Description

Technical Field

[0001] The present disclosure relates to a garment with a blower device in which a blower device that blows wind toward, for example, a body or the like by rotating a wing is attached to a garment fabric.

Background Art

[0002] In recent years, there have been many sweltering days that are unpleasant for people throughout the year. On sweltering days, as a measure to prevent heat stroke, frequent small amounts of fluid intake and the use of appropriate cooling devices are encouraged.

[0003] However, due to reasons such as the absence of cooling equipment or insufficient cooling effect, workers working outdoors in sweltering heat, workers working in a stuffy indoor environment, and people enjoying recreation, sports, watching games, etc. under the scorching sun cannot cool off with a cooling device.

[0004] Therefore, in recent years, many clothes and the like with an air-conditioning function have been developed for people seeking to avoid the heat. An example of such an air-conditioned garment is disclosed in Patent Document 1.

[0005] Patent Document 1 is an air-conditioned garment in which a blower device is attached to the fabric of the garment. The blower device includes a propeller that blows out wind and a casing that covers the periphery of the propeller so as to be ventilable. The casing includes an inner case portion located on the leeward side of the propeller. The inner case portion serves as a guard provided with intermittent gaps at a plurality of locations. The side surface of the guard is formed along the rotation axis of the propeller.

[0006] In Patent Document 1, with the casing of the main body inserted through the opening of the fabric of the air-conditioned clothing from the outside of the fabric, and with the flange of the main body abutted against the outer peripheral edge of the opening of the fabric, the pressing member is attached from the inside of the fabric toward the casing of the main body. The blower is attached in a state where the fabric of the air-conditioned clothing is sandwiched between the flange of the main body and the pressing member by fixing the main body and the pressing member. By the rotation of the propeller, the air passes through the gaps between adjacent guards and is blown toward the body inside the fabric. The air sent to the body by the blower attached to the clothing of Patent Document 1 will pass through the clothing and be sent out of the clothing from the collar and cuffs. Incidentally, while the air sent to the body by the blower circulates inside the clothing, the sweat emitted from the wearer's body is evaporated, and the body of the wearer is cooled by the heat of vaporization during evaporation.

Summary of the Invention

Problems to be Solved by the Invention

[0008] In the technology of Patent Document 1, there are the following problems. For example, the air sent out of the clothing from the collar through the inside of the clothing by the blower attached to the clothing is likely to be dispersed, and since the air could not be guided toward the head of the wearer, there was a problem that the body of the wearer could not be effectively cooled.

[0009] The present disclosure has been made to solve the above problems, and an object thereof is to provide a clothing with a blower that can effectively cool the body of the wearer by guiding the air sent by the blower toward the head of the wearer of the clothing with the blower.

Means for Solving the Problems

[0010] In at least one aspect of the present disclosure made to solve the above problems, in a clothing body formed by at least a front body, a back body, and a collar, the main body of the bedding In a clothing with a blower device having a blower device attached to send wind from the outside to the inside of the clothing body, the blower device has a blade that sends wind by rotation, and a guard that covers the periphery of the blade on the lower side of the blown wind and is formed to be ventilable. At least a part of the upper end of the collar is composed of a permissive fabric that allows ventilation, and a wind guiding part is provided to guide the wind sent into the clothing body by the blower device toward the head of the wearer of the clothing with the blower device, and the wind guiding part protrudes from the uppermost end of the collar.

[0011] Note that the clothing according to the present disclosure is a general term for a concept including each concept of (a) upper garments such as jackets, jumpers, suits, vests, etc., (b) undergarments such as pants, trousers, etc., and (c) those worn on the feet and legs such as socks, foot warmers, etc., which are roughly classified into.

[0012] Note that the permissive fabric that allows ventilation according to the present disclosure has a gap through which wind can pass from one side to the other side of the permissive fabric, and is a fabric through which wind can pass from one side to the other side of the permissive fabric. Specifically, as the permissive fabric that allows ventilation, for example, a fabric having a mesh structure in which gaps are formed in the permissive fabric by a weaving method or a knitting method, a fabric in which the permissive fabric is processed to provide through-holes through which wind can pass from one side to the other side of the permissive fabric, etc. can be mentioned. Note that examples of the material of the permissive fabric that allows ventilation include nylon, polyester, etc.

[0013] According to this aspect, with the clothing with a blower, the blower blows air from the outside of the clothing body formed by at least the front body, the back body, and the collar into the inside of the clothing body. Then, the air sent into the inside of the clothing body by the blower is guided from a wind guiding portion disposed at least partially at the upper end of the collar, protruding from the uppermost end of the collar and made of a permissive fabric that allows ventilation, toward the head of the wearer of the clothing with the blower. Thereby, the air sent from the outside of the clothing body into the inside of the clothing body can cool, for example, a part of the body of the wearer inside the clothing body. Further, it is possible to avoid the air sent into the inside of the clothing body from being dispersed from the collar by flowing through the wind guiding portion protruding from the uppermost end of the collar, and the head of the wearer can also be cooled by the air. Therefore, by guiding the air sent by the blower toward the head of the wearer of the clothing with the blower, it is possible to provide clothing with a blower that can effectively cool the body of the wearer.

[0014] In the above aspect, the collar is composed of an outer collar and an inner side provided inside the outer collar. By fixing one end of the permissive fabric to at least a part of the upper end of the outer collar and fixing the other end of the permissive fabric to at least a part of the upper end of the inner collar, it is preferable that a wind guiding path is formed in the wind guiding portion through which the air sent into the inside of the clothing body by the blower flows.

[0015] According to this aspect, the air sent into the inside of the clothing body by the blower is caused to flow through the wind guiding path formed in the wind guiding portion by fixing one end of the permissive fabric to at least a part of the upper end of the outer collar and fixing the other end of the permissive fabric to at least a part of the upper end of the inner collar, and is guided to the head of the wearer. Thereby, without discharging the air sent to the inside of the clothing body to the outside of the clothing body, the air can be made to flow from the inside of the clothing body to the wind guiding portion, guided from the wind guiding portion, and the head of the wearer can be cooled, and the body of the wearer can be cooled more effectively.

[0016] In the above aspect, when no air flows through the air guiding portion by the air blower, the air guiding portion is in a flattened state, while when air flows through the air guiding portion by the air blower, the air guiding portion is in an expanded state, which is preferable.

[0017] According to this aspect, when no air flows through the air guiding path by the air blower, since the air guiding portion is in a flattened state, even if the wearer's body contacts the air guiding portion, it is less likely to give the wearer a sense of discomfort compared to the case where the air guiding portion is in an expanded state. On the other hand, when air flows through the air guiding portion by the air blower, the air guiding portion is in an expanded state, so a large amount of air from the air blower will be guided to the wearer's head. Thereby, depending on whether air flows through the air guiding path by the air blower, the state of the air guiding portion can be changed to improve the usability for the wearer.

[0018] In the above aspect, the outer collar is composed of an outer collar fabric that blocks ventilation, and the inner collar is composed of a first inner collar fabric that blocks ventilation and a second inner collar fabric that allows ventilation. At least a part of the upper end of the first inner collar fabric is fixed to the other end of the allowable fabric, and a collar-side air guiding path for guiding the air sent into the interior of the clothing body by the air blower to the air guiding path is preferably formed between the outer collar and the inner collar.

[0019] Note that the first inner collar fabric that blocks ventilation according to the present disclosure is a fabric in which there is no gap through which air can pass from one side to the other side of the first inner collar fabric, and air cannot pass from one side to the other side of the first inner collar fabric. Examples of the material of the first inner collar fabric that blocks ventilation include nylon, polyester, etc.

[0020] Note that the second inner collar fabric that allows ventilation according to the present disclosure is a fabric having a gap through which air can pass from one side to the other side of the second inner collar fabric, and air can pass from one side to the other side of the second inner collar fabric. Specifically, examples of the second inner collar fabric that allows ventilation include a fabric having a mesh structure in which gaps are formed in the second inner collar fabric by a weaving method or a knitting method, and a fabric in which the second inner collar fabric is processed to provide through-holes through which air can pass from one side to the other side of the second inner collar fabric. Note that examples of the material of the second inner collar fabric that allows ventilation include nylon and polyester.

[0021] According to this aspect, the air sent into the interior of the clothing body by the air blower flows in from the second inner collar fabric and circulates through the collar-side air guiding paths formed in the outer collar and the inner collar, and instead of flowing out of the clothing body from the first inner collar fabric and the outer collar fabric, it flows into the air guiding path. Thereby, it is possible to avoid the air sent into the interior of the clothing body by the air blower from being discharged from the first inner collar fabric and the outer collar fabric to the outside of the clothing body, and the air guided from the air guiding portion can cool the wearer's head.

[0022] In the above aspect, the guard has one or more air direction adjusting members. The air direction adjusting member is connected to a laminar flow introducing portion including a first side surface parallel to the rotation axis of the wing, and an air direction variable portion including a second side surface that bends radially outward around the rotation axis and is connected to the first side surface. In the guard, it is preferable that the air direction adjusting member is adjacent to a gap serving as an air flow path with respect to the radial direction, and the first side surface and the second side surface are arranged at positions in contact with the air flow path.

[0023] According to this aspect, the directivity of the wind blown out from the guard is expanded compared to the blowing device according to the prior art in Patent Document 1 and the like, and the wind from the guard blows out over a wider area in addition to the downstream flow along the direction of the rotation axis. Moreover, the wind sent out from the blades does not stay around the guard, but flows around the blowing device of the present disclosure in a wide blowing area centered on the rotation axis through the gaps of the guard. In addition, since the wind sent out from the blades reaches widely the area around the blowing device of the present disclosure, the wearer of the clothing with the blowing device can receive the wind sent from the blowing device not only in the central area facing the blades but also in the surrounding areas away from the central area of the body.

[0024] In the above aspect, it is preferable that the plurality of wind direction adjusting members are arranged concentrically with the center of the rotation axis and intermittently overlap with respect to the radial direction with the gap therebetween.

[0025] According to this aspect, due to the rotation of the blades, the blown wind forms a flow that includes a flow along the direction of the rotation axis by the wind direction adjusting member and a flow that sufficiently spreads in the radial direction orthogonal to the rotation axis, and diffuses through the gaps of the guard into a wide blowing area. Thereby, the wearer of the clothing with the blowing device can receive the diffused wind.

[0026] In the above aspect, it is preferable that, for the plurality of wind direction adjusting members, the angle of the second side surface relative to the first side surface increases from the inner side in the radial direction to the outer side in the radial direction for each wind direction adjusting member.

[0027] According to this aspect, due to the rotation of the blades, the blown wind forms a flow that includes a flow along the direction of the rotation axis by the wind direction adjusting member and a flow that sufficiently spreads in the radial direction orthogonal to the rotation axis, and diffuses through the gaps of the guard into an even wider blowing area. Thereby, the body of the wearer of the clothing with the blowing device can be exposed to the wind over a wide range.

