  However, in the conventional configuration, when the attached stand is used, there is a problem that the number of parts increases and the cost increases. In addition, when a leg-like projecting shape is used, there is a problem that the sense of unity of the design is impaired and the appearance design is affected.

  As another problem, when the cord reel device is mounted in addition to the two high voltage generators, it is necessary to secure a space for arranging the cord reel device in addition to a space for arranging the two high voltage generators. For this reason, there is a concern that the size of the hair dryer main body will increase, or if a high pressure generator is placed on the passage of the wind, the air volume will be reduced, and it is difficult to secure a space. It was.

  Therefore, in view of the above problems, the present invention has an object to provide a hair dryer that does not require a separate part such as an attached stand and that can stand by itself so as to fix the blowing direction without affecting the appearance design. And

  The second object of the present invention is to arrange two high-pressure generators and a cord reel device without increasing the size of the hair dryer main body, and without affecting the air volume by not blocking the passage of the wind. The object is to provide a hair dryer in which a high-pressure generator can be arranged.

In the hair dryer according to the first aspect of the present invention, a motor assembly having a motor and a fan, a heater assembly having a heating element for heating air blown from the fan, and a housing constituting an outline of the motor assembly and the heater assembly, A plurality of high-pressure generators for generating negative ions, and an air inlet provided at the rear of the housing; a cord reel device that is housed in the housing and winds up a cord; At least one of the high-pressure generators is arranged at the center of the rear side of the inlet side of the cord reel device.

According to the first aspect of the present invention, the two high-pressure generators and the cord reel device can be arranged without increasing the size of the hair dryer body. Furthermore, since the high-pressure generator can be arranged so as not to block the passage of the wind, the air volume is not reduced.

It is a side view which shows the inside of the hair dryer in 1st Example of this invention. It is a figure which shows the inside of a heater assembly seen from the direction A of FIG. It is a figure which shows the state by which the handle | steering_wheel of the hair dryer was bent by the predetermined angle same as the above. It is a side view which shows the inside of the hair dryer in 2nd Example of this invention.

  Hereinafter, preferred embodiments of the hair dryer according to the present invention will be described with reference to the accompanying drawings.

  1 to 3 show a hair dryer according to a first embodiment of the present invention.

  As shown in FIG. 1, the dryer body 1 includes a housing 2 that is substantially cylindrical and formed of an electrically insulating synthetic resin molding. The housing 2 has an intake port 3 at the rear and a discharge port 4 at the front. A nozzle 5 is detachably and rotatably mounted on the discharge port 4 so that rectified air is blown to the hair. The housing 2 further includes an air passage 6 that communicates the intake port 3 and the discharge port 4. A cord reel device 7 for winding and storing a power cord (not shown) is disposed inside the housing 2. A motor assembly 8 having a motor and a fan (not shown) is disposed at the center of the housing 2, and a heater assembly 10 having a heating element 9 is disposed in front of the motor assembly 8.

  Further, a high pressure generator 11 that generates negative ions is disposed in front of the heater assembly 10. Although not particularly shown, the high-pressure generator 11 includes a needle-like electrode for generating negative ions and a counter electrode thereof. By applying a high voltage generated by the high voltage generator 11 to the needle electrode and releasing electrons from the needle electrode toward the counter electrode, oxygen in the air is negatively charged and negatively ionized. ing.

  A handle 12 is attached to the lower rear side of the housing 2 so as to be rotatable around a rotation shaft 13. The handle 12 has a flat handle back surface 14. As with the housing 2, the handle 12 is formed of an electrically insulating synthetic resin molding. The handle 12 is fixed in a “use position” that stands up to a position that is nearly perpendicular to the longitudinal direction of the housing 2. Further, the handle 12 is fixed at a “stand position” bent at a predetermined angle from the standing “use position”. The handle 12 is further bent from a predetermined angle and is fixed at a “storage position” that is substantially parallel to the longitudinal direction of the housing 2.

  The cord reel device 7 has terminals 15 and 16. The power cord is connected to each terminal 15 and 16. The cord reel device 7 includes a rotatable reel 18 having flanges 17 at both ends. A power cord is attached to the reel 18, and the power cord is wound around the outer periphery of the reel 18. The power cord led out from the cord reel device 7 is introduced into the handle 12 substantially linearly and exposed from the outlet 19 at the bottom of the handle 12. Therefore, the power cord can be pulled out and wound up smoothly. The terminals 15 and 16 are connected to wirings such as a motor, a heating element 9 and a high voltage generator 11 so that necessary power is supplied.

