Abstract
Description
Die Erfindung bezieht sich auf einen Backofen mit einer Mikrowelleneinrichtung und fakultativ mit einer thermischen Heizeinrichtung zum Garen von Lebensmitteln und mit einem durch Gebläse und Lüftungskanäle gebildeten Lüftungssystem zur frontseitigen Abführung einerseits der Betriebswärme aus dem Bereich des Mikrowellengenerators und andererseits von Wrasen aus dem Garraum.The invention relates to an oven with a microwave device and optionally with a thermal heater for cooking food and with a ventilation system formed by fan and ventilation ducts for front discharge on the one hand, the operating heat from the microwave generator and on the other hand of vapors from the oven.
Bei einem bekannten Backofen dieser Art (
Der vorliegenden Erfindung ist die Aufgabe gestellt, einen Backofen der eingangs genannten Art so auszugestalten, dass mit geringem Geräte- und insbesondere Teileaufwand eine frontseitige Be- und Entlüftung des Lüftungssystems und damit ein Einbau des Backofens auch in lüftungstechnisch ungünstige Küchenmöbel ermöglicht wird.The present invention has the object of providing an oven of the type mentioned in such a way that with low equipment and in particular parts of a front ventilation of the ventilation system and thus installation of the oven is also possible in ventilation unfavorable kitchen furniture.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, dass ein erstes Gebläse saugseitig an eine Einlassöffnung an der Ofenfrontseite angeschlossen ist und druckseitig und/oder saugseitig der Belüftung des Mikrowellengenerators und druckseitig der Belüftung des Garraumes dient, dass ein zweites Gebläse saugseitig an den Garraum und gegebenenfalls an den Umgebungsraum strömungstechnisch angeschlossen ist und dass wenigstens das zweite Gebläse druckseitig in einen Lüftungskanal einmündet, der mind. zu einer Ausblasöffnung an der Ofenfrontseite führt. Bei der Erfindung wird mit nur zwei Gebläsen des Lüftungssystems eine bestmögliche Abführung der Betriebswärme aus dem den thermisch stark belasteten Mikrowellengenerator aufweisenden Umgebungsraum des Garraumes und auch aus dem Garraum selbst - z.B. bei Grillbetrieb - erreicht sowie eine wirksame Zuführung von Kühlluft und beides ausschließlich von der Gerätefrontseite her bzw. zur Gerätefrontseite hin, sodass ein derartiger Backofen auch zum Einbau in den Backofen ohne Luftspalte eng umschließende Einbaumöbel geeignet ist.This object is achieved in that a first blower suction side is connected to an inlet opening on the furnace front side and the pressure side and / or suction side of the ventilation of the microwave generator and the pressure side of the ventilation Garraumes serves that a second fan is on the suction side connected to the cooking chamber and optionally to the surrounding space fluidly and that at least the second blower pressure side opens into a ventilation duct, the mind. Leads to a blowout on the furnace front. In the invention, with only two fans of the ventilation system best possible dissipation of heat from the operating the thermally heavily loaded microwave generator having environmental space of the cooking chamber and also from the cooking itself - eg grilling - achieved and effective supply of cooling air and both exclusively from the front panel forth or to the front of the device, so that such oven is also suitable for installation in the oven without air gaps tightly enclosing built-in furniture.
Eine vorteilhafte Weiterbildung der Erfindung ist dadurch gegeben, dass das zweite Gebläse in einem zentralen oberen Bereich eines den Mikrowellengenerator und elektrische Bauelemente für dessen Steuerung enthaltenden Umgebungsraumes angeordnet ist. Dieses vorzugsweise als Querstromgebläse ausgebildete zweite Gebläse hat mehrere Funktionen. Aufgrund seiner Platzierung im oberen Bereich des Umgebungsraumes des Backofens bzw. des Garraumes kann es z.B. saugseitig der Erfassung und Abführung der erhitzten Luft aus diesem Umgebungsraum, z.B. aus dem thermisch stark belastete oder wärmeempfindliche Bauelemente enthaltenden, so genannten Schalterraum, dienen und andererseits sorgt es für die Absaugung von z.B. während einem Grillvorgang entstehendem heißen Wrasen aus dem Garraum und somit auch für das Einhalten von niedrigen Temperatur- bzw. Grenzwerten im Backofengehäuse und in dessen Umgebung, sodass der Backofen auch dann verwendbar ist, wenn die Ofenrückseite lüftungstechnisch geschlossen, bzw. durch ein Einbaumöbel verschließbar ist, also keine rückseitige Kühlluftquelle vorhanden ist, bzw. benötigt wird.An advantageous development of the invention is given by the fact that the second fan is arranged in a central upper region of a space containing the microwave generator and electrical components for its control. This preferably designed as a cross-flow fan second fan has several functions. Due to its placement in the upper region of the ambient space of the oven or the cooking chamber can e.g. suction side of the detection and discharge of the heated air from this ambient space, e.g. from the thermally heavily loaded or heat-sensitive components containing so-called switch room, serve and on the other hand it provides for the extraction of e.g. during a grilling process arisen hot vapors from the oven and thus also for the maintenance of low temperature or limits in the oven housing and its surroundings, so that the oven is also used when the oven back is closed ventilation, or closed by a built-in furniture , So no backside cooling air source is present, or is needed.
