Description

Die vorliegende Erfindung betrifft ein GargerƤt sowie ein Verfahren zum Betreiben eines GargerƤts mit wenigstens einem durch wenigstens eine GarraumtĆ¼r verschlieƟbaren Garraum und mit wenigstens einer Heizeinrichtung zum Beheizen des Garraums und/oder zum Aussenden von Hochfrequenzstrahlung in den Garraum wƤhrend eines Garprozesses zur Zubereitung von Gargut.The present invention relates to a cooking appliance and to a method for operating a cooking appliance with at least one cooking chamber closable by at least one cooking chamber door and at least one heating device for heating the cooking chamber and / or emitting high-frequency radiation into the cooking chamber during a cooking process for the preparation of food.

Bei GarvorgƤngen entweicht in der Regel Feuchtigkeit aus dem Gargut. Nach Abschluss des Garvorgangs kann dadurch Kondensat an den entsprechend kalten WƤnden eines Garraums verbleiben. Verbleibendes Kondensat im Garraum wird hƤufig als unangenehm empfunden und kann zudem zur Korrosion fĆ¼hren.When cooking usually moisture escapes from the food. After completion of the cooking process, condensate can remain on the correspondingly cold walls of a cooking chamber. Remaining condensate in the cooking chamber is often perceived as unpleasant and can also lead to corrosion.

Entsprechend kĆ¼hle WƤnde bzw. GarrƤume kommen beispielsweise im Hochfrequenz- bzw. Mikrowellenbetrieb von MikrowellengerƤten und KombigerƤten vor. Beim Niedrigtemperaturgaren und Dampfgaren kann es ebenfalls zur Kondensatbildung im Garraum kommen, da in der Regel Garraumtemperaturen um die 100 Ā°C bzw. unter 100 Ā°C vorliegen.Correspondingly cool walls or cooking chambers occur, for example, in high-frequency or microwave operation of microwave ovens and combi appliances. During low-temperature cooking and steam cooking, condensate formation in the cooking chamber can also occur since, as a rule, oven temperatures are around 100 Ā° C. or below 100 Ā° C.

Aber auch in aufgeheizten GarrƤumen kann es zur Kondensation von Feuchte kommen, wenn die Taupunkttemperatur unterschritten wird. Das ist z. B. der Fall, wenn die Wand- oder Bauteiltemperaturen zu gering sind, um die aus dem Gargut entweichende Feuchte bzw. die durch gezielte Beschwadung zugefĆ¼hrte Feuchte in der Gasphase zu halten.But even in heated cooking rooms, moisture condensation may occur if the dew point temperature is not reached. This is z. As is the case when the wall or component temperatures are too low to keep the moisture escaping from the food or the supplied by targeted Beschwadung moisture in the gas phase.

Es ist daher die Aufgabe der vorliegenden Erfindung, eine verbesserte und insbesondere benutzerfreundliche Mƶglichkeit zur VerfĆ¼gung zu stellen, mit welcher das nach einem Garvorgang im Garraum verbliebene Kondensat aus dem Garraum entfernt werden kann.It is therefore the object of the present invention to provide an improved and in particular user-friendly option with which the condensate left in the cooking chamber after a cooking process can be removed from the cooking chamber.

Diese Aufgabe wird gelƶst durch ein GargerƤt mit den Merkmalen des Anspruchs 1 sowie durch ein Verfahren den Merkmalen des Anspruchs 12. Bevorzugte Merkmale sind Gegenstand der UnteransprĆ¼che. Weitere Vorteile und Merkmale ergeben sich aus der allgemeinen Beschreibung der Erfindung und der Beschreibung der AusfĆ¼hrungsbeispiele.This object is achieved by a cooking appliance with the features of claim 1 and by a method the features of claim 12. Preferred features are the subject of the dependent claims. Further advantages and features will become apparent from the general description of the invention and the description of the embodiments.

Das erfindungsgemƤƟe GargerƤt umfasst wenigstens einen durch wenigstens eine GarraumtĆ¼r verschlieƟbaren Garraum. Das GargerƤt umfasst wenigstens eine Heizeinrichtung zum Beheizen des Garraums und/oder zum Aussenden von Hochfrequenzstrahlung in den Garraum wƤhrend eines Garprozesses zur Zubereitung von Gargut. Dabei umfasst das GargerƤt wenigstens eine Trocknungseinrichtung. Die Trocknungseinrichtung ist dazu geeignet und ausgebildet, nach Beendigung des Garprozesses wenigstens ein Nachlaufprogramm auszufĆ¼hren, bei dem im Garraum angesammeltes Kondensat mittels der Heizeinrichtung wenigstens teilweise und vorzugsweise vollstƤndig verdampft und aus dem Garraum abgefĆ¼hrt wird. Die Trocknungseinrichtung ist dazu geeignet und ausgebildet, das Nachlaufprogramm nur dann auszufĆ¼hren, wenn mittels wenigstens einer Ɯberwachungseinrichtung festgestellt wird, dass sich kein Gargut im Garraum befindet und dass die GarraumtĆ¼r verschlossen ist.The cooking appliance according to the invention comprises at least one cooking chamber which can be closed by at least one cooking chamber door. The cooking appliance comprises at least one heating device for heating the cooking chamber and / or for emitting high-frequency radiation into the cooking chamber during a cooking process for the preparation of food to be cooked. This includes the cooking appliance at least one drying device. The drying device is suitable and designed, after completion of the cooking process, to carry out at least one overrun program in which condensate accumulated in the cooking chamber is at least partially and preferably completely evaporated by the heating device and removed from the cooking chamber. The drying device is suitable and designed to execute the follow-up program only if it is determined by means of at least one monitoring device that no food to be cooked is in the oven and that the cooking chamber door is closed.

Das erfindungsgemƤƟe GargerƤt bietet viele Vorteile. Ein erheblicher Vorteil ist, dass durch das Nachlaufprogramm das nach dem Garvorgang verbliebene Kondensat besonders benutzerfreundlich und komfortabel aus dem Garraum entfernt wird. So steht nach der Zubereitung von Speisen schnell und einfach wieder ein trockener und ansehnlicher Garraum zur VerfĆ¼gung. Ein Auswischen oder lang andauerndes Nachtrocknen sind nicht nƶtig. Besonders vorteilhaft ist auch, dass das Nachlaufprogramm nicht ausgefĆ¼hrt wird, wenn sich z. B. noch Gargut im Garraum befindet. So bleibt die gewĆ¼nschte Zubereitung des Lebensmittels erhalten und wird nicht durch das Nachlaufprogramm beeinflusst. Zudem ist die erfindungsgemƤƟe Kondensatentfernung besonders energieschonend und sicher, da das Nachlaufprogramm nicht ausgefĆ¼hrt wird, wenn die GarraumtĆ¼r z. B. noch geƶffnet ist.The cooking appliance according to the invention offers many advantages. A significant advantage is that the post-cooking program, the condensate remaining after the cooking process is removed very user-friendly and comfortable from the oven by the follow-up program. Thus, after the preparation of food is quickly and easily again a dry and sizable cooking space available. A wiping out or long-term drying is not necessary. It is also particularly advantageous that the tracking program is not executed when z. B. still food in the oven is located. This preserves the desired preparation of the food and is not affected by the follow-up program. In addition, the condensate removal according to the invention is particularly energy-saving and safe because the follow-up program is not performed when the cooking chamber door z. B. is still open.

