Food oven

A food oven comprising:

• a cooking compartment configured to house at least one food being cooked and defining a plane for holding the at least one cooking food item;
• a mouth for inserting said food into said compartment;
• and
• a pyrolytic burner heating said compartment allowing the cooking of said food and defining a longitudinal axis suitably normal to said plane;
• wherein said pyrolytic burner comprises
• a fuel combustion chamber;
• an additional chamber surrounding at least in part said combustion chamber;
• at least one connector configured to place said fuel combustion chamber in fluid passage connection with said additional chamber;
• a base structure comprising said compartment, said mouth and a support plane of said food being cooked;
• and in which said plane an opening placed said compartment in fluid passage connection with said pyrolytic burner;
• wherein said fuel combustion chamber has a substantially tumbler shape and thus it comprises a side wall suitably parallel to said longitudinal axis and a bottom suitably normal to said longitudinal axis;
• wherein said additional chamber has a substantially tumbler shape and comprises an additional side wall suitably parallel to said longitudinal axis and an additional bottom suitably normal to said longitudinal axis;
• wherein said connector is configured to place said fuel combustion chamber in fluid passage connection with said additional chamber allowing the gases produced by pyrolysis in said fuel combustion chamber of the fuel, enter said additional chamber and then enter said fuel combustion chamber where the combustion of said gases takes place;
• wherein said connector comprises first holes placed at a distance H1 from said opening and second holes placed at a distance from said opening greater than H1 and distance H2 from the bottom;
• wherein said pyrolytic burner comprises an air supply circulator injecting air into the additional chamber suitably at the additional bottom and then generating a flow of air which is pushed into the additional chamber defining a Venturi effect that supports the passage of said gases;
• through said second holes from said fuel combustion chamber to said additional chamber and then;
• through said first holes from said additional chamber to said fuel combustion chamber where said gases are combusted by the combustion of the fuel, creating a toroidal flame which performs the function of a plug to the entry of air into said fuel combustion chamber and of heating from a part/material below;
• wherein said pyrolysis burner comprises
• an outlet of pyrolysis residue from said fuel combustion chamber and
• a collector of said residue suitably configured to receive said residue by gravity, wherein said outlet comprises
• one or more open sections and
• at least one closure configured to define an open position in which said at least one closure does not overlap with said one or more open sections allowing passage of residue from said fuel combustion chamber to the collector, and a closed position in which said at least one closure overlaps with said one or more open sections preventing passage of residue from said fuel combustion chamber to the collector;
• wherein said collector comprises a drawer for collecting and extracting said residues suitably translatable with respect to the rest of said burner transversely to said longitudinal axis;
• and
• wherein said collector is placed on the opposite side of said fuel combustion chamber with respect to the circulator.
