Abstract

A cyclone separator-type vacuum cleaner. The vacuum cleaner has a cylindrical housing having three sections. Each section of the housing is joined to an adjacent section by latches provided on the housing. By releasing the latches the internal mechanisms of the vacuum cleaner can be easily accessed for cleaning or maintenance. The vacuum cleaner has a first baffle that is funnel-shaped and a second baffle in the form of an outwardly-flared skirt member. The skirt member is attached at the base of the funnel-shaped baffle. The two baffles together form an exhaust path through their center through which the incoming air exits after the dirt has been separated therefrom. The funnel-shaped first baffle directs the incoming dirt-laden air inwardly in a circular path of decreasing cross-sectional area so that the speed of the circulating air is increased, causing centrifugal separation of dirt. Thereafter, the outwardly-flared skirt member redirects the incoming air outwardly and away from the exhaust path formed through the center of the baffles so that further separation of the dirt will occur prior to exhausting the air through the exhaust path.

Claims

1. A cyclone separator for a central vacuum cleaning system comprising:

a housing having tangential inlet means and exhaust outlet means, said inlet means directing the incoming dirt-laden air in a circular path so as to provide centrifugal separation of dirt from the incoming air;

suction means mounted in said housing for drawing the dirt-laden air through said inlet means;

first baffle means mounted in said housing adjacent to said tangential inlet means and communicating with said suction means, said first baffle means being funnel-shaped, its walls being downwardly and inwardly inclined so as to direct the incoming dirt-laden air inwardly in a circular path of decreasing cross-sectional area, said first baffle means terminating at its lower end in a vertical cylindrical outlet member; and

second baffle means including a vertical sleeve member telescopically connected to the vertical cylindrical outlet member of said funnel-shaped first baffle means, said first and second baffle means together forming an exhaust path through their center and leading to said exhaust means, said second baffle means additionally comprising an outwardly-flared skirt member connected to the base of said vertical sleeve member, said skirt extending toward the walls of said housing so as to redirect the descending circulating air outwardly toward the walls of said housing thereby channeling the circulating air away from the exhaust path provided through the center of said first and second baffle means so as to permit further separation of dirt prior to exhausting the circulating air through said exhaust means.

2. A cyclone separator as defined in claim 1 further comprising a screen placed over the opening to said exhaust path provided through the center of said first and second baffle means.

3. A cyclone separator as defined in claim 1 further comprising a support flange mounted to said housing, said support flange being adapted to be mounted to a wall or other support.

4. A cyclone separator as defined in claim 1 wherein said housing comprises a vertical cylinder having three sections, each section being joined to an adjacent section by latches provided on said housing.

5. A cyclone separator as defined in claim 4 wherein said suction means comprise a motor-driven suction fan mounted in the uppermost section of said cylindrical housing.

6. A cyclone separator as defined in claim 5 wherein said first and second baffle means are mounted in the middle section of said cylindrical housing immediately below said motor and turbine.

7. A cyclone separator as defined in claim 6 wherein the lowermost section of said cylindrical housing forms a removable dust bin placed below said first and second baffle means.

8. A cyclone separator for a central vacuum cleaning system comprising:

a vertical cylindrical housing having three sections, each section being joined to an adjacent section by latches provided on said housing;

a support plate mounted in the uppermost section of said housing, said support plate having mounted thereon a motor-driven suction fan;

an exhaust conduit attached to the outtake of said suction fan, said exhaust conduit extending through the wall of said uppermost housing section so as to expel the exhausted air exterior to said housing;

first baffle means mounted in the middle section of said housing, said first baffle means having a funnel-shaped configuration so that the space between the wall of said middle housing section and said first baffle means forms a circular path that decreases in cross-sectional area from the outside to the inside;

an inlet conduit, one end of said inlet conduit entering said middle section of housing and terminating in a tangential spout near the top portion of said first baffle means so that the incoming dirt-laden air will be directed into said circular path, thereby providing centrifugal separation of dirt particles from the incoming air;

second baffle means comprising a vertical sleeve member and an outwardly-flared skirt member, said sleeve member fitting telescopically over the base of said funnel-shaped first baffle means, said first and second baffle means together forming an exhaust path through their center, said skirt member redirecting the circulating air outwardly and downwardly along the walls of the lowermost section of said housing, thereby channeling the incoming air away from said exhaust path through the center of said first and second baffle means in order to permit further separation of dirt prior to exhausting said incoming air; and

a screen placed over the opening provided through the skirt member of said second baffle means.
