The present subject matter relates generally to assemblies for storing and dispensing ice, and more particularly to ice bin assemblies for use in refrigerator appliances.
Certain refrigerator appliances include an ice maker. In order to produce ice, liquid water is directed to the ice maker and frozen. A variety of ice types can be produced depending upon the particular ice maker used. For example, certain ice makers include a mold body for receiving liquid water. An auger or ejector within the mold body can rotate and scrape ice off an internal surface of the mold body to form ice nuggets or cubes. Once ice is scraped off the mold body, it may be stored within an ice bin or bucket within refrigerator appliance. In order to maintain ice in a frozen state, the ice bin is positioned within a chilled chamber of the refrigerator appliance or a separate compartment behind one of the doors. In some appliances, a dispenser is provided in communication with the ice bin to automatically dispense a selected or desired amount of ice to a user (e.g., through a door of the user appliance). Typically, a rotating agitator or sweep is a provided within the ice bin to help move ice from the ice bin to the dispenser.
Although delivery of ice through, for example, a door of a refrigerator appliance may be useful, existing systems present a number of problems. As an example, it may be difficult to see ice within the ice bin. As another example, there may be instances when a user may wish to remove an ice bin from the refrigerator appliance. However, removal of an ice bin can be difficult and cumbersome in many existing appliances. If an agitator or sweep is provided, it may be difficult to remove or manage the rotating agitator or sweep within an ice bin. Ice may periodically melt and refreeze within the ice bin, making it especially difficult to remove or rotate the sweep or agitator. In some existing appliances, a top opening of the ice bin (e.g., through which ice falls into the ice bin from the ice maker) must be kept relatively small so that the sweep or agitator can be supported at a top portion of the ice bin. A motor may be provided to drive the sweep or agitator. However, it may be difficult to arrange the motor and agitator connection in such a way that does not further restrict access to the ice bin or a user's ability to remove the ice bin from the refrigerator appliance.
As a result, there is a need for an improved refrigerator appliance and ice bin assembly. In particular, it would be advantageous to provide a refrigerator or ice bin addressing one or more of the above identified issues.
Aspects and advantages of the invention will be set forth in part in the following description, or may be obvious from the description, or may be learned through practice of the invention.
In one exemplary aspect of the present disclosure, an ice bin of an ice making assembly is provided. The ice bin may include a bin body, an ice sweep, a sweep gear, and a drive gear. The bin body may define a storage volume to receive ice therein. The ice sweep may be positioned below the storage volume. The sweep gear may be rotatable about a sweep axis. The drive gear may be positioned in mechanical communication with the sweep gear. The drive gear may be rotatable about a drive axis, the drive axis extending along a non-parallel angle relative to the sweep axis.
In another exemplary aspect of the present disclosure, a refrigerator appliance is provided. The refrigerator appliance may include a cabinet, a door, a bin motor, and an ice bin. The cabinet may define a chilled chamber. The door may be door rotatable between an open position permitting access to the chilled chamber and a closed position restricting access to the chilled chamber. The bin motor may be attached to the cabinet. The ice bin may be removably received within the chilled chamber and in selective mechanical communication with the bin motor. The ice bin may include a bin body, an ice sweep, a sweep gear, and a drive gear. The bin body may define a storage volume to receive ice therein. The ice sweep may be positioned below the storage volume. The sweep gear may be rotatable about a sweep axis. The drive gear may be positioned in mechanical communication with the sweep gear. The drive gear may be rotatable about a drive axis, the drive axis extending along a non-parallel angle relative to the sweep axis.
These and other features, aspects and advantages of the present invention will become better understood with reference to the following description and appended claims. The accompanying drawings, which are incorporated in and constitute a part of this specification, illustrate embodiments of the invention and, together with the description, serve to explain the principles of the invention.
A full and enabling disclosure of the present invention, including the best mode thereof, directed to one of ordinary skill in the art, is set forth in the specification, which makes reference to the appended figures.
Reference now will be made in detail to embodiments of the invention, one or more examples of which are illustrated in the drawings. Each example is provided by way of explanation of the invention, not limitation of the invention. In fact, it will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the scope or spirit of the invention. For instance, features illustrated or described as part of one embodiment can be used with another embodiment to yield a still further embodiment. Thus, it is intended that the present invention covers such modifications and variations as come within the scope of the appended claims and their equivalents.
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”). 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.