[0028] In the above aspect, it is preferable that the separation distance between the leeward part of the blade, which is the leeward most part of the blades, and the wind inflow side end face, which is the windward most part of the laminar flow introduction part of the wind direction adjusting member, is at most 10 mm.

[0029] According to this aspect, due to the rotation of the blades, the wind sent to the leeward side by the blades forms a flow along the direction of the rotation axis by the wind direction adjusting member, and also spreads sufficiently in a direction perpendicular to the rotation axis, for example, as an example of the angle formed by the air blowing region STw shown in FIG. 13, in a flow with a spread such as 100 to 160 (deg), and can be blown out in a manner of diffusing from the guard to a wide air blowing region. As a result, the wearer of the garment with the air blowing device can receive more diffused wind.

[0030] In the above aspect, it is preferable that in the wind direction adjusting member, the wind inflow side end face, which is the windward most part of the laminar flow introduction part, and the first side face are connected via an R-shaped curved surface.

[0031] According to this aspect, when the wind trying to flow into the gap hits the first side face, the pressure loss of the air flow is reduced, the generation of vortices is suppressed by the curved surface, and the wind flows toward the second side face.

[0032] In the above aspect, it is preferable that in the wind direction adjusting member, the first side face and the second side face are connected via an R-shaped curved surface.

[0033] According to this aspect, when the wind flowing into the gap flows from the first side face toward the second side face, when it hits the second side face and passes through the gap, the pressure loss of the air flow is reduced, the generation of vortices is suppressed by the curved surface, and the wind can be supplied to the outside.

[0034] In the above aspect, it is preferable to include a drive unit that rotates the blade, and the guard is formed on the outer periphery of the drive unit arranged at the center in the radial direction.

[0035] According to this aspect, since the drive unit is located in a part of the blower device that does not send out the wind generated by the blades, the entire blower device can be made compact, and the space between the clothing and the wearer's body can be effectively utilized.

Advantages of the Invention

[0036] Therefore, according to the blower device of the present disclosure, there is an excellent effect of providing a clothing with a blower device that can effectively cool the wearer's body by guiding the wind sent by the blower device toward the head of the wearer of the clothing with the blower device.

Mode for Carrying Out the Invention

[0038] Hereinafter, the air blower device and the clothing with the air blower device according to the present disclosure will be described in detail with reference to embodiments. The air blower device according to the present disclosure is a fan unit that supplies air, through a guard, toward, for example, the body by the rotation of the blades. The clothing with the air blower device according to the present disclosure is configured by mounting the air blower device according to the present disclosure as a fan unit for sending air on the clothing material, and the air can be blown toward the body by this air blower device. Note that the air blower device according to the present disclosure is referred to as the air blower device 1 in the present embodiment. Further, the clothing with the air blower device according to the present disclosure is referred to as the clothing 100 with the air blower device in the present embodiment.

[0039] First, the configuration of the air blower device 1 will be described. FIG. 1 is a side view showing the air blower device according to the embodiment. FIG. 2 is a plan view of the air blower device shown in FIG. 1 viewed from the intake side, and a plan view of the air blower device viewed from the air blowing side is shown in FIG. 3. FIG. 4 is a perspective view of the air blower device shown in FIG. 1 viewed from the air blowing side. FIG. 5 is a cross-sectional view taken along the line A-A in FIG. 3, with a part shown in a side view. FIG. 6 is an exploded perspective view of the air blower device shown in FIG. 1.

[0040] In the air blower device 1 according to the present embodiment, in FIG. 1, the vertical direction is defined as the axial direction AX along the axis C, in FIG. 2, the direction orthogonal to the axial direction AX is defined as the radial direction RD, and the circumferential direction centered on the axis C along the axial direction AX is defined as the circumferential direction CR. In each of the figures after FIG. 3, the directions defined in FIGS. 1 and 2 are followed. Also, in each figure, illustration of power sources, electrical wiring, connectors, etc. necessary for the air blower device 1 is omitted.

[0041] As shown in FIGS. 1 to 6, the blower 1 includes a case body 2, a blade body 60, a drive unit 70, etc. For example, the blade body 60 corresponds to the blade according to the present disclosure, and for example, the drive unit 70 corresponds to the drive unit according to the present disclosure.

[0042] <Regarding the blade body 60 and the drive unit 70> As shown in FIGS. 5 and 6, the blade body 60 includes a boss portion 62 and blades 61. The blade body 60 is a propeller fan that can rotate about a rotation shaft 71 disposed on the axis C by a drive unit 70 having a rotation shaft 71 and its bearing, an electric motor, etc. The blade body 60 and the drive unit 70 are housed in the case internal space 30S.

[0043] A power connection portion 72 is provided in the blower side case portion 30. The power connection portion 72 is detachably formed with a plug or the like that is electrically connected to a power source, a power supply side connection member (not shown), and the drive unit 70 is energized via the power source by the conduction between the power supply side connection member and the power connection portion 72.

[0044] In this embodiment, nine blades 61 are connected to the boss portion 62. Note that the number of blades 61 connected to the boss portion 62 is not limited to nine, and may be, for example, 5, 7, or an odd number greater than 9. This is because when the blade body is composed of an odd number of blades, the vibration generated during the rotation of the blades is reduced compared to the case where the number of blades is even.

[0045] Also, when the number of blades 61 is, for example, 7, 9, etc., which is more than 5, the twist angle of the blades 61 connected to the boss portion 62 inevitably becomes larger for each blade 61 compared to the case of 5. When the twist angle of the blades 61 becomes larger, the wind is sent out from almost the entire surface area of the blades 61, and the pressure distribution of the wind on the surface of the blades 61 is more likely to be uniform, and the noise during blowing can also be reduced.

[0046] Moreover, when the number of the wings 61 is 7 or 9, the distance between adjacent wings 61 becomes smaller compared to the case where the number is 5. Therefore, for each wing 61, although slightly, it becomes possible to significantly suppress the interruption of the air flow continuously sent out from the wing 61, and the wind becomes a smooth air flow with suppressed intensity variations and is sent out to the person receiving the wind in a so-called gentle tactile state.

[0047] <Regarding the intake side case part 10> The case body 2 is composed of an intake side case part 10 and a blower side case part 30. The intake side case part 10 has an intake side flange 11, an intake side peripheral wall part 12, an intake part 13, etc.

[0048] The intake side flange 11 is formed in an annular shape, and the inner peripheral side of this intake side flange 11 serves as the intake part 13. The intake part 13 has an intake port 14 for taking in the wind AR into the case body 2. In the present embodiment, as shown in FIGS. 1 and 5, the intake part 13 is formed in a shape that gently rises with a height difference M of about 3 mm, for example, from the inner peripheral side of the intake side flange 11 toward the central part passing through the axis C.

[0049] However, it is preferable that the intake part 13 has a height difference M closer to 0 mm. As will be described later, when the blower device 1 is in a state of being worn on clothing, if the intake part has a height difference M of, for example, 10 mm or more, the intake part of the blower device is likely to come into contact with obstacles or the like existing around it. In addition, the wearer of this clothing will be affected in their movements due to the protrusion of the intake part of the blower device. For these reasons, in the intake side case part 10, if the intake part 13 has a flatter shape, it is easier to avoid contact with surrounding obstacles or the like, and it is possible to suppress having an adverse effect on the movements of the wearer of the clothing.

[0050] The intake side peripheral wall part 12 is integral with the intake side flange 11 and stands upright cylindrically from the inner peripheral edge of the diameter of the intake side flange 11. As shown in FIGS. 5 and 6, on the outer peripheral surface 12a of the intake side peripheral wall part 12, protruding pieces 20 are provided in a distributed arrangement at a plurality of locations in the circumferential direction and the axial direction AX.

[0051] <Regarding the blower-side case portion 30> As shown in FIGS. 1 and 3 to 6, the blower-side case portion 30 includes a guard 3, a blower-side flange 31, a blower-side peripheral wall portion 32, a case internal space 30S surrounded by the blower-side peripheral wall portion 32, and the like. The blower-side flange 31 is formed in an annular shape. The blower-side peripheral wall portion 32 is integral with the blower-side flange 31 and stands upright cylindrically from the inner peripheral side of the blower-side flange 31. For example, the guard 3 corresponds to the guard according to the present disclosure.

[0052] The outer peripheral surface 32a of the blower-side peripheral wall portion 32 is a gripping portion 33 formed over the entire circumference in the circumferential direction CR in a manner of alternately repeating concave portions and convex portions. Thus, when a person who wants to attach the blower device 1 to the garment 100 with the blower device rotates the blower-side case portion 30 manually relative to the intake-side case portion 10 about the axis C, the person can firmly grasp the gripping portion 33 with fingers while suppressing slippage. Therefore, the blower-side case portion 30 is easy to rotate with the fingers of the user.

[0053] <Regarding the assembly of the intake-side case portion 10 and the blower-side case portion 30> FIG. 7 is an explanatory view schematically showing in plan view a fixed guide formed in the blower device according to the embodiment. As shown in FIGS. 6 and 7, a plurality of fixed guides 40 are disposed on the inner peripheral surface 32b of the blower-side peripheral wall portion 32. The diameter of the inner peripheral surface 32b of the blower-side peripheral wall portion 32 is larger than the outer diameter of the protruding piece 20 provided on the outer peripheral surface 12a of the intake-side peripheral wall portion 12, and is sized such that the protruding piece 20 and the fixed guide 40 can be engaged with each other.

[0054] As shown in FIG. 7, the fixed guide 40 extends in a manner that connects an end portion 41a and the other end portion 40b in an arc shape along the inner peripheral surface 32b of the air supply side peripheral wall portion 32 when viewed from the axial direction AX, and is formed in a manner inclined at an angle Φ from the horizontal direction when viewed from the radial direction RD. In the fixed guide 40, the end portion 41a and the other end portion 40b have a height difference H in the axial direction AX. The plurality of fixed guides 40 are provided in an intermittent arrangement mode, spaced apart at a predetermined pitch according to the dimensions of the protruding piece 20 with respect to the axial direction AX.

[0055] The fixed guide 40 has a stopper 44 at the other end portion 40b via an introduction surface 41, a first regulating surface 43a, a first holding surface 42a, a second regulating surface 43b, a second holding surface 42b, a third regulating surface 43c, a third holding surface 42c, a fourth regulating surface 43d, a fourth holding surface 42d, a fifth regulating surface 43e, and a fifth holding surface 42e in order from the end portion 41a side with respect to the lead direction Le on the sliding side of the protruding piece 20 formed on the outer peripheral surface 12a of the intake side peripheral wall portion 12.

[0056] The first holding surface 42a, the second holding surface 42b, the third holding surface 42c, the fourth holding surface 42d, and the fifth holding surface 42e are formed in a flat surface shape without unevenness and serve as surfaces for holding the protruding piece 20. The first regulating surface 43a, the second regulating surface 43b, the third regulating surface 43c, the fourth regulating surface 43d, and the fifth regulating surface 43e are formed in a mountain shape protruding from the first holding surface 42a, the second holding surface 42b, the third holding surface 42c, the fourth holding surface 42d, and the fifth holding surface 42e.

