Description

Hoch-Einbaugargerät High-cooking appliance
Die Erfindung bezieht sich auf ein Hoch-Einbaugargerät gemäß dem Oberbegriff des Patentanspruches 1.The invention relates to a high-level built-in cooking appliance according to the preamble of patent claim 1.
Als gattungsgemäßes Hoch-Einbaugargerät ist der aus der WO 98/04871 bekannte Wandofen in Betracht zu ziehen. Der Wandofen hat einen Garraum bzw. eine Ofenkammer, die von Seitenwänden, einer Front-, Rück- sowie Oberwand umgeben ist und eine bodenseitige Ofenkammeröffnung aufweist, wobei der Wandofen mit seiner Rückwand nach Art eines Hängeschranks an einer Wand zu befestigen ist. Die bodenseitige Ofenkammeröffnung ist mit einer absenkbaren Bodentür verschließbar. Auf der Oberseite der Bodentür ist eine Stützanordnung bzw. ein Halterungsteil für Backbleche und anderes Ofenzubehör gehaltert.The wall oven known from WO 98/04871 should be considered as a generic high-level built-in cooking appliance. The wall oven has a cooking chamber or an oven chamber which is surrounded by side walls, a front, rear and top wall and has a bottom-side oven chamber opening, the wall oven having its rear wall to be fastened to a wall in the manner of a wall cabinet. The bottom furnace chamber opening can be closed with a lowerable bottom door. A support arrangement or a holding part for baking trays and other oven accessories is held on the top of the base door.
Zum Verstellen der Bodentür weist der Wandofen eine Hubvorrichtung mit Hubelementen auf, die mit der Bodentür verbunden sind. Die Hubelemente sind als Gestängehebel ausgebildet, die zum einen im Innenraum der Ofenkammer an deren Innenwänden und zum anderen an dem auf der Bodentür befestigten Halterungsteil für Backbleche schwenkbar gelagert sind. Beim Verstellen der Bodentür sind die Gestängehebel parallel zu einer Ebene der Seitenwände der Ofenkammer verschwenkbar.To adjust the bottom door, the wall oven has a lifting device with lifting elements which are connected to the bottom door. The lifting elements are designed as linkage levers, which are pivotally mounted on the one hand in the interior of the oven chamber on their inner walls and on the other hand on the mounting part for baking trays fastened to the base door. When adjusting the bottom door, the linkage levers can be pivoted parallel to a plane of the side walls of the furnace chamber.
Eines der an den Seitenwänden der Ofenkammer gelagerten Enden der Gestängehebel ist drehfest mit einer Betätigungswelle verbunden. Diese Betätigungswelle ragt durch eine Seitenwand der Ofenkammer und kann von einem außerhalb der Ofenkammer angeordneten Antriebsmotor angetrieben werden. Bei Betätigung des Antriebsmotors lassen sich somit die Gestängehebel in einer Schwenkbewegung verstellen.One of the ends of the linkage levers mounted on the side walls of the furnace chamber is connected in a rotationally fixed manner to an actuating shaft. This actuating shaft protrudes through a side wall of the furnace chamber and can be driven by a drive motor arranged outside the furnace chamber. When the drive motor is actuated, the linkage levers can thus be adjusted in a pivoting movement.
Aufgrund ihrer Anordnung innerhalb der Ofenkammer sind die Hubelemente während des Betriebs nicht nur Verunreinigungen sondern auch starken Wärmebelastungen ausgesetzt, die die Funktionsfähigkeit der Hubelemente beeinträchtigen können. Die Hubelemente müssen daher derart aufwendig konstruiert werden, dass sie diesen Belastungen standhalten. Die Aufgabe der Erfindung besteht darin, ein Hoch-Einbaugargerät gemäß dem Oberbegriff des Patentanspruches 1 derart weiterzuentwickeln, dass seine Hubvorrichtung eine verbesserte Betriebssicherheit aufweist.Due to their arrangement within the furnace chamber, the lifting elements are not only exposed to contamination during operation, but also to strong thermal loads which can impair the functionality of the lifting elements. The lifting elements must therefore be constructed in such a complex manner that they can withstand these loads. The object of the invention is to further develop a high-level built-in cooking appliance in accordance with the preamble of claim 1 in such a way that its lifting device has improved operational reliability.
