Description
Die vorliegende Erfindung betrifft einen Elektrobackofen mit einer durch eine Tür verschließbaren Backofenmuffel, in der an einem Halterungselement ein Gargutträger halterbar ist, der ein eigenes Gargutträgerheizelement aufweist, und mit einem Stromzufuhrelement, über das das Gargutträgerheizelement mit der elektrischen Spannung des Backofens speisbar ist.The present invention relates to an electric oven with a lockable by a door Oven muffle in which a food support on a holding element can be held, which has its own food support heating element, and with a power supply element, via which the food support heating element with the electrical voltage the oven is feedable.
Ein derartiger Elektrobackofen ist bekannt aus der Druckschrift G 85 32 629.1, wobei der Gargutträger in unterschiedlichen Höhen an seitlichen Führungen der Backofenmuffel eingeschoben werden kann. In der Rückwandung der Backofenmuffel sind in unterschiedlichen Höhen, die denen der seitlichen Führungen entsprechen, jeweils elektrische Steckbuchsen vorgesehen. Die Heizeinrichtung für den Gargutträger besteht dabei aus einem Flächenheizelement, das an der Unterseite des Gargutträgerbodens angeordnet ist.Such an electric oven is known from the document G 85 32 629.1, wherein the food support at different heights on the side guides of the oven muffle can be inserted. In the back wall of the oven muffle are in different heights, which correspond to those of the side guides, each electrical sockets provided. The heating device for the food support exists thereby from a surface heating element on the underside of the food support base is arranged.
Aufgabe der vorliegenden Erfindung ist es, bei einem Elektrobackofen nach dem Oberbegriff des Patentanspruches 1 den Aufwand für die Kontaktierung des Gargutträgerheizelementes zu verringern.The object of the present invention is in an electric oven according to the Preamble of claim 1 the effort for contacting the food support heating element to reduce.
Erfindungsgemäß ist dies bei einem Elektrobackofen nach dem Oberbegriff des Patentanspruches 1 dadurch erreicht, daß das Halterungselement für den Gargutträger zugleich als das Stromzufuhrelement für das Gargutträgerheizelement dient. Die Integration sowohl der Halterungs- als auch der Stromzufuhrfunktion in ein Element führt zu einer Vereinfachung des Aufbaus des Elektrobackofens.This is according to the invention in an electric oven according to the preamble of the claim 1 achieved in that the holding element for the food support also serves as the power supply element for the food support heating element. The integration leads both the bracket and the power supply function in one element to simplify the construction of the electric oven.
Beispielsweise können an sich bekannte Einhängegitter bzw. Traggestelle, wie sie beispielsweise in der Druckschrift DE 42 43 364 A1 offenbart sind, im Backraum verschiebbar geführte Gestellwägen, wie sie beispielsweise in der Druckschrift DE 42 36 740 A1 offenbart sind, und die Rillen an sich bekannter Rillenbackrohre erfindungsgemäß gestaltet werden. Die an den gegenüberliegenden Seitenwänden der Backofenmuffel eingehängten beiden metallischen Traggestelle ragen beispielsweise mit Kontaktendabschnitten durch entsprechende Öffnungen der Muffelwand aus dieser. Die Kontaktendabschnitte der Traggestelle werden mit der Versorgungsspannung des Backofens verbunden. Zugleich ist das Traggestell gegenüber der Muffelwand elektrisch isoliert. Der in verschiedenen Höhen einschiebbare eigenbeheizte Gargutträger liegt mit seinem um das Gargut erhöhten Eigengewicht beispielsweise auf den Führungsstangen des metallischen Tragegestells. Dabei wird das Gargutträgerheizelement über entsprechende Anschlußstellen des Heizelementes durch den Kontakt mit dem metallischen Traggestell an die elektrische Versorgungsspannung des Backofens gelegt.For example, known hook-in grids or support frames, such as those are disclosed in the publication DE 42 43 364 A1, displaceable in the baking chamber guided rack carts, such as those described in DE 42 36 740 A1 are disclosed, and the grooves per se known groove baking tubes according to the invention be designed. The one on the opposite side walls of the oven muffle suspended two metallic support frames protrude, for example, with contact end sections through corresponding openings in the muffle wall. The Contact end sections of the support frames are connected to the supply voltage of the Oven connected. At the same time, the support frame is electrical opposite the muffle wall isolated. The self-heated food rack that can be inserted at different heights lies, for example, on the guide rods with its own weight increased by the food to be cooked of the metallic support frame. The food support heating element via corresponding connection points of the heating element through contact with the metal support frame to the electrical supply voltage of the oven placed.
