Abstract

In the present invention, an air intake filter (3), fan (6), and heater (11) are arranged within a frame (2), and an ion generator (5) is arranged between the air intake filter (3) and the fan (6). This causes dust to be less prone to adhere to the fan (6) due to electrostatic charge. Masses of dust having adhered to the fan (6) are also prevented from flowing downstream, adhering to the heater (11), and causing a fire outbreak triggered by electrical discharge; further, the adherence of the masses of dust to hair is also suppressed.

Description

Hair dryer

The present invention relates to a hair drier that can perform hair treatment by blowing hot air to blow and set hair and blowing air containing ions.

Conventionally, hair dryers that can not only dry and set hair by discharging warm air but also perform hair treatment by blowing air containing ions are used.

For example, Patent Document 1 discloses a hair dryer provided with a fan for blowing air, an ion generator for generating ions, a heater, and the like in a housing. The hair dryer warms the air blown from the fan with a heater, and sends the warm air to the outside from the air discharge port of the housing to dry the hair. At that time, the hair may be charged by brushing or the like. For this reason, an ion generator is arranged downstream of the fan to generate an ion wind and hit the hair to prevent the generation of static electricity.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.

(Dryer configuration)
1 is a side perspective view showing an internal configuration of a hair dryer according to Embodiment 1 of the present invention, and FIG. 2 is a rear perspective view.

The hair dryer 1 has an exterior composed of a housing 2, an intake filter 3 on the air suction side of the housing 2, a handle 4 attached to the housing 2, and a nozzle 13. The housing 2, the intake filter 3, the handle 4, and the nozzle 13 may be integrally formed.

Inside the housing 2, an ion generator 5 for generating ions, a fan 6 for blowing air, a motor and wiring (not shown) for driving the fan 6, a partition plate 10, and a heater 11 are provided.

Here, the intake filter 3 side (right side in FIG. 1) of the housing 2 is referred to as the upstream side, and the discharge port 12 side (left side of FIG. 1) from the fan 6 is referred to as the downstream side. In addition, on the basis of a certain part, it is called that the air flow is located upstream from the upstream side. For example, the fan 6 is located upstream of the air flow path 7.

The case 2 will be described. It is made of plastic, and a mica film is stuck inside to enhance heat resistance. The housing 2 has a hollow inside so that air can flow. The housing 2 has an air inlet at one end of the housing 2 to which the intake filter 3 is attached, and the other end is an outlet 12 through which air is discharged. A metal filter is usually attached to the discharge port 12 in many cases.

The intake filter 3 is made of metal or plastic and has holes in a mesh shape or a lattice shape. The intake filter 3 serves to protect large foreign objects such as dust from entering, and to prevent a finger from touching the fan 6 accidentally during operation. Here, the intake filter 3 is attached to the housing 2 so as to be detachable from the housing 2.

The handle 4 is made of plastic and is provided with a switch 14. When the switch 14 on the handle 4 is operated to bring the hair dryer 1 into an operating state, the ion generator 5, the fan 6, and the heater 11 are operated. By operating the switch 14, for example, it is possible to switch to a mode according to the application such as a high-temperature air mode suitable for drying hair, a low-temperature air mode suitable for styling, and a ventilation mode for blowing only the wind. The heater 11 does not operate in the air blowing mode.

The ion generator 5 is disposed on the upstream side of the housing 2, specifically, is disposed between the intake filter 3 and the fan 6. Further, the ion generator 5 is disposed above the center line of the fan 6. The ion generator 5 generates ions, and at the same time, may generate ions in a state where ions and water molecules are bonded. Demonstrates the effect of neutralizing and moisturizing hair with ions and water molecules bonded to ions.

The fan 6 takes air into the housing 2 through the intake filter 3 and sends it out from the discharge port 12 of the housing 2. The fan 6 is made of polypropylene. Air blown from the fan 6 passes through the air flow path 7. The air flow path 7 is divided into an upper air flow path 8 and a lower air flow path 9 by a partition plate 10 made of mica. The air passing through the lower air flow path 9 is warmed by the heater 11 and sent out as warm air. The air passing through the upper air flow path 8 is sent out without passing through the heater 11. The air that has passed through the upper and lower air channels exits the discharge port 12 and is sent out from the tip of the nozzle 13.

