Description

The present invention relates to a hair dryer.

There are known dryers that irradiate hair with negative ions to eliminate charged positive charges, or irradiate hair with positive ions to obtain a sterilizing effect. The user selects the polarity of the ion to be irradiated according to the condition of the hair and the desired effect (see, for example, Patent Document 1).

Japanese Unexamined Patent Publication No. 2008-49101

Since the ions irradiated from the hair dryer cannot be visually recognized, excessive ion irradiation may be performed, which may adversely affect the effect. In essence, the polarity and amount of ions to be irradiated should be determined according to the condition of the hair, but it is difficult to determine these while detecting the condition of the hair in real time. It is also not desirable for the hair dryer to ignore the user's will and make these decisions.

The present invention has been made to solve such a problem, and an object of the present invention is to provide a hair dryer that generates a preferable amount of ions for hair while respecting the will of the user.

The hair dryer according to the specific embodiment of the present invention includes an ion generating unit, a time measuring unit that measures the usage time, and an adjusting unit that adjusts the amount of ions generated by the ion generating unit based on the usage time measured by the timing unit. To prepare for. With such a hair dryer, even when ions are generated according to the user's settings, the amount of ions generated is controlled according to the usage time, so that the amount of ions generated is not significantly deviated from the amount of ions desirable for hair. can do. For example, it is possible to control the amount of ions by generating a large amount of ions for a while after starting the use, and then suppressing the amount of ions to the extent of neutralizing the static electricity continuously generated by combing. Moreover, since it is adjusted based on the usage time, complicated sensors are not required.

In the above-mentioned hair dryer, the ion generating section has a positive ion generating section for generating positive ions and a negative ion generating section for generating negative ions, and the adjusting section has a usage time measured by the metering section. The amount of positive ions generated by the positive ion generating portion and the amount of negative ions generated by the negative ion generating portion may be adjusted independently. As described above, since negative ions and positive ions have different effects on hair, it is preferable to independently adjust the amount of each ion generated with respect to the usage time.

Further, the above-mentioned hair dryer is provided with a selection member capable of selecting a negative ion generation mode in which negative ions are generated independently, and the adjusting unit is predetermined by a timing unit when the negative ion generation mode is selected by the selection member. When the time taken is timed, the ratio of the amount of positive ions to the amount of negative ions may be configured to be larger than the previous ratio. Further, a selection member capable of selecting a positive ion generation mode in which positive ions are generated independently is provided, and the adjusting unit measures a predetermined time when the positive ion generation mode is selected by the selection member. Then, the ratio of the amount of negative ions to the amount of positive ions may be configured to be higher than the previous ratio. With these configurations, one ion can be neutralized with the other ion so that the other ion does not continue to be irradiated and the adverse effect does not occur. It is also possible to neutralize the electric charge accumulated in the outlet of the hair dryer.

Further, in the above hair dryer, the adjusting unit may have different amounts of ions generated by the ion generating unit depending on whether hot air is blown or cold air is blown. By adjusting in this way, it is possible to deal with the problem that the amount of ions reaching the hair when warm air is blown is reduced.

Further, in the above hair dryer, the ion generating unit has a plurality of electrodes that generate ions of the same electrode, and the adjusting unit is an electrode that generates ions from a plurality of electrodes based on the usage time measured by the timing unit. May be configured to select at least one. With this configuration, it is possible to adjust how the ions generated for the blown air flow are distributed to some extent, so that the effects of the ions on the hair can be made different with the passage of time.

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

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

The main body unit 110 has a cylindrical shape as a whole, takes in outside air from the suction port 111 which is an opening on one end side, and blows out an adjusted air flow from an air outlet 112 which is an opening on the other end side. Further, the main body unit 110 has an end portion connected to the grip unit 180. A hot / cold switch 171 is provided in the vicinity of the end portion to switch between a hot air mode in which the heating wire to be described later is energized to send out hot air and a cold air mode in which the energization to the heating wire is cut off to send out cold air. There is.

One end of the grip unit 180 is rotatably connected to the main body unit 110, and the user makes the grip unit 180 stand upright with respect to the main body unit 110 during use and folds the grip unit 180 in parallel during accommodation. The grip unit 180 has a mode selection switch 181 near the center of the grip portion. The mode selection switch 181 has a "positive ion mode" position for generating positive ions, a "negative ion mode" position for generating negative ions, and both positive and negative ions, in addition to the "off" position for disabling the use. It has 4 positions of "both ion mode" positions to generate. When the user slides from the "off" position to any mode position, the fan described below begins to rotate and the airflow adjusted according to the setting of the hot / cold switch 171 and the selected mode position is blown out from the outlet.

