FIELD OF THE INVENTION
[0001] The invention relates to a washing machine and in particular to a washing machine
in which the laundry is washed inside an especially adapted flexible washing device
that is arranged in a fluid tight manner on the washing machine.
BACKGROUND OF THE INVENTION
[0002] Stain removal of laundry is often a trouble-some task, and some stains cannot easily
be removed in a conventional washing machine of today. Therefore, typically, some
kind of pre-treatment for stain-removal of the laundry before washing of the same
in the washing machine is often required.
[0003] As an example, a pre-treatment of the laundry's fabric with a so-called "stain remover"
is required. As another example, pre-treatment with soaking the laundry in water is
required alone or in addition to using the stain-remover.
[0004] Some stain removers may typically bleach the fabric. A typical example is chlorine
bleach, which is not safe for the fabric and hazardous to the environment.
[0005] Thus, stain-removal in addition to being time-consuming, is often not safe for the
fabric or hazardous to the environment
[0006] Today, there are known sensor controlled washing machines for stain removal. Complicated
and expensive sensor technology controls the washing machine such that more (stain
removal) or dirty laundry or less intense (no stain removal) washing is provided.
Typically, the rotating drum's movement is controlled. Typically, the whole laundry
is washed, not just a stained part thereof. This may cause unnecessary wear to the
laundry not requiring stain removal.
[0007] Based on the above knowledge and related problems, it is a need to find a solution
to the problems with stain-removal.
[0008] A conventional washing machine washes laundry, such as clothes, by wetting them,
de-moisturizing them, wetting them again etc. until the laundry is clean. In order
to accomplish this laundering conventional washing machines typically comprise a cylindrical
drum in which the laundry may be alternately soaked and dried without having to be
transferred between different chambers.
[0009] A less conventional washing machine without a conventional cylindrical drum is described
in
EP-B1-2633 113.
SUMMARY OF THE INVENTION
[0010] An object of the invention is to provide a washing machine without a conventional
cylindrical drum that washes also stained laundry in a satisfying manner without the
use of pre-treatment for stain-removal.
[0011] The invention relates to a washing machine as defined by claim 1.
[0012] WO 2017/138872 describes a washing machine for the washing of laundry such as clothes and textiles.
The washing machine contains a housing, wherein the housing comprises: an inlet for
supplying washing water, an outlet for disposal of washing water, a pump for pumping
the washing water. The housing contains one, or a plurality of washing drawers. Here,
each washing drawer has a pair of conduits for fluid tight connection of a respective
flexible washing compartment for washing laundry and arranged in the washing drawer.
Each drawer of the housing is further arranged to lead water from the inlet of the
housing via conduit to the respective washing compartment arranged therein and, by
means of the pump and conduit, to pump air and water out from the respective flexible
washing compartment in order to create a pressure difference inside the washing compartment
with respect to the surrounding pressure and by that emptying the flexible washing
compartment of washing water.
[0013] US 6,219,871 shows an automatic laundry washing machine that is suitable for use in living units
having no area set aside for laundry facilities is achieved by replacing the heavy
bulky parts of the currently popular automatic washing machine design with a light
flexible bag. A large portion of the volume of any washing machine is the vessel for
containing the laundry solution and articles to be washed. That vessel is a flexible
bag made of modern durable material so as to be collapsible both while in use and
for storage. The method of use includes the complete process of washing, rinsing,
and extracting excess water in an automatic cycle analogous to standard automatic
washing machines popular today. The vessel containing the items being laundered is
a waterproof laundry bag with automatic washing apparatus attached. Items are automatically
washed in that bag. The automatic process includes cycles of filling, washing, rinsing
and extracting such that the clothes are ready for a drying process such as hanging
out to dry or putting into a tumble dryer. The agitating of the washing and rinsing
cycles is accomplished without the familiar bulky agitator thereby reducing the volume
requirements and the traditional wear and tear on the garments. By eliminating the
bulky agitator and the spin water extraction method, the heavy transmission is also
eliminated. The water extraction cycle is done in a much less violent way than the
conventional spin cycle by allowing atmospheric pressure to collapse the washing vessel
and press the water from the articles as the water and air are pumped from the vessel
in the draining portion of the cycle. The cleaning ability of the water is enhanced
by built in ionic processing of the water thereby reducing the required amount of
laundry detergent. The agitating in the non-electrically conductive vessel generates
static electric charges in the process and ions thus produced further enhance the
cleaning ability of the water. Cavitation produced in a multi-frequency washing action
further enhances the washing ability of the water. The washing machine is light, compact
and collapsible and is as portable as a piece of luggage.
