Detailed Description

The invention provides an electronic water pipe device accessory. In an exemplary embodiment, the electronic plumbing fixture fitting is an electronic faucet. However, one of ordinary skill in the art will recognize that the electronic plumbing fitting may be an electronic shower system, an electronic shower head, an electronic hand shower, an electronic body sprayer, an electronic side sprayer, or any other electronic plumbing fitting.

An exemplary embodiment of an electronic plumbing fitting 10, such as an electronic faucet 12, is illustrated in fig. 1 and 2. Fig. 1 mainly shows the fluid components and connections of the electronic plumbing fitting 10, and fig. 2 mainly shows the electrical/electronic components and connections of the electronic plumbing fitting 10. An exemplary embodiment of the electronic faucet 12 is shown in fig. 3. Fig. 3 shows the fluid components and the electrical/electronic components of the electronic faucet 12.

In the illustrated embodiment, as best shown in fig. 3, the faucet 12 includes a hub 14, a spout 16, a wand hose 18, a wand 20, and a handle 22. The upstream end of the hub 14 is connected to a mounting surface M (such as a counter or sink). The upstream end of the nozzle 16 is connected to the downstream end of the hub 14. The nozzle 16 is operable to rotate relative to the hub 14. A wand hose 18 extends through the hub 14 and the nozzle 16 and is operable to move within the hub 14 and the nozzle 16. The upstream end of the wand 20 is mounted in the downstream end of the nozzle 16 and is connected to the downstream end of the wand hose 18. The downstream end of the wand 20 includes a discharge outlet 24 through which water is delivered from the tap 12. The wand 20 is operable to be pulled away from the nozzle 16. A handle 22 is connected to one side of the hub 14 and is operable to move relative to the hub 14. While faucet 12 has been described as having a rotatable spout 16, a pull-out or drop-down wand 20, and a handle 22 mounted on hub 14, those of ordinary skill in the art will recognize that in certain embodiments, spout 16 may be fixed relative to hub 14, faucet 12 may not include wand 20, handle 22 may be mounted elsewhere on faucet 12 or remote from faucet 12, faucet 12 may include more than one handle 22, handle 22 may be any mechanically actuated device or user interface, and/or faucet 12 may not include handle 22.

Further, in the illustrated embodiment, as best shown in fig. 1 and 3, the fitment 10 and tap 12 include a hot water line 26, a cold water line 28, a mixed water line 30, and an electronic valve 32. In the illustrated embodiment, the electronic valve 32 is an electronic mixing valve that includes a hot water electronic valve 32h and a cold water electronic valve 32 c.

The upstream end of hot water line 26 is connected to a hot water supply 34, while the upstream end of cold water line 28 is connected to a cold water supply 36. The downstream end of hot water line 26 is connected to electronic valve 32, and the downstream end of cold water line 28 is connected to electronic valve 32. More specifically, the downstream end of the hot water line 26 is connected to a hot water electronic valve 32h, and the downstream end of the cold water line 28 is connected to a cold water electronic valve 32 c.

The upstream end of the mixed water line 30 is connected to an electronic valve 32. More specifically, the upstream end of the mixed water line 30 is connected to a hot water electronic valve 32h and a cold water electronic valve 32 c. The downstream end of the mixed water line 30 is connected to the discharge port 24. In the illustrated embodiment, at least a portion of the mixed water line 30 is a wand hose 18. As described above, the downstream end of wand hose 18 is connected to the upstream end of wand 20, and the downstream end of wand 20 includes a discharge outlet 24, through which discharge outlet 24 water is delivered from faucet 12.

