Description

Die vorliegende Erfindung betrifft ein Verfahren zum Betreiben eines Gargerätes nach dem Oberbegriff des Anspruchs 1.The present invention relates to a method for operating a cooking appliance according to the preamble of claim 1.

Gargeräte unterliegen einem ständigen Prozess der Weiterentwicklung, um den immer weiter steigenden Anforderungen bezüglich der Energieeffizienz zu genügen. Dazu wird insbesondere auch der Garraum von Gargeräten immer besser isoliert. Das hat zur Folge, dass die Temperatur im Garraum nur sehr langsam absinkt, selbst wenn die Heizkörper komplett ausgeschaltet werden.Cooking appliances are subject to a constant process of development in order to meet the ever-increasing requirements for energy efficiency. For this purpose, the cooking chamber of cooking appliances is getting better and better insulated. This has the consequence that the temperature in the cooking chamber sinks only very slowly, even if the radiators are completely switched off.

In manchen Situationen ist aber eben eine solche Temperaturstabilität nicht gewünscht oder sogar störend. Verfügt ein Gargerät zum Beispiel über eine Reinigungsfunktion mittels Pyrolyse, kann es unter Umständen sehr lange dauern, bis das Gargerät wieder betriebsbereit ist, da die Temperatur des Garraumes eine gewisse Temperatur unterschreiten muss, bis die Garraumtür wieder geöffnet werden kann. Dies schränkt den Bedienungskomfort ein.In some situations, however, just such a temperature stability is not desired or even disturbing. If a cooking appliance has, for example, a pyrolysis-based cleaning function, under certain circumstances it may take a long time for the cooking appliance to be ready for use again, since the temperature of the cooking chamber must fall below a certain temperature until the cooking-chamber door can be reopened. This limits the ease of use.

Aber auch bei normalen Garprozessen, wie zum Beispiel dem Backen eines Kuchens, kann das langsame Absinken der Garraumtemperatur unerwünscht sein. Hat das Backgut einen gewünschten Bräunungsgrad erreicht, stellen sich beispielsweise bei einer Programmautomatik die Heizkörper automatisch ab. Allerdings kann die nur langsam abnehmende Restwärme im Garraum zu einer weiteren unerwünschten Bräunung führen. Dadurch kann es im schlimmsten Fall dazu kommen, dass ein Lebensmittel durch eine zu starke Nachbräunung ungenießbar wird, wenn der Benutzer das Lebensmittel nicht zeitnah aus dem Ofen entnimmt oder zumindest die Garraumtür öffnet.But even with normal cooking processes, such as the baking of a cake, the slow sinking of the oven temperature may be undesirable. If the dough has reached a desired degree of browning, the radiators automatically turn off, for example, in the case of an automatic program. However, the only slowly decreasing residual heat in the cooking chamber can lead to a further undesirable browning. As a result, it can happen in the worst case that a food is inedible by excessive browning, if the user does not promptly remove the food from the oven or at least the cooking chamber door opens.

Auch innerhalb eines Garprozesses kann es vorteilhaft sein, den Garraum schnell abzukühlen. Nutzt man beispielsweise einen Backofen zum Anbraten eines Bratens, muss dieser zunächst sehr heiß betrieben werden, um eine Kruste mit einer gewünschten Bräunung zu erreichen. Anschließend muss der Garraum allerdings schnell auf eine relativ niedrige Temperatur abgesenkt werden, um den Braten mit einer Niedergartemperatur für mehrere Stunden im Garraum weiter zu garen. Auch in einem solchen Fall muss der Benutzer aktiv in den Garprozess eingreifen und zum Beispiel die Tür des Garraumes öffnen, um den Garraum abzukühlen.Even within a cooking process, it may be advantageous to cool the oven quickly. If, for example, an oven is used to roast a roast, it must first be run very hot in order to achieve a crust with a desired browning. Subsequently, however, the cooking space must be lowered quickly to a relatively low temperature in order to continue to cook the roast with a low temperature for several hours in the oven. Even in such a case, the user must actively intervene in the cooking process and, for example, open the door of the cooking chamber to cool the cooking chamber.

Ein solches Eingreifen ist für einen Benutzer lästig. Außerdem kann das Eingreifen in den Garprozess, zum Beispiel das Öffnen der Tür, auch leicht vergessen werden oder ist in manchen Situationen nicht möglich, wenn der Benutzer gerade andere Dinge zu erledigen hat. Dadurch kann das Garergebnis stark verschlechtert werden.Such intervention is annoying for a user. In addition, the intervention in the cooking process, for example opening the door, can also be easily forgotten or in some situations not possible when the user is about to do other things. As a result, the cooking result can be greatly deteriorated.

