Definitions

  • the invention relates to a washing machine with reduced rewetting and a preferred method for its operation.
  • the invention relates to a washing machine for the treatment of laundry with a program control, a water supply system, a rotatably mounted drum in a tub and a drive motor for the drum, wherein structures on the drum and / or in the tub influence the air flow, and a particularly suitable method to operate this washing machine (see DE-20 2009 000376 U ).
  • a washing program generally has a rinsing phase with several spinning steps after a wetting phase and a washing phase.
  • the centrifugal force forces the water from the laundry through drainage holes of the drum to the outside into a space between the drum and the tub, where it ideally flows into a lower part of the tub, a region comprising a heater, also referred to as a "heater bag" , From the radiator pocket, this water can then be pumped out for disposal or reuse.
  • a heater also referred to as a "heater bag”
  • the drum thus gives due to their rapid rotation of the amount of air, which is located in the space between the drum and tub, a tangential pulse in the direction of rotation of the drum.
  • a tangential pulse in the direction of rotation of the drum.
  • the water exiting through the perforated drum also leaves the drum in the tangential direction, i. In tangential direction, there is an additional, dependent on the actual water flow contribution to the tangential pulse.
  • a circular circulation of the amount of air is obtained in the space between the drum and tub, which affects a forming on the inner wall of the tub water ring.
  • a certain amount of water instead of being landed in the radiator pocket for pumping, is circulated on the inside of the tub (also referred to herein as the "side tub wall") as a so-called water ring.
  • Known measures for deriving this water ring and thus to reduce the re-wetting are introduced into the tub form elements.
  • This air flow entrains water droplets, for example from the surface of the water ring, so that the water ring is more like a wild spray than a compact amount of water and thus has a correspondingly large surface area.
  • water droplets are in particular entrained from the water in the radiator bag. This effect is more pronounced when due to uneven, i. unbalanced, rotation of the drum, which may arise, for example, by an uneven distribution of the laundry in the drum, water droplets are thrown from the radiator pocket.
  • the water droplets are drawn perpendicular to the air flow according to the velocity gradient in the flow (Bernoulli or Venturi effect) and thereby entrained in the longitudinal direction with the flow.
  • the water droplets entrained with the air flow can in particular pass back to the laundry via the drum gap and thus bring about rewetting of the laundry, which thus has an increased residual moisture content.
  • a disproportionate time and energy-consuming spin would be required, especially as the amount of water still in the system is progressively withdrawn slowly as the spin progresses.
  • the EP 1 050 616 A1 describes a method for spinning in a washing machine, in which the reduction of the speed (“Abtouren”) after the spin is not carried out with high negative acceleration, but the steepness of the Abtourrampe is reduced, to avoid that the water ring coincides during Abtouren and dripping on the drum. A rewetting by the amount of water during the Skidding passes through the described air flow over the drum gap on the laundry, this is not avoided.
  • the DE 197 52 512 A1 describes a washing machine with a washing tub rotatably arranged in a tub around a horizontal axis, wherein in the washing drum shell outwardly or inwardly directed formations are present.
  • the DE 10 2005 026 175 A1 describes a water-leading household appliance, such as a washing machine, with a rotatably mounted laundry drum with a drum shell and at least one drum top surface, wherein imprints are applied to the laundry drum, wherein the edges of the embossments are formed elliptical.
  • a washing drum for a washing machine which is provided via a cylindrical shell with a plurality of holes for the passage of working fluid. Between these holes trough-like characteristics or elevations are provided.
  • the DE 102 05 306 A1 describes a drum washing machine with a laundry drum whose shell is perforated, and which is surrounded by a container within which it is mounted on its rear wall at least horizontally flying, and with a working section for spin-drying the laundry located in the drum.
  • this drum type washing machine provision is made for substantially no air to flow from the container through the interior of the drum and back to the container during spin-drying.
  • a precaution for example, is a barrier disposed in the annular gap between the charging opening of the drum and the front opening of the container.
  • another measure is that the drum shell on a ring section, which is attached to the rear wall of the drum adjoins, at least a smaller specific hole area portion than on the closer to the feed opening arranged ring section.
  • the DE 20 2009 000 376 U1 describes a washing drum for a washing machine, the cylindrical shell has a plurality of flow holes and attached to the outer side of the washing drum compression space paddles.
  • the blades When spinning after the rinse and pumping out the rinsing liquid, the blades generate a negative pressure due to their wedge shape, so that the moisture in the laundry is exposed not only to the centrifugal forces but also this negative pressure.
  • the object of the present invention was to provide a washing machine in which the treated laundry has a reduced residual moisture after spinning.
  • the invention has for its object to provide a method for operating this washing machine.
  • the invention thus relates to a washing machine for the treatment of laundry with a program control, a water supply system, a rotatably mounted drum in a tub and a drive motor for the drum wherein on a drum surface and / or a side tub wall in a space between the drum and the tub outwardly projecting structures are arranged, which generate upon rotation of the drum about a substantially horizontal axis of rotation directed towards a rear suds container wall axial air flow, with protruding structures are those which from the Surface of the drum or the side tub wall protrude into the space.
  • the protruding structures on the drum surface and / or the side tub wall have an incline with respect to the axis of rotation of the drum increasing from the back tub wall toward the door of the washing machine.
  • the term "generating a directed toward a rear tub wall air flow” is interpreted broad and includes in particular directed toward a rear tub wall axial air flow component, which counteracts a usually directed forward to the door of the washing machine axial air flow component.
  • a reduced axial flow in the direction of the door is obtained, a quiescent state when both components cancel, or an axial air flow directed towards the rear suds container wall.
  • no axial air flow occurs in the direction of the door of the washing machine more.
  • the protruding structures form a helical structure.
