Description

[Technical Field]

[0001] The present disclosure relates to a Peltier element unit capable of adjusting body temperature using a Peltier element, and a body temperature adjustment garment capable of wearing a Peltier element unit. [Background technology]

[0002] In recent years, there have been many extremely hot days throughout the year that are uncomfortable for people. On such extremely hot days, measures to prevent heatstroke, such as frequent hydration and moderate use of air conditioners, are recommended. However, due to reasons such as the lack of air conditioners or insufficient air conditioning, workers working outdoors in extremely hot weather, workers working in humid indoor environments, and people participating in recreational activities, sports, or watching games under the blazing sun cannot cool down with air conditioners. Therefore, in order to solve this problem, various clothing has been developed in recent years. One example is disclosed in Patent Document 1.

[0003] Patent Document 1 discloses body temperature regulating clothing that has a Peltier element and is attached via an insertion hole into which the Peltier element unit is inserted. The Peltier element unit has a heat transfer surface that absorbs heat from one side of the Peltier element and transfers the heat, and a heat dissipation surface that dissipates heat generated on the other side of the Peltier element. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Japanese Patent Application Publication No. 2023-92711 Summary of the Invention [Problem to be solved by the invention]

[0005] The technology disclosed in Patent Document 1, for example, has the following problems. For example, if a malfunction occurs in a Peltier element unit such as that disclosed in Patent Document 1, and the Peltier element is unable to properly absorb heat and transfer it to the heat transfer surface, the heat transfer surface will not cool, and the body of a worker wearing body temperature regulating clothing will not be properly cooled. Furthermore, for example, there is no way for people around a worker wearing body temperature regulating clothing such as that disclosed in Patent Document 1 to confirm that the heat transfer surface is being cooled. Therefore, for example, if a worker is in a dark, humid indoor environment, and people around the worker do not notice that the heat transfer surface of the Peltier element unit such as that disclosed in Patent Document 1 is not cooling the worker's body, there is a risk that the worker will suffer from heatstroke.

[0006] The present disclosure has been made to solve the above-mentioned problems, and aims to provide a Peltier element unit that makes it easy to confirm when the heat transfer surface is being cooled by heat absorption on one side of the Peltier element, thereby avoiding the risk of heatstroke for workers working in dark, humid indoor environments. [Means for solving the problem]

[0007] In one aspect of the present disclosure made to solve the above problems, a Peltier element unit includes a Peltier element, a heat transfer surface that transfers heat absorbed by one surface of the Peltier element when current is applied, and an operation unit, the Peltier element unit includes a control unit that performs electrical control using the operation unit, a storage unit that stores the Peltier element, a heat exchange surface on the opposite side of the heat transfer surface, an intake hole that takes in air from outside the storage unit, and an exhaust hole that exhausts the air taken in through the intake hole to the outside of the storage unit, a light-emitting unit disposed inside the storage unit, and the control unit enables the light-emitting unit to emit light when the heat transfer surface is cooled by heat absorption by the one surface.

[0008] According to this aspect, when the heat transfer surface is cooled by heat absorption on one side of the Peltier element, the light emitted by the light-emitting unit can be seen from the exhaust hole. This makes it easier for people around the person using the Peltier element unit to confirm that the heat transfer surface is being cooled by the light emitted by the light-emitting unit, for example, in a dark, humid indoor environment. Therefore, a Peltier element unit can be provided in which the light emitted by the light-emitting unit makes people around the person using the Peltier element unit aware that the heat transfer surface is being cooled, thereby preventing the risk of heatstroke for workers working in a dark, humid indoor environment.

[0009] In the above aspect, it is preferable that the heat generated on the one surface is transferred to the heat transfer surface by applying current, and that the control unit is capable of causing the light emitting unit to emit light in a first light emitting mode when the heat transfer surface is cooled by heat absorption on the one surface, and is capable of causing the light emitting unit to emit light in a second light emitting mode different from the first light emitting mode when the heat transfer surface is heated by heat generation on the one surface.

[0010] The light-emitting mode according to the present disclosure is a general term meaning the manner or state in which the light-emitting unit emits light. For example, the light-emitting color of the light-emitting unit may be different between the first and second light-emitting modes, the light-emitting unit may be continuously lit or flashing between the first and second light-emitting modes, or the light-emitting time of the light-emitting unit may be different between the first and second light-emitting modes.

[0011] According to this aspect, when the heat transfer surface is cooled due to heat absorption by one surface of the Peltier element, the light emitted by the light-emitting unit in the first light-emitting mode can be seen from the exhaust hole. As a result, for example, if a person using the Peltier element unit is in a dark, humid indoor environment, the light emitted from the exhaust hole in the first light-emitting mode can inform people around the person that the heat transfer surface is being cooled. On the other hand, when the heat transfer surface is heated due to heat generated by one surface of the Peltier element, the light emitted by the light-emitting unit in the second light-emitting mode can be seen from the exhaust hole. As a result, for example, if a person using the Peltier element unit is in a dark, cold indoor environment, the light emitted from the exhaust hole in the second light-emitting mode can inform people around the person that the heat transfer surface is being heated. Therefore, the risk of workers working in dark, cold environments as well as dark, humid environments becoming ill due to differences in the light-emitting mode of the light-emitting unit can be avoided.

[0012] In the above aspect, it is preferable that the Peltier element unit has a ceiling portion that closes the internal space surrounded by the accommodation portion on the side opposite the heat transfer surface, the accommodation portion accommodates a blower that sends air taken in through the air intake hole toward the exhaust hole, the exhaust hole being disposed in the ceiling portion, and the blower device includes a main body portion that accommodates the light-emitting portion, a case portion that has a propeller, and a motor that rotates the propeller.

[0013] According to this aspect, the light emitted by the light-emitting unit can be seen from an exhaust hole provided in the ceiling portion that closes the interior space surrounded by the housing portion having the light-emitting unit on the side opposite the heat transfer surface. This makes it difficult for dust or the like that enters the housing portion through the exhaust hole to come into contact with the light-emitting unit, making it possible to reduce the influence of dust or the like that enters the housing portion of the Peltier element unit on the light-emitting unit. This makes it possible to provide an environment in which people around the person using the Peltier element unit can easily see the light emitted by the light-emitting unit from the ceiling portion.

[0014] In the above aspect, it is preferable that the Peltier element unit accommodates in the accommodation section a blower that blows air taken in through the intake hole toward the exhaust hole, the blower having a main body that accommodates the light-emitting section, a case having a propeller, and a motor that rotates the propeller, and the main body is formed in a manner that allows light emitted by the light-emitting section to pass outside the main body.

[0015] According to this aspect, the light emitted from the light-emitting unit housed in the main body of the air blower passes outside the main body, brightly illuminating the interior of the housing for the Peltier element unit over a wide area. This makes it easier for people around a person using the Peltier element unit to see the light emitted from the light-emitting unit through the exhaust hole, for example, when the person is working in a dark, humid indoor environment. Therefore, the light emitted from the light-emitting unit can further reduce the risk of heatstroke for workers working in a dark, humid indoor environment.

[0016] In the above aspect, it is preferable that the case portion is formed in a shape that allows light emitted by the light emitting portion to pass to the outside of the case portion.

[0017] According to this aspect, the light emitted from the light-emitting unit housed in the case of the blower passes outside the case, illuminating the interior of the housing of the Peltier element unit over a wider area. This makes it easier for people around a person using the Peltier element unit to see the light leaking from the exhaust hole, for example, when the person is working indoors in the dark and in a humid environment. Therefore, the light emitted from the light-emitting unit can further reduce the risk of heatstroke for workers working indoors in the dark and in a humid environment.

[0018] It is preferable that the body temperature adjustment garment be capable of wearing the Peltier element unit of the above aspect.

[0019] The body temperature regulating garments according to the present disclosure are worn directly on the human body or indirectly via underwear etc., and are broadly categorized into (a) outerwear such as jackets, jumpers, suits, vests etc., (b) underwear such as pants, trousers etc., (c) items worn on the feet or legs such as socks, foot warmers etc., and (d) garments worn on the neck, arms etc., and this is a general term that includes each of the concepts (a), (b), (c), and (d).

[0020] According to this aspect, the light emitted by the light-emitting unit can be seen through the exhaust hole of the Peltier element unit in the body temperature regulation garment worn by a person. As a result, even if a worker wearing the body temperature regulation garment is working in a dark, humid indoor environment, for example, people around the worker can see that the heat transfer surface is being cooled by the light emitted by the light-emitting unit, thereby avoiding the risk of heatstroke.

[0021] In the above aspect, the body temperature regulation garment is preferably clothing to which the Peltier element unit can be attached.

[0022] The clothing referred to in this disclosure is broadly divided into (a) outerwear such as jackets, jumpers, suits, vests, etc., (b) underwear such as pants, trousers, etc., and (c) items worn on the feet or legs such as socks, foot warmers, etc., and is a general term that includes each of (a), (b), and (c).

[0023] According to this aspect, people around a person wearing the body temperature regulation garment, which is garment that can be attached to the fabric of the garment, can see the light emitted by the light-emitting unit through the exhaust hole of the Peltier element unit. As a result, even if a worker wearing the body temperature regulation garment is working in the dark in a hot and humid indoor environment, for example, people around the worker can see that the heat transfer surface is being cooled by the light emitted by the light-emitting unit, and the risk of heat stroke can be avoided. [Effects of the Invention]

[0024] Therefore, the Peltier element unit according to the present disclosure has the excellent effect of making it easy to confirm when the heat transfer surface is cooled by heat absorption on one side of the Peltier element, thereby providing a Peltier element unit that avoids the risk of heatstroke for workers working in dark, humid indoor environments.

The Peltier element according to the present disclosure is referred to as a Peltier element PE in this embodiment, and the Peltier element unit according to the present disclosure is referred to as a Peltier element unit 60 in this embodiment.

[0029] As shown in FIGS. 1 to 4, the temperature regulating vest 1 includes a vest body 2, an air blowing unit 40, a Peltier element unit 60, an air blowing operation unit 80, a temperature adjustment operation unit 90, a portable battery 84, and the like. In the first embodiment, for example, there is one air blowing unit 40 and one air blowing operation unit 80. In the first embodiment, for example, there are three Peltier element units 60. In the first embodiment, for example, there is one temperature adjustment operation unit 90.

[0030] <About Best Body 2> First, the vest body 2 will be described with reference to Figures 1 to 4. As shown in Figures 1 and 2, the vest body 2 is formed in the form of a vest (workwear without cuffs) having a front body 4 and a back body 5. However, this temperature regulation vest 1 may also be workwear with long sleeves, short sleeves, or the like.

[0031] The vest body 2 has a fabric 3 formed into a vest shape by an outer fabric 3A and an inner fabric 3B. Both the outer fabric 3A and the inner fabric 3B are made of synthetic resin fibers, such as nylon or polyester, that have excellent heat resistance, strength, and transpiration properties. However, this is not limited to this, and both the outer fabric 3A and the inner fabric 3B may be made of leather. The vest body 2 has a collar 9 at its upper part that forms the neckline where the wearer's neck will be positioned when worn. The vest body 2 has armholes 10 (10A, 10B) on both sides, through which the wearer's arms will be placed when worn. The first armhole 10A is the armhole through which the wearer's left arm will be placed when worn. The second armhole 10B is the armhole through which the wearer's right arm will be placed when worn.

[0032] 1, the outer fabric 3A of the vest body 2 is provided with a first storage section 6 and a second storage section 7, which may be pockets, for example. The first storage section 6 and the second storage section 7 are provided in the internal space formed between the outer fabric 3A and the lining of the front body 4 of the vest body 2. As a result, the air supply wiring 85 connected to the air supply unit 40, the temperature adjustment wiring 95 connected to the Peltier element unit 60, and the portable battery 84 can be taken in and out of the first storage section 6 and the second storage section 7.

[0033] 3 and 4, the lining of the front body 4 of the vest body 2 is provided with storage holes 8, which are openings that allow the air supply wiring 85 and the temperature control wiring 95 to be inserted into the first storage section 6 and the second storage section 7. As a result, even when the air supply wiring 85 and the temperature control wiring 95 are stored in the first storage section 6 with one end on the portable battery 84 side, they can be exposed to the inside of the temperature control vest 1 through the storage holes 8.

[0034] The temperature regulating vest 1 is configured so that when a fastener (not shown) on the front body 4 is opened, the entire lining 11 of the back body 5 of the vest body 2 can be seen from the front body 4 side, as shown in Figures 3 and 4. A single piece of lining 11 is sewn to the back fabric 3B.

[0035] As shown in FIG. 2, the first attachment portion 20 to which the air blowing unit 40 can be attached is disposed near the waist of the back body 5 of the temperature regulating vest 1, and in this embodiment, is provided at one location on the back body 5.

[0036] As shown in FIGS. 2 and 3, the first attachment portion 20 has a first insertion hole 22 formed therein and a first outer peripheral edge portion 21 around the first insertion hole 22. As shown in FIG. 2, the first attachment portion 20 is made of a material (e.g., leather) that is more rigid than the lining 11 and is made of a fabric that does not allow air to pass through. The first attachment portion 20 may also be made of a fabric such as rubber or resin. As a result, a portion of the air blown in by the rotation of the blower fan 42 by the blower unit 40 is directed toward the Peltier element unit 60 attached to the first attachment portion 20. The first attachment portion 20 is sewn onto the back fabric 3B.

