  • the treatment brushes involve components of the treatment module which, during the course of a treatment of a laundry item to be treated, come into contact with the laundry item at bristles or bristle-like protruding elements, in order to introduce mechanical stresses into the laundry item and thereby to reduce folds/creases at least partially.
  • the bristles or the bristle-like elements preferably consist of an elastic plastic material.
  • the treatment module is preferably embodied to be accommodated movably in the laundry treatment device, in order to realize an at least one-off movement of the treatment module along the laundry item to be treated during contact of the treatment brushes with the laundry item and, in doing so, to bring about the smoothing of the laundry item here.

  • the brushes of the at least one pair are in this case permanently positioned in relation to one another in the treatment position, while in an alternate variant to this, a positioning of the treatment brushes of the at least one pair in the treatment position from another position is able to be shown.
  • This type of embodiment of a treatment module has the advantage in this case that, in the two-sided contact of the brushes of the at least one pair with the laundry item which takes place in the treatment position, mechanical tensions are also introduced into the item of clothing on both sides and accordingly a reliable smoothing of folds/creases can be achieved.
  • a permanent positioning of the brushes in the treatment position allows a simple structure of the treatment module, wherein this variant is especially realized when only one movement along the laundry item to be treated with the treatment module is to be carried out.

  • the two aforementioned variants can be combined with one another by at least one pair being formed by round brushes and at least one pair by brush strips.
  • the use of a number of pairs of brushes has the advantage that this enables them to move in the widest variety of areas along the laundry item to be treated and smooth it in doing so.
  • the pairs of brushes are aligned in this case so that treatment brushes of one or more pairs with their longitudinal axes or axes or rotation are aligned in a horizontal direction and thus in a width direction of the laundry item to be treated, while the treatment brushes of one or more further pairs with their longitudinal axes or axes of rotation are oriented in a vertical direction and thus in a height direction of the laundry item to be treated.
  • bristles of the individual brushes are each inclined away from a central plane of the brush. In an advantageous way a spreading out of the laundry item between them in the width direction of the brush is achieved, which improves the smoothing effect.

  • An advantageous possible embodiment of the invention which in this case can be used as an alternative or also in combination with one of the aforementioned forms of embodiment, is that one treatment brush is part of two pairs, in which, in the treatment position, this treatment brush simultaneously lies opposite two other treatment brushes.
  • this treatment brush is thus simultaneously involved in two pairs of treatment brushes, which on the one hand has the advantage that thus different pairs can be formed with a lower number of treatment brushes.
  • the effect is produced that the contact areas of the treatment brushes with the laundry item to be treated increase, which enhances the smoothing effect that can be produced.
  • the treatment brushes of the at least one pair are each accommodated in an assigned part of the frame, wherein the frame parts are able to be moved for positioning the individual treatment brushes in the treatment position.
  • this enables the positioning of the individual treatment brushes in the treatment position to be realized, wherein a positioning of the individual treatment brushes via the frame part in a position differing from the treatment position, in which these cannot come into contact with a laundry item placed between the treatment brushes of a pair, is then possible as well.
  • the frame parts of the treatment module can be moved relative to one another in this case in order to move the frame parts towards one another or away from one another and thereby to initiate or to exclude an assumption of the treatment position of the treatment brushes.

Then, in the course of the smoothing process, the treatment module and a hanging facility accommodating the laundry item to be treated are moved relative to one another.
  • the laundry item is brought into contact with the treatment brushes in the course of the smoothing process at least once, either over its complete surface or over a part of its surface in each case.
  • a multiple contact between the treatment brushes and the laundry takes place by the treatment module and thus also the treatment brushes being guided a number of times over the laundry item to be treated.
  • the treatment brushes in this case can preferably be moved individually out of the treatment position in order, in the course of a backwards movement of the treatment module relative to the laundry item to be treated, to avoid any undesired contact between the treatment brushes and the laundry item.
  • One possible advantageous embodiment of the invention is that the introduced laundry item and the treatment module having round brushes are moved relative to one another in the course of the smoothing process, wherein the individual round brushes of the treatment module are rotated in this case at a speed of rotation that corresponds to a rolling motion speed of the round brush at the laundry item in the course of the relative movement of the treatment module relative to the laundry item.
  • This has the advantage that hereby wear on the item of clothing is avoided, which accordingly protects the material of the laundry item to be treated.
  • a pressure plate for example, a pressure plate moving along with the treatment module and thus with the brush can also be employed.
  • the latter could then also be shaped to correspond to the brush, such as with a (flat) cylindrical recess for a round brush pressing onto to it from opposite to it.
  • a pressure plate for the treatment could also be placed in a fixed location or movably in an inner area of the laundry item to be treated, wherein then the treatment works from one, but preferably from both, outer sides of the laundry item against the pressure plate with treatment brushes.
