Description

Die Erfindung betrifft ein Gargerät mit einem Gehäuse, einem in dem Gehäuse angeordneten, über eine Tür verschließbaren Garraum, sowie mit mindestens einem, eine optische Leuchtanzeige aufweisenden Bedien- und Anzeigefeld. Ein Gargerät gemäß dem Oberbegriff von Anspruch 1 ist beispielsweise aus der EP-A-0 156 717 bekannt.The invention relates to a cooking appliance with a housing, arranged in the housing, closable via a door cooking chamber, as well as with at least one, a visual light display having control and display panel. A cooking appliance according to the preamble of claim 1 is known for example from EP-A-0 156 717.

Zum Bedienen von elektrischen Haushaltsgeräten ist es bekannt, diese mit einer Leuchtanzeige auszustatten, damit auch aus weiter Entfernung erkennbar ist, ob das Haushaltsgerät ein- oder ausgeschaltet ist. Aus der DE-OS 1 964 483 ist beispielsweise ein Herd bekannt, bei dem die Leuchtanzeige als von einer Lichtquelle durchleuchtetes Lichtband ausgebildet ist. Da aber bei Herden der Garraum auch ohne gleichzeitige Beheizung des Garraums beleuchtet werden kann und somit die zugehörige Leuchtanzeige nur den eingeschalteten Betriebszustand des Herdes signalisiert, ist die Leuchtanzeige für den Benutzer kein Hinweis dafür, ob der Garraum und damit auch die Frontseite der den Garraum verschließenden Tür heiß oder kalt ist, so dass trotz der Leuchtanzeige die Gefahr besteht, dass der Benutzer des Herdes sich an der Tür Verbrennungen zuzieht.To operate household electrical appliances, it is known to equip them with a light indicator, so that it can be seen from far away whether the household appliance is on or off. From DE-OS 1 964 483, for example, a stove is known in which the light indicator is designed as a light source illuminated by a light band. But since herd the oven can be lit without simultaneous heating of the oven and thus the associated indicator only signals the on mode of operation of the stove, the light indicator for the user is no indication of whether the cooking chamber and thus the front of the cooking chamber occlusive Door is hot or cold, so that despite the light indicator there is a risk that the user of the cooker burns on the door.

Davon ausgehend liegt der Erfindung die Aufgabe zugrunde, die Leuchtanzeige eines Gargeräts der eingangs genannten Art so auszugestalten, dass die Anzeige des Gargeräts verbessert ist.Based on this, the invention has the object, the light display of a cooking appliance of the type mentioned in such a way that the display of the cooking appliance is improved.

Die Aufgabenstellung wird erfindungsgemäß dadurch gelöst, dass über die optische Leuchtanzeige des Bedien- und Anzeigefelds zusätzlich zur Ein- und/oder Ausschaltstellung verschiedene Betriebszustände des Garraums darstellbar sind.The task is inventively achieved in that on the optical indicator of the control and display panel in addition to the input and / or switch-off different operating states of the cooking chamber can be displayed.

Durch die erfindungsgemäße Ausgestaltung der Leuchtanzeige des Bedien- und Anzeigefelds ist es möglich, dem Benutzer des Gargeräts nicht nur zu verdeutlichen, dass das Gerät ein- oder ausgeschaltet ist, sondern ihm zusätzlich den Betriebszustand auf den ersten Blick und auch über eine größere Entfernung anzuzeigen, das heißt, beispielsweise darzustellen, ob sich der Garraum in der Aufheizphase, der Abkühlungsphase oder im Selbstreinigungsprozess befindet; der Benutzer kann somit durch die Leuchtanzeige über die Temperatur des Garraums informiert werden.Due to the inventive design of the illuminated display of the control and display panel, it is possible not only to make clear to the user of the cooking appliance that the device is switched on or off, but also indicate the operating state at first glance and also over a greater distance, that is, for example, to represent whether the cooking chamber is in the heating phase, the cooling phase or in the self-cleaning process; the user can thus be informed by the indicator on the temperature of the cooking chamber.

