Die Aufgabe der vorliegenden Erfindung ist die Bereitstellung eines Gargeräts mit einem verbesserten Aufbau.The object of the present invention is to provide a cooking appliance having an improved structure.
Erfindungsgemäß kann dies bei einem Gargerät nach dem Oberbegriff des Patentanspruchs dadurch erreicht werden, dass das Kühlluftgebläse neben einer Seitenwand der Gargerätemuffel angeordnet ist.According to the invention this can be achieved in a cooking appliance according to the preamble of the claim, characterized in that the cooling air blower is arranged adjacent to a side wall of the Gargerätemuffel.
Die Unteransprüche betreffen bevorzugte Ausführungsformen, welche einzeln oder in Kombination miteinander eingesetzt werden können.The subclaims relate to preferred embodiments which can be used individually or in combination with each other.
Der Vorteil eines solchen Gargeräts ist, dass aufgrund der Anordnung des Kühlluftgebläses neben einer Seitenwand zusätzlicher Bauraum oberhalb der Gargerätemuffel geschaffen werden kann. Dieser Bauraum kann beispielsweise für den Einbau von gerätespezifischen Vorrichtungen verwendet werden. Darüber hinaus ist es auch möglich, dass bei einer gleichbleibenden Höhe des Gargeräts im Vergleich zu den bestehenden Gargeräten eine Gargerätemuffel mit einer größeren Höhe realisiert werden kann.The advantage of such a cooking appliance is that due to the arrangement of the cooling air blower in addition to a side wall additional space above the cooking appliance muffle can be created. This space can be used for example for the installation of device-specific devices. In addition, it is also possible that at a constant height of the cooking appliance in comparison to the existing cooking appliances, a cooking appliance muffle can be realized with a greater height.
Unter einem Gargerät soll insbesondere ein Dampfgargerät verstanden werden. Mit einem Dampfgargerät kann ein druckloses Garen von Lebensmitteln durchgeführt werden, wenn eine Austrittsöffnung zum Druckausgleich zwischen dem Garraum und der umgebenden Atmosphäre vorgesehen ist. Das Dampfgargerät weist zum Verschließen und Öffnen der Austrittsöffnung ein Verschlusselement auf, welches zum Druckausgleich z. B. durch eine Betätigungseinrichtung geöffnet werden kann, so dass Wrasen aus dem Garraum durch die Austrittsöffnung ausströmen können. Das erfindungsgemäße Gargerät umfasst jedoch auch Backöfen, Herde, Mikrowellengeräte und dergleichen.Under a cooking appliance should be understood in particular a steam cooking appliance. With a Dampfgargerät a pressure-free cooking of food can be carried out when an outlet opening for pressure equalization between the cooking chamber and the surrounding atmosphere is provided. The Dampfgargerät has to close and open the outlet opening a closure element, which for pressure equalization z. B. can be opened by an actuator, so that fumes can flow out of the cooking chamber through the outlet opening. However, the cooking appliance according to the invention also includes ovens, cookers, microwave ovens and the like.
Das vorzugsweise als Radiallüfter ausgebildete Kühlluftgebläse bildet zusammen mit der daran angeschlossenen Kühlabluftvorrichtung ein Kühlsystem, welches im Wesentlichen drei Funktionen aufweisen kann. Mit Hilfe des Kühlsystems kann die Innentemperatur des Geräts gekühlt werden. Ferner ist es möglich, den Wrasen aus der Gargerätemuffel abzuführen. Des Weiteren ist die Kühlabluftvorrichtung des Kühlsystems dazu eingerichtet, den Dampf von dem Gehäuse, insbesondere der Bedienblende wegzuführen, so dass der Dampf nicht in unmittelbarer Umgebung des Gargeräts kondensiert und entsprechende Wassertropfen bildet.The cooling air blower, which is preferably designed as a radial fan, forms, together with the cooling exhaust device connected thereto, a cooling system which can essentially have three functions. With the help of the cooling system, the internal temperature of the device can be cooled. Furthermore, it is possible to remove the vapor from the cooking appliance muffle. Furthermore, the cooling exhaust device of the cooling system is adapted to carry away the steam from the housing, in particular the control panel, so that the steam is not condensed in the immediate vicinity of the cooking appliance and forms corresponding drops of water.
Unter der Anordnung des Kühlluftgebläses neben einer Seitenwand der Gargerätemuffel soll verstanden werden, dass sich das Kühlluftgebläse in einem Bereich befindet, welcher seitlich neben der Gargerätemuffel ist. Eine Befestigung des Kühlluftgebläses ist jedoch grundsätzlich an jeder Stelle des Gargeräts möglich. So kann beispielsweise vorgesehen sein, dass zwar das Kühlluftgebläse neben einer Seitenwand der Gargerätemuffel angeordnet ist, die Befestigung jedoch in geeigneter Weise an Bauteilen wie z. B. der Gehäusefront erfolgen, welche selbst nicht neben einer Seitenwand der Gargerätemuffel angeordnet sind.The arrangement of the cooling air blower next to a side wall of the cooking appliance muffle should be understood to mean that the cooling air blower is located in an area which is laterally adjacent to the cooking appliance muffle. An attachment of the cooling air blower is, however, basically possible at any point of the cooking appliance. For example, it may be provided that although the cooling air blower is arranged next to a side wall of the cooking appliance muffle, but the attachment in a suitable manner to components such. B. the front of the housing, which are not arranged next to a side wall of the cooking appliance muffle itself.
In einer vorteilhaften Weiterbildung ist vorgesehen, dass das Kühlluftgebläse bezogen auf eine Muffeldecke zumindest abschnittsweise in einer oberen Hälfte der Gargerätemuffel angeordnet ist. Darunter soll verstanden werden, dass zumindest ein Teil des Kühlluftgebläses mit einem Teil der Gargerätemuffel überlappt. So kann es beispielsweise vorgesehen sein, dass sich ein Teil des Kühlluftgebläses von der Seite her gesehen über die Muffeldecke erstreckt. Dies hat zum Vorteil, dass der Weg zwischen Kühlluftgebläse und der Kühlabluftvorrichtung verringert wird, was beispielsweise zu einer Verringerung des Druckverlusts führt.In an advantageous development, it is provided that the cooling air blower is arranged at least in sections in an upper half of the cooking appliance muffle with respect to a muffle cover. By this is to be understood that at least a part of the cooling air blower overlaps with a part of the cooking appliance muffle. For example, it may be provided that a part of the cooling air blower extends from the side over the muffle cover. This has the advantage that the path between the cooling air blower and the cooling exhaust device is reduced, which leads, for example, to a reduction in the pressure loss.
Eine vorteilhafte Weiterbildung sieht vor, dass das Kühlluftgebläse bezogen auf eine Gehäusefront in einer vorderen Hälfte der Gargerätemuffel angeordnet ist. Dadurch ist es ebenfalls möglich, kurze Wege zwischen dem Kühlluftgebläse und der Kühlabluftvorrichtung zu realisieren. Es kann beispielsweise vorgesehen sein, dass das Kühlluftgebläse im Wesentlichen bis zu der vorderen Gehäusefront reicht.An advantageous development provides that the cooling air blower is arranged relative to a front of the housing in a front half of the cooking appliance muffle. This also makes it possible to realize short distances between the cooling air blower and the cooling exhaust device. It can be provided, for example, that the cooling air blower substantially extends to the front housing front.
Es ist bevorzugt vorgesehen, dass das Kühlluftgebläse eine Luftausblasöffnung aufweist, welche im Wesentlichen vertikal unterhalb einer Lufteintrittsöffnung der Kühlabluftvorrichtung angeordnet ist. Dadurch kann eine verbesserte Ankopplung zwischen dem Kühlluftgebläse und der Kühlabluftvorrichtung realisiert werden. Darüber hinaus kann durch diese Anordnung erreicht werden, dass das Kühlluftgebläse in unmittelbarer Umgebung zu der Gehäusefront anordenbar ist und dadurch ebenfalls kurze Wege zwischen dem Kühlluftgebläse und der Kühlabluftvorrichtung realisiert werden können.It is preferably provided that the cooling air blower has an air outlet opening which is arranged substantially vertically below an air inlet opening of the cooling exhaust air device. Thereby, an improved coupling between the cooling air blower and the cooling exhaust device can be realized. In addition, it can be achieved by this arrangement that the cooling air blower can be arranged in the immediate vicinity of the housing front and thus also short distances between the cooling air fan and the cooling exhaust device can be realized.