FIG. 2 is an exploded perspective view of the main parts of the main body unit 110. The main body unit 110 includes an insulating member 120, a fan 130, a motor 132, a heating wire 134, an ion electrode 150, and a blowout grill 160 as main components. The left and right housings 141 and 142, the through cylinder 143 and the tip ring 144 surround these elements as a housing.

The fan 130 is rotated by a motor 132 to take in outside air from the suction port 111 and generate an air flow toward the air outlet 112. The motor 132 is, for example, a DC motor and functions as a blower together with the fan 130. The heating wire 134 generates heat when it is energized, and heats the air flow generated by the fan 130 to convert it into warm air.

The insulating member 120 is a structure in which a vertical insulating plate 121 and a horizontal insulating plate 122, which are insulating plates formed of, for example, a mica plate, are crossed and assembled in a cross shape. A plurality of locking grooves 120a are provided on the peripheral edge of the insulating member 120, and the heating wire 134 is wound around the locking grooves 120a and fixed with the insulating member 120 as a substrate. Further, the suction port 111 side is cut out to form an accommodation space 120b for accommodating the fan 130 and the motor 132. In the present embodiment, the insulating member 120 is formed by combining two insulating plates, but the number of the insulating plates to be combined may be three or more. Further, for example, it may be a molded block-shaped structure.

The ion electrode 150 includes a negative ion electrode 151 and a positive ion electrode 152, and each is connected to an ion generation circuit described later. The negative ion electrode 151 is fixed to the horizontal insulating plate 122, and the positive ion electrode 152 is fixed to the vertical insulating plate 121. The specific arrangement relationship will be described later.

The outlet grill 160 is a circular member having a mesh surface made of a conductive material, and plays a role of preventing foreign matter from entering the inside from the outlet 112. At the same time, when the ion electrode 150 generates ions, it functions as a counter electrode. The outlet grill 160 is fixed in the vicinity of the outlet 112 via the tip ring 144. The blowout grill 160 is made of a conductive material, and a metal material such as iron is preferably used.

The through-cylinder 143 accommodates each element constituting the main body unit 110 and has a function of rectifying the internal air flow. The housings 141 and 142 are fixed to a part of the side surface of the through cylinder 143 and function as a connection portion with the grip unit 180.

FIG. 3 is an enlarged view of the vicinity of the blowout grill 160. However, the figure shows the blowout grill 160 slightly separated from the insulating member 120 with respect to the actual assembled state.

The central portion of the end face of the vertical insulating plate 121 facing the blowout grill 160 is cut out in a U shape. The horizontal insulating plate 122 also has a U-shaped notch at the center of the end faces facing the blowout grill 160. These notches form a notch space 120c between the outlet grill 160 and the insulating member 120. The positive ion electrode 152 is fixed in the vicinity of the notch portion of the vertical insulating plate 121, and the tip portion thereof protrudes toward the notch space 120c. Further, the negative ion electrode 151 is fixed in the vicinity of the notch portion of the horizontal insulating plate 122, and the tip portions of the first electrode 151a, the second electrode 151b, and the third electrode 151c branched into three are each in the notch space 120c. It protrudes toward you.

Both side portions of the notched portion of the vertical insulating plate 121 are contact ends 121a that abut on the mesh 160a of the blowout grill 160, and support the mesh 160a surface to resist external pressing force. Further, both side portions of the notched portion of the horizontal insulating plate 122 are contact ends 122a that abut with the mesh 160a of the blowout grill 160, and like the contact end 121a, support the mesh 160a surface and pressurize from the outside. Against.

The mesh 160a of the outlet grill 160 includes four first targets 160b to fourth targets 10e formed in a partially annular shape rather than in a grid pattern. The first target 160b is provided at a position where the center of the annulus faces the tip of the positive ion electrode 152. Similarly, the center of the annulus of the second target 160c is at the tip of the first electrode 151a of the negative ion electrode 151, and the center of the annulus of the third target 160d is at the tip of the second electrode 151b. The target 160e is provided at a position where the center of the ring is opposed to the tip of the third electrode 151d.

