Description

[Technical Field]

[0001] The present invention relates to cooling garments and air-cooled jackets. [Background technology]

[0002] Clothing with ventilation functions has been known as a way to combat the heat when working outdoors in the hot sun. Air-blowing clothing draws air into the garment and expels it from the collar or hem, allowing the air to circulate between the garment and the body, giving the wearer a cooling sensation. Some clothing with ventilation functions also incorporates Peltier elements.

[0003] Patent document 1 discloses clothing with an air-blowing function, which has a Peltier element unit at a position that comes into contact with the wearer's neck, and has a double-russell fabric with a certain thickness on the lining of the back of the clothing, and has an air flow path regulated by a pair of passage regulating parts.

[0004] In clothing with an air-blowing function, the Peltier element unit is used with the cooling surface of the Peltier element unit in contact with the wearer's body. Furthermore, to maximize the cooling performance of the Peltier element unit, it is necessary to effectively remove heat from the heat-dissipating surface on the opposite side of the Peltier element unit to the cooling surface. To bring the Peltier element unit into contact with the body, the outer fabric on which the Peltier element unit is mounted must be placed close to the wearer's body. However, placing the clothing fabric close to the wearer's body obstructs the airflow path of the air-blowing function. This can result in insufficient heat removal from the heat-dissipating surface of the Peltier element unit, potentially preventing the Peltier element unit from achieving its full cooling performance.

[0005] [Patent Document 1] Utility Model Registration No. 3244984 Summary of the Invention [Problem to be solved by the invention]

[0006] The present invention has been made in view of the above-mentioned problems, and aims to provide an air-cooled jacket in which the cooling surface of the Peltier element unit can be brought into close contact with the body surface of the wearer. [Means for solving the problem]

[0007] The cooling garment of the present disclosure is a cooling garment comprising an outer fabric and a lining provided on a portion of the back side of the outer fabric and including an element mounting hole for mounting a Peltier element unit having a cooling surface and a heat dissipation surface on the side opposite the cooling surface, with the cooling surface facing inward, the outer fabric and the lining being restrained by restraining portions located at two different positions in the width direction, and between the two restraining portions the length of the lining in the width direction is shorter than the corresponding length of the outer fabric in the width direction.

[0008] The air-cooled jacket according to the present disclosure includes the cooling garment, a fan unit attached to the fan mounting hole, and a Peltier element unit attached to the element mounting hole.

[0009] According to the present disclosure, by including a Peltier element unit in a cooling garment, the lining can bring the cooling plate of the Peltier element unit into close contact with the wearer's body, thereby providing cooling garments that enable the cooling capacity of the Peltier element unit to be fully utilized. Furthermore, by further including a fan unit in the cooling garment, the cooling plate of the Peltier element unit can be brought into close contact with the wearer's body while ensuring a flow path for circulating air from the fan unit on the heat dissipation surface of the Peltier element unit. Furthermore, the cooling garment can be provided as an air-cooled jacket equipped with a fan unit and a Peltier element unit. [Brief explanation of the drawings]

[0011] <First Example> An air-cooling jacket and a cooling garment according to a first embodiment of the present disclosure will be described below with reference to Figures 1 to 5. Figure 1 shows the interior of the air-cooling jacket according to the first embodiment of the present disclosure as viewed from the front. Figure 2 is a front view of the cooling garment according to the first embodiment of the present disclosure. Figure 3 is a back view of the cooling garment according to the first embodiment of the present disclosure. Figure 4 is a left side view of the cooling garment according to the first embodiment of the present disclosure. Figure 5 shows the interior of the cooling garment according to the first embodiment of the present disclosure as viewed from the front. In the following description, the left-right direction in Figure 1 may be referred to as the width direction, and the up-down direction as the length direction.

[0012] It should be noted that this embodiment is merely an example, and the technical scope of the present invention is not limited to this. In this embodiment, a sleeveless vest type is described, but the same configuration can be adopted even if the vest has sleeves.

