Description

Die Erfindung bezieht sich auf ein Handgerät zum Reinigen verstopfter Abflüsse, mit einer Handpumpe aus einem rohrförmigen Pumpengehäuse, einem darin mittels einer rohrförmigen Kolbenstange verschiebbaren abgedichteten Kolben, einer die aus dem Pumpengehäuse an einem Längenende austretenden und einen Handgriff zeigende Kolbenstange umfassende, auf dem Pumpengehäuse festgelegten und einer an einem Verbindungsstutzen am anderen Pumpengehäuse-Längenende befestigten, elastischen Saugglocke.The invention relates to a hand-held device for cleaning clogged drains, comprising a hand pump comprising a tubular pump housing, a sealed piston displaceable therein by means of a tubular piston rod, and a piston rod that emerges from the pump housing at one end of the length and shows a handle and is fixed on the pump housing and an elastic suction bell attached to a connecting piece at the other end of the pump housing length.

Derartig aufgebaute pumpenförmige Handgeräte sind aus den US-PSen 4 186 451 und 2 129 415 bekannt geworden.Pump-shaped handheld devices constructed in this way are known from US Pat. Nos. 4,186,451 and 2,129,415.

Dabei arbeitet die sanitäre Kunststoffpumpe nach der US-PS 4 186 451 mit Saug- und Druckwirkung durch auf- und niedergehendes Verschieben des Kolbens im Pumpengehäuse, wobei die Verstopfungen mit dem Wasser zuerst aus dem Abfluß heraus in das Pumpengehäuse gesaugt und dann wieder zurück in den Abfluß gedrückt werden sollen.The sanitary plastic pump works according to US Pat. No. 4,186,451 with suction and pressure action by moving the piston in the pump housing up and down, whereby the blockages with the water are first sucked out of the drain into the pump housing and then back into the pump housing Drain should be pressed.

Bei stärkeren Verstopfungen kann in dem Pumpengehäuse durch den lediglich abgedichteten, aber in sich starren Kolben keine allmähliche und einstellbare Saugwirkung erzeugt werden, sondern der Kolben würde nach Art einer Luftpumpe blockiert und die Wirkungsweise der Pumpe unterbrochen.In the case of severe blockages, the only sealed but rigid piston in the pump housing cannot produce a gradual and adjustable suction effect, but the piston would be blocked like an air pump and the operation of the pump would be interrupted.

Die Saugpumpe nach der US-PS 2 129 415 arbeitet mit Saug-Druckwirkung durch Klappensteuerung innerhalb der Saugglocke und in einem oberhalb der Saugglocke angeordneten seitlichen Auslaufstutzen.The suction pump according to US Pat. No. 2,129,415 works with suction-pressure action by means of flap control within the suction bell and in a lateral outlet nozzle arranged above the suction bell.

Auch hier kann eine Blockierung des Kolbens bei starker Verstopfung und somit eine Unterbrechung der Saugwirkung entstehen.Here, too, the piston can become blocked in the event of severe blockage and thus an interruption of the suction effect.

Diese bekannten Pumpen zeigen den Nachteil einer individuellen Einstellung der Saug- und Druckkraft auf die vorhandenen Umstände in den Abflüssen.These known pumps show the disadvantage of an individual adjustment of the suction and pressure force to the existing circumstances in the drains.

Deshalb ist es Aufgabe der Erfindung, ein pumpenförmiges Reinigungsgerät nach der eingangs genannten Art dahingehend zu verbessern, daß die Saug- und Druckwirkung auf die gegebenen Umstände der Verstopfungen einstellbar und umstellbar ist, was durch einfache, sicher wirkende und selbsttätig funktionelle sowie von außen leicht bedienbare Mittel im Bereich des Kolbens und zwischen Pumpengehäuse und Kolben ermöglicht werden soll, so daß das Reinigungsgerät in der Arbeitsweise erheblich verbessert wird.Therefore, it is an object of the invention to improve a pump-shaped cleaning device according to the type mentioned in such a way that the suction and pressure effect on the given circumstances of the blockages is adjustable and convertible, which is simple, safe-acting and automatically functional and easy to use from the outside Means in the area of the piston and between the pump housing and piston should be made possible, so that the cleaning device is significantly improved in its operation.

