Dust collector and cleaner having same

Abstract

A cleaner including an intake head to draw in foreign matter, a dust collector connected to the intake head, and a fan configured to generate an intake force within the dust collector. The dust collector may include a housing including an inlet and an outlet that are arranged facing a first direction from the inlet, a rotating body rotatable within the housing, a partition arranged between the housing and the rotating body, a first flow path formed between an inner side of the partition and the rotating body and configured to allow air entering through the inlet to be directed along the first direction, and a second flow path formed between an outer side of the partition and the housing and configured to allow air to be directed along a second direction opposite to the first direction.

1 . A cleaner comprising;
 an intake head to draw in foreign matter;   a dust collector to be connected to the intake head; and   a fan configured to generate an intake force within the dust collector;   wherein the dust collector comprises:
 a housing including an inlet and an outlet that are arranged facing a first direction, 
 a rotating body rotatable within the housing, 
 a partition arrangeable between the housing and the rotating body, 
 a first flow path, formed between an inner side of the partition and the rotating body, configured to allow air entering through the inlet to be directed along the first direction, and 
 a second flow path, formed between an outer side of the partition and the housing, configured to allow air to be directed along a second direction opposite to the first direction. 
   
     
     
         2 . The cleaner of  claim 1 , wherein the partition comprises an end arranged facing the first direction, and the first flow path and the second flow path are arrangeable to be connected at the end. 
     
     
         3 . The cleaner of  claim 2 , wherein the end of the partition is a first end, and the partition comprises a second end opposite to the first end, and the first flow path and the second flow path are arrangeable to be connected at the second end. 
     
     
         4 . The cleaner of  claim 3 , wherein the dust collector further comprises a guide wall extending from the inlet toward the partition to allow the air entering through the inlet to be moved to the first flow path. 
     
     
         5 . The cleaner of  claim 4 , wherein
 the guide wall comprises a first end of the guide wall arranged facing the first direction and a second end of the guide wall arranged opposite the first end of the guide wall, and   the second end of the partition is arrangeable on a downstream side of the first end of the guide wall with respect to the second direction.   
     
     
         6 . The cleaner of  claim 4 , wherein
 the guide wall is arrangeable to be spaced apart from the partition toward a center of the housing, and   the dust collector further comprises a re-inlet formed between the partition and the guide wall to allow the air passing through the second flow path to be moved to the first flow path.   
     
     
         7 . The cleaner of  claim 6 , wherein the dust collector further comprises a radial rib connecting the partition and the guide wall. 
     
     
         8 . The cleaner of  claim 4 , wherein the dust collector further comprises a dust collecting chamber arrangeable on a downstream side from the second end of the partition in the second direction to receive foreign matter in the air moving to the second flow path. 
     
     
         9 . The cleaner of  claim 8 , wherein
 the guide wall is arrangeable within the housing, and   the dust collecting chamber is formed between the housing and the guide wall.   
     
     
         10 . The cleaner of  claim 2 , wherein
 the dust collector further comprises a rotating body motor providing a driving force for rotating the rotating body and a rotating body motor case arrangeable within the housing to protect the rotating body motor, and   the rotating body motor case comprises a through hole allowing air passing through the first flow path to be moved to the outlet.   
     
     
         11 . The cleaner of  claim 10 , wherein the through hole comprises an opening formed at an end with respect to the second direction, and the end of the partition is arrangeable on a downstream side of the opening with respect to the first direction. 
     
     
         12 . The cleaner of  claim 11 , wherein the rotating body motor case further comprises an inclined surface arrangeable on the inner side of the partition to surround the opening, the inclined surface inclined toward the partition along the first direction. 
     
     
         13 . The cleaner of  claim 1 , wherein the partition comprises a support protrusion arrangeable on an outer circumferential surface to be supported by the housing. 
     
     
         14 . The cleaner of  claim 1 , wherein the rotating body comprises a blade having a plurality of wings. 
     
     
         15 . The cleaner of  claim 1 , wherein the inlet and the outlet are arrangeable along a straight line.
