Cleaner and suction device

Abstract

Disclosed herein are a cleaner and a suction device. The cleaner includes a main body case, a motor, a suction fan, a cooling fan, a motor housing and a seal. The main body case includes a first inlet, a first outlet, a second inlet and a second outlet. The suction fan moves air along a first flow path extending from the first inlet to the first outlet. The cooling fan moves air along a second flow path extending from the second inlet to the second outlet. The motor housing supports the motor and includes a partition guide. The seal is coupled to the above partition guide and in contact with an inner wall of the main body case. The partition guide and the seal together partition the first flow path from the second flow path.

1 . A cleaner comprising:
 a main body case including a first inlet, a first outlet, a second inlet and a second outlet;   a motor in the main body case;   a suction fan in the main body case and configured to be rotatable by the motor to move air along a first flow path extending from the first inlet to the first outlet;   a cooling fan in the main body case and configured to be rotatable by the motor to move air along a second flow path extending from the second inlet to the second outlet;   a motor housing supporting the motor and including a partition guide; and   a seal coupled to the partition guide and in contact with an inner wall of the main body case, so that the partition guide and the seal together partition the first flow path from the second flow path.   
     
     
         2 . The cleaner of  claim 1 , wherein the seal is along an outer circumference of the partition guide. 
     
     
         3 . The cleaner of  claim 1 , wherein
 the motor housing further includes a motor cover portion surrounding the motor, and   the partition guide extends from the motor cover portion.   
     
     
         4 . The cleaner of  claim 3 , wherein the partition guide extends from the motor cover portion towards the inner wall of the main body case. 
     
     
         5 . The cleaner of  claim 3 , wherein the seal is coupled to an end of the partition guide opposite to the motor cover portion in a direction extending from the motor cover portion. 
     
     
         6 . The cleaner of  claim 1 , wherein
 the motor housing further includes an air guide which the first flow path passes through, and   the partition guide extends from a side of the air guide in a direction in which air flows along the first flow path in response to the rotation of the suction fan.   
     
     
         7 . The cleaner of  claim 1 , wherein
 the motor housing further includes a first housing surrounding the motor and which the first flow path passes through, and   the seal includes a first sealing portion extending from the partition guide to the inner wall of the main body case and a second sealing portion extending from the first housing to the inner wall of the main body case.   
     
     
         8 . The cleaner of  claim 7 , wherein the second sealing portion partitions a space between an outer circumferential surface of the first housing and the inner wall of the main body case from the first flow path. 
     
     
         9 . The cleaner of  claim 7 , wherein the first outlet is between a portion of the main body case in contact with the first sealing portion and another portion of the main body case in contact with the second sealing portion. 
     
     
         10 . The cleaner of  claim 7 , wherein
 the first sealing portion and the second sealing portion are connected to each other, and   the seal further includes a seal hole between the first sealing portion and the second sealing portion to allow the first flow path to pass therethrough.   
     
     
         11 . The cleaner of  claim 1 , wherein the first outlet and the second outlet are spaced apart from each other. 
     
     
         12 . The cleaner of  claim 1 , wherein
 the motor housing further includes a motor cover portion surrounding the motor, and   the first flow path is disposed on an outside of the motor cover portion, and at least a portion of the second flow path is disposed on an inside of the motor cover portion.   
     
     
         13 . The cleaner of  claim 12 , wherein the second flow path includes a first portion passing through the motor and the cooling fan and a second portion passing between the motor and the motor cover portion. 
     
     
         14 . The cleaner of  claim 1 , further comprising:
 a motor driver electrically connected to the motor, wherein the cooling fan is between the motor and the motor driver.   
     
     
         15 . The cleaner of  claim 1 , further comprising:
 a suction port configured to draw in air and foreign substances; and   a dust collector configured to collect foreign substances in the air drawn in from the suction port, and to allow the air drawn in from the suction port to pass through the dust collector to enter the first inlet.
