(About the blower)
Subsequently, a more specific configuration of the blower unit 150 will be described with reference to FIGS. 6 and 7. 6 and 7 show the internal configuration of the hair dryer 10. FIG. 6 is a diagram showing the inside of the main body 11 in a state where the upper portion of the main body 11 is cut along the XX plane. FIG. 7 is a cross-sectional view showing the internal configuration of the main body 11 in a state where the main body 11 is cut in the vertical direction (Y direction) at the center position in the left-right direction (X direction). In FIGS. 6 and 7, the flow of wind generated by the blower unit 150 is indicated by an arrow. In FIG. 6, the heater 191 is not shown.

As described above, the blower portion 150 is mainly composed of a centrifugal fan 151, a motor 153, a motor fixing component 152, and the like.

The centrifugal fan 151 has a plurality of moving blades (also referred to as rotary blades) 151a. The centrifugal fan 151 is connected to the rotation shaft 153a of the motor 153, and is driven by the motor 153 to rotate. As the moving blades 151a rotate, the air flowing into the main body 11 from the suction port 23 is discharged in the centrifugal direction of the rotating shaft 153a. As a result, a wind in the direction indicated by the arrow in FIG. 7 is generated.

The motor 153 is arranged on the front side (Z1 side) of the centrifugal fan 151. The motor 153 has a rotation shaft 153a that projects to the rear side (Z2 side). The end of the rotating shaft 153a projecting rearward is connected to the centrifugal fan 151.

The motor 153 is located at a position that at least partially overlaps the air passages (specifically, the first air passage FA and the second air passage FB, etc.) that connect the air blowers 150 to the outlets 12a and 12b in a side view. Is located in. As shown in FIG. 7 and the like, in the hair dryer 10 according to the present embodiment, more than 1/2 of the length of the main body portion of the motor 153 excluding the rotation shaft 153a in the Z direction is the first ventilation path FA and the side view. It overlaps with the second ventilation path FB. As a result, the dimension of the main body 11 in the Z direction can be reduced (shortened) while ensuring the length of the blowing path from the blowing portion 150 to the outlets 12a and 12b.

The motor fixing component 152 is arranged between the centrifugal fan 151 and the motor 153. The motor fixing component 152 has a plurality of stationary blades (also referred to as fixed blades) 152a and a motor accommodating portion 152b. The main body portion of the motor 153 is fitted into the motor accommodating portion 152b. As a result, the motor 153 is fixed to the motor accommodating portion 152b.

A plurality of stationary blades 152a are provided along the outer circumference of the motor accommodating portion 152b. The stationary blades 152a are arranged so as to have a predetermined distance from each other. As a result, the wind generated by the rotation of the centrifugal fan 151 passes between the stationary blades 152a, and the air passage on the front side (specifically, the first air passage FA and the second air passage FB, etc.). (See FIG. 6). As described above, the motor fixing component 152 is provided with the ventilation path F2 connected to the ventilation path.

(Structure of ventilation path)
Subsequently, the distribution path (blower path) in the main body 11 of the wind generated in the blower 150 will be described. In the hair dryer 10 according to the present embodiment, the wind generated in the blower portion 150 passes through the space formed by the air passage forming member 3 and the heater support member 160, and most of them pass through the first outlet 12a and the first outlet 12a. It is blown out from the outlet 12b of 2. That is, the air passage is mainly formed by the air passage forming member 3 and the heater support member 160.

The wind generated in the blower unit 150 by the rotation of the centrifugal fan 151 is discharged in the centrifugal direction as shown by an arrow in FIG. The space provided with the moving blades 151a of the centrifugal fan 151 is referred to as a wind generating portion F1. As shown by the solid arrow in FIG. 6, the wind generated by the wind generating portion F1 passes between the stationary blades 152a of the motor fixing component 152 provided on the front side of the centrifugal fan 151, and is in front of the stationary blades 152a. It flows to the ventilation path on the side. As described above, the portion of the motor fixing component 152 where the stationary blade 152a is arranged is the ventilation path F2 connected to the ventilation path. The ventilation passage F2 can also be said to be the outlet of the wind in the blower unit 150.

