Abstract
Description
Wärmegerät, insbesondere Backofen Warming device, especially an oven
Die Erfindung bezieht sich auf ein Wärmegerät mit einem durch eine Tür verschließbaren Behandlungsraum, insbesondere auf einen Backofen mit einer Einrichtung zur pyrolythi- schen Selbstreinigung, wobei zwischen der Türinnenseite und einem die Türöffnung des Behandlungsraumes umziehenden Geräteflansch ein aus unterschiedlich temperaturbeständigen Materialien bestehendes Dichtungselement vorgesehen ist, dessen höher temperaturbeständiger Teil dem Behandlungsraum zugewandt und dessen weniger temperaturbeständiger Teil dem Behandlungsraum abgewandt ist.The invention relates to a heating device with a treatment room that can be closed by a door, in particular to an oven with a device for pyrolytic self-cleaning, a sealing element consisting of different temperature-resistant materials being provided between the inside of the door and a device flange moving around the door opening of the treatment room. whose more temperature-resistant part faces the treatment room and whose less temperature-resistant part faces away from the treatment room.
Bei einem bekannten Backofen (WO02/44620A1), insbesondere mit Pyrolysebetrieb, ist zwischen einer Backofentür und dem Geräteflansch ein Dichtungselement angeordnet, das an dem kalten, dem Behandlungsraum abgewandten Bereich eines Backofenflansches anliegend angeordnet ist, ohne dass es den heißen, dem Behandlungsraum zuge- wandten Bereich kontaktiert. Das Befestigungselement kann aus zwei, aus unterschiedlich temperaturbeständigen Materialien bestehen, beispielsweise aus Silikonmaterial für den kälteren Bereich und aus Glasseidematerial für den thermisch höher beanspruchten Bereich. Um bei dem vorgenannten Backofen einen deutlichen Temperaturunterschied zwischen dem "heißen", dem Behandlungsraum zugewandten bzw. unmittelbar benach- barten Bereich und dem "kalten", von der Türöffnung des Behandlungsraumes entfernteren Bereich zu erreichen, sind diese Bereiche durch langlochartige Öffnungen im Backofenflansch thermisch voneinander entkoppelt.In a known oven (WO02 / 44620A1), in particular with pyrolysis operation, a sealing element is arranged between an oven door and the appliance flange, said sealing element being arranged adjacent to the cold area of an oven flange facing away from the treatment room, without the hot area facing the treatment room contacted area. The fastening element can consist of two differently temperature-resistant materials, for example silicone material for the colder area and glass silk material for the area subjected to higher thermal stress. In order to achieve a clear temperature difference in the aforementioned oven between the "hot" area facing or immediately adjacent to the treatment room and the "cold" area which is further away from the door opening of the treatment room, these areas are thermally separated from one another through slot-like openings in the oven flange decoupled.
Der vorliegenden Erfindung liegt die Aufgabe zugrunde, ein Gerät der eingangs genann- ten Art so zu verbessern, dass insbesondere für sehr hohe Einsatztemperaturen bis beispielsweise 400° C bei z. B. pyrolythisch selbstreinigenden Backöfen das Dichtungselement im Hinblick auf den äußeren, der Außenluft zugewandten und daher bei geöffneter Gerätetür sichtbaren Seite als auch bezüglich der inneren, dem Behandlungsraum zugewandten Seite thermisch gegeneinander abgegrenzt sind, d. h. dazwischen kein wesentli- eher Wärmeaustausch stattfindet und dass beide vorgenannten peripheren Seiten auch nach langer Gebrauchsdauer sauber erscheinende bzw. leicht reinigbare Oberflächen darbieten.The object of the present invention is to improve a device of the type mentioned at the outset in such a way that, in particular for very high operating temperatures up to, for example, 400.degree. B. pyrolytically self-cleaning ovens, the sealing element with respect to the outer, the outside air and therefore visible when the appliance door is open and also with respect to the inner, the treatment room side are thermally delimited from each other, d. H. there is no significant heat exchange between them and that both of the aforementioned peripheral sides present surfaces which appear clean or are easy to clean even after a long period of use.
