The silencer 130 has a sound absorbing space 132 formed in a hemispherical shape along the circumferential direction on the inner peripheral surface. In other words, the front and rear are opened so that the flow velocity of the air flowing into the front of the dryer body 110 is delayed so that the noise is reduced, A noise space is formed in a hemispherical shape along the circumferential direction and the sound level of the sound is controlled by the noise space 132. In addition to the air flow entering the rotation direction side of the fan M and the fan, The air flow is delayed to attenuate the noise.

The noise space 132 is a space in which the air introduced into the silencer 130 flows into the silencer 130 through the inner space of the silencer 130 and the inner circumferential surface of the silencer 130, The flow rate of the air flowing into the front of the dryer main body 110 is delayed compared to the flow rate of air flowing into the silencer 130. As a result, . However, the noise space 132 may be formed in a hemispheric shape, a circular shape, or a polygonal shape, and the inner peripheral surface of the silencer 130 may be formed in a dimple shape.

The silencer 130 may adjust the height of the sound generated by the silencer 130 and the silencer 132 depending on the size of the silencer 132.

That is, the silencer 130 is installed in the silencer 130 and the silencer space 132 so as to approximate the sound value of the noise generated by the rotation of the motor M and the fan or the wind blown into and discharged from the dryer main body 110, The noise generated in the silencer 130 and the noise space 132 may be amplified or reduced so that the rotation of the motor M and the fan or the flow of air into and out of the dryer body 110 The noise generated by the wind can be attenuated.

The acoustic member 120 is coupled to the rear of the silencer 130 and effectively reduces the noise of the hair dryer even at high wind speeds, thereby maximizing the drying efficiency and noise shielding of the hair dryer.

The acoustic member 120 is disposed at the rear end portion of the silencer 130 in a net shape having a plurality of through holes formed on both sides thereof so that the air introduced by the air blowing means 210 can pass through the acoustic member 120 It is possible to generate sound of a lower sound level than the noise generated by the rotation of the motor M and the fan or the wind that flows into and out of the dryer body 110 to rotate the motor M and the fan, The noise generated by the wind which flows in and out is firstly attenuated.

That is, the acoustic member 120 is preferably formed with a plurality of through holes, and the acoustic member 120 formed at a thickness of 1 mm is installed on both sides of the silencer 130 before and after the silencer 130 and flows through the blower means 210 The vibration noise generated when the air flows through the acoustic member 120 is reduced to generate a sound of a lower tone than the noise generated by the rotation of the motor M and the fan or the air flowing into and out of the dryer body 110 .

In other words, as the acoustic member 120 has a thickness of 1 mm, a plurality of through holes are formed, and the acoustic members 120 are installed transversely on both sides, the air passes through the acoustic member 120, The air that has passed through the acoustic member 120 collides with the inner air and the inner wall of the silencer 130 on the side of the noise space 130 and the flow rate of the air flowing toward the front side of the dryer body 110 is delayed, The noise generated by the rotation of the motor M and the fan or the wind that flows into and out of the dryer body 110 is secondarily attenuated to further maximize noise blocking and prevention.

In addition, since the silencer 130 and the acoustic member 120 of the present invention are selectively and detachably coupled to the rear of the dryer body 110, they can be partially replaced or repaired in case of failure, Can be saved, and is very economical.

According to the present invention, not only the noise generated when the hair dryer is used is minimized, but also the noise of the hair dryer is effectively damped even at the high wind speed to maximize the drying efficiency and noise shielding of the hair dryer, It is an invention that has the effect of attenuating noise.
