Definitions

  • the present invention relates to a gas burner for a household cooking appliance and a household cooking appliance with such a gas burner.
  • Gas burners for household cooking appliances comprise a burner lower part in which a mixing chamber is provided in the center, and a nozzle holder which has a gas nozzle for injecting fuel gas into the mixing chamber.
  • a mixing chamber is provided in the center
  • a nozzle holder which has a gas nozzle for injecting fuel gas into the mixing chamber.
  • the WO 2010/105515 discloses a gas burner for a domestic cooking appliance, with a burner housing having a mixing chamber for mixing fuel gas with primary air, and a gas nozzle accommodated in the burner housing for injecting the fuel gas into the mixing chamber, an almost annular first primary air inlet between the gas nozzle and the mixing chamber Sucking in the primary air is provided, the gas nozzle having a second primary air inlet through which it is drawn in order to flow through the primary air, the second primary air inlet tapering and widening at least once in a direction of flow of the primary air through the second primary air inlet, and wherein the gas nozzle has an annular fuel gas outlet opening having.
  • an object of the present invention is to provide an improved gas burner.
  • the gas burner comprises a burner housing which has a mixing chamber for mixing fuel gas with primary air, and a gas nozzle accommodated in the burner housing for injecting the fuel gas into the mixing chamber, an annular first primary air inlet for sucking primary air being provided between the gas nozzle and the mixing chamber.
  • the gas nozzle has a second primary air inlet for sucking primary air through it, the second primary air inlet tapering and widening at least once in a flow direction of the primary air through the second primary air inlet, and wherein the gas nozzle has an annular fuel gas outlet opening that directly into the second Primary air inlet opens into it.
  • An annular fuel gas outlet opening is to be understood to mean that the fuel gas outlet opening rotates completely around a central or symmetry axis of the gas burner.
  • the fuel gas outlet opening is in particular slit-shaped.
  • the fact that the second primary air inlet tapers in the flow direction of the primary air means that a cross-sectional area of the second primary air inlet is reduced. That is, a diameter of the second primary air inlet is reduced in the flow direction.
  • a cross-sectional area of the second primary air inlet increases. That is, a diameter of the second primary air inlet increases in the flow direction.
  • the second primary air inlet thus has a restriction or constriction, in front of which the second primary air inlet tapers and after which the second primary air inlet widens again. This can accelerate the primary air in the gas nozzle.
  • Air in particular the aforementioned primary air and secondary air, is required to burn the fuel gas.
  • the gas nozzle injects the fuel gas into the mixing chamber, which is particularly open at the bottom. The injection of the fuel gas creates a Venturi effect and the primary air is drawn through the gas nozzle via the second primary air inlet and simultaneously drawn past the gas nozzle through the first primary air inlet into the mixing chamber, where it is mixed with the fuel gas to form a primary air / fuel gas mixture.
  • the secondary air is the air that is required to burn the primary air / fuel gas mixture emerging from the gas burner.
  • the fuel gas can already be mixed with the primary air in the gas nozzle. Furthermore, by providing two primary air inlets, the amount of primary air drawn in can be increased. This enables the combustion of a larger amount of fuel gas. This can increase the performance of the gas burner. Because the fuel gas and the primary air are already at least partially mixed in the gas nozzle, an overall height of the gas burner can be reduced compared to known gas burners. The better mixing of the primary air with the fuel gas increases the efficiency of the gas burner and reduces pollutant emissions.
  • the gas burner can also be referred to as a household gas burner or household cooking appliance gas burner.
  • the fuel gas outlet opening breaks through an outer wall of the second primary air inlet.
  • the fuel gas outlet opening opens laterally into the second primary air inlet.
  • the gas nozzle has an annular fuel gas distribution channel, the fuel gas distribution channel tapering in the direction of the fuel gas outlet opening.
  • the fuel gas distribution channel is preferably rotationally symmetrical to the central axis of the gas burner. This means that the fuel gas distribution channel runs completely around the central axis.
  • a connecting channel is provided between the fuel gas outlet opening and the fuel gas distribution channel, which can be curved in an arc shape, in particular in a circular arc shape.
  • the fact that the fuel gas distribution channel tapers in the direction of the fuel gas outlet opening means that a cross-sectional area of the fuel gas distribution channel is larger than a cross-sectional area of the fuel gas outlet opening.
  • the second primary air inlet has an inlet section which tapers conically in the flow direction of the primary air, an outlet section which widens conically in the flow direction and faces the mixing chamber, and an intermediate cylindrical section arranged between the inlet section and the outlet section.
  • the intermediate section preferably has a circular cross-sectional area.
  • the intermediate section forms a constriction or a throttle point of the second primary air inlet.
  • the fact that the inlet section tapers conically in the flow direction of the primary air means that a cross section or a cross-sectional area of the inlet section decreases in the flow direction.
  • the fact that the outlet section widens conically in the flow direction means that a cross section or a cross-sectional area of the outlet section increases in the flow direction.
  • the fuel gas outlet opening opens into the second primary air inlet between the intermediate section and the outlet section.
  • the fuel gas outlet opens into the second primary air inlet immediately after the intermediate section. This means that the fuel gas is immediately after the constriction of the second primary air inlet injected. This enables particularly good mixing of the fuel gas with the primary air already in the gas nozzle.
  • the gas nozzle is rotationally symmetrical to a central axis, the second primary air inlet likewise being rotationally symmetrical to the central axis.
  • the gas nozzle preferably has a base body formed from a metal material.
  • the gas nozzle can be made of brass.
  • the fuel gas distribution channel is also provided in the base body.

  • the gas burner can be inexpensively manufactured in large numbers.
  • the gas burner is mounted on a cover plate or on a so-called top sheet.
  • the cover plate can be arranged between the nozzle holder and the lower part of the burner. All gas burners of the household cooking appliance are assigned to the cover plate. This means that the household cooking appliance has only one cover plate on which all gas burners are mounted.
  • the nozzle holder has a fuel gas channel for supplying the fuel gas to the gas nozzle.
  • a fuel gas distribution channel can also be provided in the nozzle holder, into which the fuel gas channel opens.
  • the fuel gas distribution channel can be designed in a ring shape and circulate around the second primary air inlet.
  • the fuel gas distribution channel of the nozzle holder can be in fluid communication with the fuel gas distribution channel of the gas nozzle via connecting channels.
  • the second primary air inlet is at least partially formed in the nozzle holder.
  • a suction section tapering in the direction of flow of the primary air and a supply section for supplying the primary air sucked in through the suction section to the gas nozzle can be provided in the nozzle holder.
  • a household cooking appliance in particular a gas stove, with such a gas burner is also proposed.
