Definitions

  • This invention relates to vacuum cleaners and like devices employing an air-current. More particularly the invention relates to vacuum cleaners and like apparatus employing an air conditioning substance, such as a disinfectant or insecticide and still more particularly to such apparatus comprising, in combination with other parts thereof, a receptacle for holding solid particles of such air conditioning substance in the path of the air current generated in the apparatus.
  • an air conditioning substance such as a disinfectant or insecticide
  • One object of the invention is to provide a receptacle for use in conjunction with such apparatus containing solid material in finely divided or powdered form, such as crystals of disinfectant,
  • insecticide or perfuming materials provision being made for readily applying the receptacle to the vacuum cleaner or other such apparatus in the path of the air stream to cause the air stream to contact the divided material.
  • Other objects of the invention are: to heat the air before passing the same in contact with the solid particles; to provide means for agitating the solid particles while the air is being passed in contact therewith, as by causing the air to whirl in the receptacle or bya mechanical agitator; to provide means whereby the air may become saturated with the vapor from the particles while preventing the solid particles themselves from being incorporated in the air stream; to provide for supplying air to the receptacle after the air has first been passed through the vacuum cleaner and purified; and to provide a relatively simple, dependablehighly efficient and convenient device or combination of the type above indicated.
  • the invention also includes certain other new and original features of construction and combinations of parts hereinafter set forth and claimed.
  • FIG. 1 shows a vacuum cleaner embodying the present invention
  • Fig. 2 is an end elevation thereof
  • Fig. 3 is a longitudinal section through the receptacle
  • Fig. 4 is an end elevation thereof, partly in section
  • Fig. 5 is a side elevation of a portion of a vacuum cleaner showing in section 55 a modified form of receptacle.
  • a vacuum cleaner unit having a barrel 10, to one end of which is secured a bell 11 and to the other end of which is secured a housing 12 containing a motor 40 and a fan 41 driven by the motor to produce a current of air through the cleaner unit in the direction of thearrows.
  • Bell 11 and housing 12 are provided with central suction and blower openings 13 and 14, respectively, in which a couplingmember 15 may be inserted.
  • Said coupling member has an internal bore which is adapted to receive the tapered end of an air hose in a manner well known in the art.
  • a dust bag 42 is removably contained in barrel 10, clamps being provided for releasing bell 11 to remove the dust bag.
  • Barrel 10 may be provided with a pair of runners 44 for the purpose of supporting the same and permitting movement thereof over a surface.
  • a receptacle is mounted in fixed or rigid relation thereon.
  • the receptacle comprises a housing 16 which is preferably of spiral conformation and to which is attached a nipple 17 which is adapted to seat within the bore of coupling 15.
  • the receptacle may be formed of any light material, such as aluminum, cardboard or the like.
  • a screen 18 which may be formed of any convenient material such as wire cloth is placed across the end of nipple 17 at the point of attachment to the housing 16.
  • One wall of the housing 16 is provided with a large opening 19, covered by screen 20 of wire cloth or similar material, which may be soldered or otherwise secured thereto.
  • Adjacent to opening 19 a funnel shaped member 21 is secured as by screws 24.
  • Said member 21 terminates in a connector 22 which is adapted to receive the tapered end of a flexible air hose 23; the receptacle then being connected between the main unit of the cleaner and the hose.
  • housing 16 In the opposite side of housing 16 there is provided an opening 26 which is normally closed by screw cover 27.
  • an insecticide material in solid form is placed within housing 16 through aperture 26 after which cover 27 is replaced.
  • the material is preferably of low surface tension whereby it is easily vaporized by the air current.
  • Paradichlorobenzol or paradibromobenzol crystals may be used for this purpose.
  • the cleaner may be operated in the usual manner, thereby causing air to be drawn in through suction opening 13, passed through the dust bag 42, over the motor 40, through filter 43, and through nipple 17 into contact with the crystals in housing 16.
  • the air stream is caused to whirl around in said housing, due to the spiral form of the housing, agitating the crystals and becoming permeated with the vapor therefrom and is then discharged through screen 20 into hose 23.
  • Screen 18 prevents the crystals from entering the vacuum cleaner and at the same time permits free passage of air.
  • screen 20 is arranged vertically in the plane of movement of the crystals so that the crystals are not forced against said screen by the air currents nor caused to lodge therein.
  • the rigid mounting of the receptacle in the outlet opening assures that the screen is retained in proper position to prevent such lodging of crystals thereon.
  • the agitation of the crystals and the whirling motion of the air insures an intimate contact of the air with the surface of the crystals and accelerates the vaporization thereof. 1
  • a cylinder 29 is shown provided with a nipple 30 for attachment in coupling 15 and a connector 31 for receiving air hose 23.
  • the ends of said cylinder are closed by screens 32 and 33, respectively, which prevent the discharge of the solid particles.
  • a fan 34 which is supported on a shaft 35, carried in bearings in spiders 36 and 3'7.
  • the air in passing through said cylinder causes fan 34 to rotate and to mechanically agitate the various crystals.
  • the air stream accordingly makes an intimate surface contact with the crystals and absorbs a maximum amount of vapor therefrom.
  • the air is purified byrpassing through the dust bag and the filter of the vacuum cleaner before it is applied to the crystals for adsorbing the disinfectant vapor.
  • all are air treating members, the dust bag and filter separating out material by screening, and the crystals giving off an insecticide vapor. They may all be used in combination, with different functions.
  • the dust bag removes dirt
  • the filter removes certain bacteria of nature to permit isolation by screening
  • the crystals serve to give the exhausted air a character such as for killing moths.
  • the air in passing through the vacuum cleaner is heated to a certain extent and thereby heats the surface of the crystals and facilitates the vaporization thereof.
  • the crystals may be stored in the receptacle which may be readily applied to the cleaner whenever it is desired to use the same for disinfecting purposes.
  • the above described receptacle may be mounted at either the suction or blower ports of the cleaner, and a liquid or gaseous material adsorbed in a solid such as infusorial earth may be used in place of the solid crystals if desired.
  • the invention has been described as applied to insecticidal crystals, although it is obvious that other crystals, such as disinfectants or perfumes, may be employed instead of or in combination therewith. Furthermore the device may be operated for the usual cleaning purposes simultaneously with the above if such procedure should prove desirable.
  • a receptacle for solid particles having a spiral housing, means for supplying an air stream thereto, a screen for preventing escape of said particles, means for causing said air stream to pick up the particles in said receptacle and impart a whirling motion thereto, and means for discharging said air stream in a direction at right angles to the incoming air stream.
