Die Neuerung bezieht sich auf ein elektrisches Eaiiiahoizgerät mit einem Gebläse, vorzugsweise einem Querstromgebläse tma einem ifi Blasstrom des Gebläses angeordneten Hei-zwiäerstancLThe innovation relates to an electrical electrical appliance with a fan, preferably a cross-flow fan and a heating intermediate arranged in a blower stream of the fan
Bei derartigen Geräten treten gelegentlich Schaden am laufrad des Gebläses infolge Überhitzung auf, die auf direkte Warnestrahlung des Heizwiders'tandes zurückzuführen sind.Such devices occasionally damage the impeller of the Fan due to overheating, which reacts to direct warning radiation of the heating resistance.
Aufgabe der Neuerung iot es, derartige Schäden auszuschließen, ohne· die Abmessungen des Gerätes zu vergrößern.The task of the innovation is to exclude such damage, without · increasing the dimensions of the device.
Neuerungsgemäß wird diese Aufgabe dadurch gelöst, daß zwischen dem Gebläse und dem Heizwiderstand eine Strahlungsblende schräg zur Strömungsrichtung verlaufend derart angeordnet ist, daß sie das Gebläselaufrad gegen die direkte Wärmestrahlung des Heizwiderstandes abschirmt.According to the innovation, this object is achieved in that between the Fan and the heating resistor a radiation diaphragm is arranged obliquely to the flow direction so that it Shields the fan impeller against direct heat radiation from the heating resistor.

Bei der Verwendung eines Querstromgebläses kann eine derartige Blende gleichzeitig als ein die Strömungsverhältnisse begünstigedes Luftleitbieeh ausgebildet sein.When using a cross-flow fan, such a diaphragm can at the same time favor the flow conditions Be formed Luftleitbieeh.
Besonders vorteilhaft ist es, wenn der Heizwiderstand und die Blende in einem Luftführungskanal angeordnet sind, dessen Strömungsquerschnitt im Bereich des Heizwiderstandes eingeengt ist, so daß die vom Gebläse geförderte Luft zwangsweise in den Wirkungsbereich des Heizwiderstandes gelangt- Dadurch wird verhindert., daß Teile der vom Gebläse geförderten Luft nur mangelhaft erwärmt aus dem Gerät austreten..It is particularly advantageous if the heating resistor and the diaphragm are arranged in an air duct, the flow cross-section of which is narrowed in the area of the heating resistor, so that the air conveyed by the fan is forced into the area of action of the heating resistor - this prevents parts of the air conveyed by the blower does not leave the device warmed enough.

In einem Gehäuse 1, das Ansaugschlitze 2 und Luftaustrittsschlitze 3 aufweist, die über einen Luftführungskanal 4 miteinander verbunden sind, ist im Bereich der Ansaugschlitze 2 ein Querstromgebläse 5 und im Strömungsquerschnitt des Luftführungskanals 4 ein Heizwiderstand 6 angeordnet. Zwischen dem Gebläse 5 und dem Heizwiderstand 6 ist eine Blende 7 schräg in den Strömungsweg der vom Gebläse 5 geförderten Luft so eingelegt, daß das Gebläse I gegen direkte Wärmestrahlung des Heizkörpers 6 abgeschirmt ist. Die Blende 7 dient gleichzeitig als Luftleitblech zur Verbesserung der Strömungsverhältnisse im Luftleitkanal 4.In a housing 1, which has suction slots 2 and air outlet slots 3, which are connected to one another via an air duct 4, a cross-flow fan 5 is arranged in the area of the suction slots 2 and a heating resistor 6 is arranged in the flow cross-section of the air duct 4. Between the fan 5 and the heating resistor 6, a diaphragm 7 is inserted obliquely into the flow path of the air conveyed by the fan 5 in such a way that the fan I is shielded from direct heat radiation from the heater 6. The screen 7 also serves as an air guide plate to improve the flow conditions in the air guide channel 4.
