Technical Field

The present invention relates to a heating beauty appliance such as a hair dryer or a hair iron for heating a part of a body such as hair or scalp to beautify the skin.

Background

Hair dryers are generally used to dry hair and scalp, hair straighteners are generally used to straighten hair, and hair curlers are generally used to iron and curl hair. However, with age, secretions from the scalp become less and less moist. Therefore, when the warm air with high temperature from the hair dryer is blown to the scalp, the scalp is excessively dried, which causes itching or the like. In addition, hair is not moisturized and becomes fine with age. As a result, the hair may be discolored or split by heating at high temperature. In order to prevent this, patent documents 1 and 2 disclose a hair dryer provided with a carbon molded body for generating far infrared rays. Thus, even if the heating temperature is lowered, the heating effect is supported by the far infrared rays from the carbon molded body.

Documents of the prior art

Patent document

Patent document 1: japanese registered Utility model No. 3011964

Patent document 2: japanese patent laid-open publication No. 2018-15539

Technical problem to be solved by the invention

However, since the carbon molded body is fragile, it cannot withstand impact, friction, and the like. Therefore, the carbon molded body is brittle-broken by an external force, and thus is cracked. In addition, some of the carbon may be separated into powder or granular form. In such a case, the skin of the user may be contaminated with black color. In patent document 1, in order to cope with such a problem, a carbon molded body is masked with a paint. However, the strength of the coating is insufficient, and therefore the problem of patent document 1 cannot be solved. In addition, the far infrared rays from the carbon molded body are shielded depending on the material of the paint. Therefore, as a result, the heating support effect of the far infrared rays from the carbon molded body is greatly reduced.

Disclosure of Invention

The invention provides a heating beauty appliance which can prevent the damage of a far infrared ray generator such as a carbon forming body and can properly obtain the heating supporting function of the far infrared ray.

Means for solving the problems

In order to achieve the above object, according to a first aspect of the present invention, a heating cosmetic device is provided with a heat source for heating a human body, a far infrared ray generator is provided in the heat source, the far infrared ray generator is housed in a case, and a far infrared ray passage portion is provided in the case.

In the above structure, when the heat source generates heat, the human body is warmed by the heat, and the temperature contributes to beauty. At this time, far infrared rays are generated from the far infrared ray generator by the heat of the heat source. Then, the far infrared rays reach the human body through the passing part of the far infrared rays. Thus, warming is supported by far infrared rays. Further, since the far infrared rays are directly radiated to the human body without using air as a medium, the heating can be performed without heating the medium air or generating loss by diffusing heat through the medium air, and the heating efficiency can be improved. Furthermore, the far infrared ray generator is accommodated in the housing, so that damage is avoided.

Detailed Description

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

(first embodiment)

A first embodiment embodying the present invention as a hair dryer (hereinafter, simply referred to as a hair dryer) 10 will be described with reference to fig. 1 to 5.

As shown in fig. 1 and 2, a motor chamber 13 is disposed at a base end portion of a housing 12 having a handle 11 of a blower 10. A motor (not shown) and a sirocco fan (not shown) rotated by the motor are disposed in the motor chamber 13. An adjustment switch 15 is provided at the handle 11, and the adjustment switch 15 is used to start/stop the motor and the heat generating body 18 and adjust the heat generating temperature of the heat generating body 18. A switch 14 is provided near the adjustment switch 15, and the switch 14 is used to switch the blower 10 between a warm air supply state and a cool air supply state.

A blower tube 16 extending forward from the motor chamber 13 is formed in the housing 12. As shown in fig. 2 and 3, a support member 17 is fixed inside the blower tube 16. The support member 17 has a cross-sectional shape, and has incombustibility, heat resistance and electrical insulation of mica or the like. On the outer periphery of the support member 17, a heating element 18 made of a nichrome wire is spirally wound so as to wrap the support member 17. The motor is driven to suck outside air into the motor chamber 13 through an air inlet 19 in the side surface of the motor chamber 13. The air is then sent into the barrel 16. The air is warmed in the blower tube 16 by the heater 18. Then, the air is discharged to the outside from the front end opening of the blower tube 16.

