HAIR DRYER
First Claim
1. A hair dryer comprising:
- a housing defining an inner space therein, the housing having an inflow slot, through which external air is introduced into the inner space, in an outer surface of a side thereof;
an air current generation part disposed within the inner space of the housing to allow the external air introduced through the inflow slot from the outside of the housing to pass through the housing;
a heater disposed within the inner space to selectively supply heat into the air passing through the housing; and
a discharge nozzle coupled to one end of the housing, the discharge nozzle having a coanda surface on which the air passing through the inside of the housing passes to suction the external air by the air passing on the coanda surface, thereby discharging the mixed air together.

Abstract
A hair dryer includes a motor and a fan to generate an air current within a housing, and a heater for selectively supplying heat into air introduced from the outside of the housing by the fan. A discharge nozzle is disposed on one end of the housing. A coanda surface is disposed on the discharge nozzle. Thus, the air passing through the housing flows along the coanda surface to suction air outside the discharge nozzle into a central passage part of the discharge nozzle, thereby mixing the suctioned air with the air passing through the housing. The air mixed within the central passage part is discharged through a discharge hole of the discharge nozzle. Since the air passing on the coanda surface suctions the air outside the discharge nozzle, the motor may be reduced in capacity. Also, an electromagnetic shielding effect may be significantly improved.

10. A hair dryer comprising:
-
a housing defining an inner space therein, the housing having an inflow slot, through which external air is introduced into the inner space, in an outer surface of a side thereof; a motor disposed within the inner space of the housing, the motor rotating a fan for generating an air current so that air is introduced from the outside of the housing through the inflow slot to pass through the housing; a heater disposed within the inner space to selectively supply heat into the air passing through the housing; and a discharge nozzle coupled to one end of the housing, the discharge nozzle having an inner passage through which the passing through the inside of the housing passes and a coanda surface for guiding the air discharged from the inner passage to suction the external air by the air passing on the coanda surface, thereby discharging the mixed air together. - View Dependent Claims (11, 12, 13)
