Abstract

The electrical single-point radiation heater is produced by means of a solid heating element and a cup-shaped concave mirror focussed on the point concerned. Newly developed materials allow the heating element to have no protection against possible damage, which has traditionally been necessary where helical heating elements and quartz coverings have been used. Basically, a heating element of solid material (2) is mounted above base (1), but protected from it by a flat heat shield (4), and is surrouned by a concave mirror (3) which focusses the heat on one point (F). Electric terminals under the element are provided.

Description

Beschreibung Elektrisc=rr Punkt-Strahlungsheizer.Description Elektrisc = rr point radiant heater.

Die Neuerung befaßt sich mit einem elektrischen Heizgerät mit dem eine annähernd punktförmige, intensive Heizquelle erzielt wird.The innovation deals with an electric heater with the an approximately punctiform, intensive heat source is achieved.

Mit dem bisher auf dem Markt befindlichen Gerät wurde dies mit einem Heizkörper mit offenliegender Heizspirale und Quarzschutzkappe erzielt. Die offene Heizspirale mit Quarzschutzkappe machte zusätzlich eine Schutzeinrichtung gegen Berührung notwendig.With the device previously on the market, this was done with a Radiator with exposed heating coil and quartz protection cap achieved. The open one Heating coil with quartz protective cap also made a protective device against Touch necessary.

Bei der Neuerung, die in beigefügter Abbildung dargestellt ist, wird ein mit einem temperaturbeständigen Feststoff bemanteltes Heizelement verwendet. Neu entwickelte Werkstoffe ergaben die Möglichkeit ein Heizelement mit der notwendigen Lebensdauer herzustellen. Das neue Heizelement ist elektrisch berührsicher. In einem Rohr aus temperaturbeständigem Material ist der Heizleiter in einem hochtemperaturbeständigem Isolationswerkstoff eingebettet und hoch verdichtet. Die Verwendung eines derartigen Heizelementes ermöglicht einen optimalen Wirkungsgrad und vereinfacht die Konstruktion des Gerätes.In the case of the innovation, which is shown in the attached illustration, a heating element sheathed with a temperature-resistant solid is used. Newly developed materials made it possible to have a heating element with the necessary Establish service life. The new heating element is electrically safe to touch. In one Tube made of temperature-resistant material is the heating conductor in a high-temperature-resistant Insulation material embedded and highly compressed. The use of such a Heating element enables optimal efficiency and simplifies the construction of the device.

Die Abbildung zeigt den Erfindungsgegenstand und ist in einem schematischen Axialschnitt dargestellt. Auf dem Fuß (1) ist das mit einem Feststoff bemantelte Heizelement senkrechter Stellung montiert. Das Heizelement (2) ist von einem becherförmigen Hohlspiegel (3) umgeben. Der Hohlspiegel ist so ausgebildet, daß möglichst viele vom Heizelement abgehenden Wärmestahlen reflektiert und in einem Punkt F oberhalb des Heizelements gesammelt werden. Um eine Übertragung der Wärme auf den Fuß des Gerätes zu verhindern ist das Abstrahlblech (4) angebracht. Das auswechselbare Heizelement wird mittels zwei Kontaktstiften in der Steckvorrichtung (5) befestigt.The figure shows the subject of the invention and is in a schematic Axial section shown. On the foot (1) is coated with a solid Heating element mounted in a vertical position. The heating element (2) is of a cup-shaped Surrounding the concave mirror (3). The concave mirror is designed so that as many as possible from the heating element outgoing heat rays are reflected and at a point F above of the heating element are collected. To ensure a transfer of heat to the foot of the To prevent the device, the radiation plate (4) is attached. The replaceable heating element is attached to the connector (5) using two contact pins.