Erfindungsgemäß wird die Aufgabe durch die im Patentanspruch 1 angegebene Merkmalskombination gelöst. Gemäß dem kennzeichnenden Teil des Patentanspruches 1 ist die Hubvorrichtung mit ihren Hubelementen bei einem verschlossenen Garraum außerhalb des Garraums angeordnet. Erfindungsgemäß sind die Hubelemente der Hubvorrichtung während eines Garbetriebs des Hoch-Einbaugargeräts daher weder einer Wärmebelastung ausgesetzt noch werden die Hubelemente durch Gargut verschmutzt, wodurch die Betriebssicherheit der Hubvorrichtung in einfacher Weise verbessert ist. Somit ist erfindungsgemäß lediglich eine Gargutträgerhalteanordnung innerhalb des verschlossenen Garraums vorgesehen.According to the invention the object is achieved by the combination of features specified in claim 1. According to the characterizing part of patent claim 1, the lifting device with its lifting elements is arranged in a closed cooking space outside the cooking space. According to the invention, the lifting elements of the lifting device are therefore neither exposed to a thermal load during cooking operation of the high-level built-in cooking appliance nor are the lifting elements contaminated by food to be cooked, as a result of which the operational safety of the lifting device is improved in a simple manner. Thus, according to the invention, only one food holder arrangement is provided within the closed cooking space.
Um die thermische Belastung der Hubelemente während des Garbetriebs möglichst gering zu halten, ist zwischen der verschlossenen Bodentür und der bodenseitigen Muffel eine Dichtzone ausgebildet und sind die Hubelemente außerhalb dieser Dichtzone mit der Bodentür verbunden.In order to keep the thermal load on the lifting elements as low as possible during cooking operation, a sealing zone is formed between the closed base door and the base-side muffle and the lifting elements are connected to the base door outside of this sealing zone.
Gemäß einer Weiterentwicklung der Erfindung liegt bei verschlossenem Garraum die dem Garraum zugewandte Oberseite der Bodentür dem bodenseitigen Muffelrahmen der Muffel stirnseitig gegenüber. Dadurch kann die Bodentür beispielsweise mittels eines Antriebsmotors aktiv gegen den bodenseitigen Muffelrahmen gedrückt werden, so dass der verschlossene Garraum noch wirkungsvoller gegenüber den Hubelementen thermisch abgedichtet werden kann.According to a further development of the invention, when the cooking chamber is closed, the top side of the base door facing the cooking chamber is located opposite the muffle frame on the front side of the muffle. As a result, the base door can be actively pressed against the base-side muffle frame, for example by means of a drive motor, so that the closed cooking space can be thermally sealed even more effectively with respect to the lifting elements.
Diese thermische Abdichtung zwischen dem verschlossenen Garraum und den Hubelementen wird dadurch verstärkt, dass zwischen der Oberseite der verschlossenen Bodentür und dem bodenseitigen Muffelrahmen eine O-ringförmige Dichtung angeordnet wird. In diesem Zusammenhang ist es vorteilhaft, wenn die Oberseite der Bodentür mit einer wärmebeständigen Platte mit einem geringen Wärmeausdehnungskoeffizienten abgedeckt ist. Dadurch ist eine wärmebedingte Verformung bzw. Durchbiegung der Platte vermieden, so dass bei einem Garbetrieb mit verschlossener Bodentür eine dichtende Anlage der wärmebeständigen Platte an dem bodenseitigen Muffelrahmen gewährleistet ist. Um die wärmebeständige Platte fertigungstechnisch einfach auszuführen, ist es günstig, die Hubelemente außerhalb der wärmebeständigen Platte mit der Bodentür zu verbinden.This thermal seal between the closed cooking chamber and the lifting elements is reinforced by the fact that an O-ring-shaped seal is arranged between the top of the closed base door and the base-side muffle frame. In this context, it is advantageous if the top of the floor door is covered with a heat-resistant plate with a low coefficient of thermal expansion. This prevents heat-related deformation or deflection of the plate, so that, when cooking with closed bottom door, the heat-resistant plate is sealed against the muffle frame on the bottom is. In order to make the heat-resistant plate easy to manufacture, it is advantageous to connect the lifting elements outside the heat-resistant plate to the base door.
