Description

Heating beauty appliance

The present invention relates to a hair dryer and electric rod coil for heating hair and scalp and other heating beauty appliances.

Hair dryers for drying hair and scalp, ion clips for straightening hair, and curling irons for curling hair are commonly used. However, as we age, the secretions from the scalp decrease and become no longer moisturized. Therefore, if the high-temperature wind of the hair dryer is blown on the scalp, the scalp becomes too dry, which may cause itching. In addition, hair will become slender as it becomes less moisturized with age. As a result, the hair will be discolored or branched due to high temperature heating. In order to prevent this, in Patent Document 1 and Patent Document 2, a hair dryer is provided with a carbon molded body for generating far infrared rays. Thereby, even if the heating temperature is low, the heating effect can be assisted by the far infrared rays from the carbon formed body.

However, since the carbon formed body is fragile, it is not resistant to impact, friction, etc. Therefore, the carbon formed body may be broken due to brittle failure by external force. In addition, part of the carbon may become powdery or granular and separate. In such cases, the user's skin may be blackened. In Patent Document 1, in order to cope with these problems, the carbon molded body is coated with a coating agent. However, since the strength of the coating agent is insufficient, the problem in Patent Document 1 cannot be eliminated. Also, according to the material of the coating agent It may shield the far infrared rays from the carbon formed body. Therefore, the heating assist effect of the far infrared rays from the carbon formed body is greatly reduced.

The purpose of the present invention is to provide a heating beauty appliance which can prevent the damage of the far-infrared rays generating body such as the carbon molded body, and at the same time can appropriately obtain the heating auxiliary effect promoted by the far-infrared rays.

In order to achieve the above objective, according to the first aspect of the present invention, a heating beauty appliance is provided, which is provided with a heat source for heating the human body, and at the same time, the heat source is provided with a far-infrared ray generator, which is characterized by the aforementioned far-infrared ray generator It is accommodated in the shell, and the shell is provided with a far-infrared passing part.

In the above configuration, when the heat source generates heat, its heat will warm the human body, and Its temperature is used for beauty. At this time, the far-infrared rays are generated from the far-infrared rays generator by the heat of the heat source. In addition, the far infrared rays reach the human body through the passing part of the far infrared rays. Therefore, it is assisted by heating with far infrared rays. In addition, since far-infrared rays do not use air as a medium to directly radiate the human body, heating can be performed without generating heating medium air or heat loss through diffusion of the medium air, which can improve heating efficiency. In addition, since the far-infrared ray generator is contained in the housing, damage can be avoided.

Hereinafter, the embodiment of the present invention will be described based on the drawings.

(First implementation type)

The first embodiment of the present invention embodied as a hair dryer 10 will be explained based on FIGS. 1 to 5.

As shown in FIGS. 1 and 2, a motor chamber 13 is arranged at the base end of the housing 12 having the handle 11 of the hair dryer 10. A motor (not shown) and a multi-blade fan (not shown) rotated by the motor are arranged in the motor room 13. The handle 11 is provided with an adjustment switch 15 for starting and stopping the motor and the heating element 18 and adjusting the heating temperature of the heating element 18. A switch 14 for switching the hair dryer 10 between the warm air supply state and the cold air supply state is provided near the adjustment switch 15.

The casing 12 is formed with a blower tube 16 extending forward from the motor chamber 13. As shown in FIG. 2 and FIG. 3, a support member 17 is fixed inside the blower tube 16. The support member 17 is formed into a cross-section and has the incombustibility, heat resistance, and electrical insulation properties of mica and the like. On the outer periphery of the support member 17, a heating element 18 composed of a nickel-chromium alloy wire is spirally wound to wrap the support member 17. By the driving of the motor, external air is sucked into the motor chamber 13 from the suction port 19 on the side of the motor chamber 13. Then, the air is sent into the blower 16. The air is heated in the blower 16 by the heating element 18. Then, the air is sent to the outside from the front end opening of the blower 16.

