Definitions

  • the invention relates to a cuff for a laundry treatment machine and a laundry treatment machine with such a cuff.
  • a laundry treatment machine is understood to mean a machine which is intended for the treatment, in particular care, of laundry. It may thus be a washing machine or a laundry drying machine, or a machine intended both for washing and for drying laundry, also referred to as a "washer-dryer”.
  • a laundry treating machine in the form of a washing machine or a washer-dryer has a housing which forms an exterior or enclosure (and as such, and in a corresponding sense, a "frame") of the laundry treating machine.
  • the housing has a front or upper opening for loading and unloading laundry. The opening can be closed by a door.
  • a tub is arranged, which contains water and detergent for washing the laundry during washing.
  • a drum is installed inside the tub. The drum is loaded with the laundry to wash the laundry. For washing, the drum is filled with water and the cleaning agent and rotated about a rotation axis. The drum is driven to rotate by a motor or the like.
  • a collar (also referred to as a "seal ring") can be labeled between the tub and the housing, even given that the shape of the collar is in the usual shape Torus or circular ring can vary greatly) arranged.
  • This sleeve is made of an elastomer and also serves to damp vibrations generated by the rotation of the drum, especially at high speed.
  • the WO 2007/063072 A1 discloses a cuff for a washing machine.
  • the cuff has a front flange and a rear flange. Between the the front and the rear flange are two substantially U-shaped areas which connect the two flanges together.
  • the front flange is provided for mounting on the housing of the washing machine.
  • the rear flange is intended for mounting on the tub of the washing machine.
  • the front and the rear flange are formed continuously in the circumferential direction.
  • the collar has on the rear flange an area which extends in the radial direction inwards. During operation of the washing machine, the drum rotates in loose sliding contact in this area.
  • the tub may have in its front region a circumferential and substantially J-shaped rib. To install the cuff, it must be pulled over the rib of the tub.
  • the sleeve which is usually made of rubber or other suitable rubber-elastic material, a rib, which serves for attachment to the tub.
  • This type of cuff is easier to mount, but does not have the resistance to rotation such as the previously described cuff.
  • the cuff which can be arranged between a housing and a tub of a laundry treating machine, has a first flange which can be mounted on the housing, and a second flange with a plurality of circumferentially spaced recesses which on the Lye container can be arranged or attached, on.
  • the sleeve is attached to the tub by the cuff is guided with their recesses over appropriately trained areas of the tub so that these areas engage in the recesses. By a subsequent rotational movement of the cuff this is releasably attached to the tub.
  • the invention is based on the idea to attach the cuff similar to a bayonet lock on the tub.
  • the sleeve can, at least in the region of the second flange, be made relatively rigid and, in particular, torsionally rigid and optionally have corresponding stiffening elements, since they do not have to be pulled with considerable elastic deformation over a rib or the like of the tub.
  • the cuff is not only very easy and reliable to assemble, but it can also better resist the forces and stresses occurring during operation of the laundry treatment machine.
  • the sleeve between the tub and the housing of the laundry treatment machine is firmly clamped.
  • Additional securing measures may be provided, for example a securing element or pressing element (eg a flexible wire) which presses cuff and tub together along the circumference of the cuff to fix the cuff to the tub.
  • the recesses are arranged evenly spaced in the circumferential direction, thus facilitating both the manufacture of the cuff and its assembly. There is no special alignment between cuff and tub required.
  • the flange has an annular region in which the recesses are arranged.
  • the annular region has a groove which extends in the circumferential direction, so that areas of the tub or of any connecting element arranged therebetween can engage in the groove and the collar is fixed and held particularly well by positive locking on the tub.
  • the groove is closed by lugs, a stop or a closure element at areas which are located in each case on one side of the recesses, so that during assembly there is no risk that the sleeve rotates out of engagement with the tub again.
  • the flange has a curved edge extending radially outwardly so that the collar on the tub can be replaced by an additional securing element (such as a flexible wire), e.g. is inserted into the curved edge, can be held.
  • an additional securing element such as a flexible wire
  • any securing means can be used which is suitable for holding the sleeve to the tub and a shape of the flange corresponding to the securing means can be provided.
  • the curved edge has at least one kind of lever or tab which extends substantially radially outwards, so that a rotational movement for mounting the collar is facilitated.
  • At least two positioning projections are provided on the flange, which in the mounted state of the sleeve on the tub in corresponding
  • the flange has at least one drain or drain hole (e.g., in the annulus area) so that water can be returned to the tub.
  • drain or drain hole e.g., in the annulus area
  • the laundry treating machine comprises a housing or other suitable stationary component and a tub, and the sleeve is arranged between the housing and the tub.
  • the recesses of the cuff are adapted to be engaged by corresponding portions (i.e., shaped portions) of a rib, collar, or protrusion of the tub; and the collar is rotatable in the circumferential direction of the same on the tub bayonet-like manner in engagement with this rib, so that therefore a simple mounting similar to a bayonet lock is made possible.
  • the tub on a rib which is formed as circumferentially spaced apart teeth, wherein in the mounted state of the cuff, the teeth are in a groove of a ring portion of the sleeve.
  • the rib is formed substantially T-shaped or has a T-shaped cross-section, and a flange of the sleeve surrounds a portion of the rib, which extends radially outwardly therefrom, so that the sleeve is securely held on the tub.
  • the collar has a curved edge on the flange, and the rib has a curved portion, wherein the edge and the curved portion extend substantially radially outward and the edge is in the radial direction on the outside of the curved portion; and a securing means or a pressing element, in particular a circumferentially extending wire, is arranged so that it presses the edge on this area, whereby the sleeve is held particularly well on the tub.
  • At least one drain hole is provided in a region of the rib, so that water or washing liquid can be returned to the tub again.
  • the rib has positioning grooves into which positioning projections formed on the flange grip, so that the collar is securely held in its end position.
  • a laundry drum is disposed in the tub so as to be slidably rotatable on a ring portion of the sleeve.
  • the drum may be arranged so that it is not in sliding contact with the annular portion of the sleeve, but that there is a gap therebetween which is sized so that items of laundry do not normally fit or pinch there. This latter arrangement can be chosen to avoid permanent friction between the ring area and the drum.
