Description

[Technical Field]

[0001] The present disclosure relates to body temperature regulating clothing, such as a jacket or vest, that regulates the temperature of the wearer's body using a Peltier element unit. [Background technology]

[0002] In recent years, there have been many extremely hot days throughout the year that are uncomfortable for people, and on such extremely hot days, measures to prevent heatstroke, such as frequent hydration and the appropriate use of air conditioners, are recommended. However, due to reasons such as the lack of air conditioner equipment or insufficient air conditioning, workers working outdoors in the heat of the day, workers working in humid indoor environments, and people participating in recreational activities, sports, or watching games under the blazing sun cannot cool down with air conditioners. Patent Document 1 discloses an example of a solution to this problem.

[0003] Patent Document 1 discloses a body temperature regulator in which a holder is attached to a person's neck, and the area around the neck is cooled or warmed by a heat transfer surface that is cooled or heated by a Peltier element. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Design Registration No. 1730739 Summary of the Invention [Problem to be solved by the invention]

[0005] The technology of Patent Document 1 has the problem that it is difficult to adjust the position of the heat transfer surface that comes into contact with the person's neck depending on the physique and movement of the person wearing the body temperature regulator, and therefore it is not possible to efficiently regulate the temperature of the person's body.

[0006] The present disclosure has been made to solve the above-mentioned problems, and aims to provide body temperature regulating clothing that efficiently regulates the temperature of a person's body by adjusting the position of the heat transfer surface that comes into contact with the person's neck according to the person's physique and movement. [Means for solving the problem]

[0007] In one aspect of the present disclosure, which has been made to solve the above problems, there is provided body temperature regulating clothing having Peltier elements and capable of attaching one or more Peltier element units to the collar, each Peltier element unit having a heat transfer surface that cools or heats using the Peltier element. The clothing body is made up of at least a front body, a back body, and the collar, and the collar is made up of an outer collar and an inner collar attached to the inside of the outer collar. The inner collar is provided with an attachment section to which the Peltier element unit can be attached, and an adjustment section that changes and adjusts the position of the heat transfer surface in the circumferential direction around a person's neck, and the adjustment section is made of a stretchable material.

[0008] The clothing referred to in this disclosure is broadly divided into (a) outerwear such as jackets, jumpers, suits, vests, etc., (b) underwear such as pants, trousers, etc., and (c) items worn on the feet or legs such as socks, foot warmers, etc., and is a general term that includes each of (a), (b), and (c).

[0009] It should be noted that the stretchable material according to the present disclosure is a material that can stretch and shrink, and has elasticity such as rubber, and examples of such materials include nylon, polyester, and the like.

[0010] According to this aspect, the collar adjustment portion of the body temperature regulating garment is made of a stretchable material, so that the position of the heat transfer surface of the Peltier element unit attached to the attachment portion of the inner collar of the body temperature regulating garment can be adjusted circumferentially around the neck of the person wearing the body temperature regulating garment to suit the physique and movements of the person wearing the body temperature regulating garment. This allows the adjustment portion to stretch and contract to suit various body sizes, allowing the heat transfer surface to appropriately contact the person's neck and efficiently regulating the person's body temperature. Furthermore, the adjustment portion can stretch and contract to suit various movements of the person, allowing the heat transfer surface to appropriately contact the person's neck and efficiently regulating the person's body temperature.

[0011] In the above aspect, it is preferable that the mounting portion includes a first mounting portion to which the first Peltier element unit can be mounted and a second mounting portion to which the second Peltier element unit can be mounted, and that the adjustment portion is provided between the first mounting portion and the second mounting portion.

[0012] According to this aspect, when regulating the temperature of a person's neck using the heat transfer surface of the first Peltier element unit attached to the first attachment part and the heat transfer surface of the second Peltier element unit attached to the second attachment part, the adjustment part provided between the first attachment part and the second attachment part expands and contracts to match the physique and movements of the person wearing the body temperature regulating garment. This allows the heat transfer surfaces of the first Peltier element unit and the second Peltier element unit to be in appropriate contact with the person's neck for various body sizes and various movements, thereby more efficiently regulating the temperature of the person's neck.

[0013] In the above aspect, it is preferable that the adjustment portion be provided on at least one of the left and right end portions of the collar.

[0014] According to this aspect, the position of the heat transfer surface can be adjusted by expanding and contracting the adjustment part provided on at least one of the left and right ends of the collar to suit the physique and movements of the person wearing the body temperature regulating garment. This allows the heat transfer surfaces of the first Peltier element unit and the second Peltier element unit to be brought into more appropriate contact with the person's neck for various body sizes and movements, thereby efficiently regulating the temperature of the person's neck.

[0015] In the above aspect, it is preferable that a blower device that blows air from the outside of the main body of the clothing into the inside of the main body of the clothing can be attached to the body temperature regulating clothing, at least a portion of the upper end of the collar is made of a permeable fabric that allows ventilation, and an air guide section is arranged to guide the air sent into the main body of the clothing by the air blower toward the head of the wearer of the body temperature regulating clothing, and that the air guide section protrudes from the uppermost end of the collar.

[0016] Note that the permissive fabric that allows ventilation according to the present disclosure is a fabric that has gaps that allow air to pass from one side of the permissive fabric to the other, and allows air to pass from one side of the permissive fabric to the other. Specifically, examples of permissive fabric that allows ventilation include fabrics with a mesh structure in which gaps are formed in the permissive fabric by weaving or knitting methods, and fabrics that have been processed to provide through holes that allow air to pass from one side of the permissive fabric to the other. Note that examples of materials for permissive fabrics that allow ventilation include nylon, polyester, etc.

[0017] According to this aspect, air sent from the outside of the garment body to the inside of the garment body by the air blower is directed toward the head of the person wearing the body temperature regulating garment through an air guide section disposed at least partially on the top edge of the collar, extending beyond the top edge of the collar and made of a permeable fabric that allows ventilation. This allows the air sent from the outside of the garment body to the inside of the garment body to cool, for example, parts of the wearer's body inside the garment body, and efficiently cool the person's neck that comes into contact with the heat transfer surface. Furthermore, by circulating through the air guide section extending beyond the top edge of the collar, the air sent into the inside of the garment body is prevented from being dispersed from the collar, and the air can also cool the wearer's head.

[0018] In the above aspect, it is preferable that the collar is composed of an outer collar and an inner collar provided inside the outer collar, the inner collar is provided with the attachment part and the adjustment part, and by fixing one end of the allowable fabric to at least a part of the upper end of the outer collar and fixing the other end of the allowable fabric to at least a part of the upper end of the inner collar, an air guide path is formed within the air guide part through which the air sent into the inside of the garment body by the air blower circulates.

[0019] According to this aspect, the air sent into the inside of the garment body by the air blower flows through an air guide channel formed in the air guide section by fastening one end of the air-permeable fabric to at least a portion of the upper end of the outer collar and the other end of the air-permeable fabric to at least a portion of the upper end of the inner collar where the attachment section and the adjustment section are provided, and is guided to the wearer's head. As a result, for example, air sent inside the garment body can be guided to the air guide section without being released to the outside of the garment body, thereby cooling the person's head and efficiently cooling the person's neck that comes into contact with the heat transfer surface.

[0020] In the above aspect, it is preferable that the outer collar is made of an outer collar fabric that blocks ventilation, and that a collar-side air guide channel is formed between the outer collar and the inner collar to guide the air sent into the inside of the garment body by the air blower into the air guide channel.

[0021] The ventilation-blocking outer collar fabric of the present disclosure is a fabric that does not have any gaps that would allow air to pass from one side of the outer collar to the other, preventing air from passing from one side to the other. Examples of ventilation-blocking outer collar fabric materials include nylon and polyester.

[0022] According to this configuration, the air sent into the main body of the garment by the air blower flows through the collar-side air guide channels formed in the outer and inner collar, and flows into the air guide channels without flowing from the outer collar fabric to the outside of the main body of the garment. This efficiently cools the person's neck, which comes into contact with the heat transfer surface, and prevents the air sent into the main body of the garment by the air blower from being released to the outside of the main body of the garment from the outer collar fabric, allowing the person's head to be cooled by the air guided from the air guide section.

[0023] In the above aspect, the Peltier element unit preferably comprises a main body that houses the Peltier element, a heat exchange surface opposite the heat transfer surface, an intake hole that takes in air from outside the main body, and an exhaust hole that exhausts the air that has been heat exchanged on the heat exchange surface, and when the Peltier element unit is attached to the attachment part, the exhaust hole is preferably arranged within the collar-side air guide duct.

[0024] According to this configuration, air is taken in through the intake holes in the main body of the Peltier element unit attached to the inner collar attachment section, and the air that has exchanged heat on the heat exchange surface is exhausted into the collar-side air guide channel through the exhaust holes arranged in the collar-side air guide channel. As a result, the air exhausted from the exhaust holes merges with the air sent into the garment body by the air blower and is guided into the air guide channel, allowing the air guided through the air guide channel to cool the person's head. [Effects of the Invention]

[0025] Therefore, the body temperature regulating clothing disclosed herein has the excellent effect of providing body temperature regulating clothing that efficiently regulates the temperature of a person's body by adjusting the position of the heat transfer surface that comes into contact with the person's neck in accordance with the person's physique and movement.

DETAILED DESCRIPTION OF THE INVENTION

[0027] The Peltier element unit, air blower, and body temperature regulating clothing according to the present disclosure will be described in detail below with reference to embodiments. The Peltier element unit according to the present disclosure can regulate body temperature by bringing a heat transfer surface cooled or heated by a Peltier element into direct contact with the body or indirectly via underwear or the like. The air blower according to the present disclosure is a fan unit that supplies air toward the body, for example, through a guard by rotating blades. The body temperature regulating clothing according to the present disclosure is configured by attaching the air blower and Peltier element unit according to the present disclosure to the clothing fabric, and can blow air toward the body using the air blower, while the Peltier element unit can regulate the temperature of the wearer's body.

[0028] First, the configuration of the air blower 1 will be described. Fig. 1 is a perspective view of the air blower seen from the air blowing side. Fig. 2 is a cross-sectional view taken along the line AA in Fig. 1, showing a part of the air blower seen from the side. Fig. 3 is an exploded perspective view of the air blower shown in Fig. 1.

[0029] 1 and 2, the vertical direction of the blower 1 according to this embodiment is defined as the axial direction AX along the axis C, and in FIG. 2, the direction perpendicular to the axial direction AX is defined as the radial direction RD, and the circumferential direction around the axis C along the axial direction AX is defined as the circumferential direction CR. The directions defined in FIGS. 1 and 2 are also used in the figures from FIG. 3 onwards. Furthermore, the power source (battery), electrical wiring, connectors, etc. required for the blower 1 are not shown in the figures.

[0030] 1 to 3, the blower 1 includes a case body 2, a blade body 60, a drive unit 70, etc. For example, the blower 1 corresponds to the blower according to the present disclosure.

[0031] <About the Wing Body 60 and the Drive Unit 70> As shown in Fig. 3, the blade body 60 is made up of a boss portion 62 and blades 61. The blade body 60 is a propeller fan that can rotate around a rotary shaft 71 disposed on the axis C by a drive unit 70 that includes the rotary shaft 71, its bearing, an electric motor, etc. The blade body 60 and drive unit 70 are housed in the case internal space 30S.

[0032] A power supply connector 72 is provided in the blower-side case 30. The power supply connector 72 is formed so as to be detachable from a power supply-side connector (not shown), such as a plug, that electrically connects to a power source. Electricity is supplied to the drive unit 70 via the power source through conduction between the power supply-side connector and the power supply connector 72.

