Abstract
This invention relates to a multi-purpose position sensitive floor cleaning device having two separate and distinct selective modes of operation whereby 180° longitudinal rotation of the floor cleaning device selectively activates one of the two separate and distinct selective modes of operation. The two separate and distinct selective modes of operation are, for example, a scrubbing mode for scrubbing an associated floor and a suctioning mode for suctioning associated liquid from the associated floor.
Description
BACKGROUND OF THE INVENTION
1. Field of Invention
This invention pertains to a floor-cleaning device. More specifically, this invention pertains to a multi-purpose position sensitive floor-cleaning device having a gravity switch that selectively activates at least a first motor to provide power to at least a first implement when the cleaner is rotated or flipped about its longitudinal axis.
2. Description of the Related Art
It is known in the prior art to provide floor-cleaning devices operated by a switch containing two tubes of mercury, also known as gravity switches. For example, gravity switches have been used to create a “dead man” condition in floor cleaning devices. U.S. Pat. No. 2,138,279 ('279 patent) (expired) discloses such a “dead man” switch. The '279 patent relates to a control switch that includes two tubes of mercury, which are mounted in a head of a floor care appliance. Each tube includes two spaced contacts, which are interposed in an electric circuit. Rotating handgrips that tilt the mercury tubes to complete the circuit operates the machine. A spring is provided to create the “dead man” condition. When the handgrips are released, the spring returns the mercury tubes to the “off” position. Thus, a gravity switch on a floor care appliance for use as a “dead man” switch is known in the art. However, the '279 patent does not disclose the use of a gravity switch to alternate between two or more modes of operation such as scrubbing and suction modes.
It is also known to use a level-sensitive switch to turn off a motor on a carpet-cleaning machine when the handle of the device is tilted. In U.S. Pat. No. 4,146,944 ('944 patent) (expired), a carpet cleaning machine having a handle, a cleaning head with a brush, a brush motor, a solution supply tank, a rinsing reservoir, a waste tank, a vacuum head and a vacuum pump is disclosed. A level sensitive switch is provided in the cleaning head to turn off the brush motor when the handle is tilted to raise the brush and lower the vacuum head. Further, the '944 patent discloses that the same level sensitive switch can be used to turn the vacuum motor on when the handle is tilted. Thus, the level sensitive switch disclosed in this patent selectively activates a first motor, namely, the brush motor, when the handle is tilted to lower the brush and raise the vacuum head. In addition, the gravity switch selectively activates a second motor, namely, the vacuum motor, when the handle is tilted to raise the brush and lower the vacuum head. However, the patent does not disclose rotation of the entire unit to selectively activate a mode of operation.
Another example of use of the use of gravity to influence a device is found in U.S. Pat. No. 3,676,890 ('890 patent) (expired). The '890 patent relates to a suction cleaner having a detent mechanism pivotally mounted by a pin on the handle control lever. The detent includes an arcuate surface at one end; a portion on the other side of the pivot pin is weighted so that it is influenced by gravity to rotate the detent when the cleaner is up-ended onto a surface. The detent engages a roller to lock the cleaner in the upright position and prevent actuation of a switch actuator.
The present invention is an improved multi-purpose position sensitive floor cleaning device having two separate and distinct selective modes of operation whereby 180° rotation of the multi-purpose position sensitive floor cleaning device selectively activates at least one of the two separate and distinct selective modes of operation.
SUMMARY OF THE INVENTION
It is an object of the present invention to provide a multi-purpose position sensitive floor-cleaning device having two separate and distinct selective modes of operation whereby 180° rotation of the floor-cleaning device selectively activates one of the two separate and distinct selective modes of operation. The two separate and distinct selective modes of operation are, for example, a scrubbing mode for scrubbing an associated floor and a suctioning mode for suctioning associated liquid from the associated floor.
The activation of the one of the two separate and distinct selective modes of operation can be accomplished, in its preferred embodiment, by a gravity switch. The gravity switch activates one of the two separate and distinct selective modes of operation due to the gravitational force acting upon the gravity switch.
