Abstract

The present disclosure provides a home cleaning appliance including a housing having a nozzle, which includes a main suction opening. An airstream suction source is mounted to the housing and includes a suction airstream inlet and a suction airstream outlet. A cyclone main body is mounted to the housing and communicates with the nozzle main suction opening. The cyclone main body includes a first stage separator and a plurality of second stage separators. A dirt cup is connected to the cyclone main body for collecting dust particles separated by the first stage separator and the plurality of second stage separators. An air manifold is mounted to the first stage separator for fluidly connecting the first stage separator to the plurality of second stage separators.

Claims

1. A home cleaning appliance comprising:

a housing comprising a nozzle, including a main suction opening;

an airstream suction source, mounted to said housing and including a suction airstream inlet and a suction airstream outlet, said suction source selectively establishing and maintaining a flow of air from said nozzle main suction opening to said airstream outlet;

a cyclone main body mounted to said housing and in communication with said nozzle main suction opening, said cyclone main body including a first stage separator and a plurality of second stage separators;

a dirt cup connected to said cyclone main body for collecting dust particles separated by said first stage separator;

a plurality of fine dust compartments for collecting dust particles separated by said plurality of second stage separators, said plurality of fine dust compartments coupled to said dirt cup, each fine dust compartment corresponding to one of said plurality of second stage separators;

a plurality of isolated air conduits for fluidly connecting said first stage separator to said plurality of second stage separators, each conduit including a first section disposed longitudinally within said first stage separator and said dirt cup and a second section for directing a volume of partially cleaned air generally tangentially into an inlet of a respective second stage separator;

a perforated tube disposed within said first stage separator and said dirt cup, said perforated tube including a plurality of spaced apart first dividing walls defining said first sections of said plurality of air conduits; and

an air manifold mounted atop said first stage separator, said air manifold including a plurality of spaced apart second dividing walls defining said second sections of said plurality of air conduits.

2. The home cleaning appliance of claim 1, wherein an end section of each first dividing wall is generally contiguous with an adjacent end section of each second dividing wall.

3. A home cleaning appliance comprising:

a housing comprising a nozzle, including a main suction opening;

an airstream suction source, mounted to said housing and including a suction airstream inlet and a suction airstream outlet, said suction source selectively establishing and maintaining a flow of air from said nozzle main suction opening to said airstream outlet;

a cyclone main body mounted to said housing and in communication with said nozzle main suction opening, said cyclone main body including a first stage separator and a plurality of second stage separators;

a dirt cup connected to said cyclone main body for collecting dust particles separated by said first stage separator-and said plurality of second stage separators;

a plurality of isolated air conduits for fluidly connecting said first stage separator to said plurality of second stage separators, each conduit including a first section disposed longitudinally within said first stage separator and said dirt cup and a second section for directing a volume of partially cleaned air generally tangentially into an inlet of a respective second stage separator,

a perforated tube disposed within said first stage separator and said dirt cup, said perforated tube including a plurality of spaced apart first dividing walls defining said first sections of said plurality of air conduits; and

an air manifold mounted atop said first stage separator, said air manifold including a plurality of spaced apart second dividing walls defining said second sections of said plurality of air conduits.

4. The home cleaning appliance of claim 3, wherein an end section of each first dividing wall is generally contiguous with an adjacent end section of each second dividing wall.
