Publication number: 20120103978Abstract: Microwave heating apparatus for chemical-physical processes comprising a microwave source, operatively connected to an end of an antenna at a connector. The antenna is put in a reaction container where it irradiates with microwaves a reacting material. The antenna is coated with a sheath that avoids a direct contact with the reacting material, or is put into in a housing executed in the container. The housing, made of a material transparent to microwaves, can cross the reaction container for a part thereof, or for all its width. The arrangement of the antenna in the reacting material provides a quick and effective heating. Furthermore, it is possible to increase considerably the selectivity, the control and the efficiency of a chemical-physical processes to which the heating technique above described is applied. This allows also to provide a considerable energy saving with respect to apparatus of prior art.Type: ApplicationFiled: November 9, 2011Publication date: May 3, 2012Applicant: CNR CONSIGLIO NAZIONALE DELLE RICERCHEInventor: Iginio LONGO

Patent number: 8119955Abstract: The present invention relates to a device for preventing microwave leakage for a microwave oven. The present invention comprises a cavity assembly formed with an opening portion through which heating energy generated in an energy generating means is supplied into a cooking chamber provided within the cavity assembly; a cover provided on a side of the cavity assembly to cover the opening portion; and a choke member provided between the cavity assembly and the cover to prevent microwave supplied into the cooking chamber from leaking through a gap between the cavity assembly and the cover. According to the present invention, there is an advantage in that microwave is effectively prevented from leaking through a gap, which is formed when installing a heating means for providing a heating source in addition to the microwave.Type: GrantFiled: July 12, 2006Date of Patent: February 21, 2012Assignee: LG Electronics Inc.Inventor: Kwang-Yong Park

Publication number: 20120034350Abstract: A roasting oven includes an enclosure coupled to a source of microwave RF energy, an operable door for sealing the enclosure for RF, the operable door having a viewing aperture which prevents the escape of RF from inside the chamber. A rotating support has an axis which is perpendicular to the viewing aperture such that the progress of roasting may be viewed through the viewing aperture and into a food container placed in the rotating support. The applied power of the microwave RF source and the rotational velocity of the rotating support are selected to provide uniform or wide spectrum roasting of the food item. A roasting profile may include a roasting interval during which the microwave RF source and rotating support are both energized, and subsequently a cool-down interval where the microwave RF source is disabled and the rotating support continues to rotate.Type: ApplicationFiled: July 23, 2011Publication date: February 9, 2012Applicant: COFFEE TECHNOLOGY INTERNATIONAL, INCORPORATEDInventors: Robert G.

Publication number: 20120024844Abstract: A cooking appliance such as a microwave oven is provided with a sacrificial region for repairing damage caused by arcing and related failure modes. The sacrificial region incorporates a component that, when damaged, is removable from the cooking appliance for replacement by another component of similar construction. In one implementation, a sacrificial component is utilized in a microwave oven with a heated cavity subject to microwave radiation from a magnetron. The sacrificial component in this example includes an aperture that communicates with an opening in the cavity, and through which the radiation impinges into the heated cavity.Type: ApplicationFiled: August 2, 2010Publication date: February 2, 2012Inventors: Patrick Galbreath, Mark Heimerdinger

Publication number: 20110297673Abstract: The present invention relates to a wave choke system for a door of a microwave oven. The wave choke system comprises at least one wave trap (10) formed as an elongated channel and bordered by four channel walls (22, 24, 32, 34) made of one or more conductive materials and by at least one gap (28). The wave trap (10) is provided for extending at least partially along a door frame and/or along a cavity frame (12). The wave trap (10) comprises at least two adjoining wave choke recesses (14, 16) for a ?/4 transformation parallel to each other and parallel to the wave trap (10). Two neighbouring wave choke recesses (14, 16) are separated by an elongated wave barrier (18) made of one or more conductive materials. The height of the wave barrier (18) is lower than the height of the wave trap (10).Type: ApplicationFiled: March 26, 2010Publication date: December 8, 2011Applicant: ELECTROLUX HOME PRODUCTS CORPORATION N.V.Inventors: Abdel-Ilah Zbat, Arnd Hofmann
