Description

  The present invention relates to a hair care device such as a hair dryer or a hair iron.

  Conventionally, as a hair care apparatus, there exists a thing described in Unexamined-Japanese-Patent No. 2009-254844 (patent document 1).

Electrons are emitted from the ion generator toward the air and bonded to massive water molecules to generate large mass negative ions.

JP 2009-254844 A

  However, since the conventional hair care device can generate only negative ions, the user's hair is negatively overcharged by the negative ions, and the negative ions to be supplied are negatively charged to the hair. Due to the repulsive force from the electric charge, there is a problem that negative ions and moisture accompanying the negative ions cannot be supplied to the hair.

  Therefore, an object of the present invention is to provide a hair care device that can prevent overcharging of hair and can sufficiently supply moisture to hair.

In order to solve the above problems, the hair care device of the present invention is:
A housing having an air outlet and a suction port;
A blower provided in the housing;
A heater provided in the housing;
An ion generator provided in the housing and capable of generating positive ions and negative ions;
An infiltration mode selection unit for selecting an operation of an infiltration mode that promotes infiltration of the positive ions and the negative ions into the hair generated by the ion generator;
When the permeation mode is selected by the permeation mode selection unit, the temperature of the air blown from the air outlet is generated by the ion generator while driving the ion generator and the blower. And a control unit that controls the positive ions and the negative ions to have a predetermined acceleration temperature at which penetration of the negative ions into the hair is promoted.

  According to the above configuration, since the ion generator capable of generating positive ions and negative ions is provided in the casing, both positive ions and negative ions are supplied to the user's hair, and the negative or negative ions are supplied to the user's hair. Only one positive charge does not accumulate excessively, and therefore, there is little repulsive force from charged hair, and positive and negative ions can be sufficiently supplied to the hair.

  Further, when the permeation mode operation that promotes permeation of positive ions and negative ions into the hair is selected by the permeation mode selection unit, the control unit determines that the temperature of the blown air from the outlet is positive ions and negative ions. The heater is controlled so as to achieve an acceleration temperature that promotes penetration into the hair. In this way, the temperature of the air blown from the outlet becomes the acceleration temperature, and the penetration of positive ions and negative ions generated by the ion generator into the user's hair is promoted. Moisture is sufficiently supplied to the hair to prevent keratin denaturation and the like, thereby greatly reducing damage to the hair.

In one embodiment of the hair care device,
The positive ion is H ⁺ (H ₂ O) _m (m is an arbitrary natural number), and the negative ion is O ₂ ⁻ (H ₂ O) _n (n is an arbitrary natural number).

According to the embodiment, the ion generator includes positive ions that are H ⁺ (H ₂ O) _m (m is an arbitrary natural number) and O ₂ ⁻ (H ₂ O) _n (n is an arbitrary natural number). Can produce negative ions. These positive ions and negative ions are attached to the surface of airborne bacteria in the air and chemically react to generate H ₂ O ₂ or .OH (hydroxyl radical) which is an active species. Since this H ₂ O ₂ or .OH exhibits extremely strong activity, it can be inactivated and removed by surrounding mold and bacteria that are airborne bacteria.

In one embodiment of the hair care device,
The acceleration temperature has an upper limit of 55 ° C.

  According to the above embodiment, since the accelerating temperature when the permeation mode is selected is 55 ° C., it is possible to more reliably promote the penetration of moisture accompanying positive ions and negative ions into the hair, and hair. Keratin degeneration can be suppressed.

In one embodiment of the hair care device,
The accelerated temperature is 38 ° C to 55 ° C.

  According to the embodiment, since the accelerating temperature when the permeation mode is selected is 38 ° C. to 55 ° C., it is possible to further reliably promote the penetration of moisture accompanying positive ions and negative ions into the hair, This is preferable because it does not take heat away from the body.

In one embodiment of the hair care device,
The hair care device is a hair dryer.

  According to the above-described embodiment, during use, the hair is prevented from being charged with only one positive or negative charge, and the penetration of moisture accompanying positive and negative ions into the hair is promoted, resulting in significant damage to the hair. A hair dryer that can be reduced can be realized.