In the illustrated embodiment, each section of the hot water line 26, the cold water line 28, and the mixed water line 30 is shown as including at least one hose, pipe, or channel. However, one of ordinary skill in the art will recognize that each section of the hot water line 26, the cold water line 28, and the mixed water line 30 may include more than one hose, tube, or passage. Similarly, each portion of hot water line 26, cold water line 28, and mixed water line 30 may include a combination of hose(s), pipe(s), and/or channel(s). In an exemplary embodiment, the hose is a flexible hose. However, one of ordinary skill in the art will recognize that other types of hoses may be used. If a portion of the hot water line 26, the cold water line 28, or the mixed water line 30 includes more than one hose, pipe, and/or channel, the hose(s), pipe(s), and/or channel(s) are connected via a connector. In an exemplary embodiment of the flexible hose, the connector is a push-fit connector. However, one of ordinary skill in the art will recognize that other types of connectors may be used.

When it is mentioned that one component of the fitting 10 or the tap 12 is connected to the other component of the fitting 10 or the tap 12, the connection may be direct or indirect. One of ordinary skill in the art will recognize that additional components may be required if the connection is indirect.

In the illustrated embodiment, the fitment 10 and tap 12 include an electronic valve 32, and more particularly, a hot water electronic valve 32h and a cold water electronic valve 32 c. However, one of ordinary skill in the art will recognize that the fitment 10 and tap 12 may include one or more electronic valves. Further, the fitment 10 and the tap 12 may include one or more mechanical valves in parallel or in series with the electronic valve(s). Additionally, while the fitment 10 and the faucet 12 have been described as including the electronic valve 32 as an electronic mixing valve, one of ordinary skill in the art will recognize that the fitment 10 and the faucet 12 may include only the hot water electronic valve 32h or only the cold water electronic valve 32 c.

In the exemplary embodiment, hot water electronic valve 32h and cold water electronic valve 32c are proportional valves, and more specifically, stepper motor actuated valves. However, those of ordinary skill in the art will recognize that the hot water electronic valve 32h and the cold water electronic valve 32c may be any type of electronic valve, including but not limited to solenoid valves and electronic throttle valves.

In the illustrated embodiment, as best shown in fig. 3, the fitment 10 and faucet 12 include an activation sensor 38, such as a toggle sensor. In the exemplary embodiment, activation sensor 38 is a proximity sensor, in particular an infrared sensor. The activation sensor 38 is also referred to as a latch sensor and a continuous flow sensor. In the illustrated embodiment, the activation sensor 38 is mounted on the apex of the nozzle 16. The activation sensor 38 defines an activation zone. In the exemplary embodiment, activation sensor 38 is operable to activate hot and cold water electronic valves 32h and 32c when an object enters the activation zone and to deactivate hot and cold water electronic valves 32h and 32c when an object leaves and reenters the activation zone. As used herein, an "object" may be any part of the user's body or any object that the user uses to trigger activation of the sensor 38. In the exemplary embodiment, the activation region extends substantially upward from activation sensor 38. Furthermore, in an exemplary embodiment, the activation region has a substantially conical shape.

As mentioned above, the activation sensor 38 is a proximity sensor, in particular an infrared sensor. A proximity sensor is a sensor that detects the presence of an object without any physical contact. However, one of ordinary skill in the art will recognize that the activation sensor 38 may be any type of electronic sensor that may be triggered including, but not limited to, other proximity sensors, touch sensors, and image sensors. Exemplary electronic sensors include, but are not limited to, electromagnetic radiation sensors (such as optical sensors and radar sensors), capacitive sensors, inductive sensors, piezoelectric sensors, and multi-pixel optical sensors (such as camera sensors). As further described above, activation sensor 38 is mounted on the apex of nozzle 16. However, one of ordinary skill in the art will recognize that activation sensor 38 may be mounted anywhere on faucet 12 or remotely from faucet 12.

Similarly, as described above, the activation sensor 38 is a switching sensor. However, one of ordinary skill in the art will recognize that the activation sensor 38 may be any type of sensor that provides information useful for determining whether to activate or deactivate the hot water electronic valve 32h and the cold water electronic valve 32c, including but not limited to flow sensors, pressure sensors, temperature sensors, and position sensors.

In the illustrated embodiment, the handle 22 operates as if a standard faucet were used. In other words, the handle 22 may be moved between various positions to indicate a desired temperature, flow rate, and/or volume of water discharged from the faucet 12.

