Document Type and Number:
WIPO Patent Application WO/2014/047706
Kind Code:
A4
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).
