    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.

    Abstract: A refrigerator according to the present invention comprises: a storage compartment for storing food; a first temperature sensor for sensing the temperature in the storage compartment; a door for opening and closing the storage compartment; a cold air supply means for supplying cold air into the storage compartment; trays forming ice-making cells which are spaces in which water changes phase into ice due to the cold air; a second temperature sensor for sensing the temperature of the water or ice in the ice-making cells; a heater for supplying heat to the trays; and a control unit for controlling the heater, wherein, after opening or closing of the door is sensed during the ice-making process, the control unit increases the cooling power of the cold air supply means if an increase in cooling power therefrom is determined to be needed on the basis of the temperature sensed by the first temperature sensor, and decreases the amount of heat applied by the heater if a reduction in heat applied by the heater is determined to be needed on the basis of the change in temperature sensed by the second temperature sensor.

    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.

    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 par having a shape corresponding to the ice making cell and a second part extending from a certain point of the first part so as to support one of the first tray and the second tray.
