Definitions

  • the invention relates to a method for controlling a plasma source of a device, in particular a handheld device, and such a device whose plasma source can be controlled using this method.
  • Plasmas have been used for some time because of their odor-inactivating and antimicrobial properties.
  • the causes of the antimicrobial effect of a plasma lie in the heat generated by the plasma, drying out, shear stress, UV radiation, free radicals and charges.
  • solid, liquid or gaseous, plasma is often referred to as the fourth state of aggregation.
  • low-pressure plasmas which are also referred to as cold plasmas and which are usually operated at room temperature.
  • cold plasmas have been used in medical technology for some time, including in the treatment of poorly healing wounds or wounds that do not heal, for example in so-called plasma pens, in which the antimicrobial effect of cold plasma is used.
  • odor components that can be cell components of a biological organism.
  • Substances that are particularly relevant to odors include butyric acid, sweat, settled cigarette smoke and others, i.e. generally odors that can be perceived as unpleasant.
  • non-odour-relevant molecules such as allergens, protein molecules, prions and the like can be eliminated or destroyed.
  • odor components which in the case of cell walls, bacteria, germs, viruses, fungi or other comparable microorganisms mainly consist of carbon compounds, are exposed directly 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 up to the point where the tensile strength is exceeded and the associated destruction of the odor molecules. Low-pressure plasmas are particularly well suited for inactivating odors on textile fabrics or on household surfaces or the like, since thermal damage to such a surface is not to be feared.
  • a hand-operated device is understood to be a mobile device that is moved manually by a user—that is, by means of one or both of his hands—during operation of the device over the surface to be treated.
  • a hand-held device In contrast to stationary devices, such a hand-held device is typically portable by the user, which means that the device must be matched in terms of mass and dimensions.
  • the plasma source of the respective device is typically controlled independently of the nature of the surface to be treated.
  • the electrical power output of the plasma source that is required for proper treatment of a textile surface depends on the mesh size of the textile surface such that a large mesh size requires less electrical power output than would be the case with a smaller mesh size. This can be explained by the fact that the reactive particles produced in the plasma can penetrate the material of the textile surface more easily with a larger mesh size than with a smaller mesh size.
  • the basic idea of the invention is therefore to adjust an electrical power output from a plasma source of a device for treating a textile surface, which is delivered to a plasma, to a condition of the surface to be treated. This means that the nature of the surface to be treated is taken into account when controlling the plasma source.
  • the electrical power output of the plasma source can advantageously be adjusted in such a way that particularly gentle treatment of such sensitive surfaces is made possible.
  • “gentle treatment” means a treatment of the textile surface that is particularly low-wear and has a particularly low color impact.
  • the electrical power output of the plasma source to the plasma can be reduced if it is recognized that the textile surface to be treated has a large mesh size, which reduces the electrical energy consumption of the device.
  • the electrical power output of the plasma source to the plasma can be increased if it is recognized that the textile surface to be treated has a small mesh size, which is necessary in order to treat the material of a textile surface with a small mesh size with the plasma with the desired result .
  • the plasma is generated during operation of the device using the plasma source of the device and is applied to the surface to be treated.
  • an electrical power output from the plasma source is adapted or tuned at least once to the plasma generated, depending on at least one property of the surface to be treated. This tuning is expediently carried out in the form of an adjustment or a variation of the electrical power output. In this way, an optimum compromise between gentle and at the same time effective treatment can always be advantageously achieved for a wide variety of surfaces to be treated.
  • the at least one adjustment of the power output expediently takes place while the device is being moved over the surface to be treated. In this way, the power output can be adapted to the changing nature of the surface.
  • a change in the power output therefore particularly preferably takes place when the nature of the surface changes, in particular when the device is moved across the surface.
  • the nature of the surface to be treated is specified by a user of the device.
  • the condition is expediently specified by the user of the device by means of an assignment to a predefined condition category.
  • the condition specified by the user for the method is supplied to the device via an input direction.
  • the input device is integrated in the device or part of a separate mobile device that is expediently wireless and coupled to the device for data transmission.
  • the electrical power output is preferably tuned incrementally during operation of the device. Power output is particularly preferred matched exactly once. This offers a particularly easy-to-implement possibility of implementing the tuning of the electrical power output of the plasma source to the plasma.
  • the nature of the surface to be treated is detected by means of a sensor device scanning the surface, in particular when the device is moved across the surface to be treated.
  • the sensor device is preferably integrated in the device or part of a separate mobile device which is coupled to the device in a data-transmitting manner, preferably wirelessly.
  • the electrical power output is preferably tuned continuously during operation of the device. In this way, a particularly precise adjustment of the electrical power output from the plasma source to the plasma can advantageously be implemented.
  • both the device and the separate mobile device can each have both an input device and a sensor device.
  • the electrical power output can then be adjusted either instrumentally or continuously during operation of the device. This offers a particularly flexible possibility of tuning the electrical power output of the plasma source to the plasma.
  • the sensor device comprises a photo sensor and alternatively or additionally a camera, an ultrasonic sensor or a mechanical scanning element.
  • a sensor device allows a particularly precise and, at the same time, rapid detection of the nature of the surface to be treated.
  • the at least one quality of the surface to be treated is expedient, a color and alternatively or additionally a mesh size or a type of textile. Such properties of the surface to be treated are particularly easy to identify.
  • the invention also relates to a device for treating a textile surface by means of a plasma.
  • the device is hand-guided, so it can be done manually by one users are guided.
  • the plasma is preferably a cold plasma.
  • the device includes a plasma source for generating and emitting the plasma.
  • the plasma source is designed in such a way that an electrical power output can be adapted or varied to the plasma generated.
  • the device also includes a control/regulation device that is set up/programmed to carry out a method according to the invention as described above. The advantages of the method according to the invention presented above are therefore also transferred to the device according to the invention.
  • the method according to the invention is particularly preferably carried out during operation of the device according to the invention.
  • the device has a data interface with a transmitter and a receiver.
  • the data interface serves to transmit data, in particular wirelessly.
  • the data interface can be based on the Bluetooth or WiFi standard.
  • the device can be coupled to a separate mobile device by means of this interface. This means that the computing capacity of the mobile device can advantageously be used in order to carry out the method according to the invention, with which the computing capacity implemented in the device can be reduced as a result.
  • a sensor device for scanning the surface to be treated is integrated in the device, by means of which sensor device at least one condition of the surface to be treated can be identified. This allows the electrical power output of the plasma source to be continuously adjusted, which proves to be particularly advantageous when the surface to be treated has a plurality of sections with different properties.
  • the device includes an input device, by means of which at least one condition specified by the user of the device can be supplied to the device for controlling the plasma source. This allows a particularly intuitive control of the plasma source and, in order to reduce costs, the typically expensive sensors of the device can be at least partially dispensed with.
  • the invention relates to an arrangement which comprises a device according to the invention corresponding to the above description and a separate mobile device.
  • the arrangement with the device and the mobile device can be an arrangement with the device and the mobile device.
  • the mobile device is coupled to the device in a data-transmitting manner, preferably wirelessly.
  • the mobile device has an input device, by means of which at least one property identified by the user of the arrangement can be supplied to the device for controlling the plasma source.
  • the mobile device has a sensor device for scanning the surface to be treated, by means of which the nature of the surface to be treated can be identified. This allows the user of the arrangement to operate the device or the arrangement in a particularly convenient manner when treating the textile surface.
