Background Art

[0002] In recent years, there have been many sweltering hot days that are uncomfortable for people throughout the year. On such sweltering hot days, as a measure to prevent heat stroke, in addition to small and frequent water replenishment, the use of appropriate cooling devices is encouraged. However, due to reasons such as the absence of cooling device facilities or insufficient cooling effectiveness, workers working outdoors under sweltering heat or workers working in a stuffy indoor environment, and people engaged in recreation, sports, watching games, etc. under the scorching sun cannot cool off with a cooling device. Therefore, in recent years, many body temperature adjustment clothing with a body temperature adjustment unit have been developed for people seeking to avoid the heat.

Summary of the Invention

Problems to be Solved by the Invention

[0006] Technologies such as Patent Document 1 have the following problems. The first problem is that since the flange and the annular piece of the ring body in Patent Document 1 are in the shape of a thin plate, when the fabric of the cooling clothing (body temperature regulating clothing) is pulled, the fabric sandwiched will be damaged due to the friction of the flange of the Peltier element mounting part. The second problem is that if the wearer drops the Peltier element unit (body temperature regulating device) and the flange of the Peltier element mounting part is damaged, it will be difficult to attach the Peltier element unit to the cooling clothing, which is inconvenient for the operator.

[0007] The present disclosure has been made to solve the above problems, and it is possible to prevent damage to the fabric forming the clothing with the body temperature regulating device attached, and to improve the usability of the body temperature regulating clothing. An object is to provide a body temperature regulating device and a body temperature regulating clothing equipped with the body temperature regulating device.

Means for Solving the Problems

[0008] In an aspect of the present disclosure made to solve the above problems, in a body temperature adjustment device that is detachable from an insertion hole formed in a fabric forming clothing, has a Peltier element, and has a heat exchange surface formed on the opposite side of a cooling surface or a heating surface, the body temperature adjustment device includes a main body that houses the Peltier element, and a fixing member that can be attached from an end side opposite to the cooling surface or the heating surface. The main body is composed of a small-diameter portion and a large-diameter portion. The cooling surface or the heating surface is formed on the opposite side of the small-diameter portion. The small-diameter portion has a first opening formed on the end surface of the small-diameter portion for allowing air to flow out of the main body. The large-diameter portion has a side surface portion, and a step surface is formed on the small-diameter portion side and extending radially outward about the axial center line of the main body. The side surface portion has a second opening formed on the end surface of the side surface portion for allowing air to flow into the main body. The step surface is formed from the outer peripheral end of the step surface toward the cooling surface or the heating surface. The fixing member has a sandwiching surface formed for sandwiching the step surface and the fabric.

[0009] According to this aspect, in the body temperature adjustment device, it is detachable from an insertion hole formed in the fabric forming the clothing, has a Peltier element, and a heat exchange surface is formed on the opposite side of the cooling surface or the heating surface. The body temperature adjustment device is composed of a main body that houses the Peltier element and a fixing member that can be attached from the end side opposite to the cooling surface or the heating surface. The body of the wearer is cooled or warmed by the cooling surface or the heating surface formed on the opposite side of the small-diameter portion of the main body. The large-diameter portion of the main body is on the small-diameter portion side, and a stepped surface extending radially outward around the axial center line of the main body is formed. A side surface portion formed on the large-diameter portion has a second opening for allowing air to flow into the main body and is formed from the outer peripheral end of the stepped surface toward the cooling surface or the heating surface. The fixing member has a clamping surface for clamping the stepped surface of the body temperature adjustment device and the fabric forming the clothing. Thus, even if the fabric forming the clothing is clamped between the stepped surface of the body temperature adjustment device and the clamping surface of the fixing member, since the rigidity of the main body is high, it is possible to prevent the fabric clamped by the stepped surface from being damaged. Furthermore, by clamping the fabric forming the clothing between the stepped surface of the main body portion and the clamping surface of the fixing member, the body temperature adjustment device can be attached to the fabric forming the clothing. Thereby, even if a person drops the body temperature adjustment device, it is possible to avoid a situation where the flange of the Peltier element mounting portion disclosed in Patent Document 1 is damaged and the Peltier element unit cannot be attached to the cooling clothing. Therefore, it is possible to provide a body temperature adjustment device that prevents the fabric forming the clothing to which the body temperature adjustment device is attached from being damaged and improves the usability of the body temperature adjustment clothing, and a body temperature adjustment clothing equipped with the body temperature adjustment device.

[0010] Note that the clothing according to the present disclosure is a general term for a concept including each concept of (a) upper garments such as jackets, jumpers, suits, vests, etc., (b) lower garments such as pants, trousers, etc., and (c) socks, foot warmers, etc. worn on the feet and legs, which are roughly classified.

[0011] In the above aspect, it is preferable that the fixing member has an annular flange protruding outward from the fixing member.

[0012] According to this aspect, the fixing member has an annular flange protruding outward from the fixing member, while the main body does not have a flange. Thus, even when only the fixing member has an annular flange, since the rigidity of the main body is high, it is possible to prevent the fabric sandwiched by the stepped surface from being damaged, and the body temperature adjustment device can be attached to the fabric forming the clothing.

[0013] In the above aspect, it is preferable that the heat exchange surface has cooling fins, the body temperature adjustment device is provided with a fan for sending wind to cause the air in the main body to flow out from the first opening, the main body houses the heat exchange surface in the main body, and a flow guiding member is formed around the heat exchange surface for guiding the air flowing in from the second opening toward the cooling fins along with the rotation of the fan.

[0014] According to this aspect, the air that has undergone heat exchange by contacting the cooling fins of the heat exchange surface in the main body can be made to flow out from the first opening by the fan provided in the body temperature adjustment device. The flow guiding member formed around the heat exchange surface can guide the cooling air flowing in from the second opening toward the cooling fins along with the rotation of the fan. As a result, the cooling air flowing in from the second opening is guided toward the cooling fins along with the rotation of the fan. Therefore, the cooling air in the main body can be efficiently brought into contact with the cooling fins, the air that has undergone heat exchange can be made to flow out from the first opening, and the cooling efficiency of the body temperature adjustment device can be enhanced.

[0015] In the above aspect, it is preferable that the flow guiding member extends in an arc shape toward the heat exchange surface.

[0016] According to this aspect, the flow guiding member formed around the heat exchange surface extends in an arc shape toward the heat exchange surface, so that the cooling air flowing in from the second opening can contact the flow guiding member and be guided toward the cooling fins. Thereby, the amount of cooling air flowing in from the second opening and guided to the cooling fins as the fan rotates can be increased, making it easier for the cooling air to contact the cooling fins of the heat exchange surface.

[0017] In the above aspect, it is preferable that the flow guiding member restricts the air flowing in from the second opening from staying around the heat exchange surface.

[0018] According to this aspect, the flow guiding member around the heat exchange surface can restrict the cooling air flowing in from the second opening from staying around the heat exchange surface without flowing toward the cooling fins. Thereby, it is possible to prevent the cooling air flowing in from the second opening from staying around the heat exchange surface, and further improve the cooling efficiency of the body temperature adjustment device.

[0019] In the above aspect, on the outer peripheral surface of the small diameter portion, a plurality of guide rails extending in an arc shape along the outer peripheral surface of the small diameter portion are provided between one end and the other end. The fixing member has a plurality of protrusions connectable to the plurality of guide rails. A plurality of restricting portions for restricting the movement operation of the protrusions are intermittently provided on a sliding surface connecting the one end and the other end of each of the plurality of guide rails. The plurality of restricting portions include a first restricting portion and a second restricting portion provided on the other end side of the first restricting portion. A plurality of gaps extending in the axial direction of the main body are provided between the plurality of guide rails. The body temperature adjustment device is attached to the fabric by causing each protrusion constituting the plurality of protrusions to enter the gaps constituting the plurality of gaps in the axial direction of the main body, sandwiching the fabric between the main body and the fixing member, relatively rotating the main body and the fixing member, and engaging each protrusion constituting the plurality of protrusions with the first restricting portion or the second restricting portion in a state where the fabric is sandwiched between the main body and the fixing member. This is preferably done.

[0020] According to this aspect, when attaching the body temperature adjustment device to the fabric forming the clothing, a person inserts each of the protrusions forming a plurality of protrusions into each interval forming a plurality of gaps in the axial direction of the main body, and sandwiches the fabric with the main body and the fixing member. Subsequently, when the person relatively rotates the main body and the fixing member, and each of the plurality of protrusions of the fixing member overrides each of the plurality of regulating portions while the fabric is sandwiched between the main body and the fixing member, the moving operation is regulated by the regulating portion, and the regulating portion and the protrusion engage with each other. Thereby, a person can attach the body temperature adjustment device to the fabric forming the clothing with a one-touch operation with a sense of moderation. Therefore, since poor tightening or loosening of the fixing member does not occur, it is possible to avoid the body temperature adjustment device falling off from the clothing or only the fixing member being lost.

[0021] In the above aspect, it is preferable that each of the plurality of guide rails is formed in an inclined manner with a height difference in the axial direction of the main body between the one end and the other end.

[0022] According to this aspect, when the fabric forming the clothing is thick, each of the protrusions forming a plurality of protrusions is engaged with the first regulating portion while the fabric is sandwiched between the main body and the fixing member. On the other hand, when the fabric forming the clothing is not thick, each of the protrusions forming a plurality of protrusions is engaged with the second regulating portion while the fabric is sandwiched between the main body and the fixing member. Thereby, the body temperature adjustment device can be attached in a state where the fabric is firmly sandwiched between the main body and the fixing member so that the body temperature adjustment device does not fall off from the body temperature adjustment clothing corresponding to the thickness of any fabric forming the clothing. Further, even when each of the protrusions forming a plurality of protrusions is engaged with the first regulating portion or the second regulating portion while the fabric forming the clothing is sandwiched between the main body and the fixing member, the fabric around the insertion hole is difficult to plastically deform. Therefore, it is possible to prevent the body temperature adjustment device sandwiched in the fabric from rattling or the fabric from being damaged.

[0023] It is preferable that the body temperature adjustment clothing is formed by detachably attaching the body temperature adjustment device according to the above aspect to the clothing.

[0024] According to this aspect, it is possible to prevent damage to the fabric forming the clothing to which the body temperature adjustment device according to the present disclosure is attached, and to provide a user-friendly body temperature adjustment clothing in which the body temperature adjustment device can be inserted into the insertion hole of the fabric forming the body temperature adjustment clothing and the body temperature adjustment device can be worn.

Effect of the Invention

[0025] Therefore, according to the present disclosure, there is an excellent effect of being able to prevent damage to the fabric forming the clothing to which the body temperature adjustment device is attached and to improve the ease of use of the body temperature adjustment clothing, and to provide a body temperature adjustment device and a body temperature adjustment clothing formed by wearing the body temperature adjustment device.

FIG. 8 is an explanatory view showing a method of mounting the blowing unit according to the first embodiment on the temperature control vest. FIG. 9 is a partial cross-sectional view of the blowing unit mounted on the temperature control vest according to the first embodiment.

[0041] The blowing unit 40 is mounted on the temperature control vest 1 so that it can blow air to the body, either cold air in a state lower than the outside air or warm air in a state higher than the outside air, by the rotation of the fan 42. As shown in FIGS. 5 to 7, the blowing unit 40 of the first embodiment is roughly composed of a main body portion 41 and a pressing member 110. The main body portion 41 includes a fan 42 that blows air, a driving unit 43 for the blowing unit that controls the rotation of the fan 42 with a motor (not shown), and a casing 44 that covers the periphery of the fan 42 and the driving unit 43 for the blowing unit so as to allow ventilation. The fan 42 of the first embodiment is, for example, a propeller-type fan having a propeller.

[0042] The blower unit 40 requires a portable battery 84, which is a storage battery such as a primary battery or a secondary battery, as the power source for the motor of the driving unit 43 for the blower unit. In the temperature control vest 1, the portable battery 84 is housed in the first storage unit 6 or the like. The portable battery 84 according to the first embodiment is a general-purpose power source configured with specifications such as an output of 5V (volts) and a battery capacity of 5200 mA.

[0043] As shown in FIGS. 1 to 4, the blower unit 40 is electrically connected to the portable battery 84 via the blower operation unit 80 by the blower wiring 85. When the driving unit 43 for the blower unit is in conduction with the portable battery 84 via the blower operation unit 80, the fan 42 rotates. Thereby, the wind accompanying the rotation of the fan 42 is sent toward the body surface BS side (body side) of the wearer HM toward the body side (see FIG. 9).

[0044] As shown in FIGS. 5 to 7, the casing 44 is composed of an outer case portion 46 and an inner case portion 45. The outer case portion 46 covers the fan 42 across its radial direction RD on the lower side Lw in the axial direction L along the axis line AX of the fan 42, which is the side where the fan 42 blows air by rotation. The outer case portion 46 has a plurality of air holes 46a for taking in either cold air in a state lower in temperature than the outside air or warm air in a state higher in temperature than the outside air. The inner case portion 45 covers the driving unit 43 for the blower unit on the Lw side in a state of being connected to the driving unit 43 for the blower unit. A plurality of discharge ports 45a for sending air from the outside of the blower unit 40 are formed in the inner case portion 45. In the casing 44 according to the first embodiment, the inner case portion 45 is provided on a cylindrical inner case peripheral wall portion 49 that covers the outer peripheral side of the fan 42 and a part of the outer peripheral side of the driving unit 43 for the blower unit on the Lw side. A male screw 48 is formed on the outer periphery of the inner case peripheral wall portion 49.

[0045] The outer case part 46 and the inner case part 45 are integrally connected via the inner case peripheral wall part 49. Specifically, the outer case part 46 is connected to the inner case part 45 at the upper side Lp of the inner case peripheral wall part 49. An annular flange 47 surrounding the outer case part 46 is formed around the outer case part 46.

[0046] As shown in FIG. 7, the pressing member 110 according to the first embodiment is a cylindrical and thin-walled member having a pressing part 111 that can be arranged at a position facing the flange 47 at the tip position on the Lp side. On the inner periphery of the pressing member 110, a female screw 112 that can be screwed with the male screw 48 of the inner case peripheral wall part 49 is formed. On the outer periphery of the pressing member 110, anti-slip protrusions are intermittently provided. When screwing the male screw 48 of the inner case peripheral wall part 49 of the main body part 41 and the female screw 112 of the pressing member 110 together, the pressing member 110 is firmly gripped by these protrusions and is easy to rotate. Here, screwing means fitting the screws together (see the Glossary of Patent Technical Terms (Nikkankogyo Shimbunsha)). Here, a screw is something having a spiral groove or protrusion for fastening an object (Kodansha Encyclopedia Sixth Edition). That is, screwing means fitting mutually opposing spiral screws or the like together to fasten an object.

[0047] <Regarding the installation of the blower unit 40 of the first embodiment> In the installation of the blower unit 40 according to the first embodiment, as shown in FIG. 8, first, the lower side Lw of the main body 41 is inserted from the outside 20a of the fan mounting portion 20 into the fan insertion hole 22 formed in the fan mounting portion 20 and the insertion hole 3b of the back fabric 3B. With the flange 47 in contact with the outer peripheral edge portion 21 of the fan of the fan mounting portion 20, the outer case portion 46 is disposed in the fan insertion hole 22 and the insertion hole 3b of the back fabric 3B. Next, a person places the pressing member 110 near the outer peripheral edge portion 21 of the fan from the side of the lining 11 of the temperature control vest 1, and the main body 41 and the pressing member 110 are relatively rotated and assembled. Then, the person screws and fixes the male screw 48 of the main body 41 and the female screw 112 of the pressing member 110, and the outer peripheral edge portion 21 of the fan and the back fabric 3B are sandwiched by the flange 47 and the pressing portion 111. The main body 41 and the pressing member 110 are fixed to the fabric 3 in a state where the outer peripheral edge portion 21 of the fan and the back fabric 3B are sandwiched by the flange 47 and the pressing portion 111. Thus, as shown in FIGS. 1, 2, 4, and 9, the blower unit 40 is fixed to the fabric 3.

[0048] The portable battery 84 and the blower wiring 85 are detachably attached to each other through a connector such as a USB (Universal Serial Bus) connection. The power of the portable battery 84 is supplied to the drive unit 43 for the blower unit and the motor of the drive unit 43 for the blower unit through the blower wiring 85.

[0049] When a voltage of 5V is supplied through the blower wiring 85, the drive unit 33 is driven under the control of the blower control unit 81, and the propeller-type fan 42 is rotated. Along with the rotation of the propeller-type fan 42, the air outside the temperature control vest 1 is taken in from the back surface of the main body of the blower unit 40 shown in FIG. 6, and the air is blown out from the front surface of the main body of the blower unit 40 shown in FIG. 5. As shown in FIGS. 1 to 4, the blower unit 40 is electrically connected to the portable battery 84 through the blower operation unit 80 by the blower wiring 85.

[0050] <Regarding the Peltier element unit 60 of the first embodiment> Next, the Peltier element unit 60 will be described with reference to FIGS. 10 to 13. FIG. 10 is an explanatory view showing the temperature control vest according to the first embodiment from the emission surface side with the Peltier element unit. FIG. 11 is an explanatory view showing the temperature control vest 1 according to the first embodiment from the heat dissipation surface side with the Peltier element unit. FIG. 12 is an exploded perspective view showing the configuration of the Peltier element unit according to the first embodiment. FIG. 13 is a developed view of the outer peripheral surface of the main body portion according to the first embodiment developed on a plane.

[0051] As shown in FIGS. 10 to 11, the Peltier element unit 60 has a Peltier element PE incorporated in a cover member. The Peltier element is a type of plate-shaped semiconductor thermoelectric element. When a direct current is supplied to the Peltier element PE, in the flat plate portion of the Peltier element PE, due to the Peltier effect, one surface, for example, absorbs heat to about 10 ° C. and enters a state of heat absorption (cooling surface), and at the same time, the other surface on the opposite side generates heat to about 30-odd ° C. and enters a state of heat generation (heating surface). The Peltier element is an element that transfers the heat of the cooling surface to the heating surface side and generates a large amount of heat on the heating surface side. The Peltier element unit 60 is configured to be able to transfer heat to the body either the cold heat presented on the cooling surface that has become under heat absorption or the warm heat presented on the heating surface that has become under heat generation simultaneously with heat absorption on the opposite side of the cooling surface by the energized Peltier element PE.

[0052] As shown in FIGS. 10 to 12, the Peltier element unit 60 has a heat dissipation surface 61 on one side thereof, a main body portion 62 formed in a cylindrical shape, and an air hole 64a for allowing air in the temperature control vest 1 to flow in, and an air cylinder portion 64 formed in a cylindrical shape. Four air holes 64a are formed in the circumference of the air cylinder portion 64. As shown in FIGS. 10 to 11, the main body portion 62 has a discharge surface 62a. The Peltier element unit 60 also has a heat exchange surface 65 that takes in heat by the Peltier element PE and dissipates it into the air for heat exchange. A discharge portion 62b for discharging the air heat-exchanged by the heat exchange surface 65 to the outside of the Peltier element unit 60 is formed on the discharge surface 62a. Further, the Peltier element unit 60 also has a blower device 100 that blows the air heat-exchanged by the heat exchange surface 65 to the discharge portion 62b, an inner flange 63 formed on the cover member of the main body portion 62, a ring fastener 120, and the like.

