Description
FIELD OF THE INVENTION
[0001] The present invention refers to a washing machine, in
particular to a washing machine using polymer adsorption materials
for washing as well as the washing method thereof. The present
invention belongs to the field of washing machine technology.
BACKGROUND OF THE INVENTION
[0002] In the washing method of a traditional washing machine, the
washing medium is water, adding water and detergents into the
washing machine for washing; after washing, discharging the sewage
from the washing machine via dewatering function, and then adding
clean water again for continuing the washing or rinsing process,
finally discharging water after the washing is entirely finished.
In this method, the water is simply discharged and then the clean
water is refilled, thus causes large water consumption. Meanwhile,
lots of chemical substances which are harmful to the environment
are contained in the washing liquid and the washing process is
time-consuming, with large power consumption each time.
[0003] To overcome the shortcomings of the aforesaid traditional
washing method, in the prior art, some washing machines use an
organic solvent as the medium, for example, a dry cleaning machine,
in which the organic solvent is recycled. After the completion of
one washing process, the organic solvent containing dirt is
collected in a container, disposed by filtration and distillation,
and then put back into the washing tub to continue the washing
process. Due to the high toxicity of the organic solvent and the
relatively low safety factor of medium recovery by distillation, it
is not suitable for household use.
[0004] There is another washing method by using air in the prior
art, such as CO.sub.2. In this method, the medium is required to
achieve the phase changes between gas and liquid, that is, medium
is used for washing in liquid phase and then recycled in gas phase.
The method demands not only a highly airtight structure, but also a
high pressure for liquefying gas, which requires a high-pressure
installation, so it is of low safety factor and complex
process.
[0005] To overcome the shortcomings of the aforesaid washing
methods, a washing method with the specially-made solid particles
as the washing medium is provided, in which the dirt on clothes is
adsorbed and then removed through the friction between the solid
particles and clothes, so as to achieve the purpose of washing. The
washing method can save over 80% water. Moreover, the solid
particles as washing medium can be recycled and reused with a long
service life, having no need to change and being safe and
environmentally friendly. Generally, a washing machine that uses
the washing method is generally arranged with a storage space of
particles as well as a feed opening and a discharge opening on the
outer tub. Before washing, the particles is put into the outer tub
from the feeding opening, and then recycled back into the storage
space of particles fully after washing. The washing method has some
shortcomings. During the washing, the friction between the
particles and the clothes can cause the clothes to wear to a
certain degree. In addition, the particles should be put in the
inner tub before washing and then recycled after washing. If
particles are needed to dehydrate, the particles are required to be
put and recycled again, which cause a complex washing process. And
the inner structure of the washing machine needs to be improved
vastly accordingly, thereby the material and manufacturing costs
are required to increase greatly.

EMBODIMENTS
[0038] The present invention is further described in combination
with the attached drawings and specific embodiments:
[0039] As shown in FIGS. 1 and 2, a washing machine, both a
pulsator washing machine and a roller washing machine in present
use, comprises a shell (not shown in figures), in which an outer
tub 1 and an inner tub 2 are arranged. The washing tub in the
present invention may be the inner tub 2 for washing or the outer
tub 1 for containing water. Wherein, the outer tub 1 is a closed
structure, and fixed without rotating; the inner tub 2 is arranged
inside the outer tub 1. The wall of the inner tub 2 is provided
with a plurality of first opening holes 4 with round, rectangle or
polygon etc. in shape, for the washing water flowing through. The
inner tub 2 may be driven to rotate by a driving device. On the
upper side of the outer tub 1, a water inlet (not shown in figure)
is arranged for water inflow during washing and rinsing. On the
lower side of the outer tub 1, a water outlet (not shown in figure)
is arranged for discharging water after dehydration. During
washing, the clothes 5 are placed in the inner tub 2.
[0040] On the wall of the inner tub 2, a washing medium layer 3 is
arranged, which may be made from ceramic or polymer materials etc.
Polymer is preferably used as the washing medium in the embodiment.
