Description
Die
Erfindung betrifft ein Druckwasserreinigungsgerät, bestehend aus einer Pumpe
mit Saug- und Druckanschluss und einem elektrischen Antrieb. Ein
solches Druckwasserreinigungsgerät
ist beispielsweise bekannt aus der
Das dort beschriebene Druckwasserreinigungsgerät weist als Antrieb einen Schleifring-Motor, einen so genannten Universalmotor, auf. Dieser Motor weist zwar eine geringe Baugröße auf, arbeitet jedoch mit recht hohen Drehzahlen, so dass zum Antrieb einer Taumelscheibenpumpe ein Untersetzungsgetriebe erforderlich ist.The There described pressure water purifier has as drive a slip ring motor, a so-called universal motor, on. Although this engine has a low Frame size, However, it works with quite high speeds, allowing the drive a swash plate pump a reduction gear required is.
Der Antrieb von Kolbenpumpen erfordert im Allgemeinen ein relativ hohes Drehmoment bei geringerer Drehzahl, während Schleifringmotoren bei hoher Drehzahl ein geringeres Drehmoment aufbringen.Of the Actuation of piston pumps generally requires a relatively high Torque at lower speed, while slip ring motors at high speed to apply a lower torque.
Die Verwendung von schleifringlosen Motoren in Form von so genannten Asynchronmotoren mit außenliegendem Stator und innenliegendem Rotor haben zwar den Vorteil, dass bei hohem Drehmoment und geringerer Drehzahl ein Untersetzungsgetriebe nicht notwendig ist, solche Motoren sind jedoch meistens in schweren Ausführungen bekannt, bei leichteren Druckwasserreinigungsgeräten, insbesondere handgeführten Druckwasserreinigungsgeräten, kamen sie bisher jedoch nicht zum Einsatz.The Use of non-slip motors in the form of so-called Asynchronous motors with external Although the stator and internal rotor have the advantage that at high torque and lower speed, a reduction gear is not necessary, but such engines are mostly in heavy versions known, in lighter pressure water purification devices, especially hand-held pressurized water purification devices came they are not yet used.
Um die geforderten Drehmomente übertragen zu können, ist bei einem asynchronen Innenläufermotor ein relativ großer Durchmesser des Rotors erforderlich. Zusammen mit den außenliegenden Statorwicklungen wird die geforderte kompakte Baugröße nicht erreicht.Around transmit the required torques to be able to is in an asynchronous internal rotor motor a relatively large one Diameter of the rotor required. Together with the outer stator windings the required compact size is not achieved.
Das bei dem Universalmotor für den Antrieb von Pumpen zusätzlich erforderliche Getriebe soll durch die vorliegende Erfindung eingespart werden.The in the universal motor for the drive of pumps in addition required transmission is to be saved by the present invention become.
Erfindungsgemäß wird dazu
ein Druckwasserreinigungsgerät
mit den Merkmalen des Hauptanspruches verwendet. Es findet ein Aussenläufermotor
Anwendung. Der innenliegende Stator weist mindestens eine feste
Stromleiterwicklung auf, in welcher ein Magnetfeld induziert wird,
welches durch eine entsprechende Steuerelektronik gesteuert in Umfangsrichtung
im Stator umläuft.
Der Aussenläufer
ist ringförmig
ausgebildet und um den im Allgemeinen zylindrischen Statorkern im
Abstand (Luftspalt) drehbar angeordnet. Die mit ihrer Wirkfläche mit
abwechselnder Wirkungsrichtung nach innen angeordneten
Permanentmagnete
rufen eine Kraftwirkung hervor, welche den Aussenläufer in
Drehung versetzt.According to the invention, a pressurized water purification device with the features of the main claim is used. There is an external rotor motor application. The inner stator has at least one fixed conductor winding, in which a magnetic field is induced, which rotates controlled by a corresponding control electronics in the circumferential direction in the stator. The outer rotor is annular and rotatably disposed about the generally cylindrical stator core at a distance (air gap). The arranged with their active surface with alternating direction of action inwards
Permanent magnets cause a force effect, which sets the outer rotor in rotation.
