Definitions

  • the present invention relates to a combination appliance with a cooktop and fume extraction device.
  • downdraft fans In kitchens, it is known to use so-called downdraft fans instead of extractor hoods, which are arranged above a hob, for example on the room wall or ceiling, in order to suck off fumes and vapors that arise during cooking.
  • a downdraft ventilation In the DE 10 2013 007 722 A1 such a downdraft ventilation is described, for example.
  • a cooking steam inlet opening located in the hob level is connected to a vacuum source via an exhaust air duct system.
  • the downdraft ventilation is provided as a separate device between two hobs or next to a hob.
  • a disadvantage of this downdraft ventilation is the large amount of space that is required due to the exhaust air duct system to be provided.
  • the distance between the inlet opening and the vacuum source is also large here, so that increased demands are placed on the vacuum source, which in particular can be a suction fan.
  • a hob with central suction of cooking vapors downwards In this hob, one or more recesses are made in the area around the geometric centroid.
  • Devices for extracting cooking vapors are provided below the hob.
  • the devices for extracting kitchen fumes are preferably radial fans that are attached to the underside of a hob housing and are sucked upwards via the air from cooking vapor extraction chambers located below.
  • a disadvantage of this arrangement is that the cut-out in the center of the surface is not close enough to all the cooking devices and can also be a hindrance during the cooking process.
  • an induction hob which has a heat management system.
  • the internal electronic components in the cooktop have an improved flow of air.
  • the Cooktop may include a sensor that scans the cooktop for items placed on it and operates a fan in a blower by feedback to the device.
  • a heat cooking device with a cooling device and a suction device for sucking off oil vapors or the like generated during cooking is known.
  • the suction device includes a fan which is arranged below the cooking insert.
  • the upper suction opening, via which air is sucked into the suction device, is formed in a cover plate offset to the rear of the cooking insert.
  • a disadvantage of these devices, which relate to heat management, is that reliable extraction of fumes and vapors cannot be guaranteed.
  • the object of the present invention is therefore to create a combination appliance in which vapors and vapors can be extracted from the space above a hob in a simple and reliable manner with a preferably simple structure of the combination appliance.
  • the invention is based on the knowledge that this object can be achieved by the at least one cutout being made in a cover plate of the hob in a combination appliance and extending along at least one edge region of the hob.
  • the combination appliance according to the invention comprises a hob and an extractor hood.
  • these two components of the combination device are designed as an assembly unit, that is to say a structural unit.
  • This means that the two components of the combination device are attached directly or indirectly to each other and as an assembly unit, for example in a Worktop can be introduced.
  • the combination device thus represents an assembled or pre-assembled unit, or a pre-assembled unit.
  • the hob comprises a heating element and a cover plate.
  • the cover plate covers one heating element from above.
  • the size of the heating element, or its effective radius, determines the size of the cooking zone or hotplate in the hob on which pots or other cooking vessels can be placed for heating.
  • the heating element can be an induction module, for example. If the heating element is an induction module, it can consist of several heating units which together define a cooking zone. Heating units that are activated together in order to heat a container for the food to be cooked are also referred to as cooking zones.
  • the extractor device comprises at least one fan and preferably additionally an air duct for guiding the air out of the combination device after it has exited the fan.
  • At least one recess is made in the hob.
  • the recess is made in the top plate of the hob.
  • the hob it is possible for the hob to have, in addition to the cover plate, a housing in which the heating elements are accommodated.
  • the extractor device is arranged below the hob.
  • An extractor device is referred to as being arranged below the cooktop, in which at least part of the fan of the extractor device is located further down than the lowest point of the cooktop.
  • the extractor device is arranged below the top of the hob, that is to say below the cover plate.
  • the fan of the fume extraction device can be arranged, for example, between two heating elements of the cooktop or can be offset completely to the bottom of the heating elements.
  • Directional information such as above and below relates to the combination device in the assembled and mounted state, that is to say in the state in which it is placed, for example, in a horizontal worktop.
  • the air from the space above the hob and in particular vapors and vapors that arise during cooking are sucked off according to the invention via the at least one recess of the hob.
  • the recess in the hob is the intake opening of the combination device.
  • the opening through which air enters the interior of the combination device is referred to as the suction opening of the combination device. Since the recess in the hob, which is preferably in the plane of the top of the hob, in particular the top plate of the hob, represents the suction opening, it is not necessary to provide further line elements, such as channels or pipes, which extend upwards relative to the hob.
  • the structure of the combination device and its handling are thus simplified. In particular, pots or other cooking vessels can be moved essentially freely on the hob.
  • the suction opening represents a recess in the hob of the combination appliance, instead of providing the suction opening as part of a separate appliance, as is the case in the prior art.
  • the extractor device of the combination device has at least one fan.
  • the fan which can also be referred to as a fan or suction fan, preferably includes a fan housing, which is designed, for example, as a spiral housing or worm housing and is also referred to as a fan housing.
  • a fan wheel is accommodated in the fan housing and is driven by a motor which is also accommodated in the fan housing.
  • the fan housing has an air inlet opening through which the air that has been sucked in can reach the fan wheel.
  • the fan housing has an air outlet opening, via which air can be discharged radially into a discharge duct or directly from the combination device.
  • the air inlet opening is preferably in the area of the axis of the fan wheel.
  • the combination appliance is characterized in that at least one recess is made in the hob, which is in the edge area of the cover plate of the hob.
  • the edge area of the cover plate, in which at least one recess is provided can be, for example, the lateral edge areas of the generally rectangular hob. Alternatively or additionally, the edge area in which at least one recess is provided can also be the rear edge area of the hob.
  • the recess can have a round or square shape.
  • the cutout or cutouts represent oblong, rectangular openings. With this design of the cutout(s) as oblong slots, sufficient suction of vapors and vapors from the space above the cooktop can be ensured, since the cutout extends across the depth or width of the cooktop and thus be in the vicinity of cooking vessels placed on the cooking zone(s) formed by the heating element(s).
  • the cutout is made in the hob in such a way that it lies within the surface of the cover plate.
  • the recess can extend to the edge of the cover plate or be arranged in the cover plate at a distance from the edge.
  • a number of advantages can be achieved by providing a combination appliance according to the invention, in which a hob and an extractor device are integrated in one appliance, and at least one recess is also made in the hob, which is located in the edge area of the hob.
  • the hob and vapor extraction device can be installed as a unit in a worktop or other surface and, if necessary, removed.
  • the integration of the two components in a combination device reduces the overall height required, since the parts of the components can be provided in the combination device in an aligned manner with respect to one another.
  • the orientation of the components in particular the orientation of the blower to the at least one cutout in a combination device, is predetermined, thus simplifying assembly and installation.
  • the area of the hob can be adjacent to or between the cutouts form a continuous surface on which cooking vessels, such as pots and pans, can be moved freely.
  • the heating element of the hob can also be designed to be continuous, so that the entire area between the recesses can serve as a cooking zone in which several cooking zones can be flexibly formed.
  • the cover plate covers the heating element and extends beyond at least one edge of the heating element, and the at least one recess is made in the overhang of the cover plate formed in this way, adjacent to the heating element.
  • the overhang over the heating element can be formed at the back or the side edges of the cover plate. It would also be possible to provide the overhang on the front side of the cover plate. However, this would make the combination appliance more difficult to use, since the user would have to reach over the recess formed in the front edge of the cover plate in order to be able to access the cooking vessels on the hob. Since the at least one cutout in the edge area of the cover plate is or are made in a projection that protrudes beyond the heating element and is adjacent to the heating element, the area under the cutout is free of heating elements and the ventilation routing from the cutout to the fan is simplified. In addition, the surface of the hob in which the heating element is provided is not interrupted by a recess, which simplifies the construction of the combination appliance.
  • the arrangement of the recess(es) adjacent to the heating element ensures reliable extraction of fumes and vapors, since these can be sucked into the recess(es) in the vicinity of their point of origin.
  • the shape of the recess can also be freely selected. For example, elongated slots can be made in the cover plate, the length of which extends in the depth direction of the cover plate or in the width direction of the cover plate.

Description

Die vorliegende Erfindung betrifft ein KombinationsgerƤt mit Kochfeld und Du nstabzugsvorrichtung.The present invention relates to a combination appliance with a cooktop and fume extraction device.

In KĆ¼chen ist es bekannt, statt Dunstabzugshauben, die Ć¼ber einem Kochfeld beispielsweise an der Raumwand oder Decke angeordnet werden, sogenannte MuldenlĆ¼fter zu verwenden, um DĆ¼nste und Wrasen, die beim Kochen entstehen, abzusaugen. In der DE 10 2013 007 722 A1 ist beispielsweise eine solche MuldenlĆ¼ftung beschrieben. Hierbei wird eine in der Kochfeldebene gelegene Kochdampf-Eintrittsƶffnung Ć¼ber ein Abluftkanalsystem mit einer Unterdruckquelle verbunden. Die MuldenlĆ¼ftung wird hierbei als separates GerƤt zwischen zwei Kochfeldern oder neben einem Kochfeld vorgesehen. Ein Nachteil dieser MuldenlĆ¼ftung besteht in dem groƟen Platzbedarf, der aufgrund des vorzusehenden Abluftkanalsystems besteht. Zudem ist hierbei auch der Abstand zwischen der Eintrittsƶffnung und der Unterdruckquelle groƟ, so dass gesteigerte Anforderungen an die Unterdruckquelle, die insbesondere ein SauggeblƤse darstellen kann, gestellt werden.In kitchens, it is known to use so-called downdraft fans instead of extractor hoods, which are arranged above a hob, for example on the room wall or ceiling, in order to suck off fumes and vapors that arise during cooking. In the DE 10 2013 007 722 A1 such a downdraft ventilation is described, for example. In this case, a cooking steam inlet opening located in the hob level is connected to a vacuum source via an exhaust air duct system. The downdraft ventilation is provided as a separate device between two hobs or next to a hob. A disadvantage of this downdraft ventilation is the large amount of space that is required due to the exhaust air duct system to be provided. In addition, the distance between the inlet opening and the vacuum source is also large here, so that increased demands are placed on the vacuum source, which in particular can be a suction fan.

Weiterhin ist aus der WO 2012/146237 A1 ein Kochfeld mit zentraler Absaugung von KochdĆ¼nsten nach unten bekannt. Bei diesem Kochfeld wird einer oder werden mehrere Aussparungen im Bereich um den geometrischen FlƤchenschwerpunkt eingebracht. Unterhalb des Kochfeldes sind Vorrichtungen zum Abzug von KĆ¼chendĆ¼nsten vorgesehen. Die Vorrichtungen zum Abzug von KĆ¼chendĆ¼nsten stellen vorzugsweise RadiallĆ¼fter dar, die an der Unterseite eines KochfeldgehƤuses befestigt sind und Ć¼ber die Luft aus unten liegenden Kochdunstabsaugkammern nach oben abgesaugt werden.Furthermore, from the WO 2012/146237 A1 a hob with central suction of cooking vapors downwards. In this hob, one or more recesses are made in the area around the geometric centroid. Devices for extracting cooking vapors are provided below the hob. The devices for extracting kitchen fumes are preferably radial fans that are attached to the underside of a hob housing and are sucked upwards via the air from cooking vapor extraction chambers located below.

