Dry vacuum cleaning appliance
First Claim
1. An in-line bagless dry vacuum cleaning appliance, comprising:
- a separator tube comprising an intake connector and an exhaust connector;
a vacuum conduit within the separator tube and extended from the exhaust connector toward the intake connector, the vacuum conduit comprising one or more first vacuum suction apertures and one or more second vacuum suction apertures in fluid communication with the exhaust connector;
a cyclone chamber within the separator tube in fluid communication with the intake connector thereof, the cyclone chamber substantially encompassing the one or more first vacuum suction apertures of the vacuum conduit;
a particle receiving chamber in fluid communication with the cyclone chamber;
an axial cyclone inlet in fluid communication between the cyclone chamber and the intake connector of the separator tube;
a particle separator dividing the particle receiving chamber from the cyclone chamber and forming a first transfer aperture therebetween; and
a filter positioned between the particle receiving chamber and the one or more second vacuum suction apertures.

Abstract
An in-line bagless dry vacuum cleaning appliance having a vacuum conduit within a separator tube, the vacuum conduit having spaced apart first and second vacuum suction apertures communicating with an exhaust connector; a cyclone chamber communicating with an intake connector and encompassing the first vacuum suction apertures for forming a cyclonic flow region between the central vacuum conduit and an interior wall of the separator tube; a particle receiving chamber communicating with the cyclone chamber; an axial cyclone inlet communicating between the cyclone chamber and the intake connector of the separator tube; a particle separator dividing the particle receiving chamber from the cyclone chamber and forming a first transfer gap therebetween adjacent to the interior wall of the separator tube for receiving disentrained particles into the particle receiving chamber from the cyclone chamber; and a filter between the particle receiving chamber and the second vacuum suction aperture.

9. An in-line bagless dry vacuum cleaning appliance, comprising:
-
a separator tube comprising opposing upstream and downstream tube ends each opening into an interior portion of the separator tube; an axial intake connector sealed to the upstream tube end of the separator tube and comprising an axial intake tube for receiving an intake airstream; an axial exhaust connector sealed to the downstream tube end of the separator tube and comprising an axial exhaust tube; an incoming vacuum chamber formed within the separator tube adjacent to the upstream tube end thereof; a continuous central vacuum conduit coupled in fluid communication with the axial exhaust tube of the axial exhaust connector at the downstream tube end of the separator tube, the central vacuum conduit being extended substantially longitudinally through the separator tube from the axial exhaust connector toward the opposite upstream tube end, the central vacuum conduit comprising one or more first vacuum suction apertures adjacent to incoming vacuum chamber and in fluid communication with the axial exhaust connector; a cyclone chamber is formed downstream of the incoming vacuum chamber for forming a cyclonic flow region between the central vacuum conduit and an interior wall of the separator tube adjacent to the incoming vacuum chamber; a particle receiving chamber in fluid communication with the cyclonic flow region wherein a dead air space is formed for retaining particulate material disentrained from the intake airstream; an axial spiral cyclone inlet separating the cyclone chamber from the adjacent incoming vacuum chamber, the axial spiral cyclone inlet communicating between the cyclone chamber and the adjacent incoming vacuum chamber; a particle separator for disentraining particulate material from the intake airstream, the particle separator dividing the particle receiving chamber from the cyclone chamber and the cyclonic flow region and forming a first transfer gap adjacent to the interior wall through which disentrained particulate material may enter the particle receiving chamber from the cyclone chamber communicating therewith; one or more second vacuum suction apertures in fluid communication between the axial exhaust connector and a portion of the particle receiving chamber distal from the cyclone chamber; and a filter positioned between the particle receiving chamber and the one or more second vacuum suction apertures. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16)

17. A method for dry vacuum cleaning and bagless removal of dust and debris from a surface utilizing a fluid cleaning appliance, the method comprising:
-
receiving an intake airstream at least partially laden with heavier-than-air particulate material into a separator tube through an intake connector thereof; through an exhaust connector of the separator tube, applying a negative air pressure to spaced-apart first and second vacuum suction apertures in a vacuum conduit positioned within the separator tube and extended from the exhaust connector toward the intake connector, the spaced-apart first and second vacuum suction apertures being in fluid communication with the exhaust connector through the central vacuum conduit; within the separator tube, receiving the intake airstream into an axial cyclone generating inlet in fluid communication with the intake connector of the separator tube; within the separator tube, receiving the intake airstream into a cyclone chamber that is in fluid communication with the axial cyclone generating inlet and that substantially encompasses the one or more first vacuum suction apertures of the vacuum conduit and is in fluid communication therewith, with the axial cyclone generating inlet, forming the intake airstream into a cyclonic airstream at least partially laden with the heavier-than-air particulate material within a cyclonic flow region in the cyclone chamber between the central vacuum conduit and an interior wall of the separator tube; by centrifugal acceleration of the cyclonic airstream that is at least partially laden with the heavier-than-air particulate material, urging migration of the heavier-than-air particulate material toward the interior wall of the separator tube; receiving from the cyclone chamber a first portion of the airstream separated from the heavier-than-air particulate material through the first vacuum holes of the central vacuum conduit; receiving from the cyclone chamber a second portion of the airstream that is at least partially laden with the heavier-than-air particulate material into a first transfer gap adjacent to the interior wall of the separator tube and in fluid communication between the cyclonic flow region of the cyclone chamber and a particle receiving chamber; receiving from the first transfer gap the second portion of the airstream that is at least partially laden with the heavier-than-air particulate material into the particle receiving chamber; separating the heavier-than-air particulate material and the second portion of the airstream; capturing the heavier-than-air particulate material in the particle receiving chamber; and receiving the second portion of the airstream through the second vacuum holes of the central vacuum conduit. - View Dependent Claims (18, 19, 20)