Zum automatischen Abkühlen des Garraumes beschreibt zum Beispiel die DE 10327420 A1 die Verwendung einer Beschwadungsvorrichtung. Mittels der Beschwadungsvorrichtung wird Flüssigkeit auf das Lüfterrad der Gebläseeinrichtung des Gargerätes geleitet, wodurch durch die Drehbewegung des Lüfterrades kleine Flüssigkeitströpfchen in den Garraum eingebracht werden. Durch die Verdampfungskälte der Tröpfchen wird der Garraum abgekühlt. Nachteilig an einer solchen Methode zum Abkühlen des Garraumes ist allerdings, dass die Luftfeuchte des Garraumes erheblich verändert wird. Dies kann unter Umständen zu einer Verschlechterung des Garergebnisses führen.For automatic cooling of the cooking chamber describes, for example, the DE 10327420 A1 the use of a humidifier. By means of the Beschwadungsvorrichtung liquid is passed to the fan of the blower device of the cooking appliance, whereby small liquid droplets are introduced into the cooking chamber by the rotational movement of the fan wheel. Due to the evaporative cooling of the droplets, the cooking space is cooled. A disadvantage of such a method for cooling the cooking chamber, however, is that the humidity of the cooking chamber is significantly changed. This can possibly lead to a deterioration of the cooking result.

Eine andere Methode zum Abkühlen des Garraumes zeigt die DE 102008012681 A1 . Hier wird unter Verwendung eines bestimmten Ventils das Heißluftgebläse des Garraumes entweder zum Umwälzen der Luft im Garraum oder zum Ansaugen von Frischluft benutzt. Dabei soll in der gleichen Leitung eine gegenläufige Strömung von einströmender Frischluft und ausströmender feuchter Garraumluft erzeugt werden. Nachteilig dabei ist allerdings, dass die Frischluft aus dem Unterdruckbereich hinter dem Heißluftgebläse angesaugt wird. Dadurch kann nur ein geringer Luftstrom zur Kühlung eingesetzt werden, wodurch lange Zeiträume zur Abkühlung erforderlich werden, in denen der Garprozess weiterläuft.Another method for cooling the cooking chamber shows the DE 102008012681 A1 , Here, using a specific valve, the hot air blower of the cooking chamber is used either for circulating the air in the oven or for the intake of fresh air. It should be generated in the same line an opposite flow of incoming fresh air and outflowing moist cooking chamber air. The disadvantage here, however, is that the fresh air is sucked in from the negative pressure area behind the hot air blower. As a result, only a small air flow can be used for cooling, whereby long periods are required for cooling, in which the cooking process continues.

Aus der WO 00/52392 A1 und aus der WO 2005/078352 A1 sind Gargeräte bekannt, bei denen die Garraumtür zum Ende eines Programms geöffnet wird. Bei der WO 2005/078352 A1 wird die Tür anschließend nach Unterschreiten eines physikalischen Schwellenwertes wieder geschlossen.From the WO 00/52392 A1 and from the WO 2005/078352 A1 Cooking appliances are known in which the cooking chamber door is opened at the end of a program. In the WO 2005/078352 A1 the door is then closed again after falling below a physical threshold value.

Es ist daher die Aufgabe der vorliegenden Erfindung, ein Verfahren zum Betreiben eines Gargeräts zur Verfügung zu stellen, das eine effektive Abkühlung des Garraumes auch bei gut isolierten Geräten zuverlässig und zügig erlaubt.It is therefore an object of the present invention to provide a method for operating a cooking appliance, which allows effective and rapid cooling of the cooking chamber even with well insulated devices.

Diese Aufgabe wird gelöst durch ein Verfahren zum Betreiben eines Gargerätes mit den Merkmalen des Anspruchs 1.This object is achieved by a method for operating a cooking appliance having the features of claim 1.

Das erfindungsgemäße Verfahren eignet sich zum Betreiben eines Gargerätes mit wenigstens einem thermisch heizbaren Garraum. Dabei ist wenigstens eine den Garraum verschließende Tür vorgesehen, die den wenigstens einen Garraum verschließt. Wenigstens eine Öffnungseinrichtung ist für die wenigstens eine Garraumtür vorgesehen, mittels welcher die Garraumtür automatisch wenigstens einen Spalt geöffnet werden kann, um eine schnelle Abkühlung des Garraumes zu unterstützen.The inventive method is suitable for operating a cooking appliance with at least one thermally heated cooking chamber. In this case, at least one door closes the cooking chamber is provided, which closes the at least one cooking chamber. At least one Opening device is provided for the at least one cooking chamber door, by means of which the cooking chamber door automatically at least one gap can be opened to support a rapid cooling of the cooking chamber.