  • the protruding structures are lamellas, in particular helically arranged lamellae.
  • the term "fin” herein generally refers to thin, long slices or leaves which may be flat or tortuous.
  • the protruding structures are regularly arranged in a ring around the drum surface.
  • a plurality of rings of protruding structures can be used.
  • the protruding structures eg lamellas, are preferably larger or provided with a greater pitch of the structures than in a rear area of the drum surface.
  • the protruding structures are disposed in a front half of the drum surface and / or a front half of the side tub wall.
  • lamellas are arranged on the drum surface and on the lateral tub wall as outwardly projecting structures.
  • the lamellae on the drum surface can be spaced axially and / or radially away from the lamellae on the lateral lye container wall.

  • the protruding structures on the surface enhance radial air flow.
  • the protruding structures are therefore chosen such that a radial flow around the drum is at least partially converted into an axial air flow directed towards the rear tub wall.
  • a rotating air mass is then at least partially reshaped by the lamellae located on the inside of the tub, in particular the lateral tub wall, into an axial flow.
  • the protruding structures in particular lamellae, on the drum surface and on the side tub wall wall in terms of number, arrangement, shape and / or size during the rotation of the drum in their influence on the air flow complement each other such that greater axial flow towards the rear tub wall results.
  • the protruding structures in particular lamellae, on the drum surface and on the side tub wall wall in terms of number, arrangement, shape and / or size during the rotation of the drum in their influence on the air flow complement each other such that greater axial flow towards the rear tub wall results.
  • a radial flow around the drum is converted into a flow directed towards the rear tub wall.
  • protruding structures particularly lamellae
  • their arrangement, size and number are generally similar.
  • the direction of inclination of the structures on the drum surface is usually opposite to that on the side tub wall.
  • beads are arranged on the drum surface as outwardly projecting structures.
  • externally embossed helical beads can be incorporated into the drum.
  • drainage holes are arranged on the drum surface with arranged obliquely to the axis of rotation of the drum tulips as protruding structures.
  • the drainage holes can be suitably shaped for this purpose, eg elliptical.
  • tulips are understood in particular to be outwardly directed collars, eg funnel-shaped collars. These can be shaped such that preferably tulips arranged helically on the drum surface be present and achieve a desired effect according to the invention in this way.
  • these tulips can advantageously lie in the direction of lamellae also used on the drum surface.
  • the tulips are preferably used as a supporting measure, e.g. together with lamellae on a side lye container wall.
  • punched sheet metal parts can remain on one side of the drainage holes and be used as outwardly projecting structures in the context of the invention.
  • a seam closing the drum can be designed as a spot weld with bent sheet metal ends as structures projecting outwards.
  • a drum is made by bending a sheet and welding the sheet ends together.
  • Such a seam can be provided obliquely in the blank of the sheet, so that it runs in the finished drum helically on the drum surface.
  • Such seams can also be incorporated several times, preferably three times, in the drum shell.
  • additional protruding structures can be incorporated as a correspondingly shaped blind seam. These would be, for example, in the drum shell inflected ribs.
  • the suds container wall in particular the lateral suds container wall, can be suitably structured in order to facilitate an outflow of the water located on it and / or to reduce the velocity of an air flow on its surface.
  • the structuring of the tub interior side can be achieved by various protuberances or recesses or by the arrangement of at least one component on the tub wall. For example, grooves or beads would be conceivable as depressions.
  • less drainage holes may be provided than in the middle, since in these areas the holes are highly permeable to air in all probability the middle of the drum when hurling the Wäschering the local drainage holes covered.
  • the air circulation should be reduced overall.
  • the drum gap can be narrowed, for example, by a suitable construction of the sleeve, wherein the drum gap is narrowed, in particular in the areas of the presumed remindbefeuchtungs inflow.
  • the invention also relates to a method for operating a washing machine for the treatment of laundry with a program control, a water supply system, a drum rotatably mounted in a tub and a drive motor for the drum, wherein on a drum surface and / or a side tub wall in a space between the drum and the tub outwardly projecting structures are arranged which generate upon rotation of the drum about a substantially horizontal axis of rotation directed towards a rear tub wall axial air flow, with protruding structures are those which from the surface of the drum or the lateral LaugenITAerwand protrude into the intermediate space, and wherein the protruding structures on the drum surface and / or the side tub wall have a pitch, relative to the axis of rotation of the drum, which from the rear tub wall in Direction towards the door of the washing machine increases.
  • the drum is operated in the last spin step at a speed above the compensation speed. That is, in particular, that the rotational speed is so high that an axial air flow is present in the direction of a rear tub wall.
  • This can be reduced, for example, a reinforced re-wetting during the reduction of the rotational speed of the drum during Abtouren, since the air flow takes a long time axially towards a rear tub wall.
  • the washing machine according to the invention has the advantage that the axial flow of the air, which is usually directed forward in the direction of the door of the washing machine, can be compensated. This makes it possible to return water to laundry in the drum, i. a rewetting, reduces and thus improves the residual moisture. In this way, the drying process of the laundry following the washing can be considerably shortened without the need for prolonging the spinning step. This is very advantageous for reasons of economy and environmental protection. As part of the air flow is eliminated, a saving of energy, a longer life of the engine and other machine components can be achieved. In addition, the operation of the washing machine with a lower required drive power, larger accelerations, especially in the higher speed range, and in embodiments also a reduction of flow noise is possible.
  • the radial flow can be significantly reduced, so that the formation of a continuously moving in a circle water ring can be counteracted to the tub wall.
  • the water produced during the spin phase can be better dissipated.
  • a spin phase can be shortened in time. This also makes the components of the Washing machine (especially drive motor and bearings) spared and it is consumed less energy.