In this way, hot air and normal air (cold air) are mixed and blown, so that the heat of the hot air breaks the hydrogen bond of the hair and stretches the hair, and when cold air is applied immediately after that, the hair is again Since hydrogen bonding occurs, the hair can be fixed in a stretched state, and hair styling can be improved.

The nozzle 13 is made of plastic, has a trapezoidal cross-sectional shape, has a wide discharge port side, and the other end is narrow. The nozzle 13 rectifies so that the air discharged from the discharge port 12 does not spread.

As in the present embodiment, it is desirable that the intake area of the intake filter 3 is larger than the inner dimension of the air flow path 7. Thereby, a faster wind can be blown to the outside of the hair dryer 1.
(Ion generator)
Next, the ion generator 5 will be described in detail.

FIG. 3 is a perspective view of the ion generator 5. The ion generator 5 has two ion generating parts each composed of a needle electrode 15 and an induction electrode 16. In each ion generating part, the needle electrode 15 has a needle shape with a pointed tip, and a circular induction electrode 16 is arranged so as to surround the periphery of the needle electrode 15, and the distance between both electrodes is 8 mm.

For example, a voltage of effective voltage +2 kV or higher and 60 Hz alternating current that switches 0 V are applied to the needle electrode 15, and ions are generated by applying 0 V direct current to the induction electrode 16. When an effective voltage of +2 kV or more is applied to the needle electrode 15, corona discharge occurs due to a potential difference with the induction electrode 16, and water molecules in the air are ionized near the tip of the needle electrode 15 to generate hydrogen ions (H ⁺ ) Is generated. The hydrogen ions are combined (clustering) with water molecules in the air in a group state (clustering), and positive ions composed of H ⁺ (H ₂ O) m (m is an arbitrary natural number) are generated.

Further, a negative ion is generated by applying a 60 Hz alternating current at which effective voltage −2 kV or less and 0 V are switched to the needle electrode 15 and applying a direct current of 0 V to the induction electrode 16. The negative ions are ionized by oxygen molecules or water molecules in the air to generate oxygen ions O ₂ ⁻ . 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). In the present invention, the ion generator may generate ions that do not bind to water molecules.

Here, the ion generator 5 has two ion generation units, and each ion generation unit is a positive ion generation unit and a negative ion generation unit. Therefore, positive ions and negative ions are released at the same time, and flow downstream through the air flow created by the fan 6.

As shown in FIG. 3, the ion generator 5 is arranged so that the ion generators are arranged side by side. The

electrodes

15 and 16 are arranged on the fan 6 side. Originally, the

electrodes

15 and 16 are preferably arranged in a direction perpendicular to the airflow. This is because the ion generator is not preferable because the ion generation surface with electrodes is horizontally long and the depth in the direction of the needle electrode 15 is long, as shown in FIG. 3, so that the intake port (intake filter 3) is blocked.

4A to 4C are diagrams showing the arrangement of ion generators that can be taken in the present invention, and the amount of ions generated from the discharge port 12 was examined in the three arrangements shown in FIGS. 4A to 4C. Table 1 shows the amount of ions generated.

When the electrodes are arranged in the direction orthogonal to the wind flow indicated by the arrows as shown in FIG. 4A, ions from 550,000 / cc to 1.2 million / cc are emitted as shown in Table 1. The ion concentration in the blown air is the highest. Here, the experiment was performed in two states: a normal air flow rate (NORMAL) and a state where the air flow rate is large (air blowing is fast) (TURBO). In the figure, the electrode is facing downward, but the same result can be obtained even when facing upward.

In FIG. 4B, the electrodes are arranged in the leeward direction with respect to the direction of the wind. Even in this case, ions of 900,000 / cc to 1.1 million / cc are emitted, and ions having no practical problem are discharged from the discharge port 12.

Further, in FIG. 4C, the electrodes are arranged on the windward side with respect to the wind direction. Even in this case, ions of 950,000 / cc to 1,050,000 / cc are emitted, and ions having no practical problem are discharged from the discharge port 12.

In this way, a sufficient amount of ions can be obtained regardless of the amount of ions to be exhaled. Therefore, the amount of blown air is not reduced by being blocked by the suction port of the ion generator 5 as shown in FIG. 4B or 4C. It is preferable to arrange in such a manner. In particular, the arrangement shown in FIG.

