Double burner for gas hot plates with multiple flame crowns

Abstract

The present invention relates to a double burner for gas hot plates with concentric flame crowns, provided with a deflector partition ( 100 ) situated in front of the outlet of each axial Venturi mixing chamber ( 6 a ) designed to deflect the mixture laterally in the two directions and downwards until it passes through an opposite pair of openings ( 101 ) astride each deflector partition ( 100 ), through which the mixture reaches the corridors ( 11 ) that feed the holes ( 103 ) from which the external flames (FE) emanate.

1 . Double burner for gas hot plates with multiple concentric flame crowns, of the type comprising a head (T) with multiple concentric flame crowns and a circular tub-shaped body ( 1 ), which houses a cross-piece ( 2 ) with nozzles on top and two different and non-communicating gas inlet conduits ( 3  and  4 ) on the bottom, each of the inlet conduits being designed to selectively and respectively feed the nozzle ( 5 ) associated with the central flame crown (FC) and the group of nozzles ( 6 ) associated with the external flame crowns (FE); in which the group of nozzles ( 6 ) is formed of at least three regularly spaced nozzles ( 6 ) that feed corresponding axial Venturi mixing chambers ( 6   a ) with inclined axis, and the nozzle ( 5 ) feeds a corresponding radial Venturi mixing chamber ( 5   a ) with vertical axis; burner characterised in that said burner comprises a deflector partition ( 100 ) situated in front of the outlet of each axial Venturi mixing chamber ( 6   a ), which forces the mixture to deflect laterally in the two directions and downwards until the mixture passes through an opposite pair of openings ( 101 ) astride each deflector partition ( 100 ), through which the said mixture reaches the corridors ( 11 ) that feed the holes ( 103 ) from which the external flames (FE) emanate. 
   
   
       2 . Burner as claimed in  claim 1 , characterised in that the head (T) is formed of a lower dish ( 7 ) and an upper dish ( 8 ) that are shaped in such a way as to be perfectly matched and in that the said deflector partitions ( 100 ) are obtained in one moulded piece with the upper dish ( 8 ) of the head (T) provided with the said openings ( 101 ). 
   
   
       3 . Burner as claimed in  claim 2 , characterised in that the said circular corridors ( 11 ) are obtained on the upper side of the dish ( 8 ) and partially house an annular cap ( 102 ) provided with a series of holes ( 103 ) from which the external flames (FE) emanate.