Um das automatische Öffnen der Tür auch effektiv nutzen zu können, ist eine Steuereinrichtung vorgesehen, die mit der Öffnungseinrichtung in Verbindung steht. Dadurch kann die Funktion der Schnellabkühlung des Garraumes auch leicht in bestehende Betriebsprofile integriert oder mit verschiedenen Funktionen verknüpft werden. Das Öffnen der Tür ist während eines Garprofils vorgesehen. Insbesondere beim Garen von großen Fleischstücken, wie zum Beispiel einem Braten, könnte das Lebensmittel bei sehr hohen Temperaturen direkt im Backofen angebraten werden, bis eine Kruste mit der gewünschten Bräunung entstanden ist. Anschließend muss der Garraum möglichst schnell auf eine Niedergartemperatur abgekühlt werden. Dies wird über ein automatisches Öffnen der Tür effektiv erreicht. Dabei auch vorgesehen, dass die Tür von der Öffnungseinrichtung wieder geschlossen werden kann. Dadurch ist es möglich, den Garraum während eines Garprozesses zur Abkühlung kurzzeitig zu öffnen und anschließend wieder zu verschließen. Dies ist insbesondere dann sinnvoll, wenn ein Garprozess mit sehr hoher Hitze begonnen wird, dann auf einer Niedergartemperatur weiter gegart werden soll.In order to use the automatic opening of the door effectively, a control device is provided, which communicates with the opening device in connection. As a result, the function of the rapid cooling of the cooking chamber can also be easily integrated into existing operating profiles or linked to various functions. The opening of the door is provided during a cooking profile. In particular, when cooking large pieces of meat, such as a roast, the food could be seared at very high temperatures directly in the oven until a crust with the desired browning is formed. Subsequently, the cooking chamber must be cooled as quickly as possible to a low temperature. This is effectively achieved by automatically opening the door. It also provided that the door of the opening device can be closed again. This makes it possible to briefly open the cooking chamber during a cooking process for cooling and then close it again. This is particularly useful when a cooking process is started with very high heat, then should be cooked at a low temperature.

Ein derart ausgestaltetes Verfahren ist sehr vorteilhaft. Ein erheblicher Vorteil ist, dass die Tür des Garraumes automatisch mittels der Öffnungseinrichtung wenigstens einen Spalt weit geöffnet werden kann. Durch das automatische Öffnen der Garraumtür wird ein erheblicher Komfortgewinn für einen Benutzer erreicht, der ein fertig gegartes Lebensmittel nach Abschuss eines Garvorganges nicht mehr direkt aus dem Garraum entnehmen muss.Such a configured method is very advantageous. A considerable advantage is that the door of the cooking chamber can be opened automatically by means of the opening device at least one gap. The automatic opening of the cooking chamber a significant gain in convenience for a user is achieved, which does not have to remove a finished cooked food after launching a cooking process directly from the oven.

Gargeräte sind mittlerweile so gut isoliert, dass ein Lebensmittel auch bei vollständigem Abschalten der Heizquellen weitergaren würde. Dadurch könnte das Lebensmittel im schlimmsten Fall ungenießbar werden. Durch Automatikprogramme zum Garen von Lebensmitteln in Kombination mit dem erfindungsgemäßen Verfahren kann es beispielsweise möglich werden, einen Garvorgang, wie zum Beispiel das Backen eines Kuchens, zu starten, ohne in Reichweite des Gargerätes verbleiben zu müssen, um den Kuchen nach Erreichen des gewünschten Bräunungsgrades aus dem Ofen zu entnehmen oder aber die Tür von Hand zu öffnen.Cooking appliances are now so well insulated that a food would continue to cook even with complete shutdown of the heating sources. This could make the food inedible at worst. By automatic programs for cooking food in combination with the method according to the invention, it may be possible, for example, to start a cooking process, such as baking a cake, without having to remain within reach of the cooking appliance to the cake after reaching the desired degree of browning to remove the oven or to open the door by hand.

Besonders bevorzugt ist es, dass die Garraumtür erst nach einer vorbestimmten Zeit oder ab einer vorbestimmten Temperatur automatisch geöffnet wird. Dadurch kann vermieden werden, dass zu heiße und/oder zu feuchte Luft aus dem Garraum stoßhaft austreten kann. Dadurch kann das Aufheizen von zum Beispiel der Bedienblende des Gargerätes und auch Kondensatbildung besser vermieden werden. Denkbar ist zudem, dass die Garraumtür zunächst nur einen Schritt weit geöffnet wird und erst nach einer vorbestimmten Zeit oder ab einer vorbestimmten Garraumtemperatur auf die zur Abkühlung vorgesehene Spaltbreite geöffnet wird. Besonders vorteilhaft, wird neben dem Öffnen der Garraumtür gleichzeitig das Heißluftgebläse oder das Gebläse außerhalb des Garraums das kalte Luft von außen in den Garraum bläst, betrieben. Alternativ können neben dem Öffnen der Garraumtür gleichzeitig das äußere Gebläse und das Heißluftgebläse betrieben werden.It is particularly preferred that the cooking chamber door is opened automatically only after a predetermined time or from a predetermined temperature. As a result, it can be avoided that excessively hot and / or excessively moist air can escape from the cooking chamber in an abrupt manner. Thereby The heating of, for example, the control panel of the cooking appliance and condensate formation can be better avoided. It is also conceivable that the cooking chamber door is initially only one step wide open and only after a predetermined time or from a predetermined cooking chamber temperature is opened to the provided for cooling gap width. Particularly advantageous, in addition to the opening of the cooking chamber door at the same time the hot air blower or the fan outside the cooking chamber blows the cold air from the outside into the oven, operated. Alternatively, in addition to the opening of the cooking chamber door simultaneously the external fan and the hot air blower can be operated.

