Definitions
- This invention relates to a floor tool for an apparatus for cleaning a floor surface and/or such an apparatus including the floor tool.
- this invention relates to an apparatus which utilises a source of suction to draw dirt and/or debris from a floor surface being cleaned for storage in a dirt chamber or bag for emptying by a user.
- Such apparatus are typically known as "vacuum cleaners”.
- the performance of vacuum cleaners is judged on a number of parameters which includes how efficient a cleaner is in extracting dirt/debris for a given suction power, i.e. energy efficiency, and how much noise is generated during use. In order to maximise these efficiencies it is advantageous to reduce suction losses in the suction air flow path and to reduce turbulence in the suction air flow path.
- Known vacuum cleaners have a floor tool which has a chamber having a chamber inlet through which dirt/debris entrained air enters the tool and flows towards the dirt chamber.
- the chamber inlet has a small cross-sectional area compared to the chamber.
- the suction air flow rate through the inlet and chamber is the same and so the limited inlet cross-sectional area means that the suction air flow has a higher velocity near the inlet in comparison to areas upstream of the inlet.
- a housing having an interior surface that defines a chamber for receiving at least a portion of a cleaning member, the housing including:
- housing is formed of at least two housing portions which provide said interior surface and all of said housing portions are permanently connected or permanently joined to each other.
- a housing including:
- a floor tool for an apparatus for cleaning a floor surface said apparatus including a source of suction, the floor tool including:
- a housing including: a floor facing surface having an inlet for receiving dirty air; and
- side A and/or side B forms an angle of between 1 10° to 122° with respect to side C.
- a floor tool for an apparatus for cleaning a floor surface said apparatus including a source of suction,
- a floor tool for an apparatus for cleaning a floor surface said apparatus including a source of suction;
- a floor facing surface of the floor tool includes forward and rearward portions which define respective portions of the periphery of an inlet for receiving dirty air; and wherein the forward portion and/or rearward portion is wedge-shaped and tapers in thickness in a direction towards the inlet.
- a floor tool for an apparatus for cleaning a floor surface said apparatus including a source of suction, the floor tool including:
- a housing including:
- a cleaning member including cleaning elements having respective distal portions which extend through the chamber inlet so as to engage a floor surface during use; at least one floor engaging support element for supporting the floor tool and for spacing, at a predetermined distance, the chamber inlet from the floor surface,
- each of a plurality of the cleaning elements extends further away from the chamber inlet than the pre-determined distance.
- cleaning apparatus including one or more or all of the features of any one of the first, second or fifth to sixth aspects of the invention, and/or including one or more or all of the features set out in the dependent claims relating to any one of the first, second or fifth to sixth aspects of the invention.
- cleaning apparatus including one or more or all of the features of any one of the first to third or fifth and sixth aspects of the invention, and/or including one or more or all of the
- a surface cleaning apparatus including one or more or all of the features of any one of first to fourth or sixth aspects of the invention, and/or including one or more or all of the features set
- Figure 1 is a perspective view of an apparatus for cleaning a floor surface in accordance with the present invention
- Figure 3a is a rear perspective view of a floor tool of the apparatus of figure 1 ;
- Figure 3b is an underside view of a floor tool of the apparatus of figure 1 ;
- Figure 6 is a second side view (opposite to figure 4) of a floor tool of the apparatus of figure 1 ;
- Figure 7 is a perspective view of another component part of a floor tool of the apparatus of figure 1 ;
- Figure 12 is a cross-sectional side view of a component part of a floor tool of the apparatus of figure 1 with a cleaning member removed thereform;
- the housing 16 extends in a direction transverse to the normal direction of movement of the apparatus 10 with the chamber outlet 26 being positioned at one of the transversely remote ends thereof, to the side of the main body 17.
- the outlet 26 extends in a rearward direction towards the upright part 12 and has a connector formed thereon for connection to a hose of the apparatus 10 so as to provide fluid communication between the chamber 20 and the source of suction.
- the housing 16 is generally cylindrical in shape with the cleaning member 22 being positioned along an elongate axis thereof.
