Description

Technical Field

[0001] This invention relates to a hair dryer.

Background Art

[0002] A hair dryer blows warm air from an outlet onto the hair to set or dry the hair. However, conventional hair dryers simply blow warm air, resulting in a long drying time. In particular, for hair with little moisture content and damaged hair, over-drying may occur, leading to poor cohesion such as spreading. Moreover, the retention of dyes in hair with hair color applied is important for the moisture in the hair. However, excessive drying tends to cause the dyes to be lost and the fading to accelerate.

[0003] Therefore, the applicant has proposed hair dryers (hereinafter referred to as "conventional examples") disclosed in Patent Documents 1 to 7 in order to solve the above-described problems.

[0004] These conventional examples are provided with a far-infrared radiation material at a site where warm air passes. This far-infrared radiation material is heated by the warm air to emit far-infrared rays. Due to the emission of this far-infrared radiation, the hair is warmed from the inside, so the hair can be dried in a short time. Therefore, over-drying of the hair and poor cohesion such as spreading do not occur. Moreover, it is possible to suppress the acceleration of fading of hair with hair color applied.

Mode for Carrying Out the Invention

[0019] Embodiments of the present invention that are considered suitable will be briefly described based on the drawings while showing the operation of the present invention.

[0020] The air from the blower unit 2 passing through the air passage portion 1 is heated by the heating wire 4a disposed on the outer peripheral surface portion of the heating wire support member 4A provided in the air passage portion 1 to become warm air and is blown out from the blowing portion 3.

[0021] By the way, in the present invention, a far-infrared radiation material is provided on the outer peripheral surface portion of the heating wire support member 4A, and the far-infrared radiation material provided on the outer peripheral surface portion of the heating wire support member 4A is heated by the heat generation of the heating wire 4a to generate far-infrared rays. Along with the warm air being blown out from the blowing portion 3, far-infrared rays are radiated.

[0022] Therefore, due to the configuration in which the far-infrared radiation material provided at a position close to the heating wire 4a is heated, far-infrared rays can be efficiently generated.

Example

[0023] Specific embodiments of the present invention will be described based on the drawings.

[0024] This embodiment is a hair dryer in which the blower unit 2 and the blowing portion 3 are connected in series by the air passage portion 1.

[0025] Specifically, in this embodiment, the blower unit 2 and the heater unit 4 are provided in the dryer main body 20.

[0026] The dryer main body 20 is formed of an appropriate synthetic resin member as shown in FIGS. 1 to 3, and includes a cylindrical base portion 20A, an air suction portion 20B connected to the rear end portion of the cylindrical base portion 20A, and a handle portion 20C vertically provided downward from the air suction portion 20B.

[0027] The cylindrical base portion 20A is a hollow structure portion having a circular cross-section with a length in the horizontal direction, and an air passage portion 1 for connecting a blower portion 2 and a blowing portion 3 is provided inside, and a heater portion 4 is provided in the air passage portion 1.

[0028] This heater portion 4 has a heating wire 4a (nichrome wire) that generates heat when energized as shown in FIGS. 2 and 3. This heating wire 4a is spirally wound around a heating wire support member 4A in the longitudinal direction of the heating wire support member 4A. Further, a cylindrical member 4B is fitted onto the heating wire support member 4A around which the heating wire 4a is wound. Note that the heating wire 4a operates and stops by operating an operation portion 22 of the handle portion 20C.

[0029] The heating wire support member 4A is formed of mica having heat insulation properties into a long body with a cross-sectional cross shape. On the other hand, the cylindrical member 4B is formed of planar mica (mica sheet) having heat insulation properties into a cylindrical body with a circular cross-section.

[0030] When the cylindrical member 4B is fitted onto the heating wire support member 4A, a ventilation space is formed between the outer peripheral surface portion of the heating wire support member 4A and the inner peripheral surface portion of the cylindrical member 4B, and the state in which the cylindrical member 4B is fitted onto the heating wire support member 4A is provided in the air passage portion 1 of the dryer main body 20.

[0031] In this embodiment, a far-infrared radiation material and a multi-element mineral material, which will be described later, are provided on the outer peripheral surface portion (the lightly shaded portion in the figure) of the heating wire support member 4A constituting the heater portion 4 and the inner peripheral surface portion (the lightly shaded portion in the figure) of the cylindrical member 4B, respectively.

[0032] Further, a blowing portion 3 is provided at the front end portion of the cylindrical base portion 20A.

[0033] This blowing part 3 is configured by detachably providing a nozzle member formed of an appropriate synthetic resin member as shown in FIGS. 2 and 3 at the front end of the cylindrical base 20A.

[0034] In this embodiment, a far-infrared radiation material and a multi-element mineral material are provided on the inner peripheral surface (the lightly shaded part in the figure) of the blowing part 3 (nozzle member).

[0035] Note that the blowing part 3 may be configured to be integrally provided at the front end of the cylindrical base body 20A.

[0036] Also, at the front end of the cylindrical base 20A and in the air passage part 1 (downstream of the heating wire 4a), a wind rectifying member 5 (diffuser) is provided.

