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.
Claims27
A vacuum cleaner having a plurality of operating modes and a plurality of distinct operating positions, comprising:
- (a) at least one motor and fan assembly for receiving a power supply signal and producing a suction airflow during use of the vacuum cleaner;
- at least one sensor adapted to sense a change in the operating mode based on a change in the operating position of said vacuum cleaner and generating a mode signal in response thereto;
- and
- (b) a controller responsive to said mode signal and adapted to vary said power supply signal.
A vacuum cleaner having a plurality of operating modes and a plurality of distinct operating positions, comprising:
- (i) suction means for receiving a power supply signal and producing a suction airflow during use of the vacuum cleaner;
- (ii) sensor means for sensing a change in the operating mode of said vacuum cleaner based on a change in the operating position of said vacuum cleaner and generating a mode signal, in response thereto;
- and
- (iii) processor means responsive to said mode signal and adapted to vary said power supply signal.
A vacuum cleaner having a plurality of operating modes, comprising:
- (i) at least one motor and fan assembly for receiving a power supply signal and producing a suction airflow during use of the vacuum cleaner, said vacuum cleaner having a plurality of distinct operating positions, each of said operating modes corresponding to one of said distinct positions;
- (ii) at least one switch for generating a mode signal corresponding to at least one of the operating modes;
- and
- (iii) a microprocessor responsive to said mode signal and adapted to vary said power supply signal.