[0033] In this embodiment, nine blades 61 are connected to the boss portion 62. The number of blades 61 connected to the boss portion 62 is not limited to nine, and may be, for example, five, seven, or an odd number greater than nine. This is because when the blade body is made up of an odd number of blades, vibrations that occur when the blades rotate are reduced compared to when an even number of blades are used.

[0034] Furthermore, when the number of blades 61 is increased from 5 to, for example, 7 or 9, the twist angle of each blade 61 connecting to boss portion 62 inevitably becomes larger compared to when the number is 5. When the twist angle of blade 61 becomes larger, air is sent out from almost the entire surface area of ​​blade 61, which makes it easier to make the air pressure distribution on the surface of blade 61 more uniform, and also reduces noise during air blowing.

[0035] Furthermore, when the number of blades 61 is 7 or 9, the distance between adjacent blades 61 is smaller than when there are 5. Therefore, it is possible to minimize interruptions in the airflow continuously blown out from each blade 61, even if only slightly, and the wind becomes a smooth airflow with controlled strength, and is blown out in a manner that feels gentle on the skin of the person receiving the wind.

[0036] <Regarding the intake side case portion 10> The case body 2 is composed of an intake side case portion 10 and a blower side case portion 30. The intake side case portion 10 has an intake side flange 11, an intake side peripheral wall portion 12, an intake portion 13, and the like.

[0037] The intake side flange 11 is formed in an annular shape, and the inner circumferential side of this intake side flange 11 forms the intake section 13. The intake section 13 has an intake port 14 that takes in wind AR into the case main body 2. In this embodiment, as shown in FIG. 2 , the intake section 13 is formed in a shape that gently rises from the inner circumferential side of the intake side flange 11 toward the center passing through the axis C, with a height difference M of, for example, about 3 mm.

[0038] However, it is preferable that the height difference M of the intake section 13 is closer to 0 mm. As will be described later, when the air blower 1 is attached to clothing, if the intake section has a height difference M of, for example, 10 mm or more, the intake section of the air blower device is likely to come into contact with surrounding obstacles. In addition, the movement of the wearer of the clothing is affected by the protrusion of the intake section of the air blower device. For this reason, if the intake section 13 of the intake-side case 10 has a flatter shape, it is easier to avoid contact with surrounding obstacles and reduce adverse effects on the movement of the wearer of the clothing.

[0039] The intake-side peripheral wall portion 12 is integral with the intake-side flange 11 and stands cylindrically from the radially inner peripheral edge of the intake-side flange 11. As shown in Figures 2 and 3, the outer peripheral surface 12a of the intake-side peripheral wall portion 12 is provided with protrusions 20 in a distributed arrangement at multiple locations in the circumferential direction and the axial direction AX.

[0040] <About the blower-side case portion 30> 1 to 3, the air-blowing-side case 30 includes a guard 3, an air-blowing-side flange 31, an air-blowing-side peripheral wall 32, and a case internal space 30S surrounded by the air-blowing-side peripheral wall 32. The air-blowing-side flange 31 is formed in an annular shape. The air-blowing-side peripheral wall 32 is integral with the air-blowing-side flange 31 and stands cylindrically from the inner periphery of the air-blowing-side flange 31.

[0041] The outer peripheral surface 32a of the air-blowing-side peripheral wall 32 has a gripping portion 33 formed around the entire circumference in the circumferential direction CR in a pattern of alternating concave and convex portions. This allows a person wanting to wear the air blower 1 in the body temperature regulating garment 100 to rotate the air-blowing-side case 30 by hand relative to the air-suction-side case 10 around the axis C, allowing the person to firmly grasp the gripping portion 33 with their fingers without slipping. This makes it easy for the wearer to rotate the air-blowing-side case 30 with their fingers.

[0042] <Assembling the Intake Side Case 10 and the Blower Side Case 30> Fig. 4 is an explanatory diagram showing a plan view of fixed guides formed in the air blower according to the embodiment. As shown in Fig. 3, a plurality of fixed guides 40 are arranged on the inner peripheral surface 32b of the air blowing-side peripheral wall portion 32. The diameter of the inner peripheral surface 32b of the air blowing-side peripheral wall portion 32 is larger than the outer diameter of the protruding pieces 20 provided on the outer peripheral surface 12a of the air intake-side peripheral wall portion 12, and is sized so that the protruding pieces 20 and the fixed guides 40 can engage with each other.

[0043] 4, when viewed from the axial direction AX, the fixed guide 40 extends in an arc shape between one end 41a and the other end 40b along the inner circumferential surface 32b of the blower-side peripheral wall portion 32, and when viewed from the radial direction RD, is inclined at an angle θ1 from the horizontal. In the fixed guide 40, the one end 41a and the other end 40b have a height difference H in the axial direction AX. The multiple fixed guides 40 are spaced apart at a predetermined pitch that matches the dimensions of the protrusions 20 and are arranged intermittently in the axial direction AX.

[0044] The fixed guide 40 has a stopper 44 at the other end 40b on the sliding side of the protrusion piece 20 formed on the outer peripheral surface 12a of the intake side peripheral wall portion 12, with the lead direction Le being arranged in the following order from the one end 41a side: introduction surface 41, first regulating surface 43a, first retaining surface 42a, second regulating surface 43b, second retaining surface 42b, third regulating surface 43c, third retaining surface 42c, fourth regulating surface 43d, fourth retaining surface 42d, fifth regulating surface 43e, and fifth retaining surface 42e.

[0045] 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 smooth surface shape and serve as surfaces for holding the protruding piece 20. The first restricting surface 43a, the second restricting surface 43b, the third restricting surface 43c, the fourth restricting surface 43d, and the fifth restricting 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.

[0046] The first restriction surface 43a, the second restriction surface 43b, the third restriction surface 43c, the fourth restriction surface 43d, and the fifth restriction surface 43e and the stopper 44 restrict the movement of the protrusion 20 arranged on a holding surface such as the first holding surface 42a in the lead direction Le from both sides of the protrusion 20. In addition, the movement of the protrusion 20 arranged on a holding surface such as the first holding surface 42a is restricted in the axial direction AX by contact with the adjacent fixed guide 40.

[0047] In the blower device 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 relatively about the axis C. While the intake-side case portion 10 and the blower-side case portion 30 rotate relatively about the axis C, the protrusions 20 of the intake-side case portion 10 and the fixed guides 40 of the blower-side case portion 30 are engaged and positioned. In this way, the intake-side case portion 10 and the blower-side case portion 30 are assembled.

[0048] In the blower device 1, the axial separation distance AX between the intake side flange 11 of the intake side case portion 10 and the blowing side flange 31 of the blowing side case portion 30 varies depending on the position of the holding surface that holds the protrusion piece 20, among the first holding surface 42a, second holding surface 42b, third holding surface 42c, fourth holding surface 42d, and fifth holding surface 42e on the fixed guide 40.

[0049] Figure 5 is an explanatory diagram showing an example of a state in which the protrusion is engaged with the fixed guide in the blower device of the embodiment, and shows the case of fixed position A, where the flange of the intake side case part and the flange of the blower side case part are furthest apart.

[0050] As an example, as shown in Figure 5, when the protrusion piece 20 sliding from the introduction surface 41 is positioned by the fixed guide 40 and the first retaining surface 42a located between the first regulating surface 43a and the second regulating surface 43b, the intake side flange 11 and the blowing side flange 31 are spaced apart at the largest flange-to-flange distance K1, resulting in a fixed position A.

[0051] The air blower 1 is capable of varying the distance in the axial direction AX between the intake-side flange 11 of the intake-side case 10 and the air-blowing-side flange 31 of the air-blowing-side case 30. Therefore, when the air blower 1 is attached by sandwiching the peripheral portion 122 of the fabric 102 between the intake-side flange 11 and the air-blowing-side flange 31, as in the body temperature regulating clothing 100 described below, the thickness of the gripped portion, such as the peripheral portion 122, that can be sandwiched can be adjusted to a wide range.

[0052] <About Guard 3> As shown in FIGS. 1 to 3, the guard 3 is formed on the outer periphery of the drive unit 70, which is located at the center in the radial direction RD, on the opposite side of the blowing-side flange 31 in the axial direction AX. The guard 3 covers the blades 61, which blow air by rotation, and the leeward side Fd of the blown air, and allows ventilation through the gap 4. The guard 3 is formed in a manner that covers the case internal space 30S surrounded by the blowing-side peripheral wall 32, from the inner periphery of the blowing-side peripheral wall 32 toward the center passing through the axis C. The air blown out from the blades 61 passes through the guard 3 and is supplied to the outside.

[0053] The guard 3 has one or more airflow direction adjusting members 50, and in this embodiment, three airflow direction adjusting members 50A, 50B, 50C (50) are formed on the guard 3 as shown in FIGS.

[0054] Each of the three airflow direction adjustment members 50A, 50B, 50C (50) comprises a laminar flow introduction section and an airflow direction changing section. The laminar flow introduction section is a plate-shaped section including a first side surface that is arranged parallel to the rotation axis 71 of the blade body 60, i.e., along the axial direction AX.

[0055] The airflow direction changing section is formed integrally with and connected to the laminar flow introduction section. The airflow direction changing section is a plate-shaped section including a second side surface that is bent from a first side surface outward in the radial direction RD centered on the axis C.

[0056] In the guard 3, all three airflow direction adjustment members 50A, 50B, 50C (50) are arranged in an arc shape in the circumferential direction CR around the axis C. The three airflow direction adjustment members 50A, 50B, 50C (50) are arranged concentrically about the axis C and intermittently overlap with gaps 4 in between in the radial direction RD.

[0057] That is, each of the airflow direction adjustment members 50A, 50B, 50C (50) is adjacent to the gap 4, which serves as the airflow path, in the radial direction RD. The first and second side surfaces of the airflow direction adjustment members 50A, 50B, 50C (50) are arranged in positions that contact the airflow path.

[0058] In addition, in the three airflow direction adjustment members 50A, 50B, 50C (50), the bending angle, which is the angle of the second side surface relative to the first side surface, increases from the inner side in the radial direction RD to the outer side in the radial direction RD for each airflow direction adjustment member 50.

[0059] In all three airflow direction adjustment members 50A, 50B, 50C (50), the airflow inlet end face located most windward of the laminar flow introduction section is connected to the first side face via an R-shaped inlet curved surface.

[0060] The radius of curvature of the inlet-side curved surface is a proportion of the distance (thickness) between the opposing first side surfaces, and is, for example, a size equivalent to 10 to 50%. In this embodiment, the radius of curvature of the inlet-side curved surface is approximately 30% of the thickness between the first side surfaces. Note that the connection between the inlet-side end surface and the first side surface, and the connection between the inlet-side end surface and the first side surface, may be made by a C-chamfered surface.

[0061] Furthermore, in each of the three airflow direction adjustment members 50A, 50B, 50C (50), the first side surface and the second side surface located on the outer side in the radial direction RD are connected via an R-shaped bent-side curved surface.

[0062] <Regarding the positional relationship between the wind direction adjustment member 50 and the blades 61> In the blower 1, the three airflow direction adjustment members 50A, 50B, 50C (50) are arranged on the downwind side of the blade 61 of the blade main body 60. In the axial direction AX, the distance between the downwind portion of the blade 61 located on the most downwind side and the wind inlet side end face located on the most upwind side Fw of the laminar flow introduction part of the airflow direction adjustment member 50 is at most 10 mm or less.

