                  | (54) | Household oven interactive control and selection system | 
            
(57) The system provides for oven control allowing the carrying out, both manually and
            by selecting preset recipes, of the different stages involved in cooking. Interactive
            selection allows programming thereof to carry out recipes automatically once the same
            is selected or activating the various types of oven according to the user's selection.
To such end, the system is provided with two functionally linked cards, a MASTER card
            (1) dealing with system control and a SLAVE card (2) basically aimed to try and represent
            the information on a CRT display (28) interacting with the former.
Especially to be noted within the power supply (3) is the presence of a mains fault
            detector circuit (38) and a mains-battery/battery-mains switching circuit (39), so
            that the structure and processes that can be carried out allow oven control and interaction
            with the user through a selection keyboard 912) and the CRT display (28).
