Description

Die Erfindung betrifft eine Abflußreinigungspistole gemäß Oberbegriff des Anspruchs 1.The invention relates to a drain cleaning gun according to the preamble of the claim 1.

Zur Reinigung von Abflußrohren können mit Druckluft betriebene Reinigungspistolen verwendet werden, die einen Pistolengriff und ein mittels eines Handhebels betätigbares Druckluftventil besitzen. Die Druckluft strömt aus einer Reinigungsdüse oder einem Reinigungsrohr aus, so daß Verstopfungen oder Rückstände mit der Druckluft gelöst werden können. Bei hartnäckigen Verstopfungen kann jedoch die Anwendung von Druckluft alleine oftmals nicht den gewünschten Reinigungseffekt erzielen.Cleaning guns operated with compressed air can be used to clean drain pipes be used, the one pistol grip and one by means of a hand lever have actuatable compressed air valve. The compressed air flows from a cleaning nozzle or a cleaning pipe, so that blockages or residues with the Compressed air can be released. With persistent constipation, however Using compressed air alone often does not have the desired cleaning effect achieve.

Der Erfindung liegt die Aufgabe zugrunde, eine Abflußreinigungspistole zu schaffen, mit der Abflüsse und insbesondere Abflußrohre von Verstopfungen und Innenverschmutzungen befreit werden können.The invention has for its object to provide a drain cleaning gun with the drains and in particular drain pipes from blockages and Internal dirt can be freed.

Die Lösung dieser Aufgabe erhält man durch die im Anspruch 1 angegebenen Merkmale. An der Abflußreinigungspistole zweigt vor einer Mischkammer ein Anschlußstück ab, über das Wasser oder eine andere Flüssigkeit von einer unter Druck stehenden Leitung zugeführt werden kann. Die Flüssigkeit wird in einer Mischkammer mit der Druckluft vermischt so daß ein hochwirksamer Reinigungsstrahl aus einem Luft-Flüssigkeitsgemisch an einer Auslaßdüse mit entsprechend hohem Druck ausströmen kann. The solution to this problem is obtained by the specified in claim 1 Characteristics. On the drain cleaning gun branches in front of a mixing chamber Connector, over the water or other liquid from one under pressure standing line can be supplied. The liquid is in a mixing chamber mixed with the compressed air so that a highly effective cleaning jet from one Air-liquid mixture at an outlet nozzle with a correspondingly high pressure can flow out.

Die bevorzugte Ausführung sieht vor, daß das Anschlußstück über einen Schlauch an das Wasserleitungsnetz angeschlossen ist. Dabei kann an dem Schlauch oder im Bereich des Anschlußstücks ein Rückschlagventil angeordnet sein, welches verhindert, daß das Wasser von der Druckluft zurückgedrückt wird. Außerdem kann ein entsprechendes Rückschlagventil auch in der Druckluftleitung angeordnet sein, damit kein Wasser in die Druckluftleitung strömen kann.The preferred embodiment provides that the connector on a hose the water supply network is connected. It can be on the hose or in A check valve can be arranged in the area of the connecting piece, which prevents that the water is pushed back by the compressed air. In addition, a Corresponding check valve can also be arranged in the compressed air line so that no water can flow into the compressed air line.

Besonders vorteilhaft ist es, wenn am Anschlußstück ein Flüssigkeitsventil angebracht ist, mit dem die einströmende Wassermenge dosierbar ist. Das Flüssigkeitsventil kann als regulierbarer und abstellbarer Kugelhahn ausgebildet sein.It is particularly advantageous if a liquid valve is attached to the connector with which the inflowing amount of water can be metered. The liquid valve can be designed as an adjustable and switchable ball valve.

Um eine optimale Vermischung zwischen Druckluft und der zugeführten Flüssigkeit zu erhalten, ist das Anschlußstück für die Flüssigkeit gegenüber der Auslaßöffnung des zur Mischkammer führenden Druckluftkanals zurückgesetzt angeordnet.To ensure optimal mixing between compressed air and the supplied liquid received, the connector for the liquid is opposite the outlet of the to the mixing chamber leading compressed air duct arranged reset.

