Ice maker for refrigerator and manufacturing method for the same

A method for manufacturing an ice maker for a refrigerator, the method comprising:

• forming a case for protecting a cooling space into which cold air is supplied;
• forming an ice making assembly for making ice using the cold air;
• forming an ice bucket including a plurality of ribs formed on an outer circumferential surface thereof and being configured to be operable for containing the ice made by the ice making assembly in the cooling space;
• assembling the ice bucket to be placed at a bottom of the cooling space for accumulating the ice made by the ice making assembly placed at a top of the cooling space, and
• providing a cold air ventilation path between the case and the outer circumferential surface of the ice bucket in the cooling space for guiding the cold air to flow along the outer circumferential surface of the ice bucket,
• wherein the cold air ventilation path is formed as a furrow that guides a flow of the cold air between the contiguous ribs on the outer circumferential surface of the ice bucket, and
• wherein the ribs are formed on the outer circumferential surface to extend in a same direction as a direction in which the ice bucket slides when the ice bucket is pushed into the case and when the ice bucket is pulled out from the case.

A refrigerator, comprising:

• a refrigerator compartment;
• a freezer compartment coupled to the refrigerator compartment;
• and
• an ice maker in the refrigerator compartment and coupled to the freezer compartment, the ice maker comprising:
• a case enclosing a cooling space into which cold air is supplied;
• an ice making assembly operable for making ice using the cold air;
• an ice bucket including a plurality of ribs formed on an outer circumferential surface thereof and being configured to be operable for containing the ice made by the ice making assembly in the cooling space;
• and
• a cold air ventilation path provided between the case and the outer circumferential surface of the ice bucket and being configured to guide the cold air to flow along the outer circumferential surface of the ice bucket in the cooling space,
• wherein the cold air ventilation path is formed as a furrow that guides a flow of the cold air between the contiguous ribs on the outer circumferential surface of the ice bucket, and
• wherein the ribs are formed on the outer circumferential surface to extend in a same direction as a direction in which the ice bucket moves when the ice bucket is pushed into the case and when the ice bucket is pulled out from the case.
