Description

The present disclosure relates to a clothing attachment structure for a body temperature regulating device intended for body temperature regulating clothing in which a body temperature regulating device is attached to clothing worn on the body, such as a jacket, vest, or trousers, and to body temperature regulating clothing constructed with this structure.

In recent years, there have been many extremely hot days throughout the year that are uncomfortable for people, and on such extremely hot days, frequent hydration and moderate use of air conditioning devices are encouraged as measures to prevent heatstroke. However, due to reasons such as the lack of air conditioning equipment or insufficient air conditioning, workers who work outdoors in the heat of the day, workers who work in muggy indoor environments, and people who engage in recreational activities, sports, or watching events under the blazing sun cannot cool down with air conditioning devices. For this reason, many body temperature regulating garments with body temperature regulation units have been developed in recent years for people seeking to escape the heat. Patent Document 1 discloses air-conditioned clothing, an example of such body temperature regulating clothing.

Patent Document 1 discloses an air-conditioned garment with an air-conditioned garment blowing unit attached to the garment fabric. The air-conditioned garment blowing unit includes a casing that covers the propeller that blows air and the drive unit that controls its rotation in a breathable manner, a main body with a flange at its end and a male thread on its outer periphery, and an annular pressing member with a female thread on its inner periphery. In Patent Document 1, the casing of the main body is inserted into the opening of the fabric from the outside of the fabric of the air-conditioned garment, and the pressing member is placed from the inside of the fabric toward the casing of the main body with the flange of the main body abutting against the outer periphery of the opening of the fabric. Then, the male thread of the casing of the main body is screwed into the female thread of the pressing member to fix the main body and the pressing member, so that the air-conditioned garment blowing unit is attached with the fabric of the air-conditioned garment sandwiched between the flange of the main body and the pressing member.

Utility Model Registration No. 3213564

In the air-conditioned clothing of Patent Document 1, the fabric of the air-conditioned clothing is sandwiched between the main body of the air-conditioned clothing blower unit (body temperature adjustment device) and a pressure member that is separate from the main body, and the main body side and the pressure member side are screwed together to fix them. Therefore, the technology of Patent Document 1 has the following problems.
The problem is that when screwing the main body of the air-conditioned clothing air-blowing unit into the pressing member, if the pressing member becomes loose or not properly tightened, the air-conditioned clothing air-blowing unit may fall off the air-conditioned clothing or the pressing member may be lost, making it difficult for the worker to use.

The present disclosure has been made to solve the above problems, and aims to provide a clothing attachment structure for a body temperature regulating device that simplifies attachment of the body temperature regulating device to the fabric of clothing and improves the ease of use of the body temperature regulating clothing, and body temperature regulating clothing constructed with this structure.

In one aspect of the present disclosure, which has been made to solve the above problems, a body temperature regulating device capable of regulating the body temperature by a temperature regulation unit according to the present disclosure can be attached and detached to an insertion hole formed in the fabric of the garment, and the body temperature regulating device comprises a main body having an intake section formed with an air hole for taking in air, a flange protruding outward on the outer circumferential surface of the main body, a plurality of guide rails extending in an arc shape along the outer circumferential surface of the main body between one end and the other end on the outer circumferential surface of the main body, and an annular fixing member having a plurality of protrusions connectable to the plurality of guide rails, and each of the plurality of guide rails has a plurality of regulating sections for regulating the movement of the protrusions, the plurality of regulating sections being disposed between the one end and the front end. The plurality of regulating portions are provided intermittently on a sliding surface connecting the flange and the other end, and the plurality of regulating portions include a first regulating portion and a second regulating portion provided on the other end side of the first regulating portion, and a plurality of gaps extending in the axial direction of the main body portion are provided between the plurality of guide rails, and the body temperature regulating device is attached to the fabric by inserting each of the plurality of protrusions into each of the plurality of gaps in the axial direction of the main body portion to sandwich the fabric between the flange and the fixing member, and rotating the flange and the fixing member relatively to each other, so that with the fabric sandwiched between the flange and the fixing member, each of the plurality of protrusions engages with the first regulating portion or the second regulating portion.

According to this aspect, when a person attaches the body temperature regulating device to the fabric of the clothing, each of the projections of the plurality of projections enters the axial direction of the main body into each of the intervals of the plurality of gaps, and the fabric is first sandwiched between the flange and the fixing member. Next, the person rotates the main body and the fixing member relative to each other, and in a state in which the flange and the fixing member sandwich the fabric, each of the projections of the fixing member overcomes each of the plurality of regulating parts, and the movement is regulated by the regulating parts and the regulating parts and the projections engage with each other. This allows the person to attach the body temperature regulating device to the fabric of the clothing with a one-touch operation that gives a sense of moderation. Therefore, since there is no insufficient tightening or loosening of the fixing member, it is possible to prevent the body temperature regulating device from falling off the clothing or the fixing member from being lost. Therefore, a clothing attachment structure for a body temperature regulating device that can easily attach the body temperature regulating device to the fabric of the clothing and improve the ease of use of the body temperature regulating clothing, and a body temperature regulating clothing constructed with this structure are provided.

In addition, the clothing referred to in this disclosure is a general term that includes each of the concepts (a), (b), and (c), which can be broadly categorized as outerwear such as jackets, jumpers, suits, vests, etc., (b) underwear such as pants, trousers, etc., and (c) socks worn on the feet or legs such as socks, foot warmers, etc.

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

In the technology of Patent Document 1, depending on the thickness of the fabric of the air-conditioning garment, the main body side and the pressing member side cannot be firmly screwed together, and the body temperature adjustment device falls off the body temperature adjustment garment. In the technology of Patent Document 1, the flange and the pressing member are screwed together many times to fix the fabric, which causes plastic deformation and thinning of the fabric around the opening of the fabric, and even if the main body side and the pressing member side are screwed together to fix the fabric, the fabric may become loose or damaged. However, according to this aspect, when the fabric of the garment is thick, the flange and the fixing member sandwich the fabric, and each of the protrusions constituting the multiple protrusions engages with the first restricting portion. On the other hand, when the fabric of the garment is not thick, the flange and the fixing member sandwich the fabric, and each of the protrusions constituting the multiple protrusions engages with the second restricting portion. This allows the body temperature adjustment device to be attached in a state where the fabric is firmly sandwiched between the flange and the fixing member so that the body temperature adjustment device does not fall off the body temperature adjustment garment regardless of the thickness of the fabric of the garment. Furthermore, even if each of the multiple protrusions engages with the first regulating portion or the second regulating portion when the fabric covering the flange and the fixing member are sandwiched between them, the fabric around the insertion hole is less likely to undergo plastic deformation, thereby preventing rattling or damage.

In the above aspect, it is preferable that the sliding surfaces provided on each of the plurality of guide rails have a predetermined angle toward the intake portion with respect to a plane parallel to the axial direction of the main body portion.

According to this aspect, even if the main body and the fixing member are rotated relative to each other, the multiple protrusions slide on the sliding surface that has a predetermined angle toward the intake part. This makes it possible to prevent the fabric around the insertion hole from being damaged even if the multiple protrusions slide on the sliding surface, without interfering with the intake of air from the air hole due to the fabric sandwiched between the flange and the fixing member.

In the above aspect, it is preferable that the temperature adjustment unit is a Peltier element, the body temperature adjustment device has a cooling surface and a heat exchange surface opposite the cooling surface, and is configured so that the cold presented to the cooling surface, which has absorbed heat, can be transferred to the body by the Peltier element when it is energized.

According to this aspect, when the temperature regulating garment is worn, the cooling surface that has absorbed heat due to the energized Peltier element is brought into contact with the wearer's body surface directly or indirectly via underwear, etc., thereby efficiently cooling only specific parts of the wearer's body surface that are desired by the wearer, such as areas that feel particularly hot or areas that are particularly sweaty.

In the above aspect, it is preferable that the garment is provided with a discharge section that discharges the air taken in through the air hole, the heat exchange surface has a plurality of cooling fins, the intake section has the air holes formed on the circumference, the cooling surface and the intake section are attached to the body side of the garment, and the flange has an inclined surface on the discharge section side at an angle of 15 degrees to 30 degrees with respect to a plane parallel to the cooling surface.

According to this aspect, the multiple cooling fins on the heat exchange surface are cooled by air taken in through the air holes of the intake section. The air taken in through the air holes of the intake section is guided to the base of the multiple cooling fins by the flange having an inclined surface on the discharge section side at an angle of 15 degrees to 30 degrees with respect to a surface parallel to the cooling surface. In other words, the cooling fins can significantly increase the area for heat exchange, and further, by having an inclined surface on the flange at an angle of 15 degrees to 30 degrees, a portion of the air flowing into the air holes for cooling hits the flange and flows downward. As a result, by changing the flow of air flowing in below the flange to the base side of the cooling fin, the entire cooling air reaches the center of the cooling fin when viewed in a plan view, so that the cooling efficiency can be increased by about 10% compared to when the flange is parallel. By increasing the cooling efficiency by about 10%, for example, in a configuration in which air is discharged from the discharge section by rotating a fan using a motor, the power consumption of the motor can be reduced by about 10%, and the effective cooling time of the temperature control device can be extended from 120 minutes to 132 minutes, for example. Therefore, by increasing the cooling efficiency of the temperature control device while suppressing the power consumption of the temperature control device, the risk of heat stroke for workers working outdoors in extreme heat can be avoided.

In the above aspect, it is preferable that the temperature adjustment unit is a fan, and the body temperature adjustment device is configured to be able to blow either cold air, which is at a lower temperature than the outside air, or warm air, which is at a higher temperature than the outside air, onto the body by rotating the fan.

According to this embodiment, for example, cool air (wind) can be supplied to workers working outdoors in extreme heat, workers working in humid indoor environments, and people engaged in recreation, sports, or watching events under the blazing sun, thereby preventing the onset of heat stroke. Conversely, when used in conjunction with a heat source, such as a hand warmer or simple heater, the outside air supplied to the body temperature regulating device can be blown toward the heat source, and the warm air (wind) heated by the heat source can be blown toward the body, thereby warming up the chilled body.

It is preferable that the body temperature regulating garment is configured so that the body temperature regulating device, which constitutes the clothing attachment structure of the body temperature regulating device of the above-mentioned aspect, is removably attached to the clothing.

According to this aspect, the body temperature regulating device according to the present disclosure can be easily attached by inserting it into an insertion hole in the fabric constituting the body temperature regulating garment, employing the garment attachment structure, and the wearer can be provided with easy-to-use body temperature regulating garment that can accommodate the body temperature regulating device in accordance with any thickness of fabric.

Therefore, according to the present disclosure, it is possible to easily attach a body temperature regulating device to the fabric of clothing, and it is possible to improve the ease of use of the body temperature regulating clothing, which is an excellent effect.

Fig. 3 is a front view of the inside of the temperature regulating vest according to the first embodiment as seen from the front body side when the air blowing unit and the Peltier element unit are not attached. Fig. 4 is a front view of the inside of the temperature regulating vest shown in Fig. 1 as seen from the front body side. Note that the body temperature regulating garment according to the present disclosure is referred to as a temperature regulating vest 1 in this embodiment.

As shown in Figures 1 to 4, the temperature regulating vest 1 comprises a vest body 2, an air blowing unit 40, a Peltier element unit 60, an air blowing operation unit 80, a temperature regulation operation unit 90, a portable battery 84, etc. In the first to third embodiments, there is one air blowing unit 40 and one air blowing operation unit 80, as an example.

<About the vest 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 (work clothes without cuffs) having a front body 4 and a back body 5. However, this body temperature regulating garment may also be work clothes with long sleeves, short sleeves, etc.

In the vest body 2, the fabric 3 is formed into a vest shape by the front fabric 3A and the back fabric 3B. Both the front fabric 3A and the back fabric 3B are made of synthetic resin fibers with excellent heat resistance, strength resistance, and transpiration properties, such as nylon and polyester. However, this is not limited to this, and both the front fabric 3A and the back fabric 3B may be made of leather. The vest body 2 has a collar part 9 at the top that forms a neckline where the wearer's neck is located when worn. At the left and right positions of the vest body 2, there are armhole parts 10 (10A, 10B) through which the wearer's arms pass when worn. The first armhole part 10A is the armhole part through which the wearer's left arm passes when worn. The second armhole part 10B is the armhole part through which the wearer's right arm passes when worn.

As shown in Figure 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 are, for example, pockets. 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 control 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.

1 to 4, the first storage section 6 is provided with a storage opening 8, which is an opening between the outer fabric 3A and the lining of the front body 4 of the vest body 2, to allow the air supply wiring 85 and the temperature control wiring 95 to be inserted therethrough. This allows the air supply wiring 85 and the temperature control wiring 95 to be exposed to the inside of the temperature control vest 1 through the storage opening 8, even when they are stored in the first storage section 6 with one end of them on the portable battery 84 side.

When the fastener (not shown) on the front body 4 of the temperature regulating vest 1 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 piece of lining 11 is sewn to the back fabric 3B.

As shown in FIG. 2, the fan mounting portion 20 to which the air blowing unit 40 can be attached is disposed near the waist region 12 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.

As shown in FIG. 2, the fan mounting part 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 fan mounting part 20 may be made of a fabric such as rubber or resin. As a result, a portion of the air sent in with the rotation of the fan 42 by the blower unit 40 is guided toward the Peltier element unit 60 attached to the fan mounting part 20. The fan mounting part 20 is sewn onto the back fabric 3B.

3, element mounting sections 30 to which Peltier element units 60 can be attached are provided at multiple locations on the lining 11, and in this embodiment, are provided at three locations on the back body 5. On the back body 5, the element mounting sections 30 are located at one location at the neck portion 18, one location near the first armhole portion 10A, and one location near the second armhole portion 10B.

As shown in Figure 3, the element mounting portion 30 has an element insertion hole 32 formed in the element mounting portion 30, and an element outer peripheral edge portion 31 around this element insertion hole 32. As shown in Figures 3 and 4, the element mounting 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 element mounting portion 30 may also be made of a fabric such as rubber or resin. The element mounting portion 30 is sewn onto the lining 11.

<Regarding the Blower Unit 40 of the First Embodiment>
Next, the air blowing unit 40 will be described with reference to Figures 5 to 9. Figure 5 is a front view showing the main body of the air blowing unit shown in Figure 2, and Figure 6 is a rear view of the main body of the air blowing unit shown in Figure 2. Figure 7 is an explanatory diagram showing the air blowing unit according to the first embodiment in a disassembled state into a main body and a pressing member. Figure 8 is an explanatory diagram showing a method of attaching the air blowing unit according to the first embodiment to a temperature regulating vest. Figure 9 is a partial cross-sectional view of the air blowing unit attached to the temperature regulating vest according to the first embodiment.

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

The air blowing 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 blowing 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 in 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.

As shown in Figures 1 to 4, the air blowing unit 40 is electrically connected to the portable battery 84 via the air blowing operation unit 80 by 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 fan 42 rotates. As a result, the wind generated by the rotation of the fan 42 is blown towards the body side towards the body surface BS side (body side) of the wearer HM (see Figure 9).

