Description

Die vorliegende Erfindung betrifft eine Vorrichtung zur Vernebelung einer Flüssigkeit mit einem Behälter für die Aufnahme der zu vernebelnden Flüssigkeit und wenigstens drei Schwingern zur Erzeugung von Ultraschallschwingungen, die in dem Behälter angeordnet sind und die ein die Schwingungen auf die Flüssigkeit übertragende ebene Fläche aufweisen, wobei die Flächen nicht parallel zueinander sind.The present invention relates to a device for atomizing a liquid with a container for receiving the liquid to be atomized and at least three vibrators for generating ultrasonic vibrations, which are arranged in the container and which have a flat surface which transmits the vibrations to the liquid, the Surfaces are not parallel to each other.

Aus dem Stand der Technik ist es bekannt, zur Vernebelung von Flüssigkeiten Ultraschallschwinger einzusetzen. Durch die hochfrequenten mechanischen Schwingungen werden aus einer Flüssigkeit, die die Schwinger benetzt oder überflutet, kleine Flüssigkeitstropfen herausgerissen. Dadurch bildet sich über der Flüssigkeit ein Aerosol oder Nebel, der von einem Gasstrom, insbesondere einem Luftstrom fortgetragen wird. Je nach Verwendungszweck kann es gewünscht sein, dass der Nebel erhalten bleibt, um zu wirken. Es ist aber auch möglich, dass es gewünscht ist, dass die Flüssigkeitstropfen verdampfen und der Dampf die erwünschte Wirkung erzielt.It is known from the prior art to use ultrasonic vibrators for atomizing liquids. The high-frequency mechanical vibrations pull small drops of liquid out of a liquid that wets or floods the transducers. As a result, an aerosol or mist forms above the liquid, which is carried away by a gas stream, in particular an air stream. Depending on the intended use, it may be desirable that the fog remains in order to work. However, it is also possible that it is desirable for the liquid drops to evaporate and for the vapor to have the desired effect.

Ungeachtet des Einsatzzwecks für den die Flüssigkeit vernebelt wird, wünscht sich jeder Anwender einer eingangs genannten Vorrichtung eine hohe Vernebelungsleistung, d.h. eine möglichst hohe Menge vernebelter Flüssigkeit pro Zeiteinheit. Dabei - so ein weiterer Wunsch der Anwender - soll möglichst wenig Energie und ein möglichst kleines Gerät eingesetzt werden.Regardless of the purpose for which the liquid is atomized, every user of a device mentioned at the outset wishes a high atomization performance, i.e. the highest possible amount of atomized liquid per unit of time. Another user request is that as little energy and as small a device as possible should be used.

In der Vergangenheit wurden zum Beispiel Vorrichtungen eingesetzt, wie sie in den Dokumenten JP2008100204 , US 2016/0158788 A1 , EP 0 860 211 A1 und WO 2010/100462 A1 offenbart sind. Diese offenbaren u.a. Vorrichtungen der eingangs genannten Art, bei denen die Flächen der Schwinger nach innen geneigt sind, das heißt, dass die auf den Flächen der Schwinger beginnenden und dazu senkrechten Halbgeraden von allen Schwingern in Ebenen liegen, die sich in einer Geraden schneiden, wobei sich alle Halbgeraden und diese Gerade in einem Punkt schneiden. Durch eine solche Anordnung der Schwinger kann ein grundsätzlich zufriedenstellendes Ergebnis erzielt werden.For example, devices such as those used in the documents have been used in the past JP2008100204 , US 2016/0158788 A1 , EP 0 860 211 A1 and WO 2010/100462 A1 are disclosed. These disclose devices of the type mentioned at the outset, in which the surfaces of the transducers are inclined inwards, that is to say that on the Surfaces of the transducers beginning and perpendicular to them half lines of all transducers lie in planes that intersect in a straight line, with all half lines and this straight line intersecting at one point. By arranging the transducers in this way, a fundamentally satisfactory result can be achieved.

Ziel der vorliegenden Erfindung ist es alternative Vorrichtungen vorzuschlagen, die möglichst eine bessere Vernebelungsleistung haben.The aim of the present invention is to propose alternative devices that have better nebulization performance.

Dieses Ziel wird dadurch erreicht, dass die Schwinger so ausgerichtet sind, dass zu den Flächen der Schwinger senkrechte erste Geraden von allen Schwingern windschief zueinander sind und auf der Fläche eines Rotationshyperboloids liegen..This goal is achieved in that the transducers are aligned in such a way that first lines of all transducers perpendicular to the surfaces of the transducers are skewed to one another and lie on the surface of a rotational hyperboloid.

Die Flächen der Schwinger können in einer geschlossenen Kette dem jeweils nächsten Schwinger zugeneigt sein.The surfaces of the transducers can be inclined towards the next transducer in a closed chain.

Insbesondere bei dieser Variante haben Versuche eine hohe Vernebelungsleistung erbracht.In this variant in particular, tests have shown a high atomization performance.