[0053] As shown in FIG. 12, a guide rail 66 is provided on the outer peripheral surface of the main body portion 62. The guide rail 66 extends toward the discharge portion 62b side and is arc-shaped along the circumferential direction CR of the main body portion 62 between one end 66a and the other end 66b (see FIGS. 13 and 15). A plurality (for example, 4) of guide rails 66 are provided at different positions in the circumferential direction CR of the main body portion 62. Mounting groove portions 69 are respectively provided between the plurality of guide rails 66 and the inner flange 63. The plurality (for example, 4) of mounting groove portions 69 are provided along the circumferential direction CR of the main body portion 62. The guide rails 66 adjacent to each other in the circumferential direction CR are arranged at the same height in the axial direction L (see FIGS. 15 to 17). The four guide rails 66 are respectively provided with a gap 70 between the intermittently adjacent guide rails 66. A plurality (for example, 4) of gaps 70 are provided on the outer peripheral surface of the main body portion 62. As shown in FIG. 12, the gap 70 is connected to the mounting groove portion 69.

[0054] As shown in FIG. 13, a plurality of guide rails 66 connect between one end 66a and the other end 66b of each guide rail 66, and have sliding surfaces 68 that contact respective protrusions 122 of the ring fastener 120. As shown in FIGS. 12 and 13, a plurality (for example, 4) of restricting portions 67 are provided on each of the sliding surfaces 68 of the plurality of guide rails 66. Each of the plurality of restricting portions 67 restricts the movement of the plurality of protrusions 122 that move along the sliding surface 68 in the anti-circular direction ACR of the main body portion 62. On the sliding surface 68 connecting one end 66a and the other end 66b of each guide rail 66, the restricting portions 67 are intermittently arranged in the order of the first restricting portion 67a ⇒ the second restricting portion 67b ⇒ the third restricting portion 67c ⇒ the fourth restricting portion 67d. Each of the plurality of fourth restricting portions 67d is configured to have a height that the respective plurality of protrusions 122 cannot overcome.

[0055] Next, with reference to FIG. 13, a plurality of guide rails 66 provided on the outer peripheral surface of the main body portion 62 developed on a plane will be described. As shown in FIG. 13, the plurality of guide rails 66 are inclined toward the air cylinder portion 64 having the air holes 64a with respect to a plane parallel to the axial direction L along the axial center line AX of the main body portion 62. All of the plurality of guide rails 66 in the first embodiment are given an inclination angle θ of 3° as an example between one end 66a and the other end 66b. Thereby, all of the plurality of guide rails 66 in the first embodiment are formed in an inclined manner with a height difference ΔH in the axial direction L between one end 66a and the other end 66b. That is, the inclination angle θ of the sliding surface 68 according to the first embodiment is 3° toward the air cylinder portion 64 having the air holes 64a with respect to a plane parallel to the axial direction L along the axial center line AX of the main body portion 62.

[0056] The ring fastener 120 is formed so as to be freely fastened or released at the end opposite to the heat dissipation surface 61 (cooling surface 61A, heating surface 61B). The ring fastener 120 is made of synthetic resin and has an annular outer flange 121 formed in a substantially polygonal shape. As shown in FIG. 12, the outer flange 121 has 12 elliptical through holes formed therein. The inner diameter of the ring fastener 120 is larger than the outer diameter of the discharge surface 62a and smaller than the outer diameter of the inner flange 63.

[0057] Protrusions 122 that can be connected to each of the plurality of guide rails 66 are disposed on the inner peripheral surface 120a of the ring fastener 120. A plurality (for example, four) of protrusions 122 are provided at intervals in the circumferential direction CR of the ring fastener 120. Each of the plurality of protrusions 122 can engage with each of the plurality of restricting portions 67 of the plurality of guide rails 66. The protrusions 122 adjacent to each other in the circumferential direction CR are disposed at the same height in the axial direction L. Each of the plurality of protrusions 122 is formed so as to be able to pass through each of the plurality of gaps 70. One protrusion 122 engages with one guide rail 66 through the gap 70. The plurality of protrusions 122 are inclined toward the surface 121a with respect to a plane parallel to the surface 121a of the outer flange 121, and the inclination angle θ is 3°. Thereby, each of the plurality of protrusions 122 is easily connected to each of the plurality of guide rails 66. In the temperature control vest 1, the three Peltier element units 60 (first Peltier element unit 60A, second Peltier element unit 60B, third Peltier element unit 60C) are mounted on three element mounting portions 30 in the vest body 2.

[0058] The heat dissipation surface 61 is in a state of being exposed to the outside, and in the Peltier element unit 60 (Peltier element unit), the heat dissipation surface 61 and the discharge surface 62a are arranged on opposite sides of each other. Here, the heat dissipation surface 61 is made of, for example, a metal excellent in stainless steel, thermal conductivity, etc.

[0059] The heat exchange surface 65 formed on the back side of the heat dissipation surface 61 is made of a metal such as aluminum or copper, which is excellent in thermal conductivity and the like. The heat exchange surface 65 has a plurality (for example, 117) of cooling fins 65a configured in a protruding shape. Since the cooling fins 65a are configured in a protruding shape, the portion in contact with the air is enlarged due to the expansion of the surface area of the cooling fins 65a, and the heat of the Peltier element can be efficiently released. In the heat exchange surface 65, the cooling fins 65a are arranged in alignment with a certain interval so that the air flowing in from the air holes 64a can pass between the cooling fins 65a. Thereby, the cooling air flowing in between the cooling fins 65a comes into contact with the cooling fins 65a, so that the heat of the Peltier element PE can be efficiently exchanged.

[0060] As shown in FIG. 12, a heat dissipation surface 61 (cooling surface 61A, heating surface 61B) is provided at an end portion on the side opposite to the main body portion 62 in the axial direction L along the axial center line AX of the main body portion 62. The main body portion 62 is formed in a cylindrical shape and is provided with an inner flange 63 that projects in an annular plate shape from the outer peripheral end portion.

[0061] As shown in FIG. 12, the air blower 100 according to the first embodiment includes an exhaust heat fan 101 that blows air and an exhaust heat fan drive unit 102 that is controlled by a motor (not shown) that rotates the exhaust heat fan 101. Thereby, the air heat-exchanged by the heat exchange surface 65 is discharged from the discharge portion 62b by the wind generated by the rotation of the exhaust heat fan 101 due to the drive of the exhaust heat fan drive unit 102 under the control of the temperature control unit 91.

[0062] In the Peltier element unit 60, as shown in FIGS. 1, 2, and 4, the Peltier element PE is electrically connected to the portable battery 84 via the temperature control wiring 95 and the temperature control operation unit 90.

[0063] For example, when three Peltier element units 60 are attached to the temperature control vest 1, the temperature control wiring 95 is in the form of three temperature control branch lines 96A, 96B, and 96C that are split from the main temperature control line 96 bundled in a single strip at the temperature control branch section 97 and extend. That is, the number of the temperature control branch lines 96A, 96B, 96C, etc. matches the number of the Peltier element units 60.

[0064] The main temperature control line 96 of the temperature control wiring 95 is connected to the portable battery 84. For example, the temperature control branch line 96A is connected to the first Peltier element unit 60A. For example, the temperature control branch line 96B is connected to the second Peltier element unit 60B. For example, the temperature control branch line 96C is connected to the third Peltier element unit 60C. However, it is not limited thereto. As long as the temperature control branch lines 96A, 96B, and 96C have a one-to-one connection relationship with the three Peltier element units 60 (the first to third Peltier element units 60A, 60B, 60C), they may be arbitrarily connected under the judgment of the wearer HM by simplifying the wiring path particularly.

[0065] <Regarding the attachment of the Peltier element unit 60 of the first embodiment> The attachment of the Peltier element unit 60 will be described with reference to FIG. 14. FIG. 14 is an explanatory diagram showing a method of attaching the Peltier element unit according to the first embodiment to the temperature control vest.

[0066] A method of attaching the Peltier element unit 60 to the element mounting portion 30 will be described with reference to FIG. 14. As shown in FIG. 14, in the attachment of the Peltier element unit 60, the emission surface 62a side of the main body portion 62 of the Peltier element unit 60 is inserted from the inner side 30a of the element mounting portion 30 into the element insertion hole 32 formed in the element mounting portion 30 and into the insertion hole 3b of the back fabric 3B. The Peltier element unit 60 is arranged in the element insertion hole 32 and in the insertion hole 3b of the back fabric 3B with the inner flange 63 in contact with the outer peripheral edge portion 31 of the element. The element insertion hole 32 is a hole for attaching the heat dissipation surface 61 (cooling surface 61A or heating surface 61B) of the Peltier element unit 60 in close contact with the body of the wearer HM of the temperature control vest 1.

[0067] Subsequently, the outer flange 121 is brought into contact with the back fabric 3B from the outside of the back fabric 3B. A person enters the main body 62 inside the ring fastener 120 and inserts each of the plurality of protrusions 122 of the ring fastener 120 into each of the plurality of gaps 70. As a result, the back fabric 3B and the element outer peripheral edge portion 31 are in a state of being sandwiched between the inner flange 63 of the main body 62 and the outer flange 121 of the ring fastener 120. Subsequently, the person relatively rotates the main body 62 and the ring fastener 120 in the circumferential direction CR of the main body 62, so that each protrusion 122 enters the attachment groove portion 69 from one end 66a of the guide rail 66. Further, the person relatively rotates the main body 62 and the ring fastener 120 in the circumferential direction CR of the main body 62, so that each protrusion 122 slides on the sliding surface 68 of each guide rail 66 along the circumferential direction CR of the main body 62. Subsequently, the person relatively rotates the main body 62 and the ring fastener 120 in the circumferential direction CR of the main body 62, and causes the plurality of protrusions 122 to overcome the restricting portions 67 provided on each of the plurality of sliding surfaces 68. When each of the plurality of protrusions 122 has overcome each of the plurality of restricting portions 67, the plurality of restricting portions 67 restrict the movement of the plurality of protrusions 122 in the anti-circumferential direction ACR of the main body 62. The protrusion 122 that has overcome the restricting portion 67 and stopped moving comes into surface contact with the restricting portion 67 and engages therewith to be fixed. As a result, the back fabric 3B and the element outer peripheral edge portion 31 are fixed in a state of being sandwiched between the inner flange 63 and the outer flange 121. The plurality of protrusions 122 according to the first embodiment and the restricting portions 67 of the guide rail 66 can be connected, but do not hit each other such as helical screws that oppose each other. Therefore, the protrusion 122 of the ring fastener 120 and the restricting portion 67 of the guide rail 66 are fixed by engagement, and are not fixed by screwing.

[0068] The first Peltier element unit 60A is mounted on the element mounting portion 30 of the first rib portion 18. In this case, the heat dissipation surface 61 (cooling surface 61A or heating surface 61B) is in a state where it can be opposed to and in contact with the body side (neck muscle) of the wearer HM of the temperature control vest 1 itself (see FIGS. 18 and 22). Thereby, the heat dissipation surface 61 (cooling surface 61A or heating surface 61B) can be brought into direct or indirect contact with the body surface of the wearer HM itself via a singlet or the like, and the neck muscle of the wearer can be cooled.

[0069] The Peltier element units 60 (second Peltier element unit 60B, third Peltier element unit 60C) are mounted on the element mounting portion 30 near the sleeve loop portions 10 (first sleeve loop portion 10A, second sleeve loop portion 10B). In this case, the heat dissipation surface 61 (cooling surface 61A or heating surface 61B) is in a state where it can be opposed to and in contact with the body side (near the armpit) of the wearer HM of the temperature control vest 1 itself (see FIGS. 18 and 22). Thereby, the heat dissipation surface 61 (cooling surface 61A or heating surface 61B) can be brought into direct or indirect contact with the body surface of the wearer HM itself via a singlet or the like, and the armpit can be cooled.

[0070] <Regarding the thickness of the fabric sandwiched between the inner flange 63 and the outer flange 121> Using FIGS. 15 to 17, the location where the protrusion 122 and the sliding surface 68 are engaged and fixed according to the thickness of the fabric sandwiched between the inner flange 63 and the outer flange 121 will be described. FIG. 15 is a side view of the Peltier element unit according to the first embodiment, and is an explanatory diagram showing the case where the inner flange and the outer flange are engaged at the first stage. FIG. 16 is a side view of the Peltier element unit according to the first embodiment, and is an explanatory diagram showing the case where the inner flange and the outer flange are engaged at the second stage. FIG. 17 is a side view of the Peltier element unit according to the first embodiment, and is an explanatory diagram showing the case where the inner flange and the outer flange are engaged at the third stage.

[0071] Using FIG. 15, a case will be described where each of the plurality of protrusions 122 overrides the first regulating portion 67a of each guide rail 66 and the guide rail 66 engages with the protrusion 122 in the first stage. When the thickness of the fabric made of the temperature control vest 1 is X1 (for example, about 3 mm), a person enters the main body portion 62 inside the ring fastener 120 with the fabric sandwiched between the inner flange 63 and the outer flange 121. As a result, each of the plurality of protrusions 122 enters each of the plurality of gaps 70. Subsequently, when the person relatively rotates the main body portion 62 and the ring fastener 120 in the circumferential direction CR of the main body portion 62, each protrusion 122 of the ring fastener 120 enters the attachment groove portion 69 from one end 66a of the guide rail 66. Further, when the person relatively rotates the main body portion 62 and the ring fastener 120 in the circumferential direction CR of the main body portion 62, each of the plurality of protrusions 122 slides on the sliding surface 68 of each guide rail 66 along the circumferential direction CR of the main body portion 62. When the main body portion 62 and the ring fastener 120 are relatively rotated by, for example, 15 degrees along the circumferential direction CR of the main body portion 62, each of the plurality of protrusions 122 overrides each of the plurality of first regulating portions 67a disposed on the sliding surface 68. The movement of each protrusion 122 in the anti-circumferential direction ACR is regulated by each overridden first regulating portion 67a. The angle by which the main body portion 62 and the ring fastener 120 are relatively rotated along the circumferential direction CR of the main body portion 62 for each of the plurality of protrusions 122 to override each of the plurality of first regulating portions 67a is not limited to 15 degrees. For example, it is preferably any angle between 15 degrees and 20 degrees.

[0072] As shown in FIG. 15, each of the plurality of protrusions 122 that has stopped moving in the circumferential direction CR of the main body 62 at the first stage is fixed by surface contact and engagement with each of the plurality of first restricting portions 67a. In this case, the Peltier element unit 60 can be attached to the temperature control vest 1 in a state where a fabric having a thickness of X1 (for example, about 3 mm) that forms the temperature control vest 1 is sandwiched between the inner flange 63 and the outer flange 121. When releasing the attachment of the Peltier element unit 60, a person relatively rotates the main body 62 and the ring fastener 120 by, for example, 15 degrees in the anti-circumferential direction ACR of the main body 62, so that each of the plurality of protrusions 122 gets over each of the first restricting portions 67a. Thereby, the Peltier element unit 60 can be detached from the temperature control vest 1.

[0073] Next, with reference to FIG. 16, the case where each of the plurality of protrusions 122 gets over the second restricting portion 67b of each guide rail 66 and the guide rail 66 and the protrusion 122 engage with each other at the second stage will be described. When the thickness of the fabric that forms the temperature control vest 1 is X2 (for example, about 2 mm), a person enters the main body 62 inside the ring fastener 120 in a state where the fabric is sandwiched between the inner flange 63 and the outer flange 121. Thereby, each of the protrusions 122 enters each of the gaps 70. Subsequently, when a person relatively rotates the main body 62 and the ring fastener 120 in the circumferential direction CR of the main body 62, each of the protrusions 122 of the ring fastener 120 enters the attachment groove portion 69 from one end 66a of the guide rail 66. Further, when a person relatively rotates the main body 62 and the ring fastener 120 in the circumferential direction CR of the main body 62, each of the plurality of protrusions 122 slides on the sliding surface 68 of each guide rail 66 along the circumferential direction CR of the main body 62. When the main body 62 and the ring fastener 120 are relatively rotated by, for example, 15 degrees along the circumferential direction CR of the main body 62, each of the plurality of protrusions 122 gets over each of the plurality of first restricting portions 67a arranged on the sliding surface 68. The movement of each of the protrusions 122 in the anti-circumferential direction ACR is restricted by each of the first restricting portions 67a that has been got over.

[0074] Furthermore, when a person rotates the main body portion 62 and the ring fastener 120 relative to each other by, for example, 15 degrees along the circumferential direction CR of the main body portion 62, each of the plurality of protrusions 122 slides on the sliding surface 68 and overrides each of the plurality of second restricting portions 67b. The movement of each of the protrusions 122 in the anti-circumferential direction ACR is restricted by each of the overridden second restricting portions 67b. The angle by which the main body portion 62 and the ring fastener 120 are relatively rotated along the circumferential direction CR of the main body portion 62 for each of the plurality of protrusions 122 to override each of the plurality of second restricting portions 67b is not limited to 15 degrees. For example, it is preferably any angle between 15 degrees and 20 degrees.

[0075] As shown in FIG. 16, each of the plurality of protrusions 122 that has stopped moving in the circumferential direction CR of the main body portion 62 at the second stage is fixed by surface contact and engagement with each of the plurality of second restricting portions 67b. In this case, the Peltier element unit 60 can be attached to the temperature control vest 1 with a fabric having a thickness of X2 (for example, about 2 mm) of the fabric forming the temperature control vest 1 sandwiched between the inner flange 63 and the outer flange 121. When removing the attachment of the Peltier element unit 60, a person relatively rotates the main body portion 62 and the ring fastener 120 by, for example, 30 degrees in the anti-circumferential direction ACR of the main body portion 62, so that each of the plurality of protrusions 122 overrides each of the first restricting portion 67a and the second restricting portion 67b. Thereby, the Peltier element unit 60 can be detached from the temperature control vest 1.

[0076] Next, with reference to FIG. 17, a case will be described in which each of the plurality of protrusions 122 overrides the third regulating portion 67c of each guide rail 66 and the guide rail 66 engages with the protrusion 122 at the third stage. When the thickness of the fabric forming the temperature control vest 1 is X3 (for example, about 1 mm), with the fabric sandwiched between the inner flange 63 and the outer flange 121, a person enters the main body portion 62 inside the ring fastener 120. As a result, each of the protrusions 122 enters each of the gaps 70. Subsequently, when the person relatively rotates the main body portion 62 and the ring fastener 120 in the circumferential direction CR of the main body portion 62, each of the protrusions 122 of the ring fastener 120 enters the attachment groove portion 69 from one end 66a of the guide rail 66. Further, when the person relatively rotates the main body portion 62 and the ring fastener 120 in the circumferential direction CR of the main body portion 62, each of the plurality of protrusions 122 slides on the sliding surface 68 of each guide rail 66 along the circumferential direction CR of the main body portion 62. When the main body portion 62 and the ring fastener 120 are relatively rotated by, for example, 15 degrees along the circumferential direction CR of the main body portion 62, each of the plurality of protrusions 122 overrides each of the plurality of first regulating portions 67a disposed on the sliding surface 68. The movement of each protrusion 122 in the anti-circumferential direction ACR is regulated by each of the overridden first regulating portions 67a.

