摘要： Bei einem Axiallüfter (1), der um eine senkrechte Achse schwenkbar gelagert ist und ein parallel zu dieser angeordnetes in den Luftstrom ragendes Ruderblatt (11) aufweist, das an der dem Lüfterrad (3) zugekehrten Seite verstellbar gehalten ist, ist das Ruderblatt (11) in Strömungsrichtung des Luftstromes (A) ein- oder mehrfach nach einer Seite abgekröpft (Abkentung 15) oder seitlich abgebogen ausgebildet. Außerdem ist zur Umlenkung des Luftstromes (A) nach oben oder unten eine vorzugsweise achssenkrecht zu dem Ruderblatt (11) und mittig angeordnete Steuerklappe (21) vorgesehen, die zur Einstellung der Drehgeschwindigkeit des Axiallüfters (1) mit einer Freisparung, mit Einschnitten od. dgl. versehen ist, in die das Ruderblatt (11) eingreift.
Durch diese Ausgestaltung wird erreicht, daß stets ein ausreichendes Moment erzeugt wird, durch das der Lüfter (1) in Rotation gesetzt wird. Der die Abkröpfung beaufschlagende Luftstrom bewirkt dies in zuverläßiger Weise. Und durch Schrägstellen des Ruderblattes (11) kann die Drehgeschwindigkeit problemlos erhöht werden, wobei ausgehend von einer Minimaldrehzahl, die bei achssenkrechter Stellung des Ruderblattes (11) und somit nur bei einer Beaufschlagung der Abkröpfung erzeugt wird, auch eine feinfühlige Drehzahlregelung möglich ist.
Des weiteren ist die Baulänge des vor allem zum Trocknen von keramischen Formlingen in vorteilhafter Weise verwendbaren Lüfters (1) kurz und der Drehkreisdurchmesser ist klein. Ferner ist ausgeschlossen, dass die Rotationsgeschwindigkeit zu stark ansteigt. Das in der Steuerklappe geführte Ruderblatt ist nämlich nur in Grenzen verstellbar, so dass Fehleinstellungen nicht möglich sind.

摘要： A ceiling fan includes at least one rotary shaft (10) that has a seat (11) being semi-circular and a guiding portion (12) being semi-spherical and having a guiding surface (121). A lower sealing ring (50) of the ceiling fan has at least one protrusion (52). The guiding portion (12) is mounted through the lower sealing ring (50) and the guiding surface (121) abuts against the at least one protrusion (52). With the semi-circular seat (11) and the semi-spherical guiding portion (12), when the rotary shaft (10) is rotated, the guiding surface (121) and the at least one protrusion (52) coordinate with each other to rotate. The rotary shaft (10) has reduced volume. Accordingly, the ceiling fan having the rotary shaft (10) is lightweight, has reduced power consumption and manufacturing cost, and is easy for installation.

摘要： A rotation driving mechanism (3) of an air supply apparatus, an air supply apparatus (10), and a household appliance (100). The rotation driving mechanism (3) of the air supply apparatus comprises: a fixed bracket (31); a rotary bracket (32), wherein the rotary bracket (32) is sleeved on the fixed bracket (31) and may rotate with respect to the fixed bracket (31); and a driving member (41), wherein the driving member (41) is provided on the fixed bracket (31) and used for driving the rotary bracket (32) to rotate. Therefore, compared with the prior art, by means of the coordination of the fixed bracket (31), the rotary bracket (32), and the driving member (41), the size of the rotation driving mechanism (3) can be reduced; after the rotation driving mechanism (3) is mounted on the air supply apparatus (10), the air supply apparatus (10) can have a better appearance; moreover, the rotation angle of the rotary bracket (32) with respect to the fixed bracket (31) is not limited, and thus, the shaking angle of the rotary component of the air supply apparatus (10) can be enlarged.
