Description

The present invention relates to a hair dryer provided with a hair styling body such as a brush or a comb.

Regarding this type of hair dryer, for example, a wave comb to be attached to the dryer of Patent Document 1 is known. There, a wave comb is detachably attached to the outlet of the dryer (hair dryer). The wave comb is integrally equipped with a mounting ring that is attached to and detached from the outlet, and a comb that protrudes from the mounting ring in parallel with the dry air blowing center line. It has orthogonal teeth. When using a wave comb, attach a mounting ring to the outlet of the dryer, blow hot air with the comb teeth on the base of the hair forming the wave, and use the crimping comb to blow the hair. Bend the tip side to make a habit. If the dryer is used to dry the hair, remove the wave comb from the outlet.

Gazette No. 37-13421

In the wave comb of Patent Document 1, since the teeth of the comb are provided at right angles to the center line of the hot air, there is a problem in usability when the hair is combed and dried. Specifically, in order to comb the hair with the wave comb of Patent Document 1, it is necessary to move the dryer along the center line of the blowing air of the drying air, so it is necessary to dry the hair while combing it in an unreasonable posture. In particular, it is extremely difficult to dry the hair on the back of the head while combing it by yourself. In addition, when not in use, the wave comb needs to be removed from the outlet and stored, but it is often forgotten where to store it, or it is often mixed with other beauty equipment, so it is for waves. There is also the inconvenience of not being able to use the comb immediately if you want to use it.

An object of the present invention is to provide an easy-to-use hair dryer that can effectively perform the work of combing and drying hair with a hair styling body in a comfortable posture at all times, and can immediately use the hair styling body when necessary. To do.

In the hair dryer of the present invention, the hair trimming body 21 is supported by the main body case 1 so as to be able to change the posture between the hair trimming posture and the accommodating posture, and the hair shaping element 31 of the hair trimming body 21 in the hair trimming posture faces the blowout region of the dry air. I did it. Further, in the hair-dressing body 21 in the accommodation posture, the hair-dressing element 31 is retracted from the dry air blowing region and is housed along the periphery of the main body case 1. According to such a hair dryer, the work of combing and drying the hair with the hair trimming body 21 can be effectively performed in a comfortable posture at all times. Further, since the hair trimming body 21 is always provided around the main body case 1, the hair trimming body 21 can be immediately ready to be used when necessary, and a hair dryer having excellent usability as a whole can be provided.

The hair styling body 21 has a support base 30 projecting along the dry air blowing central axis P in the hair styling posture, and a hair styling body projecting from the support base 30 toward the dry air blowing central axis P in multiple rows. It is composed of a group of elements 31. According to the hair dryer provided with such a hair styling unit, the hair can be dried while being combed by the hair styling body 21 by moving the hair dryer in a direction intersecting the center line P of the blowing air of the dry air, which is a conventional dryer. Compared to, hair treatment can be performed in a natural and comfortable posture. Further, since the hair styling body 21 is provided with a group of hair styling elements 31 projecting in multiple rows, the amount of hair styling elements suitable for various hair treatments such as hair drying, combing, and habituation is provided. It is possible to effectively perform hair treatment by capturing with 31 in just proportion.

A posture detection switch 61 is provided in the main body case 1, and in a state where the posture detection switch 61 detects that the hairdressing body 21 has been switched to the hairdressing posture, the control unit 15 increases the drive rotation speed of the motor 12. Alternatively, the calorific value of the heater 13 is reduced. According to such a hair dryer, the temperature of the dry air sent to the hair captured by the hair styling body 21 can be lowered to eliminate the excessive hot air sent to the hair, so that the hair can be prevented from being excessively sent to the hair. Hair treatment can be suitably performed without causing damage.

When the angle between the grip center axis R of the main body grip 2 and the vertical line Q is θ, the angle between the hair shaping axis S of the hair shaping body 21 switched to the hair shaping posture and the drying air blowing center axis P is the angle θ. I tried to set it to the same as. In this way, if the inclination of the hair styling body 21 is set in relation to the inclination of the main body grip 2, the hair styling body 21 and the main body are used when the hair is dried or combed while the main body grip 2 is held. It is not necessary to move the hair dryer while correcting the difference in the inclination of the grip 2. Therefore, the hair drying or combing work can be easily performed in a comfortable posture.

When the hair styling element 31 intersects with the extension shape line K of the opening edge of the air outlet 5, the hair captured by the bristle 31 with a strong flow of dry air sent from the outlet 26 of the hair styling nozzle 20. Can be sprayed on. Therefore, it is possible to effectively perform hair treatment such as drying or habituation while combing the hair.

