Abstract

A safety device for electrically operated apparatuses, especially for domestic appliances such as hand-held hair driers, heated cushions and electric blankets, sunray lamps (UV lamps), electrical tools for do-it-yourself enthusiasts and the like. In order to increase the electrical safety, particularly during use in damp rooms, a protective conductor is provided as a safety device, which is passed through the apparatus as a loop and is monitored for interruption, using electronic means.

Description

Sicherheitsvorrichtung für elektrisch betriebene Geräte Die Erfindung betrifft eine Sicherheitsvorrichtung für elektrisch betriebene Geräte, insbesondere für Haushaltsgeräte, wie Hand-Haartrockner, Heizkissen und -decken, Höhensonnen, Elektrowerkzeuge für den Heimwerker und dgl Beim Benutzen von elektrisch betriebenen Geräten vor allem in feuchten Räumen, z.B. in Bade- und Waschräumen, oder falls solche Geräte bei leichtsinniger Handhabung mit Wasser direkt in Berührung gebracht werden, z.B. ein in der Badewanne benutzter Haartrockner fällt ins Badewasser, ergeben sich für den betreffenden Benutzer erhebliche Gefahren, die bei der zuletzt genannten Möglichkeit mit Sicherheit sogar tödlich verlaufen. Safety device for electrically operated devices The invention relates to a safety device for electrically operated devices, in particular for household appliances, such as handheld hair dryers, heating pads and blankets, sunsets, Power tools for the do-it-yourselfer and the like when using electrically operated Devices especially in damp rooms, e.g. in bathrooms and washrooms, or if such devices brought into direct contact with water if handled carelessly e.g. a hair dryer used in the bathtub falls into the bathwater significant dangers for the user in question, as in the case of the last-mentioned Possibility to be fatal with certainty.

Aufgabe der vorliegenden Erfindung ist es deshalb, die elektrische Sicherheit bei elektrisch betriebenen Geräten für den Benutzer weiter zu verbessern, so daß einerseits auch bei Benutzung in feuchten Räumen oder bei direkter Berührung mit Wasser sich keine Gefahr für den Benutzer ergibt und andererseits bei einem Kontakt mit Feuchtigkeit an den stromführenden elektrischen Bauteilen eine sofortige Unterbrechung des Speisestromkreises des Gerätes herbeigeführt wird Die gestellte Aufgabe wir(l gemäß der Erfindung dadurch gelöst9 daß als Sicherheitsvorrichtung ein als Schleife durch das Gerät geführter Schutzleiter dient, der mit elektronischen Mitteln auf Unterbrechung überwacht wird Durch diese Maßnahme wird erreicht9 daß bei Zutritt von Feuchtigkeit bzw Wasser die Zuleitungssicherung zum Ansprechen gebracht und dadurch der Speisestromkreis augenblicklich unten brochen wirdO Eine zweckmäßige Weiterbildung der Erfindung wird darin ge sehen, daß zur flächenmäßigen Vergrößerung des Schutzleiters zusätzliche metallische Fahnen bzw Elektroden vorgesehen sind9 die vornehmlich in die Nähe von unter Spannung stehenrIen elektrischen Teilen angeordnet sind Durch diese Maßnahme wird die Abschaltsicherheit bei Eindringen von Feuchtigkeit in das betreffende Gerät noch weiter erhöht Der mit Fahnen bzw. Elektroden ausgerüstete Schutzleiter kann auch als eine Art Käfig ausgebildet sein, der die unter Spannung stehenden elektrischen Geräteteile, wie z.B. bei einem Haartrockner den Heizkörper und Gebläse-Motor, umgibtThe object of the present invention is therefore the electrical To further improve the safety of electrically operated devices for the user, so that on the one hand also when used in damp rooms or in direct contact with Water poses no danger to the user and, on the other hand, in the event of contact an immediate interruption with moisture on the live electrical components the supply circuit of the device is brought about The task we (l solved according to the invention in that a safety device as a loop Protective conductor guided through the device is used, which is activated by electronic means Interruption is monitored This measure ensures9 that upon entry caused by moisture or water, the feed line fuse and as a result, the supply circuit is immediately interrupted below. A suitable one Further development of the invention is seen in ge that for areal enlargement additional metallic flags or electrodes are provided on the protective conductor 9 which are primarily located in the vicinity of live electrical parts By this measure, the shutdown security in the event of moisture penetration in the device in question even further increased The one equipped with flags or electrodes Protective conductor can also be designed as a kind of cage, which is under tension standing electrical device parts, e.g. the radiator of a hair dryer and fan motor, surrounds
