Detailed Description
Embodiments of the present invention will be described below with reference to the drawings. In the following description, the same components are given the same reference numerals. Their names and functions are also the same. Therefore, detailed description thereof will not be repeated.
< first embodiment >
In the present embodiment, a hair dryer (hair dryer) to which a fitting as an example of the attachment of the present invention is attached will be described as an example. In addition, the hair dryer with the attached accessories is used not only for drying hair but also for massaging hair and scalp, and the like. That is, the hair dryer with the attachment also has a function of caring hair and scalp. Therefore, the hair dryer with the accessory mounted thereto is also referred to as a hair care device or a scalp care device.
(Hair care device and Hair dryer configuration)
First, a schematic configuration of the hair care device 1 according to the present embodiment will be described with reference to fig. 1. As shown in fig. 1, the hair care device 1 is mainly composed of a fitting (mount) 2 and a blower 3. The attachment 2 is used by being attached to an air outlet (delivery port) 59 (see fig. 4) of the blower 3.
The metal fitting 2 is mainly composed of a main body 11 and a protrusion 12 protruding from the main body 11. As shown in fig. 3, the protrusion 12 has a plurality of (5 in the present embodiment) protrusions, and has the following shape: the shape of the fingers is simulated when the scalp is massaged with a human hand. The tips of the protrusions 12 are provided with contact portions 21 that come into contact with the scalp or hair (treated part) of the user when the hair care device 1 is used (treated). The contact portion 21 has a spherical shape slightly expanded from the other portions, like the tip of a match stick. This can enlarge the contact area of the contact portion with respect to the scalp during treatment. Further, the scalp can be made to feel better when the protruding portion 12 is in contact with the scalp. More specific configuration of the fitting 2 will be described later.
The blower 3 has a substantially cylindrical shape. Fig. 4 shows an external configuration of a single blower 3. The blower 3 is mainly constituted by a housing formed of plastic or the like.
The blower 3 is provided with an air inlet 57 and an air outlet 59 at each end in the longitudinal direction of the substantially cylindrical shape. For convenience of description, the side where the suction port 57 is provided is referred to as a lower end portion of the blower 3, and the side where the discharge port 59 is provided is referred to as an upper end portion of the blower 3.
The side surface of the housing is provided with an operation portion 58. When the blower 3 is used, the user operates the operation portion 58 to start or stop the operation of the blower 3. Further, the type of air (warm air/cool air) blown out from the air outlet 59, the air volume, and the like are adjusted by operating the operation unit 58.
A power cord 60 is provided at the lower end (suction port 57 side) of the blower 3.
Fig. 2 shows the internal structure of the hair care device 1. The blower 3 includes a warm air generating unit 51, an ion supplying unit (charged particle generating device) 52, and the like.
The warm air generating unit 51 includes, as main components, a fan 54, a heater 53, and a motor 56 for driving the fan 54. When the blower 3 is operated, the fan 54 is rotated by the driving force of the motor 56. Thus, an air flow from the suction port 57 toward the discharge port 59 is formed inside the blower 3.
In addition, when the blower 3 is operated, the heater 53 is operated, whereby the air introduced into the inside of the blower 3 is heated. Thereby, warm air is sent out from the air outlet 59. Further, when the blower 3 is operated, the operation of the heater 53 may also be stopped. In this case, cool air is sent out from the air outlet 59.
The ion supply unit 52 is attached to the inner wall of the cylindrical housing. The ion supply unit 52 is disposed in the vicinity of the outlet 59.
The ion supply part 52 generates positive (+) ions (e.g., H)+(H2O)m(m is an arbitrary natural number)) and a negative (-) ion (e.g., O2 -(H2O)n(n is an arbitrary natural number). In the present embodiment, the ion supply unit 52 releases both positive ions and negative ions. By providing the blower 3 with the ion supply unit 52, ions can be contained in the air blown out from the blower 3. By adding ions to the air blown from the blower 3, moisture can be supplied to the treated hair and scalp, and keratin denaturation in the hair can be suppressed. This can further improve the hair and scalp care effect.
In addition, H+(H2O)mAnd O2 -(H2O)nAttached to the surface of airborne bacteria in the air, chemically reacts and generates H as an active group2O2Or OH (hydroxyl radical). Due to H2O2Or OH exhibits a very strong activity, so that it can surround and inactivate molds and miscellaneous bacteria as airborne bacteria and be removed. Therefore, the air blown out from the blower 3 can be made into a cleaner state. As the ion supply unit 52, for example, an ion generator disclosed in patent document 2 (japanese patent application laid-open No. 2013-102826) is used.
An ion supply port 55 is provided at an end of the ion supply portion 52 closer to the blow-out port 59. Thereby, the ions (positive ions and negative ions) generated by the ion supply unit 52 can be blown out from the blowoff port.