[0013] <Air-cooled jacket> The air-cooled jacket 1 shown in FIGS. 1 to 5 includes an outer fabric 12, a lining 40, a Peltier element unit 44, a fan unit 54, and a power supply 60. The air-cooled jacket 1 has a zipper 16c at the center of the front. Gathers 38 are provided around almost the entire hem of the air-cooled jacket 1. Nylon fabric is used as the material for the outer fabric 12. Note that the material for the outer fabric 12 is not limited to nylon fabric, and any thin, air-impermeable fabric can be used.

[0014] The outer fabric 12 comprises a front body 16, a back body 20, a shoulder yoke 22, a waistband 30, and a collar 36. The outer fabric 12 is formed by sewing these components together. The widthwise edge of the front body 16 is sewn to the widthwise edge of the waistband 30. The upper side of the back body 20 in the length direction is sewn to the shoulder yoke 22, and each widthwise edge of the back body 20 is sewn to the widthwise edge of the waistband 30 opposite to the edge sewn to the front body 16. The shoulder yoke 22 and front body 16 are sewn together at the shoulders. The collar 36 is sewn to the upper ends of the front body 16 and shoulder yoke 22.

[0015] The front body 16 is the front portion of the cooling garment 10. The front body 16 includes a right front body 16a, a left front body 16b, and a zipper 16c. The right front body 16a and the left front body 16b have symmetrical shapes. The right front body 16a and the left front body 16b are configured to be put on and taken off by opening and closing the zipper 16c located in the center in the width direction.

[0016] The front body 16 is provided with pockets 18 at positions below the center in the length direction. The right pocket 18 further has an inner pocket 18a and a cable hole 18b inside. The inner pocket 18a stores a power supply 60. The entrance to the inner pocket 18a is provided with a hook-and-loop fastener. The end of the cable hole 18b is snap-fastened.

[0017] The front body 16 is sewn to the shoulder yoke 22 and collar 36 at its upper end in the length direction. The front body 16 has cuffs 32 at its end opposite to where the zipper 16c is attached in the width direction, and is piped with tape. The front body 16 may be made of multiple pieces of fabric and formed as a single piece when sewn together.

[0018] The back body 20 is the portion of the back of the cooling garment 10 that extends from the back to the hem. The back body 20 is provided with fan mounting holes 14 and tabs 21. Two fan mounting holes 14 are provided side by side in the width direction of the back body 20 at the waist position when the garment is worn by a wearer. The tabs 21 are made of tape material in a loop shape that can be opened and closed with a hook-and-loop fastener. The tabs 21 are provided next to the holes 14 on the back side of the back body 20.

[0019] The back body 20 is sewn to the shoulder yoke 22 at its upper end in the length direction, and is sewn to the waistbands 30a, 30b at each end in the width direction.

[0020] The shoulder yoke 22 is a part that extends from the back to the collar on the back side of the air-cooled jacket 1. In this embodiment, the shoulder yoke 22 is described as a separate member from the back body 20, but the shoulder yoke 22 and the back body 20 may be an integrated member.

[0021] The shoulder yoke 22 is sewn to the collar 36 at its upper end in the length direction, and to the back body 20 at its lower end in the length direction. The upper sides of each widthwise end of the shoulder yoke 22 are sewn to the front body 16. The lower sides of each widthwise end of the shoulder yoke 22 form cuffs 32, which are piped with tape. The shoulder yoke 22 is symmetrical with respect to the center line in the width direction.

[0022] The shoulder yoke 22 has a folding section 26. The folding section 26 has a structure in which the fabric is folded twice in different directions at a predetermined width in the width direction. A fold 28 is formed at each of the two folded sections of the folding section 26. In other words, the cross section of the folding section 26 when viewed from the length direction has a Z-shape. The folding section 26 is provided from the top end to the bottom end of the shoulder yoke 22 in the length direction.

[0023] The folded portions 26 are provided at two different positions in the width direction of the shoulder yoke 22, spaced a predetermined distance apart. The widthwise distance between the two folded portions 26 is dimensioned to match the width of the heat sink 44b of the Peltier element unit 44. The two folded portions 26 are formed symmetrically with respect to the center line in the width direction. The two folded portions 26 function as a pair, forming so-called box pleats.

[0024] The two folding parts 26 have the Peltier element unit 44 at the center between the two folding parts 26 in a plan view of the air-cooled jacket 1 seen from the back side. That is, when the air-cooled jacket 1 is worn, the two folding parts 26 are provided at the center in the width direction of the back and from the back to the collar in the length direction.

