Description

Gegenstand der Erfindung ist die weitere Ausgestaltung des einen elektrischen Heizkörper enthaltenden Heizlüfters nach Patent 8t;6 oo6. Sie betrifft eine Maßnahme, die das Gerät für die Anwendung höherer Heizleistungen von beispielsweise a bis 3 kW geeignet macht, wobei die Ab- messungen des Gerätes relativ klein gehalten werden können.The subject of the invention is the further embodiment of the fan heater containing an electric radiator according to patent 8t; 6 oo6. It relates to a measure that makes the device for the use of higher heating capacities, for example, a 3 kW suitable, the exhaust measurements of the device can be kept relatively small.

Bei einer- solchen Heizleistung, mit der eine gewünschte Raumtemperatur in kurzer Zeit erreicht werden kann, ist ein automatischer Schalter erforderlich, der die Innehaltung einer eingestellten Raumtemperatur ohne unbequemes Ein- und Ausschalten von Hand ermöglicht. Erfindungsgemäß wird der temperaturabhängige Schalter an der L ufteintrittsseite des Heizkörpers an einer Stelle angebracht, wo bei normal laufender Luftschraübe die Temperatur des Fühlers vorwiegend' von der einströmenden Luft bestimmt wird, während bei behinderter Luftströmung, die wegen ungenügender Wärmeabfuhr eine das Gerät gefährdende Erwärmung nach sich zöge, die Strahlung des Heizkörpers den Fühler erwärmt und dessen Abschaltung bewirkt, bevor das Gerät Schaden nehmen ],arm.With such a heating output that a desired room temperature can be reached in a short time, an automatic switch is required, that allows you to maintain a set room temperature without uncomfortable entry and exit Switching off by hand possible. According to the invention, the temperature-dependent switch on the air inlet side of the radiator at a point where at normal The temperature of the sensor is predominantly different from that of the incoming air flow Air is determined, while with obstructed air flow, which is due to insufficient Heat dissipation would result in warming that would endanger the device, the radiation of the Radiator heats the sensor and causes it to switch off before the device is damaged take], poor.

In der Zeichnung ist ein Ausführungsbeispiel der Erfindung; dargestellt. Auf einen Fuß r ist das äußere Gehäuse a mit dem Schutzgitter 3 dargestellt, 4 bedeutet einen elektrischen Heizkörper, dessen Befestigungsstellen am Gehäuse hinter dem Strahlschutz j angreifen. Der Motor 6 ist von einem Schutzrohr j umgehen, das nahe der Luftschraube S trichterförmig erweitert ist. Der temperaturabhängige Schalter ist an der Stelle g angeordnet, wo er von der eintretenden Luft unnspiilt wird hzw. unter der verstärkten Strahlung des Heizkörpers anspricht, sobald der Luftstrom aussetzt.In the drawing is an embodiment of the invention; shown. On a foot r, the outer housing a is shown with the protective grille 3, 4 means an electric heater, the fastening points of which on the housing behind the Attack radiation protection j. The motor 6 is bypassed by a protective tube j, which is close the propeller S is expanded in a funnel shape. The temperature-dependent switch is arranged at the point g, where it is not flushed by the incoming air hzw. under the increased radiation of the radiator responds as soon as the air flow suspends.
