Abstract

The synchronised pump assembly, especially for pumping the washing fluid at a clothes of dishes washing machine, has a bayonet connection between the rotor housing and the pump housing. The seal (13) gives a material bond between the rotor and pump housings, using an injected thermoplastic elastomer such as "Santoprene" (RTM).

Description

Die Erfindung betrifft eine Synchronpumpe, insbesondere eine Laugenpumpe für Waschma­ schinen oder Geschirrspülmaschinen mit einem Rotorgehäuse, in dem ein mit einem Laufrad verbundener Rotor drehbar gelagert ist und mit einem Pumpengehäuse mit Zu- und Ablauf­ stutzen, welches lösbar mit dem Rotorgehäuse unter Zwischenlage einer Dichtung verbunden ist.The invention relates to a synchronous pump, in particular a drain pump for washing machines machines or dishwashers with a rotor housing in which one with an impeller connected rotor is rotatably mounted and with a pump housing with inlet and outlet clip, which is detachably connected to the rotor housing with the interposition of a seal is.

Solche Synchronpumpen werden beispielsweise als Aquarienpumpen eingesetzt. Die Verbin­ dung von Pumpengehäuse und Rotorgehäuse erfolgt durch an die Gehäuse angeformte Flanschplatten mittels einer Schraubverbindung. Als Dichtung wird dabei ein O-Ring in eine Vertiefung am Pumpengehäuseflansch eingelegt.Such synchronous pumps are used for example as aquarium pumps. The verb Pump housing and rotor housing are formed by integrally molded onto the housing Flange plates using a screw connection. An O-ring is used as a seal Recess placed on the pump housing flange.

Bei Waschmaschinen oder Geschirrspülmaschinen wird die Synchronpumpe als Laugenpumpe verwendet und ist aus diesem Grund an einem tiefen Punkt unter dem Laugen- oder Spülbehälter angeordnet. Sie muß deshalb mit einem Verbindungssystem ausgestattet sein, daß eine einfache Montage des Pumpengehäuses am Rotorgehäuse ermöglicht und zudem eine sichere Dichtwirkung gewährleistet. Aus der DE-OS 19 59 087 ist eine Bajonettverbindung zwischen dem Rotorgehäuse und dem Pumpengehäuse einer Pumpe bekannt. Als Dichtung fungiert dort ebenfalls ein separat einzulegender O-Ring. Eine solche Dichtung besitzt den Nachteil, daß sie beim Montieren oftmals nicht die exakte Position beibehält bzw. vollständig verloren gehen kann. Außerdem kommt es bei der Herstellung des Bajonettverschlusses durch das Drehen der beiden Gehäuseteile zueinander und die dadurch auftretende Reibung an der Dichtung zu undefinierten Verformungen, welche die Dichtwirkung beeinträchtigen. Diese Erscheinungen treten insbesondere dann auf, wenn die Pumpe bei einem möglichen Reparaturfall demontiert und unter ungünstigen Platzverhältnissen am Aufstellungsort der Waschmaschine oder Geschirrspülmaschine wieder zusammengesetzt wird.In washing machines or dishwashers, the synchronous pump is used as a drain pump used and for this reason is at a deep point under the lye or Rinsing container arranged. It must therefore be equipped with a connection system that allows easy assembly of the pump housing on the rotor housing and also ensures a secure sealing effect. From DE-OS 19 59 087 is a bayonet connection known between the rotor housing and the pump housing of a pump. As a seal there is also a separate O-ring. Such a seal has the Disadvantage that it often does not maintain the exact position or completely during assembly can get lost. It also comes through in the manufacture of the bayonet catch the rotation of the two housing parts to each other and the resulting friction on the Seal to undefined deformations that affect the sealing effect. This Symptoms occur particularly when the pump is at a possible Disassembly case dismantled and under unfavorable space conditions at the installation site of the Washing machine or dishwasher is put back together.

Der Erfindung stellt sich somit das Problem, eine Synchronpumpe der eingangs beschriebenen Art zu offenbaren, bei der eine einfache und dennoch sichere Verbindung zwischen Rotorge­ häuse und Pumpengehäuse möglich ist.The invention thus poses the problem of a synchronous pump of the type described in the introduction Kind of disclose where a simple yet secure connection between rotorge housing and pump housing is possible.

Erfindungsgemäß wird dieses Problem durch eine Synchronpumpe mit den im Patentan­ spruch 1 angegebenen Merkmalen gelöst. Vorteilhafte Ausgestaltungen und Weiterbildungen der Erfindung ergeben sich aus den nachfolgenden Unteransprüchen. According to the invention, this problem is solved by a synchronous pump with the in the patent solved claim 1 specified features. Advantageous refinements and developments the invention result from the following subclaims.  

Der mit der Erfindung erreichbare Vorteil ergibt sich dadurch, daß eine exakte, unveränderbare Position der Dichtung grundsätzlich sichergestellt ist, so daß die Fehlerrate, die sich beim Mon­ tieren einer separaten Dichtung ergeben kann, erheblich vermindert wird.The advantage achievable with the invention results from the fact that an exact, unchangeable Position of the seal is fundamentally ensured, so that the error rate, which is the Mon animals can result in a separate seal is significantly reduced.

Als besonders vorteilhaft hat es sich erwiesen, die Dichtung aus einem thermoplastischen Elastomer (Santoprene) auszubilden und am Rotor- oder Pumpengehäuse anzuspritzen. Im Innenraum des Rotorgehäuses ist bekanntlich der mit Lauge umspülte Rotor gelagert, wodurch zwangsläufig ein laugenbeständiger Werkstoff (Polypropylen) eingesetzt werden muß. Santo­ prene besitzt die Eigenschaft, mit Polypropylen eine stoffschlüssige Bindung einzugehen, so daß die Dichtung angespritzt werden kann.It has proven to be particularly advantageous to use a thermoplastic seal Form elastomer (Santoprene) and spray on the rotor or pump housing. in the As is known, the interior of the rotor housing supports the rotor, which is washed with alkali, thereby an alkali-resistant material (polypropylene) must be used. Santo prene has the property of forming a material bond with polypropylene, so that the seal can be molded.