In the illustrated embodiment, as best shown in FIG. 3, the handle 22 operates as in the case of a standard faucet, although the handle 22 does not control a mechanical valve. In other words, the handle 22 may be moved between various positions to indicate a desired temperature, flow rate, and/or volume of water discharged from the faucet 12.

More specifically, with respect to the temperature of the water, the handle 22 may be rotated about the longitudinal axis of the side opening in the hub 14. At one degree of the range of rotation, the position of the handle 22 indicates full hot water (full hot position). At another degree of the range of rotation, the position of the handle 22 indicates full cold water (full cold position). Between the above degrees of the range of rotation, the position of the handle 22 indicates a mix of hot and cold water (mixed temperature position), which is hotter when positioned near the full hot degree of the range of rotation and colder water when positioned near the full cold degree of the range of rotation.

With respect to the flow rate/volume of water, the handle 22 may be moved toward and away from the side opening in the hub 14. At one degree of range of movement, the position of the handle 22 indicates no flow rate/volume of water (fully off position). At another degree of range of movement, the position of the handle 22 indicates the full flow rate/volume of water (fully open position). Between the above degrees of range of movement, the position of the handle 22 indicates an intermediate flow rate/volume of water (less than the fully open position), with a reduced flow rate/volume of water when the position is near the fully closed degree of range of movement, and an increased flow rate/volume of water when the position is near the fully open degree of range of movement.

In the exemplary embodiment, faucet 12 is operable to detect movement of handle 22 and provide information for setting at least one parameter of water flowing through hot water electronic valve 32h and cold water electronic valve 32c based on the movement of handle 22. Faucet 12 is operable to directly or indirectly detect movement of handle 22. In the exemplary embodiment, faucet 12 provides information for setting the temperature, flow rate, and/or volume of water flowing through hot water electronic valve 32h and cold water electronic valve 32c based on movement of handle 22.

Additionally, in the illustrated embodiment, as best shown in FIG. 3, faucet 12 includes a parameter or position sensor 40. In an exemplary embodiment, the parameter or position sensor 40 is operable to detect a state of the handle 22, such as a position or movement of the handle 22, and provide information for setting at least one parameter of the water flowing through the hot water electronic valve 32h and the cold water electronic valve 32c based on the state of the handle 22 (such as the position or movement of the handle 22). The parameter or position sensor 40 is operable to detect a state of the handle 22 (such as a position or movement of the handle 22) ranging from a fully hot position to a fully cold position and from a fully off position to a fully on position. The parameter or position sensor 40 is operable to directly or indirectly detect a state of the handle 22, such as a position or movement of the handle 22. In an exemplary embodiment, based on the state of the handle 22 (such as the position or movement of the handle 22), the parameter or position sensor 40 provides information for setting the temperature, flow rate, and/or volume of water flowing through the hot water electronic valve 32h and the cold water electronic valve 32 c.

An electronic Plumbing fitting, such as an electronic faucet, including a parameter or position sensor operable to detect movement of the handle and provide information for setting at least one parameter, such as temperature and/or volume, of water flowing through the hot water electronic valve 32h and the cold water electronic valve 32c based on the movement of the handle is disclosed in U.S. patent No.9,212,473, assigned to FB Global Plumbing Group LLC, the entire disclosure of which is incorporated herein by reference.

Additionally, in the illustrated embodiment, as best shown in fig. 2 and 3, the accessory 10 and the faucet 12 include a control module 42, a user input module 44, and a power module 46.

The flow assembly of control module 42 includes a plurality of inlets and outlets and a plurality of flow channels. These inlet/outlet and flow passages enable easy management of flow between the incoming flow (i.e., hot water line 26 and cold water line 28) and the outgoing flow (i.e., mixed water line 30 or wand hose 18).