  On the front surface of the handle 12, a slide type operation switch 21 for turning on / off the power is disposed. The operation switch 21 serves as a motor switch. For example, when the operation switch 21 is in the “OFF” position, the motor is not energized. When the operation switch 21 is in the “SET (weak)”, “DRY (medium)”, or “TURBO (strong)” position, the motor is energized, and the motor rotation speed is divided into three levels depending on the position. It is switched and the air volume is adjusted. Above the operation switch 21, a slide type operation switch 22 for switching between hot air and cold air is disposed. The operation switch 22 serves as a switch for the heating element 9. For example, when the operation switch 22 is in the “HOT” position, the heating element 9 is energized and hot air is blown out from the discharge port. Yes. When the operation switch 22 is in the “COOL” position, the heating element 9 is not energized, and cold air is blown out from the discharge port 4.

  As shown in FIG. 2, the heater assembly 10 inside the housing 2 includes two support plates 25 and 26 formed of mica and a cylindrical support tube 27 that covers the periphery of the support plates 25 and 26. The two support plates 25 and 26 are assembled in a cross shape. With the dryer body 1 in the posture shown in FIG. 1, the support plate 25 maintains a horizontal posture, and the support plate 26 is vertical. Fixed to maintain posture. Grooves are formed in the support plates 25 and 26 to hang the heating elements 9, and the heating elements 9 are spirally wound around the support plates 25 and 26. Further, a recess is formed from substantially the center position of the support plates 25 and 26 to the rear, and the high pressure generator 11 is accommodated in the recess.

  As shown in FIG. 3, the intake port 3 has a plurality of intake surfaces, a first intake surface 31 and a second intake surface 32. The first intake surface 31 is inclined downward from the connection position with the upper housing 2 toward the rear. The second intake surface 32 is a flat surface and is inclined downward from the connection position with the first intake surface 31 toward the front. On the other hand, the handle back surface 14 is also a flat surface, and when the handle 12 is fixed at the “stand position” bent at a predetermined angle, the handle back surface 14 and the second air intake surface 32 become the same line upper surface. Yes. That is, the second intake surface 32 is configured such that when the handle 12 is fixed at the “stand position”, the line L1 on the back surface of the handle and the line L2 on the second intake surface are substantially in a straight line. Here, the back face line L1 is a line formed along the surface of the handle back face 14 when the handle 12 is viewed from the side. The line L2 on the second intake surface is a line formed along the surface of the second intake surface 32 when the intake port 3 is viewed from the side.

  Next, the operation of the hair dryer configured as described above will be described. To use this hair dryer, first elevate the handle 12 and fix it in the “use position”, pull out the power cord from the outlet 19 for the required length, and connect the power plug (not shown) to the outlet of the commercial AC power supply. Connecting. When the power cord is pulled out, the reel 18 of the cord reel device 7 rotates, and a mainspring spring (not shown) is accumulated. When the operation switch 21 is operated, the fan is rotated by driving the motor, and air is sucked from the intake port. The sucked air passes through a ventilation path including a heater assembly having a heating element and is discharged from a discharge port. At this time, when the heating element 9 is energized, the air is heated by the heating element 9 and hot air is discharged from the discharge port 4.

  At the same time, as the air passes through the high pressure generator 11, negative ions are mixed into the air as needed, and negative ions are supplied to the hair. Passy hair is positively charged and the moisture contained in the hair is taken away. It is said that when negative ions are sprayed on the hair, the negative ions combine with moisture in the air and promote the penetration of moisture into the hair. In addition, since negative ions neutralize static electricity, it is said that moisture is confined in the hair and the moisture of the hair is maintained.

  For example, if the user wants to dry her hair using both hands freely, the position of the handle 12 is fixed at the above-mentioned “stand position”, and the back 14 of the handle and the second air intake surface 32 are the bottom, and the flat stability Put the dryer body 1 in the place. If it does so, the dryer main body 1 can become independent with the discharge port 4 facing a predetermined angle. That is, since the blowing direction can be fixed in a predetermined direction, the user can freely dry the hair using both hands.