[0077] Furthermore, when the person relatively rotates the main body portion 62 and the ring fastener 120 by, for example, 15 degrees along the circumferential direction CR of the main body portion 62, each of the plurality of protrusions 122 slides on the sliding surface 68 and overrides each of the plurality of second regulating portions 67b. The movement of each protrusion 122 in the anti-circumferential direction ACR is regulated by each of the overridden second regulating portions 67b.

[0078] Furthermore, when a person relatively rotates the main body portion 62 and the ring fastener 120 along the circumferential direction CR of the main body portion 62, for example, by 15 degrees, each of the plurality of protrusions 122 slides on the sliding surface 68 and crosses each of the plurality of third restricting portions 67c. The movement of each of the protrusions 122 in the anti-circumferential direction ACR is restricted by each of the crossed third restricting portions 67c. The angle by which the main body portion 62 and the ring fastener 120 are relatively rotated along the circumferential direction CR of the main body portion 62 for each of the plurality of protrusions 122 to cross each of the plurality of third restricting portions 67c is not limited to 15 degrees. For example, it is preferably either 15 degrees or 20 degrees.

[0079] As shown in FIG. 17, each of the plurality of protrusions 122 that has stopped moving in the circumferential direction CR of the main body portion 62 at the third stage comes into surface contact and engages with each of the plurality of third restricting portions 67c, thereby fixing. In this case, the Peltier element unit 60 can be attached to the temperature control vest 1 in a state where a fabric having a thickness of X3 (for example, about 1 mm) of the fabric forming the temperature control vest 1 is sandwiched between the inner flange 63 and the outer flange 121. When removing the attachment of the Peltier element unit 60, a person relatively rotates the main body portion 62 and the ring fastener 120 by, for example, 45 degrees in the anti-circumferential direction ACR of the main body portion 62, so that each of the plurality of protrusions 122 crosses each of the first restricting portion 67a to the third restricting portion 67c. Thereby, the Peltier element unit 60 can be detached from the temperature control vest 1.

[0080] When each of the plurality of protrusions 122 crosses the third restricting portion 67c, even if a person relatively rotates the main body portion 62 and the ring fastener 120 in the circumferential direction CR of the main body portion 62, each of the plurality of protrusions 122 cannot cross each of the plurality of fourth restricting portions 67d. Thereby, it is possible to prevent the Peltier element unit 60 from falling off the temperature control vest 1 due to the relative rotation of the main body portion 62 and the ring fastener 120 in the circumferential direction of the main body portion 62.

[0081] When attaching the Peltier element unit 60 according to the first embodiment to the best body 2, first, each of the plurality (for example, 4) of protrusions 122 that make up the protrusions enters the plurality (for example, 4) of gaps 70 in the axial direction L along the axial center line AX of the main body portion 62. As a result, the inner flange 63 and the ring fastener 120 sandwich the fabric of the temperature control vest 1. Subsequently, the main body portion 62 and the ring fastener 120 are relatively rotated, and in a state where the inner flange 63 and the ring fastener 120 sandwich the fabric of the temperature control vest 1, each of the plurality of protrusions 122 has its movement restricted by each of the overridden restricting portions 67. Further, by each of the plurality of protrusions 122 engaging with each of the restricting portions 67, the Peltier element unit 60 is attached to the temperature control vest 1 in a state where the inner flange 63 and the ring fastener 120 sandwich the fabric of the temperature control vest 1. Therefore, a person can attach the Peltier element unit 60 to the temperature control vest 1 with a one-touch operation. Further, when the main body portion 62 and the ring fastener 120 are relatively rotated, the engagement positions with each of the plurality of protrusions 122 can be changed step by step. As a result, if the thickness of the fabric of the temperature control vest 1 is about 3 mm, each of the plurality of protrusions 122 engages with each of the plurality of first restricting portions 67a, and the Peltier element unit 60 can be attached to the temperature control vest 1. If the thickness of the fabric of the temperature control vest 1 is about 2 mm, each of the plurality of protrusions 122 engages with each of the second restricting portions 67b, and the Peltier element unit 60 can be attached to the temperature control vest 1. If the thickness of the fabric of the temperature control vest 1 is about 1 mm, each of the plurality of protrusions 122 engages with each of the third restricting portions 67c, and the Peltier element unit 60 can be attached to the temperature control vest 1. Therefore, regardless of the thickness of the fabric of the temperature control vest 1, a person can attach the Peltier element unit 60 to the temperature control vest 1 corresponding to that thickness. Therefore, it becomes easy to attach the Peltier element unit 60 according to the first embodiment to the fabric of the temperature control vest 1, and the usability of the temperature control vest 1 can be improved. Further, even if the back fabric 3B and the element mounting portion 30 are sandwiched many times between the inner flange 63 and the ring fastener 120, it is possible to make it difficult for the back fabric 3B and the element mounting portion 30 to plastically deform.Therefore, even if the Peltier element unit 60 is attached to the temperature control vest 1, it is possible to prevent rattling and damage to the back fabric 3B and the element mounting portion 30.

[0082] <Regarding the inclination angle of the flange> With reference to FIGS. 18 to 19, the inclination angles of the inner flange 63 and the outer flange 121 will be described. FIG. 18 is a partial cross-sectional view of the Peltier element unit mounted on the element mounting portion. FIG. 19 is an enlarged cross-sectional view of the inner flange and the outer flange shown in FIG. 18. FIGS. 18 and 19 are drawings showing a state in which the Peltier element unit 60 (the first Peltier element unit 60A, the second Peltier element unit 60B, the third Peltier element unit 60C) is mounted on the element mounting portion 30.

[0083] As shown in FIGS. 18 and 19, the surface 63a of the inner flange 63 and the surface 121a of the outer flange 121 of the Peltier element unit 60 are in contact with, that is, in surface contact with, the element mounting portion 30. The surface contact between the surface 63a of the inner flange 63 and the surface 121a of the outer flange 121 can prevent the Peltier element unit 60 from coming off the element mounting portion 30.

[0084] As shown in FIG. 19, the back surface 63b of the inner flange 63 and the back surface 121b of the outer flange 121 are not in contact with the element mounting portion 30.

[0085] As shown in FIGS. 18 and 19, the surface 63a and the back surface 63b of the inner flange 63 are inclined toward the discharge portion 62b formed on the discharge surface 62a with respect to a plane parallel to the heat dissipation surface 61 (the cooling surface 61A or the heating surface 61B). The inclination angle θ of the surface 63a and the back surface 63b of the inner flange 63 in the first embodiment is 20°.

[0086] As shown in FIGS. 18 and 19, the front surface 121a and the back surface 121b of the outer flange 121 are inclined toward the discharge portion 62b formed on the discharge surface 62a with respect to the surface parallel to the heat dissipation surface 61 (cooling surface 61A or heating surface 61B), similar to the inner flange 63. Note that the inclination angle θ of the front surface 121a and the back surface 121b of the outer flange 121 in the first embodiment is 20°.

[0087] <Function of changing the air flow of the flange> The inclination angle θ of the front surface 63a and the back surface 63b of the inner flange 63 of the Peltier element unit 60 in the first embodiment is 20° with respect to the heat dissipation surface 61 (cooling surface 61A or heating surface 61B). Thereby, the inner flange 63 of the Peltier element unit 60 has a function of changing the flow of the air flowing into the air holes 64a of the Peltier element unit 60 downward. With reference to FIGS. 20 to 21, the function of changing the flow of the air flowing into the air holes 64a of the Peltier element unit 60, which the inner flange 63 of the Peltier element unit 60 in the first embodiment has, will be described.

[0088] FIG. 20A is an explanatory diagram showing the air flow flowing into the air holes of the comparative example. FIG. 20B is an explanatory diagram showing the air flow flowing into the air holes of the first embodiment. FIG. 21A is an explanatory diagram showing the velocity distribution of the air flowing into the air holes of the comparative example. FIG. 21B is an explanatory diagram showing the velocity distribution of the air flowing into the air holes of the first embodiment.

[0089] First, the mounting of the Peltier element unit 60, which is a comparative example shown in FIGS. 20A and 21A, will be described. The main body 62 side of the Peltier element unit 60 is inserted from the inner side 30a of the element mounting portion 30 formed in the element mounting portion 30 of the temperature control vest 1. The Peltier element unit 60 is disposed in the element insertion hole 32 with the inner flange 131 of the comparative example in contact with the outer peripheral edge portion 31 of the element of the element insertion hole 32. Subsequently, the Peltier element unit 60 of the comparative example includes a ring fastener 140 having an annular outer flange 141 projecting in an annular plate shape, and the outer flange 141 is brought into contact with the back fabric 3B from the outside of the back fabric 3B. The ring fastener 140 of the comparative example is placed in the internal space between the lining 11 and the back fabric 3B. The outer peripheral edge portion 31 of the element is sandwiched between the inner flange 131 of the cylindrical portion 130 of the comparative example and the outer flange 141 of the ring fastener 140 of the comparative example. By screwing and fixing the male screw 132 of the cylindrical portion 130 of the comparative example and the female screw 142 of the ring fastener 140 of the comparative example, the element mounting portion 30 is sandwiched between the inner flange 131 of the comparative example and the outer flange 141 of the comparative example. Thus, as shown in FIGS. 20A and 21A, the Peltier element unit 60 of the comparative example is mounted in a state fixed to the element mounting portion 30 and the back fabric 3B.

[0090] The inclination angles θ of the front surface 131a and the back surface 131b of the inner flange 131 of the Peltier element unit 60 in the comparative example are 0° with respect to the heat dissipation surface 61 (cooling surface 61A or heating surface 61B). That is, as shown in FIG. 20A, the inner flange 131 of the Peltier element unit 60 is parallel to the heat dissipation surface 61 (cooling surface 61A or heating surface 61B). Thereby, the inner flange 63 of the Peltier element unit 60 in the comparative example does not have a function of changing the flow of the air flowing into the air hole 64a of the Peltier element unit 60 downward.

[0091] As shown in FIG. 20A, when the inclination angle θ of the inner flange 131 of the comparative example is 0°, a part of the air AR (air AR1, air AR2, air AR3, air AR4) which is the air sent along with the rotation of the fan 42 by the blower unit 40 flows into the air hole 64a. The air AR (air AR1, air AR2, air AR3, air AR4) flows into the air hole 64a without colliding with the inner flange 63 and flows into the inside of the Peltier element unit 60. The air AR (air AR1, air AR2, air AR3, air AR4) that has flowed into the inside of the Peltier element unit 60 may or may not contact the plurality of cooling fins 65a and the heat exchange surface 65.

[0092] As shown in FIG. 20B, when the inclination angle θ of the inner flange 63 is 20°, a part of the air AR (air AR4, air AR5, air AR6, air AR7) which is the air sent along with the rotation of the fan 42 by the blower unit 40 flows toward the air hole 64a. Then, as shown in FIG. 20B, the air AR4 collides with the inner flange 63. As a result, the speed of the air AR4 increases and the pressure on the air AR4 decreases. As shown in FIG. 20B, the air AR4 flows along the inner flange 63 with an inclination angle θ of 20° toward the base of the cooling fin 65a of the heat exchange surface 65.

[0093] As shown in FIG. 20B, the air AR5 that has flowed toward the air hole 64a is compressed downward by the air AR4 that is flowing toward the air hole 64a along the inner flange 63 with an inclination angle θ of 20°. As a result, the flow of the air AR5 is changed to the base side of the cooling fin 65a.

[0094] As shown in FIG. 20B, the air AR4 that has passed through the air holes 64a flows into the inside of the Peltier element unit 60. As shown in FIG. 20B, the air AR6 that has passed through the air holes 64a and flows into the inside of the Peltier element unit 60 is compressed downward by the air AR4 that has flowed into the inside of the Peltier element unit 60. As a result, the flow of the air AR6 is changed to the base side of the cooling fins 65a. As shown in FIG. 20B, the air AR7 that has passed through the air holes 64a and flows into the inside of the Peltier element unit 60 flows directly toward the heat exchange surface 65.

[0095] As shown in FIG. 20B, the inner flange 63 of the first embodiment has a function of changing the flow directions of the air AR5 and the air AR6 toward the air holes 64a to the base of the cooling fins 65a by making the flow of the air AR4 that has collided with the inner flange 63 downward.

[0096] Next, with reference to FIG. 21A, a description will be given of changes in the velocity distribution of air when the inner flange 131 of the comparative example is parallel to the heat dissipation surface 61 (cooling surface 61A or heating surface 61B).

[0097] The first comparative velocity distribution HP1 shown in FIG. 21A is the velocity distribution of a part of the air sent along with the rotation of the fan 42 by the blower unit 40. As shown in FIG. 21A, the apex of the first comparative velocity distribution HP1 in the vicinity of the inner flange 131 of the comparative example faces the cooling fins 65a of the heat exchange surface 65. The first comparative velocity distribution HP1 moves toward the cooling fins 65a of the heat exchange surface 65.

[0098] When a part of the air sent along with the rotation of the fan 42 by the air supply unit 40 moves below the inner flange 63 of the Peltier element unit 60, the velocity distribution of a part of the air is the second comparative velocity distribution HP2 shown in FIG. 20A. As shown in FIG. 21A, the apex of the second comparative velocity distribution HP2 in the vicinity of the inner flange 131 of the Peltier element unit 60 of the comparative example faces the cooling fins 65a of the heat exchange surface 65, similar to the first comparative velocity distribution HP1. The second comparative velocity distribution HP2 moves toward the cooling fins 65a of the heat exchange surface 65.

[0099] When a part of the air sent along with the rotation of the fan 42 by the air supply unit 40 moves inside the Peltier element unit 60, the velocity distribution of a part of the air is the third comparative velocity distribution HP3 shown in FIG. 21A. As shown in FIG. 21A, the apex of the third comparative velocity distribution HP3 that has moved inside the Peltier element unit 60 of the comparative example faces the cooling fins 65a of the heat exchange surface 65. When the inner flange 63 of the comparative example is parallel to the heat dissipation surface 61 (cooling surface 61A or heating surface 61B), the flow of air toward the air holes 64a does not change due to the inner flange 131, and it will move toward the cooling fins 65a.

[0100] Next, with reference to FIG. 21B, the change in the air velocity distribution when the inner flange 63 of the first embodiment is inclined at an inclination angle of 20° with respect to the heat dissipation surface 61 (cooling surface 61A or heating surface 61B) will be described.

[0101] The first inclined velocity distribution ZP1 shown in FIG. 21B is the velocity distribution of a part of the air sent along with the rotation of the fan 42 by the air supply unit 40 in the vicinity of the inner flange 63 of the first embodiment. As shown in FIG. 21B, the apex of the first inclined velocity distribution ZP1 in the vicinity of the inner flange 63 of the first embodiment faces the cooling fins 65a of the heat exchange surface 65. The first inclined velocity distribution ZP1 moves toward the cooling fins 65a of the heat exchange surface 65.

[0102] Next, when a part of the air sent along with the rotation of the fan 42 by the blower unit 40 moves downward due to the inner flange 63 of the first embodiment, the velocity distribution of a part of the air is the second inclined velocity distribution ZP2 shown in FIG. 21B. A part of the air sent along with the rotation of the fan 42 by the blower unit 40 flows along the inner flange 63 with an inclination angle θ of 20° toward the base of the cooling fins 65a of the heat exchange surface 65 (see FIG. 20B). As a result, the apex of the second inclined velocity distribution ZP2 moves to the base side of the cooling fins 65a and faces the base of the cooling fins 65a of the heat exchange surface 65. The second inclined velocity distribution ZP2 moves toward the base of the cooling fins 65a of the heat exchange surface 65.

[0103] Next, when the air sent along with the rotation of the fan 42 by the blower unit 40 moves inside the Peltier element unit 60, the velocity distribution of the air is the third inclined velocity distribution ZP3 shown in FIG. 21B. The air accompanying the rotation of the fan 42 flows along the inner flange 63 with an inclination angle θ of 20° toward the base of the cooling fins 65a of the heat exchange surface 65 (see FIG. 20B). As a result, the apex of the third inclined velocity distribution ZP3 faces the base of the cooling fins 65a of the heat exchange surface 65, similar to the second inclined velocity distribution ZP2. Thereby, the air flowing into the air holes 64a of the first embodiment collides with the inner flange 63 of the first embodiment, increasing its velocity and decreasing its pressure, so that, as shown in FIG. 21B, the air flow changes to flow toward the base of the cooling fins 65a.

[0104] As the fan 42 rotates by the air supply unit 40, a part of the air sent is flowing along the inner flange 63 with an inclination angle θ of 20° toward the base of the cooling fins 65a of the heat exchange surface 65 (see FIGS. 20B and 21B). Thereby, the inner flange 63 of the first embodiment can change the flow of the air flowing in below the inner flange 63 to the base side of the cooling fins 65a. Therefore, when looking at the entire cooled air (for example, 35° C.) inside the temperature control vest 1 in a planar manner, it reaches the cooling fins 65a located directly below the air blower 100 where the air flowing in from the air holes 64a of the comparative example could not come into contact. Therefore, the cooling efficiency by the Peltier element unit 60 of the first embodiment can be increased by about 10% compared to the case where the inner flange 63 is parallel (see FIGS. 20A and 21A). By increasing the cooling efficiency of the Peltier element unit 60 by about 10%, the power consumption of the motor that rotates the exhaust fan 101 can be reduced by about 10%, and the effective cooling time of the temperature control vest 1 can be extended from, for example, 120 minutes to 132 minutes.

[0105] <Regarding the air flow inside the temperature control vest 1> Next, with reference to FIG. 22, the air flow inside the temperature control vest 1 will be described. FIG. 22 is an explanatory diagram for explaining the air flow sent from the air supply unit of the temperature control vest shown in FIG. 1.

[0106] As shown in FIG. 22, a part of the air AR sent with the rotation of the fan 42 by the air supply unit 40 is guided through the center back portion 13 toward the collar portion 9 and is discharged from the collar portion 9 to the outside of the temperature control vest 1. A part of the air AR sent with the rotation of the fan 42 by the air supply unit 40 is taken into the air holes 64a of the first Peltier element unit 60A through the center back portion 13. In this case, the cooling fins 65a are cooled by the air AR taken in from the air holes 64a, and the air that has undergone heat exchange from the discharge portion 62b is discharged.

[0107] As shown in FIG. 22, a part of the air AR fed in with the rotation of the fan 42 by the blower unit 40 is guided toward the first sleeve portion 10A and discharged from the first sleeve portion 10A to the outside of the temperature control vest 1. A part of the air AR fed in with the rotation of the fan 42 by the blower unit 40 is taken into the air holes 64a of the second Peltier element unit 60B. In this case, the cooling fins 65a are cooled by the air AR taken in from the air holes 64a, and the air that has undergone heat exchange is discharged from the discharge portion 62b.

[0108] As shown in FIG. 22, a part of the air AR fed in with the rotation of the fan 42 by the blower unit 40 is guided toward the second sleeve portion 10B and discharged from the second sleeve portion 10B to the outside of the temperature control vest 1. A part of the air AR fed in with the rotation of the fan 42 by the blower unit 40 is taken into the air holes 64a of the third Peltier element unit 60C. In this case, the cooling fins 65a are cooled by the air AR taken in from the air holes 64a, and the air that has undergone heat exchange is discharged from the discharge portion 62b.

