Definitions

  • the invention relates to a drum washing machine according to the preamble of claim 1. It relates in particular to household washing machines with extremely low water, detergent and energy requirements.
  • Such a drum washing machine is known from DE-OS 36 31 724 and DE-OS 35 27 724.
  • washing is carried out at the lowest possible washing level with the help of perforated drum ribs, which are also designed as scoops for the free liquor.
  • DE-OS 37 38 049 a "front loading washing machine” is known, which is equipped with a return device with means for lifting the washing water.
  • the means are formed by a plurality of cups which are fastened on the side of the drum filler opening in the form of a ring around the washing drum and serve to pour washing water drawn from the washing container into a collecting trough which is arranged above the opening of the washing container and one has an emptying opening pointing into the inside of the washing drum.
  • the laundry drum In all cases, however, the laundry drum must be continuously immersed in the free liquor so that the scoops or beakers are filled for the purpose of wetting the laundry items. This means that a relatively high level of suds is still required in the wash tub or in the laundry drum itself.
  • the invention has for its object to design the laundry drum in such a way that alkali wetting of the laundry items takes place even at a tub level which is below the lower edge of the laundry drum; i.e. wetting of the laundry is made possible without the rotating laundry drum being immersed in the lye, or lowering the lowest possible washing level compared to the prior art.
  • a drum 2 with its drum casing 3 and the drum walls 4, 4 ' is rotatably mounted in a tub 1.
  • drum ribs 5 which are used to take the laundry items.
  • the filling opening of the drum 2 can be sealed on the front of the device 6 by a door glass 7 and a bellows 9.
  • the rear of the tub 1 is designated by 10.
  • a peripheral scoop ring 11 is arranged on the drum wall 4, the outer diameter of which is larger than that of the drum shell 3.
  • the scoop ring 11 has a plurality of radially arranged scoop chambers 12 which are connected to the inside of the drum 2 via lateral inlet openings 13 provided in the drum wall 4 or 4 '. formed, the open ends of which are slightly bent up.
  • scoop chamber inlet openings 14 which are open radially downwards.
  • These scoop chamber inlet openings 14 lie outside the diameter of the drum shell 3 and either immerse fully in the maximum filling level 16 or just in the minimum filling level 17 of the wash liquor. Both filling levels 16, 17 lie below the drum jacket 3.
  • FIG 3 shows a further version of a scoop ring 11.
  • the scoop ring 11 has a closed outer diameter.
  • the scoop chamber inlet openings 15 are provided on one or both sides 19, 20 of the scoop ring 11. They are arranged in a circle so that they just dip into the minimum filling level 17. As previously described, the liquor enters the interior of the drum 2.
