BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, embodiments of the present invention will be described with reference to the drawings. In the following description, the same parts are given the same reference numerals. Their names and functions are also the same. Therefore, detailed description thereof will not be repeated.

<First Embodiment>
In this embodiment, a hair dryer 1 having a blowing structure of one example of the present invention will be described as an example.

(Overall Configuration of Hair Dryer 1)
First, the overall configuration of a hair dryer 1 according to this embodiment will be described with reference to FIGS. 1 and 2. FIG. FIG. 1 is a perspective view of a hair dryer 1. FIG. FIG. 2 is a plan view showing the appearance of the hair dryer 1 when viewed from the front (air outlet side).

As shown in FIG. 1, the hair dryer 1 is mainly composed of a body portion 10 and a grip portion 20. As shown in FIG. The body part 10 has an air blowing mechanism inside, and blows out the air sucked from the suction port 12 from the blowing ports 11 (11a and 11b).

The grip portion 20 is positioned below the body portion 10 . The grip part 20 is a part that a user holds when using the hair dryer 1 . The grip portion 20 is provided with an operation portion 76 (see FIG. 3). When the hair dryer 1 is used, the operation of the hair dryer 1 is started or stopped by the user operating the operation unit 76 . Further, by operating the operation unit 76, the type of air (warm air/cold air) and the amount of air blown out from the outlet 11 are adjusted. Note that some of the operation units may be provided in the main body.

Although not shown, a power cord is attached below the grip portion 20 . It should be noted that, in another aspect of the present invention, the hair dryer 1 may be of a cordless type. In this case, for example, a primary battery or a secondary battery is provided inside the grip portion 20 .

In this specification, in describing the shape and positional relationship of each component of the hair dryer 1, for the sake of convenience, the hair dryer 1 is shown in FIGS. It is defined by three coordinate axes of the (Y1-Y2) direction (vertical direction) and the Z (Z1-Z2) direction (front-rear direction).

The body portion 10 has a substantially rectangular parallelepiped outer shape. The Z1 side of the body portion 10 constitutes a front surface 10a (the surface on which the outlet 11 is arranged). An air outlet 11 is arranged on the front surface 10a. The air outlet 11 is composed of two outlets, a first outlet 11a and a second outlet 11b. The Z2 side of the body portion 10 constitutes a rear surface 10b. An air suction port 12 is arranged on the rear surface 10b.

As shown in FIG. 2, the outlets 11a and 11b are arranged at either the left or right end of the front surface 10a of the main body 10. As shown in FIG. Specifically, the first outlet 11a is arranged along the left (X1 side) end of the front surface 10a when viewed from the front. The second outlet 11b is arranged along the right (X2 side) edge of the front surface 10a when viewed from the front.

Each of the outlets 11a and 11b has an elongated (vertically elongated) opening in the vertical direction (Y direction). Also, the opening of the first outlet 11a and the opening of the second outlet 11b are arranged substantially parallel to each other. Since the openings of the air outlets 11a and 11b have such a shape, when the hair is dried using the hair dryer 1, the longitudinal direction of each opening extends in the direction along the direction of extension of the hair at the treatment site. can be oriented.

On the front surface 10a of the main body 10, no outlet is provided between the first outlet 11a and the second outlet 11b, and the front surface 10a has a flat shape.

Since the hair dryer 1 has the outlet 11 having the shape described above, the front face 10a of the main body 10 blows air forward (Z1 direction) from both ends in the width direction (X direction). A turbulent flow can be generated in front of the central portion of the front face 10a at the location of the blowout and treatment site.

Here, "a turbulent flow is occurring" means that an air flow having an air flow other than the forward air flow from the front surface 10a (the air flow in the Z1 direction) is generated. do. For example, a state in which hair is curled up at a treatment site can be referred to as a state in which turbulence is occurring. In addition, the above-mentioned "position to be treated" can also be rephrased as a position away from the front surface 10a by the assumed use distance L of the hair dryer 1. FIG.

