Abstract
Description
Die vorliegende Erfindung betrifft eine Dunstabzugshaube gemäß dem Oberbegriff des Anspruchs 1 sowie ein Verfahren zum Betrieb einer Dunstabzugshaube nach dem Oberbegriff des Anspruchs 4.The The present invention relates to an extractor hood according to the preamble of claim 1 and a method for operating a cooker hood according to the preamble of claim 4.
Moderne Dunstabzugshauben über einem Kochherd oder Kochfeld sollen automatisch die Betriebsleistung ihres Lüfters in Abhängigkeit von Wrasen, Schlieren, Partikeln und dergleichen im Kochdunst regeln. Außerdem sollen sie möglichst den Verschmutzungsgrad ihres Filters erfassen, um dem Benutzer die Notwendigkeit eines Austausches des Filters anzuzeigen.modern Extractor hoods over a cooker or hob should automatically operate their fan dependent on of vapors, streaks, particles and the like in the cooking haze. Furthermore should they possibly detect the degree of pollution of their filter to the user Need to change the filter.

Regeln der Betriebsleistung des Lüfters einer Dunstabzugshaube
ist es aus dem Stand der Technik bekannt, dem Filter der Dunstabzugshaube einen
Ultraschall sensor vorzuschalten, mit dem Schlieren und dergleichen
im Luftstrom erfasst werden können.
Ein solcher Ultraschallsensor ist zum Beispiel in der
Der vorliegenden Erfindung liegt die Aufgabe zugrunde, eine Dunstabzugshaube und ein Verfahren zu ihrem Betrieb bereitzustellen, mit denen ein Verschmutzungsgrad des Filters erfasst werden können.Of the present invention is based on the object, an extractor hood and to provide a method of operation with which a degree of pollution of the filter can be detected.
Diese Aufgabe wird gelöst durch eine Dunstabzugshaube mit den Merkmalen des Anspruchs 1 bzw. durch ein Verfahren zum Betrieb einer Dunstabzugshaube mit den Merkmalen des Anspruchs 4. Vorteilhafte Ausgestaltungen und Weiterbildungen der Erfindung sind Gegenstand der abhängigen Ansprüche.These Task is solved by an extractor hood with the features of claim 1 or by a method of operating a cooker hood with the features of claim 4. Advantageous embodiments and further developments of Invention are the subject of the dependent claims.
Die Dunstabzugshaube enthält einen Lüfter zum Ansaugen eines Luftstroms, einen Filter zum Reinigen des Luftstroms, der stromauf des Lüfters angeordnet ist, und eine Steuervorrichtung zum Erfassen eines Verschmutzungsgrades des Filters. Erfindungsgemäß ist stromab des Lüfters ein Luftmassensensor angeordnet. Der Verschmutzungsgrad des Filters wird von der Steuereinrichtung auf der Basis einer Veränderung des von diesem Luftmassensensor erfassten Luftmassenstroms in Bezug zur Betriebsleistung des Lüfters bestimmt. Es wird hier ausgewertet, dass der Luftmassenstrom bei gleicher Betriebsleistung des Lüfters mit zunehmender Verschmutzung des Filters abnimmt. Der so erfasste Verschmutzungsgrad entspricht dabei sehr genau dem tatsächlichen Verschmutzungsgrad des Filters.The Extractor hood contains a fan for Aspiration of an air stream, a filter for purifying the air stream, located upstream of the fan is, and a control device for detecting a degree of contamination of the filter. According downstream is downstream of the fan arranged an air mass sensor. The degree of contamination of the filter is set by the controller based on a change the mass air flow detected by this air mass sensor with respect to the operating performance of the fan certainly. It is evaluated here that the air mass flow at same operating performance of the fan decreases with increasing contamination of the filter. The degree of contamination detected in this way corresponds very precisely to the actual degree of pollution of the filter.
Der Luftmassensensor ist vorzugsweise innerhalb eines Strömungsrohrs angeordnet und weist zum Beispiel zwei in Luftströmungsrichtung hintereinander angeordnete Heizwiderstände und wenigstens einen als Referenztemperatursensor dienenden Referenzwiderstand auf, wobei eine Differenz der elektrischen Widerstände der zwei Heizwiderstände ein Maß für den durch den Luftmassensensor strömenden Luftmassenstrom ist.Of the Air mass sensor is preferably within a flow tube arranged and has, for example, two in the air flow direction successively arranged heating resistors and at least one as Reference temperature sensor serving reference resistance, wherein a difference of the electrical resistances of the two heating resistors Measure of that through flowing the air mass sensor Air mass flow is.