Eine stabile und konstruktiv einfache Ausführung der Hubelemente ergibt sich, wenn diese als starre L-förmige Träger sind, von denen jeder einen mit der Hubvorrichtung zusammenwirkenden senkrechten Schenkel und einen die Bodentür tragenden waagrechten Schenkel aufweist. Um einen ungehinderten Zugriff auf die Oberseite der abgesenkten Bodentür zu gewährleisten, greifen die waagrechten Schenkel der L- förmigen Träger im rückseitigen Bereich des Hoch-Einbaugargeräts in Tragabschnitte der Bodentür ein.A stable and structurally simple design of the lifting elements is obtained if they are in the form of rigid L-shaped supports, each of which has a vertical leg which interacts with the lifting device and a horizontal leg which supports the base door. In order to ensure unhindered access to the top of the lowered floor door, the horizontal legs of the L-shaped brackets engage in support sections of the floor door in the rear area of the built-in built-in cooking appliance.
Um die Bodentür in einfacher Weise zu verstellen, ist die Hubvorrichtung mit einem Antriebsmotor versehen, der mit den L-förmigen Trägern verbunden ist.In order to adjust the bottom door in a simple manner, the lifting device is provided with a drive motor which is connected to the L-shaped supports.

Um den Garraum 32 zu verschließen, ist die Bodentür 2 in die in der Figur 2 gezeigte Position zu verstellen. Zur Verstellung der Bodentür 2 weist das Hoch-Einbaugargerät eine Hubvorrichtung 3, 31 auf. Die Hubvorrichtung 3, 31 hat einen in den Figuren 1, 2 und 5 mit gestrichelten Linien dargestellten Antriebsmotor 31 , der zwischen der Muffel 21 und einer Außenwand des Gehäuses 38 angeordnet ist. Der Antriebsmotor 31 ist im Bereich der Rückseite des Gehäuses 38 angeordnet und ist, wie in der Figur 1 oder 5 gezeigt, in Wirkverbindung mit einem aus einem Paar von Hubelementen 3, die mit der Bodentür 2 verbunden sind. Dabei ist gemäß der schematischen Seitenansicht aus der Figur 5 jedes Hubelement 3 als ein L-förmiger Träger ausgestaltet. Der senkrechte Schenkel des L- förmigen Trägers 3 erstreckt sich ausgehend von dem gehäuseseitigen Antriebsmotor 31 durch Rahmenöffnungen 30 eines bodenseitigen Muffelrahmens 25 und kann in senkrechter Richtung in das Gehäuse 38 eingefahren bzw. aus dem Gehäuse 38 herausgefahren werden. Der waagrechte Schenkel des L-förmigen Trägers 3 greift in einen Tragabschnitt 40 der Bodentür 2, um die Bodentür 2 zu tragen. Ein solcher Tragabschnitt 40 ist an jeder Schmalseite der Bodentür 2 ausgebildet, wie in der Figur 6 dargelegt ist. Die Figur 6 stellt in perspektivischer Ansicht ein Formblech der Bodentür 2 sowie eine auf dem Formblech zu montierende Glaskeramikplatte 8 dar. Zur Formung der Tragabschnitte 40 obere Abschnitte der Seitenwände des Formblechs der Bodentür 2 um 90° aufeinander zu gebogen worden, so dass die waagrechten Schenkel der L-förmigen Träger 3 die Tragabschnitte 40 untergreifen können. Zum Verstellen der Bodentür 2 kann der Antriebsmotor 31 der Hubvorrichtung mit Hilfe eines Bedienknebels eines Bedienfelds einer Steuereinrichtung 34 betätigt werden, das gemäß den Figuren 1 und 2 frontseitig an der Bodentür 2 angeordnet ist.In order to close the cooking space 32, the base door 2 must be adjusted to the position shown in FIG. 2. The high built-in cooking appliance has a lifting device 3, 31 for adjusting the bottom door 2. The lifting device 3, 31 has a drive motor 31 shown in FIGS. 1, 2 and 5 with dashed lines, which is arranged between the muffle 21 and an outer wall of the housing 38. The drive motor 31 is arranged in the region of the rear of the housing 38 and, as shown in FIG. 1 or 5, is operatively connected to one of a pair of lifting elements 3 which are connected to the base door 2. According to the schematic side view from FIG. 5, each lifting element 3 is designed as an L-shaped carrier. The vertical leg of the L-shaped support 3 extends from the housing-side drive motor 31 through frame openings 30 of a base-side muffle frame 25 and can be inserted in the vertical direction into the housing 38 or removed from the housing 38. The horizontal leg of the L-shaped support 3 engages in a support section 40 of the base door 2 in order to support the base door 2. Such a support section 40 is formed on each narrow side of the base door 2, as shown in FIG. 6. FIG. 6 shows a perspective view of a shaped plate of the base door 2 and a glass ceramic plate 8 to be mounted on the shaped plate. To form the support sections 40, upper sections of the side walls of the shaped plate of the bottom door 2 have been bent towards one another by 90 °, so that the horizontal legs the L-shaped support 3 can reach under the support sections 40. To adjust the bottom door 2, the drive motor 31 of the lifting device can be actuated with the aid of an operating knob of a control panel of a control device 34, which is arranged on the front of the bottom door 2 according to FIGS. 1 and 2.