Turning now to the figures,
As shown, refrigerator appliance 100 includes a cabinet or housing 120 that extends between a top 101 and a bottom 102 along a vertical direction V. Housing 120 defines chilled chambers for receipt of food items for storage. In particular, housing 120 defines fresh food chamber 122 positioned at or adjacent top 101 of housing 120 and a freezer chamber 124 arranged at or adjacent bottom 102 of housing 120. As such, refrigerator appliance 100 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, a side-by-side style refrigerator appliance or a standalone ice-maker 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 128 are rotatably hinged to an edge of housing 120 for selectively accessing fresh food chamber 122. In addition, a freezer door 130 is arranged below refrigerator doors 128 for selectively accessing freezer chamber 124. Freezer door 130 is coupled to a freezer drawer (not shown) slidably mounted within freezer chamber 124. Refrigerator doors 128 and freezer door 130 are shown in the closed configuration in
Refrigerator appliance 100 also includes a dispensing assembly 140 for dispensing liquid water or ice. Dispensing assembly 140 includes a dispenser 142 positioned on or mounted to an exterior portion of refrigerator appliance 100 (e.g., on one of doors 120). Dispenser 142 includes a discharging outlet 144 for accessing ice and liquid water. An actuating mechanism 146, shown as a paddle, is mounted below discharging outlet 144 for operating dispenser 142. In alternative exemplary embodiments, any suitable actuating mechanism may be used to operate dispenser 142. For example, dispenser 142 can include a sensor (such as an ultrasonic sensor) or a button rather than the paddle. A user interface panel 148 is provided for controlling the mode of operation. For example, user interface panel 148 includes a plurality of user inputs (not labeled), 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 144 and actuating mechanism 146 are an external part of dispenser 142 and are mounted in a dispenser recess 150. Dispenser recess 150 is positioned 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 120. In the exemplary embodiment, dispenser recess 150 is positioned at a level that approximates the chest level of a user.
In some embodiments, refrigerator appliance 100 includes a sub-compartment 162 defined on refrigerator door 128. Sub-compartment 162 is often referred to as an “icebox.” Sub-compartment 162 extends into fresh food chamber 122 when refrigerator door 128 is in the closed position. As discussed in greater detail below, an ice maker or ice making assembly 160 and an ice storage bin 164 (
In optional embodiments, an access door 166 is hinged to refrigerator door 128. Access door 166 permits selective access to sub-compartment 162. Any manner of suitable latch 168 is configured with sub-compartment 162 to maintain access door 166 in a closed position. As an example, latch 168 may be actuated by a consumer in order to open access door 166 for providing access into sub-compartment 162. Access door 166 can also assist with insulating sub-compartment 162 (e.g., by thermally isolating or insulating sub-compartment 162 from fresh food chamber 122). It is noted that although an access door 166 is illustrated in exemplary embodiments, alternative embodiments may be free of any separate access door. For instance, ice storage bin 164 may be immediately visible upon opening door 128.
In certain embodiments, ice making assembly 160 is positioned or disposed within sub-compartment 162. As illustrated, ice making assembly 160 may include a mold body or casing 170. In some such embodiments, auger 172 is rotatably mounted in a mold body within casing 170 (shown partially cutout to reveal auger 172). In particular, a motor 174 is mounted to casing 170 and is in mechanical communication with (e.g., coupled to) auger 172. Motor 174 is configured for selectively rotating auger 172 in the mold body within casing 170. During rotation of auger 172 within the mold body, auger 172 scrapes or removes ice off an inner surface of the mold body within casing 170 and directs such ice to an extruder 175. At extruder 175, ice nuggets are formed from ice within casing 170. An ice bucket or storage bin assembly 164 is positioned below extruder 175 and receives the ice nuggets from extruder 175. From storage bin assembly 164, the ice nuggets can enter dispensing assembly 140 and be accessed by a user as discussed above. In such a manner, ice making assembly 160 can produce or generate ice nuggets.
Ice making assembly 160 also includes a fan 176. Fan 176 is configured for directing a flow of chilled air towards casing 170. As an example, fan 176 can direct chilled air from an evaporator of a sealed system through a duct to casing 170. Thus, casing 170 can be cooled with chilled air from fan 176 such that ice making assembly 160 is air cooled in order to form ice therein. Ice making assembly 160 also includes a heater 180, such as an electric resistance heating element, mounted to casing 170. Heater 180 is configured for selectively heating casing 170 (e.g., when ice prevents or hinders rotation of auger 172 within casing 170).
