Abstract:
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. The set up procedure is simple and no assembly is required beyond attaching a quick connect fastener to a water faucet and plugging in a power cord. The washing machine is light and takes little storage space. It can be put in a small closet or on a shelf when not in use. The minimum capacity of the washing machine is a single garment. The normal capacity of the washing machine is comparable to that of a standard household washing machine.

Description:
BACKGROUND—FIELD OF THE INVENTION 
     This invention relates to washing clothes in the home, particularly to an automatic washing machine which operates in a seemingly paradoxical manner and which will automatically wash a full sized load in the home without a requirement for space dedicated to a laundry facility in the home and which, while drastically reducing the size and weight from that of a standard automatic washing machine, increases cleaning efficiency and reduces environmental pollution to a greater extent than heretofore possible. 
     BACKGROUND—DESCRIPTION OF THE PRIOR ART 
     Ever since modern machines moved washday activities inside, there has been a long recognized and unfilled need to eliminate the requirement for a dedicated laundry room in living units while still having the capability to wash clothes without making an outside trip and without having to do it by hand. 
     Another long recognized and unfilled need is the lack of laundry facilities in a living unit such as an apartment or mobile home which does not have a designated laundry area set aside and dedicated to full time occupancy by laundry machines. This need has been recognized as is evidenced by many inventions of compact or portable machines. However, these inventions have such a greatly reduced capacity or increased inconvenience that it has not been commercially accepted as a solution to this problem. Thus, the commercial success of the local Laundromat. 
     Keeping clothes clean has been a problem since ancient times. Early in the history of this country pioneers washed their clothes by dipping them in the water of the river and rubbing them on rocks near the water. However, a trip outside the home to the local laundry facility was required. 
     The forerunner of the modern washing machine was a washboard. Using the washboard was somewhat like washing in the river. The user dipped the clothes in a tub of water and rubbed the clothes on the washboard. No longer was a trip to the river necessary. However, the drudgery and dedication of time remained. 
     The next major break through was the self powered washing machine eliminating the backbreaking work of rubbing the clothes by hand. However, added to the drudgery and dedication of time was the requirement for dedicated space in the home for the washing machine. Suddenly, the useful space in the home became less. The washing machine was always there and in the way. 
     After that came the automatic washing machine which eliminated the drudgery and the requirement of getting hands wet. However, the dedicated space requirement taking living space from the home remained a problem. 
     Not all homes have the luxury of extra space to dedicate to a washing machine. Even still, the residents of many homes that have no laundry facilities make the periodic outside trip to the public Laundromat. Still remaining is that long recognized and unfilled need, the need for full sized automatic laundry capability in the home without the requirement of space dedicated to laundry machines. 
     When people used the river for a Laundromat, wringing out the water was simply a matter of manually applying twisting pressure with the hands. However, that was manual labor. 
     With the early washing machine came the powered wringer, a device with rollers pressed against the clothes to squeeze the water from the clothes. However, still a human was required to feed each piece into the rollers, sometimes with much pain when long hair would get in with the clothes. 
     Automatic washing machines came with the advent of water extraction by centrifugal force in a spinning tub. No longer was it necessary to manually remove the clothes from the tub to remove the water from the clothes. The clothes rather than the water remained in the tub throughout the automatic cycle with the water coming and going in the same tub. The disadvantage of the centrifugal extraction machine is the requirement for a perforated washing and spinning tub inside a water containing tub. This results in two heavy metal tubs in addition to the heavy enclosure made of rigid metal surrounding all the other parts results in a big heavy machine that requires a permanent location. With the advent of centrifugal extraction the rollers were removed from the legs of the washing machine. Homemakers have been sharing their homes with the washing machine ever since. Other wringing methods were tried, but did not become popular. This loss of living space in the home has been the standard for decades. 
     Further, most clothes washing machines are inefficient energy wasters and environment polluters that wash the laundry by utilizing the mechanical force of an agitator and the surface active force of a chemical detergent. Accordingly, in order to improve the washing efficiency, many clothes washing machine makers have utilized various methods including such as improving the agitators ability to agitate the laundry, extending the operating time of the motor during a washing and/or rinsing time period and improving the quality and/or increasing the quantity of detergent used in the washing machine. However, there are limits to improvements in the washing efficiency by the aforementioned methods for the following reasons: 
     (a) The methods utilizing increased mechanical force to improve the washing efficiency may cause damage to the laundry or to efficiency of the clothes washing machine. 
     (b) In methods utilizing increased amounts of detergent, a relatively large amount of the detergent which does not react with the laundry is then discharged where it can later cause environmental pollution, and also the remaining detergent sticks to the laundry and thus the laundry is not effectively cleaned. 
     (c) Also, it is well known that if more than the recommended amount of detergent is used in the clothes washing machine, the washing efficiency of the washing machine is reduced. 
     Accordingly, inventors created several types of devices to generate surface tension reducing ions for the purpose of reducing the amount of detergent required: 
     U.S. Pat. No. 5,309,739 to Lee (1994) discloses a device which utilizes the generation of surface-tension-reducing hydroxyl ions for the purpose of reducing the amount of detergent required. However, this device is an add on to the standard automatic washing machine described above. 
     U.S. Pat. No. 4,066,393 to Morey and Dooley (1978) discloses a device which utilizes a cation exchange resin device to remove calcium and/or magnesium ions from the water for the purpose of reducing the amount of detergent required. However, this device requires a manual step in the washing process and it too is an add on to the standard automatic washing machine described above. 
     U.S. Pat. No. 5,358,617 to Ibbott (1994) discloses a water treatment devise to use in a standard automatic washing machine which utilizes electrically isolated electrodes of different electrochemical potential to ionize the wash water inside the washing machine for the purpose of reducing the amount of detergent required to little or none depending upon the amount of dissolved solids in the wash water. However, this device requires a standard automatic washing machine described above. 
     U.S. Pat. No. 2,997,870 to Serra (1961) discloses a washing machine which utilizes friction due to the motion of air, water, and an India rubber vessel in an electrostatic ionic process for the purpose of reducing the amount of detergent required. However, this washing machine is not automatic. It is an attempt to solve the problem of storage out of the way when not in use and has traded off the automatic feature for a more manual system with reduced capacity. 
     In the prior art there are many patents on collapsible, foldable, portable washing machines with an object to satisfy that long recognized and unfilled need to eliminate the requirement for a dedicated laundry room in living units: 
     U.S. Patent No. 4,305,265 to Burgas (1981) discloses a washing machine that is to be disassembled when not in use. However, it is not automatic, but hand powered, and complicated to set up. 
     Other examples of washing machine patents that purport to be space saving are too numerous to mention. Generally they suffer with some or all of the disadvantages of reduced capacity, manually powered, non-automatic, complicated, or inefficient. As a general rule, to make a washing machine lighter, collapsible, foldable, or portable, there is a trade off resulting in inefficiency, and reduced capacity. 
     The popular automatic washing machines of today are in the way all the time even when not used: 
     (a) They cannot be stored out of the way. 
     (b) They cannot be folded into a small space 
     (c) They cannot be moved or carried around easily. 
     (d) They are not easily transportable. 
     The popular automatic washing machines of today contribute significantly to environmental pollution and waste: 
     (a) Excess, inefficient detergent use contributes to chemical pollution. 
     (b) Excess energy use wastes our natural resources. 
     (c) Excess noise disrupts our daily life. 
     (d) Mechanical agitator causes excess wear and tear on clothing.

     SUMMARY OF THE INVENTION 
     In accordance with the present invention, an automatic washing machine comprises a container, at least partially constructed in the form of a flexible bag, a filling device, an agitating device, an extracting device, and a controlling device. Alternate embodiments further optionally comprise one or more of the features described in the following “Features of Invention.” 
     Features of Invention 
     It may be helpful to the understanding of our automatic washing machine to categorize many of the features. Also included in this list are many features which have been gleaned from the prior art and are listed here as being examples of optional features that would be obvious to one versed in the art and for that reason are not included in the figures. 
     General Features 
     A feature of our automatic washing machine is a revolutionary new design based on the use of a flexible container, herein described as a flexible bag, which eliminates many heavy metal parts vital to the design of prior art machines. This elimination of parts drastically reduces the weight and space requirement of our automatic washing machine compared the weight and space requirement of prior art automatic washing machines. 
