EMBODIMENTS
[0037] Combining with the drawings and detailed embodiments, the
present invention is further elaborated:
Embodiment 1
[0038] As shown in FIG. 1 and FIG. 2, a washing machine, taking a
roller washing machine as an example for detailed description in
the embodiment, comprises a shell (not shown in the figure), an
outer tub 1, an inner tub 2 arranged in the shell, and solid
particles 3 as washing medium. Wherein, the outer tub 1 is fixed,
mainly for holding water, and the inner tub 2 is arranged at the
inner of the outer tub 1 for washing and is driven to rotate by a
driving device 4. A water inlet (not shown in the figure) is
arranged on the upper of the outer tub 1 for water inflow during
washing and rinsing, and a water outlet (not shown in the figure)
is arranged on the lower of the outer tub 1 for water draining
after dewatering.
[0039] To be convenient for separating clothes 5 from particles 3,
a circle of isolation tub 6 is arranged along the inner side of the
inner tub 2 optionally. The clothes 5 are placed in the isolation
tub 6. The bottom and top of the isolation tub 6 are fixedly
connected with the bottom and top of the inner tub 2 respectively
by fastenings, and rotate with the inner tub 2 synchronously. The
isolation tub 6 is a net structure, so as to let the particles 3
and washing water flow in and out easier. The clothes 5 are
isolated in the isolation tub 6, while the particles 3 are isolated
between the isolation tub 6 and the inner tub 2. During washing,
the particles 3 pass through the isolation tub 6 to fully mix with
the clothes 5. Preferably, the particles 3 are made of polymer
material with porous surface. With the preferable adsorption
capacity of the particles 3, the dirt in the clothes 5 and washing
water is adsorbed, thus reaches a preferable washing effect.
[0040] As with the ordinary roller washing machine, at least a
lifting block 7 protruding inward is arranged in the inner wall of
the isolation tub 6. During the washing, under the action of the
lifting block 7, the clothes 5 turn up and down continually in the
inner tub 2, lifting and then falling down, to achieve the washing
effect in cycles. The number of the lifting block 7 may be 1-3. In
the embodiment, it's preferred to adopt 3 lifting blocks 7, which
are arranged evenly along the circumference of the isolation tub
6.
[0041] On the inner wall of the inner tub 2, multiple lifting ribs
8 protruding inward are arranged in parallel. The lifting ribs 8
are arranged on the inner wall of the inner tub 2 obliquely and
bend along the arc of the wall of the inner tub 2. The line between
the two end points of the lifting ribs 8 forms an included angle
relative to the axis of the inner tub 2. The included angle may be
an acute angle or an obtuse angle, i.e. the lifting ribs 8 incline
upward or downward along the wall of the inner tub 2. The lifting
ribs 8 rotate with the inner tub 2, and drive the particles 3 as
washing medium to move obliquely upward or downward along the
lifting ribs 8. When the movement reaches a certain height, the
particles 3 fall from the lifting ribs 8 to the inner tub 2, and to
achieve overturn.
[0042] To avoid damaging the particles 3, in the embodiment, the
cross section of the lifting ribs 8 is preferably streamline shape
which roughly circular arc in shape. The diameter of the particles
3 is in the range of around 2-3 mm. The height of the lifting ribs
8 is preferably at least 5 mm, slightly less than or equal to the
distance between the inner wall of the inner tub 2 and the outer
wall of the isolation tub 6. The number of the lifting ribs 8 is
1-10, 5-8 preferably, which are arranged evenly along the wall of
the inner tub 2. With more and higher lifting ribs 8, more
particles 3 can be driven.
[0043] When washing the clothes 5, the inner tub 2 rotates
clockwise and counterclockwise in turn. Under the action of
centrifugal force, the particles 3 move obliquely upward or
downward along the lifting ribs 8, move forward and backward and
turn over along the axis of the inner tub 2 continually in the
inner tub 2 to blend with the clothes 5 more fully, thereby
improving cleaning rate. At this moment, the rotating speed of the
inner tub 2 is no need to be very high. Washing speed is enough.
Generally, it optionally rotates at a speed of 50-150 r/min. In the
meantime, when recycling the particles 3, driving the inner tub 2
to run continuously in the direction opposite to the inclined
direction of the lifting ribs 8, thus the particles 3 is driven to
move toward the front end of the inner tub 2 by the lifting ribs 8.
Finally the particles 3 flow out of the inner tub 2 via a discharge
port 9 located on the front end of the inner tub 2, and flow into
the outer tub 1. In the process, the inner tub 2 is chosen to
rotate at a speed of 50-150 r/m.
[0044] A air circulation channel 10 is arranged in the shell of the
washing machine, and both ends of the air circulation channel 10
communicate with the inner tub 2. A fan 11 is arranged in the air
circulation channel 10 for blowing toward the inner tub 2, so as to
separate the clothes 5 from the particles 3.
