Abstract

The cooking stove has pyrolitic self-cleaning of the oven, together with a fume flue from the latter with after-burner. The flue (3) comprises parallel main (4) and auxiliary (5) sections, containing a controllable shutter and the after-burner (7,6). In normal use, the inlet from the oven (1) to the auxiliary section is shut off and while cleaning that to the main section is also shut off. ADVANTAGE - Uses catalytic after-burner only during cleaning.

Description

Die Erfindung betrifft einen Herd nach dem Oberbegriff des Patentanspruches 1.The invention relates to a stove according to the preamble of Claim 1.

Aus der DE-AS 23 29 024 ist ein Herd dieser Art bekannt, bei dem der katalytische Nachverbrenner unmittelbar im Wrasenabzug, der in der deckseitigen Bratraumwandung ausgebildet ist, angeordnet ist. Dies hat zur Folge, daß bei Normalbetrieb, welcher an sich der Regelfall ist, der beim Backen und Braten üblicherweise entstehende Wrasen zwangsweise über den Nachverbrenner abgeführt werden muß. Dies führt jedoch zu einer an sich unnötigen erheblichen Belastung der Küchenatmosphäre mit Verbrennungsgasen, deren nachteilige Folgen noch nicht überall voll erkannt sind.From DE-AS 23 29 024 a stove of this type is known, in which the catalytic afterburner directly in the fume hood, which in the is formed on the top-side roasting chamber wall. this has with the result that in normal operation, which is the normal case, the vapors that are usually produced during baking and roasting are forced over the afterburner must be removed. However, this leads to one yourself with unnecessarily significant pollution of the kitchen atmosphere Combustion gases, the adverse consequences of which are not yet fully everywhere are recognized.

Der Erfindung liegt die Aufgabe zugrunde, einen Herd der eingangs genannten Art so weiterzubilden, daß nur bei pyrolytischem Selbstreinigungsbetrieb der katalytische Nachverbrenner im Einsatz ist, ansonsten aber die beim Backen und Braten anfallenden Wrasen aus dem Bratraum ohne Veränderung ihrer Struktur abgeführt werden.The invention has for its object a stove of the beginning mentioned type so that only with pyrolytic Self-cleaning operation of the catalytic afterburner in use otherwise the vapors from baking and roasting Roasting chamber can be removed without changing their structure.

Diese Aufgabe wird gemäß der Erfindung gelöst durch die im kennzeichnenden Teil des Patentanspruches aufgeführten Merkmale. Vorteilhafte weitere Ausgestaltungen des Gegenstandes der Erfindung sind in den Unteransprüchen angegeben.This object is achieved according to the invention by the characteristic part of the claim listed features. Advantageous further developments of the subject matter of the invention are specified in the subclaims.

Durch die Erfindung wird erreicht, daß nur bei pyrolytischem Selbstreinigungsbetrieb des Bratraumes die bei diesem Vorgang entstehenden Gase über den Nachverbrenner abgeführt und einer Nachverbrennung unterzogen werden, jedoch die beim üblichen Back- und Bratbetrieb anfallenden Wrasen ohne thermische Nachbehandlung und damit ohne weitere Schadstoffentwicklung in die Küchenatmosphäre abgegeben bzw. abgeführt werden.The invention ensures that only with pyrolytic Self-cleaning operation of the roasting chamber during this process  resulting gases are discharged via the afterburner and one Subsequent incineration, however, in the usual baking and Vapors occurring during roasting without thermal aftertreatment and thus released into the kitchen atmosphere without further pollutant development or be dissipated.

Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt und wird anhand dieser nachfolgend näher beschrieben.An embodiment of the invention is shown in the drawing and is described in more detail below based on this.

Die Zeichnung zeigt in schematischer Darstellung eine den Back- und Bratraum (1) umschließende Ofenmuffel (2) für einen Herd, die deckseitig einen Wrasenabzug (3) aufweist. Der Wrasenabzug (3) ist zweckmäßig in einen Hauptkanalabzug (4) und in einen Nebenkanalabzug (5) aufgeteilt, wobei letzterer parallel zum Hauptkanalabzug (4) geschaltet ist. Im Nebenkanalabzug (5) ist ein katalytischer Nachverbrenner (6) und im Hauptkanalabzug (4) ist eine steuerbare Klappe (7) oder dergl. angeordnet. Hinter dieser Klappe (7) ist der Nebenkanalabzug (5) wieder mit dem Hauptkanalabzug (4) zusammengeführt. Die Klappe (7) ist mechanisch über einen die Betriebsart für den Bratraum (1) einstellenden manuell betätigbaren Wählschalter (8) in der Schalterblende (9) betätigbar. Das Betätigen bzw. Umschalten der Klappe (7) könnte auch auf elektrischem Wege mittels eines Relais oder dergl. durchgeführt werden. Bei Normalbetrieb des Bratraumes (1) ist der Wraseneingang zum Nebenkanalabzug (5) und bei Selbstreinigungsbetrieb ist der Wraseneingang zum Hauptkanalabzug (4) durch die Klappe (7) verschlossen. Die während des pyrolitischen Selbstreinigungsbetriebes über den Nachverbrenner (6) geführten Pyrolysegase gelangen nach Passieren des katalytischen Nachverbrenners (6) wieder in den Hauptkanalabzug (4) zurück, um von dort direkt oder über eine Küchendunstabzugshaube in die Küchenatmosphäre oder ins Freie, abgeführt zu werden.The drawing shows a schematic representation of a baking and the Bratraum (1) surrounding the oven muffle (2) for a cooker, the deck comprises a steam outlet side (3). The vapor extractor ( 3 ) is expediently divided into a main duct extractor ( 4 ) and a secondary duct extractor ( 5 ), the latter being connected in parallel to the main duct extractor ( 4 ). A catalytic afterburner ( 6 ) is arranged in the secondary duct extractor ( 5 ) and a controllable flap ( 7 ) or the like is arranged in the main duct extractor ( 4 ). Behind this flap ( 7 ), the secondary duct extractor ( 5 ) is brought together again with the main duct extractor ( 4 ). The flap ( 7 ) can be actuated mechanically via a manually operated selector switch ( 8 ) in the switch panel ( 9 ) which sets the operating mode for the roasting chamber ( 1 ). The actuation or switching of the flap ( 7 ) could also be carried out electrically by means of a relay or the like. During normal operation of the roasting chamber ( 1 ), the vapor inlet to the secondary duct extractor ( 5 ) and during self-cleaning operation, the vapor inlet to the main duct extractor ( 4 ) is closed by the flap ( 7 ). The pyrolysis gases passed through the afterburner ( 6 ) during pyrolytic self-cleaning operation return to the main duct extractor ( 4 ) after passing through the catalytic afterburner ( 6 ), in order to be discharged from there directly or via a kitchen extractor hood into the kitchen atmosphere or outside.
