Description
Die Erfindung betrifft ein Gargerät mit einer Mikrowellendichtung.The invention relates to a cooking appliance with a microwave seal.
Gargeräte, die eine Mikrowellenquelle zum Garen von Gargütern aufweisen sind hinreichend bekannt. Beim Betrieb der Mikrowellenquelle im Gargerät gilt es zu vermeiden, dass Mikrowellenstrahlung aus dem Gargerät austritt, um Strahlungsbelastungen der Benutzer des Gargerätes möglichst gering zu halten. Hierzu sind solche Gargeräte üblicherweise mit Mikrowellendichtungen versehen.Cooking appliances that have a microwave source for cooking food are well known. When operating the microwave source in the cooking appliance, it must be avoided that microwave radiation escapes from the cooking appliance in order to minimize the radiation exposure of the users of the cooking appliance. For this purpose, such cooking appliances are usually provided with microwave seals.
Insbesondere der Abdichtung der Beschickungsöffnung des Garraums gegenüber Mikrowellenstrahlung kommt große Bedeutung zu, weil die Beschickungsöffnung die größte Öffnung im Gehäuse des Gargerätes darstellt. Hierzu ist es bekannt, eine Mikrowellenfalle, beispielsweise eine λ/4-Falle, in der Garraumtür hinter einer Glasscheibe vorzusehen. Dadurch wird die Komplexität und Dicke der Garraumtüre jedoch vergrößert. Wird die Mikrowellendichtung am Gehäuse angeordnet, so ist sie nicht durch die Glasscheibe abgedeckt und verschmutzt rasch.In particular, the sealing of the loading opening of the cooking chamber with respect to microwave radiation is of great importance because the feed opening represents the largest opening in the housing of the cooking appliance. For this purpose, it is known to provide a microwave trap, for example a λ / 4 trap, in the cooking chamber door behind a glass pane. This, however, increases the complexity and thickness of the cooking chamber door. If the microwave seal is placed on the housing, it is not covered by the glass and dirty quickly.
Es ist Aufgabe der Erfindung, ein Gargerät mit einer Mikrowellendichtung bereitzustellen, die sowohl vor Verschmutzung geschützt ist als eine einfache und platzsparende Konstruktion der Garraumtüre ermöglicht.It is an object of the invention to provide a cooking appliance with a microwave seal, which is both protected from contamination as a simple and space-saving design of the cooking chamber door allows.
Die Aufgabe wird gelöst durch ein Gargerät mit einem Gehäuse, das einen Garraum aufweist, und einer Garraumtüre, die eine Beschickungsöffnung des Gehäuses verschließen kann, wobei ein Randbereich des Gehäuses sich an die Beschickungsöffnung anschließt, der von der Garraumtüre im geschlossenen Zustand vollständig abgedeckt wird, wobei der Randbereich des Gehäuses mit einer Mikrowellendichtung versehen ist und wobei am Randbereich eine Garraumdichtung zwischen der Mikrowellendichtung und dem Garraum angeordnet ist. Dabei wird unter dem Begriff "zwischen" auch verstanden, dass die Garraumdichtung zumindest teilweise in die Mikrowellendichtung hineinragt. Durch die Anordnung der Garraumdichtung am Gehäuse wird die Komplexität der Garraumtüre verringert. Gleichzeitig wird durch die Position der Garraumdichtung zwischen der Mikrowellendichtung und dem Garraum eine rasche Verschmutzung der Mikrowellendichtung verhindert, ohne dabei die Funktion der Mikrowellendichtung zu beeinträchtigen.The object is achieved by a cooking appliance with a housing, which has a cooking chamber, and a cooking chamber door, which can close a charging opening of the housing, wherein an edge region of the housing adjoins the charging opening, which is completely covered by the cooking chamber door in the closed state, wherein the edge region of the housing is provided with a microwave seal and wherein at the edge region a cooking chamber seal between the microwave seal and the cooking chamber is arranged. In this case, the term "between" also means that the cooking chamber seal projects at least partially into the microwave seal. The arrangement of the cooking chamber seal on the housing is the complexity the cooking chamber door reduced. At the same time a rapid contamination of the microwave seal is prevented by the position of the cooking chamber seal between the microwave seal and the cooking chamber, without affecting the function of the microwave seal.
Vorzugsweise umgibt die Mikrowellendichtung den Umfang der Beschickungsöffnung vollständig, so dass ein Austritt von Mikrowellenstrahlung durch die Beschickungsöffnung wirksam verhindert wird.Preferably, the microwave seal completely surrounds the circumference of the feed opening so that leakage of microwave radiation through the feed opening is effectively prevented.
