Description

1 2411107 Cleaning Device This invention relates to a cleaning device, a

cleaning section of a cleaning device, a method of driving a cleaning section of the cleaning device and a method of cleaning.

A number of automatic cleaning devices are known that are used to clean a floor by automatically moving around that floor as a cleaning operation is performed. The prior art devices clean by means of a pad secured to the underside of the device, which pad engages a floor to be cleaned as the device moves across that floor and thereby picks up dirt as it moves.

Disadvantages arise with this type of cleaning device in that the cleaning pad rapidly becomes soiled as the device moves across the floor.

It is an object of the present invention to address the above mentioned disadvantage.

According to a first aspect of the invention, a cleaning device incorporates a cleaning section and a drive section, wherein the drive section is operable to drive the cleaning device over a surface to be cleaned, and wherein the cleaning section is operable to drive a cleaning element of the cleaning section relative to a body of the cleaning device and to drive the cleaning element to a surface engaging position for a cleaning operation.

The cleaning section may be operable to move the cleaning element from a supply section to a take-up section via the surface engaging position. The cleaning element is preferably in contact with the surface to be cleaned when in the surface engaging position.

The cleaning section may incorporate at least one pressure element operable to urge the cleaning element towards the surface to be cleaned, preferably whilst in the surface engaging position. The supply and/or take-up sections may be pressure elements. One or more guide elements, which may be rollers, may be pressure elements. First and second guide elements may be pressure elements.

Alternatively, a first guide element and one of the supply IS and take-up sections may be pressure elements. The or each pressure element is preferably biased downwards.

The supply section may be located to a rear of the take-up section. The cleaning section may be operable to move the cleaning element substantially in a direction of forward travel of the cleaning device. The take-up section may be located to a rear of the supply section. The cleaning section may be operable to move the cleaning element in a direction substantially opposite to a direction of forward travel of the cleaning device.

The cleaning element, when in the surface engaging position, preferably extends across a front edge of a lower face of the cleaning device. A width of the cleaning element preferably extends substantially perpendicularly to a direction of forward travel of the cleaning device. The cleaning element may extend at an angle to the front edge.

A section of the cleaning element in the surface engaging position preferably has a width across a direction of forward travel that is at least about two times, preferably at least about three times, wider than a length in the direction of forward travel.

The take-up section may be powered, preferably by a motor, which may be a motor also adapted to power the drive section. The take-up section is preferably adapted to be rotated at a much lower speed than the drive section, which may be a factor of approximately at least 3000 times slower.

The take-up section may be operable to be actuated manually by a user, to change a section of the cleaning element that is in the surface engaging position. The take-up section may be controlled by the cleaning device, which control may be effected by a timer.

The cleaning section may incorporate a drum carrying the cleaning element, which drum may be powered or may be manually operated. The cleaning element may be replaceable by a user.

The cleaning section may include a cleaning fluid supply section, which is preferably operable to supply fluid to a part of the cleaning element prior to that part of the cleaning element moving to the surface engaging position.

The cleaning fluid supply section may be switchable to prevent a supply of fluid to the cleaning element.

The supply section may contain a cleaning element that has been pretreated with a cleaning fluid. The supply section may be sealable by a user, to allow the supply section to retain the cleaning fluid between uses.

The cleaning element may be made of an absorbent material, to better allow take-up of cleaning fluid and to better allow removal of material from a surface to be cleaned.

An end section of the cleaning element may be non- absorbent. The non-absorbent end section may be adapted to prevent cleaning fluid being deposited on a surface after a cleaning cycle when the cleaning device is at rest.

The invention extends to a cleaning section for a cleaning device as described in the first aspect.

According to a second aspect of the invention a method of driving a cleaning section of a cleaning device comprises feeding a cleaning element of the cleaning section from a supply section to a take-up section past a position at which the cleaning element is located to engage a surface to be cleaned.

The cleaning element is preferably biased towards the surface to be cleaned, preferably downwards, preferably at front and rear edges of the surface engaging position.

The take-up section or the supply section may be biased towards the surface to be cleaned. At least one subsidiary element may hold the cleaning element in contact with the surface.