Der Figur 1 ist zu entnehmen, dass eine Oberseite der Bodentür 2 ein Kochfeld 10 aufweist. Nahezu die gesamte Fläche des Kochfelds 10 ist von Heizkörpern 5, 6, 7 eingenommen, die in Figur 1 strichpunktiert angedeutet ist. In Figur 1 sind die Heizkörper 5, 6 zwei voneinander beabstandete, verschieden große Kochstellenheizkörper, während der Heizkörper 7 ein zwischen den beiden Kochstellenheizkörpern 5, 6 vorgesehener Flächenheizkörper ist, dessen Seitenabschnitte 9 die Kochstellenheizkörper 5, 6 nahezu umschließen. Den Heizkörpern 5, 6, 7 sind jeweils Schaltorgane zugeordnet, die von der Steuereinrichtung 34 ansteuerbar sind, wie später beschrieben ist.It can be seen from FIG. 1 that an upper side of the base door 2 has a hob 10. Almost the entire surface of the cooktop 10 is occupied by radiators 5, 6, 7, which is indicated by dash-dotted lines in FIG. 1. In Figure 1, the radiators 5, 6 are two spaced-apart, different size hotplate radiators, while the heater 7 is a surface heater provided between the two hotplate radiators 5, 6, the side portions 9 of which almost surround the hotplate radiators 5, 6. The radiators 5, 6, 7 are each assigned switching elements which can be controlled by the control device 34, as will be described later.
In dem gezeigten Ausführungsbeispiel sind die Heizkörper 5, 6, 7 als Strahlungsheizkörper ausgestaltet, die von der Glaskeramikplatte 8 abgedeckt sind. Die in Figur 6 demontiert von der Bodentür 2 gezeigte Glaskeramikplatte 8 hat in etwa die Ausmaße der Oberseite der Bodentür 2. An ihren hinteren Ecken hat die Glaskeramikplatte 8 an ihrem Außenumfangsrand zwei Aussparungen 26, die die Öffnungen der Aufnahmen 40 teilweise umschließen können. Demnach sind die L- förmigen Träger 3 außerhalb der Glaskeramikplatte 8 mit der Bodentür 2 verbunden. Ferner hat die Glaskeramikplatte 8 noch Montageöffnungen 22, durch die später beschriebene Sockel 50 zur Halterung eines Halterungsteils 19 einer Gargutträgeranordnung 19, 51 ragen.In the exemplary embodiment shown, the radiators 5, 6, 7 are designed as radiant heaters which are covered by the glass ceramic plate 8. The glass ceramic plate 8 shown in FIG. 6 disassembled from the base door 2 has approximately the dimensions of the top of the base door 2. At its rear corners, the glass ceramic plate 8 has two cutouts 26 on its outer peripheral edge, which can partially enclose the openings of the receptacles 40. Accordingly, the L-shaped supports 3 are connected to the base door 2 outside the glass ceramic plate 8. Furthermore, the glass ceramic plate 8 also has mounting openings 22, through which the base 50, described later, for holding a holding part 19 of a food support arrangement 19, 51 protrude.
