Definitions

  • the invention relates to a washing machine with a horizontally rotatably driven in a tub laundry drum and arranged on the inside of a drum shell, hollow carriers, each having a driver base in the course of the drum shell, is introduced into the at least one inlet opening, wherein proportions a lye located in the lower vertex of the tub in the cavity of the driver flow through the corresponding inlet opening and after further rotation of the laundry drum in a raised position of the driver from the cavity via outlet openings in the ridge area of the driver remote from the driver base in the interior of the laundry drum pour out, as well as a method of operating the washing machine.

In this arrangement, however, the entrained liquor volume of the driving ribs is comparatively small.
  • This object is achieved by a trained according to claim 1 washing machine in such a way that in the cavity from the Mit Converse Camill ago in the direction W of the inflowing liquor ascending, solid barrier is present, which forms an open chamber within the cavity behind, and that the upper edge of the barrier in the lowest position of the driver is higher than the level of the liquor and the chamber located behind the upper edge can be filled with lye on further rotation of the laundry drum by overflowing the barrier.

Due to the fact that the chamber can be filled beyond the filling level of the liquor supply and generally shows a good retention effect, a comparatively large amount of liquor can be carried along and poured out over the laundry. Due to the thus increased washing effect per unit time (washing efficiency), a shorter program time can be achieved, which in turn allows a reduction of the heating time and thus the energy consumption. On the other hand, alternatively, the total amount of the wash liquor can be reduced, which also causes a reduction in energy consumption and also water consumption because of the lower heating power required.

Abstract

L'invention concerne une machine à laver comprenant un tambour de lavage (4) entraîné horizontalement de manière rotative dans un bac à lessive (1) et des éléments d'entraînement creux (11') disposés sur la face interne d'une enveloppe de tambour (41), qui présentent respectivement dans le prolongement de l'enveloppe de tambour (41) un fond d'élément d'entraînement (42), dans lequel au moins une ouverture d'admission (14') est réalisée. Une proportion de la lessive se trouvant en bas du bac à lessive (1) s'écoule par l'ouverture d'admission (14') vers l'espace creux (13') de l'élément d'entraînement (11'). Suite à une rotation supplémentaire du tambour de lavage (4) avec une position élevée de l'élément d'entraînement (H'), cette proportion s'écoule par les ouvertures de vidange (15) dans la zone de faîtage de l'élément d'entraînement (11') à l'intérieur du tambour de lavage (4). Grâce à la conception selon l'invention de l'élément d'entraînement (11'), le mouillage peut être réalisé de manière plus intensive que dans le cas de machines à laver utilisées jusqu'à présent et son processus exige moins de temps.