Die Öffnungseinrichtung kann über viele Funktionsweisen verwirklicht werden. Besonders bevorzugt ist, dass die Öffnungseinrichtung motorisch, hydraulisch, pneumatisch und/oder magnetisch vorgesehen ist. Dabei kann die Tür zum Beispiel über das Verfahren einer Zahnstange geöffnet und auch wieder geschlossen werden. Auch das Öffnen mittels eines Druckzylinders ist sinnvoll. Dabei kann die Tür zum Beispiel durch ein Entlasten des Druckzylinders wieder geschlossen werden. Es kann auch eine Feder vorgesehen sein, die die Tür wieder in die geschlossene Position zurückzieht. Aber auch andere geeignete Mechanismen, wie zum Beispiel eine motorisierte Drehachse an der Tür, können zum Öffnen und Schließen der Garraumtür vorgesehen sein.The opening device can be realized by many functions. It is particularly preferred that the opening device is provided by motor, hydraulic, pneumatic and / or magnetic. The door can be opened, for example, via the method of a rack and closed again. The opening by means of a printing cylinder is useful. In this case, the door can be closed again, for example, by relieving the pressure cylinder. It may also be provided a spring, which pulls the door back to the closed position. But other suitable mechanisms, such as a motorized rotation axis on the door, can be provided for opening and closing the cooking chamber door.

Insbesondere nach einem Pyrolysevorgang kann es sinnvoll sein, eine gewisse Zeit abzuwarten, bevor die Garraumtür geöffnet wird. Dazu können insbesondere auch ermittelte Werte von einem oder mehreren Sensoren zur Messung z.B. der Garraumtemperatur oder der Luftfeuchtigkeit im Garraum berücksichtigt werden.In particular, after a pyrolysis process, it may be useful to wait a certain time before the oven door is opened. For this purpose, in particular also determined values of one or more sensors for measuring e.g. the cooking space temperature or the humidity in the cooking space are taken into account.

Weitere Vorteile und Merkmale der vorliegenden Erfindung ergeben sich aus dem Ausführungsbeispiel, welches im Folgenden mit Bezug auf die beiliegenden Figuren erläutert wird. Dabei zeigt:

Further advantages and features of the present invention will become apparent from the embodiment, which will be explained below with reference to the accompanying figures. Showing:
FIG. 1

FIG. 2
a schematic representation of a cooking appliance in a sectional view with an opening device for rapid cooling of the cooking chamber.

Figur 1 zeigt ein Gargerät 1, dass hier als Backofen 30 für den Einbau in einen Möbelkorpus ausgebildet ist. Der Backofen 30 umfasst ein Gehäuse 24, in dem ein mit einer Tür 4 verschließbarer Garraum 2 angeordnet ist, in dem Speisen unter Verwendung verschiedener Betriebsprofile zubereitet werden können. Unter anderem kann über eine hier nur schematisch dargestellte Bedienblende 23 zwischen unterschiedlichen Betriebsarten gewählt werden. Dabei können verschiedene Heizquellen 3 zum Zubereiten der Speisen verwendet werden. Zum Beispiel können ein Umluftbetrieb, Ober- und Unterhitze und eine Grillfunktion verwendet werden. Auch die Temperatur kann eingestellt werden. Die Bedienblende 23 kann als Touchpanel ausgeführt sein oder auch nicht näher dargestellte Bedienelemente umfassen. FIG. 1 shows a cooking appliance 1, that is designed here as oven 30 for installation in a furniture body. The oven 30 comprises a housing 24 in which a cooking chamber 2 which can be closed with a door 4 is arranged, in which food can be prepared using different operating profiles. Among other things, about one here only schematically shown control panel 23 can be selected between different modes. In this case, different heat sources 3 can be used to prepare the food. For example, a recirculating air mode, top and bottom heat, and a grill function can be used. The temperature can also be adjusted. The control panel 23 may be designed as a touch panel or include controls not shown in detail.

Durch immer weiter steigende Anforderungen bezüglich der Energieeffizienz von Haushaltsgeräten sind das Gargerät 1 und insbesondere der Garraum 2 sehr gut isoliert, wodurch der aufgeheizte Garraum 2 die eingebrachte Wärme selbst nach Ausschalten der Heizquelle 3 nur sehr langsam verliert. Das ist zwar ein großer Vorteil für die Energiebilanz eines Gargerätes 1, bringt aber in manchen Situationen auch Nachteile mit sich.Due to ever increasing requirements regarding the energy efficiency of household appliances, the cooking appliance 1 and in particular the cooking chamber 2 are very well insulated, whereby the heated cooking chamber 2 loses the introduced heat even after switching off the heat source 3 only very slowly. Although this is a great advantage for the energy balance of a cooking appliance 1, but also brings disadvantages in some situations.

