CROSS-REFERENCE TO RELATED APPLICATIONS

[0001] This application claims the benefit of U.S. Provisional Application No. 63/326,585, filed April 1, 2022, the entire contents of which is incorporated herein by reference.

FIELD

[0002] The present disclosure generally relates to faucet assemblies. More specifically, the present disclosure relates to faucet assemblies comprising easy-to-reach temperature control mechanisms.

BACKGROUND

[0003] Conventional faucets are designed to provide a continuous stream of water at a range of temperatures. Typically, a user of a conventional faucet may choose their desired water temperature using the same control that they use to turn the faucet on. In conventional faucets, this control is often a handle or a knob located near the base of the faucet body. In addition to allowing users to control the water temperature, conventional faucets often allow users to control or adjust water flow properties such as water pressure and spray pattern to a certain extent.

SUMMARY

[0004] As mentioned above, a conventional faucet generally includes one or more controls (often handles or knobs) located near the base of the faucet body which are configured to both initiate the flow of water through the faucet and to control the temperature of the water. While conventional faucets do provide faucet users with some level of control over the water temperature, that control is often imprecise. For example, in many situations, a faucet user may wish to only marginally change the water temperature, but this may not be possible using an inaccurate control like a knob. Furthermore, since conventional faucet controls are generally located near the base of the faucet body, it is often inconvenient to adjust the water temperature while the faucet is on because adjusting the temperature would require the faucet user to reach through or around the stream of water being deposited from the faucet. There exists a need for a faucet assembly which provides a mechanism for faucet users to easily and precisely control water temperature.

[0005] Accordingly, the present disclosure provides a faucet assembly comprising a temperature control positioned near the faucet spray head. This position is easily accessible by faucet users and does not require faucet users to reach through or around a stream of water in order to control the temperature. The temperature control may be configured to receive a desired water temperature from a faucet user and, in turn, to transmit a signal to a mixing valve to control the water temperature. In some embodiments, the temperature control may include one or more indicator lights which are configured to provide the faucet user with a visual indication of a current water temperature or user’s desired water temperature. This visual indication may provide the user with more accurate knowledge of the water temperature.

[0006] In some embodiments, the temperature control may be a linear assembly or a circular assembly of capacitive touch sensors disposed on the faucet body. Users may control the water temperature by swiping and/or pressing one or more of the capacitive touch sensors. The temperature control may control the water temperature based on which capacitive touch sensors receive user input.

[0007] In some embodiments, the temperature control may be an annular control comprising a magnetic temperature adjustment ring which is free to rotate about the faucet body. The annular control may be configured to detect a position of the temperature adjustment ring by measuring magnetic fields emitted by adjustment ring. The annular control may then control the water temperature based on the position of the adjustment ring.

DETAILED DESCRIPTION

[0086] As discussed above, it is generally difficult to precisely control the water temperature of water deposited by a conventional faucet because the temperature controls of conventional faucets typically comprise one or more knobs or handles located near the base of the faucet. In addition, it is often inconvenient to adjust the water temperature while the faucet is on because adjusting the temperature would require the faucet user to reach through or around the stream of water being deposited from the faucet. As such, the present disclosure provides a faucet assembly comprising an easily accessible temperature control positioned near the faucet spray head.

[0087] FIG. 1 A illustrates a faucet assembly with a temperature adjustment mechanism according to some embodiments of the present disclosure. Specifically, FIG. 1 A shows a faucet assembly 100 comprising a faucet body 102, a spray head 104, a temperature adjustment mechanism 106, a faucet handle 108, and a water inlet 110. In some embodiments, faucet assembly 100 may be configured to connect to a fluid source. Faucet body 102 may house a conduit configured to direct the flow of water from water inlet 110 to spray head 104. Spray head 104 may be configured to transmit water into a water receptacle (e.g., a kitchen sink, a bathroom sink, or a bathtub). In some embodiments, faucet assembly 100 may be a pull-out faucet or a pull-down faucet, i.e., spray head 104 may be connected to a hose housed within faucet body 102 and may be configured to be detached and pulled away from faucet body 102 by a faucet user.

