摘要： A vacuum cleaner wherein a hose, a pipe and a suction nozzle, which are connected to a vacuum cleaner main body incorporating therein a motor fan, are formed with a suction air passage as well as an exhaust air passage for making air exhausted from the motor fan circumfluently flow. The pipe is composed of an inner cylindrical portion having a substantially circular section and forming the suction air passage, and an outer cylindrical portion a part of which is uniformly formed with the inner cylindrical portion and which covers the inner cylindrical portion to form the exhaust air passage. There can be achieved for a light-weighted and slim-sized arrangement of the pipe through which the suction air passage and the exhaust air passage extends without the fear of dust plugging, and a vacuum cleaner of exhaust circumfluently flowing type can be easily put into to practice.

摘要： In an electric blower, exhaust air discharged radially from a centrifugal fan is redirected to a motor drive section by a diffuser and a fan cover. The air passes from a ventilation opening on a motor frame and through a bracket to cool the motor drive section. A portion of the air from the centrifugal fan is bled off through exhaust openings without passing over the motor, whereby this portion remains cooler and cleaner than the air that passes over the motor. Air flows up a wand and then passes over the motor to cool the motor. This air passes through filters before being discharged. The portion of air that is bled off passes along a parallel path in the wand to agitate dirt, and to maintain the wand relatively cool. In one embodiment, some of the bled-off portion is discharged directly without passing along the wand.

摘要： A dust suction head for use in an electric vacuum cleaner, having an air suction port at the bottom of the head. The head has a brush chamber which accommodates therein a freely rotatable brush having blades that extend along the shaft of the rotational brush. The head additionally has an opening and an air passage connected with the opening for taking in and leading fresh air into the vacuum chamber of the cleaner through the brush chamber such that the fresh air passing through the brush chamber impinges on the blades to accelerate the rotational motion of the blades. Thus, the head can obtain a necessary amount of air to rotate the brush at all times, especially when it is brushing a carpet, and maintain its smooth motion on the floor while dusting it.

摘要： In an inventive electric vacuum cleaner, a filter 20 through which air discharged from an air outlet port 19 is passed is provided on a rear face of a casing 18 of a cyclonic dust collecting apparatus 7, and held by a filter holder 18B. A rear face of the filter 20 is spaced from vertical ribs 32A of the filter holder 18B to define a guide passage 35 for guiding air discharged from a portion of the air outlet port 19 not opposed to an opening 33 through the filter 20 toward the opening 33. The guide passage 35 allows the air to pass through the portion of the air outlet port 19 not opposed to the opening 33.
