Patent Description:
Dispensers for liquids or ice are typically provided in refrigeration appliances, such as refrigerators, freezers, and vending machines. In certain of such appliances, both hot and cold water may be provided. Moreover, in some appliances, coffee or other beverages may be dispensed as well. Often, these dispensers include some sort of recess or compartment into which a container or vessel, such as a cup, is placed to receive the dispensed substance.

In many instances, a conduit for dispensing liquids extends downward into a dispenser recess. As an example, a liquid conduit may extend in front of or behind an ice nozzle. Such configurations may be unsightly and aesthetically unappealing to users. Moreover, they may complicate assembly and, in some conditions, interfere with the movement of ice through the ice nozzle (e.g., by blocking a portion of the passage of the ice nozzle or restricting movement of the ice nozzle). It may be desirable to selectively change or vary the characteristics of the liquids dispensed through the conduit. For example, containers of different sizes may be easier to fill if the spray angle or flow rate from conduit is varied. However, incorporating additional liquid conduits may exasperate the above-described issues.

In additional or alternative instances, lighting may be provided for the dispenser compartment to assist the user in placing the container so as to receive the dispensed substance. Typically, such lighting is an incandescent bulb placed in a top portion of the compartment. While such a bulb will generally illuminate the compartment sufficiently, the bulb does not provide much information to a user. <CIT> discloses an apparatus, system, and method of illumination relative to an appliance. A programmable controller activates one ore more light sources automatically based on a trigger or sensed condition. The controller dynamically adjusts the one or more light sources in a closed loop fashion. <CIT> describes a dispensing unit which is operatively associated with a refrigeration appliance for selectively dispensing water and ice at a dispensing station. The dispensing unit includes an actuator that is movable to selected positions in order to support the dispensing of the water and ice. <CIT> discloses a refrigerator comprising a refrigerator compartment and a freezer compartment; a pair of refrigerator compartment doors to open and close the refrigerator compartment, and having an ice maker and a dispenser; a main water tank at the refrigerator compartment to cool supplied water; a water purifying device to purify the supplied water; a sub-water tank at the refrigerator compartment door to cool the supplied water; a water supply path through which the water purifying device, the main water tank, the sub-water tank, the dispenser and the ice maker are in connection with each other; a first branch valve at the water supply path and connected with outlet ports of the water purifying device. <CIT> discloses a refrigerator with a distributor capable of outputting cold and warm water consisting of a box with a cold storage chamber and a freezing chamber and doors to the storing space. <CIT> provides a water dispenser as part of a refrigerator, wherein the water dispenser includes a main part that is provided with a water intaking space of injecting by the profile wall in the main part, wherein the water dispenser further includes a flexible line way on the profile wall and lamps on the board of the flexible line way. <CIT> describes a cooling device comprising a body, wherein foods and beverages to be cooled are placed, at least one door which provides access to the body inner volume when opened, a water receptacle which is dispose preferably to the door or body surface facing the inner volume or which is connected directly to the mains, and a water dispenser which provides the water in the water receptacle to be transmitted outside when desired and which is illuminated. <CIT> is related to a refrigerator which removes foreign material from water which is discharged to a dispenser unit by detachably attaching a filter unit at an outlet unit, thereby providing clean water to a user. <CIT> describes a refrigerator and a distribution system for the same. The distribution system comprises an ice conveying path with a first end part and a fluid conveying path with a second end part, wherein the first end part is limited by an anti-splashing part with an oblique wall.

Accordingly, a refrigerator having a dispenser assembly incorporating features addressing one or more of the above-described issues would be useful. In particular, it would be advantageous for a dispenser assembly to include features for improving liquid dispensing or lighting at an ice dispenser.

However, the claimed subject matter is defined by independent claim <NUM>. The dependent claims <NUM> to <NUM> cover preferred aspects of the present invention.

In other exemplary aspects of the present disclosure, a refrigerator appliance is provided. The refrigerator appliance includes a cabinet, an ice maker attached to the cabinet, a dispenser recess defined on the refrigerator appliance in selective communication with the ice maker, a dispenser conduit disposed within the dispenser recess, and a light source. The dispenser conduit includes a chute wall. The chute wall defines an ice passage permitting ice therethrough, a fluid inlet, and a fluid outlet. The fluid inlet is positioned radially outward from the ice passage in fluid communication with a fluid source selectively supplying a fluid flow thereto. The fluid outlet is defined through the chute wall in downstream fluid communication with the fluid inlet. The light source is mounted within the chute wall and directed toward the dispenser recess.

As used herein, the terms "first," "second," and "third" may be used interchangeably to distinguish one component from another and are not intended to signify location or importance of the individual components. The terms "upstream" and "downstream" refer to the relative flow direction with respect to fluid flow in a fluid pathway. For example, "upstream" refers to the flow direction from which the fluid flows, and "downstream" refers to the flow direction to which the fluid flows. The terms "includes" and "including" are intended to be inclusive in a manner similar to the term "comprising. " Similarly, the term "or" is generally intended to be inclusive (i.e., "A or B" is intended to mean "A or B or both," except as otherwise indicated).

<FIG> provides a perspective view of a refrigerator appliance <NUM> according to an exemplary embodiment of the present disclosure. Refrigerator appliance <NUM> includes a cabinet or housing <NUM> that defines a vertical direction V, a lateral direction L, and a transverse direction T. The vertical direction V, lateral direction L, and transverse direction are all mutually perpendicular and form an orthogonal direction system. Housing <NUM> extends between a top <NUM> and a bottom <NUM> along a vertical direction V. Housing <NUM> defines chilled chambers for receipt of food items for storage. In particular, housing <NUM> defines a fresh food chamber <NUM> positioned at or adjacent top <NUM> of housing <NUM> and a freezer chamber <NUM> arranged at or adjacent bottom <NUM> of housing <NUM>. As such, refrigerator appliance <NUM> is generally referred to as a bottom mount refrigerator. It is recognized, however, that the benefits of the present disclosure apply to other types and styles of refrigerator appliances such as, for example, a top mount refrigerator appliance or a side-by-side style refrigerator appliance. Consequently, the description set forth herein is for illustrative purposes only and is not intended to be limiting in any aspect to any particular refrigerator chamber configuration.

