Abstract
A gas burner (300) with inward-facing flame is disclosed, comprising a base body (2) comprising a chamber (21) connected to a radial venturi pipe (7) fed by a gas injector (6); a mixing body (4) with toroidal base (42) that defines a toroidal mixing chamber (40) communicating with the chamber (21) of the base body; a circular upper cover (5) with internal surface (52) facing towards the axis of the upper cover, wherein a plurality of holes (53) is obtained, in communication with the mixing chamber (40) for inward-facing emission of flames.
Claims18
A gas cooking assembly (100;
- 200) comprising a gas burner and a cooktop (1), the gas burner comprising:
- a base body (2) disposed under the cooktop (1), said base body (2) comprising a chamber (21) connected to at least one horizontal venturi pipe (7) fed by at least one gas injector (6);
- an intermediate cover (3) disposed above said base body, substantially at the same level as the cooktop (1), said intermediate cover (3) being a disc-shaped plate and comprising at least one slot (31) in communication with said chamber (21) of the base body;
- a mixing body (4) disposed above said base body (2) and above the cooktop (1), said mixing body (4) comprising:
- a base (42) with toroidal shape that defines a toroidal mixing chamber (40) communicating with the chamber (21) of the base body;
- and
- at least one hole (43) for secondary air passage;
- and
- a circular upper cover (5) disposed above said mixing body (4), said upper cover (5) comprising:
- at least one hole (50) communicating with said at least one hole (43) of the mixing body for secondary air passage;
- and
- an internal surface (52) facing towards the axis of the upper cover in which a plurality of flame holes (53) is configured in communication with the mixing chamber (40) so as to release flames inwards;
- wherein the base (42) of the mixing body (4) is spaced apart from the base body (2) and cooktop (1) by a gap (8), the cooking assembly thereby being configured to allow a first secondary air flow (F2′) to flow above the cooktop (1) and through said at least one hole (43) of the mixing body and said at least one hole (50) of the upper cover to feed with air the flames outgoing from the flame holes (53) of the upper cover,
- wherein
- said upper cover (5) has an external surface (51) inclined by an angle (α) between 55° and 75° with respect to a plane (P) parallel to the cooktop (1) and an internal surface (52) inclined by an angle (β) between 5° and 25° with respect to said plane (P) parallel to the cooktop (1), thereby being configured to generate a second secondary air flow (F2″) above the cooktop (1) grazing the external surface (51) and the internal surface (52) of the upper cover.

- a base (42) with toroidal shape that defines a toroidal mixing chamber (40) communicating with the chamber (21) of the base body;
- and
- at least one hole (43) for secondary air passage;
- and
- a circular upper cover (5) disposed above said mixing body (4), said upper cover (5) comprising:
- at least one hole (50) communicating with said at least one hole (43) of the mixing body for secondary air passage;
- and
- an internal surface (52) facing towards the axis of the upper cover in which a plurality of flame holes (53) is configured in communication with the mixing chamber (40) so as to release flames inwards;
- wherein the base (42) of the mixing body (4) is spaced apart from the base body (2) by a gap (8), the gas burner thereby being configured to allow a first secondary air flow (F2′) to flow above the base body (2) and through said at least one hole (43) of the mixing body and said at least one hole (50) of the upper cover to feed with air the flames outgoing from the flame holes (53) of the upper cover,
- wherein
- said upper cover (5) has an external surface (51) inclined by an angle (α) between 55° and 75° with respect to a horizontal-plane (P) and an internal surface (52) inclined by an angle (β) between 5° and 25° with respect to said horizontal plane (P), thereby being configured to generate a second secondary air flow (F2″) above the base body (2) grazing the external surface (51) and the internal surface (52) of the upper cover.