When a high-voltage positive pulse voltage is applied to the positive ion electrode 152, a discharge occurs between the tip thereof and the first target 160b, and plasma is generated. At this time, water molecules in the air are ionized to generate hydrogen ions (H ⁺ ). These hydrogen ions cluster with water molecules in the air to generate positive ions consisting of H ⁺ (H ₂ O) _m (m is an arbitrary natural number). Since the first target 160b has an annular shape that is equidistant from the tip of the positive ion electrode 152, the discharge positions are not concentrated in one place but are dispersed on the annulus, and damage to the mesh 160a can be reduced. can.

When a high-voltage negative pulse voltage is applied to the negative ion electrode 151, the third electrode 151c is between the tip of the first electrode 151a and the second target 160c, between the tip of the second electrode 151b and the third target 160d. A discharge occurs between the tip of the device and the fourth target 160d, and plasma is generated. At this time, oxygen molecules or water molecules in the air are ionized ^to generate oxygen ions O _2- . These oxygen ions cluster with water molecules in the air to generate negative ions consisting of O _2- ⁽ H ₂ O) _n (n is an arbitrary natural number). Since the second target 160c to the fourth target 160e also have an annular shape equidistant from the tips of the first electrode 151a to the third electrode 151c, the discharge positions are not concentrated in one place but dispersed on the annular shape. Therefore, damage to the mesh 160a can be reduced.

FIG. 4 is a diagram showing an outline of the ion generation circuit 190. In the ion generation circuit 190 according to the present embodiment, a positive ion generation circuit 191 that generates positive ions and a negative ion generation circuit 192 that generates negative ions are provided in parallel. Each circuit configuration mainly has a difference in whether the terminal of the diode D4 connected to one terminal of the secondary coil of the transformer TR ₁ is an anode or a cathode, and the other configurations are different. Is common. Therefore, unless otherwise specified in the following description, the configuration is common to both circuits.

The anode of the diode D1 is connected to _one end of the AC power supply, and _one terminal of the capacitor C1 and the cathode of the diode _{D3 are} mainly connected to the cathode of the diode D1 via the resistor _R1 . Has been done. The cathode of the diode D ₂ is mainly connected to the other end of the AC power supply via the resistor R ₂ , and the anode of the diode D ₃ is connected to the anode of the diode D ₂ . Then, the primary coil of the transformer TR ₁ is connected between the other terminal of the capacitor C ₁ and the anode of the diode D ₃ .

In the case of the positive ion generation circuit 191, the anode of the diode D ₄ is connected to one terminal of the secondary coil of the transformer TR ₁ , and the cathode of the diode D ₄ and the other terminal of the secondary coil are connected to each other. A capacitor C ₂ is connected between them. Further, a positive ion electrode 152 is connected to the cathode of the diode D ₄ via a resistor R ₆ . The positive ion electrode 152 generates positive ions by using the first target 160b of the blowout grill 160 as a counter electrode.

In the case of the negative ion generation circuit 192, the cathode of the diode D ₄ is connected to one terminal of the secondary coil of the transformer TR ₁ , and the anode of the diode D ₄ and the other terminal of the secondary coil are connected to each other. A capacitor C ₂ is connected between them. Further, the first electrode 151a, the second electrode 151b, and the third electrode 151c of the negative ion electrode 151 are connected to the anode of the diode D ₄ via the resistor _R6 . The first electrode 151a, the second electrode 151b, and the third electrode 151c generate negative ions by using the second target 160c, the third target 160d, and the fourth target 160e of the blowout grill 160 as counter electrodes, respectively. The outlet grill 160, which functions as a counter electrode both as a positive ion generating unit and as a negative ion generating unit, is connected to a ground wire.

Further, the triac TC ₁ is connected between both ends of the AC power supply. The gate of the TRIAC TC ₁ is connected to, for example, a control unit 200 configured by a microcomputer, and the duty ratio of power supply can be changed by phase control by the control unit 200. Since the amount of ions generated at the electrodes is approximately proportional to the duty ratio of the power supply, the control unit 200 can control the amounts of positive and negative ions generated by performing phase control.

The control unit 200 is connected to the timekeeping unit 201 and the setting unit 202. The timekeeping unit 201 is a timer that measures the usage time of the hair dryer 100, and returns the measured usage time according to the request of the control unit 200. The setting unit 202 is a state holding circuit that holds the setting state of the hot / cold switch 171 and the setting state of the mode selection switch 181. The control unit 200 confirms each setting state by accessing the setting unit 202. be able to. In particular, the control unit 200 controls the amount of ions to be generated according to the lapse of the usage time in which the user uses the hair dryer 100, based on the setting state of the heating / cooling switch 171 and the mode selection switch 181. That is, the control unit 200 functions as an adjustment unit for adjusting the amount of ions generated by the ion generation circuit 190. Details will be described later.