Diese Aufgabe wird erfindungsgemäß durch die kennzeichnenden Merkmale des Patentanspruches 1 gelöst; die Merkmale der Ansprüche 2 bis 4 stellen vorteilhafte Weiterbildungen der Aufgabenlösung dar.This object is achieved by the characterizing features of claim 1; the features of claims 2 to 4 represent advantageous developments of the task solution.

Durch die besondere Gestaltung des Kolbens mit Durchbrüchen, einer oben- und einer untenseitigen Flatterdichtung und Einstellung der unteren Flatterdichtung in eine Saug- und Druckstellung kann das erfindungsgemäße Handgerät wahlweise und entsprechend den Abfluß-Verstopfungen in eine mit einer Saug- und einer Druckkraft arbeitende Wirkung und in der Saug- und Druckkraftstärke eingestellt werden, wobei die Um- bzw. Einstellung bequem von außen möglich ist.Due to the special design of the piston with breakthroughs, a top and a bottom flutter seal and setting the lower flutter seal in a suction and pressure position, the handheld device according to the invention can optionally and according to the drainage blockages in a working with a suction and a pressure force and can be set in the suction and pressure force strength, whereby the change or adjustment is easily possible from the outside.

Die weiterhin im Verbindungsbereich zwischen Pumpengehäuse und Saugloch auf Saug- und Druckwirkung einstellbare Flatterdichtung trägt zur einwandfreien Wirkungsweise bei, da hierdurch auch die in das Pumpengehäuse eingesaugten Verstopfungen mit Wasser bei Kolben-Druckwirkung durch den Kolben hindurch nach oben zum Auslaufstutzen zum Abführen gebracht werden.The flap seal, which can also be adjusted in the connection area between the pump housing and suction hole for suction and pressure effects, contributes to the flawless operation, since this also causes the blockages sucked into the pump housing with water when the piston is under pressure through the piston upwards to the outlet nozzle for discharge.

Dieses pumpenförmige Handgerät ermöglicht die Erzeugung eines hohen Vakuumes zum Lösen und Ansaugen der Verstopfungen und ein sauberes Abführen derselben aus dem Handgerät heraus, was durch die automatisch wirkenden und einstellbaren Dichtungen bei geringem Kraftaufwand durch die Bedienungsperson möglich ist.This pump-shaped hand-held device enables the generation of a high vacuum for loosening and suctioning the blockages and a clean removal of them from the hand-held device, which is possible due to the automatically acting and adjustable seals with little effort by the operator.

An exemplary embodiment according to the invention is explained in more detail below with reference to the drawings. It shows:
  • 1 is a perspective view of a handheld device for cleaning clogged drains, shown in use,
  • 2 shows a longitudinal section through the same hand-held device with housing, piston and suction bell,
  • 3 shows a longitudinal section through a partial region of the housing with a seal which can be set into a suction and a pressure position,
  • 4 shows a longitudinal section through a partial area of the housing with piston and seals provided on both sides thereof, in the pressure position,

Das Handgerät zum Reinigen verstopfter Abflüsse setzt sich aus einer Handpumpe 1 und einer daran angeordneten Saugglocke 2 aus einem elastischen Werkstoff, wie Gummi, Kunststoff od. dgl. zusammen. Die Handpumpe 1 hat ein rohrförmiges Gehäuse 3 mit kreisförmigem Quer-Querschnitt, welches an einem (dem oberen) Ende durch eine aufgesetzte Kappe 4 verschlossen ist und am anderen (dem unteren) Ende einen aufgesetzten Verbindungsstutzen 5 hat, an dem die Saugglocke 2 durch Verschraubung 6 (Außengewinde am Verbindungsstutzen 5 und Innengewinde an einem an der Saugglocke 2 angeformten Anschlußstutzen 2a) befestigt ist.The hand-held device for cleaning clogged drains is composed of a hand pump 1 and an attached suction bell 2 made of an elastic material such as rubber, plastic or the like. The hand pump 1 has a tubular housing 3 with a circular cross-section, which is closed at one (the upper) end by an attached cap 4 and at the other (the lower) end has an attached connecting piece 5, on which the suction bell 2 by screwing 6 (external thread on the connecting piece 5 and internal thread on a molded on the suction bell 2 connecting piece 2a) is attached.