  As is clear from the above, according to the hair care device of the present invention, since positive and negative ions can be generated, it is possible to prevent excessive charging of only positive or negative charges on the hair during use, and further, the blown air Is controlled to a temperature that promotes the penetration of moisture associated with positive and negative ions into the hair, so that sufficient moisture is supplied to the hair to prevent keratin denaturation. Damage can be greatly reduced.

  Hereinafter, the hair care device of the present invention will be described in detail with reference to embodiments shown in the drawings.

  As shown in FIG. 1, the hair dryer of this embodiment includes a housing 1, a handle 2, and an intake filter 3.

As shown in FIG. 2, the intake filter 3 is provided with a plurality of mesh-shaped holes, and the plurality of mesh-shaped holes form a suction port 12. The intake filter 3 prevents large foreign matters such as dust from entering the housing 1 and also causes a finger to accidentally enter the air passage 8 during operation, so that the blower fan 6 (see FIG. 3) is an example of a blower. ) Is protected from touching.

  FIG. 3 is a longitudinal sectional view of the hair dryer as seen from line III-III in FIG. 2 and 3, the power cord 4 shown in FIG. 1 is omitted.

  The blower fan 6 is disposed substantially at the center inside the housing 1 and generates a flow of air flowing from the suction port 12 to the blower outlet 11. The air heated by the heaters 5 and 5 is blown out of the housing 1 from the air outlet 11 by the air flow generated by the blower fan 6.

The ion generator 7 is provided at the bottom of the housing 1 on the suction port 12 side, and is disposed between the intake filter 3 and the blower fan 6. The ion generator 7 generates positive ions that are H ⁺ (H ₂ O) _m (m is an arbitrary natural number) and negative ions that are O ₂ ⁻ (H ₂ O) _n (n is an arbitrary natural number). discharge. These ions adhere to the surface of airborne bacteria in the air and chemically react to generate H ₂ O ₂ or .OH (hydroxyl radical) which is an active species. Since H ₂ O ₂ or .OH shows extremely strong activity, it can be inactivated and removed by surrounding mold and bacteria that are airborne bacteria.

  Further, inside the handle 2, a power supply unit 23, heaters 5, 5, a blower fan 6, and a control unit 22 (not shown) that controls the ion generator 7 are provided.

  FIG. 4 is a perspective view when the hair dryer from which the intake filter 3 is removed is viewed from the inlet 12 side.

  As shown in FIG. 4, the ion generator 7 is provided on the suction port 12 side and the lower side of the housing 1, and is fitted into a recess (not shown). Since the ion generator 7 can be easily removed from the recess, maintenance of the ion generator 7 and the like can be easily performed.

  Moreover, the latching | locking part 14 is provided in the suction inlet 12 side and the upper side of the said housing | casing 1. FIG. The intake filter 3 is locked to the housing 1 by the locking portion 14.

  FIG. 5 is a perspective view of the ion generator 7 as viewed from the surface facing the air outlet 11.

  As shown in FIG. 5, the ion generator 7 includes a positive ion generator 15 that generates positive ions and a negative ion generator 16 that generates negative ions. The positive ion generator 15 and the negative ion generator 16 are provided at a predetermined interval on the surface facing the air outlet 11 when the ion generator 7 is attached to the housing 1.

  The positive ion generator 15 includes a needle-shaped needle electrode 25 having a sharp tip, and a donut disk-shaped induction electrode 35 disposed so as to surround the needle electrode 25. The needle electrode 25 is positioned substantially at the center of the induction electrode 35, and the interval between the needle electrode 25 and the inner peripheral edge of the induction electrode 35 is 8 mm.

  On the other hand, the negative ion generator 16 also has a needle-shaped needle electrode 26 with a sharp tip, and a donut disk-shaped induction electrode 36 arranged so as to surround the needle electrode 26. The needle electrode 26 is located substantially at the center of the induction electrode 36, and the interval between the needle electrode 26 and the inner peripheral edge of the induction electrode 36 is 8 mm.