[0109] <Regarding the blower operation unit> FIG. 23 is a block diagram showing the configuration of the blower operation unit provided in the temperature control vest according to the first embodiment. As shown in FIG. 23, the blower operation unit 80 includes a blower control unit 81, a blower operation unit 82, a blower display unit 83, and the like. In the blower operation unit 80, the blower operation unit 82 and the blower display unit 83 are electrically connected to the blower control unit 81.

[0110] The blower operation unit 82 is configured in such a manner that by gently pressing with a finger the pressing portion on the upper surface of the blower operation unit 80 based on a predetermined operation mode, an operation for controlling the on / off switching of the energization to the motor of the drive unit 33 is enabled. The blower display unit 83 is a display unit on the upper surface of the blower operation unit 80 and is configured in such a manner that it can emit white light.

[0111] <Regarding the temperature control operation unit> FIG. 24 is a block diagram showing the configuration of a temperature control operation unit provided in the temperature control vest according to the embodiment. As shown in FIG. 24, the temperature control operation unit 90 includes a temperature control unit 91, a temperature control operation unit 92, a temperature control display unit 93, and the like. In the temperature control operation unit 90, the temperature control operation unit 92 and the temperature control display unit 93 are electrically connected to the temperature control unit 91.

[0112] The temperature control operation unit 92 is configured in such a manner that, by pressing a pressing portion on the upper surface of the temperature control operation unit 90, operations for controlling the switching of the energization on / off of the Peltier element PE with respect to the first to third Peltier element units 60A, 60B, and 60C are enabled. Further, the temperature control operation unit 92 is configured in such a manner that, by pressing a pressing portion on the upper surface of the temperature control operation unit 90, operations for controlling the switching of the energization on / off of a motor (not shown) that rotates the exhaust fan 101 are enabled. The temperature control display unit 93 is a display unit on the upper surface of the temperature control operation unit 90 and is configured in such a manner that it can selectively emit light in a plurality of colors.

[0113] When the temperature control unit 91 has control to reverse the direction of the direct current supplied from the portable battery 84 to the Peltier element PE, the temperature control operation unit 92 gently presses based on a predetermined operation mode different from the on / off switching operation of the energization through the pressing portion on the upper surface of the temperature control operation unit 90. Thereby, it is possible to switch the polarity of the current flowing through the first to third Peltier element units 60A, 60B, and 60C.

[0114] In the Peltier element unit 60, in the Peltier element PE, when the direction of the supplied direct current becomes reverse, the functions of one surface and the other surface are mutually inverted. Therefore, when the temperature control unit 91 is configured to be able to reverse the polarity of the current supplied to the Peltier element PE, the heat dissipation surface 61 can selectively vary between the cooling surface 61A cooled by heat absorption and the heating surface 61B heated by heat generation by the temperature control unit 91. Thereby, on the heat dissipation surface 61, the cooling surface 61A and the heating surface 61B are mutually interchanged. When the temperature control unit 91 does not have a function of switching the direction of the current with respect to the Peltier element PE, the heat dissipation surface 61 is either one of the cooling surface 61A or the heating surface 61B. The Peltier element unit 60 is configured to be able to transfer heat to the body either the cold heat presented on the cooling surface 61A under heat absorption or the warm heat presented on the heating surface 61B that generates heat simultaneously with heat absorption on the opposite side of the cooling surface by the energized Peltier element PE.

[0115] <Second Embodiment> Hereinafter, the characteristic points of the temperature control vest 1 of the second embodiment will be described in detail. Unless otherwise stated, the temperature control vest 1 of the first embodiment is also applied to the second embodiment. Of course, the configurations according to the second embodiment may be appropriately combined. The technical features in the first embodiment and the second embodiment below can be appropriately deleted if they are not described as essential in this specification. In the second embodiment, the case where the temperature adjustment unit is a fan and the case where the body temperature adjustment device is a blowing unit will be described.

[0116] In the first embodiment, the blower unit 40 is attached to the temperature control vest 1 in a state where the male screw 48 of the main body 41 and the female screw 112 of the pressing member 110 are screwed together, and the flange 47 and the pressing portion 111 sandwich the outer peripheral edge portion 21 of the fan and the back fabric 3B. In the first embodiment, the Peltier element unit 60 is attached to the temperature control vest 1 in a state where the inner flange 63 and the outer flange 121 sandwich the element mounting portion 30 and the back fabric 3B by being fixed by the engagement of the regulating portion 67 of the guide rail 66 and the protrusion 122 of the ring fastener 120. However, it is not limited to this. In the second embodiment, the Peltier element unit 60 is configured to be attached to the temperature control vest 1 in a state where the inner flange 63 and the outer flange 121 sandwich the element mounting portion 30 and the back fabric 3B by screwing and fixing the male screw of the main body 62 and the female screw of the ring fastener 120. The blower unit 40 of the second embodiment is configured to be attached to the temperature control vest 1 in a state where the flange 47 and the pressing member 110 sandwich the fan mounting portion 20 and the back fabric 3B by being fixed by the engagement of the regulating portion 54 of the guide rail 50 (to be described later) and the protrusion of the pressing member 110.

[0117] <Regarding the blower unit 40 of the second embodiment> The blower unit 40 of the second embodiment will be described with reference to FIGS. 25 to 26. FIG. 25 is an explanatory view showing a state in which the blower unit according to the second embodiment is disassembled into a main body portion and a pressing member. FIG. 26 is a developed view of the inner case peripheral wall portion according to the second embodiment developed on a plane.

[0118] As shown in FIG. 25, in the casing 44 according to the second embodiment, a guide rail 50 is provided on the outer peripheral surface of the inner case peripheral wall portion 49. The guide rails 50 adjacent to each other in the circumferential direction CR are arranged at the same height in the axial direction L. As shown in FIG. 26, the guide rail 50 extends in an arc shape along the circumferential direction CR of the main body portion 41 between one end 50a and the other end 50b while facing the inner case portion 45 having the discharge port 45a. A plurality (for example, 4) of guide rails 50 are provided at different positions in the circumferential direction of the inner case peripheral wall portion 49. As shown in FIG. 25, mounting groove portions 52 are respectively provided between the plurality of guide rails 50 and the flange 47. The plurality (for example, 4) of mounting groove portions 52 are provided along the circumferential direction CR of the inner case peripheral wall portion 49 (see FIG. 27). The four guide rails 50 are respectively provided with gaps 51 between the adjacent guide rails 50 intermittently (see FIG. 27). A plurality (for example, 4) of gaps 51 are provided on the outer peripheral surface of the main body portion 41.

[0119] Each of the plurality of guide rails 50 has a sliding surface 53 between one end 50a and the other end 50b of each guide rail 50. As shown in FIG. 26, a plurality (for example, 4) of restricting portions 54 are arranged on each of the sliding surfaces 53 of the plurality of guide rails 50. Each of the plurality of restricting portions 54 restricts the movement operation of each of the plurality of protrusions 113 that move along the sliding surface 53 toward the anti-circumferential direction ACR of the main body portion 41. The restricting portions 54 are intermittently arranged in the order of the first restricting portion 54a ⇒ the second restricting portion 54b ⇒ the third restricting portion 54c ⇒ the fourth restricting portion 54d on the sliding surface 53 connecting one end 50a and the other end 50b of each guide rail 50. Each of the plurality of fourth restricting portions 54d is configured to have a height that the plurality of protrusions 113 cannot overcome.

[0120] On the inner peripheral surface 110a of the pressing member 110 according to the second embodiment, protrusions 113 that can be connected to each of the plurality of guide rails 50 are provided. The protrusions 113 are provided in a plurality (for example, four) at intervals in the circumferential direction CR of the pressing member 110. The plurality of protrusions 113 can engage with the restricting portions 54 of the respective guide rails 50. The protrusions 113 adjacent to each other in the circumferential direction CR are arranged at the same height in the axial direction L. Each of the plurality of protrusions 113 is formed so as to be able to pass through each of the plurality of gaps 51. One protrusion 113 engages with one guide rail 50 through the gap 51. The plurality of protrusions 113 are inclined toward the side opposite to the pressing portion 111 in the radial direction RD with respect to the axial center line AX of the pressing member 110, and the inclination angle θ is 3°. Thereby, each of the plurality of protrusions 113 is easily connected to each of the plurality of guide rails 50.

[0121] Next, with reference to FIG. 26, the sliding surfaces 53 of the plurality of guide rails 50 provided on the inner case peripheral wall portion 49 developed on a plane will be described. As shown in FIG. 26, each of the plurality of guide rails 50 is inclined toward the outer case portion 46 having the air holes 46a with respect to a plane parallel to the axial direction L along the axial center line AX of the main body portion 41. All of the plurality of guide rails 50 in the second embodiment are given an inclination angle θ of 3° as an example between one end 50a and the other end 50b. Thereby, all of the plurality of guide rails 50 in the second embodiment are formed in an inclined manner with a height difference ΔH in the axial direction L between one end 50a and the other end 50b. That is, the inclination angle θ of the sliding surface 53 according to the second embodiment is 3° toward the outer case portion 46 having the air holes 46a with respect to a plane parallel to the axial direction L along the axial center line AX of the main body portion 41.

[0122] <Mounting of the blower unit 40 of the second embodiment> Next, with reference to FIGS. 27 to 28, the mounting of the blower unit 40 according to the second embodiment on the temperature control vest 1 will be described. FIG. 27 is an explanatory view showing a method of mounting the blower unit according to the second embodiment on the temperature control vest. FIG. 28 is a partial cross-sectional view of the blower unit mounted on the temperature control vest.

[0123] In the installation of the blower unit 40 according to the second embodiment, as shown in FIG. 27, first, the inner case portion 45 of the main body portion 41 is inserted from the outside 20a of the fan mounting portion 20 into the fan insertion hole 22 formed in the fan mounting portion 20 and the insertion hole 3b of the back fabric 3B. With the flange 47 abutted against the outer peripheral edge portion 21 of the fan, the outer case portion 46 is disposed in the fan insertion hole 22 and the insertion hole 3b of the back fabric 3B.

[0124] Subsequently, a person disposes the pressing member 110 near the outer peripheral edge portion 21 of the fan from the side of the lining 11 of the temperature control vest 1. Then, the person causes the inner case portion 45 to enter inside the pressing member 110. When the inner case peripheral wall portion 49 enters up to the inside of the pressing member 110, each of the plurality of protrusions 113 enters each of the plurality of gaps 51. As a result, the back fabric 3B and the outer peripheral edge portion 21 of the fan are sandwiched between the flange 47 and the pressing portion 111. Subsequently, the person relatively rotates the pressing member 110 in the circumferential direction CR of the main body portion 41, so that each of the plurality of protrusions 113 of the pressing member 110 slides along the circumferential direction CR of the main body portion 41 while contacting the sliding surface 53 of each of the respective guide rails 50. Subsequently, the person relatively rotates the main body portion 41 and the pressing member 110 in the circumferential direction CR of the main body portion 41, and causes each of the plurality of protrusions 113 to overcome each of the plurality of restricting portions 54 disposed on the sliding surface 53. By each of the plurality of restricting portions 54 that the plurality of protrusions 113 have overcome, each of the plurality of protrusions 113 is restricted from moving in the anti-circumferential direction ACR of the main body portion 41 (see FIG. 26). After each of the plurality of protrusions 113 has overcome each of the plurality of restricting portions 54 and the movement has stopped, each of the plurality of protrusions 113 that have stopped moving comes into surface contact with and engages with each of the plurality of restricting portions 54, thereby fixing them. Therefore, the back fabric 3B and the outer peripheral edge portion 21 of the fan are fixed in a state of being sandwiched between the flange 47 and the pressing member 110. The plurality of protrusions 113 and the restricting portions 54 according to the second embodiment can be connected, but do not provide mutually opposite spiral screws or the like. Therefore, the protrusions 113 of the pressing member 110 and the restricting portions 54 of the guide rail 50 are fixed by engagement, not by screwing.

[0125] <Regarding the thickness of the fabric sandwiched between the flange 47 and the pressing member 110> Using FIGS. 29 to 31, the location where the protrusion 113 and the sliding surface 53 are engaged and fixed by surface contact according to the thickness of the fabric sandwiched between the flange 47 and the pressing portion 111 will be described. FIG. 29 is a side view of the air blowing unit according to the second embodiment, and is an explanatory view showing a case where the flange and the pressing portion are engaged at the first stage. FIG. 30 is a side view of the air blowing unit according to the second embodiment, and is an explanatory view showing a case where the flange and the pressing portion are engaged at the second stage. FIG. 31 is a side view of the air blowing unit according to the second embodiment, and is an explanatory view showing a case where the flange and the pressing portion are engaged at the third stage.

[0126] Using FIG. 29, a case will be described where each of the plurality of protrusions 113 overrides the first regulating portion 54a of each guide rail 50 and the guide rail 50 engages with the protrusion 113 in the first stage. When the thickness of the fabric made of the temperature control vest 1 is X4 (for example, about 3 mm), with the fabric sandwiched between the flange 47 and the pressing portion 111, a person enters the main body portion 41 inside the pressing member 110. As a result, each of the protrusions 113 enters each of the gaps 51. Subsequently, when the person relatively rotates the main body portion 41 and the pressing member 110 in the circumferential direction CR of the main body portion 41, each of the plurality of protrusions 113 enters the attachment groove portion 52 from one end 50a of the guide rail 50. Subsequently, when the person relatively rotates the main body portion 41 and the pressing member 110 in the circumferential direction CR of the main body portion 41, each of the plurality of protrusions 113 slides on the sliding surface 53 of each guide rail 50 along the circumferential direction CR of the main body portion 41. When the person relatively rotates the main body portion 41 and the pressing member 110 by, for example, 15 degrees along the circumferential direction CR of the main body portion 41, each of the plurality of protrusions 113 overrides each of the plurality of first regulating portions 54a disposed on the sliding surface 53. The movement of each protrusion 113 in the anti-circumferential direction ACR is regulated by each of the overridden first regulating portions 67a. The angle by which the main body portion 41 and the pressing member 110 relatively rotate along the circumferential direction CR of the main body portion 41 for each of the plurality of protrusions 113 to override each of the plurality of first regulating portions 54a is not limited to 15 degrees. For example, it is preferably either 15 degrees or 20 degrees.

[0127] As shown in Fig. 29, a plurality of protrusions 113 that have stopped moving in the circumferential direction CR of the main body 41 at the first stage are fixed by coming into surface contact and engaging with respective ones of a plurality of first restricting portions 54a on the sliding surface 53. In this case, with the fabric having a thickness of X4 (for example, about 3 mm) of the temperature control vest 1 sandwiched between the flange 47 and the pressing member 110, the blower unit 40 can be attached to the temperature control vest 1. When detaching the blower unit 40 from the temperature control vest 1, a person relatively rotates the main body 41 and the pressing member 110 in the anti-circumferential direction ACR of the main body 41, for example, by 15 degrees, so that each of the plurality of protrusions 113 gets over each of the first restricting portions 54a. Thereby, the blower unit 40 can be detached from the temperature control vest 1.

[0128] Next, with reference to Fig. 30, the case where each of the plurality of protrusions 113 gets over the first restricting portion 54a of each of the respective guide rails 50 and the guide rail 50 and the protrusion 113 engage with each other at the second stage will be described. When the thickness of the fabric of the temperature control vest 1 is X5 (for example, about 2 mm), with the fabric sandwiched between the flange 47 and the pressing portion 111, a person causes the main body 41 to enter inside the pressing member 110. Thereby, each of the protrusions 113 enters each of the gaps 51. Subsequently, when the person relatively rotates the main body 41 and the pressing member 110 in the circumferential direction CR of the main body 41, each of the plurality of protrusions 113 enters the attachment groove portion 52 from one end 50a of the guide rail 50. Subsequently, when the person relatively rotates the main body 41 and the pressing member 110 in the circumferential direction CR of the main body 41, each of the plurality of protrusions 113 slides on the sliding surface 53 of each of the respective guide rails 50 along the circumferential direction CR of the main body 41. When the person relatively rotates the main body 41 and the pressing member 110 in the circumferential direction CR of the main body 41, for example, by 15 degrees, each of the plurality of protrusions 113 gets over each of the plurality of first restricting portions 54a disposed on the sliding surface 53. The movement of each of the protrusions 113 in the anti-circumferential direction ACR is restricted by each of the first restricting portions 67a that has been got over.

[0129] Furthermore, when a person relatively rotates the main body part 41 and the pressing member 110 along the circumferential direction CR of the main body part 41 by, for example, 15 degrees, each of the plurality of protrusions 113 slides on the sliding surface 53 and gets over each of the plurality of second restricting parts 54b. The movement of each of the protrusions 113 in the anti-circumferential direction ACR is restricted by each of the second restricting parts 54b that has been got over. The angle by which the main body part 41 and the pressing member 110 relatively rotate along the circumferential direction CR of the main body part 41 in order for each of the plurality of protrusions 113 to get over each of the plurality of second restricting parts 54b is not limited to 15 degrees. For example, it is preferably either 15 degrees or 20 degrees.

[0130] As shown in FIG. 30, the plurality of protrusions 113 that stopped moving in the circumferential direction CR of the main body part 41 at the second stage are fixed by coming into surface contact and engaging with each of the plurality of second restricting parts 54b on the sliding surface 53. In this case, with the fabric having a thickness of X5 (for example, about 2 mm) of the fabric forming the temperature control vest 1 sandwiched between the flange 47 and the pressing member 110, the blower unit 40 can be attached to the temperature control vest 1. When releasing the attachment of the blower unit 40, by relatively rotating the main body part 41 and the pressing member 110 in the anti-circumferential direction ACR of the main body part 41 by, for example, 30 degrees, each of the plurality of protrusions 113 gets over each of the first restricting part 54a and the second restricting part 54b. Thereby, the blower unit 40 can be detached from the temperature control vest 1.

[0131] Next, with reference to FIG. 31, the case where each of the plurality of protrusions 113 overrides the first restricting portion 54a of each guide rail 50 and the guide rail 50 engages with the protrusion 113 at the third stage will be described. When the thickness of the fabric forming the temperature control vest 1 is X6 (for example, about 1 mm), with the fabric sandwiched between the flange 47 and the pressing portion 111, a person enters the main body portion 41 inside the pressing member 110. As a result, each of the protrusions 113 enters each of the gaps 51. Subsequently, when the person relatively rotates the main body portion 41 and the pressing member 110 in the circumferential direction CR of the main body portion 41, each of the plurality of protrusions 113 enters the attachment groove portion 52 from one end 50a of the guide rail 50. Subsequently, when the person relatively rotates the main body portion 41 and the pressing member 110 in the circumferential direction CR of the main body portion 41, each of the plurality of protrusions 113 slides on the sliding surface 53 of each guide rail 50 along the circumferential direction CR of the main body portion 41. When the person relatively rotates the main body portion 41 and the pressing member 110 by, for example, 15 degrees along the circumferential direction CR of the main body portion 41, each of the plurality of protrusions 113 overrides each of the plurality of first restricting portions 54a disposed on the sliding surface 53. The movement of each protrusion 113 in the anti-circumferential direction ACR is restricted by each of the overridden first restricting portions 67a.

