Abstract:
1. A method for controlling the exhaust flow from a cooking chamber of a baking oven, the flow being discharged by a fan, the method comprising the steps: increasing a speed of the fan during a first time interval of a cooking process; measuring a gas concentration of the cooking chamber using a gas sensor during the first time interval during the increasing of the fan speed; determining, during the measuring of the gas concentration, a reference fan speed the reference fan speed being the speed of the fan at which the measured gas concentration changes for the first time during the first time interval from an initial gas concentration to a different gas concentration, the initial gas concentration being the measured gas concentration at a beginning of the first time interval; and setting, using an electrical controller, the speed of the fan as a function of the determined reference fan speed during a second time interval.