Bei der bevorzugten Ausführungsform ist am vorderen Ende des Reinigungsschlauchs eine Auslaßdüse mit einer Kernbohrung und mit im spitzem Winkel dazu angeordneten Seitenkanälen angebracht. Die Seitenkanäle sind gegenüber der Austrittsöffnung der Auslaßdüse nach hinten gerichtet, so daß ein entsprechend nach hinten gerichteter Reinigungsstrahl aus diesen Seitenkanälen austreten kann. Dies bewirkt, daß die Auslaßdüse mit der dadurch entstehenden Rückstoßkraft in das zu reinigende Abflußrohr eindringt. Dadurch erhält man einen optimalen Vorschub für die Auslaßdüse und gelangt problemlos auch an tiefer gelegene Positionen in einem zu reinigenden Abflußrohr.In the preferred embodiment is at the front end of the cleaning hose an outlet nozzle with a core bore and arranged at an acute angle to it Side channels attached. The side channels are opposite the outlet of the Exhaust nozzle directed backwards, so that a correspondingly directed backwards Cleaning jet can escape from these side channels. This causes the Outlet nozzle with the resulting recoil force into the one to be cleaned Drain pipe penetrates. This gives you an optimal feed for the Outlet nozzle and easily reaches even lower positions in one cleaning drainpipe.

Die Auslaßdüse kann sich nach vorne verjüngen oder kann auch kugelförmig ausgebildet sein. Dabei ist es besonders vorteilhaft, wenn die Auslaßdüse um ihre in Verlängerung des Reinigungsschlauchs verlaufende Längsachse drehbar mit dem Reinigungsschlauch verbunden ist. Das durch die Auslaßdüse strömende Luft-Flüssigkeitsgemisch kann die Auslaßdüse in Rotation versetzen, so daß mittels Rippen oder anderen Erhebungen, die sich an der Mantelfläche der Auslaßdüse befinden, eine zusätzliche mechanische Reinigung der Rohrwandung eines Abflußrohres möglich ist.The outlet nozzle can taper towards the front or can also be spherical be trained. It is particularly advantageous if the outlet nozzle for their in Extension of the cleaning hose running longitudinal axis rotatable with the Cleaning hose is connected. The air-liquid mixture flowing through the outlet nozzle can rotate the outlet nozzle so that by means of ribs or other elevations, which are located on the outer surface of the outlet nozzle, a additional mechanical cleaning of the pipe wall of a drain pipe is possible.

Damit die Auslaßdüse in Rotation versetzt wird, kann die Kernbohrung ein entsprechendes Innenprofil haben oder es können die Seitenkanäle entsprechend ausgerichtet sein.So that the outlet nozzle is set in rotation, the core hole can have the corresponding inner profile or the side channels can be corresponding be aligned.

Damit beim Reinigungsvorgang keine Flüssigkeit aus dem Abflußrohr nach oben unkontrolliert herausgedrückt wird, kann am Reinigungsschlauch ein Abdichtstopfen längsverschiebbar angebracht sein. Mit dem Abdichtstopfen kann der Abfluß, beispielsweise im Bereich eines Spülbeckens, abgedichtet werden, ohne daß dadurch das Einführen des Reinigungsschlauchs behindert wird.So that no liquid from the drain pipe goes up during the cleaning process is pushed out in an uncontrolled manner, a sealing plug can be attached to the cleaning hose be attached longitudinally. With the sealing plug, the drain, for example in the area of a sink, can be sealed without this the insertion of the cleaning hose is hindered.

Die Erfindung wird nachfolgend anhand eines in der Zeichnung dargestellten Ausführungsbeispiels näher erläutert.The invention is illustrated below with the aid of one in the drawing Embodiment explained in more detail.

Die in Figur 1 dargestellte Abflußreinigungspistole besitzt einen Pistolengriff 1 mit einem Handhebel 2, über den die zugeführte Druckluft 3 dosierbar ist. Der Handhebel 2 wirkt auf ein hier nicht näher dargestelltes Dosierventil, an das ein zu einer Mischkammer 4 führender Druckluftkanal 5 angeschlossen ist. Der Druckluftkanal 5 ist von einem Ringspalt 6 umgeben, in dessen Bereich ein Anschlußstück 7 abzweigt. An das Anschlußstück 7 ist über eine flexible Leitung 8 eine Verbindung zum Wasserleitungsnetz hergestellt, so daß Wasser 9 mit Druck am Anschlußstück 7 anliegt.The drain cleaning gun shown in Figure 1 has a pistol grip 1 with a hand lever 2, via which the supplied compressed air 3 can be metered. The hand lever 2 acts on a metering valve, not shown here, to which one to one Mixing chamber 4 leading compressed air duct 5 is connected. The compressed air duct 5 is surrounded by an annular gap 6, in the area of which a connector 7 branches off. At the connector 7 is a connection to a flexible line 8 to Water supply network made so that water 9 with pressure at the connector 7th is present.

