Description

Die Erfindung bezieht sich auf einen Ofen zur Garbehandlung von Lebensmitteln mittels thermischer Energie und/oder Mikrowellenenergie, mit einem thermische Energie abgebenden bzw. thermisch empfindliche Bauelemente aufnehmenden, lüftungstechnisch begrenzten Schalterraum, der mittels erzwungener Kühlluft zur Abführung der Betriebswärme im Schalterraum zwangsbelüftet ist und innerhalb dessen ein Gehäuse für thermisch hochbelastete oder wärmeempfindliche Bauelemente vorgesehen ist, das strömungstechnisch mit mindestens einem Kühlluftgebläse des Schalterraumes in Verbindung ist.The invention relates to a furnace for cooking treatment of food by means of thermal energy and / or microwave energy, with a thermal energy absorbing or thermally sensitive components receiving, ventilation limited switch room, which is forced ventilated by means of forced cooling air to dissipate the heat in the switch room and within a housing for thermally highly stressed or heat-sensitive components is provided, which is fluidically connected to at least one cooling air blower of the switch room in combination.

Bei Öfen zur Garbehandlung von Lebensmitteln, bei Backöfen oder Herden ist es üblich, die elektrischen oder elektronischen Bauelemente in einem oberhalb der Ofenmuffel liegenden Schalterraum unterzubringen und diesen Raum zum Beispiel mit einem sogenannten Querstromgebläse zu kühlen. Bei Öfen mit alleiniger oder zusätzlicher Mikrowelleneinrichtung ist zur Kühlung des Hochfrequenzgenerators (Magnetron) üblicherweise ein separates Gebläse zum Beispiel ein Radialgebläse vorgesehen. Insbesondere bei sogenannten Kompaktöfen, also bei Öfen mit relativ geringen Außenabmessungen, die auch oberhalb des Küchenmöbels in Schränke oder dergleichen einbaubar sind ergeben sich Probleme zum Bespiel hinsichtlich des im Vergleich mit großen Herden kleineren Schalterraumes und dessen Kühlung, insbesondere dann, wenn der Ofen mit sämtlichen konventionellen Heizeinrichtungen wie Oberhitze, Unterhitze, Umluftheizung, pyrolytischer Selbstreinigungsbetrieb und dergleichen betrieben werden soll und wenn zusätzlich noch ein Mikrowellenbetrieb möglich sein soll. Bei Mikrowellenöfen ist es bekannt, einen sogenannten Inverternetzteil vorzusehen, welcher durch einen Leistungshalbleiter und einen Hochspannungstransformator gebildet wird. Bei bekannten Geräten wird ein derartiger Inverternetzteil im wesentlichen nur benutzt entweder bei reinen Mikrowellenöfen oder aber bei Mikrowellenöfen mit konventioneller thermischer Heizung mit relativ geringer Heizleistung, sodass die thermische Belastung der Umgebung des Behandlungsraumes, insbesondere des Schalterraumes in dem sich hitzeempfindliche und/oder elektronische Bauelemente und zusätzliche thermische Energie abgebende Bauelemente, wie zum Beispiel ein Magnetron der Mikrowelleneinrichtung befindet, relativ gering ist.In ovens for cooking treatment of foods, ovens or stoves, it is common to accommodate the electrical or electronic components in a lying above the furnace muffle switch room and to cool this room, for example, with a so-called cross-flow fan. In ovens with single or additional microwave device usually a separate fan, for example, a radial fan is provided for cooling the high frequency generator (magnetron). In particular, in so-called compact ovens, so ovens with relatively small external dimensions, which are also installed above the kitchen furniture in cabinets or the like, problems arise for example with regard to the smaller in comparison with large herds switch room and its cooling, especially if the oven with all conventional heaters such as top heat, bottom heat, convection heating, pyrolytic self-cleaning operation and the like to be operated and if in addition still a microwave operation should be possible. In microwave ovens, it is known to provide a so-called inverter power supply, which is formed by a power semiconductor and a high voltage transformer. In known devices such an inverter power supply is essentially only used either in pure microwave ovens or microwave ovens with conventional thermal heating with relatively low heat output, so that the thermal load on the environment of the treatment room, in particular the switch room in the heat-sensitive and / or electronic components and additional thermal energy dissipating devices, such as a magnetron of the microwave device is relatively low.

