A narrow gap-like intermediate space (18) is formed between the end faces and a side wall. The air feed chamber is located on the side of the side wall away from the plate pairs. Air passes into the chamber, through the side wall, and into the spaces between the plate pairs. The chamber is closed to the outside by a cover (21) with air intake apertures.

Description

Die Erfindung betrifft einen Lüfter insbesondere Deckenlüfter mit mindestens einem Luftauslaß, vor dem Lamellenpaare befestigt sind, wobei ein Lamellenpaar zwischen seinen zwei Lamellen einen Zwischenraum bildet, in den über die Stirnseiten Luft eintritt.The invention relates to a fan, in particular a ceiling fan with at least one air outlet, in front of which pairs of fins are fastened, a pair of fins forming an intermediate space between its two fins, into which air enters via the end faces.

Es sind Deckenlüfter für größerer Räume bekannt, die mehrere Luftauslasse seitlich besitzen, in denen Lamellen zur Luftführung befestigt sind. Darüberhinaus sind Lüfter bekannt, bei denen die Lamellen paarweise angeordnet und soweit vor dem Luftauslaß angeordnet sind, daß die jeweils von zwei Lamellen gebildeten Zwischenräume an den Stirnseiten offen sind, um dort Luft in den Zwischenraum einsaugen zu können. Bei diesen bekannten Geräten stehen die Lamellenpaare verhältnismäßig weit über die Außenabmessungen des Lüftergehäuses hinaus.Ceiling fans for larger rooms are known which have several air outlets on the side, in which fins are attached for air guidance. In addition, fans are known in which the fins are arranged in pairs and so far in front of the air outlet that the gaps formed by two fins are open at the end faces in order to be able to suck air into the space there. In these known devices, the pairs of fins are relatively far beyond the outer dimensions of the fan housing.

Aufgabe der Erfindung ist es, einen Lüfter, insbesondere einen Deckenlüfter so zu verbessern, daß stirnseitig luftansaugende Lamellenpaare über die Gehäuseaußenabmessungen nicht oder nur wenig hinausstehen und dennoch stirnseitig ausreichend Luft ansaugen können. Dabei soll bei einfacher Konstruktion und geringen Außenabmessungen ein hoher Wirkungsgrad erzielt werden.The object of the invention is to improve a fan, in particular a ceiling fan, in such a way that pairs of air-sucking louvres do not protrude beyond the outer dimensions of the housing, or protrude only slightly, and nevertheless can suck in sufficient air at the end. A high degree of efficiency is to be achieved with a simple construction and small external dimensions.

Diese Aufgaben werden erfindungsgemäß dadurch gelöst, daß die offenen Stirnseiten der Lamellenpaare jeweils durch eine Seitenwand bedeckt sind, die Luftdurchtrittsöffnungen aufweisen.According to the invention, these objects are achieved in that the open end faces of the pairs of lamellae are each covered by a side wall which has air passage openings.

Durch eine solche Lösung werden Lüfter, insbesondere Deckenlüfter geschaffen, deren Lamellenpaare nicht über die Außenabmessungen des Lüftergehäuses hinausstehen, wobei dennoch die Lamellenpaare zu beiden Stirnseiten ausreichend Luft ansaugen, die mit dem vom Lüfterrad erzeugten Luftstrom sich vermischt, sobald dieser Luftstrom die Lamellenapaare nach außen verläßt. Es wird damit eine Konstruktion erreicht, bei der die austretende Luft weit in den Raum gelangt und dennoch die Lamellenpaare nicht über das Lüftergehäuse hinausrasen, so daß sie geschützt und formschön einliegen.Such a solution creates fans, in particular ceiling fans, whose louvre pairs do not protrude beyond the outer dimensions of the fan housing, the louvre pairs nevertheless sucking in sufficient air on both ends, which mixes with the airflow generated by the fan wheel as soon as this airflow leaves the louvre pairs to the outside . A construction is thus achieved in which the escaping air reaches far into the room and yet the pairs of fins do not race past the fan housing, so that they lie in a protected and shapely manner.

Vorteilhafte Ausgestaltungen der Erfindung sind in den Unteransprüchen aufgeführt.Advantageous embodiments of the invention are listed in the subclaims.

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 each of its four sides and corner areas 12 lying 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 designed in a sieve shape. 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. For The inside of the air supply space 20 is delimited by an air-impermeable inner wall 22 which is arranged obliquely such 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.