Ein Nachteil dieser Anordnung besteht darin, dass die Aussparung in der FlƤchenmitte nicht nahe genug an allen GargutgerƤten liegt und zudem wƤhrend des Kochvorgangs hinderlich sein kann.A disadvantage of this arrangement is that the cut-out in the center of the surface is not close enough to all the cooking devices and can also be a hindrance during the cooking process.

Zudem ist aus der US 2010/0163549 A1 ein Induktionskochfeld bekannt, das ein WƤrmemanagementsystem aufweist. Insbesondere werden die internen elektronischen Komponenten in dem Kochfeld von einem verbesserten Luftstrom angestrƶmt. Das Kochfeld kann einen Sensor umfassen, der das Kochfeld nach darauf platzierten GegenstƤnden abscannt und einen Ventilator in einem GeblƤse durch RĆ¼ckmeldung an die Vorrichtung betƤtigt wird.In addition, from the U.S. 2010/0163549 A1 an induction hob is known which has a heat management system. In particular, the internal electronic components in the cooktop have an improved flow of air. The Cooktop may include a sensor that scans the cooktop for items placed on it and operates a fan in a blower by feedback to the device.

Zudem ist aus der DE 37 41 721 A1 eine WƤrme-Kochvorrichtung mit einer KĆ¼hleinrichtung sowie einer Absaugeinrichtung zum Absaugen von ƖldƤmpfen oder dergleichen, die beim Kochen entstehen, bekannt. Die Absaugvorrichtung umfasst einen LĆ¼fter, der unterhalb des Kocheinsatzes angeordnet ist. Die obere Saugƶffnung, Ć¼ber die Luft in die Absaugeinrichtung eingesaugt wird, ist zu dem Kocheinsatz nach hinten versetzt in einer Deckplatte ausgebildet.In addition, from the DE 37 41 721 A1 a heat cooking device with a cooling device and a suction device for sucking off oil vapors or the like generated during cooking is known. The suction device includes a fan which is arranged below the cooking insert. The upper suction opening, via which air is sucked into the suction device, is formed in a cover plate offset to the rear of the cooking insert.

Ein Nachteil dieser Vorrichtungen, die das WƤrmemanagement betreffen, besteht darin, dass ein zuverlƤssiges Absaugen von DĆ¼nsten und Wrasen nicht gewƤhrleistet werden kann.A disadvantage of these devices, which relate to heat management, is that reliable extraction of fumes and vapors cannot be guaranteed.

Aufgabe der vorliegenden Erfindung ist es somit, ein KombinationsgerƤt zu schaffen, bei dem auf einfache und zuverlƤssige Weise bei einem vorzugsweise einfachen Aufbau des KombinationsgerƤtes DĆ¼nste und Wrasen von dem Raum Ć¼ber einem Kochfeld abgesaugt werden kƶnnen.The object of the present invention is therefore to create a combination appliance in which vapors and vapors can be extracted from the space above a hob in a simple and reliable manner with a preferably simple structure of the combination appliance.

Der Erfindung liegt die Erkenntnis zugrunde, dass diese Aufgabe gelƶst werden kann, indem in einem KombinationsgerƤt die mindestens eine Aussparung in eine Deckplatte des Kochfeldes eingebracht wird und sich entlang mindestens eines Randbereiches des Kochfeldes erstreckt.The invention is based on the knowledge that this object can be achieved by the at least one cutout being made in a cover plate of the hob in a combination appliance and extending along at least one edge region of the hob.

ErfindungsgemƤƟ wird die Aufgabe daher gelƶst durch ein KombinationsgerƤt mit den Merkmalen des Anspruchs 1.According to the invention, the object is therefore achieved by a combination device with the features of claim 1.

Das erfindungsgemƤƟe KombinationsgerƤt umfasst ein Kochfeld und eine Dunstabzugsvorrichtung. Insbesondere sind diese beiden Komponenten des KombinationsgerƤtes als Montageeinheit, das heiƟt bauliche Einheit, ausgestaltet. Dies bedeutet, dass die beiden Komponenten des KombinationsgerƤtes mittelbar oder unmittelbar aneinander befestigt sind und als eine Montageeinheit beispielsweise in einer Arbeitsplatte eingebracht werden kƶnnen. Das KombinationsgerƤt stellt somit eine zusammengebaute oder vormontierte Einheit, oder eine vormontierbare Einheit dar.The combination appliance according to the invention comprises a hob and an extractor hood. In particular, these two components of the combination device are designed as an assembly unit, that is to say a structural unit. This means that the two components of the combination device are attached directly or indirectly to each other and as an assembly unit, for example in a Worktop can be introduced. The combination device thus represents an assembled or pre-assembled unit, or a pre-assembled unit.

Das Kochfeld umfasst erfindungsgemƤƟ ein Heizelement und eine Deckplatte. Die Deckplatte deckt das eine Heizelement von oben ab. Die GrĆ¶ĆŸe des Heizelementes oder dessen Wirkradius, bestimmt die GrĆ¶ĆŸe der Kochzone oder Kochstelle in dem Kochfeld auf den Tƶpfe oder andere KochgefƤƟe zum Erhitzen aufgestellt werden kƶnnen. Das Heizelement kann beispielsweise ein Induktionsmodul darstellen. Ist das Heizelement ein Induktionsmodul, so kann dieses aus mehreren Heizeinheiten bestehen, die gemeinsam eine Kochzone definieren. Heizeinheiten, die gemeinsam aktiviert werden, um ein darauf befindliches GargutgefƤƟ zu erhitzen werden auch als Garzone bezeichnet.According to the invention, the hob comprises a heating element and a cover plate. The cover plate covers one heating element from above. The size of the heating element, or its effective radius, determines the size of the cooking zone or hotplate in the hob on which pots or other cooking vessels can be placed for heating. The heating element can be an induction module, for example. If the heating element is an induction module, it can consist of several heating units which together define a cooking zone. Heating units that are activated together in order to heat a container for the food to be cooked are also referred to as cooking zones.

Die Dunstabzugsvorrichtung umfasst erfindungsgemƤƟ mindestens ein GeblƤse sowie vorzugsweise zusƤtzlich eine LuftfĆ¼hrung zur Leitung der Luft nach dem Austritt aus dem GeblƤse aus dem KombinationsgerƤt heraus.According to the invention, the extractor device comprises at least one fan and preferably additionally an air duct for guiding the air out of the combination device after it has exited the fan.

ErfindungsgemƤƟ ist in dem Kochfeld mindestens eine Aussparung eingebracht. Die Aussparung ist in die Deckplatte des Kochfeldes eingebracht. Zudem ist es mƶglich, dass das Kochfeld auƟer der Deckplatte ein GehƤuse aufweist, in dem die Heizelemente aufgenommen sind.According to the invention, at least one recess is made in the hob. The recess is made in the top plate of the hob. In addition, it is possible for the hob to have, in addition to the cover plate, a housing in which the heating elements are accommodated.

Die Dunstabzugsvorrichtung ist erfindungsgemƤƟ unterhalb des Kochfeldes angeordnet. Als unterhalb des Kochfeldes angeordnet wird eine Dunstabzugsvorrichtung bezeichnet, bei der zumindest ein Teil des GeblƤses der Dunstabzugsvorrichtung weiter unten liegt, als die tiefste Stelle des Kochfeldes. In jedem Fall ist die Dunstabzugsvorrichtung aber unterhalb der Oberseite des Kochfeldes, das heiƟt unterhalb der Deckplatte angeordnet. Das GeblƤse der Dunstabzugsvorrichtung kann beispielsweise zwischen zwei Heizelementen des Kochfeldes angeordnet sein oder vollstƤndig zu den Heizelementen nach unten versetzt liegen.According to the invention, the extractor device is arranged below the hob. An extractor device is referred to as being arranged below the cooktop, in which at least part of the fan of the extractor device is located further down than the lowest point of the cooktop. In any case, however, the extractor device is arranged below the top of the hob, that is to say below the cover plate. The fan of the fume extraction device can be arranged, for example, between two heating elements of the cooktop or can be offset completely to the bottom of the heating elements.

Richtungsangaben, wie oben und unten beziehen sich auf das KombinationsgerƤt im zusammengebauten und montierten Zustand, das heiƟt in dem Zustand, in dem dieses beispielsweise in einer horizontalen Arbeitsplatte eingebracht ist.Directional information such as above and below relates to the combination device in the assembled and mounted state, that is to say in the state in which it is placed, for example, in a horizontal worktop.

Die Luft aus dem Raum oberhalb des Kochfeldes und insbesondere DĆ¼nste und Wrasen, die beim Kochen entstehen, werden erfindungsgemƤƟ Ć¼ber die mindestens eine Aussparung des Kochfeldes abgesaugt. Die Aussparung in dem Kochfeld ist dabei die Ansaugƶffnung des KombinationsgerƤtes. Als Ansaugƶffnung des KombinationsgerƤtes wird hierbei die Ɩffnung bezeichnet, Ć¼ber die Luft in das Innere des KombinationsgerƤtes eintritt. Indem die Aussparung des Kochfeldes, die vorzugsweise in der Ebene der Oberseite des Kochfeldes, insbesondere der Deckplatte des Kochfeldes liegt, die Ansaugƶffnung darstellt, ist es nicht erforderlich weitere Leitungselemente, wie beispielsweise KanƤle oder Rohre vorzusehen, die sich gegenĆ¼ber dem Kochfeld nach oben erstrecken. Somit werden der Aufbau des KombinationsgerƤtes und dessen Handhabung vereinfacht. Insbesondere kƶnnen Tƶpfe oder andere GargefƤƟe im Wesentlichen frei auf dem Kochfeld verschoben werden. Allerdings ist es erfindungsgemƤƟ mƶglich, dass in der Ansaugƶffnung Elemente, wie beispielsweise eine Filtereinheit oder Abdeckung vorgesehen sind, die gegebenenfalls Ć¼ber die Oberseite des Kochfeldes geringfĆ¼gig hinausragen. Zudem ist der Aufbau des KombinationsgerƤtes dadurch vereinfacht, dass die Ansaugƶffnung eine Aussparung in dem Kochfeld des KombinationsgerƤtes darstellt, statt, wie im Stand der Technik die Ansaugƶffnung als Teil eines separaten GerƤtes vorzusehen.The air from the space above the hob and in particular vapors and vapors that arise during cooking are sucked off according to the invention via the at least one recess of the hob. The recess in the hob is the intake opening of the combination device. The opening through which air enters the interior of the combination device is referred to as the suction opening of the combination device. Since the recess in the hob, which is preferably in the plane of the top of the hob, in particular the top plate of the hob, represents the suction opening, it is not necessary to provide further line elements, such as channels or pipes, which extend upwards relative to the hob. The structure of the combination device and its handling are thus simplified. In particular, pots or other cooking vessels can be moved essentially freely on the hob. However, it is possible according to the invention for elements such as a filter unit or cover to be provided in the intake opening, which may protrude slightly beyond the top of the hob. In addition, the structure of the combination appliance is simplified in that the suction opening represents a recess in the hob of the combination appliance, instead of providing the suction opening as part of a separate appliance, as is the case in the prior art.