[0025] Folding section 26 is configured so that the length of the portion folded between two folds 28 (hereinafter referred to as the "folded length") increases from bottom to top in the length direction. That is, the folded length of folding section 26 at the upper side in the length direction is longer than the folded length at the lower side in the length direction.

[0026] The waist bands 30 are provided on both sides of the air-cooled jacket 1. The upper end of the waist band 30 in the length direction forms part of the cuffs 32. The upper end of the waist band 30 in the length direction is piped with tape. The lower end of the waist band 30 in the length direction forms part of the hem and is provided with gathers 38. One end of the waist band 30 in the width direction is sewn to the front body 16, and the other end in the width direction is sewn to the back body 20. The waist band 30 is provided with folded portions 34 at two different positions in the width direction, extending to the cuffs 32. The two folded portions 34 function as a pair and are so-called box pleats.

[0027] The collar 36 is provided at the upper end of the air-cooled jacket 1. The collar 36 is provided so that the fabric covers the entire circumference of the neck, and has a zipper 16c on the front side that connects to the front body 16. The lower end of the collar 36 in the length direction is sewn to the front body 16 and the shoulder yoke 22. The two folded portions 26 on the back of the collar 36 are formed by connecting to the shoulder yoke 22.

[0028] The lining 40 is provided on the back side of the shoulder yoke 22. The lining 40 has an element mounting hole 42. The lining 40 is generally trapezoidal in shape, with both ends of the base of the trapezoid carved out in an arc shape. The element mounting hole 42 is provided in the center of the lining 40 in the width direction and length direction. Here, the element mounting hole 42 has a diameter of approximately 5 cm.

[0029] The width dimension of the lining 40 is set smaller than the width dimension of the corresponding shoulder yoke 22. Here, "the width dimension of the corresponding shoulder yoke 22" means that, when comparing the lining 40 with the shoulder yoke 22 to which the lining 40 is attached, the width dimension of the lining 40 is shorter than the width dimension of the shoulder yoke 22 at each position in the garment length direction. In other words, the shape of the widthwise end of the lining 40 is substantially the same as the shape of the widthwise end of the shoulder yoke 22, with only the widthwise length differing. The widthwise length of the lining 40 is set within a numerical range of less than 95% to 75% of the widthwise length of the corresponding shoulder yoke 22. Preferably, the widthwise length of the lining 40 is set within a numerical range of 90% to 80% of the widthwise length of the corresponding shoulder yoke 22. More preferably, the widthwise length of the lining 40 is set within a numerical range of 88% to 83% of the widthwise length of the corresponding shoulder yoke 22. The widthwise length of the outer fabric 12 and the lining 40 is the length when no tension is applied in the widthwise direction. The widthwise length of the outer fabric 12 and the lining 40 is the length without taking into account shrinkage due to use over time, including shrinkage due to washing.

[0030] The dimension of the lining 40 in the length direction is set smaller than the dimension of the shoulder yoke 22 in the length direction. The lower end of the lining 40 in the length direction is located higher than the lower end of the shoulder yoke 22 in the length direction. In other words, the lower end of the folded portion 26 of the shoulder yoke 22 is located lower than the lower end of the lining 40 in the length direction.

[0031] The lining 40 is made of a mesh fabric. Here, the mesh fabric of the lining 40 is configured so that the size of the mesh holes is such that air can freely pass through from one side of the fabric to the other side.

[0032] The lining 40 has stretchability at least in the width direction. Because the lining 40 has stretchability, a predetermined tension can be generated in the width direction even when wearers of different body shapes wear the air-cooled jacket 1.

[0033] The lining 40 is sewn to the shoulder yoke 22, which is the outer fabric 12, at the shoulder lines at both ends in the width direction. In addition, the underside of each end of the lining 40 in the width direction is sewn to the shoulder yoke 22. Here, the lining 40 is sewn together with the front body 16 together with the shoulder yoke 22. The undersides of both ends of the lining 40 in the width direction form part of the cuffs 32, and the ends of the lining 40, together with the ends of the shoulder yoke 22, are piped with elastic tape material.