     A feature of our automatic washing machine is a collapsible container or vessel at least partially constructed in the form of a flexible bag, to contain a laundry solution such as water, and items of laundry to be washed. 
     A feature of our automatic washing machine is a flexible bag which is made of material of recent technology so as to be strong, collapsible and durable. An example of such a material is polyurethane coated fabric woven from aramid fiber. 
     A feature of our automatic washing machine is a scrubbing action for scrubbing items of laundry inside a flexible bag. 
     A feature of our automatic washing machine is vacuum wringing, which is the application of atmospheric pressure to wring the water from the laundry inside a collapsed flexible container. This vacuum wringing eliminates the vibration of the spin cycle which has been vital to prior art machines. 
     Scrubbing Features 
     A feature of our automatic washing machine is a choice of scrubbing actions such as agitation, vibration, rubbing, or other actions obvious to one versed in the art. Examples of such possible actions are: alternating deformation of the bag, injection and extraction of fluid into and out from the bag, motion imparted from a vibrating device inside the bag, motion imparted from a vibrating device outside the bag, circulating fluid inside the bag, circulating air bubbles within the fluid, rapid vibration of the fluid which results in cavitation, and other actions as may be obvious to one versed in the art. 
     In an embodiment, a method of agitation may be at least one or a combination of at least two scrubbing actions. 
     In an embodiment, a method of agitation is the use of multiple frequencies. A low frequency of agitation resulting in a sloshing action is augmented by a higher frequency agitating action resulting in cavitation. 
     In an embodiment, audio frequency vibration in the form of music is used alone or in combination with another frequency of agitating action. Music is from a conventional external source such as a home or portable stereo, fed to our automatic washing machine through an audio cable. 
     In an embodiment, motion of the laundry items being washed is accomplished by urging a circulating flow of water in the bag, and agitation is accomplished by reversing the flow of water in the bag. 
     In an embodiment, a manifold with water jets in at least two directions is used for reversing the flow of water. Each of the directions is used independently. 
     In an embodiment, a conventional reversible pump is used for reversing the flow of water. 
     In an embodiment, reversing the flow of water is accomplished by conventional automatically operated valves. 
     In an embodiment, any other washing or cleaning fluid obvious to one versed in the art may be substituted for water. 
     Space Saving Features 
     Our automatic washing machine occupies space normally dedicated to living only when in use. When use is finished living space again returns to be used for other activities of living. 
     Our automatic washing machine easily and conveniently collapses when not in use. With no requirement for a bulky agitator in our automatic washing machine the space occupied by the bag equivalent of a tub is reduced to negligible size for storage. 
     Our automatic washing machine is energy and space efficient. With no requirement for a steel enclosure, nor a steel water containing tub, nor a steel spinning tub, nor a bulky agitator, the mechanical apparatus of our automatic washing machine is much smaller and lighter. Being much smaller and lighter reduces the power required. With less power required to operate, a smaller motor and auxiliary apparatus are permitted. This further reduces the weight and results in the option to use lighter plastic instead of metal for the supporting structure Less weight and smaller motor result in increased energy efficiency. 
     Our automatic washing machine is able to be carried by one hand similar to a suitcase. When collapsed the present invention is carried out of the way when not in use. Light as a vacuum cleaner, the present invention is transportable. It can be easily carried as a piece of luggage while traveling. 
     The present invention stores easily in small space in a closet or on a shelf. 
     In an embodiment, the washing machine of this invention is produced in a form that can be mounted inside a wall of a house. 
     Our automatic washing machine enables those living in a house, apartment, or mobile home which is constructed without an area dedicated for the laundry, to enjoy the convenience of having a laundry facility in the home. 
     Control Features 
     Still another feature of our automatic washing machine is a controller which controls the various operations of the machine such that the washing proceeds automatically once the machine is loaded and turned on. 
     In an embodiment, as in prior art machines, a micro processor is used for control and logic means. 
     In an embodiment, as in prior art machines, a selector is provided for selection among multiple choices of the various phases and timing of the cleaning cycle depending upon the severity of the cleaning desired. 
     In an embodiment, as in prior art machines, a display is provided to keep the operator informed as to the progress of the cycle, and to alert the operator of any irregularities. 
     Filling Features 
     In an embodiment, as in prior art machines, an inlet and an outlet are provided to fill the machine with water and to empty it respectively. 
     In an embodiment, as in prior art machines, a water level sensing device is provided. 
     In an embodiment, as in prior art machines, a water pressure sensing device is provided to sense the level of water. 
     In an embodiment, a sensing device is provided detecting any leakage of the flexible bag before filling it with water. Such a sensing device may utilize air pressure inside the bag. 
     In an embodiment, a tilt sensor is used to prevent spilling water. 
     In an embodiment, the bag may be tapered so as to become narrower toward the top than at the bottom to overcome the tendency for the water filled bag to bulge or lean to one side and become unstable. 
     In an embodiment, as in prior art machines, a means is provided internal to the washing machine for mixing hot and cold water to achieve the desired water temperature. 
     In another embodiment, as in prior art machines, a means for controlling the water temperature is external in the form of a mixing faucet which supplies the water pre-mixed to the desired temperature. 
     Environmental Features 
     A feature of our automatic washing machine is increased efficiency gained by the use of a built in water treating device. Such devices include those utilizing various magnetic, ionic, electrolytic, electronic, cavitation, and radiation physical phenomena and as such are described in the literature and familiar to one versed in the art 
     In an embodiment, a water treating process is the generating of hydroxyl ions in wash and rinse water by the electrolytic action of water contact with an electrically polarized material of which the washing bag is made, or which is make into the bag. An example of such a material is tourmaline. 
     In our automatic washing machine a flexible bag muffles the sound of washing and is quieter than the prior art while in operation. 
     In an embodiment, our automatic washing action generates a pleasant sound of music when operating. 
     Our automatic washing machine results in less injury to garments by elimination of the requirement for a mechanical agitator. 
     The present invention results in increased cleaning efficiency due to combined action of low frequency and high frequency agitation. 
     The aforementioned examples of features of the invention, will, in part, become obvious from the following more detailed description of the invention, taken in conjunction with the accompanying drawings, which form an integral part thereof. Although the list above contains many features, these should not be construed as limiting the scope of the invention but merely as providing illustrations of some of the presently preferred embodiments of the invention. This list is not to be taken as a complete list of the features obvious to one versed in the art, but as examples of many other features of prior art washing machines which are obviously adaptable to our machine. 
     Theoretical Basis 
     It may be helpful to understand the theory behind some features of this invention. While we believe this theory to be valid, we do not wish to be limited thereto as other considerations may be pertinent. The validity of the invention has been empirically established. 
     Overcoming Design Tradeoff Paradox 
     Conventional automatic washing machines must be big for the following reasons: 1) Automatic washing machines of the prior art use a washing method that requires an agitator to drag the clothes back and forth in the water. This agitator is large and bulky. 2) Automatic washing machines of the prior art use centrifugal force to extract the water between and after the dousing cycles of washing and rinsing. In practical use the load is not balanced and the machine must be heavy to keep the machine in place during the spinning cycle. This spinning cycle and the agitation method result in the requirement for several items which make the machine heavy, large, and non movable. These items include, 
     (a) a heavy rigid metal enclosure, 
     (b) a heavy metal tub for containing water, 
     (c) a heavy metal perforated tub for washing and spinning, 
     (d) an agitator to drag the clothes back and forth in the water. 
     (e) a heavy metal transmission, 
     (f) a heavy large motor with sufficient power to move the heavy moving parts, 
     Therefore, with the above design requirements, any attempt to make a machine of reduced size or weight is met with the required tradeoff of reduced capacity. 
     To eliminate this required tradeoff of reduced capacity is the challenge. To design an automatic washing machine with equal or increased capacity and efficiency while having less weight and size requires overcoming this seeming paradox. The revolutionary solution which eliminates the requirements for the tradeoff has several parts and was unobvious.