ErfindungsgemƤƟ weist die Dunstabzugsvorrichtung des KombinationsgerƤtes mindestens ein GeblƤse auf. Das GeblƤse, das auch als LĆ¼fter oder SauggeblƤse bezeichnet werden kann, umfasst vorzugsweise ein GeblƤsegehƤuse, das beispielsweise als SpiralgehƤuse oder SchneckengehƤuse ausgestaltet ist und auch als LĆ¼ftergehƤuse bezeichnet wird. In dem GeblƤsegehƤuse ist ein LĆ¼fterrad aufgenommen, das Ć¼ber einen ebenfalls in dem GeblƤsegehƤuse aufgenommenen Motor angetrieben wird. Das GeblƤsegehƤuse weist eine Lufteintrittsƶffnung auf, Ć¼ber die angesaugte Luft zu dem LĆ¼fterrad gelangen kann. Weiterhin weist das LĆ¼ftergehƤuse eine Luftaustrittsƶffnung auf, Ć¼ber die Luft radial in einen Ableitungskanal oder unmittelbar aus dem KombinationsgerƤt ausgelassen werden kann. Bei einem GeblƤse, das ein RadialgeblƤse darstellt, liegt die Lufteintrittsƶffnung vorzugsweise im Bereich der Achse des LĆ¼fterrades.According to the invention, the extractor device of the combination device has at least one fan. The fan, which can also be referred to as a fan or suction fan, preferably includes a fan housing, which is designed, for example, as a spiral housing or worm housing and is also referred to as a fan housing. A fan wheel is accommodated in the fan housing and is driven by a motor which is also accommodated in the fan housing. The fan housing has an air inlet opening through which the air that has been sucked in can reach the fan wheel. Furthermore, the fan housing has an air outlet opening, via which air can be discharged radially into a discharge duct or directly from the combination device. In a fan that is a radial fan, the air inlet opening is preferably in the area of the axis of the fan wheel.

Das KombinationsgerƤt ist dadurch gekennzeichnet, dass in das Kochfeld mindestens eine Aussparung eingebracht ist, die im Randbereich der Deckplatte des Kochfeldes liegt.The combination appliance is characterized in that at least one recess is made in the hob, which is in the edge area of the cover plate of the hob.

Der Randbereich der Deckplatte, in dem mindestens eine Aussparung vorgesehen ist, kƶnnen beispielsweise die seitlichen Randbereiche des in der Regel rechteckigen Kochfeldes sein. Alternativ oder zusƤtzlich kann der Randbereich, in dem mindestens eine Aussparung vorgesehen ist, auch der rĆ¼ckwƤrtige Randbereich des Kochfeldes sein.The edge area of the cover plate, in which at least one recess is provided, can be, for example, the lateral edge areas of the generally rectangular hob. Alternatively or additionally, the edge area in which at least one recess is provided can also be the rear edge area of the hob.

Die Aussparung kann erfindungsgemƤƟ eine runde oder viereckige Form aufweisen. Vorzugsweise stellt die Aussparung beziehungsweise stellen die Aussparungen lƤngliche, rechteckige Ɩffnungen dar. Bei dieser Ausgestaltung der Aussparung(en) als lƤngliche Schlitze kann eine ausreichende Absaugung von DĆ¼nsten und Wrasen aus dem Raum oberhalb des Kochfeldes gewƤhrleistet, da sich die Aussparung Ć¼ber die Tiefe oder Breite des Kochfeldes erstrecken kann und somit in der NƤhe von GargefƤƟen liegen, die auf der durch das / die Heizelemente gebildete Kochzone(n), aufgesetzt sind.According to the invention, the recess can have a round or square shape. Preferably, the cutout or cutouts represent oblong, rectangular openings. With this design of the cutout(s) as oblong slots, sufficient suction of vapors and vapors from the space above the cooktop can be ensured, since the cutout extends across the depth or width of the cooktop and thus be in the vicinity of cooking vessels placed on the cooking zone(s) formed by the heating element(s).

ErfindungsgemƤƟ ist die Aussparung so in das Kochfeld eingebracht, dass diese innerhalb der FlƤche der Deckplatte liegt. Hierbei kann die Aussparung sich bis an den Rand der Deckplatte erstrecken oder zu dem Rand beabstandet in der Deckplatte angeordnet sein.According to the invention, the cutout is made in the hob in such a way that it lies within the surface of the cover plate. In this case, the recess can extend to the edge of the cover plate or be arranged in the cover plate at a distance from the edge.

Indem erfindungsgemƤƟ ein KombinationsgerƤt bereitgestellt wird, bei dem ein Kochfeld und eine Dunstabzugsvorrichtung in einem GerƤt integriert sind, und zudem mindestens eine Aussparung in das Kochfeld eingebracht ist, die im Randbereich des Kochfeldes liegt, kann eine Reihe von Vorteilen erzielt werden.A number of advantages can be achieved by providing a combination appliance according to the invention, in which a hob and an extractor device are integrated in one appliance, and at least one recess is also made in the hob, which is located in the edge area of the hob.

Durch das Integrieren der Dunstabzugsvorrichtung mit dem Kochfeld in einem GerƤt, ist die Montage vereinfacht. Insbesondere kƶnnen Kochfeld und Dunstabzugsvorrichtung als eine Einheit in eine Arbeitsplatte oder andere OberflƤche eingebracht und gegebenenfalls entnommen werden. Weiterhin ist durch die Integration der beiden Komponenten in einem KombinationsgerƤt die erforderliche Bauhƶhe reduziert, da die Bauteile der Komponenten zueinander ausgerichtet in dem KombinationsgerƤt vorgesehen sein kƶnnen. Zudem ist die Ausrichtung der Komponenten, insbesondere die Ausrichtung des GeblƤses zu der mindestens einen Aussparung bei einem KombinationsgerƤt vorgegeben und so der Zusammenbau und die Montage vereinfacht. SchlieƟlich kann, da erfindungsgemƤƟ die Aussparung(en) in dem Kochfeld im Randbereich gebildet ist beziehungsweise sind, der Bereich des Kochfeldes benachbart zu beziehungsweise zwischen den Aussparungen eine durchgehende FlƤche bilden, auf der GargefƤƟe, wie Tƶpfe und Pfannen frei verschoben werden kƶnnen. Auch das Heizelement des Kochfeldes kann erfindungsgemƤƟ durchgehend ausgestaltet sein, so dass der gesamte Bereich zwischen den Aussparungen als eine Kochzone dienen kann, in der mehrere Garzonen flexibel gebildet werden kƶnnen.By integrating the extractor device with the hob in one device, installation is simplified. In particular, the hob and vapor extraction device can be installed as a unit in a worktop or other surface and, if necessary, removed. Furthermore, the integration of the two components in a combination device reduces the overall height required, since the parts of the components can be provided in the combination device in an aligned manner with respect to one another. In addition, the orientation of the components, in particular the orientation of the blower to the at least one cutout in a combination device, is predetermined, thus simplifying assembly and installation. Finally, since according to the invention the cutout(s) is/are formed in the hob in the edge area, the area of the hob can be adjacent to or between the cutouts form a continuous surface on which cooking vessels, such as pots and pans, can be moved freely. According to the invention, the heating element of the hob can also be designed to be continuous, so that the entire area between the recesses can serve as a cooking zone in which several cooking zones can be flexibly formed.

GemƤƟ einer AusfĆ¼hrungsform deckt die Deckplatte das Heizelement ab und erstreckt sich Ć¼ber zumindest einen Rand des Heizelementes hinaus und die mindestens eine Aussparung ist in dem so gebildeten Ɯberstand der Deckplatte benachbart zu dem Heizelement eingebracht.According to one embodiment, the cover plate covers the heating element and extends beyond at least one edge of the heating element, and the at least one recess is made in the overhang of the cover plate formed in this way, adjacent to the heating element.

Der Ɯberstand Ć¼ber das Heizelement kann an der RĆ¼ckseite oder den SeitenrƤndern der Deckplatte gebildet sein. Es wƤre auch mƶglich den Ɯberstand an der Vorderseite der Deckplatte vorzusehen. Hierbei wĆ¼rde allerdings die Benutzung des KombinationsgerƤtes erschwert, da der Benutzer Ć¼ber die in dem vorderen Rand der Deckplatte gebildete Aussparung hinĆ¼ber greifen mĆ¼sste, um auf die GargefƤƟe auf dem Kochfeld zugreifen zu kƶnnen. Indem die mindestens eine Aussparung im Randbereich der Deckplatte in einem Ć¼ber das Heizelement herausragenden Ɯberstand eingebracht ist beziehungsweise sind und zu dem Heizelement benachbart ist, ist der Bereich unter der Aussparung frei von Heizelementen und die LĆ¼ftfĆ¼hrung von der Aussparung zu dem GeblƤse wird vereinfacht. Zudem ist die FlƤche des Kochfeldes, in der das Heizelement vorgesehen ist, nicht durch eine Aussparung unterbrochen, wodurch sich der Aufbau des KombinationsgerƤtes vereinfacht. Zudem ist durch die Anordnung der Aussparung(en) benachbart zu dem Heizelement ein zuverlƤssiges Absaugen von DĆ¼nsten und Wrasen gewƤhrleistet, da diese in der NƤhe ihres Entstehungsortes in die Aussparung(en) eingesaugt werden kƶnnen. SchlieƟlich kann in dem Ɯberstand der Deckplatte, in dem keine Heizelemente vorgesehen sind, die Form der Aussparung auch frei gewƤhlt werden. Beispielsweise kƶnnen lƤngliche Schlitze in die Deckplatte eingebracht werden, deren LƤnge sich in Tiefenrichtung der Deckplatte oder in Breitenrichtung der Deckplatte erstrecken. Die LƤnge der Schlitze kann hierbei so groƟ gewƤhlt werden, dass die LƤngsenden der Schlitze in einem geringen Abstand zum Rand der Deckplatte liegen, das heiƟt, die Schlitze in einem geringen Abstand zum Rand der Deckplatte enden und sich somit im Wesentlichen Ć¼ber die gesamte Tiefe oder Breite der Deckplatte erstrecken.The overhang over the heating element can be formed at the back or the side edges of the cover plate. It would also be possible to provide the overhang on the front side of the cover plate. However, this would make the combination appliance more difficult to use, since the user would have to reach over the recess formed in the front edge of the cover plate in order to be able to access the cooking vessels on the hob. Since the at least one cutout in the edge area of the cover plate is or are made in a projection that protrudes beyond the heating element and is adjacent to the heating element, the area under the cutout is free of heating elements and the ventilation routing from the cutout to the fan is simplified. In addition, the surface of the hob in which the heating element is provided is not interrupted by a recess, which simplifies the construction of the combination appliance. In addition, the arrangement of the recess(es) adjacent to the heating element ensures reliable extraction of fumes and vapors, since these can be sucked into the recess(es) in the vicinity of their point of origin. Finally, in the overhang of the cover plate, in which no heating elements are provided, the shape of the recess can also be freely selected. For example, elongated slots can be made in the cover plate, the length of which extends in the depth direction of the cover plate or in the width direction of the cover plate. The length of the slots can be chosen so large that the longitudinal ends of the slots are at a small distance from the edge of the cover plate, that is, the slots end at a small distance from the edge of the cover plate and thus essentially over the entire depth or Extend width of the top plate.

