Abstract: The invention relates to a cooking oven with a cavity for placing a dish to be cooked, with a first opening in the wall of the cavity at a first location, wherein the first opening can be opened and closed by means of a first valve, wherein a first conduit is arranged adjacent to the first opening leading to a fan element, and with a second opening in the wall of the cavity at a second location, wherein the second opening is in fluidic connection with a fresh air opening which can be opened and closed by means of a second valve, wherein the fresh air opening is in fluidic connection with the ambient of the cooking oven. The invention further relates to and improved a steam cooking process. Furthermore, the invention relates to a method for operating a cooking oven.

Abstract: A cooking appliance comprises at least one cooking compartment, at least one installation compartment, at least one gas sensor array for detecting the atmosphere within the cooking compartment, the atmosphere within the installation compartment, and/or the atmosphere surrounding the cooking appliance. The gas sensor array(s) have at least two separate, different individual sensors and/or at least one coherent sensor field including at least two different sensor segments. The cooking appliance additionally includes at least one storage unit for storing signals detected by the gas sensor array(s), at least one evaluation unit for processing the detected signals, at least one control unit for controlling cooking or cleaning processes, at least one first feed line for transporting the atmosphere from the cooking appliance to the gas sensor array(s), and at least one valve at the inlet and/or in the area of the first feed line.

Abstract: A method for controlling a delta-T cooking process includes (a) selecting of a set core temperature KTs and a delta-T value for the food to be cooked, (b) introducing the food to be cooked into the cooking space at an initial core temperature KT0; (c) increasing the actual cooking space temperature GTa as a function of the actual core temperature KTa over the course of at least one first time interval in such a way that an essentially constant difference approximately on the order of magnitude of the delta-T value is maintained between GTa and KTa until KTa=KTs+A and thus corresponds to a maximum value GTa-r, where A is a temperature value smaller than delta-T; and finally (d) stepwise and/or continuously decreasing the actual cooking space temperature GTa during a second time interval to a final cooking space temperature of GTe=KTs+B, where B is a temperature value of 0?B<A, in such a way that, when GTa becomes essentially the same as GTe, KTa reaches KTs more-or-less simultaneously.
