Description
FIELD OF TECHNOLOGY
[0001] The present invention relates to washing devices for
sweeping and washing a floor concurrently or for washing window
glass in an electrically driven manner, and more particularly, to
an electric sweeping washing device for sweeping and scrubbing the
floor and/or rug concurrently and washing windows.
BACKGROUND
[0002] Due to technological advancement, there is wide use of the
existing art pertaining to cleaning, an indoor environment, such as
the floor, with an automated cleaning machine, wherein control
logic of a mobile robot enables the cleaning machine capable of
vacuum cleaning or floor washing to roam within a space to be swept
and cleaned the floor in an automated manner.
[0003] The aforesaid conventional automated cleaning machines fall
into two categories, namely floor sweeping machines and floor
washing machines. The floor sweeping machines remove dust from the
floor by sweeping and vacuum cleaning the floor, but fail to remove
tiny dust and smear from the floor or rug. Hence, it is necessary
to remove tiny dust and smear with the floor washing machines.
[0004] However, according to the existing art, before its operation
begins, automated floor washing machines require spraying a
cleaning solution or clean water onto the floor in an automated
manner, scrubbing the floor with a roller brush, and collecting
dirty water from the floor with a scraper installed behind the
roller brush to thereby finalize floor washing. However, during the
aforesaid cleaning process, as long as dirty water which results
from scrubbing the floor remains on the floor, the floor will still
look dirty after the dirty water has dried up, whereas a portion of
the floor is likely to absorb water or has a crack, and in
consequence dirty water will be kept inside the crack. Moreover,
all the existing robotic floor washing machines assertedly claim
the capability of recycling 50% of the dirty water on the floor but
leaving behind the other 50% of the dirty water on the floor.
Hence, it is impossible to wash and clean the floor thoroughly.
Since the rug absorbs water, water must not be sprayed onto the
rug; hence, it is impossible for the robotic floor washing machine
to remove a smear from the rug.
[0005] The Electronic Sweeping Washing Device is a revolutionized
floor, rug, and window washing machine. It can sweep and scrub on
flat surface and rug concurrently for faster and cleaner result.
The Electronics Sweeping Washing Device is time-saving,
labor-saving, cost-saving, and space-saving. The Electronics
Sweeping Washing Device offers changeable brush for floor and rug
with option brush for window cleaner purpose. The sweep washing
device is designed to clean with fresh water or wash fluid that
spray over the brush surface and vacuumed out the dirty liquid
directly to liquid container without landing dirty water to the
washing area. For window cleaner simply uses option window brush to
clean the windows or tiles.
SUMMARY
[0006] From a user's perspective, conventional tools for use in
washing windows, floors, and rugs are difficult to operate,
time-consuming, and laborious, not to mention that they have to
work in conjunction with various single-function machines.
[0007] With multiple function of Electronics Sweep Washing Device
allows user sweeps and washes the floor and the rug easily and
quickly, and in a cost-saving, labor-saving, and space-saving
manner. Furthermore, the electric sweeping washing device removes
smears and tiny dust from the floor and the rug while sweeping the
floor and the rug, and can change to option window brush to
function as an electric window washer. The electric sweeping
washing device prevents dirty water from landing on the floor.

come in the form of springs or any other equivalent structures. The
buffer devices are not regarded as an essential technical feature
of the present invention and thus are not described in detail
hereunder for the sake of brevity. While the water absorbing
scrubbing roller brush 120a is rotating, the buffer devices adjust
the degree of tight contact between the water absorbing scraper 140
and the water absorbing scrubbing roller brush 120a, such that the
water absorbing scrubbing roller brush 120a not only rotates
smoothly but also functions well. The water absorbing scrubbing
roller brush 120a and the sweeping roller brush 160a are changeable
as needed.
[0039] The sweeping washing brush 100a comprises a storage battery
180 and a recharging plug 190 electrically connected to the storage
battery 180. The storage battery 180 supplies power to the sweeping
washing brush motor 121a to drive the sweeping washing brush motor
121a to rotate. A user can insert the recharging plug 190 into a
recharger (not shown) to recharge the storage battery 180.
[0040] The water collection system design 200 comprises a tank 210,
a clean water chamber 220, a dirty water chamber 230, a pipe 240, a
spray motor 250, and an air intake motor 260.
[0041] The clean water chamber 220 is disposed inside the tank 210
and contains clean water available for use.
[0042] The dirty water chamber 230 is disposed inside the tank 210
and contains dirty water which results from clean water usage.
[0043] The pipe 240 comprises therein a spray tube 241, a water
absorbing tube 242, and a dust sucking tube 243. The spray tube 241
connects the sprinkler head 130 to the spray motor 250 and the
clean water chamber 220.
