Definitions
- This invention relates to a washing machine drum according to the preamble of the claim. It affects in particular household washing machines with low water requirements.
- Said means are formed by a plurality of cups, which are attached to the side of the drum opening in the form of a ring around the washing drum and serve to pour washing water scooped out of the washing container into a collecting trough which is arranged above the opening of the washing container and one in the inside of the washing drum has a discharge opening.
- Circular pumping devices are attached to both drum end faces.
- Said scooping or pumping devices are equipped on the inside with several spirally curved pump blades or blades and each lead to a central inlet funnel.
- the devices mentioned form Archimedean centrifugal pumps that are virtually completely open on the circumference.
- the laundry drum is driven in both directions of rotation, therefore the scooping devices are designed so that their blades are curved in opposite directions, ie depending on the direction of rotation of the drum, one scooping device always works as a pump while the other remains ineffective.
- the invention also has the task of allowing a spin operation when the tub is full, in which, on the one hand, the rapidly rotating drum does not generate foam and, on the other hand, no alkali gets into the drum or onto the laundry items.
- a lye return device in the form of a scoop ring with scoop chambers arranged radially distributed on the washing machine drum end wall, the scoop ring diameter being larger than that Drum diameter is formed and this creates the possibility of scooping lye from the tub, the liquid level is below the lower edge of the drum.
- the scoop ring or its scooping chambers are closed on the circumference, but are provided on the face side with scoop chamber inlet openings and drum inlet openings.
- the scoop chamber inlet openings are arranged offset in relation to the drum inlet openings in such a way that lye is scooped out of the tub into the drum only during the left-hand drum rotation.
- 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 6 of the drum 2 can be sealed on the front of the device by a door glass 7 and a bellows 9.
- the tub drain 8 At the bottom of the tub 1 there is the tub drain 8.
- 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 closed outer circumference and a plurality of radial arranged scooping chambers 12, which are connected to the interior of the drum 2 via lateral inlet openings 13 made in the drum wall 4.
- scoop chamber inlet openings 15 which are offset from the drum inlet openings 13 located in the interior of the scoop chambers 12 are provided.
- the scoop chamber inlet openings 15 are arranged in a circle so that they just dip into filling levels 16 or 17. Both filling levels 16, 17 lie below the drum jacket 3. If the drum 2 now rotates counterclockwise, alkali is scooped through the inlet openings 15, 13 into the interior of the drum 2 and wets the laundry. The wetting process takes place in a relatively short time, since due to the large number of scooping chambers 12 per drum revolution, a relatively large amount of wash liquor gets into the interior of the drum.
- the scoop chamber inlet openings 15 are designed without accumulation edges, so that foam formation is prevented during intermediate spinning clockwise according to the direction of rotation 18 by the scoop ring 11 immersed in the lye or washing liquor. No lye can enter the scooping chambers 12 during the spinning. It only returns through centrifugal forces through the perforated drum jacket 3 into the tub 1, from which it is conveyed into the interior of the drum 2 with the aid of the scooping chambers 12.
- the scoop ring 11 can either be attached to the rear drum wall or to the drum wall 4 ′ facing the filling opening 6.
