Description

[Technical field]

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

[0002] Clothing with a ventilation function has been known as a measure to protect against the heat when working outdoors under the scorching sun. Clothing with a ventilation function draws in air and expels it from the collar or hem, allowing the air to circulate between the clothing and the body, giving the wearer a feeling of coolness. Some clothing with a ventilation function is equipped with a Peltier element in addition to the ventilation function.

[0003] Patent Document 1 discloses clothing with an air-blowing function, which has a Peltier element unit located at a position that comes into contact with the neck of the wearer of the clothing, and has a double-russell fabric of 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 by bringing the cooling surface of the Peltier element unit into contact with the wearer's body. In order to allow the Peltier element unit to exert a greater cooling performance, it is necessary to effectively remove heat from the heat dissipation surface on the opposite side of the Peltier element unit to the cooling surface. In order to bring the Peltier element unit into contact with the body, it is necessary to bring the outer fabric on which the Peltier element unit is mounted close to the wearer's body. On the other hand, if the fabric of the clothing is brought close to the wearer's body, the flow path of air by the air blowing function is obstructed. For this reason, there is a risk that the heat dissipation surface of the Peltier element unit cannot be sufficiently removed, and the cooling performance of the Peltier element unit will not be exerted.

[0011] <First Example> An air-cooled jacket and a cooling garment according to a first embodiment of the present disclosure will be described below with reference to Figs. 1 to 5. Fig. 1 shows the inside of the air-cooled jacket according to the first embodiment of the present disclosure as viewed from the front. Fig. 2 is a front view of the cooling garment according to the first embodiment of the present disclosure. Fig. 3 is a back view of the cooling garment according to the first embodiment of the present disclosure. Fig. 4 is a left side view of the cooling garment according to the first embodiment of the present disclosure. Fig. 5 shows the inside 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 Fig. 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 material 12, a lining material 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 over almost the entire periphery of the hem of the air-cooled jacket 1. Nylon fabric is used as the material for the outer material 12. Note that the material for the outer material 12 is not limited to nylon fabric, and any fabric that is thin and does not easily allow air to pass through can be used.

[0014] The outer fabric 12 includes 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 end of the front body 16 in the width direction is sewn to the end of the waistband 30 in the width direction. The upper side of the back body 20 in the length direction is sewn to the shoulder yoke 22, and each end in the width direction is sewn to the end of the waistband 30 opposite to the end sewn to the front body 16 in the width direction. The shoulder yoke 22 and the front body 16 are sewn at the shoulders. The collar 36 is sewn to the upper ends of the front body 16 and the 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 fastener 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 removable by opening and closing a fastener 16c located in the center in the width direction.

[0016] The front body 16 has pockets 18 at positions below the center in the length direction. The right pocket 18 has an inner pocket 18a and a cable hole 18b on the inside. A power source 60 is stored in the inner pocket 18a. A hook-and-loop fastener is provided at the entrance of the inner pocket 18a. The end of the cable hole 18b is can-fastened.

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

[0018] The rear body 20 is the portion of the back of the cooling garment 10 that extends from the back to the hem. The rear body 20 has fan mounting holes 14 and tabs 21. Two fan mounting holes 14 are provided side by side in the width direction of the rear 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 beside the holes 14 on the back side of the rear 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 of the back of the air-cooled jacket 1. In this embodiment, the shoulder yoke 22 is described as a separate member from the rear body 20, but the shoulder yoke 22 and the rear 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 end of the shoulder yoke 22 in the width direction are sewn to the front body 16. The lower sides of each end of the shoulder yoke 22 in the width direction form cuffs 32, which are piped with tape material. The shoulder yoke 22 is shaped symmetrically with respect to the center line in the width direction.

[0022] The shoulder yoke 22 has a folded portion 26. The folded portion 26 has a structure in which the fabric is folded twice in different directions by a predetermined width in the width direction. A fold 28 is formed at each of the two folded portions of the folded portion 26. In other words, the folded portion 26 has a Z-shaped cross section when viewed from the length direction. The folded portion 26 is provided from the upper end to the lower 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, with a predetermined distance between them. The distance between the two folded portions 26 in the width direction is a dimension that matches 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 and are so-called box pleats.

[0024] The two folding parts 26 are provided with 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, 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 when the air-cooled jacket 1 is worn.

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

[0026] The narrow waist 30 is provided on both sides of the air-cooled jacket 1. The upper end of the narrow waist 30 in the length direction forms part of the cuffs 32. The upper end of the narrow waist 30 in the length direction is piped with a tape material. The lower end of the narrow waist 30 in the length direction forms part of the hem and is provided with gathers 38. One end of the narrow waist 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 narrow waist 30 is provided with folded parts 34 at two different positions in the width direction and extends to the cuffs 32. The two folded parts 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 fastener 16c on the front side that extends from 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 parts 26 on the back side of the collar 36 are formed by connecting with 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 attachment 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 attachment hole 42 is provided in the center of the lining 40 in the width direction and length direction. Here, the element attachment hole 42 has a diameter of about 5 cm.