Gemäß der in der Figur 3 gezeigten vergrößerten Schnittansicht liegt die Oberseite der Bodentür 2 dem bodenseitigen Muffelrahmen 25 stirnseitig gegenüber. DieAccording to the enlarged sectional view shown in FIG. 3, the top of the base door 2 is located on the face side of the base-side muffle frame 25. The
Glaskeramikplatte 8 der Bodentür 2 ist in einem umfangsseitig verlaufenden ProfilrahmenGlass ceramic plate 8 of the base door 2 is in a profile frame running on the circumference
28 eines Formblechs der Bodentür 2 eingefasst. Zwischen der Glaskeramikplatte 8 und der Unterseite des Formblechs der Bodentür 2 ist ein Zwischenraum 41 ausgebildet, in dem die Strahlungsheizkörper 5, 6, 7 angeordnet sind. Zur Wärmeisolierung sind die Heizkörper 5, 6, 7 allesamt in einem Heizkörpergehäuse 24 aufgenommen, dessen Umfangsrand 44 mit einer Unterseite der Glaskeramikplatte 8 verbunden ist. Innerhalb des Heizkörpergehäuses 24 sind die Strahlungsheizkörper 5, 6, 7 auf einem Isolierkörper28 of a shaped sheet of the bottom door 2 edged. Between the glass ceramic plate 8 and the underside of the shaped plate of the base door 2, an intermediate space 41 is formed, in which the radiant heaters 5, 6, 7 are arranged. For heat insulation, the radiators 5, 6, 7 are all accommodated in a radiator housing 24, the peripheral edge 44 of which is connected to an underside of the glass ceramic plate 8. Within the radiator housing 24, the radiant heaters 5, 6, 7 are on an insulating body
29 gebettet. Darüber hinaus befinden sich im Zwischenraum 41 strichpunktiert angedeutete Funktionsteile, wie z. B. Elektronikbauteile der Steuereinrichtung 34. Diese Funktionsteile sind in einem Randbereich der Bodentür 2 angeordnet.29 bedded. In addition, there are dot-dash lines in the intermediate space 41 indicated functional parts, such as. B. Electronic components of the control device 34. These functional parts are arranged in an edge region of the base door 2.
Wie in der Figur 3 dargestellt, erstreckt sich das von den Heizkörpern 5, 6, 7 eingenommene Kochfeld 10 bis unmittelbar an den Bereich der Innenwand der Muffel 21. Dadurch wird eine weit ausgedehnte Fläche des Kochfelds 10 auf der Oberseite der Bodentür 2 erzielt. Aufgrund der geringen Wärmeleitfähigkeit der Glaskeramikplatte 8 fällt während eines Kochfeldbetriebs die Temperatur der Glaskeramikplatte 8 außerhalb des Kochfelds in der mit x gezeigten Richtung schnell ab. Eine übermäßig große Wärmeableitung in der Glaskeramikplatte in x-Richtung wird somit durch die geringe Wärmeleitfähigkeit der Glaskeramikplatte 8 vermieden.As shown in FIG. 3, the cooktop 10 occupied by the radiators 5, 6, 7 extends right up to the area of the inner wall of the muffle 21. A large area of the cooktop 10 on the upper side of the base door 2 is thereby achieved. Due to the low thermal conductivity of the glass ceramic plate 8, the temperature of the glass ceramic plate 8 drops rapidly outside the hob in the direction shown by x during hob operation. Excessively large heat dissipation in the glass ceramic plate in the x direction is thus avoided by the low thermal conductivity of the glass ceramic plate 8.
Der Figur 3 ist auch zu entnehmen, dass zwischen der Glaskeramikplatte 8 und dem Muffelrahmen 25 ist eine Dichtung 20 angeordnet ist. Die Dichtung 20 ist in nicht näher gezeigter Weise im Muffelrahmen 25 eingehängt und umzieht die Muffelöffnung 17 rahmenartig. Bei verschlossener Bodentür 2 entsteht somit zwischen dem bodenseitigen Muffelrahmen 25, der Dichtung 20 und der Glaskeramikplatte 8 eine Dichtzone 18. Innerhalb der Dichtzone 18 ist das Kochfeld 10 angeordnet, während der bereits erwähnte Randbereich der Glaskeramikplatte 8 außerhalb der Dichtzone 18 liegt. Der in x-Richtung außerhalb der Dichtzone 18 gelegene Randbereich der Glaskeramikplatte 8 ist daher äußerst wirkungsvoll thermisch gegenüber dem Garraum 32 entkoppelt. Dieser thermisch entkoppelte Randbereich der Glaskeramikplatte 8 erwärmt sich während eines Betriebs des Hoch-Einbaugargeräts bei verschlossener Bodentür 2 nur geringfügig, so dass außerhalb der Dichtungszone 18 ein Festbrennen von Gargut auf der Glaskeramikplatte 8 vermieden werden kann und Anwender vor hohen Temperaturen der Bodentür 2 geschützt werden können. Der reinigungskritische Randbereich der Glaskeramikplatte 8 ist daher nach einem Garbetrieb bequem zu reinigen.It can also be seen from FIG. 3 that a seal 20 is arranged between the glass ceramic plate 8 and the muffle frame 25. The seal 20 is suspended in a manner not shown in the muffle frame 25 and moves the muffle opening 17 like a frame. When the base door 2 is closed, a sealing zone 18 is thus created between the base-side muffle frame 25, the seal 20 and the glass ceramic plate 8. The hob 10 is arranged within the sealing zone 18, while the edge region of the glass ceramic plate 8 already mentioned lies outside the sealing zone 18. The edge region of the glass ceramic plate 8 located outside the sealing zone 18 in the x direction is therefore extremely effectively thermally decoupled from the cooking chamber 32. This thermally decoupled edge region of the glass ceramic plate 8 heats up only slightly during operation of the high-level built-in cooking appliance when the base door 2 is closed, so that cooking material on the glass ceramic plate 8 can be avoided outside the sealing zone 18 and users are protected from high temperatures of the base door 2 can. The cleaning-critical edge area of the glass ceramic plate 8 is therefore easy to clean after cooking.