The wind that has passed through the ventilation passage F2 flows into the space formed by the air passage forming member 3, the heater support member 160, and the like. This space is mainly divided into three spaces by the first air passage dividing portion 171 and the two second air passage dividing portions 173 attached to the outer surface of the heater support member 160. Each of the divided spaces serves as a ventilation path. In this way, three air passages, a first air passage FA, a second air passage FB, and a third air passage FC, are formed in the main body 11.

As shown in FIG. 6, the first air passage path FA is connected to the first outlet 12a. A part of the wind that has exited the ventilation path F2 of the ventilation unit 150 passes through the first ventilation path FA and is blown out from the first outlet 12a as shown by the broken line arrow in FIG.

Further, as shown in FIG. 6, the second ventilation path FB is connected to the second outlet 12b. A part of the wind that has exited the ventilation path F2 of the ventilation unit 150 passes through the second ventilation path FB and is blown out from the second outlet 12b as shown by the arrow of the alternate long and short dash line in FIG.

As shown in FIG. 6, the standing position of the first air passage dividing portion 171 is substantially overlapped with one front end of the stationary blade 152a provided on the motor fixing component 152 in the front view. As a result, the wind that has exited the blower section 150 is divided into a wind that flows into the first blower path FA side and a wind that flows into the second blower path FB side on the most upstream side of the blower path. That is, at positions separated from the first outlet 12a and the second outlet 12b by a predetermined distance, the air passage to the first outlet 12a (that is, the first air passage FA) and the second outlet A blow path to the port 12b (that is, a second blow path FB) is formed.

As described above, in the hair dryer 10, the air passage is divided into two or more at the front end of the air passage F2 which is the outlet of the wind in the air blower 150 (that is, the most upstream side of the wind flow in the air passage). Has been done. Then, one of the divided air passages (for example, the first air passage FA) is connected to the first outlet 12a, and the other of the divided air passages (for example, the second air passage FB). Is connected to the second outlet 12b. According to this configuration, the length of each air blowing path connected to each outlet can be increased in the front-rear direction while suppressing the increase in the dimension of the main body 11 in the front-rear direction (Z direction) (the length becomes long). Can be secured. By ensuring the dimensions (length in the front-rear direction) of each air flow path connected to each air outlet at a predetermined value or more, it is possible to suppress the bias of the air volume sent from each air outlet.

As shown in FIG. 8 and the like, a slight gap G may be provided between the rear side end portion of the first air passage dividing portion 171 and the front side end portion of the stationary blade 152a.

Further, as shown in FIG. 8 and the like, the inside of the second ventilation path FB is divided into a plurality of parts by a substantially plate-shaped partition member 172 extending in the Z direction. Similarly, the inside of the first air passage FA is also divided into a plurality of parts by a substantially plate-shaped partition member 172 extending in the Z direction. In this way, the inside of each of the blower paths FA and FB is divided into a plurality of spaces along the direction of the main wind flow (that is, the Z1 direction), so that the wind from the blower portion 150 is blown out from the outlet 12a. And can be rectified towards 12b.

The third ventilation path FC is located on the lower side (that is, the grip portion 20 side) of the main body portion 11. A part of the wind that has left the ventilation path F2 of the ventilation section 150 also flows into the third ventilation path FC. The front side (Z1 side) of the third air passage FC is blocked by the wall portion of the air passage forming member 3. That is, when the hair dryer 10 is viewed from the front surface portion 11a side of the main body portion 11, the third blower path FC does not overlap with the first outlet 12a and the second outlet 12b.

As shown in FIG. 7, an electronic component 192 is arranged in the third ventilation path FC. The heater control component (for example, a triac) included in the electronic component 192 generates heat during the operation of the heater 191 and the temperature rises. By arranging the electronic component 192 including such a heater control component in the third ventilation path FC, the air from the blower unit 150 can be sent around the electronic component 192. As a result, heat dissipation of the electronic component 192 can be promoted, and a temperature rise of the electronic component 192 can be suppressed.

(Composition around the heater)
Subsequently, the configuration of the heater 191 arranged in the ventilation path will be described with reference to FIG. FIG. 8 shows the configuration in the second ventilation path FB. The hair dryer 10 shown in FIG. 8 shows a state in which the right side surface member 2b and the air passage forming member 3 are removed. The inside of the first air passage FA has a configuration symmetrical to that of the second air passage FB.

