Problems solved by technology

[0015] However, according to Conventional Document 2, when the volume of water simply decreases, the amount of heating of the heater is increased, so it is difficult to produce ice with uniform transparency depending on the shape of the ice.

Embodiment Construction

[0088] Hereinafter, some embodiments of the present invention will be described in detail with reference to illustrative drawings. When assigning reference numerals to constituent elements in each drawing, the same constituent elements are assigned the same reference numerals as much as possible even if they are shown in different drawings. Also, in describing the embodiments of the present invention, if it is judged that specific descriptions of related known structural elements or their functions affect understanding of the embodiments of the present invention, detailed descriptions thereof will be omitted.

[0089] Also, terms such as first, second, A, B, (a), (b), etc. may be used in describing structural elements of the embodiments of the present invention. Such terms are only for distinguishing the structural elements from other structural elements, and the nature, sequence or order of the corresponding structural elements are not defined by the terms. When it is descri...

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.

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. 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. [0003] The ice maker can remove ice after ice making from the ice tray by heating or twisting. [0004] The ice maker, which automatically supplies water and removes ice, is formed to open upward to hold molded ice. [0005] 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 c...