In another embodiment of the present invention, a blower having an ion supply unit that generates only negative ions may be used. In this case, the same configuration as that of the present embodiment can be applied.
The charged particle generating device provided in the hair dryer according to the aspect of the present invention is not limited to the ion supply unit, and may be any discharge device that generates ions, electrons, ozone, radicals, active radicals, and the like by electric discharge. When the charged particle generating device generates ions, both positive ions and negative ions may be generated, or either positive ions or negative ions may be generated.
With the above configuration, air can be blown out from the air outlet 59 of the blower 3. By placing the blowing port 59 of the blower 3 near the hair, the wind from the blowing port 59 can be blown toward the hair. Thereby, the hair can be dried.
Further, since the blower 3 includes the ion supply portion 52, ions can be contained in the air blown out from the air outlet 59. Thereby, an effect of caring hair and scalp can be obtained.
In the present embodiment, the fitting 2 is attached to the outlet 59 of the blower 3 having the above-described configuration. As described later, a space is formed inside the body portion 11 of the metal fitting 2. This space serves as an air passage for guiding the air blown out from the air outlet 59 of the blower 3 to the treatment area of the user and the vicinity thereof.
That is, according to the hair care device 1 of the present embodiment, the air supplied from the blower 3 can be sent mainly to the treatment site of the user through the air passage inside the attachment 2. As described above, the fitting 2 is provided with the protruding portion 12 having the contact portion 21. Therefore, the user using the hair care device 1 can massage the treated part by bringing the tip portions (i.e., the contact portions 21) of the protruding portions 12 into contact with the scalp or the hair while blowing the wind containing the ions supplied from the blower 3 to the hair or the scalp.
Note that, a fitting (for example, a brush-like fitting) having a shape other than the fitting 2 may be attached to the air outlet 59 of the blower 3. In this case, the hair may be dried while blowing the hair or setting the hair.
(constitution of the Accessories)
Next, a more specific structure of the component 2 will be described with reference to fig. 3 and 5 to 7.
Fig. 3 shows an external configuration of the fitting 2. Fig. 5 shows a state in which the respective constituent members of the fitting 2 are disassembled. Fig. 6 shows a state in which the fitting 2 is seen from the tip end (i.e., the contact portion 21) side of the protrusion portion 12. Fig. 7 shows the fitting 2 viewed from the side of the wind inlet 18.
As described above, the metal fitting 2 is mainly composed of the main body portion 11 and the protruding portion 12 protruding from the main body portion 11. As shown in fig. 3, the main body 11 has a substantially truncated cone shape. The inlet 18 and the outlets 22a and 22b, which are first outlets, are provided on the respective bottom surfaces of the substantially truncated cone shape. Specifically, an inlet 18 into which the air from the blower 3 flows is provided on the bottom surface of the truncated cone having a small area, and air outlets 22a and 22b for blowing the air to the treatment area of the hair or scalp are formed on the bottom surface of the truncated cone having a large area.
In other words, the end of the main body 11 on the inflow port 18 side is connected to the outlet 59 of the blower 3. As shown in fig. 2, the end of the body 11 on the inlet 18 side is attached to the upper end of the blower 3 so as to cover the periphery of the outlet 59 of the blower 3.
In the present specification, for convenience of description, the end of the body 11 on the side of the inlet 18 is referred to as the lower end or the lower side of the body 11 or the metal fitting 2, and the end of the body 11 on the side of the outlets 22a and 22b is referred to as the upper end or the upper side of the body 11 or the metal fitting 2. When the respective ends of the main body 11 are defined in the direction of the flow of the air passing through the blower 3, the end of the main body 11 on the side of the inlet 18 is referred to as the upstream side, and the ends of the main body 11 on the side of the outlets 22a and 22b are referred to as the downstream side.
In the present description, for convenience, the fitting 2 is defined by three coordinate axes X, Y, Z shown in fig. 3 when describing the shape, positional relationship, and the like of the respective constituent elements of the fitting 2. The X direction is a direction along a line connecting the contact portions 21a and 21e located at both side ends in each contact portion 21 of the projection 12. The Y direction is a direction orthogonal to the above-described X direction on the surface on which the air outlets 22a and 22b are formed. The Z direction is a direction orthogonal to the face on which the air outlets 22a and 22b are formed.
From the above, the air outlets 22a and 22b may be provided on the surface on the upper end side of the main body 11 (for convenience, this surface may be referred to as the front surface of the main body 11). Most of the air blown out from the blower 3 (for example, an air volume of 50% to 90% of the air volume from the blower 3) is blown out from the first blowout ports, that is, the blowout ports 22a and 22 b. That is, the air outlets 22a and 22b are the main air outlets in the hair care device 1. When the hair care device 1 is used, air is blown directly from the air outlets 22a and 22b toward the scalp or a hair treatment area of the user.
