(Summary of the hair dryer) Fig. 1 is a side view of the hair dryer of this embodiment, and Fig. 2 is a perspective view of the hair dryer shown in Fig. 1.

As shown in Fig. 1, the hair dryer has a structure in which a handle 2 is attached to a cylindrical casing 1. One end of the casing 1 is a suction port 11, the other end is an exhaust port 12, and the inside of the casing 1 is an air duct. At the suction port 11, a net plate-shaped suction port cover is installed. The air passing through the suction port cover is sucked into the housing 1 from the suction port 11. In addition, the suction port 11 may also be provided on the side surface of the housing 1. The handle 2 is provided with an operating part 21 for the user to operate the hair dryer. In addition, a power cord (not shown) is connected to the handle 2. The hair dryer is supplied with electric power from the outside via the power cord. In addition, the hair dryer is provided with a cover 3 covering at least a part of the user's head in order to regulate the user's scalp environment. The hair dryer includes at least a cover 3 and a control unit 17 that performs light emission control of the LED light emitting unit 34 described later.

(Internal structure of the hair dryer) Figure 3 is a side sectional view showing the internal structure of the hair dryer shown in Figure 1.

Inside the casing 1, as shown in FIG. 3, a blower 14 for blowing air along the tube length direction of the casing 1 is arranged. An example in which the blower 14 is an axial fan is shown in FIG. 3. By the action of the blower 14, the outside air is sucked in from the suction port 11, the inside of the casing 1 is used as an air path to generate air flow, and the air flow is released from the exhaust port 12. Between the blower 14 and the exhaust port 12, a heater 15 for heating air is arranged. For example, the heater 15 has a structure in which an electric heating wire is wound around a support plate arranged in the casing 1. The heater 15 heats the air in the housing 1 so that the air flow released from the exhaust port 12 is warm air.

The hair dryer is provided with an ion generating unit (charged particle generating unit) 16 that generates air ions (charged particles) in the air. The ion generating unit 16 is arranged in the casing 1. The ion generating unit 16 includes a needle-shaped discharge electrode, and an annular induction electrode surrounding the discharge electrode. A voltage is applied between the discharge electrode and the sensing electrode to generate a corona discharge. The corona discharge generates air ions around the discharge electrode. Ion generating means 16 in order that the H ⁺ (H ₂ O) _m and other positive air ions and _{^{O 2 - (H 2 O)}} n both negative air ions and the like to produce, having two sets of electrode groups and the discharge of the sensing electrode. The ion generating unit 16 generates positive and negative air ions in the air in the casing 1. The air ions generated by the ion generating unit 16 are mixed into the air in the casing 1, and the air flow containing the air ions is released from the exhaust port 12.

The hair dryer is equipped with a control unit 17 that controls the operation of each part. The control unit 17 is connected to the operation unit 21, the blower 14, the heater 15, and the ion generation unit 16. The control unit 17 controls the operations of the blower 14, the heater 15 and the ion generation unit 16 according to the operation from the user received by the operation unit 21.

Furthermore, the control unit 17 performs light emission control of the LED light emitting unit 34 provided in the cover 3. In addition, the control unit 17 may prohibit the operation of the blower 14 and the ion generation unit 16 during the period when the operation of the heater 15 is prohibited.

(Structure of the cover) FIG. 4 is a side cross-sectional view showing the internal structure of the cover 3, and FIG. 5 is a side cross-sectional view of the periphery of the LED light-emitting part 34 provided in the cover 3.

As shown in FIG. 4, the cover 3 has a substantially cylindrical shape with an opening 31, and an air passage is formed in the opening 31, and a head stimulating body 33 for stimulating the user's head is provided in the air passage. The head stimulating body 33 is shaped like a finger. The head stimulating body 33 has a plurality of rod-shaped bodies 331 that simulate fingers. The plurality of rod-shaped bodies 331 are arranged with their front ends passing through the opening 31 toward the outside of the cover 3. The head stimulation body 33 contacts the head H of the user. That is, each rod-shaped body 331 of the head stimulating body 33 pulls the hair of the head H away and the tip contacts the scalp to stimulate the scalp. In this way, the head stimulation body 33 can stimulate the user's head.

Furthermore, as shown in FIG. 4, a plurality of LED light emitting parts 34 for irradiating the scalp of the head with LED light are provided on the facing surface 31a facing the head H on the side of the opening 31 of the cover 3. For example, as shown in FIG. 2, the LED light-emitting parts 34 are provided on the facing surface 31 a of the cover 3 at a position where the rod-shaped body 331 of the head stimulation body 33 does not block the LED light. In FIG. 2, an example in which 8 LED light-emitting parts 34 are provided is shown, but the number of LED light-emitting parts 34 is not particularly limited.

