Definitions

  • This invention relates generally to vacuum cleaners and, more particularly, to bagless vacuum cleaners.
  • Bagless vacuum cleaners have become very popular over the last several years. This popularity is due in large part to the ease with which dust and dirt can be removed from such vacuum cleaners. In old style cloth bag-containing vacuum cleaners, dust and dirt removal is a difficult and awkward process, frequently requiring the user to extend his or her hand into the cloth bag to physically disengage dust clumps. Vacuum cleaners using disposable liner bags minimize the problems associated with cloth bags, but the use of such vacuum cleaners requires the continuous replenishment and installation of disposable liner bags. (Also, owners of older model disposable liner bag-containing vacuum cleaners often find it difficult to locate a source of properly sized replacement liner bags.)
  • Bagless vacuum cleaners of the prior art have not been fully satisfactory. Most bagless vacuum cleaners have not demonstrated the ability to fully disengage dust and dirt from the vacuum air stream.
  • the invention satisfies this need.
  • the invention is a vacuum cleaner having (a) a chassis having a base unit and a housing unit, the base unit having an air inlet and roller means for moving the vacuum cleaner across a flat surface; (b) an air blower disposed within the chassis; (c) a removable dust extraction and collection unit disposed within the housing unit, the dust extraction and collection unit comprising: (i) an enclosed inlet chamber, the inlet chamber being substantially cylindrical in shape, the inlet chamber comprising a bottom wall, at least one generally vertical sidewall, an upper section, a lower section and an inlet opening, the upper section of the inlet chamber having an air inlet opening through the sidewalls; and (ii) an enclosed outlet chamber disposed concentrically within the upper section of the inlet chamber, the outlet chamber having a bottom wall and a top wall, the top wall having a top wall opening, the sidewalls having a plurality of inlet apertures, the inlet apertures being disposed in a band around the sidewalls of the outlet

  • the band 58 has a width between about 20 mm and about 50 mm, preferably between about 30 mm and about 40 mm.
  • the band 58 defines a median line (not shown) which divides the uppermost apertures 56 from a substantially equal number of lowermost apertures 56.
  • the median line is disposed between about 30 mm and about 100 mm above the bottom wall 50 of the outlet chamber 34, preferably between about 50 mm and about 60 mm above the bottom wall 50.
  • the outlet chamber 34 has an upper section 66 and a lower section 68. Disposed around the sidewalls 54 in the lower section 68 of the outlet chamber 34 is an exterior perimeter edge member 70.
  • the purpose of the exterior edge member 70 is to provide a narrowing of the open annulus 72 between the interior surface 48 of the inlet chamber 32 and the exterior surface 74 of the outlet chamber 34 proximate to the bottom wall 50 of the outlet chamber 34.
  • the exterior edge member 70 has a diameter between about 10 mm and about 60 mm less than the internal diameter of the inlet chamber 32, preferably between about 10 mm and about 20 mm less than the internal diameter of the inlet chamber 32.
  • a cylindrical filter 76 is disposed vertically and concentrically within the outlet chamber 34.
  • the bottom wall 50 of the outlet chamber 34 has an X-shaped wall 77 which projects vertically above the bottom wall 50. This X-shaped wall 77 supports the cylindrical filter 76.
  • such cylindrical filter 76 is made from polypropylene, paper, ceramic or polytetrafluoroethylene having a thickness between about 1.5 mm and about 5 mm.
  • the top wall 52 of the outlet chamber 34 defines a top wall opening 78.
  • the top wall opening 78 is disposed in the center of the top wall 52.
  • the outlet chamber 34 comprises a planar filter 80 disposed across the top wall 78 opening of the outlet chamber 34.
  • planar filter 80 is made from sponge, fibrous polyethylene, fibrous polypropylene or paper, and typically has a thickness between about 5 mm and about 15 mm.
  • FIG 10 illustrates an exploded view of the dust extraction and collection unit 16.