[0132] Furthermore, when the person relatively rotates the main body portion 41 and the pressing member 110 by, for example, 15 degrees along the circumferential direction CR of the main body portion 41, each of the plurality of protrusions 113 slides on the sliding surface 53 and overrides each of the plurality of second restricting portions 54b. The movement of each protrusion 113 in the anti-circumferential direction ACR is restricted by each of the overridden second restricting portions 54b.

[0133] Furthermore, when a person rotates the main body part 41 and the pressing member 110 relative to each other by, for example, 15 degrees along the circumferential direction CR of the main body part 41, each of the plurality of protrusions 113 slides on the sliding surface 53 and crosses each of the plurality of third restricting parts 54c. By each of the crossed third restricting parts 54c, the movement of each of the protrusions 113 in the anti-circumferential direction ACR is restricted. The angle by which the main body part 41 and the pressing member 110 are relatively rotated along the circumferential direction CR of the main body part 41 in order for each of the plurality of protrusions 113 to cross each of the plurality of third restricting parts 54c is not limited to 15 degrees. For example, it is preferably either 15 degrees or 20 degrees.

[0134] As shown in FIG. 31, the plurality of protrusions 113 that have stopped moving in the circumferential direction CR of the main body part 41 at the third stage are fixed by being in surface contact with and engaging with each of the plurality of third restricting parts 54c on the sliding surface 53. In this case, the blower unit 40 can be attached to the temperature control vest 1 in a state where a fabric having a thickness of X6 (for example, about 1 mm) of the fabric constituting the temperature control vest 1 is sandwiched between the flange 47 and the pressing member 110. When releasing the attachment of the blower unit 40, by a person relatively rotating the main body part 41 and the pressing member 110 by, for example, 45 degrees in the anti-circumferential direction ACR of the main body part 41, each of the plurality of protrusions 113 crosses each of the first restricting part 54a to the third restricting part 54c. Thereby, the blower unit 40 can be detached from the temperature control vest 1.

[0135] When each of the plurality of protrusions 113 crosses the third restricting part 54c, even if a person relatively rotates the main body part 41 and the pressing member 110 in the circumferential direction CR of the main body part 41, each of the plurality of protrusions 113 cannot cross each of the plurality of fourth restricting parts 54d. Thereby, it is possible to prevent the blower unit 40 from falling off the temperature control vest 1 due to the relative rotation of the main body part 41 and the pressing member 110 in the circumferential direction of the main body part 41.

[0136] When the blower unit 40 according to the second embodiment is attached to the vest body 2, first, each of the plurality (for example, 4) of protrusions 113 that make up the plurality of protrusions enters the plurality (for example, 4) of gaps 51 in the axial direction L along the axial center line AX of the main body portion 41. As a result, the flange 47 and the pressing member 110 sandwich the fabric of the temperature control vest 1. Subsequently, the main body portion 41 and the pressing member 110 are relatively rotated, and in a state where the flange 47 and the pressing portion 111 sandwich the fabric of the temperature control vest 1, each of the plurality of protrusions 113 has its movement restricted by the regulation portion 54 that has been overcome. Further, by each of the plurality of protrusions 113 engaging with each of the regulation portions 54, the blower unit 40 is attached to the temperature control vest 1. Therefore, a person can attach the blower unit 40 to the temperature control vest 1 with a one-touch operation. Further, as the main body portion 41 and the pressing member 110 are relatively rotated, the engagement positions with each of the plurality of protrusions 113 can be changed step by step. As a result, if the thickness of the fabric of the temperature control vest 1 is about 3 mm, the plurality of protrusions 113 engage with the first regulation portion 54a, and the blower unit 40 can be attached to the temperature control vest 1. If the thickness of the fabric of the temperature control vest 1 is about 2 mm, the plurality of protrusions 113 engage with the second regulation portion 54b, and the blower unit 40 can be attached to the temperature control vest 1. If the thickness of the fabric of the temperature control vest 1 is about 1 mm, the plurality of protrusions 113 engage with the third regulation portion 54c, and the blower unit 40 can be attached to the temperature control vest 1. Therefore, regardless of the thickness of the fabric of the temperature control vest 1, a person can attach the blower unit 40 to the temperature control vest 1 corresponding to that thickness. Therefore, it becomes easy to attach the blower unit 40 according to the second embodiment to the fabric of the temperature control vest 1, and the usability of the temperature control vest 1 can be improved. Further, even if the back fabric 3B and the fan mounting portion 20 are sandwiched many times by the flange 47 and the pressing portion 111, it is possible to make it difficult for the back fabric 3B and the fan mounting portion 20 to plastically deform. Therefore, it is possible to prevent rattling when the blower unit 40 is attached to the temperature control vest 1 and damage to the back fabric 3B and the fan mounting portion 20.

[0137] Next, the operation and effects of the temperature control vest 1 according to the first embodiment and the second embodiment will be described.

[0138] In a temperature control vest 1 made of a fabric (fan outer peripheral edge 21, element outer peripheral edge 31) forming the temperature control unit (Peltier element PE, fan 42) according to the first and second embodiments, a body temperature control device (air blowing unit 40, Peltier element unit 60) capable of adjusting the temperature of the body of the wearer HM is detachably attachable to insertion holes (fan insertion hole 22, element insertion hole 32) formed in the fabric. In the body temperature control device, a main body part (main body part 41, main body part 62) having an intake part (inner case part 45, air cylinder part 64) in which air holes (air hole 46a, air hole 64a) for taking in air are formed, a flange (flange 47, inner flange 63) protruding outward on the outer peripheral surface of the main body part, a plurality of guide rails (guide rail 50, guide rail 66) extending in an arc shape along the outer peripheral surface of the main body part between one end (one end 50a, one end 66a) and the other end (the other end 50b, the other end 66b), and an annular fixing member (pressing member 110, ring fastener 120) having a plurality of protrusions (protrusion 113, protrusion 122) connectable to the guide rails (guide rail 50, guide rail 66). Each of the plurality of guide rails is intermittently provided with a plurality of restricting parts (restricting part 54 (first restricting part 54a, second restricting part 54b, third restricting part 54c, fourth restricting part 54d), restricting part 67 (first restricting part 67a, second restricting part 67b, third restricting part 67c, fourth restricting part 67d)) for restricting the movement operation of the protrusions on a sliding surface (sliding surface 53, sliding surface 68) connecting the one end and the other end. The plurality of restricting parts include a first restricting part (first restricting part 54a, first restricting part 67a) and a second restricting part (second restricting part 54b, second restricting part 67b) provided on the other end side of the first restricting part. A plurality of gaps (gap 51, gap 70) extending in the axial direction L along the axial center line AX of the main body part are provided between the plurality of guide rails. The attachment of the body temperature control device to the fabric is performed by causing each protrusion constituting the plurality of protrusions to enter the gaps constituting the plurality of gaps in the axial direction L along the axial center line AX of the main body part, relatively rotating the flange and the fixing member, and engaging each protrusion constituting the plurality of protrusions with the first restricting part or the second restricting part in a state where the fabric is sandwiched between the flange and the fixing member.

[0139] According to this aspect, when the body temperature adjustment device (the blower unit 40, the Peltier element unit 60) is attached, each of the plurality of protrusions (the protrusion 113, the protrusion 122) enters in the axial direction L of the main body part (the main body part 41, the main body part 62) with respect to the plurality of gaps (the gap 51, the gap 70). Thereby, the flange (the flange 47, the inner flange 63) and the fixing member (the pressing member 110, the ring fastener 120) sandwich the fabric of the temperature control vest 1. Subsequently, when the main body part and the fixing member are relatively rotated and each of the plurality of protrusions gets over the first restricting part (the first restricting part 54a, the first restricting part 67a) or the second restricting part (the second restricting part 54b, the second restricting part 67b), the moving operation is restricted and engaged. Therefore, a person can attach the body temperature adjustment device to the fabric (the fan mounting part 20, the element mounting part 30) forming the temperature control vest 1 with a one-touch operation with a sense of moderation. Further, since poor tightening or loosening of the fixing member does not occur, it is possible to avoid the body temperature adjustment device falling off from the temperature control vest 1 or only the fixing member being lost. Therefore, it is possible to provide a clothing attachment structure of a body temperature adjustment device that simplifies the attachment of the body temperature adjustment device to the fabric forming the temperature control vest 1 and improves the usability of the temperature control vest 1, and a temperature control vest 1 configured with such a structure.

[0140] Also, in the clothing attachment structure of the body temperature adjustment device according to the first embodiment and the second embodiment, each of the plurality of guide rails (the guide rail 50, the guide rail 66) is formed in an inclined manner with a height difference ΔH by giving an inclination angle θ of 3° as an example in the axial direction L along the axial center line AX of the main body part (the main body part 41, the main body part 62) between one end (one end 50a, one end 66a) and the other end (the other end 50b, the other end 66b).

[0141] According to this aspect, when the thickness of the fabric is about 3 mm, each of the plurality of protrusions engages with the first restricting portion (first restricting portion 54a, first restricting portion 67a) with the fabric sandwiched between the flange (flange 47, inner flange 63) and the fixing member (pressing member 110, ring fastener 120). On the other hand, when the thickness of the fabric forming the clothing is about 2 mm, each of the protrusions constituting the plurality of protrusions is engaged with the second restricting portion (second restricting portion 54b, second restricting portion 67b) with the fabric sandwiched between the flange and the fixing member. Thereby, the body temperature adjusting device can be worn in a state where the fabric is firmly sandwiched between the flange and the fixing member so as not to fall off from the temperature control vest 1 regardless of the thickness of the fabric forming any clothing. Further, even when each of the plurality of protrusions engages with the first restricting portion or the second restricting portion with the fabric sandwiched between the flange and the fixing member, the fabric around the insertion holes (fan insertion hole 22, element insertion hole 32) is hardly plastically deformed. Thereby, it is possible to prevent the body temperature adjusting device from rattling and the fabric around the insertion holes from being damaged.

[0142] Further, in the clothing attachment structure of the body temperature adjusting device according to the first embodiment and the second embodiment, the inclination angle θ of the sliding surface (sliding surface 53, sliding surface 68) has an inclination angle θ of 3° as an example on the side of the taking-in portion (outer case portion 46, air cylinder portion 64) with respect to a plane parallel to the axial direction L along the axial center line AX of the main body portion (main body portion 41, main body portion 62).

[0143] According to this aspect, due to the relative rotation of the main body portion (main body portion 41, main body portion 62) and the fixing member (pressing member 110, ring fastener 120), each of the plurality of protrusions (protrusion 113, protrusion 122) slides on the sliding surface (sliding surface 53, sliding surface 68) having an inclination angle of 3°. Thereby, it is possible to prevent the air intake from the air holes (air holes 46a, air holes 64a) from being obstructed by the sandwiched fabric and the fabric around the insertion holes (fan insertion hole 22, element insertion hole 32) from being damaged by sliding on the sliding surface of each of the plurality of protrusions.

[0144] In the clothing attachment structure of the body temperature adjustment device according to the first embodiment, the temperature adjustment unit is a Peltier element PE, and the body temperature adjustment device has a cooling surface 61A and a heat exchange surface 65 on the opposite side of the cooling surface 61A, and is configured to be able to transfer the cold heat presented on the cooling surface 61A under heat absorption to the body by the Peltier element PE under energization.

[0145] According to this aspect, when the temperature control vest 1 is worn, the cooling surface 61A under heat absorption by the Peltier element PE under energization is brought into direct or indirect contact with the body surface BS of the wearer HM through a singlet or the like. Thereby, for example, it is possible to locally specialize only specific parts of the body surface desired by the wearer, such as parts that particularly feel hot or parts that are stuffy in a spot, and efficiently cool them.

[0146] In the clothing attachment structure of the body temperature adjustment device according to the first embodiment, a discharge portion 62b for discharging the air taken in from the air holes 64a is provided, the heat exchange surface 65 has a plurality of cooling fins 65a, the air cylinder portion 64 has air holes 64a formed in the circumference, the cooling surface 61A and the air cylinder portion 64 are attached to the body side of the temperature control vest 1, and the inner flange 63 has an inclined surface of 15 degrees or more and 30 degrees or less on the discharge portion 62b side with respect to the surface parallel to the cooling surface 61A.

[0147] According to this aspect, a plurality of cooling fins 65a of the heat exchange surface 65 of the Peltier element unit 60 are cooled by the air taken in from the air holes 64a of the air cylinder part 64. With respect to the plane parallel to the cooling surface 61A, the inner flange 63 having a surface 63a of 15 degrees or more and 30 degrees or less on the discharge part 62b side guides the air taken in from the air holes 64a to the base of the plurality of cooling fins 65a. That is, the area for heat exchange can be significantly increased by the cooling fins 65a. Further, by having the surface 63a of 15 degrees or more and 30 degrees or less on the inner flange 63, a part of the air flowing into the air holes 64a for cooling hits the inner flange 63 and becomes a downward flow. As a result, the flow of the air flowing in below the inner flange 63 is changed to the base side of the cooling fins 65a. Therefore, when the entire cooling air reaches the central part of the cooling fins when viewed in plan, the cooling efficiency can be increased by about 10% compared to the case where the flange is parallel. By increasing the cooling efficiency by about 10%, for example, in a configuration where the motor is driven from the discharge part 62b to rotate the exhaust fan 101 to discharge the air, the power consumption of the motor can be reduced by about 10%. Further, the effective cooling time of the temperature control device can be extended, for example, from 120 minutes to 132 minutes. Therefore, while suppressing the power consumption of the Peltier element unit 60, the cooling efficiency of the Peltier element unit 60 can be increased, and the risk of heat stroke for workers working outdoors in sweltering heat can be avoided.

[0148] In the clothing attachment structure of the body temperature adjustment device according to the second embodiment, the temperature adjustment unit is the fan 42, and the air blowing unit 40 is configured to be able to blow either cold air in a temperature state lower than the outside air or warm air in a temperature state higher than the outside air to the body of the wearer HM by the rotation of the fan 42.

[0149] According to this aspect, for example, it is possible to prevent the onset of heat stroke by supplying cold air (wind) to workers working outdoors in sweltering heat, workers working in a stuffy indoor environment, or people engaged in recreation, sports, watching games, etc. under the scorching sun. Conversely, for example, when used together with a heat source such as a hand warmer or a simple heater, the outside air supplied to the blower unit 40 can be blown toward the heat source, and warm air (wind) in a state heated by the heat source can be blown onto the body to warm the chilled body.

[0150] A temperature control vest 1 that is detachably attached with a body temperature adjustment device having a clothing attachment structure of the body temperature adjustment device according to the first embodiment to the second embodiment.

[0151] According to this aspect, it can be easily attached by inserting it into the insertion holes (fan insertion hole 22 and element insertion hole 32) of the fabric of the temperature control vest 1 that adopts the clothing attachment structure of the body temperature adjustment device (blower unit 40, Peltier element unit 60) according to the first embodiment to the second embodiment. Furthermore, a user-friendly temperature control vest 1 that can accommodate body temperature adjustment devices for any fabric thickness can be provided to the wearer.

[0152] <Third Embodiment> Hereinafter, the features of the temperature control vest 1 of the third embodiment will be described in detail. Unless otherwise specified, the temperature control vest 1 of the first embodiment is also applicable to the third embodiment. Of course, the components according to the third embodiment may be appropriately combined. The technical features in the first embodiment, the second embodiment, and the following third embodiment can be appropriately deleted if they are not described as essential in this specification.

[0153] In the first embodiment, all the Peltier element units 60 were of the same size. However, it is not limited to this. In the third embodiment, instead of the first Peltier element unit 60A, a fourth Peltier element unit 60D larger than the first Peltier element unit 60A can be attached to the temperature control vest 1. The fourth Peltier element unit 60D according to the third embodiment does not have a flange corresponding to the inner flange 63 described in the first embodiment. As a result, the fourth Peltier element unit 60D is configured to be attached to the temperature control vest 1 in a state where the element mounting portion 30 and the back fabric 3B are sandwiched between the sandwiching surface 154 of the ring fastener 150 and the stepped surface 76 of the fourth Peltier element unit 60D.

[0154] <Regarding the temperature control vest 1> FIG. 32 is a front view of the outer surface of the temperature control vest according to the third embodiment as viewed from the front body side, and a rear view of the same as viewed from the back body side is shown in FIG. 33. As shown in FIGS. 32 to 33, the temperature control vest 1 includes a vest body 2, a blower unit 40, a Peltier element unit 60, a blower operation unit 80, a temperature control operation unit 90, a portable battery 84, and the like. In the Peltier element unit 60 of the third embodiment, as shown in FIGS. 32 and 33, the Peltier element PE is electrically connected to the portable battery 84 through the temperature control wiring 95 via the temperature control operation unit 90.

[0155] <Regarding the vest body 2> The vest body 2 according to the third embodiment will be described with reference to FIGS. 32 to 33. Element mounting portions 30 on which the Peltier element units 60 can be mounted are provided at a plurality of positions on the lining 11, and in this embodiment, they are provided at three positions on the back body 5. As shown in FIG. 33, in the back body 5, the element mounting portions 30 are arranged at one position on the scapular portion 15, one position near the first sleeve hole portion 10A, and one position near the second sleeve hole portion 10B.

[0156] <Regarding the Peltier element unit 60 of the third embodiment> Next, the Peltier element unit 60 will be described with reference to FIGS. 34 to 37. FIG. 34 is a perspective view showing the heat dissipation surface side of the Peltier element unit according to the third embodiment. FIG. 35 is a perspective view showing the end face side of the small-diameter portion of the Peltier element unit according to the third embodiment. FIG. 36 is an exploded perspective view showing the configuration of the Peltier element unit according to the third embodiment. FIG. 37 is a development view in which the outer peripheral surface of the small-diameter portion according to the third embodiment is developed on a plane.

[0157] As shown in FIGS. 34 and 35, the fourth Peltier element unit 60D provided on the scapular portion 15 is formed in a substantially polygonal shape (for example, substantially heptagonal) when viewed from either the upper side Lp or the lower side Lw. As shown in FIGS. 34 and 35, the fourth Peltier element unit 60D includes a main body 71 in which the Peltier element PE is housed, and an annular ring fastener 150 that can be attached from the end side opposite to the heat dissipation surface 61 (cooling surface 61A, heating surface 61B).

[0158] As shown in FIGS. 34 to 35, the main body 71 is composed of a cylindrical small-diameter portion 75, and a large-diameter portion 200 having a bottom surface portion 79 formed in a substantially polygonal shape (for example, substantially heptagonal) and a step surface 76. A heat dissipation surface 61 (cooling surface 61A, heating surface 61B) is formed on the opposite side of the small-diameter portion 75 of the main body 71. As shown in FIG. 36, the main body 71 houses a Peltier element PE and a heat exchange surface 65 that takes in heat by the Peltier element PE and dissipates it into the air for heat exchange. Further, as shown in FIG. 36, the main body 71 houses a blower device 100 that blows the air heat-exchanged by the heat exchange surface 65 to the first opening 75b. The vertical length of the fourth Peltier element unit 60D is 115 mm, the horizontal length is 100 mm, and the height is 30 mm. As shown in FIG. 36, the step surface 76 is fixed to the large-diameter portion 200 with six male threads. As shown in FIG. 36, on the heat exchange surface 65, the cooling fins 65a are arranged in alignment at regular intervals so that the air flowing in from the second opening 72a can pass between the cooling fins 65a. Thereby, since the cooling air flowing in between the cooling fins 65a comes into contact with the cooling fins 65a, the heat of the Peltier element PE can be efficiently exchanged.