Although not shown in FIGS. 1 and 2, the ion generation circuit 190 is provided in the vicinity of the connection portion of the main body unit 110 with the grip unit 180. The location where the ion generation circuit 190 is installed may be another location. Further, the parameter values in the respective elements of the positive ion generation circuit 191 and the negative ion generation circuit 192 do not have to be the same. Further, not only the parameter values but also the circuit configurations may be different from each other.

Next, how to adjust the amount of ions to be generated with respect to the passage of time for the user to use the hair dryer 100 will be described. Conventional hair dryers equipped with an ion irradiation function continue to irradiate a constant amount of ions during use when the user selects the ion irradiation mode. Some hair dryers are equipped with an adjustment dial or the like so that the user can adjust the amount of ions, but the user often wonders how much ion amount should be adjusted because the irradiated ions cannot be visually recognized.

For example, it is known that when negative ions are irradiated to hair, it electrically neutralizes hair that is often positively charged, and further permeates water deep inside the hair to moisturize it. However, if the amount of negative ions is too large, the hair will be negatively charged this time, and the hair may swell as a whole. That is, excessive ion irradiation may lead to adverse effects or unfavorable secondary effects. It is possible to stop irradiation after a certain period of time, but it should be considered that the user has a desire to continue irradiating negative ions while the user selects and uses the negative ion mode. It is not preferable because it exists. In addition, the user often continues brushing while the hair dryer is being used, and there is also a request to remove the positive charge generated by brushing. Therefore, the hair dryer 100 in the present embodiment adjusts the amount of ions to be generated with respect to the passage of use time.

FIG. 5 is a diagram showing a first example of adjusting the amount of ions generated with respect to the usage time. In the figure, the vertical axis represents the target amount of ions to be generated, and the horizontal axis represents the elapsed time from the start of use. The same applies to the vertical and horizontal axes of the figures used in the following description. In FIG. 5, the solid line indicates a predetermined target generation amount of negative ions, and the dotted line indicates a predetermined target generation amount of positive ions.

When the control unit 200 confirms that the negative ion mode is selected with reference to the setting unit 202, the control unit 200 may reach the target amount of negative ions generated by the solid line according to the elapsed time measured by the time measuring unit 201. In addition, the on-duty ratio of the negative ion generation circuit 192 is adjusted. Specifically, _Is- , which is a relatively large amount from the start of use to time t ₁ , is adjusted as the target amount, the target amount is gradually reduced from time t ₁ to t ₂ , and relatively after time t ₂ . Adjust a small amount of _Ir- as the target amount. In the negative ion mode, the target amount of positive ions generated is set to 0.

When the control unit 200 confirms that the positive ion mode is selected with reference to the setting unit 202, the control unit 200 may reach the target amount of positive ions generated by the dotted line according to the elapsed time measured by the time measuring unit 201. In addition, the on-duty ratio of the positive ion generation circuit 191 is adjusted. Specifically, Is ₊ , which is a relatively large amount from the start of use to time t3 _, is adjusted as the target amount, the target amount is gradually reduced from time _t3 to _{t4 ,} and a relatively small amount after time t4. Ir ₊ is adjusted as the target amount. In the positive ion mode, the target amount of negative ions generated is set to 0.

When the control unit 200 confirms that both ion modes are selected with reference to the setting unit 202, the control unit 200 may reach the target amount of negative ions generated by the solid line according to the elapsed time measured by the time measuring unit 201. In addition, the on-duty ratio of the negative ion generation circuit 192 is adjusted, and the on-duty ratio of the positive ion generation circuit 191 is adjusted so as to reach the target generation amount of positive ions shown by the dotted line. The amount of ions _Is- , Is ₊ , _Ir- , Ir ₊ , and the elapsed times t ₁ , t ₂ , t ₃ , and t ₄ from the start of use are generated by the capacity of the ion generation circuit 190 and the fan 130. It is set in advance by experiments and simulations according to the air volume of the air flow to be performed, the assumed distance from the outlet 112 to the hair, and the like. Of course, the pattern of change with respect to the elapsed time is not limited to the example of FIG. 5, and may be a pattern of gradually increasing or interrupting for a certain period of time. Further, the dual ion mode is not limited to the case where the single ion mode is executed at the same time, and the optimum pattern may be set for the dual ion mode. The same applies to the pattern of change in the following description.