[0044] The water absorbing tube 242 connects the water absorbing
scraper 140 and the dirty water chamber 230. The dust sucking tube
243 connects the sweeping washing brush front 111a and the water
absorbing tube 242 to the dirty water chamber 230.
[0045] The spray motor 250 is disposed at the tank 210 to withdraw
unused clean water from the clean water chamber 220 with the spray
tube 241. Then, the unused clean water thus withdrawn is driven and
delivered to the sprinkler head 130 by means of the spray motor
250.
[0046] The air intake motor 260 is disposed at the tank 210 to
reduce the internal pressure of the dirty water chamber 230 to
vacuum pressure, such that the used dirty water is raked by the
water absorbing scraper 140 and delivered to the dirty water
chamber 230 by means of the water absorbing tube 242; meanwhile,
dirt and dust is raked by the sweeping washing brush front 111a and
delivered to the dirty water chamber 230 by means of the dust
sucking tube 243 and the water absorbing tube 242.
[0047] The electric sweeping washing device 1000 sweeps and washes
the floor 2 by following the steps described hereunder. The
sweeping roller brush 160a is driven by the sweeping washing brush
motor 121a to rotate and start sweeping the floor and the rug 2;
meanwhile, the water absorbing scrubbing roller brush 120a is also
driven by the sweeping washing brush motor 121a to scrub the floor
or rug 2. Furthermore, the sprinkler head 130 sprinkles unused
clean water on the water absorbing scrubbing roller brush 120a
continuously to thereby rinse the water absorbing scrubbing roller
brush 120a. Furthermore, the water absorbing scraper 140 collects
dust-containing and dirt-containing dirty water from the water
absorbing scrubbing roller brush 120a and conveys the dirty water
to the dirty water chamber 230 continuously. In so doing, the water
absorbing scrubbing roller brush 120a is kept clean and wet all the
time and therefore fit to clean the floor or rug 2 repeatedly.
[0048] Referring to FIG. 1 through FIG. 4, the user cleans the
floor or rug 2 with the sweeping washing brush 100a by following
the steps described hereunder.
[0049] First, the sweeping roller brush 160a sweeps most of the
dust, dirt, and hair into the sweeping washing brush front 111a.
Then, the dust, dirt, and hair ends up in the dust sucking tube 243
by suction, because the air intake motor 260 reduces the internal
pressure of the dirty water chamber 230 to vacuum pressure.
Afterward, the dust, dirt, and hair enters the water absorbing tube
242 and be mixed with the dirty water before being collected and
stored in the dirty water chamber 230.
[0050] The water absorbing scrubbing roller brush 120a scrubs the
floor or rug 2 to rake the dust and smears spared by the sweeping
roller brush 160a.
[0051] The clean water stored in the clean water chamber 220 is
withdrawn by the spray motor 250 and delivered via the spray tube
241 to the sprinkler head 130, such that the sprinkler head 130
sprinkles the clean water onto the water absorbing scrubbing roller
brush 120a to thereby wash off the dust or dirt otherwise attached
to the water absorbing scrubbing roller brush 120a as a result of
its scrubbing the floor.
[0052] Due to the vacuum pressure generated by the air intake motor
260, dust-containing and dirt-containing dirty water on the water
absorbing scrubbing roller brush 120a is raked by the water
absorbing scraper 140 and delivered via the water absorbing tube
242 to the dirty water chamber 230.
[0053] Before starting to sweep and wash the floor and the rug with
the electric sweeping washing device 1000, the user takes out the
clean water chamber 220 and fills it with clean water.
[0054] When the clean water is going to run out and the dirty water
chamber 230 is going to be full of dirty water, the user may take
out the dirty water chamber 230 and empty it. In doing so, the
sweeping roller brush 160a is capable of sweeping the floor and the
rug continuously, and the water absorbing scrubbing roller brush
120a is kept clean all the time. A plurality of mobile rollers 270
is disposed at the bottom of the tank 210. The mobile rollers 270
enable the user to move the water collection system design 200 of
the electric sweeping washing device 1000 easily.
[0055] Persons skilled in the art are able to infer from FIG. 5
that the sprinkler head 130 is positioned on one side of the water
absorbing scrubbing roller brush 120a, and that the water absorbing
scraper 140 is positioned on the other side of the water absorbing
scrubbing roller brush 120a. Hence, not only is the water absorbing
scrubbing roller brush 120a cleaned efficiently, but the water
absorbing scraper 140 can also remove and rake the dirty water on
the water absorbing scrubbing roller brush 120a efficiently.