A support column 21 is attached to the center of the distal end of the support member 17 and to the axial center of the winding region of the heating element 18. The front end of the support column 21 supports a temperature sensor 22 as a human detection sensor. The temperature sensor 22 is disposed facing forward, and detects the temperature of the scalp and hair of the user positioned in front of the temperature sensor 22 when the hair dryer 10 is used. The heat generation temperature of the heat generating body 18 is automatically adjusted based on the detection result of the temperature sensor 22. Therefore, even if warm air is continuously supplied to one part of the scalp, hair, or the like, overheating of the part can be prevented. In addition, if high temperature and low temperature are alternately supplied along with the temperature detection, the stratum corneum shrinks and the polishing action of the stratum corneum can be ensured. In addition, proper blood circulation of the scalp is also promoted.

A far infrared ray generation unit 23 is provided on the rear side of the temperature sensor 22. As shown in fig. 2 to 5, the far infrared ray generation unit 23 includes a rectangular tubular housing 26 having both front and rear ends open, and a molded body unit 24 housed in the housing 26. Fig. 2 shows the far infrared ray generation unit 23 not by a section of the temperature sensor 22 but by a section. The housing 26 is made of a phenol resin containing a carbon component, and has a rectangular tubular shape open in the front-rear direction. The opening on the front side of the housing 26 constitutes a passage portion for far infrared rays.

The molded body unit 24 is composed of a carbon molded body (hereinafter, simply referred to as a molded body) 25 in a rectangular parallelepiped shape and a cover sheet 27 covering the periphery of the molded body 25. The formed body 25 is made of high-purity graphite. The cover sheet 27 is made of polytetrafluoroethylene (hereinafter referred to simply as teflon (trade name)) which is a compound of fluorine and carbon. The cover sheet 27 is wound around the outer periphery of the molded body 25 so as to cover both the upper and lower surfaces and both the front and rear surfaces of the molded body 25. Therefore, the side surfaces of the molded body 25 of the front and rear openings of the housing 26 are closed by the cover sheet 27. Further, a cover sheet 27 is interposed between the outer peripheral surface of the molded body 25 and the inner peripheral surface of the housing 26.

The blower 10 of the present embodiment functions as follows.

When the hair dryer 10 is used, the heating element 18 generates heat and warm air heated by the heating element 18 is discharged forward from the distal end opening of the air blowing tube 16. Therefore, the hair can be dried, styled, and the like by the warm air. At this time, the molded body 25 is surrounded on its periphery by the heating element 18 and heated by the heating element 18. Thus, far infrared rays are generated from the formed body 25. The far infrared rays are supplied from the front side of the housing 26 to the outside through the cover sheet 27. Further, the cover sheet 27 contains a carbon component. Therefore, the cover sheet 27 is heated by the heat of the heating element 18 and the far infrared rays from the molded body 25, and generates far infrared rays.

Thus, far infrared rays are supplied from the opening of the housing 26 toward the user. Further, since the case 26 is made of a phenol resin containing a carbon component, the case 26 also generates far infrared rays by heat from the heating element 18. Therefore, the far infrared ray and the heat of the warm air can be used together for drying, setting, etc. of the hair.

Therefore, the blower 10 of the first embodiment has the following effects.

(1) In the hair dryer 10, when the heating element 18 heats the hair, the far infrared rays generated from the molded body 25 contribute to hair drying, hairstyle setting, and the like. Therefore, the amount of heat generated by the heating element 18 can be reduced, and thus power consumption can be reduced, and damage to the scalp and hair can be reduced. That is, in a state where far infrared rays, which is one kind of electromagnetic waves, are supplied to the hair and scalp, moisture in the hair and scalp is heated by microwave vibration resonance. Therefore, even if the heating element 18 is not heated to a high temperature to such an extent, drying can be effectively performed and blood circulation can be promoted. In this way, excessive temperature rise of the hair and scalp due to the heating element 18 is prevented during the hair drying, setting, and the like, and low-temperature drying and low-temperature setting can be performed. Therefore, damage due to heat of the hair and scalp can be avoided, and skin and hair care can be promoted. Further, since the far infrared rays contribute to the temperature of the warm air, drying and setting can be efficiently performed in a short time even if the warm air is at a low temperature. Further, even when the hair dryer 10 is used away from the scalp, the far infrared rays easily reach the scalp. Therefore, the scalp can be appropriately warmed, thereby contributing to the promotion of blood circulation.

