Description

Gargerät mit einer Schnellaufheizeinheit Cooking appliance with a rapid heating unit
Die Erfindung geht aus von einem Gargerät mit einer Schnellaufheizeinheit nach dem Oberbegriff des Anspruchs 1.The invention relates to a cooking appliance with a rapid heating unit according to the preamble of claim 1.
Aus der US 5 432 321 ist ein gattungsbildendes Gargerät mit einer Oberhitze-Heizeinheit, einer Unterhitze-Heizeinheit, einer Heißluft-Heizeinheit sowie mit einer Schnellaufheizeinheit zur Einstellung eines Schnellaufheizmodus bekannt. Bei einer Grundbetriebsart mit aktivierter Oberhitze-Heizeinheit und aktivierter Unterhitze-Heizeinheit kann über einen Betätigungsschalter der Schnellaufheizeinheit und über ein Steuergerät die Heißluft- Heizeinheit zur Einstellung des Schnellaufheizmodus aktiviert werden.From US 5 432 321 a generic cooking device with an upper heat heating unit, a lower heat heating unit, a hot air heating unit and with a rapid heating unit for setting a rapid heating mode is known. In a basic operating mode with activated top heat heating unit and activated bottom heat heating unit, the hot air heating unit can be activated via an actuation switch of the quick heating unit and a control unit to set the quick heating mode.
Die Aufgabe der Erfindung besteht darin, eine gattungsgemäße Vorrichtung bereitzustellen, bei der eine vorteilhaft schnelle Aufheizung erreichbar und bei der zudem ein uner- wünschtes Einbrennen von Speiseresten während des Schnellaufheizmodus zumindest weitgehend vermieden werden kann. Die Aufgabe wird erfindungsgemäß durch die Merkmale des Patentanspruchs 1 gelöst, während vorteilhafte Ausgestaltungen und Weiterbildungen der Erfindung den Unteransprüchen entnommen werden können.The object of the invention is to provide a generic device in which an advantageously rapid heating can be achieved and in which an undesired baking-in of food residues during the rapid heating mode can at least largely be avoided. The object is achieved by the features of patent claim 1, while advantageous refinements and developments of the invention can be found in the subclaims.
Die Erfindung geht aus von einem Gargerät mit einer einen Garraum begrenzenden Muffel, zumindest einer oberen Heizeinheit, einer Heißluft-Heizeinheit und einer Schnellaufheizeinheit zur Einstellung eines Schnellaufheizmodus sowie mit einer Steuereinheit.The invention is based on a cooking device with a muffle delimiting a cooking space, at least an upper heating unit, a hot air heating unit and a rapid heating unit for setting a rapid heating mode, and with a control unit.
Es wird vorgeschlagen, daß die Steuereinheit ausschließlich im Betrieb mit der Heißluft- Heizeinheit den Schnellaufheizmodus einstellt und dabei die obere Heizeinheit zuschaltet. Es kann vermieden werden, daß die Unterhitze-Heizeinheit während des Schnellaufheizmodus aktiviert ist und daß Speisereste, die sich in der Regel im unteren Bereich der Muffel befinden, durch eine aktivierte Unterhitze-Heizeinheit und die aktivierte Heißluft- Heizeinheit während des Schnellaufheizmodus einbrennen. Ferner sind die oberen Heiz- einheiten häufig innerhalb einer Muffel des Gargeräts angeordnet, so daß über die Heißluft-Heizeinheit die Wärme an der oberen Heizeinheit vorteilhaft abgeführt und im Garraum verteilt werden kann, wodurch ein hoher Wirkungsgrad und eine schnelle Aufhei- zung erreicht werden kann. Zudem kann eine einfache, kostengünstige Steuerung erreicht werden, insbesondere kann ein einfaches und kostengünstiges Relais ohne Wechsler für die Schnellaufheizeinheit verwendet werden. Die erfindungsgemäße Lösung kann sowohl bei Gargeräten mit elektromechanischer als auch bei Gargeräten mit elektronischer Backofensteuerung eingesetzt werden.It is proposed that the control unit set the rapid heating mode only in operation with the hot air heating unit and thereby switch on the upper heating unit. It can be avoided that the bottom heating unit is activated during the rapid heating mode and that food residues, which are usually located in the lower area of the muffle, are burned in by an activated bottom heating unit and the activated hot air heating unit during the rapid heating mode. Furthermore, the upper heating units are often arranged within a muffle of the cooking device, so that the heat can advantageously be removed from the upper heating unit via the hot-air heating unit and distributed in the cooking space, as a result of which a high degree of efficiency and rapid heating tion can be achieved. In addition, a simple, inexpensive control can be achieved, in particular a simple and inexpensive relay without a changer can be used for the rapid heating unit. The solution according to the invention can be used both in cooking devices with electromechanical and in cooking devices with electronic oven control.