[0057] The first regulating surface 43a, the second regulating surface 43b, the third regulating surface 43c, the fourth regulating surface 43d, the fifth regulating surface 43e, and the stopper 44 regulate the movement of the protruding piece 20 arranged on the holding surfaces such as the first holding surface 42a from both sides of the protruding piece 20 with respect to the lead direction Le. In addition, the movement of the protruding piece 20 arranged on the holding surfaces such as the first holding surface 42a is regulated by contacting the adjacent fixed guides 40 with respect to the axial direction AX.

[0058] In the air blower 1, the intake-side peripheral wall portion 12 of the intake-side case portion 10 is inserted into the case internal space 30S of the blower-side case portion 30, and the intake-side case portion 10 and the blower-side case portion 30 rotate relative to each other about the axis C. While the intake-side case portion 10 and the blower-side case portion 30 rotate relative to each other about the axis C, the protruding piece 20 of the intake-side case portion 10 and the fixed guide 40 of the blower-side case portion 30 are positioned by engagement. Thereby, the intake-side case portion 10 and the blower-side case portion 30 are assembled.

[0059] In the air blower 1, among the first holding surface 42a, the second holding surface 42b, the third holding surface 42c, the fourth holding surface 42d, and the fifth holding surface 42e of the fixed guide 40, depending on the position of the holding surface that holds the protruding piece 20, the axial direction AX separation distance between the intake-side flange 11 of the intake-side case portion 10 and the blower-side flange 31 of the blower-side case portion 30 changes.

[0060] FIG. 8 is an explanatory view showing a state in which a protrusion is engaged with a fixed guide in the air blower according to the embodiment, and shows a case of the fixed position A where the flange of the intake-side case portion and the flange of the blower-side case portion are most separated.

[0061] As an example, as shown in FIG. 8, when the protruding piece 20 slid from the introduction surface 41 is positioned by the first holding surface 42a located between the fixed guide 40 and the first regulating surface 43a and the second regulating surface 43b, the intake-side flange 11 and the blower-side flange 31 are in the fixed position A separated by the largest flange distance K1.

[0062] FIG. 9 is an explanatory view showing a state in which a protrusion is engaged with a fixed guide, similar to FIG. 8, and shows a case of the fixed position B where the flange of the intake-side case portion and the flange of the blower-side case portion are closest.

[0063] Also, as shown in FIG. 9, when the protruding piece 20 is positioned by the fifth holding surface 42e located between the fixed guide 40, the fifth regulating surface 43e, and the stopper 44, the intake-side flange 11 and the blower-side flange 31 are at the fixed position B where they are separated by the smallest flange-to-flange distance K5 (K5 < K1).

[0064] FIG. 10 is an explanatory diagram showing a state in which the protrusion is engaged with the fixed guide, similar to FIGS. 8 and 9, and shows the case of the fixed position C where the flange of the intake-side case part and the flange of the blower-side case part are separated at an intermediate position between the fixed position A and the fixed position B.

[0065] Also, as shown in FIG. 10, when the protruding piece 20 is positioned by the third holding surface 42c located between the fixed guide 40, the third regulating surface 43c, and the fourth regulating surface 43d, the intake-side flange 11 and the blower-side flange 31 are at the fixed position C where they are separated by a flange-to-flange distance K3 (K5 < K3 < K1) that is between the flange-to-flange distance K1 and the flange-to-flange distance K5.

[0066] In this way, the blower device 1 can vary the axial separation distance AX between the intake-side flange 11 of the intake-side case part 10 and the blower-side flange 31 of the blower-side case part 30. Therefore, when the blower device 1 is mounted by sandwiching the peripheral edge portion 122 of the clothing material 102 between the intake-side flange 11 and the blower-side flange 31, as in the clothing 100 with a blower device described later, it can accommodate a wide range of thicknesses of the gripped parts such as the peripheral edge portion 122 that can be sandwiched.

[0067] Note that, as shown in FIG. 6, the blower device 1 according to the present embodiment is configured with a structure in which the protruding piece 20 is provided on the outer peripheral surface 12a of the intake-side peripheral wall portion 12 of the intake-side case part 10, and the fixed guide 40 is provided on the inner peripheral surface 32b of the blower-side peripheral wall portion 32.

[0068] However, the blower device may be configured with a structure in which a protruding piece such as the protruding piece 20 is provided on the outer peripheral surface of the blower-side peripheral wall portion, and a fixed guide such as the fixed guide 40 is provided on the outer peripheral surface of the intake-side peripheral wall portion of the intake-side case part.

[0069] Further, the blower device 1 according to the present embodiment has a structure in which the intake side case portion 10 and the blower side case portion 30 are positioned and assembled by the engagement between the protruding piece 20 and the fixed guide 40.

[0070] However, the blower device may be configured with a structure in which the intake side case portion and the blower side case portion are fixed and assembled by, for example, screwing, fitting, screw fastening, etc. between the intake side case portion and the blower side case portion. In this case, the fixing means between the intake side case portion and the blower side case portion is not particularly limited and can be variously changed.

[0071] Further, the blower device 1 according to the present embodiment has a structure in which the intake side peripheral wall portion 12 of the intake side case portion 10 is inserted inside the blower side peripheral wall portion 32 of the blower side case portion 30 to assemble the intake side case portion 10 and the blower side case portion 30.

[0072] However, it is not limited thereto. For example, in the blower device 1, the blower device according to the present disclosure may have a structure in which the blower side peripheral wall portion of the blower side case portion is inserted inside the intake side peripheral wall portion of the intake side case portion so that the inserting member is on the blower side peripheral wall portion 32 side to assemble the intake side case portion and the blower side case portion.

[0073] <Regarding the guard 3> As shown in FIGS. 4 to 6, the guard 3 is formed on the outer periphery of the drive unit 70 disposed at the center in the radial direction RD on the opposite side of the blower side flange 31 with respect to the axial direction AX. The guard 3 has blades 61 that send air by rotation, covers the periphery of the blades 61 etc. on the lower side Fd of the blown air, and is ventable through the gap 4. The guard 3 is formed in a manner of covering the case internal space 30S surrounded by the blower side peripheral wall portion 32 from the inner peripheral side of the blower side peripheral wall portion 32 toward the central portion passing through the axis C. The air sent out from the blades 61 passes through the guard 3 and is supplied to the outside.

[0074] FIG. 11 is a view showing the main part of FIG. 5. FIG. 12 is a sectional view showing an air direction adjusting member formed in the blower device according to the embodiment.

[0075] The guard 3 has one or more wind direction adjusting members 50. In this embodiment, as shown in FIGS. 3 to 12, three wind direction adjusting members 50A, 50B, 50C (50) are formed on the guard 3. For example, the wind direction adjusting member 50 corresponds to the wind direction adjusting member according to the present disclosure.

[0076] All three wind direction adjusting members 50A, 50B, 50C (50) are composed of a laminar flow introducing portion 51 and a wind direction variable portion 56, as shown in FIGS. 11 and 12. The laminar flow introducing portion 51 is a plate-like portion including a first side surface 52 (52A, 52B) arranged parallel to the rotation axis 71 of the blade body 60, that is, along the axial direction AX. For example, the laminar flow introducing portion 51 corresponds to the laminar flow introducing portion according to the present disclosure. For example, the wind direction variable portion 56 corresponds to the wind direction variable portion according to the present disclosure.

[0077] The wind direction variable portion 56 is formed in a manner of being integrally connected to the laminar flow introducing portion 51, as shown in FIGS. 11 and 12. The wind direction variable portion 56 is a plate-like portion including a second side surface 57 (57A, 57B) bent from the first side surface 52 (52A, 52B) in the direction outside the radial direction RD centered on the axis C (right side in the left-right direction in FIG. 11). For example, the first side surface 52 corresponds to the first side surface according to the present disclosure, and for example, the second side surface 57 corresponds to the second side surface according to the present disclosure.

[0078] In the guard 3, all three wind direction adjusting members 50A, 50B, 50C (50) are arranged in an arc shape in the circumferential direction CR around the axis C. The three wind direction adjusting members 50A, 50B, 50C (50) are respectively arranged in a manner of concentrically and intermittently overlapping with respect to the radial direction RD with a gap 4 therebetween.

[0079] That is, as shown in FIGS. 11 and 12, the wind direction adjustment members 50A, 50B, 50C (50) are each in a state adjacent to the gap 4 that forms the wind flow path FL with respect to the radial direction RD. In the wind direction adjustment members 50A, 50B, 50C (50), the first side surface 52 and the second side surface 57 are arranged at positions in contact with the wind flow path FL. For example, the wind flow path FL corresponds to the wind flow path according to the present disclosure, and for example, the gap 4 corresponds to the gap according to the present disclosure.

[0080] Further, in the three wind direction adjustment members 50A, 50B, 50C (50), as shown in FIGS. 11 and 12, the bending angle θ, which is the angle of the second side surface 57 opposite to the first side surface 52, increases from the inner side in the radial direction RD (the left side in the left-right direction in FIG. 11) to the outer side in the radial direction RD (the right side in the left-right direction in FIG. 11) for each wind direction adjustment member 50.

[0081] Specifically, when there are three wind direction adjustment members 50 in the guard 3, as shown in FIGS. 11 and 12, in the first wind direction adjustment member 50A (50) arranged at the position closest to the axis C, the bending angle θ1 (deg) is, for example, 0 ≦ θ1 ≦ 50, and in this embodiment, the bending angle θ1 = 45 (deg).

[0082] Further, in the second wind direction adjustment member 50B (50) adjacent to the first wind direction adjustment member 50A, the bending angle θ2 (deg) is, for example, 0 ≦ θ2 ≦ 70, and in this embodiment, the bending angle θ2 = 60 (deg). Also, in the third wind direction adjustment member 50C (50) arranged at the position farthest from the axis C, the bending angle θ3 (deg) is, for example, 0 ≦ θ3 ≦ 90, and in this embodiment, the bending angle θ3 = 75 (deg).

[0083] Note that the set bending angles θ1 = 45 (deg), θ2 = 60 (deg), and θ3 = 75 (deg) of the three wind direction adjustment members 50A, 50B, 50C (50) are not limited and can be changed as appropriate.

[0084] Here, let the quantity of the wind direction adjustment members 50 be n (0 < n). When there are multiple wind direction adjustment members 50, as shown in FIGS. 11 and 12, the wind direction adjustment member 50 arranged at the position closest to the axis C is set as x = 1, which means the first wind direction adjustment member 50. Also, the wind direction adjustment member 50 arranged at the position farthest from the axis C is set as x = n, which means the nth wind direction adjustment member 50. Let the magnitude of the bending angle θ (deg) of the wind direction adjustment member 50 be y (0 ≤ y ≤ 90), and y is a linear function of the variable x. Note that a (0 < a) is a coefficient, and b (0 ≤ b ≤ 90) is a constant representing an angle (deg).

