Description

Technical Field of the Present Invention

The present invention relates to a washing machine for applying wet, dry, physical or chemical treatments onto materials, comprising a shaft positioned horizontally or having an angle with the horizontal axis, a perforated drum turn around a bearing system, a water chamber outside the drum wherein the water coming out of the drum is collected, moving parts placed inside or outside the drum in order to aid the working of the machine and/or increase the performance of the machine and/or provide economy of resources used by the washing machine such as water, energy, chemicals and time, motors, mechanical, pneumatic, electrical and electronic systems placed inside or outside the drum that are connected to said moving parts for moving said moving parts in a controlled manner and auxiliary equipment required by said systems and wherein energy sources such as electricity, pressurized air and steam is provided on the drum and areas where the contact of devices, instruments and equipment used in said systems placed outside of the drum in fully or partially water-free zones. Said washing machine may comprise a front load drum having shaft and bearings in the rear or a drum having bearings on both sides that can be loaded from the cylindrical surface. In order to not cause confusion, a front loading drum having a bearing on one circular surface and a loading opening on the other circular surface is depicted in the description and the terms front and rear are used to describe these two circular faces of the drum. It should be understood that, in the case of a drum having two shafts and a loading opening on its cylindrical surface, the terms front and rear refer to the two circular surfaces of the drum where the shafts are located.

Background of the Present Invention

The machines described by this invention are generally referred to as "washing machines" because they are commonly used in households for washing laundry using water and chemicals such as detergent, bleach and fabric softener. However, they can be used for a variety of purposes and can have different capacities. Machines of this kind having a capacity between 4 and 16 kg are used in households and those having a capacity between 16 and 500 kg are used in industry. These appliances are most widely used in washing, dry cleaning, piece dyeing and stone washing. Even though they are mostly used for wet treatments, they can also be used for dry treatments in special applications such as stoning or sanding. Another appliance that is similar to washing machines from a technical standpoint and that is front-loading and has a perforated drum is a drying machine. There are 3-4 carrying ribs on the perforated cylindrical surface of the drum to ensure that the material moves along with the rotation of the drum. The physical effect is realized by this movement caused by the rotation of the drum.
Document WO 2017/206922 A1 details a drum washing machine with an inner cylinder and an outer cylinder, equipped with a drainage device. It further includes an annular isolating passage between the cylinders, a non-porous structure in certain areas of the inner cylinder, and specific arrangements for water inlet and outlet holes. The design also incorporates seals between the annular isolation channel and the cylinders, with a particular focus on the placement and structure of these seals. Additionally, the machine includes a partition that doubles as a washer door, and a shower device within the annular isolation channel. A guiding structure on the inner cylinder's wall and a specific washing method utilizing the annular isolation channel are also described.