Eine vorteilhafte Weiterbildung sieht vor, dass die Kühlabluftvorrichtung einen Luftströmungskanal umfasst, dessen Querschnittsfläche in Richtung eines ersten Luftstroms abnimmt. Das heißt, der Querschnitt des Luftströmungskanals nimmt mit zunehmender Entfernung von dem Kühlluftgebläse ab. Dadurch wird vorteilhaft erreicht, dass ein gleichmäßiger Luftstrom über nahezu die gesamte Breite des Gargeräts erzeugt wird.An advantageous development provides that the cooling exhaust device comprises an air flow channel whose cross-sectional area decreases in the direction of a first air flow. That is, the cross section of the air flow passage decreases with increasing distance from the cooling air blower. This advantageously ensures that a uniform air flow over almost the entire width of the cooking appliance is generated.
Ferner ist bevorzugt vorgesehen, dass der Luftströmungskanal im Bereich einer frontseitigen Luftauslassöffnung zumindest eine Prallplatte aufweist. Die Prallplatte ist dazu vorgesehen, den Luftstrom durch den Luftströmungskanal derart zu beeinflussen, dass dieser im Wesentlichen senkrecht zur Gehäusefront ausströmt. Vorzugsweise ragt die Prallplatte zumindest abschnittsweise in den Luftströmungskanal, so dass zumindest ein Teil des durch das Kühlluftgebläse erzeugten Luftstroms auf die Prallplatte trifft. Für den Fall, dass eine Mehrzahl von Prallplatten in dem Luftströmungskanal vorgesehen ist, ist es denkbar, dass alle Prallplatten gleich weit in den Luftströmungskanal ragen. Es kann jedoch ebenso vorgesehen sein, dass die Prallplatten mit zunehmender Entfernung zum Kühlluftgebläse weiter in den Luftströmungskanal ragen, so dass der durch das Kühlluftgebläse erzeugte Luftstrom zumindest teilweise auf jede der in den Luftströmungskanal angeordneten Prallplatten trifft. Des Weiteren kann vorgesehen sein, dass die Prallplatten eine unterschiedliche Geometrie z. B. bezüglich ihrer Höhe und/oder ihrer Krümmung aufweisen. So kann es beispielsweise vorgesehen sein, dass zumindest eine Prallplatte einer Mehrzahl Prallplatten zumindest einen gekrümmten Abschnitt aufweist, welcher insbesondere in Richtung des Kühlluftgebläses abgebogen ist. Dadurch kann erreicht werden, dass der auf die Prallplatte treffende Luftstrom zu der Vorderseite des Gargeräts verbessert abgelenkt wird.Furthermore, it is preferably provided that the air flow channel has at least one baffle plate in the region of a front air outlet opening. The baffle plate is provided to influence the air flow through the air flow channel such that it flows out substantially perpendicular to the housing front. Preferably, the baffle plate projects at least in sections into the air flow channel, so that at least part of the air flow generated by the cooling air blower strikes the baffle plate. In the event that a plurality of baffles is provided in the air flow channel, it is conceivable that all baffles protrude equally far into the air flow channel. However, it may also be provided that the baffles protrude further into the air flow channel with increasing distance to the cooling air blower, so that the air flow generated by the cooling air blower at least partially meets each of the baffles arranged in the air flow channel. Furthermore, it can be provided that the baffles have a different geometry z. B. with respect to their height and / or their curvature. For example, it may be provided that at least one baffle plate of a plurality of baffle plates has at least one curved section, which is bent in particular in the direction of the cooling air blower. As a result, it can be achieved that the air flow striking the baffle plate is deflected in an improved manner to the front side of the cooking appliance.