The polymer is selected from the group consisting of PP, PE, PS,
PVC, or EVA etc., or the mixture of the aforesaid materials, which
comprises hydrophilic and hydrophobic components as well as a
surfactant component, with a relatively strong capacity of
adsorbing the dirt. The polymer medium layer 3 may be arranged on
the inner surface and/or the outer surface of the wall of the inner
tub 2, so as to increase the adsorbing area and improve the
adsorbing capacity of the medium layer 3. In addition to arranging
the medium layer 3 on the wall of the inner tub 2, the medium layer
3 may also be arranged on the wall of the outer tub 1 for further
increasing the adsorbing area and adsorbing capacity of the medium
layer 3. Based on comprehensive considerations about cost,
manufacturing process and the total weight of the machine etc.,
preferably it is recommended to only arrange one medium layer 3 on
the inner surface of the wall of the inner tub 2. If the medium
layer 3 is arranged on other positions, the structure similar to
the followings may be adopted.
Embodiment 1
[0041] In the embodiment, the medium layer 3 may be coated on the
inner surface of the inner tub 2 via coating technique, or fixedly
installed on the wall of the inner tub 2 by fasteners, such as
screw. As same with the inner tub 2, the medium layer 3 is provided
with a plurality of through-holes (not shown in figure) with round,
rectangle or polygon etc. in shape, as the same as the shape of the
first opening hole 4 shown in FIG. 2, for the washing water flowing
through. The water flows in the tub via the through-holes during
washing; the washing water is discharged into the outer tub 1 when
dehydration, and finally the water is discharged from the water
outlet at the bottom of the outer tub 1. If the medium layer 3 is
arranged on the wall of the outer tub 1, the medium layer 3 is not
arranged with the through-holes for the water flowing through.
[0042] The medium layer 3 may be coated or installed on the overall
wall of the inner tub 2, or coated or installed on a part of the
wall of the inner tub 2. The former structure has a better
adsorbing capacity and is favorable to the rotary balance of the
inner tub 2. During washing, the medium layer 3 adsorbs the dirt in
washing water from the clothes 5 to the utmost through contacting
with the washing water contiguously. Thus during washing, the
washing water keeps a certain cleanliness, and the clothes 5
directly contact with the medium layer 3 contiguously so as to let
the medium layer 3 directly adsorb the dirt on the clothes 5.
Therefore, a small amount of water is enough, which can achieve the
purpose of saving water.
[0043] The structure of the medium layer 3 may be provided with a
smooth surface for expanding the contact area between the medium
layer 3 and the washing water and improving the capacity of
adsorbing the dirt. As shown in FIG. 1, the surface of the medium
layer 3 is provided with a plurality of humps 6 which may be
arranged continuously or dispersedly.
[0044] To increase the contact area between the medium layer 3 and
the washing water, the medium layer 3 may be provided with a porous
structure on the polymer surface. The holes on the surface are
disconnected with and separated from each other, so as to drain the
stored water inside the hole and improve the regeneration capacity
of the medium layer 3. The diameter of hole is preferred 0.01-0.1
mm.
[0045] In a roller washing machine, the inner tub 2 needs to be
arranged with at least one lifting block 7 that is protruding
inward. During washing, driven by the lifting block 7, the clothes
5 are lifted up and down in the inner tub 2 continually in circles
to reach the washing effect. The number of the lifting blocks 7 may
be 1-3, preferably three lifting blocks 7 are arranged along the
circumference of the inner tub 2 uniformly. The medium layer 3 and
the lifting blocks 7 are staggered, or the medium layer 3 is spread
on the whole inner wall of the inner tub 2 while the lifting blocks
7 are fixed on the medium layer 3.
[0046] The following further describes the washing method of the
aforesaid washing machine in combination with FIG. 1.
[0047] Taking a roller washing machine as an example, the washing
method comprises the following steps:
[0048] Step 1: like a normal roller washing machine, putting the
clothes 5 to be washed into the inner tub 2, in the meantime,
opening the water inlet on the upper side of the outer tub 1, via
which the water flows in the outer tub 1; the washing water mixing
with the detergent flows into the outer tub 2; and then the water
flows through the first opening hole 4 on the inner tub 2 and the
through-holes on the medium layer 3 to be fully mixed with the
clothes 5 to be washed. In this process, only an appropriate amount
of water and detergent is needed, to ensure the clothes 5 to be
soaked in the water.
[0049] When the washing water inpour and soak the clothes 5, the
clothes 5 to be washed need to be soaked for a certain time so as
to fully soak the clothes 5 in the washing water and further
improve the cleaning effect.