FIG. 6 is a diagram showing a second example of adjusting the amount of ions generated with respect to the usage time. In FIG. 6, the solid line shows a predetermined target amount of negative ions generated in warm air, and the alternate long and short dash line shows a predetermined target amount of negative ions generated in cold air. In the second example, as shown in the figure, the pattern of change in the target generation amount is different depending on whether the hot / cold switch 171 is set to the hot air mode or the cold air mode. ..

When the control unit 200 confirms that the negative ion mode and the warm air mode are selected with reference to the setting unit 202, the target generation at the time of warm air shown by the solid line according to the elapsed time measured by the time measuring unit 201 The on-duty ratio of the negative ion generation circuit 192 is adjusted so as to reach the quantity. Specifically, the target amount is adjusted from the start of use to time _t1 , which is _a relatively large amount, and the target amount is gradually reduced from _{time t1} to t2, and relatively after _time t2. Adjust a small amount of _Irh- as a target amount.

When the control unit 200 confirms that the negative ion mode and the cold air mode are selected with reference to the setting unit 202, the target generation amount at the time of cold air indicated by the alternate long and short dash line according to the elapsed time measured by the time measuring unit 201. The on-duty ratio of the negative ion generation circuit 192 is adjusted so as to reach. Specifically, I _sc- , which is a relatively large amount from the start of use to time t ₁ but is smaller than I _sh- during warm air, is adjusted as the target amount, and from time t ₁ to t ₂ The target amount is gradually reduced, and after time t2, _Irc- , which is a relatively small amount and smaller than _Irh- during warm air, is _adjusted as the target amount.

By adjusting in this way, when the same amount of ions is generated, the amount of ions that reach the hair in warm air is smaller than that in cold air, whereas the ions that are comparable to those in cold air are produced even in warm air. Can reach the hair. On top of that, since the amount of generation is changed according to the elapsed time, for example, excess ions do not reach the hair. Although the target generation amount of negative ions has been described in the second example, the target generation amount of positive ions can be set in the same manner.

FIG. 7 is a diagram showing a third example of adjusting the amount of ions generated with respect to the usage time. FIG. 7 shows the target generation amount when the negative ion mode is set, the solid line is the predetermined target generation amount of negative ions, and the dotted line is the predetermined target generation amount of positive ions. In the third example, as shown in the figure, even when the negative ion mode is set, positive ions are also generated from a certain point in time.

When the control unit 200 confirms that the negative ion mode is selected with reference to the setting unit 202, the control unit 200 may reach the target amount of negative ions generated by the solid line according to the elapsed time measured by the time measuring unit 201. In addition, the on-duty ratio of the negative ion generation circuit 192 is adjusted. Specifically, _Is- , which is a relatively large amount from the start of use to time t ₁ , is adjusted as the target amount, the target amount is gradually reduced from time t ₁ to t ₂ , and relatively after time t ₂ . Adjust a small amount of _Ir- as the target amount. Then, the control unit 200 adjusts the _{on -} duty ratio of the positive ion generation circuit 191 from time t5 to gradually generate positive ions, and after time t6, a constant amount _{Ip +} which is a smaller amount than _Ir− . Is adjusted as the target amount. By adjusting in this way, the negative ions on the hair, which may be excessive, are positively neutralized, and the positive ions are also given to the hair, so that a more preferable effect can be expected as a whole.

FIG. 8 is a diagram showing a fourth example of adjusting the amount of ions generated with respect to the usage time. FIG. 8 shows the target generation amount when the positive ion mode is set, the dotted line is a predetermined target generation amount of positive ions, and the solid line is a predetermined target generation amount of negative ions. In the fourth example, as shown in the figure, even when the positive ion mode is set, negative ions are also generated from a certain point in time.

When the control unit 200 confirms that the positive ion mode is selected with reference to the setting unit 202, the control unit 200 may reach the target amount of positive ions generated by the dotted line according to the elapsed time measured by the time measuring unit 201. In addition, the on-duty ratio of the positive ion generation circuit 191 is adjusted. Specifically, Is ₊ , which is a relatively large amount from the start of use to time t3 _, is adjusted as the target amount, the target amount is gradually reduced from time _t3 to _{t4 ,} and a relatively small amount after time t4. Ir ₊ is adjusted as the target amount. Then, the control unit 200 adjusts the on-duty ratio of the negative ion generation circuit 192 from time _t7 before time t3 to gradually generate negative ions, and after time _{t8 ,} a larger amount than Ir ₊ . A certain amount I _p- is adjusted as a target amount. In this way, negative ions, which are said to have a large effect on dry hair, are gradually generated before the positive ions are gradually reduced, and after the time when drying is expected to be completed, more negative ions are generated than positive ions. You may let me.