Gemäß einer ersten praktischen Ausführungsform der Erfindung ist die Leuchtanzeige als im wesentlichen lineares Leuchtband ausgebildet, dessen Länge vorteilhafterweise der Breite des Sichtfensters in der den Garraum verschließenden Tür entspricht, wodurch eine einfache und eindeutige optische Beziehung zwischen der Leuchtanzeige und dem Garraum, dessen Betriebszustand darzustellen ist, erzielt wird.According to a first practical embodiment of the invention, the light display is formed as a substantially linear light strip whose length advantageously corresponds to the width of the viewing window in the cooking chamber occlusive door, whereby a simple and unique optical relationship between the light display and the cooking chamber, to represent its operating state , is achieved.

Bei einer zweiten praktischen Ausführungsform der Erfindung ist die Leuchtanzeige als Schwellpfeil ausgebildet, so dass aus der Größe des leuchtenden Pfeils einfach auf die aktuelle Temperatur im Garraum zu schließen ist.In a second practical embodiment of the invention, the light indicator is designed as a threshold arrow, so that from the size of the luminous arrow is easy to close on the current temperature in the oven.

Um über die Leuchtanzeige aus der Entfernung feststellen zu können, ob im Garraum eine hohe oder eine niedrige Temperatur herrscht, wird gemäß einer ersten Ausführungsform vorgeschlagen, dass die Lichtintensität der Leuchtanzeige im Verhältnis zur Temperatur des Garraums steht, dass heißt, dass die Lichtintensität der Leuchtanzeige beispielsweise mit zunehmender Temperatur ebenfalls zunimmt.In order to be able to determine from the distance via the illuminated display whether a high or a low temperature prevails in the cooking chamber, it is proposed according to a first embodiment that the light intensity of the illuminated display is in relation to the temperature of the cooking chamber, that is to say that the light intensity of the illuminated display For example, with increasing temperature also increases.

Eine weitere oder auch zusätzlich verwendbare Möglichkeit, die Temperatur des Garraums über die Leuchtanzeige darzustellen, besteht darin, dass die beleuchtete Länge der im wesentlichen linearen Leuchtanzeige im Verhältnis zur Temperatur des Garraums steht, was bedeutet, dass ein um so längerer Abschnitt der Leuchtanzeige aktiviert ist, desto höher die Temperatur des Garraums ist.A further or additionally usable possibility to display the temperature of the cooking chamber via the illuminated display is that the illuminated length of the substantially linear illuminated display is in relation to the temperature of the cooking chamber, which means that the longer the section of the illuminated display is activated , the higher the temperature of the cooking chamber.

Da bei der Selbstreinigung des Garraums, beispielsweise mittels Pyrolyse oder anderer bekannter Selbstreinigungsverfahren, sehr hohe Temperaturen im Garraum und somit auch an der Garraumtür erreicht werden, wird erfindungsgemäß vorgeschlagen, dass die Leuchtanzeige während der Selbstreinigung blinkt, um auf diese Weise als Warnfunktion zu wirken.Since in the self-cleaning of the cooking chamber, for example by means of pyrolysis or other known self-cleaning method, very high temperatures in the oven and thus also on the cooking chamber door, it is proposed according to the invention that the indicator flashes during self-cleaning, to act in this way as a warning function.

Zusätzlich zu der Temperaturinformation über die Leuchtanzeige wird mit der Erfindung vorgeschlagen, dass die jeweilige exakte Temperatur mittels einer Digitalanzeige anzeigbar ist.In addition to the temperature information on the illuminated display is proposed with the invention that the respective exact temperature can be displayed by means of a digital display.

Weiterhin ist es mit der erfindungsgemäßen Leuchtanzeige möglich, den Betriebszustand Aufheizphase anzuzeigen. Hierzu ist die Leuchtanzeige so ausgelegt, dass die gerade erreichte Temperatur des Garraums als Dauerlicht angezeigt wird, während der Bereich bis zur vorgewählten Endtemperatur als Blinklicht dargestellt wird.Furthermore, it is possible with the light indicator according to the invention to indicate the operating state heating phase. For this purpose, the light indicator is designed so that the just reached temperature of the cooking chamber is displayed as a continuous light, while the range is displayed up to the preselected end temperature as a flashing light.

Schließlich wird mit der Erfindung vorgeschlagen, dass die Leuchtanzeige zusätzlich mit einer Temperaturskala versehen ist, um ein exaktes Erfassen der durch die Leuchtanzeige visualisierten Temperatur zu ermöglichen.Finally, it is proposed with the invention that the illuminated display is additionally provided with a temperature scale in order to enable an exact detection of the temperature visualized by the illuminated display.

