Description
Die vorliegende Erfindung betrifft einen Gasbrenner für ein Haushaltsgargerät, eine Gasbrenneranordnung mit einem derartigen Gasbrenner und ein Haushaltsgargerät mit einem derartigen Gasbrenner und/oder einer derartigen Gasbrenneranordnung.The present invention relates to a gas burner for a domestic cooking appliance, a gas burner arrangement with such a gas burner and a domestic cooking appliance with such a gas burner and / or such a gas burner arrangement.
Gasbrenner für Haushaltsgargeräte umfassen zumeist ein Brennerunterteil, in dem eine Mischkammer vorgesehen sein kann, einen Düsenhalter, der eine Gasdüse zum Eindüsen von Brenngas in die Mischkammer aufweist, und einen auf das Brennerunterteil aufgelegten Brennerdeckel, der Gemischaustrittsöffnungen aufweist. Beim Eindüsen des Brenngases in die Mischkammer wird seitlich zwischen der Gasdüse und einer Einströmkante der Mischkammer Primärluft eingesaugt und mit dem Brenngas vermischt. Das so entstehende Brenngas-/Primärluftgemisch wird einer zwischen dem Brennerunterteil und dem Brennerdeckel vorgesehenen Gemischverteilkammer zugeführt und von dieser zur Flammenbildung gleichmäßig auf die Gemischaustrittsöffnungen verteilt. Um bei einem Erlöschen einer Brennerflamme des Gasbrenners eine erneute Zündung zu ermöglichen, kann ein derartiger Gasbrenner eine sogenannte Pilotflamme oder Zündflamme aufweisen, die über eine gesonderte Gaszuleitung mit Brenngas versorgt wird.Gas burners for household cooking appliances mostly comprise a burner base in which a mixing chamber can be provided, a nozzle holder which has a gas nozzle for injecting fuel gas into the mixing chamber, and a burner cover placed on the burner base which has mixture outlet openings. When the fuel gas is injected into the mixing chamber, primary air is sucked in laterally between the gas nozzle and an inflow edge of the mixing chamber and mixed with the fuel gas. The resulting fuel gas / primary air mixture is fed to a mixture distribution chamber provided between the lower part of the burner and the burner cover and is distributed evenly to the mixture outlet openings by this to form a flame. In order to enable renewed ignition when a burner flame of the gas burner goes out, such a gas burner can have a so-called pilot flame or ignition flame, which is supplied with fuel gas via a separate gas feed line.

Dabei steht die Speicherkammer mit Hilfe einer Zuführöffnung mit der Gemischverteilkammer in Fluidverbindung, wobei die Speicherkammer (34) ringförmig um die Gemischverteilkammer (22) umläuft, wobei die ringförmige Geometrie der Speicherkammer (34) offen ist, und wobei die Zündflammenöffnung an einem ersten Endabschnitt der Speicherkammer und die Zuführöffnung an einem dem ersten Endabschnitt gegenüberliegenden zweiten Endabschnitt der Speicherkammer vorgesehen ist.Accordingly, a gas burner for a domestic cooking appliance is proposed. The gas burner comprises a burner housing which has a large number of mixture outlet openings, from which, when the gas burner is in operation, a fuel gas / primary air mixture for generating a burner flame can be guided out into the surroundings of the gas burner, a mixture distribution chamber for evenly distributing the fuel gas / primary air mixture to the mixture outlet openings and a Includes storage chamber which is in fluid communication with the mixture distribution chamber in order to store part of the fuel gas / primary air mixture in the storage chamber during operation of the gas burner, the storage chamber comprising an ignition flame opening from which the fuel gas / primary air mixture stored in the storage chamber is used to generate a Pilot flame can be led out into the environment. The storage chamber is in fluid communication with the mixture distribution chamber with the aid of a feed opening, the storage chamber (34) running in a ring around the mixture distribution chamber (22), the ring-shaped geometry of the storage chamber (34) being open, and the ignition flame opening at a first end section of the Storage chamber and the feed opening is provided at a second end section of the storage chamber opposite the first end section.
