Description

Die Erfindung betrifft eine Sicherheitssteuersystem zum Steuern von Abluftfördergeräten gemäß dem Oberbegriff des Schutzanspruches 1.The invention relates to a security control system for controlling exhaust air conveyors according to the preamble protection claim 1.

Bei gleichzeitigem Betrieb von raumluftabhängigen Feuerstätten, z.B. Gasthermen, Holz- oder Kohleofen etc., und von Abluftfördergeräten, z.B. Dunstabzugshauben, besteht das Problem, dass durch das Abluftfördergerät im Raum ein Unterdruck erzeugt wird, durch den schädliche Gase, insbesondere Kohlenmonoxid, aus der Feuerstätte entzogen und in den Raum geleitet werden können. Ein Druckausgleich im Raum darf dann nur über das Nachströmen von Frischluft aus dem Außenbereich erfolgen und nicht über die Feuerstätte.With simultaneous operation of indoor air-dependent fireplaces, e.g. Gas heaters, wood or coal stoves etc., and from exhaust air conveyors, e.g. Range hoods, there is the problem that the exhaust air conveyor creates a negative pressure in the room is, by the harmful Gases, especially carbon monoxide, are withdrawn from the fireplace and can be directed into the room. A pressure equalization in the room can then only be done by the inflow of Fresh air from outside done and not over the fireplace.

Hiervon ausgehend liegt der Erfindung die Aufgabe zugrunde, ein Sicherheitssteuersystem zum Steuern von Abluftfördergeräten zu schaffen, das möglichst einfach aufgebaut ist und den Betrieb des Abluftfördergerätes nur dann ermöglicht, wenn die Luft keine gefährliche Kohlenmonoxid konzentration aufweist.The invention is based on this based on the task of a security control system for controlling To create exhaust air conveyors that if possible is simply constructed and the operation of the exhaust air conveyor only then allows if the air is not dangerous Has carbon monoxide concentration.

Diese Aufgabe wird erfindungsgemäß durch die Merkmale des Anspruches 1 gelöst. Vorteilhafte Ausführungsformen der Erfindung sind den weiteren Ansprüchen beschrieben.This object is achieved by the Features of claim 1 solved. Advantageous embodiments the invention are described in the further claims.

Das erfindungsgemäße Sicherheitssteuerungssystem ist gekennzeichnet durchThe safety control system according to the invention is characterized by

  • – einen Kohlenmonoxid detektierenden Gasdetektor,- one Carbon monoxide detecting gas detector,
  • – eine mit dem Gasdetektor verbundene Steuerelektronik mit einer Logikschaltung zum Auswerten eines vom Gasdetektor in Abhängigkeit des Kohlenmonoxidsgehalts der Luft abgegebenen Zustandssignals, und- one control electronics connected to the gas detector with a logic circuit for evaluating one from the gas detector depending on the carbon monoxide content the air signal emitted, and
  • – ein mit der Stromzuführung des Abluftfördergerätes in Wirkverbindung stehendes und von der Logikschaltung angesteuertes Relais zum Öffnen und Schließen der Stromzuführung des Abluftfördergerätes in Abhängigkeit des Kohlenmonoxidgehaltes der Luft.- on with the power supply of the exhaust air conveyor in operative connection standing relay controlled by the logic circuit for opening and closing the power supply of the exhaust air conveyor depending of the carbon monoxide content in the air.

Durch den Einsatz des erfindungsgemäßen Sicherheitssteuerungssystems kann das Abluftfördergerät nur dann benutzt werden, wenn kein Kohlenmonoxid festgestellt wird.By using the safety control system according to the invention the exhaust air conveyor can only be used when no carbon monoxide is found.

Gemäß einer vorteilhaften Ausführungsform ist der Gasdetektor derart ausgebildet, dass dieser in das Abluftfördergerät einbaubar ist.According to an advantageous embodiment the gas detector is designed such that it can be installed in the exhaust air conveyor is.

Die Erfindung wird nachfolgend anhand der Zeichnungen beispielhaft näher erläutert. In diesen zeigen:The invention is described below the drawings, for example explained. In these show:

1: eine schematische Darstellung eines Abluftfördergerätes in der Form einer Dunstabzugshaube, und 1 : a schematic representation of an exhaust air conveyor in the form of an extractor hood, and

2: ein Blockdiagramm zur Darstellung der wesentlichen Einzelheiten des erfindungsgemäßen Sicherheitssteuerungssystems. 2 : a block diagram to show the essential details of the safety control system according to the invention.

Aus 1 ist ein Abluftfördergerät 2 in der Form einer Dunstabzugshaube dargestellt, wobei schematisch angedeutet ist, dass die Steuerelektronik 4 im Bereich der Dunstabzugshaube angeordnet sein kann.Out 1 is an exhaust air conveyor 2 Shown in the form of an extractor hood, schematically indicating that the control electronics 4 can be arranged in the area of the extractor hood.

Aus 2 ist ersichtlich, dass ein Gasdetektor 3 über ein Kabel 8 mit der Steuerelektronik 4 in Verbindung steht. Der Gasdetektor 3 leitet mittels des Kabels 8 ein von der Kohlenmonoxidkonzentration der Luft abhängiges Zustandsignal an die Steuerelektronik 4. Die Steuerelektronik 4 wertet das Zustandsignal durch eine Logikschaltung 5 aus. Die Logikschaltung 5 gibt ein Schaltsignal an ein Relais 6 ab, um die Stromzuführung des Abluftfördergerätes 2 zu öffnen oder zu schließen. Das Abluftfördergerät ist nur betreibbar, wenn kein Kohlenmonoxidgas detektiert worden ist.Out 2 it can be seen that a gas detector 3 over a cable 8th with the control electronics 4 communicates. The gas detector 3 conducts by means of the cable 8th a status signal dependent on the carbon monoxide concentration in the air to the control electronics 4 , The control electronics 4 evaluates the status signal through a logic circuit 5 out. The logic circuit 5 gives a switching signal to a relay 6 from the power supply to the exhaust air conveyor 2 to open or close. The exhaust air conveyor can only be operated if no carbon monoxide gas has been detected.

Die Stromversorgung 9 der Steuerelektronik 4 wird aus der Hausstromversorgung oder aus der Stromversorgung des Abluftfördergerätes 2 entnommen.The power supply 9 the control electronics 4 is from the house power supply or from the power supply of the exhaust air conveyor 2 taken.

Weiterhin ist die Steuerelektronik 4 mit einem Alarmsignalgeber 7 ausgestattet, mit dem die Zustandsinformation des Gasdetektors 3 akustisch und optisch angezeigt wird.Furthermore, the control electronics 4 with an alarm signal generator 7 equipped with the status information of the gas detector 3 is displayed acoustically and optically.
