Description

Die vorliegende Erfindung betrifft eine Gaskochmulde.The present invention relates to a gas hob.

Die DE 100 64 450 beschreibt ein KĆ¼chenmƶbel mit einer Arbeitsplatte und einer darin integrierten Gaskochmulde. Die Gaskochmulde weist mehrere Brenner auf, welche mittels einer oberhalb der Arbeitsplatte angeordneten Ɩffnung mit PrimƤrluft versorgt werden. Diese Ɩffnung ist jedoch von Ƥsthetischem Nachteil.The DE 100 64 450 describes a kitchen furniture with a worktop and a built-in gas hob. The gas hob has a plurality of burners, which are supplied by means of a arranged above the worktop opening with primary air. However, this opening is of aesthetic disadvantage.

Vor diesem Hintergrund besteht eine Aufgabe der vorliegenden Erfindung darin, eine verbesserte Gaskochmulde zu schaffen.Against this background, an object of the present invention is to provide an improved gas hob.

DemgemƤƟ wird eine Gaskochmulde mit einem Brenner und einer Einrichtung zum Reduzieren von Druckschwankungen in einem dem Brenner zugefĆ¼hrten PrimƤrluftstrom vorgeschlagen. Die Einrichtung kehrt eine Strƶmungsrichtung des PrimƤrluftstroms zumindest einmal um.Accordingly, a gas hob with a burner and a device for reducing pressure fluctuations in a primary air flow supplied to the burner is proposed. The device reverses a flow direction of the primary air flow at least once.

Weiterhin wird ein KĆ¼chenmƶbel mit der vorstehenden Gaskochmulde und einem Innenraum vorgeschlagen. Die Einrichtung zum Reduzieren von Druckschwankungen ist luftleitend mit dem Innenraum verbunden, um dem Brenner den PrimƤrluftstrom zuzufĆ¼hren.Furthermore, a kitchen furniture with the above gas hob and an interior is proposed. The means for reducing pressure fluctuations is air-conductively connected to the interior to supply the burner with the primary air flow.

Auf Grund der Einrichtung zum Reduzieren von Druckschwankungen kann eine Zufuhr der PrimƤrluft von unterhalb der eingangs genannten Arbeitsplatte erfolgen. Denn Druckschwankungen, welche sich beispielsweise aus einem Ɩffnen oder SchlieƟen eines Schubladens oder einer TĆ¼r unterhalb der Arbeitsplatte ergeben, werden von der Einrichtung abgepuffert und bleiben damit ohne wesentlichen Einfluss auf den Brenner.Due to the device for reducing pressure fluctuations, a supply of the primary air can be carried out from below the worktop mentioned above. Because pressure fluctuations, resulting for example from an opening or closing a drawer or a door below the worktop are buffered by the device and thus remain without significant influence on the burner.

Dadurch, dass die Zufuhr der PrimƤrluft von unterhalb der Arbeitsplatte erfolgen kann, lassen sich Ƥsthetisch ansprechende Lƶsungen erzielen.The fact that the supply of primary air can be done from below the worktop, can be aesthetically pleasing solutions.

In einer AusfĆ¼hrungsform weist die Einrichtung fĆ¼r das Umkehren der Strƶmungsrichtung des PrimƤrluftstroms ein Labyrinth auf. Insbesondere ergibt sich somit ein meanderfƶmiger Gang, durch welchen der PrimƤrluftstrom gezwungen wird.In one embodiment, the device for reversing the flow direction of the primary air flow has a labyrinth. In particular, this results in a meanderfƶmiger gear through which the primary air flow is forced.

