Cleaner and cleaner system

Abstract

The present disclosure relates to a cleaner and a cleaner system, the cleaner including a dust bin, a suction part configured to guide air into the dust bin, a suction motor configured to generate a suction force so that air is sucked through the suction part, a cyclone part configured to separate dust from air by generating a cyclone flow in the air sucked through the suction part, and a filter part configured to filter air discharged from the cyclone part, in which the filter part includes a filter body disposed in the dust bin and having an outer periphery along which the cyclone flow is generated, and filter holes configured to guide air into the filter body, and in which the air is introduced into the filter body through the filter holes in a state in which the air is inclined in a reverse direction to a flow direction of the cyclone flow generated at an inlet side of the filter hole, thereby preventing hairs from being caught by the filter holes.

         12 . The cleaner of  claim 1 , wherein the cyclone flow includes at least one bent point at which the flow direction changes from a direction in which the cyclone flow flows along an outer side of the filter body to a direction in which the cyclone flow is introduced into the filter body through the filter hole. 
     
     
         13 . The cleaner of  claim 1 , wherein the air passes through the filter hole in a state in which the air is inclined in the reverse direction to the flow direction of the cyclone flow generated at the inlet side of the filter hole. 
     
     
         14 . A cleaner system comprising:
 a cleaner comprising a dust bin, and a suction part configured to guide air into the dust bin; and   a cleaner station comprising a housing in which a coupling part onto which the cleaner is seated and coupled is disposed, a dust collecting part accommodated in the housing and configured to capture dust in the dust bin, a flow path part configured to connect the dust collecting part and a dust passage hole formed in the coupling part, and a dust collecting motor disposed below the dust collecting part and configured to generate a suction force so that the dust is introduced into the dust collecting part through the flow path part,   wherein the cleaner comprises:   a cyclone part configured to separate dust from air sucked by the suction part by means of a cyclone flow generated by a suction force of the dust collecting motor; and   a filter part configured to filter air discharged from the cyclone part,   wherein the filter part comprises:
