Description

Die vorliegende Erfindung bezieht sich auf eine Einrichtung zur portionenweisen Bildung von Seifenschaum, bestehend aus einem Vorratsbehälter für eine wässerige Seifenlösung, mit je einer durch einen einzigen Hebel betätigbaren Seifenlösungs-Dosierpumpe und Druckluft-Membranpumpe mit Membrankolben und Rückwirkfeder sowie einer Mischkammer zur Schaumbildung.The present invention relates to a device for portion-wise formation of soap foam, consisting of a storage container for an aqueous soap solution, each with a soap solution metering pump which can be actuated by a single lever and compressed air membrane pump with membrane piston and reaction spring and a mixing chamber for foam formation.

Seifenspender finden bekanntlich in einer Vielzahl von Ausführungen Einsatz bei öffentlichen und privaten Waschgelegenheiten. Bekannt sind u.a. schaumbildende Seifenspender, welche ein Treibgas aus Dichlordifluormethan (Freon 12) verwenden und deren Verbreitung aus Umweltschutzgründen nur mit grosser Zurückhaltung erfolgen darf.As is well known, soap dispensers are used in a variety of designs for public and private washing facilities. Among others, are known Foam-forming soap dispensers, which use a propellant gas made of dichlorodifluoromethane (Freon 12) and whose distribution may only be carried out with great caution for environmental reasons.

Es ist ferner eine Einrichtung zur Dosierung und Bildung von Seifenschaum gemäss dem Oberbegriff des Patentanspruchs 1 bekannt (EPA - A1- 0019582), welche einen einzigen Hebel zum gleichzeitigen Antrieb eines Kolbens einer Seifenlösungs-Dosierpumpe und einer Membranpumpe zur Erzeugung von Druckluft aufweist. Über eine perforierte Wandung einer Leitung wird die Druckluft in die in einer Mischkammer befindliche, dosierte Menge Seifenlösung eingeblasen, wodurch ein grobblasiger Seifenschaum entsteht, welcher anschliessend durch einen porösen Körper durchgeblasen, homogenisiert und verdichtet wird.There is also known a device for metering and forming soap foam according to the preamble of claim 1 (EPA - A1- 0019582), which has a single lever for simultaneously driving a piston of a soap solution metering pump and a diaphragm pump for generating compressed air. The compressed air is blown into the metered quantity of soap solution in a mixing chamber via a perforated wall of a line, resulting in a coarse-bubble soap foam, which is then blown through a porous body, homogenized and compressed.

In praxi erweist sich diese Lösung als sehr ökonomisch in bezug auf den Seifenverbrauch. Es hat sich dagegen gezeigt, dass der Seifenschaum, insbesondere bei längerem Nichtgebrauch der Einrichtung, im Bereich seiner Austrittsöffnung eintrocknen kann, was sich funktionsstörend auf den Betrieb auswirkt.In practice, this solution proves to be very economical in terms of soap consumption. On the other hand, it has been shown that the soap foam, particularly when the device is not used for a long time, in the region of its outlet opening can dry out, which has a detrimental effect on operation.

Es ist daher Aufgabe der Erfindung, eine Einrichtung zur portionenweisen Bildung von Seifenschaum zu schaffen, welche auch nach längerem Nichtgebrauch sofort funktionsbereit ist.It is therefore an object of the invention to provide a device for the portionwise formation of soap foam, which is immediately ready for use even after a long period of non-use.

Diese Aufgabe wird durch das im Patentanspruch 1 gekennzeichnete Merkmal gelöst.This object is achieved by the feature characterized in claim 1.

Nachfolgende abhängige Ansprüche stellen vorteilhafte Weiterbildungen dieser Lösung dar.The following dependent claims represent advantageous developments of this solution.

Die Einrichtung nach Anspruch 2 ergibt ein impulsartiges Ausstossen der Seifenschaumportion und verhindert somit ein Verstopfen und/oder ein Nachtropfen nach dem Betätigen der Einrichtung.The device according to claim 2 results in a pulse-like ejection of the soap foam portion and thus prevents clogging and / or dripping after operating the device.

