Definitions

  • the invention relates to a battery-operated hair dryer.
  • the notion hair dryer is not limited to devices that just dry hair, like a blow dryer.
  • a hair dryer can also be used to style hair, and may take the form of a brush or curler blowing warm air, and may alternatively be called an air styler.
  • US 2018/0233788 discloses a battery-powered blow dryer configured to simultaneously cool the batteries and improve hair dryer performance. All batteries have a level of internal electrical resistance/impedance, which generates heat during both charging and discharging. Thus, using batteries to power a heating element and fan also generates heat within the batteries, battery packs, or internal circuitry as they discharge. This heat can shorten the life of the batteries, and may affect the discharge rate or run time of the batteries. Thus, a battery-operated blow dryer is disclosed that is capable of cooling to batteries and related circuitry to increase their performance, avoid overheating and safety issues, and/or extend the life of the batteries.
  • the handle may include a handle air flow channel in communication with a case air flow channel, so that air flowing through the handle exits into the case air flow channel.
  • the batteries may be positioned within the channel with gaps being formed between the handle and batteries that allow air flow around the batteries.
  • the handle may include one or more intake vents that allows in air to flow up the channel in the handle over the batteries and gaps between the individual cells.
  • the fan draws air that flows around the battery cells, then continues through the case and is blown over the heating element. While the air flow is cooling the batteries, the air flow is also being warmed, and the battery-warmed air flows to the heating element and is not wasted.
  • EP2255692 discloses a device for drying hair, comprising a hand-held unit to emit or discharge a flow of air to be directed onto the hair.
  • the hand-held unit has a power source which is arranged in a path of the air flow emitted or discharged from the unit. In this way, heat energy which is generated in the power source can be transferred directly to the air flow in the device.
  • a battery-operated hair dryer comprising a battery, and a fan propelled by a motor that is powered by the battery, and that has static air flow-shaping vanes that serve to cool the battery that is mounted adjacent to the fan.
  • the battery is positioned adjacent to (e.g. shaped around) a motor mount of the motor of the fan.
  • the battery is at least partly positioned in a handle of the battery-operated hair dryer, the fan being positioned adjacent to the handle.
  • Embodiments are based on the following considerations.
  • weight and weight distribution are very important.
  • Embodiments of the invention use the static airflow-shaping vanes at the outlet side of the hair dryer fan inside the hair dryer, as a heat sink for the batteries of a hair dryer. This results in minimizing components (as a single component will act both as a static airflow-shaping vane and as heat sink), and putting the battery close to the fan also results in a good weight distribution (as the fan is nicely in the middle of the hair dryer).
  • the static airflow-shaping vanes at the outlet of the fan are also handling all air from the fan, so that cooling efficiency will be optimal.
  • Using the static airflow-shaping vanes as battery cooling bodies, and thus mounting the battery close to the fan results in that the weight distribution is optimal, and in that there is less need for cooling channels to cool the batteries, which cooling channels may cause noise.
  • FIGs. 1 and 2 schematically illustrate a battery-operated hair dryer having a dryer housing DH.
  • a main air flow AF1 flows rather straightforward from an air inlet grill AIG to an air outlet grill AOG.
  • the air flow is caused by a fan F propelled by a motor M that is fitted in a motor mount MM.
  • air from the fan F is heated by a heater H.
  • the heater H and the motor M are powered by a battery B around the fan F, motor M and motor mount MM.
  • the battery B being positioned (immediately) adjacent to (e.g.
  • the fan's static airflow-shaping vanes V act as cooling ribs to cool the battery B by means of the main air flow AF1.
  • the battery B has more volume at the bottom of the dryer housing DH than at the top of the dryer housing DH. If so, there may be an additional need for cooling the battery B at the bottom. To that end, it is possible to have a secondary air flow AF2 from the air inlet grill AIG to the air outlet grill AOG along the bottom of the dryer housing DH.
  • the dryer housing DH there is no need for the dryer housing DH to have a rectangular cross-section; it may e.g. be round.
  • the heater H may be in series with the motor M or parallel to the motor M.
  • the battery B may be shaped in such a way, that its weight distribution is optimal for a hand-held hair dryer.
  • the asymmetrical shape of the battery B shown in Fig. 2 is less favorable in the shown orientation of the dryer housing DH, but if the dryer housing DH is rotated in such a way that its left lower corner becomes the bottom (i.e.
  • the handle of the hair dryer would be mounted to what is shown to be the left lower corner of the dryer housing DH), such a battery shape may be very favorable to get a good weight distribution.
  • the battery may be partly or entirely placed in the handle, while the fan is positioned sufficiently adjacent to the battery so that the fan's static airflow-shaping vanes can still serve to cool the battery.
  • any reference signs placed between parentheses shall not be construed as limiting the claim.
  • the word “comprising” does not exclude the presence of elements or steps other than those listed in a claim.
  • the word "a” or “an” preceding an element does not exclude the presence of a plurality of such elements.
  • the invention may be implemented by means of hardware comprising several distinct elements. In the device claim enumerating several means, several of these means may be embodied by one and the same item of hardware. Measures recited in mutually different dependent claims may advantageously be used in combination.