As shown in FIG. 8, the heater 191 is composed of a plurality of coiled heating wires. Each heating wire constituting the heater 191 is arranged so as to penetrate each partition member 172 and cross the inside of the second ventilation path FB. Although not shown in FIG. 8, each heating wire constituting the heater 191 is arranged so as to pass through the first air passage dividing portion 171 and cross the inside of the first air passage FA. The heater 191 extends from one second air passage dividing portion 173 to the other second air passage dividing portion 173 along the outer circumference of the heater support member 160.

As described above, the heater 191 is supported by the first air passage dividing portion 171, the partition member 172, and the second air passage dividing portion 173, and is arranged in the first air passage path FA and the second air passage path FB. ing. Further, the heater 191 is not provided in the third air passage FC. As a result, the inside of the first air passage FA and the second air passage FB is heated by the heater 191 so that warm air can be blown out from the outlets 12a and 12b.

On the other hand, the third air passage FC is not directly heated by the heater 191. Therefore, it is possible to suppress the temperature rise in the third air passage FC when the heater 191 is turned on. As described above, the electronic component 192, which is a component to be cooled, is arranged in the third air passage FC. Even when the warm air is blown out, the air sent from the blower unit 150 into the third blower path FC is not directly heated by the heater 191. Therefore, the temperature rise of the electronic component 192 arranged in the third blower path FC is suppressed. be able to.

The operation mode display unit 31 is a display unit for displaying various operation modes of the hair dryer 10, such as a normal mode, a quick-drying mode, a styling mode, and a hair care mode (ion blowing mode). In the present embodiment, the operation mode display unit 31 is composed of four LED lamps 31a to 31d (see FIG. 2).

As shown in FIG. 2, a plurality of LED lamps 31a, 31b, 31c, and 31d constituting the operation mode display unit 31 are arranged side by side in the vertical direction (Y direction) below the front surface portion 11a. When the user of the hair dryer 10 operates the operation button 41 (specifically, the operation button 41a (see FIG. 9)) of the operation unit 40, the operation mode of the hair dryer 10 is switched. Then, among the plurality of LED lamps 31a, 31b, 31c, and 31d, the LED lamp corresponding to the selected current operation mode is turned on.

In one example, when the operation mode of the hair dryer 10 is the normal mode, only the top LED lamp 31a is lit. Further, when the operation mode of the hair dryer 10 is the quick-drying mode, only the second LED lamp 31b from the top is lit. Further, when the operation mode of the hair dryer 10 is the styling mode, only the third LED lamp 31c from the top is lit. Further, when the operation mode of the hair dryer 10 is the hair care mode, only the lowermost LED lamp 31d is lit.

The plurality of LED lamps 31a, 31b, 31c, and 31d constituting the operation mode display unit 31 are located in the left-right direction (X direction) of the front portion 11a located between the first outlet 12a and the second outlet 12b. They are arranged vertically in the center of the. Further, the LED lamps 31a, 31b, 31c, and 31d are arranged at a portion extending the center line passing through substantially the center of the front portion 20a. This makes it easier for the user to confirm which of the plurality of LED lamps 31a, 31b, 31c, and 31d is lit. Therefore, the user who is using the hair dryer 10 can easily confirm the current operation mode.

The temperature display unit 32 indicates the temperature of the wind blown out from the outlet 12, such as hot air / cold air. In the present embodiment, the temperature display unit 32 is provided in an annular shape on the outer circumference of the central portion 15. The temperature display unit 32 displays the temperature of the wind by color, for example. Specifically, when warm air is blown out, the temperature display unit 32 turns red, and when cold air is blown out, the temperature display unit 32 turns blue.

In this case, the temperature display unit 32 is composed of a red LED lamp, a blue LED lamp, a light guide member, and the like. The light guide member has an annular shape and is arranged so as to surround the outer periphery of the central portion 15. The red LED lamp and the blue LED lamp are arranged on the rear side of the light guide member. Then, when warm air is blown out from the outlet 12, the red LED lamp lights up, and the red light is diffused by the light guide member to develop an annular color. Further, when cold air is blown out from the outlet 12, the blue LED lamp lights up, and the blue light is diffused by the light guide member to develop an annular color. Thereby, the user can easily identify whether the blown air is hot air or cold air.