[0050] Step 2: the inner tub 2 is driven to rotate and then the
medium layer 3 rotates correspondingly; driven by the lifting block
7, the clothes 5 are lifted up and down in the tub in circles;
during washing, the dirt on the clothes 5 is removed by the washing
water and then the washing water with the dirt scours the medium
layer 3 continually; during continually contacting with the washing
water, the medium layer 3 adsorbs the dirt in the washing water.
Furthermore, during washing, the clothes 5 may also directly
contact with the medium layer 3 continually, via which the dirt on
the clothes 5 is directly adsorbed, so as to achieve the purpose of
cleaning the clothes 5.
[0051] As for a pulsator washing machine, during washing, the
pulsator rotates clockwise and anticlockwise alternately to form a
rotating water flow inside the tub by driving the rotation of the
pulsator. The dirt on the clothes 5 is removed by the washing water
and the washing water with the dirt scours the medium layer 3
continually; during continually contacting with the washing water,
the medium layer 3 adsorbs the dirt in the washing water.
Furthermore, during washing, the clothes 5 may also directly
contact with the medium layer 3 continually, via which the dirt on
the clothes 5 is directly adsorbed, so as to achieve the purpose of
cleaning the clothes 5.
[0052] Step 3: the inner tub 2 is driven to rotate at a high speed,
and the medium layer 3 also correspondingly rotates rapidly; the
clothes 5 and the medium layer 3 are dehydrated in the meantime,
and then the water is discharged from the water outlet at the
bottom of the outer tub 1. The dehydration process of the medium
layer 3 is also its self-cleaning process, which improves the
regeneration capacity and prolongs the service life of the medium
layer 3 to some extent.
[0053] Step 4: during rinsing process, adding appropriate clean
water into the tub, rinsing the clothes 5 according to the
aforesaid process, conducting dehydration after the rinsing, and
finally completing the entire washing process of the clothes 5.
[0054] After the dehydration of the clothes 5 and the medium layer
3, utilizing a heat pump device or heating pipe to blow hot wind
into the inner tub 2 for drying the clothes 5 and the medium layer
3. Thus may also further prolong the service life of the medium
layer 3 and be helpful to ensure the dryness inside the tub and
reduce mildew breeding because of the dampness inside the tub.
Embodiment 2
[0055] In an old-fashioned double cylinder washing machine, the
washing tub for washing is of single-tub structure, in which a
rotating water flow is formed by the pulsator rotating clockwise
and anticlockwise alternately during washing. The dirt on the
clothes 5 is removed by the washing water. In this washing machine,
a polymer washing medium layer 3, which is not arranged with
through-holes for the water flowing through, may be coated on the
inner surface and/or the outer surface of the wall of the washing
tub. The structure of the medium layer 3 is as the same as that in
Embodiment 1, so it is not described additionally hereby.
[0056] In this washing machine, on account of that the dehydration
of the clothes 5 being accomplished in another spin dryer tub,
therefore, the medium layer 3 has no the process of dehydration.
The method of adding hot wind in the tub may be adopted.
Embodiment 3
[0057] As shown in FIG. 3, the difference from the Embodiment 1 is
that, the medium layer 3 arranged on the inner surface of the inner
tub 2 is an interlayer containing solid polymer particles 8 in the
middle and being fixed on the wall of the inner tub 2 An interlayer
wall 9 is arranged with through-holes (not shown in figure) for the
washing water flowing through. The medium layer 3 is fixed on the
wall of the inner tub 2 by the fasteners, such as screw, to ensure
that the medium layer 3 rotates with the inner tub 2.
[0058] To avoid the particles 8 leaking out of the inner tub 2 and
the medium layer 3, the diameter of the first opening hole 4 on the
inner tub 2 and the through-holes on the medium layer 3 are less
than the minimum diameter of the particles 8. The diameter of the
particles 8 is generally 2-4 mm; therefore, the diameter of the
first opening hole 4 and the through-holes are less than 2 mm.
Preferably the diameter of the first opening hole 4 and the
through-holes is 1-1.5 mm. Thus can not only ensure the washing
water to flow in or out successfully, but also avoid the leakage of
the particles 8.
