Description

Brandschutz- und Brandlöscheinrichtung für wasserführende Haushaltgeräte Fire protection and fire extinguishing equipment for water-bearing household appliances
Die Erfindung betrifft eine Brandschutz- und Brandlöscheinrichtung für wasserführende Haushaltgeräte.The invention relates to a fire protection and fire extinguishing device for water-bearing household appliances.
Haushaltgeräte, die mehrere Stromverbraucher, wie beispielsweise Motoren, Heizungen etc. aufweisen unterliegen üblicherweise keiner individuellen Überprüfung ihrer elektrischen Sicherheit. Zur Vermeidung von Beschädigungen des Haushaltgerätes in Folge von Überspannung weisen Haushaltgeräte regelmäßig Sicherungseinrichtungen auf, die bei- spielsweise einen in Porzellan oder Keramik eingebrachten Sicherungsstift aufweisen, der bei Erreichen einer bestimmten Stromstärke durchglüht und so das Haushaltgerät vor weiterem Schaden bewahrt, insbesondere Schwelbrände oder dergleichen.Household appliances that have multiple electricity consumers, such as motors, heaters, etc. are usually not subject to individual checking of their electrical safety. In order to avoid damage to the household appliance as a result of overvoltage, household appliances regularly have safety devices which, for example, have a safety pin inserted in porcelain or ceramic which glows when a certain current is reached and thus protects the household appliance from further damage, in particular smoldering fires or the like.
Da bei der Herstellung von elektrischen Geräten für den Haushalt auch entzündbare und entflammbare Werkstoffe verwendet werden, kann ein erhöhtes Risiko bestehen, dass diese Werkstoffe bei einem Kurzschluß oder einem Verschleiß von elektrischen Leitern in Brand geraten. Zum Löschen dieser so entstandener Brände ist aus der DE 38 09 754 A1 eine Vorrichtung mit einem Behälter für einen Feuerlöschstoff bekannt, der sich in Anwesenheit einer Flamme oder beim Ansteigen der Umgebungstemperatur bis über einen Grenzwert hinaus selbsttätig öffnet, um den Feuerlöschstoff mittelbar oder unmittelbar auf die feuergefährdeten bzw. zu schützenden Partien des Gerätes auszugießen. Hierbei kann z.B. die Anordnung so getroffen sein, dass die Behälter, vorzugsweise mehrere, jeweils Feuerlöschstoff enthaltende Zellen besitzen, die zweckmäßigerweise im Bodenbereich Bohrungen besitzen, die von einer Schutzhülle oder einem z.B. membranartigen Häutchen abgeschlossen sind, die bzw. das bei einer vorbestimmten Temperatur zum Öffnen der Bohrungen zerstört wird und hierbei den Feuerlöschstoff austreten lässt.Since flammable and flammable materials are also used in the manufacture of electrical household appliances, there is an increased risk that these materials will catch fire if there is a short circuit or wear of electrical conductors. DE 38 09 754 A1 discloses a device for extinguishing these fires, which has a container for a fire extinguisher and which opens automatically in the presence of a flame or when the ambient temperature rises above a limit value to directly or indirectly open the fire extinguisher pour out the parts of the device that are at risk of fire or are to be protected. Here, e.g. the arrangement must be such that the containers preferably have several cells, each containing fire extinguishing agent, which expediently have bores in the bottom area which are covered by a protective cover or a e.g. Membrane-like cuticles are completed, which is destroyed at a predetermined temperature to open the holes and thereby allows the fire extinguishing agent to escape.
