A refrigerant of relatively low temperature flows through the refrigerant pipe to cause ice to be formed on surfaces thereof. A heater may be provided on the refrigerant pipe and operated during an ice-releasing process. This system and method may eliminate the need for an additional duct to supply cold air to the ice maker, thus simplifying a manufacturing process and reducing manufacturing costs.

  • Patent number: 8405002
    Abstract: An icemaker and a refrigerator having an icemaker are discussed. The icemaker has pulse-electrothermal ice release and includes an ice-making tray having several ice forming portions in which water is stored and ice is formed; and a housing surrounding the ice-making tray provided with at least one cold air inlet and/or ice ejection port through which cold air is supplied and ice released along a bent channel. The cold air inlet and/or ice ejection ports are baffled to prevent contact with a user's fingers and thereby reduce the possibility of electric shock.

  • Publication number: 20120318004
    Abstract: Disclosed are an ice maker, a refrigerator having the ice maker, and a method for supplying ice of the refrigerator. An ice making container long in a vertical direction is installed on a side wall surface of a refrigerator door, makes ice, and pushes up the ice by screws to release the ice, whereby the size of the ice maker can be reduced, the area occupied by the ice maker can be reduced, and a refrigerator having the ice maker can become slimmer. Also, because an installation height of the ice maker is lowered to shorten a cold air supply path and prevent a loss in the process of supplying cold air to the ice making chamber. Also, because a cutting operation is performed simultaneously when the ice is lifted, a fabrication cost can be reduced and a defective state due to malfunction can be prevented.