ErfindungsgemƤƟ weist das Kochfeld ein durchgehendes Heizelement auf, das sich Ć¼ber die FlƤche der Deckplatte erstreckt und die mindestens eine Aussparung ist zu dem Heizelement benachbart in der Deckplatte eingebracht. Als durchgehendes Heizelement wird hierbei ein Heizelement bezeichnet, durch das eine Kochzone gebildet wird, die eine durchgehende FlƤche bildet. Das Heizelement besteht aus mehreren Heizeinheiten. Die Heizeinheiten des Heizelementes kƶnnen hierbei in AbhƤngigkeit von zumindest einem auf dem Kochfeld platzierten GargutbehƤlter zu einer Garzone oder Garbereich kombiniert werden. Insbesondere kƶnnen die Heizeinheiten eines Heizelementes dann aktiviert werden, wenn erkannt wird, dass auf diesen ein GargutbehƤlter platziert ist. Bei dem Kochfeld, bei dem das Heizelement somit eine durchgehende Kochzone bildet, die in AbhƤngigkeit der Position eines GargutbehƤlters in dem Bereich des GargutbehƤlters aktiviert wird, kann die gesamte Kochzone flexibel verwendet werden. Da erfindungsgemƤƟ die Aussparung zum Ansaugen von Luft im Randbereich des Kochfeldes und somit auƟerhalb der FlƤche des Heizelementes liegen, wird das Heizelement nicht unterbrochen und es kƶnnen GargutbehƤlter somit beispielsweise auch auf der FlƤchenmitte des Kochfeldes platziert und dort erwƤrmt werden. Bei einer in der FlƤchenmitte des Kochfeldes vorgesehenen Aussparung wƤre eine solche ErwƤrmung nicht mƶglich.According to the invention, the hob has a continuous heating element that extends over the surface of the cover plate and the at least one recess is made in the cover plate adjacent to the heating element. A continuous heating element is a heating element that forms a cooking zone that forms a continuous surface. The heating element consists of several heating units. The heating units of the heating element can be combined to form a cooking zone or cooking area depending on at least one cooking product container placed on the hob. In particular, the heating units of a heating element can be activated when it is recognized that a cooking product container is placed on them. The entire cooking zone can be used flexibly in the hob, in which the heating element thus forms a continuous cooking zone that is activated depending on the position of a cooking product container in the region of the cooking product container. Since, according to the invention, the recess for sucking in air is in the edge area of the hob and thus outside the surface of the heating element, the heating element is not interrupted and containers for cooking can thus also be placed in the middle of the surface of the hob and heated there. Such heating would not be possible with a recess provided in the center of the hob surface.

GemƤƟ einer bevorzugten AusfĆ¼hrungsform sind in dem Kochfeld zwei Aussparungen vorgesehen, die sich in den beiden seitlichen Randbereichen des Kochfeldes in Tiefenrichtung des Kochfeldes erstrecken. Als Tiefenrichtung wird hierbei die Richtung zwischen der Vorderseite des Kochfeldes und der RĆ¼ckseite des Kochfeldes bezeichnet. Die Aussparungen stellen vorzugsweise jeweils einen lƤnglichen Spalt dar. Die AusfĆ¼hrungsform, bei der sich die beiden Aussparungen jeweils im seitlichen Randbereich des Kochfeldes in Tiefenrichtung erstrecken, weist den Vorteil auf, dass beispielsweise bei einem Kochfeld mit vier Kochzonen, die als zwei vordere und zwei hintere Kochzonen ausgestaltet sind, an jeder Kochzone zumindest ein Teil einer der Aussparungen entlang lƤuft. Somit kann ein zuverlƤssiges Absaugen von DĆ¼nsten und Wrasen gewƤhrleistet werden. Zudem ist der mittlere Bereich des Kochfeldes frei von Aussparungen, so dass beispielsweise auch ein durchgehendes Heizelement eingesetzt werden kann.According to a preferred embodiment, two recesses are provided in the hob, which extend in the two lateral edge regions of the hob in the depth direction of the hob. The direction between the front of the hob and the back of the hob is referred to as the depth direction. The recesses preferably each represent an elongated gap. The embodiment in which the two recesses each extend in the lateral edge area of the hob in the depth direction has the advantage that, for example in the case of a hob with four cooking zones, which are configured as two front and two rear Cooking zones are configured, at least a part of one of the recesses runs along each cooking zone. Thus, a reliable extraction of fumes and vapors can be guaranteed. In addition, the central area of the cooktop has no recesses, so that a continuous heating element can also be used, for example.

Das GeblƤse der Dunstabzugsvorrichtung des KombinationsgerƤtes kann bei dem erfindungsgemƤƟen KombinationsgerƤt an unterschiedlichen Positionen angeordnet sein.The fan of the extractor device of the combination device can be arranged in different positions in the combination device according to the invention.

GemƤƟ einer AusfĆ¼hrungsform ist die mindestens eine Aussparung zu dem mindestens einen GeblƤse horizontal versetzt. Hierbei kann das GeblƤse beispielsweise unter der oder den Heizelementen des Kochfeldes angeordnet sein. Das GeblƤse kann bei dieser AusfĆ¼hrungsform beispielsweise in der FlƤchenmitte des Kochfeldes angeordnet sein. Es ist auch mƶglich, dass die Dunstabzugsvorrichtung mehrere GeblƤse, beispielsweise zwei oder vier GeblƤse umfasst. Zwei GeblƤse kƶnnen dann verteilt in dem KombinationsgerƤt angeordnet sein und beispielsweise in der Mitte der Breitenrichtung des KombinationsgerƤtes unter dem oder den Heizelementen als ein vorderes und ein hinteres GeblƤse angeordnet sein. Sind vier GeblƤse vorgesehen, kƶnnen diese beispielsweise als zwei hintere und zwei vordere GeblƤse rechts und links von der Mitte der Breitenrichtung des KombinationsgerƤtes angeordnet sein.According to one embodiment, the at least one recess is offset horizontally with respect to the at least one fan. In this case, the fan can be arranged, for example, under the heating element or elements of the hob. In this embodiment, the fan can be arranged, for example, in the middle of the surface of the hob. It is also possible for the fume extraction device to include a plurality of fans, for example two or four fans. Two fans can then be distributed in the combination device and arranged, for example, in the middle of the width direction of the combination device under the heating element or elements as a front and a rear fan. If four fans are provided, they can be arranged, for example, as two rear fans and two front fans on the right and left of the center of the width direction of the combination device.

Die AusfĆ¼hrungsform, bei der das oder die GeblƤse zu der oder den Aussparungen horizontal versetzt angeordnet ist beziehungsweise sind, weist den Vorteil auf, dass das direkte Eindringen von Verunreinigungen und insbesondere FlĆ¼ssigkeiten in das GeblƤse Ć¼ber die Aussparung verhindert ist. Zudem kann an der mindestens einen Aussparung eine Abdeckung vorgesehen sein, die zumindest einen Teil der Aussparung abdeckt und dadurch den Eintritt von Verunreinigungen in das Innere minimiert. Die LuftfĆ¼hrung von der Aussparung zu der Lufteintrittsƶffnung des GeblƤses kann bei dieser AusfĆ¼hrungsform durch die AuƟenwƤnde des KombinationsgerƤtes sowie beispielsweise durch das oder die Heizelemente beziehungsweise GehƤusen der Heizelemente erfolgen. Es ist aber auch mƶglich beispielsweise Luftleitelemente in dem KombinationsgerƤt vorzusehen, die zumindest teilweise einen von der Aussparung zu der Lufteintrittsƶffnung des GeblƤses verlaufenden LuftfĆ¼hrungskanal bilden. Die Luftleitelemente kƶnnen beispielsweise Filterhalterungen zum Halten von Filterelementen oder Sammelbereiche zum Sammeln von FlĆ¼ssigkeiten umfassen.The embodiment in which the fan or fans is or are arranged offset horizontally with respect to the recess or recesses has the advantage that contaminants and in particular liquids are prevented from penetrating directly into the fan via the recess. In addition, a cover can be provided on the at least one recess, which covers at least part of the recess and thereby minimizes the entry of contaminants into the interior. In this embodiment, the air can be routed from the recess to the air inlet opening of the fan through the outer walls of the combination device and, for example, through the heating element or elements or housings of the heating elements. However, it is also possible, for example, to provide air guide elements in the combination device, which at least partially form an air duct running from the cutout to the air inlet opening of the fan. The air guiding elements can include, for example, filter holders for holding filter elements or collecting areas for collecting liquids.

GemƤƟ einer weiteren AusfĆ¼hrungsform ist das GeblƤse der Dunstabzugsvorrichtung in vertikaler Draufsicht auf die Aussparung unter der Aussparung angeordnet. Hierbei ist insbesondere die Lufteintrittsƶffnung des GeblƤses unter der Aussparung angeordnet. Auch bei dieser AusfĆ¼hrungsform kƶnnen unter jeder der Aussparungen ein oder mehrere GeblƤse angeordnet sein. Bei lƤnglichen Schlitzen als Aussparungen kƶnnen beispielsweise Ć¼ber die LƤnge des Schlitzes zwei GeblƤse vorgesehen sein. Bei der AusfĆ¼hrungsform, bei der das oder die GeblƤse unter der Aussparung liegen, ist die LuftfĆ¼hrung zwischen der Aussparung und dem GeblƤse vereinfacht. Zum Schutz des GeblƤses vor einem Eintritt von Verunreinigungen und FlĆ¼ssigkeiten Ć¼ber die Aussparung kann bei dieser AusfĆ¼hrungsform eine Filtereinheit und/oder eine Abdeckung vorgesehen werden.According to a further embodiment, the fan of the fume extraction device is arranged below the recess in a vertical top view of the recess. Here, in particular, the air inlet opening of the fan is arranged under the recess. In this embodiment, too, one or more fans can be arranged under each of the recesses. In the case of elongated slits as recesses, two fans can be provided over the length of the slit, for example. In the embodiment in which the blower or fans are below the recess, the Air flow between the recess and the fan simplified. In this embodiment, a filter unit and/or a cover can be provided to protect the fan from contaminants and liquids entering via the recess.

