Definitions
- the invention relates to an electric baking and roasting oven according to the preamble of claim 1.
- a baking and roasting oven of this type is known from DE-A-32 46 445.
- the plug-in part with integrated heating element, which divides the cooking space volume, is intended to reduce the heating energy expenditure in this known baking and roasting oven. It has been shown, however, that a great deal of heat is radiated or emitted from the insert part and that the cooking space area located below the insert part is also heated to approximately the same temperature value as the cooking area above it by heat conduction via the cooking space walls. Since only the upper cooking area is used in a cooking compartment volume subdivision due to the floor and ceiling heating, or baked or fried food is loaded, the inevitably heated lower cooking area remains unused and the radiated there or by heat conduction supplied heat is lost unused.
- the invention is therefore based on the object to remedy this situation and to ensure that when the cooking space is reduced by moving the cooking space separating plate higher, the warming up of the unused lower cooking space area is largely prevented or made more difficult.
- the oven muffle (1) shown in the drawing for an electric baking and roasting oven delimits a cooking space (2) which can be closed by a door (not shown).
- the oven muffle (1) has a conventional electric heater (3) - Fig. 2 - for the top heat and a lower heater (4) for the bottom heat in the upper cooking area (muffle ceiling).
- the heating element (4) for the bottom heat is advantageously integrated in a separating plate (5) designed as an insertion part, which is provided with electrical plug contacts (6) for the heating element (4). With the help of this slide-in partition plate (5) it is now possible to subdivide the volume of the cooking space (2), so that a smaller cooking space is also available for smaller quantities of baked goods and fried food, which can be heated in a more energy-saving manner.
- the heating element (4) integrated in the cooking space slide-in partition plate (5) is shielded from the cooking chamber floor (7) by high-temperature-resistant thermal insulation (8), so that the heat radiation from the radiator (4) is forcibly directed only upwards in the direction of the muffle ceiling.
- guide rails (10, 10 ⁇ ) are attached for the cooking space insert partition plate (5).
- electrical sockets (12, 12 ⁇ ) are provided for the electrical plug contacts (6) on the partition plate (5) at the appropriate altitude, which are connected via electrical connecting lines to the setting and switching elements of the baking and roasting oven .
- the cooking chamber side walls (9 , 9 ⁇ ) and possibly also in the back wall (11) at the level of the upper partition plate guide (10) interruptions (14) are provided.
- the interruptions (14) are designed as a slotted web arrangement running in the horizontal plane.
- the lateral interruptions (14) are advantageously covered or covered by the guide rails (10) for the partition plate (5), so that they are practically invisible to the user of the cooking space (2) from the front.
- FIG. 2 shows an embodiment in which the heated cooking space partition plate (5 ⁇ ) is not brought into the cooking space subdivision position manually but automatically via a height adjustment device.
- the height adjustment device is operated electrically and put into operation via a corresponding organ.
- the said device consists of a DC motor (21) with left and right rotation. This motor raises or lowers the cooking compartment partition plate (5 ⁇ ) via a cable (22), guide bars (23, 23 ⁇ ) and support bracket (24, 24 ⁇ ) for the cooking compartment partition plate (5 ⁇ ), which is supported by support and slide rollers (25 ) are guided on the guide webs (23, 23 ⁇ ).
- the side guide rails (10 ⁇ ) serve here not only to cover the slot-like interruptions (14) in the muffle side walls (9, 9 ⁇ ) but also as a height limit stop for the cooking space partition plate (5 ⁇ ).
- the separating plate (5 tart) is also provided on the underside with high-temperature-resistant heat insulation (8 ⁇ ) in order to shield the upper heated cooking area from the lower, unheated cooking area.
- an electric heater (not shown) is integrated in the cooking space partition plate (5 ⁇ ) as bottom heat.

