  Elektrischer Ofen mit künstlicher Luftumwälzung für Raumheizung.    Gegenstand, der Erfindung bildet ein     elek-          triseher    Ofen mit     hiinstlicher    Luftumwälzung  für     Raumheizung,    welcher Ofen sich     üadureh          au:

  ,zeiehnet,    dass er im     Grundriss,    kreisförmig       begrenzt        ist.    und in seinem Innern ein mit  elektrischem Antrieb und vertikaler Achse  versehenes Flügelrad aufweist und     -d'ae     Ganze derart     @aufgebaut    ist,     d@ass    das ange  triebene Flügelrad über dem Ofen befind  liehe Luft     ansaugt    und durch einen. rings um       d;'rs    Flügelrad     an,ge@ordneten        elektrischen     Heizkörper in     horizontaler        Riehtung    nach  allen Seitens nach aussen aus dem Ofen be  fördert.  



  Die beiliegende Zeichnung     etellt    ein Aus  führungsbeispiel des     Erfindungsgegenstan-          des        schematisch    dar,     und    zwar zeigt;       Fig.    1 eine Ansicht des. Ofens,       Fig.    2 einen     Quersehnitt    nach der Linie       C-D    in     Fig.    3 und       Fig.    3 einen Querschnitt     nach        ,der    Linie       .,1-B    in     Fig.    2.  



  Der Gehäuseoberteil 1 mit einer nach  oben     gerichteten        Ausbuchtung    la -weist  auf dem Umfang eines     zylindrischen        Mit-          telteils.        1b    gleichmässig     verteilte        Vent.ila-          tionseintrittsöffnungen    4 auf.

   Ein Elektro  motor 2 und, ein an     dessen    unterem     Wellen-          en.d.e    sitzendes, mit     vertikaler    Achse     versehe-          nes    Flügelrad 3 sind     koaxial    zum Teil 1 an       diesem,        befestigt.    Der Oberteil 1 ist durch  mehrere an letzterem befestigte Stützen 5 mit  .dem nicht     durchbrochenen    Gehäuseunterteil 1         verbunden,    von welchen Stützen drei     .länger     als die übrigen     -sind    und zur Befestigung von  drei Füssen 10 .dienen.

   Die Distanzierung -der  Teile 1, 1' voneinander     erfolgt    durch von -den       Verbindungsstützen    5     durchfahrene        Hülsen     11, 12, 13, die letzteren aus     elektrischem     Isolierstoff, und     Leitblechen    6, 7. Die Hülsen       1.3,    tragen in Rillen die     Heizwendel    9, welch  letztere durch die Bleche 6 bzw. 7 nach unten  bzw. eben     abgeschirmt        sind.    Zwischen den  Peripherien -der Bleche ss und 7 ist ein Draht  geflecht 8 gespannt, das die Heizwendel 9  gegen Beschädigung von aussen schützt.

    Durch     Muttern    5a auf den Stützen 5 werden  die Teile 1, 11, 7, 13, 6,     1'2    und 10 zusam  mengehalten. Zum Tragen des     Ofens    ist am  Oberteil 1 ein nicht     gezeigter    Bügel ange  bracht.

   Die     Gesamthöhe        -des    Ofens beträgt       höchstens    2:0 cm.     Im        Betrieb    wird zu erwär  mende Luft über dem Oberteil 1 des Ofens  durch     die,b'ffnungen    4 angesaugt und unten  seitlich durch -den rings um     .das.        Flügelrad.    3  angeordneten elektrischen Heizkörper 9 in  horizontaler Richtung     naeh    allen Seiten er  wärmt durch das Gitter 8 nach aussen aus  .dem im     Grupdriss    gesehen kreisförmig be  grenzten Ofen gestossen.

   Die im     Abstaed    von  den Gehäuseteilen 1' bzw. 1     ang"ebraehten     Bleche 6 und 7 tragen dazu bei,     dass    ,die Tem  peratur des. Gehäuses nicht zu hoch steigt.  Die     wärmeisolierenden    Füsse 10 können eben  falls zum Tragendes     Ofens    dienen. Die     blff-          nungen    4 liegen     höher    als die     Luftaustritts-          öffnungen    im     Gitter    B.



  Electric oven with artificial air circulation for space heating. The subject of the invention is an electric oven with internal air circulation for space heating, which oven can be:

  , shows that it is limited in the ground plan, circular. and in its interior an impeller provided with an electric drive and a vertical axis and the whole thing is constructed in such a way that the driven impeller sucks in air above the furnace and through a. All around the impeller, arranged electric heating element is conveyed out of the furnace in a horizontal direction on all sides.



  The accompanying drawing shows an exemplary embodiment of the subject matter of the invention schematically, namely shows; 1 shows a view of the furnace, FIG. 2 shows a cross section along the line C-D in FIG. 3 and FIG. 3 shows a cross section along the line 1-B in FIG.



  The upper housing part 1 with an upwardly directed bulge la -points on the circumference of a cylindrical central part. 1b evenly distributed ventilation inlet openings 4.

   An electric motor 2 and an impeller 3, which is seated on its lower shaft end and provided with a vertical axis, are fastened coaxially to part 1 on the latter. The upper part 1 is connected to the non-perforated lower housing part 1 by several supports 5 attached to the latter, of which three supports are .longer than the others and are used to attach three feet 10.

   The spacing of the parts 1, 1 'from one another is carried out by sleeves 11, 12, 13 traversed by the connecting supports 5, the latter made of electrical insulating material, and guide plates 6, 7. The sleeves 1.3 carry the heating coil 9 in grooves, which latter are shielded by the sheets 6 and 7 downwards or evenly. A wire braid 8 is stretched between the peripheries of the sheets and 7, which protects the heating coil 9 against damage from the outside.

    Parts 1, 11, 7, 13, 6, 1'2 and 10 are held together by nuts 5a on supports 5. To carry the furnace, a bracket, not shown, is attached to the upper part 1.

   The total height of the furnace is at most 2: 0 cm. During operation, air to be heated is sucked in above the upper part 1 of the furnace through the openings 4 and at the bottom through the sides around the. Impeller. 3 arranged electric radiator 9 in the horizontal direction near all sides it warms through the grid 8 to the outside from .dem seen in the group plan circular be bordered furnace encountered.

   The metal sheets 6 and 7, which are spaced apart from the housing parts 1 'and 1, help ensure that the temperature of the housing does not rise too high. The heat-insulating feet 10 can also serve to support the furnace. The openings 4 are higher than the air outlet openings in grille B.
