Abstract
Cooking apparatus (1) including a cooking chamber (2) comprising an electric resistance browning device (3) for the foodstuff disposed in the chamber (2) and a device (4) for the generation of microwave energy disposed outside the cooking chamber (2) and adapted to supply the chamber with microwave energy. An electric supply circuit supplies the browning device (3) and/or the device (4) for generation of microwave energy. A selector permits triggering a heating sequence to be performed on a foodstuff. This sequence causing the browning device and/or the device for the generation of microwave energy to kick in. The selector recognizes the nature and weight of the foodstuff, and a control actuates the electrical supply circuit as a function of information from the selector. The control comprises a storage memory receiving the information from the selector, and a microprocessor supplying signals applied to the supply circuit as a function of the information contained in the storage memory. The storage memory contains values i corresponding to heating sequences; code numerals .alpha..sub.i corresponding each to one particular type of foodstuff for a predetermined value i, and delimited, for each value i, between a lower value m.sub.i and an upper value M.sub.i ; and tables of values corresponding to coefficients of slopes km.sub.i and kM.sub.i of curves for optimizing heating of a foodstuff which are predetermined as a function of the values i, and which represent the heating time of the cooking apparatus as a function of the weight of the foodstuff, the coefficients corresponding respectively to maximum and minimum values of the slope of the curves.