  • the dust extraction and collection unit 16 further comprises an outlet plenum cover 82 for enclosing an outlet plenum 84 which carries air out of the dust extraction and collection unit 16.
  • the outlet plenum cover 82 is sealed to the outlet plenum 84 by a plenum cover seal 86.
  • a handle 88 having a latch mechanism 90 configured to snap into a corresponding recess (not shown) in the chassis 12.
  • the latch mechanism 90 is biased by a latch mechamsm spring 93 to be in an uppermost (latched) position.
  • the latch mechanism 90 can be easily unlatched by depressing an unlatch button 91 which protrudes through the top of the handle 88.
  • the bottom wall 36 of the inlet chamber 32 is hingeably attached to the body portion 35 at a hinge 95.
  • a bottom wall sealing ring 96 is used to seal the bottom wall 36 to the body portion 35.
  • the bottom wall 36 is retained in a closed position by a bottom wall hook latch 98.
  • the hook latch 98 is pivotally attached to the body portion 35 of the dust extraction and collection unit 16. When in the latched position, the hook latch 98 can be disengaged from the bottom wall 36 by the depression of a locking pin button 100.
  • the locking pin button 100 is biased away from the unlatched position by a bottom wall hook latch spring 102.
  • the invention further comprises duct work 92 for serially connecting in fluid communication the air inlet 22 in the base unit 18, the inlet chamber 32, the outlet chamber 34 and the air blower 14.
  • a blower filter 94 is operatively disposed downstream of the air blower 14.
  • such blower filter 94 is a HEPA filter.
  • the blower motor 28 is first engaged so as to activate the air blower 14 and to rotate the floor brush 24 via the brush drive belt 30.
  • the vacuum cleaner 10 is then pushed across a dusty horizontal surface, such as a floor or a rug, using the handle 96 disposed at the top of the chassis 12.
  • the duct work 92 directs the incoming dusty air stream into the inlet chamber 32 in tangential fashion, such that the incoming air stream within the inlet chamber 32 spirals downwardly about the internal surface 48 of the sidewalls 38 of the inlet chamber 32. After the dust-laden air stream swirls into the lower section 44 of the inlet chamber 32, the air stream reverses direction, drops in velocity and proceeds upwardly towards the outlet chamber 34.
  • the air exiting the outlet chamber 34 is then drawn into the blower 14 via the duct work 92.
  • the air is filtered a third time through the blower filter 94.
  • the air is exhausted to the atmosphere. Dust and dirt which collects within the lower section 44 of the dust extraction and collection unit 16 can be easily removed from the inlet chamber 32.
  • the user depresses the unlatch button 91 at the upper portion of the handle. This action depresses the latch mechanism 90 out of the corresponding recess in the chassis 12 and allows the dust extraction and collection unit 16 to be removed from the chassis 12. After removal from the chassis 12, the dust extraction and collection unit 16 is taken to a refuse bin.
  • the locking pin button 100 is depressed on the hook latch 98 to disengage the hook latch 98 from the bottom wall 36.
  • This action allows the bottom wall 36 to pivot away from the body portion 35, thereby opening the inlet chamber 32 and allowing dust and dirt disposed within the inlet chamber 32 to gravitate out of the inlet chamber 32 into the refuse bin.
  • the bottom wall 36 is pivoted back into abutment with the body portion 35 and the hook latch 98 is snapped into place so as to retain the bottom wall 36 against the body portion 35.
  • the dust collection and extraction unit 16 is then reinstalled within the chassis 12, and the vacuum cleaner 10 is again ready for operation.
  • the invention has been found to provide a vacuum cleaner with all the conveniences of prior art vacuum cleaners, but with increased dust removal efficiency and without excessive mechanical complexity and resulting expense of manufacture.
  • the invention further provides a simple and convenient method of removing accumulated dust and dirt from the vacuum cleaner using a unique dust extraction and collection unit having a bottom wall capable of pivotally opening downwardly.