In dem Gehäuse 3 der Handpumpe 1 ist eine rohrförmige Kolbenstange 7 verschiebbar vorgesehen, die an ihrem saugglockenseitigen Längenende einen Kolben 8 mit randseitig umlaufender und an dem Gehäuse 3 innenseitig anliegender Dichtung 9 aufweist und die mit ihrem anderen Längenende durch die Kappe 4 abgedichtet aus dem Gehäuse 3 herausragt und an diesem außenliegenden Längenende einen Handgriff 10 trägt, der über eine Verbindungsbuchse 11 mit der Kolbenstange 7 verbunden ist.In the housing 3 of the hand pump 1, a tubular piston rod 7 is slidably provided, which has at its suction end on the suction bell side a piston 8 with a peripheral circumferential seal 9 lying on the inside of the housing 3 and with its other end of the length sealed by the cap 4 from the housing 3 protrudes and carries a handle 10 at this outer length end, which is connected to the piston rod 7 via a connecting bush 11.

Der Kolben 8 ist mit mehreren um die Kolbenstange 7 herum angeordneten Durchbrüchen (Löchern) 12 ausgestattet, durch die beim Verschieben der Kolbenstange 7 nach unten hin Luft nach oben und in den Raum 13 zwischen Kolbenstange 7 und Gehäuse 3 strömen kann.The piston 8 is equipped with a plurality of openings (holes) 12 arranged around the piston rod 7, through which air moves upwards and downwards when the piston rod 7 is displaced can flow into the space 13 between the piston rod 7 and the housing 3.

Auf der Oberseite des Kolbens 8 ist eine Dichtungsscheibe 17 als Flatterdichtung angeordnet, die die Durchbrüche 12 im Kolben 8 überdeckt. In der rohrförmigen Kolbenstange 7 ist eine Einstellstange 18 angeordnet, die den Kolben 8 durchgreift und an ihrem unteren, aus dem Kolben 8 nach unten herausragenden Ende eine Dichtungsscheibe 19 als Flatterdichtung trägt; diese Dichtungsscheibe 19 ist in ihrer Grundformgröße dem Innenquerschnitt des Gehäuses 3 angepaßt.On the top of the piston 8, a sealing washer 17 is arranged as a flutter seal, which covers the openings 12 in the piston 8. In the tubular piston rod 7 there is an adjusting rod 18 which extends through the piston 8 and carries a sealing washer 19 as a flap seal at its lower end which projects downward from the piston 8; this sealing washer 19 is adapted in its basic shape size to the inner cross section of the housing 3.

Mit ihrem oberen Ende greift die Einstellstange 18 durch die Verbindungsbuchse 11 hindurch und ist mit einem Rast- oder Hebelverschluß 20 verbunden, der eine Längsverschiebung der Einstellstange 18 und somit eine Einstellung der Dichtungsscheibe 19 gegenüber der Kolben-Unterseite in eine Saug- und eine Druckstellung ermöglicht. Die eingestellte Einstellstange 18 wird bei der Kolbenstangen-Verschiebung immer mit verschoben; beide (7,18) bilden also eine Verschiebeeinheit.With its upper end, the adjusting rod 18 extends through the connecting bush 11 and is connected to a latch or lever lock 20, which enables a longitudinal displacement of the adjusting rod 18 and thus an adjustment of the sealing washer 19 relative to the underside of the piston into a suction and a pressure position . The set adjusting rod 18 is always moved with the piston rod displacement; both (7.18) thus form a displacement unit.

In dem Verbindungsstutzen 5 ist auf einer Abstufung 5a eine den inneren Stutzen-Querschnitt überdeckende Dichtungsscheibe 21 als Flatterdichtung angeordnet, die mit einem Randbereich zwischen Gehäuse 3 und Abstufung 5a festgeklemmt ist und mit ihrem anderen Randbereich freiliegt. Diese Dichtungsscheibe 21 ist in eine Saug- und eine Druckstellung einstellbar, wobei an dem freiliegenden Randbereich ein flexibles Zugglied 22, wie Draht, Kunststoffschnur od. dgl. befestigt ist, welches seitlich nach außen aus dem Gehäuse 3 herausgeführt und dort mit einem am Gehäuse 3 vorgesehenen Rast- oder Hebelverschluß 23 verbunden ist.In the connecting piece 5, a sealing washer 21, which covers the inner cross-section of the connecting piece, is arranged on a step 5a as a flutter seal, which is clamped with an edge area between the housing 3 and step 5a and is exposed with its other edge area. This sealing washer 21 can be set in a suction and a pressure position, a flexible tension member 22, such as wire, plastic cord or the like, being attached to the exposed edge area, which is guided laterally outwards from the housing 3 and there with a on the housing 3 provided snap or lever lock 23 is connected.