Alternativ ist es auch möglich, daß ein metallischer Gestellwagen an seinem der Rückwand zugewandten Endabschnitt beispielsweise ein an den beiden Seitenbereichen des Wagens angeordnetes Steckerpaar aufweist. Beim Einschieben des Gestellwagens in die Muffel wird das Steckerpaar in ein an der Rückwand der Backofenmuffel vorgesehenes elektrisches Steckbuchsenpaar gesteckt, das an Netzspannung gelegt ist. Wichtig dabei ist, das der linke Teil des Gestellwagens vom rechten Teil elektrisch isoliert ist, um ein Kurzschließen der Versorgungsspannung durch den Gestellwagen zu vermeiden. Durch Einlegen eines Gargutträgers in den Gestellwagen, wird das Gargutträgerheizelement unter Beachtung der relevanten Sicherheitsvorschriften an die am Gestellwagen anliegende Versorgungsspannung angeschlossen.Alternatively, it is also possible that a metallic rack carriage on its End wall facing end section, for example, one on the two side areas of the carriage arranged plug pair. When inserting the rack trolley The pair of plugs is inserted into the muffle on the back wall of the oven muffle provided electrical socket pair plugged in, the mains voltage is laid. It is important that the left part of the frame carriage from the right part is electrically isolated to short-circuit the supply voltage through the rack to avoid. By inserting a food rack in the rack, becomes the food support heating element in compliance with the relevant safety regulations connected to the supply voltage on the rack trolley.
Weiterhin ist es auch möglich, daß auf den in den Seitenwänden einer Backofenmuffel ausgebildeten Rillen, die zum beidseitigen Führen und Haltern von Gargutträgern in an sich bekannter Weise dienen, elektrisch leitende Kontaktflächen vorgesehen sind. Beim Einschieben beispielsweise eines Backblechs in die gegenüberliegenden Rillen der Muffel wird das Gargutträgerheizelement insbesondere aufgrund des um das Gargut vergrößerten Gewichtes des Gargutträgers mit seinen Kontaktstellen auf die entsprechenden Kontaktstellen der Rillen gedrückt. Diese sind von der Muffelwand isoliert und an die elektrische Spannung des Backofens gelegt. Dadurch ist das Gargutträgerheizelement an die Versorgungsspannung des Backofens gelegt.Furthermore, it is also possible that in the side walls of an oven muffle Trained grooves for guiding and holding food carriers in on both sides serve in a known manner, electrically conductive contact surfaces are provided. When inserting a baking sheet, for example, into the opposite grooves the muffle becomes the food support heating element, in particular because of the food to be cooked increased weight of the food support with its contact points on the corresponding Contact points of the grooves pressed. These are isolated from the muffle wall and connected to the electrical voltage of the oven. This makes the food support heating element connected to the supply voltage of the oven.
Konstruktiv besonders einfach ist es, wenn als das Halterungselement zwei bei Backöfen mit sogenannten Backwägen bekannte Hakenschienen vorgesehen sind. Insbesondere ist dabei vorteilhaft, daß die elektrische Isolation der Hakenschienen vom Backofen einfach durchführbar ist, und daß aufgrund des Einhängens des Gargutträgers in die Hakenschienen die dabei auftretenden Drehmomente zu großen Andruckkräften und damit zu einem sicheren Kontakt zwischen den Anschlußelementen des Gargutträgerheizelementes und den unter elektrischer Spannung stehenden Hakenschienen sorgen.It is structurally particularly simple if two as the mounting element in ovens known hook rails are provided with so-called baking trolleys. In particular it is advantageous that the electrical insulation of the hook rails from Oven is easy to carry out, and that due to the hanging of the food support the resulting torques in the hook rails to great pressure forces and thus to a safe contact between the connection elements of the Food support heating element and the hook rails under electrical voltage to care.
Die Zugänglichkeit des Gargutes bzw. der Gargutträger ist besonders günstig, wenn das Halterungselement an der Innenseite der Backofentür befestigt ist. Weiterhin kann dadurch eine Funktionsprüfung bzw. eine elektrische Sicherheitsprüfung auf besonders einfache Weise durchgeführt werden. Alternativ können beispielsweise die beiden Hakenschienen auch an einem Luftleitblech gehaltert sein, das bei Elektrobacköfen mit Umluftbetrieb in an sich bekannter Weise im Bereich der Rückwand der Muffel angeordnet ist. Um die Zugänglichkeit des Gargutes bzw. der Gargutträger zu erhöhen, ist das Luftleitbleich entsprechend einem Gestellwagen in der Muffel verschiebbar geführt.The accessibility of the food to be cooked or the food support is particularly favorable if the bracket is attached to the inside of the oven door. Furthermore can thereby a functional test or an electrical safety test for special can be done easily. Alternatively, for example, the two Hook rails can also be held on an air baffle that is used in electric ovens Recirculation mode is arranged in a manner known per se in the area of the rear wall of the muffle is. To increase the accessibility of the food to be cooked or the food support, is the air bleach is guided according to a rack carriage in the muffle.
