Description

Die Erfindung betrifft einen Lüfter insbesondere Deckenlüfter mit einem Gehäuse, an dessen Unter- und/oder Oberseite Luft eintritt und an dessen übrigen Seiten Luft austritt.The invention relates to a fan, in particular ceiling fan with a housing, air enters at the bottom and / or top and air exits from the other sides.

Es ist bekannt, die Unterseite eines Deckenlüfters flach zu gestalten, wobei die Unterseite vom Gehäuseboden gebildet ist. In den Fällen, in denen der Lüfter an der Unterseite die Luft ansaugt, ist die Ansaugöffnung deutlich sichtbar. Die seitlichen Austrittsöffnungen des Lüfters besitzen oft Lamellen, die an der Außenseite vorstehen, wenn sie stirnseitig Luft ansaugen sollen. Diese Lamellen können durch ein seitliches Anstoßen leicht beschädigt werden.It is known to make the underside of a ceiling fan flat, the underside being formed by the housing base. In the cases where the fan sucks in the air on the underside, the suction opening is clearly visible. The side outlet openings of the fan often have fins that protrude on the outside when they are supposed to suck in air on the front. These slats can easily be damaged by knocking on the side.

Aufgabe der Erfindung ist es, einen Lüfter der eingangs genannten Art so zu verbessern, daß bei einfacher Konstruktion die Gehäuseunterseite nicht sichtbar und die Gehäuseaußenseiten gegen Beschädigungen geschützt sind.The object of the invention is to improve a fan of the type mentioned in such a way that, with a simple construction, the underside of the housing is not visible and the outside of the housing is protected against damage.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die Unterseite des Lüfters durch eine flache Abdeckung abgedeckt ist, die mit ihren Rändern über die Außenabmessungen des Lüftergehäuses vorsteht.This object is achieved in that the underside of the fan is covered by a flat cover which protrudes with its edges over the outer dimensions of the fan housing.

Eine solche flache insbesondere gekrümmte Abdeckung verdeckt die Unterseite des Lüfters, insbesondere dessen Ansaugöffnung, so daß die Gehäuseunterseite wenig aufwendig gestaltet werden muß. Die Gehäuseunterseite bleibt unsichtbar, so daß nach einiger Zeit auftretende Verschmutzungen der Ansaugöffnung nicht sichtbar werden. Ferner können die vorstehenden Außenränder der Abdeckung Stöße abfangen, so daß die Lamellen der Luftauslässe geschützt sind.Such a flat, in particular curved cover covers the underside of the fan, in particular its suction opening, so that the underside of the housing has to be designed with little effort. The underside of the housing remains invisible, so that after a while any dirt on the intake opening does not become visible. Furthermore, the protruding outer edges of the cover can absorb impacts, so that the lamellae of the air outlets are protected.

Besonders vorteilhaft ist es, wenn die Abdeckung außenseitig konvex gekrümmt ist. Hierbei kann die Abdeckung in einem Abstand zur Gehäuseunterseite so befestigt sein, daß ein flacher Zwischenraum zwischen Gehäuse und Abdeckung besteht.It when the cover is convexly curved on the outside is particularly advantageous. Here, the cover can be attached at a distance from the underside of the housing so that there is a flat space between the housing and the cover.

Besonders vorteilhaft ist es, wenn die Abdeckung einen Kegel- oder Zylinderabschnitt bildet. Auch sollte die Abdeckung zahlreiche Luftdurchtrittsöffnungen aufweisen.It is particularly advantageous if the cover forms a cone or cylinder section. The cover should also have numerous air passage openings.

Vorzugsweise wird vorgeschlagen, daß die Abdeckung von einer Scheibe oder Platte aus Metall, Kunststoff oder Glas gebildet ist. Auch ist von Vorteil, wenn die Ecken der Abdeckung abgerundet sind.It is preferably proposed that the cover be formed by a disk or plate made of metal, plastic or glass. It is also an advantage if the corners of the cover are rounded.

Besonders vorteilhaft ist es, wenn zwischen der Abdeckung und der Gehäuseunterseite ein Filter vor der Ansaugöffnung befestigt ist. Auch sollte die Abdeckung waagerecht angeordnet sein.It is particularly advantageous if a filter is attached in front of the suction opening between the cover and the underside of the housing. The cover should also be arranged horizontally.

Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt und wird im folgenden näher beschrieben. Es zeigen:

Figur 1:
Eine Draufsicht von oben auf einen Deckenlüfter bei abgenommenem oberen Deckblech und
Figur 2:
einen senkrechten Schnitt durch den Lüfter nach II- II in Figur 1.
An embodiment of the invention is shown in the drawing and will be described in more detail below. Show it:
Figure 1:
A top view of a ceiling fan with the top cover and removed
Figure 2:
a vertical section through the fan according to II-II in Figure 1.

