Abstract: An icemaker includes a casing that receives water from a water supply and is in thermal communication with an evaporator of a sealed system that chills the casing to freeze the water. An auger is mounted within the interior volume and is rotatable to scrape the ice from the casing and urge it through an extruder to form nugget ice. A BLDC motor is mechanically coupled to the auger to selectively rotate the auger. A controller determines a target speed of the auger based at least in part on the ice production parameter, and operates the BLDC motor to rotate the auger at the target speed. The BLDC motor with the speed-closed control loop can provide the constant speed and enough torque to prevent the ice maker from freezing. The controller can adjust the PWM and the voltage will be adjusted slightly, then the torque will be adjusted accordingly.

Abstract: An ice making assembly includes a mold body defining an ice-making cavity. An evaporator is coupled to the mold body. The evaporator includes a cap positioned on the mold body such that an open end of the cap is positioned at the mold body. An inlet tube is mounted to the cap. An outlet tube is also mounted to the cap. An evaporation chamber is formed between the cap and the mold body. The inlet tube is configured for directing a flow of refrigerant into the evaporation chamber, and the outlet tube configured for directing the flow of refrigerant out of the evaporation chamber.

Abstract: A stand-alone ice making appliance, includes a casing. A water tank, an ice maker, and a pump are disposed within the casing. The pump is operable to circulate water from the water tank to the ice maker. An auxiliary water reservoir is disposed outside of the casing. The auxiliary water reservoir is in fluid communication with the water tank such that water within the auxiliary water reservoir is flowable to the water tank. A filter is disposed within the auxiliary water reservoir.

Abstract: An ice making assembly includes an ice mold and a pump assembly for urging an ice-building spray into the ice mold to form an ice billet. A controller operates the pump assembly to provide the ice-building spray at a first flow rate until the ice billet reaches a predetermined thickness and then operates the pump assembly to provide the ice-building spray at a second flow rate that is less than the first flow rate.

Abstract: A refrigerator appliance or ice making assembly, as provided herein, may include a body and an ejector. The body may include an ice mold for receiving and freezing water. The ice mold may define a discrete first compartment and second compartment within which water freezes. The first compartment may define a first cube profile. The second compartment may be axially-spaced apart from the first compartment and define a second cube profile. The second cube profile may be different from the first cube profile. The ejector may be rotatably disposed above the first cube profile and the second cube profile to motivate ice from the first and second compartments.

Abstract: A refrigerator appliance or ice supply, as provided herein, may include an ice maker, an ice bucket, and a shutter. The ice maker may include a mold body defining a discrete first compartment and second compartment within which water freezes. The ice bucket may define a first chamber and a second chamber. The second chamber may be separated from the first chamber. The ice bucket may further define an outlet opening having a first portion in fluid communication with the first chamber and a second portion in fluid communication with the second chamber. The shutter may be disposed at the outlet opening and movable between a first position and a second position. The first position may include the shutter covering the second portion and spaced apart from the first portion. The second position may include the shutter covering the first portion and spaced apart from the second portion.

Abstract: An ice bucket for a refrigerator appliance, includes a bucket body; an auger provided inside the bucket and including an auger shaft rotatable about a first shaft axis and a collet at a first end of the auger shaft and including an axially beveled surface formed circumferentially around the auger shaft; and an agitator provided in the bucket in mechanical communication with the auger, the agitator including an agitator shaft rotatable about a second shaft axis non-parallel to the first shaft axis, a plurality of first tines extending radially from the agitator shaft within the bucket body to engage ice therein, and a projection that extends perpendicularly from the agitator shaft opposite the plurality of tines. The projection engages with the axially beveled surface to oscillate the agitator.