As shown in Figs. 5 to 7, the casing 44 is composed of an outer case part 46 and an inner case part 45. The outer case part 46 is covered across the fan 42 in the radial direction RD on the lower side Lw where air is blown by the rotation of the fan 42 in the axial direction L along the axial line AX of the fan 42. The outer case part 46 has a plurality of air holes 46a for taking in either cold air that is at a lower temperature than the outside air or hot air that is at a higher temperature than the outside air. The inner case part 45 covers the blower unit drive part 43 on the Lw side in a state where it is connected to the blower unit drive part 43. The inner case part 45 has a plurality of outlets 45a for sending air from outside the blower unit 40. In the casing 44 according to the first embodiment, the inner case part 45 is provided in a cylindrical inner case peripheral wall part 49 that covers the outer circumferential side of the fan 42 and the outer circumferential side of a part of the blower unit drive part 43 on the Lw side. A male thread 48 is formed on the outer periphery of the inner case peripheral wall portion 49 .

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

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, which can be positioned opposite the flange 47. A female screw 112 that can be screwed with the male screw 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, and when the male screw 48 of the inner case peripheral wall portion 49 of the main body portion 41 is screwed with the female screw 112 of the pressing member 110, the pressing member 110 is firmly gripped by these protrusions and easily rotates. Here, screwing means fitting together screws (see Patent Technical Glossary (Nikkan Kogyo Shimbun)). Here, a screw is something that has a spiral groove or protrusion for fastening something (Kojirin 6th Edition). In other words, screwing means fitting together opposing spiral screws or the like to fasten something.

<Installation of the blower unit 40 of the first embodiment>
In mounting the blower unit 40 according to the first embodiment, as shown in Fig. 8, first, the lower side Lw of the main body 41 is inserted into the fan insertion hole 22 formed in the fan mounting part 20 and the insertion hole 3b of the back fabric 3B from the outside 20a of the fan mounting part 20. With the flange 47 in contact with the fan outer peripheral edge 21 of the fan mounting part 20, the outer case part 46 is placed in the fan insertion hole 22 and the insertion hole 3b of the back fabric 3B. Next, a person places the pressing member 110 near the fan outer peripheral edge 21 from the lining 11 side of the temperature control vest 1, and assembles the main body 41 and the pressing member 110 by rotating them relatively. Then, a person fixes the male screw 48 of the main body 41 and the female screw 112 of the pressing member 110 by screwing them together, thereby sandwiching the fan outer peripheral edge 21 and the back fabric 3B between the flange 47 and the pressing part 111. The main body 41 and the pressing member 110 are fixed to the fabric 3 with the fan outer peripheral edge 21 and the back fabric 3B sandwiched between the flange 47 and the pressing portion 111. In this way, the blower unit 40 is fixed to the fabric 3, as shown in Figures 1, 2, 4, and 9.

The portable battery 84 and the airflow wiring 85 can be freely attached and detached by connection via a connector, such as a USB (Universal Serial Bus) connection. Power from the portable battery 84 is supplied to the airflow unit drive unit 43 and the motor of the airflow unit drive unit 43 through the airflow wiring 85.

When a voltage of 5V is supplied through the airflow wiring 85, the drive unit 33 is driven under the control of the airflow control unit 81, and the propeller-type fan 42 is rotated. As the propeller-type fan 42 rotates, air outside the temperature regulating vest 1 is taken in from the back of the airflow unit 40 main body shown in Figure 6, and the air is blown out from the front of the airflow unit 40 main body shown in Figure 5. As shown in Figures 1 to 4, the airflow unit 40 is electrically connected to the portable battery 84 via the airflow operation unit 80 by the airflow wiring 85.

<Regarding the Peltier element unit 60 of the first embodiment>
Next, the Peltier element unit 60 will be described with reference to Figs. 10 to 13. Fig. 10 is an explanatory diagram showing the Peltier element unit from the heat emission surface side in the temperature regulating vest according to the first embodiment. Fig. 11 is an explanatory diagram showing the Peltier element unit from the heat dissipation surface side in the temperature regulating vest 1 according to the first embodiment. Fig. 12 is an exploded perspective view showing the configuration of the Peltier element unit according to the first embodiment. Fig. 13 is an exploded view showing the outer circumferential surface of the main body part according to the first embodiment laid out on a plane.

As shown in Figs. 10 and 11, the Peltier element unit 60 has a Peltier element PE built into the cover member. The Peltier element is a type of plate-shaped semiconductor thermoelectric element. When a direct current is supplied to the Peltier element PE, one side of the flat plate portion of the Peltier element PE absorbs heat to about 10°C due to the Peltier effect, becoming an absorbing state (cooling surface), while the other side on the opposite side simultaneously heats up to about 30°C and becomes a heating state (heating surface). The Peltier element is an element that transfers heat from the cooling surface to the heating surface, generating a large amount of heat on the heating surface side. The Peltier element unit 60 is configured to be able to transfer to the body either the cold heat presented on the cooling surface that has absorbed heat due to the Peltier element PE when it is energized, or the warm heat presented on the heating surface that has absorbed heat and generated heat at the same time on the opposite side of the cooling surface.

As shown in Figs. 10 to 12, the Peltier element unit 60 has a heat dissipation surface 61, which is one surface of the Peltier element unit 60, a cylindrical main body 62, and an air cylinder 64 having an air hole 64a for allowing air to flow in from the temperature control vest 1. The air cylinder 64 has four air holes 64a formed on its circumference. As shown in Figs. 10 to 11, the main body 62 has an emission surface 62a. The Peltier element unit 60 also has a heat exchange surface 65 that takes in heat from the Peltier element PE and dissipates it into the air to exchange heat. The emission surface 62a has an emission section 62b that emits the air that has been heat exchanged by the heat exchange surface 65 to the outside of the Peltier element unit 60. Furthermore, the Peltier element unit 60 also has an air blower 100 that blows the air that has been heat exchanged by the heat exchange surface 65 to the emission section 62b, an inner flange 63 formed on the cover member of the main body 62, a ring fastener 120, and the like.

As shown in FIG. 12, a guide rail 66 is provided on the outer circumferential surface of the main body 62. The guide rail 66 extends toward the release section 62b and between one end 66a and the other end 66b in an arc shape along the circumferential direction CR of the main body 62 (see FIG. 13 and FIG. 15). A plurality of guide rails 66 (e.g., four) are provided at different positions in the circumferential direction CR of the main body 62. A mounting groove portion 69 is provided between each of the plurality of guide rails 66 and the inner flange 63. The plurality of mounting groove portions 69 (e.g., four) are provided along the circumferential direction CR of the main body 62. The guide rails 66 adjacent to each other in the circumferential direction CR are disposed at the same height in the axial direction L (see FIG. 15 to FIG. 17). The four guide rails 66 each have a gap 70 between adjacent guide rails 66. A plurality of (for example, four) gaps 70 are provided on the outer circumferential surface of the main body 62. As shown in FIG.

As shown in FIG. 13, the guide rails 66 each have a sliding surface 68 that connects between one end 66a and the other end 66b of the guide rail 66 and contacts each protrusion 122 of the ring fastener 120. As shown in FIG. 12 and FIG. 13, a plurality of (e.g., four) regulating portions 67 are arranged on each of the sliding surfaces 68 of the guide rails 66. Each of the plurality of regulating portions 67 regulates the movement of the plurality of protrusions 122 that move along the sliding surface 68 toward the anti-circumferential direction ACR of the main body 62. The regulating portions 67 are intermittently arranged on the sliding surface 68 connecting the one end 66a and the other end 66b of each guide rail 66 in the order of the first regulating portion 67a ⇒ the second regulating portion 67b ⇒ the third regulating portion 67c ⇒ the fourth regulating portion 67d. Each of the plurality of fourth regulating portions 67d is configured to a height that each of the plurality of protrusions 122 cannot overcome.

Next, the multiple guide rails 66 provided on the outer peripheral surface of the main body 62 developed on a plane will be described with reference to FIG. 13. As shown in FIG. 13, the multiple guide rails 66 are inclined toward the air cylinder 64 having the air hole 64a with respect to a plane parallel to the axial direction L along the axial line AX of the main body 62. All of the multiple guide rails 66 in the first embodiment have an inclination angle θ of 3° between one end 66a and the other end 66b, which is an example. 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. That is, the inclination angle θ of the sliding surface 68 according to the first embodiment is 3° toward the air cylinder 64 having the air hole 64a with respect to a plane parallel to the axial direction L along the axial line AX of the main body 62.

The ring fastener 120 is formed so that it can be freely fastened to or released from the main body 62, which is the end opposite the heat dissipation surface 61 (cooling surface 61A, heating surface 61B). The ring fastener 120 is made of synthetic resin and has an annular outer flange 121 formed in a substantially polygonal shape. As shown in FIG. 12, the outer flange 121 has twelve elliptical through holes. The inner diameter of the ring fastener 120 is larger than the outer diameter of the emission surface 62a and smaller than the outer diameter of the inner flange 63.

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

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

The heat exchange surface 65 formed on the back side of the heat dissipation surface 61 is made of a metal with excellent thermal conductivity, such as aluminum or copper. The heat exchange surface 65 has a plurality of cooling fins 65a (for example, 117) configured in a protruding shape. Since the cooling fins 65a are configured in a protruding shape, the surface area of the cooling fins 65a is expanded, thereby expanding the area in contact with the air, and it becomes possible to efficiently release the heat of the Peltier element. On the heat exchange surface 65, the cooling fins 65a are aligned at a certain interval so that the air flowing in from the air hole 64a can pass between the cooling fins 65a and the cooling fins 65a. As a result, the cooling air flowing in between the cooling fins 65a and the cooling fins 65a comes into contact with the cooling fins 65a, so that the heat of the Peltier element PE can be efficiently exchanged.

12, a heat dissipation surface 61 (cooling surface 61A, heating surface 61B) is provided at the end opposite to the main body 62 in the axial direction L along the axial line AX of the main body 62. The main body 62 is formed in a cylindrical shape, and is provided with an inner flange 63 that protrudes in the shape of a circular ring from the outer peripheral end.

12, the blower device 100 of the first embodiment includes a heat exhaust fan 101 that blows air, and a heat exhaust fan drive unit 102 that is controlled by a motor (not shown) that rotates the heat exhaust fan 101. As a result, the air that has been heat exchanged by the heat exchange surface 65 is discharged from the discharge unit 62b by the wind generated when the heat exhaust fan 101 rotates as a result of the drive of the heat exhaust fan drive unit 102 under the control of the temperature adjustment control unit 91.

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

For example, when three Peltier element units 60 are attached to the temperature control vest 1, the temperature control wiring 95 takes the form of three temperature control branch lines 96A, 96B, and 96C extending from a single temperature control main line 96 that is divided at a temperature control branch section 97. In other words, the number of temperature control branch lines 96A, 96B, and 96C, etc., matches the number of Peltier element units 60.

The temperature control main line 96 of the temperature control wiring 95 is connected to the portable battery 84. For example, the temperature control branch line 66A is connected to the first Peltier element unit 60A. For example, the temperature control branch line 66B is connected to the second Peltier element unit 60B. For example, the temperature control branch line 66C is connected to the third Peltier element unit 60C. However, this is not limited to this. The temperature control branch lines 66A, 66B, 66C may be connected arbitrarily at the discretion of the wearer HM, particularly by simplifying the wiring path, as long as there is a one-to-one connection relationship with the three Peltier element units 60 (the first to third Peltier element units 60A, 60B, 60C).

<Installation of the Peltier element unit 60 according to the first embodiment>
The mounting of the Peltier element unit 60 will be described with reference to Fig. 14. Fig. 14 is an explanatory diagram showing a method of mounting the Peltier element unit according to the first embodiment to a temperature control vest.

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

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 main body 62 into the inside of the ring fastener 120, and 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 element outer peripheral edge 31 are sandwiched between the inner flange 63 of the main body 62 and the outer flange 121 of the ring fastener 120. Next, the person rotates the main body 62 and the ring fastener 120 relatively in the circumferential direction CR of the main body 62, thereby inserting each of the protrusions 122 from one end 66a of the guide rail 66 into the mounting groove portion 69. Furthermore, the person rotates the main body 62 and the ring fastener 120 relatively in the circumferential direction CR of the main body 62, so that each protrusion 122 slides on the sliding surface 68 of each guide rail 66 along the circumferential direction CR of the main body 62. Next, the person rotates the main body 62 and the ring fastener 120 relatively in the circumferential direction CR of the main body 62, so that the multiple protrusions 122 ride over the regulating parts 67 arranged on each of the multiple sliding surfaces 68. When each of the multiple protrusions 122 rides over each of the multiple regulating parts 67, the multiple regulating parts 67 regulate the movement of the multiple protrusions 122 in the anti-circumferential direction ACR of the main body 62. The protrusions 122 that have ride over the regulating parts 67 and stopped moving are fixed by engaging with the regulating parts 67 through surface contact. As a result, the back side fabric 3B and the element outer peripheral edge part 31 are fixed in a state where they are sandwiched between the inner flange 63 and the outer flange 121. Although the multiple protrusions 122 according to the first embodiment and the restricting portion 67 of the guide rail 66 can be connected to each other, they do not come into contact with opposing helical screws, etc. Therefore, the protrusions 122 of the ring fastener 120 and the restricting portion 67 of the guide rail 66 are fixed to each other by engagement, not by screwing.

The first Peltier element unit 60A is attached to the element attachment portion 30 of the neck portion 18. In this case, the heat dissipation surface 61 (cooling surface 61A or heating surface 61B) faces the body side (neck) of the wearer HM of the temperature regulating vest 1 and is in a state where it can be contacted (see Figs. 18 and 22). This allows the heat dissipation surface 61 (cooling surface 61A or heating surface 61B) to come into contact with the body surface of the wearer HM himself/herself, either directly or indirectly via underwear or the like, to cool the wearer's neck.

The Peltier element unit 60 (second Peltier element unit 60B, third Peltier element unit 60C) is attached to the element attachment portion 30 near the armhole portion 10 (first armhole portion 10A, second armhole portion 10B). In this case, the heat dissipation surface 61 (cooling surface 61A or heating surface 61B) faces the body side (near the armpits) of the wearer HM of the temperature regulating vest 1 and is in a state where it can be contacted (see Figures 18 and 22). As a result, the heat dissipation surface 61 (cooling surface 61A or heating surface 61B) can be brought into contact with the body surface of the wearer HM himself/herself directly or indirectly via underwear, etc., to cool the armpits.

<Thickness of material sandwiched between the inner flange 63 and the outer flange 121>
15 to 17, the locations where the protrusions 122 and the sliding surfaces 68 are engaged and fixed according to the thickness of the fabric sandwiched between the inner flange 63 and the outer flange 121 will be described. FIG. 15 is a side view of the Peltier element unit according to the first embodiment, and is an explanatory diagram showing a state in which the inner flange and the outer flange are engaged in a first step. FIG. 16 is a side view of the Peltier element unit according to the first embodiment, and is an explanatory diagram showing a state in which the inner flange and the outer flange are engaged in a second step. FIG. 17 is a side view of the Peltier element unit according to the first embodiment, and is an explanatory diagram showing a state in which the inner flange and the outer flange are engaged in a third step.

15, a case will be described in which each of the multiple protrusions 122 overcomes the first restricting portion 67a of each guide rail 66 and the guide rail 66 and the protrusions 122 engage in the first stage. When the thickness of the fabric of the temperature control vest 1 is X1 (for example, about 3 mm), the fabric is sandwiched between the inner flange 63 and the outer flange 121, and the person inserts the main body 62 into the inside of the ring fastener 120. As a result, each of the multiple protrusions 122 enters each of the multiple gaps 70. Next, when the person rotates the main body 62 and the ring fastener 120 relatively in the circumferential direction CR of the main body 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 main body 62 and the ring fastener 120 relatively in the circumferential direction CR of the main body 62, each of the multiple protrusions 122 slides on the sliding surface 68 of each guide rail 66 along the circumferential direction CR of the main body 62. When the main body 62 and the ring fastener 120 are rotated relatively along the circumferential direction CR of the main body 62, for example, by 15 degrees, each of the multiple protrusions 122 rides over each of the multiple first restricting parts 67a arranged on the sliding surface 68. The movement of each of the protrusions 122 in the anti-circumferential direction ACR is restricted by each of the first restricting parts 67a that have been overcome. In order for each of the multiple protrusions 122 to ride over each of the multiple first restricting parts 67a, the angle at which the main body 62 and the ring fastener 120 rotate relatively along the circumferential direction CR of the main body 62 is not limited to 15 degrees. For example, it is preferable that the angle be any of 15 degrees to 20 degrees.

15, each of the multiple protrusions 122 whose movement in the circumferential direction CR of the main body 62 has stopped in the first stage comes into surface contact with each of the multiple first restricting parts 67a and engages with them to be fixed. In this case, the Peltier element unit 60 can be attached to the temperature control vest 1 with the fabric of the temperature control vest 1 having a thickness of X1 (for example, about 3 mm) sandwiched between the inner flange 63 and the outer flange 121. When removing the Peltier element unit 60, a person rotates the main body 62 and the ring fastener 120 relatively in the anti-circumferential direction ACR of the main body 62 by, for example, 15 degrees, so that each of the multiple protrusions 122 overcomes each of the first restricting parts 67a. This allows the Peltier element unit 60 to be removed from the temperature control vest 1.

Next, with reference to FIG. 16, a case will be described in which each of the multiple protrusions 122 overcomes the second restricting portion 67b of each guide rail 66 and the guide rail 66 and the protrusions 122 engage in the second stage. When the thickness of the fabric of the temperature regulating vest 1 is X2 (for example, about 2 mm), the fabric is sandwiched between the inner flange 63 and the outer flange 121, and the person inserts the main body 62 into the inside of the ring fastener 120. As a result, each protrusion 122 enters each gap 70. Next, when the person rotates the main body 62 and the ring fastener 120 relatively in the circumferential direction CR of the main body 62, each protrusion 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 main body 62 and the ring fastener 120 relatively in the circumferential direction CR of the main body 62, each of the multiple protrusions 122 slides on the sliding surface 68 of each guide rail 66 along the circumferential direction CR of the main body 62. When the main body 62 and the ring fastener 120 are relatively rotated, for example, by 15 degrees along the circumferential direction CR of the main body 62, each of the multiple protrusions 122 climbs over each of the multiple first restricting portions 67a disposed on the sliding surface 68. The movement of each of the protrusions 122 in the anti-circumferential direction ACR is restricted by each of the first restricting portions 67a that have climbed over.

Furthermore, when a person rotates the main body 62 and the ring fastener 120 relatively along the circumferential direction CR of the main body 62, for example by 15 degrees, each of the multiple protrusions 122 slides on the sliding surface 68 and overcomes each of the multiple second restricting parts 67b. The movement of each of the protrusions 122 in the anti-circumferential direction ACR is restricted by each of the multiple second restricting parts 67b that have been overcome. In order for each of the multiple protrusions 122 to overcome each of the multiple second restricting parts 67b, the angle at which the main body 62 and the ring fastener 120 are rotated relatively along the circumferential direction CR of the main body 62 is not limited to 15 degrees. For example, it is preferable that the angle be anywhere between 15 degrees and 20 degrees.

16, each of the multiple protrusions 122 whose movement in the circumferential direction CR of the main body 62 has stopped in the second stage comes into surface contact with each of the multiple second restricting parts 67b and engages with them to be fixed. In this case, the Peltier element unit 60 can be attached to the temperature control vest 1 with the fabric of the temperature control vest 1 having a thickness of X2 (for example, about 2 mm) sandwiched between the inner flange 63 and the outer flange 121. When removing the Peltier element unit 60, a person rotates the main body 62 and the ring fastener 120 relatively in the anti-circumferential direction ACR of the main body 62 by, for example, 30 degrees, so that each of the multiple protrusions 122 overcomes each of the first restricting parts 67a and the second restricting parts 67b. This allows the Peltier element unit 60 to be removed from the temperature control vest 1.

Next, with reference to FIG. 17, a case will be described in which each of the multiple protrusions 122 overcomes the third restricting portion 67c of each guide rail 66 and the guide rail 66 and the protrusions 122 engage in the third stage. When the thickness of the fabric of the temperature control vest 1 is X3 (for example, about 1 mm), the fabric is sandwiched between the inner flange 63 and the outer flange 121, and the person inserts the main body 62 into the inside of the ring fastener 120. As a result, each protrusion 122 enters each gap 70. Next, when the person rotates the main body 62 and the ring fastener 120 relatively in the circumferential direction CR of the main body 62, each protrusion 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 main body 62 and the ring fastener 120 relatively in the circumferential direction CR of the main body 62, each of the multiple protrusions 122 slides on the sliding surface 68 of each guide rail 66 along the circumferential direction CR of the main body 62. When the main body 62 and the ring fastener 120 are relatively rotated, for example, by 15 degrees along the circumferential direction CR of the main body 62, each of the multiple protrusions 122 climbs over each of the multiple first restricting portions 67a disposed on the sliding surface 68. The movement of each of the protrusions 122 in the anti-circumferential direction ACR is restricted by each of the first restricting portions 67a that have climbed over.

Furthermore, when a person rotates the main body 62 and the ring fastener 120 relatively along the circumferential direction CR of the main body 62, for example by 15 degrees, each of the multiple protrusions 122 slides on the sliding surface 68 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.

Furthermore, when a person rotates the main body 62 and the ring fastener 120 relatively along the circumferential direction CR of the main body 62, for example by 15 degrees, each of the multiple protrusions 122 slides on the sliding surface 68 and overcomes each of the multiple third restriction parts 67c. The movement of each of the protrusions 122 in the anti-circumferential direction ACR is restricted by each of the multiple third restriction parts 67c that have been overcome. In order for each of the multiple protrusions 122 to overcome each of the multiple third restriction parts 67c, the angle at which the main body 62 and the ring fastener 120 are rotated relatively along the circumferential direction CR of the main body 62 is not limited to 15 degrees. For example, it is preferable that the angle be anywhere between 15 degrees and 20 degrees.

17, each of the multiple protrusions 122, whose movement in the circumferential direction CR of the main body 62 has stopped in the third stage, comes into surface contact with each of the multiple third restricting parts 67c and engages with them to be fixed. In this case, the Peltier element unit 60 can be attached to the temperature control vest 1 with the fabric of the temperature control vest 1 having a thickness of X3 (for example, about 1 mm) sandwiched between the inner flange 63 and the outer flange 121. When removing the Peltier element unit 60, a person rotates the main body 62 and the ring fastener 120 relatively in the anti-circumferential direction ACR of the main body 62 by, for example, 45 degrees, so that each of the multiple protrusions 122 overcomes each of the first restricting parts 67a to the third restricting parts 67c. This allows the Peltier element unit 60 to be removed from the temperature control vest 1.

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

When the Peltier element unit 60 according to the first embodiment is attached to the vest body 2, first, each of the protrusions constituting the multiple (e.g., 4) protrusions 122 is inserted into the multiple (e.g., 4) gaps 70 in the axial direction L along the axial line AX of the main body 62. As a result, the inner flange 63 and the ring fastener 120 sandwich the fabric of the temperature control vest 1. Next, the main body 62 and the ring fastener 120 are rotated relative to each other, and the movement of each of the multiple protrusions 122 is restricted by each of the restriction parts 67 that they have overcome while the fabric of the temperature control vest 1 is sandwiched between the inner flange 63 and the ring fastener 120. Furthermore, by each of the multiple protrusions 122 engaging with each of the restriction parts 67, the Peltier element unit 60 is attached to the temperature control vest 1 while the fabric of the temperature control vest 1 is sandwiched between the inner flange 63 and the ring fastener 120. Therefore, a person can attach the Peltier element unit 60 to the temperature control vest 1 with a one-touch operation. Furthermore, when the main body 62 and the ring fastener 120 are rotated relative to each other, the locations 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 thickness of the fabric of the temperature control vest 1 is about 3 mm, each of the multiple protrusions 122 can engage with each of the multiple first restricting parts 67a, and the Peltier element unit 60 can be attached to the temperature control vest 1. If the thickness of the fabric of the temperature control vest 1 is about 2 mm, each of the multiple protrusions 122 can engage with each of the second restricting parts 67b, and the Peltier element unit 60 can be attached to the temperature control vest 1. If the thickness of the fabric of the temperature control vest 1 is about 1 mm, each of the multiple protrusions 122 can engage with each of the third restricting parts 67c, and the Peltier element unit 60 can be attached to the temperature control vest 1. Therefore, regardless of the thickness of the fabric of the temperature control vest 1, a person can attach the Peltier element unit 60 to the temperature control vest 1 in accordance with that thickness. Therefore, it becomes easy to attach the Peltier element unit 60 according to the first embodiment to the fabric of the temperature control vest 1, and it is possible to improve the ease of use of the temperature control vest 1. Furthermore, even if the back fabric 3B and the element mounting part 30 are repeatedly clamped between the inner flange 63 and the ring fastener 120, it is possible to make the back fabric 3B and the element mounting part 30 less susceptible to plastic deformation. Therefore, even if the Peltier element unit 60 is attached to the temperature control vest 1, it is possible to prevent rattling and damage to the back fabric 3B and the element mounting part 30.

<Flange inclination angle>
The inclination angles of the inner flange 63 and the outer flange 121 will be described with reference to Figs. 18 and 19. Fig. 18 is a partial cross-sectional view of the Peltier element unit attached to the element mounting portion. Fig. 19 is an enlarged cross-sectional view of the inner flange and the outer flange shown in Fig. 18. Figs. 18 and 19 are drawings showing a state in which the Peltier element units 60 (first Peltier element unit 60A, second Peltier element unit 60B, third Peltier element unit 60C) are attached to the element mounting portion 30.

18 and 19, the surface 63a of the inner flange 63 of the Peltier element unit 60 and the surface 121a of the outer flange 121 are in contact, i.e., surface contact, with the element mounting portion 30. The surface contact between the surface 63a of the inner flange 63 and the surface 121a of the outer flange 121 can prevent the Peltier element unit 60 from coming off the element mounting portion 30.

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

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

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

<Flange air flow change function>
The inclination angle θ of the front surface 63a and the back surface 63b of the inner flange 63 of the Peltier element unit 60 of the first embodiment is 20° with respect to the heat dissipation surface 61 (cooling surface 61A or heating surface 61B). As a result, the inner flange 63 of the Peltier element unit 60 has a function of changing the flow of air flowing into the air hole 64a of the Peltier element unit 60 downward. The function of the inner flange 63 of the Peltier element unit 60 of the first embodiment to change the flow of air flowing into the air hole 64a of the Peltier element unit 60 downward will be described with reference to Figures 20 and 21.

Figure 20A is an explanatory diagram showing the flow of air flowing into an air hole of a comparative example. Figure 20B is an explanatory diagram showing the flow of air flowing into an air hole of the first embodiment. Figure 21A is an explanatory diagram showing the speed distribution of air flowing into an air hole of a comparative example. Figure 21B is an explanatory diagram showing the speed distribution of air flowing into an air hole of the first embodiment.

First, the installation of the Peltier element unit 60, which is a comparative example shown in Figures 20A and 21A, will be described. The main body 62 side of the Peltier element unit 60 is inserted from the inside 30a of the element mounting part 30 formed in the element mounting part 30 of the temperature control vest 1. The Peltier element unit 60 is placed in the element insertion hole 32 with the inner flange 131 of the comparative example abutting against the element outer peripheral edge part 31 of the element insertion hole 32. Next, the Peltier element unit 60 of the comparative example is equipped with a ring fastener 140 having an annular outer flange 141 that protrudes in the shape of a circular ring plate, and the outer flange 141 abuts against the inner fabric 3B from the outside of the inner fabric 3B. The ring fastener 140 of the comparative example is inserted into the internal space between the lining 11 and the inner fabric 3B. The outer peripheral edge part 31 of the element is sandwiched between the inner flange 131 of the tube part 130 of the comparative example and the outer flange 141 of the ring fastener 140 of the comparative example. By fastening the male thread 132 of the comparative example tube portion 130 and the female thread 142 of the comparative example ring fastener 140 by screwing, the element mounting portion 30 is sandwiched between the comparative example inner flange 131 and the comparative example outer flange 141. Thus, as shown in Figures 20A and 21A, the comparative example Peltier element unit 60 is attached in a state where it is fastened to the element mounting portion 30 and the back fabric 3B.

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

20A, when the inclination angle θ of the inner flange 131 of the comparative example is 0°, air AR (air AR1, air AR2, air AR3, air AR4), which is a part of the air sent in with the rotation of the fan 42 by the blower unit 40, flows into the air hole 64a. The air AR (air AR1, air AR2, air AR3, air AR4) flows into the air hole 64a without colliding with the inner flange 63, and into the inside of the Peltier element unit 60. The air AR (air AR1, air AR2, air AR3, air AR4) that flows into the inside of the Peltier element unit 60 comes into contact with the multiple cooling fins 65a and the heat exchange surface 65, or does not come into contact with the cooling fins 65a, etc.

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

As shown in Figure 20B, air AR5 flowing toward air hole 64a is compressed downward by air AR4 flowing toward air hole 64a along inner flange 63 with inclination angle θ of 20°. This changes the flow of air AR5 toward the base side of cooling fin 65a.

As shown in Figure 20B, air AR4 that has passed through air hole 64a flows into the interior of the Peltier element unit 60. As shown in Figure 20B, air AR6 that has passed through air hole 64a and flowed into the interior of the Peltier element unit 60 is compressed downward by air AR4 that has flowed into the interior of the Peltier element unit 60. This changes the flow of air AR6 toward the base side of the cooling fin 65a. As shown in Figure 20B, air AR7 that has passed through air hole 64a and flowed into the interior of the Peltier element unit 60 flows directly toward the heat exchange surface 65.

As shown in FIG. 20B, the inner flange 63 of the first embodiment has the function of directing the flow of air AR4 that collides with the inner flange 63 downward, thereby changing the direction of the flow of air AR5 and air AR6 toward the air hole 64a to the base of the cooling fin 65a.

Next, using Figure 21A, we will explain the change in air velocity distribution when the inner flange 131 of the comparative example is parallel to the heat dissipation surface 61 (cooling surface 61A or heating surface 61B).

21A is the velocity distribution of a portion of the air sent in conjunction with the rotation of the fan 42 by the blower unit 40. As shown in FIG. 21A, the apex of the first comparative velocity distribution HP1 near the inner flange 131 of the comparative example faces the cooling fin 65a of the heat exchange surface 65. The first comparative velocity distribution HP1 moves toward the cooling fin 65a of the heat exchange surface 65.

When the air sent by the rotation of the fan 42 by the blower unit 40 moves below the inner flange 63 of the Peltier element unit 60, the speed distribution of a portion of the air is the second comparative speed distribution HP2 shown in Figure 20A. As shown in Figure 21A, the apex of the second comparative speed distribution HP2 near the inner flange 131 of the Peltier element unit 60 of the comparative example faces the cooling fin 65a of the heat exchange surface 65, similar to the first comparative speed distribution HP1. The second comparative speed distribution HP2 moves toward the cooling fin 65a of the heat exchange surface 65.

When the air sent with the rotation of the fan 42 by the blower unit 40 moves into the Peltier element unit 60, the speed distribution of a portion of the air is the third comparative speed distribution HP3 shown in FIG. 21A. As shown in FIG. 21A, the apex of the third comparative speed distribution HP3 that has moved into the Peltier element unit 60 of the comparative example faces the cooling fin 65a of the heat exchange surface 65. When the inner flange 63 of the comparative example is parallel to the heat dissipation surface 61 (cooling surface 61A or heating surface 61B), the flow of air toward the air hole 64a is not changed by the inner flange 131, and it moves toward the cooling fin 65a.

Next, using Figure 21B, we will explain the change in air velocity distribution when the inner flange 63 of the first embodiment is inclined at an inclination angle of 20° relative to the heat dissipation surface 61 (cooling surface 61A or heating surface 61B).

The first inclined velocity distribution ZP1 shown in Fig. 21B is the velocity distribution of a portion of the air sent in association with the rotation of the fan 42 by the blower unit 40 near the inner flange 63 of the first embodiment. As shown in Fig. 21B, the peak of the first inclined velocity distribution ZP1 near the inner flange 63 of the first embodiment faces the cooling fin 65a of the heat exchange surface 65. The first inclined velocity distribution ZP1 moves toward the cooling fin 65a of the heat exchange surface 65.

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

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

A part of the air sent by the rotation of the fan 42 by the blower unit 40 flows along the inner flange 63 with an inclination angle θ of 20° toward the base of the cooling fin 65a of the heat exchange surface 65 (see Fig. 20B and Fig. 21B). As a result, the inner flange 63 of the first embodiment can change the flow of air flowing in below the inner flange 63 to the base side of the cooling fin 65a. Therefore, when the cooling fin 65a is viewed in a plan view, the entire cooled air (e.g., 35°C) contained in the temperature control vest 1 reaches the cooling fin 65a located directly below the blower device 100, which the air flowing in from the air hole 64a of the comparative example could not contact. Therefore, the cooling efficiency of the Peltier element unit 60 of the first embodiment can be increased by about 10% compared to when the inner flange 63 is parallel (see Fig. 20A and Fig. 21A). By increasing the cooling efficiency of the Peltier element unit 60 by approximately 10%, the power consumption of the motor that rotates the heat exhaust fan 101 can be reduced by approximately 10%, and the effective cooling time of the temperature regulated vest 1 can be extended from 120 minutes to 132 minutes, for example.

<Air flow inside the temperature control vest 1>
Next, the flow of air inside the temperature regulating vest 1 will be described with reference to Fig. 22. Fig. 22 is an explanatory diagram for explaining the flow of air sent from the air blowing unit of the temperature regulating vest shown in Fig. 1.

22, a portion of the air AR sent in as the fan 42 by the air blowing unit 40 rotates is guided toward the collar 9 through the central back portion 13 and is released from the collar 9 to the outside of the temperature regulating vest 1. A portion of the air AR sent in as the fan 42 by the air blowing unit 40 rotates is taken into the air hole 64a of the first Peltier element unit 60A through the central back portion 13. In this case, the cooling fin 65a is cooled by the air AR taken in through the air hole 64a, and the air that has undergone heat exchange is released from the release portion 62b.

22, a portion of the air AR sent in as the fan 42 rotates by the air blowing unit 40 is guided toward the first armhole portion 10A and is released from the first armhole portion 10A to the outside of the temperature regulating vest 1. A portion of the air AR sent in as the fan 42 rotates by the air blowing unit 40 is taken in by the air hole 64a of the second Peltier element unit 60B. In this case, the cooling fin 65a is cooled by the air AR taken in from the air hole 64a, and the air that has undergone heat exchange is released from the release portion 62b.

22, a portion of the air AR sent in as the fan 42 rotates by the air blowing unit 40 is guided toward the second armhole portion 10B and is released from the second armhole portion 10B to the outside of the temperature regulating vest 1. A portion of the air AR sent in as the fan 42 rotates by the air blowing unit 40 is taken into the air hole 64a of the third Peltier element unit 60C. In this case, the cooling fin 65a is cooled by the air AR taken in from the air hole 64a, and the air that has undergone heat exchange is released from the release portion 62b.

<About the air blower operation unit>
Fig. 23 is a block diagram showing the configuration of an air blowing operation unit provided in the temperature regulating vest according to the first embodiment. As shown in Fig. 23, the air blowing operation unit 80 has an air blowing control unit 81, an air blowing operation unit 82, an air blowing display unit 83, etc. In the air blowing operation unit 80, the air blowing operation unit 82 and the air blowing display unit 83 are electrically connected to the air blowing control unit 81.

The air blowing operation section 82 is configured in such a manner that a push-down section on the top surface of the air blowing operation unit 80 can be lightly pressed with a finger based on a predetermined operation mode to control the on/off switching operation of the power supply to the motor of the drive section 33. 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 such a manner that it can emit white light.

<About the temperature control unit>
Fig. 24 is a block diagram showing the configuration of a temperature adjustment operation unit provided in a temperature control vest according to an embodiment. As shown in Fig. 24, the temperature adjustment operation unit 90 has a temperature adjustment control unit 91, a temperature adjustment operation unit 92, a temperature adjustment display unit 93, etc. In 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.

The temperature control operation unit 92 is configured in such a manner that it is possible to control the on/off switching operation of the current supply to the Peltier element PE for the first to third Peltier element units 60A, 60B, 60C by pressing a press-down portion on the top surface of the temperature control operation unit 90. Furthermore, the temperature control operation unit 92 is configured in such a manner that it is possible to control the on/off switching operation of the current supply to the motor (not shown) that rotates the heat exhaust fan 101 by pressing a press-down portion on the top surface of the temperature control operation unit 90. The temperature control display unit 93 is a display unit on the top surface of the temperature control operation unit 90, and is configured in such a manner that it can selectively emit light from a plurality of colors.

When the temperature control unit 91 has control to reverse the direction of the direct current supplied from the portable battery 84 to the Peltier element PE, the temperature control operation unit 92 lightly presses the push-down portion on the top surface of the temperature control operation unit 90 based on a predetermined operation mode different from the operation of switching the current on/off. This makes it possible to switch the polarity of the current passing through the first to third Peltier element units 60A, 60B, and 60C.

In the Peltier element unit 60, when the direction of the direct current supplied to the Peltier element PE is reversed, the functions of one side and the other side are reversed. Therefore, when the temperature control unit 91 is configured to be able to reverse the polarity of the current supplied to the Peltier element PE, the heat dissipation surface 61 can be selectively changed by the temperature control unit 91 between the cooling surface 61A cooled by heat absorption and the heating surface 61B heated by heat generation. As a result, the cooling surface 61A and the heating surface 61B are interchangeable on the heat dissipation surface 61. Note that when the temperature control unit 91 does not have the function of switching the direction of the current to the Peltier element PE, the heat dissipation surface 61 is either the cooling surface 61A or the heating surface 61B.

Second Embodiment
The features of the temperature regulating vest 1 of the second embodiment will be described in detail below. Unless otherwise stated, the temperature regulating vest 1 of the first embodiment is also applied to the second embodiment. Of course, the configurations according to the second embodiment may be appropriately combined. The technical features in the first embodiment and the second embodiment described below may be appropriately deleted unless they are described as essential in this specification. In the second embodiment, the temperature regulating unit is a fan, and the body temperature regulating device is an air blowing unit.

In the first embodiment, the blower unit 40 is attached to the temperature-regulating vest 1 in a state in which the flange 47 and the pressing part 111 sandwich the fan outer peripheral edge part 21 and the back side clothing fabric 3B by fastening the male screw 48 of the main body part 41 and the female screw 112 of the pressing member 110 by screwing. In the first embodiment, the Peltier element unit 60 is attached to the temperature-regulating vest 1 in a state in which the inner flange 63 and the outer flange 121 sandwich the element mounting part 30 and the back side clothing fabric 3B by fastening by engaging the regulating part 67 of the guide rail 66 with the protrusion 122 of the ring fastener 120. However, this is not limited to this. In the second embodiment, the Peltier element unit 60 is configured to be attached to the temperature-regulating vest 1 in a state in which the inner flange 63 and the outer flange 121 sandwich the element mounting part 30 and the back side clothing fabric 3B by fastening the male screw of the main body part 62 and the female screw of the ring fastener 120 by screwing. The air blowing unit 40 of the second embodiment is configured to be attached to the temperature regulating vest 1 in a state where the flange 47 and the pressing member 110 sandwich the fan mounting portion 20 and the back fabric 3B by engagement between the regulating portion 54 of the guide rail 50 described later and the protrusion of the pressing member 110.

<Regarding the Blower Unit 40 of the Second Embodiment>
The blower unit 40 of the second embodiment will be described with reference to Figures 25 and 26. Figure 25 is an explanatory diagram showing the blower unit according to the second embodiment disassembled into a main body and a pressing member. Figure 26 is a development view of the inner case peripheral wall according to the second embodiment developed on a plane.

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

Each of the guide rails 50 has a sliding surface 53 between one end 50a and the other end 50b of the guide rail 50. As shown in FIG. 26, each of the sliding surfaces 53 of the guide rails 50 has a plurality of (e.g., 4) regulating portions 54 arranged thereon. Each of the plurality of regulating portions 54 regulates the movement of each of the plurality of protrusions 113 moving along the sliding surface 53 toward the anti-circumferential direction ACR of the main body 41. The sliding surface 53 connecting the one end 50a and the other end 50b of each of the guide rails 50 has the regulating portions 54 arranged intermittently in the order of the first regulating portion 54a ⇒ the second regulating portion 54b ⇒ the third regulating portion 54c ⇒ the fourth regulating portion 54d. Each of the plurality of fourth regulating portions 54d is configured to a height that each of the plurality of protrusions 113 cannot overcome.

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

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

<Installation of the blower unit 40 according to the second embodiment>
Next, the attachment of the air blowing unit 40 according to the second embodiment to the temperature regulating vest 1 will be described with reference to Figures 27 and 28. Figure 27 is an explanatory diagram showing a method of attaching the air blowing unit according to the second embodiment to the temperature regulating vest. Figure 28 is a partial cross-sectional view of the air blowing unit attached to the temperature regulating vest.

When installing the blower unit 40 according to the second embodiment, as shown in Figure 27, first the inner case part 45 of the main body part 41 is inserted into the fan insertion hole 22 formed in the fan mounting part 20 and into the insertion hole 3b of the back fabric 3B from the outside 20a of the fan mounting part 20. With the flange 47 abutting against the outer peripheral edge part 21 of the fan, the outer case part 46 is positioned in the fan insertion hole 22 and into the insertion hole 3b of the back fabric 3B.

Next, the person places the pressing member 110 near the fan outer peripheral edge 21 from the lining 11 side of the temperature control vest 1. Then, the person advances the inner case part 45 into the inside of the pressing member 110, and when the inner case peripheral wall part 49 advances to the inside of the pressing member 110, each of the multiple protrusions 113 advances into each of the multiple gaps 51. As a result, the lining fabric 3B and the fan outer peripheral edge 21 are sandwiched between the flange 47 and the pressing part 111. Next, the person rotates the pressing member 110 relatively in the circumferential direction CR of the main body part 41, so that each of the multiple protrusions 113 of the pressing member 110 slides along the circumferential direction CR of the main body part 41 while contacting the sliding surface 53 of each guide rail 50. Next, the person rotates the main body 41 and the pressing member 110 relatively in the circumferential direction CR of the main body 41, and causes each of the multiple protrusions 113 to overcome each of the multiple regulating parts 54 arranged on the sliding surface 53. The multiple protrusions 113 are restricted from moving in the anti-circumferential direction ACR of the main body 41 by each of the multiple regulating parts 54 that the multiple protrusions 113 have overcome (see FIG. 26). Each of the multiple protrusions 113 that have overcome each of the multiple regulating parts 54 and stopped moving is fixed by engaging with each of the multiple regulating parts 54 through surface contact. Therefore, the back fabric 3B and the fan outer peripheral edge part 21 are fixed in a state where they are sandwiched between the flange 47 and the pressing member 110. Although the multiple protrusions 113 and the regulating parts 54 according to the second embodiment can be connected to each other, they are not provided with mutually opposing helical screws or the like. Therefore, the projection 113 of the pressing member 110 and the regulating portion 54 of the guide rail 50 are fixed to each other by engagement, not by screwing.

<Thickness of Fabric to be Sandwiched Between Flange 47 and Pressing Member 110>
29 to 31, the location where the projection 113 and the sliding surface 53 are engaged and fixed by surface contact depending on the thickness of the fabric sandwiched between the flange 47 and the pressing portion 111 will be described. FIG. 29 is a side view of the blower unit according to the second embodiment, and is an explanatory diagram showing a state where the flange and the pressing portion are engaged in the first stage. FIG. 30 is a side view of the blower unit according to the second embodiment, and is an explanatory diagram showing a state where the flange and the pressing portion are engaged in the second stage. FIG. 31 is a side view of the blower unit according to the second embodiment, and is an explanatory diagram showing a state where the flange and the pressing portion are engaged in the third stage.

