Description

Lüfter mit Außenläufermotor Gegenstand der Erfindung ist ein Lüfter bzw. Ventilator, der für L uftumwälzungs-, Luftheizungs-, Klimaanlagen od. dgl. Verwendung finden soll. Als Antriebsmittel ist ein an sich bekannter Außenläufermotor vorgesehen.Fan with external rotor motor The invention relates to a fan or fan that is used for air circulation, air heating, air conditioning systems or the like. Should be used. A known external rotor motor is used as the drive means intended.

Ventilatoren u. dgl., bei denen ein Außenläufermotor als Antriebsmittel Verwendung findet, sind bekannt. Hier sind dann an den umlaufenden Gehäusen die Flügel anmontiert. Das Befestigen erfolgt mittels Schrauben, Haltungen od. dgl. Bei einer weiteren bekannten Ausführungsform sind die Flügel auch in schwalbenschwanzförmig ausgebildeten Nuten eingelassen; zur Sicherung müssen Arretierungsmittel vorgesehen sein.Fans and the like, in which an external rotor motor is used as the drive means Is used are known. These are then on the circumferential housings Wing mounted. The fastening is done by means of screws, postures or the like. In a further known embodiment, the wings are also dovetail-shaped formed grooves embedded; locking means must be provided for securing be.

Diese bekannten Ventilatoren bzw. Deckenfächer haben jedoch den Nachteil, daß die entsprechenden Gehäuseoberflächen und diezugeordnetenBefestigungsflächen der Flügel zunächst - als Montagevorbereitung - bearbeitet werden müssen. Damit ist ein erheblicher Arbeitsaufwand verbunden. Die Haltemittel stören die Formschönheit, und es bedarf Auswuchtzeiten. Ein weiterer Nachteil ist darin zu sehen, daß der Wärmefluß nicht so günstig ist wie bei der neuen Ausführungsform.However, these known fans or ceiling fans have the disadvantage that the corresponding housing surfaces and the associated mounting surfaces the wing must first be processed - as preparation for assembly. In order to a considerable amount of work is involved. The holding means disrupt the aesthetics, and balancing times are required. Another disadvantage is that the Heat flow is not as favorable as in the new embodiment.

Den geschilderten Nachteilen begegnet die Erfindung dadurch, daß Flügel und Außengehäuse des Außenläufermotores ein Werkstück bilden. Damit ist es möglich, formschöne und gut ausgewuchtete Ventilatoren billig herzustellen.The invention counteracts the disadvantages outlined by the fact that wings and the outer housing of the external rotor motor form a workpiece. This makes it possible Shapely and well-balanced fans can be produced cheaply.

Eine besondere Ausführungsform ist darin zu sehen, daß das Verhältnis Motorlänge zu Flügelradaußendurchmesser etwa 1 : 1 ist. Diese Bauform trägt der Forderung Rechnung, daß die Luftumwälzung durch kleinstmögliche Geräte erfolgen soll.A special embodiment can be seen in the fact that the ratio Motor length to impeller outer diameter is approximately 1: 1. The Requirement calculation that the air circulation take place through the smallest possible devices target.

Weitere Einzelheiten der Erfindung ergeben sich aus der Zeichnung und der Beschreibung.Further details of the invention emerge from the drawing and the description.

Wie aus Fig. 1 ersichtlich, sind die Flügel I an das Außengehäuse 2 des Außenläufermotors 3 unmittelbar angegossen. In gleicher Weise bestehen das Gehäuse 4 und der Läufer 5 gemäß Fig. 2 aus einem Stück.As can be seen from Fig. 1, the wings I are attached to the outer housing 2 of the external rotor motor 3 is cast directly on. In the same way, they exist Housing 4 and the rotor 5 according to FIG. 2 in one piece.

Es ergibt sich damit jeweils eine Baueinheit, weil alle Flügel an den Gehäuse des Außenläufermotors angegossen worden sind.This results in a structural unit, because all the wings are on the housing of the external rotor motor have been cast.
