Definitions
- the invention relates to a method for generating an ion current in a hair styling or care device having an ionization device with at least one high voltage generator and at least one electrode connected to the high voltage generator.
- Hair care appliances of the aforementioned type are, for example, hair dryers, air curlers, straighteners, crimpers or the like.
- an ionization device With such an ionization device, an ion current should be supplied to the hair to be nourished during the care or shaping process. This serves the purpose of neutralizing electrostatically charged hair, typically by combing it, with respect to its charge.
- Such an ionization device has a high-voltage generator and one or more electrodes connected to it. The electrodes are designed to be suitable for generating an ion current.
- an ion current with negatively charged TeN chen (anions) or positively charged particles (cations) is generated.
- the ionization devices in previously known hair styling or care appliances can be operated with a single polarity. Since, according to experience, hair to be cared for typically typically positively charges electrostatically, the ionization devices are designed to generate an anion current. Hair dryers have also become known which have two ionizing devices in order to be able to generate an ion current of positively or negatively charged particles depending on the actual polarity of the electrostatic charge of the hair to be nourished or shaped.
- Such a hair styling device is described in WO 03/101242 A2.
- the electrodes used for the generation of the ion current typically sit in hair dryers within the air outlet opening.
- the air stream serves at the same time as a transport medium for transporting the generated ions to the hair.
- the invention is therefore the object of developing an aforementioned hair styling or care device such that an ion supply to the hair to be cared for or formed is improved especially in those hair shape or care devices that do not have a have an airflow generating fan.
- This object is achieved according to the invention by a generic method mentioned at the outset in which an ionic current with a first polarity of its ions takes place during the ionization process for supplying ions to the hair to be nourished or formed and in which this ionic current is intermittently interrupted and interrupted the time of interruption an ion current with ions of a second polarity opposite to the first polarity is generated.
- an ion generation in principle takes place in a first polarity, so that, for example, negatively charged particles and thus anions are supplied to the hair to be nourished or shaped. Periodically, this ion current or its generation is interrupted.
- an ion current is generated with ions of a second polarity, thus for example cations.
- the generation of the ionic current with ions of the other, opposite polarity is used in this method not primarily for the purpose of supplying the hair to be cared for or formed an ion current of a second polarity, but the purpose of the closer environment of a housing part with respect to the electron-emitting tip the ionization electrode, so for example to neutralize the electrode holder. For this reason, it is sufficient if the ion current of the second polarity is generated only for a short period of time.
- the period of the ion current for generating ions of the first polarity is typically several times longer than the time period provided for the generation of the ion current with the ions of the second polarity.
- the polarity of the high voltage generator is switched from the first polarity to the second polarity for this purpose.
- FIG. 1 shows a schematic representation of an ionization electrode of an ionization device of a hair styling device received in an electrode holder immediately after the ionization device has been put into operation
- FIG. 2 shows the representation of FIG. 1 with the ions generated by the ionization electrode after a certain period of time of the operation of the ionization device
- FIG 3 shows the arrangement of Figure 2 after generating ions of opposite polarity and 4a
- 4b a diagram showing the time course of periods for generating ions of one polarity and the other polarity with the ionization device of Figures 1 to 3 ( Figure 4a) and a schematic representation of the intensity of the intensity of an operation the ionization device according to Figure 4a adjusting ion current ( Figure 4b).
- An otherwise not shown hair styling device for example, a so-called Straightener for straightening hair, has in the area adjacent to his hair-styling via an inserted into his housing 1 electrode holder 2.
- an ionization electrode 3 is arranged in the electrode holder 2 in the electrode holder 2 in the electrode holder 2 .
- the ionization electrode 3 is electrically connected to a high voltage generator 4.
- the high voltage generator 4 serves to apply high voltage to the electrode 3, for example 5 kV.
- the ionization electrode 3 is formed as a needle electrode in the illustrated embodiment.
- the high voltage generator 4 is in turn connected in a manner not shown to a voltage source.
- the high-voltage generator 4 is controlled by a microprocessor 6.
- the hair styling device has a push-button, not shown in the figures, with which an operation of the generally designated by the reference numeral 7 lonticians owned comprising the high voltage generator 4, the microprocessor 6 and the ionization electrode 3 can be switched on and off.
- the ionization device 7 is designed so that an ionic current with anions is generated by the ionization electrode 3.
- Figure 1 shows schematically the operation of the ionization device 7 immediately after switching on the same. The resulting ionization current is indicated by the anions shown diagrammatically.
- the tip 5 of the electrode 3 is seated for safety reasons, so that a touch by a user of the Hair styling device is avoided, within the electrode holder 2, thus set back from the mouth of the same.
- an increasing number of anions 8 accumulate in the mouth region of the electrode holder 2, with the consequence that with increased accumulation of anions in the mouth region of the electrode holder 2 the ion current directed to the hair to be formed is weakened becomes less effective.
- the ionization device 7 at intervals - ie intermittently - during the generation of an ionic current containing the above-described anions, it is briefly interrupted to produce an ion current or due to its short-term ion bombardment with ions of opposite polarity and thus in the present embodiment to produce with cations. For this purpose, the polarity of the high voltage generator 4 is switched.
- the relevant control of the high voltage generator 4 is taken over by the microprocessor 6.
- the anions accumulated in the mouth region of the electrode holder 2 are neutralized.
- the polarity of the high voltage generator 4 is switched again, in order subsequently to be able to generate an anion ion current again over a further period. This process is repeated as long as the ionizing device 7 is operated.
- FIG. 4a schematically shows a section of the ion streams which change as a function of the ionization device 7 and change in polarity.
- the time is plotted on the x-axis in FIG. 4a.
- the diagram makes it clear that in the illustrated embodiment, the ion stream to be supplied to the hair to be nourished is that with negatively charged particles (anions).
- the anion stream to be supplied in principle to the hair to be formed is interrupted for a short time - in the illustrated embodiment at uniform time intervals - by cation impacts for neutralizing the electrode holder 2.
- FIG. 4b shows, in a schematic diagram, the changing information intensity of the anion current.
- the time is plotted on the x-axis and on the y-axis the intensity of the cation stream to be supplied to the hair to be formed.
- the ion current intensity is compared with the operation of a conventional ionization device (dot-dashed) with respect to the intensity profile when an ionization device is operated, as described above.
- an ionization device While in operation of an ionization device according to the prior art after a rapid construction and a first plateau phase adjusts a successive decrease in the intensity of the hair to be supplied to the hair to be treated ion current is in the subject of the inventive method in the cycle of Figure 4a shown cation bursts to neutralize the electrode socket 2, the ion current power drop repeatedly interrupted and raised again to the initial initial level. Therefore, with this method, an ionization device can be effectively supplied to the hair to be cared for or shaped even without an air flow transporting the ions. In particular, such an ionization device can in principle be operated at a lower power, it being ensured by the operation thereof that sufficient ion current is supplied to the hair to be cared for or shaped.