[0085] Based on such a premise, the bending angle θ of the wind direction adjustment member 50 is set by the following formula (1). y = a * x + b … Formula (1)

[0086] That is, regardless of the quantity of the wind direction adjustment members 50 arranged on the guard 3, in the wind direction adjustment member 50, as long as the bending angle θ of the second side surface 57 formed relative to the first side surface 52 satisfies the condition of 0 ≤ θ ≤ 90 (deg) as shown in Formula (1), and the second side surface 57 bends and connects relative to the first side surface 52 corresponding to the direction in which the wind blown from the wing 61 flows.

[0087] Also, in the wind direction adjustment member, a rotation mechanism may be provided between the laminar flow introduction part and the wind direction variable part, and the wind direction variable part rotates relative to the laminar flow introduction part, so that the magnitude of the bending angle θ of the second side surface formed with the first side surface can be configured to be variably adjustable freely.

[0088] In all of the three wind direction adjustment members 50A, 50B, 50C (50), as shown in FIGS. 11 and 12, among the laminar flow introduction parts 51, the wind inflow side end surface 53 located on the most upwind side and the first side surface 52 (52A, 52B) are connected via an R-shaped inflow side curved surface 54. For example, the wind inflow side end surface 53 corresponds to the wind inflow side end surface according to the present disclosure, and for example, the inflow side curved surface 54 corresponds to the curved surface according to the present disclosure.

[0089] The radius of curvature of the inflow-side curved surface 54 is, as shown in Fig. 12, in a ratio to the distance (thickness) between the opposing first side surfaces 52A and 52B, and is, as an example, of a size corresponding to 10 to 50%. In the present embodiment, the radius of curvature of the inflow-side curved surface 54 is approximately 30% with respect to the thickness between the first side surface 52A and the first side surface 52B.

[0090] Note that the space between the air-inflow-side end face 53 and the first side surface 52A and the space between the air-inflow-side end face 53 and the first side surface 52B may be connected by chamfered C surfaces.

[0091] Furthermore, in all three air-direction adjustment members 50A, 50B, 50C (50), the first side surface 52A (52) and the second side surface 57A (57), both of which are located on the outer side in the radial direction RD (the right side in the left-right direction in Fig. 12), are connected via an R-shaped bending-side curved surface 58.

[0092] The radius of curvature of the bending-side curved surface 58 is, as shown in Fig. 12, in a ratio to the distance (thickness) between the opposing second side surfaces 57A and 57, and is, as an example, of a size corresponding to 50 to 90%. In the present embodiment, the radius of curvature of the bending-side curved surface 58 is approximately 80% with respect to the thickness between the second side surface 57A and the second side surface 57B.

[0093] Note that the first side surface 52A and the second side surface 57A may be connected by a flat surface between the two.

[0094] <Arrangement relationship between the air-direction adjustment member 50 and the blade 61> In the blower device 1, as shown in Fig. 11, the three air-direction adjustment members 50A, 50B, 50C (50) are arranged on the leeward side Fd of the blades 61 of the blade body 60. With respect to the axial direction AX, the separation distance between the blade leeward part 61X, which is the most leeward part Fd of the blades 61, and the air-inflow-side end face 53, which is the most windward part Fw of the laminar flow introduction part 51 of the air-direction adjustment member 50, is at most 10 mm or less. For example, the blade leeward part 61X corresponds to the blade leeward part according to the present disclosure.

[0095] Specifically, in the case of the first wind direction adjustment member 50A (50) disposed at the position closest to the axis C among the three wind direction adjustment members 50A, 50B, 50C (50), the separation distance Da between the wing leeward part 61X and the air inflow side end face 53 is approximately 7 mm. Further, in the case of the third wind direction adjustment member 50C (50) disposed at the position farthest from the axis C, the separation distance Dc between the wing leeward part 61X and the air inflow side end face 53 is approximately 2 mm.

[0096] <Regarding the verification experiment> The applicant of the present application conducted an experiment to investigate the influence on the air flow blown from the wing 61 due to the difference in the separation distance between the wind direction adjustment member 50 and the wing 61. In the experiment, the blower 1 according to the example and the blower 1X according to the comparative example were used, and it was confirmed how different the state of the air flow blown through the guard 3 was between the case of the example and the case of the comparative example, compared with the wing 61.

[0097] The subject was at a position about several centimeters away from the guard 3 for both the blower 1 and the blower 1X, and based on the sensory evaluation received by his / her own body for the behavior of the wind AR blown out through the gap 4 of the guard 3, the difference in the state of the air flow was confirmed and compared between the case of the blower 1 according to the example and the case of the blower 1X according to the comparative example. FIG. 13 is a schematic diagram showing the air flow through the guard by the blowing of the blower according to the example, and FIG. 14 shows a schematic diagram showing the air flow through the guard by the blowing of the blower according to the comparative example.

[0098] As shown in FIG. 13, in the blower 1 according to the example, with respect to the axial direction AX, the separation distance D1c between the point X and the point P is the above-mentioned separation distance Dc = approximately 2 mm. The point X is an arbitrary point located on the horizontal line passing through the wing leeward part 61X of the wing 61 with respect to the radial direction RD. The point P is an arbitrary point located on the horizontal line passing through the air inflow side end face 53 of the third wind direction adjustment member 50C with respect to the radial direction RD.

[0099] On the other hand, in the blower 1X according to the comparative example, with respect to the axial direction AX, the separation distance D2c between point X and point Q exceeds 10 mm. Point X is an arbitrary point located on the horizontal line passing through the downstream part 61X of the blade 61 with respect to the radial direction RD. Point Q is an arbitrary point located on the horizontal line passing through the air inflow side end face 53 of the third air direction adjusting member 50C with respect to the radial direction RD.

[0100] (Experimental results) The experimental results are shown in FIGS. 13 and 14. In the case of the blower 1 according to the embodiment, as shown in FIG. 13, the air AR sent out from the blade 61 passed through the gap 4 and, by the air direction adjusting member 50, had a flow along the axial direction AX and a flow that sufficiently spread in the radial direction RD, and blew out in a mode of diffusing from the guard 3 to the wide air blowing region STw. The angle formed by the air blowing region STw was, for example, approximately 100 to 150 (deg).

[0101] In the case of the blower 1X according to the comparative example, as shown in FIG. 14, the air AR sent out from the blade 61 passed through the gap 4 and, by the air direction adjusting member 50, had a flow directed toward the axial direction AX and a flow that did not sufficiently spread in the radial direction RD, and blew out in a mode of the air blowing region STn that hardly diffused from the guard 3 as compared with the case of the embodiment. The angle formed by the air blowing region STn was, for example, about 40 to 60 (deg).

[0102] (Discussion) As shown in FIGS. 13 and 14, in both the blower 1 according to the embodiment and the blower 1X according to the comparative example, due to the rotation of the blade 61 in the rotation direction RT, the air AR is sent out to the downstream side Fd and blows out toward the body through the gap 4 of the guard 3.

[0103] As shown in FIG. 13, in the blower 1 according to the embodiment, the separation distance D1c between point X and point P is about 2 mm, which is equal to or less than 10 mm, which is a standard for being able to maintain the laminar flow state F1 well. As a result, the air AR sent out from the blade 61 easily flows into the gap 4 while maintaining the laminar flow state F1 well from point X to point P.

[0104] When the wind AR flows substantially in a laminar state F1 to the leeward side Fd and enters the gap 4 of the guard 3, the wind AR flows straight along the first side surface 52 of the laminar flow introduction part 51 in the wind direction adjustment member 50 and flows toward the wind direction variable part 56 in a state of a straight airflow. When the wind AR in the state of a straight airflow reaches the wind direction variable part 56, it hits the second side surface 57 bent radially outward (the side away from the axis C in FIG. 13), and the direction of the wind AR changes along the direction along the second side surface 57.

[0105] In addition, in the three wind direction adjustment members 50A, 50B, 50C (50), the bending angle θ of each wind direction adjustment member 50 is larger in the second wind direction adjustment member 50B than in the first wind direction adjustment member 50A, and larger in the third wind direction adjustment member 50C than in the second wind direction adjustment member 50B, respectively.

[0106] Therefore, when the wind AR in the state of a straight airflow reaches the respective wind direction variable parts 56 in the three wind direction adjustment members 50A, 50B, 50C (50), in the first wind direction adjustment member 50A, the wind AR hits the second side surface 57 bent at a bending angle θ1 = 45 (deg) radially outward (the side away from the axis C in FIG. 13), and becomes a flow along the second side surface 57, and the direction of the wind AR changes.

[0107] Similarly, in the second wind direction adjustment member 50B, it hits the second side surface 57 bent at a bending angle θ2 = 60 (deg) radially outward, and becomes a flow along the second side surface 57, and the direction of the wind AR changes more greatly compared with the case of the first wind direction adjustment member 50A.

[0108] Likewise, in the third wind direction adjustment member 50C, it hits the second side surface 57 bent at a bending angle θ3 = 75 (deg) radially outward, and becomes a flow along the second side surface 57, and the direction of the wind AR changes more greatly compared with the case of the second wind direction adjustment member 50B.

[0109] Therefore, in the blower device 1 according to the embodiment, as shown in FIG. 13, the wind AR passes through the gap 4 and, by the wind direction adjustment member 50, has a flow along the axial direction AX and spreads sufficiently in the radial direction RD, and is considered to be blown out in a manner of diffusing from the guard 3 to the wide blowing area STw.

[0110] On the other hand, as shown in FIG. 14, in the blower device 1X according to the comparative example, the separation distance D2c between the point X and the point Q exceeds 10 mm, which is a standard for generally maintaining the laminar flow state F1 well. In the case of the comparative example, when the wind AR is sent out from the blade 61, it is presumed that the laminar flow state F1 is generally maintained between the point X and the point Q up to the point P in front of the point Q.

[0111] However, when the wind AR sent out from the blade 61 exceeds the point P, which is a standard point for generally maintaining the laminar flow state F1 well, turbulence is likely to occur in the air flow of the wind AR between the point P and the point Q. Therefore, the air flow of the wind AR cannot maintain the laminar flow state F1, and for example, becomes an air flow with vortices or the like, and it becomes difficult for the wind AR to flow straight downward Fd toward the three wind direction adjustment members 50A, 50B, 50C (50).

[0112] That is, as a main factor causing turbulence in the air flow, due to the rotation of the blade body 60, while the wind AR is being blown, strictly speaking, the air flow is intermittently sent from each blade 61 one by one to the downstream side Fd. At this time, for the air flows sent from adjacent blades 61 with a time difference from each blade 61, the flow directions of the respective air flows become greatly different from each other when they reach a position beyond the point P.

