Publication number: 20120324918Abstract: A refrigeration system for a refrigerator having a freezer compartment, a fresh food compartment, an icemaker in the fresh food compartment includes distinct freezer, fresh food and icemaker evaporators and associated valving operating in conjunction with a common compressor and condenser in order to effectively regulate temperatures in specified zones of the refrigerator throughout various operational modes including at least a freezer cooling mode, a fresh food cooling mode and an ice harvesting mode. The icemaker can be serially linked with the fresh food evaporator during cooling of the fresh food compartment, while being also being selectively isolated for the ice harvesting mode.Type: ApplicationFiled: June 22, 2011Publication date: December 27, 2012Applicant: WHIRLPOOL CORPORATIONInventors: ANDERSON BORTOLETTO, NIHAT CUR, TONY L.

Publication number: 20120324919Abstract: A clear ice making system and method utilizes an ice forming tray pivotally connected to opposing side walls of an icemaker housing. Ice forming fingers of a dedicated evaporator extend into fluid within the ice forming tray, and are cooled by communication with the refrigerant circulating system of the refrigerator. A motor oscillates the ice forming tray about a longitudinal axis at a frequency of about 0.4-0.6 hertz as fluid channels freezes on the ice forming fingers over time, forming clear ice pieces. During an ice dispensing event, the motor pivots the ice making tray about the longitudinal axis such that fluid remaining within the ice making tray drains into a fluid reservoir below. The ice forming fingers are then heated to release the clear ice pieces for transfer from the fresh food compartment to the freezer compartment of the refrigerator.Type: ApplicationFiled: June 22, 2011Publication date: December 27, 2012Applicant: WHIRLPOOL CORPORATIONInventors: ANDERSON BORTOLETTO, KEVIN M.

Publication number: 20120318004Abstract: 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.Type: ApplicationFiled: February 23, 2011Publication date: December 20, 2012Applicant: LG ELECTRONICS INC.Inventors: Bongjin Kim, Seongjae Kim, Moongyo Jung

Patent number: 8256234Abstract: A method for cooling an icemaker is disclosed. The icemaker includes an ice mold body having a channel for transport of coolant and a plurality of ice cavities. The method includes the steps of injecting a coolant into the channel, adding water to the ice cavities, forming ice cubes in the ice cavities, removing coolant from the channel, heating the ice mold body, and ejecting the ice cubes from the ice mold body. The removal step is performed by reversing direction of a coolant pump.Type: GrantFiled: December 12, 2008Date of Patent: September 4, 2012Assignee: General Electric CompanyInventors: Eric K.
