Abstract

A refrigerator of the present invention comprises: storage chambers for storing food; a cooler for supplying cold to the storage chambers; a first tray assembly for forming a portion of an ice-making cell, which is the space in which water phase-changes into ice by the cold; a second tray assembly for forming another portion of the ice-making cell; a heater positioned adjacently to the first tray assembly and / or the second tray assembly; and a control unit for controlling the heater, wherein the control unit turns on the heater in at least a portion of a section while the cooler supplies cold, so that bubbles dissolved in the water inside the ice-making cell move toward liquid water from a portion in which ice is formed, thereby enabling clear ice to be formed, and the control unit increases the heating rate of the heater when the heat transfer rate between the cold inside the storage chambers and the water of the ice-making cell is increased, and reduces the heating rate of the heater when the heat transfer rate between the cold inside the storage chambers and the water of the ice-making cell is reduced, so that the ice-making speed of the water inside the ice-making cell can be maintained within a predetermined range that is lower than the ice-making speed when ice making is performed while the heater is turned off.

Description

technical field

[0001] This instruction manual refers to refrigerators. Background technique

[0002] In general, a refrigerator is a home appliance capable of storing food at a low temperature in an internal storage space shielded by a door. The refrigerator cools the inside of the storage space by using cold air, and can preserve the stored food in a refrigerated or frozen state. Generally, an ice maker for making ice is provided in the refrigerator. The ice maker accommodates water supplied from a water supply source or a water tank behind a tray, and generates ice by cooling the water. In addition, the ice maker can remove the ice that has been made from the ice tray by heating or twisting. The ice maker that automatically supplies water and removes ice as described above is formed so as to open upward to hold molded ice. The ice made in the ice maker with the above-mentioned structure has a flat surface at least on one side, such as a crescent shape or a cube shape....