In Fig. 2 befindet sich die Dichtungsscheibe 21 in der Saugstellung und liegt auf der Abstufung 5a auf. Über das Zugglied 22 und den Rast- oder Hebelverschluß 23 kann die Dichtungsscheibe 21 mit ihrem freiliegenden Randbereich nach oben hochgezogen werden in eine den Innenquerschnitt des Verbindüngsstutzens 5 freigebende Druckstellung, wie in Fig. 3 gezeigt.2, the sealing washer 21 is in the suction position and lies on the step 5a. Via the tension member 22 and the latch or lever lock 23, the sealing disk 21 with its exposed edge area can be pulled up into a pressure position releasing the inner cross section of the connecting piece 5, as shown in FIG. 3.

Es ist bevorzugt, an den Auslaufstutzen 14 einen flexiblen Schlauch 15 anzusetzen, der etwa die Länge der Handpumpe 1 hat und dann nach unten in den Bereich des Abflusses eines Waschbeckens 16 od. dgl. hängt, so daß die Flüssigkeiten und Schmutzteilchen nach unten zurückgeführt werden, wie in Fig. 1 dargestellt.It is preferred to attach a flexible hose 15 to the outlet connection 14, which has approximately the length of the hand pump 1 and then hangs down into the region of the drain of a wash basin 16 or the like, so that the liquids and dirt particles are returned downwards , as shown in Fig. 1.

Zum Reinigen eines verstopften Abflusses wird das Handgerät mit seiner Saugglocke 2 auf die Abflußöffnung aufgesetzt, dabei mit einer Hand das Gehäuse 3 der Handpumpe 1 gehalten und mit der anderen Hand der Handgriff 10 erfaßt (vgl. Fig. 1).To clean a blocked drain, the handset with its suction cup 2 is placed on the drain opening, holding the housing 3 of the hand pump 1 with one hand and gripping the handle 10 with the other hand (cf. FIG. 1).

Durch Auf- und Abbewegen der Kolbenstange 7 im Gehäuse 3 wird der Kolben 8 verschoben und dadurch entsteht in der Saugglocke 2 und in dem Gehäuse 3 ein Vakuum mit hoher Saugkraft, was zu einem sicheren Festsaugen der Saugglocke 2 um die Abflußöffnung herum und zu einem einwandfreien Heraussaugen der Verstopfungen führt.By moving the piston rod 7 up and down in the housing 3, the piston 8 is displaced and this creates a vacuum with high suction force in the suction cup 2 and in the housing 3, which results in the suction cup 2 being securely sucked around the drain opening and in a faultless manner Sucking out the blockages leads.

Bei der Arbeitsweise mit Vakuum (Saugen) liegt die Dichtungsscheibe 21 lose auf der Abstufung 5a auf, so daß sie sich in Flatterbewegung auf- und abbewegen kann und die Dichtungsscheibe 19 an der Einstellstange 18 ist durch Verschieben der Einstellstange 18 nach unten hin im Abstand zur Kolben-Unterseite eingestellt, wie in Fig. 2 und 5 dargestellt, so daß sich diese Dichtungsscheibe 19 ebenfalls in Flatterbewegungen auf- und abbewegen kann. Die obere Dichtungsscheibe 17 führt ebenfalls Flatterbewegungen durch, jedoch nur beim Verschieben nach unten, da dann die Luft im Gehäuse 3 und der Saugglocke 2 durch die Durchbrüche 12 im Kolben 8 nach oben strömt, während die Dichtungsscheibe 17 beim Verschieben des Kolbens 8 nach oben hin fest auf der Kolben-Oberseite aufliegt und die Durchbrüche 12 überdeckt, so daß dadurch im Gehäuse 3 und der Saugglocke 2 das Vakuum entsteht. Das Anlegen der Dichtungsscheibe 17 auf die Kolben-Oberseite erfolgt durch die oberhalb des Kolbens 8 im Gehäuse 3 befindliche Luft, die beim Hochziehen der Kolbenstange 7 auf die Dichtungsscheibe 17 einwirkt.When working with vacuum (suction), the sealing washer 21 lies loosely on the step 5a so that it can move up and down in a fluttering motion and the sealing washer 19 on the adjusting rod 18 is at a distance from one another by moving the adjusting rod 18 downward Piston underside set, as shown in Fig. 2 and 5, so that this sealing washer 19 can also move up and down in fluttering movements. The upper sealing disk 17 also performs fluttering movements, but only when moving downward, since then the air in the housing 3 and the suction bell 2 flows upward through the openings 12 in the piston 8, while the sealing disk 17 moves upward when the piston 8 is moved lies firmly on the top of the piston and covers the openings 12, so that the vacuum is created in the housing 3 and the suction bell 2. The sealing washer 17 is placed on the upper side of the piston by the air located above the piston 8 in the housing 3, which acts on the sealing washer 17 when the piston rod 7 is pulled up.