[0037] 3, second attachment sections 30 to which Peltier element units 60 can be attached are provided at multiple locations on the lining 11, and in this embodiment, they are provided at three locations on the back body 5. On the back body 5, the second attachment sections 30 are provided at one location on the nape 13, one location near the first armhole 10A, and one location near the second armhole 10B.

[0038] As shown in Fig. 3, the second attachment portion 30 has a first insertion hole 32 formed in the second attachment portion 30 and a second outer peripheral edge portion 31 around the first insertion hole 32. As shown in Figs. 3 and 4, the second attachment portion 30 is made of a material (e.g., leather) that is more rigid than the lining 11 and is made of a fabric that does not allow air to pass through. The second attachment portion 30 may also be made of a fabric such as rubber or resin. The second attachment portion 30 is sewn onto the lining 11.

[0039] <About the blower unit 40> Next, the air blower unit 40 will be described with reference to Figs. 5 to 9. Fig. 5 is a front view showing the main body of the air blower unit shown in Fig. 2, and Fig. 6 is a rear view of the main body of the air blower unit shown in Fig. 2. Fig. 7 is an explanatory diagram showing the air blower unit according to the first embodiment disassembled into a main body and a pressing member. Fig. 8 is an explanatory diagram showing a method for attaching the air blower unit according to the first embodiment to a temperature regulating vest. Fig. 9 is a partial cross-sectional view of the air blower unit attached to the temperature regulating vest according to the first embodiment.

[0040] The air blower unit 40 is attached to the temperature regulating vest 1 and can blow air taken in through the intake hole 46a to the body by the rotation of the air blower fan 42. As shown in FIGS. 5 to 7, the air blower unit 40 of the first embodiment is broadly composed of an air blower fan main body 41 and a pressing member 110. The air blower fan main body 41 includes an air blower fan 42 that blows air, an air blower unit drive part 43 that controls the rotation of the air blower fan 42 with a motor (not shown), and a casing 44 that covers the air blower fan 42 and the air blower unit drive part 43 to allow ventilation. The air blower fan 42 of the first embodiment is, for example, a propeller-type fan having a propeller.

[0041] The air blower unit 40 requires a portable battery 84, which may be a storage battery such as a primary battery or a secondary battery, as a power source for the motor of the air blower unit drive section 43. In the temperature regulating vest 1, the portable battery 84 is stored in the first storage section 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 5200mA.

[0042] As shown in FIGS. 1 to 4, the air blowing unit 40 is electrically connected to a portable battery 84 via an air blowing operation unit 80 by an air blowing wiring 85. When the air blowing unit drive section 43 is electrically connected to the portable battery 84 via the air blowing operation unit 80, the air blowing fan 42 rotates. As a result, the air generated by the rotation of the air blowing fan 42 is blown toward the body surface DS side (body side) of the wearer HM (see FIG. 9).

[0043] 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 blower fan 42 in the radial direction RD on the lower side Lw, which is the side along the axial line AX of the blower fan 42 that blows air when the blower fan 42 rotates. The outer case portion 46 has multiple intake holes 46a for taking in outside air. The inner case portion 45, connected to the blower unit drive portion 43, covers the blower unit drive portion 43 on the Lw side. The inner case portion 45 has multiple discharge holes 45a for sending air from outside the blower unit 40. In the casing 44 according to the first embodiment, the inner case portion 45 is provided in a cylindrical inner case peripheral wall portion 49 that covers the outer peripheral side of the blower fan 42 and the outer peripheral side of a portion of the blower unit drive portion 43 on the Lw side. A male screw 48 is formed on the outer periphery of the inner case peripheral wall portion 49 .

[0044] The outer case portion 46 and the inner case portion 45 are integrally connected via the inner case peripheral wall portion 49. Specifically, the outer case portion 46 is connected to the inner case portion 45 on the upper side Lp of the inner case peripheral wall portion 49. An annular flange 47 that surrounds the outer case portion 46 is formed around the outer case portion 46.

[0045] As shown in Fig. 7, the pressing member 110 according to the first embodiment is a cylindrical, thin-walled member having a pressing portion 111 at the tip on the Lp side that can be positioned opposite the flange 47. A female thread 112 that can be threadedly engaged with the male thread 48 of the inner case peripheral wall portion 49 is formed on the inner periphery of the pressing member 110. Non-slip protrusions are intermittently provided on the outer periphery of the pressing member 110. When the male thread 48 of the inner case peripheral wall portion 49 of the blower fan main body 41 is threadedly engaged with the female thread 112 of the pressing member 110 by the protrusions, the pressing member 110 is firmly gripped by the protrusions, making it easy to rotate.

[0046] <Installing the blower unit 40> 8, when attaching the air blower unit 40 according to the first embodiment, first, the lower side Lw of the air blower fan body 41 is inserted into the first insertion hole 22 formed in the first attachment part 20 and the fabric insertion hole 3C of the back fabric 3B from the outside 20a of the first attachment part 20. With the flange 47 abutting the first outer peripheral edge 21 of the first attachment part 20, the outer case part 46 is placed in the first insertion hole 22 and the fabric insertion hole 3C of the back fabric 3B. Next, a person places the pressing member 110 near the first outer peripheral edge 21 from the lining 11 side of the temperature regulating vest 1, and rotates the air blower fan body 41 and the pressing member 110 relative to each other to assemble them. Then, a person fastens the male screw 48 of the blower fan main body 41 to the female screw 112 of the pressing member 110 by screwing them together, thereby sandwiching the first outer peripheral edge 21 and the back fabric 3B between the flange 47 and the pressing member 111. The blower fan main body 41 and the pressing member 110 are fixed to the fabric 3 with the first outer peripheral edge 21 and the back fabric 3B sandwiched between the flange 47 and the pressing member 111. In this way, the blower unit 40 is fixed to the fabric 3, as shown in Figures 2, 4, and 9.

[0047] Portable battery 84 and airflow wiring 85 are freely detachable by connection via a connector such as a USB (Universal Serial Bus) connection. Power from portable battery 84 is supplied to airflow unit drive section 43 and the motor of airflow unit drive section 43 through airflow wiring 85.

[0048] When a voltage of 5V is supplied through airflow wiring 85, airflow control section 81 controls airflow unit drive section 43 to drive propeller-type airflow fan 42, causing propeller-type airflow fan 42 to rotate. As propeller-type airflow fan 42 rotates, air from outside temperature regulating vest 1 is taken in from the back of airflow unit 40 body shown in Fig. 6, and the air is then blown out from the front of airflow unit 40 body shown in Fig. 5. As shown in Figs. 1 to 4, airflow unit 40 is electrically connected to portable battery 84 via airflow operation unit 80 by airflow wiring 85.

[0049] <About the Peltier element unit 60> Next, the Peltier element unit 60 will be described with reference to Figs. 10 to 12. Fig. 10 is an explanatory diagram showing the Peltier element unit from the ceiling side of a temperature regulation vest. Fig. 11 is an explanatory diagram showing the Peltier element unit from the heat transfer surface side of a temperature regulation vest. Fig. 12 is an exploded perspective view showing the configuration of the Peltier element unit.

[0050] As shown in FIGS. 10 to 12, the Peltier element unit 60 has a Peltier element PE (an example of a Peltier element according to the present disclosure) built into its main body. The Peltier element PE is a type of plate-shaped semiconductor thermoelectric element. When a direct current is supplied to the Peltier element PE, one surface PEA of the flat plate portion of the Peltier element PE absorbs heat to, for example, about 10°C due to the Peltier effect, and enters an endothermic state (cooled surface). At the same time, the other surface PEB on the opposite side generates heat to, for example, about 30°C, and enters a heat-generating state (heated surface). The Peltier element is an element that transfers heat from the cooled surface to the heated surface, generating a large amount of heat on the heated surface side.

[0051] In this embodiment, the Peltier element PE has the property of absorbing heat and generating heat simultaneously within a temperature range of, for example, about 20 to 30° C. relative to the outside air temperature.

[0052] For example, when a Peltier element PE is operating in summer at an outside temperature of 35°C, the cooling surface generates heat of 15-15°C, which is used to cool the body. At the same time, the heating surface generates heat of 55-65°C, which is used as exhaust heat.

[0053] On the other hand, when the Peltier element PE is operating in winter at an outside temperature of 5°C, the cooling surface generates heat of -15 to -25°C, which is used as waste heat. At the same time, the heating surface generates heat of 25 to 35°C, which is used as warmth to warm the body.

[0054] As shown in FIGS. 10 to 12, the Peltier element unit 60 has a heat transfer surface 61 (cooling surface 61A or heating surface 61B) which is one surface thereof, a circular ceiling portion 71, a cylindrical portion 64, and a housing portion 62 that houses the Peltier element PE. The Peltier element unit 60 also has a heat exchange surface 73 on the opposite side of the heat transfer surface 61. For example, the heat transfer surface 61 corresponds to the heat transfer surface in the present disclosure. For example, the ceiling portion 71 corresponds to the ceiling portion in the present disclosure. For example, the housing portion 62 corresponds to the housing portion in the present disclosure. For example, the heat exchange surface 73 corresponds to the heat exchange surface in the present disclosure.

[0055] 11, the cylindrical portion 64 has a plurality of (e.g., four) intake portions 65 formed at intervals in the circumferential direction. Each of the plurality of (e.g., four) intake portions 65 has a plurality of (e.g., eight) intake holes 65a formed at intervals in the circumferential direction. The plurality of (e.g., eight) intake holes 65a are holes formed to take in air from outside the housing portion 62 of the Peltier element unit 60 into the housing portion 62 of the Peltier element unit 60. For example, the intake holes 65a correspond to the intake holes of the present disclosure.

[0056] As shown in FIGS. 10 and 12, the ceiling portion 71 closes the internal space IS (see FIG. 21) surrounded by the storage portion 62 on the side opposite the heat transfer surface 61. As shown in FIG. 9, the ceiling portion 71 is formed with a plurality of exhaust holes 72 for discharging air that has undergone heat exchange by the heat exchange surface 73 to the outside of the Peltier element unit 60. The plurality of exhaust holes 72 are holes formed for discharging air taken in from a plurality of (e.g., eight) intake holes 65a to the outside of the storage portion 62. For example, the exhaust holes 72 correspond to the exhaust holes in the present disclosure. For example, the internal space IS corresponds to the internal space in the present disclosure.

[0057] As shown in Fig. 12, the Peltier element unit 60 also has a heat exchange surface 73 that exchanges heat by absorbing heat from the Peltier element PE and dissipating it into the air, and an annular inner flange 63 formed on the cover member of the main body. Furthermore, as shown in Fig. 12, the Peltier element unit 60 also has a blower 100 that blows air taken in through the intake holes 65a toward the exhaust holes 72, and a ring fastener 120. The blower 100 blows the air that has undergone heat exchange on the heat exchange surface 73 out of the Peltier element unit 60 through the multiple exhaust holes 72. The Peltier element unit 60 of this embodiment may have, for example, a substantially polygonal inner flange 63 formed on the cover member of the housing portion 62. For example, the blower 100 corresponds to the blower of the present disclosure.

[0058] As shown in FIG. 12, a guide rail 66 is provided on the outer peripheral surface of the housing portion 62 of the Peltier element unit 60. As shown in FIG. 12, the guide rail 66 extends toward the inner flange 63 and in an arc shape between one end 66a and the other end 66b along the circumferential direction CR of the main body portion. A plurality of guide rails 66 (e.g., four) are provided at different positions in the circumferential direction CR of the main body portion. As shown in FIG. 12, mounting grooves 69 are provided between each of the plurality of guide rails 66 and the inner flange 63. The plurality of mounting grooves 69 (e.g., four) are provided along the circumferential direction CR of the main body portion. Adjacent guide rails 66 in the circumferential direction CR are disposed at the same height in the axial direction L (see FIGS. 12, 16, 18 to 20). As shown in FIG. 12, gaps 70 are provided between adjacent guide rails 66 of the four guide rails 66. The outer circumferential surface of the main body is provided with a plurality of (for example, four) gaps 70. As shown in FIG.

[0059] As shown in Fig. 12, the ring fastener 120 is formed so as to be freely fastened to and released from the accommodation portion 62, which is the end portion opposite the heat transfer surface 61 (cooling surface 61A or 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 twelve elliptical holes formed therein. The inner diameter of the ring fastener 120 is larger than the outer diameter of the ceiling portion 71 and smaller than the outer diameter of the inner flange 63.

[0060] Protrusions 122 connectable to the guide rails 66 are provided on the inner peripheral surface of the ring fastener 120. A plurality of (e.g., four) protrusions 122 are provided at intervals in the circumferential direction CR of the ring fastener 120. Each of the protrusions 122 is engageable with a corresponding one of the restricting portions 67 of the guide rails 66. Adjacent protrusions 122 in the circumferential direction CR are disposed at the same height in the axial direction L. The protrusions 122 are inclined toward the surface with respect to a plane perpendicular to the surface of the outer flange 12, with an inclination angle θ2 of 3°. This allows each of the protrusions 122 to be easily connected to a corresponding one of the guide rails 66. In the temperature regulating vest 1, three Peltier element units 60 (first Peltier element unit 60A, second Peltier element unit 60B, and third Peltier element unit 60C) are attached to three second mounting portions 30 on the vest body 2.

[0061] The heat transfer surface 61 is exposed to the outside, and the heat transfer surface 61 and the ceiling portion 71 are arranged on opposite sides of each other in the Peltier element unit 60. The heat transfer surface 61 is made of, for example, stainless steel or a metal with excellent thermal conductivity.