- the cleaning member 22 is a brush bar which is rotatably supported at one end of the interior part of the housing 16 and at the other end has a drivable portion 38.
- the drivable portion 38 of the cleaning member 22 extends outside of the chamber 20 (see figure 9).
- the floor tool 14 includes a driving device 40, in the form of a motor positioned in the main body 17, for effecting rotation of the cleaning member 22.
- the device 40 is connected to the drivable portion 38 which is positioned outside of the chamber 20 by a belt in a manner which is known in the art and so is not described in further detail here. Other types of driving connection could be utilised.
- the housing 16 further includes a closing member 42 in the form of a plate-like member which is removably connectable to the side wall 36 and co-operates with the cleaning member 22 so as to substantially seal the remainder of the opening 34 in a fluid tight manner.
- the closing member 42 separates the chamber 20 from the drivable portion 38 of the cleaning member 22 to prevent ambient air flow into the chamber 20 via the opening 34.
- the closing member 42 includes two closing member parts 44, 46 which engage each other at respective ends thereof. The respective ends include a recess 45, 47 through which at least a portion of the cleaning member 22 is received.
- the floor tool 14 includes a removable cover member 48 which, together with the housing 16, forms a space 50 for receiving the drivable portion 38 of the cleaning member 22.
- a substantially disc shaped support member 52 Positioned between the closing member 42 and the cover member 48 is a substantially disc shaped support member 52.
- the support member 52 has a central aperture through which a spindle of the cleaning member 22 extends and is rotatably supported thereby.
- the housing portions 28, 30 each have a respective threaded projection 51 a, 51 b which is long enough to extend through a respective aperture 53a, 53b, 53a', 53b' of the closing member 42 and the support member 52.
- the cover member 48 has apertures 49a, 49b that align with the threaded projections 51 a, 51 b and through which a user can pass through screws or the like to screw them within the threaded projections 51 a, 51 b so as to fix the cover member 48, support member 52 and the closing member 42 to the housing 16.
- the housing portions 28, 30 are ultrasonically welded to each other about their respective perimeters such that the chamber 20 is substantially sealed in a fluid tight manner at this connection.
- Each of the portions 28, 30 are formed by moulding of Acrylonitrile Butadiene Styrene (ABS). In embodiments, other materials such as polypropylene, polycarbonate and/or die-cast aluminium may be used.
- the housing may be formed of a unitary construction, i.e. as a one-piece component. This could be achieved by, for example, 3-D printing or other manufacture methods known in the art.
- the connection may take other forms such as a permanent screw-threaded connection.
- the housing may be formed of more than two parts and/or only a portion of the connection between the parts is permanently made.
- the cleaning member 22 rotates to engage with carpet piles of the floor surface S so as to loosen dirt present therein.
- the dirt is then entrained in the suction air flow.
- the dirt entrained air enters the chamber 20 through the chamber inlet 24 and the dirt is separated and collected in the dirt chamber, with the clean air being exhausted to atmosphere.
- a user removes the cover member 48 by unscrewing the screws passing therethrough to provide access to the space 50 in which the drivable portion 38 of the cleaning member 22 is positioned.
- the user removes the support member 52 and pulls the closing member parts 44, 46 in an upward and downward direction respectively away from the cleaning member 22.
- Laterally facing sidewall 36 and the opposing laterally facing sidewall 37 each have a respective passage 54, 55 which extends away from the inlet 24 in a direction transverse to the normal direction of movement of the apparatus 1 0.
- Each passage 54, 55 is identical and so for the purpose of this description, only passage 54 will be described.
- a portion of the passage 54 has a cross-section which is substantially trapezoidal in that the portion has sides A, B which are relatively short, and a side C which is relatively long.
- the portion of passage 54 is in the form of a recess which is open in a direction towards the floor surface.
- the recess is substantially closed by the floor surface S during use and thus the fourth side of the trapezoid is the floor surface S.
- the portion of passage 54 thus has an open side D opposite side C, and which is longer than side C, whilst sides A and B are relatively short in comparison to D.