In the illustrated embodiment, as best shown in FIG. 3, the control module 42 is operable to be mounted below a mounting surface M (such as a counter or sink). In an exemplary embodiment, the control module 42 is operable to be mounted on a mounting stem of the fitting 10 or faucet 12. In the illustrated embodiment, the electronic valve 32 is located within the control module 42. In the illustrated embodiment, the control module 42 includes a top or first side and a bottom or second side. The first side is opposite the second side. In the shown embodiment, the second side comprises openings for the hoses and the flow channels.

In the illustrated embodiment, as best shown in FIG. 2, the control module 42 also includes a plurality of electronic components. These components enable the operation of the fitting 10 or the tap 12. More specifically, these components enable activation, deactivation, and control of the electronic valve 32 via user input. The control module 42 includes the electronic valve 32 and a printed circuit board ("PCB") 48. In the illustrated embodiment, a plurality of electronic components are mounted on the PCB 48, including but not limited to a processor 50, a memory 52, a wireless communication chip 54, and a power port 56. Processor 50 receives signals from and sends signals to components of fitting 10 or faucet 12 to control the operation of fitting 10 or faucet 12. For example, the processor 50 receives signals from sensors (described above and in more detail below) and sends signals to the electronic valve 32 to activate, deactivate, and control the electronic valve 32. The memory 52 may store information received from the accessory 10 or components of the faucet 12. This information may also be stored in a remote memory. Exemplary storage locations for remote storage include user input module 44 (where user input module 44 includes storage such as Apple iPhone and Google Android phones), a centralized server provided by the accessory/faucet manufacturer, and cloud services provided by the accessory/faucet manufacturer or third parties such as Google, HomeKit, and IFTTT. In the illustrated embodiment, the remote storage includes a server 58 and a cloud 60.

In the illustrated embodiment, as best shown in fig. 2 and 3, the user input module 44 provides operating instructions to the accessory 10 or the electronic components of the faucet 12. User input module 44 may be any module that enables user input. User input module 44 includes electronic input device(s) 62 and manual input device(s) 64. Exemplary electronic input devices 62 include activation sensors, mobile devices, voice control devices, touch screen devices, and button devices. In the illustrated embodiment, the user input module 44 includes an activation sensor 38, a mobile device 66, and a voice control device 68. Exemplary manual input devices 64 include a handle and a joystick. In the illustrated embodiment, the user input module 44 includes a handle 22. User input module 44 receives input from a user and sends signals to control module 42 or other electronic components of accessory 10 or faucet 12 to control the operation of the components of accessory 10 or faucet 12. For example, user input module 44 receives input from a user and sends signals to processor 50 to activate, deactivate, and control electronic valve 32.

In the illustrated embodiment, some components of user input module 44 (e.g., mobile device 66 and voice-controlled device 68) are connected to control module 42 via a wireless communication connection 70, such as a Wi-Fi connection, while other components of user input module 44 (e.g., activation sensors 38 and parameter or location sensors 40) are connected to control module 42 via a hardwired connection 72. In the illustrated embodiment, some components of user input module 44 (e.g., mobile device 66 and voice-controlled device 68) send signals to and/or receive signals from processor 50 via a wireless communication connection 70 (such as a Wi-Fi connection), while other components of user input module 44 (e.g., activation sensor 38 and parameter or position sensor 40) send signals to and/or receive signals from processor 50 via a hardwired connection 72. However, those of ordinary skill in the art will recognize that each component of user input module 44 may be connected to control module 42 and send and/or receive signals from processor 50 via any type of connection, including other wireless communication connections, such as bluetooth, cellular, Near Field Communication (NFC), Zigbee, and Z-Wave, or hardwired connections.

In the illustrated embodiment, as best shown in fig. 3, three electronic input devices 62 and one manual input device 64 are shown, namely, the activation sensor 38 on the faucet 12, a mobile device 66 that can be held or moved by a user, a voice controlled device 68 located on the mounting surface M, and the handle 22 connected to the hub 14 of the faucet 12 located on the mounting surface M. However, one of ordinary skill in the art will recognize that user input module 44 may include any number of components. Moreover, each component of user input module 44 may be anywhere that it may send and/or receive signals to/from control module 42 and/or other electronic components (such as processor 50) of accessory 10 or faucet 12, or each component of user input module 44 may be integrally formed with accessory 10 or faucet 12 or physically connected to accessory 10 or faucet 12.