[0029] The width dimension of the lining 40 is set to be 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 provided, the width dimension of the lining 40 is shorter than the width dimension of the shoulder yoke 22 at each position in the length direction. In other words, the shape of the end of the lining 40 in the width direction is almost the same as the shape of the end of the shoulder yoke 22 in the width direction, and only the length dimension in the width direction is different. The length dimension of the lining 40 in the width direction is set within a numerical range of less than 95% to 75% or more of the length dimension of the corresponding shoulder yoke 22 in the width direction. Preferably, the length dimension of the lining 40 in the width direction is set within a numerical range of 90% or less to 80% or more of the length dimension of the corresponding shoulder yoke 22 in the width direction. More preferably, the length dimension of the lining 40 in the width direction is set within a numerical range of 88% or less to 83% or more of the length dimension of the corresponding shoulder yoke 22 in the width direction. 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 aging, including shrinkage due to washing.

[0030] The dimension of the lining 40 in the length direction is set to be smaller than the dimension in the length direction of the shoulder yoke 22. The lower end of the lining 40 in the length direction is located above 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 below 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 such 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 elasticity at least in the width direction. Since the lining 40 has elasticity, a predetermined tension can be generated in the width direction even when the air-cooled jacket 1 is worn by wearers with different body shapes.

[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 undersides of both ends of the lining 40 in the width direction are 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 and 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 position at which the lining 40 is sewn to the outer fabric 12 is not limited to the end in the width direction. For example, the lining 40 may be constrained to the outer fabric 12 at a position inside the end 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 material. In other words, the lining 40 is not restrained by the outer fabric 12 in the length direction.

[0036] Here, the portion of the lining 40 sewn to the shoulder yoke 22 is restrained from moving in the surface direction relative to the shoulder yoke 22. The portion of the lining 40 sewn to the shoulder yoke 22 is referred to as the restraining portion 24. The lining 40 has the restraining portion 24 formed from the upper end to the lower end in the length direction at both ends in the width direction. In the restraining portion 24, the lining 40 and the shoulder yoke 22 are restrained in the surface direction. On the other hand, in the portion other than the restraining portion 24, i.e., the unsewn portion, the lining 40 is not restrained by the shoulder yoke 22 at all. In this way, the lining 40 and the shoulder yoke 22, which is the outer fabric 12, are restrained by the restraining 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 mounting 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 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 connection to a power source 60.

[0040] The power cable 54a supplies driving power for the rotary motor from a power source 60. One end of the power cable 54a is electrically connected to the rotary motor, and the other end is connected to the power source 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 on and off the power supply 60 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 has a flattened cylindrical exterior shape. The casing has a flange on the outer periphery of the cylindrical portion for attachment to the fan attachment hole 14. The casing has a net structure, allowing air to circulate between the inside and outside of the casing. The casing houses the impeller, the rotary motor, and the 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. Here, 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 bonding different metals together, and has the property that when a current is passed through the bonded 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, a plurality of holes are formed in heat sink 44b. Cooling plate 44a and heat sink 44b are held by a casing and are configured as one unit with Peltier element unit 44.

[0045] The power cable 44c supplies driving power to the Peltier element from a 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 cylindrical hollow 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 flow inside.

[0047] The casing contains the Peltier element inside, and one bottom of the cylindrical shape is formed by a cooling plate 44a, and the other bottom is formed by 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. 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 towards 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 side, and the heat sink 44b side protruding from the back 40 toward the outer fabric side.

[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, and an indicator lamp and a control unit (not shown). The power supply 60 is configured to be capable of supplying 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 storage battery can be used. The power supply 60 is not limited to a secondary battery, and may be a dry cell.

[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. In addition, 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 and when power is being input.

[0054] The control unit (not shown) controls the operation of the power source 60 and manages the remaining charge of the secondary battery. When the control unit detects that the power switch 44d, 54b of the power cable 44c, 54a connected to at least one of the first connection terminal and the second connection terminal is turned on, the control unit starts supplying power at a predetermined voltage. 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 ends charging when the remaining charge of the secondary battery reaches or exceeds a predetermined remaining charge.

[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 the lining 40, which are the outer fabric 12, are restrained by the restraining parts 24 at two different positions in the width direction. Between the two restraining parts 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, the lining 40 is in a pulled state due to the tension generated in the entire circumferential direction when the air-cooled jacket 1 is worn. 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 it. On the other hand, since no tension is generated in the width direction in the shoulder yoke 22 between the two restraining parts 24, the shoulder yoke 22 is in a state of 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 protrude outward, and air can 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 Figs. 7 and 8. Fig. 7 is a top view for explaining the structure of the folding section of the present disclosure. Fig. 8 is a top view for explaining the state in which the folding section of the present disclosure is unfolded. According to Fig. 7, the two folding sections 26 are in a folded state. Here, the two folding sections 26 are provided such 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 state in which the two folded sections 26 are unfolded. When inflating outward, the folded sections 26 can unfold with the folds 28 of the respective folded sections 26 as a reference. This allows the air flow path to be in a position that comes into 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 fastener 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 rear body 20 at the rear body 20 portion.