Another object of the present invention is the multi-purpose position sensitive floor cleaning device to have a longitudinal axis with a cleaning head at a first end of the longitudinal axis and a handle at a second end of the longitudinal axis, a motor being located between the first and second ends for operating the cleaning head, wherein the improvement comprises a switch for activating and deactivating the motor, the switch activates the motor when the floor care device is rotated about the longitudinal axis and when the cleaning head is placed in contact with the floor surface, and the switch deactivating the motor when the floor care device is rotated about the longitudinal axis to place the cleaning head in a non-contact position with the floor surface.
Another object of the improved multi-purpose position sensitive floor cleaning device is to rotate the floor care device 180°, thus placing the cleaning head in a non-contact position with the floor surface.
Another object of the present invention disclosed herein is an improved multi-purpose position sensitive floor-cleaning device for cleaning a bare floor. The improved floor cleaning device has a longitudinal axis, a handle, a housing, the housing having first and second ends, the first end of the housing being attached to the handle, at least two separate and distinct modes of operation, the at least two separate and distinct modes of operation, for example, being a cleaning mode and a suction mode, at least one implement operatively attached to the second end of the housing and having an axis parallel to a plane of a floor, the axis being perpendicular to the longitudinal axis of the improved floor cleaning device, the at least one implement operatively attached to the second end of the housing comprises two implements, the two implements being a power-driven brush and a pump communicating with a nozzle for dispensing a cleaner, the power-driven brush and the pump being located substantially opposite one another, at least one motor operatively connected to the at least one implement, a means for supplying power to the improved floor cleaning device, a means for activating and deactivating the means for supplying power, a means for activating and deactivating the at least one motor, the means for activating and deactivating the means for supplying power being a first switch, the means for activating and deactivating the at least one motor activating the motor by rotating the improved cleaning device 180° about its longitudinal axis such that the at least one implement is in contact with a surface of a floor, the means for activating and deactivating the at least one motor selectively deactivating the at least one motor when the cleaning device is rotated about the longitudinal axis such that the at least one implement is not in contact with the surface of the floor, the means for activating and deactivating the at least one motor being a gravity switch connected to the second motor and, wherein the floor cleaning device is a bare floor cleaning device.
These and other objects of the present invention are achieved by the present invention wherein there is provided a floor cleaning device comprised of a motor housing having first and second ends, a handle attached to the first end of the motor housing, a cleaning housing having first and second ends, wherein the first end of the cleaning housing is attached to the second end of the motor housing, a nozzle attached to the second end of the cleaning housing, a cleaning solution delivery system positioned within the cleaning housing for dispensing unused cleaning solution onto a floor surface and a recovery tank positioned within the cleaning housing for holding dirty cleaning solution. The device further comprises a means for selectively providing power to the suction motor. The means for supplying power is positioned within the motor housing and includes a master switch, a pump, a suction motor for providing power to the pump, a power means for providing an electrical current to the suction motor and a gravity switch operatively connected to the power means and the suction motor. The device further comprises a power driven brush system for selectively providing power to the brush motor. The power driven brush system includes a power driven brush operatively attached to the nozzle and a power driven motor operatively connected to the gravity switch. When the cleaning device is rotated about its longitudinal axis such that the nozzle faces the floor surface, the gravity switch turns off the brush motor and simultaneously turns on the suction motor. In addition, when the cleaning device is rotated about its longitudinal axis such that the power driven brush faces the floor surface, the gravity switch turns off the suction motor and simultaneously turns on the brush motor.
Another object of the present invention is to provide a method of cleaning a floor surface with a floor cleaning device having at least two modes of operation, at least one means for supplying power, at least one means for activating/deactivating the floor cleaning device, the modes of operation being located opposite one another on the floor cleaning device, wherein the method is the steps of placing the floor cleaning device in a first position contacting the floor, rotating the entire cleaning device a first time, the first rotation of the device is preferably a 180° rotation, to activate the means for supplying power to the floor cleaning device, and rotating the cleaning device a second time to deactivate the means for supplying power to the floor cleaning device. An additional step includes the method wherein the floor cleaning device further has first and second implements mounted opposite one another on the floor cleaning device and selectively contact the floor, and wherein the step of rotating the device a first time results in either the first or the second implement contacting the surface of the floor.
Still other benefits and advantages of the invention will become apparent to those skilled in the art to which it pertains upon a reading and understanding of the following detailed specification.

