The present invention relates to a blower pipe structure in which a hair dryer discharges wind in a swirling flow (hereinafter, referred to as a cyclone), such as a whirlwind. It relates to the construction of a cyclone blower dryer that discharges farther and faster.

Generally, a hair dryer is used to wind hair or dry hair, and such a conventional hair dryer is called a propeller or a fan (hereinafter referred to as a 'fan') on a shaft of an electrically operated motor. Since it is fixed, it generates a wind traveling in one direction by driving the motor, and a heating wire (heater) is provided in the middle of the wind discharge path for heating the discharged wind. When the user supplies electricity to dry the hair, the heating wire operates to heat up and the motor operates to rotate the fan so that the wind starts to be discharged, and the emitted wind is discharged as it is heated while passing through the heating wire.

In the conventional hair dryer having such a structure, the size of the driving motor and the fan is increased in order to satisfy the amount of wind discharged.

However, such a prior art has a problem such that the power consumption is increased because the size of the drive motor is increased, the size of the fan is increased, the noise is increased, and the appearance of the hair dryer is increased.

In addition, the discharged wind is not evenly mixed, the hot wind in some directions and the cold wind is discharged in the other direction is difficult to measure the temperature and at the same time hurt the hair and there is a problem that frequently occurs due to the temperature difference.

However, this conventional technology further includes a bearing 8, a snap ring 9, 9 ', a shaft 10, and the like in the discharge pipe to allow the wind to be discharged in a cyclone manner, which leads to a large number of components and complicated management. The cost is high, and the manufacturing time is increased, and at the same time, a lot of failures occur due to many driving divisions, such as shortening the lifespan.

In addition, such a conventional technique is that when the cyclone propeller 6 fails to rotate normally, the wind is not discharged normally and the heat generated from the heating wire is not cooled, so that the exhaust port 4 melts and the hair dryer 1 is damaged. There is a problem such as causing an image to the user.

Therefore, it reduces the number of components, shortens the production and manufacturing time, reduces the driving part by reducing the driving part, and extends the service life, while the combination of cold and warm air is well-blended to blow out the wind with a constant temperature.

Hair dryer (HAIR-DRYER) is for drying wet hair quickly or evenly reshaping hair. When operating power is supplied, the motor is driven and the fan fixed to the shaft of the motor rotates to generate and discharge wind. The discharged wind is discharged in a warmed state while passing through a heater that generates heat by supplying power. At this time, the wind may be well warmed or not warmed. The wind with the temperature difference is discharged in a straight state, and it is difficult to measure the temperature when the hair is dried or aligned using the hot wind with the temperature difference. Hurt. In addition, since the hairs located on the outside of the bundle of abundant hair are directly affected by the wind, and the hairs on the inside are not affected by the weak wind, it takes a long time to dry or remodel the hair. Increasing the wind speed and volume of wind reaches the hairs located inside. Therefore, the present invention is to change the structure without increasing the components in the blower structure of the hair dryer to make a cyclone-type swirl flow wind evenly mixed with well-heated wind and less warmed wind to make a constant temperature as a whole, to increase the wind speed discharged The present invention relates to a technique for providing a hair dryer structure.

4 is an assembly configuration diagram of a cyclone blower tube hair dryer according to one example of the present invention.

Hereinafter, with reference to the accompanying drawings, to supply or cut off the commercial power by the power cord 130 and the ON (OFF) control to receive the commercial power as the operating power through the plug (PLUG) The hair dryer 100 having the switch unit 120 includes a first blower tube 140, a second blower tube 150, a heater 160, a fan motor 170, and a lid 180. do.

The first blower tube 140 has a cylindrical shape having a taper shape larger than the diameter of the portion where the wind flows out, and a portion of the handle is further provided at the entrance portion where the wind flows, and the cylindrical portion has At least one selected from the protruding portion and the recessed groove portion projecting to the inner circumferential surface is a shape that is continuously connected in a spiral shape. In the accompanying drawings, for example, spiral projections and / or grooves are shown to be adjacent to each other. When the wind enters through the inlet by such a spiral groove or protrusion, it proceeds while rotating in a cyclone shape and discharged to the outlet. It is preferable to select the optimum value of the pitch (PITCH) value repeatedly configured for each depth and / or height and / or height of the spiral grooves or protrusions. In addition, the left turn and the right turn, which are the rotation directions of the spiral, apply a structure that rotates in any one direction by selection. The spiral grooves or protrusions may be continuously formed through the entire blower pipe, or may be discontinuously formed in a predetermined length or may be formed only once in a predetermined length. On the other hand, the first blower can be formed in one piece or two pieces by selection.

