Definitions

  • Fig. 1 shows a vacuum cleaner unit embodying the invention
  • FIG. 2 shows diagrammatically 'an arrangement inaccordance with the invention
  • Figs. 3 and 4 are other diagrammatic showings of the' invention
  • Figs. 5 and 6 are partial sectional views of different embodiments of the invention; and' Fig. 7 is an end view 01 shown in Fig. 6.
  • Fig. 1 shows a vacuum cleaner unit of the type disclosed in Engberg et a1.
  • the casing of the cleaner unit is designated generally at l and comprises a central cylindrical barrel portion to which are attached end-caps II and I2.
  • the cleaner unit is mounted horizontally above the surface l8, for example a carpet to be cleaned, by means of runners I3.
  • the end caps are removably attached to the cylindrical barrel by means ,of spring clips'orother fastening means.
  • Within the casing I0 is the usual dust bag 9, fan 8 and motor 1.
  • Behind the motor is a filter l6 which-may comprise a plurality of pieces of cloth stretched on a framework, and adjacent and behind the filter is a wire mesh I!
  • the end cap II is threaded to receive a hose coupling l which has a central opening for flow of air into the casing l0.
  • the end cap I 2 is provided with an outlet member generally designated by numeral 24.
  • the outlet member has a part I9 of generally spherical formation in which is the outlet opening it.
  • the edge of the outlet opening I4 is in a plane oblique to the vertical and offset with respect to the center of the outlet member 24, being in the lower part thereof so that air passing through the outlet opening is directed upwardly away from the floor in order to prevent raising dust.
  • the direction of airflow is indicated by the arrows in part ofthe device Figs. 2, 3 and 4.
  • the outlet member is internally' threadedas shown to receive the coupling member l5 whereby the air hose can be connected to the air outlet.
  • a series of grid members provided across opening- -l4.' Such bars are pref erably vertical as shown in Fig. 7 and may have -a stream line cross-section to minimize resistance.
  • Air is drawn by the fan 8 inwardly through 10 cap I I, through ,dust bag 9, past the motor and out through opening it, the air being directed upwardly due to the arrangement of opening II.
  • end cap l2 may be made in accordance with Figs. 2, 3 or 4. Fig.
  • Fig. 3 shows a spherical shaped wall l9 formed integral with the remainder of the end cap.”
  • Fig. 4 shows an oblique opening formed between two horizontally oflfset vertical walls 2
  • FIG. 5 shows a larger opening I4 obtained by suitably forming the upper part of the outlet member.
  • opening 23 may be provided with a surrounding rim having a vertical edge and di- '30 recting the air flowing therethrough horizontally.
  • the member 24 may be turnably mounted in cap l2 so that the air current may be directed in other directions than upwardly.
  • a vacuum cleaner a cylindrical casing having means forsupporting said above a horizontal surface and means in said casing for producing'fiow of air, of an air outlet member in the. end of said. casing having a spherically shaped portion with the convex side the combination with an air inlet opening,
  • a vacuum cleaner the combination with a cylindrical casing having an air inlet opening, means for supporting said casing horizontally above a horizontal surface and means in said casing for producing flow of air, of an air outlet member in the end of said casing having a spherically shaped portion with the convex side thereof facing the outflowing air and having an or bars 25 maybe '5 v opening therein offset with respect to the center of the member for outflow of air.
  • a vacuum cleaner the combination with a cylindrical casing having end caps, one of said caps being formed with an air inlet opening, means for supporting said casing horizontally above a horizontal surface and means in said casing for producing flow of air, of an air outlet.
  • a vacuum cleaner the combination with a casing having an air inlet opening of an outlet member therefor in generally vertical position and having a spherically shaped portion with the convex side thereof facing the outflowing air and having an opening therein, the perimeter of said opening being in a' plane oblique to the vertical.
  • a vacuum cleaner the combination with a cylindrical casing having an air inlet-opening, means for supporting said casing horizontally above a horizontal surface and means in said casing for producing flow of air, of an air outlet member secured to one end of said casing and being disposed substantially wholly within said casing, said member being formed with a single opening substantially unobstructed with respect to air flow therethrough, the perimeter of said opening being in a plane oblique to the vertical so that air passing therethrough is direc'ted upwardly, whereby air may pass through said opening in a direction normal to said plane without being subjected within said opening to a change in direction. of flow.
  • a vacuum cleaner the combination with a cylindrical casing having an air inlet opening, means for supporting said casing horizontally above a-- horizontal surface and means in said casing for producing flow of air, of an air outlet member secured to one end of said casing,
  • said member having an outer threaded aperture I disposed in a vertical plane and a portion extending within said casing formed with a single opening substantially unobstructed with respect to air flow therethrough, the perimeter of said opening being in a plane oblique to the vertical whereby air may pass through said opening in a direction normal to said plane without being subjected within said opening to a change in direction of flow.