In einer weiteren AusfĆ¼hrungsform weist die Einrichtung zwei kammartige Abschnitte auf, welche das Labyrinth zwischen sich definieren und dazu mehrere ZƤhne umfassen, die ineinander greifen. Somit lƤsst sich das Labyrinth einfach herstellen. Beispielsweise kann der eine kammartige Abschnitt mehrere ZƤhne aufweisen, welche jeweils in einen zwischen jeweils zwei ZƤhnen des anderen kammartigen Abschnitts gebildeten Zwischenraum greifen. GrundsƤtzlich ist es jedoch auch mƶglich, dass der eine kammartige Abschnitt lediglich einen Zahn aufweist.In a further embodiment, the device has two comb-like sections which define the labyrinth between them and for this purpose comprise a plurality of teeth which mesh with one another. Thus, the labyrinth can be easily produced. For example, the one comb-like portion may have a plurality of teeth each engaging in a space formed between each two teeth of the other comb-like portion. In principle, however, it is also possible for the one comb-like section to have only one tooth.

In einer weiteren AusfĆ¼hrungsform weist die Einrichtung ein zumindest teilweise in dem PrimƤrluftstrom angeordnetes Element auf, welches reibungsbehaftet beweglich ausgebildet ist. Ein entsprechender Reibwert ist fĆ¼r das Reduzieren der Druckschwankungen geeignet vorgesehen. Sowie sich das Element unter dem Einfluss der Druckschwankungen bewegt, baut es die Druckschwankungen in einer Richtung hin zu dem Brenner ab.In a further embodiment, the device has an element which is arranged at least partially in the primary air flow and which is designed to be movable in terms of friction. A corresponding coefficient of friction is provided for reducing the pressure fluctuations suitable. As the element moves under the influence of pressure fluctuations, it reduces pressure fluctuations in a direction toward the burner.

In einer weiteren AusfĆ¼hrungsform ist das Element als Klappe ausgebildet, reibungsbehaftet schwenkbar angelenkt ist. Eine solche Klappe ist einfach herzustellen.In a further embodiment, the element is designed as a flap, hinged hinged with friction. Such a flap is easy to produce.

In einer weiteren AusfĆ¼hrungsform ist in dem PrimƤrluftstrom ein porƶses Material angeordnet. Das porƶse Element kann als porƶse Keramik oder als porƶser Kunststoff ausgebildet sein. Das porƶse Material ist ebenfalls dazu geeignet, Druckschwankungen in dem PrimƤrluftstrom abzubauen.In a further embodiment, a porous material is arranged in the primary air flow. The porous element may be formed as a porous ceramic or as a porous plastic. The porous material is also suitable for reducing pressure fluctuations in the primary air flow.

In einer weiteren AusfĆ¼hrungsform weist die Einrichtung eine Austrittsƶffnung hin zum dem Brenner auf. Bevorzugt weist die Austrittsƶffnung dabei in einen zwischen einer Kochfeldplatte und einer Wanne der Gaskochmulde gebildeten Raum, mit welchem der Brenner luftleitend verbunden ist.In a further embodiment, the device has an outlet opening towards the burner. Preferably, the outlet opening in this case in a space formed between a cooking plate and a trough of the gas hob, with which the burner is connected in air conduction.

In einer weiteren AusfĆ¼hrungsform ist die Klappe im Bereich der Austrittsƶffnung angeordnet und/oder verschlieƟt die Austrittsƶffnung zumindest abschnittsweise. Eine solche Klappe lƤsst sich einfach montieren.In a further embodiment, the flap is arranged in the region of the outlet opening and / or closes the outlet opening at least in sections. Such a flap can be easily mounted.

In einer weiteren AusfĆ¼hrungsform verschlieƟt das porƶse Material die Austrittsƶffnung. Diese Anordnung des porƶsen Materials ist einfach herzustellen.In a further embodiment, the porous material closes the outlet opening. This arrangement of the porous material is easy to manufacture.

In einer weiteren AusfĆ¼hrungsform weist die Gaskochmulde eine Kochfeldplatte auf, an welcher unterseitig eine Wanne angeordnet ist. Die Wanne dichtet bevorzugt luftdicht gegen die Kochfeldplatte ab und weist lediglich eine Ɩffnung auf, mittels derer die PrimƤrluft durch die Einrichtung zum Reduzieren von Druckschwankungen zu dem Brenner gelangt. In einer weiteren AusfĆ¼hrungsform ist die Einrichtung zumindest abschnittsweise in einem von der Kochfeldplatte und der Wanne umschlossenen Raum angeordnet. Dadurch lƤsst sich die Einrichtung einfach und geschĆ¼tzt in der Gaskochmulde unterbringen.In a further embodiment, the gas hob has a hob plate on which a tray is arranged on the underside. The pan preferably seals airtight against the cooking field plate and has only one opening by means of which the primary air passes through the means for reducing pressure fluctuations to the burner. In a further embodiment, the device is arranged at least in sections in a space enclosed by the hob plate and the tub. As a result, the device can be accommodated easily and protected in the gas hob.

