Abstract

The fan arrangement includes a fan motor whose speed can be controlled. A circuit board (13), which carries components of a speed control circuit, is contacted by the ends of the stator winding (9) of the fan motor.The ends of the stator winding are guided in connector sleeves (11) arranged on the stator plate packet (12). The circuit board has hooked connector contacts (14) on its rear side which hang in the connector sleeves on the stator plate packet.

Description

Die Erfindung betrifft einen Staubsauger mit einem Gebläseaggregat mit einem drehzahlsteuerbaren Gebläsemotor und mit einer Leiterkarte zur Aufnahme von Bauelementen einer Drehzahlsteuerung, welche mit den Leitungsenden der Sta­ torwicklung des Gebläsemotors kontaktiert ist.The invention relates to a vacuum cleaner with a blower unit with a speed controllable blower motor and with a circuit board for the admission of Components of a speed control, which with the line ends of the Sta Fan winding of the fan motor is contacted.

Es ist bekannt, bei Staubsaugern der vorgenannten Art die Leiterkarte zur Auf­ nahme der Bauelemente der Drehzahlsteuerung am Gebläsemotor oder in der Nähe desselben anzuordnen. Dabei erfolgt die Kontaktierung zwischen Statorwicklung und Leiterkarte über Litzen, welche mit der Statorwicklung verbunden werden und Steckkontakte zur Verbindung mit der Leiterkarte besitzen. Der Nachteil einer sol­ chen Verbindung besteht darin, daß wegen der ungeordneten Lage der Anschluß­ drähte alle Schritte, die zur Verbindung der Leiterkarte und der Statorwicklung er­ forderlich sind, von Hand ausgeführt werden müssen. Dies führt zu einer arbeitsintensiven und teuren Fertigung.It is known that the circuit board for vacuum cleaners of the aforementioned type Take the components of the speed control on the blower motor or nearby to arrange it. The contact is made between the stator winding and printed circuit board over strands, which are connected to the stator winding and Have plug contacts for connection to the circuit board. The disadvantage of a sol Chen connection is that because of the disordered location of the connection wires all the steps involved in connecting the circuit board and the stator winding are required to be done by hand. This leads to a labor-intensive and expensive manufacturing.

Der Erfindung stellt sich somit das Problem, einen Staubsauger mit einem Gebläseaggregat der vorgenannten Art zu schaffen, welcher durch eine Automatisierung der Kontaktierung von Leiterkarte und Statorwicklungen preiswert gefertigt werden kann.The invention thus turns this Problem to a vacuum cleaner with a blower unit of the type mentioned create which by automating the contacting of printed circuit boards and stator windings can be manufactured inexpensively.

Erfindungsgemäß wird dieses Problem mit den im Patentanspruch 1 angegebenen Merkmalen gelöst. Zweckmäßige Weiterbildungen und Ausgestaltungen ergeben sich aus den nachfolgenden Unteransprüchen.According to the invention, this problem is solved with those specified in claim 1 Features resolved. Appropriate further developments and refinements result arising from the following subclaims.

Die mit der erfindungsgemäßen Ausbildung erreichbaren Vorteile bestehen darin, daß die Enden der Statorwicklung ohne Litzen direkt manuell oder automatisch an die ortsfesten Kontakte der Steckhülsen am Statorblechpaket herangeführt und kontaktiert werden. Die weitere Kontaktierung zwischen Leiterkarte und Steckhülsen erfolgt durch eine Steckverbindung. Die vorgenannten Arbeitsschritte sind automatisierbar.The advantages achievable with the training according to the invention are that the ends of the stator winding directly or manually without strands the fixed contacts of the receptacles on the stator laminated core and be contacted. The further contact between the printed circuit board and Plug sleeves are made by a plug connection. The above steps can be automated.

Ein weiterer Vorteil besteht darin, daß die Leiterkarte durch die erfindungsgemäße Ausbildung als vorprüfbares Bauteil gefertigt werden kann. Another advantage is that the circuit board by the invention Training as a testable component can be made.  

In einer vorteilhaften Ausgestaltung der Erfindung ist am Motorlagerschild des Gebläseaggregats eine Anschraubfläche mit einer integrierten Positionierhilfe angeordnet, welche mit der Anschraubfläche eine schlitzartige Aufnahme für die Leiterkarte bildet. Hierdurch erfolgt eine Führung der Leiterkarte beim Einbau. Daneben kann in einer weiteren vorteilhaften Ausgestaltung der Erfindung die Masseverbindung durch eine rückseitige Beschichtung der Leiterkarte erfolgen. Eine vollautomatische Roboterfertigung ist somit in allen Bereichen möglich.In an advantageous embodiment of the invention, the Blower unit a screw-on surface with an integrated positioning aid arranged, which with the screw surface a slot-like receptacle for the PCB forms. As a result, the circuit board is guided during installation. In addition, in a further advantageous embodiment of the invention Ground connection is made by coating the circuit board on the back. Fully automated robot production is therefore possible in all areas.
