Abstract

The invention relates to a vacuum cleaner with a built-in cable drum in the housing. The output contacts on the end of the cable are configured as contact plugs (9) and are connected to matching contacts (15) provided on a printed board (13) that is mounted next to the cable drum (6) on the vacuum cleaner housing. The contact plugs (9) of the cable drum (6) are aligned parallel to each other and stand out axially in relation to the outer contour of the cable drum (6). The matching contact plugs are shaped as slotted contacts (15) which are connected to each other by conducting a relative movement in relation to each other and parallel to the plane of the corresponding cable drum side. The cable drum and the printed board can thus be rationally integrated in the vacuum cleaner housing.

Description

Staubsaugervacuum cleaner

Die Erfindung betrifft einen Staubsauger, mit einer in dessen Gehäuse eingebauten Kabeltrommel, deren kabelendseitigen Ausgangskontakte als Steckkontakte ausgebildet und mit an einer im Staubsaugergehäuse neben der Kabeltrommel angeordneten Leiterplatte vorgesehenen Gegensteckkontakten verbunden sind.The invention relates to a vacuum cleaner, with a cable drum installed in its housing, the cable end-side output contacts of which are designed as plug contacts and are connected to mating plug contacts provided on a circuit board arranged in the vacuum cleaner housing next to the cable drum.

ein solcher Staubsauger ist durch die EP-A-0 365 797 bekannt. Bei diesem bekannten Staubsauger ist ein aus Kunststoff bestehendes Tragteil vorgesehen, an dem ein axial vorstehender Ansatz angeformt ist, in dessen Innenraum Gegensteckkontakte angeordnet sind, die mit in einer Nabenvertiefung des feststehenden Gehäuseteiles einer Kabeltrommel vorgesehenen Steckkontakten zusammen passen. Der Ansatz ist von seinen Abmessungen her so ausgeführt, daß er in die Nabenvertiefung paßt und in dieser gehalten wird. Auf diese Weise wird das Tragteil an der Kabeltrommel gehalten. Auf der der Kabeltrommel abgewandten Seite des Tragteiles ist eine mit den elektrischen Steuerelementen für den Gebläsemotor bestückte Leiterplatte angebracht. Bevor die Kabeltrommel in das Staubsaugergehäuse eingesetzt wird, muß bereits die Tragplatte mit der an ihr befindlichen Leiterplatte an die Kabeltrommel angefügt werden. Desgleichen muß bei einem Störungsfall an der Leiterplatte oder der Kabeltrommel die komplette aus Kabeltrommel und Tragteil bestehende Einheit ausgebaut werden.such a vacuum cleaner is known from EP-A-0 365 797. In this known vacuum cleaner, a plastic support part is provided, on which an axially protruding projection is formed, in the interior of which mating plug contacts are arranged which fit together with plug contacts provided in a hub recess of the fixed housing part of a cable drum. The approach of its dimensions is carried out so that it fits into the hub recess and is held in this. In this way, the supporting part is held on the cable drum. A circuit board equipped with the electrical control elements for the blower motor is attached to the side of the support part facing away from the cable drum. Before the cable drum is inserted into the vacuum cleaner housing, the support plate with the circuit board located on it must already be attached to the cable drum. Likewise, in the event of a malfunction on the circuit board or the cable drum, the complete unit consisting of the cable drum and the supporting part must be removed.

Der Erfindung liegt die Aufgabe zugrunde, einen Staubsauger der eingangs beschriebenen Art so weiterzubilden, daß die Kabeltrommel und die Leiterplatte in rationeller Weise in das Staubsaugergehäuse ein- und ausgebaut werden können.The invention has for its object to develop a vacuum cleaner of the type described above so that the cable drum and the circuit board can be installed and removed in a rational manner in the vacuum cleaner housing.

