Cleaner system

Abstract

A cleaner system provided to remove dust from a dust bin of a cleaner is proposed. The cleaner system includes a first station coupled with a first cleaner, and a second station docked with a second cleaner, thus allowing dust to be collected from both a dust bin of the first cleaner and a dust bin of the second cleaner. Further, it is possible to selectively switch a suction path between a first suction path for sucking dust from the dust bin of the first cleaner and a second suction path for sucking dust from the dust bin of the second cleaner according to the opened or closed state of a door without the necessity of adding components for switching the path.

What is claimed is: 
     
         1 . A cleaner system, comprising:
 a first station coupled with a first cleaner, and including a housing that defines a space therein;   a second station disposed under the first station to be coupled with the first station, a second cleaner being docked on the second station; and   an external path disposed outside the first station, and communicating with an interior of the housing and a dust bin of the second cleaner,   wherein the first station further comprises:   an internal path vertically disposed in the housing, and communicating with a dust bin of the first cleaner;   a dust collecting motor disposed in the housing, and generating a suction force to suck dust from the dust bins of the first cleaner and the second cleaner; and   a door disposed on a coupler at which the first cleaner is coupled to the housing, and opened towards an interior of an upper portion of the housing to cause an outside of the housing to communicate with the internal path,   wherein, when a suction force is generated by the dust collecting motor, if any one dust suction path of the external path and the internal path is opened according to an opened or closed state of the door, a remaining dust suction path is closed.   
     
     
         2 . The cleaner system of  claim 1 , wherein the door is disposed to be parallel to a major axis of the housing when the door is closed, and is disposed to face the dust collecting motor when the door is opened. 
     
     
         3 . The cleaner system of  claim 1 , wherein the first station further comprises:
 a door motor providing power to open or close the door;   a first door arm coupled at a first side thereof to the door motor; and   a second door arm coupled at a first side thereof to the first door arm, and coupled at a second side thereof to the door.   
     
     
         4 . The cleaner system of  claim 1 , wherein the first station further comprises an internal extension tube disposed in the housing, and
 the internal extension tube is formed such that a first end thereof is connected to the external path, and a second end thereof is opened in a direction facing the dust collecting motor in the housing.   
     
     
         5 . The cleaner system of  claim 4 , wherein the internal extension tube is disposed such that the second end thereof is disposed above the door when the door is opened. 
     
     
         6 . The cleaner system of  claim 1 , further comprising:
 a dust collecting part accommodated in the housing, disposed above the dust collecting motor, and collecting dust sucked from the dust bin of the first cleaner and the dust bin of the second cleaner by the dust collecting motor.   
     
     
         7 . The cleaner system of  claim 6 , wherein the dust collecting part collects dust through a first suction path connected to the dust bin of the first cleaner, the internal path, and the dust collecting part when the door is opened, and collects dust through a second suction path connected to the dust bin of the second cleaner, the external path, the internal path, and the dust collecting part when the door is closed. 
     
     
         8 . The cleaner system of  claim 1 , wherein the second station is docked with the second cleaner in the same direction as a direction in which the first cleaner is coupled to the first station. 
     
     
         9 . The cleaner system of  claim 1 , wherein the second station comprises:
 a lower body on which the second cleaner climbs to be docked thereon;   a side body connected to each of opposite side ends of the lower body and extending upwards from the lower body; and   an upper body connected to the side body, coupled with the first station, and disposed above an upper surface of the second cleaner to be spaced apart therefrom by a predetermined distance in a state where the second cleaner is docked; and   a rear body connected with the lower body, the side body, and the upper body, and disposed in a direction opposite to a side in which the second cleaner is docked.   
     
     
         10 . The cleaner system of  claim 9 , wherein the housing is provided with a plurality of housing fastening holes formed in a lower end thereof,
 the upper body comprises on an upper surface thereof a plurality of upper body fastening holes disposed at positions corresponding to the housing fastening holes, respectively, and   the housing and the second station are detachably coupled with each other through the housing fastening holes and the upper body fastening holes.   
     
     
         11 . The cleaner system of  claim 9 , wherein the second station further comprises a path support part that is connected to the rear body, extends upwards from the upper surface of the upper body to be spaced apart therefrom by a predetermined distance, and accommodates a portion of the external path therein. 
     
     
         12 . The cleaner system of  claim 9 , wherein the lower body comprises:
 a suction hole formed to correspond to a position where the dust bin of the second cleaner is disposed, in a state where the second cleaner is docked; and   a second cleaner charging terminal electrically connected to the second cleaner and supplying power to charge the second cleaner.