29, a case will be described in which each of the multiple protrusions 113 overcomes the first restricting portion 54a of each guide rail 50 and the guide rail 50 and the protrusions 113 engage in the first stage. When the thickness of the fabric of the temperature regulating vest 1 is X4 (e.g., about 3 mm), the fabric is sandwiched between the flange 47 and the pressing portion 111, and the person inserts the main body 41 into the inside of the pressing member 110. As a result, each of the protrusions 113 enters each of the gaps 51. Next, when the person rotates the main body 41 and the pressing member 110 relatively in the circumferential direction CR of the main body 41, each of the multiple protrusions 113 enters the mounting groove portion 52 from one end 50a of the guide rail 50. Next, when the person rotates the main body 41 and the pressing member 110 relatively in the circumferential direction CR of the main body 41, each of the multiple protrusions 113 slides on the sliding surface 53 of each guide rail 50 along the circumferential direction CR of the main body 41. When the person rotates the main body 41 and the pressing member 110 relatively along the circumferential direction CR of the main body 41 by, for example, 15 degrees, each of the multiple protrusions 113 rides over each of the multiple first restricting parts 54a arranged on the sliding surface 53. The movement of each of the protrusions 113 in the anti-circumferential direction ACR is restricted by each of the first restricting parts 67a that have been overcome. In order for each of the multiple protrusions 113 to ride over each of the multiple first restricting parts 54a, the angle at which the main body 41 and the pressing member 110 rotate relatively along the circumferential direction CR of the main body 41 is not limited to 15 degrees. For example, it is preferable that the angle be any one of 15 degrees to 20 degrees.

29, the multiple protrusions 113, whose movement in the circumferential direction CR of the main body 41 has stopped in the first stage, are fixed by surface contact with each of the multiple first restricting parts 54a on the sliding surface 53. In this case, the air blowing unit 40 can be attached to the temperature regulating vest 1 with the fabric of the temperature regulating vest 1 having a thickness of X4 (for example, about 3 mm) sandwiched between the flange 47 and the pressing member 110. When removing the air blowing unit 40 from the temperature regulating vest 1, a person rotates the main body 41 and the pressing member 110 relatively in the counter-circumferential direction ACR of the main body 41, for example, by 15 degrees, so that each of the multiple protrusions 113 overcomes each of the first restricting parts 54a. This allows the air blowing unit 40 to be removed from the temperature regulating vest 1.

Next, with reference to FIG. 30, a case will be described in which each of the multiple protrusions 113 overcomes the first restricting portion 54a of each guide rail 50, and the guide rail 50 and the protrusions 113 engage in the second stage. When the thickness of the fabric of the temperature regulating vest 1 is X5 (for example, about 2 mm), the fabric is sandwiched between the flange 47 and the pressing portion 111, and the person causes the main body portion 41 to enter the inside of the pressing member 110. As a result, each of the protrusions 113 enters each of the gaps 51. Next, when the person rotates the main body portion 41 and the pressing member 110 relatively in the circumferential direction CR of the main body portion 41, each of the multiple protrusions 113 enters the mounting groove portion 52 from one end 50a of the guide rail 50. Next, when the person rotates the main body 41 and the pressing member 110 relatively in the circumferential direction CR of the main body 41, each of the multiple protrusions 113 slides on the sliding surface 53 of each guide rail 50 along the circumferential direction CR of the main body 41. When the person rotates the main body 41 and the pressing member 110 relatively by, for example, 15 degrees along the circumferential direction CR of the main body 41, the multiple protrusions 113 climb over each of the multiple first restricting portions 54a disposed on the sliding surface 53. The movement of each protrusion 113 in the anti-circumferential direction ACR is restricted by each of the first restricting portions 67a that have climbed over.

Furthermore, when a person rotates the main body 41 and the pressing member 110 relatively along the circumferential direction CR of the main body 41, for example by 15 degrees, each of the multiple protrusions 113 slides on the sliding surface 53 and overcomes each of the multiple second restricting parts 54b. The movement of each of the protrusions 113 in the anti-circumferential direction ACR is restricted by each of the multiple second restricting parts 54b that have been overcome. In order for each of the multiple protrusions 113 to overcome each of the multiple second restricting parts 54b, the angle at which the main body 41 and the pressing member 110 rotate relatively along the circumferential direction CR of the main body 41 is not limited to 15 degrees. For example, it is preferable that the angle be anywhere between 15 degrees and 20 degrees.

30, the multiple protrusions 113, whose movement in the circumferential direction CR of the main body 41 has stopped in the second stage, are fixed by surface contact with each of the multiple second restricting parts 54b on the sliding surface 53. In this case, the air blowing unit 40 can be attached to the temperature regulating vest 1 with the fabric of the temperature regulating vest 1 having a thickness of X5 (for example, about 2 mm) sandwiched between the flange 47 and the pressing member 110. When removing the air blowing unit 40, a person rotates the main body 41 and the pressing member 110 relatively in the counter-circumferential direction ACR of the main body 41, for example, by 30 degrees, so that each of the multiple protrusions 113 overcomes each of the first restricting parts 54a and the second restricting parts 54b. This allows the air blowing unit 40 to be removed from the temperature regulating vest 1.

Next, with reference to FIG. 31, a case will be described in which each of the multiple protrusions 113 overcomes the first restricting portion 54a of each guide rail 50 in the third stage, and the guide rail 50 and the protrusions 113 engage. When the thickness of the fabric of the temperature regulating vest 1 is X6 (for example, about 1 mm), the fabric is sandwiched between the flange 47 and the pressing portion 111, and the person causes the main body portion 41 to enter the inside of the pressing member 110. As a result, each of the protrusions 113 enters each of the gaps 51. Next, when the person rotates the main body portion 41 and the pressing member 110 relatively in the circumferential direction CR of the main body portion 41, each of the multiple protrusions 113 enters the mounting groove portion 52 from one end 50a of the guide rail 50. Next, when the person rotates the main body 41 and the pressing member 110 relatively in the circumferential direction CR of the main body 41, each of the multiple protrusions 113 slides on the sliding surface 53 of each guide rail 50 along the circumferential direction CR of the main body 41. When the person rotates the main body 41 and the pressing member 110 relatively by, for example, 15 degrees along the circumferential direction CR of the main body 41, each of the multiple protrusions 113 climbs over each of the multiple first restricting portions 54a disposed on the sliding surface 53. The movement of each of the protrusions 113 in the anti-circumferential direction ACR is restricted by each of the first restricting portions 67a that have climbed over.

Furthermore, when a person rotates the main body 41 and the pressing member 110 relatively along the circumferential direction CR of the main body 41, for example by 15 degrees, each of the multiple protrusions 113 slides on the sliding surface 53 and climbs over each of the multiple second restriction parts 54b. The movement of each protrusion 113 in the anti-circumferential direction ACR is restricted by each of the second restriction parts 54b that it has climbed over.

Furthermore, when a person rotates the main body 41 and the pressing member 110 relatively along the circumferential direction CR of the main body 41, for example by 15 degrees, each of the multiple protrusions 113 slides on the sliding surface 53 and overcomes each of the multiple third restricting parts 54c. The movement of each of the protrusions 113 in the anti-circumferential direction ACR is restricted by each of the multiple third restricting parts 54c that have been overcome. In order for each of the multiple protrusions 113 to overcome each of the multiple third restricting parts 54c, the angle at which the main body 41 and the pressing member 110 rotate relatively along the circumferential direction CR of the main body 41 is not limited to 15 degrees. For example, it is preferable that the angle be anywhere between 15 degrees and 20 degrees.

31, the multiple protrusions 113, whose movement in the circumferential direction CR of the main body 41 has stopped in the third stage, come into surface contact with and engage with the multiple third restricting parts 54c on the sliding surface 53, thereby being fixed. In this case, the air blowing unit 40 can be attached to the temperature regulating vest 1 with the fabric of the temperature regulating vest 1 having a thickness of X6 (for example, about 1 mm) sandwiched between the flange 47 and the pressing member 110. When removing the air blowing unit 40, a person rotates the main body 41 and the pressing member 110 relatively in the counter-circumferential direction ACR of the main body 41, for example, by 45 degrees, so that each of the multiple protrusions 113 overcomes each of the first restricting parts 54a to the third restricting parts 54c. This allows the air blowing unit 40 to be removed from the temperature regulating vest 1.

When each of the multiple protrusions 113 overcomes the third restricting portion 54c, even if a person rotates the main body 41 and the pressing member 110 relatively in the circumferential direction CR of the main body 41, each of the multiple protrusions 113 cannot overcome each of the multiple fourth restricting portions 54d. This makes it possible to prevent the air blowing unit 40 from falling off the temperature regulating vest 1 due to the relative rotation of the main body 41 and the pressing member 110 in the circumferential direction of the main body 41.

When the blower unit 40 according to the second embodiment is attached to the vest body 2, first, each of the protrusions constituting the multiple (e.g., 4) protrusions 113 is inserted into the multiple (e.g., 4) gaps 51 in the axial direction L along the axial line AX of the main body 41. As a result, the flange 47 and the pressing member 110 sandwich the fabric of the temperature control vest 1. Next, the main body 41 and the pressing member 110 are rotated relative to each other, and in a state in which the fabric of the temperature control vest 1 is sandwiched between the flange 47 and the pressing member 111, the movement of each of the multiple protrusions 113 is restricted by the restricting portion 54 that they have overcome. Furthermore, each of the multiple protrusions 113 engages with each of the restricting portions 54, and the blower unit 40 is attached to the temperature control vest 1. Therefore, a person can attach the blower unit 40 to the temperature control vest 1 with a one-touch operation. Furthermore, when the main body 41 and the pressing member 110 are rotated relative to each other, the locations at which the plurality of protrusions 113 engage can be changed stepwise. As a result, if the thickness of the fabric of the temperature control vest 1 is about 3 mm, the plurality of protrusions 113 engage with the first restricting portion 54a, and the air blowing unit 40 can be attached to the temperature control vest 1. If the thickness of the fabric of the temperature control vest 1 is about 2 mm, the plurality of protrusions 113 engage with the second restricting portion 54b, and the air blowing unit 40 can be attached to the temperature control vest 1. If the thickness of the fabric of the temperature control vest 1 is about 1 mm, the plurality of protrusions 113 engage with the third restricting portion 54c, and the air blowing unit 40 can be attached to the temperature control vest 1. Therefore, regardless of the thickness of the fabric of the temperature control vest 1, a person can attach the air blowing unit 40 to the temperature control vest 1 in accordance with that thickness. Therefore, it is easy to attach the air blowing unit 40 according to the second embodiment to the fabric of the temperature control vest 1, and the ease of use of the temperature control vest 1 can be improved. Furthermore, even if the lining fabric 3B and the fan mounting part 20 are repeatedly pinched between the flange 47 and the pressing part 111, the lining fabric 3B and the fan mounting part 20 are unlikely to undergo plastic deformation. Therefore, even when the air blowing unit 40 is attached to the temperature regulating vest 1, rattling and damage to the lining fabric 3B and the fan mounting part 20 can be prevented.

Third Embodiment
The features of the temperature regulating vest 1 of the third embodiment will be described in detail below. Unless otherwise stated, the temperature regulating vest 1 of the first embodiment is also applied to the third embodiment. Of course, the configurations according to the third embodiment may be appropriately combined. The technical features in the first embodiment, the second embodiment, and the third embodiment described below may be appropriately deleted unless they are described as essential in this specification.

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

<About the Best Temperature Control>
Fig. 32 is a front view of the outer surface of a temperature regulating vest according to a third embodiment as seen from the front body side, and a back view as seen from the rear body side is shown in Fig. 33. As shown in Figs. 32 and 33, the temperature regulating vest 1 comprises a vest body 2, an air blowing unit 40, a Peltier element unit 60, an air blowing operation unit 80, a temperature regulation operation unit 90, a portable battery 84, etc.

<About the vest body 2>
The vest body 2 according to the third embodiment will be described with reference to Figures 32 and 33. The lining 11 has element attachment parts 30 to which Peltier element units 60 can be attached, which are provided at a plurality of locations, and in this embodiment, are provided at three locations on the back body 5. As shown in Figure 33, on the back body 5, the element attachment parts 30 are provided at one location on the shoulder blade portion 15, one location near the first armhole portion 10A, and one location near the second armhole portion 10B.

<Regarding the Peltier element unit 60 according to the third embodiment>
Next, the Peltier element unit 60 will be described with reference to Figs. 34 to 37. Fig. 34 is a perspective view of the Peltier element unit according to the third embodiment, seen from the heat dissipation surface side. Fig. 35 is a perspective view of the Peltier element unit according to the third embodiment, seen from the emission surface side. Fig. 36 is an exploded perspective view showing the configuration of the Peltier element unit according to the third embodiment. Fig. 37 is a development view of the outer circumferential surface of the cylindrical portion according to the third embodiment, developed on a plane.

34 and 35, the fourth Peltier element unit 60D provided on the scapular part 15 is formed in a substantially polygonal shape (for example, substantially heptagonal). As shown in FIG. 34 and FIG. 35, the fourth Peltier element unit 60D has a main body part 71 in which the Peltier element PE is housed, a cylindrical tube part 75, and a ring fastener 150. As shown in FIG. 34 to FIG. 35, the main body part 71 has a bottom surface 79 having a heat dissipation surface 61 and formed in a substantially polygonal shape (for example, substantially heptagonal), and a top surface 76 having a tube part 75 and formed in a substantially polygonal shape (for example, substantially heptagonal). Furthermore, the main body part 71 also has a side part 72 in which a plurality of intake ports 72a are formed, and a discharge surface 75a forming a discharge part 75b that discharges the air heat-exchanged by the heat exchange surface 65 to the outside of the fourth Peltier element unit 60D. The side portion 72 has five side portions each having five intake ports 72a and two side portions each having ten intake ports 72a. As shown in FIG. 36, the main body portion 71 houses the Peltier element PE and the heat exchange surface 65 that takes in heat from the Peltier element PE and dissipates it into the air to perform heat exchange. Furthermore, as shown in FIG. 36, the main body portion 71 houses the blower device 100 that blows the air that has been heat exchanged by the heat exchange surface 65 to the discharge portion 75b, and the flow guide portion 74 that guides the air sucked from the intake port 72a toward the heat exchange surface 65. The flow guide portion 74 according to the third embodiment is made of synthetic resin fibers that have excellent heat resistance and strength, such as nylon and polyester. The vertical length of the fourth Peltier element unit 60D is 115 mm, the horizontal length is 100 mm, and the height is 30 mm. As shown in FIG. 36, the upper surface 76 is fixed to the main body 71 by six male screws.

It is preferable that the ratio of the total surface area of the 35 intake ports 72a to the total surface area of the seven side portions 72 according to the third embodiment is about 50% to about 69%. This is because, if the ratio of the total surface area of the 35 intake ports 72a exceeds about 69%, the air taken into the main body 71 is affected by the wind outside the fourth Peltier element unit 60D. This is because the air taken in from the intake port 72a is affected by the wind outside the fourth Peltier element unit 60D and cannot be efficiently discharged from the discharge portion 75b. On the other hand, if the ratio of the total surface area of the 35 intake ports 72a is less than about 50%, the amount of cooling air taken in from the intake port 72a is reduced, and efficient heat exchange by the heat exchange surface 65 is not possible.