Refrigerator doors <NUM> are rotatably hinged to an edge of housing <NUM> for selectively accessing fresh food chamber <NUM>. In addition, a freezer door <NUM> is arranged below refrigerator doors <NUM> for selectively accessing freezer chamber <NUM>. Freezer door <NUM> may be coupled to a freezer drawer (not shown) slidably mounted within freezer chamber <NUM>. Refrigerator doors <NUM> and freezer door <NUM> are shown in the closed configuration in <FIG>.

Refrigerator appliance <NUM> also includes a dispensing assembly <NUM> for dispensing liquid water or ice. Dispensing assembly <NUM> includes a dispenser <NUM> positioned on or mounted to an exterior portion of refrigerator appliance <NUM> (e.g., on one of doors <NUM>). Dispenser <NUM> includes a discharging outlet <NUM> for accessing ice and liquid water. An actuating mechanism <NUM>, shown as a paddle, is mounted below discharging outlet <NUM> for operating dispenser <NUM>. In alternative exemplary embodiments, any suitable actuating mechanism may be used to operate dispenser <NUM>. For example, dispenser <NUM> can include a sensor (such as an ultrasonic sensor) or a button rather than the paddle. A user interface panel <NUM> is provided for controlling the mode of operation. For example, user interface panel <NUM> includes a plurality of user inputs, such as a water dispensing button and an ice-dispensing button, for selecting a desired mode of operation such as crushed or non-crushed ice.

Discharging outlet <NUM> and actuating mechanism <NUM> are an external part of dispenser <NUM> and are mounted in a dispenser recess <NUM>, defined at least partially by a dispenser back wall <NUM>. Dispenser recess <NUM> is defined at a predetermined elevation convenient for a user to access ice or water and enabling the user to access ice without the need to bend-over and without the need to open doors <NUM>. In the exemplary embodiment, dispenser recess <NUM> is positioned at a level that approximates the chest level of a user.

In exemplary embodiments may include a processing device or controller <NUM> operably coupled to (e.g., in wireless or electrical communication with) one or more portions of ice making assembly <NUM> or dispensing assembly <NUM>. In some such embodiments, operation of ice making assembly <NUM> or dispensing assembly <NUM> is controlled by controller <NUM>, as will be described below. For example, controller <NUM> may be operably coupled to control panel <NUM> for user or automatic selection of certain features and operations of ice making assembly <NUM> or dispensing assembly <NUM>.

Controller <NUM> includes memory (e.g., non-transitive memory) and one or more processing devices such as microprocessors, CPUs or the like, such as general or special purpose microprocessors operable to execute programming instructions or micro-control code associated with operation of refrigerator appliance <NUM>. The memory can represent random access memory such as DRAM, or read only memory such as ROM or FLASH. The processor executes programming instructions stored in the memory. For certain embodiments, the instructions include a software package configured to operate appliance <NUM>. The memory can be a separate component from the processor or can be included onboard within the processor. Alternatively, controller <NUM> may be constructed without using a microprocessor, for example, using a combination of discrete analog or digital logic circuitry (such as switches, amplifiers, integrators, comparators, flip-flops, AND gates, and the like) to perform control functionality instead of relying upon software.

<FIG> provides a perspective view of a door of refrigerator doors <NUM>. Refrigerator appliance <NUM> includes a sub-compartment <NUM> defined on refrigerator door <NUM>. Sub-compartment <NUM> is often referred to as an "icebox. " Sub-compartment <NUM> extends into fresh food chamber <NUM> when refrigerator door <NUM> is in the closed position. Additionally or alternatively, icebox compartment <NUM> may be defined within door <NUM> and extend into freezer chamber <NUM>.

In certain embodiments, an ice maker or ice making assembly <NUM> and an ice storage bin <NUM> (<FIG>) are positioned or disposed within sub-compartment <NUM>. Thus, ice is supplied to dispenser recess <NUM> (<FIG>) from the ice making assembly <NUM> or ice storage bin <NUM> in sub-compartment <NUM> on a back side of refrigerator door <NUM>. Chilled air from a sealed system (not shown) of refrigerator appliance <NUM> may be directed into sub-compartment <NUM> in order to cool ice making assembly <NUM> or ice storage bin <NUM>. In alternative exemplary embodiments, a temperature of air within sub-compartment <NUM> may correspond to a temperature of air within fresh food chamber <NUM>, such that ice within ice storage bin <NUM> melts over time.

An access door <NUM> may be hinged to refrigerator door <NUM>. Access door <NUM> permits selective access to freezer sub-compartment <NUM>. Any manner of suitable latch <NUM> is included with freezer sub-compartment <NUM> to maintain access door <NUM> in a closed position. As an example, latch <NUM> may be actuated by a consumer in order to open access door <NUM> for providing access into freezer sub-compartment <NUM>. Access door <NUM> can also assist with insulating freezer sub-compartment <NUM>, e.g., by thermally isolating or insulating freezer sub-compartment <NUM> from fresh food chamber <NUM>.

<FIG> provides a perspective view of refrigerator door <NUM> with access door <NUM> shown in an open position. As may be seen in <FIG>, ice making assembly <NUM> is positioned or disposed within freezer sub-compartment <NUM>. In some embodiments, ice making assembly <NUM> includes a mold body or casing <NUM> for the receipt of water for freezing. In particular, mold body <NUM> may receive liquid water and such liquid can freeze therein and form ice cubes. Optionally, an ice ejector <NUM> may be provided to direct ice cubes to dispensing assembly <NUM>. As shown, ejector <NUM> includes an ejector motor <NUM> operably attached to one or more ejector arms <NUM>. When activated, ejector motor <NUM> motivates (e.g., rotates) ejector arm <NUM> within ice making assembly <NUM> to remove ice cubes once formed within mold body <NUM>. Ice bucket or ice storage bin <NUM> is positioned below ejector <NUM> and receives the ice from ice mold <NUM>. In certain embodiments, controller <NUM> (<FIG>) operates various components of ice making assembly <NUM> to execute selected system cycles and features. For example, controller <NUM> is operably coupled to motor <NUM>. Under certain conditions, controller <NUM> can selectively activate and operate the motor <NUM>.