[0014] A washing detergent may be provided directly to the washing compartment or via a
separate compartment in the washing machine to be distributed into the washing compartment
together with the water. After that the water has been added to the washing compartment
the pump is activated.
[0015] Firstly the pump is used to suck air from the washing compartment to reduce the volume
of the washing compartment, whereby the laundry is compressed and soaked in water.
Gradually the water is sucked out, and the same water may be returned for instance
via a filter to a reservoir provided in the washing machine to the washing compartment
a couple of times before the water is exchanged and the cycle is repeated once again.
[0016] Specifically, the invention relates to a washing machine for the washing of laundry
such as fabric, clothes and textiles. The washing machine has means, in particular
zones, for stain-removal. An advantage of the at least one stain-removal zone having
increased flow of water is that no time-consuming and/or hazardous pre-treatment will
be required before washing in the washing machine. Washing is hence increased locally
in each stain removal zone.
[0017] An advantage compared to conventional washing machines is that the whole content
of the laundry must be washed even if only part of the content of the laundry is stained.
This is because one does not know where in relation to the rotating drum the stains
are located. In the inventive washing machine, the laundry is always on the same location
but only the water is flowing (moving). This implies that the satins are located in
particular local areas and by preparing these local areas having a higher flow of
water, higher degree of detergent or other extra treatment, it is possible to optimize
the washing such that only parts of the laundry is subject to extra treatment, whereas
the other parts of the content of the laundry is subject to a gentle treatment. This
implies less wear, less micro-fiber, less use chemicals, and less energy required.
[0018] According to one embodiment the increased flow of water is arranged to be continuously
through-flowing through the at least one stain removal zone.
[0019] According to another embodiment the increased flow of water is oscillating.
[0020] Typically the stain removal zones are arranged in a set of stain removal zones. A
particular set is then typically adapted for a particular washing compartment.
[0021] An advantage is that a several different type of laundry can be washed at the same
time in the different washing compartments; also having a plurality of different sets
of stain-removal zones in case of a plurality of drawers. In this way,
[0022] Further advantages of the invention will be apparent from the detailed description
and the dependent claims.

DETAILED DESCRIPTION OF EMBODIMENTS
[0024] A first embodiment of the washing machine according the invention is shown in FIG.
1a. In this figure, the components of the washing machine are only schematically shown,
but will be shown in more detail in FIGS. 2-3. The washing machine 1 is suitable for
the washing of several types of laundry such as clothes and textiles at the same time
or in any desired manner. In such an embodiment it is suitable that the user has several
sets of stain removal zones, e.g. one first set for one type of laundry such as a
pair of trousers having one type of stain removal zones Z for instance at knees and
pockets etc., one second set for shirts having another type of stain removal zones
Z, such as at arm-ends, neck etc.
[0025] FIG. 1a shows, in a perspective view, an embodiment of a washing machine comprising
a housing with a plurality of washing drawers, FIG. 1b shows yet an alternative embodiment
of a washing machine having a plurality of drawers arranged side-by-side, and FIG.
1c shows an alternative embodiment of a washing machine comprising one drawer combined
with a conventional washing machine having a perforated metal washing drum, The housing
may alternatively be embodied as an frame in all embodiments without departing from
the invention.
[0026] Now is referred to Fig. 1a.
[0027] The washing machine shown in Fig. 1a comprises a housing 1a. The housing 1a comprises
a plurality of drawers 2 provided as a set of washing drawers 2 stacked onto each
other in the housing 1a, each drawer 2 comprising a respective flexible washing compartment
10 having one or more stain removal zone(s) Z (schematically shown in the most upper
drawer), such as an essentially flat washing compartment 10 having a zipper, or other
water and air-tight closable seal, or comprising a pair of flexible membranes (not
shown in Fig. 1a), for washing laundry and arranged in the washing drawer 2 such that
the one or more stain-removal zones) is/are located properly and adapted to locally
treat stained areas of the laundry.
[0028] Alternatively, a hard openable frame having a water- and/or air-tight seal can be
provided instead of the zipper.
[0029] The washing machine 1 comprises an inlet 4, for supplying clean washing water and
an outlet 5, for disposal of used washing water. The washing machine 1 further comprises
one or more pump(s) 6, in order to pump the used washing water out of the washing
compartment. In order to supply clean water via the inlet 4 no pump is normally needed
because the water will be provided from a pressurized and closed water system such
as a public water supply system. Each washing compartment 10 in each drawer 2 is connected
to a pair of conduits 4a, 5a arranged to lead water from the inlet 4 of via a conduit
4a to the respective washing compartment 10 arranged in each drawer 2 and to lead
air and water away from the washing compartment 10 via a conduit 5a, by means of the
pump 6. The pair of conduits 4a, 5a from each washing compartment 10 in each drawer
2 can be combined into one inlet 4 and outlet 5 for all washing compartments 10. The
conduit 5a may also be connected to a reservoir 7 (schematically shown) inside the
washing machine 1 for receiving used washing water and recirculating the washing water
one or more times back to the washing compartment 10.
[0030] The pump 6 is utilized to create a pressure difference between the washing compartment
10 and its surroundings (in the drawer 2), typically a negative pressure, normally
referred to as vacuum in the washing compartment 10 and atmospheric pressure in the
drawer 2.
[0031] According to another embodiment, it is alternatively possible to arrange the washing
compartments 10 side-by-side as shown in FIG. 1b.
[0032] Alternatively, to the embodiment shown in Fig. 1a, which comprises a plurality of
drawers, it is possible to just have one drawer 2, potentially in combination with
a conventional washing machine as shown in Fig. 1c, but not limited thereto. Alternative
embodiments, combinations of one or more drawer(s) 2 with a conventional washing machine
having a perforated metal washing drum at any side of the conventional washing machine
are also possible without departing from the invention. A side-by-side combination
may be an advantage for instance for washing shirts hanging.
[0033] Now is referred to Fig. 2a, which in a view from above shows a flexible washing compartment
10 embodied as a flexible bag having a openable and closable seal 13, or is alternatively
arranged in an openable/closable air and water-tight frame (not shown), for opening
and closing the washing compartment 10. The flexible washing compartment 10 may be
made of any fluid-tight suitable material such as plastics and may be transparent
such that a user easily can see if the washing compartment is empty or not. In Fig.
2a, the washing compartment 10 is a flat transparent bag, shown filled with laundry
11, herein exemplified as a pair of trousers arranged in a flat manner in the flexible
washing compartment 10. According to aspect, but not limited thereto, the laundry
11 is wetted in a longitudinal direction (schematically shown) when the pump is turned
on.
[0034] It is an advantage that the laundry 11 can be arranged flat in that ironing can be
avoided and some sensitive laundry may benefit from being washed flatly and without
the laundry moving inside the washing compartment 10, thereby avoiding wearing of
the laundry 11 against the walls of the washing compartment 10 as is typically the
case in a conventional washing machine having a rotation perforated metal drum inside
which the laundry wears against the drum. Stain removal in such a conventional washing
machine implies that the whole laundry 11 is always washed, even no-stained parts.
This provides unnecessary wear also to non-stained parts (not in stain removal zones
Z not requiring increased flow of water.
[0035] The washing compartment 10 is connected to a pair of conduits 4a, 5a, which are schematically
shown only. Typically, the washing compartment 10 is permanently fixed into the drawer
2 and permanently connected to the conduits 4a, 5a.
[0036] Now is also in addition to FIG. 2a referred to FIG. 2b.
[0037] FIG. 2b shows in a perspective view from the side, a flat flexible washing compartment
10 filled with a particular type of laundry 11, herein a pair of trousers,
[0038] A means 12 for providing a set of stain removal zones Z is provided on the laundry
11. The means 12 is a solid flat screen member for instance made of plastics having
through going holes providing the stain removal zones Z through which an increased
flow of water can flow when the pump 6 is turned on. The screen member 12 may vary/look
different providing a particular set of stain removal zones for particular laundry
11. The open stain removal zones Z provides increased flow of water through the laundry
11 and thereby removes stains locally and efficiently in particular areas of the 11
without negatively also washing other parts of the laundry not requiring stain-removal.