Als besonders zweckmässig hat sich eine Ventilanordnung nach Anspruch 3 erwiesen.A valve arrangement according to claim 3 has proven to be particularly useful.

Die Betriebssicherheit der Einrichtung und somit ihr Bereitstellungsgrad lässt sich durch Ventile entsprechend Anspruch 4 nochmals steigern.The operational reliability of the device and thus its level of availability can be increased further by valves in accordance with claim 4.

Die Ausgestaltung des doppeltwirkenden Kolbens in der Druckluft-Membranpumpe gemäss Anspruch 5 weist den Vorteil einer hohen Luftleistung trotz geringer Einbaumasse und hohem Bedienungskomfort auf.The design of the double-acting piston in the compressed air diaphragm pump according to claim 5 has the advantage of high air performance despite the small installation dimensions and high ease of use.

Nachfolgend soll anhand einer Zeichnung ein Ausführungsbeispiel des Erfindungsgegenstands dargestellt werden.An exemplary embodiment of the subject matter of the invention is to be illustrated below with the aid of a drawing.

Die Figur zeigt eine bevorzugte Ausführungsform eines gegenüber dem eingangs erwähnten, weiterentwickelten Seifenspenders in Schnittdarstellung.The figure shows a preferred embodiment of a soap dispenser developed in comparison to the aforementioned, in a sectional view.

In der Figur ist mit G das Gehäuse eines Seifenspenders bezeichnet. Aus dem Gehäuse G ragt ein Betätigungshebel 1 mit einem Handgriff 1'. Über dem Gehäuse G ist ein mit wässeriger Seifenlösung gefüllter Vorratsbehälter V - durch einen Pfeil symbolisiert - angeordnet. Ein Mundstück 67 reicht ins Gehäuse G und ist über eine seitliche Zuführung 6 mit einem Zylinderraum 4 einer Seifenlösungs-Dosierpumpe 3 verbunden. In der Seifenlösungs-Dosierpumpe 3 ist ein Kolben 2 mit einer zylindrischen Sacklochbohrung und einer Kolbenaustrittsöffnung 7' angeordnet. Dieser Kolben 2 ist schieberartig ausgebildet und einseitig mittels eines O-Rings 52 abgedichtet. Durch das aus dem Zylinderraum 4 herausragende Endteil des Kolbens 2 ist ein nicht dargestellter Lagerzapfen gesteckt, welcher auf seinen beiden Endseiten in einem Antriebsbügel 1a kraftschlüssig eingesetzt ist. Der Zylinderraum 4 ist über eine Verbindungsöffnung 7 mit einer Mischkammer 8 verbunden. In den unteren Teil der Mischkammer 8 ragt das nasenartig ausgebildete Ende einer Leitung 18, durch welches eine Druckluft D über eine Druckluft-Leitung 5 einströmt und über Löcher 19 austreten kann.In the figure, G denotes the housing of a soap dispenser. An actuating lever 1 with a handle 1 'protrudes from the housing G. Arranged above the housing G is a storage container V filled with an aqueous soap solution - symbolized by an arrow. A mouthpiece 67 extends into the housing G and is connected via a side feed 6 to a cylinder space 4 of a soap solution metering pump 3. A piston 2 with a cylindrical blind bore and a piston outlet opening 7 'is arranged in the soap solution metering pump 3. This piston 2 is designed like a slide and is sealed on one side by means of an O-ring 52. A bearing journal (not shown) is inserted through the end part of the piston 2 protruding from the cylinder space 4 and is inserted non-positively on its two end sides in a drive bracket 1a. The cylinder space 4 is connected to a mixing chamber 8 via a connection opening 7. In the lower part of the mixing chamber 8 protrudes the nose-like end of a line 18 through which a compressed air D flows in via a compressed air line 5 and can exit via holes 19.

