Definitions

  • This invention relates toimprovements in washing machines having a washing drum continuously driven in one and the same direction of rotation, for instance, by a universal motor with reduction gear.
  • the articles to be laundered have the tendency of forming one compact mass which is moved around as a whole, thus preventing a good washing effect on the individual articles.
  • the object of the present invention is to remove this deficiency and, more in particular, to design the vane of the washing drum in such a manner that it entrains during the rotation of the drum all articles placed in the washing liquid contained in the lower part of the drum and causes the same after it has reached the highest position to fall one after the other into the washing fluid.
  • the washing drum of a washing machine is provided with one single vane, the surface of which, viewed from the drum axis, is so bent that every article upon reaching its highest position is placed on a portion of the vane which is inclined about 30 with respect to the horizontal.
  • the vane may have approximately a semi-circular shape and forms with'the portion of the inner drum wall opposite to the convex side of the vane a chamber which is closed at the end of the vane oppo- .30 site to the direction of rotation by a partition wall.
  • the space enclosed by the vane may be closed by a cover with respect to the inner space of the washing drum.
  • Figs. 1 through 5 illustrate an embodiment of the invention in five subsequent operating positions, the washing drum being shown in cross sectional views.
  • Fig. 6 exemplifies a second embodiment of a washing drum according to the invention.
  • the washing drum l I comprises a drum cylinder ll rotatable about journals I! in the direction of the arrow 13, and a lid l covering an opening through which the articles to be washed are placed in and removed from the drum.
  • a vane It extends from the inner wallof the drum beyond the axis of rotation and forms with a-portion of the drum a pocket-like chamber l which collects the articles to be washed during the rotation of the drum.
  • the vane 14 is so bent that the chamber l5 has approximately semi-annular shape.
  • FIG. 1 shows the washing drum in a position wherein all the articles to be washed are entrained in the pocket l5. Shortly after, the first article l9 will drop out of the pocket into the washing liquid.
  • the drum In the position shown in Fig. 2 the drum is rotated to such an extent that about the half of the articles contained therein has fallen from the chamber l5. Since the articles are all arranged in series in the chamber The chamber now begins to take up the articlesat the lowest point of the drum.
  • Figs. 4 and 5 show further positions of the drum in which the articles are completely taken up and are conveyed upon a further rotation of the drum to the highest point of the drum.
  • the articles placed on the bottom of the washing drum are again entrained by the vane chamber and fall as soon as they have reached the highest point one after the other from said chamber into the washing liquid without balling. In this manner, it is possible to attain with a washing drum rotating always in the same direction the best and the most rapid washing of the-articles.
  • washing drum has a perforated wall and is arranged in a container filled with washing liquid
  • the drum may also be designed without perforations so that a special washing fluid container may be dispensed with.
  • a single vane forming part of said drum and extending from the inner wall of said drum beyond the drum axis so as to have one end abutting against the wall of the drum while its other end is spaced from said wall in order to entrain the articles to be washed, said vane having the portion of its operative surface which is near said axis curved concentrically with respect to said axis so as to spill subsequently the individual articles entrained when in operation.
  • a single vane mounted in said drum extending from the inner wall of said drum beyond the drum axis so as to have one end spaced from said inner wall in order to form a curved pocket for entraining the articles to be washed, said vane having a substantially semi-cylindrical surface portion adjacent to said spaced end sothat when the drum is in operation the entrained articles rest on differently inclined areas of said surface portion, and the area of said surface portion having passed beyond the highest position in the drum is inclined downwardly and outwardly relative to said pocket so as to cause spilling of the article resting on said latter area while the remaining area of said surface portion is inclined towards the bottom of said pocket.
  • a single vane in said drum extending from the inner wall of said drum beyond the drum axis so as to have one end spaced from said inner wall, said vane having an essentially semi-cylindrical portion arranged concentrically with respect to said drum, and an approximately radial portion between said semi-cylindrical portion and the inner wall of said drum.
  • a single vane in said drum extending from the inner wall of said drum beyond the drum axis so as to have one end spaced from said inner wall, said vane having the portion of its KARL BLASE.