(2) The molded body 25 is accommodated in a hard case 26 made of a phenol resin. Therefore, the physical external force can be suppressed from acting on the molded body 25 made of graphite, which is a brittle material. Therefore, the molded body 25 can be protected, and brittle fracture of the molded body 25 can be prevented. Therefore, the function of generating far infrared rays is not impaired, and the skin and the like are not contaminated by the broken graphite powder, particles, and the like. Further, the front surface of the molded body 25, i.e., the portion located at the front side open portion of the housing 26 is covered with a cover sheet 27. Therefore, fine particles constituting a part of the carbon of the molded body 25 can be prevented from scattering in the form of soot. This also prevents the graphite powder, granules, and the like from contaminating the skin and the like.

(3) A cover sheet 27 having flexibility compared to the case 26 is interposed between the molded body 25 and the case 26. Therefore, the physical external force to the molded body 25 is buffered by the cover sheet 27. Therefore, the protective function for the molded body 25 can be further improved. The cover sheet 27 covers the molded body 25 at the opening of the case 26. Therefore, the molded body 25 can be protected more reliably. Therefore, even if the blower 10 is dropped to a hard floor, the blower 25 is hardly cracked. Therefore, the molded body 25 can be effectively protected.

(4) The cover sheet 27 is made of teflon containing a carbon component. Therefore, not only the far infrared rays transmit through the cover sheet 27, but also the far infrared rays are generated from the cover sheet 27 by the heat from the heating element 18. The cover sheet 27 also generates heat by the far infrared rays from the molded body 25, and generates far infrared rays. The housing 26 is made of a phenolic resin containing a carbon component. Therefore, far infrared rays are also generated from the case 26 by the heat from the heating element 18. Therefore, the drying, setting, etc. of the hair can be appropriately supported by the far infrared rays.

(5) Since the cover sheet 27 is made of teflon having heat resistance, the durability is excellent.

(6) The molded body unit 24 having the molded body 25 is located at the center of the winding region of the heating body 18. Therefore, the molded body unit 24 does not obstruct the flow of air passing through the heating element 18. Therefore, a smooth flow of warm air can be obtained. Further, the formed body unit 24 can obtain effective radiant heat almost equally from the periphery of the 360 degree range. Therefore, a sufficient amount of far infrared rays can be generated.

(7) The formed body 25 is lighter than the same volume of ceramic having far infrared ray generating action. Therefore, the blower 10 can contribute to weight reduction.

(second embodiment)

Next, a second embodiment embodying the present invention as a hair iron 30 as a hair iron will be described based on the drawings of fig. 6 to 9.

As shown in fig. 6 and 7, in the hair straightener 30, a pair of iron pieces 31 are connected at the proximal end so as to be openable and closable. The one iron tip 31 is provided with a start switch 32 and an adjustment switch 33 for adjusting the heating temperature of a heating element 38 described later.

As shown in fig. 8 and 9, a recess 34 is formed on the tip end facing surfaces of the iron pieces 31. The far infrared ray generation unit 35 is housed and fixed in the recess 34. The far infrared ray generation unit 35 includes a bottom member 36 located on the inner bottom side of the concave portion 34, a plate spring 37 located inside the bottom member 36, a heating element 38 composed of a ceramic heater located on the plate spring 37, and the molded body unit 24 located on the heating element 38. The formed body unit 24 constitutes a part of the far infrared ray generation unit 35. The molded body unit 24 includes a plate-shaped molded body 39 and a case 40 covering the molded body 39 and having a heat sink function. A cover sheet 41 made of teflon is adhered to the upper surface of the housing 40. An elastic block 46 made of silicone rubber is interposed between the inner bottom surface of the concave portion 34 and the far infrared ray generation unit 35.