Weiterhin weist das Gargerät einen im Gehäuse 1 angeordneten, über eine mit einem Sichtfenster 4a versehenen Tür 4 verschließbaren Garraum 5 auf. Zum Zum Aktivieren der einzelnen Heizeinrichtungen 3 der Kochfeldplatte 2 sowie des Garraums 5 dient ein Bedien- und Anzeigefeld 6 mit einzelnen, den Heizeinrichtungen 3 und dem Garraum 5 zugeordneten, Bedienelementen 7.Figure 1 shows a perspective view of a cooking appliance, the housing 1 is completed at the top of a hob plate 2, in which four heaters 3 are integrated. Furthermore, the cooking appliance has a cooking chamber 5 arranged in the housing 1 and closable via a door 4 provided with a viewing window 4a. Zum Zum Activation of the individual heaters 3 of the hob plate 2 and the cooking chamber 5 is an operating and display panel 6 with individual, the heaters 3 and the cooking chamber 5 associated controls 7.

Neben den Bedienelementen 7 zum Ein- und Ausschalten sowie zur Temperaturregulierung der Heizeinrichtungen 3 und des Garraums 5 ist das Bedien- und Anzeigefeld 6 mit einer optischen Leuchtanzeige 8 ausgestattet. Diese gemäß einer ersten Ausführungsform als lineares Leuchtband ausgebildete Leuchtanzeige 8 dient dazu, den jeweiligen Betriebszustand des Garraums 5 anzuzeigen. Wie nachfolgend noch zur Abbildung Fig. 2 ausgeführt wird, ermöglicht die Leuchtanzeige 8 nicht nur anzuzeigen, ob der Garraum 5 ein- oder ausgeschaltet ist, vielmehr ist es möglich, mittels der Leuchtanzeige 8 den aktuellen Betriebszustand, wie beispielsweise eine Aufheizphase oder eine Selbstreinigungsphase darzustellen. Auch im Garraum vorhandene Restwärme kann angezeigt werden oder die Beendigung eines Garvorganges durch entsprechenden Wechsel des Leuchtbildes. Zusätzlich alternativ kann vorgesehen sein, dass ein Kochfeld (wird gezeigt) des Gargerätes vorgesehen ist, und dass die Leuchtanzeige 8 Betriebszustände des Kochfeldes anzeigt, wie z. B. dass eine bestimmte Temperatur oder ein definierter Garzustand erreicht ist.In addition to the controls 7 for switching on and off and for temperature control of the heaters 3 and the cooking chamber 5, the control and display panel 6 is equipped with a visual light indicator 8. This designed according to a first embodiment as a linear light strip illuminated display 8 serves to indicate the respective operating state of the cooking chamber 5. As will be explained below with reference to FIG. 2, the illuminated display 8 not only allows to indicate whether the cooking chamber 5 is switched on or off, but rather it is possible to display the current operating state, such as a heating-up phase or a self-cleaning phase, by means of the illuminated display 8 , Also in the oven existing residual heat can be displayed or the completion of a cooking process by appropriate change of the light image. Additionally alternatively, it can be provided that a hob (is shown) of the cooking appliance is provided, and that the light indicator 8 indicates operating conditions of the hob, such. B. that a certain temperature or a defined state of cooking is reached.

Die Länge der Leuchtanzeige 8 entspricht bei der dargestellten Ausführungsform in etwa der Breite des Sichtfensters 4a der den Garraum 5 verschließenden Tür 4, wodurch ein klarer Bezug der Leuchtanzeige 8 zur Funktion des Garraums 5 hergestellt wird.The length of the light indicator 8 corresponds in the illustrated embodiment, approximately the width of the viewing window 4a of the cooking chamber 5 closing door 4, whereby a clear reference of the light indicator 8 is made to the function of the cooking chamber 5.

Bei der in Fig. 2 dargestellten Anzeigesituation der Leuchtanzeige 8 leuchtet ein erster Abschnitt 8a der Leuchtanzeige 8 mit Dauerlicht, während das Licht eines zweiten Abschnitts 8b blinkt. Diese Anzeigesituation zeigt an, dass sich der Garraum 5 in der Aufheizphase befindet, wobei das Dauerlicht des ersten Abschnitts 8a den Bereich der bereits erreichten Temperatur anzeigt und der blinkende zweite Abschnitt 8b den noch aufzuheizenden Temperaturbereich verdeutlicht.In the display situation of the illuminated display 8 shown in FIG. 2, a first section 8a of the illuminated display 8 illuminates with continuous light, while the light of a second section 8b flashes. This display situation indicates that the cooking chamber 5 is in the heating phase, wherein the continuous light of the first section 8a indicates the range of the already reached temperature and the flashing second section 8b illustrates the still aufheizenden temperature range.