[0159] The large-diameter portion 200 has a heat dissipation surface 61, a bottom surface portion 79 formed in a substantially polygonal shape (for example, substantially heptagonal), a side surface portion 72, and a step surface 76 on the small-diameter portion 75 side and extending radially outward in the radial direction RD around the axis AX of the main body 71. As shown in FIG. 36, inside the large-diameter portion 200, a flow guide member 74 is provided for guiding the air flowing in from the second opening 72a toward a plurality of cooling fins 65a as the exhaust fan 101 rotates. The flow guide member 74 according to the third embodiment is made of, for example, synthetic resin fibers excellent in heat resistance and strength such as nylon and polyester.

[0160] The step surface 76 can sandwich the back fabric 3B and the element outer peripheral edge portion 31 facing the sandwiching surface 154 of the outer flange 151, and is formed in a substantially polygonal shape (for example, substantially heptagonal).

[0161] The side surface portion 72 is composed of five side surfaces having five second openings 72a and two side surfaces having ten second openings 72a. The second opening 72a is a hole for allowing the cooled air (for example, 35°C) existing outside the fourth Peltier element unit 60D, that is, inside the temperature control vest 1, to flow into the inside of the main body 71.

[0162] In the small-diameter portion 75, a plurality of first openings 75b are formed on the end surface 75a of the small-diameter portion 75 for allowing the air inside the main body 71 (for example, the air heat-exchanged by the heat exchange surface 65 or the air inhaled from the second opening 72a) to flow out to the outside of the fourth Peltier element unit 60D.

[0163] Of the total surface area obtained by summing up the surface areas of the seven side surface portions 72 according to the third embodiment, the ratio occupied by the total surface area obtained by summing up the surface areas of the 35 second openings 72a is preferably about 50% to about 69%. This is because if the ratio occupied by the total surface area obtained by summing up the surface areas of the 35 second openings 72a exceeds about 69%, the air taken into the main body 71 will be affected by the wind outside the fourth Peltier element unit 60D. As a result, the air flowing in from the second opening 72a will be affected by the wind outside the fourth Peltier element unit 60D and cannot be efficiently discharged from the first opening 75b. On the other hand, if the ratio occupied by the total surface area obtained by summing up the surface areas of the 35 second openings 72a is less than about 50%, the amount of cooling air inhaled from the second opening 72a will decrease, and efficient heat exchange cannot be achieved by the heat exchange surface 65.

[0164] As shown in FIG. 36, a guide rail 66 is provided on the outer peripheral surface of the small-diameter portion 75. The guide rail 66 extends in an arc shape along the circumferential direction CR of the small-diameter portion 75 toward the first opening 75b side. A plurality (for example, 4) of guide rails 66 are provided at different positions in the circumferential direction CR of the small-diameter portion 75. As shown in FIG. 36, mounting groove portions 78 are respectively provided between the plurality of guide rails 66 and the end face 75a of the small-diameter portion 75. The plurality (for example, 4) of mounting groove portions 78 are provided along the circumferential direction CR of the small-diameter portion 75. As shown in FIG. 36, the four guide rails 66 are respectively provided with gaps 77 between adjacent guide rails 66 intermittently. A plurality (for example, 4) of gaps 77 are provided on the outer peripheral surface of the small-diameter portion 75. The guide rails 66 adjacent to each other in the circumferential direction CR are arranged at the same height in the axial direction L. As shown in FIG. 36, the gap 77 is connected to the mounting groove portion 78.

[0165] As shown in FIGS. 36 and 37, each of the plurality of guide rails 66 according to the third embodiment has a sliding surface 68 on the heat dissipation surface 61 side between one end 66a and the other end 66b of each guide rail 66. As shown in FIGS. 36 and 37, a plurality (for example, 4) of regulating portions 67 are arranged on each of the sliding surfaces 68 of the plurality of guide rails 66. Each of the plurality of regulating portions 67 regulates the movement operation of the plurality of protrusions 153 that move along the sliding surface 68 toward the anti-circumferential direction ACR of the main body 71. The regulating portions 67 are intermittently arranged in the order of the first regulating portion 67a ⇒ the second regulating portion 67b ⇒ the third regulating portion 67c ⇒ the fourth regulating portion 67d on the sliding surface 68 connecting one end 66a and the other end 66b of each guide rail 66. Each of the plurality of fourth regulating portions 67d is configured to have a height that the respective plurality of protrusions 153 cannot overcome.

[0166] Next, with reference to FIG. 37, a plurality of guide rails 66 on the outer peripheral surface of the small-diameter portion 75 developed on a plane will be described. As shown in FIG. 37, the plurality of guide rails 66 are inclined toward the side surface portion 72 having the second opening 72a with respect to a plane parallel to the axial direction L along the axial center line AX of the main body 71. All of the plurality of guide rails 66 in the third embodiment are given an inclination angle θ of 3° as an example between one end 66a and the other end 66b on the sliding surface 68. Accordingly, all of the plurality of guide rails 66 in the third embodiment are formed in an inclined manner with a height difference ΔH in the axial direction L between one end 50a and the other end 50b. That is, the inclination angle θ of the sliding surface 68 according to the third embodiment is 3° toward the side surface portion 72 having the second opening 72a with respect to a plane parallel to the axial direction L along the axial center line AX of the main body 71.

[0167] The ring fastener 150 is formed so as to be freely fastened or released at the small-diameter portion 75 which is an end portion on the side opposite to the heat dissipation surface 61 (cooling surface 61A, heating surface 61B). The ring fastener 150 is made of synthetic resin and includes a gripping portion 152 formed in a substantially polygonal shape and an annular outer flange 151. The inner diameter of the ring fastener 150 is larger than the outer diameter of the small-diameter portion 75 but smaller than the length of the outer periphery of the large-diameter portion 200. The ring fastener 150 is formed with a sandwiching surface 154 that sandwiches the back fabric 3B and the element outer peripheral edge portion 31 facing the stepped surface 76.

[0168] On the inner peripheral surface 150a of the ring fastener 150 according to the third embodiment, projections 153 that can be connected to respective ones of the plurality of guide rails 66 are provided. The projections 153 are provided in a plurality (for example, four) at intervals in the circumferential direction CR of the ring fastener 150. The plurality of projections 153 can engage with the restricting portions 67 of the respective guide rails 66. The projections 153 adjacent to each other in the circumferential direction CR are arranged at the same height in the axial direction L. Each of the plurality of projections 122 is formed so as to be able to pass through each of the plurality of gaps 70. One projection 122 engages with one guide rail 66 through the gap 70. The plurality of projections 153 are inclined toward the sandwiching surface 154 with respect to a surface parallel to the sandwiching surface 154 of the outer flange 151, and the inclination angle θ is 3°. Thereby, each of the plurality of projections 153 is easily connectable to each of the plurality of guide rails 66. In the temperature control vest 1 according to the third embodiment, three Peltier element units 60 (the fourth Peltier element unit 60D, the second Peltier element unit 60B, the third Peltier element unit 60C) are mounted on three element mounting portions 30 in the vest body 2.

[0169] The heat dissipation surface 61 is in a state of being exposed to the outside. In the Peltier element unit 60 (Peltier element unit), as shown in FIGS. 34 and 36, a bottom surface portion 79 having the heat dissipation surface 61 and a small-diameter portion 75 having the first opening 75b are arranged on opposite sides of each other. As shown in FIGS. 34 and 36, the bottom surface portion 79 having the heat dissipation surface 61 and the stepped surface 76 are arranged on opposite sides of each other. Here, the heat dissipation surface 61 is made of, for example, aluminum, which is a metal excellent in heat conductivity and the like. By configuring the heat dissipation surface 61 according to the third embodiment with aluminum, it can be made into a three-dimensional shape instead of a flat surface, and can be made into a shape that fits exactly to the body surface BS of the wearer HM.

[0170] As shown in FIG. 36, a small-diameter portion 75, which is an end portion on the side opposite to the heat dissipation surface 61 (cooling surface 61A, heating surface 61B) in the axial direction L along the axial center line AX of the main body 71, is provided.

[0171] As shown in FIG. 36, the air blower 100 of the third embodiment includes an exhaust heat fan 101 that discharges and blows the air inside the main body 71, and an exhaust heat fan drive unit 102 that is controlled by a motor (not shown) that rotates the exhaust heat fan 101. Thereby, the air heat-exchanged by the heat exchange surface 65 is discharged from the first opening 75b by the wind generated by the rotation of the exhaust heat fan 101 when the exhaust heat fan drive unit 102 is driven under the control of the temperature control unit 91.

[0172] For example, as shown in FIG. 32, the temperature control branch line 96A according to the third embodiment is connected to the fourth Peltier element unit 60D. For example, the temperature control branch line 96B is connected to the second Peltier element unit 60B. For example, the temperature control branch line 96C is connected to the third Peltier element unit 60C. However, it is not limited thereto. The temperature control branch lines 96A, 96B, and 96C may be arbitrarily connected under the judgment of the wearer HM by simplifying the wiring path particularly as long as they have a one-to-one connection relationship with the three Peltier element units 60 (the second to fourth Peltier element units 60B, 60C, 60D).

[0173] <Mounting of the Peltier Element Unit 60 of the Third Embodiment> The mounting of the fourth Peltier element unit 60D will be described with reference to FIGS. 38 to 39. FIG. 38 is a cross-sectional view of the fourth Peltier element unit mounted on the temperature control vest according to the third embodiment. FIG. 39 is a cross-sectional view taken along line A-A of FIG. 35. Note that FIG. 39 is a cross-sectional view showing the fourth Peltier element unit 60D in a state where the outer peripheral edge portion 31 of the element and the back fabric 3B are sandwiched between the main body 71 and the ring fastener 150.

[0174] A method of mounting the fourth Peltier element unit 60D on the element mounting portion 30 will be described with reference to FIG. 38. As shown in FIG. 39, when mounting the fourth Peltier element unit 60D, the side of the small-diameter portion 75 of the fourth Peltier element unit 60D is inserted from the inner side 30a of the element mounting portion 30 into the element insertion hole 32 formed in the element mounting portion 30 of the temperature control vest 1 and into the insertion hole 3b of the back fabric 3B. The fourth Peltier element unit 60D is disposed in the element insertion hole 32 and in the insertion hole 3b of the back fabric 3B with the step surface 76 of the fourth Peltier element unit 60D abutted against the element outer peripheral edge portion 31 of the element insertion hole 32.

[0175] Subsequently, the outer flange 151 is brought into contact with the back fabric 3B from the outside of the back fabric 3B. A person inserts the small-diameter portion 75 inside the ring fastener 150 and inserts each of the plurality of protrusions 153 of the ring fastener 150 into each of the plurality of gaps 77. As a result, the back fabric 3B and the element outer peripheral edge portion 31 are in a state of being sandwiched between the stepped surface 76 of the large-diameter portion 200 and the outer flange 151 of the ring fastener 150. Subsequently, the person relatively rotates the main body 71 and the ring fastener 150 in the circumferential direction CR of the small-diameter portion 75, so that each of the protrusions 133 enters the attachment groove portion 69 from one end 66a of the guide rail 66. Then, the person relatively rotates the ring fastener 150 in the circumferential direction CR of the small-diameter portion 75, and each of the plurality of protrusions 153 slides on the sliding surface 68 of each of the guide rails 66 along the circumferential direction CR of the small-diameter portion 75. Further, the person relatively rotates the main body 71 and the ring fastener 150 in the circumferential direction CR of the small-diameter portion 75, and causes each of the plurality of protrusions 153 to overcome each of the plurality of restricting portions 67 provided on the sliding surface 68. When each of the plurality of protrusions 153 has overcome each of the plurality of restricting portions 67, the movement operation of the plurality of restricting portions 67 toward the anti-circumferential direction ACR of the small-diameter portion 75 is restricted by the plurality of restricting portions 67 that have been overcome. Each of the plurality of protrusions 153 whose movement has stopped is fixed by coming into surface contact and engaging with each of the plurality of restricting portions 67 that have been overcome. Therefore, the back fabric 3B and the element outer peripheral edge portion 31 are fixed in a state of being sandwiched between the outer flange 151 and the stepped surface 76 of the large-diameter portion 200. The protrusion 153 according to the third embodiment and the restricting portion 67 of the guide rail 66 can be connected, but do not hit each other such as helical screws that oppose each other. Therefore, the protrusion 153 of the ring fastener 150 and the restricting portion 67 of the guide rail 66 are fixed by engagement, not by screwing.

[0176] The fourth Peltier element unit 60D is mounted on the element mounting portion 30 of the scapular part 15. The surface side of the heat dissipation surface 61 of the fourth Peltier element unit 60D is larger than the surface areas of the heat dissipation surfaces 61 of the second Peltier element unit 60B and the third Peltier element unit 60C. As a result, as shown in FIGS. 32 and 39, the heat dissipation surface 61 (cooling surface 61A or heating surface 61B) can be brought into a state of being in contact with the body side (scapula) of the wearer HM of the temperature control vest 1 itself facing it. Thereby, the heat dissipation surface 61 (cooling surface 61A or heating surface 61B) can be brought into direct or indirect contact with the body surface of the wearer HM itself via a singlet or the like, and the vicinity of the scapula of the wearer HM can be cooled. Further, the cooling surface 61A of the fourth Peltier element unit 60D can cool a wider area of the body surface of the wearer HM itself than the cooling surfaces 61A of the second Peltier element unit 60B and the third Peltier element unit 60C.

[0177] As shown in FIG. 39, in the fourth Peltier element unit 60D, the heat exchange surface 65 having a plurality of cooling fins 65a is provided directly below the blower 100. In the fourth Peltier element unit 60D, a flow guide member 74 is disposed in front of the heat exchange surface 65 on the heat exchange surface 65 side rather than the second opening 72a. The height difference from the bottom surface to the top surface of the flow guide member 74 is configured to be larger than the height difference from the bottom surface of the heat exchange surface 65 to the tip of the cooling fins 65a. Thereby, a large amount of air sucked from the second opening 72a can be guided toward the heat exchange surface 65.

[0178] As shown in FIG. 39, the side surface portion 72 is formed so as to extend straight downward from the outer peripheral end 76a of a stepped surface 76 that is located radially outward in the radial direction RD about the axis AX of the main body 71, relative to one outer diameter end 151a of the outer flange 151, toward the bottom surface portion 79. As shown in FIG. 39, the side surface portion 72 is formed so as to extend straight downward from the other outer peripheral end 76b of the stepped surface 76 that is located radially outward in the radial direction RD about the axis AX of the main body 71, relative to one outer diameter end 151a of the outer flange 151, toward the bottom surface portion 79. Since the flange such as that in Patent Document 1 is in a thin plate shape and is made of a soft material, when the fabric of the cooling clothing is pulled, the sandwiched fabric may be damaged due to the friction of the flange. Further, if the wearer drops the Peltier element unit such as that in Patent Document 1 and the flange of the Peltier element mounting portion is damaged, it becomes difficult to attach the Peltier element unit to the cooling clothing, which is inconvenient for the operator. In the fourth Peltier element unit 60D of the third embodiment, even without a flange on the main body 71, since the rigidity of the main body 71 is high, even when the back fabric 3B and the element outer peripheral edge portion 31 are sandwiched between the main body 71 and the ring fastener 150, the sandwiched fabric is less likely to loosen. Further, even when the fabric of the temperature control vest 1 is pulled, since the rigidity of the main body 71 is strong, the sandwiched fabric is less likely to be damaged due to the friction of the stepped surface 76. Further, even if a person drops the fourth Peltier element unit 60D, it is unlikely that the fourth Peltier element unit 60D cannot be attached to the temperature control vest 1 by sandwiching the back fabric 3B and the element outer peripheral edge portion 31 between the main body 71 and the ring fastener 150. Therefore, the temperature control vest 1 is provided with the fourth Peltier element unit 60D that is easy to use for the wearer.

[0179] <Regarding the thickness of the fabric sandwiched between the stepped surface 76 and the outer flange 151> Using FIGS. 40 to 42, the location where the protrusion 153 and the sliding surface 68 are engaged and fixed by surface contact will be described according to the thickness of the fabric of the temperature control vest 1 sandwiched between the stepped surface 76 and the outer flange 151. FIG. 40 is a side view of the fourth Peltier element unit according to the third embodiment, and is an explanatory diagram showing a case where the guide rail and the outer flange are engaged at the first stage. FIG. 41 is a side view of the fourth Peltier element unit according to the third embodiment, and is an explanatory diagram showing a case where the guide rail and the outer flange are engaged at the second stage. FIG. 42 is a side view of the fourth Peltier element unit according to the third embodiment, and is an explanatory diagram showing a case where the guide rail and the outer flange are engaged at the third stage.

[0180] Using FIG. 40, a case will be described where each of the plurality of protrusions 153 overrides the first regulating portion 67a of each guide rail 66 and the guide rail 66 and the protrusion 153 engage with each other in the first stage. When the thickness of the fabric made of the temperature control vest 1 is X7 (for example, about 3 mm), with the fabric sandwiched between the step surface 76 of the large-diameter portion 200 and the sandwiching surface 154 of the outer flange 151, a person enters the small-diameter portion 75 of the main body 71 inside the ring fastener 150. As a result, each of the protrusions 153 enters each of the gaps 77. Subsequently, when the person relatively rotates the main body 71 and the ring fastener 150 in the circumferential direction CR of the small-diameter portion 75, each of the protrusions 153 of the ring fastener 150 enters the attachment groove portion 78 from one end 66a of the guide rail 66. Further, when the person relatively rotates the main body 71 and the ring fastener 150 in the circumferential direction CR of the small-diameter portion 75, each of the plurality of protrusions 153 slides on the sliding surface 68 of each guide rail 66 along the circumferential direction CR of the small-diameter portion 75. When the main body 71 and the ring fastener 150 are relatively rotated by, for example, 15 degrees along the circumferential direction CR of the main body portion 62, each of the plurality of protrusions 153 overrides each of the plurality of first regulating portions 67a disposed on the sliding surface 68. The movement of each of the protrusions 153 in the anti-circumferential direction ACR is regulated by each of the overridden first regulating portions 67a. The angle by which the main body 71 and the ring fastener 150 are relatively rotated along the circumferential direction CR of the main body 71 for each of the plurality of protrusions 153 to override each of the plurality of first regulating portions 67a is not limited to 15 degrees. For example, it is preferably any one of 15 degrees to 20 degrees.