The molded body 39 is made of high-purity graphite as in the above embodiment. The housing 40 is made of a metal having good heat conduction, such as aluminum or an aluminum alloy. Fixed-side stoppers 42 are formed on both sides of the base member 36. Movable-side stoppers 43 opposed to the inner surfaces of the fixed-side stoppers 42 are formed on both sides of the housing 40. The plate spring 37 presses the heating element 38 without a gap from the molded body 39. Further, the formed body 39 is pressed by the plate spring 37 without a gap from the inner seating surface 45 of the housing 40. Further, the housing 40 is urged to the projecting side by the plate spring 37 until the position is regulated by the fixed-side stopper 42. The case 40 is formed with a plurality of through holes 44 facing the heating element 38. The through holes 44 constitute a passage portion for far infrared rays.

When the hair straightener 30 is used, the housing 40 is heated by the heat of the heating element 38, and the cover sheet 41 is also heated. At this time, far infrared rays are generated from the molded body 39. The far infrared rays pass through the through holes 44 of the outer case 40, pass through the cover sheet 41, and are emitted to the outside. The cover sheet 41 is heated by the far infrared rays from the molded body 39 and the heating element 38, and generates far infrared rays.

Therefore, if the hair straightener 30 is slid so as to comb along the longitudinal direction of the hair in a state where the iron pieces 31 are closed to hold the hair therebetween, the hair can be straightened. In this case, the far infrared ray generation unit 35 is levitated up and down by elastic deformation and repulsive force of the plate spring 37 and the elastic block 46 in order not to apply an unreasonable force to the hair.

In addition to the temperature warmed by the heating body 38, a large amount of far infrared rays are supplied to the hair. Therefore, even if the heating temperature is low, the hair can be effectively heated from the inside of the hair by the far infrared rays as electromagnetic waves and set into straight hair. Therefore, the hair can be prevented from being carbonized, and damage to the hair can be reduced as much as possible.

Therefore, the second embodiment can obtain the following effects.

(1) Since the far infrared rays from the formed body 39 and the cover sheet 41 can be used for setting the hair, the hair can be appropriately set without increasing the heating temperature as described above. Therefore, the hair can be styled in a short time. In addition, the moisture of the hair is less evaporated, and the moisture amount can be maintained in an appropriate amount, so that damage to the hair can be greatly reduced. Therefore, the luster of the hair can be maintained and the split and discoloration can be avoided as much as possible.

(2) The surface of the housing 40 is covered with a cover sheet 41 made of teflon having a small friction coefficient. Therefore, the hair can be smoothly stretched with less resistance. Therefore, as described above, the hair can be prevented from being damaged, the luster of the hair can be maintained, and the split or discoloration can be avoided as much as possible. In addition, since resistance to the permanent wave action is small, setting can be performed smoothly and easily.

(3) The housing 40 is formed with a through hole 44. Therefore, the far infrared rays generated from the molded body 39 easily reach the cover sheet 41 through the through holes 44. In this case, not only the far infrared rays are emitted through the cover sheet 41, but also the far infrared rays from the molded body 39 promote the heat generation of the cover sheet 41, so that a further large amount of far infrared rays are generated and can be used for the hair straightener 30.

(4) The through hole 44 of the housing 40 is closed by the cover sheet 41. Therefore, even when the wet hair is brought into contact with the iron, it is possible to prevent water droplets and moisture from entering the hair straightener 30 through the through hole 44. Therefore, the electric parts inside the hair straightener 30 can be protected.

(5) The molded body 39 is accommodated in the housing 40 via the plate spring 37. Further, the housing 40 is covered with a flexible cover sheet 41. The far infrared ray generation unit 35 having the molded body 39 is received in the soldering iron chip 31 by the elastic block 46 made of silicone rubber. Therefore, even if the iron pieces 31 are roughly processed, for example, the iron pieces 31 are closed by force to cause the two iron pieces 31 to collide with each other, the collision is absorbed at a plurality of locations by the cover sheet 41, the leaf spring 37, and the elastic block 46. Therefore, the molded body 39 can be prevented from being cracked or the like.

(third embodiment)

Next, a third embodiment embodying the present invention as a hair curler 50 as a hair curler will be described based on the drawings of fig. 10 to 12.

As shown in fig. 10 and 11, the hair curler 50 includes a rod-shaped iron body 51 having a cylindrical peripheral surface, and a pressing lever 53 that can be connected to the iron body 51 by a shaft 52 so as to be opened and closed at a proximal end thereof. The soldering iron main body 51 includes a handle portion 54 and a heating portion 55 constituting a far infrared ray generating means. The handle 54 is provided with a start switch 56 and an adjustment switch 57 for adjusting the temperature of a heating element 67 to be described later. The pressing lever 53 has an operating portion 58 and a pressing portion 59 having an arc-shaped cross section along the outer peripheral surface of the heating portion 55 of the soldering iron main body 51.

