Abstract

A robot cleaner system includes docking structure to allow a dust discharge port of a robot cleaner to come into close contact with a dust suction port of a docking station without an additional drive device. The robot cleaner system includes a robot cleaner having a dust discharge port, a docking station having a dust suction port to suction dust collected in the robot cleaner, and a docking device to perform a seesaw movement as it contacts the robot cleaner when the robot cleaner docks with the docking station, to allow the dust suction port to come into close contact with the dust discharge port. The docking device includes a link member installed in the docking station in a pivotally rotatable manner, one end having a contact portion to come into contact with the robot cleaner, and the other end having a docking portion defining the dust suction port therein.

Claims

1. A robot cleaner system comprising:

a robot cleaner having a dust discharge port; and

a docking station having a dust suction port to suction dust collected in the robot cleaner and a connecting port communicating with the dust suction port,

wherein, during a dust removal operation, the dust collected in the robot cleaner is removed therefrom by coupling the dust discharge port of the robot cleaner to the dust suction port of the docket station and applying a suction force via the connecting port of the docket station, the suction force is generated by a suction device external to the docking station and the robot cleaner,

wherein the docking station includes a support platform adapted to support the suction device such that the suction device is positioned above the robot cleaner during the dust removal.

2. The system according to claim 1, wherein the docking device comprises a manual vacuum cleaner having a connecting pipe which can be fitted into the connecting port of the docking device.

3. The system according to claim 1, wherein the docking device comprises a link member rotatably mounted to the docking station, and the link member comprises one end having a contact portion to come into contact with an upper surface the robot cleaner, and the other end having a docking portion defining the dust suction port therein.

4. The system according to claim 3, wherein the link member performs a seesaw movement in a first direction when the robot cleaner moves while contacting with the contact portion, so as to allow the dust suction port to come into close contact with the dust discharge port, and also performs a seesaw movement in a second direction when the robot cleaner is separated from the contact portion, so as to space apart the dust suction port from the dust discharge port.
