Definitions
- the present subject matter relates generally to refrigerator appliances and ice making assemblies, and more particularly to features and methods for cleaning an ice making assembly (e.g., within a refrigerator appliance).
- Certain refrigerator appliances include an icemaker.
- liquid water is directed to the icemaker and frozen.
- a variety of ice types can be produced depending upon the particular icemaker used.
- certain icemakers include a mold body for receiving liquid water. An auger within the mold body can rotate and scrape ice off an inner surface of the mold body to form ice nuggets.
- Such icemakers are generally referred to as nugget style icemakers. Certain consumers prefer nugget style icemakers and their associated ice nuggets.
- Ice nuggets are generally stored at temperatures above the freezing temperature of liquid water to maintain a texture of the ice nuggets. When stored at such temperatures, at least a portion of the ice nuggets will melt to liquid water. Generally, liquid water can thus accumulate within an ice bucket of the ice making assembly. This may create a number of difficulties or undesirable conditions for the refrigerator appliance. For instance, some of liquid water every freeze, causing portions of the nugget ice to clump together such that dispensing ice nuggets is difficult. Moreover, liquid water may damage or negatively affect performance of electrical components, such as motors. Furthermore, the liquid water may be difficult to remove and, in some instances, drip or flow from an ice dispensing portion of the refrigerator appliance.
- a refrigerator appliance or ice making assembly addressing one or more of the above identified issues.
- US20190257565A1 relates to an ice maker with a main water reservoir and a sanitizer reservoir for automatically descaling and sanitizing the ice maker.
- the main water reservoir is filled with water to an ice making water level, a descale water level, and a sanitize water level.
- the sanitizer reservoir is filled with a sanitizer and is in fluid communication with the main water reservoir.
- the ice maker also includes a water distributor and a water pump for supplying water to the sump.
- US20120118001A1 relates to an ice-making assembly for a refrigeration appliance which includes an ice maker for making ice cubes.
- An ice cube storage bin receives ice cubes from the ice maker.
- the ice cube storage bin is maintained at a temperature above the freezing temperature of water.
- a drain in communication with the ice cube storage bin receives water melted from ice cubes located in the storage bin.

- FIG. 1 illustrates a perspective view of a refrigerator 100.
- Refrigerator appliance 100 includes a cabinet or housing 102 that extends between a top 104 and a bottom 106 along a vertical direction V, between a first side 108 and a second side 110 along a lateral direction L, and between a front side 112 and a rear side 114 along a transverse direction T.
- Each of the vertical direction V, lateral direction L, and transverse direction T are mutually perpendicular to one another.
- Housing 102 defines chilled chambers for receipt of food items for storage.
- housing 102 defines fresh food chamber 122 positioned at or adjacent top 104 of housing 102 and a freezer chamber 124 arranged at or adjacent bottom 106 of housing 102.
- 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 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 128 are rotatably hinged to an edge of housing 102 for selectively accessing fresh food chamber 122.
- 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 position in FIG. 1 .
- Refrigerator appliance 100 also includes a delivery assembly 140 for delivering or dispensing liquid water or ice.
- Delivery assembly 140 includes a dispenser 142 positioned on or mounted to an exterior portion of refrigerator appliance 100 (e.g., on one of refrigerator doors 128).
- 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.
- any suitable actuating mechanism may be used to operate dispenser 142.
- dispenser 142 can include a sensor (such as an ultrasonic sensor) or a button rather than the paddle.
- a control panel 148 is provided for controlling the mode of operation.
- control 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 refrigerator doors 128.
- dispenser recess 150 is positioned at a level that approximates the chest level of a user.
- the dispensing assembly 140 may receive ice from an icemaker disposed in a sub-compartment of the fresh food chamber 122.
- FIG. 2 provides a perspective view of a door of refrigerator doors 128.
- optional embodiments of refrigerator appliance 100 includes a sub-compartment 160 defined on refrigerator door 128.
- Sub-compartment 160 is often referred to as an "icebox.”
- sub-compartment 160 extends into fresh food chamber 122 when refrigerator door 128 is in the closed position.
- FIG. 3 provides a schematic view of certain components of refrigerator appliance 100.
- refrigerator appliance 100 includes a sealed cooling system 180 for executing a vapor compression cycle for cooling air within refrigerator appliance 100 (e.g., within fresh food chamber 122 and freezer chamber 124).
- Sealed cooling system 180 includes a compressor 182, a condenser 184, an expansion device 186, and an evaporator 188 connected in fluid series and charged with a refrigerant.
- sealed cooling system 180 may include additional components (e.g., at least one additional evaporator, compressor, expansion device, or condenser).
- sealed cooling system 180 may include two evaporators.
- gaseous refrigerant flows into compressor 182, which operates to increase the pressure of the refrigerant.
- This compression of the refrigerant raises its temperature, which is lowered by passing the gaseous refrigerant through condenser 184.
- condenser 184 heat exchange with ambient air takes place so as to cool the refrigerant and cause the refrigerant to condense to a liquid state.
- Expansion device 186 receives liquid refrigerant from condenser 184. From expansion device 186, the liquid refrigerant enters evaporator 188. Upon exiting expansion device 186 and entering evaporator 188, the liquid refrigerant drops in pressure and vaporizes. Due to the pressure drop and phase change of the refrigerant, evaporator 188 is cool relative to fresh food and freezer chambers 122 and 124 of refrigerator appliance 100. As such, cooled air is produced and refrigerates fresh food and freezer chambers 122 and 124 of refrigerator appliance 100. Thus, evaporator 188 is a heat exchanger which transfers heat from air passing over evaporator 188 to refrigerant flowing through evaporator 188.
- evaporator 188 is a heat exchanger which transfers heat from air passing over evaporator 188 to refrigerant flowing through evaporator 188.
- refrigerator appliance 100 further includes a valve 194 (e.g., in fluid communication with a water supply line 272) for regulating a flow of liquid water to a fluid flow path 260 or an icemaker 210 therealong.
- Valve 194 is selectively adjustable between an open configuration and a closed configuration. In the open configuration, valve 194 permits a flow of liquid water to icemaker 210. Conversely, in the closed configuration, valve 194 hinders the flow of liquid water to icemaker 210.
- refrigerator appliance 100 also includes an air handler 192.
- Air handler 192 may be operable to urge a flow of chilled air from an evaporator ( FIG. 3 ) (e.g., within a freezer chamber 124) into icebox compartment 160 (e.g., via supply and return ducts or chilled air passages) and may be any suitable device for moving air.
- air handler 192 can be an axial fan or a centrifugal fan.
- Operation of the refrigerator appliance 100 can be regulated by a controller 190 that is operably coupled to (e.g., in electrical or wireless communication with) user interface panel 148, sealed cooling system 180, or various other components.
- User interface panel 148 provides selections for user manipulation of the operation of refrigerator appliance 100, such as dispensing ice, chilled water, or other various options.
- controller 190 may operate various components of the refrigerator appliance 100.
- Controller 190 may include a memory and one or more 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 100.
- the memory may represent random access memory such as DRAM, or read only memory such as ROM or FLASH.
- 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.
- 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.
- Controller 190 may be positioned in a variety of locations throughout refrigerator appliance 100. In the illustrated embodiment, controller 190 is located within the user interface panel 148. In other embodiments, controller 190 may be positioned at any suitable location within refrigerator appliance 100, such as for example within a fresh food chamber, a freezer door, etc. Input/output ("I/O") signals may be routed between controller 190 and various operational components of refrigerator appliance 100. For example, user interface panel 148 may be in communication with controller 190 via one or more signal lines or shared communication busses.
- controller 190 may be in communication with the various components of refrigerator appliance 100 and may control operation of the various components.
- the various valves, switches, etc. may be actuatable based on commands from controller 190.
- interface panel 148 may additionally be in communication with controller 190.
- the various operations may occur based on user input or automatically through controller 190 instruction.

- icemaker 210 may be an air cooled icemaker 210.
- Chilled air from the sealed system 180 may also cool ice storage bin 212.
- air around ice storage bin 212 can be chilled to a temperature above the freezing temperature of liquid water (e.g., to about the temperature of fresh food chamber 122, such that ice nuggets in ice storage bin 212 melt over time due to being exposed to air having a temperature above the freezing temperature of liquid water).

- FIG. 10 depicts steps performed in a particular order for purpose of illustration and discussion.
- the method 400 includes providing a cleaning cartridge containing a cleaning agent along a fluid flow path between an icemaker, such as a nugget icemaker, and a fluid storage volume (e.g., first storage volume or second storage volume, as discussed above).
- the cleaning cartridge is provided in a cartridge mounting region.
- the cleaning cartridge may be provided as a replacement for a recirculation filter (e.g., provided as a kit).
- 410 may include replacing the recirculation filter within the cartridge mounting region.
- the replaced recirculation filter may be maintained apart from the cabinet or remainder of the appliance (e.g., for the duration of method 400).
- Such a replacement may be performed by a user (e.g., manually) and may include any steps required to typically replace a recirculation filter (e.g., following the expiration of the recirculation filter's usable lifespan).
- Step 440 includes directing water through the catch cup positioned below the icemaker.
- the catch cup may be pivotably mounted to move between a storage position and a cleaning position.
- 440 may include providing the catch cup in the cleaning position such that water is funneled from the icemaker to an outlet (e.g., apex outlet) of the catch cup.
- the method 400 includes motivating the cleaning solution to the icemaker through the fluid storage volume.
- the cleaning solution is collected (e.g., as motivated, at least in part, by gravity) in the first storage volume defined by the storage tank positioned below the cleaning cartridge.
- the cleaning solution may be pumped (e.g., by the fluid pump) to the second storage volume defined by the upper reservoir.
- the fluid pump may pump the cleaning solution along the fluid path from the first storage volume and upward to the second storage volume.
- the method 400 includes opening a drain line downstream from the cleaning cartridge between the fluid storage volume and the icemaker to guide the cleaning solution from the fluid flow path.
- the second drain line may be opened downstream from the second storage volume, as described above.
- the first drain line may be opened downstream from the cleaning cartridge or first storage volume, as also described above.
- 460 may be initiated by a determined expiration of the cleaning operation.
- the cleaning operation may have a predetermined time period (e.g., in seconds or minutes) in which the fluid (e.g., water or the cleaning solution) is to be motivated through the ice making assembly.
- the fluid e.g., water or the cleaning solution
- 460 may be initiated.
- 460 may be initiated at a user-selected moment, such as in response to a user input to drain the cleaning solution.