Vorzugsweise umfasst die Ɯberwachungseinrichtung wenigstens ein Sensormittel zum Erkennen einer geƶffneten und/oder verschlossenen GarraumtĆ¼r. Das bietet eine zuverlƤssige und unaufwendige Mƶglichkeit, eine verschlossene TĆ¼r fĆ¼r das Nachlaufprogramm zu gewƤhrleisten. Das Sensormittel umfasst beispielsweise wenigstens einen TĆ¼rsensor und/oder wenigstens einen TĆ¼rkontaktschalter. Es kann auch ein anderes geeignetes Sensormittel vorgesehen sein.Preferably, the monitoring device comprises at least one sensor means for detecting an open and / or closed cooking chamber door. This provides a reliable and inexpensive way to ensure a locked door for the follow-up program. The sensor means comprises, for example, at least one door sensor and / or at least one door contact switch. It may also be provided another suitable sensor means.

Die Ɯberwachungseinrichtung ist vorzugsweise dazu geeignet und ausgebildet, mittels wenigstens einer Kameraeinrichtung ein Vorhandensein und/oder ein Fehlen von Gargut im Garraum zu erkennen. So kann zuverlƤssig und unaufwendig sichergestellt werden, dass kein Gargut im Garraum ist. Beispielsweise ist die Ɯberwachungseinrichtung dazu geeignet und ausgebildet, wenigstens eine Aufnahme des Garraums wƤhrend des Garprozesses mit wenigstens einer Aufnahme des Garraums nach Beendigung des Garprozesses zu vergleichen. Die Ɯberwachungseinrichtung kann fĆ¼r den Vergleich auch wenigstens eine Aufnahme des Garraums vor Beginn des Garprozesses heranziehen. Die Ɯberwachungseinrichtung ist insbesondere dazu geeignet und ausgebildet, anhand des Vergleichs der Aufnahmen miteinander das Vorhandensein und/oder Fehlen des Garguts im Garraum zu registrieren. Mƶglich ist auch, dass die Ɯberwachungseinrichtung dazu geeignet und ausgebildet ist, wenigstens eine Aufnahme nach Beendigung des Garprozesses mit wenigstens einer Referenzaufnahme und/oder mit geeigneten Referenzwerten zu vergleichen und anhand des Vergleichs ein Vorhandensein und/oder Fehlen des Garguts im Garraum zu erkennen. Die Aufnahme wird insbesondere mit der Kameraeinrichtung erstellt.The monitoring device is preferably suitable and designed to detect by means of at least one camera device a presence and / or a lack of food to be cooked in the cooking chamber. This makes it possible to reliably and inexpensively ensure that no food is in the oven. For example, the monitoring device is suitable and designed to compare at least one shot of the cooking chamber during the cooking process with at least one recording of the cooking chamber after completion of the cooking process. The monitoring device can also use at least one receptacle of the cooking chamber before the start of the cooking process for the comparison. The monitoring device is particularly suitable and designed to register the presence and / or absence of the food in the cooking chamber on the basis of the comparison of the recordings. It is also possible that the monitoring device is suitable and designed to at least one recording after completion of the cooking process with at least one Reference record and / or to compare with suitable reference values and to detect a presence and / or absence of the food in the cooking chamber based on the comparison. The recording is created in particular with the camera device.

Die Kameraeinrichtung ist vorzugsweise dazu geeignet und ausgebildet, Aufnahmen im sichtbaren WellenlƤngenbereich und/oder im Infrarotbereich des Lichts zu erfassen. Die Kameraeinrichtung umfasst insbesondere wenigstens einen Bildsensor und/oder anderen geeigneten Sensor. Die Ɯberwachungseinrichtung ist insbesondere dazu geeignet und ausgebildet, mittels wenigstens einer Software und/oder wenigstens eines hinterlegten Algorithmus wenigstens eine Bildanalyse der erfassten Aufnahmen bzw. Bilddaten durchzufĆ¼hren.The camera device is preferably suitable and designed to record images in the visible wavelength range and / or in the infrared range of the light. The camera device comprises in particular at least one image sensor and / or other suitable sensor. The monitoring device is in particular suitable and designed to carry out at least one image analysis of the recorded images or image data by means of at least one software and / or at least one stored algorithm.

In einer vorteilhaften Ausgestaltung ist die Ɯberwachungseinrichtung dazu geeignet und ausgebildet, mittels wenigstens einer Hochfrequenzsensoreinrichtung ein Vorhandensein und/oder ein Fehlen von Gargut im Garraum zu erkennen. Auch das bietet eine zuverlƤssige Mƶglichkeit, den Garraum auf ein Vorhandensein von Gargut zu kontrollieren. Insbesondere ist die Hochfrequenzsensoreinrichtung dazu geeignet und ausgebildet, in den Garraum gesendete und/oder aus dem Garraum empfangene Hochfrequenzstrahlung zu analysieren. Insbesondere ist die Hochfrequenzsensoreinrichtung dazu geeignet und ausgebildet, eine aus einem leeren Garraum reflektierte Hochfrequenzstrahlung von einer aus einem beladenen Garraum reflektierten Hochfrequenzstrahlung zu unterscheiden. Insbesondere ist die Hochfrequenzsensoreinrichtung dazu geeignet und ausgebildet, Hochfrequenzstrahlung zu erzeugen und in den Garraum zu senden.In an advantageous embodiment, the monitoring device is suitable and designed to detect by means of at least one high-frequency sensor device, a presence and / or a lack of food in the cooking chamber. This also provides a reliable way to control the cooking chamber for the presence of food. In particular, the high-frequency sensor device is suitable and designed to analyze high-frequency radiation transmitted into the cooking chamber and / or received from the cooking chamber. In particular, the high-frequency sensor device is suitable and designed to distinguish a high-frequency radiation reflected from an empty cooking chamber from a high-frequency radiation reflected from a loaded cooking chamber. In particular, the high-frequency sensor device is suitable and designed to generate high-frequency radiation and to send it into the cooking chamber.

Beispielsweise ist die Hochfrequenzsensoreinrichtung als ein Beladungssensor bzw. sogenannter No-Load-Sensor ausgebildet bzw. oder umfasst wenigstens einen solchen. No-Load-Sensoren werden beispielsweise bei MikrowellengargerƤten eingesetzt, um den Mikrowellenerzeuger vor BeschƤdigungen durch reflektierte Strahlung aus leeren GarrƤumen zu schĆ¼tzen.For example, the high-frequency sensor device is designed as a load sensor or so-called no-load sensor or at least includes one. For example, no-load sensors are used in microwave cooking appliances to protect the microwave generator from being damaged by reflected radiation from empty cooking chambers.

Die Ɯberwachungseinrichtung kann auch dazu geeignet und ausgebildet sein, mittels wenigstens einer Benutzereingabe ein Vorhandensein und/oder ein Fehlen von Gargut im Garraum zu erkennen. Beispielsweise kann der Benutzer die Benutzereingabe Ć¼ber eine Bedieneinrichtung eingeben. Das ermƶglicht eine besonders unaufwendige und zugleich sehr zuverlƤssige Mƶglichkeit, das Vorhandensein von Gargut im Garraum zu Ć¼berprĆ¼fen. Insbesondere ist die Ɯberwachungseinrichtung dazu geeignet und ausgebildet, mittels wenigstens einer Anzeigeeinrichtung, z. B. mit einem Display, eine Aufforderung zum Vornehmen der Benutzereingabe anzuzeigen. Beispielsweise wird Ć¼ber die Anzeigeeinrichtung eine Frage ausgegeben, ob noch Gargut im Garraum vorhanden ist oder nicht. Dabei besteht die Mƶglichkeit, durch eine entsprechende Eingabe, beispielsweise Ć¼ber Bedienelemente oder Ć¼ber eine Anzeige mit einer berĆ¼hrungsempfindlichen OberflƤche bzw. Touchscreen, diese Frage mit Ja oder Nein zu beantworten.The monitoring device may also be suitable and designed to recognize by means of at least one user input a presence and / or a lack of food in the cooking chamber. For example, the user may enter the user input via an operating device. This allows a particularly inexpensive and at the same time very reliable way to check the presence of food in the oven. In particular, the monitoring device is suitable and designed by means of at least one display device, for. B. with a display, a request to make the user input. For example, via the display device issued a question as to whether or not food is still present in the oven. It is possible to answer this question with a yes or no by an appropriate input, for example via controls or via a display with a touch-sensitive surface or touchscreen.