Als nachteilig hat sich bei dieser Vorrichtung erwiesen, dass sich die Bohrungen erst ab einer bestimmten Temperatur öffnen, d.h. erst ab Temperaturen, die die abschließende Membran der Bohrungen schmilzt. Für diesen Schmelzvorgang ist es jedoch notwendig, dass über die Luft eine ausreichend hohe Temperatur übertragen werden muß, so dass .am Brandherd bereits eine sehr viel höhere Temperatur vorherrschen muß und folglich erst dann mit dem Löschen begonnen wird, wenn bereits ein gewisser Zerstöruήgsgrad erreicht ist.It has been found to be disadvantageous in this device that the bores only open above a certain temperature, ie only from temperatures that the closing membrane of the bores melts. For this melting process, however, it is necessary that a sufficiently high temperature must be transferred via the air, so that a much higher temperature must already prevail at the source of the fire and consequently Extinguishing is only started when a certain degree of destruction has already been reached.
Auch wenn sich im Verhältnis zu einer Zerstörung mehrerer Haushaltgeräte, beispielsweise in der Küche, der Verlust eines einzelnen Haushaltgerätes als verhältnismäßig gering erweist, so ist es dennoch wünschenswert auch dieses Haushaltgerät, sofern möglich, vor einer Totalzerstörung zu bewahren. Da die Vorrichtung gemäß DE 38 09 754 A1 jedoch erst bei einer bereits stattgefundenen Teilzerstörung der Elektrik Einsatz findet, ist bereits ein wesentlicher Schaden bei diesem elektrischen Haushaltgerät entstanden.Even if the loss of a single household appliance proves to be relatively small in relation to the destruction of several household appliances, for example in the kitchen, it is nevertheless desirable, if possible, to protect this household appliance from total destruction. However, since the device according to DE 38 09 754 A1 is only used when the electrical system has been partially destroyed, this electrical household appliance has already suffered substantial damage.
Aufgabe der vorliegenden Erfindung ist es daher, eine Brandschutz- und Brandlöscheinrichtung für ein wasserführendes Haushaltgerät bereitzustellen, welche bereits zu Beginn einer Fehlfunktion mit potentieller Brandfolge für das Haushaltgerät Maßnahmen ergreift, um sowohl das Haushaltgerät vor weiterem Schaden zu schützen, als auch einer Brandgefahr vorzubeugen und einen entstandenen Brand zu löschen.The object of the present invention is therefore to provide a fire protection and fire extinguishing device for a water-carrying household appliance, which takes measures at the beginning of a malfunction with a potential fire sequence for the household appliance, both to protect the household appliance from further damage and to prevent a fire risk and extinguish a fire.
Erfindungsgemäß wird diese Aufgabe durch eine Brandschutz- und Brandlöscheinrichtung mit den Merkmalen gemäß Anspruch 1 gelöst. Vorteilhafte Ausgestaltungen der vorliegenden Erfindung sind in den Unteransprüchen gekennzeichnet.According to the invention this object is achieved by a fire protection and fire extinguishing device with the features according to claim 1. Advantageous embodiments of the present invention are characterized in the subclaims.
Mit der erfindungsgemäßen Brandschutz- und Brandlöscheinrichtung für wasserführende Haushaltgeräte wird ein Ausbreiten von Schwelbränden, die von elektrischen Fehlern ausgehen, vermieden, da die bei einem Schwelbrand entstehenden Gase durch den Gassensor detektiert werden und ab einer gewissen Menge eines Leitgases, beispielsweise Kohlenmonoxyd (CO) und/oder Chlor (Cl) innerhalb des Haushaltgerätes ein Signal er- zeugt wird, welches zu einem Abschalten der elektrischen Versorgung innerhalb des Haushaltgerätes, sowie zu einer Aktivierung einer Wasserspruhanlage zum Löschen im Inneren des Haushaltgerats führt.With the fire protection and fire extinguishing device according to the invention for water-bearing domestic appliances, spreading of smoldering fires that are caused by electrical faults is avoided, since the gases that arise during a smoldering fire are detected by the gas sensor and from a certain amount of a guide gas, for example carbon monoxide (CO) and / or chlorine (Cl) a signal is generated within the household appliance, which leads to a shutdown of the electrical supply within the household appliance, as well as to an activation of a water spray system for extinguishing inside the household appliance.
