| 20150292750 | Electric Cooking Apparatus Having an Air Flow - Provided is an electric apparatus for cooking and/or reheating food, including: a housing having a cooking tray arranged such as to receive the food to be cooked and/or reheated, a circuit for heating by ventilation, including a ventilation sleeve having an outlet arranged such as to direct an air flow onto the food to be cooked and/or reheated, and the heating means arranged in the ventilation sleeve such as to heat the air flow by radiation and by convection, wherein at least a portion of the heating means is arranged relative to the outlet of the ventilation sleeve, whereby the heat radiation produced by said portion of the heating means directly heats the food to be cooked and/or reheated. | 10-15-2015 |
| 20150330642 | CONVECTION BASED COOKING APPARATUS HAVING ENHANCED HEAT RETENTION - An invention is afforded for a convection based cooking apparatus having enhanced heat retention. The convention based cooking apparatus includes a cooking chamber configured to holding food to be processed. An air inlet is situated in fluid communication with the cooking chamber for receiving air into the cooking chamber, and an air outlet is provided in fluid communication with the cooking chamber for venting the cooking chamber. In addition, a heating source is included that is configured to switch between an ON state and an OFF state, whereby a temperature of air located within the cooking chamber is regulated. Further, a drafting means is provided that is configured to circulate air present within the cooking chamber. In communication with the air outlet is a vent prevention apparatus. The vent prevention apparatus allows air to escape the cooking chamber via the air outlet when the heating source is in the ON state, and prevents air from escaping the cooking chamber via the air outlet when the heating source is in the OFF state. | 11-19-2015 |
| 20160025355 | OVEN APPLIANCE AND METHOD FOR OPERATING OVEN APPLIANCE - Oven appliances and methods for operating oven appliances are provided. An oven appliance includes a cabinet defining a cooking chamber and a heating chamber, the cooking chamber including a top wall and a bottom wall spaced apart along a vertical direction, the heating chamber disposed below the cooking chamber and including the bottom wall and a base wall spaced apart along the vertical direction. The oven appliance further includes an inlet aperture defined in the bottom wall, and a plurality of outlet apertures defined in the bottom wall, each of the plurality of outlet apertures disposed proximate a periphery of the bottom wall relative to the inlet aperture. The oven appliance further includes a heating element disposed within the heating chamber and configured to heat the cooking chamber, and a fan operable to flow air along an air flow path between the cooking chamber and the heating chamber. | 01-28-2016 |
| 20160061490 | Cooking Appliance - Provided is a cooking appliance having an improved structure in which superheated steam is capable of being used during a cooking operation. The cooking appliance supplies superheated steam while food is cooked, and includes: a main body, a front of which is opened and in which a cooking compartment is disposed; a heating chamber disposed in the main body to be in communication with the cooking compartment; a steam generator disposed to generate steam sprayed into the heating chamber; and a convection heater disposed in the heating chamber to heat the heating chamber and the cooking compartment. The convection heater heats steam discharged from the steam generator, and the steam discharged from the steam generator, in a superheated steam state, is sprayed into the heating chamber and supplied into the cooking compartment. | 03-03-2016 |
| 20160146473 | HEATING DEVICE WITH CONDENSING COUNTER-FLOW HEAT EXCHANGER - A heating device includes a heating device chamber, a heating element for heating air in the heating device chamber, and a condensing counter-flow heat exchanger including a first flow path that receives outgoing air from the heating device chamber and a second flow path for providing incoming air to the heating device chamber. The first flow path and the second flow path are configured in a counter-flow heat exchange relationship such that the outgoing air flows in a direction opposite the incoming air and the latent heat of evaporated water in the outgoing air is transferred to the incoming air thereby condensing liquid water from the outgoing air. | 05-26-2016 |