In einer bevorzugten Ausgestaltung ist die Trocknungseinrichtung dazu geeignet und ausgebildet, das Nachlaufprogramm automatisch und/oder nach wenigstens einer Benutzereingabe auszufĆ¼hren. Eine automatische AusfĆ¼hrung und/oder eine manuell gewƤhlte AusfĆ¼hrung des Nachlaufprogramms kann insbesondere manuell unterbrochen und/oder beendet werden. Das automatische AusfĆ¼hren ist besonders komfortabel fĆ¼r den Benutzer. Es kann vorgesehen sein, dass die automatische AusfĆ¼hrung durch wenigstens eine Benutzereingabe deaktivierbar und/oder aktivierbar ist. Beispielsweise kann eine grundsƤtzliche bzw. dauerhafte Aktivierung bzw. Deaktivierung und/oder Anpassung des Nachlaufprogramms eingestellt werden. Vorzugsweise wird die Benutzereingabe in der Trocknungseinrichtung hinterlegt und steht auch bei einem erneuten Betrieb bzw. erneuten Garprozess zur VerfĆ¼gung. Dadurch muss der Benutzer nicht immer eine erneute Deaktivierung bzw. Aktivierung oder Anpassung vornehmen.In a preferred embodiment, the drying device is suitable and designed to execute the follow-up program automatically and / or after at least one user input. An automatic execution and / or a manually selected execution of the follow-up program can in particular be manually interrupted and / or terminated. The automatic execution is particularly comfortable for the user. It can be provided that the automatic execution can be deactivated and / or activated by at least one user input. For example, a fundamental or permanent activation or deactivation and / or adaptation of the follow-up program can be set. Preferably, the user input is stored in the drying device and is also available for a renewed operation or re-cooking process. As a result, the user does not always have to make a new deactivation or activation or adaptation.

Das Starten des Nachlaufprogramms nach der Benutzereingabe ist ebenfalls sehr komfortabel, da der Benutzer es nach Belieben ausfĆ¼hren kann. Insbesondere ist die Trocknungseinrichtung dazu geeignet und ausgebildet, die Benutzereingabe zum Starten des Nachlaufprogramms Ć¼ber wenigstens eine Anzeigeeinrichtung anzufordern. Beispielsweise kann eine Aufforderung zur Benutzereingabe nach Beendigung eines Garprozesses automatisch angezeigt werden. Mƶglich ist auch, dass der Benutzer von sich aus eine Benutzereingabe vornehmen muss.Starting the post-cursor program after the user input is also very convenient, as the user can do it at will. In particular, the drying device is suitable and designed to request the user input for starting the follow-up program via at least one display device. For example, a request for user input after completion of a cooking process can be displayed automatically. It is also possible that the user has to make a user input on his own.

Bevorzugt ist die Trocknungseinrichtung dazu geeignet und ausgebildet, das Nachlaufprogramm wenigstens dann automatisch auszufĆ¼hren, wenn eine automatische AusfĆ¼hrung des Nachlaufprogramms in einem zuvor ausgefĆ¼hrten Programm hinterlegt ist. Das ist besonders komfortabel, da lediglich ein Garprogramm ausgewƤhlt werden muss, um die gewĆ¼nschten Speisen zuzubereiten und im Nachgang findet die Entfernung des Kondensats automatische statt. Eine unnƶtige AusfĆ¼hrung kann dadurch vermieden werden, sodass Energie eingespart wird. Vorzugsweise ist der beendete Garprozess dabei wenigstens ein Teil des Garprogramms und/oder mit diesem verknĆ¼pft. Insbesondere ist ein manuelles AusfĆ¼hren und/oder unterbrechen und/oder beenden des Nachlaufprogramms unabhƤngig von dem Garprogramm mƶglich.Preferably, the drying device is suitable and designed to execute the follow-up program automatically at least when an automatic execution of the follow-up program is stored in a previously executed program. This is particularly convenient, since only one cooking program has to be selected to prepare the desired food, and subsequently the removal of the condensate takes place automatically. An unnecessary execution can be avoided thereby, so that energy is saved. Preferably, the finished cooking process is at least part of the cooking program and / or associated with this. In particular, a manual execution and / or interrupting and / or terminating the follow-up program is possible independently of the cooking program.

Es kann vorgesehen sein, dass die Trocknungseinrichtung dazu geeignet und ausgebildet ist, je nach Garprogramm wenigstens einen Programmparameter fĆ¼r das Nachlaufprogramm anzupassen. Beispielsweise kann bei Garprogrammen, bei denen viel Feuchtigkeit aus dem Gargut austreten kann und mit entsprechend viel Kondensat zu rechnen ist, die Dauer und/oder IntensitƤt der mittels der Heizeinrichtung durchgefĆ¼hrten Verdampfung angepasst werden. Beispielsweise kann als Garprogramm mit einem automatisch ausgefĆ¼hrten Nachlaufprogramm ein Dampfgarprogramm, Niedertemperaturgarprogramm, Hochfrequenzgarprogramm, Garprogramm mit Beschwadung und/oder ein sonstiges Garprogramm mit einer hohen zu erwartenden Kondensatmenge vorgesehen sein. Insbesondere ist ein Garprogramm mit einem automatisch ausgefĆ¼hrten Nachlaufprogramm gekoppelt, wenn bei dem Garprogramm eine Temperatur der Garraumwandung unterhalb einer Siedetemperatur und/oder unterhalb einer Taupunkttemperatur bleibt.It may be provided that the drying device is suitable and designed, depending on the cooking program, at least one program parameter for the tracking program adapt. For example, in cooking programs in which a lot of moisture can escape from the food and be expected with a corresponding amount of condensate, the duration and / or intensity of the evaporation carried out by means of the heater can be adjusted. For example, as a cooking program with an automatically running follow-up program, a steam cooking program, low-temperature cooking program, high-frequency cooking program, cooking program with steaming and / or another cooking program with a high expected condensate quantity can be provided. In particular, a cooking program is coupled with an automatically running follow-up program, if in the cooking program a temperature of the cooking chamber wall remains below a boiling temperature and / or below a dew point temperature.