Abstract
Description
Die Erfindung betrifft einen elektrischen Back- und Bratofen nach dem Oberbegriff des Patentanspruchs 1.The invention relates to an electric baking and roasting oven according to the preamble of
Aus der DE-A-32 46 445 ist ein Back- und Bratofen dieser Art bekannt. Durch das das Garraum-Volumen unterteilende, steckbar ausgebildete Einschubteil mit integriertem Heizkörper soll bei diesem bekannten Back- und Bratofen der Aufwand an Heizenergie vermindert werden. Es hat sich aber gezeigt, daß vom Einschubteil sehr viel Wärme abgestrahlt bzw. abgegeben wird und außerdem über die Garraumwände durch Wärmeleitung der unterhalb vom Einschubteil befindliche Garraumbereich annähernd auf den gleichen Temperaturwert aufgeheizt wird wie der darüber befindliche Garraumbereich. Da nun bei einer Garraum-Volumen-Unterteilung aufgrund der boden- und deckenseitigen Beheizung an sich dann nur der obere Garraumbereich benutzt bzw. mit Back- oder Bratgut beschickt wird, bleibt der zwangsweise mit aufgeheizte untere Garraumbereich ungenützt und die dorthin abgestrahlte bzw. durch Wärmeleitung zugeführte Wärme geht damit ungenutzt verloren.A baking and roasting oven of this type is known from DE-A-32 46 445. The plug-in part with integrated heating element, which divides the cooking space volume, is intended to reduce the heating energy expenditure in this known baking and roasting oven. It has been shown, however, that a great deal of heat is radiated or emitted from the insert part and that the cooking space area located below the insert part is also heated to approximately the same temperature value as the cooking area above it by heat conduction via the cooking space walls. Since only the upper cooking area is used in a cooking compartment volume subdivision due to the floor and ceiling heating, or baked or fried food is loaded, the inevitably heated lower cooking area remains unused and the radiated there or by heat conduction supplied heat is lost unused.
Bei einem aus der NL-A-8 104 739 bekannten Back- u. Bratofen ist dagegen die in der Garraum-Unterteilungsplatte integrierte Heizeinrichtung gegenüber dem Garraumboden durch eine Wärmeisolierung abgeschirmt. Trotz dieser Maßnahme wird aber der vom Garraum abgetrennte und nicht beheizte untere Garraumbereich durch die Wärmeleitung über die Garraumwände in gewissen Grenzen weiterhin aufgewärmt.In a baking and baking known from NL-A-8 104 739. In contrast, the heating device integrated in the cooking space partition plate is shielded from the cooking space floor by heat insulation. Despite this measure, however, the lower cooking area, which is separated and not heated from the cooking space, continues to be warmed up within certain limits by the heat conduction via the cooking space walls.
Der Erfindung liegt deshalb die Aufgabe zugrunde, hier Abhilfe zu schaffen und sicherzustellen, daß bei einer Verkleinerung des Garraumes durch ein Höherversetzen der Garraum-Trennplatte das Aufwärmen des unbenutzten unteren Garraumbereiches weitgehend unterbunden bzw. erschwert wird.The invention is therefore based on the object to remedy this situation and to ensure that when the cooking space is reduced by moving the cooking space separating plate higher, the warming up of the unused lower cooking space area is largely prevented or made more difficult.
Die Lösung dieser Aufgabe gemäß der Erfindung ist dem kennzeichnenden Teil des Patentanspruchs 1 zu entnehmen.The solution to this problem according to the invention can be found in the characterizing part of
Vorteilhafte weitere Ausgestaltungen des Gegenstandes der Erfindung sind in den Unteransprüchen angegeben.Advantageous further developments of the subject matter of the invention are specified in the subclaims.
Die mit der Erfindung erzielbaren Vorteile sind darin zu sehen, daß bei einer Verkleinerung des Garraumes auch eine erhebliche Einsparung an Heizenergie erreicht wird, da die Wärmezuführung zu dem unbenutzten Teil des Garraumes weitgehend unterbunden ist und dieser Teil des Garraumes damit auch nicht in unnötiger Weise mit aufgeheizt wird.The advantages that can be achieved with the invention can be seen in the fact that when the cooking space is reduced, a considerable saving in heating energy is achieved, since the supply of heat to the unused part of the cooking space is largely prevented and this part of the cooking space is therefore not unnecessarily involved is heated.
Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt und wird anhand dieser nachfolgend näher beschrieben.An embodiment of the invention is shown in the drawing and is described in more detail below with reference to this.
Es zeigen:
- Fig. 1, in perspektivischer Ansicht die Back- und Bratofenmuffel eines elektrischen Back- und Bratofens mit einer als Einschubteil ausgebildeten Garraum-Trennplatte,
- Fig. 2, eine Vorderansicht einer Back- und Bratofenmuffel mit einer Einrichtung zur automatischen Höhenverstellung der Garraum-Trennplatte.
- 1 is a perspective view of the baking and roasting oven muffle of an electric baking and roasting oven with a cooking space partition plate designed as an insert,
- Fig. 2, a front view of a baking and roasting oven muffle with a device for automatic height adjustment of the cooking space partition plate.
