Definitions

  • 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.
  • 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
  • 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.
  • 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.
  • 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.
  • pumice stone Some of the problems caused by the utilization of pumice stone are as follows: transportation from volcanic mines where they are produced to areas where they are used, storage, environmental issues such as transportation and dusting in the production areas, emptying the machine after stoning treatment to clear textile of pumice stone, clearing textile of pumice stone, reloading and rewashing of textile to clear away pumice dust and transport of pumice waste to safe waste areas where it won't cause environmental pollution.
  • different materials were tested and different methods were evaluated for abrasive applications. All particular mechanical abrasive materials cause environmental pollution.
  • Bleaching, corroding, abrasive and dye remover chemicals are used along with mechanical abrasive materials or by themselves during washing.
  • a natural material, "enzyme,” is also commonly used by itself or along with pumice stones during stone washing. As it is a natural material, it is accepted to be the least harmful chemical used in denim washing. Even though different materials, methods, techniques and chemicals have been used, very few changes have occurred in the past 30-40 years in terms of industrial type stone washing machines having perforated cylindrical drums.
  • mechanical abrasive materials wear down areas they come in contact with such as the drum and the ribs and the chemicals used cause chemical corrosion.
  • drum inner surface (104-n) is covered by stainless steel; however, no method has been able to provide a satisfactory solution to this problem.
  • Simsek describes a machine providing stone washing ability by imparting abrasive characteristics to the surface of the drum instead of loading abrasive particles therein, in 2017 by an application titled "Abrasive Stone Washing Machine” (W02017151074A1, 2017-09-08). Simsek also describes abrasive grindstones attached onto drum inner surface (104-n) in the manner to form protrusions thereon in a European patent (EP2229475, 2017-07-12). While the desired results of these applications were achieved, it was not possible for them to be utilized in practical applications.
  • the reason for that is that the length of process time required to reach the desired results using these systems is 10 times longer than those using pumice stone. This means that in order to obtain the capacity of one conventional stone washing machine, ten machines with abrasive drums need to be used.
  • One of the reasons for that is that while grindstone can be produced to have higher abrasive characteristics than pumice stone, there is a big difference between the two in terms of the surface area that comes in contact with the textiles. When a sufficient amount of pumice stone is added in with the textile to undergo abrasion treatment, the pumice stone gets crumbled down to dust and spreads over the surface of the textile.
  • rollers having abrasive surfaces for abrading applications is known in the state of the art. Rollers having abrasive surfaces are used in many different types of machines such as potato peelers.
  • the problem to be solved is mounting the mechanical and electrical systems to drive the abrasive parts such as rollers placed inside the drum at the desired speeds on the outside of the drum.
  • the present invention aims to solve this problem.
  • the first step to solving this problem was described in the system disclosed by Simsek in EP2229475.
  • Application of the system disclosed in EP2229475 makes it possible to drain all the water that is exist in between inner and outer drum. So by application of the EP2229475 outside the inner drum and inside the outer drum is empty.
  • the textile will move contacting with abrasive surface across the abrasive moving parts during the rotation of the drum and therefore the desired wearing result will be achieved hundreds of times faster.
  • Parts that are moving in ways other than rotation, such as by vibration, will create a dynamic movement that will increase the physical effect obtained only by the rotation of the drum by tens and hundreds of times and decrease treatment time and as a result increase efficiency and decrease costs by providing savings in time, energy, manpower and resources and provide a more environmentally friendly process.
  • Moving parts placed within the drum will increase the physical effect provided by laundry washing appliances and therefore increase the quality of the treatment while reducing treatment time and chemical consumption.
  • One of these effects is rubbing the laundry against each other.
  • Fraser US2002029594, 2002-02-07
  • This system had some issues due to its mechanical structure and coupled with its costs, it had limited application. Its mechanical structure makes it even more difficult to adapt to industrial size appliances than to household appliances.
  • Moving parts rotating, vibrating or oscillating eccentrically on the drum surface will increase the rubbing effect and the quality of washing.
  • a machine having rotating brushes will be able to clean floor/dust mats and other hard material much faster.
  • rollers having plastic protrusions will create rubbing effect on the laundry by rotating slowly.
  • the Poly-Rib system (60) describes a protruding drum surface with reduced drum perforation to limit water discharge to circulation pump capacity.
  • a large portion of the drum holes are clogged by the laundry during draining and spin extraction. Therefore, although there are multiple holes in the drum, the water discharge is irregular. The holes must be kept open at all times to ensure regular, almost constant flow and continuous water discharge from the drum even though the amount of holes is much less than that of conventional drums.
  • Poly-Rib system (60) ensures that the water outlet from the drum is continuous and limited, while the Eco-Drum system (61) pump that limited water from the outer drum back to the inner drum with a proper flow rate capacity pump.
  • Eco-Drum system (61) describes a pumping system to pump draining water from the tub to the drum that have higher pumping capacity than draining water from inner drum to outer drum.
  • the common purpose of the two systems is to prevent the presence of water in the outer drum. So these two systems together make it possible to collect all the water in the machine in the drum and evacuate all the water out of the outer drum. The evacuation of the outer drum allowed a significant amount of water savings in the washing machines. If there is no water in the outer drum, it is appropriate to ask why still an outer drum is needed.
  • Moving parts can be moved using a motor system (400) placed outside of the drum. Possibility to have motor systems (400) placed on the drum outer surface (104-s) give many different mechanical applications on the washing machines. These moving parts can also eliminate the imbalance caused by the uneven distribution of the laundry within the drum during the spin cycle and the resulting vibration of the machine.
  • front-loaded horizontal washing machines providing a spin cycle have a balance system that can be summed up by two principles.
  • the most commonly used balance system utilizes spherical marbles that are free to move within a circular tube or channel placed at the same rotation axis of the drum, wherein these spherical shape weights can be displaced to provide a counterweight to the imbalance.
  • a system comprising two weights rotating freely around the bearing at the rotation axis may be included in this system. Many application options are suggested for this system and some of these have been applied to the front, the rear or the front and the rear of the drum are together.
  • the system is based on the principle of the marbles being displaced by the eccentric motion of the drum in a manner to provide a counterweight to a possible imbalance in the drum. While this system can ameliorate the imbalance, it cannot eliminate it completely.
  • Another balancing system known and used in the art is the addition of external weights to provide a counterweight. Obtaining a counterweight by adding a weight was first proposed by Kahn in 1945 (US2534267, 1950-12-19) and then developed further in 1946 and 1948 (US2534268 and US2534269).
  • the balance system (300) proposed by the invention operates under the principle of counterweights driven by motors to be displaced in a controlled manner to balance the loads in the front and rear of the drum to restore the balance.
  • the spinning process will be much faster compared to water-based balance systems and much more sensitive compared to ball balance systems, the balance can be maintained at high sensitivity throughout the spin cycle, the volume required to put aside for the balance system (300) will be much smaller and there will be no need for water consumption.
  • Water free outer drum surface provide not only mechanical and motor system (400) application but also give possibilities apply sensors and control systems.
  • Disposing Machines for determining the imbalance on parts of different weights and sizes that rotate at high speeds in order to permanently provide balance for said parts and these methods have been used in many different technical industrial applications, especially with the development of electronic systems. It is possible to commercially obtain both hardware and software products for these machines.
  • the present invention aims to provide washing machines with features of "dynamic balance machines”.
  • washing machines are heated by different methods using electricity and steam.
  • the physical conditions of the substructure requirements cause more serious problems to increase suppling of the energy while using electricity.
  • high capacity industrial machines utilize steam instead of the electricity that widely used in small machines as domestic and commercial using.
  • Steam is utilized by adding it directly to the washing water or for heating the washing water in a heat exchanger indirectly.
  • energy is required in laundries for heating the washing water of the washing machine and for heating the dryers and irons when necessary.
  • applications where dryers and irons utilizing gas in the form of LNG, LPG or NG are used have eliminated the necessity of using steam.
  • steam is mostly necessary for washing machines. Providing a practical and economic solution to heat the washing water in washing machines will also provide a solution to spend less investment to construct the infrastructure system to provide steam. Therefore, using gas to heat washing machines is additionally important in terms of finance.
  • 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.
  • 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.
  • washing machines 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.
  • 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.
  • the description and figures depict a medium-scale industrial machine in order to exemplify the applications.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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 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.
  • 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).

