DETAILED DESCRIPTION
(20) Turning now to the drawings, wherein like numbers denote like parts throughout the several views,
(21) Fresh food compartment 14 is generally maintained at a temperature above freezing for storing fresh food such as produce, drinks, eggs, condiments, lunchmeat, cheese, etc. Various shelves, drawers, and/or sub-compartments may be provided within fresh food compartment 14 for organizing foods, and it will be appreciated that some refrigerator designs may incorporate multiple fresh food compartments and/or zones that are maintained at different temperatures and/or at different humidity levels to optimize environmental conditions for different types of foods. Freezer compartment 16 is generally maintained at a temperature below freezing for longer-term storage of frozen foods, and may also include various shelves, drawers, and/or sub-compartments for organizing foods therein.
(22) Refrigerator 10 as illustrated in
(23) Refrigerator 10 also includes a cabinet-mounted dispenser 26 for dispensing ice and/or water. In the illustrated embodiments, dispenser 26 is an ice and water dispenser capable of dispensing both ice and chilled water, while in other embodiments, dispenser 26 may be an ice only dispenser for dispensing only cubed and/or crushed ice. In still other embodiments, dispenser 26 may additionally dispense hot water, coffee, beverages, or other liquids, and may have variable and/or fast dispense capabilities. In some instances, ice and water may be dispensed from the same location, while in other instances separate locations may be provided in the dispenser for dispensing ice and water.
(24) A refrigerator consistent with the invention also generally includes one or more controllers configured to control a refrigeration system as well as manage interaction with a user.
(25) As shown in
(26) Controller 40 may also be interfaced with various sensors 56 located to sense environmental conditions inside of and/or external to refrigerator 10, e.g., one or more temperature sensors, humidity sensors, etc. Such sensors may be internal or external to refrigerator 10, and may be coupled wirelessly to controller 40 in some embodiments. Sensors 56 may also include additional types of sensors such as door switches, switches that sense when a portion of an ice dispenser has been removed, and other status sensors, as will become more apparent below.
(27) In some embodiments, controller 40 may also be coupled to one or more network interfaces 58, e.g., for interfacing with external devices via wired and/or wireless networks such as Ethernet, Wi-Fi, Bluetooth, NFC, cellular and other suitable networks, collectively represented in
(28) In some embodiments, refrigerator 10 may be interfaced with one or more user devices 62 over network 60, e.g., computers, tablets, smart phones, wearable devices, etc., and through which refrigerator 10 may be controlled and/or refrigerator 10 may provide user feedback.

In addition, it will be appreciated that the various operations described herein may be combined, split, reordered, reversed, varied, omitted, parallelized and/or supplemented with other techniques known in the art, and therefore, the invention is not limited to the particular sequences of operations described herein.
(30) Numerous variations and modifications to the refrigerator illustrated in
Icemaking Console
(31) Now turning to
(32) Console 70 may extend in some instances to a back wall 96 of fresh food compartment 14, while in other instances, and as shown in
(33) Moreover, the walls 82, 84, 86 and 88 of console 70 may be insulated (e.g., via foam or another suitable insulator) such that console 70 is an insulated console and such that an interior compartment of console 70 is maintained at a below-freezing temperature for the purposes of making and storing ice. In the illustrated embodiment, console 70 is in fluid communication with freezer compartment 16 through an opening 100 formed in bottom wall 72 of fresh food compartment 14, such that while console 70 is physically disposed within the boundary of fresh food compartment 14, the interior of console 70 is insulated from the fresh food compartment and in fluid communication with freezer compartment 16, thus effectively operating as an extension of freezer compartment 16. In other embodiments, console 70 may be separate from freezer compartment 16, e.g., insulated from freezer compartment 16 and including a separate cooling system, e.g., a thermoelectric cooling system, or separated from freezer compartment 16 but fluidly coupled via ducts or vents to receive cool air circulated by the freezer compartment cooling system.
(34) Further, it will be appreciated that console 70 is formed separate from the shell or liner used to form the fresh food and/or freezer compartments. In other embodiments, however, console 70 may be formed integrally with the shell or liner of a fresh food and/or freezer compartment.
(35) Console 70 in some embodiments may also provide a convenient location for a control panel 102 suitable for controlling various functions of refrigerator 10. For example, control panel 102 may include displays, buttons, sliders, switches, etc., and may be used to perform various control operations such as setting temperature setpoints, controlling ice and/or water functions, displaying alarms or alerts, etc. As shown in the illustrated embodiment, top wall 84 of console 70 may be bi-level to accommodate control panel 102, although in other embodiments, no control panel may be used, and top wall 84 may be at a substantially consistent elevation along its depth.