Therefore, the air outlets 22a and 22b are arranged so as to surround the protrusion forming position 15d (see fig. 5) on the front surface of the main body 11 (see fig. 3).
Here, the treatment site is a part of the scalp or hair of the user, and refers to a site that is heavily cared using the hair care device 1. For example, when the hair care device 1 is used, the portion of the fitting 2 that the respective contact portions 21 of the distal ends of the protrusions 12 contact corresponds to the treatment portion. Further, when using the hair care device 1, the user performs care (treatment) while moving the hair care device 1 relative to the scalp or hair. Thus, the treatment sites move in sequence.
Here, the region different from the treatment region means any region other than the treatment region. The periphery of the treatment site or the vicinity of the treatment site refers to a site that is included in a site different from the treatment site, but is relatively close to the treatment site (for example, within a radius of 50 cm). For example, the entire head of the user of the hair care device 1 is included around or near the treatment site.
In addition, the main body 11 is provided with a peripheral edge air outlet 23 (second air outlet) as an air outlet different from the air outlets 22a and 22 b. The peripheral edge blow-out port 23 is provided along the outer peripheral surface of the main body 11. In the present embodiment, the peripheral edge blow-out port 23 is formed over substantially half of the outer periphery of the main body 11. The peripheral edge air outlet 23 is located closer to the lower end side of the main body 11 than the air outlets 22a and 22 b.
According to this configuration, when the hair care device 1 is used, the wind from the peripheral edge blow-out port 23 is blown to a region different from the treatment region. Specifically, the air blown out from the peripheral edge blow-out port 23 is configured to flow around the treatment site or in the vicinity of the treatment site.
As described above, in the present embodiment, the air blown out of the blower 3 passes through the main body 11, and at least a part of the air is blown to a portion different from the treatment portion.
The fitting 2 is formed by assembling a plurality of constituent members. Hereinafter, each constituent member constituting the accessory 2 is explained with reference to fig. 5.
In the present embodiment, the fitting 2 is disassembled into the cylindrical member 13, the air path forming member 14, the tip member 15, and the cover member 16. Of these members, the main body 11 is formed of a cylindrical member 13, an air path forming member 14, a part of the tip member 15, and a cover member 16. In addition, a protrusion 12 is formed on a part of the tip member 15. In the present embodiment, each component is formed of a resin material (for example, plastic or the like) having a lower thermal conductivity than metal. However, the material of each constituent member is not limited thereto.
The tubular member 13 mainly forms the outer shape of the main body 11 in a cylindrical shape (more specifically, a bell-mouth shape). The tubular member 13 has an outer peripheral surface 31, an inner peripheral surface 32, a recess 33, and the like. The inner peripheral surface 32 forms an air passage through which air from the blower 3 passes.
The concave portion 33 is present at a position recessed inward by one step from the outer peripheral surface 31. The recess 33 is covered with a cover member 16 described later. In the recessed portion 33, an opening 33a is formed near the boundary of the outer peripheral surface 31. Thereby, a part of the wind passing through the inner side of the inner circumferential surface 32 flows toward the recess 33 through the opening 33 a.
The air passage forming member 14 is fitted into the cylindrical member 13 (inner circumferential surface 32). The air path forming member 14 includes a curved plate portion 34 (air receiving portion), an air volume regulating portion 35, an insertion hole 36, and the like. The curved plate portion 34 divides the air passage formed by the inner peripheral surface 32 of the tubular member 13 into 2 air passages.
Specifically, the curved plate portion 34 divides the air passage into a first air passage P1 that guides the air from the blower 3 to the air outlets 22a and 22b around the protrusion 12 and a second air passage P2 that guides the air to the peripheral edge air outlet 23 (see fig. 2, 7, 10, and the like). Further, the curved plate portion 34 also functions as a blocking member that blocks a part of the wind blown out from the blower 3 (particularly, the wind on the side of the temperature peak) from flowing toward the air outlets 22a and 22 b.
The air volume regulating portion 35 is disposed at a position corresponding to the central portion of the contact portions 21a to 21e (the position at which the contact portion 21c is disposed) arranged substantially in a line along the X direction. This can reduce the volume of air blown out from the periphery of the contact portion 21c in the central portion, of the air blown out from the air outlet 22b through the first duct P1 in the main body 11. According to this configuration, since the volume of air reaching the treatment site of the user at the shortest distance is reduced, the sensible temperature of the user when warm air is blown can be reduced.
Further, by providing the air volume restrictor 35, the air blown out from the outlet port 22b through the first duct P1 in the main body 11 can be divided into two sides of the air volume restrictor 35 (see fig. 11).
The insertion holes 36 are provided at both ends of the bent plate portion 34, respectively, and extend so as to protrude toward the tip member 15 side. The insertion portion 15c of the tip member 15 is inserted into the insertion hole 36. Thereby, the tip member 15 is fixed and constitutes a part of the main body 11.