Die in der Zeichnung dargestellte Backofenmuffel (1) für einen elektrischen Back- und Bratofen begrenzt einen Garraum (2), der durch eine nicht dargestellte Tür verschließbar ist. Die Backofenmuffel (1) besitzt im oberen Garraumbereich (Muffeldecke) einen üblichen elektrischen Heizkörper (3) - Fig. 2 - für die Oberhitze und einen unteren Heizkörper (4) für die Unterhitze. Der Heizkörper (4) für die Unterhitze ist in vorteilhafter Weise in einer als Einschubteil ausgebildeten Trennplatte (5) integriert, welche mit elektrischen Steckkontakten (6) für den Heizkörper (4) versehen ist. Mit Hilfe dieser Einschub-Trennplatte (5) besteht nun die Möglichkeit, das Volumen des Garraumes (2) zu unterteilen, so daß für kleinere Back- und Bratgutmengen auch ein kleinerer Garraum zur Verfügung steht, der energiesparender aufgeheizt werden kann. Darüber hinaus wird dann auch nur dieser vom eigentlichen Garraum (2) abgeteilte Garraumbereich verschmutzt, während der übrige Garraumbereich sauber bleibt.Der in der Garraum-Einschub-Trennplatte (5) integrierte Heizkörper (4) ist gegenüber dem Garraumboden (7) durch eine hochtemperaturbeständige Wärmeisolierung (8) abgeschirmt, so daß die Wärmeabstrahlung vom Heizkörper (4) zwangsweise nur nach oben in Richtung zur Muffeldecke gerichtet ist. Im Inneren der Backofenmuffel (1) sind an deren Seitenwandungen (9) im unteren und mittleren Bereich Führungsschienen (10, 10ʹ) für die Garraum-Einschub-Trennplatte (5) angebracht. An der Garraumrückwandung (11) sind in der entsprechenden Höhenlage elektrische Steckdosen (12, 12ʹ) für die elektrischen Steckkontakte (6) an der Trennplatte (5) vorgesehen, die über elektrische Verbindungsleitungen mit Einstell- und Schaltorganen des Back- und Bratofens in Verbindung stehen.The oven muffle (1) shown in the drawing for an electric baking and roasting oven delimits a cooking space (2) which can be closed by a door (not shown). The oven muffle (1) has a conventional electric heater (3) - Fig. 2 - for the top heat and a lower heater (4) for the bottom heat in the upper cooking area (muffle ceiling). The heating element (4) for the bottom heat is advantageously integrated in a separating plate (5) designed as an insertion part, which is provided with electrical plug contacts (6) for the heating element (4). With the help of this slide-in partition plate (5) it is now possible to subdivide the volume of the cooking space (2), so that a smaller cooking space is also available for smaller quantities of baked goods and fried food, which can be heated in a more energy-saving manner. In addition, only this cooking space area separated from the actual cooking space (2) is then contaminated, while the rest of the cooking space area remains clean. The heating element (4) integrated in the cooking space slide-in partition plate (5) is shielded from the cooking chamber floor (7) by high-temperature-resistant thermal insulation (8), so that the heat radiation from the radiator (4) is forcibly directed only upwards in the direction of the muffle ceiling. Inside the oven muffle (1) on the side walls (9) in the lower and middle area, guide rails (10, 10ʹ) are attached for the cooking space insert partition plate (5). On the rear wall of the cooking space (11), electrical sockets (12, 12ʹ) are provided for the electrical plug contacts (6) on the partition plate (5) at the appropriate altitude, which are connected via electrical connecting lines to the setting and switching elements of the baking and roasting oven .
