Definitions

  • the invention relates to a hair dryer.
  • Prior art hair dryers generally comprise a housing, an air inlet allowing air to enter the housing, a fan to move the air from the air inlet via a heater to an air outlet where heated air leaves the housing.
  • the invention provides a hair dryer for generating an air flow, the hair dryer comprising a curved shape unit defining an outer surface of the hair dryer, a first part of the outer surface being at an angle to a desired direction of the air flow, and a second part of the outer surface being aligned with the desired direction of the air flow; a fan unit at the first part of the outer surface, the fan unit having an air inlet, and an air outlet arranged for blowing air along the first part of the outer surface; and a heater arranged for heating a user's hair.
  • the heater may be at least partially integrated in the fan unit, to heat the airflow to indirectly heat the user's hair. Additionally or alternatively, the heater may comprise a heating wire embedded in the outer surface, e.g. mounted in a groove of the outer surface, to heat the airflow to indirectly heat the user's hair. Additionally or alternatively, the heater may comprise an infrared radiation unit inside the curved shape unit arranged for producing heat radiation towards the user's hair, to directly heat the user's hair.
  • a motor of the fan unit may be mounted at an inner surface of the curved shape unit.
  • the hair dryer may comprise a handle coupled to the curved shape unit, the handle having a grip part arranged for being gripped by a user, and a connection part between the grip part and the outer surface, the connection part being thinner than the grip part.
  • the Coand effect may also result in that ambient air not outputted by the fan unit is made to flow along with the air flow from the fan unit, thereby resulting in a total air flow that has more impact than just the air flow generated by the fan unit.
  • the Coand effect has been explained in https://en.wikipedia.org/wiki/Coand%C4%83_effect.
  • Figs. 1A, 1B , and 2 show first and second embodiments of a hair dryer according to the invention.
  • Figs. 1A, 1B show a side view and a rear view, respectively, of a first embodiment of a hair dryer according to the invention.
  • the hair dryer comprises a curved shape unit CS defining an outer surface of the hair dryer.
  • a first part OS1 of the outer surface is at an angle to a desired direction of the air flow AF, and a second part OS2 of the outer surface is aligned with the desired direction of the air flow AF.
  • a fan unit F is mounted at the first part OS1 of the outer surface.
  • the fan unit F has an air inlet with an air inlet grill AIG, and an air outlet with an air outlet grill AOG. The fan unit F blows air from the air outlet AOG along the first part OS1 of the outer surface.
  • a motor M of the fan unit F may be mounted at the inner surface of the curved shape unit CS, in the position shown in Fig. 1A .
  • the motor M may be at the right-hand side, in the center of the fan F, e.g. in the center of the air inlet.
  • the hair dryer of Fig. 1 further comprises a heater for heating a user's hair.
  • the heater may be located at the outer surface of the curved shape unit.
  • the heater may be at least partially integrated in the fan unit F, i.e. behind the air inlet grill AIG or before the air outlet grill AOG.
  • the heater comprises a heating wire HW embedded in the outer surface, e.g. mounted in a groove G of the outer surface OS1, OS2, thereby preventing a user from directly touching the heating wire HW.
  • the groove G is preferably provided with a covering layer, to even better prevent the user from directly touching the heating wire HW
  • the heater comprises an infrared radiation unit inside the curved shape unit CS.
  • the infrared radiation unit is arranged for producing heat radiation towards the user's hair.
  • inside means at the left end in the side view of Fig. 1A , where in Fig. 1A the motor M is positioned.
  • the inside of the curved shape unit CS is preferably reflective, so that all heat radiation is eventually radiated to the left, in parallel with the air flow AF. Any temperature increase of the curved shape unit CS as a result of the heat radiation will be counteracted by the air flow AF flowing along the outer surface OS1, OS2, resulting in a desired increase of the air flow temperature.
  • a handle H may be coupled to the curved shape unit CS.
  • the handle H has a grip part GP arranged for being gripped by a user, and a connection part CP between the grip part GP and the outer surface OS 1, OS2, the connection part CP being thinner than the grip part GP.
  • the connection part CP being thinner than the grip part GP.
  • Fig. 2 shows a second embodiment of a hair dryer according to the invention.
  • the curved shape unit CS is not symmetrical, and a main unit MU comprises the fan unit, the motor of the fan unit, and the heater.
  • the main unit MU is arranged to blow heated air along the first part OS1 of the outer surface.
  • the main unit MU also functions as the handle.
  • the motor of the fan unit is at the same side of the curved shape unit CS as the air propelling part of the fan unit.