36, a guide rail 66 is provided on the outer peripheral surface of the tube portion 75. The guide rail 66 extends in an arc shape along the circumferential direction CR of the tube portion 75 toward the discharge portion 75b side. A plurality of guide rails 66 (for example, four) are provided at different positions in the circumferential direction CR of the tube portion 75. As shown in FIG. 36, mounting grooves 78 are provided between the plurality of guide rails 66 and the discharge surface 75a. The plurality of mounting grooves 78 (for example, four) are provided along the circumferential direction CR of the tube portion 75. As shown in FIG. 36, the four guide rails 66 each have a gap 77 between the guide rails 66 that are adjacent to each other in the discontinuous direction. A plurality of gaps 77 (for example, four) are provided on the outer peripheral surface of the tube portion 75. The guide rails 66 adjacent to each other in the circumferential direction CR are disposed at the same height in the axial direction L. As shown in FIG. 36, the gap 77 communicates with a mounting groove 78 .

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

Next, the multiple guide rails 66 on the outer peripheral surface of the tube portion 75 developed on a plane will be described with reference to FIG. 37. As shown in FIG. 37, the multiple guide rails 66 are inclined toward the side portion 72 having the suction port 72a with respect to a plane parallel to the axial direction L along the axial line AX of the main body portion 71. All of the multiple guide rails 66 in the third embodiment have an inclination angle θ of 3° between one end 66a and the other end 66b of the sliding surface 68, which is an example. As a result, all of the multiple guide rails 66 in the third embodiment are formed in an inclined state with a height difference ΔH in the axial direction L between one end 50a and the other end 50b. That is, the inclination angle θ of the sliding surface 68 according to the third embodiment is 3° toward the side portion 72 having the suction port 72a with respect to a plane parallel to the axial direction L along the axial line AX of the main body portion 71.

The ring fastener 150 is formed so that it can be freely fastened to or released from the tubular portion 75, which is the end opposite the heat dissipation surface 61 (cooling surface 61A, heating surface 61B). The ring fastener 150 is made of synthetic resin and has a gripping portion 152 formed in a substantially polygonal shape and an annular outer flange 151. The inner diameter of the ring fastener 150 is larger than the outer diameter of the tubular portion 75, but smaller than the outer periphery of the upper surface 76.

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

The heat dissipation surface 61 is exposed to the outside, and in the Peltier element unit 60 (Peltier element unit), as shown in Figures 34 and 36, the bottom surface 79 having the heat dissipation surface 61 and the emission section 75b are arranged on opposite sides of each other. Here, the heat dissipation surface 61 is made of, for example, aluminum, which is a metal with excellent thermal conductivity. By making the heat dissipation surface 61 of the third embodiment out of aluminum, it can be made three-dimensional rather than flat, and can be made into a shape that fits perfectly with the body surface BS of the wearer HM.

As shown in FIG. 36, a cylindrical portion 75 is provided at the end opposite the heat dissipation surface 61 (cooling surface 61A, heating surface 61B) in the axial direction L along the axial line AX of the main body portion 71.

36, the blower device 100 of the third embodiment includes a heat exhaust fan 101 that blows air, and a heat exhaust fan drive unit 102 that is controlled by a motor (not shown) that rotates the heat exhaust fan 101. As a result, the air that has been heat exchanged by the heat exchange surface 65 is discharged from the discharge unit 75b by the wind generated by the rotation of the heat exhaust fan 101 when the heat exhaust fan drive unit 102 is driven under the control of the temperature adjustment control unit 91.

For example, as shown in FIG. 32, the temperature control branch line 66A according to the third embodiment is connected to the fourth Peltier element unit 60D. For example, the temperature control branch line 66B is connected to the second Peltier element unit 60B. For example, the temperature control branch line 66C is connected to the third Peltier element unit 60C. However, this is not limited to this. The temperature control branch lines 66A, 66B, 66C may be connected arbitrarily at the discretion of the wearer HM, particularly by simplifying the wiring path, as long as there is a one-to-one connection relationship with the three Peltier element units 60 (second to fourth Peltier element units 60B, 60C, 60D).

<Attachment of the Peltier element unit 60 according to the third embodiment>
The mounting of the fourth Peltier element unit 60D will be described with reference to Figs. 38 to 39. Fig. 38 is a cross-sectional view of the fourth Peltier element unit mounted on the temperature regulating vest according to the third embodiment. Fig. 39 is a cross-sectional view taken along line AA in Fig. 35.

A method of mounting the fourth Peltier element unit 60D to the element mounting portion 30 will be described with reference to Figure 38. As shown in Figure 39, when mounting the fourth Peltier element unit 60D, the tubular portion 75 side of the fourth Peltier element unit 60D is inserted into the element insertion hole 32 formed in the element mounting portion 30 of the temperature regulating vest 1 and into the insertion hole 3b of the back fabric 3B from the inside 30a of the element mounting portion 30. The fourth Peltier element unit 60D is placed in the element insertion hole 32 and the insertion hole 3b of the back fabric 3B with the upper surface 76 of the fourth Peltier element unit 60D abutting against the element outer peripheral edge portion 31 of the element insertion hole 32.

Next, the outer flange 151 is brought into contact with the inner fabric 3B from the outside of the inner fabric 3B. The person inserts the tube portion 75 into the inside of the ring fastener 150, and each of the multiple protrusions 153 of the ring fastener 150 into each of the multiple gaps 77. As a result, the inner fabric 3B and the element outer peripheral edge portion 31 are sandwiched between the upper surface 76 of the fourth Peltier element unit 60D and the outer flange 151 of the ring fastener 150. Next, the person rotates the main body portion 71 and the ring fastener 150 relatively in the circumferential direction CR of the tube portion 75, thereby inserting each of the protrusions 133 from one end 66a of the guide rail 66 into the mounting groove portion 69. Then, the person rotates the ring fastener 150 relatively in the circumferential direction CR of the tube portion 75, so that each of the multiple protrusions 153 slides on the sliding surface 68 of each of the guide rails 66 along the circumferential direction CR of the tube portion 75. Furthermore, the person rotates the main body 71 and the ring fastener 150 relatively in the circumferential direction CR of the tube portion 75, so that each of the multiple protrusions 153 rides over each of the multiple regulating parts 67 arranged on the sliding surface 68. When each of the multiple protrusions 153 rides over each of the multiple regulating parts 67, the movement of the multiple regulating parts 67 toward the anti-circumferential direction ACR of the tube portion 75 is regulated by the multiple regulating parts 67 that have been ridden over. Each of the multiple protrusions 153 that has stopped moving comes into surface contact with each of the multiple regulating parts 67 that it has ridden over, thereby being fixed. Therefore, the back fabric 3B and the element outer peripheral edge 31 are fixed in a state of being sandwiched between the outer flange 151 and the upper surface 76 of the main body 71. The protrusion 153 according to the third embodiment and the restricting portion 67 of the guide rail 66 can be connected, but they do not come into contact with opposing helical screws or the like. Therefore, the protrusion 153 of the ring fastener 150 and the restricting portion 67 of the guide rail 66 are fixed by engagement, not by screwing.

The fourth Peltier element unit 60D is attached to the element attachment portion 30 of the scapular portion 15. The surface side of the heat dissipation surface 61 of the fourth Peltier element unit 60D is larger than the surface area of the heat dissipation surface 61 of the second Peltier element unit 60B and the third Peltier element unit 60C. As a result, as shown in FIG. 32 and FIG. 39, the heat dissipation surface 61 (cooling surface 61A or heating surface 61B) is in a state where it can face and contact the body side (scapula) of the wearer HM of the temperature control vest 1. As a result, the heat dissipation surface 61 (cooling surface 61A or heating surface 61B) can be brought into contact with the body surface of the wearer HM himself directly or indirectly via underwear, etc., to cool the area around the shoulder blades of the wearer HM. Furthermore, the cooling surface 61A of the fourth Peltier element unit 60D can cool the body surface of the wearer HM more widely than the cooling surface 61A of the second Peltier element unit 60B or the third Peltier element unit 60C.

As shown in FIG. 39, in the fourth Peltier element unit 60D, the heat exchange surface 65 having a plurality of cooling fins 65a is provided directly below the blower device 100. In the fourth Peltier element unit 60D, a flow guide portion 74 is disposed on the heat exchange surface 65 side of the intake port 72a and in front of the heat exchange surface 65. The height difference from the bottom surface to the top surface of the flow guide portion 74 is configured to be greater than the height difference from the bottom surface of the heat exchange surface 65 to the tip of the cooling fin 65a. This allows a large amount of air sucked in from the intake port 72a to be guided toward the heat exchange surface 65. As shown in FIG. 39, the side portion 72 of the fourth Peltier element unit 60D is formed so as to be directly below one end 76a of the top surface 76 located in the radial direction RD centered on the axial line AX of the main body portion 71, rather than the outer diameter end 151a of the outer flange 151. As shown in Figure 39, the side portion 72 of the fourth Peltier element unit 60D is formed so as to be directly below one end 76b of the upper surface 76 that is located in the radial direction RD centered on the axial line AX of the main body portion 71, and lower than the outer diameter end 151b of the outer flange 151.

<Thickness of material sandwiched between upper surface 76 and outer flange 151>
40 to 42, the location where the projection 153 and the sliding surface 68 are engaged and fixed by surface contact according to the thickness of the fabric of the temperature regulating vest 1 sandwiched between the upper surface 76 and the outer flange 151 will be described. FIG. 40 is a side view of the fourth Peltier element unit according to the third embodiment, and is an explanatory diagram showing a state in which the inner flange and the outer flange are engaged in a first step. FIG. 41 is a side view of the fourth Peltier element unit according to the third embodiment, and is an explanatory diagram showing a state in which the inner flange and the outer flange are engaged in a second step. FIG. 42 is a side view of the fourth Peltier element unit according to the third embodiment, and is an explanatory diagram showing a state in which the inner flange and the outer flange are engaged in a third step.

Using FIG. 40, a case will be described in which each of the multiple protrusions 153 overcomes the first restricting portion 67a of each guide rail 66 and the guide rail 66 and the protrusions 153 engage in the first stage. When the thickness of the fabric of the temperature control vest 1 is X7 (for example, about 3 mm), the fabric is sandwiched between the upper surface 76 of the main body 71 and the surface 154 of the outer flange 151, and the person inserts the tube portion 75 of the main body 71 into the inside of the ring fastener 150. As a result, each protrusion 153 enters each gap 77. Next, when the person rotates the main body 71 and the ring fastener 150 relatively in the circumferential direction CR of the tube portion 75, each protrusion 153 of the ring fastener 150 enters the mounting groove portion 78 from one end 66a of the guide rail 66. Furthermore, when a person rotates the main body 71 and the ring fastener 150 relatively in the circumferential direction CR of the tube part 75, each of the multiple protrusions 153 slides on the sliding surface 68 of each guide rail 66 along the circumferential direction CR of the tube part 75. When the main body 71 and the ring fastener 150 are rotated relatively along the circumferential direction CR of the main body 62 by, for example, 15 degrees, each of the multiple protrusions 153 rides over each of the multiple first restricting parts 67a arranged on the sliding surface 68. The movement of each of the protrusions 153 in the anti-circumferential direction ACR is restricted by each of the first restricting parts 67a that have been overcome. In order for each of the multiple protrusions 153 to ride over each of the multiple first restricting parts 67a, the angle at which the main body 71 and the ring fastener 150 rotate relatively along the circumferential direction CR of the main body 71 is not limited to 15 degrees. For example, it is preferable that the angle be any of 15 degrees to 20 degrees.

40, each of the multiple protrusions 153 whose movement in the circumferential direction CR of the tube part 75 has stopped in the first stage comes into surface contact with each of the multiple first restricting parts 67a and engages with them to be fixed. In this case, the fourth Peltier element unit 60D can be attached to the temperature control vest 1 in a state in which the fabric of the temperature control vest 1 having a thickness of X7 (for example, about 3 mm) is sandwiched between the upper surface 76 of the main body part 71 and the surface 154 of the outer flange 151. When removing the fourth Peltier element unit 60D, a person rotates the main body part 71 and the ring fastener 150 relative to the anti-circumferential direction ACR of the main body part 71, so that each of the multiple protrusions 153 overcomes each of the first restricting parts 67a. This allows the Peltier element unit 60 to be removed from the temperature control vest 1. In this case, the person rotates the main body part 71 and the ring fastener 150 relative to the anti-circumferential direction ACR of the main body part 71 by 15 degrees, for example.

Next, using FIG. 41, a case will be described in which each of the multiple protrusions 153 overcomes the second restricting portion 67b of each guide rail 66 and the guide rail 66 and the protrusions 153 engage in the second stage. When the thickness of the fabric of the temperature control vest 1 is X8 (for example, about 2 mm), the person inserts the tubular portion 75 of the main body portion 71 into the inside of the ring fastener 150 while the fabric is sandwiched between the upper surface 76 of the main body portion 71 and the outer flange 151. As a result, each protrusion 153 enters each gap 77. Next, when the person rotates the main body portion 71 and the ring fastener 150 relatively in the circumferential direction CR of the tubular portion 75, each protrusion 153 of the ring fastener 150 enters the mounting groove portion 78 from one end 66a of the guide rail 66. Furthermore, when a person rotates the main body 71 and the ring fastener 150 relatively in the circumferential direction CR of the tube portion 75, each of the multiple protrusions 153 slides on the sliding surfaces 68 of the respective guide rails 66 along the circumferential direction CR of the tube portion 75. When the main body 71 and the ring fastener 150 are relatively rotated, for example, by 15 degrees along the circumferential direction CR of the main body 62, each of the multiple protrusions 153 climbs over each of the multiple first restricting portions 67a disposed on the sliding surfaces 68. The movement of each of the protrusions 153 in the anti-circumferential direction ACR is restricted by each of the first restricting portions 67a that have climbed over.

Furthermore, when a person rotates the main body 71 and the ring fastener 150 relatively along the circumferential direction CR of the tube portion 75, for example by 15 degrees, each of the multiple protrusions 153 slides on the sliding surface 68 and overcomes each of the multiple second restricting portions 67b. The movement of each of the protrusions 153 in the anti-circumferential direction ACR is restricted by each of the multiple second restricting portions 67b that have been overcome. In order for each of the multiple protrusions 153 to overcome each of the multiple second restricting portions 67b, the angle at which the main body 71 and the ring fastener 150 are rotated relatively along the circumferential direction CR of the main body 71 is not limited to 15 degrees. For example, it is preferable that the angle be anywhere between 15 degrees and 20 degrees.