Der Lüfter insbesondere als Deckenlüfter weist einen Lüfterinnenraum 1 auf, in dem ein von einem Elektromotor 2 angetriebenes Lüfterrad 3 befestigt ist. Bei einer Montage des Lüfters an der Decke eines Raumes ist die Achse des Elektromotors und des Lüfterrades senkrecht und der Lüfterinnenraum 1 weist eine größere Breite als Höhe auf.The fan, in particular as a ceiling fan, has a fan interior 1 in which a fan wheel 3 driven by an electric motor 2 is fastened. When the fan is mounted on the ceiling of a room, the axis of the electric motor and the fan wheel are vertical and the fan interior 1 has a greater width than height.

Das Lüfterrad saugt im Ausführungsbeispiel über eine untere Ansaugöffnung 4 die Luft in den Lüfterinnenraum 1 an, wobei Lüfterrad 3 und Elektromotor 2 von einem gekrümmten Wärmetauscher 5 ringsum umgeben sind, der zahlreiche Rohre 6 aufweist, die aneinander angeschlossen sind und zu Anschlußstutzen 7, 8 führen. Die Ansaugöffnung 4 kann auch an der Oberseite 4 des Lüftergehäuses angeordnet sein, wenn der Lüfter an einer Zwischendecke und/oder an einem Luftkanal unterseitig befestigt ist.In the exemplary embodiment, the fan wheel sucks the air into the fan interior 1 via a lower suction opening 4, the fan wheel 3 and electric motor 2 being surrounded all around by a curved heat exchanger 5 which has numerous tubes 6 which are connected to one another and lead to connecting pieces 7, 8 . The suction opening 4 can also be arranged on the upper side 4 of the fan housing if the fan is fastened on the underside to an intermediate ceiling and / or to an air duct.

Die Ansaugöffnung 4 ist durch ein auswechselbares Filter 9 überdeckt. Ferner ist an der Unterseite des Lüftergehäuses eine untere flache Abdeckung in gekrümmter Form befestigt, die das Lüftergehäuse zu allen Seiten überragt.The suction opening 4 is covered by an exchangeable filter 9. Furthermore, a lower flat cover in a curved shape is attached to the underside of the fan housing, which projects beyond the fan housing on all sides.

Das Lüftergehäuse besitzt auf allen vier Seiten jeweils einen Luftauslaß 11 und dazwischenliegende Eckbereiche 12. Diese Eckbereiche 12 sind als Teilzylinder in Viertelkreisform gekrümmt und enden jeweils an einem Luftauslaß 11.The fan housing has an air outlet 11 on all four sides and corner areas 12 located between them. These corner areas 12 are curved as partial cylinders in a quarter-circle shape and each end at an air outlet 11.

In jedem Luftauslaß 11 befinden sich waagerechte Lamellenpaare 13, die die austretende Luft leiten. Die zwei Lamellen eines Lamellenpaares 13 bilden zwischen sich einen Zwischenraum 14, der zu beiden Stirnseiten offen ist, um dort seitlich Luft ansaugen zu können.In each air outlet 11 there are horizontal pairs of lamellae 13 which guide the escaping air. The two fins of a pair of fins 13 form an intermediate space 14 between them which is open on both end faces in order to be able to suck in air laterally there.

Die offenen Stirnseiten 15 der Lamellenpaare 13 sind durch eine Seitenwand 16 bedeckt, die Luftdurchtrittsöffnungen 17 in Form von waagerechten Langlöchern aufweist. Die Seitenwandöffnungen können auch sehr klein und insbesondere siebförmig sein. In einer alternativen Bauform fehlt die Seitenwand 16 und die Luft strömt von einem seitlichen Raum 20 ungehindert zu den Lamellenzwischenräumen 14.The open end faces 15 of the pairs of fins 13 are covered by a side wall 16 which has air passage openings 17 in the form of horizontal elongated holes. The side wall openings can also be very small and in particular sieve-shaped. In an alternative design, the side wall 16 is missing and the air flows unhindered from a lateral space 20 to the lamella intermediate spaces 14.

Zwischen den Stirnseiten 15 und der Seitenwand 16 besteht ein schmaler, spaltförmiger, senkrechter Zwischenraum 18, in dem ein Gestänge angeordnet sein kann, durch das die Lamellenpaare um eine Drehachse 19 schwenkverstellbar sind.Between the end faces 15 and the side wall 16 there is a narrow, gap-shaped, vertical space 18 in which a linkage can be arranged, through which the pairs of lamellae can be pivoted about an axis of rotation 19.