DETAILED DESCRIPTION OF THE INVENTION
Referring now to the drawings wherein the showings are for purposes of illustrating preferred embodiment(s) of the invention only and not for purposes of limiting the same,
FIGS. 1-3
show a preferred embodiment of the invention.
FIGS. 4-6
show a second preferred embodiment of the invention.
With reference to
FIG. 1
, a cleaning device
10
has a first implement
12
, a removable motor housing
14
having first and second ends
16
,
18
, a handle
20
that is connected to the first end of the motor housing
16
and that extends upwardly therefrom, a cleaning housing
22
having first and second ends
24
,
26
, a second implement
28
having a preferred embodiment squeegee
30
connected to the second end
26
of the cleaning housing
22
, and wherein the first implement
12
is mounted approximately opposite the nozzle
28
. In the preferred embodiment, the first implement
12
is shown as a stationary brush (also referenced as
12
) and the second implement
28
is a nozzle (also referenced as
28
). The second end
18
of the motor housing
14
is removably attached to the first end
24
of the cleaning housing
22
to facilitate the emptying and cleaning of a recovery tank
84
, which is located within the cleaning housing
22
, as will be explained in further detail below. In the preferred embodiment, the removable motor housing
14
has a substantially u-shaped configuration and can be assembled/disassembled to the cleaning device
10
by known means in the art.
With continuing reference to
FIG. 1
, in the preferred embodiment, the squeegee
30
facilitates the nozzle
28
in the removal of dirty cleaning solution from the floor surface
34
. However, the nozzle
28
will adequately remove the dirty cleaning solution from the floor surface
34
without the assistance of the squeegee
30
.
With reference to
FIG. 2
, the first end
24
of the cleaning housing
22
contains a cleaning solution delivery system
32
. The delivery system
32
dispenses a cleaning solution
33
onto the floor surface
34
for later scrubbing by a means for scrubbing the associated floor, identified in the preferred embodiment as the stationary brush
12
. The cleaning solution
33
used in the present invention may be any known cleaning solution or combination of solutions, such as water with a detergent additive.
With continuing reference to
FIG. 2
, the cleaning solution delivery system
32
includes a cleaning solution delivery tank
36
having first and second chambers
38
,
40
, a means
51
for releasing the unused cleaning solution
33
and a cleaning solution delivery tube
56
. The first chamber
38
of the delivery tank
36
sits atop the second chamber
40
and a separator wall
42
separates the two chambers
38
,
40
. The first chamber
38
holds the unused cleaning solution
33
and selectively releases it into the second chamber
40
, which in turn releases the solution onto the floor surface
34
via the solution delivery tube
56
, as will be explained in further detail below. The first chamber
38
has an aperture
44
for receiving the unused cleaning solution
33
. The aperture
44
in the first chamber
38
is aligned with an aperture
46
in the cleaning housing
22
and opens thereto to facilitate filling of the first chamber
38
with the unused cleaning solution. The aperture
46
on the cleaning housing
22
is provided with a threaded dispensing cap
48
that can be removed to allow a user to fill the first chamber
38
with solution.
With continuing reference to
FIG. 2
, the means
51
for selective release of unused cleaning solution
33
from the first chamber
38
to the second chamber
40
is accomplished, in the preferred embodiment, by a plunger
52
. The plunger
52
is received within an aperture
50
located on the separator wall
42
. The plunger
52
also abuts the bottom portion
97
of a control rod
95
which is connected at its upper portion
99
to a means for releasing the liquid
54
(shown in
FIG. 1
) positioned on the handle
20
of the cleaning device
10
which controls the dispensing of the unused cleaning solution
33
. The means for releasing liquid
54
selectively moves the control rod
95
to move the plunger
52
from a closed position to an open position and vice versa.
FIG. 2
shows the plunger
52
in its open position.
FIG. 3
shows the plunger
52
in its closed position. With reference to
FIG. 3
, the plunger
52
seals the aperture on the separator wall
42
and prevents the unused cleaning solution
33
from being released into the second chamber
40
. However, engagement of the means for releasing liquid
54
selectively moves the plunger
52
in an upwards direction to its second position, as shown in FIG.
