The present invention relates to a hair dryer, and more particularly, to a dual type hair dryer having increased airflow by providing a plurality of drive motors, a blowing fan, and a heater coil.

Hair dryer is for drying the wet hair quickly after winding the hair, there are various forms already used, basically, as shown in Figure 1, the discharge port (10a) is formed in the front part and the suction grill in the rear ( 10b) is provided, a blowing fan 12 mounted inside the case 10 and disposed on the suction grill 10b side, and a driving motor 14 for operating the blowing fan 12. ) And a heater coil 16 embedded in the discharge port 10a side of the case 10.

Here, the handle portion 101 is formed at one end of the case 10, the handle portion 101, the operation switch for turning on / off the power supplied to the drive motor 14 and the heater coil (16) ( 18) is provided.

According to the general hair dryer, the outside air is sucked into the case 10 through the suction grill 10b by the blowing fan 12 rotated by the operation of the drive motor 14, and the sucked outside air is a heater coil. Heated while passing through (16), and then discharged to the discharge port (10a).

Therefore, the user can dry the wet hair more quickly in the natural state by using the heated air discharged from the discharge port 10a of the hair dryer.

On the other hand, since the hair dryer is for drying the wet hair more quickly in the natural state as mentioned, it can be seen that the hair drying capacity of the hair dryer is determined by the blowing amount per unit time.

In other words, as the amount of air blown per unit time increases, it is possible to quickly dry the hair. Therefore, various methods for increasing the amount of air blown per unit time have been devised. And a blower fan.

In the case of the method of increasing the rotational speed of the drive motor in the double, there is a problem that the amount of blown air also does not increase to some extent as a result of the limitation of the rotational speed of the drive motor, in the case of using a larger blower fan There is a problem in that the manufacturing cost burden is increased because a large capacity drive motor corresponding to the size of the should be used.

The present invention has been made to solve the above-described problems, it is an object of the present invention to provide a dual-type hair dryer that can effectively increase the amount of air blown by using a plurality of drive motors and blowing fan and heater coil.

Dual type hair dryer provided to achieve the above object, the discharge port is formed in the front portion and the suction grill is provided in the rear portion, a pair of blower fan is built in parallel arranged in the case, for the operation of each blowing fan By controlling each driving motor, each heating heater for heating the outside air sucked into the case by the operation of each blowing fan, and controlling the power supplied to each of the driving motor and the heating heater, the on / off operation and the blowing amount can be adjusted. Including the operation switch to be made.

Here, the case, the cross section is made of an elliptical shape so as to match the parallelly arranged blowing fan.

Hereinafter, embodiments of the present invention will be described in detail with reference to FIGS. 2 to 3B.

Dual type hair dryer according to an embodiment of the present invention, as shown in Figure 2, the discharge port 20a is formed in the front and the suction grill 20b is provided in the back and the case 20, A plurality of blower fans 22, 22 'provided, drive motors 24, 24', and blower fans 22, 22, respectively, for rotational operation of each blower fan 22, 22 '. And each heater coil 26 (26 ') that heats the outside air introduced into the case 20 by the operation of').

Here, the arrangement structure of each of the blower fans 22 and 22 'may be a horizontal parallel type as well as a vertical parallel type, and is preferably made in consideration of the purpose and aesthetics.

The case 20 is preferably made of a shape having an elliptical cross-section that surrounds the outer side of the two blowing fans 22, 22 'arranged in parallel.

In addition, the dual type hair dryer according to the present embodiment controls the power supplied to each of the driving motors 24, 24 ′ and heater coils 26, 26 ′ so that the on / off operation and the airflow amount can be adjusted. It consists of an operation switch 28, the operation switch 28 is provided in the handle portion 201 formed in the case 20, as shown in the off step, one stage blowing step, two stage blowing step It is composed of three stages of ventilation steps.

Here, power is not supplied to each of the driving motors 24 and 24 'and the heater coils 26 and 26' in the off stage of the operation switch 28, and the one side driving motor 24 in the single stage blowing step. And power is supplied only to the heater coil 26, power is supplied only to the other driving motor 24 'and the heater coil 26' in the two-stage blowing step, and all the driving motors 24 and 24 are supplied in the three-stage blowing step. ) And heater coils 26 and 26 'are supplied with power.

Referring to the operation of the dual-type hair dryer according to the present embodiment configured as described above are as follows.

First, when the operation switch 28 is raised in the first stage blowing step in the off state, power is supplied to the one side driving motor 24 and the corresponding heater coil 26, and the air blowing mounted to the one side driving motor 24 is performed. The fan 22 is rotated, and one heater coil 26 is also heated.

Therefore, the outside air is sucked into the case 20 by the rotating one side fan 22, and then discharged through the discharge port 20a while being heated by the one side heater coil 26 (see FIG. 3A).

In this one-stage blowing step, only one blower fan 22 and the heater coil 26 are operated to maintain a blowing amount similar to that of a conventional hair dryer, and to allow soft and relaxed hair drying.

Subsequently, when the operation switch 28 is raised in a two-stage blowing step, the power supply is cut off from the one side driving motor 24 and the heater coil 26 that are in operation, and the other side driving motor 24 'and the heater coil 26' are turned off. The power is supplied to the other blower fan 22 'and the heater coil 26' is operated.

The blowing amount of the two-stage blowing stage is not different from the one-stage blowing stage, but may be used as a spare concept in case one side driving motor 24 and the heater coil 26 are not operated due to a failure. When alternately using the first stage blowing stage and the second stage blowing stage, it is possible to obtain an effect such that durability of both driving motors 24, 24 'and heater coils 26, 26' is improved.

In addition, in the three-stage blowing step, not only the one side driving motor 24 but also the other side driving motor 24 'is operated, and the blowing fan 22' mounted therein is also rotated so that a large amount of outside air is sucked into the case 20. The other heater coil 26 ′ is also operated to discharge a large amount of external air introduced therein after sufficiently heating it (see FIG. 3B).

In this three-stage blowing step, since the air volume is much higher than that of the existing hair dryer, rapid hair drying is possible.

According to this embodiment of the present invention, the maximum airflow is substantially increased as compared with the conventional hair dryer, and compared with the case where the maximum airflow is the same as in this embodiment by using only a large drive motor and a heater coil. In the present embodiment, although the maximum airflow is the same, the power usage efficiency is low because only a small amount of drive motor and heater coil is operated in the present embodiment, compared to the case of operating a large-capacity drive motor and the heater coil in the medium to low air volume stage. Is improved.

As described above, according to the dual type hair dryer according to the present invention, there is an advantage in that the amount of blowing is greatly increased by using a plurality of driving motors and a blowing fan.

In addition, when there is no need to increase the air flow rate, only a small blower fan and a heater coil are used. Therefore, the power usage efficiency is higher and volume and weight are advantageous compared to a method using a large-capacity driving motor and a heater coil. have.
