Description
A Cleaner Head The present invention relates to a cleaner head for a surface treating appliance. In its preferred embodiment, the present invention relates to a cleaner head for a vacuum cleaning appliance.
A vacuum cleaner typically comprises a main body containing dirt and dust separating apparatus, a cleaner head connected to the main body and having a suction opening, and a motor-driven fan unit for drawing dirt-bearing air through the suction opening. The dirt-bearing air is conveyed to the separating apparatus so that dirt and dust can be separated from the air before the air is expelled to the atmosphere.
The suction opening is directed downwardly to face the floor surface to be cleaned. The separating apparatus can take the form of a filter, a filter bag or, as is known, a cyclonic arrangement. The present invention is not concerned with the nature of the separating apparatus and is therefore applicable to vacuum cleaners utilizing any of the above arrangements or another suitable separating apparatus.
A driven agitator, usually in the form of a brush bar, is supported in the cleaner head so as to protrude to a small extent from the suction opening. The brush bar is activated mainly when the vacuum cleaner is used to clean carpeted surfaces. The brush bar comprises an elongate cylindrical core bearing bristles which extend radially outward from the core. The brush bar may be driven by an air turbine or by an electric motor powered by a power supply derived from the main body of the cleaner. The brush bar may be driven by the motor via a drive belt, or may be driven directly by the motor, so as to rotate within the suction opening. Rotation of the brush bar causes the bristles to sweep along the surface of the carpet to be cleaned to loosen dirt and dust, and pick up debris. The suction of air causes air to flow underneath the sole plate and around the brush bar to help lift the dirt and dust from the surface of the carpet and then carry it from the suction opening through the cleaner head towards the separating apparatus.
The bristles of the brush bar are usually formed from nylon. While the use of nylon bristles provides an acceptable cleaning performance on carpeted floor surfaces, we have found that the use of nylon bristles generates static electricity when the floor tool is used on some hard floor surfaces, such as laminate, wood and vinyl surfaces, which attracts fine dust and powders, such as talcum powder, on to the floor surface. This can impair the cleaning performance on the cleaner head on such floor surfaces, as the sweeping action of the nylon bristles is insufficient to overcome the force attracting the fine dust to the floor surface.
In a first aspect, the present invention provides agitating apparatus for a surface treating appliance, comprising a rotatable body having at least one substantially continuous row of electrically conductive surface agitating means extending outwardly therefrom.
Providing the rotatable body with electrically conductive surface agitating means can enable static electricity residing on a floor surface to be cleaned to be discharged upon contact between the agitating means and the floor surface. This enables fine dust and powder which would otherwise be attracted to the floor surface to be dislodged from the floor surface by the agitating means. The agitating means is preferably arranged in at least one substantially continuous row so that no patterns of dirt or dust are formed on the floor surface as each row of agitating means is swept thereover.
The surface resistivity of the agitating means is preferably in the range from lxi 0 to ixiO'2 �=/sq (ohms per square). Values of surface resistivity discussed herein are as measured using the test method ASTM D257. The selection of material having a surface resistivity in this range can ensure that any static electricity on the floor surface is effectively discharged by the agitating means.
The agitating means is preferably formed from one of metallic, carbon fibre, carbon composite or other composite material. For example, material comprising carbon particles and carbon fibres generally has a surface resistivity in the range from 1x103 to 1x106 �=/sq, whereas metallic material generally has a much lower surface resistivity, generally lower than 1 �=/sq. Other static dissipative materials generally have a surface resistivity in the range from 1x105 to lx 1012 c/sq The at least one row of agitating means may be arranged in any desired pattern, or randomly, on the body. In a preferred embodiment, the agitating means is arranged in at least one helical formation along the body.
The agitating means is preferably arranged in a plurality of rows along the body. The agitating means may comprise a plurality of bristles, filaments or one or more other agitating members. For example, the agitating means may comprise at least one strip of material mounted on the body. Where the agitating means comprises a plurality of bristles or filaments, these bristles or filaments are arranged in a closely packed formation so that the, or each, row of bristles is substantially continuous. Where the agitating means comprises at least one strip of material, each row is preferably formed from a single strip of material, or from a plurality of adjoining strips.
Preferably, at least two rows of the agitating means are in electrical contact. In a preferred embodiment, adjacent rows of the agitating means are in electrical contact.
For example, at least one agitating member of one row may also form at least one agitating member of another row. Such agitating members may pass through one or more apertures formed in the rotatable body of the agitating apparatus, or may be otherwise connected to the body so that two rows each comprise a respective end of an agitating member. In a preferred embodiment, a row of bristles or filaments is sandwiched between the rotatable body and a connecting member connected to the body so that the ends of the bristles or filaments protrude from the body to define respective rows of the agitating means. A strip of material may be similarly connected to the rotatable body so that the ends of the strip form respective rows of the agitating means.
