Description

  

      Elektrischer        Röhrenheizkörper.       In bekannter Weise werden elektrische  Heizkörper in geschlossenen Röhren gelagert,  um sie gegen eindringenden Staub zu schüt  zen. Diese Röhren bestehen gewöhnlich aus  Eisen, weshalb durch geeignete Konstruktion  verhütet     werden,muss,    dass durch den Heiz  körper     Kra.ftlinienfelder    erzeugt werden, wel  che eine nachteilige     Phasenverschiebung    her  vorrufen können.

   Ferner soll der Heizkörper,  und zwar auch in heissem Zustande, gegen  alle gebräuchlichen Spannungen genügend  isoliert und wegen allfällig notwendig wer  dender Reparaturen leicht aus dem Schutz  rohr     herausgebaut    werden können; ebenso  soll derselbe viele Schaltungsmöglichkeiten  zulassen.  



  Gegenstand vorliegender Erfindung ist  nun ein     elektrischer    Röhrenheizkörper, der  den vorgenannten Bedingungen restlos ent  spricht, und zwar dadurch, dass das     Heiz-          organ,    - das aus einem beliebigen, zweck  entsprechenden Mittel bestehen kann, durch  einen isolierenden Träger gehalten wird.  



  In beiliegender Zeichnung ist ein Aus  führungsbeispiel des     Erfindungsgegenstandes     schematisch dargestellt.    Auf einer Eisenstange a, die eckig oder       rund.    sein kann, sind in bestimmten Abstän  den, beispielsweise 12     Centimeter,    Isolier  scheiben     b    aus einem feuerfesten Material an  geordnet,, welche durch Splinten c in ihrer  eingestellten Lage festgehalten werden. Diese       Scheiben    sind mit Vertiefungen d und  durchgehenden Öffnungen e von kleinerem  Durchmesser als demjenigen der Vertiefun  gen<I>d</I> versehen.

   In die Vertiefungen<I>d</I> wer  .den Isolierröhren     /=    aus feuerfestem Material,  beispielsweise drei am     Scheibeizumfang,    ge  lagert. Die durchgehenden     Öffnungen    der  Scheiben und die Isolierröhren bilden zu  sammen einen Kanal     g,    in welchem das  Heizmittel     h    eingebaut wird. An den Enden  der Isolierröhren sind die Anschlüsse i für  den Heizkörper angebracht.

   Durch     diese    An  ordnung ist eine äusserst gute Isolation     ge-          w        ährleistet,        i#        und        es        ist        möglich,        den        Heizkör-          per    auf alle     gebräuchlichen        Spannungen    zu  bauen und verschiedene     Schaltungen    vorzu  nehmen.

   Zufolge der     Zusammensetzung    der  Isolation aus     Einzelelementen        kann    die     Länge     des ganzen Heizkörpers beliebig gewählt  werden, und zufolge der Anordnung auf      einer     rührungsmetallstange    kann der Heiz  körper leicht in     .das        Seliutzrohr    hinein  geschoben und herausgezogen     werden.  



      Electric tubular heater. In a known manner, electric radiators are stored in closed tubes in order to protect them against the ingress of dust. These tubes are usually made of iron, which is why a suitable construction must be used to prevent force lines from being generated by the radiator, which can cause a disadvantageous phase shift.

   Furthermore, the radiator, even when hot, should be sufficiently insulated against all common voltages and, if repairs are necessary, can easily be removed from the protective tube; it should also allow many circuit options.



  The subject matter of the present invention is an electric tubular heating element which completely corresponds to the aforementioned conditions, namely in that the heating element, which can consist of any suitable means, is held by an insulating support.



  In the accompanying drawing, an exemplary embodiment from the subject of the invention is shown schematically. On an iron bar a that is angular or round. can be, are in certain Abstän the, for example 12 centimeters, insulating disks b made of a refractory material to be arranged, which are held by cotter pins in their set position. These disks are provided with recesses d and through openings e of a smaller diameter than that of the recesses <I> d </I>.

   The insulating tubes / = made of refractory material, for example three on the circumference of the pane, are stored in the depressions <I> d </I>. The through openings of the disks and the insulating tubes together form a channel g in which the heating means h is installed. The connections i for the radiator are attached to the ends of the insulating tubes.

   This arrangement ensures extremely good insulation, i # and it is possible to build the radiator on all common voltages and to make various switchings.

   As a result of the composition of the insulation from individual elements, the length of the entire radiator can be chosen arbitrarily, and as a result of the arrangement on a contact metal rod, the radiator can easily be pushed into .das Seliutzrohr and pulled out.