Diese Aufgabe wird bei einem Wärmegerät der eingangs genannten Art dadurch gelöst, dass zumindest die dem Behandlungsraum zugewandten inneren und die hiervon abge- wandten, äußeren Teile des Dichtungselementes aus gleichartigen, eine verschlossene, dichte Oberfläche aufweisenden Materialien bestehen.In a heating device of the type mentioned at the outset, this object is achieved in that at least the inner and the inner side facing the treatment room turned, outer parts of the sealing element consist of similar, a closed, dense surface materials.
Die erfindungsgemäße Lösung ermöglicht ein geschlossenporiges, flexibles, elastisches und wirtschaftlich vorteilhaftes Dichtungselement, das insbesondere geeignet ist für sehr hohe Einsatztemperaturen im Behandlungsraum von beispielsweise bis 400° C. Hierbei erhält man an den wenigstens beiden nach innen und außen offenen Seiten des Dichtungselementes eine luftdichte und glatte, d. h. auch reinigungsfreundliche Oberfläche, wobei diese entgegengesetzten Oberflächen thermisch gegeneinander abgegrenzt sind, so dass dazwischen kein wesentlicher Wärmeaustausch z. B. infolge Luftdurchlässigkeit stattfinden kann.The solution according to the invention enables a closed-pore, flexible, elastic and economically advantageous sealing element which is particularly suitable for very high operating temperatures in the treatment room of, for example, up to 400 ° C. In this case, an airtight and airtight seal is obtained on the at least two sides of the sealing element which are open inwards and outwards smooth, d. H. also easy to clean surface, these opposite surfaces are thermally delimited from each other, so that no significant heat exchange z. B. can take place due to air permeability.
Gemäß einer bevorzugten Ausgestaltung der Erfindung bestehen die Teile des Dichtungselementes aus unterschiedlich temperaturbeständigem Elastomer, insbesondere aus unterschiedlichen Silikonmaterialien, die vorzugsweise stoffschlüssig miteinander verbunden sind.According to a preferred embodiment of the invention, the parts of the sealing element consist of elastomer of different temperatures, in particular of different silicone materials, which are preferably integrally connected to one another.
In vorteilhafter Weise wird ein insbesondere durch Wärmeleitung hervorgerufener Wärmeaustausch zwischen den Teilen dadurch weitestgehend verhindert, dass die wenigs- tens zwei Teile nur an querschnittsarmen Bereichen miteinander verbunden sind, wobei es sich als besonders vorteilhaft erweist, wenn diese Teile in Form von zumindest einseitig offenen Hohlprofilen ausgebildet und an den querschnittsarmen Profilrändern miteinander verbunden sind.Advantageously, heat exchange between the parts, in particular caused by heat conduction, is largely prevented by the fact that the at least two parts are connected to one another only in regions with little cross-section, it proving to be particularly advantageous if these parts are in the form of hollow profiles which are open on at least one side trained and connected to each other at the low-profile profile edges.
Die Erfindung ist anhand von in der Zeichnung dargestellten Ausführungsbeispielen nachstehend erläutert.The invention is explained below with reference to exemplary embodiments shown in the drawing.
