As shown in FIG. 4,

openings

1111 and 1121 are formed in the

inner surfaces

1113 and 1123 of the pair of

injection members

1110 and 1120. The

openings

1111 and 1121 are formed to be inclined with respect to the

inner surfaces

1113 and 1123 of the

injection members

1110 and 1120. The injection direction of the compressed air is also formed to form a specific angle. Compressed air injected from the pair of

injection members

1110 and 1120 crosses at an angle. In other words, while blowing the air under a strong pressure to the hair to shake off the hair. The present invention dries the hair and simultaneously dries the hair under high pressure air.

Specifically, as shown in Figure 5, the intersection of the compressed air is injected when the hair is accommodated between the two injection members (1110, 1120) of the hair dryer (1000) of the present invention and the hair dryer (1000) moves downward As you move downward, you can moisten your hair more effectively. The tip of the

injection members

1110 and 1120 may be inclined to narrow the width of the

injection members

1110 and 1120 toward the tip. Accordingly, the width of the inlet of the injection unit 1100 is widened, so that the hair can be inserted more easily.

In the present embodiment, the

injection members

1110 and 1120 are formed as a pair, but the configuration is not limited thereto, and the compressed air does not cross, and the compressed air is injected only in one direction by one injection member. It may be formed.

openings

1111 and 1121 may be one of a circle, an ellipse, a square, a rectangle, a triangle, and a slit. The distance between the

openings

1111 and 1121 may vary according to the shapes of the

openings

1111 and 1121. Slit-shaped openings (FIG. 6F) may be formed integrally instead of a plurality of openings. In this case, a rich supply of compressed air can dry your hair faster. Although the shape of the

openings

1111 and 1121 has been described as being circular, elliptical, square, triangular, and slit-like, the

openings

1111 and 1121 may be formed in various shapes.

Meanwhile, in the present embodiment, the openings are formed in the same shape with respect to the two injection members, but may be formed in different shapes. For example, a circular opening is formed in one injection member and a rectangular opening is formed in another injection member. Since the cross sections of the openings are different in the respective injection members, the pressures at which the compressed air is injected are different from each other. From this, the injection pressure is different in the hair accommodated between the two injection members, causing the hair to swing.

In another embodiment, the inclination of the openings may be varied so that the injected compressed air faces different heights of the hair, causing the hair to swing.

As shown in FIGS. 7A and 7B, a tapered protrusion 1130 may be formed at inner ends of the

injection members

1110 and 1120. The protrusion 1130 is formed on an inner side surface of the two

injection members

1110 and 1120 facing each other. The protrusion 1130 prevents the hair from escaping to the outside when the hair is accommodated in the space between the two

injection members

1110 and 1120. Since the hair dryer 1000 of the present invention can be ejected to the outside of the injection unit 1100 without being fixed because the high pressure wind is injected, the protrusions 1130 at the tip of the

injection members

1110 and 1120. To prevent the departure of hair.

The protrusion 1130 is formed in a tapered shape toward the outside of the injection member 1110. An opening 1131 may be formed on the tapered surface of the protrusion 1130 to inject compressed air. The present invention prevents the detachment of the hair even by the protrusion 1130, but in addition, the compressed air is injected into the spray unit 1100 through the opening 1131 formed in the protrusion 1130, thereby further preventing the detachment of the hair. have. The protrusion 1130 may be formed in a shape in which both sides thereof are inclined toward the center of the protrusion 1130. In another embodiment, the tip of the

injection members

1110 and 1120 may be formed in a hook shape instead of the separate protrusion 1130 to serve as the protrusion.

As shown in FIG. 8, the compressed air providing unit 1300 includes a vacuum motor 1310, a noise reflecting unit 1320, and a sound absorbing unit 1330. The vacuum motor 1310 sucks and provides external air. Air is sucked in through the slit formed in the casing of the vacuum motor 1310. At this time, the hair can be sucked along the flow of the air sucked, it may be provided with the first and second air intake filter (1313, 1315). The first air intake filter 1313 is coupled to the upper portion of the noise reflector 1320. The second air intake filter 1315 is formed at the outer periphery of the casing of the compressed air providing unit 1300. The first and second

air intake filters

1313 and 1315 are formed in the casing of the compressed air providing unit 1300 to prevent the hair from being sucked in by the suction force of the vacuum motor 1130. Meanwhile, the compressed air in the vacuum motor 1310 is designed to store and maintain a constant pressure inside the support 1200 and inside the

injection members

1110 and 1120.

As the fan (not shown) of the vacuum motor 1310 rotates, noise is generated. The noise reflector 1320 reflects the noise generated by the vacuum motor. The noise reflector 1320 is positioned adjacent to the vacuum motor 1310. The noise reflecting unit 1320 is formed in a dome shape. The noise reflector 1320 reflects the noise generated by the vacuum motor 1310 in the dome shape. The noise reflector 1320 reflects the noise in various directions. Noise that changes in phase as it is reflected cancels out and interferes with noise directed to the noise reflector. Noise generated when the vacuum motor 1310 operates is primarily reduced by canceling each other inside the noise reflector 1320.

The sound absorbing unit 1330 is positioned adjacent to the noise reflecting unit 1320. The sound absorbing portion 1330 is formed of a sound absorbing material. As the sound absorbing material, a porous material or the like can be used. The sound absorbing unit 1330 may be formed by applying a single or double plate-like structure using a porous material such as rock wool, glass wool, tex, or sponge. The sound absorbing unit 1330 absorbs the reached noise to prevent the sound from coming out of the compressed air providing unit 1300. According to the present invention, the noise reflecting unit 1320 and the sound absorbing unit 1330 can significantly reduce noise generated by a vacuum motor.