The take-up section may pull the cleaning element in a direction of forward travel of the cleaning device.

The method may include feeding the cleaning element to the take-up section until the cleaning element is clear of the supply section, preferably being stored on the take-up section.

The method may include feeding the cleaning element to the take-up section until a substantially non-absorbent section of the cleaning element is in the surface engaging position.

According to a third aspect of the invention there is provided a cleaning element for a cleaning section of the second aspect or for a cleaning device of the first aspect.

The cleaning element may be located in a supply section, which may be operable to be exposed for use by a user or closed for use by a user.

According to a fourth aspect of the invention, a cleaning element for a cleaning device has a width substantially across a direction of travel of the cleaning device that is at least two times a length of the cleaning element substantially in a direction of travel of the cleaning device.

Preferably, the width is at least about three times the length.

The cleaning element may be an exposed portion of a larger cleaning member, which may be mounted on a roll.

All of the features described above may be combined with any of the above aspects in any combination.

For a better understanding of the invention, and to show how embodiments of the same may be carried into effect, reference will now be made, by way of example, to the accompanying diagrammatic drawings in which: Figure 1 is a schematic cross-sectional side view of a cleaning device; Figure 2 is a schematic view from below of the cleaning device; Figure 3 is a schematic partial side view of a first arrangement of cleaning section of the cleaning device; Figure 4 is a schematic partial side view of a second arrangementof the cleaning section; Figure 5 is a schematic cross-sectional side view of an alternative arrangement of cleaning section of the cleaning device; and Figure 6 is a schematic crosssectional side view of a further alternative arrangement of cleaning section.

As shown in Figures 1 and 2, a cleaning device 10 comprises a body 12, drive wheel 14, subsidiary wheels 16 and a cleaning section 18 consisting of a cleaning sheet that is moved in the direction of the arrow labelled A in Figure 1 from a supply reel 22 to a take-up reel 24 via a roller 26. In use, the cleaning device 10 is driven by the drive wheel 14 around a floor or surface to be cleaned, during which the cleaning sheet 20 is passed from the supply reel 22 to the take up reel 24. The section of cleaning sheet 20 that is located between the roller 26 and the take-up reel 24 contacts the surface being cleaned and thereby removes dirt from that surface.

In more detail, the cleaning device 10 is constructed and operated as follows. The supply reel 22 is biased by a spring to turn anti-clockwise as shown in Figure 1 in order to maintain tension on the cleaning sheet 20 as it is pulled towards the take-up reel 24. The supply reel 22, although biased to turn anti-clockwise, is able to turn clockwise in order to allow the cleaning sheet 20 to be taken from the supply reel 22. The roller 26 is weighted downwards to ensure that the cleaning sheet 20 passing over the roller 26 is forced towards the surface being cleaned. The weighting may be made by means of a spring mounting. The roller 26 may be mounted for rotation, or may be a low friction material, such as nylon, which allows the cleaning sheet 20 to move around the roller 26 without the need for rotation thereof.

The take-up reel 24 is also spring mounted to urge it towards the surface being cleaned. It is particularly necessary that the take-up reel 24 is urged towards the floor to be cleaned, because the amount of cleaning sheet on the reel will increase as a cleaning operation is produced. Thus, the axis of the take-up reel 24 will need to move away from the floor surface as more cleaning sheet is wound onto the take-up reel 24.

The arrangement described above is shown schematically in Figure 4. In this arrangement the direction of travel is shown by the arrow C. It has been found to be advantageous to have the cleaning sheet 20 wound in the direction of travel, because most dirt is removed from a surface being cleaned by a leading edge of the cleaning sheet 20. Thus, in the arrangement shown in Figures 1, 2 and 4, the most soiled part of the cleaning sheet 20 is immediately lifted from the surface being cleaned to prevent that material being re-deposited on the surface.

