetermined duration. Command 6 is voice open command, where the user gives an audible "open" voice command to the voice recognition and conversion device 252. Command 7 is voice close command, where the user gives an audible "close" voice command to the voice recognition and conversion device 252. Command 8 is voice assign command, where the user gives an audible "assign" voice command to the voice recognition and conversion device 252. Command 9 is voice heat command, where the user gives an audible "heat" voice command to the voice recognition and conversion device 252. Command 10 is a voice-activated water allocation completion command, initiated after the voice allocation command (Command 8). In this command, after the flow sensor 256 detects that a predetermined amount of water has been allocated, the controller 24 moves the electrically operable valve 22 to the closed position. Command 11 is a heating completion command, initiated after the voice-activated heating command (Command 9). In this command, after the temperature sensor 264 detects that the water temperature exceeds a predetermined value, the controller 24 moves the electrically operable valve 22 to the closed position. Command 12 is a timeout command, in which the controller 24 moves the electrically operable valve 22 to the closed position after the electrically operable valve 22 has been open for a predetermined time.

[0077] Further reference Figure 11 The illustrative manual inputs to the handle 14 of the manual valve 20 are indicated by lines associated with the letters A and B. Manual input A is to place the handle 14 of the manual valve 20 in the closed position, so that no water flows through the manual valve 20. Manual input B is to place the handle 14 of the manual valve 20 in the open position, so that water flows through the manual valve 20.

[0078] Commands to control the operation of the electrically operable valve 22 can be initiated through various inputs associated with the electronic faucet 10. Such inputs may include one or more of voice recognition, capacitive sensing, infrared (IR) sensing, proximity sensing, etc. Once a command is issued, the water flow is controlled, illustratively, by using the controller 24 to track elapsed time and read sensors (e.g., flow sensors 52, 256, temperature sensors 54, 264, etc.), to execute the command. For capacitive sensing, the user can perform a series of touches on one part of the electronic faucet 10 (e.g., double-tapping the faucet 12), or a combination of touches on different parts of the electronic faucet 10 (e.g., gripping the nozzle 12 and moving the manual handle 14 to heat, gripping the nozzle 12 and double-tapping the manual handle 14, etc.).

[0079] exist Figure 11 In the operation shown in the state diagram, the electronic faucet 10 can be controlled via commands input from (multiple) capacitive sensors 26 and voice recognition provided to the wireless control module 200. Starting from state 302, commands 2 (nozzle tap), 3 (sleeve tap), 5 (sleeve grip), 6 (voice open), 8 (voice dispense), and 9 (voice heat) will cause the controller 24 to open the electrically operable valve 22 while the manual valve 20 remains closed. Thus, the electronic faucet 10 is in state 304. The electronic faucet 10 remains in state 302 in response to commands 1 (no new input), 4 (nozzle grip), and 7 (voice close).

[0080] The electronic faucet 10 remains in state 304 in response to command 1 (no new input), command 4 (nozzle grip), command 5 (sleeve grip), command 6 (voice open), command 8 (voice assign), and command 9 (voice heat). Command 2 (nozzle tap), command 3 (sleeve tap), command 7 (voice close), command 10 (voice assign), command 11 (voice heat complete), and command 12 (timeout) return the electronic faucet 10 to state 302. From state 302, moving the manual handle 14 to the open position (manual input B) moves the electronic faucet 10 to state 308.

[0081] From state 304, moving the manual handle 14 to the "open" position (manual input B) moves the electronic faucet 10 to state 306. Moving the manual handle 14 back to the "closed" position (manual input A) returns the electronic faucet 10 to state 304. In state 306, commands 2 (nozzle tap), 3 (sleeve tap), 7 (voice off), 10 (voice assign), 11 (voice heating complete), and 12 (timeout) will cause the controller 24 to close the electrically operable valve 22, while the manual valve 20 remains open. Thus, the electronic faucet 10 is in state 308. The electronic faucet 10 remains in state 306 via commands 1 (no new input), 4 (nozzle grip), 5 (sleeve grip), 6 (voice open), 8 (voice assign), and 9 (voice heating). Command 2 (nozzle tap), Command 3 (sleeve tap), Command 5 (sleeve grip), Command 6 (voice open), Command 8 (voice assign), and Command 9 (voice heat) will return the electronic faucet 10 from state 308 to state 306.

