Definitions

  • This invention relates generally to suction cleaners (vacuum cleaners). More particularly, the invention relates to a means by which dust, entrained in the suction airflow drawn by the suction cleaner from whatever is being cleaned, is separated from the suction airflow and retained by the vacuum cleaner for disposal.
  • a suction cleaner when we refer herein to "dust" it is used as a general term to cover all the matter that a suction cleaner might be used to collect, rather than as a literal term referring solely to household or other dust.
  • the matter sucked up by a suction cleaner may include hairs, textile fibres, food particles, and items, particles or debris of organic or inorganic material which might range in size from microns to millimetres or even tens of millimetres.
  • a filtration process i.e. passing the airflow through a filter element which will not pass, and therefore traps, particles greater than a certain size.
  • the filtration may be effected by a dust-collection bag, having porous walls which trap the dust but allow air to flow therethrough.
  • the interior of the bag is in fluid communication with an inlet and the bag is disposed in a chamber or compartment from which an electric motor-driven fan causes a stream of dust-laden air to be delivered to the inlet and, after passing through the bag, to be discharged to the ambient atmosphere (in most cases after further filtration.
  • the inlet communicates with a cleaning head part of the cleaner, in the case of an "upright” cleaner, or a suction hose, in the case of a "cylinder” cleaner, which can be directed to an area requiring cleaning.
  • the filtration principle for dust removal has also been utilised in cleaners of the tank or canister type, wherein an inlet hose communicates with a chamber from which air is drawn through a filter element provided at an exit from the chamber. Usually such an exit is provided at an upper part of the chamber. Separated dust simply falls from the filter element into the chamber to await disposal.
  • More recently suction cleaners have utilised the so-called "cyclonic" principle of separating dust from the airflow.
  • dust separation is effected by the rapid swirling motion of airflow in one or more cyclone devices.
  • a number of cyclone devices may be arranged to have the suction airflow passed successively through a first cyclone device or devices of relatively large size to remove large dust particles from the airflow, followed by a number of cyclone devices of smaller size to remove smaller dust particles from the airflow.
  • a further technique for removing dust from the suction airflow is water filtration, wherein the suction airflow is caused to pass through a bath of water which may contain additives.
  • Such water filtration is effective, but not commonly utilised; water contaminated with separated dust particles has to be emptied at intervals and replaced by clean water.
  • the present invention is concerned with providing for water filtration in a cleaner which is of the tank or canister type, wherein the container in which separated dust is collected is suitable for containing a quantity of water for water filtration.
  • the cleaner is to be used in two different configurations - one in which the cleaner acts as a 'dry' suction cleaner, and one in which it acts as a 'wet' water filtration cleaner - the removable components must be simple to insert, assemble, and remove.
  • a suction cleaner for water filtration comprising:
  • a source of suction communicating with the container for drawing air from the interior thereof at an upper part of the container
  • an airflow-directing member affording a passage extending downwardly from the inlet to the lowermost part of the container to discharge incoming air in the lowermost part, the airflow directing member comprising a first, a second and a third portion,
  • the first portion so that it extends generally horizontally from the inlet, the second portion so that it extends downwardly from the first portion, and the third portion so that it extends generally horizontally from the second portion and configured so that the third portion ends at a position which, in plan view, is remote from the inlet, and arranging, within the container, a baffle member adapted to extend over the outlet of the directing member at a position spaced above the lowermost part of the container, the baffle member being inclined downwardly in the direction of the inlet.
  • a kit of parts for converting a suction cleaner for water filtration comprising:
  • a source of suction communicating with the container for drawing air from the interior thereof at an upper part of the container
  • kit of parts comprising:
  • a third portion extending generally horizontally from the second portion and configured so that the third portion ends at a position which, in plan view, is remote from the inlet;
  • the passage afforded by the directing member may comprise at least one, and preferably each, of a first portion extending generally horizontally from the inlet; a second portion extending downwardly from the first portion, and a third portion extending generally horizontally from the second portion.
  • the third portion may end at a position within the container remote from the inlet.
  • the third passage portion may end generally diametrically opposite the inlet, in plan view.
  • the baffle member may, in the case of a cylindrical container as aforesaid extend across a generally semi-circular part of the container in which the end of the third passage portion lies.
  • the general layout of the baffle member also applies when the container is not generally cylindrical.
  • the baffle member may be inclined downwardly towards a diameter of the container transversely of the inlet thereto.
  • the same general configuration may apply, in which the baffle member is inclined downwardly towards the inlet.
  • FIG 1 is an exploded perspective view of the principal components of a suction cleaner adapted for water filtration in accordance with the invention
  • Figure 2 is a cross-sectional elevation of part of the cleaner shown in figure 1 .
  • the suction cleaner there illustrated comprises a container indicated generally at 10, the container being generally cylindrical with an upright central axis, and having a peripheral wall 12 of cylindrical or slightly frusto-conical form, extending upwardly from a frusto-conical lowermost portion 14 with a flat bottom wall 16.
  • a flat bottom wall 16 At the top of the wall 12, there is an outwardly extending flange and short upstanding wall 18, 20 respectively.

  • a filter element lies in the trough 36 and covers the wall portion 38 with its aperture 38a.
  • the body 40 contains a source of suction, i.e. an electric motor and a fan, for drawing air from the interior of the container 10 by way of the aperture 38a and the filter.
  • the body 40 has a base part 42 which overlies the peripheral part 32 of the filter holder 30, the body 40 being connected to the container 10 by suitable fastening means, e.g. peripherally-spaced clips.
  • the body 40 includes a handle 44, and it is to be understood that there will be provided, as is commonly the case in vacuum cleaners of the general type described, an on-off switch, possibly an indicator light, a further airflow (exhaust) filter, and so forth.
  • the container 10 may be of plastics material, and its nature is such that the lower part of the container 10 is able to retain a quantity of liquid. Indeed, vacuum cleaners of the above described configuration are commonly used as wet/dry cleaners, able to used for sucking up spilled liquids and so forth.
  • the member 50 comprises a generally U- shaped member 52.
  • the U-shaped member 52 is configured for engaging a similarly-shaped recess in a portion of the wall of the container, so as to support a portion of a passage of the airflow directing member 50.
  • the U-shaped member 52 fits in at the lower end of the recess defined by outwardly-displaced wall portion 24 of the container, and supports a tubular assembly of first, second and third passage portions 54, 56, 58 respectively.
  • the first passage portion 54 extends generally horizontally in line with the opening in the inlet 22 to which a suction hose is fitted as indicated at 26.
  • the second passage portion 56 extends downwardly from the first passage portion 54, and a bracing web 60 between the passage portions 54, 56 extends so as to be able to contact the internal surface of the peripheral wall 12 beneath the inlet fitting 22 (and generally aligned with the inlet 22).
  • the first and second passage portions 54, 56 are formed as a single component. In other embodiments, they may be formed separately and installed separately.