Auch bezĆ¼glich der vertikalen Ausrichtung des GeblƤses ist die vorliegende Erfindung nicht auf eine bestimmte Ausrichtung beschrƤnkt. Vorzugsweise stellt das GeblƤse der Dunstabzugsvorrichtung ein RadialgeblƤse dar. Dieses GeblƤse weist eine Lufteintrittsƶffnung auf, die axial zu dem Motor des GeblƤses versetzt liegt. Die Luft wird aus dem RadialgeblƤse Ć¼ber eine Luftaustrittsƶffnung in radialer Richtung ausgegeben.The present invention is also not limited to a specific orientation with regard to the vertical orientation of the fan. The fan of the extractor device is preferably a radial fan. This fan has an air inlet opening which is offset axially with respect to the motor of the fan. The air is discharged from the radial fan via an air outlet opening in the radial direction.

GemƤƟ einer AusfĆ¼hrungsform ist das RadialgeblƤse unterhalb des Kochfeldes in dem KombinationsgerƤt so angeordnet, dass die Lufteintrittsƶffnung des GeblƤses nach oben gerichtet ist. Bei dieser AusfĆ¼hrungsform ist die Lufteintrittsƶffnung somit dem Kochfeld zugewandt. Bei dieser AusfĆ¼hrungsform kann ein Luftweg zwischen Aussparung und Lufteintrittsƶffnung erzielt werden, in dem die Luft nur geringfĆ¼gig umgelenkt werden muss. Zudem kann das GeblƤse bei dieser Ausrichtung auf dem Boden eines GerƤtegehƤuses des KombinationsgerƤtes befestigt werden und so der Zusammenbau des KombinationsgerƤtes vereinfacht werden. Zudem ist es erfindungsgemƤƟ auch mƶglich das GeblƤse Ć¼ber die gleiche Seite, in der die Lufteintrittsƶffnung vorgesehen ist, in einem Bereich um die Lufteintrittsƶffnung herum, an dem Kochfeld, insbesondere an der Unterseite des Kochfeldes und insbesondere einer Unterseite eines KochfeldgehƤuses, zu befestigen. Auch bei dieser AusfĆ¼hrungsform kann, da die Lufteintrittsƶffnung des GeblƤses dem Kochfeld zugewandt, das heiƟt nach oben gerichtet ist, insbesondere bei einer AusfĆ¼hrungsform, bei der die Lufteintrittsƶffnung unter der mindestens einen Aussparung liegt, der Zusammenbau des GerƤtes weiter vereinfacht werden, da das GeblƤse beispielsweise unter einem oder zwei Heizelementen befestigt werden kann, die benachbart zu oder auf gegenĆ¼berliegenden Seiten der Aussparung liegen.According to one embodiment, the radial fan is arranged below the hob in the combination appliance in such a way that the air inlet opening of the fan is directed upwards. In this embodiment, the air inlet opening thus faces the hob. In this embodiment, an air path can be achieved between the recess and the air inlet opening, in which the air only has to be deflected slightly. In addition, with this orientation, the blower can be fastened to the bottom of a device housing of the combination device, thus simplifying the assembly of the combination device. In addition, it is also possible according to the invention to fasten the blower on the same side in which the air inlet opening is provided, in an area around the air inlet opening, on the hob, in particular on the underside of the hob and in particular an underside of a hob housing. In this embodiment, too, since the air inlet opening of the fan faces the hob, i.e. is directed upwards, particularly in an embodiment in which the air inlet opening is below the at least one recess, the assembly of the device can be further simplified because the fan, for example can be mounted under one or two heating elements lying adjacent to or on opposite sides of the recess.

GemƤƟ einer weiteren AusfĆ¼hrungsform ist das RadialgeblƤse unterhalb des Kochfeldes in dem KombinationsgerƤt so angeordnet, dass die Lufteintrittsƶffnung des GeblƤses nach unten gerichtet ist. Bei dieser AusfĆ¼hrungsform kann das RadialgeblƤse beispielsweise an der Unterseite des Kochfeldes, beispielsweise an der Unterseite eines GehƤuses des oder der Heizelemente befestigt werden. Diese AusfĆ¼hrungsform weist den Vorteil auf, dass ein Eintreten von Verunreinigungen und FlĆ¼ssigkeiten Ć¼ber die Lufteintrittsƶffnung in das GehƤuse ausgeschlossen ist.According to a further embodiment, the radial fan is arranged below the hob in the combination appliance in such a way that the air inlet opening of the fan is directed downwards. In this embodiment, the radial fan can, for example, on the underside of the hob, for example on the underside of a housing or the heating elements. This embodiment has the advantage that contaminants and liquids cannot enter the housing via the air inlet opening.

Es kƶnnen erfindungsgemƤƟ auch mehrere GeblƤse, insbesondere RadialgeblƤse vorgesehen sein, wobei diese jeweils so angeordnet sein kƶnnen, dass die Lufteintrittsƶffnungen von allen GeblƤsen nach unten gerichtet sind, dass die Lufteintrittsƶffnung von allen GeblƤsen nach oben gerichtet sind oder dass die Lufteintrittsƶffnungen von einem oder mehreren GeblƤsen nach oben und die Lufteintrittsƶffnungen der weiteren GeblƤse nach unten gerichtet sind.According to the invention, several fans, in particular radial fans, can also be provided, whereby these can each be arranged in such a way that the air inlet openings of all fans are directed downwards, that the air inlet openings of all fans are directed upwards or that the air inlet openings of one or more fans upwards and the air inlet openings of the other fans are directed downwards.

ErfindungsgemƤƟ weist das KombinationsgerƤt eine Positionserkennungsvorrichtung zum Erkennen der Position eines GargefƤƟes auf dem Kochfeld auf. Die Positionserkennungsvorrichtung ist erfindungsgemƤƟ mit der Dunstabzugsvorrichtung verbunden. Die Positionserkennungsvorrichtung kann in dem Heizelement integriert sein. Insbesondere kann bei einem Heizelement, das ein Induktionsmodul darstellt, die Positionserkennungsvorrichtung in dem Heizelement integriert sein. Es sind aber auch andere Positionserkennungsvorrichtungen, wie beispielsweise optische Positionserkennungsvorrichtungen, erfindungsgemƤƟ eingesetzt werden. ErfindungsgemƤƟ ist eine Positionserkennungsvorrichtung bei einem KombinationsgerƤtes vorgesehen, bei dem das Heizelement ein durchgehendes Heizelement darstellt, das aus mehreren benachbarten Heizeinheiten besteht. Die Positionserkennungsvorrichtung kann bei einem Induktionsmodul beispielsweise durch eine oder mehrere Signalwindungen gebildet sein, die in die Windung der Spule des Heizelementes, die zur Erzeugung eines magnetischen Wechselfeldes dient, eingearbeitet ist oder sind. Hierdurch kann durch die Abwandlung oder AbschwƤchung des magnetischen Wechselfeldes erkannt werden, ob sich ein GargutbehƤlter auf dem Heizelement, das heiƟt auf der Deckplatte Ć¼ber dem Heizelement befindet. In AbhƤngigkeit der Position des GargutbehƤlters kann dann das oder kƶnnen dann die Heizelemente beziehungsweise Heizeinheiten des Heizelementes angesteuert werden, die unterhalb des GargutbehƤlters liegen.According to the invention, the combination appliance has a position detection device for detecting the position of a cooking vessel on the hob. According to the invention, the position detection device is connected to the vapor extraction device. The position detection device can be integrated in the heating element. In particular, in the case of a heating element that represents an induction module, the position detection device can be integrated in the heating element. However, other position detection devices, such as optical position detection devices, can also be used according to the invention. According to the invention, a position detection device is provided in a combination device in which the heating element is a continuous heating element consisting of several adjacent heating units. In the case of an induction module, the position detection device can be formed, for example, by one or more signal windings, which is or are worked into the winding of the coil of the heating element, which is used to generate an alternating magnetic field. As a result, the modification or weakening of the alternating magnetic field can be used to identify whether a container for cooking is located on the heating element, ie on the cover plate above the heating element. Depending on the position of the cooking product container, the heating element(s) or heating units of the heating element located below the cooking product container can then be controlled.

Indem die Positionserkennungsvorrichtung erfindungsgemƤƟ zudem mit der Dunstabzugsvorrichtung verbunden ist, kann auch die Dunstabzugsvorrichtung in AbhƤngigkeit von der Position eines GargutbehƤlters angesteuert werden. Ist bei einer AusfĆ¼hrungsform des KombinationsgerƤtes, bei der die Aussparungen an den seitlichen Randbereichen vorgesehen sind und bei der jeder Aussparung mindestens ein GeblƤse zugeordnet ist, das heiƟt Luft Ć¼ber mindestens ein GeblƤse durch jede Aussparung angesaugt wird, ein GargutbehƤlter beispielsweise in der NƤhe der linken Aussparung positioniert, so kann das entsprechende GeblƤse oder die entsprechenden GeblƤse, die dieser Aussparung zugeordnet sind, angesteuert werden. Somit kann die Absaugung der Luft aus dem Raum oberhalb des Kochfeldes auf den Bereich begrenzt werden, an dem in der Tat DĆ¼nste und Wrasen entstehen. Das GeblƤse oder die GeblƤse, die der rechten Aussparung zugeordnet sind, kƶnnen in dieser Situation entweder ausgeschaltet sein, oder bei einer geringeren Drehzahl betrieben werden.Since the position detection device is also connected to the vapor extraction device according to the invention, the vapor extraction device can also Depending on the position of a food container are controlled. In one embodiment of the combination appliance, in which the cutouts are provided on the lateral edge regions and in which at least one fan is assigned to each cutout, i.e. air is sucked in through each cutout by at least one fan, a container for cooking is, for example, in the vicinity of the left cutout positioned, the corresponding fan or fans that are associated with this recess can be controlled. In this way, the extraction of air from the space above the hob can be limited to the area where vapors and fumes are actually generated. In this situation, the fan or fans associated with the right recess can either be switched off or run at a lower speed.

Die Positionserkennungsvorrichtung kann zu diesem Zweck mit der Steuerung fĆ¼r einen Motor des GeblƤses verbunden sein. ZusƤtzlich oder alternativ kann die Positionserkennungsvorrichtung auch mit der Steuerung mindestens einer Abdeckung der mindestens einen Aussparung verbunden sein.For this purpose, the position detection device can be connected to the controller for a motor of the fan. Additionally or alternatively, the position detection device can also be connected to the controller of at least one cover of the at least one recess.

Als Abdeckung der Aussparung kann eine Platte verwendet werden, die die Aussparung zumindest bereichsweise abdeckt. Deckt die Abdeckung die Aussparung vollstƤndig ab, so kann diese vorzugsweise von der Aussparung abgenommen werden, wenn die Dunstabzugsvorrichtung betrieben wird. Statt der vollstƤndigen Abnahme der Abdeckung von der Aussparung kann die Abdeckung beispielsweise auch aufgeklappt, verdreht oder verschoben werden und so einen Spalt zwischen der Abdeckung und der Aussparung freigeben, Ć¼ber den Luft eingesaugt werden kann. Indem die Positionserkennungsvorrichtung mit der Steuerung einer solchen Abdeckung verbunden ist, kann die Abdeckung, die dem GargutbehƤlter am nƤchsten ist, bei Erkennen der Position des GargutbehƤlters geƶffnet werden. Hierdurch wird die Absaugung von Luft aus dem Raum oberhalb des Kochfeldes weiter verbessert. Zudem kann durch das Vorsehen einer Abdeckung das Eindringen von Verunreinigungen und FlĆ¼ssigkeiten in die Aussparung zumindest zeitweise verhindert werden.A plate which covers the recess at least in certain areas can be used to cover the recess. If the cover completely covers the cutout, it can preferably be removed from the cutout when the extractor hood is in operation. Instead of completely removing the cover from the cutout, the cover can also be opened, twisted or shifted, for example, and in this way release a gap between the cover and the cutout, through which air can be sucked in. Because the position detection device is connected to the controller of such a cover, the cover that is closest to the cooking container can be opened when the position of the cooking container is detected. This further improves the extraction of air from the space above the hob. In addition, by providing a cover, the ingress of contaminants and liquids into the recess can be prevented at least temporarily.

