[0001] This invention relates to a floor cleaning apparatus which is able to carry out cleaning
using one or more of a plurality of selectively different cleaning methods.
[0002] Its well known to provide a floor cleaning apparatus which can provide the user with
a plurality of different cleaning methods which the user can select according to their
needs.
US2010/0287716 discloses one such apparatus which comprises a steam cleaning function and a dry
sweeping function. The apparatus comprises a main power switch which, when actuated,
energises a heating element of a water heater to produce steam. The main power switch
is also connected in series with a further switch, which can be actuated to energise
a motor which drives a floor sweeping brush. The apparatus also comprises an upstanding
elongate handle for guiding the apparatus over the floor surface to be cleaned. A
trigger is provided on the upper end of the handle to energise a pump to dispense
steam onto the surface to be cleaned.
[0003] In use, in order to carry out dry sweeping, the user has to energise the main switch
and the brush motor switch. The user can then selectively actuate the trigger to simultaneously
carry out steam cleaning. Alternatively, the user can carry out just steam cleaning
by actuating the trigger and turning off the brush motor switch.
[0004] A disadvantage of the above-mentioned arrangement is that the apparatus is complicated
and inconvenient to use.
[0005] We have now devised an improved floor cleaning apparatus.
[0006] In accordance with the present invention there is provided a floor cleaning apparatus
comprising means for providing a first cleaning mode, means for providing a second
cleaning mode, a switch operable to select the first and/or second cleaning mode,
an upstanding handle, and a switch disposed adjacent the upper end of the handle which
can be actuated to operate the cleaner in accordance with the selected mode(s).
[0007] In use, the user can select the desired mode or modes of cleaning using the mode
switch. The user is then able to operate the cleaner to provide the selected mode(s)
of cleaning by actuating the switch which is conveniently located on the handle. In
this manner, the user does not have to bend down or look at the cleaner in order to
activate and deactivate any of the selected modes of operation. In particular, the
user does not have to adjust their hand position to de-energise a sweeping brush of
the apparatus, with the result that the brush can be stopped easily in the event that
it becomes snagged or when passing over delicate floor surfaces.
[0008] Preferably the handle switch is connected in series with the mode switch and a pair
of power conductors which feed power to the appliance.
[0009] Preferably said first mode comprises a steam-cleaning mode provided by a steam generator.
Since steam generators can take a certain amount of time to heat up, it is necessary
to provide power to the steam generator at all times, so that steam cleaning may be
provided on demand. Accordingly, a main switch may be provided in series with the
handle switch and the conductors, the main switch being arranged to apply power to
the handle switch and to heating element of the steam generator.
[0010] Preferably the second cleaning mode comprises a dry cleaning mode, such as a sweeping
mode or a vacuum cleaning mode.
[0011] The mode switch preferably comprises first and second configurations for providing
the first and second modes respectively. In an alternative embodiment, the mode switch
may further comprise a third configuration for providing said first and said second
modes simultaneously. In a third embodiment, said mode switch may also actuate said
main switch when at least one of the modes is selected.
[0012] Preferably the mode switch is arranged to connect a pump and/or a motor in series
with the conductors in order to respectively provide said first and second modes of
cleaning.
[0013] An embodiment of the present invention will now be described by way of example only
and with reference to the accompanying drawings, in which:
Figure 1 is a schematic front view of an embodiment of floor cleaning apparatus in
accordance with the present invention;
Figure 2 is a schematic side view of the apparatus of Figure 1; and
Figure 3 is a circuit diagram of the apparatus of Figure 1.
[0014] Referring to Figures 1 and 2 of the drawings, there is shown a floor cleaning apparatus
in accordance with the present invention which is arranged to selectively provide
a steam cleaning function and/or a floor sweeping function. The apparatus comprises
an upright body portion 10 which is pivotally connected at its lower end to a floor-engaging
head 11 via a pivotable neck 12. An elongate handle 13 extends upwardly and rearwardly
from the upper end of the body portion 10 for guiding the apparatus over the floor
surface to be cleaned. The upper end of the handle 13 is provided with a hand-grip
14. A trigger 15 is mounted on the handle 13 adjacent the hand grip 14 in a position
where it is within easy reach of the user's hand whilst holding the hand grip 14.
[0015] The body portion 10 comprises an external housing 23 having a front face on which
a main power switch 16 and a mode switch 17 are provided. The housing 23 encloses
a water tank 18, which can be filled via a filler tube 19 having an opening at the
rear of the housing 23. A tubular outlet duct 40 extends from the water tank 18 via
a pump 20 and a steam generator 21 to a dispensing outlet 24 provided on the underside
of the head portion 11.
[0016] The head 11 comprises a set of wheels 28 on its underside. An elongate brushing member
25 is rotatably mounted transverse the direction of movement of the cleaner, the brushing
member 25 extending through an aperture in the underside of the cleaner so that it
engages the floor surface to be cleaned. A motor 27 drives the brush 25 via a belt
29. Any dirt and dust on the floor surface is swept by the rotating brush 25 into
a removable collection chamber 26 mounted inside the head 11 behind the brush 25.
One or more cleaning pads (not shown) of felt, micro-fibre or other material may also
be mounted on the underside of the head 11. An elongate power cable 22 extends from
the body 10 of the cleaner for collecting it to the mains supply.
[0017] Referring to Figure 3 of the drawings, the live conductor L of the cable 22 is connected
via the main switch 16 and a thermostat 30 to one side of a heating element 31 of
the steam generator 21. The other side of the heating element 31 is connected to the
neutral conductor N of the cable 22 via a thermal fuse 32. The main switch 16 is also
connected to a switch 33 which is operated by the trigger 15 on the handle 13. The
other side of the switch 33 is connected to an inlet terminal 34 of the mode switch
17. The mode switch 17 further comprises a pair of outlet terminals 35, 36 and a displaceable
contact member 37 for selectively connecting the inlet terminal 34 to the outlet terminal
35 and/or the outlet terminal 36.
[0018] An externally operable actuator is provided for moving the contact member 37.
[0019] The outlet terminal 35 is connected to one side of a motor of the pump 20, the other
side of the motor being connected to the neutral conductor N of the supply cable 22.
The outlet terminal 36 is connected to one side of the brush motor 27, the other side
of the brush motor 27 being connected to the neutral conductor N of the supply cable
22.
[0020] In use, the user firstly has to actuate the main switch 16, which then energises
the heating element 31 of the steam generator 21, so that the steam generator 21 is
always at the required temperature and ready for use. The user is able to select the
desired mode of cleaning by turning the mode switch 17 to the appropriate position
to provide the steam cleaning mode and/or the dry sweeping mode. It will be appreciated
that the selected mode(s) will not be provided until the user grasps the handle 13
and operates the trigger 15 to actuate the switch 33 which is connected in series
with the mode switch 34. In this manner, the user is able to simply activate and de-activate
the cleaning mode by operating the trigger.
[0021] In an alternative embodiment, the motor 27 may be the motor of a fan unit of a vacuum
cleaner. In a further embodiment, the mode switch 17 may be configured so that only
one mode of cleaning or the other can be provided.

in construction and allows the user to activate and de-activate the cleaning functions
without having to move their hand from the hand grip.