A turning mechanism 22 is provided facing the outlet 5 of the main body case 1, and the changing plate 48 is switched to the changing posture by the changing plate operating body 49 in conjunction with the switching of the hair shaping body 21 to the hair shaping posture. Then, the dry air sent from the blower fan 11 can be directed toward the hairdressing body 21. According to such a hair dryer, most of the dry air sent from the outlet 5 can be guided in a flow toward the hair brush 21, so that the hair can be dried and habituated more effectively.

The hairdressing body 21 is composed of a linear axis-shaped support base 30 and hair shaping elements 31 arranged in rows along the base 30, so that the hair shaping body 21 can be inverted and rotated around a support shaft 36 with respect to the main body case 1. I tried to support it. According to such a hair shaping unit, the posture of the hair shaping body 21 can be switched between the accommodating posture and the hair shaping posture only by reversing and rotating the hair shaping body 21, so that, for example, the hair shaping body 21 is slid back and forth to switch the posture. Compared to such a case, the posture of the hairdressing body 21 can be switched immediately by one-touch operation.

If the hair styling unit is attached to the hair styling body 21, the conversion mechanism 22, and the hair styling nozzle 20 that supports both of these 21 and 22, the weight of the main body case 1 in the state where the hair styling unit is removed can be reduced, so that the main body case can be reduced. The hair dryer can be handled lightly when the hair is dried with only 1.

In a hair dryer provided with an auxiliary nozzle 70, if the auxiliary nozzle 70 is provided with a dummy pin 74, the dummy pin 74 is engaged and captured by the connection terminal 67 in a state where the auxiliary nozzle 70 is engaged and mounted on the accessory mounting portion 8. Therefore, the mounting strength of the auxiliary nozzle 70 can be increased accordingly. Therefore, even when a collision impact or a drop impact acts on the main body case 1 or the auxiliary nozzle 70, it is possible to prevent the auxiliary nozzle 70 from being separated from the main body case 1.

The auxiliary grip 90 attached to the suction port 4 of the main body case 1 is provided with a grip shaft portion 92 projecting along the central shaft P for blowing dry air.

Can be operated. Therefore, the work of combing and drying the hair with the hairbrush 21 and the work of squeezing the hair can be effectively performed in a more comfortable posture. Also, during drying work, the position of the hand holding the grip shaft portion 92 and the position of the hair brush 21 that captures the hair are far apart, so the hair combing condition and finish condition can be clearly visually observed before use. It is possible to properly perform the habit processing intended by the person.

If the grip shaft portion 92 of the auxiliary grip 90 is formed of a breathable tubular shaft that communicates with the inside of the mounting portion 91, air is sucked into the main body case 1 through the grip shaft portion 92 and the suction port 4. Therefore, the intake resistance at the suction port 4 can be reduced. Therefore, even though the mounting portion 91 of the auxiliary grip 90 is fitted and mounted on the suction port 4, the hair can be dried and curled without any trouble.

According to the intake opening 95 formed in the mounting portion 91 and the auxiliary grip 90 for sucking external air from the intake port 97 formed at the tip of the grip shaft portion 92, the intake resistance in the suction port 4 is further reduced, and further. A large amount of external air can be taken into the main body case 1. Therefore, it is possible to more effectively dry and habit the hair by making the amount of dry air supplied from the outlet 5 sufficient.

By mounting the mounting portion 91 on the mounting surface and mounting the mounting portion 2a of the main body grip 2 on the grip shaft portion 92, the auxiliary grip 90 also serves as a stand for the main body case 1. As described above, according to the usage mode in which the auxiliary grip 90 is used as a stand for the hair dryer, the hair can be treated in a hands-free state with both hands while supplying dry air to the hair, so that the hair can be dried. The usability of the hair dryer can be further improved by diversifying the hair treatment such as habituation.

In a state where the hair shaping body 21 is switched to the hair shaping posture, the support base 30 inclines downward from the side of the outlet 5 of the main body case 1 toward the base tip side, and the hair shaping element 31 on the base tip side is the center of blowing dry air. It was made to intersect the axis P. According to such a hair conditioning unit, when the hair is dried while being combed with the hair brush 21, the hair captured by the bristle 31 can be directly blown with a vigorous dry air near the blowout central axis P. Further, since the hair brush 21 is tilted downward and the dry air is blown to the hair captured by the bristle 31, the structure of the hair conditioning unit can be simplified and the cost can be reduced as compared with the case where the conversion mechanism 22 is separately provided.