[0062] The heat exchange surface 73 formed on the back side of the heat transfer surface 61 is made of a metal with excellent thermal conductivity, such as aluminum or copper. The heat exchange surface 73 has a plurality of (e.g., 117) heat dissipation fins 73a configured in a protruding shape. Because the heat dissipation fins 73a are configured in a protruding shape, the surface area of the heat dissipation fins 73a is increased, thereby expanding the area that comes into contact with the air, allowing for efficient dissipation of heat from the Peltier element. On the heat exchange surface 73, the heat dissipation fins 73a are aligned at regular intervals so that air flowing in from the air intake holes 65a can pass between the heat dissipation fins 73a. As a result, for example, cooling air flowing in between the heat dissipation fins 73a comes into contact with the heat dissipation fins 73a, allowing efficient exchange of heat from the Peltier element PE.

[0063] 12, a heat transfer surface 61 (cooling surface 61A or heating surface 61B) is provided at the end opposite to the main body portion in the axial direction L along the axial line AX of the accommodation portion 62. The main body portion is formed in a cylindrical shape and is provided with an inner flange 63 that protrudes in the shape of an annular plate from the outer peripheral end portion.

[0064] As shown in Fig. 12, blower device 100 according to this embodiment includes main body 101 that houses control board 105 (described later), and case 102 that has propeller 103 (described later) and covers drive motor 104 (described later). As shown in Fig. 12, an adhesive protective part 74 is attached to surface 100A of blower device 100 according to this embodiment to prevent dust and the like from coming into contact with control board 105. Adhesive protective part 74 is formed of a thin vinyl member. For example, main body 101 corresponds to the main body of the present disclosure.

[0065] 1, 2, and 4, in the Peltier element unit 60, the Peltier element PE is electrically connected to the portable battery 84 via the temperature adjustment operation unit 90 by a temperature adjustment wiring 95. The portable battery 84 and the temperature adjustment wiring 95 are freely detachable by connection via a connector such as a USB (Universal Serial Bus) connection.

[0066] For example, when three Peltier element units 60 are attached to the temperature regulating vest 1, the temperature regulating wiring 95 takes the form of three temperature regulating branch lines 95A, 95B, and 95C that extend from a single temperature regulating main line 94 and are divided at a temperature regulating branch section 96. In other words, the number of temperature regulating branch lines 95A, 95B, 95C, etc. matches the number of Peltier element units 60.

[0067] The temperature adjustment main line 94 of the temperature adjustment wiring 95 is connected to the portable battery 84. For example, the temperature adjustment branch line 95A is connected to the first Peltier element unit 60A. For example, the temperature adjustment branch line 95B is connected to the second Peltier element unit 60B. For example, the temperature adjustment branch line 95C is connected to the third Peltier element unit 60C. However, this is not limited to this. The temperature adjustment branch lines 95A, 95B, 95C may be connected arbitrarily at the discretion of the wearer HM, particularly by simplifying the wiring route, as long as there is a one-to-one connection relationship with the three Peltier element units 60 (first to third Peltier element units 60A, 60B, 60C).

[0068] <About the blower device 100> Next, the air blower 100 will be described with reference to Figs. 13 to 15. Fig. 13 is an explanatory diagram showing the air blower from the front side. Fig. 14 is an explanatory diagram showing the air blower from the back side. Fig. 15 is an exploded perspective view showing the configuration of the air blower.

[0069] In the blower 100 of this embodiment, air is taken in through a plurality of (e.g., eight) air intake holes 65a by the rotation of the propeller 103, and the air that has undergone heat exchange on the heat exchange surface 73 can be discharged through a plurality of exhaust holes 72. As shown in FIGS. 13 to 15, the blower 100 includes a main body 101, a case 102 having the propeller 103, a drive motor 104 that rotates the propeller 103, and a plurality of (e.g., four) bases 109. Furthermore, as shown in FIGS. 13 to 15, the blower 100 includes a control board 105 that outputs signals output from the temperature adjustment control unit 91 to the drive motor 104, the first light-emitting unit 106, the second light-emitting unit 107, etc. The control board 105 is housed in the main body 101. The blower 100 is, for example, a propeller-type blower having the propeller 103. For example, the first light-emitting unit 106 and the second light-emitting unit 107 correspond to the light-emitting units of the present disclosure. For example, the main body unit 101 corresponds to the main body unit of the present disclosure. For example, the propeller 103 corresponds to the propeller of the present disclosure. For example, the case unit 102 corresponds to the case unit of the present disclosure. For example, the drive motor 104 corresponds to the motor of the present disclosure.

[0070] A first light-emitting unit 106 capable of emitting blue light and a second light-emitting unit 107 capable of emitting red light are disposed on a control board 105. For example, bare chip or bullet-type LEDs (Light Emitting Diodes) are preferably used as the light-emitting elements constituting the first light-emitting unit 106 and the second light-emitting unit 107. As shown in FIGS. 13 and 15 , the first light-emitting unit 106 and the second light-emitting unit 107 are arranged in parallel on the control board 105. For example, the first light-emitting unit 106 emitting blue light corresponds to a first light-emitting mode of the present disclosure. For example, the second light-emitting unit 107 emitting red light corresponds to a second light-emitting mode of the present disclosure.

[0071] 15, the main body 101 is formed in a manner that allows the light emitted by the first light-emitting unit 106 and the light emitted by the second light-emitting unit 107 to pass to the outside of the main body 101. Specifically, the main body 101 is formed of a translucent material that scatters the light emitted by the first light-emitting unit 106 and the light emitted by the second light-emitting unit 107 as they pass through the main body 101 and diffuses it to the outside of the main body 101. This allows the blue light emitted by the first light-emitting unit 106 and the red light emitted by the second light-emitting unit 107 to brightly illuminate a wide area inside the internal space IS (see FIG. 21) of the accommodating unit 62, making the light emitted from the multiple exhaust holes 72 easy to see.

[0072] 15, the case 102 is formed in a manner that allows the light emitted from the first light-emitting unit 106 and the light emitted from the second light-emitting unit 107 to pass to the outside of the case 102. Specifically, the case 102 is formed of a translucent material that scatters the light emitted from the first light-emitting unit 106 and the light emitted from the second light-emitting unit 107 as they pass through the case 102 and diffuses it to the outside of the case 102. This allows the blue light emitted from the first light-emitting unit 106 and the red light emitted from the second light-emitting unit 107 to brightly illuminate a wide area inside the internal space IS (see FIG. 21) of the housing unit 62, making it easier to see the light emitted from the multiple exhaust holes 72.

[0073] As shown in FIG. 13 , the front surface 100A of the blower 100 has a first opening 100C having a substantially rectangular shape and a second opening 100D having a substantially oval shape. The first opening 100C formed on the front surface 100A of the blower 100 allows the control board 105 housed in the blower 100 to be viewed from the front surface 100A. The second opening 100D formed on the front surface 100A of the blower 100 allows the control board 105, first light-emitting unit 106, and second light-emitting unit 107 housed in the blower 100 to be viewed from the front surface 100A. By attaching the adhesive protective unit 74 to the front surface 100A of the main body 101 according to this embodiment, the first opening 100C and the second opening 100D can be blocked, preventing dust and other particles from contacting the control board 105. The blower 100 requires a portable battery 84, which is a storage battery such as a primary battery or a secondary battery, as a power source for the drive motor 104.

[0074] The blower device 100 is electrically connected to the portable battery 84 via the temperature adjustment operation unit 90 by the temperature adjustment wiring 95. When the blower device 100 is electrically connected to the portable battery 84 via the temperature adjustment operation unit 90, the propeller 103 is rotated by the drive of the drive motor 104. As a result, the wind generated by the rotation of the propeller 103 is sent toward the plurality of exhaust holes 72.

[0075] 13 and 15, through holes 108 are formed at the upper left end, upper right end, lower left end, and lower right end of the fan device 100, penetrating from the front surface 100A to the back surface 100B of the fan device 100. By attaching a base portion 109 to each of the four through holes 108, the main body portion 101 and the case portion 102 of the fan device 100 housed in the housing portion 62 are prevented from contacting the heat exchange surface 73. The base portion 109 is inserted into the through holes 108 from the back surface 100B side of the fan device 100 and is fitted to the main body portion 101.

[0076] <Installing the Peltier element unit 60> The attachment of the Peltier element unit 60 will be described using Figures 16 and 17. Figure 16 is an explanatory diagram showing a method for attaching the Peltier element unit to a temperature regulating vest. Figure 17 is a development view in which the outer circumferential surface of the housing part is developed on a plane.

[0077] A method of attaching the Peltier element unit 60 to the second attachment portion 30 will be described using Figure 16. As shown in Figure 16, when attaching the Peltier element unit 60, the exhaust hole 72 side of the ceiling portion 71 of the Peltier element unit 60 is inserted into the first insertion hole 32 formed in the second attachment portion 30 and the fabric insertion hole 3C of the back fabric 3B from the inside 30a of the second attachment portion 30. The Peltier element unit 60 is placed in the first insertion hole 32 and the fabric insertion hole 3C of the back fabric 3B with the inner flange 63 abutting against the second outer peripheral edge portion 31. The first insertion hole 32 is a hole for attaching the Peltier element unit 60 so that the heat transfer surface 61 (cooling surface 61A or heating surface 61B) of the Peltier element unit 60 is in close contact with the body of the wearer HM of the temperature regulating vest 1.

[0078] Next, the outer flange 121 is brought into contact with the inner fabric 3B from the outside of the inner fabric 3B. The person inserts the receiving portion 62 into the inside of the ring fastener 120, and inserts each of the multiple protrusions 122 of the ring fastener 120 into each of the multiple gaps 70. As a result, the inner fabric 3B and the second outer peripheral edge portion 31 are sandwiched between the inner flange 63 of the receiving portion 62 and the outer flange 121 of the ring fastener 120. Next, the person rotates the receiving portion 62 and the ring fastener 120 relatively in the circumferential direction CR of the receiving portion 62, thereby inserting each of the protrusions 122 into the mounting groove portion 69 from one end 66a of the guide rail 66. Furthermore, the person rotates the storage portion 62 and the ring fastener 120 relative to each other in the circumferential direction CR of the storage portion 62, causing each protrusion 122 to slide on each guide rail 66 along the circumferential direction CR of the storage portion 62. Next, the person rotates the storage portion 62 and the ring fastener 120 relative to each other in the circumferential direction CR of the storage portion 62, causing the multiple protrusions 122 to climb over the multiple restricting portions 67 respectively. When each of the multiple protrusions 122 climbs over each of the multiple restricting portions 67, the multiple restricting portions 67 restrict the multiple protrusions 122 from moving in the counter-circumferential direction ACR of the storage portion 62. The protrusions 122 that have climbed over the restricting portions 67 and stopped moving engage with the restricting portions 67 in surface contact, thereby fixing the back fabric 3B and the second outer peripheral edge portion 31. As a result, the back fabric 3B and the second outer peripheral edge portion 31 are fixed in a sandwiched state between the inner flange 63 and the outer flange 121. The protrusion 122 of the ring fastener 120 and the restricting portion 67 of the guide rail 66 are fixed by engagement, not by screwing.

[0079] The first Peltier element unit 60A is attached to the second attachment portion 30 of the neck portion 13. In this case, the heat transfer surface 61 (cooling surface 61A or heating surface 61B) faces and is in contact with the body side (nape of the neck) of the wearer HM of the temperature regulating vest 1 (see FIG. 26). This allows the heat transfer surface 61 (cooling surface 61A or heating surface 61B) to come into contact with the body surface DS of the wearer HM himself / herself, either directly or indirectly via underwear or the like, thereby cooling the nape of the wearer's neck.

[0080] The Peltier element units 60 (second Peltier element unit 60B, third Peltier element unit 60C) are attached to the second attachment parts 30 near the armholes 10 (first armholes 10A, second armholes 10B). In this case, the heat transfer surface 61 (cooling surface 61A or heating surface 61B) faces and is in contact with the body side (near the armpits) of the wearer HM of the temperature regulating vest 1 (see FIG. 26). This allows the heat transfer surface 61 (cooling surface 61A or heating surface 61B) to come into contact with the body surface DS of the wearer HM directly or indirectly via underwear or the like, thereby cooling the armpits.

[0081] Next, referring to FIG. 17, the multiple guide rails 66 provided on the outer peripheral surface of the accommodation portion 62 unfolded on a plane will be described. As shown in FIG. 17, the multiple guide rails 66 connect one end 66a to the other end 66b of each guide rail 66 and have a sliding surface 68 that contacts each protrusion 122 of the ring fastener 120. As shown in FIG. 17, multiple (e.g., four) restricting portions 67 are arranged on each sliding surface 68 of the multiple guide rails 66. Each of the multiple restricting portions 67 restricts the movement of the multiple protrusions 122 that move along the sliding surface 68 toward the counter-circumferential direction ACR of the main body portion. The restricting portions 67 are intermittently arranged on the sliding surface 68 connecting one end 66a to the other end 66b of each guide rail 66 in the order of a first restricting portion 67a, a second restricting portion 67b, a third restricting portion 67c, and a fourth restricting portion 67d.

[0082] As shown in Fig. 17, the multiple guide rails 66 are inclined toward the cylindrical portion 64 with respect to a plane perpendicular to the axial line AX of the accommodating portion 62. All of the multiple guide rails 66 in the first embodiment have an inclination angle θ1, as an example, of 3° between one end 66a and the other end 66b. As a result, all of the multiple guide rails 66 in the first embodiment are formed in an inclined state with a height difference ΔH in the axial direction L between one end 66a and the other end 66b. In other words, the inclination angle θ1 of the sliding surface 68 according to the first embodiment is 3° toward the cylindrical portion 64 with respect to a plane perpendicular to the axial line AX of the accommodating portion 62.