Mit der erfindungsgemäßen Brandschutz- und Brandlöscheinrichtung für wasserführende Haushaltgeräte wird erreicht, dass ein Schwelbrand, ein offener Brand oder Rauch erkannt wird und das wasserführende Haushaltgerät unverzüglich vom elektrischen Netz getrennt wird und somit die elektrische Zündenergie für den Brand oder Schwelbrand ge- nommen wird. Bei Ausbruch eines Brandes wird weiterhin die Wasserspruhanlage aktiviert, um beispielsweise durch einen Sprühnebel Brände zu löschen.With the fire protection and fire extinguishing device according to the invention for water-bearing domestic appliances, a smoldering fire, an open fire or smoke is recognized and the water-bearing household appliance is immediately disconnected from the electrical network, and thus the electrical ignition energy for the fire or smoldering fire is is taken. If a fire breaks out, the water spray system will continue to be activated, for example to extinguish fires with a spray.
Bei Verwendung der erfindungsgemäßen Brandschutz- und Brandlöscheinrichtung für wasserführende Haushaltgeräte werden als erste Sicherheitsstufe durch den Gassensor Rauchentwicklungen, die im wesentlichen auf Polyethylen (PE), Polypropylen (PP), Polyamid (PA), Polyvinylchlorid (PVC) oder Polystyrol (PS) zurückzuführen sind, frühzeitig erkannt, da beim Verbrennen dieser Kunststoffe Kohlenmonoxyd (CO) und/oder Chlor (Cl) freigesetzt wird. Durch die Netzabschaltung wird ein Übergreifen von Kriechströmen von bzw. zu benachbarten elektrischen Geräten verhindert, die sich im selben Stromkreis be- finden. In einer zweiten Stufe wird die Wasserspruhanlage aktiviert und beispielsweise ein Sprühnebel oder dergleichen im Innenraum des wasserführenden Haushaltgerats erzeugt. Zur Vermeidung eines ebenfalls unerwünschten Wasserschadens, der durch die Erzeugung des Sprühnebels entstehen würde, weist das wasserführende Haushaltgeräte eine Bodenwanne auf, die über ein Schwimmerelement ein Ansteigen des in der Boden- wanne aufgefangenen Wassers registriert und bei Erreichen eines vorbestimmten Schaltniveaus den Wasserzulauf für die Wasserspruhanlage sperrt. Mit der vorliegenden Erfindung ist eine Brandschutz- und Brandlöscheinrichtung für ein wasserführendes Haushaltgerät bereitgestellt, welche bereits zu Beginn einer Fehlfunktion mit potentieller Brandfolge für das Haushaltgerät Maßnahmen ergreift, um sowohl das Haushaltgerät vor weite- rem Schaden zu schützen, als auch einer Brandgefahr vorzubeugen und einen entstandenen Brand zu löschen.When using the fire protection and fire extinguishing device according to the invention for water-carrying household appliances, the gas sensor detects smoke developments as a first safety level, which are essentially due to polyethylene (PE), polypropylene (PP), polyamide (PA), polyvinyl chloride (PVC) or polystyrene (PS) , recognized early, as carbon monoxide (CO) and / or chlorine (Cl) is released when these plastics are burned. The power cut-off prevents leakage currents from spreading from or to neighboring electrical devices located in the same circuit. In a second stage, the water spray system is activated and, for example, a spray or the like is generated in the interior of the water-carrying household appliance. In order to avoid any undesirable water damage that would result from the generation of the spray mist, the water-carrying household appliance has a floor pan that registers an increase in the water collected in the floor pan via a float element and, when a predetermined switching level is reached, the water supply for the water spray system locks. The present invention provides a fire protection and fire extinguishing device for a water-bearing household appliance, which already takes measures at the beginning of a malfunction with a potential fire sequence for the household appliance in order to protect the household appliance from further damage, as well as to prevent a fire risk and prevent one extinguish the fire.
Vorteilhafterweise ist der Gassensor im Bodenbereich und/oder einer Tür des Haushaltgerätes angeordnet.The gas sensor is advantageously arranged in the floor area and / or a door of the household appliance.