This is schematically marked as in this Fig. 2a. This embodiment is suitable for removing
stains from particular areas of the laundry 11 such as on the knees on a pair of trousers
(or other parts of the laundry 11 known to be more stained than other parts known
to be less stained. An advantage with the inventive solution is that it is simple
and easy compared to today's known complicated and expensive sensor solutions.
[0039] FIG. 2d shows, in a sectional view taken along line A-A in FIG. 2b, a set 12 of stain
removal zones Z having increased flow of water, wherein water is oscillating (shown
schematically by double-headed arrows), flowing through the stain removal zones Z.
[0040] FIG. 2c shows, in a sectional view taken along line A-A in FIG.2b, a set 12 of stain
removal zones Z having increased flow of water, wherein the water is continuously
through-flowing through the stain removal zones Z.
[0041] Now is referred to Fig. 3, which shows, in a perspective view, a washing drawer 2
having a pair of conduits 4a, 5a 4a,5a for fluid tight connection of a respective
flexible washing compartment 10 for washing stained laundry and being arranged in
the washing drawer 2. The washing compartment 10 having stain removal zones Z shown
in this drawing comprise of two flexible membranes, herein an upper 10a, and a lower
membrane (not shown), which washing compartment 10 can be opened or closed in a fluid-tight
manner by moving the drawer 2 out from the housing 1a for opening, or into the housing
1a for closing the washing compartment 10. This can be achieved since, the membranes
are mounted in a respective upper 10aa, and lower 10bb frame, of which the upper membrane
10a can be moved, opened or closed. According to various embodiments, the washing
compartment 10 may alternatively comprise one or more membranes, such as one flexible
membrane provided on a rigid plate. The upper frame having the upper membrane 10a
is arranged to be automatically opened when the drawer 2 is pulled out. This can be
provided by having the frames 10aa, 10bb provided at a rail, wherein a pressure roll
is arranged to press the upper frame 10aa having the upper membrane 10a against the
lower frame 10bb having the lower membrane against each other when the drawer is pushed
in and releasing the frames 10aa, 10bb to each other when the drawer is pulled out.
Other mechanisms such as parallelograms, excenters, tracs, manual doors etc. providing
opening or closing the washing compartment are obvious for the skilled person and
the invention is by no means limited to this particular embodiment.
[0042] Fig. 3 shows the washing compartment 10 made of membranes and containing laundry
and comprising two membranes 10a, 10b.
[0043] An alternative embodiment of the flexible washing compartment 10 can be made up of
two flexible membranes 10a, 10b is shown with laundry 11 inside. The two membranes
10a, 10b are arranged on a frame preventing the washing compartment 10 to restrict
across and along the frame, but still providing flat compression due to the pressure
difference between the pressure inside the flexible compartment 10 and its surroundings
in the drawer 2, typically the pressure inside the flexible compartment is negative
pressure and the pressure outside the flexible compartment is atmospheric pressure
or positive pressure providing a pressure difference.
[0044] The washing machine may also include an additional drying unit in order to dry the
laundry by the supply of dry hot air in the flexible washing compartment 10.
[0045] The washing machine 1 can operate as follows.
[0046] One or more of the flexible washing compartments 10 are opened and filled with laundry
11. Subsequently, water is provided via the inlet 4, and/or the conduit 4a to the
flexible washing compartment(s) 10. The water is heated to a desired temp. The heating
can be provided by means of a conventional heater (not shown) arranged inside or outside
the washing machine 1. Then the air is sucked out of the flexible washing compartment,
followed by the water being sucked out.
[0047] A washing detergent may be provided directly into the washing compartment or via
a separate washing detergent compartment 2a provided centrally in the washing machine
1 or in the specific drawer 2 to be distributed into the washing compartment 10 together
with the water. After that the water has been provided to the washing compartment,
the pump 6 is activated. Firstly the pump 6 is used to suck air from the washing compartment,
to minimize the volume that has to be wetted, whereby the laundry is compressed and
soaked in water (See Fig. 2a, where the wetting of the pair of trousers inside a washing
compartment 10 having a zipper 13 is indicated schematically by the marking "wetting").