[0113] Therefore, due to the confluence of the previously sent air current and the subsequently sent air current, vortices are generated in the flow of the wind AR. This is because the air current of the wind AR is disturbed by the generation of vortices and cannot maintain the laminar flow state F1 well. Also, when the wind AR sent from the wing 61 gradually moves away from the wing 61 beyond the point P, it is more likely to be affected by external disturbances caused by the state of the atmosphere, such as the outside air around the rotating wing body 60, and it becomes difficult to maintain the laminar flow state F1.

[0114] Even if the wind AR is blown from the wing 61 in the laminar flow state F1, when it reaches the three wind direction adjustment members 50A, 50B, 50C (50) and flows into the gap 4 between the guards 3, the wind AR is already in a turbulent air current state with vortices and the like, that is, the turbulent flow state F2.

[0115] When the wind AR in the turbulent flow state F2 flows into the gap 4 and passes through the laminar flow introduction part 51 to the wind direction variable part 56 in the wind direction adjustment member 50, even if the wind AR hits the second side surface 57 bent radially outward (the side far from the axis C in FIG. 14), it is difficult to form a flow along the second side surface 57. Therefore, in the wind direction adjustment member 50, compared with the case of the embodiment, it is difficult for the direction of the wind AR to change along the second side surface 57.

[0116] Therefore, in the air blower 1X according to the comparative example, the wind AR passes through the gap 4 and is in a flow directed in the axial direction AX by the wind direction adjustment member 50 and a flow that does not sufficiently spread in the radial direction RD. Compared with the case of the embodiment, it is considered that the wind AR is blown out in a mode of the air blowing region STn that cannot be sufficiently diffused from the guard 3.

[0117] <Regarding the outline of the clothing 100 with an air blower> Next, the outline of the garment 100 with a blower will be briefly described with reference to FIGS. 15 to 23. FIG. 15 is a front view of the outer surface of the garment with a blower according to the embodiment, as seen from the front body side. FIG. 16 is a rear view of the garment with a blower when the blower is not attached, as seen from the back body side. FIG. 17 is a rear view of the garment with a blower when the blower is attached, as seen from the back body side. FIG. 18 is a front view of the inner side of the garment with a blower when the blower is attached, as seen from the front body side. FIG. 19 is an enlarged front view of the main part of the collar of the garment with a blower shown in FIG. 18. FIG. 20 is a cross-sectional view taken along the line C-C in FIG. 19.

[0118] In the garment 100 with a blower shown in FIG. 15, in FIG. 15, the left - right direction is defined as the Y-axis direction, and the up - down direction is defined as the X-axis direction. In FIGS. 16 to 19 as well, the directions are in accordance with those defined in FIG. 15. Also, in the garment 100 with a blower shown in FIG. 20, in FIG. 20, the left - right direction is defined as the Z-axis direction, and the up - down direction is defined as the X-axis direction. In FIGS. 24 and 25 as well, the directions are in accordance with those defined in FIG. 20.

[0119] As shown in FIGS. 15 to 18, the garment 100 with a blower is formed by attaching the blower 1 according to the present embodiment, which is a fan unit for sending air, to the fabric 102 that forms the vest mentioned as an example. The garment 100 with a blower is configured such that the blower 1 can blow the air AR toward the body BS of the wearer HM.

[0120] The garment 100 with a blower is used, for example, by workers working outdoors in sweltering heat, workers wearing work clothes and working in a steamy indoor environment, people engaged in recreation, sports, watching games, etc. under the scorching sun, especially those who require cold air.

[0121] As shown in FIGS. 15 to 18, the garment 100 with a blower includes a garment body 101, a blower 1, a blower operation unit 200, etc. The blower operation unit 200 has one as an example in the present embodiment. In each figure, the electrical wiring for the blower 1 and the illustration of the power source are omitted.

[0122] <Regarding the clothing body 101> Next, the clothing body 101 will be described with reference to FIGS. 15 to 23. As shown in FIGS. 15 to 18, the clothing body 101 includes a front body 103, a back body 104, a collar 105, a crotch air guiding portion 108 disposed at a part of the upper end of the collar 105, a sleeve hole portion 111 through which the wearer's arm passes when worn, a hem portion 116, and the like. The clothing body 101 is formed in the form of a vest (work clothing without cuffs). However, this clothing with a blowing device may also be work clothing with long sleeves or short sleeves. The collar 105 forms a neckline at the upper part where the wearer's neck is located when worn. The sleeve hole portion 111 has a left cuff portion 111A through which the wearer's left arm passes when worn and a right cuff portion 111B through which the wearer's right arm passes when worn. For example, the front body 103 corresponds to the front body according to the present disclosure, for example, the back body 104 corresponds to the back body according to the present disclosure, for example, the collar 105 corresponds to the collar according to the present disclosure, and for example, the clothing body 101 corresponds to the clothing body according to the present disclosure.

[0123] In the clothing body 101, the fabric 102 is formed in a vest shape by a front side fabric 102A and a back side fabric 102B. Both the front side fabric 102A and the back side fabric 102B are made of synthetic resin fibers excellent in heat resistance, strength, and transpiration, such as nylon and polyester. However, it is not limited to this, and both the front side fabric 102A and the back side fabric 102B may be made of leather.

[0124] As shown in FIG. 15, a storage part 112, which is a pocket for example, is provided in the front body part 103 of the clothing body 101. The storage part 112 includes a first storage part 112A which is a storage part installed on the left chest of the clothing body 101, and a second storage part 112B which is a storage part installed on the right chest of the clothing body 101. Further, the storage part 112 includes a third storage part 112C which is a storage part installed on the left side abdomen of the clothing body 101, and a fourth storage part 112D which is a storage part installed on the right side abdomen of the clothing body 101. An internal space is formed between the front side fabric 102A and the fabric for the storage part sewn to the back side fabric 102B in the first storage part 112A, the second storage part 112B, the third storage part 112C, and the fourth storage part 112D. Thereby, for example, the electrical wiring for the blower device 1 and the power source are taken in and out from the storage part 112.

[0125] The sleeve cuffs 111 (111A, 111B) according to the present embodiment are provided with an annular member having elasticity such as rubber, and it is difficult for air to be released from the sleeve cuffs 111 (111A, 111B). Thereby, it is possible to prevent the air sent into the clothing body 101 by the blower device 1 from being released from the sleeve cuffs 111 (111A, 111B), and a large amount of that air can be released from the collar 105. However, it is not limited to this. For example, a configuration in which air is easily released from the sleeve cuffs 111 (111A, 111B) may be used.

[0126] When the fastener 113 provided on the front body part 103 is opened, the blower-equipped clothing 100 is configured such that, as shown in FIG. 18, the entire back side of the back body part 104 of the clothing body 101 can be confirmed when viewed from the front body part 103 side.

[0127] As shown in FIGS. 16 to 18, the attachment parts 120 to which the blower device 1 can be attached are provided one by one at the left part of the waist WS and the right part of the waist WS in the back body part 104 of the blower-equipped clothing 100. However, it is not limited to this. For example, the attachment parts 120 may be provided at two locations on the abdomen of the front body part 103. Further, for example, the attachment parts 120 may be provided at two locations on the back in the back body part 104 of the blower-equipped clothing 100.

[0128] As shown in FIGS. 15, 16, and 18, the attachment portion 120 has an insertion hole 121 for the attachment portion formed in the attachment portion 120 and a peripheral edge portion 122 around the insertion hole 121 for the attachment portion. Note that the attachment portion 120 is sewn from above the back fabric 102B. The insertion hole 121 for the attachment portion is a hole for detachably attaching the blower device 1. The attachment portion 120 is made of a material with higher rigidity (for example, leather) than the back fabric 102B and is composed of a fabric that does not allow air to pass through. Note that the attachment portion 120 may be composed of a fabric such as rubber or resin.

[0129] As shown in FIGS. 16 to 18, two cold insulation material storage portions 114 for storing a cold insulation agent are sewn to the back fabric 102B of the back body 104 of the garment 100 with a blower device. The cold insulation material storage portion 114 is composed of a fabric having a mesh structure with gaps formed by a weaving or knitting method of synthetic resin fibers excellent in heat resistance, strength resistance, and evaporation property, such as nylon or polyester. An internal space is formed between the fabric of the cold insulation material storage portion 114 and the back fabric 102B. Thereby, the cold insulation material is taken in and out from the cold insulation material storage portion 114. Note that a hook-and-loop fastener 115 is sewn to the upper end of the cold insulation material storage portion 114. By engaging the hook-and-loop fastener 115 with the hook-and-loop fastener sewn to the back fabric 102B, it is possible to prevent the cold insulation material stored in the cold insulation material storage portion 114 from popping out.

[0130] As shown in FIGS. 16 to 18, in the cold insulation material storage part 114, there are a first cold insulation material storage part 114A installed at the back center part BC of the back body 104 of the clothing 100 with a blower, and a second cold insulation material storage part 114B installed at the waist part WS of the back body 104 of the clothing 100 with a blower. By storing a cold insulation agent in the first cold insulation material storage part 114A, the back center part BC of the wearer HM can be cooled, and the air sent to the inside of the clothing main body 101 by the blower 1 can also be cooled. Also, by storing a cold insulation agent in the second cold insulation material storage part 114B, the waist part WS of the wearer HM can be cooled, and the air sent to the inside of the clothing main body 101 by the blower 1 can also be cooled.

[0131] As shown in FIG. 18, at the hem opening part 116 of the clothing 100 with a blower according to the present embodiment, two hem adjusting members 117 for making it possible to adjust the length around the hem are provided. Note that the hem adjusting member 117 is an annular member having elasticity such as rubber. By adjusting the length around the hem by the hem adjusting member 117, it is possible to make it difficult for air to be released from the hem opening part 116. Thereby, it is possible to prevent the air sent to the inside of the clothing main body 101 by the blower 1 from being released from the hem opening part 116, and a large amount of that air can be released from the collar 105. However, it is not limited to this. For example, a configuration in which air is easily released from the hem opening part 116 may be used.

[0132] <Regarding the collar 105> Next, the collar 105 will be described with reference to FIGS. 15 to 20. As shown in FIGS. 15 to 19, the collar 105 is composed of an outer collar 106 and an inner collar 107 disposed inside the outer collar 106, that is, on one side in the Y-axis direction (the left side in FIG. 29). The outer collar 106 is composed of an outer collar fabric 106A that blocks ventilation. Specifically, there is no gap through which air can pass from one side to the other side of the outer collar fabric 106A, and it is a fabric through which air cannot pass from one side to the other side. The outer collar fabric 106A according to the present embodiment is composed of, for example, synthetic resin fibers such as nylon and polyester, which are excellent in heat resistance, strength, and flexibility. For example, the outer collar 106 corresponds to the outer collar according to the present disclosure, and for example, the inner collar 107 corresponds to the inner collar according to the present disclosure. For example, the outer collar fabric 106A corresponds to the outer collar fabric according to the present disclosure.

