Gas flow directing device for burners of cooking appliances

Abstract

The present invention refers to a gas flow directing device ( 1 ) for burners ( 2 ) of cooking appliances, comprising innovative technical and functional features capable of better using gases from combustion process. However, it is mainly directed to maximize the efficiency of heat exchange of burners with cooking utensils. More particularly, said gas flow directing device ( 1 ) of the present invention comprises a base ( 3 ) provided with opening ( 4 ) for fitting a burner ( 2 ), wherein said base ( 3 ) is arranged such that it can be freely rotated around the burner ( 2 ) and comprises at least a pathway ( 5 ) configured from the arrangement of at least one outwardly projected distribution wall ( 6 ) containing at least an opening ( 7 ).

1 . A cooking appliance burner including a gas flow directing device, the gas flow directing device comprising:
 a base including an opening to fit the burner,   wherein the base is adapted to freely rotate around the burner, and the base comprising at least a pathway configured from an arrangement of at least one of an upwardly projected distribution wall having at least one opening, wherein the base is coupled with an electric and/or electronic mechanism.   
     
     
         2 . The cooking appliance burner including the gas flow directing device according to  claim 1 , wherein the burner is coupled with the base by a fitting mechanism, such that the base is adapted to freely rotate around the burner. 
     
     
         3 . The cooking appliance burner including the gas flow directing device according to  claim 1 , wherein the electric and/or electronic mechanism comprises computational capacity to control the rotation of the base. 
     
     
         4 . The cooking appliance burner including the gas flow directing device according to  claim 1 , wherein the at least one of the upwardly projected distribution wall is arranged on an inner edge of the base close to the opening, the wall having a helical form, such that surfaces of the wall form at least one of an arc of a circle, or flat surfaces disposed side-by-side.  
     
     
         5 . The cooking appliance burner including the gas flow directing device according to  claim 1 , wherein the at least one distribution wall is continuous. 
     
     
         6 . The cooking appliance burner including the gas flow directing device according to  claim 1 , further comprising distribution walls having openings diametrically opposed to each other.