[0088] In some embodiments, faucet handle 108 may be associated with a manual valve. Faucet handle 108 may be configured to cause water to flow from the fluid source and into faucet assembly 100 via water inlet 110. In some embodiments, faucet handle 108 may be configured to control a flow rate of water transmitted into the water receptacle. In some embodiments, faucet assembly 100 may comprise one or more controls in spray head 104 configured to control the water flow. In some embodiments, spray head 104 may comprise one or more controls configured to turn the faucet on/off, control the flow rate of water transmitted into the water receptacle, or to control a spray mode of water transmitted into the water receptacle. [0089] Temperature adjustment mechanism 106 may be configured to receive a user input providing a desired water temperature. After receiving the user input providing the desired water temperature, temperature adjustment mechanism 106 may be configured to increase or decrease the temperature of water flowing through faucet body 102 and spray head 104. In some embodiments, temperature adjustment mechanism 106 may be configured to control the temperature of water flowing through faucet body 102 and spray head 104 by controlling a mixing valve. Temperature adjustment mechanism 106 may be configured to adjust the water temperature in real time as user inputs providing desired water temperatures are received.

[0090] In some embodiments, the mixing valve controlled by temperature adjustment mechanism 106 may be an electromechanical valve (e.g., a solenoid valve). In some embodiments, temperature adjustment mechanism 106 may be configured to control a first electromechanical valve for hot water and a second electromechanical valve for cold water. The first electromechanical valve and the second electromechanical valve may lead to a mixing chamber. In some embodiments, the mixing valve may be located upstream of a manual valve associated with faucet handle 108. In some embodiments, the mixing valve may be located upstream of a manual valve associated with faucet handle 108 and an electromechanical valve configured to control water flow rate. In some embodiments, the mixing valve may be located upstream of an electromechanical flow control valve.

Alternative valve arrangements (possibly comprising one or more additional valves) may be conceivable.

[0091] In some embodiments, temperature adjustment mechanism 106 may be positioned between faucet body 102 and spray head 104. This may provide a faucet user with easy access to temperature adjustment mechanism 106 while the faucet user is using faucet assembly 100.

[0092] FIG. IB shows a block diagram illustrating exemplary connections between faucet assembly 100, a mixing valve control 112, a mixing valve 114, and a fluid source 116. Fluid source 116 may comprise a hot fluid source and a cold fluid source and may be configured to transmit hot water and cold water to mixing valve 116 via separate water flow paths (e.g., separate pipes). In some embodiments, mixing valve control box 112 and mixing valve 114 may be housed beneath a water receptacle into which faucet assembly 100 is configured to deposit water. [0093] In some embodiments, mixing valve 114 may be an electromechanical (e.g., solenoid) valve.

[0094] In some embodiments, temperature adjustment mechanism 106 may receive a user input from a faucet user. The user input may provide a desired water temperature. After receiving the user input, temperature adjustment mechanism 106 may be configured to transmit an input signal 118 to mixing valve control 112. Input signal 118 may be an electronic signal which may be transmitted wirelessly or via a wired connection between temperature adjustment mechanism 106 and mixing valve control 112.

[0095] After receiving input signal 118 from temperature adjustment mechanism 106, mixing valve control 112 may be configured to transmit a control signal 120 to mixing valve 114. Control signal 120 may comprise instructions configured to cause mixing valve to transmit water within a range of the faucet user’s desired water temperature. In some embodiments, control signal 120 may be an electronic signal which may be transmitted wirelessly or via a wired connection between mixing valve control 112 and mixing valve 114.

[0096] Upon receiving control signal 120, mixing valve 114 may be configured to cause fluid source 116 to transmit water 122 to mixing valve 114. Water 122 may comprise hot water and cold water which may be separately transmitted to mixing valve 114. Mixing valve 114 may house a mixing chamber configured to allow the received hot water and the received cold water to mix. In some embodiments, mixing valve 114 may comprise a temperature sensor configured to track the temperature of water in the mixing chamber. In some embodiments, mixing valve 114 may be configured to adjust the ratio of hot water to cold water received from fluid source 116 in order to create water at the user’s desired temperature.

[0097] After water 122 has been received and mixed within mixing valve 114, mixing valve 114 may be configured to transmit mixed water 124 to water inlet 110 of faucet 100. Water inlet 110 may be configured to transmit water 124 to spray head 104 via a fluid connection (e.g., faucet body 102 shown in FIG. 1 A). At this point, water 124 may be transmitted by spray head 104 into a water receptacle.

[0098] Temperature adjustment mechanism 106 shown in FIGs. 1 A-1B may take many forms. In some embodiments, temperature adjustment mechanism 106 may comprise a vertical control assembly configured to adjust the water temperature as the faucet user swipes a finger up or down a vertical array of sensors. In some embodiments, temperature adjustment mechanism 106 may comprise an annular assembly configured to adjust the water temperature as the faucet user twists an annular device wrapped around faucet body 102. In some embodiments, temperature control mechanism 106 may comprise a circular control assembly configured to adjust the water temperature as the faucet user swipes a finger around an array of sensor arranged in a circle.