This can simplify manufacture of the agitating apparatus, and reduce costs.
In a preferred embodiment the rotatable body comprises further surface agitating means.
The agitating apparatus may thus comprise two different surface agitating means.
Preferably, the electrically conductive surface agitating means protrudes radially outwardly from the body beyond the further surface agitating means. The relatively short, further surface agitating means may be configured to agitate dirt and dust from a carpeted floor surface, whereas the relatively long, electrically conductive surface agitating means may be configured to sweep dirt and dust from a hard floor surface.
The further surface agitating means is thus preferably relatively stiff in comparison to the electrically conductive surface agitating means. For example, bristles or filaments of the further surface agitating means may have a greater diameter than bristles or filaments of the electrically conductive surface agitating means. Alternatively, one or more strips of material forming the further surface agitating means may have a greater thickness than strips of material forming the electrically conductive surface agitating means.
The further surface agitating means may be formed from electrically insulating, plastics material, such as nylon, and so may have a surface resistivity which is different to that of the electrically conductive surface agitating means. The surface resistivity of the further surface agitating means is preferably in the range from lxlO'2 to lxlO'6 �=/sq.
Alternatively, the further surface agitating means may be formed from a similar material as the electrically conductive surface agitating means, and so may have a surface resistivity within the aforementioned range for the electrically conductive surface agitating means, in order to discharge any static electricity residing on a carpeted floor surface.
The further surface agitating means is preferably spaced from the electrically conductive surface agitating means. The further surface agitating means is preferably arranged in a plurality of rows along the body, with these rows being preferably discontinuous. For example, where the further surface agitating means comprises a plurality of bristles these bristles are preferably arranged in one or more rows of clusters or tufts of bristles connected to and spaced along the body. However, the further surface agitating means may be located within, or otherwise in contact with, the electrically conductive surface agitating means. For example, each of the agitating means may comprises a plurality of bristles or filaments, with the bristles or filaments of the further surface agitating means being located adjacent, or amongst, bristles or filaments of the electrically conductive surface agitating means.
Preferably, the electrically conductive surface agitating means protrudes outwardly beyond the further surface agitating means by a distance in the range from 0.5 to 5 mm.
The agitating apparatus is preferably in the form of a rotatable brush bar.
In a second aspect, the present invention provides a cleaner head for a surface treating appliance, the cleaner head comprising a housing and apparatus as aforementioned. The cleaner head preferably comprises a sole plate having a suction opening through which dirt-bearing air enters the cleaner head, and through which the agitating means protrude as the body is rotated during use of the cleaner head, and a plurality of support members, preferably in the form of rolling elements, such as wheels or rollers, rotatably mounted on the sole plate, for supporting the cleaner head on a surface to be cleaned.
In a third aspect, the present invention provides a surface treating appliance comprising a cleaner head or agitating apparatus as aforementioned.
The term "surface treating appliance" is intended to have a broad meaning, and includes a wide range of machines having a main body and a head for travailing over a surface to clean or treat the surface in some manner. It includes, inter alia, machines which simply agitate the surface, such as carpet sweepers, machines which only apply suction to the surface, such as vacuum cleaners (dry, wet and wet/dry), so as to draw material from the surface, and machines which apply material to the surface, such as polishing/waxing machines, pressure washing machines and shampooing machines.
Features described above in connection with the first aspect of the invention are equally applicable to any of the second to third aspects of the invention, and vice versa.
An embodiment of the present invention will now be described, by way of example only, with reference to the accompanying drawings, in which: Figure 1 is a front perspective view of a floor tool; Figure 2 is a rear perspective view of the floor tool of Figure 1; Figure 3 is a rear view of the floor tool of Figure 1; Figure 4 is a sectional view of the floor tool taken along line A-A illustrated in Figure 3 when the floor tool is located on a carpeted floor surface; and Figure 5 is a sectional view of the floor tool taken along line A-A illustrated in Figure 3 when the floor tool is located on a hard floor surface.
Figure 6 is a view of an alternative brush bar for use with the floor tool of Figure 1.
The floor tool 10 of Figures 1 to 5 comprises a cleaner head 12 rotatably attached to a coupling 14. The free end of the coupling 14 is attachable to a wand, hose or other such duct of a cleaning appliance (not shown). The cleaner head 12 comprises a housing 16 and a lower plate, or sole plate 18, comprising a suction opening 20 through which a dirt-bearing fluid flow enters the cleaner head 12. The housing 16 defines a suction passage extending from the suction opening 20 to an outlet duct 22 located at the rear of the housing 16. The sole plate 18 comprises a plurality of support members 24 in the form of rolling elements mounted within recessed portions of the sole plate 18 for supporting the cleaner head 12 on a floor surface. With reference to Figures 4 and 5, the support members 24 are preferably arranged to support the sole plate 18 above the floor surface when the cleaner head 12 is located on a hard floor surface 70, but when the cleaner head 12 is located on a carpeted floor surface 60 the support members 24 sink into the pile of the carpet to enable the bottom surface of the sole plate 18 to engage the fibres of the carpet. The sole plate 18 is preferably pivotable relative to the housing 16 to allow the sole plate 18 to ride smoothly over the carpeted floor surface 60 during cleaning.
The coupling 14 comprises a conduit 26 supported by a pair of wheels 28, 30. The conduit 26 comprises a forward portion 32 connected to the outlet duct 22, a rearward portion 34 pivotably connected to the forward portion 32 and connectable to a wand, hose or other such duct of a cleaning appliance which comprises dirt and dust separating apparatus and a motor-driven fan unit for drawing dirt-bearing air through the suction opening 20 from the floor surface. A flexible hose 36 is held within and extends between the forward and the rearward portions 32, 34 of the conduit 26.
The cleaner head 12 comprises agitating apparatus for agitating dirt and dust located on the floor surface. In this example the agitating apparatus comprises a rotatable brush bar 40 which is mounted within a brush bar chamber 42 of the housing 16. The brush bar 40 is driven by a motor (not shown) located in a motor housing 44 of the housing 16. The motor is electrically connected to a terminal located in the rearward portion 34 of the conduit 26 for connection with a conformingly profiled terminal located in a duct of the cleaning appliance to enable electrical power to be supplied to the motor.
The brush bar 40 is connected to the motor by a drive mechanism located, at least in part, within a drive mechanism housing 46 so that the drive mechanism is isolated from the air passing through the suction passage. One end of the brush bar 40 is connected to the drive mechanism to enable the brush bar 40 to be driven by the motor, whereas the other end of the brush bar 40 is rotatably supported by an end cap 48 mounted on a side wall of the brush bar chamber 42.
The brush bar 40 comprises an elongate body 50 bearing two different types of bristles for agitating dirt and dust from the floor surface as the brush bar 40 is rotated by the motor. Each of the different types of bristles protrudes from the suction opening 20 in the sole plate 18 as the brush bar 40 is rotated by the motor.
A first agitating means mounted on the body 50 of the brush bar 40 comprises relatively short, preferably relatively stiff, bristles 52. These bristles 52 are preferably formed from nylon. In this embodiment the relatively short bristles 52 are arranged in two angularly spaced, helical rows extending along the body 50. Within each row, the relatively short bristles 52 are arranged in a series of clusters regularly spaced along the row. The length of the relatively short bristles 52 is chosen so that the tips of these bristles do not protrude beneath a plane extending between the lowermost extremities of the support members 24 during rotation of the brush bar 40.
A second agitating means mounted on the body 50 of the brush bar 40 comprises relatively long, preferably relatively soft, bristles 54 which protrude radially outwardly beyond the relatively short bristles 52, as illustrated in Figure 4. For example, during rotation of the brush bar 40 the difference between the diameter D2 of the cylinder swept by the relatively long bristles 54 and the diameter Dl of the cylinder swept by the relatively short bristles 52 is preferably in the range from 1 to 10 mm. In contrast to the relatively short bristles 52, the length of the relatively long bristles 54 is chosen so that these bristles protrude beyond the plane extending between the lowermost extremities of the support members 24 during rotation of the brush bar 40.
In this embodiment the relatively long bristles 54 are connected to the body 50 so as to define four angularly spaced, continuous rows of agitating members extending helically along the body 50. These rows are also angularly spaced from the rows of relatively short bristles 52. Referring also to Figures 2 and 3, adjacent rows of agitating members defined by the relatively long bristles 54 are formed from the respective ends of a row of relatively long bristles 54. Each row of relatively long bristles 54 is partially located between the body 50 and a connecting member 56 connected to the body 50 so that the ends of relatively long bristles 54 protrude outwardly from the body 50. The connecting members 56 are preferably in the form of strips of material arranged helically about the body 50 alternately with the rows of relatively short bristles 52. The connecting members 56 may be mounted on the body 50 by means of screws or other fixing members inserted into apertures 58 formed in the connecting members 56.
Alternatively, the connecting members 56 may be attached to the body 50 using an adhesive. The connecting members 56 are preferably located within helical grooves formed in the body 50.
The relatively long bristles 54 are formed from material having a lower surface resistivity than the material from which the relatively short bristles 52 are formed. The relatively long bristles 54 may be formed from electrically conductive material. The relatively long bristles 54 preferably comprise carbon fibre bristles, but these bristles may be formed alternatively from metallic, graphite or other composite material. The surface resistivity of the relatively long bristles 54 is preferably in the range from 1x105 to lxlO'2 �=/sq. In comparison, the surface resistivity of the relatively short bristles 52 is preferably higher than lx 1012 �=/sq.
With reference to Figure 4, when the cleaner head 12 is located on a carpeted floor surface 60 the support members 24 sink into the pile of the carpet so that the bottom surface of the sole plate 18 engages the fibres of the carpet. As both the relatively short bristles 52 and the relatively long bristles 54 protrude from the suction opening 20 as the brush bar 40 rotates, both the different types of bristles are able to agitate dirt and dust from the floor surface. When an air flow is generated through the suction passage of the cleaner head 12, this dirt and dust becomes entrained within the air flow and is conveyed through the floor tool 10 to the cleaning appliance.
When the cleaner head 12 is moved from the carpeted floor surface 60 on to a hard floor surface 70, as illustrated in Figure 5, the sole plate 18 becomes spaced from the hard floor surface 70. As the tips of the relatively short bristles 52 do not protrude beneath the plane extending between the lowermost extremities of the support members 24, these bristles do not come into contact with the hard floor surface 70, thereby preventing scratching or other marking of the hard floor surface 70 by these bristles.
However, as the relatively long bristles 54 protrude beyond this plane, these bristles engage, and are swept across, the hard floor surface 70 with rotation of the brush bar 40.
Due to the relatively low surface resistivity of the relatively long bristles 54, any static electricity residing on the hard floor surface 70 is discharged upon contact with the relatively long bristles 54, thereby enabling fine dust and powder which would otherwise be attracted to the hard floor surface 70 to be dislodged from the floor surface by these bristles and entrained within the air flow.
The invention is not limited to the detailed description given above. Variations will be apparent to the person skilled in the art.
For example, in the embodiment described above, the cleaner head 12 includes a brush bar 40 that is driven by a motor 6. However, the cleaner head 12 may include alternative means for agitating or otherwise working a surface to be cleaned. By way of example, the brush bar 40 may be driven by an air turbine rather than a motor.
The relatively short bristles 52 may be formed from similar material as the relatively long bristles 54 in order to discharge any static material residing on a carpeted floor surface, and so may also have a surface resistivity in the range from 1x105 to lxlO'2 �=/sq.
The different types of bristles 52, 54 need not be spaced apart. The brush bar 40 may comprise a plurality of rows, clumps or tufts of bristles, with each row, clump or tuft comprising both types of bristles. For example, relatively short bristles 52 may be dispersed within each row of relatively long bristles 54.
The agitating means may take forms other than bristles, such as flexible or rigid strips of material mounted on the body 50, or filaments sewn into a backing material connected to the body 50.
In the event that the floor tool 10 is not to be used on a carpeted surface, the relatively short bristles 52 may be dispensed with so that the brush bar 40 comprises only electrically conductive agitating members. Consequently, the brush bar 40 may comprises solely the continuous rows of electrically conductive surface agitating members defined by the relatively long bristles 54 illustrated in Figures 2 to 5.
Alternatively, the brush bar 40 may comprise a different arrangement of electrically conductive surface agitating members for discharging static electricity residing on a floor surface.
For example, with reference to Figure 6 an alternative brush bar 80 for use in the floor tool 10 comprises a rotatable body 82 having an outer surface comprising an electrically conductive pile 84. In this example, the pile 84 is similar to the raised or fluffy surface of a carpet, rug or cloth, comprising electrically conductive filaments woven on to a fabric carrier member attached to the body 82, for example using an adhesive. The length of the filaments of the pile 84 is preferably in the range from 4 to 10 mm.
These filaments are preferably formed from carbon fibre material, but alternative they may be formed from metallic material or other composite material. Consequently, the surface resistivity of the filaments of the pile 84 is preferably in the range from 1x105 to lx 1012 �=/sq. The fabric carrier member may be in the form of a strip wound on to the body 82 so that the pile 84 is substantially continuous, substantially covering the outer surface of the body 82. Alternatively, the carrier member may be in the form of a cylindrical sleeve into which the body 82 is inserted.
If so desired, clumps of relatively stiff bristles may be dispersed within the pile 84.
Alternatively, a strip of the pile 84 may be wound around one or more helical rows of relatively stiff bristles previously attached to the body 82. These bristles may be similar to the relatively short bristles 52 of the brush bar 40, and so may be arranged so as to not protrude radially outwardly beyond the filaments of the pile 84.
