Refrigerator and method for controlling same

Abstract

A refrigerator of the present invention may comprise: an ice maker including an ice making cell; a heater for supplying heat to the ice making cell during an ice making step; and a controller for controlling the heater. The controller can control the cooling power of the cooler to be greater, when a spatial temperature, detected during the ice making step by a temperature sensor for detecting the temperature of a space in which the refrigerator is installed, is greater than or equal to a critical temperature, than the cooling power of the cooler when the spatial temperature is less than the critical temperature. The controller can control the heating amount of the heater to be greater, when the spatial temperature detected during the ice making step by the temperature sensor is greater than or equal to the critical temperature, than the heating amount of the heater when the spatial temperature is less than the critical temperature.

Description

technical field [0001] This instruction relates to a refrigerator and a control method thereof. 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. [0003] 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. [0004] The ice made in the ice maker with the above-mentioned structure has a flat surface at least on one side,...

AI Technical Summary

Problems solved by technology

[0014] However, according to Conventional Document 2, the heating amount of the heater is simply increased when the volume of water decreases, so it is difficult to produce ice with uniform transparency depending on the form of ice.

[0015] In addition, in the case of conventional document 2, the structure and heater control logic for producing highly transparent ice regardless of the accessibility of the space where the ice making device is located cannot be disclosed.