Wie weiterhin aus Fig. 2 ersichtlich, ist bei der dargestellten Ausführungsform die Leuchtanzeige 8 zusätzlich mit einer Temperaturskala 9 ausgestattet, der der Benutzer des Gargeräts die exakte, durch das Leuchtband visualisierte Temperatur entnehmen kann. Die Skala 9 ist durch eine der Leuchtanzeige 8 zugeordnete Bedruckung der Bedienblende 6 realisiert.As further seen in Fig. 2, in the illustrated embodiment, the light indicator 8 is additionally equipped with a temperature scale 9, which remove the user of the cooking device the exact, visualized by the light strip temperature can. The scale 9 is realized by one of the illuminated display 8 associated printing of the control panel 6.

Neben der dargestellten Möglichkeit, die Temperatur und/oder den Betriebszustand des Garraums 5 mittels der Leuchtanzeige 8 darzustellen, wird die Temperatur des Garraums 5 durch eine sich ändernde Farbe bzw. Farb- oder Lichtintensität dargestellt, so dass beispielsweise die Farbintensität oder die Leuchtkraft zunimmt, je höher die Temperatur des Garraums 5 ist, damit der Benutzer schon von weitem erkennen kann, ob die Tür 4 des Garraums 5 möglicherweise heiß ist. Ebenso kann ein Blinken der Leuchtanzeige 8 beispielsweise anzeigen, dass gerade die Selbstreinigungsphase des Garraums 5 läuft, bei der, insbesondere beim Pyrolyseverfahren, die Temperatur im Garraum 5 besonders hoch ist, so dass das Blinklicht eine Warnfunktion ausübt.In addition to the illustrated possibility to represent the temperature and / or the operating state of the cooking chamber 5 by means of the light display 8, the temperature of the cooking chamber 5 is represented by a changing color or color or light intensity, so that, for example, the color intensity or the luminosity increases, the higher the temperature of the cooking chamber 5, so that the user can already see from afar whether the door 4 of the cooking chamber 5 may be hot. Likewise, a flashing of the light indicator 8 indicate, for example, that just the self-cleaning phase of the cooking chamber 5 is running, in which, especially in pyrolysis, the temperature in the cooking chamber 5 is particularly high, so that the flashing light exerts a warning function.

Bei der in Figur 3 dargestellten zweiten Ausführungsform ist die Leuchtanzeige 8 als Schwellpfeil 10 ausgebildet. Wie aus der Darstellung ersichtlich, nimmt die beleuchtete Länge und Höhe des Schwellpfeils 10 mit steigender Temperatur zu, so dass ein eindeutiger optischer Eindruck über die Temperaturverhältnisse im Garraum 5 mittels dieser Anzeige vermittelbar ist. Zur Anzeige der exakten Garraumtemperatur ist die dargestellte Leuchtanzeige 8 zusätzlich mit einer digitalen Temperaturanzeige 11 versehen.In the second embodiment shown in Figure 3, the light indicator 8 is designed as a threshold arrow 10. As can be seen from the illustration, the illuminated length and height of the Schwellpfeils 10 increases with increasing temperature, so that a clear visual impression of the temperature conditions in the cooking chamber 5 can be communicated by means of this display. To display the exact cooking chamber temperature, the illustrated light indicator 8 is additionally provided with a digital temperature display 11.

Wie schließlich aus Figur 4 ersichtlich, kann die digitale Temperaturanzeige 11 auch mit dem linearen Leuchtband kombiniert werden, wie dies voranstehend zur Abbildung Figur 2 beschrieben wurde, so dass zusätzlich zu der Grobinformation über die Leuchtanzeige 8 der Benutzer des Gargeräts auch über die exakte Temperatur im Garraum 5 informiert wird.Finally, as can be seen from FIG. 4, the digital temperature display 11 can also be combined with the linear luminous band, as described above for the illustration in FIG. 2, so that in addition to the rough information about the luminous display 8, the user of the cooking appliance also knows about the exact temperature in FIG Cooking chamber 5 is informed.
