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.

摘要： A vacuum cleaner with panel portion structure which includes an improved panel main body and a blower facility valve body. The panel main body has an exhaust air port and an opening for a blower facility. The blower facility valve body is provided at a lower side of the panel main body and is rotatably supported so as to normally shut the blower facility opening. A first exhaust air passage is formed between the intermediate exhaust air port to the main body exhaust air port. A second exhaust air passage is formed between the intermediate exhaust air port to the blower facility opening. The first exhaust air passage and the second exhaust air passage are changed over by the blower facility valve body. The improved blower facility structure permits the development of a series of vacuum cleaners with and without a blower facility.

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.