Der Eckbereich 12 bildet in seinem Inneren einen Luftzuführungsraum (Eckraum) 20, der den Bereich zwischen zwei Luftauslässen 11 ausfüllt und zu den zwei Luftauslässen 11 hin bzw. zu den Lamellenpaaren hin jeweils durch die luftdurchlässige Seitenwand 16 begrenzt ist. Ferner ist der Luftzuführungsraum (Eckraum) 20 nach außen durch eine äußere gekrümmte Abdeckwand 21 begrenzt, die als Eckabdeckung dient. Die Abdeckwand 21 weist zahlreiche Luftdurchtrittsöffnungen auf, und kann auch siebförmig gestaltet sein. Die Abdeckwand 21 ist im Ausführungsbeispiel einstückig mit den zwei Seitenwänden 16 ausgebildet, so daß die Abdeckwand zu ihren beiden Seiten in den Seitenwänden 16 endet, die gegenüber der Wand 21 rechtwinklig nach innen abgebogen sind. Zur Innenseite hin ist der Luftzuführungsraum 20 durch eine luftundurchlässige Innenwand 22 begrenzt, die derart schräg angeordnet ist, daß sie einen Winkel von 45 Grad mit der Ebene der Luftauslässe 11 bildet. Bei einer Montage des Lüfters an einer Deckenunterseite stehen die Wände 16, 21 und 22 senkrecht.The corner area 12 forms in its interior an air supply space (corner space) 20 which fills the area between two air outlets 11 and is delimited by the air-permeable side wall 16 towards the two air outlets 11 or towards the pairs of slats. Furthermore, the air supply space (corner space) 20 is limited on the outside by an outer curved cover wall 21, which serves as a corner cover. The cover wall 21 has numerous air passage openings, and can also be sieve-shaped. In the exemplary embodiment, the cover wall 21 is formed in one piece with the two side walls 16, so that the cover wall ends on both sides in the side walls 16 which are bent inwards at right angles with respect to the wall 21. To the inside, the air supply space 20 is delimited by an air-impermeable inner wall 22 which is arranged obliquely in such a way that it forms an angle of 45 degrees with the plane of the air outlets 11. When the fan is mounted on an underside of the ceiling, the walls 16, 21 and 22 are vertical.

Die in die Stirnseiten 15 der Lamellenzwischenräume 14 eintretende Luft wird durch die Öffnungen der Seitenwand 16 aus dem Raum 20 angesaugt, wobei die Luft in den Raum 20 durch die Abdeckwand 21 nachströmt. Darüberhinaus kann der Raum 20 Luft durch seine Ober- und/oder Unterseite erhalten, wenn diese offen gestaltet sind. Im Ausführungsbeispiel endet die Seitenwand 16 vor dem oberen Deckblech 23, so daß von oben Luft in den Raum 20 nachströmen kann. Ferner kann die Unterseite des Raums 20 durch einen gelochten Boden 24 verschlossen sein, so daß auch von der Unterseite des Gerätes her Luft in den Raum 20 strömen kann.The air entering the end faces 15 of the lamella intermediate spaces 14 is sucked out of the space 20 through the openings in the side wall 16, the air flowing into the space 20 through the cover wall 21. In addition, the room 20 can receive air through its top and / or bottom if these are designed to be open. In the exemplary embodiment, the side wall 16 ends in front of the upper cover plate 23, so that air can flow into the space 20 from above. Furthermore, the underside of the room 20 can be closed by a perforated floor 24, so that air can also flow into the room 20 from the underside of the device.

Die unten an der Gehäuseunterseite zumindest an vier Stellen befestigte flache Abdeckung 10 steht mit Ihren Rändern über die Außenabmessungen des Lüftergehäuses rundum vor. Die Abdeckung kann quadratisch oder rechteckförmig ausgeführt sein, wobei vorzugsweise die Ecken abgerundet sind. Die Abdeckung 10 weist von unten gesehen eine konvexe Krümmung auf.The edges of the flat cover 10, which is fastened at least in four places on the underside of the housing, protrudes with its edges beyond the outer dimensions of the fan housing. The cover can be square or rectangular, the corners preferably being rounded. The cover 10 has a convex curvature when viewed from below.

Die Abdeckung 10 ist in einem Abstand zur Gehäuseunterseite befestigt, so daß zwischen Abdeckung 10 und Gehäuseunterseite ein Zwischenraum besteht, durch den die angesaugte Luft sich verteilen kann und ferner der Filter 9 angeordnet ist.The cover 10 is attached at a distance from the underside of the housing, so that there is a space between the cover 10 and the underside of the housing through which the sucked air can distribute and the filter 9 is also arranged.

Besonders vorteilhaft ist es, wenn die Abdeckung 10 in regelmäßigem Abstand zahlreiche Luftdurchtrittsöffnungen besitzt, so daß durch die Abeckung hindurch Luft ansaugbar ist.It is particularly advantageous if the cover 10 has numerous air passage openings at regular intervals, so that air can be drawn in through the cover.

Die Abdeckung ist von einer Scheibe oder Platte aus Metall, Kunststoff oder Glas gebildet.The cover is formed by a disc or plate made of metal, plastic or glass.