Die obere Heizeinheit kann grundsätzlich von einer Oberhitze-Heizeinheit und/oder von einer Grill-Heizeinheit gebildet sein, wobei mit einer Oberhitze-Heizeinheit mit einem relativ geringen Energiebedarf und einer kostengünstigen elektrischen Absicherung ein hoher Wirkungsgrad und mit einer Grill-Heizeinheit eine besonders schnelle Aufheizung reali- siert werden kann.The upper heating unit can in principle be formed by an upper heating unit and / or by a grill heating unit, with an upper heating unit with a relatively low energy requirement and inexpensive electrical protection, a high degree of efficiency and with a grill heating unit a particularly rapid heating can be realized.
Stellt die Steuereinheit ausschließlich in einer Aufheizphase den Schnellaufheizmodus ein, kann unnötiger Energieverlust vermieden und Fehlbedienungen können verhindert werden.If the control unit sets the rapid heating mode only in a heating phase, unnecessary energy loss can be avoided and incorrect operation can be prevented.
Die Schnellaufheizeinheit kann automatisch und/oder manuell über einen Schalter steuerbar ausgeführt werden. Mit einer automatischen Steuerung kann ein besonders hoher Komfort und mit einer manuellen Steuerung kann eine besonders individuell anpaßbare Betätigung erreicht werden.The rapid heating unit can be controlled automatically and / or manually via a switch. With automatic control, a particularly high level of comfort can be achieved, and with manual control, a particularly individually adjustable actuation can be achieved.
Ferner wird vorgeschlagen, daß ein Backofenregler der Steuereinheit die obere, im Schnellaufheizmodus zugeschaltete Heizeinheit abschaltet, wenn eine Solltemperatur erreicht ist, wodurch zusätzliche Steuer- und/oder Regelbausteine vermieden werden können.It is further proposed that an oven controller of the control unit switches off the upper heating unit, which is switched on in the rapid heating mode, when a target temperature is reached, as a result of which additional control and / or regulating modules can be avoided.
Aktiviert die Steuereinheit mit der im Schnellaufheizmodus zugeschalteten, oberen Heizeinheit zumindest ein Signalelement, kann über das vom Signalelement abgegebene Signal eine weitere Einheit gesteuert und insbesondere kann einem Bediener angezeigt werden, daß sich das Gargerät im Schnellaufheizmodus befindet.If the control unit activates at least one signal element with the upper heating unit switched on in the rapid heating mode, a further unit can be controlled via the signal emitted by the signal element and in particular an operator can be shown that the cooking device is in the rapid heating mode.

An operating unit 21 of the baking oven 1 is arranged above the muffle 11. The operating unit 21 has five actuating elements mounted in a housing arranged under a panel, namely two actuating buttons 23, 24 arranged below a time display 22 for actuating a time switch, and a retractable toggle 26 arranged centrally below an operating mode display 25 an operating mode and a retractable toggle 28 arranged below a temperature display 27 for selecting an operating temperature and an actuation button 17 arranged next to the retractable knee at 28 for activating a rapid heating unit 15 or for setting a rapid heating mode (FIGS. 1 and 2).
Der Backofen 1 besitzt eine Steuereinheit 16, und zwar mit acht dem Knebel 26 zugeordneten Schaltkontakten P1 bis P8, einem Relais K1 für ein Kühlgebläse mit einem Kühlge- bläsemotor 36, einem Relais K2 für Backofenlampen 34, 35 und für einen Heißluft- bzw. Umluftmotor 33, einem Backofentaktrelais K3 und einem Relais K4 der Schnellaufheizeinheit 15. Das Relais K4 ist über die Betätigungstaste 17 schaltbar und besitzt einen Haltekontakt 37 sowie einen Leistungskontakt 38. Ferner besitzt die Steuereinheit 16 einen Backofenregler 29, der mit einem Temperaturbegrenzer 30 zusammenwirkt.The oven 1 has a control unit 16, specifically with eight switch contacts P1 to P8 assigned to the knob 26, a relay K1 for a cooling fan with a cooling fan motor 36, a relay K2 for oven lamps 34, 35 and for a hot-air or circulating-air motor 33, an oven clock relay K3 and a relay K4 of the rapid heating unit 15. The relay K4 can be switched via the actuation button 17 and has a hold contact 37 and a power contact 38. Furthermore, the control unit 16 has an oven controller 29 which interacts with a temperature limiter 30.
Der Backofen 1 besitzt ferner eine innerhalb der Muffel 11 angeordnete Oberhitze- Heizeinheit 12 mit einer Heizleistung von 1100 W, eine Unterhitze-Heizeinheit 31 mit einer Heizleistung von 1100 W, eine Grill-Heizeinheit 13 mit einer Heizleistung von 1600 W, eine Heißluft-Heizeinheit 14 mit einem Ringheizkörper 32 mit einer Heizleistung von 2400 W und einem Umluftmotor 33, die über die Steuereinheit 16 schaltbar sind (Fig. 2). Die Grundbetriebsart des Backofens 1 ist der Betrieb mit der Heißluft-Heizeinheit 14.The oven 1 also has an upper heat heating unit 12 arranged within the muffle 11 with a heating output of 1100 W, a lower heating unit 31 with a heating output of 1100 W, a grill heating unit 13 with a heating output of 1600 W, a hot air heating unit 14 with a ring heater 32 with a heating power of 2400 W and a circulating air motor 33, which can be switched via the control unit 16 (Fig. 2). The basic operating mode of the oven 1 is the operation with the hot air heating unit 14.
Erfindungsgemäß kann über die Betätigungstaste 17 ausschließlich im Betrieb mit der Heißluft-Heizeinheit 14, d.h. in der Grundbetriebsart oder in einer Betriebsart zum Backen von Brot, bei der die Heißluft-Heizeinheit 14 mit einer hohen Leistung betrieben wird, sowie ausschließlich während einer Aufheizphase die Schnellaufheizeinheit 15 aktiviert und ein Schnellaufheizmodus eingestellt werden. Dabei wird über das Relais K4 der Schnellaufheizeinheit 15 die Oberhitze-Heizeinheit 12 zugeschaltet, so daß sich im Schnellauf- heizmodus eine kumulierte Heizleistung von 3500 W ergibt. Ferner wird eine unterhalb der Betäti-gungstaste 17 angeordnete Signalleuchte 18 aktiviert, die die Betätigungstaste beleuchtet und einem Bediener den eingestellten Schnellaufheizmodus anzeigt. Grundsätzlich könnte die Steuereinheit 16 auch in der Weise ausgelegt werden, daß die Grill- Heizeinheit 13 allein oder wahlweise mit der Oberhitze-Heizeinheit 12 im Schnellaufheiz- modus aktiviert ist.According to the invention, the actuation button 17 can only be used in operation with the hot air heating unit 14, i.e. in the basic mode or in an operating mode for baking bread, in which the hot air heating unit 14 is operated at a high output, and only during a heating-up phase, the rapid heating unit 15 is activated and a rapid heating mode is set. The top heating unit 12 is switched on via the relay K4 of the rapid heating unit 15, so that there is a cumulative heating power of 3500 W in the rapid heating mode. Furthermore, a signal light 18 arranged below the actuation key 17 is activated, which illuminates the actuation key and indicates to an operator the set rapid heating mode. In principle, the control unit 16 could also be designed in such a way that the grill heating unit 13 is activated alone or optionally with the top heat heating unit 12 in the rapid heating mode.
Ist eine Solltemperatur erreicht, wird die Schnellaufheizeinheit 15 bzw. die im Schnellaufheizmodus zugeschaltete Oberhitze-Heizeinheit 12 über den Backofenregler 29 der Steuereinheit 16 abgeschaltet. Wird die eingestellte Backofentemperatur am Knebel 28 erhöht, kann wiederum die Schnellaufheizeinheit 15 über die Betätigungstaste 17 aktiviert werden. If a target temperature has been reached, the rapid heating unit 15 or the top heat heating unit 12 switched on in the rapid heating mode is switched off via the oven controller 29 of the control unit 16. If the oven temperature set on the knob 28 is increased, the rapid heating unit 15 can in turn be activated via the actuation button 17.