[0063] Specifically, of the three airflow direction adjustment members 50A, 50B, 50C (50), in the case of the first airflow direction adjustment member 50A (50), which is located closest to the axis C, the distance between the downwind portion of the blade and the wind inlet end face is approximately 7 mm. In addition, in the case of the third airflow direction adjustment member 50C (50), which is located farthest from the axis C, the distance Dc between the downwind portion of the blade and the wind inlet end face is approximately 2 mm.

[0064] <About the Peltier element unit 80> Next, the Peltier element unit 80 will be described with reference to Figs. 6 to 8. Fig. 6 is an explanatory diagram showing the Peltier element unit from the ceiling side of the body temperature regulating clothing. Fig. 7 is an explanatory diagram showing the Peltier element unit from the heat transfer surface side of the body temperature regulating clothing. Fig. 8 is an exploded perspective view showing the configuration of the Peltier element unit. Furthermore, in each drawing, the power source (battery), electrical wiring, connectors, etc. necessary for the Peltier element unit 80 are omitted from the illustration.

[0065] 8 and 9, the vertical direction is defined as the axial direction AX along the axis C, with the upper side being the upper side Lp and the lower side being the lower side Lw. In the Peltier element unit 80 according to this embodiment, in Fig. 8 and 9, the direction perpendicular to the axial direction AX is defined as the radial direction RD, the circumferential direction centered on the axis C along the axial direction AX is defined as the circumferential direction CR, and the anti-circumferential direction centered on the axis C along the axial direction AX is defined as the anti-circumferential direction ACR. The directions defined in Fig. 8 and 9 also apply to each of the figures from Fig. 9 onwards.

[0066] As shown in FIGS. 6 to 8, the Peltier element unit 80 has a Peltier element PE (an example of a Peltier element according to the present disclosure) built into a main body 82. The Peltier element PE is a type of plate-shaped semiconductor thermoelectric element. When a direct current is supplied to the Peltier element PE, one surface PEA of the flat plate portion of the Peltier element PE absorbs heat to, for example, about 10°C due to the Peltier effect, and enters an endothermic state (cooled surface). At the same time, the other surface PEB on the opposite side generates heat to, for example, about 30°C, and enters a heat-generating state (heated surface). The Peltier element is an element that transfers heat from the cooled surface to the heated surface, generating a large amount of heat on the heated surface side.

[0067] In this embodiment, the Peltier element PE has the property of absorbing heat and generating heat simultaneously relative to the outside air temperature in a temperature range of, for example, about 20 to 30° C. For example, the Peltier element PE corresponds to the Peltier element according to the present disclosure.

[0068] For example, when a Peltier element PE is operating in summer at an outside temperature of 35°C, the cooling surface generates heat of 15-15°C, which is used to cool the body. At the same time, the heating surface generates heat of 55-65°C, which is used as exhaust heat.

[0069] On the other hand, when the Peltier element PE is operating in winter at an outside temperature of 5°C, the cooling surface generates heat of -15 to -25°C, which is used as waste heat. At the same time, the heating surface generates heat of 25 to 35°C, which is used as warmth to warm the body.

[0070] As shown in FIGS. 6 to 8, the Peltier element unit 80 has a heat transfer surface 81 (cooling surface 81A or heating surface 81B) which is one surface thereof, a circular ceiling portion 91, a cylindrical portion 84, and a main body portion 82 that houses the Peltier element PE. The Peltier element unit 80 also has a heat exchange surface 93 on the opposite side of the heat transfer surface 81. For example, the Peltier element unit 80 corresponds to the Peltier element unit according to the present disclosure, and the heat transfer surface 81 corresponds to the heat transfer surface according to the present disclosure. For example, the main body portion 82 corresponds to the main body portion according to the present disclosure.

[0071] As shown in Figures 6 and 7, the cylindrical portion 84 has a plurality of (e.g., four) intake portions 85 formed at intervals in the circumferential direction. Each of the plurality of (e.g., four) intake portions 85 has a plurality of (e.g., eight) intake holes 85a formed at intervals in the circumferential direction. The plurality of (e.g., eight) intake holes 85a are holes formed to take air from outside the main body portion 82 into the main body portion 82. For example, the intake holes 85a correspond to the intake holes according to the present disclosure.

[0072] 7 and 8, the ceiling portion 91 closes the internal space surrounded by the main body portion 82 on the side opposite the heat transfer surface 81. As shown in FIG. 7, the ceiling portion 91 is formed with a plurality of exhaust holes 92 for discharging air that has undergone heat exchange by the heat exchange surface 93 to the outside of the Peltier element unit 80. The plurality of exhaust holes 92 are holes formed for discharging air taken in through the intake holes 85a at a plurality of locations (e.g., eight locations) to the outside of the main body portion 82. For example, the exhaust holes 92 correspond to the exhaust holes according to the present disclosure, and the heat exchange surface 93 corresponds to the heat exchange surface according to the present disclosure.

[0073] As shown in Fig. 8, the Peltier element unit 80 also has a heat exchange surface 93 that exchanges heat by taking in heat from the Peltier element PE and dissipating it into the air, and an annular inner flange 83 formed on the cover member of the main body 82. Furthermore, as shown in Fig. 8, the Peltier element unit 80 also has a heat exhaust device 94 that takes in air through an intake hole 85a and sends it toward an exhaust hole 92, and a ring fastener 130. The heat exhaust device 94 blows the air that has undergone heat exchange on the heat exchange surface 93 out of the Peltier element unit 80 through the multiple exhaust holes 92. The heat exhaust device 94 can exhaust the air that has been taken in through the multiple intake holes 85a and that has undergone heat exchange on the heat exchange surface 93 from the multiple exhaust holes 92 by the rotation of a propeller 95.

[0074] As shown in Fig. 8, the ring fastener 130 is formed so as to be freely fastened to and detached from the main body portion 82, which is the end portion opposite the heat transfer surface 81 (cooling surface 81A or heating surface 81B). The ring fastener 130 is made of synthetic resin and has an annular outer flange 131 formed in a substantially polygonal shape. As shown in Fig. 13, the outer flange 131 has twelve elliptical holes formed therein. The inner diameter of the ring fastener 130 is larger than the outer diameter of the ceiling portion 91 and smaller than the outer diameter of the inner flange 83.

[0075] Protrusions 132 connectable to the plurality of fixed guides 86 are disposed on the inner peripheral surface 130a of the ring fastener 130. Each of the plurality of protrusions 132 is easily connectable to each of the plurality of fixed guides 86. In the body temperature regulating garment 100, the first Peltier element unit 80A is attached to the first attachment portion 109A, and the second Peltier element unit 80B is attached to the second attachment portion 109B. For example, the attachment portion 109 corresponds to the attachment portion according to the present disclosure, and for example, the first attachment portion 109A corresponds to the first attachment portion according to the present disclosure, and for example, the second attachment portion 109B corresponds to the second attachment portion according to the present disclosure.

[0076] The heat transfer surface 81 is exposed to the outside, and the heat transfer surface 81 and the ceiling portion 91 are arranged on opposite sides of each other in the Peltier element unit 80. The heat transfer surface 81 is made of, for example, stainless steel or a metal with excellent thermal conductivity.

[0077] The heat exchange surface 93 formed on the back side of the heat transfer surface 81 is made of a metal with excellent thermal conductivity, such as aluminum or copper. The heat exchange surface 93 has a plurality of (e.g., 117) heat dissipation fins 93a configured in a protruding shape. Because the heat dissipation fins 93a are configured in a protruding shape, the surface area of ​​the heat dissipation fins 93a is increased, thereby expanding the area that comes into contact with the air, allowing for efficient dissipation of heat from the Peltier element. On the heat exchange surface 93, the heat dissipation fins 93a are aligned at regular intervals so that air flowing in from the air intake holes 85a can pass between the heat dissipation fins 93a. As a result, for example, cooling air flowing in between the heat dissipation fins 93a comes into contact with the heat dissipation fins 93a, allowing efficient exchange of heat from the Peltier element PE.

[0078] 8, a heat transfer surface 81 (cooling surface 81A or heating surface 81B) is provided at an end opposite to the main body 82 in an axial direction AX along the axis C of the main body 82. The main body 82 is formed in a cylindrical shape, and is provided with an inner flange 83 that protrudes in the shape of an annular plate from the outer peripheral end.

[0079] <Assembling the main body 82 and the ring fastener 130> Fig. 9 is an explanatory diagram showing a plan view of a guide rail formed in a Peltier element unit according to the embodiment. As shown in Fig. 8, a plurality of fixed guides 86 are arranged on an outer peripheral surface 82a of the main body 82. The diameter of the outer peripheral surface 82a of the main body 82 is larger than the outer diameter of the protrusions 132 provided on the inner peripheral surface 130a of the ring fastener 130, and is sized so that the protrusions 132 and the fixed guides 86 can engage with each other.

[0080] As shown in Fig. 9, the four fixed guides 86 each have a gap 90 between adjacent fixed guides 86. A plurality of gaps 90 (for example, four) are provided on the outer peripheral surface 82a of the main body 82. As shown in Fig. 9, the gaps 90 are connected to a mounting groove portion 89.

[0081] 9, when viewed from the axial direction AX, the fixed guide 86 extends between one end 86a and the other end 86b in an arc shape that follows the outer circumferential surface 82a of the main body 82, and when viewed from the radial direction, is inclined at an angle θ2 from the horizontal. In the fixed guide 86, the one end 86a and the other end 86b have a height difference H in the axial direction AX. The multiple fixed guides 86 are spaced apart at a predetermined pitch that matches the dimensions of the protrusions 132 and are arranged intermittently in the axial direction AX.

[0082] The fixed guide 86 has a stopper 87d at the other end 86b on the sliding side of the protrusion 132 formed on the inner surface 130a of the ring fastener 130, with the lead direction Le being passed through, in order from the one end 86a side, an introduction surface 97, a first regulating surface 87a, a first holding surface 88a, a second regulating surface 87b, a second holding surface 88b, a third regulating surface 87c, and a third holding surface 88c.

[0083] The first holding surface 88a, the second holding surface 88b, and the third holding surface 88c are formed in a smooth surface shape and serve as surfaces for holding the protruding piece 132. The first restricting surface 87a, the second restricting surface 87b, and the third restricting surface 87c are formed in a mountain shape protruding from the first holding surface 88a, the second holding surface 88b, and the third holding surface 88c.

[0084] The first restricting surface 87a, the second restricting surface 87b, the third restricting surface 87c, and the stopper 87d restrict the movement of the protrusion 132 arranged on a holding surface such as the first holding surface 88a in the lead direction Le from both sides of the protrusion 132. In addition, the movement of the protrusion 132 arranged on a holding surface such as the first holding surface 88a is restricted in the axial direction AX by contact with the adjacent fixed guide 86.

[0085] In the Peltier element unit 80, the outer peripheral surface 82a of the main body 82 is inserted into the ring fastener 130, and the main body 82 and the ring fastener 130 rotate relatively around the axis C. While the main body 82 and the ring fastener 130 rotate relatively around the axis C, the protrusion 132 of the ring fastener 130 and the fixed guide 86 of the main body 82 are engaged and positioned. In this way, the main body 82 and the ring fastener 130 are assembled.

[0086] In the Peltier element unit 80, the axial distance AX between the inner flange 83 of the main body 82 and the outer flange 131 of the ring fastener 130 changes depending on the position of the holding surface that holds the protrusion piece 132, among the first holding surface 88a, the second holding surface 88b, and the third holding surface 88c on the fixed guide 86.