Es zeigt:It shows:
Figur 1 die Frontansicht eines als Backofen ausgeführten Wärmegerätes der erfindungsgemäßen Bauweise,FIG. 1 shows the front view of a heating device of the design according to the invention designed as an oven,
Figur 2 und 3 Querschnittsdarstellungen von unterschiedlich ausgestalteten Dichtungselementen in vergrößerter Ansicht. Bei dem Backofen 1 in Figur 1 ist innerhalb eines Gerätegehäuses 2 eine im wesentlichen quaderförmige Backofenmuffel 3 angeordnet, die einen Behandlungsraum 4 begrenzt. Der Behandlungsraum 4 wird umzogen von einem Geräteflansch 5, in welchem langloch- artige Schlitze 6 eingearbeitet sind, die den Geräteflansch 5 umziehen, wobei in Figur 1 nur wenige solcher Schlitze 6 dargestellt sind. Diese Schlitze 6 sollen den dem Behandlungsraum 4 zugewandten Abschnitt des Geräteflansches 5 thermisch entkoppeln von demjenigen Abschnitt des Geräteflansches 5, der weiter entfernt ist vom Behandlungsraum 5 bzw. seiner frontseitigen Öffnung. In Höhe dieser Schlitze 6 ist vorzugsweise an der Gerätefrontseite, also dem Geräteflansch 5, ein Dichtungselement 7 unter Zuhilfe- nähme der vorgenannten Schlitze 6 befestigt, das anhand der Figuren 2 und 3 näher verdeutlicht ist. Dieses Dichtungselement 7 befindet sich also unmittelbar benachbart der Türöffnung 8 des Behandlungsraumes 4, welche Türöffnung 8 dicht verschließbar ist durch eine in Figur 1 strichpunktiert angedeutete Tür 9, die beispielsweise um eine untere Drehachse schwenkbar ist und aus einer Schließstellung gemäß Figur 1 in eine Öff- nungsstellung verschwenkbar ist. Bei Betrieb des Backofens 1 ist die Tür 9 verschlossen und liegt mit Vorspannung an der äußeren Begrenzung des Dichtungselementes 7 an, so dass die im Behandlungsraum 4 vorhandene Wärmeenergie nicht wesentlich nach außen hin entkommen kann. In Figur 1 ist angedeutet, dass oberhalb des Behandlungsraumes 4 sich ein Bedientableau 10 befindet mit für den Betrieb des Backofens 1 notwendigen Be- dienorganen 11 und Anzeigeelementen 12.Figures 2 and 3 cross-sectional representations of differently designed sealing elements in an enlarged view. In the oven 1 in FIG. 1, an essentially cuboid oven muffle 3 is arranged within an appliance housing 2 and delimits a treatment room 4. The treatment room 4 is surrounded by a device flange 5, in which slots 6 are incorporated, which move the device flange 5, only a few such slots 6 being shown in FIG. These slots 6 are intended to thermally decouple the section of the device flange 5 facing the treatment room 4 from that section of the device flange 5 which is further away from the treatment room 5 or its front opening. At the level of these slots 6, a sealing element 7 is preferably attached to the front of the device, that is to say the device flange 5, with the aid of the aforementioned slots 6, which is illustrated in more detail with reference to FIGS. 2 and 3. This sealing element 7 is thus located directly adjacent to the door opening 8 of the treatment room 4, which door opening 8 can be closed tightly by a door 9 indicated by dash-dotted lines in FIG. position is pivotable. When the oven 1 is in operation, the door 9 is closed and bears against the outer boundary of the sealing element 7 with a prestress, so that the thermal energy present in the treatment room 4 cannot escape significantly to the outside. It is indicated in FIG. 1 that an operating panel 10 with operating elements 11 and display elements 12 necessary for the operation of the oven 1 is located above the treatment room 4.