The tip member 15 constitutes the front surface of the main body 11. The front surface is provided with a first wall 15a, a second wall 15b, an air outlet 22a, an air outlet 22b, and the like. Further, the tip member 15 is provided with a protrusion 12 so as to protrude from the front surface. Each projection of the projection portion 12 extends substantially in the Z direction from a projection portion forming position 15d on the front surface. The tip of each projection of the projection 12 is provided with a contact portion 21.
The configuration of the front surface of the tip member 15 is explained with reference to fig. 6. Here, for convenience of explanation, the positional relationship of the components will be described in the directions of arrows X and Y shown in fig. 6. However, the hair care device 1 is not limited to be used in this positional relationship.
The front surface of the tip member 15 has a substantially circular shape. The contact portions 21 of the protrusion 12 are arranged in a row so as to intersect the front surface in the X direction. In the present embodiment, the contact portions 21 of the projection 12 are not arranged linearly, but 3 contact portions 21b, 21c, and 21d located at the middle of the rows are arranged with a slight shift in the arrow Y direction (upward direction in the drawing). That is, the contact portions 21 are arranged so as to draw an arc as a whole.
The first wall portion 15a and the second wall portion 15b sandwich the contact portion 21c located at the center and are located on both sides in the Y direction, respectively. That is, in fig. 6, the first wall portion 15a is located above the contact portion 21c, and the second wall portion 15b is located below the contact portion 21 c.
Fig. 7 shows a state of the fitting 2 viewed from the inflow port 18 side. As shown in fig. 7, the air flowing in from the inlet is divided into two passages (i.e., the first passage P1 and the second passage P2) by the curved plate portion 34 of the passage forming member 14. In fig. 7, the first and second passages P1 and P2 are divided vertically. The first wall portion 15a and the second wall portion 15b of the tip member 15 are positioned on the front surface of the first air passage P1 (the upper air passage in fig. 7) of the two flow passages.
This means that the first wall portion 15a and the second wall portion 15b serve as barriers against the air blown into the first air passage P1 of the accessory 2 from the air outlet 59 of the blower 3. That is, since the first wall portion 15a and the second wall portion 15b are provided, the wind blown into the first flow path P1 of the attachment 2 from the blowing port 59 of the blower 3 can be suppressed from directly blowing toward the treatment site. This can reduce the sensible temperature of the user when using the hair care device 1.
In the state shown in fig. 7, a second air passage P2 is formed in the lower portion of the interior of the main body 11. As shown in fig. 7, the curved plate portion 34 of the duct forming member 14 is disposed at a position corresponding to the second duct P2 on the front side (downstream side of the wind flow) of the main body 11 as viewed from the inlet 18 side. This means that the forward travel of the wind flowing from the inflow port 18 into the lower portion inside the main body 11 is blocked by the curved plate portion 34. That is, the wind flowing through the second air passage P2 is blocked by the bent plate portion 34 from traveling forward, and flows toward the opening 33a formed in the lower side of the tubular member 13.
Further, the front surface of the front end member 15 has an air outlet 22a and an air outlet 22b formed at positions other than the positions where the first wall portion 15a and the second wall portion 15b are formed. As shown in fig. 6, the air outlet 22a and the air outlet 22b are disposed in the Y direction (vertical direction in fig. 6) with the formation position of the protrusion 12 therebetween.
Specifically, in the state shown in fig. 6, the air outlet 22a is located above the projection forming position. The air outlets 22a are formed on both sides of the first wall portion 15a, and the first wall portion 15a is formed in the center in the X direction. In the state shown in fig. 6, the air outlet 22b is located below the projection forming position. In the state shown in fig. 6, the air outlet 22b is formed to occupy most of the lower portion of the front surface of the front end member 15. Further, the curved plate portion 34 of the air path forming member 14 is positioned on the back side of the air outlet 22b when viewed from the front of the treatment site (or the contact portion 21) (see fig. 6).
As described above, in the present embodiment, when the accessory 2 is viewed from the treatment site (or the contact portion 21), the inlet 18 into which the wind from the blower 3 flows is hidden by being covered with the members constituting the main body (specifically, the first wall portion 15a, the second wall portion 15b, the curved plate portion 34, and the like) (see fig. 6). When the interior of the body portion 11 of the metal fitting 2 is viewed from the inlet 18 side, the front side is shielded by the members constituting the body portion (specifically, the first wall portion 15a, the second wall portion 15b, the curved plate portion 34, and the like) (see fig. 7).
The cover member 16 has a shape in which a substantially plate-like member is curved so as to describe an arc. The cover member 16 has an outer peripheral surface 37 and an inner peripheral surface 38. The cover member 16 is attached to the cylindrical member 13 so as to cover a part of the outer periphery of the cylindrical member 13 (specifically, the recess 33). In the present embodiment, a cover member 16 is attached to the outer peripheral portion of the cylindrical member 13 on the side of the distal end member 15 where the first wall portion 15a is formed.
