Abstract

A cleaner system includes a cleaner and a cleaner station that performs a method for removing residual dust. The cleaner station is configured to suction dust stored in the cleaner. Residual dust in the cleaner station after suctioning dust in a dust bin of the cleaner is suctioned through a bypass hole that penetrates an outside and an inside of a suction tube.

First claim

What is claimed is:

1 . A cleaner station comprising:
a housing configured to couple to a cleaner; a coupling part recessed from a surface of the housing toward an inside of the housing and configured to couple to at least a part of the cleaner; a cover opening unit disposed at the coupling part and configured to open a discharge cover of a dust bin of the cleaner; a dust collecting motor accommodated in the housing and configured to generate a suction force for suctioning dust in the dust bin of the cleaner; and a suction tube disposed in an upward-downward direction in the housing and connected to the coupling part, wherein the cover opening unit comprises a push protrusion configured to protrude along an axis of the housing and to face a coupling lever of the discharge cover, the push protrusion being configured to press the coupling lever to thereby open the discharge cover based on the cleaner being coupled to the coupling part, and wherein the suction tube defines a bypass hole that extends through a portion of the suction tube to thereby establish fluid communication between an inside of the suction tube and an outside of the suction tube, the bypass hole being configured to allow dust to flow therethrough.

2 . The cleaner station of claim 1 , further comprising:
a door coupled to the coupling part by a hinge, the door being configured to open in a direction in which the discharge cover is opened to thereby allow an outside of the housing to communicate with the suction tube; and a door arm coupled to the door and configured to move the door, wherein the dust collecting motor is configured to, based on the door being closed, operate for a predetermined time to thereby generate the suction force in a state in which the dust bin is coupled to the coupling part.

3 . The cleaner station of claim 1 , wherein the cover opening unit further comprises a protrusion support coupled to a lower end of the push protrusion and configured to linearly reciprocate together with the push protrusion.

4 . The cleaner station of claim 3 , wherein the coupling part comprises:
a first coupling part that has a shape corresponding to a shape of the dust bin and is configured to support a lower outer peripheral surface of the dust bin; and a second coupling part coupled to the first coupling part, the second coupling part comprising a flat surface configured to support a lower surface of the protrusion support that linearly reciprocates with the push protrusion.

5 . The cleaner station of claim 4 , wherein the protrusion support is configured to reciprocate in a first direction, and
wherein a size of the protrusion support in a second direction perpendicular to the first direction is less than a size of the flat surface in the second direction.

6 . The cleaner station of claim 5 , wherein the protrusion support is configured to move along a movement axis that extends in the first direction through a center of the flat surface in the second direction.

7 . The cleaner station of claim 1 , wherein the bypass hole is configured to, based on operation of the dust collecting motor, guide dust accumulated around the push protrusion to the inside of the suction tube.

8 . The cleaner station of claim 1 , wherein the bypass hole is defined at an upper portion of the suction tube.

9 . The cleaner station of claim 1 , wherein the bypass hole is disposed closer to the coupling part than to the dust collecting motor.
