Abstract
Description
Gegenstand der Erfindung ist ein Heizelement für Haartrockner, insbesondere für Handhaartrockner, dem die Aufgabe zugrunde liegt, eine gleichmäßige Temperatur des Heizdrahtes der gesamten Heizwicklung zu erreichen und die Überhitzung und damit das Glühen der vorderen Wickellagen zu verhindern.The invention relates to a heating element for hair dryers, in particular for handheld hair dryers, which the task is based on, a uniform temperature of the heating wire of the entire heating coil and to prevent overheating and thus the glowing of the front winding layers.
Erfindungsgemäß wird der Abstand der einzelnen Wickellagen der Heizspirale unterschiedlich ausgeführt, wobei sich die Abstände zur Auslaßöffnung hin, d.h. in Richtung des Luftaustritts, stetig oder sprunghaft vergrößern.According to the invention, the distance between the individual winding layers is of the heating coil designed differently, the distances to the outlet opening, i.e. in Increase direction of air outlet, steadily or suddenly.
In der Zeichnung ist ein Ausführungsbeispiel dargestellt: An exemplary embodiment is shown in the drawing:
Fig.l zeigt einen Handhaartrockner mit dem erfindungsgemäßen Heizelement, teilweise im Schnitt. Fig.2 zeigt ein weiteres Heizelement nach der Erfindung, Fig.3 zeigt eine weitere Ansicht zu Fig.2.Fig.l shows a handheld hair dryer with the inventive Heating element, partly in section. 2 shows a further heating element according to the invention, FIG. 3 shows a further view of FIG.

Der Handhaartrockner besteht aus dem Gehäuse ä mit Griff b und Luftaustrittsdüse c. Die Heizwicklung, eine Drahtspirale d, ist auf dem üblichen Heizkreuz e aus keramischem Werkstoff oder sonstigem Isoliermaterial aufgebracht. Die Abstände fl, f2, f3, f4, f5, f6 zwischen den Wickellagen vergrößern sich zur Auslaßöffnung g hin; hl, h2 sind die elektrischen Anschlüsse zur Wicklung, i ist das Netzkabel und j der Betätigungsschalter des Haartrockners. The handheld hair dryer consists of the housing ä with handle b and air outlet nozzle c. The heating coil, a wire spiral d, is on the usual heating cross e made of ceramic material or other insulating material applied. The distances fl, f2, f3, f4, f5, f6 between the winding layers enlarge towards the outlet opening g; hl, h2 are the electrical connections to the winding, i is the power cord and j is the hair dryer switch.
Die Abstände zwischen den Lagen der Heizspirale auf dem Heizkreuz sind beispielsweise ungleichmäßig oder nach der FormelThe distances between the layers of the heating coil on the heating cross are, for example, uneven or according to the formula
a + (n - 1) ka + (n - 1) k
gewählt, wobei a der Abstand zwischen zwei Wickellagen ist, η die Zählnummer der Spirale vom Lufteintritt gerechnet und k eine Konstante, z.B. 0,2mm.selected, where a is the distance between two winding layers, η is the number of the spiral from the air inlet calculated and k a constant, e.g. 0.2mm.
