Description

Die Krempenflächen 2a, 2b sind ferner etwa mindestens halb so groß wie die dem Heizstab 1 zugewandte Reflektoroberfläche. The rim surfaces 2a, 2b are also approximately at least half as large like the reflector surface facing the heating rod 1.

Claims (1)

Patentanspruch: Heizstrahler, bestehend aus einem elektrischen Heizstab und einem Reflektor, der randseitig krempenartig umgebogen ist, wobei die Krempenflächen des Reflektors auf der Frontseite ein hohes Emissionsvermögen im Infrarotbereich besitzen, nach Patent 2325775, dadurch gekennzeichn e t, daß die ein hohes Emissionsvermögen besitzenden Krempenflächen (2a, 2b) mindestens halb so groß sind wie die dem Heizstab (1) zugewandte Reflektoroberfläche. Claim: Radiant heater, consisting of an electric heating rod and a reflector which is bent over like a brim at the edge, the brim surfaces of the reflector on the front side has a high emissivity in the infrared range have, according to patent 2325775, characterized in that they have a high emissivity brim surfaces (2a, 2b) that have their own are at least half as large as those of the heating rod (1) facing reflector surface. Die Erfindung bezieht sich auf einen Heizstrahler nach dem Oberbegriff des Anspruches. The invention relates to a radiant heater according to the preamble of the claim. Aufgabe der Erfindung ist es, den vorgenannten Heizstrahler hinsichtlich seines Wirkungsgrades noch weiter zu verbessern. The object of the invention is to provide the aforementioned radiant heater with regard to to improve its efficiency even further. Die gestellte Aufgabe wird durch die im kennzeichnenden Teil des Anspruches angegebenen Maßnahmen gelöst. Diese Ausbildung hat den Vorteil, daß dem Reflektor noch mehr Wärme als bisher entzogen und an den Krempenflächen in Nutzstrahlung umgesetzt wird. The task set is indicated by the characterizing part of the Claim specified measures resolved. This training has the advantage that the Reflector withdrew even more heat than before and used radiation on the brim surfaces is implemented. Ein Ausführungsbeispiel ist in der Zeichnung schematisch in einer Seitenansicht dargestellt. An exemplary embodiment is shown schematically in the drawing Side view shown. Der Heizstrahler besteht aus einem elektrischen Heizstab 1 und einem Reflektor 2. The radiant heater consists of an electric heating rod 1 and one Reflector 2. Der Reflektor 2 ist randseitig krempenartig umgebogen. Die Krempenflächen 2a, 2b besitzen auf ihrer Frontseite ein hohes Emissionsvermögen im Infrarotbereich. The reflector 2 is bent over like a brim at the edge. The brim surfaces 2a, 2b have a high emissivity in the infrared range on their front side.
