    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 electric blower has an electric motor, a centrifugal impeller rotating by the driving of the electric motor, an end bracket for separating the electric motor from the centrifugal impeller, and a diffuser. The diffuser includes a plurality of diffuser vanes arranged near the outer periphery of the centrifugal impeller, and a flat plate portion which extends between the centrifugal impeller and the end bracket for supporting the diffuser vanes. The flat plate portion has a plurality of guide vanes formed on an opposite surface thereof from the diffuser vanes. A passage is defined by the end bracket, the flat plate portion and the guide vanes so as to return the air flow, discharged from the centrifugal impeller through the diffuser vanes, inwardly of the blower. The end bracket is formed in a substantially convex shape so as to extend away from the flat plate portion of the diffuser, with the end bracket extending from a central portion toward its periphery, thereby defining an opening area of the discharge air flow return passage. A sound absorbing material is arranged in the discharge air flow return passage to absorb sounds from the discharging air flow.

    摘要： A vacuum cleaner comprising a fan motor disposed in a main body case thereof and having a motor with a permanent magnet stator or rotor, and a fan arranged to be rotated by the motor. A dust-collecting chamber collects dust suctioned into the main body case due to the rotation of the fan motor, and a dust-collecting filter causes the dust suctioned into the main body case to be caught in the dust-collecting chamber. A magnetic material adhesion preventing device is provided in a passage through which air flows due to rotation of the fan motor, with the magnetic material adhesion preventing device acting to prevent adhesion of fine dust composed of magnetic materials included in the air flow to a portion in the vicinity of the permanent magnet. As a result, adhesion of fine dust between the rotor and stator can be prevented thereby increasing the service life and the reliability of the vacuum cleaner.