  Conventionally, the blowing direction has been fixed using an attached stand separate from the dryer body 1 or a leg-like protruding shape. In contrast, the hair dryer of the present embodiment has a simple configuration in which the handle back surface 14 and the second air intake surface 32 are flush with each other when the handle 12 is fixed at the “stand position” at a predetermined angle. The dryer body 1 is independent. That is, the air blowing direction is fixed at a predetermined angle by placing the handle rear surface 14 and the second air intake surface 32 on the lower surface with respect to a plane having a predetermined height. Therefore, since an attached stand is not necessary, the number of parts can be reduced, and cost reduction can be realized. Further, since the shape of the leg-like protrusion is not required, the design sense of unity as a hair dryer is not impaired, and the appearance design is not adversely affected.

  After using the hair dryer, the power plug is removed from the outlet, and the power cord is wound around the cord reel device 7 and stored. In order to wind the power cord around the cord reel device 7, for example, by pressing an operation button (not shown) provided on the upper portion of the housing, the braking of the reel 18 of the cord reel device 7 is released. Then, the reel 18 rotates in the direction opposite to that when the power cord is pulled out by the force of the mainspring spring, and the power cord is wound around the cord reel device 7. Then, the dryer body 1 can be stored in a compact size by folding the handle 12 to the “storage position” described above.

As described above, in this embodiment , the motor assembly 8 including a motor and a fan, the heater assembly 10 including the heating element 9 that heats the air blown from the fan, and the outline of the motor assembly 8 and the heater assembly 10 are described. , A housing 12 that is foldably connected to the housing 2, has a flat handle back surface 14, and can be fixed at a folding position, and is provided at the rear of the housing 2, and has a plurality of air intake surfaces. And at least one of the plurality of intake surfaces is a flat surface, and the line L2 on the intake surface is a line L1 on the back surface of the handle at a position where the handle 12 is bent at a predetermined angle. By making it approximately straight, it can stand on its own to fix the blowing direction without using separate parts such as an attached stand. The number of items can be reduced, and cost reduction can be realized. Further, since the shape of the leg-like protrusion is not required, the design sense of unity as a hair dryer is not impaired, and the appearance design is not adversely affected.

  Next, the hair dryer in 2nd Example of this invention is demonstrated based on FIG. In addition, the same code | symbol is attached | subjected to the same part as the said 1st Example, and since the description of the common location overlaps, it abbreviate | omits. As for the action, the description of the same action as in the first embodiment is omitted.

  As described in the first embodiment, the dryer main body 1 includes one high-pressure generator 11 inside the housing 2 and the cord reel device 7 behind the high-pressure generator 11. In the present embodiment, another high-pressure generator 41 is disposed at the center of the rear portion of the cord reel device 7 on the intake port 3 side. That is, the high pressure generator 41 is disposed in a cavity formed inside the reel 18 of the cord reel device 7.

  With the above configuration, the two high-pressure generators 11 and 41 and the cord reel device 7 can be arranged without increasing the size of the dryer body 1. Further, since the high pressure generators 11 and 41 can be arranged so as not to block the passage of the wind, the air volume is not reduced. A sufficient space for the high-pressure generator can be secured only by the space for the cord reel device 7. By arranging the two high-pressure generators 11 and 41 in the wind path in this way, the hair of the hair dryer 1 is increased without increasing the size of the dryer body 1 as compared with the case of one high-pressure generator. Can be supplied to.

As described above, this embodiment corresponds to claim 1 , and includes a motor assembly 8 having a motor and a fan, a heater assembly 10 having a heating element 9 for heating air blown from the fan, and the motor.

By arranging in the center, the two high-pressure generators 11 and 41 and the cord reel device 7 are arranged without increasing the size of the dryer body 1 and the passage of the wind is blocked. Therefore, the high pressure generators 11 and 41 can be arranged without affecting the air volume.

  In addition, this invention is not limited to the said Example, It can change in the range which does not deviate from the meaning of this invention. For example, in the first embodiment, the case where there is one “stand position” to which the handle 12 is fixed and the number of intake surfaces is two has been described. However, a plurality of “stand positions” are provided, and the intake port 3 Three or more intake surfaces may be provided, and the blowing direction may be fixed in multiple stages. In the second embodiment, the number of high-pressure generators is two, but three or more high-pressure generators may be arranged.
