Description

Lüfter, insbesondere mit elektromotorischem .Antrieb In dem Patent 883 797 ist die Verbesserung eines insbesondere mit elektromotorischem Antrieb versehenen Lüfters dargestellt und beschrieben, wonach der Lüfter mit einer selbsttätig arbeitenden Vorrichtung versehen ist, welche die Drehzahl des Lüfterflügels periodisch abfallen und wieider ansteigen läßt. Mittels einer solchen Vorrichtung wird erreicht, daß von denn Lüfter nicht eindauernd gleichmäßig fließender, sondern absatzw@ise unterbrochener Luftstrom entsteht, wodurch die sonst auftretenden unerwünschten Zugerscheinungen sicher vermieden werden.. Im folgenlden wind nun ein Mittel gezeigt, durch, das jeder bereits schon vorhandene Lüfter so eingerichtet werden kann, daß er in der gleichen Weise keinen ständig fließenden Luftstrom gleicher Stärke erzeugt, sondern in gewissen periodischen Zeitabstähden angenehm wirkende Luftstöße hervorruft.Fan, in particular with an electromotive drive. Patent 883 797 shows and describes the improvement of a fan provided in particular with an electromotive drive, according to which the fan is provided with an automatically operating device which periodically decreases the speed of the fan blade and increases it again. By means of such a device it is achieved that the fan does not continuously flow evenly, but absatzw @ ise interrupted air flow, whereby the otherwise occurring undesirable drafts are safely avoided Fan can be set up in such a way that it does not generate a constantly flowing air stream of the same strength in the same way, but rather generates pleasant blasts of air at certain periodic intervals.

Gemäß der Erfindung ist zu diesem Zweck die das periodische Abfallen und Wiederansteigen der Drehzahl des Lüfterflügels bewirkende Vorrichtung als Zusatzgerät ausgebildet, das in,die Stromzuführungsleitung eines bereits vorhandenen Lüfters einfügbar ist. Man kann dann eine solche Hilfsvorrichtung auch nachträglich bei .bereits vorhandenen Lüfteranl.agen ohne weiteres vorsehen, ohne daß hierbei besondere Änderungen der Lüfteranlage erforderlich sind. Zweckmäßig ist die Hilfsvorrichtung so ausgebildet, daß sie m'it der Netzsteckdose verbindbar ist, während sie selbst als Steckdose ausgebildet ist, in welche der am Ende der Stromzuführungsleitung des Lüfters befindliche Stecker ein,s.teckbar ist.According to the invention, this is the periodic decay for this purpose and an increase in the speed of the fan blade causing device as an additional device formed in, the power supply line of an existing fan is insertable. You can then do one Auxiliary device can also be retrofitted for existing fan systems without further ado, without doing this special changes to the fan system are required. The auxiliary device is useful designed in such a way that it can be connected to the mains socket while it is itself is designed as a socket into which the at the end of the power supply line plug located in the fan, see can be plugged in.