[0133] The inner collar 107 is composed of a first inner collar fabric 107A that blocks ventilation and a second inner collar fabric 107B that allows ventilation. Specifically, there is no gap through which air can pass from one side to the other side of the first inner collar fabric 107A, and it is a fabric through which air cannot pass from one side to the other side. The first inner collar fabric 107A is composed of, for example, synthetic resin fibers such as nylon and polyester, which are excellent in heat resistance, strength, and flexibility. For example, the first inner collar fabric 107A corresponds to the first inner collar fabric according to the present disclosure, and for example, the second inner collar fabric 107B corresponds to the second inner collar fabric according to the present disclosure.

[0134] On the other hand, specifically, the second inner collar fabric 107B has a gap through which air can pass from one side to the other side, and it is a fabric through which air can pass from one side to the other side. The second inner collar fabric 107B is composed of, for example, a mesh structure formed by a weaving or knitting method of synthetic resin fibers such as nylon and polyester, which are excellent in heat resistance, strength, transpiration, and flexibility, to form gaps.

[0135] At the upper end of the crotch 105, as shown in FIGS. 15 to 20, a crotch air guiding portion 108 is provided for guiding the air sent into the interior of the clothing body 101 by the air blower 1 toward the head HD of the wearer HM of the clothing 100 with an air blower. The crotch air guiding portion 108 is composed of a permissive fabric 108A that allows ventilation. Specifically, the permissive fabric 108A is a fabric having a gap through which air can pass from one side to the other side of the permissive fabric 108A. The permissive fabric 108A is formed of a mesh structure having gaps by a weaving or knitting method of synthetic resin fibers excellent in heat resistance, strength, transpiration property, and flexibility, such as nylon, polyester, etc. For example, the crotch air guiding portion 108 corresponds to the air guiding portion according to the present disclosure. For example, the permissive fabric 108A corresponds to the permissive fabric according to the present disclosure.

[0136] As shown in FIGS. 15 to 20, the crotch air guiding part 108 has the allowable fabric 108A folded to the outer front flap 106 and the inner front flap 107 side, that is, one side in the X-axis direction (the lower side in FIG. 20), and one end 108Aa of the allowable fabric 108A is sewn and fixed to the central part IC at the upper end 106Aa of the outer front flap fabric 106A. Further, as shown in FIGS. 15 to 20, the crotch air guiding part 108 has the allowable fabric 108A folded to the outer front flap 106 and the inner front flap 107 side, that is, one side in the X-axis direction (the lower side in FIG. 20), and the other end 108Ab of the allowable fabric 108A is sewn and fixed to the central part OC at the upper end 107Aa of the first inner front flap fabric 107A. As shown in FIG. 20, when the crotch air guiding part 108 has the allowable fabric 108A folded to the outer front flap 106 and the inner front flap 107 side and sewn and fixed to the front flap 105, it protrudes from the uppermost end 106Am of the outer front flap fabric 106A and the uppermost end 107Am of the first inner front flap fabric 107A. Specifically, as shown in FIGS. 15 to 19, when the garment 100 with a blower is viewed from the front side and the back side, the crotch air guiding part 108 has a semi-circular shape protruding to one side in the X-axis direction (the upper side in FIG. 15) from the uppermost end 106Am of the outer front flap fabric 106A and the uppermost end 107Am of the first inner front flap fabric 107A. Also, when the person wears the garment 100 with a blower, the crotch air guiding part 108 protrudes from the uppermost end 106Am of the outer front flap fabric 106A and the uppermost end 107Am of the first inner front flap fabric 107A toward the head HD of the person. The crotch air guiding part 108 has a function of assisting in guiding the air sent to the inside of the garment body 101 by the blower 1 to the head HD of the wearer HM.

[0137] As shown in FIG. 20, the lower end 107Ab of the first inner front flap fabric 107A and the upper end 107Ba of the second inner front flap fabric 107B are sewn and fixed. Also, the lower end 107Bb of the second inner front flap fabric 107B and the lower end 106Ab of the outer front flap fabric 106A are sewn and fixed to the upper end 102u of the clothing fabric 102.

[0138] As shown in FIG. 20, the allowable fabric 108A is folded toward the outer collar 106 and the inner collar 107 side, and one end 108Aa of the allowable fabric 108A is sewn and fixed to the upper end 106Aa of the outer collar fabric 106A, and the other end 108Ab of the allowable fabric 108A is sewn and fixed to the upper end 107Aa of the first inner collar fabric 107A, so that a crotch-side air guide path 109 is formed in the crotch air guide portion 108. This crotch-side air guide path 109 is a flow path for circulating the air sent into the interior of the clothing body 101 by the air blower 1 and guiding the air passing through the allowable fabric 108A to the head HD of the wearer HM. For example, the crotch-side air guide path 109 corresponds to the air guide path according to the present disclosure.

[0139] As shown in FIG. 20, the allowable fabric 108A is folded toward the outer collar 106 and the inner collar 107 side, and one end 108Aa of the allowable fabric 108A is sewn and fixed to the upper end 106Aa of the outer collar fabric 106A, and the other end 108Ab of the allowable fabric 108A is sewn and fixed to the upper end 107Aa of the first inner collar fabric 107A, so that a collar-side air guide path 110 is formed between the outer collar 106 and the inner collar 107. This collar-side air guide path 110 is a flow path for ventilating the second inner collar fabric 107B and guiding the air flowing into the space between the outer collar 106 and the inner collar 107 to the crotch-side air guide path 109 for circulation. For example, the collar-side air guide path 110 corresponds to the collar-side air guide path according to the present disclosure.

[0140] <Regarding the mounting of the air blower 1> Next, with reference to FIGS. 21 to 23, the mounting of the air blower 1 to the clothing 100 with an air blower will be described. FIG. 21 is a schematic side view showing how to mount the air blower according to the embodiment to the fabric of the clothing with an air blower. FIG. 22 is a schematic perspective view showing how to mount the air blower according to the embodiment to the fabric of the clothing with an air blower. FIG. 23 is a cross-sectional view taken along the line B-B in FIG. 17, and is a schematic view showing the flow of the air blown out through the guard in the space between the clothing and the body.

[0141] In the garment 100 with a blower device, when attaching the blower device 1 to the garment body 102, as shown in FIGS. 21 to 22, the intake-side peripheral wall portion 12 is inserted from the outside of the attachment portion 120 into the garment insertion hole 102h formed by perforating the garment body 102 and the attachment portion insertion hole 121 formed by perforating the attachment portion 120. With the intake-side flange 11 of the intake-side case portion 10 in contact with the peripheral edge portion 122 formed with increased rigidity around the outer periphery of the garment insertion hole 102h and the outer periphery of the attachment portion insertion hole 121, the blower-side case portion 30 is disposed between the body BS of the wearer HM and the inside of the garment body 102 with the blower-side flange 31 facing the inside of the garment body 102.

[0142] The intake-side peripheral wall portion 12 of the intake-side case portion 10 passing through the garment insertion hole 102h and the attachment portion insertion hole 121 is between the body BS of the wearer HM and the inside of the garment body 102. This intake-side peripheral wall portion 12 is inserted inside the blower-side peripheral wall portion 32 of the blower-side case portion 30. Then, by relatively rotating the intake-side case portion 10 and the blower-side case portion 30 around the axis C, the protrusion piece 20 of the intake-side case portion 10 and the fixed guide 40 of the blower-side case portion 30 are engaged, and the intake-side case portion 10 and the blower-side case portion 30 are assembled.

[0143] Thus, as shown in FIG. 23, the garment body 102 and the attachment portion 120 are sandwiched between the intake-side flange 11 of the intake-side case portion 10 and the blower-side flange 31 of the blower-side case portion 30, and the blower device 1 is attached to the garment body 101 of the garment 100 with a blower device.

[0144] <Regarding the crotch air guiding portion 108 and the collar-side air guiding path 110> Next, the crotch air guiding portion 108 will be described with reference to FIGS. 24 to 25. FIG. 24 is an explanatory diagram for explaining a state in which the air from the blower device does not flow through the crotch-side air guiding path and the collar-side air guiding portion. FIG. 25 is an explanatory diagram for explaining a state in which the air from the blower device flows through the crotch-side air guiding path and the collar-side air guiding portion.

[0145] First, with reference to FIG. 24, a state in which the air sent into the garment body 101 by the blower device 1 does not flow through the crotch-side air guiding path 109 and the collar-side air guiding path 110 will be described.

[0146] As shown in FIG. 24, when the air sent into the interior of the clothing body 101 by the blower device 1 does not flow through the collar-side air guide path 110, the outer collar 106 does not bulge outward by the air, that is, to one side in the Y-axis direction (the right side in FIG. 24). At the same time, as shown in FIG. 24, when the air sent into the interior of the clothing body 101 by the blower device 1 does not flow through the collar-side air guide path 110, the inner collar 107 does not bulge toward the outside of the inner collar 107, that is, to one side in the Y-axis direction (the left side in FIG. 24). As shown in FIG. 24, since the outer collar 106 and the inner collar 107 do not bulge, it is possible to prevent the outer collar 106 and the inner collar 107 from contacting the wearer HM's neck of the clothing 100 with a blower device, making it difficult for the wearer HM to feel uncomfortable.

[0147] As shown in FIG. 24, when the air sent into the interior of the clothing body 101 by the blower device 1 does not flow through the crotch-side air guide path 109, the crotch air guide portion 108 is not in a state of expanding outward by the air, that is, to both sides in the Y-axis direction (the left and right sides in FIG. 24). That is, as shown in FIGS. 15 to 21 and FIG. 24, the crotch air guide portion 108 is in a flattened state when the air sent into the interior of the clothing body 101 by the blower device 1 does not flow through the collar-side air guide path 110. By the crotch air guide portion 108 disposed at the upper end of the collar 105 being in a flattened state, it is possible to avoid contacting the body of the wearer HM of the clothing 100 with a blower device and making the wearer feel uncomfortable.

[0148] Next, with reference to FIG. 25, the state in which the air sent into the interior of the clothing body 101 by the blower device 1 flows through the crotch-side air guide path 109 and the collar-side air guide path 110 will be described.

[0149] As shown in Fig. 25, when the air sent into the interior of the clothing body 101 by the blower device 1 flows through the collar-side air guide path 110, the outer collar 106 bulges outward by the air, that is, to one side in the Y-axis direction (the right side in Fig. 24). At the same time, as shown in Fig. 25, when the air sent into the interior of the clothing body 101 by the blower device 1 flows through the collar-side air guide path 110, the inner collar 107 bulges toward the outside of the inner collar 107, that is, to one side in the Y-axis direction (the left side in Fig. 24) by the air. As a result, as shown in Fig. 25, the collar-side air guide path 110 formed between the outer collar 106 and the inner collar 107 expands more than the collar-side air guide path 110 shown in Fig. 24. Therefore, a large amount of air flowing through the collar-side air guide path 110 shown in Fig. 25 can be guided to the crotch-side air guide path 109.