[0181] As shown in FIG. 40, each of the plurality of protrusions 153 where the movement of the small-diameter portion 75 in the circumferential direction CR has stopped in the first stage is fixed by surface-contact engagement with each of the plurality of first regulating portions 67a. In this case, the fourth Peltier element unit 60D can be attached to the temperature control vest 1 in a state where a fabric having a thickness of X7 (for example, about 3 mm) made of the temperature control vest 1 is sandwiched between the stepped surface 76 of the main body 71 and the sandwiching surface 154 of the outer flange 151. When releasing the attachment of the fourth Peltier element unit 60D, a person relatively rotates the main body 71 and the ring fastener 150 in the anti-circumferential direction ACR of the main body 71, so that each of the plurality of protrusions 153 gets over each of the first regulating portions 67a. Thereby, the Peltier element unit 60 can be detached from the temperature control vest 1. In this case, as an example, the person relatively rotates the main body 71 and the ring fastener 150 by 15 degrees in the anti-circumferential direction ACR of the main body 71.

[0182] Next, with reference to FIG. 41, a case will be described where each of the plurality of protrusions 153 overrides the second restricting portion 67b of each guide rail 66 and the guide rail 66 engages with the protrusion 153 in the second stage. When the thickness of the fabric made of the temperature control vest 1 is X8 (for example, about 2 mm), with the fabric sandwiched between the stepped surface 76 of the main body 71 and the outer flange 151, a person enters the small-diameter portion 75 of the main body 71 inside the ring fastener 150. As a result, each protrusion 153 enters through each gap 77. Subsequently, when the person relatively rotates the main body 71 and the ring fastener 150 in the circumferential direction CR of the small-diameter portion 75, each protrusion 153 of the ring fastener 150 enters from one end 66a of the guide rail 66 into the attachment groove portion 78. Further, when the person relatively rotates the main body 71 and the ring fastener 150 in the circumferential direction CR of the small-diameter portion 75, each of the plurality of protrusions 153 slides on the sliding surface 68 of each guide rail 66 along the circumferential direction CR of the small-diameter portion 75. When the main body 71 and the ring fastener 150 are relatively rotated by, for example, 15 degrees along the circumferential direction CR of the main body portion 62, each of the plurality of protrusions 153 overrides each of the plurality of first restricting portions 67a disposed on the sliding surface 68. The movement of each protrusion 153 in the anti-circumferential direction ACR is restricted by each overridden first restricting portion 67a.

[0183] Furthermore, when the person relatively rotates the main body 71 and the ring fastener 150 by, for example, 15 degrees along the circumferential direction CR of the small-diameter portion 75, each of the plurality of protrusions 153 slides on the sliding surface 68 and overrides each of the plurality of second restricting portions 67b. The movement of each protrusion 153 in the anti-circumferential direction ACR is restricted by each overridden second restricting portion 67b. The angle by which the main body 71 and the ring fastener 150 are relatively rotated along the circumferential direction CR of the main body 71 in order for each of the plurality of protrusions 153 to override each of the plurality of second restricting portions 67b is not limited to 15 degrees. For example, it is preferably either 15 degrees or 20 degrees.

[0184] As shown in Fig. 41, each of the plurality of protrusions 153 where the movement of the small-diameter portion 75 in the circumferential direction CR has stopped at the second stage is fixed by surface contact and engagement with each of the plurality of first restricting portions 67a. In this case, with the fabric having a thickness of X8 (for example, about 2 mm) of the temperature control vest 1 sandwiched between the stepped surface 76 of the main body 71 and the sandwiching surface 154 of the outer flange 151, the fourth Peltier element unit 60D can be attached to the temperature control vest 1. When removing the attachment of the fourth Peltier element unit 60D, a person relatively rotates the main body 71 and the ring fastener 150 in the anti-circumferential direction ACR of the main body 71, so that each of the plurality of protrusions 153 gets over each of the first restricting portion 67a and the second restricting portion 67b. Thereby, the Peltier element unit 60 can be detached from the temperature control vest 1. In this case, the person relatively rotates the main body 71 and the ring fastener 150 in the anti-circumferential direction ACR of the main body 71 by, for example, 30 degrees.

[0185] Next, with reference to FIG. 42, a case will be described in which each of the plurality of protrusions 153 overrides the third regulating portion 67c of each guide rail 66 and the guide rail 66 engages with the protrusion 153 at the third stage. When the thickness of the fabric made of the temperature control vest 1 is X9 (for example, about 1 mm), with the fabric sandwiched between the stepped surface 76 of the main body 71 and the outer flange 151, a person enters the small-diameter portion 75 of the main body 71 inside the ring fastener 150. As a result, each protrusion 153 enters each gap 77. Subsequently, when the person relatively rotates the main body 71 and the ring fastener 150 in the circumferential direction CR of the small-diameter portion 75, each protrusion 153 of the ring fastener 150 enters the attachment groove portion 78 from one end 66a of the guide rail 66. Further, when the person relatively rotates the main body 71 and the ring fastener 150 in the circumferential direction CR of the small-diameter portion 75, each of the plurality of protrusions 153 slides on the sliding surface 68 of each guide rail 66 along the circumferential direction CR of the small-diameter portion 75. When the main body 71 and the ring fastener 150 are relatively rotated by, for example, 15 degrees along the circumferential direction CR of the main body portion 62, each of the plurality of protrusions 153 overrides each of the plurality of first regulating portions 67a disposed on the sliding surface 68. The movement of each protrusion 153 in the anti-circumferential direction ACR is regulated by each overridden first regulating portion 67a.

[0186] Furthermore, when the person relatively rotates the main body 71 and the ring fastener 150 by, for example, 15 degrees along the circumferential direction CR of the small-diameter portion 75, each of the plurality of protrusions 153 slides on the sliding surface 68 and overrides each of the plurality of second regulating portions 67b. The movement of each protrusion 153 in the anti-circumferential direction ACR is regulated by each overridden second regulating portion 67b.

[0187] Furthermore, when a person rotates the main body 71 and the ring fastener 150 relative to each other by, for example, 15 degrees along the circumferential direction CR of the small-diameter portion 75, each of the plurality of protrusions 153 slides on the sliding surface 68 and overrides each of the plurality of third restricting portions 67c. By each of the overridden second restricting portions 67b, the movement of each of the protrusions 153 in the anti-circumferential direction ACR is restricted. The angle by which the main body 71 and the ring fastener 150 are relatively rotated along the circumferential direction CR of the main body 71 in order for each of the plurality of protrusions 153 to override each of the plurality of third restricting portions 67c is not limited to 15 degrees. For example, it is preferably any angle from 15 degrees to 20 degrees.

[0188] As shown in FIG. 42, each of the plurality of protrusions 153 that has stopped moving in the circumferential direction CR of the small-diameter portion 75 at the third stage is fixed by surface-contact engagement with each of the plurality of first restricting portions 67a. In this case, the fourth Peltier element unit 60D can be attached to the temperature control vest 1 in a state where a fabric having a thickness of X9 (for example, about 1 mm) made of the temperature control vest 1 is sandwiched between the stepped surface 76 of the main body 71 and the sandwiching surface 154 of the outer flange 151. When removing the attachment of the fourth Peltier element unit 60D, a person relatively rotates the main body 71 and the ring fastener 150 in the anti-circumferential direction ACR of the main body 71, so that each of the plurality of protrusions 153 overrides each of the first restricting portion 67a to the third restricting portion 67c. Thereby, the Peltier element unit 60 can be detached from the temperature control vest 1. In this case, the person relatively rotates the main body 71 and the ring fastener 150 by, for example, 45 degrees in the anti-circumferential direction ACR of the main body 71.

[0189] When each of the plurality of protrusions 153 overrides the third restricting portion 67c, even if a person relatively rotates the main body 71 and the ring fastener 150 in the circumferential direction CR of the small-diameter portion 75, each of the plurality of protrusions 153 cannot override each of the plurality of fourth restricting portions 67d. Thereby, it is possible to prevent the fourth Peltier element unit 60D from falling off the temperature control vest 1 due to the relative rotation of the main body 71 and the ring fastener 150 in the circumferential direction CR of the small-diameter portion 75.

[0190] When attaching the fourth Peltier element unit 60D according to the third embodiment to the best body 2, first, each of the plurality (for example, 4) of protrusions 153 that make up the protrusions enters the plurality (for example, 4) of gaps 70 in the axial direction L along the axial center line AX of the main body 71. As a result, the stepped surface 76 of the fourth Peltier element unit 60D and the ring fastener 150 sandwich the fabric of the temperature control vest 1. Subsequently, the main body 71 and the ring fastener 150 are relatively rotated, and in a state where the stepped surface 76 of the fourth Peltier element unit 60D and the ring fastener 150 sandwich the fabric of the temperature control vest 1, each of the plurality of protrusions 153 has its movement restricted by the overridden restricting portion 67. Furthermore, by each of the plurality of protrusions 153 engaging with each of the plurality of restricting portions 54, the blower unit 40 is attached to the temperature control vest 1. Therefore, a person can attach the fourth Peltier element unit 60D to the temperature control vest 1 with a one-touch operation, and can attach the Peltier element unit 60 to the temperature control vest 1. Furthermore, as the main body 71 and the ring fastener 150 are relatively rotated, the engagement positions with each of the plurality of protrusions 153 can be changed step by step. As a result, for example, if the thickness of the fabric of the temperature control vest 1 is about 3 mm, the plurality of protrusions 153 engage with the first restricting portion 67a, and the fourth Peltier element unit 60D can be attached to the temperature control vest 1. For example, if the thickness of the fabric of the temperature control vest 1 is about 2 mm, the plurality of protrusions 153 engage with the second restricting portion 67b, and the fourth Peltier element unit 60D can be attached to the temperature control vest 1. For example, if the thickness of the fabric of the temperature control vest 1 is about 1 mm, the plurality of protrusions 153 engage with the third restricting portion 67c, and the fourth Peltier element unit 60D can be attached to the temperature control vest 1. Therefore, regardless of the thickness of the fabric of the temperature control vest 1, a person can attach the fourth Peltier element unit 60D to the temperature control vest 1 corresponding to that thickness. Therefore, it becomes easy to attach the fourth Peltier element unit 60D according to the third embodiment to the fabric of the temperature control vest 1, and the usability of the temperature control vest 1 can be improved. Furthermore, even if the back fabric 3B and the element mounting portion 30 are sandwiched many times between the stepped surface 76 of the main body 71 and the ring fastener 150, it is possible to make it difficult for the back fabric 3B and the element mounting portion 30 to plastically deform.Therefore, even if the fourth Peltier element unit 60D is attached to the temperature control vest 1, rattling can be prevented, and damage to the back fabric 3B and the element mounting portion 30 can be avoided.

[0191] <Regarding the flow of air inhaled from the second opening 72a> With reference to FIGS. 43 to 44, the influence of the rotation of the exhaust heat fan 101 on the flow of air flowing in from the second opening 72a will be described. FIG. 43 is a schematic diagram showing the influence of the rotation of the exhaust heat fan on the air flowing in from the second opening of the fourth Peltier element unit of the comparative example. FIG. 44 is a schematic diagram showing the influence of the rotation of the exhaust heat fan on the air flowing in from the second opening of the fourth Peltier element unit of the third embodiment.

[0192] As shown in FIGS. 43 to 44, the cooling fins 65a according to the comparative example and the third embodiment are spaced at regular intervals so that the air flowing in from the air holes 64a can pass between the cooling fins 65a. As shown in FIGS. 43 to 44, the cooling fins 65a according to the comparative example and the third embodiment are arranged in an array of 12 in the vertical row and 6 in the horizontal row. Thereby, the cooling air flowing between the cooling fins 65a is likely to come into contact with the cooling fins 65a, so that the heat of the Peltier element PE can be efficiently exchanged.

[0193] As shown in FIGS. 43 to 44, the blower device 100 is provided directly above the heat exchange surface 65 in the main body 71 according to the comparative example and the third embodiment. A part of the air inhaled from the second opening 72a is lifted in the rotation direction KR of the exhaust heat fan 101 by the wind generated by the rotation of the exhaust heat fan 101, and is moved toward the first opening 75b and discharged from the first opening 75b.

[0194] As shown in FIGS. 43 to 44, inside the main body 71 according to the comparative example and the third embodiment, there is an internal space NB between the side surface portion 72 of the fourth Peltier element unit 60D and the heat exchange surface 65. In the internal space NB inside the main body 71 in the comparative example, that is, around the heat exchange surface 65, a flow guiding member 74 for guiding the air inhaled from the second opening 72a to the heat exchange surface 65 is not provided. On the other hand, in the internal space NB inside the main body 71 according to the third embodiment, that is, around the heat exchange surface 65, a flow guiding member 74 for guiding the air inhaled from the second opening 72a to the heat exchange surface 65 is provided.

[0195] First, with reference to FIG. 43, the influence of the air flowing in from the second opening 72a of the fourth Peltier element unit 60D of the comparative example due to the rotation of the exhaust heat 101 will be described. As shown in FIG. 43, in the fourth Peltier element unit 60D of the comparative example, a part (AR8, AR12, AR13) of the air AR inhaled from the second opening 72a comes into contact with the cooling fins 65a and undergoes heat exchange. Among the heat-exchanged air AR (AR8, AR12, AR13), the air AR8 is moved toward the first opening 75b by the wind generated by the rotation of the exhaust heat fan 101 in the rotation direction KR and is discharged from the first opening 75b. On the other hand, the heat-exchanged air AR12 and air AR13 remain in the internal space NB as they are. As a result, it obstructs the movement of the newly inhaled air AR from the second opening 72a, and the air discharge efficiency from the first opening 75b deteriorates.

[0196] As shown in FIG. 43, a part (AR9, AR10, AR11, AR14) of the air AR inhaled from the second opening 72a does not move toward the heat exchange surface 65 and remains in the internal space NB. As a result, a part of the air AR inhaled from the second opening 72a stays in the main body 71 without going toward the heat exchange surface 65, and the air discharge efficiency from the first opening 75b deteriorates.

[0197] Next, the flow guiding member 74 will be described. In the fourth Peltier element unit 60D according to the third embodiment, 30 flow guiding members 74 are provided in the internal space NB between the side surface portion 72 and the heat exchange surface 65 of the fourth Peltier element unit 60D. As shown in FIG. 44, the flow guiding members 74 are provided radially around the axis line AX of the blower 100. The flow guiding member 74 is formed in an arc shape that curves in the same direction as the rotation direction KR of the exhaust heat fan 101 toward the heat exchange surface 65. Thereby, as shown in FIG. 44, a part (AR15 to AR21) of the air AR sucked from the second opening 72a is changed to flow in the same direction as the rotation direction KR of the exhaust heat fan 101 by contacting the flow guiding member 74. That is, the flow guiding member 74 has a function of changing a part (AR15 to AR21) of the air AR sucked from the second opening 72a to flow in the same direction as the rotation direction KR of the exhaust heat fan 101 by bringing it into contact with the flow guiding member 74. Further, by providing the flow guiding member 74 in the internal space NB, the suction resistance for the air AR sucked from the second opening 72a is reduced, so that the cooling air can be efficiently taken into the main body 71 from the second opening 72a.

[0198] Next, with reference to FIG. 44, the influence of the air flowing in from the second opening 72a of the fourth Peltier element unit 60D of the third embodiment due to the rotation of the exhaust heat 101 will be described. As shown in FIG. 44, a part (AR15 to AR21) of the air AR sucked from the second opening 72a contacts the flow guiding member 74 and is guided to flow in the same direction as the rotation direction KR of the exhaust heat fan 101. Subsequently, a part of the air AR contacts the cooling fins 65a and undergoes heat exchange. The air that has undergone heat exchange is moved toward the first opening 75b while being lifted in the rotation direction KR of the exhaust heat fan 101 by the rotation of the exhaust heat fan 101, and is discharged from the first opening 75b. When the flow guiding member 74 is disposed in the main body 71 according to the third embodiment, the ratio of the air sucked from the second opening 72a to be discharged from the first opening 75b can be increased by about 10% compared to the case where the flow guiding member 74 is not disposed in the main body 71 of the comparative example.

[0199] Next, the operation and effects of the fourth Peltier element unit 60D and the temperature control vest 1 according to the third embodiment will be described.

[0200] The fourth Peltier element unit 60D is detachable from the element insertion hole 32 formed in the fabric forming the temperature control vest 1 according to the third embodiment, has a Peltier element PE, and has a heat exchange surface 65 formed on the opposite side of the cooling surface 61A or the heating surface 61B. In the fourth Peltier element unit 60D, the fourth Peltier element unit 60D includes a main body 71 that houses the Peltier element PE, and a ring fastener 150 that can be attached from the end side opposite to the cooling surface 61A or the heating surface 61B. The main body 71 is composed of a small-diameter portion 75 and a large-diameter portion 200. The cooling surface 61A or the heating surface 61B is formed on the opposite side of the small-diameter portion 75. The small-diameter portion 75 has a first opening 75b formed in the end surface 75a of the small-diameter portion 75 for allowing air to flow out of the main body 71. The large-diameter portion 200 has a side surface portion 72 formed. A stepped surface 76 extending radially outward around the axial center line AX of the main body 71 is formed on the side of the small-diameter portion 75. The side surface portion 72 has a second opening 72a formed in the end surface of the side surface portion 72 for allowing air to flow into the main body 71. The stepped surface 76 is formed from the outer peripheral end thereof toward the heat dissipation surface 61 (cooling surface 61A, heating surface 61B). The ring fastener 150 has a sandwiching surface 154 formed for sandwiching the stepped surface 76 and the fabric of the temperature control vest 1.

[0201] According to this aspect, in the fourth Peltier element unit 60D, it is detachable from the element insertion hole 32 formed in the fabric that forms the temperature control vest 1, has a Peltier element PE, and a heat exchange surface 65 is formed on the side opposite to the heat dissipation surface 61. The fourth Peltier element unit 60D is composed of a main body 71 that houses the Peltier element PE and a ring fastener 150 that can be attached from the end side opposite to the heat dissipation surface 61. The heat dissipation surface 61 formed on the side opposite to the small-diameter portion 75 of the main body 71 cools or warms the body of the wearer. A stepped surface 76 that extends radially outward around the axis AX of the main body 71 is formed on the large-diameter portion 200 of the main body 71 on the side of the small-diameter portion 75. A side surface portion 72 formed on the large-diameter portion 200 has a second opening 72a for allowing air to flow into the main body 71 and is formed from the outer peripheral end of the stepped surface 76 toward the heat dissipation surface 61. The ring fastener 150 has a clamping surface 154 for clamping the fabric that forms the temperature control vest 1 with the stepped surface 76. Thus, even if the fabric of the temperature control vest 1 is clamped between the stepped surface 76 of the large-diameter portion 200 and the clamping surface 154 of the ring fastener 150, since the rigidity of the main body 71 is high, it is possible to prevent the fabric clamped by the stepped surface 76 from being damaged. Further, by clamping the fabric of the temperature control vest 1 between the stepped surface 76 of the main body 71 and the clamping surface 154 of the ring fastener 150, the fourth Peltier element unit 60D can be attached to the temperature control vest 1. Thereby, a crisis situation where a person cannot attach the fourth Peltier element unit 60D to the temperature control vest 1 even if the fourth Peltier element unit 60D is dropped can be avoided. Therefore, it is possible to prevent damage to the back fabric 3B and the element mounting portion 30 to which the fourth Peltier element unit 60D is attached. Further, it is possible to provide the fourth Peltier element unit 60D that improves the usability of the temperature control vest 1, and the temperature control vest 1 equipped with the fourth Peltier element unit 60D.