As in the hair dryer 10 according to the present embodiment, the display unit 30 is arranged on the same side as the side where the wind outlet 12 is arranged, so that the user can apply the hair dryer 10 to the treatment site (that is, that is). The information on the display unit 30 can be confirmed by directing the line of sight to the outlet 12 side while maintaining the posture toward the hair). Further, when the outlet 12 of the hair dryer 10 is not facing the treatment site, the outlet 12 faces upward when the user reads the information of the display unit 30. That is, when the user reads the information on the display unit 30, the outlet 12 does not face downward. Therefore, it is possible to reduce the possibility that the article placed on the wash basin is blown off by the wind from the hair dryer 10 when it is used toward the mirror on the wash basin or the like.

Further, an operation unit 40 is provided on the same side as the display unit 30 (that is, the front surface portion 20a located on the same side as the front surface portion 11a). As a result, the user can operate each operation button 41 while looking at the operation unit 40, and can also confirm the display content on the display unit 30 arranged on the same side.

In addition to the display unit 30, the hair dryer 10 according to the present embodiment is provided with another display unit (that is, an air volume display unit 43). The air volume display unit 43 is provided on the grip unit 20 as described later.

(About the operation unit)
Subsequently, a more specific configuration of the operation unit 40 will be described. FIG. 9 shows an example of the configuration of the operation unit 40 and the air volume display unit 43. FIG. 10 schematically shows the relationship between the pressing direction of the operation button 41 and the blowing direction of the wind.

The operation unit 40 has a plurality of operation buttons 41 and one power switch 42. The operation button 41 and the power switch 42 constituting the operation unit 40 are mounted on one operation unit forming member 140.

In the example shown in FIG. 9, the operation button 41 is composed of three operation buttons 41a, 41b, and 41c. Each of these operation buttons 41 (41a, 41b, 41c) is arranged on an inclined surface 20b located between the front portion 11a of the main body portion 11 and the front portion 20a of the grip portion 20.

The operation button 41a is a button (operation mode switching button) for switching the operation mode. The operation button 41b is a button (air volume switching button) for switching the air volume. The operation button 41c is a button (air temperature switching button) for switching the air temperature (that is, hot air / cold air). When the power switch 42 is in the ON state (that is, during operation), each of these operation buttons 41 (41a, 41b, 41c) is operated to change the operation setting. In other words, the operation button 41 is a button for changing settings (operation mode, wind temperature, etc.) during operation of the hair dryer 10. Here, the operation of the hair dryer 10 can be rephrased as the operation of the wind blowing or the centrifugal fan 151.

The configuration of each operation button 41 is an example, and the present invention is not limited to this configuration. The button most frequently operated may be arranged at the position of the operation button 41a. This is because the operation button 41a is located near the thumb of the user's right hand when the user grips the hair dryer. The operation buttons 41a, 41b, and 41c are cyclic to switch the mode, air volume, and air temperature.

As shown in FIG. 10, the surface (pressing surface) of each operation button 41 arranged on the inclined surface 20b is inclined along the shape of the inclined surface 20b. That is, the surface of each operation button 41 is substantially flush with the inclined surface 20b. As a result, when the hair dryer 10 is viewed from the side surface or the like, the operation button 41 becomes inconspicuous, and the design of the hair dryer 10 is improved.

For example, each operation button 41 may be a protrusion having a concave curved surface (pressing surface). As a result, the pressing operation of the operation button 41 becomes easy, and the switching operation such as the air volume and the operation mode can be easily performed. Alternatively, each operation button 41 may have a pressing surface raised in a curved surface.

Each operation button 41 is arranged in a region (that is, an inclined surface 20b) between the front surface portion 11a of the main body portion 11 and the front surface portion 20a of the grip portion 20. As a result, the user can perform the pressing operation of the operation button 41 by using the same finger (for example, thumb) as the hand holding the grip portion 20.

Further, by arranging each operation button 41 on the inclined surface 20b, the pressing direction of each operation button 41 can be made different from the direction vector of the wind sending direction (that is, the Z direction).