Dadurch, dass die Speicherkammer zum Speichern des Brenngas-/Primärluftgemisches vorgesehen ist, kann die Zündflamme auch bei einer kurzfristigen Unterbrechung der Brenngaszufuhr und/oder einem Erlöschen der Brennerflamme, beispielsweise aufgrund eines Öffnens oder Schließens einer Tür des Haushaltsgargeräts, ohne eine zusätzliche Gaszuleitung zu der Zündflammenöffnung weiterbrennen, um die Brennerflamme wieder zu entzünden.Because the storage chamber is provided for storing the fuel gas / primary air mixture, the pilot flame can also be used in the event of a brief interruption in the fuel gas supply and / or the burner flame going out, for example due to the opening or closing of a door of the domestic cooking appliance, without an additional gas feed line to the Continue burning the pilot hole to re-ignite the burner flame.
Darunter, dass die Speicherkammer in Fluidverbindung mit der Gemischverteilkammer steht, ist zu verstehen, dass das Brenngas-/Primärluftgemisch von der Gemischverteilkammer in die Speicherkammer strömen kann. Die Speicherkammer ist von der Gemischverteilkammer getrennt. Das heißt, eine Wandung des Brennergehäuses ist zwischen der Gemischverteilkammer und der Speicherkammer vorgesehen.The fact that the storage chamber is in fluid connection with the mixture distribution chamber is to be understood as meaning that the fuel gas / primary air mixture can flow from the mixture distribution chamber into the storage chamber. The storage chamber is separated from the mixture distribution chamber. That is, a wall of the burner housing is provided between the mixture distribution chamber and the storage chamber.
Die Zündflamme kann auch als Pilotflamme bezeichnet werden. Die Speicherkammer kann dazu eingerichtet sein, das Brenngas-/Primärluftgemisch von Bruchteilen einer Sekunde bis zu mehreren Sekunden zu speichern, um die Zündflamme über diesen Zeitraum auch bei einer Unterbrechung der Brenngaszufuhr mit dem Brenngas-/Primärluftgemisch zu versorgen. Die Zündflammenöffnung kann eine Bohrung oder ein Durchbruch sein.The pilot flame can also be referred to as a pilot flame. The storage chamber can be set up to store the fuel gas / primary air mixture from fractions of a second up to several seconds in order to supply the ignition flame with the fuel gas / primary air mixture over this period even if the fuel gas supply is interrupted. The pilot flame opening can be a hole or a breakthrough.
Gemäß der Erfindung läuft die Speicherkammer ringförmig um die Gemischverteilkammer um.According to the invention, the storage chamber runs in a ring around the mixture distribution chamber.
Das heißt, die Gemischverteilkammer ist innerhalb der Speicherkammer angeordnet. Insbesondere kann die Speicherkammer in einer um die Gemischverteilkammer umlaufenden Wandung vorgesehen sein.That is, the mixture distribution chamber is arranged within the storage chamber. In particular, the storage chamber can be provided in a wall surrounding the mixture distribution chamber.
Gemäß der Erfindung ist die ringförmige Geometrie der Speicherkammer offen.According to the invention, the annular geometry of the storage chamber is open.
Hierunter ist zu verstehen, dass die Speicherkammer keinen geschlossenen Ring, sondern einen offenen Ring bildet, so dass die Speicherkammer einen Umfangswinkel von kleiner als 360° aufweist, beispielsweise von 300° bis 350°.This means that the storage chamber does not form a closed ring, but rather an open ring, so that the storage chamber has a circumferential angle of less than 360 °, for example from 300 ° to 350 °.
Gemäß einer weiteren Ausführungsform weist die Speicherkammer einen rechteckförmigen Querschnitt auf.According to a further embodiment, the storage chamber has a rectangular cross section.
Alternativ kann die Speicherkammer auch einen halbkreisförmigen oder einen kreisförmigen Querschnitt aufweisen. Die Querschnittsgeometrie der Speicherkammer ist grundsätzlich beliebig. Vorzugsweise weist die Speicherkammer jedoch einen rechteckförmigen Querschnitt auf und ist als rechteckförmige Nut in der zuvor erwähnten Wandung der Gemischverteilkammer vorgesehen.Alternatively, the storage chamber can also have a semicircular or circular cross section. The cross-sectional geometry of the storage chamber is basically arbitrary. However, the storage chamber preferably has a rectangular cross-section and is provided as a rectangular groove in the aforementioned wall of the mixture distribution chamber.