FIG. 9 is a diagram showing a fifth example of adjusting the amount of ions generated with respect to the usage time. FIG. 9 shows the target generation amount when the negative ion mode is set, the solid line is the predetermined target generation amount of negative ions, and the dotted line is the predetermined target generation amount of positive ions. As shown in the figure, the fifth example differs from the third example in that positive ions are also generated from the start of use.

From the first example to the fourth example, the pattern of the change in the target generation amount is different in consideration of the effect on the hair, but in the fifth example, the pattern is different depending on the device configuration of the hair dryer. An example is shown. In the above-mentioned ion generation circuit 190, the blowout grill 160 is used as a counter electrode and the blowout grill 160 is connected to the ground wire, but a configuration in which the blowout grill 160 is not connected to the ground wire can also be adopted. In this case, if the ion of one pole is continuously generated, the blowout grill 160 is charged with the electric charge of the pole, and eventually the discharge becomes extremely difficult to occur. Therefore, in the fifth example, positive ions (target amount I _{w +} ) that neutralize the negative ions charged in the blowout grill 160 are generated from the start of use so that the generation of negative ions can be continued. .. Although the example of the negative ion mode has been described in the fifth example, when the configuration in which the blowout grill 160 is not connected to the ground wire is adopted, negative ions are similarly generated from the start of use even in the positive ion mode. ..

Next, a modified example of adopting the ion generation circuit 190', which has a circuit configuration slightly different from that of the ion generation circuit 190, will be described. FIG. 10 is a diagram showing an outline of the ion generation circuit 190 ′ according to the modified example. In the above-mentioned ion generation circuit 190, the three negative ion electrodes 151a, 151b, and 151c were trifurcated electrodes. Therefore, these electrodes are controlled by one negative ion generation circuit 192 and simultaneously generate negative ions. The negative ion electrodes 151a, 151b, and 151c related to the ion generation circuit 190'are independent of each other. Then, each is connected to a separate negative ion generation circuit 192a, 192b, 192c. The control unit 200 can generate negative ions from the respective electrodes at arbitrary timings by sending separate control signals to the negative ion generation circuits 192a, 192b, and 192c.

FIG. 11 is a diagram showing a sixth example of adjusting the amount of ions generated with respect to the usage time when the ion generation circuit 190'of FIG. 10 is adopted. FIG. 11 shows the target generation amount when the negative ion mode is set.

When the control unit 200 confirms that the negative ion mode is selected with reference to the setting unit 202, the control unit 200 may reach the target amount of negative ions generated by the solid line according to the elapsed time measured by the time measuring unit 201. In addition, the on-duty ratio of the negative ion generation circuit 192 is adjusted. Specifically, from the start of use to time _t7 , negative ions are generated from all of the negative ion electrodes 151a, 151b, 151c with a relatively large amount of I _al- as a target amount. Then, from time _{t7 to t8, negative ions are generated from the negative ion electrodes 151a and 151c arranged on the left and right with Isd− as the} target generation amount. By selecting the electrodes in this way, negative ions can be distributed around the air flow, which makes it easier for the user to arrange the hair. Then, after the time, negative ions are generated from the negative ion electrode 151b arranged in the center with _Ict− as the target generation amount.

In the above, some patterns of changes in the target generation amount with respect to the elapsed time have been described, but of course, those that can be combined may be combined with each other. In addition, the pattern of change can be changed in various ways depending on the effect of interest, the request from the hardware configuration, and the like. When the hair dryer is provided with an operation member such as an ion adjustment dial, it may be controlled to correct the change pattern according to the operation amount operated by the user.

Further, in the ion generation circuit 190 described in the above embodiment, the amount of positive ions and negative ions generated is controlled by adjusting the on-duty of the supply power, but the control of the amount of generation is not limited to this method. .. The applied voltage may be controlled, or both the pulse width and the applied voltage may be controlled. In addition, the ion generation circuit is not limited to a circuit configuration in which a positive ion generation circuit and a negative ion generation circuit are provided in parallel and can generate ions of both poles at the same time, but also in a circuit configuration in which positive ions and negative ions are alternately generated. It doesn't matter if there is one. In this case, the target ion generation amount is managed as the ion generation amount per unit time.