[0083] <About the thickness of the material sandwiched between the inner flange 63 and the outer flange 121> 18 to 20, the locations where the protrusions 122 are engaged and fixed depending on the thickness of the fabric sandwiched between the inner flange 63 and the outer flange 121 will be described. FIG. 18 is a side view of the Peltier element unit, and is an explanatory diagram showing the inner flange and the outer flange engaged at the first stage. FIG. 19 is a side view of the Peltier element unit, and is an explanatory diagram showing the inner flange and the outer flange engaged at the second stage. FIG. 20 is a side view of the Peltier element unit, and is an explanatory diagram showing the inner flange and the outer flange engaged at the third stage.

[0084] 18, a case will be described in which each of the multiple protrusions 122 climbs over the first restricting portion 67a of the respective guide rails 66 and the guide rails 66 engage with the protrusions 122 in the first stage. When the thickness of the fabric of the temperature regulating vest 1 is X1 (for example, approximately 3 mm), a person inserts the housing portion 62 into the inside of the ring fastener 120 with the fabric sandwiched between the inner flange 63 and the outer flange 121. As a result, each of the multiple protrusions 122 enters each of the multiple gaps 70. Next, when a person rotates the housing portion 62 and the ring fastener 120 relatively in the circumferential direction CR of the housing portion 62, each of the protrusions 122 of the ring fastener 120 enters the mounting groove portion 69 from one end 66a of the guide rail 66. Furthermore, when a person rotates the storage portion 62 and the ring fastener 120 relative to each other in the circumferential direction CR of the storage portion 62, each of the multiple protrusions 122 slides on the respective guide rails 66 along the circumferential direction CR of the storage portion 62. When the storage portion 62 and the ring fastener 120 are rotated relative to each other by, for example, 15 degrees along the circumferential direction CR of the storage portion 62, each of the multiple protrusions 122 climbs over each of the multiple first restriction portions 67a disposed thereon. The movement of each of the protrusions 122 in the anti-circumferential direction ACR is restricted by each of the first restriction portions 67a that have climbed over. In order for each of the multiple protrusions 122 to climb over each of the multiple first restriction portions 67a, the angle by which the storage portion 62 and the ring fastener 120 rotate relative to each other in the circumferential direction CR of the storage portion 62 is not limited to 15 degrees. For example, it is preferably any angle between 15 degrees and 20 degrees.

[0085] 18, each of the multiple protrusions 122, whose movement in the circumferential direction CR of the storage section 62 has stopped in the first stage, comes into surface contact with and engages with each of the multiple first restricting portions 67a, thereby being fixed. In this case, the Peltier element unit 60 can be attached to the temperature adjustment vest 1 with the fabric of the temperature adjustment vest 1 having a thickness of X1 (for example, approximately 3 mm) sandwiched between the inner flange 63 and the outer flange 121. To release the Peltier element unit 60, a person rotates the storage section 62 and the ring fastener 120 relatively in the counter-circumferential direction ACR of the storage section 62 by, for example, 15 degrees, causing each of the multiple protrusions 122 to climb over a corresponding one of the first restricting portions 67a. This allows the Peltier element unit 60 to be released from the temperature adjustment vest 1.

[0086] Next, using Figure 19, a case will be described in which each of the multiple protrusions 122 climbs over the second restriction portion 67b of the respective guide rails 66 and the guide rails 66 engage with the protrusions 122 in the second stage. When the thickness of the fabric of the temperature regulating vest 1 is X2 (for example, approximately 2 mm), a person inserts the housing portion 62 into the inside of the ring fastener 120 with the fabric sandwiched between the inner flange 63 and the outer flange 121. As a result, each of the protrusions 122 enters each of the gaps 70. Next, when a person rotates the housing portion 62 and the ring fastener 120 relatively in the circumferential direction CR of the housing portion 62, each of the protrusions 122 of the ring fastener 120 enters the mounting groove portion 69 from one end 66a of the guide rail 66. Furthermore, when a person rotates the storage portion 62 and the ring fastener 120 relatively in the circumferential direction CR of the storage portion 62, each of the multiple protrusions 122 slides on the respective guide rails 66 along the circumferential direction CR of the storage portion 62. When the storage portion 62 and the ring fastener 120 are rotated relatively by, for example, 15 degrees along the circumferential direction CR of the storage portion 62, each of the multiple protrusions 122 climbs over each of the multiple first restriction portions 67a arranged thereon. The movement of each protrusion 122 in the anti-circumferential direction ACR is restricted by each of the first restriction portions 67a that it has climbed over.

[0087] Furthermore, when a person rotates the storage portion 62 and the ring fastener 120 relatively along the circumferential direction CR of the storage portion 62, for example, by 15 degrees, each of the multiple protrusions 122 slides over and climbs over each of the multiple second restriction portions 67b. The movement of each of the protrusions 122 in the anti-circumferential direction ACR is restricted by each of the multiple second restriction portions 67b that it has climbed over. In order for each of the multiple protrusions 122 to climb over each of the multiple second restriction portions 67b, the angle by which the storage portion 62 and the ring fastener 120 are rotated relatively along the circumferential direction CR of the storage portion 62 is not limited to 15 degrees. For example, it is preferably anywhere between 15 degrees and 20 degrees.

[0088] As shown in FIG. 19 , the multiple protrusions 122, whose movement in the circumferential direction CR of the storage section 62 has stopped in the second stage, come into surface contact with and engage with the multiple second restricting portions 67b, thereby being fixed. In this case, the Peltier element unit 60 can be attached to the temperature adjustment vest 1 with the fabric of the temperature adjustment vest 1 having a thickness of X2 (for example, approximately 2 mm) sandwiched between the inner flange 63 and the outer flange 121. To release the Peltier element unit 60, a person rotates the storage section 62 and the ring fastener 120 relatively in the counter-circumferential direction ACR of the storage section 62 by, for example, 30 degrees, causing each of the multiple protrusions 122 to climb over the first restricting portions 67a and the second restricting portions 67b. This allows the Peltier element unit 60 to be released from the temperature adjustment vest 1.

[0089] Next, using Figure 20, a case will be described in which each of the multiple protrusions 122 climbs over the third restriction portion 67c of the respective guide rails 66 and the guide rails 66 engage with the protrusions 122 in the third stage. When the thickness of the fabric of the temperature regulating vest 1 is X3 (for example, approximately 1 mm), a person inserts the housing portion 62 into the inside of the ring fastener 120 with the fabric sandwiched between the inner flange 63 and the outer flange 121. As a result, each of the protrusions 122 enters each of the gaps 70. Next, when a person rotates the housing portion 62 and the ring fastener 120 relatively in the circumferential direction CR of the housing portion 62, each of the protrusions 122 of the ring fastener 120 enters the mounting groove portion 69 from one end 66a of the guide rail 66. Furthermore, when a person rotates the storage portion 62 and the ring fastener 120 relatively in the circumferential direction CR of the storage portion 62, each of the multiple protrusions 122 slides on the respective guide rails 66 along the circumferential direction CR of the storage portion 62. When the storage portion 62 and the ring fastener 120 are rotated relatively by, for example, 15 degrees along the circumferential direction CR of the storage portion 62, each of the multiple protrusions 122 climbs over each of the multiple first restriction portions 67a arranged thereon. The movement of each protrusion 122 in the anti-circumferential direction ACR is restricted by each of the first restriction portions 67a that it has climbed over.

[0090] Furthermore, when a person relatively rotates the accommodation portion 62 and the ring fastener 120 along the circumferential direction CR of the accommodation portion 62, for example, by 15 degrees, each of the multiple protrusions 122 slides over and climbs over each of the multiple second restriction portions 67b. The movement of each of the protrusions 122 in the anti-circumferential direction ACR is restricted by each of the second restriction portions 67b that it has climbed over.

[0091] Furthermore, when a person rotates the storage portion 62 and the ring fastener 120 relatively along the circumferential direction CR of the storage portion 62, for example, by 15 degrees, each of the multiple protrusions 122 slides over and climbs over each of the multiple third restriction portions 67c. The movement of each of the protrusions 122 in the anti-circumferential direction ACR is restricted by each of the multiple third restriction portions 67c that it has climbed over. In order for each of the multiple protrusions 122 to climb over each of the multiple third restriction portions 67c, the angle by which the storage portion 62 and the ring fastener 120 are rotated relatively along the circumferential direction CR of the storage portion 62 is not limited to 15 degrees. For example, it is preferably anywhere between 15 degrees and 20 degrees.

[0092] As shown in FIG. 20 , the plurality of protrusions 122, whose movement in the circumferential direction CR of the storage section 62 has stopped in the third stage, come into surface contact with and engage with the plurality of third restricting portions 67c, thereby being fixed. In this case, the Peltier element unit 60 can be attached to the temperature regulation vest 1 with the fabric of the temperature regulation vest 1 having a thickness of X3 (for example, approximately 1 mm) sandwiched between the inner flange 63 and the outer flange 121. To release the Peltier element unit 60, a person rotates the storage section 62 and the ring fastener 120 relatively in the counter-circumferential direction ACR of the storage section 62, for example, by 45 degrees, causing each of the plurality of protrusions 122 to climb over each of the first restricting portions 67a to the third restricting portions 67c. This allows the Peltier element unit 60 to be released from the temperature regulation vest 1.

[0093] When each of the multiple protrusions 122 climbs over the third restricting portion 67c, each of the multiple protrusions 122 cannot climb over each of the multiple fourth restricting portions 67d even if a person rotates the accommodation portion 62 and the ring fastener 120 relatively in the circumferential direction CR of the accommodation portion 62. This makes it possible to prevent the Peltier element unit 60 from falling off from the temperature regulating vest 1 due to the relative rotation of the accommodation portion 62 and the ring fastener 120 in the circumferential direction of the accommodation portion 62.

[0094] When attaching the Peltier element unit 60 according to the first embodiment to the vest body 2, a person can attach the Peltier element unit 60 to the temperature regulating vest 1 with a single touch. Furthermore, by rotating the housing portion 62 and the ring fastener 120 relative to each other, the positions at which the Peltier element unit 60 engages with each of the multiple protrusions 122 can be changed in stages. As a result, if the fabric thickness of the temperature regulating vest 1 is approximately 3 mm, each of the multiple protrusions 122 will engage with each of the multiple first restricting portions 67a, allowing the Peltier element unit 60 to be attached to the temperature regulating vest 1. If the fabric thickness of the temperature regulating vest 1 is approximately 2 mm, each of the multiple protrusions 122 will engage with each of the second restricting portions 67b, allowing the Peltier element unit 60 to be attached to the temperature regulating vest 1. If the fabric thickness of the temperature regulating vest 1 is approximately 1 mm, each of the multiple protrusions 122 will engage with each of the third restricting portions 67c, allowing the Peltier element unit 60 to be attached to the temperature regulating vest 1. Therefore, regardless of the thickness of the fabric of the temperature regulating vest 1, a person can attach the Peltier element unit 60 to the temperature regulating vest 1 in accordance with that thickness. Therefore, it is easy to attach the Peltier element unit 60 according to the first embodiment to the fabric of the temperature regulating vest 1, improving the ease of use of the temperature regulating vest 1. Furthermore, even if the lining fabric 3B and the second attachment part 30 are repeatedly clamped between the inner flange 63 and the ring fastener 120, plastic deformation of the lining fabric 3B and the second attachment part 30 is unlikely. Therefore, even when the Peltier element unit 60 is attached to the temperature regulating vest 1, rattle and damage to the lining fabric 3B and the second attachment part 30 can be prevented.

[0095] <Regarding the flange inclination angle> The inclination angles of the inner flange 63 and the outer flange 121 will be described with reference to Figure 21. Figure 21 is a partial cross-sectional view of the Peltier element unit attached to the first attachment portion.

[0096] 21 , the surface of the inner flange 63 and the surface of the outer flange 121 of the Peltier element unit 60 are in contact, i.e., face-to-face contact, with the second mounting portion 30. The face-to-face contact between the surface of the inner flange 63 and the surface of the outer flange 121 can prevent the Peltier element unit 60 from coming off the second mounting portion 30.

[0097] As shown in FIG. 21, the back surface of the inner flange 63 and the back surface of the outer flange 121 are not in contact with the second attachment portion 30.

[0098] In this embodiment, the front and back surfaces of the inner flange 63 are inclined with respect to a plane perpendicular to the heat transfer surface 61 (cooling surface 61A or heating surface 61B) toward the ceiling portion 71 where the exhaust holes 72 are formed. The inclination angle θ3 of the inner flange 63 is 20°.

[0099] 21, the front and back surfaces of the outer flange 121 are inclined toward the ceiling 71 with respect to a plane perpendicular to the heat transfer surface 61 (cooling surface 61A or heating surface 61B), similar to the inner flange 63. In this embodiment, the inclination angle θ4 of the outer flange 121 is 20°.

[0100] When the first light-emitting element 106 emits blue light, the internal space IS of the storage unit 62 is brightly illuminated in blue. When the second light-emitting element 107 emits red light, the internal space IS of the storage unit 62 is brightly illuminated in red.

[0101] <Regarding the First Light-Emitting Unit 106 and the Second Light-Emitting Unit 107> The first light-emitting unit 106 and the second light-emitting unit 107 will be described with reference to Fig. 22 and Fig. 23. Fig. 22 is an explanatory diagram showing a state in which the first light-emitting unit in the Peltier element unit is lit in blue. Fig. 23 is an explanatory diagram showing a state in which the second light-emitting unit in the Peltier element unit is lit in red.

