Aus dem Artikel "Heiße Platten" in Elektromarkt Nr. 3, März 1996, Seiten 16 bis 22, ist die
Verwendung eines Katalysators zum Umwandeln von Gerüchen und Fettschwaden, welche
beim Backen und Braten entstehen, in reine, feuchte Luft bekannt. Dabei wird im Gegensatz

Insbesondere in der EP 0 772 514 B1 sind selbstreinigende Oberflächen beschrieben, die durch künstliche Implementierung einer mikroskopischen Oberflächenstruktur, wie sie für die Lotus-Blüte bekannt ist, in hydrophoben Polymeren oder haltbar hydrophobierten Materialien realisierbar sind.In particular, EP 0 772 514 B1 describes self-cleaning surfaces which through the artificial implementation of a microscopic surface structure, as used for the Lotus bloom is known in hydrophobic polymers or durable hydrophobic materials are realizable.
Aufgabe der gegenwärtigen Erfindung ist es, das gattungsgemäße Gargerät dahingehend weiterzuentwickeln, daß die Nachteile des Stands der Technik überwunden werden, insbesondere grober Dreck, Fettspritzer und/oder dergleichen aufgefangen werden kann bzw. können und nicht auf die Heizeinrichtung trifft bzw. treffen, so daß die Heizeinrichtung geschont wird. The object of the present invention is the generic cooking appliance to further develop the disadvantages of the prior art, in particular Coarse dirt, grease splashes and / or the like can be caught and does not hit the heater, so that the heater is protected becomes.
Diese Aufgabe wird erfindungsgemäß gelöst durch eine Aufprallfläche, die im wesentlichen konzentrisch um die Heizeinrichtung angeordnet ist, wobei die Heizeinrichtung zumindest teilweise im Strömungsschatten der Aufprallfläche angeordnet ist.This object is achieved according to the invention by an impact surface which essentially is arranged concentrically around the heating device, the heating device at least is partially arranged in the flow shadow of the impact surface.

Femer ist erfindungsgemäß vorgesehen, daß die Aufprallfläche im hinteren Bereich des Garraums in Ausblasrichtung angeordnet ist.It is also provided according to the invention that the impact surface in the rear area of the cooking space is arranged in the blow-out direction.
Erfindungsgemäß ist weiterhin vorgesehen, daß die Aufprallfläche in Form eines Abscheiderings zum Abscheiden von Feststoff- und/oder Flüssigkeitspartikeln aus einem Gasvolumen ausgebildet ist.According to the invention it is further provided that the impact surface in the form of a separating ring for separating solid and / or liquid particles from a gas volume is trained.
Bevorzugt ist, daß die Heizeinrichtung in Form von zumindest einem, vorzugsweise zwei, ringförmigen Heizkörpern ausgebildet ist.It is preferred that the heating device in the form of at least one, preferably two, annular radiators is formed.

Ferner kann erfindungsgemäß vorgesehen sein, daß der Katalysator Aluminiumoxid und/oder Platin umfaßt.It can further be provided according to the invention that the catalyst is aluminum oxide and / or Includes platinum.
Der Erfindung liegt somit die überraschende Erkenntnis zugrunde, daß durch die spezielle Anordnung der Aufprallfläche derart, daß die Heizeinrichtung zumindest teilweise im Strömungsschatten der Aufprallfläche angeordnet ist, diese Heizeinrichtung vor einer Abnutzung durch Ablagerung von Dreck, Fett und/oder dergleichen geschont werden kann, da die Aufprallfläche solchen Dreck, Fettspritzer und/oder dergleichen auffängt.

Zudem kann der Katalysator selbst derart ausgestaltet sein nach der Erfindung, daß dessen Oberflächenstruktur schmutzabweisend ist.In addition, the catalyst itself can be designed according to the invention that Surface structure is dirt-repellent.
Weitere Merkmale und Vorteile der Erfindung ergeben sich aus der nachfolgenden Beschreibung, in der ein Ausführungsbeispiel der Erfindung anhand von schematischen Zeichnungen im einzelnen erläutert ist. Dabei zeigt:
Figur 1- eine Teillängsschnittansicht des erfindungsgemäßen Gargeräts; und
Figur 2- eine Querschnittsansicht des erfindungsgemäßen Gargeräts von
Figur 1.

- a partial longitudinal sectional view of the cooking device according to the invention; and
- Figure 2
- 2 shows a cross-sectional view of the cooking appliance according to the invention from FIG. 1.
Wie den Figuren 1 und 2 zu entnehmen ist, umfaßt ein erfindungsgemäßes Gargerät 1 insbesondere
einen Garraum 2, der über ein Luftleitblech 3 von einem Gebläseraum 4 getrennt ist.
Dabei weist das Luftleitblech 3 zumindest eine nicht gezeigte Einlaß- und Auslaßöffnung zur
Luftzirkulation zwischen dem Garraum 2 und dem Gebläseraum 4 auf.As can be seen from FIGS. 1 and 2, a
Im Gebläseraum 4 sind ein Lüfterrad 10, zwei Heizkörper 11, 12, eine Vielzahl von an einem
Katalysatorgehäuse 13 angebrachten Katalysatorelementen 14 und eine Aufprallfläche zum
Abscheiden von Feststoff- und/oder Flüssigkeitspartikeln in Form eines Abscheiderings 15
angeordnet. Dabei sind konzentrisch zum Lüfterrad 10 ein innerer Heizkörper 11, konzentrisch
zum inneren Heizkörper 11 ein äußerer Heizkörper 12, konzentrisch zum äußeren Heizkörper
12 der Abscheidering 15 und konzentrisch zum Abscheidering 15 die Katalysatorelemente
14 angeordnet.In the
Werden, beispielsweise, im Garraum 2 Hähnchen gegart, so kommt es zu einer starken Geruchsbildung
und Erzeugung von Fettschwaden innerhalb des Garraums 2. Das Lüfterrad 10
sorgt dann dafür, daß Geruchspartikel und Fette aus dem Garraum 2 in den Gebläseraum 4
und dort auf die Katalysatorelemente 14 geleitet werden, um somit eine Umwandlung der
Geruchspartikel und der Fette in reine, feuchte Luft zu ermöglichen, die dann wieder dem
Garraum 2 zuführbar ist. Durch die spezielle Anordnung der Aufprallfläche des Abscheiderings
15 und der Heizeinrichtung 11, 12 im Strömungsschatten der Aufprallfläche ist Luft
sehr gezielt auf die Katalysatorelemente 14 richtbar, so daß insbesondere eine Verschmutzung
der Heizeinrichtung 11, 12 vermieden werden kann.If, for example, 2 chickens are cooked in the cooking space, there is a strong odor
and generation of fat vapors within the
Bei der Reinigung der Garraumatmosphäre mittels der Katalysatorelemente wird zudem
Energie freigesetzt, die beispielsweise zu einem weiteren, gezielten Aufheizen des Garraums
2 einsetzbar ist. Somit ermöglicht das erfindungsgemäße Gargerät 1, insbesondere Fette und
andere Kohlenwasserstoffe, die während eines Garvorgangs entstehen, unter Energiegewinn
zu entsorgen. Da der Energiegehalt tierischer Fette beispielsweise in der Größenordnung von
1 kWh pro 100 g liegt, läßt sich eine kostengünstige und energiesparende Luftreinigung mit
dem erfindungsgemäßen Aufbau erhalten, ohne daß insbesondere die Heizeinrichtung verschmutzt
wird.When cleaning the cooking cabinet atmosphere using the catalytic converter elements