Die Lösung der gestellten Aufgabe gelingt nach der Erfindung dadurch, daß die Steck- kontakte der Kabeltrommel parallel zueinander ausgerichtet sind und gegenüber der Außenkontur der Kabeltrommel axial vorstehen, daß ferner die Gegensteckkontakte als Schlitzkontakte ausgebildet sind, die durch eine relativ zueinander ausgeführte, parallel zur Ebene der betreffenden Kabeltrommelseite verlaufende Bewegung in Kontaktverbindung bringbar sind. Bei einer solchen Ausgestaltung eines Staubsaugers stimmt die Bewegungsrichtung für das Zusammenfügen der Steck- und Gegensteckkontakte mit der Montagerichtung der Kabeltrommel und der Leiterplatte überein, so daß beim Einsetzen dieser Teile in das Staubsaugergehäuse die Kontaktverbindung selbsttätig hergestellt wird. Desgleichen kann bei einem Störungsfall an einem dieser Teile das betreffende Teil aus dem Staubsaugergehäuse herausgezogen werden, wobei die Kontaktverbindung gelöst wird, ohne daß das andere Teil aus dem Staubsaugergehäuse herausgenommen werden muß.The object is achieved according to the invention in that the plug contacts of the cable drum are aligned parallel to one another and project axially relative to the outer contour of the cable drum, and in addition that the mating plug contacts are designed as slot contacts, which are embodied parallel to the plane by a relative design of the relevant cable drum side running movement can be brought into contact. With such a configuration of a vacuum cleaner agrees the direction of movement for joining the plug and mating contacts with the mounting direction of the cable drum and the circuit board, so that when these parts are inserted into the vacuum cleaner housing, the contact connection is established automatically. Likewise, in the event of a malfunction in one of these parts, the part in question can be pulled out of the vacuum cleaner housing, the contact connection being released without the other part having to be removed from the vacuum cleaner housing.

Besonders vorteilhaft ist es, daß im Staubsaugergehäuse jeweils eine Führung für die Kabeltrommel und die Leiterplatte vorgesehen ist, wobei die Führungen so ausgebildet und angeordnet sind, daß beim Einbau der Kabeltrommel und der Leiterplatte die Steck- und die Schlitzkontakte selbsttätig miteinander in Kontaktverbindung gelangen.It is particularly advantageous that a guide for the cable drum and the printed circuit board is provided in each case in the vacuum cleaner housing, the guides being designed and arranged such that the plug and slot contacts automatically come into contact with one another when the cable drum and the printed circuit board are installed.

Dadurch, daß die Schlitzkontakte an beiden Stirnseiten offen ausgebildet sind, muß keine bestimmte Einbaufolge für die Kabeltrommel und die Leiterplatte eingehalten werden. Es kann wahlweise zuerst die Leiterplatte oder die Kabeltrommel in das Staubsaugergehäuse eingebracht werden.Due to the fact that the slot contacts are open at both ends, no particular installation sequence for the cable drum and the printed circuit board has to be observed. The circuit board or the cable drum can either be inserted into the vacuum cleaner housing first.

Anhand eines in der Zeichnung dargestellten Ausführungsbeispieles wird die Erfindung nachfolgend noch näher erläutert.Based on an embodiment shown in the drawing, the invention is explained in more detail below.

Steckkontakte einer Kabeltrommel mit den an einer Leiterplatte vorgesehenen Schlitzkontakten.Plug contacts of a cable drum with the slot contacts provided on a printed circuit board.