  Next, the operation of the hair dryer will be described. In the hair dryer having the above-described configuration, first, the operation unit 21 on the handle 2 is operated. By operating the operation unit 21, it is possible to switch between the “normal mode” and the “penetration mode” as well as switching the hair dryer on and off. The normal mode refers to a mode in which the hair dryer is operated so that the temperature of the blown air from the blower outlet 11 is about 130 ° C., and the infiltration mode refers to the temperature of the blown air from the blower outlet 11 becomes about 50 ° C. The mode that drives the hair dryer.

  In addition, in this specification, the temperature of the air blown from the blower outlet 11 means the temperature of the blown air measured by the method prescribed | regulated by JISC9613 (7.6.1 normal temperature experiment).

  When the user operates the operation unit 21 to select a desired mode, as shown in FIG. 6, power from the power supply unit 23 is supplied to the control unit 22, and at the same time the control unit 22 is in an operating state, A signal corresponding to the mode selected in 21 is sent to the control unit 22. Based on the signal, the control unit 22 transmits a control signal from the control unit 22 to the power control switch units 27 and 28 of the heaters 5 and 5. Then, power is supplied to the heaters 5 and 5 through the power control switch units 27 and 28, and the heaters 5 and 5 are put into an operating state.

  The control unit 22 controls the heaters 5 and 5 independently. That is, only one heater 5 can be driven, or two heaters 5 and 5 can be driven simultaneously. Therefore, the blowout temperature from the blower outlet 11 can be freely adjusted by the number of heaters 5 and 5 to be driven. The control unit 22 controls to drive both of the two heaters 5 and 5 in the normal mode, and controls to drive only one heater 5 in the permeation mode.

  Further, as shown in FIG. 7, the control unit 22 transmits a control signal to the blower fan 6 and the ion generator 7 at the same time so as to be in an operating state. The blower fan 6 in the operating state is controlled to blow a predetermined air volume, and forms a flow of air flowing from the suction port 12 to the blower port 11.

On the other hand, the ion generator 7 in the operating state energizes both the positive ion generation unit 15 and the negative ion generation unit 16, and is a positive ion that is H ⁺ (H ₂ O) _m (m is an arbitrary natural number). And negative ions which are O ₂ ⁻ (H ₂ O) _n (n is an arbitrary natural number) are generated simultaneously.

At this time, in the positive ion generator 15 of the ion generator 7, for example, a 60 Hz alternating current in which a voltage of effective voltage 2 kV or higher and 0 V are switched is applied to the needle electrode 25, while 0 V is applied to the induction electrode 26. The direct current is applied. When an effective voltage of 2 kV or more is applied to the needle electrode 25, a corona discharge due to a potential difference with the induction electrode 26 occurs, and water molecules in the air are ionized near the tip of the needle electrode 25 to generate hydrogen ions ( H ⁺ ) is produced. The hydrogen ions are combined (clustered) with water molecules in the air in a group state, and positive ions composed of H ⁺ (H ₂ O) m (m is an arbitrary natural number) are generated.

On the other hand, in the negative ion generator 16 of the ion generator 7, for example, a voltage of effective voltage −2 kV or less and an alternating current of 60 Hz that switches 0 V are applied to the needle electrode 35, while 0 V is applied to the induction electrode 36. In this way, negative ions are generated. The negative ions are oxygen ions O ₂ ^{− formed} by ionization of oxygen molecules or water molecules in the air. The oxygen ions are combined (clustered) with water molecules in the air to generate negative ions composed of O ₂ ⁻ (H ₂ O) n (n is an arbitrary natural number).

  Positive ions and negative ions generated by the ion generator 7 are released from the ion generator 7 into the housing 1 and ride on the air flow formed by the blower fan 6. It is blown out to the outside and supplied to the user's hair. Therefore, since both positive ions and negative ions are supplied to the user's hair at the same time, there is no excessive accumulation of only one negative or positive charge in the user's hair, and thus the repulsive force from the charged hair The amount of positive and negative ions can be sufficiently supplied to the hair.