Vorzugsweise ist die Trocknungseinrichtung dazu geeignet und ausgebildet, das Nachlaufprogramm wenigstens dann automatisch auszufĆ¼hren, wenn mittels wenigstens einer Sensoreinrichtung eine Kondensatmenge oberhalb wenigstens eines Schwellenwertes sensiert wird. Das ist besonders komfortabel, da so das Kondensat ab einer bestimmten Menge automatisch entfernt wird. Das ist auch energetisch besonders sinnvoll, da ein unnƶtiges Beheizen vermieden wird, wenn das Kondensat bereits verdampft ist. Insbesondere ist ein manuelles AusfĆ¼hren und/oder Unterbrechen und/oder Beenden unabhƤngig von der Kondensatmenge mƶglich. Vorzugsweise ist die Trocknungseinrichtung dazu geeignet und ausgebildet, in AbhƤngigkeit einer erfassten Kondensatmenge wenigstens einen Programmparameter des Nachlaufprogramms anzupassen. Beispielsweise kƶnnen Dauer und/oder IntensitƤt der mittels der Heizeinrichtung durchgefĆ¼hrten Verdampfung angepasst werden. Der Schwellenwert ist insbesondere in der Trocknungseinrichtung hinterlegt. Der Schwellenwert kann durch eine Benutzereingabe wenigstens teilweise angepasst werden.Preferably, the drying device is suitable and designed to execute the follow-up program automatically at least if at least one sensor device senses a condensate amount above at least one threshold value. This is particularly convenient as it automatically removes the condensate above a certain amount. This is also energetically particularly useful because unnecessary heating is avoided when the condensate is already evaporated. In particular, a manual execution and / or interruption and / or termination is possible regardless of the amount of condensate. Preferably, the drying device is suitable and designed to adapt at least one program parameter of the tracking program as a function of a detected condensate quantity. For example, the duration and / or intensity of the evaporation carried out by means of the heating device can be adapted. The threshold value is stored in particular in the drying device. The threshold may be at least partially adjusted by user input.

Die Trocknungseinrichtung kann dazu geeignet und ausgebildet sein, wenigstens einen Programmparameter des Nachlaufprogramms in AbhƤngigkeit wenigstens einer Benutzereingabe und/oder einer sensorisch erfassten Kondensatmenge und/oder eines vorangegangenen Garprogramms wenigstens teilweise anzupassen. So kann das Nachlaufprogramm optimal auf die zu erwartende Kondensatmenge bzw. auf die WĆ¼nsche des Benutzers angepasst werden. Durch die Benutzereingabe kƶnnen beispielsweise die Dauer des Nachlaufprogramms und/oder die Dauer und/oder IntensitƤt der mittels der Heizeinrichtung durchgefĆ¼hrten Verdampfung einstellbar sein. Die Dauer des Nachlaufprogramms kann beispielsweise von einigen Sekunden bis zu einigen Minuten betragen. Die Dauer kann auch kĆ¼rzer oder lƤnger ausgestaltet sein.The drying device may be suitable and designed to at least partially adapt at least one program parameter of the follow-up program as a function of at least one user input and / or a sensory condensate quantity and / or a preceding cooking program. Thus, the follow-up program can be optimally adapted to the expected amount of condensate or to the wishes of the user. By the user input, for example, the duration of the follow-up program and / or the duration and / or intensity of the evaporation carried out by means of the heating device can be adjustable. The duration of the follow-up program can be, for example, from a few seconds to a few minutes. The duration can also be shorter or longer.

Es kann vorgesehen sein, dass der Programmparameter eine Dauer der Verdampfung und/oder eine zur Verdampfung eingesetzte Heizquelle und/oder eine zur Verdampfung eingestellte Heizleistung und/oder Hochfrequenzleistung vorgibt. Die Heizquelle umfasst insbesondere wenigstens eine thermische Heizquelle oder ist als eine solche ausgebildet. Die Heizeinrichtung kann auch wenigstens einen Hochfrequenzerzeuger bzw. eine Hochfrequenzheizquelle umfassen oder als eine solche ausgebildet sein. Der Hochfrequenzerzeuger dient insbesondere zum Einbringen von Hochfrequenzstrahlung in den Garraum, durch welche das Gargut gezielt erhitzt bzw. gegart werden kann. Solche Programmparameter bieten eine besonders gezielte Anpassung des Nachlaufprogramms. Es kƶnnen auch andere Programmparameter anpassbar sein.It can be provided that the program parameter has a duration of evaporation and / or a heat source used for evaporation and / or a vaporization set heating power and / or high frequency power. The heating source comprises in particular at least one thermal heating source or is designed as such. The heating device may also comprise or be designed as at least one high frequency generator or a high frequency heating source. The high-frequency generator is used in particular for introducing high-frequency radiation into the cooking chamber, through which the food can be heated or cooked specifically. Such program parameters offer a particularly targeted adaptation of the tracking program. Other program parameters may also be customizable.

Vorzugsweise ist die Trocknungseinrichtung dazu geeignet und ausgebildet, das Kondensat Ć¼ber wenigstens eine Auslasseinrichtung in die Umgebung des GargerƤts abzufĆ¼hren und/oder einer Trocknereinheit zum Trocknen von feuchter Luft zuzufĆ¼hren. Dadurch kann zuverlƤssig vermieden werden, dass das verdampfte Kondensat erneut im Garraum niederschlƤgt.Preferably, the drying device is suitable and designed to discharge the condensate via at least one outlet device into the environment of the cooking appliance and / or to supply it to a drying unit for drying moist air. This reliably prevents the evaporated condensate from reverberating in the cooking chamber.

Vorzugsweise ist die mit der Trocknereinheit getrocknete Luft Ć¼ber wenigstens eine Auslasseinrichtung in die Umgebung des GargerƤts abfĆ¼hrbar und/oder in den Garraum zurĆ¼ckfĆ¼hrbar. Das ist besonders vorteilhaft, da die getrocknete Luft keine unerwĆ¼nschten Feuchte-Emissionen in der Umgebung des GargerƤts und beispielsweise im KĆ¼chenraum verursacht. Das ZurĆ¼ckfĆ¼hren der getrockneten Luft ist ebenfalls vorteilhaft, da so unerwĆ¼nschte Feuchte-Emissionen vermieden und zugleich Energie zum Beheizen des Garraums gespart werden kann.Preferably, the dried with the dryer unit air via at least one outlet device in the environment of the cooking device can be discharged and / or traceable into the cooking chamber. This is particularly advantageous since the dried air does not cause undesirable moisture emissions in the environment of the cooking appliance and, for example, in the kitchen space. The return of the dried air is also advantageous because it avoids unwanted moisture emissions and at the same time energy can be saved for heating the cooking chamber.

Besonders bevorzugt ist die Trocknereinheit dazu geeignet und ausgebildet, die Luft auf eine Raumluftfeuchte zu trocknen. Die Raumluftfeuchte entspricht insbesondere einer relativen Luftfeuchtigkeit von weniger als 70 % und vorzugsweise weniger als 60 % und besonders bevorzugt weniger als 50 % insbesondere bei einer Raumtemperatur. Die Raumtemperatur liegt insbesondere bei 20 Ā°C. Es kann auch eine Raumtemperatur von 25 Ā°C angenommen werden. Dadurch herrscht im Garraum eine besonders gĆ¼nstige AtmosphƤre zur Zubereitung von Lebensmitteln. Zudem wird auch bei lƤngeren GarvorgƤngen die Raumluftfeuchte der KĆ¼che nicht ungĆ¼nstig erhƶht.Particularly preferably, the dryer unit is suitable and designed to dry the air to a room humidity. The room air humidity corresponds in particular to a relative humidity of less than 70% and preferably less than 60% and particularly preferably less than 50%, in particular at room temperature. The room temperature is especially at 20 Ā° C. It can also be assumed a room temperature of 25 Ā° C.

Zur KĆ¼hlung der Luft wird die Trocknereinheit vorzugsweise gekĆ¼hlt.The dryer unit may be suitable and designed to cool the air and in particular to cool it to a temperature below a room temperature. In particular, the dryer unit is suitable and designed to cool the air below 20 Ā° C and preferably below 15 Ā° C and more preferably below 10 Ā° C. It is also possible that the dryer unit is adapted to cool the air below 5 Ā° C. For cooling the air, the dryer unit is preferably cooled.

