Title:
REFRIGERATOR
Document Type and Number:
WIPO Patent Application WO/2020/071771
Kind Code:
A1
Abstract:
The refrigerator of the present invention comprises: a storage chamber for storing food; a first ice-maker comprising a tray assembly which forms an ice-making cell in which space water undergoes a phase change into ice due to the cold; a second ice-maker arranged in an ice-making chamber which is partitioned from the storage chamber; a cooler for supplying the cold to the storage chamber and the ice-making chamber; an ice bin for storing ice generated by the second ice-maker; a water supply unit for supplying water to the ice-making cell; a heater for supplying heat to the ice-making cell; and a controller for controlling the heater. The controller turns on the heater in at least some period while the cooler is supplying the cold, so that bubbles dissolved in the water in the ice-making cell move toward the water in a liquid state from a portion where the ice is generated and transparent ice can be generated. In addition, in order for the speed of the ice-making using the water in the ice-making cell to be maintained within a predetermined range less than the speed of the ice-making when the ice-making is performed as the heater is turned off, the controller increases the heating amount of the heater when the heat transfer amount between the cold in the storage chamber and the water in the ice-making cell is increased, and decreases the heating amount of the heater when the heat transfer amount between the cold in the storage chamber and the water in the ice-making cell is reduced.