Gemäß einer bevorzugten Ausführungsform der Erfindung mündet das erste Gebläse druckseitig strömungstechnisch im Anschluss an den Mikrowellengenerator und einen Lüftungseinlass des Garraumes in einen zur Ofenfrontseite führenden Lüftungskanal für eine Teilströmung des ersten Gebläses ein. Auch hier hat das erste Gebläse eine Doppelfunktion, nämlich die Wärmeabführung aus dem Bereich des Mikrowellengenerators mit thermisch stark belastetem Magnetron und Transformator sowie die Belüftung des Garraumes. In vorteilhafter Weise weist dabei der Garraum an zwei gegenüberliegenden Seitenwänden Strömungsöffnungen für die einströmende und ausströmende Luft auf, sodass hier von einer regelrechten Be- und Durchlüftung des Garraumes gesprochen werden kann. Dies eröffnet zusätzlich die Möglichkeit, einen besonders leistungsstarken Grillheizkörper im reinen Grillbetrieb oder im Kombinationsbetrieb mit Grill und Mikrowelle zu verwenden, der dann durch die genannte Durchlüftung des Garraumes auf eine angemessene Grilltemperatur gekühlt wird.According to a preferred embodiment of the invention, the first blower flows on the pressure side downstream of the microwave generator and a ventilation inlet of the cooking chamber into a leading to the furnace front ventilation duct for a partial flow of the first blower. Again, the first fan has a dual function, namely the heat dissipation from the range of the microwave generator with thermally heavily loaded magnetron and transformer as well as the ventilation of the cooking space. Advantageously, while the cooking chamber on two opposite side walls flow openings for the inflowing and outflowing air, so that it can be spoken of a proper ventilation of the cooking chamber here. This also opens up the possibility of using a particularly powerful grill heater in the pure grill mode or in combination mode with grill and microwave, which is then cooled by the said ventilation of the cooking chamber to an appropriate grill temperature.

In
In einem oberen, zentralen Bereich des den Garraum (6) umgebenden Umgebungsraum (14) befindet sich ein zweites, als Querstromlüfter ausgebildetes lang gestrecktes Gebläse (15), während sich in dem Raum (9) ein erstes, als Axiallüfter ausgebildetes Gebläse (16) befindet (
Nachstehend wird das mit den genannten Gebläsen (15,16) in Zusammenhang stehende Lüftungssystem des Backofens (1) erläutert, wobei dicke Lüftungspfeile, z.B. (17), in der Regel angesaugte Frischluft, bzw. zur Belüftung von Räumen und/oder Bauteilen noch verwendete Prozessluft verdeutlichen, während dünne Lüftungspfeile, z.B.

In der Frontplatte der Bodenwanne (8) befindet sich eine Einlassöffnung (19) für die Zuführung von Frischluft für das Lüftungssystem sowie mit Abstand daneben eine Ausblasöffnung (20) für abzuführende verbrauchte und erwärmte Abluft, getrennt durch einen Trennsteg (21), der die zugehörigen Lüftungskanäle strömungsmäßig voneinander trennt. Die Einlassöffnung (19) ist verbunden mit einem Lüftungskanal (22), der zur Saugseite des ersten Gebläses (16) führt. Druckseitig bläst dieses Gebläse (16) Kühlluft in den Raum (9) des Mikrowellengenerators (9/10) ein und kühlt denselben, indem die Betriebswärme vom Magnetron (10) und vom Transformator (11) durch einen Lüftungskanal (23) (