[0037] This wind rectifying member 5 is formed of an appropriate synthetic resin member as shown in FIGS. 2 and 3, and has a configuration in which a lattice member 5” is installed on a circular outer frame member 5’ to have a large number of ventilation small holes 5a, and is detachably fitted and arranged at the front end of the cylindrical base 20A.

[0038] The air from the blowing part 2 passes through the ventilation small holes 5a of this wind rectifying member 5, so that the diffusion of the air flow is suppressed and the wind is rectified.

[0039] In this embodiment, a far-infrared radiation material and a multi-element mineral material are provided on the whole including the ventilation small holes 5a of the wind rectifying member 5 (the lightly shaded part in the figure).

[0040] Note that the wind rectifying member 5 may also be configured to be provided inside the above-described blowing part 3 (nozzle member).

[0041] The air suction part 20B is a hollow structure part that is circular in side view as shown in FIGS. 1 to 3, and air suction ports 21 are provided on each of the left and right flat side surfaces.

[0042] This air intake 21 is configured by providing annular openings on the left and right side surfaces of the air suction part 20B, and a mesh member 21a having a large number of small holes is provided in this air intake 21. Note that the position where this air suction part 20B (air intake 21) is provided is not limited to the position described above, but is provided at an appropriate position according to the structure of the blower part 2 described later.

[0043] Also, a blower part 2 is provided inside the air suction part 20B.

[0044] As shown in FIG. 3, this blower part 2 has a structure in which an electric motor 2a and a rotary vane 2b (sirocco fan) connected to this electric motor 2a are provided.

[0045] Therefore, in the blower part 2, the rotary vane 2b rotates due to the operation of the electric motor 2a, and the air sucked from the air suction part 20B (air intake 21) by the rotation of this rotary vane 2b passes through the cylindrical base part 20A (air passage part 1) and is sent to the heater part 4 and the blowing part 3. Note that the blower part 2 operates and stops by operating the operation part 22 of the handle part 20C, and the structure of the blower part 2 is not limited to the structure described above.

[0046] As described above, the hair dryer according to this embodiment has a far-infrared radiation material and a multi-element mineral material provided in each of the heater part 4 (the electric heating wire support member 4A and the cylindrical member 4B), the air rectifying member 5, and the blowing part 3, and various effects based on far-infrared rays and negative ions can be obtained.

[0047] Specifically, as will be described later, for the heater part 4 (the electric heating wire support member 4A and the cylindrical member 4B), the air rectifying member 5, and the blowing part 3, a coating agent (paint) added with a mixed powder (powder) in which a far-infrared powder and a multi-element mineral powder are mixed is applied to form a coating layer on the surface of each member.

[0048] Examples of far-infrared radiation materials that make up this far-infrared powder include alumina (Al2O3), titania (TiO2), ferrite (Fe2O3), chromium oxide (Cr2O3), silica (SiO2), yttria (Y2O3), magnesia (MgO), etc. Those obtained by pulverizing these into a powder form (powder shape) can be used alone or in combination.

[0049] On the other hand, the multi-element mineral material (multi-element mineral) that makes up the multi-element mineral powder refers to minerals such as perlite, obsidian, and tourmaline (schorl) that have silicon as the main component and contain a number of elements in a well-balanced manner. This multi-element mineral emits negative ions, and when this is applied to the hair as warm air or cold air, the moisture in the hair is mineralized and the protein in the hair is activated.

[0050] The multi-element mineral powder is formed by pulverizing a multi-element mineral with a ball mill or the like into a powder. In this case, the pulverization value is preferably 1 to 3 microns, but the value may vary.

[0051] The multi-element mineral powder can be used alone or in combination, but it is preferably used by appropriately blending two or more types.

[0052] This multi-element mineral powder may be used as it is, or it may be mixed with water, heated or pressurized, and then the supernatant liquid may be made into a powder by vacuum freeze-drying or spray-drying and used.

[0053] In this embodiment, a coating layer (for example, a ceramic coating layer, a plating layer, a fluorine coating layer, a nylon layer, a synthetic resin layer, a silicone rubber layer, a fluorine rubber layer, etc.) is formed by mixing a far-infrared radiation powder or a multi-element mineral powder into a coating agent and applying it to the surfaces of the heater part 4 (the heating wire support member 4A and the cylindrical member 4B), the air-conditioning member 5, and the blowing part 3 respectively. However, the far-infrared radiation powder or the multi-element mineral powder may be kneaded into the heater part 4 (the heating wire support member 4A and the cylindrical member 4B), the air-conditioning member 5, and the blowing part 3 and molded into a predetermined shape.

[0054] Specifically, regarding the method for forming the ceramic coating layer, a coating material prepared by adding far-infrared radiation powder or multi-element mineral powder to heat-resistant formica as a coating agent and making it into a paint form is applied to the heater unit 4 (the heating wire support member 4A and the cylindrical member 4B), the air rectifying member 5, and the blowing unit 3, and then passed through a heating furnace to blow off (bake) the coating agent to form it, and other methods can be used.