[0102] When the heat transfer surface 61 is cooled due to heat absorption by one surface PEA of the Peltier element PE, if the first temperature adjustment operation unit 92A is pressed twice in succession, the first light-emitting unit 106 disposed on the control board 105 lights up in blue, as shown in Fig. 22. Even if the first temperature adjustment operation unit 92A is pressed twice in succession when the heat transfer surface 61 is cooled due to heat absorption by one surface PEA of the Peltier element PE, the second light-emitting unit 107 disposed on the control board 105 remains off, as shown in Fig. 22.

[0103] When the heat transfer surface 61 is heated due to heat generation on one surface PEA of the Peltier element PE, and the second temperature adjustment operation unit 92B is pressed twice in succession, the second light-emitting unit 107 disposed on the control board 105 lights up in red, as shown in Fig. 23. Even if the second temperature adjustment operation unit 92B is pressed twice in succession when the heat transfer surface 61 is heated due to heat generation on one surface PEA of the Peltier element PE, the first light-emitting unit 106 disposed on the control board 105 remains off, as shown in Fig. 23.

[0104] <Regarding the first operation unit light-emitting unit 130 and the second operation unit light-emitting unit 131> The first operation part light emitting part 130 and the second operation part light emitting part 131 will be described using Figures 24 and 25. Figure 24 is an explanatory diagram showing a state in which the first operation part light emitting part in the temperature adjustment operation unit is lit in blue. Figure 25 is an explanatory diagram showing a state in which the second operation part light emitting part in the temperature adjustment operation unit is lit in red.

[0105] When the first temperature adjustment operation unit 92A is pressed for, for example, one second while the Peltier element PE is not energized, the heat transfer surface 61 enters a cooled state due to heat absorption by one surface PEA of the Peltier element PE, and the first operation unit light-emitting unit 130 lights up in blue as shown in Fig. 24. Even if the first temperature adjustment operation unit 92A is pressed for, for example, one second and the heat transfer surface 61 enters a cooled state due to heat absorption by one surface PEA of the Peltier element PE, the second operation unit light-emitting unit 131 remains off as shown in Fig. 24.

[0106] When the second temperature adjustment operation unit 92B is pressed for, for example, one second while the Peltier element PE is not energized, the heat transfer surface 61 enters a heated state due to heat generation on one surface PEA of the Peltier element PE, and the second operation unit light-emitting unit 131 lights up in red as shown in Fig. 25. Even if the second temperature adjustment operation unit 92B is pressed for, for example, one second and the heat transfer surface 61 enters a heated state due to heat generation on one surface PEA of the Peltier element PE, the first operation unit light-emitting unit 130 remains off as shown in Fig. 25.

[0107] <About the state in which the light-emitting part lights up when wearing the Temperature Regulation Vest 1> Fig. 26 explains the state in which the light emitting unit lights up when the temperature regulating vest is worn. Fig. 26 is an explanatory diagram for explaining the state in which the light emitting unit lights up when the temperature regulating vest is worn.

[0108] For example, if a malfunction occurs in the Peltier element unit 60 and the Peltier elements are unable to properly absorb heat and transfer it to the heat transfer surface 61, the heat transfer surface 61 will not cool, and the body of the wearer HM of the temperature regulating vest 1 will not be properly cooled. Furthermore, if, for example, a person behind the wearer HM has no way of confirming that the heat transfer surface 61 is in a cooled state, they may not notice that the wearer HM is feeling unwell in a muggy indoor environment in the dark, and may suffer from heatstroke. Therefore, if the heat transfer surface 61 is in a cooled state due to heat absorption by one surface PEA of the Peltier element PE, and the wearer HM of the temperature regulating vest 1 presses the first temperature adjustment operation unit 92A, for example, twice in succession, the first light-emitting unit 106 will light up blue. The blue light emitted by the first light-emitting unit 106 is scattered and passes through the main body 101 and the case 102 of the air blower 100, and is diffused to the outside of the main body 101 and the outside of the case 102, thereby brightly illuminating a wide area within the internal space IS of the storage unit 62. As a result, as shown in FIG. 26 , the blue light emitted LU from the first light-emitting unit 106 leaking from the exhaust hole 72 of the Peltier element unit 60 attached to the back body 5 of the temperature regulating vest 1 can be seen from the back side of the wearer HM of the temperature regulating vest 1. Therefore, in a dark, humid indoor environment, a person who sees the blue light emitted LU from the first light-emitting unit 106 leaking from the exhaust hole 72 can easily confirm that the heat transfer surface 61 is in a cooling state. Therefore, if the first light-emitting unit 106 is turned off, a person behind the wearer HM can call out to the wearer HM working in a dark, humid indoor environment to warn him or her to replace the Peltier element unit 60 with a new one. This can prevent the wearer HM working in a dark, humid indoor environment from suffering from heatstroke.

[0109] For example, if a malfunction occurs in the Peltier element unit 60 and the Peltier elements are unable to heat up normally and transfer heat to the heat transfer surface 61, the heat transfer surface 61 will not be heated, and the body of the wearer HM of the temperature regulating vest 1 will not be warmed properly. Furthermore, if a person behind the wearer HM has no way of confirming that the heat transfer surface 61 is in a heated state, they may not be able to notice that the wearer HM is feeling unwell in a cold, dark environment. Therefore, for example, if the heat transfer surface 61 is in a heated state due to heat generation on one surface PEA of the Peltier element PE, and the wearer HM of the temperature regulating vest 1 presses the second temperature adjustment operation unit 92B, for example, twice in succession, the second light-emitting unit 107 will light up in red. The red light emitted by the second light-emitting unit 107 scatters and passes through the main body 101 and the case 102 of the blower 100, diffusing to the outside of the main body 101 and the outside of the case 102, thereby brightly illuminating a wide area within the internal space IS of the storage unit 62. As a result, as shown in FIG. 26 , the red light emitted by the second light-emitting unit 107 leaking from the exhaust hole 72 of the Peltier element unit 60 attached to the back body 5 of the temperature regulating vest 1 can be seen from the back of the wearer HM of the temperature regulating vest 1. Therefore, in a dark and cold environment, a person who sees the red light emitted by the second light-emitting unit 107 leaking from the exhaust hole 72 can easily confirm that the heat transfer surface 61 is in a heated state. Therefore, if the second light-emitting unit 107 is turned off, a person behind the wearer HM, who is working in a dark and cold environment, can call out to the wearer HM and warn them to replace the Peltier element unit 60 with a new one. This helps to avoid the risk of the wearer (HM) becoming ill while working in a dark and cold environment.

[0110] <Regarding the light emission timing of one surface PEA of the Peltier element PE and the first light-emitting unit 106 and the second light-emitting unit 107> 27 to 30, the heat dissipation control of one surface PEA of the Peltier element PE and the control of the first operation unit light-emitting unit 130, the second operation unit light-emitting unit 131, the first light-emitting unit 106, and the second light-emitting unit 107 by operating the temperature adjustment operation unit 92 will be described (see FIGS. 33 to 36). FIG. 27 is a timing chart showing a first example of the heat dissipation control of one surface of the Peltier element, the control of the light-emitting unit, and the control of the operation unit light-emitting unit by operating the temperature adjustment operation unit. FIG. 28 is a timing chart showing a second example of the heat dissipation control of one surface of the Peltier element, the control of the light-emitting unit, and the control of the operation unit light-emitting unit by operating the temperature adjustment operation unit. FIG. 29 is a timing chart showing a third example of the heat dissipation control of one surface of the Peltier element, the control of the light-emitting unit, and the control of the operation unit light-emitting unit by operating the temperature adjustment operation unit. FIG. 30 is a timing chart showing a fourth example of the heat dissipation control of one surface of the Peltier element, the control of the light-emitting unit, and the control of the operation unit light-emitting unit by operating the temperature adjustment operation unit. 27 to 30, t0 to t8 indicate the transition of elapsed time.

[0111] In the case of the temperature regulating vest 1 according to this embodiment, as shown in Fig. 2, first to third Peltier element units 60A, 60B, 60C are attached to the back body 5. The Peltier elements PE housed in the housing portions 62 of the first to third Peltier element units 60A, 60B, 60C are all the same.

[0112] First, the cooling control of one surface PEA of the Peltier element PE by operating the first temperature adjustment operation part 92A and the control of the first light-emitting part 106 and the first operation part light-emitting part 130 will be described with reference to FIGS.

[0113] As shown in Fig. 27, when the Peltier element PE is not energized, if the detection by the first temperature adjustment operation unit switch 92AS continues for, for example, one second (see t1 in Fig. 27), the temperature adjustment control unit 91 supplies a direct current to the Peltier element PE in the forward direction (see Fig. 33). As a result, as shown in Fig. 27, the temperature adjustment control unit 91 controls one surface PEA of the Peltier element PE to absorb heat and place it in an endothermic state (cooled surface) (see t1 in Fig. 27). As a result, the heat transfer surface 61 cools due to the heat absorption by the one surface PEA of the Peltier element PE. Additionally, as shown in Fig. 27, the temperature adjustment control unit 91 lights only the first operation unit light-emitting unit 130 in blue (see t1 in Fig. 27 and Fig. 33).

[0114] The temperature adjustment control unit 91 continues to control the cooling surface of one surface PEA of the Peltier element PE unless the detection by the first temperature adjustment operation unit switch 92AS continues for, for example, one second (see t1 to t8 in FIG. 27).The temperature adjustment control unit 91 continues to emit blue light from the first operation unit light emitting unit 130 unless the detection by the first temperature adjustment operation unit switch 92AS continues for, for example, one second (see t1 to t8 in FIG. 27).

[0115] As shown in Fig. 28, when the Peltier element PE is not energized, if the detection by the first temperature adjustment operation unit switch 92AS continues for, for example, one second (see t1 in Fig. 28), the temperature adjustment control unit 91 supplies a direct current to the Peltier element PE in the forward direction (see Fig. 33). As a result, as shown in Fig. 28, the temperature adjustment control unit 91 controls one surface PEA of the Peltier element PE to absorb heat and enter an endothermic state (cooled surface) (see t1 in Fig. 28). As a result, the heat transfer surface 61 cools due to the heat absorption by the one surface PEA of the Peltier element PE. Additionally, as shown in Fig. 28, the temperature adjustment control unit 91 lights only the first operation unit light-emitting unit 130 in blue (see t1 in Fig. 28).

[0116] As shown in FIG. 28, when one surface PEA of the Peltier element PE is the cooling surface, if the first temperature adjustment operation unit switch 92AS detects this, for example, twice in succession, the temperature adjustment control unit 91 lights up the first light-emitting unit 106 in blue (see t3 in FIG. 28 and FIG. 35). Whether or not the first light-emitting unit 106 emits light can be selected depending on whether or not the wearer HM presses the first temperature adjustment operation unit 92A twice in succession when the heat transfer surface 61 is cooled. In this embodiment, when the heat transfer surface 61 is in the cooling state, the first operation unit light-emitting unit 130 and the first light-emitting unit 106 emit light in the same blue, allowing the wearer HM and a person behind the wearer HM to know that the heat transfer surface 61 is in the cooling state.

[0117] If one surface PEA of the Peltier element PE is the cooling surface and the detection by the first temperature adjustment operation unit switch 92AS does not continue for, for example, one second, the temperature adjustment control unit 91 continues to control the cooling surface of one surface PEA of the Peltier element PE (see t3 to t8 in FIG. 28). If one surface PEA of the Peltier element PE is the cooling surface and the detection by the first temperature adjustment operation unit switch 92AS does not continue for, for example, one second, the temperature adjustment control unit 91 continues to cause the first operation unit light-emitting unit 130 and the first light-emitting unit 106 to emit blue light (see t3 to t8 in FIG. 28).

[0118] Next, the heating control of one surface PEA of the Peltier element PE by operating the second temperature adjustment operation part 92B and the control of the second light-emitting part 107 and the second operation part light-emitting part 131 will be described with reference to FIGS.

[0119] As shown in Fig. 29, when the Peltier element PE is not energized, if the detection by the second temperature adjustment operation unit switch 92BS continues for, for example, one second (see t1 in Fig. 29), the temperature adjustment control unit 91 supplies a DC current to the Peltier element PE in the reverse direction (see Fig. 34). As a result, as shown in Fig. 29, the temperature adjustment control unit 91 controls one surface PEA of the Peltier element PE to generate heat and place it in a heated state (heated surface) (see t1 in Fig. 29). As a result, the heat transfer surface 61 is heated by the heat generated by the one surface PEA of the Peltier element PE. Additionally, as shown in Fig. 29, the temperature adjustment control unit 91 lights only the second operation unit light emitting unit 131 in red (see t1 in Fig. 29 and Fig. 34).

[0120] The temperature adjustment control unit 91 continues to control the heating surface of one surface PEA of the Peltier element PE unless the detection by the second temperature adjustment operation unit switch 92BS continues for, for example, one second (see t1 to t8 in FIG. 29).The temperature adjustment control unit 91 continues to emit red light from the second operation unit light emitting unit 131 unless the detection by the second temperature adjustment operation unit switch 92BS continues for, for example, one second (see t1 to t8 in FIG. 29).