     It has been found that if a plastic grocery bag is tied shut with fruit and water inside, nearly devoid of but including some air, and alternately squeeze it first on one side with one hand and then on the other side with the other hand, causing the water to rush by the fruit, being held in close proximity to the fruit by the plastic bag, the fruit is quickly washed with little abrasion damage to the fruit. Much riper fruit can be washed without damage by this method than by the spraying water method. 
     This method of washing is adapted to laundering clothes in this invention with the result of superior cleaning and less damage to the clothes being laundered. By experimentation, it been found that if a plastic grocery bag is tied shut with articles of laundry and water inside, nearly devoid of but including some air, and alternately squeezed first on one side with one hand and then on the other side with the other hand, a violent washing action is set up with little energy required. Such washing action is much less damaging to the laundry items. Yet, the laundry items are cleaned as effectively as though they were cleaned by the more destructive method of rubbing. 
     Of course, eventually the plastic grocery bag breaks and the water spills out. The grocery bag is not practical for that reason. However, with the recent advances in technology, there are much stronger materials available. An example of such a material is polyurethane coated fabric woven from aramid fiber. 
     A sheath of polyurethane coated fabric woven from aramid fiber may be used for making the flexible bag. However, other types of less expensive materials can obviously be substituted. A list of examples of obvious desirable properties of the material to use for construction of the flexible bag includes but is not limited to: 
     (a) flexible, such that it will collapse, but not stretch out of shape, 
     (b) strong, such that it is puncture and stretch resistant, 
     (c) durable, such that it will last for a thousand washes minimum, 
     (d) abrasion resistant, 
     (e) detergent resistant, 
     (f) bleach resistant, 
     (g) cleaning fluid resistant, 
     (h) corrosion resistant, 
     (i) hot water resistant, such that it will be able to stand up when filled with several gallons of hot water, 
     (j) mildew resistant, 
     (k) dimensionally stable, such that it will not stretch with age, such that it will be able to contain air pressure, 
     (l) non-toxic, 
     (m) able to withstand ultra sonic energy, 
     (n) unaffected by dye, 
     (o) electrically conductive or non conductive as is required by the particular embodiment, 
     (p) electrically polarized as is required by the particular embodiment, 
     and other desirable properties as is necessary for the functioning as described herein. 
     2. Water Extraction Method Breakthrough 
     It been found that if a plastic grocery bag is tied shut with articles of laundry and water inside, and a vacuum applied inside the bag, the grocery bag collapses due to atmospheric pressure. This collapse presses the water out of the articles of laundry inside the bag. Even more water is extracted by both mechanical and evaporative removal, when air is repeatedly allowed to re-enter the evacuated bag and the bag again evacuated. This method of water extraction is ideal for an automatic washing machine using a flexible bag for the washing container. The reduced atmospheric pressure at higher elevations may require artificial assistance. This reduced atmospheric pressure can be assisted easily by doubling the bag such that one bag is inside the other. Supplemental air pressure could be applied between the two bags to assist the atmospheric pressure in collapsing the inner bag, thus effectively wringing the water from the laundry. This method of supplemental air pressure may be used even at sea level if dryer laundry is desired. Thus, the spin cycle of prior art washing machines is eliminated. 
     With the spin cycle gone, the heavy parts requirement is gone. It may seem paradoxical that replacing big parts with small parts, metal with plastic and rigid with flexible, will improve the capacity and the cleaning properties of a washing machine. However, the result has been empirically verified. With this invention, less works better. 
     Water Treatment Theory 
     There are various water treatment methods in the prior art that empirically have been shown to improve the cleaning effectiveness of water. Water softening methods result in less soap or detergent being required. Magnetic water treatment prevents and removes lime scale. Electrolytic or ionic treatment improves the cleaning properties of water. Hypothetically this improvement is attributed to the reduction of the surface tension due to ion release. Other methods of ion release are found in the prior art, and obviously are adaptable to the present invention. 
     One method of ion release in the prior art that is easily adapted to the present invention is described in U.S. Pat. No. 5,309,739 to Lee (1994). In his patent, Lee uses tourmaline, an electrically polarized material which has been demonstrated to produce an increase in the effectiveness of the cleaning ability of water when the water is agitated in the immediate vicinity of the electrically polarized material. In our automatic washing machine tourmaline may be used, or alternatively, the bag may be made of a manufactured electrically polarized material. Additionally, the washing action can result in agitation of the water in the immediately vicinity of the surface of the bag which is electrically polarized, resulting in that same increase in washing effectiveness. 
     The increased cleaning effectiveness described in U.S. Pat. No. 5,309,739 to Lee (1994) is attributed by Lee to ion generation. Other methods of ion generation are described in other patents as mentioned in the prior arts section above. Obviously, any of these methods are adaptable to our inventive automatic washing machine. 
     U.S. Pat. No. 5,599,455 to Hukai (1997) presents a theoretical basis for the improved cleaning effectiveness of tourmaline treated water which attributes the effect to the generation of hydroxyl ions (H 3 O 2   − ) and hydronium ions (H 3 O + ) both having detergency. Other hypothetical explanations are abundant in the literature. One hypothesis is that the ions improve the washing effectiveness of the clothes washing machine by lowering the surface tension of the wash water due to the ionic surface active effect. It is natural that when the surface tension of the wash water is reduced, the amount of detergent necessary to clean the laundry is also reduced. 
     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 
     As will become obvious, there are multiple preferred embodiments of the present invention. One is a stand alone unit, fully collapsible into a suitcase, another is a unit designed to be built into a wall of a house, others will be obvious adaptations to the environment where the invention will be used or stored. The same part numbers are used for the same functional part in all of the figs even though the shape may be different in different embodiments. 
     FIG. 1 illustrates an example of an automatic washing machine illustrating the major components necessary in an automatic washing machine design according to the prior art. The machine of the prior art comprises a rigid metal enclosure  20 , a water containing tub  22 , a perforated washing and spinning tub  24 , a heavy transmission  26 , a heavy motor  28 , a bulky agitator  30 , and many other smaller conventional parts such as a control panel (not shown) well known to anyone versed in the art. Motor  28  drives transmission  26  which in turn drives agitator  30 , causing agitator  30  to reciprocate, or drives spinning tub  24  causing it to spin, depending on which cycle is currently in progress. In prior art automatic washing machines these illustrated parts are a necessary part of the design to make the machine automatic. 
     The prior art design for a washing machine requires agitator  30  for scrubbing the clothes. Motor  28 , and transmission  26  are necessary to drive agitator  30 . 
     The prior art design for a washing machine to be automatic requires a method of removing the water from the clothes without lifting the clothes from the water. To accomplish this spinning tub  24  is required. Motor  28 , and transmission  26  are necessary to drive spinning tub  24  This design requires the machine to be much heavier than the load of clothes being spun because the load in practical use is never completely balanced. This imbalance causes the machine to move around during the spin cycle unless the machine is heavy enough to stay in place. 
     In using the prior art machine of FIG. 1, the top is opened, dirty clothes and a little detergent are put inside, the top is closed, the desired cycle is selected, and the power is turned on. The machine automatically begins to fill with water. Later, the operator returns, opens the top, and removes the clean clothes. 
     FIG. 2 illustrates a first embodiment of the automatic washing machine of the present invention. This automatic washing machine has a rigid housing, or base  32  of which the top portion is the lower portion of a water container  34 . The top portion of container  34  is a flexible bag  36 . Inside the lower portion of housing  32  are a water pump  38 , an air pump  40 , a controlling device  42 , a flow diverter  44 , and a water distribution manifold  46 . Inside container  34  is a screen  52 , and a pair of water jets  54   a  and  54   b.  A conventional filling hoses  78 , conventional check valve (not shown), conventional fill valves (not shown), a drain hose  80 , and conventional power cord (not shown) complete the apparatus of the automatic washing machine. Flexible bag  36  is collapsible so as to fold down into the top portion of housing  32  for storage. Flexible bag  36  is made of material of recent technology so as to be strong, collapsible and durable. An example of such a material is polyurethane coated fabric woven from aramid fiber. An opening  58  at the top of flexible bag  36  is opened and closed by means of a drawstring tie  60 . Housing  32  and screen  52  are made of conventional plastic having a heat resistance up to over 200 degrees Fahrenheit. Water pump  38  is a conventional water pump of similar size and capacity that would be used on a conventional automatic electric dishwasher. Water pump  38  is connected to pump water from the water container  34  portion of housing  32  to flow diverter  44 , Flow diverter  44  is a series of conventional valves (not shown) controlled by controlling devise  42 . Flow diverter  44  is connected to supply water from water pump  38  through water distribution manifold  46  to waterjets  54   a  and  54   b  alternately for agitating, or to drain hose  80  for emptying. Air pump  40  is a conventional vacuum cleaner type air pump and is connected to force air from the atmosphere into container  34  or out of container  34  into the drain hose, as controlled by controlling device  42 . A conventional check valve (not shown) is part of air pump  40  to prevent water from flowing out an atmospheric air intake vent (not shown). Controlling device  42  is a standard timing and control device. The wiring and constructional details of timers for operating a machine cycle are so well known to those skilled in the art, that no description of them is contained herein. 
