Patent number: 9581363Abstract: An ice maker having an ice tray horizontally suspended within a housing and a drive body rotatably coupled to a transverse axis of the ice tray and configured to oscillate the ice tray about the transverse axis. The cold side of a thermoelectric device is thermally coupled with a bottom surface of the ice tray, and a hot side opposes the cold side. A barrier extends around the periphery of the ice tray within the housing, and separates the housing into a first chamber and a second air chamber. A heat sink is thermally coupled with the hot side of the thermoelectric device and extends into the second air chamber. An intake duct member is coupled with the housing proximate the second air chamber, and is configured to dispense a cold air flow over the heat sink. The barrier restricts the cold air flow from entering the first chamber.Type: GrantFiled: December 28, 2015Date of Patent: February 28, 2017Assignee: Whirlpool CorporationInventors: Patrick J.

Patent number: 9482455Abstract: A system comprising a gear having at least one slot, wherein the gear is connected to an icetray and a motor so that when the motor rotates the gear, the icetray twists, and an optical sensor that detects when the gear has rotated the slot over the optical sensor. The icetray twists while the gear is rotated in a first direction away from a home position to a reverse twist position. The rotation of gear then reverses to twist the icetray to a harvest position in a second direction that is opposite of the first direction until ice in the icetray is dislodged.Type: GrantFiled: April 9, 2015Date of Patent: November 1, 2016Assignee: ENVOLVE ENGINEERING, LLCInventors: Gregory Gene Hortin, Kyle Carter Edmondson, Patrick J.

Patent number: 8844309Abstract: A refrigerator includes a fast ice making device for quickly producing ice cubes. The fast ice making device includes a mold body having a plurality of ice forming cavities adapted to hold fluid. In an ice making cycle, a vacuum system evacuates air from the cavities, thereby depressurizing the cavities. Then, a liquid delivery system delivers liquid to the depressurized cavities, whereby an initial portion of the liquid bubbles up within the respective cavities. Overall, a cooler fluid is established at the beginning of an ice making cycle, thus accelerating the rate at which ice cubes are formed within the fast ice making device. Once ice cubes have been formed within the cavities, a heat transfer system is utilized to heat the cavities, thereby slightly melting the ice cubes and aiding in the expulsion of ice cubes from the cavities.Type: GrantFiled: March 15, 2010Date of Patent: September 30, 2014Assignee: Whirlpool CorporationInventors: Alexandre D. Grosse, Adriana S. Guillen

Patent number: 8844314Abstract: A clear ice making system and method utilizes an ice tray including a plurality of ice forming cavities extending into a fluid supply cavity. Fluid supplied to the fluid supply cavity flows into each of the plurality of ice forming cavities and out through respective fluid outlets located in a bottom portion of the ice forming cavities to a fluid outlet chamber below. Cooled ice forming members extend into respective ice forming cavities. Fluid is continuously cycled through the ice forming cavities and around the ice forming members during an ice making event such that clear ice pieces gradually form on each of the ice forming members. During an ice harvest event, ice forming members are heated to release formed ice pieces, and the ice pieces are transferred from a fresh food compartment of a refrigerator to an ice storage bucket located in a freezer compartment of the refrigerator.Type: GrantFiled: June 22, 2011Date of Patent: September 30, 2014Assignee: Whirlpool CorporationInventors: Anderson Bortoletto, Rogerio Soares Brisola, Douglas D.