(36) Console 70 in some instances may be an icemaking console insofar as the console is used to make, dispense and/or store ice. As will become more apparent below, however, console 70 may not be an icemaking console in some embodiments. In some embodiments, however, console 70 may be configured to receive one or more drawers or storage bins, e.g., upper and lower ice storage bins 104, 106. Upper ice storage bin 104 includes a front face 108 that insulates console 70 from the external environment when the bin is pushed into the console and forms a front surface of the upper ice storage bin, while lower ice storage bin 106 includes a front face 110 that similarly insulates console 70 from the external environment when the bin is pushed into the console and forms a front surface of the lower ice storage bin. Front faces 108, 110 also house at least a portion of an externally-accessible ice and water dispenser, discussed in greater detail below. In some embodiments, a single front face may be used, whereby the upper and lower ice storage bins may be coupled to the same front face.
(37) Beyond ice-related functions, however, console 70 also provides a number of structural features associated with the storage of food items within fresh food compartment 14. For example, as illustrated in
(38) Storage elements 112 and 118, for example, are sliding shelves, while storage elements 114, 116, 120 and 122 are sliding storage bins or drawers. It will also be appreciated that storage bins or drawers may be configured with customizable environmental conditions (e.g., different temperatures, humidity levels, etc.) suitable for storing food items such as meats, cheeses, vegetables, fruits, etc. Further, not all of storage elements 114-122 need be configured as sliding storage elements, and moreover, different numbers and types of storage elements may be used for any of the storage elements illustrated in
(39) Moreover, despite the fact that storage elements 112-122 are disposed within a full width fresh food compartment 14, console 70 provides greater support for these storage elements, so much so that in some embodiments it may be desirable to utilize full extension slide rails (e.g., slide rails 124, 126 for storage element 120) to support a sliding storage element, permitting the sliding storage element to be fully extended outwardly from the fresh food compartment, thereby providing greater access to the rear portion of the interior of a storage bin, drawer or basket, or to the rear portion of a shelf or rack. A full extension slide rail, in this regard, is configured to extend at least substantially the full depth of a sliding storage element, including overextension beyond the full depth of the sliding storage element in some embodiments.
(40) Likewise, and with further reference to
(41) In the illustrated embodiment, in contrast, top wall 84 of console 70 may provide adequate support for full width shelf 128 to enable a full width shelf to substantially span the entire width of fresh food compartment 14. In one embodiment illustrated in
(42) Other manners of supporting full width shelf 128 may be used in other embodiments, including various combinations of undermount, top mount or side mount slide rails, glides (i.e., low friction tracks or surfaces), etc.
(43) As noted above, in the illustrated embodiment of
(44) As shown in
(45) As shown in
(46) As shown in
(47) Other variations will be appreciated by those of ordinary skill in the art having the benefit of the instant disclosure. Therefore, the invention is not limited to the particular console designs described herein.
Icemaking System
(48) Now turning to
(49) Upper ice storage bin 104 also includes a reversible ice mover 224. Ice mover 224 may be driven by a motor 226 or other drive, which in the illustrated embodiment is external to upper ice storage bin 104 and removably and mechanically coupled to ice mover 224 to drive ice mover 224 in two opposing directions when upper ice storage bin 104 is in an operating position, but to separate from the upper ice storage bin when the upper ice storage bin is slid outwardly from console 70. In other embodiments, an ice mover drive may be incorporated into upper ice storage bin 104 itself, and may be removable from refrigerator 10 along with the upper ice storage bin.
(50) Ice mover 224 in the illustrated embodiment may be configured as an auger. In other embodiments, however, ice mover 224 may be configured as a conveyor, a paddle, or other suitable component. Moreover, while no ice crusher is specifically illustrated in the figures, it will be appreciated that various types of ice crusher configurations may be used, and may provide selective crushing of ice dispensed by the icemaking system.
(51) As noted above, ice mover 224 is reversible, and in this regard, may be actuated to push ice disposed in upper ice storage bin 104 in two opposing directions. In a first, forward direction, ice mover 224 pushes ice towards an ice dispenser 228, which in the illustrated embodiment includes portions disposed on each of the front faces 108, 110 of upper and lower ice storage bins 104, 106. Specifically, ice mover 224 may be configured to push ice towards the front of refrigerator 10, and towards an ice chute 230 disposed in front face 108 of the upper ice storage bin. Doing so causes ice (cubed or crushed) to fall through the ice chute and into a container positioned within a dispenser recess portion 232 defined on front face 110 of lower ice storage bin 106. In some embodiments, a flap 234 or other closure may also be provided proximate ice chute 230 to provide some insulation for the ice chute and reduce heat loss from icemaking console 70.
