Abstract

The present invention relates to a gas cooking household appliance provided with a gas fitting (AG) and one or more gas burners (B1,B2,B3,B4); it comprises a general automatic valve (VG) having an inlet associated with said fitting (AG), one or more individual automatic valves (V1,V2,V3,V4) having outlets respectively associated with said one or more burners (B1,B2,B3,B4), and a pipe (TU) which connects the outlet of the general valve (VG) to the inlets of said one or more individual valves (V1,V2,V3,V4); it also comprises an electronic safety system (EL) adapted to detect any malfunctions and/or failures which might cause undesired gas flow at least through said general valve (VG).
