Abstract: A refrigerator includes a freezing compartment and a refrigerating compartment, a refrigerating compartment door, an ice maker disposed in the freezing compartment, and an ice bank disposed on the door. The refrigerator also includes an ice transfer device configured to transfer ice made by the ice maker to the ice bank through an ice chute. The ice transfer device includes a housing and a transfer member configured to transfer ice from the housing into the ice chute. An inlet end of the ice chute is located at a point that is spaced upward from a bottom surface of the housing and extends upward from a horizontal plane at an angle that is less than an angle between the horizontal plane and a tangent that passes through an outer circumferential surface of the housing at a lower end of the inlet end of the ice chute.

Abstract: A refrigerator according to the present invention comprises: a storage space in which food is stored; a cooler for supplying cold to the storage space; a first tray assembly constituting a part of an icing cell which is the space in which water is phase-changed to ice by the cold; a second tray assembly constituting another part of the icing cell; a heater located to be adjacent to the first tray assembly and/or the second tray assembly; and a control unit for controlling the heater, wherein the control unit performs controls so that the heater is turned on in at least a partial period while the cooler supplies the cold, and thus air bubbles disintegrating in the water inside the icing cell move to liquid-phase water from a part where ice is generated, thereby enabling transparent ice to be generated, and the degree of cold transfer, which is the amount of cold of the cooler is to be transferred, is different in the first tray assembly and the second tray assembly.

IPC: F25C1/10
Abstract: A refrigerator according the present disclosure includes a first tray configured to form a portion of an ice making cell, a second tray configured to form another portion of the ice making cell and capable of moving relative to the first tray, a driver configured to move the second tray, a temperature sensor configured to sense the temperature of water or ice in the ice making cell, and a controller configured to control the driver, in which when it is determined that the water in the ice making cell is in a supercooled state based on the temperature measured by the tray temperature sensor, the controller may operate the driver to move the second tray.

Abstract: A refrigerator includes a storage chamber, a cooler configured to supply cold, a tray defining an ice making cell, a liquid supply configured to supply liquid, a temperature sensor, a heater configured to supply heat, and a controller configured to control the heater. The controller controls the heater to be turned on during ice making to make transparent ice. The controller variably controls a heating amount of the heater so that an ice making rate is maintained within a predetermined range. When a defrosting start condition is satisfied in the ice making process, the controller performs a defrosting process.
