  Hereinafter, the present invention will be described through the embodiments of the invention, but the invention according to the claims is not limited to the following embodiments. Moreover, not all the configurations described in the embodiments are necessarily essential as means for solving the problems.

  FIG. 1 is an overall perspective view of a hair dryer 100 according to the present embodiment. The hair dryer 100 mainly includes a main unit 110 that generates hot air and cold air, and a grip unit 180 that the user grips. The hair dryer 100 generates heat and an air flow by the power supplied from the AC power source.

  In the main unit 110, a housing 116, which is a housing, surrounds the outer periphery to form a cylindrical shape, takes in outside air from an inlet 111, which is an opening at one end, and is adjusted from an outlet 112, which is an opening at the other end. Blow out an air stream. The air outlet 112 is divided into two, and is constituted by a first air outlet 113 for blowing out a relatively large amount of air flow, and a second air outlet 114 for discharging the air flow smaller than the first air outlet. . In the following description, the suction port 111 side is referred to as the upstream side, and the blowout port 112 side is referred to as the downstream side.

  The main unit 110 has an end connected to the grip unit 180. In the vicinity of the end, a toggle mode switch 115 is provided. The mode switch 115 functions as a switching unit that switches between a cosmetic mode in which the cosmetic component is released to the air flow blown out and a non-cosmetic mode in which the cosmetic component is not released. The user operates mode switch 115 to switch to a desired mode.

  The grip unit 180 is pivotally connected to the main body unit 110 at one end side, and the user holds the grip unit 180 upright with respect to the main body unit 110 at the time of use and folds parallel to the storage time. The grip unit 180 has an on / off switch 181 near the center of the grip portion. The user can slide the on / off switch 181 into any of three positions. Each position is a cold air position in which one is an off position, one cuts off the current supply to the heater to be described later and sends cold air, and one is a hot air position in which the heating wire is current supplied and warm air is sent.

  When the user operates the mode switch 115 to switch to the beauty mode, the air flow mixed with the beauty component is discharged from the second outlet 114. The cosmetic component is adsorbed and held by the cartridge 150 as a cosmetic component holding member. The cartridge 150 is exchangeably attached to the main body unit 110. That is, the cartridge 150 which has exhausted the cosmetic component is replaced with a new cartridge 150. Thereby, the hair dryer 100 can maintain radiation | emission of a cosmetics component continuously.

  FIG. 2 is a partially enlarged view showing how the main body unit 110 mounts the cartridge 150. As shown in FIG. An opening is provided in a part of the housing 116, and the opening is covered with the housing lid 117 in normal use. The housing lid 117 is pivoted on the housing 116 by a hinge provided at one end side, and the user lifts the other end side of the housing lid 117 to open the opening when the cartridge 150 is replaced. A mounting portion 118 is provided at the back of the opening, and the user can mount the cartridge 150 on the mounting portion 118. By mounting the cartridge 150 and closing the containing lid 117, the user can operate the beauty mode of the hair dryer 100. The mode switch 115 may be provided with a lock mechanism so that the mode switch 115 can not be switched to the cosmetic mode when the cartridge 150 is not attached.

  FIG. 3 is a view schematically showing a central cross section of the housing 116 cut in a cross section parallel to the xz plane shown in the coordinate system of FIG. The figure shows only the main components. Specifically, the heater 121, the motor 122, the fan 123, the atomizing device 130, and the cartridge 150 mounted on the mounting unit 118, which are disposed in the housing 116, are shown.

  The fan 123 is rotated by the motor 122, takes in the outside air from the inlet 111, and generates an air flow toward the outlet 112. The motor 122 is, for example, a direct current motor, and functions as a blower together with the fan 123. The heater 121 generates heat by being energized, and heats the air flow generated by the fan 123 to convert it into warm air. The heater 121 is, for example, a heating wire, and is fixed so as to be positioned in the hollow portion of the housing 116 by being wound around an insulating plate or the like.