Next, the internal configuration of the hair dryer 1 will be described. FIG. 3 shows the internal configuration of the hair dryer 1. As shown in FIG. Inside the hair dryer 1, there are provided a control section 71, a fan 72, a heater 73, an ion supply section (also referred to as a charged fine particle generator) 74, an air passage (not shown), an operation section 76, and the like.

The control unit 71 controls operations of the fan 72 , the heater 73 , the ion supply unit 74 , etc. according to the content of the operation performed by the operation unit 76 .

The fan 72 has a motor inside. When the hair dryer 1 is in operation, the fan 72 is rotated by the driving force of the motor. As a result, an air flow from the inlet 12 to the outlet 11 is formed in the air passage in the main body 10 .

The heater 73 heats the air taken into the air passage from the suction port 12 . When the hair dryer 1 is in operation, the heater 73 is in operation, so that the air taken into the blowing path is heated, and hot air can be sent out from the blowout port 11 . The controller 71 controls ON/OFF of the heater 73 . For example, when the user selects the cold air blowing operation mode using the operation unit 76 , the control unit 71 stops the operation of the heater 73 . As a result, cool air is sent out from the outlet 11 . Further, the control unit 71 may control the heater 73 so that hot air and cold air are alternately blown from the outlet 11 .

The ion supply unit 74 is arranged near the blowout port 11 .

The ion supply unit 74 supplies positive (+) ions (eg, H ⁺ (H ₂ O) _m (m is an arbitrary natural number)) and negative (−) ions (eg, O ₂ ⁻ (H ₂ O) _n (n generates at least one of any natural number)). Since the hair dryer 1 is provided with the ion supply unit 74 , the air blown from the blowing port 11 can contain ions. Since the air blown from the outlet 11 contains ions, it is possible to prepare the scalp environment such as keeping the scalp to be treated moist. In addition, it keeps the moisture of the hair to be treated, tightens the cuticle, suppresses damage to the hair, and provides a treatment effect. Note that the hair dryer according to another aspect of the present invention may have a configuration in which the ion supply unit is not provided.

The operation unit 76 is operated by the user. Operation information in the operation unit 76 is transmitted to the control unit 71 .

With the configuration described above, when the hair dryer 1 is operated, air is blown out from the outlet 11 . The air blown out from the outlet 11 is guided to the user's treatment site and its vicinity. This allows the hair to be dried.

Here, the treated area means a portion of the user's head (more specifically, hair) that is intensively dried using the hair dryer 1 . For example, the portion facing the front surface 10a of the main body 10 when using the hair dryer 1 corresponds to the treated portion. When using the hair dryer 1, the user dries the hair while moving the hair dryer 1 with respect to the hair. Therefore, the treatment site moves sequentially.

(Regarding the wind blowing out from the outlet)
Next, the flow of air blown out from the outlet 11 of the hair dryer 1 will be described with reference to the drawings. A method of drying hair using the hair dryer 1 is also described.

FIG. 4 is a plan view of the hair dryer 1 viewed from above (that is, viewed from the Y1 side to the Y2 side). FIG. 4 shows the arrangement positions of the first outlet 11a and the second outlet 11b provided on the front surface 10a of the main body 10. As shown in FIG. FIG. 5 schematically shows the wind speed distribution at the treatment site when hair is dried using the hair dryer 1. As shown in FIG. FIG. 6 schematically shows the flow of air at the treatment site when hair is dried using the hair dryer 1. As shown in FIG.

As shown in FIG. 4, the blowout surfaces of the two blowout openings 11a and 11b provided in the hair dryer 1 are arranged along the front surface 10a of the main body 10 so as to be substantially flush with each other. Therefore, air is blown out from the outlets 11a and 11b in a direction (Z1 direction) substantially perpendicular to the front surface 10a. As described above, the first outlet 11a and the second outlet 11b have a vertically long shape in the vertical direction (Y direction). Therefore, from the first outlet 11a and the second outlet 11b, winds that are relatively converged in the width direction (X direction) are blown forward.

The wind blown out from the first outlet 11a and the second outlet 11b has a velocity distribution as shown in FIG. Here, the assumed use distance L is the position of the air outlet 11 assumed when the hair dryer 1 is used for drying hair (that is, the front surface 10a) from the treatment site (user's head (specifically, the user's head)). means the distance to the hair or scalp)). More specifically, the assumed use distance L can be in the range of 5 cm or more and 30 cm or less, preferably in the range of 10 cm or more and 20 cm or less.