Gemäß einer weiteren Ausführungsform sind die Gemischverteilkammer und die Speicherkammer rotationssymmetrisch zu einer Symmetrieachse des Brennergehäuses aufgebaut.According to a further embodiment, the mixture distribution chamber and the storage chamber are constructed rotationally symmetrical to an axis of symmetry of the burner housing.
Insbesondere ist auch das Brennergehäuse im Wesentlichen rotationssymmetrisch zu der Symmetrieachse aufgebaut. Insbesondere verläuft die Gemischverteilkammer ringförmig um die Symmetrieachse herum. Die Speicherkammer umläuft wiederum ringförmig um die Gemischverteilkammer herum.In particular, the burner housing is also constructed essentially rotationally symmetrical to the axis of symmetry. In particular, the mixture distribution chamber runs in a ring around the axis of symmetry. The storage chamber in turn runs in a ring around the mixture distribution chamber.
Die Zuführöffnung ist insbesondere als Bohrung ausgebildet. Die Zuführöffnung kann einen kreisförmigen Querschnitt aufweisen. Alternativ kann die Zuführöffnung auch eine andere beliebige Geometrie aufweisen. Die Zuführöffnung kann einen anderen Durchmesser als die Zündflammenöffnung aufweisen. Beispielsweise kann ein Durchmesser der Zuführöffnung größer als ein Durchmesser der Zündflammenöffnung oder umgekehrt sein.The feed opening is designed in particular as a bore. The feed opening can have a circular cross section. Alternatively, the feed opening can also have any other geometry. The feed opening can have a different diameter than the pilot flame opening. For example, a diameter of the feed opening can be larger than a diameter of the pilot flame opening or vice versa.
Gemäß einer weiteren Ausführungsform bildet die Speicherkammer mit Ausnahme der Zündflammenöffnung und der Zuführöffnung einen von dem Brennergehäuse vollständig umschlossenen Hohlraum.According to a further embodiment, the storage chamber, with the exception of the ignition flame opening and the supply opening, forms a cavity completely enclosed by the burner housing.
Das heißt, die Speicherkammer bildet in dem Brennergehäuse bevorzugt eine vollständig umschlossene Kavität, die nur über die Zündflammenöffnung in Fluidverbindung mit der Umgebung und über die Zuführöffnung in Fluidverbindung mit der Gemischverteilkammer steht.That is, the storage chamber preferably forms a completely enclosed cavity in the burner housing, which is in fluid connection with the environment only via the ignition flame opening and in fluid connection with the mixture distribution chamber via the supply opening.
Wie zuvor erwähnt, umfasst die Speicherkammer eine offene ringförmige Geometrie. Der erste Endabschnitt und der zweite Endabschnitt liegen einander dabei gegenüber und sind um den größtmöglichen Abstand voneinander beabstandet angeordnet. Hierdurch muss das Brenngas-/Primärluftgemisch von der Zuführöffnung zu der Zündflammenöffnung einen möglichst großen Weg zurücklegen.As previously mentioned, the storage chamber comprises an open annular geometry. The first end section and the second end section lie opposite one another and are spaced apart from one another by the greatest possible distance. As a result, the fuel gas / primary air mixture must cover the greatest possible distance from the supply opening to the ignition flame opening.
Gemäß einer weiteren Ausführungsform umfasst das Brennergehäuse einen Düsenhalter, ein Brenneroberteil und einen Brennerdeckel, wobei das Brennerunterteil zwischen dem Düsenhalter und dem Brennerdeckel angeordnet ist.According to a further embodiment, the burner housing comprises a nozzle holder, an upper burner part and a burner cover, the lower burner part being arranged between the nozzle holder and the burner cover.