[0087] FIG. 10 is an explanatory diagram showing an example of a state in which the protrusion is engaged with the fixed guide in the Peltier element unit according to the embodiment, and shows that the axial separation distance between the inner flange of the main body and the outer flange of the ring fastener is X1.

[0088] As an example, as shown in Figure 10, when the protrusion piece 132 sliding from the introduction surface 97 is positioned by the fixed guide 86 and the first retaining surface 88a located between the first regulating surface 87a and the second regulating surface 87b, the inner flange 83 and the outer flange 131 are fixed at a position separated by the largest separation distance X1 (e.g., 3 mm).

[0089] In this way, the Peltier element unit 80 can change the distance in the axial direction AX between the inner flange 83 of the main body 82 and the ring fastener 130. Therefore, when the Peltier element unit 80 is attached by sandwiching the peripheral portion of the fabric 102 or the like between the inner flange 83 and the sandwiching surface 133 of the outer flange 131, as in the body temperature regulating clothing 100 described below, a wide range of thicknesses of the gripped portion, such as the peripheral portion 122, that can be sandwiched can be accommodated.

[0090] <Overview of Body Temperature Regulating Clothing 100> Next, an overview of the body temperature regulating garment 100 will be described with reference to Figs. 11 to 18. Fig. 11 is a front view of the outer surface of the body temperature regulating garment according to an embodiment when an air blower and a Peltier element unit are attached, viewed from the front body side. Fig. 12 is a back view of the body temperature regulating garment according to an embodiment when an air blower and a Peltier element unit are attached, viewed from the back body side. Fig. 13 is a front view of the inside of the body temperature regulating garment according to an embodiment when an air blower and a Peltier element unit are attached, viewed from the front body side. Fig. 14 is an enlarged front view of a main part of the collar of the body temperature regulating garment shown in Fig. 13. Fig. 14 is a back view of the body temperature regulating garment according to an embodiment when an air blower and a Peltier element unit are not attached, viewed from the back body side. Fig. 15 is an enlarged front view of a main part of the collar of the body temperature regulating garment according to an embodiment when an air blower and a Peltier element unit are not attached.

[0091] In the body temperature regulating clothing 100 shown in Fig. 11, the left-right direction is the Y-axis direction and the up-down direction is the X-axis direction, and the directions defined in Fig. 11 also apply to Figs. 12 to 18. In the body temperature regulating clothing 100 shown in Fig. 17, the left-right direction is the Z-axis direction and the up-down direction is the X-axis direction, and the directions defined in Fig. 18 and Figs. 25 to 28 also apply.

[0092] As shown in FIGS. 11 and 12, the body temperature regulating garment 100 is formed by attaching the air blower 1 according to the present embodiment described above to a fabric 102 constituting a vest, as an example, as a fan unit for blowing air, and the Peltier element unit 80 according to the present embodiment described above as a Peltier element unit for regulating the body temperature of the wearer HM. The body temperature regulating garment 100 is configured so that the air blower 1 can blow air AR toward the body BS of the wearer HM. The body temperature regulating garment 100 is also configured so that the heat transfer surface 81 of the Peltier element unit 80 can be brought into direct contact with the body BS, either directly or indirectly via underwear or the like, to cool or warm the nape of the neck of the wearer HM. The form of the fabric 102 is not limited to a vest, and various modifications are possible. For example, the body temperature regulating garment 100 corresponds to the body temperature regulating garment according to the present disclosure.

[0093] The body temperature regulating clothing 100 is used by people who particularly need cool air, such as workers who work outdoors in extreme heat, workers who work in indoor, humid environments while wearing work clothes, and people who engage in recreational activities, sports, or watching games under the scorching sun.

[0094] The body temperature regulating garment 100 comprises a garment main body 101, an air blower 1, a Peltier element unit 80, an air blowing operation unit 200, a temperature adjustment operation unit 300, etc. In this embodiment, as an example, there is one air blowing operation unit 200. In this embodiment, as an example, there is one temperature adjustment operation unit 300. In each figure, illustration of electrical wiring for the air blower 1, electrical wiring for the Peltier element unit 80, and power supplies is omitted.

[0095] <About the clothing body 101> Next, the garment body 101 will be described with reference to FIGS. 11 to 18. As shown in FIGS. 11 to 13 and 15, the garment body 101 is composed of a front body 103, a back body 104, a collar 105, a gusset air guide 112 disposed at a portion of the upper end of the collar 105, armholes 141 through which the wearer's arms pass when wearing the garment, and a hem 146. The garment body 101 is formed in the form of a vest (workwear without cuffs). However, this body temperature regulating garment may also be workwear with long or short sleeves. For example, the front body 103 corresponds to the front body of the present disclosure, and the back body 104 corresponds to the back body of the present disclosure.

[0096] The collar 105 forms a neckline at its upper part, where the wearer's neck will be positioned when worn. The armholes 141 have a left cuff 141A through which the wearer's HM's left arm is passed when worn, and a right cuff 141B through which the wearer's HM's right arm is passed when worn.

[0097] The garment body 101 has a fabric 102 formed into a vest shape by an outer fabric 102A and an inner fabric 102B. Both the outer fabric 102A and the inner fabric 102B are made of synthetic resin fibers with excellent heat resistance, strength resistance, and transpiration properties, such as nylon or polyester. However, this is not limited to this, and both the outer fabric 102A and the inner fabric 102B may be made of leather.

[0098] As shown in Fig. 11, the front body 103 of the garment body 101 is provided with a storage compartment 142, which may be a pocket. The storage compartment 142 includes a first storage compartment 142A located on the left chest of the garment body 101 and a second storage compartment 142B located on the right chest of the garment body 101. The storage compartment 142 further includes a third storage compartment 142C located on the left flank of the garment body 101 and a fourth storage compartment 142D located on the right flank of the garment body 101. The storage compartment 142 has an internal space between the front fabric 102A and a storage fabric sewn to the back fabric 102B. This allows, for example, electrical wiring for the air blower 1, electrical wiring for the Peltier element unit 80, and a power source to be inserted and removed from the storage compartment 142.

[0099] The armholes 141 (141A, 141B) according to this embodiment are provided with elastic annular members such as rubber, and the tightness of the annular members makes it difficult for air to escape from the armholes 141 (141A, 141B). This prevents air sent into the garment body 101 by the air blower 1 from escaping from the armholes 141 (141A, 141B), and allows the air to be largely released from the collar 105. However, this is not limiting. For example, the armholes 141 (141A, 141B) may be configured to allow air to be easily released.

[0100] The body temperature regulating garment 100 is configured so that when the fastener 143 on the front body 103 is opened, the entire back side of the back body 104 of the garment body 101 can be seen from the front body 103 side, as shown in Figure 13.

[0101] 12, 13, and 15, attachment portions 120 to which the air blower 1 can be attached are provided at one each on the left and right sides of the waist region WS of the body temperature regulating garment 100. However, this is not limited to this, and for example, attachment portions 120 may be provided at two locations on the abdomen of the front body piece 103. Also, for example, attachment portions 120 may be provided at two locations on the back of the back body piece 104 of the body temperature regulating garment 100.

[0102] As shown in Figures 12, 13, and 15, the attachment part 120 has an attachment part insertion hole 121 formed in the attachment part 120 and a peripheral edge part 122 around the attachment part insertion hole 121. The attachment part 120 is sewn onto the back fabric 102B. The attachment part insertion hole 121 is a hole for detachably attaching the air blower 1. The attachment part 120 is made of a material (e.g., leather) that is more rigid than the back fabric 102B and is also made of fabric that does not allow air to pass through. The attachment part 120 may also be made of fabric such as rubber or resin.

[0103] As shown in Figures 12, 13, and 15, an ice pack storage compartment 144 for storing an ice pack is sewn to one location on the back region BC of the back fabric 102B of the back body 104 of the body temperature regulating garment 100. The ice pack storage compartment 144 is made of a mesh-structured fabric with gaps formed by weaving or knitting synthetic resin fibers, such as nylon or polyester, that have excellent heat resistance, strength resistance, and transpiration properties. An internal space is formed between the fabric of the ice pack storage compartment 144 and the back fabric 102B. This allows the ice pack to be inserted and removed from the ice pack storage compartment 144. A hook-and-loop fastener 145 is sewn to the top end of the ice pack storage compartment 144. The hook and loop fastener 145 engages with a hook and loop fastener sewn to the inner fabric 102B, thereby preventing the cold insulation material stored in the cold insulation material storage section 144 from flying out.

[0104] By storing a cooling agent in the cooling material storage section 144, the back BC of the wearer HM can be cooled, and the air sent to the inside of the clothing body 101 by the air blower 1 can also be cooled.

[0105] As shown in FIG. 11, hem opening 146 is provided with two hem adjustment members 147 that allow the length of the hem to be adjusted. The hem adjustment members 147 are elastic ring-shaped members such as rubber. By adjusting the length of the hem using hem adjustment members 147, it is possible to make it difficult for air to escape from hem opening 146. This prevents the air sent into the garment body 101 by the air blower 1 from escaping from hem opening 146, and allows the air to be expelled more from the collar 105. However, this is not limiting. For example, the hem opening 146 may be configured to allow air to be easily expelled.

[0106] <About Collar 105> Next, the collar 105 will be described with reference to Figures 11 to 18. Figure 17 is a cross-sectional view taken along the line DD in Figure 15. Figure 18 is a cross-sectional view taken along the lines EE and FF in Figure 15.

[0107] As shown in FIGS. 11 to 18, collar 105 is composed of outer collar 106 and inner collar 107, which is located inside outer collar 106, i.e., on one side in the Y-axis direction (left side in FIGS. 17 and 18). Outer collar 106 is composed of outer collar fabric 106A, which blocks ventilation. Specifically, outer collar fabric 106A has no gaps that allow air to pass from one side of outer collar fabric 106A to the other, preventing air from passing from one side of outer collar fabric 106A to the other. Outer collar fabric 106A is composed of synthetic resin fibers, such as nylon or polyester, that offer excellent heat resistance, strength, and flexibility. For example, collar 105 corresponds to a collar according to the present disclosure; outer collar 106 corresponds to an outer collar according to the present disclosure; and inner collar 107 corresponds to an inner collar according to the present disclosure. For example, outer collar fabric 106A corresponds to the outer collar fabric according to the present disclosure.

[0108] 14 to 16, the inner collar 107 is composed of an adjustment unit 108 that changes and adjusts the position of the heat transfer surface 81 of the Peltier element unit 80 with respect to the circumferential direction LD around the person's neck, and an attachment unit 109 to which the Peltier element unit 80 can be attached. In the body temperature regulating garment 100 according to this embodiment, two Peltier element units 80 (a first Peltier element unit 80A and a second Peltier element unit 80B) are attached to the attachment units 109 at two locations on the inner collar 107 of the garment body 101. For example, the circumferential direction LD corresponds to the circumferential direction according to the present disclosure, and for example, the adjustment unit 108 corresponds to the adjustment unit according to the present disclosure.

[0109] 14 and 16, the adjustment portion 108 is rectangular and made of an adjustment fabric 108F that is stretchable in the circumferential direction LD. The adjustment fabric 108F is a stretchable material, i.e., a material that has elasticity, and is made of, for example, a material that contains nylon, polyester, or the like, as an elastic material such as rubber.