It is noted that although ice making assembly 160 is illustrated as a nugget ice maker, the present disclosure is not limited to any particular style or configuration for making ice. As is understood by one of ordinary skill, other exemplary embodiments may include an ice making assembly configured to make ice flakes, solid pieces of ice (e.g., cubes or crescents), or any other suitable form of frozen ice.
Operation of refrigerator appliance 100 is generally controlled by a processing device or controller 190. Controller 190 may, for example, be operatively coupled to control panel 148 for user manipulation to select features and operations of refrigerator appliance 100, such as ice bin 164 or ice making assembly 160. Controller 190 can operate various components of refrigerator appliance 100 to execute selected system cycles and features. In exemplary embodiments, controller 190 is in operative communication (e.g., electrical or wireless communication) with ice bin 164. In additional or alternative embodiments, controller 190 is in operative communication with ice making assembly 160 (e.g., at motor 174, fan 176, and heater 180). Thus, controller 190 can selectively activate and operate ice bin 164, motor 174, fan 176, or heater 180.
Controller 190 may include a memory and microprocessor, such as a general or special purpose microprocessor operable to execute programming instructions or micro-control code associated with operation of ice making assembly 160. The memory may represent random access memory such as DRAM, or read only memory such as ROM or FLASH. In one embodiment, the processor executes programming instructions stored in memory. The memory may be a separate component from the processor or may be included onboard within the processor. Alternatively, controller 190 may be constructed without using a microprocessor (e.g., 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. One or more portions of storage bin assembly 164, bin motor 202, or ice making assembly 160 may be in communication with controller 190 via one or more signal lines or shared communication busses.
In optional embodiments, ice making assembly 160 also includes a temperature sensor 178. Temperature sensor 178 is configured for measuring a temperature of casing 170 or liquids, such as liquid water, within casing 170. Temperature sensor 178 can be any suitable device for measuring the temperature of casing 170 or liquids therein. For example, temperature sensor 178 may be a thermistor or a thermocouple. Controller 190 can receive a signal, such as a voltage or a current, from temperature sensor 190 that corresponds to the temperature of the temperature of casing 170 or liquids therein. In such a manner, the temperature of casing 170 or liquids therein can be monitored or recorded with controller 190.

As shown, a gear assembly 230 is provided within bin body 210 below storage volume 222. An ice sweep 232 positioned within bin body 210 may be in mechanical communication with gear assembly 230 to rotate about a predetermined axis (e.g., a sweep axis X or parallel to the vertical direction V). In some such embodiments, ice sweep 232 is positioned below storage volume 222. In additional or alternative embodiments, ice sweep 232 is positioned above dispenser opening 226. During use, ice sweep 232 may thus rotate (e.g., as directed by gear assembly 230) and motivate or direct ice within storage volume 222 to dispenser opening 226. Advantageously, the gear assembly 230 may establish a low center of gravity for bin assembly 200 and prevent accidental tipping of bin assembly 200 (e.g., when removed from refrigerator appliance 100 and placed on a counter). Further advantageously, the illustrated gear assembly 230 may permit a user to easily mount or remove bin assembly 200.
In certain embodiments, an ice cover 234 is positioned between ice sweep 232 and storage volume 222 along the vertical direction V may at least partially cover ice sweep 232 and provide support to ice within storage volume 222. Ice cover 234 may thus at least partially define a bottom extreme of storage volume 222. In some such embodiments, ice cover 234 defines a cover opening 236 that generally extends along the vertical direction V between storage volume 222 and ice sweep 232. In certain embodiments, cover opening 236 is vertically offset (e.g., circumferentially spaced apart from) dispenser opening 226. In other words, cover opening 236 may be misaligned from dispenser opening 226 along the vertical direction V. An internal guide wall 228 within bin body 210 below ice sweep 232 may define a channel 238 in fluid communication between cover opening 236 and dispenser opening 226. Optionally, internal guide wall 228 may have a frustoconical shape defined about sweep axis X. A vertical containment wall 240 may extend from, and about, a portion of internal guide wall 228. A radial internal opening 242 may be defined by internal guide wall 228 and vertical containment wall 240. As shown, radial opening 242 may be positioned above, and in upstream fluid communication with, dispenser opening 226.
During use, ice may pass from cover opening 236 to dispenser opening 226 through the channel 238 defined by an internal guide wall 228. As ice sweep 232 rotates, ice within storage volume 222 may thus pass through cover opening 236 to ice sweep 232 (e.g., as motivated by gravity). Ice sweep 232 may then motivate or direct such ice along internal guide wall 228, through a radial internal opening 242, and to dispenser opening 226.