This point will be described with reference to FIG. In FIG. 10, the direction of wind blowing from the outlets 12a and 12b is indicated by the broken line arrow A. Further, in FIG. 10, the pressing direction of the operation button 41 is indicated by the arrow B of the alternate long and short dash line. In the configuration according to the present embodiment, the wind blowing direction (arrow A) is the same as the axial direction (Z direction) of the main body 11.

As shown in FIG. 10, since the operation button 41 is arranged on the inclined surface 20b, the pressing direction of the operation button 41 is not the same as the axial direction (Z direction) of the main body portion 11, but the axis of the main body portion 11. It is inclined with respect to the direction (Z direction). For example, the angle θ in the pressing direction of the main body 11 with respect to the axial direction (Z direction) is preferably 15 degrees or more.

When the operation button 41 is operated while the hair dryer 10 is being operated (that is, while the wind is blowing out), the direction of the operator's line of sight is often substantially the same as the pressing direction of the operation button 41. Therefore, the operator sees the operation unit 40 from the grip portion 20 side of the hair dryer 10. At this time, as described above, the pressing direction of each operation button 41 is different from the direction vector of the wind sending direction (that is, the Z direction), so that when the operation button 41 is operated, it blows out to the operator's face. It is possible to avoid direct contact with the wind from the mouths 12a and 12b. That is, when the operation button 41 is operated, the operator can be less likely to be affected by the wind from the outlets 12a and 12b.

The power switch 42 is provided below each operation button 41. The power switch 42 is provided on the front surface portion 20a of the grip portion 20. By operating the power switch 42, the hair dryer 10 starts or stops operation. The power switch 42 is a slide type switch that slides in the vertical direction.

As shown in FIGS. 1 and 3, the power switch 42 has the highest height from the arrangement surface (front portion 20a and inclined surface 20b) as compared with the other operation buttons 41 included in the operation unit 40. It has become. That is, each operation button 41 is arranged substantially flush with the inclined surface 20b, whereas the power switch 42 is provided so as to project from the front portion 20a. Even if the power switch 42 is a sliding type as in the present embodiment, the power switch 42 is erroneously placed on the inclined surface 20b when the power switch 42 is operated because the power switch 42 projects to the front side (Z1 side). It is possible to reduce the possibility of pressing the operating button 41.

Further, although the power switch 42 slides in the vertical direction, the power may be turned on when the switch is slid upward, and the power may be turned off when the switch is slid downward. When the power switch 42 is slid from the OFF position (lower position) to the ON position (upper position) using the thumb, the thumb is located near each operation button 41. With such a configuration, when the operation button 41 is to be operated immediately after the power switch 42 is turned on, the flow line of the thumb can be shortened, which improves convenience.

The air volume display unit 43 is provided below the power switch 42. The air volume display unit 43 is provided on the front surface portion 20a of the grip portion 20. In the example shown in FIG. 9, the air volume display unit 43 is composed of three LED lamps arranged in the vertical direction (Y direction). This is a configuration in which the air volume of the hair dryer 10 can be adjusted in three stages.

Then, when the current air volume of the hair dryer 10 is the first air volume (large air volume), the top LED lamp lights up. After that, when the air volume of the hair dryer 10 is switched from the first air volume (large air volume) to the second air volume (during the air volume) by operating the operation button 41b, the top LED lamp is turned off. , The LED lamp in the center lights up.

Further, when the air volume of the hair dryer 10 is switched from the second air volume (medium air volume) to the third air volume (small air volume) by operating the operation button 41b, the central LED lamp is turned off. The bottom LED lamp lights up. Further, when the air volume of the hair dryer 10 is switched from the third air volume (small air volume) to the first air volume (large air volume) by operating the operation button 41b, the bottom LED lamp is turned off. , The top LED lamp lights up. In this way, the air volume is cyclically switched by the operation button 41b.

Further, the display of small to large air volume may be represented by the number of LED lamps lit. For example, when the air volume is small, one LED lamp is turned on. In addition, when the air volume is high, the two LED lamps are turned on. When the air volume is large, three LED lamps are turned on. With such a configuration, it becomes easier to visually understand the magnitude of the air volume.

The air volume of the hair dryer 10 may change even when the operation mode is switched by the operation button 41a. In such a case, the air volume display unit 43 lights an LED lamp indicating the air volume corresponding to the corresponding operation mode.

