Definitions

  • the invention also relates to a suction tube for use with such a vacuum cleaner.
  • Such a vacuum cleaner is disclosed in document EP-A-0 136 357 and is also commercially available from Philips Electronics N.V. under the type number HR 6780.
  • the relevant commercially available vacuum cleaner comprises a suction tube with a remote control circuit adapted to switch on/off the electric motor of the vacuum cleaner and an electric motor of a brush, which brush can be fitted onto a suction nozzle forming part of the suction tube.
  • a vacuum cleaner is obtained which has several advantages in comparison with the above-mentioned commercially available vacuum cleaner.
  • a first advantage of the circuit constructed in accordance with the invention is that a clogged suction tube can be coupled to the vacuum-cleaner housing in a reverse manner. In this way the suction tube can be unclogged.
  • a second advantage of the circuit constructed in accordance with the invention is that a defect of the remote control circuit of the suction tube does not render the vacuum cleaner unserviceable.
  • a third advantage of the circuit constructed in accordance with the invention is that the vacuum cleaner can be provided with a connection to which the suction tube can be coupled to provide a blower function.
  • Figure 1B shows an electronic circuit arrangement of a prior-art vacuum cleaner, for example the vacuum cleaner which is commercially available from Philips Electronics N.V. under the type number HR 6780.
  • the electronic circuit arrangement comprises a part accommodated in the housing 100 and comprising the electric motor 110 and the electronic circuit 120, and a part accommodated in the suction tube 200 and comprising the remote control circuit 210.
  • the remote control circuit 210 accommodated in the suction tube 200 and the control circuit 121 are serially coupled between the supply voltage terminals 131 and 132 and the electric motor 110 and the triac 122 are also serially coupled between these terminals, the control circuit 121 being switched on/off by the remote control circuit 210 when the suction tube 200 is present.
  • the remote control circuit comprises a switch 211 coupled between two connectors 221 and 222. Since the control circuit 121 is powered via the remote control circuit 210 the electric motor 110 cannot be switched on when the suction tube 200 with the remote control circuit 210 is not coupled to the housing 100.
  • Fig. 3 shows a modification of the electronic circuit arrangement for a vacuum cleaner in accordance with the invention.
  • the modification has the advantage that the electronic circuit detects whether the suction tube is present.
  • the switch 211 of the remote control circuit 210 has a first position, in which a first conduction path between the supply voltage terminal 131 and the control circuit 121 is established, and a second position, in which a second conduction path between the supply voltage terminal 131 and the control circuit 121 is established, and the remote control circuit has a first resistor 212 included in the first conduction path and a second resistor 213 included in the second conduction path.
  • the remote control circuit 210 comprises a connector 223, which forms part of the coupling and which cooperates with a connector 143 included in the electronic circuit, a switch 214, and two connectors 213 and 232. If the switch 211 is in the first position the electric motor of the brush belonging to the suction tube 200 can be switched on/off by means of the switch 214, the electric motor being connected between the two connectors 213 and 232.
  • the use of the brush is known from the vacuum cleaner which is commercially available from Philips Electronics N.V. under the type number HR 6780.

Claims (7)

  1. Staubsauger mit einem mit einem Elektromotor (110) versehenen Gehäuse (100) und mit einer elektronischen Schaltung (120) zur Steuerung des Elektromotors (110), welches Gehäuse (100) zum Anschließen eines Schlauches (200) konstruiert ist, der mit einer Fernbedienungsschaltung (210) zur Steuerung der elektronischen Schaltung (120) versehen ist, dadurch gekennzeichnet daß die elektronische Schaltung (120) des Staubsaugers zur Steuerung des Elektromotors (110) sowohl bei mit dem Gehäuse (100) verbundenem als auch bei vom Gehäuse (100) gelöstem Schlauch (200) eingerichtet ist.
  2. Staubsauger nach Anspruch 1, dadurch gekennzeichnet, daß das Gehäuse (100) eine erste und eine zweite Speisespannungsklemme (131, 132) hat, daß bei vorhandenem Schlauch (200) über den Schlauch (200) ein Leitungspfad zwischen der elektronischen Schaltung (120) und der ersten Speisespannungsklemme (131) aufgebaut wird und bei nicht vorhandenem Schlauch (200) über das Gehäuse (100) ein Leitungspfad zwischen der elektronischen Schaltung (120) und der ersten Speisespannungsklemme (131) aufgebaut wird.
  3. Staubsauger nach Anspruch 2, dadurch gekennzeichnet, daß bei vorhandenem Schlauch (200) über das Gehäuse (100) ein Leitungspfad zwischen der elektronischen Schaltung (120) und der ersten Speisespannungsklemme (131) aufgebaut wird.
  4. Staubsauger nach Anspruch 3, dadurch gekennzeichnet daß die elektronische Schaltung (120) eine Teilschaltung (124) zum Detektieren des Vorhandenseins des Schlauches (200) am Gehäuse (100) umfaßt.
  5. Staubsauger nach Anspruch 4, dadurch gekennzeichnet, daß das Gehäuse (100) ein Display (150) umfaßt, welches Display (150) mit der elektronischen Schaltung (120) gekoppelt ist, um das Vorhandensein und Nicht-Vorhandensein des Schlauches (200) am Gehäuse anzuzeigen.
  6. Schlauch zur Verwendung mit einem Staubsauger nach Anspruch 4 oder 5, dadurch gekennzeichnet daß der Schlauch (200) eine Fernbedienungsschaltung (210) mit einem ersten und einem zweiten Widerstand (212, 213) umfaßt, wobei die Detektion des Vorhandenseins oder Nicht-Vorhandenseins des Schlauches (200) am Gehäuse (100) durch die elektronische Schaltung (120) des Staubsaugers auf einem Unterschied im Widerstandswert beruht.
  7. Schlauch nach Anspruch 6, dadurch gekennzeichnet, daß die Fernbedienungsschaltung (210) einen Schalter (211) umfaßt, der in einer ersten Stellung die erste Speisespannungsklemme (131) und die elektronische Schaltung (120) über den ersten Widerstand (212) koppeln kann und in einer zweiten Stellung die erste Speisespannungsklemme (131) und die elektronische Schaltung (120) über den zweiten Widerstand (213) koppeln kann.