In the illustrated embodiment, as best shown in fig. 2 and 3, the server 58 and cloud 60 are connected to the control module 42 via a wireless communication connection 70 (such as a Wi-Fi connection).

In the illustrated embodiment, as best shown in fig. 2 and 3, the power module 46 provides power to the electrical/electronic components of the fitting 10 or faucet 12. In the illustrated embodiment, the power module 46 is operable to be mounted below the mounting surface M. In the illustrated embodiment, the power module 46 is connected to the control module 42 via a hardwired connection 72. In an example embodiment, power module 46 includes battery power. In an example embodiment, the power module 46 includes AC power.

During operation of the electronic valve 32, a user activates, deactivates, and controls the electronic valve 32 using the user input module 44. When the user appropriately triggers the user input module 44, the electronic valve 32 is activated, deactivated, or otherwise controlled. For example, a user may trigger user input module 44 by triggering activation of sensor 38, pressing an appropriate button on mobile device 66, declaring a particular command to voice control device 68, and/or opening, closing, and/or moving handle 22. For voice control, the electronic valve 32 is activated when the user says "open faucet". Similarly, when the user says "turn off the faucet", the electronic valve 32 is deactivated. In addition, when the user says "raise temperature", "lower temperature", "increase flow", or "decrease flow", the electronic valve 32 is controlled to complete the requested action. These commands may be predetermined. Further, the commands may be customizable. For example, the user may activate the electronic valve 32 by saying "start flow" instead of "open tap". Similarly, the user may deactivate the electronic valve 32 by saying "stop flow" instead of "turn off the faucet".

As used herein, "actuating a valve" refers to moving the valve to an open position or maintaining the valve in an open position regardless of the volume or temperature of the flowing water, and "deactivating a valve" refers to moving the valve to a fully closed position.

When referring to activating or deactivating the electronic valve 32 "when the user appropriately triggers the user input module 44," the electronic valve 32 may be activated or deactivated immediately upon triggering the user input module 44, or the electronic valve 32 may be activated or deactivated after a predetermined period of time after triggering the user input module 44.

In the illustrated embodiment, the fitment 10 and faucet 12 include sensors. In the illustrated embodiment, the sensors include an activation sensor 38, a parameter or position sensor 40, a temperature sensor 74, a flow sensor 76, a pressure sensor 78, and a valve sensor 80. The activation sensor 38 and the parameter or position sensor 40 are described above. The temperature sensor 74 may be operable to detect the temperature of water in the hot water line 26, the cold water line 28, the electronic valve 32, and/or the mixed water line 30 or the wand hose 18. The flow sensor 76 is operable to detect the flow rate of water in the hot water line 26, the cold water line 28, the electronic valve 32, and/or the mixed water line 30 or the wand hose 18. The pressure sensor 78 is operable to detect the pressure of water in the hot water line 26, the cold water line 28, the electronic valve 32, and/or the mixed water line 30 or the wand hose 18. The valve sensor 80 is operable to detect a position of the electronic valve 32 and/or a motor that drives the electronic valve 32. The sensor sends a signal indicative of the detected information to the processor 50.

Information detected by the sensor is used to control the operation of the fitting 10 or faucet 12. Information detected by activation sensor 38 may be used to activate and deactivate accessory 10 or faucet 12. The information detected by the parameter or position sensor 40 may be used to determine the temperature, flow rate and/or volume of water desired by the user. The information detected by the temperature sensor 74 may be used to maintain the temperature of the water being discharged from the fitting 10 or the faucet 12. The information detected by the flow sensor 76 may be used to determine whether there is or maintain the flow rate of water exiting the fitting 10 or faucet 12. The information detected by the pressure sensor 78 may be used to maintain the pressure or determine the volume of water discharged from the fitting 10 or faucet 12. Information detected by the valve sensor 80 may be used to open and close the electronic valve 32.

