Abstract
The present disclosure is related to a dual ring gas burner wherein the outer ring includes multipoint injection with bottom breathing and the inner ring works with top breathing. Two flame rings are included along with burner ports on the caps. As a result, better heating distribution is achieved along with greater ease in cleaning and combined simmer functions with high ratings by having the outer ring gas flow not interfering with the inner ring.
Claims18
A dual gas burner for a cooking hob having a cooktop panel,
- the dual gas burner comprising:
- an inner burner configured to receive gas from below the cooktop panel and combustible air from above the cooktop panel, the inner burner comprising a central burner cap having a plurality of gas ports configured to pass gas and combustible air, the central burner cap arranged on a crown inlet configured to cooperate with a mixing chamber so as to receive gas from the mixing chamber and combustible air from outside the mixing chamber below the central burner cap, wherein the mixing chamber is arranged below the cooktop panel and the crown inlet is arranged above the cooktop panel so as to define an opening through which the combustible air passes to the crown inlet;
- and
- an outer annular burner configured to receive gas and combustible air from below the cooktop panel.
A dual gas burner for a gas cooking hob having a cooktop surface, the dual gas burner having an inner burner arranged within an outer annular burner, and the dual gas burner comprising:
- a burner body arranged below the cooktop surface, the burner body comprising a mixing chamber arranged to be supplied with gas from a first gas inlet and a plurality of burner body inlets to be supplied with gas from a second gas inlet,
- a crown arranged above the cooktop surface, the crown comprising a crown inlet extending in a downward direction and arranged to cooperate with the mixing chamber so as to receive gas from the mixing chamber, and a plurality of ports extending in a downward direction and arranged to cooperate with the plurality of burner body inlets so as to receive gas from the plurality of burner body inlets;
- a central burner cap having a plurality of gas ports and arranged atop the crown inlet;
- an outer annular burner cap defining an internal opening for accommodating the central burner cap therein and arranged atop and circumferentially about the crown;
- and
- wherein the crown inlet is further arranged to receive combustible air from outside the mixing chamber and above the cooktop surface, and the plurality of ports are arranged to receive combustible air from below the cooktop surface,
- wherein the combustible air for the inner burner is drawn from a location isolated from where the combustible air for the outer annular burner is drawn.
