Abstract

A control method for operating a cooking oven in a deep-frying program which is configured for a predetermined set temperature is disclosed, wherein the cooking oven has an oven cavity, a tray arranged within the oven cavity, a bottom heating element for heating the bottom of the cavity, a fan located at the rear wall of the cavity, and a ring heating element surrounding the fan. The method comprises the following stages: (a) a heat-up phase in which the ring heating element is continuously operated and the bottom heating element is intermittently operated, the heat-up phase being conducted until reaching a temperature of the oven cavity which corresponds to the set temperature plus a predetermined first hysteresis; (b) a subsequent holding phase in which the bottom heating element and the ring heating element are non-operative; and (c) a frying phase conducted upon reaching a temperature within the oven cavity which corresponds to the set temperature minus a predetermined second hysteresis, the frying phase comprising continuously or intermittently operating the ring heating element, and intermittently operating the bottom heating element so as to raise the temperature within the …
