ICE MAKING MACHINE OF A REFRIGERATOR FOR SHORTENING ICE-MAKING TIME BY MAKING AN ICE TRAY FROM FLEXIBLE HEAT-CONDUCTIVE MATERIALS AND INJECTING THE WATER INTO THE TRAY WHILE COOLING THE ICE TRAY IN ADVANCE

摘要

PURPOSE: An ice making machine of a refrigerator is provided to reduce time and power for heating and cooling an ice tray without using a heater for separating ice from the ice tray and to control temperature of a freezer compartment within a constant range. CONSTITUTION: An ice making machine of a refrigerator is composed of an ice tray(50) rotatively supported to a freezer compartment or a door, made from flexible and heat-conductive materials, and composed of an ice making chamber(51) therein and a corrugated stress relieving unit(52a) formed where stress is concentrated in twisting and a motor unit connected to the other side of the ice tray to transmit driving force, to separate ice from the ice tray in twisting the ice tray by the driving force, and to discharge ice of the ice making chamber to an ice bank by rotating the ice tray.