Figur 2 zeigt eine vergrößerte Schnittansicht gemäß der Schnittlinie ll-ll in Figur 1. Hierbei ist ein Teil der Backofenmuffel 3 sowie ein Teil des die Türöffnung 8 umziehenden Geräteflansches 5 dargestellt. Wie erwähnt befinden sich in diesem Geräteflansch 5 die anei- nandergereihten Schlitze 6, gebildet durch Materialeinziehungen. Mit 9 ist wiederum die Tür angedeutet, die z. B. aus einer oder mehreren Glasplatten besteht und deren Türinnenseite 13 dem Behandlungsraum 4 zugewandt ist. In Figur 2 ist sehr deutlich das Querschnittsprofil des allgemein mit 7 bezeichneten Dichtungselementes gezeigt. Beim Ausführungsbeispiel gemäß Figur 2 besteht dieses Dichtungselement 7 aus zwei Teilen 14 und 15, die im wesentlichen als einseitig offene Hohlprofile ausgebildet sind und an den querschnittsarmen Profilrändern 14.1 und 15.1 stoffschlüssig, z. B. durch Koextrusion, Verkleben oder aber in einem Spritzgießverfahren miteinander verbunden sind. Hierbei besteht der Teil 14 des Dichtungselementes 7 aus einem hoch temperaturbeständigen Material, da dieser innere Teil 14 unmittelbar dem heißen Behandlungsraum 4 zugewandt ist, während der äußere Teil 15 sich im äußeren, etwas kühleren Bereich des Geräteflan- sches 5 befindet und insofern dem Behandlungsraum 4 abgewandt ist. Dieser Teil 15 besteht daher aus einem gegenüber dem Teil 14 weniger temperaturbeständigen Material. Beide Teile 14 und 15 bestehen jedoch aus gleichartigem, jeweils eine verschlossene, dichte Oberfläche aufweisenden Material, vorzugsweise aus unterschiedlich temperatur- beständigem Elastomer, insbesondere aus unterschiedlichen Silikonmaterialien. Dieses Material besitzt eine sehr dichte, luftundurchlässige und sehr glatte und daher reinigungsfreundliche bzw. schmutzabweisende Oberfläche. An dem dem Geräteflansch 5 zugewandten Teil des Dichtungselementes 7 befestigt in eine z. B. metallische Spreizklammer 16, wobei solche Spreizklammern 16 z. B. in regelmäßigen Abständen im Verlauf des Dichtungselementes 7 vorgesehen sind, welche Spreizklammern in die Schlitze 6 eingedrückt werden und darin verrasten und damit das Dichtungselement 7 am Geräteflansch 5 fixieren. An dem äußeren Teil 15 sind an gegenüberliegenden Begrenzungen nach außen abstehende flügelartige Dichtungsprofile 17 und 18 angeformt, die das gesamte Dichtungselement 7 umziehen. Das Dichtungsprofil 18 legt sich mit der Montage des Dich- tungselementes 7 am Geräteflansch 5 elastisch an den vorgenannten Geräteflansch 5 an, wie Figur 2 zeigt. Beim Verschließen der Tür 9 legt sich das andere Dichtungsprofil 17 ebenfalls elastisch an der Türinnenseite 13 der Tür 9 an und wird aus der in Figur 2 gezeigten Stellung nachjnnen leicht verformt.FIG. 2 shows an enlarged sectional view along the section line II-II in FIG. 1. Here, part of the oven muffle 3 and part of the appliance flange 5 moving around the door opening 8 are shown. As mentioned, in this device flange 5 there are the slots 6 lined up, formed by material insertions. With 9 again the door is indicated, the z. B. consists of one or more glass plates and the door inside 13 facing the treatment room 4. In Figure 2, the cross-sectional profile of the sealing element generally designated 7 is shown very clearly. In the exemplary embodiment according to FIG. 2, this sealing element 7 consists of two parts 14 and 15, which are essentially designed as hollow profiles that are open on one side and are integrally bonded to the cross-section-poor profile edges 14.1 and 15.1, for. B. are connected by coextrusion, gluing or in an injection molding process. The part 14 of the sealing element 7 consists of a highly temperature-resistant material, since this inner part 14 faces directly the hot treatment room 4, while the outer part 15 is located in the outer, somewhat cooler area of the device flange. 5 is located and in this respect facing away from the treatment room 4. This part 15 therefore consists of a material which is less temperature-resistant than the part 14. However, both parts 14 and 15 consist of the same type of material, each with a closed, dense surface, preferably of differently temperature-resistant elastomer, in particular of different silicone materials. This material has a very dense, air-impermeable and very smooth and therefore easy to clean or dirt-repellent surface. On the device flange 5 facing part of the sealing element 7 attached in a z. B. metallic spreading clamp 16, such spreading clamps 16 z. B. are provided at regular intervals in the course of the sealing element 7, which spreading clamps are pressed into the slots 6 and lock therein and thus fix the sealing element 7 on the device flange 5. On the outer part 15, wing-like sealing profiles 17 and 18 projecting outwards are formed at opposite boundaries and move the entire sealing element 7. When the sealing element 7 is mounted on the device flange 5, the sealing profile 18 rests elastically on the aforementioned device flange 5, as shown in FIG. 2. When the door 9 is closed, the other sealing profile 17 also rests elastically on the inside 13 of the door 9 and is slightly deformed from the position shown in FIG. 2.
