Description

Die Erfindung bezieht sich auf ein Elektro-Wärmespeicherheizgerät nach dem Oberbegriff des Anspruches 1.The invention relates to an electric heat storage heater according to the preamble of claim 1.

Es ist bereits ein Elektro-Wärmespeicherheizgerät der im Oberbegriff des Anspruches 1 genannten Art bekannt (DE-A1 19 41 869).There is already an electric heat storage heater known in the preamble of claim 1 (DE-A1 19 41 869).

Aufgabe der Erfindung ist es, das Elektro-Wärmespeicherheizgerät der im Oberbegriff des Anspruches 1 genannten Art so auszubilden, daß Übertemperaturen der Luft in dem Raume vermieden werden,in dem sich der Zusatzheizkörper befindet.The object of the invention is to design the electric heat storage heater of the type mentioned in the preamble of claim 1 in such a way that excess temperatures of the air are avoided in the room in which the additional heating element is located.

Die gestellte Aufgabe wird erfindungsgemäß durch die im kennzeichnenden Teil des Anspruches 1 angegebene Ausbildung gelöst.The object is achieved by the training specified in the characterizing part of claim 1.

Zweckmäßige Weiterbildungen des Erfindungsgegenstandes sind in den Ansprüchen 2 und 3 angegeben.Expedient developments of the subject matter of the invention are specified in claims 2 and 3.

Die gefundene Lösung hat insbesondere den Vorteil, daß der Regler sehr schnell auf Übertemperatur des Zusatzgerätes und/oder des Speicherkernes ansprechen kann.The solution found has the particular advantage that the controller can respond very quickly to excess temperature of the additional device and / or the memory core.

Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung rein schematisch dargestellt, die eine Seitenansicht des unteren und mittleren Teils eines Wärmespeicherheizgerätes im Schnitt zeigt. Bei dem dargestellten Wärmespeicherheizgerät ist ein wärmeisolierter Mantel mit 1 bezeichnet.An embodiment of the invention is shown purely schematically in the drawing, which shows a side view of the lower and middle part of a heat storage heater in section. In the heat storage heater shown, a heat-insulated jacket is designated by 1.

Der Mantel 1 weist auf seiner Rückseite eine Kaltluft-Einlaßöffnung 2 und auf seiner Frontseite eine Warmluft-Auslaßöffnung 3 auf.The jacket 1 has a cold air inlet opening 2 on its rear side and a warm air outlet opening 3 on its front side.

Zwischen dem Mantel 1 und einem Speicherkern 4 sind senkrechte Luftführungskanäle 5, 5' vorgesehen, die mit waagrechten Kanälen 6 des Speicherkerns 4 in Verbindung stehen.Between the casing 1 and a storage core 4, vertical air guiding channels 5, 5 'are provided, which are connected to horizontal channels 6 of the storage core 4.

Im Speicherkern 4 ist senkrecht eine Heizwiderstandseinrichtung 7 angeordnet.A heating resistor device 7 is arranged vertically in the memory core 4.

Der Speicherkern 4 ist auf einer Konsole 8 abgetragen.The memory core 4 is removed on a console 8.

Zwischen einer Säule 8a der Konsole 8 und der Wand des Mantels 1, in der sich die Kaltluft-Einlaßöffnung 2 befindet, ist ein Kaltluftraum 9 vorgesehen, der ein Gebläse 1o enthält.Between a column 8a of the console 8 and the wall of the casing 1, in which the cold air inlet opening 2 is located, a cold air space 9 is provided which contains a fan 10.

Zwischen der Säule 8a der Konsole 8 und der Wand des Mantels 1, in der sich die Warmluft-Auslaßöffnung 3 befindet, ist ein Luftmischraum 11 angeordnet. In den Luftmischraum 11 mündet der Luftführungskanal 5'.An air mixing space 11 is arranged between the column 8a of the console 8 and the wall of the casing 1, in which the warm air outlet opening 3 is located. The air duct 5 'opens into the air mixing space 11.

