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.

A household stove burner with upper intake air and super-high power includes cup body, distributor base, central distributor, outer ring distributor, ignition needle, induction needle, air intake base, central air intake tube, left air intake tube, right air intake tube, gap between central air intake tube, light tube portion of central tube. The gap between left air intake tube and light tube portion of left outer ring tube, gap is between right tube and light tube portion of right outer ring air intake tube, a lower end of air intake cavity of distributor base is docked with outer ring pre-mixing cavity, outer interface of outer ring distributor is inserted into outer ring fuel gas tank, inner ring wall plate of outer ring fuel gas tank inserted into outer ring distributor. Outer ring flame stabilizing slot to prevent generation of outer ring firm flame to improve dissipation performance.

A burner comprising a base cup, an annular flame splitter, and a flame cover. The base cup comprises an air inlet channel and two nozzles in communication with the air inlet channel and arranged upwards. The annular flame splitter arranged on the base cup comprises two Venturi tubes respectively arranged opposite the two nozzles. The annular flame splitter is separated from the base cup to form a gap, thus allowing primary air to enter the two Venturi tubes from the gap to be mixed with a fuel gas sprayed into the two Venturi tubes by the two nozzles to form a gaseous mixture. Groove openings are formed on the top of the annular flame splitter in communication with the mixing cavity. The flame cover covers the mixing cavity and limits the groove openings to define the outlet for the gaseous mixture, thus forming a flame ring.

A burner cover for a gas burner includes a disk-shaped base segment, and an annular gas distribution segment which is connected to the base segment. The gas distribution segment has first gas distribution channels, which extend radially from an inner surface of the gas distribution segment toward an outer edge of the base segment. Each first gas distribution channel extends through the gas distribution segment and has a T-shaped cross-sectional geometry, which is open in a direction pointing away from the base segment.

A gas burner for cooking appliances includes a cup-shaped lower support structure to be applied in a position corresponding with an opening made in the sheet metal of a cooking hob, an injector of substantially horizontal axis, applied to a lateral wall of a first cavity provided in the support structure, a substantially horizontal venturi conduit coaxial with the injector and opening at its downstream end into a second cavity provided in the support structure, open upwards, and communicating fluidly with a distribution chamber for the combustion mixture to generate a flame ring, wherein the venturi conduit includes a tubular element separate from the support structure, housed to undergo free axial movement within a corresponding seat provided in the support structure and lockable in the desired axial position by a locking member accessible from above the support structure through the opening provided in the sheet metal of the cooking hob.

A household stove burner with upper intake air and super-high power includes cup body, distributor base, central distributor, outer ring distributor, ignition needle, induction needle, air intake base, central air intake tube, left air intake tube, right air intake tube, gap between central air intake tube, light tube portion of central tube. The gap between left air intake tube and light tube portion of left outer ring tube, gap is between right tube and light tube portion of right outer ring air intake tube, a lower end of air intake cavity of distributor base is docked with outer ring pre-mixing cavity, outer interface of outer ring distributor is inserted into outer ring fuel gas tank, inner ring wall plate of outer ring fuel gas tank inserted into outer ring distributor. Outer ring flame stabilizing slot to prevent generation of outer ring firm flame to improve dissipation performance.

A gas burner for a household cooking appliance includes a first mixture-distribution chamber having a plurality of mixture-outlet openings, and a second mixture-distribution chamber separate from the first mixture-distribution chamber. The second mixture-distribution chamber is fluidically connected to the mixture-outlet openings of the first mixture-distribution chamber such that, when the gas burner is in operation, a combustion-gas/primary-air mixture is conducted out from the first mixture-distribution chamber and a combustion-gas/primary-air mixture is conducted out from the second mixture-distribution chamber via the mixture-outlet openings for flame formation.

Provided is a burner including a burner head configured to receive a mixed gas; and a burner cap configured to cover the burner head, wherein the burner head includes an outer wall having a plurality of first flame holes at which flame are generated, an inner wall spaced from the outer wall and having a plurality of second flame holes at which flame are generated, and a mixed gas chamber formed between the outer wall and the inner wall, and a staying guide provided at an inner circumferential surface of the inner wall and configured to allow the mixed gas flowing from the mixed gas chamber to be stayed thereon.

The present disclosure discloses an energy-efficient upside-entrainment burning system, which includes: a gas distributor component, an ejection pipe component, an outer-ring burner cap, an inner-ring burner cap, a plurality of gas nozzles. The ejection pipe component is arranged below gas distributor component, is provided with two ejection channels in a centrosymmetric structure corresponding to the outer-ring gas mixing chamber, also provided with two ejection channels in a centrosymmetric structure corresponding to inner-ring gas mixing chamber. Each ejection channel is arranged in a Venturi pipe structure. In a gas flowing direction, an ejection pipe inlet, a contraction section, a throat section, an expansion section, an ejection pipe outlet are arranged in sequence. An ejection capability is taken as a target parameter, each ejection capability parameter is of adjustment simulation to obtain optimum design of each structural detail of burner to form the energy-efficient upside-entrainment burning system with an optimum ejection capability.

A gas burner assembly for a cooking hob, in particular for a domestic cooking hob, includes at least two burner bases arranged side-by-side-and a burner crown element arranged or arrangeable above the burner bases. At least one burner cap is arranged or arrangeable above the burner crown element. The burner bases are adjustable separately. The burner crown element includes a bottom plate subdivided into at least two portions arranged side-by-side. Each portion of the bottom plate is arranged or arrangeable above one of the burner bases. The burner crown element includes at least two side walls. Each side wall encloses one of the portions of the bottom plate. The burner crown element includes flame ports formed in the side walls. The flame ports are arranged in those sections of the side walls arranged opposite to the adjacent portion or portions of the bottom plate.