Ferner ist es möglich, dass bei einer erfindungsgemäßen Vorrichtung die Schwinger auf einem Kreis angeordnet sind, also gleiche Punkte der Schwinger in einer Ebene mit einer gleichen Entfernung zu einem Mittelpunkt des Kreises angeordnet sind. Dann können die Schwinger so ausgerichtet sein, dass die zu den Flächen senkrechten ersten Geraden von allen Schwingern Tangenten an einen vorzugsweise geraden Kreiszylinder bilden, der einen Durchmesser hat, der kleiner ist als der Durchmesser des Kreises, auf dem die Schwinger angeordnet sind, und dessen Mittelachse durch einen Mittelpunkt dieses Kreises geht. Vorzugsweise ist die Entfernung aller Berührungspunkte der Tangenten von dem Kreis gleich.Furthermore, it is possible that, in a device according to the invention, the oscillators are arranged on a circle, that is to say the same points of the oscillators are arranged in a plane with the same distance from a center of the circle. Then the oscillators can be aligned such that the first straight lines perpendicular to the surfaces of all oscillators form tangents to a preferably straight circular cylinder, which has a diameter which is smaller than the diameter of the circle on which the oscillators are arranged, and its Center axis goes through a center of this circle. The distance of all points of contact of the tangents from the circle is preferably the same.

Die erste und zweite dargestellte erfindungsgemäße Vorrichtung weisen jeweils eine Wanne W auf, welche über einen Flüssigkeitseinlauf mit einer Flüssigkeit befüllt werden kann. Die Befüllung kann mittels einer Pumpe kontinuierlich erfolgen, so dass ein konstanter oder nahezu konstanter Flüssigkeitsspiegel in der Wanne W gehalten werden kann, auch wenn durch Vernebelung von Teilen der Flüssigkeit Flüssigkeit aus der Wanne W entnommen wird.The first and second illustrated device according to the invention each have a trough W, which can be filled with a liquid via a liquid inlet. The filling can be carried out continuously by means of a pump, so that a constant or almost constant liquid level can be maintained in the tub W, even if liquid is removed from the tub W by atomizing parts of the liquid.

Die erste dargestellte erfindungsgemäße Vorrichtung weist vier Ultraschallschwinger 1, 2, 3, 4 auf, die zweite erfindungsgemäße Vorrichtung weist sieben Ultraschallschwinger 1, 2, 3, 4, 5, 6, 7 auf. Diese sind bei beiden dargestellten erfindungsgemäßen Vorrichtungen so in der Wanne W angeordnet, dass im Betrieb der Vorrichtungen jeder Schwinger 1, 2, 3, 4, 5, 6, 7 unter dem Flüssigkeitsspiegel liegt. Jeder Schwinger 1, 2, 3, 4, 5, 6, 7 hat eine im Betrieb der Vorrichtung oszillierende Fläche F, über die der Schwinger 1, 2, 3, 4, 5, 6, 7 die Oszillation auf die Flüssigkeit übertragen kann. Dadurch wird die Flüssigkeit zum Schwingen angeregt und kleine Flüssigkeitstropfen werden herausgeschleudert. Dadurch entsteht ein Nebel, der von einem Luftstrom vorgetragen werden kann. Die Vorrichtungen weisen dazu nicht dargestellte Luftfördermittel und -kanäle auf, über welche der Luftstrom zugeführt und der Nebel aufgeführt werden kann. Die Flächen F der Schwinger 1, 2, 3, 4, 5, 6, 7 sind vorzugsweise eben.The first device according to the invention shown has four ultrasonic vibrators 1, 2, 3, 4, the second device according to the invention has seven ultrasonic vibrators 1, 2, 3, 4, 5, 6, 7. In both of the devices according to the invention shown, these are arranged in the tub W such that each device 1, 2, 3, 4, 5, 6, 7 is below the liquid level when the devices are in operation. Each oscillator 1, 2, 3, 4, 5, 6, 7 has a surface F which oscillates during operation of the device, via which the oscillator 1, 2, 3, 4, 5, 6, 7 can transmit the oscillation to the liquid. This will make the Liquid is stimulated to vibrate and small drops of liquid are thrown out. This creates a mist that can be carried by an air stream. For this purpose, the devices have air conveying means and channels, not shown, via which the air flow can be supplied and the mist can be performed. The surfaces F of the transducers 1, 2, 3, 4, 5, 6, 7 are preferably flat.