  The inner space of the housing 116 is divided into two by the inner wall 119 so that the outside air taken in from the suction port 111 is branched downstream on the downstream side of the fan 123. That is, the air flow generated by the fan 123 is divided by the inner wall 119 into an air flow B 0 directed to the first outlet 113 and an air flow B 1 directed to the second outlet 114. The heater 121 is disposed in the flow path of the air flow B0 so as to warm the air flow B0. Therefore, when the user sets the on / off switch 181 to the warm air position, the energized heater 121 mainly heats the air flow B0.

  The atomization device 130 is disposed in the flow path of the air flow B1. The atomization device 130 is a dew condensation water atomization device that condenses water contained in the ambient air, mists (atomizes) the condensed water, and applies the mist to the air flow B1. The specific configuration will be described later.

  The cartridge 150 is mounted to a mounting portion 118 provided downstream of the atomizing device 130. When the mist charged to negative ions passes through the inside of the cartridge 150, the cosmetic component adsorbed and held by the cartridge 150 is eluted into the mist, and the air flow B1 discharged from the second outlet 114 appropriately adjusts the cosmetic component. Reach the user's hair in the included state.

  As shown in the figure, the inner wall 119 intervenes between the atomizing device 130 and the heater 121 and is isolated from each other, so the heat generated by the heater 121 does not easily reach the dew condensation part of the atomizing device 130 . Therefore, the dew condensation part can condense more moisture. Further, the inner wall 119 may be formed of a highly heat insulating material so as to further block the heat of the heater 121. Alternatively, a heat insulating sheet that blocks heat transfer may be attached to the surface of the inner wall 119.

  FIG. 4 is a view schematically showing the atomizing device 130, and is an enlarged view of the atomizing device 130 shown in FIG. The atomization device 130 mainly includes a Peltier element 131, a cooling plate 132, a heat radiation fin 133, a discharge electrode 134, a piezo element 135, and a heat insulating material 136.

  A conductive cooling plate 132 is bonded to the heat absorption surface side of the Peltier device 131, and the cooling plate 132 is cooled by the Peltier device 131. Even if the cooling plate 132 is not directly bonded to the cooling surface of the Peltier device 131, it may be thermally connected, for example, by interposing a good thermal conductor.

  The cooling plate 132 is a thin plate of a good thermal conductor, and for example, a stainless steel plate is used. The cooling plate 132 has a contact portion 132a that faces and contacts the cooling surface of the Peltier element 131, and a vibrating portion 132b that extends from the contact portion 132a in the upstream direction (x-axis minus direction). The heat insulating material 136 is fixed so as to cover the surface of the contact portion 132 a of the cooling plate 132 opposite to the surface in contact with the cooling surface of the piezoelectric element 135. For example, a urethane sheet is used as the heat insulating material 136. Therefore, most of the contact portion 132a does not contact the air flow B1 directly, so that little condensed water is generated on this surface.

  The surface of the vibrating portion 132b of the cooling plate 132 in contact with the air flow B1 cools the air flow B1 to condense the moisture contained therein. That is, the vibrating portion 132 b of the cooling plate 132 functions as a dew condensation portion in cooperation with the Peltier element 131. Note that the dew condensation portion condenses the moisture contained in the air flow B1 when the fan 123 is rotating, but it condenses the moisture from the surrounding air even in the case of non-flow where the fan 123 is not rotating. You can also

  A piezo element 135 is attached to the tip of the vibrating portion 132b. The piezo element 135 is connected to a piezo circuit to be described later, and expands and contracts by applying a pulse voltage to cause the vibrating portion 132 b to generate vibration. The vibration generated by the piezoelectric element 135 scatters condensed water as the mist WD. That is, the atomizing device 130 functions as a device that cools the moisture in the air to generate mist (atomized droplets), and in the present embodiment, droplets having a diameter of ten to several hundreds of nanometers. Generate In the figure, the mist WD is drawn large.

