Abstract
Die Vorrichtung (1) ist für die Erzeugung eines Schaum aufweisenden Reinigungsstrahls gedacht, welcher aus der Verwirbelung eines Gases, insbesondere Luft, und Wasser gebildet wird. Ein Frischwasserstrahl tritt auf einer Stirnseite der Vorrichtung (1) außermittig in diese durch eine Drosselöffnung 17 ein, durchquert die Vorkammer (6) und trifft in der Mischkammer (3) auf eine Prallwand (5), welche zu einer Verwirbelung des Frischwasserstrahls und somit zur Schaumbildung führt. Dabei entsteht in der Vorrichtung ein Unterdruck, durch welchen permanent Außenluft durch eine Gaseintrittsöffnung (14) in die Vorrichtung (1) eingesogen wird und zur Schaumbildung zur Verfügung steht. Ein so gebildeter Schaum tritt durch die Austrittsöffnungen (7), die ringförmig in einer Mantelfläche der rotationssymmetrischen Mischkammer (3) angeordnet sind, in eine zweite Mischkammer (8), in der aus mehreren Austrittsstrahlen ein Schaum aufweisender Reinigungsstrahl gebildet wird, welcher aus der Vorrichtung (1) durch eine weitere Austrittsöffnung (9) entnommen werden kann. Vorteilhaft erlaubt eine derartige Anordnung die Bildung eines Reinigungsstrahls, dessen Volumenstrom konstant ist und der die Vorrichtung nicht pulsierend verlässt. Ferner ist vorgesehen, an die Austrittsöffnung (9) einen Schlauch (12, 14) oder ein Rohr anzuschließen, um eine Entnahmeeinrichtung wie beispielsweise einen Wasserhahn (15) zur Entnahme des Schaum aufweisenden Reinigungsstrahls in Abstand von der Vorrichtung (1) anordnen zu können.The device (1) is intended for the production of a foam-containing cleaning jet, which is formed from the turbulence of a gas, in particular air, and water. A fresh water jet occurs on one end side of the device (1) off-center into this through a throttle opening 17, passes through the pre-chamber (6) and meets in the mixing chamber (3) on a baffle (5), which to a turbulence of the fresh water jet and thus to Foaming leads. In this case, a negative pressure arises in the device, through which permanent outside air is sucked through a gas inlet opening (14) into the device (1) and is available for foaming. A foam thus formed passes through the outlet openings (7), which are arranged annularly in a lateral surface of the rotationally symmetrical mixing chamber (3), into a second mixing chamber (8) in which a cleaning jet having a foam is formed from a plurality of outlet jets (1) can be removed through a further outlet opening (9). Advantageously, such an arrangement allows the formation of a cleaning jet whose volume flow is constant and which does not leave the device pulsating. It is further provided to connect to the outlet opening (9) a hose (12, 14) or a pipe in order to arrange a removal device such as a faucet (15) for removing the foam having cleaning jet at a distance from the device (1).
Description
Die Erfindung betrifft eine Vorrichtung zur Erzeugung eines Schaum aufweisenden Reinigungsstrahls mit einem Frischwasserzulauf sowie mit einer mit dem Frischwasserzulauf verbundenen, zu ihrer Längsachse rotationssymmetrischen Mischkammer, die eine Drosselöffnung für die Bildung eines Frischwassereintrittsstrahls, eine Gaseintrittsöffnung für Schaum bildendes Gas, eine Austrittsöffnung für einen Schaum aufweisenden Austrittsstrahl und eine der Drosselöffnung gegenüberliegende, den Frischwassereintrittsstrahl empfangende Prallwand aufweist, wobei die Mischkammer eine Vorkammer umfasst und die Drosselöffnung an der dem Frischwasserzulauf zugewandten Stirnfläche der Vorkammer vorgesehen ist. The invention relates to a device for generating a foam cleaning jet having a fresh water inlet and connected to the fresh water inlet, rotationally symmetrical to its longitudinal axis mixing chamber having a throttle opening for the formation of a fresh water inlet jet, a gas inlet opening for foam-forming gas, an outlet opening for a foam Outlet jet and one of the throttle opening opposite, the fresh water inlet jet receiving baffle, wherein the mixing chamber comprises a prechamber and the throttle opening is provided at the fresh water inlet facing end face of the prechamber.