Wie bereits oben erwähnt, ist an der Oberseite der Bodentür 2 die Gargutträgerhalteanordnung 19, 51 gehaltert, die bei verschlossener Bodentür 2 innerhalb des Garraums 32 angeordnet ist. Die Gargutträgerhalteanordnung weist gemäß der Figur 8 das Halterungsteil 19 zum Einhängen von Gargutträgern 58 und eine bodentürseitige Verankerung 51 auf. Im vorliegenden Ausführungsbeispiel besteht das Halterungsteil 19 aus zwei hohlzylindrischen Trägersäulen. In jeder der Trägersäulen 19 sind auf gleicher Höhe Freischnitte ausgebildet, in die gemäß Figur 8 der Gargutträger 58 eingehängt ist. Die Trägersäulen 19 sind im hinteren Bereich des Garraums 32 angeordnet, und zwar zwischen dem Kochfeld 10 und der gestrichelt angedeuteten Dichtzone 18.As already mentioned above, the food support holding arrangement 19, 51 is held on the upper side of the base door 2 and is arranged inside the cooking space 32 when the base door 2 is closed. According to FIG. 8, the food holder arrangement has the holding part 19 for hanging food holders 58 and an anchoring 51 on the bottom door. In the present exemplary embodiment, the holding part 19 consists of two hollow cylindrical support columns. In each of the support columns 19 are on the same Height free cuts are formed, in which, according to FIG. 8, the food support 58 is hooked. The support columns 19 are arranged in the rear area of the cooking space 32, specifically between the cooktop 10 and the sealing zone 18 indicated by dashed lines.
Mit Bezug auf die Figuren 6 und 7 wird nachfolgend die erfindungsgemäße Halterung der Trägersäulen 19 in den in der Bodentür 2 befestigten Verankerungen 51 erläutert. Jede der Verankerungen 51 besteht gemäß Figur 6 aus einem U-profilförmigen Formblech 52, dessen eine Seite an einer Innenwand der Bodentür befestigt ist. Zwischen den Schenkeln jedes U-profilförmigen Formblechs 52 ist ein hohlzylindrisches Lagerteil 55 eingesetzt. Jedes Längsende des Lagerteils 55 weist einen Abschnitt 57 mit reduziertem Durchmesser auf. Diese Abschnitte 57 sind in einander gegenüberliegende Öffnungen der Schenkel jedes U-profilförmigen Formblechs 52 gehaltert, wie es in Figur 7 dargestellt ist. Aus der Figur 7 ist auch ersichtlich, dass in jedem hohlzylindrischen Lagerteil ein zylindrischer Sockel 50 gelagert ist, der mittels einer Arretierungsschraube 59 in dem Lagerteil 55 fixierbar ist.With reference to FIGS. 6 and 7, the mounting of the support columns 19 according to the invention in the anchors 51 fastened in the base door 2 is explained below. According to FIG. 6, each of the anchors 51 consists of a U-shaped sheet 52, one side of which is fastened to an inner wall of the base door. A hollow cylindrical bearing part 55 is inserted between the legs of each U-shaped sheet metal 52. Each longitudinal end of the bearing part 55 has a section 57 with a reduced diameter. These sections 57 are held in mutually opposite openings of the legs of each U-shaped sheet 52, as shown in FIG. It can also be seen from FIG. 7 that a cylindrical base 50 is mounted in each hollow cylindrical bearing part and can be fixed in the bearing part 55 by means of a locking screw 59.