Within the range of the assumed use distance L, the speed of the wind blown from each of the outlets 11a and 11b is higher than the speed of the wind at the position in front of the first outlet 11a and the position in front of the second outlet 11b. , the wind velocity at the center position of each front position is low. FIG. 5 schematically shows a high wind speed region and a low wind speed region at the front position of the front surface 10a of the hair dryer 1. As shown in FIG. In addition, in FIG. 5, the wind speed distribution in the assumed use distance L of the hair dryer 1 (that is, in the vicinity of the user's head) is shown by the curved line shape of the dashed line. The further to the left the dashed line is, the higher the speed.

In addition, the first outlet 11a and the second outlet 11b are preferably separated by a distance of 2 cm or more and 15 cm or less, and the distance is 4 cm or more and 10 cm or less. preferably spaced apart. This configuration makes it easier to generate turbulence at a position between the front position of the first outlet 11a and the front position of the second outlet 11b.

Since the hair dryer 1 has the air blowing structure as described above, the position (that is, the user's head) is separated from the front surface 10a where the blowing outlets 11a and 11b are arranged by the assumed use distance L of the hair dryer 1. ), turbulence can be generated by the wind blown from each outlet at a position between the respective front positions of the outlets 11a and 11b. In FIG. 6, between the front position of the first outlet 11a and the front position of the second outlet 11b, the wind blown from each outlet 11a and 11b blows out from each outlet 11a and 11b. It shows how turbulence occurs between the winds. That is, it shows how turbulence is generated between the front position of the first outlet 11a and the front position of the second outlet 11b at a position separated by the assumed use distance L from the outlet of the hair dryer. ing.

When the hair is dried using the hair dryer 1, such turbulent flow is generated at the treatment site, causing the hair at the treatment site to be curled up and spread away from the scalp. As a result, the hair, which tends to get wet and tend to be bundled, can be separated individually, and the wind can be applied to the hair. Therefore, it becomes possible to dry wet hair efficiently in a shorter time.

When the hair is dried using the hair dryer 1, the front surface 10a of the main body 10 is dried so that the vertical direction (Y direction) of the hair dryer 1 is aligned with the extension direction of the hair at the treatment site to be dried. It is preferable to make them face each other. By using the hair dryer 1 in this manner, the longitudinal direction of each of the vertically elongated outlets 11a and 11b can be aligned with the hair extension direction. This makes it easier to disperse each of the hairs that tend to get wet and clump together, and the wet hair can be dried more efficiently.

(Example)
Below, the result of measuring the wind speed difference between each position of the treatment site (hair) using the hair dryer 1 is shown. The results of observing the magnitude of the wind speed difference and the occurrence of turbulence are also shown.

FIG. 9 schematically shows the positional relationship between the hair dryer 1 used in this embodiment and the head of a mannequin to be treated. The power consumption of the hair dryer 1 was 1200 watts (W). Moreover, the distance between each of the outlets 11a and 11b was set to Y=6 cm. Also, the assumed use distance L was set to X=5 to 30 cm. In addition, dry hair of a mannequin was used as an object to be treated.

In this embodiment, the wind speed at the front position of the outlet (high wind speed region) (positions A and C in FIG. 9) and the intermediate position (low wind speed region) of each outlet (position B in FIG. 9) We observed the turbulent flow by changing the difference from the wind speed. The results are shown in Table 1. As shown in Table 1, the occurrence of turbulence at each speed difference was evaluated on a three-grade scale of 0 (good occurrence), Δ (occurrence to some extent), and × (weak occurrence). If the generation of turbulent flow is weak (corresponding to x in Table 1), the hair drying time will not be shortened much.

From the results shown in Table 1, if the wind speed difference between the high wind speed region (position A or position C) and the low wind speed region (position B) is 4.4 m / s or more, it corresponds to the low wind speed region (position B). It was confirmed that the hair was raised and the drying speed was improved.