[0062] Thereafter, the air in the rear body 20 area 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 in 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 moves to the position of the boundary with the shoulder yoke 22 in the air-cooled jacket 1 flows partly through the outer air passage and the other part 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 front material 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. That is, the air Af flowing through the front-side air passage removes heat from the heat sink 44b of the Peltier element unit 44.

[0065] The 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 the slits in the casing of the Peltier element unit 44 and exits through the 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 the 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 flowed through the front side air passage and the air Ab that has flowed 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> Hereinafter, an air-cooled jacket and a cooling garment according to a second embodiment of the present disclosure will be described with reference to Figs. 11 and 12. Fig. 11 shows the inside of an air-cooled jacket according to a second embodiment of the present disclosure as viewed from the front. Fig. 12 shows the inside of a cooling garment according to a second embodiment of the present disclosure as viewed from the front. A cooling garment 110 according to the second embodiment is different from the cooling garment 10 according to the first embodiment in that a fan-attached hole 114 is provided in a narrow waist 130 and a folded portion 126 on the back extends to the vicinity of the waist. An air-cooled jacket 101 according to the second embodiment is provided with a fan unit 54 in a fan attachment hole 114 provided in a narrow waist 130. Note that a description of parts of the second embodiment that overlap with the first embodiment will be omitted.

[0068] 11 and 12, the rear body 120 is a portion of the back of the cooling garment 110 that extends from the waist to the hem. The upper end of the rear body 120 in the length direction is sewn to the shoulder yoke 122, and each end in the width direction is sewn to the waist portions 130a, 130b. The rear body 120 has a tab 121 and a cable holder 121a. The tabs 121 are provided near each end in the width direction on the back side of the rear body 120. A plurality of cable holders 121a are provided along the length direction at the ends of the back side of the rear body 120 and the shoulder yoke 122 on the waist portion 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. That is, the folding portion 126 extends from the collar to the waist on the back.

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

[0071] The narrow waists 130a and 130b have folded sections 134 at two different positions in the width direction. The folded sections 134 have a structure in which the fabric is folded over twice in different directions at a predetermined width in the width direction. A fold is formed at the folded-over portion of the folded section 134. That is, the folded section 134 has a Z-shaped cross section when viewed from the length direction. The folded sections 134 each extend from the position of the fan mounting hole 114 in the length direction to the cuffs 132. The two folded sections 134 are formed symmetrically with respect to the center of the narrow waists 130a and 130b in the width direction. The two folded sections 134 function as a pair, so-called box pleats. The portion formed by the upper ends of the narrow waists 130a and 130b of the cuffs 132 is piped with a non-elastic tape material.

[0072] A folded structure is formed in each of the portions of cuff 132 that are connected to the two folded sections 134, and functions as one unit with folded sections 134. That is, when folded sections 134 bulge outward, the folded structure of cuff 132 also bulges outward, and when folded sections 134 return to their folded state, the folded structure of cuff 132 also returns to its folded state. The outward bulging of the folded structure of cuff 132 increases the cross-sectional area in the length direction.

[0073] <Air flow inside the jacket> The air flow in the air-cooled 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-cooled 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 narrow portion 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 side. The front fastener 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 lower 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 waist 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 length direction. Here, the subsequent flow of the air that has moved to the rear body 120 is the same as in the first embodiment.

[0077] The air in the region of the waist 130 in the air-cooled jacket 101 moves between the waist 132 and the body BS upward in the garment length direction and flows out from the cuff 132 (air UA). Here, the folded portion 134 in the garment length direction of the waist 130 bulges outward due to the pressure of the air sent in by the fan unit 54. This expands the air passage between the outer fabric 12 and the wearer's body BS. In addition, as the folded portion 134 of the waist 130 bulges outward, the folded structure formed in the cuff 132 connected to the folded portion 134 also expands, and the opening of the cuff 132 becomes wider. This allows more air to flow between the waist 130 and the body BS, and allows more air UA to be exhausted from the cuff 132.

[0078] [First aspect] A cooling garment 10 according to a first aspect of the present disclosure is a cooling garment 10 comprising an outer fabric 12, and a lining 40 provided on a portion of the reverse side of the outer fabric 12 and including an element mounting hole 42 for mounting a Peltier element unit 44 having a cooling plate 44a and a heat sink plate 44b on the side opposite the cooling plate 44a, in an orientation in which the cooling plate 44a faces the reverse side of the outer fabric 12, the outer fabric 12 and the lining 40 being restrained by restraining portions 24 located at two different positions in the width direction, and between the two restraining portions 24, the length of the lining 40 in the width direction is shorter than the length of the corresponding outer fabric 12 in the width direction. According to the first aspect, when the wearer puts on the cooling garment 10, tension is generated in the lining 40 in the width direction between the two restraining portions 24, while the outer fabric 12 is allowed to have slack in the width direction, so that when a Peltier element unit 44 is provided in the element mounting hole 42 of the lining 40, the cooling plate 44a of the Peltier element unit 44 can be brought into contact with the wearer's body BS.