(52) In a second, rearward direction, ice mover 224 pushes ice away from ice dispenser 228, and towards a rearwardly-disposed aperture 236 formed in upper ice storage bin at an opposite end from ice dispenser 228 such that ice pushed into aperture 236 drops into lower ice storage bin 106 positioned below upper ice storage bin 104. While aperture 236 is illustrated as being formed in a bottom wall of upper ice storage bin 104, aperture 236 may alternatively be disposed elsewhere, e.g., on an end or side wall of upper ice storage bin 104. Moreover, while aperture 236 is illustrated as being always open, in other embodiments a movable closure element such as a hinged or sliding trap door may be used, e.g., so that aperture 236 is closed when upper ice storage bin 104 is removed from icemaking console 70. For example, in some embodiments aperture may be normally closed but opened when ice mover 224 is pushing ice in the second, rearward direction.
(53) Lower ice storage bin 106 in the embodiment illustrated in
(54) Returning to
(55) In one example embodiment, for example, lower ice storage bin 106 may be used as a primary ice storage bin from which a user may obtain ice when a large quantity of ice is needed by the user. The lower ice storage bin 106 may lack a stop and thus may be easily removed from icemaking console 70, even when doors 18, 20, 22 and 24 are all closed. Upper ice storage bin 104, in contrast, may be primarily used to hold ice for dispensing purposes, and thus may not be frequently removed from icemaking console 70 by a user. The upper ice storage bin, however, also provides access to ice mover 224 and icemaker 220, and thus in the event of an obstruction or other issue that may inhibit the production, dispensing and/or storage of ice, the upper ice storage bin may be removed to enable a user to clear any obstructions. In this regard, upper ice storage bin 104 may include stop 244 such that it is not fully removed by a user in most circumstances, yet is still fully removable through actuation of stop 244, e.g., for use by service personnel or when wider access to the upper area of the icemaking console is needed or desired.
(56) Each of upper and lower ice storage bins 104, 106 may be configured to be slidably removed from icemaking console 70, either with or without the use of slide rails or other tracking guides. In the embodiment of
(57) In addition, as discussed above, housing 98 in some embodiments provides additional space within fresh food compartment, e.g., for a fresh food, freezer, or other evaporator, a fan, a compressor, or other cooling system component, for control electronics, or for other purposes. The interior of housing 98 may insulated from fresh food compartment in some embodiments, or may be in fluid communication with the fresh food compartment via vents. In other embodiments, housing 98 may be omitted, and console 70 may extend all of the way to back wall 96. In some embodiments, and as shown in dashed lines in
(58) Turning now with particular reference to
(59) In addition to ice dispenser 228, refrigerator 10 also includes a water dispenser 258 disposed on icemaking console 70. Water dispenser 258, as with ice dispenser 228, is externally-accessible when doors 18, 20, 22, and 24 are closed. Unlike ice dispenser 228, however, water dispenser 258 is disposed at a fixed location in icemaking console 70, e.g., on a cantilevered extension 260 having a profile that conforms with front face 108 of upper ice storage bin 104. Water dispenser 258 includes an outlet 262 coupled to a supply line 264, and further includes a valve (not shown) that controls the supply of water to outlet 262. A water dispenser control 266, e.g., a paddle or button, may be disposed underneath outlet 262, e.g., on front face 108 of upper ice storage bin 104, may be used to selectively actuate water dispenser 258 either through pressing by a user's finger or by pressing the edge of a container against the control.
(60) By providing at least the water supply and outlet of water dispenser 258 on a fixed component of refrigerator 10, no detachable couplings or flexible hoses are needed in order to support movement of the water dispenser relative to icemaking console 70. In addition, since at least outlet 262 of water dispenser 258 is separate from ice dispenser 228, ice storage bins 104, 106 are readily removable without concern for the water supply to water dispenser 258.
(61) It will be appreciated, however, that other dispenser configurations may be used in other embodiments. In some embodiments, for example, ice and water may be dispensed from the same dispenser recess portion, and in some instances using the same control (e.g., where a separate dispenser mode switch is used to select between ice, water, and in some instances, crushed ice). Further, different dispenser controls may be used in other embodiments, e.g., various combinations of buttons, paddles, proximity sensors, mode switches, etc. In addition, in other embodiments the various components of the ice and/or water dispensers may be disposed on removable or fixed components in refrigerator 10. Therefore, the invention is not limited to the particular configuration disclosed herein.
