Vacuum cleaner having detection device for sensing and displaying the filling state of a dust bag

摘要

A vacuum cleaner sucks dust with air to a vacuum cleaner body(1) through a suction pipe(4) and collects only dust by a dust bag(2), comprises control section(72) and a generator(71) both being provided within an operation section(7) which is provided at a predetermined position of the suction pipe(4), which generator(71) is driven by an air sucked to the suction pipe(4) from outside through the operation section(7) so as to generate an electric power, and further comprises a collected dust quantity detection and display section(81, 82, 83, 84, 85) included within the control section(72) which compares the generated electric power with a predetermined electric power so as to obtain a comparison result, detects a quantity of dust within the dust bag(2) based upon the comparison result, and displays a detection result of the quantity of dust.