As shown in FIG. 5, the LED light-emitting portion 34 includes an LED 34 a provided inside the opening 31 b provided on the facing surface 31 a of the opening 31 of the cover 3. As the LED34a, a red LED emitting red LED light is used. The red LED is, for example, an LED that generates red light with a peak wavelength of 630 nm to 660 nm. The red LED light emitted by the LED 34a passes through the opening 31b and irradiates the scalp of the head H contacted by the rod 331 of the head stimulation body 33.

The facing surface 31a of the cover 3 is formed by a highly reflective member. For example, the opposing surface 31a is formed of highly reflective PC (polycarbonate), or aluminum is vapor-deposited to achieve a highly reflective function. In addition, as a method for realizing the high reflection function of the opposing surface 31a, it is not limited to forming with high reflection PC or performing aluminum vapor deposition, and other methods may be used.

(Example of use) Fig. 6 is a schematic diagram showing an example of the use of the hair dryer of the first embodiment. The user holds the hair dryer in such a way that the opening 31 is opposed to the user's head and a part of the head is covered by the cover 3. At this time, the opening 31 is in contact with or close to the head H of the user. In this state, the head stimulating body 33 provided in the opening 31 of the cover 3 contacts the head H of the user. In particular, each rod-shaped body 331 of the head stimulating body 33 pulls the hair apart and the front end contacts the scalp to stimulate the scalp. In this way, the head stimulation body 33 can stimulate the head H of the user.

In addition, when the user's head H is pressed by the cover 3, the unheated air containing charged particles is released from the exhaust port 12, passes through the air passage in the cover 3, and contacts the user's head H .

Furthermore, while the cover 3 is pressing the user's head H, the red LED light is irradiated from the LED34a of the LED light emitting part 34 to the scalp of the user's head H.

Therefore, when the head H of the user is pressed by the cover 3 and red LED light is emitted, the unheated air containing air ions is released from the exhaust port 12, passes through the air passage in the cover 3, and comes into contact with the user The head of the person H. The released air does not dissipate immediately, but stays inside the cover 3 covering a part of the user's head for a certain amount of time. Therefore, the air ions contained in the air do not dissipate and stay in the inside of the cover 3, and concentrate on the part of the user's head covered by the cover 3. By the concentrated action of air ions, the hair and scalp contained in the part covered by the cover 3 will have a higher density of air ions than before. As air ions stay inside the cover 3, the air ions act on the hair and scalp for a longer time than before.

In addition, since the air containing air ions is in contact with the head in the state where the plurality of rods 331 of the head stimulating body 33 pull the hair apart, the air ions effectively contact the hair and scalp, and the air ions effectively act Apply to hair and scalp. Therefore, the hair and scalp can be neutralized, sterilized and moisturized, and the environment of the hair and scalp can be adjusted. In addition, the user's scalp is stimulated by the head stimulating body 33 while being stimulated by air ions, so the environment of the scalp is expected to be adjusted.

Furthermore, in a state where the plurality of rod-shaped bodies 331 of the head stimulating body 33 pull the hair apart, the red LED light emitted by the LED34a of the LED light-emitting part 34 irradiates the scalp, so it is expected that the environment of hair and scalp conditioning can be expected.

As described above, when the LED34a of the LED light-emitting portion 34 of the cover 3 emits light, the heater 15 does not heat the air, so the heated air is not released from the exhaust port 12. In the case of heating air, the heated air continues to concentrate on a part of the user's head, which makes it difficult to dissipate heat from the air-contacting surface. In the present embodiment, since the air is not heated when the LED34a of the LED light-emitting portion 34 of the cover 3 emits light, the air that touches the user's head is unheated air, so it is easy to make contact with the air-contacting surface Heat dissipation.

Here, because the brighter the red LED light of the LED34a of the LED light-emitting portion 34, the better the scalp environment. Therefore, as described above, the facing surface 31a of the opening 31 of the cover 3 is formed of a highly reflective member. As a result, the light directly irradiated from the LED34a and the light reflected by the light irradiated from the LED34a on the highly reflective member of the opposing surface 31a are irradiated to the scalp of the head H, so the scalp of the head H is irradiated with a high-illuminance red LED Light.

Furthermore, in order to adjust the scalp environment, it is desired to irradiate the red LED light to the scalp in a wide range or to irradiate a certain point of the scalp with high irradiation intensity. To achieve this, it is considered that a convex lens or a concave lens is installed in the opening 31b formed in the opening 31 of the cover 3.

