Definitions

  • the invention relates to vacuums in general and to cyclonic vacuums in particular.
  • cyclonic motion is imparted via a curved nozzle.
  • These vacuums have their own associated problems.
  • the air inflow passage leads into a nozzle which extends into the cyclonic chamber.
  • the curvature of the nozzle causes the air to hit the side of the wall at an angle, creating cyclonic motion.
  • the body of the nozzle itself extends into the cyclonic chamber, it acts as a physical obstruction to the cyclonic motion of the air. This in turn substantially inhibits and/or destroys the cyclonic motion and slows the flow of the air. As a result, the suction strength of the vacuum is weakened.
  • EP 1523916 corresponding to the preamble of claim 1, relates to a hand held vacuum cleaner with a container for the storage of dirt and debris therein.
  • Swirling may be employed to direct entrained dirt and debris in a desired direction relative to the container to slow the rate with which dirt and debris accumulates on the primary filter and/or to centrifugally remove dirt and debris from the air flow.
  • Mechanised cleaning is employed to shake, scrape or otherwise remove accumulated dirt and debris from the primary filter.
  • the invention is a cyclonic chamber for use in vacuums and other air filtration devices.
  • the cyclonic chamber comprises an apex opposite a base with sidewalls extending therebetween.
  • the cyclonic chamber will preferably be generally parabolic in cross-section or generally tubular in cross-section with a hemi-spherical cap at the apex end.
  • the base contains an outflow passage.
  • a conical filter extends from the outflow passage.
  • the filter and outflow passage are configured so that during operation air cannot pass out of the cyclonic chamber without passing through the filter.
  • An inflow passage is also provided at the apex end of the chamber. The inflow passage and the outflow passage are parallel but not aligned.
  • the interior of the cyclonic chamber is substantially smooth.
  • the smooth interior walls of the cyclonic chamber in combination with the offset relationship of the inflow and outflow passages will cause the air in the chamber to take a cyclonic path between the inflow passage and the filter. Debris entrained in the airflow will be pushed to the exterior of the chamber - away from the filter - by centripetal force. Eddies will form in the cyclonic path proximate the base of the chamber. Debris will escape the airflow there. Debris that escapes will either remain at the base or, depending upon the orientation of the chamber relative to gravity, fall back into the airflow where it will again be directed away from the filter.
  • the curved chamber will comprise a recessed cavity.
  • the recessed cavity will be situated external to the cyclonic airflow path within the chamber.
  • a curved inflow nozzle Positioned within this cavity will be a curved inflow nozzle, said nozzle in turn being in communication with the inflow passage. As the nozzle is positioned outside of the air flow in the chamber, it will not act as a physical obstruction to the cyclonic motion of the air.
  • the invention comprises a cyclonic chamber 1 for a vacuum 2.
  • cyclonic chamber 1 has an apex 3 opposite a base 4 and walls 5 extending therebetween.
  • Cyclonic chamber 1 is either generally parabolic in cross section or generally tubular with a hemi-spherical cap at the apex end.
  • the interior surface 6 of walls 5 and apex 3 are substantially smooth and free of obstructions.
  • Extending inwardly from base 4 is an outflow passage 12, which terminates in an outflow aperture 7 that allows air to exit cyclonic chamber 1.
  • Outflow passage 12 will preferably separate outflow aperture 7 from base 4.
  • Outflow aperture 7 will lead to a fan 8 which will generate suction for vacuum 2.
  • a filter 9 Positioned over outflow passage 12 and outflow aperture 7 and extending into cyclonic chamber 1 is a filter 9.
  • Filter 9 will preferably be conical or parabolic in cross section. The exterior of filter 9 will also preferably be substantially smooth. Any supporting ribs 10 and the like will preferably be on the interior of filter 9.
  • Outflow passage 12, outflow aperture 7 and filter 9 are preferably centrally positioned in cyclonic chamber 1. Filter 9 should be configured and positioned so that air cannot pass from cyclonic chamber 1 to outflow passage 12 without passing through filter 9.
  • inflow aperture 11 is provided proximate apex 3.
  • Inflow aperture 11 is preferably elliptical in cross section. It will be appreciated that although inflow aperture 11 is described herein as if it were a two dimensional opening, it will, of course, have some length, such that inflow aperture 11 is in fact a passage, namely inflow passage 13. These passages - inflow passage 13 and outflow passage 12 - are preferably substantially parallel to, but offset from, one another.
  • Air entering cyclonic chamber 1 via inflow aperture 11 must travel from inflow aperture 11 to outflow aperture 7.
  • the smooth curvature of walls 5 will entrain air and debris that enters cyclonic chamber 1 in a curving path. This path will follows walls 5 from inflow aperture 11 to outflow aperture 7, imparting a cyclonic flow pattern to the air within cyclonic chamber 1.
  • air entering cyclonic chamber 1 is able to change directions gradually across the length of cyclonic chamber 1 instead of changing immediately upon entry into cyclonic chamber 1, the flow of air is not constricted as air enters cyclonic chamber I and airflow remains substantially laminar. This allows air to flow through cyclonic chamber 1 without slowing substantially, which in turn allows more air to flow through vacuum 2 per unit time, thereby enhancing the strength of vacuum 2.