Summary of the Present Invention

The invention proposes machines that are generally known as perforated-drum washing machines. The machines are designed to provide mechanical and/or chemical treatments in wet, and in some situations dry, conditions to the materials loaded into the drum. Generally, the physical effect provided by a drum rotating in a water tank to materials inside the drum such as mixing, dropping, rotating and rubbing aid in increasing the effect of the chemicals added to the water. Said machines can be produced for many purposes, starting from "small scale" machines having a drum volume of 40-100 L. for household use and can go all the way up to industrial scale machines having drum volumes up to 5000 L. While they are generally referred to as washing machines, they are used as dry cleaning machines in applications where chemical solutions are used instead of water, as washing machines in household and industrial applications and can also be used to wash materials other than laundry in textile applications, mechanical applications such as stone washing to abrade of textiles and chemical applications such as dyeing. In washing machines that are defined as laundry machines, the perforated drum is placed in a water tank that is fully sealed against water leakage from the door or around the drum shaft. While the drum is defined to be fully sealed, it is important to note that there are inlets to and outlets from the tank such as water and solid or liquid chemicals, steam inlets to the drum, a discharge system for waste water, an overflow system in case the water level in the drum rises excessively, excess steam and water vapor outlets.
The present invention comprises systems that are suitable for adapting to any type of washing machine. Therefore, the phrase "washing machine" indicates all machines providing wet, dry, chemical or mechanical treatments in a perforated drum. However, the description and figures depict a medium-scale industrial machine in order to exemplify the applications. Unless specified otherwise, the figures depict a drum having a diameter of approximately 1600 mm and a depth of approximately 600 mm. Based on these measurements, a cylindrical drum would have a volume of 1200 L. For example depicting small scale machines for household use, the drum has a diameter of approximately 575 mm and a depth of approximately 4500 mm, having a gross volume of 110 L. and net volume of 100 L. the difference between gross and net volumes is a feature of the invention and will be explained below.
The aim of the invention is to increase the physical effect provided by the rotation of the drum and decrease the physical effect caused by the uneven weight distribution during the spin cycle. For this purpose, moving parts that are moving inside and outside the drum have been added to the drum. Moving parts inside the drum increase the physical effect required by the treatment while the moving parts outside the drum prevent the oscillations and vibrations caused by the unbalanced weight distribution during the spin cycle. In this manner, the perforated drum of the washing machine is no longer just a cylindrically shaped canister, but gains the characteristics of a functional machine by itself.
The addition of dynamic parts inside and outside the drum also requires drive sources and drive transfer means (mechanical systems) to be added as well. It is clear that electrical and electronic systems are required to drive and control the mechanical systems. It can be deduced that, even though it is normally possible for said systems to apply on conventional washing machines to operate between the inner and outer drum, i.e. in water, applications of this kind have associated problems. To overcome these problems, it must be ensured that areas outside the drum where said systems are situated are as water-free zones (100) as possible.
While the presence of electrical, electronic and pneumatic systems required for mechanical systems are not a mechanical requirement but this invention will also allow application of electrical or electronic systems together with mechanical dynamic systems to drive and control.
Moving parts inside the drum create physical effects in addition to those created by the rotation of the drum and are used to increase the physical and chemical performance inside the drum. Said moving parts are placed inside the drum, which increase the desired physical effects on the materials placed within for treatments such as washing, dyeing, stoning, polishing and brushing.
The proposed system of the invention provides rubbing in washing machines, brushing in machines where hard materials such as dust mats are washed, and abrading of textiles without the need to use environmentally harmful pumice stone. The system proposed by the invention makes possible the addition of parts that are capable of rotation, oscillation, vibration or eccentric movements and axial movements in horizontal and vertical directions when driven by a motor/movement system.
All these are possible by applying Poly-Ribs/protrusions/sheet bar/grate bars (525) inside of the cylindrical drum inner surface (104-n). Protrusions on the perforated surface hold washing materials away from drum surface to keep holes open and also create water channels to flow water from any area of the drum till to perforated area at the end of the washing and during the extraction. This means from now on no more need to spread the perforations on the whole drum surface for draining efficiency. So even if the holes were only within a certain area of the drum surface, the water in other regions was able to flow through the channels formed under the protrusions and reach the holes quickly. This allows the drum holes to be located in a limited area on the drum surface.
If the washing machine has an extraction feature, the addition of moving parts outside the drum provides a new solution to the problem of oscillations and vibrations caused by unbalanced load distribution during the spinning extraction cycle. In this method, moving parts can be moved in such a way to provide a counter weight against to the unbalanced load distributed in the drum. In this manner, the loss of balance during the spin cycle can be compensated consistently. The use of a known, sensitive system that is in use for providing balance to the drum during the spin cycle allows freedom from the springs attaching the drum to the chassis, the suspension systems and the weights attached to the drum chassis that were previously deemed necessary to use.
The moving parts inside the drum aid in the operation of the machine and improve the performance of the treatments done within as well as savings the use of resources such as water, energy, chemicals and time.
As electricity connected with the drum, it will become possible to mount all types of electrical and electronic devices, systems and sensors onto the drum. Electrical connection of the drum can be realized by any method known in the art as well as application of the systems of the invention as disclosed below. In this manner, sensors directed to getting desired information from the materials undergoing treatment in the drum and control systems for evaluating the measurements and interfering when necessary can be mounted onto the drum. The new system will facilitate access to the external surface of the electricity connected drum, making it easier for service and maintenance.
Supplying electricity and air to the drum makes it possible for all kinds of electrical and pneumatic systems to be mounted onto the drum. Aside from movement systems, devices serving particular purposes, such as valves and pistons will be functionally usable on the drum. In this manner, in the embodiments disclosed herein, it will be possible to cut off draining water from the inner drum to the outer water chamber by a valve. As the water filled into the drum will remain only inside the drum after the valve is closed, the water and chemicals added to the drum are fully used in an efficient manner therein. This means that the point reached in water and chemical savings is the highest possible level.
In addition, supplying electricity to the drum allows electrical water heaters to be mounted onto the drum for heating the water in the drum and keeping the water temperature constant directly therein.
Monitoring the process within the drum is especially very important for certain treatment processes applied in industrial type machines. It is necessary to observe the movements, conditions and changes in the material in the drum through the glass in the door used to close the entrance of the drum. However, as the inside of the drum is dark, the lighting from the door glass only illuminates a limited area. Whereas if the inside of the drum is illuminated by lighting elements mounted on the surface of the drum, a wider area can be illuminated.
It is inescapable that the motor(s), movement transfer systems, mechanical, electrical and electronic systems required for the operation of the dynamic, mechanical parts that will be mounted onto the drum and all or some of the control systems dedicated to these systems be placed immediately outside of and in communication with the drum. This means that in conventional machines where a water tank full of water is present outside the inner drum, some of said systems need to be positioned and operate in the water tank in contact with water.
According to the characteristics of the process in the drum, the water therein also contain added chemicals, insoluble solid particles and water soluble substances transferred to the water from the processed material inside the drum. It is inescapable that dynamic systems inside the water tank come in contact with the water containing chemicals and insoluble solid particles and that their operation be hindered due to the water. Precautions can be taken to ensure that dynamic systems inside the tank can operate without being affected by water and the chemical and physical substances in water. An exemplary application relating to this is a potato peeler having an abrasive roller. However, the main problem that needs to be solved is ensuring the smooth operation of motors, mechanical, pneumatic, electrical and electronic systems and moving parts in said liquid rich with chemicals and solid materials. Movement transfer systems such as belts, pulleys, bearings and gears for transferring movement from the motors mounted outside the drum to the dynamic systems inside the drum can be affected by solid materials that can be found in the washing water, such as thread, fabric, fuzz metal buttons, etc. The gears operating outside the drum in washing water may get stuck because they get tangled with the threads that have come off from the textiles. Especially in industrial applications, as the use of highly acidic or basic bleaching substances leads to corrosive conditions, the use of devices and materials not produced from stainless materials is undesirable. In this case, contact of mechanical and electrical dynamic systems in the tank with water can be prevented by the application of the saving system described in EP2229475 . Even if a water-free zone is provided in the volume between the water tank and the inner drum, a sealed volume formed by noncorrosive materials that is insulated from other parts of the tank that will not be affected by high temperature water, corrosive chemicals and steam need to be provided for said devices. The present invention proposes solutions for preventing contact between the liquid in the drum and the movement system on the drum in a practical and economic manner so that the dynamic system operates smoothly.
If a portion of the water tank can be water-free completely and permanently, it is understood that this part is practically not functioning. For example, if water does not reach up to the drum shaft within the tank, then use of conventional shaft sealing systems, such as sealing rings and felts, between the tank and the drum shaft are not necessary. In other words, if a part of the tank can be cleared of water, it is possible to eliminate said part. Elimination of a part of the tank means that said section of the drum will be taken out of the tank. Commonly, the part of the washing machine called as water tank or outer drum is mainly a part that is filled with water and that contains the inner drum. The water tank carries the water inside the drum. When the drum is not rotating the water levels inside the drum and the tank are equalized. In the proposed system water is not filled up to the level of the drum, therefore it would not be suitable to call this part as water tank. For this reason, a tank not fully surrounding the drum or not filled up to the level of the drum will be referred to as a water chamber (500). The water chamber is a chamber that surrounds only the perforated portion of the drum to collect and flow water away. That means all non-perforated parts of the drum are outside. All non-perforated external surfaces of the drum are free of water, meaning they are dry.
The washing machines (50) with horizontal drum that are widely used comprise a perforated drum (104) that is mounted inside a water tank by a drum shaft (103) and a drum shaft bearing (102). Before the details of the invention are disclosed, it is to be noted that the washing machines related to the present invention can be of two different types: household washing machines (57) and industrial washing machines (51). Both can have two different structures: front loading (58) and side loading (59). While washing machines designed for household or small-scale commercial use that can be produced by mass production techniques and washing machines for industry which are designed specifically for a given application are both referred to as "washing machines", there are significant differences between the two in terms of design and operating conditions.
The most important difference is the difference in size. Household washing machines (57) that are designed for individual use having a drum diameter up to 600 mm and defined as "small scale", commercial washing machines (56) that are designed for laundromats. Commercial and industrial laundries uses industrial washing machines (51) having a diameter between 600 and 1000 mm and defined as "medium scale". Industrial washing machines (51) designed for industrial use having a diameter between 1000 and 2000 mm and defined as "large scale" all provide treatment applications to materials having essentially the same features. When textiles undergo treatments in industrial washing machines, they are subjected to much greater physical effects than in household washing machines (57).
As there is no limit on the outer size of industrial washing machines, any and all sizes required by the system of the invention may be applicable without limit. However, the outer sizes of household washing machines (57) are fixed. Due to these international standards restrictions, it may not be possible to utilize some feature of the system of the invention in household washing machines (57).
Some measures to be applied in perforated drum washing machines (50) are changed in proportion with the size of the machine; however, some of them do not. The diameters of drum perforations/holes (105) of drums (104) having a drum diameter of 400 mm or 2000 mm are kept below a certain limit as technical means allow. As it is known that the smaller the size of drum perforations/holes (105), the less harm is done to the textile, so only technical and economic considerations are taken into account when determining the diameter of the holes. Drum perforations/holes (105) can have a maximum size of 5-6 mm. As the thickness of the cylindrical perforated drum sheet (106) increases with increasing drum (104) size, the minimum size of drum perforations/holes (105) is limited by production techniques. It is not possible to scale up a 5 mm drum perforations/holes (105) of a 400 mm drum (104) to 25 mm for a drum having 5 times the diameter. The reason for this is that the textiles undergoing treatment in both drums have the same features with same limitations. As the size of the holes increases, the sharp edges of the holes cause more damage to the textiles. On the other hand if drum size is increased mechanical effect is also increased, meaning the holes in the large diameter drum are more harmful than the same size holes of the smaller drum. However, the size of drum lifter ribs (107) rotating along with the laundry inside the drum should be changed in proportion with the size of the drum. As the loading capacity of the drum (104) increases with drum volume, the measurements of drum lifter ribs (107) are generally proportional to the diameter of the drum. It is obvious that ribs used for a small drum will not be able to fulfill their function in a drum having a diameter of 1500-2000 mm. While the ribs that are used in the drums of industrial washing machines (51) fulfill the function of rotating the materials along with the drum, they also cause a problem. The physical endurance of the textiles carried by generally triangular prism shaped drum lifter ribs (107) are similar to that of the textiles washed by household washing machines (57). However, tens of kilograms of textile materials on a sheet that is stretched between high ribs in a manner where there is empty space below, like a tent on the protrusions (531), will create forces in the magnitude of double digit tons during the spin cycle, due to the centrifugal forces that are 400 times greater than gravity force. As it is not possible for a sheet that is stretched between high ribs in a manner where there is empty space below to carry that much weight, it is unavoidable that it will tear or deform by stretching. For this reason, the size of drum lifter ribs (107) of industrial textile washing machines (52) must be optimized very carefully. In spite of this, the spin cycle speed of industrial textile washing machines (52) must be limited. Limiting the spin cycle speed causes the textile to remain wetter than necessary which leads to longer drying times and energy consumption during the drying process that is much higher than the energy consumption during the spin cycle. Using dynamic systems in the drums will eliminate this problem as well as the requirement that drum lifter ribs be stationary. During washing, drum lifter ribs can change their sizes as required and when the spin cycle starts, their heights can be decreased. This change in the sizes of the ribs can be realized by a motor to move parts on the drum (130) or a pneumatic system to move parts on the drum (131) to move parts that are mounted on the drum.
It is not preferable to add steam directly to the washing water in industrial washing machines (51) during heating. When steam is directly added to water, the amount of steam to be added is dependent on the initial water temperature and the desired water temperature. When steam is mixed with water, it condenses into water, which leads to a change in the amount of water in the drum. This is undesirable, especially for processes where the ratio of chemicals and water is important. Especially for processes such as dyeing where all conditions have to be controlled in industrial parts dyeing machine (53), a change in the amount of water will lead to a lot of issues. Therefore, indirect heating by heat exchangers are used in industrial parts dyeing machines (53) used for these types of processes, even though they are more costly. Another disadvantage of mixing steam directly into water is the danger of foreign materials entering from the steam system and fixtures carrying with steam. Steam fixtures need to be constantly kept clean, otherwise foreign materials entering along with steam may cause problems with the quality of the material being processed. Steam obtained using a steam boiler or steam generator also has an economic disadvantage. The whole boiler with full of steam needs to be heated even when a small amount of steam is needed. This process takes a long time and produces more steam than is needed which causes unnecessary energy consumption that is costly.
Non-perforated external surfaces of the drum on the outside of water chambers (500) allow the drum to be directly heated by furnace. The drum is in direct contact with the washing water and the materials being treated therein. Therefore, when the drum is heated from the outside, the washing water will be heated indirectly. This method has many advantageous consequences. This technique is one of the well-known heating methods since humans started to control and use fire. We still cook and heat meals in the saucepan on the fire cooker. With a burner placed under the drum, washing water heating in the machine is looks very simple and practical. It is also very economical; there will be no need to invest in a steam boiler/generator and all expensive steam pipeline system together with all related parts and equipment. On the other hand if there is no further need for steam, the leftover steam in the steam boiler will condense into water, which leads to an energy loss, especially in plants that are not operating continuously. On the other hand, if the drum is heated directly by any fuel in the required amount, only the necessary amount of energy is consumed and maximum efficiency is obtained. In the proposed invention, water in the drum is heated directly; therefore the need for water fixtures containing heat exchangers and pumps is eliminated. As a result, there will be no need for a costly investment and a system comprising elements requiring maintenance such as heat exchangers, pumps, fitting parts, valves and filters is eliminated. In addition, heat losses related to the heat exchanger and related fixtures are also eliminated.
While details such as household drum holes/perforations (605) and the space between drum and water tank opening at household drum entrance/inlet opening (608) of household washing machines (57) are designed with the fact that socks will be washed in the machine in mind, it must also be taken into account thousands of socks will be dyed together in the drum of an industrial parts dyeing machine (53) having a diameter 5 times greater and drum capacity 25 times greater when designing the space at drum entrance/inlet opening (108).
Describing all machines under the title washing machines regardless of their different capacities may lead to some confusion while disclosing the invention. While some embodiments of the invention can be applied to household washing machines (57), commercial washing machines (56) and industrial washing machines (51), others may only be applied to one type of washing machines. The main targets of the invention are first and foremost commercial washing machines (56) and industrial washing machines (51). For this reason, the descriptions below are given for medium and large capacity machines. Sections specifically related to household washing machines (57) and industrial washing machines (51) must be evaluated by taking this into account.
Industrial washing machines (51) do not solely refer to industrial textile washing machines (52). Machines having similar features are used for many different washing treatments and these machines are also defined as washing machines. Household washing machines (57) and commercial washing machines (56) are generally used for washing laundry. However, aside from industrial textile washing machines (52), large capacity industrial washing machines (51) also comprise industrial parts dyeing machines (53), industrial stone washing machines (54), final washing of the textile products of the textile manufacturing, rubber-covered dust mat washing machines and industrial heavy material (such as carpets) washing machines (55). While they are similar in terms of looks and basic structure, they have very different structural features.
The present invention comprises many features having a technical advantage that are based on the system where a section of the drum is taken out of the water tank and/or water-free zones are formed on the outer surface of the drum using the Poly-Ribs Eco-Drum technique that explained by EP2229475 . However, it has become necessary to organize the disclosure to cover all the features, because they have features that complete each other in application, one feature makes it possible for another feature to be used, using the features together lead to advantages greater than their individual advantages and the details of their applications can be described by embodiments that are realized by using multiple features together. One of the principles and preferred purposes of the invention is the presence of moving parts in the balance system (300) inside and/or outside the drum. Providing the conditions wherein moving parts (200) that can be moved in a controlled manner can be mounted onto the drum, what the moving parts may be, the advantages brought about by the moving parts and the operations possible with these machines are organized and described under the headings below.
The most important inventive step of the invention is to directly connect electrical energy to the drum and to move all moving parts in the drum with electric motors.
We call the water-filled part surrounding the inner drum a "water tank or an outer drum", as well sometimes a water tub. Water tank and outer drum are good definition for water fill closed container. But if the chamber at the outside of the perforated inner drum is only functioning to collect drain water come through inner drum perforations, water chamber will be more suitable to define. In this description, the outer drum, water tank, water drum is used to describe the water container in conventional washing machines. In our system the outer chamber only for collecting water likes a chamber. So it is more appropriate to refer to this part as water chamber.