Eine vorteilhafte Weiterbildung sieht vor, dass die Kühlabluftvorrichtung einen im Wesentlichen winkelförmigen Abschnitt aufweist, durch welchen das Kühlluftgebläse den ersten Luftstrom in den Luftströmungskanal fördert. Der Luftströmungskanal kann mit dem winkelförmigen Abschnitt einstückig ausgebildet sein. Es ist jedoch ebenfalls denkbar, dass der winkelförmige Abschnitt als ein separater Adapter ausgebildet ist, welcher beispielsweise verschiedene Arten von Kühlluftgebläsen an die Kühlluftvorrichtung ankoppeln beziehungsweise verbinden kann.An advantageous development provides that the cooling exhaust device has a substantially angular section through which the cooling air blower promotes the first air flow in the air flow channel. The air flow channel may be formed integrally with the angled portion. However, it is also conceivable that the angle-shaped portion is formed as a separate adapter, which for example can couple or connect different types of cooling air blowers to the cooling air device.
Eine weitere vorteilhafte Weiterbildung sieht vor, dass die Kühlabluftvorrichtung einen Halteabschnitt aufweist, an welchem das Kühlluftgebläse gehalten ist, und/oder dass der Halteabschnitt und das Kühlluftgebläse korrespondierende Befestigungsmittel aufweisen. Bevorzugt kann vorgesehen sein, dass sich der Halteabschnitt an dem im Wesentlichen winkelförmigen Abschnitt befindet. Der Halteabschnitt der Kühlabluftvorrichtung hat zum Vorteil, dass keine zusätzlichen Halterungen vorgesehen werden müssen, an welchen das Kühlluftgebläse gehalten ist. Des Weiteren ermöglichen die korrespondierenden Befestigungsmittel am Halteabschnitt bzw. am Kühlluftgebläse eine einfache Verbindung derselben. So kann beispielsweise vorgesehen sein, dass der Halteabschnitt zumindest einen Stift aufweist, welcher sich im Wesentlichen senkrecht von dem Halteabschnitt erstreckt, und mit einer korrespondierenden Bohrung im Kühlluftgebläse nach erfolgter Montage des Kühlluftgebläses an der Kühlluftvorrichtung in Eingriff steht. Das heißt, das Kühlluftgebläse wird dadurch an der Kühlluftvorrichtung montiert, indem das Kühlluftgebläse mit der zumindest einen Bohrung auf den zumindest einen Stift aufgesteckt bzw. eingehängt wird. Aufgrund dieser Befestigungsart können auf weitere Befestigungsmittel wie z.B. Schrauben und dergleichen verzichtet werden. Ferner ist bevorzugt vorgesehen, dass das Kühlluftgebläse von der Gargerätemuffel durch einen Abstand seitlich beabstandet ist. Auf diese Weise kann erreicht werden, dass das Kühlluftgebläse nicht in direkten Kontakt mit der im Betrieb heißen Gargerätemuffel steht.A further advantageous development provides that the cooling exhaust device has a holding section, on which the cooling air blower is held, and / or that the holding section and the cooling air blower have corresponding fastening means. Preferably, it can be provided that the holding section is located on the substantially angled section. The holding portion of the cooling exhaust device has the advantage that no additional brackets must be provided, on which the cooling air blower is held. Furthermore, the corresponding fastening means on the holding section or on the cooling air blower enable a simple connection of the same. Thus, for example, be provided that the holding portion has at least one pin which extends substantially perpendicularly from the holding portion, and is in engagement with a corresponding bore in the cooling air blower after installation of the cooling air blower on the cooling air device. That is, the cooling air blower is thereby mounted on the cooling air device by the cooling air blower is attached or mounted with the at least one bore on the at least one pin. Due to this type of fastening can be dispensed with further fasteners such as screws and the like. Furthermore, it is preferably provided that the cooling air blower is laterally spaced from the cooking appliance muffle by a distance. In this way, it can be achieved that the cooling air blower is not in direct contact with the cooking appliance muffle that is hot during operation.
