Benefits of technology

[0006]Therefore, to solve the problems of the related art ice maker for a refrigerator, an object of the present invention is to provide an ice maker for a refrigerator capable of enhancing an icing speed.

Problems solved by technology

Accordingly, a loss occurs due to a convection heat transfer, which lowers icing speed.
Furthermore, water supplied to the ice making tray contains a certain amount of air.
As a result, such air bubble in the water is not discharged outwardly but remains, which causes a generation of opaque ice.

Embodiment Construction

[0017]Hereinafter, description will be given in detail of a refrigerator according to the present invention with reference to the accompanying drawings.

[0018]FIG. 1 is a perspective view showing a three-door bottom freezer type refrigerator having an ice maker according to the present invention.

[0019]As shown in FIG. 1, the refrigerator according to the present invention may include a refrigerating chamber 2 disposed at an upper side of a refrigerator main body 1 for storing foods in a fresh state, and a freezing chamber 3 disposed at a lower side of the refrigerator main body 1 for storing foods in a frozen state. The refrigerator main body 1 is provided with a refrigerating chamber door 4 and a freezing chamber door 5 respectively for opening / closing the refrigerating chamber 2 and the freezing chamber 3. A machine room (not shown) in which a compressor 10 (shown in FIG. 2 or the like) and a condenser 20 (shown in FIG. 2 or the like) are disposed is formed at a lower end portion o...

Abstract

Disclosed is an ice maker for a refrigerator. The ice maker is further provided with an ice making evaporator in addition to an evaporator for cooling a refrigerating chamber of a freezing chamber, and the ice making evaporator is sunk in water to generate ice, thereby quickly creating transparent ice. The ice maker can also be disposed in the refrigerating chamber or a refrigerating chamber door, thus to prevent ice from being formed with air bubble remaining in water, resulting in enhancing transparency of ice. In addition, even if the ice maker is disposed in the refrigerating chamber door, cold air is not needed to be induced from the freezing chamber, which allows independent operations of the freezing chamber and the ice maker, thereby increasing energy efficiency.

Description

TECHNICAL FIELD [0001]The present invention relates to an ice maker employed in a refrigerator.BACKGROUND ART[0002]In recent time, large-sized refrigerators are provided with ice makers therein for making ice pieces. The ice maker is configured such that a certain amount of water supplied in an ice making tray is iced by applying cold air and then the ice in the tray is carried to an ice storing container for storage.[0003]In such ice maker, the ice making tray is disposed under a condition having an ice point (freezing point) lower than 0° C., such as a freezing chamber, so as to freeze water by cold air. Hence, a portion where cold air first reaches starts to be iced, and such icing is advanced toward a central direction. For example, the is surface of the water which is first contacted by its surrounding cold air start to be iced to form a core of ice. Such icing is in progress toward the center of the water once the core of ice is formed, thereby generating ice eventually.[0004]...