Insbesondere ist das Brennerunterteil fest mit dem Düsenhalter verbunden. Der Brennerdeckel ist lose auf das Brennerunterteil aufgelegt. Beispielsweise ist das Brennerunterteil mit dem Düsenhalter verschraubt. Zwischen dem Brennerunterteil und dem Düsenhalter kann eine Kochfeldplatte mit einem Durchbruch vorgesehen sein. Der Gasbrenner ist dann durch den Durchbruch hindurchgeführt. Die Kochfeldplatte ist bevorzugt zwischen dem Düsenhalter und dem Brennerunterteil festgeklemmt.In particular, the lower part of the burner is firmly connected to the nozzle holder. The burner cap is loosely placed on the lower part of the burner. For example, the lower part of the burner is screwed to the nozzle holder. A hob plate with an opening can be provided between the lower burner part and the nozzle holder. The gas burner is then passed through the opening. The hob plate is preferably clamped between the nozzle holder and the lower burner part.
Gemäß einer weiteren Ausführungsform sind die Gemischverteilkammer und die Speicherkammer in dem Brennerunterteil vorgesehen.According to a further embodiment, the mixture distribution chamber and the storage chamber are provided in the lower burner part.
Das Brennerunterteil, der Düsenhalter und der Brennerdeckel sind vorzugsweise voneinander getrennte Bauteile. Das Brennerunterteil, der Brennerdeckel und der Düsenhalter können beispielsweise als Aluminiumdruckgussbauteile oder als Magnesiumdruckgussbauteile ausgeführt sein.The lower part of the burner, the nozzle holder and the burner cover are preferably separate components. The lower part of the burner, the burner cover and the nozzle holder can be designed, for example, as aluminum die-cast components or as magnesium die-cast components.
Gemäß einer weiteren Ausführungsform weist das Brennergehäuse eine Verschlussplatte auf, die die Speicherkammer in Richtung des Düsenhalters verschließt.According to a further embodiment, the burner housing has a closure plate which closes the storage chamber in the direction of the nozzle holder.
Die Verschlussplatte ist beispielsweise mit dem Brennerunterteil verklebt, verschweißt, verschraubt, vernietet oder verstemmt. Die Verschlussplatte ist beispielsweise eine Stahlplatte. Die Verschlussplatte ist dem Brennerunterteil zugeordnet und ist Teil des Brennerunterteils. Die Speicherkammer ist bevorzugt als in dem Brennerunterteil vorgesehene Nut ausgebildet, die mit Hilfe der Verschlussplatte verschlossen ist.The closure plate is, for example, glued, welded, screwed, riveted or caulked to the lower part of the burner. The closure plate is, for example, a steel plate. The closure plate is assigned to the lower part of the burner and is part of the lower part of the burner. The storage chamber is preferably designed as a groove provided in the lower burner part, which is closed with the aid of the closure plate.
Gemäß einer weiteren Ausführungsform umfasst das Brennerunterteil eine mit der Gemischverteilkammer in Fluidverbindung stehende Mischkammer zum Mischen von Brenngas mit Primärluft, wobei sich die Mischkammer zumindest teilweise durch die Gemischverteilkammer hindurch erstreckt.According to a further embodiment, the lower burner part comprises a mixing chamber, which is in fluid communication with the mixture distribution chamber, for mixing fuel gas with primary air, the mixing chamber extending at least partially through the mixture distribution chamber.
Insbesondere mündet die Mischkammer in die Gemischverteilkammer hinein. Das Brennerunterteil umfasst vorzugsweise einen scheibenförmigen Basisabschnitt, an dem mittig die Mischkammer vorgesehen ist. Die Mischkammer wird bevorzugt von einer umlaufenden Wandung begrenzt.In particular, the mixing chamber opens into the mixture distribution chamber. The lower burner part preferably comprises a disk-shaped base section on which the mixing chamber is provided in the center. The mixing chamber is preferably delimited by a circumferential wall.
Gemäß einer weiteren Ausführungsform umfasst der Düsenhalter eine Gasdüse zum Eindüsen von Brenngas in die Mischkammer, wobei die Gasdüse beabstandet von einer Einströmkante der Mischkammer angeordnet ist.According to a further embodiment, the nozzle holder comprises a gas nozzle for injecting fuel gas into the mixing chamber, the gas nozzle being arranged at a distance from an inflow edge of the mixing chamber.
