BACKGROUND

1. Field

The present discloser relates to a charging device. More particularly, the present discloser relates to a charging device for charging a wirelessly operating robot cleaner and a handy cleaner.

2. Background

Generally, a robot cleaner is charged by a charging device, and then performs cleaning while moving wirelessly. Such a robot cleaner cleans a set region while itself avoiding an obstruction by a set function, or cleans the set region while moving along the set region in response to a received cleaning signal.

Further, a handy cleaner is configured to be grippable, and performs cleaning by a user's manipulation while being gripped by the user after being charged by the charging device. Since the robot cleaner cannot optionally clean a desired place, each home is furnished with the handy cleaner as well as the robot cleaner. The robot cleaner and the handy cleaner are charged as respective charging terminals thereof are connected to charging terminals of the charging device. The handy cleaner may be classified into a wired handy cleaner and a wireless handy cleaner.

Referring toFIG. 1, Korean Patent Publication No. 10-1192540 discloses a charging device1to which a wireless handy cleaner3and a robot cleaner2are connected. The charging device1may receive charging power via a single electric wire to simultaneously charge the wireless handy cleaner3and the robot cleaner2.

Referring toFIG. 2, Korean Patent Publication No. 10-0657736 discloses a technique wherein a robot cleaner2is connected to a charging device5disposed on a wired handy cleaner4. The wired handy cleaner4and the robot cleaner2connected to the charging device5may be simultaneously charged by charging power inputted via a single electric wire. However, the conventional charging devices1and5are problematic in that they are used only for the purpose of providing a charging function to the handy cleaners3and4, and the robot cleaner2.