Insbesondere umfasst die Trocknereinheit wenigstens einen WƤrmetauscher, durch welchen die zu trocknende Luft gefĆ¼hrt wird. Der WƤrmetauscher kann durch wenigstens einen KĆ¼hlluftstrom und/oder mittels einer thermoelektrischen KĆ¼hleinrichtung, z. B. ein Peltierelement, kĆ¼hlbar sein. Insbesondere umfasst die Trocknereinheit zur KĆ¼hlung wenigstens eine KƤltemaschine und/oder wenigstens eine WƤrmepumpeneinrichtung und/oder wenigstens eine thermoelektrische KĆ¼hleinrichtung. Durch eine solche KĆ¼hlung kann die Luft auf ein besonders geringes MaƟ an Feuchte getrocknet werden.In particular, the dryer unit comprises at least one heat exchanger through which the air to be dried is guided. The heat exchanger can by at least one cooling air flow and / or by means of a thermoelectric cooling device, for. B. a Peltier element, be coolable. In particular, the dryer unit for cooling comprises at least one refrigerating machine and / or at least one heat pump device and / or at least one thermoelectric cooling device. By such cooling, the air can be dried to a particularly low level of moisture.

Es ist mƶglich, dass die Trocknungseinrichtung dazu geeignet und ausgebildet ist, das verdampfte Kondensat wenigstens einer Reinigungseinrichtung zuzufĆ¼hren. So kann nicht nur das Kondensat, sondern auch die in dem Kondensat bzw. in der Garraumluft enthaltenen Verschmutzungen aus dem Garraum entfernt werden. Die gereinigte Luft ist vorzugsweise Ć¼ber wenigstens eine Auslasseinrichtung in die Umgebung des GargerƤts abfĆ¼hrbar und/oder in den Garraum zurĆ¼ckfĆ¼hrbar. Die gereinigte Luft kann auch zu der Trocknereinheit gefĆ¼hrt werden. Insbesondere ist die Reinigungseinheit der Trocknereinheit vorgeschaltet. Dadurch wird eine Verschmutzung der Trocknereinheit durch im Kondensat enthaltene Substanzen zuverlƤssig vermieden. Die Reinigungseinheit umfasst beispielsweise wenigstens eine Katalysatoreinrichtung, welche Reaktionen zum Abbau von Fetten und/oder Ɩlen sowie von geruchsbelƤstigenden Stoffen des Wrasens katalysiert bzw. unterstĆ¼tzt. Die Reinigungseinheit kann auch wenigstens eine Wascheinrichtung mit wenigstens einer WaschflĆ¼ssigkeit umfassen.

So not only the condensate, but also the contaminants contained in the condensate or in the cooking chamber air can be removed from the oven. The cleaned air can preferably be discharged via at least one outlet device into the environment of the cooking appliance and / or can be returned to the cooking chamber. The cleaned air can also be fed to the dryer unit. In particular, the cleaning unit is connected upstream of the dryer unit.

WƤhrend wenigstens eines Garprozesses zur Zubereitung von Gargut wird mit wenigstens einer Heizeinrichtung der Garraum beheizt und/oder Hochfrequenzstrahlung in den Garraum gesendet. Dabei wird nach Beendigung des Garprozesses mittels wenigstens einer Trocknungseinrichtung wenigstens ein Nachlaufprogramm ausgefĆ¼hrt. Durch das Nachlaufprogramm wird im Garraum angesammeltes Kondensat mittels der Heizeinrichtung wenigstens teilweise und vorzugsweise vollstƤndig verdampft und aus dem Garraum abgefĆ¼hrt. Das Nachlaufprogramm wird nur dann ausgefĆ¼hrt, wenn mittels wenigstens einer Ɯberwachungseinrichtung festgestellt wird, dass sich kein Gargut im Garraum befindet und dass die GarraumtĆ¼r verschlossen ist.The inventive method is used to operate a cooking appliance with at least one closable by at least one cooking chamber door cooking chamber.

Die Figur 1 zeigt ein erfindungsgemƤƟes GargerƤt 1, welches hier als ein Backofen 100 bzw. KombigerƤt ausgefĆ¼hrt ist. Das GargerƤt wird nach dem erfindungsgemƤƟen Verfahren betrieben. Das GargerƤt 1 hat einen beheizbaren Garraum 11, welcher durch eine GarraumtĆ¼r 101 verschlieƟbar ist. Das GargerƤt 1 ist hier als ein EinbaugerƤt vorgesehen. Es kann auch als ein StandgerƤt ausgebildet sein.The FIG. 1 shows a cooking appliance 1 according to the invention, which is embodied here as a baking oven 100 or combi appliance. The cooking appliance is operated by the method according to the invention. The cooking appliance 1 has a heatable cooking chamber 11, which can be closed by a cooking chamber door 101. The cooking appliance 1 is provided here as a built-in appliance. It can also be designed as a state machine.

FĆ¼r die Beheizung des Garraums 11 ist hier eine Heizeinrichtung 2 mit verschiedenen thermischen Heizquellen 12 vorgesehen. Die Heizeinrichtung 2 kann auch zum Erhitzen bzw. Garen mit Hochfrequenzstrahlung ausgebildet sein und dazu insbesondere wenigstens einen Hochfrequenzerzeuger 22 umfassen. Als Heizquelle 12 kƶnnen beispielsweise eine Oberhitze 32, eine Unterhitze 42, eine HeiƟluftheizquelle 52 und/oder eine Grillheizquelle vorgesehen sein. Die Heizquellen 12 kƶnnen in Verbindung mit einem UmluftgeblƤse 103 einsetzbar sein.For heating the cooking chamber 11, a heating device 2 with different thermal heat sources 12 is provided here. The heating device 2 can also be designed for heating or cooking with high-frequency radiation and in particular comprise at least one high-frequency generator 22. For example, a top heat 32, a bottom heat 42, a hot air heat source 52 and / or a grill heat source may be provided as the heat source 12. The heating sources 12 may be used in conjunction with a circulating air blower 103.

Das GargerƤt 1 kann als ein KombigerƤt ausgebildet sein, bei dem das Gargut sowohl mit den thermischen Heizquellen 12 als auch durch den Hochfrequenzerzeuger 22 erhitzt werden kann. Das GargerƤt 1 bzw. das KombigerƤt kann mit einer Dampfgarfunktion ausgestattet sein. Dann ist wenigstens ein Dampferzeuger als Heizquelle 12 vorgesehen.The cooking appliance 1 can be designed as a combined appliance, in which the food can be heated both with the thermal heat sources 12 and by the high-frequency generator 22. The cooking appliance 1 or the combi appliance can be equipped with a steam cooking function. Then at least one steam generator is provided as the heating source 12.

Das GargerƤt 1 umfasst hier eine Steuereinrichtung 102 zur Steuerung bzw. Regelung von GerƤtefunktionen und BetriebszustƤnden. Ɯber die Steuereinrichtung 102 sind hier verschiedene Betriebsarten und vorzugsweise verschiedene Garprogramme bzw. Programmbetriebsarten und andere Automatikfunktionen ausfĆ¼hrbar.The cooking appliance 1 here comprises a control device 102 for controlling or regulating device functions and operating states. Via the control device 102 different operating modes and preferably different cooking programs or program operating modes and other automatic functions can be executed here.