Das heißt, die Gasdüse ist außerhalb der Mischkammer angeordnet. Im Betrieb des Gasbrenners düst die Gasdüse das Brenngas in die Mischkammer ein, wodurch seitlich an der Gasdüse vorbei Primärluft in die Mischkammer eingesaugt und dort mit dem Brenngas zu dem Brenngas-/Primärluftgemisch vermischt wird.That is, the gas nozzle is arranged outside the mixing chamber. When the gas burner is in operation, the gas nozzle injects the fuel gas into the mixing chamber, as a result of which primary air is sucked past the side of the gas nozzle into the mixing chamber and is mixed there with the fuel gas to form the fuel gas / primary air mixture.
Weiterhin wird eine Gasbrenneranordnung mit einer Kochfeldplatte und zumindest einem derartigen Gasbrenner vorgeschlagen, der an der Kochfeldplatte montiert ist.Furthermore, a gas burner arrangement with a hob plate and at least one such gas burner is proposed, which is mounted on the hob plate.
Die Gasbrenneranordnung kann eine beliebige Anzahl an Gasbrennern umfassen. Die Kochfeldplatte kann beispielsweise eine Stahlplatte, eine Glaskeramikplatte oder eine Platte aus getempertem Glas sein.The gas burner arrangement can comprise any number of gas burners. The hob plate can be, for example, a steel plate, a glass ceramic plate or a plate made of tempered glass.
Ferner wird ein Haushaltsgargerät, insbesondere ein Gasherd, mit einem derartigen Gasbrenner oder einer derartigen Gasbrenneranordnung vorgeschlagen.Furthermore, a domestic cooking appliance, in particular a gas stove, with such a gas burner or such a gas burner arrangement is proposed.
Vorzugsweise weist das Haushaltsgargerät eine Vielzahl derartiger Gasbrenner auf. Jedem Gasbrenner kann ein Gasregelventil oder Gassteuerventil zugeordnet sein. Das Gassteuerventil kann dazu eingerichtet sein, einen Brenngasvolumenstrom zu der Gasdüse stufenlos oder gestuft zu regeln. Das Gassteuerventil kann auch ein sogenanntes Step Valve sein. Das Haushaltsgargerät kann ein Standgerät oder ein Einbaugerät sein. Vorzugsweise ist das Haushaltsgargerät ein Haushaltsgasherd. Beispielsweise kann das Haushaltsgargerät vier derartige Gasbrenner aufweisen. Das Gassteuerventil ist an einer Hauptgasleitung des Haushaltsgargeräts angeklemmt und über eine Gaszuleitung mit dem ihm zugeordneten Gasbrenner fluidisch verbunden. Weiterhin können jedem Gasbrenner noch eine Zündeinrichtung, die in das Gassteuerventil integriert sein kann, und ein direkt an dem Gasbrenner angeordnetes Zündelement, beispielsweise eine Zündkerze, zugeordnet sein. Weiterhin kann jeder Gasbrenner noch ein Thermoelement zur Flammenüberwachung aufweisen. Das Thermoelement ist mit dem Gassteuerventil des jeweiligen Gasbrenners elektrisch verbunden.The domestic cooking appliance preferably has a large number of such gas burners. A gas control valve or gas control valve can be assigned to each gas burner. The gas control valve can be set up to regulate a fuel gas volume flow to the gas nozzle continuously or in steps. The gas control valve can also be a so-called step valve. The household cooking appliance can be a free-standing appliance or a built-in appliance. The domestic cooking appliance is preferably a domestic gas stove. For example, the household cooking appliance can have four such gas burners. The gas control valve is clamped to a main gas line of the domestic cooking appliance and fluidly connected to the gas burner assigned to it via a gas supply line. Furthermore, an ignition device, which can be integrated into the gas control valve, and an ignition element arranged directly on the gas burner, for example a spark plug, can be assigned to each gas burner. Furthermore, each gas burner can also have a thermocouple for flame monitoring. The thermocouple is electrically connected to the gas control valve of the respective gas burner.