Beispielsweise weist das Gehäuse einen Innenkasten und einen Außenkasten auf, wobei der Innenkasten den Garraum begrenzt und der Randbereich größtenteils am Außenkasten vorgesehen ist, sodass durch die Ausbildung der Mikrowellendichtung am Gehäuse der Garraum nicht verändert werden muss.For example, the housing has an inner box and an outer box, wherein the inner box limits the cooking space and the edge area is largely provided on the outer box, so that the cooking space does not have to be changed by the formation of the microwave seal on the housing.
In einer Ausführungsvariante ist die Mikrowellendichtung eine λ/4-Falle, wodurch eine einfache und bewährte Methode zur Verhinderung eines Austritts von Mikrowellenstrahlung gewählt ist.In one embodiment, the microwave seal is a λ / 4 trap, whereby a simple and proven method for preventing leakage of microwave radiation is selected.
In einer Ausgestaltung der Erfindung ist die Mikrowellendichtung als Nut im Randbereich, insbesondere einstückig mit dem Randbereich, ausgeführt, wodurch eine besonders einfache Ausgestaltung der Mikrowellendichtung ermöglicht wird. Die Nut kann dabei sowohl nur aus einem geraden Abschnitt bestehen als auch mehrere zueinander in einem Winkel angeordnete Abschnitte aufweisen oder spiralförmig sein.In one embodiment of the invention, the microwave seal is designed as a groove in the edge region, in particular in one piece with the edge region, whereby a particularly simple design of the microwave seal is made possible. The groove may consist of only a straight section and also have a plurality of mutually arranged at an angle sections or be spirally.
Vorzugsweise entspricht die Tiefe der Nut einem Viertel der Wellenlänge der im Gargerät verwendeten Mikrowellenstrahlung. Auf diese Weise wird eine λ/4-Falle realisiert.Preferably, the depth of the groove corresponds to a quarter of the wavelength of the microwave radiation used in the cooking appliance. In this way, a λ / 4 trap is realized.
In einer Ausführungsform der Erfindung ist die Garraumdichtung am Gehäuse befestigt, so dass die Komplexität der Garraumtüre weiter verringert wird.In one embodiment of the invention, the cooking chamber seal is attached to the housing, so that the complexity of the cooking chamber door is further reduced.
Die Garraumdichtung kann in der Nut angeordnet sein, wodurch der benötigte Bauraum für die Mikrowellendichtung und die Garraumdichtung verringert wird.The cooking chamber seal can be arranged in the groove, whereby the required space for the microwave seal and the cooking chamber seal is reduced.
Beispielsweise ist die Mikrowellendichtung auf der vom Garraum abgewandten Seite der Garraumdichtung angeordnet, wodurch eine rasche Verschmutzung der Mikrowellendichtung auf einfache Weise verhindert wird.For example, the microwave seal is arranged on the side facing away from the cooking chamber of the cooking chamber, whereby rapid contamination of the microwave seal is prevented in a simple manner.
In einer Ausführungsvariante wird die Nut durch eine für Mikrowellenstrahlung durchlässige Abdeckung verschlossen, wobei die Außenfläche der Abdeckung mit dem Randbereich eine Ebene bildet. Auf diese Weise wird eine Verschmutzung der Mikrowellendichtung verhindert und die Reinigung des Gargerätes durch die Ausbildung einer ebenen Fläche mit dem Randbereich vereinfacht.In one embodiment variant, the groove is closed by a cover permeable to microwave radiation, wherein the outer surface of the cover forms a plane with the edge region. In this way, contamination of the microwave seal is prevented and simplifies the cleaning of the cooking appliance by the formation of a flat surface with the edge region.
In einer Ausgestaltung der Erfindung kann an der Garraumtür eine weitere Mikrowellenfalle vorgesehen sein. Durch die weitere Mikrowellenfalle in der Garraumtür ist es möglich, den Austritt von Mikrowellenstrahlung aus dem Garraum weiter zu verringern, da die weitere Mikrowellenfalle eine andere Resonanzfrequenz als die Mikrowellendichtung des Gehäuses aufweisen kann. Auch ist es denkbar, dass aufgrund der Mikrowellendichtung im Gehäuse die Mikrowellenfalle in der Garraumtüre kleiner und einfacher ausgeführt sein kann, wodurch die Komplexität der Garraumtüre gering bleibt.In one embodiment of the invention, a further microwave trap can be provided on the cooking chamber door. The further microwave trap in the oven door, it is possible to further reduce the escape of microwave radiation from the cooking chamber, since the other microwave trap may have a different resonant frequency than the microwave seal of the housing. It is also conceivable that due to the microwave seal in the housing, the microwave trap in the cooking chamber door can be made smaller and simpler, whereby the complexity of the cooking chamber door remains low.