  • base 4 of cyclonic chamber 1 is not obstruction free. It is preferably provided with relatively sharp corners where walls 5 meet base 4 end where outflow passage 12 extends from base 4. Other obstacles may be provided there as well. These will cause eddies to form near base 4. Debris will fall out of the cyclonic airflow in these eddies. Depending upon the position of cyclonic housing I relative to gravity, debris falling out of the airstream will either fall onto base 4 or fall back into the airstream.
  • Cyclonic chamber I should open, preferably at or proximate to base 4, in order to allow any dust and debris that have been collected in cyclonic chamber 1 to be discarded.
  • the fan 8 is positioned immediately downstream from cyclonic chamber 1.
  • multiple cyclonic chambers maybe provided in sequence, such that one or more cyclonic chambers are provided downstream from cyclonic chamber 1, and a fan is provided downstream from all of the cyclonic chambers.
  • cyclonic chamber I is shown in a hand held vacuum. However, it will be appreciated that cyclonic chamber I could be utilized in any conventional vacuum system or air filtration system.
  • the chamber 1 will be constructed in substantially the same manner as discussed above i.e. chamber 1 will be defined by a base 4, apex 3. and a plurality of sidewalls 5 in which a cyclonic airflow will be generated.
  • sidewalls 5 will contain a recess aperture 5a and a recessed cavity 34 will depend from sidewalls 5 at recess aperture 5a.
  • recessed cavity 34 will house an inflow nozzle 33 and the positioning and construction of cavity 33 will keep nozzle 33 substantially exterior to the cyclonic airflow path within chamber 1.
  • cavity 34 will be substantially square or rectangular in shape.
  • inflow nozzle 33 will be in communication with inflow passage 13.
  • Inflow nozzle 33 will further comprise a curved body region 33a having a top surface 33e.
  • Inflow nozzle 33 should substantially fill cavity 34, and should further be positioned such that top surface 33e of nozzle 33 substantially closes the recess aperture 5a of sidewalls 5 to prevent air from entering into recessed cavity 34.
  • Inflow nozzle 33 will further terminate into an aperture 33b covered by a directional valve 33c configured to release the air into cyclonic chamber 1 at an angle that is substantially tangential to the curvature of sidewalls 5 of chamber 1.
  • directional valve 33c will comprise a rubber flap 33d. Rubber flaps are known in the art and often utilized with curved nozzles. See Figure 6A . However, the placement and angled opening of rubber flap 33d is part of the novelty of the present invention, as will be discussed further below.
  • cyclonic chamber 1 with recessed cavity 34 may be utilized with any hand held vacuum cleaner body.
  • vacuum source need not be limited to vacuum cleaners, and that chamber 1 may be utilized with any appropriate high velocity air purification system.
  • air will enter cyclonic chamber 1 parallel to inflow passage 13 and then into body region 33a of inflow nozzle 33.
  • a cyclonic path will be generated as follows. The force of the air moving through body region 33a ofnozzle 33 will cause valve 33c of nozzle 33 to become partially and directionally opened, such that air will exit nozzle 33 at an angle that is substantially tangential to the curvature of walls 5 of chamber 1. The tangential approach of the air to sidewalls 5 will cause the air to travel in a cyclical path amund chamber I and across top surface 33e of nozzle 33.
  • nozzle 33 within recessed cavity 34 of chamber 1, the angled partial opening of valve 33c, and the curvature of sidewalls 5 are all preferred features of the invention that, in conjunction with each other, impart a cyclonic flow pattern to the air within chamber 1.
  • nozzle 33 will only minimally interfere with the flow pattern.
  • the positioning and construction of recessed cavity 33 will keep nozzle 33 substantially exterior to the cyclonic airflow path within chamber 1.
  • top surface 33e of nozzle 33 will substantially prevent air from entering into recessed cavity 34. In this fashion, the cyclonic air flow pattern will be maintained.
  • any gaps between nozzle 33 and walls of chamber 5 will preferably beminimized or eliminated to prevent eddies from forming in these areas and to maintain laminar cyclonic flow.
  • chamber 1 This above-discussed preferred construction of chamber 1 is in contrast to prior art practices, whereby, as mentioned above, the body of nozzle 33 is not kept out of the airflow and thus acts as a physical obstruction to the cyclonic motion of the air. See Figure 6B .
  • the interior surface 6 of sidewalls 5 and apex 3 substantially smooth and free of obstructions and by eliminating any gaps between nozzle 33 and sidewalls 5a cyclical motion can be more efficiently maintained around filter 9. This in turn will prevent dust, debris, and other particles from facing into filter 9 and clogging the same. In this manner, the integrity and life of filter 9 will be preserved.
  • Filter 9 may be identical to the one discussed previously, alternatively filter 9 may comprise pleats 9a to provide for an increased surface area for the passage of air, thereby resulting in a more effective cleansing.
  • Attachments 14 include crevice tools, fixed brushes, and motorized rotational brushes. The addition of any such tool to a vacuum will necessarily weaken the strength of the vacuum because they increase the distance between the exterior of the vacuum and the vacuum source- i.e., the fan.
  • cyclonic chamber 1 is more efficient than comparable cyclonic filters, there will be more vacuum suction available in a vacuum containing cyclonic chamber 1. The net result is that a vacuum containing cyclonic chamber 1 should be better able to provide the necessary suction to effectively operate an attachment than a comparable vacuum containing a convention cyclonic filter.