2
. With reference to
FIG. 2
, when the plunger
52
is in its open position, the seal surrounding the aperture
50
on the separator wall
42
is broken which causes a gravitational flow of cleaning solution
33
, as shown by arrows A and B, from the first chamber
38
to the second chamber
40
. This, in turn, causes a gravitational flow of the solution
33
from the second chamber
40
through the solution delivery tube
56
, which is attached to the bottom of the second chamber
40
and extends downward through the nozzle
28
, and onto the floor surface
34
. The gravitational flow of cleaning solution onto the floor surface
34
is stopped by disengaging the means for releasing liquid
54
which returns the plunger
52
to its first position and, thereby, seals the aperture
50
in the separator wall
42
.
In the preferred embodiment, the cleaning solution delivery system
32
is a mechanical system. However, the cleaning solution
33
may also be delivered by an electrically powered delivery system that sprays the cleaning solution onto the floor surface
34
(FIGS.
2
and
3
). Further, any system, which adequately delivers the solution
33
to the floor surface
34
, is within the scope of this invention.
Turning now to
FIG. 3
, the motor housing
14
, which contains the power system
58
that supplies a means for suctioning needed to remove the cleaning solution
33
from the floor surface
34
, is best shown. The power system
58
includes a suction motor
60
, an associated suction motor circuit
76
, a power means
62
, such as batteries
64
which also can be rechargeable, cells or a direct AC power source
66
(as shown in FIG.
7
), a pump
68
, a master switch
70
having first and second positions and a gravity switch
72
, such as a mercury switch
74
(as shown in
FIG. 2
) or a weighted micro-switch
82
. A plurality of wires (not referenced but shown) extend between the suction motor
60
, the power means
62
, the pump
68
, the master switch
70
and the gravity switch
72
and provide the necessary electrical connections therebetween. Masters switch means
70
are well known in the art and therefore will not be disclosed in detail herein. It is sufficient to state that when the master switch
70
is in the first position, power is not supplied to the cleaning device
10
.
With continuing reference to
FIG. 3
, the associated suction motor circuit
76
is controlled by the gravity switch
72
. The gravity switch
72
selectively breaks the associated circuit
76
to turn off the suction motor
60
. When the cleaning device
10
is in the scrubbing mode (as shown in FIG.
2
), suction is not needed. Therefore, when the cleaning device
10
is rotated or flipped about its longitudinal axis
11
such that the stationary brush
12
faces the floor surface
34
, the gravity switch
72
automatically breaks the associated circuit
76
to turn off the suction motor
60
. Turning off the suction motor
60
when the device is in the scrubbing mode is desirable because it conserves power. This is especially important when utilizing the battery
64
for the cleaning device
10
. If the suction motor
60
is left on during the scrubbing mode, the continuous power drain will quickly deplete the batteries
64
and the batteries
64
will be drained before the entire floor surface
34
is cleaned. On the other hand, when the cleaning device is in the suction mode, power is needed to turn on the suction motor
60
, which provides the suction needed to remove the dirty cleaning solution from the floor surface
34
. In sum, when the cleaning device
10
is rotated or flipped about its longitudinal axis
11
such that the nozzle
28
faces the floor surface
34
, the gravity switch
72
automatically closes the associated circuit
76
to turn on the suction motor
60
.
In operation, a user activates the cleaning device
10
by moving the master switch
70
from a deactivated position to an activated position. Then, the user rotates the cleaning device
10
about its longitudinal axis
11
such that the stationary brush
12
faces the floor surface
34
. Next, the user engages the means for releasing liquid
54
on the handle to dispense the unused cleaning solution onto the floor surface
34
and the user manually scrubs the floor surface
34
with the stationary brush
12
. After the floor surface
34
is scrubbed, the user rotates the cleaning device
10
about its longitudinal axis
11
, in the preferred embodiment 180° such that the nozzle
28
faces the floor surface
34
. This causes the gravity switch
72
to close the associated suction motor circuit
76
, which turns on the suction motor
60
. The user can then suction the dirty cleaning solution upward through the nozzle
28
as shown by arrows C and D, along the direction of arrows E and F and into the second end
26
of the cleaning housing
22
. A solution reflecting plate
80
can be located in the cleaning housing
22
to deflect the dirty cleaning solution downward in the direction of arrow G and into the recovery tank
84
. The user can repeat this process as many times as is needed until the floor surface
34
is adequately cleaned. Once the floor surface
34
is clean or when the recovery tank
84
is fall, the user can remove cleaning housing
22
from the motor housing
14
to empty and clean the recovery tank
84
.