Aufgrund der erfindungsgemäßen Ausgestaltung des Dichtungselementes 7 befindet sich der höher temperaturbeständige Teil 14 des Dichtungselementes 7 in unmittelbarer Nähe der Türöffnung 8 und ist aus einem Material gefertigt, das hohe Temperaturen bis beispielsweise 400° C aushält. Dagegen befindet sich der Teil 15 des Dichtungselementes 7 im "kälteren" Bereich des Geräteflansches 5 und braucht daher einer derart hohen vorge- nannten Temperatur nicht gewachsen sein. Dieses Material kann also wesentlich kostengünstiger sein als das Material des Teiles 14. In beiden Fällen handelt es sich um Materialien, die dicht und luftundurchlässig und dabei flexibel und elastisch sind, so dass ein solches zwei- oder mehrteiliges Dichtungselement 7 problemlos der rechteckförmigen Kontur der Türöffnung 8 folgend verlegt werden kann.Due to the configuration of the sealing element 7 according to the invention, the higher temperature-resistant part 14 of the sealing element 7 is located in the immediate vicinity of the door opening 8 and is made of a material that can withstand high temperatures of up to 400 ° C., for example. In contrast, part 15 of sealing element 7 is located in the “colder” area of device flange 5 and therefore does not need to be able to withstand such a high temperature. This material can therefore be considerably less expensive than the material of the part 14. In both cases, these are materials that are tight and air-impermeable and at the same time flexible and elastic, so that such a two-part or multi-part sealing element 7 easily matches the rectangular contour of the door opening 8 can be installed as follows.
Beim Ausführungsbeispiel gemäß Figur 3 ist ein Dichtungselement T im Querschnittsprofil gezeigt, welches Dichtungselement 7' zum Unterschied zum Ausführungsbeispiel gemäß Figur 2 an beiden Teilen 14' und 15' mit flügelartig abstehenden Dichtungsprofilen z. B. 17' und 18' versehen ist. Auch diese Teile 14' und 15' sind als Hohlprofile ausgebildet und an querschnittsarmen Rändern entlang der strichpunktierten Trennlinie stoffschlüssig miteinander verbunden.In the exemplary embodiment according to FIG. 3, a sealing element T is shown in the cross-sectional profile, which sealing element 7 'differs from the exemplary embodiment according to FIG. 2 on both parts 14' and 15 'with wing-like protruding sealing profiles e.g. B. 17 'and 18' is provided. These parts 14 'and 15' are also designed as hollow profiles and Cohesively connected to one another at cross-section margins along the dash-dotted dividing line.
Wie schon erwähnt, bestehen die beiden Teile 14, 15 bzw. 14', 15' des Dichtungselementes 7, 7' aus unterschiedlich temperaturbeständigem Material, vorzugsweise aus Silikonmaterialien, wobei das Material des inneren Teiles 14 entsprechend einer hohen Temperatur von z. B. 400° C ausgewählt ist, während der dem Behandlungsraum 4 abgewandte Teil 15, 15' aus einem minder temperaturbeständigen Silikonmaterial besteht, das z. B. nur bis zu einer Temperatur von z. B. 280° C ausgelegt ist. As already mentioned, the two parts 14, 15 and 14 ', 15' of the sealing element 7, 7 'are made of differently temperature-resistant material, preferably of silicone materials, the material of the inner part 14 corresponding to a high temperature of e.g. B. 400 ° C is selected, while the treatment room 4 facing away from part 15, 15 'consists of a less temperature-resistant silicone material, the z. B. only up to a temperature of z. B. 280 ° C is designed.