In a state where the cover member 16 is attached to the tubular member 13, the recess 33 of the tubular member 13 forms a space between the inner peripheral surface 38 of the cover member 16. This space leads from the opening portion 33a to the peripheral edge blow-out port 23, and constitutes a part of the second air passage P2.
(about the flow of wind within the fitting)
Next, the flow of wind in the attachment 2 will be described with reference to fig. 2, 8 to 12. Fig. 8 and 9 show the fitting 2 with the cover member 16 removed, and show the flow of wind therein. Fig. 10 shows a sectional configuration of the fitting 2 and shows the flow of wind there. Fig. 11 and 12 show the attachment 2 with the tip member 15 removed, and show the flow of wind in the main body 11. In the drawings, a solid arrow indicates the wind W1 in the first air passage P1, and a broken arrow indicates the wind W2 in the second air passage P2.
As shown in fig. 2, the main body 11 is hollow. This space in the main body 11 forms an air passage for guiding the air from the blower 3 to the treatment site of the user and the vicinity thereof. As described above, in the present embodiment, two air passages (the first air passage P1 and the second air passage P2) are substantially present inside the main body 11.
The first air passage P1 is an air passage that guides the air from the blower 3 to the outlets 22a and 22 b. In other words, the first duct P1 can be said to be a duct that guides the air blown out from the air outlet 59 of the blower 3 to the treatment site substantially along the blowing direction.
The second air passage P2 is an air passage that guides the air from the blower 3 to the peripheral edge outlet 23. In other words, the second air passage P2 can be said to be an air passage that guides the air from the blower 3 to a location other than the treatment site.
The flow of the air in the first air passage P1 will be described in order from the upstream side. As shown in fig. 12, a part of the wind flowing into the main body 11 of the attachment 2 through the inlet 18 flows into the opposite side (upper side in fig. 12) to the position where the air path forming member 14 is disposed. The wind becomes wind W1 flowing through the first air passage P1.
As shown in fig. 10, the wind W1 flows toward the distal end member 15 side inside the tubular member 13. The inner peripheral surface 32 of the cylindrical member 13 has a bell mouth shape, and the inner diameter thereof gradually increases toward the tip member 15 in which the air outlets 22a and 22b are formed. That is, the first air passage P1 through which the wind W1 passes expands toward the downstream side.
At this time, as shown in fig. 11, the wind W1 is directed toward the air outlet 22a and also toward the air outlet 22 b. Most of the wind heading toward the air outlet 22b flows along the curved plate portion 34. The wind flowing along the curved plate portion 34 is divided into W1a and W1b by the wind volume restriction portion 35. This can reduce the volume of air blown out from the center portion of the air outlet 22b in the X direction.
Further, the inner peripheral surface 32 of the cylindrical member 13 constituting the wall surface of the first air passage P1 is curved in the flow direction of the wind. The curved portion 34 of the air passage forming member 14 constituting a part of the wall surface of the first air passage P1 also has a smooth curved surface whose surface is along the flow direction of the wind. This reduces the loss of the air volume passing through the first duct P1.
The flow of the air in the second air passage P2 will be described in order from the upstream side.
Part of the wind flowing into the main body 11 of the attachment 2 through the inlet 18 flows into the side where the air passage forming member 14 is disposed. This wind becomes wind W2 (see fig. 10) flowing through the second air passage P2.
As shown in fig. 10, the wind W2 is prevented from traveling toward the tip member 15 by the bent plate portion 34. Thereby, the wind W2 flows toward the opening 33a formed in the recess 33 of the tubular member 13 (see fig. 8 and 9). The wind W2 that has flowed into the opening 33a passes through the space formed between the recess 33 of the tubular member 13 and the inner circumferential surface 38 of the cover member 16, and is blown out from the peripheral edge blow-out port 23 (see fig. 10).
As described above, in the fitting 2 according to the present embodiment, part of the air flowing into the inlet 18 from the outlet 59 of the blower 3 can be blown out from the outlets 22a and 22b provided around the protrusion 12, and another part of the air flowing into the inlet 18 can be blown out from the peripheral outlet 23. The wind W1 blown out from the air outlets 22a and 22b is blown out toward the user's treatment site, while the wind W2 blown out from the peripheral edge air outlet 23 is blown out toward a position different from the treatment site (for example, the periphery of the user's head).
As described above, according to the attachment 2 of the present embodiment, a part of the air flowing into the inlet 18 from the outlet 59 of the blower 3 can be blown out toward the treatment site. Therefore, the heat of the wind blowing the treatment site can be reduced as compared with the case where all the wind flowing into the inlet 18 is blown to the treatment site. Therefore, when the hair care device 1 is used, the user can be suppressed from feeling hot when the contact portion 21 of the attachment 2 is brought into contact with the scalp or the like to perform massage or the like. Therefore, the comfort in use is improved.