[0121] As shown in Fig. 30, when the Peltier element PE is not energized, if the detection by the second temperature adjustment operation unit switch 92BS continues for, for example, one second (see t1 in Fig. 30), the temperature adjustment control unit 91 supplies a DC current to the Peltier element PE in the reverse direction (see Fig. 34). As a result, as shown in Fig. 30, the temperature adjustment control unit 91 controls one surface PEA of the Peltier element PE to generate heat and place it in a heated state (heated surface) (see t1 in Fig. 30). As a result, the heat transfer surface 61 is heated by the heat generated by the one surface PEA of the Peltier element PE. Additionally, as shown in Fig. 30, the temperature adjustment control unit 91 lights only the second operation unit light emitting unit 131 in red (see t1 in Fig. 30).

[0122] As shown in Fig. 30, when one surface PEA of the Peltier element PE is the heated surface, if the second temperature adjustment operation unit switch 92BS detects this, for example, twice in succession, the temperature adjustment control unit 91 lights up the second light-emitting unit 107 in red (see t3 in Fig. 30 and Fig. 36). Whether or not the second light-emitting unit 107 emits light can be selected depending on whether or not the wearer HM presses the second temperature adjustment operation unit 92B twice in succession when the heat transfer surface 61 is heated. In this embodiment, when the heat transfer surface 61 is in a heated state, the second operation unit light-emitting unit 131 and the second light-emitting unit 107 emit light in the same red, allowing the wearer HM and a person behind the wearer HM to know that the heat transfer surface 61 is in a heated state.

[0123] If one surface PEA of the Peltier element PE is the heating surface and detection by the second temperature adjustment operation unit switch 92BS does not continue for, for example, one second, the temperature adjustment control unit 91 continues to control the heating surface of one surface PEA of the Peltier element PE (see t3 to t8 in FIG. 30). If one surface PEA of the Peltier element PE is the heating surface and detection by the second temperature adjustment operation unit switch 92BS does not continue for, for example, one second, the temperature adjustment control unit 91 continues to emit red light from the second operation unit light-emitting unit 131 and the second light-emitting unit 107 (see t3 to t8 in FIG. 30).

[0124] <About the air blower operation unit> Fig. 31 is a block diagram showing the configuration of an air blow operation unit provided in a temperature regulating vest. As shown in Fig. 31, air blow operation unit 80 has an air blow control unit 81, an air blow operation unit 82, an air blow display unit 83, etc. Within air blow operation unit 80, air blow operation unit 82 and air blow display unit 83 are electrically connected to air blow control unit 81.

[0125] The air blowing operation section 82 is configured in a manner that enables operation to control the on / off switching operation of the power supply to the motor of the air blowing unit drive section 43 by lightly pressing a push-down section on the top surface of the air blowing operation unit 80 with a finger based on a predetermined operation mode. The air blowing display section 83 is a display section on the top surface of the air blowing operation unit 80, and is configured in a manner that allows it to emit light in white.

[0126] <About the temperature control unit> Fig. 32 is a block diagram showing the configuration of a temperature adjustment operation unit provided in a temperature adjustment vest. As shown in Fig. 32, a temperature adjustment operation unit 90 according to this embodiment includes a temperature adjustment control unit 91 electrically controlled by a temperature adjustment operation unit 92, a temperature adjustment operation unit 92, a temperature adjustment display unit 93, and the like. Within the temperature adjustment operation unit 90, the temperature adjustment operation unit 92 and the temperature adjustment display unit 93 are electrically connected to the temperature adjustment control unit 91. For example, the temperature adjustment operation unit 92 corresponds to the operation unit of the present disclosure. For example, the temperature adjustment control unit 91 corresponds to the control unit of the present disclosure.

[0127] The temperature adjustment operation unit 90 has a depressible temperature adjustment operation section 92 on its top surface. The temperature adjustment operation section 92 has a first temperature adjustment operation section 92A in the shape of a substantially equilateral triangle and a second temperature adjustment operation section 92B in the shape of a substantially inverted equilateral triangle. A first temperature adjustment operation section switch AS is built into the temperature adjustment operation section 92 as a switch that detects a depression operation of the first temperature adjustment operation section 92A. A second temperature adjustment operation section switch BS is built into the temperature adjustment operation section 92 as a switch that detects a depression operation of the second temperature adjustment operation section 92B.

[0128] The temperature adjustment display 93 is a display located on the top surface of the temperature adjustment operation unit 90 and is configured to be able to selectively emit light in a plurality of colors. Specifically, the temperature adjustment display 93 includes a first operation unit light-emitting element 130 that can emit light in blue and a second operation unit light-emitting element 131 that can emit light in red. As the light emitting elements constituting the first operation part light emitting part 130 and the second operation part light emitting part 131, for example, a bare chip type or a bullet type LED (Light Emitting Diode) is suitably used.

[0129] In the Peltier element unit 60, when the direction of the DC current supplied to the Peltier element PE is reversed, the functions of the one surface PEA and the other surface PEB are reversed. Therefore, if the temperature adjustment control unit 91 is configured to be able to reverse the polarity of the current supplied to the Peltier element PE, the heat transfer surface 61 can be selectively changed between the cooling surface 61A and the heating surface 61B by the temperature adjustment control unit 91. As a result, the cooling surface 61A and the heating surface 61B are interchangeable on the heat transfer surface 61. Note that if the temperature adjustment control unit 91 does not have the function of switching the direction of the current to the Peltier element PE, the heat transfer surface 61 is either the cooling surface 61A or the heating surface 61B.

[0130] <Regarding control by the temperature adjustment control unit 91> Next, control by the temperature adjustment control unit 91 will be described with reference to Figs. 33 to 36. Fig. 33 is a flowchart of the cooling control process by the temperature adjustment control unit. Fig. 34 is a flowchart of the heating control process by the temperature adjustment control unit. Fig. 35 is a flowchart of the first light emission control process by the temperature adjustment control unit. Fig. 36 is a flowchart of the second light emission control process by the temperature adjustment control unit.

[0131] The temperature adjustment control unit 91 can perform a cooling control process in which the heat transfer surface 61 is in a cooling state and a heating control process in which the heat transfer surface 61 is in a heating state, based on a pressing operation by the temperature adjustment operation unit 92. The temperature adjustment control unit 91 can perform a first light emission control process in which the first light emitting unit 106 emits light in blue, a second light emission control process in which the second light emitting unit 107 emits light in red, and the like, based on a pressing operation by the temperature adjustment operation unit 92.

[0132] First, with reference to FIG. 33, a cooling control process will be described in which the temperature adjustment control unit 91 supplies a forward direct current to the Peltier element PE to control the heat transfer surface 61 to a cooling state.

[0133] 33, in the cooling control process, the temperature adjustment control unit 91 first determines whether detection by the first temperature adjustment operation unit switch 92AS lasts for one second, i.e., whether a detection signal has been received by the first temperature adjustment operation unit switch 92AS for one second (S1). If the temperature adjustment control unit 91 determines that detection by the first temperature adjustment operation unit switch 92AS lasts for one second (YES in S1), it proceeds to step S2. On the other hand, if the temperature adjustment control unit 91 determines that detection by the first temperature adjustment operation unit switch 92AS does not last for one second (NO in S1), it simply ends the cooling control process.

[0134] 33, in the cooling control process, the temperature adjustment control unit 91 determines whether the heat transfer surface 61 is in a cooled state due to heat absorption by one surface PEA of the Peltier element PE (S2). Specifically, in step S2, the temperature adjustment control unit 91 determines whether a forward direct current is being supplied to the Peltier element PE. If the temperature adjustment control unit 91 determines in the cooling control process that the heat transfer surface 61 is not in a cooled state due to heat absorption by one surface PEA of the Peltier element PE (NO in S2), the process proceeds to step S3. On the other hand, if the temperature adjustment control unit 91 determines in the cooling control process that the heat transfer surface 61 is in a cooled state due to heat absorption by one surface PEA of the Peltier element PE (YES in S2), the process proceeds to step S6.

[0135] In step S3, the temperature adjustment control section 91 controls the first to third Peltier element units 60A, 60B, 60C to turn on the power supply to the Peltier elements PE, supplies direct current in the forward direction, and proceeds to step S4. By performing step S3, one surface PEA of the Peltier element PE absorbs heat to, for example, about 10°C due to the Peltier effect in the flat plate portion of the Peltier element PE, and enters an endothermic state (cooled surface), and the heat transfer surface 61 enters a cooled state.

[0136] Next, in step S4, the temperature adjustment control section 91 outputs a signal to the control board 105 in the first to third Peltier element units 60A, 60B, 60C to drive the drive motors 104, and the process proceeds to step S5. The control board 105 drives the drive motors 104 based on the signal to drive the drive motors 104. Driving the drive motors 104 causes the propellers 103 to rotate, and air is sent out toward the exhaust holes 72.

[0137] Next, in step S5, the temperature adjustment control unit 91 outputs a signal to cause the first operation unit light emitting unit 130 to emit blue light, lighting the first operation unit light emitting unit 130 in blue, and ends the cooling control process. This allows the wearer HM of the temperature adjustment vest 1 to visually recognize that the first operation unit light emitting unit 130 is emitting blue light.

[0138] If the temperature adjustment control unit 91 determines that the heat transfer surface 61 is in the cooling state (YES in S2), in step S6, it controls the first to third Peltier element units 60A, 60B, 60C to turn off the power supply to the Peltier elements PE, and then proceeds to step S7, whereby the cooling state by the heat transfer surface 61 ends.

[0139] Subsequently, in step S7, the temperature adjustment control unit 91 outputs a signal to turn off the first operation unit light-emitting unit 130, thereby turning off the first operation unit light-emitting unit 130, and ends the cooling control process. Note that in step S7, if the first operation unit light-emitting unit 130 and the first light-emitting unit 106 are lit in blue, the temperature adjustment control unit 91 outputs a signal to make the first operation unit light-emitting unit 130 emit light in blue, thereby turning off the first operation unit light-emitting unit 130. Additionally, in step S7, the temperature adjustment control unit 91 outputs a signal to the control boards 105 of the first to third Peltier element units 60A, 60B, and 60C to turn off the first operation unit light-emitting unit 130. As a result, when the control board 105 receives the signal, the first light-emitting unit 106 turns off.

[0140] Next, a heating control process in which the temperature adjustment control unit 91 supplies a reverse direct current to the Peltier element PE to control the heat transfer surface 61 to a heated state will be described with reference to FIG.

[0141] 34, in the heating control process, the temperature adjustment control unit 91 first determines whether the detection by the second temperature adjustment operation unit switch 92BS lasted for one second, i.e., whether a detection signal was received by the second temperature adjustment operation unit switch 92BS for one second (S10). If the temperature adjustment control unit 91 determines that the detection by the second temperature adjustment operation unit switch 92BS lasted for one second (YES in S10), it proceeds to step S11. On the other hand, if the temperature adjustment control unit 91 determines that the detection by the second temperature adjustment operation unit switch 92BS did not last for one second (NO in S10), it simply ends the heating control process.

[0142] 34, in step S11, the temperature adjustment control unit 91 determines whether the heat transfer surface 61 is in a heated state due to heat generation from one surface PEA of the Peltier element PE. Specifically, in step S11, the temperature adjustment control unit 91 determines whether a reverse direct current is being supplied to the Peltier element PE. If the temperature adjustment control unit 91 determines in the heating control process that the heat transfer surface 61 is not in a heated state due to heat generation from one surface PEA of the Peltier element PE (NO in S11), the temperature adjustment control unit 91 proceeds to step S12. On the other hand, if the temperature adjustment control unit 91 determines in the heating control process that the heat transfer surface 61 is in a heated state due to heat generation from one surface PEA of the Peltier element PE (YES in S11), the temperature adjustment control unit 91 proceeds to step S15.

[0143] In step S12, the temperature adjustment control section 91 controls the first to third Peltier element units 60A, 60B, 60C to turn on the power supply to the Peltier element PE, supplies DC current in the reverse direction, and proceeds to step S13. By performing step S12, one surface PEA of the Peltier element PE heats up to, for example, about 30°C due to the Peltier effect, and enters a heated state (heated surface), and the heat transfer surface 61 enters a heated state.

[0144] Next, in step S13, the temperature adjustment control section 91 outputs a signal to the control board 105 in the first to third Peltier element units 60A, 60B, 60C to drive the drive motors 104, and the process proceeds to step S14. The control board 105 drives the drive motors 104 based on the signal to drive the drive motors 104. Driving the drive motors 104 causes the propellers 103 to rotate, and air is sent out toward the exhaust holes 72.

[0145] Next, in step S14, the temperature adjustment control unit 91 outputs a signal to cause the second operation unit light emitting unit 131 to emit light in red, lighting the second operation unit light emitting unit 131 in red, and ends the heating control process. This allows the wearer HM of the temperature adjustment vest 1 to visually recognize that the second operation unit light emitting unit 131 is emitting light in red.

[0146] If the temperature adjustment control unit 91 determines that the heat transfer surface 61 is in a heated state (YES in S11), in step S15 it controls the first to third Peltier element units 60A, 60B, 60C to turn off the power supply to the Peltier elements PE, and then proceeds to step S16, which ends the heating state by the heat transfer surface 61.

[0147] Subsequently, in step S16, the temperature adjustment control unit 91 outputs a signal to turn off the second operation unit light-emitting unit 131, thereby turning off the second operation unit light-emitting unit 131, and ends the heating control process. Note that in step S16, if the second operation unit light-emitting unit 131 and the second light-emitting unit 107 are lit in red, the temperature adjustment control unit 91 outputs a signal to make the second operation unit light-emitting unit 131 emit light in red, thereby turning off the second operation unit light-emitting unit 131. Additionally, in step S16, the temperature adjustment control unit 91 outputs a signal to the control boards 105 of the first to third Peltier element units 60A, 60B, and 60C to turn off the second operation unit light-emitting unit 131. As a result, when the control board 105 receives the signal, the second light-emitting unit 107 turns off.

