Abstract: 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.

IPC: F25C1/04
Abstract: A method controls a refrigerator including first and second trays defining an ice chamber, a driving unit for moving the second tray, an ice bin for storing ice produced in the ice chamber, and an ice-fullness detection means for detecting whether or not the ice bin is full of ice. The method includes supplying water to the ice chamber when the second tray is at a water-supply position, making ice after the second tray has moved to an ice-making position in an inverse direction after the water supply has been completed, determining whether the ice bin is full of ice after the ice making is completed, moving the second tray to an ice-separating position and then rotating in the inverse direction if it is not determined whether or not the ice bin is full of ice, and determining again whether the ice bin is full of ice after ice separation is completed.

Abstract: An ice maker of a refrigerator includes a tray assembly having an upper tray that defines upper portions of a plurality of ice making chambers. Each of the plurality of ice making chambers is configured to receive water and generate an ice piece. The tray assembly also includes a lower tray that is located vertically below the upper tray, that is configured to rotate relative to the upper tray, and that defines lower portions of the plurality of ice making chambers, wherein at least one of the upper tray or the lower tray comprises a flexible tray made of a flexible material. Additionally, a case is configured to accommodate the flexible tray to restrict a deformation of the flexible tray. A heater that is located between the case and the flexible tray is configured to supply heat to the plurality of ice making chambers through the flexible tray.
