Problems solved by technology

[0005] However, such supercooling-related technologies are not easily applied to the production of ice for eating and drinking.
The use of nucleating agents has limitations in the preparation of catering ice and may not be appropriate in some cases
When considered at the level of water intake, the inclusion of additives rather than pure crushed ice may be objectionable to consumers
[0006] In addition, it is expected that it will be difficult to find an additive that has a certain supercooling prevention effect and is not harmful to the human body, and it is accompanied by the inconvenience of storing the nucleating agent in the refrigerator and injecting it when making ice.

Embodiment Construction

[0049] 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.

[0050] 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 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 ...