(62) In addition, given that controls 256, 266 are disposed on removable components (upper and lower ice storage bins 104, 106), it may be desirable in some embodiments to include a dispenser shut off circuit for one or both of the ice dispenser 228 and water dispenser 258 in response to movement of either of upper and lower ice storage bins 104, 106 away from an operating position. In some embodiments, for example, a dispenser shut off circuit may include one or more switches (e.g., contact switches, magnetic switches, etc.) that disconnect controls 256, 266 from controller 40 when an upper and/or lower ice storage bin 104, 106 is moved away from the operating position.
(63) As shown in
(64) Controller 40 may be configured to deactivate ice and/or water dispenser 228, 258 whenever one or both of upper and lower ice storage bins 104, 106 have been pulled away from icemaking console 70. For example, it may be desirable in some instances to disable both dispensers in response to either ice storage bin 104, 106 being out of an operating position.
(65) In some embodiments, control signals generated by controls 256, 266 may be passed through contact switches 270, 274 and contact pads 272, 276. In other embodiments, separate electrical contacts or wiring may be used to communicate control signals. In addition, while contact switches are illustrated as being located on surfaces that are generally transverse to the sliding axes of ice storage bins 104, 106, in other embodiments the contact switches may be disposed on surfaces that are generally parallel to the sliding axes, or in other locations suitable for detecting the presence of an ice storage bin in an operating position. Moreover, while electrical contact switches are illustrated in
(66) Control of ice production with icemaker 220 may be based in part on the sensed level of ice in each of upper and lower ice storage bins 104, 106. In some embodiments, for example, an upper level sensor 280 and a lower level sensor 282 may be configured to sense the level of ice within each of upper and lower ice storage bins 104, 106. Level sensors 280, 282 may be configured as optical or photoelectric sensors, although other sensors may be used in other embodiments, e.g., weight sensors, or sensor arrays capable of sensing ice level at multiple locations in each ice storage bin.
(67) As shown in
(68) Once the ice production process is complete and the icemaker is ready to release the ice, block 304 passes control to block 308 to determine (e.g., from sensor 280) whether the upper storage bin is full. If not, control passes to block 310 to operate ice mover 224 in the forward direction a predetermined amount to push ice forward towards dispenser 228. By pushing ice forward, the ice may be positioned proximate dispenser 228 to reduce the amount of time ice mover 224 needs to be actuated before ice is dispensed to a user. Control then passes to block 312 to release the ice, thereby dropping the ice into the upper ice storage bin 104. Control then returns to block 302 to initiate another ice production operation.
(69) Returning to block 308, if the upper storage bin is determined to be full, block 308 instead passes control to block 314 to determine (e.g., using sensor 282) whether the lower ice storage bin is full. If so, control returns to block 304 to wait until the upper storage bin is no longer full (e.g., after a user has dispensed some ice using the ice dispenser), such that the produced ice is retained in the icemaker, and no additional ice is produced, until sufficient room exists in the upper ice storage bin.
(70) Returning to block 314, if the lower storage bin is determined to not be full, block 314 passes control to block 316 to operate ice mover 224 in the opposite, rearward direction a predetermined amount to push ice rearward so that at least some of the ice will drop into lower ice storage bin 106. Block 318 then determines if the upper storage bin is still full, and if so, returns control to block 316 to continue pushing ice rearward and thus from the upper ice storage bin to the lower ice storage bin. Once the upper ice storage bin is no longer full, block 318 then passes control to block 312 to release the ice, and then to block 302 to initiate another ice production operation.