     The washing and rinsing action, and the water extraction method of the inventive machine are of unique design and are described in detail in FIGS. 6 a  to  7   g.    
     In use, the inventive automatic washing machine of FIG. 2 is quite similar to the use of the automatic washing machine of FIG. 1 of the prior art. In using the prior art machine of FIG. 1, the top is opened, dirty clothes and a little detergent are put inside, the top is closed, the desired cycle is selected, and the power is turned on. The machine automatically begins to fill with water. Later, the operator returns, opens the top, and removes the clean clothes. Likewise, in using the inventive machine of FIG. 2, the top is opened, dirty clothes and a little detergent are put inside, the top is closed, the desired cycle is selected, and the power is turned on. The machine automatically begins to fill with water. Later, the operator returns, opens the top, and removes the clean clothes. Thus from the operators perspective, the operation of the inventive machine of FIG. 2 is identical to the familiar operation of the prior art machine of FIG.  1 . 
     The inventive automatic washing machine of FIG. 2, however, is much smaller and lighter while still having essentially the same load capacity as the prior art machine of FIG.  1 : 
     Where the prior art machine of FIG. 1 has a heavy, rigid metal enclosure  20  and a heavy rigid water containing tub  22 , the inventive machine of FIG. 2 has combined the two into a rigid housing, or base  32  of much lower profile and made of a lighter material. An example of the lighter material is plastic. The lower portion of tub  22  in FIG. 1 has been built into the upper portion of housing  32  of FIG.  2 . The upper portion of tub  22  in FIG. 1 has been replaced in FIG. 2 with a flexible bag  36  having opening  58  at the top which is secured by a drawstring tie  60 . In FIG. 2 upper portion of housing  32  and flexible bag  36  together make a container  34  for holding a dousing water  74  for washing or rinsing. 
     Where the prior art machine of FIG. 1 has a heavy metal perforated washing and spinning tub  24 , the inventive machine of FIG. 2 has none. The water extraction method of the inventive machine of FIG. 2 has eliminated the need for spinning tub  24  of the prior art machine of FIG.  1 . 
     Where the prior art machine of FIG. 1 has a bulky agitator  30  taking space in tub  22 , the inventive machine of FIG. 2 has a pair of waterjets  54   a  and  54   b.  In the inventive machine of FIG. 2 no space is taken up inside container  34  with bulky parts. 
     Elimination of spinning tub  24  and agitator  30  also eliminates the need for transmission  26  and heavy motor  28  of FIG.  1 . The inventive machine of FIG. 2 replaces those heavy parts with a water pump  38  and air pump  40  which are smaller and lighter and fit easily inside housing  32 . 
     The remaining parts necessary to complete an automatic washing machine are familiar conventional parts which are obvious to one versed in the art, such as mixing and filling valves (not shown), filling hose  78  and drain  80 , a power cord (not shown), a conventional controller (not shown) and other items irrelevant to the invention. 
     Thus, with the elimination of the need for the six most heavy and bulky parts of the prior art, the inventive machine of FIG. 2 is but a fraction of the size and weight, while still having the same capacity and functionality as the prior art machine. 
     FIG. 3 a  and FIG. 3 b  illustrate a preferred embodiment of the automatic washing machine of the present invention. This preferred embodiment is very similar to the embodiment illustrated in FIG. 2, but has no opening in the top of bag  36 . Instead, in this preferred embodiment, container  34  is opened by separating bag  36  portion of container  34  from housing  32  portion of container  34 . There is a bag holder  68  around the bottom opening of bag  36  which holds bag  36  securely against a seal  66  when bag  36  and holder  68  are closed down onto housing  32 . A hinge  62  and a clasp  64  secures holder  68  to seal  66 . A clothes retaining rack  70  is also attached to hinge  62  and snaps into bag holder  68 . 
     The washing and rinsing action, and the water extraction method of the inventive machine are of unique design and are described in detail in FIGS. 6 a  to  7   g.    
     The use of this embodiment of the automatic washing machine is very similar to the use of the machine illustrated in FIG.  2 . The difference in use is in the opening of bag  36  to insert and remove the articles of laundry. Instead of opening drawstring  60 , to open bag  36 , in the embodiment of FIG. 3 a  and FIG. 3 b,  the operator opens clasp  64  and raises bag holder  68  including bag  36  in a similar manner as opening the lid on a conventional prior art top loading washing machine. Once bag holder  68  is raised, rack  70  is snapped out of bag holder  68  and the dirty clothes are put into bag  36 . After bag  36  is filled, rack  70  is snapped back into bag holder  68  and bag holder  68  is lowered and attached with clasp  64 , thus insuring a water tight closure against seal  66  on housing  32 . 
     FIG. 3 b  also illustrates the conventional water, drain, and power hookups used in this embodiment. A fill hose  78  with a quick release hose connectors  84  and  84 ′ on either end, and a drain hose  80  with a quick release hose connector  84  on the end connected to housing  32  provide a temporary connection to a water tap  86  and a sink with drain  88 . A power cord  82  with conventional plug connectors on both ends provides a temporary connection to electric power while in use. 
     The use of the conventional water, drain, and power hookups used in this embodiment is simplified by quick release hose connectors  84 . Water hose  78 , drain hose  80  and power cord  82  are removed from their place of storage. Water hose  78  and drain hose  80  are connected to their respective mating quick release hose connector  84  on housing  32 . The other end of water hose  78  is connected to mating quick release connector  84 ′ previously installed on a convenient water tap. The other end of drain hose  80  is hooked over the edge of a sink with drain such that water from drain hose  80  goes down the drain. Connecting power cord  82  to an appropriate connector  90  on housing  32  and to a conventional electric outlet (not shown) complete the hook-up. 
     FIGS. 4 a  to  4   d  illustrate an alternate preferred embodiment of the automatic washing machine of the present invention. FIG. 4 a  is a plan view with a suitcase type lid  96  swung open. FIG. 4 b  is a side view with lid  96  removed. FIG. 4 c  is an end view showing bag  36  and housing  32  to be less tall than wide. FIG. 4 d  is a perspective view prepared for storage. This alternate preferred embodiment is very similar to the embodiment illustrated in FIG. 3 a  and FIG. 3 b,  which has a vertically oriented bag  36 , except the orientation of bag  36  of the embodiment shown in FIGS. 4 a  to  4   d  is horizontal and bag  36  separates from housing  32  opening to the side (not shown), in the same direction as lid  96  is shown open. Instead of bag  36  setting on housing  32 , this embodiment has bag  36  laying on a horizontal surface (not shown) and housing  32  standing at one end of bag  36 . The arrangement of hinge  62  and clasp  64  are the same. There is no need for rack  70  of FIG. 3, because articles  76  are inserted deeper into bag  36  of this embodiment as the bag of this embodiment is longer. To open this machine housing  32  is swung away from bag  36 . A control panel  92  is conveniently located on the top side of housing  32 . When closed and operating, water  75  inside bag  36  is supported by any horizontal surface such as a floor (not shown) on which bag  36  is laying. Air  72  in bag  36  is in contact with housing  32  making the sensing of the level of water simpler. In this embodiment, the vertical dimension of housing  32  need only be a little greater than the depth of water  74 . This results in housing  32  being smaller and more compact for storage. When in use, bag  36  hangs out the side of housing  32 , which appears like a suitcase with a bag hanging out of it. When not in use, bag  36  collapses conveniently into housing  32  and housing  32  is converted into a suitcase  94 . Suitcase lid  96  swings closed over the bag (and other attachments). A carrying handle  98  on top of housing  32  provides a convenient way to carry the machine into storage. 