41, each of the plurality of protrusions 153 whose movement in the circumferential direction CR of the tube portion 75 has stopped in the second stage comes into surface contact with each of the plurality of first restricting portions 67a and engages with them to be fixed. In this case, the fourth Peltier element unit 60D can be attached to the temperature control vest 1 in a state in which the fabric of the temperature control vest 1 having a thickness of X8 (for example, about 2 mm) is sandwiched between the upper surface 76 of the main body portion 71 and the surface 154 of the outer flange 151. When removing the fourth Peltier element unit 60D, a person rotates the main body portion 71 and the ring fastener 150 relative to the counter-circumferential direction ACR of the main body portion 71, so that each of the plurality of protrusions 153 overcomes each of the first restricting portions 67a and the second restricting portions 67b. This allows the Peltier element unit 60 to be removed from the temperature control vest 1. In this case, the person rotates the main body portion 71 and the ring fastener 150 relative to the counter-circumferential direction ACR of the main body portion 71 by, for example, 30 degrees.

Next, using FIG. 42, a case will be described in which each of the multiple protrusions 153 overcomes the third restricting portion 67c of each guide rail 66 and the guide rail 66 and the protrusions 153 engage in the third stage. When the thickness of the fabric of the temperature control vest 1 is X9 (for example, about 1 mm), the fabric is sandwiched between the upper surface 76 of the main body 71 and the outer flange 151, and the person inserts the tube portion 75 of the main body 71 into the inside of the ring fastener 150. As a result, each protrusion 153 enters each gap 77. Next, when the person rotates the main body 71 and the ring fastener 150 relatively in the circumferential direction CR of the tube portion 75, each protrusion 153 of the ring fastener 150 enters the mounting groove portion 78 from one end 66a of the guide rail 66. Furthermore, when a person rotates the main body 71 and the ring fastener 150 relatively in the circumferential direction CR of the tube portion 75, each of the multiple protrusions 153 slides on the sliding surfaces 68 of the respective guide rails 66 along the circumferential direction CR of the tube portion 75. When the main body 71 and the ring fastener 150 are relatively rotated, for example, by 15 degrees along the circumferential direction CR of the main body 62, each of the multiple protrusions 153 climbs over each of the multiple first restricting portions 67a disposed on the sliding surfaces 68. The movement of each of the protrusions 153 in the anti-circumferential direction ACR is restricted by each of the first restricting portions 67a that have climbed over.

Furthermore, when a person relatively rotates the main body 71 and the ring fastener 150 along the circumferential direction CR of the tube portion 75, for example by 15 degrees, each of the multiple protrusions 153 slides on the sliding surface 68 and climbs over each of the multiple second restriction portions 67b. The movement of each protrusion 153 in the anti-circumferential direction ACR is restricted by each of the second restriction portions 67b that it has climbed over.

Furthermore, when a person rotates the main body 71 and the ring fastener 150 relatively along the circumferential direction CR of the tube portion 75, for example by 15 degrees, each of the multiple protrusions 153 slides on the sliding surface 68 and overcomes each of the multiple third restriction parts 67c. The movement of each of the protrusions 153 in the anti-circumferential direction ACR is restricted by each of the multiple second restriction parts 67b that have been overcome. In order for each of the multiple protrusions 153 to overcome each of the multiple third restriction parts 67c, the angle at which the main body 71 and the ring fastener 150 are rotated relatively along the circumferential direction CR of the main body 71 is not limited to 15 degrees. For example, it is preferable that the angle be anywhere between 15 degrees and 20 degrees.

As shown in FIG. 42, each of the multiple protrusions 153, whose movement in the circumferential direction CR of the tube part 75 has stopped in the third stage, comes into surface contact with each of the multiple first restricting parts 67a and engages with them to be fixed. In this case, the fourth Peltier element unit 60D can be attached to the temperature control vest 1 in a state in which the fabric of the temperature control vest 1 having a thickness of X9 (for example, about 1 mm) is sandwiched between the upper surface 76 of the main body part 71 and the surface 154 of the outer flange 151. When removing the fourth Peltier element unit 60D, a person rotates the main body part 71 and the ring fastener 150 relative to the counter-circumferential direction ACR of the main body part 71, so that each of the multiple protrusions 153 overcomes each of the first restricting parts 67a to the third restricting parts 67c. This allows the Peltier element unit 60 to be removed from the temperature control vest 1. In this case, the person rotates the main body part 71 and the ring fastener 150 relatively to the counter-circumferential direction ACR of the main body part 71 by, for example, 45 degrees.

When each of the multiple protrusions 153 overcomes the third restricting portion 67c, each of the multiple protrusions 153 cannot overcome each of the multiple fourth restricting portions 67d even if a person rotates the main body portion 71 and the ring fastener 150 relatively in the circumferential direction CR of the tube portion 75. This makes it possible to prevent the fourth Peltier element unit 60D from falling off the temperature regulating vest 1 due to the relative rotation of the main body portion 71 and the ring fastener 150 in the circumferential direction CR of the tube portion 75.

When the fourth Peltier element unit 60D according to the third embodiment is attached to the vest body 2, first, each of the protrusions constituting the multiple (e.g., 4) protrusions 153 is inserted into the multiple (e.g., 4) gaps 70 in the axial direction L along the axial line AX of the main body 71. As a result, the upper surface 76 of the fourth Peltier element unit 60D and the ring fastener 150 sandwich the fabric of the temperature control vest 1. Next, the main body 71 and the ring fastener 150 are rotated relative to each other, and in a state in which the upper surface 76 of the fourth Peltier element unit 60D and the ring fastener 150 sandwich the fabric of the temperature control vest 1, the movement of each of the multiple protrusions 153 is restricted by the restricting portion 67 that they have overcome. Furthermore, each of the multiple protrusions 153 engages with each of the multiple restricting portions 54, and the air blowing unit 40 is attached to the temperature control vest 1. Therefore, a person can attach the Peltier element unit 60 to the temperature control vest 1 with a one-touch operation of the fourth Peltier element unit 60D. Furthermore, by rotating the main body 71 and the ring fastener 150 relatively, the locations at which the Peltier element unit 60 engages with each of the multiple protrusions 153 can be changed stepwise. As a result, for example, if the thickness of the fabric of the temperature control vest 1 is about 3 mm, the multiple protrusions 153 can engage with the first restricting portion 67a, and the fourth Peltier element unit 60D can be attached to the temperature control vest 1. For example, if the thickness of the fabric of the temperature control vest 1 is about 2 mm, the multiple protrusions 153 can engage with the second restricting portion 67b, and the fourth Peltier element unit 60D can be attached to the temperature control vest 1. For example, if the thickness of the fabric of the temperature control vest 1 is about 1 mm, the multiple protrusions 153 can engage with the third restricting portion 67c, and the fourth Peltier element unit 60D can be attached to the temperature control vest 1. Therefore, regardless of the thickness of the fabric of the temperature control vest 1, a person can attach the fourth Peltier element unit 60D to the temperature control vest 1 in accordance with the thickness. Therefore, it is easy to attach the fourth Peltier element unit 60D according to the third embodiment to the fabric of the temperature control vest 1, and the ease of use of the temperature control vest 1 can be improved. Furthermore, even if the back fabric 3B and the element mounting part 30 are repeatedly sandwiched between the upper surface 76 of the main body 71 and the ring fastener 150, the back fabric 3B and the element mounting part 30 can be made less susceptible to plastic deformation. Therefore, even if the fourth Peltier element unit 60D is attached to the temperature control vest 1, it is possible to prevent rattling and damage to the back fabric 3B and the element mounting part 30.

<Flow of Air Sucked Through Inlet 72a>
Changes in the flow of air sucked in from the intake port 72a will be described with reference to Fig. 43 and Fig. 44. Fig. 43 is a cross-sectional view for explaining the flow of air inside the fourth Peltier element unit of the comparative example. Fig. 44 is a cross-sectional view for explaining the flow of air inside the fourth Peltier element unit of the third embodiment.

As shown in Figures 43 to 44, the cooling fins 65a in the comparative example and the third embodiment are spaced apart at a fixed distance so that air flowing in from the air holes 64a can pass between the cooling fins 65a. As shown in Figures 43 to 44, the cooling fins 65a in the comparative example and the third embodiment are aligned in 12 vertical rows and 6 horizontal rows. This makes it easier for the cooling air that flows in between the cooling fins 65a to come into contact with the cooling fins 65a, allowing efficient exchange of heat from the Peltier element PE.

43 to 44, a blower device 100 is provided directly above the heat exchange surface 65 in the main body 71 according to the comparative example and the third embodiment. A part of the air sucked in from the intake port 72a is blown up in the same direction as the rotation direction KR of the exhaust heat fan 101 by the wind generated by the rotation of the exhaust heat fan 101 in the rotation direction KR, and is released from the release section 75b.

As shown in Figures 43 to 44, in the main body portion 71 according to the comparative example and the third embodiment, there is an internal space NB between the side portion 72 of the fourth Peltier element unit 60D and the heat exchange surface 65. In the internal space NB in the main body portion 71 in the comparative example, i.e., around the heat exchange surface 65, there is no flow guide portion 74 for guiding the air drawn in from the intake port 72a to the heat exchange surface 65. On the other hand, in the internal space NB in the main body portion 71 according to the third embodiment, i.e., around the heat exchange surface 65, there is a flow guide portion 74 for guiding the air drawn in from the intake port 72a to the heat exchange surface 65.

First, the change in the flow of air sucked in from the intake port 72a will be described with reference to FIG. 43. As shown in FIG. 43, in the fourth Peltier element unit 60D of the comparative example, a part of the air AR sucked in from the intake port 72a (AR8, AR12, AR13) comes into contact with the cooling fin 65a and is heat exchanged. Of the heat-exchanged air AR (AR8, AR12, AR13), the air AR8 is blown up in the same direction as the rotation direction KR of the exhaust fan 101 by the wind generated by the rotation in the rotation direction KR of the exhaust fan 101, and is released from the release section 75b. On the other hand, the heat-exchanged air AR12 and air AR13 remain in a stagnant state in the internal space NB. This interferes with the movement of the air AR newly sucked in from the intake port 72a, and the efficiency of releasing the air from the release section 75b is reduced.

43, a portion of the air AR (AR9, AR10, AR11, AR14) sucked in from the intake port 72a does not move toward the heat exchange surface 65 and remains stagnant in the internal space NB. As a result, a portion of the air AR sucked in from the intake port 72a remains stagnant in the main body 71 without moving toward the heat exchange surface 65, which reduces the efficiency of air release from the release section 75b.

Next, the flow guide section 74 will be described. In the fourth Peltier element unit 60D according to the third embodiment, the internal space NB is used between the side portion 72 of the fourth Peltier element unit 60D and the heat exchange surface 65, and 30 flow guide sections 74 are provided in the internal space NB. As shown in FIG. 44, the flow guide sections 74 are provided radially from the axial line AX of the blower device 100. The flow guide sections 74 are formed in an arc shape that curves toward the heat exchange surface 65 in the same direction as the rotation direction KR of the exhaust heat fan 101. As a result, as shown in FIG. 44, a part of the air AR (AR15 to AR21) sucked in from the intake port 72a comes into contact with the flow guide sections 74 and is changed to flow in the same direction as the rotation direction KR of the exhaust heat fan 101. That is, the flow guiding section 74 has a function of changing a portion of the air AR (AR15 to AR21) sucked in from the suction port 72a so that the portion flows in the same direction as the rotation direction KR of the heat exhaust fan 101 by bringing the portion into contact with the flow guiding section 74. Furthermore, by providing the flow guiding section 74 in the internal space NB, the intake resistance to the air AR sucked in from the suction port 72a is reduced, so that cooling air can be efficiently taken into the main body section 71 from the suction port 72a.

Next, the change in the flow of the air sucked in from the intake port 72a will be described with reference to FIG. 44. As shown in FIG. 44, a part of the air AR sucked in from the intake port 72a (AR15 to AR21) comes into contact with the flow guide 74 and flows in the same direction as the rotation direction KR of the exhaust heat fan 101. Then, a part of the air AR comes into contact with the cooling fin 65a and is heat exchanged. Then, the heat-exchanged air is rolled up in the rotation direction KR of the exhaust heat fan 101 and is released from the release section 75b. In the case where the flow guide 74 is arranged in the main body 71 according to the third embodiment, the proportion of the air sucked in from the intake port 72a and released from the release section 75b can be increased by about 10% compared to the case where the flow guide 74 is not arranged in the main body 71 of the comparative example.

Next, we will explain the function and effect of the temperature regulating vest 1 of this embodiment.

In the temperature control vest 1, a body temperature control device (air blower unit 40, Peltier element unit 60) capable of adjusting the body temperature of the wearer HM by the temperature control unit (Peltier element PE, fan 42) according to the first and second embodiments can be detachably attached to insertion holes (fan insertion hole 22, element insertion hole 32) formed in the fabric (fan outer peripheral edge portion 21, element outer peripheral edge portion 31) that constitutes the temperature control vest 1. The body temperature control device has an intake portion (inner case portion 45, air cylinder portion 64) in which air holes (air hole 46a, air hole 64a) that take in air are formed. The present invention relates to a main body portion (main body portion 41, main body portion 62) that is connected to the main body portion, a flange (flange 47, inner flange 63) that protrudes outward from the outer circumferential surface of the main body portion, a plurality of guide rails (guide rail 50, guide rail 66) that are provided in an arc shape along the outer circumferential surface of the main body portion between one end (one end 50a, one end 66a) and the other end (the other end 50b, the other end 66b) on the outer circumferential surface of the main body portion, and an annular fixing member (pressing member 110, relay 120) having a plurality of protrusions (protrusions 113, protrusions 122) that can be connected to the guide rails (guide rail 50, guide rail 66). Each of the plurality of guide rails has a plurality of restricting portions (restricting portion 54 (first restricting portion 54a, second restricting portion 54b, third restricting portion 54c, fourth restricting portion 54d), restricting portion 67 (first restricting portion 67a, second restricting portion 67b, third restricting portion 67c, fourth restricting portion 67d)) that restrict the movement of the protrusion, and the restricting portions are intermittently provided on a sliding surface (sliding surface 53, sliding surface 68) that connects one end and the other end, and the plurality of restricting portions include a first restricting portion (first restricting portion 54a, first restricting portion 67a) and a second restricting portion (second restricting portion 67b) that is provided closer to the other end than the first restricting portion. The body temperature regulating device has a first regulating portion 54b, a second regulating portion 67b), and a plurality of gaps (gap 51, gap 70) extending in the axial direction L along the axial line AX of the main body part are provided between the plurality of guide rails. The body temperature regulating device is attached to the fabric by inserting each of the plurality of protrusions into each of the plurality of gaps in the axial direction L along the axial line AX of the main body part, rotating the flange and the fixing member relatively, and sandwiching the fabric between the flange and the fixing member, whereby each of the plurality of protrusions engages with the first regulating portion or the second regulating portion.