In einer weiteren AusfĆ¼hrungsform weist die Einrichtung eine Eintrittsƶffnung auf, welche durch eine Ɩffnung in der Wanne hindurch mit der Umgebungsluft verbunden ist. Die "Ɩffnung in der Wanne" umfasst bevorzugt auch den Fall, dass die Ɩffnung lediglich von der Wanne begrenzt wird und nicht vollstƤndig in dieser ausgebildet ist.In a further embodiment, the device has an inlet opening, which is connected to the ambient air through an opening in the trough. The "opening in the tub" preferably also includes the case that the opening is limited only by the tub and is not completely formed in this.

In einer weiteren AusfĆ¼hrungsform ist der Innenraum mit der Ɩffnung in der Wanne luftleitend verbunden. Luft auƟerhalb des Innenraums gelangt somit nicht zu der Ɩffnung in der Wanne.In a further embodiment, the interior is connected in an air-conducting manner with the opening in the trough. Air outside the interior thus does not get to the opening in the tub.

In einer weiteren AusfĆ¼hrungsform ist die Gaskochmulde in eine Arbeitsplatte integriert, unterhalb welcher der Innenraum gebildet ist. Der Innenraum kann Schubladen aufweisen oder mittels TĆ¼ren von auƟen zugƤnglich sein.In a further embodiment, the gas hob is integrated in a worktop, below which the interior is formed. The interior may have drawers or be accessible by doors from the outside.

Weitere mƶgliche Implementierungen der Erfindung umfassen auch nicht explizit genannte Kombinationen von zuvor oder im Folgenden bezĆ¼glich der AusfĆ¼hrungsbeispiele beschriebenen Merkmale oder AusfĆ¼hrungsformen der Gaskochmulde oder des KĆ¼chenmƶbels. Dabei wird der Fachmann auch Einzelaspekte als Verbesserungen oder ErgƤnzungen zu der jeweiligen Grundform der Erfindung hinzufĆ¼gen oder abƤndern.Further possible implementations of the invention also include not explicitly mentioned combinations of features or embodiments of the gas hob or of the kitchen appliance described above or below with regard to the exemplary embodiments. The skilled person will also add or modify individual aspects as improvements or additions to the respective basic form of the invention.

Weitere vorteilhafte Ausgestaltungen und Aspekte der Erfindung sind Gegenstand der UnteransprĆ¼che sowie der im Folgenden beschriebenen AusfĆ¼hrungsbeispiele der Erfindung. Im Weiteren wird die Erfindung anhand von bevorzugten AusfĆ¼hrungsformen unter Bezugnahme auf die beigelegten Figuren nƤher erlƤutert.Further advantageous embodiments and aspects of the invention are the subject of the dependent claims and the embodiments of the invention described below.

Fig. 1 zeigt in einer perspektivischen Ansicht ausschnittsweise ein KĆ¼chenmƶbel 1. Fig. 2 zeigt perspektivisch eine ausgebrochen dargestelltes Detail aus Fig. 1. Fig. 1 shows in a perspective view fragmentary a kitchen furniture. 1 Fig. 2 shows in perspective a broken-out detail shown Fig. 1 ,

Das KĆ¼chenmƶbel 1 weist eine Arbeitplatte 2 auf, in welche eine Gaskochmulde 3 integriert ist. Unterhalb der Arbeitsplatte 2 ist ein Innenraum 4 gebildet, welcher nicht dargestellte Schubladen oder TĆ¼ren aufweisen kann.The kitchen furniture 1 has a worktop 2, in which a gas hob 3 is integrated. Below the worktop 2, an interior 4 is formed, which may have drawers or doors, not shown.

