Definitions

  • the present invention relates to a cleaner station and a method of collecting dust of the cleaner station. More specifically, the present invention relates to a method of collecting dust of the cleaner station, in which a stop position of a rotation plate after a process of compressing dust is finished is always positioned at a side opposite to a stop position in a previous compressing process so that the dust may be evenly distributed to left and right sides of the rotation plate.
  • a cleaner station which is configured to suction and collect dust of the dust bin through a suction force of a dust collection motor to prevent a user from manually removing the dust of the dust bin, is expanding.
  • the first patent document discloses a discharging station docked with a robot cleaner and an embodiment of the discharging station including a canister dust bin in the form of a bin and a dust separator.
  • a dust separator is formed in a cone shape to use the centrifugal separation principle and included inside the canister.
  • dust separated from a multi-stage separation device disposed on an upper portion of the canister is formed to be collected in the canister.
  • the canister dust bin disclosed in the first patent document always generates an airflow therein due to the multi-stage separation device which adopts the centrifugal separation principle, and thus a volume of the collected dust becomes large, resulting in a problem that dust storage efficiency is lower than that of a dust bag.
  • Korean Patent Registration No. 0906848 is presented.
  • the second patent document relates to a vacuum cleaner, and the vacuum cleaner disclosed in the second patent document includes a dust collection unit in which foreign substances are stored, a pressing plate movably provided on a dust collection unit to compress the foreign substances, and a driving motor for moving the pressing plate.
  • the dust collection unit further includes a display unit for displaying an emptying time of the compressed foreign substances when a movement range of the pressing plate is within a predetermined range.
  • the second patent document describes that the rotation range of the pressing plate is measured to display the dust emptying time, but a specific method of measuring the rotation range of the pressing plate is not presented.
  • the dust is compressed by rotating the pressing plate immediately after the dust is collected, and thereafter, a problem that the volume of the dust re-expands as the compressed dust is blown away during the time until the dust is re-collected can occur.
  • the present invention is directed to providing a cleaner station and a method of collecting dust, in which it is possible to increase storage efficiency of collected dust.
  • the present invention is directed to providing a cleaner station and a method of collecting dust, in which it is possible to improve convenience so that a user may flexibly select a removal time when removing dust collected in a collection unit.
