Definitions

  • Embodiments relate to a vacuum cleaner, and more particularly, to a vacuum cleaner in which a structure thereof is improved to improve suction performance.
  • vacuum cleaners are devices that suck air containing dusts using a vacuum pressure generated by a suction motor installed inside a main body to filter the dusts in the main body.
  • a passage for moving sucked air is defined in the vacuum cleaner.
  • the passage may have various shapes from a suction hole of a cleaner body to a discharge part of the suction motor.
  • a suction and flow performances of air within the vacuum cleaner are largely affected according to what extent the bent portions of the passage exist. In detail, when air flows in one direction and a bent degree of the passage is minimized if possible, flow losses may be reduced.
  • a flow direction of air may be curved. That is, the vacuum cleaner according to the related art has a limitation in which the passage is bent at many portions.
  • a cover member for covering at least portion of the main body is disposed on the main body in a state where a dust separation device is coupled. According to the vacuum cleaner according to the related art, when the dust separation device is curved by the cover member, a user does not know whether the dust separation device is coupled.
  • the cover when the cover is normally operated (i.e., is closed) in a state where the dust separation device is not coupled, the user does all that for nothing because the cleaning process is performed in the state where the dust separation device is not provided.
  • a hook structure connected to the main body may be released to separate the dust collection container or open the cover.
  • EP 1 797 809 A2 relates to a robot cleaner having a dust collection unit with a cyclone part generating an ascending rotary air current from the dust-laden air being drawn in through a lower part thereof, separating the dust from the air using a centrifugal force, and discharging the dust-separated air to the lower part through a center part, and a collection part surrounding the cyclone part to receive the dust being centrifugally separated.
  • Embodiments provide a vacuum cleaner which has a passage for easily introducing air sucked within a main body into a dust separation device.
  • Embodiments also provide a vacuum cleaner which has a bent degree of a passage to minimize a curved flow of air sucked into the cleaner.
  • Embodiments also provide a vacuum cleaner in which a dust separation device is easily detached from a main body and whether the dust separation device is mounted is easily known to the outside.
  • Embodiments also provide a vacuum cleaner in which a cover of the cleaner is fixed to a dust collection container to prevent the cover from being opened when a main body is lifted.
  • a vacuum cleaner includes: a main body including an air inflow part; an internal passage through which air introduced through the air inflow part is moved, the internal passage being defined in the main body; a dust separation device detachably coupled to the main body, the dust separation device including a dust separation chamber for separating foreign substances from the air flowing into the internal passage; and a passage formation part disposed between the internal passage and the dust separation chamber, the passage formation part having an inclined surface for changing a flow direction of the air passing through the internal passage.