Um nun bei Benutzung des oberen Garraumbereiches (Trennplatte (5) ist in den oberen Führungsschienen (10) eingeschoben) eine Wärmeleitung von diesem Garraumbereich in den unterhalb der Trennplatte (5) befindlichen unbenutzten Garraumbereich weitgehend zu unterbinden, sind in den Garraum-Seitenwandungen (9, 9ʹ) und gegebenenfalls auch in der Garraum-Rückwandung (11) in Höhe der oberen Trennplattenführung (10) Unterbrechungen (14) vorgesehen. Die Unterbrechungen (14) sind dabei als eine in horizontaler Ebene verlaufende Schlitzsteg-Anordnung ausgeführt. Die seitlichen Unterbrechungen (14) sind in vorteilhafter Weise durch die Führungsschienen (10) für die Trennplatte (5) ab- bzw. überdeckt, so daß sie für den Benutzer des Garraumes (2) von vorne her praktisch nicht sichtbar sind. Zweckmäßig ist es, die Führungsschienen (10) nur punktförmig an der Garraumseitenwandung (9) anzubringen, um auch von dieser Seite her die Wärmeleitung bzw. Wärmeübertragung zu verringern. Um die Außenwandung der Backofenmuffel (1) wird in üblicher Weise eine Wärmeisolierung gelegt, durch die die Unterbrechungen (14) in den Muffelwandungen nach außen hin überdeckt sind. Vorteilhaft ist es auch, den vorderen Rahmen (15) der Backofenmuffel (1) ebenfalls mit schlitzartigen Unterbrechungen (16) zu versehen, um dadurch die Wärmeleitung vom oberen Garraumbereich zum unteren Garraumbereich noch weiter zu unterbinden.In order to largely prevent heat conduction from this cooking space area into the unused cooking space area below the partition plate (5) when using the upper cooking space area (partition plate (5) is inserted in the upper guide rails (10)), the cooking chamber side walls (9 , 9ʹ) and possibly also in the back wall (11) at the level of the upper partition plate guide (10) interruptions (14) are provided. The interruptions (14) are designed as a slotted web arrangement running in the horizontal plane. The lateral interruptions (14) are advantageously covered or covered by the guide rails (10) for the partition plate (5), so that they are practically invisible to the user of the cooking space (2) from the front. It is expedient to attach the guide rails (10) to the cooking chamber side wall (9) only in a punctiform manner in order to also reduce the heat conduction or heat transfer from this side. In the usual way, thermal insulation is placed around the outer wall of the oven muffle (1) by which the interruptions (14) in the muffle walls are covered to the outside. It is also advantageous to also provide the front frame (15) of the oven muffle (1) with slot-like interruptions (16) in order to further prevent heat conduction from the upper cooking area to the lower cooking area.
Gemäß Weiterbildung der Erfindung zeigt Fig. 2 ein Ausführungsbeispiel, bei dem die beheizte Garraum-Trennplatte (5ʹ) nicht manuell sondern automatisch über eine Höhenverstellungseinrichtung in die Garraum-Unterteilungsposition gebracht wird. Die Höhenverstellungseinrichtung wird dabei elektrisch betrieben und über ein entsprechendes Organ in Betrieb gesetzt. Die genannte Einrichtung besteht aus einem Gleichstrommotor (21) mit Links- und Rechtslauf. Dieser Motor hebt bzw. senkt die Garraum-Trennplatte (5ʹ) über einen Seilzug (22), Führungsstegen (23, 23ʹ) und Tragewinkel (24, 24ʹ) für die Garraum-Trennplatte (5ʹ), die mittels Stütz- und Gleitrollen (25) an den Führungsstegen (23, 23ʹ) geführt sind. Die seitlichen Führungsschienen (10ʺ) dienen hier neben der Abdeckung der schlitzartigen Unterbrechungen (14) in den Muffel-Seitenwänden (9, 9ʹ) auch als Höhenbegrenzungsanschlag für die Garraum-Trennplatte (5ʹ). Die Trennplatte (5ʹ) ist auch bei diesem Ausführungsbeispiel unterseitig mit einer hochtemperaturbeständigen Wärmeisolierung (8ʹ) versehen, um den oberen beheizten Garraumbereich gegenüber dem unteren, unbeheizten Garraumbereich entsprechend abzuschirmen. Weiterhin ist in der Garraum-Trennplatte (5ʹ) als Unterhitze ein nicht dargestellter elektrischer Heizkörper integriert.According to a further development of the invention, FIG. 2 shows an embodiment in which the heated cooking space partition plate (5ʹ) is not brought into the cooking space subdivision position manually but automatically via a height adjustment device. The height adjustment device is operated electrically and put into operation via a corresponding organ. The said device consists of a DC motor (21) with left and right rotation. This motor raises or lowers the cooking compartment partition plate (5ʹ) via a cable (22), guide bars (23, 23ʹ) and support bracket (24, 24ʹ) for the cooking compartment partition plate (5ʹ), which is supported by support and slide rollers (25 ) are guided on the guide webs (23, 23ʹ). The side guide rails (10ʺ) serve here not only to cover the slot-like interruptions (14) in the muffle side walls (9, 9ʹ) but also as a height limit stop for the cooking space partition plate (5ʹ). In this exemplary embodiment, the separating plate (5 hoch) is also provided on the underside with high-temperature-resistant heat insulation (8ʹ) in order to shield the upper heated cooking area from the lower, unheated cooking area. Furthermore, an electric heater (not shown) is integrated in the cooking space partition plate (5ʹ) as bottom heat.