Durch das entstehende Vakuum, welches nach mehrmaligem Verschieben der Kolbenstange 7 seine volle Saugkraft hat, werden die Verstopfungen in der Saugglocke 2 und dem Gehäuse 3 nach oben hochgezogen und wenn der Kolben 8 seine oberste Stellung hat, können die Verstopfungen aus dem seitlichen Auslaufstutzen 14 abfließen.Due to the resulting vacuum, which has its full suction power after repeated displacement of the piston rod 7, the blockages in the suction cup 2 and the housing 3 are pulled upwards and when the piston 8 is in its uppermost position, the blockages can flow out of the lateral outlet connection 14 .

Soll das Handgerät mit Druckkraft arbeiten, dann wird die Einstellstange 18 nach oben verstellt, so daß die Dichtungsscheibe 19 dicht an der Kolben-Unterseite am Kolben 8 anliegt, wie in Fig. 4 dargestellt, und die Dichtungsscheibe 21 über das Zugglied 22 in die nach oben hochgeschwenkte Freigabestellung gemäß Fig. 3 gebracht, so daß der Durchfluß im Verbindungsstutzen 5 ständig freiliegt.If the handheld device is to work with compressive force, then the adjusting rod 18 is adjusted upward, so that the sealing washer 19 bears tightly against the piston underside on the piston 8, as shown in FIG. 4, and the sealing washer 21 via the tension member 22 into the 3, so that the flow in the connecting piece 5 is continuously exposed.

Beim Verschieben der Kolbenstange 7 nach unten hin sperrt die am Kolben 8 anliegende Dichtungsscheibe 19 die Durchbrüche 12 ab und es kann keine Luft nach oben durch den Kolben 8 hindurch, sondern die Luft wird durch den Kolben 8 nach unten gedrückt, dadurch komprimiert, und der Abfluß mit Druckkraft gereinigt, indem die Luft den Abfluß durchbläst.When the piston rod 7 is moved downward, the sealing disk 19 resting against the piston 8 closes off the openings 12 and no air can pass upward through the piston 8, but the air is pressed downward by the piston 8, thereby compressed, and the Drain cleaned with pressure by blowing the air through the drain.

Beim Reinigen von Toilettenabflüssen läßt sich die Saugglocke 2 umstülpen, so daß der Glockenmantel nach oben zeigt und dadurch sicher und abgedichtet in den Toilettenabflu einsetzbar ist.When cleaning toilet drains, the suction bell 2 can be turned inside out so that the bell jacket points upwards and can therefore be used safely and sealed in the toilet drain.

Mit 24 sind Puffer, wie Federn, Gummiringe od. dgl. bezeichnet, die um die Verbindungsbuchse 11 angeordnet sind und beim Verschieben der Kolbenstange 7 nach unten hin die Kolbenstangen-Endstellung gedämpft abbremsen.With 24 buffers, such as springs, rubber rings or the like. Are designated, which are arranged around the connecting bush 11 and brake the piston rod end position damped when moving the piston rod 7 down.

Es liegt im Rahmen der Erfindung, das Handgerät auch ohne die Dichtungen 19,21 und ohne Einstellstange 18 und Zugglied 22 mit Rast- oder Hebelverschlüssen 20,23 auszuführen - hierbei arbeitet dann das Handgerät immer mit Saugkraft und somit mit Vakuum.It is within the scope of the invention to design the hand-held device without the seals 19, 21 and without the adjusting rod 18 and tension member 22 with latching or lever locks 20, 23 - the hand-held device then always works with suction and thus with a vacuum.