[0045] An air outlet 12 of the air circulation channel 10 is
arranged on the rear wall of the outer tub 1 while an air inlet 13
of the air circulation channel 10 is arranged on the front wall of
the outer tub 1. A number of openings for the washing water flowing
through are arranged evenly on the side wall, bottom wall and front
wall of the inner tub 2. the diameter of the openings is less than
that of the solid particles 3. The shape of the openings may be
round, rectangle or polygon and so on. The air from the air outlet
12 on the rear wall of the outer tub 1 flows into the inner tub 2
via the openings on the bottom wall of the inner tub 2, then flows
out of the openings on the front wall of the inner tub 2, and
finally flows into the air circulation channel 10 through the air
inlet 13 on the front wall of the outer tub 1, thus forms a air
circulation path with entering air from the rear side of the inner
tub 2 while blowing air out from the front side.
[0046] A storage tank 15 is arranged on the outer wall of the outer
tub 1 for storing the particles 3, and the storage tank 15 is fixed
on the top or one side of the outer tub 1. The storage tank 15
connects with the inner space of the outer tub 1 via a port 16
arranged on the wall of the outer tub 1. Or a valve is arranged at
the port 16 for controlling the opening/closing of the port 16.
[0047] For the benefit of recycling the particles 3, in the
embodiment, at least one scraper 17 protruding outward is arranged
on the outer wall of the inner tub 2, and the scraper 17 is used
for pushing the particles 3 to enter into the outer tub 1 from the
inner tub 2. The number of the scraper 17 may be 1-3. In the
embodiment, it's preferred to adopt 3 scrapers 17, which are
distributed evenly along the circumference of the inner tub 2. The
radial height of the scraper 17 is slightly lower than the distance
between the outer wall of the inner tub 2 and the inner wall of the
outer tub 1, which may avoid the scraper 17 touching the inner wall
of the outer tub 1 during the rotation of the inner tub 2. The
axial length of the scraper 17 is roughly equal to that of the
inner tub 2. When recycling the particles 3, the inner tub 2
rotates at a high speed, which results in producing a large
centrifugal force. Under the centrifugal force, the particles 3 of
the outer tub 1 flow at a high speed along the inner wall of the
outer tub 1, and is thrown into the storage tank 15 through the
port on the wall of the outer tub. The scraper 17 continually
pushes the particles 3 to flow, which is more beneficial for the
recycling of particles 3.
[0048] The storage tank 15 is connected with a feeding hole 14 of
the inner tub 2 via a feeding channel 18, and the feeding hole 14
is arranged above the door 19 of the washing machine. A feeding
valve is arranged on the feeding hole 14 or the feeding channel 18.
For the benefit of putting in the particles 3, a delivery pump (not
shown in the figure) also is arranged on the feeding channel 18.
The discharge hole 9 of the inner tub 2 is arranged at the window
pad below the door 19 of the washing machine, and connected with
the inner space of the outer tub 1. A discharge valve 20 is
arranged at the discharge hole 9.
[0049] Combining FIGS. 1-4, the washing method of the aforesaid
roller washing machine is further described.
[0050] The washing method comprises the following steps:
[0051] Step I: Putting the clothes 5 to be washed into the
isolation tub 6 of the washing machine, and opening the water inlet
above the outer tub 1 for adding washing water; the washing water
mixed with detergent flows into the outer tub 1; through the
openings on the inner tub 2 and the isolation tub 6, the water
flows into the isolation tub 6 and mixes with the clothes 5 to be
washed fully. In the process, it's only needed to add in moderate
water and detergent to ensure the clothes 5 to be soaked in the
water.
[0052] When injecting washing water to soak the clothes 5 to be
washed, the clothes 5 are soaked for a certain time. Thus the
clothes 5 is fully infiltrating with water so as to further improve
the washing effect.
[0053] Step II: Starting the delivery pump for the particles 3, and
opening the feeding valve, thus the particles 3 in the storage tank
15 are driven to be put into the inner tub 2 via the feeding
channel 18 by the delivery pump.
[0054] In the step, the inner tub 2 rotates at a low speed of
50-150 r/min, which is beneficial to the full contact between the
particles 3 in the inner tub 2 and the clothes 5.
[0055] Step III: After all the particles 3 are put into the inner
tub 2, the putting in the particles ends, and the feeding valve is
close. This process may be controlled by restricting the putting
time.
[0056] The inner tub 2 is driven to rotate clockwise for a period
of time, stop, and then rotate counterclockwise for a period of
time by the driving device 4. Likewise, the lifting ribs 8 rotate
clockwise and counterclockwise alternately too, thus, the particles
3 move forward or backward continually in the inner tub 2. The
particles 3 move obliquely upward along the lifting ribs 8, and
when reaching a certain height, the particles 3 flip down and fall
into the inner tub 2. It is achieved to overturn in forward and
backward directions. During the washing, under the impact of the
lifting block 7, the clothes 5 turn up and down.
[0057] During the washing, the particles 3, clothes 5 and washing
water are fully blended, lift and decline continually under the
impact of the lifting blocks 7 and the lifting ribs 8, thereby
finishing the washing of the clothes 5.
