Description
FIELD OF THE INVENTION
[0001] This invention relates to cleaning equipment in which
cleaning liquid is taken from a container, for example, a bucket,
and returned thereto after it has been used for dirt removal. It is
of particular, but by no means exclusive, application to a cleaning
bucket for use with a cleaning element or device, such as a floor
mop, cleaning cloth or chamois leather which is repeatedly wrung
out into the bucket.
BACKGROUND OF THE INVENTION
[0002] A problem with such cleaning equipment is that dirt
deposited out from the liquid collects at the bottom of the
container and that disturbance of the liquid, as when rinsing out a
mop for example, washes the collected dirt back into the main body
of the liquid. In addition, a cleaning element such as a mop can
pick up the collected dirt directly. Because of this the container
is often emptied and cleaned out before the cleaning additives in
the liquid are actually exhausted.
[0003] A small container is defined herein as having an interior
volume comparable to that of a typical household pail or bucket.
Typical interior volumes range between 11 liters and 20 liters.
OBJECTS OF THE INVENTION
[0004] The objects of the present invention are: to provide a
multi-compartment cleaning bucket by which a mop used in the bucket
is not exposed to dirty water; to provide such a cleaning bucket
continuing a filtering element for retaining soil; to provide such
a bucket substantially preventing washing back of soiled water into
a rinsed mop; and to provide such a cleaning bucket which is well
suited for the intended purpose.
SUMMARY OF THE INVENTION
[0005] According to the present invention, there is provided
cleaning equipment comprising a container for cleaning liquid, a
wringer mounted on or in the container, a partition element
dividing the container into a first compartment which, in use,
receives liquid wrung out in the wringer and a second compartment
which, in use, receives cleaning liquid and a dirt receiving
element for receiving dirt settling from the cleaning liquid in use
contained in the second compartment
[0006] This arrangement is advantageous, since it prevents or
limits settled dirt from being drawn or re-circulated back into the
cleaning liquid. This thus enables dirt-settling characteristics,
commonly only associated with large containers, to be imparted to
small containers.
[0007] Preferably, the partition element has a part defining the
base of the second compartment. This part is preferably apertured
and the dirt receiving element is preferably located below the said
apertured part of the partition element.
[0008] Advantageously, the first and second compartments
communicate with one another via the dirt receiving element.
[0009] Conveniently, the partition element is removable from the
container to facilitate cleaning of the cannister and dirt
receiving element.
[0010] The dirt receiving element may comprise a mat or pad of
superposed mesh layers or may be a non-women unitary mesh
comprising a "jumble" of interlocking or bonded fibers.
BRIEF DESCRIPTION OF THE DRAWINGS
[0011] The invention will now be more particularly described, by
way of example, with reference to the accompanying drawings, in
which:
[0012] FIG. 1 shows a top plan view of one embodiment of cleaning
equipment, according to the invention;
[0013] FIG. 2 shows a vertical cross-section of the cleaning
equipment, taken along line A-A in FIG. 1;
[0014] FIG. 3 is a prospective view of the cleaning equipment of
FIG. 1; and
[0015] FIG. 4 is a wringer-end view of the cleaning equipment
showing part of the wringer in phantom lines.
DESCRIPTION OF THE PREFERRED AND ALTERNATE EMBODIMENTS
[0016] Referring to the drawings, the cleaning equipment shown
therein is typically for domestic use and comprises a small
container of the type hereinbefore defined and which is in the form
of a bucket 1, a basket-like wringer 2 including a support flange 8
removably mounted on the upper lip of the bucket 1 so as to cover
only a part of the upper end of the bucket 1, and a partition
element 3 which divides the bucket 1 into a first compartment 4
which receives liquid wrung out in the wringer 2 and a second
compartment 5 which receives liquid, e.g. clean water and a
flocculent chemical.
[0017] The partition element 3 curves gently away from the wringer
2 in a downwards direction and has a flat lower part 3a which
defines the base of the second compartment 5.
[0018] The part 3a of the partition element 3 is provided with a
plurality of apertures and a dirt receiving element 6 is located
below the part 3a of the partition element 3. The dirt receiving
element 6 may be secured to the underside of the part 3a of the
partition element, typically by adhesive.
[0019] The element 6 is a three dimensional fibrous mesh structure
(or reticulated foam structure) and may comprise a mat or pad of
superposed mesh layers or may be a non-woven unitary mesh
containing a "jumble" of interlocking or bonded fibers.
[0020] The first and second compartments 4 and 5, respectively,
communicate with one another via the element 6 and the apertures in
the part 3a of the partition element 3. Thus, the water level in
each of the two compartments 4 and 5 will maintain the same level
and the water level in the first compartment 4 will not exceed that
in the compartment 5 as cleaning liquid is wrung out in the wringer
2.
[0021] The flocculent chemical draws small particles out of the
suspension and these particles, together with heavier dirt
particles settle into the filter.
[0022] The form of the element 6 is such that disturbances in the
liquid cannot wash back out into the body of the liquid, to any
material extent, dirt particles which are deposited from the liquid
and which settle into the inter-fiber spaces of the element 6. In
fact, the act of rinsing the cleaning element in the compartment 5
creates a bellows effect producing turbulence to drive the dirt
particles into the compartment 4. There is little turbulence in
compartment 4 so there is little or no flow back from compartment 4
to compartment 5.
[0023] The partition element 3 is removable from within the bucket
1 to facilitate cleaning of the bucket and fits behind a depending
flange 7 on the wringer support flange 8. Movement of the partition
element 3 towards the first compartment 4 is restrained.
[0024] In use, a mop or other cleaning implement is rinsed out in
the cleaning liquid in the second compartment 5 and is then wrung
out in the wringer 2. The mop or other cleaning implement is then
used to clean, for example, a work surface and then rinsed again in
the cleaning liquid in the second compartment.
[0025] Dirt removed from the cleaning implement during a rinsing
operation is trapped in the dirt receiving element 6. This avoids
the need to change the cleaning liquid too frequently. As such, the
small container assumes the characteristic of a much larger
container wherein the dirt dispensed into the cleaning liquid tends
to settle and remain at or adjacent to the bottom of the container.
Additionally, and again similarly to a larger container, there is
then less likelihood that the settled dirt is agitated leading to
re-circulation back into the majority of the cleaning liquid.
[0026] Ideally, the dirt receiving element is a re-usable unit
which can be replaced in the container after removal therefrom and
washing out of the collected dirt.
[0027] Also, the bucket may be of transparent plastics material for
observation of the water condition.
[0028] The invention has particular applicability to a small
container as hereinbefore defined. However, the container can be of
any suitable size, large or small.
[0029] Although the wringer is a manual-type basket wringer,
whereby the squeezing action is solely due to the mop user applying
a downwards force, the wringer could be any suitable type of
wringer, such as a mechanical wringer which may be, for example,
lever operated. A suitable wringer of this type is known from
GB2340738.
[0030] The above embodiment is given by way of example only and
various modifications will be apparent to persons skilled in the
art without departing from the scope of the invention as defined by
the appended claims. For example, the wringer could be mounted on a
ledge in the bucket rather than be mounted on the upper lip of the
bucket.