Beispielsweise muss ein Benutzer ein Lebensmittel sofort oder beispielsweise bei Automatikprogrammen mit automatischer Erkennung des Fertigzeitpunktes des Lebensmittels, dieses aus dem Garraum entnehmen, sobald es fertig gegart ist, um ein Nachbräunen oder sogar Verbrennen des Lebensmittels zu verhindern. Optional muss die Garraumtür von Hand geöffnet werden und insbesondere ist die das Lebensmittel aufnehmende Gargutauflage zusätzlich noch mindestens so weit wie möglich herauszuschieben, um die heiße Luft aus dem Garraum zu entlassen. Insbesondere die Garraumwände müssen abgekühlt werden. Sie speichern viel mehr Wärme als die heiße Garraumluft.For example, a user must immediately, or for example in automated programs with automatic detection of the finish time of the food, remove a food from the cooking chamber once it has finished cooking in order to prevent re-tanning or even burning of the food. Optionally, the cooking chamber door must be opened by hand and, in particular, the food support accommodating the food item must additionally be pushed out at least as far as possible in order to release the hot air from the cooking space. In particular, the cooking chamber walls must be cooled. They store much more heat than the hot cooking air.

Auch wenn zunächst eine sehr hohe Temperatur zur Erhitzung der Garraumluft und der Garraumwände verwendet wird, die anschließend zügig verringert werden muss, ist bisher das Eingreifen des Benutzers erforderlich. Dies ist für einen Benutzer nicht sehr praktisch. Außerdem kann zum Beispiel das Öffnen der Tür am Ende eines Garprozesses auch leicht vergessen werden. Gerade bei der Verwendung von Automatikprogrammen wäre es für einen Benutzer sehr komfortabel, wenn er nach dem Anstellen des Programms nicht mehr in den Garprozess eingreifen müsste.Even if initially a very high temperature is used to heat the oven air and the cooking chamber walls, which then has to be reduced quickly, so far the intervention of the user is required. This is not very practical for a user. In addition, for example, the opening of the door at the end of a cooking process can also be easily forgotten. Especially with the use of automatic programs, it would be very convenient for a user if he no longer had to intervene in the cooking process after starting the program.

Auch beim Pyrolysebetrieb können Komforteinbußen für den Benutzer entstehen. Ist das Gerät mit dem Pyrolysebetrieb fertig, dauert es unter Umständen sehr lange, bis das Gargerät wieder betriebsbereit ist. Aus Sicherheitsgründen kann man die Tür nämlich erst ab einer gewissen Temperatur wieder öffnen, was beim Abkühlen von bis zu 500°C lange Zeit in Anspruch nehmen kann.Also in the pyrolysis operation can cause loss of comfort for the user. If the device is finished with the pyrolysis operation, it may take a very long time until the cooking appliance is ready for use again. For safety reasons, the door can only be opened again after a certain temperature, which can take a long time to cool down up to 500 ° C.

Um eine schnelle Abkühlung des Gargerätes 1 zu ermöglichen, die den Garraum 2 einerseits schnell, andererseits aber auch zuverlässig abkühlt, ist in Figur 2 eine Öffnungseinrichtung 10 vorgesehen, die dazu geeignet und ausgebildet ist, die Garraumtür 4 wenigstens einen Spalt 7 weit zu öffnen. Ein Eingreifen des Benutzers ist dann nicht mehr von Nöten, da die Öffnungseinrichtung 10 die Garraumtür 4 automatisch öffnen kann.In order to allow rapid cooling of the cooking appliance 1, which cools the cooking chamber 2 on the one hand fast, but on the other hand also reliable, is in FIG. 2 an opening device 10 is provided, which is suitable and designed, the cooking chamber door 4 at least one gap. 7 wide open. An intervention of the user is then no longer necessary, since the opening device 10, the cooking chamber door 4 can open automatically.

Die Öffnungseinrichtung 10 kann verschiedenste Ausgestaltungen aufweisen. Zum Beispiel kann die Öffnungseinrichtung 10 über einen Motor betrieben werden, der zum Beispiel eine Stange verschiebt und somit die Tür 4 einen Spalt 7 weit aufdrückt. Auch ein hydraulischer, pneumatischer und/oder magnetischer Mechanismus ist für die Ausbildung der Öffnungseinrichtung 10 vorteilhaft.The opening device 10 can have a wide variety of configurations. For example, the opening device 10 may be operated by a motor which, for example, displaces a rod and thus urges the door 4 a gap 7 far. Also, a hydraulic, pneumatic and / or magnetic mechanism is advantageous for the formation of the opening device 10.

Auch andere geeignete Mechanismen, wie zum Beispiel eine motorisierte Drehachse an der Tür, können zum Öffnen und Schließen der Garraumtür vorgesehen sein. Bei jeder Art der Öffnungseinrichtung 10 ist dabei auch bevorzugt, dass die Öffnungseinrichtung aus designtechnischen Gründen möglichst unauffällig angeordnet ist. Dazu können Öffnungseinrichtungen 10 wie zum Beispiel Zahnstangen oder Druckzylinder in den Holmen des Gargerätgehäuses 24 angeordnet sein. Dadurch wären die Öffnungseinrichtungen 10 im Wesentlichen versteckt untergebracht.Other suitable mechanisms, such as a motorized rotation axis on the door, may be provided for opening and closing the cooking chamber door. In any type of opening device 10 is also preferred that the opening device is arranged as inconspicuous for design reasons. For this purpose, opening devices 10 such as toothed racks or pressure cylinders can be arranged in the bars of the cooking appliance housing 24. As a result, the opening devices 10 would be housed substantially hidden.