[0099] FIG. 2 illustrates a faucet with a temperature control assembly having a vertical configuration according to some embodiments of the present disclosure. Specifically, FIG. 2 illustrates a faucet 200 comprising a faucet body 202, a spray head 204, and a temperature control assembly 206. Faucet 200 may be configured to fluidly connect to a fluid source. In some embodiments, faucet body 202 may house a water conduit or a hose configured to transport water from a fluid source to spray head 204. Spray head 204 may be configured to transmit water into a water receptacle (e.g., a kitchen sink, a bathroom sink, or a bathtub).

[0100] In some embodiments, temperature control assembly 206 may include features of temperature control mechanism 106 as shown in FIGs. 1A-1B. Temperature control mechanism 206 may be configured to communicate with a mixing valve control (e.g., mixing valve control 112 shown in FIG. IB) in order to control a mixing valve (e.g., mixing valve 114 shown in FIG. IB) to cause water at the faucet user’s desired water temperature to be deposited by spray head 204.

[0101] Temperature control assembly 206 may comprise one or more controls that are arranged in a line that follows the path from faucet body 202 to spray head 204 and are configured to receive input from a faucet user. In some embodiments, the one or more controls may be one or more capacitive touch sensors, one or more pressure sensors, one or more push buttons, a sliding switch, or a lever. In some embodiments, the faucet user may indicate a desired water temperature by touching and/or pressing a certain portion of temperature control mechanism 206. For example, temperature control assembly 206 may be configured to cause hot water to be deposited from spray head 204 when the faucet user provides input around a top portion of temperature control assembly 206 (e.g., a portion of temperature control assembly 206 that is farthest from spray head 204) and may be configured to cause cold water to be deposited from spray head 204 when the faucet user provides input around a bottom portion of temperature control assembly 206 (e.g., a portion of temperature control assembly that is closest to spray head 204). In some embodiments, the faucet user may lower or increase a current water temperature by swiping one or more fingers along one or more controls of temperature control assembly 206.

[0102] Temperature control assembly 206 may be configured to visually indicate the temperature of water currently being deposited from spray head 204 and/or to visually indicate a desired water temperature that the user has selected.

[0103] As shown in FIG. 2, temperature control assembly 206 may be positioned on faucet body 202 at a location proximal to spray head 204. This may provide the faucet user with easy access to temperature control assembly 206 while the faucet user is using faucet 200. In some embodiments, temperature control assembly 206 may be positioned on faucet body 202 at a location less than or equal to about 5, about 4, about 3, about 2, about 1, or about 0.5 inches from spray head 204. In some embodiments, temperature control assembly 206 may be positioned on faucet body 202 at a location greater than or equal to about 0.1, about 0.2, about 0.3, about 0.4, about 0.5, about 1, or about 1.5 inches from spray head 204.

For example, faucet 300 may be mounted on a countertop above a kitchen sink. As shown, faucet 300 may comprise a faucet body 302, a spray head 304, and a water inlet 308. Water inlet 308 may be configured to receive water from a fluid source. After receiving water from the fluid source, water inlet 308 may be configured to transmit the water into a flow path housed by faucet body 302. In some embodiments, the flow path may comprise a conduit (e.g., a pipe) and/or a hose. The flow path may be configured to direct the water from faucet body 302 to spray head 304. Spray head 304 may be configured to transmit the water from faucet 300 to a water receptacle. In some embodiments, the flow of water through faucet 300 may be initiated when a faucet user moves one or more handles, knobs, and/or buttons. In some embodiments, faucet 300 may comprise a motion detector or presence sensor configured to detect the presence of the faucet user and, upon detecting said presence, initiate the flow of water through faucet 300.

[0106] FIG. 3B shows a view from above of the point of connection between faucet body 302 and spray head 304. As shown, temperature control assembly 306 may be positioned along faucet body 302 proximal to the point of connection between faucet body 302 and spray head 304. Temperature control assembly 306 may be configured to receive user input from a faucet user. After receiving the user input, temperature control assembly 306 may be configured to control a mixing valve based on information contained in the user input. In some embodiments, the user input may comprise information indicating a desired water temperature. In some embodiments, if faucet 300 is turned off when the faucet user provides the user input to temperature control assembly 306, temperature control assembly 306 may be configured to initiate the flow of water through faucet 300.
