Description
Anmelder: Fa. Noirot M.T. Paris/ Frankreich Titel: Heizelement für elektrische Heizkörper Beschreibung: Applicant: Fa. Noirot MT Paris / France Title: Heating element for electrical radiators Description:
Die Neuerung bezieht sich auf elektrische Heizkörper, deren Heizelemente aus rost-, gitter- oder gewebeförmig angeordneten Widerstandsdrähten zum Anschluß an einen elektrischen Stromkreis bestehen.The innovation relates to electric radiators, the heating elements of which are made of grate, grid or fabric There are resistance wires for connection to an electrical circuit.
Es ist bekannt (DE-GM 73 06 993), Heizelemente in V-Fonn mit spitzem Winkel auszubilden. Nun wurde aber erkannt, daß diese Form eines im Innern eines Heizkörperschachtes angeordneten Flächenheizelementes noch nicht einen optimalen Heißluftstrom, insbesondere in Bezug auf die Konvektionsgeschwindigkeit und die Gleichmäßigkeit der Luftmischung ergibt.It is known (DE-GM 73 06 993), heating elements in V-Fonn to be formed with an acute angle. But now it has been recognized that this form is arranged inside a radiator shaft Surface heating element does not yet have an optimal flow of hot air, especially with regard to the convection speed and gives the uniformity of the air mixture.
Daher liegt der Neuerung die Aufgabe zugrunde, das bekannte Heizelement in der Gestaltung seiner Heizfläche zu verbessern.Therefore, the object of the innovation is to improve the known heating element in the design of its heating surface.
Zur Lösung dieser Aufgabe ist neuerungsgemäß ein Heizelement für elektrische Heizkörper mit rost-, gitter- oder gewebeförmig angeordneten Widerstandsdrähten zum Anschluß an einen elektrischen Stromkreis und mit einer Einrichtung zum Befestigen am Heizkörperschacht dadurch gekennzeichnet, daß das aus mindestens einem Rost, Gitter oder Gewebe bestehende Heizelement in Bezug auf seine Vertikalachse symmetrisch und im Querschnitt bogenförmig gekrümmt ist. Vorteilhafterweise ist diese Krümmung ein Kreisbogen, der in Bezua auf die durch die beiden parallelen Befestigungsstäbe gehende Horizontalebene sowohl nach oben als auch nach unten gerichtet sein kann.To solve this problem, according to the invention, a heating element for electrical radiators with a grate, grid or fabric shape is provided arranged resistance wires for connection to an electrical circuit and with a device for fastening on the radiator shaft, characterized in that the consisting of at least one grate, grid or fabric Heating element is symmetrical with respect to its vertical axis and curved arcuately in cross section. Advantageously this curvature is an arc of a circle which, in Bezua, goes to the one passing through the two parallel fastening rods Horizontal plane can be directed both upwards and downwards.

Es können auch mehrere identische Heizelemente im gleichen Heizkörper vorgesehen sein, die auf verschiedene Weisen angeordnet sein können.A plurality of identical heating elements can also be provided in the same radiator, which are arranged in different ways could be.
Weitere Merkmale und Vorteile des neuerungsgemäßen Heizelementes sind der nachfolgenden Beschreibung von verschiedenen Ausführungsbeispielen, die in der Zeichnung in den Fig. 1 bis 5 schematisch und im Vertikalschnitt dargestellt sind, zu entnehmen.Further features and advantages of the heating element according to the invention are the following description of various Embodiments shown in the drawing in FIGS. 1 to 5 schematically and in vertical section are to be found.
Fig. 1 zeigt im Querschnitt ein auf bekannte Weise gewebtes Heizelement 1, das in einem Heizkörperschacht 2 angeordnet ist. Das Heizelement 1, im Schnitt, weist deutlich die Form einer Parabel auf und wird entlang seiner Längsränder von zwei Stäben 3 festgehalten, die in einer Horizontalebene parallel angeordnet sind; wobei die Krümmung des Heizelementes 1 nach unten gerichtet ist.1 shows in cross section a heating element 1 which is woven in a known manner and which is arranged in a radiator shaft 2. The heating element 1, in section, clearly has the shape of a parabola and is held along its longitudinal edges by two rods 3 which are arranged in parallel in a horizontal plane ; wherein the curvature of the heating element 1 is directed downwards.
Aufbau und Befestigung des Heizelementes sind bekannt. Sie sind nicht Gegenstand der Neuerung.The structure and attachment of the heating element are known. They are not the subject of innovation.
F Die Kaltluft durchströmt in Richtung des Pfeiles den Heizkörper und die Maschen des Heizelementes 1.F The cold air flows through the radiator and the mesh of the heating element 1 in the direction of the arrow.
Im Querschnitt kann das Heizelement gemäß der Fig. 1 auch Kreisbogenform aufweisen.In cross section, the heating element according to FIG. 1 can also have the shape of a circular arc.
Wir.d das Heizelement auf diese Weise gekrümmt, erhält man ein gleichmäßigeres Luftgemisch, wobei die Konvektionsgeschwindigkeit beibehalten wird. Dieser Vorteil konnte mit einem V-förmigen Heizelement wegen seines spitzen Winkels nicht in vollem Maße erreicht werden, obwohl die Bremsung der Konvektion leicht verringert werden kann, wenn der Winkel an der Spitze des Heizelementes größer als 60° und bis zu 120° erreichen kann und indem man das Heizelement umkehrt, d.h. so, daß esIf the heating element is curved in this way, a more even air mixture is obtained, whereby the convection speed is retained. This advantage could not be fully achieved with a V-shaped heating element because of its acute angle Dimensions can be achieved, although the braking of the convection can be reduced slightly if the angle is at the top of the heating element can be greater than 60 ° and up to 120 ° and by reversing the heating element, i.e. so that it

ein/I bildet. Die Krümmung des Heizelementes 1 kann, wie in Fig. 2 dargestellt, nach oben weisen.a / I forms. The curvature of the heating element 1 can, as in Fig. 2, point upwards.
Es können auch zwei identische nebeneinander angeordnete Heizelemente vorgesehen sein, wobei die Krümmung der beiden entweder nach unten (Fig. 3) oder nach oben (Fig. 4) zeigt.Two identical heating elements arranged next to one another can also be used be provided, the curvature of the two pointing either downwards (Fig. 3) or upwards (Fig. 4).
Auch drei identische Heizelemente 1 können- z,B, in versetzter Anordnung (Fig. 5) vorgesehen sein.Even three identical heating elements 1 can, for example, be offset Arrangement (Fig. 5) may be provided.
Schließlich sind auch noch andere Ausführungsformen, auch in der Anzahl und Anordnung der Heizelemente im Rahmen der Neuerung möglich.Finally, other embodiments are also possible, also in FIG the number and arrangement of the heating elements possible within the scope of the innovation.