Aus der Druckschrift US 2004/0149752 ist ein Mikrowellengerät bekannt, die ein Inverter-Netzgerät zur Versorgung des Magnetrons, einen Halter zum Halten des Inverter-Netzgerätes und ein Kühllüfter zum Herunterkühlen des Inverter Netzgerätes beinhaltet. Der Halter besteht aus einem Halteteil zum Halten des Inverter- Netzgerätes und einem Luftleitteil zum Führen der Kühlluft vom Kühllüfter zum Inverter- Netzgerät. Der Luftleitteil deckt das Inverter- Netzgerät ab und führt die Kühlluft derart, dass vor allem ein Halbleiterschalter und ein Hochspannungstransformator des Inverter- Netzgerätes heruntergekühlt werden.From the publication US 2004/0149752 a microwave oven is known which includes an inverter power supply for supplying the magnetron, a holder for holding the inverter power supply and a cooling fan for cooling down the inverter power supply. The holder consists of a holding part for holding the inverter power supply unit and an air guide for guiding the cooling air from the cooling fan to the inverter power supply. The air guide part covers the inverter power supply unit and guides the cooling air in such a way that above all a semiconductor switch and a high voltage transformer of the inverter power supply unit are cooled down.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, bei einem Ofen der eingangs genannten Art eine bestmögliche Betriebstemperatur in dem thermisch hochbelastete oder besonders wärmeempfindliche Bauelemente enthaltenden Schalterraum auch bei Einschaltung sämtlicher Betriebsarten zu erhalten, auch dann, wenn für die Unterbringung dieser Bauelemente nur ein sehr begrenzter Raum zur Verfügung steht.The present invention has for its object to obtain in a furnace of the type mentioned in the best possible operating temperature in the thermally highly loaded or particularly heat-sensitive components containing switch room even when all operating modes, even if for the placement of these components only a very limited space is available.

Diese Aufgabe wird gemäß der Erfindung bei einem Ofen der eingangs genannten Art dadurch gelöst, dass innerhalb des Schalterraumes ein, einen eng begrenzten Raum bildendes Gehäuse für thermisch hoch belastete oder wärmeempfindliche Bauelemente vorgesehen ist, dass strömungstechnisch an mindestens ein Kühlluftgebläse des Schalterraumes angeschlossen ist.This object is achieved according to the invention in an oven of the type mentioned in that within the switch room, a narrow space forming housing for thermally highly loaded or heat-sensitive components is provided that is fluidly connected to at least one cooling air blower of the switch room.

Mit der erfindungsgemäßen Maßnahme wird insbesondere für extrem thermisch belastete, d. h. wärmeabgebende und/oder für extrem wärmeempfindliche Bauelemente oder Bauelemente/Einheiten wie ein Inverternetzteil der Mikrowelleneinrichtung eine Art Schutzraum innerhalb des Gehäuses geschaffen, in welchem Kühlluftströme mittels Luftleitelementen gezielt und bedarfsgerecht den zu kühlenden Stellen zugeleitet werden können. Aufgrund des begrenzten Raumes innerhalb des Gehäuses und damit der kurzen Strömungswege für die Kühlluft erzielt man damit ein direktes "Anblasen" dieser Bauelemente, verbunden mit einer verstärkten Wirbelbildung, d. h. einer turbulenten Strömung der objektbezogenen Kühlluftströme und damit eine optimale Kühl- bzw. Wärmeabführwirkung.With the measure according to the invention, in particular for extremely thermally loaded, ie heat-emitting and / or extremely heat-sensitive components or units / units such as an inverter power supply of the microwave device created a kind of shelter within the housing, fed in which cooling air flows targeted by air guide elements and needs to be cooled points can be. Due to the limited space within the housing and thus the short flow paths for the cooling air to achieve a direct "blowing" of these components, combined with an increased vortex formation, ie a turbulent flow of object-related cooling air flows and thus optimal cooling or heat dissipation effect.

Das Gehäuse ist nach Art eines Strömungskanals ausgebildet und ist einerseits an die Außenluft und andererseits an die Saugseite des mindestens einen Kühlluftgebläses strömungstechnisch angeschlossen. In den meisten Fällen wird es vorteilhaft sein, das Gehäuse mit seiner Saugseite an der rückwärtigen Begrenzung des Ofens anzuordnen, an welcher Ofenseite erfahrungsgemäß die Außenluft vom Ofen am geringsten erwärmt wird.The housing is designed in the manner of a flow channel and is fluidly connected on the one hand to the outside air and on the other hand to the suction side of the at least one cooling air blower. In most cases, it will be advantageous to arrange the housing with its suction side at the rear boundary of the furnace, on which furnace side, according to experience, the outside air from the furnace is the least heated.