From ice storage bin <NUM>, the ice can enter dispensing assembly <NUM> and be accessed by a user, as discussed above. In such a manner, ice making assembly <NUM> can produce or generate ice. It is understood that additional or alternative embodiments may include other features for generating certain types of ice, such as soft or nugget ice.

<FIG> provides a cross-sectional side view of dispensing assembly <NUM> of refrigerator appliance <NUM>. <FIG> provides a lower perspective view of dispensing assembly <NUM>. As shown, dispensing assembly <NUM> includes a dispenser conduit <NUM> positioned at least partially within one of refrigerator doors <NUM>. For instance, dispenser conduit <NUM> may generally correspond to discharging outlet <NUM> (<FIG>), and may serve to guide ice into dispenser recess <NUM>. In some embodiments, dispenser conduit <NUM> includes a top piece or portion <NUM> and a bottom piece or portion <NUM> that are connected or joined together at joint <NUM>. It should be understood that dispenser conduit <NUM> shown in <FIG> is provided by way of example only and that, in alternative exemplary embodiments, dispenser conduit <NUM> may be formed as a single piece or as more than two pieces (e.g., three, four, or more pieces).

Dispenser conduit <NUM> defines an ice passage <NUM>. Ice passage <NUM> of dispenser conduit <NUM> is configured for directing ice from ice making assembly <NUM> to dispenser recess <NUM>. In particular, ice passage <NUM> of dispenser conduit <NUM> (e.g., defined by an inner surface <NUM> of one or more chute walls <NUM>) extends between an inlet <NUM> and an outlet <NUM>. Inlet <NUM> of ice passage <NUM> is positioned at or adjacent ice making assembly <NUM> (<FIG>) (e.g., below ice storage bin <NUM>), and outlet <NUM> of ice passage <NUM> is positioned at or adjacent a top portion of dispenser recess <NUM>, e.g., and forms or corresponds to discharging outlet <NUM>. An axial direction A may be defined by a portion of dispenser conduit <NUM> (e.g., bottom portion <NUM>). Optionally, axial direction A may be defined parallel to vertical direction V.

As shown, inlet <NUM> of ice passage <NUM> may be positioned above outlet <NUM> of ice passage <NUM> along the vertical direction V. In some such embodiments, gravity urges ice (e.g., ice cubes or nuggets) from ice storage bin <NUM> into and through ice passage <NUM> of dispenser conduit <NUM> to outlet <NUM> of ice passage <NUM>. Inlet <NUM> of ice passage <NUM> may also be offset from outlet <NUM> of ice passage <NUM> along one or more directions that are perpendicular to the vertical direction V (e.g., the transverse direction T or lateral direction L). In some such embodiments, inlet <NUM> of ice passage <NUM> is unaligned with outlet <NUM> of ice passage <NUM> along the vertical direction V, as shown in <FIG>. Inlet <NUM> of ice passage <NUM> may also have a larger cross-sectional area (e.g., in a plane that is perpendicular to the vertical direction V) than outlet <NUM> of ice passage <NUM>. Thus, dispenser conduit <NUM> may funnel ice through ice passage <NUM> of dispenser conduit <NUM> from inlet <NUM> of ice passage <NUM> to outlet <NUM> of ice passage <NUM>.

In some embodiments, a duct door <NUM> is positioned within dispenser conduit <NUM>. For instance, duct door <NUM> may be at or adjacent the joint <NUM> between top portion <NUM> and bottom portion <NUM> of dispenser conduit <NUM>. Duct door <NUM> is selectively adjustable (e.g., rotatable) between an open position (shown in <FIG>) and a closed position. In the closed position, duct door <NUM> is positioned between dispenser recess <NUM> and freezer sub-compartment <NUM>. Thus, duct door <NUM> may block or hinder air flow between dispenser recess <NUM> and freezer sub-compartment <NUM> and reduce heat transfer between dispenser recess <NUM> and freezer sub-compartment <NUM>. Conversely, in the open position, duct door <NUM> is not positioned between dispenser recess <NUM> and freezer sub-compartment <NUM>. Thus, nugget ice from ice making assembly <NUM> may flow through ice passage <NUM> to outlet <NUM> of ice passage <NUM> without impacting duct door <NUM>. Duct door <NUM> may normally be in the closed position and may shift to the open position when a user operates actuating mechanism <NUM> (<FIG>). Dispenser conduit <NUM> may be sized and shaped, e.g., with a recess <NUM>, for permitting movement or rotation of duct door <NUM> between the open and closed positions within dispenser conduit <NUM>.

Along with ice passage <NUM>, one or more fluid inlets and corresponding fluid outlets are defined through a portion of dispenser conduit <NUM>, as will be described in detail below.

Turning now to <FIG> and <FIG>, multiple schematic views are provided illustrating various elements of exemplary embodiments of dispensing assembly <NUM>. In some embodiments, a discrete first fluid path <NUM> and second flow path <NUM> may be defined in fluid parallel relative to each other.

As illustrated, dispensing fluid (e.g., water) may be selectively or alternately directed from dispenser conduit <NUM> through first fluid path <NUM> or second flow path <NUM> from one or more fluid sources (e.g., a hot water source <NUM> and a cold water source <NUM>). Thus, characteristics of the fluid flow to a container <NUM> (e.g., cup, bottle, etc.) within dispenser recess <NUM> may be varied based on one or more conditions. In some such embodiments, the flow rate of fluid dispensed from first fluid path <NUM> (e.g., volumetric flow rate of water exiting dispenser conduit <NUM> from first fluid path <NUM> through one or more first fluid outlets <NUM>) may be greater than the flow rate of fluid dispensed from second flow path <NUM> (e.g., volumetric flow rate of water exiting dispenser conduit <NUM> from second flow path <NUM> through one or more second fluid outlets <NUM>). In other words, first fluid path <NUM> may dispense fluid at a first rate while second flow path <NUM> dispenses fluid at a second flow rate that is less than the first flow rate. Advantageously, dispensing assembly <NUM> may thus selectively change the flow rate of fluid dispensed therefrom.

