Refrigerator

Abstract

A refrigerator includes an ice-making unit disposed in the door and can make ice through direct cooling by a refrigerant without using cold air flow. A cold air generation system operates to circulate the refrigerant for supplying a cold air flow for the refrigerator. A refrigerant pipe is installed in the refrigerator main body to branch off some refrigerant from the cold air generation system. An ice-making pipe is installed within the ice-making unit and receives the refrigerant from the refrigerant pipe. Water freezes into ice through heat transfer between the ice-making unit and the ice-making pipe containing refrigerant. A soft pipe is disposed around a hinge shaft of the refrigerator main body and the door and configured to interconnect the ice-making pipe and the refrigerant pipe in a twistable manner.

Description

technical field [0001] The present disclosure relates to refrigerators, and more particularly, to ice making devices in refrigerators. Background technique [0002] In general, a refrigerator is a device for storing various items such as food at a low temperature. The low temperature in the refrigerator is achieved by circulating cold air, which can be continuously generated through a heat exchange process by using a refrigerant. During operation, the refrigerant undergoes a repeated cycle of compression, condensation, expansion and evaporation. [0003] The main body of the refrigerator may have a rectangular parallelepiped shape with an open front surface. Typically, the main body encloses a refrigerated compartment or a refrigerated compartment and a freezer compartment, each having its own door. Refrigerators can include multiple drawers, shelves, vegetable compartments, etc. for sorting and storing different types of items. [0004] Conventionally, a top-mounted ref...

AI Technical Summary

Problems solved by technology

Therefore, the water in the refrigerator door cannot be directly cooled by the refrigerant, and the ice-making efficiency is low
