Benefits of technology
The patent text describes a surface cleaning apparatus that uses a cyclone chamber with a dirt collection chamber. The apparatus tries to keep larger dirt particles like popcorn out of the cyclone chamber to prevent them from reducing the efficiency of the dirt separation. However, some of these larger particles do still enter the cyclone chamber. The text proposes a solution by creating a gap or spacing between the end wall of the cyclone chamber and the sidewall of the cyclone chamber, which may be referred to as a plate. This gap or spacing may be created by having a non-circular shape or by having the plate stepped in the axial direction. This solution allows the larger dirt particles to exit the cyclone chamber without reducing its dirt separation efficiency.
Problems solved by technology
If a sufficient amount of larger dirt particles accumulate in the cyclone chamber, this may reduce the dirt separation efficiency of the cyclone chamber.
However, as the size of the dirt outlet is increased, the dirt separation efficiency of the cyclone chamber may be reduced.