In some embodiments, a multi-path valve <NUM> is provided downstream from the fluid source(s) (e.g., hot water source <NUM> and cold water source <NUM>) and upstream from the fluid outlets <NUM>, <NUM> (e.g., <FIG>) of dispenser conduit <NUM>. As shown in the exemplary embodiments of <FIG>, multi-path valve <NUM> is mounted within a refrigerator door <NUM> (e.g., <FIG>) and upstream from the first and second fluid inlets <NUM>, <NUM> (e.g., <FIG>). Optionally, multi-path valve <NUM> may be provided as an electronic valve (e.g., having an electrically-controlled solenoid) to change or alternate the position (e.g., flow path) within multi-path valve <NUM>.

During use, multi-path valve <NUM> may be moved or operated (e.g., manually or as directed by controller <NUM>) to selectively or alternately direct the fluid flow through the first and second fluid paths <NUM>, <NUM>. In other words, multi-path valve <NUM> is positioned in upstream fluid communication with first fluid outlet(s) <NUM> and second fluid outlet(s) <NUM>(e.g., <FIG>) to control which outlet(s) fluid (e.g., water) flows from. Multi-path valve <NUM> may be moved between a first position and a second position. In the first position, water is directed from water source(s) <NUM>, <NUM> to the first fluid path <NUM>, while restricting water flow to the second fluid path <NUM>. In the second position, water is directed from water source(s) <NUM>, <NUM> to the second fluid path <NUM>, while restricting water flow to the first fluid path <NUM>.

In optional embodiments, a pressure-regulating valve <NUM> is provided upstream from dispenser conduit <NUM> or multi-path valve <NUM> to selectively control or direct the pressure of fluid to the fluid paths <NUM>, <NUM>. For instance, pressure- regulating valve <NUM> may be operably coupled to controller <NUM>, which is configured to selectively limit fluid flow from pressure-regulating valve <NUM> according to one or more predetermined pressure values. Additionally or alternatively, controller <NUM> may be configured to provide a constant predetermined pressure for fluid flow from pressure-regulating valve <NUM>.

In certain embodiments, controller <NUM> is configured to control or direct movement of multi-path valve <NUM> between a first and second position according a user input (e.g., received at user interface <NUM>) corresponding to a desired fluid paths <NUM>, <NUM> or container size (e.g., according to a user input or an automatic determination of an appropriate fluid flow path based on the size of a container <NUM> within dispenser recess <NUM>).

In additional or alternative embodiments, controller <NUM> is configured to control or direct movement of multi-path valve <NUM> between a first and second position automatically (e.g., without direct input or signals indicative of a desired flow path from a user). As illustrated in <FIG>, a proximity sensor <NUM> may be operably coupled to controller <NUM> and directed toward dispenser recess <NUM>. For instance, proximity sensor <NUM> may be mounted on dispenser conduit <NUM> such that a container <NUM> within recess <NUM> is positioned below proximity sensor <NUM>. However, it is understood that any other suitable location for proximity sensor <NUM> (e.g., outside or spaced apart from dispenser conduit <NUM>) to detect a container <NUM> below conduit <NUM> may further be provided.

Generally, proximity sensor <NUM> may be operable to detect the presence of a presented object (e.g., container <NUM>). Optionally, proximity sensor <NUM> may be operable to measure the height of the presented container <NUM> (e.g., the distance between proximity sensor <NUM> and presented container <NUM>). In exemplary embodiments, proximity sensor <NUM> can be any suitable device for detecting or measuring distance to an object. For example, proximity sensor <NUM> may be an ultrasonic sensor, an infrared sensor, or a laser range sensor. Controller <NUM> can receive a signal, such as a voltage or a current, from proximity sensor <NUM> that corresponds to the detected presence of or distance to a presented container <NUM>.

In some embodiments, controller <NUM> is configured to control or direct fluid flow from dispenser conduit <NUM> based on container size (e.g., as determined from one or more signals received from proximity sensor <NUM>). For instance, controller <NUM> can determine a container distance D1 for the (e.g., vertical length) between proximity sensor <NUM> and an uppermost portion of container <NUM>. Controller <NUM> can further determine a horizontal width D2 (e.g., diameter in the lateral direction L-<FIG>) for the uppermost portion or lip of container <NUM>. A water level D3 may further be determined for a vertical length between proximity sensor <NUM> and an uppermost portion of fluid within container <NUM>. In some such embodiments, controller <NUM> is configured to automatically move multi-path valve <NUM> to the first position only if the horizontal width D2 is greater than a predetermined threshold width. If the horizontal width D2 is less than or equal to the predetermined threshold, controller <NUM> may limit fluid flow from dispenser conduit <NUM> to the second fluid flow path <NUM> (<FIG>) (e.g., by maintaining multi-path valve <NUM> in the second position during liquid dispensing operations).

Additionally or alternatively, controller <NUM> can be configured to fill a container <NUM> to a preset fluid level D3 (e.g., upon receiving a dispensing signal from user interface <NUM> or actuating mechanism <NUM>-<FIG>). As fluid (e.g., water) is dispensed from dispenser conduit <NUM>, controller <NUM> may receive multiple signals from proximity sensor <NUM> (e.g., initiated at a predetermined interval) to track the height of fluid as it rises within container <NUM>. Once the fluid level D3 reaches a set height D4 (e.g., measured as container distance D1 plus a predetermined height value), controller <NUM> may halt the flow of fluid to container <NUM> (e.g., by closing or halting flow through multi-path valve <NUM> or pressure-regulator valve).

Optionally, controller <NUM> can be configured to further control any other suitable characteristics of the fluid flow from dispenser conduit <NUM> based on one or more signals received from proximity sensor <NUM>. For instance, controller <NUM> may control the temperature of dispensed fluid based on the size or type of container <NUM> positioned within dispenser recess <NUM>. In some such embodiments, controller <NUM> is configured to selectively control the ratio of fluid from multiple sources (e.g., the ratio of water from a hot water source <NUM> and a cold water source <NUM>) that is dispensed from multi-path valve <NUM>. Optionally, one or more mixing valves may be provided upstream from dispenser conduit <NUM> (e.g., and downstream from water sources <NUM>, <NUM>) and operably coupled to controller <NUM> to selectively control, for instance, the ratio of hot water to cold water dispensed through the flow paths <NUM>, <NUM>.