[0034] It should be noted that the lining 40 may be sewn to the outer fabric 12 at two different positions in the width direction, and the positions at which the lining 40 is sewn to the outer fabric 12 are not limited to the ends in the width direction. For example, the lining 40 may be constrained to the outer fabric 12 at a position more inward than the ends in the width direction.

[0035] The upper and lower ends of the lining 40 in the length direction are not sewn to other fabrics. The upper and lower ends of the lining 40 in the length direction are simply piped with tape. In other words, the lining 40 is not constrained by the outer fabric 12 in the length direction.

[0036] Here, the portions of the lining 40 sewn to the shoulder yoke 22 are restrained from moving in the face direction relative to the shoulder yoke 22. The portions of the lining 40 sewn to the shoulder yoke 22 are referred to as restrained portions 24. The lining 40 has restrained portions 24 formed from the upper end to the lower end in the length direction at both ends in the width direction. In the restrained portions 24, the lining 40 and the shoulder yoke 22 are restrained in the face direction. On the other hand, in portions other than the restrained portions 24, i.e., in unsewn portions, the lining 40 is not restrained by the shoulder yoke 22 in any way. In this way, the lining 40 and the shoulder yoke 22, which is the outer fabric 12, are restrained by the restrained portions 24 located at two different positions in the width direction.

[0037] <Fan unit> The fan unit 54 takes in outside air and sends it into the air-cooled jacket 1, thereby generating an air flow inside the air-cooled jacket 1. The fan unit 54 includes an impeller, a rotary motor, a casing, and a power cable 54a. Two fan units 54 are provided, and are attached to the fan attachment holes 14 provided in the back body 20.

[0038] The impeller rotates to draw in air from the axial direction and push it out in the radial direction. The impeller is a mixed-flow impeller with multiple blades arranged around the axis. The impeller is connected to a rotary motor, and rotates around the axis when the rotary motor rotates.

[0039] The rotary motor is driven by a direct current to rotate continuously about its axis and includes a power cable 54a for connecting to a power source 60.

[0040] The power cable 54a supplies driving power for the rotary motor from a power supply 60. One end of the power cable 54a is electrically connected to the rotary motor, and the other end is connected to the power supply 60. The power cables 54a coming out of the two fan units 54 join together and extend to the other end as a single cable.

[0041] The power cable 54a is equipped with a power switch 54b, and by operating the power switch 54b, it is possible to turn the power supply 60 on and off as well as to change the rotation speed of the rotary motor. The power switch 54b is equipped with an indicator light (not shown), and the operating state can be indicated by lighting the indicator light.

[0042] The casing has a hollow structure and a flattened cylindrical exterior shape. The casing has a flange on the outer periphery of the cylindrical part for attaching to the fan mounting hole 14. The casing has a mesh structure, allowing air to circulate inside and outside the casing. The casing houses the impeller, rotary motor, and power cable 54a inside. The flange is attached by sandwiching the fabric.

[0043] <Peltier element unit> The Peltier element unit 44 cools the body through contact. The Peltier element unit 44 includes a Peltier element (not shown), a cooling plate 44a, a heat sink 44b, a power cable 44c, and a casing. The Peltier element unit 44 is attached to an element attachment hole 42 provided in the lining 40. The Peltier element unit 44 is attached to the element attachment hole 42 with the cooling plate 44a facing the body BS.

[0044] A Peltier element is formed by joining two different metals together, and when an electric current is passed through the joint surface, the temperature of one metal rises while the temperature of the other metal drops. A metal plate is provided on the surface of the Peltier element where the temperature drops (hereinafter referred to as "cooling plate 44a"). On the other hand, a metal plate is also provided on the surface of the Peltier element where the temperature rises (hereinafter referred to as "heat sink 44b"). Here, multiple holes are formed in heat sink 44b. Cooling plate 44a and heat sink 44b are held by a casing and are configured as a single unit with the Peltier element unit 44.

[0045] The power cable 44c supplies driving power to the Peltier element from the power supply. One end of the power cable 44c is electrically connected to the Peltier element, and the other end extends outside the casing. A connection terminal for connecting to a power source 60 is attached to the other end of the power cable 44c. The power cable 44c has a power switch 44d for turning the power of the Peltier element unit 44 on and off.

