Abstract

The cooker hood also has a smoke and fire detector (4), or a temperature feeler, with adjustable reaction sensitivity, and an extinguishing device (7). This has a regulating valve (5), which is opened in case of fire, and closed, by the detector or the temperature feeler. The extinguishing material is carbon dioxide or similar, which does not leave a residue on the cooker hob. The hood has a control system, which switches off the blower (10) during the fire, and switches it on again afterwards, to extract the fumes.

Description

Die Erfindung bezieht sich auf eine Dunstabzugshaube mit einem Sauggebläse und mindestens einem Schwebstoff-Filter.The invention relates to an extractor hood with a suction fan and at least one particle filter.

Derartige Dunstabzugshauben arbeiten im Um- oder Abluftbetrieb. Die beim Kochen oder Braten entstehenden Dünste oder Schwaden werden durch die Dunstabzugshaube abgezogen, wobei die in der Abluft enthaltenen Geruchspartikel, Dämpfe oder Staub durch die Filtereinrichtung zurückgehalten werden. Zumeist enthalten die Dunstabzugshauben einen Fettfilter und nachfolgend einen Aktivkohlefilter, bevor sie das Gebläse passieren. Die in den Filtern zurückgehaltenen Verunreinigungen sind leicht brennbar. Eine Entzündung der Filter kann zum Beispiel dadurch entstehen, wenn überhitztes Fett unter den Filtern Feuer fängt und somit eine Entzündung der Filter herbeiführt. Durch die gleichzeitig vorhandene, hohe Sauerstoffzufuhr verwandelt sich die Dunstabzugshaube sehr schnell in eine Abart eines Flammenwerfers, der zur raschen Verbreitung des Brandes führt.Such extractor hoods work in recirculation or exhaust mode. The one while cooking or Vapors or steam generated by the cooker hood are removed from the cooker hood deducted, whereby the odor particles, vapors or dust contained in the exhaust air the filter device is retained. Mostly contain the extractor hoods a grease filter and then an activated carbon filter before they pass through the blower. The Contaminants retained in the filters are easily combustible. An infection For example, the filter can result if there is overheated fat under the filters Catches fire and thus ignites the filter. By the same time Existing, high oxygen supply quickly turns the extractor hood into a variety of a flamethrower that leads to the rapid spread of the fire.

Als Problem stellt sich bei Fettbränden jedoch nicht nur die Dunstabzugshaube dar, sondern auch das Umfeld um den Brandherd, welches es zu schützen gilt. So wird eine Vielzahl von Wohnungsbränden auf Fettbrände, welche sich von Kochstellen her ausbreiten, zurückgeführt.The problem with grease fires is not only the extractor hood, but also also the environment around the source of the fire, which needs to be protected. So a variety of Apartment fires on grease fires that spread from cooking areas recycled.

Weiterhin wurde erkannt, dass die Geruchsbelästigungen nach solchen Bränden unerträglich sind. Diese Gerüche lassen sich bei einem sofortigen Absaugen nach dem Brandfall sehr stark einschränken, da sie so an ihrer Ausbreitung gehindert werden. Aufgabe der Erfindung ist es, das Feuer auf der sich darunter befindenden Kochstelle zu löschen und somit eine Ausbreitung von Rauch und Flammen zu verhindern.It was also recognized that the odor nuisance after such fires are unbearable. These smells can be removed immediately after vacuuming Restrict fire in a very severe way, as this prevents them from spreading. The object of the invention is to fire on the hob below extinguish and thus prevent the spread of smoke and flames.

Dies geschieht gemäß der Erfindung dadurch, dass die Dunstabzugshaube einen Rauch- und Feuermelder oder Temperaturfühler aufweist, der die Stromzufuhr zum Sauggebläse und die Abluft über die Brandzeit unterbricht. Der Feuermelder kann als Schmelzsicherung oder als Temperaturfühler ausgebildet sein. An der Unterseite der Dunstabzugshaube sind Löschduschen angebracht, welche über ein Leitungssystem mit einem Kohlendioxid­ druckbehälter verbunden sind. [Es kann sich auch um andere Löschmittel handeln, welche druckfrei gelagert werden können.] Das Durchströmen des Leitungssystems wird durch ein eingebautes Ventil verhindert. Dieses Ventil wird im Brandfall von dem Rauch- und Feuermelder oder Temperaturfühler ausgelöst. [Das Ventil kann aber manuell betätigt werden.] Dann strömt das Kohlendioxid aus der Vorratsflasche am Steuerventil vorbei über das Leitungssystem zu den über der Kochstelle angeordneten Löschduschen. Das Feuer wird gelöscht.This happens according to the invention in that the extractor hood has a smoke and Fire detector or temperature sensor, which has the power supply to the suction fan and the Exhaust air interrupts during the fire period. The fire alarm can be used as a fuse or as Temperature sensors should be designed. At the bottom of the extractor hood are Extinguishing showers attached, which have a pipe system with a carbon dioxide pressure vessels are connected. [It can also be other extinguishing agents, which can be stored without pressure.] The flow through the pipe system is prevented by a built-in valve prevents. In the event of fire, this valve is activated by the smoke and Fire alarm or temperature sensor triggered. [The valve can be operated manually Then the carbon dioxide from the storage bottle flows past the control valve the pipe system to the fire showers arranged above the hotplate. The fire will deleted.

Nach dem Brand meldet der Temperaturfühler das Abfallen der Temperatur, was auf einen Löscherfolg schließen lässt. Dann wird die Stromverbindung zum Sauggebläse wieder hergestellt, damit nun die angefallenen Abgase abgesaugt werden können und das weitere Ausbreiten dieser verhindert wird. After the fire, the temperature sensor reports the drop in temperature, which indicates a Deletion success concludes. Then the power connection to the suction fan again manufactured so that the accrued exhaust gases can now be extracted and the rest Spreading of this is prevented.
