Summary of the Invention

Problems to be Solved by the Invention

[0004] In the brush attachment shown in Patent Document 1 above, the hair bundles of the brush part are arranged side by side in both the axial direction and the width direction of the tubular body. For this reason, when combing hair along the width direction of the tubular body, the flow of the hair can be straightened. However, since the hair passes linearly through the gaps between the hair bundles, it is difficult to apply an external force to the hair, and it is difficult to correct, for example, bedhead.

[0005] In consideration of the above facts, an object of the present invention is to provide a hair dryer that can easily correct hair habits.

Means for Solving the Problems

[0006] The hair dryer according to claim 1 is a hair dryer including a rod-shaped main body having a grip portion, and a detachable brush portion provided on the tip side of the grip portion in the main body portion, wherein the brush portion includes a base portion to be heated, and an iron portion having first rod-shaped protrusions protruding from the base portion and arranged in a plurality of rows along the longitudinal direction of the main body portion, and an outer peripheral portion provided to protrude on the outer periphery of the iron portion and having second rod-shaped protrusions arranged so as to surround the first rod-shaped protrusions, and the plurality of rows of the first rod-shaped protrusions are arranged with a shift for each row so that no gap is generated when viewed from the width direction of the main body portion.

[0007] In the hair dryer according to claim 1, the base portion of the iron portion is heated and the first rod-shaped protrusions are warmed. Thereby, the hair can be combed while being warmed.

[0008] Further, the first rod-shaped protrusions are arranged with a shift for each row so that no gap is generated when viewed from the width direction of the main body portion. Thereby, when the hair is combed along the width direction of the main body portion, the hair is pressed against the warmed first rod-shaped protrusions while being stretched. Thereby, it is easy to correct the hair habit.

[0009] The hair dryer according to claim 2 is the hair dryer according to claim 1, wherein the first rod-shaped protrusions have a flat shape that is long in the width direction of the main body portion, and include a metal portion whose side surface along the width direction is coated with ore.

[0010] In the hair dryer according to claim 2, the first rod-shaped protrusions have a flat shape that is long in the width direction of the main body portion. Therefore, for example, compared with protrusions having a perfect circular shape, the area where the hair contacts the first rod-shaped protrusions is large. Therefore, the effect of correcting the habit is large.

[0011] Further, since the first rod-shaped protrusions include a metal portion, the thermal conductivity is higher than that of resin, and it is easy to warm the hair. Further, since the side surface of the metal portion is coated with ore, the hair can also be warmed by radiant heat. Thereby, even if the temperature of the warm air is lowered, a drying effect can be obtained, and it is difficult to damage the hair.

[0012] The hair dryer according to claim 3 is the hair dryer according to claim 2, wherein the tip side of the first rod-shaped protrusion is further from the metal part, and the second rod-shaped protrusion is formed of resin.

[0013] In the hair dryer according to claim 3, by making the part that directly touches the human skin a resin with a low thermal conductivity, the temperature when touching the human skin can be lowered.

Effect of the Invention

[0014] According to the present invention, it is easy to correct hair habits.

[0020] An air supply port 22 for taking in air from the outside of the hair dryer 10 to the inside of the main body 20 is provided on the rear end side of the grip portion 21 in the main body 20. The air supply port 22 is an opening provided on the side surface of the main body 20, is formed along the longitudinal direction (X direction) of the main body 20, and a plurality of them are arranged in the circumferential direction of the main body 20.

[0021] A bush base 24 to which a power cord (not shown) is connected is fixed to the rear end surface of the main body 20. Power is supplied from the power cord to the heater and the motor of the hair dryer 10.

[0022] As shown in FIG. 2, an operation unit 28 is arranged on the side surface of the tip side of the grip portion 21 in the main body 20. As an example, the operation unit 28 includes a power button for driving and stopping the motor as it is pressed down. In addition, the operation unit 28 includes a switching button for driving and stopping the heater as it is pressed down. Further, the operation unit 28 may include an adjustment button that can change the output of the motor as it is pressed down.

[0023] On the tip surface of the main body portion 20, a detachable button 26 is arranged to make the brush portion 30 detachable as it is pushed down.

[0024] (Brush portion) The brush portion 30 of the present embodiment functions as a straightening iron brush that can dry hair with warm air and set or correct hair with far-infrared rays while combing hair. The brush portion 30 is detachably attached to the side surface of the tip side of the gripping portion 21 in the main body portion 20, on the side opposite to the side where the operation portion 28 is arranged.

[0025] As shown in FIG. 1, the brush portion 30 includes a base 32 and a brush unit 34 fixed to the base 32. The base 32 and the brush unit 34 are fixed to each other and can be integrally removed from the main body portion 20.

[0026] The brush unit 34 is configured to include an iron portion 34A and an outer peripheral portion 34B.

[0027] (Brush portion - Iron portion) The iron portion 34A includes a metal base (not shown), a protrusion 50, a resin base 40, and a covering portion 41.

[0028] The metal base is covered by the resin base 40 and is not visible from the outside, and is heated by the heater of the hair dryer 10. The protrusion 50 protrudes from the metal base and is integrally formed with this base. That is, the protrusion 50 is also made of metal. The protrusion 50 is warmed by heat conduction from the heated metal base.