[0046] The casing has a hollow cylindrical structure and constitutes the outer shell of the Peltier element unit 44. The casing has a flange portion on the outer periphery of the cylindrical shape. Slits are formed in the cylindrical portion of the casing. Air that enters through the slits in the cylindrical portion of the casing can exit through holes provided in the heat sink 44b. The casing is configured to allow air to circulate inside.

[0047] The casing houses the Peltier element inside, and one bottom of the cylindrical shape is made up of a cooling plate 44a, and the other bottom is made up of a heat sink 44b. The cooling plate 44a and the heat sink 44b are each made of a metal material and have thermal conductivity.

[0048] The flange is provided on the outer periphery of the cylindrical part of the casing on the heat sink 44b side. The casing is attached by sandwiching the fabric with the flange. Here, since the flange is on the cylindrical heat sink 44b side of the casing, the cooling plate 44a side of the Peltier element unit 44 attached to the lining 40 protrudes from the lining 40 toward the body BS.

[0049] The Peltier element unit 44 may have an exhaust fan on the heat sink side, and the flange may be provided on the outer periphery of the cylindrical part of the casing on the cooling plate 44a side. In this case, the Peltier element unit 44 attached to the back 40 has the cooling plate 44a side protruding from the back 40 toward the body, and the heat sink 44b side protruding from the back 40 toward the outer fabric.

[0050] <Power supply section> The power supply 60 stores the power to be supplied. The power supply 60 is a battery pack. The power supply 60 has a secondary battery, a connection terminal unit, an indicator light (not shown), and a control unit. The power supply 60 is configured to be able to supply power at a voltage of 5 volts or more and 12 volts or less.

[0051] The secondary battery is a rechargeable battery. The secondary battery is a lithium-ion secondary battery. The secondary battery is not limited to a lithium-ion secondary battery, and a rechargeable battery such as a nickel-cadmium battery can also be used. The power supply 60 is not limited to a secondary battery, and may be a dry cell battery.

[0052] The connection terminal section has three connection terminals. The first connection terminal is connected to the power cable 44c from the Peltier element unit 44. The second connection terminal is connected to the power cable 54a from the fan. The third connection terminal is a charging terminal for connecting to a commercial power source via an AC adapter. The connection terminal is a USB (Universal Serial Bus) terminal. Furthermore, the connection terminal is not limited to a USB terminal and may be a DC plug.

[0053] An indicator light (not shown) indicates the operating state of the power supply 60. The indicator light is an LED (Light-Emitting Diode). The indicator light is configured to light up when power is being output or input.

[0054] A control unit (not shown) controls the operation of power supply 60 and manages the remaining charge of the secondary battery. When the control unit detects that power switch 44d, 54b of power cable 44c, 54a connected to at least one of the first and second connection terminals has been turned on, it starts supplying power at a predetermined voltage. Furthermore, when an AC adapter connected to a commercial power source is connected to the third connection terminal, the control unit charges the secondary battery and stops charging when the remaining charge of the secondary battery reaches or exceeds a predetermined level.

[0055] <About the width of the lining> The length of the lining in the width direction will be described below with reference to Fig. 6. Fig. 6 is a top view for explaining the length of the outer fabric and the lining in the width direction of the present disclosure.

[0056] As described above, the shoulder yoke 22 and lining 40, which are the outer fabric 12, are restrained by the restraining portions 24 located at two different positions in the width direction. Between the two restraining portions 24, the length of the lining 40 in the width direction is shorter than the length of the corresponding shoulder yoke 22 in the width direction. Therefore, when the air-cooled jacket 1 is worn, tension occurs in the entire circumferential direction, causing the lining 40 to be pulled. As a result, the Peltier element unit 44 attached to the lining 40 is pressed against the wearer's body BS, and the cooling plate 44a comes into contact with the lining 40. Meanwhile, no tension occurs in the shoulder yoke 22 between the two restraining portions 24 in the width direction, so the shoulder yoke 22 has excess length in the width direction. Therefore, when air is sent into the air-cooled jacket 1 by the fan unit 54, the shoulder yoke 22 can bulge outward, allowing air to circulate between the lining 40 and the shoulder yoke 22.