     FIGS. 5 a , to  5   c  illustrate a wall mounted embodiment of the automatic washing machine of the present invention. Housing  32  is the door of a front loading automatic washing machine of this invention when the machine is mounted inside a wall. From the front the wall mounting model looks similar to the separate freezing compartment door of a top freezer refrigerator. This is illustrated in FIG. 5 a.  This embodiment of the automatic washing machine is very similar to the embodiment illustrated in FIGS. 4 a  to  4   d.  The machine of FIGS. 4 a  to  4   d,  as shown in FIG. 5 b,  has been modified and fitted with a wall mount bracket  102  and a backboard  104 , that folds down to become the surface on which bag  36  rests. Backboard  104  is connected to wall mount bracket  102  by a backboard hinge  106 . Backboard  104  is normally folded up against the wall on the back side of the wall so as to not use any space out of the room on the back side of the wall. This folded configuration is illustrated in FIG. 5 c.  The configuration of hinge  62  is of somewhat different design to accommodate the wall bracket, but serves the same purpose as in the other embodiments. Housing  32  is constructed in the shape of a deep door which nearly fills the depth of the wall. Seal  66  is at the back edge of housing  32  so as to mate with bag holder  68 . Bag holder  68  is permanently affixed to wall bracket  102  near the back side of the wall. Water hose  78 , drain hose  80 , and power cord  82  are permanently affixed to housing  32  with conventional strain relief (not shown), and are permanently affixed to plumbing and power inside the wall as in a conventional washing machine installation (not shown). In this embodiment seal  66  and bag holder  68  are oval or rectangular in shape, as in FIGS. 4 a  to  4   d,  rather than round as in some other embodiments, otherwise they function the same. When put away, bag  36  is collapsed into housing  32  and covered by backboard  104 . When in use, backboard  104  is lowered down to a nearly horizontal position and bag  36  expands rearward and rests on backboard  104 . A sideboard  110  on each side of backboard  104  and attached to backboard  104  keeps bag  36  from hanging over the side of backboard  104 . Handle  100  serves to open the door which is housing  32 . The door is equipped with a conventional interlock (not shown) to prevent opening the door at the wrong time and spilling water. Such a conventional interlock is common on prior art front loading automatic washing machines. 
     FIGS. 6 a  to  6   d  are included to illustrate the water extraction cycle of an automatic washing machine according to the present invention. This water extraction cycle is quite different than the water extraction cycle of the conventional washing machine of the prior art. This water extraction cycle can be visualized as having two phases. 
     In the first phase, water and air are pumped out. In the second phase, air is pumped in. The two phases are repeated a reasonable number of times to extract as much water as is practical without damage to the clothes. 
     FIG. 6 a  illustrates phase  1 . In Phase  1  air and water is pumped out of container  34 . After water pump  38  (not shown) pumps out all the readily available water, vacuum  114  is applied from air pump  40  (not shown) to evacuate container  34 , causing available atmospheric pressure  116  to collapse bag  36 , pressing articles  76  to screen  52 , thereby wringing water from articles  76 . After a short time of the wringing of phase  1 , phase  2  is started. 
     FIG. 6 b  illustrates phase  2 . In Phase  2  air pressure from air pump  40  is forced into container  34  causing articles  76  to relax and bag  36  to inflate. 
     Again, after a predetermined short time, phase  1  and phase  2  are repeated a predetermined number of times. This repeated inflating and deflating of bag  36  moves air through articles  76  and results in both mechanical and evaporative removal of water. The final water extraction cycle contains a predetermined greater number of repeats than an extraction cycle that occurs before a rinse cycle. It is not as necessary to get articles  76  as dry when the next step, see FIG. 11, is entering a rinse cycle where they again get wet. 
     FIG. 6 c  illustrates a means for wringing increased amounts of water from articles  76  when drier articles  76  are desired. Atmospheric pressure  116  of phase  1  is assisted by air pressure from a pump assembly  122 , shown in FIG. 6 d.  An outer bag  120  in addition to bag  36  is supplied to contain the assisting air pressure. An air pressure channel  118  conducts the additional air pressure from pump assembly  122  into air containing bag  120 . Simultaneously vacuum is applied from pump assembly  122 . This additional air pressure assists the natural atmospheric pressure collapse bag  36  and wrings additional water from the clothes. 
     FIG. 6 d  illustrates air and water pump assembly  122  which is somewhat non-standard and would be suited for this application. Pump assembly  122  replaces three separate pumps with their own electric motors. An electric motor  124 , water pump  38 , air pumps  40   a  and  40   b,  a check valve a  126 , and a check valve b  128 , are parts of pump assembly  122 . Electric motor  124  is a multi speed motor which speeds up when the load of water pump  38  is gone due to all the water being pumped out. When motor  124  is running at high speed, vacuum is available from air pump  40   a  and air pressure is available from air pump  40   b.  Check valves  126  and  128  prevent back flow. 
     FIGS. 7 a  to  7   g  show various views illustrating the detail of the agitation and scrubbing action of the washing and/or rinsing cycle of an automatic washing machine according to the present invention. The scrubbing action occurs as a result of mechanical agitation. As a result of this scrubbing action, the clothes wash against each other, against the sides of the washing machine, against air bubbles in the water, and against the water itself. This scrubbing accomplishes several things including the loosening of solid material on the surface of and imbedded in the fabric of the clothing, the dissolving of solids, the generation of ions, the emulsification of oil, and the rinsing away of foreign material, be it solid, emulsified, or dissolved. Various embodiments have different methods of inducing agitation. 
     FIG. 7 a  illustrates the water jet method of inducing action. Action is induced in water  74  inside bag  36  by means of water jets  54   a  and  54   b  through which water is forced by water pump  38 . Flow of water  74  inside bag  36  follows a flow pattern  130   a  or a flow pattern  130   b,  depending on the predetermined direction and predetermined angle jet  54   a  and jet  54   b  are mounted, and on which of these jets are currently in use. Flow diverter  44  is connected after water pump  38  and before jets  54   a  and  54   b.  Flow diverter  40 , under the control of controlling device  42  (not shown), causes flow to be diverted to one or the other, or to both simultaneously. Jets  54   a  and  54   b  are independently active causing the pattern of flow to be at one time in one direction and at another time in another direction, thus disrupting flow pattern  130   a  or  130   b  and causing agitation. Different predetermined mounting positions and predetermined numbers of jets  54  are used in different embodiments to achieve the same results as is obvious to one versed in the art. 
     FIG. 7 b  illustrates the water jet plus air bubbles method of inducing action. Action is induced in water  74  inside bag  36  by means of water jets  54   a  and  54   b  through which water and air are forced by water pump  38  and air pump  40 . This is achieved by locating air pump  40  such that air is introduced in the flow of water between water pump  38  and flow diverter  44 . Excess air rises to the top of the wash water and is allowed to escape via an air vent or duct  132  which recycles the air to air pump  40 . Air bubbles in the water increases the action over water alone. While washing without sudsing detergent or soap, air bubbles would give the pleasing appearance of suds to homemakers who judge cleaning power by the amount of suds. When using sudsing detergent, a control cycle would be selected that did not use the air feature. The vertical embodiment is illustrated in FIG. 7 b.  However, implementation in the horizontal, or front loader, embodiment (implementation not shown) would result in a simpler arrangement of duct  132 . 
     FIG. 7 c  illustrates the low frequency vibrating disk method of inducing action. Action is induced in water  74  inside bag  36  by means of a low frequency vibrating disk  134  causing a conventional resonance phenomena (not shown). Disk  134  is driven into vertical vibration by the drive force of a vibrating drive unit  136 . An alternate location for disk  134  is above screen  52  (alternate location not shown). 