If the wind speed difference between the high wind speed region and the low wind speed region is 4.4 m/s and 4.5 m/s, the hair at positions A and C shown in FIG. The hair of B is less recessed on the head side than the positions A and C due to the low wind speed. In this way, a turbulent flow was generated at position B between position A and position C, and the hair at position B could be lifted. That is, when the assumed use distance L is in the range of 5 cm or more and 30 cm or less, the wind speed difference between the high wind speed region and the low wind speed region is set to 4.0 m / s or more, so that turbulence is generated at position B. can be made By increasing the wind speed difference between the high wind speed region and the low wind speed region (for example, about 8.0 m/s or more), the effect of generating turbulence is increased, and the hair drying time can be further shortened.

By setting the assumed use distance L within the range of 10 cm or more and 20 cm or less, turbulence can be generated even when the wind speed difference between the high wind speed region and the low wind speed region is small.

(Summary of the first embodiment)
A hair dryer 1 according to the present embodiment has an air blowing structure. The blowout structure includes a first blowout port 11a and a second blowout port 11b spaced apart from the first blowout port 11a. This blow-out structure is arranged such that the first blow-out opening 11a and the second blow-out opening 11b are arranged at a position (for example, the position of the treatment site) separated by the assumed use distance L of the hair dryer from the arrangement surface (that is, the front surface 10a). A turbulent flow is generated between the front position of the second outlet 11a and the front position of the second outlet 11b.

According to this configuration, when the hair dryer 1 is used to dry the hair, a turbulent flow is generated at the location to be treated, causing the hair at the location to be treated to be curled up and spread away from the scalp. As a result, the hair, which tends to get wet and tend to be bundled, can be separated individually, and the wind can be applied to the hair. Therefore, it becomes possible to dry wet hair efficiently in a shorter time.

Since the hair dryer 1 has such a blowing structure, it is more convenient for the user to dry his/her own hair.

In the above-described embodiment, the configuration in which the body portion 10 of the hair dryer 1 has two outlets (that is, the first outlet 11a and the second outlet 11b) has been described as an example. However, in another example of the present invention, an attachment (blowing structure) having two outlets (e.g., a first outlet 11a and a second outlet 11b) is attached to the front of the main body of the hair dryer. It may be a mode that it is used as

Moreover, in the embodiment described above, an example in which each of the outlets 11a and 11b has a vertically long shape has been described. However, in another configuration example, each outlet may have a shape such as a circular shape in which the length in the X direction and the length in the Y direction are substantially the same, instead of the vertically long shape. In this case, the separation distance between the first outlet and the second outlet may be found by experimentation, taking into consideration the assumed usage distance and finding the distance suitable for the shape of the outlet. Thereby, a turbulent flow can be generated between the front positions of each outlet.

<Second embodiment>
Next, a second embodiment of the invention will be described. The second embodiment differs from the first embodiment in the configuration of the outlet. As for the rest of the configuration, substantially the same configuration as in the first embodiment can be applied. Therefore, the following description will focus on the configuration different from that of the first embodiment.

FIG. 7 shows a hair dryer 101 according to a second embodiment. FIG. 7 is a view of the hair dryer 101 viewed from above (that is, viewed from the Y1 side to the Y2 side).

A hair dryer 101 according to the second embodiment mainly includes a body portion 110 and a grip portion 20 . The body part 110 has an air blowing mechanism inside, and blows out the air sucked from the suction port 12 from each of the blowing ports 111a and 111b.

As for the internal configuration of the body portion 110, substantially the same configuration as the internal configuration of the body portion 10 described in the first embodiment can be applied. Moreover, as for the configuration of the grip portion 20, the same configuration as the configuration of the grip portion 20 described in the first embodiment can be applied. Therefore, detailed description is omitted.

The body portion 110 has a substantially rectangular parallelepiped outer shape. The Z1 side of the body portion 110 constitutes a front surface 110a (the surface on which the outlets 111a and 111b are arranged). An air outlet is arranged on the front surface 110a. The air outlet is composed of two outlets, a first outlet 111a and a second outlet 111b. The Z2 side of the body portion 110 constitutes the rear surface. An air suction port 12 is arranged on the rear surface.

