The present invention relates to a heating device for a hair dryer, and to a heating device for a hair dryer that uniformly distributes the temperature and wind speed of the warm air, thereby facilitating control of heat generated from the heating wire and reducing noise. As shown in FIG. 1, a conventional hair dryer to which a heat transfer device is applied, a handle 3 is formed at the lower portion of the body 1 to easily hold the hair dryer, and a lower portion of the handle 3 is provided to the hair dryer. The power cord 5 is connected to supply power. The blowing means 6 is disposed inside the body 1 to suck air into the inside of the body 1. At this time, the blowing means 6 is composed of a fan 7 and a motor disposed on one side of the fan 7 to generate power for operating the fan 7. One side of the blower means 6 is provided with heat transfer means 11 to heat the air sucked into the body 1 by the fan 7, and the heat transfer means 11 is provided with the heat transfer means 11. The supporting means 13 are arrange | positioned so that it may support. At this time, the body 1 is generally cylindrical. In addition, a plurality of through holes 1a are formed at one side of the body 1 to allow air to flow into the body 1, and a plurality of ribs 1b are configured to support the motor 9. It is formed in the inner peripheral surface of 1). The handle 3 is provided with a switch means 15 to operate the hair dryer and to adjust the operation at the same time. As shown in FIG. 2, the heat transfer means 11 has a structure in which a coil spring type heat transfer wire 17 is wound around the outer surface of the support means 13 in a screwed manner. The support means 13 has a structure in which a plurality of plates 19 having a rectangular plate shape are combined in a cross shape and fixed to an inner circumferential surface of the body 1. Therefore, four spaces 13a, 13b, 13c, and 13d are formed between the support means 13 and the body 1. At this time, a plurality of grooves 19a are formed at the edges of the plate 19 so that the heating wires 17 of the heat transfer means 11 are screwed. At this time, the groove 19a is generally half-moon-shaped. In the conventional hair dryer having the heating device configured as described above, when the power cord 5 is connected to a power supply means (not shown), the switch means 15 is operated to supply power to the motor 9 and the heating wire 17. Is supplied and the motor 9 rotates. The fan 7 rotates as the motor 9 rotates, and the suction force for the air is generated by the fan 7 so that the surrounding air is indicated by the arrow C in FIG. Flows into the body (1) through through holes (1a). At the same time, the heating wire 17 generates heat, and the heat generated from the heating wire 17 is transferred to the air introduced into the body 1, and the heated air is discharged in the direction of arrow D in FIG. By the way, in the heating apparatus of the conventional hair dryer comprised in this way, since the heating wire 17 of the coil spring type | mold is wound by the said support means 13, the pitch P1 of the heating wire 17 wound by the said support means 13 ( Not shown in FIG. 3). Therefore, since the calories in each of the spaces 13a, 13b, 13c, and 13d are not constant with each other, there is a problem that the temperature of air discharged through the spaces 13a, 13b, 13c, and 13d is not constant. In addition, since the amount of heat in each of the spaces 13a, 13b, 13c, and 13d is different, the fan based on the space with the highest amount of heat in order to limit the maximum temperature of the air passing through each of the spaces 13a, 13b, 13c, and 13d. (7) had to be driven, there was a problem that power is wasted. In addition, there is a problem that the noise is severe due to air howling into the heating wire 17 on the coil. Therefore, the present invention has been made to solve the above problems, the object of the present invention is to change the shape of the heating wire disposed on the support means, by uniformly distribute the temperature and wind speed of the warm air flowing in the body to control the heat generated from the heating wire It is to provide a heat transfer device of the hair dryer to reduce the noise at the same time to facilitate. The heat transfer device of the hair dryer according to the present invention made to achieve the above object, in the hair dryer having a blowing means to let the air in and out of the body, to be disposed in the body to heat the air sucked in the body And a support means disposed in the body to support the heat transfer means and a heat transfer means having a sine curve type heating wire. Hereinafter, an embodiment of the present invention will be described in detail with reference to the accompanying drawings. In addition, the same code | symbol is attached | subjected about the part same as the part shown in FIG. 1, and the overlapping description is abbreviate | omitted. As shown in FIG. 4, a heat transfer means 21 is disposed inside the body 1 to heat the air sucked into the body 1, and the heat transfer means 21 is disposed on the heat transfer means 21. The support means 23 are arrange | positioned so that it may support. The heat transfer means 21 has a structure in which a sinusoidal heating wire 25 is wound around the outer surface of the support means 23 by a screw type. The heating wire is a large resistance wire made of nichrome wire and the like, and both ends thereof are connected to a control means (not shown) so that power is supplied and cut off by the switch means. The support means 23 has a structure in which a plurality of plates 27 having a rectangular plate shape are combined in a cross shape and fixed to an inner circumferential surface of the body 1. Therefore, four spaces 23a, 23b, 23c, and 23d are formed between the support means 23 and the body 1. At this time, a plurality of grooves (27a) is formed at the edge of the support means 23 so that the heating wire 25 of the heat transfer means 21 is screwed. At this time, the groove 27a is substantially V-shaped. The operation and effects of the heat transfer device of the hair dryer according to the embodiment of the present invention configured as described above will be described below. Air introduced into the body 1 in the direction of arrow E in FIG. 1 is heated by the heat generated from the heating wire 25 and is discharged in the direction of arrow F. As shown in FIG. At this time, the heating wire 25 is a sine curve type (sine curve) wound around the support means 23, so that the pitch P2 (shown in FIG. 6) of the heating wire 25 wound on the support means 23 is It becomes constant. Therefore, since the heat amount in each of the spaces 23a, 23b, 23c, and 23d is uniformly distributed to each other, the temperature of the air discharged through the spaces 23a, 23b, 23c, and 23d becomes constant. Therefore, since the temperature of the air flowing in each of the spaces 23a, 23b, 23c, and 23d is constant, temperature control is easy and power consumption for driving the fan 7 is reduced. In addition, since the air resistance hitting the sine curve type heating wire 25 is small, the noise is small. As described above, the heating device of the hair dryer according to the present invention has the shape of a sine curve type heating wire disposed on the supporting means, thereby uniformly distributing the temperature and wind speed of the warm air flowing in the body, thereby generating heat generated from the heating wire. It is a very practical design that facilitates adjustment and reduces noise at the same time.