Zur Erhöhung der elektrischen Sicherheit weist der Backofen einen Türschalter und einen Betriebsschalter auf, die gemeinsam im Stromversorgungskreis des Stromzufuhrelementes liegen. Nur wenn der Betriebsschalter betätigt ist und zugleich die Tür des Backofens ordnungsgemäß geschlossen ist, wird das Halterungselement an die Netzspannung gelegt. Dadurch ist ein direktes Berühren von unter Spannung stehenden Teilen durch eine Bedienperson ausgeschlossen.To increase electrical safety, the oven has a door switch and one Operation switch on, together in the power supply circuit of the power supply element lie. Only if the operating switch is pressed and the door of the Oven is properly closed, the bracket element is connected to the mains voltage placed. This is a direct touch of live voltage Excluded by an operator.
Nachfolgend sind anhand schematischer Darstellungen zwei Ausführungsbeispiele des erfindungsgemäßen Backofens bzw. des erfindungsgemäßen Gargutträgers beschrieben.Below are two exemplary embodiments of the described oven or the food support according to the invention described.
Es zeigen:
- Fig. 1
- in einer perspektivischen Darstellung abschnittsweise ein erstes Ausführungsbeispiel und
- Fig. 2
- in vergrößertem Maßstab stark vereinfacht und abschnittsweise dargestellt ein zweites Ausführungsbeispiel.
- Fig. 1
- in a perspective representation in sections of a first embodiment and
- Fig. 2
- greatly simplified on an enlarged scale and shown in sections a second embodiment.
Gemäß dem ersten Ausführungsbeispiel ist ein elektrischer Backofen 1 mit einem
quaderförmigen Backraum 3 durch eine Ofentür 5 frontseitig verschließbar (Fig. 1).
Dabei ist die Ofentür 5 in Form eines verschiebbaren Backwagens ausgebildet. Eine
an sich bekannte Frontplatte der Ofentür 5 ist zusammen mit einem Türgriff an einem
an sich bekannten metallischen Türboden befestigt. Starr mit der Backofentür 5 sind
an deren unterem Endabschnitt ein paar horizontale Schiebezüge 6 verbunden, von
denen jeder entsprechend der Offenbarung der Druckschrift DE 40 23 949 A1 ausgebildet
und im Backofen 1 in an sich bekannter Weise geführt ist. An der Innenseite der
Ofentür 5 ist in den beiden Seitenabschnitten jeweils eine metallische Hakenschiene 7
befestigt. Diese erstreckt sich im wesentlichen über die gesamte Höhe der Ofentür 5
und weist im Ausführungsbeispiel gemäß Figur 1 vier übereinander liegende Haken
auf. Die Hakenschienen 7 sind elektrisch von der Ofentür 5 isoliert und sind über in
bzw. unterhalb der Tür 5 geführten elektrische Leitungen 8 (unterbrochene Linie) an
die Versorgungsspannung (nicht gezeigt) des Backofens 1 angeschlossen. Zum Bakken
sind in den Backraum 3 Backbleche 9 bringbar. Dabei wird das Backblech 9 mit
seinem Backblechflansch 11 auf einen metallischen Tragrahmen 13 gelegt. Der Tragrahmen
13 ist derart in die beiden Hakenschienen 7 eingehängt, daß er ein sich horizontal
rahmenförmig erstreckendes, stabiles Auflager bildet. Zusätzlich sind die beiden
Seitenbereiche des Tragrahmens 13 elektrisch voneinander isoliert, um ein Kurzschließen
der Versorgungsspannung durch den Tragrahmen 13 zu vermeiden. Durch
die mechanische Verbindung mit den Hakenschienen 7 kann der Tragrahmen 13 aus
Sicherheitsgründen lediglich dann an die Versorgungsspannung des Backofens 1 gelegt
werden, wenn die Ofentür 5 geschlossen und zugleich der Backofen 1 eingeschaltet
ist. Durch das Auflegen des Backblechs 9 auf den Tragrahmen 13 ist weiterhin ein
an der Unterseite des Backbleches 9 aufgebrachtes, mäanderförmig verlaufendes
Dickschichtheizelement 15 (in unterbrochenen Linien dargestellt) mit der Versorgungsspannung
verbindbar. Dabei fließt der Heizstrom durch die Leitungen 8 über die Hakenschiene
7 zum Tragrahmen 13 und über entsprechende Anschlußpads 17 des
Heizelementes 15 zu diesem (Fig. 1). According to the first embodiment, an electric oven 1 with a
cuboid baking chamber 3 can be closed from the front by an oven door 5 (FIG. 1).