Cyclone (CYCLONE) is a strong rotation to generate a centrifugal force, when the wind is a strong rotation, there is a strong suction force, destructive force, straightness, etc. In general meteorology is a tropical cyclone typhoon. Adding rotational force to the wind emitted by the hair dryer sends it away at the same time, even with the same amount of wind. Therefore, when the wind discharged from the hair dryer to the cyclone wind is strong winds penetrate deeply even in the case of a large amount of hair. Therefore, the hot or cold air generated by cyclone wind in the hair dryer penetrates more strongly and deeply evenly, causing the hair to dry out and trim quickly.

Similar to the cylindrical structure of the first blower tube 140, the second blower tube 150 is a taper cylindrical structure having a larger diameter than the diameter of the discharged portion, the spiral groove or (and) The protrusions may be continuously connected in the same manner as the first blower tube 140, or a plurality of protrusions may be discontinuously connected, or only one of the protrusions may have a predetermined length. The pitch (PITCH) of the spiral groove or protrusion is applied in the same manner as the pitch value of the first blower tube 140, the depth or height may be the same or different, but the optimum value is selected by repeated experiments in the present invention It is preferable to form the same height.

The second blower tube 150 is made of an insulator that blocks heat transfer and withstands high heat, and may be made of one piece or two pieces in the same manner as the first blower tube 140.

The second blower pipe 150 converts and discharges the wind entering the inlet into the cyclone wind using spiral grooves and / or protrusions formed on the inner and outer circumferential surfaces, respectively.

That is, the wind flowing by the spiral grooves and protrusions formed on the inner circumferential surface of the first blower tube 140 and the outer circumferential face of the second blower tube 150 is converted into cyclone wind and discharged to the inner circumferential face of the second blower tube 150. Winds introduced by the formed spiral grooves and protrusions are converted into cyclone winds and discharged respectively.

At this time, the protruding portion of the spiral protrusion formed on the inner circumferential surface of the first blower tube 140 and the protruding portion of the spiral protrusion formed on the outer circumferential surface of the second blower tube 150 are fixed in close contact with each other. Therefore, the spirally formed large space enclosed by the recessed portion or the groove portion of the inner circumferential surface of the first blower tube 140 and the recessed portion or the groove portion of the outer circumferential surface of the second blower tube 150 is continuously discharged while rotating in a cyclone shape. do.

In addition, the spiral projections formed on the inner circumferential surface of the first blower tube 140 and the spiral grooves formed on the outer circumferential surface of the second blower tube 150 may be fixed in a state where the positions coincide with each other. Therefore, a continuous spiral space opened by the groove portion of the inner circumferential surface of the first blower tube 140 and the protrusion of the outer circumferential surface of the second blower tube 150 is continuously formed, and the inflowing wind is discharged while rotating in a cyclone shape.

The cyclone wind generated by the inner circumferential surface of the first blower tube 140 and the outer circumferential surface of the second blower tube 150 and the cyclone wind generated by the inner circumferential surface of the second blower tube 150 are discharged ends of the hair dryer 100. Rotation in the same direction causes the cyclone winds to be more strongly rotated and evenly distributed and evenly distributed in a uniform temperature.

Therefore, the wind discharged from the hair dryer is far more powerful at the same temperature, so there is a structural advantage to supply the wind evenly to the hair hidden behind by a large number of hair.

In addition, due to the double structure of the first blower tube 140 and the second blower tube 150, there is an advantage that the noise generated in the interior of the hair dryer 100 is not sounded out.

On the other hand, when a failure occurs in the heater unit 160 or a failure occurs in the fan motor unit 170 and overheating, the second blower tube 150 is made of an insulator, so it is safe for heat transfer. Due to the heavy structure, it takes a long time for the overheated heat to reach the outermost side of the hair dryer 100 has a structural advantage of protecting the user more safely.

Here, it was described as forming a space for generating a cyclone wind by maintaining a constant interval between the first blower tube 140 and the second blower tube 150, but the structure can be formed in contact with each other in close contact with each other.