Summary

The system described in EP2229475 aimed to save water by collecting all the water exist in the outer drum into the drum. For this purpose, the presence of water in the outer drum or even completely emptied can be controlled. For this purpose, the amount of water contained in the outer drum or even the complete discharge of the outer drum was controllable. In fact, if there is no water in the outer drum in any circumstances, what is the reason for the outer drum existence? The outer drum is no longer outside the drum, i.e. there is no known water tank surrounding the drum. It is enough to cover small part of the outer surface of the drum which water draining from the drum by the collection chamber to collect water from the drum. The drums being largely out of the water tank open the door to many new applications in the design of the washing machine. Thus, mechanical moving systems can be mounted inside and outside of the drum. Motors that provide these mechanical moving systems to operate can be mounted directly outside the drum. The electrical energy that enables the motors to drive said mechanical moving parts can be directly connected to the drum. In addition, various sensors on the drum, pressurized air systems, liquid or gas-driven equipment, liquid or gas transfer connections required for these systems can be provided. In a sense, the drum was gain freedom from coming out through outer drum. Until now, the rotating perforated cylindrical part that mounted in a water tank is called drum. After that, it will be possible to call this piece as "free-drum" and from now on, the free-drum itself can be defined as a machine.

1- Limiting the drain water from drum (104) at a steady flowrate and at pump capacity is described below.

It is possible control the volume and amount of water exist at the outside of the drum (104) using the Eco-Drum system (61) described in EP3252207 . Protrusions on cylindrical drum surface (261) placed around drum perforations on cylindrical perforated drum sheet (106) of the Poly-Rib system (60) described in the EP2229475 may prevent the materials undergoing treatment from reaching and fully or partially blocking drum perforations/holes (105). The Eco-Drum system (61) describes evacuation of the water in water chamber (500) by draining water from the free-drum (104) where the quantities and/or dimensions of holes are calculated or reduced compared to conventional drums with a limited flowrate and being pumped back into free-drum (104) by a circulation pump (112) having a larger pumping capacity that the flowrate of the water draining form drum (104). It can be deduced from the description that this systems also provides savings of water, chemicals and energy in the washing machine (50). Poly-Rib system (60) describes a system where protrusions placed on the surface of free-drum (104) prevent the laundry from fully blocking drum perforations/holes (105). The purpose of said protrusive cylindrical drum surface (261) is to hold the laundry away from drum surface and preventing the laundry from reaching drum perforations/holes (105) as much as possible. In conventional drums, while the number and size of drain holes is large, most of them are blocked by the laundry being washed and the actual discharge of water is much less than the drain flow capacity of the holes. On the other hand, even though the number of drum perforations/holes (105) is reduced more than ten times in the Poly-Rib system (60), most of the holes are kept unblocked whereby protrusions on cylindrical drum surface (261) so the discharge capacity of the holes is mostly unchanged. By preventing the blockage of drum perforations/holes (105) that are positioned in the area of influence of protrusions on cylindrical drum surface (261) by the material undergoing treatment, water flowrate from drum perforations/holes (105), which is limited compared to that of conventional drums provides under controlled water draining that is continuous but limited based on the pump flow rate capacity. The purpose of protrusions on cylindrical drum surface (261) is to prevent the laundry from reaching drum perforations/holes (105) and restrict the outflow of water from said drum perforations/holes (105). If the capacity of said pump is higher than the highest possible flowrate of water being discharged into water chamber (500), it will not be possible for the water level in water chamber (500) to rise high enough to reach free-drum (104). Therefore, the drum outer surface (104-s) is prevented from coming into contact with water. The Eco-Drum system (61) plays a key role in providing water-free zones (100) on the surface of free-drum (104) and taking drum (104) partially out of water chamber (500). When protrusions on cylindrical drum surface (261) are designed to prevent the materials from reaching drum perforations/holes (105), they will also prevent materials from reaching the surface of free-drum (104). In certain embodiments of the invention, it may not be necessary to employ protrusions on cylindrical drum surface (261) to prevent the materials from reaching drum perforations/holes (105). The individual shape of the surface of free-drum (104) or other parts having different purposes (234, 240) can function as barriers between the materials and drum inner surface (1 04-n) without any need for protrusions on cylindrical drum surface (261) as described in EP2229475 and prevent the materials/laundry from reaching and blocking said drum perforations/holes (105). In this case, the water flowing from the materials being washed in free-drum (104) can pass between said parts and reach said drum perforations/holes (105) without encountering any obstacles. Because drum perforations/holes (105) are not blocked, as long as enough water flows from the materials, the flowrate of water leaving free-drum (104) will be stable and acceptable with respect to the pumping capacity. The shape and height of and the distance between protrusions (261) can be designed so that the materials go into recess between protrusions on cylindrical drum surface (262) do not reach the surface of drum (104). It is important to take into consideration the physical characteristics of the textile being washed. When said protrusions (261, 622) or parts (234, 240) that are placed onto the surface of drum (104) prevent materials from going into the area there between, water channels (524, 621) are formed between the protrusions. When there are no protrusions (261, 622) or parts (234, 240) to form water channels (524, 621) on the surface of free-drum (104), said conically molded roller housing water channel (241) may be designed and applied. The water flowing in water channels without encountering any obstacles can reach the area where molded roller housing water discharge holes (235) are located, and pass through drum perforations/holes (105) that are unblocked thanks to protruding structures (261, 234, 240) around and exit free-drum (104). If Poly-Ribs/protrusions/sheet bar/grate bars (525) are placed side by side on the drum inner surface (104-n) means also Poly-Channels exist in between said Poly-Ribs functioning water channels to flow water from no perforated areas to drain perforations. By means of water channels/Poly-Channels (524) only the area where drum perforations/holes (105) are located will be a drum wet-outer surface (104-w).

2- Taking the drum out of water tank/outer drum (101) and water chambers (500) is described below.

The difference of the disclosed system from conventional washing machine (50) is providing water-free zones (100) no water at least some outside surface parts of the free-drum (104).
In the disclosed washing machines system, perforated free-drum (104) in a water vessel fulfills the function of water collection in the form of a sink, bowl, tub or basin. As known, all these vessels are partially open water containers. According to the present invention, defined vessels functioning only to collect the water exiting from the drum will be defined as water chamber (500). In this way, the function of the water chamber is no different than sink used to wash hands every day. For example a chamber where water chamber drain outlet (503) has a good draining flow capacity to always empty out the water flowing into the chamber and therefore never overflow. In other words, the vessel ensuring that water draining from the free-drum (104) reaches water chamber drain outlet (503) without accumulation is referred to as water chamber (500). In some washing conditions, useful water in the drum has to be decreased for a short time. If it is desired to decrease water in the drum, to collect said portion of the water discharged from the free-drum (104), a water accumulation chamber (502) have to be designed having a volume, shape and depth wherein the highest level of water never reaches to the drum.
In conventional washing machines (50) water tank/outer drum (101) wherein free-drum (104) is made up of one piece as will be understood from the description of the tank. It is necessary to provide water chambers (500) in areas where the water draining through perforations of the drum in order to ensure that movement system that needs to be placed outside of the drum is positioned outside of said water chambers (500). In this case, the drum is not in a water tank/outer drum (101), described water chamber (500) surrounds only areas where water draining zones such as drum perforations/holes (105) and the gap around drum opening between drum and front panel (114) around drum entrance/inlet opening (108) will be present. There will be some other advantages to changing the definition "in washing machines free-drum (104) is placed inside a water tank/outer drum (101)". As is known, for high speed spinning extra weights are added on outer drum. Water tank/outer drum (101) and weights added onto the outer drum are used to suppress the oscillations and vibrations caused by the imbalance during the high spin cycle as much as possible. Therefore it is particularly preferable that water tank/outer drum (101) is heavy. While water tank/outer drum (101) and the weights decrease the oscillations or vibrations motion of water tank/outer drum (101) trying to spin at high speeds with unbalanced weights, they also create additional loads and force to drum shaft (103) and drum shaft bearings (102). But if the problem of imbalance of the drum is solved by balancing the drum, the need for extra weights on water tank/outer drum (101) is eliminated and it will be possible to make water tank/outer drum (101) as light as possible and the mechanical structure of the shaft and bearing carrying the drum can be simplified. In a balancing system, the total weight of the rotating object to be balanced is important. In some of the conventional applications, free-drum (104) is carried by a water tank/outer drum (101) chassis having a flexible structure. The principle that the flexible mass used as a tool to suppress oscillations and vibrations is systems other than the springs connecting the flexible drum chassis to fixed chassis (111) must be as heavy as possible will have the opposite effect in a machine having a balancing system. For balancing the drum first of all we have to determine the magnitude and position of the existing imbalance force by monitoring the drum system using proper sensors. As water tank/outer drum (101) and all weights on water tank/outer drum (101) will be counted among the rotating weight to be balanced, they affect the monitoring sensitivity of the balancing operation. Also, the counter forces created the centrifugal force by the unbalanced load in free-drum (104) and the water tank/outer drum (101) where the counter load to suppress said force is attached may cause stretching in the mechanical parts of the machine. Therefore, as with drum shaft bearing, water tank/outer drum (101) and free-drum (104) need to have higher than necessary mechanical strength. For this reason, detaching all manner of parts, such as water chamber (500) and parts directly connected to drum aside from drum and attaching them directly to the fixed chassis side will increase the monitoring sensitivity of the balance system.

DETAILED DESCRIPTION OF THE PRESENT INVENTION

Preferred embodiments of the present invention are described below.

1- The descriptions commence with water-free zones (100) and presence of water-free zones (100) outside the drum via Figures 1-15

One of the objects of the invention is to provide dynamism and different functionalities to a drum (104) of a washing machine (50) wherein a cylindrical shape perforated drum (104) is made from a stainless sheet, and for some applications only some parts may be made from plastic. So inner drum (104) is very basic, important and indispensable part of the conventional washing machine but also it is one of the simplest parts. Moving parts (200) drive with motors to move parts on the drum (130) by using energy such as electricity, pressurized air and steam, under control with electric, electronic, control systems (900) placed inside and/or outside drum (104) provide said drum (104), which is now more important part of a washing machine, with many new and useful functions that were previously unavailable. The present invention effectively overcomes the disadvantages of the drum (104) being placed in a water tank/outer drum (101) full of water.
The question that the invention seeks to answer is how to prevent the presence of water in the regions of the movement transfer system (401) moving these moving parts outside drum (251) when there is enough water in the drum (104) and when the water in the drum is drained at the end of the washing and rinsing cycles and also during high speed extraction it is inevitable that the water leaving the drum from perforations and passes into the water tank/outer drum (101). The first solution to come to mind will be isolation.
On the regional isolated area in movement system (142) or isolated unit in movement system (143) basis, isolation is possible, but due to their restrictions the preferred method is to prevent the ingress of water into the areas where movements systems are located without isolation. In other words, to render areas required for movement system outside the drum (104) are water-free zones (100).
Drum (104), at least a part of the drum (104) taken out of the water tank/outer drum (101) and especially clearing water from areas where systems that are dangerous to be placed and operated in water are located has paved the way for many new useful possibilities and applications on the drum. Even though it is not necessary for the area where movement transfer system (401) is located to be free of water, it is preferable for the functionality and economy of the system.
In addition to being easier and more applicable than isolated areas in movement system (142) or isolated units in movement system (143), said method also makes it possible to use all kinds of mechanical, electric, electronic and control parts in movement systems (401) in the area between water chamber (500) for collecting water draining from the drum (104). In this manner, drum (104) is changed from a cylindrical perforated drum sheet (106) into a moving, dynamic and functional device, i.e. a machine by itself. It can be referred to as a machine, because even though the rotation of the drum stops, the systems on the drum can continue its operations which ensures that drum (104) remains functional.