(71) As shown in the Figures, the refrigerator may include configurations to distribute ice from the upper ice storage bin to reduce the buildup of ice in a pile or mound. In some implementations, the ice dispensing system may be configured to evenly distribute ice from the upper ice storage bin to the lower ice storage bin. The lower storage bin may be a variety of sizes, shapes, quantities, constructions, and positions relative to the upper ice storage bin. In one implementation as shown in
(72) As shown in the embodiment in
(73) The apertures may be positioned along the longitudinal axis A in a variety of quantities, sizes, shapes, and positions within the upper ice storage bin. As shown in
(74) The one or more apertures may be positioned at a variety of lengths along the upper ice storage bin or longitudinal axis A. The spacing between each aperture 436, on one or both sides/periphery of the bin, may be a variety of distances D1, D2 therebetween. In some implementations, distance D1 may be larger than distance D2 as shown in
(75) The size and shape of one or more apertures 436 may be a variety of constructions along the length of the upper ice storage bin. Although the size and/or shape of the apertures 436 may be similar in some embodiments, the apertures may be different in size and/or shape along the length of the upper ice storage bin to evenly distribute the ice below. As shown in the one embodiment in
(76) The ice dispensing system may include one or more slides, guides, or deflecting plates 500 to funnel ice between the upper ice storage bin 404 to the lower ice storage bin 106. The plates 500 may disperse or scatter the ice falling in one or more directions from the upper ice storage bin 404 to one or more directions towards the lower ice storage bin 106. Although not shown, a series of plates 500 may be used to direct the ice from one or more apertures. As shown in
(77) In some implementations, the deflecting plate 500 may be positioned adjacent one or more apertures 436 of the upper ice storage bin. The deflecting plate 500 may be positioned below at least one aperture 436 or between the aperture and the lower ice storage bin. As shown in
(78) In some implementations, the ice dispensing system may include one or more raking structures or baffles 600 to guide ice one or more apertures of the upper ice storage bin 504. The raking structure 600 may be used to guide ice into or through an adjacent or downstream aperture 436, or more specifically shown in
(79) In the one embodiment shown of the raking structure, the raking structure 600 may include one or more cam surfaces. One cam surface 620 of one or more walls 610 may be inwardly and angled towards the longitudinal axis A or ice mover 224, such that the cam surface faces the ice dispenser 228. In some embodiments, the cam surface 620 may be positioned at an angle B (e.g. acute) relative to the side wall 511 adjacent or more proximal to the ice dispenser 228. The acute angle B may be in the direction opposite of the ice removal direction. The angle B may be a variety of angles and still be within the scope of the invention. When the ice is moved in the second direction (e.g. towards the end wall 510), the ice is guided or diverted along the cam surface 620 outwardly and away to the aperture 436d from the ice mover 224. The cam surface may alternatively guide ice in a variety of directions towards the aperture (e.g. inwardly) for example. The raking structure 600 may also include a second or another one or more cam surfaces 622 in some embodiments. As shown in
(80) In some implementations, the raking structure may include one or more walls or members arranged to guide the ice from the upper ice storage bin (e.g. through one or more apertures 436) when the ice mover is moving in a direction and/or pass over in the other opposing direction. As shown in the one embodiment of
(81) It should be understood that the raking structure may include a variety of sizes, shapes, quantities, constructions, and positions relative to the apertures, ice mover, and/or top edge (e.g. side wall, end walls, and/or bottom walls) and still be within the scope of the invention. For example, the raking structure may be several members in series to guide the ice in one or more directions. In some implementations, the ice may be raked within an aperture within the bin's bottom wall. In various embodiments, the raking structure may be spaced from the aperture and/or side wall. In some embodiments, the rear facing and/or front facing angled cam surfaces, if used, may be parallel to each other as shown however may not be parallel to each other in some embodiments. Moreover, varying the size, shape, quantities, construction, angles relative to the direction of ice motion, and position within the upper ice storage bin may adjust the percentage of ice grabbed/transferred through the apertures/receiving inlet along the length of the bin(s).
(82) In some implementations, the two or more apertures spaced along the length of upper ice storage bin may allow for the overflow of ice to dispense evenly to the lower ice storage bin without the ice mover moving ice in one or more directions. For example, two or more apertures may be spaced along the longitudinal axis (e.g. within one or both side walls, or in combination with a bottom wall and/or end wall aperture, etc.). The overflow may occur with or without the ice mover moving in one or more directions. For example, in some implementations, the upper ice storage bin may overflow until the lower ice bucket bin level sensor 282 and/or other sensors signal the shut off of the ice ejection or supply.

(84) It will be appreciated that various additional modifications may be made to the embodiments discussed herein, and that a number of the concepts disclosed herein may be used in combination with one another or may be used separately. For example, an icemaking console consistent with the invention may be used in connection with other icemaking systems in other embodiments, and conversely, an icemaking system consistent with the invention may be used in other refrigerator designs, including those without an icemaking console and/or those in which an icemaking system is at least partially disposed elsewhere in a fresh food compartment, a freezer compartment, or door of a refrigerator. Furthermore, an icemaking system consistent with the invention may incorporate tandem ice storage bins without a removable dispenser recess portion in some embodiments, or alternatively, a removable dispenser recess portion without tandem ice storage bins. Therefore, the invention lies in the claims hereinafter appended.