The
Bei dem in Fig. 2 dargestellten zweiten Ausführungsbeispiel sind aus Gründen der
Vereinfachung im wesentlichen die Bezugszeichen des in Fig. 1 dargestellten ersten
Ausführungsbeispiels unverändert übernommen. Weiterhin sind aus Vereinfachungsgründen
in Fig. 2 lediglich die an der Tür 5 befestigten Hakenschienen 7 und der Gargutträger
9 abschnittsweise dargestellt. Insbesondere ist die Backofentür 5, die nach
Art eines Backwagens entsprechend dem ersten Ausführungsbeispiel verschiebbar ist,
stark schematisiert dargestellt. Zur Befestigung des Backblechs 9 an der Innenseite
der Backofentür 5 ist an die Hakenschiene 7 ein Gewindestift 21 geschweißt. Dieser ist
durch eine entsprechende Öffnung der Tür 5 gesteckt und von der Tür 5 durch eine
erste Isolationshülse 23 elektrisch isoliert. Die erste Isolationshülse 23 weist weiterhin
einen Hülsenflansch 25 auf, wodurch die Tür 5 ebenfalls von der Hakenschiene 7
elektrisch isoliert ist. Mit Hilfe einer zweiten Isolationshülse 27 ist auch eine zur Befestigung
der Hakenschiene 7 an der Tür 5 dienende Mutter 29 elektrisch von der Tür 5
isoliert. Die beiden Gewindestifte 21 bilden die elektrischen Anschlußstellen für einen
anschließend beschriebenen Verbraucher eines Stromkreises 31. In diesem Stromkreis
liegen zwei Türschalter 33, die bei geöffneter Tür die Stromspeisung der Gewindestifte
21 allpolig abschalten. Weiterhin liegt in Reihe zu den beiden Türschaltem 33
ein Leistungsschalter 35 des Backofens 1. Der Stromkreis 31 wird von einem Netzanschluß
37 des Backofens 1 gespeist. Die Gewindestifte 21 und damit die Hakenschienen
7 liegen also nicht an Netzspannung 37, wenn die Tür 5 geringfügig geöffnet ist.
Auch ist die Spannungsversorgung unterbrochen, wenn sich der Leistungs- bzw. Betriebsschalter
35 noch in seiner Ausstellung befindet. Ist jedoch beispielsweise eine
Betriebsart des Backofens ausgewählt und eine Betriebstemperatur eingestellt sowie
die Backofentür 5 sicher geschlossen, dann sind die beiden Hakenschienen 7 isoliert
voneinander an die Netzspannung 37 gelegt.In the second embodiment shown in Fig. 2 are for reasons of
Simplification essentially the reference numerals of the first shown in Fig. 1
Embodiment adopted unchanged. Furthermore, for reasons of simplification
in Fig. 2 only the hook rails 7 fastened to the
Das emaillierte Backblech 9 weist an seinen beiden Seitenabschnitten befestigte metallische
Trägerteile 39 auf. Diese liegen jeweils mit ihren als wulstartige Lageransätze
41 ausgebildeten Kontaktstellen aufgrund des auftretenden Drehmomentes fest in der
Hakenschiene 7 und sind damit auch sicher elektrisch kontaktiert. Der Träger 39 ist
jeweils mittels zweier voneinander beabstandet angeordneter Niete 43 am Backblechflansch
11 stabil befestigt. Um eine sichere Isolation des Backblechs 9 vom Stromkreis
zu erreichen, ist eine Isolationsscheibe 45 und eine ausreichend dicke, die Oberfläche
des Backblechs 9 allseitig bedeckende Emailleschicht 47 vorgesehen. Am Boden des
Backblechs 9 ist mittels Dickschichttechnik großflächig ein Heizleiter 49 auf der Emailleschicht
47 ausgebildet, der mittels einer Versorgungsleitung 51 an den beiden Trägem
39 des Backblechs 9 und damit an die Netzspannung 37 angeschlossen ist.The enamelled
