Definitions

  • the present invention relates to a washing machine.
  • a washing machine generally includes a rotatable drum for containing laundry to be treated, a tub disposed around the drum, and a motor for driving the drum to rotate.
  • a fluid for cleaning the laundry is mainly contained in the tub, and at least partially enters the drum to soak and clean the laundry in the drum.
  • the objective of the present invention is to avoid washing dirt to accumulate inside a tub.
  • a washing machine provided with a tub for containing a detergent solution and a rotatable drum located inside the tub, wherein an inner surface of the tub is at least partially covered with an anti-sticking coating.
  • an outer surface of the drum is at least partially covered with an anti-sticking coating.
  • the coating may be a nanometer coating, a ceramic coating, a carbon film or an organosilicone coating, where the carbon film may be made of amorphous carbon.
  • washing dirt of the tub is greatly reduced.
  • washing dirt is prevented from accumulating on the surface easily in a washing process since washing dirt adhered temporarily is flushed away by shaking and striking of water flows.
  • the washing machine is further provided with a drum-cleaning program, a lot of high-speed water flow generated in the running of the drum-cleaning program may desirably flush away accumulated washing dirt.
  • outer surface of the drum may be also partially covered with an anti-sticking coating, so that the outer surface of the drum can be desirably kept clean as well.
  • a washing machine 1 shown in FIG. 1 has a case body 2.
  • a tub 4 is disposed inside the case body 2 in a suspended manner through a damping apparatus 3.
  • the tub 4 may contain a fluid for cleaning laundry, in particular a detergent solution.
  • a drum 5 is disposed inside the tub 4 and is rotatable under the driving of a motor 6. A washing operation is preformed on laundry in the drum 5.
  • An inner surface 40 of the tub 4 and an outer surface 50 of the drum 5 are covered with anti-sticking coatings 10 shown in FIG. 2 and FIG. 3 .
  • the material of the anti-sticking coating 10 may be organosilicone, ceramic, amorphous carbon film, and the like, and more desirably a nanometer material. These materials are hydrophobic and have a low skin-friction coefficient, so that they are easy to clean and are corrosion resistant. Therefore, washing dirt does not accumulate easily on the drum and the tub, making laundry after washing cleaner and more hygienic.