[0055] The mixing ratio of the far-infrared radiation powder or multi-element mineral powder to the heat-resistant formica is preferably 3 to 15% by volume ratio, but is not limited to this value.

[0056] And to mix the multi-element mineral powder into the heater unit 4 (the heating wire support member 4A and the cylindrical member 4B), the air rectifying member 5, and the blowing unit 3, for example, the multi-element mineral is pulverized to about 1 to 3 microns by a ball mill, a jet mill, etc. to form a powder, and this is mixed into the raw material of the multi-element mineral (for example, molten metal, molten resin) at a ratio of 0.5 to 10% and molded.

[0057] In this case, it is preferable to appropriately blend and use two or more types of the multi-element mineral powder, but one type may also be used.

[0058] Also, the supernatant liquid obtained after mixing the multi-element mineral powder with water and heating or pressurizing may be mixed, or the powder obtained by vacuum freeze-drying or spray-drying may be mixed.

[0059] The components of perlite, which is an example of the multi-element mineral, are shown in Table 1 below.

[0060]

Table 1

[0061] In addition, in this Table 1, ig·loss conforms to the cosmetic standard of kaolin and the loss on ignition (500 °C, constant temperature).

[0062] Since this embodiment is configured as described above, the air from the blower unit 2 passing through the air passage portion 1 is heated by the heating wire 4a wound around the heating wire support member 4A provided in the air passage portion 1 to become warm air, and is blown out from the blowing portion 3.

[0063] In this embodiment, far-infrared radiation materials (and multi-element mineral materials) are provided on the outer peripheral surface portion of the heating wire support member 4A and the inner peripheral surface portion of the cylindrical member 4B. When the heating wire 4a generates heat, the far-infrared radiation materials (and multi-element mineral materials) provided on the outer peripheral surface portion of the heating wire support member 4A and the inner peripheral surface portion of the cylindrical member 4B are heated, thereby generating far-infrared rays (and negative ions). While the warm air is blown out of the dryer main body 1, far-infrared rays (and negative ions) are radiated.

[0064] In addition to the heater unit 4 (heating wire support member 4A and cylindrical member 4B), far-infrared radiation materials (and multi-element mineral materials) are also provided on the air rectifying member 5 and the blowing portion 3. The warm air passes through these portions and is heated to generate far-infrared rays (and negative ions).

[0065] That is, in this embodiment, since the far-infrared radiation materials (and multi-element mineral materials) provided at a position extremely close to the heating wire 4a are heated, far-infrared rays (and negative ions) can be efficiently generated.

[0066] Therefore, according to this embodiment, since the hair is warmed from the inside by the radiation of far-infrared rays (effective heat conductivity to the hair is obtained), the hair can be dried in a short time. Therefore, there will be no problems such as over-drying of the hair or poor cohesion such as spreading. Moreover, it is possible to suppress the early fading of the hair with hair color applied. That is, since moisture can be given while maintaining the temperature required to dry the hair, moisture can be given to the hair while drying quickly, and the hair can be neatly gathered.

[0067] In addition, in this embodiment, while styling with a hairbrush while caring for the hair with the weak energy radiated from the multi-element mineral material when the hair is dry, together with the far-infrared rays radiated from the far-infrared radiation material, it is possible to promote blood circulation in the scalp to promote hair growth and perform effective scalp care.

[0068] Moreover, even when brushing with a hairbrush due to the action of the multi-element mineral material, static electricity is not generated, and curling, straightening, etc. by brushing can be performed smoothly and styling can also be easily done.

[0069] Furthermore, just by brushing with the negative ions generated from the multi-element mineral material, the blood circulation of the hair and scalp can be improved. Also, the negative ions cause a clustering phenomenon (the force that makes the water molecular group smaller) in the moisture of the hair, enhancing the gloss and moist feeling of the hair and finishing it into a smooth and tidy design.

[0070] In addition, the negative ions act on the cuticle (glass-like fibers) of the hair and can always keep it in a shiny state. In particular, it is effective for damaged hair and fine and difficult-to-tidy hair.

[0071] In addition, in this embodiment, the heating wire support member 4A is formed of a long body having a cross-sectional cross shape, and the heating wire 4a is spirally wound around the outer peripheral surface of the heating wire support member 4A. Therefore, far-infrared rays can be generated well while securing a ventilation space between the surface of the heating wire support member 4A and the heating wire 4a.

[0072] In addition, in this embodiment, a cylindrical member 4B is fitted over the heating wire support member 4A, and a wind rectifying member 5 having a plurality of ventilation small holes 5a is provided at a position downstream of the heating wire 4a. Since a far-infrared radiation material is provided on the inner peripheral surface of the cylindrical member 4B, the ventilation small holes 5a of the wind rectifying member 5, and the inner peripheral surface of the blowing portion 3, in addition to the portions directly heated by the heating wire 4a (the heating wire support member 4A and the cylindrical member 4B), far-infrared radiation materials and multi-element mineral materials are provided at various portions through which the warm air passes, so that the far-infrared effect and the negative ion effect can be obtained to the maximum extent.

[0073] Note that the present invention is not limited to this embodiment, and the specific configurations of the respective constituent elements can be designed as appropriate.