[0202] Also, in the fourth Peltier element unit 60D according to the third embodiment, the ring fastener 150 has an annular outer flange 151 that projects outward of the ring fastener 150.

[0203] According to this aspect, the ring fastener 150 has an annular outer flange 151 that projects outward from the ring fastener 150, but the main body 71 does not have a flange. Thus, even when only the ring fastener 150 has a flange, since the rigidity of the main body 71 is high, it is possible to appropriately prevent the fabric sandwiched by the stepped surface 76 from being damaged. Furthermore, the fourth Peltier element unit 60D can be attached by sandwiching the fabric of the temperature control vest 1 between the flange of the main body 71 and the ring fastener 150.

[0204] Also, in the fourth Peltier element unit 60D according to the third embodiment, the heat exchange surface 65 has cooling fins 65a, and the fourth Peltier element unit 60D is provided with an exhaust heat fan 101 for sending wind to let the air in the main body 71 flow out from the first opening 75b. The main body 71 houses the heat exchange surface 65 therein, and a flow guiding member 74 is formed around the heat exchange surface 65 to guide the air flowing in from the second opening 72a toward the cooling fins 65a as the exhaust heat fan 101 rotates.

[0205] According to this aspect, the air that has been heat-exchanged by contacting the cooling fins 65a can be made to flow out from the first opening 75b by the exhaust heat fan 101 provided in the fourth Peltier element unit 60D. The cooling air flowing in from the second opening 72a can be guided toward the cooling fins 65a as the exhaust heat fan 101 rotates by the flow guiding member 74 formed around the heat exchange surface 65. Thereby, the cooling air flowing in from the second opening 72a is guided toward the cooling fins 65a as the exhaust heat fan 101 rotates. Therefore, it is possible to efficiently bring the cooling air in the main body 71 into contact with the cooling fins 65a, make the heat-exchanged air flow out from the first opening 75b, and enhance the cooling efficiency of the fourth Peltier element unit 60D.

[0206] Also, in the fourth Peltier element unit 60D according to the third embodiment, the flow guiding member 74 extends in an arc shape toward the heat exchange surface 65.

[0207] According to this aspect, the flow guiding member 74 formed around the heat exchange surface 65 extends in an arc shape toward the heat exchange surface 65, so that the cooling air flowing in from the second opening 72a can contact the flow guiding member 74 and be guided toward the cooling fins 65a. Thereby, the amount of the cooling air flowing in from the second opening 72a and guided to the cooling fins 65a along with the rotation of the exhaust heat fan 101 can be increased, and it can be made easier for the cooling air to contact the cooling fins 65a.

[0208] Also, in the fourth Peltier element unit 60D according to the third embodiment, the flow guiding member 74 restricts the air flowing in from the second opening 72a from staying around the heat exchange surface 65.

[0209] According to this aspect, the flow guiding member 74 around the heat exchange surface 65 can restrict the cooling air flowing in from the second opening 72a from staying around the heat exchange surface 65 without flowing toward the cooling fins 65a. Thereby, it is possible to prevent the cooling air flowing in from the second opening 72a from staying around the heat exchange surface 65, and the cooling efficiency of the fourth Peltier element unit 60D can be further enhanced.

[0210] Also, in the fourth Peltier element unit 60D according to the third embodiment, on the outer peripheral surface of the small-diameter portion 75, a plurality of guide rails 66 extending in an arc shape along the outer peripheral surface of the small-diameter portion 75 are provided between one end and the other end. The ring fastener 150 has a plurality of protrusions 153 that can be connected to the plurality of guide rails 66. Each of the plurality of guide rails 66 is intermittently provided with a plurality of restricting portions 67 that restrict the movement operation of the protrusions 153 on a sliding surface 68 connecting the one end 66a and the other end 66b. The plurality of restricting portions 67 include a first restricting portion 67a and a second restricting portion 67b provided on the other end 66b side of the first restricting portion 67a. A plurality of gaps 77 extending in the axial direction of the main body 71 are provided between the plurality of guide rails 66. The attachment of the fourth Peltier element unit 60D to the fabric is performed by causing each protrusion 153 constituting the plurality of protrusions 153 to enter the respective gaps 77 constituting the plurality of gaps 77 in the axial direction of the main body 71, sandwiching the fabric between the main body 71 and the ring fastener 150, relatively rotating the main body 71 and the ring fastener 150, and engaging each protrusion constituting the plurality of protrusions 153 with the first restricting portion 67a or the second restricting portion 67b in a state where the fabric is sandwiched between the main body 71 and the ring fastener 150.

[0211] According to this aspect, the attachment of the fourth Peltier element unit 60D is performed by a person causing each protrusion 153 constituting the plurality of protrusions 153 to enter the respective intervals 77 constituting the plurality of gaps 77 in the axial direction of the main body 71 and sandwiching the fabric between the main body 71 and the ring fastener 150. Subsequently, the person relatively rotates the main body 71 and the ring fastener 150, and in a state where the fabric is sandwiched between the main body 71 and the ring fastener 150, each of the plurality of protrusions 153 of the ring fastener 150 crosses each of the plurality of restricting portions 67. As a result, the movement operation is restricted by the restricting portion 67, and the restricting portion 67 and the protrusion 153 are engaged. Thereby, a person can attach the fourth Peltier element unit 60D to the fabric forming the temperature control vest 1 with a one-touch operation with a sense of moderation. Therefore, since loosening or tightening failure of the ring fastener 150 does not occur, it is possible to avoid the fourth Peltier element unit 60D falling off from the temperature control vest 1 or only the ring fastener 150 being lost.

[0212] Further, in the fourth Peltier element unit 60D according to the third embodiment, each of the plurality of guide rails 66 is formed in an inclined manner with a height difference in the axial direction of the main body 71 between one end 66a and the other end 66b.

[0213] According to this aspect, when the fabric forming the temperature control vest 1 is thick, with the main body 71 and the ring fastener 150 sandwiching the fabric, each of the protrusions 153 constituting the plurality of protrusions 153 is engaged with the first restricting portion 67a. On the other hand, when the fabric forming the temperature control vest 1 has no thickness, with the main body 71 and the ring fastener 150 sandwiching the fabric, each of the protrusions 153 constituting the plurality of protrusions 153 is engaged with the second restricting portion 67b. Thereby, regardless of the thickness of the fabric of the temperature control vest 1, the fourth Peltier element unit 60D can be mounted in a state where the fabric is firmly sandwiched between the main body 71 and the ring fastener 150 so as not to fall off from the temperature control vest 1. Further, even when each of the protrusions 153 constituting the plurality of protrusions 153 is engaged with the first restricting portion 67a or the second restricting portion 67b in a state where the fabric of the temperature control vest 1 is sandwiched between the main body 71 and the ring fastener 150, it is difficult for the outer peripheral edge portion 31 of the element to undergo plastic deformation. Therefore, it is possible to prevent the fourth Peltier element unit 60D mounted on the temperature control vest 1 from rattling or the fabric of the temperature control vest 1 from being damaged.

[0214] Further, the temperature control vest 1 is formed by detachably mounting the fourth Peltier element unit 60 according to the third embodiment on the temperature control vest 1.

[0215] According to this aspect, it is possible to provide the fourth Peltier element unit 60D and the temperature control vest 1 that can prevent damage to the fabric of the temperature control vest 1 to which the fourth Peltier element unit 60D according to the present disclosure is attached and can improve the usability of the temperature control vest 1.

[0216] As described above, although the present disclosure has been described in accordance with the embodiments, the present disclosure is not limited to the above embodiments, and can be appropriately modified and applied without departing from the gist thereof.

[0217] In the above-described third embodiment, the side surface portion 72 was formed so as to extend straight downward from the outer peripheral ends (one end 76a and the other end 76b) of the stepped surface 76 toward the bottom surface portion 79 (see FIG. 39). However, the present invention is not limited to this. For example, the side surface portion 72 may be formed so as to extend from the outer peripheral ends (one end 76a and the other end 76b) of the stepped surface 76 radially outward in the radial direction RD about the axial center line AX of the main body 71 and toward the bottom surface portion 79. Additionally, for example, the side surface portion 72 may be formed so as to extend from the outer peripheral ends (one end 76a and the other end 76b) of the stepped surface 76 toward the bottom surface portion 79 while bending radially outward in the radial direction RD about the axial center line AX of the main body 71.

[0218] In the above-described third embodiment, the side surface portion 72 was formed so as to extend straight downward from the outer peripheral one end 76a of the stepped surface 76, which is located radially outward in the radial direction RD about the axial center line AX of the main body 71 than the outer diameter one end 151a of the outer flange 151, toward the bottom surface portion 79 (see FIG. 39). The side surface portion 72 was formed so as to extend straight downward from the outer peripheral other end 76b of the stepped surface 76, which is located radially outward in the radial direction RD about the axial center line AX of the main body 71 than the outer diameter other end 151b of the outer flange 151, toward the bottom surface portion 79 (see FIG. 39). However, the present invention is not limited to this. For example, the side surface portion 72 may have a configuration in which the lengths of the outer diameter ends (151a, 151b) of the outer flange 151 and the outer peripheral ends (one end 76a and the other end 76b) of the stepped surface 76 are the same. With this configuration, in a state where the element outer peripheral edge portion 31 and the back fabric 3B are sandwiched between the main body 71 and the ring fastener 150, the side surface portion 72 may be formed so as to extend straight downward from the outer peripheral ends (one end 76a and the other end 76b) of the stepped surface 76 toward the bottom surface portion 79. Further, in the case of this configuration, for example, the side surface portion 72 may be formed so as to extend radially outward in the radial direction RD about the axial center line AX of the main body 71 and toward the bottom surface portion 79 from the outer peripheral ends (one end 76a and the other end 76b) of the stepped surface 76. Additionally, according to this configuration, for example, the side surface portion 72 may be formed so as to extend from the outer peripheral ends (one end 76a and the other end 76b) of the stepped surface 76 toward the bottom surface portion 79 while bending radially outward in the radial direction RD about the axial center line AX of the main body 71.

[0219] The ring fastener 150 of the above-described third embodiment had an outer flange 151. However, it is not limited thereto. For example, the ring fastener 150 may be configured not to have an outer flange 151. Since the rigidity of the main body 71 is high, even if the ring fastener 150 does not have an outer flange 151, the fourth Peltier element unit 60D can be attached to the temperature control vest 1 by sandwiching it between the stepped surface 76 of the main body 71 and the sandwiching surface 154 of the ring fastener 150. Furthermore, since neither the main body 71 nor the ring fastener 150 has a flange, it is possible to prevent the fabric sandwiched between the main body 71 and the ring fastener 150 from being damaged due to the friction of the flanges of both.

[0220] The stepped surface 76 of the above-described third embodiment was formed in a substantially polygonal shape (for example, a substantially heptagonal shape). However, it is not limited thereto. For example, the stepped surface 76 may be formed in a round shape or in a polygonal shape other than a substantially heptagonal shape. However, when the shape of the stepped surface 76 is polygonal, it is possible to prevent the fabric sandwiched between the stepped surface 76 and the sandwiching surface 154 from being caught on the corners of the stepped surface 76 and being pulled to cause wrinkles.

[0221] In the above embodiment, the number of protrusions (protrusions 113, 122, 153) was 4. However, it is not limited thereto. For example, the number of protrusions (protrusions 113, 122, 153) may be 3 or less, or may be 5 or more. However, it is preferable that the number of protrusions (protrusions 113, 122, 153) is the same as the number of guide rails (guide rails 50, 66). This is because if the number of protrusions (protrusions 113, 122, 153) and the number of guide rails (guide rails 50, 66) are different, it becomes difficult to attach the body temperature control device (blower unit 40, Peltier element unit 60) to the temperature control vest 1.

[0222] In the above embodiment, the number of guide rails (guide rails 50 and 66) was 4. However, the present invention is not limited to this. For example, the number of guide rails (guide rails 50 and 66) may be 3 or less, or may be 5 or more. However, it is preferable that the number of guide rails (guide rails 50 and 66) is the same as the number of protrusions (protrusions 113, 122, and 153). This is because if the number of protrusions (protrusions 113, 122, and 153) is different from the number of guide rails (guide rails 50 and 66), it will be difficult to attach the body temperature adjustment device (blower unit 40 and Peltier element unit 60) to the temperature control vest 1.

[0223] In the above embodiment, the number of restricting portions (restricting portions 54 and 67) provided on each of the plurality of sliding surfaces (sliding surfaces 53 and 68) was 4. However, the present invention is not limited to this. For example, the number of restricting portions (restricting portions 54 and 67) provided on each of the plurality of sliding surfaces (sliding surfaces 53 and 68) may be 3 or less, or may be 5 or more.

[0224] In the above embodiment, the number of gaps (gaps 51, 70, and 77) was 4. However, the present invention is not limited to this. For example, the number of gaps (gaps 51, 70, and 77) may be 3 or less, or may be 5 or more.

[0225] In the above-described embodiment, when the plurality of guide rails (guide rails 50 and 66) were deployed on a plane, the inclination angle θ of each guide rail between one end (one end 50a, one end 66a) and the other end (the other end 50b, the other end 66b) was 3°. However, it is not limited to this. For example, for all of the plurality of guide rails, the inclination angle θ between one end and the other end on the sliding surface (sliding surface 53, sliding surface 68) may be less than 3° or may exceed 3°. However, if the inclination angle θ is less than 1°, there will be no height difference between one end and the other end of the guide rail, so it cannot correspond to the thicknesses of various fabrics, which is not preferable. On the other hand, if the inclination angle θ is 10 degrees or more, it becomes difficult to sandwich the fabric of the temperature control vest 1 and attach it to the temperature control vest 1, which is not preferable.

[0226] In the above-described embodiment, when the plurality of guide rails (guide rails 50 and 66) were deployed on a plane, they were in a straight line between one end (one end 50a, one end 66a) and the other end (the other end 50b, the other end 66b). However, it is not limited to this. For example, when the plurality of guide rails (guide rails 50 and 66) are deployed on a plane, the inclination angle θ of the guide rail from one end to the first restricting portion (first restricting portion 54a, first restricting portion 67a) may be, for example, 5°. In this case, for example, when the plurality of guide rails are deployed on a plane, the inclination angle θ of the guide rail from the first restricting portion to the second restricting portion (second restricting portion 54b, second restricting portion 67b) may be 2°. Further, for example, when the plurality of guide rails are deployed on a plane, the inclination angle θ of the guide rail from the second restricting portion to the third restricting portion (third restricting portion 54c, third restricting portion 67c) may be 1°. As a result, when the plurality of guide rails are deployed on a plane, a configuration is formed in which a parabola is drawn between one end and the other end. Therefore, the amount of movement of each of the plurality of protrusions can be reduced more when the plurality of protrusions reach from the first restricting portion to the third restricting portion than when the plurality of protrusions reach from one end to the first restricting portion.

[0227] In the above-described embodiment, the restricting portions (restricting portion 54, restricting portion 67) were provided on the sliding surfaces (sliding surface 53, sliding surface 68) having 3° on the intake portion (outer case portion 46, air cylinder portion 64) side. However, the present invention is not limited to this. For example, the plurality of guide rails (guide rail 50, guide rail 66) may be arc-shaped along the outer peripheral surface of the main body portion (main body portion 41, main body portion 62) and may extend in a stepped manner.

[0228] In the above-described embodiment, the number of the blowing units 40 attached to the vest main body 2 may be two or more, and is not limited to the embodiment, and can be variously changed. Further, the number of the Peltier element units 60 attached to the vest main body 2 may be two or less, or may be four or more, and is not limited to the embodiment, and can be variously changed.

[0229] In the above-described embodiment, the inclination angles θ of the front surface 63a and the back surface 63b of the inner flange 63 and the inclination angles θ of the front surface 121a and the back surface 121b of the outer flange 121 were 20°. However, the present invention is not limited to this. For example, the inclination angle θ of the front surface 63a and the back surface 63b of the inner flange 63 in the above-described embodiment can be appropriately changed as long as it is 15° or more and 30° or less. The inclination angle θ of the front surface 121a and the back surface 121b of the outer flange 121 can be appropriately changed as long as it is 15° or more and 30° or less. Note that if the inclination angle θ of the inner flange 63 is less than 15°, it becomes difficult to change the flow of the air flowing into the air holes 64a by the inner flange 63 so as to be directed toward the base of the cooling fins 65a, which is not preferable. On the other hand, if the inclination angle θ of the inner flange 63 and the inclination angle θ of the outer flange 121 exceed 30°, the element outer peripheral edge portion 31 of the element mounting portion 30 is excessively bent in the vicinity of the end portion on the radially outer side of the inner flange 63 and the outer flange 121. This may cause damage to the element outer peripheral edge portion 31 or the like, which is not preferable.

[0230] In the above embodiment, the inclination angles θ of the front surface 63a and the back surface 63b of the inner flange 63 and the inclination angles θ of the front surface 121a and the back surface 121b of the outer flange 121 were 20°. However, the present invention is not limited to this. For example, a configuration may be adopted in which the inclination angles θ of the front surface 121a and the back surface 121b of the outer flange 121 are larger than the inclination angles θ of the front surface 63a and the back surface 63b of the inner flange 63. With this configuration, when the Peltier element unit 60 is mounted on the element mounting portion 30, a part of the front surface 63a of the inner flange 63 comes into contact (for example, line contact or point contact) with the element mounting portion 30. Therefore, the contact area between the element mounting portion 30 and the front surface 63a of the inner flange 63 becomes smaller than that in the above embodiment, and thus the surface pressure of the contact surface increases. Therefore, it is possible to more effectively prevent the Peltier element unit 60 from coming off the element mounting portion 30 than when the front surface 63a of the inner flange 63 and the front surface 121a of the outer flange 121 are in surface contact with the element mounting portion 30.

[0231] In the above embodiment, the drive unit 33 drives the motor based on 5V output from the portable battery 84 to rotate the propeller-type fan 42. However, the present invention is not limited to this. For example, a battery capable of supplying a voltage exceeding 5V may be provided, and the drive unit 33 may drive the motor to rotate based on the voltage output from the battery.

[0232] In the above embodiment, the blowing unit 40 was provided in the temperature control vest 1, but the present invention is not limited to this. For example, a configuration may be adopted in which the blowing unit 40 is not provided in the temperature control vest 1, and it can be changed as appropriate.

[0233] In the above-described embodiment, in the Peltier element, the temperature of the cooling surface under endothermic conditions was set to about 10°C as an example. However, it is not limited to such a temperature. For example, it may be a temperature range higher than 0°C and close to 10°C, and the endothermic characteristics of the Peltier element can be appropriately changed. Similarly, the temperature of the heating surface under exothermic conditions was set to about 30-something °C as an example. However, it is not limited to such a temperature. For example, it may be a temperature slightly higher than body temperature and around 40°C that does not cause burns, and the exothermic characteristics of the Peltier element can be appropriately changed.

[0234] In the above-described embodiment, the best body 2 in which the element mounting portions 30 are provided at three locations in total on the back side clothing 3B of the clothing 3 was cited. However, it is not limited thereto. The number, arrangement position, and arrangement method of the element mounting portions provided on the clothing can be appropriately changed according to the use of the body temperature adjustment clothing (product) according to the present disclosure, the physique of the wearer, etc., and the specifications of the product.