Each of the outlets 111a and 111b has an elongated (longitudinally elongated) opening in the vertical direction (Y direction). As in the first embodiment, the first outlet 111a is arranged along the left (X1 side) edge of the front surface 110a when viewed from the front. The second outlet 111b is arranged along the right (X2 side) edge of the front surface 110a when viewed from the front.

As a result, when the front face 110a is viewed from the front, the first outlet 111a and the second outlet 111b are substantially parallel to each other. Since each of the outlets 111a and 111b has such a shape, when the hair is dried using the hair dryer 101, the longitudinal direction of each of the outlets 111a and 111b is parallel to the direction of the hair at the treatment site. can be matched.

In the hair dryer 1 according to the first embodiment, the blowout surfaces of the first blowout port 11a and the second blowout port 11b are arranged so as to be substantially flush along the front surface 10a of the main body 10. . On the other hand, in the hair dryer 101 according to the present embodiment, the blowout surfaces of the first blowout port 111a and the second blowout port 111b are both configured to blow air slightly inward. That is, the first air outlet 111a arranged at the left end of the main body 110 when viewed from the front has an air blowing direction that is slightly tilted to the right from the front. In addition, the second air outlet 111b arranged at the right end of the main body 110 when viewed from the front has an air blowing direction that is slightly tilted leftward from the front.

As a result, as shown in FIG. 7, the air blown out from each of the outlets 111a and 111b is directed to the central portion in the width direction (X direction) on the front side of the front surface 110a. With this configuration, it is possible to suppress the outward diffusion of the air blown out from the outlets 111a and 111b. Therefore, loss of air volume can be reduced.

In addition, the inclination angle of each of the outlets 111a and 111b with respect to the front surface 110a is determined by the wind blown from each outlet at a position between the front positions of the outlets 111a and 111b at a position separated by the assumed use distance L. It is preferable to set it to the extent that turbulence can be generated. Further, the distance between the first outlet 111a and the second outlet 111b is the same as the distance described in the first embodiment so that turbulence can be generated by the wind blown out from each outlet. (for example, a distance of 2 cm or more and 15 cm or less).

<Third Embodiment>
Next, a third embodiment of the invention will be described. The third embodiment differs from the first embodiment in the configuration of the outlet. As for the rest of the configuration, substantially the same configuration as in the first embodiment can be applied. Therefore, the following description will focus on the configuration different from that of the first embodiment.

FIG. 8 shows a hair dryer 201 according to a third embodiment. FIG. 8 is a plan view showing the configuration of the hair dryer 201 when viewed from the front (air outlet side).

A hair dryer 201 according to the third embodiment mainly includes a body portion 210 and a grip portion 20 . The body part 210 has an air blowing mechanism inside, and blows out the air sucked from the suction port 12 from each of the blowing ports 211a and 211b.

As for the internal configuration of the body portion 210, substantially the same configuration as the internal configuration of the body portion 10 described in the first embodiment can be applied. Moreover, as for the configuration of the grip portion 20, the same configuration as the configuration of the grip portion 20 described in the first embodiment can be applied. Therefore, detailed description is omitted.

The body portion 210 has a substantially rectangular parallelepiped outer shape. The Z1 side of the body portion 210 constitutes a front surface 210a (the surface on which the outlets 211a and 211b are arranged). An air outlet is arranged on the front surface 210a. The air outlet is composed of two outlets, a first outlet 211a and a second outlet 211b. The Z2 side of the body portion 210 constitutes the rear surface. An air suction port 12 is arranged on the rear surface.

Further, in this embodiment, as shown in FIG. 8, the blowing surface of the first blowing port 211a has a plurality of openings 213. As shown in FIG. Similarly, the blowing surface of the second blowing port 211b has a plurality of openings 213. As shown in FIG. FIG. 8 shows an example in which the first outlet 211a and the second outlet 211b each have six openings, but the number of openings is not limited to five. Also, in FIG. 8, the shape of the opening 213 is substantially circular, but the shape of the opening is not limited to circular.

In this manner, the blowout surfaces of the blowout ports 211a and 211b provided in the main body 210 may be divided into a plurality of parts.