Eine solche Vorrichtung ist aus der
Der vorliegenden Erfindung liegt daher die Aufgabe zugrunde, eine Vorrichtung zur Erzeugung eines Schaum aufweisenden Reinigungsstrahls zu schaffen, die einen konstanten Volumenstrom durch die Austrittsöffnung ermöglicht. The present invention is therefore based on the object to provide a device for generating a foam having cleaning jet, which allows a constant flow through the outlet opening.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, dass die Vorrichtung eine zweite Mischkammer aufweist, in die der Austrittsstrahl nach dem Verlassen der ersten Mischkammer durch die Austrittsöffnung eintritt und ein in der zweiten Mischkammer gebildeter, Schaum aufweisender Reinigungsstrahl durch eine weitere Austrittsöffnung aus der Vorrichtung ausströmen kann. This object is achieved in that the device has a second mixing chamber into which the exit jet enters after leaving the first mixing chamber through the outlet opening and a formed in the second mixing chamber, foam having cleaning jet can flow out through a further outlet opening of the device.
Vorteilhaft wird durch die kaskadenartige Anordnung der beiden Mischkammern ein konstanter Volumenstrom erreicht, so dass an einer Entnahmestelle ein konstant fließender, nicht pulsierender Reinigungsstrahl entnommen werden kann. Advantageously, a constant volume flow is achieved by the cascade-like arrangement of the two mixing chambers, so that at a sampling point, a constantly flowing, non-pulsating cleaning jet can be removed.
Überraschenderweise hat der Erfinder auch festgestellt, dass ein mittels der erfindungsgemäßen Vorrichtung erzeugter Reinigungsstrahl einen höheren Schaumanteil aufweist als ein vergleichbarer Reinigungsstrahl, welcher mittels der aus dem Stand der Technik bekannten Vorrichtung erzeugt wird. Surprisingly, the inventor has also found that a cleaning jet generated by means of the device according to the invention has a higher proportion of foam than a comparable cleaning jet, which is produced by means of the device known from the prior art.
Zweckmäßigerweise ist die zweite Mischkammer zur Bildung des Schaum aufweisenden Reinigungsstrahls koaxial zur Rotationsachse der ersten Mischkammer angeordnet. Expediently, the second mixing chamber is arranged coaxially with the axis of rotation of the first mixing chamber for forming the cleaning jet having foam.
In einer weiteren Ausführungsform ist die zweite Mischkammer ringförmig um wenigstens einen Abschnitt der ersten Mischkammer angeordnet. Dies ermöglicht insbesondere eine kompakte Bauweise der Vorrichtung. In a further embodiment, the second mixing chamber is arranged annularly around at least a portion of the first mixing chamber. This allows in particular a compact design of the device.
In einer bevorzugten Ausführungsform sind mindestens zwei Austrittsöffnungen, die in einen Endbereich der zweiten Mischkammer einmünden, in einer Mantelfläche der ersten Mischkammer angeordnet. Dadurch kann ein Schaum aufweisender Austrittsstrahl aus der ersten Mischkammer austreten, ohne den in die erste Mischkammer eintretenden Frischwasserstrahl zu kreuzen. Ein solches Kreuzen von Eintritts- und Austrittsstrahlen wirkt sich negativ auf die Schaumbildung in der ersten Mischkammer aus und führt erfahrungsgemäß bei dem bereits gebildeten Schaum zu einer teilweisen Entmischung. Auch hat sich gezeigt, dass in einem Bereich um die Prallwand, in dem sich die Eintritts- und Austrittsstrahlen kreuzen, zusätzliche Verwirbelungen entstehen, die zu einem pulsierenden Austreten des Reinigungsstrahls durch die Austrittsöffnung führen. In a preferred embodiment, at least two outlet openings, which open into an end region of the second mixing chamber, are arranged in a lateral surface of the first mixing chamber. As a result, a foam-containing exit jet can emerge from the first mixing chamber without crossing the fresh water jet entering the first mixing chamber. Such crossing of inlet and outlet jets has a negative effect on the foam formation in the first mixing chamber and, according to experience, leads to partial segregation in the already formed foam. It has also been found that in a region around the baffle wall, in which the inlet and outlet jets intersect, additional turbulences arise, which lead to a pulsating emergence of the cleaning jet through the outlet opening.
Zweckmäßigerweise stimmen die Austrittsöffnungen in ihren Abmessungen und/oder ihrer Geometrie überein und sind bevorzugt kreisrund. Damit ist sichergestellt, dass einerseits alle Austrittsöffnungen einen gleichen oder in etwa gleichen Strömungswiderstand aufweisen und somit durch jede Austrittsöffnung ein gleichgroßer oder in etwa gleichgroßer Volumenstrom fließen kann. Appropriately, the outlet openings are consistent in their dimensions and / or their geometry and are preferably circular. This ensures that, on the one hand, all outlet openings have the same or approximately the same flow resistance, and thus an equal or substantially equal volume flow can flow through each outlet opening.