  By the way, in the positive ions and the negative ions, hydrogen ions and oxygen ions are surrounded by a plurality of water molecules. If the temperature of the air blown from the air outlet 11 is too high, positive ions and negative ions are activated, and water molecules around hydrogen ions and oxygen ions are considered to decrease. Therefore, positive ions and negative ions are easily bonded to each other and disappear, and the amount of ions sprayed on the user's hair is reduced.

  This was discovered by the following experiment. In the following experiment, the temperature of the air blown from the air outlet 11 is set to the cool mode, the set hair care mode, the dry hair care mode, the set mode, and the dry mode in order from the lowest to the highest. Also, by turning off the turbo, the air volume of the blown air is set to the normal air volume, while by turning on the turbo, the air volume of the blown air is increased by about 15% from the normal air volume.

  FIG. 9 shows changes in the ion concentration of each mode in the first test machine with the turbo turned off. FIG. 10 shows a graph in which the ion concentration is plotted in the cool mode, the dry mode, and the dry hair care mode in which the air volume is comparable based on FIG.

  In FIG. 10, the horizontal axis represents the temperature of the blown air, and the vertical axis represents the ion concentration. In FIG. 10, the rhombus indicates the positive ion concentration, the square indicates the negative ion concentration, and the triangle indicates the total ion concentration of the positive ion concentration and the negative ion concentration. In FIG. 10, the modes of the same air volume are compared. This is because the ion concentration increases as the air volume increases. Since ions are generated and disappear by neutralization at the same time, they can be taken out before neutralization by blowing with a fast wind, and the amount of ions increases. From FIG. 10, it was found that there was a maximum value in the amount of positive ions and negative ions (ion concentration) with respect to the temperature of the blown air.

  Similarly, FIG. 11 shows the change in ion concentration in each of the above modes with the turbo turned on in the first test machine. FIG. 12 shows a graph in which ion concentrations are plotted in the cool mode, the dry mode, and the dry hair care mode in which the air volume is comparable based on FIG.

  In FIG. 12, the rhombus indicates the positive ion concentration, the square indicates the negative ion concentration, and the triangle indicates the total ion concentration of the positive ion concentration and the negative ion concentration. From FIG. 12, it was found that there was a maximum value in the amount of positive ions and negative ions (ion concentration) with respect to the temperature of the blown air.

  Further, FIG. 13 shows the change in ion concentration in each of the above modes with the turbo turned off in the second test machine. And based on FIG. 13, the graph which plotted the ion concentration in the cool mode, dry mode, and dry hair care mode used as the same air volume is shown in FIG. Note that different ion generators 7 are used in the first test machine and the second test machine.

  In FIG. 14, the rhombus indicates the positive ion concentration, the square indicates the negative ion concentration, and the triangle indicates the total ion concentration of the positive ion concentration and the negative ion concentration. From FIG. 14, it was found that there was a maximum value in the amount of positive ions and negative ions (ion concentration) with respect to the temperature of the blown air.

  Similarly, FIG. 15 shows changes in ion concentration in each of the above modes with the turbo turned on in the second test machine. FIG. 16 shows a graph in which the ion concentration is plotted in the cool mode, the dry mode, and the dry hair care mode in which the air volume is comparable based on FIG.

  In FIG. 16, the rhombus indicates the positive ion concentration, the square indicates the negative ion concentration, and the triangle indicates the total ion concentration of the positive ion concentration and the negative ion concentration. From FIG. 16, it was found that there was a maximum value in the amount of positive ions and negative ions (ion concentration) with respect to the temperature of the blown air.

  From FIG. 10, FIG. 12, FIG. 14, and FIG. 16, if the ion amount increasing temperature range that is the maximum value or the range near the maximum value is 50 ° C. to 100 ° C., the amount of positive ions and negative ions of the ions It turns out that we can definitely increase

  On the other hand, when the temperature of the air blown from the air outlet 11 is lowered, the ionization of water molecules due to discharge does not proceed, and as a result, the amount of ions sprayed on the user's hair is considered to decrease.