  As means for generating the mist WD, only the piezo element 135 may be used, but in the present embodiment, the mist WD can be generated also by the discharge electrode 134. The discharge electrode 134 is connected to an electrode circuit to be described later, and is disposed apart from the vibrating portion 132 b of the cooling plate 132 by a predetermined amount so that a discharge is generated with the cooling plate 132 as a ground electrode. When a high voltage negative pulse is applied to the discharge electrode 134, a discharge occurs between the tip of the discharge electrode 134 and the cooling plate 132, and the dew condensation water condensed on the condensation surface of the cooling plate 132 causes Rayleigh splitting. It disperses as mist charged to negative ions. That is, the atomization device 130 applies the mist (electrostatically atomized droplets) charged to negative ions to the air flow B1.

  Thus, the hair dryer 100 can also supply negative ions to the hair and scalp by providing the discharge electrode 134 as well. Negative ions can further tighten the hair cuticle and maintain higher moisture retention. In addition, if the vibrating portion 132b is vibrated by the piezo element 135 and a discharge is generated by the discharge electrode 134, it is possible to simultaneously generate mist having different diameters. If mists of different diameters can be simultaneously generated, in the case where the cartridge 150 adsorbs and holds a plurality of cosmetic components, mists of convenient diameters can be supplied to each.

  Further, if an ion mode switch is provided so that on / off of negative ion emission can be selected, mist may be generated by the piezo element 135 when the ion mode switch is off, and may be generated by the discharge electrode 134 when it is on. . That is, the atomization device 130 vibrates the piezo element 135 without generating discharge at the discharge electrode 134 and scatters mist, and generates discharge at the discharge electrode 134 without vibrating the piezo element 135. You may comprise so that the mode which scatters can be selected.

  The atomizing device 130 may also be able to select a mode in which the piezoelectric element 135 is vibrated and a discharge is generated at the discharge electrode 134 to scatter the mist. By using such a mode, a large amount of mist can be generated in a short time. In this case, the mist can be generated more efficiently by controlling the vibration of the piezo element 135 and the timing of the discharge of the discharge electrode 134. Specifically, for example, if the discharge is generated at the timing when the discharge position of the vibrating portion 132b inclines due to the vibration of the piezoelectric element 135, the mist WD can be scattered in the air flow B1 direction.

  On the heat generating surface side of the Peltier element 131, a radiation fin 133 for heat radiation is attached. The heat released from the heat radiation fins 133 rides on a part of the air flow B1 and is discharged to the outside from the second air outlet 114. In the atomizing device 130, the dew condensation part may not be disposed directly in the flow path of the air flow B1. If the dew condensation water condensed on the dew condensation surface becomes mist, if the mist is attracted to the air flow B1, it may be disposed at a location not directly exposed to the air flow B1.

  FIG. 5 is an overall perspective view of the cartridge 150. As described above, the cartridge 150 is a cosmetic component holding member that adsorbs and holds cosmetic components. The cosmetic components adsorbed and held are released to the air flow B1 using the mist generated by the atomization device 130 as a medium. As the cosmetic ingredients, for example, those having moisturizing properties include proteins, mucopolysaccharides, collagen, elastin, keratin, vitamins and the like. In addition, as a cosmetic component, although it can select arbitrarily and use except the above-mentioned, from a viewpoint of improving the moisture retention etc. in hair etc. and recovering the pain of a cuticle etc., it is collagen as a cosmetic component. Is preferred.

  In addition, metal fine particles can also be adopted as a cosmetic component, for example, according to an embodiment such as supporting on collagen. Gold, silver, copper, platinum, zinc and titanium can be mentioned as candidates as metals that can be cosmetic components. Such metal fine particles can be attached to the hair to produce an antibacterial action or an antioxidant action. In particular, fine particles of platinum are known to have extremely high antioxidative action, and may be employed as a cosmetic component.