In addition, it is desirable that the positive ions and negative ions to be discharged are almost the same number or more negative ions. If the number of positive ions and negative ions is balanced, the probability that OH radicals are generated increases. When the hair is not balanced, the hair is positively charged, and therefore, more negative ions are preferable because the hair can be prevented from being squeaked or damaged.

In a hair dryer equipped with a conventional ion generator, the ion generator is provided in a dedicated passage as in Patent Document 1, and the dedicated passage is a narrow passage that restricts the amount of air sent, However, it was weak and difficult to reach the hair. Further, in the configuration as in Patent Document 1, since the original wind of the dryer is hot and the air volume is strong, it is often not known that the weak wind coming out from the ion passage really hits the hair, and in many cases it does not actually hit the hair. It was. However, according to the present invention, since the same wind as the other wind is used instead of the ion-only wind, the user notices whether the ion wind is applied to the hair. Therefore, the ion can be used while being appropriately applied to the hair and scalp, so that the effect of the ion is easily exhibited.

Moreover, as can be seen from Table 1, if the air volume increases, the generated ions can be effectively removed from the hair dryer, so the effect is stronger when the hair is dried using a strong air like a salon. Will be able to exert a moist squeaky and brutal salon blow effect at home.

The ions blown downstream are blown to the hair via the discharge port 12 and the nozzle 13. Since hair is easily charged positively by brushing, negative ions can prevent static electricity and improve hair damage. In addition, it is possible to prevent generation of static electricity in the brush charged negatively by positive ions and improve hair damage. In addition, by applying ions bound to water molecules to the hair, moisture can penetrate into the hair with small water molecules at the nano and micro levels, and moist hair can be obtained.

When the ion generator 5 of this embodiment is used, positive ions and negative ions adhere to the scalp and both react to form OH radicals. The OH radicals oxidize the remaining shampoo and rinse residue on the scalp, which prevents hair growth, breaking the double bond. This can help make the scalp optimal for hair growth. Since OH radicals are unstable, they can exist only in nanosecond units. Therefore, even if OH radicals are produced by the ion generator 5, they disappear before reaching the scalp. However, as in the present embodiment, positive ions and negative ions are produced in the ion generating portion, and both are reacted in the scalp, so that OH radicals can be effectively produced in the scalp. Moreover, OH radical also has a sterilization and deodorizing effect.

In this embodiment, the ions generated from the ion generator 5 are sucked into the fan 6 at the same time. Since the fan 6 rotates at a high speed, static electricity is generated due to friction with the air, and dust is easily attached. In particular, small dust that passes through the intake filter 3 is easily sucked by static electricity. However, by disposing the ion generator 5 on the upstream side between the intake filter 3 and the fan 6 as in this embodiment, the charge of the fan 6 is reduced by the ions generated by the ion generator 5, and the fan 6 can be reduced from dust. Thereby, the fan 6 can be kept clean. Further, it is possible to prevent a problem that a lump of dust adhering to the fan 6 flows downstream, adheres to the heater and causes discharge, and a problem that a lump of dust adheres to the hair.

For example, when a fan 6 made of polypropylene or polycarbonate is used, it is easy to be negatively charged. Therefore, charging is prevented by wind containing positive ions, and dust adhesion due to static electricity can be reduced. In this embodiment, it is not only the fan 6 that can prevent charging. The mica film inside the housing 2 and the plate around which the heater is usually wound are made of mica, and these are easy to be positively charged. Dust adhesion due to can be reduced. Further, when ions combined with water molecules are used as in this embodiment, generation of static electricity can be suppressed by the water molecules.

When only negative ions or positive ions are used, the filter provided at the discharge port 12 may be charged and ions may be difficult to be emitted, but such a phenomenon can be prevented by positive and negative ions.

Since the ion generator 5 is disposed at a position far from the heater 11, it is possible to prevent the ion generator 5 from malfunctioning or failing due to the heat of the heater 11.

