FLUIDIZER FOR AN ICE DISPENSING ASSEMBLY OF A COOLING COMPARTMENT
A fluidizer for an ice dispensing assembly of a cooling compartment. The fluidizer has at least one base member. At least one angular projection may be coupled with or integrally formed with a surface of the base member. Rotation of fluidizer fluidizes ice cubes located in the ice bucket. The ice cubes are fluidized when the at least one angular projection contacts the ice cubes and forces the ice cubes away from the at least one base member. The rotational kinetic enemy imparted by the fluidizer breaks up any fused ice cubes so that the influence of gravity can pull ice downwards for dispensing.
1. Field of the Invention
The field of the invention relates generally to a cooling compartment, and more particularly, to an ice dispensing assembly of a cooling appliance.
2. Related Art
Generally, a cooling appliance includes a fresh food compartment and a freezer compartment which are partitioned from each other to store various foods at low temperatures in appropriate states for relatively long time.
An ice making system is typically mounted within the freezer compartment. The ice making system makes ice and stores ice in an ice bucket until ice cubes are requested by a user. The ice cubes are then generally dispensed at an ice dispenser located on an outside door of the freezer compartment.
However, the ice cubes stored in the ice bucket are usually in a stagnant position, which can prevent ice delivery through the ice dispenser. For example, the ice cubes in the ice bucket may have formed large clumps of ice since the previous instance of ice dispensing. This creates a problem in conventional ice dispensers because stagnant and clumped ice cubes cannot readily move through the ice dispensing system for delivery to a user. As a result, the effectiveness of conventional ice dispensers can be compromised.
BRIEF SUMMARY OF THE INVENTIONAs described herein, the exemplary embodiments of the present invention overcome one or more of the above or other disadvantages known in the art.
An aspect of the present invention relates to a fluidizer. The fluidizer has at least one base member and an angular projection on the at least one base member. Another aspect of the present invention relates to an ice dispensing assembly having a fluidizer. Yet another aspect of the present invention relates to a cooling compartment having a fluidizer.
The fluidizer fluidizes the ice cubes within the ice bucket when the fluidizer is rotating. Rotation of fluidizer fluidizes the ice cubes located in the ice bucket by pushing the ice cubes, in contact with the at least one angular projection of fluidizer, upwards. Kinetic energy provided by the rotation of the fluidizer breaks up any fused ice cubes so that the influence of gravity can pull ice downwards in order to be dispensed. As such, motion is imparted to stagnant ice cubes stored in the ice bucket creating a more effective ice dispensing system.
These and other aspects and advantages of the present invention will become apparent from the following detailed description considered in conjunction with the accompanying drawings. It is to be understood, however, that the drawings are designed solely for purposes of illustration and not as a definition of the limits of the invention, for which reference should be made to the appended claims. Moreover, the drawings are not necessarily drawn to scale and that, unless otherwise indicated, they are merely intended to conceptually illustrate the structures described herein.
Reference is now made briefly to the accompanying drawings, in which:
In one embodiment, the freezer compartment 104 and the fresh food compartment 102 are arranged in a side-by-side configuration in the body 106 of the cooling appliance 100. Although the cooling appliance 100 in
Referring again to
The freezer compartment 104 contains an automatic ice maker 250 positioned proximate and above an ice bucket 260 disposed in and/or on the inside wall of access door 134. Although the ice maker 250 is shown in
The ice dispensing assembly 300 comprises ice bucket 260, a fluidizer 310, and motor 322. Ice dispensing assembly 300 may also comprise rotatable blades 320 and/or ice chute 330. Ice bucket 260 is mounted on access door 134 such that a rear wall 301 of ice bucket 260 comes into contact with an inner wall of access door 134 inside freezer compartment 104. Alternatively, a portion of the inner wall of access door 134 can serve as the rear wall 301 of ice bucket 260.
The fluidizer 310 is positioned within or below the ice bucket 260 and serves as a portion of the bottom surface of ice bucket 260. The fluidizer 310 comprises at least one base member 375. At least one angular projection 311 is mounted on, attached to, coupled with, and/or integrally formed with the base member 375 of the fluidizer 310. The shape of the base member 375, as viewed from the top down, varies depending on the embodiment. For example, the base member 375 may vary in width along its length outwardly from a center of the fluidizer 310. In one embodiment, base member 375 widens in width outwardly from a center of the fluidizer 310. In another embodiment, the base member 375 narrows in width outwardly from a center of the fluidizer 310. In yet another embodiment, the width of the base member 375 remains constant along its length.
