Definitions

  • the invention relates to a washing machine, in particular a programmable household washing machine, with a rotatable washing drum for taking up laundry, whereby a Pipe system is in place with the wash liquor from the Area below the washing drum in the upper area conveyed to the washing drum and there onto the laundry in the washing drum can be sprayed.
  • a washing machine of the generic type is from DE 199 34 579 A1 known.
  • the one disclosed and described there Washing machine washes the laundry, which can be rotated Washing drum is added.
  • To achieve an efficient Washing process is provided that by means of a. line system Wash liquor from the tub, which itself located below the washing drum, in the upper area conveyed to the washing drum and from there onto the laundry is injected. Good wetting or Flooding the wash items with the wash liquor. Nevertheless becomes Carrying out the washing process only a relatively small volume Consumes water, so the generic washing machine also to be judged positively in ecological terms is.
  • the invention is based on the object to further develop a washing machine of the type defined at the outset, that if the efficiency of the Washing process reduces foam formation.
  • the fanned out spray of the Wash liquor has only a small mass based on the area, on which he descends. Has foam formed larger foam bubbles due to the fanned-out spray crushed and thereby foaming the washing machine effectively prevented.
  • deflected and fanned out jet of the wash liquor an optimal flooding of the laundry through the wash liquor achieved.
  • the means have a Leitform Nursing that the from the pipe system outgoing jet of the wash liquor at least in one direction can deflect by a predetermined angle; prefers it is envisaged that the guide fitting the beam of Wash liquor deflected in two mutually perpendicular directions.
  • the angle of the deflection it has found to be advantageous that this at least 60 °, preferably 90 °.
  • a particularly good washing result can be achieved if the pipe system in the end. range of the wash liquor is essentially radial Feeding the washing drum direction and the means for deflecting the beam at least partially in the axial direction of the guard drum and / or deflect in the circumferential direction of the washing drum.
  • the guide shaped piece for Deflection of the jet in the circumferential direction of the washing drum extends symmetrically from the end region of the line system.
  • a simple manufacture of the lead fitting at simultaneous high efficiency of the deflection process of the fleet jet can be created in that the guide fitting in the end area of the pipe system in one cut in the axial washing drum direction and in the radial washing drum direction runs, essentially. the shape of a Quarter circle. It is particularly advantageous if the baffle is becoming flatter in the circumferential direction, d. H.
  • the axial washing drum direction and the radial washing drum direction runs from the end of the pipe system based on the shape of the quarter circle mentioned in Circumferential direction is steadily flatter.
  • expansion of the baffle has proven to be favorable if it extends over a circumferential angle between 20 ° and 60 °.
  • the baffle in the form of a reflector is particularly advantageous executed.
  • a washing machine 1 can be seen schematically in FIG arranged a rotatable washing drum 2 in a known manner is.
  • a line system leads from the washing drum 2 3 to the tub 11, which is below the washing drum 2 is arranged.
  • a line system 4 in the area above the washing drum 2.
  • a feed pump 12 is arranged in this pipe system 4.
  • FIG 2 it can be seen that the line system 4 in the end region 7 in the radial washing drum direction R (here: in the direction the vertical) enters the area of the washing drum 2.
  • the baffle 8 deflects the wash liquor jet the radial washing drum direction R by 90 ° in the axial Washing drum direction A by the deflection angle ⁇ , the present Is 90 °.
  • FIG. 4 is a top view of FIG Washing drum 2 shown. 5 shows the associated top view.
  • Baffle 8 has the shape of a reflector (see in particular FIG 5). This ensures that a uniform Spraying the laundry with washing liquor can be achieved can, if this via the line system 3, 4 in the area the washing drum 2 enters.
  • ⁇ is the circumferential angle ⁇ , over which the Baffle 8 extends in the circumferential direction of the washing drum 2, approx. 45 °.
  • FIG 6 shows the sectional view according to section A-B according to FIG 4. This is the section at the height of the Line system 4.
  • the baffle 8 is so in this area trained that it is essentially the shape of a quarter circle 9 has.
  • the shape of the guide plate 8 results in deflecting the jet of the wash liquor so that the entire Wet the inside of the washing drum and thus the Laundry is optimally supplied with liquid.
  • the wash liquor is the Foam formation in the washing drum 2 minimal.
