Abstract:
1. A vacuum cleaner comprising: a suction port body for sucking dust-containing air from the outside; a motor-driven blower for generating suction air; and a cyclone part which is disposed between the suction port body and the motor-driven blower and is provided with an inflow port, a swirl chamber, and a discharge port body so that the dust-containing air flowing in through the inflow port is swirled in the swirl chamber, and is discharged from the discharge port body after dust has been separated, wherein a side wall of the swirl chamber has: a substantially cylindrically-shaped cylindrical part connected to the inflow port; and a substantially conically-shaped conical part connected to a lower portion of the cylindrical part, wherein the vertex thereof is located at a lower portion thereof, and a side wall of the discharge port body has: a substantially cylindrically-shaped cylindrical body covered by an upper portion of the cylindrical part of the swirl chamber and having a plurality of pores; and a substantially conically-shaped conical body having a plurality of pores and being connected to a lower portion of the cylindrical body and covered by the cylindrical part of the swirl chamber, wherein the vertex thereof is located at a position which does not reach the conical part of the swirl chamber in the lower portion of the cylindrical part of the swirl chamber, and the vacuum cleaner further comprises: a first opening formed by opening a side wall of the cylindrical part of the swirl chamber such that a lower end of the first opening is nearer to the conical part than the inflow port and the cylindrical body are to the conical part; a second opening formed by opening a part of the conical part of the swirl chamber; a first dust case communicating with the swirl chamber via the first opening; and a second dust case communicating with the swirl chamber via the second opening.