[0029] The resin base 40 covers the metal base and constitutes the exposed bottom surface of the brush unit 34, and is integrally formed with the covering portion 41. The covering portion 41 stands upright along both sides in the width direction of the protrusion 50 from the base 40 and is connected at the upper part of the protrusion 50.

[0030] In the following description, a rod-shaped protrusion formed by a metal protrusion 50 and a resin coating portion 41 is referred to as a first rod-shaped protrusion 42. In the first rod-shaped protrusion 42, the coating portion 41 covering the tip side of the protrusion 50 is formed in a spherical shape.

[0031] In the protrusion 50, the side surfaces on both sides in the longitudinal direction (X direction) of the main body portion 20 are not covered by the coating portion 41 and are exposed. In other words, in the first rod-shaped protrusion 42, the protrusion 50 is exposed on the end surface along the width direction (Y direction) of the main body portion 20.

[0032] In the protrusion 50, the portion not covered by the coating portion 41 is coated with ore. As the metal of the metal base (not shown) and the protrusion 50, for example, aluminum, titanium, etc. can be used in consideration of light weight and corrosion resistance. Alternatively, copper or the like can be used in consideration of thermal conductivity.

[0033] Also, as the ore for coating the protrusion 50, for example, radium, silica, etc. can be used.

[0034] The first rod-shaped protrusions 42 protrude from a metal base and a resin base 40 covering this base, and are arranged side by side along the longitudinal direction (X direction) of the main body portion 20. Further, the first rod-shaped protrusions 42 are provided in a plurality of rows (three rows in this embodiment) in the width direction (Y direction) of the main body portion 20. Note that the number of these rows can be appropriately adjusted according to, for example, the dimension in the width direction (Y direction) of the main body portion 20.

[0035] As shown in FIG. 3, the plurality of rows of first rod-shaped protrusions 42 are arranged shifted for each row so that no gap occurs when viewed from the width direction (Y direction) of the main body portion 20.

[0036] Specifically, the center lines CL1 and CL2 of the first rod-shaped protrusions 42 arranged in two adjacent columns are displaced (in other words, not coincident) when viewed from the width direction of the main body 20. Further, when viewed from the width direction of the main body 20, the first rod-shaped protrusions 42 in one of the two adjacent columns are arranged at positions overlapping the gap R1 between the first rod-shaped protrusions 42 in the other column.

[0037] Further, the first rod-shaped protrusion 42 has a flat shape that is long in the width direction (Y direction) of the main body 20 when viewed from above (viewed from the direction along the axial direction of the first rod-shaped protrusion 42).

[0038] (Brush part - Outer peripheral part) As shown in FIG. 1, the outer peripheral part 34B is a part provided on the outer periphery of the iron part 34A, and is configured to include a resin base 60 and a second rod-shaped protrusion 62. The base 60 is a part that constitutes the exposed bottom surface of the brush unit 34, and is integrally formed with the base 40 of the iron part 34A.

[0039] The second rod-shaped protrusion 62 is a rod-shaped protrusion that protrudes from the base 60 and is arranged so as to surround the first rod-shaped protrusion 42. The second rod-shaped protrusion 62 is integrally formed with the base 60. That is, the base 40 and the covering part 41 of the iron part 34A, and the base 60 and the second rod-shaped protrusion 62 of the outer peripheral part 34B are integrally formed by resin.

[0040] As shown in FIG. 3, the second rod-shaped protrusion 62 has a circular shape when viewed from above (viewed from the direction along the axial direction of the first rod-shaped protrusion 42).

[0041] As shown in FIG. 4, the second rod-shaped protrusion 62 is higher than the first rod-shaped protrusion 42 of the iron part 34A. Further, the height of the second rod-shaped protrusion 62 gradually increases from the central part to both ends in the longitudinal direction (X direction) of the outer peripheral part 34B. The tip of the second rod-shaped protrusion 62 is formed in a spherical shape.

[0042] (Blowout port) As shown in FIG. 3, a blowing port 70 is provided in the base 60 of the outer peripheral portion 34B. The blowing port 70 is an opening capable of blowing cold air and warm air to the outside of the brush portion 30. In a top view (viewed from a direction along the axial direction of the first rod-shaped protrusion 42), the blowing port 70 is provided inside the second rod-shaped protrusion 62 and outside the first rod-shaped protrusion 42.

[0043] The blowing port 70 has an oval shape along the longitudinal direction (X direction) of the main body portion 20, and a plurality (four in this embodiment) are arranged side by side in the longitudinal direction of the main body portion 20. Further, the blowing ports 70 are arranged on both sides in the width direction (Y direction) of the main body portion 20.

[0044] Also, a blowing port 72 is provided on the rear end side of the iron portion 34A in the longitudinal direction of the main body portion 20.

[0045] Below the brush portion 30 and directly below the blowing port 70, a red LED bulb 80 is provided. Also, below the brush portion 30 and directly below the blowing port 72, an outlet 82 capable of discharging negative ions to the outside of the brush portion 30 is arranged. The red LED bulb 80 and the outlet 82 are fixed to the main body portion 20 and remain in the hair dryer 10 even when the brush portion 30 is removed.