In the hairdressing unit provided with the hairdressing nozzle 20 and the hairdressing body 21, the hairdressing nozzle 20 is rotatably supported by the main body case 1 around the central axis P for blowing dry air, and is provided between the main body case 1 and the hairdressing nozzle 20. With a modest structure, the hairdressing nozzle 20 can be engaged and held at regular rotation angles. According to such a hair styling unit, the hair styling nozzle 20 and the hair brush 21 can be rotated to hold the position at the user's favorite position, so that the hair can be effectively dried and curled as a whole in a comfortable posture. Can be done.

Further, by supporting the boss portion 34 of the base shaft body 29 with the support shaft 36 provided on the bracket 35 of the hair shaping nozzle 20, the entire hair brush 21 can be changed in posture between the hair shaping posture and the accommodating posture. .. In this way, when the hairbrush 21 is rotatably supported around the support shaft 36 in the main body case 1, the posture of the hairbrush 21 can be changed to the accommodating posture simply by operating the hairbrush 21 in reverse rotation. Since the posture can be switched to the hair-dressing posture, the posture of the hairbrush 21 can be switched immediately by one-touch operation, as compared with the case where the hair-dressing body 21 is slid back and forth to switch the posture. Further, by rotating the brush main body 28 around the engaging shaft 32 with respect to the basic shaft body 29, the posture of the brush main body 28 can be changed in various ways. For example, when the body grip 2 is gripped and the hair on the side surface of the head is trimmed, the brush body 28 is turned downward as shown by the solid line in FIG. 1, and when the hair on the back surface of the head is trimmed, FIG. By turning the brush body 28 upward as shown by the imaginary line, it is easy to arrange the hair and the usability can be improved. When the brush body 28 is turned upward, warm air cannot be directly sent to the hair captured by the bristle 31, but it is possible to perform hair styling and drying by alternately sending warm air and combing the hair. can. As described above, the brush main body 28 in the hair shaping posture is rotatably attached to the base shaft body 29 around an axis parallel to the blowout central axis P.

As shown in FIG. 1, when the hairbrush 21 is in the hair shaping posture, the hairbrush 21 protrudes from the front end portion of the main body case 1 on the outlet 5 side, and the bristle 31 faces the dry air blowing region. Further, in the state where the hairbrush 21 is in the accommodating posture, as shown in FIG. 2, the bristle 31 is retracted from the dry air blowing region, and the hairbrush 21 is accommodating along the periphery of the main body case 1. The dry air blowing region is a region where the dry air supplied from the outlet (final outlet) 26 of the hair conditioning nozzle 20 reaches without impairing the momentum of the flow, and the destination with the outlet 26 as the base end. It is a wide and tapered space. Therefore, the fact that the bristle 31 faces the blowout region of the dry air includes a form in which the tip of the bristle 31 is located above the extension shape line K in the hair shaping posture.

In order to effectively bring the dry air into contact with the hair combed by the hairbrush 21, the tip of the bristle 31 intersects the extension shape line K of the opening edge of the outlet 26 when the hairbrush 21 is in the hair shaping posture. ing. As shown in FIG. 1, the extension shape line K has the same diameter as the diameter of the opening edge of the outlet 26, and is a virtual shape line when assuming a circumferential surface around the central axis P for blowing dry air. In this way, when the tip of the bristle 31 intersects the extension shape line K, the dry air with a strong flow sent from the outlet 26 of the hair shaping nozzle 20 is blown onto the hair captured by the bristle 31. be able to. Therefore, it is possible to effectively perform hair treatment such as drying or habituation while combing the hair.

In order to hold the position of the hairbrush 21 in the hair shaping posture and the accommodating posture, a first moderation structure is provided between the boss portion 34 of the base shaft body 29 and one of the brackets 35. As shown in FIG. 5, the first moderation structure includes a moderation ball 39 housed in the boss portion 34, a compression spring 40 for pushing out and urging the ball 39, and two moderation recesses formed indentations on the side of the bracket 35. It is composed of 41. As described above, the brush body 28 is connected to the base shaft body 29 via the engaging shaft 32, and the engaging shaft 32 is rotatably supported by the engaging hole 33. Therefore, the direction in which the bristle 31 protrudes can be changed according to the user's preference by rotating the brush body 28 around the engaging shaft 32 after the hair brush 21 is in the hair shaping posture. Further, in order to hold the bristle 31 at a position desired by the user, a second moderation structure is provided between the joint surface between the brush main body 28 and the base shaft body 29. Similar to the first moderation structure, the second moderation structure includes a moderation ball 43 housed on the side of the base shaft body 29, a compression spring 44 for pushing out and urging the ball 43, and a recess formed on the side of the brush body 28 8 It is composed of a moderation recess 45, and can hold the position every time the brush body 28 is rotated by 45 degrees.

