Description

Die Erfindung bezieht sich auf ein elektrisches Heizkissen, bei dem der Heizleiter allseitig von einem leitenden Überzug umgeben ist. Dieser Überzug wird erfindungsgemäß bei Einschaltung des Stromes geerdet. Um die Biegsamkeit des Kissens nicht zu vermindern, kann insbesondere metallisiertes Gewebe oder Gewebe, das von einem feinen Drahtgeflecht durchsetzt ist, verwendet werden. Auch bei einem Feuchtwerden des Kissens, wie es beim Gebrauch nie zu vermeiden ist (alle Mittel, die einen Feuchtigkeitsschutz durch Gummi- oder Ölleinwändüberzüge zu erreichen suchen, haben sich in-The invention relates to an electric heating pad in which the heating conductor is surrounded on all sides by a conductive coating. This coating is according to the invention grounded when the power is switched on. In order not to reduce the flexibility of the pillow, In particular, metalized fabric or fabric interspersed with a fine wire mesh can be used. Even if the pillow gets wet, which can never be avoided during use (all means that provide moisture protection trying to achieve by means of rubber or oil canvas covers, have

«5 folge Brüchigwerdens während des Gebrauches nicht bewährt), ist durch diese Maßnahme eine Gefahr vermieden, die besonders dann auftritt, wenn das Heizkissen in sogenannten gefährdeten Räumen (in denen die“5 consequence of becoming brittle during use not proven) is due to this measure avoided a risk that occurs especially when the heating pad is in so-called endangered rooms (in which the

so Berührung geerdeter Teile möglich ist) benutzt wird.so that contact with earthed parts is possible).

Es ist an sich bekannt, elektrisch beheizte Geräte zu erden und solche Geräte, insbesondere Haushaltungsgeräte, wie BügeleisenIt is known per se to ground electrically heated devices and such devices, in particular Household appliances such as irons

o. dgl., mit geerdeten Überzügen zu versehen. Jedoch ist bisher nicht versucht worden, Heizkissen, bei denen die Hochspannungsgefahr viel größer als bei den genannten Geräten ist, mit einer leitenden Hülle zu umgeben, die an .ein bei Anschluß des Heizdrahtes an die Spannungsquelle zwangsläufig mit Erde verbundenes Kontaktstück angeschlossen ist.or the like, to be provided with earthed coatings. However, no attempt has been made to date to use heating pads, where the risk of high voltage is much greater than with the devices mentioned, to be surrounded with a conductive sheath, which at .ein when connecting the heating wire to the Voltage source is necessarily connected to the contact piece connected to earth.

Die Abbildungen zeigen Ausführungsbeispiele der Erfindung, und zwar ist in Abb. 1 ein Heizkissen mit einer engmaschigen, in Abb. 2 ein solches mit einer weitmaschigen Umhüllung 1 des Heizleiters dargestellt. Die Erdleitung wird innerhalb der Anschlußschnur 2 zu dem dreipoligen Stecker 3 geführt. Die Leitung 4 führt zu einem in der 4" Abbildung nicht dargestellten Regler.The figures show exemplary embodiments of the invention, namely in Fig. 1 a heating pad with a close-meshed one, in Fig. 2 one with a wide-meshed one Sheath 1 of the heating conductor shown. The earth wire is inside the connecting cord 2 led to the three-pin plug 3. Line 4 leads to one of the 4 " Figure not shown regulator.