Die Gaskochmulde 3 umfasst einen Brenner 5 zum Beheizen eines nicht dargestellten GargutbehƤlters oder dergleichen Ć¼ber einer offenen Flamme. SelbstverstƤndlich kann die Gaskochmulde 3 auch mehrere Brenner 5 aufweisen. Die Gaskochmulde 3 weist ferner eine Kochfeldplatte 6 auf, aus welcher der Brenner 5 oberseitig herausragt. Die Kochfeldplatte 6 ist in Fig. 1 ausgebrochen dargestellt, um die darunter liegenden Details sichtbar zu machen. Unterseitig ist die Gaskochmulde 3 mit einer Wanne 7 gebildet, welche einen Raum 11 zusammen mit der Kochfeldplatte 6 begrenzt und gegen diese mittels eines umlaufenden Flanschs 12 luftdicht abdichtet. Der Brenner 5 wird fĆ¼r den Verbrennungsprozess mit PrimƤrluft (ein entsprechender PrimƤrluftstrom ist mit 13 bezeichnet) aus dem Innenraum 4 versorgt.The gas hob 3 comprises a burner 5 for heating a cooking utensil (not shown) or the like over an open flame. Of course, the gas hob 3 may also have a plurality of burners 5. The gas hob 3 also has a hob plate 6, from which the burner 5 protrudes from the top. The hob plate 6 is in Fig. 1 broken out to reveal the underlying details. On the underside, the gas hob 3 is formed with a trough 7, which defines a space 11 together with the hob plate 6 and seals against these by means of a peripheral flange 12 airtight. The burner 5 is supplied from the interior 4 for the combustion process with primary air (a corresponding primary air flow is denoted by 13).

Die Gaskochmulde 3 weist weiterhin eine Einrichtung 14 zum Reduzieren von Druckschwankungen in dem PrimƤrluftstrom 13 auf. Druckschwankungen in dem Innenraum 4, welche sich beispielsweise durch ein Ɩffnen oder SchlieƟen der Schubladen oder TĆ¼ren ergeben, kƶnnen sich somit nicht mehr bis hin zu dem Brenner 5 fortpflanzen bzw. kƶnnen den Brenner 5 nicht mehr in seiner Funktion beeintrƤchtigen.The gas hob 3 also has a device 14 for reducing pressure fluctuations in the primary air flow 13. Pressure fluctuations in the interior 4, which result, for example, by opening or closing the drawers or doors, can thus no longer propagate as far as the burner 5 or can no longer impair the function of the burner 5.

Die Einrichtung 14 umfasst zwei kammartige Abschnitte 15, 16, insbesondere aus Blech oder Kunststoff. Die Abschnitte 15, 16 umfassen jeweils mehrere ZƤhne 17, 18. Beispielsweise kann der eine Abschnitt 15 drei ZƤhne 17 und der andere Abschnitt 16 vier ZƤhne 18 aufweisen. Die ZƤhne 17, 18 kƶnnen sich beispielsweise senkrecht (also in Schwerkraftrichtung) erstrecken. Ein jeweiliger Zahn 17 des einen Abschnitts 15 greift in einen zwischen jeweils zwei ZƤhnen 18 des anderen Abschnitts 16 gebildeten Zwischenraum 21. Dadurch entsteht ein Labyrinth in Form eines meanderfƶrmigen Gangs 20 mit einer Eintrittsƶffnung 22 und einer Austrittsƶffnung 23, durch welchen der PrimƤrluftstrom 13 von der Eintritts- zur Austrittsƶffnung 22, 23 strƶmen muss, um von dem Innenraum 4 hin zu dem Brenner 5 zu gelangen. In dem meanderfƶrmigen Gang 20 kehrt sich die Strƶmungsrichtung 24, 24' des PrimƤrluftstroms 13 mehrfach, beispielsweise sechsmal um. Mit "Strƶmungsumkehr" ist gemeint, dass eine zweite Strƶmungsrichtung 24' insgesamt oder zumindest eine Bewegungskomponente derselben einer ersten Strƶmungsrichtung 24 entgegengerichtet ist. Aufgrund der sich ergebenden mehrfachen Strƶmungsumkehr, werden Druckschwankungen in dem Innenraum 4 nur stark abgepuffert an den Brenner 5 weitergegeben. Der meanderfƶrmige Gang 20 ist hinsichtlich seiner Gestalt, beispielsweise hinsichtlich seines Querschnitts, optimal an die gewĆ¼nschte Reduzierung der Druckschwankungen angepasst.The device 14 comprises two comb-like sections 15, 16, in particular of sheet metal or plastic. The sections 15, 16 each comprise a plurality of teeth 17, 18. For example, one section 15 may have three teeth 17 and the other section 16 may have four teeth 18. The teeth 17, 18 may, for example, extend vertically (ie in the direction of gravity). A respective tooth 17 of the one section 15 engages in a gap 21 formed between two respective teeth 18 of the other section 16. This results in a labyrinth in the form of a meandering passage 20 with an inlet opening 22 and an outlet opening 23, through which the primary air flow 13 of the Entrance to the outlet opening 22, 23 must flow in order to get from the interior 4 to the burner 5. In the meandering passage 20, the flow direction 24, 24 'of the primary air flow 13 is reversed several times, for example six times. By "flow reversal" is meant that a second flow direction 24 'as a whole or at least a component of movement thereof is opposite to a first flow direction 24. Due to the resulting multiple flow reversal, pressure fluctuations in the interior 4 are only greatly buffered passed to the burner 5. The meandering passage 20 is optimally adapted to the desired reduction in pressure fluctuations in terms of its shape, for example in terms of its cross-section.

Die Abschnitte 15, 16 sind Teil eines luftdicht geschlossenen GehƤuses, welches lediglich an seiner einen Seite hin zu dem Innenraum 4 die Eintrittsƶffnung 22 und an seiner anderen Seite hin zu dem Brenner 5 bzw. hin zu dem zwischen der Kochfeldplatte 6 und der Wanne 7 gebildeten Zwischenraum 11 die Austrittsƶffnung 23 aufweist. Die Eintrittsƶffnung 22 steht mittels einer Ɩffnung 25 in der Wanne 7 mit dem Innenraum 4 in luftleitender Verbindung. Ein die Eintrittsƶffnung 22 aufweisender Abschnitt 26 des GehƤuses kann direkt gegen eine vertikale Wandung 27 der Wanne 7 anliegen. Die Wandung 27 verbindet einen Boden 31 der Wanne 7 mit dem Flansch 12 derselben.The sections 15, 16 are part of a hermetically sealed housing, which on its one side only to the interior 4, the inlet opening 22 and on its other side to the burner 5 and towards the between the cooking plate 6 and the trough 7 formed Interspace 11, the outlet opening 23 has. The inlet opening 22 is by means of an opening 25 in the trough 7 with the interior 4 in air-conducting connection. A the inlet opening 22 exhibiting portion 26 of the housing can bear directly against a vertical wall 27 of the trough 7. The wall 27 connects a bottom 31 of the tub 7 with the flange 12 thereof.

Fig. 3 zeigt in schematischer Schnittansicht eine Einrichtung 14 zur Reduzieren von Druckschwankungen gemƤƟ einem weiteren AusfĆ¼hrungsbeispiel. Fig. 3 shows a schematic sectional view of a device 14 for reducing pressure fluctuations according to another embodiment.

Die Einrichtung 14 gemƤƟ Fig. 3 unterscheidet sich von der gemƤƟ den Fig. 2 und 3 dadurch, dass sich die ZƤhne 17, 18 waagerecht oder von der Waagerechten geringfĆ¼gig abweichend erstrecken. Beispielsweise kƶnnen sich die ZƤhne 17, 18 unter einem Winkel 32 von beispielsweise zwischen 1 und 10 Grad abweichend von der Waagerechten erstrecken.The device 14 according to Fig. 3 is different from that according to the Fig. 2 and 3 in that the teeth 17, 18 extend horizontally or slightly deviating from the horizontal. For example, the teeth 17, 18 may extend at an angle 32 of, for example, between 1 and 10 degrees other than the horizontal.

