Definitions

  • 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.
  • 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.
  • any and all sizes required by the system of the invention may be applicable without limit.
  • 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).
  • 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.
  • 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.
  • Motor(s) to move parts on the free-drum (130) that are the drive source may be mounted onto fixed chassis (111) of the machine outside water chamber (500) or may be mounted directly onto free-drum (104) such that it can rotate with said drum.
  • Movement transfer parts such as pulley rotated by movement transfer parts such as belts (402) connected to electrical drive motor on fixed chassis (133) that is mounted outside the water chamber (500), preferably on top of the water chamber (500), transfer the movement to the movement transfer parts (401) connected to moving parts (200) inside water chamber (500).
  • Figure 16 demonstrates (B) a rear perspective view of a drum in a rear side base opened water collection chamber wherein said drum comprises rollers attached to gear pulleys driven by a gear belt rotated by a (A) single motor and (C) two motors on a fixed chassis according to the present invention.
  • Figure 17 demonstrates side sectional view of an indented drum comprising rollers having cylindrical grindstone pieces and that are attached to gear pulleys driven by a gear belt rotated by a motor on a fixed chassis and coarse grindstones in-between said rollers according to the present invention.
  • Figure 38 demonstrates (A) a sectional perspective view of a roller having cylindrical grindstone pieces at rear side and spherical grindstone pieces at front side that is rotated by a motor belt pulley system and (B) a detailed sectional perspective view of frontal bearing and bearing lock mechanism of a roller having spherical grindstone pieces and (C) a detailed sectional perspective view of rear ball bearing of a roller having cylindrical grindstone pieces according to the present invention.
  • Figure 62 demonstrates a schematic view of (A) opposing forces FI and F2 created by balance weights balancing each other and (B) and the opposing force created by FI and F2 created by balance weights balancing the Fx force creating an imbalance in the drum in a two weight balance system according to the present invention.
  • the figures illustrate a stone washing and spinning machine that is one of the important areas of application of the invention.
  • rollers (201) Abrasive rollers (202) with grindstones are placed between lifter ribs (107) for stone washing.
  • the rollers (201) can be rotated between bearings placed on drum front circular base/opening side (109) and drum rear circular base/shaft side (110) of the drum sheet, at desired speeds via motors placed on drum rear circular base/shaft side (110) as in the front.
  • a balance system (300) is mounted both on the rear along with the roller motors connected to moving parts (134) and on the front of the drum.
  • 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.
  • 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).
  • 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.
  • 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.
  • areas outside drum (104) that are defined as water-free zones (100) may be areas on drum outer surface (104-s) where contact with water is prevented using the technical or structural precautions presented by this invention, as well as isolated areas in movement system (142) for placing the devices outside the drum that are isolated against water entry or isolated units in movement system (143) of the devices mounted on the outside of the drum.
  • Water flow 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.
  • the depth and width of Poly- Canals and the shape of Poly-Ribs/protrusions/sheet bar/grate bars (525) forming said Poly-Canals (524) should be chosen according to the type of treatment and the type of material to be treated. Especially for industrial machines, the materials to be treated can range from very thick, large and hard materials such as dust mats with rubber bottoms to small and delicate materials such as elastic socks. For this reason, it is important to take the physical properties of the materials to be treated into account when designing Poly-Canals and Poly-Grates.
  • Water channel grates (526) can be made from plastic or metal and may be an integral part of drum (104), or be reversibly mountable onto drum (104).
  • drum discharge chamber water discharge valve (519) to create completely closed drum according to the present invention is explained below yia_ Figures 25, 29, 32-34, 69, 81, 82, 85.
  • Hinged drum door (533) is locked by electric or pneumatic hinged drum door lock (536) systems mounted on drum (104). When said locks secure the door on the opening flange, the door is fixed onto the drum by hinged drum door gasket (538) in a leak-proof manner.
  • any technical means necessary for the door including locking of the drum door, controlling of the locks and the position of the door and automatic opening of the door. What is important to consider is that for the door to be opened, drum (104) needs to be at the same position every time.
  • a second point to consider is that as hinged drum door (533) rotates along with drum (104), there is a need for a second fixed chassis drum safety door (540) for providing security on the outer frame of the machine as exemplified in Figure 81-83.
  • recessed protruding threaded rollers (209) comprising indented surfaces that can engage with each other can be used to solve this problem.
  • rollers are cylindrical and buckled and mounted apart from each other, it is unavoidable that the rollers gets tangled with the material and gets stuck. To prevent this, the sided of the rollers must be covered to block the textiles from going under the rollers.
  • part of the rotating parts must be covered in a way to not permit entry for any material being treated in drum (104), especially textiles. This is possible by a variety of methods.
  • molded roller housings (234) having a cylindrical housing suitable for the diameter of the roller and preferably made of plastic, aluminum or a similar material may be placed under the rollers as shown in Figures. Molded roller housings (234) are molded to fit against cylindrical perforated drum sheet (106) at the bottom and against the surface of the roller at the top and placed under the rollers, spaced apart just enough that no materials can enter there between.
  • molded roller housings (234) comprise molded roller housing water discharge holes (235) required for water discharge from drum (104). Molded roller housing water discharge holes (235) are positioned within molded roller housings (234), in order for rollers (201) to prevent the materials from reaching the holes.
  • the system proposed by the invention provides water-free zones (100) where balance system (300) can be mounted, which have made it much simpler to use said system. Thanks to mounting motor to move parts on the drum (130) driven moving parts outside drum (251) together with electricity connection, electric and electronic control systems (900) which can be placed in rear and frontal sections of the drum, made it possible to apply dynamic balancing techniques on the washer extractor machine.
  • balance weights (301) normally placed on drum front circular base/opening side (109) and drum rear circular base/shaft side (110) or on the front and rear of cylindrical perforated drum sheet (106) to balance each other out will be moved by balance weight movement motor (306) in order to balance the imbalance in drum (104). Therefore, at last one balance weight (301) each must be present on either side of drum (104).
  • Figure 70 shows an exploded view of balancing systems mounted around drum cylinder and Figure 8 shows an exploded view of balancing systems mounted on drum circular base surfaces.
  • Figures 64-68 provide detailed images of the balance system from different angles.
  • circular base/shaft side 110" according to the present invention is explained below via Figures 1, 2, 5-9, 18, 32, 34, 51-78. If drum front circular base/opening side (109) and drum rear circular base/shaft side (110) where the balance system is located is outside of water tank/outer drum (101), the addition and removal of balance weights (301) can be done easily and quickly depending on the loading and operating conditions of the machine. The amount of the unbalanced load generated in drum (104) during the extraction cycle may vary a lot depending on the type and amount of material being treated therein. If the drum (104) is fully loaded, the chances of the material being distributed homogeneously in the drum (104) are higher than the drum loaded with fewer amounts.
  • Balance liquid (337) is distributes equally between balance liquid containers (331) at the beginning of the extraction cycle, other than when balance is taken, therefore, they do not cause imbalance in drum (104) because they have equal weights.
  • the direction of the unbalanced load vectors in drum (104) is determined by balance control system (344) in drum front circular base/opening side (109) and drum rear circular base/shaft side (110).
  • Balance control system (344) rotates balance liquid container moving chassis (332) so that balance liquid container axis (339) corresponding to the center of gravity of balance liquid containers (331) overlaps with the imbalance load vectors in drum (104). Said rotation is realized by a balance liquid container movement motor (335).
  • This system utilizes an equilibrium weight (341) positioned opposite rotatable balance liquid container (340) to balance it.
  • the necessary amount of balance liquid (337) can be transferred from an equilibrium liquid container (342) to rotatable balance liquid container (340).
  • the liquid transferred to rotatable balance liquid container (340) is returned to equilibrium liquid container (342) at the end of the spin cycle.
  • balance liquid (337) may be supplied by balance liquid fittings (343) connected to drum (104). Water fed to drum (104) and used as balance liquid (337) in rotatable balance liquid container (340) can be removed via the discharge line during and/or at the end of the extraction cycle.
  • the balance systems must comprise at least two weights. Said two weights are mounted opposite each other close to the rotation axis of the drum on the frontal and/or rear section of the drum on a bearing system capable of rotating 360° as in the first example. Different to the two-weight balance system described above, in this embodiment while one weight is fixed in position near the center, the other weight can move towards cylindrical perforated drum sheet (106) as in the three-weight balance system. 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.
  • Gas burner (921) system is also applicable for all drum types that has peripheral perforated narrow zone (510).
  • FIG. 115 shows an embodiment comprising a lighting system comprising lighting units inside drum (918) dispersed on drum inner surface (104-n) surface, wherein said lighting system can be programmed so that only the lighting units having the desired angle based on the position of drum is turned on during rotation of drum, thereby providing optimum lighting for visual monitoring of the drum interior.
