Definitions

  • the present invention relates to a washing or drying machine comprising a tub, a rotating drum provided in the drum and at least a lifter arranged on an inner peripheral surface of the drum.
  • the shape and dimension of the lifter is a sort of compromise between the need of assuring an efficient washing process and the need of avoiding damages to clothes.
  • An object of the present invention is to provide a washing machine of the type mentioned at the beginning of the description which does not present the above problems.
  • the lifter is divided into a fixed part attached to the drum wrapper and a movable part which can rotate or slide in radial direction. Between the movable part and the fixed part one or several springs are interposed which urge the movable part in extended position. Therefore the overall height of the lifter is changing depending on the position of the movable part (extended position-retracted position).
  • the spring force and mass of the movable part is predetermined so that the movable part is moving in and out during different steps of the wash process to increase gentleness, wash performance and water extraction performance.
  • the solution of the present invention improves the mechanical action on laundry and allows an adaptation of the lifter shape to the actual load size.
  • the solution according to the invention improves gentleness, reduces unbalance and supports laundry distribution between spinning steps.
  • the lifter according to the invention reduces tangling/wrinkling and makes easier unloading of all loads removed from drum wrapper.
  • a rotating drum 10 of a front loading washer is rotatably mounted in a tub (not shown) and it is provided with at least a lifter 12.
  • the lifter 12 comprises a hollow base portion 12a fastened to the drum 10 and a movable portion 12b hinged along an axis X to the base portion 12a.
  • the movable portion has a convex smooth surface 14 facing the rotating axis of the drum 10.
  • a U-shaped spring 16 ( figure 3 ) having a first end 16a acting on the base portion 12a of the lifter 12 and a second end 16b acting on the concave surface of the movable portion 12b.
  • the movable portion 12b can assume a first extended position shown in solid lines figures 1-4 in which the upper surface 14 of the lifter is inclined with reference to the axis of the rotating drum and a second retracted position (shown in dotted line in figure 3 ), in which the upper surface 14 of the movable portion 12b is less inclined (or horizontal) than in the first configuration and it is substantially flush with side edges E of the hollow base portion 12a.
  • this latter is provided with a detent 18 cooperating with a corresponding L-shaped edge 20 of the base portion 12a.
  • This embodiment in which the movable portion 12b is hinged to the base portion 12a is only one of the several ways in which there can be a relative movement between these two components.
  • the movable portion 12b can slide inside the base portion 12a thanks to telescopic coupling.
  • compression springs are used instead of a U-shaped spring.
  • the base portion 12a instead of being fastened to the drum 10, can be obtained integral with the drum, for instance by providing hollow seats in the drum metal wrapper.
  • each movable portion 12b can be chosen so that it can assume a retracted position in the tumbling phase, depending either on the rotating speed of the drum 10 or on the actual laundry load in the drum.
  • the lifter according to the invention may be used in the drum of a dryer as well.