It is built in. In FIGS. 1 and 4, the turning mechanism 22 is a turning plate 48 that is supported by the tubular wall of the hair shaping nozzle 20 so as to be swingable up and down, and a turning plate that simultaneously switches between these turning plates 48. It is composed of an operating body 49 and a return spring 50 made of a leaf spring that pushes up and urges the turning plate operating body 49. The turning plate 48 has a rounded trailing edge and is formed in an airfoil-shaped cross section that points toward the leading edge, and a long hole 51 that is oscillated by the turning plate operating body 49 is formed on the trailing edge. The turning plate operating body 49 is projected upward from the operating arm 53 orthogonal to the left and right center on the rear side of the turning plate 48, the spring receiving seat 54 continuous to the upper end of the operating arm 53, and the spring receiving seat 54. It is composed of a plastic molded product integrally provided with a passive shaft 55 and a switching piece 56 projecting rearward from the passive shaft 55. The upper portion of the passive shaft 55 projects so as to face the swing region of the base shaft body 29.

Each turning plate 48 and the turning plate operating body 49 are connected to an operating pin 57 fixed to the turning plate operating body 49 via an elongated hole 51. Therefore, in the state where the hairbrush 21 is switched to the hair shaping posture, the changing plate operating body 49 is pushed down against the urging force of the return spring 50, and the changing plate 48 is haired as shown in FIG. It is possible to switch to the uphill inclined posture toward the brush 21. Further, in the state where the hairbrush 21 is switched to the accommodation posture, the changing plate operating body 49 is pushed up by the return spring 50, and as shown in FIG. 4, the changing plate 48 is blown out by the dry air central axis P. Return to the standby posture along with. In this way, the turning plate 48 of the turning mechanism 22 is operated to switch from the standby posture to the turning posture in conjunction with the switching of the hairbrush 21 from the accommodating posture to the hair shaping posture. In the state where the changing plate 48 is switched to the changing posture, most of the dry air sent from the outlet 5 can be guided to the hair brush 21, so that the hair can be effectively dried and curled. It can be carried out.

On the other hand, if a high temperature dry air is excessively supplied, there is a risk of damaging the hair. In order to solve such a problem, a posture detection switch 61 is provided inside the switch section 60 above the hairdressing nozzle 20 so that the hot air of high temperature can be eliminated. The posture detection switch 61 is composed of an upper switch terminal 62 and a lower switch terminal 63, and when the hairbrush 21 is switched to the hair shaping posture, the upper switch terminal 62 is pushed down by the switching piece 56. By being operated, both terminals 62 and 63 are conducted and turned on (see FIG. 1). Further, in the state where the hairbrush 21 is switched to the accommodation posture, the upper switch terminal 62 and the switching piece 56 move upward, and both terminals 62 and 63 are separated and turned off (see FIG. 4). The return spring 50, the spring seat 54, the passive shaft 55, and the switching piece 56 are also housed inside the switch compartment 60.

The connector 65 is composed of a pair of connector pins 66 fixed to the hairdressing nozzle 20 and conducting with each of the switch terminals 62 and 63, and a pair of connection terminals 67 provided on the side of the main body case 1. Each connection terminal 67 is connected to the control unit 15 via a terminal plate and a connection lead. When an ON signal is output from the attitude detection switch 61 to the control unit 15 when the hair dryer is used, the control unit 15 reduces the heat output of the heater 13 from the preset output as shown in FIG. 7A. The calorific value is reduced to lower the temperature of the warm air. Alternatively, as shown in FIG. 7B, when an ON signal is output from the attitude detection switch 61 to the control unit 15, the control unit 15 increases the drive rotation speed of the motor 12 from a preset rotation speed to heat the motor 12. Reduce the temperature of the wind. If necessary, control for reducing the heat output of the heater 13 and control for increasing the drive rotation speed of the motor 12 may be performed at the same time. Further, when the hair brush 21 is switched to the accommodation posture, both terminals 62 and 63 are conductive and switched to the on state, and when the hair brush 21 is switched to the hair conditioning posture, both terminals 62 and 63 are separated. The attitude detection switch 61 may be configured to switch to the off state. In that case, the control unit 15 controls to reduce the heat output of the heater 13 and the motor 12 so that the normal warm air is supplied in the accommodating posture and the temperature of the warm air is lowered in the hair conditioning posture. It suffices to perform at least one of the controls for increasing the drive rotation speed of.