     FIG. 7 d  illustrates the reversible rotating disk method of inducing action. Action is induced in water  74  inside bag  36  (shown in FIG. 7 c ) by means of a reversible rotating disk  138  causing a conventional resonance phenomena (not shown) similar to low frequency vibrating disk  134  shown in FIG. 7 c.  Disk  138  in FIG. 7 d  is rotationally driven by the drive force of a reversible rotating drive unit  140 . Rotating disk  138  differs from vibrating disk  136  in that rotating disk  138  has a predetermined tilt  142  to one side such that when rotating, it moves water up and down on opposite sides of disk  138 . The rotation of disk  138  also sets up a swirling action in the water. The rotation direction of disk  138  reverses every predetermined number of seconds to prevent setting up a violent swirling action in the water. This reversal pattern produces agitation instead of swirling. 
     FIG. 7 e  illustrates the sloshing sideboards or baseboard method of inducing action. Action is induced in water  74  inside bag  36  by means of a portion or portions of sloshing sideboards or baseboard resulting in squeezing, shaking, jiggling, or bumping. This action causes a sloshing movement of the contents of bag  36 . A flexibly movable portion  144  of housing  32  is jostled by the force of an actuator  146  through an actuator arm  148 . Portion  144  is flexibly movable by virtue of a flex joint  150  and a pivot or hinge  151 . In FIG. 7 e  one side is shown, however, multiple sides are so equipped resulting in opposing motion. 
     FIG. 7 f  illustrates the ultra sonic vibration method of inducing action. Action is induced in water  74  inside bag  36  by means of inducing ultra sonic vibrations resulting in cavitation, a very effective means of cleaning. An ultrasonic generator  152  is electrically connected to an ultrasonic vibrator  154 . Ultrasonic vibrator  154  and an ultrasonic vibration plate  156  are mounted on housing  32  such that ultrasonic vibrations are induced in water  74 . 
     FIG. 7 g  illustrates the sonic vibration method of inducing action. Action is induced in water  74  inside bag  36  by means of inducing sonic vibrations resulting in cavitation, a very effective means of cleaning. An underwater speaker  160  is mounted inside water container  34  portion of housing  32 . Speaker  160  is electrically driven by a sound generator/power amplifier  158 . Optionally, music or other sound from a conventional external source such as a portable or home stereo (not shown) may be plugged into an input jack  162  on control panel connected to amplifier  158 . When the external source produces music, then music is the waveform of the sonic vibration which produces the cleaning action, and the pleasant sound of music will emanate from the washing machine. 
     FIG. 8 illustrates a combination of multiple methods of inducing agitation combined in a single embodiment. The water jet method action is induced in water  74  inside bag  36  by means of water jets  54   a  and  54   b  through which water is forced by water pump  38  as is shown in FIG. 7 a.  Or, optionally, by operator selection on control panel  92 , the water jet plus air bubbles action is induced in water  74  inside bag  36  by means of water jets  54   a  and  54   b  through which water and air are forced by water pump  38  and air pump  40  as shown in FIG. 7 b.  Additionally, in the same embodiment, as shown in FIG. 7 g,  sonic or ultrasonic vibration action is induced in water  74  inside bag  36  by use of an underwater transducer  164  mounted inside water container  34  portion of housing  32 . Transducer  164  is electrically driven by a waveform generator/power amplifier  166 . Optionally, music or other sound from a conventional external source such as a portable or home stereo (not shown) may be plugged into an input jack  162  connected to amplifier  166 . This combination results in increased cleaning efficiency due to combined action of low frequency sloshing and high frequency vibration agitation. 
     FIGS. 9 a  to  9   e  show various views illustrating the detail of several implementations of conventional water treating devices, the inclusion of which is an object of an automatic washing machine according to the present invention. 
     FIG. 9 a  shows a built in water treatment device wherein water  74  interacts with an electrically polarized material  170  to cause electrolysis of water  74 . It has been empirically verified that electrolysis of water  74  has an effect on water  74  which is apparent softening without removing any of the dissolved solids. It has been hypothesized by those versed in the art, that electrolysis generates hydroxyl ions causing a surface active effect, thereby lowering the surface tension of water  74 . This interaction is enhanced by agitation of water  74  in the vicinity of polarized material  170  by ultrasonic vibration plate  156 . An example of electrically polarized material  170  is tourmaline in the form of a tourmaline ceramic coating. Some artificial materials such as some plastics also exhibit this electrically polarized property. In this embodiment, material  170  is a tourmaline ceramic coating on the bottom side of screen  52 . 
     Water treatment by interaction with an electrically polarized material such as tourmaline is well known by those versed in the art and is adequately described in U.S. Pat. No. 5,309,739 to Lee (1994). Lee describes a device which utilizes the generation of surface-tension-reducing hydroxyl ions for the purpose of reducing the amount of detergent required, and explains the hypothesis behind the effect. That explanation is included herein by reference. 
     FIG. 9 b  shows a built in water treatment device wherein water  74  interacts with an electrically polarized material  170 ′ to cause electrolysis of water  74 . It has been empirically verified that electrolysis of water  74  has an effect on water  74  which is apparent softening without removing any of the dissolved solids. It has been hypothesized by those versed in the art, that electrolysis generates hydroxyl ions causing a surface active effect, thereby lowering the surface tension of water  74 . This interaction is enhanced by agitation of water  74  in the vicinity of polarized material  170 ′, by water jet  54   a  and  54   b  causing a water flow  172  directed against material  170 ′. In this embodiment, material  170 ′ is an electrically polarized plastic coating on the inside of bag  36 , which becomes more electrically polarized due to the friction of water flow  172  against polarized material  170 ′. 
     FIG. 9 c  shows a built in water treatment device wherein water  74  interacts with an electrode  174  and an electrode  176  which are electrically isolated electrodes of different electrochemical potential resulting in electrolysis of water  74 . It has been empirically verified that electrolysis of water  74  has an effect on water  74  which is apparent softening without removing any of the dissolved solids. It has been hypothesized by those versed in the art, that electrolysis generates hydroxyl ions causing a surface active effect, thereby lowering the surface tension of water  74 . This interaction is enhanced by flow of water  74  in the vicinity of electrodes  174  and  176 . By locating electrodes  174  and  176  inside a section of pipe  178  containing water  74  as water  74  is circulated during agitation. In this embodiment, electrode  174  is made of a material containing aluminum and electrode is  176  is made of a material containing carbon. Other electrically conductive materials having different electrochemical potentials may be used. 
     Water treatment by interaction with electrically isolated electrodes of different electrochemical potential is well known by those versed in the art and is adequately described in U.S. Pat. No. 5,358,617 to Ibbott (1994). Ibbott describes a device which utilizes electrically isolated electrodes of different electrochemical potential to ionize the wash water inside a prior art washing machine for the purpose of reducing the amount of detergent required. That explanation is included herein by reference. 
     FIG. 9 d  shows a built in water treatment device wherein water  74  interacts with a magnetic field. It has been empirically verified that passing water  74  through a magnetic field  180  causes the deposition of lime scale to cease, and accumulated lime scale to decrease. This is an effect akin to softening of water without physically removing the dissolved metal ions from water  74 . It is well known to those versed in the art that this phenomenon has an effect of reducing the amount of detergent necessary to clean clothes. In this embodiment a magnet  182  is placed on one side of a section of pipe  184  and a magnet  182 ′ is placed on the opposite side of pipe  184  causing magnetic field  180  to occur inside pipe  184 . 
     FIG. 9 e  shows a built in water treatment device wherein water  74  is exposed to ultra violet radiation. It has been empirically verified that exposing laundry water  74  to ultra violet radiation kills bacteria in water  74 . An ultra violet light  186  is installed inside base  32  such that ultra violet light passes through an ultra violet light window  188  into the lower portion of water container  34 , exposing water  74  to an ultra violet radiation  192 . An ultra violet reflector  190  is installed behind ultra violet light  186  to reflect ultra violet radiation  192  into water  74 . 