Die Säule 8a,der Konsole 8 weist eine Öffnung 12 auf, die durch eine bimetallgesteuerte Klappe 13 verschließbar ist. Die Bimetallanordnung ist mit 14 bezeichnet.The column 8a, the console 8 has an opening 12 which can be closed by a bimetal-controlled flap 13. The bimetal arrangement is designated by 14.

An der Mündung des Luftführungskanals 5' in den Luftmischraum 11 ist ein Leitblech 15 angeordnet. Im Luftmischraum 11 ist ein Zusatzheizkörper 16 vorgesehen, der beispielsweise aus einem haarnadelförmig gebogenen Rohrheizkörper bestehen kann.At the mouth of the air duct 5 'in the air mixing space 11, a baffle 15 is arranged. An additional heating element 16 is provided in the air mixing space 11, which can consist, for example, of a tubular heating element bent in the shape of a hairpin.

Im Strahlungsbereich des Zusatzheizkörpers 16 ist ein Temperaturregler 17 angeordnet.A temperature controller 17 is arranged in the radiation region of the additional heating element 16.

Dem Temperaturregler 17 ist ein Hohlspiegel 18 zugeordnet. Die Anordnung ist so getroffen, daß der Temperaturregler 17 im Bereich der Brennweite des Hohlspiegels 18 liegt. Der Temperaturregler 17 liegt auch, nicht zuletzt durch das Luftleitblech 15, im Strömungsbereich der aus dem Luftführungskanal 5' und somit aus dem Speicherkern 4 kommenden Luft.A concave mirror 18 is assigned to the temperature controller 17. The arrangement is such that the temperature controller 17 is in the range of the focal length of the concave mirror 18. The temperature controller 17 is also, not least due to the air baffle 15, in the flow area of the air coming from the air duct 5 'and thus from the storage core 4.

Der Temperaturregler 17 ist zweckmäßig mit einem auf die höchstzulässige Temperatur der aus dem Speicherkern 4 kommenden Luft einstellbaren Kontakt und einem auf die höchstzulässige Temperatur des Zusatzheizkörpers 16 einstellbaren Kontakt ausgerüstet.The temperature controller 17 is expediently equipped with a contact which can be set to the maximum permissible temperature of the air coming from the storage core 4 and a contact which can be set to the maximum permissible temperature of the additional heating element 16.

Durch seine Anordnung und Ausbildung ist der Temperaturregler in der Lage, auf alle praktisch im Wärmespeicherheizgerät möglichen Störfälle anzusprechen, so zum Beispiel, wenn die Kaltluft-Einlaßöffnung verstopft ist und deshalb der den Speicherkern 4 durchströmenden Luft nicht genügend kühlere Luft beigemischt wird, wenn das Gebläse 1o ausgefallen oder die Klappe 13 in ihrer Verschlußlage blockiert ist und deshalb zu wenig Wärme vom Zusatzheizkörper 16 abgeführt wird oder wenn die Warmluft-Auslaßöffnung 3 verstellt oder verstopft ist. Auf Übertemperaturen des Zusatzheizkörpers 16 spricht der Temperaturregler 17 besonders schnell an, da durch den Hohlspiegel 18 Strahlungsschatten praktisch aufgehoben sind.Due to its arrangement and design, the temperature controller is able to respond to all faults practically possible in the heat storage heater, for example when the cold air inlet opening is clogged and therefore the cooler air flowing through the storage core 4 is not mixed with enough cooler air when the fan 1o failed or the flap 13 is blocked in its closed position and therefore too little heat is dissipated from the additional heating element 16 or if the warm air outlet opening 3 adjusts or ver is stuffed. The temperature controller 17 responds particularly quickly to excess temperatures of the additional heating element 16, since radiation shadows are practically eliminated by the concave mirror 18.