In order to further strengthen the auxiliary nozzle 70, a boss portion 73 is formed in a bulge on the upper surface thereof, and a dummy pin 74 that engages with the connection terminal 67 is provided on the rear surface thereof. In this way, when the dummy pin 74 is engaged with the connection terminal 67 in the state where the auxiliary nozzle 70 is mounted on the accessory mounting portion 8, the auxiliary nozzle 70 and the main body are equal to the engagement strength between the dummy pin 74 and the connection terminal 67. Since the connection strength of the case 1 can be increased, it is possible to prevent the auxiliary nozzle 70 from being separated from the accessory mounting portion 8 by receiving an external force such as a collision impact or a drop impact.

According to the hair dryer according to the first embodiment configured as described above, the work of combing and drying the hair with the hairdressing body 21 and the work of curling the hair can always be effectively performed in a comfortable posture. Further, since the hair trimming body 21 is always provided around the main body case 1, the hair trimming body 21 can be immediately ready to be used when necessary, and a hair dryer having excellent usability as a whole can be provided.

The hair trimming body 21 in the first embodiment has a support base 30 projecting along the dry air blowing central axis P in the hair trimming posture, and projecting from the support base 30 toward the dry air blowing central axis P in a multi-row shape. It is composed of a group of hair conditioning elements 31 to be provided. According to the hair dryer provided with such a hair styling unit, the hair can be dried while being combed by the hair styling body 21 by moving the hair dryer in a direction intersecting the center line P of the blowing air of the dry air, which is a conventional dryer. Compared to, hair treatment can be performed in a natural and comfortable posture. Further, since a group of hair shaping elements 31 projecting in multiple rows is provided on the hair shaping body 21, an amount of hair suitable for various hair treatments such as hair drying, combing, and habituation is provided by the hair shaping element 31. It can be captured without excess or deficiency, and hair treatment can be performed effectively.

Further, in the hair dryer according to the first embodiment, the posture detection switch 61 is provided in the main body case 1, and when the posture detection switch 61 detects that the hair shaping body 21 has been switched to the hair shaping posture, the control unit 15 is a motor.

According to such a hair dryer, in a state where the hair bundle is captured by the hair styling body 21, the temperature of the dry air sent to the hair bundle is lowered, and the hot air is excessively sent to the hair bundle. Therefore, it is possible to suitably perform hair treatment without damaging the hair.

(Example 2) FIG. 9 shows a hair dryer according to the second embodiment of the present invention. There, the hairbrush 21 is composed of the brush main body 28 and the base shaft body 29 as in the first embodiment, but a connecting portion 77 for supporting the hair brush 21 is provided on the upper part of the hair shaping nozzle 20 and the base shaft body 29 is provided. The support shaft 36 projecting from the lower surface is rotatably supported by the connecting portion 77 so that the posture of the hairbrush 21 can be changed around the vertical axis. In the state where the hairbrush 21 is in the hair shaping posture, the hairbrush 21 protrudes from the front end portion on the air outlet 5 side of the main body case 1, and the bristle 31 faces the dry air blowing region. Further, in the state where the hairbrush 21 is in the accommodation posture, as shown by the imaginary line, the bristle 31 retracted from the dry air blowing region faces the upper peripheral surface of the main body case 1. In order to maintain the position of the hairbrush 21 in the hair shaping posture and the accommodating posture, a moderation structure equivalent to the first moderation structure is provided between the base shaft body 29 and the connecting portion 77. This moderation structure is composed of a moderation ball 39, a compression spring 40, and a moderation recess 41. In the state where the hairbrush 21 is switched to the hair shaping posture, the changing plate operating body 49 can be pushed down by the base shaft body 29 to switch the changing plate 48 to the uphill inclined posture. Others are the same as in the first embodiment, so the same members are designated by the same reference numerals and the description thereof will be omitted. The same shall apply to each of the following examples.

(Example 3) FIG. 10 shows a hair dryer according to the third embodiment of the present invention. There, a brush accommodating portion 79 is provided from the front end to the rear end of the upper part of the main body case 1, and the hair brush 21 accommodated in the brush accommodating portion 79 is slid back and forth so as to switch between the hair shaping posture and the accommodating posture. did. Therefore, an operation knob 80 is provided on the upper surface of the rear end of the support base 30 of the hairbrush 21 so that the knob 80 can be slid along the guide groove 81 opened in the upper wall of the brush accommodating portion 79. Further, the bristle 31 of the hair brush 21 is supported by a pin 82 fixed to the support base 30 so as to be undulating, and when the hair brush 21 is housed in the brush accommodating portion 79, the bristle 31 is laid down and stored along the support base 30. I made it possible.

