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).

Abstract: The present invention relates to a grid used in stoves which comprises innovative technical and functional characteristics capable of increasing the thermal efficiency of the burners. More preferably, the grid according to the present invention comprises an upper crown (1) provided with a series of fins (2) arranged around the burner (3), these fins (2) form passage and distribution channels (4) of hot gases, and extend to the underside of crown (1), within an air and/or fuel passage chamber (5) in which it is preheated before the combustion itself.