2- Forming of water-free zones (100) in water chamber (500) by a circulation pump (112) is explained below via Figures 1,3-12, 14, 15.

The first step is to ensure that the limits and flow paths on water chamber (508) of water in water chamber (500) are determined, that the water remains in these areas and that the water level can be controlled. In other words, it is possible to turn areas on drum outer surface (104-s), where the presence of water is not required, into water-free zones (100).
To identify the water-free zones (100), means that there is no water inlet to the area which is partially constrained by the drum outer surface (104-s) which is referred to as water-free zones (100) of a part of the drum under all circumstances except in the case of an unintended fault, the system is out of control, despite all precautions and measures taken in the machine.
The areas that are always kept dry on drum outer surface (104-s) the drum are water-free zones (100).
Areas on drum outer surface (104-s) where water-free zone (100), i.e. the dry zone conditions cannot be obtained are areas where water drains from the drum. These areas can be determined as drum perforations/holes (105) part of drum inner surface (104-n) allowing water discharge from the drum and the gap around drum opening between drum and front panel (114) around drum entrance/inlet opening (108) that needs to be left gap around drum opening between drum and front panel (114) in-between drum (104) which is the rotating part and the fixed part unless additional precautions are taken.
In washing machines (50) known in the art, the water level in drum (104) is balanced out to the same level with the water level in water tank/outer drum (101) according to principles of communicating vessels. Water first fills up water tank/outer drum (101) and enters through perforations in to the drum (104) when water level reaches required quantities in the drum. In these washing machines, the main function of water tank/outer drum (101) is first to fill drum (104) with water and then discharge the water exiting the drum.
The task of the water chamber (500) is to ensure the flow of the water leaving the drum from the shortest flow path on water chamber (508) to the circulation line (113) or the water chamber discharge line (511-d). When the definition of the outer drum is redefined as "the function of water chamber (500) is to ensure that water exiting the drum flows into circulation line (113) or water chamber discharge line (511-d) via the shortest flow path on water chamber (508), a big step will be taken in terms of providing to explain this system. When we defined in this way, the outer tank is no different from a sink or a bathtub. For example, similar to a sink or bathtub where the water from the tap flow out from the drain in everyday use and the drain can be blocked to fill the sink with water and opening the drain after use so that the water can be drained.
Using this definition, there is no longer a need for an outer drum to be present outside of drum (104) of a washing machine (50). The function of outer drum, i.e. water chamber with the new shape (500), is not to fill the drum with water but to collect the water draining from the drum and direct it towards the water chamber drain outlet (503). Rather than a water tank/outer drum (101) wrap the drum completely, the water exiting drum (104) can be collected by water chamber(s) (500) placed only in areas where water discharge occurs.
It is possible to apply the systems proposed by the invention by turning areas outside those where the water exiting the drum flows into water chamber drain outlet (503) of water chamber (500) and areas where moving parts (200) are placed in water-free zones (100).
It is clear that in order to turn necessary areas on drum outer surface (104-s) into water-free zones (100) by simple water chamber barrier (511), there needs to be enough water in the chamber on the other side of chamber barriers to not pass through the barrier due to pressure. Going back to the sink example, in order to prevent water from overflowing, the sink needs to be sufficiently deep, the sides need to be steep and high and the water level in the sink needs to be below the overflow level. For this reason, water level outside drum (104) should not be high enough to reach the drum and water sensitive systems connected to said drum (300, 400, 900). In other words, while a sufficient amount of water is present in drum (104), the water level in water chamber (500) should under no circumstances be high enough to reach drum (104). Because the water in water chamber (500) can be kept constant at the desired level using the Eco-Drum system (61), the volume and depth of water chamber (500) is irrelevant with respect to water consumption.
The systems according to the present invention prevent the water from passing into water-free zones (100) without need for using sealing elements such as gaskets or felts, even at the highest possible water level. Water build-up levels high enough to go over water chamber barrier (511) between areas containing water and water-free zones (100) and build-up of pressure enough to push water over should not be allowed. Structural water chamber barriers (511) are actually only barriers to direct water flow in order to keep the water in the desired area without overflowing.
To ensure that the areas required for the system outside the drum (104) are water-free zones (100), it was possible to implement the Eco-Drum system (61) as described in EP3252207 so that there was no water accumulated in the water chamber (500), outside the drum to reach the drum. According to the system explained in this document, the pumping flow rate is higher than draining flow from the drum (104) to the water chamber (500), will keep the water in the drum and keep at a desired level in the chamber that will prevent it from entering the water-free zones during the process requiring the presence of water in the drum. In other words to make sure that the water level stays low enough to prevent water from flowing into water-free zones using a circulation pump (112) having a pumping flowrate higher than the flowrate of the water flowing from drum (104) to water chamber (500), using the Eco-Drum system (61).
As long as the water exiting drum (104) is pumped back into said drum by a circulation pump (112), entry of water into water-free zones (100) will be prevented. However, depending on the treatment operation, it may be necessary to reduce the amount of water in the drum without discharging the water from the machine. In this case, circulation pump (112) will also need to be stopped. When water in drum (104) has to be reduced or discharged as much as possible, there is a need for a storage space to store this water in the machine. This storage tank may be a water accumulation chamber (502) or a water storage chamber (504) connected to said water chamber (500). Water accumulation chamber (502) or water storage chamber (504) can be used to store water for a treatment operation of the machine as well as transferring water from one treatment operation to another. When a water accumulation chamber (502) or a water storage chamber (504) is present, the water level inside the drum can be changed in a controlled manner during the treatment operation. In addition, in case of a malfunction, all the water in the drum can be transferred to the storage space (502, 504) to prevent water from overflowing from water chamber (500).
Even if a water chamber capable of storing all the water when it is out of drum (104) is not present in the machine, reaching the water level and pressure allowing water to go over simple water chamber barriers (511) in water chamber (500) and into water-free zones (100) or overflow from the machine must be prevented. To achieve this, the water level in water chamber (500) must be continually monitored to ensure it stays below the desired limits and water must be discharged through a water chamber overflow line (511 -o) if it goes above.
The logic here can be explained using an example from real life. If seawater filling a boat from a hole can be continuously pumped out of the boat using a pump having a flowrate higher than the inlet flowrate, then the boat will not sink. It the pump is stopped intermittently and the water level in the boat rises, if the pump is operated again before the water level becomes high enough to cause the boat to sink, the water can be discharged.
In order to achieve this, the water in water chamber (500) needs to be pumped back into drum (104) at a flowrate higher than the drain rate of water from drum (104) to water chamber (500) under any circumstances as described in Eco-Drum system (61).
When the pumping capacity of circulation pump (112) is always greater than the drain rate of water flowing from drum (104) to water chamber (500), water chamber (500) and water accumulation chamber (502) can be completely emptied by collecting all the water in said water chamber (500) in drum (104). It should be noted that circulation pump (112) having a flowrate higher than the flowrate of the water exiting the drum is necessary not only to ensure water-free zones outside the drum remain dry but also to ensure the efficiency and sustainability of the treatment operation in the drum and also for water savings.
The capacity of the pump used to empty water chamber (500) can be reduced by reducing the drain flow rate of water from the drum to the water tank.
For this reason, placing drum perforations/holes (105) in drum (104) at locations where they won't be blocked by the laundry material and reducing their number and diameter will allow circulation pump (112) required to drain the water in water chamber (500) or control the water level to have reasonable capacity and size and economic energy consumption. Reducing the number and/or size of drum perforations/holes (105) will make it possible to limit the flowrate of water exiting the tank as desired. However, it is also important to ensure that the flowrate of water exiting the tank is constant. Therefore, blockage of drum perforations/holes (105) designed to control water permeability by materials being treated in the drum must be prevented. In this case, drum perforations/holes (105) must be positioned so that the materials cannot reach and block them completely. To achieve this, either drum (104) must have a structure suited to preventing the materials from reaching drum perforations/holes (105), or drum perforations/holes (105) must be placed in the hollows between the protruding structures (261, 234, 240) placed on the surface of the drum or drum perforations/holes (105) must be placed in the effective area of the protrusions so that the materials cannot block most of the said drum perforations/holes (105). For drum (104) to have a structure suited to preventing the materials from reaching drum perforations/holes (105), the function of protruding structures (261, 234, 240) in drum (104) as described by the Poly-Rib system (60) must be fulfilled by other parts on drum (104) surface. For example, drum perforations/holes (105) positioned beneath or in the effective area of rollers (201) inside drum, fixed grindstone pieces (216) and similar parts can ensure that drum perforations/holes (105) are open to water flow.

3- The preparation of water-free zones (100) on and around the drum shaft (103) and drum rear circular base/shaft side (110) of drum (104) according to the present invention is explained below via Figures 1-4.

When it becomes possible to form water-free zones outside drum (104), the first area to be considered will be drum shaft (103) and its surrounding drum rear circular base/shaft side (110). As is known, in washing machines having a perforated drum (104) inside an outer drum, flow of water out from water tank/outer drum (101) is prevented by sealing elements such as felt or gasket placed between drum shaft (103) and the outer drum. When the need for said sealing system is eliminated, drum shaft (103), which is the point of connection between drum (104) and the outer drum, sealing system around shaft can be canceled. Shaft will become free and the simplest way to transfer energy or fluids to the drum. In conventional washing machines as known in the art, water tank/outer drum (101) and inner drum (104) need to move together, be a part of the same system, in short, be connected to each other due to the sealing elements used therein. Whereas if contact of water within the tank with the drum shaft is prevented using methods other than felt, there will be no need to use sealing elements around the drum shaft (103), inner drum (104) and water tank/outer drum (101) can be separated from each other. The separation of drum (104) and water tank/outer drum (101) allows for radical changes in washing machine design. When there is no need for drum shaft (103) felts, drum (104) can be removed from outer frame chassis (120) and moved along with drum chassis (529). Therefore water tank/outer drum (101) in the form of water chamber (500) and machine cover and drum door (118) connected to water tank/outer drum (101) become an independent chassis. This will especially provide ease or production and maintenance of large industrial washing machines (51).
Creating a water-free zones (100) starting from drum rear circular base/shaft side (110) where drum shaft (103) is connected to drum (104) towards the corner where drum rear circular base/shaft side (110) is connected to perforated cylindrical perforated drum sheet (106) will provide a suitable area to mount movement transfer systems (401) on drum outer surface (104-s).
When it is taken into account that there is constant water flow from drum perforations/holes (105) on perforated cylindrical perforated drum sheet (106) and the gap around drum opening between drum and front panel (114) around drum entrance/inlet opening (108), it becomes clear that the best place for placing moving parts (200) outside drum (104) and movement transfer systems (401) for providing movement thereto that will be mounted on the drum is drum rear circular base/shaft side (110). For this reason, it is preferable that drum rear sheet and drum shaft (103) and surrounding area are the first place to be cleared of water to provide water-free zones (100).