[0046] <Operation and Effect> In the hair dryer 10 according to the embodiment of the present invention, the base 40 of the iron portion 34A shown in FIG. 1 is heated and the first rod-shaped protrusion 42 is warmed. Thereby, the hair can be combed while being warmed.

[0047] Also, as shown in FIG. 3, the first rod-shaped protrusions 42 are arranged shifted for each row so that there is no gap when viewed from the width direction of the main body portion 20. Thereby, when the hair is combed along the width direction of the main body portion 20, the hair is pressed against the warmed first rod-shaped protrusions 42 while being stretched. Thereby, it is easy to correct the habit of the hair.

[0048] In addition, in this hair dryer 10, the first rod-shaped protrusion 42 has a flat shape that is long in the width direction of the main body 20. Therefore, for example, compared with a protrusion having a perfect circular shape, the area of the hair contacting the first rod-shaped protrusion 42 is large. Therefore, the effect of correcting the habit is great.

[0049] In addition, since the first rod-shaped protrusion 42 includes a metal protrusion 50, the thermal conductivity is higher than that of resin, and it is easy to warm the hair. Further, since the side surface of the protrusion 50 is coated with ore, the hair can also be warmed by radiant heat. Thereby, even if the temperature of the warm air is lowered, a drying effect can be obtained, and it is difficult to damage the hair.

[0050] In addition, in this hair dryer 10, as shown in FIG. 1, in the first rod-shaped protrusion 42, the tip side of the metal protrusion 50 and the second rod-shaped protrusion are formed of resin. In this way, by using resin with a low thermal conductivity for the part that directly touches the human skin, the temperature when touching the human skin can be lowered compared with the case where the part is formed of metal.

[0051] In addition, in this hair dryer 10, below the air outlet 70, a red LED bulb 80 and an outlet 82 capable of discharging negative ions to the outside of the brush part 30 are arranged.

[0052] By arranging the red LED bulb 80, the scalp can be irradiated with red light, and the cells of the scalp can be activated. In addition, by discharging negative ions from the outlet 82, water molecules can be collected. These water molecules are warmed by the vibration of the far-infrared rays radiated from the ore-coated protrusion 50 and easily penetrate into the hair. Thereby, it is easy to keep the hair moist.

[0053] In addition, in this hair dryer 10, the brush part 30 is detachable. Thereby, for example, an attachment without a brush such as the first rod-shaped protrusion 42 or the second rod-shaped protrusion 62, or an attachment having a brush such as the second rod-shaped protrusion 62 but not having the iron part 34A can be attached and used.

[0054] <Other Embodiments> In the above embodiment, the first rod-shaped protrusion 42 has a flat shape that is long in the width direction of the main body 20, but the embodiments of the present invention are not limited to this. For example, the first rod-shaped protrusion 42 may have a circular shape with the same dimensions in the width direction and the longitudinal direction of the main body 20.

[0055] Also, in the above embodiment, the first rod-shaped protrusion 42 includes the metal protrusion 50 coated with ore, but the embodiments of the present invention are not limited to this. For example, the protrusion 50 may not be coated with ore.

[0056] Also, the first rod-shaped protrusion 42 may not include the protrusion 50. In this case, the first rod-shaped protrusion 42 made of resin including the portion formed by the protrusion 50 may be coated with ore, or the coating may be omitted.

[0057] Also, in the above embodiment, the outer peripheral portion 34B including the second rod-shaped protrusion 62 is provided on the outer periphery of the iron portion 34A, but the embodiments of the present invention are not limited to this. For example, the outer peripheral portion 34B may be omitted.

[0058] Also, in the above embodiment, the red LED bulb 80 and the discharge port 82 are arranged below the blowout port 70, but the embodiments of the present invention are not limited to this. These red LED bulbs 80 and the discharge port 82 may be omitted.

[0059] Even in such various embodiments, by providing a plurality of rows of the first rod-shaped protrusions 42 and arranging them shifted for each row so that no gap is generated when viewed from the width direction of the main body 20, an effect of easily correcting hair habits can be obtained.

[0060] Note that, as described above, the brush unit 30 is a unit member detachably attached to the main body unit 20. By removing the brush unit 30 from the main body unit 20, for example, as shown in FIG. 5, a blowing unit 90, which is another unit member, can be attached. The blowing unit 90 does not include a brush (rod-shaped protrusion) for combing hair. Further, the blowing unit 90 includes a blowing port through which air blown out from the blowout ports 70 and 72 can be blown out. Since the blowing unit 90 does not include a brush (rod-shaped protrusion), it functions as a hair dryer. According to the present embodiment, by replacing the brush unit 30 with the blowing unit 90, the weight of the hair dryer 10 can be reduced as compared with the case where the brush unit 30 is used.

[0061] Further, instead of the brush unit 30 and the blowing unit 90, a curling brush (not shown), which is another unit member, may be attached to the main body unit 20. Also in this case, the weight of the hair dryer 10 can be reduced as compared with the case where the brush unit 30 having an ironing unit is used.