(Example 4) FIG. 11 shows a hair dryer according to the fourth embodiment of the present invention. There, a comb (hairdressing body) 21 is composed of a support base 30 and a group of comb teeth (hairdressing elements) 31 projecting from one side of the base 30, and the comb 21 is used as the hairbrush 21 of the third embodiment. Similarly, the slide can be taken in and out of the brush accommodating portion 79 provided in the main body case 1. Therefore, an operation knob 80 is provided on the upper surface of the rear end of the support base 30 of the comb 21 so that the knob 80 can be slid along the guide groove 81 opened in the upper wall of the brush accommodating portion 79.

(Example 5) FIG. 12 shows a hair dryer according to the fifth embodiment of the present invention. There, the inclination of the hairbrush 21 in the state of being switched to the hair shaping posture is set in relation to the inclination of the main body grip 2 in the first use posture, and the hair shaping work performed while holding the main body grip 2 can be easily performed. Moreover, I made it possible to do it accurately. Specifically, assuming a dry air blowout center axis P and a vertical line Q orthogonal to the blowout center axis P, the grip center axis R of the main body grip 2 projecting from the lower surface of the main body case 1 and the vertical line Q are When the pinching angle is θ, the angle between the hair shaping axis S of the hair shaping body 21 switched to the hair shaping posture and the dry air blowing center axis P is set to be the same as the angle θ. The angle θ can be selected within the range of 0 to 25 degrees. In this way, if the tilt angle of the hair brush 21 is set to be the same as the tilt angle θ of the main body grip 2, the hair styling body 21 is used when the hair is dried or combed while holding the main body grip 2. It is not necessary to move the hair dryer while correcting the difference in inclination between the main body grip 2 and the main body grip 2. Therefore, the hair drying or combing work can be easily performed in a comfortable posture.

(Example 6) FIG. 13 shows a hair dryer according to the sixth embodiment of the present invention. There, as in the first embodiment, the hair styling unit is composed of a hair styling nozzle 20 and a hair brush 21 that is rotatably supported around the support shaft 36, but the hair brush 21 is switched to the hair styling posture. In the state, the support base 30 is inclined downward from the side of the outlet 5 of the main body case 1 toward the tip side of the base, which is different from the first embodiment. In a state where the hairbrush 21 is tilted downward and switched to the hair shaping posture, the bristle 31 on the tip side of the base intersects the central axis P for blowing dry air. Further, a moderation structure equivalent to that of the first moderation structure is provided on the joint surface between the hair conditioning nozzle 20 and the accessory mounting portion 8, and the hair conditioning nozzle 20 and the hair brush 21 are positioned at 4 to 8 positions around the central axis P. I made it possible to hold it. This moderation structure is composed of a moderation ball 39, a compression spring 40, and a moderation recess 41.

According to such a hair conditioning unit, when the hair is dried while being combed with the hair brush 21, the hair captured by the bristle 31 can be directly blown with a vigorous dry air near the blowout central axis P. Further, since the hair shaping nozzle 20 and the hair brush 21 can be rotated to hold the position at the user's favorite position, the hair can be effectively dried and curled in a comfortable posture as a whole. Further, since the hair brush 21 is tilted downward and the dry air is blown to the hair captured by the bristle 31, the structure of the hair shaping unit can be simplified and the cost can be reduced as compared with the case where the conversion mechanism 22 is separately provided.

(Example 7) FIG. 14 shows a hair dryer according to the seventh embodiment of the present invention. There, in a state where the hairbrush 21 is switched to the hair shaping posture, the support base 30 is tilted downward toward the base tip side, and the seven rows of bristle 31 on the base tip side intersect with the dry wind blowing central axis P. Is the same as in Example 6. However, the hair styling unit in the seventh embodiment is different from the sixth embodiment in that the hair styling nozzle 20 is omitted and the support shaft 36 of the hair brush 21 is supported by the bracket 83 provided in the main body case 1 so as to be able to reverse and swing. According to such a hair conditioning unit, when the hair is dried while being combed with the hair brush 21, the hair captured by the bristle 31 can be directly blown with a vigorous dry air near the blowout central axis P. Further, the structure of the hairdressing unit can be simplified, the cost can be reduced, and the weight can be reduced by the amount that the hairdressing nozzle 20 is omitted.

(Example 8) FIG. 15 shows a posture detection switch 61 constituting the hair dryer of the present invention. In FIG. 15A, the posture detection switch 61 is composed of a magnet 85 embedded and fixed on the side of the base shaft 29 and a break-shaped reed switch 86 embedded and fixed on the side of the main body case 1, and the hair brush 21 is in a hair shaping posture. In the state of being switched to, the reed body of the reed switch 86 is closed so that the on signal can be output to the control unit 15. In FIG. 15B, the posture detection switch 61 is configured by the switching protrusion 87 provided on the side of the base shaft 29 and the normally closed push button switch 88 provided on the side of the main body case 1, and the hairbrush 21 is in the hair shaping posture. The push button switch 88 can output an on signal to the control unit 15 in the state of being switched to.

