Abstract

A cleansing foam generator suitable for cleaning hospitals, canteens, offices and animal sheds etc., has a frame mounted on wheels with a motor driven air compressor used to apply pressure to a liquid foaming agent, and is designed for silent operation. The space between the inner and outer walls of a cylindrical double walled vessel is used as the liquid container, and houses the compressor inside the inner wall. This inner wall is corrugated, with a set of annular ribs extending inwards from the inside of the inner wall. The compressor is mounted on a platform supported by slides inside the container.

Description

Sprühvorrichtung für ein Reinigungsmittel Die Erfindung betrifft eine Vorrichtung zum Aufsprühen eines Reinigungsmittels auf einen Gegenstand. Die Vorrichtung verfügt über eine Einrichtung, wie beispielsweise eine Pumpe oder Luftkompressor, zur Schaffung einesDrucks in dem Mittel, das flüssig sein kann, und über einen Motor zum Antrieb der Pumpe und über einen druckfesten Tank für das Mittel. Die Vorrichtung kann mit einem Puffertank, mit Leitungen und Ventilen und miteiner Mischkammer zur Erzeugung des Schaums ausgestattet sein. Spray device for a cleaning agent The invention relates to a device for spraying a cleaning agent onto an object. the The device has a device, such as a pump or air compressor, to create a pressure in the agent, which may be liquid, and via a motor to drive the pump and via a pressure-tight tank for the agent. The device can with a buffer tank, with pipes and valves and with a mixing chamber Generation of the foam be equipped.

Entsprechende Vorrichtungen sind bereits vorgeschlagen worden, jedoch besteht ihr Nachteil in dem von dem Kompressor und/oder der Hochdruckwasserpumpe erzeugten Lärm, der im höchsten Maße unerwünscht ist und der in vielen Fällen, insbesondere in Räumen bzw. in Gebäuden mit einer Lebenshaltung und in Krankenhäusern, Kantinen, Büros etc., sogar so groß ist, daß er nicht mehr annehmbar ist.Appropriate devices have already been proposed, however Their disadvantage is that of the compressor and / or the high pressure water pump generated noise of the highest degree is undesirable and the in many cases, especially in rooms or in buildings with a standard of living and in hospitals, canteens, offices etc., is even so large that it is no longer acceptable is.

Die Erfindung beruht auf der Einsicht, daß es möglich ist, den von der Vorrichtung erzeugten Lärmpegel erheblich zu senken, ohne zusätzliche Schalldämpfungseinrichtungen vorzusehen und ohne das Gewicht der Vorrichtung zu erhöhen oder teuere Schalldämpfungs- oder Schallabsorbierungsmaterialien zu verwenden, indem der Tank für das Reinigungsmittel zur Schallabsorption verwendet wird.The invention is based on the insight that it is possible that of the noise level generated by the device significantly, without additional soundproofing devices and without increasing the weight of the device or expensive soundproofing or to use sound absorbing materials by the tank for the detergent is used for sound absorption.

Zur Erfüllung dieses Zwecks ist die erfindungsgemäße Vorrichtung dadurch gekennzeichnet, daß der Drucktank gebildet ist von dem Raum zwischen den Wänden eines doppelwandigen Gebildes und daß das bzw. die lärmerzeugende(n) Element(e) innerhalb des Gebildes angeordnet ist bzw. sind Zusätzlich zu dem Schalldämpfungseffekt führt die größere Kompaktheit der Einrichtung auch zu einer Vorrichtung, die bequemer und zweckmäßiger zu handhaben ist.In order to achieve this purpose, the device according to the invention is thereby characterized in that the pressure tank is formed by the space between the walls a double-walled structure and that the noise-generating element (s) is arranged within the structure or are in addition to the soundproofing effect The greater compactness of the device also leads to a device that is more convenient and is more convenient to use.

