Description

  

      Elektrische        Wärmevorrichtung.       Gegenstand der vorliegenden Erfindung  ist eine elektrische     Wärmevorrichtung,    z. B.  in Form eines     Bettwärmers,    eines     Platten-          wärmers    usw.,     mit    einem Gehäuse,     in    wel  chem ein elektrischer Widerstand und eine  denselben umgebende, aus wärmeaufspei  cherndem Material bestehende Füllung unter  gebracht     ist.     



  Das Wesen der Erfindung liegt darin,  dass. im genannten Gehäuse ein den Strom  kreis des elektrischen Widerstandes beherr  schendes, wärmeempfindliches Steuerorgan  eingebaut ist, das den genannten Stromkreis  unterbricht, sobald die durch den     stromdurch-          flossenen    Widerstand verursachte Wärmeent  wicklung ein bestimmtes Mass erreicht.  



  Auf der beiliegenden Zeichnung ist ein  Ausführungsbeispiel des     Erfindungsgegen-          standes    in Form     eines        Bettwärmers    veran  schaulicht.  



       Fig.    1 ist ein     Längsschnitt    durch den  Bettwärmer.  



       Fig.    2 ist ein     Querschnitt    durch densel  ben, und         Fig.    d ist     ein    Schema der elektrischen  Teile des     Bettwärmers.     



  Der Bettwärmer gemäss     Fig.    1     und    2 hat  ein zylindrisches Gehäuse a, in welchem in  zentrischer Anordnung ein z. B. aus     Steatit          bestehender        Isolierkörper    b vorgesehen     ist,     der offene Längsnuten aufweist, in welcher  ein     elektrischer    Heizwiderstand c     unterge-          bracht    ist. Der Isolierkörper b ist von  einer aus wärmeaufspeicherndem Material,  wie z. B. Quarzsand, bestehenden Füllung d  umgeben, in welcher auch     ein    mit einem  Gehäuse f versehener Thermostat eingebaut  ist.

   Das wärmeempfindliche     Steuerorgan     des Thermostaten ist an den dem Gehäuse f  isoliert angeordneten     Anschlussstellen    g an  geschlossen.  



  In     Fig.    8 ist das Schema der elektrischen  Teile des     Bettwärmers    gezeigt. Hieraus ist  ersichtlich,     dass    das wärmeempfindliche  Steuerorgan h des Thermostaten in Serie mit  dem     Heizwiderstand    c geschaltet ist. i     sind     zwei     Ansteckstifte,    über die der Stromkreis  des     Bettwärmers    beim Anstecken des letz-           teren    geschlossen wird.

   Bei angestecktem  Bettwärmer unterbricht der Thermostat in  bekannter Weise den Stromkreis des     Heiz-          widerstandes,    wenn die durch den letzteren  verursachte Wärmeentwicklung ein bestimm  tes Mass erreicht hat. Die     entwickelte    Wärme  wird vom Quarzsand aufgespeichert, so dass  der Bettwärmer während mehreren Stunden  warm bleibt.  



  Anstatt als Bettwärmer könnte der Er  findungsgegenstand auch als Plattenwärmer  ausgebildet sein, in welchem Falle das Ge  häuse     einen    rechteckigen     Querschnitt    auf  weisen würde.



      Electric heating device. The present invention is an electrical heating device, e.g. B. in the form of a bed warmer, a plate warmer, etc., with a housing in wel chem an electrical resistor and a surrounding same, made of wärmenspei cherndem material is placed under.



  The essence of the invention lies in the fact that a heat-sensitive control element which controls the circuit of the electrical resistance and which interrupts the circuit as soon as the heat generated by the resistance through which the current flows reaches a certain level is built into the housing mentioned.



  An exemplary embodiment of the subject of the invention in the form of a bed warmer is illustrated in the accompanying drawing.



       Fig. 1 is a longitudinal section through the bed warmer.



       Fig. 2 is a cross section through the same, and Fig. D is a schematic of the electrical parts of the bed warmer.



  The bed warmer according to FIGS. 1 and 2 has a cylindrical housing a, in which a z. B. made of steatite insulating body b is provided, which has open longitudinal grooves in which an electrical heating resistor c is housed. The insulating body b is made of a heat-accumulating material, such as. B. quartz sand, surrounding existing filling d, in which a thermostat provided with a housing f is installed.

   The heat-sensitive control element of the thermostat is closed at the connection points g which are insulated from the housing f.



  In Fig. 8 the schematic of the electrical parts of the bed warmer is shown. It can be seen from this that the heat-sensitive control element h of the thermostat is connected in series with the heating resistor c. i are two pins that close the circuit of the bed warmer when the latter is plugged in.

   When the bed warmer is plugged in, the thermostat interrupts the circuit of the heating resistor in a known manner when the heat generated by the latter has reached a certain level. The developed heat is stored by the quartz sand, so that the bed warmer stays warm for several hours.



  Instead of being a bed warmer, the subject of the invention could also be designed as a plate warmer, in which case the housing would have a rectangular cross-section.