4- Water tanks according to the present invention, namely, water chamber (500), water chamber surrounding partially perforated cylindrical drum surface (501), water chamber surrounding around whole perforated cylindrical drum surface are explained below via Figures 5-9.

Water tank/outer drum (101) placed outside drum (104) in currently available horizontal washing machines serve the purpose of collecting water draining from the drum (104) as well as filling water into said drum. In order to limit water consumption, the distance between water tank/outer drum (101) and drum (104) is kept as small as possible. It is also important that the volume of water tank/outer drum (101) below drum (104) bottom level is as small as possible in terms of water consumption. On the other hand, as the water level in water tank/outer drum (101) is controllable using the Eco-Drum system (61) described in EP3252207 , the system of the present invention proposes a large storage volume under drum (104) where a certain amount of water may be collected, and all the water in the washing machine may be collected without coming into contact with drum (104) when necessary. As the water volume under drum (104) will be controlled by the system and can be drained by the pump, its size is irrelevant to the amount of water consumption. When the Eco-Drum system (61) is applied, on the section of drum (104) where drum perforations/holes (105) are located will become wet. If the perforated area is restricted by water barriers (122, 511); the overflow of water being discharged from drum (104) from this area can be prevented. In this embodiment, the areas outside water barriers (122) will be water-free zones (100). Additionally, it is not necessary for a structure that will only be used to collect water exiting drum (104) to fully envelop said drum (104). A water chamber (500) surrounding drum (104) only in the manner to collect water exiting said drum (104) as around perforated surface and around drum entrance. Until today, the main reason for the closed volume outside the drum to be referred to as water tank/outer drum (101) was that it was filled with water. However, in the system proposed by the present invention, the volume surrounding the drum should never be filled with water. Because these volumes are always empty and only serve the purpose of directing the water exiting the drum towards the discharge outlet, it is more appropriate to refer to said volumes as water chamber (500) instead of water tank/outer drum (101) to avoid confusion.
As water exits drum (104) from drum perforations/holes (105) and the gap around drum opening between drum and front panel (114) around drum entrance/inlet opening (108), it is possible to collect water exiting the drum by placing water chambers (500) at these areas if desired.

5- A water storage chamber (504) in communication with a water accumulation chamber (502) positioned in a water chamber (500) according to the present invention is explained below via Figures 2-7, 14,15.

In contrast to conventional washing machines (50), it will be beneficial for a system according to the present invention to comprise a water accumulation chamber (502) below the water chamber (500) which has the capacity to store partially or all the water in the drum (104) when necessary.
This storage volume may be in the form of a water accumulation chamber (502) directly inside water chamber (500) or it may be a separate volume as water storage chamber (504) in communication with a water chamber (500) with a water chamber-water storage chamber connection (507) serving the function of collecting and storing water from drum (104) when necessary.
It must be ensured that the water draining from the drum (104) flows directly to water accumulation chamber (502) or water storage chamber (504) without entering water-free zones (100) in water chamber (500). If water chamber (500) needs to not have water within in order to keep the whole required water in drum (104) constant, the water entering the water tank is continuously pumped back into said drum by circulation pump (112) as described with Eco-Drum system (61).
If the areas where movement transfer system (401) in water chamber (500) and required devices thereof are placed is desired to be kept water-free, then they need to be placed above the maximum water level that water accumulation chamber (502) can reach.

6- Methods of controlling the water level in water chamber (500) according to the present invention are explained below.

While the main functions of water accumulation chamber (502) and water storage chamber (504) are to keep water from the drum so that water chamber (500) does not overflow in case of an expected malfunction and by controlling water level in the water chamber (500) also be used to adjust the water level in the drum with circulation pump (112) control. They can also be used to change the amount of water in drum (104) and temporarily store the water required at a different stage of the treatment operation when necessary. Even if water accumulation chamber (502) is filled with all the water that can be used by the machine, it should be able to prevent water level from reaching up to overflow level.
One of the important aspects of the invention is defining the physical conditions, dimensions and depth of the boundaries of flow path on water chamber (508) on water chamber (500). The water chamber (500), which provides the appropriate size and conditions, allows the water draining from the drum to reach the water chamber drain outlet (503) by preventing it from flowing out of the flow path on water chamber (508) between the water chamber barriers (511).
Water flow paths/water ways are structures facilitating flow of water between two locations, wherein water does not go beyond their boundaries even though they are at least partially open. While pipes are closed systems, water channels are open from the top. Even though water ways are open, when they are designed and controlled carefully they can transfer water from one location to another. Water channels are water ways with defined boundaries. This is the basic principle applied on the outside of drum (104). While until today, water tanks/outer drums (101) wherein drums (104) rotate were closed systems, water chambers (500) proposed by the invention form of flow paths on water chamber (508) directing water exiting from drum (104) to the discharge outlet.

7- The case where water chamber (500) is a chamber surrounding whole wet parts of the drum, i.e. front and sides surfaces according to the present invention is explained below via Figures 3, 5-7.

The water drain from the drum is from the drum inlet opening gap around drum opening between drum and front panel (114), except the drum perforations/holes (105) in the cylindrical perforated drum sheet (106). The structure of the drum entrance/inlet opening (108) is different in household washing machines (57) and industrial washing machines (51). Household drum door (617) closing household drum entrance/inlet opening (608) of household washing machines is on household frame frontal sheet (618) of household outer frame (616) and there is also a flexible household drum door bellows (614) between the door and the outer drum to prevent water from leaking out of the outer drum. On the other hand, industrial washing machines do not have a door bellows and instead drum door (118) is connected to machine front panel (119) which is also the front sheet of the drum. In both types of washing machines, the water leaving drum opening (108, 608) reaches outer drum via the space between the outer drum and drum (104, 604).
As water exits drum (104) from around drum entrance/inlet opening (108) and from drum perforations/holes (105), the fluid communication between flow path on water chamber (508) and water-free zones (100) must be completely severed while the transfer of water from said drum opening and said drum holes is directed. Solutions other than the known method of forming a flow path on water chamber (508) in known conventional water tank/outer drum (101) by taking precautions may be suggested for directing the water exiting drum (104) from around drum entrance/inlet opening (108) and from drum perforations/holes (105) to water chamber (500). As the water in water chamber (500) will not under any circumstances be collected outside of water accumulation chamber (502) placed at the bottom of said water chamber (500), presence of water chamber barrier (511) for preventing water from leaving water flow path on water chamber (508) wherein water flows from drum (104) to water accumulation chamber (502) will facilitate formation of water-free zones (100).
Considering that movement transfer system (401) is concentrated on drum rear circular base/shaft side (110), taking this area out of water chamber (500) is the safest way to cut out fluid communication of water from the chamber with said movement transfer system (401).
When water chamber (500) for collecting the water leaving drum (104) is designed in a way to leave drum rear circular base/shaft side (110) outside, it will be a water chamber close whole wet parts of the drum surrounding drum front circular base/opening side (109) and perforated cylindrical perforated drum sheet (106) as exemplified in Figures In terms of design and appearance, said water chamber resembles a customary half water tank/outer drum (101) without a rear sheet. So from now on this water chamber surrounding whole wet parts of the drum will be referred to as a half water chamber (505)
Said half water chamber (505) must contain water chamber barrier (511) systems designed to prevent water flowing from drum (104) to water chamber (505) at the edge portion at drum rear circular base/shaft side (110) from leaving half water chamber (505).
As said half water chamber (505) is ended at the edge portion where perforated cylindrical perforated drum sheet (106) and drum rear circular base/shaft side (110) meet, the rear of the drum is outside the tank.

8- Water chamber around drum opening gap (506) at around the drum gap around drum opening between drum and front panel (114) around drum entrance/inlet opening (108) according to the present invention is explained below via Figures 8-11, 14, 15.

If a moving parts system (141) outside drum is present on drum front circular base/opening side (109), it would be advantageous for this section to be a water-free zone (100) as well. As balance system (300), which is one of the systems proposed by the invention, will be mounted on the front sheet or cylindrical surface at the front part of the drum, in drums having a balance system, drum front circular base/opening side (109) must have a water-free zone (100). It is possible to create the conditions for a water-free zone (100) on drum front circular base/opening side (109) in half water chamber (505) surrounding the gap around drum opening between drum and front panel (114) where drum entrance/inlet opening (108) and drum perforations/holes (105) are. However, as difficulty in providing service and the effects of steam will cause problems for the aforementioned reasons, taking drum front circular base/opening side (109) also out of water chamber (500) will be a good solution. Especially in cases where a balance system (300) is mounted on the front of drum (104), it would be very advantageous for drum front circular base/opening side (109) to be easily accessible for the smooth operation of the system and for providing maintenance and repair services. The system applied to drum rear circular base/shaft side (110) can be applied to different sections of drum (104). In this way, other sections of drum (104) can be taken out of water chamber (500). In other words, water chamber (500) may be in the form of water chamber surrounding only perforated cylindrical drum surface (501) applied only to necessary areas on drum (104) to collect water exiting said drum (104). To achieve this, a water chamber around drum opening gap (506) formed to surround drum gap around drum opening between drum and front panel (114) around drum entrance/inlet opening (108) can collect the water exiting from said drum opening and directing it to water chamber surrounding partially perforated cylindrical drum surface (501) or a water accumulation chamber (502) via a water chamber-water storage chamber connection (507) pipe connected below.
Dividing water chamber (500) into a water chamber around drum opening gap (506) for collecting water exiting from drum opening gap around drum opening between drum and front panel (114) and water chamber surrounding partially perforated cylindrical drum surface (501) for collecting water exiting drum perforations/holes (105) provides a practical solution to the problem of taking drum front circular base/opening side (109) out of water chamber (500) like drum rear circular base/shaft side (110). In this way, when the water chamber (500) is divided into two sections (501, 506), the area left between will be a water-free zone.
Using water chambers (500) mounted only onto areas where water exits the drum instead of a water tank surrounding the entire drum will both make it easier to provide service to the outside of the drum and save on materials and labor for producing said water tank and make the washing machine lighter.
As exemplified in Figures 8-11, 14, 15 water chamber around drum opening gap (506) positioned to surround drum opening gap around drum opening between drum and front panel (114) contains a water chamber-water storage chamber connection (507) below for transferring the water exiting drum (104) to a water collection or storage tank.
In conventional industrial washing machines (51), drum door (118) connected to water tank/outer drum (101) must be connected directly to the front sheet, namely machine front panel (119) of the machine along with water chamber around drum opening gap (506). In conventional washing machines, said machine front panel (119) also covers the front of water tank/outer drum (101). In the new system, the front sheet/machine front panel (119) is directly connected to fixed chassis (111) of the machine. In this way, communication of drum door (118) and water chamber around drum opening gap (506) with drum-perforated area-water chambers (500) for collecting water exiting drum holes will be completely severed. And in industrial washing machines (51), drum door (118) will be directly connected to outer frame chassis (120), in other words fixed chassis (111) of the machine.
As exemplified in Figures 14, 15 because household drum door (617) is on household outer frame (616) in household washing machines (57) there is a household drum door bellows (614) at the household drum entrance/inlet opening (608) covering the area between the drum and household drum door (617). However, as there is no need for the drum opening water chamber to be in the same system as the drum in the system proposed by the invention, household drum opening water chamber (615) may be on household outer frame (616), i.e. on the fixed chassis system. In this case there will be no need for bellows and it will be possible to connect household drum door (617) to household drum opening water chamber (615) in household washing machines (57) as with industrial washing machines (51).
If the machine to which a system as exemplified in Figures 10, 11 is applied is an industrial washing machine (51), it is possible for the exiting water to be pumped directly back into the drum by a drum opening water collection chamber circulation pump (528) connected to the household drum opening water chamber (615) outlet instead of connecting water chamber or other tanks.
As is known, in free standing washing machines, water tank/outer drum (101) is connected to fixed chassis by spring and suspension systems and water tank/outer drum (101) moves freely due to the imbalance during the spin cycle. In the case where a balance system (300) is also present in the washing machine according to the present invention, said machine can be a hard mounted machine. This means that no connection element can perform an elastic movement beyond stretching within the bounds of material tolerance in the machine including the chassis. In this case, even though drum (104), water chamber (500), outer frame of the machine (117) and drum door (118) are separately mounted to fixed chassis (111), they cannot move with respect to each other and so it will be possible to decrease the gap around drum opening between drum and front panel (114) between drum entrance/inlet opening (108) and drum door (118) and water chamber around drum opening gap (506) or drum (104) and water chamber (500) compared to free standing machines wherein all said parts are on the same chassis. As limiting the distance between drum (104) and drum door (118) will significantly decrease water leaking with the help of additional barrier systems, a small drum opening water collection chamber circulation pump (528) connected to water chamber around drum opening gap (506) will be able to pump the water exiting from drum opening gap around drum opening between drum and front panel (114) back into the drum.

