Abstract

Method for operating a controllable/regulatable cooker hood comprises measuring the current consumption of a hob using one or more transducers and processing the measurements using an evaluation unit so that as the current consumption increases, the suction power of the hood also increases, and vice versa. An Independent claim is also included for a device for operating a controllable/regulatable cooker hood. Preferred Features: As current consumption decreases, the evaluation unit induces a delayed reduction in suction power.

Description

Die Erfindung betrifft eine Dunstabzugshaube, die über Mittel zum Datenaustausch mit einer Sensorik verfügt, die Aktivitäten der Kochstellenbereichs-Anschaltung eines Elektrokochfeldes erfasst, so dass eine Steuerung/Regelung der Dunstabzugshaube auch in Abhängigkeit der registrierten Aktivitäten im Kochstellenbereich möglich ist.The invention relates to an extractor hood that has data exchange means with a sensor system, the activities of the hob area connection one Electric hob recorded, so that a control / regulation of the extractor hood also depending on the activities registered in the cooking area.

Derartige Steuer- bzw. Regelungseinrichtungen für Dunstabzugshauben sind bekannt. In der DE 199 07 149 A1, die noch weitere Quellen zum Stand der Technik benennt, wird eine Dunstabzugsvorrichtung beschrieben, die mit einer Dunsterfassungssensorik und zusätzlich mit einer eine anhaltende Aktivität der Kochstellenbereichs-Anschaltung mittelbar oder unmittelbar erfassenden Sensorik als Ansteuerorgane einer Steuerschaltung zur Inbetriebnahme der Dunstabzugsvorrichtung ausgestattet ist. Die Steuerschaltung ist derart funktionstechnisch konfiguriert, dass bei dem von der zusätzlichen Sensorik erfassten Kriterium einer Kochbereichs-Anschaltung für deren Dauer Steuerschaltungsbereiche für eine automatische Steuerung unter Einschluss der Dunsterfassungssensorik aktiviert sind.
Die zusätzliche Sensorik wird über eine Kleinststromversorgung im Stand-By-Betrieb in Dauereinsatz gehalten, so dass diese zusätzliche Sensorik jederzeit in der Lage ist, ein typisches Kriterium für die Kochbereichs-Anschaltung zu detektieren. Ein derartiges Kriterium ist nach der DE 199 07 149 A1 die Restwärmeanzeige, was aber voraussetzt, dass bereits eine relevante Heizleistung der Kochstelle zugeführt sein muss. Für zweckmäßiger wird es gehalten, die Inbetriebnahme der Kochstellensteuerung selbst zu detektieren, d. h. beispielsweise auf die Betätigung eines Hauptschalters oder sonstiger Eingabeorgane zu reagieren.Such control devices for extractor hoods are known. DE 199 07 149 A1, which also names other sources of prior art, describes an extractor device which, with a vapor detection sensor system and additionally with a sensor system that detects a continuing activity of the hotplate area connection directly or indirectly, as control elements of a control circuit for starting up the Extractor hood is equipped. The control circuit is functionally configured in such a way that when the criterion of a cooking area connection is detected by the additional sensor system, control circuit areas are activated for automatic control including the vapor detection sensor system for its duration.
The additional sensor system is kept in continuous use by means of a miniature power supply in stand-by mode, so that this additional sensor system is able to detect a typical criterion for the connection to the cooking area at any time. According to DE 199 07 149 A1, such a criterion is the residual heat indicator, which, however, presupposes that a relevant heating output must already be supplied to the hotplate. It is considered more expedient to detect the commissioning of the hotplate control itself, that is to say, for example, to react to the actuation of a main switch or other input devices.

Ein Nachteil dieser Lösung besteht darin, dass zusätzlich eine Dunsterfassungssensorik eingesetzt wird mit dem bekannten Mangel, dass bei einer wie auch immer gearteten Wrasenerkennung Geruchsstoffe nicht erkannt werden. Das ist zum Beispiel beim Anbraten der Fall. Ein weiterer Nachteil besteht darin, dass für die Sensorik eine Kleinststromversorgung im Stand-By-Betrieb notwendig ist. A disadvantage of this solution is that it also has a fog detection sensor system is used with the well-known deficiency that with any kind Vapor detection Odorants cannot be detected. That is for example with Sear the case. Another disadvantage is that for the sensors a Small power supply in stand-by mode is necessary.

Aufgabe der Erfindung ist es, eine Steuer/Regeleinrichtung für eine Dunstabzugshaube zu schaffen, die nur auf Aktivitäten der Kochstellen-Anschaltung eines Elektrokochfeldes basiert.The object of the invention is to provide a control device for an extractor hood create that only on activities of the hob connection of an electric hob based.

Gelöst wird diese Aufgabe mit den Merkmalen des Anspruchs 1, vorteilhafte Ausgestaltungen sind Gegenstand der Unteransprüche.This object is achieved with the features of claim 1, advantageous Refinements are the subject of the dependent claims.

Erfindungsgemäß ist zum Betrieb einer steuer- bzw. regelbaren Dunstabzugshaube, bei dem Aktivitäten der Kochstellenbereichs-Anschaltung detektiert und als Signale zum Steuern/Regeln insbesondere der Absaugleistung der Dunstabzugshaube eingesetzt werden, vorgesehen, dass die Stromaufnahme des Kochfeldes mit einem oder mehreren Messwertaufnehmern gemessen wird, und die Messwerte durch eine Auswerteeinheit verarbeitet werden, derart, dass mit steigender Stromaufnahme die Absaugleistung der Dunstabzugshaube erhöht wird und umgekehrt.
Weiterhin ist in einer vorteilhaften Ausgestaltung vorgesehen, dass bei sinkender Stromaufnahme die Auswerteeinheit eine verzögerte Reduzierung der Absaugleistung bewirkt.According to the invention, in order to operate a controllable extractor hood, in which activities of the cooking zone area connection are detected and used as signals for controlling / regulating, in particular, the suction power of the extractor hood, it is provided that the current consumption of the hob is measured with one or more measurement sensors, and the measured values are processed by an evaluation unit in such a way that the suction power of the extractor hood is increased as the current consumption increases, and vice versa.
Furthermore, it is provided in an advantageous embodiment that when the current consumption drops, the evaluation unit brings about a delayed reduction in the suction power.

Die Stromaufnahme des Kochfeldes ist ein Maß für die Stärke, mit der gekocht wird. Wird etwas angebraten oder offen gekocht, so sind die einzelnen Kochplatten auf hohe Stufen eingestellt. Damit fließt ein großer Strom. Die Stromstärke liegt im Amperebereich und ist ein leicht mess- und auswertbarer Parameter.The hob's power consumption is a measure of the strength with which it is cooked. Becomes slightly fried or cooked open, the individual hot plates are on high levels set. A large current flows with it. The current is in the amp range and is an easily measurable and evaluable parameter.

Die Stromaufnahme des Kochfeldes wird bevorzugt mit einem induktiven Messfühler gemessen. Dabei werden die Messwertaufnehmer an den einzelnen Adern des Netzkabels des Kochfeldes angeordnet oder ein Messwertaufnehmer wird um das gesamte Netzkabel gelegt.
Natürlich kann die Stromstärke auch mit einem anderen konventionellen Strommesser erfasst werden und daraus ein geeignetes Signal generiert werden.The power consumption of the hob is preferably measured using an inductive sensor. The transducers are arranged on the individual wires of the cooktop's power cord or a transducer is placed around the entire power cord.
Of course, the current strength can also be recorded with another conventional ammeter and a suitable signal can be generated from it.