(Example 9) FIGS. 16 and 17 show the hair dryer according to the ninth embodiment of the present invention. As shown in FIG. 16, the auxiliary grip 90 has a mounting portion 91 externally fitted to the suction port 4 and a grip shaft portion 92 projecting from the center of the rear surface of the mounting portion 91 along the center axis P for blowing dry air. It consists of a funnel-shaped plastic molded product. Specifically, the grip shaft portion 92 is projected so that its central axis is substantially coaxial with the dry air blowing central axis P, and the dry air blowing central axis P is the center of the tubular main body case 1. It is almost coaxial with the axis. The mounting portion 91 includes a cylinder wall 93 and an end wall 94 that is continuous with the trailing edge of the cylinder wall 93, and has a fan shape that allows the passage of external air through four points in the circumferential direction of the end wall 94 that is in close contact with the suction grill 6 during use. The intake opening 95 is formed. Further, a through hole 96 is formed in the center of the lower surface of the cylinder wall 93. The grip shaft portion 92 is formed of a breathable tubular shaft that communicates with the inside of the mounting portion 91, and an intake port 97 that allows the passage of external air is opened at the tip of the grip shaft portion 92. Engagement ribs 98 that engage with the stepped portion 1a of the main body case 1 are formed at three locations on the inner surface of the opening edge of the cylinder wall 93.

When performing the drying work while combing the hair with the hair brush 21, the main body grip 2 is gripped and held and the main body case 1 is held according to the difference in the length of the hair and the position of the hair to be dried on the head. In many cases, the hair dryer is held while grasping the peripheral surface of the hair. However, in either case, when the hair is curled by rotating the main body case 1 while combing the hair with the hair brush 21, the posture and angle of the hand and arm holding the hair dryer are unnatural. It is easy to become and it is not easy to use. An auxiliary grip 90 is provided in order to eliminate such inconvenience.

In the hair dryer provided with the auxiliary grip 90, as shown in FIG. 16, the mounting portion 91 of the auxiliary grip 90 is mounted on the main body case 1 on the suction port 4 side, and the grip shaft portion 92 is gripped and held with one hand. While combing the hair with the hair brush 21, the main body case 1 is rotated around the central axis P for blowing dry air to curl the hair. As described above, since the grip shaft portion 92 projects along the central axis P for blowing dry air, the hand and wrist on the side holding the grip shaft portion 92 are lightly moved around the forearm shaft. The hair brush 21 can be rotated easily and accurately just by twisting it. Therefore, the work of combing and drying the hair with the hairbrush 21 and the work of squeezing the hair can be effectively performed in a more comfortable posture. Also, during drying work, the position of the hand holding the grip shaft portion 92 and the position of the hair brush 21 that captures the hair are far apart, so the hair combing condition and finish condition can be clearly visually observed before use. It is possible to accurately perform the curl processing intended by the person.

The auxiliary grip 90 also serves as a stand for using the hair dryer in a placed and held state. Therefore, a stand shaft portion 2a having a round shaft cross section is provided at the lower end of the main body grip 2, and the diameter of the stand shaft portion 2a is set to be slightly smaller than the inner surface diameter of the grip shaft portion 92. When the auxiliary grip 90 is used as a stand, as shown in FIG. 17, the auxiliary grip 90 is placed on a table so that the cylinder opening of the mounting portion 91 is supported by the mounting surface, and the power cord 99 is connected. The stand shaft portion 2a is internally fitted and mounted in the intake port 97 of the grip shaft portion 92 in a state of being passed through the inside of the grip shaft portion 92 and the mounting portion 91 and being derived from the through port 96. In this way, according to the usage pattern in which the auxiliary grip 90 is used as a stand for a hair dryer, it is possible to perform hair treatment in a hands-free state while supplying dry air to the hair, so that the hair can be dried and habitual. The usability of the hair dryer can be further improved by diversifying the hair treatment such as attaching.

(Example 10) FIGS. 18 and 19 show the hair dryer according to the tenth embodiment of the present invention. There, the hairdressing unit is composed of a hairdressing nozzle 20 attached to and detached from the accessory mounting portion 8 and a roll brush (hairdressing body) 21 fixed to the center of the outlet 26 of the hairdressing nozzle 20. The hair-dressing nozzle 20 includes a wind guide cylinder portion 101, and a connecting portion 23 that engages with the step portion 24 of the accessory mounting portion 8 is formed at the rear end of the wind guide cylinder portion 101. A connecting boss 103 for fixing the roll brush 21 and a radial support frame 104 are formed on the inner surface of the outlet 102 of the above. The air guide tube portion 101 includes a grip recess 105 continuous with the outlet 5 of the main body case 1 and a bell mouth portion 106 continuous with the grip recess 105, and the bell mouth portion 106 is continuous with the grip recess 105. The diameter is expanded toward the outlet 102 of the air guide tube portion 101. As described above, the roll brush 21 is arranged in the center of the dry air feeding area fed from the outlet 26 of the hair shaping nozzle 20.

