Ice making apparatus and refrigerator having the same

Abstract

An ice making apparatus capable of reducing an ice making time be rapid cooling of an ice making tray thereof while guaranteeing the making of transparent ice and a refrigerating having the ice making apparatus. The ice making apparatus includes the ice making tray to freeze water filled therein so as to make ice, and a cold air guiding device to guide cold air to a lower surface of the ice making tray. The cold air guiding device includes a cold air guiding plate installed below the ice making tray to be spaced apart from the lower surface of the ice making tray, and a plurality of protrusions provided at an upper surface of the cold air guiding plate to guide the cold air flowing along the upper surface of the cold air guiding plate in a direction toward the lower surface of the ice making tray.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This application claims the benefit of Korean Patent Applications No. 10-2006-0076434, filed on Aug. 11, 2006 and No. 10-2007-0054431, filed on Jun. 4, 2007 in the Korean Intellectual Property Office, the disclosures of which are incorporated herein by reference.BACKGROUND OF THE INVENTION[0002]1. Field of the Invention[0003]The present invention relates to an ice making apparatus for the making of ice and a refrigerator having the ice making apparatus. More particularly, to an ice making apparatus which can achieve an improvement in the ice making performance thereof by virtue of rapid cooling of an ice making tray, and a refrigerator having the ice making apparatus.[0004]2. Description of the Related Art[0005]Korean Patent Registration Publication No. 10-0565621 discloses a conventional refrigerator having an upper refrigerating compartment and a lower freezing compartment. The refrigerator further includes an ice making chamber provide...

AI Technical Summary

Benefits of technology

[0010]Accordingly, it is an aspect of the present invention to provide an ice making apparatus, which can achieve a reduced ice making time by virtue of rapid cooling of an ice making tray thereof, and a refrigerator having the ice making apparatus.

[0011]It is another aspect of the present invention to provide an ice making apparatus, which can achieve rapid removal of residual heat in an ice making tray after separation of ice, and a refrigerator having the ice making apparatus.

[0012]It is yet another aspect of the present invention to provide an ice making apparatus, which can guarantee the making of transparent ice by allowing water received in an ice making tray to be gradually frozen from the bottom to the top, and a refrigerator having the ice making apparatus.

Problems solved by technology

The above-described conventional refrigerator has a problem in that it requires an excessively long time to make ice because an ice making operation must be performed only after an interior temperature of the ice making chamber drops by cold air supplied there to until it reaches a desired freezing condition.

Specifically, the conventional refrigerator has a problem in that an excessively long time is required for the cooling of the ice making tray.