In the illustrated embodiment, the accessory 10 and the faucet 12 include a clock/timer 82. The clock/timer 82 is operable to provide the date and time of the action or the measurement time interval. For example, the clock/timer 82 may provide the date and time of activation or deactivation of the accessory 10 or faucet 12, or measure the time interval from activation of the accessory 10 or faucet 12 to deactivation of the accessory 10 or faucet 12.

Installation inspection system

In an exemplary embodiment, the fitting 10 or faucet 12 includes an installation inspection system.

In an exemplary embodiment, a user installs the fitting 10 or faucet 12. The installation includes connecting the upstream end of the hot water line 26 to a hot water supply 34 and the upstream end of the cold water line 28 to a cold water supply 36. Further, the installation includes connecting the downstream end of the hot water line 26 to the electronic valve 32 and connecting the downstream end of the cold water line 28 to the electronic valve 32. More specifically, the installation includes connecting the downstream end of the hot water line 26 to the hot water electronic valve 32h, and connecting the downstream end of the cold water line 28 to the cold water electronic valve 32 c.

In an exemplary embodiment, the installation check system includes a mechanism for detecting whether the hot water line 26 is connected to the hot water supply 34 and the cold water line 28 is connected to the cold water supply 36, and a mechanism that corrects the connection of the hot water line 26 to the hot water supply 34 and the connection of the cold water line 28 to the cold water supply 36 if the hot water line 26 is not properly connected to the hot water supply 34 and the cold water line 28 is not properly connected to the cold water supply 36 during installation of the fitting 10 or the faucet 12.

In the exemplary embodiment, processor 50 learns the cold supply temperature by sending a signal to electronic valve 32 to activate and flow cold water. Thus, cold water will be delivered through the fitting 10 or the outlet 24 of the faucet 12. In an exemplary embodiment, all of the cold water will be delivered through the fitting 10 or the drain 24 of the faucet 12. The temperature sensor 74 detects the temperature of the water and sends a signal indicative of the detected temperature to the processor 50. Processor 50 receives signals from temperature sensor 74. The temperature sensor 74 continues to detect the temperature of the water and send a signal indicative of the detected temperature to the processor 50, and the processor 50 continues to receive the signal from the temperature sensor 74 until: (1) the detected temperature has become stable (e.g., has not changed for a period of time sufficient to ensure that the detected temperature is approximately equal to the temperature of the water from the cold water supply, such as thirty seconds), (2) the detected temperature has reached a specified temperature (e.g., below any water temperature that can be reached by the hot water cooling in the hot water line 26), or (3) the water has flowed for a specified period of time (e.g., a period of time required to drain the water located in the cold water line 28). The processor then saves the sensed temperature as the cold supply temperature.

Thus, hot water will be delivered through the fitting 10 or the outlet 24 of the faucet 12. In an exemplary embodiment, all of the hot water will be delivered through the fitting 10 or the discharge outlet 24 of the faucet 12. The temperature sensor 74 detects the temperature of the water and sends a signal indicative of the detected temperature to the processor 50. Processor 50 receives signals from temperature sensor 74. The temperature sensor 74 continues to detect the temperature of the water and send a signal indicative of the detected temperature to the processor 50, and the processor 50 continues to receive the signal from the temperature sensor 74 until: (l) The detected temperature has become stable (e.g., has not changed for a period of time sufficient to ensure that the detected temperature is approximately equal to the temperature of the water from the hot water supply, such as thirty seconds), (2) the detected temperature has reached a specified temperature (e.g., above any water temperature that may be reached by the cold water warming in the cold water line 28), or (3) the water has flowed for a specified period of time (e.g., a period of time required to drain the water located in the hot water line 26). The processor then saves the sensed temperature as the heat supply temperature.

