[Description of dust collection unit]
5 is an external perspective view of the dust collection unit 500 provided in the cleaner body 100 of the first embodiment, and FIG. 6 is a longitudinal sectional view of the dust collection unit 500 shown in FIG.
As shown in these drawings, the dust collection unit 500 includes a cup cover unit 570, a filter unit 550, an inner cylinder unit 530, and a bottomed cylindrical dust cup 501.

  The dust cup 501 is formed of a transparent or translucent resin so that the dust collection state can be visually observed from the outside. As shown in FIG. 5, an inflow port 503 is provided at the front portion of the dust cup 501 to allow an air flow from the suction hose unit 300 (see FIG. 1) to flow into the inner peripheral surface of the dust cup 501.

  Referring to FIGS. 1, 2, and 4, the connection portion 306 of the suction hose portion 300 is viewed from the front so that air flows straight into the inner circumferential surface of the cylindrical dust cup 501 from the tangential direction. The vacuum cleaner body 100 is bent from the center to the right.

  Referring to FIG. 6, the inner cylinder unit 530 includes an upper cup cover 537 that houses the filter unit 550, a lower dust partition 535, and an inner cylinder 533 that connects between them. An opening is formed at the bottom of the cup cover 537 to which the inner cylinder 533 is connected.

  A number of slit-like outlets 533b are formed in the longitudinal direction on the peripheral wall of the inner cylinder 533, and a mesh-like filter (not shown) is disposed at the outlet 533b. The dust partition 535 includes a flange portion 535a having an outer diameter larger than that of the inner tube 533, a large-diameter tube portion 535b surrounding the outer periphery of the flange portion 535a, and a small-diameter tube portion 535c whose lower end is in contact with the bottom center portion of the dust cup 501.

  When the electric blower 106 is operated, as shown in FIG. 7, the air flow flows straight from the suction hose 301 into the dust cup 501 through the connection portion 306 in the inner circumferential tangential direction, and the high-speed swirling air flow into the dust cup 501. Form.

Thereby, the dust contained in the airflow is centrifuged. As shown in FIG. 4, since the dust collecting unit 500 is installed so that the central axis of the swirling airflow to be formed faces the direction of gravity, heavy dust among the centrifugally separated dust is caused by the action of gravity. It is accumulated below 535a (FIG. 6).
Here, the center axis of the swirling airflow of the dust collection unit 500 being directed in the direction of gravity does not require the center axis of the swirling airflow to be directly below, and the dust collection unit 500 is directed to the cleaner body 100 in the vertical direction. It only has to be arranged.

  Moreover, a light thing is filtered with the mesh-like filter arrange | positioned at the outflow port 533b with an air flow. Further, minute dust rises in the inner cylinder 533 through the outlet 533b and is filtered by the filter unit 550.

  The filter unit 550 includes a pleated filter in which a peak and a valley are continuous. The filtered air flow is sucked into the electric blower 106 (FIG. 7) through the outflow duct 571. The dust collection unit 500 collects dust by centrifugal separation, but is not limited thereto. For example, a paper pack may be used to collect dust.

  That is, in Embodiment 1, the airflow in the cleaner main body 100 flows into the dust collecting unit 500 from the suction hose 301 through the connection portion 306 and above the electric blower 106 as shown in FIG.

  The inflowing air flow becomes a swirl flow in the dust cup 501 of the dust collection unit 500. After the dust collection is centrifuged, the air flow rises in the inner cylinder 533, passes through the filter unit 550, passes through the electric blower 106, and enters the lower flow path 138 below the dust collection unit 500. enter.

  Then, the air flow passes through the lower flow path 138, then flows into the rear flow path 139, and is discharged to the outside through the exhaust port 133 while cooling the circuit board K (FIG. 4) in the rear flow path 139. To do. In this embodiment, as shown in FIG. 4, an ion generator P is provided in the rear channel 139, and an air flow is discharged to the outside from the exhaust port 133 together with the ions generated by the ion generator P. It is configured as follows.
