Definitions

  • the invention relates to a method for wet treatment of laundry according to the preamble of claim 1. Furthermore, the invention relates to a device for wet treatment of laundry according to the preamble of claim 9.
  • the essential treatments are the wet treatment, such as the washing and optionally an aftertreatment, for example a finishing treatment, and the smoothing, especially mangling.
  • washing is done so far in washing machines with a rotating drivable drum.
  • a laundry item is moved with a rotating drum in a treatment liquid, and thereby washed, in particular prewashed and washed clear.
  • Aftertreatment such as, for example, equipping the laundry batch, takes place in a corresponding treatment liquid in the rotating drum.
  • the laundry items are optionally smoothed after prior dewatering and / or drying.
  • the smoothing is done mainly with a defect. Entering the laundry items in the defect or other smoothing done by a so-called input machine, the opposite corner regions of an edge of each garment on staples grips, spreads, and enters the defect or the like.
  • the document GB 648 609 discloses a method and apparatus for cleaning dirty laundry by exposure to ultrasonic waves.
  • this method several laundry items are simultaneously supplied to an ultrasonic bath in any condition. This treatment is neither very efficient nor gentle on the laundry.
  • the present invention seeks to provide a method and apparatus for simple, energy-saving and gentle treatment, especially wet treatment of laundry.
  • a method for achieving this object comprises the measures of claim 1. Accordingly, it is provided to enable the treatment liquid in a tank to vibrate. As a result, the laundry is washed by the otherwise stationary treatment liquid. Preferably, the laundry is washed by the only vibrated treatment liquid without a per se conventional division of the washing process in a prewash and a clear wash in a single operation, in particular finished washed.
  • the method provides that the items of laundry lying freely and completely immersed in the treatment liquid, individually suspended in the at least partially extended state at least one clip or held by at least one clip to be pulled through the vibrated treatment liquid.
  • the treatment liquid in at least one stationary basin or other container in vibration.
  • the still pool is not driven in rotation unlike the drum of known washing machines.
  • the pelvis does not change its position when treating the laundry items.
  • the pool can be installed stationary in the laundry and requires no movement drives. The thus resting pool thus requires no Energy to move it.
  • the treatment, in particular washing, of the laundry items takes place essentially only by vibrations of the treatment liquid.
  • the treatment liquid is preferably set in vibration by means of pressure waves, which in a preferred embodiment of the invention are sound waves, in particular ultrasonic waves.
  • the invention thus provides for ultrasonic washing of the laundry items.
  • other means may be provided to generate pressure waves in the basin, for example mechanical, electrical or hydraulic vibration and / or unbalance generators. Even by such means, pressure waves can be generated with relatively little energy and thereby put the treatment liquid in such vibrations that have an effective wet treatment, especially an effective washing, the laundry result.
  • a preferred development of the method provides for the laundry to be moved through the oscillating treatment liquid in at least a largely expanded state.
  • the laundry items are individually, without touching adjacent laundry items, moved through the vibrated treatment liquid, in particular continuously.
  • an effective washing of the laundry items can be done with the vibrated treatment liquid.
  • the laundry items do not touch or overlap each other, they are surrounded on all sides by the vibrated treatment liquid, which makes this type of wet treatment, especially the ultrasonic washing, particularly effective. Due to the vibrated treatment liquid, a movement takes place between the laundry and the treatment liquid.
  • a relative movement between the laundry and the treatment liquid is created by the preferably continuous pulling of the laundry through the treatment liquid. This enhances the effectiveness of the cleaning. Due to the above measures, only by the vibration in the treatment liquid with otherwise stationary treatment liquid, in particular stationary basin or container for holding the treatment liquid, an effective washing takes place, which is brought about or at least supported by the vibration in the treatment liquid and optionally the passage of the Washing through the treatment liquid.

  • a preferred development provides that the items of laundry are individually pulled with adjacent corner regions of an edge at least partially spread out by clamps held by the treatment liquid. As a result, the at least partially spread laundry items are fully accessible from the treatment liquid. Above all, however, the pieces of laundry which have been individually spread out on the brackets can be supplied by the same brackets to subsequent treatments. Each piece of laundry needs so only once before the laundry in the two opposite corner regions of an edge, in particular a leading edge, holding brackets to be entered. The individual items of laundry may then be supplied from the staples to a plurality of successive treatments without the need to transfer the individual items of laundry to other staples.
  • the garment can be supplied from these staples in the spread state of the defect or the like, without it previously on normally shortage arranged input machines for spreading the garment and other parentheses assigned to it must be passed.
  • it may be provided to increase the distance of the opposite corner regions of a leading edge of the laundry holding clamps for entering the laundry item in the defect or the like, so that the front edge of the laundry item when entering into the defect or the like is stretched more. This can be done without handing over the garment to other brackets by the distance between those brackets, which also transport the garment in particular by the wet treatment, is increased and so the garment in question is more spread.
  • brackets move it held each individual laundry item after washing through or over a drainage and / or drying section and only then enter the parentheses the individual laundry item in the shortage or the like. In this way, a clinging of the laundry items for different treatments avoided and the laundry items may also be transferred from the same brackets to the defect or the like as previously washed.