In the hair dryer 10 according to the present embodiment, the operation unit 40 is provided on the same side as the side on which the display unit 30 is arranged. As a result, the user can operate each operation button 41 while looking at the operation unit 40, and can also confirm the display content on the display unit 30 arranged on the same side.

(Summary of the first embodiment)
The hair dryer 10 according to the present embodiment includes a main body portion 11 and a grip portion 20. The main body portion 11 has a front portion 11a in which the wind outlets 12a and 12b are arranged. The grip portion 20 has a front portion 20a on the same side as the front portion 11a of the main body portion 11. An inclined surface 20b is provided between the front surface portion 11a of the main body portion 11 and the front surface portion 20a of the grip portion 20. At least a part of the operation unit 40 (for example, the operation button 41) is arranged on the inclined surface 20b.

Since each operation button 41 is arranged on the inclined surface 20b, the pressing direction of each operation button 41 can be made different from the direction vector of the wind sending direction (that is, the Z direction). As a result, it is possible to prevent the wind from the outlets 12a and 12b from directly hitting the operator's face when the operation button 41 is operated. Therefore, it is possible to improve the operability when the user performs the setting changing operation while the hair dryer 10 is being operated. It is preferable to apply the configuration according to the present embodiment to a hair dryer capable of blowing a higher speed wind (for example, a wind having a wind speed of 15 m / s or more).

Further, the hair dryer 10 according to the present embodiment is provided with a plurality of outlets 12a and 12b on the front side (Z1 side) of the main body 11. A blower portion 150, a blower path, and the like are provided inside the main body portion 11. The blowing path is divided into a plurality of blowing paths such as the first blowing path FA and the second blowing path FB at the outlet of the blowing section 150 (that is, the front end of the ventilation path F2). Of the plurality of ventilation paths, the first ventilation path FA is connected to the first outlet 12a. Further, the second ventilation path FB is connected to the second outlet 12b.

Since the air passages from the outlet of the air blower 150 to the air outlets 12a and 12b are divided, the front-rear direction of each air passage connected to each air outlet is suppressed while suppressing the increase in the size of the main body 11. The distance can be secured. As a result, it is possible to obtain a hair dryer 10 capable of blowing out a good wind from each outlet while suppressing an increase in the size of the product (particularly, the distance from the fan to the outlet).

<Second embodiment>
Subsequently, a second embodiment of the present invention will be described. In the first embodiment, a configuration in which a plurality of outlets are provided and the ventilation path is divided into a plurality of outlets corresponding to each outlet is described as an example. However, in the hair dryer according to one embodiment of the present invention, there may be only one outlet. Therefore, in the second embodiment, the hair dryer 210 having one outlet will be described as an example.

FIG. 11 shows the configuration of the front portion 11a of the hair dryer 210 according to the second embodiment. The hair dryer 210 according to the present embodiment has one outlet 212. The outlet 212 is formed in a substantially annular shape (a ring with a part missing) along the outer circumference of the front portion 11a. In other words, the outlet 212 has a shape in which the two outlets 12a and 12b according to the first embodiment are connected to one.

Further, although not shown, in the hair dryer 210 according to the present embodiment, the blowing path from the outlet of the blowing section 150 to the blowing port 212 is not divided and is composed of one blowing path. That is, the hair dryer 210 according to the present embodiment is not provided with the first air passage dividing portion 171 as described in the first embodiment. As in the first embodiment, the third ventilation path FC may be provided.

Further, as in the first embodiment, the hair dryer 210 has an inclined surface 20b between the front surface portion 11a of the main body portion 11 and the front surface portion 20a of the grip portion 20. At least a part of the operation unit 40 (for example, the operation button 41) is arranged on the inclined surface 20b.

For configurations other than the above, substantially the same configurations as in the first embodiment can be applied. Therefore, detailed description will be omitted.

<Third embodiment>
The hair dryer according to another aspect of the present invention may be configured not to be provided with an ion generator. That is, the hair dryer 10 according to the third embodiment of the present invention is not provided with the ion generator 180. Since the hair dryer 10 according to the embodiment does not have the ion generator 180, the operation mode does not include the hair care mode (ion blowing mode). Since the same configuration as that of the first embodiment can be applied to other configurations, detailed description thereof will be omitted.