[0058] In this step, when the rotating speed of the inner tub 2 is
between 100-200 r/min, it can obtain the best effect.
[0059] Step IV: After the washing, the water is drained, and the
clothes 5 is separated from the particles 3 and washing water
preliminarily.
[0060] Step V: The inner tub 2 rotates at a high speed, and clothes
5 and particles 3 in the inner tub 2 simultaneously dewater. The
recycling of the particles 3 is achieved. The washing water is
collected in the outer tub 1 and discharged via the water outlet of
the bottom of the outer tub 1.
[0061] In this step, the inner tub rotates 2 at a speed of 100-1000
r/min, generally higher than the speed during washing.
[0062] Step VI: After dewatering, the fan 11 is started. The air
along the air circulation channel 10 blows into the inner tub 2
from the air outlet 12 on the rear wall of the outer tub 1 via the
openings on the bottom wall of the inner tub 2; and the air blows
toward the clothes 5 and particles 3 in the inner tub 2. The
clothes 5 are separated from the particles 3 preliminarily under
the action of the air.
[0063] The air flows out from the openings of the front wall of the
inner tub 2, and finally flows into the air circulation channel 10
from the air inlet 13 of the front wall of the outer tub 1, thus
forms air circulation.
[0064] Meanwhile, opening the feeding valve 20, and the inner tub 2
is driven to run continuously in the direction opposite to the
inclined direction of the lifting ribs 8. Thus, the particles 3 are
driven to move toward the discharge hole 9 of the front of the
inner tub 2 by the lifting ribs 8, and flow into the space between
the outer tub 1 and the inner tub 2 through the discharge hole
9.
[0065] In the process, the inner tub 2 rotates at a speed of 50-150
r/min.
[0066] Step VII: the inner tub 2 rotates at a high speed again.
Under the centrifugal force, the particles 3 in the outer tub 1
flow at a high speed along the inner wall of the outer tub 1, and
are thrown into the storage tank 15 from the port 16 on the wall of
the outer tub 1, finishing the recycling of the particles 3.
[0067] Step VIII: Rinsing step, adding clean water into the outer
tub 1 again, and the inner tub 2 is driven to rotate. The clothes 5
is rinsed, and draining the water after rinsing. Then the inner tub
2 rotates at a high speed to dewater the clothes 5.
[0068] Other structures and working process are the same as
Embodiment 1, thereby no additional detailed description here.
Embodiment 2
[0069] As shown in FIG. 5, the difference from Embodiment 1 is that
the air outlet 12 of the air circulation channel 10 is arranged on
the rear wall of the outer tub 1 while its air inlet 13 is arranged
on the door 19 of washing machine. An air channel 21 for leading
the air from the inner tub 2 to the air circulation channel 10 is
arranged on the door 19 of the washing machine. One end of the air
channel connects with the inner tub 2 while the other end connects
with the air circulation channel 10. Thus, no need to arrange the
port on the front wall of the inner tub 2, and arranging several
ports on the bottom wall of the inner tub 2 is enough.
[0070] The air along the air circulation channel 10 blows into the
inner tub 2 from the air outlet 12 on the rear wall of the outer
tub 1 via the openings on the bottom wall of the inner tub 2. The
air blows toward the clothes 5 and particles 3 in the inner tub 2.
And, the clothes 5 are driven to be separated from the particles 3
preliminarily by the air.
[0071] Then the air flows out of the air channel 21 on the door 19
of the washing machine ahead the inner tub 2, and flows into the
air circulation channel 10, forming air circulation.
Embodiment 3
[0072] As shown in FIG. 6, a channel 22 is set on the door 19 of
the washing machine. One end of the channel 22 is communicated with
the inner tub 2 via the feeding hole 14 while the other end
connected with the feeding channel 18. The channel 22 is slightly
tilted upward, avoiding the particles 3 entering the channel 22
during washing.
[0073] When putting in the particles 3, the delivery pump and the
feeding valve are started simultaneously. Thus, the particles 3 in
the storage tank 15 are put into the inner tub 2 via the feeding
channel 18 and the channel 22 on the door 19 of the washing machine
by the delivery pump.
Embodiment 4
[0074] The difference from the aforesaid embodiment is that the
number of the lifting rib 8 is one, which is spirally arranged
along the inner wall of the inner tub 2 from the bottom to the top
of the inner tub 2.
Embodiment 5
[0075] The difference from the aforesaid embodiment is that the
storage tank 15 is fixed above the outer tub 1, and the discharge
hole of the storage tank 15 is connected with the feeding hole 14
of the inner tub 2 of the washing machine via the valve. When the
valve is open, the particles 3 enter in the inner tub 2 from the
storage tank 15 depending mainly on the gravity.
[0076] As aforesaid, combining the scheme provided by the drawings,
similar technical scheme may be derived. However, without departing
from the technical scheme of the present invention, any tiny
modification, equivalent change or alteration on the aforesaid
embodiments based on the technical essence of the present
invention, still belongs to the scope of the present invention.