[0056] Referring to FIG. 6, there is shown a schematic view of the
electric sweeping washing device 1000, wherein the brush is
changed. The electric sweeping washing device 1000 is
advantageously characterized in that the user can connect the
washing brush 100 or the sweeping washing brush 100a to the pipe
240 and the water collection system design 200 as needed. The
washing brush 100 or the sweeping washing brush 100a is connected
to the pipe 240 by a mortise-and-tenon joint. For example, the pipe
240 has therein a recess, wherein the washing brush 100 or the
sweeping washing brush 100a has thereon a protruding post
corresponding in position to the recess.
[0057] In conclusion, the electric sweeping washing device of the
present invention sweeps, vacuum-cleans, and scrubs the floor
concurrently and thus speeds up the aforesaid cleaning process
efficiently.
[0058] Furthermore, with the water absorbing scrubbing roller brush
being clean and wet all the time, the user can sweep and wash the
floor or rug easily, quickly, and in a labor-saving manner.
Furthermore, with the electric sweeping washing device, the user
performs floor sweeping and floor washing concurrently, thereby
dispensing the hassle of operating various single-function floor
sweeping devices, floor washing devices, vacuum cleaning devices,
and rug cleaning devices; hence, the electric sweeping washing
device is time-saving, labor-saving, and cost-saving. Furthermore,
the electric sweeping washing device in operation prevents dirty
water from landing on the floor; hence, not only does the floor
thus swept and washed display no trace of residue, but the rug thus
swept and washed also dries quickly to thereby extend its service
life.
[0059] Referring to FIG. 7, the water absorbing scrubbing roller
brush 120a of the sweeping washing brush 100a comprises a first
gear 122, whereas the sweeping roller brush 160a of the sweeping
washing brush 100a comprises a second gear 123. The first gear 122
and the second gear 123 together form a gear train. As soon as the
sweeping washing brush motor 121a drives the water absorbing
scrubbing roller brush 120a to rotate, the first gear 122 drives
the second gear 123 to rotate, thereby causing the sweeping roller
brush 160a to rotate.
[0060] Referring to FIG. 8, a rotation element 280 is disposed at
the junction of the body 110 of the sweeping washing brush 100a and
the pipe 240 of the water collection system design 200. The
rotation element 280 enables the pipe 240 to rotate about the
junction and relative to the body 110 and thus be readily
accessible by a user.
[0061] Referring to FIG. 9 through FIG. 13, there are shown
schematic views of an electric sweeping washing device 3000
according to the second embodiment of the present invention. The
electric sweeping washing device 3000 is for use in washing a
window 1. The electric sweeping washing device 3000 comprises a
washing brush 100 and a water collection system design 200.
[0062] The washing brush 100 comprises a body 110, a water
absorbing scrubbing roller brush 120, and a sprinkler head 130.
[0063] The body 110 has a washing brush casing 111. The opening of
the washing brush casing 111 faces the window 1, as shown in FIG.
13.
[0064] The water absorbing scrubbing roller brush 120 is disposed
inside the washing brush casing 111 and driven by a washing brushed
motor 121 to rotate.
[0065] The sprinkler head 130 is disposed inside the washing brush
casing 111. The sprinkler head 130 faces the water absorbing
scrubbing roller brush 120 and washes off tiny dust and dirty water
otherwise adhered to the water absorbing scrubbing roller brush 120
as a result of scrubbing the window glass, thereby keeping the
water absorbing scrubbing roller brush 120 clean and wet enough to
remove tiny dust and smears otherwise adhered to the window
glass.
[0066] The water absorbing scraper 140 is disposed inside the
washing brush casing 111 and presses against the water absorbing
scrubbing roller brush 120 so as for the water absorbing scraper
140 to rake dirty water and tiny dust on the water absorbing
scrubbing roller brush 120a.
[0067] At the two ends of the water absorbing scraper 140 are
buffer devices (not shown) which come in the form of springs or any
other equivalent structures. While the water absorbing scrubbing
roller brush 120 is rotating, the buffer devices adjust the degree
of tight contact between the water absorbing scraper 140 and the
water absorbing scrubbing roller brush 120, such that the water
absorbing scrubbing roller brush 120 not only rotates smoothly but
also functions well. The water absorbing scrubbing roller brush 120
is changeable as needed.
[0068] The washing brush 100 comprises a storage battery 180 and a
recharging plug 190 electrically connected to the storage battery
180. The storage battery 180 supplies power to the washing brushed
motor 121 to drive the washing brushed motor 121 to rotate. The
user can insert the recharging plug 190 into a recharger (not
shown) to recharge the storage battery 180.
[0069] The water collecting scraper 150 is disposed beside the
opening of the washing brush casing 111 and disposed above the
opening of the washing brush casing 111.
[0070] The water collection system design 200 has a tank 210.
[0071] The clean water chamber 220 is removably disposed inside the
tank 210 and adapted to contain the unused clean water.
[0072] The dirty water chamber 230 is removably disposed inside the
tank 210 and adapted to contain the used dirty water.