9- Water chamber surrounding partially perforated cylindrical drum surface (501) surrounding the portion of the drum where drum holes are located according to the present invention is explained below via Figures 1, 9-15.

When a water chamber surrounding only perforated cylindrical drum surface (501) is placed in the area where drum perforations/holes (105) are located, the water exiting from said drum holes can be directed to circulation pump (112) pumping the water directly back to the drum or a water storage chamber (504) via a water chamber drain outlet (503). With this design, water tank/outer drum (101) that consisted of one piece until today will be divided into two or, necessary, more sections referred to as water chamber surrounding partially perforated cylindrical drum surface (501) as exemplified in Figures 2 and 8. Because a smaller water chamber surrounding partially perforated cylindrical drum surface (501) will be more practical and economic, it will be advantageous to use an embodiment comprising drum perforations in peripheral zone (509) placed in a peripheral perforated narrow zone (510) in this system. As exemplified in Figures 1, 9-15, peripheral perforated narrow zone (510) can be placed on one or more positions on the drum. In other words, having drum perforations in peripheral zone (509) only in the area(s) surrounded by water chamber surrounding partially perforated cylindrical drum surface (501) will be advantageous is many respects. In this manner, the cylindrical sheet of the drum will be a cylindrical drum sheet peripheral perforated narrow zone (510) wherein said drum perforations in peripheral zone (509) are placed in peripheral perforated narrow zone (510) will have the appearance of a cylindrical sheet without holes. Water chamber surrounding partially perforated cylindrical drum surface (501) for water exiting from drum holes can be placed around the middle, front or rear of cylindrical drum sheet perforated in the peripheral perforated narrow zone (510). In this case, as drum perforations in peripheral zone (509) will be only in this area, it must be ensured that the water in the drum flows towards this area. Having a drum sheet that is a Conical drum sheet perforated in the narrow belt zone (512) with a conical structure to ensure that said drum sheet is sloping towards the area where the holes are located will assist in the flow of water towards the area where the holes are located.
If drum holes in peripheral band zone (509) are distributed on the conical or cylindrical surface in groups in multiple peripheral perforated narrow zone (510), it will be required to utilize multiple drum-perforated area-water chambers (500).
A flow path on water chamber (508) may be formed by structural obstacles and barriers to prevent water from overflowing outside from between water chambers surrounding drum opening and drum holes and the drum. As exemplified in Figures 3, 5-9, overflow of the water flowing from drum (104) to water chambers surrounding around partially perforated cylindrical drum surface (501) from said water chamber limits can be blocked by a water chamber barrier (511) placed on water chamber surrounding partially perforated cylindrical drum surface (501) and corresponding external water barriers (122) placed on the drum. The function of the barriers on water chamber surrounding partially perforated cylindrical drum surface (501) is to prevent water at the bottom of the tank from overflowing into water-free zones (100) of water chamber surrounding partially perforated cylindrical drum surface (501) and overflowing out of water chamber surrounding partially perforated cylindrical drum surface (501). The function of external water barrier (122) placed on the drum is preventing water exiting the drum from overflowing past water chamber barrier (511) while being flung by the rotation of drum (104) during the spin cycle and wetting every surface of flow path on water chamber (508) in water chamber (500). Water barriers may be positioned in single lines opposite each other and side by side or they may have a multiple cascading structure in the form of successively positioned sets as exemplified in Figure 12B

10- Use of a discharge system to prevent steam/gas leaking from the water chambers according to the present invention is explained below via Figures 10, 11.

It has been mentioned above that by taking water-free zones (100) out of water tank/outer drum (101) or water chamber (500) devices placed in these areas (400-900) are protected from negative pressure effects caused by the steam generated due to the high water temperature in the drum. Also some of the washing processes need to inject harmful gas into the drum. We have to avoid also uncontrolled gas leakage from water chambers. However, as structural barriers preventing water drain or leakage do not prevent steam or gas leakage, steam and gas will continue to leak out of drum (104) and water chambers (500) having water-free zones (100).
With additional measures to be taken it is possible to prevent steam and gas leaking out from of water chambers (500) and entering into water-free zones (100) also means surroundings from wet zones through water chambers (500).
The hot air, steam and also gas exiting from drum perforations/holes (105) or drum entrance opening will go into water chamber (500). In machines where water tank/outer drum (101) is completely closed off, steam is discharged via a ventilation flue at the top of water tank/outer drum (101). It is possible to place a similar steam/gas flue outlet from water chamber (513) on the top section of water chambers (500). Water chamber (500) surrounding drum (104) being open to the atmosphere around the periphery of drum (104) does not impose of all steam outflow occurring from said steam/gas flue outlet from water chamber (513).
In order to prevent steam or gas from leaking out of drum wet-outer surfaces (104-w) where it is formed, a steam/gas flue fan (514) having a suitable flowrate to provide negative air pressure in drum wet-outer surfaces (104-w) must be used. Placing said steam/gas flue fan (514) so that the inlet is at the ventilation flue at the top of water chamber (500) will aid in collecting the hot water at steam that naturally moves upwards.
Air with steam or gas can be directed outside by the steam/gas flue fan (514) via suitable discharge and steam/gas flue chimney systems (515). If there are no discharge means in the system for air with steam, the air steam mixture or is passed through a condenser, and steam is separated from air by condensing.
This method will prevent steam from entering water-free zones (100) within water chamber (500) and from leaking out of water chamber (500).
The gasket at the outside of the chamber (530), which is mounted on the circular outer surface of the water chamber (500), so as to cover the gap between the circular outer surface of the drum and the circular outer surface of the chamber, adheres to both circular elements mounted at the same alignment and provides sealing with negative pressure created by the suction of steam/gas flue fan (514) in the reservoir.

11- The features of the drum and drum holes in narrow band forming a peripheral perforated narrow zone (510) according to the present invention is explained below via Figures 1, 4, 9-15.

Making the area where drum holes are placed narrower and placing said drum holes in a peripheral perforated narrow band zone (510) on cylindrical drum sheet perforated in the peripheral perforated narrow zone (510) in order to make use of the advantages of the invention by making water chamber (500) as small as possible will be an advantageous embodiment for making water chamber (500) narrower and creating water-free zones (100) that are as wide as possible on the surface of drum (104).
Placing drum perforations in peripheral band zone (509) within the boundaries forming peripheral perforated narrow band zone (510) in the rotation direction of and peripherally surrounding the drum and also within the areas where water exit from cylindrical drum sheet perforated in the peripheral perforated narrow zone (510) is possible will make it possible to limit the size of, narrowing the width of and decreasing the volume of water chambers (500). The narrower the limits of the area where peripheral perforated narrow zone (510) where drum holes are located are, the narrower the water chamber (500) can be. If drum perforations in peripheral zone (509) are located close to the rear sheet of cylindrical drum sheet perforated in the peripheral perforated narrow zone (510), this will provide an advantage for application of solutions for speeding up water exit from drum (104) and sizing and mounting solutions for the water chamber.

12- The formation of water channels/Poly-Channels (524) within drum (104) according to the present invention are explained below via Figures 10, 12, 14, 15.