  The cartridge 150 is configured of a main body portion 151 and a plurality of through holes 152 provided in the main body portion 151. The main body portion 151 is preferably made of a porous material, and is, for example, a ceramic sintered body. Since the void of the porous material can be used as a space for adsorbing and holding the cosmetic component, the main body 151 can hold a large amount of cosmetic component as compared with the case where it is not a porous material.

  The plurality of through holes 152 are provided along the air flow B1 when the cartridge 150 is mounted to the mounting portion 118. In other words, the mounting portion 118 is defined in a storage shape such that the cartridge 150 is mounted in the direction in which the through hole 152 follows the air flow B1. Therefore, at least a part of the air flow B1 passes through the inside of the through hole 152.

  When the air flow B1 containing the mist generated by the atomization device 130 passes through the through hole 152, the cosmetic component penetrates so that the mist contacts the inner surface of the through hole 152 and dissolves the cosmetic component. It is adsorbed on the inner surface of the hole with a certain thickness. When the cosmetic component adsorbed and held on the inner surface of the through hole 152 is consumed by the use of the hair dryer 100 and the cosmetic component exuding from the void of the porous material is also consumed, the cartridge 150 comes to be replaced.

  FIG. 6 is a system configuration diagram of the hair dryer 100. The entire electric system is controlled by the control unit 190 which is, for example, a microprocessor. The switch state of the on / off switch 181 and the switch state of the mode switch 115 are electrically detected and transmitted to the control unit 190. The control unit 190 controls each circuit in accordance with the switch state. The control targets are mainly a heater circuit 191, a motor circuit 192, a Peltier circuit 193, an electrode circuit 194 and a piezo circuit 195.

  The heater circuit 191 is a circuit which energizes the heater 121 to maintain a constant heat generation state. The controller 190 controls the heater circuit 191 to function when the on / off switch 181 is at the warm air position. The motor circuit 192 is a circuit that energizes the motor 122 to rotate the fan 123 at a constant rotational speed. The controller 190 controls the motor circuit 192 to function when the on / off switch 181 is in the cold air position or the warm air position.

  The Peltier circuit 193 is a circuit that drives the Peltier element 131 to move heat from the heat absorption surface to the heat generation surface. The control unit 190 controls the Peltier circuit 193 to function when the dew condensation unit generates condensation water. The electrode circuit 194 is a circuit that applies a high voltage negative pulse to the discharge electrode 134 to periodically generate a discharge between the discharge electrode 134 and the cooling plate 132. The control unit 190 controls the electrode circuit 194 to function in the case of generating negative ions and scattering condensed water. The piezo circuit 195 is a circuit that vibrates the piezo element 135 by applying a periodic pulse voltage. The control unit 190 performs control so that the piezo circuit 195 functions when scattering condensed water.

  Next, another embodiment of the atomizing apparatus will be described. FIG. 7 is a view schematically showing an atomizing device 230 of another embodiment. Fig.7 (a) is principal part sectional drawing which observed the atomization apparatus 230 from the 2nd blower outlet 113 side, FIG.7 (b) observed the atomization apparatus 230 from the side similarly to FIG. It is principal part sectional drawing. The same elements as in the atomizing device 130 are given the same reference numerals, and the description thereof is omitted.

  Similar to the cooling plate 132 of the atomizing device 130, the cooling plate 232 of the atomizing device 230 is a thin plate of a good thermal conductor. Further, like the cooling plate 132, the cooling plate 232 has a contact portion 232a and a vibrating portion 232b, and the contact portion 232a faces and contacts the cooling surface of the Peltier element 131 similarly to the contact portion 132a. However, the configuration of the vibrating portion 232b is different from that of the vibrating portion 132b.

  The vibrating portion 232 b is disposed at an end portion of the cooling surface of the Peltier element 131 so as to be bent along a bending line parallel to the x axis which is a boundary with the contact portion 232 a and to hang downward. Here, the lower side is the z-axis negative direction which is the gravity direction in the normal use state of the hair dryer 100. The vibrating portion 232b is shaped so as to narrow at the lower side, and the generated dew condensation water is gathered by gravity and concentrated at one place at the lower end. In addition, a guide groove 232c is provided on the surface so that condensation water can be collected smoothly. The guide grooves 232c are, for example, a plurality of grooves inclined from the outside toward the center as shown in FIG. 7 (b).

