Gas burner secondary air feed

Abstract

The present invention refers to a gas burner secondary air feed, comprising an air inlet ( 2 ) in contact with ambient air; an air exit ( 3 ) near the base of flames 9 of a burner ( 7 ); an elongated duct ( 1 ) connecting said air inlet ( 2 ) to said air exit ( 3 ), said duct being disposed beneath a cooking table ( 8 ) and capable of supplying an air flow from the air inlet ( 2 ) towards said air exit ( 3 ) by convection generated by flames ( 9 ) of the burner ( 7 ). Said duct ( 1 ) comprises a straight section ( 6 ) substantially parallel to the flat portion of said cooling table ( 8 ) and an upward section ( 5 ) directed to flames ( 9 ) of the burner ( 7 ), said straight section ( 6 ) connected to the upward section ( 5 ) by means of an inflection region ( 4 ).

1 . Gas burner secondary air feed, characterized in that it comprises:
 an air inlet ( 2 ) in contact with ambient air;   an air exit ( 3 ) near the base of flames  9  of a burner ( 7 );   an elongated duct ( 1 ) connecting said air inlet ( 2 ) to said air exit ( 3 ), said duct being disposed beneath a cooking table ( 8 ) and capable of supplying an air flow from the air inlet ( 2 ) towards said air exit ( 3 ) by convection generated by flames ( 9 ) of said burner ( 7 ).   
     
     
         2 .