Vorzugsweise ist der Abstand durch die Dicke des Halteabschnitts gebildet. Dadurch lässt sich ein besonders stabiler Aufbau realisieren. Darüber hinaus kann vorgesehen sein, dass zwischen dem Kühlluftgebläse und der Gargerätemuffel eine Isolationsschicht eingebracht ist. Dies hat zum Vorteil, dass das Kühlluftgebläse gegenüber einer durch die Gargerätemuffel verursachten Überhitzung geschützt ist.Preferably, the distance is formed by the thickness of the holding portion. This makes it possible to realize a particularly stable construction. In addition, it can be provided that an insulating layer is introduced between the cooling-air fan and the cooking appliance muffle. This has the advantage that the cooling air blower is protected against overheating caused by the cooking appliance muffle.
Eine vorteilhafte Weiterbildung sieht vor, dass an der Kühlabluftvorrichtung eine Wrasenöffnung vorgesehen ist, durch welche ein zweiter Luftstrom zuführbar ist. Vorzugsweise befindet sich die Wrasenöffnung an der Unterseite des Luftströmungskanals. Es ist bevorzugt vorgesehen, dass die Wrasenöffnung in der Nähe des Kühlluftgebläses gebildet ist. Durch das Vorsehen der Wrasenöffnung in der Kühlluftvorrichtung bzw. in dem Luftströmungskanal ist es vorteilhaft nicht notwendig, weitere Luftauslassöffnungen für die Abführung des Wrasens in dem Gargerät vorzusehen.An advantageous development provides that at the cooling exhaust device a Wrasenöffnung is provided, through which a second air flow can be supplied. Preferably, the vapor opening is located at the bottom of the air flow channel. It is preferably provided that the vapor opening is formed in the vicinity of the cooling air blower. By providing the vapor opening in the cooling air device or in the air flow channel, it is advantageously not necessary to provide further air outlet openings for the removal of the vapor in the cooking appliance.
Vorzugsweise ist die Wrasenöffnung derart in der Kühlabluftvorrichtung angeordnet, dass durch den ersten Luftstrom des Kühlluftgebläses im Bereich der Wrasenöffnung ein Unterdruck erzeugbar ist. Dadurch kann erreicht werden, dass der durch das Kühlluftgebläse erzeugte erste Luftstrom den durch die Wrasenöffnung zugeführten Wrasen in Richtung der frontseitigen Luftauslassöffnungen mitnimmt. Mittels des ersten Luftstroms erfolgt sozusagen eine verstärkte Förderung des zweiten Luftstroms in Richtung der Luftauslassöffnungen.Preferably, the vapor opening is arranged in the cooling exhaust device such that a negative pressure can be generated by the first air flow of the cooling air blower in the region of the vapor opening. It can thereby be achieved that by the cooling air blower produced first air flow entrains the supplied through the Wrasenöffnung vapors in the direction of the front air outlet openings. By means of the first air flow takes place, so to speak, an increased promotion of the second air flow in the direction of the air outlet openings.
Eine weitere vorteilhafte Weiterbildung sieht vor, dass im Bereich der Wrasenöffnung ausgangsseitig eine Anordnung zum Verhindern eines Rückflusses von Kondenswasser in das Kühlluftgebläse, insbesondere eine in der Kühlabluftvorrichtung angeordnete Stufe vorgesehen ist. Durch die Stufe kann insbesondere erreicht werden, dass in das Kühlluftgebläse zurückfließendes Kondenswasser dieses nicht beschädigt. Stattdessen kann erreicht werden, dass in dem Luftströmungskanal angesammeltes Kondenswasser durch einen natürlichen Trocknungsprozess beseitigt wird.A further advantageous development provides that in the area of the vapor opening on the output side, an arrangement for preventing a backflow of condensed water into the cooling air blower, in particular a arranged in the cooling exhaust air stage is provided. The level can be achieved, in particular, that condensate flowing back into the cooling-air blower does not damage it. Instead, it can be achieved that condensed water accumulated in the air flow channel is eliminated by a natural drying process.