Zur Gewährleistung einer geeigneten Bewegbarkeit der Vorrichtung ist diese im allgemeinen auf einem auf Rädern laufenden Fahrgestell angeordnet Obwohl ein den Bedürfnissen entsprechendes Gebilde der Vorrichtung jede beliebige Gestalt besitzen kann, vorausgesetzt, daß dieses Gebilde die lärmerzeugenden Elemente umschließt, wird eine zylindrische Gestalt aus Gründen der Zugänglichkeit zu den inneren Teilen und der Stabilität und Gestaltung bevorzugt.To ensure suitable mobility of the device is these are generally arranged on a chassis running on wheels, Though a structure of the device corresponding to the needs of any desired shape can own, provided that this structure encloses the noise-producing elements, becomes a cylindrical shape for the sake of accessibility to the internal parts and the stability and design preferred.

Zur Vergrößerung der mechanischen Stabilität der Innenwand eines derartigen Zylinders ist diese Wand an ihrer Innenseite bevorzugterweise mit radial vorstehenden Rippen ausgestattet.To increase the mechanical stability of the inner wall of such a Cylinder, this wall is preferably radially protruding on its inside Ribs fitted.

In bevorzugter Weise sind diese Rippen in das Material der Innenwand durch Falten eingeformt.These ribs are preferably made in the material of the inner wall molded by folding.

Zur Ermöglichung der Entfernung der lärmerzeugenden Einheit aus dem Inneren des Tanks zu Instandhaltungs-,Reparatur-und anderweitigen Zwecken ist die lärmerzeugende Einheit in vorteilhafter Weise auf einem Schlitten angeordnet.To enable the noise generating unit to be removed from the Inside the tank for maintenance, repair and other purposes is the Noise-generating unit arranged in an advantageous manner on a slide.

Ein derzeit übliches Beispiel für ein lärmerzeugendes Element ist insbesondere ein Kompressor, der erforderlich ist, um die Verwendung der Vorrichtung auch in solchen Räumen zu ermöglichen, in denen keine Druckluftleitungen vorhanden sind.A currently common example of a noise generating element is in particular a compressor that is required to use the device to enable even in those rooms in which no compressed air lines are available are.

Die durch Verwendung der erfindungsgemäßen Vorrichtung erreichte Absenkung des Lärmpegels kann mittels der Ergebnisse des nachfolgenden Versuches erläutert werden.The lowering achieved by using the device according to the invention the noise level can be explained using the results of the following experiment will.

Bei diesem Versuch wurden die Schallpegel mit einem üblichen Kompressor verglichen, der bei einer Sprühvorrichtung für ein Schaumreinigungsmittel der beschriebenen Art verwendet wird: I) Ohne Anordnung des Kompressors in dem zylindrischen Drucktank, II) mit Anordnung des Kompressors in dem Zylinder.In this experiment, the sound levels were measured using a conventional compressor compared that in a spray device for a foam detergent of the described Type is used: I) Without placing the compressor in the cylindrical pressure tank, II) with the arrangement of the compressor in the cylinder.

Die in einem Abstand von 0,5 m ohne Drucktank gemessenen Werte wurden auf 100 % angesetzt; die übrigen gemessenen Werte sind jeweils in Prozenten des Ausgangswertes angegeben. Abstand (m) 0,5 1,0 1,5 Lärmpegel mit Kompressor außerhalb des Tanks 100% 90% 75% Lärmpegel mit Kompressor innerhalb des Tanks 75% 60% 40% Im folgenden wird die Erfindung unter Bezugnahme auf die Zeichnungen weiter ins einzelne gehend erläutert; in diesen zeigt: Fig. 1 eine schematische Vorderansicht der erfindungsgemäßen Vorrichtung und Fig. 2 eine schematische Seitenansicht der erfindungsgemäßen Vorrichtung.The values measured at a distance of 0.5 m without a pressure tank were set to 100%; the other measured values are given as a percentage of the initial value. Distance (m) 0.5 1.0 1.5 Noise level with compressor outside the tank 100% 90% 75% Noise level with compressor inside the tank 75% 60% 40% In the following the invention is explained in more detail with reference to the drawings; 1 shows a schematic front view of the device according to the invention and FIG. 2 shows a schematic side view of the device according to the invention.