IS Also, the provision of the roller 26, being a second roller (after the take-up reel 24) biased towards the surface being cleaned, has the advantage that dirt not picked up by the cleaning sheet 20 as it is wound onto the take-up reel 24 at the point marked A in Figure 4 can be picked up at the arrow marked B in Figure 4 by the cleaning sheet 20 that is passing over the roller 26. By having two lines of pressure exerted, by the take -up reel 24 and the roller 26, advantages are found over a planar pad that would be forced towards the surface to be cleaned in the prior art devices. The advantage is that less drag is found in the system of the present invention over a planar pad. Less drag results in a smaller power requirement for the cleaning device, which is battery powered. Consequently a smaller battery may be used or a longer cleaning cycle may be obtained for a given battery size.

It has been found that the provision of a cleaning sheet engaging a surface to be cleaned between two rollers, i.e. in this situation, between the roller 26 and the take-up reel 24 advantageously provides a cleaning surface that is wide across the direction of travel and that is relatively narrow between leading and trailing edges, provided by the take-up reel 24 and roller 26 respectively. The advantage derived is that the drag of the cleaning sheet 20 where it engages the surface to be cleaned is reduced compared to a pad that is circular or deeper in the direction of travel, or approaching a square. The embodiment described herein has a thin rectangle or strip shape. Thus, the provision of a section of cleaning sheet 20 presented to the floor that it is at least approximately twice as long across the direction of travel as it is wide is advantageous. More preferably, the exposed part.of the sheet 20 may be at least about three times longer than it is wide, for example it may measure approximately 250 mm by 80 mm.

Rather than being approximately perpendicular to the direction of forward motion, when considered in plan view, the exposed cleaning sheet 20, and so the rollers 22, 24 and 26 may be at an angle, such as about 45 to the direction of forward motion.

The length of the cleaning sheet 20 provided may be determined by the size of a surface, such as a floor of a room, that is intended to be cleaned by the cleaning device 10. The length of the cleaning sheet 20 may be approximately one metre. Alternatively, much shorter cleaning sheets 20 may be provided that can be replaced during a cleaning operation.

The drive wheel 14 and the take-up reel 24 may both be driven by the same motor (not shown). A worm drive or the like may be used to reduce a rotation speed of the drive motor to approximately one to two millimetres per minute, S from a speed of the drive motor of approximately 100 to 300 mm per second or an approximate angular speed of 45 per second.

The cleaning sheet 20 may be a dry cleaning sheet, or alternatively may be pre-wetted with a cleaning liquid, such as a detergent, sanitising solution, sterilising solution, water, or other cleaning liquid. A liquid supply section 21 (shown schematically) may be used to apply a cleaning fluid, which may be a gel, such as a detergent, to the cleaning sheet 20 before it passes the roller 26. The cleaning fluid may alternatively be sprayed or dripped just in front of the cleaning sheet 20, where it engages the surface. The cleaning sheet 20 may be pre-wetted on its supply reel 24 and may have additional cleaning fluid sprayed ahead of it, as mentioned above. The above would allow approximately 500ml of cleaning fluid to be used by a combination of pre-wetting and also spraying from the liquid supply section 21. Provision may be made to turn the liquid supply on or off to provide the option of a dry mode of cleaning or a wet mode of cleaning. It is intended that in a wet mode of cleaning the cleaning fluid or sanitising solution would leave the surface being cleaned wet for at least 30 seconds before it dries. This allows for the advantageous use of sanitizing fluids to kill unwanted organisms, such as bacteria etc. The cleaning sheet 20 may be arranged so that the cleaning device 10 moves around the surface to be cleaned until the cleaning sheet is exhausted and is completely wound onto the take-up reel 24. Such a feature has the advantageous effect of stopping the cleaning device 10 so that the cleaning sheet 20 is not left in contact with the surface being cleaned at an end of a cleaning procedure. If the cleaning sheet 20 in a wet state was left on the surface, then disadvantageous damaging of the surface being cleaned or disadvantageous wetting may have resulted.

Alternatively, in order to achieve the same effect, an end section of the cleaning sheet 20 may be plastic or the like so that it is not absorbent and does not apply the cleaning fluid to the surface when the roll is at an end.

Thus, although the cleaning sheet 20 would not have wound completely off the supply reel 22, no absorbent material will be left in contact with the surface being cleaned, because the latter section is a non-absorbent sheet.