In dem in Figur 2 dargestellten Ausführungsbeispiel erfolgt die Öffnung über einen steuerbaren Druckzylinder 26, der mittels einer Stange 27 die Tür 4 ein Stück weit öffnet. Dabei können verschiedene Öffnungsweiten 7 von der Öffnungseinrichtung 10 eingestellt werden. Eine besonders bevorzugte Öffnungsweite 7 liegt dabei zwischen 0,5 cm und 5 cm, wobei in Figur 2 ein Spalt 7 von 1,9 cm eingestellt ist. Auch größere und kleinere Öffnungsweiten 7 können vorteilhaft sein.In the in FIG. 2 illustrated embodiment, the opening via a controllable pressure cylinder 26 which opens by means of a rod 27, the door 4 a bit wide. In this case, different opening widths 7 can be adjusted by the opening device 10. A particularly preferred opening width 7 is between 0.5 cm and 5 cm, wherein in FIG. 2 a gap 7 of 1.9 cm is set. Even larger and smaller opening widths 7 may be advantageous.

Durch die so leicht geöffnete Tür 4 kann dann die heiße Luft 8 schnell und effektiv aus dem Garraum 2 entweichen, wodurch eine Abkühlung des Garraumes 2 stattfindet. Wenn die erwünschte Temperatur erreicht ist, kann die Stange 27 wieder zurück in den Zylinder 26 verfahren, wodurch die Tür 4 wieder verschlossen wird. Die nötige Kraft zum Schließen der Tür 4 kann entweder von der Tür 4 selbst kommen, es ist allerdings auch denkbar, dass eine hier nicht näher gezeigte Zugeinrichtung, wie zum Beispiel eine Feder vorgesehen ist, die die Tür 4 wieder an die Garraumöffnung 25 heranzieht.Through the door 4, which is so easily opened, the hot air 8 can escape quickly and effectively from the cooking chamber 2, as a result of which a cooling of the cooking chamber 2 takes place. When the desired temperature is reached, the rod 27 can again move back into the cylinder 26, whereby the door 4 is closed again. The force required to close the door 4 can come either from the door 4 itself, but it is also conceivable that a pulling device, not shown here, such as a spring is provided, which pulls the door 4 back to the cooking chamber 25.

Um verschiedene Öffnungsweiten 7 der Öffnungseinrichtung 10 einstellen zu können, ist in dem hier gezeigten Ausführungsbeispiel eine Steuerungseinrichtung 5 vorgesehen. Diese steuert das automatische Öffnen der Tür 4 und kann das automatische Öffnen der Tür 4 auch in verschiedene Betriebsprofile integrieren.In order to be able to set different opening widths 7 of the opening device 10, a control device 5 is provided in the exemplary embodiment shown here. This controls the automatic opening of the door 4 and can integrate the automatic opening of the door 4 in various operating profiles.

Auch das manuelle Schnellabkühlen des Garraumes 2 ist möglich, da eine Betätigungseinrichtung 6 vorgesehen ist, die die Öffnungseinrichtung 10 auslösen kann. Dies kann entweder direkt erfolgen, oder aber über die Steuerungseinrichtung 5.The manual rapid cooling of the cooking chamber 2 is possible because an actuator 6 is provided which can trigger the opening device 10. This can be done either directly or via the control device 5.

Es können auch weitere Öffnungen 21 an dem Garraum vorgesehen sein, über die heiße Luft 8 aus dem Garraum 2 entweichen kann. Solch eine Öffnung 21 ist dann mit einer Verschlusseinrichtung 22 versehen, mittels welcher ein automatisches Öffnen und Verschließen der Öffnung 21 erreicht werden kann. Eine vorteilhafte Anordnung einer zusätzlichen Öffnung 21 wäre zum Beispiel der seitliche und/oder hintere Bereich des Garraumes 2.It can also be provided on the cooking chamber 21 further openings, can escape via the hot air 8 from the cooking chamber 2. Such an opening 21 is then provided with a closure device 22, by means of which an automatic opening and closing of the opening 21 can be achieved. An advantageous arrangement of an additional opening 21 would be, for example, the lateral and / or rear region of the cooking chamber 2.

