Definitions
- the invention relates to a vacuum cleaner, with a certain condition in the Vacuum cleaner indicating device, in which by means of a between the Ambient pressure and the negative pressure prevailing in the dust chamber of the vacuum cleaner existing pressure difference actuatable electrical switching device electrical display element is switchable.
- Such a vacuum cleaner is known from DE-B-27 12 201.
- an electrical switching device is provided, in which one between the ambient pressure and the negative pressure prevailing in the dust room existing pressure difference exposed membrane is coupled with a switching pin. As a result of a movement of the membrane caused by the pressure difference the switching pin comes into contact with a mating contact and thereby closes the Circuit of an indicator light.
- this known vacuum cleaner is a separate one electrical connection of the switching device required.
- the switching device connected to the channel 9 by means of its connecting edge 15 14 contains a piston 21 in its housing capsule 20, which is supported by a spring 22 is held sealingly against an inlet opening 23 of the housing capsule 20.
- On the side opposite the inlet opening 23 is one of the connecting edge 15 Surrounded connection opening 24 is provided.
- At the bottom of the housing capsule 20 are further arranged electrical contact elements, between which by a on the piston 21 arranged switching bridge a conductive connection can be established.
- the contact elements are connected on the other hand with conductor tracks, through which in turn the contact connection for a display element.

Claims (4)
- Staubsauger, mit einer einen bestimmten Zustand im Staubsauger anzeigenden Vorrichtung, bei der mittels einer durch den zwischen dem Umgebungsdruck und dem im Staubraum (2) des Staubsaugers herrschenden Unterdruck bestehenden Druckunterschied betätigbaren elektrischen Schaltvorrichtung (14) ein elektrisches Anzeigeelement schaltbar ist, dadurch gekennzeichnet, daß die Schaltvorrichtung (14) direkt auf einer im Staubsaugergehäuse (1) eingebauten Leiterplatte (13) angeordnet ist und die elektrische Verbindung zwischen der Schaltvorrichtung (14) und dem Anzeigeelement über die Leiterbahnen der Leiterplatte (13) erfolgt.
- Staubsauger nach Anspruch 1, dadurch gekennzeichnet, daß die Schaltvorrichtung (14) mit ihrer Unterdruckseite an einen im Staubsaugergehäuse (1) ausgebildeten, durch den im Staubraum (2) des Staubsaugers herrschenden Unterdruck beaufschlagten, röhrenförmigen Kanal (9) abgedichtet angeschlossen ist.
- Staubsauger nach Anspruch 2, dadurch gekennzeichnet, daß fluchtend zu der an den Kanal (9) anschließbaren Unterdruckseite der Schaltvorrichtung (14) an der Leiterplatte (13) ein der Drehzahlsteuerung des Gebläsemotors des Staubsaugers dienendes Halbleiterschaltelement (25) in den Kanal (9) ragend angeordnet ist
- Staubsauger nach Anspruch 3, dadurch gekennzeichnet, daß an unterschiedlichen Umfangsstellen der Kanalwand mindestens zwei hinsichtlich ihres Höhenniveaus gegeneinander versetzten Durchbrechungen (16 und 19) derart angeordnet sind, daß diese auf ihrer dem Staubraum (2) benachbarten Seite im Bereich unterschiedlicher Strömungsgeschwindigkeiten des Saugluftstromes liegen.