     FIGS. 10 a  to  10   d  illustrate an alternate preferred embodiment of the automatic washing machine of the present invention. FIG. 10 a  is a side section view with bag  36  expanded for operation. FIG. 10 b  is the same side section view with bag  36  collapsed during the water extraction operation. FIG. 10 c  is a rear view of screen  52  showing water jet arrangement. FIG. 10 d  is a front view. This alternate preferred embodiment is very similar to the wall mounted embodiment illustrated in FIGS. 5 a  to  5   c  with the exception that housing  32 , is in the form of a yoke, similar to a donut, around a neck  196  of container  34 , container  34  being made up of bag  36  connected to housing  32  at connecting point  194 . In this arrangement the various components in housing  32  are arranged around neck  196  of container  34 . Screen  52  is a ring around neck  196  of container  34 , curved around housing  32  in a conformable way, spaced a predetermined distance away from housing  32  to provide space for water to flow between screen  52  and housing  32 . With this arrangement, a see through door  198 , permitting a view of the inside of the machine while in operation, is fitted on the opposite side of housing  32  from bag  36 . Articles  76  enter container  34  by passing through neck  196  of container  34 . The embodiment shown here is built into a telescoping suitcase  200 . The side of the suitcase with the door is the front of the machine and appears to the operator very similar to a conventional front loading washing machine of the prior art. The back of the suitcase telescopes out to make room for bag  36  to expand while in use. In the particular embodiment shown, a left set of water jets  202 , in a manner explained for water jet  54   a  of FIG. 7 a  causes agitation in a clockwise direction. A right set of waterjets  204 , in a manner explained for to water jet  54   b  of FIG. 7 a  causes agitation in a counterclockwise direction. Water treatment features (not shown) and other means of agitation, either singly or in combination (not shown) are optional features on this embodiment as well as on the others. This embodiment also, is optionally fitted with a flange to be built into a wall similar to the embodiment in FIGS. 5 a  to  5   c.    
     FIG. 11 applies to any of the many embodiments of the inventive automatic washing machine. In FIG. 11 a functional block diagram of the inventive washing method  206  illustrates the overall concepts behind the devices and methods which make up the inventive automatic washing machine, and their usage. Diagram  206  illustrates the process flow of the inventive method of washing clothes. Diagram  206  is to aid in the following explanation of the usage of the inventive automatic washing machine. The accompanying explanation refers to parts shown in the other figures above. 
     A block labeled controller  226  represents the function of controlling device  42  in FIG.  2  and other Figs. Control of the process is automatically accomplished from a step c  212  through a step g  220 . Steps before and after are under the control of the operator. 
     A step a  208  is set up machine. Setting up the machine, is accomplished differently depending on the embodiment. Basically the machine is removed from storage, opened if necessary, and connected to water, drain, and power. 
     Some embodiments are stored in a shape resembling a suitcase. The suitcase is carried from storage, opened, and the connections made as described in the explanation for FIG.  3 . 
     On some models, the water temperature is adjusted at tap  86  of FIG.  3 . 
     With the wall mounted embodiment, the water, drain, and power is permanently connected, thus simplifying set up. On this model, the backboard  104  in FIG. 5 is simply unclasped and lowered to complete the set up. 
     A step b  210  is load and select cycle. Loading the machine and selecting the cycle is accomplished very similar to performing the same function with a conventional automatic washing machine of the prior art. The machine is opened, dirty clothes are put in along with optional laundry products such as detergent, and the machine closed. On control panel  92  (shown in FIGS.  4  and  5 ), the desired cycle pattern is selected, and the power turned on. Control is thereby transferred to controlling device  42 . 
     A step c  212  is fill with water. Filling the machine with water under the control of controlling device  42  has several unobvious features. 
     First a leak test is done. As with water beds, when they were first introduced to the consumer, they met with consumer skepticism. There was fear of water spilling all over the house. The same skepticism is anticipated with the washing bag  36 . To overcome this skepticism, the consumer can be assured that a test is performed to check for leaks before filling the machine with water. Such a test is to inflate bag  36  with air to a predetermined pressure, and wait to see if the pressure drops below a predetermined pressure, indicating a leak. If a leak is detected, operation is suspended and controller  42  notifies the operator. 
     Tip over detection is accomplished. Since most embodiments are portable, and may be tipped over, a conventional tip over detector (not shown) is checked by the controller before each filling. A tip over condition could disrupt the fill level sensor and result in excessive filling. If a tip over is detected, operation is suspended and controller  42  notifies the operator. 
     Fill to predetermined level is accomplished by using a conventional fill detector/sensor (not shown). Various type devices may be used depending on the embodiment. For the vertical embodiments a conventional water pressure sensing device may be used. In the horizontal embodiments a conventional float level detector may be used. 
     In an embodiment, as in prior art machines, a conventional device (not shown) is provided internal to the washing machine for mixing hot and cold water to achieve the desired water temperature. In another embodiment, as in prior art machines, a means for controlling the water temperature is external in the form of a mixing faucet which supplies the water pre-mixed to the desired temperature. In this case this function is performed manually in step a  208 , above. 
     A step d  214  is wash. Washing action, is initiated after filling in step c  212 . Washing action occurs in various ways in different embodiments as illustrated in FIGS. 7 a  to  7   g.  Simultaneously, any water treatment device as illustrated in FIG. 9 in the particular embodiment is activated. This is a very complex step and is described in detail in FIGS. 7 a  to  9   e.    
     A step e  216  is extract water. Water extraction, is fully illustrated and described in FIGS. 6 a  to  6   d.    
     A step f  218  is fill, rinse, extract. This step  218 , is a predetermined number of repeats of step c  212 , fill with water, step d  214 ,wash, and step e  216 , extract water. Washing action is the same in the wash and the rinse cycles with the exception that any detergent added near the beginning in step b  210 , is rinsed away in the rinse cycles. However, cleaning action continues in the rinse cycles because of the water treatment features built into the machine. The number of repeats of the filling, washing action, and water extraction processes is predetermined, depending on the particular cycle pattern selected on the control panel in step b  210 . The number of repeats of the water extraction process within each repeat of the water extraction step is predetermined, depending on the particular cycle pattern selected on the control panel in step b  210 , and whether the next step is another rinse or removal in step h  222 . 
     A step g  220  is notify operator. Notification of the operator, is accomplished in the conventional way as in the prior art. It may be by a signal sound, or light, or both. Additionally any malfunctions such as a bag leak would result in some conventional signal appearing on the control panel. 
     A step h  222  is remove clean items. Removal of clean items, is accomplished in the way familiar to operators of the prior art machines. Simply open the machine and take out the clothes. 
     A step i  224  is store machine. Putting the machine into storage, is the reverse process of step a  208 . If the embodiment is the wall mounted model, simply raise the backboard to the wall in the other room and secure the clasp. If the embodiment is one of the suitcase models, simply turn off the water and remove the quick disconnect hoses, and power cord. Coil them and place them in the lid. Close the lid. Pick up suitcase and carry it into storage. 
     In Summary 
     When it is desired to wash clothes, the machine is removed from it&#39;s storage space such as a closet or shelf, and carried to a location in proximity to an electrical outlet and a water tap which has previously been fitted with a quick disconnect water connector. The water inlet/outlet hose assembly of the machine is pulled out of it&#39;s storage location of the washing machine and connected to the water tap. The electric supply cord is connected to any electrical outlet. The machine bag is opened and the dirty clothes are put into the machine along with any desired laundry product. The machine is closed. The machine cycle selector is set to the desired automatic cycle, and turned on. The machine automatically goes through the selected cycle and turns off. The machine is opened and the clean clothes are removed. The hoses and power cord are disconnected from the supply and placed into their respective storage locations in the machine. The machine is then carried back to it&#39;s storage space out of the way. 
     When the machine is manually switched on the controlling device  42  causes various functions of filling, agitating, and extraction to occur. At the proper predetermined time the water fills the bag to a predetermined level. Once the predetermined level is reached, a means for agitation is turned on for a predetermined length of time. When the predetermined length of time is expired, the water extraction function is turned on for a predetermined time interval. This cycle is repeated a predetermined number of times and a predetermined duration of each time to wash and rinse the clothes and leave the clothes with the water extracted and ready to be dried. 
     Within each of the functions of agitation and extraction, the sub functions are controlled by the control means. 
