Abstract
A gas burner assembly includes a burner body that defines a plurality of inner flame ports at an inner sidewall of the burner body. Each inner flame port of the plurality of inner flame ports is positioned and oriented for directing a flow of fuel inwardly along a radial direction and at a swirl angle relative to the radial direction. The burner body further defines a stability chamber having a simmer flame outlet positioned at the inner sidewall of the burner body between a pair of the plurality of inner flame ports. The simmer flame outlet of the stability chamber is positioned closer to one of the pair of the plurality of inner flame ports than the other of the pair of the plurality of inner flame ports. A related cooktop appliance is also provided.
Claims14
A gas burner assembly, comprising:
- a burner body having an inner sidewall, the burner body defining a plurality of inner flame ports at the inner sidewall of the burner body, each inner flame port of the plurality of inner flame ports positioned and oriented for directing a flow of fuel inwardly and at a swirl angle relative to a radial direction,
- wherein the burner body further defines a stability chamber having a simmer flame outlet positioned at the inner sidewall of the burner body between an adjacent pair of the plurality of inner flame ports, the adjacent pair of the plurality of inner flame ports positioned adjacent the simmer flame outlet of the stability chamber, the simmer flame outlet of the stability chamber positioned closer to one of the adjacent pair of the plurality of inner flame ports than the other of the adjacent pair of the plurality of inner flame ports, the stability chamber at least partially defined by an end wall positioned within the burner body, the end wall positioned opposite the simmer flame outlet about the stability chamber along the radial direction,
- wherein the burner body defines a fuel chamber within the burner body, the plurality of inner flame ports being contiguous with the fuel chamber, the stability chamber extending between a top portion and a bottom portion along an axial direction, the stability chamber having a plurality of inlet ports positioned at the top portion of the stability chamber, the plurality of inlet ports contiguous, with the fuel chamber,
- wherein a top wall of the burner body at the stability chamber slopes downwardly along the radial direction between the plurality of inlet ports and the simmer flame outlet of the stability chamber, and
- wherein the top wall of the burner body at the stability chamber slopes downwardly along the radial direction such that fuel exiting the stability chamber at the simmer flame outlet of the stability chamber has a downward velocity component during operation of the gas burner assembly.

A cooktop appliance, comprising:
- a top panel;
- and
- a gas burner assembly positioned on the top panel, the gas burner assembly comprising a burner body having an inner sidewall and an outer sidewall, the outer sidewall of the burner body extending around the inner sidewall of the burner body along a circumferential direction, the burner body defining a plurality of inner flame ports at the inner sidewall of the burner body, each inner flame port of the plurality of inner flame ports positioned and oriented for directing a flow of fuel inwardly along a radial direction and at a swirl angle relative to the radial direction,
- wherein the burner body further defines a stability chamber having a simmer flame outlet positioned at the inner sidewall of the burner body between an adjacent pair of the plurality of inner flame ports along a circumferential direction, the adjacent pair of the plurality of inner flame ports positioned adjacent the simmer flame outlet of the stability chamber, the simmer flame outlet of the stability chamber positioned closer to one of the adjacent pair of the plurality of inner flame ports than the other of the adjacent pair of the plurality of inner flame ports along the circumferential direction, the stability chamber formed within burner body such that the stability chamber is spaced from the outer sidewall of the burner body along the radial direction,
- wherein the burner body defines a fuel chamber within the burner body, the plurality of inner flame ports being contiguous with the fuel chamber, the stability chamber extending between a top portion and a bottom portion along an axial direction, the stability chamber having a plurality of inlet ports positioned at the top portion of the stability chamber, the plurality of inlet ports contiguous with the fuel chamber,
- wherein a top wall of the burner body at the stability chamber slopes downwardly along the radial direction between the plurality of inlet ports and the simmer flame outlet of the stability chamber, and
- wherein the top wall of the burner body at the stability chamber slopes downwardly along the radial direction such that fuel exiting the stability chamber at the simmer flame outlet of the stability chamber has a downward velocity component during operation of the gas burner assembly.
