Definitions

  • the invention is based on a washing machine with a container for laundry and a laundry mover arranged therein, which can be driven from the outside of the container by means of a disk-shaped drive element, at least one of the facing surfaces of the container and the drive element being surface-structured.
  • Such a washing machine is known from EP 0 152 745 B1.
  • a pulley is used as a disk-shaped drive element for a laundry drum, which has a hub in the middle and a rim on the outside, on the outer surface of which a drive belt runs, which receives drive energy from a drum drive motor.
  • the hub and the rim of the pulley are connected by spokes; usually three wider or five scl smaller spokes are provided.
  • the washing machine still contains a tub as a container for laundry.
  • a laundry drum is horizontally and rotatably mounted in the tub. It is driven by the pulley via a shaft.
  • the back wall of the tub is folded in a meandering pattern, creating spoke-like structures that help stabilize the back wall.
  • the rear wall structure is represented by a supporting star made of cast steel, which forms a surface structure similar to that of the washing machine according to EP 0 152 745 B1.
  • the washing drums during the spin process at very high speeds for. B. driven at speeds beyond 1600 rpm, cause the brushing structures of the mutually facing surfaces of the drive pulley and the rear wall of the container together with the air located between them an organ-like noise that can be very disturbing.
  • the invention has for its object to design washing machines of the type mentioned in such a way that such disturbing noises can not arise if possible.
  • this object is achieved by the characterizing part of claim 1 in such a way that at least one of the two surfaces with a surface Chen structure comparative cover is provided.
  • the structures are decoupled from one another so that such disturbing noises can no longer arise.
  • a particularly advantageous embodiment of the invention in a Wascli machine with a serving as a drive element. Pulley from a rim leading the belt and a number of spokes connecting a hub to the rim, the spokes are provided with a flat cover.
  • the structuring given by the spokes of the surface facing the tub is covered with a uniform surface, which no longer causes air vibrations when the pulley is rotated, which together with the structure of the tub rear wall could build up into an audible airborne sound vibration.
  • a similar effect would result from another advantageous embodiment of the invention in a washing machine with a plastic tub which serves as a container and whose bottom facing the drive element is shaped as a surface-structured surface such that a meandering fold of the bottom wall results Spoke-like stiffeners of the floor result if the stiffeners of this washing machine are provided with a flat cover.
  • the cover can advantageously consist of a film, in particular a highly flexible plastic film.
  • the film can advantageously be fastened to the drive element or to the floor by means of mechanical means.
  • a clamping ring that can be attached to the circumference by means of catches can be provided for the film. This would have the advantage that the film is easily exchangeable.
  • the film can also on the most protruding structural surfaces, for. B. on the spokes of the pulley or on the stiffeners of the container rear wall, be glued to the respective structured surface.
  • FIG. 1 is a perspective view from the back of a Wascl machine tub with a pulley without using the measure according to the invention
  • Fig. 2 is a partial section perpendicular to the rear part of a tub according to Fig. 1 using the measure according to the invention.
  • the illustrated embodiment is based on a washing machine, the one Has plastic lye container 1 for receiving a horizontally mounted laundry drum 2 (Fig. 2).
  • the rear wall 3 of the tub is structured in a meandering shape, so that there are spoke-like stiffeners 4 which leave corresponding cavities 5 between them.
  • a pulley 6 is arranged, which is connected in a rotationally fixed manner to a support star 8 of the laundry drum 2 via a shaft 7.
  • the shaft 7 is horizontally rotatably mounted in the hub 9 of the tub wall 3.
  • the pulley 6 has a hub 10 which is rotatably connected to the shaft 7.
  • the hub 10 is connected to the rim 11 of the pulley 6 via five spokes 12, which in the example shown leave large gaps between them.
  • a flat covering of the respective structures is attached to at least one of the facing surfaces of the container 1 and the drive element 6.
  • a thin, e.g. B. film-like, cover 13 attached on the side of the pulley 6 facing the tub 1.
  • This coverage may already be sufficient to avoid the feared disruptions.
  • a single cover 14 of the rear wall 3 of the tub 1 may also be sufficient. If, however, one of the covers is not sufficient, both covers 13 and 14 can also be used so that there are no discontinuities in the surfaces which are swept by the entrained air.
  • the covers can be attached in a variety of ways.
  • the simplest way of attachment will be by gluing. But there are also purely mechanical types of attachment (screws, detents, plugging) conceivable, by which u. a. the covers can be replaced.

Abstract

L'invention concerne un bac à linge (1) d'un lave-linge comportant un système d'entraînement (2) de linge, pouvant être entraîné par l'extérieur (1) au moyen d'un élément d'entraînement (6) en forme de disque, au moins une des surfaces du bac (1) et de l'élément d'entraînement (6), orientées l'une vers l'autre, présentant une structure de surface. Dans le cas d'un tel bac à linge, il est possible que les structures de surface du lave-linge se comportent comme un générateur d'oscillations produisant des bruits gênants lors de l'essorage. Selon l'invention, le risque de production de tels bruits est au moins partiellement éliminé du fait qu'au moins une des deux surfaces (3) est pourvue d'un capot (13, 14) uniformisant la structure de surface.