Das Hohlprofil jeder Trägersäule 19 ist gemäß der Figur 7 korrespondierend zu der Form des zylinderförmigen Sockels 50 derart ausgebildet, dass die Trägersäulen 19 in einer Lospassung auf jedem der Sockel 50 problemlos aufsteckbar sind. Die zylindrische Wand jeder Trägersäule weist ferner eine Aussparung 61 auf, die bei einem lagerichtigen Aufstecken der Trägersäule 19 auf dem Sockel 50 einen am Sockel ausgebildeten Positionierstift 53 des Sockels 50 aufnimmt.According to FIG. 7, the hollow profile of each support column 19 is designed corresponding to the shape of the cylindrical base 50 in such a way that the support columns 19 can easily be plugged onto each of the bases 50 in a loose fit. The cylindrical wall of each support column also has a recess 61 which, when the support column 19 is fitted in the correct position on the base 50, receives a positioning pin 53 of the base 50 which is formed on the base.
Zur Abdichtung der die Sockel 50 aufnehmenden Montageöffnungen 22 der Glaskeramikplatte 8 ist jeder Sockel 50 gemäß der Figur 7 an seinem Mittelbereich mit einem Ringflansch ausgebildet. Der Außendurchmesser des Ringflansches ist größer als der Durchmesser der Montageöffnung 22, so dass der Ringflansch des Sockels die Montageöffnung 22 überdeckt. Zwischen dem Ringflansch 51 und der Glaskeramikplatte 8 ist eine O-Ringdichtung 56 angeordnet. Bei in dem Lagerteil 55 montiertem Sockel 50 kann der Ringflansch über die O-Ringdichtung 51 eine gewisse Druckkraft auf die Glaskeramikplatte 8 ausüben, die auf dem als Widerlager dienenden Formblech 52 der Verankerung 51 aufliegt. Somit ist die Verankerung 51 sicher gegenüber der Glaskeramikplatte 8 abgedichtet. Der in Figur 8 gezeigte Gargutträger 58 ist an jeder seiner Schmalseiten mit einem Trägerteil 64 versehen, das unterhalb einer in der Figur 9 strichpunktiert angedeuteten waagrechten Umrandung des Gargutträgers 58 angeordnet ist. Gemäß der Figur 9 hat jedes Trägerteil 64 Lageransätze 65, 66. Beim Einhängen des Gargutträgers 58 in die Trägersäulen 19 werden zunächst die in Figur 9 gezeigten oberen Lageransätze 66 der Trägerteile 64 des Gargutträgers 58 in die fensterartigen Freischnitte eingeführt und mit einer Innenwand der Trägersäule 19 in Anlage gebracht, während die in Figur 9 gezeigten unteren Lageransätze 65 der Trägerteile 64 des Gargutträgers 58 mit einer Außenwand der Trägersäule in Anlage gebracht werden. Durch das auf die Lageransätze 65, 66 ausgeübte Drehmoment des Gargutträgers 58 verbleiben die Lageransätze 65, 66 in sicherer Anlage mit der Innen- und Außenwand der Trägersäulen 19.In order to seal the mounting openings 22 of the glass ceramic plate 8 receiving the base 50, each base 50 according to FIG. 7 is formed with an annular flange at its central region. The outer diameter of the ring flange is larger than the diameter of the mounting opening 22, so that the ring flange of the base covers the mounting opening 22. An O-ring seal 56 is arranged between the ring flange 51 and the glass ceramic plate 8. When the base 50 is mounted in the bearing part 55, the ring flange can exert a certain compressive force on the glass ceramic plate 8 via the O-ring seal 51, which rests on the shaped plate 52 of the anchor 51 serving as an abutment. The anchoring 51 is thus securely sealed off from the glass ceramic plate 8. The food support 58 shown in FIG. 8 is provided on each of its narrow sides with a support part 64 which is arranged below a horizontal border of the food support 58 indicated by dash-dotted lines in FIG. According to FIG. 9, each carrier part 64 has bearing projections 65, 66. When the food carrier 58 is suspended in the carrier columns 19, the upper bearing projections 66 of the carrier parts 64 of the food carrier 58 shown in FIG. 9 are first inserted into the window-like free cuts and with an inner wall of the carrier column 19 brought into contact, while the lower bearing lugs 65 of the support parts 64 of the food support 58 shown in FIG. 9 are brought into contact with an outer wall of the support column. Due to the torque of the food carrier 58 exerted on the bearing lugs 65, 66, the bearing lugs 65, 66 remain in secure contact with the inner and outer walls of the carrier columns 19.
