摘要： In a vacuum cleaner, both static pressure H data and a variation width ΔH in the static pressure appearing when a suction port is operated are detected from a pressure sensor (8) provided at a rear side of a filter (7) within a main body (2) of the vacuum cleaner; a current variation width Δpbi appearing when the suction port is operated is detected from a current of a nozzel motor (26) for driving a rotary brush (10) stored in a power brush suction port; an air quantity at the suction port is calculated from the current, rotational speed of a fan motor (FM) and static pressure ; command values are newly obtained by performing a fuzzy calculation with the variation width Apbi, static-pressure command value Hcmd ; the variation width ΔH and the static-pressure command value Qcmd ; the variation width Δpbi and static-pressure command value Hcmd ; and also the variation width ΔH and static-pressure command value Qcmd as the input thereto ; the rotational speeds of the fan motor (FM) and nozzel motor (26) are controlled from the result of the command values ; and further optimum air suction force is automatically obtained, depending upon the suction port under use and cleaning floor plane.

摘要： A fan motor (FM,17,38,39) such as a brushless motor and a static pressure sensor (8) are provided on a cleaner main body (2) and a nozzle motor (26) is brush. A kind of a cleaning surface (1) to be cleaned is estimated according to a fluctuation width of a peak value in current of the nozzle motor (26) or a fluctuation width of an output value the static pressure sensor (8). A kind of a suction nozzle is estimation according to a speed and a load current of the fan motor (FM,17,38,39) or a wind amount and a mean value of the output value of the pressure sensor (8). In response to the estimated result of the kind of the cleaning surface (1) to be cleaned and the kind of the suction nozzle, inputs of the fan motor (FM,17,38,39) and the nozzle motor (26) are controlled automatically. The input of the fan motor is adjusted automatically through a detection of a mean value of the peak value in current of the nozzle motor. The wind amount and a static pressure are calculated according to the load current and the speed of the fan motor, and in accordance with this calculation result a speed command of the fan motor is determined.