Zur Bedienung des GargerƤtes 1 ist eine Bedieneinrichtung 104 vorgesehen. Beispielsweise kƶnnen darĆ¼ber die Betriebsart, die Garraumtemperatur und/oder ein Garprogramm bzw. eine Programmbetriebsart oder andere Automatikfunktion ausgewƤhlt und eingestellt werden. Ɯber die Bedieneinrichtung kƶnnen auch andere Benutzereingaben vorgenommen werden. Die Bedieneinrichtung 104 umfasst auch eine Anzeige, Ć¼ber die Benutzerhinweise und z. B. Eingabeaufforderungen angezeigt werden kƶnnen. Die Bedieneinrichtung 104 kann Bedienelemente und/oder eine berĆ¼hrungsempfindliche Anzeige bzw. einen Touchscreen umfassen.For operating the cooking appliance 1, an operating device 104 is provided. For example, the operating mode, the cooking chamber temperature and / or a cooking program or a program operating mode or another automatic function can be selected and set. Other user inputs can also be made via the operating device. The operating device 104 also includes a display via which user instructions and z. B. prompts can be displayed. The operating device 104 may include operating elements and / or a touch-sensitive display or a touchscreen.

Das GargerƤt umfasst hier eine Trocknungseinrichtung 3 zum Entfernen von Kondensat, welche sich nach einem Garprozess im Garraum 11 angesammelt hat. Die Trocknungseinrichtung 3 fĆ¼hrt dazu nach Beendigung des Garprozesses ein Nachlaufprogramm aus, bei dem das im Garraum 11 angesammelte Kondensat mittels der Heizeinrichtung 2 verdampft wird. Dazu ist die Trocknungseinrichtung 3 hier mit der Steuereinrichtung 102 des GargerƤts 1 wirkverbunden, um die Heizeinrichtung 2 entsprechend ansteuern zu kƶnnen.The cooking appliance here comprises a drying device 3 for removing condensate, which has accumulated in the cooking chamber 11 after a cooking process. After the cooking process has ended, the drying device 3 carries out a follow-on program in which the condensate accumulated in the cooking chamber 11 is vaporized by means of the heating device 2. For this purpose, the drying device 3 is operatively connected here to the control device 102 of the cooking device 1 in order to be able to correspondingly control the heating device 2.

Zum Verdampfen des Kondensats kann beispielsweise eine der Heizquellen 12 aktiviert werden. Zum Beispiel kƶnnen die Oberhitze 32, die Unterhitze 42 und/oder die HeiƟluftquelle 52, jeweils mit oder ohne UmluftgeblƤse 103, eingesetzt werden. Zum Verdampfen des Kondensats kann auch eine hier nicht gezeigte Heizquelle 12 eingesetzt werden, beispielsweise eine Grillheizquelle oder dergleichen.For example, one of the heating sources 12 can be activated to evaporate the condensate. For example, the top heat 32, the bottom heat 42, and / or the hot air source 52, each with or without circulating air blower 103, may be used. For evaporating the condensate can also be used a heating source 12, not shown here, for example, a Grillheizquelle or the like.

ZusƤtzlich zu den Heizquellen 12 kann die Heizeinrichtung 2 zum Verdampfen des Kondensats auch einen Hochfrequenzerzeuger 22 einsetzen. Zum Verdampfen des Kondensats kann auch ein reiner Hochfrequenz-Betrieb mit definierter Leistung und Dauer vorgesehen sein. Der Hochfrequenzerzeuger 22 sendet Hochfrequenzstrahlung in den Garraum 11 und erhitzt dadurch das Kondensat bis zum Verdampfen. Das bietet eine besonders energieschonende Verdampfung, da nicht der gesamte Garraum 11 bzw. dessen WƤnde aufgeheizt werden mĆ¼ssen.In addition to the heat sources 12, the heater 2 may also use a high frequency generator 22 to evaporate the condensate. To evaporate the condensate, a pure high-frequency operation with defined power and duration can be provided. The high-frequency generator 22 sends high-frequency radiation into the cooking chamber 11 and thereby heats the condensate until it evaporates. This offers a particularly energy-saving Evaporation, since not the entire cooking chamber 11 or its walls must be heated.

Das verdampfte Kondensat bzw. der beim Erhitzen entstandene Wrasen werden hier aus dem Garraum 11 abgefĆ¼hrt. Dazu ist in der hier gezeigten Ausgestaltung eine Auslasseinrichtung 5 vorgesehen, welche eine Strƶmungsverbindung zwischen dem Garraum 11 und der Umgebung des GargerƤts 1 herstellt. Die Auslasseinrichtung 5 kann eine Ventileinrichtung 33 umfassen, um die Strƶmungsverbindung automatisiert ƶffnen und/oder schlieƟen zu kƶnnen. Zudem kann der Strƶmungsverbindung eine GeblƤseeinrichtung 23 zugeordnet sein, durch welche die Luft aus dem GargerƤt 1 geblasen werden kann. Beispielsweise ist die GeblƤseeinrichtung 23 nur dann aktiv, wenn im Rahmen des Nachlaufprogramms das verdampfte Kondensat abgefĆ¼hrt werden soll. Dazu ist die GeblƤseeinrichtung 23 insbesondere durch die Trocknungseinrichtung 3 ansteuerbar.The vaporized condensate or the vapor formed on heating are removed from the cooking chamber 11 here. For this purpose, an outlet device 5 is provided in the embodiment shown here, which produces a flow connection between the cooking chamber 11 and the surroundings of the cooking appliance 1. The outlet device 5 may comprise a valve device 33 in order to be able to open and / or close the flow connection automatically. In addition, the flow connection can be associated with a blower device 23, through which the air can be blown out of the cooking appliance 1. For example, the blower device 23 is only active if the vaporized condensate is to be removed in the course of the follow-up program. For this purpose, the blower device 23 can be controlled in particular by the drying device 3.

ZusƤtzlich oder alternativ zu der GeblƤseeinrichtung 23 kann auch das UmluftgeblƤse 103 zum Fƶrdern der Luft durch die Auslasseinrichtung 5 eingesetzt werden. Dann ist insbesondere die Ventileinrichtung 33 vorgesehen, um die Strƶmungsverbindung zu schlieƟen, wenn keine Luft abgefĆ¼hrt werden soll.In addition or as an alternative to the blower device 23, the circulating-air blower 103 can also be used to convey the air through the outlet device 5. Then, in particular, the valve device 33 is provided to close the flow connection when no air is to be removed.

Die Trocknungseinrichtung 3 ist hier mit einer Ɯberwachungseinrichtung 4 wirkverbunden. Die Trocknungseinrichtung 3 fĆ¼hrt das Nachlaufprogramm nur dann aus, wenn die Ɯberwachungseinrichtung 4 feststellt, dass sich kein Gargut im Garraum 11 befindet und dass die GarraumtĆ¼r 101 verschlossen ist. Dazu umfasst die Ɯberwachungseinrichtung 4 hier einen TĆ¼rsensor 34, welcher beispielsweise als ein TĆ¼rkontaktschalter ausgebildet ist. DarĆ¼ber kann die Ɯberwachungseinrichtung 4 registrieren, ob die GarraumtĆ¼r 101 korrekt verschlossen ist oder nicht.The drying device 3 is operatively connected here to a monitoring device 4. The drying device 3 executes the follow-up program only when the monitoring device 4 determines that there is no food to be cooked in the cooking chamber 11 and that the cooking chamber door 101 is closed. For this purpose, the monitoring device 4 here comprises a door sensor 34, which is designed, for example, as a door contact switch. In addition, the monitoring device 4 can register whether the cooking chamber door 101 is correctly closed or not.