Die Druckluft D wird durch Betätigen des Hebels 1 mittels einer Betätigungskraft F in einer Membranpumpe 9 erzeugt. Der Zylinder 13 dieser Membranpumpe 9 weist eine durch konkave Teile 14c und 14d geführte Membrane 14a aus Gummi auf, welche einen doppelwirkenden Membrankolben 14 bilden. Diese Membranhalterung ist durch 59 verschraubt. Eine Rückwirkfeder 12 ist um eine Kolbenstange 14b gelegt und drückt den Membrankolben 14 sowie die damit verbundenen Betätigungsorgane in die gezeichnete obere Lage.The compressed air D is generated by actuating the lever 1 by means of an actuating force F in a diaphragm pump 9. The cylinder 13 of this diaphragm pump 9 has a rubber diaphragm 14a which is guided through concave parts 14c and 14d and which form a double-acting diaphragm piston 14. This membrane holder is screwed through 59. A reaction spring 12 is placed around a piston rod 14b and presses the membrane piston 14 and the actuating elements connected to it into the drawn upper position.

Der Membrankolben 14 kann einen Hub H (nach unten) erfahren und zieht dabei Luft über einen Lufteintritt 56 und ein Klappenventil 55 in den Zylinder 13.The membrane piston 14 can experience a stroke H (downward) and in the process draws air into the cylinder 13 via an air inlet 56 and a flap valve 55.

Das Klappenventil 55 ist aus Gummi gefertigt und einseitig durch eine Halterung 57 im Deckel des Zylinders 13 fixiert.The flap valve 55 is made of rubber and fixed on one side by a holder 57 in the cover of the cylinder 13.

Gleichzeitig schliesst ein am Fuss der Membranpumpe 9 linksseitig befindliches Ventil 70; die unterhalb der Membrane 14a befindliche Luft D wird komprimiert und strömt über ein rechtsseitig der Kolbenstange 14b befindliches weiteres Ventil 70 in die Druckluft-Leitung 5.At the same time, a valve 70 on the left side at the foot of the diaphragm pump 9 closes; The air D located below the membrane 14a is compressed and flows into the compressed air line 5 via a further valve 70 located on the right side of the piston rod 14b.

Wird nun nicht mehr auf den Hebel 1 gedrückt, d.h. die Betätigungskraft F hört auf zu wirken, so bewegt sich der Membrankolben 14 relativ rasch unter dem Einfluss seiner Rückwirkfeder 12 in die obere, gezeichnete Lage. Dabei wird das Klappenventil 55 geschlossen und im Zylinderkopf die Druckluft D erzeugt, welche über die Druckluft-Leitung 5a, auf ein in den Verbindungskanälen angeordnetes, weiteres Ventil 70 wirkt, dieses öffnet und über die Leitung 5a in den oberen Teil der Austrittsöffnung A einströmt und den hier befindlichen Seifenschaum nahezu restlos ausbläst.Is no longer pressed on lever 1, i.e. the actuating force F ceases to act, the diaphragm piston 14 moves relatively quickly under the influence of its reaction spring 12 into the upper position shown. The flap valve 55 is closed and the compressed air D generated in the cylinder head, which acts via the compressed air line 5a, on a further valve 70 arranged in the connecting channels, opens it and flows via the line 5a into the upper part of the outlet opening A and almost completely blows out the soap foam here.

In der gezeichneten Ruhelage ist der Zylinderraum 4 bis auf einen kleinen, definierten Totraum 15, welcher im wesentlichen durch einen Sackraum 16 mit einer Verbindungsbohrung 16' vorbestimmt ist, mit Seifenlösung gefüllt.In the rest position shown, the cylinder space 4 is filled with soap solution except for a small, defined dead space 15, which is essentially predetermined by a sack space 16 with a connecting bore 16 '.

