A domestic cooking stove comprises a frame that mounts a primary tube, one or more of nozzles for fuel injection, knobs for controlling the fuel injection, mixing tubes for modulating pressure gradient, burner tops for combustion of the air fuel mixture, and pan supports to support the vessel, heat reflectors to reflect heat, and legs to support the frame. Each heat reflector is positioned above burner top to provide secondary air entrainment for combustion by reducing a gap between an inner circumference of heat reflector and an outer circumference of the burner top to minimize heat losses. The heat reflector has a curved orientation to reduce heat transfer in a downward direction and generates eddies that increases heat transfer towards vessel bottom. The legs are positioned below the frame and has a predetermined height to maintain a gap between table top and the frame bottom surface for entrainment of air.

Gas outlet openings are provided at the support structure and have a fluid connection to the chamber. The chamber has a circumferential geometry when looking from above.

A burner assembly includes a base body. A cap is positioned on the base body such that the base body and the cap collectively define a plurality of flame ports. A pilot insert is mounted to the base body. The pilot insert and the base body collectively defining a pilot port. An igniter is configured to generate an ignition spark. An upper spark target is positioned proximate the plurality of flame ports, and a lower spark target is positioned proximate the pilot port. An electrode of the igniter is positionable proximate either the upper spark target or the lower spark target.

A gas burner includes a burner body that defines a plurality of forced induction flame ports. An air outlet orifice is mounted to an injet body at an outlet of an air passage such that the air outlet orifice is oriented for directing a flow of air towards the plurality of forced induction flame ports. A gas outlet orifice is mounted to the injet body at an outlet of a gas passage such that the gas outlet orifice is oriented for directing a flow of gaseous fuel towards the plurality of forced induction flame ports. A pneumatically actuated gas valve is positioned within the injet body. The pneumatically actuated gas valve is configured to adjust from a closed configuration to an open configuration in response to the flow of air through the air passage.

A gas burner for cooking appliances, having overlapping main flame and simmering flame rings, includes an injector holder assembly associated with a first and a second injector and positioned below a cooktop opening; and a head assembly associated at the top with the injector holder assembly and positioned above the cooktop opening, the head assembly having a first chamber communicating with the first injector and with doors for ejecting the gas and primary air mixture supplied to the main flame ring, and a second chamber communicating with the second injector and with a passageway for ejecting the gas and primary air mixture supplied to the simmering flame ring. The second chamber communicates with a through opening in the outer side walls of the head assembly to receive primary air from above the cooktop, and the head assembly completely seals the cooktop opening where the gas burner is to be installed.

The present invention relates to a gas burner assembly (10), in particular for a gas cooking appliance, preferably for a domestic gas cooking hob. The present invention further relates to such a gas cooking appliance comprising at least one gas burner assembly (10). The gas burner assembly (10) comprises a burner head (12) including a plurality of high-power flame ports (32). The gas burner assembly (10) comprises at least one intermediate element (14, 16) including a plurality of low-power flame ports (38). The burner head (12) is arranged above the at least one intermediate element (14, 16). The high-power flame ports (32) are connected to a first gas inlet (30) via a horizontal Venturi pipe (22). The low-power flame ports (38) are connected to a second gas inlet (52) via an annular distribution chamber (46).