Mit Hilfe eines im Bedienfeld der Steuereinrichtung 34 vorgesehenen Bedienknebels kann das Hoch-Einbaugargerät auf eine Kochstellen- oder eine Unterhitzebetriebsart geschaltet werden, die nachfolgend erläutert werden.With the help of a control knob provided in the control panel of the control device 34, the high-level built-in cooking appliance can be switched to a hotplate or a bottom heat operating mode, which are explained below.
In der Kochstellenbetriebsart können die Kochstellenheizkörper 5, 6 mittels Bedienknebeln, die im Bedienfeld der Steuereinrichtung 34 vorgesehen sind, individuell angesteuert werden, während der Flächenheizkörper 7 außer Betrieb bleibt. Die Kochstellenbetriebsart ist bei abgesenkter Bodentür 2 ausführbar, wie es in Figur 1 gezeigt ist. Sie kann aber auch bei verschlossenem Garraum 32 mit hochgefahrener Bodentür 2 in einer Energiesparfunktion betrieben werden.In the hotplate operating mode, the hotplate heating elements 5, 6 can be individually controlled by means of control knobs which are provided in the control panel of the control device 34, while the flat heating element 7 remains out of operation. The hob mode can be carried out with the bottom door 2 lowered, as shown in FIG. 1. However, it can also be operated in an energy-saving function when the cooking chamber 32 is closed with the base door 2 raised.
In der Unterhitzebetriebsart werden erfindungsgemäß von der Steuereinrichtung 34 nicht nur die Kochstellenheizkörper 5, 6 sondern auch der Flächenheizkörper 7 angesteuert. Darüber hinaus kann in der Unterhitzebetriebsart eine an einer Oberseite der Muffel 21 vorgesehene Oberhitzeheizkörper von der Steuereinrichtung 34 angesteuert werden,In the bottom heat mode, according to the invention, the control device 34 not only controls the hotplate heating elements 5, 6 but also the surface heating element 7. In addition, in the lower heat mode of operation, an upper heat radiator provided on an upper side of the muffle 21 can be controlled by the control device 34.
Um während des Unterhitzebetriebs ein möglichst gleichmäßiges Bräunungsbild des Garguts zu erreichen, ist entscheidend, dass das die Unterhitze bereitstellende Kochfeld 10 eine über die Fläche des Kochfelds 10 gleichmäßige Verteilung der Heizleistungsabgabe aufweist, obwohl die Heizkörper 5, 6, 7 verschiedene Nennleistungen aufweisen. Erfindungsgemäß werden daher die Heizkörper 5, 6, 7 von der Steuereinrichtung 34 nicht auf einen Dauerbetrieb geschaltet, sondern wird die Stromversorgung zu den Heizkörpern 5, 6, 7 mittels der von der Steuereinrichtung 34 gesteuerten Schaltorgane 11, 12, 13 getaktet. Dabei werden die unterschiedlich großen Nenn-Heizleistungen der Heizkörper 5, 6, 7 individuell so reduziert, dass die Heizkörper 5, 6, 7 eine über die Fläche des Kochfelds 10 gleichmäßige Verteilung der Heizleistungsabgabe verschaffen.In order to achieve the most uniform possible browning of the food to be cooked during the bottom heat mode, it is crucial that the hob 10 providing the bottom heat has a uniform distribution of the heating power output over the surface of the hob 10, although the radiators 5, 6, 7 have different nominal powers. According to the invention, the radiators 5, 6, 7 are therefore not switched to continuous operation by the control device 34, but rather are Power supply to the radiators 5, 6, 7 is clocked by means of the switching elements 11, 12, 13 controlled by the control device 34. The differently sized nominal heating outputs of the radiators 5, 6, 7 are individually reduced so that the radiators 5, 6, 7 provide a uniform distribution of the heating output over the surface of the hob 10.
Diese ausreichend gleichmäßig verteilte Heizleistungsabgabe kann mittels eines weiteren Bedienknebels der Steuereinrichtung 34 vom Anwender je nach Heizleistungsbedarf eingestellt werden. This sufficiently evenly distributed heat output can be set by the user by means of a further control knob of the control device 34 depending on the heating output requirement.