Die vier Schwinger 1, 2, 3, 4 sind bei der ersten dargestellten erfindungsgemäßen Vorrichtungen an den Ecken eines gedachten Quadrates angeordnet. Die Ausrichtung der Flächen F der Schwinger 1, 2, 3, 4 wird durch erste Geraden G1 beschrieben, die man sich senkrecht zu der Fläche F der Schwinger 1, 2, 3, 4 vorstellen kann und die den Figuren 8 und 9 dargestellt sind. Auch bei der zweiten dargestellten erfindungsgemäßen Vorrichtung wird die Ausrichtung der Flächen F der Schwinger 1, 2, 3, 4, 5, 6, 7 durch erste Geraden G1 beschrieben (siehe Figur 10).The four transducers 1, 2, 3, 4 are arranged at the corners of an imaginary square in the first inventive device shown. The alignment of the surfaces F of the oscillators 1, 2, 3, 4 is described by first straight lines G1, which can be imagined perpendicular to the surface F of the oscillators 1, 2, 3, 4 and which are shown in FIGS. 8 and 9. In the second device according to the invention, the alignment of the surfaces F of the oscillators 1, 2, 3, 4, 5, 6, 7 is also described by first straight lines G1 (see FIG. 10).

Die ersten Geraden G1, die senkrecht auf den Flächen F der Schwinger 1, 2, 3, 4 der ersten dargestellten erfindungsgemäßen Vorrichtung stehen, sind windschief zueinander und schneiden sich in keinem Punkt. Zur Beschreibung der Ausrichtung der um 7° geneigten Flächen F der Schwinger 1, 2, 3, 4 kann man sich ein gerades Prisma oder einen Quader vorstellen, dessen Grundfläche G durch das Quadrat beschrieben wird, in dessen Ecken die vier Schwinger angeordnet sind. Kanten dieses Prismas oder Quaders sollen dabei durch die Flächen F der Schwinger 1, 2, 3, 4 verlaufen. Die Flächen F der Schwinger 1, 2, 3, 4 sind so ausgerichtet, dass die ersten Geraden G1 in den Seitenflächen des Prismas oder Quaders liegen. Die Flächen sind ferner so ausgerichtet, dass die ersten Geraden G1, die senkrecht auf den Flächen F der Schwinger 1, 2, 3, 4 liegen die die Kanten des Prismas oder Quaders schneiden, die durch die Fläche F des in der Draufsicht auf die Vorrichtung im Uhrzeigersinn benachbarten Schwinger 1, 2, 3, 4 schneidet.The first straight lines G1, which are perpendicular to the surfaces F of the oscillators 1, 2, 3, 4 of the first device according to the invention, are skewed to one another and do not intersect at any point. To describe the alignment of the surfaces F inclined by 7 ° of the transducers 1, 2, 3, 4, one can imagine a straight prism or a cuboid whose base surface G is described by the square, in the corners of which the four transducers are arranged. Edges of this prism or cuboid should run through the surfaces F of the oscillators 1, 2, 3, 4. The surfaces F of the transducers 1, 2, 3, 4 are aligned such that the first straight lines G1 lie in the side surfaces of the prism or cuboid. The surfaces are also aligned such that the first straight lines G1, which are perpendicular to the surfaces F of the transducers 1, 2, 3, 4, intersect the edges of the prism or cuboid, which through the Surface F of the oscillator 1, 2, 3, 4 adjacent in the plan view of the device intersects clockwise.

Man kann die Ausrichtung auch so beschreiben, dass die ersten Geraden G1 auf der Fläche eines Rotationshyperboloiden liegt, der entsteht, wenn man eine der ersten Geraden G1 um eine Achse A rotiert, die senkrecht auf der Mitte des Quadrates steht, das die Positionen der Schwinger 1, 2, 3, 4 beschreibt.The alignment can also be described in such a way that the first straight line G1 lies on the surface of a rotational hyperboloid, which arises when one of the first straight lines G1 rotates about an axis A that is perpendicular to the center of the square that defines the positions of the oscillators 1, 2, 3, 4 describes.

Die zweite erfindungsgemäße Vorrichtung weist sieben Schwinger 1, 2, 3, 4, 5, 6, 7 auf, die in Kreisform angeordnet sind. Gleiche Punkte der Schwinger 1, 2, 3, 4, 5, 6, 7 sind gleich weit vom Mittelpunkt eines Kreises K entfernt. Die Flächen dieser Schwinger 1, 2, 3, 4, 5, 6, 7 sind so ausgerichtet, dass die ersten Geraden G1 der Schwinger Tangenten an einen Kreiszylinder Z bilden. Der Kreiszylinder Z hat eine Mittelachse, die durch den Mittelpunkt des Kreises K verläuft. Die Mittelachse steht vorzugsweise senkrecht auf einer Ebene, in der sich der Kreis erstreckt.The second device according to the invention has seven oscillators 1, 2, 3, 4, 5, 6, 7, which are arranged in a circular shape. The same points of the transducers 1, 2, 3, 4, 5, 6, 7 are equidistant from the center of a circle K. The surfaces of these oscillators 1, 2, 3, 4, 5, 6, 7 are aligned such that the first straight lines G1 of the oscillators form tangents to a circular cylinder Z. The circular cylinder Z has a central axis which runs through the center of the circle K. The central axis is preferably perpendicular to a plane in which the circle extends.

Die Entfernung von Berührungspunkten aller Tangente von dem Kreis K ist bei der zweiten erfindungsgemäßen Vorrichtung gleich.The distance of points of contact of all tangents from the circle K is the same in the second device according to the invention.
