AI Technical Summary

Technical Problem

Existing ice makers struggle to produce transparent ice with uniform transparency and shape, as heat transfer between trays in the ice making process leads to uneven ice formation and reduced transparency due to bubble entrapment.

Method used

A refrigerator design featuring a first and second tray assembly, where the second tray is closer to the heater, and a pusher mechanism to facilitate ice separation, with a configuration that enhances deformation resistance and heat transfer control to direct ice formation towards the second tray, ensuring uniform transparency and shape.

Benefits of technology

The solution effectively produces transparent ice with uniform transparency and shape by controlling heat transfer and deformation resistance, reducing bubble entrapment and enhancing ice formation directionality.

Abstract

The refrigerator according to the present invention may comprise: a first tray forming a part of ice-making cells; and a second tray assembly forming the other part of the ice-making cells. The first tray assembly comprises a first tray and a first tray case which supports the first tray, and the second tray assembly comprises a second tray and a second tray case which supports the second tray, and the degree of adhesion of ice to any one of the first and second trays is smaller than the degree of adhesion of ice to any one of the first and second tray cases or the degree of adhesion of ice to a metal.