[0110] 14 and 16, the enlarged front views of the collar of the body temperature regulating garment show that inner collar 107 has first adjustment section 108A on the right side of first attachment section 109A, i.e., at right end 105A of inner collar 107. Also, as shown in the enlarged front views of the collar of the body temperature regulating garment shown in FIGS. 14 and 16, inner collar 107 has second adjustment section 108B between first attachment section 109A and second attachment section 109B. Also, as shown in the enlarged front views of the collar of the body temperature regulating garment shown in FIGS. 14 and 16, inner collar 107 has third adjustment section 108C on the left side of second attachment section 109B, i.e., at left end 105B of inner collar 107.

[0111] 14 and 16, the first adjustment unit 108A is an adjustment unit that adjusts the position of the heat transfer surface 81 of the first Peltier element unit 80A with respect to the circumferential direction LD around the person's neck by varying it. As shown in Fig. 14 and 16, the second adjustment unit 108B is an adjustment unit that adjusts the position of the heat transfer surface 81 of the first Peltier element unit 80A and the position of the heat transfer surface 81 of the second Peltier element unit 80B with respect to the circumferential direction LD around the person's neck by varying it. The third adjustment unit 108C is an adjustment unit that adjusts the position of the heat transfer surface 81 of the second Peltier element unit 80B with respect to the circumferential direction LD around the person's neck by varying it.

[0112] As shown in FIGS. 14 to 16, attachment portions 109 are provided in two locations on inner collar 107. Specifically, first attachment portion 109A is sewn onto first adjustment portion 108A and second adjustment portion 108B, and is provided between first adjustment portion 108A and second adjustment portion 108B. Second attachment portion 109B is sewn onto second adjustment portion 108B and third adjustment portion 108C, and is provided between second adjustment portion 108B and third adjustment portion 108C. As shown in FIGS. 14 to 16, attachment portion 109 has attachment portion insertion hole 123 formed in attachment portion 109 and attachment portion periphery 124 around attachment portion insertion hole 123.

[0113] As shown in Figures 14 and 16, on the inner collar 107, the first attachment section 109A extends further toward the fabric 102 in the X-axis direction than the sewn-together points of the first and second adjustment sections 108A and 108B, i.e., to one side in the X-axis direction (the lower side in Figures 14 and 16). This is to ensure the necessary space for attaching the first Peltier element unit 80A to the first attachment section 109A. Also, as shown in Figures 14 and 16, on the inner collar 107, the second attachment section 109B extends further toward the fabric 102 in the X-axis direction than the sewn-together points of the second and third adjustment sections 108B and 108C, i.e., to one side in the X-axis direction (the lower side in Figures 14 and 16). This is to ensure the necessary space for attaching the second Peltier element unit 80B to the second attachment section 109B.

[0114] As shown in FIGS. 14 and 16 , the attachment part 109 is formed by laminating a first attachment fabric 110, which is a mesh fabric, and a second attachment fabric 111, which blocks ventilation. This prevents wind flowing in from the first attachment fabric 110 side from escaping from the second attachment fabric 111 side. The first attachment fabric 110 is a fabric that has gaps that allow wind to pass from one side of the first attachment fabric 110 to the other. The first attachment fabric 110 has a mesh structure with gaps formed by weaving or knitting synthetic resin fibers, such as nylon and polyester, which have excellent heat resistance, strength, transpiration, and flexibility. On the other hand, the second attachment fabric 111 is a fabric that does not have gaps that allow wind to pass from one side of the second attachment fabric 111 to the other, and therefore does not allow wind to pass from one side of the second attachment fabric 111 to the other. The second wearing fabric 111 is made of synthetic resin fibers such as nylon, polyester, etc., which have excellent heat resistance, strength, and flexibility.

[0115] As shown in FIGS. 11 to 18 , a gusset air guide section 112 is disposed at the center IC of the collar 105 at the top end of the collar 105. The gusset air guide section 112 guides air sent into the main garment body 101 by the air blower 1 toward the top of the head HD of the wearer HM of the body temperature regulating garment 100. In this embodiment, the center IC of the collar 105 extends from the upper right edge of the first attachment section 109A to the upper left edge of the second attachment section 109B when viewing the inside of the body temperature regulating garment 100 shown in FIGS. 14 and 16 from the front body 103 side. The gusset air guide section 112 is made of a ventilation fabric 112A that allows air to pass through. Specifically, the ventilation fabric 112A has gaps that allow air to pass from one side of the ventilation fabric 112A to the other. The permissive fabric 112A is configured with a mesh structure in which gaps are formed by weaving or knitting synthetic resin fibers that have excellent heat resistance, strength, transpiration, and flexibility, such as nylon, polyester, etc. For example, the gusset air guide section 112 corresponds to the air guide section according to the present disclosure, and the permissive fabric 112A corresponds to the permissive fabric according to the present disclosure.

[0116] 17, in the state where the allowable fabric 112A is folded toward the outer collar 106 and inner collar 107, i.e., to one side in the X-axis direction (the lower side in FIGS. 17 and 18), the gusset air guide section 112 has one end 112Aa of the allowable fabric 112A sewn and fixed to the upper end 106Aa of the outer collar fabric 106A, and the other end 112Ab of the allowable fabric 112A sewn and fixed to the upper end 108Fa of the adjustment fabric 108F. For example, one end 112Aa of the allowable fabric 112A corresponds to one end of the allowable fabric according to the present disclosure, and the other end 112Ab of the allowable fabric 112A corresponds to the other end of the allowable fabric according to the present disclosure.

[0117] Furthermore, as shown in Figure 18, the gusset air guide section 112 is formed by folding the allowable fabric 112A toward the outer collar 106 and inner collar 107, i.e., to one side in the X-axis direction (the lower side in Figure 20), with one end 112Aa of the allowable fabric 112A sewn and fixed to the upper end 106Aa of the outer collar fabric 106A, and the other end 112Ab of the allowable fabric 112A sewn and fixed to the upper end 110A of the first attachment fabric 110 and the upper end 111A of the second attachment fabric 111.

[0118] 17 and 18, the crotch-side air guide passage 113 is formed in the crotch air guide section 112. The crotch-side air guide passage 113 is a flow path for circulating the air sent into the garment body 101 by the air blower 1 and directing the air to the top of the head HD of the wearer HM. For example, the crotch-side air guide passage 113 corresponds to the air guide passage according to the present disclosure.

[0119] As shown in Figure 17, when the gusset air guide portion 112 is folded over the opening fabric 112A towards the outer collar 106 and inner collar 107 and sewn and fixed to the collar 105, it protrudes from the uppermost end 106Am of the outer collar fabric 106A and the uppermost end 108Fm of the adjustment fabric 108F. Also, as shown in Figure 25, when the gusset air guide portion 112 is folded over the opening fabric 112A towards the outer collar 106 and inner collar 107 and sewn and fixed to the collar 105, it protrudes from the uppermost end 106Am of the outer collar fabric 106A, the uppermost end 110Am of the first attachment fabric 110, and the uppermost end 111Am of the second attachment fabric 111.

[0120] As shown in Figures 11 to 18, when the body temperature regulating garment 100 is viewed from the front and back, the crotch air guide sections 112 have a semicircular shape and protrude from the outer collar 106 and inner collar 107 to one side in the X-axis direction (upper side in Figures 14 and 16). Furthermore, when the body temperature regulating garment 100 is worn by a person, the crotch air guide sections 112 protrude from the outer collar 106 and inner collar 107 toward the back of the person's head NK. The crotch air guide sections 112 have the function of assisting in guiding air sent by the air blower 1 to the inside of the garment body 101 toward the head of the wearer HM.

[0121] 17 and 18, by folding the allowable fabric 112A toward the outer collar 106 and inner collar 107 and then sewing and securing the allowable fabric 112A to the outer collar 106 and inner collar 107, a collar-side air guide channel 114 is formed between the outer collar 106 and inner collar 107. This collar-side air guide channel 114 is a flow path that guides the air flowing in from the collar-side inlet 115 to the crotch-side air guide channel 113 for circulation. For example, the collar-side air guide channel 114 corresponds to the collar-side air guide channel according to the present disclosure.

[0122] As shown in Figures 17 and 18, the bottom end 106Ab of the outer collar fabric 106A is sewn and fixed to the top end 102u of the fabric 102. As shown in Figures 16 to 17, the bottom end 108Fb of the adjustable fabric 108F constituting the first adjustable portion 108A is not sewn and fixed to the fabric 102, except for the right end portion (right side in Figure 16). As shown in Figures 16 to 17, the bottom end 108Fb of the adjustable fabric 108F constituting the second adjustable portion 108B is not sewn and fixed to the fabric 102. As shown in Figures 16 to 17, the bottom end 108Fb of the adjustable fabric 108F constituting the third adjustable portion 108C is not sewn and fixed to the fabric 102, except for the left end portion (left side in Figure 16). 16 and 18, the lower end 110Ab of the first attachment fabric 110 and the lower end 111Ab of the second attachment fabric 111 that make up the attachment part 109 (first attachment part 109A, second attachment part 109B) are not sewn and fixed to the fabric 102. As a result, as shown in Figs. 16 to 18, a collar-side inlet 115 is formed to allow the air sent by the air blower 1 to the inside of the garment body 101 to circulate inside the collar-side air guide channel 114.

[0123] <Installation of the air blower 1> Next, the attachment of the air blower 1 to the body temperature regulating clothing 100 will be described with reference to Figures 19 and 20. Figure 19 is a schematic perspective view showing how to attach the air blower according to the embodiment to the fabric of the body temperature regulating clothing. Figure 20 is a cross-sectional view taken along the arrow BB in Figure 19, and is a schematic view showing the flow of air blowing through the guard in the space between the clothing and the body.

[0124] In the body temperature regulating garment 100, when the air blower 1 is attached to the fabric 102, as shown in Fig. 19, the intake-side peripheral wall 12 is inserted from the outside of the attachment portion 120 through the fabric insertion hole 102h drilled in the fabric 102 and the attachment portion insertion hole 121 drilled in the attachment portion 120. With the intake-side flange 11 of the intake-side case 10 abutting against the peripheral edge 122 formed by increasing the rigidity on the outer periphery of the fabric insertion hole 102h and the outer periphery of the attachment portion insertion hole 121, the air-blowing-side case 30 is positioned between the body BS of the wearer HM and the inside of the fabric 102, with the air-blowing-side flange 31 facing inward of the fabric 102.

[0125] The intake-side peripheral wall 12 of the intake-side case 10, which has been inserted through the clothing fabric insertion hole 102h and the attachment part insertion hole 121, is located between the body BS of the wearer HM and the inside of the clothing fabric 102. This intake-side peripheral wall 12 is inserted inside the blower-side peripheral wall 32 of the blower-side case 30. Then, by rotating the intake-side case 10 and the blower-side case 30 relatively around the axis C, the protrusion 20 of the intake-side case 10 and the fixed guide 40 of the blower-side case 30 are engaged, and the intake-side case 10 and the blower-side case 30 are assembled together.

[0126] Thus, the fabric 102 and the attachment portion 120 are sandwiched between the intake side flange 11 of the intake side case portion 10 and the blowing side flange 31 of the blowing side case portion 30, as shown in Figure 28, and the blowing device 1 is attached to the garment body 101 of the body temperature regulating garment 100.