  Moreover, when hair exceeds about 55 ° C., keratin may begin to denature. The hair is damaged by the modification of keratin in the hair.

  Therefore, in order to promote the penetration of moisture accompanying positive ions and negative ions into the hair, it is preferable to set the blowing temperature of the blower outlet 11 to a temperature within a certain range (hereinafter referred to as an accelerating temperature). This accelerated temperature is 38 ° C to 55 ° C. A temperature of 38 ° C. is preferable because it does not take the heat of the body.

  In this experiment, first, about 5 g of a dried hair bundle left on a desiccator containing a desiccant was suspended and a dryer was blown from above 15 cm. After 15 minutes, the hair bundle was brushed 10 times with a PP brush, and the charged potential of the hair bundle was measured. The results are shown in Table 1 and FIG.

  When the hair dryer is used, when the operation unit 21 selects the operation in the permeation mode that promotes the penetration of moisture associated with positive ions and negative ions into the hair, the control unit 22 blows out from the air outlet 11. The heaters 5 and 5 are controlled so that the temperature of the air becomes an acceleration temperature at which penetration of positive ions and negative ions into the hair is promoted. As described above, the temperature of the air blown from the outlet 11 becomes the acceleration temperature, and the penetration of positive ions and negative ions generated by the ion generator 7 into the user's hair is promoted. Moisture accompanying the hair is sufficiently supplied to the hair, preventing keratin denaturation and the like and greatly reducing damage to the hair.

  In the above embodiment, the permeation mode and the normal mode are switched by the operation unit 21, but an independent permeation mode selection button for selecting the permeation mode may be provided. Further, by operating the operation unit 21, the rotational speed of the blower fan 6 can be adjusted in a plurality of stages (for example, two stages of “strong” and “weak”) so that the strength of the blown air can be adjusted. Also good. Alternatively, the heaters 5 and 5 may be turned on / off so that it is possible to appropriately select whether to blow cold air or hot air.

  In the above embodiment, the two heaters 5 and 5 are provided. However, the present invention is not limited to this. For example, three or more heaters 5 may be provided, or only one heater may be provided.

  In the said embodiment, although the temperature of the blowing air from the blower outlet 11 is adjusted by adjusting the number of the heaters 5 and 5 to drive, for example, a temperature detection part is provided around the blower outlet 11, and blown air The temperature may be measured. When the temperature of the blown air detected by the temperature detector reaches a certain value, the power to the heaters 5 and 5 is cut off. When the temperature of the blown air falls below a certain value, the power to the heaters 5 and 5 is cut off. By controlling so that the air is supplied, the temperature of the air blown from the air outlet 11 can be adjusted more accurately and freely.

In the above embodiment, positive ions that are H ⁺ (H ₂ O) _m (m is an arbitrary natural number) and negative ions that are O ₂ ⁻ (H ₂ O) _n (n is an arbitrary natural number) are generated. Although the ion generator 7 is provided, the present invention is not limited to this, and a simple positive ion and negative ion may be generated.

  In the above embodiment, both the positive ion generation unit 15 and the negative ion generation unit 16 of the ion generator 7 are driven simultaneously. However, the present invention is not limited to this, and only the positive ion generation unit 15 or the negative ion generation unit 16 is driven. It may be possible to drive only. With this configuration, the user appropriately selects ions to be blown out from the blowout port 11 so as to be only positive ions, only negative ions, or both positive ions and negative ions by operating the operation unit 21. can do.

  In the above embodiment, the ion generator 7 may be configured so that the amount of ions per unit time generated by the positive ion generating unit 15 and the negative ion generating unit 16 can be changed as appropriate, or cannot be changed. It may be.

  In the above embodiment, the present invention has been described by taking a hair dryer as an example. However, the hair care device of the present invention is not limited to a hair dryer, and may be, for example, a hair iron or a roll brush, and can discharge air. Any device that can be used for hair care may be used.