[0059] To increase the adsorbing capacity of the medium layer 3, in
addition to the solid polymer particles 8 containing adsorbing
capacity, the interlayer wall 9 is also made from polymer material.
The interlayer wall 9 is also with adsorbing capacity as same as
that in Embodiment 1. The surface of the interlayer wall 9 may be
smooth. In order to increase the contact area between the
interlayer wall 9 and the washing water and enhance the capacity of
adsorbing the dirt, the surface of the interlayer wall 9 is
provided with a plurality of humps 6 which may be arranged
continuously or dispersedly, as the same as the one in Embodiment
1. For increasing the contact area between the interlayer wall 9
and the washing water, the surface of the interlayer wall 9 may be
provided with porous structure on the polymer surface. The holes on
the surface are disconnected with and separated from each other, so
as to drain the stored water inside the hole and improve the
regeneration capacity of the interlayer wall 9. The diameter of the
hole is preferably 0.01-0.1 mm.
[0060] Similarly, to order to improve the adsorbing capacity of the
particles 8, the particles 8 are of porous structure on the
surface. The holes on the surface are disconnected with and
separated from each other, so as to drain the stored water inside
the hole and improve the regeneration capacity of the medium layer
3. The diameter of the hole is preferably 0.01-0.1 mm.
[0061] The interlayer of the medium layer 3 is spread on the whole
wall of the inner tub 2. The middle space of the interlayer is
completely through. The interlayer wall 9 equals to forming into a
second inner tub. During washing, the washing water which flows in
and out of the interlayer of the medium layer 3, contacts with the
interlayer wall 9 and the particles 8 in the interlayer in the mean
time. The dirt in the washing water from the clothes 5 is adsorbed
by the interlayer wall 9 and the particles 8 jointly. During
washing, the clothes 5 directly contact with the interlayer wall 9
continually, via which the dirt on the clothes 5 is adsorbed, so as
to achieve the purpose of washing.
[0062] In the roller washing machine, the inner tub 2 is provided
with at least one lifting block 7 that is protruding inward and
fixed on the interlayer wall 9.
[0063] The following further describes the washing method of the
aforesaid washing machine in combination with FIG. 3.
[0064] Taking a roller washing machine as an example, the washing
method comprises the following steps:
[0065] Step 1: like a normal roller washing machine, putting the
clothes 5 to be washed into the inner tub 2, in the meantime,
opening the water inlet on the upper side of the outer tub 1, via
which the water flows in the outer tub 1; the washing water mixing
with the detergent flows into the outer tub 2; and then the water
flows through the first opening hole 4 on the inner tub 2 and the
through-holes on the interlayer wall 9 of the medium layer 3 to be
fully mixed with the clothes 5 to be washed. In this process, only
an appropriate amount of water and detergent is needed, to ensure
the clothes 5 to be soaked in the water.
[0066] When the washing water inpour and soak the clothes 5, the
clothes 5 to be washed need to be soaked for a certain time so as
to fully soak the clothes 5 in the washing water and further
improve the cleaning effect.
[0067] Step 2: the inner tub 2 is driven to rotate and then the
medium layer 3 rotates correspondingly; the clothes 5 are lifted up
and down in the tub in circles. During washing, the dirt on the
clothes 5 is removed by the washing water, and then the washing
water with the dirt scours the interlayer wall 9 continually, and
to enter the inside of the interlayer to contact with the particles
8. During continually contacting with the washing water, the
interlayer wall 9 and the particles 8 adsorb the dirt in the
washing water. Furthermore, during washing, the clothes 5 may also
directly contact with the interlayer wall 9 continually, via which
the dirt on the clothes 5 is directly adsorbed, so as to achieve
the purpose of cleaning towards the clothes 5.
[0068] As for a pulsator washing machine, during washing, the
pulsator rotates clockwise and anticlockwise alternately to form a
rotating water flow inside the tub by drive the rotation of the
pulsator. The dirt on the clothes 5 is removed by the washing
water. Then the washing water with the dirt scours the interlayer
wall 9 continually, and enters the inside of the interlayer to
contact with the particles 8 in the interlayer. During continually
contacting with the washing water, the interlayer wall 9 and the
particles 8 adsorb the dirt in the washing water. Furthermore,
during the washing, the clothes 5 may also directly contact with
the interlayer wall 9, via which the dirt on the clothes 5 is
directly adsorbed, so as to achieve the purpose of cleaning the
clothes 5.
