Abstract
Ice making system and method for a refrigerator is disclosed. The ice making system includes an ice making unit that makes ice cubes, a cold air generator that cools air inside a cooling duct so as to produce cold air, a cold air circulation unit that supplies the cold air from the cold air generator to the ice making unit, and discharges the cold air from the ice making unit to the cold air generator, and a cold air guiding unit that circulates the cold air inside the ice making unit.
Claims17
An ice making system for a refrigerator, the ice making system comprising:
- an ice making unit that makes ice cubes;
- a cold air generator that cools air inside a cooling duct so as to produce cold air;
- a cold air circulation unit that supplies the cold air from the cold air generator to the ice making unit and discharges the cold air from the ice making unit to the cold air generator;
- and
- a cold air guiding unit that circulates the cold air inside the ice making unit,
- wherein the cold air guiding unit comprises:
- a main guide that introduces the cold air from the cooling duct into the cold air guiding unit;
- a first sub-guide that extends upward from the main guide so as to guide the cold air upward to a position above an ice maker of the ice making unit;
- and
- a second sub-guide that extends downward from the main guide so as to guide the cold air downward to a position below the ice maker of the ice making unit.
An ice making method for a refrigerator, the method comprising:
- cooling air using a cooling duct so as to produce cold air;
- supplying the cold air to an ice making unit so as to make ice cubes;
- circulating the cold air in the ice making unit;
- discharging the cold air from the ice making unit to the cooling duct;
- and
- cooling the discharged cold air again in the cooling duct, wherein said circulating the cold air in the ice making unit further comprises:
- guiding the cold air to a position above an ice maker of the ice making unit and to a position below the ice maker.
A refrigerator, comprising:
- a freezer compartment located within a main body of the refrigerator;
- a refrigeration compartment located within the main body of the refrigerator, wherein the freezer compartment is located below the refrigeration compartment;
- an ice making unit that makes ice cubes;
- a cold air generator that cools air inside a cooling duct so as to produce cold air;
- a cold air circulation unit that supplies the cold air from the cold air generator to the ice making unit and discharges the cold air from the ice making unit to the cold air generator;
- and
- a cold air guiding unit that circulates the cold air inside the ice making unit, wherein the cold air guiding unit comprises:
- a main guide that introduces the cold air from the cooling duct into the cold air guiding unit;
- a first sub-guide that extends upward from the main guide so as to guide the cold air upward to a position above an ice maker of the ice making unit;
- and
- a second sub-guide that extends downward from the main guide so as to guide the cold air downward to a position below the ice maker of the ice making unit.