Das Kochfeld und die Dunstabzugsvorrichtung kƶnnen erfindungsgemƤƟ mittelbar oder unmittelbar aneinander befestigt sein. Bei einer unmittelbaren Befestigung kann beispielswiese die Seite des GeblƤses der Dunstabzugsvorrichtung, in der die Lufteintrittsƶffnung vorgesehen ist, an dem Kochfeld, beispielsweise an der Unterseite eines KochfeldgehƤuses befestigt sein.According to the invention, the hob and the extractor device can be attached directly or indirectly to one another. With a direct attachment, for example, the side of the fan of the extractor device in which the Air inlet opening is provided to be attached to the hob, for example on the underside of a hob housing.

Eine mittelbare Befestigung des Kochfeldes und der Dunstabzugsvorrichtung kann beispielsweise durch ein GerƤtegehƤuse realisiert werden. Bei dieser AusfĆ¼hrungsform sind das Kochfeld und die Dunstabzugsvorrichtung in einem gemeinsamen GerƤtegehƤuse aufgenommen. Das GerƤtegehƤuse kann hierbei insbesondere einen Wannenform aufweisen. Nach oben wird das GerƤtegehƤuse durch das Kochfeld und insbesondere durch die Deckplatte des Kochfeldes abgeschlossen. In dem GerƤtegehƤuse ist zudem ein Luftauslass eingebracht. Der Luftauslass kann beispielsweise an der RĆ¼ckseite des GerƤtegehƤuses vorgesehen sein. Alternativ ist es aber auch mƶglich, dass der Luftauslass an einer der SeitenwƤnde des GerƤtegehƤuses eingebracht ist oder in den Boden des GerƤtegehƤuses eingebracht ist. In dem GerƤtegehƤuse ist vorzugsweise zumindest die Dunstabzugsvorrichtung des KombinationsgerƤtes befestigt. Das Kochfeld kann entweder von oben in das GerƤtegehƤuse eingebracht werden und beispielsweise mit der Deckplatte auf der Oberkante der WƤnde des GerƤtegehƤuses aufliegen. Alternativ oder zusƤtzlich kƶnnen aber auch die Heizelemente des Kochfeldes beispielsweise an der Innenseite des GerƤtegehƤuses befestigt sein, oder gehalten werden.An indirect attachment of the hob and the extractor device can be implemented, for example, by an appliance housing. In this embodiment, the hob and the vapor extraction device are accommodated in a common appliance housing. In this case, the device housing can in particular have a trough shape. At the top, the device housing is closed off by the hob and in particular by the cover plate of the hob. There is also an air outlet in the device housing. The air outlet can be provided, for example, on the back of the device housing. Alternatively, however, it is also possible for the air outlet to be installed on one of the side walls of the device housing or in the bottom of the device housing. At least the extractor device of the combination device is preferably attached in the device housing. The hob can either be introduced into the device housing from above and, for example, rest with the cover plate on the upper edge of the walls of the device housing. Alternatively or additionally, however, the heating elements of the hob can also be fastened or held, for example, on the inside of the appliance housing.

Indem in dem KombinationsgerƤt die Dunstabzugsvorrichtung und das Kochfeld mittelbar oder unmittelbar miteinander verbunden sind, ist sowohl der Zusammenbau als auch die Montage des KombinationsgerƤtes vereinfacht. Beim Zusammenbau ist beim Vorsehen eines GerƤtegehƤuses die relative Position zwischen den Bauteilen der Dunstabzugsvorrichtung und dem Kochfeld bereits vorgegeben. Bei der Montage, insbesondere dem Einbringen in eine Arbeitsplatte, kƶnnen die in dem GerƤtegehƤuse eingebrachten Bauteile der Dunstabzugsvorrichtung und des Kochfeldes oder die aneinander befestigten Dunstabzugsvorrichtung und Kochfeld, in einem Montageschritt in eine Arbeitsplatte oder eine andere OberflƤche eingebracht werden. Sofern die Deckplatte ein zu den Heizelementen separates Bauteil des Kochfeldes darstellt, kann diese gegebenenfalls nachtrƤglich aufgelegt werden.Since the extractor device and the hob are connected to one another directly or indirectly in the combination device, both the assembly and the installation of the combination device are simplified. When assembling the relative position between the components of the vapor extraction device and the hob is already specified when providing a device housing. During assembly, in particular when being installed in a worktop, the components of the extractor device and the hob installed in the appliance housing or the extractor device and hob attached to one another can be installed in a worktop or another surface in one assembly step. If the cover plate is a component of the hob that is separate from the heating elements, it can optionally be placed on later.

GemƤƟ einer bevorzugten AusfĆ¼hrungsform weisen das Kochfeld und die Dunstabzugsvorrichtung des KombinationsgerƤtes einen gemeinsamen elektrischen Netzanschluss auf. Dieser Netzanschluss kann beispielsweise an dem GerƤtegehƤuse vorgesehen sein und die elektrischen Bauteile der Dunstabzugsvorrichtung und des Kochfeldes mit Spannung versorgen. Weiterhin kann auch die Ansteuerung der Bauteile der Dunstabzugsvorrichtung und des Kochfeldes durch ein gemeinsames SteuergerƤt erfolgen. Beispielsweise kann die Dunstabzugsvorrichtung dabei in AbhƤngigkeit des Betriebszustandes des Kochfeldes betƤtigt werden.According to a preferred embodiment, the hob and the vapor extraction device of the combination appliance have a common electrical connection mains connection on. This mains connection can be provided on the device housing, for example, and supply the electrical components of the extractor device and the hob with voltage. Furthermore, the components of the vapor extraction device and the cooktop can also be controlled by a common control unit. For example, the extractor device can be actuated depending on the operating state of the hob.

GemƤƟ einer bevorzugten AusfĆ¼hrungsform ist zwischen der mindestens einen Aussparung und der Dunstabzugsvorrichtung, insbesondere dem mindestens einen GeblƤse, das in dem KombinationsgerƤt angeordnet ist, ein Luftleitelement und / oder eine Filtereinheit vorgesehen. Hierdurch kann zum einen eine gezielte LuftfĆ¼hrung zu dem GeblƤse gewƤhrleistet werden. Zum anderen kann das Eindringen von verunreinigter Luft in das GeblƤse verhindert werden und so der Betrieb des GeblƤses sichergestellt werden. Das Luftleitelement kann beispielsweise einen Luftleitungskanal darstellen, der fest in dem KombinationsgerƤt eingebaut ist. ZusƤtzlich oder alternativ kann als Luftleitelement aber beispielsweise auch eine Filterhalterung darstellen, an der ein Filterelement gehalten wird. Zudem ist es auch mƶglich, dass das Luftleitelement zumindest bereichsweise als Sammelbereich oder SammelbehƤlter fĆ¼r FlĆ¼ssigkeiten dient. SchlieƟlich kƶnnen auch die WƤnde des GerƤtegehƤuses und der Boden des GerƤtegehƤuses, sowie die Unterseite des Kochfeldes, beispielsweise die Unterseite von GehƤusen der Heizelemente zur LuftfĆ¼hrung dienen und somit als Luftleitelement fungieren.According to a preferred embodiment, an air guide element and/or a filter unit is provided between the at least one cutout and the vapor extraction device, in particular the at least one fan that is arranged in the combination device. In this way, on the one hand, targeted air guidance to the blower can be ensured. On the other hand, the ingress of contaminated air into the fan can be prevented and the operation of the fan can thus be ensured. The air guiding element can, for example, represent an air duct that is permanently installed in the combination device. In addition or as an alternative, a filter holder, on which a filter element is held, can also be used as an air guiding element. In addition, it is also possible for the air guiding element to serve at least in certain areas as a collection area or collection container for liquids. Finally, the walls of the device housing and the bottom of the device housing, as well as the underside of the hob, for example the underside of housings for the heating elements, can also be used for air guidance and thus act as an air guide element.

In Figur 1 ist eine AusfĆ¼hrungsform des KombinationsgerƤtes 1 gezeigt. Das KombinationsgerƤt umfasst ein Kochfeld 10 und eine Dunstabzugsvorrichtung 11 von der in Figur 1 lediglich das GeblƤse 110 schematisch angedeutet ist. Die Dunstabzugsvorrichtung 11 ist unterhalb des Kochfeldes 10 angeordnet, so dass das GeblƤse 110 in der Draufsicht nur gestrichelt gezeigt ist. Das Kochfeld 10 besteht aus einer Deckplatte 103, die beispielsweise eine Glaskeramikplatte darstellen kann, und in der gezeigten AusfĆ¼hrungsform aus einem durchgehenden Heizelement 101, das unterhalb der Deckplatte 103 angeordnet ist beziehungsweise von der Deckplatte 103 abgedeckt wird. Vorzugsweise stellt das Heizelement 101 ein durchgehendes Heizelement 101 dar, das durch mehrere benachbarte Heizeinheiten 1010 gebildet wird. In der Figur 1 sind lediglich ein paar der Heizeinheiten 1010 angedeutet. Vorzugsweise liegen aber Ć¼ber die gesamte FlƤche des Heizelementes 101 verteilt benachbarte Heizeinheiten 1010 vor. Die Heizeinheiten 1010 kƶnnen beispielsweise Spulen darstellen, die von Strom durchflossen werden und so ein magnetisches Wechselfeld erzeugen. GargutbehƤlter (nicht gezeigt), die auf diese Heizeinheiten 1010 aufgesetzt werden, werden durch Induktion von Wirbelstrƶmen erhitzt. Der Bereich, in dem das Heizelement 101 unter der Deckplatte 103 vorgesehen ist, kann auch als Kochzone 102 bezeichnet werden. Die Kochzone 102 definiert hierbei den Bereich des Kochfeldes 10 in dem ein GargutgefƤƟ erwƤrmt werden kann. Sind mehrere Heizeinheiten 1010 vorgesehen, die teilweise aktiviert werden, so kann der Bereich, in dem ein GargutgefƤƟ tatsƤchlich auf dem Kochfeld 10 steht und erwƤrmt wird auch als Garzone bezeichnet werden. In der Kochzone 102 kƶnnen bei dieser AusfĆ¼hrungsform daher mehrere Garzonen vorliegen.In figure 1 an embodiment of the combination device 1 is shown. The combination device comprises a hob 10 and an extractor device 11 from the in figure 1 only the fan 110 is indicated schematically. The extractor device 11 is arranged below the hob 10, so that the fan 110 is only shown in broken lines in the plan view. The hob 10 consists of a cover plate 103, which can represent a glass ceramic plate, for example, and in the embodiment shown, a continuous heating element 101, which is arranged below the cover plate 103 or is covered by the cover plate 103. The heating element 101 is preferably a continuous heating element 101 formed by a plurality of adjacent heating units 1010 . In the figure 1 only a few of the heating units 1010 are indicated. However, adjacent heating units 1010 are preferably distributed over the entire surface of the heating element 101 . The heating units 1010 can, for example, represent coils through which current flows and thus generate an alternating magnetic field. Food containers (not shown) placed on these heating units 1010 are heated by induction of eddy currents. The area in which the heating element 101 is provided under the cover plate 103 can also be referred to as the cooking zone 102 . The cooking zone 102 defines the area of the hob 10 in which a cooking vessel can be heated. If several heating units 1010 are provided, some of which are activated, then the area in which a cooking product is actually standing on the hob 10 and is being heated can also be referred to as the cooking zone. In this embodiment, there can therefore be a number of cooking zones in the cooking zone 102 .