[0069] Step 3: the inner tub 2 is driven to rotate at a high speed,
and the medium layer 3 also correspondingly rotates rapidly. The
clothes 5, the interlayer wall 9 and the particles 8 are dehydrated
in the meantime, and then the water is discharged from the water
outlet at the bottom of the outer tub. The dehydration process of
the medium layer 3 is also its self-cleaning process, which
improves the regeneration capacity and prolongs the service life of
the medium layer 3 to some extent.
[0070] Step 4: during rinsing process, adding appropriate clean
water into the tub, rinsing the clothes 5 according to the
aforesaid process, conducting dehydration after the rinsing, and
finally completing the entire washing process of the clothes 5.
[0071] After the dehydration of the clothes 5 and the medium layer
3, utilizing a heat pump device or heating pipe to blow hot wind
into the inner tub 2 for drying the clothes 5 and the medium layer
3. Thus may also further prolong the service life of the medium
layer 3 and be helpful to ensure the dryness inside the tub and
reduce mildew breeding because of the dampness inside the tub.
[0072] The structure of the medium layer 3 in the embodiment also
applies to a single-tub washing machine.
Embodiment 4
[0073] As shown in FIG. 4, the difference from Embodiment 3 is
that, the interlayer of the medium layer 3 is provided with a
plurality of chambers 10 separated from each other, so as to avoid
the uneven distribution of the particles 8 in the interlayer
influencing the adsorbing effect. The chambers 10 containing the
adsorbing particles 8 are separated by a division plate 11.
[0074] The structure of the medium layer 3 in the embodiment also
applies to a single-tub washing machine.
Embodiment 5
[0075] As shown in FIG. 5, the difference from Embodiment 3 is
that, the interlayer of the medium layer 3 includes a plurality of
chambers 10 separated from each other and the particles 8 are
contained in the chambers 10. Since the chambers 10 are separated
from each other, the chambers may be arranged on the wall of the
inner tub 2 discretely. The chambers 10 are arranged to stagger a
lifting block 7, and the lifting block 7 is directly fixed on the
wall of the inner tub 2.
[0076] In both a roller washing machine and a pulsator washing
machine, the chambers 10 are arranged along the axial direction
linearly or the radial direction annularly of the inner tub 2.
[0077] In a roller washing machine, when the chambers 10 are
arranged along the axial direction of the inner tub 2
discontinuously, the lifting block 7 is not arranged. The medium
layer 3 that is protruding towards the inner surface of the inner
tub 2 is used as the lifting block to lift the clothes 5 during
washing.
[0078] The structure of the medium layer 3 in the embodiment also
applies to a single-tub washing machine.
Embodiment 6
[0079] As shown in FIG. 6, the difference from Embodiment 5 is
that, the chambers 10 are fixed on the wall of the inner tub 2 in
the continuously corrugated form, which may further expand the
contact area between the medium layer 3 and the water, so as to
improve the adsorbing capacity of the medium layer 3.
[0080] In a roller washing machine, when the chambers 10 are
arranged along the axial direction of the inner tub 2
discontinuously, the lifting block 7 is not arranged. The medium
layer 3 that is protruding towards the inner surface of the inner
tub 2 is used as the lifting block to lift the clothes 5 during
washing.
[0081] The structure of the medium layer 3 in the embodiment also
applies to the single-tub washing machine.
Embodiment 7
[0082] The difference from the Embodiment 1 is that, in a roller
washing machine, the medium layer 3 may be coated on the lifting
block 7 of the inner tub 2 via coating technique, or fixed on the
lifting block 7 of the inner tub 2 by fasteners, such as screw. In
the structure, the medium layer 3 has no need to be provided with
through-holes for the water flowing through.
[0083] The structure in each aforesaid embodiment also applies to a
multi-tub washing machine. One, two or each of the washing tubs
thereof may be arranged with a medium layer 3.
[0084] As the foregoing, combining the disclosed solution content
of the attached drawings, similar technical solutions may be
derived. Without departing from the content of the technical
solution of the present invention, according to the technical
essence of the present invention, any simple amendment, equivalent
changes and modifications all fall within the scope of the
technical solution of the present invention.