Zudem umfasst die Ɯberwachungseinrichtung 4 hier eine Kameraeinrichtung 14 und/oder eine Hochfrequenzsensoreinrichtung 24. Mit der Kameraeinrichtung 14 registriert die Ɯberwachungseinrichtung 4, ob im Garraum 11 Gargut vorhanden ist oder nicht. Dazu werden beispielsweise Aufnahmen des Garraums 11 erfasst und anschlieƟend im Rahmen einer Bildanalyse ausgewertet.In addition, the monitoring device 4 here comprises a camera device 14 and / or a high-frequency sensor device 24. With the camera device 14, the monitoring device 4 registers whether or not food is present in the cooking chamber 11. For this purpose, for example, recordings of the cooking chamber 11 are detected and then evaluated as part of an image analysis.

Die Hochfrequenzsensoreinrichtung 24 kann hier zusƤtzlich oder alternativ zu der Kameraeinrichtung 14 vorgesehen sein. Beispielsweise erkennt die Ɯberwachungseinrichtung 4 anhand eines von der Hochfrequenzsensoreinrichtung 24 erfassten Reflexionssignals aus dem Garraum 11, ob im Garraum 11 ein Gargut vorhanden ist bzw. ob der Garraum 11 leer ist oder nicht. Beispielsweise ist die Hochfrequenzeinrichtung 24 als ein Beladungssensor bzw. ein sogenannter No-Load-Sensor ausgebildet.The high-frequency sensor device 24 may be provided here additionally or alternatively to the camera device 14. For example, the monitoring device 4 recognizes from the cooking chamber 11, based on a reflection signal detected by the high-frequency sensor device 24, whether a cooking product is present in the cooking chamber 11 or whether the cooking chamber 11 is empty or not. For example, the high-frequency device 24 is designed as a load sensor or a so-called no-load sensor.

Die Ɯberwachungseinrichtung 4 kann auch mit der Bedieneinrichtung 104 wirkverbunden sein und Ć¼ber diese eine Benutzereingabe anfordern. Dabei wird von einem Benutzer eingegeben, ob noch Gargut im Garraum 11 vorhanden ist oder ob es bereits entnommen wurde.The monitoring device 4 can also be operatively connected to the operating device 104 and request a user input via this. It is entered by a user, if still food in the oven 11 is present or if it has already been removed.

Die Trocknungseinrichtung 3 kann in einer Ausgestaltung mit wenigstens einer Sensoreinrichtung 13 wirkverbunden sein. Die Sensoreinrichtung 13 umfasst beispielsweise einen im Garraum angeordneten Sensor. Mit dem Sensor erfasst die Sensoreinrichtung 13, ob im Garraum 11 eine Kondensatmenge oberhalb eines Schwellenwertes vorliegt oder nicht. Bei Erreichen bzw. Ɯberschreiten des Schwellenwertes fĆ¼hrt die Trocknungseinrichtung 3 dann das Nachlaufprogramm aus, um das Kondensat zu entfernen. Dabei kann die automatische AusfĆ¼hrung manuell beeinflusst, unterbrochen und/oder beendet werden.In one embodiment, the drying device 3 can be operatively connected to at least one sensor device 13. The sensor device 13 comprises, for example, a sensor arranged in the cooking chamber. With the sensor, the sensor device 13 detects whether or not there is a condensate amount in the cooking chamber 11 above a threshold value. Upon reaching or exceeding the threshold value, the drying device 3 then executes the follow-up program in order to remove the condensate. The automatic execution can be influenced, interrupted and / or stopped manually.

In einer Ausgestaltung kann die Sensoreinrichtung 13 auch dazu eingesetzt werden, die im Garraum 11 vorhandene Kondensatmenge zu erfassen, um in AbhƤngigkeit der erfassten Kondensatmenge einen oder mehrere Programmparameter des Nachlaufprogramms anzupassen. Beispielsweise kƶnnen die Dauer oder die Art der Heizquelle oder auch die IntensitƤt der Beheizung angepasst werden.In one embodiment, the sensor device 13 can also be used to detect the amount of condensate present in the cooking chamber 11 in order to adapt one or more program parameters of the follow-up program as a function of the detected condensate quantity. For example, the duration or the type of heat source or the intensity of the heating can be adjusted.

In der Figur 2 ist das GargerƤt 1 mit einer Trocknungseinrichtung 3 gezeigt, welche hier mit einer Trocknereinheit 6 zum Trocknen der Luft bzw. des Wrasens im Garraum 11 ausgestattet ist. Beispielsweise kann bis auf ein Raumluftniveau getrocknet werden. Die Trocknereinheit 6 entnimmt dem Garraum 11 die Luft hier Ć¼ber eine Vorlaufleitung 16. Nach dem Trocknen kann die getrocknete Luft Ć¼ber eine RĆ¼cklaufleitung 26 wieder in den Garraum 11 zurĆ¼ckgefĆ¼hrt werden.In the FIG. 2 the cooking appliance 1 is shown with a drying device 3, which is equipped here with a dryer unit 6 for drying the air or the Wrasens in the cooking chamber 11. For example, it can be dried to a room air level. The drying unit 6 takes the cooking chamber 11, the air here via a feed line 16. After drying, the dried air can be recycled via a return line 26 back into the cooking chamber 11.

Alternativ oder zusƤtzlich zu der RĆ¼cklaufleitung 26 kann die Trocknereinheit 6 auch eine Auslasseinrichtung 5 umfassen, um die getrocknete Luft in die Umgebung des GargerƤts 1 abzufĆ¼hren.Alternatively or in addition to the return line 26, the dryer unit 6 may also include an outlet device 5 to discharge the dried air into the environment of the cooking appliance 1.

Die Trocknereinheit 6 kann die in der Luft enthaltene Feuchtigkeit wenigstens teilweise kondensieren. FĆ¼r das Kondensat kann ein SammelbehƤlter und/oder eine AbfĆ¼hreinrichtung vorgesehen sein. Die AbfĆ¼hreinrichtung kann beispielsweise an ein Abwassersystem angeschlossen sein.The dryer unit 6 may at least partially condense the moisture contained in the air. For the condensate can be provided a collecting container and / or a discharge device. The discharge device may be connected, for example, to a sewer system.

Zum Fƶrdern der feuchten Luft aus dem Garraum 11 bzw. der getrockneten Luft kann die Trocknereinheit 6 mit einer hier nicht nƤher dargestellten GeblƤseeinrichtung ausgestattet sein. ZusƤtzlich oder alternativ zu der GeblƤseeinrichtung kann auch das UmluftgeblƤse 103 zum Fƶrdern der Luft eingesetzt werden. Dann sind vorzugsweise die Vorlaufleitung 16 und/oder die RĆ¼cklaufleitung 26 und/oder die Auslasseinrichtung 5 mit wenigstens einer steuerbaren Ventileinrichtung 33 ausgestattet.For conveying the moist air from the cooking chamber 11 or the dried air, the dryer unit 6 may be equipped with a blower device, not shown here. In addition or as an alternative to the blower device, the circulating-air blower 103 can also be used to convey the air. Then preferably the flow line 16 and / or the Return line 26 and / or the outlet 5 equipped with at least one controllable valve device 33.