When a fan 6 that uses a rotating fan such as a propeller fan is used as the fan 6, if the ion generator 5 is arranged downstream of the fan 6, the rotating wind is sent immediately after the ions are generated. There is a problem that the amount of ions that are neutralized and go out of the hair dryer 1 is reduced. However, by arranging it upstream of the fan 6 as in the present embodiment, relatively parallel wind comes into contact with the ion generator 5 and neutralization immediately after the generation of ions is prevented. Once the air is blown in a state where it is separated into positive ions and negative ions, the separated state continues and it becomes difficult to neutralize even if it becomes a swirl wind, so the amount of ions that go out of the hair dryer 1 can be increased. it can.

It is desirable that the positive ion ion generating part and the negative ion generating part of the ion generator 5 be arranged about 1/2 the diameter of the fan. In particular, the positive ion generator and the negative ion generator of the ion generator are preferably separated by about 20 mm or more in a direction orthogonal to the direction of the wind. Thereby, the neutralization of positive ions and negative ions can be reduced immediately after the generation of ions.

When using an ion generator that utilizes water molecules in the air as in the present embodiment, rather than placing it in a narrow air flow path as in Patent Document 1, it is on the intake side (upstream side) that inhales a large amount of air. By providing, water molecules in the air can be used effectively, and a large number of ions and ions bonded to the water molecules can be generated. For this reason, the effect of preventing the static electricity generation of the fan 6 and the like and the prevention of the static electricity generation of the hair are improved.

When the air flow path 7 is divided into upper and lower portions as in the present embodiment, ions that do not pass through the heater 11 can be extracted from the discharge port 12, so that water is heated by heat particularly when ions combined with water molecules are used. This is effective because it can prevent the molecule from being broken. In particular, when the upper air flow path 8 and the ion generator 5 are arranged substantially in parallel as in the present embodiment, it is effective because more air can be blown out of the hair dryer 1 by the upper air flow path 8. It is.

FIG. 5 is a front view of a hair dryer according to Embodiment 2 of the present invention. In the second embodiment, not only the air flow path 7 is divided into the upper air flow path 8 and the lower air flow path 9 by the partition plate 10, but the upper air flow path 8 is divided into the upper left air flow path 8a and the upper right air flow path. Separated into 8b. Others are the same as in the first embodiment. In this way, by changing the shape of the partition plate 10, the positive ions and negative ions generated by the ion generator 5 are less likely to be mixed in the air flow path 7, and the amount of ions leaving the hair dryer 1 is increased. Can do. In addition, the partition plate 10 can be made by a separate member other than the integrally formed plate.

In this third embodiment, unlike the first and second embodiments, an ion generator 5 having only a negative ion generation section (without a positive ion generation section) was used. Further, as the fan 6, an engineering plastic made of polyamide = nylon was used.

It is desirable to use an ion generator 5 with a Peltier element. In the Peltier element, condensation is generated on the surface of the Peltier element on the heat absorbing surface side due to a temperature difference from the surroundings, and moisture can be effectively generated. By applying a negative potential between the opposing electrodes using the moisture, charged fine particles charged into negative ions can be produced. By blowing charged fine particles (negative ions combined with water molecules) charged to the negative ions to the hair, generation of static electricity can be prevented and the hair can be given a moist feeling.

In addition, since polyamide = nylon is easy to be positively charged, negative ions (charged fine particles) generated by the ion generator 5 can reduce the charging of the fan and reduce the adhesion of dust to the fan. In addition, when charged fine particles are used as in this embodiment, the generation of static electricity due to moisture can be suppressed.

FIG. 6 is a side perspective view showing an internal configuration of a hair dryer according to Example 4 of the present invention, and FIGS. 7A and 7B are perspective views showing an example of a fan.

The difference between the first to third embodiments and the present embodiment is that the air flow path 7 is not divided vertically and one air flow path is formed. The heater 11 is provided only in the lower part of the air flow path as in the previous embodiments. As shown in FIG. 7A on the blow-out side and FIG. 7B on the suction side, the fan 6 has a blade 6a with a rectifying plate on the blow-out side.

Even in such a configuration, most of the ions generated by the ion generator 5 ride on the parallel wind, pass through the upper side of the air flow path 7, and the wind containing the ions is blown from the discharge port 12 without being heated by the heater 11. Is done. Therefore, it is possible to alleviate problems caused by heating of ions and water molecules bonded to the ions. Further, when positive ions and negative ions are generated, neutralization of both can be prevented.

