Benefits of technology

The present invention is about a hair dryer that uses a fan to increase the amount of air current and transfer it into the user's hair. The fan is rotated by a motor and the amount of air is increased through a process called "coanda effect." This results in a more efficient transfer of air current into the hair, making it faster and easier to dry. Additionally, the hair dryer is designed to prevent moisture from damaging the electrical components by placing them away from the air flow.

Problems solved by technology

Therefore, the electromagnetic waves may do harm to user's health.
As a result, the water may contact the heater to electrocute the user.

Embodiment Construction

[0029]Reference will now be made in detail to the preferred embodiments of the present invention, examples of which are illustrated in the accompanying drawings.

[0030]Referring to the drawings, a housing 10 defines a portion of an outer appearance of a hair dryer. In the current embodiment, the housing 10 has a cylindrical shape. Also, the housing 10 provides an inner space 11 in which parts to be described below are installed. The housing 10 may have a polygonal shape such as a square shape or an oval shape in cross-section.

[0031]A manipulation button 12 is disposed on a side of an outer surface of the housing 10. The manipulation button 12 manipulates an operation of the hair dryer. A plurality of inflow slots 14 is defined in a lower portion of the housing 10. The plurality of inflow slots 14 may be disposed side by side around a lower outer circumference of the housing 10. The inflow slots 14 may serve as passage through which air is introduced inward from the outside of the hou...

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.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The present invention relates to a hair dryer, and more particularly, to a hair dryer which generates an air current using a coanda effect.[0003]2. Description of the Related Art[0004]General hair dryers are devices in which an air current generated by a fan driven by a motor is discharged to the outside to dry or adjust user's hair. Air discharged from a hair dryer may be changed in temperature as occasion demands. Thus, to discharge air having a relatively high temperature, a heater may be provided within the hair dryer.[0005]However, in the hair dryer according to the related art, an amount of air discharged through a discharge hole is decided according to capacity of the motor and fan. Thus, to obtain a desired amount of air, each of the motor and fan should have capacity over a predetermined level. As a result, the hair dryer may be relatively increased in size.[0006]Also, when the motor is driven to rotate the fan...
