Abstract: A refrigerator according to the present invention may comprise a first tray assembly forming one part of ice-making cells, and a second tray assembly forming the other part of same. Any one tray assembly, from among the first and second tray assemblies, comprises a first part forming at least a part of the ice-making cells, and a second part extending from a set point on the first part so as to reduce water supplied to the ice-making cells from leaking through a space between the first and second tray assemblies.

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.

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 an ice making cell; and a second tray assembly forming another part of the ice making cell. The first tray assembly includes a first tray defining a part of the ice making cell and a first tray case supporting the first tray, and the second tray assembly includes a second tray defining another part of the ice making cell and a second tray case supporting the second tray. One of the first and second tray cases includes a first region having a through-hole and a second region having a shape corresponding to the ice making cell to support one of the first and second trays.

Abstract: A refrigerator according to the present invention includes a storage chamber configured to store food, a cold air supply part configured to supply cold air to the storage chamber, a tray configured to form an ice making cell being a space in which water is phase-changed into ice by the cold air, a temperature sensor configured to sense the temperature of water or ice in the ice making cell, a heater configured to provide heat to the tray, and a controller configured to control the heater, in which the controller controls the heater to be turned on so that ice can be easily separated from the tray when the ice making is completed, and the controller controls the heater to be turned off when a temperature sensed by the temperature sensor reaches a first turn-off reference temperature greater than zero after a first reference time elapses in a state in which the heater is turned on.
