Description
Die Erfindung bezieht sich auf einen Brandwarnmelder gemäß dem Oberbegriff des Anspruchs 1.The invention relates to a fire alarm according to the preamble of
Rauchwarnmelder dienen allgemein der frühzeitigen Erfassung und akustischer Meldung von beginnenden Bränden in Gebäuden. Bei der Detektion eines Brandes wird ein dauerhafter, alarmierender Signalton vom Rauchmelder abgegeben, um anwesende Personen frühzeitig vor Bränden oder Brandrauch zu warnen.Smoke alarms are generally used for the early detection and acoustic reporting of incipient fires in buildings. When a fire is detected, a permanent, alarming signal is issued by the smoke alarm to warn people present at an early stage of fire or smoke.
Die Installation, Wartung und Funktionsweise solcher Rauchwarnmelder ist in der
Für die akustische Signalisierung wird üblicherweise ein Signalgeber und für die optische Signalanzeigen eine Leuchtdiode (LED) verwendet, wobei deren Leuchtsignale an die Gehäuseaußenseite geführt werden.For the acoustic signaling usually a signal generator and for the optical signal displays a light emitting diode (LED) is used, with their light signals are guided to the outside of the housing.
Die Platzierung, insbesondere der Leuchtdiode, führt dazu, dass dieses Bauteil negativen Einfluss auf das Strömungsverhalten innerhalb des Rauchwarnmelders bedingt, das sich aus erzeugten Verwirbelungen ergibt, die ein Eindringen des Brandrauch in die Rauchmesszelle verzögern und dadurch den Faktor bezüglich des Verhältnisses bestes-/schlechteste Auslöseverhalten negativ ansteigen lässt.The placement, in particular of the light-emitting diode, means that this component has a negative influence on the flow behavior within the smoke alarm, resulting from generated turbulences, which delay penetration of the smoke into the smoke cell and thereby the ratio best / worst Triggering behavior increases negatively.
Der Erfindung liegt die Aufgabe zugrunde, einen Rauchwarnmelder anzugeben, dessen Bauteile so platziert sind, dass diese das Strömungsverhalten der einströmenden Luft im Rauchwarnmelder verbessern und eine Reduzierung der aerodynamischen Turbulenzen durch optische Signalanzeigen bedingen.The invention has for its object to provide a smoke alarm, the components are placed so that they improve the flow behavior of the incoming air in the smoke detector and cause a reduction in aerodynamic turbulence by optical signal displays.
Diese Aufgabe wird durch einen Rauchwarnmelder mit einem Gehäuse, einem akustischem Signalgeber, einer Lichtquelle, einer Vielzahl von im Gehäuse angeordneten Einström- oder Eintrittsöffnungen, einer Rauchmesszelle zur Detektion von einströmender Luft auf Rauchpartikel und wenigstens einer im Gehäuseinnenraum angeordneten Vorrichtung zur Strömungsführung der einströmenden Raumluft mit den Merkmalen des Anspruches 1 gelöst. Vorteilhafte Ausgestaltungen der Erfindung ergeben sich aus der Beschreibung, den Figuren und den weiteren Ansprüchen.This object is achieved by a smoke detector with a housing, an acoustic signal transmitter, a light source, a plurality of inflow or inlet openings arranged in the housing, a smoke measuring cell for detecting incoming air to smoke particles and at least one arranged in the housing interior device for flow guidance of the incoming room air the features of
Erfindungsgemäß ist in die Vorrichtung zur Strömungsführung wenigstens ein Lichtleiter integriert, welcher das Licht der Lichtquelle, vorzugsweise einer Leuchtdiode oder einer Laserdiode, an die Gehäuseaußenseite führt, um die von den Lichtquellen ausgehenden aerodynamischen Verwirbelungen zu vermeiden und den Brandrauch ohne Verzögerungen von der Raucheintrittsöffnung in die Rauchmesszelle zu führen.According to the invention at least one light guide is integrated in the device for guiding the flow, which leads the light of the light source, preferably a light emitting diode or a laser diode, to the outside of the housing to avoid the emanating from the light sources aerodynamic turbulence and the smoke without delays from the smoke inlet into the To lead smoke cell.
Die Vorrichtung zur Strömungsführung der einströmenden Raumluft ist vorzugsweise aus mehreren rippen-, steg- oder strebenförmigen Bauteilen gebildet, welche beispielsweise aus einem Kunststoff gefertigt sind.The device for flow guidance of the incoming room air is preferably formed from a plurality of rib, web or strut-shaped components, which are made for example of a plastic.
In einer bevorzugten Ausführungsform des erfindungsgemäßen Rauchwarnmelders ist wenigstens eines der steg- oder strebenförmigen Bauteile der Vorrichtung zur Strömungsführung mit einem innenliegenden Bauraum versehen, welcher den Lichtleiter aufnimmt.In a preferred embodiment of the smoke alarm according to the invention at least one of the web or striven-shaped components of the device for flow guidance is provided with an internal space, which receives the light guide.
Die mit der Erfindung erzielbaren Vorteile bestehen insbesondere darin, dass eine Reduzierung von aerodynamischen Turbulenzen durch optische Signalanzeigen erreicht wird und ein negativer Einfluss, der sich insbesondere durch die Anordnung der Lichtquelle im Gehäuse des Rauchwarnmelders ergibt, kompensiert wird.The achievable with the present invention consist in particular in that a reduction of aerodynamic turbulence is achieved by optical signal displays and a negative influence, which results in particular by the arrangement of the light source in the housing of the smoke alarm is compensated.
Die Erfindung wird nachstehend anhand der in den Zeichnungen dargestellten Ausführungsbeispiele erläutert. Es zeigen:The invention will be explained below with reference to the embodiments illustrated in the drawings. Show it:
