Definitions

  • the present invention relates to a plasma device for treating surfaces, in particular textiles, according to the preamble of claim 1.
  • the plasma device for inactivating preferably odor-relevant molecules and thus for refreshing surfaces, for example in textiles, is known.
  • the plasma device has a housing and an associated plasma source and at least one spacer, which ensures that a predefined distance is maintained between the plasma source and a surface to be treated, at which molecules attached to the surface to be treated pass through Electrons of the plasma can be inactivated.
  • a portable sterilization and disinfection device comprising: a housing, a power storage device arranged in the housing, and a transformer connected to the power storage device.
  • a high-voltage discharge device is connected to the transformer and configured to generate ozone and negative ions by high-voltage discharge under the boosting voltage output from the transformer.
  • plasma devices are used for this purpose, for example, by means of which bacteria, germs, viruses, spores, fungi and odor molecules in particular can be inactivated.
  • the disadvantage of the plasma device known from the prior art is that it only inactivates odor molecules, for example, or destroys cell walls of bacteria, microbes, etc., but no further cleaning of the surface takes place.
  • the present invention is therefore concerned with the problem of specifying an improved or at least an alternative embodiment for a plasma device of the generic type, by means of which a simple and at the same time improved cleaning of the surfaces to be treated is made possible.
  • the present invention is based on the general idea of attaching an additional cleaning device to a plasma device known per se, by means of which particularly fluff and hair can be picked up and a surface to be treated can thereby be better cleaned.
  • the plasma device according to the invention has a particularly elongated housing in which a plasma source is arranged. Running in the longitudinal direction of the housing is also a plateau surface with an electrode, preferably also running in the longitudinal direction, via which the plasma can be or is applied to the surface to be treated. The electrode can be surrounded by a ceramic substrate. The plasma is created directly on the surface of the plateau by igniting the electrode. In the transverse direction next to the electrode or the plasma source, i.e.
  • At least one contact element which during operation of the plasma device interacts mechanically with the surface to be treated, is provided according to the invention for the mechanical pretreatment of the surface .
  • the contact element can have a higher coefficient of friction on textiles than the plateau surface and acts in a similar way to a lint roller or thread lifter and allows lint or hair to be collected before the surface to be treated is impinged with plasma, resulting in a significant improved and at the same time simple surface treatment, for example cleaning, is made possible.
  • non-thermal plasma which is also referred to as cold plasma
  • Bacteria, spores, viruses, etc. can also be killed with such a plasma without a high temperature being necessary for this purpose.
  • the plasma is generated by applying electrical energy to a gas or gas mixture, as a result of which atoms of the gas are ionized, ie electrons are removed from an atomic shell, leaving a positively charged atom.
  • a gas consisting of a sufficiently high proportion of free ions and electrons is referred to as plasma.
  • the ions and electrons move as free charge carriers.
  • a cold plasma which can also be referred to as low-pressure plasma
  • reactive particles are formed, such as different oxygen and nitrogen species, which have a sufficiently long service life to damage organic compounds.
  • reactive particles such as different oxygen and nitrogen species, which have a sufficiently long service life to damage organic compounds.
  • These include atomic oxygen, superoxide radicals, ozone, hydroxyl radicals, nitrogen monoxide and nitrogen dioxide, which not only have a destructive effect on a wide variety of odor molecules, but also on cell components such as cell walls, and are therefore able to inactivate odors and cell walls of bacteria , germs, viruses, fungi or comparable microorganisms, since these, if they are directly exposed to the plasma, become negatively charged due to the bombardment with the electrons present in the plasma.
  • the plasma device according to the invention can thus be the odor-inactivating or cell wall-destroying effects of the plasma with the mechanical effects of the side of the electrode or the Combine plasma source arranged contact elements and thereby achieve a significantly improved treatment / cleaning of the surfaces to be treated.
  • the contact elements which are equipped in particular with the higher coefficient of friction, enable a textile to be treated to be tightened, which means that wrinkles can be smoothed out, for example, and the cleaning by the plasma can be additionally supported.
  • the contact elements are preferably arranged on both sides of the plasma source, so that a cleaning process combined with picking up hair or fluff can take place both in a forward and in a backward movement.
  • the contact elements By absorbing lint or hair, the contact elements also prevent lint or hair from penetrating into the plasma device, which can cause a deterioration in the cleaning effect of the plasma source in the long term. In addition, the contact elements can also protect a movement mechanism of the plasma source or the plateau surface from contamination and thus keep it functional in the long term.
  • the contact element has a surface area with a coefficient of friction that can be changed in the transverse direction of the plateau surface.
  • the coefficient of friction can increase away from the electrode, so that it also increases with increasing distance from the plateau surface.
  • a distance between the plateau area and the surface to be treated is preferably 0 mm in order to avoid excessive ozone development.
  • Ozone is a molecule (O 3 ) made up of three oxygen atoms (O).
  • O oxygen atom
  • direct contact with the textile surface must be ensured.
  • a low ozone concentration is also desirable because of ozone-induced respiratory irritation and discoloration. Due to the changing coefficient of friction on the surface areas and in particular Reliable tightening of the surfaces to be treated can also be achieved by an increase in the coefficient of friction as the distance from the electrode or the plasma source increases, as a result of which the cleaning effect can be improved.
  • the contact elements are arranged on curved side surfaces of the housing adjacent to the plateau surface and serve as wrinkle smoothers.
  • the increased coefficient of friction can be achieved, for example, by an appropriate coating, for example a coating made of rubber and/or silicone, but also by attaching bristles.