[0148] Next, the first light emission control process by the temperature adjustment control unit 91 based on the operation of the first temperature adjustment operation unit 92A when the heat transfer surface 61 is in the cooled state will be described with reference to FIG.

[0149] 35, in the first light-emission control process, the temperature adjustment control unit 91 determines whether the heat transfer surface 61 is in a cooled state due to heat absorption by one surface PEA of the Peltier element PE (S20). Specifically, in step S20, the temperature adjustment control unit 91 determines whether a forward direct current is being supplied to the Peltier element PE. If the temperature adjustment control unit 91 determines in the first light-emission control process that the heat transfer surface 61 is in a cooled state due to heat absorption by one surface PEA of the Peltier element PE (YES in S20), the process proceeds to step S21. On the other hand, if the temperature adjustment control unit 91 determines in the first light-emission control process that the heat transfer surface 61 is not in a cooled state due to heat absorption by one surface PEA of the Peltier element PE (NO in S20), the process ends the first light-emission control process.

[0150] 35, in step S21, the temperature adjustment control unit 91 determines whether or not the first temperature adjustment operation unit switch 92AS has detected twice consecutively, i.e., whether or not the first temperature adjustment operation unit switch 92AS has received two consecutive detection signals (S21). If the temperature adjustment control unit 91 determines in step S21 that the first temperature adjustment operation unit switch 92AS has detected twice consecutively (YES in S21), the temperature adjustment control unit 91 proceeds to step S22. On the other hand, if the temperature adjustment control unit 91 determines in step S21 that the first temperature adjustment operation unit switch 92AS has not detected twice consecutively (NO in S21), the temperature adjustment control unit 91 ends the first light-emission control process.

[0151] In step S22, the temperature adjustment control unit 91 outputs a signal to the control board 105 to light up the first light-emitting unit 106 in blue (S22), and ends the first light-emitting control process. When the control board 105 receives the signal to light up the first light-emitting unit 106 in blue output from the temperature adjustment control unit 91, the first light-emitting unit 106 lights up in blue.

[0152] Next, the second light emission control process by the temperature adjustment control unit 91 based on the operation of the second temperature adjustment operation unit 92B when the heat transfer surface 61 is in a heated state will be described with reference to FIG.

[0153] 36, in the second light-emission control process, the temperature adjustment control unit 91 determines whether the heat transfer surface 61 is in a heated state due to heating of one surface PEA of the Peltier element PE (S30). Specifically, in step S30, the temperature adjustment control unit 91 determines whether a reverse direct current is being supplied to the Peltier element PE. If the temperature adjustment control unit 91 determines in the second light-emission control process that the heat transfer surface 61 is in a heated state due to heat generation of one surface PEA of the Peltier element PE (YES in S30), the process proceeds to step S31. On the other hand, if the temperature adjustment control unit 91 determines in the second light-emission control process that the heat transfer surface 61 is not in a heated state due to heat generation of one surface PEA of the Peltier element PE (NO in S30), the second light-emission control process ends.

[0154] 36, in step S31, the temperature adjustment control unit 91 determines whether or not the second temperature adjustment operation unit switch 92BS has detected the light twice consecutively, i.e., whether or not the second temperature adjustment operation unit switch 92BS has received a detection signal twice consecutively (S31). If the temperature adjustment control unit 91 determines in step S31 that the second temperature adjustment operation unit switch 92BS has detected the light twice consecutively (YES in S31), the temperature adjustment control unit 91 proceeds to step S32. On the other hand, if the temperature adjustment control unit 91 determines in step S31 that the second temperature adjustment operation unit switch 92BS has not detected the light twice consecutively (NO in S31), the temperature adjustment control unit 91 ends the second light emission control process.

[0155] In step S32, the temperature adjustment control unit 91 outputs a signal to the control board 105 to turn on the second light-emitting unit 107 in red (S32), and ends the second light-emission control process. When the control board 105 receives the signal to turn on the second light-emitting unit 107 in red output from the temperature adjustment control unit 91, the second light-emitting unit 107 turns on in red.

[0156] Next, the functions and effects of the Peltier element unit 60 and the temperature regulating vest 1 according to this embodiment will be described.

[0157] The Peltier element unit 60 includes a Peltier element PE according to this embodiment, a heat transfer surface 61 that transfers heat absorbed by one surface PEA of the Peltier element PE when electricity is applied, and a temperature adjustment operation unit 92. The Peltier element unit 60 also includes a temperature adjustment control unit 91 that electrically controls the temperature adjustment operation unit 92, a storage unit 62 that stores the Peltier element PE, a heat exchange surface 73 on the opposite side of the heat transfer surface 61, an air intake hole 65a that takes in air from outside the storage unit 62, and an exhaust hole 72 that exhausts the air taken in through the air intake hole 65a to the outside of the storage unit 62. A first light-emitting unit 106 is disposed inside the storage unit 62, and the temperature adjustment control unit 91 can cause the first light-emitting unit 106 to emit light by pressing the first temperature adjustment operation unit 92A when the heat transfer surface 61 is in a cooled state due to heat absorption by one surface PEA of the Peltier element PE.

[0158] According to the Peltier element unit 60 of this embodiment, when the heat transfer surface 61 is cooled by absorbing heat on one surface PEA of the Peltier element PE by operating the first temperature adjustment operation unit 92A twice in succession, the light emitted from the first light-emitting unit 106 becomes visible through the exhaust hole 72. As a result, for example, when a person using the Peltier element unit 60 is working in the dark, a person behind the wearer HM can see the light emitted from the exhaust hole 72. Therefore, in a dark, humid indoor environment, a person who sees the light emitted by the first light-emitting unit 106 leaking from the exhaust hole 72 can easily confirm that the heat transfer surface 61 is properly cooled. Therefore, a Peltier element unit 60 can be provided in which the light emitted from the first light-emitting unit 106 alerts a person behind the wearer HM that the heat transfer surface 61 is cooled, thereby preventing the wearer HM working in a dark, humid indoor environment from suffering from heatstroke.

[0159] In the Peltier element unit 60 of this embodiment, when electricity is applied, heat generated on one surface PEA of the Peltier element PE is transferred to the heat transfer surface 61, and the temperature adjustment control unit 91, by operating the first temperature adjustment operation unit 92A, can cause the first light-emitting unit 106 to emit blue light when the heat transfer surface 61 is in a cooled state due to heat absorption on one surface PEA of the Peltier element PE, and by operating the second temperature adjustment operation unit 92B, can cause the second light-emitting unit 107 to emit red light when the heat transfer surface 61 is in a heated state due to heat generation on one surface PEA of the Peltier element PE.

[0160] According to the Peltier element unit 60 of this embodiment, when the heat transfer surface 61 is in a cooling state, two consecutive operations of the first temperature adjustment operation unit 92A make the blue light emitted by the first light-emitting unit 106 visible through the exhaust hole 72. As a result, for example, when the wearer HM is working in the dark, a person behind the wearer HM can see the colored light leaking from the exhaust hole 72. Therefore, in a dark, humid indoor environment, a person who sees the blue light leaking from the exhaust hole 72 can easily confirm that the heat transfer surface 61 is normally in a cooling state. On the other hand, when the heat transfer surface 61 is in a heating state, two consecutive operations of the second temperature adjustment operation unit 92B make the red light emitted by the second light-emitting unit 107 visible through the exhaust hole 72. As a result, for example, when the wearer HM is working in the dark, a person behind the wearer HM can see the red light leaking from the exhaust hole 72. Therefore, in a dark and cold environment, a person who sees the red light leaking from the exhaust hole 72 can easily confirm that the heat transfer surface 61 is in a normal heating state. Therefore, the difference in the light emission colors of the first light-emitting portion 106 and the second light-emitting portion 107 can avoid the risk of the wearer HM working in a dark and humid environment as well as in a dark and cold environment becoming ill.

[0161] In the Peltier element unit 60 according to this embodiment, the Peltier element unit 60 has a ceiling portion 71 that closes the internal space IS surrounded by the accommodation portion 62 on the side opposite the heat transfer surface 61, and the accommodation portion 62 accommodates a blower 100 that takes in air through an intake hole 65a and sends it out toward an exhaust hole 72, and the exhaust hole 72 is disposed in the ceiling portion 71, and the blower 100 comprises a main body portion 101 that accommodates a first light-emitting portion 106, a case portion 102 having a propeller 103, and a drive motor 104 that rotates the propeller 103.

[0162] According to the Peltier element unit 60 of this embodiment, an exhaust hole 72 is provided in a ceiling portion 71 that closes the interior space IS, which is surrounded by a housing portion 62 having a first light-emitting portion 106 inside the blower 100, on the side opposite to the heat transfer surface 61. This makes it difficult for dust or the like that has entered the housing portion 62 of the Peltier element unit 60 to come into contact with the first light-emitting portion 106 that is housed in the main body portion 101 of the blower 100. This makes it difficult for dust or the like that has entered the housing portion 62 to affect the light emission of the first light-emitting portion 106. This makes it possible to provide a situation in which a person behind the wearer HM can easily see the blue light emitted by the first light-emitting portion 106 from the ceiling portion 71.

[0163] In the Peltier element unit 60 according to this embodiment, the Peltier element unit 60 accommodates in the accommodation section 62 a blower 100 that takes in air through the intake hole 65a and sends it out towards the exhaust hole 72, and the blower 100 comprises a main body section 101 that accommodates a first light-emitting section 106, a case section 102 having a propeller 103, and a drive motor 104 that rotates the propeller 103, and the main body section 101 is formed in a manner that allows light emitted by the first light-emitting section 106 to pass outside the main body section 101.

[0164] According to the Peltier element unit 60 of this embodiment, the light emitted from the first light emitter 106 housed in the main body 101 of the blower 100 passes outside the main body 101, brightly illuminating the interior space IS of the housing 62 over a wide area. This makes it easier for a person behind the wearer HM to see the light leaking from the exhaust hole 72, for example, when the wearer HM is working in the dark. Therefore, by absorbing heat on one surface PEA of the Peltier element PE and making it easier to confirm that the heat transfer surface 61 is in a normal cooling state, the risk of heat stroke for workers working in hot and humid indoor environments can be further reduced.

[0165] In the Peltier element unit 60 according to this embodiment, the case part 102 is formed in a manner that allows light emitted by the first light emitting part 106 to pass to the outside of the case part 102 .

[0166] According to the Peltier element unit 60 of this embodiment, the light emitted from the first light emitter 106 housed in the main body 101 of the blower 100 passes not only outside the main body 101 but also outside the case 102, thereby illuminating the interior space IS of the housing 62 over a wider area. This makes it easier for a person behind the wearer HM to see the light leaking from the exhaust hole 72, for example, when the wearer HM is working in the dark. Therefore, by absorbing heat on one surface PEA of the Peltier element PE and making it easier to confirm that the heat transfer surface 61 is in a normal cooling state, the risk of heat stroke for workers working in a humid indoor environment can be further reduced.

[0167] The temperature regulating vest 1 according to this embodiment is a garment in which a Peltier element unit 60 can be attached to the inner fabric 3B.

[0168] According to the temperature regulating vest 1 of this embodiment, when the heat transfer surface 61 is cooled due to heat absorption by one surface PEA of the Peltier element PE by operating the first temperature adjustment operation unit 92A twice in succession, the light emitted by the first light emitter 106 becomes easily visible through the exhaust holes 72. As a result, for example, when a wearer HM of the temperature regulating vest 1 is working in the dark, a person behind the wearer HM can see the blue light leaking from the exhaust holes 72 and confirm that the heat transfer surface 61 is normally cooled. This allows confirmation that the heat transfer surface 61 of the Peltier element unit 60 attached to the back fabric 3B of the temperature regulating vest 1 is normally cooled, and the risk of heat stroke can be avoided for the wearer HM working in the dark in a muggy indoor environment, for example.

[0169] Although the present disclosure has been described above 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 spirit of the present disclosure. Of course, the configurations of the first embodiment and the following modified examples may be appropriately combined. Technical features of the first embodiment and the following modified examples may be appropriately deleted unless they are described as essential in this specification.

[0170] In the above embodiment, the number of air blowing units 40 attached to the vest body 2 may be two or more, and is not limited to the embodiment but can be variously modified. Also, the number of Peltier element units 60 attached to the vest body 2 may be two or less, or four or more, and is not limited to the embodiment but can be variously modified.

[0171] In the above embodiment, the air blowing unit 40 and the Peltier element unit 60 can be attached to the vest body 2. However, this is not limited to this. For example, the vest body 2 may be able to be attached with only one of the air blowing unit 40 or the Peltier element unit 60.

[0172] In the above embodiment, the number of first light-emitting units 106 arranged inside one Peltier element unit 60 may be 1 or may be 3 or more, and is not limited to the embodiment but can be variously modified. In the above embodiment, the number of second light-emitting units 107 arranged inside one Peltier element unit 60 may be 1 or may be 3 or more, and is not limited to the embodiment but can be variously modified.

[0173] In the above embodiment, the first light-emitting unit 106 and the second light-emitting unit 107 are housed in the air blower 100, but this is not limitative. For example, as long as the Peltier element unit 60 can normally regulate the body temperature, they may be disposed in a location other than the air blower 100 inside the housing 62. This allows opaque materials to be used as the components of the main body 101 and the case 102 of the air blower 100.