Gemäß einer vorteilhaften Ausgestaltung der Erfindung weist das Gehäuse mehrere Luft-Austrittsöffnungen auf, die zumindest teilweise der Saugseite des zumindest einen Kühlluftgebläses zugewandt sind. So kann zum Beispiel eine Luft-Austrittsöffnung einem separaten Kühlluftgebläse für das Magnetron der Mikrowelleneinrichtung zugeordnet sein, während eine weitere Austrittsöffnung zum Beispiel in Form einer Lochgruppe der Saugseite eines Kühlluftgebläses zugewandt sein kann, welches Kühlluftgebläse in Form eines Querstromlüfters allgemein der Wärmeabführung aus dem Schalterraum dient. Die mehreren Luft-Austrittsöffnungen können derart angeordnet sein, dass zum Beispiel senkrecht aufeinanderstehende Abluftströme gebildet werden, unterstützt durch entsprechende Platzierung der Luftleitelemente.According to an advantageous embodiment of the invention, the housing has a plurality of air outlet openings, which are at least partially facing the suction side of the at least one cooling air blower. Thus, for example, an air outlet opening can be assigned to a separate cooling-air fan for the magnetron of the microwave device, while a further outlet opening, for example in the form of a group of holes, can face the suction side of a cooling-air fan, which cooling-air fan in the form of a cross-flow fan generally serves to dissipate heat from the switch compartment , The plurality of air outlet openings may be arranged such that, for example, mutually perpendicular exhaust air streams are formed, supported by appropriate placement of the air guide elements.

Es ist vorteilhaft, wenn das Gehäuse mit Stellfüßen versehen und mit Luftabstand an seinem Träger befestigt ist. Auf diese Weise wird das Gehäuse selbst von einem mit der Außenluft kommunizierenden Luftpolster umgeben, welches für eine Wärmeabführung an zumindest der unteren Außenseite des Gehäuses sorgt.It is advantageous if the housing is provided with adjustable feet and secured with air clearance on its support. In this way, the housing itself is surrounded by a communicating with the outside air cushion, which provides heat dissipation to at least the lower outside of the housing.

Weitere Einzelheiten der Erfindung ergeben sich aus dem in der Zeichnung dargestellten und nachstehend beschriebenen Ausführungsbeispielen.Further details of the invention will become apparent from the illustrated in the drawings and described below embodiments.

Es zeigt:

das Gehäuse gemäß Figur 1, bestehend aus einem unteren Formteil (Figur 2) und einem oberen Formteil (Figur 3).
It shows:
FIG. 1
View on the open top of a furnace, not shown,
FIGS. 2 and 3
the housing according to FIG. 1 consisting of a lower molding ( FIG. 2 ) and an upper molding ( FIG. 3 ).