     Conclusions, Ramifications, and Scope 
     Accordingly, the reader will see that the automatic washing machine of this invention is made possible without the two tubs, an agitator, and a metal enclosure required by the prior art. Yet, all the features of the prior art are included in the present invention. Beyond the features of the prior art, are several advantages of the present invention. Living space in the home is increased as there is no need for dedication of a room of the house for a wash machine. Homes without dedicated space can have the full capability of a laundry facility in the home. The gentle yet effective washing action saves wear and tear on clothes. The gentle yet effective water extraction method saves wear and tear on clothes. The water treatment methods employed increase the efficiency and reduce the amount of detergent necessary, and therefore reduce pollution of the environment. 
     The present invention employs a flexible bag and light plastic parts to eliminate the need for those heavy metal parts. The washing action is achieved by water movement interacting with the flexible bag and other plastic parts. The water movement is a pulsating action within the water achieved by pumping, by vibrating or by shaking in or about some part of the bag with the water transmitting the action through the clothes. This not only forces the water through the clothes, but also causes the clothes to rub against each other and the bag. Thus the dirt is loosened and rinsed away. 
     Surprisingly, the rubbing between the water and the electrically polarized dielectric surface of the plastic parts or flexible bag causes a surprising increase in the washing efficiency due to the generation of ionic action in the water. Further improvement in the cleaning properties of water is accomplished by optional magnetic treatment of the water. A vacuum apparatus is used to extract liquid and air from the bag and the bag thus collapses by atmospheric pressure squeezing the clothes forcing the water out. Repeated cycles of air vacuum out of the bag, and air pressure into the bag will extract more water and fluff the clothes to result in clothes dry enough to put in a clothes dryer or to hang on hangers for final drying. Means to fill and empty the bag with water and means to control the various cycles which are obvious to those versed in the art will complete an automatic washing machine. By virtue of a collapsible bag, and the unobvious benefits it enables, an entire, normal capacity washing machine is reduced into a volume that is suitable to be stored in an out of the way place when not in use. Elimination of the heavy metal parts of the currently popular conventional automatic washing machine of the prior art results in an automatic washing machine that is light enough to be lifted by one hand and carried into storage. 
     Unlike many other attempts to fill the need for a space saving appliance, this invention operates in the manner to which the homemaker is already accustomed, and little, if any, instruction is needed. 
     This invention will fill that long recognized and unfilled need for full sized automatic laundry capability in the home without the requirement for space normally dedicated to laundry machines. The automatic washing machine of the present invention has a capacity comparable to a standard automatic washing machine without the disadvantages associated with the space and weight requirements of a standard automatic washing machine according to the prior art. This machine has broken through two major barriers in this area, size and weight. The size of a standard washing machine is over come by the machine of this invention using smaller parts and also by being collapsible. In this invention, the weight of the standard washing machine is overcome not only by the use of lighter materials, but by an unexpected efficiency of the flexible tub washing method which results in a much more energy efficient agitating system. This energy efficiency results in supporting hardware being light enough to be easily carried manually. Using a flexible bag instead of a steel tub, the flexible bag and it&#39;s contents can be set in motion at any one area and the motion is transmitted throughout the entire bag by the inter-reaction of the water, the items being washed, and the flexible bag. This eliminates an energy wasting need for an agitator to drag the clothes back and forth. 
     This flexible bag has another unexpected advantage in that in the pumping out of the water with a vacuum pump, the bag collapses and actually wrings the water out by transmitting the outside atmospheric pressure to the clothes. The previous need for the water to be either wrung out by passing the clothes through rollers, or extracted by the centrifugal force of spinning has been eliminated. 
     The invention has uses beyond normal home laundry. Dry cleaning, car parts washing, farm produce washing, separation of clay from gold in a mining operation are but a few of the obvious uses. 
     Many obvious modifications come to mind that have not been included above. Examples of such things that anyone versed in the art would assume to be obvious are: 
     The size is not limited to that of the standard household washing machine. A much larger or smaller version is obviously within the scope of the invention. 
     Substitution of various assemblies for individual components, or the addition or deletion of check valves in place of controlled valves are but a few among many of the various options. 
     Cleaning fluid or other washing solution could be used instead of water. 
     Water treatment device may be in line, cartridge, or designed into the structure of the apparatus. Water treatment device may be built in or may be a replaceable cartridge. Water treatment device may be an option depending on water condition in users area. 
     The washing container does not have to be round. It may be oval or some other shape. It may have a rigid side and be only partially collapsible. 
     The screen does not have to be flat. It could be curved. Many parts that have been shown flat could be curved. Corners could be rounded. The base housing could be smaller than the bag. 
     The air pump and the vacuum pump may be designed into a single unit using a single motor. The motor may be multi speed, depending on the load, whether it is water or air. The pump unit may even be in combination with control valves. 
     The closure means of the top opening bag need not be a drawstring. It can be other means such as a water proof zipper, a clamp, or other conventional closing device. 
     Some embodiments could even be operated in case of a lack of power. the bag could be loaded, massaged by hand or foot, then the clothing removed and hand wrung. 
     In an alternate design for a horizontal embodiment, the suitcase lid can be the horizontal surface with the hinge on the back (bottom) and the clasp on the top near the handle. The suitcase can be opened in a standing position and the lid lay back on the floor with the bag falling into the lid. The bag and bag holder is then opened away from the housing for clothes to be inserted or removed. 
     The hoses and power cord can be stored in the lid when not in use. 
     On models that open other than at the top of the bag, an interlock could be used as in conventional front loader machines, to prevent opening at the wrong time and spilling water. 
     While plastic has been described, a more rugged embodiment could have many parts made of metal. 
     The bag may be tapered so that with age, if it swells it will not become unstable. 
     Many items detailed above are optional, and can be omitted. Many can be changed in size, made of different material, made of a different shape, connected or associated in a different manner, made integrally or in sections, or varied in other ways without departing from the invention in its broader aspects. These items are offered by way of illustration only and not as a limitation. 
     Since the only difference between sonic and ultrasonic is the frequency range, the sonic and ultrasonic washing actions can be combined by the substitution of a wide range waveform generator/power amplifier instead of the ultrasonic generator and the sound generator/power amplifier, and substitution of a wide range underwater transducer instead of the underwater speaker and the ultrasonic vibrator and plate. 
     Several alternate scrubbing actions and means of generating those actions have been described. Others too numerous to include are obvious to one versed in the art. Other examples include a bag laying on motion device, rocking, kicking or shoving by any means, motion imparted from a vibrating object inside the bag, motion imparted from a vibrating device outside the bag, any alternating deformation of the bag, injection and extraction of fluid into and out from the bag, friction with sides, friction with items, circulating fluid inside the bag and circulating air bubbles within the fluid. A set of multiple agitating methods could be used simultaneously, or alternatingly. 
     Many variations on agitation have been presented. Many more are obvious to one versed in the art. A few examples will illustrate the variety. Where agitation is accomplished by reversing the flow of water in the bag, a reversible pump could be used for reversing the flow of water. Conventional automatically operated valves could be used for reversing the flow of water. A manifold with water jets in at least two directions could be used for reversing the flow of water. Each of the directions could be used independently. 
     Many variations on built in water treatment devices have been presented. Many more are obvious to one versed in the art. A few examples will illustrate the variety. An ion exchange water treating cartridge, could be installed for those with hard water. Rapid vibration of the fluid which results in cavitation, has been presented as a means of agitation. Others versed in the art might argue that it is a means of water treatment. Many physical phenomena result in the improvement of cleaning properties of water. The intent is to include as many as are obvious to one versed in the art. The inclusion of water treatment, whatever form it may take, is an object of the invention. 
     While particular embodiments of the present invention have been shown and described, it will be obvious to those skilled in the art that changes and modifications may be made without departing from the invention in its broader aspects. For example, where water is mentioned throughout the descriptions, it is obvious that any cleaning solution may be substituted, where textiles or clothes are mentioned throughout the descriptions, other objects could be washed including such diverse items as farm produce or the removal of clay from placer gold. Therefore, the aim in the appended claims is to cover all such changes and modifications as fall within the true spirit and scope of the invention. The matter set forth in the foregoing description and accompanying drawings is offered by way of illustration only and not as a limitation. The actual scope of the invention is intended to be defined in the following claims when viewed in their proper perspective based on the prior art.