In einer weiteren Ausführungsform sind mehr als zwei Austrittsöffnungen entsprechend einem Ring angeordnet, wobei die Ringachse koaxial zur Zylinderachse der ersten Mischkammer angeordnet ist. Dadurch werden die Schaum aufweisenden Austrittsstrahlen aus der Mischkammer abgeleitet derart, dass ein Kreuzen des Schaum aufweisenden Austrittsstrahls beim Verlassen der Mischkammer mit dem eintretenden Frischwasserstrahl vermieden wird. In a further embodiment, more than two outlet openings are arranged corresponding to a ring, wherein the ring axis is arranged coaxially to the cylinder axis of the first mixing chamber. Characterized the foam having exit jets are derived from the mixing chamber such that a crossing of the foam having exit jet is avoided when leaving the mixing chamber with the incoming fresh water jet.
Zweckmäßigerweise sind die Austrittsöffnungen gleichmäßig über den Umfang der Mischkammer verteilt angeordnet. Conveniently, the outlet openings are arranged distributed uniformly over the circumference of the mixing chamber.
In einer besonderen Ausführungsform strömen die Austrittsstrahlen bevorzugt senkrecht zur Rotationsachse der zweiten Mischkammer in die zweite Mischkammer ein. Es wäre auch denkbar, einige Austrittsstrahlen unter einem anderen Winkel als 90° auftreffen zu lassen oder/und einige Austrittsstrahlen durch verschieden große Austrittsöffnungen aus der Mischkammer austreten zu lassen. Es hat sich gezeigt, dass durch ein senkrechten Auftreffen der Austrittsstrahlen auf eine Mantelfläche der zweiten Mischkammer eine zusätzliche Verwirbelung entsteht, die ein weiteres Aufschäumen der in die zweite Mischkammer eintretenden Austrittsstrahlen hervorruft. Ferner hat sich gezeigt, dass bei Einströmwinkeln kleiner 90° der Volumenstrom durch die weitere Austrittsöffnung erhöht wird. In a particular embodiment, the exit jets preferably flow into the second mixing chamber perpendicular to the axis of rotation of the second mixing chamber. It would also be conceivable to let some exit jets impinge at an angle other than 90 ° and / or to let escape some outlet jets through different sized outlet openings from the mixing chamber. It has been shown that by a vertical impact of the exit jets on a lateral surface of the second mixing chamber, an additional turbulence is created, the further foaming in the second Mixing chamber entering exit jets causes. Furthermore, it has been shown that at inflow angles smaller than 90 °, the volume flow through the further outlet opening is increased.
In einer weiteren Ausführungsform ist ein Rohr und/oder ein Schlauch zum Anschluss an die weitere Austrittsöffnung der Vorrichtung vorgesehen, so dass ein Schaum aufweisender Reinigungsstrahl vorteilhaft zu einer Entnahmestelle geführt werden kann. In a further embodiment, a pipe and / or a hose is provided for connection to the further outlet opening of the device, so that a cleaning jet having foam can be advantageously guided to a removal point.
Zweckmäßigerweise ist eine Einrichtung zur Entnahme des Schaum aufweisenden Reinigungsstrahls über das Rohr oder den Schlauch, insbesondere eine Bad- oder Küchenarmatur, vorzugsweise ein Wasserhahn, vorgesehen. Eine solche Anordnung ermöglicht vorteilhaft die Führung des Schaum aufweisenden Reinigungsstrahls an Orte, an denen aus Platzgründen eine Installation der Vorrichtung nicht möglich oder nicht gewünscht ist. Appropriately, a device for removing the foam having cleaning jet through the pipe or hose, in particular a bath or kitchen faucet, preferably a faucet provided. Such an arrangement advantageously allows the guidance of the foam having cleaning jet to places where installation of the device is not possible or not desirable for reasons of space.
