Abstract

A refrigerator of the present invention comprises: a first tray for forming a part of an ice-making cell; a second tray for forming another part of the ice-making cell; a tray temperature sensor for detecting a temperature of the ice-making cell; an electric discharge spark generator located around any one of the first tray and the second tray and provided with an electrode; and a controller for controlling the electric discharge spark generator to generate a spark in the electrode when water in the ice-making cell is determined to be in an overcooling state on the basis of the temperature measured by the tray temperature sensor.

Description

technical field

[0001] The present invention relates to a refrigerator and a control method thereof. Background technique

[0002] When supercooling occurs in the process of freezing water, it will cause a sharp phase transition and produce opaque ice. Supercooling refers to a state in which phase transition is not caused and latent heat is not released at a temperature below the freezing point. Opaque ice is easily observed when freezing ice in a freezer, which is the result of blurred freezing of water in a supercooled state due to a sharp phase transition. In order to control the transparency of the ice, it is especially important to regulate the supercooling. In order to make transparent ice, it is necessary to provide a way to relieve or prevent supercooling.

[0003] In general refrigerators, it is not easy to find a technology that takes supercooling of water into consideration for ice production. It can be understood that the development of ice-making technology ...
