Description

Die Erfindung betrifft einen elektrisch beheizten Bratofen mit Unter- und Oberbeheizung und mit integrierter Mikrowelleneinrichtung.The invention relates to an electrically heated roasting oven with bottom and top heating and with an integrated microwave device.

Ein Bratofen dieser Art ist aus der DE-OS 26 05 699 bekannt. Die Zubereitung bzw. Garung des Gutes kann bei diesem Bratofen auf herkömmliche Weise unter Einschaltung der Unter- und/oder Oberbeheizung des Bratofens erfolgen. Bei Benutzung der Mikrowelleneinrichtung zum Garen wird zu deren Unterstützung noch zusätzlich die Unter- und/oder Oberbeheizung zugeschaltet, um dem Äußeren des Gargutes eine gewisse Bräunung und somit Geschmacksverbesserung zu geben.A roasting oven of this type is known from DE-OS 26 05 699. The preparation or cooking of the food can take place in this roasting oven in a conventional manner by switching on the bottom and / or top heating of the roasting oven. When using the microwave device for cooking, the bottom and / or top heating is additionally switched on to support it, in order to give the exterior of the item to be cooked a certain degree of browning and thus an improvement in taste.

Es hat sich nun aber in der Praxis gezeigt, daß bei gleichzeitigem Einsatz der Unter- und Oberbeheizung im Bratofen und der Mikrowelleneinrichtung infolge der verhältnismäßig langen An- bzw. Aufheizzeit des Bratofens trotzdem keine befriedigenden Bratergebnisse erzielbar sind.However, it has now been shown in practice that if the bottom and top heating in the roasting oven and the microwave device are used at the same time, satisfactory roasting results can still not be achieved due to the relatively long heating or heating time of the roasting oven.

Hier will die Erfindung Abhilfe schaffen. Die Erfindung, wie sie in den Ansprüchen gekennzeichnet ist, löst die Aufgabe, einen elektrisch beheizten Bratofen der eingangs genannten Art so weiterzubilden, daß die Qualität des Gargutes verbessert und die Garzeit verkürzt wird.The invention seeks to remedy this. The invention, as characterized in the claims, solves the problem of developing an electrically heated roasting oven of the type mentioned in such a way that the quality of the food to be cooked is improved and the cooking time is shortened.

Die mit der Erfindung erreichten Vorteile sind im wesentlichen darin zu sehen, daß bei jedem Einschaltvorgang zunächst eine große Aufheizleistung für den Bratofen zur Verfügung steht, durch die der Bratofen bzw. der Bratraum in einer relativ kurzen Zeitspanne auf etwa 2500C aufgeheizt und nach Erreichen der genannten Temperatur automatisch auf eine kleinere Heizleistung bestehend aus der Unter-und Oberbeheizung zurückgeschaltet wird. Daraus ergibt sich nicht nur der Vorteil einer verkürzten Garzeit insgesamt, sondern das Gargut und zwar insbesondere das Bratgut wird auch bei Einsatz der zeitsparenden Mikrowelleneinrichtung gut durchgebraten, so daß sich die den Geschmack eines Bratens bewirkenden Geschmacks- bzw. Aromastoffe auch voll entwickeln bzw. bilden können.The advantages achieved with the invention are to be seen essentially in the fact that at each power initially a large heating capacity is the roasting oven is available, through which the roasting oven or Bratraum heated in a relatively short period at about 250 0 C and after reaching the temperature mentioned is automatically switched back to a lower heating output consisting of the lower and upper heating. This not only gives the advantage of a shortened overall cooking time, but the food to be cooked, and in particular the food to be fried, is also well-fried when the time-saving microwave device is used, so that the flavoring or flavoring substances which cause the taste of a roast also develop fully can.

Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt und wird an Hand dieser nachfolgend näher beschrieben. Es zeigt

  • Figur 1 einen mit einer Mikrowelleneinrichtung bzw. -beheizung versehenen Bratofen eines Herdes,
  • Figur 2 ein Schaltbild für die Steuerung der Beheizung dieses Bratofens und
  • Figur 3 ein Diagramm, welches den Temperaturanstieg im Bratraum pro Zeit mit und ohne Zusatzheizung darstellt.
An embodiment of the invention is shown in the drawing and will be described in more detail below with reference to this. It shows
  • FIG. 1 shows a roasting oven of a cooker provided with a microwave device or heating,
  • Figure 2 is a circuit diagram for controlling the heating of this roasting oven and
  • Figure 3 is a diagram showing the temperature rise in the roasting chamber per time with and without additional heating.

