A refrigerator includes a cabinet with one or more food compartments and one or more doors closing the food compartments and an ice maker located in the cabinet to produce ice. The ice maker includes a mold body for forming ice, the mold body having multiple cups, where each cup has an opening for receiving water to be frozen within the cup. The mold body is divided into at least a first zone and a second zone and the ice maker including at least a first heater and a second heater configured to provide heat to the first and second zones of the mold body, respectively, and a controller configured to harvest ice from the first zone independently of the second zone by actuating the first heater to provide heat to the first zone of the mold body to facilitate a release of ice from the first zone.

An ice maker includes: an upper tray defining an upper chamber that is a portion of an ice chamber, where an upper opening is provided in an upper side of the upper tray; a lower tray defining a lower chamber that is another portion of the ice chamber; a lower support supporting the lower tray and provided with a lower heater; and a control unit configured to operate the lower heater in an ice making process. The control unit variably controls an output of the lower heater so that bubbles included in water in the ice chamber are gathered in a lowermost section in the ice making process.

An ice maker includes a carriage, an ice mold defining a plurality of cavities that is movably coupled to the carriage such that the ice mold is movable relative to the carriage between a home position and a harvest position, and a detection lever movably coupled to the carriage such that the detection lever is movable between a retracted position and an extended position, the detection member being biased toward the extended position. The ice maker further includes a retention mechanism configured to retain the detection lever in the retracted position when the ice mold is in the harvest position.

An ice dispenser includes an ice chute, an ice maker chute plate, and a vent wall. The ice chute is mounted adjacent an ice dispenser window and is configured to receive ice when the ice is pushed through the ice dispenser window. The ice maker chute plate includes an ice chute aperture wall configured to receive and to dispense the ice from the ice chute. The ice chute is mounted to extend from the ice maker chute plate. The vent wall is mounted to the ice maker chute plate. The vent wall includes an aperture wall through which air from a cooling system is received onto the ice chute when the cooling system is operated.

An ice maker of the present invention comprises: an upper tray defining an upper chamber that is a portion of an ice chamber, wherein an upper opening is provided in an upper side of the upper tray; a lower tray defining a lower chamber that is another portion of the ice chamber; a lower support supporting the lower tray and provided with a lower heater; and a control unit configured to operate the lower heater in an ice making process, wherein the control unit variably controls an output of the lower heater so that bubbles included in water in the ice chamber are gathered in a lowermost section in the ice making process.

According to an embodiment of the present disclosure, a method for controlling a refrigerator, the refrigerator including an ice mater including a first tray and a second try provided in a storage space and coupled to each other to define a ice chamber and a driving part that rotates the second tray, a first heater provided in the first tray to heat the first tray, a second heater provided in the second tray to heat the second tray, and an ejector provided below the second tray to press an external portion of the second tray to separate ice from the second tray when the second tray is rotated for ice separation, and a controller that controls operation of the ice maker, the method including starting ice making by supplying water to the ice chamber; heating the second tray by turning on the second heater during ice making; heating the first tray by turning on the first heater for ice separation after completion of ice making; and heating the second tray by turning on the second heater for ice separation.

The present disclosure relates to an ice maker and a refrigerator having the ice maker. An ice maker according to the present disclosure includes: an upper assembly including an upper tray forming an upper chamber, which is a portion an ice chamber, and having an upper opening, and a temperature sensor configured to sense temperature of the ice chamber in contact with the upper tray; and a lower assembly being rotatable with respect to the upper assembly and having a lower tray forming a lower chamber that is another portion of the ice chamber, in which a contact portion between the temperature sensor and the upper tray is positioned closer to a contact surface of the upper tray and the lower tray than the upper opening.

An ice maker for a refrigeration appliance, the ice maker including an ice maker frame and an ice tray housed within the ice maker frame and configured to form ice pieces therein. An air handler is disposed adjacent the ice maker frame and an ice maker fan is disposed within the air handler and is configured to direct cooled airflow out of the air handler and into the ice maker frame. A controller is configured to operatively control the ice maker during an ice making cycle. The ice maker is operable in a first mode and a second mode. When the ice maker is operated in the second mode, the ice maker fan is cycled on and off during predetermined time intervals in order to produce clear ice pieces.

Ice making appliances and methods for making ice using a machine-readable ice cube mold are provided herein. The ice making appliances and methods of making ice may include obtaining ice mold identifier data from the ice mold. Ice mold identifier may be used to acquire operating parameters of the ice making appliance specific to that ice mold from an external communication network. The operating parameters may be used to adjust operation of the appliance, such as the volume of water to dispense for that particular mold.

An ice maker of the present invention comprises: an upper tray defining an upper chamber that is a portion of an ice chamber, wherein an upper opening is provided in an upper side of the upper tray; a lower tray defining a lower chamber that is another portion of the ice chamber; a lower support supporting the lower tray and provided with a lower heater; and a control unit configured to operate the lower heater in an ice making process, wherein the control unit variably controls an output of the lower heater so that bubbles included in water in the ice chamber are gathered in a lowermost section in the ice making process.
