Surface cleaning apparatus

Abstract

A surface cleaning apparatus has an air treatment member comprising a collection chamber, a lid, an air inlet and an air outlet. The lid is moveable from a closed position in which the collection chamber is closed and an open position in which the collection chamber is open. A bag is positionable in the collection chamber when the lid is open. The lid comprises the air treatment member air inlet whereby, when the bag is positioned in the collection chamber and the lid is closed, the collection chamber is downstream from the dirty air inlet and at least a portion of the air treatment member air inlet is positioned above an upper end of the bag.

1 . A surface cleaning apparatus comprising:
 (a) an air flow path from a dirty air inlet to a clean air outlet with a motor and fan assembly positioned in the air flow path; and,   (b) an air treatment member comprising a collection chamber, a lid, an air inlet and an air outlet,   wherein the lid is moveable from a closed position in which the collection chamber is closed and an open position in which the collection chamber is open, and   wherein a bag is positionable in the collection chamber when the lid is open, and   wherein the lid comprises the air treatment member air inlet whereby, when the bag is positioned in the collection chamber and the lid is closed, the collection chamber is downstream from the dirty air inlet and at least a portion of the air treatment member air inlet is positioned above an upper end of the bag.   
     
     
         2 . The surface cleaning apparatus of clause  1  wherein the air treatment member air inlet is located in a sidewall of the lid. 
     
     
         3 . The surface cleaning apparatus of clause  2  wherein the air treatment member air inlet comprises a tangential air inlet. 
     
     
         4 . The surface cleaning apparatus of clause  1  wherein the air treatment member air inlet extends through a sidewall of the lid. 
     
     
         5 . The surface cleaning apparatus of clause  4  wherein the air treatment member air inlet comprises a tangential air inlet. 
     
     
         6 . The surface cleaning apparatus of clause  1  wherein the lid comprises an upper wall of the collection chamber and the air treatment member air inlet extends through the upper wall. 
     
     
         7 . The surface cleaning apparatus of clause  6  wherein air treatment member air inlet extends generally downwardly through the upper wall and comprises a tangential air inlet. 
     
     
         8 . The surface cleaning apparatus of clause  6  wherein air treatment member air inlet extends generally downwardly through the upper wall and has comprises a hooked air outlet portion. 
     
     
         9 . The surface cleaning apparatus of clause  1  further comprising a bag retaining member. 
     
     
         10 . The surface cleaning apparatus of clause  9  wherein the bag retaining member comprises a vacuum line. 
     
     
         11 . The surface cleaning apparatus of clause  9  wherein the bag retaining member comprises a mechanical retaining member for a lower portion of the bag. 
     
     
         12 . The surface cleaning apparatus of clause  1  wherein, when the bag is positioned in the collection chamber and the lid is closed, an outlet end of the air treatment member air inlet is positioned above an upper end of the bag. 
     
     
         13 . The surface cleaning apparatus of clause  1  wherein an outlet end of the air treatment member air inlet is non-circular. 
     
     
         14 . The surface cleaning apparatus of clause  13  wherein the outlet end of the air treatment member air inlet is polygonal. 
     
     
         15 . The surface cleaning apparatus of clause  13  wherein the outlet end of the air treatment member air inlet is oval. 
     
     
         16 . The surface cleaning apparatus of clause  13  wherein an inlet end of the air treatment member air inlet is circular.