[0127] In particular, in the case of the body temperature regulating garment 100 illustrated in Fig. 20, in which the air blower 1 is attached to the fabric 102 and blows air AR from the air blower 1 toward the body BS, the distance from the fabric 102 to which the air blower 1 is attached to the body BS behind it is only a few centimeters. When the air blower 1 is used under such conditions, the guard tip 3a of the guard 3 comes into contact with or is in close proximity to the body BS. As a result, the air mainly hits only the body-side contact area facing the propeller. In the internal space between the fabric and the body, especially near the guard tip, the airflow from the propeller and the airflow that changes direction after hitting the body-side contact area create vortices that adversely affect each other, resulting in turbulence. As a result, the air blown from the propeller stagnates around the guard, preventing it from reaching a wide area from the air blower to the surrounding area within the space between the fabric and the body.

[0128] However, in the air blower 1 according to this embodiment, as shown in Fig. 20 etc., the direction of the airflow AR sent out from the blades 61 is bent by the airflow direction adjusting member 50 in the gap 4 which forms the airflow path. Therefore, as shown in Fig. 20, even if the air blower 1 attached to the fabric 102 sends out the airflow AR into a narrow space formed only a few centimeters from the body BS, the airflow AR reaches a wide area from the air blower 1 to the surrounding area.

[0129] Moreover, as shown in FIG. 20 and other figures, the wind AR sent out from the blades 61 does not stagnate around the guard 3, but flows through the gaps 4 in the guard 3, around the blower 1 in the airflow region STw that is widely dispersed around the axis C. In addition, the wind AR sent out from the blades 61 is distributed widely over 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 of the body BS facing the blade main body 60, but also in surrounding regions away from the central region, improving the comfort of the wearer HM. Therefore, the blower 1 according to this embodiment has the excellent effect of being able to control the wind direction by the rotation of the blades 61 so that the sent wind AR circulates over a wider area on the downwind side FD of the blades 61.

[0130] <Installing the Peltier element unit 80> Next, how to attach the air blower 1 to the body temperature regulating clothing 100 will be described with reference to Figures 21 and 22. Figure 21 is an explanatory diagram showing a method for attaching the Peltier element unit to the body temperature regulating clothing. Figure 22 is a partial cross-sectional view of the Peltier element unit as seen from the arrow CC in Figure 12.

[0131] 21 and 22 , when the Peltier element unit 80 of the body temperature regulating garment 100 is attached to the attachment part 109, the main body part 82 is inserted from the outside of the attachment part 109 into an attachment part insertion hole 123 drilled in the attachment part 109. With the inner flange 83 of the main body part 82 abutting against an attachment part peripheral part 124 formed by increasing the rigidity on the outer periphery of the attachment part 109, the outer peripheral surface 82a of the main body part 82 and the ceiling part 91 are positioned between the outer collar 106 and the inner collar 107, i.e., within the collar-side air guide channel 114.

[0132] The inner flange 83, cylindrical portion 84, and heat transfer surface 81 (cooling surface 81A, heating surface 81B) of the main body portion 82 inserted through the attachment portion insertion hole 123 are located between the body BS of the wearer HM and the inner collar 107. This main body portion 82 is inserted inside the ring fastener 130. Then, by rotating the main body portion 82 and the ring fastener 130 relatively around the axis C, the protruding piece 20 of the ring fastener 130 and the fixed guide 86 of the main body portion 82 are engaged, and the main body portion 82 and the ring fastener 130 are assembled together.

[0133] Thus, as shown in Figure 22, the attachment portion 109 is sandwiched between the inner flange 83 of the main body portion 82 and the ring fastener 130, thereby attaching the Peltier element unit 80 to the clothing main body 101 of the body temperature regulating clothing 100.

[0134] In this embodiment, the first Peltier element unit 80A is attached to the first attachment part 109A constituting the inner collar 107. This allows the heat transfer surface 81 (cooling surface 81A or heating surface 81B) of the first Peltier element unit 80A to face and be in contact with the body side (left nape NFL) of the wearer HM of the body temperature adjusting garment 100 (see FIG. 29). The heat transfer surface 81 (cooling surface 81A or heating surface 81B) can be brought into contact with the left nape NFL of the wearer's neck directly or indirectly via underwear or the like, thereby cooling the left nape NFL of the wearer's neck.

[0135] In this embodiment, the second Peltier element unit 80B is attached to the second attachment portion 109B constituting the inner collar 107. This allows the heat transfer surface 81 (cooling surface 81A or heating surface 81B) of the second Peltier element unit 80B to face and come into contact with the body side (right nape NFR) of the wearer HM of the body temperature adjusting garment 100 (see FIG. 29). The heat transfer surface 81 (cooling surface 81A or heating surface 81B) can be brought into contact with the right nape NFR of the neck of the wearer HM directly or indirectly via underwear or the like, thereby cooling the right nape NFR of the neck of the wearer.

[0136] <Regarding the adjustment unit 108 and the attachment unit 109> Fig. 23 is a schematic diagram 1 showing a cross section of a main part of body temperature regulating clothing equipped with a Peltier element unit when worn by a person. Fig. 24 is a schematic diagram 2 showing a cross section of a main part of body temperature regulating clothing equipped with a Peltier element unit when worn by a person. In Figs. 23 and 24, the body temperature regulating clothing 100 has the line fastener 143 fastened to the neck, i.e., the uppermost end, and the heat transfer surface 81 of the Peltier element unit 80 attached to the inner collar 107 abuts against the nape NF of the neck. Fig. 23 shows a person with an average neck wearing body temperature regulating clothing equipped with a Peltier element unit, and Fig. 24 shows a person with a thicker neck than average wearing body temperature regulating clothing equipped with a Peltier element unit.

[0137] 23, when body temperature regulating clothing 100 is worn by a person with a normal neck size, first adjustment part 108A stretches as shown by arrow AW1 and second adjustment part 108B stretches as shown by arrow AW2 in accordance with the thickness of the person's neck N1. As a result, the heat transfer surface 81 of first Peltier element unit 80A attached to first attachment part 109A changes position to face the left nape NFL1 of the neck N1 in accordance with the thickness of the neck N1, and the contact position of heat transfer surface 81 can come into contact with the left nape NFL1 of the neck N1.

[0138] 23, when the body temperature regulating garment 100 is worn by a person with a normal neck size, the second adjustment part 108B stretches as shown by arrow AW2 and the third adjustment part 108C stretches as shown by arrow AW3 in accordance with the thickness of the person's neck N1. As a result, the heat transfer surface 81 of the second Peltier element unit 80B attached to the second attachment part 109B changes position to face the right nape NFR1 of the neck N1 in accordance with the thickness of the neck N1, and the contact position of the heat transfer surface 81 can come into contact with the right nape NFR1 of the neck N1.

[0139] On the other hand, as shown in Fig. 24, when a person with a thicker neck than the average person wears the body temperature regulating garment 100, the first adjustment portion 108A stretches as shown by arrow AW4, which is thicker than arrow AW1 shown in Fig. 23, in accordance with the thickness of the person's neck N2, and the second adjustment portion 108B stretches as shown by arrow AW5, which is thicker than arrow AW2 shown in Fig. 23. As a result, in accordance with the thickness of the neck N2, which is thicker than the neck N1, the heat transfer surface 81 of the first Peltier element unit 80A attached to the first attachment portion 109A moves to face the left nape NFL2 of the neck N2, and the contact position of the heat transfer surface 81 can come into contact with the left nape NFL2 of the neck N2.

[0140] As shown in Fig. 24, when a person with a thicker neck than the average person wears the body temperature regulating garment 100, the second adjustment portion 108B stretches as shown by the arrow AW5, which is thicker than the arrow AW2 shown in Fig. 23, in accordance with the thickness of the person's neck N2, and the third adjustment portion 108C stretches as shown by the arrow AW6, which is thicker than the arrow AW3 shown in Fig. 23. As a result, in accordance with the thickness of the neck N2, which is thicker than the neck N1, the heat transfer surface 81 of the second Peltier element unit 80B attached to the second attachment portion 109B moves to face the right nape NFR2 of the neck N2, and the contact position of the heat transfer surface 81 can come into contact with the right nape NFR2 of the neck N2.

[0141] In a body temperature regulator that regulates temperature using a heat transfer surface that comes into contact with a person's neck, such as that disclosed in Patent Document 1, it is difficult to adjust the position of the heat transfer surface that comes into contact with the person's neck in accordance with the physique and movements of the person wearing the body temperature regulator, and therefore it is not possible to efficiently regulate the temperature of the person's body. However, in the body temperature regulating garment 100 of this embodiment, as shown in the schematic diagrams of Figures 23 and 24, the adjustment parts 108 (108A, 108B, 108C) stretch in accordance with the physique (e.g., neck size) of the wearer HM of the body temperature regulating garment 100, thereby making it possible to change and adjust the position at which the heat transfer surface 81 of the Peltier element unit 80 comes into contact with the neck N of the wearer HM. Furthermore, the position at which the heat transfer surface 81 of the Peltier element unit 80 contacts the neck N of the wearer HM can be varied and adjusted by the expansion and contraction of the adjustment parts 108 (108A, 108B, 108C) in accordance with the movements (e.g., neck movement) of the wearer HM of the body temperature regulating garment 100. This avoids the situation where the heat transfer surface 81 of the Peltier element unit 80 cannot contact the desired position (e.g., left nape of the neck NFL, right nape of the neck NFR) due to the physique (e.g., neck thickness, neck movement) of the wearer HM of the body temperature regulating garment 100, and allows for efficient temperature regulation of the neck in contact with the heat transfer surface 81.

[0142] <About the crotch air guide section 112 and collar side air guide duct 114> First, a case where the air blower 1 is not blowing air into the garment body 101 will be described with reference to Figures 25 and 26. Figure 25 is an explanatory diagram 1 illustrating a state where the air blown by the air blower is not flowing through the crotch-side air guide passage and the collar-side air guide passage. Figure 26 is an explanatory diagram 2 illustrating a state where the air blown by the air blower is not flowing through the crotch-side air guide passage and the collar-side air guide passage.

[0143] First, a state in which the air sent into the garment body 101 by the air blower 1 does not flow through the crotch-side air guide passage 113 and the collar-side air guide passage 114 will be described with reference to FIGS.

[0144] As shown in Figures 25 and 26, when the air sent into the garment main body 101 by the air blower 1 does not flow through the collar-side air guide passage 114, the outer collar 106 does not inflate due to the air blowing outward from the outer collar 106, i.e., to one side in the Z-axis direction (the right side in Figures 25 and 26). As shown in Figure 25, when the air sent into the garment main body 101 by the air blower 1 does not flow through the collar-side air guide passage 114, the adjustment portion 108 does not inflate due to the air blowing outward from the adjustment portion 108, i.e., to one side in the Z-axis direction (the left side in Figure 25). As shown in Figure 26, when the air sent into the garment main body 101 by the air blower 1 does not flow through the collar-side air guide passage 114, the attachment portion 109 does not inflate due to the air blowing outward from the attachment portion 109, i.e., to one side in the Z-axis direction (the left side in Figure 26). As shown in Figures 25 and 26, the outer collar 106 and inner collar 107 are not inflated, so the outer collar 106 and inner collar 107 are less likely to come into contact with the neck of the wearer HM of the body temperature regulating garment 100, making the wearer HM less likely to feel uncomfortable.

[0145] 25 and 26, when the air sent into the garment body 101 by the air blower 1 is not flowing through the crotch-side air guide passages 113, the crotch air guide sections 112 are not inflated by the air toward the outside of the crotch air guide sections 112, i.e., toward both sides in the Z-axis direction (the left and right sides in FIGS. 25 and 26). Because the crotch air guide sections 112 arranged at the top end of the collar 105 are not inflated, it is possible to avoid the crotch air guide sections 112 coming into contact with the body of the wearer HM of the body temperature regulating garment 100 and causing discomfort.

