Definitions

  • This invention relates to surface structures of rotating drums used in washing machines.
  • rotating drums which are used in washing machines and laundries to be washed are put therein, have a crucial role in the washing and spinning performance of the machine.
  • To enhance the washing and spinning performance of the machine to increase the contact area of the drum with the laundry, and to discharge more water during spinning, it is necessary to increase the total orifice area on the drum.
  • a number of engaged rings and a number of adjacent ring groups comprising the rings are provided on the drum surface.
  • the rings are in a form of nested successive elevations and recessions, and water discharge orifices are provided on the elevations and recessions.
  • the contact area of the drum surface with the laundries is increased. This is a factor for increasing the washing performance.
  • An advantage of the engaged rings, which are engaged as elevations and recessions, is that they ensure increasing the endurance of the drum surface. Therefore, a high number of water discharge orifices can be opened in desired portions of the rings. It is known that the increase of the water discharge orifices is also a factor for enhancing the spinning performance.
  • An aim of the invention is to improve washing performance by increasing contact area between the drum and laundry and to improve spinning performance by increasing total orifice area on the drum, by means of structures formed on drum surface.
  • Another aim of the invention is to form an easily producible, cost effective, less energy consuming washing machine drum with increased washing and spinning performance.
  • Embodiments of the washing machine drum surface are shown in annexed figures, wherein;
  • Figure 1 shows perspective view of an exemplary washing machine drum (1).
  • Figure 2-4 show structural details of the drum surface (2) therein and by this structure, increasing the contact area of the drum surface (2) with laundries and increasing the number of water discharge orifices (4) are aimed.
  • Figure 2-3 show details on the drum surface (2).
  • a number of engaged rings (3) and a number of adjacent ring groups (5) comprising the rings (3) are formed on the surface (2).
  • Rings (3) are made in a form of nested successive elevations (3a) and recessions (3b). Thanks to a number of elevations (3a) and recessions (3b), the area where the laundries contact with the drum surface (2) is increased. This is a factor for enhancing the washing performance.
  • the rings (3) which are shown in Figure 2-3 , are exemplary formed in round structure.
  • the rings (3) may be in elliptical or multilateral (the edges may be linear and/or curvilinear) structure.
  • the joints of the edges are rounded (for the protection of laundries).
  • the spinning performance is low since water extracted from the laundry does not completely leave the internal surface of the drum in flat surface drums.
  • This invention enables water, which is in the drum surface, to flow to the recessions (3b), to discharge from the orifices (4) and spinning performance is enhanced.