[0150] As shown in Fig. 25, when the air sent into the interior of the clothing body 101 by the blower device 1 flows through the crotch-side air guide path 109, the crotch air guide part 108 expands outward by the air, that is, in a manner of expanding toward both sides in the Y-axis direction (the left and right sides in Fig. 24). As a result, the crotch-side air guide path 109 formed in the crotch air guide part 108 expands more than the crotch-side air guide path 109 shown in Fig. 24. Therefore, a large amount of air flowing through the crotch-side air guide path 109 shown in Fig. 25 can pass through the allowable fabric 108A and flow widely toward the head HD of the wearer HM of the clothing 100 with a blower device.

[0151] <Regarding the flow of the air sent out by the blower device 1> Next, with reference to Fig. 26, the flow of the air sent out by the blower device 1 attached to the clothing 100 with a blower device will be described. Fig. 26 is an explanatory diagram for explaining the flow of the air sent out by the blower device attached to the clothing with a blower device shown in Fig. 17. In an example shown in Fig. 26, the wearer HM of the clothing 100 with a blower device is wearing a protective cap HL.

[0152] As shown in FIG. 26, air AR is blown from the outside of the clothing body 101 to the inside of the clothing body 101 by the blower devices 1 attached to two locations at the waist WS of the back part 104 of the clothing 100 with a blower device. Subsequently, as shown in FIG. 26, the air AR sent into the interior of the clothing body 101 by the blower device 1 circulates over a wide area inside the clothing body 101 and flows toward the collar 105 of the clothing 100 with a blower device.

[0153] As shown in FIG. 26, by the crotch air guiding part 108 disposed at the collar 105 of the clothing 100 with a blower device, a part of the air AR sent into the interior of the clothing body 101 passes through the allowable fabric 108A and flows toward the ears of the wearer HM of the clothing 100 with a blower device. Also, as shown in FIG. 26, by the crotch air guiding part 108 disposed at the collar 105 of the clothing 100 with a blower device, a part of the air AR sent into the interior of the clothing body 101 passes through the allowable fabric 108A and flows toward the back of the neck NK of the wearer HM of the clothing 100 with a blower device. Further, as shown in FIG. 26, a part of the air AR that has flowed to the back of the neck NK flows into the space between the protective cap HL worn by the wearer HM of the clothing 100 with a blower device and the head HD. As a result, by flowing into the space between the protective cap HL and the head HD, the sweat emitted from the head HD of the wearer HM can be evaporated, and the head HD of the wearer HM can be cooled by the heat of vaporization during evaporation.

[0154] <Regarding the air blowing operation unit> FIG. 27 is a block diagram showing the configuration of the air blowing operation unit provided in the clothing with a blower device according to the present embodiment. As shown in FIG. 27, the air blowing operation unit 200 includes an air blowing control unit 201, an air blowing operation unit 202, an air blowing display unit 203, and the like. Inside the air blowing operation unit 200, the air blowing operation unit 202 and the air blowing display unit 203 are electrically connected to the air blowing control unit 201.

[0155] The air supply operation unit 202 is configured in such a manner that by gently pressing with a finger the pressing portion on the upper surface of the air supply operation unit 200 based on a predetermined operation mode, an operation for controlling the on / off switching of energization to the motor of the drive unit 70 is made possible. The air supply display unit 203 is a display unit on the upper surface of the air supply operation unit 200 and is configured in such a manner that it can emit light in white.

[0156] Next, the operation and effects of the clothing with the air supply device according to this embodiment will be described.

[0157] The clothing 100 with the air supply device according to this embodiment has an air supply device 1 that sends air from the outside of the clothing body 101 to the inside of the clothing body 101, attached to the clothing body 101 formed by at least the front body 103, the back body 104, and the collar 105. The air supply device 1 has a blade 61 that sends air by rotation, and a guard 3 that covers the periphery of the blade 61 on the lower side of the blown air and is formed to be ventilable. At least a part of the upper end of the collar 105 is formed of a permissive fabric 108A that allows ventilation, and a crotch air guiding portion 108 for guiding the air sent into the clothing body 101 by the air supply device 1 toward the head HD of the wearer HM of the clothing 100 with the air supply device is provided, and the crotch air guiding portion 108 protrudes from the uppermost end of the collar 105.

[0158] According to the garment 100 with a blower device of the present embodiment, the blower device 1 blows air from the outside of the garment body 101 formed by at least the front body 103, the back body 104, and the collar 105 into the inside of the garment body 101. Thereby, while the air circulates inside the garment body 101, the sweat emitted from the upper body is evaporated, and the upper body of the wearer HM is cooled by the heat of vaporization during evaporation. Then, the crotch air guiding portion 108 formed of the allowable fabric 108A, which is disposed at the central portion of the upper end of the collar 105, protrudes from the uppermost end of the collar 105 and allows ventilation, guides the air cooled by the heat of vaporization toward the head HD of the wearer HM of the garment 100 with a blower device. Thereby, the head HD of the wearer HM can be cooled by the air cooled by the heat of vaporization. Therefore, not only is air sent from the outside of the garment body 101 into the inside of the garment body 101 to cool the upper body of the wearer HM by the heat of vaporization, but also the air cooled by the heat of vaporization can be effectively used to cool the head HD of the wearer HM. Therefore, for example, when a person who particularly requires cold air, such as a worker working outdoors in sweltering heat, wears the garment 100 with a blower device, the body can be cooled more efficiently than when wearing a garment with a blower device equipped with a blower device according to the prior art.

[0159] In addition, in the garment 100 with a blower device according to the present embodiment, the collar 105 is composed of an outer collar 106 and an inner collar 107 provided inside the outer collar 106. One end 108Aa of the allowable fabric 108A is fixed to the central portion OC of the upper end 106Aa of the outer collar 106, and the other end 108Ab of the allowable fabric 108A is fixed to the central portion IC of the upper end 107Aa of the inner collar 107, so that a wind guiding path through which the air sent into the inside of the garment body 101 by the blower device 1 circulates is formed in the crotch air guiding portion 108.

[0160] According to this aspect, by fixing one end 108Aa of the allowable fabric 108A to the central portion OC of the upper end 106Aa of the outer collar 106 and fixing the other end 108Ab of the allowable fabric 108A to the central portion IC of the upper end 107Aa of the inner collar 107, the wind cooled by the vaporization heat is circulated through the crotch side air duct 109 formed in the crotch air guiding portion 108. Thereby, the wind cooled by the vaporization heat can reach the head HD of the wearer HM. Therefore, it is possible to prevent the wind cooled by the vaporization heat from being dispersed from the collar 105, and the head HD of the wearer HM can be appropriately cooled by the wind reaching the head HD.

[0161] Further, in the clothing 100 with a blower according to the present embodiment, when no wind is flowing through the crotch side air duct 109 by the blower 1, the crotch air guiding portion 108 is in a flattened state, while when wind is flowing through the crotch side air duct 109 by the blower 1, the crotch air guiding portion 108 is in an expanded state.

[0162] According to the clothing 100 with a blower according to the present embodiment, when no wind is flowing through the crotch side air duct 109 by the blower 1, the crotch air guiding portion 108 is in a flattened state (see FIG. 24). Further, the crotch air guiding portion 108 has a semi-circular shape protruding toward the head HD of the wearer HM of the clothing 100 with a blower when the clothing 100 with a blower is worn by a person. Thereby, even if the crotch air guiding portion 108 comes into contact with the wearer HM's neck, it is less likely to cause a sense of discomfort in the crotch air guiding portion 108 than in the case of an expanded state. On the other hand, when wind is flowing through the crotch side air duct 109 by the blower 1, the crotch air guiding portion 108 is in an expanded state (see FIG. 25). Further, the crotch air guiding portion 108 has a semi-circular shape protruding toward the head HD of the wearer HM of the clothing 100 with a blower when the clothing 100 with a blower is worn by a person. Thereby, a large amount of wind that has circulated inside the clothing main body 101 and has been cooled by the vaporization heat can be sent into the head HD of the wearer HM by the crotch air guiding portion 108. Therefore, it is possible to change the state of the crotch air guiding portion 108 depending on whether the blower 1 is sending out wind or not, and to provide a comfortable clothing with a blower.

[0163] Further, in the garment 100 with a blower according to the present embodiment, the outer front part 106 is composed of an outer front fabric 106A that blocks ventilation, and the inner front part 107 is composed of a first inner front fabric 107A that blocks ventilation and a second inner front fabric 107B that allows ventilation. The other end 108Ab of the allowance fabric 108A is fixed to the central portion IC of the upper end 107Aa of the first inner front fabric 107A. A front-side air guide path 110 for guiding the air sent into the interior of the garment body 101 by the blower 1 to the crotch-side air guide path 109 is formed between the outer front part 106 and the inner front part 107.

[0164] According to the garment 100 with a blower according to the present embodiment, the air sent into the interior of the garment body 101 by the blower 1 passes through the second inner front fabric 107B and flows in, and circulates through the front-side air guide path 110 formed in the outer front part 106 and the inner front part 107. Thereafter, the air flowing through the front-side air guide path 110 does not escape from the first inner front fabric 107A and the outer front fabric 106A to the outside of the garment body 101, but flows into the crotch-side air guide path 109. Thereby, it is possible to prevent the air cooled by the latent heat of vaporization from flowing out to the outside of the garment body 101, and the air can cool the head HD of the wearer HM.

[0165] In the garment 100 with a blower according to the present embodiment, the guard 3 has one or more (three in the present embodiment) air direction adjustment members 50A, 50B, 50C (50). The air direction adjustment member 50 includes a laminar flow introduction part 51 including a first side surface 52 parallel to the rotation axis 71 of the wing 61, and a second side surface 57 (57A, 57B) that bends radially outward with the rotation axis 71 as the center and is connected to the first side surface 52 (52A, 52B). In the guard 3, the air direction adjustment members 50A, 50B, 50C (50) are adjacent to the gap 4 that becomes the air flow path FL with respect to the radial direction RD, and the first side surface 52 (52A, 52B) and the second side surface 57 (57A, 57B) are arranged at positions in contact with the air flow path FL.

[0166] According to the garment 100 with a blower device according to this embodiment, the directivity of the wind AR blown out from the guard 3 is expanded compared to the blower device according to the prior art in Patent Document 1 or the like, and the wind AR from the guard 3 blows out over a wider area in addition to the flow of the leeward side Fd along the axial direction AX.

[0167] In particular, when the blower device 1 is attached to the garment material 102 and the wind AR is blown from the blower device 1 to the body BS as in the garment 100 with a blower device illustrated in FIG. 18, the distance from the garment material 102 to which the blower device 1 is attached to the body BS inside is only about several centimeters. When the blower device 1 is used under such circumstances, the guard tip portion 3a of the guard 3 is in a state of contacting or approaching the body BS.

[0168] At this time, in the blower device according to the prior art such as Patent Document 1, the wind sent out from the propeller is a straight flow along the axial center direction of the propeller, and passes through the gap of the guard located on the leeward side most to be supplied to the body side. Therefore, the wind hits only the body side contact area facing the propeller mainly. Moreover, in the internal space between the garment material and the body, particularly in the vicinity of the tip of the guard, the air flow floating is affected by the flow of the wind sent from the propeller and the flow of the wind whose wind direction has changed when hitting the body side contact area, and becomes a turbulent flow due to the generation of vortices and mutually affects each other adversely.