Die Deckplatte 103 weist eine Breite auf, die grĆ¶ĆŸer ist, als die Breite des Heizelementes 101. Hierdurch werden an den beiden Seiten des Heizelementes 101 ƜberstƤnde 105 gebildet. In die ƜberstƤnde 105 sind Aussparungen 104 in die Deckplatte 103 eingebracht. Die Aussparungen 104, die somit in den seitlichen Randbereichen der Deckplatte 103 liegen, weisen eine rechteckige Form auf und erstrecken sich in Tiefenrichtung des Kochfeldes 10, das heiƟt in der Richtung von der Vorderseite zu der RĆ¼ckseite des Kochfeldes. Die als lƤngliche Schlitze ausgebildeten Aussparungen 104 liegen zu dem Heizelement 101 benachbart, das heiƟt horizontal dazu versetzt in unmittelbarer NƤhe.The cover plate 103 has a width which is greater than the width of the heating element 101. As a result, 101 projections 105 are formed on the two sides of the heating element. Recesses 104 are made in the cover plate 103 in the projections 105 . The recesses 104, which are thus in the lateral edge regions of the cover plate 103, have a rectangular shape and extend in the depth direction of the hob 10, that is in the direction from the front to the back of the hob. The recesses 104 designed as elongated slots are adjacent to the heating element 101, that is to say offset horizontally thereto in the immediate vicinity.

In der AusfĆ¼hrungsform nach Figur 1 weist die Dunstabzugsvorrichtung 11 lediglich ein GeblƤse 110 auf, das zentral angeordnet ist. Der Aufbau des KombinationsgerƤtes 1 gemƤƟ der ersten AusfĆ¼hrungsform im Inneren wird spƤter unter Bezugnahme auf Figur 5 genauer erlƤutert.In the embodiment after figure 1 the extractor device 11 has only one fan 110 which is arranged centrally. The internal structure of the combination apparatus 1 according to the first embodiment will be described later with reference to FIG figure 5 explained in more detail.

In Figur 2 ist eine erste AusfĆ¼hrungsform des erfindungsgemƤƟen KombinationsgerƤtes 1 gezeigt. Diese AusfĆ¼hrungsform unterscheidet sich von der AusfĆ¼hrungsform nach Figur 1 lediglich dadurch, dass vier GeblƤse 110 vorgesehen sind. Die GeblƤse 110 sind als zwei vordere und zwei hintere GeblƤse 110 angeordnet. Es ist allerdings auch mƶglich, dass nur zwei, beispielsweise die zwei hinteren GeblƤse 110 vorgesehen sind.In figure 2 a first embodiment of the combination device 1 according to the invention is shown. This embodiment differs from the embodiment shown in FIG figure 1 merely by providing four blowers 110. The fans 110 are arranged as two front and two rear fans 110 . However, it is also possible that only two, for example the two rear, fans 110 are provided.

In Figur 3 ist eine zweite AusfĆ¼hrungsform des erfindungsgemƤƟen KombinationsgerƤtes 1 gezeigt. Diese AusfĆ¼hrungsform unterscheidet sich von der AusfĆ¼hrungsform nach Figur 1 lediglich dadurch, dass zwei GeblƤse 110 vorgesehen sind, die jeweils einer der Aussparungen 104 zugeordnet sind. Insbesondere liegt in der dritten AusfĆ¼hrungsform unter jeder der Aussparungen 104 jeweils ein GeblƤse 110. Die GeblƤse 110 sind hierbei in Tiefenrichtung in der Mitte der Aussparung 104 unter der Aussparung 104 angeordnet. Zudem ist in der dritten AusfĆ¼hrungsform eine Abdeckung 15 gezeigt, die auf jede der Aussparungen 104 aufgebracht ist. Die Abdeckungen 15 kƶnnen abnehmbar ausgestaltet sein. Es liegt aber auch im Rahmen der Erfindung, dass die Abdeckung 15 beispielsweise klappbar, drehbar oder verschiebbar an dem Kochfeld 10, insbesondere an der Deckplatte 103 befestigt ist. SchlieƟlich ist es auch mƶglich, dass die Abdeckung 15 Abmessungen aufweist, die geringer sind als die Abmessungen der Aussparung 104. Beispielsweise kƶnnen Abdeckungen 15 verwendet werden, die eine geringere Breite als die Aussparung 104 aufweisen. Hierdurch kann an der Seite der Aussparung 104, die dem Heizelement 101 zugewandt ist, ein Spalt (nicht gezeigt) gebildet werden, Ć¼ber den Luft in das KombinationsgerƤt 1 eingesaugt werden kann. Auch in der AusfĆ¼hrungsform nach Figur 1 und ersten AusfĆ¼hrungsform kƶnnen Abdeckungen 15 fĆ¼r die Aussparungen 14 vorgesehen sein.In figure 3 a second embodiment of the combination device 1 according to the invention is shown. This embodiment differs from the embodiment shown in FIG figure 1 merely in that two blowers 110 are provided, each associated with one of the recesses 104 . In particular, in the third embodiment, a blower 110 is located under each of the recesses 104. The blowers 110 are arranged here in the depth direction in the middle of the recess 104 under the recess 104. Also shown in the third embodiment is a cover 15 applied to each of the recesses 104 . The covers 15 can be designed to be removable. However, it is also within the scope of the invention for the cover 15 to be attached to the hob 10, in particular to the cover plate 103, such that it can be folded, rotated or displaced. Finally, it is also possible for the cover 15 to have dimensions that are smaller than the dimensions of the recess 104. For example, covers 15 that have a smaller width than the recess 104 can be used. As a result, a gap (not shown) can be formed on the side of the recess 104 that faces the heating element 101, through which gap air can be sucked into the combination device 1. Also in the embodiment after figure 1 and first embodiment, covers 15 may be provided for the recesses 14.

In Figur 4 ist eine dritte AusfĆ¼hrungsform des erfindungsgemƤƟen KombinationsgerƤtes 1 gezeigt. Diese AusfĆ¼hrungsform unterscheidet sich von der zweiten AusfĆ¼hrungsform lediglich dadurch, dass vier GeblƤse 110 vorgesehen sind, wobei jeweils zwei GeblƤse 110 jeweils einer der Aussparungen 104 zugeordnet sind. Insbesondere liegen in der dritten AusfĆ¼hrungsform unter jeder der Aussparungen 104 jeweils zwei GeblƤse 110. Die GeblƤse 110 sind hierbei in Tiefenrichtung verteilt unter der Aussparung 104 angeordnet.In figure 4 a third embodiment of the combination device 1 according to the invention is shown. This embodiment differs from the second embodiment only in that four fans 110 are provided, with two fans 110 each being assigned to one of the recesses 104 . In particular, in the third embodiment there are two blowers 110 under each of the recesses 104. The blowers 110 are distributed under the recess 104 in the depth direction.

Wird bei einer der in Figuren 1 bis 4 gezeigten AusfĆ¼hrungsformen, ein GargutgefƤƟ auf die Deckplatte 103 gesetzt, kann dessen Position auf dem Heizelement 101 vorzugsweise durch eine Positionserkennungsvorrichtung (nicht gezeigt) erkannt werden. Aufgrund der Position kƶnnen dabei die Heizeinheiten 1010 des Heizelementes 101 angesteuert werden, die unter dem GargutgefƤƟ liegen. Befindet sich diese Position in der NƤhe eines der seitlichen RƤnder des Heizelementes 101, so kann zudem die Dunstabzugsvorrichtung 11 entsprechend angesteuert, oder Abdeckungen 15 entsprechend eingestellt werden. Beispielsweise kann bei der ersten AusfĆ¼hrungsform beim Erkennen eines GargutgefƤƟes 15 im linken Randbereich eine Abdeckung (in Figur 1 nicht gezeigt) der linken Aussparung 104 angesteuert und dadurch geƶffnet werden.Is used at one of the in Figures 1 to 4 shown embodiments, a cooking product placed on the cover plate 103, its position on the heating element 101 can preferably be detected by a position detection device (not shown). Because of the position, the heating units 1010 of the heating element 101 that are below the cooking vessel can be controlled. If this position is in the vicinity of one of the lateral edges of the heating element 101, the extractor device 11 can also be controlled accordingly, or the covers 15 can be adjusted accordingly. For example, in the first embodiment, upon detection of a cooking product 15 in the left edge area, a cover (in figure 1 not shown) of the left recess 104 are controlled and thereby opened.

Bei der ersten, zweiten und dritten AusfĆ¼hrungsform kƶnnen zusƤtzlich zur Ansteuerung der Abdeckung 15 oder alternativ dazu ein oder mehrere GeblƤse 110 aktiviert werden, die in der NƤhe der erkannten Position des GargutgefƤƟes liegen.In the first, second and third specific embodiments, one or more fans 110 can be activated in addition to the control of the cover 15 or as an alternative to this, which are located in the vicinity of the detected position of the cooking product container.

Die Erfindung ist nicht auf die gezeigten AusfĆ¼hrungsformen begrenzt. Insbesondere kƶnnen die Aussparungen auch andere als die gezeigte rechteckige Form aufweisen. Beispielsweise kƶnnen mehrere zueinander benachbarte runde Aussparungen vorgesehen sein. Zudem ist es auch mƶglich, dass zusƤtzlich oder alternativ zu den gezeigten seitlich angeordneten Aussparungen zumindest eine Aussparung im rĆ¼ckwƤrtigen Randbereich des Kochfeldes eingebracht ist. Auch die Anzahl und Anordnung des / der GeblƤse ist nicht auf die gezeigten AusfĆ¼hrungsformen beschrƤnkt.The invention is not limited to the embodiments shown. In particular, the recesses can also have shapes other than the rectangular shape shown. For example, several round recesses adjacent to one another can be provided. In addition, it is also possible that in addition to or as an alternative to the laterally arranged recesses shown, at least one recess is made in the rear edge region of the hob. The number and arrangement of the fan(s) is also not limited to the embodiments shown.

