Referring now generally to
Storage bin assembly 200 may include a bin frame 202. Bin frame 202 may rotatably support a plurality of storage bins 216 through a shaft 214 (described in detail below). Bin frame 202 may include a top frame member 204 and a bottom frame member 206. Bin frame 202 may further include a first side frame member 208 and a second side frame member 210 opposite the first side frame member 208. The first and second side frame members 208 and 210 may include features allowing storage bin assembly 200 to be removably coupled to refrigerator appliance 100. For example, side frame members 208 and 210 may include grooves formed on each respective outer surface configured to interconnect with tabs or ledges formed, for example, in door 128 of refrigerator appliance 100. One sample location of storage bin assembly 100 is shown in phantom lines in
Top frame member 204 and bottom frame member 206 may be positioned such that a single storage bin 216 is visible at one time. In other words, top frame member 204 and bottom frame member 206 may collectively define a slot 212 through which storage bin 216 is accessible. Accordingly, in some embodiments, top frame member 204 and bottom frame member 206 are a single integral piece. In some embodiments, top frame member 204 is a separate piece from bottom frame member 206. In such an example, top frame member 204 and bottom frame member 206 may be fastened together (e.g., at a rear side of bin frame 202 opposite slot 212). For example, top frame member 204 and bottom frame member 206 may be fastened together via a bolt or screw, a snap fit, an adhesive, or the like. First side frame member 208 and second side frame member 210 may be attached at lateral sides of top frame member 204 and bottom frame member 206. Accordingly, top frame member 204, bottom frame member 206, first side frame member 208, and second side frame member 210 may collectively define a compartment in which the plurality of storage bins 216 may be housed.
Storage bin assembly 200 may include a shaft 214 mounted to bin frame 202. Shaft 214 may be rotatable about axis of rotation A. As discussed previously, axis of rotation A may be orientated in the horizontal direction (i.e., in the lateral direction L when refrigerator door 128 is in a closed position). However, in some embodiments, axis of rotation A may be orientated in the vertical direction V. Shaft 214 may include a plurality of grooves 220 defined therein. Grooves 220 may be spaced apart circumferentially around shaft 214 in an equidistant manner. Any reasonable number of grooves 220 may be formed. In one example, eight grooves 220 are formed in shaft 214. Grooves 220 may be defined radially inward from an outer circumferential surface of shaft 214. Grooves 220 may extend an axial length of shaft 214. In detail grooves 220 may extend axially from a first end of shaft 214 to a second end of shaft 214 such that each groove 220 is exposed through the first end and the second end of shaft 214. In some embodiments, grooves 220 may extend to a predetermined distance through shaft 214, such that only one end of grooves 220 is exposed through the first end of shaft 214. In other words, grooves 220 may have a blind end defined axially down shaft 214. Grooves 220 may further define a restraint feature formed at a radially inward portion of groove 220. For example, each groove 220 may be defined in part by a retention flange 234 to form an undercut portion that extends circumferentially. In detail, each groove 220 may have a “T” shaped cross-section. However, grooves 220 may have any suitable cross-section, such as a wedge-shape cross-section, a circular cross-section, or the like.
Shaft 214 may be rotatably mounted within bin frame 202. For example, bin frame 202 may include one or more bearings (not shown) on which shaft may be mounted. In some embodiments, a first bearing is attached to first side frame member 208 and a second bearing is attached to second side frame member 210. Additionally or alternatively, the first bearing may be formed integrally (e.g., as one piece) with first side frame member 208 and the second bearing may be formed integrally (e.g., as one piece) with second side frame member 210. Additionally or alternatively, the first and second bearings may be attached to one or both of top frame member 204 and bottom frame member 206.
Storage bin assembly 200 may include a storage bin 216. In detail, storage bin assembly 200 may include a plurality of storage bins 216. Storage bin 216 may be removably attached to shaft 214. Storage bin 216 may include a plurality of pockets 236 defined therein. For example, pockets 236 may be spaced apart along the axis of rotation A of shaft 214 (i.e., axially). Any reasonable number of pockets 236 may be defined, for example three pockets 236, for example four pockets 236, for example six pockets 236, etc. Each of the pockets 236 may have an identical size. Additionally or alternatively, each pocket 236 may have a different size. Storage bin 216 may have a wedge-shaped cross-section. Accordingly, the plurality of storage bins 216 may be arranged circumferentially about shaft 214.