(Lens) For example, as shown in Fig. 7(a), since each opening 31b formed on the facing surface 31a of the cover 3 is embedded with a convex lens 35, it is possible to illuminate a certain point of the scalp with high-intensity red LED light .

In addition, as shown in FIG. 7(b), the concave lens 36 is inserted into each opening 31b formed in the facing surface 31a of the cover 3, so that the scalp can be irradiated in a wide range.

In addition, the lens (convex lens 35, concave lens 36) may be provided in each LED light-emitting part 34, only the convex lens 35 or only the concave lens 36 may be embedded in the opening 31b, or the convex lens 35 and the concave lens 36 may be mixed and embedded in the opening 31b.

In this way, by providing the lens (convex lens 35, concave lens 36) in each LED light emitting part 34, the red LED light can be diffused or converged in each LED light emitting part 34. Thereby, the irradiation range of the red LED light can be appropriately set according to the user's scalp environment. That is, it is possible to irradiate a part of the scalp with LED light in a wide area, and irradiate a part of the scalp with LED light in a small area (a certain point). For example, when you want to irradiate a part of the scalp of the head H with red LED light, embed the convex lens 35 in the opening 31b of the corresponding part, and when you want to irradiate the other part with red LED light in a wide range, the opening at the corresponding part The concave lens 36 may be embedded in 31b. In this way, it is only necessary to set the number of convex lenses 35 and concave lenses 36 and the insertion positions according to the purpose.

As shown in FIG. 7(a) and (b), if the convex lens 35 and the concave lens 36 are respectively fitted into each opening 31b, it is difficult to attach and detach the lens. Therefore, in the situation shown in Fig. 7(a)(b), the cover 3 must be prepared separately according to the user's purpose of use. That is, it needs to be divided into a cover 3 with a convex lens 35 and a cover 3 with a concave lens 36.

In this regard, for example, as shown in FIG. 8(a), it is considered to use a first support plate (lens support plate) 351 made of a transparent resin in which a convex lens 351a is integrally formed. The convex lens 351a is formed so that when the first support plate 351 is in contact with the facing surface 31a, it reaches a position corresponding to the opening 31b.

Furthermore, for example, as shown in FIG. 8(b), it is considered to use a second support plate (lens support plate) 361 containing a transparent resin in which a concave lens 361a is integrally formed. The concave lens 361a is formed so that when the second support plate 361 is in contact with the facing surface 31a, it reaches a position corresponding to the opening 31b.

The first support plate 351 and the second support plate 361 are freely attachable and detachable with respect to the facing surface 31a. Thereby, there is no need to prepare the cover body 3 separately according to the user's purpose of use. By installing either the first support plate 351 or the second support plate 361 to one cover body 3, the user's purpose of use can be achieved. That is, to irradiate a certain point of the scalp with high-intensity red LED light, attach the first support plate 351 to the cover 3, and to irradiate the scalp in a wide range, attach the second support plate 361 to the cover 3 is fine.

In addition, on the lens support plates (the first support plate 351 and the second support plate 361), only the convex lens 351a or only the concave lens 361a may be formed respectively, or the convex lens 351a and the concave lens 361a may be formed by mixing. In this case, as described above, the irradiation range of the red LED light can be appropriately set according to the user's scalp environment. That is, a part of the scalp can be irradiated with LED light in a wide range, and a part of the scalp can be irradiated with LED light in a small range (a certain point). For example, when the red LED light is to be intensively irradiated to a part of the scalp of the head H, the convex lens 351a opposite to the opening 31b of the corresponding part is formed, and when the other part is to be irradiated with red LED light in a wide range, it is formed and corresponding It is sufficient that the opening 31b of the position corresponds to the concave lens 361a. In this way, the number of convex lenses 351a and concave lenses 361a and the positions facing the opening 31b can be formed according to the application.

In addition, in this embodiment, as shown in FIG. 6, the user uses the cover 3 in the state of the housing 1. However, in the following embodiments, an example of using the cover 3 alone is used Description.

Fig. 9 is a side view of the hair dryer with the cover 3 separated from the housing 1. Fig. 10 is a perspective view of the hair dryer with the cover 3 separated from the housing 1.

As shown in FIG. 9, the cover 3 has a structure that can be attached to and detached from the housing 1. One end of the air path of the cover 3 is a connection port 32 connected to the exhaust port 12 when the cover 3 is installed in the casing 1. The other end of the air path of the cover 3 is an opening 31 which is larger than the exhaust port 12. When the cover 3 is installed in the casing 1, the air released from the exhaust port 12 passes through the air passage in the cover 3 and is released from the opening 31.