In further additional or alternative embodiments, one or more light sources <NUM> are operably coupled to controller <NUM> and directed toward dispenser recess <NUM>, as shown in <FIG> and <FIG>. For instance, light source(s) <NUM> may be mounted on dispenser conduit <NUM> such that a container <NUM> within recess <NUM> is positioned below light source(s) <NUM>. In some such embodiments, light source(s) <NUM> are directed toward the fluid flow path(s) <NUM>, <NUM> exiting from dispenser conduit <NUM>.

Generally, light source <NUM> may be any suitable device or bulb for projecting visible light to dispenser recess <NUM> (e.g., illuminate a fluid flow exiting dispenser conduit <NUM> through the fluid outlets <NUM>, <NUM>). For instance, light source <NUM> may include one or more light emitting diodes (LEDs). Optionally, the LEDs or light source <NUM> may be configured to illuminate the fluid flow from dispenser conduit <NUM> as one or more colors. In such embodiments, it may be desirable to select the color in which the fluid flow is to be illuminated based on temperature of the liquid(s) being dispensed. Controller <NUM> may be configured to direct a color of the light source <NUM>. In particular, the directed color may be based on the fluid flow temperature (e.g., whether the fluid flow from the fluid source corresponds to a hot water source <NUM> or a cold water source <NUM>). As an example, in exemplary embodiments, controller <NUM> is configured to direct light source <NUM> to illuminate as a blue color to indicate to indicate the cooler temperature of the liquid being dispensed flows from the cold water source <NUM>. As an additional or alternative example, in exemplary embodiments, controller <NUM> is configured to direct light source <NUM> to illuminate as a red color to indicate to indicate the warmer temperature of the liquid being dispensed flows from the hot water source <NUM>.

Additionally, it should be appreciated that, in certain embodiments, the light source(s) <NUM> described herein may be configured to illuminate the dispenser recess <NUM> continuously (e.g., as directed by controller <NUM>). Alternatively, the light source(s) <NUM> may only be configured to illuminate during certain times or based on certain trigger events (e.g., as directed by controller <NUM>). As an example, the light source <NUM> may be configured to direct light towards the dispenser recess <NUM> only as liquid flows from dispenser conduit <NUM>.

Optionally, controller <NUM> can be configured to further control any other suitable characteristics of the illumination from light sources <NUM> based on one or more signals received from proximity sensor <NUM>. For instance, controller <NUM> may be configured to direct light source <NUM> to illuminate in multiple discrete colors based on the size or type of container <NUM> positioned within dispenser recess <NUM>. In some such embodiments, controller is configured to direct light source <NUM> to illuminate as a first color when one size or type of container <NUM> is detected through proximity sensor <NUM>, and illuminate a second discrete or unique color when another size or type of container <NUM> is detected through proximity sensor <NUM>.

Advantageously, exemplary embodiments may provide easily-viewed information relating to the flow of liquid at the location of the flow.

Turning now to <FIG>, various views are provided of a conduit portion (e.g., bottom portion <NUM>) for a dispenser conduit <NUM> according to examples not part of the invention.

As illustrated, dispenser conduit <NUM> includes a chute wall <NUM> that defines at least a portion of ice passage <NUM> along an axial direction A (e.g., parallel to the vertical direction V when assembled). For instance, outlet <NUM> may be defined along the axial direction A. Ice dispensed from dispenser conduit <NUM> may thus generally exit along the axial direction A. A radial direction R may extend outward (e.g., perpendicular to) the axial direction A.

In some examples, a separate first fluid inlet <NUM> and second fluid inlet <NUM> are defined through a portion of a chute wall <NUM>. Both fluid inlets <NUM>, <NUM> may be defined in fluid communication with one or more common water sources (e.g., <NUM>, <NUM>-<FIG>) and one or more respective downstream fluid outlets <NUM>, <NUM>. The first fluid path <NUM> (<FIG>) may be defined (at least in part) between a first fluid inlet <NUM> and first fluid outlet(s) <NUM> downstream therefrom. The second flow path <NUM> (<FIG>) may be defined (at least in part) between the second fluid inlet <NUM> and the second fluid outlet(s) <NUM> downstream therefrom. When assembled, each of the fluid inlets <NUM>, <NUM> may be defined in fluid parallel to each other.

In certain examples, a first fluid inlet <NUM> is defined on chute wall <NUM> in fluid isolation from ice passage <NUM>-e.g., downstream from fluid source(s) <NUM>, <NUM> (<FIG>), as discussed above. First fluid inlet <NUM> may be positioned radially outward from the ice passage <NUM> or axial direction A. Moreover, first fluid inlet <NUM> may be positioned above outlet <NUM> or first fluid outlets <NUM>. Additionally or alternatively, first fluid inlet <NUM> may be positioned at a front portion of chute wall <NUM>.

A first manifold channel <NUM> is defined downstream from first fluid inlet <NUM> (i.e., in downstream fluid communication with first fluid inlet <NUM>). In particular, first manifold channel <NUM> may be defined to extend within chute wall <NUM> between an internal radial partition <NUM> and an external radial partition <NUM>. Internal radial partition <NUM> may be positioned between ice passage <NUM> and first manifold channel <NUM> along the radial direction R, while external radial partition <NUM> is positioned between first manifold channel <NUM> and the ambient environment (e.g., in front of dispenser conduit <NUM>) along the radial direction R. As shown, first manifold channel <NUM> extends (at least partially) about ice passage <NUM>. In the exemplary embodiments of <FIG>, first manifold channel <NUM> is formed as a U-shaped fluid passage disposed, for example, perpendicular to the axial direction A. Optionally, a mid-point or vertex of the shaped "U" may be positioned in front of ice passage <NUM>. In some such embodiments, a solid rear wall segment <NUM> of chute wall <NUM> extends between the end points of the shaped "U" and encloses ice passage <NUM> (e.g., at a rearmost portion thereof). First fluid inlet <NUM> may generally extend to first manifold parallel to the axial direction A and intersect first manifold channel <NUM>. In the illustrated embodiments of <FIG>, first fluid inlet <NUM> intersects first manifold channel <NUM> at a mid-point or vertex of the shaped "U.