Storage bin 216 may include a protrusion 222 extending from a base 240 of storage bin 216. In detail, protrusion 222 may have a “T” shaped cross-section along the direction of the axis of rotation A (i.e., axially). Protrusion 222 may correspond to groove 220 in shaft 214. In other words, protrusion 222 may be complementary to groove 220. Accordingly, protrusion 222 may slide into groove 220 in the axial direction A so as to attach storage bin 216 to shaft 214.
Storage bin assembly 200 may include a bin door 218. Bin door 218 may be coupled to storage bin 216 to open and close the plurality of pockets 236. In detail, bin door 218 may be pivotally coupled to storage bin 216. In other words, bin door 218 may pivot about an axis parallel to the axis of rotation A of shaft 214. Accordingly, bin door 218 may rotate with respect to storage bin 216 to provide selective access to pockets 236. One or more bin doors 218 may be pivotally attached to each storage bin 216. For example, one individual bin door 218 may be provided for each individual pocket 236. In other words, a plurality of doors 218 may be attached to storage bin 216, and each door 218 may provide access to a single pocket 236. Additionally or alternatively, a single bin door 218 may provide selective access to all pockets 236 on storage bin 216. For another example, in
Storage bin assembly 200 may include a latching mechanism between bin door 218 and storage bin 216. For instance, latching mechanism may include a first magnet 228 and a second magnet 230. First magnet 228 may be positioned within and attached to a pocket 236 of storage bin 216. First magnet 228 may be positioned at a corner of pocket 236 opposite the axis of rotation of bin door 218. First magnet may be a push magnet configured to latch and release by pushing bin door 218 inward. Second magnet 230 may be attached to bin door 218. Second magnet 230 may be correspond to first magnet 228 such that first magnet 228 and second magnet 230 are magnetically coupled when bin door 218 is in a closed position (i.e., covering pockets 236).
Storage bin assembly 200 may include a driving mechanism. The driving mechanism may drive a rotation of shaft 214. The driving mechanism may include a motor 224. Motor 224 may be provided within bin frame 202. For instance, motor 224 may be attached to first side frame member 208. The location of motor 224 is not limited, however. Motor 224 may be a stepper motor. Additionally or alternatively, motor 224 may be a brushless direct current (DC) motor. The driving mechanism may include a driving gear 226 and a driven gear 242. Driving gear 226 may be rotated by motor 224 during an operation of motor 224. Driven gear 242 may be connected to shaft 214. For instance, driven gear 242 may be connected to shaft 214 via a pin connection. In some embodiments, driven gear 242 is integrally formed with shaft 214.
Driving gear 226 and driven gear 242 may be meshed such that a rotation of driving gear 226 in turn rotates driven gear 242. Accordingly, shaft 214 may rotate according to a rotation of motor 224. In the case where motor 224 is a stepper motor, motor 224 may rotate according to a predetermined schedule. In detail, a user may set motor 224 to rotate a predetermined amount on a regular schedule (e.g., daily, weekly, etc.). The predetermined amount to which motor rotates may correspond to a single storage bin 216. In other words, a user may set a schedule such that motor 224 rotates a predetermined arc length every twenty-four hours. The arc length may correspond to an arc length of storage bin 216. Thus, every twenty-four hours, a different storage bin 216 is accessible within bin frame 202. The driving mechanism may be a clock mechanism. In other words, driven gear 242 may be a Geneva gear.
Storage bin assembly 200 may further include a display screen 232. Display screen 232 may be attached to bin frame 202. For instance, display screen 232 may be attached to top frame member 204. Additionally or alternatively, display screen 232 may be attached to bin door 218. Display screen 232 may display information relating to the contents of storage bin 216 or a specific user to whom a particular storage bin 216 is associated. Display screen 232 may communicate with controller 134 and user interface panel 136. Thus, information displayed on display screen 232 may be customized by a user via user interface panel 136.
