Abstract

The washing machine with a series motor, has a brush arrangement in which the brushes (2) are held against the collector (1) of the motor during the spin drying cycle, and released during the washing cycle. For spin drying, an electromagnet (6) lifts a leaf spring (7) so that two arms (26, 26') are rotated about their spindles (27), and so as to rotate a roller (26") each side of the motor, and so that a bent arm (12) each side is forced against each brush (2), pushing it inwards against the motor collector (1). For the washing cycle, the electromagnet lowers the leaf spring, and pressure on the brushes (2) is removed.

Description

Bürstonandruckvorrichtung Die Erfindung betrifft eine Vorrichtung zum Andrücken der Bürsten des Reihenschlußmotorenteils eines Doppelmotors für den Antrieb einer Waschmaschine, wobei nur im Schleudergang die Bürsten auf den Kollektor des Reihenschlußmotors gedrückt werden, während bei Waschbetrieb ledglich die Andruckkraft auf die Bürsten aufgehoben wird, nach Patent ... (Patentanmeldung P 24 60 876.2). Brush Pressing Device The invention relates to a device for pressing the brushes of the series motor part of a double motor for the Drive of a washing machine, whereby the brushes on the collector only in the spin cycle of the series motor are pressed, while in washing mode only the pressure force on the brushes, according to patent ... (patent application P 24 60 876.2).

Bei Waschmaschinen mit einem Doppeimotorenantrieb ist es bekannt, daß bei Waschbetrieb das stromlose Mitlaufen des Reihenschlußmotors erhebliche Bürstengeräusche mit sich bringen kann.In washing machines with a double motor drive, it is known that during washing operation the currentless running of the series motor makes considerable brush noises can bring with it.

In der Patentanmeldung P 24 60 876.2 ist bereits eine Lösung vorgeschlagen, welche den vorerwähnten Nachteil vermeidet.In the patent application P 24 60 876.2 a solution is already proposed, which avoids the aforementioned disadvantage.

Die Aufgabe der Erfindung ist es nun, die in der Hauptanmeldung beschriebene Bürstenandruckvorrichtung zu verbessern und zu vereinfachen.The object of the invention is now that described in the main application Brush pressure device to improve and simplify.

Zu diesem Zweck ist die Erfindung dadurch gekennzeichnet, daß der Elektromagnet über Freilaufelemente mit den Kohlebürsten des Reihenschlußmotors in Wirkverbindung steht.To this end, the invention is characterized in that the Electromagnet via freewheeling elements with the carbon brushes of the series motor is in operative connection.

In einer bevorzugten Ausführung sind die Freilaufelemente als Klemmrollenfreiläufe mit Druckfedern ausgebildet.In a preferred embodiment, the freewheel elements are as clamping roller freewheels formed with compression springs.

Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung schematisch dargestellt.An embodiment of the invention is shown schematically in the drawing shown.

Die Zeichnung zeigt in vereinfachter Form die Bürstenandruck vorrichtung mit ihren funtionswesentlichen Teilen in Richtung auf den Kollektor 1 des Reihenschlußmotors gesehen.The drawing shows the brush pressure device in a simplified form with their essential parts in the direction of the collector 1 of the series motor seen.

Auf einer Trageplatte 25 sind die Freilaufelemente 26 angeordnet. Diese Feeilaufelemente 26 sind vorzugsweise allgemein bekannte Klemmrollenfreiläufe mit Druckfedern, welche eine KraftübertraguI1g nur in einer Richtung zulassen.The freewheel elements 26 are arranged on a support plate 25. These friction elements 26 are preferably well-known pinch roller freewheels with compression springs, which only allow force to be transmitted in one direction.

Die Freilaufelemente 26 bestehen im wesentlichen aus den Teilen 26' u. 26", Diese sind mittels Drehachse 27 drehbeweglich auf der Tragerplate 25 gelagert und werden von den Haltebügeln 28 gehalten. Die kraftübertragende Richtung ist durch die Pfeilmarkierung gekennzeichnet. Bei entgegengesetzter Bewegung kann sich das Teil 26' des Freilaufelementes 26 im Freilauf in die Ausgangslage zurückdrehen.The freewheel elements 26 essentially consist of the parts 26 ' u. 26 ″, these are rotatably mounted on the carrier plate 25 by means of the axis of rotation 27 and are held by the retaining brackets 28. The power transmitting direction is through marked by the arrow mark. With the opposite movement, this can happen Turn part 26 'of the freewheel element 26 back into the starting position while freewheeling.

Die Teile 26' der Freilaufelemente 26 sind miteinander über ein Angriffsteil 7 verbunden, während die Teile 26 " mit den Andruckgliedern 12 der Kohlebürsten 2 in Verbindung stehen.The parts 26 'of the freewheeling elements 26 are connected to one another via an engagement part 7 connected, while the parts 26 ″ with the pressure members 12 of the carbon brushes 2 related.

Das Angriffsteil 7 ist vorzugsweise als Blattfederelement ausgebildet.The attack part 7 is preferably designed as a leaf spring element.

Die Kohlebürsten 2 sind in bekannter Form federnd im Bürstenhalter 5 gehalten.The carbon brushes 2 are resilient in the brush holder in a known form 5 held.

Das Angriffsteil 7 ist mit dem Stößel 6' des Elektromagneten 6 verbunden.The engagement part 7 is connected to the plunger 6 ′ of the electromagnet 6.

Die Zeichnung zeigt die Position der Bürstenandruckvorrichtung beim strornlosen Mitlaufen des Reihenschlußmotors, also bei WaschbetriebO Soll die Waschmaschine den Schleudergang durchführen, wird der Elektromagnet 6 erregt uncl /ieht den Stößel 6' in den Spulenkörper hinein.The drawing shows the position of the brush pressure device at The in-line motor runs without a current, i.e. when the washing machine is in operation carry out the spin cycle, the electromagnet 6 is excited and the plunger 6 'into the bobbin.

Üher das Angriffsteil 7 werden die Fre; laufelemcnte 26 in der kraftübertragenden Richtung (Pfeilrichtung) bewegt, so daß die Andruckglieder 12 die Kohlebürsten 2 auf den Kollektor 1 des Motors drücken.Over the attack part 7 are the Fre; Laufelemcnte 26 in the power-transmitting Direction (arrow direction) moved so that the pressure members 12, the carbon brushes 2 Press on collector 1 of the motor.

Es findet also eine direkte Kraftübertragung vom Elektromag neten 6 auf die Kohlebürsten 2 statt.So there is a direct power transmission from the electromagnet 6 on the carbon brushes 2 instead.

Wenn der Elektromagnet 6 entregt wird, werden aucli die Kohlebürsten 2 entlastet, d.h. die Andruckkraft auf die Kohlebürsten 2 in Richtung auf den Kollektor 1 des Motors ist aufgehoben.When the electromagnet 6 is de-energized, the carbon brushes are also activated 2 relieved, i.e. the pressure on the carbon brushes 2 in the direction of the collector 1 of the motor is canceled.

Somit unterbleiben dann die störenden Geräusche bei Waschbetrieb, wenn der Reihenschlußmotor stromlos mitläuft.This means that there are no annoying noises when the washing machine is in operation, when the series motor is running without current.
