Description

Die Erfindung betrifft einen Schaumseifenspender mit einem Gehäuse mit einer unterseitigen Ausgabeöffnung, mit einer im Inneren des Gehäuses angeordneten Behälteraufnahme, in die austauschbar ein Vorrat mit flüssiger Seife einsetzbar und unterhalb der ein Seifenbehälter vorgesehen ist, mit einer Seifenpumpe für die Seife, mit einer Luftpumpe zum Zuführen von Schäumluft, und mit einer Schäumeinrichtung nahe der Ausgabeöffnung.The invention relates to a foam soap dispenser with a housing having a discharge opening on the underside, with a container receptacle arranged inside the housing, in which a supply of liquid soap can be used interchangeably and below which a soap container is provided, with a soap pump for the soap, with an air pump for Supplying foaming air, and with a foaming device near the discharge opening.

Derartige Schaumseifenspender mit getrennten Pumpen für Luft und Seife sind bereits bekannt, beispielsweise aus der WO 96/29921 , bei der zwei Kolbenpumpen mittels eines Betätigungselementes, das durch den schwenkbaren Deckel des Gehäuses gebildet ist, gemeinsam betätigt werden können.Such foam soap dispensers with separate pumps for air and soap are already known, for example from the WO 96/29921 in which two piston pumps can be operated together by means of an actuating element which is formed by the pivotable cover of the housing.

US 2005/139612 und WO 2005/107699 zeigen ebenfalls Spender mit Pumpen für Seife und Luft, die mittels eines Hebels gemeinsam und gleichzeitig händisch betätigt werden. Nach der US 2005/139612 kann dabei die Weglänge des Hebels und die Übersetzung zwischen dem Hebel und jedem Pumpenantriebsrad einzeln eingestellt werden. Nach der WO 2005/107699 kann als Alternative zur händischen Betätigung ein Sensor und ein davon abhängiger Antrieb vorhanden sein. US 2005/139612 and WO 2005/107699 also show dispensers with pumps for soap and air, which are operated by a lever together and simultaneously by hand. After US 2005/139612 can be set individually the path length of the lever and the ratio between the lever and each Pumpenantriebsrad. After WO 2005/107699 may be present as an alternative to manual operation, a sensor and a dependent drive.

Der Einfachheit halber wird hier und in den anliegenden Ansprüchen von "Schaumseife" und "Seife" gesprochen, worunter alle aufschäumbaren Mittel für Reinigung, Desinfektion, Pflege usw. zu verstehen sind.For simplicity, here and in the appended claims of "foam soap" and "soap" spoken, by which all foamable means for cleaning, disinfection, care, etc. are to be understood.

Die Erfindung hat es sich nun zur Aufgabe gestellt, einen berührungslos betätigbaren Schaumseifenspender zu schaffen und schlägt hiezu vor, dass die Luftpumpe als Membranpumpe und die Seifenpumpe als Schlauchquetschpumpe ausgebildet sind, und dass den beiden Pumpen getrennt antreibbare Elektromotore zugeordnet sind.The invention has now taken on the task of creating a contactless actuated foam soap dispenser and proposes for this purpose that the air pump are designed as a diaphragm pump and the soap pump as a peristaltic pump, and that the two pumps are assigned separately driven electric motors.

Eine Membranpumpe ist eine Maschine zur Förderung von Flüssigkeiten bzw. Gasen. Ihr Funktionsprinzip ähnelt der Kolbenpumpe, wobei jedoch das zu fördernde Medium durch eine Membran vom Antrieb getrennt ist. Durch diese Trennmembran ist somit der mechanische Teil des Antriebes von schädlichen Einflüssen des Fördermediums abgeschirmt. Der Antrieb erfolgt beispielsweise durch einen Elektromotor mittels an der Membran befestigter Pleuelstange. Derartige Membranpumpen sind in kleiner Bauweise als sogenannte Mikropumpen erhältlich, die beispielsweise in einem kompakten L-förmigen Gehäuse angeordnet sind, in dem Auslass und Einlass zueinander und zur Motorachse parallel ausgerichtet sind.A diaphragm pump is a machine for conveying liquids or gases. Their function is similar to the piston pump, but the medium to be pumped is separated by a membrane from the drive. By this separation membrane thus the mechanical part of the drive is shielded from harmful influences of the pumped medium. The drive takes place, for example, by an electric motor by means of a connecting rod attached to the diaphragm. Such diaphragm pumps are smaller in size Construction available as a so-called micropumps, which are arranged for example in a compact L-shaped housing, are aligned in the outlet and inlet to each other and to the motor axis in parallel.