In the exemplary embodiment, once processor 50 has knowledge of at least one of the cold supply temperature and the hot supply temperature, processor 50 determines whether hot water line 26 is connected to hot water supply 34 and cold water line 28 is connected to cold water supply 36 (i.e., whether hot water line 26 and cold water line 28 are reversed).

In the exemplary embodiment, processor 50 initially determines whether hot water line 26 and cold water line 28 are reversed by comparing the cold supply temperature to a cold supply temperature threshold (i.e., cold water supply 36 cannot achieve a temperature above that temperature, such as 100 ° f). If the cold supply temperature is above the cold supply temperature threshold, the hot water line 26 and the cold water line 28 are reversed. In this case (i.e. the pipeline is reversed) further action needs to be taken (as described below). If the cold supply temperature is not above or below the cold supply temperature threshold, the hot and cold water lines 26, 28 may still be reversed (e.g., if the hot water supply 34 has been depleted). In this case, the processor 50 then determines whether the hot water line 26 and the cold water line 28 are reversed by comparing the cold supply temperature with the hot supply temperature. In the exemplary embodiment, hot water line 26 and cold water line 28 are reversed if the cold supply temperature is greater than the hot supply temperature. In the exemplary embodiment, hot water line 26 and cold water line 28 are reversed if the cold supply temperature is greater than the hot supply temperature by a differential supply temperature threshold (e.g., 15 ° f). The differential supply temperature threshold eliminates the possibility of the cold supply temperature being higher than the hot supply temperature due to reasons other than the hot and cold water lines 26, 28 being reversed. In these cases (i.e., the pipeline is reversed), further action (as described below) needs to be taken. In the exemplary embodiment, hot water line 26 and cold water line 28 are not reversed if the cold supply temperature is not higher or lower than the hot supply temperature. In the exemplary embodiment, hot water line 26 and cold water line 28 are not reversed if the cold supply temperature is not above or below the hot supply temperature differential supply temperature threshold. In these cases (i.e., the pipelines are not connected in reverse), no further action is required.

In the exemplary embodiment, processor 50 learns the cold water temperature by sending a signal to electronic valve 32 to activate and cause water to flow primarily out of cold water line 28. Thus, primarily cold water will be delivered through the fitting 10 or the outlet 24 of the faucet 12. As used herein, "flowing water primarily out of the cold water line" and "primarily cold water" refer to flowing more water comprising cold water than hot water, and more water comprising cold water than hot water. The temperature sensor 74 detects the temperature of the water and sends a signal indicative of the detected temperature to the processor 50. Processor 50 receives signals from temperature sensor 74. The temperature sensor 74 continues to detect the temperature of the water and send a signal indicative of the detected temperature to the processor 50, and the processor 50 continues to receive the signal from the temperature sensor 74 until: (1) the detected temperature becomes stable (e.g., does not change for a period of time sufficient to ensure that the detected temperature is approximately equal to the temperature of the flowing water, such as thirty seconds), (2) the detected temperature has reached a specified temperature (e.g., below any water temperature that may be reached by the cooling of the hot water in the hot water line 26), or (3) the water has flowed for a specified period of time (e.g., a period of time required to drain the water located in the cold water line 28).

The processor then saves the sensed temperature as the hot water temperature.

In the exemplary embodiment, once processor 50 has knowledge of at least one of the cold water temperature and the hot water temperature, processor 50 determines whether hot water line 26 is connected to hot water supply 34 and cold water line 28 is connected to cold water supply 36 (i.e., whether hot water line 26 and cold water line 28 are reversed).

In the exemplary embodiment, processor 50 initially determines whether hot water line 26 and cold water line 28 are reversed by comparing the cold water temperature to the hot water temperature. In the exemplary embodiment, hot water line 26 and cold water line 28 are reversed if the cold water temperature is greater than the hot water temperature. In the exemplary embodiment, hot water line 26 and cold water line 28 are reversed if the cold water temperature is greater than the hot water temperature by a differential water temperature threshold (e.g., 1 ° F). The differential water temperature threshold eliminates the possibility that the cold water temperature is higher than the hot water temperature due to reasons other than the hot water line 26 and the cold water line 28 being connected in reverse. In these cases (i.e., the pipeline is reversed), further action (as described below) needs to be taken. In the exemplary embodiment, hot water line 26 and cold water line 28 are not reversed if the cold water temperature is not higher or lower than the hot water temperature.