Die Trocknereinheit 6 kann hier mit einem WƤrmetauscher 36 ausgestattet sein. Dabei kann der WƤrmetauscher 14 durch einen KĆ¼hlluftstrom gekĆ¼hlt werden, welcher mittels wenigstens einer GeblƤseeinrichtung 12 erzeugt wird. Die Trocknereinheit 4 kann in einer Ausgestaltung wenigstens eine thermoelektrische KĆ¼hleinrichtung 24 umfassen, beispielsweise ein Peltierelement. Die Trocknereinheit 4 kann alternativ oder zusƤtzlich auch mit einer WƤrmepumpeneinrichtung 34 ausgestattet sein. Mit der KĆ¼hleinrichtung 24 bzw. der WƤrmepumpeneinrichtung 34 kƶnnen die zu trocknende Luft bzw. der WƤrmetauscher 14 entsprechend gekĆ¼hlt werden. Eine solche KĆ¼hlung kann alternativ oder ergƤnzend zu dem KĆ¼hlluftstrom vorgesehen sein. Der WƤrmetauscher 14 kann auch mit einer FlĆ¼ssigkeit kĆ¼hlbar sein.The dryer unit 6 can be equipped here with a heat exchanger 36. In this case, the heat exchanger 14 can be cooled by a cooling air flow, which is generated by means of at least one blower device 12. In one embodiment, the dryer unit 4 may comprise at least one thermoelectric cooling device 24, for example a Peltier element. The dryer unit 4 may alternatively or additionally be equipped with a heat pump device 34. With the cooling device 24 or the heat pump device 34, the air to be dried or the heat exchanger 14 can be cooled accordingly. Such cooling may be provided as an alternative or in addition to the cooling air flow. The heat exchanger 14 may also be cooled with a liquid.

Die Trocknungseinrichtung 3 kann in einer Ausgestaltung mit einer Reinigungseinheit 7 ausgestattet sein, um das verdampfte Kondensat bzw. die Luft aus dem Garraum 11 von Fetten, Ɩlen, geruchsintensiven Stoffen und anderen Verunreinigungen zu befreien. Die Reinigungseinheit 7 umfasst zum Beispiel eine Katalysatoreinrichtung.In one embodiment, the drying device 3 can be equipped with a cleaning unit 7 in order to free the evaporated condensate or the air from the cooking chamber 11 from fats, oils, odorous substances and other impurities. The cleaning unit 7 comprises, for example, a catalyst device.

Die Trocknungseinrichtung 3 aktiviert das Nachlaufprogramm vorzugsweise nach Abschluss eines Garprozesses bzw. Garvorgangs in einer Betriebsart bzw. in einem Garprogramm, in denen bekannter Weise entsprechend viel Kondensat anfƤllt, dass ohne weitere Aktionen an den GarraumwƤnden verbleiben wĆ¼rde. GarvorgƤnge, bei den hƤufig Kondensat im Garraum verbleibt, sind zum Beispiel ein reiner Mikrowellenbetrieb (GarraumwƤnde sind kalt, Wasserdampf tritt aus dem Gargut und kondensiert) oder NiedrigtemperaturgarvorgƤnge mit externer Wasserdampfzufuhr (zum Beispiel Beschwadung bei Niedrigtemperaturgaren) oder Dampfgaren.The drying device 3 activates the follow-up program preferably after completion of a cooking process or cooking process in a mode or in a cooking program in which known manner correspondingly much condensate accumulates that would remain without further action on the cooking chamber walls. Cooking operations in which condensate often remains in the cooking chamber, for example, a pure microwave operation (cooking space walls are cold, steam comes out of the food and condensed) or NiedrigtemperaturgarvorgƤnge with external steam supply (for example, humidification at low temperature cooking) or steam cooking.

Der Abschluss des Garvorgangs ist z. B. durch Ablauf eines sensor- und/oder zeitgesteuerten Automatikprogramms oder durch die manuelle BetƤtigung der Bedieneinrichtung und beispielsweise eines Ausschaltelementes des GargerƤtes 1 gegeben. Dann wird das Nachlaufprogramm automatisch gestartet bzw. kann es manuell gestartet werden. Die Trocknereinrichtung 3 startet dann automatisch eine weitere Energiezufuhr zur Trocknung des Kondensats im Garraum 11.The completion of the cooking process is z. B. by the expiry of a sensor and / or time-controlled automatic program or by the manual operation of the operating device and, for example, a switch-off element of the cooking device 1 given. Then the follow-up program is started automatically or it can be started manually. The drying device 3 then automatically starts another energy supply for drying the condensate in the cooking chamber 11.

Dabei kann das Nachlaufprogramm durch eine erneute BetƤtigung des Ausschaltelementes oder durch eine erneute BetƤtigung der Bedieneinrichtung 104 und beispielsweise des Ausschaltelementes abgebrochen und beendet werden. Das Nachlaufprogramm kann auch grundsƤtzlich abgeschaltet werden, beispielsweise Ć¼ber eine Anwahl in den Einstellungen.In this case, the follow-up program can be interrupted and terminated by a renewed actuation of the switch-off element or by a renewed actuation of the operating device 104 and, for example, the switch-off element. The follow-up program can also be switched off in principle, for example via a selection in the settings.

Die AktivitƤt des GargerƤts 1 wƤhrend des Nachlaufprogramms kann hier in einer Anzeige bzw. in einem Display angezeigt werden. So ist der Benutzer darĆ¼ber informiert, was das GargerƤt 1 macht, obwohl es eigentlich ausgeschaltet sein sollte. Beispielsweise kann dabei die restliche Laufzeit des Nachlaufprogramms angezeigt werden.The activity of the cooking device 1 during the follow-up program can be displayed here in a display or in a display. Thus, the user is aware of what the cooking appliance 1 is doing, even though it should actually be off. For example, the remaining runtime of the follow-up program can be displayed.

Vor dem Starten des Nachlaufprogramms werden mittels der Ɯberwachungseinrichtung 4 bestimmte Bedingungen Ć¼berprĆ¼ft. Solche Bedingungen betreffen z. B. die Fragen: Wurde der letzte Garvorgang abgeschlossen? Handelte es sich dabei um einen Garvorgang, bei dem hƤufig Kondensat im Garraum verbleibt? Ist die TĆ¼r geschlossen? Befand sich beim letzten Garvorgang Gargut im Garraum 11? Wurde das Gargut aus dem Garraum 11 entnommen? Mit der Ɯberwachungseinrichtung 4 kƶnnen diese Fragen zuverlƤssig beantwortet werden.Before starting the follow-up program 4 certain conditions are checked by the monitoring device. Such conditions relate to z. For example, the questions: Was the last cooking process completed? Was this a cooking process that often leaves condensate in the cooking chamber? Is the door closed? Was there any food to be cooked in the cooking chamber 11 during the last cooking process? Was the food to be removed from the cooking chamber 11? With the monitoring device 4, these questions can be reliably answered.

Solange fertig gegartes Gargut im Garraum 11 ist, wƤre die Energiezufuhr wƤhrend des Nachlaufprogramms sehr nachteilig fĆ¼r die QualitƤt des Garguts. Daher ist es besonders vorteilhaft, dass das Nachlaufprogramm nicht gestartet wird, solange sich noch Gargut im Garraum 11 befindet. Beispielsweise kann sich fertig gegartes Gargut im Garraum 11 befinden, wenn nach einem Garprozess ein SchnellabkĆ¼hlen vorgesehen ist. Dann darf der Garraum 11 trotz des mƶglichen Kondensats nicht nachgeheizt werden, solange das Gargut noch im Garraum 11 ist. Das kann mit der Kameraeinrichtung 14 oder auch mit der Hochfrequenzsensoreinrichtung 22 besonders gut beobachtet werden. Das Nachlaufprogramm startet dann erst nach der Entnahme des Gargut.As long as finished cooked food in the cooking chamber 11, the energy supply during the follow-up program would be very detrimental to the quality of the food. Therefore, it is particularly advantageous that the follow-up program is not started as long as there is still food in the cooking chamber 11. For example, ready-cooked food can be located in the cooking chamber 11 when rapid cooling is provided after a cooking process. Then the cooking chamber 11 may not be reheated despite the possible condensate, as long as the food is still in the cooking chamber 11. This can be observed particularly well with the camera device 14 or also with the high-frequency sensor device 22. The follow-up program then starts only after the removal of the food.