Für dickflüssige Substanzen, wie z.B. Seife, eignet sich eine Schlauchquetschpumpe besser, da sie unempfindlich gegen Lufteinschlüsse ist und die Abgabe der entsprechenden Portion Seife sicherstellt. Der Pumpenrotor trägt zumindest zwei, am Umfang vorstehende Walzen, die einen entlang des Rotorumfangs gekrümmten Schlauch quetschen. Der Antrieb erfolgt insbesondere ebenfalls durch einen Elektromotor.For viscous substances, such as Soap, a peristaltic pump is better, because it is insensitive to air bubbles and ensures the delivery of the appropriate portion of soap. The pump rotor carries at least two circumferentially protruding rollers which squeeze a tube curved along the circumference of the rotor. The drive is in particular also by an electric motor.

Der Schaumseifenspender ist für die berührungslose Abgabe bevorzugt mit einer Sensoreinrichtung in der Umgebung der Ausgabeöffnung versehen, mittels der eine untergehaltene Hand erkannt und die beiden Pumpen zur Erzeugung einer Portion geschäumter Seife in Betrieb gesetzt werden.The foam soap dispenser is preferably provided for contactless dispensing with a sensor device in the vicinity of the dispensing opening, by means of which a hand is detected and the two pumps are put into operation to produce a portion of foamed soap.

Eine bevorzugte Ausführung sieht vor, dass der Behälter, die beiden Pumpen einschließlich der Elektromotoren, die Schäumeinrichtung und vorzugsweise eine Steuerung in einem Arbeitsblock zusammen gefasst sind, der als kompakter Bauteil im unteren Bereich des Spendergehäuses vorgesehen ist. Der Arbeitsblock umfasst einen vorzugsweise aus Kunststoff gefertigten Formteil mit einer oberen und einer unteren Ausnehmung. In der oberen Ausnehmung ist der Seifen behälter vorgesehen und in die untere Ausnehmung sind die beiden Pumpen und die Schäumeinrichtung eingesetzt. Dabei ist in einer bevorzugten Ausführung vorgesehen, dass die Schäumeinrichtung mittels eines Clips oder ähnlicher Steckvorrichtung leicht auswechselbar im Arbeitsblock gehalten ist, um etwa Schäumeinrichtungen mit unterschiedlichen Siebeinsätzen oder Aufschäumkörpern nach Bedarf verwenden zu können.A preferred embodiment provides that the container, the two pumps including the electric motors, the foaming device and preferably a controller are combined in a working block which is provided as a compact component in the lower region of the dispenser housing. The work block comprises a molded part preferably made of plastic with an upper and a lower recess. In the upper recess of the soap container is provided and in the lower recess, the two pumps and the foaming device are used. It is provided in a preferred embodiment that the foaming device by means of a clip or similar plug-in device is easily interchangeable held in the work block to use as foaming devices with different Siebeinsätzen or Aufschäumkörpern as needed.

In einer weiteren bevorzugten Ausführung ist vorgesehen, dass mittels der Steuerung das Verhältnis der Fördervolumina von Luft und Seife durch Änderung der Drehzahl einer der beiden Elektromotoren einstellbar ist. Insbesondere werden daher Gleichstrommotoren verwendet, deren Drehzahl und damit direkt verbundene Fördermenge direkt proportional zur Motorspannung ist.In a further preferred embodiment, it is provided that by means of the control, the ratio of the delivery volumes of air and soap by adjusting the speed of one of the two electric motors is adjustable. In particular, therefore, DC motors are used whose speed and thus directly connected flow rate is directly proportional to the motor voltage.

