Definitions

  • the invention relates to a hair care device having an ion generator.
  • WO 2015/196194 discloses a hair styling apparatus having an ion generator adapted to direct a concentration of ions to the length of hair.
  • the ionic discharge will impart a sleeker, smoother texture to the hair and reduces static electricity and frizz.
  • the apparatus may be provided with a control means that allows a user to selectively activate or de-activate the ion generator so that it may or may not be used during operation of the apparatus. Intermittent use is also contemplated. This may be achieved, for example, by an actuator or button and appropriate logic or circuitry.
  • Embodiments of the invention provide a hair care device, comprising an ion generator for providing ions to hair, and a switching circuit for switching on the ion generator later than a moment when the hair care device has been switched on.
  • the switching circuit may be coupled to receive an input from a sensor for measuring a moisture level of the hair, a sensor for measuring a temperature of the hair, and/or a timer for switching on the ion generator after a predetermined period has lapsed.
  • An advantage of the invention is that if the ion generator is only on when needed, its lifetime is longer. Or with the same lifetime, more economical components can be used.
  • the hair care device may be a hair dryer, a styling device such as a hot iron, an air styler, or a brush.
  • the invention is based on the recognition that it is not necessary to provide ions when the hair is still wet, as with wet hair no static electricity and frizz related problems occur anyway. It thus makes sense to only provide ions when the hair is relatively dry, which can be measured by means of a moisture measurement, and/or by a temperature measurement, or without any such measurement by simply only switching on the ion generator after some time has elapsed.
  • the moisture sensor may use any of the following techniques: resistance, reflection, surface tension, hair weight, friction, raman spectroscopy, back-reflected IR spectrum, and capacitance.
  • WO1999026512 discloses a hair dryer using remote sensing of the moisture content of the hair.
  • the temperature sensor may be an IR sensor. Infrared thermometers are known, see e.g. https://en.wikipedia.org/wiki/Infrared_thermometer. Hair dryers with a temperature sensor are commercially available, e.g. the Philips hair dryer HP8270, and are also disclosed in e.g. WO1999001726 . Using a the temperature sensor to determine dryness of hair could be based on the assumption that hair below 60 °C is too wet to suffer from static electricity and frizz related problems.
  • Alternative temperature sensors may use a thermocouple, a thin film type resistor, or an ultrasonic comb.
  • Using a timer is based on the realization that after e.g. 200 s of using a hair dryer, the hair has become sufficiently dry to become susceptible of static electricity and frizz related problems.
  • Fig. 1 shows an embodiment of a hair care device in accordance with the present invention, based on US 2015/0250690 but with the new elements of the present invention.
  • Hair care device 100 includes a power supply unit 200, a control device 300, a blower mechanism 400, ion generating device 500, and an operation/display unit 700.
  • Power supply unit 200 receives power from an external power supply 10 transmitted from a power connector 20, which is connected to a power receiving unit 205. Power supply unit 200 then distributes the received power, and supplies driving power to control device 300, blower mechanism 400, and ion generating device 500. Note that when hair care device 100 is operated with power from a power storage device (not shown) incorporated therein, power supply unit 200 distributes the power from the power storage device to control device 300, blower mechanism 400, and ion generating device 500.
  • Blower mechanism 400 includes a fan drive unit 410 and blower fan 420.
  • Fan drive unit 410 is a drive device for driving a fan motor (not shown) contained in blower fan 420.
  • Fan drive unit 410 drives blower fan 420 based on an instruction from control device 300.
  • Ion generating device 500 includes a generating element drive circuit 510 and ion generating element 520.
  • Generating element drive circuit 510 is a circuit for applying voltage to a high-voltage circuit contained in ion generating element 520, based on an instruction from control device 300.
  • Ion generating element 520 is formed along a path of air flow leading to ion discharge port 120 from blower fan 420. This causes ions generated by ion generating element 520 to be delivered to ion discharge port 120, and the ions are discharged out of hair care device 100 through ion discharge port 120.
  • ion generating device 500 may be configured to be separable from a housing of the hair care device.
  • Operation/display unit 700 is an interface for receiving an operation signal through the user's operation, and notifying the user of information.
  • Operation/display unit 700 is configured to include, for example, an operation instrument such as a switch and a display instrument such as an LED or a liquid crystal panel.
  • Operation/display unit 700 transmits the received operation signal from the user to control device 300, and displays notification information transmitted from control device 300 to the user.
  • Control device 300 controls blower mechanism 400, and ion generating device 500, based on the user's setting, operation, and the like.
  • control device 300 includes a timer (not shown) that ensures that the ion generating device 500 is only switched on after a period sufficiently long for the hair to be sufficiently dry to suffer from static electricity and frizz related problems. Preferably, this period is at least 100 s, and more preferably at least 200 s.
  • control device 300 has an input to receive information from a sensor S about the moisture level and/or temperature of the hair, so that based on that information, the ion generating device 500 is only switched once the hair has become sufficiently dry to suffer from static electricity and frizz related problems.
  • Fig. 2 illustrates a drying process of a temperature controlled hair dryer in accordance with the principles of the present invention, and the moment that ions can be switched on.
  • the left vertical axis shows hair mass M in mg as measured in a test environment, and the right vertical axis shows temperature T in °C.
  • the horizontal axis shows time in seconds.
  • hair mass M decreases as water evaporates, while the temperature T of the hair increases.
  • a first horizontal line at hair mass being about 4.2 mg indicates a starting position when hair is wet.
  • a second horizontal line at hair mass being about 2.7 mg indicates a subsequent situation when free water has sufficiently evaporated.
  • the ion generator can be switched on.
  • the moisture level of the hair would not be measured by determining its mass; the purpose of Fig. 2 is to visualize the relationship between temperature and moisture content of hair.
  • Fig. 2 illustrates that there are various ways to determine the moment when the ion generator can be switched on: by just waiting until the amount of time ⁇ T has passed, by measuring whether the hair temperature has reached a level of about 60 °C e.g. by using a device as disclosed in WO1999001726 , and/or by measuring a moisture level as e.g. disclosed in WO1999026512 .