In einer besonderen Ausführungsform weist das an die Austrittsöffnung angeschlossene Rohr oder der an die Austrittsöffnung angeschlossene Schlauch an einem offenen Ende ein Verzweigungsstück mit wenigstens zwei Abzweigungen auf, wobei an die Öffnung der Abzweigungen Schläuche und/oder Rohre anschließbar sind, an deren Enden sich die Entnahmeeinrichtung für den Schaum aufweisenden Reinigungsstrahl befindet. Dadurch wird vorteilhaft ermöglicht, dass der Reinigungsstrahl auf weitere Entnahmeeinrichtungen verteilt werden kann und beispielsweise nicht jeder Wasserhahn eine eigene Vorrichtung zur Schaumbildung benötigt, sondern eine einzige Vorrichtung mehrere Wasserhähne zentral versorgen kann. Dies wäre u.a. bei einem Einsatz in Gemeinschaftsduschen vorteilhaft, bei denen mehrere Waschstationen mit dem Schaum aufweisenden Reinigungsstrahl zu versorgen sind. Ebenso ist es denkbar, eine solche Vorrichtung in einem Badbereich anzubringen, wo neben einer Mischbatterie einer Dusche auch ein Wasserhahn mit einem Schaum aufweisenden Reinigungsstrahl zu versorgen ist. In a particular embodiment, the tube connected to the outlet opening or the tube connected to the outlet opening at an open end has a branch piece with at least two branches, wherein hoses and / or tubes can be connected to the opening of the branches, at the ends of which the removal device for the foam having cleaning jet is located. This advantageously makes it possible that the cleaning jet can be distributed to other removal devices and, for example, not every faucet requires its own device for foaming, but a single device can supply several faucets centrally. This would be u.a. advantageous for use in shared showers, where multiple wash stations are to be supplied with the foam having cleaning jet. Likewise, it is conceivable to install such a device in a bath area, where in addition to a mixer tap a shower and a faucet to be supplied with a foam cleaning jet.
Zweckmäßigerweise ist die Gaseintrittsöffnung mit einem Rückschlagventil versehen. Dadurch wird sichergestellt, dass kein Wasser aus der ersten Mischkammer oder der Vorkammer durch die Gaseintrittsöffnung austreten kann, wenn an einer Entnahmeposition beispielsweise ein Wasserhahn geschlossen wird und somit kein Schaum aufweisender Reinigungsstrahl mehr aus der Vorrichtung weggeführt wird. Conveniently, the gas inlet opening is provided with a check valve. This ensures that no water from the first mixing chamber or the pre-chamber can escape through the gas inlet opening when, for example, a faucet is closed at a removal position and thus no foam having cleaning jet is led away from the device.
In einer Ausführungsform wird das Rückschlagventil durch Unterdruck geöffnet, der entsteht, wenn der Frischwassereintrittsstrahl durch die Drosselöffnung in die Vorrichtung einströmt. Dadurch kann von außen das Gas oder/und Umgebungsluft in die Vorrichtung eintreten, so dass permanent neuer Schaum gebildet und der Reinigungsstrahl an den Entnahmeeinrichtungen entnommen werden kann. Wird kein Reinigungsstrahl mehr entnommen, so schließt das Rückschlagventil wieder. In one embodiment, the check valve is opened by negative pressure, which arises when the fresh water inlet jet flows through the throttle opening in the device. As a result, the gas and / or ambient air can enter the device from the outside, so that new foam can be permanently formed and the cleaning jet can be removed at the removal devices. If no cleaning jet removed, the check valve closes again.
In einer weiteren Ausführungsform ist an der Vorkammer eine Eintrittsöffnung vorgesehen, durch die ein Reinigungsmittel, vorzugsweise Seife oder Duschgel oder Shampoo, aus einem Reinigungsmittelbehälter in die Vorkammer eingebracht werden kann. Dadurch kann der Schaum aufweisende Reinigungsstrahl sowohl weiter aufgeschäumt werden und eine durch das Reinigungsmittel hervorgerufene, zusätzliche Reinigungswirkung kann erreicht werden. In a further embodiment, an inlet opening is provided on the antechamber, through which a cleaning agent, preferably soap or shower gel or shampoo, can be introduced from a detergent container into the prechamber. As a result, the cleaning jet having the foam can be further foamed on and an additional cleaning effect caused by the cleaning agent can be achieved.
Es versteht sich, dass die zweite Mischkammer auch eine andere Querschnittsfläche als eine kreisförmige Fläche aufweisen kann. So wäre es möglich, diese Querschnittsfläche beispielsweise viereckig oder in Form eines Polygons auszubilden. It is understood that the second mixing chamber may also have a different cross-sectional area than a circular area. So it would be possible to form this cross-sectional area, for example, quadrangular or in the form of a polygon.
Im Folgenden wird die Erfindung anhand von Ausführungsbeispielen weiter erläutert. Es zeigen: In the following the invention will be further explained by means of exemplary embodiments. Show it:
