Definitions

  • This invention is related to the drums that are used in the washing machines and tumble dryers.
  • drums inside such white goods as washing machines and tumble dryers used so as to clean the laundry and dry them.
  • the drums are units with a perforated structure which can spin at a pre - determined speed.
  • These perforations are designed with a view to enabling the water to reach the laundry in the drum of the washing machine and discharging water in the drum during the process of wringing out.
  • these perforated structure functions to move the evaporating water off the laundry.
  • drum units which functions without wearing out the laundry are required.
  • the perforated drum of present invention has been developed for the washing machines and / or tumbles dryers and contains perforations having special geometrical forms to prevent the laundry from wearing out. Accordingly, each drum perforation has been produced extending toward the outer surface of the drum; their internal and external flanges moved off the center of the perforation; and the internal surface of the perforations are designed in such a way as not to form a sharp line and its cross-section to have a curved surface. Thus, the wearing out of the laundry during the washing and drying processes is avoided. Moreover, even the existence of burrs left around the perforations during the production is considered as a factor that does not affect the laundry. Additionally, this eliminates the need to perform the burr removing process during the production of the drum and reduces the production costs of the drum.
  • the aim of this invention is to ensure that the perforations in the drums used in the washing machines and/or tumble dryers do not harm the laundry.
  • Another aim of the invention is to produce drum perforations in such a form as to prevent the laundry from wearing out.
  • a further aim of this invention is to provide a safe drum the manufacture of which is easy and cost-effective.
  • the perspective view of a sample white goods (1) is given in the Figure 1 .
  • the white goods (1) is given as a washing machine but the invention can be applied to both the drying machines and also the machines that can wash and dry the laundry.
  • the laundry and drying machines include a tub (2) containing a rotatable drum (3) with perforations.
  • Drums (3) are generally manufactured by circularly forming the flat sheet materials after perforation.
  • a laundry loading opening is placed at the frontal side of the drums (3).
  • Perforation may be applied to the back wall of the drum (3) which is in flat form.
  • a drum (3) with perforations (4, 4') is shown. While, the perforations (4, 4') here are shown on the curved surface of the drum (3), they can also be placed on the back wall (D) of the drum (3).
  • FIG. 3 a cross sectional geometry of a drum perforation (4') of the prior art is shown.
  • the edge (7') of this drum perforation (4') at the internal surface of the drum (5') (the surface contacting with the laundry) and the edge (8') at the external surface (6') are sharp. Since the internal and external edges (7', 8') of drum perforation (4') in such a geometrical structure contact with the laundry thus damaging the clothes, new drum perforation (4) with different geometrical structures have been developed as shown on the Figure 4-6 .
  • the common points of drum perforations (4) of this invention are that the perforation (4) is extended towards the external surface of the drum (6), that the internal and external edges (7, 8) are alienated away from the perforation center (C) and that the internal edge (9) of the perforation is formed by avoiding any sharp lines, in a way that the cross section of the internal edge has a curved surface (10). Additionally, the section, where the internal surface of the perforation (9) and the internal surface of the drum (5) are connected, is rounded.
  • the sample drum perforation shown in the Figure 5 is similar to the perforation at the Figure 4 ; the difference here is that there is a surface (12) in the drum perforation (4), the cross section of which is flat and which divides the curved surface (10) into two.