As shown, the gear assembly 230 generally includes one or more rotatable gears in mechanical communication with ice sweep 232. In particular, a sweep gear 244 may be connected to ice sweep 232 below storage volume 222. For instance, sweep gear 244 may be fixed to ice sweep 232 (e.g., through a vertical shaft 246 extending from ice sweep 232) and rotatable about a sweep axis X. In some such embodiments, rotation of sweep gear 244 may be directly transferred to ice sweep 232. One or more stabilizing bearings 248, 250 may be fixed within bin body 210 (e.g., in horizontal or radial support of sweep gear 244). For instance, a bottom stabilizing bearing 248 may be radially positioned between sweep gear 244 and a base wall 221 of bin body 210. Moreover, bottom stabilizing bearing 248 may be vertically positioned below sweep gear 244. Additionally or alternatively, a top stabilizing bearing 250 may be radially positioned between vertical shaft 246 and the internal guide wall 228. Moreover, top stabilizing bearing 250 may be positioned above sweep gear 244. As shown, top stabilizing bearing 250 may be also positioned below ice sweep 232 or internal storage volume 222. Advantageously, the stabilizing bearings the may ensure sweep gear 244 maintains vertical alignment along the sweep axis X during use.
In some embodiments, an ice agitator 252 is positioned within storage volume 222. For instance, ice agitator 252 may extend vertically through or from ice cover 234 to a location within storage volume 222 (e.g., below bin opening 224). In some such embodiments, ice agitator 252 includes, or is provided as, a single, continuous, folded wire. The wire of ice agitator 252 may extend as an integral (e.g., unitary and monolithic) structure from a fixed end 254 (e.g., connecting the gear assembly 230) to a free end 256 uncovered and unsupported within storage volume 222. In certain embodiments, ice agitator 252 is fixed to ice sweep 232. Both ice agitator 252 and ice sweep 232 may thus rotate in tandem about sweep axis X. Optionally, one or more sealing structures (e.g., mated gasket-channel about sweep axis X) may be formed on ice sweep 232 or ice agitator 252 to prevent water from flowing to gear assembly 230. As an example, one gasket may be positioned on ice sweep 232 between vertical shaft 248 and internal guide wall 229. As another example, a separate gasket may be positioned on ice agitator 252 between ice agitator 252 and cover 234 or top bearing 250.
Within bin body 210, a drive gear 245 may be positioned in mechanical communication with sweep gear 244 (e.g., such that sweep gear 244 is in mechanical communication between ice sweep 232 and drive gear 245). For instance, drive gear 245 and sweep gear 244 may both include a plurality of gear teeth that are enmeshed in mechanical communication with each other. When assembled, drive gear 245 may be rotatable about a unique drive axis E that is not parallel to sweep axis X. For instance, drive axis E may be perpendicular to sweep axis X. Moreover, one or both of sweep gear 244 and drive gear 245 may be provided as bevel gears.
In certain embodiments, an adapter key 258 is connected to drive gear 245 through bin body 210. For instance, a gear shaft 260 may extend through bin body 210 from drive gear 245 to adapter key 258. In some such embodiments, gear shaft 260 and adapter key 258 are both fixed to drive gear 245 and rotatable about drive axis E. When storage bin assembly 200 is positioned on refrigerator appliance (e.g., attached to a door 128—

In optional embodiments, storage bin assembly 200 includes a selective sealing system 272 to selectively permit or restrict water from exiting reservoir body 262. In exemplary embodiments, a resilient or biased sealing plug 274 is paired to drain aperture 270. For instance, biased sealing plug 274 may be slidable along the vertical direction V within drain aperture 270. Generally, sealing system 272 selectively fills or blocks drain aperture 270 according to a condition of storage bin assembly 200. For instance, in a fully mounted condition (e.g., wherein storage bin assembly 200 is fully attached to and supported on refrigerator appliance 100—
A spring 276 may be attached to biased sealing plug 274 in biased engagement. Spring 276 may generally urge biased sealing plug 274 toward drain aperture 270. For instance, spring 276 may be embodied as a compression spring. Spring 276 may be positioned between a support tab 278 and biased sealing plug 274. In some such embodiments, support tab 278 is fixed within reservoir body 262.
A plug prong 280 may be provided in some embodiments of sealing system 272. For instance, plug prong 280 may be attached to cabinet 102 (