[0146] Next, using Figures 27 and 28, we will explain how the air sent into the garment body 101 by the air blower 1 flows through the groin-side air guide passage 113 and the collar-side air guide passage 114. Figure 27 is an explanatory diagram 1 for explaining how the air blown by the air blower flows through the groin-side air guide passage and the collar-side air guide passage. Figure 28 is an explanatory diagram 2 for explaining how the air blown by the air blower flows through the groin-side air guide passage and the collar-side air guide passage.

[0147] As shown in Fig. 27, when air sent into the interior of the garment main body 101 by the air blower 1 flows through collar-side air guide passage 114, the air causes outer collar 106 to bulge outward from outer collar 106, i.e., to one side in the Z-axis direction (the right side in Fig. 27). As shown in Fig. 27, when air sent into the interior of garment main body 101 by the air blower 1 flows through collar-side air guide passage 114, the air causes adjustment portion 108 to bulge outward from adjustment portion 108, i.e., to one side in the Z-axis direction (the left side in Fig. 27). As a result, as shown in Fig. 27, collar-side air guide passage 114, which is formed between inner collar 107 consisting of outer collar 106 and adjustment portion 108, is larger than collar-side air guide passage 114 shown in Fig. 27. As a result, a large amount of air flowing through collar-side air guide passage 114 shown in Fig. 27 can be guided to crotch-side air guide passage 113.

[0148] As shown in Fig. 27, when air sent into the garment main body 101 by the air blower 1 flows through the crotch-side air guide passages 113, the crotch air guide section 112 is inflated by the air toward the outside of the crotch air guide section 112, i.e., toward both sides in the Z-axis direction (left and right sides in Fig. 27). As a result, the crotch-side air guide passages 113 formed within the crotch air guide section 112 are larger than the crotch-side air guide passages 113 shown in Fig. 25. Therefore, a large amount of air flowing through the crotch-side air guide passages 113 shown in Fig. 27 can pass through the permeable fabric 112A and flow over a wide area toward the head of the wearer HM of the body temperature regulating garment 100.

[0149] As shown in Fig. 28, when air sent into the interior of the garment body 101 by the air blower 1 flows through the collar-side air guide passage 114, the air causes the outer collar 106 to bulge outward from the outer collar 106, i.e., to one side in the Z-axis direction (the right side in Fig. 28). As a result, as shown in Fig. 28, the collar-side air guide passage 114 formed between the outer collar 106 and the inner collar 107 consisting of the attachment part 109 is larger than the collar-side air guide passage 114 shown in Fig. 28. This allows a large amount of air flowing through the collar-side air guide passage 114 shown in Fig. 28 to be guided to the crotch-side air guide passage 113.

[0150] 28, a portion AR1 of the air AR sent into the garment body 101 by the air blower 1 flows in through the intake holes 85a of the Peltier element unit 80, where it comes into contact with the heat dissipation fins 93a and exchanges heat with the Peltier elements PE. The heat-exchanged air is then expelled from the exhaust holes 92 as exhaust air ER by the rotation of the propeller 95 of the heat exhaust device 94. The exhaust air ER is then merged with a portion AR2 of the air AR flowing through the collar-side air guide path 114 to form combined air FR, which flows into the crotch-side air guide path 113.

[0151] As shown in Fig. 28, when air AR sent into the garment main body 101 by the air blower 1 flows through the crotch-side air guide passage 113, the air AR causes the crotch air guide section 112 to expand outward from the crotch air guide section 112, i.e., toward both sides in the Y-axis direction (left and right sides in Fig. 28). As a result, the crotch-side air guide passage 113 formed within the crotch air guide section 112 is larger than the crotch-side air guide passage 113 shown in Fig. 26. Therefore, as shown in Fig. 28, the combined air FR, which is the combination of the exhaust air ER and the large amount of air AR flowing through the collar-side air guide passage 114, can pass through the permeable fabric 112A and flow over a wide area toward the head of the wearer HM of the body temperature regulating garment 100.

[0152] <About the flow of air sent out by the blower 1> Next, the flow of air blown out by the air blower 1 attached to the body temperature regulating clothing 100 will be described with reference to Fig. 29. Fig. 29 is an explanatory diagram for explaining the flow of air blown out by the air blower attached to the body temperature regulating clothing shown in Fig. 11.

[0153] As shown in Fig. 29, air blowers 1 attached to two locations on the waist region WS of the back body 104 of the body temperature regulating garment 100 blow air AR from the outside of the garment body 101 to the inside of the garment body 101. Then, as shown in Fig. 29, the air AR blown into the garment body 101 by the air blowers 1 circulates over a wide area inside the garment body 101 and flows toward the collar 105 of the body temperature regulating garment 100. Note that the air AR blown into the garment body 101 by the air blowers 1 evaporates sweat from the wearer HM's body as it circulates inside the garment body 101, thereby cooling the air AR and cooling the wearer HM's body with the heat of vaporization generated during evaporation.

[0154] 28-29, a portion of the air AR sent by the air blower 1 from the outside of the garment main body 101 to the inside of the garment main body 101 flows from the collar-side inlet 115 into the collar-side air guide channel 114. Subsequently, a portion of the air AR guided to the crotch-side air guide channel 113 via the collar-side air guide channel 114 merges with the exhaust air ER and, as combined air FR, passes through the allowable fabric 112A and flows toward the neck of the wearer HM of the body temperature regulating garment 100. Also, as shown in FIG. 29, as shown in FIGS. 27 and 29, a portion of the air AR guided to the crotch-side air guide channel 113 via the collar-side air guide channel 114 passes through the allowable fabric 112A and flows toward the back of the head NK of the wearer HM of the body temperature regulating garment 100, thereby cooling the back of the head NK of the wearer HM. Furthermore, as shown in FIG. 29, part of the wind AR blowing toward the back of the head NK may flow toward the top of the head HD of the wearer HM of the body temperature regulating garment 100.

[0155] <About the air blower operation unit> The air blow operation unit has an air blow control unit, an air blow operation unit, an air blow display unit, etc. In the air blow operation unit, the air blow operation unit and the air blow display unit are electrically connected to the air blow control unit.

[0156] The air blowing operation unit is configured in a manner that enables operation to control the on / off switching operation of power supply to the motor of the drive unit 70 by lightly pressing a push-down section on the top surface of the air blowing operation unit with a finger based on a predetermined operation mode. The air blowing display unit is a display section on the top surface of the air blowing operation unit, and is configured in a manner that allows it to emit white light.

[0157] <About the temperature control unit> The temperature adjustment operation unit has a temperature adjustment control section, a temperature adjustment operation section, a temperature adjustment display section, etc. In the temperature adjustment operation unit, the temperature adjustment operation section and the temperature adjustment display section are electrically connected to the temperature adjustment control section.

[0158] The temperature adjustment operation unit is configured in a manner that enables operation to control the on / off switching operation of power supply to the Peltier element PE for the first and second Peltier element units 80A, 80B by pressing a press-down portion on the top surface of the temperature adjustment operation unit. Furthermore, the temperature adjustment operation unit is configured in a manner that enables operation to control the on / off switching operation of power supply to a motor (not shown) that rotates the heat dissipation device 94 by pressing a press-down portion on the top surface of the temperature adjustment operation unit. The temperature adjustment display unit is a display portion on the top surface of the temperature adjustment operation unit that is configured in a manner that enables light to be selectively emitted in a plurality of colors.

[0159] If the temperature adjustment control unit has a control for reversing the direction of the direct current supplied to the Peltier element PE from the necessary power source (battery), the temperature adjustment operation unit lightly presses a depression on the top surface of the temperature adjustment operation unit based on a predetermined operation mode different from the operation of switching on / off the current, thereby switching the polarity of the current flowing to the first and second Peltier element units 80A and 80B.

[0160] In the Peltier element unit 80, when the direction of the DC current supplied to the Peltier element PE is reversed, the functions of one side and the other side are reversed. Therefore, if the temperature adjustment control unit is configured to be able to reverse the polarity of the current supplied to the Peltier element PE, the heat transfer surface 81 can be selectively changed by the temperature adjustment control unit between a cooling surface 81A cooled by heat absorption and a heating surface 81B heated by heat generation. As a result, the cooling surface 81A and the heating surface 81B are interchangeable on the heat transfer surface 81. Note that if the temperature adjustment control unit does not have the function of switching the direction of the current to the Peltier element PE, the heat transfer surface 81 is either the cooling surface 81A or the heating surface 81B.

[0161] Next, the functions and effects of the body temperature regulating clothing according to this embodiment will be described.

[0162] The body temperature regulating garment 100 of this embodiment has a Peltier element PE and one or more Peltier element units 80 each having a heat transfer surface 81 that cools or heats using the Peltier element PE can be attached to the collar 105, and the garment body 101 is composed of at least a front body 103, a back body 104, and a collar 105, and the collar 105 is provided with an attachment section 109 to which the Peltier element unit 80 can be attached, and an adjustment section 108 that changes and adjusts the position of the heat transfer surface 81 in the circumferential direction LD around the person's neck, and the adjustment section 108 is made of a stretchable material.

[0163] In the body temperature regulating garment 100 according to this embodiment, the adjustment section 108 of the inner collar 107 is made of a stretchable material, and examples of elastic materials such as rubber include nylon and polyester. The adjustment section 108 adjusts the position of the heat transfer surface 81 of the Peltier element unit 80 attached to the attachment section 109 of the inner collar 107 relative to the circumferential direction LD around the neck of the wearer HM, depending on the build and movement of the wearer HM wearing the body temperature regulating garment 100. This allows the adjustment section 108 to stretch to accommodate various neck thicknesses of the wearer HM, and the contact position of the heat transfer surface 81 can be adjusted relative to the circumferential direction LD around the neck of the wearer HM, thereby efficiently cooling or warming the left nape NFL and the right nape NFR of the neck, as shown in FIGS. 23 and 24 . Furthermore, for example, even if the adjustment part 108 stretches in response to the movement of the neck N of the wearer HM, the position at which the heat transfer surface 81 comes into contact can be varied and adjusted relative to the circumferential direction LD around the neck of the wearer HM, thereby efficiently cooling or warming the left neck region NFL and the right neck region NFR.

[0164] In addition, the body temperature regulating clothing 100 of this embodiment has an attachment section 109 which includes a first attachment section 109A to which the first Peltier element unit 80A can be attached, and a second attachment section 109B to which the second Peltier element unit 80B can be attached, and a second adjustment section 108B is provided between the first attachment section 109A and the second attachment section 109B.

[0165] According to the body temperature regulating garment 100 of this embodiment, the contact position between the heat transfer surfaces 81 of the first Peltier element unit 80A and the second Peltier element unit 80B is variably adjusted according to the neck thickness and neck movement of the wearer HM by stretching the second adjustment part 108B provided between the first attachment part 109A and the second attachment part 109B. This allows the heat transfer surfaces 81 to contact the left and right neck regions NFL and NFR of the neck to efficiently cool or warm the wearer HM regardless of the neck thickness or neck movement.

[0166] Furthermore, in the body temperature regulating garment 100 according to this embodiment, an adjustment portion 108 is provided on at least one of the left and right ends of the collar 105.

[0167] According to the body temperature regulating garment 100 of this embodiment, the contact position with the heat transfer surface 81 can be variably adjusted to accommodate the neck thickness and neck movement of the wearer HM by stretching the first adjustment part 108A and the third adjustment part 108B provided on the left and right ends of the collar 105. This allows the heat transfer surfaces 81 to contact the left and right neck regions NFL and NFR of the neck to efficiently cool or warm while adapting to the neck thickness and neck movement of various wearers HM.