In the examples of <FIG>, a plurality of discrete first fluid outlets <NUM> are defined through chute wall <NUM>. Each first fluid outlet <NUM> may be downstream from first manifold channel <NUM> (i.e., in downstream fluid communication with first manifold channel <NUM> and first fluid inlet <NUM>). Moreover, although the first fluid outlets <NUM> need not be in perfect geometric parallel to the axial direction A, each first fluid outlet <NUM> may generally extend along the axial direction A from first manifold channel <NUM> to a bottom lip <NUM> of chute wall <NUM>. Optionally, the first fluid outlets <NUM> may be directed radially inward (e.g., at a non-parallel angle) toward axial direction A such that liquid flowing from the first fluid outlets <NUM> can converge at a location along the axial direction A that is below chute wall <NUM>. In certain embodiments, the discrete first fluid outlets <NUM> are circumferentially spaced apart along first manifold channel <NUM>. In other words, each discrete first fluid outlet <NUM> intersects first manifold channel <NUM> at a separate circumferential location of first manifold channel <NUM>. Moreover, each first fluid outlet <NUM> may be defined in fluid parallel to the other first fluid outlets <NUM>. During use, a liquid (e.g., water) may thus be selectively flowed through first fluid inlet <NUM> to first manifold channel <NUM>. Within first manifold channel <NUM>, some of the liquid may be flowed circumferentially and, thus, to each of the first fluid outlets <NUM>. From the first fluid outlets <NUM>, the liquid may be dispensed to the dispenser recess <NUM>.

In some examples, a second fluid inlet <NUM> is defined on chute wall <NUM> in fluid isolation from ice passage <NUM>-e.g., downstream from fluid source(s) <NUM>, <NUM> (<FIG>), as discussed above. Second fluid outlet <NUM> may further be defined in fluid parallel to first fluid inlet <NUM>. Second fluid inlet <NUM> may be positioned radially outward from the ice passage <NUM> or axial direction A (e.g., adjacent to or spaced apart from first fluid inlet <NUM>). Moreover, second fluid inlet <NUM> may be positioned above outlet <NUM> or a second fluid outlet <NUM>. Additionally or alternatively, second fluid inlet <NUM> may be positioned at a front portion of chute wall <NUM>.

In the examples of <FIG>, a single second fluid outlet <NUM> is defined through chute wall <NUM>. Second fluid outlet <NUM> is defined downstream from second fluid inlet <NUM> (i.e., in downstream fluid communication with second fluid inlet <NUM>). Moreover, second fluid outlet <NUM> may be in fluid isolation or fluid parallel to the first fluid outlets <NUM> and first manifold channel <NUM>. Optionally, a secondary wall <NUM> may extend from second fluid inlet <NUM> to second fluid outlet <NUM> and through first manifold channel <NUM> (e.g., at a front portion of chute wall <NUM>), such that liquids from second fluid inlet <NUM> do not pass to first manifold channel <NUM>. Although second fluid outlet <NUM> need not be in perfect geometric parallel to the axial direction A, second fluid outlet <NUM> may generally extend along the axial direction A at a bottom lip <NUM> of chute wall <NUM>. In certain embodiments, the second fluid outlet <NUM> is defined through chute wall <NUM> at a front portion thereof. During use, a liquid (e.g., water) may thus be selectively flowed through second fluid inlet <NUM> to second fluid outlet <NUM>, from which the liquid may be dispensed to the dispenser recess <NUM>.

In examples, one or more fluidly-isolated compartments <NUM> are defined within chute wall <NUM> to receive a light source <NUM> or proximity sensor <NUM> (<FIG>). For instance, the compartments <NUM> may be defined at a bottom lip <NUM> of chute wall <NUM> separate from fluid outlets <NUM>, <NUM> and ice passage <NUM> (e.g., such that liquids or ice are not directed therethrough). One or more proximity sensors <NUM> or light sources <NUM> may be mounted within chute wall <NUM> and received within a fluidly-isolated compartment <NUM>. When mounted, the proximity sensor <NUM> or light source <NUM> may be directed toward dispenser recess <NUM> (<FIG>). In certain embodiments, a plurality of fluidly-isolated compartments <NUM> is defined within chute wall <NUM>. As shown, each of the fluidly-isolated compartments <NUM> is spaced apart (e.g., circumferentially) from each other about the axial direction A or ice passage <NUM>.

As described above, a multi-path valve <NUM> (<FIG>) may be positioned in upstream fluid communication with the plurality of discrete first fluid outlets <NUM> and the second fluid outlet <NUM> (e.g., within a refrigerator door upstream from the fluid inlets <NUM>, <NUM>). A liquid may be selectively flowed through the first fluid path <NUM> or the second fluid path <NUM> (<FIG>). During use, the multi-path valve <NUM> may thus alternately direct the fluid flow from the fluid source to the first plurality of discrete fluid outlets <NUM>, <NUM> and the second fluid outlet <NUM>.

Turning now to <FIG> and <FIG>, various views are provided of a conduit portion (e.g., bottom portion <NUM>) for a dispenser conduit <NUM> according to examples not part of the invention.

For instance, although certain above-described embodiments describe multi-path valve <NUM> generally, the examples of <FIG> and <FIG> illustrate an exemplary switch valve for multi-path valve <NUM>. Generally, multi-path valve <NUM> may be moved to alternately direct the fluid flow from the fluid source(s) (<FIG>) to first fluid outlets <NUM> and second fluid outlet <NUM>. For instance, multi-path valve <NUM> may be moved manually by a user or, alternatively, automatically by a mechanically-coupled electronic motor that is operably coupled to controller <NUM> (<FIG>).

As shown, multi-path valve <NUM> may include a slidable plate <NUM> defining a first-path passage <NUM> and a second-path passage <NUM>. Each of the first-path passage <NUM> and second-path passage <NUM> may be spaced apart from each other (e.g., in the lateral direction L or the transverse direction T). Slidable plate <NUM> may be mounted within a plate cavity <NUM> defined in chute wall <NUM> (e.g., at a front portion thereof). For instance, plate cavity <NUM> may be defined between the fluid inlets <NUM>, <NUM> and the fluid outlets <NUM>, <NUM> (e.g., along the vertical direction V). Moreover, plate cavity <NUM> may generally be provided within an excess length or width to permit slidable plate <NUM> to move (e.g., slide along the lateral direction L) within plate cavity <NUM> between a first position and a second position.

