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 refers to a combustion system applied in cooking equipments, which comprises technical features capable of enhancing heat exchange efficiency and capacity of cooking equipments through a turbulent combustion regime process. Preferably, the combustion system in accordance with the present invention comprises a fuel feed duct (1) connected to a cooking equipment burner (2) by means of an intermittent mechanism (3) for the purpose of releasing and blocking the fuel flow coming from said feed duct (1) such that an ignition element (4) causes a fuel turbulent combustion in said burner (2).

Abstract: The present invention refers to a burner for cooking equipments which comprises a configuration whose purpose is to ensure the integrity of the flames of the main openings by maintaining the pressure originated in the burner. Particularly, the present invention refers to a burner which comprises a base (1) containing a cavity (2), in which a sustaining element (3) that supports a cover (4) is placed; wherein, between said sustaining element (3) and said cover (4), it is formed a channel (5), which, at least partially, encircles the cited cavity (2) to form at least one pilot flame at the end (6) of said channel (5) that is provided in the periphery of the edge of the cavity (2).

Abstract: The present invention generally refers to a flame gas burner diffuser to be used in stove-type cooking equipments, more preferably in household stoves, comprising technical and functional features capable of improving the efficiency of exchanging heat with the bottom of cooking utensils. More particularly, said diffuser, according to the present invention, comprises a cup (1) provided with a surface (4) comprising an opening (2) at which a cooking equipment is accommodated, wherein over said surface (4) there is a series of barriers (3) duly arranged and positioned so as to form passage pathways and/or extended channels for allowing the hot gas flow generated by the burner flame to pass.

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.

Abstract: The present invention relates to a burner assembly for cooking equipments that has been designed to provide significant improvement in thermal efficiency of the burner and making easier the cleaning process by the user. The burner assembly comprises a base (2) upon which a spreading cover (3) rests, and wherein the coupling of the spreading cover (3) on the base (2) originates one internal chamber of expansion (4) of air-fuel mixture which is released through porticos existing under the perimeter edge of the spreading cover (3), and wherein the base (2) comprises in its internal region at least one feeding orifice (22); the spreading cover (3) comprises at least one perimeter ring (31) cooperating with the base (2) and at least one disc (32) cooperating with the perimeter ring (31) and the burner assembly (1) comprises at least one internal chamber of mixture (4) cooperating with the porticos of the spreading cover (3).

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).