Mit 1 ist der Gebläseraum eines Staubsaugers bezeichnet. Der Gebläseraum 1 ist durch eine Trennwand 2 in einen das Gebläseaggregat 3 des Staubsaugers aufnehmenden ersten Teilraum 4 und einen eine Kabeltrommel 6 aufnehmenden zweiten Teilraum 5 unterteilt. Auf der in dem zweiten Teilraum 5 eingesetzten Kabeltrommel 6 ist das Anschlußkabel 7 des Staubsaugers aufgewickelt. Die Kabeltrommel 6 ist drehbar an einem feststehenden Gehäuseteil 8 gelagert. Dieses Gehäuseteil 8 enthält ferner einen die Kabeltrommel 6 in Aufwickelrichtung antreibenden Federmotor. Außerdem ist in dem Gehäuseteil 8 auch noch eine Schleifringanordnung eingebaut, durch die eine elektrisch leitende Verbindung zwischen dem auf der Kabeltrommel 6 aufgewickelten Anschlußkabel 7 und axial aus dem Gehäuseteil 8 vorragenden Steckkontakten 9 hergestellt ist. Die beiden Steckkontakte 9 sind sowohl in axialer Richtung als auch in Richtung ihrer seitlichen Kontaktflächen 10 parallel verlaufend ausgebildet.With 1 the blower compartment of a vacuum cleaner is designated. The blower chamber 1 is divided by a partition 2 into a first sub-chamber 4 receiving the blower unit 3 of the vacuum cleaner and a second sub-chamber 5 receiving a cable drum 6. On the cable drum 6 used in the second compartment 5, the connecting cable 7 of the vacuum cleaner is wound up. The cable drum 6 is rotatably mounted on a fixed housing part 8. This housing part 8 contains also a spring motor driving the cable drum 6 in the winding direction. In addition, a slip ring arrangement is also built into the housing part 8, by means of which an electrically conductive connection is made between the connecting cable 7 wound on the cable drum 6 and plug contacts 9 projecting axially from the housing part 8. The two plug contacts 9 are designed to run parallel both in the axial direction and in the direction of their lateral contact surfaces 10.

In U-förmige, an Wandteilen 2 und 11 des zweiten Teilraumes 5 vorgesehene Füh- rungssschlitze 12 ist eine Leiterplatte 13 mit ihren Seitenkanten 14 eingesteckt. Desgleichen ist eine in der Zeichnung nicht sichtbare Führung für die Kabeltrommel 6 vorhanden. Durch diese Führung wird die Kabeltrommel 6 beim Einsetzen in den zweiten Teilraum 5 in ihrer Lage so festgelegt, daß ihre Steckkontakte 9 mit an der Leiterplatte 13 angeordneten Schlitzkontakten 15 in Kontaktverbindung gelangen.A circuit board 13 with its side edges 14 is inserted into U-shaped guide slots 12 provided on wall parts 2 and 11 of the second partial space 5. Likewise, a guide for the cable drum 6 is not shown in the drawing. With this guidance, the cable drum 6 is fixed in its position when it is inserted into the second subspace 5 such that its plug contacts 9 come into contact with slot contacts 15 arranged on the printed circuit board 13.

Die Schlitzkontakte 15 sind an ihren beiden Stirnseiten 16 offen ausgebildet. Damit kann der Einbau der Leiterplatte 13 und der Kabeltrommel 6 in das Staubsaugergehäuse in beliebiger Reihenfolge geschehen. Es kann beispielsweise zuerst die Leiterplatte 13 in die Führungsschlitze 12 eingesteckt und danach die Kabeltrommel 6 in das Staubsaugergehäuse eingesetzt werden. Desgleichen ist eine umgekehrte Montagefolge möglich. Auch bei einem Störfall kann sowohl die Leiterplatte 13 als auch die Kabeltrommel 6 jeweils für sich aus dem Staubsaugergehäuse herausgenommen werden. The slot contacts 15 are open at their two end faces 16. This allows the circuit board 13 and the cable drum 6 to be installed in the vacuum cleaner housing in any order. For example, the circuit board 13 can first be inserted into the guide slots 12 and then the cable drum 6 can be inserted into the vacuum cleaner housing. A reverse assembly sequence is also possible. Even in the event of a malfunction, both the printed circuit board 13 and the cable drum 6 can be removed individually from the vacuum cleaner housing.