Die Veränderung der Schaumkonsistenz ermöglicht es einerseits, eine festgesetzte Mindestabgabemenge, beispielsweise einer desinfizierenden Reinigungsflüssigkeit, einzustellen, oder andererseits, bei starker Beschmutzung eine höhere Menge bzw. bei leichter Beschmutzung eine Mindermenge an Seifenschaum zur Verfügung zu stellen, und dabei jeweils die Abgabeportion und die Abgabezeit nahezu unverändert zu belassen.The change in the foam consistency makes it possible, on the one hand, to set a stipulated minimum delivery quantity, for example a disinfecting cleaning liquid, or, on the other hand, to provide a high level of heavy soiling or, if lightly soiled, a lesser amount of soap scum, leaving the dispensing portion and dispensing time virtually unchanged.

In einer bevorzugten Ausführung ist daher vorgesehen, dass das Volumenverhältnis durch Änderung der Drehzahl des Motors der Seifenpumpe einstellbar ist. Die Drehzahl des Motors der Luftpumpe bleibt in dieser Ausführung somit konstant. Bevorzugte Volumenverhältnisse von Luft zu Seife sind zwischen 50:1 - ziemlich trockener, feinstporiger Schaum - bis 50:2 (= 25:1) also mit doppeltem Seifenanteil, wodurch der Schaum ziemlich fließfähig ist. Bevorzugte Abgabemengen an aufgeschäumter Reinigungsflüssigkeit sind ca. 0,3 ml bei 1 Sekunde und einem annähernden Volumenverhältnis von 50:1 - ziemlich trockener Schaum - bis ca. 0,9 ml bei 1,5 Sekunden und einem annähernden Volumenverhältnis von 50:2 - sehr feuchter Schaum. Das Fördervolumen der Luftpumpe kann bevorzugt 15 ml/sec betragen.In a preferred embodiment it is therefore provided that the volume ratio can be adjusted by changing the rotational speed of the motor of the soap pump. The speed of the motor of the air pump remains constant in this embodiment. Preferred volume ratios of air to soap are between 50: 1 - fairly dry, fine-pored foam - to 50: 2 (= 25: 1) so with double soap content, whereby the foam is quite fluid. Preferred delivery rates of foamed cleaning fluid are about 0.3 ml at 1 second and an approximate volume ratio of 50: 1 - fairly dry foam - to about 0.9 ml at 1.5 seconds and an approximate volume ratio of 50: 2 - very damp foam. The delivery volume of the air pump may preferably be 15 ml / sec.

Ein Seifenschaumspender weist ein Gehäuse 21 mit einer Abdeckung auf, in dessen oberen Bereich ein Vorrat 23 in eine flüssigkeitsdichte Aufnahme 20 austauschbar eingesetzt ist. Im unteren Bereich ist ein kompakter Arbeitsblock 1 vorgesehen, in dem alle für die Funktion erforderlichen Elemente zusammengefasst sind. Schematisch dargestellt enthält, wie Fig. 2 zeigt, der Arbeitsblock 1 einen Seifenbehälter 2, aus dem eine Seifenpumpe 5, die als Schlauchquetschpumpe ausgebildet ist, Seife ansaugt und über eine Seifenleitung 4 einer Schäumeinrichtung 3 zuführt.A soap foam dispenser has a housing 21 with a cover, in the upper region of a supply 23 is inserted into a liquid-tight receptacle 20 replaceable. In the lower area a compact working block 1 is provided, in which all elements required for the function are combined. Schematically illustrated how Fig. 2 shows, the working block 1 a soap container 2, from which a soap pump 5, which is designed as a peristaltic pump sucks soap and a soap line 4 a foaming device 3 feeds.