In one embodiment, the fluidizer 310 comprises an even number of opposing base members 375. The even number of opposing base member 375 may be, but are not required to be, identical. For example, the even number of opposing base member 375 may or may not have the same shape, width, and/or length. For example,
In another embodiment the fluidizer 310 comprises an odd number of base members that may or may not have the same shape, width and/or length. For example,
Referring again to
In an embodiment, the motor 322 is coupled with the fluidizer 310. In one embodiment, this coupling occurs via a shaft 328. All or a portion of the shaft 328 may be positioned within the interior of the ice dispensing assembly 300. In an embodiment, at least a portion of the shaft 328 is coupled with or positioned adjacent the ice bucket 260. Rotatable blades 320 may also be coupled to motor 322 through their assembly to shaft 328. Shaft 328 extends through rigid stops 344 and 345 for coupling to a drive shaft 323, which is in turn coupled to motor 322. The coupling between shaft 328 and drive shaft 323 may be accomplished through coupling mechanism 324. Although shaft 328 is illustrated in
Stop 344 is positioned below fluidizer 310 and above rotatable blades 320 and is configured for use as a blade cover. As illustrated in
Turning back to
In one embodiment, the rotation of fluidizer 310 causes the at least one angular projection 311 located on fluidizer 310 to also rotate. Since fluidizer 310 may serve as a portion of the bottom surface of ice bucket 260, as discussed above, a plurality of the ice cubes 315 in bucket 260 are in contact with fluidizer 310. Therefore, as fluidizer 310 rotates, the ice cubes 315 that are in contact with the at least one angular projection 311 of fluidizer 310 are pushed upward. In other words, during rotation of fluidizer 310, the at least one angular projection 311 imparts upward rotational kinetic energy to ice cubes 315. The shape of the at least one angular projection 311 in combination with the rotation of the at least one angular projection 311 pushes upward the ice cubes 315 that are in contact with the at least one angular projection 311. In other words, a portion of the rotational kinetic energy introduced to the ice cubes 315 in contact with the at least one angular projection 311 is transferred upward because of the angular shape of the at least one angular projection 311. As a result, the bottom ice cubes 315 in contact with the at least one angular projection 311 push upward on ice cubes 315 above them. The upward and rotational vectors of kinetic energy transferred to the ice cubes 315 via the at least one angular projection 311 fluidizes the ice cubes 315 located in ice bucket 260, which allows gravity to pull ice cubes 315 downward. The force of gravity, which causes the eventual downward motion of the fluidized ice cubes 315, pulls ice cubes 315 through opening 333 of stop 344 in order to eventually reach ice chute 330.
During operation, the rotational direction of fluidizer 310 (and rotatable blades 320) indicates the region of rotatable blades 320 through which ice cubes 315 descend. For example, if fluidizer 310 and rotatable blades 320 are rotated in a first direction (for example, counterclockwise), ice cubes 315 fall through opening 333, as described above, and are then driven by rotatable blades 320 into stationary crusher blades 326. Rotatable blades 320 rotate past stationary crusher blades 326. The driving force of rotatable blades 320 traps ice cubes 315 against stationary crusher blades 326 and ultimately crushes ice cubes 315. After being sufficiently crushed, ice cubes 315 can pass from the region of stationary crusher blades 326 to exit 335. Alternatively, for example, if fluidizer 310 and rotatable blades 320 are rotated in a second direction (for example, clockwise), ice cubes 315 are swept directly from opening 333 to the exit 335 and no crushing occurs.
Once at exit 335, ice cubes 315 fall through ice chute 330 to ice dispenser 115, which dispenses the ice cubes 315 through access door 134. Although
In an embodiment, the pair of ramps 411, 412 and 413, 414 on each side of fluidizer 410 meet along their top edges 420 to define the top edge of the at least one angular projection 311. The pair of ramps 411, 412 and the pair of ramps 413, 414 may be, but are not required to be, identical. For example, the pair of ramps 411, 412 and the pair of ramps 413, 414 may or may not have the same shape, width, and/or length. In an embodiment, ramps 411, 412, 413, and 414 are identical in shape, length and width. However, ramps 411, 412, 413, and 414 need not be identical as long as the pair of ramps 411, 412 and 413, 414, which form each side of bow-tie fluidizer 410, meet along their top edges 420 to define angular projection 311. Ramps 411, 412, 413, and 414 may have, but are not limited to, a slope of about 45°.
Referring to
In an alternative embodiment of fluidizer 510, the distance between the top edge 520 of angular projection 311 and an edge of base member 575 varies in length outwardly from a center of the fluidizer 510. For example, the distance between the top edge 520 of angular projection 311 and edge 525 of base member 575 increases in length as the distance from shaft 328 increases. In an alternative embodiment, the distance between top edge 520 of angular projection 311 and an edge of base member 575 decreases in length as the distance from shaft 328 increases. In yet another alternative embodiment, the distance between the top edge 520 of angular projection 311 and an edge of base member 575 remains constant as the distance from shaft 328 increases. Ramps 511, 512, 513, and 514 may have, but are not limited to, a slope of about 45°. As such, the interior top angles y and z of lateral faces 515 and 516, respectively, may be, but are not limited to about 90°.
In one embodiment, fluidizer 310, 410, 510, 610 is a solid substrate, but in other embodiments, the substrate that forms the fluidizer 310, 410, 510, 610 may be hollow. Non-limiting examples of such a substrate include but are not limited to plastic and/or metal. Although