In Figur 5 ist eine schematische Schnittansicht einer AusfĆ¼hrungsform des erfindungsgemƤƟen KombinationsgerƤtes 1 gezeigt. Die AusfĆ¼hrungsform nach Figur 5 entspricht der AusfĆ¼hrungsform nach Figur 1. ZusƤtzlich zu der in Figur 1 gezeigten AusfĆ¼hrungsform weist das KombinationsgerƤt 1 hierbei aber zusƤtzlich Abdeckungen 15 auf, die die Aussparungen 104 verschlieƟen kƶnnen. Das KombinationsgerƤt 1 ist in eine Arbeitsplatte 2 eingebracht. In dieser AusfĆ¼hrungsform des KombinationsgerƤtes 1 ist ein GerƤtegehƤuse 14 vorgesehen, in dem die Dunstabzugsvorrichtung 11 und das Kochfeld 10 aufgenommen sind. Das GeblƤse 110 der Dunstabzugsvorrichtung ist auf dem Boden 140 des GerƤtegehƤuses 14 angebracht. Das GeblƤse 110 weist ein GeblƤsegehƤuse 113 auf, in dessen Oberseite eine Lufteintrittsƶffnung 115 vorgesehen ist. Die Lufteintrittsƶffnung 115 kann durch ein Eingriffsschutzgitter (nicht gezeigt) abgedeckt sein. In dem GeblƤsegehƤuse 113 ist ein LĆ¼fterrad 112 angeordnet, das durch einen Motor 111 angetrieben wird. Von dem GeblƤsegehƤuse 113 wird die Luft Ć¼ber eine Luftaustrittsƶffnung (nicht gezeigt) aus dem GeblƤsegehƤuse 113 ausgegeben und in der dargestellten AusfĆ¼hrungsform in einen Luftauslasskanal 17 geleitet, Ć¼ber den die Luft zu einer Luftauslassƶffnung (nicht gezeigt) des GerƤtegehƤuses 14 gelangen kann und so aus dem KombinationsgerƤt 1 austreten kann. In der dargestellten AusfĆ¼hrungsform ist der Luftauslasskanal 17 zwischen dem Boden 140 des GerƤtegehƤuses 14 und einem darĆ¼ber liegenden LuftfĆ¼hrungskanal 16 gebildet, durch den Luft von den Aussparungen 14 zu der Lufteintrittsƶffnung 115 des GeblƤses 110 geleitet wird. Der Luftstrom L in dem KombinationsgerƤt 1 ist in Figur 5 schematisch durch Pfeile gezeigt. Der Boden des LuftfĆ¼hrungskanals 16 kann erfindungsgemƤƟ auch als Sammelbereich 122 fĆ¼r FlĆ¼ssigkeiten dienen. Der Sammelbereich 122 liegt hierbei tiefer als die Lufteintrittsƶffnung 115 des GeblƤsegehƤuses 113, um das Eintreten von FlĆ¼ssigkeiten in das GeblƤse 110 zu verhindern.In figure 5 a schematic sectional view of an embodiment of the combination device 1 according to the invention is shown. The embodiment after figure 5 corresponds to the embodiment figure 1 . In addition to the in figure 1 shown embodiment, the combination device 1 has additional covers 15 on, which can close the recesses 104. The combination device 1 is placed in a worktop 2 . In this embodiment of the combination appliance 1, an appliance housing 14 is provided, in which the extractor device 11 and the hob 10 are accommodated. The fan 110 of the fume extraction device is mounted on the floor 140 of the device housing 14 . The fan 110 has a fan housing 113, in the top of which an air inlet opening 115 is provided. The air inlet opening 115 can be covered by a protective grille (not shown). A fan wheel 112 which is driven by a motor 111 is arranged in the fan housing 113 . The air is discharged from the fan housing 113 via an air outlet opening (not shown) from the fan housing 113 and, in the illustrated embodiment, is directed into an air outlet duct 17, via which the air can reach an air outlet opening (not shown) of the device housing 14 and thus out of the Combination device 1 can escape. In the illustrated embodiment, the air outlet duct 17 is formed between the bottom 140 of the device housing 14 and an air duct 16 located above it, through which air is guided from the recesses 14 to the air inlet opening 115 of the fan 110 . The air flow L in the combination device 1 is in figure 5 shown schematically by arrows. According to the invention, the bottom of the air duct 16 can also serve as a collection area 122 for liquids. The collection area 122 is in this case lower than the air inlet opening 115 of the fan housing 113 in order to prevent liquids from entering the fan 110 .

Alternativ zu der gezeigten AusfĆ¼hrungsform, bei der das Kochfeld 10 und die Dunstabzugsvorrichtung 11 in einem GerƤtegehƤuse 14 aufgenommen sind, ist es erfindungsgemƤƟ auch mƶglich das KombinationsgerƤt 1 ohne GerƤtegehƤuse 14 auszufĆ¼hren. Bei einer solchen AusfĆ¼hrungsform kann dann beispielsweise die Oberseite des GeblƤses 110, das heiƟt die Seite in der die Lufteintrittsƶffnung 115 vorgesehen ist, in dem Bereich, der auƟerhalb der Lufteintrittsƶffnung 115 liegt, an der Unterseite eines KochfeldgehƤuses (nicht gezeigt) befestigt sein. Der LuftfĆ¼hrungskanal 16 wird hierbei beispielswiese durch ein Kanalelement gebildet.As an alternative to the embodiment shown, in which the hob 10 and the extractor device 11 are accommodated in an appliance housing 14, it is also possible according to the invention to design the combination appliance 1 without an appliance housing 14. In such an embodiment, for example, the top of the fan 110, i.e. the side in which the air inlet opening 115 is provided, can be attached to the underside of a cooktop housing (not shown) in the area that lies outside of the air inlet opening 115. The air duct 16 is in this case formed, for example, by a duct element.

In dem LuftfĆ¼hrungskanal 16 sind im Bereich der Aussparungen 104 Filterelemente 120 eingebracht. Der obere Teil des FĆ¼hrungskanals 16 dient daher als Filterhalterung 121 einer Filtereinheit 12, die zumindest ein Filterelement 120 umfasst. Die Aussparungen 104 werden nach oben durch Abdeckungen 15 verschlossen. In der in Figur 5 gezeigten Position sind die Aussparungen 104 geƶffnet, insbesondere sind die Abdeckungen 15 um deren ƤuƟeren Rand nach oben geklappt. Zwischen dem inneren Rand der Aussparung 104 und der Abdeckung 15 ist somit ein Spalt 150 gebildet. Zwischen den Aussparungen 104 ist unterhalb der Deckplatte 103 des Kochfeldes das Heizelement 101 angeordnet.Filter elements 120 are placed in the air duct 16 in the area of the recesses 104 . The upper part of the guide channel 16 therefore serves as a filter holder 121 of a filter unit 12 which comprises at least one filter element 120 . The recesses 104 are closed by covers 15 at the top. in the in figure 5 The position shown, the recesses 104 are open, in particular the covers 15 are folded up around their outer edge. A gap 150 is thus formed between the inner edge of the recess 104 and the cover 15 . The heating element 101 is arranged between the recesses 104 below the cover plate 103 of the hob.

ErfindungsgemƤƟ ist es auch mƶglich, dass das oder die GeblƤse 110 anstatt an dem Boden 140 des GerƤtegehƤuses 14 an der Unterseite des Kochfeldes 10, insbesondere an der Unterseite eines GehƤuses des oder der Heizelemente 101 abgebracht ist. Bei dieser AusfĆ¼hrungsform kann die Lufteintrittsƶffnung 115 des GeblƤses 110 nach unten weisen und die Luft kann von unten in das GeblƤse 110 eingesaugt werden.According to the invention, it is also possible for the fan or fans 110 to be attached to the underside of the hob 10 , in particular to the underside of a housing of the heating element or elements 101 , instead of to the bottom 140 of the appliance housing 14 . In this embodiment, the air inlet opening 115 of the fan 110 can point downwards and the air can be sucked into the fan 110 from below.

Mit der vorliegenden Erfindung wird eine integrierte Dunstabzugsvorrichtung, die auch als Haube bezeichnet werden kann, in einem Kochfeld, das auch als Kochplatte bezeichnet werden kann, geschaffen. Indem erfindungsgemƤƟ die Aussparungen im Randbereich des Kochfeldes, insbesondere in Form von zwei Schlitzen, von denen jeweils einer an jeder Seite des Kochfeldes liegt, vorgesehen sind, ist die Mitte des Kochfeldes frei von Ɩffnungen. Hierdurch kann unter anderem der Vorteil erzielt werden, dass ein flexibles Induktionsmodul als Heizelement fĆ¼r das Kochfeld verwendet werden kann. Als flexibles Induktionsmodul wird hierbei ein Heizelement bezeichnet, bei dem die Garzone dem GargutgefƤƟ folgt, wenn dieses verschoben wird. Da ein solches Kochfeld eine Topferkennung beinhaltet, kann erfindungsgemƤƟ die Regelung des KombinationsgerƤtes so konzipiert sein, dass nur dort angesaugt wird, wo tatsƤchlich auch ein Topf steht (links/rechts). Abdeckungen, die auch als Klappen bezeichnet werden kƶnnen, Ć¼ber den Aussparungen, die auch als Ansaugƶffnungen bezeichnet werden kƶnnen, kƶnnen so gesteuert werden, dass diese sich dann ƶffnen, wenn ein Topf daneben steht.With the present invention, an integrated extractor device, which can also be referred to as a hood, is created in a hob, which can also be referred to as a hotplate. Because according to the invention the recesses are provided in the edge region of the hob, in particular in the form of two slots, one of which is located on each side of the hob, the center of the hob is free of openings. As a result, the advantage can be achieved, inter alia, that a flexible induction module can be used as a heating element for the hob. A heating element in which the cooking zone follows the cooking vessel when it is moved is referred to as a flexible induction module. Since such a hob includes pot detection, the control of the combination appliance can be designed according to the invention in such a way that suction is only applied where there is actually a pot (left/right). Covers, which can also be called flaps, over the recesses, which can also be called suction openings, can be controlled in such a way that they open when a pot is standing next to them.

Ein Vorteil der vorliegenden Erfindung besteht darin, dass sich in der Mitte des Kochfeldes keine Ɩffnung befindet und die Tƶpfe somit beliebig verschoben werden kƶnnen. Zugleich wird durch das Vorsehen der Aussparungen im Randbereich und der Anordnung der Dunstabzugsvorrichtung in dem KombinationsgerƤt selber eine einfache und zuverlƤssige Absaugung von Luft aus dem Raum oberhalb des Kochfeldes gewƤhrleistet.An advantage of the present invention is that there is no opening in the middle of the hob and the pots can therefore be moved as desired. At the same time, the provision of the recesses in the edge area and the arrangement of the extractor device in the combination device itself ensure simple and reliable extraction of air from the space above the hob.