Weiterhin zeigt Fig. 3, dass die ZƤhne 17, 18 einen Knick 30 aufweisen kƶnnen, wie beispielhaft an einem Zahn 18 illustriert.Further shows Fig. 3 in that the teeth 17, 18 may have a bend 30, as exemplified by a tooth 18.

Fig. 4 zeigt in schematischer Schnittansicht eine Einrichtung 14 zum Reduzieren von Druckschwankungen gemƤƟ einem noch weiteren AusfĆ¼hrungsbeispiel. Fig. 4 shows a schematic sectional view of a device 14 for reducing pressure fluctuations according to yet another embodiment.

Die Einrichtung 14 gemƤƟ Fig. 4 weist gegenĆ¼ber der Einrichtung 14 gemƤƟ Fig. 3 zusƤtzlich eine Klappe 33 auf. Die Klappe 33 ist mittels eines reibungsbehafteten Scharniers 34 schwenkbar angelenkt. Die Klappe 33 verschlieƟt in dem dargestellten, normalen Betriebszustand die Austrittsƶffnung 23 lediglich teilweise. "Normal" meint hier, dass eine definierte PrimƤrluftstrƶmung durch die Einrichtung 14 zum Brenner 5 besteht, um fĆ¼r eine wunschgemƤƟe Verbrennung zu sorgen. Kommt es nun zu einer Druckschwankung in dem Innenraum 4, so verschwenkt die Klappe 33 mittels des Scharniers 34. Der Reibwert des Scharniers 34 ist derart vorgesehen, dass die Druckschwankung geeignet reduziert wird.The device 14 according to Fig. 4 points towards the device 14 according to Fig. 3 in addition, a flap 33. The flap 33 is hinged by means of a frictional hinge 34 pivotally. The flap 33 closes in the illustrated, normal operating state, the outlet opening 23 only partially. "Normal" here means that a defined primary air flow through the device 14 to the burner 5 is to provide for a desired combustion. If there is now a pressure fluctuation in the interior 4, then the flap 33 pivots by means of the hinge 34. The coefficient of friction of the hinge 34 is provided such that the pressure fluctuation is suitably reduced.

Fig. 5 zeigt in schematischer Schnittansicht eine Einrichtung 14 zum Reduzieren von Druckschwankungen gemƤƟ einem noch weiteren AusfĆ¼hrungsbeispiel. Fig. 5 shows a schematic sectional view of a device 14 for reducing pressure fluctuations according to yet another embodiment.

Bei der Einrichtung 14 gemƤƟ Fig. 5 ist im Unterschied zu der Einrichtung 14 gemƤƟ Fig. 3 die Austrittsƶffnung 23 von einem porƶsen Material 35 verschlossen. Bei dem porƶsen Material 35 kann es sich beispielsweise um eine porƶse Keramik oder einen porƶsen Kunststoff handeln. Das Material 35 weist demnach eine Vielzahl von nicht dargestellten Poren auf, welche der PrimƤrluftstrom 13 auf seinem Weg hin zum Brenner 5 durchdringen muss. Die Poren sind dabei derart dimensioniert, dass Druckschwankungen in dem Innenraum 4 nur stark abgepuffert an den Brenner 5 weitergegeben werden.In the device 14 according to Fig. 5 is unlike the device 14 according to Fig. 3 the outlet opening 23 is closed by a porous material 35. The porous material 35 may be, for example, a porous ceramic or a porous plastic. The material 35 accordingly has a plurality of pores, not shown, which penetrate the primary air stream 13 on its way to the burner 5 got to. The pores are dimensioned such that pressure fluctuations in the interior 4 are only greatly buffered passed to the burner 5.

Obwohl die vorliegende Erfindung anhand von AusfĆ¼hrungsbeispielen beschrieben wurde, ist sie vielfƤltig modifizierbar.Although the present invention has been described with reference to embodiments, it is variously modifiable.
