AI Technical Summary

Technical Problem

Ice makers that make spherical ice are bulky due to multiple components, limiting installation location and causing a loss of storage space, and there are challenges with cold air flow, water supply, and ice extraction integration in refrigerators.

Method used

A refrigerator design that integrates cold air flow, water supply, and ice extraction with a structure that includes a first tray made of metal, a second tray movable relative to the first tray, a cover guiding cold air flow, and a duct part communicating with the ice-making compartment, along with a water supply part and ejector for ice separation, all within a compact ice-making compartment.

Benefits of technology

The design ensures uniform cooling of all cells, prevents water leakage, simplifies the structure, and improves cooling efficiency by exposing cell extension parts to cold air, facilitating efficient ice-making and extraction.

Abstract

The present disclosure relates to a refrigerator, and the refrigerator includes a cabinet provided with an evaporator and having a storage space; a door configured to open and close the storage space; an ice-making compartment provided at the door and supplied with cold air from the evaporator; and an ice maker provided in the ice-making compartment, in which the ice maker includes a first tray made of a metal material and having a plurality of first cells; a second tray movably mounted relative to the first tray and having a plurality of second cells that is in contact with the first cells to form a space where ice is made; a drive part configured to move the second tray; and a cover mounted on the first tray and forming a cold air flow passage passing on the first tray, and the cover is in communication with a cold air inlet formed in the ice-making compartment and guides cold air into the cold air flow passage.
