Definitions

  • Embodiments relate to a passage opening/closing unit of vacuum cleaner.
  • vacuum cleaners are apparatuses, which suck air containing dusts using a suction force generated by a motor mounted within a main body to filter the dust in the main body.
  • the vacuum cleaners may be classified into a canister type cleaner in which a suction nozzle for sucking dusts on a floor is separated from a main body to connect the suction nozzle to the main body using a connection unit and an upright type cleaner in which a suction nozzle is integrated with a main body.
  • the upright type cleaner includes a suction nozzle for sucking air containing dusts while being moved along a floor, a main body rotatably coupled to the suction nozzle and including a suction motor therein, a handle disposed on an upper portion of the main body and grasped by a user during cleaning, and a dust collection unit mounted on the main body.
  • movement wheels for easily moving the main body are disposed on the suction nozzle.
  • a manipulation for allowing the main body to be rotated at a predetermined angle with respect to the suction nozzle is disposed on a rear side of the suction nozzle.
  • the manipulation part is manipulated to allow the main body to be inclined at a predetermined angle with the suction nozzle.
  • the dusts separated from the air introduced into the dust collection unit are stored in the dust collection unit, and the air separated from the dusts is discharged from the dust collection unit. Then, the air is introduced into the main body and disposed from a side of the main body to the outside.
  • the suction nozzle since the suction nozzle performs the cleaning while being moved along the floor, the floor may be cleaned. However, it is difficult to clean a space except the floor, e.g., stairs or a space having a predetermined height.
  • US 2002/092119 (A1 ) relates to vacuum cleaners and more particularly, to an airflow shut-off mechanism for a vacuum cleaner that is convertible for on-the-floor and above-the-floor vacuuming operations.
  • Embodiments provide a vacuum cleaner which is capable of smoothly cleaning a space except a floor as well as the floor.
  • Embodiments also provide a vacuum cleaner in which a suction passage of a first suction unit communicates with a suction motor in case where a floor is cleaned and a suction passage of a second suction unit communicates with the suction motor in case where portions except the floor are cleaned.
  • a passage opening/closing unit of vacuum cleaner comprises: a main body comprising a suction motor for generating a suction force; a first suction unit rotatably connected to the main body; a second suction unit separably disposed on the main body; a first suction passage through which air sucked through the first suction unit flows; a second suction passage through which air sucked through the second suction unit flows, the second suction passage communicating with the first suction passage; an air guide disposed in the first suction unit to communicate with the first suction passage; an opening/closing member for opening or closing the air guide; and a push member disposed in the main body to selectively press the opening/closing member.
  • the second suction unit mounted on the main body since the second suction unit mounted on the main body is separated from the main body, the spaces except the floor can be cleaned using the second suction unit.
  • the second suction unit is mounted on the main body, it is unnecessary to separately store the second suction unit.
  • the air passage within the main body is opened or closed according to whether the second suction unit is mounted on the main body, it is unnecessary to separately manipulate the air passage to open or close the air passage.
  • Fig. 1 is a rear perspective view of a vacuum cleaner according to an embodiment.
  • Fig. 2 is a rear perspective view of the vacuum cleaner according to an embodiment.
  • Fig. 3 is a rear perspective view of the vacuum cleaner from which a section suction unit is separated.

  • the second suction unit when the cleaning process is performed using the first suction unit 20, the second suction unit is mounted on the main body 10. In this state, since the suction hole of the second suction unit is substantially closed by the main body 10, air is not nearly sucked through the second suction unit.
  • the inner passage of the air guides since the inner passage of the air guides is opened or closed corresponding to the rotation of the main body, the inner passage of the air guides may be precisely opened or closed.
  • the air guides may be always maintained in the open state in the sate where the main body is rotated.
