Abstract

A charging station is disclosed. The disclosed charging station comprises: a charging member configured to come into contact with a charging terminal of a robot vacuum cleaner to provide power to the charging terminal; a first light emitting member for emitting an infrared signal; and a reflecting member disposed to face the first light emitting member and reflect an infrared signal emitted from the first light emitting member, toward the front and sides of the charging station.

First claim

1 . A charging station supplying power to a robot vacuum cleaner, comprising:
a charging member configured to come into contact with a charging terminal of the robot vacuum cleaner to provide power to the charging terminal; a first light emitting member for emitting an infrared signal; and a reflecting member disposed to face the first light emitting member and reflect an infrared signal emitted from the first light emitting member, toward front and sides of the charging station.

2 . The charging station of claim 1 , wherein the reflecting member is in a conical shape, and
wherein a vertex of the reflecting member is disposed to coincide with a central axis of the first light emitting member.

3 . The charging station of claim 2 , wherein a reflecting surface of the reflecting member comprises a cross-section crossing the central axis including a broken line with slopes of a first slope and a second slope,
wherein the broken line portion of the second slope located farther than the broken line portion of the first slope with respect to the first light emitting member and the second slope is greater than the first slope with respect to the central axis.

4 . The charging station of claim 1 , further comprising:
a housing; a second light emitting member disposed vertically on a substrate coupled to an inside of the housing for emitting an infrared signal toward a front of the charging station; and a guide member disposed on a front of the second light emitting member for guiding a signal transmitted from the second light emitting member in a predetermined direction, wherein the first light emitting member is received in the guide member.

5 . The charging station of claim 4 , wherein the guide member comprises a protrusion which protrudes along a front of the guide member and partitions an infrared signal emitted from a first light emitting member and an infrared signal emitted from a second light emitting member.

6 . The charging station of claim 4 , wherein the guide member comprises a receiving portion in which the first light emitting member is received, and
wherein the receiving portion comprises a cover surface covering a portion of the first light emitting member.

7 . The charging station of claim 5 , wherein the reflecting member is integrally formed with a surface facing the first light emitting member of the protrusion.

8 . The charging station of claim 6 , wherein the receiving portion is connected to an insertion hole formed on a lower surface of the guide member, and the first light emitting member is inserted into the receiving portion through the insertion hole.

9 . The charging station of claim 6 , wherein the guide member comprises a fixing member for fixing the first light emitting member to the receiving portion.

10 . The charging station of claim 1 , wherein the charging member comprises:
a charging terminal; and
a magnetic body.

11 . The charging station of claim 10 , wherein the magnetic body comprises an electromagnet,
wherein the charging station further comprises a processor for adjusting magnetization of the electromagnet by controlling current supplied to the electromagnet, and wherein the processor is configured to, based on the robot vacuum cleaner being positioned adjacent to the charging member for charging, supply current to the electromagnet to magnetize the electromagnet, and based on charging of the robot vacuum cleaner being completed, stop supplying current to the electromagnet and remove magnetization of the electromagnet.

12 . The charging station of claim 1 , wherein the reflecting member is in a polygonal shape, and
wherein a vertex of the reflecting member is disposed to coincide with a central axis of the first light emitting member.

13 . A method of manufacturing a charging station, the method comprising:
aligning a first light emitting member emitting an infrared signal in a receiving portion of a guide member into which the first light emitting member is inserted; communicating the first light emitting member with the receiving portion and inserting the light emitting member into the receiving portion through an insertion hole formed on a lower surface of the guide member; and coupling the first light emitting member to a fixing member formed on the guide member by rotating the first light emitting member in a predetermined direction.
