Publication number: 20130199214Abstract: An insulated icemaking compartment is provided in the fresh food compartment of a bottom mount refrigerator. The icemaking compartment may be integrally formed with the liner of the fresh food compartment, or alternatively, may be modular for installation anywhere in the fresh food compartment. A removable bin assembly with a front cover normally seals the icemaking compartment to maintain the temperature in the compartment. A cold air duct formed in the rear wall of the refrigerator supplies cold air from the freezer compartment to the icemaking compartment. A return air duct directs a portion of the air from the icemaking compartment back to the freezer compartment. An air vent in the icemaking compartment directs another portion of air into the fresh food compartment. A control system provides for controlling refrigerator functions in a manner that promotes energy efficiency.Type: ApplicationFiled: March 15, 2013Publication date: August 8, 2013Inventors: Tim L.

Publication number: 20130192279Abstract: A refrigeration appliance includes a fresh food compartment, a freezer compartment, and an ice maker within the fresh food compartment for freezing water into ice pieces. In one example, a rotatable auger drives the ice pieces out of a removable ice bin via a driving force applied in a first direction. A latch is configured to apply a resisting force to the ice bin along a second direction. In another example, an air mover is disposed within the ice maker for delivering cooled air from an ice maker evaporator to a region adjacent to the ice bin. At least one air channel is formed into an inside surface of the ice maker chamber. In another example, a method of making ice in the refrigeration appliance is provided. The method includes the steps of operating the air mover and a defrost heating of the ice maker evaporator.Type: ApplicationFiled: January 31, 2013Publication date: August 1, 2013Applicant: ELECTROLUX HOME PRODUCTS, INC.Inventor: Electrolux Home Products, Inc.

Publication number: 20130186113Abstract: A mold defines a first volume for an ice cube, the mold comprising a bottom face having an inner perimeter and side faces. Each side face has an inner perimeter, top edge, and bottom edge. The top edge of each side face may be longer than the bottom edge. Each side face may extend inward from the top edge to the bottom edge. The mold may comprise a three-dimensional shape within the first volume, the three-dimensional shape comprising a second volume. The second volume may be defined by a top outer perimeter, a bottom outer perimeter, and at least a bulge of the three-dimensional shape. The bulge may extend upwardly and taper between the bottom outer perimeter and the top outer perimeter. The mold may further define a third volume between the first and second volumes, with the mold configured to receive water within the third volume.Type: ApplicationFiled: September 14, 2012Publication date: July 25, 2013Applicant: PEPSICO, INC.Inventors: Terry Tae-Il CHUNG, Andrey Balanev, Sergey Markosov, George Martsinovsky, Vladimir Vasiliev, Mikhail Verbitsky

Publication number: 20130180268Abstract: An ice making machine using hydrocarbon (HC), and particularly propane, as the refrigerant is disclosed. The ice making machine has components which have been modified in size, type and operation to accommodate the use of HCs, and particularly propane, in the ice making machine refrigerant system. Also disclosed is a low volume condenser especially designed for HCs, and in particular propane, to minimize the volume of flammable/explosive HC in the ice making machine refrigerant system.Type: ApplicationFiled: January 11, 2013Publication date: July 18, 2013Applicant: Manitowoc Foodservice Companies, LLCInventor: Charles E. Schlosser