  • Drum perforations/holes (105) can have a maximum size of 5-6 mm.
  • the minimum size of drum perforations/holes (105) is limited by production techniques.
  • 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).
  • 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.
  • 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.
  • 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.

  • Stone-washing is a treatment done in the presence of water. Increasing the weight of the textile by wetting will increase the friction between the textile and the abrasive material and lead to an increase in efficiency. However, there is always some excess amount of water in the drum, although it is not required.

Even simply placing a shaped sheet roller (239) under the roller to serve as roller housing will prevent textiles from going under the roller. Moreover, fixed grindstones (243) mounted next to the abrasive roller will block the material without needing a special buffer. Said molded roller housings (234) or barriers/buffers must be selected according to the physical features of the material, such as thickness and touch. If the textile is jeans, as the fabric is thick denim, a few mm of distance between the buffer and housing will be sufficient. However, for thinner materials, such as socks, it will be necessary for the barriers to cover the area around the roller completely, such as fixed brushes between rollers (208) the ends of which contact the roller.

  • conically molded roller housings (240) In a drum (104) having a conical drum sheet perforated in the narrow belt zone (512), conically molded roller housings (240) must be used as roller housings. Having a conically molded roller housing water channel (241) extending towards the discharge holes parallel to conical drum sheet perforated in the narrow belt zone (512) will provide water flow within the roller housings.

In the balancing step, the system rotates until the moving weight is positioned against the imbalanced load. The moving weight then moves towards cylindrical perforated drum sheet (106) until a counterweight equal to the imbalanced load is generated.

  • the motors used in the system are chosen from among motors capable of operating in water or the whole of the balance system including the motors are isolated against water. When the balance system is isolated in this manner, it can be used with drums (104) rotating in water tank/outer drum (101).
  • the "mechanical and dynamic balancing method" described in detail for washing machines with a drum can be applied to any type of weight rotating at high speed and having changing imbalance conditions. It is to be noted that systems rotating horizontally or at an angle with the horizontal axis also include centrifuge machines rotating at high speeds at a 90° angle with the horizontal axis. While these vertically rotating systems do not have the resonance issues associated with horizontally rotating systems, it is known that said vertical systems used for spin cycles also have significant balance issues. In vertically rotating centrifugal spinning machines, the water exiting drum (104) is discharged from the machine directly via a discharge channel; therefore precautions for protecting the balance system against water can be easily taken.
  • pneumatic or hydraulic hardware are necessary for cases where means such as covers, pistons and valves are used on the drum. Therefore, hoses and connections and related fluid based control, directing, opening/closing systems need to be present on the drum so that said systems can operate. While it is possible to use different systems such as pressurized air, steam, hydraulic oil or water systems; pressurized air systems are most preferable as they are sufficient, economic and easy to use.
  • the pressurized air required by the pneumatic systems may be provided via drum shaft (103). However if the amount of air required is small enough to be generated on the drum, an air source such as a small air compressor/pump (907) would be sufficient.

  • liquid or gaseous chemicals are directly injected into the drum via drum door (118).
  • As water does not enter drum (104) via water tank/outer drum (101) according to the present invention it is generally not possible to convey fluids via drum door (118) and circulation system. If homogeneous and fast distribution of the chemical within drum (104) and homogeneous contact of the chemical with the material is desired, it would be advantageous to inject the chemical from multiple locations.