Der Arbeitsblock 1 enthält weiters eine Luftpumpe 7, die als Membranpumpe ausgebildet ist, Luft ansaugt und über eine Luftleitung 6 ebenfalls der Schäumeinrichtung 3 zuführt. Eine Betätigungseinrichtung 8 ermöglicht die Änderung verschiedener Parameter, wie Größe der Schaumportion 10, Luft-Seifen-Verhältnis etc. Die verwendeten Pumpen weisen jeweils einen elektrischen Antrieb, insbesondere einen Gleichstrommotor auf, dessen Drehzahl direkt proportional zur Motorspannung ist. Wie Fig. 3 zeigt, ist an einer Motorabtriebswelle 11 eine Exzenterscheibe 12 befestigt, die einen federbeaufschlagten Hubkolben 13 hin- und herbewegt. Der Hubkolben 13 ragt in das Pumpengehäuse und ist mit einer Membran 14 verbunden, die zwischen zwei Gehäuseteilen gedichtet eingespannt ist und eine Pumpenkammer 17 begrenzt. Die Pumpenkammer 17 weist einen Einlass 15 und einen Auslass 19 auf, denen jeweils ein Rückschlagventil 16 und 18 zugeordnet ist. Fig. 3 zeigt die Auspress- bzw. Druckstellung der Luftpumpe 7, in der das einlassseitige Ventil 16 geschlossen und das auslassseitige Ventil 18 geöffnet ist.The working block 1 further includes an air pump 7, which is designed as a diaphragm pump, sucks in air and also via an air line 6 of the foaming device 3 feeds. An actuator 8 allows the change of various parameters, such as size of the foam portion 10, air-soap ratio, etc. The pumps used each have an electric drive, in particular a DC motor whose speed is directly proportional to the motor voltage. As Fig. 3 shows, an eccentric 12 is fixed to a motor output shaft 11, which reciprocates a spring-loaded reciprocating piston 13. The reciprocating piston 13 protrudes into the pump housing and is connected to a diaphragm 14, which is clamped sealed between two housing parts and a pump chamber 17 limited. The pump chamber 17 has an inlet 15 and an outlet 19, to each of which a check valve 16 and 18 is assigned. Fig. 3 shows the Auspress- or pressure position of the air pump 7, in which the inlet-side valve 16 is closed and the outlet-side valve 18 is opened.

Der Arbeitsblock 1 enthält weiters eine in Fig. 4 schematisch dargestellte Schlauchquetschpumpe. An einer Abtriebswelle 25 ist ein Rotor 26 befestigt, an dem zwei oder drei über den Umfang vorstehende Rollen bzw. Wälzkörper 27 drehbar gelagert sind. Etwa im Halbkreis ist um den Rotor ein Schlauch 28 angeordnet, der von den Rollen 27 bei Drehung des Rotors 26 so gequetscht wird, dass im Schlauch 28 enthaltene Seife vom Einlass 29 zum Auslass 30 gefördert wird. Eine derartige Schlauchquetschpumpe ist selbstansaugend und wird durch eingeschlossene Luft in ihrer Förderwirkung nicht beeinträchtigt, sodass sie sich zur gleichmäßigen Dosierung von Seifenportionen gut eignet.The work block 1 further contains an in Fig. 4 schematically shown peristaltic pump. On an output shaft 25, a rotor 26 is fixed, are rotatably mounted on the two or three projecting over the circumference rollers or rolling elements 27. Approximately in a semicircle, a hose 28 is arranged around the rotor, which is squeezed by the rollers 27 upon rotation of the rotor 26 so that soap contained in the hose 28 is conveyed from the inlet 29 to the outlet 30. Such a peristaltic pump is self-priming and is not affected by trapped air in their conveying effect, so it is well suited for the uniform dosage of soap servings.