[0174] In the above embodiment, to light up the first light-emitting unit 106, the first temperature adjustment operation unit 92A must be pressed, for example, twice in succession, when the heat transfer surface 61 is cooled due to heat absorption by one surface PEA of the Peltier element PE. However, this is not limited to this. For example, other operation methods for the temperature adjustment operation unit 92 to light up the first light-emitting unit 106 may be adopted as long as it is possible to prevent confusion with the operation method for the temperature adjustment operation unit 92 related to the supply of direct current to the Peltier element PE. For example, the temperature adjustment control unit 91 may cause the first light-emitting unit 106 to emit blue light when a predetermined time (e.g., 10 seconds) has elapsed since the heat transfer surface 61 was cooled due to heat absorption by one surface PEA of the Peltier element PE. This allows the blue light emitted from the exhaust hole 72 to be seen by a person behind the wearer HM, even if the first temperature adjustment operation unit 92A is not pressed down by a person.

[0175] In the above embodiment, to light up the second light-emitting unit 107, the second temperature adjustment operation unit 92B must be pressed, for example, twice in succession, when the heat transfer surface 61 is heated due to heat generated by one surface PEA of the Peltier element PE. However, this is not limited to this. For example, other operation methods for the temperature adjustment operation unit 92 for lighting up the second light-emitting unit 107 may be adopted as long as it is possible to prevent confusion with the operation method for the temperature adjustment operation unit 92 related to the supply of direct current to the Peltier element PE. For example, the temperature adjustment control unit 91 may cause the second light-emitting unit 107 to emit red light when a predetermined time (e.g., 10 seconds) has elapsed since the heat transfer surface 61 was heated due to heat generated by one surface PEA of the Peltier element PE. This allows a person behind the wearer HM to see the red light emitted from the exhaust hole 72, even if the second temperature adjustment operation unit 92B is not pressed down by the person.

[0176] In the above embodiment, the method of operating the temperature adjustment operation unit 92 related to the supply of DC current to the Peltier element PE was to press the temperature adjustment operation unit 92 for, for example, one second. However, this is not limited to this. For example, other methods may be used as the method of operating the temperature adjustment operation unit 92 related to the supply of DC current to the Peltier element PE, as long as it is possible to prevent a person from mistaking this method for the method of operating the temperature adjustment operation unit 92 related to the light emission of the first light-emitting unit 106 or the second light-emitting unit 107.

[0177] In the above embodiment, different light-emitting elements were illuminated when the first temperature adjustment operation unit 92A was pressed, for example, twice in succession, while the heat transfer surface 61 was in the cooling state, and when the second temperature adjustment operation unit 92B was pressed, for example, twice in succession, while the heat transfer surface 61 was in the heating state. However, this is not limited to this. For example, the same light-emitting element may be illuminated when the first temperature adjustment operation unit 92A was pressed, for example, twice in succession, while the heat transfer surface 61 was in the cooling state, and when the second temperature adjustment operation unit 92B was pressed, for example, twice in succession, while the heat transfer surface 61 was in the heating state. This reduces the number of components in the Peltier element unit, thereby reducing the manufacturing cost of the Peltier element unit.

[0178] In the above embodiment, when the first temperature adjustment operation unit 92A is pressed twice in succession on the cooling surface 61A, the first light-emitting unit 106 lights up in blue, and when the second temperature adjustment operation unit 92B is pressed twice in succession on the heating surface 61B, the second light-emitting unit 107 lights up in red. However, this is not limited to this. For example, the light colors of the first light-emitting unit 106 and the second light-emitting unit 107 may be changed as appropriate as long as they are different. For example, when the first temperature adjustment operation unit 92A is pressed twice in succession on the cooling surface 61A, the first light-emitting unit 106 may continue to light up, and when the second temperature adjustment operation unit 92B is pressed twice in succession on the heating surface 61B, the second light-emitting unit 107 may flash. For example, when the first temperature adjustment operation unit 92A is pressed twice in succession on the cooling surface 61A, the first light-emitting unit 106 may light up for, for example, 30 seconds, and when the second temperature adjustment operation unit 92B is pressed twice in succession on the heating surface 61B, the second light-emitting unit 107 may light up for, for example, 10 seconds.

[0179] In the above embodiment, the main body 101 of the blower 100 is formed of a translucent material that scatters the light emitted by the first light-emitting unit 106 and the second light-emitting unit 107 as it passes through the main body 101 and diffuses it to the outside of the main body 101. However, this is not limited to this. For example, the main body 101 may be formed of a transparent material that allows the light emitted by the first light-emitting unit 106 and the second light-emitting unit 107 to pass completely through the main body 101. This allows the light emitted by the first light-emitting unit 106 and the light emitted by the second light-emitting unit 107 to illuminate a wider area within the internal space IS of the storage unit 62.

[0180] In the above embodiment, the case 102 of the blower 100 is formed of a translucent material that scatters the light emitted by the first light-emitting unit 106 and the second light-emitting unit 107 as it passes through the case 102 and diffuses outside the case 102. However, this is not limited to this. For example, the case 102 may be formed of a transparent material that allows the light emitted by the first light-emitting unit 106 and the second light-emitting unit 107 to pass completely through the case 102. This allows the light emitted by the first light-emitting unit 106 and the light emitted by the second light-emitting unit 107 to illuminate a wider area within the internal space IS of the storage unit 62.

[0181] In the above embodiment, the first light-emitting unit 106 and the second light-emitting unit 107 are housed in the main body 101 of the blower device 100. However, this is not limited to this. For example, the first light-emitting unit 106 and the second light-emitting unit 107 may be housed in the casing 44 of the blower fan 42. In addition, for example, the rotation speed of the propeller of the blower fan 42 may be changed in multiple stages by operating the blower operation unit 82. Thus, for example, when the propeller of the blower fan 42 is rotating at a first rotation speed, the blower control unit 81 may cause the first light-emitting unit 106 to emit light in blue by operating the blower operation unit 82. On the other hand, for example, when the propeller of the blower fan 42 is rotating at a second rotation speed that is higher than the first rotation speed, the blower control unit 81 may cause the second light-emitting unit 107 to emit light in red by operating the blower operation unit 82. As a result, in a dark, humid indoor environment, the color of the light leaking from intake hole 46a makes it possible to confirm the rotation speed of the propeller of blower fan 42 and the normal operation of blower fan 42. Therefore, a wearer HM of temperature regulating vest 1 equipped with blower fan 42 can regulate the body temperature of a worker or the like working in a dark, humid environment.

[0182] In the above embodiment, the temperature adjustment control unit 91 causes the first light-emitting unit 106 to emit blue light when the first temperature adjustment operation unit 92A is pressed, for example, twice in succession, while the heat transfer surface 61 is in the cooling state. However, this is not limited to this. For example, when no direct current is supplied to the Peltier element PE in the forward direction, the temperature adjustment control unit 91 may supply direct current to the Peltier element PE in the forward direction and cause the first light-emitting unit 106 to emit blue light when the first temperature adjustment operation unit 92A is operated for, for example, one second. In this case, when the first light-emitting unit 106 is emitting blue light, it may be possible to select whether to turn on or off the first light-emitting unit 106 depending on whether the first temperature adjustment operation unit 92A is pressed.

[0183] In the above embodiment, the temperature adjustment control unit 91 causes the second light-emitting unit 107 to emit red light when the second temperature adjustment operation unit 92B is pressed, for example, twice in succession, while the heat transfer surface 61 is in a heated state. However, this is not limited to this. For example, when a direct current is not being supplied to the Peltier element PE, the temperature adjustment control unit 91 may supply a direct current in the reverse direction to the Peltier element PE and cause the second light-emitting unit 107 to emit red light when the second temperature adjustment operation unit 92B is operated for, for example, one second. In this case, when the second light-emitting unit 107 is emitting red light, it may be possible to select whether to turn on or off the second light-emitting unit 107 depending on whether the second temperature adjustment operation unit 92B is pressed.

[0184] In the above embodiment, when the temperature adjustment control unit 91 turns on the first light-emitting unit 106 in blue, the temperature adjustment control unit 91 may turn off the first light-emitting unit 106 after a predetermined time (for example, one minute) has elapsed since the first light-emitting unit 106 turned on in blue. In this way, by limiting the lighting time of the first light-emitting unit 106, the power consumption of the Peltier element unit 60 can be reduced.

[0185] In the above embodiment, when the second light-emitting unit 107 is lit in red, the temperature adjustment control unit 91 may turn off the second light-emitting unit 107 after a predetermined time (for example, one minute) has elapsed since the second light-emitting unit 107 was lit in red. In this way, by limiting the lighting time of the second light-emitting unit 107, the power consumption of the Peltier element unit 60 can be reduced.

[0186] In the above embodiment, the number of protrusions 122 was four. However, this is not limited to this. For example, the number of protrusions 122 may be three or less, or five or more. However, it is preferable that the number of protrusions 122 is the same as the number of guide rails 66. This is because if the number of protrusions 122 and the number of guide rails 66 were to differ, it would be difficult to attach the Peltier element unit 60 to the temperature regulating vest 1.

[0187] In the above embodiment, the number of guide rails 66 was four. However, this is not limited to this. For example, the number of guide rails 66 may be three or less, or five or more. However, it is preferable that the number of guide rails 66 is the same as the number of protrusions 122. This is because if the number of protrusions 122 and the number of guide rails 66 were different, it would be difficult to attach the Peltier element unit 60 to the temperature regulating vest 1.

[0188] In the above embodiment, the number of restricting portions 67 provided on each of the plurality of sliding surfaces 68 was four. However, this is not limited to this. For example, the number of restricting portions 67 provided on each of the plurality of sliding surfaces 68 may be three or less, or five or more.

[0189] In the above embodiment, the number of gaps 70 is four. However, this is not limitative. For example, the number of gaps 70 may be three or less, or five or more.

[0190] In the above embodiment, the inclination angle θ1 between one end 66a and the other end 66b of the sliding surface 68 of all of the multiple guide rails 66 is set to 3°. However, this is not limited to this. For example, the inclination angle θ1 between one end and the other end of the sliding surface 68 of all of the multiple guide rails may be less than 3° or may exceed 3°. However, if the inclination angle θ1 is less than 1°, there will be no difference in height between one end and the other end of the guide rail, which is not preferable because it will be unable to accommodate various fabric thicknesses. On the other hand, if the inclination angle θ1 is 10° or more, it will be difficult to sandwich the fabric of the temperature regulating vest 1 and attach it to the temperature regulating vest 1, which is not preferable.

[0191] In the above embodiment, the housing portion 62 of the Peltier element unit 60 and the ring fastener 120 are rotated relative to each other, and with the inner flange 63 and the ring fastener 120 sandwiching the back fabric 3B and the second outer peripheral edge portion 31, each of the multiple protrusions 122 engages with each of the restricting portions 67. As a result, the Peltier element unit 60 is attached to the temperature regulating vest 1 with the inner flange 63 and the ring fastener 120 sandwiching the back fabric 3B and the second outer peripheral edge portion 31. However, this is not limited to this. For example, a structure may be used in which the back fabric 3B and the second outer peripheral edge portion 31 are sandwiched between the housing portion 62 of the Peltier element unit 60 and the ring fastener 120, and the housing portion 62 and the ring fastener 120 are fixed by screwing. Alternatively, for example, the structure may be such that the lining fabric 3B and the second outer peripheral edge portion 31 are sandwiched between the accommodation portion 62 of the Peltier element unit 60 and the ring fastener 120, and the convex portion of the ring fastener 120 is engaged with the concave portion of the accommodation portion 62 to fix them. Alternatively, for example, the structure may be such that the person's wear is sandwiched between the accommodation portion 62 of the Peltier element unit 60 and the ring fastener 120, and the concave portion of the ring fastener 120 is engaged with the convex portion of the accommodation portion 62 to fix them.

[0192] In the above embodiment, the inner flange 63 is inclined toward the ceiling portion 71 with respect to a plane perpendicular to the heat transfer surface 61 (cooling surface 61A or heating surface 61B). However, this is not limited to this. For example, the inner flange 63 and the outer flange 121 may be parallel to the heat transfer surface 61 (cooling surface 61A or heating surface 61B).

[0193] In the above embodiment, the vest body 2 has a single first attachment portion 20 provided on the lining fabric 3B of the fabric 3. However, this is not limited to this. The number, placement positions, and arrangement of the first attachment portions provided on the fabric can be changed as appropriate depending on the specifications of the product, such as the use of the body temperature regulating garment (product) according to the present disclosure and the physique of the wearer.

[0194] In the above embodiment, the vest body 2 has the second attachment portions 30 provided at three locations on the lining fabric 3B of the fabric 3. However, this is not limited to this. The number, placement positions, and arrangement of the second attachment portions on the fabric can be changed as appropriate depending on the specifications of the product, such as the use of the body temperature regulating garment (product) according to the present disclosure and the physique of the wearer.

[0195] In the above embodiment, the temperature regulation vest 1 has been described as an example of a temperature regulation wearing device in the present disclosure, but the present disclosure is not limited to this. For example, an example of a temperature regulation wearing device in the present disclosure may be a wearing device worn around the neck, arm, or the like to which the Peltier element unit 60 can be attached. [Industrial Applicability]

[0196] As is clear from the above explanation, by making it easier to confirm that the heat transfer surface is being cooled by heat absorption on one side of the Peltier element, the risk of heat stroke for workers working in a dark, humid indoor environment can be avoided. Therefore, the present invention has industrial applicability. [Explanation of symbols]