Weiterhin ist in dem in Figur 2 gezeigten Gargerät 1 wenigstens ein Sensor 11 vorgesehen, der zum Beispiel die Lage der Tür 4, die Temperatur des Garraumes 2 und andere Parameter bestimmen kann. Unter Berücksichtigung der von dem Sensor 11 ermittelten Werte, kann die Steuerungseinrichtung 5 zum Beispiel auch das Öffnen der Tür 4 unterdrücken oder aber schrittweise erfolgen lassen, wenn beispielsweise die Temperatur im Garraum 2 über einem kritischen Wert liegt. Dann würde die Tür 4 zunächst einen kleinen Spalt 7 geöffnet, so dass das stoßartige Austreten von zu heißem Wrasen vermieden wird. Nach einer ersten Abkühlung kann die Tür 4 dann entweder direkt bis auf die gewünschte Öffnungsweite 7 oder aber auch nach und nach weiter geöffnet werden, um den Garraum 2 möglichst schnell abzukühlen.Furthermore, in the in FIG. 2 shown cooking appliance 1 at least one sensor 11 is provided, which can determine, for example, the position of the door 4, the temperature of the cooking chamber 2 and other parameters. Taking into account the values determined by the sensor 11, the control device 5 can also suppress, for example, the opening of the door 4 or else it can be carried out stepwise if, for example, the temperature in the cooking chamber 2 is above a critical value. Then the door 4 would first open a small gap 7, so that the jerky escape of too hot vapor is avoided. After a first cooling, the door 4 can then be opened either directly to the desired opening width 7 or even gradually to cool the cooking chamber 2 as quickly as possible.

Um den Garraum 2 noch besser abzukühlen, kann zum Beispiel das Heißluftgebläse 31 oder ein anderer Lüfter des Gargerätes 1 das Abkühlen unterstützen. Besonders effektiv kann der Garraum 2 abgekühlt werden, wenn außerhalb des Garraumes 2 ein Gebläse 20 angeordnet ist, das dazu geeignet und ausgerichtet ist, kalte Frischluft 9 in den Garraum 20 zu leiten. Die kalte Luft 9 kühlt den Garraum 2 einerseits effektiv ab, andererseits drückt die einströmende Luft 9 die heiße Luft 8 aus dem Garraum, wodurch die Abkühlung des Garraumes 2 zügig erfolgen kann.To cool the cooking chamber 2 even better, for example, the hot air blower 31 or another fan of the cooking appliance 1 can support the cooling. Particularly effective, the cooking chamber 2 can be cooled when outside the cooking chamber 2, a fan 20 is arranged, which is suitable and oriented to direct cold fresh air 9 into the cooking chamber 20. The cold air 9 cools the cooking chamber 2 on the one hand effectively, on the other hand, the incoming air 9 presses the hot air 8 from the cooking chamber, whereby the cooling of the cooking chamber 2 can be done quickly.

In dem hier gezeigten Ausführungsbeispiel ist das Gebläse 20 als Radialgebläse 12 ausgeführt, wodurch eine sehr effektive Luftförderung gewährleistet ist. Dabei sind insbesondere Luftmengen von mehr als 800 l/min bevorzugt. Das hier abgebildete Gebläse kann ca. 1000 l/min fördern. Auch größere oder kleinere Luftmengen können je nach Anwendung vorteilhaft sein.In the embodiment shown here, the blower 20 is designed as a radial fan 12, whereby a very effective air delivery is ensured. In particular, air quantities of more than 800 l / min are preferred. The blower shown here can deliver about 1000 l / min. Even larger or smaller amounts of air can be advantageous depending on the application.

In bevorzugten Ausgestaltungen ist das Gebläse 20 weiterhin als Gleichstromgebläse 14 ausgeführt, wodurch eine stufenlose Regelung möglich wird. Dabei kann die Steuerungseinrichtung 5 auch das Gebläse 20 steuern, wobei der Sensor 11 in dem hier gezeigten Beispiel auch den Zustand des Gebläses 20 ermitteln kann.In preferred embodiments, the fan 20 is further designed as a DC fan 14, whereby a stepless control is possible. In this case, the control device 5 can also control the fan 20, wherein the sensor 11 in the example shown here can also determine the state of the blower 20.

Das Gebläse 20 ist hier in einem Gehäuse 13 angeordnet und bläst die kalte Frischluft 9 über einen Verbindungskanal 19 in den Garraum. Damit der Luftstrom 17 nicht zu sehr abgeschwächt wird, ist bevorzugt höchstens ein Bogen 28 in dem Verbindungskanal 19 vorgesehen. Natürlich können auch mehrere Bögen vorgesehen sein, wodurch allerdings ein stärkeres Gebläse 20 notwendig werden könnte. Weiter ist darauf zu achten, den Verbindungskanal 19 nicht zu lang auszulegen. Um die Leistung des Gebläses 20 nicht zu beeinträchtigen ist hierbei eine Länge von unter 30 cm bevorzugt. Auch kürze oder längere Verbindungskanäle 19 sind denkbar, allerdings müsste eventuell das Gebläse 20 darauf abgestimmt werden, um eine ausreichende Kühlung zu gewährleisten.The blower 20 is arranged here in a housing 13 and blows the cold fresh air 9 via a connecting channel 19 in the cooking chamber. So that the air flow 17 is not attenuated too much, preferably at most one arc 28 is provided in the connection channel 19. Of course, several bends may be provided, which, however, a stronger fan 20 may be necessary. It should also be ensured that the connecting channel 19 is not laid out too long. In order not to impair the performance of the blower 20, a length of less than 30 cm is preferred. Also shorter or longer connecting channels 19 are conceivable, but possibly the fan 20 would have to be tuned to ensure adequate cooling.