Fig. 5 zeigt eine Ansicht schräg von unten in den Arbeitsblock 1. Der Arbeitsblock weist einen aus Kunststoff gefertigten Formteil auf, an dessen Oberseite der Seifenbehälter vorgesehen ist, der mit einem die Aufnahme 20 tragenden Deckel verschlossen ist. An der Unterseite sind Ausnehmungen für die Luftpumpe 7, die Seifenpumpe 5, die Schäumeinrichtung 3 und eine nicht gezeigte Steuerungsplatine vorgesehen. Vom Auslass 19 der Luftpumpe 7 und vom Auslass 30 der Seifenpumpe 5 führt jeweils ein Schlauch zur Schäumeinrichtung 3, wobei der Luftkanal mit 6 und der Seifenkanal mit 4 beziffert sind. Der Einlass 29 der Seifenpumpe 5 ist durch einen weiteren Schlauch 31 mit dem oberseitigen Seifenbehälter 2 verbunden. Die Schäumeinrichtung 3 ist durch einen U-förmigen Steckbügel 32 austauschbar am Arbeitsblock 1 vorgesehen. Fig. 5 shows a view obliquely from below into the working block 1. The work block has a molded plastic part, on top of which the soap container is provided, which is closed with a receptacle 20 carrying the lid. On the underside recesses for the air pump 7, the soap pump 5, the foaming device 3 and a control board, not shown, are provided. From the outlet 19 of the air pump 7 and the outlet 30 of the soap pump 5, a hose leads to the foaming device 3, wherein the air duct with 6 and the soap duct with 4 are numbered. The inlet 29 of the soap pump 5 is connected by a further hose 31 to the upper-side soap container 2. The foaming device 3 is provided interchangeably on the working block 1 by means of a U-shaped plug-in bracket 32.

Die Luftfördermenge wird konstant gehalten, das heißt, die Drehzahl der Luftpumpe 7 wird nicht geändert. Der Seifenanteil, der die Konsistenz des Schaums beeinflusst, kann durch die Änderung der Drehzahl der Seifenpumpe 5 variiert werden.The air flow rate is kept constant, that is, the rotational speed of the air pump 7 is not changed. The proportion of soap that affects the consistency of the foam can be varied by changing the speed of the soap pump 5.

In Fig. 2 ist die Drehzahlregelung der Seifenpumpe 5 von außerhalb des Gehäuses 21 gezeigt. Der Drehknopf des Potentiometers /der Betätigungseinrichtung 8 kann aber auch im Gehäuseinneren angeordnet sein, wie in Fig. 1 angedeutet ist, wobei ein gegebenenfalls versperrter Gehäusedeckel geöffnet werden muss. Diese Ausführung erlaubt die Änderung der Seifenschaumkonsistenz nur befugten Benützern, beispielsweise dem Servicepersonal.In Fig. 2 the speed control of the soap pump 5 is shown from outside the housing 21. The knob of the potentiometer / the actuator 8 may also be arranged inside the housing, as in Fig. 1 is indicated, with an optionally obstructed housing cover must be opened. This design allows the change of soap scum consistency only to authorized users, such as service personnel.

Der Spender kann an das örtliche Stromnetz angeschlossen sein oder eine interne Stromquelle aufweisen. Bei einer internen Stromquelle, beispielsweise vier Alkaline-Batterien, sinkt die Batteriespannung mit fortschreitender Verwendung von 6,4 V auf 4 V ab. Einer internen Stromquelle ist daher insbesondere eine Spannungsstabilisierung mittels Pulsweitenmodulation zugeordnet (Fig. 6) und es werden Gleichstrommotoren verwendet, deren Motorspannung nahe der unteren Grenze der Batteriespannung angesiedelt ist, sodass die vorgegebenen Drehzahlen der beiden Pumpen fast bis zum Aufbrauch der internen Stromquelle gehalten werden können. Wie Fig. 6 zeigt, vergleicht ein Kontroller µC die Versorgungsspannung mit der Referenzspannung UREF einer Referenzdiode - kann auch eine interne Referenz sein - und regelt die Pulsweitenmodulation (PWM) des Motors M auf 4 V. Ein Ausgangstransistor T1 dient als Treiber, um den nötigen Strom für den Motor zu erreichen.The dispenser may be connected to the local power grid or have an internal power source. With an internal power source, such as four alkaline batteries, the battery voltage drops from 6.4V to 4V as the usage progresses. An internal current source is therefore in particular assigned a voltage stabilization by means of pulse width modulation ( Fig. 6 ) and DC motors are used, whose motor voltage is located near the lower limit of the battery voltage, so that the predetermined speeds of the two pumps can be maintained almost to the exhaustion of the internal power source. As Fig. 6 shows, a controller μC compares the supply voltage with the reference voltage U REF a reference diode - can also be an internal reference - and controls the pulse width modulation (PWM) of the motor M to 4 V. An output transistor T1 serves as a driver to provide the necessary current for the To reach the engine.