A support 21 is attached to the center of the front end of the support member 17 at the axis of the winding area of the heating element 18. The front end of the pillar 21 supports a temperature sensor 22 of a human sensor. The temperature sensor 22 is arranged facing the front, and when the hair dryer 10 is used, it detects the temperature of the scalp and hair of the user located in front of the temperature sensor 22. The heating temperature of the heating element 18 is automatically adjusted based on the detection result of the temperature sensor 22. Therefore, even if the warm air is continuously supplied It can still prevent overheating of the scalp and hair. In addition, if high temperature and low temperature are alternately supplied based on temperature detection, the epidermis is tightened and the moisturizing effect of the epidermis can be ensured. In addition, it also promotes proper blood circulation to the scalp.

A far-infrared generating unit 23 is provided on the rear side of the temperature sensor 22. As shown in FIGS. 2 to 5, the far-infrared generating unit 23 is provided with a quadrangular cylindrical casing 26 with its front and rear ends opened, and a molded body unit 24 housed in the casing 26. FIG. 2 does not show the part of the temperature sensor 22 in cross section, but shows the far infrared generating unit 23 in cross section. The housing 26 is made of phenolic resin containing carbon components, and is formed into a quadrangular cylindrical shape before and after opening. The front side opening of the housing 26 constitutes a far-infrared passing part.

The molded body unit 24 is composed of a rectangular parallelepiped shaped carbon molded body (hereinafter referred to as a molded body) 25 and a covering sheet 27 covering the periphery of the molded body 25. The molded body 25 is made of high-purity graphite. The cover sheet 27 is made of polytetrafluoroethylene (hereinafter referred to as a brand name Teflon) which is a compound of fluorine and carbon. The covering sheet 27 is wound around the outer circumference of the molded body 25 to cover the upper and lower surfaces and the front and rear surfaces of the molded body 25. According to this, the side surface of the molded body 25 located at the front and rear openings of the housing 26 is blocked by the cover sheet 27. In addition, 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 hair dryer 10 of this embodiment has the following functions.

When the hair dryer 10 is used, while the heating element 18 generates heat, the warm air heated by the heating element 18 is discharged from the front end opening of the blower 16 to the front. Therefore, you can use this warm air to dry or comb your hair. At this time, the periphery of the molded body 25 is surrounded by the heating element 18 and heated by the heating element 18. Therefore, far infrared rays are generated from the molded body 25. The far-infrared rays are transmitted to the cover sheet 27 and supplied to the outside from the front side opening of the housing 26. In addition, the cover sheet 27 contains carbon Minute. 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 to generate far infrared rays.

In this way, far infrared rays are supplied to the user from the opening of the housing 26. Furthermore, since the casing 26 is made of phenol resin containing carbon components, the casing 26 also generates far infrared rays by the heat from the heating element 18. Therefore, far-infrared rays can be used together with the heat of warm air to dry and comb hair.

Accordingly, the hair dryer 10 of the first embodiment has the following effects.

(1) In the hair dryer 10, when the heating element 18 is used for heating, the far infrared rays generated from the molded body 25 can assist the drying of the hair, the combing of the hairstyle, and the like. Therefore, the calorific value of the heating element 18 can be reduced, power consumption can be saved, and damage to the scalp and hair can be reduced. That is, in a state where the hair and scalp are supplied with far infrared rays, which is a kind of electromagnetic waves, the moisture inside the hair and the scalp is heated by micro-vibration resonance. Therefore, even if the heating element 18 does not generate heat at such a high temperature, it can effectively perform drying and promote blood circulation. In this way, excessive heating of the hair and scalp caused by the heating element 18 is prevented during hair drying and combing, so that low-temperature drying and low-temperature combing can be performed. Therefore, heat damage to hair and scalp can be avoided, and skin and hair care can be promoted. In addition, since the far-infrared rays assist the temperature of the warm air, even if the warm air is at a low temperature, drying and combing can be efficiently performed in a short time. Further, even when the hair dryer 10 is used away from the scalp, far infrared rays can easily reach the scalp. Therefore, it can moderately heat the scalp and is useful for promoting blood circulation.