Um eine Dosierung des zugeführten Wassers 9 zu ermöglichen, besitzt das Anschlußstück 7 ein Flüssigkeitsventil 10, welches hier nur schematisch angedeutet ist. Das Flüssigkeitsventil 10 kann als Kugelhahn oder in anderer Weise als regulierbares und abstellbares Ventil ausgebildet sein.In order to enable metering of the water 9 supplied, this has Connector 7, a liquid valve 10, which is only indicated schematically here. The liquid valve 10 can be used as a ball valve or in some other way as an adjustable valve and shut-off valve be formed.

Die Mischkammer 4 der Abflußreinigungspistole geht in einen angeschlossenen Reinigungsschlauch 11 über, der mehrere Meter lang sein kann. Am vorderen Ende des Reinigungsschlauch 11 befindet sich eine konische Auslaßdüse 12, die eine Kernbohrung 13 und in spitzem Winkel verlaufende, nach hinten gerichtete Seitenkanäle 14, 15 hat. Der aus einem Flüssigkeits-Luftgemisch bestehende Reinigungsstrahl tritt somit nicht nur an der vorderen Austrittsöffnung 16 der Auslaßdüse 12 aus, sondern auch an den in der Mantelfläche der Auslaßdüse 12 befindlichen Austrittsöffnungen der Seitenkanäle 14, 15. Der Aus den Seitenkanälen 14, 15 austretende Reinigungsstrahl erzeugt eine Rückstoßkraft, mit der die Auslaßdüse 12 und damit der gesamte Reinigungsschlauch 11 selbsttätig in ein zu reinigendes Abflußrohr vordringt.The mixing chamber 4 of the drain cleaning gun goes into a connected one Cleaning hose 11, which can be several meters long. At the front of the Cleaning hose 11 is a conical outlet nozzle 12, the one Core bore 13 and at an acute angle, directed towards the rear Has side channels 14, 15. The one consisting of a liquid-air mixture Cleaning jet thus occurs not only at the front outlet opening 16 Exhaust nozzle 12, but also in the outer surface of the exhaust nozzle 12th located outlet openings of the side channels 14, 15. The out of the side channels 14, 15 emerging cleaning jet generates a recoil force with which the Outlet nozzle 12 and thus the entire cleaning hose 11 automatically into one cleaning drain pipe penetrates.

In Figur 2 ist die Auslaßdüse 12 von Figur 1 vergrößert dargestellt. Die in Figur 3 dargestellte Auslaßdüse 17 hat die Form einer Kugel und ist über ein Drehgelenk 18 mit dem Reinigungsschlauch 11 verbunden. Der Pfeil 19 deutet an, daß die Auslaßdüse 17 durch das hindurchströmende Flüssigkeits-Luftgemisch in Rotation versetzt wird. Die an der Mantelfläche 20 angebrachten Kerben oder Erhebungen 21 ermöglichen ein zusätzliches mechanisches Ausreiben der zu reinigenden Abflußrohre. In diesem Zusammenhang ist auch wichtig, daß die Seitenkanäle 14, 15 nicht nur einen selbsttätigen Vorschub für die Auslaßdüse 17 bzw. 12 erzeugen, sondern auch eine direkte Reinigung der Innenwand eines Abflußrohres ermöglichen.In Figure 2, the outlet nozzle 12 of Figure 1 is shown enlarged. The in Figure 3 The outlet nozzle 17 shown has the shape of a ball and is via a swivel joint 18th connected to the cleaning hose 11. The arrow 19 indicates that the outlet nozzle 17 is set in rotation by the flowing liquid-air mixture. The notches or elevations 21 made on the lateral surface 20 allow one additional mechanical rubbing of the drain pipes to be cleaned. In this Connection is also important that the side channels 14, 15 are not only one generate automatic feed for the outlet nozzle 17 or 12, but also a Allow direct cleaning of the inside wall of a drain pipe.