  The vibrating portion 232 b arranged in this manner can also cool the air flow B 1 to generate condensation water. Then, when the piezo element 135 disposed in the vicinity of the bending line in the vibrating portion 232b is vibrated, the tip portion vibrates largely, and the collected condensed water can be efficiently scattered into the air flow B1. In addition, even if discharge is generated by the discharge electrode 134 disposed to face the front end, the collected condensed water can be scattered into the air flow B1.

  FIG. 8 is a view schematically showing an atomizing apparatus 330 according to still another embodiment. FIG. 8 is a cross-sectional view of the main part of the atomizing device 330 observed from the second outlet 113 side as in FIG. 7A. The same elements as in the atomizing device 130 are given the same reference numerals, and the description thereof is omitted.

  The atomization device 330 includes two Peltier elements 131. In the radiation fin 333 of the atomization device 330, the contact surface 333a in contact with the heat generating surface of each Peltier element 131 is an inclined surface which is inclined toward the flow path center vicinity of the air flow B1. Each Peltier element 131 is fixed to the contact surface 333a.

  Similar to the cooling plate 132 of the atomizing device 130, the cooling plate 332 of the atomizing device 330 is a thin plate of a good thermal conductor. In the cooling plate 332, the side portions are contact portions 332a in contact with the cooling surfaces of the respective Peltier elements 131, and the central portion connecting both side portions is bent with the vicinity of the flow path center of the air flow B1 as an apex The vibrating portion 332 b forms That is, the cooling plate 232 is disposed in a substantially V shape in the cross section shown in FIG.

  The apex of the cooling plate 232 is located in the z-axis minus direction, which is the direction of gravity in the normal use state of the hair dryer 100, so the condensed water generated on the surfaces of the contact portion 332a and the vibrating portion 332b is attracted by gravity. Collect and concentrate on the top. In addition, guide grooves may be provided on the surfaces of the contact portion 332 a and the vibrating portion 332 b so that the condensed water can be gathered up smoothly.

  The piezoelectric element 135 is attached to the inside (the radiation fin 333 side) of the top of the cooling plate 332. By vibrating the piezoelectric element 135 disposed at the top, which is the lower end in the direction of gravity, as described above, the top vibrates more, and the condensed water collected can be efficiently scattered into the air flow B1. . In addition, even if discharge is generated by the discharge electrode 134 disposed to face the outside of the apex, the condensed water collected can be scattered into the air flow B1. Unlike the atomizing devices 130 and 230, the atomizing device 330 may not cover the surface of the contact portion 332a with the heat insulating material 136. Condensed water that condenses on the surface of the contact portion 232a also moves to the lower end along the slope, so a large amount of condensed water can be collected.

  FIG. 9 is a view schematically showing an atomizing device 430 according to still another embodiment. FIG. 9 is a cross-sectional view of an essential part of the atomizing device 430 observed from the second outlet 113 side as in FIG. 7A. The same elements as in the atomizing device 130 are given the same reference numerals, and the description thereof is omitted.

  The atomization device 430 includes two Peltier elements 131. In the radiation fin 433 of the atomizing device 430, the contact surface in contact with the heat generating surface of each Peltier element 131 is directed in the z-axis positive direction, and the fin for radiating heat is disposed in the z-axis negative direction. . Each Peltier element 131 is fixed on the heat dissipating fin 433 such that the heat generating surface is in contact with the contact surface of the heat dissipating fin 433.