Gradually the water is sucked out, and the same water may be returned for instance
via the reservoir 7 and filter(s) provided in the washing machine to the washing compartment
a couple of times before the water is exchanged and the cycle is repeated once again.
[0048] An example of the operation of the invention according to various embodiments will
now be given. First, the laundry 11 is placed in a washing compartment 10 of any of
the types described above and in a drawer 2 of the washing machine 1. In the shown
embodiment, the laundry 11 is placed in the washing compartment 10 inside the drawer
2. Then the washing compartment 10 is closed. After these measures, first air is sucked
out, creating vacuum or under pressure in the fibers and/or textiles of the laundry
11 then, clean washing water is supplied via inlet 4 to the washing compartment 10
replacing the under pressure, or vacuum and normalizing pressure and any air remaining
in the washing compartment 10 is pumped out via the pump 6 such that the laundry 11
is soaked and compressed by the walls of the washing compartment 10. Once the laundry
11 is soaked it is possible to pump out the washing water from the washing compartment
via the pump 6, wherein a certain negative pressure again is created in the washing
compartment, and wherein the laundry 11 is further compressed by the atmospheric pressure
(or alternatively positive over-pressure) outside the bag. The washing becomes efficient
thanks to the combination of pressure towards the laundry and the movement of the
washing water and air bubbles, which penetrate in between the fibers of the laundry
and deeply remove impurities. Pressure differences acting on air bubbles influences
the air bubbles to change in size, which implies that the air-bubbles on a micro-level
"pump" the water back and forth inside the fibers. Air is elastic contrary to water,
such that water is transferred when the air bubbles grow or shrink. If a micro-bubble
is stuck inside a hollow fiber, the fiber will pump clean inside the fiber. At the
lowest pressure, the air bubbles are as large as possible. Further, the laundry may
be kneaded by the walls of the washing compartment which increases the washing efficiency.
Once the washing water has been re-circulated via filter a number of times, the water
sucked out to the desired degree, the rinsing water is supplied to the washing compartment.
The purpose of the rinsing water is e.g. to perform a final cleaning of the laundry
and to remove any remainders of the washing detergent. Further, rinsing fluid and/
or fabric softener, which softens and/ or gives the laundry a pleasant fragrance,
may be supplied together with the rinsing water. The rinsing water is removed from
the washing machine in the same manner as the washing water. Hence, any air that is
left in the bag is pumped out such that the laundry is compressed and soaked, and
subsequently the rinsing water is pumped out from the washing compartment, wherein
a certain negative pressure is created in the washing compartment, and wherein the
laundry is compressed by the atmospheric pressure outside of the washing compartment.
Preferably, electronic equipment of the washing machine comprises a control with which
it is possible to control the dryness of the laundry. The dryness may also be one
of the parameters that are controlled by means of different washing programs, such
that every washing program is connected to a certain dryness, which naturally also
may be the same for several different washing programs. Before the washing compartment
is opened air should be let in, in order to facilitate the opening of the bag.
[0049] Preferably, the washing machine 1 also comprises a heater unit with which the inlet
water in inlet 4 may be heated to the desired temperature regardless of the inlet
temperature.
[0050] The washing machine 1 could also include a small tank in which the heating unit may
be arranged. The tank makes it possible to re-utilize the washing water. Due to environmental
friendly reasons it is advantageous that the laundry is washed several times with
the same water, because it saves both water and heating energy. Further, the washing
efficiency is not drastically worsened because the same washing water can be used
several times, since the washing water very rarely is saturated in impurities. Hence,
a prewash with a first water change is only necessary when very dirty laundry is to
be washed. A water exchange should however always be made for the rinsing of the laundry.
[0051] Parts of the inner walls of the washing compartment can be provided with fluid leading
means such as concavities- and/or convexities in order for the walls not to get stuck
towards each other without letting water and air pass when a negative pressure of
a certain magnitude has been created inside the washing compartment.
[0052] By creating islands of fluid leading surfaces surrounded by areas preventing fluid
motion, the maximum flow of water through the laundry can be achieved. The washing
effect is on the contrary achieved when the fluid flows through the laundry, preferably
at the same time as they are kneaded by the walls as they are being sucked towards
each other.
