Document Type and Number:
WIPO Patent Application WO/2020/071773
Kind Code:
A1
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 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, which constitutes another part of the icing cell, can come into contact with the first tray in an icing step, and can be separated from the first tray in an ice separating step; a water supply valve for adjusting the flow of water to be supplied to the icing cell; a water supply amount detection unit for detecting a water supply amount for the icing cell; and a control unit for controlling the water supply valve, wherein the control unit controls the water supply valve so as to supply water to the icing cell in a reference water supply amount in order to supply water to the icing cell at a water supply position of the second tray, moves the second tray to an icing position after finishing the water supply in the reference water supply amount, determines, by means of the water supply amount detection unit, whether a water supply amount for the icing cell reaches a target water supply amount, starts icing when the water supply amount for the icing cell reaches the target water supply amount, and moves the second tray to the water supply position again and then controls the water supply valve so as to supply water in an additional water supply amount that is less than the reference water supply amount, when the water supply amount for the icing cell does not reach the target water supply amount.
