Gas burner with inward facing flame

摘要

A gas burner with inward-facing flames has a base body disposed under a cooktop and a discoid lid disposed onto the base body. The base body has a central chamber connected to a horizontal Venturi tube fed by a gas injector. A peripheral annular chamber and partitions-defining apertures provide communication between the central chamber and the peripheral annular chamber. The lid has a central dish disposed onto the central chamber of the base body, an intermediate toroidal portion disposed onto the partitions of the base body, and a flame ring disposed onto the peripheral annular chamber for propagation of flame inwards.

1. A gas burner with inward-facing flame, the gas burner comprising:
a base body adapted for being disposed under a cooktop, said base body comprising:
a central chamber with a cylindrical or truncated-conical shape, said central chamber adapted for being connected to at least one horizontal Venturi tube fed by at least one gas injector;a peripheral annular chamber; andat least two partitions each defining only one aperture providing communication between said central chamber and said peripheral annular chamber wherein said at least two partitions of said base body have lower ends mutually connected by a bridge in such manner that each of the apertures of the base body has a substantially U-shape defined between an adjacent pair of the partitions and said bridge; and a discoid lid disposed above said base body, said discoid lid comprising:
a central dish disposed onto said central chamber of the said body;an intermediate portion disposed and in contact with said partitions of the base body; anda flame ring disposed onto said peripheral annular chamber of the base body and presenting an inclined surface a plurality of ports is obtained, said plurality of ports communicating with said peripheral annular chamber, said plurality of ports presenting an axis inclined upwards and inwards towards a central vertical axis of the gas burner for propagation of flame inwardly.