(2) The molded body 25 is housed in a hard case 26 made of phenol resin. Therefore, it is possible to suppress the physical external force from acting on the molded body 25 made of graphite, which is a brittle material. Therefore, the molded body 25 can be protected, and the brittle failure of the molded body 25 can be prevented. According to this, far The infrared generation function will not be damaged, and the skin will not be contaminated by damaged graphite powder or particles. In addition, the front surface of the molded body 25, that is, the portion located at the front open portion of the housing 26 is covered by the cover sheet 27. Therefore, it is possible to prevent the fine particles constituting part of the carbon of the molded body 25 from becoming coal-like and flying away. This can also prevent skin stains caused by graphite powder or granules.

(3) Between the molded body 25 and the housing 26, a cover sheet 27 that is more flexible than the housing 26 is interposed. Therefore, the physical external force on the molded body 25 can be buffered by the cover sheet 27. According to this, the protection function of the molded body 25 can be further improved. In addition, the cover sheet 27 is attached to the opening of the housing 26 to cover the molded body 25. Therefore, the molded body 25 can be protected more reliably. Therefore, even if the blower 10 is dropped on a hard ground, the molded body 25 is difficult to break. Therefore, the molded body 25 can be effectively protected.

(4) The cover sheet 27 is made of Teflon containing carbon. Therefore, not only the far-infrared rays can be transmitted through the cover sheet 27, but also the far-infrared rays are generated from the cover sheet 27 by the heat from the heating body 18. In addition, the cover sheet 27 also generates far infrared rays by the far infrared rays from the molded body 25. In addition, the housing 26 is made of phenol resin containing carbon components. Therefore, by the heat from the heating element 18, the housing 26 also generates far infrared rays. According to this, far infrared rays can be used to appropriately assist the drying and combing of hair.

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

(6) The formed body unit 24 having the formed body 25 is located in the center of the winding area of the heating body 18. Therefore, the molded body unit 24 does not become an obstacle to the air flow passing over the heating element 18. Therefore, a smooth warm air flow can be obtained. Moreover, the shaped body unit 24 can be viewed from 360 degrees Effective radiant heat is almost evenly obtained near the range. Therefore, a sufficient amount of far infrared rays can be generated.

(7) The molded body 25 is lighter than the ceramic with the same volume as the far-infrared ray generating effect, and therefore, can contribute to the weight reduction of the hair dryer 10.

(Second Implementation Type)

Next, the second embodiment of the present invention will be embodied as the ion clamp 30 as an electric rod coil based on the schematic description of FIGS. 6-9.

As shown in FIGS. 6 and 7, in the ion clamp 30, a pair of iron pieces 31 are connected at the base end so that they can be opened and closed. The iron piece 31 on one side is provided with a start switch 32 and an adjustment switch 33 for adjusting the heating temperature of the heating element 38 described later.

As shown in FIGS. 8 and 9, a recessed portion 34 is formed on the facing surfaces of the front ends of the two iron pieces 31. A far-infrared generating unit 35 is accommodated and fixed in the recess 34. The far-infrared generating unit 35 includes a bottom member 36 located on the inner bottom side of the recess 34, a plate spring 37 located inside the bottom member 36, a heating element 38 made of a ceramic heater on the plate spring 37, and a heating element 38 located on the plate spring 37. The shaped body unit 24 on the body 38. The molded body unit 24 constitutes a part of the far-infrared generating unit 35. The molded body unit 24 includes a plate-shaped molded body 39 and a casing 40 covering the molded body 39 and having a heat sink function. A cover sheet 41 made of polytetrafluoroethylene is stuck on the upper surface of the housing 40. An elastic block 46 made of silicone rubber is interposed between the inner bottom surface of the recess 34 and the far-infrared generating unit 35.

The molded body 39 is made of high-purity graphite as in the foregoing embodiment. The housing 40 is made of metal with good thermal conductivity, such as aluminum or aluminum alloy. Fixed-side stoppers 42 are formed on both sides of the bottom member 36. Movable side brakes 43 facing the inner surface of the fixed side brake 42 are formed on both sides of the housing 40. The heating element 38 is pressed by the leaf spring 37 to be free from the molded body 39 gap. In addition, the heating element 39 is pressed by the plate spring 37 until there is no gap between the heating element 39 and the seating surface 45 inside the housing 40. Furthermore, the housing 40 is urged toward the protruding side by the plate spring 37 to a position restricted by the fixed side stopper 42. The housing 40 is formed with a plurality of through holes 44 facing the heating element 38. The through hole 44 constitutes a passage portion of far infrared rays.

When the ion clamp 30 is used, the housing 40 is heated by the heat of the heating element 38, and the covering 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 hole 44 of the housing 40 and pass through the cover sheet 41 to be emitted to the outside. In addition, the cover sheet 41 is also heated by the far infrared rays from the molded body 39 and the heating element 38 to generate far infrared rays.

Therefore, if the ion clip 30 is combed and slid along the length direction of the hair in a state where the iron sheet 31 is closed and the hair is clamped, the hair can be straightened. In this case, in order to prevent excess force from acting on the hair, the far-infrared generating unit 35 uses the elastic deformation and repulsive force of the leaf spring 37 and the elastic block 46 to move up and down in a suspension manner.

In addition to the temperature heated by the heating element 38, the hair is also supplied with a large amount of far infrared rays. Therefore, the heating temperature can not be increased so much, that is, even if the heating temperature is low, the far infrared rays, which are electromagnetic waves, can be effectively heated from the inside of the hair and straightened. Therefore, the carbonization of the hair can be suppressed, and the damage to the hair can be minimized.

Therefore, in the second embodiment, the following effects can be obtained.

(1) Since the far-infrared rays from the molded body 39 and the covering sheet 41 can be used for combing the hair, as described above, the hair can be combed appropriately without increasing the heating temperature. Therefore, the hair can be combed in a short time. In addition, it can reduce the evaporation of moisture in the hair and maintain an appropriate amount of moisture, thereby greatly reducing the damage to the hair. Therefore, the gloss of the hair can be maintained, and branching 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 with a small friction coefficient. Therefore, the hair can be straightened smoothly with a small resistance. Therefore, as mentioned above, the damage of the hair can be suppressed, the gloss of the hair can be maintained, and branching and discoloration can be avoided as much as possible. In addition, since the resistance to the ironing action is small, it can be smoothly and easily groomed.

(3) A through hole 44 is formed in the housing 40. Therefore, the far infrared rays generated from the molded body 39 can easily reach the cover sheet 41 through the through holes 44. In this case, since not only the far infrared rays are transmitted through the cover sheet 41 and emitted, but also the heat generation of the cover sheet 41 is promoted by the far infrared rays from the molded body 39. Therefore, a large amount of far infrared rays are further generated and can be used for the ion clamp 30.

(4) The through hole 44 of the housing 40 is blocked by the cover sheet 41. Therefore, even in the case of ironing wet hair, water droplets and moisture can be prevented from penetrating into the ion clamp 30 from the through holes 44. Therefore, the electrical parts in the ion clamp 30 can be protected.

(5) The molded body 39 is accommodated in the housing 40 by the leaf spring 37. In addition, the casing 40 is covered by a covering sheet 41 having flexibility. Furthermore, the far-infrared generating unit 35 having the molded body 39 is received by the iron sheet 31 by the elastic block 46 made of silicon rubber. Therefore, even if the iron piece 31 is handled roughly, for example, the iron piece 31 is closed violently and the iron pieces 31 collide with each other, the impact will be absorbed by the cover sheet 41, the leaf spring 37, and the elastic block 46 in multiple places. Therefore, cracks and the like of the molded body 39 can be appropriately avoided.

(3rd implementation type)

Next, the third embodiment of the hair curling iron 50 as an electric curling iron will be embodied according to the diagrams in FIGS. 10 to 12.

