Adischarge grille 132 is vertically installed at the rear end of the interior of thenozzle 130. - The
hair dryer 100 further comprises aheating assembly 140 that is installed at the interior of thedryer housing 110 and theintake cover 120. Theheating assembly 140 has anassembly body 142, adriving motor 144, and a blowingfan 148. Asupport frame 144 protrudes from the front side of theassembly body 142. Thedriving motor 146 is mounted on the interior of theassembly body 142, and a part of which is inserted into thesupport frame 144. A rotation shaft (not shown) projects out of the rear side of thedriving motor 146. The blowingfan 148 is forcibly inserted into the rotation shaft (not shown) of the driving motor (146) so that the blowingfan 148 blows an outside air out of theinlet port 112 to theoutlet port 114 by the rotation of thedriving motor 146. - Further, the
hair dryer 100 includes anelectrical cord 150, anelectrical switch 152, and aheating wire 154. Theelectrical cord 150 supplies an electrical power to the drivingmotor 146. Theelectrical switch 152 is connected to theelectrical cord 150, which controls the opening and closing of the electrical power. Theheating wire 154 winds around thesupport frame 144 for heating a sucked air through theinlet port 112 of thedryer housing 110. - In the conventional hair dryer structured as above, when the
hair dryer 100 is operated by turning on theelectrical switch 152, the electrical power from the electrical power supplying part (not shown) is supplied to thedriving motor 146 and theheating wire 154 through theelectrical cord 150. The driving motor (146) is rotated in a predetermined speed of revolution, and the heating wire (154) generates a heat to a predetermined temperature. - In this state, the user turns the
nozzle 130 of thedryer housing 110 toward his head and dries and styles the hair by blowing warm or cool air. - The
heating wire 154 and thedriving motor 146 of theheating assembly 140 generate an electromagnetic field by supplying the electrical power. Theheating wire 154 and thedriving motor 146 are composed of a magnet, an armature coil and a rotator coil. Thus, an electromagnetic wave, which is composed of an electronic field and a magnetic field, is generated by the electromagnetic field. The electromagnetic wave accordingly kills the living cells or damages the hair by upsetting the nerve system. Moreover, it causes problems for human beings such as headache, dermatitis and chronic fatigue. Furthermore, a conductive material easily shields the electronic field of the electromagnetic wave but easily fails to shield the electronic field. Thus, there is the problem that the electronic field is directly transmitted to the body of the user. - The present invention solves the foregoing problems. It is an object of the present invention to provide the hair dryer that prevents transmitting of the magnetic wave to the user of the hair dryer by installing the shielding member in the interior of the dryer housing.

motor 246 is rotated in a predetermined speed of revolution by the supplied electrical power. Simultaneously, theheating wire 254 generates a heat to a predetermined temperature by the supplied electrical power. Generally, the speed of revolution of the drivingmotor 246 and the temperature of the heat of theheating wire 254 have the high function, the medium function and low function. The functions are controlled by the demands of the user. Additionally, thehair dryer 100 can select cool air instead of the heat of theheating wire 254. - At this state, the driving
motor 246 rotates the blowingfan 248 so that an outer air is sucked into the interior of thedryer housing 210 of thehair dryer 200 through theair inlet 222 of theintake cover 220. After theheating wire 254 heats the sucked air, it is passed through theoutlet port 214 of thedryer housing 210, thenozzle 230, and thedischarge grille 232. Thus, the sucked air is blown toward the outside of thedryer housing 210. - Therefore, the
hair dryer 200 can be used to dry and style the user's hair by selectively blowing warm or cool air. - In this process, during the heating process of the
heating wire 254, the magnetic wave is generated around theheating wire 254 by supplying the electrical power. At this time, the shieldingmember 270, which is mounted on thesupport frame 244 for wrapping the outer surface of theheating wire 254, absorbs and shields the magnetic wave from theheating wire 254 not to pass through thedryer housing 210. - FIG. 2 is a view showing an installed state of a shielding