While drum (104) having a conical shape or being positioned to make an angle with the horizontal axis is a functional solution when said drum (104) is empty, it will lose its functionality once drum (104) is filled with materials obstructing the water flow. Despite the angle created for flow, water will have to flow between the materials blocking the flow path on the drum inner surface (104-n). The barrier formed by materials strewn on the surface of cylindrical drum sheet perforated in the peripheral perforated narrow zone (510) will slow down the flow of water, especially during the spin cycle as the compressed materials are jammed against the drum sheet.
Because the barriers formed by the compressed materials on the drum inner surface (104-n) slow down the flow of water through the drum to the perforated zone, the draining and extraction times are longer. The aim is to ensure that, even when drum (104) is filled with materials having high density and low water permeability, water flows towards peripheral perforated narrow band zone (510) where drum perforations in peripheral zone (509) are located and exits drum (104) via drum holes.
It is possible to position the drum holes in a narrow band zone so that water is discharged in a timely manner using the system described in EP2229475 . Said system allows the number of drum holes to be reduced 10 to 20-fold without causing a decrease in the flowrate efficiency of water discharge. While the exit area of water is very limited in the system described in EP2229475 , said system also aims to prevent said holes from being blocked by the materials being treated in drum (104) and ensure a constant but limited outflow of water. Therefore, the discharge flowrate can be suitable to the capacity of the pump used to pump water back into drum (104) and said pump can be used at a high efficiency. Said system regulates water discharge from drum holes. On the other hand, a problem that needs to be solved is ensuring that water flows from non-perforated regions of drum (104) towards where drum perforations in peripheral zone (509) are located at a constant flowrate that is suitable to the discharge flowrate.
A solution to this problem is forming water channels/Poly-Channels (524) on the conical drum sheet perforated in the narrow belt zone (512). Water will flow through water channels/Poly-Channels (524) without coming across any obstacles in drum (104) according to the system described in EP2229475 , as explained above. This system preferably comprises a water channel grate (526) forming water channels along the drum inner surface (104-n) of cylindrical or conical drum (512) which are parallel to or make an angle with the rotation axis of drum (104) using Poly-Ribs/protrusions/sheet bar/grate bars (525) made of metal or plastic protrusions. Said water channels/Poly-Channels (524) are comprised of water channel grates (526) placed on drum outer surface (104-s) or plastic or metal conically molded roller housing (240) parts. Water flows towards the area where drum perforations in peripheral zone (509) though said water channels/Poly-Channels (524). In a conical drum sheet perforated in the narrow belt zone (512), flowrate increases with degree of the conicity of the conical drum sheet perforated in the narrow belt zone (512). Figures 12 show water channel grates (526) and water channels/Poly-Channels (524) formed by them in a conical drum.
In the embodiment as exemplified in Figure 12A, water channels/Poly-Channels (524) are shown which are side by side positioning of the sheet bar pieces suitable for lattice or the like-shaped grating, both as applied in the drum and on the conical sheet of the drum will keep the materials in the drum on water channel grate (526) and away from conical drum sheet perforated in the narrow belt zone (512) so that water channels/Poly-Channels (524) can facilitate flow of water across the length of the cylindrical surface of the drum without coming across any obstacles. As is known, water channel grates (526) also known as trash screens are structures that allow passing of fluids such as gases and liquids between the two volumes they are separating but prevent passing of materials that are desired to keep on one side. In order to achieve this, water channel grates (526) may have the structure of bars or cages of different shapes and sparsity. It is possible to use any structure that fits the general description of a water channel grate (526) and that makes it possible to keep the materials being treated away from the sheet of perforated drum and allows the flow of water on the surface of the drum beneath said materials. In a drum comprising water channels/Poly-Channels (524), water can flow through said water channels/Poly-Channels (524) towards drum perforations in peripheral zone (509) without encountering any obstacles. Water channels/Poly-Channels (524) are created by Poly-Ribs/protrusions/sheet bar/grate bars (525) placed on the surface of the drum (104) to flow the water through drum perforations/holes (105) located in a region of the drum. The shape and dimensions of the Poly-Ribs/protrusions/sheet bar/grate bars (525) have to be suitable to form water channels/Poly-Channels (524) having enough water passageway volume to allow water to flow towards drum perforations/holes (105) on the surface of the drum. It would be right to call the volume where the materials are at the top of the Poly-Ribs/protrusions/sheet bar/grate bars (525) forming the water channels/Poly-Channels (524) as washing material drum also means real drum. The volume below water channel grates (526) extending to conical drum sheet perforated in the narrow belt zone (512) can be referred to as water flow area. Basically there is a kind of effluent system consisting of Poly-Canals under the grids. For example, water flowing from the water grids placed on the roadside to the sewer system under the road and flowing under the streets can be given.
The problem will be practically solved when water channels/Poly-Channels (524) are formed in adequate depth and width so that the material treated within the drum will not reach and/or approach the cylindrical surface of the drum to prevent water flow to reach the cylindrical surface of the drum sheet and flow through the drum perforations in peripheral zone (509) and drain out without any obstacles
Poly water channels/Poly-Channels (524) may have any structure forming indents preventing entry of materials and allowing flow of water on conical drum sheet perforated in the narrow belt zone (512) from the area without holes towards the area where drum perforations in peripheral zone (509) are located. This can be achieved by placing Poly-Ribs/protrusions/sheet bar/grate bars (525) on the surface of drum (104) or directly shaping cylindrical perforated drum sheet (106) to form water channels/Poly-Channels (524) or placing parts or covers in accordance with water channels system to conform to the Poly-Canal definition on the surface of drum (104).
As the system described in EP2229475 aims to prevent drum perforations/holes (105) from getting completely blocked by the washing material, the relationship between the Poly-Ribs/protrusions/sheet bar/grate bars (525), drum inner surface (104-n) and drum holes described in existing system forming water channels/Poly-Channels (524) may be different than said protrusions. The textiles being laundered form a tent-like structure across Poly-Ribs/protrusions/sheet bar/grate bars (525) placed on the drum sheet to prevent to reach drum inner surface (104-n) and to block drum perforations/holes (105) completely. The goal is that said water flow ways and drum holes are below this tent on the protrusions (531). In this case, the height of Poly-Ribs/protrusions/sheet bar/grate bars (525) and the space between the protrusions must be designed with the elasticity of the textile so that the textile forming the tent on the protrusions (531) does not block the drum holes when it stretches towards the bottom of Poly-Ribs/protrusions/sheet bar/grate bars (525). If the protrusions are close enough and high enough so that even if the textile stretches it cannot reach the drum inner surface (104-n), then the placement of drum perforations/holes (105) between the protrusions is not important. However, if the textile can stretch far enough between Poly-Ribs/protrusions/sheet bar/grate bars (525) to reach the drum sheet, then preferably drum holes have to be positioned close to the protrusions to accelerate the water discharge. In fact, if drum perforations/holes (105) are positioned beneath Poly-Ribs/protrusions/sheet bar/grate bars (525), they cannot be blocked by the textiles. The 2 mm height Poly-Ribs/protrusions/sheet bar/grate bars (525) will allow for the desired result, provided that both drum perforations/holes (105) remain unblocked to ensure water flow through the peripheral non-perforated zones (510-n) of the drum to peripheral perforated narrow zone (510) if said protrusions have the proper shape and density.
In conclusion, while it is not important whether or not the materials reach the surface of the drum in the Poly-Rib system (60), it is undesirable in the Poly-Canal system because if the materials stretch enough to reach the drum inner surface (1 04-n), they will restrain water flow in water channels reducing drain flow rate and increasing process time. For this reason, it is preferable that the protrusions of the Poly-Canal system are higher and more densely placed than those of the Poly-Rib system (60) to maintain efficient water drainage.
There is no difference between a cylindrical drum with drum holes in located in a peripheral perforated narrow zone (510) and no Poly-Ribs/protrusions/sheet bar/grate bars (525) and a conical tank with Poly-Ribs/protrusions/sheet bar/grate bars (525) and water channels/Poly-Channels (524) in terms of the application of the present invention except for the water discharge and extraction periods being longer than desired. Any type of protruding structures designed to prevent holes from being blocked and ease water flow within the drum will benefit the efficiency of water discharge and the extraction cycle.

13- Conical drum sheet perforated in the narrow belt zone (512) according to the present invention are explained below via Figures 4, 12, 13.

Positioning drum (104) having drum perforations in peripheral zone (509) in a peripheral perforated narrow band zone (510) at the rear of drum (104) with its front side up and its rear side down and having water channel grates (526) forming water channels/Poly-Channels (524) on cylindrical drum sheet will enable water to exit quickly during discharge. However, positioning drum in this manner is only partially helpful for ensuring water exits said drum quickly during high speed spin cycles.
In these cases, having a conical drum sheet perforated in the narrow belt zone (512) whose diameter gets larger towards the perforated area will make water exit the drum quicker during high speed spin cycles. It is clear that to provide a conical drum structure the cylindrical drum sheet must be conical (512). It will be beneficial to examine the positioning of drum perforations in peripheral zone (509) at the rear side of drum (104), drum (104) having an incline to facilitate water flow towards the holes, drum having a conical structure (512) and application of water channel grates (526) forming water channels/Poly-Channels (524) in drum (104) in terms of household washing machines (57). One feature of household washing machines (57) is that they are generally produced using mass production techniques. While they are defined as household-type, these washing machines produced in large scale production facilities using automated systems can also be used for applications other than household-type. These machines have a drum capacity between 30-40 and 250-300 L. In machines having high capacity, household drum water channel grates (622) used may be fixed and detachable and made of plastic and metal. Due to production techniques, it will be preferable for household drum water channel grates (622) forming the household drum water channel/Poly-Canals (621) within the drum to be made of plastic in household washing machines (57). Figures 14, 15 show household drum water channel grates (622) in the form of household drum water channel/Poly-Canals (621) made of household drum water channel grate bars/Poly-Ribs (623) inside the drum; however, that particular embodiment of the household washing machine does not comprise household drum lifter ribs (607). Household drum water channel grates (622) inside the drum will also fulfill the function of carrying the materials during the rotation of the drum. It is possible to use drum lifter ribs (107) in-between the water channel grates (526). One of the most pressing goals of producers of washing machines is to increase the size of household drum (604) to be placed in a household outer frame (616) having standardized dimensions. In some countries, the volumes allowable for washing machines are very limited. Especially as houses become smaller, the volumes allocated for washing machines also decrease. In Europe, the width and depth of a household outer frame (616) of a household washing machine (57) must not exceed 600 mm in order to fit in the allocated spaces in the kitchens and bathrooms. Setting aside 20 mm for the frame and spaces, the outer drum to be placed inside household outer frame (616) must have a diameter below 560 mm. Even if the washing machine contains a system wherein water tank/outer drum (101) does not oscillate, the diameter of household drum (604) will be around 520 mm. If the machine has a free oscillation body, the diameter of water tank/outer drum (101) will be around 520 mm and the diameter of household drum (604) will be around 480-485 mm. Using the balance system (300) proposed by the present invention and other features of the invention makes it possible to increase the diameter of household drum (604). The diameter of a household drum (604) having the highest volumetric capacity possible may be around 560 mm, taking into account the required distance between household outer frame (616) and household drum (604) and other tolerances. This measurement means that no place is set aside for a water chamber (500) to be placed around household drum (604). When inclined household drum (604) is placed so that the rear section is downwards of the horizontal axis and household water chamber (611) is placed behind household drum (604) in the corner where household drum rear circular base sheet (610) and cylindrical household drum sheet (606) meet, it will be possible to collect the water exiting from household drum holes/perforations (605) at the back of household drum (604) by a water chamber placed behind the drum. With this design, it will become possible use a cylinder having the highest diameter possible to fit in rectangular box as a drum.

14- Discharging water from drum (104) via drum discharge chamber (517) and drum discharge chamber water discharge valve (519) to create completely closed drum according to the present invention is explained below via Figures 10, 12, 13.