As shown in fig. 11 and 12, the heating portion 55 is made of a metal having good heat transfer, for example, aluminum or an aluminum alloy. The heating unit 55 includes a pair of semi-cylindrical housings 61 constituting a radiator. The entire outer periphery of the housing 61 is covered with a cylindrical cover sheet 60 made of teflon. The two shells 61 are closed between their two side edges by a rod-shaped seal 62. A plurality of through holes 63 constituting a passage portion for far infrared rays are provided in the center portions of the two housings 61 in the width direction. Seating surfaces 64 are formed inside the through holes 63 of the two housings 61.

A pair of receiving portions 65 are formed inside the two housings 61. Between the two receiving portions 65, a receiving plate 66 is supported via a leaf spring 69. A plate-shaped heating element 67 formed of a ceramic heater is supported by the support plate 66. A plate-like formed body 68 made of graphite is supported on the heating element 67. The heating element 67 is pressed without a gap from the forming body 68 by the spring force of the plate spring 69, and the forming body 68 is pressed without a gap from the seating surface 64. Thereby, the formed body 68 is seated on the seating surface 64. The housing 61 constitutes a housing of the shaped body 68.

When the curling iron 50 of the third embodiment is used to perform the hair curling, the heating elements 67 disposed at two locations separated by 180 degrees generate heat, and the entire molded body 68, the housing 61, and the cover sheet 60, that is, the entire heating unit 55 is heated. Then, the hair is wound around the heating portion 55 of the iron body 51, and the hair is pressed and held between the pressing rod 53 and the heating portion 55. Thus, the hair is warmed and set in a curled state. At this time, far infrared rays are generated from the formed body 68. Then, the far infrared rays reach the cover sheet 60 through the through holes 63, pass through the cover sheet 60, and are emitted to the outside. The cover sheet 60 also generates heat by the far infrared rays, and the cover sheet 60 is also heated by the heat of the heating element 67. Thereby, far infrared rays are also emitted from the cover sheet 60. Therefore, when curling hair and setting hair, the heating element 67 can be used for direct heating and the far infrared ray can be used for auxiliary heating. Therefore, in the third embodiment, the same action and effect as those of the second embodiment can be obtained.

The present invention is not limited to the configurations of the above embodiments, and can be embodied in the following forms.

In the first embodiment, as the case 26, a material that generates far infrared rays, such as teflon, PPS (polyphenylene sulfide resin), or carbon reinforced resin, may be used in addition to the phenol resin.

In the first embodiment, the support 21 and the temperature sensor 22 at the front end opening of the blower tube 16 may be omitted, and the far infrared ray generation unit 23 having the molded body 25 may be provided at the relevant portion.

In the first embodiment, the shaped body 25 has a rectangular parallelepiped shape, but the shape of the shaped body 25 may be changed to a cubic shape, a spherical shape, a cylindrical shape, a prismatic shape, a polyhedral shape other than a hexahedron, or the like. In this case, it is preferable to change the shape of the housing 26 in accordance with the shape of the molded body 25.

In the first embodiment, the housing 26 is configured in a rectangular tubular shape and the front and rear of the housing 26 are opened, but the front side of the housing 26 may be opened or the rear side may be closed.

In the third embodiment, the formed body 68 may be provided only on the housing 61 near the press rod 53.

In the third embodiment, the cross-sectional shape of the molded body 68 may be formed in an arc shape along the inner peripheral surface of the housing 61.

In the first to third embodiments, instead of the cover sheets 27, 41, 60 made of teflon, a material that easily transmits far infrared rays, for example, high density polyethylene, may be used.

The present invention may be embodied as a heating cosmetic device other than the hair dryer 10, the hair straightener 30, and the hair curler 50 of the above embodiments, for example, a hair dryer having a comb and discharging air from the root of the comb.

As the molded bodies 25, 39, 68, ceramics such as alumina resin, diatomaceous earth, for example, may be used in addition to graphite.
