20100258104 | COOK STOVE ASSEMBLY - A combustion chamber, having an upper part and a lower part, may include an annular constriction, in combination with the combustion chamber, to aid in directing partially combusted gases such as carbon monoxide away from the periphery of the combustion chamber back toward its center, and into the flame front. The annular constriction may also impede the flow of partially combusted gases located at the periphery, thus increasing the time these gases spend within the combustion chamber and increasing the likelihood that any products of incomplete combustion will undergo combustion. The combustion chamber may further comprise a dual burner cooktop for directing combustion gases and exhaust to multiple cooking vessels. In further embodiments, the combustion chamber may be made of, lined, or clad with a metal alloy comprising iron, chromium, and aluminum. | 10-14-2010 |

Charcoal or other biomass fuel may be added into the lower combustion chamber and may be supported by a grate. Oxygen may be fed into the combustion chamber through a plurality of apertures that may be substantially shielded from direct line of site of the fuel bed. The upper combustion chamber may further include an annular constriction, to aid in constricting the view factor between the cooking vessel and the fuel bed. The constriction may also aid in radiating energy back to the fuel bed. | 05-19-2011 |

20120180775 | IMPINGEMENT OVEN WITH A PLURALITY OF VARIABLE AIRFLOW COOKING ZONES - Conveyor oven that uses three or more cooking zones to provide flexible baking solutions in a commercial kitchen environment. The flexibility of each zone is achieved by providing variable air velocities in the impingement jets in each zone. By increasing or decreasing the air velocity in the zone the operator can control the heat transfer rate to the food product in that zone without having to actually adjust the temperature of the oven. The airflow rate in the zones is controlled via the operator controller. | 07-19-2012 |

20130133637 | SYSTEMS AND METHODS FOR ADJUSTING OVEN COOKING ZONES - A cooking system having adjustable oven cooking zones generally includes a spiral stack disposed within a cooking oven chamber, the spiral stack including a plurality of tiers, and a circulation system for delivering gaseous cooking medium to the spiral stack in the cooking oven chamber. The system further includes a mezzanine assembly including an inner mezzanine and an outer mezzanine, wherein the position of the inner mezzanine is movable relative to the position of the outer mezzanine. Methods for adjusting cooking zones in an oven, and systems and methods for bidirectional flow systems for cooking ovens, are also provided. | 05-30-2013 |
20140026880 | AIR FLOW MANAGEMENT FOR AN OVEN APPLIANCE WITH HIDDEN HEATING SOURCE - An oven appliance with one or more features for managing the flow of heated air within the oven cavity is provided. Such features are provided on a floor or wall that is positioned over one or more heating elements. The features are configured to disrupt the formation and/or flow of a high temperature film so that heated air is more uniformly distributed within the oven cavity in order to promote a more uniform cooking of food items therein. | 01-30-2014 |

20110253123 | FLOW DIRECTING DEVICE FOR A COOKING APPLIANCE - A cooking appliance including an interior, a fan mechanism having at least one fan wheel in the interior, at least one first flow directing member for subdividing the interior into a pressure chamber that houses the fan wheel and a cooking chamber, in which the first flow directing member includes at least one suction port for sucking atmosphere from the cooking chamber into the pressure chamber when the fan wheel is in operation and at least one blow-off port for blowing atmosphere from the pressure chamber into the cooking chamber when the fan wheel is in operation; and at least one second flow directing member that is included with the fan mechanism in the area of the suction port of the first flow directing member in order to improve the flow from the cooking chamber into the pressure chamber by forcing an axial main flow H in the suction zone of the fan mechanism, where the second flow directing member performs a nozzle function, extends from the fan mechanism into the cooking chamber, and overlaps the edge of the suction port of the first flow directing member, and where the first flow directing member extends into the second flow directing member. | 10-20-2011 |
20130112187 | PORTABLE COMBUSTION DEVICE UTILIZING THERMOELECTRICAL GENERATION - This invention provides a portable combustion device that provides a cleaner combustion, reduces the kindling period, and provides a more efficient overall combustion through the use of a fan that directs a predetermined volume of airflow over the combustible fuel—typically wood or similar cellulose-based biological solids. The combustion device has a combustion chamber with a fuel source. A housing encloses the TEG on the side of the device that generates an electrical output based on a temperature differential between opposing TEG sides. A heat-conducting probe is mounted to the TEG and protrudes into the combustion chamber. The opposing TEG side contacts a heat sink that interacts with ambient air. A fan draws heated air away the heat sink, and forces the air onto the combusting fuel through a plurality of peripheral ports that connect with an air space located between inner and outer walls of the combustion chamber. | 05-09-2013 |
20130255655 | OVEN WITH AMBIENT AIR COOLING - An oven is described having an interior space defined by a plurality of side walls, a duct, and a blower. The duct is in fluid communication with a ventilation aperture in at least one of the side walls and a supply of ambient air external to the oven cavity.

The bracket is configured to secure the switches within the airflow pathway to maintain the switches at a temperature below their respective activation temperatures when the fan is operating properly. Additionally, the bracket conducts heat directly from the frame to the switches so that when the fan malfunctions, the reaction time of the switches in reaching their respective activation temperatures is reduced. An appliance incorporating such a fan apparency arrangement is also disclosed. | 11-28-2013 |