[0082] The electronic faucet 10 remains in state 308 via command 1 (no new input), command 4 (nozzle grip), and command 7 (voice off). From state 308, moving the manual handle 14 to the closed position (manual input A) moves the electronic faucet 10 to state 302. In state 302, the electronic faucet 10 returns to state 308 by moving the manual handle 14 back to the "on" position (manual input B).

[0083] It should be understood that various different commands for the operation of controller 24 can be programmed (e.g., stored in memory or a library). For example, in response to a "wash hands" command, controller 24 can (1) open electrically operable valve 22 for a short preset duration to wet the user's hands, (2) close electrically operable valve 22 for a short preset duration to allow the user to apply soap, and (3) open electrically operable valve 22 again to allow the user to rinse their hands. Controller 24 can close valve 22 again after the short preset duration or only after additional command input from the user. In this operation, the dispensed water can be set to a predetermined warm temperature (e.g., as detected by temperature sensor 54).

[0084] In response to a "brush teeth" command, controller 24 may (1) open electrically operable valve 22 for a short preset duration to wet the user's teeth, (2) close electrically operable valve 22 for a short preset duration to allow the user to apply toothpaste to the toothbrush, and (3) open electrically operable valve 22 again to allow the user to rinse their mouth. Controller 24 may close valve 22 again after the short preset duration or only after additional command input from the user. In this operation, the dispensed water may be set to a predetermined cooler temperature (e.g., as detected by temperature sensor 54). Although the brushing mode is similar to the handwashing mode, illustratively, the programmed operating time and water temperature are different.

[0085] In another illustrative example, the "Fill Object" command causes controller 24 to open electrically operable valve 22 for a preset duration, or until a preset volume is reached, as measured by flow sensor 256, to dispense a set amount of water sufficient to fill the container, and then close electrically operable valve 22. Different commands can be used to dispense different set amounts of water to fill different containers. Illustrative commands may include, for example, "Fill Cup," "Fill Pot," "Fill Gallon," etc.

[0086] The “heat” command can cause the controller 24 to open the electrically operable valve 22 until the temperature of the dispensed water (e.g., detected by the temperature sensor 54) reaches or exceeds a predetermined value.

[0087] Various commands can be initiated through different inputs on faucet 10, including, for example, voice input, capacitive sensors, infrared sensors, etc. For capacitive sensor 26, for example, the user can perform a touch sequence (e.g., double tap) or a combination of touches (e.g., gripping nozzle 12 and turning handle 14 to heat, gripping nozzle 12, and double tapping handle 14). Once a command is issued, microprocessor 42 can be used to track elapsed time and read sensors (e.g., flow sensor, temperature sensor, etc.) to control water flow to execute the command.

[0088] If the electronic faucet 10 is controlled by voice recognition, it is advantageous to reduce the background noise supplied to the voice recognition and conversion device 252. Thus, a laminar flow stabilizer can be provided in the flow path between the valve 22 and the outlet of the nozzle 12. In one illustrative embodiment, the laminar flow stabilizer can be an aerator connected to the outlet 19 of the nozzle 12. More specifically, aerated water can be forced through holes or orifices in a dispersion disc and then through at least one screen, which creates laminar aerated water as it exits the aerator. It will be understood that other types of flow stabilizers can be used at various locations in the flow path.

[0089] Data can be transmitted bidirectionally between the wireless control module 200 and the voice recognition and conversion device 252. More specifically, the device 200 and / or the voice recognition and conversion device 252 illustratively include a speaker to convey information to the user via speech. For example, the device 200 and / or the voice recognition and conversion device 252 can provide information about the unit's battery life, water temperature, heating characteristics, flow rate usage, water quality, water pressure, the volume of water dispensed, desired temperature setting, custom object naming for the dispensed volume (e.g., cup, pot, etc.), custom object naming for other functions (temperature, quality, etc.), and set a timer to turn it on / off at a specified time.

[0090] While the above description illustrates valve assemblies and wireless control modules for use with electronic faucets 10 (such as kitchen faucets), it should be understood that they can be used in conjunction with other devices (such as shower valves, bathtub valves, toilets, etc.).