Turning to
FIGS. 4-6
, a cleaning device having a power driven brush
78
is illustrated by way of example. Except for the power driven brush system
92
, this cleaning device
90
has the same overall configuration as the cleaning device
10
described in the first embodiment of this invention. Therefore, the description for the cleaning device
10
having the stationary brush
12
is included herein by reference and only the power driven brush system
92
will be described in detail.
With reference to
FIG. 6
, the power driven brush system
92
includes a power driven brush
78
, a brush motor
86
and an associated brush motor circuit
88
. A plurality of wires extend between the power driven brush
78
, the brush motor
86
, the power supply
62
and the gravity switch
72
and provide the necessary electrical connections therebetween. In the preferred embodiment, the wires removably connect the brush motor
86
to the gravity switch
72
and the power means
62
so that the cleaning housing
22
can be removed from the motor housing
14
to facilitate emptying and cleaning of the recovery tank
84
. However, the recovery tank
84
may be provided with a cleaning solution removal means (not shown), such as an aperture in the recovery tank (not shown), to allow the tank
84
to be emptied without having to remove the cleaning housing
22
from the motor housing
14
. Such a configuration would enable the brush motor
86
to be hard wired to the gravity switch
72
and the power means
62
.
With specific reference to
FIG. 6
, the gravity switch
72
selectively transfers power from the suction motor
60
to the brush motor
86
. When the cleaning device
90
is in the scrubbing mode, power must be supplied to the power driven brush
78
to facilitate scrubbing of the floor surface
34
. Therefore, when the cleaning device
90
is rotated or flipped about its longitudinal axis
11
such that the power driven brush
78
faces the floor surface
34
, the gravity switch
72
automatically breaks the associated suction motor circuit
76
to turn off the suction motor
60
and simultaneously closes the associated brush circuit
88
to turn on the brush motor
86
. On the other hand, when the cleaning device is in the suction mode, power is needed to turn on the suction motor
60
, which provides the suction needed to remove the dirty cleaning solution from the floor surface
34
. Therefore, when the cleaning device
90
is rotated or flipped about is longitudinal axis
11
such that the nozzle
28
faces the floor surface
34
, the gravity switch
72
automatically breaks the associated brush motor circuit
88
to turn off the brush motor
86
and simultaneously closes the associated suction motor circuit
76
to turn on the suction motor
60
.
In operation, a user activates the cleaning device
90
by moving the master switch
70
from the first position to the second position. Then, the user rotates or flips the cleaning device
90
about its longitudinal axis
11
such that the power driven brush
78
faces the floor surface
34
, which turns on the brush motor
86
. Next, the user engages the means for releasing liquid
54
on the handle
20
to dispense the unused cleaning solution on the floor surface
34
and the user uses the power driven brush
78
to scrub the floor surface. After the floor surface is scrubbed, the user rotates or flips the cleaning device
90
about its longitudinal axis
11
such that the nozzle
28
faces the floor surface
34
. This causes the gravity switch
72
to turn off the brush motor
86
and to simultaneously turn on the suction motor
60
. The user can then use the nozzle
28
to suction the dirty cleaning solution off the floor surface
34
and into the recovery tank
84
. The user can repeat this process as many times as is needed until the floor
34
surface is adequately cleaned. Once the floor surface
34
is clean, the user can remove cleaning housing
22
from the motor housing
14
to empty and clean the recovery tank
84
.
In the preferred embodiment, separate motors drive the power driven brush
78
and the pump
68
. However, a single motor (not shown) can power both the power driven brush
78
and the pump
68
. In this configuration, the gravity switch
72
would selectively transfer power from the single motor to either the power driven brush
78
or the pump
68
.
The invention has been described with reference to two preferred embodiments. Obviously, modifications and alterations will occur to others upon a reading and understanding of this specification. It is intended to include all such modifications and alternations in so far as they come within the scope of the appended claims or the equivalence thereof.