As shown in Figures 10 and 11, the curling iron 50 is equipped with a rod shape with a cylindrical circumference. The ironing machine main body 51 and the pressing rod 53 facing the ironing machine main body 51 are connected openably and closably at the base end by a shaft 52. The ironing machine main body 51 is equipped with a handle part 54 and a heating part 55 which constitutes a far infrared ray generating unit. The handle 54 is provided with a start switch 56 and an adjustment switch 57 for adjusting the temperature of a heating element 67 described later. The pressing rod 53 has an operating portion 58 and a pressing portion 59 having an arc-shaped cross-section along the outer circumferential surface of the heating portion 55 of the ironing machine body 51.

As shown in FIGS. 11 and 12, the heating part 55 is made of a metal with good heat conduction, such as aluminum or aluminum alloy. The heating unit 55 is provided with a semi-cylindrical casing 61 constituting a pair of heat sinks. The entire outer periphery of the casing 61 is covered with a cylindrical covering sheet 60 made of Teflon. The side edges of the two casings 61 are blocked by a rod-shaped sealing material 62. A plurality of through holes 63 constituting a passage portion of far-infrared rays are provided in the center portions in the width direction of the two housings 61. Seat surfaces 64 are respectively formed on the inner sides of the through holes 63 in the two shells 61.

A pair of support portions 65 are formed on the inside of the two housings 61. The support plate 66 is supported by the leaf spring 69 between the two support portions 65. On the support plate 66, a plate-shaped heating element 67 composed of a ceramic heater is supported. In addition, a plate-shaped molded body 68 made of graphite is supported on the heating element 67. The heating element 67 is pressed by the spring force of the plate spring 69 to have no gap with the molded body 68, and at the same time, the molded body 68 is pressed to have no gap with the seating surface 64. In this way, the molded body 68 is seated on the seating surface 64. The housing 61 constitutes the outer shell of the molded body 68.

When the hair curling iron 50 of the third embodiment is used to curl hair, the two heating elements 67 arranged at 180 degrees apart generate heat to cause the entire molded body 68, the casing 61 and the covering sheet 60, that is, The entire heating unit 55 is heated. Then, it is only necessary to wind the hair around the heating part 55 of the ironer main body 51 while pinching the hair between the pressing rod 53 and the heating part 55. As long as this is done, the hair is heated and combed into curls. At this time, from the formed body 68 produces far infrared rays. In addition, the far infrared rays reach the cover sheet 60 through the through holes 63, and are transmitted to the cover sheet 60 and emitted to the outside. While the cover sheet 60 also generates heat by the far infrared rays, 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 the curls are combed, not only the heating element 67 can be directly heated, but also the far infrared ray assisted heating can be performed.

Therefore, in the third embodiment, the same functions and effects as in the second embodiment can be obtained.

The present invention is not limited to the configuration of the foregoing embodiments, and may be embodied in the following aspects.

In the first embodiment, in addition to phenolic resin, the shell 26 can also be made of Teflon, PPS (polyphenylene sulfide resin), carbon reinforced resin and other materials that generate far infrared rays.

In the first embodiment, although the molded body 25 has a rectangular parallelepiped shape, the shape of the molded body 25 may be changed to a cubic shape, a spherical shape, a cylindrical shape, a corner pillar shape, a polyhedral shape other than a hexahedron, and the like. In this case, it is better to change the shape of the housing 26 in accordance with the shape of the molded body 25.

In the first embodiment, although the housing 26 has a quadrangular cylindrical shape and is configured such that the front and rear sides of the housing 26 are open, it is sufficient that the front side of the housing 26 is open, and the rear side may be closed.

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

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

In the first to third embodiments, materials that easily transmit far infrared rays, such as high-density polyethylene, can also be used instead of the cover sheets 27, 41, 60 made of Teflon.

The present invention can also be embodied as a heating beauty appliance other than the hair dryer 10, ion clip 30, and hair curler 50 of the aforementioned embodiments, for example, a hair dryer that has a comb and releases air from the roots of the comb teeth.

The molded bodies 25, 39, and 68 may be used in addition to graphite, such as ceramics such as alumina resin or diatomaceous earth.