In addition, when the fan 6 of the fourth embodiment and the partition plate 10 described in the first and second embodiments are used in combination,
Since it is possible to realize that the heat of the heater 11 can be cut off in the air flow path 7 and that the positive ions and the negative ions are prevented from being mixed and neutralized in the air flow path 7, it is more effective. .

FIG. 8 is a side perspective view showing the internal configuration of the hair dryer according to the fifth embodiment of the present invention.

In the present embodiment, unlike the first embodiment, the heater 11 is disposed in the upper air flow path 8, and the air blown from the fan 6 passes through the lower air flow path 9 as it is without the heater 11. Accordingly, the ion generator 5 is also arranged on the lower side. This arrangement is convenient because it is possible to arrange electric circuits such as a power supply circuit of the ion generator 5 around the handle.

In addition, since the user applies hot air to the hair, if the hot air passes through the lower air flow path 9 as in the first embodiment, the ion wind that has passed through the upper air flow path 8 may hit other places than the hair. It was. However, if the air flow path through which the hot air passes is the upper upper air flow path 8, it is preferable because the time during which the ion wind that has passed through the lower air flow path 9 hits the hair increases.

9A and 9B are perspective views of a hair dryer according to Example 6 of the present invention.

In the sixth embodiment, a specific configuration for removing the intake filter 3 from the housing 2 for maintenance of the ion generator 5 is shown.

First, as shown in FIG. 9A, the intake filter 3 is removed from the housing 2. The intake filter 3 and the housing 2 may be attached by claws, may be attached using magnets, or may be rotated and removed, and the specific configuration is not particularly limited. .

Next, the ion generator 5 is removed from the housing 2 as shown in FIG. 9B. In this embodiment, the ion generator 5 can be easily removed from the housing 2 by sliding. The power source of the ion generator 5 can be connected to the power source simply by attaching a connector under the electrode side and inserting and removing it. In addition to the slide mechanism, various forms such as screwing and a push mechanism using a spring can be used.

By removing the intake filter 3 from the housing 2, the ion generator 5 can be easily maintained and replaced. When the needle electrode 15 and the induction electrode 16 of the ion generator 5, particularly the needle electrode 15, generate ions, foreign matter gradually adheres to the surface and does not exhibit performance. In particular, when hair spray is used, the components remain in the air, and when the fan takes in the air, foreign substances are likely to adhere to the surface of the electrode, and the inventors of the present application will not perform at a relatively early stage. Confirmed by experiment. Therefore, it is desirable to periodically perform electrode maintenance or replace the ion generator 5.

As described above, the ion generator 5 can be easily maintained by arranging the ion generator 5 upstream of the fan 6.

FIG. 10 is a side perspective view showing the internal configuration of the hair dryer according to Example 7 of the present invention.

In the seventh embodiment, unlike the previous embodiments, the intake filter 3 is disposed between the ion generator 5 and the fan 6. The ion generator 5 is arranged upstream of the housing 2, that is, upstream of the fan 6 as before.

The air enters through the intake filter 3 and is sucked into the fan 6, and is blown out of the hair dryer 1 from the fan 6 through the air flow path 7 through the discharge port 12 and the nozzle 13. Ions are generated by the ion generator 5 and then blown downstream along the flow of air from the intake filter 3 to the fan 6. Therefore, effects similar to those of the embodiments described so far can be obtained, such as prevention of charging of the fan 6 by ions.

Further, in the present embodiment, when the ion generator 5 is maintained, the maintenance is performed by adopting a structure in which the back cover 17 can be removed, instead of performing the maintenance by removing the intake filter 3 as in the sixth embodiment. . The back cover 17 is preferably made of the same material so as not to impair the sense of unity with the housing 2 in appearance.

As mentioned above, although the Example of this invention was described, various changes besides this can be made. For example, a grid electrode can be used as the ion generator 5, and a sirocco fan as well as a propeller fan can be used as the fan 6. In addition, it cannot be overemphasized that the hair dryer of a new this invention can be guide | induced by combining two or more structures among the structure (invention specific matter) demonstrated in the above-mentioned several embodiment and the above-mentioned several modification. Yes.

The present invention relates to a hair dryer equipped with an ion generator.