Die in Figur 1 gezeigte oberste Etage des Ofens bildet einen Schalterraum 1, der an beiden Seiten umgeben ist von nur gestrichelt dargestellten Seitenwänden 2 und rückseitig durch eine ebenfalls gestrichelt dargestellte Rückwand 3 und nach oben hin durch eine Deckplatte 4 und ggf. noch durch eine ebenfalls nicht dargestellte obere Zwischenplatte. In diesem Schalterraum 1 untergebracht sind elektrische oder elektronische Bauelemente für die Steuerung und Regelung von sogenannten konventionellen Heizelementen wie eine Oberhitze/Grill, eine Unterhitze unterhalb einer ebenfalls nicht dargestellten Ofenmuffel, die unmittelbar unterhalb des Schalterraumes 1 platziert ist. Der Ofen soll also ausgerüstet sein mit sämtlichen denkbaren Heizelementen für den konventionellen Ofenbetrieb einschließlich Umluftbetrieb und Selbstreinigungsbetrieb, bei dem im Inneren oder Ofenmuffel Temperaturen bis zu nahezu 500 Grad C auftreten. Basis dieses Schalterraumes 1 ist eine Grundplatte 5. Da der Ofen auch für den Mikrowellenbetrieb eingerichtet sein soll, ist im Schalterraum 1 ferner eine Mikrowelleneinrichtung angeordnet mit einem Magnetron 6, mit einem Radiallüfter 7, an dessen Druckseite ein zum Magnetron 6 führender Luftschacht 8 angeordnet ist, sowie mit einem Inverternetzteil der Mikrowelleneinrichtung, welcher innerhalb eines anhand der Figuren 2 und 3 erklärten Gehäuses 9 angeordnet ist. Die das Magnetron 6 umströmende, nunmehr erwärmte Kühlluft gelangt in einen im Bereich der Frontseite 10 des Ofens angeordneten Abluftschacht 11 und von hier aus ins Freie. Diese Abluftströmung ist durch Pfeile 12 verdeutlicht. Ferner sind im Schalterraum 1 untergebracht ein Kühlluftgebläse 13, das als Querstromlüfter ausgebildet ist sowie weitere Bauelemente oder Bauelementegruppen, die üblicherweise bei derartigen Öfen oder Herden verwendet werden. Wie ferner in Figur 1 gezeigt, ist der Radiallüfter 7 mit seiner Saugseite unmittelbar an die Stirnseite 14 des Gehäuses 9 angeschlossen, während sich das Kühlluftgebläse 13 an einer Längsseite 15 des Gehäuses 9 befindet. Das Gehäuse 9 selbst ist unmittelbar an der Rückseite des Ofens und damit auch des Schalterraumes 1 derart angeordnet, dass seine Lufteintrittsöffnungen 16, 17, 18 an der Ofenrückseite unmittelbar an die Außenluft angeschlossen sind. Hierzu sind in der Rückwand 3 entsprechende Lufteintrittsöffnungen zum Beispiel in Form einer Lochgruppe vorgesehen.In the FIG. 1 shown top floor of the furnace forms a switch room 1, which is surrounded on both sides by dashed lines shown side walls 2 and back by a dashed lines shown back wall 3 and up through a cover plate 4 and possibly also by an upper intermediate plate also not shown , Housed in this switch room 1 are electrical or electronic components for the control and regulation of so-called conventional heating elements such as a top heat / grill, a bottom heat below a likewise not shown oven muffle, which is placed directly below the switch room 1. The oven should therefore be equipped with all conceivable heating elements for conventional oven operation including recirculation mode and self-cleaning mode, in which temperatures up to almost 500 degrees C occur inside or Ofenmuffel. Base of this switch room 1 is a base plate 5. Since the oven should also be set up for microwave operation, a microwave device is further arranged in the switch room 1 with a magnetron 6, with a radial fan 7, at the pressure side of a magnetron 6 leading duct 8 is arranged , As well as with an inverter power supply of the microwave device, which within a reference to the FIGS. 2 and 3 explained housing 9 is arranged. The magnetron 6 flowing around, now heated cooling air passes into a arranged in the front side 10 of the furnace exhaust duct 11 and from here into the open. This exhaust air flow is illustrated by arrows 12. Further, in the switch room 1 housed a cooling air blower 13, which is designed as a cross-flow fan and other components or component groups that are commonly used in such ovens or stoves. As further in FIG. 1 shown, the radial fan 7 is connected with its suction side directly to the end face 14 of the housing 9, while the cooling air blower 13 is located on a longitudinal side 15 of the housing 9. The housing 9 itself is arranged directly on the back of the furnace and thus also of the switch room 1 such that its air inlet openings 16, 17, 18 are connected to the oven rear side directly to the outside air. For this purpose, 3 corresponding air inlet openings are provided, for example in the form of a hole group in the rear wall.