Der Verbindungskanal weist in der in Figur 2 gezeigten Ausgestaltung auch eine Abdichtung 15 zwischen dem Gebläse 20 und dem Garraum 2 auf. Dabei ist eine Klappenvorrichtung 16 vorgesehen, die den Zugang 29 zum Garraum 2 verschließt. Die Klappenvorrichtung 16 ist so ausgeführt, dass diese durch zum Beispiel eine Feder in einer geschlossenen Position gehalten wird, wenn das Gebläse 20 nicht eingeschaltet ist. Der Luftstrom 17 des Gebläses 20 kann dann die Klappenvorrichtung 16 aufdrücken und so den Zugang 29 zum Garraum freigeben. Durch eine solche Klappenvorrichtung 16 wird verhindert, dass heiße Luft 8 aus dem Garraum 2 in den Bereich zwischen Garraum 2 und Gehäuse 24 entweichen kann.The connecting channel points in the in FIG. 2 embodiment shown, a seal 15 between the blower 20 and the cooking chamber 2. In this case, a flap device 16 is provided which closes the access 29 to the cooking chamber 2. The flapper device 16 is designed to be held in a closed position by, for example, a spring when the fan 20 is not turned on. The air flow 17 of the blower 20 can then press the flap device 16 and thus release the access 29 to the cooking chamber. Such a flap device 16 prevents hot air 8 from escaping from the cooking chamber 2 into the region between cooking chamber 2 and housing 24.

Das Gebläse 20 kann auch wahlweise, z.B. durch die Klappenvorrichtung 16 zur Kühlung elektrischer und elektronischer Bauteile oder zum Lufteinblasen in den Garraum, zu dessen Schnellabkühlung, oder zu beidem gleichzeitig verwendet werden.The fan 20 may also be optionally, e.g. be used by the flap device 16 for cooling electrical and electronic components or for air injection into the cooking chamber, for the rapid cooling, or both at the same time.

Das Gargerät 1 kann aber auch das externe Gebläse 20 zum Schnellabkühlen zusätzlich neben den sonst üblichen und erforderlichen hier nicht näher dargestellten Komponentenkühlgebläsen und Wrasenabsauggebläsen des Gargeräts 1 besitzen.The cooking appliance 1 can also have the external fan 20 for rapid cooling in addition to the usual and required component cooling fans and Wrasenabsauggebläsen the cooking appliance 1 not shown here.

In anderen Ausgestaltungen kann auch eine elektronisch gesteuerte Klappenvorrichtung vorgesehen sein. Diese könnte zum Beispiel mit der Steuerungseinrichtung in Verbindung stehen und je nach Bedarf geöffnet und geschlossen werden. Auch andere im Wesentlichen als Ventil wirkende Abdichtungen 15 sind denkbar.In other embodiments, an electronically controlled flap device may be provided. This could, for example, be associated with the controller and opened and closed as needed. Other seals 15 acting essentially as a valve are also conceivable.

Weiterhin weisen einige Gargeräte zum Beispiel im oberen Bereich der Garraummuffel eine Öffnung auf, über die die Entfeuchtung des Garraumes während eines Garprozesses erfolgt. Diese Öffnung kann dabei als Lochbild ausgeführt sein. Da das Gebläse 20 die Funktion der Garraumentfeuchtung ersetzen kann, ist es insbesondere auch möglich, das für die Garraumentfeuchtung vorgesehene Lochbild als Zugang 29 für den Luftstrom 17 zu verwenden. Eventuell muss das Lochbild in der Größe so angepasst werden, dass eine ausreichende Menge an kalter Frischluft 9 in den Garraum 2 gedrückt werden kann. In dem hier gezeigten Ausführungsbeispiel ist dabei ein Zugang von ca. 11 cm2 vorgesehen, was hier einem Lochbild von 5,2 cm Durchmesser mit ca. 28 Löchern entspricht. Es wird dadurch auch möglich, Gargeräte mit einem Gebläse 20 zum Abkühlen des Garraumes 2 nachzurüsten.Furthermore, some cooking appliances, for example, in the upper part of the Garraummuffel an opening through which the dehumidification of the cooking chamber takes place during a cooking process. This opening can be designed as a hole pattern. Since the fan 20 can replace the function of Garraumentfeuchtung, it is also possible in particular to use the space provided for Garraumentfeuchtung hole pattern as access 29 for the air flow 17. Maybe the hole pattern in the size must be adjusted so that a sufficient amount can be pressed to cold fresh air 9 in the cooking chamber 2. In the embodiment shown here, an access of about 11 cm 2 is provided, which corresponds here to a hole pattern of 5.2 cm diameter with about 28 holes. It is thereby also possible to retrofit cooking appliances with a fan 20 for cooling the cooking chamber 2.