In addition, in the attachment 2 according to the present embodiment, the first wall portion 15a and the second wall portion 15b are provided at substantially the center portion of the front surface of the distal end member 15 facing the treatment site. By providing the first wall portion 15a and the second wall portion 15b, the straight blow-out of wind can be suppressed. This can prevent the wind blowing into the first air passage P1 of the attachment 2 from directly blowing toward the treatment site. Therefore, the temperature of the wind blowing to the treatment site can be further reduced, and the comfort during use can be further improved. Further, the first air passage P1 expands as it goes toward the air outlets 22a and 22 b. With this configuration, the temperature of the air blown to the treatment site can be further reduced.
In the accessory 2 according to the present embodiment, the air W2 that has passed through the second air passage P2 is blown out from the peripheral edge blow-out port 23. The peripheral edge blow-out port 23 has a blow-out surface substantially parallel to the front surface of the front end member 15. However, the blowing direction of the wind from the peripheral air outlet 23 is slightly shifted outward from the blowing directions of the air outlets 22a and 22 b. Thereby, a part of the wind of the blower 3 can be blown to a position different from the treatment site (for example, the vicinity of the treatment site). The attachment to the treatment area contains the entire head of the user. Therefore, it is possible to apply a breeze containing ions to the head and all of the hair while performing treatment (massage or the like) of the treatment site using the hair care apparatus 1.
(mounting position of the fitting with respect to the blower)
Next, a positional relationship between the internal structure of the blower 3 and each component of the accessory 2 in a state where the accessory 2 is attached to the blower 3 will be described with reference to fig. 13. Fig. 13 shows a cross-sectional structure of the accessory 2 in a state where the accessory 2 is attached to the blower 3, and a schematic structure of the inside of the blower 3.
Fig. 13 is a cross-sectional view of the metal fitting 2 shown in fig. 6 cut along the Y direction at the center in the X direction. In fig. 13, for convenience of explanation, the direction toward the right in the drawing is referred to as the Y1 direction, and the direction toward the left in the drawing is referred to as the Y2 direction.
As described above, the interior of the main body 11 of the accessory 2 is divided into the first air passage P1 and the second air passage P2. In fig. 13, the first air passage P1 is located on the Y1 side, and the second air passage P2 is located on the Y2 side. Further, the peripheral edge outlet 23 of the second air passage P2 is located at the end on the Y1 side.
As described above, the blower 3 includes the warm air generating unit 51, the ion supply unit 52, and the like. As shown in fig. 13, the warm air generating unit 51 is disposed on the Y2 side near the inside of the blower 3. Further, the ion supply unit 52 is attached to the side wall of the blower 3 on the Y1 side.
The warm air is blown out substantially perpendicularly from the warm air generation unit 51 toward the blow-out surface of the blow-out port 59. Further, the temperature of the warm air blown out from the warm air generating portion 51 shows the distribution shown by the solid line in fig. 13 along the arrangement position thereof. That is, a temperature peak of the warm air exists in a substantially central portion of the arrangement position of the warm air generating unit 51.
The ion supply portion 52 discharges ions from the ion supply port 55 toward the blow port 59. Further, the concentration of ions released from the ion supply port 55 shows a distribution shown by a broken line in fig. 13 along the arrangement position of the ion supply port 55. That is, the ion concentration peak exists at a position corresponding to the ion supply port 55.
In the hair care device 1 of the present embodiment, as shown in fig. 13, the ion supply portion 52 (more specifically, the ion supply port 55) of the blower 3 is disposed so as to correspond to the first air passage P1 of the attachment 2. That is, the ion supplier 52 and the first air passage P1 are disposed close to the Y1 side.
With the above configuration, the wind including ions of a higher concentration in the wind blown out from the blower 3 can be guided toward the first flow path P1. This makes it possible to include more ions in the air blown from the air outlets 22a and 22b to the treatment site.
In the hair care device 1 of the present embodiment, the warm air generator 51 of the blower 3 is disposed so as to correspond to the second air passage P2 of the attachment 2. That is, the warm air generator 51 and the second air passage P2 are disposed closer to the Y2 side.
With the above configuration, the wind having a higher temperature of the wind blown out from the blower 3 can be guided to the second duct P2 side. The air passing through the second air passage P2 changes its direction in the main body 11, and is finally blown out from the peripheral edge blow-out port 23 to a position different from the processing portion. Thus, the wind having a relatively high temperature is blown to a position other than the treatment site. The second air passage P2 is formed to detour inside the main body 11. Therefore, the temperature of the air passing through second air passage P2 tends to decrease to some extent before reaching peripheral edge blowout port 23.