- Side A forms an angle a with respect to side C
- side B forms an angle ⁇ with respect to side C.
- a and/or ⁇ is between 1 1 0 ° to 1 22 ° , and more preferably 1 1 6 ° .
- C extends a distance of between 1 8 and 24mm, and more preferably, extends a distance of 21 mm. Improvements in performance have also been found if D is between 20 and 26mm, and more preferably, D is 23mm or about 23mm.
- the portion of passage 54 may not be formed as a recess but rather as a trapezoidal aperture formed in side walls of the housing and configured to have the shape described above.
- Floor facing surface 32 of the floor tool 14 which defines the inlet 24 is positioned in a first plane 56 and a planar portion 58 of the floor facing surface 32 which is positioned forwardly (in normal use) of the inlet 24 subtends an angle ⁇ of 5 to 1 0 ° with respect to the first plane 56. I has been found that performance is unexpectedly improved if ⁇ is in this range. More preferably, it has been found that an angle of 7° B highly advantageous.
- the floor facing surface 32 also includes a substantially flat portion 60 which extends between the planar portion 58 and the inlet 24. The flat portion 60 is positioned in a second plane 62 which is substantially parallel with the first plane 56.
- the cleaning member 22 is arranged to have cleaning elements 68 which each extend radially away from an elongate axis of the cleaning member 22.
- the cleaning elements 68 are elongate and made from a standard material such as nylon or the like.
- the cleaning elements 68 are positioned in a helical pattern on the surface of the cleaning member 22.
- Each cleaning element 68 may be made of a plurality elements which are closely packed together. All that is required is that one or more cleaning elements extend radially away from the elongate axis of the cleaning member and are positioned thereon. In other embodiments the cleaning elements could be arranged in other patterns on the cleaning member.
- the cleaning elements 68 extends further away from the chamber inlet 24 than the distance X. In use, this arrangement ensures that the cleaning elements 68 extend a further distance into the carpet piles of the floor surface S than the support elements 72, 74. Thus, the cleaning elements 68 can agitate and loosen dirt/debris which may be lodged deep within the carpet piles and not otherwise accessible for cleaning. It has been found to be advantageous for the cleaning elements 68 to extend at least twice as far away from the chamber inlet 24 than the pre-determined distance X and more advantageously for the cleaning elements 68 to extend a distance Y of between 0.7 to 1 .3mm away from the chamber inlet 24, and more preferably a distance of 1 mm. It has been further found to be advantageous for the support elements 72, 74 to extend a distance X of between 0.3 to 0.7mm and more advantageously a distance of 0.5mm.
- the floor facing surface of the floor tool 14 includes forward and rear portions 64, 66 which define respective portions of a periphery of the inlet 24. In particular, they define sides of the inlet 24 which extend in a transverse direction to the normal direction of travel of the apparatus 10 in use.
- the forward portion 64 and rearward portion 66 are substantially wedge-shaped and taper in thickness as they each extend towards the inlet 24. It has been found that having such wedge-shaped portions is advantageous with respect to performance in comparison to portions which are curved or include a curved portion.
- FIG. 13(a) shows an embodiment for which the forward portion 64 has an upwardly facing surface 80 and a downwardly facing surface 82.
- the upwardly facing surface 80 tapers towards the floor surface S as it extends in a direction towards the downwardly facing surface 82.
- the forward and rearward portions 64, 66 need not be identical and may each take any of the configurations described above and any combination thereof. It will be appreciated that the features described in relation to embodiments having one or more aspects of the invention are not necessarily features required in relation to the other of the one or more aspects of the invention as will be understood by those skilled in the art. It will also be appreciated that the invention need not be limited to a floor tool that forms part of an upright floor cleaning apparatus. For example, the invention could be embodied on a floor tool which connects to a wand of a cylinder cleaner or the like. The apparatus may also be a wet cleaning apparatus. Furthermore, the cleaning member described with reference to one or more of the embodiments need not be driven by a motor and could be, for example, driven by a wind-turbine.