[0057] <About the folding part> The folding section 26 will be described below with reference to Figures 7 and 8. Figure 7 is a top view illustrating the structure of the folding section of the present disclosure. Figure 8 is a top view illustrating the folding section of the present disclosure in an unfolded state. According to Figure 7, the two folding sections 26 are in a folded state. Here, the two folding sections 26 are provided so that the Peltier element unit 44 is located at the center in the width direction, and the two folding sections 26 are provided symmetrically with respect to the center line in the width direction.

[0058] 8 shows the two folded sections 26 in an unfolded state. When inflating outward, the folded ridges 28 of the folded sections 26 can be used as a reference for unfolding. This allows the air flow path to be positioned in contact with the heat sink 44b of the Peltier element unit 44.

[0059] <Air flow inside the jacket> The air flow in the air-cooled jacket 1 according to the first embodiment will be described below with reference to Figures 9 and 10. Figure 9 shows the air flow when the air-cooled jacket of the present disclosure is viewed from the back. Figure 10 shows the air flow in the air-cooled jacket of the present disclosure.

[0060] 9, a fan unit 54 is attached to the fan mounting hole 14 in the rear body 20 on the back of the air-cooled jacket 1, and a Peltier element unit 44 is attached to the element mounting hole 42 in the lining 40. The front zipper 16c of the air-cooled jacket 1 is closed, and the gap between the outer fabric 12 and the wearer's body BS is closed by gathers 38 at the lower end of the air-cooled jacket 1.

[0061] First, the fan unit 54 sends air AC outside the air-cooled jacket 1 into the air-cooled jacket 1. The air sent into the air-cooled jacket 1 is diffused in the space between the wearer's body BS and the back body 20 at the rear body 20 portion.

[0062] Thereafter, the air in the rear body portion 20 of the air-cooled jacket 1 is pushed out by the air successively sent out from the fan unit 54, and moves upward in the garment length direction.

[0063] At the shoulder yoke 22 portion of the air-cooled jacket 1, the air passage between the outer fabric 12 and the wearer's body BS is divided by the lining 40 into an outer air passage on the outer fabric 12 side of the lining 40 and a body-side air passage on the body BS side of the lining 40. The air that has moved to the boundary position with the shoulder yoke 22 inside the air-cooled jacket 1 flows partly through the outer air passage and partly through the body-side air passage.

[0064] The air Af flowing through the front-side air passage moves upward in the garment length direction between the lining 40 and the outer fabric 12. Here, the air Af flowing through the front-side air passage moves while coming into contact with the heat sink 44b of the Peltier element unit 44 provided in the lining 40. In other words, the air Af flowing through the front-side air passage removes heat from the heat sink 44b of the Peltier element unit 44.

[0065] Air Ab flowing through the body-side air passage moves upward in the space between the lining 40 and the body BS. The air Ab flowing through the body-side air passage enters the casing through slits in the casing of the Peltier element unit 44 and exits through holes in the heat sink 44b, thereby removing heat from the Peltier element unit 44. A portion of the air Ab flowing through the body-side air passage passes through the mesh holes in the lining 40 and moves to the front-side passage, where it merges with air Af flowing through the front-side passage.

[0066] After passing the upper end of the lining 40 in the air-cooled jacket 1, the air Af that has circulated through the front-side air passage and the air Ab that has circulated through the body-side air passage join together and flow out of the air-cooled jacket 1 from the collar (air AE).

[0067] <Second Example> An air-cooled jacket and cooling garment according to a second embodiment of the present disclosure will be described below with reference to FIGS. 11 and 12. FIG. 11 shows the interior of the air-cooled jacket according to the second embodiment of the present disclosure as viewed from the front. FIG. 12 shows the interior of the cooling garment according to the second embodiment of the present disclosure as viewed from the front. The cooling garment 110 according to the second embodiment differs from the cooling garment 10 according to the first embodiment in that a fan-equipped hole 114 is provided in the waistband 130 and the folded portion 126 on the back extends to the vicinity of the waist. The air-cooled jacket 101 according to the second embodiment is provided with a fan unit 54 in the fan mounting hole 114 provided in the waistband 130. Note that descriptions of parts of the second embodiment that overlap with those of the first embodiment will be omitted.

[0068] As shown in Figures 11 and 12, the back body 120 is the portion of the cooling garment 110 on the back, stretching from the waist to the hem. The back body 120 is sewn to the shoulder yoke 122 at its upper end in the length direction, and to the waistbands 130a and 130b at each end in the width direction. The back body 120 is provided with tabs 121 and cable holders 121a. The tabs 121 are provided near each end in the width direction on the back side of the back body 120. Multiple cable holders 121a are provided along the length direction at the end of the back side of the back body 120 and the shoulder yoke 122 on the waistband 130a side in the width direction.

[0069] The shoulder yoke 122 is a portion that extends from the waist to the collar on the back of the air-cooled jacket 101. The shoulder yoke 122 includes a folding portion 126. The folding portion 126 is provided from the upper end to the lower end in the length direction of the shoulder yoke 122. In other words, the folding portion 126 extends from the collar to the waist on the back.

[0070] The waist portions 130a and 130b are provided on the sides of the air-cooled jacket 101. The waist portions 130a and 130b each have a fan mounting hole 114 and a folding portion 134. The fan mounting hole 114 is provided on the back body 120 at a position at waist height when the wearer is wearing the air-cooled jacket 101.

[0071] The waist regions 130a, 130b have folded sections 134 at two different positions in the width direction. The folded sections 134 are constructed by folding the fabric twice in different directions at a predetermined width. A fold is formed at the folded section of the folded section 134. In other words, the cross section of the folded section 134 when viewed from the length direction is Z-shaped. The folded sections 134 each extend from the position of the fan mounting hole 114 in the length direction to the cuff 132. The two folded sections 134 are formed symmetrically with respect to the center of the width direction of the waist regions 130a, 130b. The two folded sections 134 function as a pair, forming so-called box pleats. The portion formed by the upper ends of the waist regions 130a, 130b of the cuff 132 is piped with non-elastic tape material.

[0072] A folded structure is formed in each portion of cuff 132 that connects to two folded portions 134, and functions as a single unit with folded portions 134. That is, when folded portions 134 expand outward, the folded structure of cuff 132 also expands outward, and when folded portions 134 return to their folded state, the folded structure of cuff 132 also returns to its folded state. As the folded structure of cuff 132 expands outward, the cross-sectional area in the length direction increases.

[0073] <Air flow inside the jacket> The air flow in the air cooling jacket 101 according to the second embodiment will be described below with reference to Fig. 13. Fig. 13 shows the air flow in the air cooling jacket according to the second embodiment of the present disclosure.

[0074] 13, as described above, the fan unit 54 is attached to the fan mounting hole 114 in the side waist 130 of the air-cooled jacket 101, and the Peltier element unit 44 is attached to the element mounting hole 142 in the lining 140 on the back. The front zipper 116c of the air-cooled jacket 101 is closed, and the gap between the outer fabric 12 and the wearer's body BS is closed by the gathers 138 at the bottom end of the air-cooled jacket 101.

[0075] First, the fan unit 54 sends air CA outside the air-cooled jacket 101 into the air-cooled jacket 101. The air sent into the air-cooled jacket 101 is diffused between the waistband 130 and the wearer's body BS, and a part of the air is diffused into the space between the back body 120 and the body BS.

[0076] Thereafter, the air in the waist 130 of the air-cooled jacket 101 is pushed out by the air successively sent from the fan unit 54 and moves upward in the garment length direction. Here, the subsequent flow of the air that has moved to the back body 120 is the same as in Example 1.

[0077] Air in the region of the waist 130 in the air-cooled jacket 101 moves upward in the garment length direction between the waist 132 and the body BS and flows out through the cuffs 132 (air UA). Here, the pressure of the air sent in by the fan unit 54 causes the folded portions 134 of the waist 130 in the garment length direction to expand outward. This expands the air path between the outer fabric 12 and the wearer's body BS. Furthermore, as the folded portions 134 of the waist 130 expand outward, the folded structure formed in the cuffs 132 that are continuous with the folded portions 134 also expands, widening the opening of the cuffs 132. This allows more air to circulate between the waist 130 and the body BS, and also allows more air UA to be exhausted from the cuffs 132.
