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 system comprising:
a cleaner comprising a dust bin, the dust bin being configured to receive dust; and
a cleaner station configured to couple to the cleaner and to remove the dust in the dust bin,
wherein the dust bin comprises:
a dust bin body that has a cylindrical shape and defines an opening at one side thereof, and
a discharge cover rotatably coupled to the dust bin body and configured to cover the opening,

wherein the cleaner station comprises:
a housing,
a coupling part recessed from a surface of the housing and configured to couple to at least a part of the cleaner,
a suction tube disposed in an upward-downward direction in the housing and connected to the coupling part, and
a door coupled to the coupling part and configured to rotate relative to the coupling part,

wherein the coupling part defines:
a main hole configured to communicate with an outside of the housing and an inside of the suction tube, the main hole being defined at a position configured to face the dust bin based on the cleaner being coupled to the coupling part, and
a bypass suction route including a bypass hole that is located below the main hole and in communication with the outside of the housing and the inside of the suction tube, the bypass suction route being free of any structure that prevents airflow through the bypass suction route from flowing, and

wherein the discharge cover is configured to open and close the main hole based on rotation of the door.

2. The cleaner system of claim 1 , wherein the cleaner station further comprises a dust collecting motor accommodated in the housing and configured to generate a suction force for suctioning the dust in the dust bin through the suction tube, and
wherein the door is configured to:
rotate in a first direction relative to the coupling part to thereby open the main hole based on the cleaner being coupled to the coupling part; and
rotate in a second direction opposite to the first direction to thereby close the main hole based on completion of an operation of the dust collecting motor.

3. The cleaner system of claim 1 , wherein the cleaner station further comprises a dust collecting motor accommodated in the housing and configured to generate a suction force for suctioning the dust in the dust bin through the suction tube, and
wherein the dust collecting motor is configured to:
operate for a predetermined first time in a state in which the main hole is opened to thereby provide the suction force to both of the main hole and the bypass hole; and
after operating for the predetermined first time, operate for a predetermined second time in a state in which the main hole is closed to thereby provide the suction force to the bypass hole.

4. The cleaner system of claim 3 , wherein the door is configured to maintain the main hole to be opened for the predetermined first time.

5. The cleaner system of claim 3 , wherein the cleaner station has:
a main suction route configured to carry air containing dust into an internal space of the suction tube through the main hole; and
the bypass suction route configured to carry air containing dust into the internal space of the suction tube through the bypass hole, and
wherein the dust collecting motor is configured to:
based on the main hole being opened, suction air containing dust through both of the main suction route and the bypass suction route, and
based on the main hole being closed, suction air containing dust through the bypass suction route.

6. The cleaner system of claim 1 , wherein the door is configured to:
rotate relative to the coupling part in a direction from a state in which the main hole is closed; and
rotate together with the discharge cover to thereby open or close the dust bin of the cleaner.

7. The cleaner system of claim 1 , wherein a cross-sectional area of the bypass hole is less than a cross-sectional area of the main hole.

8. The cleaner system of claim 1 , wherein the cleaner station further comprises a push protrusion configured to press the discharge cover to thereby open the dust bin based on the cleaner being coupled to the coupling part, and
wherein the bypass hole is configured to face the push protrusion in a direction in which the push protrusion presses the discharge cover.
