Definitions

  • This invention has for object an improvement to an apparatus specifically a vacuum cleaner and relative filter.
  • the invention finds particular even if not exclusive application in the sector of electrical appliances for cleaning of surfaces in various environments, and at the same time as an air purifier.
  • vacuum cleaner apparatuses are well known.
  • the more traditional ones may be composed essentially of an external coat or body, supported by feet or rotating wheels, inside of which body is a power unit consisting of a suction motor or vacuum pump.
  • the said pump by suctioning through a nosepiece handhold by the user, the external air which is in proximity to the surfaces being treated, allows, depending on necessity, the cleaning of dust from carpets, mats, reedmatting, and similar articles.
  • the air so suctioned by the pump is first passed through at least one filter, which generally consists of the dustbag itself, and then once filtered is returned to the surrounding environment.
  • the dustbag-filter is made of a particular type of fine- meshed cloth, allowing in such a way the flow of the suctioned air, but retaining inside the large dust particles and grit generally.
  • the said apparatus consists always of a movable body to which is attached a motor suction unit, and inside of which body is a reservoir that contains water.
  • the air together with the water distributed by a delivery device attached to the nosepiece, is successively suctioned and then introduced to the interior of the said reservoir.
  • a type of perpendicular fan being placed in connection with the exit hole of the suctioned air, by rotating creates a vacuum, which whilst obstructing the entry of the dust, at the same time agitates both the water and the air.
  • a precipitation of the dust in the water discharging to the surrounding environment only air purified from such residues.
  • the aim of the present invention is to realise an improvement to the patent application, "IT-TV91A000117", and also to remedy the possible drawbacks noticeable in it.
  • Figure 1 represents a view in perspective and from the lower side, of an air filter to be utilised inside the vacuum cleaning apparatus.
  • Figure 2 represents a view in perspective of a component, the first filtration device, in particular the air distribution device.
  • Figure 3 represents a view from below of the component of the previous Figure.
  • Figure 4 finally, is represented the internal part of a vacuum cleaning apparatus, in which is used the filter of Figure 1. and the filtration device illustrated in the two successive Figures.
  • an apparatus (A) specifically a vacuum cleaner and air purifier, is composed essentially of a body (1) which supports a suction unit (2).
  • the suction unit (2) of the known type, provides for a vacuum pump which creates a vacuum in the underlying area, in such a way conveying to the inside of the apparatus(A) the air mixed with the dust removed and collected from the exterior by the user through the corresponding and noted nosepiece ( 6).
  • the nosepiece for the collection of the external air (6) is connected to a coupling (6') keyed to the container, on which in turn a manifold (6'') joins to provide a duct that conducts directly, through an aperture (10) made on the bottom of the distribution device(8), to the first filtration device.
  • the air distribution device (8) is composed, more particularly, of a structure, preferably made of a plastic material, and similar in shape to a small upturned basin, the base of which forms a dome (8') whilst the walls (8'') of the basin perimeter are arranged almost parallel with and in proximity to the internal walls of the water reservoir (5).
  • the walls (8'') are almost submerged and have multiple longitudinal holes (9) through which flows, all around the small basin (8), the air so introduced.
  • the air, sucked through the nosepiece (6) is introduced directly into the small domed basin (8) which, being partially submerged, will allow the air to flow in the direction of the following filter (4), first passing peripherally under the level of the water provided (5).
  • the filter (4) rests on the air distribution device (8) which is partially submerged in a reservoir containing water (5) which can be topped up or replaced depending on necessity, by way of the appropriate means provided for this purpose.
  • the filter (4) has a cylindrical section at least equal in diameter to that of the water reservoir (5), and is placed with one side in contact with the dome (8') of the said small basin (8) upturned in the reservoir. (3).
  • the structure of the filter (4) consists of a mesh of interwoven fibres, preferably coconut fibre but not excluding synthetic fibres, obtained by way of a moulding process. The said process provides substantially for the preparation of a slurry composed of filamentous coconut fibres and of a binder, which may be glue. The whole is then cast into a mould and relative counter-mould, eventually undergoing thermoforming, after which it will be extracted, and finally dried.
  • the structure of the filter (4) thus obtained is such as to provide a smooth upper side , on which, extending along the perimeter for some centimetres, are dug out perpendicularly two diametrically opposed recesses (7) that allow for the insertion of fingers to extract the filter (4) from the machine body (1).
  • the underside (4') of the filter (4) provides an area expressly shaped for housing at least partially the duct (6'') joining the suction tube (6) with the distribution device(8).