Wie anhand von Figur 1 und der Figuren 2 und 3 erläutert, besitzt das Gehäuse 9 mehrere Luftaustrittsöffnungen, zum Beispiel 19, die mit der Saugseite des Radiallüfters 7 kommunizieren sowie eine Luftaustrittsöffnung 20 in Form einer Lochgruppe, die der Saugseite des Kühlluftgebläses 13 zugewandt ist. Das Gehäuse 9 besteht aus zwei zusammensetzbaren und verbindbaren Formteilen 9a und 9b, wobei der Formteil 9a die Unterseite und der Formteil 9b die Oberseite des Gehäuses 9 darstellt. Die Figuren 2 und 3 zeigen die beiden Formteile 9a und 9b auseinandergeklappt. Jeder Formteil 9a und 9b besitzt hinter den Lufteintrittsöffnungen 16, 17, 18 gebogene und langgestreckte Luftleitelemente 21, 22, 23, welche insgesamt drei im wesentlichen parallel zueinander verlaufende Kanalabschnitte für die von außen her in Pfeilrichtung 24 einströmende Kühlluft bilden. Anschließend an diese Kanalabschnitte und Luftleitelemente 21, 22 und 23 befinden sich weitere Luftleitelemente, zum Beispiel 25 und 26, durch welche die in den Kanalabschnitten herangeführte Kühlluft (Pfeile 24) verwirbelnd in Richtung zum Beispiel der Pfeile 27 verteilt wird in Richtung von thermisch hoch belasteten und daher zu kühlenden Bauelementen der Mikrowelleneinrichtung zum Beispiel in Richtung einer Hochfrequenzspule 28, eines Kühlkörpers 29 des Inverternetzteils sowie in Richtung einer nur angedeuteten Platine 30 ebenfalls des Inverternetzteils, welche Platine 30 im Unterteil des Gehäuses 9 mit Abstand zu den Gehäusewänden angeordnet ist, so dass die Kühlluftströmung beide Platinenseiten umstreichen kann. Durch die strömungstechnische Ankopplung der im Inneren des Gehäuses 9 strömenden Kühlluftströme über die Luftaustrittsöffnungen 19 und 20 an die Saugseiten der beiden Kühlluftgebläse 7, 13 sowie durch das Vorhandensein der vorgenannten Luftleitelemente erhält man wenigstens zwei im wesentlichen senkrecht aufeinanderstehende Abluftströmungen in Richtung der Pfeile 31 in Richtung des Radiallüfters 7 und in Pfeilrichtung 32 in Richtung zum Kühlluftgebläse 13, wie in Figur 1 verdeutlicht. Die Luftaustrittsöffnungen 20 in Form von Lochgruppen sind im Oberteil 9b des Gehäuses 9, also in unmittelbarer des Nähe der Saugseite des Kühlluftgebläses 13 angeordnet und dienen insbesondere zur Wärmeabführung aus dem Bereich der Leistungshalbleiter und des Hochspannungstransformators des Inverternetzteils der Mikrowelleneinrichtung. Am Bodenteil des Formteils 9a des Gehäuses 9 sind Stellfüße 33 angeformt, mit welchen das Gehäuse 9 mit Luftabstand auf der Grundplatte 5 ruht (siehe Figur 1 und 2). Aufgrund dieses Luftabstandes 34 oder Spaltes kann in Pfeilrichtung 35 Kühlluft auch die Unterseite des Gehäuses 9 umströmen, womit auch das Gehäuse selbst zwangsgekühlt wird.As based on FIG. 1 and the FIGS. 2 and 3 explained, the housing 9 has a plurality of air outlet openings, for example 19, which communicate with the suction side of the radial fan 7 and an air outlet opening 20 in the form of a group of holes, the Suction side of the cooling air blower 13 faces. The housing 9 consists of two composable and connectable molded parts 9a and 9b, wherein the molded part 9a represents the underside and the molded part 9b represents the upper side of the housing 9. The FIGS. 2 and 3 show the two mold parts 9a and 9b unfolded. Each molded part 9a and 9b has behind the air inlet openings 16, 17, 18 bent and elongated air guide elements 21, 22, 23, which form a total of three substantially mutually parallel channel sections for the incoming from the outside in the direction of arrow 24 cooling air. Subsequent to these channel sections and air guide elements 21, 22 and 23 there are further air guide elements, for example 25 and 26, through which the cooling air introduced in the channel sections (arrows 24) is distributed in a swirling manner in the direction of the arrows 27, for example, in the direction of high thermal loads and therefore to be cooled components of the microwave device, for example in the direction of a high-frequency coil 28, a heat sink 29 of the inverter power supply and in the direction of an only indicated board 30 also the inverter power supply, which board 30 is disposed in the lower part of the housing 9 at a distance from the housing walls, so that the cooling air flow can sweep both sides of the board. Due to the fluidic coupling of the flowing inside the housing 9 cooling air flows through the air outlet openings 19 and 20 to the suction sides of the two cooling air blower 7, 13 and by the presence of the aforementioned air guide is obtained at least two substantially mutually perpendicular exhaust air flows in the direction of arrows 31 in the direction the radial fan 7 and in the direction of arrow 32 in the direction of the cooling air blower 13, as in FIG. 1 clarified. The air outlet openings 20 in the form of hole groups are arranged in the upper part 9b of the housing 9, ie in the immediate vicinity of the suction side of the cooling air blower 13 and serve in particular for heat removal from the region of the power semiconductors and the high voltage transformer of the inverter power supply of the microwave device. At the bottom part of the molded part 9a of the housing 9 adjustable feet 33 are formed, with which the housing 9 with air clearance on the base plate 5 rests (see FIGS. 1 and 2 ). Due to this air gap 34 or gap can flow in the direction of arrow 35 cooling air and the underside of the housing 9, whereby the housing itself is forcibly cooled.
