Abstract

A vacuum cleaner has a plurality of operating modes is provided.
The vacuum cleaner includes a power control system having at least one sensor for automatically sensing a change in the operating mode of the vacuum cleaner and for generating a mode signal. A
microprocessor responsive to the mode signal is adapted to vary the power supply signal being supplied to the vacuum cleaner motor and fan assembly.

Claims (19)

1. A vacuum cleaner reconfigurable between at least two positions, the vacuum cleaner comprising:
(a) suction means for receiving power and producing a suction airflow during use of the vacuum cleaner; and, (b) sensor means for sensing a change in the position of the vacuum cleaner and altering the power provided to the suction means in response thereto.
2. The vacuum cleaner as claimed in claim 1 wherein the sensor means includes a standby mode sensor for sensing a standby mode wherein a reduced power level is provided to the suction means in response thereto.
3. The vacuum cleaner as claimed in claims 1 or 2 wherein the sensor means further includes a high flow mode sensor for sensing a high flow mode wherein an increased power level is provided to the suction means in response thereto.
4. The vacuum cleaner as claimed in claims 1, 2 or 3 further comprising a rechargeable battery wherein the sensor means further includes a battery recharge mode sensor for sensing a battery recharge mode wherein a reduced power level is provided to the suction means in response thereto so that airflow is produced to cool the battery during recharge.
5. The vacuum cleaner as claimed in claims 1, 2 or 3 further comprising a rechargeable battery wherein the sensor means further includes a battery recharge mode sensor for sensing a battery recharge mode wherein a reduced power level is provided to the suction means in response thereto so that airflow is produced to cool the battery during recharge.
6. The vacuum cleaner as claimed in claims 1, 2, 4 or 5 wherein the sensor means includes a high flow mode sensor for sensing a high flow mode wherein an increased power level is provided to the suction means in response thereto.
7. The vacuum cleaner as claimed in claims 1, 2, 3 or 6 further comprising a rechargeable battery wherein the sensor means includes a battery sensor for sensing a battery recharge mode wherein a reduced power level is provided to the suction means in response thereto so that airflow is produced to cool the battery during recharge.
8. The vacuum cleaner as claimed in claim 1 wherein the vacuum cleaner is an upright vacuum cleaner having a cleaning head and an upper casing mounted thereon, the vacuum cleaner operating in a normal mode when the cleaning head is used to clean a surface, and the sensor means includes a high flow mode sensor for sensing a high flow mode when an auxiliary hose is in use and causing the suction means to produce an increased air flow through the vacuum cleaner.
9. The vacuum cleaner as claimed in any of claims 1 - 8 further comprising processor means responsive to a mode signal produced by the sensor means and adapted to vary a power supply signal provided to the suction means.
10. A vacuum cleaner reconfigurable between at least two positions, the vacuum cleaner comprising:
(a) at least one motor and fan assembly for receiving power and producing an airflow during use of the vacuum cleaner; and, (b) at least one sensor adapted to sense a change in the position of the vacuum cleaner and to alter the power provided to the at least one motor and fan assembly in response thereto.
11. The vacuum cleaner as claimed in claim 10 wherein the vacuum cleaner comprises a cleaning head and a main casing pivotally connected to the cleaning head, the at least one sensor being adapted to sense when the main casing is positioned generally vertically above the cleaning head.

13. The vacuum cleaner as claimed in claim 10 wherein the vacuum cleaner is an upright vacuum cleaner, the upright vacuum cleaner further includes an auxiliary hose connectable in airflow communication with the motor and fan member assembly, and a high flow mode sensor for sensing when the auxiliary hose is in use.
14. The vacuum cleaner as claimed in claim 13 further including a receptacle for releasably receiving the auxiliary cleaning hose, the high flow mode sensor being provided proximate the receptacle for sensing when the auxiliary cleaning hose is released from the receptacle.
15. The vacuum cleaner as claimed in claim 10 further comprising at least one power supply for generating the power.
16. The vacuum cleaner as claimed in claim 15 wherein the at least one power supply comprises a rechargeable battery.
17. The vacuum cleaner as claimed in claim 16 wherein the at least one sensor is adapted to sense when the vacuum cleaner is in battery recharge mode.
18. The vacuum cleaner as claimed in claim 16 further comprising an auxiliary motor and fan assembly, the auxiliary motor and fan assembly being located proximate to the battery and being connectable to a power source, the at least one sensor being adapted to sense when the vacuum cleaner is in battery recharge mode and being adapted to turn on the auxiliary motor and fan assembly so as to cool the battery during recharge.
19. The vacuum cleaner as claimed in claim 10 further comprising a controller responsive to a mode signal produced by the at least one sensor and adapted to vary a power supply signal delivered to the at least one motor and fan assembly.
