Definitions

  • the present invention relates to a hair dryer comprising a heater.
  • a conventional hair dryer is illustrated in Figure 1 and includes a body 1 containing a motor 5 for driving a fan 5a and a coil type heater 6 which is wound on a bracket 7. Air inlet ports 2 and a discharge port 3 are provided in the body to allow the flow of air therethrough.
  • a handle 4 extends from the body 1 on which a switch 8 for controlling the operation of the hair dryer is mounted and a lead through which electrical current may be supplied to the hair dryer extends from a lower end of the handle.
  • a plug (not shown) is attached to the free end of the lead 9 for insertion into an electrical supply socket.
  • the heater 6 radiates heat and the fan, driven by the motor 5, draws air into the body 1 through the inflow ports 2 toward the heater 6. The air blown toward the heater 6 is thereby heated and discharged through the discharge ports 3.
  • bracket 7 In addition to the aforementioned disadvantages, the bracket 7 must be quite large to accommodate the heater 6 which must be wound around the bracket many times to ensure its efficiency. This results in an increase in the overall size and weight of the hair dryer.
  • the wire forming the coil of the heater 6 may eventually break after continuous use due to the repetition of supply and interruption of electrical power.
  • a hair dryer according to the present invention is characterised in that the heater is formed from a ceramic material.
  • the ceramic material is silicon carbide (SiC), lanthanum chromate (LaCrO 3 ) or zirconium dioxide (ZrO 2 ).
  • the ceramic material may contain metal powder.
  • the hair dryer includes a body and an insulating member disposed between the heater and the body.
  • the hair dryer according to the present invention has a body 10, a motor 15, a fan 15a, a grip 14, a switch 18, and a cord 19, as does a conventional hair dryer of the type illustrated in Figure 1.
  • the heater 20 may also be manufactured with a compound material comprising a ceramic material and metal powder.
  • the heater 20 is disc shaped to conform with the shape of the body 10, and has a webbed construction.
  • the heater 20 is disposed so that air blown by the fan 15a is discharged through the discharge port 13 via the heater 20.
  • the heater 20 is surrounded by a member 23 which has a pair of connection terminals 26, each having a pair of holes 25a and 25b.
  • the hole 25a formed in the outer edge of the connection terminal 26 is used to fix the connection member 23 to the body 10 by means of screw, and the hole 25b formed in the inner edge of the connection terminal 26 is used to connect the connection terminal to the electrical cord 19.
  • the hair dryer has a control portion 30 for controlling the supply of electrical power from a power supply portion 29, a heat-radiating portion 40 for radiating heat, and a blowing portion 50 for blowing air toward the heater 20.
  • the control portion 30 comprises a filter 31 for reducing electrical noise, a fuse 33 for preventing the hair dryer form overloading and a user operated switch 18 for controlling the supply of electric power to the heater 20 and the motor 15.
  • the heat-radiating portion comprises a bimetal switch 41 and the heater 20.
  • the heater 20 radiates heat when the switch 19 is turned on, and the bimetal switch 41 prevents the heater 20 from overheating by disconnecting the supply of electrical power to the heater 20.
  • the blowing portion 50 comprises a voltage divider 51, a rectifier 53, and a motor 15.
  • the electrical power supplied from the power supply portion 29 is stepped down to an appropriate voltage and is then rectified into a direct current.
  • the voltage rectified from the rectifier 53 is applied to the motor 15, to drive fan 15a.
  • the heater 20 radiates heat and the fan 15a operates to into the body 10 through the inflow ports 12 and blow it toward the heater 20.
  • the heater 20 heats the air before it is discharged through the discharge port 13.
  • FIG. 5 A second embodiment is illustrated in Figures 5 and 6.
  • a pair of ribs 61 are provided within the body between which the connection member 23a fits.
  • a ring-shaped insulation member 60 is disposed between the ribs and insulates the heater 20 from the body 20 so that the heat generated from the heater 20 is not transferred to the body 20 through the connection member 23a which could otherwise cause deformation of the body 20.
  • the insulation member 60 is made of mica.
  • the heater 20 is disc shaped rather than having a webbed construction. It is formed with a plurality of holes 21 through which air blown by the fan 15a passes as it travels towards the discharge port 13.
  • the heater 20 of this embodiment is easier to manufacture than previously described embodiments.
  • a heater 20 is made of a heat-radiating ceramic material, it is no longer necessary to wind a coil of wire around on a bracket and so the manufacturing process is simplified. In addition, the ceramic heater is small and light in comparison with a coil type heater, so the weight and size of the hair dryer can be reduced.
  • the heater 20 can maintain continuous heat intensity, and overheating is prevented by the bimetal switch 41.
  • the ceramic heater 20 heats up much faster than conventional heaters.
