Abstract
Description
Die vorliegende Erfindung betrifft eine Luftausströmeinrichtung für Fahrzeugklimaanlagen gemäß dem Oberbegriff des Patentanspruches 1.The The present invention relates to an air exhaust device for vehicle air conditioners according to the generic term of claim 1.
Die meisten modernen PKW weisen im Bereich der Instrumententafel mehrere Luftausströmeinrichtungen auf, die auch als "Grills" bezeichnet werden. Die Luftausströmgrills sind üblicherweise durch mehrere parallel angeordnete verstellbare waagrechte Luftleitlamellen und durch mehrere quer dazu angeordnete verstellbare vertikale Luftleitlamellen gebildet. Die in den Fahrgastraum einströmende Luft kann durch entsprechende Einstellung der Horizontal- bzw. Vertikallamellen in die gewünschte Richtung gelenkt werden. Wenn die in den Fahrgastraum strömende Luft sehr stark umgelenkt werden soll, müssen die Lamellen so eingestellt werden, dass sie einen erheblichen Strömungswiderstand darstellen. Um auch für derartige Einstellungen einen hinreichenden Luftstrom zu ermöglichen, muss das Gebläse der Fahrzeugklimaanlage entsprechend stark ausgelegt sein. Durch den starken Strömungswiderstand der Luftleitlamellen ergibt sich bei starker Luftumlenkung ein entsprechend hoher Strömungsgeräuschpegel.The Most modern cars have several in the area of the instrument panel Luftausströmeinrichtungen which are also known as "grills". The air out grills are usually by several parallel adjustable horizontal air deflectors and by a plurality of transversely arranged adjustable vertical vanes educated. The incoming air into the passenger compartment can by appropriate Adjustment of the horizontal or vertical slats in the desired direction be steered. When the air flowing into the passenger compartment is very much diverted should be, must The fins are adjusted so that they have a significant flow resistance represent. In order for too such settings allow a sufficient flow of air must the blower the vehicle air conditioning to be designed accordingly strong. By the strong flow resistance the louvers results in strong air deflection a corresponding high flow noise level.
Um mit herkömmlichen Luftauslassgrills eine starke Umlenkung der ausströmenden Luft zu ermöglichen, müssen die Grills relativ groß konzipiert sein. Je nach Gestaltung der Instrumententafel kann es sein, dass die Ebene, in der die Luftauslassgrills angeordnet sind, relativ stark geneigt ist, was dazu führt, dass bestimmte Luftausströmrichtungen nicht darstellbar sind.Around with conventional Air outlet grilles a strong deflection of the outflowing air to enable have to the grills are designed to be relatively large. Depending on the design of the instrument panel, it may be that the Level in which the Luftauslassgrills are arranged relatively strong inclined, which leads to that certain Luftausströmrichtungen can not be displayed.
Mit herkömmlichen Luftauslassgrills ist es auch schwierig, eine stark konzentrierte Luftausströmung, einen sogenannten "Spot" darzustellen. Schwierig darzustellen ist auch eine diffuse Luftausströmung.With usual Air outlet grills, it is also difficult, a highly concentrated air outflow, to represent a so-called "spot". Difficult is also a diffuse air outflow.
Aufgabe der Erfindung ist es, eine Luftausströmeinrichtung für Fahrzeugklimaanlagen zu schaffen, bei der die Luftumlenkung nicht auf herkömmlichen Luftleitelementen basiert und die dennoch eine hohe Variabilität bietet, was die Verteilung der in den Fahrgastraum ausströmenden Luft anbelangt.task The invention is an air exhaust device for vehicle air conditioners to create, in which the air deflection not on conventional Air guiding elements based and yet offers a high variability, what the distribution of air flowing into the passenger compartment As.
Diese Aufgabe wird durch die Merkmale des Patentanspruches 1 gelöst. Vorteilhafte Ausgestaltungen und Weiterbildungen der Erfindung sind den Unteransprüchen zu entnehmen.These The object is solved by the features of claim 1. advantageous Refinements and developments of the invention are the dependent claims remove.
Ausgangspunkt der Erfindung ist eine Luftausströmeinrichtung für Fahrzeugklimaanlagen mit einem Luftkanal, in dem eine Luftströmung erzeugbar ist, und einer Luftaustrittsöffnung, über die Luft aus dem Luftkanal in einen Fahrgastraum eines Fahrzeugs strömen kann.starting point The invention is a Luftausströmeinrichtung for vehicle air conditioning with an air duct in which an air flow can be generated, and one Air outlet opening, over the Air from the air duct in a passenger compartment of a vehicle can flow.
Das Grundprinzip der Erfindung besteht darin, zur Umlenkung der in den Fahrgastraum strömenden Luft anstatt herkömmlicher lamellenartiger Luftleitelemente den aus der Strömungsmechanik bekannten Magnus-Effekt zu nutzen. Unter dem Magnus-Effekt versteht man die Tatsache, dass ein luftumströmter rotierender Körper die anströmende Luft in Abhängigkeit von seiner Drehrichtung und seiner Drehgeschwindigkeit quer zur Richtung der anströmenden Luft ablenkt.The Basic principle of the invention is to deflect the in the Passenger space pouring Air instead of conventional lamellar spoilers known from the fluid mechanics Magnus effect to use. The Magnus effect is the fact that an airflow rotating body the incoming air dependent on from its direction of rotation and its rotational speed across Direction of the oncoming Air distracts.
Gemäß der Erfindung wird vorgeschlagen, im Bereich der Luftaustrittsöffnung mindestens ein luftumströmtes rotierbares Element anzuordnen, durch das die in den Fahrgastraum ausströmende Luft in Abhängigkeit von der Drehrichtung und der Drehgeschwindigkeit dieses Element abgelenkt wird. Bei dem rotierbaren Element kann es sich beispielsweise um ein walzenartiges Element handeln. Insbesondere können zwei oder mehrere solcher Elemente nebeneinander angeordnet werden.According to the invention is proposed, in the region of the air outlet opening at least one air-flow rotatable Element to arrange, through which the air flowing out into the passenger compartment dependent on from the direction of rotation and the rotational speed of this element is distracted. The rotatable element may be, for example to act a roller-like element. In particular, two or several such elements are arranged side by side.
Nach einer Weiterbildung der Erfindung ist eine Antriebseinrichtung vorgesehen, mit der das rotierbare Element angetrieben werden kann. Hierbei kann es sich beispielsweise um einen Elektromotor handeln. Vorzugsweise ist eine Steuereinrichtung, insbesondere eine Elektronik vorgesehen, mit der die Drehfrequenz und/oder die Drehrichtung mit bzw. in der die Antriebseinrichtung das rotierbare Element antreibt, verstellt werden kann.To A development of the invention provides a drive device, with which the rotatable element can be driven. Here can it may for example be an electric motor. Preferably is a control device, in particular an electronics provided, with the rotational frequency and / or the direction of rotation with or in the the drive device drives the rotatable element, adjusted can be.
Das rotierbare Element kann eine im Wesentlichen glatte Oberfläche oder eine rauhe bzw. strukturierte Oberfläche mit einer Vielzahl von Erhebungen bzw. Vertiefungen, z. B. ähnlich wie die Oberfläche eines Golfballs, aufweisen.The rotatable element can be a substantially smooth surface or a rough or textured surface with a variety of Elevations or depressions, z. B. similar to the surface of a Golf balls.
Im Folgenden wird die Erfindung im Zusammenhang mit der Zeichnung näher erläutert. Es zeigen:in the The invention will be explained in more detail in connection with the drawing. It demonstrate:
