Claim:
Hood ( 2 ) for extracting and treating cooking gases, in particular associated to a respective cooking cavity ( 8 ) of an oven ( 1 ) as used to cook food in professional kitchen applications, comprising: a catalytic converter ( 12 ), an extracting fan ( 13 ) adapted to extract gases, fumes and vapours from the cooking cavity ( 8 ) of said oven, a first intake aperture ( 4 ) adapted to enable said gases to flow from the interior of the cooking cavity ( 8 ) of said oven into said extractor hood, a third aperture ( 9 ) adapted to enable said gases to be exhausted from the interior of said extractor hood into the outside ambient, a channel ( 10 ), including also successive separate sections, defining a flow path which connects said intake aperture with said exhaust aperture, and within which there are arranged said catalytic converter ( 12 ) and said fan ( 13 ), a first condenser ( 11 ) adapted to condense the water vapour and condensable fats contained in the gas flowing through said channel, said condenser being traversed by the flow of gas that moves through said channel, and a secondary fan ( 33 ) that, via a secondary duct ( 34 ) and a respective outflow port ( 35 ), conveys a stream of air taken in from outside into said cooking cavity ( 8 ), so as to increase the pressure within said cooking cavity wherein said flow path is arranged in such a way that said gases, fumes, and vapours, from inside said cooking cavity ( 8 ), after traversing said first condenser ( 11 ) and said catalytic converter ( 12 ), come into contact with at least a wall of said first condenser ( 11 ) before exiting to the atmosphere.