In the hair care device 1 of the present embodiment, the bent plate portion 34 is disposed in the main body portion 11 of the attachment 2 at a position at least partially overlapping the position where the warm air generating portion 51 is disposed when viewed from the front of the air outlet 59 of the blower 3. By providing the curved plate portion 34, the high-temperature wind directly blowing from the warm air generating portion 51 into the interior of the main body portion 11 of the metal fitting 2 is blocked by the curved plate portion 34 and is not blown out from the blowing ports 22a and 22 b. That is, the bent plate portion 34 can provide a wind receiving effect of blocking high-temperature wind directly blown from the warm air generating portion 51 into the main body portion 11 of the metal fitting 2.
With the above configuration, the air having a relatively low temperature of the air blown out from the blower 3 can be blown out preferentially from the first duct P1 to the air outlets 22a and 22 b. Thereby, the comfort of the user can be improved when using the hair care device 1.
In the hair care device 1 of the present embodiment, the ion supply portion 52 is preferably disposed at a position different from the position at which the bent plate portion 34 of the attachment 2 is disposed (i.e., at a position not overlapping with the position at which the bent plate portion 34 is disposed) when viewed from the front of the outlet port 59 of the hair dryer 3. Accordingly, of the air blown out from the blower 3, the air containing a higher ion concentration can be blown out to the blow-out ports 22a and 22b preferably from the first duct P1. This makes it possible to supply more ions to the treatment site.
(summary of the first embodiment)
As described above, the attachment 2 according to the present embodiment is used by being attached to the blower 3. The metal fitting 2 has a main body portion 11 and a protrusion portion 12 protruding from the main body portion 11. The main body 11 has a plurality of air outlets ( air outlets 22a and 22b, and peripheral air outlets 23). In addition, air passages (a first air passage P1 and a second air passage P2) leading from the inlet 18 to the respective outlets are formed inside the main body 11. The protrusion 12 has a plurality of contact portions 21 that contact the treatment site.
The first air passage P1 in the main body 11 guides the air from the blower 3 to the air outlets 22a and 22 b. The air outlets 22a and 22b are provided around the projection 12. Therefore, the wind directly toward the treatment site is blown out from the air outlets 22a and 22 b.
The second air passage P2 in the main body 11 guides the wind from the blower 3 to the peripheral edge blow-out port 23. The peripheral edge blow-out port 23 is disposed on the outer periphery of the main body 11. Therefore, the air blown out from the peripheral edge blow-out port 23 travels in a direction away from the protruding portion 12. That is, the air directed to a position other than the treatment site is blown out from the peripheral edge blow-out port 23.
As described above, the air blown out from the blower 3 passes through the main body portion 11, and at least a part thereof is blown to a portion different from the treatment portion. Specifically, the air blown out from the peripheral edge blow-out port 23 is configured to flow around the treatment site or in the vicinity of the treatment site.
That is, according to the accessory 2 of the present embodiment, a part of the air flowing into the inlet 18 from the outlet 59 of the blower 3 is blown out toward the treatment site. Therefore, the heat of the wind blowing the treatment site can be reduced as compared with the case where all the wind flowing into the inlet 18 is blown to the treatment site. Therefore, when the contact portion 21 of the attachment 2 is brought into contact with the scalp or the like to perform massage or the like, the user can be suppressed from feeling hot. Therefore, the comfort in use is improved.
< second embodiment >
Next, a second embodiment of the present invention will be described. In the first embodiment, the hair care device 1 in which the attachment 2 is attached to the hair dryer 3 including the ion supply unit 52 is explained as an example. However, the accessory according to one aspect of the present invention may be attached to a blower that does not include an ion supply unit. Therefore, the hair care device 101 in which the accessory 2 is attached to the blower 103 having no ion supply unit will be described below as an example.
Fig. 14 shows an internal configuration of the hair care device 101 according to the second embodiment. As shown in fig. 14, the hair care device 101 is mainly composed of a fitting (mount) 2 and a blower 103. As in the first embodiment, the attachment 2 is used by being attached to an air outlet (delivery port) 59 of the blower 103.
The same configuration as that of the first embodiment can be applied to the configuration of the fitting 2. Therefore, a detailed description of the fitting 2 is omitted. Fig. 14 shows a cross-sectional structure of the accessory 2 in a state where the accessory 2 is attached to the blower 103, and a schematic structure of the inside of the blower 103.
The blower 103 includes a warm air generating unit 51 and the like therein. The warm air generating unit 51 includes a fan 54, a heater 53, a motor (not shown), and the like, as in the first embodiment. The blower 103 according to the present embodiment does not include an ion supply unit. The blower 103 is basically the same in configuration as the blower 3 of the first embodiment, except that it does not have an ion supply portion.
In fig. 14, for convenience of explanation, the direction toward the right in the drawing is referred to as the Y1 direction, and the direction toward the left in the drawing is referred to as the Y2 direction.