In order to avoid leaving a wet cleaning sheet 20 on the surface being cleaned, the reels 22/24 and the roller 26 may be arranged to retract from the surface after a cleaning operation and so lift the cleaning sheet 20 from the surface. Alternatively, a shield (not shown) may slide across to cover the cleaning sheet 20 and prevent undesired wetting of the surface.

Figure 3 shows an alternative arrangement of the cleaning section 18. The view is very similar to that as shown in Figure 4 except that the positions of the supply reel 22 and the take-up reel 24 are reversed. Thus, with the direction of travel to the left as marked by the arrow C in Figure 3, the cleaning sheet 20 is pulled with the direction of travel by the take-up reel 24, which is located to the rear of the supply reel 22. This arrangement has the advantage of creating less friction between the cleaning sheet 20 and the surface being cleaned, because this direction of travel of the cleaning sheet results in a lesser relative speed of movement between the cleaning sheet 20 and the surface being cleaned. However, this arrangement results in the leading edge of the cleaning sheet 20 at the point marked by the arrow A in Figure 3 being the part that collects most dirt, but that part is then moved towards the roller 26 at the arrow marked B. Thus, dirt that has been picked up by the cleaning sheet 20 at the point marked by the arrow A could potentially be re-deposited as it travels towards the point marked by arrow B. The arrangement shown in Figure 3 requires less power however. In Figure 3 the same reference numerals are used for the parts that are in common with the device described above in relation to Figures 1, 2 and 4.

Figure 5 shows a further possibility for arrangement of the cleaning section 18 of the cleaning device 10. The arrangement is similar to that as shown in Figure 1 and like reference numerals are used for like parts. The arrangement in Figure 5 differs by the provision of a further roller 27 forward of the roller 26. This arrangement allows the supply reel 22 and the take-up reel 24 to be housed within the body 12 of the cleaning device 10. The roller 27 may be of the same material as that of the roller 26 as described above. Both of the rollers 26 and 27 may be journalled to allow rotation thereof, or may be low friction fixed rollers which allow the cleaning sheet 20 to move smoothly across them. The latter arrangement is more simple mechanically, requiring only the rollers 26 and 27 to be pushed against the surface to be cleaned by a suitable weighting of the rollers or a bias of the rollers, as opposed to the greater amount of travel that is required for the take-up reel 24 described in relation to Figures 1, 2 and 4.

Figure 6 shows a further alternative arrangement for the cleaning section 18 of the cleaning device 10. Like numerals for the common parts with previous embodiments have been used in Figure 6. This embodiment uses a single roller 28 having a cleaning sheet 30 located on an outer periphery thereof. This embodiment is considerably simplified and uses a single rotation of the roller 28 to clean the surface over which the cleaning device is passing. Thus, with one rotation the roller 28 is spent and would need to be replaced or cleaned. The cleaning sheet 20 may be a replaceable element to be wrapped around the roller 28 to minimise the number of parts to be replaced. The cleaning sheet 20 may be placed on the roller 28 in a wet form to allow the cleaning device 10 to clean using a sanitising solution as described above. The roller 28 is driven by a feed from a drive motor (not shown) which drives the cleaning device 10 as described above. The embodiment shown in Figure 6 has the advantage of having a considerably simpler cleaning section 18 which can be more simply manufactured and replaced than those described above in relation to previous embodiments.

In a variation on the embodiment shown in Figure 6, the roller 28 may be only a partial cylinder, possibly semi- circular in cross-section or having only an arc of a circle for a curved face. In use, the roller may be rocked forwards and backwards about its centre of curvature, rather than being rotated, so as it is rocked a different leading edge is presented to the surface. The cleaning sheet may be in the form of a sleeve passed over the semi-circular or arc shaped roller.

All of the arrangements shown in Figures 1 to 6 may be varied so that there is manual changing of the exposed section of cleaning sheet 20, for example by actuation of a lever to move the sheet 20 from supply reel 22 to take- up reel 24. Thus, instead of driving the cleaning sheet 20 between reels, or as shown in Figure 6, automatically rotating the roller 28, a user may expose a clean section of cleaning sheet 20 when desired.

All of the embodiments described above relate to a cleaning device that is driven around a surface to be cleaned, such as a floor, in either a random way or in a controlled way.