According to this embodiment, the body temperature adjustment device (blower unit 40, Peltier element unit 60) is attached by inserting each of the multiple protrusions (protrusion 113, protrusion 122) into the multiple gaps (gap 51, gap 70) in the axial direction L of the main body part (main body part 41, main body part 62). As a result, the flange (flange 47, inner flange 63) and the fixing member (pressing member 110, ring fastener 120) sandwich the fabric of the temperature control vest 1. Next, the main body part and the fixing member are rotated relative to each other, and each of the multiple protrusions overcomes the first restricting part (first restricting part 54a, first restricting part 67a) or the second restricting part (second restricting part 54b, second restricting part 67b), and is engaged with the first restricting part. Therefore, a person can attach the body temperature adjustment device to the fabric (fan mounting part 20, element mounting part 30) of the temperature control vest 1 with a one-touch operation that gives a sense of moderation. Furthermore, since there is no insufficient fastening or loosening of the fastening members, it is possible to prevent the body temperature regulating device from falling off the temperature regulating vest 1 or losing only the fastening members. Therefore, it is possible to provide a clothing attachment structure for a body temperature regulating device that simplifies attachment of the body temperature regulating device to the fabric constituting the temperature regulating vest 1 and improves the ease of use of the temperature regulating vest 1, and a temperature regulating vest 1 constructed with this structure.

In addition, in the clothing attachment structure of the body temperature regulating device according to the first and second embodiments, each of the multiple guide rails (guide rail 50, guide rail 66) is formed in an inclined manner with a height difference ΔH by applying an inclination angle θ of 3°, as an example, to the axial direction L along the axial line AX of the main body portion (main body portion 41, main body portion 62) between one end (one end 50a, one end 66a) and the other end (other end 50b, other end 66b).

In the technology of Patent Document 1, depending on the thickness of the fabric of the air-conditioning garment between the main body of the air-conditioning garment blowing unit and the pressing member, the main body side and the pressing member side cannot be screwed together and firmly fixed, and the body temperature adjustment device falls off from the body temperature adjustment garment. In the technology of Patent Document 1, the flange and the pressing member are screwed together and fixed many times, which causes plastic deformation of the fabric around the opening of the fabric and damages the fabric. According to this aspect, when the fabric is about 3 mm thick, each of the multiple protrusions engages with the first restricting portion (first restricting portion 54a, first restricting portion 67a) when the fabric is sandwiched between the flange (flange 47, inner flange 63) and the fixing member (pressing member 110, ring fastener 120). On the other hand, when the fabric of the garment is about 2 mm thick, each of the multiple protrusions engages with the second restricting portion (second restricting portion 54b, second restricting portion 67b) when the fabric is sandwiched between the flange and the fixing member. This allows the body temperature regulating device to be worn with the fabric tightly sandwiched between the flange and the fastening member so that it will not fall off from the temperature regulating vest 1, regardless of the thickness of the fabric that constitutes the clothing. Furthermore, even if each of the multiple protrusions engages with the first or second restricting portion with the fabric sandwiched between the flange and the fastening member, the fabric around the insertion holes (fan insertion hole 22, element insertion hole 32) is unlikely to undergo plastic deformation. This makes it possible to prevent the body temperature regulating device from rattling and the fabric around the insertion holes from being damaged.

In addition, in the clothing attachment structure of the body temperature regulating device according to the first and second embodiments, the inclination angle θ of the sliding surfaces (sliding surfaces 53, 68) has, as an example, an inclination angle θ of 3° on the intake section (outer case section 46, air cylinder section 64) side with respect to a plane parallel to the axial direction L along the axial line AX of the main body section (main body section 41, main body section 62).

According to this embodiment, the relative rotation of the main body (main body 41, main body 62) and the fastening member (pressing member 110, ring fastener 120) causes each of the multiple protrusions (protrusion 113, protrusion 122) to slide on the sliding surface (sliding surface 53, sliding surface 68) having an inclination angle of 3°. This prevents the sandwiched fabric from interfering with the intake of air from the air holes (air holes 46a, air holes 64a), and prevents the fabric around the insertion holes (fan insertion hole 22, element insertion hole 32) from being damaged by sliding on each of the sliding surfaces of the multiple protrusions.

In the clothing attachment structure of the body temperature regulating device of the first embodiment, the temperature regulating unit is a Peltier element PE, and the body temperature regulating device has a cooling surface 61A and a heat exchange surface 65 opposite the cooling surface 61A, and is configured so that the cold heat present on the cooling surface 61A, which is absorbing heat, can be transferred to the body by the Peltier element PE when it is energized.

According to this embodiment, when the temperature regulating vest 1 is worn, the cooling surface 61A, which has absorbed heat due to the energized Peltier element PE, comes into contact with the body surface BS of the wearer HM directly or indirectly via underwear, etc. This makes it possible to efficiently cool only specific parts of the body surface desired by the wearer, such as parts that feel particularly hot or parts that are steamy in spots, by localizing the cooling.

The clothing attachment structure of the body temperature regulating device of the first embodiment is provided with a discharge section 62b that discharges air taken in through the air holes 64a, the heat exchange surface 65 has a plurality of cooling fins 65a, the air cylindrical section 64 has air holes 64a formed on its circumference, the cooling surface 61A and the air cylindrical section 64 are attached to the body side of the temperature regulating vest 1, and the inner flange 63 has an inclined surface on the discharge section 62b side at an angle of 15 degrees to 30 degrees with respect to a plane parallel to the cooling surface 61A.

According to this embodiment, the multiple cooling fins 65a of the heat exchange surface 65 of the Peltier element unit 60 are cooled by air taken in from the air holes 64a of the air cylinder portion 64. The air taken in from the air holes 64a is guided to the base of the multiple cooling fins 65a by the inner flange 63 having a surface 63a at an angle of 15 degrees to 30 degrees on the discharge portion 62b side with respect to a plane parallel to the cooling surface 61A. In other words, the cooling fins 65a can significantly increase the area for heat exchange, and further, by having the surface 63a at an angle of 15 degrees to 30 degrees on the inner flange 63, a part of the air flowing into the air holes 64a for cooling hits the inner flange 63 and flows downward. As a result, the flow of air flowing in below the inner flange 63 is changed to the base side of the cooling fins. Therefore, when the entire cooling air is viewed in plan of the cooling fins 65a, the cooling efficiency can be increased by about 10% compared to when the flanges are parallel. By increasing the cooling efficiency by about 10%, for example, in a configuration in which a motor is driven from the discharge section 62b to rotate the heat exhaust fan 101 and exhaust air, the power consumption of the motor can be reduced by about 10%. Furthermore, the effective cooling time of the temperature control device can be extended from 120 minutes to 132 minutes, for example. Therefore, by increasing the cooling efficiency of the Peltier element unit 60 while suppressing the power consumption of the Peltier element unit 60, the risk of heat stroke for workers working outdoors in extreme heat can be avoided.

In the clothing attachment structure of the body temperature regulation device of the second embodiment, the temperature regulation unit is a fan 42, and the air blowing unit 40 is configured to be able to blow either cold air, which is at a lower temperature than the outside air, or warm air, which is at a higher temperature than the outside air, onto the body of the wearer HM by rotating the fan 42.

According to this embodiment, for example, cool air (wind) can be supplied to workers working outdoors in extreme heat, workers working in humid indoor environments, and people engaged in recreation, sports, or watching events under the blazing sun, thereby preventing the onset of heat stroke. Conversely, when used in conjunction with a heat source, such as a hand warmer or simple heater, the outside air supplied to the blower unit 40 can be blown toward the heat source, and the warm air (wind) heated by the heat source can be blown toward the body, thereby warming up the chilled body.

This is a temperature regulating vest 1 to which a body temperature regulating device which constitutes the clothing attachment structure of the body temperature regulating device of the first to third embodiments is removably attached.

According to this aspect, the body temperature regulating device (blower unit 40, Peltier element unit 60) according to the first to third embodiments can be easily attached by inserting it into the insertion holes (fan insertion hole 22 and element insertion hole 32) in the fabric of the temperature regulating vest 1 that employs the clothing attachment structure. Furthermore, it is possible to provide the wearer with a user-friendly temperature regulating vest 1 that can be fitted with a body temperature regulating device that is compatible with any thickness of fabric.

Although the present disclosure has been described above with reference to embodiments, the present disclosure is not limited to the above embodiments and can be modified as appropriate without departing from the spirit and scope of the present disclosure.

In the above embodiment, the number of protrusions (protrusions 113, protrusions 122, protrusions 153) was four. However, this is not limited to this. For example, the number of protrusions (protrusions 113, protrusions 122, protrusions 153) may be three or less, or five or more. However, it is preferable that the number of protrusions (protrusions 113, protrusions 122, protrusions 153) is the same as the number of guide rails (guide rails 50, guide rails 66). This is because if the number of protrusions (protrusions 113, protrusions 122, protrusions 153) differs from the number of guide rails (guide rails 50, guide rails 66), it becomes difficult to attach the body temperature adjustment device (blower unit 40, Peltier element unit 60) to the temperature control vest 1.

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

In the above embodiment, the number of regulating portions (regulating portion 54, regulating portion 67) provided on each of the multiple sliding surfaces (sliding surface 53, sliding surface 68) was four. However, this is not limited to this. For example, the number of regulating portions (regulating portion 54, regulating portion 67) provided on each of the multiple sliding surfaces (sliding surface 53, sliding surface 68) may be three or less, or five or more.

In the above embodiment, the number of gaps (gap 51, gap 70, gap 77) was four. However, this is not limited to this. For example, the number of gaps (gap 51, gap 70, gap 77) may be three or less, or five or more.

In the above embodiment, when the multiple guide rails (guide rail 50, guide rail 66) are deployed on a plane, the inclination angle θ of each guide rail between one end (one end 50a, one end 66a) and the other end (the other end 50b, the other end 66b) is 3°. However, this is not limited to this. For example, the inclination angle θ between one end and the other end of the sliding surface (sliding surface 53, sliding surface 68) of all the multiple guide rails may be less than 3° or may exceed 3°. However, if the inclination angle θ 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 not be possible to accommodate various thicknesses of fabric. On the other hand, if the inclination angle θ is 10 degrees or more, it will be difficult to sandwich the fabric of the temperature control vest 1 and attach it to the temperature control vest 1, which is not preferable.

In the above embodiment, when the multiple guide rails (guide rail 50, guide rail 66) are deployed on a plane, one end (one end 50a, one end 66a) and the other end (the other end 50b, the other end 66b) are in a straight line. However, this is not limited to this. For example, when the multiple guide rails (guide rail 50, guide rail 66) are deployed on a plane, the inclination angle θ of the guide rail from one end to the first regulating portion (first regulating portion 54a, first regulating portion 67a) may be, for example, 5°. In this case, for example, when the multiple guide rails are deployed on a plane, the inclination angle θ of the guide rail from the first regulating portion to the second regulating portion (second regulating portion 54b, second regulating portion 67b) may be 2°. Furthermore, for example, when the multiple guide rails are deployed on a plane, the inclination angle θ of the guide rail from the second regulating portion to the third regulating portion (third regulating portion 54c, third regulating portion 67c) may be 1°. As a result, when the guide rails are deployed on a plane, they form a parabola between one end and the other end, and therefore the amount of movement of each of the protrusions can be made smaller when the protrusions reach the third restricting portion from the first restricting portion than when the protrusions reach the first restricting portion from the one end.

In the above embodiment, the restricting portion (restricting portion 54, restricting portion 67) was provided on the sliding surface (sliding surface 53, sliding surface 68) having an angle of 3° toward the intake portion (outer case portion 46, air cylinder portion 64). However, this is not limited to this. For example, the multiple guide rails (guide rail 50, guide rail 66) may be arc-shaped and extend in a stepped manner along the outer circumferential surface of the main body portion (main body portion 41, main body portion 62).

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, and various modifications are possible. 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, and various modifications are possible.

In the above embodiment, the inclination angle θ of the surface 63a and the back surface 63b of the inner flange 63 and the inclination angle θ of the surface 121a and the back surface 121b of the outer flange 121 were 20°. However, this is not limited to this. For example, the inclination angle θ of the surface 63a and the back surface 63b of the inner flange 63 in the above embodiment can be changed as appropriate as long as it is 15° or more and 30° or less. The inclination angle θ of the surface 121a and the back surface 121b of the outer flange 121 can be changed as appropriate as long as it is 15° or more and 30° or less. Note that if the inclination angle θ of the inner flange 63 is less than 15°, it is difficult to change the flow of air flowing into the air hole 64a by the inner flange 63 so that it is directed toward the base of the cooling fin 65a, which is not preferable. On the other hand, if the inclination angle θ of the inner flange 63 and the inclination angle θ of the outer flange 121 exceed 30°, the element outer peripheral edge portion 31 of the element mounting portion 30 will bend excessively near the ends located radially outward of the inner flange 63 and the outer flange 121. This is not preferable because it may cause damage to the element outer peripheral edge portion 31.

In the above embodiment, the inclination angle θ of the surface 63a and the back surface 63b of the inner flange 63 and the inclination angle θ of the surface 121a and the back surface 121b of the outer flange 121 were 20°. However, this is not limited to this. For example, the inclination angle θ of the surface 63a and the back surface 63b of the outer flange 121 may be larger than the inclination angle θ of the surface 63a and the back surface 63b of the inner flange 63. With this configuration, when the Peltier element unit 60 is attached to the element mounting portion 30, a part of the surface 63a of the inner flange 63 will be in contact with the element mounting portion 30 (for example, line contact, point contact). Therefore, the contact area between the element mounting portion 30 and the surface 63a of the inner flange 63 is smaller than in the above embodiment, and the surface pressure of the contact surface is larger. Therefore, it is possible to prevent the Peltier element unit 60 from coming off the element mounting portion 30 more effectively than when the surface 63a of the inner flange 63 and the surface 121a of the outer flange 121 are in surface contact with the element mounting portion 30.

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

In the above embodiment, the temperature regulating vest 1 is provided with an air blowing unit 40, but this is not limited to the above. For example, the temperature regulating vest 1 may be configured without an air blowing unit 40, and can be modified as appropriate.

In the above embodiment, the temperature of the cooling surface under heat absorption in the Peltier element is set to about 10°C as an example, but is not limited to such a temperature and may be, for example, a temperature range higher than zero°C and close to 10°C, and the heat absorption characteristics of the Peltier element can be changed as appropriate. Similarly, the temperature of the heating surface under heat generation is set to about 30°C as an example, but is not limited to such a temperature and may be, for example, a temperature of about 40°C, which is slightly higher than body temperature and does not cause burns, and the heat generation characteristics of the Peltier element can be changed as appropriate.

In the above embodiment, a vest body 2 is described in which element attachment parts 30 are provided at a total of three locations on the back fabric 3B of the fabric 3. However, this is not limited to this. The number, placement positions, and arrangement of element attachment parts 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.

As is clear from the above explanation, the clothing attachment structure of the body temperature regulating device disclosed herein, and the body temperature regulating clothing constructed with said structure, can simplify attachment of the body temperature regulating device to the fabric of the clothing, and can improve the ease of use of the body temperature regulating clothing. Therefore, it has industrial applicability.