[0073] The pipe 240 comprises therein a spray tube 241 and a water
absorbing tube 242. The spray tube 241 connects the sprinkler head
130 and the clean water chamber 220. The water absorbing tube 242
connects the water absorbing scraper 140 and the dirty water
chamber 230.
[0074] The spray motor 250 is disposed at the tank 210 to withdraw
unused clean water from the clean water chamber 220 with the spray
tube 241. Then, the unused clean water thus withdrawn is driven and
delivered to the sprinkler head 130 by means of the spray motor
250.
[0075] The air intake motor 260 is disposed at the tank 210 to
reduce the internal pressure of the dirty water chamber 230 to
vacuum pressure, such that the used dirty water is raked by the
water absorbing scraper 140 and delivered to the dirty water
chamber 230 by means of the water absorbing tube 242. A plurality
of mobile rollers 270 is disposed at the bottom of the tank 210.
The mobile rollers 270 enable the user to move the water collection
system design 200 of the electric sweeping washing device 1000
easily.
[0076] The process of cleaning the window 1 with the electric
washing device 3000 entails following the steps described
hereunder. The water absorbing scrubbing roller brush 120 of the
washing brush 100 is driven by the washing brushed motor 121 to
scrub the window 1. The sprinkler head 130 faces the water
absorbing scrubbing roller brush 120 and washes off tiny dust and
dirty water otherwise adhered to the water absorbing scrubbing
roller brush 120 as a result of scrubbing the window 1, thereby
keeping the water absorbing scrubbing roller brush 120 clean and
wet enough to remove the tiny dust and smears from the window 1
repeatedly. The water absorbing scraper 140 presses against the
water absorbing scrubbing roller brush 120 in order to rake dirty
water and tiny dust and delivers to the dirty water chamber 230 the
dirt and dirty water adhered to the water absorbing scrubbing
roller brush 120 as a result of scrubbing the window 1. Hence, the
water absorbing scrubbing roller brush 120 is kept clean all the
time and thus fit to clean the window 1 repeatedly.
[0077] Referring to FIG. 9 through FIG. 13, there are shown
schematic views of operation of the electric sweeping washing
device according to the third embodiment of the present invention,
wherein the washing brush 100 and the window 1 are shown.
[0078] During the process of cleaning the window 1 with the water
absorbing scrubbing roller brush 120, the clean water stored in the
clean water chamber 220 is taken in by the spray motor 250,
delivered by the spray tube 241, and sprinkled by the sprinkler
head 130 onto the water absorbing scrubbing roller brush 120 to
thereby remove dust or dirt from the water absorbing scrubbing
roller brush 120.
[0079] The air intake motor 260 reduces the internal pressure of
the dirty water chamber 230 to vacuum pressure, such that the water
absorbing scraper 140 rakes dust-containing or dirt-containing
dirty water on the water absorbing scrubbing roller brush 120 and
delivers the dirty water to the water absorbing tube 242, and in
consequence the dirty water is collected in the dirty water chamber
230. Furthermore, redundant water on the window 1 is efficiently
removed by the water collecting scraper 150 and absorbed by the
scrubbing roller brush.
[0080] Before starting to use the electric sweeping washing device
3000, the user may take out the clean water chamber 220 and fill it
with clean water (i.e., unused clean water.)
[0081] After the clean water has run out and turned into dirty
water (i.e., used dirty water) and thus has been stored in the
dirty water chamber 230, the user can take out the dirty water
chamber 230 and empty the dirty water chamber 230. Hence, to clean
the window 1, it is not necessary for the user to sprinkle clean
water onto the window 1 or wash a wiper before scrubbing the window
1.
[0082] Furthermore, the water absorbing scrubbing roller brush 120
is kept clean all the time and driven by the washing brushed motor
121 to scrub the window 1 continuously. Referring to FIG. 13, the
sprinkler head 130 is disposed on one side of the water absorbing
scrubbing roller brush 120, whereas the water absorbing scraper 140
is disposed on the other side of the water absorbing scrubbing
roller brush 120. In so doing, not only is the water absorbing
scrubbing roller brush 120 cleaned efficiently, but the water
absorbing scraper 140 also removes dirty water from the water
absorbing scrubbing roller brush 120 efficiently.
[0083] In conclusion, the present invention provides an electric
washing device characterized by a sprinkler head, a water absorbing
scraper, a clean water chamber, a dirty water chamber, and a pipe
which together keep a water absorbing scrubbing roller brush clean
all the time, such that a user cleaning a window need not sprinkle
water onto the window or rinse a wiper repeatedly in order to clean
the window glass. Accordingly, the electric washing device of the
present invention is effective in speeding up the cleaning process
and preventing dirty water from landing on the floor.