[0169] Therefore, in the blower device according to the prior art, the wind sent from the propeller stays around the guard and does not reach widely over the surrounding area from the blower device to the space between the garment material and the body.

[0170] In contrast, in the blower 1 attached to the garment 100 with a blower according to the present embodiment, as shown in FIG. 13 and the like, the direction of the wind AR sent out from the blade 61 changes according to the bending angle θ of the second side surface 57 of the wind direction variable portion 56 by the wind direction adjusting member 50 in the flow path FL. Therefore, as illustrated in FIG. 18, even when the blower 1 mounted on the fabric 102 sends out the wind AR in a narrow space formed at a distance of only a few centimeters from the body BS, the wind AR reaches widely in the surrounding area from the blower 1.

[0171] Moreover, the wind AR sent out from the blade 61 does not stay around the guard 3, but flows around the blower 1 in the blower region STw widely diffused around the axis C through the gap 4 of the guard 3, as shown in FIGS. 13 and 18 and the like.

[0172] In addition, the wind AR sent out from the blade 61 reaches widely in the area around the blower 1. Therefore, the wearer HM can receive the wind AR supplied from the blower 1 not only in the central region facing the blade body 60 but also in the surrounding regions away from the central region of the body BS, improving the comfort of the wearer HM.

[0173] Therefore, according to the garment 100 with a blower according to the present embodiment, by rotating the blade 61, the direction of the wind AR sent out can be controlled so that the wind AR flows in a wider area on the leeward side FD of the blade 61, achieving an excellent effect. Furthermore, when a person who particularly requires cold wind, such as a worker working outdoors in sweltering heat or a worker wearing work clothes in a steamy indoor environment, a person engaged in recreation, sports, watching a game, etc. under the scorching sun, wears the garment 100 with a blower, the comfort can be improved more than when wearing a garment with a blower equipped with a blower according to the prior art.

[0174] In addition, in the garment 100 with a blower according to the present embodiment, the three wind direction adjusting members 50A, 50B, 50C (50) are arranged concentrically with the axis C of the rotating shaft 71 and intermittently overlap with each other across the gap 4 with respect to the radial direction RD.

[0175] According to the garment 100 with a blower according to the present embodiment, due to the rotation of the blades 61, the blown air AR includes a flow along the axial direction AX by the wind direction adjusting member 50 and is a flow that spreads sufficiently in the radial direction RD, and diffuses through the gap 4 of the guard 3 into a wide blowing area STw. Thereby, the upper body of the wearer HM of the garment 100 with a blower can receive the diffused air.

[0176] In addition, in the three wind direction adjusting members 50A, 50B, 50C (50) of the garment 100 with a blower according to the present embodiment, the angle of the second side surface 57A (57) formed relative to the first side surface 52A (52) increases from the inner side to the outer side of the radial direction RD for each of the wind direction adjusting members 50A, 50B, 50C (50).

[0177] According to the garment 100 with a blower according to the present embodiment, due to the rotation of the blades 61, the blown air AR includes a flow along the axial direction AX by the wind direction adjusting member 50 and is a flow that spreads sufficiently in the radial direction RD, and diffuses through the gap 4 of the guard 3 into a wide blowing area STw. Thereby, a wide range of the upper body of the wearer HM of the garment 100 with a blower can be exposed to the air.

[0178] In addition, the garment 100 with a blower according to the present embodiment is characterized in that the separation distance Dc between the blade downstream part 61P located on the most downstream side Fd of the blades 61 and the air inflow side end surface 53 located on the most upstream side Fw of the laminar flow introduction part 51 of the wind direction adjusting member 50 is at most 10 mm.

[0179] According to the garment 100 with a blower device according to this embodiment, due to the rotation of the blade 61, the wind AR sent to the leeward side Fd is a flow that includes a flow along the axial direction AX and spreads sufficiently in the radial direction RD by the wind direction adjusting member 50, and can be blown out in a mode of diffusing from the guard 3 to a wide blowing area STw.

[0180] Further, in the garment 100 with a blower device according to this embodiment, in the wind direction adjusting member 50, the wind inflow side end face 53 located most windward in the laminar flow introduction portion 51 and the first side face 52 are connected via an R-shaped inflow side curved surface 54.

[0181] According to the garment 100 with a blower device according to this embodiment, when the wind AR about to flow into the gap 4 reaches the first side face 52, the pressure loss of the air flow is reduced, the generation of vortices is suppressed by the inflow side curved surface 54, and the wind AR flows toward the second side face 57.

[0182] Further, in the garment 100 with a blower device according to this embodiment, in the wind direction adjusting member 50, the first side face 52 and the second side face 57 are connected via an R-shaped bending side curved surface 58.

[0183] According to the garment 100 with a blower device according to this embodiment, when the wind AR flowing into the gap 4 flows from the first side face 52 toward the second side face 57 and reaches the second side face 57 and passes through the gap 4, the pressure loss of the air flow is reduced, the generation of vortices is suppressed by the bending side curved surface 58, and the wind AR can be supplied to the outside.

[0184] Further, the garment 100 with a blower device according to this embodiment includes a drive unit that rotates the blade, and the guard 3 is formed on the outer periphery of the drive unit 70 disposed at the center in the radial direction RD.

[0185] According to the garment 100 with a blower device according to this embodiment, since the drive unit 70 is a part of the blower device 1 that does not send out the wind AR by the blades 61, the blower device 1 can be made compact. As a result, the space between the garment body 101 and the wearer HM can be effectively utilized, such as by providing a second cold insulation material storage portion 114B for containing the cold insulation material, and the usability of the garment 100 with a blower device equipped with the blower device 1 is good for the wearer HM.

[0186] Therefore, according to the garment 100 with a blower device according to this embodiment, the wind AR blown from the blower device 1 can achieve the excellent effect of improving the comfort of the garment 100 with a blower device for the dressed wearer HM.

[0187] In the above, the present disclosure has been described in accordance with the embodiments, but the present disclosure is not limited to the above embodiments, and can be appropriately modified and applied without departing from the gist thereof. Of course, the configurations according to the above embodiments and the following modification examples may be appropriately combined. The technical features of the above embodiments and the following modification examples can be appropriately deleted if they are not described as essential in this specification.

[0188] In the above embodiment, the collar air guiding portion 108 was sewn and fixed to the central portion of the upper end of the collar 105. However, it is not limited thereto. For example, the collar air guiding portion 108 may be sewn and fixed to the entire upper end of the collar 105. Thereby, the wind sent into the interior of the garment body 101 by the blower device 1 can be guided not only to the back of the head but also to the sides of the head and the front of the head. Further, for example, a plurality of collar air guiding portions 108 may be sewn and fixed to each of a plurality of portions at the upper end of the collar 105. In this case, for example, the plurality of collar air guiding portions 108 are sewn and fixed to two locations, namely, the right end portion and the left end portion at the upper end of the collar 105, respectively. Thereby, each of the plurality of collar air guiding portions 108 can guide the wind sent into the interior of the garment body 101 by the blower device 1 to the left side of the head and the right side of the head.

[0189] In the above-described embodiment, the crotch air guiding portion 108 was sewn and fixed to the central portion OC of the upper end 106Aa of the outer lapel 106 and the central portion IC of the upper end 107Aa of the inner lapel 107. However, it is not limited thereto. For example, the crotch air guiding portion 108 may be sewn and fixed to the entire upper end 106Aa of the outer lapel 106 and the entire upper end 107Aa of the inner lapel 107. Further, for example, a plurality of crotch air guiding portions 108 may be sewn and fixed to each of a plurality of portions of the upper end 106Aa of the outer lapel 106 and each of a plurality of portions of the upper end 107Aa of the inner lapel 107. In this case, for example, each of the plurality of crotch air guiding portions 108 is sewn and fixed to the left end portion and the right end portion of the upper end 106Aa of the outer lapel 106, respectively, and the left end portion and the right end portion of the upper end 107Aa of the inner lapel 107, respectively. Thereby, each of the plurality of crotch air guiding portions 108 can guide the air sent into the interior of the clothing body 101 by the air blower 1 to the left head and the right head.

[0190] In the above-described embodiment, the crotch air guiding portion 108 was in a semi-circular shape protruding toward the head HD of the wearer HM of the clothing 100 with a blower in a state where the person was wearing the clothing 100 with a blower, from the uppermost end 106Am of the outer lapel fabric 106A of the outer lapel 106 and the uppermost end 107Am of the first inner lapel fabric 107A of the inner lapel 107 (see FIGS. 15 to 20). However, it is not limited thereto. For example, the crotch air guiding portion 108 may be in a semi-circular shape protruding toward the outside of the outer lapel 106 from the uppermost end 106Am of the outer lapel fabric 106A of the outer lapel 106 and the uppermost end 107Am of the first inner lapel fabric 107A of the inner lapel 107. Thereby, it becomes difficult for the crotch air guiding portion 108 to contact the wearer HM's neck. Further, for example, the crotch air guiding portion 108 may be in a semi-circular shape protruding toward the wearer HM side from the uppermost end 106Am of the outer lapel fabric 106A of the outer lapel 106 and the uppermost end 107Am of the first inner lapel fabric 107A of the inner lapel 107. Thereby, for example, it is possible to prevent the crotch air guiding portion 108 from being caught by a tree branch or the like during work.

[0191] In the above-described embodiment, the inner collar 107 was composed of a first inner collar fabric 107A that blocks ventilation and a second inner collar fabric 107B that allows ventilation. However, it is not limited to this. For example, the inner collar 107 may be composed only of the second inner collar fabric 107B. Thereby, a large amount of air can be taken into the inner collar 107 made of the second inner collar fabric 107B by the air blower 1.

[0192] In the clothing 100 with an air blower in the above-described embodiment, the air blower 1 was attached. However, it is not limited to this. For example, an air blower related to the prior art in Patent Document 1 or the like may be attached to the clothing 100 with an air blower.

[0193] Note that the mode of the fabric 102 is not limited to a vest and can be variously changed. FIG. 15 illustrates a clothing 100 with an air blower to which two air blowers 1 are attached. However, the number of air blowers 1 attached to the fabric 102 is merely an example of 2 and is not limited to this embodiment and can be appropriately changed.

[0194] For example, in the embodiment, the air blower fan that sends air by the rotation of the blades was a propeller fan composed of the blade body 60. However, the air blower fan may be, for example, an axial flow fan, a turbo fan, a sirocco fan, etc. configured with a structure different from that of the blade body 60.

[0195] Also, in the embodiment, the guard 3 in which three air direction adjusting members 50 were formed was cited. However, the quantity of the air direction adjusting members provided on the guard is not limited to three and may be, for example, one case or four or more cases, and can be appropriately changed.