As in the first embodiment, the interior of the main body 11 of the attachment 2 is divided into the first air passage P1 and the second air passage P2. In fig. 14, the first air passage P1 is located on the Y1 side, and the second air passage P2 is located on the Y2 side. Further, the peripheral edge outlet 23 of the second air passage P2 is located at the end on the Y1 side.
As described above, the blower 103 includes the warm air generating unit 51 therein. As shown in fig. 14, the warm air generating unit 51 is disposed on the Y2 side near the inside of the blower 103.
The warm air is blown out substantially perpendicularly from the warm air generation unit 51 toward the blow-out surface of the blow-out port 59. Further, the temperature of the warm air blown out from the warm air generating portion 51 shows a distribution shown by a solid line in fig. 14 along the arrangement position thereof. That is, a temperature peak of the warm air exists in a substantially central portion of the arrangement position of the warm air generating unit 51.
As shown in fig. 14, in the hair care device 101 of the present embodiment, the warm air generator 51 of the blower 103 is disposed so as to correspond to the second air passage P2 of the accessory 2. That is, the warm air generator 51 and the second air passage P2 are disposed closer to the Y2 side.
With the above configuration, the wind having a higher temperature of the wind blown out from the blower 103 can be guided to the second duct P2 side. The air passing through the second air passage P2 changes its direction in the main body 11, and is finally blown out from the peripheral edge blow-out port 23 to a position different from the processing portion. Thus, the wind having a relatively high temperature is blown to a position other than the treatment site. The second air passage P2 is formed to detour inside the main body 11. Therefore, the temperature of the air passing through second air passage P2 tends to decrease to some extent before reaching peripheral edge blowout port 23.
In the hair care device 101 of the present embodiment, the bent plate portion 34 is disposed in the main body portion 11 of the attachment 2 at a position at least partially overlapping the position where the warm air generating portion 51 is disposed when viewed from the front of the outlet port 59 of the blower 103. By providing the curved plate portion 34, the high-temperature wind directly blowing from the warm air generating portion 51 into the interior of the main body portion 11 of the metal fitting 2 is blocked by the curved plate portion 34 and is not blown out from the blowing ports 22a and 22 b. That is, the bent plate portion 34 can provide a wind receiving effect of blocking high-temperature wind directly blown from the warm air generating portion 51 into the main body portion 11 of the metal fitting 2.
With the above configuration, the air having a relatively low temperature (at least air having a lower temperature than the air sent out to the second port P2 side) of the air blown out from the blower 3 can be blown out preferentially from the first port P1 to the air outlets 22a and 22 b. Thereby, the comfort of the user can be improved when using the hair care device 1.
< third embodiment >
Next, a third embodiment of the present invention will be described. In the first and second embodiments described above, the entire warm air generating unit 51 is disposed on the side closer to Y2 in the blower 3 or the blower 103. In contrast, the hair care device 201 according to the third embodiment differs in the configuration of the warm air generating unit 251 of the blower 203.
Fig. 15 shows an internal configuration of a hair care device 201 according to a third embodiment. As shown in fig. 15, the hair dryer 203 constituting the hair care device 201 includes a warm air generating unit 251. The warm air generator 251 includes a heater 253, a fan 254, a motor (not shown), and the like. As shown in fig. 15, the fan 254 is located at the center of the blower 203, and the heater 253 is disposed near the Y2 side. This makes it possible to position the peak temperature of the warm air on the Y2 side.
The same configuration as that of the first embodiment can be applied to the other configurations. The configuration of the warm air generating unit 251 according to the present embodiment may be applied to the blower 103 according to the second embodiment.
As a modification of the present embodiment, the fan 254 may be positioned at the center of the blower 203, the coil winding of the heater 253 may be made dense on the Y2 side and thick on the Y1 side, and the temperature peak of the warm air may be positioned on the Y2 side.
The arrangement of the heater and the fan in the warm air generating unit is not limited to the above configuration. In the above configuration, the fan is located on the downstream side of the heater, but as another configuration, for example, the heater may be disposed on the downstream side of the fan.
< fourth embodiment >
Next, a fourth embodiment of the present invention will be explained. In the first and second embodiments described above, the hair care device in which the attachment 2 is attached to the hair dryer having a long longitudinal direction (substantially cylindrical shape) has been described as an example. However, the attachment (fitting) according to one embodiment of the present invention may be attached to a hair dryer having a different shape from the hair dryer and used.
For example, the attachment (fitting) according to one aspect of the present invention may be attached to the air outlet of a hair dryer having a substantially L-shaped or substantially T-shaped configuration in a side view, and used. More specifically, the attachment according to one embodiment of the present invention may be attached to a hair dryer having a shape as shown in patent document 1 (utility model registration No. 3184955) and used.
Therefore, a hair care device in which the above-described attachment 2 is attached to the air outlet of a hair dryer having a substantially L-shape or a substantially T-shape in a side view is also included in an embodiment of the present invention.