As shown in FIG. 10, the hair dryer is provided with a push switch 13 that is pressed when the cover 3 is mounted on the housing 1. The push switch 13 is arranged at a position opposite to the cover 3 mounted on the housing 1. The push switch 13 is in a pressed state when the cover 3 is installed on the casing 1, and is in a non-pressed state when the cover 3 is not installed. The push switch 13 is connected to the aforementioned control unit 17. The control unit 17 prohibits the operation of the heater 15 when the push switch 13 is pressed. In addition, the control unit 17 can operate the heater 15 when the push switch 13 is not pressed. In this way, the air blower does not use the heater 15 to heat the air when the cover 3 is mounted on the housing 1.

Furthermore, when the cover 3 is mounted on the housing 1 and the push switch 13 is pressed, power is supplied from the inside of the housing 1 to the LED light emitting unit 34 of the cover 3.

(Structure of the cover) FIG. 11 is a side sectional view showing the internal structure of the cover 3.

As shown in FIG. 11, the housing 1 is provided with a power transmitting unit (power supply unit) 50, and the cover 3 is provided with a power receiving unit 51. When the cover 3 is attached to the casing 1, the power receiving unit (power supply unit) 51 receives the power from the power transmitting unit 50 of the casing 1 to drive the LED light emitting unit 34. In addition, when the cover 3 is removed from the housing 1, the power receiving unit 51 receives power from an external power source to drive the LED light emitting unit 34. Here, the power receiving unit 51 is provided with a terminal for connecting an AC (Alternating Current) socket, or a USB (Universal Serial Bus: Universal Serial Bus) (registered trademark) terminal, etc., and is connected to the AC socket or USB (Registered trademark) The cable receives power from the outside.

In addition, the cover 3 may be equipped with a battery, and when it is removed from the housing 1, the LED light emitting unit 34 is driven by electric power from the battery.

(Example of use) FIG. 12 is a schematic diagram showing an example of the use form of the cover 3 of the second embodiment. The user makes the opening 31 of the cover 3 face the user's head, and covers a part of the head with the cover 3, the head H of the user is stimulated by the head stimulation body 33, and the red LED light is emitted from the LED The LED34a of the part 34 irradiates the scalp of the head H of the user.

In this case, as in the first embodiment, since the cover 3 is not used as a part of the hair dryer, air ions cannot be blown to the scalp, but the cover 3 alone is operated without the housing 1, so LED light is used When the part 34 irradiates the scalp with red LED light, it can reduce the burden on the user. That is, in order to adjust the scalp environment, it is necessary to ensure the irradiation time of the red LED light (for example, 20 minutes). Therefore, if the LED light-emitting part 34 can be lighted by the cover 3 alone, the weight of the hair dryer can be reduced, and the user can be reduced burden.

In addition, in the cover 3 alone, since the air heated by the heater 15 in the housing 1 is not released, it is easy to contact the air of the head of the user who uses the cover 3 to adjust the scalp environment. Surface heat dissipation.

[Embodiment 3] Other embodiments of the present invention will be described as follows. In addition, for convenience of description, members having the same functions as those described in the above-mentioned embodiment are given the same reference numerals, and their description is omitted.

(Outline of the hair dryer) Figure 13 is a side view of the hair dryer of this embodiment.

As shown in FIG. 13, the hair dryer is different from the hair dryer of the first embodiment described above in that the connecting member 60 connecting the cover 3 and the housing 1 has flexibility.

(Structure of the cover) FIG. 14 is a side sectional view showing the internal structure of the cover 3.

As the connecting part 60, as shown in FIG. 14, for example, it is preferable to have a bellows shape. In this way, the connecting part 60 that connects the cover 3 and the housing 1 has flexibility, and when the cover 3 is in contact with the head H of the user, the flexibility of the connecting part 60 makes the cover Since the body 3 is tilted relative to the housing 1, it cannot easily contact the head stimulation body 33 according to the shape of the head H. Moreover, even when the head stimulating body 33 of the cover 3 is pressed against the user's head with excessive force, the pressing force will be absorbed by the connecting part 60, and a moderate stimulation is given to the head. Moreover, in addition to applying a moderate stimulus to the head H by the head stimulating body 33, the red LED light of the LED light emitting part 34 also irradiates the scalp, so the scalp environment can be adjusted.

In addition, the tilted state of the cover 3 can also be maintained. In this case, the pipe portion is preferably a corrugated pipe containing metal, or a corrugated pipe containing metal wire in a vinyl chloride pipe.

Moreover, as the connecting part 60, in addition to the bellows, a molded body of silicone resin may be used.