Der an sich bekannte Motor hat den Vorteil, dass keine Schleifringe erforderlich sind und dass gerade bei kleinerer Bauweise der Läufer durch seinen gegenüber dem Stator größeren Durchmesser besonders zur Übertragung höherer Drehmomente geeignet ist.Of the known motor has the advantage that no slip rings are required and that just with a smaller design of the runner through his opposite the stator larger diameter especially for transfer higher Torques is suitable.
Eine besonders kompakte Bauweise ergibt sich, wenn als Pumpe eine Axialkolbenpumpe mit Taumelscheibe eingesetzt wird, wobei die Taumelscheibe an einer mit dem Aussenläufer verbundenen, rotationssymmetrisch zum Aussenläufer angeordneten Welle befestigt ist.A Particularly compact design results when as an axial piston pump pump is used with a swash plate, wherein the swash plate on a with the outer rotor connected, rotationally symmetrically mounted to the outer rotor shaft attached is.
Vorteilhaft ist es, wenn eine Axialkolbenpumpe mit Taumelscheibe verwendet wird, wobei die Taumelscheibe direkt am Aussenläufer des Elektromotors befestigt ist.Advantageous it is when a swash plate type axial piston pump is used wherein the swash plate is attached directly to the outer rotor of the electric motor is.
Ein besonders einfacher Aufbau ergibt sich, wenn als Pumpe eine Zahnradpumpe eingesetzt ist. Dabei ist es vorteilhaft, wenn eine Innenzahnradpumpe verwendet wird, wobei der Aussenläufer des Antriebsmotors an der pumpenabgewandten Seite mit Stegen oder einer Abdeckung versehen ist, an welcher eine Welle befestigt ist, die durch den Aussenläufer hindurch führt und an welcher drehfest das Innenzahnrad befestigt ist.One a particularly simple construction results when as a pump, a gear pump is used. It is advantageous if an internal gear pump is used, wherein the external rotor of the drive motor to the pump-facing side with webs or a cover provided is, to which a shaft is attached, passing through the outer rotor leads and at which rotatably the internal gear is fixed.
Bei einer besonderen Ausführungsform kann vorgesehen sein, dass an den Aussenläufer pumpenseitig über eine Abdeckscheibe oder Stege eine Welle angeformt ist, die das Innenzahnrad der Innenzahnradpumpe antreibt.at a particular embodiment can be provided that on the outer rotor pump side via a Cover plate or webs a shaft is formed, which forms the internal gear the internal gear pump drives.
Um ein Verkanten der Zahnräder der Innenzahnradpumpe zu verhindern, kann bei einer vorteilhaften Ausführung vorgesehen sein, dass zwischen der Welle des Aussenläufermotors und dem Innenzahnrad mindestens eine Kupplung vorgesehen ist. Dabei kann es sich beispielsweise um eine Klauenkupplung, Magnetkupplung oder ähnliches handeln.Around a tilting of the gears To prevent the internal gear pump can, in an advantageous execution be provided that between the shaft of the external rotor motor and the internal gear at least one clutch is provided. there it may, for example, a dog clutch, magnetic coupling or similar act.
Besonders vorteilhaft ist es, wenn das Druckreinigungsgerät mit einem Akkumulator versehen ist, der zur Speisung des Aussenläufermotors dient. Hier liegt ein besonderer Vorteil der Aussenläufermotoren begründet, denn die Aussenläufermotoren weisen einen gegenüber Schleifringmotoren um zirka 30% geringeren Energiebedarf bei gleicher abgegebener Leistung auf. Etwaige Leistungsverluste durch Getriebe entfallen.Especially It is advantageous if the pressure cleaning device provided with an accumulator is, which serves to feed the external rotor motor. Here is a particular advantage of the external rotor motors justified because the external rotor motors have one opposite Slip ring motors reduce energy consumption by about 30% for the same delivered power. Any power losses due to gearboxes omitted.
Die folgenden Ausführungsbeispiele dienen einer bevorzugten Ausführung der Erfindung.The following embodiments serve a preferred embodiment of the invention.