  • the position of the contact elements on the curved side faces can increase the effect of smoothing the textile to be treated.
  • the contact elements with an increased coefficient of friction can also extend further over the curved side surfaces on which the plasma device is usually gripped, thereby enabling reliable gripping.
  • the handling and guidance of the plasma device during the treatment process can also be simplified as a result.
  • the contact elements lie between the plateau surface and a curved side surface, so that the side surface on which the plasma device is usually gripped with thumb and finger remains free. This makes it possible to limit the contact elements, which means that on the one hand the smoothing or lint and/or hair-picking effect is obtained, but the coating of other surfaces can be avoided, which brings cost advantages.
  • At least one contact element is expediently designed as a thread lifter.
  • a thread lifter By means of such a thread lifter, not only can the surface to be treated be tightened, but it is also possible to pick up lint and/or hair, similar to a comb, which achieves an additional cleaning effect and in particular also prevents such lint or hair from penetrating into a Interior of the housing and thus an impairment, for example, an adjustment mechanism of the plasma source or the plateau surface can be avoided.
  • Thread lifters of this type can, for example, have raising elements, for example bristles that are inclined pointing the way from the plateau area.
  • Such thread lifters can also have straightening elements made of rubber, for example made of silicone, which can for example only be designed as knobs or the like, but at the same time allow fluff or hair to be collected and smoothed out.
  • the contact elements with the thread lifter are expediently arranged on a console, which is in particular formed in one piece with the housing, between the respective plateau surface and an associated curved side surface.
  • a console which is wedge-shaped in cross section, allows the arrangement of the contact elements with the increased coefficient of friction almost flush with the surface of the plateau area.
  • Such consoles also offer the possibility of providing corresponding recesses into which, for example, a contact element designed as a thread lifter or as a material strip with an increased coefficient of friction can be inserted. This in turn also enables the contact elements with an increased coefficient of friction to be replaced, for example in the event of corresponding wear. Due to the one-piece design of the console with the housing, these can be produced together with the housing as a cost-effective plastic injection molded part in a single step.
  • a UV light source is provided in addition to the plasma source, via which UV light can be applied to the surface to be treated.
  • a UV source it is possible to destroy DNA from microbes and thereby have an antibacterial or antimicrobial effect.
  • Such a UV source for emitting UV light can be activated simultaneously with the plasma source or in addition to or as an alternative to it, for example via a corresponding switch on the housing of the plasma device.
  • the plateau surface is expediently spring-loaded and protrudes beyond the housing of the plasma device when it is not in use.
  • Spring loading of the plateau surface or even the plasma source arranged in the housing makes it possible to guide the plateau surface close to the surface during the cleaning process, which in particular can prevent excessive ozone production by the plasma source.
  • the spring-loaded plateau surface causes also shielding the generated plasma from atmospheric oxygen, so that although sufficient oxygen is available for ozone production, the aforementioned excessive ozone production with the associated disadvantages does not take place.
  • a plasma device 1 for treating, in particular for refreshing, surfaces 2, such as textiles 3, an elongated housing 4.
  • surfaces 2 such as textiles 3, an elongated housing 4.
  • these textiles 3 can also have artificial fibers such as nylon.
  • surfaces or objects made of ceramic, plastic, feathers, leather, glass, wood or metal should also be able to be subsumed under the term "surface 2".
  • a plasma source 5 is arranged in the elongate housing 4 and is capable of generating plasma, preferably non-thermal plasma, which is also referred to as cold plasma, in a targeted manner for eliminating odors and certain hydrocarbons.
  • solid, liquid or gaseous, plasma is referred to as the fourth state of aggregation.
  • a sufficient amount of energy is supplied to a gas or gas mixture, for example in the form of electrical energy, some of the gas atoms are ionized, i. H. Electrons are removed from the atomic shell and move around as free particles, leaving a positively charged atom.
  • a gas consists of a sufficiently high proportion of free ions and electrons, the state of aggregation is referred to as plasma. So, plasma is matter whose constituents are partially charged components, ions and electrons that move as free charge carriers.
  • the causes of the antibacterial effect of a plasma lie in heat, dehydration, shear stress, UV radiation, free radicals and charges.
  • low-pressure plasmas which are also called cold plasmas
  • the heat plays a subordinate role, since these plasmas are operated at room temperature.
  • reactive particles are formed, such as various oxygen or nitrogen species, which have a sufficiently long lifetime to damage organic compounds in the event of indirect exposure.
  • These particles include including atomic oxygen, superoxide radicals, ozone, hydroxyl radicals, nitrogen monoxide and nitrogen dioxide. These particles show a destructive effect on a wide variety of odor components as well as cell components.
  • odor components which usually consist of carbon compounds, as well as the cell walls of bacteria, germs, viruses, fungi or other comparable microorganisms are directly exposed to the plasma, they become negatively charged due to the bombardment with the electrons present in the plasma. Due to the electrostatic repulsion, this leads to mechanical stresses that can even exceed the tensile strength and destroy the odor molecule or the cell wall. However, not only mechanical tension due to the charge can destroy the cell walls, but also the disturbance of the charge balance of the odor molecules or the cell wall through various other electrostatic interactions and electrolysis, e.g. B. by changing the permeability of the cell walls. A mechanism for inactivating microorganisms also results from the very high-energy ions.
  • the plasma can be generated by means of a high frequency. Low-pressure plasmas are therefore particularly well suited for inactivating odors on textile fabrics or on household surfaces or the like in order to achieve odor activation.