  Similar to the cooling plate 132 of the atomizing device 130, the cooling plate 432 of the atomizing device 430 is a thin plate of a good thermal conductor. The cooling plate 432 has a contact portion 432a whose side is in contact with the cooling surface of each Peltier element 131, and a vibrating portion 432b whose central portion connecting both sides is located in the vicinity of the flow path center of the air flow B1. It has become. The cooling surface of the Peltier element 131 and the contact portion 432 a are adhered to each other via an elastic adhesive layer 439. The elastic adhesive layer 439 is a layer formed of an elastic adhesive, and has a property of absorbing the vibration generated at the contact portion 232a. As the elastic adhesive, one having good thermal conductivity is used. For example, what the metal paste was kneaded is used.

  The piezoelectric element 135 is attached to the inner side (the heat dissipating fin 433 side) of the central portion of the cooling plate 432. By vibrating the piezoelectric element disposed in the center in this manner, the piezoelectric element can be largely vibrated about the vibrating portion 432b and can be vibrated to the contact portions 432a on both sides. It can be scattered into B1. In addition, even if a discharge is generated by the discharge electrode 134 disposed opposite to the outside of the central portion, the generated condensed water can be scattered into the air flow B1. According to the atomization device 430, the dew condensation water is generated on the upper surface of the cooling plate 132, so it is possible to suppress the generation of water droplets dripping from the atomization device.

  As mentioned above, according to the hair dryer 100 in this embodiment described including other examples, it is possible to generate uncharged mist without using a water supply means such as a water storage tank. In addition, in this embodiment, although the case where each atomization apparatus was equipped with a discharge electrode was demonstrated, you may be the structure which does not have a discharge electrode. When generating negative ions, an ion generation unit independent of the atomization device may be provided.

  In the present embodiment, a negative pulse is applied to the discharge electrode 134 to generate negative ions, but a positive pulse may be applied to generate positive ions. When a positive pulse is applied to generate discharge, mist charged to positive ions is generated. In this case, positive ions reach the user's hair, and the antibacterial effect of the positive ions can be expected. Also, by changing the polarity of the pulse applied to the discharge electrode 134, negative ions and positive ions may be sequentially generated. Further, a plurality of discharge electrodes 134 may be provided to simultaneously generate positive ions and negative ions.

  Moreover, although the hair dryer 100 according to the present embodiment described above adopts the replaceable cartridge 150 as the cosmetic component holding member, it is not a cartridge type, for example, a cosmetic component holding member capable of externally injecting a cosmetic component. It may be adopted. The cosmetic component holding member in this case may be fixed to the main unit 110.

  As described above, the cosmetic components adsorbed and held by the cartridge 150 are optional. For example, separate cosmetic components can be adsorbed and held by the cartridge A and the cartridge B which can be mounted. The user selects the cartridge in accordance with the desired effect. In such a case, the control unit 190 may switch whether to generate the mist by vibrating the piezo element 135 or to generate the mist by the discharge of the discharge electrode 134 according to the property of the mounted cartridge. .

  With the configuration as described above, the hair dryer 100 according to the present embodiment can supply a cosmetic component to the hair and scalp of the user who uses it. Therefore, hair damage such as exfoliation of the cuticle on the surface of the hair can be more effectively repaired, and furthermore, moisturizing of the hair can be performed more effectively. In particular, since the hair dryer 100 can supply mist and a cosmetic component to the hair each time the user uses it, the cuticle can be tightened more by continuing to use it, and damage due to heating due to brushing or warm air etc. It is possible to keep the hair in a more moisturizing state. In addition, generation of sebum in the scalp can be suppressed to keep the pores clean. Furthermore, it is possible to suppress fading when hair coloring is performed, and it is also expected to maintain the dyed hair color for a long time. In addition, since the above-described hair dryer 100 can also supply negative ions to the hair and scalp, it can further tighten the hair cuticle and maintain higher moisture retention.

  Moreover, in the present embodiment, although the embodiment in which the atomizing device is mounted on the hair dryer 100 has been described, it is also possible to incorporate the atomizing device into another device and use it. For example, it can be incorporated into an apparatus for moisturizing dry skin.