In these cases (i.e., the pipelines are not connected in reverse), no further action is required.

In an exemplary embodiment, the cold supply temperature threshold, the hot supply temperature threshold, the differential supply temperature threshold, the cold water temperature threshold, the hot water temperature threshold, and the differential water temperature threshold may vary depending on the geographic region in which the fitting 10 or the faucet 12 is installed and operated, as the geographic region may affect the temperature of the water in the hot water line 26, the hot water supply 34, the cold water line 28, and the cold water supply 36 (e.g., the groundwater in the south region may be warmer than in the north region, and the rates at which the water in the hot supply line and the water in the cold supply line may warm up may be different in the south and north regions). The cold supply temperature threshold, hot supply temperature threshold, differential supply temperature threshold, cold water temperature threshold, hot water temperature threshold, and differential water temperature threshold may also vary depending on the time of year that the fitting 10 or faucet 12 is installed and operated, as the time of year may affect the temperature of the water in the hot water line 26, hot water supply 34, cold water line 28, and cold water supply 36 (e.g., groundwater may be warmer in summer than winter, and the rate at which water in the hot and cold supply lines heats up may be different in summer and winter).

In an exemplary embodiment, if the installation check system determines during installation that the hot water line 26 is not properly connected to the hot water supply 34 and the cold water line 28 is not properly connected to the cold water supply 36 (i.e., the hot water line 26 and the cold water line 28 are reversed), the installation check system notifies the user that the installation is incorrect and requests instructions from the user regarding correcting the connection of the hot water line 26 to the hot water supply 34 and the connection of the cold water line 28 to the cold water supply 36.

In an exemplary embodiment, if the installation check system detects during installation that the hot water line 26 is not properly connected to the hot water supply 34 and the cold water line 28 is not properly connected to the cold water supply 36 (i.e., the hot water line 26 and the cold water line 28 are reversed), the installation check system automatically corrects for the connection of the hot water line 26 to the hot water supply 34 and the connection of the cold water line 28 to the cold water supply 36.

In an exemplary embodiment, to calibrate (either on command by the user or automatically) the connection of the hot water line 26 to the hot water supply 34 and the connection of the cold water line 28 to the cold water supply 36, the processor 50 designates the initial hot water electronic valve 32h as the new cold water electronic valve 32c and designates the initial cold water electronic valve 32c as the new hot water electronic valve 32 h.

In an exemplary embodiment, shortly after installation of the fitting 10 or faucet 12, the installation check system detects whether the hot water line 26 is properly connected to the hot water supply 34 and the cold water line 28 is properly connected to the cold water supply 36. In an exemplary embodiment, the installation check system periodically detects whether the hot water line 26 is properly connected to the hot water supply 34 and the cold water line 28 is properly connected to the cold water supply 36 throughout the life of the fitting 10 or faucet 12.

In an exemplary embodiment, the fitment 10 or faucet 12 includes a hot water or child resistant mode. The hot water or child resistant mode enables the user to set a maximum temperature suitable for the house or other structure in which the fitment 10 or faucet 12 is installed. The hot water or child-resistant mode may be enabled and disabled by the user. When the hot water or safety mode is enabled, the fitting 10 or faucet 12 can only dispense water at or below a set maximum temperature. When the hot water or child resistant mode is disabled, the fitment 10 or tap 12 is able to dispense water above a set maximum temperature. In an exemplary embodiment, the installation check system disables the hot water or child-resistant mode prior to detecting whether the hot water line 26 is properly connected to the hot water supply 34 and the cold water line 28 is properly connected to the cold water supply 36 during installation of the fitting 10 or faucet 12.
