Abstract (en)

[origin: US2007061997A1] In an electric vacuum cleaner including a communicating tube forming an air trunk which communicates to a suction opening which suctions dust and a vacuum cleaner main body having a communicating tube attachment member attaching the communicating tube, a strain gauge is attached to a floor surface side of the communicating tube attachment member. This strain gauge is connected to one side of a resistor bridge circuit. Tension acts on the strain gauge due to an operation of the communicating tube during the cleaning so that an output is generated at the resistor bridge circuit. After being amplified, this output is differentiated in a condenser. This differentiated voltage signal is compared to a threshold level voltage in a comparator. A running motor is driven only in a period that the voltage signal exceeds the threshold level voltage.