The grip recess 105 is formed in a multi-cylindrical shape by an inner wall 108 formed in the shape of an inner concave cylinder and an outer wall 110 fixed to the outside of the inner wall 108 with a heat insulating space 109 interposed therebetween. In this way, when the grip recess 105 is formed in a multiple tubular shape by the inner wall 108 and the outer wall 110, the heat of the inner wall 108 heated by the dry air is conducted to the outer wall 110 when the hair is combed by the roll brush 21. In addition, since heat conduction can be blocked in the heat insulating space 109, it is possible to prevent the outer peripheral surface of the grip recess 105 from becoming hot. Therefore, the hair can be continuously dried, combed, or curled while the grip recess 105 is being gripped. As described above, the outer wall 110 prevents the hand from directly touching the hot inner wall 108, and prevents the heat of the inner wall 108 from being transferred to the fingers.

FIG. 19 shows the details of the relational dimensions between the hair shaping nozzle 20 and the grip recess 105 and the main body case 1. In FIG. 19, when the outer diameter dimension of the suction port 4 of the main body case 1 is A1 and the outer diameter dimension of the outlet 5 is B1, the grip recess 105 is inside in a region smaller than the outer diameter dimension B1 of the outlet 5. It is formed in a dent shape. According to such a hair shaping nozzle 20, since the diameter of the inner recess of the grip recess 105 can be reduced, even a user with a small hand and short fingers can perform hair treatment while firmly gripping and holding the grip recess 105. ..

The hair wrapped around 30 can be heated or cooled from the inside.

As described above, if the roll brush 21 is arranged in the center of the outlet 26 of the hair styling nozzle 20, high temperature warm air is supplied to the hair captured by the roll brush 21 and there is a risk of damaging the hair. There is. In order to prevent such damage to the hair, a detachment detection switch 113 is arranged on the peripheral wall of the accessory mounting portion 8 of the main body case 1 so that it can be confirmed whether or not the hair shaping unit is mounted on the air outlet 5. .. Then, in the state where the attachment / detachment detection switch 113 detects that the hair conditioning unit is attached to the outlet 5, the control unit 15 reduces the heat generation amount of the heater 13 or increases the drive rotation speed of the motor 12. It is now possible to eliminate the supply of hot air. According to such a hair dryer, even if the hair trimming body 21 is provided at the outlet 102 of the air guide tube portion 101 to which a strong flow of dry air is fed, the hair is fed to the hair captured by the hair trimming body 21. The temperature of the dry air can be lowered to prevent the hair from being damaged and damaged.

(Example 11) FIG. 20 shows a hair dryer according to the eleventh embodiment of the present invention. The hair styling unit and the hair dryer of the eleventh embodiment are the same as the hair styling unit and the hair dryer described in the tenth embodiment, but when the hair styling unit is used, the main body grip 2 is folded up into the second storage posture, and the suction port is further formed. Hair treatment is performed with the auxiliary grip 90 attached to 4. In that case, as shown in FIG. 20, the grip detection switch 114 is arranged in one of the moderation recesses 18 of the main body case 1, and the grip detection switch 114 indicates that the main body grip 2 is switched to the second storage posture. It is possible to detect it. Then, in a state where the grip detection switch 114 detects that the main body grip 2 has switched to the second use posture, the control unit 15 reduces the heat generation amount of the heater 13 or increases the drive rotation speed of the motor 12. , Made it possible to eliminate the supply of hot air. According to such a hair dryer, even if the hair trimming body 21 is provided at the outlet 102 of the air guide tube portion 101 to which a strong flow of dry air is fed, the hair is fed to the hair captured by the hair trimming body 21. The temperature of the dry air can be lowered to prevent the hair from being damaged and damaged. In the hair dryer according to the eleventh embodiment, it is not necessary to perform the hair treatment with the auxiliary grip 90 attached to the suction port 4, and the peripheral wall of the main body case 1 and the grip recess 105 of the air guide tube portion 101 are gripped. Hair treatment can be performed in the state of being. When the hair treatment is performed while the grip recess 105 is gripped, the main body grip 2 can be in the second storage posture, so that the main body grip 2 can be prevented from getting in the way.