Das Bratofengehäuse 1 für einen nicht weiter dargestellten Herd besitzt an seiner Unterseite 1' eine bekannte Mikrowelleneinrichtung bzw. -beheizung 2 und einen darüber angeordneten, als Unterheizung dienenden Heizstab 3. Der inneren Oberseite 1" des Bratofengehäuses 1 ist ein als Oberbeheizung dienender Heizstab 4 und zwischen diesem ein weiterer Heizstab 5, der als Zusatzheizung verwendet wird, vorgesehen. Zwischen den oberen Heizstäben 4 und 5 und der inneren Oberseite 1" des Bratofengehäuses 1 ist ein Strahlblech 6 angeordnet, welches die Strahlungswärme der Heizstäbe 4 und 5 nach unten zu auf das Bratgut lenkt.The roasting oven housing 1 for a cooker (not shown further) has a known microwave device or heating 2 on its underside 1 'and a heating rod 3 arranged above it, which serves as an underheater. The inner top side 1 "of the roasting oven housing 1 is a heating rod 4 and a further heating rod 5, which is used as additional heating, is provided between the latter. Between the upper heating rods 4 and 5 and the inner upper side 1 ″ of the roasting oven housing 1, a radiant panel 6 is arranged, which directs the radiant heat of the heating rods 4 and 5 down to the food to be fried.

Wie das Schaltbild nach Figur 2 zeigt, sind der Oberhitze-Heizstab 4 und der Unterhitze-Heizstab 3 parallel geschaltet und werden von einem in Reihe dazu liegenden verstellbaren Temperaturregler 7 gesteuert. Der verstellbare Temperaturregler 7 spricht auf die jeweils eingestellte bzw. vorgewählte Temperatur für den Bratraum des Bratofens 1 an und hält den Bratraum auf diese Temperatur. Der Regelbereich dieses Temperaturreglers 7 liegt dabei im Bereich von etwa 500 bis 300°C. Über einen von einem Schaltknebel betätigbaren Kontakt 8 können der Oberhitze-Heizstab 4 und der Unterhitze-Heizstab 3 eingeschaltet werden.As the circuit diagram according to FIG. 2 shows, the upper heat heating rod 4 and the lower heat heating rod 3 are connected in parallel and are controlled by an adjustable temperature controller 7 located in series with them. The adjustable temperature controller 7 responds to the respectively set or preselected temperature for the roasting space of the roasting oven 1 and keeps the roasting space at this temperature. The control range of this temperature controller 7 is in the range of about 50 0 to 300 ° C. The top heat rod 4 and the bottom heat rod 3 can be switched on via a contact 8 which can be actuated by a switch toggle.

Parallel zu dem Oberhitze-Heizstab 4 und Unterhitze-Heizstab 3 ist der Zusatz-Heizstab 5 gelegt, der von einem auf eine Temperatur im Bratraum von etwa 250°C fest eingestellten Temperaturschalter 9 geschaltet wird. Eingeschaltet wird der Zusatz-Heizstab 5 über ein Schaltglied 10, welches ein übliches Relais oder ein elektronisches oder mechanisches Zeitglied sein kann.Parallel to the upper heat heating rod 4 and lower heat heating rod 3 is the additional heating rod 5, which is switched by a temperature switch 9 which is set to a temperature in the roasting chamber of approximately 250 ° C. The additional heating element 5 is switched on via a switching element 10, which can be a conventional relay or an electronic or mechanical timer.

Wie die Kennlinie 1 im Diagramm in Figur 3 zeigt, steigt die Temperatur im Bratraum, wenn nur der Oberhitze-Heizstab 4 und der Unterhitze-Heizstab 3 eingeschaltet sind, nur sehr langsam auf 250°C an. Bei Zuschaltung des Zusatzheizkörpers 5 stellt sich jedoch, wie die Kennlinie II zeigt, im Bratraum in einem wesentlich kürzeren Zeitraum die gewünschte Temperatur von 250°C ein, was bei einem solchen Bratofen insbesondere bei Verwendung der zeitsparenden Mikrowelleneinrichtung bzw. -beheizung beim Garen von Braten oder dgl. von Vorteil ist.As the characteristic curve 1 in the diagram in FIG. 3 shows, the temperature in the roasting chamber rises very slowly to 250 ° C. when only the upper heat heating element 4 and the lower heat heating element 3 are switched on. When the additional heater 5 is switched on, however, as the characteristic curve II shows, the desired temperature of 250 ° C. is set in the roasting chamber in a considerably shorter period of time, which is particularly the case with such a roasting oven when using the time-saving microwave device or heating when roasting or the like. is advantageous.
