    摘要: A controlling apparatus controls a suction performance of a blower motor which is installed into a cleaner main body. The controlling apparatus increases the suction performance when a suction nozzle is operated and decreases the suction performance when the suction nozzle is stopped. Corresponding to a floor use suction nozzle and a crevice use suction nozzle, at a predetermined air flow amount range, the most suitable operation control being suited to a discriminated suction nozzle can carried out automatically. Plural kinds of the suction nozzles at an actual use scope are set beforehand. When the suction nozzle is exchanged the flow amount range is changed over and selected with a respective suction nozzle. Plural kinds of the suction nozzles are selected and changed over automatically according to the dimension of a change amount of an operation condition. A brushless direct motor is used as the blower motor and has a domain being operated at a chopper control duty of factor 100%.

    摘要: An output of a electric driven blower in a cleaner main body is controlled in response to a detection value of a pressure sensor which detects an operation condition in the cleaner main body. A change-over level setting value is provided as a control value for the sensor so as to form a judgment point for changing over a control condition of the blower. A return level setting value is provided as a control value for the sensor so as to form a judgment point for returning to a previous control condition of the blower from a changed-over condition of the blower. When the detection value of the sensor is more than the change-over level setting value, the return level setting value is set higher than the change-over setting value, thereby the output of the blower is increased, or the return level setting value is set a lower than the change-over level setting value, thereby the output of the blower is decreased.