[0168] In addition, in the body temperature regulating clothing 100 of this embodiment, a blower 1 that blows air from the outside of the clothing main body 101 into the inside of the clothing main body 101 can be attached to the body temperature regulating clothing 100, at least a portion of the upper end of the collar 105 is made of a permeable fabric 112A that allows ventilation, and a crotch air guide section 112 is arranged to guide the air sent into the clothing main body 101 by the blower 1 toward the head of the wearer HM of the body temperature regulating clothing 100, and the crotch air guide section 112 protrudes from the uppermost end of the collar 105.

[0169] In the body temperature regulating garment 100 according to this embodiment, air is blown from the outside of the garment body 101 into the inside of the garment body 101 by the air blower 1. As the air flows through the garment body 101, sweat from the upper body evaporates, and the heat of vaporization cools the upper body of the wearer HM. Then, the gusset air guide section 112, which is disposed in the central portion IC of the upper end of the collar 105 and extends beyond the top edge of the collar 105, and is made of ventilation-permitting fabric 112A, guides the air cooled by the heat of vaporization toward the head of the wearer HM wearing the body temperature regulating garment 100. Therefore, not only is the upper body of the wearer HM cooled by the heat of vaporization, but the air cooled by the heat of vaporization can also cool the head of the wearer HM, and the heat transfer surface 81 of the Peltier element unit 80 can also cool the neck, allowing the body temperature regulating garment 100 to be used effectively. Therefore, for example, when a person who is working outdoors in extreme heat, or who is particularly seeking cool air, wears the body temperature regulating clothing 100, the body can be efficiently cooled by the heat transfer surface 81 of the Peltier element unit 80 and the air blown by the blower 1.

[0170] Furthermore, in the body temperature regulating garment 100 of this embodiment, the collar 105 is composed of an outer collar 106 and an inner collar 107 provided inside the outer collar 106, and the inner collar 107 is provided with an attachment section 109 and an adjustment section 108. By fixing one end 112Aa of the allowable fabric 112A to at least a part of the upper end 106Aa of the outer collar 106 and fixing the other end 112Ab of the allowable fabric 112A to at least a part of the upper end of the inner collar 107 (upper end 108Fa of the adjustment fabric 108F, upper end 110A of the first attachment fabric 110, upper end 111A of the second attachment fabric 111), a crotch side air guide path 113 is formed within the crotch air guide section 112 through which the air sent into the interior of the garment body 101 by the air blower 1 circulates.

[0171] In the body temperature regulating garment 100 according to this embodiment, one end 112Aa of the allowable fabric 112A is fixed at a central portion OC of the top end 106Aa of the outer collar 106, and the other end 112Ab of the allowable fabric 112A is fixed at a central portion IC of the top end of the inner collar 107 (the top end 108Fa of the adjusting fabric 108F, the top end 110A of the first wearing fabric 110, and the top end 111A of the second wearing fabric 111). This allows air cooled by the heat of vaporization to circulate through the crotch-side air guide channel 113 formed in the crotch air guide section 112. This prevents the air cooled by the heat of vaporization from dispersing from the collar 105, allowing the air delivered to the head of the wearer HM to cool the head and the neck N of the wearer HM, which is in contact with the heat transfer surface 81.

[0172] In addition, in the body temperature regulating garment 100 of this embodiment, the outer collar 106 is made of outer collar fabric 106A that blocks ventilation, and a collar-side air guide path 114 is formed between the outer collar 106 and the inner collar 107 to guide the air sent into the garment body 101 by the air blower 1 to the crotch-side air guide path 113.

[0173] In the body temperature regulating garment 100 according to this embodiment, air sent into the garment body 101 by the air blower 1 flows in through the collar-side inlet 115 and circulates through collar-side air guide channels 114 formed in the outer collar 106 and inner collar 107. The air circulating through collar-side air guide channels 114 then flows into the crotch-side air guide channels 113 without being released from the outer collar fabric 106A to the outside of the garment body 101. This prevents air cooled by the heat of vaporization from escaping to the outside of the garment body 101, allowing the air to cool the head of the wearer HM and the neck N of the wearer HM, which is in contact with the heat transfer surface 81.

[0174] In addition, in the body temperature regulating clothing 100 of this embodiment, the Peltier element unit 80 comprises a main body portion 82 that houses the Peltier element PE, a heat exchange surface 93 opposite the heat transfer surface 81, an intake hole 85a that takes in air from the outside of the main body portion 82, and an exhaust hole 92 that exhausts the air that has been heat exchanged on the heat exchange surface 93, and when the Peltier element unit 80 is attached to the attachment portion 109, the exhaust hole 92 is arranged in the collar-side air guide duct 114.

[0175] According to the body temperature regulating garment 100 of this embodiment, air is taken in through the intake holes 85a of the main body 82 of the Peltier element unit 80 attached to the attachment part 109 of the inner collar 107, and the air that has exchanged heat on the heat exchange surface 93 is exhausted through the exhaust holes 92 into the collar-side air guide channel 114. As a result, the air exhausted from the exhaust holes 92 joins with the air sent into the garment main body 101 by the air blower 1 and is guided to the crotch-side air guide channel 113, and the head of the wearer HM can be cooled by the air guided from the crotch-side air guide channel 113.

[0176] Although the present disclosure has been described above based on the embodiments, the present disclosure is not limited to the above embodiments and can be appropriately modified and applied without departing from the spirit of the present disclosure. Of course, the configurations according to the above embodiments and the following modified examples may be appropriately combined. Technical features of the above embodiments and the following modified examples may be appropriately deleted unless they are described as essential in this specification.

[0177] Although the Peltier element unit 80 is attached to the inner collar 107 according to the above embodiment, the present invention is not limited to this. For example, the Peltier element unit may be attached to the outer collar .

[0178] Although the collar 105 according to the above embodiment is composed of outer collar fabric 106A and inner collar 107 fabric (adjustment fabric 108F, first attachment fabric 110, second attachment fabric 111), it is not limited to this. For example, collar 105 may be composed of a single piece of collar fabric, and attachment portion 109 and adjustment portion 108 may be provided on collar 105 composed of this single piece of collar fabric.

[0179] In the above embodiment, two attachment points 109 are provided on the inner collar 107. However, this is not limited to this. The number, placement position, and arrangement of attachment points on the inner collar 107 can be changed as appropriate depending on the specifications of the product, such as the intended use of the body temperature regulating garment (product) according to the present disclosure and the physique of the wearer.

[0180] In the above embodiment, the Peltier element unit 80 can be attached to the attachment portion 109 of the inner collar 107 so that the heat transfer surface 81 of the Peltier element unit 80 comes into contact with the nape of the neck of the wearer HM. However, this is not limited to this. For example, an attachment portion may be provided on the left or right end of the inner collar 107 so that the heat transfer surface 81 of the Peltier element unit 80 comes into contact with the neck of the wearer HM. This allows the heat transfer surface 81 of the Peltier element unit 80 attached to the attachment portion provided on the left or right end of the inner collar 107 to cool or warm the neck of the wearer HM.

[0181] In the above embodiment, adjustment elements 108 are provided in a total of three locations on inner collar 107. However, this is not limited to this. The number, placement position, and arrangement of adjustment elements on inner collar 107 can be changed as appropriate depending on the use of the body temperature regulating garment (product) according to the present disclosure, the physique of the wearer, and other product specifications.

[0182] In the above embodiment, the adjustment portion 108 is provided on both the right end 107A and the left end 107B of the inner collar 107. However, this is not limited to this. For example, the adjustment portion 108 may be provided on only one of the right end 107A and the left end 107B of the inner collar 107.

[0183] In the above embodiment, the crotch air guide section 112 has a semicircular shape that protrudes from the uppermost end 106Am of the outer collar fabric 106A of the outer collar 106 and the uppermost end of the inner collar 107 (the uppermost end 108Fm of the adjustment fabric 108F, the uppermost end 110Am of the first wearing fabric 110, and the uppermost end 111Am of the second wearing fabric 111) toward the head of the wearer HM when the body temperature regulating garment 100 is worn by a person (see FIGS. 11 to 16). However, the present invention is not limited to this. For example, the crotch air guide portion 112 may be semicircular and protrude outward from the uppermost end 106Am of the outer collar fabric 106A of the outer collar 106 and the uppermost end of the inner collar 107 (the uppermost end 108Fm of the adjustment fabric 108F, the uppermost end 110Am of the first wearing fabric 110, and the uppermost end 111Am of the second wearing fabric 111). This makes it less likely that the crotch air guide portion 112 will come into contact with the neck of the wearer HM. Furthermore, for example, the crotch air guide portion 112 may be semicircular and protrude outward from the uppermost end 106Am of the outer collar fabric 106A of the outer collar 106 and the uppermost end of the inner collar 107 (the uppermost end 108Fm of the adjustment fabric 108F, the uppermost end 110Am of the first wearing fabric 110, and the uppermost end 111Am of the second wearing fabric 111). This makes it possible to prevent the welt air guide section 112 from getting caught on tree branches or the like during work, for example.

[0184] In the above embodiment, the crotch air guide section 112 is sewn and fixed to the center of the upper end of the collar 105. However, this is not limited to this. For example, the crotch air guide section 112 may be sewn and fixed to the entire upper end of the collar 105. This allows the air sent into the garment body 101 by the air blower 1 to be directed not only to the back of the head but also to the sides and front of the head. Alternatively, for example, multiple crotch air guide sections 112 may be sewn and fixed to multiple parts of the upper end of the collar 105. In this case, for example, each of the multiple crotch air guide sections 112 is sewn and fixed to two locations, the right and left ends of the upper end of the collar 105. This allows the multiple crotch air guide sections 112 to guide the air sent into the garment body 101 by the air blower 1 to the left and right head areas, respectively.

[0185] In the above embodiment, the crotch air guide section 112 is sewn and fixed to the center portion OC of the top end 106Aa of the outer collar 106 and the center portion IC of the top end of the inner collar 107. However, this is not limited to this. For example, the crotch air guide section 112 may be sewn and fixed to the entire top end 106Aa of the outer collar 106 and the entire top end of the inner collar 107. Furthermore, for example, multiple crotch air guide sections 112 may be sewn and fixed to each of multiple portions of the top end 106Aa of the outer collar 106 and each of multiple portions of the top end of the inner collar 107. In this case, for example, the multiple crotch air guide sections 112 are sewn and fixed to the left and right end portions of the top end 106Aa of the outer collar 106 and the left and right end portions of the top end of the inner collar 107, respectively. As a result, each of the plurality of crotch air guide portions 112 can guide the air sent into the clothing body 101 by the air blower 1 to the left and right head regions.

[0186] The body temperature regulating garment 100 according to the above embodiment has two air blowers 1 attached to it, but the number of air blowers 1 attached to the fabric 102 is merely an example of two, and is not limited to this embodiment and can be changed as appropriate.

[0187] The body temperature regulating clothing 100 according to the above embodiment is equipped with two Peltier element units 80, but the number of Peltier element units 80 attached to the inner collar 107 is merely an example of two, and is not limited to this embodiment and can be changed as appropriate.

[0188] In the above embodiment, the garment body 101 has two attachment portions 120 on the fabric 102, but this is not limiting. For example, the number, placement positions, and arrangement of attachment portions on the fabric can be changed as appropriate depending on the specifications of the body temperature regulating garment (product) according to the present disclosure, such as the use of the garment and the physique of the wearer.
