Abstract: A refrigerator includes a main body defining a storage compartment, a door, an ice making device, a water tank disposed for supplying water into the ice making device, and an ice bin to receive and store ice pieces made in the ice making device. The ice making device includes an ice making tray having ice making chambers configured to be filled with water for making the ice pieces, and an ejector extending from an upper central portion of the ice making tray in a longitudinal direction of the ice making tray to pass through both ends of the ice making tray. The ejector is configured to be maintained in a fixed state during water supply, ice making, and ice separation processes, and the ice making tray is configured to rotate at an angle of about 360° in one direction with respect to the ejector.

Abstract: A method for controlling a refrigerator includes starting water supply to an ice making device in a refrigerator. The ice making device includes a flow sensor configured to detect water supply flow to the ice making device by using a pulse value according to rotation of an impeller. The method also includes operating the flow sensor to detect a pulse value, determining whether the pulse value has reached a target pulse value within a preset time, and, based on a determination that the detected pulse value has not reached the target pulse value within the preset time, determining that water supply to the ice making device is in a low water-pressure state and performing a water supply control process according to the low water-pressure state.

Abstract: A refrigerator may include: a first tray forming a part of ice-making cells; a second tray forming the other part of the ice-making cells; a heater for supplying heat to the ice making cells; a cooler for supplying cold to a storage compartment; and a control unit for controlling the heater and the cooler. The operation modes of the refrigerator include a first mode and a second mode. The control unit may control so that either or both of the amounts of cooling by the cooler and the amount of heating by the heater vary in the first mode and the second mode.

Abstract: The present invention relates to a refrigerator. A refrigerator of the present invention may comprise: a first tray assembly forming a part of ice-making cells; a second tray assembly forming the other part of the ice-making cells; and a heater. In order to reduce the transfer heat, which is transferred from the heater to any one of the first and second tray assemblies, to ice-making cells formed by the other tray assembly, the one tray assembly may comprise a first part forming at least a part of the ice-making cells. The degree of heat transfer of the first part may vary along the outer circumferential surfaces of the ice-making cells.

Abstract: A refrigerator includes an ice maker, which includes an ice making cell, a heater configured to supply heat to the ice making cell during an ice making process, and a controller configured to control the heater. A cooling power of the cooler when a temperature sensed by a temperature sensor is greater than or equal to a limit temperature during an ice making process is greater than a cooling power of the cooler when the temperature is less than the limit temperature. A heating amount of the heater when the temperature sensed by the temperature sensor is greater than or equal to the limit temperature during the ice making process is greater than a heating amount of the heater when the temperature is less than the limit temperature.