Wird jedoch der Betätigungshebel 1 gedrückt, so bewegt sich der schieberartige Kolben 2 bis ans Ende des Zylinderraumes 4 und erzeugt dabei mittels der im Totraum 15 und Sackraum 16 befindliche Luft ein Luftpolster 17, wodurch die Seifenlösung nun unter Druck steht und diese in der Endstellung des Kolbens 2 über die Kolbenaustrittsöffnung 7', die Verbindungsöffnung 7 und ein hierbei geöffnetes Klappenventil 54 in die Mischkammer 8 gepresst wird.However, if the actuating lever 1 is pressed, the slide-like piston 2 moves to the end of the cylinder space 4 and thereby generates an air cushion 17 by means of the air in the dead space 15 and sack space 16, as a result of which the soap solution is now under pressure and in the end position of the Col bens 2 is pressed into the mixing chamber 8 via the piston outlet opening 7 ', the connecting opening 7 and a flap valve 54 which is open in the process.

Jetzt strömt die Druckluft D in besagter Weise durch die Druckluft-Leitung 5, die Leitung 18, durch die Löcher 19 in die Mischkammer 8 ein und erzeugt dort einen grobblasigen Schaum, welcher durch einen porösen Körper 20, einer sogenannten Fritte, gepresst und homogenisiert wird und über einen nachfolgenden Expansionsraum 21 in einem Schaumumlenkkörper 22 schliesslich durch eine Austrittsöffnung A ausgestossen wird. Es steht hier ein feiner, walnussgrosser Seifenschaum für Reinigungszwecke zur Verfügung.The compressed air D now flows in the aforementioned manner through the compressed air line 5, the line 18, through the holes 19 into the mixing chamber 8 and produces a coarse-bubble foam there, which is pressed and homogenized by a porous body 20, a so-called frit and is finally expelled through an outlet opening A in a foam deflecting body 22 via a subsequent expansion space 21. There is a fine, walnut-sized soap foam available for cleaning purposes.

In dieser Einrichtung stehen die Achsen 10 und 11 der Kolben 2 und 14 einander senkrecht gegenüber. Die Kraftübertragung vom Hebel 1, welcher zweiarmig ausgeführt ist, erfolgt über Lagerzapfen auf einen Antriebsbügel 1a bzw. auf die Kolbenstange 14b. Das Klappventil 54 ist aus synthetischem Kautschuk gefertigt und durch einen teilweise umlaufenden Haltering 58 randseitig zentriert.In this device, the axes 10 and 11 of the pistons 2 and 14 are perpendicular to each other. The power transmission from the lever 1, which is designed with two arms, takes place via bearing journals on a drive bracket 1a or on the piston rod 14b. The flap valve 54 is made of synthetic rubber and centered on the edge side by a partially circumferential retaining ring 58.

Die Druckluft-Leitung 5a ist, in der Figur gestrichelt dargestellt, kreisförmig um einen Schraubzapfen 68 herumgeführt. Dieser Schraubzapfen 68 fixiert die zentral im Gehäuse G angeordneten Schaumumlenkkörper 22, porösen Körper 20 und Mischkammer 8.The compressed air line 5a, shown in dashed lines in the figure, is guided in a circle around a screw pin 68. This screw pin 68 fixes the foam deflection bodies 22, porous bodies 20 and mixing chamber 8 arranged centrally in the housing G.

Als Ventile 70 haben sich solche mit einem zylinderförmigen Ventilkörper 71 aus handelsüblichem Messing mit einer Ventilbüchse 73 und einem Ventilsitz 72 aus einem ebenfalls handelsüblichen hochmolekularen Formaldehyd-Polymerisat (Delrin) bewährt.Valves 70 with a cylindrical valve body 71 made of commercially available brass with a valve sleeve 73 and a valve seat 72 made of a commercially available high molecular weight formaldehyde polymer (Delrin) have also proven successful.

Der Erfindungsgegenstand lässt sich sehr universell einsetzen und stellt insbesondere durch seine fortwährende Betriebsbereitschaft und seine einfache reproduzierbare Handhabung einen Fortschritt in der Waschraumhygiene dar.The subject of the invention can be used very universally and, in particular due to its continuous operational readiness and its simple, reproducible handling, represents an advance in washroom hygiene.