In the first position, first-path passage <NUM> may be axially-aligned with first fluid inlet <NUM>, thereby permitting liquid from first fluid inlet <NUM> to first cavity manifold <NUM> (e.g., <FIG>) and first fluid outlets <NUM>. Second-path passage <NUM> may be offset from second fluid inlet <NUM> (e.g., a solid non-permeable portion of slidable plate <NUM> may be axially aligned with the second fluid inlet <NUM>), thereby restricting or preventing liquid from second fluid inlet <NUM>. In the second position (e.g., illustrated at <FIG>), second-path passage <NUM> may be axially-aligned with second fluid inlet <NUM>, thereby permitting liquid from second fluid inlet <NUM> to second fluid outlet <NUM>. First-path passage <NUM> may be offset from first fluid inlet <NUM> (e.g., a solid non-permeable portion of slidable plate <NUM> may be axially aligned with the first fluid inlet <NUM>), thereby restricting or preventing liquid from first fluid inlet <NUM>.

Turning now to <FIG>, various views are provided of a conduit portion (e.g., bottom portion <NUM>) for a dispenser conduit <NUM> according to embodiments of the invention.

In some embodiments, a first manifold channel <NUM> is defined downstream from first fluid inlet <NUM> (i.e., in downstream fluid communication with first fluid inlet <NUM>). In particular, first manifold channel <NUM> may be defined to extend within chute wall <NUM> between an internal radial partition <NUM> and an intermediate radial partition <NUM>. Internal radial partition <NUM> may be positioned between ice passage <NUM> and first manifold channel <NUM> along the radial direction R while intermediate radial partition <NUM> is radially spaced apart (e.g., outward along the radial direction R) from internal radial partition <NUM> (e.g., in front of first manifold channel <NUM>) along the radial direction R. As shown, first manifold channel <NUM> extends (at least partially) about ice passage <NUM>. In the exemplary embodiments of <FIG>, first manifold channel <NUM> is formed as a U-shaped fluid passage disposed, for example, perpendicular to the axial direction A. Optionally, a mid-point or vertex of the shaped "U" may be positioned in front of ice passage <NUM>. In some such embodiments, a solid rear wall segment <NUM> of chute wall <NUM> extends between the end points of the shaped "U" and encloses ice passage <NUM> (e.g., at a rearmost portion thereof). First fluid inlet <NUM> may generally extend to first manifold parallel to the axial direction A and intersect first manifold channel <NUM>. In the illustrated embodiments of <FIG>, first fluid inlet <NUM> intersects first manifold channel <NUM> at a mid-point or vertex of the shaped "U.

In the exemplary embodiments of <FIG>, a plurality of discrete first fluid outlets <NUM> are defined through chute wall <NUM>. Each first fluid outlet <NUM> may be downstream from first manifold channel <NUM> (i.e., in downstream fluid communication with first manifold channel <NUM> and first fluid inlet <NUM>). Moreover, although the first fluid outlets <NUM> need not be in perfect geometric parallel to the axial direction A, each first fluid outlet <NUM> may generally extend along the axial direction A from first manifold channel <NUM> to a bottom lip <NUM> of chute wall <NUM>. Optionally, the first fluid outlets <NUM> may be directed radially inward (e.g., at a non-parallel angle) toward axial direction A such that liquid flowing from the first fluid outlets <NUM> can converge at a location along the axial direction A that is below chute wall <NUM>. In certain embodiments, the discrete first fluid outlets <NUM> are circumferentially spaced apart along first manifold channel <NUM>. In other words, each discrete first fluid outlet <NUM> intersects first manifold channel <NUM> at a separate circumferential location of first manifold channel <NUM>. Moreover, each first fluid outlet <NUM> may be defined in fluid parallel to the other first fluid outlets <NUM>. During use, a liquid (e.g., water) may thus be selectively flowed through first fluid inlet <NUM> to first manifold channel <NUM>. Within first manifold channel <NUM>, some of the liquid may be flowed circumferentially and, thus, to each of the first fluid outlets <NUM>. From the first fluid outlets <NUM>, the liquid may be dispensed to the dispenser recess <NUM>.

In some embodiments, a second fluid inlet <NUM> is defined on chute wall <NUM> in fluid isolation from ice passage <NUM>-e.g., downstream from fluid source(s) <NUM>, <NUM> (<FIG>), as discussed above. Second fluid outlet <NUM> may further be defined in fluid parallel to first fluid inlet <NUM>. Second fluid inlet <NUM> may be positioned radially outward from the ice passage <NUM> or axial direction A (e.g., adjacent to or spaced apart from first fluid inlet <NUM>). Moreover, second fluid inlet <NUM> may be positioned above outlet <NUM> or a second fluid outlet <NUM>. Additionally or alternatively, second fluid inlet <NUM> may be positioned at a front portion of chute wall <NUM>.

In the exemplary embodiments of <FIG>, a second manifold channel <NUM> is defined downstream from second fluid inlet <NUM> (i.e., in downstream fluid communication with second fluid inlet <NUM>). In particular, second manifold channel <NUM> may be defined to extend within chute wall <NUM> between intermediate radial partition <NUM> and an external radial partition <NUM>. Intermediate radial partition <NUM> may be positioned between second manifold channel <NUM> and first manifold channel <NUM> along the radial direction R while external radial partition <NUM> is positioned between second manifold channel <NUM> and the ambient environment (e.g., in front of dispenser conduit <NUM>) along the radial direction R. As shown, second manifold channel <NUM> extends (at least partially) about ice passage <NUM>. In the exemplary embodiments of <FIG>, second manifold channel <NUM> is formed as a U-shaped fluid passage disposed, for example, perpendicular to the axial direction A. Optionally, second manifold channel <NUM> may be defined parallel to first manifold channel <NUM>. Additional or alternatively, a mid-point or vertex of the shaped "U" may be positioned in front of ice passage <NUM> or first manifold channel <NUM>. Second fluid inlet <NUM> may generally extend to second manifold parallel to the axial direction A and intersect second manifold channel <NUM>. In the illustrated embodiments of <FIG>, second fluid inlet <NUM> intersects second manifold channel <NUM> at a mid-point or vertex of the shaped "U.

In certain embodiments, a plurality of discrete second fluid outlets <NUM> is defined through chute wall <NUM>. Each second fluid outlet <NUM> may be downstream from second manifold channel <NUM> (i.e., in downstream fluid communication with second manifold channel <NUM> and second fluid inlet <NUM>). Moreover, although the second fluid outlets <NUM> need not be in perfect geometric parallel to the axial direction A, each second fluid outlet <NUM> may generally extend along the axial direction A from second manifold channel <NUM> to a bottom lip <NUM> of chute wall <NUM>. Optionally, the second fluid outlets <NUM> may be directed radially inward (e.g., at a non-parallel angle) toward the axial direction A such that liquid flowing from the second fluid outlets <NUM> can converge at a location along the axial direction A that is below chute wall <NUM>. In certain embodiments, the discrete second fluid outlets <NUM> are circumferentially spaced apart along second manifold channel <NUM>. In other words, each discrete second fluid outlet <NUM> intersects second manifold channel <NUM> at a separate circumferential location of second manifold channel <NUM>. Moreover, each second fluid outlet <NUM> may be defined in fluid parallel to the other second fluid outlets <NUM>. During use, a liquid (e.g., water) may thus be selectively flowed through second fluid inlet <NUM> to second manifold channel <NUM>. Within second manifold channel <NUM>, some of the liquid may be flowed circumferentially and, thus, to each of the second fluid outlets <NUM>. From the second fluid outlets <NUM>, the liquid may be dispensed to the dispenser recess <NUM>.

In certain embodiments, one or more fluidly-isolated compartments <NUM> are defined within chute wall <NUM> to receive a light source <NUM> or proximity sensor <NUM> (<FIG>). For instance, the compartments may be defined at a bottom lip <NUM> of chute wall <NUM> separate from fluid outlets <NUM>, <NUM> and ice passage <NUM> (e.g., such that liquids or ice are not directed therethrough). One or more proximity sensors <NUM> or light sources <NUM> may be mounted within chute wall <NUM> (e.g., at a front portion thereof) and received within a fluidly-isolated compartment <NUM>. When mounted, the proximity sensor <NUM> or light source <NUM> may be directed toward dispenser recess <NUM> (<FIG>). In certain embodiments, a plurality of fluidly-isolated compartments <NUM> is defined within chute wall <NUM>. As shown, each of the fluidly-isolated compartments <NUM> is spaced apart (e.g., circumferentially) from each other about the axial direction A or ice passage <NUM>.

As described above, a multi-path valve <NUM> (<FIG>) may be positioned in upstream fluid communication with the plurality of discrete first fluid outlets <NUM> and the second fluid outlets <NUM> (e.g., within a refrigerator door upstream from the fluid inlets <NUM>, <NUM>). A liquid may be selectively flowed through the first fluid path <NUM> or the second fluid path <NUM> (<FIG>). During use, the multi-path valve <NUM> may thus alternately direct the fluid flow from the fluid source to the plurality of discrete first fluid outlets <NUM> and the plurality of discrete second fluid outlets <NUM>.

In some examples, dispenser conduit <NUM> includes a bottom portion <NUM> that is provided as multiple discrete segments. For instance, chute wall <NUM> of the bottom portion <NUM> may include at least two discrete segments. A top segment <NUM> may extend along ice passage <NUM> from upper portion <NUM> (<FIG>) while a lower segment <NUM> is joined to top segment <NUM> (e.g., in a bottom end thereof via one or more suitable adhesives, ultrasonic welds, or mechanical fasteners). In some such embodiments, a first manifold channel <NUM> is defined within lower segment <NUM>. Optionally, first manifold channel <NUM> extends about the entirety of ice passage <NUM> (e.g., perpendicular to the axial direction A). Thus, first manifold channel <NUM> may be provided as a continuous fluid channel surrounding ice passage <NUM>. Additionally or alternatively, first fluid inlet <NUM> may be provided as a generally axial passage defined through top segment <NUM>.

In certain examples, a plurality of discrete first fluid outlets <NUM> is defined through lower segment <NUM>. Each first fluid outlet <NUM> may be downstream from first manifold channel <NUM> (i.e., in downstream fluid communication with first manifold channel <NUM> and first fluid inlet <NUM>). Moreover, although the first fluid outlets <NUM> need not be in perfect geometric parallel to the axial direction A, each first fluid outlet <NUM> may generally extend along the axial direction A from first manifold channel <NUM> to a bottom lip <NUM> of chute wall <NUM>. Optionally, the first fluid outlets <NUM> may be directed radially inward (e.g., at a non-parallel angle) toward axial direction A such that liquid flowing from the first fluid outlets <NUM> can converge at a location along the axial direction A that is below chute wall <NUM>. In certain embodiments, the discrete first fluid outlets <NUM> are circumferentially spaced apart along first manifold channel <NUM>. In other words, each discrete first fluid outlet <NUM> intersects first manifold channel <NUM> at a separate circumferential location of first manifold channel <NUM>. Moreover, each first fluid outlet <NUM> may be defined in fluid parallel to the other first fluid outlets <NUM>. During use, a liquid (e.g., water) may thus be selectively flowed through first fluid inlet <NUM> to first manifold channel <NUM>. Within first manifold channel <NUM>, some of the liquid may be flowed circumferentially and, thus, to each of the first fluid outlets <NUM>. From the first fluid outlets <NUM>, the liquid may be dispensed to the dispenser recess <NUM>.

In additional or alternative examples, channel cap <NUM> is provided on lower segment <NUM>. Channel cap <NUM> may be positioned over first manifold channel <NUM> (e.g., between first fluid inlet <NUM> and first manifold channel <NUM> along the axial direction A). Moreover, channel cap <NUM> may extend along first manifold channel <NUM> and about ice passage <NUM> such that channel cap <NUM> covers first manifold channel <NUM>. Thus, when assembled channel cap <NUM> may prevent liquid from flowing above and out of first manifold channel <NUM>.
