Definitions

  • the invention relates to a cleaning device with a cleaning room in which objects to be cleaned can be arranged, and with a water inflow with which water can be introduced into the cleaning room. Furthermore, the invention relates to a method for cleaning objects with water, in which a cleaning room is filled with the objects to be cleaned and in which water for cleaning the objects is introduced into the cleaning room.
  • a washing machine for example, has a cleaning room with a laundry drum in which the dirty laundry can be arranged. During the washing process, the laundry is then cleaned by repeatedly introducing heated water mixed with a detergent into the rotating laundry drum, so that dirt is removed from the laundry and removed by the water and the detergent.
  • the document EP 1469119 A1 discloses a cleaning device according to the preamble of claim 1 and a method for cleaning objects with water according to the preamble of claim 12.
  • a dishwasher also has a cleaning room in which dirty dishes can be arranged. During the cleaning process, the dishes are then cleaned by repeatedly introducing detergent-heated water into the cleaning room.
  • the cleaning effect of both the washing machine and the dishwasher depends, among other things, on the amount and composition of the detergent or dishwashing liquid, the duration of the cleaning process and the temperature of the water.
  • the detergent or dishwashing liquid By using the detergent or dishwashing liquid, heating the water and carrying out the cleaning process over a certain period, natural resources and energy are consumed.

  • the present invention is based on the object of providing a generic cleaning device and a generic method in which the cleaning effect can be improved. Furthermore, the present invention is based on the object of reducing the resource and / or energy consumption during cleaning.
  • a cleaning device with a cleaning room in which objects to be cleaned can be arranged, and with a water inflow with which water can be introduced into the cleaning space, at least partially solved according to the invention in that the cleaning device has a plasma source for generating a plasma and in that the plasma source is arranged such that this is via the water inflow into the cleaning space introducible water can be at least partially acted upon by the plasma, and that the plasma source is designed as a plasma nozzle for generating a plasma jet, the plasma nozzle having an inlet for a working gas and means for ionizing this working gas.

  • reactive substances can have a long service life in water, sometimes even up to two hours, without the undesirable premature degradation of the reactive substances by chemical reactions with the air, in particular with nitrogen. Therefore, the reactive substances in the water are available long enough to improve the cleaning effect when the water comes into contact with the objects to be cleaned.
  • the reactive substances can react with dirt particles on the objects to be cleaned and thus contribute to cleaning, bleaching or disinfecting the objects.
  • the amount of cleaning agent, the temperature of the water and / or the duration of the cleaning process can be reduced while the cleaning effect remains the same.

  • Examples of plasma sources are plasma sources in which the plasma is generated by capacitive or inductive coupling, by dielectric barrier discharge, by corona discharge or by arc discharge, in particular by direct current, low-frequency or high-frequency arc discharge.
  • the plasma source is arranged in such a way that the water that can be introduced into the cleaning space via the water inflow can be at least partially acted upon by the plasma.
  • the plasma source can be arranged in such a way that the water can be charged with the plasma before or after it is introduced into the cleaning room.
  • the plasma source can be arranged such that the water can be charged with plasma without the plasma source itself coming into contact with the water. The wear of the plasma source can be reduced in this way.
  • the plasma source can be arranged such that at least a part of the plasma source is in direct contact with the water during operation.

  • laundry items can be cleaned better or more economically.
  • the disinfectant effect of the reactive substances in the water also enables effective disinfection of the laundry items. This is particularly advantageous for medical laundry, such as service clothing from medical professions, laundry from hospitals or other medical or nursing facilities.