When water is discharged from drum (104) through drum perforations in peripheral zone (509) on a peripheral perforated narrow band zone (510) an important embodiment is made possible. The aim of trying to collect a large portion of the water draining drum (104) back inside the drum by pumping said water back into the drum using a circulation pump (112) having a greater flowrate capacity than the drain flowrate of water from the drum is to save water and chemicals in the water by using them only in the drum. In fact, drum (104) could simultaneously be used as a water tank/outer drum (101) and the outlet of the water therein could be opened and closed as desired, and the problem will be solved at the source. In other words, when drum (104) is simultaneously used as a water tank/outer drum (101), there will be no need for water to be present outside the drum. The present invention makes this possible. As exemplified in Figures 10, 12, 13, when a drum discharge chamber (517) completely surrounding the where drum perforations in peripheral zone (509) on a peripheral perforated narrow band zone (510) on drum outer surface (1 04-s) on drum (104) and covering and sealing said holes, the water exiting from said drum perforations in peripheral zone (509) will enter and collect in said drum discharge chamber (517). Said drum discharge chamber (517) will cover the areas where the holes are located by creating a small volume on the conical drum sheet perforated in the narrow belt zone (512). Water exiting drum perforations in peripheral zone (509) will flow to drum discharge chamber (517). When the outlet from drum discharge chamber (517) is closed, drum water will be collected in the drum. However, as the volume of the discharge chamber is markedly smaller than water chamber (500) and the circulation system, the amount of water present in drum discharge chamber (517) during washing will not affect the targeted water saving values. In case water outflow from drum opening gap around drum opening between drum and front panel (114) in between drum and front panel is prevented by fully covering drum entrance/inlet opening (108) with a rotatable door (533, 542) or pumping the water exiting from drum opening gap around drum opening between drum and front panel (114) back into the drum using a drum opening water collection chamber circulation pump (528) having a suitable capacity, it will be possible to confine the water inside drum (104) during washing. The solution provided for connecting drum (104) and water chamber (500) by mounting moving parts outside drum (251) on drum (104) is opening a drum discharge chamber water valve opening (518) in the drum to allow water outflow from drum (104). For this, one or more drum discharge chamber water discharge valves (519) need to be placed around drum discharge chamber (517). Figure 13 shows drum discharge chamber water discharge valves (519) of drum discharge chamber (517) for collecting drum water in the drum in closed position. Said drum discharge chamber water discharge valves (519) mounted on drum discharge chamber (517) can be opened and closed using an electric motor or a pneumatic piston of drum discharge chamber discharge valve (520) of drum discharge chamber discharge valve (519). Said pneumatic piston of drum discharge chamber discharge valve (520) of drum discharge chamber discharge valve (519) used for opening and closing the valve may be placed in a suitable position such as the spaces of drum lifter ribs (107). When the water in the drum needs to be discharged, drum discharge chamber water valve door (521) covering drum discharge chamber water valve opening (518) providing water outlet from drum discharge chamber (517) is closed by pneumatic piston of drum discharge chamber discharge valve (520) as shown in Figure 12A, 13. Drum water passing drum perforations in peripheral zone (509) on drum (104) through to drum discharge chamber (517) flows to water chamber (500) via drum discharge chamber water valve opening (518) that has been opened. For example, Figure 13A shows four drum discharge chamber water discharge valves (519) mounted on drum discharge chamber (517). Water will pass through drum discharge chamber water discharge valves (519) to water chamber (500) due to the centrifugal force created during the spin cycle. Even though there is no need to take special precautions for drum (104) discharging water by rotating, when drum (104) rotation needs to be stopped while water discharge is going on it will be necessary to stop the drum at a position where one of the open drum discharge chamber water discharge valves (519) is at the bottom.
In this way, as the drum becomes a fully closed system during washing operations, the highest water savings can be reached.

15- The angle of the water channel grates (526) on drum inner surface (104-n) with the drum rotation axis according to the present invention is explained below via Figures 15.

As the oscillations and vibrations generated by household drum (604) are dampened via water tank/outer drum (101) using additional weights, springs and suspension connections, drum stretched with respect to water tank/outer drum (101) and in order for household drum (604) to not contact the outer drum during stretching, there needs to be a gap between the drum and water tank/outer drum (101) taking into account the stretching tolerances between the two. Due to the oscillations and vibrations generated in the outer drum by household drum (604), a space large enough to prevent outer drum from hitting household outer frame (616) needs to exist between said outer drum and said household outer frame (616). The drum capacities of household washing machines (57), for which the dimensions of household outer frame (616) are standardized, can have a maximum value of 60-65 L. Whereas in a machine where oscillation tolerances are minimized, it is possible for the drum to have a capacity of 90-100 L even if household drum (604) is placed inside a water tank/outer drum (101) and it is possible for the drum to have a capacity of 110-120 L for a washing machine having a water chamber (500) instead of a water tank/outer drum (101). This indicates that for household machines having a frame width of 600 mm where the invention is utilized has double the capacity of conventional household machines. The first step to achieve this is to prevent the oscillation of household drum (604) during the spin extraction cycle.
While it is possible to produce conical drum sheet perforated in the narrow belt zone (512) for household washing machines (57) using available production techniques, having a conical household drum (604) will require some compromise from the volume of the drum. Theoretically, the outside dimensions of household drum (604) must be limited by the limits of household outer frame (616) in order to place a drum having the largest volume without changing the dimensions of said household outer frame (616). Household drum (604) having a diameter at the limits of household outer frame (616) means that there is no space available for a household water chamber (611) outside the drum. In this case, the only solution is for the outer dimensions of household water chamber (611) to not be larger than the diameter of household drum (604). Draining the water from household drum (604) into a household water chamber (611) having the same diameter as said drum can only be realized using specific solutions. For example, in Figures 14-17, household drum holes/perforations (605) of cylindrical household washing machines cylindrical household drum sheet (606) are placed at the corner of household drum rear circular base sheet (610). Drum sheet forms a water discharge recess in household drum sheet around perforated area (601) through inside of the cylindrical household drum sheet (606) around household drum holes/perforations (605) area; in this way a water discharge chamber (619) outside cylindrical household drum sheet (606) inside household drum (604) is formed. Water exits the drum in the same level with household drum rear circular base sheet (610) and in a way as to not go beyond the diameter of cylindrical household drum sheet (606). For the water exiting from the holes to continue flowing past household drum rear circular base sheet (610), water discharge chamber outside household washing machines drum sheet but inside water discharge chamber (619) is surrounded by a household water discharge chamber peripheral cover sheet (620) having the same diameter as the cylindrical drum sheet to cover the rear corner of the drum as shown Figures 16, 17. Said household washing machines household water discharge chamber peripheral cover sheet (620) is circular and has the same diameter as cylindrical household drum sheet (606) and is mounted there onto in a leak-proof manner. While the water in the area defined as water discharge chamber (619) outside cylindrical household drum sheet (606) but inside the household drum (604) that is surrounded by household water discharge chamber peripheral cover sheet (620) has exited the drum sheet, it has not completely left the volume of household drum (604). Figures 55A, 56-58 show the water discharge chamber (619) obtained by shaping of the cylindrical household drum sheet (606). Said water discharge chamber volume may be formed by different techniques and auxiliary plastic parts placed inside the drum. This way, the water discharged from household drum (604) will flow through household drum water channel/Poly-Canals (621) formed by household drum water channel grates (622) in the household washing machines drum and reach household drum holes/perforations (605) on the cylindrical household drum sheet (606), wherefrom it will flow into the water discharge chamber (619). The water entering water discharge chamber (619) will flow on circular household water discharge chamber peripheral cover sheet (620) and into household water chamber (611). Since the household drum (604) is inclined towards backwards, the water outlet from the household drum entrance opening gap (627) will be less than the horizontal drum condition. When a household drum (604) comprising household drum water channel grates (622) forming household drum water channel/Poly-Canals (621) inside said household drum (604) is placed at an incline so that water will flow towards the rear, exit of water from household drum (604). However as high speed rotation of the drum will decrease the effect of the incline on the flow of water, a different solution is needed to increase the flow of water during the extraction cycle. Placing the household drum water channel grate bars/Poly-Ribs (623) forming household drum water channel/Poly-Canals (621) on the cylindrical household drum sheet (606) at an angle with the axis of rotation will speed up the flow and exit of water during the extraction. During extraction household drum (604) rotates at the same direction. The sweeping effect created by protrusions placed at an angle inside the helical structure created by household drum water channel grate bars/Poly-Ribs (623) placed at an angle determined according to the direction of rotation of household drum (604) during the spin extraction cycle will direct the water towards the rear of the drum and out of said household drum (604). The water will flow out from the rear corner of the drum and into household washing machines water chamber (611) wherefrom the water will flow into household water collection/storage tank (625) via household washing machines water chamber-storage tank connection (624). As household drums (604) of household washing machines are inclined towards the rear, there will be considerably less water flow from the drum opening compared to horizontal drums. Despite this, water flowing from the drum opening will flow into an elastic household water collection/storage tank (625) via household drum opening water collection chamber-water collection/storage tank connection (626). A household washing machines circulation pump attached to the outlet of household water collection/storage tank (625) pumps the water coming to the tank during the washing cycle directs the water towards discharge when needed. While in Figures, the measurements of the exemplary household washing machine are close to the measurements of the application of the invention, the positioning and measurements of household circulation pump (612) and household circulation pipeline (613) are shown schematically to provide clarity. The measurements and proportions of the parts in the drawings are given only as examples.
While in industrial washing machines, the circulation system is connected to the drum via the drum cover, in household washing machines (57) it is acceptable for it to be connected to the drum opening water chamber and be placed within the bounds of the outer frame.

said water discharge chamber (517) comprises at least one water discharge valve (519) which enables the water entering said drum discharge chamber (517) via the drum perforations (509) to be discharged to the water collection chamber (501) in a controlled manner,

water discharge from the drum (104) via the drum perforations (509) is completely prevented as said water discharge valve (519) is closed such that the drum discharge chamber (517) blocks the water passage, and

said washing machine (50) comprises a water collection chamber (501) which is placed so as to enclose the drum discharge chamber (517).
A washing machine (50) as described in in any preceding Claim, characterized in that;
said water chamber (500) is formed so as to enclose the wet areas/surfaces (100-w) of the drum (104) and to leave the drum water-free zone (100) of the drum (104) out,

said water chamber (500) comprises a flow path on water chamber (508) which enables the water drained from the drum (104) to flow toward the drain outlet (503),

said water chamber (500) comprises water chamber barriers (511) together with water barriers (122) on the drum surface which prevent the water from leaving the water chamber (500) or the flow path on water chamber (508) or from overflowing from the water chamber (500) while collecting the draining water from the drum (104) and enabling the water to flow toward the drain outlet (503) via the flow path on water chamber (508), and

said flow path on water chamber (508) on water chamber (500) has a water flowrate higher than the discharge flowrate of draining water from the drum (104) so that accumulation of water in water chamber (500) is prevented and removal of water from drum (104) without coming into contact with drum (104) again is ensured.
A washing machine (50) as described in any preceding Claim, characterized in that;
in order to provide said water-free zones (100) on the drum outer surface (104-s) the water chamber (500) is in connection with a circulation pump (112) which has a pumping capacity higher than the drain flow rate of the drum, and which pumps the drum (104) drain water reaching the water drain outlet (503) to the drum (104),

wherein said circulation pump (112) has a higher pumping capacity than the drum discharge flowrate, and wherein the drum discharge flowrate is lower than the pumping capacity of circulation pump (112) so that water flowing from drum (104) to water chamber (500) via the water flow path on water chamber (508) does not overflow from water chamber (500), reach drum outer surface (104-s) or overflow or pass to water-free zone (100).
