Definitions

  • the invention relates to a laundry treatment machine, in particular a washing machine with spin cycle and a spin dryer, according to the preamble of claim 1.
  • Such a laundry treatment machine is known from DE 37 38 388 A1.
  • she shows a bellows cuff with a loop-shaped fold and extends between a housing opening and a tub opening as a feed channel to a laundry drum, which is arranged in the tub.
  • a fastening section which has a side wall of a cuff fold forms, are axially parallel to the cuff center axis one or more emptying openings formed to drain lye from the cuff fold. With that allows an essentially complete drainage of the cuff into the tub become.
  • EP 0 752 493 B1 shows a front loading washing machine with one loading channel for a washing drum forming bellows sleeve between one Housing opening and a tub opening.
  • the laundry drum jacket is on its inner circumference with blades or the like, which lye from the Feed the drum into the cuff.
  • the cuff fold is in a bottom wall a vertical return opening is formed, to which an extending downward Alkaline return hose is connected, the lower end of which is connected to the lower end is connected to a sump, which is connected to an overlying one via a drain hose Drain opening of the tub is connected at its lowest point.
  • a drain pump hose connected to a drain pump.
  • the cuff In the return opening the cuff is formed a seat for a lint filter. This is higher than that Lye level in the tub, so that from the laundry drum to the lint filter centrifuged lye by gravity through the filter and then through the Swamp can flow back into the tub.
  • a lint filter In laundry operation finds a constant recirculation of the lye through the lint filter instead, filtering out lint. This is to avoid that a lint filter is required on the suction side of the drain pump of the pumping line in the lower washing machine area is difficult to access for cleaning.
  • the present new invention deals with a subject which is in the prior art was not recognized and is also not solved by the prior art.
  • Rotation of the laundry drum occurs crosswise in the tub and in the cuff to the axis of rotation and thus also transverse to the longitudinal axis of the cuff vibrations.
  • These vibrations are at spin speeds to dry the laundry in the Washing drum particularly strong (high frequencies, accelerations and vibration amplitudes).
  • These vibrations cause part of what is trapped in the cuff Water from the cuff into the laundry drum and thus onto the laundry thrown back into it before passing through the emptying opening formed in the cuff or drain opening can drain. This is also known as the "fountain effect".
  • this rewetting has the consequence that the The drying process of the laundry takes longer and therefore also consumes more energy becomes.
  • the object of the invention is to solve the drying process and the Reduce energy consumption when spinning laundry to dry it.
  • the cuff is preferably a bellows cuff that is at least one behind has a cuff fold on the outside, and the emptying opening is in the fold base formed in a bottom wall of the cuff fold. This will make bellows cuffs ensures that the mentioned fountain effect also in the cuff fold is avoided.
  • a drain line extending downward is preferably at the drain opening connected. Because the drain line does not cross, but stretched downward, becomes a in the direction of vibration of the cuff Achieved faster water drainage from the drain opening.
  • the drain line can be placed under the drum opening in the tub have outlet opening and / or one below the laundry drum in the Have tub opening opening and / or one below the tub have an outlet opening into a drain line of the tub. Thereby a safe drainage of the liquid is achieved over a short conduction path, whereby it is automatically mixed with the liquid coming from the washing drum in the tub is thrown out.
  • the invention results in an essentially vertical discharge of the liquid (Lye, water or the like) through the emptying opening of the cuff.
  • the emptying opening can be formed by a nozzle molded onto the cuff or by a separate hose can be formed. Because this means on the one hand the direction of force of the vibrating Cuff on the liquid and on the other hand the nozzle direction or Hose direction are essentially the same direction, the liquid can with high acceleration forces drain completely quickly without the water coming out of the cuff fold is thrown back onto the laundry in the laundry drum.
  • the front loading laundry treatment machine shown is a washing machine without, but preferably with a spin cycle. It could also be a spin dryer. It contains a preferably bellows-like sleeve 2, which has a front housing opening 4 of a housing 6 with a front tub opening 8 of a Tub 10 connects and a feed channel 12 to a drum opening 14 forms a laundry drum 16 which in the tub 10 around a horizontal Axis of rotation is arranged rotatably.
  • cuff 2 In the cuff 2 is in the cuff bottom 20 at the lowest point between the tub opening 8 and the housing opening 4 a substantially vertical, for Liquid (lye, water and the like) unobstructed discharge opening 22nd formed for emptying the cuff 2.
  • the sleeve 2 is preferably a bellows sleeve, the at least one cuff fold 24 which is Z or S-shaped in axial section has, wherein the drain opening 22 in the fold base in a bottom wall 20 of the Cuff fold 24 is formed.
  • the drain opening 22 can be through the upper end of a drain hose or an emptying nozzle molded or connected to the bottom wall 20 26 or be formed in some other way.
  • the drawings show one of the Drain opening 22 downwardly extending drain line 28, the upper End portion is formed by the drain port 26.
  • the emptying opening 22 and thus also the nozzle 26 extend on the upper one End section of at least 5 cm substantially vertically downwards, with their Direction preferably does not deviate from the vertical by more than 30 °.
  • the lower end portion of the drain line 28 a first outlet 30, which is below the laundry drum 16, but above an outlet opening 32 opens into the tub 10, at its lowest point the drain opening 32 is formed. Furthermore, the drain line 28 has its lowest End of a second outlet 34, which is connected to an outlet 32 Alkaline drain line 36 is connected and opens into this.
  • the cuff 2 has a fastening section connected to the tub opening 8 38, from which a fold wall 40 extends upwards, the upper one End portion protrudes into the drum opening 14 and which the fold interior 42 to Suds container opening 8 limited.
  • additional emptying openings 44 may be formed connect the pleat interior 42 horizontally to the tub opening 8 in order to the fold interior 42 liquid through the tub opening 8 into the Derive tub 16 below the drum opening 14.
  • additional drainage openings 44 designated openings are known from the prior art. They are in addition to those formed essentially vertically in the pleated base 20 Drainage openings 22 are not absolutely necessary, but can be used for drainage support from the membrane fold 24.
  • FIGS. 2, 3 and 4 are with the exception of the following Features identical to the embodiment of Fig. 1:
  • the drain line 28 only the outlet 34 at its lower end, which in the lye drain line 36 opens.
  • the drain line 28 has only that at its lower end Outlet 30, which is below the washing drum 16, but above the drain opening 32 opens into the tub 10.
  • the drain line 28 has only the lower End of a lower outlet 46, which on the suction side of a drain pump 50 in a pump down line 48 opens.
